Abstract
Abstract
Objective
To identify practice patterns regarding human papillomavirus (HPV) vaccination efforts and vaccination rates in context of head and neck cancer prevention, identify barriers to vaccination, and identify gaps in knowledge regarding the link between HPV and head and neck cancer in the pediatrician population.

Study design/Methods
A 27-question cross-sectional survey was distributed to members of the four California chapters of the American Academy of Pediatrics.

Results
Of the completed responses, 89.4% identified as "always" recommending the HPV vaccine to patients, but only 19.5% of pediatricians estimated that >75% of their eligible patients had completed the HPV vaccination series. 71.5% of respondents felt that further education about HPV's link to head and neck cancer them more comfortable discussing vaccination. Physicians who were in practice longer were less likely to respond that additional education about HPV and its link to head and neck cancer would make them more comfortable discussing vaccination with patients (p = 0.043). Physicians who were in practice longer were more likely to correctly respond that HPV type 16 is the most common strain linked to head and neck cancer (p = 0.021).

Conclusion
There is need to improve both the knowledge base and comfort level of pediatricians in counseling their patients during vaccine recommendations. Otolaryngologists have a critical role in providing education to physicians, trainees, and the general public in the effort to combat the epidemic of HPV-associated head and neck cancer.

Abstract
Abstract
Objective
To investigate the genetic and epigenetic differences between human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) and HPV-negative OPSCC.

Methods
Microarray data of HPV-positive and -negative OPSCC were retrieved from NCBI GEO datasets. Differentially expressed genes (DEGs) and differentially expressed miRNAs (DE-miRNAs) were identified by performing differential expression analysis. A functional enrichment analysis was performed to explore the biological processes and signaling pathways that DEGs and DE-miRNAs were involved in, respectively. A protein-protein interaction (PPI) network of DEGs was constructed to identify hub genes. miRNA-target network and miRNA-miRNA functional synergistic network were each constructed in order to identify risk-marker miRNAs. An miRNA-target-pathway network was constructed in order to explore the function of identified risk-marker miRNAs.

Results
Microarray data from 3 datasets (GSE39366, GSE40774, and GSE55550) was included and analyzed. The PPI network identified 3 hub genes (VCAM1, UBD, and RPA2). MiR-107 and miR-142-3p were found to play the most significant role in both the DE-miRNA-target network as well as in the miRNA-miRNA functional synergistic network. MiR-107 was involved in HPV-induced tumorigenesis by targeting many genes (CAV1, CDK6, MYB, and SERPINB5) and regulating the p53 signaling pathway, the PI3K-Akt signaling pathway, and the autophagy pathway. In addition, miR-142-3p was implicated in HPV-induced tumorigenesis by targeting the PPFIA1 gene and regulating transcriptional dysregulation and other cancerous pathways.

Conclusion
Three genes (VCAM1, UBD, and RPA2), two miRNAs (miR-107 and miR-142-3p), and four pathways (p53, PI3K-Akt, autophagy, and transcription dysregulation in cancer) were identified to play critical roles in distinguishing HPV-positive OPSCC from HPV-negative OPSCC.

Abstract
Abstract
Purpose
As imaging technology improves and more thyroid nodules and malignancies are identified, it is important to recognize factors associated with malignancy and poor prognosis. Vitamin D has proven useful as a prognostic tool for other cancers and may be similarly useful in thyroid cancer. This study explores the relationship of Vitamin D to papillary thyroid carcinoma stage while accounting for socioeconomic covariates.

Materials and methods
The medical records of all patients who underwent thyroidectomy at one institution between 2000 and 2015 were reviewed. Subjects with non-papillary thyroid cancer pathology, prior malignancy, and without Vitamin D levels were excluded. The remaining 334 patient records were examined for cancer stage, Vitamin D levels, Vitamin D deficiency listed in history, and demographic and comorbid factors.

Results
Vitamin D laboratory values showed no significant relationship to cancer stage (p = 0.871), but patients with Vitamin D deficiency documented in the medical record were more likely to have advanced disease (28.6% versus 14.7%; p = 0.028). The patients with documented Vitamin D deficiency also had lower 25-hydroxyvitamin D nadirs (21.5 ng/mL versus 26.5 ng/mL, p = 0.008) and were more likely to be on Vitamin D supplementation (92.6% versus 41.8%, p < 0.001).

Conclusions
The results suggest that Vitamin D deficiency may have value as a negative prognostic indicator in papillary thyroid cancer and that pre-operative laboratory evaluation may be less useful. This is important because Vitamin D deficiency is modifiable. While different racial subgroups had different rates of Vitamin D deficiency, neither race nor socioeconomic status showed correlation with cancer stage.

Abstract
Abstract
Purpose
To evaluate the survival benefit of total laryngectomy (TL) after induction chemotherapy in locally advanced laryngeal cancer patients.

Materials and methods
This is a retrospective study utilizing the National Cancer Database, which captures >80% of newly diagnosed head and neck squamous cell carcinoma cases in the United States. We included patients diagnosed with advanced stage laryngeal squamous cell carcinoma between 2004 and 2013 (n = 5649) who received either TL (n = 4113; 72.8%) or induction chemotherapy followed by either radiation therapy (n = 1431) or TL (n = 105). Kaplan-Meier curves and Cox proportional hazards regression were used to evaluate overall survival. A Cox regression model was computed to examine how the prognostic impact of treatment differed by clinical stage.

Results
In multivariable analysis, when compared to patients receiving TL alone, those receiving induction chemotherapy followed by TL experienced no significant difference in survival (HR 0.85, 95% CI 0.63–1.13), while those receiving induction chemotherapy followed by radiation experienced poorer survival (HR 1.15, 95% CI 1.06–1.26). Induction chemotherapy followed by TL was associated with improved survival compared to induction chemotherapy and radiation (P = .042). Among patients with T4a tumors, TL (P < .001) and induction chemotherapy followed by TL (P = .002) were both associated with improved survival compared to induction chemotherapy and radiation. There were no survival differences between TL and induction chemotherapy followed by TL (HR 0.76, 95% CI 0.52–1.10).

Conclusions
Larynx preservation may be attempted without compromising survival in patients with locally advanced larynx cancer who fail induction chemotherapy and undergo TL.

Abstract
Abstract
Introduction
Epistaxis is a common condition with an estimated $100 million in health care costs annually. A significant portion of this stems from Emergency Department (ED) management and hospital transfers. Currently there is no data in the literature clearly depicting the differences in treatment of epistaxis between Emergency Medicine (EM) physicians and Otolaryngologists. Clinical care pathways (CCP) are a way to standardize care and increase efficiency. Our goal was to evaluate the variability in epistaxis management between EM and Otolaryngology physicians in order to determine the potential impact of a system wide clinical care pathway.

Materials and methods
A retrospective case study was conducted of all patients transferred between emergency departments for epistaxis over an 18-month period. Exclusion criteria comprised patients under 18 years old, recent sinonasal surgery, bleeding disorders, and recent facial trauma.

Results
73 patients met inclusion criteria. EM physicians used nasal cautery in 8%, absorbable packing in 1% and non-absorbable packing in 92% (with 33% being bilateral). In comparison, Otolaryngologists used nasal cautery in 37%, absorbable packing in 34%, and non-absorbable packing in 23%. Eighty percent of patients treated by an Otolaryngology physician required less invasive intervention than previously performed by EM physicians prior to transfer.

Conclusions
Epistaxis management varied significantly between Emergency Medicine and Otolaryngology physicians. Numerous patients were treated immediately with non-absorbable packing. On post-transfer Otolaryngology evaluation, many of these patients required less invasive interventions. This study highlights the variability of epistaxis treatment within our hospital system and warrants the need for a standardized care pathway.

Abstract
Abstract
Objective
To assess the utility of rapid parathyroid hormone (PTH) values in predicting transient post-operative hypocalcemia in patients with unplanned parathyroidectomy during total or completion thyroidectomy.

Methods
All patients who underwent total or completion thyroidectomy between January 2010 and January 2015 were reviewed. Incidences of post-operative hypocalcemia were compared in patients with and without unplanned parathyroidectomy. Unplanned parathyroidectomy was defined as intra-operative incidental or intentional parathyroidectomy. Logistic regression assessed for predictors of hypocalcemia and optimum amount of calcium supplementation.

Results
Thirty-eight (13.6%) patients had evidence of incidental parathyroidectomy and 39/280 (13.9%) patients had parathyroid autotransplantation intra-operatively. Central neck dissection and malignancy were identified as risk factors for unplanned parathyroidectomy (p = 0.001, p = 0.060). Patients with unplanned parathyroidectomy were more likely to have hypocalcemia (p = 0.002) and hypoparathyroidism (p < 0.0005). PTH value was the only significant predictor of hypocalcemia in these patients. In patients with a post-operative PTH of ≤15, initial calcium supplementation ≥ 1000 mg decreased the risk of hypocalcemia (p < 0.05).

Conclusion
Post-operative PTH value predicts hypocalcemia in patients undergoing total and completion thyroidectomy with unplanned parathyroidectomy. In patients with a post-operative PTH < 15, initial calcium supplementation with ≥1000 mg of elemental calcium is recommended.

Abstract
Abstract
Objectives
After the publication of large clinical trials, in January 2014 The U.S. Preventive Services Task Force (USPSTF) recommended annual lung cancer screening with low-dose CT in a well-defined group of high-risk smokers. A significant proportion of patients with laryngeal cancer (LC) meet the introduced criteria, and we hypothesized that clinical practice would change as a result of these evidence-based guidelines.

Methods
Retrospective chart review of patients diagnosed with LC and treated at Johns Hopkins Hospital who met USPSTF criteria for annual chest screening and were followed for at least 3 consecutive years in the years surrounding the introduction of screening guidelines (January 2010 to December 2017) was performed to identify those who had recommended screening CT chest.

Results
A total of 151 patients met the inclusion criteria of the study and were followed for a total of 746 patient-years. 184/332 (55%) patient-years in the pre-guidelines period and 246/414 (59%) in the post-guidelines period included at least one recommended chest imaging (CT or PET-CT; p = 0.27). 248/332 (75%) patient-years in the pre-guidelines period and 314/414 (76%) in the post-guidelines period included any radiological chest imaging (X-ray, CT or PET-CT; p = 0.72). Screening scans were ordered by OHNS (45%), Medical Oncology (31%), Radiation Oncology (8%), and primary care (14%) with 70% of patients missing at least one year of indicated screening.

Conclusions
The implementation of new lung cancer screening guidelines did not change clinical practice in the management of patients with LC and many patients do not receive recommended screening. Further study concerning potential barriers to effective evidence-based screening and coordination of care is warranted.

Abstract
Abstract
Objective
We aim to investigate hearing sensitivity and wideband tympanometry results in bone cement ossiculoplasty cases in present study.

Study design
A prospective study.

Setting
Ossiculoplasty patients were grouped according to the anatomical location of bone cement application by surgery note. Ossiculoplasty and tympanoplasty patients were retrospectively invited to the clinic and evaluated. 30 bone cement ossiculoplasty cases as well as 30 Type I tympanoplasty cases (intact ossicular chain) and 30 healthy controls were included in the study and Wideband Tympanometry was performed. Tympanometric peak pressure, equivalent middle ear volume, static admittance, tympanogram width, resonance frequency, average wideband tympanometry and absorbance measurements were analyzed.

Results
A statistically significant improvement was observed in the hearing levels of all ossiculoplasty and type I tympanoplasty patients (p < 0.05). Bone cement ossiculoplasty groups demonstrated the remarkable differences than the type I tympanoplasty and control group in Wideband Tympanometry test parameters. In some parameters, malleus-stapes and manubriostapedioplasty groups demonstrated similarities to Type I tympanoplasty and control groups.

Conclusion
Bone cement is an effective application for ossiculoplasty. Wideband tympanometry is a promising method for the evaluation of the middle ear dynamics.

Abstract
Abstract
Purpose
To examine the incidence of intracapsular hemorrhage in orbital fracture repair with non-fixated nylon sheet implants.

Methods
A retrospective chart review of 227 patients presenting from January 2013 to December 2016 for orbital fracture repair with nylon sheet implants.

Results
Of the 331 orbital fractures repaired over 4 years, a total of 227 met inclusion criteria. The average implant thickness was 0.38 mm and no implants were fixated. Four total implants (1.8%) were removed due to complications; one each secondary to exploration for ongoing postoperative diplopia, immediate post-operative orbital hemorrhage, a cystic mass anterior to the implant, and pain. There were no cases of intracapsular hemorrhage nor infection for any of the 227 patients over 4 years.

Conclusions
To the authors knowledge, this represents the largest case series to date to assess the rate of intracapsular hemorrhage in non-fixated nylon sheet orbital implants. In the 227 cases reviewed over a 4-year period, there were no cases of intracapsular hemorrhage. This suggests a much lower complication rate than previously reported.

Précis
A case series of 227 patients who underwent orbital fracture repair with non-fixated nylon sheet implants.

Abstract
Abstract
Thyroglossal duct cysts (TDC) are the most common congenital neck masses. Although they are anatomically closely related to the larynx, intra-laryngeal extension is very rare. We present a case, review the literature and discuss the challenges of intra-laryngeal TDC. A 55-year-old man presented with a neck mass associated with dysphagia. Computer Tomography neck scan showed a midline cyst extending to the pre-epiglottic space with partial obliteration of the right pyriform sinus and narrowing of the larynx. The cyst was excised en-bloc via Sistrunk procedure. Intra-laryngeal TDC are surgically challenging due to risk of perforation into the aerodigestive tract.

Abstract
Abstract
We present two unique cases of myoclonus-induced objective tinnitus (OT), along with a comprehensive literature review on the topic. Primary goals include: explore the relationship between palatal myoclonus (PM) and middle ear myoclonus (MEM), highlight the embryologic, neurologic, and anatomical relationship between the involved peri-tubular muscles, exemplify the first case of OT which documents video evidence demonstrating the link between objective tinnitus and eustachian tube movement. Also, we discuss available treatment interventions and why they often do not fully resolve patients' symptoms. Finally we introduce a novel way to objectively quantify the severity of OT. Ultimately, our series hopes to inform future diagnostic and treatment guidelines.

Abstract
Abstract
Purpose
Laryngeal squamous cell carcinoma (LSCC), a common type of head and neck cancer, is associated with high rates of metastasis and recurrence. In this study, we investigated the potential combinatorial prognostic value of NOTCH1, Vimentin (VIM), and Metastasis-associated 1 (MTA1) protein in LSCC, using immunohistochemistry.

Materials and methods
Tissue specimens from 69 patients with LSCC were immunohistochemically evaluated for the protein expression of NOTCH1, VIM, and MTA1. Then, biostatistical analysis was performed, in order to assess the prognostic value of the expression of each one of these proteins.

Results
NOTCH1 expression status was not a significant prognosticator in LSCC, as shown in Kaplan-Meier survival analysis. On the contrary, both VIM and MTA1 seem to have an important prognostic potential, independently of TNM staging and histological grade of the tumor. In fact, positive VIM expression was shown to predict patients' relapse and poor outcome regarding patients' overall survival, in contrast with MTA1, the positive expression of which predicts higher disease-free survival (DFS) and overall survival (OS) rates in LSCC.

Conclusions
VIM and MTA1 constitute potential tumor biomarkers in LSCC and could be integrated into a multiparametric prognostic model. Undoubtedly, their prognostic value needs further validation in larger cohorts of LSCC patients.

Abstract
Abstract
Background
Cervical chylous fistulae are rare complications usually occurring from iatrogenic injury to the thoracic duct. There have been no reported cases of spontaneous chyle leaks in surgical naïve necks.

Methods
Case report.

Results
A 50 year-old female presented with progressive left neck swelling without fever, dyspnea, or dysphagia. Imaging demonstrated extensive infiltrative changes of the left neck with retropharyngeal fluid extending into strap musculature and the mediastinum. Flexible laryngoscopy revealed posterior pharyngeal wall edema. Differential diagnosis included abscess versus necrotizing fasciitis. Broad-spectrum antibiotics were initiated and she was taken to the OR for neck exploration. Intra-operatively, milky fluid was present around the carotid sheath and in the retropharyngeal space. Fluid analysis demonstrated chylomicrons and triglycerides >2400 mg/dL. Repeat imaging of the neck, chest, and abdomen did not reveal malignancy or obstructive masses. A lymphangiogram showed dilated lymphatic vessels near the cervical thoracic duct. On post-operative day four, the patient was taken back to the OR for thoracic duct ligation and biopsy of nearby tissue. Pathology demonstrated benign lymph nodes with dilated sinusoids. A low-fat diet was started and she was discharged home on hospital day nine. She has followed up regularly with no signs of recurrence.

Conclusion
A cervical chylous fistula usually results from iatrogenic injury to the thoracic duct. To our knowledge, this is the first reported case of a spontaneous cervical chyle leak.

Abstract
Abstract
Purpose
Canalith repositioning procedure (CRP) for posterior canal benign positional paroxysmal vertigo (BPPV), also known as Epley maneuver, is a common procedure for the treatment of BPPV. This maneuver entails flexion, extension and rotation of the patient's neck. This study aims to investigate the impact of cervical range of motion (C-ROM) on CRP efficacy.

Materials and methods
The study included 47 patients with posterior canal BPPV treated by CRP. The procedure was considered successful if vertigo and nystagmus disappeared at the post-treatment evaluation. If CRP resulted ineffective, it was repeated up to three times per session. C-ROM was measured at BPPV diagnosis before treatment. Patients were followed up for 30 days.

Results
The first CRP was successful in 29 patients (61.7%), while it was ineffective in 18 patients (38.3%) requiring multiple repositioning maneuvers. Patients who needed two or more CRP showed lower C-ROM in extension (p = .003) and flexion (p = .042), and earlier recurrences (p = .006). Univariate regression analysis showed that lower cervical extension was significantly associated with the failure of the first CRP (OR: 0.899, 95% CI 0.831–0.973, p = .008).

Conclusions
Our data suggest that a reduced C-ROM can require multiple CRPs to successfully treat BPPV and increase the risk of early recurrences.

Abstract
Abstract
Background
There is much debate in the literature over the extent of surgery for patients with intermediate risk papillary thyroid cancer. We herein report our results in a local tertiary hospital.

Method
We identify from our database patients with papillary thyroid cancer who underwent surgery in our hospital and were stratified to be of intermediate risk from the GAMES stratification system. Patients' demographic data, surgical and pathological details were recorded. Primary end points were disease specific survival (DSS) and recurrence free survival (RFS).

Results
From January 1993 to December 2016, 231 patients with papillary thyroid cancer underwent surgery of which 137 (59%) were of intermediate risk. 45 (33%) patients had hemithyroidectomy and 92 (67%) patients had total thyroidectomy. In the total thyroidectomy group, patients had a higher tumor (T) (p value = 0.009) and nodal (N) staging (p value = 0.001). They were also predicted to have a higher risk of recurrence according to the American Thyroid Association (ATA) classification (p value = 0.005). The 5 year DSS in both groups were 100%. The 5 year RFS in the total thyroidectomy and hemithyroidectomy groups were 92% and 100% respectively and were significantly different by the log rank test (p value = 0.02). The median follow up time was 54 months (range 4–276 months).

Conclusion
The 5 year survival in intermediate risk papillary thyroid cancer is favorable. Hemithyroidectomy is an acceptable choice of operation in intermediate risk patients with a better risk profile.

Abstract
Abstract
Introduction
There are >400 million of native Spanish speakers around the world, being the second most spoken language in regard to the number of native speakers. For this reason, a valid questionnaire to access the quality of our patients after parotidectomy is necessary.

Material and methods
Validation and cross-cultural adaptation of the POI-8 questionnaire to the Spanish language. Internal consistency of Sp-POI 8 measured with Cronbach α.

Results
35 patients met the inclusion criteria during the mentioned period. Mean age was 59 ± 15,37 (Min: 18/Max: 87). 20 patients (57,1%) were male and 15 (42,9%) were female. Internal consistency with Cronbach α was 0.868. The intraclass correlation coefficient was 0.830 [CI] (95%: 0,791–925). Hypoesthesia was the most severely weighted problem (0,91) and xerostomia was the second (0,89). However, the high score was for fear of revision surgery (1,26).

Conclusion
The Spanish Language is the second most spoken language with regard to the number of native speakers and the Sp-POI 8 translation represents a valid option for the Spanish-speaking medical community, from which a large number of patients can benefit.

Abstract
Abstract
Objective
Enlargement of the vestibular aqueduct (EVA) is one of the most common congenital malformations in pediatric patients presenting with sensorineural or mixed hearing loss. The relationship between vestibular aqueduct (VA) morphology and hearing loss across sex is not well characterized. This study assesses VA morphology and frequency-specific hearing thresholds with sex as the primary predictor of interest.

Materials and methods
A retrospective, longitudinal, and repeated-measures study was used. 47 patients at an academic tertiary care center with hearing loss and a record of CT scan of the internal auditory canal were candidates, and included upon meeting EVA criteria after confirmatory measurements of vestibular aqueduct midpoint and operculum widths. Audiometric measures included pure-tone average and frequency-specific thresholds.

Results
Of the 47 patients (23 female and 24 male), 79 total ears were affected by EVA; the median age at diagnosis was 6.60 years. After comparing morphological measurements between sexes, ears from female patients were observed to have a greater average operculum width (3.25 vs. 2.70 mm for males, p = 0.006) and a greater average VA midpoint width (2.80 vs. 1.90 mm for males, p = 0.004). After adjusting for morphology, male patients' ears had pure-tone average thresholds 17.6 dB greater than female patients' ears (95% CI, 3.8 to 31.3 dB).

Conclusions
Though females seem to have greater enlargement of the vestibular aqueduct, this difference does not extend to hearing loss. Therefore, our results indicate that criteria for EVA diagnoses may benefit from re-evaluation. Further exploration into morphological and audiometric discrepancies across sex may help inform both clinician and patient expectations.

Abstract
Objective
Assess clinical and functional outcomes of a modified palisade cartilage-perichondrium graft myringoplasty under local in an office setting.

Study design
Retrospective case series.

Setting
Tertiary care facility.

Patients
Patients with a tympanic membrane perforation presenting between March 2013 and October 2017. Inclusion criteria included age ≥ 7 years, entire perforation margin visualized through a transcanal view, and the ability to lie supine for up to 45 min. Exclusion criteria included a conductive hearing loss larger than expected, and presence of active infection.

Intervention
In-office modified myringoplasty technique under local anesthesia without sedation.

Main outcome measures
Complete perforation closure rate and audiometric outcomes.

Results
250 patients underwent the procedure, of whom 13 had bilateral sequential procedures (total 263 ears). Of those, 197 were primary and 66 revision. Average age was 46.3 years. Perforation sizes were categorized as small (32), moderate (109), large (78), and subtotal (44). Complete perforation closure was evident in 219 of the 250 cases (88%). Preoperative mean air pure tone average (PTA) was 56.7 dB and mean bone PTA was 27.5 dB (pre-operative ABG 29.2 dB). AC-PTA significantly improved to 35.0 dB (p < 0.0001), and ABG to 9.6 dB (p < 0.0001). Only subtotal perforations showed a statistically significant negative relationship with outcome (p = 0.04).

Conclusion
The modified palisade cartilage-perichondrium graft myringoplasty under local anesthetic is a highly successful procedure well tolerated by adult and pediatric patients with variable perforation sizes. This may have significant potential patient benefits, as well as cost savings to the health care system.

Abstract
Abstract
Cricoarytenoid joint arthritis is an uncommon manifestation of rheumatoid arthritis. We encountered a 68-year-old woman with rheumatoid arthritis who presented with odynophagia, dysphagia, and progressive shortness of breath. Examination findings showed diminished mobility of the left vocal cord and right arytenoid swelling associated with an immobile right vocal cord. Computed tomography (CT) imaging identified a ring-enhancing lesion of the right lateral cricoarytenoid joint. Microdirect laryngoscopy with drainage of the cricoarytenoid abscess and tracheotomy were performed. Development of a laterally based cricoarytenoid joint abscess is identified as a complication of chronic rheumatoid arthritis with successful management described.

Abstract
Abstract
Background
Medialization laryngoplasty is a common procedure for voice rehabilitation in patients with unilateral vocal fold paralysis. Complications are uncommon and delayed infections involving implants are rare. We report a delayed infectious complication following an animal scratch resulting in a laryngocutaneous fistula.

Methods
Case report.

Results
A 73-year-old female underwent a successful and uneventful medialization laryngoplasty for idiopathic unilateral vocal fold paralysis using a silastic implant. More than one year after surgery, she presented with an anterior neck infection following an animal scratch with CT neck findings of a left strap muscle abscess. After incision and drainage, cultures grew methicillin-resistant Staphylococcus aureus. Despite culture-directed antibiotic therapy, the neck continued to drain persistently. Laryngoscopy with stroboscopy revealed a medialized vocal fold with no obvious granulation tissue and normal mucosal pliability.

The patient underwent neck exploration revealing a laryngocutaneous fistula. Thus, both the fistulous tract and implant were removed. The wound was closed with a strap muscle advancement into the laryngoplasty window. One month after surgery and antibiotics, the patient had no signs of recurrent neck infection, with a well-healing wound and stroboscopic findings of complete glottic closure, symmetric vocal fold oscillation and acceptable phonation with mild supraglottic compression.

Conclusions
Delayed complications of medialization laryngoplasty are rarely reported. This case demonstrates a delayed infection of a laryngeal implant after an animal scratch requiring implant removal, local tissue reconstruction, and culture-directed antibiotic therapy.

Mobolanle R Balogun, Oluchi A Okpalugo, Adedoyin O Ogunyemi, Adekemi O Sekoni

Nigerian Medical Journal 2017 58(4):123-130

Background: Breastfeeding is a child survival intervention, which is effective in reducing child mortality. This study compared the knowledge, attitude, and practice of breastfeeding among mothers of under-five children in rural and urban communities of Lagos, Southwest Nigeria. Methods: This comparative cross-sectional study was conducted in Ikeja and Ikorodu, an urban and a rural local government area (LGA) of Lagos state, respectively. A total of 248 mothers of children under 5 years were selected from both areas using multistage sampling technique and subsequently interviewed. Data were analyzed using the Statistical Package for the Social Sciences version 20. Chi-squared test was used for urban and rural comparisons. Results: The respondents with good level of knowledge of breastfeeding in the urban and rural areas were 84.7&#37; and 89.5&#37;, respectively (P &#61; 0.256). The overall positive attitude was 52.4&#37; and 57.3&#37; among the urban and rural respondents, respectively (P &#61; 0.444). More than three-quarters (75.8&#37;) of the respondents in the rural LGA and 43.5&#37; of the urban respondents initiated breastfeeding immediately after birth (P &#60; 0.001). Most of the rural respondents who had babies aged 0&#8211;24 months (46.8&#37;) were currently breastfeeding their babies compared to 25.9&#37; of their urban counterparts (P &#61; 0.001). Furthermore, 79.8&#37; of the rural respondents had practiced or were currently practicing exclusive breastfeeding (EBF) compared to 29.0&#37; of the urban respondents (P &#60; 0.001), with more urban women citing work resumption as reason for nonpractice of EBF (P &#61; 0.010). The overall good practice was 16.1&#37; and 69.4&#37; among the urban and rural respondents, respectively (P &#60; 0.001). Conclusion: Respondents&#39; knowledge about breastfeeding was good, while their attitude was fair. The practice of breastfeeding among urban respondents was however low. Government and nongovernmental agencies should focus on programs that improve the attitude and breastfeeding practice of urban women.

Nigerian Medical Journal 2017 58(4):131-137

Background: Reports comparing the values of white blood cells (WBCs) and platelet parameters among normotensive, newly diagnosed hypertensive, and known hypertensive participants in Nigeria are relatively scarce. This study sought to compare these hematologic parameters of normotensive and hypertensive participants in the Southeastern Nigeria. Materials and Methods: Fifty participants each of normotensive, newly diagnosed hypertensive, and known hypertensive and age- and sex-matched individuals were recruited into the study. Using an automated hematology analyzer, the following hematological parameters were determined in all participants: total WBC; neutrophil, lymphocyte and platelet counts; percentage value of neutrophil and lymphocytes; mean platelet volume (MPV); platelet distribution width; and total lymphocyte count. Results: Significantly higher total WBCs and (absolute) neutrophil counts and lower percentage lymphocyte were observed among known hypertensive male participants, whereas percentage neutrophil was significantly higher among known hypertensive female participants. Platelet count and MPV were significantly higher in hypertensive male participants compared to their normotensive counterparts. MPV was found to be significantly lower in hypertensive female participants compared to normotensive females. Conclusion: The present study reports significantly higher leukocytes, platelet counts, and MPV among hypertensive males and lower MPV among hypertensive females. Regular assessment of hematological parameters may perhaps be useful indicators of the prognosis of hypertension among the study population.

Nigerian Medical Journal 2017 58(4):138-142

Background: In the last few decades, the evaluation of the quality of life (QoL) among older adults has become increasingly important in health as well as in social sciences. There has been growing emphasis on the need to understand what influences older people&#39;s QoL as it is argued to be of greater value than the traditional outcome measures, such as health status. Aim and Objective: The aim of this study was to determine the sociodemographic factors affecting the QoL of elderly patients attending the General Outpatient Clinics of the University of Uyo Teaching Hospital (UUTH), Uyo. Methodology: The study was a cross-sectional descriptive study. Three hundred and ten elderly persons attending the General Outpatient Clinics of the UUTH for medical conditions between July and September 2014 were consecutively recruited for the study. Details of sociodemographic information were taken, and QoL of respondents was assessed using the older persons&#39; QoL questionnaire. Data were analyzed using the Statistical Package for Social Sciences-17.0, and the level of statistical significance was set at P &#60; 0.05. Results: Of the three hundred and ten respondents recruited for the study, One hundred and seventy-seven (57.1&#37;) were female and one hundred and thirty-three (42.9&#37;) were male. The female-to-male ratio was 1.3:1. The age range of the respondents was between 60 and 90 years and the mean age (&#177;standard deviation) was 67.4 (&#177;6.6) years. Two hundred and thirty-two respondents (74.8&#37;) had at least primary level of education and one hundred and sixty-one (51.9&#37;) were married. The median monthly income was &#8358; 25,500.00 with interquartile range of &#8358; 10,000.00 to &#8358; 50,000.00. From the study, 85.5&#37; of the elderly reported an overall good QoL. High-income grade (P &#61; 0.019), high social class (P &#61; 0.036), and high level of education (P &#60; 0.001) were the factors associated with good QoL in this study on univariate analysis. Conclusion: A high percentage of respondents reported an overall good QoL. High-income grade, high social class, and high level of education were the factors associated with good QoL.

Nigerian Medical Journal 2017 58(4):143-148

Background: Menstruation can be associated with dysmenorrhea that may affect daily activities. This study aimed to determine the prevalence of dysmenorrhea, effects on school activities, and associated school absenteeism among secondary school girls in Ibadan, Nigeria. Materials and Methods: This cross-sectional study was among 460 students from all girls&#39; only secondary schools in Ibadan, Nigeria, using a cluster sampling method. Data were collected using questionnaires and focus group discussions. The severity of dysmenorrhea was categorized as mild, moderate, and severe. Data collected were analyzed using descriptive statistics and Chi-square tests performed to determine significant associations. Level of statistical significance was set at 5&#37;. Results: Prevalence of dysmenorrhea and school absenteeism was 73&#37; and 13.1&#37;, with the severity of dysmenorrhea being 37.5&#37;, 43.8&#37;, and 18.8&#37; for mild, moderate, and severe dysmenorrhea. Other school activities affected were as follows: class concentration, class participation, social, and sports activities (17.6&#37;, 12.2&#37;, 10.9&#37;, and 4.6&#37;). Main sources of medication for pain relief were family (15.8&#37;) and self (13.7&#37;). Age and duration of menstruation predicted dysmenorrhea (odds ratio [OR] &#61;3.5, confidence interval [CI] &#61; 1.2&#8211;9.7, P &#61; 0.019), (OR &#61; 1.7, CI &#61; 1.1&#8211;2.6, P &#61; 0.022), whereas severe dysmenorrhea predicted school absenteeism (OR &#61; 4.2, CI &#61; 1.7&#8211;9.9, P &#61; 0.001). Respondents opined that analgesic drugs should be available in school to prevent school absenteeism. Conclusion: Prevalence of dysmenorrhea was high and severe dysmenorrhea played a role in school absenteeism. Health education should be provided to address the dangers of self-medication while drugs for pain relief should be available in schools.

Background Tuberculosis (TB) is an infectious disease affecting the world population for thousands of years. Aim The aim was to study and compare the pattern of TB in Suez and Damietta Chest Hospitals through the period from 2007 to 2016. Patients and methods This is a retrospective study that was carried out at Damietta and Suez Chest Hospitals and dispensaries and included all cases of TB from January 2007 to December 2016. Data were collected from TB registration units. Direct observed therapies strategy in chest hospitals and dispensaries started since January 1999. Results A total of 1208 (62.3%) cases were men and 732 (37.7%) were women. The highest rate of infection was reported in age group of 20&#8211;29 years (45.7%); the lowest affected age group was that greater than 60 years (5.1%). Type of TB was pulmonary in 76.1% and extrapulmonary in 23.9%. The main presenting symptom was cough presented in 50.8%, hemoptysis in 20.3%, chest pain in 14.7%, and fever in 14.2%. The sputum smear was positive in 89.3% and negative in 10.7%; and there was significant increase of positive smear in Damietta when compared with Suez Governorates (92.1 vs. 86.2%, respectively). The most common extrapulmonary lesion was pleural effusion (40.5%); then lymph node (19.4%) and the least was cold abscess (2.6%). Diabetes was reported in 11.5% and prolonged corticosteroid therapy in 6.5%. The condition at discharge was improvement in 85.5%, failure in 6.6%, relapse in 4.8%, and death in 3.1%. Both groups were comparable as regards the studied variables. Conclusion There was progressive decrease of total TB cases in both Damietta and Suez Governorate from 2007 to 2016 and both governorates were comparable.

Ismail M.A Ahmed, Hesham S Abdelraouf

Al-Azhar Assiut Medical Journal 2018 16(4):327-332

Background Pneumoperitoneum during laparoscopic surgery is associated with significant hemodynamic changes represented by increasing heart rate, vascular resistance, and blood pressure. This study aimed to compare the safety of each of magnesium sulfate, dexmedetomidine, and lignocaine on hemodynamic responses during pneumoperitoneum. Patients and methods In all, 120 patients were enrolled in the study. They were electively planned for laparoscopic cholecystectomy. Their ages were in the range of 21&#8211;60 years. Men were 38.3% and women 61.67%. American Society of Anesthesiologists I: 74.17% and II: 25.83%. The patients were randomly allocated into four groups: each of 30 patients. Group M administered magnesium sulfate preoperatively as loading followed by infusion 50&#8201;mg/kg/h, group D received dexmedetomidine preoperatively as loading followed by infusion 0.5&#8201;&#181;g/kg/h, group L was given lignocaine preoperatively as loading followed by infusion 1&#8201;mg/kg/h, and group C received normal saline. Results A significant difference was noticed as regards heart rate changes and mean arterial blood pressure increase between the groups of magnesium sulfate, dexmedetomidine, lignocaine, and the control group at the time of drug administration, after intubation, throughout pneumoperitoneum at 5&#8201;min intervals, postpneumoperitoneum, and in the postoperative period after 10&#8201;min (P&#60;0.001). Conclusion Magnesium sulfate and dexmedetomidine infusions have comparable effects. Lignocaine was less effective in the attenuation of the hypertensive response of pneumoperitoneum and reducing the dose requirements of opioids during laparoscopic cholecystectomy.

Al-Azhar Assiut Medical Journal 2018 16(4):333-342

Objectives To evaluate the outcome of septoplasty and the effect of bilateral anterior nasal packing (NP) on surgical outcome and postoperative (PO) arterial blood gas levels. Patients and methods A total of 90 patients underwent septoplasty: group I included patients who received PO bilateral anterior NP at the end of surgery for 48&#8201;h and group II included patients free of NP. Patients were evaluated clinically using the Nasal Obstruction and Septoplasty Effectiveness scale and underwent septoplasty using Cottle&#8217;s technique. Arterial blood samples were obtained preoperatively and before NP removal for estimation of arterial blood pH, bicarbonate (HCO3&#8722;), partial pressure of O2 (PaO2) and CO2 (PaCO2), and O2 saturation (SaO2) levels. Pain severity was assessed using numeric rating scale at 6&#8201;h, D-1, and D-2 PO, and during the first 48&#8201;h PO, nasal bleeding in group II was estimated. After NP removal, pack removal-associated pain and amount of bleeding were determined. Results Operations were conducted uneventfully with nonsignificant difference between groups. At 48&#8201;h PO, mean PaO2, PaCO2, and SaO2 levels were significantly lower in all patients than preoperative levels, with significantly lower SaO2 and PaCO2 levels in patients of group I than group II. Numeric rating scale pain scores in both groups showed progressive significant decrease till 48&#8201;h PO, with significantly lower scores in group II. Removal of NP resulted in pain scored by more than or equal to 4 in 30 patients and induced minimal bleeding, which was significantly lower than bleeding occurred in patients of group II throughout the 48&#8201;h PO. All patients enjoyed significant reduction of Nasal Obstruction and Septoplasty Effectiveness score, with nonsignificant difference between both groups. Conclusion NP after septoplasty reduced amount of PO bleeding, but pain associated with NP presence and removal-induced deleterious effect on patients&#8217; satisfaction with deleterious effect on arterial blood O2 and CO2 levels but with nonsignificant effect on arterial blood pH or HCO3 concentration.

Yousry Kandil

Al-Azhar Assiut Medical Journal 2018 16(4):343-348

Background Dexmedetomidine is a highly selective (eight time more selective than clonidine), specific, and potent &#945;2-adrenergic agonist having analgesic, sedative, antihypertensive, and anesthetic sparing effects when used in systemic routes. Patients and methods Forty patients of both sexes, aged between 25 and 70 years; American Society of Anesthesiologists I&#8211;II, who were submitted to elective upper limb surgery by supraclavicular brachial plexus block were included in the present study. They were selected during the period from March 2016 to June 2017. The patients were divided randomly by sealed envelopes into two equal groups (n&#61;20). Group I: 20 patients received 30&#8201;ml bupivacaine 0.25%. Group II: 20 patients received 30&#8201;ml bupivacaine 0.25% plus 100&#8201;&#956;g dexmedetomidine. Results The duration was reported in group II 13.13&#177;1.10 and 16.50&#177;1.63&#8201;min for the onset of sensory and motor blocks, respectively, and in group I 14.90&#177;1.18 and 18.63&#177;1.12&#8201;min for the onset of sensory and motor blocks, respectively. There was significant decrease of median pain score in group II when compared with group I at 4, 8, 12, 16, 20, and 24&#8201;h postoperatively. Conclusion Dexmedetomidine had significantly better postoperative analgesic effects, longer duration of sensory and motor blockade, and earlier onset of action. However, it had unwanted side effects in the form of transient bradycardia and hypotension.

Ashraf Abdelkader, Mohamed M Shaaban, Mahmoud Zahran

Al-Azhar Assiut Medical Journal 2018 16(4):349-355

Background Pediatric intensive care unit (PICU) has a specific location for the management of seriously ill children. Aim of the work The purpose of the study was to compare two models [Pediatric Risk of Mortality III (PRISM III) and the Pediatric Index of Mortality 3 (PIM3) scores] for the prediction of mortality in PICU in KSA. Patients and methods A prospective, cohort study was conducted and two mortality scores, PRISM III and PIM3, were applied on 68 children admitted to the PICU at As-Salama Hospital, Al Khobar, KSA over a period of 1 year from January till December 2016. Results The mean age was 7.6&#177;5.3 years with more men than women and the mean length of hospital stay was 9.8&#177;7.0 days. The overall expected mortality using the PRISM III score was 6.7% whereas that by PIM3 was 7.4% and the observed mortality was 17.6%. Both tests underpredicted mortality at all probability levels. However, the degree of underprediction was less when the predicted mortality was more than 25%. Both tests showed excellent discrimination with a value of 0.94 (95% confidence interval, 0.86&#8211;1.0) with 94.1% sensitivity and 72.0% specificity; and of 0.93 (95% confidence interval, 0.87&#8211;0.99) with 82.4% sensitivity and 84.0% specificity, respectively. The Hosmer and Lemeshow goodness-of-fit test showed good calibration for PRISM III score (&#967;2&#61;4.57, P&#61;0.148) but poor calibration for PIM3 score (&#967;2&#61;8.66, P&#61;0.01). Conclusion Both PRISM III and PIM3 scores underpredicted mortality at all probability levels. They offered good discrimination; however, the performance of the scoring system in the PICU patients was poor. PRISM III score showed good calibration while PIM3 score showed poor calibration. 


Cerebral microembolization in patients with prosthetic valve and anticoagulation assessment using transcranial Doppler ultrasonography
Mohamed A Zaki, Mohamed EL Sayed Moussa

Al-Azhar Assiut Medical Journal 2018 16(4):356-359

Background Transcranial Doppler detection of microemboli is widely described, and thromboembolism is a major cause of morbidity in patients with prosthetic heart valves. They require lifelong anticoagulation to minimize thrombotic complications. This study was undertaken to assess the clinical relevance of microembolic signals (MESs) and their relation to anticoagulation. Patients and methods Thirty patients with single mitral mechanical prosthetic valve were included. All of them were selected with low intensity of international normalization ratio (INR). After 2-week interval, INR intensities were stabilized to the recommended levels. Transcranial Doppler monitoring for MES detection was done to the same patients, before and after the stabilization of INR intensities. Results Microemboli were detected in 86.7% of patients before and after the INR level adjustment, with mean number of 57.63&#177;13.12 before adjust. The numbers were significantly lowered after the adjustment of INR, as the emboli number became 24.1&#177;9.12. Conclusion Compared with previously thought findings, the study results were different, as there was a significant effect of the anticoagulation on the number of MESs detected in patients with mechanical valve replacement, but without effect in MES incidence, denoting that, there were a variety of MESs rather than thrombotic. Further assessment by MES differentiation to define solid ones will be indicated.

Mohammed S Tawfeeq, Salah M Ibrahim, Somia H Abd Allah, Randa S Gomaa, Alaa E Salama, Reham M WahidEldin

Al-Azhar Assiut Medical Journal 2018 16(4):360-370

Background Ischemic heart diseases are considered as the first cause of death around the world. Mesenchymal stem cells are considered to be a novel therapy that can achieve real success in myocardial infarction (MI). Objective Evaluating the homing capability of human umbilical cord blood stem cells (HUCBSCs) in the injured myocardium and its role in the development of MI in adult male rats. Materials and methods Fifty adult male albino rats were divided into five groups (n&#61;10): control, MI, MI pretreated with HUCBSCs, MI posttreated with HUCBSCs within 24&#8201;h, and MI posttreated with HUCBSCs within 1 week. Serum cardiac troponin I and creatine kinase-myoglobin binding levels were evaluated to assess MI induction. Gene expression of human &#946; actin gene was assessed to evaluate HUCBSCs homing and rat caspase-3 gene was assessed to evaluate apoptosis. Myocardial histopathological examination was done to assess fibrosis. Echocardiographic left ventricular dimensions and function and mean arterial blood pressure were assessed. Results &#946; actin gene expression was higher in all HUCBSCs injected groups compared with normal and MI groups. Administration of HUCBSCs decreased caspase-3 gene expression and fibrosis and improved cardiac function and mean arterial blood pressure in all HUCBSCs injected groups compared with the MI group and these effects were more in pretreated group than both posttreated groups. Expression of rat caspase-3 gene, histopathological assessment, and echocardiography results showed more improvement in posttreated within 24&#8201;h group than posttreated within 1-week group. Conclusion HUCBSCs have high homing capability in injured myocardium and they could be used as a preventive therapy in case of ischemia to protect the heart from implications of MI. Moreover, it could be an effective therapy especially if administered within 24&#8201;h after MI. Further studies are recommended to highlight the preventive role of HUCBSCs and its clinical application especially in cases of unstable angina. 


The effect of 'cytochrome P-450 2C9' and 'vitamin K epoxide reductase complex 1' genetic polymorphism upon oral anticoagulation requirements
Hossam Y.K Mohammed, Yousry Z Al-Zohairy, Mahmoud Abd El-Latif Hashish

Al-Azhar Assiut Medical Journal 2018 16(4):371-376

Background Polymorphisms in the gene encoding the cytochrome P-450 2C9 enzyme (CYP2C9) are known to contribute to variability in sensitivity to Marevan. CYP2C9 is the enzyme primarily responsible for the metabolic clearance of s-enantiomer of Marevan. The vitamin K epoxide reductase complex 1 (VKORC1) is the target of coumarin anticoagulants, and its common genetic variants result in altered sensitivity to Marevan. VKORC1 polymorphisms are associated with a need for lower doses of Marevan during long-term therapy. Aim of work This study aimed to assess the allelic frequencies and to investigate the relationship between &#8216;CYP2C9&#8217; and &#8216;VKORC1&#8217; genotype and vitamin K antagonist anticoagulation. Patients and methods This study was conducted on 40 patients. There were 24 females and 16 males, with a male to female ratio of 2 : 3. Their ages ranged from 28 to 72 years. All the studied patients were laboratory investigated with international normalized ratio, complete blood count, and detection of VKORC1 and CYP2C9 by PCR reverse hybridization method using PGX thrombo strip assay (Vienna Lab.). Results Regarding the distribution of patients according to frequency of deep venous thrombosis (DVT) attacks, 16 (40%) patients showed single attack of DVT and 24 (60%) patients showed recurrent attacks. Patients with single attack of DVT comprised 12 (75%) females and four (25%) males, with male to female ratio of 1 : 3. As for the patients with recurrent attacks of DVT, there were 13 (54.2%) female and 11(45.8%) male patients, with a male to female ratio of 1 : 1.2. Conclusion Detection of genetic polymorphisms in CYP2C9 and VKORC1 genes before onset of warfarin therapy greatly influenced response to warfarin and shortened the time required to reach target international normalized ratio, and hence reduced the risk of recurrence of DVT. 


Comparative study between cervical polyetheretherketone cages and dynamic cervical implant postanterior cervical discectomy
Mostafa G Eldin, Mohammed S Mohammed

Al-Azhar Assiut Medical Journal 2018 16(4):377-385

Objective This is a prospective comparative study between polyetheretherketone (PEEK) cages and dynamic cervical implants (DCI) to evaluate the safety, the effectiveness, and the clinical outcome with radiological outcome for patients with single-level degenerated cervical disc disease treated by anterior cervical discectomy. Patients and methods We studied 30 patients with single-level cervical disc disease. Preoperative evaluation included plain cervical radiography including dynamic views. MRI was carried out to confirm the clinical diagnosis. Results Our study showed that the procedures of two groups were safe and easy without major complications and do not show significant differences between DCI and anterior cervical discectomy and fusion (ACDF) with PEEK cages in terms of improvement in clinical symptoms, blood loss, or operation time; however, DCI was associated with better postoperative neck disability index scores and also resulted in better overall cervical range of motion and segmental range of motion at the treated level than ACDF with PEEK cage. ACDF with PEEK cage is still the gold standard technique for treatment of cervical degenerative disc disease. It improves patient activity and provides a stable segment. However, it fails to restore normal cervical biomechanics and does not prevent adjacent segment disease. Conclusion DCI is considered as a new strategy and an intermediate stage between ACDF and total disc replacement. 


Infraclavicular brachial plexus block using nalbuphine versus midazolam as adjuvants to bupivacaine in upper limb surgery
Mohamed Abdel Gawad Abdel Halim

Al-Azhar Assiut Medical Journal 2018 16(4):386-391

Background Brachial plexus block is a regional anesthesia technique for different surgeries in the upper limb. It is useful as a sole regional anesthesia technique or combined with general anesthesia. The adjuvants to local anesthetics may be improving the quality and duration of analgesia of the brachial plexus block. Objective To evaluate the efficacy of nalbuphine and midazolam as adjuvants to bupivacaine in the infraclavicular brachial plexus block. Patients and methods The study was carried out on 70 patients of the American Society of Anesthesiologist, physical status I, II of both sexes, 20&#8211;60 years old and scheduled to forearm and hand surgeries. The patients were classified into three equal groups. Group B: using 20&#8201;ml of bupivacaine (3&#8201;mg/kg) with 1&#8201;ml of saline. Group M: using 20&#8201;ml of bupivacaine (3&#8201;mg/kg) with midazolam 5&#8201;mg (1&#8201;ml). Group N: using 20&#8201;ml of bupivacaine (3&#8201;mg/kg) with nalbuphine 1&#8201;ml (10&#8201;mg). Results The onset time of sensory and motor blocks were significantly shorter in the adjuvant groups N and M compared with group B. There was a significant increase in the duration of postoperative analgesia in group N compared with groups M and B. Conclusion The addition of nalbuphine and midazolam to bupivacaine in the infraclavicular brachial block improves the speed of sensory and motor onset, the quality of anesthesia, and decreases the analgesic requirements during the first 24&#8201;h postoperatively without obvious side effects. The addition of nalbuphine to bupivacaine was superior in delaying the postoperative analgesia requirement.

Sreekanth Bose, R Yashoda, Manjunath P Puranik

Journal of Dental Research and Review 2019 6(1):3-8

Background: Fluorosis is an endemic disease prevalent in 22 states in India affecting 70 million individuals. The process of removal of fluoride ions from water is known as defluoridation. Even though several defluondation techniques have been developed and implemented in India, most of these techniques have many disadvantages. Development of a newer defluoridation technique starts With laboratory experimentation of materials. Objectives: To identify recent advances in laboratory studies in India with regard to the materials used for defluoridation (published from 2010-2017). Methodology: The review was carned out according to the Joanna Briggs Institute (J81) critical appraisal guideline. A three-step search strategy was utilized which yielded twenty articles after the final step. These articles were evaluated to describe, compare and contrast the materials (Chemical, indigenous and herbal) in terms of effectiveness of fluonde removal, critical pH, cost and other factors. Results: Fluoride removal capacity varied around to 100&#37; and optimum pH between 2 to 10 in different studies. Indigenous and herbal materials are cost effective compared to chemicals. But chemicals have better defluoridation capacity. The defluondating properties can be enhanced using certain combinations or pretreatment of these materials (eg-Heat activation). Conclusions: Indigenous and herbal products are suitable for Indian conditions because of the ease of availability and cost-effectiveness. The future research should focus on enhancing the defluoridating properties of locally available materials and field studies regarding the feasibility in real life scenarios.

Nilofar B Attar, Rajesh P Gaikwad, Akshaya B Banodkar, Gulnar D Sethna

Journal of Dental Research and Review 2019 6(1):9-12

Context: Ultrasonic scaling is a routinely performed procedure in dental practice. During ultrasonic scaling, sensitivity of teeth is a common occurrence. The sensitivity of teeth causes discomfort and pain to many patients. The potassium nitrate is an antihypersensitivity agent used effectively in dentifrices. Aims: The aim of the study is to evaluate the efficacy of 5&#37; potassium nitrate gel application on the reduction of sensitivity during ultrasonic scaling. Settings and Design: This study is a randomized controlled trial with a split-mouth design. A total of 100 patients were recruited in the study after informed consent. Subjects and Methods: Mandibular anterior teeth were selected as the area for study. About 5&#37; potassium nitrate gel was applied to the left or right side of the teeth. After 5 min, ultrasonic scaling was performed for both test and control sides. Visual analog scale (VAS) and patient satisfaction were recorded for both the groups. Statistical Analysis Used: An unpaired t-test was used to analyze the mean VAS scores with the area treated with or without application of 5&#37; potassium gel during ultrasonic scaling. Chi-square test was used to analyze the satisfaction level with the test and control group. Results: The mean VAS scores and patient satisfaction for the test group were (P &#60; 0.001) statistically significant as compared to the control group. Conclusions: Potassium nitrate gel can be effectively used before ultrasonic scaling to reduce sensitivity.

Journal of Dental Research and Review 2019 6(1):13-18

Aim: To evaluate and compare the efficacy of chemomechanical method using Carie-Care (Eco Works Pvt. Ltd.) and conventional method (airotor and hand instruments) during excavation of caries in young permanent molar teeth. Methodology: Twelve children in the age group of 6&#8211;9 years having moderate occlusal caries in any two first permanent molars according to the ICDAS-3 or 4 category were selected. Caries excavation in Group I was carried out by the conventional method using airotor and hand instruments. In Group II, it was carried out using Carie-Care gel. The findings recorded in the study included pain response during caries excavation using the Wong-Baker Faces Pain Scale (WBFPS), time taken for caries excavation using a stopwatch (Taksun TS-1809), and the need felt for administration of local anesthesia in children for both the methods. Results: Data obtained were subjected to statistical analysis. Intergroup comparison for WBFPS scores and time needed for caries excavation was done using unpaired t-test and the results obtained were statistically highly significant (P &#60; 0.01). Conclusion: It was concluded from the present study that the use of Carie-Care resulted in reduced pain response from the children during caries excavation. Thus, it can be used as an alternative to the conventional method in children with dental phobia to achieve better cooperation and maintain a positive dental attitude for future treatment.

Road traffic-related injuries need to develop capacity building to provide comprehensive care
Amrita Ghosh, Ranabir Pal, Sagar Galwankar, Swapan Kumar Paul, Debashis Sinha, Shrayan Pal, AK Jaiswal, Luis Rafael Moscote-Salazar, Amit Agrawal

International Journal of Academic Medicine 2019 5(1):12-18

Every year around the world, millions die on road generally from preventable causes and are major public health threat in current times with soaring figures of unnecessary and unacceptable burden of morbidity and disability. We attempted an extensive collection of published literature with specific inclusion criteria in PubMed, Cochrane, Web of Science, and WHO Global Health Library including additional search in indexed literature and website-based population survey reports. Ten percent of road accident fatalities worldwide occur in India, and in addition, more than a million are grievously injured every year. Moreover, victims with nonfatal injuries are forced to live with a range of physical and emotional disabilities with a colossal social and economic impact. In addition, the health-care costs allied with these injuries also create an immense threat to the already stretched out curative health-care load particularly in resource-poor settings of the developing third world countries. Notwithstanding such sobering data, road traffic injuries received less than optimal interest from national health planners to provide comprehensive care from primary health-care levels where maximum injuries come as first contact intervention. Injuries are not accidents and they do not occur by chance alone; like morbidity, they follow a classical model of epidemiological triad of agent-host-environment. Hence, by classifying the risk factors for injury as modifiable and nonmodifiable, it is most likely to forecast and prevent by models. There is a great need to validate brain injury biofluid biomarkers in the acute care setting such as in the emergency departments. The following core competencies are addressed in this article: Medical knowledge, Patient care and procedural skills, and Systems-based practice.

Jameson M Petrochko, Andrew C Krakowski, Colin Donnelly, John B Wilson, Jennifer Bruno Irick, Stanislaw P Stawicki

International Journal of Academic Medicine 2019 5(1):19-50

As tattoos become more common, it is likely that practitioners will encounter adverse tattoo reactions with increasing frequency. While some tattoo-related complications (TRCs) may be nonspecific and challenging to diagnose, others present overtly and can be identified quickly by a well-informed practitioner. TRCs occur at both of these extremes, highlighting the need for better awareness and knowledge sharing regarding this heterogeneous group of morbidities. This review is a result of a compilation of the best available clinical evidence across various groupings of TRCs. The authors&#39; intent was to provide the reader with a comprehensive overview of the topic while creating a rich repository of referenced knowledge for future investigations. From the standpoint of frontline health-care providers, effective recognition and management of TRCs require an open-mind, high degree of clinical suspicion, and nonjudgmental approach to a mainstream phenomenon that is still considered by many to be a taboo. The following core competencies are addressed in this article: Medical knowledge, Patient care, and Systems-based practice.

Rebecca Jeanmonod, John Tran, Dhanalakshmi Thiyagarajan, Bryan Wilson, Jason Black, Saira Agarwala, Donald Jeanmonod

International Journal of Academic Medicine 2019 5(1):51-56

Introduction: Predicting early need for trauma resuscitation is an important goal of trauma systems. Aim/Hypothesis: We sought to compare the predictive value of end-tidal carbon dioxide (EtCO2) compared to hemoglobin, shock index, systolic blood pressure, heart rate, and respiratory rate in determining transfusion requirement, need for operative hemorrhage control, or pressor use in the first 24 h after trauma alert activation. Materials and Methods: A convenience sample of trauma patients at a Level 1 community trauma center were enrolled. EtCO2 was measured via nasal cannula upon arrival, in addition to initial hemoglobin levels and vital signs. Once stable and competent, patients or families were consented. EtCO2 average over three measurements 3 min apart was used as the EtCO2 value. The electronic medical record was reviewed by a trained research associate who was not involved in the care of the patient to determine the need for transfusion, pressor use, or operative hemorrhage control within the first 24 h of hospitalization. Results: Fifty patients were enrolled, with a median age of 52 years. Seven patients required transfusion, pressor use, and/or surgical hemorrhage control. Vital signs between groups were statistically no different. The mean EtCO2 in patients requiring transfusion was 26.8 (19.5&#8211;34.1) versus 34.1 (31.8&#8211;36.3) in those who did not (P &#61; 0.027). A cutoff value of EtCO2 &#8804;33 mmHg was 100&#37; sensitive and 62.8&#37; specific, with an area under the curve of 0.889. Conclusion: EtCO2 has a high sensitivity in predicting the need for intervention in trauma patients. Additional research is needed to determine further utility of this value in the triage and treatment of trauma patients. The following core competency statement: Patient care and Systems-based practice.

Benjamin Kaufman, Bryan Jarrett, Pia Daniel, Joseph Freedman, Christina Bloem, Bonnie Arquilla

International Journal of Academic Medicine 2019 5(1):57-61

Objective: This study evaluates the effectiveness of a novel modality created by our team to teach disaster preparedness consisting of tabletop drills and disaster simulation. Based on the Incident Command System (ICS) framework, our system prepares medical providers to respond independently to country-level disasters. Background: Disaster response remains an important component of emergency preparedness internationally. To this end, the ICS provides a standardized approach to the command, control, and coordination of emergency response. Methods: A 2-day workshop was conducted with medical providers in Bangalore, India, that used serial disaster simulations to improve disaster response using the ICS. Through increasing responsibility and self-directed tabletops, the participants (doctors, medical students, nurses, and police) gained the skills to respond independently to a simulated countrywide disaster. After the exercise, they were asked to grade the usefulness of simulation and lectures. Results: Forty-four providers responded to the questionnaire, all of which (n &#61; 44, 100&#37;) recommended the course. They graded the final disaster drill as most useful (n &#61; 36, 82&#37;) and also graded lectures from topic experts as useful (n &#61; 36, 83&#37;). Based on qualitative written feedback, participants felt drills helped them in communication and leadership. Conclusion: This novel teaching modality, using simulation and tabletop drills, is an effective tool to teach the ICS to medical providers. Participants felt that they benefitted from training and would respond better to future disasters. The following core competencies are addressed in this article: Systems-based practice, Patient care, Interpersonal and communication skills.

Peter F Johnston, Pamela Jumbo-Cueva, Varsha Kurup, Aparna Govindan, Somnath Rao, Ziad C Sifri

International Journal of Academic Medicine 2019 5(1):62-66

Background: Similar to previous models for recovery and donation of clean and unused operating room (OR) supplies, that would otherwise be discarded, a new program was started at our institution in 2016. Subsequently, the initiative was expanded to units outside the OR. This study aims to explore the output of these other units on top of our current program. We hypothesize that expansion is feasible and productive, with minimal added effort. Materials and Methods: Clean and unused supplies, in original packaging or open box, which would otherwise be discarded were collected in marked bins from the OR, Surgical Intensive Care Unit (SICU), and the trauma bay (TB) of our urban, academic center. Supplies were sorted, weighed, and inventoried weekly by qualified volunteers. Totals were calculated through proprietary inventory software. Results: The program salvaged 9024 individual items of 129 unique types grouped into 7 categories. In total, 1065 kg of supplies worth an estimated &#36;20,550 USD were collected from the three patient care areas over 7 months. Adding the SICU and TB resulted in a 33&#37; increase in recovered weight and 13&#37; increase in value. Twenty-nine new items were added to our inventory. If this program was expanded to recover supplies from the other ICUs in our hospital, we estimate an additional 951 kg worth &#36;9443 USD could be collected. Conclusions: Thousands of clean, unused supplies, weighing over a metric ton, are discarded in our hospital annually. The OR is the largest source of such material; however, expanding beyond the OR generates significant additional yield. Expansion is feasible with minimally added volunteer hours. Supply recovery initiatives undertaken nationwide and may help mitigate the economic and environmental costs associated with excess medical waste generation and produce staggering quantities of supplies for donation.

Complex necrotizing soft-tissue infections managed with extra-corporeal membrane oxygenation: 10-year follow-up
Melissa E Pastoressa, Blake Haxton, Michael S Firstenberg

International Journal of Academic Medicine 2019 5(1):67-70

The use of extracorporeal membrane oxygenation (ECMO) was initially used to support patients in acute cardiopulmonary failure, but its utility has expanded to include a broadspectrum of patients with complex medical conditions. As a growing number of cases continue to mount to prove its successes, ECMO has emerged as a versatile treatment modality in a wide range of clinical scenarios. While the literature documents many successes regarding short-term outcomes, long-term data are lacking. We previously reported two separate cases of profound septic shock where ECMO was implemented as rescue therapy and both patients were able to be successfully discharged. We now provide an update to one of those cases to demonstrate long-term meaningful outcomes in a case where ECMO was utilized successfully. The following core competencies are addressed in this article: Medical knowledge, Patient care and procedural skills, and Systems-based practice. 


Academic succession planning: A US perspective
Thomas J Papadimos

International Journal of Academic Medicine 2019 5(1):71-74

Succession planning for the replacement of vacant academic leadership positions is of paramount importance. It permits organized and minimally disruptive changes during times of transition. Interim chairs have become more common because of increasingly high chair turnover rates and the declining tenure of sitting chairs. In the U.S. nearly 66&#37; of new chairs come from the department of the home institution. Therefore, training faculty members within the department who have the desirable attributes required to be strong leaders will be of assistance to an institution during the turbulent times created by transitions. An emphasis should be placed on the importance of the development of interim chairs as leaders. The following core competencies are addressed in this article: Systems-based practice, Interpersonal and communication skills, and Professionalism. 


Learning process and how adults learn
Ravi Prakash, Neha Sharma, Uma Advani

International Journal of Academic Medicine 2019 5(1):75-79

Learning is a process of changing behavior of learner. Teaching&#8211;learning process lasts the entire life span of each individual. Adult education is the intentional systematic process of teaching and learning by which person who occupies adult role acquires new value, attitude, knowledge, skill, and discipline. Art and science of helping adults in learning is called andragogy. Adult learners are autonomous, self-directed, reluctant to learn new things, and they focus mainly on immediate implementation of knowledge. The theories to explain adult learning are conditioning theory, theory of connectionism, and cognitive theory. Adult learning knowledge in medical education helps to keep update for recent advances in different fields. To improve teaching&#8211;learning, the principles of adult learning should be applied like active involvement of learner by allowing debate and challenge of ideas using audience response system technique. The adult learner should always be motivated and reinforced by positive feedback. Adults are usually goal oriented; so, we should always relate learning to participant&#39;s goal. The following core competencies are addressed in this article: Medical knowledge, Practice-based learning and improvement, Professionalism, Systems-based practice.
