Abstract
Objective
We previously established the head-tilt subjective visual vertical (HT-SVV) test to evaluate head-tilt perception gain (HTPG) in addition to the original head-upright SVV (HU-SVV) test (Wada-Y et al.: Laryngoscope Investig Otolaryngol, 2020). In this study, we aimed to investigate the HU-SVV and HT-SVV abnormality rates among patients with vertigo/dizziness.

Methods
Between July 2014 and December 2020, 357 patients were hospitalized for examining the HU-SVV and HT-SVV at our vertigo/dizziness center. Among these patients, 120 had Meniere's disease (MD), 99 had unilateral vestibular disease (UVD), 76 had benign paroxysmal positional vertigo (BPPV), 14 had vestibular migraine (VM), 13 had orthostatic dysfunction (OD), 12 had bilateral vestibular disease (BVD), 12 had central dizziness (CD), 7 had vestibular schwannoma (VS), and 4 had psychogenic dizziness (PD). We determined the reference values of the absolute HU-SVV (<2.5°) and HTPG (0.80–1.25) for the sitting position and used these for calculating the HU-SVV and HT-SVV abnormality rates in each type of vertigo/dizziness.

Results
Among the 357 patients, 111 had abnormal HU-SVV results (31.1%), 132 had abnormal HT-SVV results (37.0%), and 185 had abnormal HU-SVV and/or HT-SVV results (51.8%). The modified HT-SVV test in combination with the original HU-SVV test could detect gravity perception disturbance in patients with vertigo/dizziness significantly better than the original test alone (chi-square: p=0.00019). The HU-SVV, HT-SVV, and HU-SVV and/or HT-SVV abnormality rates were significantly higher in patients with peripheral vestibular diseases, i.e., MD, UVD, BPPV, and BVD than in those with other types of vertigo/dizziness, i.e., VM, OD, CD, VS, and PD (chi-square: p=0.010, p=0.020, and p=0.0025, respectively).

Conclusion
These findings suggest that the combined HT-SVV and HU-SVV test could be a powerful neuro-otologic examination for detecting pathologies in the vestibular otolithic pathway.

Recurrent Giant Mucoepidermoid Carcinoma of the Parotid: A Case Report and Review of Literature

xlomafota13 shared this article with you from Inoreader

Abstract

Mucoepidermoid carcinoma is the most common salivary gland malignancy and about one third occurs in the parotid gland. The peak incidence is commonly seen between the third and fifth decades of life. It routinely presents as a fixed, painless mass below the ear. However, its presentation as a giant mass is exceedingly rare. Here, we report a case of a recurrent giant exophytic mucoepidermoid carcinoma in a young male. He underwent Revision Total Parotidectomy with Modified Radical neck dissection with Sural nerve grafting and an Anterolateral thigh flap reconstruction followed by Adjuvant radiotherapy. The rarity of the clinical presentation and the management challenges faced in a young male are being discussed in this case report.

Text
A 13-year-old male presented to the pediatric otolaryngology clinic with a 2-year history of a right neck mass that had slowly increased in size. He denied any associated symptoms of pain, fevers, chills, malaise, night sweats, unintentional weight loss, prior history of neck masses, recent upper respiratory tract infections, or skin lesions. He was the product of a full-term pregnancy with up-to-date immunizations. Physical examination revealed a 2.5-cm firm, ovoid, mobile, and nontender mass at the apex of the posterior triangle of the right neck without any associated overlying skin changes. The remainder of the head and neck examination was unremarkable. Doppler ultrasonography revealed a 1.9 × 1.8 × 0.9-cm hypoechoic mass, and subsequent fine-needle aspirates demonstrated cells with elongated nuclei and eccentric blue cytoplasm in a background of myxoid stroma. The mass was excised in entirety without issue. At the time of surgery, the deep surface of the mass was foun d to be adherent to the sternocleidomastoid muscle. The lesion was resected with a cuff of muscle and sent for permanent histopathological examination. This revealed proliferation of bland spindle cells with plump nuclei and eosinophilic cytoplasm arranged as loose fascicles in a background of myxoid stroma (Figure 1). These cells were positive for mucin 4 (MUC4), epithelial membrane antigen (EMA), and transducing-like enhancer of split 1 (TLE1) immunohistochemical stains. Fluorescence in situ hybridization (FISH) revealed a positive FUS (16p11) gene rearrangement.

Message:

Do children with nonsevere obstructive sleep apnea experience resolution of nocturnal enuresis after adenotonsillectomy?

Findings In this econdary analysis of a randomized clinical trial including 393 of the 453 totally enrolled children, those with nonsevere obstructive sleep apnea, those who underwent adenotonsillectomy were more likely to experience resolution of nocturnal enuresis compared with children who did not receive surgery. Nocturnal enuresis was less frequent in girls; other clinical factors, such as age, obesity, and severity of sleep apnea, were not associated with improvement of nocturnal enuresis.

Meaning The findings of this study suggest that it may be useful for clinicians to inquire about nocturnal enuresis in children with obstructive sleep apnea and counsel caregivers on the potential benefit associated with adenotonsillectomy.

Abstract
Importance Children with obstructive sleep apnea (OSA) are at increased risk for nocturnal enuresis (NE). However, randomized clinical trials assessing NE outcomes in children randomized to adenotonsillectomy (AT) vs watchful waiting are lacking.

Objective To assess the outcomes of AT vs watchful waiting in children with nonsevere OSA who experience NE.

Design, Setting, and Participants Secondary analysis of data from a multicenter randomized clinical trial conducted at tertiary children's hospitals was performed. Participants included 453 children aged 5.0 to 9.9 years with nonsevere OSA who were randomized to either watchful waiting or AT as part of the multicenter Childhood Adenotonsillectomy Trial. Caregivers completed the Pediatric Sleep Questionnaire, which includes a binary item on bed-wetting, at baseline and 7-month follow-up. The trial was conducted between October 2007 and June 2012. Evaluation in this secondary analysis involving NE occurred from October 2019 to March 2021.

Interventions Adenotonsillectomy vs watchful waiting in children with NE.

Main Outcomes and Measures Prevalence of NE as defined by parental response to the Pediatric Sleep Questionnaire bed-wetting item at baseline and 7-month follow-up.

Results Of the 453 children enrolled, 393 were included in analysis; of these, 201 were girls (51.1%). Mean (SD) age at baseline was 6.54 (1.40) years. At baseline, the number of children with NE was similar (2.6%; 95% CI, −0.12% to 0.07%) between the AT (59 [30.7%]) and watchful-waiting (67 [33.3%]) groups. The odds of NE in the watchful-waiting group were approximately 2 times higher than the AT group after 7 months (odds ratio, 2.0; 95% CI, 1.3 to 3.1). Following AT, there was a decrease (−11.0%; 95% CI, −16.3% to −5.7%) in the number of children with NE (n = 38). The prevalence of NE did not change significantly (−0.5%; 95% CI, −5.4% to 6.4%) in the watchful-waiting group (n = 66) at follow-up. Although NE was less frequent in girls (adjusted odds ratio, 0.53; 95% CI, 0.33-0.85), other clinical factors, such as age, race and ethnicity, obesity, and apnea-hypopnea index, were not associated with improvement of NE.

Conclusions and Relevance In this secondary analysis of a randomized clinical trial, AT for the treatment of pediatric OSA appears to result in improvement in NE. Further research is needed to assess whether AT is associated with long-term benefits for NE compared with watchful waiting.

Nodular Mass in the Earlobe of an 18-Month-Old Girl

xlomafota13 shared this article with you from Inoreader

Message:

An 18-month-old girl presented with a 1-year history of a slow-growing mass in the right earlobe. There were no symptoms, such as tenderness or discharge, associated with the mass. She had no history of underlying medical disease or trauma. On physical examination, a 1.5 × 1.0–cm, firm, nodular, angulated, pinkish, nontender mass was observed in the posterior aspect of the right earlobe (Figure, A). The skin over the mass was semitransparent, and the mass moved freely beneath the skin. Under suspicion of a tumorous lesion, complete excision was performed after the patient received general anesthesia. Histopathologic findings were characteristic for 2 cell types; basaloid cells with a nucleus were present in the periphery, and ghost cells without a nucleus were present in the center (Figure, B). Six months after surgery, the wound had healed well, and there has been no recurrence.

xlomafota13 shared this article with you from Inoreader

Message:

An 80-year-old woman presented with a 1-year history of right pulsatile tinnitus and aural fullness. Her symptoms were more prominent at night and in the quiet and improved when upright. Physical examination demonstrated an intact tympanic membrane with no middle ear mass; there was no neck mass palpated or bruit auscultated. The patient had further workup with magnetic resonance imaging (MRI) and a computed tomographic scan (Figure 1). The patient was taken to the operating room for a right transtemporal biopsy. Operative findings demonstrated extensive tumor extending along the posterior fossa dura and deep to the jugular foramen that filled the area of the skull base. The tumor was debulked and sent for pathologic evaluation.
