Online ahead of print. ABSTRACT Objective: To evaluate the clinical efficacy of topical nasal Pomegranate Fruit Extract (PFE) for Chronic Rhinitis (CR), Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP), and Chronic Rhinosinusitis without Nasal Polyposis (CRSsNP). Methods: Prospective, double-blinded, randomized study including 111 consecutive patients, between April 2012 and Ja nuary 2017, afflicted by CRSwNP, CRSsNP, and CR. Patients from each group were randomly assigned to either PFE treatment or placebo twice daily for 30 days. Therapeutic efficacy was assessed by Ear Nose and Throat, blood and tomographic examinations, and the SNOT-20 questionnaire. Results: CR patients treated with PFE suffered significantly less from thick nasal discharge, difficulty falling asleep, reduced productivity, reduced concentration, and sadness (P = .004, P = .02, P = .03, P = .007 and P = .02, respectively). Conclusions: Topical nasal PFE was found to have some benefits for CR patients, however, not for CRS with or without Nasal Polyposis.

xlomafota13 shared this article with you from Inoreader Rupture of a superficial temporal artery pseudoaneurysm following craniotomy Via leak of cerebrospinal fluid J Surg Case Rep. 2021 Sep 8;2021(9):rjab379. doi: 10.1093/jscr/rjab379. eCollection 2021 Sep. ABSTRACT Pseudoaneurysm of the superficial temporal artery (STA) is a rare entity that has been reported in the literature after trauma or iatrogenic injuries. We describe a unique case of STA pseudoaneurysm rupture and the clinical sequelae associated with its rupture. We report a case of pseudoaneurysm rupture of the STA that occurred 14 days after craniotomy for cerebrospinal fluid leak repair. We also review the literature, diagnosis and treatment of external carotid artery aneurysms. Rupture of a STA pseudoaneurysm is a previously unreported and serious complication that must be quickly recognized in order to control hemorrhage that may have life threatening complications.

xlomafota13 shared this article with you from Inoreader Parapharyngeal Lymph Node Metastasis From Papillary Thyroid Carcinoma Via ear nose throat Ear Nose Throat J. 2021 Sep 24:1455613211045566. doi: 10.1177/01455613211045566. Online ahead of print. ABSTRACT Metastatic parapharyngeal lymph nodes (LNs) from papillary thyroid carcinomas (PTC) are uncommon and can easily remain undetected. We describe a case that involves a 62-year-old woman treated for a PTC, who presented a rise in serum thyroglobulin (TG) levels. A computed tomography scan was performed, and revealed metastatic nodes in the left parapharyngeal space (P PS). A surgical resection of the nodes was performed with external cervical approach. A histological exam confirmed the diagnosis of a metastatic LN of a PTC. The aim of this report is to emphasize on the possibility of parapharyngeal metastatic nodes in PTC and to describe the diagnosis methods, treatment options, and impact on the prognosis.

xlomafota13 shared this article with you from Inoreader Effects of hyaluronic acid on the bone healing after lateral osteotomy: an experimental animal model Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Sep 24. doi: 10.1007/s00405-021-07096-7. Online ahead of print. ABSTRACT OBJECTIVE: Postoperative comfort of the patients undergoing rhinoplasty might be poor because of edema and ecchymosis caused by lateral osteotomy. In this animal experiment, we aimed at performing a quantitative assessment of effects of hyaluronic acid usage on healing process of lateral osteotomy. METHODS: Fourteen New Zealand rabbits with a weight of 2000-2500 kg and an age of 8-12 weeks were included. Under anesthesia, nasal dorsums were exposed with midline incision and lateral osteotomies on both sides were performed using a 2 mm chisel. A hyaluronic acid-based mesh (Hyalonect®) (1 × 1 cm) was embedded on the left osteotomy areas of all rabbits. Right osteotomy areas were left blank as control group. Collagen density and capillary development were quantitatively compared. RESULTS: Convergence of fractur e lines was observed in 6 (60%) of 10 samples from Hyalonect® group, while was observed in 4 (40%) of 10 samples from control group. Although a higher rate of convergence was seen in the Hyalonect® group (60% vs 40%), the difference was not statistically significant (p = 0.5). Median collagen score was 2 (1-3) in the Hyalonect® group and 1 (1-2) in the control group. Median capillary count value was 4 (1-23) in the Hyalonect® group and 3 (1-17) in the control group. Both collagen score and capillary count values were significantly greater in the in the Hyalonect® group compared with the control group (p = 0.023 and p = 0.019, respectively). CONCLUSION: The effects of hyaluronic acid-based meshes on the bone healing process of the lateral osteotomy area might be investigated furthermore, on more comprehensive studies, as a material facilitating collagen organization and capillary development.

Trends in Adjuvant Therapy After Surgery for Oropharyngeal Squamous Cell Carcinoma

xlomafota13 shared this article with you from Inoreader Trends in Adjuvant Therapy After Surgery for Oropharyngeal Squamous Cell Carcinoma Via The Laryngoscope Objectives/Hypothesis We aim to 1) evaluate trends in adjuvant treatment of human papilloma virus (HPV)-related oropharyngeal cancer; 2) assess change in complications and functional outcomes over time; and 3) assess change in overall and disease-free survival (DFS) over time. Study Design Retrospective analysis. Methods Charts of patients who underwent transoral robotic surgery for HPV-related oropharyngeal cancer between 2011 and 2019 were reviewed. Trend analysis was used to compare rate of adjuvant treatment over time. The Kaplan–Meier method was conducted to analyze overall survival (OS) and DFS. Results Three hundred and forty-two patients met inclusion criteria. One hundred and sixty-three (47.7%) patients underwent adjuvant radiation, and 90 (26.3%) patients underwent adjuvant chemoradiation. Rate of extranodular extension decreased significantly from 38.9% to 24.0% (P = .004). Rate of adjuvant therapy decreased significantly from 90.9% to 62.5% between 2011 and 2019 (P = .001). In patients who received adjuvant treatment, rate of adjuvant chemoradiation therapy decreased significantly from 40.0% to 20.0% (P < .0005). There was a decrease in rate of 1-year gastrostomy tube dependence in patients treated in 2015 to 2019 versus 2011 to 2014 (2.2% vs. 7.1%, P = .025). In 2011 to 2014, 2-year OS and DFS were 96% and 89%, respectively; in 2015 to 2019, 2-year OS and DFS were 96% and 94%, respectively. There was no difference in OS or DFS between the two time periods. Conclusions The rate of adjuvant therapy, particularly chemotherapy, has decreased over time. One-year gastrostomy tube dependence rate has decreased significantly from 2011 to 2014 to 2015 to 2019. There was no change in OS and DFS over this time period.

Clinical predictors of internal carotid artery blowout in patients with radiated nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader Clinical predictors of internal carotid artery blowout in patients with radiated nasopharyngeal carcinoma Via Head & Neck Abstract Background The primary objective is to identify clinical predictors of internal carotid artery (ICA) blowout in radiated nasopharyngeal carcinoma (NPC). Methods Seventeen ICA blowouts, 14 external carotid artery (ECA) bleeds, and 60 controls were identified from January 1, 2007 to July 31, 2020. Multinomial logistic regression was performed to identify features predictive of ICA blowouts. Results Headache was significantly more common among ICA blowouts than ECA bleeds and controls (58.8% vs. 7.1% vs. 6.7%, p < 0.001). The petrous skull base and sphenoid sinus lateral wall was eroded in all petrous and cavernous segment blowouts, respectively. Nasoendoscopy showing exposed clivus (OR 20.5, 95%CI 1.3–324.2) and computed tomography demonstrating skull base erosion (OR 17.8, 95%CI 1.0–311.0) were significantly associated with ICA blowouts compared to controls. Conclusions Findings of headache and skull base erosion on nasoendoscopy or imaging during NPC surveillance warrants prophylactic intervention to avoid an ICA blowout. View on the web Inoreader.

The transcriptional characteristics of mast cells derived from skin tissue in type 2 diabetes patients at the single-cell level

xlomafota13 shared this article with you from Inoreader The transcriptional characteristics of mast cells derived from skin tissue in type 2 diabetes patients at the single-cell level Via histochem Acta Histochem. 2021 Sep 21;123(7):151789. doi: 10.1016/j.acthis.2021.151789. Online ahead of print. ABSTRACT OBJECTIVES: The mechanisms underlying the role of mast cells in wound healing have not been thoroughly studied, and even fewer data are available on studies related to mast cells in the skin of patients with type 2 diabetes mellitus (T2DM). Therefore, this study aims to explore the transcriptional characteristics of mast cells at the single-cell level in patients wit h T2DM and provide experimental data for studying mast cell behaviors under abnormal glucose metabolism. METHODS: Two patients with T2DM and one trauma patient without diabetes were enrolled. Samples were derived from skin tissue resected at the time of surgery and were isolated by single cell capture technology on BD platform to prepare single cell cDNA library. Seurat was used to process raw reads and analyze data downstream of single-cell RNA sequencing, including removal of low-quality cells, identification of cell clusters at the single-cell level, and screening for differential genes with fold change > 1.5 and p < 0.05 by two-sided t-test. We performed single-cell RNA sequencing on skin tissues of T2DM patients and non-diabetics and identified the cell cluster of skin, single-cell subsets, and transcriptional characteristics of mast cells at a single-cell level. Meanwhile, gene set enrichment(GSEA) analysis was performed on the differentially expressed genes. RESULTS: A total of 8888 cells were obtained from skin tissue. Clustering analysis revealed eight-cell clusters, identified as smooth muscle cells, dendritic cells, mast cells, and T cells, respectively. Cluster 6 was identified as mast cells with the marker genes TPSAB1, CPA3, TPSB2, MS4A2,KIT, etc., which accounting for 2.7% of the total cell number.Compared with the control group, the genes highly expressed in MCs from T2DM patients, include ADH1C, PAXIP1, HAS1, ARG1, etc., and the low expression genes include PHACTR2, GGA1, RASSF2, etc. GSEA analysis suggested that the signal pathways of MCS in T2DM patients included VEGF signaling pathway, Fc gamma R-mediated phagocytosis, the B cell receptor signaling pathway, natural killer cell-mediated cytotoxicity. CONCLUSIONS: The characteristic genes of MCs in the skin tissues of T2DM patients were described at the single-cell level. These genes and enriched signaling pathways provide a theoretical basis and data support for furth er researches on dermatopathy in patients with diabetes mellitus.
