paythelady.61 shared this article with you from Inoreader

Abstract

Background

Despite adjuvant radiotherapy, rates of recurrences of endoscopically operated nasal intestinal-type adenocarcinomas (ITAC) have not been improved in successive series. To better understand how to improve local control, we aimed to investigate the site of local recurrences of ITACs.

Methods

Retrospective study in a reference center in sinonasal malignancies. For all patients with a local recurrence, radiotherapy plans were retrieved and compared to the delineation of local recurrences.

Results

Of 63 patients, 54 underwent adjuvant radiotherapy of which 14 (25.9%) had a local recurrence. Eleven of them had their onset in an optimally irradiated area. Difficulty to dissect the cribriform plate and/or the lateral lamina was reported for 11 patients with local recurrences in the operative reports (p <0.0001).

Conclusions

Most of recurrences arose in an optimally irradiated area. A close cooperation between surgeons and radiotherapists is required to define areas at risk and adapt treatment.

The implicated clinical factors for outcomes in 304 patients with salivary duct carcinoma: Multi‐institutional retrospective analysis in Japan

paythelady.61 shared this article with you from Inoreader

Abstract

Background

Salivary duct carcinoma (SDC) is a high-grade salivary malignancy that frequently occurs as the carcinomatous component of carcinoma ex pleomorphic adenoma. We herein examined the clinical factors affecting outcomes in a large cohort of SDC.

Methods

We selected 304 SDC cases and investigated clinical characteristics and the factors affecting outcomes.

Results

The median age of the cases examined was 68 years, the most common primary site was the parotid gland (238 cases), and there was a male predominance (M/F = 5:1). Outcomes were significantly worse when the primary tumor site was the minor salivary glands (SG) than when it was the major SG. Outcomes were also significantly worse in pN(+) cases (161 cases) than in pN0 cases, particularly those with a metastatic lymph node number ≥11. The cumulative incidence of relapse and distant metastases was significantly higher in stage IV cases than in stage 0–III cases.

Conclusions

The absolute number of lymph node metastases, higher stages, and the minor SG as the primary tumor site were identified as factors affecting the outcome of SDC.

Otolaryngology–Head and Neck Surgery, Ahead of Print.
David McDonogh, born into chattel slavery in Louisiana in the early 1800s, accomplished the unfathomable by becoming the first Black otolaryngologist in the United States of America. With tireless determination and profound intellect, Dr McDonogh surmounted immeasurable adversity along his improbable journey to freedom and success as an eye, ear, nose, and throat doctor in New York. His doctorate in medicine was posthumously awarded to his great-great-granddaughter in 2018 by the Columbia University Vagelos College of Physicians and Surgeons. In this History of Otolaryngology piece, we share his extraordinary story.

Anatomical variations in the relationship between the spinal accessory nerve and internal jugular vein: a systematic review and meta-analysis

paythelady.61 shared this article with you from Inoreader
The relationship between the spinal accessory nerve and internal jugular vein is important for modified neck dissection surgery. Therefore, the aim of this review was to investigate variations in this relationship. Through a search of the PubMed, Scopus, Web of Science, LILACS, and SciELO databases, the review authors collected anatomical data for inclusion in a meta-analysis, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four relationship patterns were identified and classified: type 1, the nerve lies superficial to the vein; type 2, the nerve lies deep to the vein; type 3, the nerve crosses the branches of the vein; type 4, the nerve splits and its branches pass around the vein.

Fibrin immobilization vestibular extension (FIVE): A case series

paythelady.61 shared this article with you from Inoreader

Abstract

Aims

The objective of the present case series is to report on the rationale, surgical technique and outcome of a protocol for peri-implant mucosal phenotype modification therapy, referred to as "fibrin immobilization vestibular extension (FIVE)".

Material and Methods

The protocol utilized entailed apical positioning and stabilization of peri-implant flap with modular screws. The screws were also used for the immobilization of solid matrix platelet-rich fibrin to fill the gap created between apically positioned flap and the crestal margin of the flap.

Results

A total of 30 patients (12 male, 18 females) with 93 implants were treated with FIVE protocol for various indications, including for vestibular extension following alveolar ridge augmentation (N = 6), preprosthetic (N = 9), postprosthetic (N = 2), and peri-implantitis (N = 13). The keratinized mucosal width preoperatively was 1.67 mm with 95% confidence interval [CI] (1.46, 1.88). Immediately following FIVE surgery, the vestibule was extended to 9.10 with 95% CI (8.44, 9.76). At 3 months, 4.9 mm (95% CI: 4.5–5.2 mm) of peri-implant keratinized mucosal width was present. The keratinized mucosal width remained relatively stable thereafter and was 4.0 mm (95% CI: 3.5–4.5 mm) at 3 years post-FIVE surgery. When overall group means across all time points were analyzed, maxilla had mean of 6.1 mm (95% CI: 5.8–6.5) versus mandible exhibited mean of 5.1 mm (95% CI: 4.6–5.6 mm). The mean of maxilla was si gnificantly higher than that of the mandible (p < 0.0001) across all time points. Treatment of peri-implantitis with FIVE lead to significant pocket reduction and wide band of keratinized mucosa. Seven of 38 implants in 3 of 13 peri-implantitis patients were removed due to advanced peri-implantitis.

Discussion

The present case series provides proof-of-principle data for efficacy of FIVE for peri-implant phenotype modification therapy that generated attached keratinized mucosa in a variety of applications. This protocol provides an alternative to procedures involving harvesting of autogenous mucosal graft.

Ear Nose Throat J. 2022 Mar 29:1455613221086032. doi: 10.1177/01455613221086032. Online ahead of print.

ABSTRACT

Accidental swallowing of fish bone is one of the most common emergencies in the otolaryngology department. The impacted fish bones are usually found in the palatine tonsil, base of the tongue, valleculae, pyriform sinus, and esophagus, which can be successfully removed after a thorough examination. However, in some cases, the fish bone may penetrate into the neck soft tissue and migrate to extraluminal organs, causing infection, abscess formation, or rupture of vessels. In such cases, prompt recognition and immediate removal of the impacted fish bone are necessary. Herein, we report a rare case of a 60-year-old woman who had accidently swallowed a fish bone 10 days prior to visiting the outpatient department. The fiberoptic scope and head and neck computed tomography scans were obtained from the outpatient department. The fish bone was found to migrate from the upper esophagus to the left thyroid gland. First, a rigid esophageal endoscopy was performed in the operating room, but no obvious fish bone was noted over the esophagus. Finally, the fish bone was removed via exploratory cervicotomy with left-sided total lobectomy of the thyroid. The patient recovered after the operation, and there were no further complications during the 3 years of follow-up.

Improvement of performance and function in respiratory protection equipment using nanomaterials

xlomafota.13 shared this article with you from Inoreader

Abstract

Nanotechnology has become one of key areas for the current development and research. Nanotechnology focuses on matter at the nanoscale and is capable of using different approaches to produce nanomaterials, structures, devices, and systems. One of the concerns that have to be addressed is the adverse effects of exposure to pathogens and pollutants in different workplaces and environments. Respiratory protective equipment (RPE) is one of the personal protective equipment (PPE) utilized to reduce the risk of exposure to environmental or occupational respiratory hazards. Thus, various studies have been conducted for improving the functional properties of sorbents or filters in different kinds of RPE. Different categories of nanomaterials have been reported as effective agents for achieving this goal. The application of these nanomaterials in mask layers or respirators' cartridge could significantly increase the filtration efficiency, breathing comfort, and antiba cterial/antiviral properties of the masks and respirators. The present study aimed to comprehensively review the nanomaterials used in different types of face RPE with emphasis on various properties of the utilized nanomaterials. The study also aimed to show an applied perspective for future research on this important subject.
