It is seldom tough to diagnose them prior to surgical exploration, and it is often clinically confused with close differentials. An early diagnosis based on pertinent clinical features and focused radiological findings can be pivotal in optimal management and help prevent recurrence and avoid unnecessary investigations/interventions. Objective To review articles that discuss SGF and provide vital etiological, clinical, and imaging features of this rare entity that can aid in early clinical diagnosis. Data synthesis An extensive review involving PubMed and Google Scholar and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Conclusion Submandibular gland fistula is a rare entity. It can be confused with close differentials, including branchial fistulas, if not thoroughly examined. Discharge from fistulae along with submandibular pain/tenderness and/or swelling are important diagnostic clues. A history of trauma, nodule at the site of discharge, prior submandibular disease/calculi, or discharge aggravated with food further increases a clinical suspicion. Optimal radiological investigation looking for calculi/foreign body and delineating the fistula tract is vital to affirm a diagnosis. Gland with fistula excision is a commonly advocated treatment of choice with no reports of recurrence, although conservative management and gland preserving surgery have also reported a favorable prognosis.","PeriodicalId":13731,"journal":{"name":"International Archives of Otorhinolaryngology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135304423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] = 3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis (p = 0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.","PeriodicalId":13731,"journal":{"name":"International Archives of Otorhinolaryngology","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134944440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results Primary care physicians showed limited knowledge of hearing loss in areas such as early identification and intervention, professionals responsible for hearing assessments, and hearing tests used for assessing hearing sensitivity. However, the responses also showed positive attitudes toward hearing loss. Significant associations between knowledge of and attitudes toward hearing loss were obtained regarding the type of physician, length of practice, and department posted in.

Methods we designed a retrospective cohort study and reviewed the medical records of patients operated on due to DNI from June 2016 to December 2017 at our institution. One cohort included patients treated with an intraoperative irrigation method that exerts low pressure over the irrigated tissue, and the other cohort, to a system capable of generating higher pressure. The Pearson Chi-squared test was used to analyze the data. Results A total of 42 patients whose ages ranged from 16 months to 72 years were included.

To assess the utility of different laboratory techniques for confirmation of fungal infections. To assess the strengths and limitations of the diagnostic methods.

Conclusion Aggressive treatment methods, administration of immune suppressants, and antibiotics, with an intention to salvage, have made patients susceptible to the benign fungus, causing it to evade the host immunity, thus leading to invasive infections.

He age of the patients in the studies ranged from 15 to 88 years (mean age at diagnosis: 55.6 years).
