Reliability of a Tailored Tele-Medicine Model for Otorhinolaryngology-Head and Neck Surgery (ORL-HNS) Clinical Practice in Remote Areas of Nepal: A Pilot Study from Tertiary Referral Center.

Introduction: Despite the ever-expanding scope of telemedicine, studies regarding its application in the field of otorhinolaryngology-head and neck surgery (ORL-HNS) in remote parts of the world are lacking. This pilot study aims to bridge the research gap and to assess the efficacy of our tailored telemedicine clinic model, operating in an "asynchronous" mode, in diagnosing various ORL-HNS diseases. Methods: This is a cross-sectional study conducted at a tertiary care center of Nepal. An asynchronous telemedicine portal was used with a store and share approach to telecast the pen endoscopic camera findings to the consultant in order to formulate a diagnosis and a management plan. Interobserver reliability was assessed using SPSS version 26 based on Cohen's kappa. The association between the results of the Mimi Hearing App (v. 5.0) and pure tone audiometry were performed using chi-square test. Results: The overall diagnostic agreement in our study was substantial to almost perfect with kappa values of .843, .784, .737, and .764 for rhinology, head and neck, otology, and pediatric cases. Chronic otitis media was the predominant diagnosis across all age groups. Various head and neck swellings, symptomatic deviated nasal septum and chronic rhinosinusitis with polyposis followed closely. Discussion: The future of telemedicine in otorhinolaryngology can be gauged to be effective in reducing cost and human resource use in the limited setting of Nepal with the model allowing for remote but effective communication between the concerned patients and the expert doctor in clarifying doubts and making diagnosis, early recognition of diseases and preventing or decreasing complications of those diseases.

Diagnostic Accuracy of Fine Needle Aspiration Cytology as Compared to Histopathology in Parotid Gland Swelling.

BACKGROUND: The diagnosis of parotid swelling is challenging and investigations like imaging and needle aspiration cytology are helpful. The objective of this study was to determine the diagnostic accuracy of fine needle aspiration cytology (FNAC) as compared to the histopathology in parotid gland swelling. METHODS: It was a descriptive cross sectional study carried out in the Department of ENT-Head and Neck Surgery, Tribhuvan University Teaching Hospital, Institute of Medicine, Kathmandu by reviewing the medical record charts of the patients who had undergone surgery for parotid lesions during the study period of seven and half years. All patients whose fine needle aspiration cytology and histopathology reports were available were included in the study. The data were presented as mean, standard deviation, ratio and percentages. Microsoft excel was used for data analysis. RESULTS: There were 75 patients included in the study. The age ranged from nine years to 78 years and the mean age being 38.3 17.42 years. The male to female ratio was 1:1.78. The concordance rate between fine needle aspiration cytology and histopathology was 82.7%. The sensitivity and specificity of the fine needle aspiration cytology were 80% and 95% respectively. Similarly, the positive predictive and negative predictive values were 84% and 93% respectively. The diagnostic accuracy of the fine needle aspiration cytology was 91% for the parotid swelling in our study. CONCLUSIONS: The diagnostic accuracy of fine needle aspiration cytology for parotid swellings in our study was excellent. The result of fine needle aspiration cytology is helpful in deciding management plan for parotid lesions.

Aspiration of a Row of Artificial Dentures in an Adult: A Case Report.

Clinical findings of foreign body aspiration, generally, are subtle. Scrutinous clinical suspicion is always recommended. Here, we present a rare case of an adult male, who under the influence of alcohol had aspirated a row of his artificial denture without his conscience of where his denture got missing and presented to our outpatient department with non-specific symptoms. With clinical examination and advanced diagnostics, he was successfully managed with rigid bronchoscopy. With the advancement in diagnostic techniques and our widened knowledge of the condition, utmost early detection has been possible and our case report reinforces the need for a low threshold for foreign body aspiration suspicion, especially in adults with dentures, and the use of rigid bronchoscopy as a plausible tool for the prompt management of the aspiration. Keywords: bronchoscopy; case reports; dentures; foreign bodies.

The Bethesda System for Reporting Thyroid Cytopathology: Validating at Tribhuvan University Teaching Hospital

Abstract Introduction Fine needle aspiration cytopathology (FNAC) is widely used for the stratification of thyroid nodules. Objective The objective of the present study is to validate FNAC reporting based on The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) at our institution and to calculate the risk of malignancy in each category. Methods This was a descriptive cross-sectional study conducted jointly at the Department of Ear, Nose and Throat and at the Department of Pathology for a period of 1.5 years (May 2018 to November 2018). All cases presenting with thyroid swelling in the outpatient department were investigated with ultrasonography (USG) of the neck, thyroid function test, and FNAC. All FNAC reporting was done according to TBSRTC. Results A total of 134 thyroidectomies were performed during the study period. The female to male ratio was 5.3:1. The age ranged from 11 to 74 years old. with a mean age of 51 years old. The FNAC has a specificity of 84.9%, a sensitivity of 89.4%, a positive predictive value of 86.4%, a negative predictive value of 88.2%, and an accuracy of 87.3% in detecting thyroid cancer. The implied risk of malignancy (ROM) in Bethesda II, III, IV, V and VI is 11.7%, 25%,40%,76.6% & 96%, respectively. Conclusion The four studied categories had a ROM comparable to other studies, except for the Bethesda III category. Further studies with larger sample sizes and with the use of USG guidance for the aspiration from the thyroid swelling may give better results by reducing the number of false negative and false positive cases.

Prevalence of Post Tonsillectomy Haemorrhage at a Tertiary Care Centre in Nepal.

INTRODUCTION: Tonsillectomy is one of the common ENT surgical procedures. Post-tonsillectomy haemorrhage remains a frequent complication which can be potentially life-threatening. The objective of the present study was to calculate the prevalence of haemorrhage following a tonsillectomy at a tertiary care centre. METHODS: It was a descriptive cross-sectional study performed by medical chart review of the patients who underwent tonsillectomy from January 2018 to December 2019 at the department of ENT- Head and Neck Surgery of Tribhuvan University Teaching Hospital. Ethical approval was obtained from the institutional review committee (Ref:-282(6-11) E2 076/077). Convenient sampling method was used. All patients of any age who had tonsillectomy for recurrent tonsillitis or tonsillar hypertrophy with or without obstructive sleep apnoea and no missing information on chart review were included in the study. Data were entered in MS-Excel 2007 and analyzed in rate and percentage. RESULTS: Ten (5.18%) out of a total of 193 patients who underwent tonsillectomy had a post tonsillectomy haemorrhage. All 10 (100%) were adults patients, operated for recurrent tonsillitis, and used electrocautery. It was common in male patients 7 (70%). All of the haemorrhages was between a third and sixth postoperative day and were mild in severity. CONCLUSIONS: The prevalence of post-tonsillectomy haemorrhage was high at our centre during the study period of two years. It was common in adults, males and surgery done for recurrent tonsillitis using electrocauterization.

Prevalence of p-16 Positive Laryngeal and Pharyngeal Tumors in Nepalese Population: A Hospital based Cross-sectional Study.

INTRODUCTION: P16 overexpression is considered as a good prognostic marker for oropharyngeal squamous cell carcinoma. However, there are very few literatures on the prevalence and outcomes of p16 overexpression in non-oropharyngeal squamous cell carcinoma and benign head and neck tumors. The aim of our study was to estimate the hospital based prevalence of p16 positive laryngeal and pharyngeal tumors and to compare it with the prevalence of p16 expression in the non tumor tissue (tonsils). METHODS: This was a descriptive cross-sectional study. Cases of all genders >15 years presenting with malignant or benign tumors of larynx and all the subsites of pharynx were included in the study for evaluation of p16 expression by immunohistochemistry. Tonsillar tissue of cases undergoing tonsillectomy for recurrent acute tonsillitis were taken as non-tumorous tissue to evaluate for p16 expression. RESULTS: A total of 48 cases were included in our study with 24 cases having different tumors of head and neck region and 24 cases having recurrent acute tonsillitis who were kept under non-tumor group. Eight cases (33.3%) in the tumor group showed positive stain for p16 in IHC. In non tumor group, 7 cases (29.1%) showed positive IHC staining for p16. CONCLUSIONS: P16 expression can be present in both benign and malignant tumors of various subsites of head and neck region and also in tonsillar tissue affected by inflammation.

Rigid Bronchoscopy in Airway Foreign Bodies: Value of the Clinical and Radiological Signs

Abstract Introduction Foreign body in airway is a common emergency in ENT practice. As we know, Rigid Bronchoscopy is the method of choice for removing it, although at times it leads to specialists performing unnecessary bronchoscopy, exposing patients to hazards of general anesthesia. Objective The objective of my study is to calculate sensitivity, specificity, positive predictive value, odds ratio from the clinical and radiological signs, comparing with the gold standard, the rigid bronchoscope procedure. Method This is a prospective analytical study designed at University Teaching Hospital and conducted over a period of 18 months, from March 2011 to August 2012. Data collection was broadly classified into three different categories: (1) Symptomatology, such as presence or absence of choking, cyanosis, and difficulty in breathing; (2) Clinical signs, such as the presence or absence of air entry, crackles, and rhonchi 3. Chest X-ray findings were suggestive of a foreign body. Results There were a total of 40 rigid bronchoscopies performed under general anesthesia for the diagnosis and therapeutic reasons. Among 40 patients who underwent rigid bronchoscopy, 32 (80%) were found to have varieties of foreign bodies in their airway while 8 patients (20%) had negative bronchoscopy. The history of choking is the only clinical symptoms which came out to be statistically Significant (p = 0.043) with odds ratio of 5. Conclusion Rigid bronchoscopy is the gold standard technique for diagnosis and procedure of choice to remove FB from airway. Regardless, it still presents a small chance of negative result, especially when there is no history of aspiration. received.
