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

 Fine needle aspiration cytopathology (FNAC) is widely used for the stratification of thyroid nodules.  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.  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.

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).

Sinus histiocytosis with massive lymphadenopathy (rosai-dorfman disease): a case report and literature review.

Introduction Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder of unknown etiology. Usually it presents with massive painless cervical lymph node enlargement. Histologically, it shows proliferation of distinctive histiocytic cells that demonstrate emperipolesis in the background of a mixed inflammatory infiltrates.

Foreign body pyriform sinus: an unusual presentation.

This is a case report of a foreign body (chicken bone) on the left pyriform sinus impacted in its lateral wall. Although it could be seen on x-ray soft tissue neck lateral view and on CT scan of the neck, the foreign body could not be found by rigid oesophagoscopy which was done twice. It was detected and removed by lateral pharyngotomy under GA.

Kikuchi-Fujimoto disease: a rare cause of cervical lymphadenopathy.

Kikuchi-Fujimoto Disease (KFD) is a self-limiting, necrotizing, histiocytic lymphadenitis (NHL) of unknown etiopathogenesis. So far in Nepal not a single case of this disease in the cervical region leading to progressive inspiratory stridor has been reported till date. Here a case of 26 years old Nepalese house wife suffering from this disease, which is histopathologically proved as KFD with complete recovery is presented.

Frequency and effective treatment of ulcers and sinuses in cases of tuberculous cervical lymphadenitis.

Objective: To investigate the frequency and effective treatment of ulcers and sinuses in cases of tuberculous cervical lymphadenitis (TCL).

Design: Observational cross-sectional study.

Place And Duration Of Study: Department of ENT, Head and Neck Surgery of Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal, during the period of two years from March, 2000 to February, 2002.

Outcome of surgical management of laryngeal carcinoma: a 5-year experience.

Objective: To investigate the outcome of surgically managed laryngeal carcinoma patients attending an outpatient clinic over a 5-year period.

Material And Methods: This was an analytical, retrospective, cross-sectional study. A total of 36 laryngeal carcinoma patients who were managed surgically with or without radiotherapy were analyzed.

Distribution of lymph nodes in the neck in cases of tuberculous cervical lymphadenitis.

Objective: To investigate the distribution of lymph nodes in the neck during the process of development of tuberculous cervical lymphadenitis (TCL) in patients attending an outpatient clinic over a 1-year period.

Material And Methods: This was a prospective, cross-sectional, observational study which included 100 cases of histopathologically confirmed TCL of >6 weeks duration.

Results: Lymph nodes in the posterior triangle (PT) were found to be commonest (51%), followed by those in the upper deep cervical (UDC; 48%) and submandibular (SM; 36%) regions.
