A rare case of foreign body aspiration presenting as subglottic stenosis: A case report.

In rare cases, foreign body aspiration may present with similar clinical features and CT findings to subglottic stenosis. A high index of suspicion and additional diagnostic techniques may be required to distinguish them.

Accuracy of Frozen Section with Histopathological Report in an Institute.

INTRODUCTION: Frozen section helps in rapid intra-operative diagnosis. It is commonly used during surgical procedures to detect malignancy so that modifications of surgery can be decided at the time of surgery on the table. Frozen section is also performed for evaluation of surgical margins and detection of lymph node metastasis. In addition it is applied for detection of unknown pathological processes.The objective of this study was to assess the accuracy of frozen section diagnosis in comparison to gold standard histopathological diagnosis and to find concordance and discordance rate of frozen section with histopathological report. METHODS: This was a cross sectional study of 41 frozen section samples done in the department of pathology of BP Koirala Institute of Health Sciences from September 2014 to August 2015. All frozen section samples with their permanent tissue samples sent for final histopathological evaluation were included in the study. RESULTS: The overall accuracy of frozen section diagnosis was 97%. The sensitivity was 94%, specificity was 87%, positive predictive value was 90% and negative predictive value was 93%. The concordance rate was 90.2% and the discordance rate was 9.8%. CONCLUSIONS: The results of frozen section varied in different organ systems and the common cause of discrepancy in our study were the gross sampling error and the interpretational error.

Clinicopathological features and complications of thyroid operations: a single centre experience.

Thyroid surgery evolution is important with a lots of hurdles faced by many surgeons to reach the present stage. The complications from the olden days reduced with improvement in understanding the disease process, development of antibiotics, anaesthesia and now restricted mainly to hypoparathyroidism and recurrent laryngeal nerve injuries. A retrospective analysis of thyroid surgeries performed at BP Koirala Institute of Health Sciences centre from 2007 to 2011 Clinicopathological features and complications were analyzed. Among 203 patients who underwent surgery for thyroid operations, 53 were malignant and 150 were benign cases. Hemithyroidectomy was the most common procedure performed (118 cases). Papillary thyroid cancer was the most common malignant lesion and colloid goiter the most common benign lesion. Postoperative complications occurred in 12 patients-infection in two patients, bleeding requiring reexploration in one patient, hypocalcemia in 6 (5-transient and 1-permanent) and hoarseness of voice in three patients (2-temporary and 1-permanent). FNAC is an easy, cost effective, reliable investigation in experienced hands. Reoperation, primary stage of the tumor and central node dissection are associated with increased complication rates.
