Publication Diagnostic Accuracy of Intraoperative Frozen Section in Ovarian Neoplasms: Experience in a Tertiary Oncology Centre(Kathmandu University, 2018) Bajracharya, Shakya A; Jain, V; Sekhon, R; Rawal, S; Mehta, AABSTRACT Background Ovarian cancer is the second most common type of female genital tract malignancy. Treatment planning differs for benign, borderline and malignant subtypes of surface epithelial tumours and depends on accurate histopathological diagnosis. A pre-operative diagnosis of the nature of ovarian tumors is not always reliable. Frozen section is a valuable diagnostic tool in rapid intraoperative categorization of ovarian masses and thereby helps in planning the surgical management. Adequate management and treatment of ovarian carcinoma requires a complete surgical staging supported by frozen-section examination. To achieve this goal it is necessary to have a high level of accuracy. Objective To assess the accuracy of intra-operative frozen section in the diagnosis of various categories of ovarian neoplasm conducted in Rajiv Gandhi Cancer Institute and Research Centre. Method Intra-operative frozen sections for suspected ovarian neoplasm that underwent surgery as primary line of therapy at this institution were analyzed retrospectively from Jan. 2014 - Dec. 2015. The results of frozen section were compared with the final histopathology diagnosis on paraffin sections and the overall accuracy, sensitivity, specificity, positive and negative predictive values were determined. Result The study included 159 cases and the mean age of patients was 44.72±14.28 years (Range 19-75 years). The mean size of tumor was 12.5±5.9 cm. Sensitivity of frozen section for benign, borderline and malignant tumors was 98.53%, 73.33% and 94.74% respectively and the related specificities were 95.60%, 96.53% and 100% respectively. There were 150 concordant cases and 9 discordant cases. Overall diagnostic accuracy of frozen section was 94.33%. Conclusion Intra-operative frozen section diagnosis appeared to be an accurate and comparable technique for the histopathology diagnosis of ovarian tumors.

The pain was associated with 2 episodes of fainting attacks in emergency during the period of observation. Viable intrauterine pregnancy of 8-9 weeks along with collection of fluid in the Pouch of Douglas was detected by ultrasound examination and on laparotomy ectopic pregnancy was confirmed with haemoperitoneum of 2 litres with 500gms of clots. Histopathology report confirmed the tubal ectopic pregnancy and postlaparotomy, transvaginal sonography confirmed the salvage of the intrauterine pregnancy. Despite massive haemoperitoneum, the pregnancy continued till 40+6 weeks with uneventful antenatal period. She underwent emergency caesarean section for meconium stained liquor with foetal distress and delivered of an alive healthy female of 2.5 kg with good Apgar score.

It has been implicated that patients have disorders of lipid metabolism and are involved in the pathogenesis of fatty liver. Hence, it was designed to observe the association between lipid profile and fatty liver disease. Objective This study was undertaken to evaluate the association of lipid profile status, hemoglobin and albumin levels with fatty liver disease patients diagnosed based on ultrasonography (USG). Method This Cross-sectional study was undertaken in the Department of Internal Medicine with the collaboration of the Department of Radiology and Department of Biochemistry, Universal College of Medical Sciences-Teaching Hospital (UCMS-TH), Bhairahawa, Nepal from March 2019 to February 2020 in a total of 100 patients diagnosed with fatty liver disease by ultrasonography. The fasting blood was collected for lipid profile and carried out in the automated analyzer following standard protocol. Result In 100 cases, the male to female ratio was 1.8:1. Fifty six percent of the total cases presented with alcoholic fatty liver disease (AFLD) while the remaining 44% with nonalcoholic fatty liver disease (NAFLD). The spectrum of lipid abnormality was observed with increased total cholesterol (TC), Low Density Lipoprotein (LDL), increased triglycerides (TG), Very Low Density Lipoprotein (VLDL) in alcoholic fatty liver disease cases as compared to nonalcoholic fatty liver disease cases. However, it has been observed that TG/HDL and Non-HDL/HDL were higher in nonalcoholic fatty liver disease as compared to alcoholic fatty liver disease. Moreover, a statistically significant difference was observed in HDL between AFLG2 and NAFLG2 (p-value: 0.012). Conclusion Dyslipidemia and decreased HDL have been implicated in fatty liver diseases. USG in conjunction with Non-HDL/HDL, TG/HDL, hemoglobin, and albumin can be useful in early screening and monitoring of dyslipidemia in fatty liver patients.
