Item Incidental thyroid carcinoma in benign thyroid disease: A Cohort study(World Journal of Endocrine Surgery., 2018) Pinto, D.; Munasinghe, N.; Chandrasinghe, P.C.; Fernando, R.ABSTRACT: AIM: An incidental thyroid carcinoma (ITC) is a thyroid malignancy that is not clinically or cytologically detected preoperatively. The incidence of ITC is between 10% to 20% in the literature. A study was undertaken to assess the incidence of ITC in patients undergoing total thyroidectomy for benign disease of the thyroid to University Surgical Unit, North Colombo Teaching Hospital (NCTH), Sri Lanka. MATERIALS AND METHODS: Prospective cohort study was undertaken from November, 2002 to October, 2015. Patients with palpable thyroid nodules were assessed with fine needle aspiration cytology (FNAC) and ultrasound scan (USS) to ascertain benign thyroid disease (BTD). Hormone assays were conducted to detect thyroid status. All patients with BTD who underwent total thyroidectomy were included in the study. Histopathological assessments were made by a panel of pathologists. Patients with autoimmune thyroiditis (AIT) were excluded due to the known association with malignancy of the thyroid. Post-thyroidectomy histopathological diagnoses were collected prospectively and patients with ITC were identified. Statistical analysis was done using statistical package for the social sciences (SPSS) software, version 20. RESULTS: Hundred and sixty seven patients (n = 167) who fulfilled the inclusion criteria were analysed (Male–20, female–147, median age = 40.25 year, range 28 year–62 year). ITC was found in 19 patients with an incidence of 11.38%. No significant association was noted with morphology, biochemical status of the thyroid or gender. CONCLUSION: Incidence of ITC is 11.38% in this cohort. Incidence of ITC being approximately 1:10 emphasizes the need to consider total thyroidectomy in the management of BTD.Item A Comparative international study on the management of acute appendicitis between a developed country and a middle income country(Elsevier, 2014) Markar, S.R.; Pinto, D.; Penna, M.; Karthikesalingam, A.; Bulathsinhala, B.K.S.; Kumaran, K.; Hashemi, M.; Fernando, R.BACKGROUND: In the past decade there has been an exponential increase in the use of Computerised Tomography (CT) imaging in the assessment of patients with acute appendicitis. The aim of this study was to compare management approaches and clinical outcomes of acute appendicitis in Sri Lanka and the United Kingdom. METHODS: Data was collected prospectively from 400 patients referred to the General Surgical department with a differential diagnosis of acute appendicitis, 200 at University Kelaniya Sri Lanka (SL group), and 200 at University College London Hospital (UK group). RESULTS: The groups were similar with respect to gender, but the SL group was younger. Preoperative work-up included ultrasound more commonly in SL patients, and CT more commonly in UK patients. More patients underwent appendicectomy in the SL group, however a laparoscopic approach was utilised more often in the UK group (50.5% vs. 11.9%). Post-operative complications were similarly represented in both groups, but re-admission occurred with greater frequency in the UK group (16.2% vs. 0%). Histologically confirmed appendicitis was seen in a significantly greater proportion of SL patients (93.1% vs. 79.8%). Multivariate analysis confirmed male gender, and diagnosis and treatment in Sri Lanka to be only factors significantly associated with positive appendicitis. DISCUSSION: Expensive investigations such as CT do not appear to improve the diagnostic accuracy of appendicitis or prevent complications. This study suggests diagnostic and treatment algorithms in the SL hospital are more accurate and efficient in confirming appendicitis than those seen in the UK hospital under investigation.
