Background: Fine-needle aspiration cytology (FNAC) is recommended as a decisive diagnostic step in the workup of patients with nodular thyroid disease. Unfortunately, FNAC can miss malignancies in smaller and deeper nodule. Ultrasound guided FNAC (US-FNAC) can reduce this error in suspicious thyroid nodule. Objectives: To find out the correlation of USG guided FNAC with postoperative histopathology in diagnosis of thyroid nodule. Methods: After obtaining clearance and approval from Institutional Review Board, all 45 patients of thyroid nodule who were admitted in the Department of Otolaryngology – Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from April 2017 to August 2018 and had fulfilled the inclusion and exclusion criteria were selected for the study. Each patient was assessed before surgery by USG guided FNAC and post operatively by histopathology. Results: In this study mean age of the respondents was 33.33 yearswith SD±10.84. Male female ration was 1:5.4. USG guided FNAC was reported by ‘The Bethesda System for Reporting Thyroid Cytopathology’ (TBS-RTC).Of the 45 specimens 2 samples were nondiagnostic or unsatisfactory (Class I), 26 samples were benign (Class II), 2 samples were showing Atypia of Undetermined Significance or Follicular lesion of Undetermined Significance (Class III), 6 were showing follicular neoplasm or suspicious for a follicular neoplasm (Class IV), 5 samples were suspicious for malignancy (Class V) and 4 samples were positive for malignancy (Class VI). On comparison of ultrasound guided FNAC with histopathology the sensitivity for correct diagnosis was 94%, specificity was 93%, positive predictive value was 88%, negative predictive value was 96% and accuracy was 93%. Pearson’s correlation coefficient was 0.85 which is very strong for positive relationship. Conclusion: USG guided FNAC is the most accurate method for diagnostic evaluation of thyroid nodules.

Background: Periodontitis is one of the most common oral diseases and is one of the widest spread chronic diseases all over the world. If a person maintains a good oral hygiene, he/she can control periodontitis easily. Periodontitis is a preventable disease. Objectives: This study was aimed to know the current pattern, the possible causes and the attitude towards periodontitis among adult patients attending at outdoor of dental faculty of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. Methodology: This cross-sectional study was carried out in the OPD of Dental faculty of BSMMU, Dhaka fromJanuary 2013 to December 2013 over a period of one year. One hundred twenty patients with any sort of dental problem were enrolled in this study. Results: The current study depicted that 68.3% of the patients were from age group of 18 to 40 years and 59.2% were male while 40.8% were female. Most of the respondents (65.8%) lived in urban area. This study showed that 80.8% experienced bleeding from gums and 59.2% had knowledge about cleaning teeth before going to bed and after breakfast. It was found that 77.5%of the respondents used tooth brush and tooth paste for cleaning their teeth. Only 15.8% of the respondents visited dentist for oral and dental check-up regularly. According to life style related habit, 53(44.2%) respondents were smoker, 55 (45.8%) respondents chewed betel leaf and 30 (25%) of the respondents hewed betel leaf with Jarda or SadaPata. Majority 104 (86.7) had calculus, defective margins and restorations. Most of the respondents (95.0%) had bleeding on probing. Conclusion: In this study a significant number of respondents have periodontitis who have attended outdoor of dental faculty. Older age, smoking, betel, jarda/sadapata, diabetes mellitus and presence of calculus and restorations are the risk factors for developing periodontitis.
