RESUMO
BACKGROUND: Thyroid nodules are a common clinical challenge, with a significant proportion being cancerous. Fine-needle aspiration cytology (FNAC) is widely used for diagnosis but has limitations. Ultrasound has emerged as a promising tool for distinguishing between benign and malignant nodules. This study aims to compare the diagnostic accuracy of ultrasonography (USG) and FNAC in diagnosing malignant thyroid swelling using postoperative histopathological examinations as the gold standard. METHOD: A diagnostic accuracy study was conducted over 1.5 years at Rajendra Institute of Medical Sciences, Ranchi, India. A total of 132 patients with thyroid swellings were included. Patients underwent USG and FNAC, and 99 patients subsequently underwent surgery and histopathological examination. Statistical analysis was performed to evaluate the performance of USG and FNAC, including sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV). RESULTS: The study encompassed 132 patients, predominantly 94 (71.21%) females. Most patients, i.e., 76 out of 132 (57.58%), were aged 30-50 years, with an average age of presentation at 41 years. Socioeconomic status revealed 120 (90.9%) belonging to Classes II and III. USG and FNAC exhibited sensitivities of 77.4% and 90.3%, specificities of 94.1% and 98.5%, and accuracies of 88.9% and 96.0%, respectively. FNAC demonstrated superior diagnostic performance metrics compared to USG, with higher PPV and NPV, indicating its stronger ability to correctly identify true-positive cases. Ultrasound features and FNAC findings showed significant associations with biopsy results, reaffirming their utility in diagnosing thyroid nodules. CONCLUSION: FNAC emerged as a highly accurate diagnostic tool for distinguishing between benign and malignant thyroid nodules, outperforming USG. Understanding demographic and clinical characteristics can aid in the timely diagnosis and management of thyroid disorders. Further research is warranted to enhance diagnostic algorithms and optimize patient care in resource-constrained settings.
RESUMO
INTRODUCTION: The adolescent age group typically ranges from 10 to 19 years. This age group differs from the paediatric and adult populations based on their physiological, psychological, and social behaviour. Patients of this age group usually present with trauma, swellings, burns, hernias, hydroceles, haemorrhoids, fibroadenomas, abscesses, pilonidal diseases, etc. The objective of this study was to identify various causes requiring surgical intervention in adolescent patients and to determine the demography of these patients, reasons for surgery, and surgical outcomes in the patients of the adolescent age group. MATERIALS AND METHODS: This single-centre, hospital record-based, retrospective, cross-sectional study was conducted on 445 adolescent patients who underwent various general surgical interventions from August 2022 to July 2023 in the Department of General Surgery, Rajendra Institute of Medical Sciences (RIMS), Ranchi. RESULTS: A total of 445 patients were included in this study; among them, 277 underwent elective surgeries and 168 emergency surgeries. Major surgeries included 315 patients, while 130 were daycare procedures. Males were 294, and 151 were females. Cyst excision was the most performed, followed by fibroadenoma excision. Burn (10.78%) was the most common cause requiring major intervention, followed by intestinal obstruction (6.96%) and perforation (6.51%). Mortality was observed in 6.51% of patients. CONCLUSION: In this study, the adolescent age group required more elective surgical care as compared to emergency care. Among major surgeries, abdominal laparotomy was most common, and in daycare procedures as well as overall, cyst excision was most performed.
