ABSTRACT
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.
ABSTRACT
INTRODUCTION: Diabetic foot ulcer (DFU) is a major cause of lower limb amputations. Many treatment recommendations have been proposed. This study was conducted to evaluate the effectiveness of topical sucralfate when combined with mupirocin ointment, in the treatment of diabetic foot ulcer in comparison to topical mupirocin alone, in terms of healing rates. METHODS: This open-labeled randomized study was conducted on 108 patients to evaluate the effectiveness of topical sucralfate and mupirocin combination, compared to topical mupirocin alone. The patients were administered the same parenteral antibiotic, and wounds were subjected to daily dressing. The healing rates (determined by the percentage reduction in wound area) in the two groups were calculated. The mean healing rates in both groups were expressed in percentage and compared using the Student's t-test. RESULTS: A total of 108 patients were included in the study. Male-to-female ratio was 3:1. The incidence of diabetic foot was the highest (50.9%) in the age group of 50-59 years. The mean age of the study population was 51 years. The incidence of diabetic foot ulcers was highest in the months of July-August (42%). A total of 71.2% patients had random blood sugar levels between 150-200 mg/dL, and 72.2% patients had diabetes for five to 10 years. The mean±standard deviation (SD) of the healing rates in the sucralfate and mupirocin combination group and the control group were 16.2±7.3% and 14.5±6.6%, respectively. Comparison of the means by Student's t-test failed to show a statistical difference in healing rates between the two groups (p=0.201). CONCLUSION: We concluded that the addition of topical sucralfate does not show any obvious benefits in terms of healing rates in diabetic foot ulcers as compared to mupirocin alone.
