RESUMO
Background and Aims: This study examines the relationships between epicardial adipose tissue (EAT), nonalcoholic fatty liver disease (NAFLD), and coronary artery calcium score (CACS) using non-ECG-gated CT scans. It aims to determine the effectiveness of EAT measurements and NAFLD as predictors for coronary artery disease (CAD). Methods: This cross-sectional study was conducted at a specialized center, focusing on individuals who underwent non-ECG-gated chest CT scans without contrast. We evaluated EAT thickness and density in three areas: the right atrioventricular groove, the free wall of the right ventricle, and the central area of the right anterior interventricular groove. Additionally, we measured CACS and determined the presence of NAFLD by comparing liver-to-spleen density ratios. Statistical analyses, including regression models, were performed using SPSS (version 26). Results: In this study, we enrolled 365 participants, including 203 males with an average age of 47 ± 17.93 years. EAT thickness was 6.28 ± 1.62 mm, and EAT density was -96.07 ± 12.47 Hounsfield units (HU). The mean CACS was 22.27 ± 79.01, and the mean liver density was 50.01 ± 10.76 HU. A significant positive correlation was observed between EAT thickness and CACS (r = 0.208, p < 0.001). EAT density showed a significant negative correlation with CACS (r = -0.155, p = 0.003). No correlation was found between NAFLD and CACS. Univariate logistic regression analysis identified significant predictors of increased CACS, including EAT thickness (OR: 1.803), EAT density (OR: 0.671), diabetes mellitus (DM) (OR: 5.921), and hypertension (HTN) (OR: 7.414). Multivariate analysis confirmed the significance of EAT thickness (OR: 0.682), DM (OR: 3.66), and HTN (OR: 2.79) as predictors of elevated CACS. Conclusion: Our findings demonstrate that increased EAT thickness and decreased density are associated with higher CACS. Also, both DM and HTN significantly contribute to increased CACS. These results support the inclusion of EAT measurements in cardiovascular risk assessment models to enhance diagnostic accuracy.
RESUMO
INTRODUCTION: Myelolipoma, a benign tumor characterized by mature fat cells and hematopoietic cells, is predominantly found in the adrenal glands, accounting for 6-16 % of all adrenal tumors. These tumors are often asymptomatic and discovered incidentally during imaging. We present a rare case of concurrent adrenal and extra-adrenal myelolipomas, contributing to the limited research in this area. CASE PRESENTATION: A 65-year-old female with a history of Steven-Johnson syndrome presented with epigastric pain, initially diagnosed with emphysematous cholecystitis. Imaging revealed unexpected lesions near the left kidney. During surgery for presumed cholecystitis, significant hemorrhaging occurred following an attempted biopsy of the left adrenal lesion. This complication necessitated a complete adrenalectomy. Pathological examination confirmed the presence of myelolipomas in the left adrenal gland, para-aortic, and left para-iliac regions. DISCUSSION: The simultaneous occurrence of adrenal and extra-adrenal myelolipomas is exceptionally rare, posing diagnostic and management challenges. This case highlights the complexity of managing patients with multiple comorbidities and the critical importance of differentiating myelolipomas from other fat-containing retroperitoneal masses. The incidental discovery of these tumors and their potential for significant intraoperative complications, as seen in our case, underscores the need for careful surgical planning and thorough preoperative assessment. CONCLUSION: This case emphasizes the diagnostic challenges and management complexities in patients with incidental findings of myelolipoma, particularly when accompanied by significant medical histories. The occurrence of unexpected intraoperative complications highlights the importance of cautious decision-making in surgical interventions. This report provides valuable insights into the unpredictable nature of medical practice and the management of rare pathologies.
RESUMO
Biloma refers to the encapsulated accumulation of bile in the abdomen. Bilomas generally occur after bile duct disruption. The clinical case of the present report was a 75 Y/O woman with jaundice, fever, abdominal pain, lethargy, and anorexia who had been admitted to the emergency department. Endoscopic retrograde cholangiopancreatography (ERCP) showed severe diffuse dilation of the common bile duct (CBD) and common hepatic duct (CHD) with filling defects. One stone and some sludge and pus were extracted after balloon swiping. Plastic CBD stent placement was performed. An abdominal ultrasound scan showed a stone in the CBD and fluid collection in the right perirenal space. Under ultrasound guidance, a drainage tube was inserted into the retroperitoneal biloma. A serial ultrasound scan revealed a gradual decrease in the size of the biloma. Perforation of the bile duct, which is characterised by the collection of retroperitoneal fluid, is considered an extremely rare condition that can be fatal. Ultrasonography, computed tomography, and endoscopic retrograde cholangiopancreatography were used for the diagnosis. The treatment includes prevention of leakage and bile drainage.
RESUMO
Psoas tuberculosis abscess is very rarely detected primarily without an adjacent vertebral cold abscess. Early diagnosis prevents unnecessary operations and life-threatening complications.
RESUMO
Chondrosarcoma of the cranium is a rare malignancy. The result of treatment is challenging to assess because the slow-growing rate means that there is a long interval previously discovering the recurrence and last long time to diagnosis of recurrence. This report describes a 38-year-old man who presented with a generalized seizure 2 months before his referral. The patient underwent excisional surgery. The histological examinations revealed a cartilage developing tumor compatible with chondrosarcoma. The radiologic and histologic correlation established the diagnosis. But, the patient had two episodes of recurrence after surgery. We determined that intracranial chondrosarcoma must be comprised in the differential diagnosis of a mass with calcification on cranial imaging. Accurate diagnosis is obligatory for supplementary patient managing, and a recurrence is more common in patients only treated by surgery.
RESUMO
PURPOSE: To report the characteristics and laboratory findings of 182 patients with bacterial keratitis diagnosed at Farabi Eye Hospital in Tehran, Iran. MATERIALS AND METHODS: In this retrospective study, data were collected on demographics, risk factors, location, size and depth of the ulcer, height of the hypopyon, uncorrected visual acuity, results of smear and culture tests, and antibiotic sensitivity of cultured bacteria. RESULTS: There were 110 (60.4%) males and 72 (39.6%) females with an average age of 56.0 ± 2.3 years. Ocular trauma (17.6%) and positive history of corneal surgery (14.3%) were major risk factors. The mean age of contact lens users was 22.5 ± 7.7 years. Sixty patients (33%) used topical antibiotics, 21 (11.5%) patients utilized topical steroid, and 26 (14.3%) cases used both topical antibiotic and steroid at presentation. Culture results were, 81 (44.5%) cases were Gram-positive, 63 (34.6%) were Gram-negative, 10 (5.5%) were mixed bacteria and in 28 (15.4%) cases had detected growth. The isolated bacterial species from the corneal ulcers were less resistant to ceftazidime (6%) and amikacin (6%). The majority of patients were treated with medical therapy; however, 81 cases (44.5%) received at least one surgical procedure. CONCLUSION: Among the patients with bacterial corneal ulcers, trauma was the most common risk factor. Over-the-counter antibiotic and steroid were commonly used in the majority of patients. The most common bacteria isolated were Gram-positives, and they were less resistant to ceftazidime and amikacin. Penetrating keratoplasty was the most common surgical procedure in patient who required surgery.
