ABSTRACT
Objective: To evaluate the diagnostic assessment of enlarged lymph nodes, based on its perfusion pattern by taking tissue diagnosis as gold standard
Study Design: Analytical study
Place and Duration of Study: Departments of Radiology and Pathology, PIMS Hospital, Islamabad, from February to May 2016
Methodology: Color sonography of patients with clinically, palpable cervical lymph nodes were carried by senior trainee under the supervision of senior radiologist. Ultrasound guided tissue diagnosis was obtained in all suspected malignant cases. Histopathology was taken as the gold standard for determining accuracy
Results: Accuracy, sensitivity and specificity, positive and negative predictive values of color Doppler ultrasound in detecting malignant cervical lymphadenopathy was found to be 88.46%, 86.05%, 79.31% and 92.50%, respectively with diagnostic accuracy of 86.95%, when intranodal vascular pattern on color Doppler imaging was analyzed. Using spectral wave indexes, the same values were 92.31%, 90.70%, 85.71%, 95.12%, respectively with overall diagnostic accuracy of 91.30%
Conclusion: Color Doppler sonography is much sensitive borderline than grey scale findings alone. Furthermore, lymph nodes appearing in the detection of malignant nodes on grey scale images can be reliably diagnosed on Doppler scan
ABSTRACT
Objectives: To assess the incidence of NAFLD and biochemical profile in nondiabetic and diabetic patients. Study Design: It was a cross sectional descriptive study. Setting: Shalamar Institute of Health Sciences [SIHS], Lahore. Period: Six months, Jan 2015 to Jun 2015
Methods: The patients coming to the Radiology Department for abdominal ultrasound were age and sex matched into fatty liver and non-fatty liver groups and diabetic and nondiabetic groups and were further evaluated on the basis of glucose, alanine aminotransferase [ALT] and triglycerides [TG] levels from the laboratory data
Results: The findings of all biochemical parameters were raised in diabetic patients with fatty liver as well as in non-fatty liver diabetic group and the differences were found to be statistically [P value less than 0.05] significant. In non-diabetic group, out of 200 subjects 56.5% had NAFLD whereas 43.5% had no NAFLD. In diabetic patients, out of 200 patients 69% had NAFLD and 31% had no NAFLD and the difference was significant statistically [P=<0.05]. The prevalence of NAFLD 12.5% was higher in type-2 diabetic patients as compared to non-diabetic group. In non-diabetic group, 113 subjects had TG value of 181 +/- 82.49, while 87 subjects had TG of 141 +/- 44.5. In diabetic patients, 138 patients had TG value of 467 +/- 277.64 whereas 62 patients had TG value of 178 +/- 46.52, which was statistically significant [P=<0.05]
Conclusion: Fatty liver is an important marker for metabolic syndrome which is a pre-diabetic condition. The occurrence of NAFLD was elevated in type II patients of diabetes. The traditional risk factors for NAFLD are considered to be female sex, type II diabetes mellitus, obesity and hypertriglyceridemia. Hyperglycemia, hypertriglyceridemia and elevated ALT were observed more repeatedly in fatty liver than in non-fatty liver [type II] diabetic patients
