Lung uptake of technetium 99m sestamibi: relation to clinical, exercise, hemodynamic, and left ventricular function variables.
BACKGROUND: Technetium 99m sestamibi (2-methoxyisobutyl isonitrile [MIBI]) is a relatively new radiopharmaceutical with improved imaging characteristics for exercise myocardial perfusion studies compared with thallium 201. Although increased lung uptake of 201Tl has been shown to have important clinical significance, reflecting severity of coronary artery disease and left ventricular function, the factors affecting MIBI lung uptake are unknown. Therefore we examined the potential clinical, exercise, hemodynamic, myocardial perfusion, and ventricular function determinants of lung uptake of MIBI on exercise myocardial perfusion studies. METHODS AND RESULTS: The study cohort consisted of 103 patients referred for evaluation of coronary artery disease with exercise MIBI myocardial perfusion imaging. All patients underwent both a standard 1-day rest-stress MIBI planar imaging protocol and rest echocardiography. With the anterior-view stress images obtained 1 hour after MIBI injection, regions of interest were drawn over peak lung and myocardial activities and a lung/heart ratio was calculated. Multivariate regression analysis was used to relate the lung/heart ratio to clinical, exercise and hemodynamic, myocardial perfusion, and echocardiographic left ventricular function scores. We found no significant relation between lung/heart ratio and any patient variable. CONCLUSIONS: Unlike 201Tl, lung uptake of MIBI is not related to indexes of exercise, left ventricular dysfunction, or perfusion abnormalities. Thus MIBI lung uptake does not appear to have the same clinical significance as 201Tl lung uptake.

Gallstone disease in a rural Bangladeshi community.
BACKGROUND: The prevalence of gallstone disease (GSD) in Bangladesh is not known. We evaluated the prevalence of GSD and its relation with certain factors in a rural community in Bangladesh. METHODS: A total of 1332 persons aged 15 years and above from two villages were invited to participate in the study; 1,058 (80%) subjects responded after three invitations. Each subject answered a questionnaire, including demographic features, and underwent an upper abdominal ultrasound examination. RESULTS: GSD (current cholelithiasis and history of cholecystectomy) was detected in 5.4% of subjects. The prevalence was higher in women (7.7%) than in men (3.3%; p=0.002) The prevalence rates increased from 0.9% to 10% (p=0.0124) from those aged <30 years to those >50 years. A larger proportion of obese subjects (25/52; 48.1%) had GSD than non-obese subjects (32/1006; 3.2%). Prevalence in low, middle and high socio-economic classes was 1.5%, 5.7% and 13.4%, respectively (p=0.000). A majority (71.9%) of subjects with GSD were asymptomatic. CONCLUSION: Approximately 5% of the Bangladeshi rural community evaluated have GSD. Higher age, female gender, presence of obesity and higher socio-economic class were associated with higher prevalence of GSD.
