Medical records were reviewed to abstract the demographic data, clinical presentation, evaluation, treatment, and follow-up outcomes. A total of 12 patients (1.4%) with myopericarditis were identified. All the patients were male, 8 (67%) of whom were Caucasian, and their median age

was 16 years (range, 11-17 years). Two of the patients buy MG-132 (17%) had recently used illicit drugs, and two (17%) had recently smoked cigarettes. At presentation, symptoms included chest pain in 12 patients (100%, 12/12), upper respiratory symptoms in 3 patients (25%, 3/12), and shortness of breath in 3 patients (25%, 3/12). No cardiac murmur or gallop was noted in any patient. Electrocardiographic (ECG) changes included diffuse ST-T changes (5 patients), localized ST-T changes (6 patients), and no ST-T changes (1 patient). All the patients had elevated levels of cardiac enzymes, with a median Troponin I level of 21.4 ng/ml (range, 5.0-134.4 ng/ml) and a median Linsitinib price CK-MB level of 50.2 ng/ml (range, 7-135 ng/ml). Echocardiography showed normal left ventricular systolic function in all the patients (median ejection fraction, 61%; range, 56-69%).

None had pericardial effusion during the first echocardiographic evaluation. Coronary angiography showed normal coronary arteries in all nine subjects for whom it was performed. Treatment of myopericarditis consisted of ibuprofen, acetaminophen, and/or aspirin. During a median follow-up period of 2 months (range, 2 weeks to 3 years), all the patients were asymptomatic with echocardiography showing normal left ventricular size and function. Myopericarditis was exclusively seen in male adolescents. Despite markedly elevated levels of cardiac enzymes, the clinical evolution of myopericarditis seems benign without any myocardial dysfunction. The inflammatory involvement of the myocardium appears to be self-limited without short-term, overt sequelae. An elevated troponin I level in myopericarditis,

unlike acute coronary syndromes, does not seem to carry an adverse find more prognosis. Further studies are needed to evaluate the long-term prognosis for such patients.”
“Liversamples from 51 cetaceans, comprising 10 species, stranded between 1994 and 2006 in a highly industrialized and urbanized region in Southeast Brazil, were analyzed for polybrominated diphenyl ethers (PBDEs) and methoxylated-PBDEs (MeC-PBDEs). A concentration range of PBDEs (3-5960 ng/g lw) similar to that observed in Northern Hemisphere dolphins was found. MeO-PBDE concentrations in continental shelf(CS) dolphins from Brazil are among the highest detected to date in cetaceans (up to 250 mu g/g lw). Higher Sigma MeO-PBDE concentrations were measured in CS and oceanic dolphins than in estuarine dolphins. The Sigma PBDE/Sigma MeO-PBDE ratio varied significantly ranging from a mean value of 7.12 to 0.08 and 0.01 for estuarine, CS and oceanic species, respectively.
