“Biliary drainage was performed in a 71-year-old man with obstructive jaundice learn more of unknown origin; however, he died due to acute pulmonary failure. At autopsy, proliferation of adenocarcinoma cells was observed in the gallbladder mucosa transitioning from isolated signet-ring cell carcinoma (SRCC) to the subserosa and bile ducts without growth toward the gallbladder lumen. Furthermore, fibrocellular intimal proliferation, tumor emboli and organized thrombi were observed in the small pulmonary arteries. The final diagnosis was gallbladder carcinoma complicated by SRCC associated pulmonary tumor thrombotic microangiopathy (PTTM). PTTM may present as rapidly progressive dyspnea, and a high level of clinical suspicion is required to make the differential diagnosis.”
“The synthesis of beta-thiolactone and beta-lactam analogs of tetrahydrolipstatin is described from a common late-stage beta-lactone derivative. These

analogs, and a cis-disubstituted beta-lactone analog of tetrahydrolipstatin, were screened for activity against porcine pancreatic lipase and for inhibition of cell growth of a panel of four human cancer lines.”
“OBJECTIVES: Muscletech Hydroxycut (Iovate Health Sciences Research, Oakville, Ontario, Canada) was a popular weight-loss supplement that was recalled find more by the manufacturer in May 2009 on the basis of reports of hepatotoxicity associated with this supplement. We sought to characterize the clinical presentation of Hydroxycut-associated liver AZD7762 injury and to adjudicate these cases for causal association with Hydroxycut.\n\nMETHODS: We assessed the causality and grading of severity of liver injury using methodology developed by the Drug-Induced Liver Injury Network (DILIN) study.\n\nRESULTS: Eight patients who developed liver injury after taking Hydroxycut treated at different medical centers were identified. All were hospitalized, and three of eight patients required liver transplantation. Nine other cases with adequate clinical information were obtained from the FDA MedWatch database, including one fatal case of acute liver failure. Usual symptoms were jaundice, fatigue,

nausea, vomiting, and abdominal pain. Most patients exhibited a hepatocellular pattern of injury. Adjudication for causality revealed eight cases as definite, five highly likely, two probable, and two were considered to be possible.\n\nCONCLUSIONS: Hydroxycut has been clearly implicated as a cause for severe liver injury that may lead to acute liver failure and death. Weight-loss supplements represent a class of dietary supplements that should be regarded as capable of causing severe hepatic toxicity when the usual causes of identified liver injury cannot be otherwise elucidated.”
“Bronchopulmonary dysplasia (BPD) is the most frequent chronic lung disease in preterm newborn infants. It is a multifactorial disease caused by the interaction between environmental and genetic factors.
