How useful is GLUT-1 in differentiating mesothelial hyperplasia and fibrosing pleuritis from epithelioid and sarcomatoid mesotheliomas? An international collaborative study.

Objective: Mesothelial hyperplasia (MH) and fibrosing pleuritis (FP) can be difficult to distinguish from epithelioid (MM-E) and sarcomatoid (MM-S) malignant pleural mesotheliomas. GLUT-1 has shown variable results regarding its sensitivity and specificity when used to evaluate mesothelial proliferations. We evaluated the utility of GLUT-1 immunostaining in differentiating MH and FP from MM-E and MM-S.

Ectopic pancreas presenting with pancreatitis and a mesenteric mass.

Ectopic pancreas is defined by the presence of abnormally situated pancreatic tissue that lacks contact with normal pancreas and possesses its own duct system and vascular supply. Ectopic pancreas in the gastrointestinal tract is not uncommon. Moreover, there are several reported cases of adult ectopic pancreatitis in the literature, but to date, only two cases of pediatric ectopic pancreatitis have been reported.

Nucleometric study of anisonucleosis, diabetes and oxidative damage in liver biopsies of orthotopic liver transplant recipients with chronic hepatitis C virus infection.

Anisonucleosis is defined as a morphological manifestation of nuclear injury characterized by variation in the size of the cell nuclei. It has been described in variety of benign conditions and is most pronounced in dysplasia and malignancy. To better understand the pathogenesis of anisonucleosis in liver diseases, this study focused on hepatocyte anisonucleosis in biopsies of liver transplant recipients who developed recurrent chronic hepatitis C virus (HCV) infection.

Familial childhood monosomy 7 and associated myelodysplasia.

Familial monosomy 7 is defined as bone marrow monosomy 7 occurring as a sole cytogenetic abnormality affecting 2 or more siblings. It manifests usually in childhood with neurologic disorder (cerebellar ataxia or atrophy) and/or hematologic disorder (marrow hypoplasia, myelodysplasia, acute myeloid leukemia, or pancytopenia). Partial or complete monosomy 7 with hematologic disorder has been reported in 13 families/pedigrees to date.

Safety of high volume lipid emulsion infusion: a first approximation of LD50 in rats.

Background: Lipid infusion reverses systemic local anesthetic toxicity. The acceptable upper limit for lipid administration is unknown and has direct bearing on clinical management. We hypothesize that high volumes of lipid could have undesirable effects and sought to identify the dose required to kill 50% of the animals (LD(50)) of large volume lipid administration.

A rare case of lipoprotein glomerulopathy in a white man: an emerging entity in Asia, rare in the white population.

Lipoprotein glomerulopathy is a rare entity that predominantly affects the Asian population, mainly the Japanese and Chinese. Lipoprotein glomerulopathy is clinically characterized by proteinuria and progression to renal failure and is caused by glomerular lipoprotein thrombi formation in association with increased levels of serum apolipoprotein E. The disease has a male predominance and can affect virtually any age group.

Lactobacillus acidophilus stimulates the expression of SLC26A3 via a transcriptional mechanism.

Clinical efficacy of probiotics in treating various forms of diarrhea has been clearly established. However, mechanisms underlying antidiarrheal effects of probiotics are not completely defined. Diarrhea is caused either by decreased absorption or increased secretion of electrolytes and solutes in the intestine.
