Lung volume reduction followed by lung transplantation-considerations on selection criteria and outcome.

Lung transplantation (LuTX) and lung volume reduction (LVR), either surgical (LVRS: lung volume reduction surgery) or endoscopic (ELVR: endoscopic lung volume reduction), are established therapies in the treatment of end-stage chronic obstructive pulmonary disease (COPD) patients. Careful patient selection is crucial for each intervention. If these techniques are sequentially applied there is a paucity of available data and individual center experiences vary depending on details in selection criteria and operative technique.

Thyrotropin receptor autoantibodies are independent risk factors for Graves' ophthalmopathy and help to predict severity and outcome of the disease.

Objective: The objective of this study was to examine whether TSH-receptor antibody [TSH binding inhibitory antibodies (TBII)] levels are associated with the severity of Graves' ophthalmopathy (GO) over the entire course of the disease.

Methods And Patients: A total of 159 patients with GO were followed for 12-24 months. One year after the first symptoms of GO, all patients were classified into mild or severe GO according to their clinical manifestations.

Variation of biological responses to different respirable quartz flours determined by a vector model.

Background: The hypothesis of widely differing lung damage due to commonly used types of quartz was studied in 16 samples of respirable quartzes (> 99% silica) from sites of the European quartz industry, using an in vitro test, the vector model. Two samples with high and 2 with low biological activities were identified and subsequently examined for their in vivo lung toxicity (inflammation, fibrosis, genotoxicity) and surface characteristics. Alveolar macrophages (AM) are considered the target cells of primary dust effects.

Persistently altered visceral perception after resection of an esophageal granular cell myoblastoma: a therapeutic concept revisited.

Granular cell tumors (GCTs) are rare and usually benign gastrointestinal tumors. Their most frequent symptoms are dysphagia and epigastric or retrosternal discomfort. We here report a case of esophageal GCT with continued symptoms of retrosternal discomfort, postprandial feeling of fullness, and early satiety despite complete thoracoscopic resection of the tumor.

GBV-C/HGV infection in renal dialysis and transplant patients.

Background: Recently a new human virus (GBV-C/HGV) was identified. With the use of the polymerase chain reaction (PCR) the possibility of a high prevalence of the GBV-C/HGV infection in haemodialysis patients was demonstrated. The aim of the present study was to use a combination of the PCR and a new diagnostic test for antibodies to the viral envelope protein E2 to assess the prevalence of the GBV-C/HGV infection in German patients with renal failure.

Lactic acidosis from thiamine deficiency during parenteral nutrition in a two-year-old boy.

This is a case report of a two-year-old boy who was operated electively for a blind-loop syndrome of the proximal jejunum. Because of the appearance of chylous ascites, parenteral nutrition was carried out postoperatively. The boy developed a severe uncompensated acidosis and paralytic ileus.
