Basilar artery thrombosis during sexual intercourse.

An ischemic stroke during sexual intercourse is very rare. A basilar artery thrombosis during sexual intercourse has not been described previously. We report a young woman with a life-threatening basilar artery thrombosis during sexual intercourse, with a resulting locked-in syndrome.

Rituximab-Containing Treatment Regimens May Imply a Long-Term Risk for Difficult-To-Treat Chronic Hepatitis E.

Hepatitis E virus (HEV) infection is an emerging disease in industrialized countries which is usually characterized by a self-limited course. However, there is an increased risk of HEV persistence in immunocompromised risk populations, comprising patients following solid organ transplantation or hematological malignancies. Recently, chronic HEV infection following rituximab-containing treatment regimens has been described.

Teaching medicine with the help of "Dr. House".

TV series such as "House MD", "Grey´s Anatomy" or "Emergency Room" are well perceived by medical students. Seminars featuring medical TV series such as "House MD" might serve as door-opener to attract medical students to learn more about rare diseases. The TV series "House MD" is troublesome for the main character Dr.

Foodborne botulism due to ingestion of home-canned green beans: two case reports.

Background: Foodborne botulism is a life-threatening, rapidly progressive disease. It has an incidence of less than 10 cases per year in Germany and mostly affects several previously healthy people at the same time. The only specific treatment is the administration of botulism antitoxin.

Neisseria meningitidis causes cell cycle arrest of human brain microvascular endothelial cells at S phase via p21 and cyclin G2.

Microbial pathogens have developed several mechanisms to modulate and interfere with host cell cycle progression. In this study, we analysed the effect of the human pathogen Neisseria meningitidis on cell cycle in a brain endothelial cell line as well as in primary brain endothelial cells. We found that N.

Gene expression profiles of human dendritic cells interacting with Aspergillus fumigatus in a bilayer model of the alveolar epithelium/endothelium interface.

The initial stages of the interaction between the host and Aspergillus fumigatus at the alveolar surface of the human lung are critical in the establishment of aspergillosis. Using an in vitro bilayer model of the alveolus, including both the epithelium (human lung adenocarcinoma epithelial cell line, A549) and endothelium (human pulmonary artery epithelial cells, HPAEC) on transwell membranes, it was possible to closely replicate the in vivo conditions. Two distinct sub-groups of dendritic cells (DC), monocyte-derived DC (moDC) and myeloid DC (mDC), were included in the model to examine immune responses to fungal infection at the alveolar surface.

CCAAT/enhancer-binding protein homologous (CHOP) protein promotes carcinogenesis in the DEN-induced hepatocellular carcinoma model.

Background And Aims: C/EBP homologous protein (CHOP) plays pro-apoptotic roles in the integrated stress response. Recently, a tumor suppressive role for CHOP was demonstrated in lung cancer via regulation of tumor metabolism. To explore the role of CHOP in hepatocarcinogenesis, we induced hepatocellular carcinoma (HCC) in wild type (wt) and CHOP knockout (KO) mice using the carcinogen N-diethylnitrosamine (DEN).

HCV causes chronic endoplasmic reticulum stress leading to adaptation and interference with the unfolded protein response.

Background: The endoplasmic reticulum (ER) is the cellular site for protein folding. ER stress occurs when protein folding capacity is exceeded. This stress induces a cyto-protective signaling cascades termed the unfolded protein response (UPR) aimed at restoring homeostasis.

Genetic variation in IL28B is associated with chronic hepatitis C and treatment failure: a genome-wide association study.

Background & Aims: Hepatitis C virus (HCV) induces chronic infection in 50% to 80% of infected persons; approximately 50% of these do not respond to therapy. We performed a genome-wide association study to screen for host genetic determinants of HCV persistence and response to therapy.

Methods: The analysis included 1362 individuals: 1015 with chronic hepatitis C and 347 who spontaneously cleared the virus (448 were coinfected with human immunodeficiency virus [HIV]).

CC chemokine receptor 5 delta32 polymorphism in two independent cohorts of hepatitis C virus infected patients without hemophilia.

Recently CC chemokine receptor 5 (CCR5) related immune mechanisms and a functional mutation of the CCR5 gene have been implicated in hepatitis C virus (HCV) infection in a cohort of predominantly hemophiliac patients. The present study investigated the frequency and clinical consequences of the CCR5 Delta32 mutation in two genetically homogeneous populations of HCV infected patients with a different risk profile for infection. Genomic DNA samples from 333 German patients with chronic HCV infection were screened by PCR for the presence of the CCR5 Delta32 polymorphism.
