Congenital neoplasms are very rare in childhood and represent 2.5% of all paediatric tumours; the intrauterine or congenital diagnosis of rhabdomyosarcomas is extremely seldom. The most frequent locations of rhabdomyosarcomas are(More)
Differential diagnosis of the keratocystic odontogenic tumor (KCOT) still represents a challenging problem especially if compared with the dentigerous cyst, which is similar in clinical and radiological course. Histological assessment of this entity may therefore draw crucial attention since various radical procedures are recommended for such lesions in(More)
BACKGROUND An in vitro erythropoiesis assay is a powerful tool for investigating red blood cell (RBC) development and diseases of the erythroid lineage. Most assays, however, failed in either proliferation or terminal differentiation. Here two liquid cultures (LCs) for in vitro generation of RBCs from peripheral blood CD34+ cells were compared.

BACKGROUND Radiation-induced xerostomia still represents a common symptom following radiotherapy of head and neck malignancies, which significantly impairs the patient's quality of life. In this cross-sectional study, human salivary glands were investigated to assess the role of Wnt/β-catenin and TGF-β pathways in the pathogenic process of radiogenic(More)
The ca. 1000 drug-related fatalities that were examined in Hamburg from 1990–1996 by the Institute of Legal Medicine were analysed with respect to consumption of substitute drugs such as methadone. The incidence of methadone-related fatalities has increased in the last two years. The highest incidence was found in 1995 when methadone was detected in the(More)
Objective: In most industrial countries, the numbers of obese pregnant women are rising. Obese women have a high probability for C-Sections and complications due to the surgery. Thus normal birth is especially important for them-an issue that is rarely mentioned in clinical context. Two studies have focused the situation of obese mothers. Materials and(More)
Ein Hyperandrogenismus findet sich bei 5–10% aller Frauen im reproduktionsfähigen Alter. Ergibt die klinische Untersuchung einen Hinweis auf eine sich rasch entwickelnde ausgeprägte Virilisierung, einen neu aufgetretenen Hirsutismus in der Postmenopause oder zeigt sich eine ausgeprägte Hyperandrogenämie, so besteht bis zum Beweis des Gegenteils Verdacht auf(More)
