Leishmaniasis is a rare, non-notifiable disease in Germany. Epidemiological and clinical data, therefore, are scarce. Most infections seen in Germany are contracted outside the country. The German surveillance network for imported infectious diseases (Surveillance Importierter Infektionen in Deutschland, or SIPMID) recorded 42 cases of imported(More)
Hirschsprung disease (HD) is the most prevalent congenital gastrointestinal motility disorder. The pathogenesis of HD is defined as a functional intestinal obstruction resulting from a defect in the intrinsic innervation of the distal bowel. In addition to the enteric nervous system, the interstitial cells of Cajal (ICC) play an important role in the(More)
BACKGROUND Malignant ectomesenchymoma (MEM) is a soft tissue tumor with heterologous rhabdomyoblastic components believed to arise from pluripotent migratory neural crest cells. To date merely 50 cases have been published and the knowledge about the course of disease and optimal treatment is limited. METHODS Six patients with MEM were registered(More)
OBJECTIVE To assess the suitability of a laparoscopic Tenckhoff catheter implantation (TCI) technique in children. DESIGN Prospective nonrandomized controlled study. SETTING Laparoscopic and conventional TCIs in children were performed in a tertiary-care hospital. PATIENTS Between 1998 and 2001, 25 laparoscopic and 23 conventional TCIs were performed(More)
Ultrasound has developed as the method of choice for diagnosing intussusception. Ultrasound-guided enema reduction is the standard method for treating intussusception. This retrospective study evaluates the efficacy and safety of ultrasound in diagnosis and treatment of intussusception performed solely by pediatric surgeons. Charts were studied of all(More)
Intraoperative radiotherapy (IORT) permits the application of a single large radiation dose to a malignant mass at the time of surgery sparing adjacent normal tissue from irradiation. Since 1996 we have used IORT to treat 13 children with neuroblastoma, stage 3 - 4. In all cases the tumour was not radically resectable at the first operation. Ultrasound, CT(More)
Numerous researchers studied the morphology of the testicular descent, including the possible function of the gubernaculum. However, a clear illustration of this process is still missing. The aim of this paper was to illustrate the embryology of the testicular descent in the rat by scanning electron microscopy. In a first phase of the intra-abdominal(More)
Pediatric intestinal motility disorders affect many children and thus not only impose a significant impact on pediatric health care in general but also on the quality of life of the affected patient. Furthermore, some of these conditions might also have implications for adulthood. Pediatric intestinal motility disorders frequently present as chronic(More)
According to recent studies, the percentage of neonates suffering a combination of very low birth weight (VLBW) and intestinal malformation or diseases that require surgery has increased. As opposed to mature newborn, split stoma is the therapy of choice in VLBW infants. These neonates and patients with other causes for a congenital or acquired short-bowel(More)
There is ongoing controversy regarding the surgical treatment of necrotizing enterocolitis (NEC) in infants with extremely low birth weight (ELBW). We hypothesize that primary laparotomy is a safe and effective treatment for all infants with surgical NEC. We retrospectively compared a group of ELBW infants (<1,000 g, group A, n = 39) with preterm infants(More)
