Zusammenfassung Die Anzahl tracheotomierter dysphagischer PatientInnen im klinischen und außerklinisch-ambulanten Setting der damit einhergehende Behandlungsbedarf steigen kontinuierlich. Neufassung Richtlinie des Gemeinsamen Bundesausschusses über die Verordnung außerklinischer Intensivpflege (AKI) sieht zudem vor, dass in AKI regelmäßig evaluiert werden, um Therapiepotenzial nach stationärer Entlassung zu erkennen fördern. Eine besondere Rolle nimmt dabei Dysphagietherapie ein, da ohne...

SUMMARY Plasma ACTH levels in response to metyrapone and insulin hypoglycaemia were compared subjects with normal pituitary‐adrenal function. After a single dose of 2 g given snack at midnight, the level was 468 ng/l ± 66 (SEM) 07.30 h next morning (mean increment approximately nine fold over values). insulin‐hypoglycaemia peak 369 31 (SEM). Peak greater than 200 achieved twenty twenty‐one (95%) after twenty‐four (83%) insulin. No major side effects noted metyrapone. It is concluded that...

In Germany, about 5 million people of all ages suffer from dysphagia. Due to demographic change and improved medical care, the incidence swallowing disorders is expected increase. Dysphagia associated with an increased morbidity mortality leads a considerable financial burden on health systems. The two most common causes dysphagia are neurological head neck cancer. Diagnostics therapy have developed continuously over past decades. particular, flexible endoscopic evaluation (FEES) has become...

The authors studied the contribution of seven clusters Lazarillo-expressing cells to primary axon scaffold brain in grasshopper Schistocerca gregaria from 26% 43% embryogenesis. Each cluster, which was numbered according when Lazarillo expression first appeared, uniquely identifiable on basis its stereotypic position and number it contained. At no time during embryogenesis found neuroblasts: It only progeny. For ease analysis, axogenesis followed a cell cluster that contained single (the...
