[Survey of nursing services with regard to mechanical ventilation at home]. / Statuserhebung von Pflegediensten für außerklinische Beatmung.

BACKGROUND: Homecare for mechanically ventilated patients is complex and challenging for homecare institutions. The framework conditions of homecare are regulated by a likewise complex social legislation. The German Respiratory Society (DGP) and the German Interdisciplinary Society for Home Care Ventilation (DIGAB) have published recommendations on the structure of homecare for ventilated patients in their recent guideline and recommended a certification of homecare nursing services. RATIONALE: Prior to a certification process, the homecare task force of the DIGAB conducted a survey in order to compare the current structures with the guideline recommendations. METHODS: Voluntary disclosure of information by means of a written questionnaire consisting of eleven items was requested. RESULTS: 37 homecare institutions with a total of 78 subsidiaries providing service all over Germany returned their questionnaires. While educational standards are mostly in line with the guideline recommendation, it was found that only 43 % of 812 recorded patients followed up with a specialised weaning centre or centre for ventilation. 84 % of these patients were ventilated invasively. In spite of the fact that all homecare institutions took care of invasively ventilated patients, there was a lack of company-owned standards for specific nursing measures. CONCLUSIONS: Homecare for ventilated patients in Germany has reached a decent degree of organisation, while follow-up with specialised centres for ventilation, and with that medical specialist care appears to be underserved. The certification process for homecare institutions should be pursued with emphasis in order to create uniform quality standards. The number of invasively ventilated patients in homecare settings is probably higher than previously estimated and could be the result of a lack of weaning capacity.

Elevated B-cell activating factor BAFF, but not APRIL, correlates with CSF cerebellar autoantibodies in pediatric opsoclonus-myoclonus syndrome.

Childhood opsoclonus-myoclonus syndrome (OMS) occurs idiopathic or, in association with a neuroblastoma, as a paraneoplastic syndrome. Since autoantibodies were identified in some patients, an autoimmune pathogenesis has been suspected. While the newly discovered B-cell activating factors BAFF and APRIL are involved in systemic autoimmune diseases, their association with neuroimmunological diseases is hardly understood. We here investigated the BAFF and APRIL levels in serum and cerebrospinal fluid (CSF) of OMS patients and their correlation with surface-binding autoantibodies. BAFF and APRIL were both determined by ELISA, and autoantibodies to cerebellar granular neurons (CGN) have been investigated by flow cytometry in 17 OMS patients, 16 neuroblastoma (NB) patients, 13 controls and 11 children with inflammatory neurological diseases (IND). BAFF, but no APRIL, was elevated in the CSF of OMS children and IND children. However, in contrast to IND patients, OMS patients did not have a blood-brain-barrier disturbance, indicating that BAFF was produced intrathecally in OMS patients, but not in IND patients. CSF BAFF levels showed a correlation with CSF CGN autoantibodies (r(2)=0.58, p<0.05). These data indicate that an activated B-cell system in the cerebrospinal fluid is involved in the pathogenesis of OMS, and BAFF may be a candidate parameter for the activation of B-cell immune system.

Differential intraocular pressure as an indirect measure of generated muscle force.

Differential intraocular pressure offers a painless, non-invasive, reliable test for evaluating incomitant strabismus. These data can be used in selecting a recess-resect vs. a muscle transfer procedure and, combined with findings of the traction test, can direct the surgeon in doing a full tendon transfer or a rectus muscle union with recession of the antagonist.
