Abstract
Sleep disordered breathing with predominant obstructive or central apnea is an under-recognized but highly prevalent comorbidity in patients with chronic heart failure. As the severity of heart failure increases the prevalence of central sleep apnea (CSA) and Cheyne-Stokes respiration (CSR) is also much more frequent. Cheyne-Stokes respiration is characterized by alternating periods of crescendo and decrescendo respiration followed by central apnea. Present data indicate that CSA-CSR is not only a compensatory response to severe heart failure but also a predictor of worse prognosis. However the results on long-term mortality are not consistent. The prognostic importance of night- and daytime CSR has to be further elucidated. Increased sympathetic nervous activity has been proposed to play a mayor role concerning progression and outcome of chronic heart failure by CSA-CSR.

Abstract
Particularly in young children the diagnosis of asthma is difficult and mostly based on clinical symptoms like wheezing, cough and dyspnea. Children with nocturnal wheezing often suffer from a low quality of sleep and impaired sense of well-being during the day. Physicians recommend that parents record the frequency of asthma attacks or symptoms to help manage their children's disease. The lack of an appropriate method for standardized and objective monitoring makes asthma management difficult. The aim of this paper is to present a new method for automated wheeze and cough detection and analysis. The mobile LEOSound recording and analysing system described here should help improve diagnosis and monitoring of asthma symptoms in children.

Abstract
Long-term oxygen treatment (LTOT) has been demonstrated to improve prognosis in patients with chronic respiratory insufficiency. In terms of pathogenesis, improved oxygenation, reduction of pulmonary artery pressure as well as reduction of respiratory work are important. Since there are considerable differences between the LTOT systems, individually tailored therapy is needed. In particular, the mobility aspects of the patients must be taken into consideration. It is important to distinguish between stationary/mobile devices with a liquid oxygen system and stationary/mobile devices with oxygen concentrator. Oxygen titration should be performed in relation to rest and activity phases (e. g. 6 minute walk test) as well as in relation to the sleep phase. Employing devices with demand-controlled valves should be critically examined. This can be undertaken only under physician orders and requires continuous monitoring.

Abstract
Objective: To demonstrate that a PGD program can be successfully established after the 2011 verdict of the German Bundestag concerning PGD. Material and Method: Eight years previously, the couple had had a daughter who suffered from clinically manifest hemophilia A due to an unbalanced X-inactivation, as well as microdeletion syndrome resulting in severe physical and mental disability. The couple wished to have a second child but refused the idea of a "trial" pregnancy. Given the indications for both, it was necessary to carry out polar body diagnosis (PBD) to rule out hemophilia A and, during the same cycle, a subsequent PGD on the blastocysts to rule out genetic aberrations. The PBD and PGD (trophectoderm biopsy, TEB) were performed after high-dosage ovarian stimulation and ICSI fertilization of the oocytes. A blastocyst was successfully transferred on day 6. Results: The patient conceived immediately. The pregnancy developed normally and the patient gave birth to a girl in the 40th week of pregnancy. Post-natal examinations showed that the baby is free from hemophilia A and is developing normally both physically and mentally. Conclusion: Establishment of a PGD program is now possible after legalization of PGD in Germany. It is possible to apply two investigative techniques in a single treatment cycle if multifactorial diagnosis is required.

Abstract
Obstructive sleep apnea and central sleep apnea with Cheyne-Stokes respiration are associated with an increased risk of cardiac arrhythmia. Apnea- associated arrhythmia may contribute to sudden cardiac death and premature mortality in those patients. Both forms of sleep apnea excert strong modulatory effects on the autonomic system with a special autonomic profile. Profound vagal activity is leading to bradyarrhythmias, and sypathico-excitation to tachyarrhythmias. Atrial fibrillation and ventricular arrhythmias in obstructive and central sleep apnea patients are mainly found in combination with cardiovascular comorbidity (coronary heart disease, hypertensive heart disease, chronic heart failure). Bradyarrhythmias in OSA are induced by a cardioinhibitory vagal reflex due to obstructed airway. CPAP-therapy has been demonstrated to reduce arrhythmias.
