Chronic thromboembolic pulmonary hypertension (CTEPH) results from inadequate recanalization of the pulmonary circulation after pulmonary thromboembolism. Its 2-year prevalence is 1-4% . If untreated, patients with CTEPH have a mean life expectancy of less than three years. Fortunately, a number of effective treatments are now available. ⋯ The timely diagnosis of CTEPH, followed by referral to a specialized center, is now more important than ever, because treatment options are now available for nearly all of the forms in which this disease can manifest itself.

Chronic obstructive pulmonary disease (COPD) is common in Germany, with a prevalence of 13.2%. The available treatments are exclusively symptomatic, except for lung transplantation, from which no more than a few patients can benefit. Over the past decade, endoscopic lung volume reduction (ELVR) has broadened the therapeutic spectrum for patients with advanced pulmonary emphysema. ⋯ Endoscopic lung volume reduction has broadened the therapeutic spectrum for selected patients with advanced pulmonary emphysema. Further prospective trials are needed to evaluate the benefits, risks, and long-term effects of the available techniques for ELVR.

Estimates of the prevalence of chronic obstructive pulmonary disease (COPD) in Germany range from 1.9% to 13.2%, depending on the population studied and the investigative methods used. About 30% of all patients already have severe airway obstruction by the time the condition is diagnosed. ⋯ COPD may begin with symptoms that are only mild at first even in a longstanding smoker. The available diagnostic techniques need better prospective validation with respect to relevant endpoints, including mortality, symptom progression, quality of life, and frequency of exacerbations.

The standard recommendation to date has been that acute hypoproliferative thrombocytopenia should be treated with a prophylactic platelet transfusion if the morning platelet count is less than 10 000/μL, or less than 20 000/μL if there are additional risk factors. For chronic thrombocytopenia, transfusion has been recommended if the platelet count is less than 5000/μL. In Germany, half a million platelet transfusions are now being given every year, and the number is rising. New studies indicate, however, that a more restrictive transfusion strategy is justified. ⋯ The number of platelet transfusions could be safely lowered by a more restrictive transfusion strategy that takes account of the risk of bleeding, as recommended in the hemotherapy guidelines.

15% of children and adolescents in Germany are overweight, including 6.3% who are affected by obesity. The efficacy of conservative weight-loss treatments has been demonstrated, but there has not yet been a detailed analysis of their efficacy in terms of the amount of weight loss that can be expected. We re-evaluated the available evidence on this question, with particular attention to the methodological quality of clinical trials, in order to derive information that might be a useful guide for treatment. ⋯ The available evidence consistently shows that only a modest degree of weight loss can be expected from conservative treatment. Families seeking treatment should be informed of this fact. Future research should focus on determining predictive factors for therapeutic benefit, and on the evaluation of additional types of psychological intervention to promote coping with obesity.
