Background Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are life-threatening diseases with a high burden of symptoms. Although depression, anxiety, and reduced health related quality of life (HRQOL) have also been reported, a comparative analysis which explores these traits and their underlying factors was lacking. Methods A retrospective analysis of depression, anxiety, and health related QOL was conducted using a Hospital anxiety and depression scale (HADS) as well as the SF-36 HRQOL questionnaire. Results from these tools were compared with haemodynamic and functional parameters in 70 PAH and 23 CTEPH outpatients from a German tertiary care center specializing in pulmonary hypertension. Results Although HRQOL was reduced in both cohorts of patients, individuals diagnosed with CTEPH scored lower in nearly all SF-36 parameters. Significance was noted in both 'mental health' (p = 0.01) and 'mental component summary score' (MCS) (p = 0.02). Depression was also more frequent in patients with CTEPH (56%) than in patients with PAH (30%), (p = 0.03). Overall, depression and anxiety correlated with most SF-36 scales in both PAH and CTEPH. In CTEPH, depression also correlated with the Borg Dyspnea Scale (r = 0.44, p = 0.01). These patients also had significantly lower pCO.sub.2 levels than the PAH cohort reflecting more severe ventilation/perfusion mismatch. All other haemodynamic and functional parameters did not differ across the groups. Conclusion While both cohorts of patients suffer from a reduced HRQOL as well as depression and anxiety, decreases in mental health parameters are more pronounced in the CTEPH cohort. This suggests a strong effort to improve early detection, especially in dyspneic patients with classical risk factors for CTEPH and PAH and argues for mental illness interventions alongside routine clinical care provided to patients diagnosed with PAH or CTEPH., Author(s): Elena Pfeuffer [sup.1] [sup.2] , Holger Krannich [sup.3] , Michael Halank [sup.4] , Heinrike Wilkens [sup.5] , Philipp Kolb [sup.6] , Berthold Jany [sup.1] , Matthias Held [sup.1] Author [...]

In Germany, 10,000 cases of spontaneous pneumothorax are treated inpatient every year. The German Society for Thoracic Surgery, in co-operation with the German Society for Pulmonology, the German Radiological Society, and the German Society of Internal Medicine has developed an S3 guideline on spontaneous pneumothorax and post-interventional pneumothorax moderated by the German Association of Scientific Medical Societies. Method: Based on the source guideline of the British Thoracic Society (2010) for spontaneous pneumothorax, a literature search on spontaneous pneumothorax was carried out from 2008 onwards, for post-interventional pneumothorax from 1960 onwards. Evidence levels according to the Oxford Center for Evidence-Based Medicine (2011) were assigned to the relevant studies found. Recommendations according to grade (A: "we recommend"/"we do not recommend," B: "we suggest"/"we do not suggest") were determined in 3 consensus conferences by the nominal group process. Results: The algorithms for primary and secondary pneumothorax differ in the indication for CT scan as well as in the indication for chest drainage application and video-assisted thoracic surgery. Indication for surgery is recommended individually taking into account the risk of recurrence, life circumstances, patient preferences, and procedure risks. For some forms of secondary pneumothorax, a reserved indication for surgery is recommended. Therapy of post-interventional spontaneous pneumothorax is similar to that of primary spontaneous pneumothorax. Discussion: The recommendations of the S3 Guideline provide assistance in managing spontaneous pneumothorax and post-interventional pneumothorax. Whether this will affect existing deviant diagnostic and therapeutic measures will be demonstrated by future epidemiological studies. [ABSTRACT FROM AUTHOR]

Pulmonary hypertension (PH) is a common consequence of COPD. It has been speculated that patients showing serious PH and vascular remodeling without severe airway obstruction might benefit from vasoactive treatment. There is no approved drug available for COPD-induced PH. Most trials assessing the efficacy of vasoactive drugs in PH have had a follow-up of 12--16 weeks. We report on 4 subjects with COPD and PH. Pulmonary arterial hypertension associated diseases and pulmonary embolism were ruled out. PH persisted despite optimized treatment of underlying COPD and comorbidities, so bosentan was started in all 4 subjects. With bosentan the mean pulmonary artery pressure improved. The average gains in 6-min walk distance at 2--3 months and 8--9 months were 36 m and 145 m, respectively. The maximum gains in 6-min walk distance of the individual subjects were at the 9th, 13th, and 18th month. Oxygenation was stable, and no side effects were observed. We suggest from this experience that in clinical trials of PH in COPD, a follow-up of 16 weeks might cause underestimation of the treatment effects. [ABSTRACT FROM AUTHOR]

The authors discuss a report about the etiology, diagnosis, and treatment of pleural effusion in adults. Topics mentioned include occurrence of benign asbestos pleurisy without further asbestos-related changes, the diagnosis of asbestos-related pleurisy after exclusion of other causes of pleural effusion, and the median latency to onset of pleural effusion after asbestos exposure.

Everyday life is increasingly influenced by digitization. Digitization creates large, often unstructured amounts of data ("big data"), which have been used in consumer industry for years, but yet not widely in medicine. For pulmonology, digitization offers opportunities and risks in different areas like obstructive lung diseases, thoracic oncology, pulmonary rehabilitation, sleep medicine, home mechanical ventilation, and in intensive care medicine. One of the opportunities is that the use of new technologies such as telemedicine and medical apps and the analysis of this new support make it possible to better understand and manage diseases. One of the key advantages is the use of "big data" for displaying dynamic behavior ("trajectories" = movement paths), to better understand disease processes, and to optimize patient management by using analytic techniques such as machine learning. Risks to be considered are data privacy and security as well as the use of artificial intelligence. The vision is to enable precision medicine in pulmonology., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (© Georg Thieme Verlag KG Stuttgart · New York.)

"Choosing Wisely" is an initiative of the German Society of Internal Medicine with the aim to provide recommendations for diagnostic and therapeutic procedures that are of clear medical and scientifically proven benefit, but are rather underused in daily practice. As such, these positive recommendations are indicative of an undersupply. On the other hand, the German Society of Internal Medicine also developed "negative recommendations", pointing out diagnostic and therapeutic procedures that are frequently used but for which there is little or no scientific evidence. They indicate oversupply. So far, the various internal medicine societies have each developed five positive and five negative recommendations, and there are more to come., (Copyright © 2017.

We aimed to characterise the association of pulmonary hypertension due to hypoventilation and exercise capacity, and the haemodynamic and functional changes under noninvasive ventilation. A retrospective analysis was carried out to assess haemodynamics and functional capacity in 18 patients with daytime pulmonary hypertension, due to hypoventilation, at baseline and after 3 months of noninvasive ventilation. Patients presented with a mean±SD pulmonary artery pressure of 49±13 mmHg, preserved cardiac index (3.2±0.66 L·min(-1)·m(-2)), 6-min walking distance of 303±134 m and severely elevated N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. Mean pulmonary artery pressure correlated negatively with maximum work rate (R= -0.72; p=0.03) and 6-min walking distance (R= -0.62; p=0.01). Following noninvasive ventilation we found a significant reduction of mean pulmonary artery pressure (-18 mmHg; p<0.001) and NT-proBNP levels (-2110 pg·mL(-1); p=0.001), and improvement in the 6-min walking distance (+66 m; p=0.008) and maximum work rate (+18 W; p=0.028). Changes in work rate correlated inversely with pulmonary artery pressure (R= -0.75; p=0.031). In this specific cohort with hypoventilation and severe pulmonary hypertension, pulmonary hypertension was associated with reduced exercise capacity. Following noninvasive ventilation, haemodynamics and exercise capacity improved significantly.
