[Interdisciplinary, collaborative D-A-CH (Germany, Austria and Switzerland) consensus statement concerning the diagnostic and treatment of myalgic encephalomyelitis/chronic fatigue syndrome].

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a severe, chronic multisystemic disease which, depending on its severity, can lead to considerable physical and cognitive impairment, loss of ability to work and the need for nursing care including artificial nutrition and, in very severe cases, even death.The aim of this D-A-CH (Germany, Austria, Switzerland) consensus statement is 1) to summarize the current state of knowledge on ME/CFS, 2) to highlight the Canadian Consensus Criteria (CCC) as clinical criteria for diagnostics with a focus on the leading symptom post-exertional malaise (PEM) and 3) to provide an overview of current options and possible future developments, particularly with regard to diagnostics and therapy. The D-A-CH consensus statement is intended to support physicians, therapists and valuer in diagnosing patients with suspected ME/CFS by means of adequate anamnesis and clinical-physical examinations as well as the recommended clinical CCC, using the questionnaires and other examination methods presented.

Intra-operative extracorporeal membrane oxygenation use in pediatric lung transplantation--the Zurich experience.

There is a lack of data regarding use of ECMO in children undergoing lung transplantation. We evaluated our experience of ECMO in pediatric lung transplant recipients. All patients (<18 yr) who underwent lung transplants between 1997 and 2011 were included (17 children; nine males; median age 16 yr), and the use of intra-operative ECMO evaluated.

Pandemic 2009 H1N1 influenza virus vaccination in lung transplant recipients: coverage, safety and clinical effectiveness in the Zurich cohort.

Background: Pandemic 2009 H1N1 influenza virus (H1N1) infection is considered harmful to lung transplant recipients (LTRs). Vaccination against this virus is recommended for LTRs, but little is known about associated benefits and risks. Our aim in this study is to document the safety and clinical effectiveness of the H1N1 vaccine in LTRs.

Chronic lymphocytic leukaemia, dyspnoea and "tree-in-bud" sign on chest CT scan.

Chronic lymphocytic leukaemia (CLL) is a common disorder. Patients typically present with lymphadenopathy, splenomegaly and marked lymphocytosis (often >100 000/μl). Although pulmonary involvement from CLL can be found in more than one third of patients on autopsy, respiratory symptoms caused by the disease itself are not often reported.

Influence of altitude exposure on coronary flow reserve.

Background: Although no data exist on the effect of altitude exposure on coronary flow reserve (CFR), patients with coronary artery disease (CAD) are advised not to exceed moderate altitudes of approximately 2500 m above sea level. We studied the influence of altitude on myocardial blood flow (MBF) in controls and CAD patients.

Methods And Results: In 10 healthy controls and 8 patients with CAD, MBF was measured by positron emission tomography and 15O-labeled water at rest, during adenosine stress, and after supine bicycle exercise.
