[Dilemma situation: Oral anticoagulation in dialysis patients with non-valvular atrial fibrillation].
In patients with intact kidney function and in patients with mild to moderate chronic kidney disease (CKD), strong evidence suggests the use of non-vitamin K dependent oral anticoagulants (NOAC) for preventing ischemic strokes and systemic thromboembolic events in patients with non-valvular atrial fibrillation (nvAF) and elevated thromboembolic risk. In contrast, less evidence is available on the risk-benefit ratio of oral anticoagulation (OAC) in patients with nvAF and severe CKD, particularly in dialysis patients. ⋯ Considering absence of strong evidence, the authors suggest that in dialysis patients with nvAF, in whom the treatment team sees the clear need to prevent thromboembolic events, the use of NOACs or left atrial appendage occlusion should be preferred over treatment with vitamin K antagonists. Any OAC treatment for dialysis patients with nvAF is not in-label in most European countries.

[Transsexualism and transgender medicine - what every internal specialist should know about].
The authors present current findings on transsexualism and its treatment. According to the ICD-10, transsexualism is defined as the "desire to live and be accepted as a member of the opposite sex, usually accompanied by a sense of discomfort with, or inappropriateness of, one's anatomic sex, and a wish to have surgery and hormonal treatment to make one's body as congruent as possible with one's preferred sex." Synonyms of transsexualism are terms such as gender dysphoria reflecting the distress that persons feel due to a mismatch between their gender identity and their sex assigned at birth. ⋯ The diagnosis of transsexualism is made by psychiatrists, but at least five more medical specialties (endocrinologist, surgeon, ear, nose and throat specialist, speech therapist and dermatologist) are involved when treating transsexual persons. Hormonal therapy is a very important element of the treatment process; due to the complexity of transsexualism it should be undertaken by endocrinologists with experience and expertise in this field.

[Unexpected increase in extravascular lung water after acute lung injury].
We report on a 27-year-old female patient presenting with pneumonia and developing acute respiratory distress syndrome. Using transpulmonary thermodilution, an elevated extravascular lung water was detected (17 ml/kg). Patient required lung-protective mechanical ventilation and received antibiotic therapy. Negative fluid balance was targeted. Under this treatment, respiratory function improved, inflammation parameters declined, and extravascular lung water was recurrent (10 ml/kg). Subsequently, extravascular lung water increased to 29 ml/kg. ⋯ As mechanism for this catheter dislocation, we propose a Valsalva maneuver or spontaneous movements of the upper body of the patient. Sudden increase in extravascular lung water may reflect central venous catheter tip dislocation and chest x-ray should be considered to verify catheter tip position.

[Suspected cardiac amyloidosis - diagnostic steps for evaluation].
Cardiac amyloidosis is a rare cause of cardiomyopathy, however, it is part of an underdiagnosed underlying systemic disease. For transthyretin (ATTR) amyloidosis, which is caused by the deposition of incorrectly folded transthyretin, either as the wild-type (wtATTR) or mutated (mATTR) form, novel evidence-based treatment options were recently shown to reduce disease progression as well as hospitalisation rates for heart failure. ⋯ Modern non-invasive imaging (cardio magnetic resonance (CMR) and scintigraphic methods) together with immune fixation with determination of free light chains allow fast and reliable clinical screening for cardiac amyloidosis, whereas endomyocardial biopsy and genetics are used for confirmation of the underlying diagnosis. Interdisciplinary teams including hemato-oncology, neurology, nephrology in addition to cardiology are essential to enable personalized targeted treatment strategies.

24h electrocardiography is an important diagnostic tool in modern cardiology. It has the ability to detect cardiac arrythmias that occur intermittently and therefore can be missed in a standard ECG. However, interpretation of the Holter ECG traces can be difficult and ambiguous. Here, we suggest a step-wise approach to identify all major heart rhythm disorders.
