Review[Radiological diagnosis of adult respiratory distress syndrome (ARDS)].
The bedside chest radiograph represents the imaging modality of choice for diagnosis and monitoring of adult respiratory distress syndrome (ARDS). Imaging findings are strongly influenced by means of mechanical ventilation therapy. ⋯ With CT, the understanding of the underlying pathophysiology and the effects of ventilation therapy (PEEP) could be improved. The role of CT in the clinical routine is still limited due to the high risk to transport patients with ARDS.

Hallucinations are perceptions lacking any extern or physical stimulus. They can affect all senses and may occur in the course of different physical or psychiatric diseases. ⋯ It is important not only to diagnose the basic disorder or illness but also to deal with the patient's anxiety, respect his/her perceptions and to try to establish alternative models of explanation. Apart from therapy of the underlying disorder it is wise to recommend psychotherapy and the attendance of self-help groups.

Angiotensin conversion enzyme inhibitors (ACE-inhibitors) have long been the only possibility to influence the renin angiotensin system (RAS) and its often fatal influences in heart failure. In the last few years specific blockers of the angiotensin 1 receptor (AT I blockers) offered a new possibility for this therapeutic target. ⋯ The first head-to-head studies that compared AT I blockers and ACE-inhibitors and their effect on mortality did not show a reduced mortality in the AT I blocker groups. Based on the available data AT I blockers should be used in heart failure patients who are intolerant of ACE-inhibitors.

Fractures of the distal radius are common counting for 17 percent of all fractures. With conventional radiography they can be classified readily. Magnetic resonance imaging (MRI) is a suitable technique for the detection of occult forms of fractures and of associated soft tissue injuries. ⋯ Indications for arthrography are injuries of the ligaments or of the joint capsule. Fractures and dislocations of the metacarpal, and the phalangeal bones are the most common fractures of the skeletal system. Conventional radiography is the primary imaging technique, followed by sonography and MRI to detect injuries of the ligaments and tendons.
