Diagnose und Therapie der Skleritis bei entzündlichen Systemerkrankungen

Aufgrund potenziell visusbedrohender Komplikationen und der Assoziation zu Systemerkrankungen mit einer erhöhten Mortalität sind bei Skleritiden eine gezielte Diagnostik und eine frühzeitige und aggressive entzündungshemmende Systemtherapie notwendig. Neue therapeutische Optionen (wie z. B. Biologica) können in ansonsten therapieresistenten Fällen eine Remission erzielen.

Was durch einen Visusverlust ans Licht kommt

We report a case of a 36-year old patient who suffered from a unilateral painless loss of vision. Ophthalmological examination in the context of a highly reactive syphilis serology revealed an acute syphilitic posterior placoide chorioretinitis (ASPPC). Additional clinical findings were a mucosal lesion on the upper lip, consistent with a plaque opaline and an alopecia specifica as manifestation of secondary syphilis. Treatment consisted in 6x 4 Mio. IE Penicillin G for 14 days and 50 mg Prednison for five days to prevent a Jarisch Herxheimer reaction. The diagnostic measures, therapy and follow up of syphilis, focusing on ocular involvement, are described.

Thoraxschmerzen bei Kindern und Jugendlichen - das Herz?

Chest pain in children and adolescents is a frequent observation, although potentially relevant disease is rather rare and then found in situations with acute presentation. In children with an inflammatory/infectious clinical context the differential diagnosis is oesophagitis, pleuropneumonia or pericarditis. Potentially dangerous complications may be found in youth with predisposing conditions for aortic dissection, pneumothorax or pulmonary embolism, or even in rare instances for an acute coronary complication. In these cases aggressive diagnostic work-up is mandatory. In the frequent elective outpatient evaluation of teenagers with long-lasting episodes of chest pain, relevant underlying cardiovascular disease only rarely can be found as the cause. In the elective outpatient evaluation for chest pain, usually patient history and clinical examination may be enough to track the problem, the main role of the physician is to provide reassurance with minimal but appropriate testing.

The foundations of computer assisted surgery

Using navigation systems in general orthopaedic surgery and, in particular, knee replacement is becoming more and more accepted. This paper describes the basic technological concepts of modern computer assisted surgical systems. It explains the variation in currently available systems and outlines research activities that will potentially influence future products. In general, each navigation system is defined by three components: (1) the therapeutic object is the anatomical structure that is operated on using the navigation system, (2) the virtual object represents an image of the therapeutic object, with radiological images or computer generated models potentially being used, and (3) last but not least, the navigator acquires the spatial position and orientation of instruments and anatomy thus providing the necessary data to replay surgical action in real-time on the navigation system's screen.

Pathophysiology and diagnosis of nephrocalcinosis

Nephrocalcinosis is the result of a myriad of hereditary or acquired diseases in the calcium, phosphate or oxalate metabolism that lead to deposition of calcium containing precipitates within the kidney. Nephrocalcinosis and nephrolithiasis are pathophysiologically tightly related and often co-exist. In the case of recurrent nephrolithiasis, nephrocalcinosis has to be excluded. Stone analysis can yield important clues to the underlying disease process. The best way to diagnose nephrocalcinosis and an accompanying nephrolithiasis is by native computer tomography scans. Untreated, nephrocalcinosis will lead to a progressive decline in renal function and eventually to end stage renal disease. Thus, for each case, the underlying disease process has to be determined and a causative therapy initiated.
