[Acute renal failure and rare severe complication of systemic steroid treatment in a 73-year-old woman]. / Akutes Nierenversagen und seltene schwere Komplikation einer systemischen Steroidtherapie bei einer 73­Jährigen.

This article reports about a 73-year-old woman of Bosnian descent who presented with acute renal failure. A renal biopsy was diagnostic for a postinfect necrotizing and extracapillary proliferative glomerulonephritis. The patient reported a febrile infection fever 2 weeks previously. The diagnostics did not reveal any indications of an ongoing infection. The glomerulonephritis responded to treatment with systemic steroids. The patient was readmitted to hospital 6 weeeks later in a severely ill condition. A gastric biopsy revealed a Strongyloides stercoralis infestation. Due to the systemic steroid therapy the patient had developed a so-called hyperinfection syndrome and died despite treatment on the intensive care unit. This case illustrates the need for awareness of this rare parasitosis, particularly in patients from endemic areas. A likely causal relationship with the glomerulonephritis is discussed and an overview of the diagnostics, course of the disease and treatment of this parasitosis is given.

[Cannabinoid hyperemesis syndrome inducing acute prerenal failure and electrolyte disturbance]. / Akutes prärenales Nierenversagen und Elektrolytentgleisung durch das Cannabis-induzierte Hyperemesis-Syndrom.

HISTORY AND CLINICAL FINDINGS: A 36-year-old patient presented to the psychiatric clinic with presumed worsening of a chronic psychosis. INVESTIGATIONS: Laboratory values revealed acute renal failure and electrolyte imbalance. A further diagnostic work-up including urine analysis as well as abdominal und retroperitoneal sonography was normal. DIAGNOSIS, THERAPY AND CLINICAL COURSE: By exact history taking the clinical diagnosis of a cannabinoid hyperemesis syndrome (CHS) was established. Symptomatic treatment with intravenous fluids and electrolytes together with strict cannabis abstinence completely resolved all symptoms and normalized all pathologic values. CONCLUSION: Recreational use of cannabis is widespread. It may induce a widely unknown syndrome characterized by nausea, vomiting and crampy abdominal pain accompanied by frequent hot showers or bathing. This syndrome should be recognized as a potential cause of acute prerenal failure.

[41-year-old female patient with ST-elevation myocardial infarction and multiple arterial emboli]. / 41-jährige Patientin mit ST-Hebungsinfarkt und multiplen arteriellen Embolien.

A 41-year-old woman presented with acute angina in the emergency unit. Additionally, she reported pain in both legs and a weight loss of 5 kilograms within the last 10 days. ECG revealed an acute anterior myocardial infarction. However, immediate coronary angiography showed open arteries with minimal arteriosclerosis. A characteristic rise of cardiac enzymes together with an akinesis of the anterior wall and an adjacent mural thrombus was highly suggestive of a transient coronary thrombosis. Further investigations showed occlusion of multiple arteries in both legs and a splenic infarct. Although there was a typical risk profile including smoking, hyperlipidemia and regular estrogen medication, a further work-up was started. Urin analysis was decisive for the presence of proteinuria and a severe nephrotic syndrome. The definite diagnosis was made by direct biopsy of the kidney that revealed the characteristic findings of a minimal change glomerulopathy. Rapid remission could be induced by high-dose oral steroids. During routine work-up of coronary syndromes, especially in those with normal coronaries, rare but treatable causes of myocardial infarction and coagulopathy have to be thought of and should carefully be excluded.
