In addition to the well-known clinical early symptoms of hantavirus disease (fever, flank and abdominal pain as well as arthralgia), unusual neurological changes in the context of infection come into focus. The spectrum of neurological symptoms ranges from transient myopia to severe pareses in the context of Guillain-Barré syndrome. In endemic areas, rapid IgM tests for initial assessment are of certain value for differential diagnosis. ⋯ A new systematic review could not confirm a human-to-human transmission previously postulated for South American hantaviruses. While all known human pathogenic hantaviruses are transmitted by rodents, other hantaviruses have been recently detected in shrews, moles, and bats. The clinical significance of these new viruses is quite unclear as yet.

Acute kidney injury contributes significantly to morbidity and mortality in hospitalized patients and is a common complication in the intensive care unit. Identification of patients at risk, elimination of modifiable risk factors and initiation of recommended preventive measures are the main cornerstones to prevent the onset and progression of acute kidney injury. Clinical and biomarker-based risk scores can help assess AKI-risk in specific patient populations. ⋯ Nephrotoxic drugs require a critical risk-benefit assessment and therapeutic drug monitoring when appropriate. Contrast imaging should not be withheld from patients at risk of AKI when indicated but contrast medium should be limited to the smallest possible volume. Finally, recommendations include maintenance of normoglycemia and other measures to optimize organ function in specific patient populations.

[Hyponatraemia in elderly patient - significance, clarification and therapy].
In the general population, the prevalence of mild, usually asymptomatic hyponatremia ranges from 1,7-7,7 %. With increasing age, it rises to 11,6 % in > 75-year-olds. The prevalence is much higher in nursing home residents and hospital patients. ⋯ This is the only way to improve the prognosis and functionality of elderly patients. For SIADH, we have a potent substance available in tolvaptan. In order to be able to recognize the danger of overcorrection in time, the adjustment should take place in the inpatient setting.
