Review[Sepsis, a complicated syndrome with major medical and social consequences].
Severe sepsis is a life-threatening complication of infection. Due to associated organ-failure treatment in an Intensive Care Unit is usually indicated. Since sepsis is defined by the combination and progression of clinical events, correct definitions are essential to enable good comparison between study results and determination of suitable treatment. ⋯ Direct medical costs of severe sepsis are estimated at [symbol: see text] 19,500 per patient. Costs correlate strongly with the length of stay. Annually Euro dollar 168,6 million is spent on severe sepsis, which represents 0.5% of all health-care costs and 1.7% of the annual hospital budget in the Netherlands.

Case Reports[Life threatening hyperkalemia: the value of the electrocardiogram].
In two men, aged 19 and 64, with chronic renal insufficiency and subacute symptoms of malaise and weakness of the leg muscles, broad QRS complexes were seen in the ECG. The younger patient developed an asystole and resuscitation was unsuccessful. His blood potassium level was found to be 8.3 mmol/l. ⋯ Hyperkalemia is a potentially life-threatening electrolyte disorder that may require immediate treatment. The changes in the ECG, especially widening of the QRS complexes, are the most important clues to the severity of the hyperkalemia. A treatment protocol based on ECG changes may reduce the mortality in these patients.

[Important prognostic significance of a sentinel-node biopsy in patients with malignant melanoma].
To determine the prognostic significance of sentinel-node biopsy in patients with malignant melanoma (unlike the United States, a sentinel-node biopsy is still not routinely performed on melanoma patients in the Netherlands, as the outcomes of prospectively randomised clinical trials are being awaited). ⋯ The patients with a tumour-positive sentinel node had a poorer prognosis with respect to distant metastases than patients with a tumour-negative node. This is the main reason for performing sentinel-node biopsy: to predict the prognosis of the disease. Therefore sentinel-node biopsy should be incorporated into the treatment of patients with malignant melanoma.

Enterococci (Enterococcus faecalis and Enterococcus faecium) are relatively avirulent enteric bacteria that usually only cause infections in immunocompromised patients. Antimicrobial treatment, however, is hampered as enterococci are intrinsically resistant to many antibiotics. For years, vancomycin was considered the last available antibiotic. ⋯ Current advice is to implement the set of infection control measures formulated in 2000, only in those patients colonized by amoxicillin-resistant VRE. The potential dangers of VRE were recently underlined by the proven transmission of the vancomycin-resistance gene from VRE to methicillin-resistant Staphylococcus aureus (MRSA) in two patients in the United States. It is in the interest of the patients that prevalence of VRE and MRSA in Dutch hospitals should be kept as low as possible.

[Recently published European and American guidelines for the diagnosis and treatment of hypertension].
The European Society of Hypertension in conjunction with the European Society of Cardiology has published new guidelines on the management of hypertension. At about the same time, the Joint National Committee in the United States updated the American hypertension guidelines. ⋯ As far as pharmacotherapy is concerned, however, there are major differences between the guidelines. Whereas the European report permits a choice from among several classes of drugs for initial treatment, the American guidelines still consider diuretics to be the first choice.
