ABSTRACT
A 40-year-old man presented with acute respiratory distress and a productive cough in the past three days with 'currant jelly' sputum. X-ray showed a right upper lobe infiltrate. Culture of sputum showed Klebsiella pneumoniae, consistent with 'Friedländer' pneumonia. The patient was treated with antibiotics but died after a complicated course.

A 39-year-old man was admitted to the ICU after having taken 96 tablets of 500 mg acetylsalicylic acid. Although a high plasma concentration (1040 mg/l) was found, underestimation and misinterpretation of clinical signs and symptoms with decreasing salicylate plasma concentrations led to haemodialysis being postponed. One day after admission the patient suddenly died of cardiovascular collapse due to severe salicylate toxicity. Doctors should be aware that underestimating the severity of salicylate intoxication is a common and dangerous pitfall. Another patient, a 60-year-old woman, was suspected of suffering from toxic alcohol intoxication. She had marked hyperlactaemia (17 mmol/l), which could not be explained from a clinical perspective. However, ethanol was administered intravenously while awaiting the toxic alcohol test results (ethylene glycol: 1300 mg/l). The hyperlactaemia was artificial and caused by an interaction between glycolic acid and lactate on a point-of-care analyser. Doctors should consider artificial hyperlactaemia in patients with ethylene glycol intoxication. The patient recovered.

We retrospectively screened 1836 men who have sex with men (MSM) participating in the Amsterdam Cohort Studies (1984-2003) for hepatitis C virus (HCV) antibodies. HCV incidence was 0.18/100 person-years (PY) in human immunodeficiency virus (HIV)-positive MSM (8/4408 PY [95% confidence interval {CI}, 0.08-0.36]) but was 0/100 PY in MSM without HIV (0/7807 PY [95% CI, 0.00-0.05]). After 2000, HCV incidence among HIV-positive men increased 10-fold to 0.87/100 PY (5/572 PY [95% CI, 0.28-2.03]). Additional hospital cases (n=34) showed that MSM in Amsterdam who acquired HCV infection after 2000 reported high rates of ulcerative sexually transmitted infections (59%) and rough sexual techniques (56%), denied injection drug use, and were infected mainly with the difficult-to-treat HCV genotypes 1 (56%) and 4 (36%). Phylogenetic analysis showed 3 monophyletic clusters of MSM-specific HCV strains. The emergence of an MSM-specific transmission network suggests that HIV-positive MSM with high-risk sexual behaviors are at risk for sexually acquired HCV. Targeted prevention and routine HCV screening among HIV-positive MSM is needed to deter the spread of HCV.
