Lyme borreliosis has become the most common vector-borne illness in North Eastern USA and Europe. It is a zoonotic disease, with well-defined symptoms, caused by B. burgdorferi sensu lato, and transmitted by ticks. Lyme borreliosis is endemic in the Netherlands with a yearly incidence of approximately 133 cases/100,000 inhabitants. ⋯ Lyme borreliosis is treated with antibiotics, which are usually highly effective. Recent literature discussing the indications for antibiotic treatment, the dosage, duration and type of antibiotic, as well as indications to withhold antibiotic treatment, are reviewed. This review presents the most recent, and when available Dutch, evidence-based information on the ecology, pathogenesis, clinical presentation, diagnosis, treatment and prevention of Lyme borreliosis, argues against the many misconceptions that surround the disease, and provides a framework for the Dutch physician confronted with a patient with putative Lyme borreliosis.

Case Reports
Tako Tsubo cardiomyopathy, presenting with cardiogenic shock in a 24-year-old patient with anorexia nervosa.
Tako Tsubo cardiomyopathy is a serious condition that is caused by heart failure due to inordinate stress. We here present a case of a young woman with this disorder in association with anorexia nervosa. We postulate a pathophysiological relationship and discuss the management of Tako Tsubo cardiomyopathy.

Community-acquired pneumonia (CAP) is a common and serious disease with significant mortality, morbidity and associated healthcare costs. Severity of pneumonia is related to the extent of the inflammatory response. ⋯ For those two reasons, extended inflammatory response and increasing antibiotic resistance, it is interesting to look at adjunctive non-antibiotic therapeutic strategies aimed at modulation of the inflammatory response or at the micro-organism itself. In this review, we discuss the current knowledge regarding these therapies and their possible role in the future.

A 56-year-old woman developed acute respiratory failure requiring mechanical ventilation due to acute hypokalaemic paralysis. There was no gastrointestinal potassium loss nor was she taking diuretics. ⋯ An acid-load test revealed a renal urine acidification defect, leading to the diagnosis of distal renal tubular acidosis. Normalisation of serum potassium level was established with oral bicarbonate supplementation and temporary potassium supplementation.

Case Reports
Histoplasma capsulatum reactivation with haemophagocytic syndrome in a patient with chronic lymphocytic leukaemia.
We describe a case of haemophagocytic syndrome caused by Histoplasma capsulatum reactivation in a patient with chronic lymphocytic leukaemia treated with fludarabine and alemtuzumab. He presented with fever, pancytopenia, increased serum ferritin, lactate dehydrogenase and soluble interleukin-2 receptor. A bone marrow aspirate showed haemophagocytosis and possibly a yeast infection. ⋯ Haemophagocytic syndrome is a critical condition with high mortality that requires immunosuppressive therapy. The underlying cause should be investigated and treated. In this case a Histoplasma reactivation is described in a severely immunocompromised host years after the patient had left the endemic area.
