Review[Sudden cardiac death in familial hypertrophic cardiomyopathy. Identification of high-risk patients].
Hypertrophic cardiomyopathy (HCM) is a relatively frequent, genetically determined primary cardiomyopathy, characterized by most often asymmetric hypertrophy of the ventricular septum with or without systolic obstruction of the left ventricular outflow tract. HCM is a genetically heterogeneous disease, with 12 different disease-causing genes beeing indentified to date. Histologically the disease is characterized by hypertophy and disarray of myofibrils as well as by an increase in myocardial fibrosis. ⋯ The implantation of a cardioverter/defibrillator is first-line therapy in patients with documented ventricular tachycardia/fibrillation or patients who have survived sudden cardiac death. These devices also play an important role in the primary prevention of sudden cardiac death in HCM. Algorithms and scores are available to estimate the risk of sudden death, however, the decision to implant a cardioverter/defibrillator remains an individual decision in every single patient.

Case Reports[Recurrent strongyloidiasis as an indicator of HTLV-1 infection].
A 53-year-old West African man presented two years after a travel to Guinea because of severe headache, neck stiffnes, fever and pruritus. The patient had been in orthopedical treatment for the last five months. ⋯ Although both strongyloidiasis and HTLV-1 infections occur most frequently in tropical areas, these may also be observed in temperate regions. Suppression of the immune system by HTLV-1 differs from that by HIV. CD4+-lymphocytes were rarely decreased. Prolonged treatment with ivermectin in a dosage exceeding the current recommendations may be required in HTLV-1 infected patients and was well tolerated. The unusual presentation of the infection with muscular symptoms contributed to the delay of the diagnosis. HTLV-1 positive patients must be monitored for years. They and their partners must be instructed how to prevent transmission of the virus.
