Chronic lymphocytic leukemia (CLL) mainly affects older persons and is the commonest form of leukemia, with an incidence of 6 cases per 100 000 per- sons per year. In Germany, approximately 1000 men and 850 women die of CLL each year. ⋯ Recent progress in the development of novel treatment options gives hope that CLL may soon be a controllable disease. Even at present, chemoimmuno- therapy can achieve a progression-free survival of more than eight years in certain genetically defined subgroups of CLL patients.

Hypertrophic cardiomyopathy (HCM) is caused by mutations in a number of genes. Its prevalence is 0.2% to 0.6%. ⋯ In the absence of evidence from randomized comparison trials, a suitable method of reducing the gradient should be determined by an HCM team in conjunction with each individual patient. Important criteria for decision-making include the anatomical findings and any accompanying illnesses.

Pilonidal disease is an acute or chronic infection in the subcutaneous fatty tissue, mainly in the natal cleft. Its incidence in Germany in 2012 was 48 cases per 100 000 persons per year. ⋯ Further randomized trials are needed to clarify the role of newer techniques in the treatment of pilonidal disease.
