Alterations of the nailfold capillary morphology associated with Raynaud phenomenon in patients with systemic lupus erythematosus.

Quantitative analysis of nailfold capillary morphology was performed in age and sex matched groups of 29 patients with systemic lupus erythematosus (SLE) presenting Raynaud phenomenon (RP), 29 RP negative patients with SLE with the same duration of the disease, and 29 healthy controls. Percentages of tortuous, meandering and bushy capillaries were significantly increased in both groups of patients without influence of RP. Capillary density was lower, mean diameters of the capillary loops were higher in patients, especially when RP was present (at the venular branch in microns, mean +/- SD: controls: 15.

[Deliberations and computer computations on the epidemiology of the acquired immunodeficiency syndrome in the Federal Republic of Germany].

A computer simulation of the morbidity and mortality rates of the "Acquired Immunodeficiency Syndrome" in the Federal Republic of Germany was performed. Since sexual intercourse is the main mode of transmission, the population was divided into six groups with different sexual behaviour. In several variations of the program it is demonstrated that during the next 15 years up to 41,000 AIDS patients can be expected.
