Impact of vital status investigation procedures on estimates of survival in cohorts of HIV-infected patients from Sub-Saharan Africa.

In HIV cohorts in sub-Saharan Africa, documenting vital status of patients lost to follow-up is a major challenge. The effect of specific vital status investigation procedures (VSIPs) on the number of known deaths has never been shown.

A five year retrospective study on pemphigus and pemphigoid.

In a five year period 73 cases of pemphigus vulgaris (PV) and 94 of bullous pemphigoid (BP) were studied to investigate important parameters for these diseases. From the results it was found that the incidence of PV was higher in women whereas that of BP was almost equal in both sexes. The incidence of PV was highest in the sixth decade but was highest in the eighth decade for BP.
