We describe slipped capital femoral epiphysis in 4 members of a black, obese family, who were all first-degree relatives. The aetiology of slipped capital femoral epiphysis is unknown, although it is thought to be multifactorial. Genetic predisposition and environmental factors have been associated with the condition. A familial incidence with at least two cases in the same family has been reported. In epidemiological studies, this incidence ranges from 3% to 35%. Our cases were investigated in an attempt to find a possible aetiological genetic factor. A genetic predisposition with an autosomal dominant pattern of transmission is suggested, although environmental variables must be considered as provocative factors.

Thrombophilias, whether inherited or acquired, are a topic of increased interest in women’s health. Factors that enhance thrombus formation in the presence of thrombophilia include oral contraception, hormone replacement therapy, pregnancy and the puerperium. The risk of venous thomboembolism with hormonal contraceptive use is greater in women with underlying thrombophilias, and thrombosis usually occurs earlier than in women without defined thrombophilias. The degree of increased risk varies according to the underlying thrombophilic defect, the largest bulk of evidence referring to women with Factor V Leiden or prothrombin gene mutation. However, most instances of thrombosis occur due to a combination of inherited, acquired and environmental factors. Before starting oral contraception it is important to screen patients to identify those at increased risk of thrombosis.
