Prevalence of HLA-B27 among donors and recipients for renal and bone marrow transplantation in Mauritius.

In this study, the frequency of the tissue antigen HLA-B27 is studied in 494 donors and recipients for renal and bone marrow transplantation on the multi-ethnic island of Mauritius, the majority of the population of which is of Indian descent. Although results showed a prevalence rate of 4.3%, inter-racial variation was not observed between the major ethnic groups (P>0.05). These findings are comparable with the results of studies on HLA-B27 prevalence rate in India, and lend support to the argument that the HLA-B27 test should not be used on a routine basis to diagnose HLA-B27-related rheumatic disorders in Mauritius.

Anatomical basis for the clinical application of the arterial supply of musculus pectoralis major.

The pattern of arterial supply to the various parts (clavicular, sternocostal and aponeurotic) of the pectoralis major muscle was studied in 7 cadaver dissections and 10 angiograms by injecting a radio-opaque substance. Three main arteries supplied the muscle, i.e. the pectoral branch of the thoracoacromial trunk (TAT-PB), the lateral thoracic artery and the perorating branch of the internal thoracic artery, supported by other branches of the TAT and the superior thoracic artery. It is observed that the TAT-PB, a chief vascular pedicle, anastomoses freely with other arteries and supplies most parts of the muscle. The present study is mainly focussed on the exclusion of the chief vascular pedicle of muscle to eliminate the confusion of previous studies and prevent the unnecessary hindrance and complications of the muscle flap.
