Anatomical variations and anomalies of the biliary tract were found more often after expansion of ERCP and MRCP in clinical practice. They have been seen in up to 65% in autopsy and cholangiographic studies. The incidence of congenital anatomical variations of cystic duct was 18 23%. They created a number of difficulties during surgery to the biliary tree, as well as in instrumental extraction ...

Variations in the human karyotype have been found in association with a variety of congenital anomalies and also in the normal population (Miller and Mukherjee, 1962; Court Brown, 1967). Court Brown's population studies (1967) have revealed that between 2 and 3%o of the normal adult population has a karyotype with structural autosomal variations. Occasionally, homologous autosomes reveal differ...

This article is a departure from many prior studies in the literature on Medicare spending in the United States. Previous works have focused on time-invariant or hereditary demographic characteristics and congenital health status. In contrast, this study examined state-level variations in Medicare costs per enrollee with special emphasis on prominent acquired health-related lifestyle attributes...

With the introduction of new surgical procedures an the development of new techniques of cardiac imaging, the normal anatomy, variations and anomalies of coronary arteries have assumed new significance. The coronary arteries may present several variations, in terms of both number and position. The incidence of all coronary anomalies is 0.23% in autopsy series and ranges between 0.3% and 12% in ...
