A Rare Case of Left-Sided Gastroschisis in a Human Museum Specimen.

Gastroschisis is a congenital defect in the anterior abdominal wall resulting in herniation of the abdominal viscera without any fetal membrane covering it. It usually occurs to the right of a normally inserted umbilical cord. The anomaly is associated with intrauterine growth retardation, stillbirth, and preterm delivery. We found a preserved specimen of a 17- to 20-week-old male human fetus presenting with gastroschisis in the Departmental Museum of Anatomy of the Institute of Medical Sciences and SUM Hospital, Bhubaneshwar, a medical college in Eastern India. The fetus showed a hiatus on the left side in the infraumbilical portion of the anterior abdominal wall with evisceration of the liver, spleen, coils of the small intestine, and a segment of the large intestine. The fetus otherwise had no obvious gross abnormality. The case is of particular interest as the incidence of left-sided gastroschisis is very rare.

Accessory mandibular foramina and bifid mandibular canals - an anatomical study

Bifid mandibular canals associated with accessory mandibular foramina are claimed to pose complications in oral surgery and allied procedures resulting in paraesthesia and haemorrhage, due to injury to the divisions of inferior alveolar nerves and vessels passing through them. Sometimes these nerves escape the effect of anaesthetics leading to difficult inferior alveolar nerve block. These variant canals serve as a source of spread of cancer from cortical to cancellous part of the mandible. The current descriptive study included thirty intact, dry, adult human mandibles. They were examined macroscopically to note the presence of accessory mandibular foramina and the accessory mandibular canals arising from them. These aberrant canals were probed and their length was noted. The probed mandibles were X-rayed to observe the course of these canals. The location of the foramina was determined from nearby anatomical landmarks.Six mandibles (20%) showed accessory mandibular foramina. The length of the accessory mandibular canals originating from the accessory mandibular foramina was found to vary from 0.9 cm to 4.5 cm. On X-ray films, the variant canals were noted to proceed towards third molar or towards the angle of mandible. Some of these canals merged with the main mandibular canal. The findings of the study will be helpful in oral surgery, radiology and cancer therapy

Absent portal vein bifurcation: a rare variant and its clinical significance.

Portal vein branching anomaly occurs due to aberration of normal anastomotic patterns and involution of vitelline veins during development of portal vein. Anatomical knowledge of portal vein and its branching pattern is important for hepatobiliary surgeon and gastrointestinal intervention radiologist. We are reporting a case of absence of portal vein bifurcation showing single main intrahepatic portal vein with gradual decreasing caliber distally, in a young female patient on contrast-enhanced computed tomography study of abdomen. Few cases of absence of portal bifurcation have been reported in literature so far.
