Iron and zinc deficiency is associated with memory deficits in children. There is a marked improvement in memory after supplementation. Post supplementation IQ scores do not show significant improvement in deficient groups in 6-8 year olds.

Pulsations of the dorsalis pedis artery are commonly used to evaluate the peripheral arterial diseases like thromboangiitis obliterans (TAO) or Buerger’s disease, in lower limbs. Dorsalis pedis artery is a direct extension from the anterior tibial artery and major vascular supply for the dorsum of the foot. But arterial variations in lower limbs are common due to rich distal anastomoses around the ankle joint. Absence of dorsalis pedis arterial pulse does not indicate peripheral arterial disease always as it is sometimes replaced by the enlarged perforating branch of peroneal artery, it may be absent or very thin, deviate laterally on the dorsum of foot. Aim of the present study is to observe the variations in origin, course and branching pattern of dorsalis pedis artery because of its clinical significance. During routine dissection of lower limbs for undergraduates we came across rare variations in the dorsalis pedis artery in its origin, course and branching pattern. Normal anatomic description was found in 27 limbs. In 13 specimens we noted variations, includes bilateral anomalous origin of dorsalis pedis artery, bilateral lateral deviation of dorsalis pedis artery, double dorsalis pedis artery, trifurcation of dorsalis pedis artery and absence of arcuate artery. Knowledge about the arterial variations around the ankle is important to orthopaedic, vascular surgeons and radiologists to prevent complications during surgical interventions.

Celiac trunk is the artery of foregut, arising from the abdominal aorta at the level of T12/L1 vertebral body. It extends approximately 1.5 to 2 cm horizontally forwards before dividing into three branches: left gastric, common hepatic, and splenic arteries. Out of the three ventral branches of abdominal aorta, celiac trunk is more prone to have variations. During routine dissection of abdomen for undergraduate students we found some rare variations in the branching pattern of the celiac trunk. Absence of celiac trunk with hepatomesenteric trunk, quadrifurcation with dorsal pancreatic artery arising from it, quadrifurcation with middle colic artery arising from it, left inferior phrenic artery arising from celiac trunk, highly tortuous splenic artery supplying distal 1/3rd of transverse colon and hepatosplenic trunk. Knowledge of such variations is essential for liver and pancreas transplantations, pancreaticoduodenectomy, radiological abdominal interventions, laproscopic surgeries, and in trauma of the abdomen.
