Gonads and genital ducts in a case of male pseudohermaphroditism.

We describe a patient with a 46,XY karyotype, ambiguous external genitalia and partial 17a-hydroxylase deficiency in whom we performed a light microscopic study of the gonads and genital ducts. The right and left testes and epididymides were hypoplastic whereas the right vas deferens was normal, the left one was atretic and a left infundibular remnant was also present, which could be due to a concomitant deficiency in testicular secretions in the early stages of embryonic development or to the possibility of receptor insensitivity for testicular hormones or to a concomitant gonadal dysgenesis.

Intrathecal radioisotopes and phlebography in investigation of ventriculo-atrial shunts in children.

The Authors describe their experience in investigating the functioning and patency of ventriculo-venous shunts in hydrocephalic patients. They examined 41 hydrocephalic children with Pudenz valves, with radioisotope techniques. The radioactive tracers were administered by the lumbar route, by the ventricular route, or directly into the shunt. For lumbar or ventricular administration 131I-HSA, 99mTc-HSA and 169Yb-DPTA were used, whilst 99mTCO4 was the only isotope used for direct introduction into the shunt, effected by piercing the pump of the Pudenz system. The results of these investigations show that introduction of the isotope into the shunt allows obtaining morphological information, depending on the patency of the shunt and on the site of any obstruction. It also provides information about the functioning of the shunt, depending on the presence of hyper- or hypo-shunting. In cases where revision of the distal catheter might be necessary, moreover, phlebographic investigations of the superior vena cava were made. These proved to be particularly useful for indicating the patency of the affluent veins of the heart, thus enabling a precise surgical schedule to be planned prior to operation.

[Ectopic pancreas in Meckel's diverticulitis: a description of a new clinical case].

Ectopic pancreas is a rare congenital abnormality probably due to a derangement of embryologic development of digestive tract. Its frequency is reported in the literature between 0.5-14% predominantly distributed in the stomach, duodenum, jejunum. Such condition is extremely difficult to be diagnosed, in fact most of the case of ectopic pancreas are an accidental finding. We describe a case of ectopic pancreas located in the Meckel's diverticulum, resected at laparotomy performed for colonic disease. Although in retrospective review symptoms from ectopic pancreas are reported in up to 50% of the cases our patient was free of symptoms. In addition the finding of ectopic pancreas in Meckel's diverticulum has been described only seldom in the previous literature. Treatment however should always be resection in order to prevent complications that may occur, although rarely.
