[Cervical neuroblastoma in a newborn infant].

A case of cervical neuroblastoma is presented. It was treated by surgical resection followed by homolateral node dissection. No chemotherapy or radiotherapy was done, and patient is free of disease at the present time.

Intraspinal migration of a rectal foreign body.

This is a description of a rare case of intraspinal foreign body, a clinical thermometer bulb, which after perforating the rectum migrated through the second left sacral foramina and sacral canal up to the epidural space at S1-L5 level. A first attempt to remove it by laparotomy while it was still in the retrorectal space proved unsuccessful. Retrieval was finally achieved by laminectomy.

[Study of biliary tract atresia with HIDA Tc 99].

This report has been motivated to assess the permeability of portoenterostomy with isotopic methods (HIDA Tc 99) in two cases of biliary tract atresia. Both cases have followed a good evolution during 1 1/2 and 8 years respectively, with vanishing of the icterus and achieving an acceptable biliary flow. We used the hepatic gammagraphy with HIDA Tc 99 to evaluate biliary drainage and functional status of biliary tract.

[Results and complications of CSF shunting in hydrocephalus].

Fifty four patients with hydrocephalus treated with surgical derivations were evaluated in retrospect. The total number of derivations made to this group was 76. Initially 30 valves were from VA type and the remaining 24 from VP type, but reintervention was needed in 15 and 11 respectively.

Solitary pelvic kidney and neuroblastoma in a child.

We describe a case of a solitary pelvic kidney coexisting with adrenal and pelvic neuroblastoma in a child with multiple malformations, including microcephaly, hypertelorism, aortic coarctation and a bifid uterus. The association of a solitary kidney and neuroblastoma has not been reported previously.

[Neonatal functional intestinal obstruction of unknown etiology (author's transl)].

Three cases of newborn intestinal obstruction without obvious organic cause are reported. Narrow left colon (Davis's syndrome), small colon, megacystis and intestinal hypoperistaltism (Berdon's syndrome) and segmental bowel dilatation (Swenson's syndrome) were the diagnoses. Through a review of the literature a possible interrelationship among these three clinical entities at the level of an abnormal myenteric plexus neuronal function is discussed.

[Primary acetabular protrusion (author's transl)].

A case of primary protrusion of the acetabulum in a ten year old girl, is presented. A review of the tiology, history, clinical signs and treatment is done. Authors comment the influence of genetic factor in the mother and the father, in the clinical picture of their patient.

[Blue rubber bleb nevus (author's transl)].

A case of Blue Rubber Bleb Nevus in a 11 year-old boy is reported. The patient exhibited characteristic hemangiomas of the skin and gastrointestinal tract with an iron deficiency anemia. Historical, clinical, pathological, and surgical features of the condition are discussed.

Immunological studies in the postsplenectomy syndrome.

Variations in the serial immunoglobulins of 52 children splenectomized for a variety of indications were studied and compared with two groups of children, one postoperative and one without operation. The most significant finding was the constant decrease in Ig M in every instance. Our series of splenectomized children seems to confirm the facts noted by other authors.
