✓ Adult dogs were rendered hydrocephalic by the injection of kaolin into the cisterna magna. One group of dogs was sacrificed 1 month after kaolin administration, and ventriculojugular shunts were performed on the other group. Hydrocephalic dogs with shunts were sacrificed 1 day or 1 week after the shunting procedure. All dogs were perfused with formalin at physiological pressure, and the brain stem and cervical spinal cord were examined by light microscopy. Subarachnoid granulomata encompassed the superior cervical spinal cord and dependent surface of the brain stem. Rarefaction of the posterior white columns and clefts or cavities involving the gray matter posterior to the central canal and/or posterior white columns were present in the spinal cords of both hydrocephalic and shunted hydrocephalic dogs. Predominantly in the dogs with shunts, hemorrhages were noted in the spinal cord in association with the clefts or cavities. A mechanism of ischemia followed by reflow of blood is postulated to explain the hemorrhages in the spinal cords of hydrocephalic dogs with shunts.

✓ The authors report a case of pineoblastoma with a 9-year follow-up period after stereotaxic biopsy, a shunting procedure, and radiotherapy. Light and electron microscopic studies of biopsy and autopsy specimens revealed no cell differentiation of the pineoblastoma. The possible factors predisposing to long survival are discussed in comparison with the course in patients with medulloblastoma.

✓ A patient with postinflammatory hydrocephalus had a multiloculated, lateral ventricular system that was treated by a routine shunting procedure after the multiloculated system had been converted into a uniloculated system by direct intraventricular surgery.

✓ The authors describe a T-tube Silastic shunting device which has been used for lumboperitoneal shunting in 62 patients with communicating hydrocephalus during the past 3 years. In 38 patients it was inserted as a primary shunting procedure; 24 patients had the shunt inserted following problems secondary to arachnoiditis created by a polyethylene-type lumboperitoneal shunt. The shunt described here has not led to arachnoiditis when inserted as a primary shunting procedure. In 61% of patients no operative revisions of their shunt has been required to date, and 81% continue to do well on their T-tube type shunt.

The technique of cross circulation was used to study antihemophilic factor ( AHF) in normal and hemophilic dogs. Following cross circulation of 60 min, the plasma AHF of the hemophilic animals had increased to about 50% of the normal level. This increase was not accompanied by a corresponding decrease in the AHF in the plasma of the normal dog. In other experiments, splenectomized normal dogs were cross circulated with hemophilic dogs. Without a spleen, the normal dog was unable to maintain its plasma AHF during the shunting procedure. These studies indicate that the spleen is important in the homeostasis of antihemophilic factor.

SUMMARYA 76 year old patient with a long history of headaches was found to have Paget’s disease and communicating hydrocephalus. There were (otherwise) no neurological or musculo-skeletal manifestations of Paget’s disease, but moderate impairment of intellectual function was present. Treatment with disphosphonates did not bring any significant improvement, but three days following a ventriculo-atrial shunting procedure, the patient became headache-free for the first time in several years.In the literature, patients with hydrocephalus have been shown to respond quite unevenly to atrio-ventricular shunting, but in most instances the descriptions concerned advanced cases with well-established symptoms of dementia, ataxia and incontinence. Our case is reported to stress the importance of early diagnosis and management of hydrocephalus in Paget’s disease for the prevention of widespread neurological dysfunction.

Abstract Fifty-five patients with liver disease of varied etiology and severity have been studied. Serum folate concentrations were subnormal and folic acid clearances rapid, when studied, in 19 actively imbibing alcoholic cirrhotics who had a megaloblastic anemia. Eleven patients, from both the nonalcoholic and alcoholic groups, had rapid folic acid clearances, with subnormal serum folate levels in seven, in the absence of morphologic evidence of folate deficiency. Serum B12 concentrations were uniformly normal or elevated. Dietary deficiency appeared to be the major cause of folate deficiency; all 19 patients who had megaloblastic changes were considered to have an inadequate dietary intake. Increased requirement for folate due to hyperactivity of the bone marrow secondary to gastrointestinal bleeding. hypersplenism, or hemolysis appeared to contribute to the development of abnormal folic acid determinations in many patients in both the alcoholic and nonalcoholic groups. Two of 10 patients studied had malabsorption of folic acid. Such factors as the presence of ascites, an expanded plasma volume, a Patent portacaval shunting procedure, the type of alcoholic beverage imbibed, and the severity of impairment of liver function did not appear to be of significance in the development of folate deficiency.
