This trial confirmed the immunogenicity of a standard dose of measles vaccine Edmonston-Zagreb strain administered at the age of 6 months as evaluated serologically at 12 months of age in 94 healthy children in Saudi Arabia. The residual seropositivity rate for measles was 53.4 and 80.6% as measured by enzyme immunoassay (EIA) and plaque neutralization, respectively, and could be increased to virtually 100% seroprotection after immunization with 1 of 2 measles-mumps-rubella (MMR) vaccines (Triviraten Berna or MMR II MSD) at 12 months of age. In both groups, more than 90% of infants showed an immune response to the mumps and rubella vaccine strains at 14 months of age. There was a difference in the geometric mean titres of mumps antibodies in favour of MMR II (P < 0.001). The seroconversion rates for mumps antibodies differed between the 2 vaccines because of the different test systems and/or the different cut-off levels used. The study reconfirmed that for the assessment of Rubini mumps vaccine-induced antibodies the indirect immunofluorescence test is superior to the EIA. The systemic tolerability of both vaccines was excellent. Triviraten Berna is exclusively propagated on human diploid cell cultures and hence free of avian proteins.

Fluconazole in the therapy of tropical deep mycoses.

A clinical study was conducted to test the efficacy of fluconazole in the treatment of tropical deep mycoses. Two out of four patients with zygomycosis due to Conidiobolus coronatus who were treated with the drug were completely cured; the other two patients exhibited considerable improvement but could not be followed up. Two patients with eumycetoma, one due to an Acremonium sp. and one due to Pseudallescheria boydii, were treated successfully, whereas another patient with a eumycetoma caused by an unidentified fungus could not be followed up. A complete cure was achieved with one patient with African histoplasmosis and one with candiduria. A case of cerebral phaeohyphomycosis due to Cladosporium sp. showed some improvement but the patient later developed meningitis and died.

Childhood diabetes in Saudi Arabia.

In Suleimania Children's Hospital, Riyadh, Saudi Arabia, 110 diabetic children were diagnosed and followed over a 5-year period (1985-1989). Seventy-five percent (82/110) were of Saudi origin and 54% (59/110) female. Their parents were often related, 31% (34/110) being first degree cousins, and 12% (13/110) second degree cousins. First degree family history was positive for Type 1 diabetes in 28% (31/110). Among these cases, siblings accounted for 26%, fathers 2%, and mothers none. Family history was also positive for Type 2 diabetes in 35% (38/110) and for both Type 1 diabetes and Type 2 diabetes in 14% (15/110). Mean age at onset was 5.9 years (7 months to 12 years). Thirty percent (33/110) of the patients were under 3 years of age on admission. The most common clinical presentation was diabetic ketoacidosis, seen in 67% of the patients (74/110).

Macrophagelike vacuolated renal tubular cells in the urine of a male with osmotic nephrosis associated with intravenous immunoglobulin therapy. A case report.

BACKGROUND: Osmotic nephrosis is a form of renal tubular injury that has been found in patients treated with intravenous immunoglobulin (IVIG). CASE: A 46-year-old male who had two courses of chemotherapy for acute myelogenous leukemia was found to have refractory thrombocytopenia. After IVIG (Sandoglobulin 12%, Novartis) administration (1 g/kg) for five consecutive days, the patient became oliguric and eventually anuric on the fifth dose. Hemodialysis was initiated, and urine production was noted on day 2 of hospitalization. Routine cytologic examination of fresh, voided urine showed numerous macrophagelike, bland epithelial cells with abundant, multivacuolated cytoplasm. Cytokeratin immunostain revealed positivity, thus confirming the epithelial origin of these cells. CONCLUSION: To our knowledge, this is the first such case reported in the English-language cytology literature. Awareness of a patient's clinical history may be helpful in avoiding an incorrect diagnosis. Urine cytology may be useful in obtaining an early diagnosis of osmotic nephrosis in patients receiving high-dose IVIG therapy that may eliminate the need for a renal biopsy.

Endothelins and their receptors in cirrhotic and neoplastic livers of Canadian and Chinese populations.

BACKGROUND: Endothelins (ETs) are 21 amino acid peptides with widespread tissue distribution and functions. In this study, we retrospectively investigated immunoreactive ET-1, ET-3 as well as ET receptors by ligand binding and autoradiography in hepatic cirrhosis and neoplasms. MATERIALS AND METHODS: Formalin fixed paraffin embedded tissues from 30 hepatocellular carcinomas (HCC), 4 fibrolamellar carcinomas (FLC), and 7 liver metastatic adenocarcinomas (Ad) from colon were collected from the Pathology Department of London Health Science Centre. Adjacent cirrhotic livers were obtained from 17 cases and adjacent normal liver was present in 12 cases. In addition, 15 HCCs, 6 cirrhotic and 8 normal livers were obtained from Normal Bethune University for Medical Sciences in China. The slides were stained for ET-1 and ET-3 with a polyclonal antibody and scored. Autoradiographic localization of ET-receptors with 125I-ET-1 was carried out in some of the cases. RESULTS: In the normal liver, hepatocytes, biliary epithelium, vascular endothelium and smooth muscle cells were positive for both ET-1 and ET-3. Higher immnunoreactivity for ET-1 and ET-3 was seen in cirrhosis. HCCs showed variation in immunoreactivity, with overall scoring not different from normal livers. FLCs showed consistent higher immunoreactivity for both ET-1 and ET-3, while in Ads the immunoreactivity was decreased. Increased ET-receptors, representing both ETA and ETB subtypes were seen in both cirrhosis and in HCC. CONCLUSION: Alterations in both ETs and their receptors were found in cirrhosis and neoplastic liver diseases.

Red cell membrane lipids in thalassaemia.

Red cell and plasma lipids and their fractions were estimated in 20 cases of thalassaemia and 20 normal controls. In thalassaemia there was reduction in red cell lipids and their fractions, plasma lipids and their fractions, and derangement of liver functions. On the other hand, the intestinal fat absorption, morphology of intestinal mucosa and histochemical studies of fat absorption were normal. Hypolipidaemia may be possibly caused by deranged liver functions and is probably responsible for the diminution in erythrocyte lipids. A genetic factor producing reduction in red cell lipids may be also present.

Study of red cell membrane lipids in glucose-6-phosphate dehydrogenase deficiency anemia.

Red cell membrane lipids and plasma lipids were studied in 20 patients with G.6.P.D. deficiency, during acute hemolysis and 45-60 days later-20 normal controls were similarly investigated. All lipids in G-6-P-D deficient cells were found to be diminished during the attack of hemolysis and to return back with the exception of lecithin to normal after recovery. Plasma cholesterol and phospholipids were markedly diminished during acute hemolysis, but slightly reduced on recovery.
