Prevalence of HBsAg carriers in native and immigrant pregnant female populations in Israel and passive/active vaccination against HBV of newborns at risk.

Israel has no official prevention policy at present against perinatal and horizontal transmission of hepatitis B virus (HBV) infection in newborns and children at risk. The present study was designed to assess the prevalence of HBV carrier state in a population of 11,123 pregnant women at term. Among this population (mean age 29.7 +/- 5.9), 98 women (0.88%) were found to be asymptomatic HBsAg+ carriers, and 97% of these carriers were anti-HBe+. Evidence for HBV replication, as determined by serum HBV-DNA, was established in 6.6% of the HBsAg+/anti-HBe+ population. The HBsAg carrier rate was strongly influenced by religion, continent, and country of birth of the carrier mothers. The highest relative carrier rate was found among women of Moslem origin (4.3%), as compared to Jewish women (0.67%). Most carrier women were born in Israel (56.1%) to mothers who had emigrated from regions with intermediate or high endemicity of HBV, such as North Africa or the Middle East. In these groups, the HBsAg carrier rate ranged between 1.2 and 3.0%. Ninety-three percent of newborns receiving passive/active vaccination against HBV developed protective levels of anti-HBs. Finally, evidence for horizontal transmission of HBV was found in 19.3% of 83 non-vaccinated children in families of HBsAg carriers. The present study therefore establishes HBsAg prevalence rates in specific risk groups of women at term and confirms the need for an official policy on immunization against HBV in Israel. Since over 50% of women at term belong to the defined risk groups, universal active vaccination of the entire newborn population each year is suggested as the most rational and needed policy in Israel.

Subacute meningitis caused by Brucella: a diagnostic challenge.

A case of subacute meningitis caused by Brucella mellitensis is described. The meningitis was refractory to an antibiotic regime. Diagnosis was established by raised antibody titres to Brucella in serum and cerebrospinal fluid (CSF) and positive bone marrow and blood cultures. While treatment with tetracycline trimethoprim-sulfamethoxazole and streptomycin resulted in a dramatic clinical cure, the CSF findings returned only gradually to normal values over the ensuing 6 months.

Relationship between head dimensions and body length in the context of mental retardation.

The relationship and possible disproportion between different cranial dimensions--head length, head circumference and biparietal diameter--body length and developmental status in normocephalic children were studied in 166 mentally retarded and 471 normal control subjects, between the ages of 3 months and 6 years. When the total cohort was analyzed, all dimensions, particularly head length, were found to be significantly reduced in the study group compared with the controls. Stratification into three age-groups revealed that in the 3- to 15-month-old subjects, head length was the most significantly reduced dimension, while in the older children body length was more significant, followed by head length. Further discriminant analysis resulted in a formula consisting of only three factors--body length, head length and age. Head circumference and biparietal diameter were noncontributory. This investigation did not support the concept of a disproportionately small head compared with height in normocephalic mentally retarded children, but rather a general growth failure mostly affecting height and head length.

Muscle carnitine deficiency presenting as familial fatal cardiomyopathy.

Three siblings presented with fatal cardiomyopathy confirmed by electron microscopy, and normal serum but low muscle carnitine concentrations. A fourth had similar signs but remained asymptomatic. He was treated with carnitine orally which increased the concentration in muscle, though it remained below normal. Electron microscopic features were unchanged.

Angiography of azygos continuation of inferior vena cava in situs ambiguus with left isomerism (polysplenia syndrome).

We have in our records 11 patients with situs ambiguus and left isomerism (polysplenia). Ten had an interruption of the inferior vena cava (IVC) with azygos continuation; in eight cases the continuation was to the left superior vena cava (LSVC), in one case to the right superior vena cava (RSVC) and in one case to both the LSVC and RSVC. Two patients underwent surgical correction by a baffle procedure of the functioning single atrium. The angiographic confirmation of the azygos system anatomy is important in planning the surgical correction of patients with left isomerism. Clinically, given the same heart defects with normal pressures, the right-sided drainage is probably more favorable, producing less peripheral desaturation.

Malignant lymphoma associated with marked eosinophilia.

A 60-year-old black man with poorly differentiated lymphocytic lymphoma presented with generalized lymphadenopathy and marked eosinophilia. Extensive evaluation of the eosinophils revealed them to be normal morphologically and functionally. The patient responded to corticosteroid therapy with resolution of the lymphadenopathy and reversion of the peripheral blood counts to normal limits. Recurrence of the original clinical picture within months prompted institution of systemic chemotherapy. Response was transient, and the patient expired after an unremitting downhill course. Recent advances in our knowledge of mechanisms of eosinophilia and eosinophil function are reviewed. The relationship of lymphoma to eosinophilia is discussed.
