Immunoglobulin G and complement C3 levels in pregnancy induced hypertension.

The immunoglobulin G (IgG) and complement C3 (C3) were measured in the maternal as well cord blood sera of 30 cases of pregnancy induced hypertension (PIH) as well as 9 controls with normotensive pregnancy. A depression of IgG as well as C3 level was observed in the maternal as well as cord sera of the mothers with PIH. These findings suggest decreased immunological status of both mother and her offspring in PIH, irrespective of the gestation and intrauterine growth status.

Congenital malformations at birth.

Three thousand nine hundred and thirty-two consecutive newborns were examined at birth for the presence of congenital malformations. The overall incidence of malformations was 1.2%. Congenital malformations accounted for 9.2% of perinatal and 12.8% of neonatal deaths. The central nervous system (39.5%) was most commonly involved followed by musculoskeletal system (14.5%). Involvement of more than one system was observed in 18.8% cases. Though there was higher incidence of malformations in babies born to mothers of more than 35 years the difference was not statistically significant. However, the babies born to mothers of gravidity 4 or more had significantly higher incidence of malformation when compared to mothers of lower gravidity (chi1(2) = 4.67, p < 0.05). The incidence of congenital malformations at birth was higher in stillborn and low birthweight babies.

Maternal hemoglobin and serum albumin and fetal growth.

Four hundred and eighty four pregnant women and their offsprings were studied to determine the relationship of maternal hemoglobin and serum protein levels on the birthweight of offspring. The correlation coefficient of maternal hemoglobin as well as serum albumin level (gamma = 0.1097 and 0.0936, respectively) with birthweight were not statistically significant. However, mean birthweight of neonates born to nonanemic mothers was significantly higher than of those born to anemic mothers. The prevalence of low birthweight babies was significantly higher among anemic mothers (p < 0.01); however, no such trend was observed in relation to maternal serum albumin (p > 0.05).

Audit in maternal and child health.

Audit in medicine is a well tried means of assessing the quality of practice by using acceptable measures of outcome. Audit in maternal and child health has been limited to fatal outcomes such as maternal and perinatal deaths. The outcome of audit is of interest to the providers, the health authorities and the consumers. The utility of audit lies in effective use of data to improve quality of service. Quality control of instruments and education of junior staff are some other benefits of audit. The limitations of manpower, money, means, fear of litigation and above all dislike of clinicians for handling data are hurdles in the way of effective audit. The concept of 'Standard Primipara' and 'Total Fetal Wastage' are likely to add new dimension to perinatal audit.

Maternal and perinatal mortality due to eclampsia.

Forty-four mothers with eclampsia and their newborns managed during the year 1988 at the University Hospital of Banaras Hindu University, Varanasi were analyzed. The incidence of eclampsia was 2.2% of all hospital deliveries. Eclampsia was more common in women (below 20 years) and at gestation of 36 weeks and below, and amongst the mothers deprived of antenatal care. The maternal mortality amongst cases of eclampsia was 31.8% and perinatal loss was 38.6%. A relatively high incidence of eclampsia and maternal and perinatal loss was considered to be related to lack of antenatal care and late referral to the hospital. Our findings suggest that more frequent use of properly timed cesarean section can improve the maternal outcome.

The effect of systemic therapy on local-regional control in locally advanced breast cancer.

One hundred and seven patients with locally advanced breast cancer were prospectively referred for multimodality treatment on protocol using chemohormonal therapy to maximal response followed by local treatment and maintenance therapy. Forty-eight patients (45%) were diagnosed with Stage IIIA disease, 46 (43%) with Stage IIIB inflammatory cancer, and 13 (12%) with Stage IIIB non-inflammatory disease. Induction therapy consisted of cyclophosphamide, doxorubicin, methotrexate, and 5-fluorouracil with hormonal synchronization using tamoxifen and conjugated estrogens. Local treatment was determined by response to chemotherapy. Patients with a clinical parital response underwent mastectomy followed by local-regional radiotherapy while patients with a clinical complete response were biopsied for pathologic correlation. Those with residual disease received mastectomy followed by radiotherapy while those with a pathologic complete response received radiation only to the intact breast and regional nodes. With a median follow-up of 64 months, patients with IIIA disease had a significantly lower local-regional failure rate compared to IIIB inflammatory patients, with the 5-year actuarial local-regional failure rate as only site of first failure 3% for IIIA disease versus 21% for IIIB inflammatory cancer (p = .02), and local-regional failure as any component of first failure 12% versus 36% (p = .01), respectively. When local-regional failure was analyzed by repeat biopsy, 5/31 (16%) patients with a pathologic complete response treated with radiation only developed a local-regional failure versus 2/53 (4%) with residual disease treated with mastectomy and postoperative radiotherapy. The 5-year actuarial local-regional failure rate as first site of failure was 23% for radiation only versus 5% for mastectomy and post-operative radiotherapy (p = .07). The response to chemotherapy did not reliably predict local-regional control. Both relapse-free survival and overall survival were significantly better for IIIA versus IIIB patients; stratification by repeat biopsy did not however, significantly affect either relapse-free or overall survival.

Temporal and spatial modulation of a cytoskeletal antigen during peripheral axonal pathfinding.

A neuron-specific cytoskeletal antigen (5E10), whose expression pattern during initial motoneuron outgrowth into the chick limb suggests that it is playing a role in axon guidance, is described. This antigen, which was shown to be a phosphorylated epitope, probably of the intermediate weight neurofilament protein (NF-M), exhibits a highly stereotyped and spatially heterogeneous pattern of expression. The point of onset of expression, which was abrupt and occurred in the distal axon and base of the growth cone, differed between groups of neurons that projected to different targets. Specifically, expression occurred from positions where previous perturbation experiments suggested that the axons in question would begin responding to specific guidance cues, and it remained high along the axon from this point to the target. Expression of this antigen could also be induced in cultured motoneurons by activating several second messenger systems.
