Child's homocysteine concentration at 2 years is influenced by pregnancy vitamin B12 and folate status.

Longitudinal studies investigating vitamin B12 and folate status of mothers and their offspring will provide a better understanding of intergenerational nutrition. During pregnancy and 2 years (2y) after delivery, we measured plasma vitamin B12 and folate concentrations in 118 women [aged (mean ± s.d.) 22.9 ± 3.9y] who attended a rural (n = 68) or an urban (n = 50) antenatal clinic in Pune, India. Cord blood vitamin B12 and folate were measured, and when the child was 2y total homocysteine (tHcy) was also measured. Demographic and diet measurements were recorded using standard methods. Pregnancy plasma vitamin B12 concentration at 34 weeks was low [median (25th, 75th), 115 (95, 147) pm]; 75% had low status (<150 pm). Plasma folate was high (mean ± s.d., 33 ± 21 nm); one had a folate concentration <7 pm. Cord plasma vitamin B12 and folate concentrations were higher than and positively associated with maternal concentrations. In stepwise regression, higher child vitamin B12 at 2y was predicted (total R 2 15.7%) by pregnancy vitamin B12 (std ß 0.201, R 2 7.7%), current consumption of cow's milk (std ß 0.194, R 2 3.3%) and whether breast feeding was stopped before 2y (std ß -0.234 R 2 7.2%). Child's 2y tHcy concentration was high (11.4 ± 3.6 µm) and predicted by lower pregnancy vitamin B12 (std ß -0.206, R 2 4.1%), lack of vitamin supplementation (std ß -0.256, R 2 5.6%) in pregnancy and whether currently breastfed (std ß 0.268, R 2 8.4%). Low maternal vitamin B12 status in pregnancy and prolonged breast-feeding results in disturbed one-carbon metabolism in offspring at 2y. Supplementation of women of child-bearing age, particularly during pregnancy and lactation, may improve the homocysteine status of these children.

Internal iliac artery ligation for arresting postpartum haemorrhage.

OBJECTIVE: To study the role of internal iliac artery ligation (IIAL) in arresting and preventing postpartum haemorrhage (PPH). DESIGN: Retrospective chart review of women undergoing therapeutic IIAL for PPH or prophylactic IIAL for risk of PPH. SETTING: Tertiary care hospital in Pune, India. SAMPLE: Women admitted to King Edward Memorial (KEM) Hospital, Pune, India, who underwent IIAL to control or prevent PPH. METHODS: Bilateral IIAL was performed in all women. MAIN OUTCOME MEASURES: Need for re-laparotomy or hysterectomy to control haemorrhage, complications of the procedure. RESULTS: Out of 110 women who underwent IIAL, 88 had therapeutic IIAL for PPH from atony (36), genital tract injury (23), placenta praevia (21), placental abruption (4), uterine inversion (3) or coagulopathy (1). Hysterectomy was performed after IIAL failed to arrest haemorrhage in 33 (39.3%) of 84 women (excluding 4 with vaginal lacerations). Hysterectomy was more likely with uterine rupture (79%) than with nontraumatic PPH (up to 27%). Failure to control haemorrhage by IIAL was evident immediately, and bleeding arrested by IIAL did not recur to require later laparotomy in any woman. Out of 22 women at high risk for PPH undergoing prophylactic IIAL at caesarean section, none had subsequent haemorrhage. One woman had an iliac vein injury that was repaired with no further morbidity. There were no ischaemic complications either during inpatient stay or up to 6 weeks. CONCLUSIONS: IIAL is useful in the treatment and prevention of PPH from any cause. Early resort to IIAL effectively prevents hysterectomy in women with atonic PPH. In traumatic PPH, IIAL facilitates hysterectomy or repair as indicated and prevents reactionary haemorrhage.

Single high dose of intravenous phenytoin sodium for the treatment of eclampsia.

Phenytoin sodium was administered intravenously as a single 900 mg dose in 33 consecutive women with eclampsia immediately on admission. No untoward effects were observed either in the mother or subsequently in the neonate. Since the patient's level of consciousness is unaltered by the drug, it could be monitored serially as part of neurological assessment. The risks of pulmonary aspiration, respiratory depression and airway obstruction arising from deep sedation which occurs with standard regimens, were averted. Control of convulsions was adequate without the need for any complicated drug related patient monitoring.
