Effect of Dietary Fat Supplementation during Late Pregnancy and First Six Months of Lactation on Maternal and Infant Vitamin A Status in Rural Bangladesh.

Dietary fat intake is extremely low in most communities with vitamin A deficiency. However, its role in vitamin A status of pregnant and lactating women is poorly understood. The aim of the study was to examine the effect of supplementing women with fat from mid-/late pregnancy until six months postpartum on their vitamin A status and that of their infants. Women recruited at 5-7 months of gestation were supplemented daily with 20 mL of soybean-oil (n=248) until six months postpartum or received no supplement (n=251). Dietary fat intake was assessed by 24-hour dietary recall at enrollment and at 1, 3 and 6 months postpartum. Concentrations of maternal plasma retinol, β-carotene, and lutein were measured at enrollment and at 1, 3 and 6 months postpartum, and those of infants at six months postpartum. Concentration of breastmilk retinol was measured at 1, 3 and 6 months postpartum. The change in concentration of plasma retinol at three months postpartum compared to pregnancy was significantly higher in the supplemented compared to the control women (+0.04 vs -0.07 μmol/L respectively; p<0.05). Concentrations of plasma β-carotene and lutein declined in both the groups during the postpartum period but the decline was significantly less in the supplemented than in the control women at one month (β-carotene -0.07 vs -0.13 μmol/L, p<0.05); lutein -0.26 vs -0.49 μmol/L, p<0.05) and three months (β-carotene -0.04 vs -0.08 μmol/L, p<0.05; lutein -0.31 vs -0.47 μmol/L, p<0.05). Concentration of breastmilk retinol was also significantly greater in the supplemented group at three months postpartum than in the controls (0.68±0.35 vs 0.55±0.34 μmol/L respectively, p<0.03). Concentrations of infants’ plasma retinol, β-carotene, and lutein, measured at six months of age, did not differ between the groups. Fat supplementation during pregnancy and lactation in women with a very low intake of dietary fat has beneficial effects on maternal postpartum vitamin A status.

Cutaneous lesions in new born.

Five hundred unselected newborn babies delivered in the Department of Obstetrics and Gynaecology, Unit II of SGBT Hospital attached to Government Medical College, Amritsar during April 2000 to October 2000 were examined for cutaneous lesions daily for the first five days after birth. Different cutaneous lesions were seen in 474(94.8%) newborns. The physiological skin changes observed in order of frequency were Epstein pearls in 305(61%), Mongolian spot in 301(60.2%), superficial cutaneous desquamation in 200(40%), icterus in 128(25.6%), milia in 119(23.8%), sebaceous gland hyperplasia in 107(21.4%), occipital alopecia in 94(18.8%), lanugo in 72(14.4%), peripheral cyanosis in 47(9.4%), breast hypertrophy in 29(5.8%) and miniature puberty in 28(5.6%) newborns. Of the transient non-infective skin diseases, erythema toxicum neonatorum was observed most commonly in 105(21%), followed by miliaria rubra in 103(20.6%) and acne neonatorum in 27(5.4%) newborns. The naevi and other developmental defects in the descending order were salmon patch in 69(13.8%), congenital melanocytic noevi in 10(2%), accessory tragi in 3(0.6%), spina bifida in 2(0.4%), hydrocephalus in 1(0.2%) and poliosis in 1(0.2%) newborns. Cradle cap was the only dermatitis observed in 50(10%) newborns. One (0.2%) case each of Harlequin ichthyosis and labial cyst was seen.

Cytological evaluation of conjunctival scrape smears in cases of conjunctivitis.

The present study was conducted on 130 cases of untreated conjunctivitis and 25 control cases to assess the diagnostic value of cytology. Conjunctival scrapings from all cases were stained with Giemsa and Papanicoloau's stain and categorized cytologically and later correlated with the clinical profile. Normal cytologic profile was obtained in 7 cases (5.4%) of the study group and 14 cases (56%) of the control group. Cytologic diagnosis of trachoma was made in 63 cases (48.5%) including 48 out of 51 clinically diagnosed cases of trachoma, 9 cases of allergic conjunctivitis and 6 cases of acute follicular conjunctivitis, positive clinico cytologic correlation being 76.2%. Mucopurulent conjunctivitis was diagnosed in 24 cases (18.5%) both clinically as well as by cytological technique. Viral conjunctivitis was diagnosed in 24 cases (18.5%) including 19 cases (14.6%) of clinically diagnosed viral conjunctivitis and 5 cases (3.9%) of acute follicular conjunctivitis, positive correlation being 79.2%. Only 2 cases (1.5%) out of 15 clinically diagnosed cases of allergic conjunctivitis were confirmed cytologically. In all the 4 cases (3.1%) of spring catarrh and 6 cases (4.6%) of phlyctenular conjunctivitis the cytologic features were found to be consistent with the clinical diagnosis.

Immunization coverage evaluation surveys in rural Narela zone and city zone areas of Delhi.

A major purpose of the immunization coverage evaluation surveys to document the vaccination status of children aged 1-2 years was to determine the true picture of the immunization status of the target population and to identify areas which need strengthening. Immunization coverage evaluation surveys were carried out for a 2.4 lakh rural and 2.2 lakh urban population of Delhi by the cluster sampling method. A total of 210 and 212 children, respectively aged 12 to 23 months, were included in the study in 30 randomly selected clusters in each zone. The percentage of children immunized with DPT3/OPV3/BCG was 70.0 and 73.1 in the rural and city zones, respectively while those immunized with DPT3/OPV3/BCG/Measles was only 30.0 and 37.3% in the two zones. Dropout rate for DPT and OPV, I to III was 16-18%. The drop out rate between DPT and OPV II and III was higher than that between DPT and OPV II and II. Percentage of non-immunized children was significantly higher in rural (8.0%) as compared to urban areas (2.3%). Maximum immunizations were done by the Health Centres. Done on a periodic basis, a coverage evaluation survey will show whether or not vaccination coverage objectives have been met.
