Clinico-radiological Observations in Meconium Aspiration Syndrome.

INTRODUCTION: To understand and report the prevalence of meconium aspiration syndrome and the clinico-radiological features in a tertiary care hospital of western Nepal. METHODS: An observational study carried out for a year in 2014-15 in all babies with MAS. Clinical and radiological profiles of MAS in relation to gender, gestational age, mode of delivery, birth weight, Apgar score, thickness of meconium, age at admission and the immediate outcome were studied. RESULTS: Out of 584 admitted newborns (male=389; female=186) during the study period, 78 (13.4%) had meconium aspiration syndrome with male: female ratio of 1.2:1. Majority of babies admitted to NICU had thick meconium [n=52 (66.7%)]. There was no statistical significant difference in various parameters such as Apgar score at 1 and 5 minutes, respiratory distress, birth asphyxia, duration of oxygen use, MAS severity and chest x-ray in those with thick MAS compared to thin. Among all newborns with MAS, 59% (n=46) had abnormal radiological findings with over two-folds in those with thick MAS (71.7%)] compared to thin (28%). Hyperinflation (47.8%), diffuse patchy infiltration (37%), consolidation (21.7%) collapse (8.7%), right lung fissure (6.5%) and pneumothorax (8.7%) were the abnormal radiological findings seen in MAS babies. The odds of having APGAR score at 1 minute at least 7 or more was twice unlikely in those having thick meconium compared to thin (P=0.02) Conclusions: Thick meconium is relatively common with more significant abnormal radiological findings and low Apgar score.

Neurocysticercosis in Children with Seizures: A Cross-Sectional Study.

BACKGROUND: Neurocysticercosis (NCC), a common cause of seizures in children from low and middle income countries (LMICs), if not diagnosed and treated early enough may lead to considerable morbidity and mortality. There is a lack of data on the prevalence of NCC and its clinical characteristics among those with seizure in South-Western Nepal. AIMS AND OBJECTIVES: To study the prevalence and clinical characteristics of NCC in children with seizures. MATERIAL AND METHODS: All children admitted to Universal College of Medical Sciences, a tertiary hospital in South-Western Nepal with seizures during 2014-16, were tested for NCC. NCC was diagnosed by neuroimaging [computerized tomography (CT) scan or magnetic resonance imaging (MRI)]. We used logistic regression to test the association between NCC with participants' characteristics and clinical symptoms. RESULTS: Among 4962 in-patient children, 168 (104 boys and 64 girls) had seizures (138 with generalized tonic clonic seizures (GTCS) and 30 with focal seizures). 43% of children with seizures had CT scan confirmed NCC. The prevalence of NCC in the oldest children (13-16 years) was significantly greater (57.1% versus 15.6%) compared to the youngest (0-4 years) one (p < 0.001). Among 72 children with NCC, the proportions of children with vesicular, calcified, and colloidal stages were 76% (n = 35), 18% (n = 13), and 6% (n = 2), respectively. Children with focal seizures had 13% more NCC compared to those with GTCS but the result was statistically not significant. The adjusted odds of having NCC among 5-8 years, 9-12 years, and 13-16 years children were 6.6 (1.78-24.60), 11.06 (2.74-44.60), and 14.47 (3.13-66.96), respectively, compared to 0-4-year-old children. Reoccurrence of seizures within the first 3 months of taking antiepileptic drug in those with NCC was approximately 3 times higher compared to those without NCC (11% versus 4%, p = 0.084). CONCLUSIONS: This study shows that NCC contributes significantly to higher prevalence of seizures in children in South-Western region of Nepal.

Gestational Age Specific Postnatal Growth Curves for Singleton Babies in A Tertiary Hospital of Western Nepal.

INTRODUCTION: Measurement of birth weight, crown-heel length, head circumference and chest circumference used to assess the intrauterine growth of a baby vary with altitude, race, gender, socioeconomic status, maternal size, and maternal diseases. The study aimed to construct centile charts for birth weight, crown-heel length and head circumference for new born at different gestational ages in Western Nepal. METHODS: This was a descriptive cross-sectional study done over a period of 15 months in a tertiary care hospital of Western Nepal. Birth weight, length, head circumference and chest circumference were measured within 12-24 hours of birth. Gestational age was estimated from the first day of last menstrual period and New Ballard's scoring system. Microsoft 2007 Excel and SPSS-16 was used for data analysis. Cole's Lambda Mu Sigma method was used for constructing centile curves. RESULTS: Out of 2000 babies analysed, 1910 samples were used to construct smoothed intrauterine growth curve of birth weight, crown-heel length, and head circumference from 33-42 weeks of gestation. Among all, 1147 (57.35%) were male and 853 (42.65%) were female, mean gestational age was 38.13±2.44 weeks. The means of birth weight, crown-heel length, head and chest circumference were 2744.78 gm, 47.80 cm, 33.18 cm, and 30.20 cm with standard deviations of 528.29, 3.124, 1.78, and 2.35 respectively. CONCLUSIONS: This necessitates the update in the existing growth charts and development in different geographical regions of a country.

Relationship of exclusive breast feeding for 6 mo to linear growth up to 18 mo of age.

OBJECTIVE: To assess if linear growth in infant is optimal, with exclusive breast feeding for 6 mo as advised by the WHO. METHODS: This prospective follow up study included 71 full term babies of middle socio economic group healthy mothers. The mothers were instructed to breast feed the babies who were followed up to 18 mo of age for assessment of linear growth. The study was conducted in Metro General Hospital, Noida, U.P. Fifty six babies weighed ≥ 2.5 kg, and 15 babies weighed <2.5 kg at birth. The main outcome measure was linear growth in exclusively breast fed infants. RESULTS: At 18 mo, infants ≥ 2.5 kg on exclusive breast feeding for <6 mo and receiving semisolids early gained more length by 3.4 cm than those receiving breast feeding for ≥6 mo, and infant <2.5 kg gained more weight by 1.2 kg. CONCLUSION: For infants ≥ 2.5 kg of middle socioeconomic group, exclusive breast feed for 6 mo seems sufficient for optimal growth as compared to standard and reference growth data.

Dietary intake and growth pattern of children 9-36 months of age in an urban slum in Delhi.

This investigation deals with the dietary intakes and growth in early childhood in poor communities. Five hundred and forty five children, 9-36 months of age, and their caretakers (mothers) were selected randomly and invited to participate in the study. The food and nutrient intake of children was assessed using a 10-item food frequency and amount questionnaire (FAQ). The anthropometric nutritional status was assessed by the indices height-for-age (H/A), weight-for-age (W/A), weight-for-height (Wt/Ht) and MUAC, according to Indian and NCHS standards. The results showed that the intake of cereals, pulses, roots, green leafy vegetables (GLVs), other vegetables, fruits, sugar, fats and oils among children was grossly inadequate. The nutrient intake for energy was 56% of the current RDA. Anthropometric analysis revealed that the children were grossly undernourished. Seventy five per cent children were underweight (<-2 SD), while 35% severely undernourished (<-3 SD). Approximately, 74% children were having short stature (chronic malnutrition) with 39% severely stunted. Nineteen per cent children were excessively thin (wasted). The data regarding the degree of malnutrition among children demonstrated that 9.6% girls in 9-36 months of age had severe malnutrition as compared to 6.5% males. The maximum prevalence of severe malnutrition was in the age 31-36 months (10%) followed by 9.6% in 13-18 months. The moderate degree of malnutrition was around 30 to 33% in age group 13-36 months. The evidence from the study provides a strong basis to suggest low food intake as the main cause of under/malnutrition and growth retardation (stunting) in early childhood in poor communities.

Effect of latent iron deficiency on GABA and glutamate neuroreceptors in rat brain.

Eight weeks of latent iron deficiency in weaned female rats of Sprague Dawley strain maintained on experimental low-iron diet (18-20 mg/kg) did not significantly change the gross body, weight and tissue weights of brain and liver. Packed cell volume (PCV) and hemoglobin concentration remained unaltered. However, non-heme iron content in liver and brain decreased significantly (p<0.001). The activities of glutamate dehydrogenase, glutamic acid decarboxylase, and GABA-transaminase (GABA-T) in brain decreased by 15%, 11.4% and 25.7% respectively. However, this decrease was not statistically significant. Binding of(3)H Muscimol at pH 7.5 and 1 mg protein/assay increased by 143% (p<0.001) in synaptic vesicular membranes from iron-deficient rats as compared to the controls.(3)H glutamate binding to the synaptic vesicles was also carried out under similar condition. However, the L-glutamate binding was reduced by 63% in the vesicular membranes of iron deficient animals. These studies indicate that iron plays important functional role in both excitatory and inhibitory neurotransmitter receptors.

Nutritional anemia and its control.

Available studies on prevalence of nutritional anemia in India show that 65% infant and toddlers, 60% 1-6 years of age, 88% adolescent girls (3.3% had hemoglobin < 7.0 g/dl; severe anemia) and 85% pregnant women (9.9% having severe anemia) were anemic. The prevalence of anemia was marginally higher in lactating women as compared to pregnancy. The commonest is iron deficiency anemia. National programmes to control and prevent anemia have not been successful. Experiences from other countries in controlling moderately-severe anemia guide to adopt long-term measures i.e. fortification of food items like milk, cereal, sugar, salt with iron. Use of iron utensils in boiling milk, cooking vegetables etc may contribute significant amount of dietary iron. Nutrition education to improve dietary intakes in family for receiving needed macro/micro nutrients as protein, iron and vitamins like folic acid, B12, A and C etc. for hemoglobin synthesis is important. As an immediate measure medicinal iron is necessary to control anemia. Addition of folate with iron controls anemia and is neuroprotective. Evidence in early childhood suggests vitamin B12 deficiency anemia; thus it may also be given along with iron and folate.
