This cross sectional study was done to find the prevalence of sustained hypertension and prehypertension among school children aged 11-17 years. A total of 1085 apparently healthy students from rural and urban schools in hills of northern India were examined using standard methods. Students with blood pressures above the 90th centile were reexamined after four weeks. The mean BMI of the students was 17.5 ± 2.7 kg/m2, 5 (0.4%) were obese, and 39 (3.5%) overweight. After two evaluations, hypertension was identified in 62 (5.9%) children and prehypertension in 130 (12.3%). Urban and rural children had comparable rates of elevated BP (hypertension and prehypertension). Rates of elevated BP were significantly higher (46.5% vs 17%, P<0.001) among those with high BMI (overweight and obese) compared to those with normal BMI. In conclusion, nearly 20% of the school children had elevated blood pressures.

A total of 2063 live births were studied during one year period from July 1994 to June 1995. Neonatal mortality rate (NMR) was 35.4 per thousand live births. The case fatality rate among low birth weight and preterms was 10.1% and 18.1% respectively. Though, low birth weight babies accounted for 27.8% of the live births but contributed for 79.5% of neonatal deaths [p < 0.001]. Similarly, preterm babies accounted for 13.2% of the live births but contributed for 69.9% of neonatal deaths [p < 0.001]. The causes of neonatal deaths found were birth asphyxia (31.1%), infections (23.3%), immaturity (17.8%), hypothermia (9.6%), hyaline membrane disease (2.7%) and cogenital malformation (1.4%). There is need to identify strategies to reduce the incidence of prematurity and low birth weight babies. Comprehensive antenatal coverage and adequate care followed by optimal management of newborns at birth is likely to reduce NMR and improve quality of life among survivors.

In April 2016, an indigenous monovalent rotavirus vaccine (Rotavac) was introduced to the National Immunization Program in India. Hospital-based surveillance for acute gastroenteritis was conducted in five sentinel sites from 2012 to 2020 to monitor the vaccine impact on various genotypes and the reduction in rotavirus positivity at each site. Stool samples collected from children under 5 years of age hospitalized with diarrhea were tested for group A rotavirus using a commercial enzyme immunoassay, and rotavirus strains were characterized by RT-PCR. The proportion of diarrhea hospitalizations attributable to rotavirus at the five sites declined from a range of 56–29.4% in pre-vaccine years to 34–12% in post-vaccine years. G1P[8] was the predominant strain in the pre-vaccination period, and G3P[8] was the most common in the post-vaccination period. Circulating patterns varied throughout the study period, and increased proportions of mixed genotypes were detected in the post-vaccination phase. Continuous long-term surveillance is essential to understand the diversity and immuno-epidemiological effects of rotavirus vaccination.

Background: Rebound hyperbilirubinemia may occur after cessation of phototherapy in new-borns in certain high-risk situations. However, data regarding the phenomenon of bilirubin rebound is lacking from India. Aim was to study the incidence and associated risk factors of post phototherapy rebound hyperbilirubinemia.Methods: The study subjects included all neonates (gestation >34 weeks) admitted to newborn unit who required phototherapy for hyperbilirubinemia. Unit protocol based on American academy of pediatrics (AAP) guidelines were used to start and stop phototherapy. Rebound bilirubin was measured 24±6 hours after stopping phototherapy. Significant bilirubin rebound (SBR) was defined as post phototherapy bilirubin level needing reinstitution of phototherapy. The risk factors associated with significant rebound were studied.Results: Out of total 509 neonates who received phototherapy due to hyperbilirubinemia, 63 (12%) had significant bilirubin rebound requiring reinstitution of phototherapy. There was significant risk for rebound in neonates who had prematurity (p <0.01), ABO (<0.001) and Rh incompatibility (p<0.005) with mother, G6PD deficiency (p < 0.001) and onset of hyperbilirubinemia less than 72 hours of postnatal age (p< 0.001). However, neonates with extravasations of blood, polycythaemia, sepsis, other causes of haemolysis and idiopathic group did not have significant risk of developing rebound.Conclusions: Post phototherapy bilirubin estimation and follow up should be ensured in high-risk neonates.

During the study period there were 2063 live births. Of these 573 (27.8%) were low birth weight (LBW), 277 (13.4%) preterm and 148 (7.1%) small for date (SFD) babies. In all, 263 (12.7%) newborns suffered from one or the other morbidity. Birth asphyxia of varying severity developed in 130 (6.3%) babies [88 LBW and 42 normal birth weight (NBW) (p < 0.001)]. Respiratory distress syndrome was diagnosed in 82 (3.9%) babies, most being due to hyaline membrane diseases (31.7%), which affected 26 (9.4%) of preterm babies. Deep infections were seen in 109 (5.3%) newborns [60 LBW and 49 NBW, (p < 0.001)] and superficial infections were seen in 79 (3.8%) babies [46 LBW and 33 NBW, (p < 0.001)]. Hyperbilirubinemia was detected in 78 (3.8%) babies. In one fifth of the babies, the cause of hyperbilirubinemia remained unidentified even after detailed investigations. Hypothermia was observed in 59 (2.9%) newborns [48 LBW and 11 NBW, (p < 0.001] and congenital malformations were seen in 24 (1.7%) babies. Morbidity was found to be high amongst LBW and preterm babies. The incidence of deep infections and hypothermia was high in our study.
