Study to evaluate the relation between weight gain in infants and occurrence of retinopathy of prematurity

Purpose: Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Capturing serial daily postnatal weight gain can act as an innovative, low?cost method of risk stratification. We aim to study the relation between weight gain in infants and occurrence of ROP. Methods: The prospective, observational study was conducted on 62 infants. ROP screening was done based on the Rashtriya Bal Swasthya Karyakram (RBSK) criteria. Infants were classified into no ROP (n = 28), mild ROP (n = 8), and treatable ROP (n = 26) groups. Average daily postnatal weight gain was measured and its relation to development of ROP was studied. All statistical calculations were done using Statistical Package for the Social Sciences (SPSS) 21 version (SPSS Inc., Chicago, IL, USA) statistical program for Microsoft Windows. Results: Mean rate of weight gain in no ROP group, mild ROP group, and treatable ROP group was 33.12, 27.19, and 15.31 g/day, respectively (P = 0.001). Mean gestational age and birth weight in treatable group (n = 26) were 31.38 weeks and 1572.31 g, respectively. Receiver operating curve analysis revealed a cutoff of 29.33 g/day for ROP and 21.91 g/day for severe ROP. Conclusion: We concluded that, babies with poor weight gain of below 29.33 g/day are at high risk for ROP and babies with wight gain of 21.91 g/day are at high risk for severe ROP. These babies should be followed meticulously. So, the rate of weight gain of a preterm can help us to prioritize babies.

Hepatitis B virus and hepatitis C virus co-infection among outdoor patients and indoor patients of tertiary care institute, Bathinda, Punjab, India

Background: Hepatitis virus infections have many serious consequences like chronic hepatitis, fulminant hepatitis, liver cirrhosis, hepatocellular carcinoma and liver cancer. Serological test is thus necessary to identify hepatitis virus in the body. An observational study was conducted with an objective to detect hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (HCV) antibodies by rapid card tests and to find the prevalence of co-infection with hepatitis B and hepatitis C viruses from January 2019 to June 2019.Methods: Blood samples were received from patients irrespective of age and sex, constituted the material for the present study. All samples were tested on hepacard and tri-dot card for the detection of hepatitis B virus and hepatitis C virus and results were interpreted as per Clinical Laboratory Standards Institute guidelines.Results: Out of 3488 samples, 254 samples were positive for hepatitis virus infection. Out of these 254 samples positive for hepatitis viruses, 22 (0.6%) patients were positive for hepatitis B virus and 232 (6.6%) patients were positive for hepatitis C virus. Only 2 (0.7%) of these patients showed co-infection with both viruses.Conclusions: Male patients showed more positivity of hepatitis virus as compared to females. Patients were more from outpatient department (OPD) as compared to inpatient department (IPD). Hepatitis virus infection was found to be highest in the age group 21-40 and lowest in the age group above 80 years. Both the co-infected patients were males and from IPD.

Comparative study of seasonal variability in peak expiratory flow rate amongst school children in rural and urban areas

Background: Peak Expiratory Flow (PEF) is a value test for lung function and can be conveniently measured by using relatively inexpensive and portable Peak Flow Meter, identifying and assessing the degree of airflow limitation of individuals. While PEFR is obviously related to factors like age, weight, height, race, gender, it may also be additionally affected by seasons and climate. The purpose of study being to observe seasonal variation in PEFR amongst school going children and to observe peak expiratory flow rate in school going children in urban and rural areas.Methods: This prospective and comparative study was carried out on total 600 children; with 300 each from rural and urban schools, of age group 10-14 years, both sexes. Peak expiratory flow meter was used for the measurements in the seasons of summer (April to June) and winter (December to February) of the year. The results thus obtained were compiled and analysed.Results: The mean PEFR value (Litres/min) during summers in the rural children was 243.50(S.D.=16.050) while during winters was 253.63(S.D.=16.934), highly significant (p<0.001); mean PEFR summers in the urban children was 241.50(S.D.=20.530)and during winters was 249.93(S.D.=21.685), again highly significant (p<0.001).In both rural and urban groups PEFR values increased with increase in height and weight of the children which was found to be highly significant (p<0.001). Girls representation proportion in rural vs urban schools being 49% vs 45%; whereas boys being 51% vs 55% respectively.Conclusions: Peak expiratory flow rate decreased during summer season of the year in both rural and urban school attending children. In both the groups PEFR values had a direct correlation with height and weight of the children. Rural schools showed more girl student representation than their urban counterparts indicating more awareness for girl child education amongst rural population.

Conclusion: Quality-of-life improves more in patients taking benzoyl peroxide 2.5% gel and clindamycin 1% gel, and then, tretinoin 0.025% and clindamycin 1% gel and then benzoyl peroxide 2.5% gel and nadifloxacin 1% cream.

Detection of fetal malnutrition using “CAN score”.

Objective. Use of clinical assessment of nutrition status (CAN) score to assess the prevalence of fetal malnutrition among term newborns and to compare other anthropometric criteria used to assess fetal growth. Methods. Prospective study of 529 term healthy newborns assessed using CAN score .Complete anthropometric assessment and determination of weight for gestation was done. Using CAN score as a standard, the usefulness of birth weight, weight for gestation, length, head circumference (HC), mid arm circumference (MAC), MAC/HC ratio and Ponderal index to assess fetal nutrition was determined. Results. With a cut off value of 25, CAN score identified 148 (27.97%) malnourished neonates. 4% of appropriate for gestational age neonate were malnourished and 42.9 % of small for gestational age neonates were well nourished. When CAN score was taken as a standard, weight for gestation and MAC/HC had the highest sensitivity to identify malnourished neonates (92.5% & 90.5%). Conclusion. CAN score identifies malnourished neonates which can be missed by other methods and identifies well nourished neonates classified as growth retarded by other methods.

Indoor Radon measures have been carried out in the dwellings of Muktsar and Ferozepur districts of punjab using LR-115 plastic track detectors. Indoor Radon values ranged from 95 to 226 bq m(-3) and 75 to 233 bq m(-3) for winter season and 61 to 129 bq m(-3) and 79 to 138 bq m(-3) for summer season for Muktsar and Ferozepur districts respectively. These values are within the safe limits recommended by International Commission on Radiological Protection (ICRP).

Uranium, radium and radon exhalation studies in geological samples belonging to some areas of punjab, using track etching technique.

With a view to prospect the uranium, radium and radon concentration and related health risk assessments in areas of Muktsar and Ferozepur districts in Punjab, the fission track registration technique has been used for the analysis of water and soil samples. Uranium content in water ranged from 5.47 to 10.19 microg/l(-1) and 6.28 to 11.74 microg/l(-1) for Muktsar and Ferozepur respectively. Uranium content in soil samples of Muktsar and Ferozepur ranged from 1.14 to 1.90 mg/kg(-1) and 1.26 to 2.44 mg/kg(-1) respectively. Radium concentration in these soil samples has been found to vary from 3.97 to 15.94 bq/kg(-1) and 7.24 to 24.14 bq/kg(-1) for Muktsar and Ferozepur respectively. The radon exhalation values were calculated in terms of area (E(A)) and mass (E(M)). The values of E(M) ranged from 4.9 to 20.6 (mbqkg(-1) hr(-1)) for Muktsar and 9.4 to 31.3 (mbqkg(-1)hr(-1)) for Ferozepur and values of E(A) ranged from 173 to 728 (mbqm(-2)hr(-1)) for Muktsar and 330 to 1102 (mbqm(-2)hr(-1)) for Ferozepur district. These values in general are low and not significant from health hazard point of view. The values of uranium concentration in water samples of these areas are lower than those reported for soil and water samples of Himachal Pradesh. These values are also lower than those reported by Singh et al. for the rocks belonging to uranium and copper mines of Bihar.

Diurnal and monthly variation of indoor radon and thoron progeny concentrations at a hillside place of northern India.

The natural radioactivity levels all over the world can create health problems due to the inhalation of radioactive aerosols. Radon and thoron progeny content of indoor air have major contribution to natural radiation dose. In the present study, simultaneous indoor measurements of radon and thoron progeny concentrations have been carried out over a period of four months at a low activity hilly area of northern Punjab, India to see their diurnal and monthly variations. The method used for this purpose is based on the defined solid angle absolute beta counting of radioactive aerosols sampled on a filter. The average values of equilibrium equivalent radon and thoron concentrations were 5.20 Bq m(-3) and 0.235 Bq m(-3), respectively, over the period August to November 2003. Both, EECRn and EECTh show a negative correlation with temperature.
