Health Insurance: Drawing inspiration from chit funds to pool health risks efficiently.

The provision of government-funded public health services in India is grossly inadequate and 48.2% of "total health expenditure" for India is paid "out of pocket" [1]. When the total health expenditure in a household exceeds 10% of the annual income, it is considered catastrophic health expenditure (CHE) [2].

Evidence-based National Vaccine Policy.

India has over a century old tradition of development and production of vaccines. The Government rightly adopted self-sufficiency in vaccine production and self-reliance in vaccine technology as its policy objectives in 1986. However, in the absence of a full-fledged vaccine policy, there have been concerns related to demand and supply, manufacture vs. import, role of public and private sectors, choice of vaccines, new and combination vaccines, universal vs. selective vaccination, routine immunization vs. special drives, cost-benefit aspects, regulatory issues, logistics etc. The need for a comprehensive and evidence based vaccine policy that enables informed decisions on all these aspects from the public health point of view brought together doctors, scientists, policy analysts, lawyers and civil society representatives to formulate this policy paper for the consideration of the Government. This paper evolved out of the first ever ICMR-NISTADS national brainstorming workshop on vaccine policy held during 4-5 June, 2009 in New Delhi, and subsequent discussions over email for several weeks, before being adopted unanimously in the present form.

A simple circuit to deliver bubbling CPAP.

Nasal continuous positive airway pressure (CPAP), especially bubbling CPAP, is known to reduce the need for more invasive ventilation. We here describe a circuit that can deliver bubbling CPAP in resource poor settings. We describe how the oxygen concentration can be altered from 98% to 21% oxygen using this system. Addition of a humidifier in the circuit has the effect of reducing the oxygen concentration by 1 to 5%. The cost of putting together the system is approximately Rs 5000.

Platelet Distribution Width to Platelet Count Ratio as an Index of Severity of Illness.

OBJECTIVE: To prospectively validate association between the ratio of platelet distribution width (PDW)/platelet count (PCT) and pediatric intensive care unit (PICU) mortality. METHODS: The study was done in the pediatric intensive care unit (PICU). Platelet indices in the first sample taken after admission were used. In this case control analysis, cases were the patients who died in PICU and the survivors served as controls. Consecutive 209 eligible patients over a period of 15 mo from January 2014 through March 2015 were included. Exposure was PDW/PC above 0.07. Of them 174 survived and 35 died. RESULTS: The mean PDW for survivors was 16.77 (±0.92) and for those who died it was 17.33 (±1.03) (p 0.0015). Mean platelet count (PC) for survivors was 3,46,000 (±1,64,700) and for those who died it was 1,75,800 (±1,61,500) (p < 0.001). PDW/PC for survivors was 0.12 (±0.46) and for those who died it was 0.336 (±0.53) (p 0.0014). Using the cut-off of 0.07 for PDW/PC described by Golwala et al., 77.14% above the cut-off died, compared to 22.85% below that cut-off. The odds ratio (OR) for death was 10.6 (95% CI: 4.48 to 25.12). The area under the receiver operating curve (ROC) curve for PDW/PC ratio was 0.81. CONCLUSIONS: The ratio of PDW/PC, higher than 0.07 in the first sample after admission can be considered as an independent predictor of mortality with sensitivity and specificity of 77.1% and 77.5%, respectively. It may be a useful component for inclusion in composite scores for predicting mortality.

Nasal Continuous Positive Airway Pressure in Bronchiolitis: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the efficacy of nasal continuous positive airway pressure (nCPAP) in decreasing respiratory distress in bronchiolitis. DESIGN: Randomized controlled trial. SETTING: Tertiary-care hospital in New Delhi, India. Participants: 72 infants (age <1y) hospitalized with a clinical diagnosis of bronchiolitis were randomized to receive standard care, or nCPAP in addition to standard care, in the first hour after admission. 23 parents refused to give consent for participation. 2 infants did not tolerate nCPAP. PARTICIPANTS: 72 infants (age <1y) hospitalized with a clinical diagnosis of bronchiolitis were randomized to receive standard care, or nCPAP in addition to standard care, in the first hour after admission. 23 parents refused to give consent for participation. 2 infants did not tolerate nCPAP. INTERVENTION: The outcome was assessed after 60 minutes. If nCPAP was not tolerated or the distress increased, the infant was switched to standard care. Analysis was done on intention-to-treat basis. MAIN OUTCOME MEASURES: Change in respiratory rate, Silverman-Anderson score and a Modified Pediatric Society of New Zealand Severity Score. RESULTS: 14 out of 32 in nCPAP group and 5 out of 35 in standard care group had change in respiratory rate ≥10 (P=0.008). The mean (SD) change in respiratory rate [8.0 (5.8) vs 5.1 (4.0), P=0.02] in Silverman-Anderson score [0.78 (0.87) vs 0.39 (0.73), P=0.029] and in Modified Pediatric Society of New Zealand Severity Score [2.5 (3.01) vs. 1.08 (1.3), P=0.012] were significantly different in the nCPAP and standard care groups, respectively. CONCLUSIONS: nCPAP helped reduce respiratory distress significantly compared to standard care.

Discordant twins with the smaller baby appropriate for gestational age--unusual manifestation of superfoetation: a case report.

BACKGROUND: Documentation of superfoetation is extremely rare in humans., The younger foetus has invariably been small for gestational age (estimated from the date of the last menstrual bleed) in all the cases reported in the literature. We report a case where the younger twin was of appropriate size for gestation. CASE PRESENTATION: The first of twins was of 32 weeks gestation and the baby was of appropriate size and development for the gestational age. The second twin was of 36 weeks gestation. Gestational age was estimated with the New Ballard score, x-ray of the lower limbs, dental age on x-ray, and ophthalmic examination. CONCLUSION: Bleeding on implantation of the first foetus probably helped demarcate the two pregnancies. Dental age and the New Ballard score can be used to diagnose superfoetation in discordant twins, when detailed first trimester ultra-sound data is not available.

Outbreak of Coxsackie B4 arthritis among newborns and staff of a neonatal unit.

We investigated an outbreak of Coxsackie B4 arthritis in a neonatal unit involving 20 neonates and 12 staff members, over an eight-month period. Laboratory investigations, serology tests, indicate that the outbreak was caused by Coxsackie B4 virus. Contamination of one of the overhead water reservoirs, supplying the nursery, was responsible. After the water tanks were cleaned out, no new cases were reported over five years.

Swan-neck sign of the big toe - association with hypocalcaemia.

The sensitivity and specificity of a new clinical sign of hypocalcaemia were evaluated. The Swan-neck sign, wherein infants with symptomatic hypocalcaemia keep their big toe hyperextended at the metatarsophalangeal joint and flexed at the interphalangeal joint, was looked for in 25 infants presenting with non-febrile seizures, alongside their serum calcium levels. The study showed that the sign had a sensitivity of 63.6% and specificity of 66.6%. (Predictive values of positive and negative tests were 93.3% and 20%, respectively.) This is compared with the standard Trousseau and Chvostek signs.

Correlation of Infant Gender with Postpartum Maternal and Paternal Depression and Exclusive Breastfeeding Rates.

INTRODUCTION: Male bias in India has resulted in an altered sex ratio. It also results in maternal postpartum depression (PPD) and lower breastfeeding rates. We studied depression among fathers in this context. METHODS: Edinburgh postnatal depression scale (EPDS) questionnaire was administered to 479 parents separately. Breastfeeding on day 7 was determined. RESULTS: Depression was significantly higher in fathers of girls. Mean EPDS score was 5.86 ± 4.98 versus 2.5 ± 2.64 (p < 0.001). Concordance between parents was significant (r = 0.95, p < 0.001). Boys were more likely to be exclusively breastfed (64.46% versus 35.54%, p < 0.001). In second-order births, if the first born was a girl and second baby was again a girl, 23% were exclusively breastfed compared with 86% if it was boy after a girl (p < 0.001). Among parents who had EPDS scores ≥11, no babies were exclusively breastfed. Among the 25 babies who received no breast milk, 21 were girls and 4 were boys (p < 0.042). The multiple logistic regression analysis indicated that birth of girls (OR 0.269, 95% CI 0.076-0.953), high EPDS score in mothers (OR = 0.080, 95% CI 0.026-0.249), and high EPDS score in fathers (OR = 0.096, 95% CI 0.031-0.299) were associated with lower breastfeeding rates. CONCLUSION: Paternal depression correlates closely with maternal PPD and low exclusive breastfeeding of girls. Breastfeeding has implications for survival of girls. Efforts are needed to support the parents of girl children with PPD and such support must extend to fathers to improve survival.

Lactate: creatinine ratio in babies with thin meconium staining of amniotic fluid.

BACKGROUND: ACOG states meconium stained amniotic fluid (MSAF) as one of the historical indicators of perinatal asphyxia. Thick meconium along with other indicators is used to identify babies with severe intrapartum asphyxia. Lactate creatinine ratio (L:C ratio) of 0.64 or higher in first passed urine of babies suffering severe intrapartum asphyxia has been shown to predict Hypoxic Ischaemic Encephalopathy (HIE). Literature review shows that meconium is passed in distress and thin meconium results from mixing and dilution over time, which may be hours to days. Thin meconium may thus be used as an indicator of antepartum asphyxia. We tested L:C ratios in a group of babies born through thin and thick meconium, and for comparison, in a group of babies without meconium at birth. METHODS: 86 consecutive newborns, 36 to 42 weeks of gestation, with meconium staining of liquor, were recruited for the study. 52 voided urine within 6 hours of birth; of these 27 had thick meconium and 25 had thin meconium at birth. 42 others, who did not have meconium or any other signs of asphyxia at birth provided controls. Lactate and creatinine levels in urine were tested by standard enzymatic methods in the three groups. RESULTS: Lactate values are highest in the thin MSAF group followed by the thick MSAF and controls. Creatinine was lowest in the thin MSAF, followed by thick MSAF and controls. Normal babies had an average L:C ratio of 0.13 (+/- 0.09). L:C ratio was more among thin MSAF babies (4.3 +/- 11.94) than thick MSAF babies (0.35 +/- 0.35). Median L:C ratio was also higher in the thin MSAF group. Variation in the values of these parameters is observed to be high in the thin MSAF group as compared to other groups. L:C ratio was above the cutoff of 0.64 of Huang et al in 40% of those with thin meconium. 2 of these developed signs of HIE with convulsions (HIE Sarnat and Sarnat Stage II) during hospital stay. One had L:C Ratio of 93 and the other of 58.6. A smaller proportion (20%) of those with thick meconium had levels above the cutoff and 2 developed HIE and convulsions with L:C ratio of 1.25 and 1.1 respectively. CONCLUSION: In evolving a cutoff of L:C ratios that would be highly sensitive and specific (0.64), Huang et al studied it in a series of babies with severe intrapartum asphyxia. Our study shows that the specificity may not be as good if babies born through thin meconium are also included. L:C ratios are much higher in babies with thin meconium. It may be that meconium alone is not a good indicator of asphyxia and the risk of HIE. However, if the presence of meconium implies asphyxia then perhaps a higher cut-off than 0.64 is needed. L:C ratios should be tested in a larger sample that includes babies with thin meconium, before L:C ratios can be applied universally.

Evaluation of pulse-oximetry oxygen saturation taken through skin protective covering.

BACKGROUND: The hard edges of adult finger clip probes of the pulse oximetry oxygen saturation (POOS) monitor can cause skin damage if used for prolonged periods in a neonate. Covering the skin under the probe with Micropore surgical tape or a gauze piece might prevent such injury. The study was done to see if the protective covering would affect the accuracy of the readings. METHODS: POOS was studied in 50 full-term neonates in the first week of life. After obtaining consent from their parents the neonates had POOS readings taken directly (standard technique) and through the protective covering. Bland-Altman plots were used to compare the new method with the standard technique. A test of repeatability for each method was also performed. RESULTS: The Bland-Altman plots suggest that there is no significant loss of accuracy when readings are taken through the protective covering. The mean difference was 0.06 (SD of 1.39) and 0.04 (SD 1.3) with Micropore and gauze respectively compared to the standard method. The mean difference was 0.22 (SD 0.23) on testing repeatability with the standard method. CONCLUSION: Interposing Micropore or gauze does not significantly affect the accuracy of the POOS reading. The difference between the standard method and the new method was less than the difference seen on testing repeatability of the standard method.

Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), Platelet Count and Plateletcrit (PCT) as predictors of in-hospital paediatric mortality: a case-control Study.

BACKGROUND: Thrombocytopenia has been shown to predict mortality. We hypothesize that platelet indices may be more useful prognostic indicators. Our study subjects were children one month to 14 years old admitted to our hospital. AIM: To determine whether platelet count, plateletcrit (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) and their ratios can predict mortality in hospitalised children. METHODS: Children who died during hospital stay were the cases. Controls were age matched children admitted contemporaneously. The first blood sample after admission was used for analysis. Receiver operating characteristic (ROC) curve was used to identify the best threshold for measured variables and the ratios studied. Multiple regression analysis was done to identify independent predictors of mortality. RESULTS: Forty cases and forty controls were studied. Platelet count, PCT and the ratios of MPV/Platelet count, MPV/PCT, PDW/Platelet count, PDW/PCT and MPV × PDW/Platelet count × PCT were significantly different among children who survived compared to those who died. On multiple regression analysis the ratio of MPV/PCT, PDW/Platelet count and MPV/Platelet count were risk factors for mortality with an odds ratio of 4.31(95% CI, 1.69-10.99), 3.86 (95% CI, 1.53-9.75), 3.45 (95% CI, 1.38-8.64) respectively. In 67% of the patients who died MPV/PCT ratio was above 41.8 and PDW/Platelet count was above 3.86. In 65% of patients who died MPV/Platelet count was above 3.45. CONCLUSION: The MPV/PCT, PDW/Platelet count and MPV/Platelet count, in the first sample after admission in this case control study were predictors of mortality and could predict 65% to 67% of deaths accurately.

Refractive error at birth and its relation to gestational age.

PURPOSE: The refractive status of premature infants is not well studied. This study was done to find the norms of refractive error in newborns at different gestational ages. METHODS: One thousand two hundred three (1203) eyes were examined for refractive error by streak retinoscopy within the first week of life between June 2001 and September 2002. Tropicamide eye drops (0.8%) with phenylephrine 0.5% were used to achieve cycloplegia and mydriasis. The refractive error was measured in the vertical and horizontal meridia in both eyes and was recorded to the nearest dioptre (D). The neonates were grouped in five gestational age groups ranging from 24 weeks to 43 weeks. RESULTS: Extremely preterm babies were found to be myopic with a mean MSE (mean spherical equivalent) of -4.86 D. The MSE was found to progressively decrease (become less myopic) with increasing gestation and was +2.4 D at term. Astigmatism of more than 1 D spherical equivalent was seen in 67.8% of the eyes examined. Among newborns with > 1 D of astigmatism, the astigmatism was with-the-rule (vertical meridian having greater refractive power than horizontal) in 85% and against-the-rule in 15%. Anisometropia of more than 1 D spherical equivalent was seen in 31% babies. CONCLUSIONS: Term babies are known to be hypermetropic, and preterm babies with retinopathy of prematurity (ROP) are known to have myopia. This study provides data on the mean spherical equivalent, the degree of astigmatism, and incidence of anisometropia at different gestational ages. This is the largest study in world literature looking at refractive errors at birth against gestational age. It should help understand the norms of refractive errors in preterm babies.

Hepatitis B immunization: cost calculation in a community-based study in India.

BACKGROUND AND AIM: In India, approximately 65% of mothers deliver at home, and a community-based study evaluating the cost of vaccinating newborns with the first dose of hepatitis B vaccine within 48 hours has not been undertaken previously. This policy planning study was done to evaluate the costs of such immunization in India. METHODS: All mothers delivering in the study area (population 65,000) over a 1-year period were tested for hepatitis B surface antigen (HBsAg; ELISA), and babies of positive mothers were vaccinated starting at birth. The cost of such selective vaccination was calculated. The cost of nursing time required for universal immunization was calculated from the data on nursing time required for vaccination in the selective vaccination program. The national cost of universal immunization without testing was calculated as well as cost-benefit and cost-utility in terms of cost per quality-adjusted life-year (QALY) saved. Sensitivity testing considering economies of scale was also factored in. RESULTS: 1100 mothers delivered during the study period. 252 were primiparous. Nationwide universal vaccination would cost Rs 48,000 per QALY saved, which was double the per capita GNP of the country; discounted at 3% the cost was Rs 260,000. CONCLUSIONS: Universal immunization vaccination with hepatitis B vaccine is not cost-beneficial in India, since cost of every life-year gained with it will exceed India's per capita GNP.

The clinical risk index of babies (CRIB) score in India.

OBJECTIVE: To assess the usefulness of clinical risk index of babies (CRIB score) in predicting neonatal mortality in extremely preterm neonates, compared to birth weight and gestation. METHODS: 97 preterm neonates with gestational age less than 31 weeks or birth weight less than or equal to 1500 g were enrolled for the prospective longitudinal study. Relevant neonatal data was recorded. Blood gas analysis results and the maximum and the minimum FiO2 required by babies in first 12 hours of life were noted. Mortality was taken as death while the baby was in nursery. The prediction of mortality by birth weight, gestational age and CRIB score was done using the Logistic model, and expressed as area under the ROC curve. RESULTS: The area under the ROC curve for birth weight, gestational age and CRIB score was almost the same, the areas being 0.829, 0.819 and 0.823 respectively. Hence CRIB score did not fare better than birth weight and gestational age in predicting neonatal mortality. CONCLUSION: The CRIB score did not improve on the ability of birth weight and gestational age to predict neonatal mortality in the study.

Long QT syndrome manifesting as pulseless epilepsy.

A-10-year-old child admitted with repeated seizures due to the long QT syndrome is described. The cardiac origin of the epilepsy was suggested by the fact that during the episode of convulsions his peripheral pulses were not palpable.
