Zinc Supplementation in Preterm Neonates and Neurological Development: A Randomized Controlled Trial.

Objective: To assess the effect of zinc supplementation on neuro-development and growth of preterm neonates. Setting: Referral neonatal unit of a teaching hospital. Design: Open-labeled Randomized controlled trial. Participants: 100 preterm neonates. Intervention: Participants randomized to receive oral zinc (study group) or not (controls). Main Outcome Measures: Primary: Neuro-development status at 40 weeks post conceptional age and at 3 month corrected age using Amiel-Tison neurologic assessment. Secondary: anthropometry and serum alkaline phosphatase at 3 months corrected age. Results: At 40 weeks post-conceptional age, greater number of zinc supplemented infants demonstrated alertness and attention pattern normal for their age (P=0.02). Higher number of controls showed signs of hyper-excitability at 40 week post-conceptional age (P=0.001) and 3 months corrected age (P=0.003). At 3 month corrected age, mean serum alkaline phosphatase level was significantly higher in the study group compared to controls. Conclusion: Zinc supplementation till 3 month corrected age in preterm breastfed infants improves alertness and attention pattern; and decreases signs of hyperexcitability, and proportion with abnormal reflexes.

Pulse Oximetry Screening to Detect Cyanotic Congenital Heart Disease in Sick Neonates in a Neonatal Intensive Care Unit.

Objective: To evaluate pulse oximetry for detection of congenital cyanotic heart disease in sick neonates using echocardiography as gold standard. Methods: Pulse oximetry readings were taken at admission from 950 neonates from right upper limb and either foot with infant breathing room air. Pulse oximetry was considered abnormal if oxygen saturation at room air measured <90% or difference between right hand and foot was more than 3%. Persistent abnormality was considered positive result. Echocardiography was performed on all neonates with positive pulse oximetry (study group) and on one subsequent neonate with negative screen for each neonate with positive screen (controls). Results: Pulse oximetry was positive in 210 neonates. It detected 20 out of 21 (95.2%) true positives. The sensitivity, specificity, positive predictive value, negative predictive value and odds ratio (95% CI) of pulse oximetry was 95.2%, 52.4 %, 9.5, 99.5 and 22 (5.3, 91.4), respectively. Conclusion: Pulse oximetry screening is useful in detecting cyanotic heart diseases in sick newborns.

Neonatal Zygomycosis with Gastric Perforation.

Zygomycosis is a rare infection in neonates. The clinical presentation is non-specific and diagnosis most often is made at autopsy. Surgical debridement performed early improves survival. We report a case of neonatal zygomycosis with gastric perforation.

Vitamin E Supplementation in Exclusively Breastfed VLBW Infants.

We conducted this study to evaluate the adequacy of breastmilk as a source of vitamin E in exclusively breastfed VLBW infants. Such infants (n=44) were randomly allotted to receive vitamin E supplementation (n = 23); the rest (n = 21) did not receive vitamin E. After 21 days, the vitamin E level in the supplemented group was 0.78 + 0.26 mg/dL as compared to 0.77+ 0.25 mg/dL in the unsupplemented group (P=0.69). The ratio of Vitamin E to lipids was also comparable in the two groups, (P=0.65). We concluded that vitamin E supplementation is not routinely needed in VLBW infants.

Cogenital Intrapericardial Herniation of Liver.

Intrapericardial herniation of liver is a rare form of diaphragmatic hernia. We report a 30-hour old baby with right congenital anterior diaphragmatic hernia masquerading as congenital pneumonia with cardiomegaly. It is prudent to consider congenial anterior diaphragmatic hernia in any newborn with unexplained respiratory distress, cardiomegaly and pericardial effusion.

Positron Emission Tomography in Congenital Hyperinsulinism.

We report a case of congenital hyperinsulinism with diffuse pancreatic abnormality diagnosed preoperatively by using [18-F]-L-DOPA positron emission tomography (PET). The infant was referred to us for recurrent hypoglycemia. Critical blood sample revealed increased insulin: glucose ratio. DOPA PET scan revealed diffuse involvement of pancreas. Subtotal (95%) pancreatectomy was done. Infant remained euglycemic on breast feeds at discharge.

Systemic Inflammatory Response Syndrome in Home Delivered Neonates: A Prospective Observational Study.

Objective To determine the severity of systemic inflammatory response syndrome (SIRS) at admission, bacteriological profile, antibiotic sensitivity of pathogens and factors associated with fatality in home delivered neonates with sepsis. Methods This was a prospective observational study conducted in the referral neonatal unit of a teaching hospital admitting extramural neonates. The subjects comprised of 80 home delivered neonates presenting with systemic inflammatory response syndrome at admission. Skin temperature, oxygen saturation, capillary refill time and blood sugar were recorded in all the neonates at admission. For Blood culture, blood collected by venipuncture was placed in a tryptic soy broth culture bottle. Serum TNF-α was measured by ELISA kit. Results Early onset sepsis was seen in 27.5%. The commonest clinical feature in the study population was decreased oral acceptance (53.8%). The mean distance traveled to reach the hospital was 19±3 km. At admission, acute physiological derangement in the form of abnormal skin temperature, oxygen saturation, perfusion and blood sugar was present in 53 neonates and 44% had more than one parameter deranged. Only 11% cases had early sepsis while the SIRS was well established in the rest. Klebsiella pneumoniae was the predominant bacteria isolated in 14 cases. Resistance of Klebsiella isolates to Ampicillin was 90% and to Gentamicin 57%. The fatality was higher in presence of advanced stages of SIRS at admission. Conclusion SIRS was well established in 89% cases at admission. Klebsiella resistant to antibiotics was the predominant etiological organism. Fatality was higher in culture positive sepsis and in those associated with meningitis and pneumonia.

Chlamydia trachomatis causing neonatal conjunctivitis in a tertiary care center.

Chlamydia trachomatis is considered a major aetiological agent of conjunctivitis in newborns. The objective of the present study was to determine the aetiology of neonatal conjunctivitis and clinico-epidemiological correlates of chlamydial ophthalmia neonatorum. Fifty-eight newborns with signs and symptoms of conjunctivitis were studied. Conjunctival specimens were subjected to Gram staining, routine bacteriological culture, culture for Neisseria gonorrhoeae and direct fluorescent antibody (DFA) staining for diagnosis of C. trachomatis infection. C. trachomatis was detected in 18 (31%) neonates. Findings suggest that since C. trachomatis is the most common cause of neonatal conjunctivitis, routine screening and treatment of genital C. trachomatis infection in pregnant women and early diagnosis and treatment of neonatal Chlamydial conjunctivitis may be considered for its prevention and control.

Perceived breast milk insufficiency in mothers of neonates hospitalized in neonatal intensive care unit.

Objective. a) To study the frequency of perceived breast milk insufficiency in mothers of hospitalized neonates. b) To assess subsequent duration of exclusive breast feeding and growth (upto three months) in neonates whose mothers perceived breast milk insufficiency. Methods. Neonates whose mothers were willing to breastfeed their babies were included in the study. Their breastfeeding status was assessed and the mother’s perception of breastfeeding was elicited as per WHO guidelines. In mothers who perceived breast milk insufficiency (crisis group),causes for such a perception were looked into. Mothers were regularly counseled to breastfeed the infant After discharge the mother infant dyad were followed up for three months and babies evaluated for weight, length and head circumference. Results. Three hundred and seven neonates and their mothers fulfilling the inclusion criteria were enrolled in the study. Perceived breast milk insufficiency was present in 208 (68%) mothers. Common reasons for such a perception were irrational. In the crisis group, 35% mothers had preterm babies as compared to 16% in the non crisis group (p =0.001). One hundred and fifty three mothers (73.33%) in the crisis group had breast milk sodium levels>16 mmol/L as compared to 12 mothers (12.12%) in the non crisis group (p 0.001). Micturition <6 times/24 hours was reported in 166 (83%) mothers in crisis group as compared to 18 (18.1%) mothers in non crisis group. All mothers who perceived breast milk insufficiency could be helped by lactation management and exclusively breastfed their babies. All infants were exclusively breastfed at discharge and at three month follow up. The growth of the infants was satisfactory in the crisis group at 3 months follow up. Conclusion. The Present study suggests that lactation failure following delayed initiation of breastfeeding can be countered by subsequent intensive counselling. Emphasis is required on counselling for breastfeeding in primary neonatal care.

Prevalence of celiac disease in north indian children.

Celiac disease (CD) is being increasingly reported from the wheat-eating population of north India. However, the exact prevalence of CD in children is not known as population screening studies are scarce. Our study aimed to determine the prevalence of CD in 400 children, 6 months to 12 years of age attending pediatrics department of a tertiary care hospital in north India. The study population was screened for anti-tissue transglutaminase (tTG) antibodies. Endoscopic duodenal biopsy was done in the anti–tTG positive subjects. Four patients were diagnosed with CD as per the modified ESPGHAN criteria. The prevalence of CD thus was 1%, which was in concordance with screening studies using serological markers conducted in the West.

Newborn care practices in an urban slum of Delhi.

BACKGROUND: Despite efforts by government and other agencies, neonatal morbidity and mortality continues to be high in India. Among other reasons, newborn care practices are major contributors for such high rates. AIMS: To find out the newborn care practices including delivery practices, immediate care given after birth and breast-feeding practices in an urban slum of Delhi. SETTINGS AND DESIGN: Community based, cross-sectional survey in a resettlement colony (a type of urban slum). MATERIALS AND METHODS: Semi-structured, pre-tested schedule was used to interview 82 mothers of newborns in the study area. STATISTICAL ANALYSIS: Data was analyzed using Epi - info version 6.04. Fischer exact test and chi2 test were applied. A P value of less than 0.05 was considered significant. RESULTS AND CONCLUSION: More than half i.e. 26 (56.1%) of home deliveries, which were mostly conducted by dais (24, 91.3%) or relatives in 4 (8.7%) of home deliveries. Bathing the baby immediately after birth was commonly practiced in 38 (82.6%) of home deliveries. Finger was used to clean the air passage in most of the home deliveries (29, 63%). About 61% (28) of home delivered newborns were not weighed at birth. Rooming in was practiced in majority of the cases. A few of home delivered neonates (12) were given injection tetanus toxoid by unqualified practitioners. Use of clip, band or sterile thread to tie the cord and no application to the cord was significantly higher in institutional deliveries. Breast milk as the first feed was significantly more in institutional deliveries. There is an urgent need to reorient health care providers and to educate mothers on clean delivery practices and early neonatal care.

Acute renal failure in neonatal sepsis.

OBJECTIVE: To evaluate the occurrence of acute renal failure (ARF) and the factors associated with it in cases of neonatal sepsis. METHODS: The case control study was conducted in the referral neonatal intensive care unit of a tertiary teaching hospital. 200 out born neonates with sepsis admitted to the nursery from January to July 2003 were evaluated for presence of ARF (cases) or not (controls). Sepsis was diagnosed on the basis of either a positive sepsis screen (immature: total (I:T) neutrophil ratio > 0.2, micro-ESR > age in days + 2 mm or> 15 mm, CRP> 6 mg/dl, TLC< 5000 cells/mm3; 2 or more positive) or a positive blood culture in symptomatic neonates. ARF was defined as blood urea nitrogen (BUN)> 20mg/dl on two separate occasions at least 24 hours apart. Oliguria was defined as urine output < 1 ml/Kg/hr. RESULTS: 52 out of 200 (26%) neonates with sepsis had ARF; only 15% of ARF was oliguric. The mean gestation of neonates with ARF was similar to those without ARF (36.1+/-4.1 wks vs. 36.6+/-3.5 wk; p = 0.41). A significantly higher number of babies with ARF weighed less than 2500 gm as compared to those without ARF (86.5% vs 67.6%; p = 0.008). The association of meningitis, disseminated intravascular coagulation (DIC) and shock was also significantly higher in neonates with ARF (46.8% vs 26.2%, p = 0.01; 65.4% vs 20.3%, p < 0.001; 71.2% vs 27.0%, p < 0.001 respectively). Mortality in neonates who developed ARF was significantly higher (70.2% vs 25%, p < 0.001). Factors including gestational age, weight, onset of sepsis, culture positivity, associated meningitis, asphyxia, shock, prior administration of nephrotoxic drugs were subjected to univariate analysis for prediction of fatality in neonates with sepsis and ARF; only shock was found to be a significant predictor of fatality (p< 0.001). ARF had recovered in 22 out of 49 neonates in whom data was available; three patients had left against medical advice. The mean duration of recovery in these 22 neonates was 5.5 days (range 1-14 days). Presence of co-existing morbidities (perinatal asphyxia/congestive heart failure (CHF)/ necrotising enterocolitis (NEC)) or nephrotoxic drugs did not alter the frequency of recovery of ARF in septic neonates (45.5% vs 44.4%,p = 0.944; 41% vs 52%, p = 0.308 respectively). CONCLUSION: Renal failure occurred in 26% neonates with sepsis. Although ARF in neonates has been reported to be predominantly oliguric, it was observed that ARF secondary to neonatal sepsis was predominantly non oliguric. Low birth weight was an important risk factor for the development of ARF. The mortality being three times higher in neonates with ARF demands a greater awareness of this entity among practitioners and better management of this condition.

Estimation of rewarming time in transported extramural hypothermic neonates.

OBJECTIVES: To evaluate the time taken for rewarming hypothermic neonates and to correlate the time taken for rewarming with severity of hypothermia (WHO classification), weight, gestational age and associated morbidity. METHODS: 100 extramural neonates transported to the Referral neonatal unit of a teaching hospital, with weight more than 1000 grams and abdominal skin temperature less than 36.5 oC at admission were included in the study. Hypothermia was classified as per WHO recommendations. Clinical features including age, weight, gestational age, clinical diagnosis and vitals were recorded at the time of admission. Rewarming was done under a servo-controlled radiant warmer, in skin mode at set temperature of 37 oC. Skin and air temperatures measured by the thermistor probe were recorded at the time of admission and then at least every 15 minutes till skin temperature reached 36.5 oC. The neonates were monitored for oxygen saturation, blood glucose and capillary filling time and stabilized promptly. RESULTS: The mean abdominal skin temperature was 34.9 +/- 1.4 oC. 72% of babies were moderately or severely hypothermic as per WHO classification. The duration of rewarming was 4.9 +/- 0.8 min, 17.5 +/- 9.5 min and 42+/-7.9 min for mild, moderate and severe hypothermia respectively (p=0.021). The difference in rate of rewarming between various grades of hypothermia was also significant. The duration of rewarming a baby did not differ significantly between the different weight and gestational age groups. When the rate of rewarming was expressed as rise in oC per Kg body weight per hour, it was higher in smaller and more premature babies. The rate of rewarming was slower in asphyxiated babies. CONCLUSIONS: The duration of rewarming depends on the severity of hypothermia. When rewarmed under radiant warmer using servo mode, the duration of rewarming a baby is the same irrespective of weight and gestational age. Asphyxiated babies take longer time to rewarm.

Predictors of fatality in neonates requiring mechanical ventilation.

OBJECTIVE: To evaluate initial arterial blood gas, pulmonary pressures, pulmonary mechanics (compliance and resistance), pulmonary volumes, oxygenation indices and serum carotenoid levels as predictors of fatality in mechanically ventilated neonates. DESIGN: Cross Sectional. SETTING: Referral neonatal unit of a teaching hospital. SUBJECTS: 83 mechanically ventilated outborn neonates. METHODS: 83 neonates consecutively put on mechanical ventilator from March to December 2001 were enrolled in the study. The mechanical ventilator used was pressure limited time cycled ventilator with facility for online measurement of volumes and pulmonary mechanics. Arterial blood gas after half an hour of initiation of mechanical ventilation and initial pulmonary pressures, pulmonary compliance, resistance and duration of mechanical ventilation were recorded in a pre structured proforma. Initial serum carotenoid levels were also measured using spectrophotometric method. The neonates were regularly followed up for outcome. Multiple logistic regression analysis was done to find out the predictors of fatality for those variables that were significantly associated with outcome on univariate analysis. RESULTS: On univariate analysis weight ( < 2000 g), gestational age <34 weeks, pH <7.3, duration of mechanical ventilation <72 hours, a/A <0.25, compliance <1 mL/cmH2O, fraction of inspired oxygen (FiO2) >60%, oxygenation index >10, AaDO2 >250 and serum carotenoid levels < 100 microg/dL were significantly associated with fatality in neonates requiring mechanical ventilation. However, on multiple regression analysis only FiO2, gestational age and serum carotenoids < 100 microg/dL were found to be independent predictors of fatality. CONCLUSIONS: Initial FiO2 > 60%, gestational age <34 weeks and initial serum carotenoid levels < 100 microg/dL were independent predictors of fatality in neonatal mechanical ventilation. Even in a setting with high fatality rates, high risk of mortality in mechanically ventilated neonates can be identified.

Infant feeding - an evaluation of text and taught.

OBJECTIVE: Study was conducted to 1) assess knowledge of doctors, medical interns and nurses/ANMs regarding exclusive breast-feeding, management of common problems related to breast feeding and appropriate complementary foods 2) review the above aspects in books commonly read by medical and nursing students. METHODS: Cross-sectional study conducted in the department of Community Medicine, Maulana Azad Medical College, New Delhi during a seven-month period on 93 interns, 58 medical officers and 44 nurses/ Auxillary Nurse Midwives (ANMs) with the help of a pre-tested structured multiple choice questionnaire and review of some commonly read books of Pediatrics, Community Medicine and Nursing. RESULTS: The concept of 'exclusive breast-feeding' was clear to most health personnel but the fact that water should also not be given was not clear in the books reviewed. The books also lacked emphasis on management of common lactation problems and this was also seen in the knowledge of the health personnel. CONCLUSION: As inappropriate feeding practices are widely prevalent, knowledge of large proportion of health personnel is incorrect and commonly read books are inadequate on this issue, there is need for greater emphasis on this in books and training sessions.

Effect of stepwise reduction in minute ventilation on PaCO2 in ventilated newborns.

OBJECTIVE: To study the effect of step reduction of expired minute ventilation (MV) on PaCO2 in ventilated newborns and to determine whether MV within a defined range can predict PaCO2. DESIGN: Prospective descriptive. SETTING: Referral neonatal unit of a teaching hospital. METHODS: Forty neonates stable on mechanical ventilation receiving minute ventilation in the range of 150-210 ml/kg/min. were studied. The spectrum of disorders for which the babies were ventilated included apnea of prematurity in 16, pneumonia in 14, meconium aspiration syndrome in 6 and hyaline membrane disease in 4. Median age at study was 6 days and median weight at study was 2.1 kgs. The MV was reduced from 210 to 150 mL/kg/min in three steps and concomitant PaCO2 was measured. Reductions were not done if PaCO2 was more than 50 mmHg. MVs were plotted against PaCO2 and a regression equation to predict PaCO2 from MV was calculated. RESULTS: A stepwise increase was seen in CO2 with reduction of MV over the range studied. The median MV and median PaCO2 achieved in the three steps were 201 mL/kg/min and 36.7 mm of Hg, 180 mL/kg/min and 41.7 mm of Hg, 160 mL/kg/min, and 44.3 mm of Hg. The regression equation to predict PaCO2 was PaCO2 = 70 - 0.17 x MV in mL/kg/min, r = -0.45, r2 = 0.20, residual variance (s2) = 39.37; gave a predicted PaCO2 within 12.5 mmHg. for a given MV. CONCLUSION: Reducing minute ventilation led to an increase in the levels of PaCO2. Minute volumes of 160 ml/kg/min correlated with PaCO2 value of 44.3 mm of Hg. MV as low as 160 mL/kg/min are well tolerated by newborns.

Portal vein thrombosis complicating neonatal hepatic abscess.

Hepatic abscess in a neonate is a rare but serious disorder. Diagnosis of hepatic abscess requires a high index of suspicion in any septic neonate. CT scan and ultrasound of liver are the most sensitive diagnostic tests in detection of hepatic abscess. Portal vein thrombosis and portal cavernoma formation is hitherto unreported complication of neonatal hepatic abscess in English literature. Present case report highlights the difficulty in diagnosis of neonatal hepatic abscess and describes the development of portal vein thrombosis and cavernoma during its treatment.
