Maternal Risk Factors and Morbidity Pattern of Very Low Birth Weight Infants: A NICU Based Study at Eastern Nepal.

Background: Preterm deliveries of babies weighing less than 1500 grams (VLBW, very low birth weight) are of major concern because of maximum perinatal morbidity and mortality found in this group. VLBW babies overload the neonatal intensive care unit (NICU) and their mortality contributes significantly to neonatal and infant mortality. Objectives: To study the common maternal risk factors associated with VLBW births. To study the morbidity and mortality patterns of VLBW babies. Methods: This was a hospital based retrospective study done in NICU of BP Koirala Institute of Health Sciences. Data were collected from medical records of VLBW babies admitted in NICU over a period of three years (13 April 2005 to 12 April 2008). Data were analyzed with SPSS 10.0 software. Results: Data of 140 VLBW babies were analyzed. Mean birth weight was 1188.9 (±212.78), 10.7% were home deliveries, 24.3% were twins, 31.4% required active resuscitation at birth and 46.4% were exposed to antenatal steroid. Common maternal risk factors associated with premature deliveries were inadequate antenatal check up (ANC) visits (95.7%), twin pregnancy (24.3%), antepartum hemorrhage (APH, 28.6%), premature rupture of membrane (23.6%), pregnancy induced hypertension (12.9%), bad obstetric history (12.9%) and maternal age less than 20 years (8.6%). Common morbidities among VLBW babies were clinical sepsis (77.1%), non physiological hyperbilirubinemia (73.6%), apnea (48.6%), shock (42.9%), hypoglycemia(39.3%), anemia (29.3%), hyaline membrane disease (HMD, 21.4%), patent ductus arteriosus (15.0%), severe hypothermia (12.1%), culture proven sepsis (15.7%), retinopathy of prematurity (5.7%), and bronchopulmonary dysplasia (3.6%). Overall survival was 54.3% and major causes of death were HMD (51.0%) and sepsis (34.7%). Median durations of hospital stay were 17.5 days for survivors and five days for expired cases. Conclusion: Increasing the coverage of ANC visits, early diagnosis and treatment of APH and pregnancy induced hypertension, discouraging the childbirth at too young age, early diagnosis and treatment of acute infections and chronic medical diseases in mothers are important measures to decrease the burden of VLBW births. Common morbidities in VLBW babies are sepsis, HMD, apnea, hyperbilirubinemia, patent ductus arteriosus, shock, anemia, hypoglycemia, hypothermia and hypocalcemia. Common causes death of VLBW babies are HMD and sepsis. Overall survival of VLBW babies in our settings is less. More numbers of well equipped NICUs and services like surfactant therapy are needed to improve survival of VLBW infants in our set up.

Pediatric and neonatal tetanus: a hospital based study at eastern Nepal.

A prospective hospital based study of childhood (<15 yrs) and neonatal tetanus cases from July 2004 - May 2006 was done to study the demography, clinical features and outcome of pediatric and neonatal tetanus cases at BPKIHS. During the study, 24 cases of tetanus were admitted from 9 districts including 5 neonatal tetanus. Among children with tetanus, 31.5% received 3 doses of DPT and 10.5% received TT vaccine as tetanus prophylaxis. In 16.0% children there was no recognizable injury preceding the disease. Otitis media preceded tetanus in 16.0%. All neonatal tetanus cases occurred following umbilical sepsis. Despite their mothers receiving 2 doses of TT during pregnancy, 2 neonates developed tetanus. A neonate delivered in hospital also developed neonatal tetanus. Average incubation period was 7.7 days and average onset time was 16.9 hours. Short onset time predicted the favorable outcome (p=0.005). Generalized tetanus cases were 75.0%, neonatal tetanus 21.0% and cephalic tetanus 4.0%. Generalized spasm was present in all cases. Common autonomic dysfunctions were fever, tachycardia and hypotension. Respiratory failure, aspiration pneumonia, rhabdomyolysis and seizure were common complications. Only one case received Intensive Care Unit (ICU) care. Survival rate was 21.1% for childhood tetanus and 40.0% for neonatal tetanus. Respiratory failure was the cause of death in majority. Study finds tetanus as an important disease in eastern Nepal, with substantial morbidity and mortality, primarily affecting the unvaccinated and inadequately vaccinated individuals. Despite lack of adequate resources, we can still manage tetanus cases with comparable outcome to other case series reported in the literatures.

Profile of renal diseases in Nepalese children.

AIM AND OBJECTIVES: To find out the profile of renal diseases in children hospitalized in the pediatric department of the tertiary care university teaching hospital in Eastern Nepal. MATERIALS AND METHODS: A retrospective chart review of all the patients admitted at the department of pediatric from April 2002 to March 2007 was carried out for the presence of any renal diseases on the basis of their clinical presentation, laboratory findings and final diagnosis. RESULTS: A total number of 10,396 children were admitted during the study period out of which 651 (6.3%) children had renal disease. Among them, nephrotic syndrome seen in 222 patients (34.1%) was the commonest renal disease, followed by post streptococcal nephritis in 187(28.7%) and hemolytic uremic syndrome 66(10.1%), other renal diseases seen were acute renal failure in 25 (3.9%), lupus nephritis 24 (3.7%), urinary tract infection in 23 (3.5%) Henoch-Schönlein Purpura (HSP) nephritis 26 (4%), chronic renal failure in 27 (4.2%) and other miscellaneous causes 51 (7.8%). CONCLUSION: A substantial number of children are hospitalised with renal diseases, and current trends indicate that majority of them are preventable. In near future, there is a need to develop a comprehensive service for the children with kidney diseases in Nepal.

Clinico- Biochemical Profile of Neonatal Seizure.

Objectives: The present study was undertaken to study the incidence, etiological factor, and days of onset, clinical types and biochemical abnormalities in babies having neonatal seizures. Materials and Methods: This is a retrospective, observational hospital based study. Ninety neonates, who developed seizures before 28 days of life and admitted to neonatal intensive care unit and nursery with neonatal seizure, were evaluated for incidence, etiological factor, clinical types and biochemical abnormalities found in neonatal seizure. The variables were analysed using Chi- Square and student t- test. Results: The incidence of neonatal seizure was 10.3/ 1000 live births. The seizures were common in male babies. 65 (72.2%) neonates were born to multiparous women while 35 (38%) were born to primigravidas. In birth asphyxia (n= 40), the most common type of seizure observed was subtle seizure 20 (50%), followed by focal clonic 10 (25%) and multifocal clonic 5 (12.5%). Tonic type of seizure was observed in 3 (7.5%) and myoclonic in 2 (5%). Meningitis and septicaemia was the second most common cause of neonatal seizure observed in our study. Among metabolic abnormalities hypoglycaemia was found in 20 (22%) and hypocalcaemia in 10 (11%). Conclusion: The commonest cause of seizure was birth asphyxia presenting within 72 hours of life. Among infection septicaemia and meningitis was the most common cause leading to neonatal seizure. Among biochemical abnormalities the most common cause of seizure observed in our study was hypoglycaemia and hypocalcaemia. Subtle seizures were the commonest type of seizure observed in this study.

Risk factors in early neonatal sepsis.

OBJECTIVE: To study the maternal and neonatal risk factors for neonatal sepsis. MATERIALS AND METHODS: This is prospective case control study, conducted on the neonates up to 7 days of life with a diagnosis of neonatal sepsis. There were 100 cases of neonatal sepsis and 100 control cases. The neonates in the case and control groups were evaluated for various maternal and neonatal risk factors. RESULTS: The factors which carried a significant risk for development of neonatal sepsis were premature rupture of membrane (PROM), meconium stained amniotic fluid (MSAF), foul smelling liquor, low birth weight, prematurity and low Apgar score at birth. The blood culture was positive in 22% of cases. The commonest organisms isolated were S. aureus and Klebsiella. The overall mortality was 11%. The incidence of risk factors was almost equal in culture positive and culture negative cases. CONCLUSION: The study identifies PROM, MSAF, foul smelling amniotic fluid, prematurity, low birth weight and low Apgar score at birth as strong risk factors for development of neonatal sepsis. In the presence of above factors, the neonate should be screened and observed for sepsis and considered for early institution of antibiotics.
