Abstract Objective Delayed maturation of auditory brainstem pathway in neonates admitted to the neonatal intensive care unit (NICU) may lead to misdiagnosis of children with normal peripheral hearing and inappropriate use of amplification devices. The aim of this study is to determine the pattern of auditory brain stem response in neonates admitted to the NICU for proper hearing assessment in this high-risk population. Study Design This prospective study was conducted on 1,469 infants who were admitted to the NICU, of which 1,423 had one or more risk factors for permanent congenital hearing loss and were screened with automated auditory brain stem response (AABR). A total of 60 infants were referred for diagnostic ABR analysis after failure on AABR screening. The control group comprised 60 well-baby nursery neonates with no risk factors for PCHL. Results Mean values of absolute latencies of waves III and V; interpeak latencies I–III, III–V, and I–V; amplitude of waves I, and V; and I/V amplitude ratio at 90 dBnHL measured for the right and left ears at 1 and 3 months of age show significant difference in NICU neonates compared with controls (p < 0.05). All the diagnostic ABR measurements significantly improved at the age of 3 months (p < 0.001) except wave I absolute latency of both groups (p > 0.05). Significant correlations were found between ABR readings at the age of 1 and 3 months and the gestational age of the NICU neonates (p < 0.05). Conclusion Diagnostic ABR findings in NICU neonates suggested delayed maturation of the auditory brainstem pathway with a great impact of gestational age on this maturation. Auditory maturational changes were observed at 3 months of age of patient and control groups.

Type 1 Rop

PURPOSE: To study the incidence of retinopathy of prematurity (ROP) in a neonatal intensive care unit in Croatia and obtain information on risk factors associated with ROP. There have been limited studies on ROP in Croatia where the screening for ROP and its treatment is still insufficient and not introduced in many intensive care units. MATERIAL AND METHODS: This retrospective study included 247 premature infants admitted to the neonatal intensive care unit of University Hospital Split, over a 5-year period between January 2012, and December 2016. In this paper the relationship between clinical risk factors and the development of ROP was analyzed. RESULTS: The overall incidence for ROP was 23,9 % (59 infants), for Type 1 ROP was 9,3% (23 infants); for Type 2 ROP was 14,6% (36 infants). Median gestational age (GA) and birthweight (BW) were significantly lower among infants with ROP versus those without ROP (29: 23-34 vs. 31: 23-34,p<0,001 and 1,180:630-2,000 vs. 1485:590-2000, p<0,001 respectively). Multivariate analysis showed that only BW (p=0,029) and small for gestational age (SGA) (p=0,045) predicted the development of ROP. CONCLUSION: Birth weight and small for gestational age were the most significant risk factors for developing ROP. In comparison with studies from highly developed countries, infants with a much wider range of gestational age and birth weights are developing Type 1 ROP.

Neonatal Sepsis (NS) is a systemic infection caused by bacteria, fungi, or viruses during the first month of life. Although various studies have identified the factors associated with NS, it is a public health problem due to its high morbidity and mortality. The study aimed to identify the risk factors associated with neonatal sepsis in the Neonatal Intensive Care Unit (NICU) of a tertiary hospital in Mexico. A case-control study was carried out using records of neonates (with sepsis 39 and without sepsis 39) from January to December 2017. The risk factors studied were the sociodemographic and clinical characteristics of the mother and clinics of the neonate. The data were analyzed using the Chi2 test, Fisher's exact test, Student's t-test, and the Odds Ratio (OR). The risk factors associated with NS were gestational age (OR 0.77, CI 95% = 0.64-0.91, p = 0.004), newborn weight (OR 0.45, CI95% = 0.23-0.86, p = 0.017) and days of hospital stay (OR 1.06, CI95% = 1.02-1.10, p = 0.0014). The mother's sociodemographic and clinical factors were not associated with NS. Risk factors associated with NS were gestational age, newborn weight, and days of hospital stay.

Background: Retinopathy of prematurity is a vascular retinal disease that can cause blindness in premature new born babies. Several risk factors are associated with the incidence of ROP. Information and data on risk factors associated with ROP in context to Nepalese population is scarcely documented in literature.Objectives: The purpose of this study was to evaluate the risk factors of retinopathy of prematurity in premature infants admitted in the neonatal intensive care unit of Tribhuvan University Teaching Hospital.Methods: Neonates with gestational age of 36 weeks or less and birth weight of 2000 gram or less admitted to neonatal intensive care unit (NICU), during 2013 to 2015 were screened for retinopathy of prematurity. Risk factors and severity of retinopathy of prematurity were evaluated. The initial examination was carried out at 4-6 weeks after birth by indirect ophthalmoscope and retinopathy of prematurity positive and negative infants were compared subsequently. The Chisquare and independent t-tests were used for statistical analysis. A p value less than 0.05 was considered statistically signifi cant.Results: The incidence of retinopathy of prematurity was 22.6% and severe retinopathy of prematurity requiring treatment was observed in 3.2% of 93 neonates who had eye examinations. There was a signifi cant relationship between the occurrence of ROP and birth weight (p=0.000), gestational age (p=0.000), duration of oxygen therapy (p=0.009) and sepsis (p=0.002). However, insignifi cant relationship was observed between the occurrence of retinopathy of prematurity and gender, type of delivery, multiple gestation, premature rupture of foetal membrane, respiratory distress syndrome and hyperbilirubinaemia.Conclusion: The risk factors contributing to development of retinopathy of prematurity showed signifi cant relationship with immaturity, duration of oxygen supplementation and septicaemia.Journal of Kathmandu Medical CollegeVol. 5, No. 1, Issue 15, Jan.-Mar., 2016,page: 28-33

Objective Respiratory distress presented within the first few days of life is life-threatening and common problem in the neonatal period. The aim of this study is to estimate (1) the incidence of respiratory diseases in newborns and related mortality; (2) the relationship between acute neonatal respiratory disorders rates and gestational age, birth weight, and gender; and (3) the incidence of complications associated with respiratory disturbances. Study Design Only inborn patients with gestational age between 230/7 and 416/7 weeks having respiratory distress were included in the study. The data were collected from the medical records and gestational age was based on the menstrual dating. Results There were 8,474 live births between January 1, 2013 and June 30, 2013 in our hospital. A total of 1,367 newborns were hospitalized and oxygen therapy was applied in 903 of them because of respiratory distress. An acute respiratory disorder was found to be in 10.6% (903/8,474) among all live births. Mortality was 0.76% (66/8,474). The incidence of respiratory distress syndrome was 2.8% (n = 242). The occurrence of transient tachypnea of newborn was 3.1% (n = 270). Meconium aspiration syndrome, pneumonia, congenital diaphragmatic hernia, and pulmonary maladaptation and primary persistent pulmonary hypertension rates were 0.1, 0.7, 2.2, and 0%, respectively. Overall, 553 (61%) of the 903 newborns having respiratory diseases had complications. The occurrence of necrotizing enterocolitis, patent ductus arteriosus, bronchopulmonary dysplasia, intraventricular hemorrhage and air leak was 6.8, 19.8, 4.7, 24.9, and 5%, respectively. Conclusion This study offers an epidemiological perspective for respiratory disorders from a single-center level-III neonatal intensive care unit. Although number of births, premature newborns, extremely low birth weight/very low birth weight infants, and complicated pregnancies increase in years, decreasing rates of mortality and complications are very promising. As perinatal and neonatal cares are getting better in every day, we think that more promising results can be achieved over the coming years. Key Points
