Oxygen care and treatment of retinopathy of prematurity in ocular and neurological prognosis

This retrospective cohort study aimed to investigate the effects of neonatal oxygen care and retinopathy of prematurity (ROP) treatment on ROP-related ocular and neurological prognoses. We included premature infants treated for ROP at a tertiary referral center between January 2006 and December 2019. Demographic and clinical data were collected from electronic medical records. Odds ratios (ORs) of oxygen care- and ROP treatment-related factors were calculated for ocular and neurological comorbidities 3 years after ROP treatment, after adjusting for potential confounders. ROP requiring treatment was detected in 171 eyes (88 infants). Laser treatment for ROP (OR = 4.73, 95% confidence interval [CI] 1.64–13.63) and duration of invasive ventilation (OR = 1.02, 95% CI 1.00–1.03) were associated with an increase in ocular comorbidities, along with a history of neonatal seizure (OR = 28.29, 95% CI 5.80–137.95) and chorioamnionitis (OR = 32.13, 95% CI 5.47–188.74). No oxygen care- or ROP treatment-related factors showed significant odds for neurological comorbidities. Shorter duration of invasive oxygen supply during neonatal care (less than 49 days) and anti-vascular endothelial growth factor injection as the primary treatment for ROP are less likely to cause ocular comorbidities. No association was identified between ROP treatment modalities and the risk of neurological comorbidities.

Novel urinary markers: taurine, dopamine and L-fucose levels in predicting neonatal seizures

Introduction and Aim: Neonatal seizure is an age specific neurological emergency. Their unique pathophysiological mechanism has become subject of interest for many research studies. The recurrence risk for seizures is high during neonatal period and currently used treatment strategies have limited efficacy in preventing it. From past decades although the treatment has not changed, there is a gradual progress in various mechanisms that are involved in generation of seizures and their response to anti-epileptics. With the emergence of new biochemical parameters for risk assessment in patients with seizures, there is a strong need for their comparative evaluation in order to evaluate their potential clinical application. So, this study was carried out to compare the urine levels of taurine, dopamine and fucose in assessing their role in mechanism of seizure. Materials and Methods: After obtaining ethical approval and consent from parents total 43 neonates, urine taurine, dopamine and fucose were measured in 24 cases of seizures and 19 apparently healthy normal controls. Dopamine and Taurine were measured using ELISA and L-fucose by Dische and Shettles method. Results: The median level of urine fucose was significantly higher in male neonates, taurine was significantly decreased in cases compared to that of controls. Males had higher preponderance to develop seizures. The median levels of urine dopamine were high in cases compared to controls but has not showed any significance. Conclusion: Amino acid like taurine, carbohydrate moiety like fucose and a neuromodulator like dopamine may have a mechanistic role in development of seizures in neonatal period.

Clinical profile, etiology, type and outcome of neonatal seizures: a hospital-based study

Background: Our study was undertaken to study the etiological factor, clinical profile, types and outcome of newborn with neonatal seizures (NNS).Methods: Our study was hospital based prospective study was done in Sheri Kashmir institute of medical sciences (SKIMS) Bemina from April 2013 to April 2015 in NICU, after obtaining ethical clearance from institutional ethical committee. All neonates fulfilling inclusion criteria were included in our study.Results: In our study, 80 neonates with seizures were included in our study, among them 48 were males and 32 were females. Majority of neonates (57.5%) developed seizures during first 72 hours of life due to birth asphyxia. Commonest types of neonatal seizures observed in our study were subtle observed in 46 cases, followed by tonic (21.2 %), clonic (14.9 %) and mixed (6.2%) seizures. Birth asphyxia was commonest cause (57.5%) of NNS, sepsis with meningitis (18.7%) followed by hypoglycemia (13.7%) and hypocalcemia (5%). Cases of birth asphyxia were associated with higher mortality (58.3%) as compared to cases with metabolic seizures.Conclusions: From our study we conclude that commonest cause of neonatal seizure was birth asphyxia occurring within 72 hours of birth. Sepsis and meningitis were also common infections resulting in neonatal seizure, while as hypoglycaemia and hypocalcemia were common biochemical abnormalities leading to NNS. Early identification and treatment are likely important for long-term outcomes in acute symptomatic seizure.
