Low level of maternal knowledge in lactation, cesarean section and failure of early postnatal follow up was associated with the neonatal dehydration. Decreased urine and stool frequency might be considered as a warning for failure of lactation.

Persistent pulmonary hypertension of the newborn (PPHN) is a life-threatening neonatal pathology resulting from poor hemodynamic and respiratory transition to extra uterine life. Inhaled nitric oxide (iNO) is a current, commonly used treatment of PPHN. However, iNO is not available therapy in many developing countries and around 50% of infants with PPHN do not respond to iNO therapy. Sildenafil is a phosphodiesterase inhibitor type 5 (PDE5) that has been shown to selectively reduce pulmonary vascular resistance in both animal models and adult humans. Recent studies have found that in PPHN, administration of Sildenafil was associated with a significant increase in the oxygenation and a reduction in mortality with no clinically important side effects.

Prophylactic phototherapy was associated with a significant reduction of TSB in the first 48 hours of life but not later on. Clinical benefits of this strategy could not be proven.

The objective of this study was to determine the incidence, risk factors, and morbidities associated with nonoliguric hyperkalemia (NOHK) in neonates. Infants were eligible for the study if they were born at Al Qassimi Hospital and fulfilled the diagnostic criteria of NOHK (serum potassium [SK] > or = 7 mmol/L during the first 72 hours of life with urinary output > or = 1 mL/kg/h). The next admitted infant with gestational age +/- 1 week and normal SK acted as control. Exclusion criteria were severe congenital malformation, renal failure, failure of adequate urinary collection, and early blood transfusion within the first 72 hours of life. Fluid intake and urinary output were monitored. Infants who developed hyperkalemia (SK > or = 6.5 mmol/L in two nonhemolysed venous or arterial blood samples) had serum potassium measured every 4 hours until it reached below 6 mmol/L. Hyperkalemia was identified between 6 and 36 hours of age in 45 infants (peak SK 7 to 9.3 mmol/L). During the time of the study, the prevalence of NOHK was 24% among extremely-low-birth-weight infants (with birth weight < 1000 g) who comprised 83% of those identified. Of infants with NOHK, 13% developed tachycardiac arrhythmia and 17% died. NOHK was significantly associated with fetal distress, early metabolic acidosis, early hyperglycemia, and absence of antenatal steroid administration. Hyperkalemic infants had significantly lower serum calcium and higher serum phosphorous, urea, and creatinine. Early polyuric episodes and high urinary output were also more common in hyperkalemic infants. NOHK affects mainly preterm infants. Electrolyte disturbance and increased serum urea and creatinine were associated with hyperkalemia. Infants with NOHK also had high incidence of cardiac arrhythmias and mortality.

Our objective was to compare the efficacy and safety of rectal cation-exchange resin (Kayexalate) versus salbutamol infusion for the treatment of nonoliguric hyperkalemia (NOHK) in preterm infants. Data of all neonates born with NOHK during the study period of 6 years and 8 months were recorded. Diagnostic criteria of NOHK included serum potassium (SK) concentration > or = 7 mmol/L during the first 72 hours of life with urine output > or = 1 mL/kg/hour. This before-after study was divided according to the date of admission; the first 15 patients were treated with Kayexalate enema 1 g/kg every 4 hours, and the remaining 30 patients were treated with intravenous salbutamol infusion as 4 mug/kg every 4 hours. Treatment discontinued when SK became < 6 mmol/L. SK was measured every 4 hours. Daily urine was collected. Fluid intake and output, serum electrolytes, urea, creatinine, and glucose concentrations were obtained in all infants every 12 hours. All infants were observed with a cardiorespiratory monitor and oxygen saturation and blood pressure measurements. Perinatal characteristics in both groups were comparable. Mean gestational age was 26 and 28 weeks for salbutamol and Kayexalate, respectively. The peak of SK ranged between 7 and 9.3 mmol/L in the Kayexalate group and between 7 and 8.7 mmol/L in the salbutamol group ( P = 0.64). At 12 hours of treatment, SK became normal in only 4 patients (26%) in the Kayexalate group compared with 18 patients (60%) in the salbutamol group ( P = 0.003). The number of doses of Kayexalate administration was significantly higher than the doses of salbutamol ( P = 0.003). No significant side effects were detected in the salbutamol-treated infants. In contrast, there were two cases of severe ventricular tachycardia and one case of intestinal obstruction in the cation-exchange resin group. We concluded that salbutamol infusion is more effective with faster action and safer than cation-exchange resin (Kayexalate) for the treatment of NOHK in preterm infants.

A previous study found that early intravenous indomethacin administration prolonged respiratory support in very low birth weight infants. We have, therefore, designed a randomized, double blind controlled study to evaluate the oxygenation, and surfactant requirements in preterm low birth weight infants receiving early indomethacin administration. Premature neonates who received surfactant therapy and on mechanical ventilation were prospectively randomized to receive either placebo or indomethacin (0.2 mg/kg intravenously at 12 postnatal hours and every 24 h for two more doses). Oxygenation was assessed by FiO2 required and arterial/alveolar oxygen (a/A O2) ratio during the first 48 h of life. The doses of surfactant were compared between the two groups. Twenty-seven infants (n = 14 of early indomethacin and n = 13 of placebo group) fulfilled inclusion criteria. At admission to the study, there were no differences in the birth weight, gestational age, sex, Apgar scores, a/A O2 ratio, and FiO2. The control group exhibited a significant improvement in oxygenation (FiO2 requirement and a/A O2 compared with the early indomethacin group at 24 (P = 0.026 and 0.02, respectively) and 48 h of life (P = 0.037 and 0.026, respectively). The requirement of surfactant was significantly larger in the early indomethacin group (P = 0.029). Early indomethacin administration increases oxygen and surfactant requirement.

The successful implementation of pediatric audiology services depends on parental engagement and support. It is essential to analyze the gaps in knowledge level and attitude of the parents in United Arab Emirates (UAE), towards pediatric hearing loss and pediatric audiology services. The present study aimed to assess the knowledge and attitude of parents in Sharjah, UAE.A cross-sectional survey was administered to 295 parents in a tertiary care hospital setting. The self-reported questionnaire consisted of 26 items. 34.2% of the parents ascertaining good knowledge and 65.8% reported poor knowledge regarding the various factors related to the childhood hearing loss. Further, 86.2% of parents reported positive attitudes regarding accessing pediatric audiology services. A significant association was found between age groups, educational status, and knowledge levels. The study highlights the poor knowledge demonstrated by parents in the UAE regarding hearing loss and its associated risk factors. Findings outline the critical need in the region to enhance parental awareness. More health promotion activities and community outreach campaigns are necessary to increase the uptake of pediatric audiology services in the region.
