RESUMO
UNLABELLED: The optimum caffeine dose in preterm infants has not been well investigated. We aimed to compare the efficacy and safety of high versus low-dose caffeine citrate on apnea of prematurity (AOP) and successful extubation of preterm infants from mechanical ventilation. We compared high-dose (loading 40 mg/kg/day and maintenance of 20 mg/kg/day) versus low-dose (loading 20 mg/kg/day and maintenance of 10 mg/kg/day) caffeine citrate in preterm infants <32 weeks gestation, presented with AOP within the first 10 days of life. A total of 120 neonates (60 in each group) were enrolled. High-dose caffeine was associated with a significant reduction in extubation failure in mechanically ventilated preterm infants (p<0.05), the frequency of apnea (p<0.001), and days of documented apnea (p<0.001). High-dose caffeine was associated with significant increase in episodes of tachycardia (p<0.05) without a significant impact on physician decision to withhold caffeine. CONCLUSION: The use of higher, than current standard, dose of caffeine may decrease the chance of extubation failure in mechanically ventilated preterm infants and frequency of AOP without significant side effects. WHAT IS KNOWN: ⢠Caffeine therapy for treatment of apnea of prematurity has been well established over the past few years. The optimal loading and maintenance dose of caffeine in preterm infants is not well-studied. What is New: ⢠This double blind randomized controlled trial demonstrated that using a higher, than current standard, loading and maintenance doses of caffeine for treatment of apnea in preterm infants is well tolerated and significantly decrease the frequency of apnea.

UNLABELLED: Concerns of possible genotoxic effects of hyperbilirubinemia and phototherapy were raised from experimental and observational studies in neonates. This study aimed to assess the impact of hyperbilirubinemia and phototherapy on DNA damage and apoptosis in peripheral blood lymphocytes in healthy full-term infants. This study was conducted in the Children's Hospital, Mansoura University. Patients enrolled in this study were classified into three groups (each with 45 full-term infants): group 1 was composed of infants with hyperbilirubinemia requiring phototherapy, group 2 infants with physiological jaundice not requiring phototherapy, and group 3 infants without clinical jaundice. All enrolled infants were subjected to assessment of DNA damage and apoptosis in peripheral blood lymphocytes, using the comet assay and P53 by flow cytometry, consecutively. In group 1, measurements were done twice, before starting phototherapy and just before its discontinuation. DNA damage was not significantly different in the three groups, but it significantly increased after exposure to phototherapy compared to pre-phototherapy levels. There was no significant difference in P53 level in the three groups; however, it significantly increased after exposure to phototherapy. There were significant positive correlations between the duration of phototherapy and markers of DNA damage and apoptosis. CONCLUSIONS: Hyperbilirubinemia does not influence DNA damage and apoptosis, whereas phototherapy causes DNA damage and induces apoptosis in peripheral blood lymphocytes of full-term infants.

Chorioamnionitis contributes to neonatal and maternal morbidity and mortality. We aimed to evaluate of the impact of clinical and histological chorioamnionitis on mortality and morbidity of preterm infants. Maternal and neonatal data were collected in a retrospective cohort of preterm infants less than 30 weeks' gestation. Infants were divided into three groups: those born to mothers with clinical chorioamnionitis, histological chorioamnionitis, or no chorioamnionitis. Of 274 identified preterm infants, 33 infants were born to mothers with clinical chorioamnionitis, 95 to mothers with histological chorioamnionitis, and 146 to mothers with no chorioamnionitis. Data were available for 180 (78%) of the 230 survivors at 18 months corrected age. Infants in the study groups were similar in gestational age, birth weight, and sex distribution. Clinical and histological chorioamnionitis were not predictive of infant mortality, cerebral palsy, bronchopulmonary dysplasia, periventricular leukomalacia, or retinopathy of prematurity. Infants in the clinical chorioamnionitis group had significantly lower cognitive (88 ± 10), language (82 ± 12), and motor (89 ± 11) scores compared with infants in the histological chorioamnionitis group (101 ± 13, p < 0.01; 91 ± 13, p < 0.05; and 99 ± 13, p < 0.05, respectively) and to infants in the no chorioamnionitis group (99 ± 13, p < 0.01; 92 ± 15, p < 0.05; and 97 ± 13, p < 0.05, respectively). Clinical chorioamnionitis is associated with developmental delay in preterm infants despite adequate treatment.

Rapunzel syndrome is a rare form of gastric trichobezoar. A 4-year-old girl presented with generalised oedema and an epigastric mass. Her family was of a relatively low socio-economic background. There was microcytic hypochromic anaemia, hypoalbuminaemia and an elevated α1-antitrypsin clearance. Abdominal ultrasound and non-contrast computed tomography demonstrated a heterogeneous mass related to the stomach. Upper gastro-intestinal tract endoscopy failed to remove it. Surgical laparotomy was undertaken through a single anterior gastrotomy incision and a large mass was extracted which was a cast of the duodenum and stomach and had a tail of approximately 60 cm in length which extended to the jejunum. Low socio-economic status, child neglect and pica are risk factors for trichobezoars. Surgical laparotomy is the optimal treatment of large bezoars.

OBJECTIVES: To study the microbiological pattern of late onset neonatal sepsis cultures and to assess the diagnostic performance of serum (1,3)-ß-d-glucan level for early diagnosis of invasive fungemia in high-risk infants admitted to a neonatal intensive care unit. METHODS: A prospective multicenter clinical trial conducted on infants at high risk for invasive fungal infections, with suspected late onset sepsis, admitted to a neonatal intensive care unit at Mansoura University Children's Hospital and Mansoura General Hospital between March 2014 and February 2016. RESULTS: A total of 77 newborn infants with high risk of invasive fungal infection were classified based on blood culture into three groups: no fungemia (41 neonates with proven bacterial sepsis), suspected fungemia (25 neonates with negative blood culture), and definite fungemia group (11 neonates with culture-proven Candida). The growing organisms were Klebsiella spp. (14/54); Escherichia coli (12/54); Staphylococcus spp. (12/54; coagulase-negative Staphylococcus [9/54]; Staphylococcus aureus [3/54]); Pseudomonas aerouginosa (3/54); and Proteus spp. (2/54). Moreover, 11/54 presented Candida. Serum (1,3)-ß-d-glucan concentration was significantly lower in the no fungemia group when compared with the definite fungemia group. The best cut-off value of (1,3)-ß-d-glucan was 99pg/mL with sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 63.6%, 95.1%, 77.8%, 90.7%, and 88.5%, respectively. CONCLUSION: (1,3)-ß-d-glucan assay has a limited sensitivity with excellent specificity and negative predictive value, which allow its use as an aid in exclusion of invasive neonatal fungal infection. Accurate diagnosis and therapeutic decisions should be based on combining (1,3)-ß-d-glucan assay with other clinical, radiological, and microbiological findings.

BACKGROUND: Gram-negative bacteria are associated with significant morbidity and mortality in preterm and term newborns. Meropenem has widespread efficacy and often allows for monotherapy in this group. Prolonged infusion instead of infusion over 30 minutes has been suggested to result in higher microbiologic efficacy. OBJECTIVE: To compare the clinical and microbiologic efficacy and safety of prolonged infusions versus conventional dosing of meropenem in neonates with Gram-negative late-onset sepsis (GN-LOS). METHODS: A prospective, randomized clinical trial was conducted in neonates with GN-LOS admitted to neonatal intensive care unit (NICU), Mansoura University Children's Hospital, between August 2013 and June 2015. Patients were randomly assigned to receive either intravenous infusion of meropenem over 4 hours (infusion group) or 30 minutes (conventional group) at a dosing regimen of 20 mg/kg/dose every 8 hours and 40 mg/kg/dose every 8 hours in meningitis and Pseudomonas infection. Clinical and microbiologic success in eradication of infection were the primary outcomes. Neonatal mortality, meropenem-related (MR) duration of mechanical ventilation, MR length of NICU stay, total length of NICU stay, duration of respiratory support (RS), duration of mechanical ventilation, MR duration of inotropes and adverse effects were secondary outcomes. RESULTS: A total of 102 infants (51 in each group) were recruited. The infusion group demonstrated a significantly higher rate of clinical improvement and microbiologic eradication 7 days after starting meropenem therapy compared with the conventional group. Mortality and duration of RS were significantly less in the infusion group compared with conventional group. Acute kidney injury after meropenem treatment was significantly less in the infusion group compared with the conventional group. CONCLUSIONS: Prolonged infusion of meropenem in neonates with GN-LOS is associated with higher clinical improvement, microbiologic eradication, less neonatal mortality, shorter duration of RS and less acute kidney injury compared with the conventional strategy.

Caffeine is the most commonly used medication for treatment of apnea of prematurity. Its effect has been well established in reducing the frequency of apnea, intermittent hypoxemia, and extubation failure in mechanically ventilated preterm infants. Evidence for additional short-term benefits on reducing the incidence of bronchopulmonary dysplasia and patent ductus arteriosus has also been suggested. Controversies exist among various neonatal intensive care units in terms of drug efficacy compared to other methylxanthines, dosage regimen, time of initiation, duration of therapy, drug safety and value of therapeutic drug monitoring. In the current review, we will summarize the available evidence for the best practice in using caffeine therapy in preterm infants.
RESUMO
BACKGROUND: The role of pentoxifylline (PTX) in reducing mortality associated with neonatal sepsis is not well established. We aimed to assess the efficacy and safety of PTX as an adjunct to antibiotics on mortality and morbidity in preterm infants with late-onset sepsis (LOS). METHODS: Double blind, randomized controlled trial was conducted on 120 preterm infants with LOS. They were randomly assigned to receive either intravenous PTX 5 mg/kg/hr for 6 hours on 6 successive days or placebo. Death before hospital discharge was our primary outcome and secondary outcomes were length of hospital stay, duration of respiratory support, duration of antibiotics use, short-term morbidity of preterm infants, tumor necrosis factor-alpha concentrations, C-reactive protein concentrations, and adverse effects of PTX. RESULTS: A total of 120 infants were enrolled, 60 in each group, 78 (65%) infants had confirmed and 42 (35%) had suspected LOS. There were no significant differences between groups regarding mortality [6 (10%) in PTX vs. 10 (16.5%) in placebo, P = 0.44], short-term morbidity and combined mortality and/or short-term morbidity [18 (30%) vs. 24 (40%), P = 0.23]. PTX therapy was associated with significant reduction of serum tumor necrosis factor-alpha and C-reactive protein concentrations. The length of hospital stay, durations of respiratory support and antibiotic therapy were significantly shorter in the PTX group. Patients in PTX group had less need for vasopressors, lower incidence of metabolic acidosis, disseminated intravascular coagulopathy and thrombocytopenia. No adverse effects to PTX were reported. CONCLUSIONS: PTX has a beneficial adjuvant effect to antibiotic therapy in preterm infants with LOS without significant impact on neonatal mortality and morbidity.

RESUMO
Patent ductus arteriosus (PDA) is a common clinical condition in preterm infants. Preterm newborns with PDA are at greater risk for several morbidities, including higher rates of bronchopulmonary dysplasia (BPD), decreased perfusion of vital organs, and mortality. Therefore, cyclooxygenase (COX) inhibitors and surgical interventions for ligation of PDA are widely used. However, these interventions were reported to be associated with side effects. In the absence of clear restricted rules for application of these interventions, different strategies are adopted by neonatologists. Three different approaches have been investigated including prophylactic treatment shortly after birth irrespective of the state of PDA, presymptomatic treatment using echocardiography at variable postnatal ages to select infants for treatment prior to the duct becoming clinically significant, and symptomatic treatment once PDA becomes clinically apparent or hemodynamically significant. Future appropriately designed randomized controlled trials (RCTs) to refine selection of patients for medical and surgical treatments should be conducted. Waiting for new evidence, it seems wise to employ available clinical and echocardiographic parameters of a hemodynamically significant (HS) PDA to select patients who are candidates for medical treatment. Surgical ligation of PDA could be used as a back-up tool for those patients who failed medical treatment and continued to have hemodynamic compromise.

Resumo Objetivos: Estudar o padrão microbiológico das culturas de sepse neonatal de início tardio e avaliar o desempenho diagnóstico do nível de (1,3)-β-D-glucano no soro para diagnóstico precoce de fungemia invasiva em neonatos de alto risco internados em uma unidade de terapia intensiva neonatal. Métodos: Ensaio clínico multicêntrico prospectivo conduzido em neonatos internados em uma unidade de terapia intensiva neonatal com suspeita de sepse de início tardio que estavam em risco de infecções fúngicas invasivas no hospital universitário infantil de Almançora e no hospital geral de Almançora entre março de 2014 e fevereiro de 2016. Resultados: Foram classificados 77 neonatos recém-nascidos com risco de infecção fúngica invasiva, com base na hemocultura, em: grupo sem fungemia, incluindo 41 neonatos com sepse bacteriana comprovada, grupo com suspeita de fungemia, incluindo 25 neonatos com hemocultura negativa; e grupo com fungemia definida, incluindo 11 neonatos com Candida comprovada por cultura. Os organismos em crescimento foram: {Klebsiella spp 14/54; E. coli 12/54; Staphylococcus spp 12/54 (Staph coagulase negativa 9/54; Staph aureus 3/54); pseudomonous aerouginosa 3/54 e Proteus spp 2/54}, além de 11/54 Candida. A concentração de (1,3)-β-D-glucano no soro foi significativamente inferior no grupo sem fungemia em comparação ao grupo com fungemia definida. O melhor valor de corte da (1,3)-β-D-glucano foi 99 pg/mL com sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e precisão de 63,6%, 95,1%, 77,8%, 90,7% e 88,5%, respectivamente. Conclusão: O ensaio de (1,3)-β-D-glucano possui sensibilidade limitada com especificidade e valor preditivo negativo excelentes que possibilitam seu uso e ajudam na exclusão de infecção fúngica invasiva neonatal. O diagnóstico preciso e as decisões oterapêuticas devem ter como base a combinação di ensaio de (1,3)-β-D-glucano com outros achados clínicos, radiológicos e microbiológicos.
