RESUMEN
BACKGROUND: Maintaining oxygenation during neonatal open repair of esophageal atresia/tracheoesophageal fistula is difficult. Inverse ratio ventilation can be used during one lung ventilation to improve the oxygenation and lung mechanics. OBJECTIVE: The aim of this study was to describe the impact of two different ventilatory strategies (inverse ratio ventilation vs. conventional ratio ventilation) during one lung ventilation in neonatal open repair of esophageal atresia/tracheoesophageal fistula on the incidence of oxygen desaturation episodes. METHODS: We enrolled 40 term neonates undergoing open right thoracotomy for esophageal atresia/tracheoesophageal fistula repair and randomly assigned into two groups based on inspiratory to expiratory ratio of mechanical ventilation parameters (2:1 in inverse ratio ventilation "IRV" and 1:2 in conventional ratio ventilation "CRV"). The incidence of desaturation episodes that required stopping the procedure and reinflation of the lung were recorded as the primary outcome while hemodynamic parameters, incidence of complications, and length of surgical procedure were recorded as the secondary outcomes. RESULTS: There was a trend toward a reduction in the incidence of severe desaturations (requiring stopping of surgery) with the use of inverse ratio ventilation (15% in IRV vs. 35% in CRV, RR [95% CI] 0.429 [0.129-1.426]). Incidence of all desaturations (including those requiring only an increase in ventilatory support or inspired oxygen saturation) was also reduced (40% in IRV vs. 75% in CRV, RR [95% CI] 0.533 [0.295-0.965]). This in turn affected the length of surgical procedure being significantly shorter in inverse ratio ventilation group (mean difference -16.3, 95% CI -31.64 to -0.958). The intraoperative fraction of inspired oxygen required to maintain adequate oxygen saturation was significantly lower in the inverse ratio ventilation group than in the conventional ratio ventilation group (mean difference -0.22, 95% CI -0.33 to -0.098), with no significant difference in hemodynamic stability or complications apart from higher blood loss in inverse ratio group. CONCLUSION: There may be a role for inverse ratio ventilation with appropriate positive end-expiratory pressure to reduce the incidence of hypoxemia during open repair of esophageal atresia/tracheoesophageal fistula in neonates, further studies are required to establish the safety and efficacy of this technique.

This study was designed to validate the Arabic version of the Autism Behavior Checklist (ABC) for the Egyptian population. A total of 500 mothers of children aged 4-14 years, of whom 150 had a diagnosis of ASD, 100 with intellectual disability, and 250 typically developing children completed the ABC. The factor analysis showed that 48 of 57 ABC items yielded a five-dimensional factor structure. The ABC-Arabic version indicated acceptable internal consistency (α = 0.85) and test - retest reliability (0.82). Also, the ABC exhibited good concurrent validity and discriminative validity. A cutoff score of 58 obtained a sensitivity of 94.7% and a specificity of 92.14% for detecting children with ASD. Our findings support the use of the ABC as a valid screening measure for ASD cases, and it may promote the use of the ABC for clinical and research purposes among Arabic-speaking communities.
RESUMEN
OBJECTIVES: By nature, the neonatal intensive care unit (NICU) environment is stressful for both infants and mothers. This study aimed to explore and quantify the severity of early life stressors in premature infants admitted to the NICU and evaluate the effect of cumulative neonatal stressors on maternal mental health. METHODS: This cross-sectional study included 100 preterm infants admitted to the NICU for at least 10 days. Daily experiences with painful/stressful procedures for 10 days were determined using the Neonatal Infant Stressor Scale. The included mothers were assessed for their psychological well-being 1 week after NICU admission using the Parental Stressor Scale: NICU and Edinburgh Postnatal Depression Scale. RESULTS: During the first 10 days of NICU admission, preterm infants experienced an average of 350.76 ± 84.43 acute procedures and an average of 44.84 ± 11.12 cumulative hours of chronic events, with the highest scores recorded on first 3 days of admission. Although intravenous flushing for patency was the most frequent acute procedure, blood gas sampling was the most painful. Forty-five percent of the mothers showed significant depressive symptoms, with the maternal role alteration reported as the most stressful experience, especially for young and new mothers (p < .001). The cumulative stressors experienced by infants were significantly associated with elevated maternal perception of psychological maladjustment (p < .001). CONCLUSION: This study confirmed that the NICU environment is stressful for both infants and mothers, with the total cumulative stressors experienced by preemies in the NICU having an negative impact on maternal mental health.

BACKGROUND AND OBJECTIVES: Day-case pediatric sedation is challenging. Dexmedetomidine is a sedative analgesic that does not induce respiratory depression. We compared dexmedetomidine to propofol when it was added to ketamine for sedation during pediatric endoscopy, regarding recovery time and hemodynamic changes. METHODS: We enrolled 120 patients (2-7 years in age) and randomly assigned them into two groups. Each patient received intravenous (IV) ketamine at a dose of 1 mg.kg-1 in addition to either propofol (1 mg.kg-1) or dexmedetomidine (0.5 µg.kg-1). The recovery time was compared. Hemodynamics, oxygen saturation, need for additional doses, postoperative complications and endoscopist satisfaction were monitored. RESULTS: There was no significant difference in hemodynamics between the groups. The Propofol-Ketamine (P-K) group showed significantly shorter recovery times than the Dexmedetomidine-Ketamine (D-K) group (21.25 and 29.75 minutes respectively, p <0.001). The P-K group showed more oxygen desaturation. Eleven and six patients experienced SpO2 <92% in groups P-K and D-K, respectively. A significant difference was noted regarding the need for additional doses; 10% of patients in the D-K group needed one extra dose, and 5% needed two extra doses, compared to 25% and 20% in the P-K group, respectively (p=0.001). The P-K group showed less post-procedure nausea and vomiting. No statistically significant difference between both groups regarding endoscopist satisfaction. CONCLUSIONS: The P-K combination was associated with a shorter recovery time in pediatric upper gastrointestinal endoscopy, while the D-K combination showed less need for additional doses.

Resumo Justificativa e objetivos A sedação ambulatorial pediátrica é um desafio. A dexmedetomidina é um analgésico sedativo que não induz à depressão respiratória. Comparamos a dexmedetomidina ao propofol quando associados à cetamina para sedação durante endoscopia pediátrica, quanto ao tempo de recuperação e às alterações hemodinâmicas. Métodos Foram recrutados 120 pacientes (2−7 anos de idade) que foram aleatoriamente alocados em dois grupos. Cada paciente recebeu cetamina IV na dose de 1 mg.kg‐1, além de propofol (1 mg.kg‐1) ou dexmedetomidina (0,5 µg.kg‐1). Comparamos o tempo de recuperação. A hemodinâmica, saturação de oxigênio, necessidade de doses adicionais, complicações pós‐operatórias e satisfação do endoscopista foram monitoradas. Resultados Não houve diferença significante entre os grupos no que diz respeito à hemodinâmica. O grupo Propofol‐Cetamina (P‐C) apresentou tempos de recuperação significantemente mais curtos do que o grupo Dexmedetomidina‐Cetamina (D‐C) (21,25 e 29,75 minutos respectivamente, p < 0,001). Observou‐se frequência maior de dessaturação de oxigênio no grupo P‐C. Onze e 6 pacientes apresentaram SpO2 < 92% nos grupos P‐C e D‐C, respectivamente. Uma diferença significante foi observada em relação à necessidade de doses adicionais; 10% dos pacientes no grupo D‐C precisaram de uma dose extra e 5% precisaram de duas doses extras, em comparação com 25% e 20% no grupo P‐C, respectivamente (p = 0,001). O grupo P‐C apresentou menos náuseas e vômitos após o procedimento. Não houve diferença estatisticamente significante entre os dois grupos em relação à satisfação do endoscopista. Conclusões A combinação P‐C foi associada a tempo mais curto de recuperação na endoscopia digestiva alta pediátrica, enquanto a combinação D‐C mostrou menor necessidade de doses adicionais.

ADHD is one of the most common neurobehavioral disorders among children and adolescents. In this prospective study, we aimed to measure circulating zinc and ferritin levels in children with ADHD, pick up the deficient ones to give zinc and iron supplements then compare before and after treatment according to their Conner's scores and Wecsler IQ test. Current study included fifty children diagnosed as having ADHD by DSMV criteria, their zinc and ferritin levels were measured by Colorimetric method and enzyme-linked immunosorbent assay (ELISA) respectively. They were divided into: group I (zinc only deficient),group II (zinc and ferritin deficient),group III (non-deficient), cases with mineral deficiency received zinc (55â¯mg/day) and/or iron (6â¯mg/kg/day) for 6 months then reassessed by parent Conner's rating scale. In group 1, there was no significant difference between the Wecsler verbal and non-verbal IQ scores and oppositional and cognitive problems in Conner's scores before and after zinc supplements, although there was significant improvement in attention, hyperactivity, emotional liability and impulsivity. In group II, there was significant improvement in verbal and total IQ but not in performance IQ, also there was significant improvement in hyperactivity, emotional liability and impulsivity with no significant difference in oppositional, cognitive problems and inattention before and after zinc/ iron supplements. In Conclusion, Zinc supplements in adjuvant to the main treatment significantly improved symptoms of ADHD children. However, a combined zinc and iron supplements was superior to zinc alone in alleviating ADHD symptoms as well as IQ improvement.

Propofol-induced neurotoxicity in developing brain is an evolving problem. Magnesium is proved to be neuro-protective when administered antenatally in case of pre-eclampsia and eclampsia. The aim of this work is to investigate the protective role of magnesium sulphate (MgSO4) against propofol-induced neurotoxicity in developing rats cerebral cortex (CC). Forty albino rats of the Sprague-Dawley strain aged 5 to 7 days were divided into four groups; Control group (Group A); MgSO4 group (Group B) receiving MgSO4 at a dose of 270 mgkg; Propofol group (Group C) receiving propofol at a dose of 20 mgkg; and Propofol+ MgSO4 group (Group D) receiving both drugs simultaneously. All drugs were given by intra-peritoneal (IP) injection. 48 hours following exposure, blood samples were collected from rats for cytochrome-c plasma assay. Also, Specimens from rats CC were processed for light microscopic examination. An immune-histo-chemical study was conducted using Glial Fibrillary Acidic Protein (GFAP) and Bcl-2-associated X protein (BAX).Propofol administration led to disruption of the cortical laminar architecture, with a significant decrease in the number of pyramidal cells. Also, GFAP and BAX immune-stained sections revealed a significant increase in the area percentage of their immune-reaction as compared to the control group, together with a significant increase in the serum level of cytochrome-c. Administration of MgSO4 with propofol could improve the histological picture of the cortex, including its laminar appearance and neuronal density. Also MgSO4 could decrease GFAP and BAX immune-reaction, with no change that could be noticed in the serum level of cytochrome-c. MgSO4 could be used as neuro-protective agent against propofol-induced cortical injury in infant rats

BACKGROUND: Antibodies to chromatin and soluble liver antigen have been associated with severe form of autoimmune hepatitis and/or poor treatment response and may provide guidance in defining subsets of patients with different disease behaviors. The major clinical limitation of these antibodies is their lower individual occurrence in patients with autoimmune hepatitis. AIM: To estimate the value of detection of these non-standard antibodies in autoimmune hepatitis as prognostic markers. METHODS: Both antibodies were tested by enzyme immunoassay in 20 patients with autoimmune hepatitis. RESULTS: Antibodies to soluble liver antigen were not detected in any of our patients. On the other hand anti chromatin antibodies were present in 50% (10/20). Antibodies to chromatin occurred more commonly in females than males (8/14 versus 2/6). Of the 14 patients who relapsed 8(57%) had antichromatin antibodies while they were present in only 2 out of 6(33.3%) non relapsers. Antichromatin antibodies were found more in patients with antinuclear (3/4) and anti smooth muscle antibodies (9/13) more than in those with liver kidney microsomal antibodies (1/4) and those seronegative (1/4) i.e. they were +ve in patients with type I (8/12(66.6%)) more than those with type II (1/4(25%)) and those seronegative (1/4(25%)). Antibodies to chromatin are associated with high levels of gamma globulin but yet with no statistical difference between seropositive and seronegative counterparts (p = 0.65). CONCLUSION: Antibodies to chromatin may be superior than those to soluble liver antigen in predicting relapse and may be useful as prognostic marker. Further studies with larger number of patients and combined testing of more than one antibody will improve the performance parameters of these antibodies and define optimal testing conditions for them before they can be incorporated into management algorithms that project prognosis.
