Challenges in institutional ethical review process and approval for international multicenter clinical studies in lower and middle-income countries: the case of PARITY study.

Background: One of the greatest challenges to conducting multicenter research studies in low and middle-income countries (LMICs) is the heterogeneity in regulatory processes across sites. Previous studies have reported variations in requirements with a lack of standardization in the Institutional Review Board (IRB) processes between centers, imposing barriers for approval, participation, and development of multicenter research.

Objectives: To describe the regulatory process, variability and challenges faced by pediatric researchers in LMICs during the IRB process of an international multicenter observational point prevalence study (Global PARITY).

Familial dilated cardiomyopathy in a child: a case report.

Background: Dilated cardiomyopathy (DCM) commonly leads to heart failure (HF) and represents the most common indication for cardiac transplantation in the pediatric population. Clinical manifestations of DCM are mainly the symptoms of heart failure; it is diagnosed by EKG, chest x-ray and echocardiography. For the idiopathic and familial diseases cases of DCM, there are no definite guidelines for treatment in children as they are treated for prognostic improvement.

Possible unusual presentation of opioid side effect in a child: a case report.

Atypical presentations are commonly encountered in the Pediatric intensive care unit (PICU) but having a high index of suspicion is crucial to prevent or treat severe and life-threatening conditions. This case describes the clinical presentation and course of a 14-month-old girl with congenital heart disease who was admitted to the PICU after cardiac repair and remained agitated, irritable, in hysteria and delirium despite adequate sedation. Different measures to relieve her condition were attempted but to no avail.

Mitochondrial depletion syndrome type 3: the Lebanese variant.

Mitochondrial DNA depletion syndrome type 3 is an emerging disorder linked to variants in the deoxyguanosine kinase gene, which encodes for mitochondrial maintenance. This autosomal recessive disorder is frequent in the Middle East and North Africa. Diagnosis is often delayed due to the non-specificity of clinical presentation with cerebro-hepatic deterioration.

Cardiac involvement in a child post COVID-19: a case from Lebanon.

We report on an 8-year-old boy, who presented to the emergency department at our institution with fever, generalised oedema and hypotension. Investigations revealed anaemia, thrombocytopenia in addition to elevated serum inflammatory markers, a negative COVID-19 PCR test and a positive COVID-19 IgG. His echocardiography was consistent with carditis in otherwise morphologically normal heart with depressed cardiac function, moderate-to-severe mitral valve regurgitation, moderate tricuspid regurgitation with an estimated right ventricular systolic pressure half systemic, trace aortic regurgitation, bilateral small pleural effusions, distended inferior vena cava and normal coronaries.

Establishing a High-Quality Congenital Cardiac Surgery Program in a Developing Country: Lessons Learned.

Developing countries are profoundly affected by the burden of congenital heart disease (CHD) because of limited resources, poverty, cost, and inefficient governance. The outcome of pediatric cardiac surgery in developing countries is suboptimal, and the availability of sustainable programs is minimal. This study describes the establishment of a high quality pediatric cardiac surgery program in Lebanon, a limited resource country.

A Novel Somatic Variant in HEY2 Unveils an Alternative Splicing Isoform Linked to Ventricular Septal Defect.

Congenital heart defects (CHDs) are the leading cause of death in infants under 1 year of age. Aberrations in the expression and function of cardiac transcription factors (TFs) are a major contributor to CHDs. Despite the numerous studies undertaken to functionally characterize these TFs, their exact role in different stages of cardiogenesis is still not fully elucidated.

The aim of the study is to describe the challenges faced during the establishment of the program and factors leading to its success.

Methods: The program establishment is described.

Spirituality among parents of children with cancer in a Middle Eastern country.

Purpose: Family caregivers of children with cancer face emotional, psychological, and spiritual challenges coping with their child's illness. For ensuring comprehensive multidisciplinary pediatric care, there is a need to understand and define what spirituality means for them in relation to their child's illness. The purpose of this study is to understand the meaning of spirituality for parents of cancer patients in Lebanon.

Dietary Zinc Intake and Plasma Zinc Concentrations in Children with Short Stature and Failure to Thrive.

Background: The burden of zinc deficiency on children includes an increased incidence of diarrhea, failure to thrive (FTT) and short stature. The aim of this study was to assess whether children with FTT and/or short stature have lower dietary zinc intake and plasma zinc concentrations compared to controls.

Methods: A case-control study conducted at the American University of Beirut Medical Center included 161 subjects from 1 to 10 years of age.

Device-associated infections in the pediatric intensive care unit at the American University of Beirut Medical Center.

Introduction: Device-associated healthcare-associated infections (DA-HAIs) are the principal threat to patient safety in intensive care units (ICUs).  The primary objective of this study was to identify the most common DA-HAIs in the pediatric intensive care unit (PICU) at the American University of Beirut Medical Center (AUBMC). Length of stay (LOS) and mortality, antimicrobial resistance patterns, and suitability of empiric antibiotic choices for DA-HAIs according to the local resistance patterns were also studied.

Acute acalculous cholecystitis in a Lebanese girl with primary Epstein-Barr viral infection.

Acute acalculous cholecystitis (AAC) constitutes 5-10% of all cases of cholecystitis in adults, and is even less common in children. The recent literature has described an association between primary Epstein-Barr virus (EBV) infection and AAC, however, it still remains an uncommon presentation of the infection. Most authors advise that the management of AAC in patients with primary EBV infection should be supportive, since the use of antibiotics does not seem to alter the severity or prognosis of the illness.

Dubowitz syndrome: common findings and peculiar urine odor.

Background: Dubowitz syndrome is a rare, autosomal recessive disorder characterized by intrauterine and postnatal growth retardation, severe microcephaly, psychomotor retardation, hyperactivity, eczema, and characteristic dysmorphic facial features. Although many cases have been reported, the cause of this disease is still unknown.

Case: We present here the case of a Lebanese girl with Dubowitz syndrome in whom an unpleasant urine odor was persistently reported since birth.

The lived experience of parents of children admitted to the pediatric intensive care unit in Lebanon.

Background: Family caregivers have a significant responsibility in the care of their child in the Pediatric Intensive Care Unit (PICU). Parents staying with their child in the PICU have particular needs that should be acknowledged and responded to by clinicians. Several studies have been conducted in the USA and Europe to try to understand the experience of family caregivers of children admitted to the Pediatric Intensive Care Unit.

Rupture of sinus of Valsalva aneurysm with aorto-biventricular fistulas and right-ventricular outflow tract obstruction: a unique association.

Sinus of Valsalva aneurysms are a rare entity. Rupture of such aneurysms is a major cause of aortocardiac fistulas usually occurring between the right sinus of Valsalva and right cardiac chambers. We report an exceptional case of a ruptured congenital sinus of Valsalva aneurysm with fistulas involving both the right- and left-ventricular outflow tracts and causing RVOT obstruction.

Absence of GJA1 gene mutations in four patients with anomalous left coronary artery from the pulmonary artery (ALCAPA).

Problem: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare form of congenital heart disease with no known genetic cause. It is usually diagnosed within the first year of life; it results in myocardial cell death, congestive heart failure and lethality if left untreated. Connexin 43alpha1 is a member of the gap junction family of proteins demonstrated by animal studies to have a role in coronary artery patterning during development.

Methods: This article describes the status of pediatric cardiology at the Children's Heart Center in the American University of Beirut Medical Center. It addresses the available clinical services as well as the research and educational activities that are present at a tertiary center in Lebanon, a developing country with a population of 4 million.

Inherited thrombophilia in childhood arterial stroke: data from Lebanon.

Pediatric ischemic stroke still represents a burden, and more than half of the survivors will experience cognitive or motor disabilities. The objective of this study was to investigate the role of thrombophilia in a cohort of children with arterial ischemic stroke. The records of infants and children with clinically and radiologically confirmed stroke were reviewed.

Management of hypertensive emergencies in children.

Pediatric hypertension is considered a relatively recent disease. Most hypertensive children do not require emergent care and can be managed in an outpatient setting. On the other hand, hypertensive emergencies and urgencies which can be encountered in the outpatient clinics, the inpatient wards or during an emergency visit need prompt recognition and treatment.

Intestinal polypoid arteriovenous malformation: unusual presentation in a child and review of the literature.

Aim: We report a jejuno-jejunal intussusception with a polypoid arteriovenous malformation as a lead point in a 12-year-old boy, presenting with lower abdominal pain and non-bloody non-projectile vomiting.

Methods: A computed tomography scan of the abdomen and pelvis showed proximal jejuno-jejunal intussusception in the right upper quadrant. Exploratory laparotomy revealed a 5.

A Lebanese family with autosomal recessive oculo-auriculo-vertebral (OAV) spectrum and review of the literature: is OAV a genetically heterogeneous disorder?

Oculo-auriculo-vertebral (OAV) spectrum summarizes a continuum of ocular, auricular, and vertebral anomalies. Goldenhar syndrome is a variant of this spectrum and is characterized by pre-auricular skin tags, microtia, facial asymmetry, ocular abnormalities, and vertebral anomalies of different sizes and shapes. Most cases are thought to be sporadic.
