Abstract There are few causes of treatable neurodevelopmental diseases described to date. Branched-chain ketoacid dehydrogenase kinase (BCKDK) deficiency branched-chain amino acid (BCAA) depletion and is linked a disorder characterized by autism, intellectual disability microcephaly. We report the largest cohort patients studied, broadening phenotypic genotypic spectrum. Moreover, this first study present newborn screening findings mid-term clinical outcome. In cross-sectional study, with...

Introduction: The COVID-19 pandemic has led to considerable changes in the health care system. Experts suggested that individuals protect themselves through social isolation during pandemic, and consequently, importance of telemedicine came be understood for patients with chronic diseases. Telemedicine started used developing countries where appropriate infrastructure was lacking earlier. present study investigates level satisfaction inherited metabolic disorders (IMDs) telemedicine....

The aim of this study was to evaluate the association between Pediatric Asthma Quality Life Questionnaire (PAQLQ) and Control Test (ACT) in patients with poor asthma control. Children 7-17 years age diagnosis persistent who are not on daily inhaler corticosteroid therapy were involved. At enrollment, sociodemographic asthmatic characteristics investigated pulmonary function test (PFT), ACT PAQLQ administered. Patients reevaluated following six week regular ACT, PFT performed.

Introduction: Metachromatic leukodystrophy (MLD) is a rare, demyelinating, autosomal recessive lysosomal storage disease caused by deficiency in the arylsulfatase A enzyme (ASA), which encoded ARSA gene. lack of ASA activity results an accumulation sulfatides myelin sheaths both central and peripheral nervous systems, leading to developmental neurocognitive progressive deterioration that can be observed all age groups. Methods: We present total 9 patients with MLD average 61 months, whose...

Abstract Introduction: Infection and sepsis continue to be the leading cause of morbidity death in burn injuries. Diagnosing burns is challenging as signs symptoms are not specific overlap with those related injury. While use procalcitonin (PCT) a biomarker recommended for diagnosing burns, evidence children scarce. In this study, we aimed investigate role PCT distinguishing pediatric burns. Methods: A prospective observational study was conducted single unit. Children hospitalized ≤30%...
