Background And Aim: Megaloblastic anemia (MA) is a rare pathology in childhood due, in the majority of cases, to a deficiency of folic acid and/or vitamin B12 (cobalamin). This study aims to determine the epidemiological, clinical, and paraclinical profiles of MA in children and to specify its etiologies, therapeutic modalities, and treatment responses.
Methods: This is a retrospective descriptive study of MA cases in children carried out in the General Pediatrics Department of the Hedi Chaker University Hospital of Sfax over a period of 42 years, from January 1979 to December 2021.

Dias-Logan syndrome, also known as intellectual developmental disorder with persistence of fetal hemoglobin (HbF), or -related intellectual developmental disorder, is an extremely rare neurogenetic disorder characterized by intellectual disability (ID), delayed psychomotor development, variable dysmorphic features, and asymptomatic persistence of fetal hemoglobin. The prevalence and incidence of this condition are currently unknown. We report an 8-year-old Han Chinese male patient with Dias-Logan syndrome who carries a heterozygous pathogenic variant, c.

Objective: Mutations in the thyroid hormone (TH) transporter monocarboxylate transporter 8 (MCT8) cause Allan-Herndon-Dudley syndrome (AHDS), a severe form of psychomotor retardation with muscle hypoplasia and spastic paraplegia as key symptoms. These abnormalities have been attributed to an impaired TH transport across brain barriers and into neural cells thereby affecting brain development and function. Likewise, Mct8/Oatp1c1 (organic anion transporting polypeptide 1c1) double knockout (M/Odko) mice, a well-established murine AHDS model, display a strongly reduced TH passage into the brain as well as locomotor abnormalities.

Introduction: Nemaline myopathy (NM), also known as Nemalinosis, is a rare congenital muscle disease with an incidence of 1 in 50000. It is characterized by nemaline rods in muscle fibers, leading to muscle weakness. We reported a case of NM revealed by cardiac involvement, and we highlighted the challenges in diagnosing this condition as well as its poor prognosis.
