Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare disorder characterized by thrombocytopenia and absence or decline in the number of megakaryocytic precursors in the bone marrow. It is caused by mutations in the thrombopoietin receptor gene, c-mpl, involved in the proliferation and differentiation of megakaryocytes and platelets. The association between CAMT and central nervous system (CNS) anomalies has been reported in the literature, albeit not very frequently. Here we present a unique case where CAMT appeared associated to cerebellum agenesis, hypoplasia of the corpus callosum and brainstem, facial malformations, and developmental delay.

Epilepsy Center, Neurological Institute, Cleveland Clinic, Cleveland, Ohio, USA.
Generalized epilepsy is classically thought of as a disease of the young and adolescent, with rarely reported cases among older adults. We aimed to analyze management and outcomes in a population sparsely described in the literature through a retrospective single-center cohort design. After excluding individuals without follow-up, we identified 151 people ≥50 years at the time of electrographically confirmed generalized epilepsy.

Here, we discuss a rare and to our knowledge, the first case of an atypical Van der Knaap's disease in a 6-year-old boy who presented with motor difficulties, developmental delay, cognitive impairment, seizures. The objective of this report is to highlight its unusual findings on MRI including internal capsule, brainstem, cerebellum involvement; subependymal nodular heterotopia, subependymal cysts, cortical laminar necrosis along with typical findings of megalencephalic leukoencephalopathy and subcortical cysts. The study also underscores the clinical implications of this complex pathology, with emphasis on comprehensive neuroradiological evaluation for atypical presentations to guide better diagnostic and management outcomes.

Alcohol Clin Exp Res (Hoboken)
December 2024
Department of Psychology, Center for Behavioral Teratology, San Diego State University, San Diego, California, USA.
Background: Fine motor skill deficits have been reported for children with histories of prenatal alcohol exposure, but little is known whether impaired motor skill extends to the regulation of precision grip control.
Methods: Children with (n = 15) and without (n = 17) histories of heavy prenatal alcohol exposure used their dominant hand to grasp, lift, and hold in space a small-instrumented object with a mass of 19 g. Object mass was also experimentally increased by separately adding two aluminum cubes with mass of 200 and 400 g.
Association between chest-to-head circumference ratio at birth and childhood neurodevelopment: the Japan Environment and Children's Study.

Children born growth-restricted are well recognized to be at an increased risk of poor neurodevelopmental outcomes. This prospective study examined the influence of chest-to-head circumference ratio at birth on neurodevelopment in the first three years among children enrolled in the Japan Environment and Children's Study. We analyzed information of 84,311 children (43,217 boys, 41,094 girls).
