Sydenham's chorea (SC), an autoimmune disorder affecting the central nervous system, is a pivotal diagnostic criterion for acute rheumatic fever. Primarily prevalent in childhood, especially in developing countries, SC manifests with involuntary movements and neuropsychiatric symptoms. Predominantly occurring between ages 5 and 15, with a female bias, SC may recur, particularly during pregnancy or estrogen use.

The adaptor protein 4 (AP-4) constitutes a conserved hetero-tetrameric complex within the family of adaptor protein (AP) complex, crucial for the signal-mediated trafficking of integral membrane proteins. Mutations affecting all subunits of the AP-4 complex have been linked to autosomal-recessive cerebral palsy and a complex hereditary spastic paraparesis (HSP) phenotype. Our report details the case of a 14-year-old boy born to consanguineous parents, presenting psychomotor delay, severe intellectual disability, microcephaly, and trigonocephaly.

Article Synopsis
  • Midbrain dopaminergic neurons (mDANs) are crucial for movement, cognition, and reward, and are linked to conditions like Parkinson's disease.
  • Researchers used a human iPSC reporter line to analyze the differentiation of mDANs and identified new transcription factors (TFs) that influence this process.
  • Key TFs such as LBX1, NHLH1, and NR2F1/2 were found to enhance mDAN differentiation, with specific roles in promoting neuronal microRNAs, regulating cholesterol biosynthesis, and controlling neuronal activity.

We describe an induced pluripotent stem cell (iPSC) line that was derived from fibroblasts obtained from a Parkinson's disease (PD) patient carrying the p.G2019S mutation in the LRRK2 gene and the p.N409S mutation in the GBA1 gene.

Background: Drowning is a serious and underestimated public health problem, with the highest morbidity and mortality reported among children. Data regarding pediatric outcomes of drowning are often inadequate, and data collection is poorly standardized among centers. This study aims to provide an overview of a drowning pediatric population in pediatric emergency department, focusing on its main characteristics and management and evaluating prognostic factors.
