Although rare in childhood, stroke may have a serious impact when it happens in this stage of life. Also, it may be the first sign of a systemic disease. We report 12 cases of patients with stroke treated in the Neuropediatrics Unit of Hospital de Clínicas de Porto Alegre (HCPA) from March 1997 to March 2000. All patients, from term infants to 12-year-old children hospitalized in the Pediatrics Unit of HCPA, had clinical suspicion of stroke, which was later confirmed by radiological studies. Patient follow up ranged from 1 to 6 years (mean = 3.4 years). Presenting symptoms were hemiparesis in 9 patients, seizures in 7, deviation of labial commissure in 3, and loss of consciousness in 1. The increase in the number of cases of childhood stroke identified and later confirmed by noninvasive methods had helped in the determination of different ethiologies of stroke: the most frequent being hematologic, cardiac and genetic diseases. However, our study included 6 newborns with stroke whose ethiology was not identified. Seven children with seizures received phenobarbital. Six term infants had neonatal seizures secondary to stroke and restricted to the first 72 hours of life.

Introduction: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disease and screening to detect pulmonary arteriovenous malformations (PAVMs) is important to prevent complications. In adults, transthoracic contrast echocardiogram (TTCE) is used to screen PAVMs. In children, a conservative screening method seems to be sufficient to rule out major PAVMs and prevent them from PAVM-related complications.

Hereditary haemorrhagic telangiectasia (HHT) is a vascular dysplasia inherited as an autosomal dominant trait and caused by loss-of-function pathogenic variants in genes encoding proteins of the BMP signalling pathway. Up to 90% of disease-causal variants are observed in ENG and ACVRL1, with SMAD4 and GDF2 less frequently responsible for HHT. In adults, the most frequent HHT manifestations relate to iron deficiency and anaemia owing to recurrent epistaxis (nosebleeds) or bleeding from gastrointestinal telangiectases.

Dysbiosis of the gastrointestinal tract is the most common cause of disease in childhood and adulthood. The formation of the intestinal microbiome begins in utero, and composition modification during life depends mainly on various genetic, nutritional, and environmental factors. The main cause of intestinal dysbiosis is improper nutrition due to a short period of breastfeeding, insufficient intake of fresh fruits and vegetables, and/or consumption of a large amount of processed food.

Background: Variants in the mitochondrial genome (mtDNA) cause a diverse collection of mitochondrial diseases and have extensive phenotypic overlap with Mendelian diseases encoded on the nuclear genome. The mtDNA is often not specifically evaluated in patients with suspected Mendelian disease, resulting in overlooked diagnostic variants.
Methods: Using dedicated pipelines to address the technical challenges posed by the mtDNA - circular genome, variant heteroplasmy, and nuclear misalignment - single nucleotide variants, small indels, and large mtDNA deletions were called from exome and genome sequencing data, in addition to RNA-sequencing when available.
