Functional Syncope in Children and Adolescents: A Retrospective Cohort Study.

Background: Functional syncope, or psychogenic pseudosyncope, is often under-recognized. We aimed to show that functional syncope may be diagnosed in most pediatric patients by the initial neurological consultation.

Methods: We reviewed the medical records of patients who were evaluated from 2006 to 2022 in clinic for apparent transient loss of consciousness (a-TLOC) and probable functional syncope.

Neurocognitive Profiles in Adolescents With Postural Tachycardia Syndrome and Perceived Brain Fog: A Preliminary Report.

Background: Postural tachycardia syndrome (POTS) is associated with complaints of cognitive and emotional difficulties that may contribute to severe functional disability. For high-achieving adolescents, these symptoms can result in decreased participation in school and extracurricular activities. There are very limited data comparing subjective symptom reports to neurocognitive profiles in adolescents presenting with POTS, "brain fog," and cognitive difficulties.

Management of Extensive Central Nervous System Cladophialophora bantiana Infection in a 9-Year-Old Child.

Background: Pediatric central nervous system (CNS) phaeohyphomycosis is a rare invasive fungal infection associated with high mortality.

Methods: We describe a child with progressive neurologic symptoms whose ultimate diagnosis was Cladophialophora bantiana -associated CNS phaeohyphomycosis. We discuss her clinical presentation, medical and surgical management and review the current literature.

Eosinophilic Meningitis: Eleven-Year Experience at Texas Children's Hospital.

Eosinophilic meningitis can be caused by various etiologies and is reported mostly in tropical climates. The diagnosis is rare in the continental US, presenting challenges for management. Following a case of pediatric eosinophilic meningitis, we reviewed our 11-year experience with this diagnosis at a large US children's hospital.

Pediatric Disorders of Orthostatic Intolerance.

Orthostatic intolerance (OI), having difficulty tolerating an upright posture because of symptoms or signs that abate when returned to supine, is common in pediatrics. For example, ∼40% of people faint during their lives, half of whom faint during adolescence, and the peak age for first faint is 15 years. Because of this, we describe the most common forms of OI in pediatrics and distinguish between chronic and acute OI.

Neurodevelopmental outcome after extreme prematurity: a review of the literature.

Background: Advances in obstetric and neonatal medical care and assisted reproductive technology have increased the rates of preterm birth, decreased preterm mortality rates, and lowered the limit of viability. However, morbidity in survivors, including neurodevelopmental disabilities, has increased, especially in extremely preterm infants born at ≤25 weeks' gestation. A better understanding of the prevalence and patterns of adverse neurodevelopmental outcomes in extremely preterm infants is important for patient care, counseling of families, and research.

Low iron storage and mild anemia in postural tachycardia syndrome in adolescents.

Objective: We reported low iron storage in neurally mediated syncope (NMS). While reduced red cell mass indicative of anemia has been reported in POTS, iron indices and hemoglobin (Hb) data were not reported. We investigated whether POTS, like NMS, is associated with low iron storage and anemia.

Postural tachycardia syndrome in children and adolescents.

Postural tachycardia syndrome is a chronic condition with frequent symptoms of orthostatic intolerance or sympathetic activation and excessive tachycardia while standing, without significant hypotension. Orthostatic symptoms include dizziness, lightheadedness, blurring of vision, near faints, weakness in legs, poor concentration, nausea, and headaches. Somatic symptoms include fatigue, sleep disorder, widespread pain, abdominal pain, and menstrual irregularities.

Low iron storage in children and adolescents with neurally mediated syncope.

Objective: To investigate whether neurally mediated syncope (NMS) is associated with low iron storage or serum ferritin (SF).

Study Design: 206 children evaluated between 2000 and 2004 for probable syncope at a tertiary care Pediatric Neurology Clinic were included in a retrospective study. Serum ferritin (SF), iron, total iron binding capacity, and hemoglobin were measured prospectively after initial history taking and physical examination, along with other diagnostic testing.

Migraine and recurrent epistaxis in children.

Recurrent epistaxis is a common pediatric problem with uncertain etiology in most cases. We observed frequent complaints, or history of epistaxis in children with migraine. The aim of this study was to determine whether there is an association between epistaxis and migraine in children.
