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.

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.

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.

Reliability of transvaginal ultrasound in detecting first trimester pregnancy abnormalities.

Objective: To evaluate the reliability of transvaginal ultrasound (US) and human chorionic gonadotropin (hCG) levels in detecting early abnormalities and predicting outcome of pregnancy.

Patients: One hundred thirty-two patients were studied, of which 113 had an intrauterine pregnancy and 19 had an ectopic pregnancy (EP).

Results: In 78 with singleton normal pregnancies, US revealed a normal crown-rump length, heart motion, and hCG levels between 1,000 to 107,000 mIU/mL.
