POCUS for Infectious Enteritis-A Retrospective Case Series Analysis.

Introduction: The abdominal pain associated with diarrhea can be difficult to distinguish from appendicitis. We present a case series of all children found on pediatric emergency department point-of-care ultrasound (POCUS) to have right-sided bowel wall edema.

Methods: Over the study period June 2020 through September 2023, POCUS images were collected by a pediatric emergency physician with 6 years of experience with POCUS.

Reproducibility and Refinement of Urinary LH in the Screening of Progressive Puberty in Girls.

Context: First-voided urinary LH (FVU-LH) has been suggested as an alternative to GnRH stimulation test for detection of precocious puberty.

Objective: To evaluate the reproducibility of FVU-LH, its correlation with basal and GnRH-stimulated gonadotropins, and its diagnostic value for differentiating progressive from nonprogressive puberty.

Design And Participants: Clinical and endocrine data were obtained from the medical records of 95 girls with suspected progressive puberty who underwent 2 consecutive FVU-LH tests.

Neural tube closure depends on nitric oxide synthase activity.

Neural tube (NT) closure is a multifactorial process that involves yet unresolved molecular mechanisms. It had been shown previously that high levels of nitric oxide (NO) block the process of NT closure in the chick embryo by inhibiting methionine synthase (MS). The MS inhibition and its effect on NT closure could be alleviated by folic acid, suggesting the involvement of the folate-methionine pathway in the process.

Anatomical basis of sleep-related breathing abnormalities in children with nasal obstruction.

Objective: To define, in a group of children with nasal obstruction, the anatomical differences that differentiate those with quiet, unobstructed nocturnal respiration from those with obstructive sleep-related breathing abnormalities (snoring and obstructive sleep apnea).

Design: Case series.

Patients: Fifty-nine children aged 3 to 13 years (35 boys and 24 girls) with nasal obstruction and without tonsillar hypertrophy, known craniofacial syndromes, or neuromuscular diseases were included in the study.
