Secondary pseudohypoaldosteronism: a 15-year experience and a literature review.

Background: Secondary pseudohypoaldosteronism (S-PHA) is a rare condition resulting from renal tubular resistance to aldosterone in children with urinary tract infection (UTI) and/or nephrourological malformations. It is characterized by nonspecific symptoms but with the potential for life-threatening complications. We aim to evaluate the clinical manifestations, diagnostic approach, and therapeutic interventions in children with S-PHA, along with a review of recent publications.

Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography.

Background: Takayasu arteritis is a large-vessel vasculitis which affects large-caliber elastic arteries, primarily the aorta and its main branches. It mainly affects women between 20-30 years, so it is rare in children.

Case Report: We describe the case of a 15-year-old female who was followed up since she was 9 years old due to celiac disease.

[Intracranial hypotension syndrome in a pediatric patient with Marfan syndrome].

Intracranial hypotension syndrome (IHS) is attributed to reduced cerebrospinal fluid (CSF) pressure. It may be spontaneous or secondary to a history of trauma or systemic disease. We present the case of an 11-year-old boy, with medical history of Marfan syndrome, with orthostatic headache and persistent vomiting (12 hours) following a fall on the sacrococcygeal region.

Retrospective study on the effectiveness and safety of the shortened 5- to 7-day antibiotic regimen for acute streptococcal pharyngotonsillitis compared to the classic 10-day regimen.

Introduction: Antibiotherapy regimens for management of acute streptococcal pharyngitis traditionally last 10 days, but the development of resistance to different antimicrobials has motivated the exploration of shorter courses.

Material And Methods: We selected patients given a diagnosis of streptococcal pharyngitis in 2 paediatric caseloads of 1 primary care centre between June 2016 and April 2020. We compared outcomes in patients treated with 8- to 10-day courses versus 5- to 7-day courses.

[Allan-Herndon-Dudley syndrome: a diagnosis to rule out in any male infant with undiagnosed hypotonia].

Unlabelled: Allan-Herndon-Dudley syndrome is a rare X-linked genetic disorder, caused by a deficiency of the monocarboxylate transporter 8 (MCT8), a specific transporter of thyroid hormones, with functions mainly at the brain level. The syndrome produces an early onset of severe neurological disorder, in which hypotonia predominates.

Objective: To present a rare case with an unexpected diagnosis, highlighting the usefulness of requesting a complete thyroid profile in every hypotonic male infant without a specific cause.
