SARS-CoV-2 antibodies among health care workers from a children's hospital.

Introduction. In Argentina, health care workers have been the first ones to receive the COVID-19 vaccine, but there are still few data on the production of anti-S IgG antibodies. Objectives.

Seroprevalence of SARS-CoV-2 antibodies among physicians from a children's hospital.

Introduction: In just a few months, coronavirus disease 2019 (COVID-19) has become a pandemic, causing millions of cases and hundreds of thousands of deaths. Due to its high infectiousness, the health care staff is even more exposed. Nevertheless, there is still very limited information about it, especially among pediatricians.

Decreased 6-Sulfatoxymelatonin Excretion in Male GH-Deficient Children and Adolescents.

Aim: To evaluate melatonin secretion in a group of untreated and treated male growth hormone (GH)-deficient children and adolescents.

Methods: We studied 44 male subjects: 8 untreated GH-deficient patients (GHDnt), 16 treated GH-deficient patients (GHDt) and 20 healthy children and adolescents as control group (CG). We measured urinary 6-sulfatoxymelatonin (6-SM) in total (24-hour samples), nocturnal (18.

New mutation in the CASR gene in a family with familial hypocalciuric hypercalcemia (FHH) and neonatal severe hyperparathyroidism (NSHPT).

A loss of calcium-sensing receptor (CASR) function due to inactivating mutations can cause familial hypocalciuric hypercalcemia (FHH) or neonatal severe hyperparathyroidism (NSHPT). NSHPT represents the most severe expression of FHH and courses as a life-threatening condition. The aim of this study was to identify and characterize a CASR mutation in a female infant brought to the health service due to dehydration, apathy, lack of breast feeding and severe hypercalcemia.
