KINGELLA KINGAE SEQUENCE TYPE 25 MENINGITIS IN AN IMMUNOCOMPETENT TODDLER: CLINICAL AND MOLECULAR APPROACH.

Kingella kingae is a cause of bacteremia, endocarditis, and the leading cause of osteoarticular infections between 6 and 48 months of life. We report on a rare case of K. kingae meningitis in the absence of endocarditis and immune deficiency in a 26-month-old boy emphasizing the distinct genomic determinants of the strain which may be of importance to the pathogenesis of the disease.

Anastrozole monotherapy further improves near-adult height after the initial combined treatment with leuprorelin and anastrozole in early-maturing girls with compromised growth prediction: results from the second phase of the GAIL study.

Background: The first phase of the GAIL study ("Girls treated with an Aromatase Inhibitor and Leuprorelin," ISRCTN11469487) has shown that the combination of anastrozole and leuprorelin for 24 months is safe and effective in improving the predicted adult height (PAH) in girls with early puberty and compromised growth prediction by +1.21 standard deviation score (SDS; +7.51 cm) compared to inhibition of puberty alone, +0.

SARS-CoV-2 seroprevalence among children in Greece during Omicron variant period.

The Omicron variant is associated with increased transmissibility, but evidence about the impact of Omicron in seropositivity of children is limited. This study aims to evaluate SARS-CoV-2 seroprevalence in children during the different variants' subperiods. A prospective multicenter seroprevalence study was conducted in 7 University public hospitals in Greece from November 2021 to August 2022 (3 subperiods: November 2021-February 2022, March 2022-May 2022, June 2022-August 2022).

Multisystem inflammatory syndrome in children (MIS-C): A nationwide collaborative study in the Greek population.

Unlabelled: Multisystem inflammatory syndrome in children (MIS-C) is a rare but severe hyperinflammatory condition that may occur following SARS-CoV-2 infection. This retrospective, descriptive study of children hospitalized with multisystem inflammatory syndrome in children (MIS-C) in 12 tertiary care centers from 3/11/2020 to 12/31/2021. Demographics, clinical and laboratory characteristics, treatment and outcomes are described.
