Pediatric tumefactive multiple sclerosis case (with baló-like lesions), diagnostic and treatment challenges.

Background: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system, rare during childhood. MS variations, like tumefactive MS and Balo concentric sclerosis, constitute puzzling to treat diagnostic dilemmas for pediatric patients. Differential diagnosis, mainly from brain tumors, is an absolute necessity.

Pneumococcal meningitis in Greece: A retrospective serotype surveillance study in the post-PCV13 era (2010-2020).

Background: As Greece is a country which has introduced the 13-valent pneumococcal conjugate vaccine (PCV13) both in the infant and in the adult immunization programs, the aim of the study was to investigate age-specific and serotype-specific trends of pneumococcal meningitis over an 11-year period (2010-2020).

Materials And Methods: Data are reported from pneumococcal meningitis cases [notified to the National Public Health Organization (NPHO)], with clinical samples and bacterial isolates sent for pneumococcal identification and serotyping at the National Meningitis Reference Laboratory (NMRL). Pneumococcal identification was performed directly on clinical samples or bacterial isolates by multiplex PCR (mPCR) assay, while serotyping was carried out by application of the Capsular Sequence Typing (CST) method with the combination of single tube PCR assays.

Pericarditis Following Recovery From COVID-19 Infection in a 15-Year-Old Boy: A Postinflammatory Immune-Mediated Presentation or a New-Onset Autoimmune Disease.

As the COVID-19 pandemic evolves, the medical community continues to report a variety of clinical manifestations of SARS-CoV-2 in the pediatric population. Although younger age groups experience less severe disease, attention is given to the immunologic manifestations of the disease. Pericarditis is a rare cardiac complication of COVID-19 infection.

Miller Fisher Syndrome Triggered by Infections: A Review of the Literature and a Case Report.

Aim: We reported a case of Miller Fisher syndrome following a breakthrough varicella zoster virus infection in an otherwise healthy 6-year-old male. The objective of this review was to summarize the infectious etiologic agents known to trigger Miller Fisher syndrome.

Methods: Review of the literature on infections associated with Miller Fisher syndrome.

Methods: Review of the literature on infections associated with Miller Fisher syndrome.

Susceptibility patterns of uropathogens identified in hospitalized children.

Background: Urinary tract infection (UTI) is the most common serious bacterial infection in childhood. The aim of the present study was therefore to identify the organisms responsible for community-acquired febrile UTI in children, to investigate their susceptibility to commonly used antibiotics, and to identify possible risk factors for antibiotic resistance.

Methods: A total of 284 children (male, 38%; female, 62%), who were hospitalized due to a community-acquired UTI over a 5 year period in a general district hospital of southern Greece, were enrolled in the study.

Review and case report demonstrate that spontaneous spinal epidural abscesses are rare but dangerous in childhood.

Aim: A spinal epidural abscess (SEA) is a rare paediatric bacterial infection, with possible devastating neurological sequelae. We explored localisation in the cervical segment, which is unusual, but more dangerous, than other SEAs.

Methods: We describe 22 cases (12 male) of paediatric SEAs without risk factors: 21 from a literature search from 2000 to 2017 and a 30-month-old boy with a spontaneous cervical SEA due to Group A Streptococcus.

ROTASCORE Study: epidemiological observational study of acute gastroenteritis with or without rotavirus in Greek children younger than 5 years old.

We present the results of a prospective multi-center, community-based epidemiological observational study regarding the clinical burden of pediatric rotavirus gastroenteritis (PRG) in Greece.
