Urinary Tract Infection in Children and the Potential Role of Pivmecillinam as a Treatment Option.

We investigated the potential role of pivmecillinam in the treatment of urinary tract infections in children. Among 351 children (0-6 years) with urinary tract infections, 83% could be treated with pivmecillinam following urine culture. Resistance was highest in infants (0-3 months) caused by the high prevalence of Enterococcus faecalis.

incidence, phenotype, and severity in children and adolescents in Denmark before, during, and after the COVID-19 pandemic: a nationwide multicentre population-based cohort study.

Background: infections resurged globally in 2023-2024 after a three-year decline during the COVID-19 pandemic. We explored the incidence and severity of infections in children and adolescents before, during, and after the pandemic.

Methods: This nationwide, population-based cohort study included all Danish children and adolescents aged 0-17 years with a positive PCR test from May 1, 2016, to April 30, 2024.

Proteomic profiling reveals diagnostic signatures and pathogenic insights in multisystem inflammatory syndrome in children.

Multisystem inflammatory syndrome in children (MIS-C) is a severe disease that emerged during the COVID-19 pandemic. Although recognized as an immune-mediated condition, the pathogenesis remains unresolved. Furthermore, the absence of a diagnostic test can lead to delayed immunotherapy.

Host RNA Expression Signatures in Young Infants with Urinary Tract Infection: A Prospective Study.

Early diagnosis of infections in young infants remains a clinical challenge. Young infants are particularly vulnerable to infection, and it is often difficult to clinically distinguish between bacterial and viral infections. Urinary tract infection (UTI) is the most common bacterial infection in young infants, and the incidence of associated bacteremia has decreased in the recent decades.

Fatal case of hospital-acquired hypernatraemia in a neonate: lessons learned from a tragic error.

A 3-week-old boy with viral gastroenteritis was by error given 200 mL 1 mmol/mL hypertonic saline intravenously instead of isotonic saline. His plasma sodium concentration (PNa) increased from 136 to 206 mmol/L. Extreme brain shrinkage and universal hypoperfusion despite arterial hypertension resulted.

Prevalence of SARS-CoV-2-Antibodies in Danish Children and Adults.

In Denmark, severe acute respiratory syndrome coronavirus 2 antibodies were assessed in a cross-sectional study among 1033 children visiting pediatric departments and 750 blood donors in June 2020, using a point-of-care test. Antibodies were detected in 17 children (1.6%) and 15 blood donors (2.

A Weighted Genetic Risk Score of Adult Glioma Susceptibility Loci Associated with Pediatric Brain Tumor Risk.

Genetic risk score (GRS) is used to demonstrate the genetic variants contributing to the polygenic architecture of complex diseases. By using a GRS, we have investigated the additive impact of the known adult glioma susceptibility loci on the pediatric brain tumor (PBT) risk and assessed the proportion of PBT heritability attributable to these susceptibility loci. A GRS was generated for PBTs based on the alleles and associated effect sizes derived from a previously published genome-wide association study on adult glioma.

[Severe haemolytic anaemia and hepatitis in the course of Epstein-Barr virus infection].

Epstein-Barr virus (EBV) is globally prevalent and in adolescents mostly observed as infectious mononucleosis. Abnormal liver blood tests are common, whereas more serious hepatitis is less prevalent. Autoimmune haemolytic anaemia may also occur in the course of this infection.

[Rhabdomyolysis after isotretinoin treatment in a 17-year-old male].

Rhabdomyolysis is a rare, but known complication to treat-ment with systemic isotretinoin in patients with acne and can lead to severe kidney damage. In our case report a 17-year-old male, exercising moderately, developed rhab-domyolysis without kidney injury after two-month treatment with isotretinoin 20 mg daily. He complained of some muscle pain and was treated according to guidelines for rhabdomyolysis with no sequelae.

EEG with extreme delta brush in young female with methotrexate neurotoxicity supports NMDA receptor involvement.

Sub-acute neurotoxicity is a well-known complication to high-dose and intrathecal methotrexate (MTX) treatment of children with leukemia. Symptoms can be treated safely by dextromethorphan, a non-competitive antagonist to N-methyl-D-aspartic acid receptor (NMDAR). In a female with subacute MTX neurotoxicity, we observed an electroencephalographic (EEG) with extreme delta brush.

[Epidural abscess secondary to sinusitis].

Approximately 0.5-2% of upper viral infections are com-licated by secondary acute bacterial sinusitis and may in rare cases evolve into more serious complications such as meningitis and intracranial abscess. Symptoms are often subtle and nonspecific as fever, headache, scalp tenderness, nausea and altered mental status.

Prenatal and Postnatal Medical Conditions and the Risk of Brain Tumors in Children and Adolescents: An International Multicenter Case-Control Study.

Background: Previous studies have evaluated the effect of medical diagnostic radiation on brain tumors. Recent cohort studies have reported an increased risk associated with exposure to head CT scans.

Methods: Information regarding medical conditions, including prenatal and postnatal exposure to medical diagnostic radiation, was obtained from CEFALO, a multicenter case-control study performed in Denmark, Norway, Sweden, and Switzerland through face-to-face interview.

Common genetic variations in cell cycle and DNA repair pathways associated with pediatric brain tumor susceptibility.

Knowledge on the role of genetic polymorphisms in the etiology of pediatric brain tumors (PBTs) is limited. Therefore, we investigated the association between single nucleotide polymorphisms (SNPs), identified by candidate gene-association studies on adult brain tumors, and PBT risk.The study is based on the largest series of PBT cases to date.

A multinational case-control study on childhood brain tumours, anthropogenic factors, birth characteristics and prenatal exposures: A validation of interview data.

Little is known about the aetiology of childhood brain tumours. We investigated anthropometric factors (birth weight, length, maternal age), birth characteristics (e.g.

CCDC26, CDKN2BAS, RTEL1 and TERT Polymorphisms in pediatric brain tumor susceptibility.

The role of genetic polymorphisms in pediatric brain tumor (PBT) etiology is poorly understood. We hypothesized that single nucleotide polymorphisms (SNPs) identified in genome-wide association studies (GWAS) on adult glioma would also be associated with PBT risk. The study is based on the Cefalo study, a population-based multicenter case-control study.
