Urinary tract infection caused by bacterial pathogens of the respiratory tract in children.

BACKGROUND: Urinary tract infections (UTIs) caused by bacterial pathogens of the respiratory tract such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are rare and little is known about their clinical features and potential host risk factors. The aim of this study is to reveal their clinical characteristics. METHODS: We conducted a retrospective descriptive study on pediatric UTI due to S. pneumoniae, Haemophilus spp., or M. catarrhalis at a tertiary-care pediatric hospital. Pediatric patients diagnosed with UTI between 2002 and 2020 were included. Patient demographics, laboratory data, and microbiological findings were extracted from their electronic medical records and the infectious disease surveillance system. RESULTS: Among 46,332 urine samples, 76 bacteriuria (0.16%) and 22 UTI (0.05%) events due to the targeted species were identified (S. pneumoniae, n = 7, and Haemophilus spp., n = 15). Of the patients, 17 (85%) had underlying urinary tract abnormalities and 13 (60%) had vesicocutaneous fistula. All the UTI episodes caused by S. pneumoniae and Haemophilus spp. occurred after cystostomy. All the patients had satisfactory clinical outcomes. CONCLUSIONS: Although S. pneumoniae and Haemophilus spp. are rare causes of UTIs in children, they could be the true causative bacteria of UTI, particularly in the patients with urinary tract abnormalities and vesicocutaneous fistulas. Thus, clinicians should not ignore these pathogens as contaminations in special populations.

Treatment odyssey to epilepsy surgery in children with focal cortical dysplasia: Risk factors for delayed surgical intervention.

OBJECTIVE: To elucidate the patient's journey to epilepsy surgery and identify the risk factors contributing to surgical delay in pediatric patients with drug-resistant epilepsy (DRE) due to focal cortical dysplasia (FCD). METHODS: A retrospective review was conducted of 93 pediatric patients who underwent curative epilepsy surgery for FCD between January 2012 and March 2023 at a tertiary epilepsy center. The Odyssey plot demonstrated the treatment process before epilepsy surgery, including key milestones of epilepsy onset, first hospital visit, epilepsy diagnosis, MRI diagnosis, DRE diagnosis, and surgery. The primary outcome was surgical delay; the duration from DRE to surgery. Multivariate linear regression models were used to examine the association between surgical delay and clinical, investigative, and treatment characteristics. RESULTS: The median age at seizure onset was 1.3 years (interquartile range [IQR] 0.14-3.1), and at the time of surgery, it was 6 years (range 1-11). Notably, 46% experienced surgical delays exceeding two years. The Odyssey plot visually highlighted that surgical delay comprised a significant portion of the patient journey. Although most patients underwent MRI before referral, MRI abnormalities were identified before referral only in 39% of the prolonged group, compared to 70% of the non-prolonged group. Multivariate analyses showed that delayed notification of MRI abnormalities, longer duration from epilepsy onset to DRE, older age at onset, number of antiseizure medications tried, and moderate to severe intellectual disability were significantly associated with prolonged surgical delay. CONCLUSION: Pediatric DRE patients with FCD experienced a long journey until surgery. Early and accurate identification of MRI abnormalities is important to minimize surgical delays.
