Herein, we conducted descriptive dynamic epidemiology, characteristic analysis and geographical distribution study of pediatric TB inpatients in Southwest China for more than 20 years. METHODS: Patients with pediatric TB were recruited from October 2002 to September 2022 in Southwest of China based on etiology or clinical confirmation...

A major obstacle in improving survival in pediatric T-cell acute lymphoblastic leukemia is understanding how to predict and treat leukemia relapse in the CNS. Leukemia cells are capable of infiltrating and residing within the CNS, primarily the leptomeninges, where they interact with the microenvironment and remain sheltered from systemic treatment. These cells can survive in the CNS, by hijacking the microenvironment and disrupting normal functions, thus promoting malignant transformation. While the protective effects of the bone marrow niche have been widely studied, the mechanisms behind leukemia infiltration into the CNS and the role of the CNS niche in leukemia cell survival remain unknown...

BACKGROUND: Cerebral vasospasm is commonly associated with adult aneurysmal subarachnoid hemorrhage but can develop in children. The standard vasospasm treatment includes induced hypertension, avoidance of hypovolemia, systemic use of the calcium channel blocker (CCB) nimodipine, and cerebral angiography for intraarterial therapy. Emerging treatments in adults, such as intraventricular CCB administration, have not been investigated in children. This study demonstrates the successful use of an intraventricular CCB in a pediatric patient with refractory vasospasm secondary to meningitis...

Macrocephaly is defined as an abnormal increase in head circumference greater than two standard deviations above the mean for a given age and sex. We present the case of a 16-month-old boy with congenital progressive macrocephaly, who was referred to our hospital for a ventriculoperitoneal shunt placement for external hydrocephalus diagnosed at 13 months of age. The patient had a febrile seizure 12 hours after the shunt was placed and the emergency CT exam revealed collapsed ventricles and a right frontal subdural collection, suggestive of an over-drainage and intracranial hypotension...

BACKGROUND: The introduction of varicella vaccines into routine pediatric immunization programs has led to a considerable reduction in varicella incidence. However, there have been reports of varicella, herpes zoster, and meningitis caused by the vaccine strain of varicella-zoster virus (VZV), raising concerns. Establishing the relationship between the wild-type and vaccine strains in VZV infections among previously vaccinated individuals is crucial. Differences in the single nucleotide polymorphisms (SNPs) among vaccine strains can be utilized to identify the strain...

(1) Introduction: This pilot study aimed to analyze neurofilament light chain levels in cerebrospinal fluid (cNfL) in a cohort of children with different acute nontraumatic neurological conditions. (2) Methods: This prospective observational cohort study consisted of 35 children aged 3 months to 17 years and was performed from November 2017 to December 2019. Patients' clinical data were reviewed, and patients were assigned to the following groups: n = 10 (28.6%) meningitis, 5 (14.3%) Bell's palsy, 7 (20.0%) febrile non-CNS infection, 3 (8...

BACKGROUND: Enterococcal meningitis in children is rare, and its clinical presentation, laboratory characteristics and outcomes are not well defined. METHODS: We conducted a retrospective analysis of Enterococcal meningitis cases during 2002-2023 at our tertiary center. RESULTS: We identified 10 cases in children aged 2 weeks to 15 years (median age: 8 months). Seven children were males and 9 had comorbidities, including a ventriculoperitoneal shunt in 5 children...

AIM: A low Glasgow Coma Scale Score (GCS) on admission is a known predictor of poor outcome from childhood bacterial meningitis. In turn, the factors associated with the admission GCS are less known. Our aim was to identify them, both for clinical alerts of reserved prognosis and to find potential targets for intervention. METHODS: This study is a secondary analysis of data collected prospectively in Angola and in Latin America between 1996 and 2007. Children with bacterial meningitis were examined on hospital admission and their GCS was assessed using the age-adjusted scale...

Our goal was to identify predictors of invasive bacterial infection (ie, bacteremia and bacterial meningitis) in febrile infants aged 2 to 6 months. In our multicenter retrospective cohort, older age and lower temperature identified infants at low risk for invasive bacterial infection who could safely avoid routine testing.

BACKGROUND: Pediatric coronavirus disease 2019 infection usually presents with respiratory and gastrointestinal symptoms. In this report we present fulminant meningitis as the main presentation of coronavirus disease 2019 without major signs and symptoms of other organs' involvement in 3 infants. CASES: The first case was a 4 months Iranian male infant with fulminant meningitis as the main presentation of coronavirus disease 2019 without other organ involvement...

PURPOSE: Posterior fossa surgeries for pediatric tumors pose challenges in achieving optimal dural repair and duraplasty is usually required. Autografts, allografts, xenografts, and synthetic substitutes can be used for duraplasty. Autologous cervical fascia can be a safe and reliable graft option for duraplasty after posterior fossa surgeries. This study aims to investigate the outcomes of duraplasty with autologous cervical fascial graft in children after posterior fossa surgery for pediatric brain tumors...

Clinical symptoms are rarely evident in children, thus making a diagnosis is a challenge. Antibiotic therapy should be started timely to ensure the avoidance of significant morbidity and mortality. This study aims to assess the outcomes, mortality, and symptomatology of children presenting with BM in allied hospitals of Rawalpindi Medical University, Pakistan. Methods It is a cross-sectional study employing a sample size of 201, conducted at the Allied Hospitals of Rawalpindi Medical University, Pakistan from a period of January 2023 to August 2023...

OBJECTIVES: Hyperpyrexia has been associated with a greater prevalence of bacterial infections in the pediatric population, which prior to routine childhood vaccinations, has led to invasive testing and empiric antibiotic use for urinary tract infections, bacterial pneumonia, bacteremia, and bacterial meningitis. Since the implementation of routine childhood vaccinations, the prevalence of serious bacterial infections (SBIs) has declined. This study aims to determine if there is an association between hyperpyrexia and serious bacterial infections in well-appearing febrile pediatric patients presenting to the emergency department (ED)...
