Background: Candida auris, an emerging multidrug-resistant yeast, has become a global concern due to its association with nosocomial outbreaks and resistance to antifungal medications. The COVID-19 pandemic has exacerbated the situation, with several outbreaks reported worldwide, including in Mexico. We describe the clinical and microbiological characteristics of a multicentric outbreak in private institutions in Mexico.

Molecular epidemiology of carbapenemase encoding genes in infections in children: a systematic review.

Background: complex is the leader pathogen for the World Health Organization's list due to the escalating prevalence of multidrug-resistant strains. Insights into the molecular characterization of carbapenemase genes in complex infections among children are scarce. To address this gap, we conducted a systematic review to describe the molecular epidemiology of the carbapenemase genes in complex infections in the pediatric population.

Case Report: Molecular Characterization of Bloodstream Infections due to Carbapenem-Resistant Acinetobacter baumannii: A Pediatric Case Series.

Acinetobacter baumannii poses a significant threat to public health due to the high rate of multidrug-resistant strains. However, information on the molecular characterization of carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infections in children is scarce. This study aimed to describe the molecular characterization of carbapenem-resistant A.

Clinical-Demographic and Laboratory Profile of the Mother-Child Binomial With Syphilis in a Tertiary-Level Hospital in Mexico.

Background: Congenital syphilis (CS) remains a major public health problem, and its incidence is increasing worldwide.

Methods: Retrospective, observational, and descriptive study of cases with CS and their mothers at a tertiary-level hospital in Mexico from 2017 to 2022. Medical records of patients with CS and a structured collection of epidemiological, clinical, and laboratory data were analyzed and classified in the Centers for Disease Control scenarios as confirmed, probable, less probable, or unlikely.

Carbapenem-Resistant Acinetobacter baumannii Infection in Children From a Third-Level Hospital in Mexico: Clinical Characteristics and Molecular Epidemiology.

Background: Acinetobacter baumannii has emerged as a threat to public health due to the high prevalence of multidrug-resistant isolates. Information regarding the clinical and molecular characterization of carbapenem-resistant A. baumannii (CRAB) infections in children is scarce.

Chryseobacterium indologenes bacteremia in children with comorbidities.

Introduction: We describe a series of pediatric cases of bacteremia, all of them with a history of heart disease, use of central venous catheter and coinfections. A review of the published literature was carried out in order to enrich the available information.

Material And Methods: Pediatric observational retrospective study in which three cases of catheter-related bloodstream infection due to Chryseobacterium indologenes were reported in a period of two years in a tertiary care hospital.

Pediatric Phaeohyphomycosis: A 44-Year Systematic Review of Reported Cases.

Background: Phaeohyphomycosis is an infection caused by pigmented fungi, which can be life-threatening in immunocompromised hosts and in disseminated disease. In adults with disseminated disease, mortality is as high as 79%. Data in children are derived from case reports and series.

Outcomes of neonates born to women with Covid-19.

Facklamia hominis pyelonephritis in a pediatric patient: first case report and review of the literature.

Background: Pyelonephritis is one of the most serious bacterial illnesses during childhood. Gram-negative organisms account for up to 90% of the cases. Gram-positive bacteria are uncommon causes of urinary tract infections, and only a few cases caused by Facklamia hominis have been reported in the literature.

Tuberculosis in Children in a Pediatric Hospital in Mexico.

Tuberculosis (TB) remains a global problem and a diagnostic challenge, especially in pediatrics. The aim of this study was to describe the clinical, microbiological, radiological, and histopathological data of TB in children. A 7-year retrospective and descriptive cohort study that included 127 patients under 18 years of age with diagnosis of active TB was conducted from 2011 to 2018 in a pediatric hospital.

Case Report: Cerebral Phaeohyphomycosis Due to Chaetomium strumarium in a Child with Visceral Heterotaxy Syndrome.

Chaetomium sp. is a mold, member of the phylum Ascomycota. Clinical disease in humans is rare, particularly in children, for which only five cases have been reported.

Disseminated Coccidioidomycosis as the First Presentation of a C-Terminal NFKB2 Pathogenic Variant: A Case Report and Review of the Literature.

Introduction: Although most cases of coccidioidomycosis are subclinical or self-limited respiratory disease, 1% lead to extrathoracic dissemination and become fatal, especially in patients with an associated immunodeficiency. Up to 30%-50% of patients with defects in cell-mediated immunity, those with AIDS and recipients of solid-organ transplants, may develop disseminated coccidioidomycosis (DC). Within the primary immunodeficiencies, an uncommon group is caused by C-terminal NFKB2 pathogenic variants.

A 20-year retrospective study of osteoarticular tuberculosis in a pediatric third level referral center.

Purpose: The objective of the present study is to describe the clinical, diagnostic, radiological and therapeutic aspects of osteoarticular tuberculosis (OATB) in patients in a tertiary pediatric hospital, to know if the diagnosis of OATB in pediatrics is a challenge due to its insidious clinical presentation.

Methods: A retrospective, descriptive study of the cases of Tuberculosis (TB) in children was carried out. A total of 159 cases met the condition for the analysis.

Case Report: Granulomatous Amebic Encephalitis due to Acanthamoeba spp. in an Immunocompetent Pediatric Patient.

Granulomatous amebic encephalitis (GAE) caused by Acanthamoeba is a rare infection with central nervous system (CNS) involvement usually with fatal consequences. Currently, information regarding GAE in children is scarce and is limited only to case reports and case series. A 13-year-old immunocompetent male patient with a 6-month history of progressive and intermittent headaches presented to our institution.

Co-infection with Streptococcus anginosus and Mycobacterium tuberculosis in an immunocompetent pediatric patient. A case report.

Background: Simultaneous infection in tuberculosis (TB) is rare. The mixed infection between Streptococcus anginosus group (SAG) and M. tuberculosis (MTB) has not been reported in children.

Case Report: Chest Wall Tuberculosis without Pulmonary Involvement in Three Pediatric Immunocompetent Patients.

Primary rib cage tuberculosis (TB) is an infrequent form of presentation and represents 1% of all cases of osteoarticular TB. We report three cases of children who were previously healthy and who began with swelling of the anterior surface of the rib as initial manifestation of TB. The most important clinical presentations in this series were swelling and pain, with lytic lesions and a soft tissue mass in image studies simulating oncologic pathologies.
