Covid-19 mortality in children and adolescents in Mexico.

Objective: To estimate Covid-19 and pre-pandemic low respiratory infection (LRI) mortality in children and adolescents in Mexico.

Materials And Methods: We estimated the percentage of total mortality attributable to Covid-19 (95% confidence intervals; 95%CI) and made the corresponding estimates for pre-pandemic LRI mortality.

Results: In 2019, LRIs represented 8.

Clinical and Epidemiological Characteristics of Paediatric Patients Diagnosed with COVID-19 in a Tertiary Hospital in Mexico City.

COVID-19 affects the paediatric population less frequently than adults. A retrospective study was performed in a tertiary paediatric hospital in Mexico City in children <18 years of age who were hospitalized with a positive reverse transcription-polymerase chain reaction for SARS-CoV-2. Included in the study were 86 patients with a median age of 10 years old (IQR 2.

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.

First clinical isolate of Escherichia coli harboring mcr-1 gene in Mexico.

Our aim in this report was to describe the characteristics of the first clinical isolate of Escherichia coli (EC-PAG-733) harboring the mcr-1 gene found in Mexico. This isolate was obtained from a fecal sample from a young child with an oncological condition. We obtained the whole-genome sequence using next-generation sequencing and analyzed the sequence by bioinformatics tools.

Osteitis secondary to BCG vaccine in immunocompetent patients: Three case reports.

Rationale: Osteitis corresponds to a rare but potentially serious complication reported in pediatric population after the application of the Bacillus Calmette-Guerin (BCG) vaccine. In the present study, 3 clinical cases associated with this entity are reported.

Patient Concerns: The 1st case corresponds to a 1-year-old female patient who presented an increase in the volume of the right pelvic limb after BCG application.

Carbapenemase-producing Enterobacteriaceae in Mexico: report of seven non-clonal cases in a pediatric hospital.

Background: Carbapenemases-producing Enterobacteriaceae (CPE) are a worldwide public health emergency. In Mexico, reports of CPE are limited, particularly in the pediatric population. Here, we describe the clinical, epidemiological, and molecular characteristics of seven consecutive cases in a third-level pediatric hospital in Mexico City over a four-month period during 2016.
