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.

Background: Ehrlichia chaffeensis is responsible for most cases of human ehrlichiosis, an acute febrile tick-borne disease. This clinical entity is more commonly reported in adults from the United States. Therefore, it is of special interest to characterize this disease in children, given that very few cases in children have been reported outside of this country.

Recent studies suggest that the introduction of antiretroviral agents such as integrase strand transfer inhibitors (INSTI) may lead to weight gain in people living with HIV (PLHIV). In this retrospective observational study, we report the weight changes observed in virologically suppressed HIV patients after 12 months of switching to bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF) due to a national change in public policy in Mexico. Patients on prior regimens based on TDF/FTC or ABC/3TC plus non-nucleoside retrotranscriptase inhibitor, INSTI, or protease inhibitor were included.

Introduction: People living with human immunodeficiency virus (PLHIV) may suffer more severe symptoms of coronavirus disease 2019 (COVID-19) due to their immunocompromised status, even if they are undetectable. Human immunodeficiency virus (HIV) infection has been reported as an independent factor associated with higher mortality in patients with COVID-19. The present study aims to describe the clinical characteristics of PLHIV and COVID-19 in one center in Mexico.

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.

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.
