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. RESULTS: One hundred eighty cases were diagnosed with a compatible definition of congenital syphilis, and we identified 43 (21.21%) confirmed proven. Among those proven cases, 15.6% had hematological, 13.3% skin, 12.2% liver, 6.7% pulmonary, 6.6% neurological, 5.8% eye, 5.6% bone, and 0.6% hearing involvements. According to the clinical stages of maternal syphilis, 119 (66.1%) were in the late latent phase, 49 (27.2%) in the early latent phase, 7 (3.9%) in the secondary stage, and 5 (2.8%) in the primary stage. Mothers with tertiary syphilis were not detected. CONCLUSION: Regardless of negative antenatal screening, health care workers should consider the diagnosis of congenital syphilis. Infants are still undiagnosed at birth, and only a tiny percentage exhibits symptoms. The wide range of clinical manifestations of this preventable infection can be misdiagnosed for various other diseases, causing diagnostic delays that can have serious consequences.

Chryseobacterium indologenes bacteremia in children with comorbidities / Bacteriemia por Chryseobacterium indologenes en niños con comorbilidades

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. The analysis was performed with the cases previously reported in the literature. Results Three cases were reported in our center in a period of two years. We found 26 cases reported in the literature. Overall mortality was 26.92% (7/26). Conclusions This microorganism with characteristics of multidrug resistance is associated with the use of medical devices in hospitalized patients. Early identification of this pathogen is crucial to starting treatment (AU)

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. CASE PRESENTATION: A five-year-old girl with tracheostomy and gastrostomy and past medical history of congenital lymphangioma presented with a two-week history of with intermittent fever, frequent urination, and vesical tenesmus. Diagnosis of pyelonephritis was made. Urine culture reported colonies with alpha-hemolysis in blood agar at 48-h of incubation and Facklamia hominis was identified by MALDI-TOF. The patient was successfully treated with gentamicin. CONCLUSIONS: This is the first reported case of pyelonephritis by Facklamia hominis in a child, and the second involving infection in a pediatric patient. Although this pathogen is uncommon, current treatment of F. hominis is a challenge for physicians. This case illustrates the requirement to standardize identification and treatment of care to avoid treatment failure and antimicrobial resistance.

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. MATERIALS AND METHODS: We performed a literature search of core databases. Written informed consent for the study and for publication was obtained. CASE PRESENTATION: A 7-year-old Mexican girl, eldest of 3 sisters, no relevant family history, and a history of recurrent upper respiratory infections and alopecia totalis was admitted with DC involving pulmonary, soft tissue, skin, bone and joint compromise. The immunodeficiency assessment showed low IgM and NK cells. We found an NFKB2 de novo heterozygous nonsense mutation of c.2611C>T (p.Gln871*). She was treated with liposomal amphotericin B and itraconazole with surgical debridement. The clinical phenotype of this primary immunodeficiency is characterized by antibody deficiency and associated broncho-pulmonary predisposition to infection, but moreover also opportunistic infections and autoimmunity, most recognizable alopecia and adrenocorticotropic hormone-deficiency. After 1 year of her discharge, she continues under surveillance with antifungal therapy with itraconazole and replacement intravenous immunoglobulin until today. CONCLUSION: This is the first case report of DC in a patient with an NFKB2 pathogenic variant and it illustrates the importance of screening for primary immunodeficiencies in patients with disseminated fungal infections.
