RESUMO
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.

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. baumannii infections in children from a hospital in Mexico. A retrospective study was conducted during the period 2017-2022. Clinical and demographic data were collected from the clinical records. Mass spectrometry was used for the identification of the strains. To confirm A. baumannii strains, a polymerase chain reaction (PCR) method was applied using a gyrB sequence. The carbapenemase-encoding resistance genes were detected by PCR. Six cases of CRAB were documented, including five in neonates. The median intensive care unit stay was 20 days, and all cases had an invasive medical device. Half of the patients had at least one medical condition. A high prevalence of coresistance was observed in most of the antibiotic groups. Three of the six strains coharbored carbapenemase genes: blaOXA-51, blaOXA-24, and blaIMP. Mortality was reported in two neonate patients. The present study shows a high rate of coharboring blaOXA-51, blaOXA-24, and blaIMP-1, which has a direct impact on therapeutic decisions. Implementation of antimicrobial stewardship programs is urgent to stop the spread of this microorganism.

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. Our study aimed to describe the clinical and molecular characteristics of CRAB infections in children from a third-level center in Mexico. METHODS: Consecutive cases of CRAB infections were documented during 2017-2022. Clinical and demographic data were collected from clinical records. Mass spectrometry was used for the identification of the isolates. The identification of A. baumannii strains was confirmed by conducting a polymerase chain reaction (PCR) assay targeting the gyrB sequence. In addition, the carbapenemase-encoding resistance genes were detected by PCR. RESULTS: Twenty-one cases of CRAB infections were documented: 76% female and 62% were neonates. The median hospital length of stay at the time of positive culture was 37 days (interquartile range, 13-54). Sixty-four percent of the isolates were recovered from bronchial secretions. A co-resistance rate greater than 60% was observed for most groups of antibiotics. All carbapenem-resistant isolates carried blaOXA-24 genes. BlaIMP genes were detected in half of the cases, with all strains co-harboring blaOXA-24 genes. CONCLUSIONS: The present study demonstrated a high proportion of CRAB infections in the neonatal population, a high prevalence of co-resistance to antibiotics, and a high rate of isolates carrying blaOXA-24 and blaIMP genes. CRAB is a significant concern due to the mortality rate and the lack of therapeutic alternatives; implementing infection prevention and control programs is urgent to stop the spread of carbapenem-resistant A. baumannii.

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.

Background: Weeksella virosa is one of the two species of the genus Weeksella. Clinical disease due to this bacterium in humans is rare, for which only nine cases have been reported in the literature. Case report: A 4-year-old male patient was diagnosed with a left orbit rhabdomyosarcoma Stage III and was admitted to a northeast third level referral center in Mexico. Aerobic, non-pigmented, Gram-negative rod was isolated from a blood culture. W. virosa was identified by Sensititre™ ARIS. This organism has been described in cases of spontaneous bacterial peritonitis, sepsis, pneumonia, ventriculitis, and urinary tract infection. Conclusions: Clinicians should consider the diagnosis of W. virosa bacteremia in cases involving immunocompromised patients with oral lesions, although it is infrequent. To the best of our knowledge, this is the first clinical report of W. virosa bacteremia described in an immunocompromised pediatric patient.
Introducción: Weeksella virosa es una de las dos especies del género Weeksella. En los humanos, los reportes de infección por este microorganismo son raros. Solo se han reportado nueve casos en la literatura. Caso clínico: Paciente masculino de 4 años con diagnóstico de rabdomiosarcoma embrionario de órbita izquierda en estadio III, que fue atendido en un hospital de tercer nivel en el noreste de México. Se realizó un hemocultivo, a partir del cual se aisló un bacilo gramnegativo aerobio, no pigmentado. Se identificó W. virosa mediante Sensititre™ ARIS. Este microorganismo ha sido descrito en casos de peritonitis bacteriana espontánea, sepsis, neumonía, ventriculitis e infección del tracto urinario. Conclusiones: Aunque los casos de bacteriemia por W. virosa son raros, los clínicos deben considerar este agente en pacientes inmunocomprometidos con lesiones orales. Hasta donde se conoce, este es el primer caso que se describe de bacteriemia por W. virosa en un paciente pediátrico inmunocomprometido.

Pertussis continues to be responsible for a significant disease burden worldwide. Although immunization practices have reduced the occurrence of the disease among children, waning vaccine- and infection-induced immunity still allows the disease to affect adolescents and adults who, in turn, can transmit the disease to non-immunized or partially immunized infants. This document is the result of a meeting in Mexico City of international experts who analyzed recent medical information in order to establish the current status of the epidemiology, diagnosis and surveillance of pertussis and, especially, the value of the dTpa booster dose in adolescents and adults as a pertussis prevention strategy in Mexico.

La tos ferina sigue siendo responsable de una carga de enfermedad importante en el mundo. Aunque la implementación del uso de la vacuna contra esta enfermedad ha disminuido en gran medida el número de casos en la población pediátrica, se ha observado que la inmunidad inducida por la vacuna y por la infeccion natural disminuye con el tiempo lo que hace nuevamente susceptibles a adolescentes y adultos jóvenes que pueden transmitir la enfermedad a lactantes no inmunizados o con esquema de vacunación incompleto. Este documento, resultado de la reunión de un grupo internacional de expertos en la Ciudad de México, ha analizado la información médica reciente para establecer el estado actual de la epidemiología, diagnóstico, vigilancia y, especialmente, el valor de la dosis de refuerzo con dTpa en adolescentes y adultos como estrategia de prevención de tos ferina en México.
