Gut microbiota in preterm infants receiving breast milk or mixed feeding.

Background: Preterm birth is the leading cause of mortality in newborns, with very-low-birth-weight infants usually experiencing several complications. Breast milk is considered the gold standard of nutrition, especially for preterm infants with delayed gut colonization, because it contains beneficial microorganisms, such as and .

Aim: To analyze the gut microbiota of breastfed preterm infants with a birth weight of 1500 g or less.

Molecular epidemiology and drug resistance of Mycobacterium tuberculosis in a tertiary care hospital in northeastern Mexico.

Introduction: Tuberculosis (TB) is a re-emerging disease considered a public health concern. In the present study, we analyzed the epidemiology and drug resistance of Mycobacterium tuberculosis strains isolated from patients with pulmonary TB.

Methodology: Mycobacterium tuberculosis isolates (n = 190) were obtained from patients with pulmonary TB admitted to Dr.

Disseminated gonococcal disease in pediatrics: Case report and review of the literature.

Hematogenous spread of Neisseria gonorrhoeae, a sexually transmitted pathogen, results in disseminated gonococcal disease (DGD), also known as arthritis-dermatitis syndrome, due to the development of skin lesions, tenosynovitis, and arthritis. The most frequently affected population is young adults. We describe the case of an adolescent female who acutely developed skin lesions, arthritis, tenosynovitis, and constitutional symptoms.

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.

Frontal penetrating arrow injury: A case report.

Background: Penetrating arrow injuries of the head and neck are exceedingly rare in pediatric patients. This pathology has high morbidity and mortality because of the presence of vital organs, the airway, and large vessels. Therefore, the treatment and removal of an arrow is a challenge that requires multidisciplinary management.
