[Urinary tract infection caused by Enterobacteriaceae and its relationship with vesicoureteral reflux].

Background: The first urinary tract infection can be a marker of a urinary tract anomaly, mainly vesicoureteral reflux. The aim of this work was to determine the association between isolated enterobacteria with the presence and grade of vesicoureteral reflux in neonatal patients with their first urinary tract infection.

Methods: A retrospective, observational and analytic study of newborns, who were admitted to the Neonatal Department, University Pediatric Hospital "Juan Manuel Márquez," in Havana, Cuba, from 1992 to 2013 was conducted.

[Neonatal acute suppurative submandibular sialadenitis. Literature reports from 1950-2015].

Background: Submandibular salivary gland infections are uncommon. For this reason, neonatal acute suppurative submandibular sialadenitis non-coincident with parotitis is considered as a rare entity. The aim of this work was to verify if there have been changes in the clinical and microbiological aspects of this infection from its first descriptions.

[Prevalence and characteristics of the vesicoureteral reflux in infants who suffered neonatal urinary tract infection].

Introduction: The risk of developing renal scars is higher in the first years of life, mostly when the patient has vesicoureteral reflux, for that reason is necessary to identify this reflux as early as possible. Our aim was to determine the prevalence and characteristic of presentation of vesicoureteral reflux in infants who suffered neonatal urinary tract infection.

Method: Observational, prospective study, from 1992 to 2007, of a newborn cohort that suffered the first urinary tract infection acquired in the community with upper localization for clinical criteria, who had been carried out renal ultrasound and mictional urethrocystography.
