Introduction:The psychomotor development evaluation (DSM) is an essential component in health supervision mainly in children under 5 years. The objective of this study is to favor the investigation of retardation in psychomotor development and allow that it is possible to intervene early and in a timely manner. Patients and methods: A descriptive, prospective, cross-sectional, observational study was carried out in the outpatient clinic of the family medicine unit Number 66 of the Mexican Social Security Institute, Xalapa Veracruz. During a year in the right-wing population of children from 1 month to 59 months of age, patients with neurological disease were excluded, a sample of 388 children was obtained and evaluated with the Child Development Assessment (EDI) test in three ABC groups. Results in group A from 1 to 2 months and group B from 2 to 11 months of age, no delay in psychomotor development was found, in group C from 12 to 59 months 4 children had developmental delay being 1.3% of the population studied, presenting alterations in the fine motor area with 0.3%, the language area 1.5% and the social area 1.5% being this group the most representative. Conclusions: the EDI test was shown to be useful for the detection of psychomotor development delay in children under 5 years of age, mainly with a history of prematurity and low birth weight.

Objective: IE is a rare diagnosis in children, although its incidence is increasing, with figures of 0.34 to 0.64 cases per 100,000 inhabitants / year. The NVE has a bimodal distribution with peaks in childhood at 12 to 16 years of age. We present the case of a 14-yearold male with no history of congenital heart disease, respiratory infections, or catheter placement, a course with urinary tract infection treated with cephalosporin, and a month later he developed infectious endocarditis with a double complicated aortic valvular lesion that merited urgent surgical intervention. Conclusion:Infective endocarditis is rare in children. The presence of persistent fever, heart murmur without structural lesion and antecedent infection should be ruled out.
