Increased Vulnerability to Pregnancy and Sexual Violence in Adolescents with Precocious Menstruation.

This cross-sectional, observational, and descriptive study was conducted to evaluate the association between age at menarche in the adolescent population and the age at sexual initiation, age at first pregnancy, and experience of sexual violence in the adolescent population visiting a primary health unit in Brazil. We recruited 201 female adolescents who visited the gynecology outpatient clinic of a Basic Health Unit in the Federal District of Brazil. These adolescents answered a questionnaire with regard to sexual and reproductive health during doctor's appointments.

The formation of citizens: the pediatrician's role.

Objective: This review article aims to define the fundamental role of the pediatrician in the formation of citizens in the 21st century.

Source Of Data: Significant bibliographical contributions produced by neuroscience, ecology, and epigenetics in the early childhood scenario.

Synthesis Of Data: Many diseases that impair the lives of adults result from severe and often uncontrollable disorders that occur in early childhood, an irreplaceable period for the safe construction of the human brain, personality, and intelligence.

Sleep deprivation, pain and prematurity: a review study.

The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted.

Autism spectrum disorder and celiac disease: no evidence for a link.

Objective: To evaluate the possible association between celiac disease (CD) and/or gluten sensitivity (GS) and autism spectrum disorder (ASD).

Methods: Occurrences of CD were determined in a group of children and adolescents affected by ASD and, conversely, occurrences of ASD were assessed in a group of biopsy-proven celiac patients. To detect the possible existence of GS, the levels of antigliadin antibodies in ASD patients were assessed and compared with the levels in a group of non-celiac children.

Emerging fluoroquinolone-non-susceptible group A streptococci in two different paediatric populations.

Clonal emergence of group A streptococci (GAS) with reduced susceptibility to fluoroquinolones (FQs) has been increasingly reported. Non-susceptibility is associated with various point mutations in the target-encoding genes and has only been described in a few emm types. We used a well-characterised GAS clinical paediatric collection from Brussels (Belgium) and Brasília (Brazil) to analyse the molecular basis of FQ non-susceptibility.

[Frequency of seropositivity to Toxocara canis in children of different socioeconomic strata].

Frequency of seropositivity for Toxocara in children from different socioeconomic strata in the city of Brasilia (Brazil) was measured. Six hundred and two children of both sexes, aged one to 12 years were distributed in two socioeconomically distinct groups. The samples of sera of the first group were obtained from blood drawn for routine tests in the laboratory of a public hospital attending children from low-income families.
