Background: Previous studies indicate that compared with physical examination, Doppler echocardiography identifies a larger number of cases of rheumatic heart disease in apparently healthy individuals., Objectives: To determine the prevalence of rheumatic heart disease among students in a public school of Belo Horizonte by clinical evaluation and Doppler echocardiography., Methods: This was a cross-sectional study conducted with 267 randomly selected school students aged between 6 and 16 years. students underwent anamnesis and physical examination with the purpose of establishing criteria for the diagnosis of rheumatic fever. They were all subjected to Doppler echocardiography using a portable machine. Those who exhibited nonphysiological mitral regurgitation (MR) and/or aortic regurgitation (AR) were referred to the Doppler echocardiography laboratory of the Hospital das Clínicas of the Universidade Federal of Minas Gerais (HC-UFMG) to undergo a second Doppler echocardiography examination. According to the findings, the cases of rheumatic heart disease were classified as definitive, probable, or possible., Results: Of the 267 students, 1 (0.37%) had a clinical history compatible with the diagnosis of acute rheumatic fever (ARF) and portable Doppler echocardiography indicated nonphysiological MR and/or AR in 25 (9.4%). Of these, 16 (6%) underwent Doppler echocardiography at HC-UFMG. The results showed definitive rheumatic heart disease in 1 student, probable rheumatic heart disease in 3 students, and possible rheumatic heart disease in 1 student., Conclusion: In the population under study, the prevalence of cases compatible with rheumatic involvement was 5 times higher on Doppler echocardiography (18.7/1000; 95% CI 6.9/1000-41.0/1000) than on clinical evaluation (3.7/1000-95% CI).

Objective: Compare clinical and Doppler echocardiographic evaluations in assessing valvular diseases in children and adolescents with rheumatic fever, as well as assess the progression of the disease in light of these assessments., Methods: This is a longitudinal study of 258 children and adolescents diagnosed with rheumatic fever according to Jones criteria. The follow-up period ranged from 2-15 years. The presence and quantification of valve diseases were determined by means of clinical and Doppler echocardiographic evaluations performed during the acute and chronic phases. The Kappa statistics method was used to estimate the degree of agreement between clinical and Doppler echocardiographic evaluations. Comparisons between clinical and Doppler echocardiographic findings on the progress of carditis and valvulitis, respectively, were made using chi-square test or Fishers exact test, p< 0.05., Results: Of the 109 patients who underwent Doppler echocardiographic evaluation during the acute phase, 31 did not present clinical evidence of carditis, but the Doppler echocardiograms of 17 (54.8%) of them showed valve lesions (subclinical valvulitis). During the chronic phase, 153 of the 258 patients had normal cardiovascular examination results; however, Doppler echocardiograms showed that 81 of them (52.9%) had valve lesions (subclinical chronic valvular diseases). Involution of the valvular lesions, as shown by Doppler echocardiographic evaluations, was less frequent and occurred in 10 (25.0%) patients with mild valvulitis, in only one (2.5%) patient with moderate valvulitis, and in none of the patients with severe valvulitis., Conclusion: The identification of rheumatic fever valve lesions can be enhanced when clinical evaluations are supplemented by Doppler echocardiographic examinations; also, clinical examinations are not as suitable to detect valvular lesion regression as the echocardiography. The diagnosis of subclinical valvulitis and valvulopathy influences the secondary prophylaxis of rheumatic fever and endocarditis.

The changes that occurred on the childhood's view and on the way to handle it are described here, including that refers to odontology-odontopediatrics; the influence carried out by psychology is also discussed in this paper, which sets the proposal of an assimilation of psychological knowledge by odontopediatrics guided by the aim to promote child's development.
