RESUMEN
In order to compare the effects of leisure physical activity (LPA), aerobic training (AT) and aerobic plus resistance training (AT + RT) as part of a 6-month interdisciplinary therapy in body composition, insulin resistance and leptin concentrations in obese adolescents, 72 volunteers (n = 24 in each group) ages 15-19 years were evaluated. Delta (Δ) body mass (kg) and Δ BMI (kg/m(2)) was different between AT and LPA groups and in AT + RT group compared to both LPA and AT groups; Δ body fat mass (kg and %) was different only in AT + RT group compared to both LPA and AT; Δ body lean mass (%) was different only in AT + RT group; Δ body lean mass (kg) was negative only in AT and positive and different from AT in AT + RT group; ΔHOMA-IR did not differ among groups; Δ leptin (ng/ml) was negative and different from LPA for both AT and AT + RT groups. In conclusion, both AT and AT + RT promoted a reduction on leptin levels, however, the adolescents subjected to AT + RT presented better results in body composition than the AT group. These results highlight the importance of associating aerobic and resistance training with nutritional and psychological approaches in the treatment of obese adolescents.

OBJECTIVE: To present a review of the current diagnostic and therapeutic approach to the major conditions found in pediatric emergency department, which course with acute respiratory tract disfunction, stressing some clinical and epidemiological characteristics that are useful to the pediatrician in the differential diagnosis.METHODS: Outstanding articles related to the subject were selected after literature review of the last 20 years, using Md Consult, Medline and Lilacs databases.RESULTS: Many diseases can produce respiratory disfunction. Taking into account only those with acute symptoms, infectious and/or inflammatory causes predominate. History, examination findings and at least a chest X-ray are almost always sufficient for the diagnosis, but, sometimes other complimentary tests are necessary.CONCLUSIONS: If not properly treated, acute respiratory emergencies can result in significant morbidity and mortality. Any pediatrician taking part in an emergency team has to obtain respiratory management skills and knowledge concerning distinctive aspects and severity estimation of the several respiratory diseases.
