ABSTRACT
This study sought to verify the records on file and the number of cases of attempted suicide among children and adolescents who were attended by Emergency Care health professionals in the municipality of Matozinhos, Minas Gerais, Brazil. Documentary and descriptive research was conducted, the data for which was collected by means of an investigation of Outpatient Records from 2008 to 2010. Of the 73,000 files evaluated, those dealing with cases of attempted suicide among children and adolescents between the age of 3 and 18 years were selected. It was revealed that the health professionals, particularly physicians and nurses, fail to register the cases appropriately, invalidating information about the problem and potential prevention measures. The conclusion reached was that underreporting and the discrepancy of the diagnoses which were not duly referred to the competent agencies require rethinking and reviewing medical practices, and taking a systematic and careful look to address the individual as a complex whole.
Neste estudo procurou-se verificar o registro e o número de casos de tentativa de suicídio entre crianças e adolescentes do município de Matozinhos, Minas Gerais, Brasil, que foram atendidos pelos profissionais de saúde do Pronto-Atendimento. Trata-se de uma pesquisa documental e descritiva, cuja coleta dos dados ocorreu por meio de investigação nas Fichas Ambulatoriais, no período de 2008 a 2010. Das 73.000 fichas levantadas, selecionaram-se aquelas que tratavam de casos de tentativa de suicídio entre crianças e adolescentes do município, com idades entre três e 18 anos. Percebeu-se que os profissionais de saúde, mais especificamente os médicos e enfermeiros, não registram os casos de forma adequada, inviabilizando a informação sobre o problema e as medidas de prevenção. Concluiu-se que a subnotificação, a discrepância dos diagnósticos e o não encaminhamento aos órgãos competentes exigem repensar e rever a prática médica e dirigir um olhar sistematizado e cuidadoso para perceber o sujeito como um todo complexo.

The effect of psychosine on the rate of respiration at different segments of the electron transport chain, respiratory control ratio and the efficiency of phosphorylation was studied. The transfer of electrons through site I, site II and site III was studied independently. The transfer through site I and site III was inhibited by psychosine, whereas the transfer through site II was not inhibited. Cardiolipin, which is essential for the electron transfer through site I and III, was implicated to be responsible for the inhibition of electron transfer by psychosine. Electron carriers of site II are not sensitive to cardiolipin, so psychosine could not inhibit the electron transfer through this site. The ADP/O ratio and respiratory control ratio were inhibited by psychosine showing that it has an uncoupler like effect. Mitochondria isolated from rat liver, kidney and brain behaved essentially the same way in their response to psychosine. Cytochrome c oxidase was significantly inhibited by psychosine and the degree of inhibition was almost same in mitochondria and sub mitochondrial particles. The preence of outer membrane in mitochondria did not make any difference with respect to the action of psychosine on electron transport chain. Psychosine interacts at site I and site III and a change in the lipid environment of the membrane is responsible for the mitochondrial dysfunctions induced by psychosine. This represents a possible mechanism for the destruction of cells in Gaucher's and Krabbe's disease.
