INTRODUCTION: Fever appears in a fourth of @entity64 , approximately. Its origins, (the most of them are infectious) are unknown in a minority of the cases. Some hypotheses indicate that central mechanisms like @entity1640 or segregation of endogenous pyrogens may be implicated. OBJECTIVE: To evaluate the frequency of central @entity221 during @entity64 and to notice if there are clinical differences between infectious and central origins of the @entity221 . @entity1 AND METHODS: 103 @entity1 were evaluated prospectively, if someone had @entity221 , an investigation about an infectious origin was made. We divided the @entity221 @entity1 into two groups: " @entity221 without @entity281 documented" and we analyzed the clinical differences between them. RESULTS: 23% of the @entity1 had @entity221 , 33% without @entity281 documented. This last group had earlier fevers. They had more clinical severity and more mortality. The @entity221 was higher and it didn't response to the antipyretic treatment also. The others parameters didn't show any difference between the two groups. CONCLUSION: The @entity1 with @entity221 without @entity281 documented ( probably @entity221 of central origin)had a defined model with its own characteristics, in a different way from infectious @entity221 .
