The aim of this paper is to study the prevalence of Zika Virus (ZIKV) and the index of its neurological complications. This is a quantitative, cross-sectional epidemiological study. Data were collected through the compulsory notification of suspected ZIKV and its neurological alterations cases. 113 suspected ZIKV cases were reported, most of them in the summer, with a higher prevalence of females and in the fourth decade of life. Among the neurological changes, 15 Guillain-Barré Syndrome cases were reported, with one registered death. As neurological manifestations, most of them started 30 days after a ZIKV infection. No case has been confirmed laboratory. It is necessary to combat the vector, mainly in the summer, to reduce ZIKV infection and its neurological complications, besides instruction to the health professionals about these complications and serological tests requests for an accurate diagnosis.
Headaches are particularly relevant as a complication of hemodialysis, given that this condition increases the discomfort felt by patients undergoing this therapy. The objective of the present study was to evaluate the prevalence of headache in patients undergoing hemodialysis sessions, particularly considering dialysis headaches due to caffeine-withdrawal. This was a crosssectional, observational, quantitative and qualitative study with questionnaires and interviews. The questionnaire addressed biopsychosocial aspects, clinical aspects and criteria for the classification of headaches according to the International Headache Society. A hundred and sixty patients with stage-V chronic kidney disease responded to the questionnaire during hemodialysis sessions. Headache prevalence was 90% and over the period studied 53.1% of patients presented the symptom. Among these patients with headaches, over half (55.3%) presented criteria for concomitant caffeine-withdrawal headaches and dialysis headaches. The beginning of headaches varied between one month and more than five years, with most occurring for more than five years. Frequency varied from sporadic crises to more than one crisis a day, though more than one crisis a day predominated. The interval between crises was of a few days, with mean duration of less than one hour, which ceased with the use of self-medicated analgesics, with no worsening factor. This condition is a challenge for neurologists and headache experts. More studies are needed to decrease this prevalence, to decrease the abusive use of analgesics and improve the quality of life of these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
