OBJETIVO: investigar a presença de queixa de vertigem em pacientes de meia idade com hipertensão arterial. MÉTODOS: estudo do tipo prospectivo, transversal. Composto por 154 indivíduos de ambos os gêneros com idade de 45 a 64 anos. A hipertensão foi verificada por meio de medição da pressão arterial e de questionário sistematizado sobre hipertensão e uso de medicamentos para pressão arterial. A queixa de vertigem foi verificada por meio de anamnese audiológica. RESULTADOS: pode-se verificar que existe associação significante entre hipertensão arterial e queixa de vertigem. CONCLUSÃO: os resultados da presente pesquisa, por meio da constatação da associação entre hipertensão arterial e queixa de vertigem, servirão de base a profissionais da área de saúde que estão envolvidos com sintomas provenientes da hipertensão arterial.

Aim: To identify likely association between blood hypertension and hearing loss. Design: A non-paired casecontrol study. Setting: Institutional work carried out at Universidade Norte do Paraná, in South Brazil. Material and Method: 154 cases and 154 controls, both genders, aged 45 to 64, included in the research after sample estimation. Methodology: Hypertension was verified through blood pressure readings and by a systematized questionnaire about hypertension and the use of medication for blood pressure. Hearing was assessed through tonal threshold audiometrics and audiologic anamneses. Non-conditional logistic regression was used in order to control likely confusion or modification of effect of other variables on interest associations. Results: There is a significant association between blood hypertension and hearing loss. Hearing loss in the population under study suggests that hypertension is an accelerating factor of degeneration of the hearing apparatus due to aging. Conclusions: The results in this research, through evidence of association between blood hypertension and hearing loss, can allow for an integrated work of cardiologists, nephrologists, otorhinolaryngologists, audiologists and other health professionals concerned with alterations caused by blood hypertension.

Objective: To determine the frequency of adrenal insufficiency in children diagnosed with sepsis that were staying in pediatric intensive care units and to establish the association between adrenal function and the use of vasoactive drugs, mechanical ventilation time and mortality.Methods: A cohort-designed study was conducted to assess the incidence of adrenal insufficiency in children aged 29 days to 12 years who were diagnosed with sepsis using the adrenocorticotropic hormone (ACTH) stimulation test.Results: Thirty-nine children were included in the study. The frequency of adrenal insufficiency was 30.7% (12 patients). Children with adrenal insufficiency had an increased need for vasoactive drugs as well as longer mechanical ventilation times; however, the differences were not statistically significant. A KaplanMeier curve indicated lower survival rates among the adrenal insufficiency children, but the differences were not statistically significant (p = 0.1263). No differences were identified between the adrenal sufficiency and adrenal insufficiency groups in regards to mechanical ventilation time, use of vasoactive drugs, infection type and chronic disease.Conclusion: This study determined the frequency of adrenal insufficiency in children with sepsis and its relationship to increased mortality within the first 28 postadmission days. No statistically significant association was found between adrenal insufficiency and mechanical ventilation time or the use of vasoactive drugs.Keywords: Sepsis; Adrenal insufficiency; Corticotropin-releasing hormone; Vasoactive drugs; Children This study was conducted at the Hospital Universitário Regional do Norte do Paraná, Universidade Estadual de Londrina -UEL -Londrina (PR), Brazil. Conflicts of interest:None.
