Subdiagnóstico de delirium en adultos mayores hospitalizados

Aim: To evaluate the prevalence of delirium at hospital admission in medically ill elderly patients and the attending physician's diagnosis and treatment of delirium. Patients and methods: In a prospective and descriptive study, consecutive patients aged 65 years or more, admitted to an internal medicine ward were evaluated by independent physicians, during the first 48 h of admission, to asses the presence of delirium. Diagnosis of delirium was based on the Confusion Assessment Method. Medical and nurse records were reviewed. Family was interviewed when necessary. Results: One hundred eight patients (52% women, age range 65-94 years) with an APACHE II score of 11.6±5, were evaluated. Fifty seven patients (53%) had delirium (32% hyperactive, 72% hypoactive and 5% mixed). Delirium prevalence was significantly higher in older patients (66% among those aged 75 years or older versus 30% in younger, p <0.05) and among patients with more severe conditions (88% among those with an APACHE score over 16 versus 47% below that value, p <0.05). Medical records of patients with delirium showed that this diagnosis was present only in 32% and cognitive deficit was described in 73%. Ten percent of patients with delirium received sedative medication and 38% were physically restricted. There were no environmental interventions to prevent or control delirium. Conclusions: Delirium in elderly inpatients at this unit is an extraordinarily prevalent problem, seriously under diagnosed (68%) and under treated. This study should alerts our medical community to improve the diagnosis and management of delirium in elderly inpatients (

Anophelines in the state of Acre, Brazil, infected with Plasmodium falciparum, P. vivax, the variant P. vivax VK247 and P. malariae

Of the 3056 specimens collected, 2610 were Anopheles oswaldoi, 362 A. deaneorum, 60 A. triannulatus and 24 were A. darlingi. The infection rates of A. oswaldoi were 3.41% for P. falciparum, 2.26% for P. vivax, 1.22 for P. vivax VK247, and 0.42% for P. malariae. For A. deaneorum, the infection rates were 2.76% for P. falciparum, 0.55% for P. vivax, and 0.82% for P. vivax VK247. All samples of the other 2 species collected (A. triannulatus and A. darlingi) were negative in the ELBA. There were certain differences in the anopheline distribution and infection rates between these localities, and in one only A. oswaldoi was found to be infected. These results strongly point to A. oswaldoi as the main malaria vector in the region. No difference was found between the potential vectors of P. vivax and P. vivax VK247. The significance of these findings for malaria control is discussed.
