Our purpose was to determine the in-hospital incidence of delirium among elderly patients, its relation to previous cognitive impairment and the time between admission and its development. We performed an observational study of follow-up in the internal medicine area of a university hospital. We included consecutively and prospectively every patient 70 years or older upon admission. ⋯ During the first 4 days of hospitalization 58.3% of delirium cases occurred not modifying the duration of hospitalization (average: 10.22 days vs 14.38; p = NS). We conclude that the incidence of delirium is high among hospitalized elderly patients specially during the first days, and in those with previous cognitive impairment. We suggest that delirium could be an associated disorder in severe diseases among patients with previous cognitive damage.

Our objective was to determine delirium incidence and risk factors in a cohort of elderly inpatients. We randomly selected 149 patients, aged 65 years or older, from admission to general wards, without evidence of delirium. They were evaluated daily with the Confusion Assessment Method, an instrument validated for the diagnosis of delirium. ⋯ We conclude that delirium in our setting is very frequent and has negative effects on resource utilization and mortality in elderly inpatients. Its association with the severity of the disease seems interesting. Appropriate prospective identification of patients at risk for delirium may allow the implementation of preventive strategies in order to minimize the impact of this complication.

Hypersensitivity pneumonitis (HP) is the clinical manifestation of an pulmonary immunological reaction to inhaled antigens. The list of provocative antigens and specific illnesses grows permanently. A woman of 56 years consulted for dyspnea and cough of two months of evolution. ⋯ A lung biopsy confirmed the diagnosis of HP. She improved with systemic corticosteroids and the avoidance of antigen exposure. In the cultures of the material that recovers the salamis, Penicillium spp. was recovered and was interpreted as the probable etiological agent of this HP, which we have denominated "the salami worker's lung".

Antiphospholipid syndrome is characterized by recurrent fetal loss, arterial and venous thromboses, thrombocytopenia and circulating antiphospholipid antibodies. Few patients have a rapidly progressive, fatal outcome. ⋯ Although clinical and laboratory findings differed in both patients--small vessel thromboses and microangiopathic hemolytic anemia mimicking thrombotic thrombocytopenic purpura predominated in one of the patients while small and medium size vessel thromboses without hemolysis were present in the other case--autopsy revealed widespread visceral thromboses in both of them, features consistent with a diagnosis of catastrophic antiphospholipid syndrome. This syndrome has not been reported to occur in association with Pneumocistis carinii pneumonia as we describe in one of our patients.
