[Normal values of the hemogram and other hematological variables in subjects over 60 years old].

We studied 36 men and 94 women aged 60 to 85 years, without nutritional deficiencies or illness that could interfere with hematopoiesis, to characterize the normal limits of red and white blood cell counts. Lower limit of hemoglobin normal values were 132 g/l for men and 125 g/l for women. The corresponding figures for MCV were 85 fl and 83 fl for men and women respectively. Lower and upper normal limits for leukocyte count in both sexes were 3.66 and 9.36 x 10(9)/l. Hypersegmented neutrophils existed in 7% of men and 14% of women in spite that folate and vitamin B12 deficiencies were excluded. We concluded that blood cell counts of elderly people have mild deviations of normal values for young adults. Aged humans have a low white cell and bands counts, and elderly women have a higher hemoglobin concentration.

Age Distribution

[Geriatric evaluation of elderly patients at a university hospital].

The aim of this work was to evaluate general aspects, medical diagnoses, degree of disability, mental status and social support of hospitalized elders using a Geriatric Assessment Scale, devised at the Catholic University. Ninety eight hospitalized subjects (58 female, aged 60 to 74 years old) were surveyed before discharge. Results showed that 34% had serious handicaps in their daily living and required third party help, 14% had a moderate cognitive impairment and that 12% lacked social or family support. We conclude that the scale is useful, easy to use and allows to obtain a thorough diagnosis of hospitalized elders.

Aged

[Spontaneous coronary artery dissection in a young woman with acute myocardial infarction. Clinical case].

Spontaneous coronary artery dissection in the absence of atherosclerosis, is a rare cause of acute myocardial infarction. We report a 37 years old woman with an inferior wall acute myocardial infarction secondary to an spontaneous dissection of the right coronary artery. The patient's evolution was uneventful and a new angiography performed six months later showed that the dissection persisted. The possible etiologies and treatment are discussed.

Adult

[Mushroom poisoning in the IX region. Role of Amanita gemmata].

We report four episodes of mushroom poisoning that occurred between 1986 and 1990 in the province of Malleco. Twenty five of 36 individuals who ingested the mushroom became ill; they had an acute gastroenteritis that was followed in 7 by an acute hepatitis and in one by a massive upper gastrointestinal bleeding. Three subjects with fulminant hepatic failure and the subject with the massive bleeding died. Amanita gemmate (strain described as toxic in Chile since 1967) was found in two episodes and Amanita sp in one. The clinical picture is similar to that described for Amanita phaloides. The treatment is symptomatic but penicillin and silymarin may have an antitoxic action. The importance of warning the population about the existence of toxic mushrooms in Chile is emphasized.
