Evaluation of preoperative geriatric assessment of elderly patients with colorectal carcinoma. A retrospective study.

Aims: Elderly patients with colorectal carcinoma are screened with the Identification of Seniors at Risk (ISAR) questionnaire to identify frail patients. These patients are more at risk for mortality and morbidity and are referred to the geriatric specialist for assessment (Dutch acronym: DOG). The DOG assessment aims to preoperatively optimize the patient in order to improve postoperative outcomes.

Effect of nutrient supplementation on serum homocysteine, iron and proteins in psychogeriatric patients.

In a longitudinal follow-up study the effect of pharmaceutical supplementation of nutrients (folate, vitamin B12, B6, B1, C, iron and proteins) was established in 25 psychogeriatric patients (subject group). A reference group of 30 apparently healthy elderly subjects was used for comparison and statistical evaluation. At the time of hospitalization percentages concerning the incidence of decreased serum concentrations reflecting an inappropriate nutrient state in the subject group amounted to 28% for vitamin B12, 20% for folate, 36% for iron, 12% for transferrin and 56% for albumin concentrations.

[Decreased erythropoiesis and biochemical deviations in psychogeriatric patients].

Laboratory investigations were performed in group of 60 psychogeriatric patients on their admission into hospital, in order to elucidate the interdependence of erythropoiesis and the concentrations of albumin and several vitamins in blood or serum. The results of albumin concentration and ETK activity show that 47 out of 60 the patients (= 78%) are in a poor nutritional condition. In 13 of these 47 subjects (= 28%) deficiency with respect to vitamin B12 or folic acid is presumed from decreased serum concentrations.

Gadolinium-DTPA enhanced MR imaging of intravenous extension of adrenocortical carcinoma.

A case of magnetic resonance imaging of adrenocortical carcinoma extending into the inferior vena cava is presented. Magnetic resonance was able to outline the intraluminal extent of tumor thrombus accurately. Signal intensity ratios (mean 0.
