Atypical fibroxanthomas of the skin: multiple primaries

An 83-year-old man experienced, within a four-year span, two separate atypical fibroxanthomas occurring on the right ear and right forehead without any satellite lesions or obvious lymph node metastases. Such an occurrence has not been reported before.

An audio urine-glucose analyzer for blind diabetics

At the instigation of one of the authors (J.M.)--a young man whose blindness is due to diabetic retinopathy--a urine-glucose analyzer was designed and constructed. Its purpose and function enable him to test his urine himself (free of dependence on thers for this service) and, thereby, he can then determine and administer his doses of insulin. He and other young blind diabetics may value the degree of freedom from dependence on others than the analyzer provides and feel it helps them to be able to work and care for themselves. A description of the instrument instructions for its use, and a summary of about 20 months' experience with it are submitted.

Epidemiology of single-unit transfusion. A one-year experience in a community hospital

The transfusion practices of an 850-bed community hospital are reviewed from Jan 1, 1962, through Jan 1, 1963. Twenty-nine percent (855 of 2,921) transfused patients received a single unit of whole blood or packed red blood cells. Eighty-two percent of single-unit transfusions were given to women, and 93% were related to surgical or obstetric situations. In patients undergoing common operative procedures, 62% had normal vital signs and hematocrit readings before transfusion. Sixty-seven percent of all patients had normal hematocrit readings prior to transfusion. One third of the single-unit transfusions were considered justified, and two thirds were regarded as questionable or unnecessary.
