Accident consultations in one month in a semirural town.

General practice statistics for the month of July 1986 were analysed from a semirural town. There were 498 accident consultations and Maoris tended to be underrepresented. Thirty six percent of accidents were at work, 30% in the home and 12.6% in sports. Twenty three percent of the accidents involved no time off work and 32% had up to a week off. Thirty percent made a claim for earnings related compensation to ACC. Eight patients had prolonged periods off work.

The role of apheresis in the support of life-threatening ITP relapse.

A 14-year-old girl with chronic idiopathic thrombocytopenic purpura (ITP) presented in relapse with a platelet count of 1,000/microL and a high-level serum antiplatelet IgG antibody. She previously had been unresponsive to courses of therapy with steroids, vincristine, and splenectomy. When treatment with danazol and purified immunoglobulins was unsuccessful in controlling her rapidly progressive course, an 8-day plasma exchange procedure was initiated in combination with platelet transfusion therapy and immunosuppression with cyclophosphamide and vincristine. Within 2 days, her clinical state improved markedly, correlating with a drop in her serum antiplatelet antibody level. She continued to improve and was discharged on a regimen of cyclophosphamide and danazol. Her antiplatelet antibody level had fallen to within the normal range, despite a typical platelet count of 5,000/microL during the 8-day period. Two weeks later her platelet count rose to 65,000/microL. This case suggests that a course of therapeutic plasma exchange may have a temporizing role in the acute management of life-threatening chronic ITP relapse, generating time for the more definitive therapy of immunosuppression to take effect.

An estimation of mineral losses through arm sweat of preadolescent children.

Balance studies were conducted to determine the effects of three levels of nitrogen intake on the loss of nitrogen through sweat in preadolescent boys and girls. During the studies, the losses of calcium, iron, magnesium, manganese, potassium, sodium, and zinc were determined in the arm sweat of the subjects. Sweat from the forearm was collected in a polyethylene bag for 1 hr on three different occasions. Using the concentrations of nitrogen in the arm bag and in the whole body collection and the concentration of minerals in the arm bag, the total body loss of minerals were estimated. Losses of minerals through sweat, expressed as a percentage of intake, ranged from 0.12 to 1.10%. Under conditions of these studies, sweat losses of the essential minerals were not a significant factor in estimating total losses.
