Lysozyme content of tears in patients with Sjögren's syndrome and rheumatoid arthritis.

In 37 patients and 143 control patients we estimated tear fluid lysozyme content by the Micrococcus lysodeikticus agar diffusion assay. We found no correlation between the titer of lysozyme in tear fluid and the rate of tear flow. Decrease in lysozyme production was found to be a sensitive indicator of the involvement of the lacrimal system in Sjögren's syndrome.

Tocopherol in Osteoarthritis: a controlled pilot study.

Thirty-two patients entered a simple-blind, cross-over study on the action of tocopherol in osteoarthritis; only 3 did not complete the course. Each patient was randomly assigned either to the tocopherol group (600 mg/day for 10 days) or to the placebo group. After 10 days the groups were transposed. The analgesic and other possible effects of tocopherol vs. placebo were assessed by the patients' daily records, by the physician's personal examination and interview, and by observations on the use of an additionally permitted analgesic (pro re nata). In 52 percent of the 29 patients who completed the study of good tocopherol analgesic effect was noted, but only 4 percent of those receiving placebo reported a similar effect. The difference was statistically significant. Further large-scale assessement of the influence of tocopherol in osteoarthritis would seem to be justified.

Potassium, glucose and insulin administration in acute myocardial infarction: a five-year study.

Two hundred and twelve patients with acute myocardial infarction were treated for 14 days with daily doses of potassium (3 gm orally), glucose (280 gm orally) and regular insulin (16 units subcutaneously), all given in 4 fractional doses. The incidences of arrhythmias, heart failure and systolic blood pressure below 70 mm Hg, as well as the mortality rate, were compared with those for another group of 600 myocardial infarction patients who were not given this treatment. Though there was some reduction in the incidence of cardiac arrhythmias, it was not statistically significant. However, there was a strikingly significant decrease in the incidences of heart failure and blood pressure below 70 mm, as well as in the early mortality rate. Our findings should encourage the continued use of potassium, glucose and insulin therapy in acute myocardial infarction.

Studies of blood ascorbic acid levels in acute myocardial infarction.

Fasting serum samples from 53 patients with an acute myocardial infarction were investigated for their vitamin C content during the first week of their illness. The vitamin C levels found were generally within the accepted normal limits. However, there were highly significant lower levels on the second to the fifth post-infarction days, as compared with those found on days six to eight.

Patent ductus arteriosus in old age.

An unusual case of patient ductus arteriosus (PDA) in a 78-year-old man is presented. The patient was known to have PDA since the age of 30, but it had remained well compensated until shortly before death. He had undergone some difficult operations successfully, and had no specific pulmonary complaints. Death at age 78 was caused by arteriosclerotic heart disease following myocardial infarction. Autopsy revealed a smooth patent ductus arteriosus with no perforation. The survival of a PDA patient to such advanced age is a comparatively rare occurrence.

Functional and ultrastructural studies of Sezary cells.

A patient having clinical findings and typical ultrastructure of the peripheral white blood cells compatible with the diagnosis of Sézary syndrome is described. Studies of the synthesizing capacity of the Sézary cells showed a statistically significant increase in their capacity for protein and RNA synthesis, but no difference with regard to DNA synthesis as compared to normal lymphocytes.
