摘要:

Sixteen patients with classical rheumatoid arthritis which had been present for longer than two years, representing anatomic stages II-IV, were treated with azathioprine in doses of 50 to 175 mg/day. They were followed up for up to six years. Using the criterion of ability to work, 93% of the patients improved markedly during the time observed. Complement levels were low before treatment and tended to stabilize within the normal range as the disease became less active. Erythrocyte sedimentation rate (ESR) fell during therapy but changes in ESR did not correlate well with the patients' clinical states. Titers of rheumatoid agglutinins showed little change after as long as six years of therapy. When all patients were stable a double-blind cross-over study, using a placebo tablet, was instituted. Fifteen of 16 patients had a marked exacerbation of disease activity after receiving placebo for three to eight weeks. When azathioprine was reinstituted, gradual improvement again occurred so that all patients were back to their asymptomatic or mildly symptomatic state within seven months.

摘要:

The results of 53 femoral to tibial artery bypass grafts have been reviewed. All were carried out in an attempt to salvage severely ischemic extremities which resulted from arteriosclerotic occlusive disease involving the femoral, popliteal, and tibial arterial systems as demonstrated by arteriography. Most grafts were done with autogenous vein; however, composite grafts comprised of a Dacron prosthesis and an autogenous vein and homologous veins were used in several patients. The initial salvage rate in these pregangrenous extremities was 74%. Fifty-two percent of the grafts remain patent at this writing, a period of 56 months in some instances. This study indicates that most patients with a severely ischemic extremity are candidates for revascularization and should have angiographic studies before amputation is considered.

摘要:

Specialized medical facilities tend to be concentrated in medical centers in metropolitan areas, which results in unavailability of adequate medical care to large portions of our population. One solution is a mobile unit, staffed by personnel representing several different disciplines (physicians, nurses, social workers, nutritionists, etc) and extending a health ministry beyond the confines of a medical center to medically deprived areas. The unit also has educational benefits as the medical and nursing students gain valuable experience by evaluating the patients and relating them to the environment in which they live. The mobile clinic allows for a workable situation in a congenial atmosphere without compromising the quality of health care.

摘要:

The lungs of 100 consecutive patients at autopsy and of 24 patients with various pulmonary neoplasms were analyzed for the presence of ferruginous (asbestos) bodies. The population comprised both rural dwellers and urban dwellers, in contrast to previous similar studies involving only urban dwellers. More than 90% of both population groups had ferruginous bodies in their lungs. There was no apparent difference in the incidence or quantity of ferruginous bodies between the group with pulmonary neoplasms and the randomly selected group. These findings raise the possibility of more widespread asbestos dust contamination of environmental air than has been previously thought and indicate that rural as well as urban populations are exposed. The failure to demonstrate more ferruginous bodies in the lungs of patients with pulmonary neoplasms is in accordance with the view that asbestos acts as a cocarcinogen in this regard.

摘要:

Everyone is conscious of the prime role of the ovaries in making a female a “female.” However, too little attention has been directed toward the systemic mechanism of estrogens that protects against coronary artery disease and osteoporosis. Exogenous estrogen appears to be almost as effective as the ovaries are in protecting a female from these diseases. The incidence of neoplasia in preserved ovaries after previous pelvic surgery is low. Emphasis has been placed on ovarian conservatism in the young female because a clearer benefit can be demonstrated in them than in postmenopausal females.

摘要:

Two cases of thymoma, one epithelial and one seminoma type are presented. In both instances, the thymoma infiltrated and later perforated the gastrointestinal tract by direct extension. One is the 30th reported case of thymoma with extrathoracic metastasis; this patient had metastasis to the bone marrow and kidney. Neither patient had myasthenia gravis associated with the thymic tumor.

摘要:

A survey of smoking habits of medical students was done using basic medical science graduate students at the same institution as a comparison group. Smoking status was not significantly related to sex, race, or academic classification. Knowledge of adverse health consequences of smoking was related to time spent in medical school and to whether or not the respondent smoked (ie, probable denial of knowledge of the adverse consequences among smokers). The respondent's smoking status was significantly related to familial and peer group smoking status and to peer group attitude. The most common reason given by quitters was “the media influence.” The nonsmoker most frequently never began the habit because of fear of health consequences. Because of the finding that a small percentage of medical students still are net convinced of the dangers of smoking, it was suggested that increased educational emphasis on these dangers be included in the medical curriculum.

摘要:

A case report of a patient with acute pericardial tamponade is presented. The etiology, pathophysidlogy, and management of cardiac tamponade is discussed. Preoperative management includes volume expansion, administration of catecholamines, and pericardiocentesis. Intraoperatively, monitoring should include continuous measurement of arterial and central venous pressures. Ketamine has been found to be very useful in these patients.
