Ethnography and family medicine: issues and overview.

Ethnography is a qualitative research model generally associated with anthropology. Ethnographic methods include inductively oriented strategies such as participant observation, structured interviews, and open-ended interviews. Issues in family medicine such as patient compliance, doctor-patient relationships, and patients' subjective experience of illness may be optimally studied with ethnography. Because it is inductive, ethnography is cognitively similar to clinical reasoning. Making use of ethnography provides family physicians with a greater array of research methods compatible with clinical practice.

Distal Chevron metatarsal osteotomy for bunionette.

Nineteen distal chevron metatarsal osteotomy operations were performed in 13 patients with painful bunionette. The average duration of follow-up was 7.1 years. Mean forefoot score improved from 35.8 points to 73.9 points out of a possible 75 points. Intermetatarsal 4-5 angle, metatarsophalangeal 5 angle, and forefoot width improved significantly. Overall results were considered good in 17 feet and fair in 2; there were no failures. Complications were transfer metatarsalgia (1 foot) and wound infection (1 foot). Distal chevron fifth metatarsal osteotomy is effective treatment for symptomatic bunionette.

Mechanical cornpicker hand injuries.

The mechanical cornpicker causes tearing anse injuries from 1962 to 1975 were studied with regard to mechanism and extent ohe time of injury in 36% of hands, and in 73% of the remainder following treatmophylaxis, and antibiotics, and 73% hands required some form of delayed surgical treatment. Antibiotics did not appear to be helpful. Eighty-nine ps the most common cause given for farmers for their injuries. Excluding four pr permanently disabled patients, the average length of disability was 135 days. Eighty-nine per cent of patients experienced some permanent impairment of hand function. The mechanical cornpicker is described, and the importance of its proper use and physician's emphasis on accident prevention as well as treatment are stressed.

Evaluation of the Gambro Lundia Major 1.36 m2 disposable parallel plate dialyzer.

The Gambro Lundia Major 1.36 m2 dialyzer was assessed in vivo in ten hemodialysis patients. Urea and creatinine clearances (measured as whole blood values at 60 minutes with a blood flow rate of 200 ml/minute) were 166 +/- 8 m/minute (mean +/- standard error of the mean, n = 9) and 115 +/- 4 ml/minute (n = 11). The creatinine clearance is 15% lower than in vitro data. There was a marked decrease in urea and creatinine clearance with third use of the dialyzer. The ultrafiltration rate was 490 ml/hour/100 mmHg. The priming volume was 125 ml (at a transmembrane pressure of 100 mmHg) and residual blood volume in the dialyzer was 0.57 +/- 0.11 ml (n = 5). The handling, storage and ease of disposal of the dialyzer is better than previous models and its performance characteristics are clinically acceptable.

Total joint arthroplasty. The hip.

Total hip arthroplasty, one of the most successful orthopedic procedures of this century, can provide relief of pain and improved function in a wide variety of hip conditions. Long-term follow-up has shown, however, that problems can occur, especially with the femoral prosthesis. As a result of this, surface-replacement total hip arthroplasty was developed, and at present it appears to be a very useful procedure for younger patients with concentric hip disease. Both procedures are discussed along with restrictions and complications inherent in their use.

Role of surgery in the management of pulmonary sporotrichosis.

Management of four patients with sporotrichosis is summarized; one was treated medically and three were treated surgically. Thirty-seven cases from the literature are reviewed. The role of surgery in the management of pulmonary sporotrichosis is outlined as follows: (1) diagnosis of pulmonary infiltrates and/or pulmonary cavities of undetermined origin, (2) surgical intervention in patients with persistent infiltrates with cavitary lesions resulting from sporotrichosis, following failed medical treatment, and (3) resection of associated pulmonary cavitary lesions in patients in spite of adequte medical control of sporotrichosis. Surgical principles that must be observed in the management of pulmonary sporotrichosis follows:(1) Resection is the procedure of choice. The magnitude ranges from segmental resection to pneumonectomy. Clean resection is necessary. (2) Antifungal drug therapy--preferably with amphotericin B--is advisable preoperatively and postoperatively, since the major cause of late death is progression of the disease when clean resection has not been feasible. (3) Resection combined with drug therapy can be curative without increased risk in physiologically operable and anatomically resectable disease. (4) Thoracoplasty can be a lifesaving procedure for bilateral cavitary lesions with severe hemoptysis in patients with impaired pulmonary functions.

Recovery from unilateral visuo-spatial neglect?

Patients who had demonstrated unilateral visuo-spatial neglect on a simple drawing and copying task three to four weeks after a right hemisphere stroke were reassessed five months later. Although the incidence of neglect as defined had dropped markedly in that period, they remained impaired on tests of spatial analysis and visual perception relative to a group of right hemisphere patients without neglect. The measurement of neglect is discussed in the light of both these results and the stability of the neglect group's abnormal position preference on one of the tests administered.
