Sarcoidosis severity and socioeconomic status.

Several chronic diseases are more severe in persons who are Black, of low socioeconomic status (SES), and underinsured. The authors ask if this is true for sarcoidosis. Associations among sarcoidosis disease severity, SES, insurance coverage, and functional limitations were analysed. Back and White sarcoidosis patients (n=110) of a municipal and university hospital sarcoidosis registry were interviewed by telephone. Data on disease severity were abstracted from patient charts. Most patients reported good or excellent health by demographic characteristics. Low SES and no or public insurance were associated with worse health status and more severe dyspnoea. More advanced radiographic stage was associated with lower income, and forced vital capacity impairment with less education. Physical and social activity limitations due to physical and emotional disability were related to no or public insurance and lower income, but not education. Sarcoidosis severity is associated with socioeconomic status and insurance indicators; no or public insurance and low income are associated with functional limitations. Sarcoidosis-associated limitations are substantial, emphasizing the social significance of sarcoidosis. Lack of private insurance may inhibit the use of medical care, contributing to disease severity and impairment.

Pulmonary sarcoidosis: comparison of patients at a university and a municipal hospital.

Charts and radiographs of sarcoidosis patients seen at a private university hospital and at a municipal hospital were reviewed to determine whether there was a difference in the severity of disease retrospectively. A standardized abstract form was used to identify and abstract information on new and continuing sarcoidosis patients seen at either Georgetown University Medical Center (GUMC) or District of Columbia General Hospital (DCGH) during a 2-year period. Because there were too few white sarcoidosis patients for comparison, analysis was done for African-American patients only. African-American patients at GUMC were slightly older, with a higher percentage of women. For GUMC patients, 76% had private insurance and 21% had public insurance, and for DCGH patients, one-half had public insurance and 29% had no insurance. Significantly fewer GUMC patients (7% versus 36%) reported moderate to severe dyspnea. Chest radiographs showed a larger percentage of patients with stage 1 disease at GUMC and more patients with stage 4 disease at DCGH. Spirometry showed more impairment of forced expired volume in one second (FEV1) in GUMC patients, but diffusing capacity of the lung for carbon monoxide (DLCO) values were significantly lower among DCGH patients. Less than 8% of GUMC patients showed disease progression compared with almost one-third of DCGH patients. These results demonstrate that substantially less severe pulmonary sarcoidosis was seen in African-American patients treated at a private, nonprofit university hospital compared with a municipal hospital. Factors that determine the use of municipal hospitals, such as limited financial access to care and sources of patients, may have played a major role in the differences seen.

Familial sensory autonomic neuropathy with arthropathy in Navajo children.

Eight Navajo children had a neuropathy characterized by Charcot's joints and unrecognized fractures. Their reflexes were intact and they had normal strength. The sensory examinations in the group were variable. Many had no discernible sensory deficit. Others had subtle deficiency in deep pain sensation, temperature discrimination, and corneal sensitivity. Electromyography and nerve conduction velocities were normal in the seven studied; however, sural nerve biopsy revealed a marked reduction in small myelinated and unmyelinated nerve fibers. This sensory neuropathy, which we call "Navajo familial neurogenic arthropathy," differs from the acromutilating sensory neuropathy previously described by Appenzeller et al in Navajo children. It also differs clinically from a number of previously reported cases of hereditary sensory autonomic neuropathies in non-Navajos. The disorder in these eight children emphasizes the usefulness of pathologic investigation of the sural nerve in patients with Charcot's joints with minimal or no other neuropathic signs.

Elderly patients' satisfaction with care under HMO versus private systems.

In one community, 100 elderly persons (25 HMO and 75 private patients) completed a 20-item scale that measured satisfaction with medical care. Data on demographics, health care utilization, and self-assessed health status also were collected to determine whether these variables would relate to HMO membership. Satisfaction scores were compared between HMO and private care groups by multivariate analysis of variance. Satisfaction with the doctor-patient relationship and convenience of care was higher in the private care group, whereas satisfaction with cost was higher in the HMO group. Interestingly, the HMO group evaluated private care and HMO care similarly. The private group rated HMO care less favorably. Additional comments reveal specific areas of satisfaction/dissatisfaction.

Sterilization among american Indian and chicano mothers.

In a large study concerning family size and birth control among women from five cultures in the Miami, Florida, area, it was noted that 60 percent of the Miccosukee and Seminole Indians having five or more children were surgically sterile. Compared with the incidence for whites (30%) and a similar socio-economic group of Chicanos (20%), the incidence among Indian women seemed highly inflated. To examine why this should be so and whether or not there were negative effects of such sterilization, analyses examined both pre- and post-operative differences between the Indians and a comparison group of Chicanos. Though there were significant cultural differences found for the women, these differences did not interact significantly in predicting sterilization. However, sterilized women reported significantly more pregnancy complications. Factors which may have contributed to the greater incidence of tubal ligation among Indian women are explored.

Satisfaction with ambulatory care and compliance in older patients.

Predictors of satisfaction with ambulatory care and compliance in 267 older and 581 younger patients were determined. Each patient rated a 45-item satisfaction-with-care-scale. Race, SES, marital status, distance from clinic, severity of illness (as measured by physician ratings, self-health assessment, number of medications, number of diagnoses, and number of clinic visits and hospitalizations in the prior year), and physician expectations of improvement were entered as predictors into stepwise multiple regression analyses for the elderly and the young. Predictors of better satisfaction in the young were less severe conditions, being nearer to the clinic and having fewer prior clinic visits over the year. In the elderly, having fewer visits to the clinic, more expectation of improvement by the physician and less severe conditions were associated with better satisfaction. Severity and clinic visits were predictors in each age group. The young, however, were also influenced by distance from the clinic. The elderly were influenced separately by the physician's prognosis. Thus, when the more impaired elderly are seen frequently without expecting a benefit, their satisfaction with care is poor. Further, satisfaction with care was correlated significantly with compliance in the elderly but not in the young. Findings suggest that improving satisfaction with care might also improve rates of compliance with the medical regimen in older patients.

Beliefs about causes of cancer in cancer patients.

Beliefs about causes of cancer were studied in 120 patients with late-stage cancer and compared with beliefs of non-cancer patients matched for age, sex, and hospitalization. Cancer patients consistently had less strong beliefs about causes of cancer than did the other groups, even when causes such as smoking and having pulmonary cancer were probably associated with the development of their disease. Although some correlates of beliefs were found in cancer patients' personal and social background, these were generally of minimal levels of statistical significance. Those who had been diagnosed longer believed cancer was more often inherited. The non-cancer patients' beliefs were similar to those found in a large survey of the general population. It is likely that cancer patients need to defend themselves against self-blame as a means of coping with a terminal illness.

Effectiveness of a Service Workers' Action Team (SWAT) for the elderly.

The Service Workers Action Team (SWAT) is a three-year, community-based demonstration project for the elderly, with the primary goal of improving or maintaining psychosocial and physical functioning. With baseline scores and selected demography data os covariates, 243 experimental SWAT recipients were compared (MANOVA) with 158 controls after six months, with respect to: 1) Hopkin's Symptom Checklist, 2) Social Participation Scale, 3) Life Satisfaction Scale, 4) Self-Esteem Scale, 5) Activities of Daily Living, and 6) four selected health-related questions. The frequency of responses for the experimental elderly were computed for program satisfaction at the time of follow-up. In terms of psychosocial functioning, the experimental group fared significantly better at six months than did the control group. In terms of health, both groups declined in functional status, as evidenced by their scores on Activities of Daily Living, though the experimental subjects still were significantly better than the controls. The majority of the experimental group found the program to be helpful, with suggestions made for program expansion.

High speed frequency modulation of far infrared lasers using the Stark effect.

Electronic frequency tuning of an optically pumped far infrared waveguide laser has been achieved by using the Stark effect. Frequency modulation with a 50-kHz modulation frequency and an index greater than 1 has been observed as well as a maximum modulation frequency of 300 kHz.

Methods and rationale for closed treatment of Achilles tendon ruptures.

A method of closed treatment of Achilles tendon ruptures by casting, utilizing a long leg cast for 6 weeks and a short leg cast for 4 additional weeks, is presented. An experimental model using rabbits supports the clinical contention that closed approximation and immobilization of Achilles tendons allows tendon healing to progress, at least in the early stages. Observations made on the tendon sheath during early healing attribute a very positive role to it in providing needed blood supply to the tendon. The importance of maintaining a smooth gliding surface as well suggests that the tendon sheath should not be violated by surgical repair on the Achilles tendon.

Closed treatment of Achilles tendon ruptures.

A method of closed treatment of ruptures of the Achilles tendon is advocated. This system provides for a period of casting for ten weeks, eight of which are with the foot immobilized in gravity equinus. The use of a long leg cast for the first six weeks is justified to allow relaxation of the gastrocnemius muscle. Clinical evaluation and experience in treating eight patients reveal a consistently good result with a minimum of complications. The inherent risks of anesthesia and surgery are avoided. The postoperative problems associated with surgery on the Achilles tendon are not present.

Treatment of coccidioidomycosis infection of bone with local amphotericin B suction-irrigation. Report of a case.

A 29-year-old man with coccidioidomycosis of the tarsal bones and toxic reactions to intravenous Amphotericin B was treated by surgical curettage and local suction-irrigation system of Amphotericin B. The patient responded to treatment and was free of disease 2 years later. Local suction-irrigation with Amphotericin B may be a valuable adjunct in the treatment of coccidioidomycosis infection of bone.
