Complementary medicine: legal status of the non-licensed provider in the USA.

European providers of complementary medicine may be surprised by the formal strictures which their US counterparts face. A major hurdle to holistic practice in the USA is the statutory prohibition against the unlicensed practice of medicine. State statutes define 'medicine' broadly, creating a legal risk for unlicensed providers of holistic health care, as well as for licensed providers whose services are deemed to exceed their legislatively authorized scope of practice and cross into 'diagnosis' and 'treatment' of disease. This paper does not address scope of practice; rather, it focuses on the legal status of non-licensed (or 'unenfranchised') providers. For these providers, seeking occupational licensure will provide some protection against medical practice acts, as well as opportunity to elevate professional competence and prestige. However, many holistic providers prefer to remain outside the regulatory scheme. Mandatory licensure, title licensure and registration offer means of upgrading professional status and achieving state sanction for professional practice.

Clinical experience with one hundred consecutive patients undergoing orthotopic heart transplantation with bicaval and pulmonary venous anastomoses.

OBJECTIVE: Our objective was to assess survival, need for pacemaker insertion, and rejection frequency with a new surgical technique of orthotopic heart transplantation using bicaval and pulmonary venous anastomoses. METHODS: We retrospectively reviewed 100 consecutive patients who had orthotopic heart transplantation with this technique between July 1991 and September 1995. RESULTS: The mean age was 57.0 +/- 11.1 years, with 51 patients being 60 years or older. The mean donor/recipient weight ratio was 0.92, and in 28 patients the ratio was less than 0.8. The early (30-day) survival was 100% and the 1- and 2-year survivals were 98% +/- 2% and 96% +/- 2%, respectively. Survival was not affected by age or by the duration of the OKT3 therapy (p > 0.2 for each of these parameters). The seven late deaths were due to infection (n = 2), graft atherosclerosis (n = 3), acute rejection (n = 1), and nonspecific graft failure (n = 1). No permanent pacemaker was required in the first 6 months after the operation, and all the patients were discharged in normal sinus rhythm. Freedom from treated rejection was significantly greater in patients with 7 days of OKT3 therapy than in patients with 14 days of therapy (p < 0.0001). CONCLUSIONS: Orthotopic heart transplantation with bicaval and pulmonary venous anastomoses offers an improved alternative to the standard biatrial technique, with a 30-day mortality of 0,% in 100 consecutive patients, excellent intermediate-term survival, and elimination of the need for pacemaker insertion. More normal anatomic configuration and synchronous function of the atria may have contributed to these results.

The stages of the prediagnostic period in chronic, life-threatening childhood illness: a process analysis.

This is one of a series of articles explicating a theory of family behavior under conditions of sustained uncertainty brought about by the diagnosis of a chronic, life-threatening illness of a child. The procedures of the grounded theory method were used to collect and analyze data. The analysis illuminated a perceptual-interpretive-behavioral process that made visible the emergence and intensification of the uncertain state during the prediagnostic period. This process, which may consist of up to three stages, most frequently began with the parents' initial awareness of the child's illness cues and terminated with the diagnostic announcement. The stages were categorized as Lay Explanatory (I), Legitimating (II), and Medical Diagnostic (III). The duration of stage III was found to be a significant factor in explaining the variation in parental response to the diagnosis.

Legal ramifications of homeopathy.

The article addresses four regulatory challenges faced by practitioners of homeopathy: (1) medical practice acts, which prohibit the unlicensed practice of "medicine," (2) scope of practice limitations, which restrict nonmedical providers' ability to diagnose and treat disease; (3) prohibitions against "unprofessional conduct;" and (4) malpractice rules. The article concludes with suggestions for regulatory reform.

Nocardiosis after corticosteroid therapy for malignant thymoma.

BACKGROUND: Nocardia asteroides is an opportunistic infection caused by an aerobic actinomycete, which, in the immunocompromised host, can be associated with severe invasive disease with a predilection for the brain. METHODS AND RESULTS: The authors describe a 62-year-old man with a malignant thymoma that was clinically responsive to oral prednisone. N. asteroides sepsis subsequently developed, leading to his death. CONCLUSIONS: Nocardiosis should be considered a potential pathogen in this immunocompromised setting.

Cardiopulmonary responses to exercise in children with activity sensing rate responsive ventricular pacemakers.

The physiological benefits of activity sensing rate responsive ventricular pacing (VVIR) over fixed rate pacing (VVI) were investigated in 14 children during incremental cycle exercise. Based on their heart rhythm response during exercise, children were divided into two groups. Group I patients (13 +/- 4 years) remained in a paced-only rhythm when exercised. Group II patients (16 +/- 7 years) were paced at rest but converted to sinus rhythm with exercise. In Group I patients, the significant physiological benefits of VVIR over VVI pacing were evidenced by a 51% increase in peak heart rate (HRmax) and a 16% increase in exercise duration and maximum oxygen uptake (VO2max). Additionally, a 27% reduction in peak oxygen pulse (O2Pmax) was found, reflecting a similar decrease in stroke volume. The cardiorespiratory responses of Group I and II patients were compared in terms of percent of predicted normal values. Although Group I patients in the VVIR mode attained a better exercise performance than in the VVI mode and a normal O2Pmax (108% pred), their HRmax (62% pred) and VO2max (70% pred) fell far below normal values. In comparison, Group II patients, who went into sinus rhythm, achieved normal values for HRmax (84% pred), VO2max (90% pred), and O2Pmax (97% pred). The higher pacing rates attained by Group I patients in the VVIR mode may have allowed them to reach not only a higher cardiac output but also a more normal stroke volume at peak exercise than in the VVI mode.(ABSTRACT TRUNCATED AT 250 WORDS)
