The motivation to use complementary medicine healing methods. Study of a general internal medicine and orthopedic patient sample

436 patients from two different clinics of internal medicine and one orthopaedic unit were asked to fill a questionnaire on their attitude towards and use of alternative medicine. Of the 272 questionnaires returned, 235 could be used for analysis. 42.6% of all analysed persons confirmed use of alternative medicine. About half of them were motivated to do so by their nursing staff. Homeopathy was by far the most frequently used method. Persons who used alternative medicine were characterised by a distinct environmental awareness and regular sports activity. They had also often had positive experience of alternative methods in childhood. On the other hand, age, sex, education, duration of the treated disease and success of conventional therapy did not correlate significantly with the use of alternative medicine. An essential motive for the need to seek help by alternative therapists was the opinion that conventional forms of treatment would concentrate too much on the purely physical side of a health problem. All in all, users of alternative medicine did not seek confrontation with conventional medicine but rather sought a real complement to conventional forms of treatment.     

A randomized, double-blind study of the effect of olestra on disease activity in patients with quiescent inflammatory bowel disease. Olestra in IBD Study Group

PURPOSE: To determine the effects of olestra, a zero-calorie fat substitute that is neither digested nor absorbed, on the well-being and disease state of persons with chronic inflammatory bowel disease (IBD) in remission. PATIENTS AND METHODS: Eighty-nine patients with mild to moderate ulcerative colitis (n = 43) or Crohn's disease (n = 46) in remission, with a history of disease of 2 years or longer, were enrolled in this prospective study from nine private practices, three university-based medical centers, and one Veterans Administration medical center in the United States. Forty-four patients were randomly assigned to receive olestra and 45 to receive triglycerides in chips or cookies daily for 4 weeks. At Week 4, patients were classified as in remission, worsened, or relapsed according to an investigator's global assessment based on sigmoidoscopy (for ulcerative colitis) or the Crohn's disease activity index, laboratory findings, and clinical course. RESULTS: At Week 4, the olestra and triglyceride groups did not differ significantly with respect to the percentages of patients who relapsed (P = 0.494; difference = 2.4%; upper 95% CL = 8.8%) or with respect to the percentages of patients who experienced any worsening of their symptoms (P = 0.630; difference = 0.2%; upper 95% CL = 13.3%). Of evaluable patients, 90% (37 of 41) given olestra remained in remission with no worsening, compared with 90% (38 of 42) given triglycerides. Gastrointestinal symptoms were comparable between the treatment groups, and there were no treatment-related laboratory abnormalities. Six patients were excluded from analysis for reasons unrelated to treatment. CONCLUSION: Olestra did not affect the activity of quiescent mild to moderate IBD.     

Allogeneic hemopoietic stem cell transplantation for patients with high risk acute lymphoblastic leukemia: favorable impact of chronic graft-versus-host disease on survival and relapse

BACKGROUND AND OBJECTIVE: The best post-remission therapy for patients with acute lymphoblastic leukemia (ALL) is controversial, and hemopoietic stem cell transplantation (HSCT) is one therapeutic option. The goal of this study is to describe long term results of HSCT in high risk ALL patients. DESIGN AND METHODS: Between 1978 and 1996, 170 patient with ALL and a median age of 22 years (1-49), underwent an allogeneic HSCT from HLA-identical siblings (n = 149), family mismatched donors (n = 18) or unrelated HLA matched donors (n = 3); 92% of patients had at least one adverse prognostic factor for high risk ALL at diagnosis; one third (33%) were in first remission (CR1) and the majority (85%) received an unmanipulated HSCT with cyclosporin-methotrexate prophylaxis of graft-versus-host disease (GvHD). RESULTS: After a median follow-up of over 6 years, 59 patients are alive and 111 patients have died of leukemia (46%) or transplant related complications (54%). The actuarial 10 year survival is 53%, 38% and 20%, for patients in CR1, CR2 or advanced phase, respectively. The actuarial survival of patients with (n = 24) of without (n = 46) cytogenetic abnormalities, grafted in CR1/CR2 was respectively 45% and 48% (p = 0.5). The year of transplant had a significant impact in multivariate analysis on transplant related mortality (TRM) (p = 0.0009) but not on relapse (p = 0.3). Chronic GvHD was the most important favorable prognostic factor for survival (p = 0.0014) and relapse (p = 0.0019). INTERPRETATION AND CONCLUSIONS: This study confirms that long term survival can be achieved with HSCT in ALL patients, even those with cytogenetic abnormalities. Transplant mortality has been significantly reduced in recent years, whereas leukemia rate relapse has remained unchanged: the latter is influenced by the occurrence of chronic GvHD. Immune intervention post-HSCT may be considered to address this problem.     

In vivo purging with high-dose cytarabine followed by high-dose chemoradiotherapy and reinfusion of unpurged bone marrow for adult acute myelogenous leukemia in first complete remission

PURPOSE: To evaluate in a prospective study the efficacy of autologous bone marrow transplantation (BMT) in adult patients with acute myelogenous leukemia (AML) in first remission, using a single course of high-dose Cytarabine (HD Ara-C) consolidation therapy as in vivo purging. PATIENTS AND METHODS: Sixty consecutive adult patients with AML in first complete remission (CR) were treated with HD Ara-C consolidation therapy as a method of in vivo purging before marrow collection. High-dose therapy consisted of fractionated total-body irradiation (FTBI) 12 Gy, intravenous etoposide 60 mg/kg, and cyclophosphamide 75 mg/kg, followed by reinfusion of cryopreserved marrow. RESULTS: Sixty patients underwent consolidation treatment with HD Ara-C with the intent to treat with autologous BMT. Sixteen patients were unable to proceed to autologous BMT (10 patients relapsed, one died of sepsis, one developed cerebellar toxicity, two had inadequate blood counts, and two refused). Forty-four patients underwent autologous BMT and have a median follow-up time of 37 months (range, 14.7 to 68.7) for patients who are alive with no relapse. The cumulative probability of disease-free survival (DFS) at 24 months in the intent-to-treat group is 49% (95% confidence interval [CI], 37% to 62%) and in those who actually underwent autologous BMT is 61% (95% CI, 46% to 74%). The probability of relapse was 44% (95% CI, 31% to 58%) and 33% (95% CI, 20% to 49%) for the intent-to-treat and autologous BMT patients, respectively. CONCLUSION: This approach offers a relatively high DFS rate to adult patients with AML in first CR. The results of this study are similar to those achieved with allogeneic BMT.     

Autologous stem-cell transplantation for non-Hodgkin's lymphomas: the role of graft purging and radiotherapy posttransplantation--results of a retrospective analysis on 120 patients autografted in a single institution

PURPOSE: To analyze retrospectively survival and prognostic factors of patients with non-Hodgkin's lymphoma (NHL) autografted from 1979 to 1995 in a single institution. PATIENTS AND METHODS: A total of 120 patients, 64 with aggressive and 56 with low-grade NHL, were autografted. The carmustine (BCNU), etoposide, cytarabine, and melphalan (BEAM) regimen was used in 104. The autograft was marrow in 101 patients. Marrow was purged in vitro by mafosfamide for 63 patients (adjusted dose [AD] in 32; unique dose [UD] in 31); 27 patients received a CD34+-selected graft. Following intensification, 45 patients received additional radiotherapy on previous sites of involvement. RESULTS: Outcome at 5 years for patients transplanted with low-grade NHL in first complete remission (CR1), in first partial remission (PR1), and in second complete remission (CR2) or beyond showed an event-free survival (EFS) of 75% +/- 12%, 46% +/- 18%, and 57% +/- 24%, a relapse incidence (RI) of 21% +/- 12%, 49% +/- 19%, and 43% +/- 25%, and a transplant-related mortality (TRM) of 5% +/- 5%, 10% +/- 7%, and 0%, respectively. For patients with aggressive NHL transplanted in CR1, in PR1, in CR2 or beyond, and in resistant relapse or in primary refractory disease, the EFS was of 73% +/- 9%, 58% +/- 19%, 29% +/- 16%, and 10% +/- 9%, the RI 22% +/- 9%, 14% +/- 9%, 77% +/- 18%, and 66% +/- 20%, and the TRM 6% +/- 6%, 32% +/- 21%, 11% +/- 10%, and 71% +/- 22%, respectively. In patients autografted upfront in first remission, additional radiotherapy was associated with a higher EFS, in univariate (P = .03) and multivariate analysis (P = .02, relative risk [RR] = .021). The role of graft purging with mafosfamide on the outcome reflected by the dose of colony-forming unit-granulocyte-macrophage (CFU-GM) per kilogram infused postpurging was assessed by univariate analysis: patients in first remission who received lower doses of CFU-GM had a lower RI and a higher EFS. CONCLUSION: This retrospective analysis suggests that marrow purging and posttransplant radiotherapy improve the outcome of patients with NHL autografted in first remission.     

The efficacy of polychemotherapy programs in treating multiple myeloma patients

AIM: To compare efficiency of the programs MCVP, VCAP and ARA-COP in the treatment of multiple myeloma (MM) as regards completeness of the response, duration of the remission and toxicity. MATERIALS AND METHODS: A total of 41 MM patients entered the study (27 females, 14 males, age from 41 to 72 years, MM duration from 1 month to 8 years). 16, 10 and 15 patients were treated according to MCVP, VCAP and ARA-COP programs. RESULTS: Both in the resistant and primary patients the response was the highest to ARA-COP treatment. The remission or stabilization was achieved in 93.4% of patients. VCAP program was less effective. However, clinicohematological remission was achieved in 50% of patients. This program is rather heart toxic. MCVP program was the least effective. Survival was followed up in 16 patients (10 MCVP, 3 VCAP and 3 ARA-COP patients). The survival was 20-62, 16-36, 23.6-64.8 months for ARA-COP, VCAP and MCVP, respectively. CONCLUSION: ARA-COP program proved most effective of the three programs both in primary and drug-resistant patients. VCAP and MCVP programs are less effective but can be used in primary management of MM patients.     

Concordance in communication between surgeon and patient

PURPOSE: To describe adolescents' and young adults' knowledge about their health insurance, and to identify factors associated with correct knowledge of health insurance in this population. METHODS: Data were analyzed from a confidential questionnaire administered to 830 patients at a hospital-based adolescent medicine clinic. The questionnaire contained items pertaining to insurance type, demographics, health status, and health-risk behaviors. Actual health insurance data and information regarding utilization of health services were obtained from the hospital billing data-base. Predictors of health insurance knowledge were determined through bivariate analyses followed by stepwise logistic regression. RESULTS: A total of 50.7% of respondents correctly identified their type of health insurance. Those who correctly identified their insurance had a higher mean age. Only 48.5% of participants who were 11-18 years old could identify their insurance type, versus 53.1% of 19-21-year-olds and 64.7% of 22-24-year-olds (p = 0.02). Sixty-five percent of Medicaid patients and 76.3% of hospital free care patients knew how their medical bills were paid, versus 17.9% of self-pay patients and 47.3% of patients with private insurance (p < 0.01). Greater utilization of health services was associated with increased rates of insurance knowledge among 19-24-year-olds on bivariate analysis; however, this factor was not significant when controlling for other factors. Regression analysis revealed that older age and insurance type other than self-payment were independent predictors of health insurance knowledge in adolescents (11-18 years old), while female gender and insurance type other than self-payment were independent predictors of insurance knowledge in young adults (19-24 years old). CONCLUSIONS: Approximately half of adolescents and young adults do not know how their medical bills are paid. Validation of self-reported insurance data is, therefore, critical both in clinical practice and health services research.     

Transsphenoidal microsurgical therapy of prolactinomas: initial outcomes and long-term results

OBJECTIVE: Prolactinomas are frequently treated primarily with dopamine agonists; however, these agents have disadvantages and require life-long therapy. We therefore reassessed transsphenoidal microsurgery as an alternative therapy. METHODS: We reviewed the data for 121 female patients treated surgically for prolactinomas between 1976 and 1979 (Group 1) and 98 patients treated between 1988 and 1992 (Group 2). RESULTS: Of 219 women, 92% with preoperative prolactin (PRL) values of < or = 100 ng/ml and 91% with intrasellar microadenomas experienced initial remission; 80 to 88% of patients with intrasellar macroadenomas or macroadenomas showing moderate suprasellar extension or focal sphenoid sinus invasion experienced remission. Women with PRL values of > 200 ng/ml and those with larger and more invasive adenomas experienced poorer outcomes (37-41% remission). Lower preoperative PRL values and adenoma stage were the best predictors of initial surgical outcomes. At the most recent evaluations, 89% of women who experienced initial remission continued to experience clinical remission; 85% exhibited normal PRL values, and 5% demonstrated mild, asymptomatic, recurrent hyperprolactinemia (PRL values of < 34 ng/ml). In Group 1, 84% of patients continued to experience remission (82% with normal PRL values) after a median follow-up period of 15.6 years. In Group 2, 97% of patients continued to experience remission (88% with normal PRL values) after a median follow-up period of 3.2 years. Lower postoperative PRL values were the best predictors of long-term remission. CONCLUSION: Transsphenoidal microsurgery is an effective alternative to long-term medical therapy for selected patients with prolactinomas. Successful outcomes and long-term remission were achieved in patients with microadenomas and noninvasive macroadenomas.     

The use of ungating with the Medstone lithotriptor

PURPOSE: Ungating using the Medstone* lithotriptor by 200 urologists was evaluated. MATERIALS AND METHODS: During 1994, 3,288 patients were treated by 200 urologists at 46 sites in 6 upper midwest states using 5 fixed and 3 mobile Medstone lithotriptors. Ungating was used with 58 treatments in 57 asymptomatic patients (1.8%) due to irregular cardiac rhythm in 48 caused by a bundle branch block (11), atrial fibrillation (10), slow heart rate (6) and irregular cardiac complex (21); all 48 cases were clinically insignificant, and because of urologist choice in 9 with normal cardiac rhythm (10 treatments). The cardiac simulator used for ungated lithotripsy was set at 85 shocks per minute for irregular cardiac rhythm and at 120 shocks per minute for elective use. RESULTS: The 48 treatments in patients with clinically insignificant irregular cardiac rhythm (average age 66.4 years) were performed during an average of 41 minutes of shock time. One patient had clinically significant cardiac arrhythmia that resolved with gating. The 10 elective treatments were performed during an average of 34 minutes of shock time in patients an average of 60.4 years old. The 3,231 gated treatments were performed during an average of 40 minutes of shock time in patients an average of 51 years old. CONCLUSIONS: Ungating was safe and effective in allowing patients with an irregular cardiac rhythm to be treated with the same shock time as gated cases (normal cardiac rhythm).     

Chronic hepatitis B and C in HIV-infected patients

BACKGROUND AND AIM: This retrospective study examined the prevalence of co-infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) and the frequency of chronic hepatitis in HIV-infected patients with respect to both the different risk groups and the serological results. PATIENTS AND METHODS: All Zurich participants of the Swiss HIV Cohort Study were evaluated who had available results of hepatitis B and C serology and ALT. RESULTS: Of the total 279 patients, 52% belonged to the intravenous drug user, 34% to the homosexual, and 11% to the heterosexual risk category. Serologically, previously acquired infection with HBV alone could be demonstrated in 92 (33%), HCV alone in 9 (3%), and both HBV and HCV in 130 (47%) patients. Only 3% of patients with sexually acquired HIV infection had anti-HCV antibodies, whereas co-infection with HBV and HCV was present in 87% of intravenous drug users. Among the 222 patients with previous HBV contact, 25 (11%) had positive HBsAg and 91 (41%) had "anti-HBc alone", both assumed to represent active HBV infection. 66 (24%) of 279 patients had chronic hepatitis with ALT elevation lasting > or = 6 months. Chronic hepatitis was present in 46% of those with active HBV and HCV co-infection, in 36% of those with HCV infection alone and in 18% of those with active HBV infection alone (P < 0.001). Of the 66 cases of chronic hepatitis, 58 were associated with HCV infection, and only 2 cases had no serological signs of active HBV or HCV infection. CONCLUSION: In patients with sexually acquired HIV infection, HBV had frequently been co-transmitted. In contrast, almost all of those infected by means of intravenous drug use had a co-infection with both HBV and HCV. The latter seems to play the strongest role in the development of chronic hepatitis with persistent ALT elevation. A chronic ALT elevation was almost always associated with serologically active HBV or HCV infection.     

Needle-knife papillotomy: a helpful and safe adjunct to endoscopic retrograde cholangiopancreatography in a selected population

BACKGROUND AND STUDY AIMS: Needle-knife papillotomy (NKP) has been shown to be a useful alternative when standard techniques fail to provide access during ERCP. A retrospective review was conducted to reevaluate the indications, efficacy, and complications of NKP at a tertiary referral center. PATIENTS AND METHODS: A total of 1205 therapeutic endoscopic retrograde cholangiography procedures (ERCPs) were reviewed. Sixty-eight patients (5.6%) had undergone NKP after an established algorithm of techniques had failed to provide access. The NKP results were analyzed in two periods, including initial experience with 470 ERCPs (group 1, NKP n = 22) and later experience with 735 patients (group 2, NKP n = 46). RESULTS: Immediate free cannulation in group 1 was achieved in 14 of 22 patients (64%), vs. 34 of 46 (74%) in group 2. The delayed cannulation rate was five of eight patients in group 1 (62.5%) vs. 11 of 12 in group 2 (92%). The success rate was 19 of 22 patients in group 1 (86%) vs. 45 of 46 in group 2 (98%). The overall success rate was 64 of 68 (94%). Successful cannulation led to a therapeutic intervention in 94% of these patients. A complication rate of 6%, without mortality, was noted. CONCLUSIONS: NKP is a valuable tool that allows a high success rate for cannulation, with a low complication rate. The success rate increases with operator experience. NKP should be carried out by experienced endoscopists after standard maneuvers fail to provide access, and when cannulation is likely to be followed by a therapeutic intervention.     

Alternative medicine use by homeless youth

BACKGROUND: Mainstream health care for homeless youth is often fragmented or unavailable. OBJECTIVE: To evaluate the use of complementary and alternative medicine (CAM) by homeless youth who use our free clinic. DESIGN: Self-administered cross-sectional survey. SUBJECTS AND METHODS: Subjects included homeless youth between the ages of 14 and 21 years receiving care at the 45th Street Clinic Youth Program in Seattle, Wash, between January 29,1998, and March 5, 1998. The self-administered survey included items on demographics, health issues, use frequency of different therapists or therapies, referral sources, and perceived effectiveness of treatment. RESULTS: The response rate by patients was 96.3% (157/163) with an average respondent age of 18.5 years (range, 14-21 years). Complementary and alternative medicine was used by 70.1% of the subjects. Referrals most often came from friends (52.7%). The most common reason for using CAM was because it was "natural" (43.9%). Most of those who used alternative therapies (87.3%) believed they had been helped "some" or "a lot." Given a choice of providers to visit when they were ill, 51.7% would seek care from a physician, 36.9% from a CAM provider, and 11.4% would treat themselves. CONCLUSIONS: Care with CAM is frequently used and accepted by homeless youth. Cost-effectiveness and contributions to overall health care require additional evaluation. Integrating CAM into allopathic health centers may serve as an incentive to entice youth into mainstream health care.     

Use of alternative therapies by rehabilitation outpatients

OBJECTIVE: To document the prevalence and patterns of use of alternative medical therapies as well as their perceived effectiveness by patients in a rehabilitation medicine outpatient practice. DESIGN: Cross-sectional survey by written questionnaire. SETTING: An urban rehabilitation medicine outpatient referral office. PATIENTS: A random sample of 103 patients referred for rehabilitation outpatient care, while waiting for their appointment, were given a questionnaire addressing their use of alternative therapies. MAIN OUTCOME MEASURES: Use of alternative therapies and their perceived effectiveness. RESULTS: One or more alternative medical therapies had been used by 29.1% of subjects in the past 12 months for their presenting problem. The most common therapies were massage, chiropractic, vitamin and mineral supplementation, and acupuncture. Musculoskeletal pain syndromes involving the spine and extremities were the most common problems for which patients sought both physiatric and alternative care. Of the patients who used alternative treatments 53% reported some degree of efficacy. CONCLUSIONS: A significant proportion of rehabilitation medicine patients use and frequently perceive a benefit from alternative therapies, particularly massage, chiropractic, vitamin and mineral supplementation, and acupuncture. Incorporating alternative therapies into physiatric practice is a desirable future direction for the specialty.     

Transthoracic needle biopsy of mediastinal lymph nodes for staging lung and other cancers

PURPOSE: To determine the usefulness of transthoracic needle biopsy of mediastinal lymphadenopathy for staging suspected lung and other cancers. MATERIALS AND METHODS: Transthoracic needle biopsy of the hilum or mediastinum was performed in 111 patients with suspected neoplasms. Most biopsy procedures were performed with computed tomographic guidance on an outpatient basis. Forty-eight adult patients had enlarged lymph nodes (defined as < or = 30 mm in the long axis and > or = 10 mm in the short axis). Sixty-three lesions larger than 30 mm were arbitrarily considered to be masses and were excluded. RESULTS: Carcinoma was diagnosed in 40 patients. Four patients had true-negative and one patient had false-negative results. Sensitivity for carcinoma was therefore 98% (40 of 41). One patient with a negative biopsy result did not have surgical confirmation and was excluded from analysis. Lymphoma was excluded from analysis. Lymphoma was diagnosed in two patients (positive in one and suspicious in one). Pneumothorax occurred in 19 (34%) of 56 biopsy procedures. Chest tube treatment was required in eight (14%). CONCLUSION: Transthoracic needle biopsy of mediastinal lymphadenopathy is a safe, accurate diagnostic staging procedure. It can frequently be used as an alternative to mediastinoscopy in patients with lymphadenopathy.     

Mantle-cell lymphomas have more widespread disease and a slower response to chemotherapy compared with follicle-center lymphomas: results of a prospective comparative analysis of the German Low-Grade Lymphoma Study Group

PURPOSE: To compare mantle-cell lymphomas (MCLs) and follicle-center lymphomas (FCLs) for their features of clinical presentation, response to chemotherapy, and prognosis on the basis of a prospective randomized clinical trial. PATIENTS AND METHODS: Patients with MCL and FCL who entered onto the prospective randomized comparison of cyclophosphamide, vincristine, and prednisone (COP) versus prednimustine and mitoxantrone (PmM) followed by a second randomization for interferon (IFN) maintenance versus observation only. RESULTS: One hundred sixty-five of 234 patients had FCL and 45 of 234 patients had MCL. With FCL, both sexes were equally affected (men, 47%); patients with MCL were predominantly men (78%; P < .0004) and had a higher median age (64 v 53 years; P < .0001). Patients with MCL also had more widespread disease, reflected by the proportion of patients with two or greater extranodal manifestations (43% v 21%; P < .005) and nine or greater involved nodal areas (64% v 45%; nonsignificant [NS]). Response to chemotherapy was significantly lower in patients with MCL (complete remission [CR] + partial remission [PR], 69% v 88%; P < .05) and occurred at a slower pace. Patients with MCL also had a shorter event-free interval (median, 8 v 24 months; P < .0001) and overall survival (median, 28 v 77 months; P < .0001). In both subtypes, however, patients with less than two residual lymphoma manifestations in remission experienced a relatively good prognosis with an estimated 5-year survival of greater than 60% for MCL and greater than 75% for FCL. CONCLUSION: MCL and FCL differ substantially in their features of presentation, response to chemotherapy, and long-term prognosis. The extent of residual disease after completion of chemotherapy discriminates patients with different prognosis and may be used for the stratification of postremission strategies.     

Long-term results after allogeneic bone marrow transplantation for chronic myelogenous leukemia in chronic phase: a report from the Chronic Leukemia Working Party of the European Group for Blood and Marrow Transplantation

The purpose of this study was to determine the long-term results of allogeneic bone marrow transplantation for chronic myeloid leukemia. A retrospective analysis was carried out of the outcome of 373 consecutive transplants performed at 38 European institutions between 1980 and 1988 and reported to the registry of the European Group for Blood and Marrow Transplantation. All transplants were carried out for first chronic phase of chronic myelogenous leukemia using unmanipulated marow cells from HLA-identical sibling donors. The probability of survival and leukemia-free survival at 8 years were 54% (95% CI: 49-59) and 47% (95% CI: 41-52) respectively. The probabilities of developing acute GVHD (II-IV) at 100 days and chronic GVHD at 4 years after transplant were 47% (95% CI: 41-53) and 52% (95% CI: 46-58) respectively. The probabilities of transplant-related mortality and leukemic relapse 8 years after BMT were 41% (95% CI: 36-48) and 19% (95% CI: 14-25), respectively. Transplant within 12 months of diagnosis was associated with reduced transplant-related mortality (34 vs 45%, P = 0.013) and resulted in improved leukemia-free survival (52 vs 44%, P = 0.03). The probability of relapse was significantly reduced in patients who developed chronic GVHD (RR = 0.33, P = 0.004). The probability of relapse occurring more than 2 years after transplant was increased more than five-fold in patients transplanted from a male donor (RR = 5.5, P = 0.006). Sixty-seven patients in hematologic remission were studied for residual disease by two-step RT/PCR for BCR-ABL mRNA and 61 (91%) tested negative. We conclude that bone marrow transplantation can induce long-term survival in approximately one-half of CML patients; the majority of survivors have no evidence of residual leukemia cells when studied by molecular techniques. The probability of late relapse is increased with use of a male donor.     

Why patients use alternative medicine: results of a national study

CONTEXT: Research both in the United States and abroad suggests that significant numbers of people are involved with various forms of alternative medicine. However, the reasons for such use are, at present, poorly understood. OBJECTIVE: To investigate possible predictors of alternative health care use. METHODS: Three primary hypotheses were tested. People seek out these alternatives because (1) they are dissatisfied in some way with conventional treatment; (2) they see alternative treatments as offering more personal autonomy and control over health care decisions; and (3) the alternatives are seen as more compatible with the patients' values, worldview, or beliefs regarding the nature and meaning of health and illness. Additional predictor variables explored included demographics and health status. DESIGN: A written survey examining use of alternative health care, health status, values, and attitudes toward conventional medicine. Multiple logistic regression analyses were used in an effort to identify predictors of alternative health care use. SETTING AND PARTICIPANTS: A total of 1035 individuals randomly selected from a panel who had agreed to participate in mail surveys and who live throughout the United States. MAIN OUTCOME MEASURE: Use of alternative medicine within the previous year. RESULTS: The response rate was 69%. The following variables emerged as predictors of alternative health care use: more education (odds ratio [OR], 1.2; 95% confidence interval [CI], 1.1-1.3); poorer health status (OR, 1.3; 95% CI, 1.1-1.5); a holistic orientation to health (OR, 1.4; 95% CI, 1.1-1.9); having had a transformational experience that changed the person's worldview (OR, 1 .8; 95% CI, 1 .3-2.5); any of the following health problems: anxiety (OR, 3.1; 95% CI, 1.6-6.0); back problems (OR, 2.3; 95% CI, 1 .7-3.2); chronic pain (OR, 2.0; 95% CI, 1.1 -3.5); urinarytract problems (OR, 2.2; 95% CI, 1.3-3.5); and classification in a cultural group identifiable by their commitment to environmentalism, commitment to feminism, and interest in spirituality and personal growth psychology (OR, 2.0; 95% CI, 1.4-2.7). Dissatisfaction with conventional medicine did not predict use of alternative medicine. Only 4.4% of those surveyed reported relying primarily on alternative therapies. CONCLUSION: Along with being more educated and reporting poorer health status, the majority of alternative medicine users appear to be doing so not so much as a result of being dissatisfied with conventional medicine but largely because they find these health care alternatives to be more congruent with their own values, beliefs, and philosophical orientations toward health and life.     

The distribution of visual attention in infants

This article compares the social and health characteristics of patients of five kinds of practitioners: family physicians (used as a baseline group); chiropractors; acupuncturist/traditional Chinese medicine doctors; naturopaths; and Reiki practitioners. The data were gathered in a large Canadian city during the period 1994 to 1995. Face-to-face interviews were conducted with 300 patients (60 from each type of treatment group). While the most striking social and health differences occur between patients of family physicians and the patients of alternative practitioners, significant differences are also evident between the different groups of alternative patients. Reiki patients, for example, have a higher level of education and are more likely to be in managerial or professional positions than other alternative patients. The profiles presented here indicate that users of alternative care should not be regarded as a homogeneous population. The findings also show that almost all alternative patients also consult family physicians. The pattern revealed is one of multiple use: patients choose the kind of practitioner they believe can best help their particular problem.     

Circadian secretion patterns of melatonin after major surgery

Despite our advances in the diagnosis and treatment of asthma, the incidence of mortality is increasing in developed countries. As patients and health care providers seek new options for the treatment and prevention of asthma, various complementary and alternative medical therapies are being used. With funding from the Office of Alternative Medicine, National Institutes of Health, our goal was to identify the type and prevalence of complementary and alternative treatments for asthma in use in the United States in order to establish a research agenda for the study of the most promising therapies. A survey was developed by an expert panel. After undergoing a preliminary round of testing and improvement, the survey was then sent along with a postage-paid return envelope as inserts in the May 1996 issue of Alternative Therapies in Health and Medicine, a peer-reviewed periodical of complementary and alternative medical research and scholarly activity; 10,000 surveys were distributed. We asked that only those who treated asthma respond. The surveys were designed to identify characteristics of the respondent, their particular practice type, use of complementary and alternative medicine, or conventional medicine in general, patient characteristics and numbers, and their use of 20 specific potential therapies to treat asthma. A total of 564 surveys were returned. The 5.64% response rate was low but was reflective of the demographics of the readership of this journal of complementary and alternative medicine. The survey population was 46% male and 43% female; 11% did not specify gender. They ranged in age from under 31 years old to over 70. The largest group (37%) of respondents held degrees as medical doctors, 27% held doctorates in complementary and alternative medicine related disciplines, 11% had registered nursing degrees, 4% were acupuncturists and 18% did not specify their training. Practice characteristics between MD and non-MD asthma care providers did not differ. The majority had general practices (75%) seeing all ages of patients. MDs were less likely to employ complementary and alternative medicine techniques for asthma compared to non-MDs. Both groups identified dietary and nutritional approaches as their most prevalent and useful asthma treatment option. Use of botanicals, meditation and homeopathy were frequently cited; statistically significant differences appeared in the rankings of treatment usefulness and prevalence between MD and non-MDs. Non-MD asthma care providers were more likely to ask patients about their use of complementary and alternative treatments for asthma than MDs (92% vs. 70%), while both groups showed statistically significant increases in their levels of patient inquiries compared to 2 years previously (up 9% and 8% for MDs and non-MDs respectively). The predominance of diet and nutrition supplementation used by MDs and non-MDs suggests that further attention and research efforts should be directed toward this area of complementary and alternative practice. Other complementary and alternative medicine practices such as botanicals, meditation and homeopathy appear to warrant research efforts. Differences between MDs and non-MDs in their use of such therapies may reflect different philosophies as well as training.
