[Mental Distress and Resilience in Severe Somatic Diseases: An Analysis of Dyadic Relations]. / Psychische Belastung und Resilienz im Rahmen schwerer körperlicher Erkrankungen: eine Analyse dyadischer Zusammenhänge.

AIMS: In this article, we present 3 studies examining patients with current or previous severe physical illness and their partners with respect to dyadic concordance, gender and role differences in mental distress and resilience. METHODS: Study 1 included 55 patients and their partners on average 4.5 years after severe sepsis. Study 2 involved 49 patients with lung cancer, predominantly in advanced stage with metastases, and their partners. In study 3, 69 cancer patients with various tumor entities and tumor stages undergoing additional outpatient homeopathic treatment as well as their partners were examined. All studies used the Hospital Anxiety and Depression Scale (HADS) to measure mental distress and the short version of the Resilience Scale RS-13 to assess resilience as a personality trait. Results were meta-analytically pooled across the 3 studies. RESULTS: We found dyadic concordances between patient and partner in anxiety (r=0.29 [0.06; 0.48], I2=55%) and depression (r=0.44 [0.31; 0.55], I2=0%), but not in resilience. Gender differences emerged consistently across all three studies, both female patients and partners showed more severe anxiety symptoms than males (d=0.58 [0.26; 0.91], I2=0% for patients; d=0.53 [- 0.06; 1.12], I2=69% for partners). Results were heterogeneous for gender differences in depression and for role differences. Higher resilience scores were associated with lower mental distress both in patients and partners. There is some evidence that resilience has a protective effect for mental distress of the spouse. DISCUSSION AND CONCLUSION: Based on the results on dyadic concordance between patients and partners in mental distress somatic diseases should always be considered from a systemic perspective. Mental distress of both patients and partners requires special attention in psychosocial support, and partnership resources should be taken into account for coping with the disease.

Do sociodemographic characteristics associated with the use of CAM differ by chronic disease?

BACKGROUND: Complementary and alternative medicine (CAM) is oftenused to alleviate the discomfort, disability and pain involved in many chronic diseases. Besides this, females, middle-aged and higher educated people are also known to use CAM the most. This study explores whether the sociodemographic characteristics associated with CAM use differ by type of disease. METHODS: The following data were taken from the Belgian Health Interview Survey 2013 for the individuals aged 15+ years (n = 8942): sociodemographic characteristics, past 12-month diseases (using a list) and contact with a homeopath, chiropractor, acupuncturist and/or osteopath (CAM-therapists) in the past year. The association between CAM use and disease, controlled for gender, age, education and conventional medicine use, was assessed through logistic regressions. When interactions with the sociodemographic characteristics were found, stratified regressions were conducted. RESULTS: People with musculoskeletal diseases [odds ratio (OR) = 2.6], allergy (OR = 1.4) and severe headache (OR = 1.5) had higher odds of using CAM in the past year with statistical significance. For musculoskeletal diseases, the odds of using CAM was higher, with statistical significance, for every sociodemographic subclass. For allergy, CAM use was higher among men, people aged 45+ years and lower educated people, while for severe headache CAM use was higher among women, people aged 45+ years and higher educated people, all with statistical significance. CONCLUSIONS: Sociodemographic characteristics associated with CAM use differ by diseases. The role of CAM in disease management cannot be ignored. Making physicians aware for which disease CAM is used and by whom, may facilitate disease management.

Use of complementary and alternative medicine in patients with health complaints attributed to former dental amalgam fillings.

BACKGROUND: The dental filling material amalgam is generally well tolerated. However, a small proportion of dental patients experience health complaints which they attribute to amalgam. The symptom pattern is often similar to patients with medically unexplained physical symptoms (MUPS) and the health complaints may persist after amalgam removal. Among patients with MUPS, the use of complementary and alternative medicine (CAM) seems to be high. The aim of this survey was to describe the prevalence and range of CAM use among people with health complaints attributed to dental amalgam fillings in which the health problems persist after the removal of all amalgam fillings. Specific attention was paid to (1) self-reported effects of CAM, (2) differences in CAM use dependent on self-reported health, and (3) gender differences in self-reported CAM use. METHODS: A survey was distributed to all members of The Norwegian dental patient association (NDPA) (n = 999), the response rate was 36.4%. The anonymous questionnaire asked for socio-demographic data, health complaints related to former amalgam fillings, subjectively perceived health status, symptoms, and experience with therapeutic interventions, mostly from the spectrum of CAM. Only participants who had all their fillings removed, which was the vast majority, were analysed. RESULTS: A total of 88.9% of included respondents had used at least one CAM modality, with a higher proportion of men (95.7%) compared to women (86.2%, p = 0.015). The most frequently used therapies were dietary supplements, vitamins and minerals recommended by a therapist (used by 66.7%) followed by self-prescribed dietary supplements, vitamins and minerals (59.0%), homeopathy (54.0%), acupuncture (48.8%) and special diets (47.5%). Use of CAM was similar for participants reporting normal to good health compared to participants reporting poor health. For all but two CAM modalities, the self-reported treatment effect was better in the group reporting normal to good health compared to the group reporting poor health. CONCLUSIONS: CAM was widely used by participants in our study, a finding similar to findings from studies of MUPS patients. To date, health problems associated with the use of dental amalgam is not an accepted diagnosis in the healthcare system. Consequently, people suffering from such complaints experience a lack of adequate treatment and support within conventional health care, which might have contributed to the high number of CAM users in this study.

Persons with allergy symptoms use alternative medicine more often.

INTRODUCTION: The aim of the study is to indicate the relation between the use of alternative medicine and the occurrence of allergic diseases in the Polish population of adults in the age of 20-44 years. Moreover the additional aim of the study is to define the relation between the sex, age and place of living and the use of alternative medicine. MATERIAL AND METHODS: The data from the project Epidemiology of Allergic Diseases in Poland (ECAP) has been used for analysis. This project was a continuation of the European Community Respiratory Health Survey II. The questions on alternative medicine were asked to the group of 4671 respondents in the age of 20-44 years. Additionally outpatient tests were performed in order to confirm the diagnosis of allergic diseases. RESULTS: The total of 22.2% of respondents that participated in the study have ever used alternative medicine (n = 4621). A statistically significant relation between the use of alternative medicine and declaration of allergic diseases and asthma symptoms has been demonstrated (p < 0.001). No statistically significant relation between the use of alternative medicine by persons diagnosed by a doctor with any form of asthma or seasonal allergic rhinitis (p > 0.05) has been demonstrated. CONCLUSIONS: The occurrence of allergic diseases and asthma influences the frequency of alternative medicine use. However the frequency of alternative medicine use does not depend on allergic disease or asthma being confirmed by a doctor.

Utilization of complementary and alternative medicine (CAM) among children from a German birth cohort (GINIplus): patterns, costs, and trends of use.

BACKGROUND: The use of complementary and alternative medicine (CAM) is widespread among children in Germany and other European countries. Only a few studies are available on trends in pediatric CAM use over time. The study's objective was to present updated results for prevalence, predictors, and costs of CAM use among German children and a comparison with findings from a previous follow-up of the same birth cohort. METHODS: Data were collected for 3013 children on their utilization of medicinal products (during the last 4 weeks) and consultation with CAM providers (in the preceding year) from a German birth cohort study (GINIplus, 15-year follow-up) using a self-administered questionnaire. The reported medicinal CAMs were classified into six categories (homeopathy, herbal drugs, nutritionals, minerals and trace elements, microorganisms, further CAM). Drug prices were traced using pharmaceutical identification numbers (PZNs), or otherwise conservatively estimated. Finally, the results were compared with data obtained from the 10-year follow-up of the same birth cohort study by adopting the identical methodology. RESULTS: In all, 26% of the reported 2489 drugs were medicinal CAM. The 4-week prevalence for homeopathy and herbal drug use was 7.5% and 5.6%, respectively. Some 13.9% of the children used at least one type of medicinal CAM in the preceding 4 weeks. The 1-year prevalence for consultation with CAM providers was 10.8%. From the drugs identified as CAM, 53.7% were homeopathic remedies, and 30.8% were herbal drugs. Factors associated with higher medicinal CAM use were female gender, residing in Munich, and higher maternal education. A homeopathy user utilized on average homeopathic remedies worth EUR 15.28. The corresponding figure for herbal drug users was EUR 16.02, and EUR 18.72 for overall medicinal CAM users. Compared with the 10-year follow-up, the prevalence of homeopathy use was more than halved (-52%) and dropped substantially for herbal drug use (-36%) and overall CAM use (-38%) as well. CONCLUSION: CAM use among 15-year-old children in the GINIplus cohort is popular, but decreased noticeably compared with children from the same cohort at the age of 10 years. This is possibly mainly because German health legislation normally covers CAM for children younger than 12 years only.

[Opinions of medical students about complementary therapies]. / Opiniones sobre terapias complementarias por parte de los estudiantes de medicina de la Pontificia Universidad Católica de Chile. Año 2014.

BACKGROUND: There is increasing national and worldwide interest on complementary therapies (CT). AIM: To describe and analyze the opinions and interest about CT among medical students. MATERIAL AND METHODS: An anonymous and voluntary survey with questions used in previous studies, was applied to students from first to fifth year. RESULTS: The survey was answered by 526 medical students, corresponding to 86% of the target population. The students knew about an average of 4.7 therapies, out of 12 displayed. The better known therapy was acupuncture, followed by homeopathy and reiki, which raised the greater interest. The knowledge and interest was higher among women, who also had a more favorable opinion about CT. The interest decreases and the proportion of unfavorable opinions increases among students of upper level courses. Forty nine percent of respondents have used CT for themselves and 22% had no experience whatsoever with them. CONCLUSIONS: In general, there is an appreciable knowledge, experience, interest and positive opinions toward CT. This favorable attitude is higher in women and decreases as career progresses. Medical students consider that they should have some approach to CT during their career.

Complementary and alternative medicine (CAM) use in an Italian cohort of pediatric headache patients: the tip of the iceberg.

The use of complementary alternative medicine (CAM) in paediatric populations is considerably increased, especially for pain and chronic conditions, as demonstrated by epidemiological surveys both in Europe and in the USA. In our study, CAM was used in 76 % patients of a cohort of 124 children affected by headache (age 4-16 years; 67 % female; 70 % migraine without aura, 12 % migraine with aura, 18 % tensive headache according to IHS criteria) consecutively recruited at a Pediatric Headache University Center. CAM was used as preventive treatment in 80 % cases. The main reasons for seeking CAM were: the wish of avoiding chronic use of drugs with their related side effects, the desire of an integrated approach, the reported inefficacy of conventional medicine, and a more suitable children disposition to CAM than to pharmacological compound. Female gender, younger age, migraine without aura, parents' higher educational status, maternal use of CAM and other associated chronic conditions, correlated with CAM use (p < 0.05). 73 % patients chose CAM also to treat other diseases (i.e. allergies, colitis, asthma, insomnia, muscle-scheletric disorders and dysmenorrhoea). The most assumed CAM were: herbal remedies (64 %) such as Valeriana, Ginkgo biloba, Boswellia serrata, Vitex agnus-castus, passion flower, Linden tree; vitamins/minerals supplements (40 %) with magnesium, 5-Hydroxytryptophan, vitamin B6 or B12, Multivitamin compounds; Homeopathy (47 %) with Silicea, Ignatia Amara, Pulsatilla, Aconitum, Nux Vomica, Calcarea phosphorica; physical treatment (45 %) such as Ayurvedic massage, shiatsu, osteopathy; yoga (33 %); acupuncture (11 %). CAM-often integrated with conventional care-was auto-prescribed in 30 % of the cases, suggested by non-physician in 22 %, by the General Practitioner in 24 % and by paediatrician in 24 %. Both general practitioners and neurologists were mostly unaware of their patients' CAM use. In conclusion, neurologists should inquire for CAM use and be prepared to learn about CAM therapies or to directly interact with CAM trained experts, in order to coordinate an integrative approach to health, as especially required in paediatric headache patients and their parents. Further studies are required to investigate safety and efficacy of CAM in pediatric headache, as a possible side-medicine to conventional pharmacological approach.

Pattern and predictors of complementary and alternative medicine (CAM) use among pediatric patients with epilepsy.

Parents of pediatric patients with chronic conditions such as epilepsy increasingly opt for complementary and alternative medicine (CAM). However, data on the pattern and reasons of CAM use in childhood epilepsy are scarce. The objectives of this study were as follows: first, to characterize CAM use among pediatric patients with epilepsy by assessing its spectrum, prevalence, costs, and frequency of use; second, to evaluate the influence of CAM use on compliance and satisfaction with conventional care as well as to explore parent-child neurologist communication concerning CAM; and third, to investigate predictors of CAM use. A postal survey was administered to all parents of pediatric outpatients with epilepsy aged 6 to 12, who have received treatment at the neuropediatric outpatient clinic of the University Children's Hospital Heidelberg between 2007 and 2009. One hundred thirty-two of the 297 distributed questionnaires were suitable for inclusion in statistical analysis (44.7%). Forty-nine participants indicated that their children used CAM during the previous year (37.1%). Thirty different types of CAM were used, with homeopathy (55.1%), osteopathy (24.5%), and kinesiology (16.3%) being the most commonly named. A mean of 86€ (0€-500€) and 3h (1 h-30 h) per month was committed to CAM treatment. Only 53% of the users informed their child neurologist of the additional CAM treatment, while 85.6% of all parents wished to discuss CAM options with their child neurologist. Seventy-five percent of users considered the CAM treatment effective. Among the participants most likely to seek CAM treatment are parents whose children show a long duration of epileptic symptoms, parents who make use of CAM treatment themselves, and parents who value a holistic and natural treatment approach. A substantial portion of pediatric patients with epilepsy receive CAM treatment. The high prevalence of use and significant level of financial and time resources spent on CAM indicate the high importance of these treatment options for parents. On the other hand, communication concerning CAM with the child neurologist is largely insufficient despite the wish to speak about CAM. Complementary and alternative medicine users' high compliance with conventional treatment and high perceived effectiveness of CAM support an integrative approach to CAM for pediatric patients with epilepsy. Our study implies that in addition to open parent-child neurologist communication, active inquiry on CAM treatments is necessary to enable informed decision making by parents and to establish the suitability of CAM treatment for the patient. Reliable predictors for CAM use, which allow for improved identification of patients with a high likelihood to receive CAM treatment, are the duration of the illness, use of CAM by the parents themselves, and the desire of the parents to receive a holistic and natural treatment for their child.

Opium could be considered an independent risk factor for lung cancer: a case-control study.

BACKGROUND: Lung cancer is the leading cause of cancer-related death worldwide, and half of all incident lung cancers are believed to occur in the developing countries, including Iran. OBJECTIVE: We investigated the association of opium with the risk of lung cancer in a case-control study. METHODS: We enrolled 242 cases and 484 matched controls in this study. A questionnaire was developed, containing questions on basic demographic characteristics, as well as lifelong history of smoking cigarettes, exposure to passive smoking, opium use and alcohol consumption. For smoking cigarettes and opium and also oral opium intake frequency, duration and cumulative use were categorized into three groups: no use, low use and high use. Conditional logistic regression was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Multivariate analysis in men showed that after adjusting for the effect of ethnicity, education and pack years of smoking cigarettes, smoking opium remained as a significant independent risk factor with an OR of 3.1 (95% CI 1.2-8.1). In addition, concomitant heavy smoking of cigarettes and opium dramatically increased the risk of lung cancer to an OR of 35.0 (95% CI 11.4-107.9). CONCLUSION: This study demonstrated that smoking opium is associated with a high risk of lung cancer as an independent risk factor.

The Manitoba Inflammatory Bowel Disease Cohort Study: a prospective longitudinal evaluation of the use of complementary and alternative medicine services and products.

OBJECTIVE: To determine the prevalence of complementary and alternative medicine (CAM) use over time in a population-based cohort of patients with inflammatory bowel disease (IBD). METHODS: The Manitoba IBD Cohort Study is a longitudinal, population-based study of multiple determinants of health outcomes in an IBD cohort. Participants completed semi-annual surveys, and annual in-person interviews. Enquiries about the use of 12 types of CAM service providers and 13 CAM products, based on items from a national survey, were included at months 0, 12, 30 and 54. RESULTS: Overall, 74% of respondents used a CAM service or product in the 4.5-year period, with approximately 40% using some type of CAM at each time point, and 14% using CAM consistently at every time point. There was a trend for women to use CAM more than men; there was no difference in CAM use between patients with Crohn's disease and those with ulcerative colitis. The most often used CAM services (on average) were massage therapy (30%) and chiropractic (14%), physiotherapy (4%), acupuncture (3.5%) and naturopathy/homeopathy (3.5%). A wide range of CAM products were used, with Lactobacillus acidophilus (8%), fish and other oils (5.5%), glucosamine (4%) and chamomile (3.5%) as the most common. On average, only 18% of consumers used CAM for their IBD, so the majority chose it for other problems. There were no differences in psychological variables between CAM users and non-users. CONCLUSIONS: Those with IBD commonly try CAM, although very few use these approaches regularly over the years. CAM is not usually used by patients with IBD for disease management, but clinicians should be aware that many will test the services and products.

Use of complementary and alternative medicine in patients with inflammatory bowel disease: results of a cross-sectional study in Norway.

OBJECTIVE: To determine the proportion of complementary and alternative medicine (CAM) use in patients with inflammatory bowel disease (IBD) and to identify demographic and clinical factors that are associated with CAM use. MATERIAL AND METHODS: In this cross-sectional study design, patients with confirmed diagnosis of ulcerative colitis (UC) or Crohn's disease (CD), and ≥18 years old, attending outpatient clinics at 14 hospitals in Norway were eligible to complete questionnaires including demographics, clinical variables, and the International CAM Questionnaire (I-CAM-Q). RESULTS: Of 460 patients included in the study, 430 had evaluable questionnaires (response rate 93%). Forty-nine percent (95% CI: 44-54) had used some type of CAM within the past 12 months. CAM services were utilized by 27% (95% CI: 23-31) of the patients, 21% (95% CI: 16-23) reported use of CAM products, and 28% (95% CI: 23-31) used CAM self-help practices. The most common pattern of CAM use was to combine CAM services and CAM products. Significantly, more UC patients (56%) than CD patients (44%) reported CAM use, p = 0.03. In UC, only the presence of at least one comorbid condition was directly related to CAM use. In CD, being a woman, being aged 31-50 years, having a higher education level, and experiencing adverse drug reactions from IBD medication were factors independently associated with the use of CAM. CONCLUSION: Use of CAM was common among IBD patients attending outpatient clinics. Both demographic and clinical factors were associated to CAM use, but the factors differed in their significance for UC and CD.

Complementary and alternative medicine in sarcoma patients treated in an Italian sarcoma center.

BACKGROUND: Bone and soft-tissue sarcoma are rare tumors. Complementary and alternative medicine (CAM) is often used in cancer patients however limited data are available in sarcoma patients. The aim of the present study is to explore the use of CAM in patients with bone and soft-tissue sarcoma. METHODS: Patients in follow-up visit for high grade bone or soft-tissue sarcoma at the Rizzoli outpatient clinic from September 1, 2014, to December 31, 2015, were asked, after written consent, to fill out a questionnaire with items pertaining to sociodemographic factors and their use of CAM before, during, or after chemotherapy. RESULTS: Four hundred and sixty-nine participated to the survey: 409 were adults and 60 were <18 years old. The percentage of use of CAM in adults was 44.7% and in minors 38.3%. The most common type of CAM was vitamins and minerals, followed by phytotherapy and homeopathy. The majority of patients used CAM after the sarcoma diagnosis. None used CAM alone instead of conventional chemotherapy. Benefits from use of CAM were reported by 75% of patients (some benefit in 53% plus high benefit in others 22%) and side effects in 6.7%. A significant correlation was found with CAM use and female gender, young age (18-44) and higher education. Disclosure to the oncologist was 56% and 69% to their family doctors. CONCLUSIONS: This study shows that CAM use is frequent among adults and pediatric patients with bone and soft tissue sarcoma as in other cancer patients. Moreover, the profile of these Italian CAM consumers in sarcoma patients is similar to other studies. Patients disclosure to their oncologist or physician about the use of CAM was similar to other Italian studies, but higher compared to other international studies.

[Therapeutic effect of Haobieyangyinruanjianfang on the mouse liver fibrosis caused by schistosomiasis].

OBJECTIVE: To explore therapeutic effect of Haobieyangyinruanjianfang (HBYYRJ) on mouse liver fibrosis by schistosomiasis. METHODS: Mice except for normal control were infected with Japanese schistosome cercarias, after 12 weeks, infected mice were divided into 7 groups: low HBYYRJ group, middle HBYYRJ group, high HBYYRJ group, Fufangbiejiaruangan tablet (FFBJRG) group, colchicine group, 3 months infection group and 6 months infection group. Hepatic fibrosis was found in 3 months infection group. Liver hydroxyproline (Hyp) was determined, matrix metalloproteinase-2 and 9 (MMP-2, MMP-9) were detected with gelatin zymography, serum hyaluronic acid (HA) and precollagen III (PC-III) were detected using RIA. RESULTS: HBYYRJ obviously reduced hepatic fibrosis (probability value less than 0.01). Collagen and HA in 3 months infection group and 6 months infection group were higher than that in normal group (probability value less than 0.01), collagen in high and middle HBYYRJ groups and HA in middle and low HBYYRJ groups were lower than that in 6 months infection group (P less than 0.01, probability value less than 0.05). The expression of MMP-9 and MMP-2 in 3 months infection group and 6 months infection group was higher than that in normal group (probability value less than 0.01), The expression of MMP-9 in three HBYYRJ groups and the expression of MMP-2 in high HBYYRJ group were lower than that in 6 months infection group (probability value less than 0.05). CONCLUSION: HBYYRJ can reduce liver fibrosis caused by schistosomiasis.

[Treatment adherence and use of complementary and alternative medicine in patients with inflammatory bowel disease]. / A terápiás adherencia, valamint a komplementer és alternatív gyógymódok használata gyulladásos bélbetegek kezelésében.

UNLABELLED: Previous studies have suggested an increasing use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). Furthermore, a significant number of IBD patients fail to comply with treatment. The aim of our study was to evaluate the prevalence of non-adherence the use of CAM in Hungarian patients with IBD. METHODS: A total of 655 consecutive IBD patients (Crohn's disease [CD]: 344, age: 38.2 + or - 12.9 years; ulcerative colitis [UC]: 311, age: 44.9 + or - 15.3 years) were interviewed during the visit at specialists by self-administered questionnaire including demographic and disease-related data, as well as items analyzing the extent of non-adherence and CAM use. Patients taking more then 80% of each prescribed medicine were classified as adherent. RESULTS: The overall rate of self reported non-adherence (CD: 20.9%, UC: 20.6%) and CAM (CD: 31.7%, UC: 30.9%) use was not different between CD and UC. The most common causes of non-adherence were: forgetfulness (47.8%), too many/unnecessary pills (39.7%), being afraid of side effects (27.9%) and too frequent dosing. Most common forms of CAM were herbal tee (47.3%), homeopathy (14.6%), special diet (12.2%), and acupuncture (5.8%). In CD, disease duration, date of last follow-up visit, educational level and previous surgeries were predicting factors for non-adherence. Alternative medicine use was associated in both diseases with younger age, higher educational level and immunosuppressant use. In addition, CAM use in UC was more common in females and in patients with supportive psychiatric/psychological therapy. CONCLUSIONS: Non-adherence and CAM use is common in patients with IBD. Special attention should be paid to explore the identified predictive factors during follow-up visits to improve adherence to therapy and improving patient-doctor relationship.

Prevalence and correlates of selected alternative and complementary medicine in adult renal transplant patients.

BACKGROUND/SIGNIFICANCE: The use of complementary and alternative medicine (CAM) has increased considerably in the general population in recent decades. However, the prevalence of CAM use in renal transplant patients has not yet been assessed. AIM: To determine the prevalence and correlates of CAM use among renal transplant patients (RTX) who are more than one year post transplant. METHODS: This secondary data analysis used data from Part 1 of the Supporting Medication Adherence in Renal Transplantation (SMART) study, which tested prevalence, determinants and consequences of non-adherence regarding immunosuppressive medication in kidney transplant (renal TX) patients. The study's convenience sample consisted of 356 patients recruited from two Swiss outpatient transplant clinics during their annual examination visits (mean age: 53+/-13; male: 58%). The use of CAM as well as the specific kind of CAM used was assessed through structured interviews. Assessed CAM use correlates were age, gender, education, depressive symptomatology, comorbidity and smoking status. Relationships between CAM use and candidate correlates were explored using multiple logistic regression. RESULTS: The prevalence of CAM use in this sample of renal TX patients was 11.8%. Most frequently used alternative medicines were Homeopathy (42.9%) and Chinese medicine (23.8%). Two patients used St John's wort. The percentage of patients using Homeopathy (5.1%) and herbal medicine (2%) was similar to that of the general Swiss population (HO: 6.1% & HM: 2.6%). Significant correlates for CAM use were younger age (p=0.017; OR=0.96; 95%CI=0.93-0.99) and female gender (p=0.035; OR=2.13; 95%CI=1.05-4.3). CONCLUSION: Every eighth renal transplant recipient in this sample used some form of CAM. Of these, some used herbal medicines, of which some are known to interfere with certain immunosuppressive treatment (St John's wort/Chinese medicines). These findings indicate that it is important for health care providers working in renal TX to assess CAM use.

Quality of life in opium-addicted patients with coronary artery disease as measured with WHOQOL-BREF.

OBJECTIVE: Several factors can influence the quality of life in patients with coronary artery disease (CAD). The goal of this research was to measure quality of life in opium-addicted patients with CAD in order to assess the effect of CAD risk factors on their quality of life. METHOD: The WHOQOL-BREF questionnaire was completed through interviews with 275 patients who underwent isolated coronary artery bypass surgery in Tehran Heart Centre between May and September 2006. RESULTS: No significant differences were found in the mean scores of the four domains of quality of life between the addicted and non-addicted patients. Furthermore, the evaluation of QOL in the groups with CAD risk factors showed that the mean QOL domains were statistically similar between opium addicted and non-opium addicted patients. In the addicted group, men had a higher psychological health score than women. A previous history of myocardial infarction reduced the psychological score in this group. Also, in the addicted patients with a history of diabetes mellitus, social functioning was better than that of the non-diabetics. CONCLUSIONS: The different domains of quality of life in our opium-addicted and non-addicted patients with CAD were similar; and among all the major risk factors for coronary artery disease, only female gender and a previous history of myocardial infarction could influence quality of life in the opium-addicted patients.

Attitudes towards vaccination: users of complementary and alternative medicine versus non-users.

PRINCIPLES: Children whose parents use complementary and alternative medicine (CAM) often show a lower rate of vaccination than those of parents favouring conventional medicine. We have investigated whether this applies to the paediatric patients presenting to an emergency department in German-speaking Switzerland, where popularity of CAM is rather high. METHODS: A cross-sectional survey was performed of paediatric patients presenting to an urban, tertiary paediatric emergency department. 1,007 (63%) of the distributed 1,600 questionnaires were available for analysis. RESULTS: 12.7% of all respondents reported refusing some basic vaccination: 3.9% because of recommendation of the physician, 8.7% despite their physician's recommendation. Socio-demographic characterisation of the group of patients refusing vaccination showed older age of children, higher proportion of girls, more single-mothers families and decreased household income. Refusal of basic vaccination was significantly more frequent among CAM-users than among non-users (18.2% versus 3.5%, p <0.001). The highest frequencies of refusal were reported by patients who consulted physicians practicing herbal medicine, anthroposophical medicine or homeopathy. Users and non-users of CAM however, showed comparable rates of immunisation in the case of the vaccinations against invasive meningococcal, pneumococcal disease and flu. Surprisingly, the rate for vaccination against tick-borne encephalitis was higher in the CAM-users group than among the non-users (21.2% versus 15.4%, p <0.05). CONCLUSIONS: A considerable proportion of the study population did not fully accept basic vaccinations. Refusal to follow the basic vaccination schemata was more frequent among CAM-users than non-users and reflected in most cases parental wishes rather than physicians' recommendations.

Prevalence in the use of complementary medicine among cancer patients in Tuscany, Italy.

AIMS AND BACKGROUND: A previous survey by Molassiotis et al. (Ann Oncol, 16: 655-663, 2005) on the use of complementary and alternative medicines (CAM) among cancer patients in Europe reported that 73% of the Italian cancer patients had used CAM, a number well above the European average of 36%. Some national variation in preference of CAM was reported, and Italian cancer patients were reported to have high use of homeopathy, herbal medicine, and spiritual therapies. The difference between CAM use in Italy and other European countries intrigued a further investigation of CAM use among Italian cancer patients. METHODS: A survey using the same questionnaire as Molassiotis et al. was conducted at two oncology day hospitals in Tuscany and included 132 patients (55% male, 45% female, with various forms of cancer) on chemotherapy. The response rate was 71%. RESULTS: The incidence of CAM use after cancer diagnosis among Tuscan cancer patients was 17%. The most widely used forms were herbal medicine (52%), homeopathy (30%) and acupuncture (13%). Use was higher in the urban area and among women, breast cancer patients, and persons with a higher education. These results agree with results of other studies on the use of CAM among Italians and Europeans in general, as well as among cancer patients in Italy. CONCLUSIONS: The high prevalence of CAM use among Italians reported by Molassiotis et al. cannot be regarded a national estimate on the use of CAM for cancer in Italy. Rather it may reflect a relatively high use of CAM in palliative care, in Northern Italy and in urban areas. CAM use among Italians in general as well as among Tuscan cancer patients in chemotherapy is modest compared with the overall European use and reflects a general high use of CAM among urbanites, women and those with a higher education. Most commonly used forms of CAM are herbal medicine and homeopathy.

Effects of a homeopathic complex in Nile tilapia (Oreochromis niloticus L.) on performance, sexual proportion and histology.

This study aimed to evaluate the effects of the homeopathic complex Homeopatila RS (REAL Homeopathy, Brazil), in the performance, sexual proportion and gills and liver histology of the Nile tilapia fish (Oreochromis niloticus L.). 4,800 post-larvae were treated for 45 days, in 12 tanks (500 L), in a closed environment, with density of 400 larvae per tank. Three treatments were given: alcohol 30%, negative control (C); hormonal, positive control, 17 alpha-methyltestosterone (H); homeopathic, Homeopatila RS, in ethanol (HH), with four replications. Mean values for length, weight, liver somatic index, condition factor, survival rate, average values of histological alterations and sexual proportion were determined. Analysis revealed significant differences (p<0.05) in growth, survival rate, liver somatic index and average values of hepatic histological alterations between treatments. It was concluded that the addition of Homeopatila RS to the diet of Nile tilapias, during the phase of gonadal differentiation, did not induce any alteration in the sexual proportion. Homeopathically treated fish were significantly smaller, but had significantly greater survival than the other two groups, there was no significant difference in final total biomass. The homeopathically treated fish had a lower liver/somatic index with less hepatic lipid inclusions than the other groups.

Complementary and alternative therapies in dentistry and characteristics of dentists who recommend them.

OBJECTIVES: The aims of this study were to analyse whether dentists offer or recommend complementary and alternative medicine (CAM) remedies in their clinical routine, and how effective these are rated by proponents and opponents. A second aim of this study was to give a profile of the dentists endorsing CAM. DESIGN: A prospective, explorative, anonymised cross-sectional survey was spread among practicing dentists in Germany via congresses, dental periodicals and online (n=250, 55% male, 45% female; mean age 49.1±11.4years). RESULTS: Of a set of 31 predefined CAM modalities, the dentists integrated plant extracts from Arnica montana (64%), chamomile (64%), clove (63%), Salvia officinalis (54%), but also relaxation therapies (62%), homeopathy (57%), osteopathic medicine (50%) and dietetics (50%). The effectiveness of specific treatments was rated significantly higher (p<0.0001) by CAM proponents than opponents. However also CAM opponents classified some CAM remedies as highly effective, namely ear acupuncture, osteopathic medicine and clove. For ear acupuncture these scores did not significantly differ between both groups. With respect to the characteristic of the proponents, the majority of CAM endorsing dentists were women. The mean age (50.4±0.9 vs 47.0±0.9years) and number of years of professional experience (24.2±1.0 vs 20.0±1.0years) were significantly higher for CAM proponents than the means for opponents (p<0.0001 respectively). CAM proponents worked significantly less (p<0.0001) and their perceived workload was significantly lower (p=0.008). Their self-efficacy expectation (SEE) and work engagement (Utrecht work engagement, UWE) were significantly higher (p≤0.01 and p<0.0001) compared to dentists who abandoned these treatment options. The logistic regression model showed (exploratively) an increased association from CAM proponents with the UWES subscale dedication, with years of experience, and that men are less likely to be CAM proponents than women. CONCLUSION: Various CAM treatments are recommended by German dentists and requested by their patients, but the scientific evidence for these treatments are often low or at least unclear. CAM proponents are often female, have higher SE and work engagement.
