Vitamin D supplementation for nonspecific musculoskeletal pain in non-Western immigrants: a randomized controlled trial.

PURPOSE: Many non-Western immigrants report musculoskeletal pains that are hard to treat. We studied the effect of high-dose vitamin D(3) on nonspecific persistent musculoskeletal complaints in vitamin D-deficient non-Western immigrants and assessed correlation of pain patterns with benefit. METHODS: We conducted a semi-crossover randomized controlled trial between February 2008 and February 2010 in primary care in 84 non-Western immigrants visiting their general practitioner for nonspecific musculoskeletal pain. At baseline, patients were randomized to placebo or vitamin D (150,000 IU vitamin D(3) orally); at week 6, patients in the original vitamin D group were randomized a second time to receive vitamin D (again) or to switch to placebo, whereas patients in the original placebo group were all switched to vitamin D. The main outcome was self-assessed change in pain after the first 6 weeks. RESULTS: Patients in the vitamin D group were significantly more likely than their counterparts in the placebo group to report pain relief 6 weeks after treatment (34.9% vs 19.5%, P = .04). The former were also more likely to report an improved ability to walk stairs (21.0% vs 8.4%, P = .008). Pain pattern was not correlated with the success of treatment. In a nonsignificant trend, patients receiving vitamin D over 12 weeks were more likely to have an improvement than patients receiving it over 6 weeks. CONCLUSIONS: There is a small positive effect 6 weeks after high-dose vitamin D(3) on persistent nonspecific musculoskeletal pain. Future research should focus on longer follow-up, higher supplementation doses, and mental health.

Muslim women's physician preference: beyond obstetrics and gynecology.

When Emirati (Muslim) women (n = 218) were asked about their preferred physician (in terms of gender, religion, and nationality) for three personal clinical scenarios, a female was almost exclusively preferred for the gynecological (96.8%) and "stomach" (94.5%) scenarios, while ±46% of the women also preferred a female physician for the facial allergy scenario. Only 17% considered physician gender important for the prepubertal child scenario. Just over half of the women preferred a Muslim physician for personal examinations (vs. 37.6% for the child). Being less educated and having a lower literacy level were significant predictors of preferred physician religion for some personal scenarios, whereas a higher education level was a significant predictor for physician gender not mattering for the facial allergy scenario. Muslim women's preference for same gender physicians, and to a lesser extent religion, has implications for health care services beyond obstetrics and gynecology.

Allergic rhinitis and asthma: a large cross-sectional study in the United Arab Emirates.

BACKGROUND: Studies on comorbidity of allergic rhinitis (AR) and asthma have been carried out in developed countries; however, data from countries in development transition are lacking. METHODS: In a randomly selected, age-stratified cohort of adolescent school children and their caretakers in the United Arab Emirates (UAE), comorbidity of AR and asthma was calculated using multinomial regression to determine independent risk factors. RESULTS: A total of 6,543 subjects were included in the study; the median age was 30 years (range 8-93), and 52% were males. The standardized prevalence of concomitant asthma and AR was 7.3%. AR subjects had a 3-fold increased risk of asthma compared to subjects without AR (23.8 and 7.5%, respectively). Immigrants had a significantly lower prevalence of comorbidity of AR and asthma [adjusted odds ratio (OR) 0.53, 95% confidence interval (CI) 0.33-0.85] compared to UAE nationals, while greater age carried a lower risk (adjusted OR 0.58, 95% CI 0.44-0.78), but a family history of both AR (adjusted OR 3.03, 95% CI 2.31-3.98) and asthma (adjusted OR 4.65, 95% CI 3.53-6.12) was strongly associated with the co-occurrence of these 2 conditions, while gender and education were not. Asthma patients with AR had more severe symptoms than those without, i.e. 'dry cough at night' in 65 versus 36%, ß-mimeticum use in 42 versus 30%, and steroid use in 25 versus 13%, respectively. CONCLUSION: Comorbidity of asthma and AR in the UAE is high, with a prevalence of 7.3%. Both the underlying reasons and possibilities for better prevention now need to be focused on in future research.

Muslim women and medical students in the clinical encounter.

CONTEXT: Increasingly, male medical students report being refused by female patients, particularly in obstetrics and gynaecology, which is impacting on recruitment into the discipline. However, little has been documented in terms of Muslim patients and medical students in the clinical consultation. METHODS: Female Emirati nationals (n = 218) attending out-patient clinics at a public hospital in Al Ain, United Arab Emirates (UAE), were interviewed by medical students. Participants were provided with four hypothetical clinical scenarios (three personal, one concerning a pre-pubertal child) and asked whether they would allow male and female students to be present at a consultation, take a history or perform an examination. They were also canvassed about their past experiences with medical students and their social responsibility to contribute towards the training of Emirati doctors. RESULTS: Significant differences were recorded in terms of female versus male student involvement for all activities (P < 0.05-0.0005). For gynaecological and abdominal problems, patients would generally refuse male students. More than 50% of interviewees would not allow a male student to examine their face. Students of either gender could, however, examine their 8-year-old child. Although 47% of the women had had previous clinical encounters with students, in only 58% of consultations had the attending doctor asked their permission. Despite this, the women had generally felt comfortable, although satisfaction decreased with increasing age (P = 0.088). Almost 90% of the women believed that Emiratis had a social responsibility to contribute towards the training of Emirati doctors, but this decreased with increasing income (P = 0.004). CONCLUSIONS: As many medical students will encounter Muslim patients during their training, they need to be sensitive to religious and cultural issues, particularly for personal examinations. In contexts where most patients are Muslim, alternative options (e.g. manikins, international rotations) may be required for male students. In the UAE, patient education may improve history-taking opportunities but will probably not transcend religious and cultural beliefs without intervention from religious leaders.

Prevalence and risk factors of asthma among adolescents and their parents in Al-Ain (United Arab Emirates).

BACKGROUND: Evidence indicates that the prevalence of asthma tends to increase in the developed world. However, little is known about current prevalence rates and risk factors of asthma in countries in transition, e.g. the United Arab Emirates (UAE). OBJECTIVES: We investigated the prevalence of asthma and its independent risk factors among adolescents and adults in Al-Ain, UAE. METHODS: For a two-stage, randomly selected survey, 10,000 questionnaires were distributed to adolescents and their parents. Logistic regression was applied to assess asthma prevalence and independent associations with age, gender, education, nationality and family history. RESULTS: In total, 6,543 subjects were included in the final analysis. Median age was 30 years (range: 8-93 years); 53% were male. The overall self-reported prevalence of asthma was 13%. Direct standardization with the UAE population as the reference yielded a prevalence of 12%. Logistic regression revealed family history and UAE nationality (about 50% of nationals were of Bedouin origin) as the main risk factors for asthma, and a significant (p = 0.001) interaction between gender and age: in the group aged 13-19 years, males had a significantly higher prevalence of asthma [17 and 14%; adjusted odds ratio (OR): 1.45; 95% confidence interval (CI): 1.10-1.90]; in the group aged >19 years, males had a significantly lower prevalence of asthma (11 and 13%; adjusted OR: 0.77; 95% CI: 0.60-0.95) than females. CONCLUSIONS: The prevalence of asthma is comparable to findings of earlier studies. The higher prevalence in adolescent males compared to females may possibly be due to sex-specific lifestyle factors. Strong predictors of asthma such as family history and UAE nationality may indicate modernization and possible genetic susceptibility, warranting further studies in this population.

Prospective evaluation of mannan and anti-mannan antibodies for diagnosis of invasive Candida infections in patients with neutropenic fever.

The diagnostic performance and usefulness of the Platelia antigen and antibody test (Bio-Rad) was investigated in a prospective study of haematological patients at risk for invasive Candida infections. Among 100 patients, 86 were eligible, of whom invasive candidiasis (IC) occurred in 12 (14%), according to the criteria of the European Organization for Research and Treatment of Cancer/Mycoses Study Group. These included candidaemia due to Candida albicans (one patient) or Candida tropicalis (four patients), and hepatosplenic candidiasis (seven patients). The comparator group of 74 patients included 50 with febrile neutropenia alone and 24 with mould infections. A strategy was developed to determine diagnostic cut-offs from receiver operating characteristic curves with maximal sensitivity and, given this sensitivity, maximal specificity, both being greater than 0. In this patient population, these values were 0.25 ng ml(-1) for mannan (M) and 2.6 arbitrary units ml(-1) for anti-mannan (AM), which are lower than those recommended by the manufacturer. All patients developed at least one positive diagnostic M or AM result during the 10 days of persistent febrile neutropenia (PFN). The optimal overall performance was found when two consecutive positive tests for both M and AM were used [sensitivity, specificity, positive predictive value and negative predictive value (NPV) (95 % confidence intervals) of 0.73 (0.39-0.94), 0.80 (0.69-0.89), 0.36 (0.17-0.59) and 0.95 (0.86-0.99), respectively]. There was a positive correlation of M with beta-D-glucan (r=0.28, P=0.01). The first positive M test was found up to a mean+/-sd of 8.8+/-8.5 (range 2-23) days prior to a clinical/mycological diagnosis of IC. Day-to-day variation in quantitative M levels was high. High-level AM responses were delayed until leucopenia resolved. The low specificities of the test performance may have been due to some of the comparator patients having subclinical Candida infections as evidenced by the high incidence of colonization among them (60% had a colonization index of >or=0.5). The high NPVs suggest that the tests may be particularly useful in excluding IC. It is feasible to explore the use of serial measurements of M and AM as part of a broader diagnostic strategy for selecting PFN patients to receive antifungal drug therapy.

Management decisions in nontraumatic complaints of arm, neck, and shoulder in general practice.

UNLABELLED: OBJECTIVE We wanted to evaluate associations between diagnosis and characteristics of the patient, complaint, and general practitioner (GP), as well as 6 common management decisions, in patients with nontraumatic arm, neck, and shoulder complaints at the time of the first consultation with their physician. METHODS: We undertook an observational cohort study set in 21 Dutch general practices, including 682 patients with nontraumatic complaints of arm, neck, and shoulder. The outcome measure was application (yes/no) of a specific management option: watchful waiting, additional diagnostic tests, prescription of medication, corticosteroid injection, referral for physiotherapy, and referral for medical specialist care. RESULTS: Separate multilevel analyses showed that overall, the diagnostic category, having long duration of complaints, and reporting many functional limitations were most frequently associated with the choice of a management option. For watchful waiting, only complaint variables played a role (long duration of complaints, high complaint severity, many functional limitations, recurrent complaint). All these variables were negatively associated with watchful waiting. When opting for 1 of the 5 other management options, several physician characteristics played a role as well. Less clinical experience was associated with additional diagnostic tests and referral to a medical specialist. GPs working in a solo practice more frequently referred to a medical specialist. GPs working in a rural area more frequently referred for physiotherapy. Female GPs prescribed medication less frequently. Physicians with special interest in musculoskeletal complaints gave corticosteroid injections more frequently. CONCLUSIONS: Diagnostic category, long duration of complaints, and high functional limitations were key variables in management decisions with these complaints. In addition, several physician characteristics played a role as well.

Measles, mumps and rubella infections and atopic disorders in MMR-unvaccinated and MMR-vaccinated children.

Vaccinations have been incriminated in the increase of atopic disorders. Especially the measles-mumps-rubella (MMR) vaccination is often refused by people having a notion that these infectious diseases are beneficial for a healthy development of a child's immune system. This practice endangers herd immunity and is the cause of repeated outbreaks. As the clinical course of infections and also its possible impact on the development of atopy may be different in vaccinated and unvaccinated individuals, we explored in vaccinated and unvaccinated children associations of MMR infection with atopic disorders. Using data from a previously conducted study on the relationship between the diphtheria-tetanus-pertussis-(inactivated) poliomyelitis vaccination in the first year of life and atopic disorders, the study population of 1872 8-12-yr-old was divided as children MMR-unvaccinated and children MMR-vaccinated in the first year of life. Within each group the association between MMR infections and atopic disorders (both as reported by the parents) was assessed. We found a statistically significant positive association between measles infection and 'any atopic disorder' [adjusted odds ratio, OR (95% confidence interval, CI): 1.77 (1.20-2.61)] in the MMR-vaccinated group, mainly because of the relationship with eczema. For rubella there was a negative association with eczema and food allergy in the unvaccinated group: adjusted OR (95% CI): 0.57 (0.38-0.85) and 0.23 (0.07-0.76), respectively. All other associations were not statistically significant. We found a positive relationship between measles infection and any atopy in a group of MMR-vaccinated children and a negative association between rubella infection and eczema and food allergy in unvaccinated children. However, we cannot conclude that these relationships are causal. The negative association with rubella may be an artefact. This study shows no evidence for any protective effects from MMR diseases for the development of atopy and therefore supports conclusions found elsewhere that childhood vaccinations do not cause atopy.

Inhaled sodium cromoglycate for asthma in children.

BACKGROUND: Sodium cromoglycate has been recommended as maintenance treatment for childhood asthma for many years. Its use has decreased since 1990, when inhaled corticosteroids became popular, but it is still used in many countries. OBJECTIVES: To determine the efficacy of sodium cromoglycate compared to placebo in the prophylactic treatment of children with asthma. SEARCH STRATEGY: We searched the Cochrane Airways Group Trials Register (October 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2007), MEDLINE (January 1966 to November 2007), EMBASE (January 1985 to November 2007) and reference lists of articles. We also contacted the pharmaceutical company manufacturing sodium cromoglycate. In 2007 we updated the review. SELECTION CRITERIA: All double-blind, placebo-controlled randomised trials, which addressed the effectiveness of inhaled sodium cromoglycate as maintenance therapy, studying children aged 0 up to 18 years with asthma. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. We pooled study results. MAIN RESULTS: Of 3500 titles retrieved from the literature, 24 papers reporting on 23 studies could be included in the review. The studies were published between 1970 and 1997 and together included 1026 participants. Most were cross-over studies. Few studies provided sufficient information to judge the concealment of allocation. Four studies provided results for the percentage of symptom-free days. Pooling the results did not reveal a statistically significant difference between sodium cromoglycate and placebo. For the other pooled outcomes, most of the symptom-related outcomes and bronchodilator use showed statistically significant results, but treatment effects were small. Considering the confidence intervals of the outcome measures, a clinically relevant effect of sodium cromoglycate cannot be excluded. The funnel plot showed an under-representation of small studies with negative results, suggesting publication bias. AUTHORS' CONCLUSIONS: There is insufficient evidence to be sure about the efficacy of sodium cromoglycate over placebo. Publication bias is likely to have overestimated the beneficial effects of sodium cromoglycate as maintenance therapy in childhood asthma.

Combined sensory impairment (deaf-blindness) in five percent of adults with intellectual disabilities.

Our purpose in this cross-sectional study with 1,598 adult clients who had intellectual disabilities was to obtain valid prevalences of sensory impairments and to identify associations. The diagnoses were made through ophthalmologic and audiometric assessments, applying WHO/IASSID definitions. Re-weighted prevalences were 5.0% (95% CI 3.9- 6.2%) for the total adult population; 2.9% (1.9-4.1), less than 50 years; and 11.0% (7.9- 14.7), 50 years and over. Apart from being 50 years of age and over, p = .000, risk factors were more severe intellectual disability, p = .0001, and Down syndrome, p = .001. Results show that the risk of combined sensory impairment in this population is considerably increased compared with the general population. Part of the underlying conditions are treatable or can be rehabilitated. However, the complete diagnosis had been identified in only 12%.

MRI follow-up of posttraumatic bone bruises of the knee in general practice.

OBJECTIVE: Our purpose was to study the natural course of bone bruises in posttraumatic knees and to describe possible determinants of this course. SUBJECTS AND METHODS: Prospective MRI follow-up data were gathered for patients with bone bruises after sustained knee trauma. Follow-up ceased when the bone bruise could no longer be discerned or after 1 year of follow-up. For each patient we studied the relationships between time to healing of all bone bruises and the explanatory variables age, sex, obesity, workload, sports load, number of bone bruises, osteoarthritis, and concomitant knee lesions using survival analyses. We also investigated the relationships between resolution of individual bone bruises and lesion type, size and location, and the explanatory variables at 6 months and at 12 months separately, using logistic regression analyses for repeated measurements and generalized estimating equations. RESULTS: In 80 patients, 157 bone bruises were found. The estimated median healing time was 42.1 weeks. Healing was prolonged in patients having a higher number of bone bruises and in the presence of osteoarthritis. Resolution of individual bone bruises was prolonged in the presence of osteoarthritis and greater age. Reticular lesions were less likely to be present after 6 months than other bone bruise types. None of the remaining tested variables had prognostic value. CONCLUSION: Median healing time of bone bruises is 42.1 weeks. Prognosis is particularly influenced by the presence of osteoarthritis. Age, type of bone bruise, and number of bruises also have prognostic value.

Supervised exercises for adults with acute lateral ankle sprain: a randomised controlled trial.

BACKGROUND: During the recovery period after acute ankle sprain, it is unclear whether conventional treatment should be supported by supervised exercise. AIM: To evaluate the short- and long-term effectiveness of conventional treatment combined with supervised exercises compared with conventional treatment alone in patients with an acute ankle sprain. DESIGN: Randomised controlled clinical trial. SETTING: A total of 32 Dutch general practices and the hospital emergency department. METHOD: Adults with an acute lateral ankle sprain consulting general practices or the hospital emergency department were allocated to either conventional treatment combined with supervised exercises or conventional treatment alone. Primary outcomes were subjective recovery (0-10 point scale) and the occurrence of a resprain. Measurements were carried out at intake, 4 weeks, 8 weeks, 3 months, and 1 year after injury. Data were analysed using intention-to-treat analyses. RESULTS: A total of 102 patients were enrolled and randomised to either conventional treatment alone or conventional treatment combined with supervised exercise. There was no significant difference between treatment groups concerning subjective recovery or occurrence of resprains after 3 months and 1-year of follow-up. CONCLUSION: Conventional treatment combined with supervised exercises compared to conventional treatment alone during the first year after an acute lateral ankle sprain does not lead to differences in the occurrence of resprains or in subjective recovery.

Clinical consequences of posttraumatic bone bruise in the knee.

BACKGROUND: Bone bruise is often seen in posttraumatic knees, but the clinical relevance is unclear. HYPOTHESIS: The presence of bone bruise is associated with increased pain severity in patients with sustained knee trauma. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: We collected prospective data of 132 patients visiting their general practitioner after sustained knee trauma. Patients with bone bruise underwent a magnetic resonance imaging follow-up study that was discontinued when the bone bruise could no longer be discerned or after 1 year of follow-up. Bone bruise was assessed on magnetic resonance imaging, and pain severity was scored on a numeric rating scale (0-10) at baseline, and at 3, 6, and 12 months after trauma. The presence of bone bruise and pain severity (over time) were compared using linear regression analyses for repeated measurements. Adjustment was made for possible confounders: presence of meniscal tears, cruciate or collateral ligament ruptures, severe effusion, osteoarthritis, obesity, age, gender, work load, and sports load. RESULTS: At baseline as well as during follow-up, bone bruise was associated with a slightly higher pain score. The differences, however, were very small (adjusted difference in pain severity 0.34 or less) and not statistically significant nor clinically relevant. CONCLUSION: There is no statistically significant relationship, nor a clinically relevant relationship, between the presence of bone bruise and pain severity in patients with sustained knee injury in general practice.

Kinesiophobia in patients with non-traumatic arm, neck and shoulder complaints: a prospective cohort study in general practice.

BACKGROUND: Complaints of arm, neck and shoulder are common in Western societies. Of those consulting a general practitioner (GP) with non-traumatic arm, neck or shoulder complaints, about 50% do not recover within 6 months. Kinesiophobia (also known as fear of movement/(re)injury) may also play a role in these complaints, as it may lead to avoidance behaviour resulting in hypervigilance to bodily sensations, followed by disability, disuse and depression. However, in relation to arm, neck and shoulder complaints little is known about kinesiophobia and its associated variables. Therefore this study aimed to: describe the degree of kinesiophobia in patients with non-traumatic complaints of arm, neck and shoulder in general practice; to determine whether mean scores of kinesiophobia change over time in non-recovered patients; and to evaluate variables associated with kinesiophobia at baseline. METHODS: In this prospective cohort study set in general practice, consulters with a first or new episode of non-traumatic arm, neck or shoulder complaints (aged 18-64 years) entered the cohort. Baseline data were collected on kinesiophobia using the Tampa Scale for Kinesiophobia, the 13-item adjusted version: TSK-AV, and on patient-, complaint-, and psychosocial variables using self-administered questionnaires. The mean TSK-AV score was calculated. In non-recovered patients the follow-up TSK-AV scores at 6 and 12 months were analyzed with the general linear mixed model. Variables associated with kinesiophobia at baseline were evaluated using multivariate linear regression analyses. RESULTS: The mean TSK-AV score at baseline was 24.8 [SD: 6.2]. Among non-recovered patients the mean TSK-AV score at baseline was 26.1 [SD: 6.6], which remained unchanged over 12- months follow-up period. The strongest associations with kinesiophobia were catastrophizing, disability, and comorbidity of musculoskeletal complaints. Additionally, having a shoulder complaint, low social support, high somatization and high distress contributed to the kinesiophobia score. CONCLUSION: The mean TSK-AV score in our population seems comparable to those in other populations in primary care. In patients who did not recover during the 12- month follow-up, the degree of kinesiophobia remained unchanged during this time period. The variables associated with kinesiophobia at baseline appear to be in line with the fear-avoidance model.

Haemophilus influenzae type b vaccination and reported atopic disorders in 8-12-year-old children.

Because Haemophilus influenzae type b (Hib) vaccination was added recently to most vaccination programs, no conclusive data on the relationship with atopic disorders are yet available. We sought to assess the risk of atopic disorders at ages 8-12 years associated with Hib vaccination in the first year of life, in addition to diphtheria-tetanus-pertussis-inactivated poliomyelitis vaccination (DTP-IPV) and other childhood vaccinations. Parents of 1,201 children attending Orthodox Reformed (Protestant) primary schools in The Netherlands returned questionnaires reporting data on vaccination status, atopic symptoms and physician-diagnosed lifetime atopic disorders (asthma, hay fever, eczema, and food allergy), and possible confounders. This study was conducted within the framework of a larger study on the relationship between the DTP-IPV and reported atopic disorders. The adjusted odds ratio of any atopic disorder (Hib-vaccinated/unvaccinated) was 1.09 (95% confidence interval (CI), 0.79-1.50). For asthma, hay fever, eczema, and food allergy, the results were, respectively, 0.89 (95% CI, 0.55-1.43), 0.94 (95% CI, 0.47-1.90), 1.09 (95% CI, 0.75-1.58), and 0.68 (95% CI, 0.38-1.19). In conclusion, in the Dutch population, there is no indication for a higher risk of reported physician-diagnosed atopic disorders at primary schools age after Hib vaccination in the first year of life, in addition to other vaccinations.

Do Dutch doctors communicate differently with immigrant patients than with Dutch patients?

The aim of this study was to gain deeper insight into relational aspects of the medical communication pattern in intercultural consultations at GP practices in the Netherlands. We ask whether there are differences in the verbal interaction of Dutch GPs with immigrant and Dutch patients. Data were drawn from 144 adult patient interviews and video observations of consultations between the patients and 31 Dutch GPs. The patient group consisted of 61 non-Western immigrants (Turkish, Moroccan, Surinamese, Antillean, Cape Verdian) and 83 Dutch participants. Affective and instrumental aspects of verbal communication were assessed using Roter's Interaction Analysis System (RIAS). Patients' cultural background was assessed by ethnicity, language proficiency, level of education, religiosity and cultural views (in terms of being more traditional or more modern). Consultations with the non-Western immigrant patients (especially those from Turkey and Morocco) were well over 2 min shorter, and the power distance between GPs and these patients was greater when compared to the Dutch patients. Major differences in verbal interaction were observed on the affective behavior dimensions, but not on the instrumental dimensions. Doctors invested more in trying to understand the immigrant patients, while in the case of Dutch patients they showed more involvement and empathy. Dutch patients seemed to be more assertive in the medical conversation. The differences are discussed in terms of patients' ethnic background, cultural views (e.g. practicing a religion) and linguistic barriers. It is concluded that attention to cultural diversity does matter, as this leads to different medical communication patterns. A two-way strategy is recommended for improving medical communication, with implications for both doctor and patient behavior.

Body mass index, sexual behaviour, and sexually transmitted infections: an analysis using the NHANES 1999-2000 data.

BACKGROUND: Factors determining human sexual behaviour are not completely understood, but are important in the context of sexually transmitted disease epidemiology and prevention. Being obese is commonly associated with a reduced physical attractiveness but the associations between body mass index, sexual behaviour and the risk of acquiring sexually transmitted infections has never been studied. METHODS: The National Health and Nutrition Examination Survey (NHANES) files of 1999-2000 were used. Linear regression was used to relate the reported number of sex partners in the last year and lifetime to Body Mass Index (BMI). Logistic regression was used to relate Herpes Simplex Virus type II (HSV-2) antibodies to BMI and other variables. RESULTS: Data on 979 men and 1250 women were available for analysis. Obese (mean number of partners for men:1.12, women: 0.93) and overweight (mean for men: 1.38, women: 1.03) individuals reported fewer partners than individuals of normal BMI (mean for men: 2.00, women: 1.15) in the last year (p < .0.01 & p < 0.05 for men, p < 0.05 & n.s. for women). The same relationship held for lifetime partners in men (mean 11.94, 18.80, and 22.08 for obese, overweight and normal BMI respectively (p < 0.05 & n.s. for obese and overweight vs normal respectively), but not in women (mean 7.96, 4.77, and 5.24 respectively). HSV-2 antibodies were significantly correlated with the number of lifetime partners in both men and women, with the odds of being HSV-2 positive increasing by 0.6% (p < 0.01) and 2.7% (p < 0.01) for men and women respectively. HSV-2 antibodies increased with age, even after adjustment for lifetime partners (p < 0.01). Being obese (HSV-2 prevalence 15.9 and 34.9% for men and women respectively) or overweight (HSV-2 prevalence 16.7 and 29.3 for men and women respectively) was not associated with HSV-2 antibodies (HSV-2 prevalence for normal BMI: 15.6 and 23.2% respectively), independent of whether the association was adjusted for life time sexual partners or not. There was evidence of substantial misreporting of sexual behaviour. CONCLUSION: Obese and overweight individuals, especially men, self report fewer sex partners than individuals of normal weight, but surprisingly this is not reflected in their risk of HSV-2 infection. HSV-2 antibodies provide information not contained in self-reported number of partners and may better estimate sexual risk than self-reported behaviour.

Association between skin diseases and severe bacterial infections in children: case-control study.

BACKGROUND: Sepsis or bacteraemia, however rare, is a significant cause of high mortality and serious complications in children. In previous studies skin disease or skin infections were reported as risk factor. We hypothesize that children with sepsis or bacteraemia more often presented with skin diseases to the general practitioner (GP) than other children. If our hypothesis is true the GP could reduce the risk of sepsis or bacteraemia by managing skin diseases appropriately. METHODS: We performed a case-control study using data of children aged 0-17 years of the second Dutch national survey of general practice (2001) and the National Medical Registration of all hospital admissions in the Netherlands. Cases were defined as children who were hospitalized for sepsis or bacteraemia. We selected two control groups by matching each case with six controls. The first control group was randomly selected from the GP patient lists irrespective of hospital admission and GP consultation. The second control group was randomly sampled from those children who were hospitalized for other reasons than sepsis or bacteraemia. We calculated odds ratios and 95% confidence intervals (CI). A two-sided p-value less than 0.05 was considered significant in all tests. RESULTS: We found odds ratios for skin related GP consultations of 3.4 (95% CI: [1.1-10.8], p = 0.03) in cases versus GP controls and 1.4 (95% CI: [0.5-3.9], p = 0.44) in cases versus hospital controls. Children younger than three months had an odds ratio (cases/GP controls) of 9.2 (95% CI: [0.81-106.1], p = 0.07) and 4.0 (95% CI: [0.67-23.9], p = 0.12) among cases versus hospital controls. Although cases consulted the GP more often with skin diseases than their controls, the probability of a GP consultation for skin disease was only 5% among cases. CONCLUSION: There is evidence that children who were admitted due to sepsis or bacteraemia consulted the GP more often for skin diseases than other children, but the differences are not clinically relevant indicating that there is little opportunity for GPs to reduce the risk of sepsis and/or bacteraemia considerably by managing skin diseases appropriately.

The effect of educational intervention on intercultural communication: results of a randomised controlled trial.

BACKGROUND: Due to worldwide migration to Western countries, physicians are increasingly encountering patients with different ethnic backgrounds. Communication problems can arise as a result of differences in cultural backgrounds and poor language proficiency. AIMS: To assess the effectiveness of an educational intervention on intercultural communication aimed to decrease inequalities in care provided between Western and non-Western patients. DESIGN OF STUDY: A randomised controlled trial with randomisation at the GP level and outcome measurements at the patient level. SETTING: General practice in Rotterdam. METHOD: Thirty-eight Dutch GPs in the Rotterdam region, with at least 25% of inhabitants of non-Western origin, and 2407 visiting patients were invited to participate in the study. A total of 986 consultations were finally included. The GPs were educated about cultural differences and trained in intercultural communication. Patients received a videotaped instruction focusing on how to communicate with their GP in a direct way. The primary outcome measure was mutual understanding and the secondary outcomes were patient's satisfaction and perceived quality of care. The intervention effect was assessed for all patients together, for the 'Western' and 'non-Western' patients, and for patients with different cultural backgrounds separately. RESULTS: An intervention effect was seen 6 months after the intervention, as improvement in mutual understanding (and some improvement in perceived quality of care) in consultations with 'non-Western' patients. CONCLUSIONS: A double intervention on intercultural communication given to both physician and patient decreases the gap in quality of care between 'Western' and 'non-Western' patients.
