BACKGROUND: Chronic pain disorder is assumed to represent a frequent and disabling condition. However, data on the prevalence of somatoform pain symptoms and somatoform pain disorder in the community are limited to date. METHODS: German versions of the Composite International Diagnostic Interview were administered to a representative national sample of 4,075 people. Somatoform pain disorder was diagnosed by standardized diagnostic algorithm based on the DSM-III-R criteria (absence of adequate physical findings). One subgroup was identified as also meeting the DSM-IV criterion B for 'significant distress or psychosocial impairment due to the somatoform pain'. RESULTS: A lifetime prevalence rate of somatoform pain disorder according to DSM-III-R of 33.7% and a 6-month rate of 17.3% was found. When applying the DSM-IV B criterion, the prevalence rate dropped to 12.3 and 5.4%, respectively. In both groups more than 95% of the probands had contacted their doctor because of the pain. In 25% of the probands the pain was positively assigned to psychological factors. A female:male ratio of 2:1 was found. CONCLUSIONS: Somatoform pain disorder (DSM-III-R) is a frequent condition. However, only about one third of these subjects is severely distressed or impaired by the pain. A clear operationalized concept of the DSM-IV criterion C 'psychological factors are judged to have an important role in the onset, severity, exacerbation or maintenance of the pain' should be provided in the further development of the diagnosis 'pain disorder' in order to make this diagnosis suitable for general population surveys. 相似文献

The general hospital would be especially suited to initiate interventions if hospitalized alcohol-dependent individuals were particularly motivated to change their drinking behavior. This study compares the readiness to change of alcohol-dependent persons in the general hospital and the general population. Stages of change according to the model of Prochaska and DiClemente [6] are assessed using the Readiness to Change Questionnaire (RCQ) in two representative samples: 118 alcohol-dependent subjects admitted to a general hospital (sample 1) and 50 alcohol-dependent individuals in the general population (sample 2). In sample 1, alcohol-dependent persons were identified in 1167 consecutive admissions using screening questionnaires and a diagnostic interview (SCAN). In sample 2, alcohol dependence was assessed in 4075 individuals using a German version of CIDI. The distribution of stages of change differed significantly (p < 0.0001) between the groups, revealing a shift towards higher stages in the hospital subjects. Logistic regression analysis revealed that the stages of readiness to change and age contributed in predicting whether subjects belonged to the general hospital or the general population sample. Findings suggest that the general hospital is a suitable site to initiate interventions for alcohol-dependent individuals. 相似文献

This paper provides up to date prevalence estimates of mental disorders in Germany derived from a national survey (German Health Interview and Examination Survey for Adults, Mental Health Module [DEGS1‐MH]). A nationally representative sample (N = 5318) of the adult (18–79) population was examined by clinically trained interviewers with a modified version of the Composite International Diagnostic Interview (DEGS‐CIDI) to assess symptoms, syndromes and diagnoses according to DSM‐IV‐TR (25 diagnoses covered). Of the participants 27.7% met criteria for at least one mental disorder during the past 12 months, among them 44% with more than one disorder and 22% with three or more diagnoses. Most frequent were anxiety (15.3%), mood (9.3%) and substance use disorders (5.7%). Overall rates for mental disorders were substantially higher in women (33% versus 22% in men), younger age group (18–34: 37% versus 20% in age group 65–79), when living without a partner (37% versus 26% with partnership) or with low (38%) versus high socio‐economic status (22%). High degree of urbanization (> 500,000 inhabitants versus < 20,000) was associated with elevated rates of psychotic (5.2% versus 2.5%) and mood disorders (13.9% versus 7.8%). The findings confirm that almost one third of the general population is affected by mental disorders and inform about subsets in the population who are particularly affected.

Camptothecins demonstrate a broad spectrum of antitumor activity. Although they are known to trap DNA topoisomerase I on DNA, form cleavable complexes, and generate DNA breaks upon collision with DNA or RNA polymerases, the precise mechanisms predictive for antitumor activity remain to be identified. Recent studies using panels of colorectal and breast cancer cell lines indicate that events downstream of cleavable complexes are more relevant. In this study, we chose SN-38, an active metabolite of irinotecan, to characterize DNA double strand breaks and repair mechanisms induced by this type of drugs using a human head and neck squamous cell carcinoma cell line A253. The results showed that 2-h exposure of cells to an IC(50) concentration of SN-38 induces biphasic DNA double-strand break (DSBs): an immediate phase, which was greatly reduced within 8 h, and a lagging phase, culminating 24 h after drug removal. Three DNA double-strand break repair protein complexes were activated: DNA-dependent protein kinase (DNA-PK), NBS1-MRE11-RAD50, and BRCA1. Aphidicolin, a DNA polymerase inhibitor, abolished both phase I DSBs and the activation of repair protein complexes, suggesting that they resulted from the collision between the cleavable complex and DNA polymerase of S-phase cells. This is in contrast to ionizing radiation-induced activation of DNA-PK and NBS1-MRE11-RAD50 complexes that occur predominantly among non-S-phase cells. The trigger for phase II DSBs cannot be abolished by aphidicolin. The data also indicate that DNA fragments in the size of 50 to 200 kilobases were detected in the lagging phase. This suggests that the late DNA DSBs were associated with apoptotic cell death. 相似文献

Lobaplatin [1,2-diamminomethylcyclobutane-platinum(II) lactate] is a new platinum compound with interesting preclinical activity and apparently no nephro- or neurotoxicity that is currently undergoing clinical phase II studies. Little is known about the cross-resistance between cisplatin and lobaplatin. The activity of this new compound in comparison with cisplatin and carboplatin was evaluated in cisplatin-sensitive and cisplatin-resistant human testicular, gastric, and ovarian carcinoma cell lines using 96 h continuous drug exposure in a sulforhodamine-B assay. In three cisplatin-sensitive testicular carcinoma cell lines, lobaplatin and cisplatin showed comparable antitumor activity. The 50% growth-inhibitory concentrations (IC50 values) determined for cisplatin ranged from 0.1 to 0.4 μM, and those found for lobaplatin ranged from 0.25 to 0.5 μM. Carboplatin showed markedly lower cytotoxicity in all cell lines tested. Lobaplatin was not cross-resistant to cisplatin in a 10-fold cisplatin-resistant testicular carcinoma cell line and showed only weak cross-resistance in a 20-fold cisplatin-resistant ovarian carcinoma cell line. In contrast, complete cross-resistance between cisplatin and lobaplatin occurred in two cisplatin-resistant human gastric carcinoma cell lines, which were 3.3- and 9-fold resistant to cisplatin and 3.1- and 6.5-fold resistant to lobaplatin, respectively. Furthermore, lobaplatin showed significant activity against cisplatin-resistant human ovarian and testicular carcinoma xenografts in vivo. These data indicate a high level of activity for lobaplatin at clinically achievable concentrations in drug-sensitive testicular, ovarian, and gastric carcinoma cell lines and a lack of complete cross-resistance to cisplatin. Further clinical development of lobaplatin is clearly warranted. 相似文献

AIMS: To investigate the correspondence between readiness for behaviour change in general and readiness for alcohol related help-seeking in particular. A related aim was to examine how, if at all, measures of dependence severity, use, and consequences were related to a composite measure depicting agreements and disagreements between general change readiness and help-seeking readiness. METHODS: Non-treatment seeking alcohol-dependent patients, numbering 549, from general hospitals in Germany were interviewed. RESULTS: When taking into account both dimensions of motivation, findings indicate 42% of the subjects were characterized by different motivation levels regarding readiness for change and readiness for help-seeking. Higher help-seeking readiness was associated with higher alcohol problem severity. Readiness to change was not affected by alcohol problem severity. CONCLUSIONS: Findings underscore the need to evaluate both motivational constructs in determining clients' need and receptivity to formal help. 相似文献

OBJECTIVE: To explore relationships of smoking and risk drinking status, nicotine and alcohol dependence, and anxiety, depressive, and somatoform disorders with overweight and obesity. RESEARCH METHODS AND PROCEDURES: A probability sample was drawn that was representative for the adult general population, 18 to 64 years of age, in one region of Germany; the participation rate was 70.2%. After excluding those who were pregnant or had a current eating disorder according to the DSM-IV, 4063 individuals remained. Overweight and obesity were defined according to the BMI that was assessed in the face-to-face in-home standardized interview (Composite International Diagnostic Interview) on psychiatric disorders. RESULTS: Men with a former nicotine dependence had higher odds of being overweight than men who never had a nicotine dependence (adjusted odds ratio, 1.5; confidence interval, 1.1 to 2.1). Men at current risk for drinking and current alcohol-dependent or abusing men had lower odds of being overweight compared with men who never were alcohol dependent, abusing, or at risk for drinking (adjusted odds ratio, 0.3; confidence interval, 0.8 to 0.9). Effect sizes were small. No relationship of overweight with depressive, anxiety, or somatoform disorders was found in the multivariate analysis. DISCUSSION: There is a relationship between being overweight and nicotine and alcohol dependence or abuse among men but not among women. Even though one reason for women to refrain from quitting smoking is the fear of weight gain, these results do not support this. This information could help convince women to try to quit smoking. 相似文献

BACKGROUND: Evidence suggests that nicotine-dependent smokers are at increased risk for psychiatric comorbidity but general population data that included the number of nicotine dependence and withdrawal symptoms according to DSM-IV, the Fagerstrom Test for Nicotine Dependence (FTND), somatoform disorders and the number of psychiatric diagnoses are rare. The goal of the present study was to analyse relationships of smoking and nicotine dependence with psychiatric disease and whether psychiatric disease predicts the sustaining of smoking after three years. METHODS: Cohort study with a random adult population sample in a northern German region (N = 4075) including a baseline measurement of ever daily smokers aged 18-64 (n = 2458), a first follow-up of the current smokers at baseline (n = 1552) after 30 months and a second follow-up after 36 months. Measures included DSM-IV diagnoses by the Composite International Diagnostic Interview, FTND, smoking cessation by interview. RESULTS: Current daily smokers showed higher odds of a substance use disorder other than nicotine dependence compared with never smokers (odds ratio, OR, 4.6; confidence interval, CI, 2.9-7.2), affective (OR 1.8; CI 1.4-2.5), anxiety (OR 1.6; CI 1.2-2.0) or somatoform disorder (OR 1.4; CI 1.0-1.8). DSM-IV nicotine dependence and the FTND were positively related with the number of psychiatric diagnoses. Psychiatric comorbidity did not predict the maintenance of smoking or quitting. CONCLUSIONS: Findings of increased rates of mental disorders among smokers and nicotine-dependent smokers in the adult general population are supported by this study. The number of nicotine dependence and withdrawal symptoms are related to mental disorders. In addition, somatoform disorders show relationships with smoking similar to relationships with depressive or anxiety disorders. The intention to stop smoking should be proactively supported among these comorbid patients. 相似文献

The aim of this study was to develop recommendations for interventions aiming at reducing health risks due to tobacco smoking in pregnant women, women postpartum and their infants. Meta-Analyses and selected studies are summed up. Epidemiological findings and health risks due to smoking are summed up. Subsequently findings from intervention studies are cross-referenced and integrated as recommendations. Interventions may be divided into three categories: 1. interventions to obtain abstinence in pregnancy, 2. interventions for relapse prevention after abstinence has been attained in pregnancy, 3. interventions aimed at reducing exposure to environmental tobacco smoke in homes with children. Empirical evidence is cross-referenced to the following points: 1. Self-help materials, 2. brief counselling, 3. more time-consuming counselling, 4. interventions to reduce exposure to environmental tobacco smoke and 5. interventions by midwives. Results from meta-analyses as well as results from selected studies suggest the following recommendations: 1. use of a trusting relationship in counselling, 2. repeated counselling, 3. complementary use of self-help materials; self-help material alone is not effective enough, 4. use of state-of-the-art counselling approaches and, 5. theoretical foundation and appropriate individualized counselling. 相似文献
