This study evaluated the specific effectiveness of cognitive-behavior therapy (CBT) combined with medication tapering for benzodiazepine discontinuation among generalized anxiety disorder (GAD) patients by using a nonspecific therapy control group. Sixty-one patients who had used benzodiazepines for more than 12 months were randomly assigned to the experimental conditions. Nearly 75% of patients in the CBT condition completely ceased benzodiazepine intake, as compared with 37% in the control condition. Results of the 3-, 6-, and 12-month follow-ups confirmed the maintenance of complete cessation. Discontinuation rates remained twice as high in the CBT condition. The number of patients who no longer met GAD criteria was also greater in the CBT condition. The addition of specific CBT components thus seemed to facilitate benzodiazepine tapering among patients with GAD. 相似文献

Primary cutaneous large B-cell lymphomas (PCLBCL) have historically been a matter of debate in the literature. The 2005 World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) classification scheme segregated cutaneous B-cell lymphomas into 3 groups: primary cutaneous marginal zone B-cell lymphoma, primary cutaneous follicle center cell lymphoma, and primary cutaneous diffuse large B-cell lymphoma (PCDLBCL), "leg type" (PCDLBCL-LT). Additionally, the WHO-EORTC classification scheme utilized the term PCLBCL "other" not otherwise specified (NOS) type for rare cases of PCLBCL not belonging to either the "leg type" or the primary cutaneous follicle center cell lymphoma group. In this study, we retrospectively assessed the histomorphologic features of 79 cases of PCDLBCLs, including those of "leg type" and "other" NOS type, to further categorize the histologic spectrum of these unusual cutaneous neoplasms. The histologic diagnosis of PCLBCL usually poses little diagnostic difficulty; however, some cases may adopt unusual or unfamiliar appearances mimicking other lymphoproliferative disorders or other malignant neoplasms. Seventy-nine cases, occurring in 37 men and 42 women, aged 34-94 years, were analyzed. Fifty-three cases were classified as "leg type" and 26 cases were classified as "other" NOS type using the WHO-EORTC classification. Of the 53 cases classified as "leg type," 33 were women and 20 were men; of the 26 cases of "other" NOS type, 9 were women and 17 were men. In the "leg type" category, 31 cases were located on the lower extremities, 5 cases on the face, 5 cases on the arm, 3 cases on the chest, 2 cases on the shoulder, 2 cases on the back, 1 case on the trunk, 1 case on the buttock, 1 case on the supraclavicular area, 1 case on the head, and 1 case on the flank. Of the "other" NOS type category, 8 cases were located on the face, 5 cases on the shoulder, 3 cases on the head, 2 cases on the abdomen, 2 cases on the chest, 1 case on the trunk, 1 on the vulva, 1 on the axilla, 1 on the back, 1 on the neck, and 1 on the hip. Most cases assessed showed the classic morphologic appearance of PCDLBCL, but cases mimicking Burkitt lymphoma (starry-sky pattern), natural killer-cell (NK) lymphoma, mycosis fungoides (epidermotropism), low-grade B-cell lymphomas, epithelial malignancies, and Merkel cell carcinoma were encountered in this series. The high frequency of these rare histologic patterns can be explained by a bias associated with consultation practice. Careful histologic examination and immunohistochemical stains were used to establish the correct diagnosis. The differential diagnosis of PCDLBCL is broad and difficult to define histologically. Knowledge of these rare histologic variants is necessary to avoid misinterpretation of these cases as nonlymphoid malignancies. 相似文献

Tobacco, alcohol, and coffee and cancer of the pancreas. A population-based, case-control study in Quebec, Canada 总被引:6,自引:0,他引:6
A population-based, case-control study of pancreatic cancer was carried out in greater Montreal between 1984 and 1988. A total of 179 cases and 239 population-based controls were interviewed. This study was part of the SEARCH program of the International Agency for Research on Cancer of the World Health Organization. A strong positive association was observed between total cigarette smoking and risk of pancreatic cancer (odds ratio [OR] = 3.76; 95% confidence interval [CI], 1.80 to 7.83). The OR for current smokers in the highest quintile of number of cigarettes was 5.15 compared with 3.99 for exsmokers. Those who consumed alcohol were in general at lower risk than nondrinkers. Coffee drinkers were collectively at lower risk than nondrinkers, particularly when coffee was consumed with meals, not on empty stomach. 相似文献

Some actions of insulin are mediated by inositolphosphoglycan (IPG) mediators. Deficient release of a putative d-chiro-inositol-containing (DCI) IPG mediator may contribute to insulin resistance in women with polycystic ovary syndrome (PCOS). Previously, we demonstrated that oral DCI supplementation improved ovulation and metabolic parameters in women with PCOS. However, whether oral DCI mediates an increase in the release of the DCI-IPG mediator and an improvement in insulin sensitivity in women with PCOS is unknown. We conducted a randomized controlled trial of DCI supplementation vs placebo in 11 women with PCOS who were assessed at 2 time points 6 weeks apart. Plasma DCI, DCI-IPG release during oral glucose tolerance test (AUCDCI-IPG), and insulin sensitivity (Si) by frequently sampled intravenous glucose tolerance test were assessed at baseline and end of study. The study was terminated early because of a sudden unavailability of the study drug. However, in all subjects without regard to treatment assignment, there was a positive correlation between the change in AUCDCI-IPG/AUCinsulin ratio and the change in Si during the 6-week period (r = 0.69, P = .02), which remained significant after adjustment for body mass index (P = .022) and after further adjustment for body mass index and treatment allocation (P = .0261). This suggests that, in women with PCOS, increased glucose-stimulated DCI-IPG release is significantly correlated with improved insulin sensitivity. The significant relationship between DCI-IPG release and insulin sensitivity suggests that the DCI-IPG mediator may be a target for therapeutic interventions in PCOS. 相似文献

OBJECTIVE: To assess the prevalence and correlates of hepatitis C virus infection in a sample of detained adolescents. DESIGN/SETTING/PARTICIPANTS: Cross-sectional prevalence study with 10- to 18-year-old adolescents who were consecutively admitted to a juvenile detention center in San Antonio, Tex. MAIN OUTCOME MEASURES: The prevalence of hepatitis C virus infection and associated risk factors. RESULTS: Of the 1002 participants, 75% were Hispanic and the mean age was 15 years. Twenty adolescents had laboratory data consistent with hepatitis C virus infection, giving an overall prevalence of 2.0% (95% confidence interval, 1.2-3.1). All adolescents infected with hepatitis C virus were Hispanic (13 boys and 7 girls). Although a high proportion of the participants reported having had intranasal drug use (55.6%), tattooing (50.5%), or body piercing (25.3%), the only factor significantly associated with hepatitis C virus infection was having a history of injection drug use. Injection drug use was reported by 5.3% of the participants but by 95% (19/20) of those infected with the hepatitis C virus. CONCLUSIONS: This study indicates that injection drug use was linked with the majority of hepatitis C virus infections in this population of detained adolescents, similar to findings in adults. These adolescents reported a high frequency of other behaviors that could potentially pose a risk for contracting bloodborne infections. Effective prevention and awareness programs in a detention setting need to be comprehensive and include screening, hepatitis A and B immunizations, and risk-reduction counseling. 相似文献
