A systematic review and meta-analysis of the treatments of varicose veins.

OBJECTIVES: Several treatment options exist for varicose veins. In this review we summarize the available evidence derived from comparative studies about the relative safety and efficacy of these treatments. METHODS: We searched MEDLINE, Embase, Current Contents, Cochrane Central Register of Controlled Trials (CENTRAL) expert files, and the reference section of included articles. Eligible studies compared two or more of the available treatments (surgery, liquid or foam sclerotherapy, laser, radiofrequency ablations, or conservative therapy with compression stockings). Two independent reviewers determined study eligibility and extracted descriptive, methodologic, and outcome data. We used random-effects meta-analysis to pool relative risks (RR) and 95% confidence intervals (CI) across studies. RESULTS: We found 39 eligible studies (30 were randomized trials) enrolling 8285 participants. Surgery was associated with a nonsignificant reduction in the risk of varicose vein recurrence compared with liquid sclerotherapy (RR, 0.56; 95% CI, 0.29-1.06) and all endoluminal interventions (RR, 0.63; 95% CI, 0.37-1.07). Studies of laser and radiofrequency ablation and foam sclerotherapy demonstrated short-term effectiveness and safety. The quality of evidence presented in this review was limited by imprecision (small number of events), short-term follow-up, and indirectness (use of surrogate outcomes). CONCLUSION: Low-quality evidence supports long-term safety and efficacy of surgery for the treatment of varicose veins. Short-term studies support the efficacy of less invasive treatments, which are associated with less periprocedural disability and pain.

Complementary and Alternative Medicine Use by Patients From the Gulf Region Seen in the International Practice of a Tertiary Care Medical Center.

BACKGROUND: Patients from various countries may have unique patterns of using complementary and alternative medicine (CAM) and unique reasons for using it. OBJECTIVE: Our objective was to assess the use of CAM among patients from the Gulf region attending the Executive and International Health Program of the Department of General Internal Medicine at Mayo Clinic in Rochester, Minnesota. METHODS: This cross-sectional survey was administered to all patients who were from the Gulf region and were undergoing outpatient evaluation in the Executive and International Health Program. After their initial medical evaluation by a physician, the patients were invited to anonymously complete the modified International Complementary and Alternative Medicine Questionnaire. RESULTS: The survey was completed by 69 patients (41 women, 27 men; mean age, 45.4 years). The most frequently seen providers for CAM treatments were physicians (71.0% of patients), spiritual healers (29.0%), and chiropractors (20.3%). CAM treatments most frequently received from a physician were massage therapy (51.0%), hijama (38.8%), spiritual healing (24.5%), and acupuncture or herbs (16.3%). The most frequently used dietary supplements were ginger (42.0%), bee products (30.4%), and garlic (27.5%). The most common self-help therapies were prayers for health (68.1%), meditation (15.9%), and relaxation techniques (11.6%). CAM therapy, including visits to CAM providers, was used by 92.8% of patients. CAM was mainly used to improve well-being and long-term health conditions rather than for acute illnesses. CONCLUSION: The use of CAM was high among our patients from the Gulf region, and the CAM therapies used by this population differed from the ones used by US patients. Physicians providing care to patients from the Gulf region should be aware of how the use of CAM may affect the care needs of these patients.

Predictors of blood pressure control in patients with diabetes and hypertension seen in primary care clinics.

BACKGROUND: Blood pressure (BP) is not well controlled in the majority of patients with both diabetes and hypertension. This study was designed to identify predictors of BP control in patients with both diabetes and hypertension who are seen in primary care clinics. METHODS: This retrospective study was conducted by identifying a cohort of patients diagnosed with diabetes before January 1, 2000 (inception) who met predefined criteria for hypertension at inception and who received primary care in the ensuing 3-year study period (January 1, 2000, to February 31, 2002). Using the mean of all BP values between January 1, 2002, and December 31, 2002, subjects were divided into two groups: those with controlled BP and those with uncontrolled BP. The distribution of clinical predictors was compared between the two groups. Independent predictors were identified using multivariate logistic regression. RESULTS: Predictors of poor BP control were as follows: 1) isolated systolic hypertension at inception (OR= 0.62, CI = 0.47 to 0.82); 2) uncontrolled BP at inception (OR = 0.71, CI = 0.55 to 0.93); 3) use of oral hypoglycemic drugs versus diet and exercise alone or insulin use (OR = 0.73, CI = 0.56 to 0.95); 4) use of three or more antihypertensive drugs (OR = 0.74, CI = 0.56 to 0.97); and 5) older age (OR = 0.98, CI = 0.97 to 0.99). Predictors of better control were 1) use of nitrates (OR = 1.82, CI = 1.26 to 2.64); 2) history of coronary heart disease (OR = 1.47, CI = 1.08 to 2.00); and 3) at least one annual visit to subspecialist physician (OR = 1.43, CI = 1.09 to 1.88). CONCLUSIONS: Patients with both diabetes and hypertension who are older, have isolated systolic hypertension, use oral hypoglycemic drugs, or use three or more antihypertensive drugs should be targeted for better BP control. The roles of nitrate medication and subspecialist physicians in achieving better BP control needs further study.

Women with diabetes have poorer control of blood pressure than men.

OBJECTIVE: Diabetes is associated with a higher coronary heart disease (CHD) mortality in women compared with men. Less aggressive control of the CHD risk factors in women can contribute to this excess mortality. Because hypertension has a high prevalence in subjects with diabetes, we compared the control of this risk factor between men and women. METHODS: This was a retrospective cohort study comparing blood pressure levels and trends over a 1-year period between men and women with diabetes receiving primary care. Using a chronic disease registry database, subjects with type 1 and type 2 diabetes, aged >or=18, were identified for inclusion. Mean weighted systolic blood pressure (SBP) and diastolic blood pressure (DBP) were calculated for subjects with multiple longitudinal readings. Subjects were classified into four blood pressure control categories based on the mean weighted blood pressure. Comparisons were made between men and women before and after controlling for baseline characteristics. RESULTS: A total of 3181 subjects (46% women) were included in the study. More women than men were in the moderate and severely elevated blood pressure categories (40% and 6% compared with 32% and 5%, respectively, p<0.001). The unadjusted mean SBP was 3 mm Hg higher in women (139 mm Hg in women compared with 136 in men, p<0.001). These differences remained significant after controlling for baseline variables. CONCLUSIONS: In subjects with diabetes receiving medical care, women had poorer control of blood pressure and a significantly higher mean SBP compared with men. These findings might partially explain the excess CHD mortality in women with diabetes.
