The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of 100 mg Pycnogenol daily (oral capsules) in a 3 month study in patients with osteoarthritis (OA). OA symptoms were evaluated by WOMAC scores, mobility by recording their walking performance (treadmill). Treatment (77 patients) and placebo group (79) were comparable for age, sex distribution, WOMAC scores, walking distances and use of antiinflammatory drugs. The global WOMAC score decreased by 56% (p < 0.05) in the treatment group versus 9.6% in the placebo group. Walking distance in the treadmill test was prolonged from 68 m at the start to 198 m after 3 months treatment (p < 0.05), under placebo, from 65 m to 88 m (NS). The use of drugs decreased by 58% in the treatment group (p < 0.05) versus 1% under placebo. Gastrointestinal complications decreased by 63% in the treatment group, but only 3% under placebo. Overall, treatment costs were reduced significantly compared with placebo. Foot edema was present in 76% of the patients of the treatment group at inclusion and in 79% of the controls. After 3 months edema decreased in 79% of Pycnogenol patients (p < 0.05) vs 1% in controls. In conclusion, Pycnogenol offers an option for reduction of treatment costs and side effects by sparing antiinflammatory drugs.

Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb, Lipohep, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.

LSTs represent approximately 5% of all precancerous colorectal lesions in the Italian population and are prevalent in the proximal colon. These lesions are no more likely to harbor advanced histology than similar-sized polypoid lesions. Large nodularity or depressed surface are risk factors for advanced histology.

The aim of this independent study was to investigate differences in efficacy between oxerutins (Venoruton) and 500 mg micronized diosmin + hesperidin (D+H) (Daflon) in patients with chronic venous insufficiency (CVI), evaluating venous-related quality of life (Ve-QOL). A first group of 90 patients with severe venous hypertension (CVI, ankle swelling) was randomized to treatment with oxerutins or D+H. The oxerutins group received oral oxerutins (2 g/day); the D+H group received 3 (500 mg) tablets daily every 8 hours for 8 weeks. A second group of 122 comparable patients was included in a registry following the same study format. The 2 treatments were administered with the same methods and procedures. Clinical conditions were comparable. All patients completing 8 weeks of treatment were included in a registry. Specialists or general practitioners included patients when they considered that clinical conditions were compatible with treatment indications using 1 of the 2 treatments on the basis of their evaluation and experience. When cases were compatible with the registry, the prescribing physician communicated the case to our monitoring center. Patients were evaluated without interfering with their treatment. The main target of evaluation for this study was the change in Ve-QOL (range, 0-100) induced by treatment. A specific Ve-QOL questionnaire was used for this study. Ve-QOL score is a specific expression of the changes in QOL induced by CVI in patients between 35 and 75 years old (defined in our population studies) in which no other significant clinical disease is present (as a confounding factor affecting QOL). Two hundred twelve patients completed the 2 parts of the study. The 2 treatment groups were comparable for age and gender distribution. The mean age was 42 years (SD +/-5.5) in the oxerutins group and 41.5 (SD +/-6) in the D+H group. There were no differences in the severity of CVI between the treatment groups at inclusion. A significant decrease (46.8%, p<0.05) in Ve-QOL score; that is, improvement, was observed in the oxerutins group. The change in Ve-QOL was significantly less in the D+H group (15.5%). In conclusion, CVI, venous microangiopathy, and edema were significantly improved by the treatment with oxerutins; the improvement in QOL was significantly greater in the oxerutins group. The comparison with D+H indicates that oxerutins is comparatively more effective on Ve-QOL and on signs/symptoms of CVI.

This study evaluated the effects of Pycnogenol as an adjunct to angiotensin-converting enzyme (ACE)-inhibitor ramipril treatment of hypertensive patients presenting with early signs of renal function problems. One group of 26 patients was medicated with 10 mg ramipril per day only; a second group of 29 patients took Pycnogenol in addition to the ACE inhibitor over a period of 6 months. At trial end, a lowered systolic and diastolic blood pressure was found in both groups, with a significant further reduction of diastolic pressure in the group given Pycnogenol in addition to ramipril. The major aim of this study was the investigation of kidney-protective effects of Pycnogenol. Urinary albumin decreased from 87 +/- 23 to 64 +/- 16 mg/d with ramipril only. Additional Pycnogenol lowered albumin significantly better from 91 +/- 25 to 39 +/- 13 mg/day (P < .05). In both groups, serum creatinine was lowered; however, only in the combination treatment group did the effect reached statistical significance. In both groups, CRP levels decreased from 2.1 to 1.8 with ramipril and from 2.2 to 1.1 with the ramipril-Pycnogenol combination; the latter reached statistical significance. Kidney cortical flow velocity was investigated by Doppler color duplex ultrasonography. Both systolic and diastolic flow velocities increased significantly after 6 months medication with ramipril. The addition of Pycnogenol to the regimen statistically significantly further enhanced kidney cortical flow velocities, by 8% for diastolic flow and 12% for systolic flow, relative to values found for the group taking ramipril only. The protective effects of Pycnogenol for initial kidney damage found in this study warrant further research with a larger number of patients and over a longer period of time.
