Antioxidant effect of virgin olive oil in patients with stable coronary heart disease: a randomized, crossover, controlled, clinical trial.

The Mediterranean diet, in which olive oil is the main source of fat, has been associated with a reduced incidence of coronary heart disease (CHD) and low blood pressure levels. Virgin olive oil (VOO), besides containing monounsaturated fat, is rich in phenolic compounds (PC) with antioxidant properties. The aim of this study was to examine the antioxidant and anti-hypertensive effect of two similar olive oils, but with differences in their PC (refined: 14.7 mg/kg versus virgin: 161.0 mg/kg), in 40 males with stable CHD. The study was a placebo controlled, crossover, randomized trial. A raw daily dose of 50 mL of VOO and refined olive oil (ROO) were sequentially administered over two periods of 3 weeks, preceded by 2-week washout periods in which ROO was used. Lower plasma oxidized LDL (p < 0.001) and lipid peroxide levels (p = 0.003), together with higher activities of glutathione peroxidase (p = 0.033), were observed after VOO intervention. Systolic blood pressure decreased after intake of VOO (p = 0.001) in hypertensive patients. No changes were observed in diastolic blood pressure, glucose, lipids, and antibodies against oxidized LDL. Consumption of VOO, rich in PC, could provide beneficial effects in CHD patients as an additional and complementary intervention to the pharmacological treatment.

Complications of tibial shaft soccer fractures.

A retrospective study of AO type 42 tibial diaphyseal fractures that presented to a teaching hospital over a 54 month period was made to identify the proportion sustained whilst playing soccer, determine their characteristics and report treatment and outcome. Sport accounts for 73/329 (22.1%) of these fractures and soccer 58/73 (79. 5%) of these. All patients were male with mean age of 24.3 years (range 8-48). Fifty-four fractures were closed and 93.1% (54/58) were situated in the middle third or at the junction of the middle and distal thirds of the diaphysis. Fifty-six (96.6%) had simple or wedge patterns and 45 (77.6%) were right sided. Forty-four (76.2%) were treated non-operatively in plaster, 12 (20.3%) by intramedullary nails and two (3.4%) with external fixators. Two patients were lost to follow-up and the remaining 56 fractures united at a mean of 6.5 months. There were 21 complications in 19/56 (33.9%) patients which included 8/56 (14.3%) delayed/non-unions requiring surgery. There was a significantly higher complication rate for operated fractures (p<0.005) but no significant link to AO fracture type. Thus we cannot assume that treatment of these common fractures is without risk, especially if they are treated operatively.

[The predictive signs of multivessel coronary disease in echocardiography with dobutamine].

AIMS: To assess the ability of dobutamine echocardiography to detect multivessel coronary artery disease and to determine predictive factors for multivessel disease with or without beta-blockers. PATIENTS AND METHODS: A total of 101 patients underwent dobutamine stress echocardiography and coronary angiography (evaluation of chest pain 76, extent of coronary disease after myocardial infarction 19, other indications 6). RESULTS: Ten patients in whom the test was prematurely terminated were excluded. Out of 91 patients who underwent dobutamine echocardiography, 54 patients had multivessel disease (sensitivity of dobutamine test 93%, specificity 46%). Heart rate at the maximum dose of dobutamine or atropine was 88 +/- 21 beats/min for multivessel diseases and 104 +/- 21 beats/min without multivessel disease (p < 0.001). A cut-off value < 94 beats/min discriminated patients at risk for multivessel disease. After adjusting for treatment with beta-blockers, heart rate < 94 beats/min, ECG signs of ischemia, and abnormalities on baseline echocardiogram with remote asynergies during dobutamine testing were independent predictors of multivessel disease in the multivariate analysis (probability > 90% when at least two factors were present). CONCLUSION: A heart rate < 94 beats/min at peak dose of dobutamine or after atropine, ECG signs of ischemia, and the presence of abnormalities on echocardiogram at rest with remote asynergies during dobutamine stress testing were independent predictive factors of multivessel coronary artery disease.

Aquaflo pump vs FMS 4 pump for shoulder arthroscopic surgery.

A prospective controlled trial was carried out to compare two different fluid delivery systems used for shoulder arthroscopy. One an advanced pump system that controls both pressure and flow of fluid delivered, the other an air-driven diaphragm pump that only controls fluid pressure. Blood loss, presence of bleeding vessels and visual clarity were parameters used to assess the pump systems. There was no difference between the pumps in straightforward shoulder procedures. However, complicated and prolonged procedures benefited from the use of the advanced pump system.
