Comparative Study Controlled Clinical Trial
Comparing results of digital photoplethysmography in two groups of chronic obstructive pulmonary disease patients with and without high pulmonary artery pressure.
Digital photoplethysmography (D-PPG) is a newly introduced method of optical screening of deep vein thrombosis (DVT) by recording changes in the size of limb due to tissue fluid. ⋯ Our results showed that the rate of positive D-PPG test results is slightly higher in patients with pulmonary hypertension, but this difference is not statistically significant. Therefore, increased PAP could be excluded as a confounding factor of D-PPG test.

This report describes two complications of severe neurologic alterations (TIA, CVA) after foamed sclerotherapy injection. ⋯ Foam sclerotherapy can cause serious neurologic phenomenon even though the incidence is rarely described. Immediate treatment with 100% O2 and possible hyperbaric O2 therapy should be considered.

Randomized Controlled Trial
Long saphenous tunnel infiltration with levobupivicaine reduces rescue analgesia requirements following varicose vein surgery: randomized, double-blind, placebo-controlled trial [ISRCTN58431114].
To determine whether local anaesthetic infiltration of the long saphenous tunnel in patients undergoing unilateral, primary long saphenous stripping and multiple avulsions reduces early postoperative pain and requirement for opiate analgesia. ⋯ In varicose vein surgery, local anaesthetic infiltration to the groin wound and along the full length of the stripper track is associated with reduced postoperative pain and requirements for opiate analgesia.

The study was designed to analyse the risk indicators for a possible underlying malignancy and to evaluate whether extensive cancer screening is necessary in all patients with venous thromboembolism or not. ⋯ The risk of an underlying malignancy in patients with idiopathic venous thromboembolism is significantly higher. A moderate screening strategy has the capacity to identify the majority of the malignancies in such patients. We advocate simple laboratory tests, a chest X-ray and an abdominopelvic ultrasonography in order to search for an occult malignancy. A more extensive screening strategy may be considered for patients with suspicious findings for cancer, recurrent or bilateral venous thromboembolism and associated thrombosis in unusual sites.
