Abstract. Fluorescence imaging using the dye indocyanine green as a contrast agent was investigated in a prospective clinical study for the detection of rheumatoid arthritis. Normalized variances of correlated time series of fluorescence intensities describing the bolus kinetics of the contrast agent in certain regions of interest were analyzed to differentiate healthy from inflamed finger joints. These values are determined using a robust, parameter-free algorithm. We found that the normalized variance of correlation functions improves the differentiation between healthy joints of volunteers and joints with rheumatoid arthritis of patients by about 10% compared to, e.g., ratios of areas under the curves of raw data.

Objectives. The aim of this study was to evaluate the influence of moderate beer consumption on lipid metabolism and antioxidant activity in patients (pts) with coronary artery disease (CAD). Subjects. Forty-eight male pts with CAD not alcohol beverages consumers were randomly divided into experimental (EG) and control (CG) groups, 24 pts each. Setting. Rehovot University Hospital, Israel. Intervention. Every patient of the EG during a period of 30 consecutive days consumed 330 ml of Maccabee beer (Ͼ20 g of alcohol). The pts of the CG did not consume alcohol during the trial period. Methods. A wide range of tests including total cholesterol, LDL-C, HDL-C, total tocopherol and ␣-tocopherol. Results. Only in the pts of the EG were found a tendency to an increase of the level of HDL-C and a statistically significant rise in the level of total tocopherol (P Ͻ 0.025) and ␣-tocopherol (P Ͻ 0.025). Conclusions. Even a short period of moderate beer consumption leads to some favourable biochemical changes in blood of pts with CAD which are widely regarded as indicators of CAD prevention.

Skin microcirculation and skin temperature of 10 healthy subjects (6 men and 4 women, 20-44 yr of age) without any vascular diseases were registered when a thermoindifferent tap water iontophoresis was applied. The aim of this controlled study was to evaluate the development of skin hyperemia after the intake of 500 mg of acetylsalicylic acid (ASA). The measurement was conducted by laser-Doppler flowmetry on the proximal forearm. The skin temperature was measured before and after the treatment by an infrared thermometer. In all persons there was an intense erythema on the side of the cathode and only a modest one on the side of the anode. Without ASA preliminary treatment, the cutaneous flow showed an increase of 106% at the anodal side and that of 834% at the cathodal side (P < 0.001). After ending tap water iontophoresis, the skin temperature increased more on the cathode side than on the anode side (P < 0.001). After the intake of 500 mg ASA, the increase of the flow was 78% at the anode and 88% at the cathode. The comparison of the skin microcirculation did not show any differences at the anodal side when acetylsalicylic acid was taken before, but a strong suppression of the galvanic erythema at the cathodal side was observed after the intake of ASA. There is a direct influence of acetylsalicylic acid on the induction of the neurogenic inflammation caused by a galvanic erythema. The intensity of the induced erythema correlates with the analgesic effects of constant current treatment. An attenuation of the electrotherapeutic analgesia is possible.

Chronic pain has been recognized as a major worldwide health care problem. Today, medical experts and health agencies agree that chronic pain should be treated with the same priority as the disease that caused it, and patients should receive adequate pain relief. To achieve good analgesia, patient adherence to a prescribed pain treatment is of high importance. Patients with chronic pain often do not use their medication as prescribed, but change the frequency of intake. This can result in poor treatment outcomes and may necessitate additional emergency treatment, which increases the overall costs. Factors that influence adherence include knowledge of the disease, realistic treatment expectations, perceived benefit from treatment, side effects, depression, dosing frequency, and attitudes of relatives/significant others toward opioids. Addressing all these factors should ensure a good treatment outcome. Good adherence to pain therapy is associated with improved efficacy in pain relief and quality of life. Opioids have become an integral part of the treatment of moderate to severe chronic noncancer pain. They may cause unpleasant side effects such as nausea, vomiting, and constipation. Patients should be informed adequately about side effects, which should be treated pro-actively to foster adherence to treatment. Signs of tolerance, hyperalgesia, and drug abuse should be monitored as these may occur in some patients. An individualized treatment algorithm with a clear treatment goal and regular treatment reassessment is key for successful treatment. Long-acting opioids offer sustained pain relief over 24 hours with manageable side effects-they simplify treatment thereby supporting treatment adherence.
