Examining interactions of illness perceptions, avoidance behavior and patient status in predicting quality of life among people with irritable bowel syndrome.

Illness perceptions (IPs) and avoidance behavior both predict quality of life (QoL) in people with irritable bowel syndrome (IBS). This study examined whether the effects of IPs on QoL are mediated by avoidance behaviors, and whether this mediation is moderated by participant treatment-seeking status. People with self-reported IBS ( = 253) answered a survey assessing QoL, IPs, avoidance behaviors, and treatment-seeking status.

Iohexol vs. ioxaglate in lower extremity angiography: a comparative randomized double-blind study in 80 patients.

The aim of this study was to detect clinically relevant differences between iohexol 300 mgI/ml and ioxaglate 320 mgI/ml in lower extremity arteriography. In this randomized double-blind study, 40 patients were examined with iohexol and 40 patients with ioxaglate. Adverse events were evaluated by recording the time of onset and the duration of possible adverse events: during or immediately following the contrast medium injections, after 6 h, and after 24 h following these injections.

Hairy cell leukemia preferentially expresses the IgG3-subclass.

Surface IgG expression of 29 cases of hairy cell leukemia (HCL) was assessed using IgG-subclass-specific monoclonal and F(ab)'2 polyclonal antibodies. A marked preference for the IgG3 subclass was found, as 16 of 19 IgG-positive HCL's expressed IgG3. In 10 cases, IgG3 was concurrently expressed with other heavy chains.
