Randomized Controlled Trial Comparative StudyEffects of pregabalin on acute herpetic pain and postherpetic neuralgia incidence.
Acute zoster pain usually disappears with regression of the rash but may be of significant intensity and prolonged duration leading to postherpetic neuralgia. We evaluated the effect of pregabalin on alleviation of acute zoster pain and onset of postherpetic neuralgia. ⋯ The study did not prove any statistically significant effect of pregabalin in pain relief in patients with acute zoster pain or in the onset of postherpetic neuralgia in comparison with the placebo. The use of pregabalin was related to a statistically significant increase in the appearance of adverse effects.

Influence of body position on hemodynamics in patients with ischemic heart disease undergoing cardiac surgery.
The cardiovascular response to decreased or increased preload in high-risk patients with ischemic heart disease enables us to understand the physiologic response to hemorrhage and its treatment. Although numerous studies have failed to show its effectiveness, the head-down position is still widely used to treat patients with hypotension and shock. The aim of our study was to evaluate the influence of body position on hemodynamics in high-risk patients undergoing coronary artery bypass graft surgery. ⋯ The results of our study showed a hemodynamic response similar to hemorrhage after placing the patients in a 20 degrees head-up position and improving hemodynamics in the head-down position in mechanically ventilated patients undergoing coronary artery bypass graft surgery.

Inflammation markers in patients with coronary artery disease--comparison of intracoronary and systemic levels.
Raised levels of inflammation markers are associated with worse prognosis in patients with coronary artery disease. It is generally believed, although it has never been proven, that inflammation markers are released from (un)stable plaques in coronary arteries. We investigated this issue by directly comparing levels of inflammation markers in coronary and systemic blood. ⋯ We observed that excess circulating inflammation markers, being characteristic of unstable coronary artery disease, are released from noncoronary sources. Thus, it may be speculated that systemic inflammation precedes local inflammation at the plaques, thereby transforming coronary disease from a stable to an unstable form.
