Aim: To compare the predictive power of different endothelial progenitor cell (EPC) phenotypic markers for future cardiovascular events., Methods: Peripheral blood was collected from 76 consecutive patients with acute coronary syndromes (ACS) who underwent percutaneous coronary intervention in our institute. The various EPC phenotypes of peripheral blood mononuclear cells were CD34+CD133+, CD34+KDR+, and CD 133+KDR+. The outcome endpoint included cardiovascular mortality, recurrent ACS, and hospitalization for decompensated heart failure during a 24-mo follow-up period., Results: CD34+CD133+ cells (P = 0.034), but not CD34+KDR+ (P = 0.35) or CD 133+KDR+ cells (P = 0.19), were found to predict recurrent ACS. We found no correlation between EPCs measured by any of the three phenotypic combinations of accepted CD markers and the total combination of these separate outcomes., Conclusion: The EPC CD34+CD133+ phenotype, but not the CD34+KDR+ or the CD 133+KDR+ phenotypes, is predictive of future adverse cardiovascular outcomes.

Headache interpreted as treatment failure may be encountered after FESS or pharmacological treatment for chronic sinusitis. This persistent symptom may lead, even in the presence of minimal sinus disease, to frequent office visits, medical treatment, primary surgery, and revision procedures. A prospective study of patients with a documented history and imaging-verified sinus disease with persistent atypical refractory headache were evaluated. Diagnostic measures included injection of local anesthetic and response to carbamazepine. Severe neuralgia of the supraorbital nerve was identified in 11 patients with chronic sinusitis, treated either medically or surgically before inclusion in the study. Eight of the patients underwent surgery for sinus disease, and five of them had revision surgery because of persisting complaints. All patients responded favorably to the local injection, and eight were treated with carbamazepine. In certain cases, headache in sinusitis patients may be caused or aggravated by supraorbital neuralgia. Sinus disease is possibly a causative factor but conceivably plays the role of a "red herring." This readily diagnosed and treated coexistence may be more prevalent than recognized formerly.
