RESUMEN. Introducción: los injertos de hueso autólogo para elevación del piso del seno maxilar son ampliamente aceptados para la reconstrucción de defectos en el reborde alveolar; sin embargo, existen sitios donantes que no han sido debidamente explorados y que pueden representar opciones válidas para este tipo de procedimientos. El objetivo de este estudio consistió en evaluar el comportamiento de los injertos

We conclude that the investigated polymorphisms are not associated with individual susceptibility to colorectal cancer.

BACKGROUND AND PURPOSE: Stent-like, self-expandable devices, the so-called flow diverters, are increasingly used for the treatment of wide-neck cerebral aneurysms. The immediate and short-term results are promising, but no long-term results are available. The purpose of our research was to report the long-term angiographic and cross-sectional imaging results after placement of a PED in 12 patients with wide-neck intracranial aneurysms.

Mean platelet volume (MPV) was recently published as a possible marker of coronary artery disease in patients at high risk for major adverse cardiac events. Because platelets play an important role in atherosclerosis, we examined the relationship between critical limb ischemia (CLI) and MPV in patients with peripheral arterial occlusive disease (PAOD). Our study comprised 2124 PAOD patients. Univariate logistic regression was performed to analyze potential predictors for CLI. Nagelkerke’s R² is reported. Cross validation was performed using the leave-one-out principle. ROC analyses were performed to identify the best cut off value for MPV predicting CLI; to this end, Youden’s index was calculated. For CLI diabetes (p < 0.001, OR 2.44, 95% CI 1.97–3.02), hsCRP (p < 0.001, OR 1.01, 95% CI 1.01–1.01), age (p < 0.001, OR 1.05, 95% CI 1.04–1.06), thrombocytosis (p = 0.025, OR 1.84, 95%CI 1.08–3.14), and MPV (p = 0.003, OR 0.84, 95% CI 0.75–0.94) were significant independent predictors for CLI. ROC analysis (AUC: 0.55, 95% CI 0.52–0.58, p < 0.001) showed ≤10.2 as the best cut off value for MPV to predict CLI. As there is a significant relationship between low MPV and a high risk for CLI in PAOD patients, MPV can be used to identify patients who are likely to develop CLI.

We report the immediate technical and clinical outcome of a new self-expanding fully retrievable stent in the treatment of acute ischemic stroke. Eleven consecutive patients with acute intracerebral artery occlusions were treated with a self-expandable fully retrievable intracranial stent (Solitaire AB). Four patients had an occlusion of the basilar artery, five had a middle cerebral artery occlusion and two had terminal carotid artery occlusions. Recanalization results were assessed by follow-up angiography immediately after the procedure. Neurologic status was evaluated before and after treatment (90-day follow-up) according to the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scales (mRS). Successful revascularization (TICI 2a/b and 3) was achieved in 11 of 11 (100%) patients, a TICI 3 state was accomplished in two (18%) patients, and partial recanalization or slow distal branch filling with filling of more than two-thirds of the vessel territory (TICI 2a/2b) was achieved in nine (82%) patients. The stent was removed in all patients. The mean time from stroke symptom onset to recanalization was 339 minutes (+/– 114.3 minutes). NIHSS on admission was 16.09 (+/– 4.7). Almost two-thirds of the patients (61.2%) improved by >6 points on the NIHSS at discharge, and 30% showed a mRS of <2 at 90 days. Mortality was 9%. One patient with a BA occlusion had a massive brain stem infarction and died two days after the procedure. There were no intracranial hemorrhages. The use of the Solitaire in ischemic stroke patients shows encouraging results. However, further prospective large randomized trials are mandatory to confirm these early results.
