Intraosseous hemangioma in parietal bone

Abstract

Abstract-Objective:To estimate rates, predictors, and prognostic importance of recanalization in an unselected series of patients with stroke treated with IV thrombolysis. Methods: We performed a CT angiography or transcranial Doppler (TCD) follow-up examination 24 hours after IV thrombolysis in 64 patients with documented occlusion of the intracranial internal carotid or middle cerebral artery (MCA). Complete recanalization was defined by a rating of 3 on the Thrombolysis in Myocardial Infarction or 4/5 on the Thrombolysis in Brain Ischemia grading scales. Information about risk factors, clinical features, and outcome was prospectively collected by standardized procedures. Results: Complete recanalization was achieved in 36 of the 64 patients (56.3%). There was a nonsignificant trend of recanalization rates to decline with a more proximal site of occlusion: 68.4% (M2 segment of MCA), 53.1% (M1 segment), and 46.2% (carotid T) (p for trend ϭ 0.28). Frequencies of vessel reopening were markedly reduced in subjects with diabetes (9.1% vs 66.0% in nondiabetics, p Ͻ 0.001) and less so in subjects with additional extracranial carotid occlusion (p ϭ 0.03). Finally, complete recanalization predicted a favorable stroke outcome at day 90 independently of the information provided by age, NIH Stroke Scale, and onset-to-needle time. Conclusions: We found a high rate of vessel recanalization after IV thrombolysis occlusion. However, recanalization was infrequent in patients with diabetes and extracranial carotid occlusion. Information on recanalization was a powerful, early predictor for clinical outcome.

Antemortem trauma and survival in the late Middle Pleistocene human cranium from Maba, South China

“…Rarely a meningioma may become intradiploic, extend onto the external surface, and displace the external table outward (30)(31)(32). Hemangiomas are benign, solitary tumors formed by proliferating blood vessels (33) that are rarely found in the cranium (34,35); the lesion originates in the diploë and can erode through either table. Metastatic neoplasms produce round vault perforations with dentate margins (36).…”

An ectocranial lesion on the middle Pleistocene human cranium from Hulu Cave, Nanjing, China

“…Hemangiomas are generally benign, solitary tumors formed by proliferating blood vessels, varying in size from small to moderately large (Politi et al, 2005). Very rarely (\1% of cases) they may be found in the cranium, including the parietal and frontal regions (Khanam et al, 2001;Paradowski et al, 2007). However, as with porotic hyperostosis, the lesion originates in the diploic space, and it can erode through either table, producing openings on the external surfaces.…”

A Needs Analysis Study for Esl Students at University Level in Sri Lanka

“…Concerning subjective needs, practical information about the students' attitude towards the target language, their expectations, and their level of confidence, the motivation behind learning a particular language program are the key aspects. Paradowski (2002) considers that the first step of every syllabus design should be needs analysis, i.e. a set of techniques and procedures used for obtaining information about the learners and situations and purposes for which they want to learn the language 6 .…”
