The etiology of ischemic stroke affects its prognosis, outcome and management. Our aims were to determine risk factors, clinical and imaging variables and prognostic differences in acute ischemic stroke subtypes. In this study, we prospectively investigated 264 consecutive patients with acute ischemic stroke between 1996 and 2000. All of the patients were categorized to one of four major ischemic stroke subtype based on TOAST (Trial of Org 10172 in Acute Stroke Treatment) criteria. The mean age was greater in patients with stroke of undetermined etiology (SUE). Prevalence of hypertension was higher in patients with lacunar infarct (LAC) than other subtypes. Smoking was less frequent in patients with cardioembolism (CARD). The mean infarct size was largest in patients with large artery atherosclerosis (LAA) while there were no differences in location or conversion of the infarct into hemorrhage. The proportion of the patients with milder neurological deficits at entry was higher in patients with LAC subtype. The rate of independent patients were different between subtypes: 62% in LAC, 43% in CARD, 38% in SUE, 35% in LAA at discharge ( p=0.01), and 91% in LAC, 69% in CARD, 59% in SUE, 60% in LAA at 6 months ( p<0.001). Recurrence rates were not different between groups. We conclude that risk factors, clinical imaging variables are different among ischemic stroke subtypes and that neurological status on admission and during follow-up strongly favors LAC.
We found that the sleeping position had a significant influence on apneic events and RSSP decreased the frequency of obstructive respiratory events in patients with moderate and severe disease.
A review of nasopharyngeal carcinomas (NPCs) treated in the Hacettepe University Hospitals is presented. One hundred twenty-four patients between the ages of 3 years and 72 years were managed in the period 1968-1992. Of these cases, 48 had only cranial nerve (CN) involvement on admission. The most commonly affected CNs were the VIth and the Vth, in that order. The prognostic significance of this finding is obvious, because early diagnosis and treatment is vital in a cancer patient. This study includes retrospective analysis of 124 patients with NPC. The patients were investigated with respect to clinical and radiological diagnosis and outcome. Our results also show that CN involvement in NPC usually requires careful neuro-otological examination. It is suggested that increased knowledge and understanding of the disease among neurosurgeons, neurologists and ENT surgeons would improve the prognosis of patients with NPC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
