Carotid endarterectomy in 39 elderly patients was carried out under local anesthesia and neuroleptic analgesia. There were no deaths within 30 days. Two patients required an intraoperative shunt because of signs of ischemic changes (aphasia, motor changes) during two-minute test cross-clamping. In two patients, transient vocal cord paresis was observed, and seven patients (18%) experienced immediate postoperative hypertension. Our results support the contention that in awake elderly patients the need for an intraoperative shunt can be accurately assessed by simple neurological monitoring. Carotid surgery under local anesthesia and neuroleptic analgesia appears to be a safe procedure, and is especially recommended for elderly patients with hypertension, diabetes mellitus or ischemic heart disease.

Relationship of types of aphasia in hemiplegics to survival, outcome of rehabilitation, activities of daily living (ADL) and pre-existing risk factors, hypertension (HT), ischemic heart disease (IHD), diabetes mellitus (DM) were studied in a group of 257 patients. The control group was a large population of CVA cases previously documented. Four main categories were considered: expressive-receptive (global), predominantly expressive (Broca), predominantly receptive (Wernicke) and predominantly amnestic (anomia) aphasias. 40% of each category were female. No clear pattern emerged concerning relationship with risk factors; however, hypertension, the factor most frequently encountered, was significantly less prevalent among expressive ahphasics, and diabetes mellitus was rare among those with the receptive pattern. For all categories, the most frequent etiology was thrombosis, the second being embolia. The oldest groups were the expressive-receptive and the predominantly receptive aphasia groups: showed the poorest rehabilitation outcome in both ADL and locomotion, and lived less time after stroke (5.8 years). Amnestic and expressive patients were younger and fared better in all other parameters; an etiology of embolia was much more frequent among the former. It can be said that patients with the expressive-receptive kind of aphasia have the worst survival and rehabilitation prognoses.

Results of carotid endarterectomy (41 operations) carried out under local anesthesia are presented. There were no deaths within 30 days. Three patients had undergone surgery with a temporary internal shunt, following signs of neurological changes (unconsciousness, aphasia, motor changes) during 1-min test cross-clamping. No neurologic deficits were observed, and only two patients (4.8%) experienced postoperative hypertension. These data support the view that simple neurological monitoring of awake patients enables accurate assessment of the need for an internal carotid shunt. Carotid endarterectomy under local anesthesia seems to be a very safe procedure. Use of this technique is especially appropriate for elderly patients with hypertension and ischemic heart disease.

On the island of Kitava, Trobriand Islands, Papua New Guinea, a subsistence lifestyle, uninfluenced by western dietary habits, is still maintained. Tubers, fruit, fish and coconut are dietary staples. Of the total population, 1816 subjects were estimated to be older than 3 years and 125 to be 60-96 years old. The frequencies of spontaneous sudden death, exertion-related chest pain, hemiparesis, aphasia and sudden imbalance were assessed by semi-structured interviews in 213 adults aged 20-96. Resting electrocardiograms (ECG's) were recorded in 119 males and 52 females. No case corresponding to stroke, sudden death or angina pectoris was described by the interviewed subjects. Minnesota Code (MC) items 1-5 occurred in 14 ECG's with no significant relation to age, gender or smoking. ST items (MC 4.2 and 4.3) were found in two females and Q items (MC 1.1.2, 1.3.2 and 1.3.3) in three males. Stroke and ischaemic heart disease appear to be absent in this population.

Medical treatment of stroke is dependent on a narrow therapeutic time window. We prospectively analyzed the influence of demographic, medical, and pathophysiologic factors on admission delay in 1,197 unselected, acute stroke patients. Twenty five percent were admitted within 3 1/2 hours, 35% within 6 hours, 50% within 14 hours, and 68% within 24 hours after stroke onset. Living alone (odds ratio [OR] 1.75, 95% CI 1.3 to 2.3) and retired working status (OR 1.61, 95% CI 1.01 to 2.54) delayed admission. A well-working social network thus seems important to early admission. The milder the stroke, the higher was the risk of delayed admission (OR 1.25 per 10 points decrease in stroke severity [Scandinavian Neurological Stroke Scale score on admission], 95% CI 1.14 to 1.36). A history of TIA increased the relative chance of early admission by odds 1.64 (95% CI 1.06 to 2.54). Other factors such as age, sex, diabetes, hypertension, ischemic heart disease, other comorbidity, previous stroke, headache, aphasia, apraxia, anosognosia, neglect, lowered consciousness, mental status (Mini-Mental State Examination) and type of stroke (hemorrhage/infarct) had no independent influence on admission time. Admission was markedly delayed in most patients. This represents a major barrier to medical treatment. Patients with the most severe strokes are admitted early, but patients with milder symptoms should also be encouraged to seek immediate admission. The observation that a history of TIA reduced admission time indicates that an increase in public awareness and knowledge may reduce delay and save precious time.

The purpose of the study was to study admission delay in patients with stroke, and to analyze the influence of demographic, medical, and pathophysiological factors on admission delay. The study was prospective and consecutive and included 1197 unselected patients admitted with acute stroke from a well-defined catchment area in Copenhagen. Only 35% were admitted within the first six hours from stroke onset, and 50% of the patients were admitted later than 14 hours from stroke onset. Living alone (OR 1.75, 95% CI 1.3 to 2.3) and retired working status (OR 1.6, 95% CI 1.01 to 1.54) delayed admission. A well-functioning social network thus seems important to early admission. The milder the stroke, the higher was the risk of delayed admission (OR 1.25 per 10 points increase in stroke severity (Scandinavian Neurological Stroke Scale on admission), 95% CI 1.06 to 2.54. Other factors such as age, sex, diabetes, hypertension, ischaemic heart disease, other comorbidity, previous stroke, headache, aphasia, apraxia, anosognosia, neglect, lowered consciousness, mental status, and type of stroke had no independent influence on admission time. However, a history of TIA increased the chance of early admission by odds 1.64 (95% CI 1.01 to 2.54), indicating that an increase in public awareness and knowledge may reduce delay and save precious time.

The aim of this study was to describe the clinical characteristics of atypical lacunar syndrome (ALS) based on data collected from a prospective acute stroke registry. In total, 2500 acute stroke patients were included in a hospital based prospective stroke registry over a 12 year period, of whom 39 were identified as having ALS and radiologically proven (by computed tomography or magnetic resonance imaging) lacunes. ALS accounted for 1.8% of all acute stroke patients, 2.1% of acute ischaemic stroke, and 6.8% of lacunar syndromes. ALS included dysarthria facial paresis (n = 12) or isolate dysarthria (n = 9), isolated hemiataxia (n = 4), pure motor hemiparesis with transient internuclear ophthalmoplegia (n = 4), pure motor hemiparesis with transient subcortical aphasia (n = 3), unilateral (n = 2) or bilateral (n = 3) paramedian thalamic infarct syndrome, and hemichorea hemiballismus (n = 2). Atypical lacunar syndromes were due to small vessel disease in 96% of patients. Atherothrombotic infarction occurred in one patient and cardioembolic infarct in another, both presenting pure dysarthria. Outcome was good (in hospital mortality 0%, symptom free at discharge 28.2%). After multivariate analysis, the variables of speech disturbances, nausea/vomiting, ischaemic heart disease, and sensory symptoms were found to be significantly associated with ALS. In conclusion, atypical lacunar syndrome is an infrequent stroke subtype (one of each 14 lacunar strokes). ALS occurred in 6.8% of lacunar strokes. Isolated dysarthria or dysarthria facial paresis were the most frequent presenting forms. The prognosis of this infrequent non-classic lacunar syndrome is good.

In this article, the authors have gathered data from epidemiological, observational, case-control and cohort studies to evaluate the differences between men and women in terms of ischemic events, mainly stroke. The authors are highlighting the differences that exist between men and women and play a role in terms of social diversities, and the pathophysiological differences that may be responsible at least in part for ischemic events. Studies show that male stroke patients are more likely to have a history of ischemic heart disease, smoking and alcohol consumption, whereas female stroke patients suffer from ischemic events at an older age, are more likely to have hypertension and atrial fibrillation. Women are more likely to arrive to an emergency room in a comatose state, with paralysis, aphasia, swallowing problems and urinary incontinence, which all indicates a more severe stroke. Also, women suffer from a higher level of disability than men, even though their survival rates are the same. Even though clear guidelines for the treatment of stroke exist, there are still differences in both diagnostic procedures and discharge destination between male and female patients.
