We describe a 59-year-old stroke patient presented with sudden onset left side weakness and a speech disorder due to a major acute cerebral infarction in the area of the right middle cerebral artery, ...right posterior cerebral artery, and small infarctions in the area of the left middle and left posterior cerebral artery. For the previous month, the patient had been feeling weak and had no appetite. The patient had not been previously seriously ill. A chest x-ray showed a large mass in the upper zone of the right lung. Chest computed tomography scan and echocardiography were performed and revealed advanced lung cancer invading the left atrium. Spontaneous tumor embolism is a rare cause of stroke and should be considered in the differential diagnosis of stroke in a cancer patient. Also, sometimes stroke can be the first manifestation of advanced cancer.
Previous studies suggest that infarct expansion may be responsible for increased mortality after stroke onset in patients with prolonged stress hyperglycemia. Therefore, we evaluated the influence of ...prolonged stress hyperglycemia on stroke mortality in patients with and without diabetes.
For 630 stroke patients admitted to the neurological intensive care department within 24 hours of stroke onset, we correlated mean blood glucose levels (MBGL) at admission and 72 hours after admission in diabetic and non-diabetic patients with final outcome. Blood glucose levels higher then 6.1 mmol/L (121 mg/dL) were treated as hyperglycemia.
Of 630 patients (mean age 71 A+/- 6), 410 were non-diabetic (mortality, 25%) and 220 patients were diabetic (mortality, 20%). All patients who died within 28 days of hospitalization had prolonged hyperglycemia (at admission and after 72 hours, despite insulin therapy). The unadjusted relative risk of in-hospital mortality within 28 days for all stroke patients was 0.68 (95% CI, 0.14-1.9) for non-diabetic patients and 0.39 (95% CI, 0.27- 1.56) for diabetic patients. The unadjusted relative risk of in-hospital mortality within 28 days in ischemic stroke in patients with MBGL > 6.1-8.0 mmol/L (121-144 mg/dL) at admission and after 72 hours was 1.83 (95% CI, 0.41-5.5) for non-diabetic patients and 1.13 (95% CI, 0.78-4.5) for diabetic patients. Non-diabetic patients with hyperglycemia had a 1.7 times higher relative risk of in-hospital 28-day mortality than patients with diabetes.
Prolonged stress hyperglycemia in ischemic stroke patients increases the risk of in-hospital 28- day mortality, especially in non-diabetic patients.
Stroke remains the third leading cause of mortality in developed countries despite declining tendency over the past decades. As the leading cause of disability and second cause of dementia, primary ...prevention should be the main way to fight the disease, since therapy is not efficient enough. Several observations pointed to estrogen as a protective agent that may reduce stroke risk, however, studies have shown conflicting data. There is no strong evidence that hormone replacement therapy (HRT) increases stroke risk. Several studies have shown that HRT may reduce the risk of fatal stroke. Conflicting results have been found for Alzheimer's disease and HRT as well. An association between higher serum concentration of estradiol and decreased risk of cognitive decline has been found in some studies, supporting the hypothesis that estrogen concentration may play a significant role in brain protection. Having in mind results of recent randomized trials, it is suggested that HRT should not be recommended on general basis for the primary or secondary prevention of cardiovascular/cerebrovascular diseases or for primary prevention of degenerative diseases such as Alzheimer's disease. Osteoporosis, cognitive decline and climacteric symptoms that are likely to impact on quality of life, speak in favor for recommendation of HRT use. On the other side, family history of breast carcinoma, mastopathy, thromboembolism, in certain cases gallbladder disease, will discourage the commencement of HRT. Respecting the patient's preferences and having benefits and risks in mind as well as science advisory statements, individual counseling regarding HRT should be the leading concept in the healthcare of postmenopausal women.
The purpose of our study was to contribute to better understanding of cerebrospinal fluid (CSF) as a valuable biological material in the research of brain tumors within the "low T3 syndrome", and to ...discuss the role of thyroid hormones in the central nervous system in subjects with severe cerebral lesions. We studied the levels of total triiodothyronine (tT3), total thyroxine (tT4), free triiodothyronine (fT3), free thyroxine (fT4), reverse triiodothyronine (rT3) and thyrotropin (TSH) in serum, and fT3, fT4, rT3 and TSH levels in CSF of patients with brain tumor, and compared the results with control group. Study results indicated a statistically significantly higher level of rT3 in serum and CSF of brain tumor patients vs. control group (p < 0.05). The rT3/fT3 ratio was highest in CSF and serum of brain tumor patients, yielding a statistically significant difference (p < 0.05). These results could suggest higher permeability of the blood-brain barrier in brain tumor patients. We also assume that rT3, in the framework of"cerebral low T3 syndrome", is also generated through local intracerebral conversion. Disruption of this process in severe cerebral lesion can lead to increased rT3 concentrations, i.e. development of the "low T3 syndrome".
These are evidence based guidelines for the management of medical complications in patients following aneurysmal subarachnoid hemorrhage, developed and endorsed by the Croatian Society of ...Neurovascular Disorders, Croatian Society of Neurology including Section for Neurocritical Care, Croatian Neurosurgical Society, Croatian Society for Difficult Airway Management and Croatian Medical Association. They consist of recommendations for best monitoring, medical treatment and interventions based on the literature, evaluation of the results of large international clinical trials, and collective experience of the authors.
A case is reported of a 72-year-old woman who presented with severe vertigo, vomit, and mild neck and occipital pain. She had a medical history of hypertension, angina pectoris, cholelithiasis, ...gastric ulcer, pyelonephritis and periodical mild dizziness. Neuroimaging revealed right vertebral artery occlusion, right cerebellar stroke and basilar impression. The therapeutic approach chosen in our patient was conservative, with non-steroid anti-inflammatory drugs and neck collar. Although our patient's prior risk factors for stroke supported a diagnosis of vertebrobasilar stroke, it is possible that the vertebral artery occlusion was the result of changes in the atlantoaxial anatomy and that cerebellar infarction was secondary to craniocervical anomaly. Although the presence of vertebral artery occlusion, cerebellar stroke and basilar impression in our patient may have been coincidental, we suggest that patients with basilar impression and craniocervical anomalies in general may be at an increased risk of vertebrobasilar vascular disease and vertebrobasilar stroke.
These guidelines have been developed to assist the physician in making appropriate choices in work-up and treatment of patients with headaches. The specific aim of the Evidence Based Guidelines for ...Treatment of Primary Headaches--2012 Update is to provide recommendations for establishing an accurate diagnosis and choose the most appropriate therapy in the group of patients with primary headaches, based on a comprehensive review and meta-analysis of scientific evidence with regard to treatment possibilities in Croatia. These data are based on our previous Evidence Based Guidelines for Treatment of Primary Headaches published in 2005 and other recommendations and guidelines for headache treatment.
Fabry disease (Anderson-Fabry disease) is one of the most common lysosomal storage diseases (after Gaucher disease) caused by deficient activity of the α-galactosidase A (α-Gal A) enzyme, which leads ...to progressive accumulation of globotriaosylceramide in various cells, predominantly in endothelium and vascular smooth muscles, with multisystem clinical manifestations. Estimates of the incidence range from one per 40,000 to 60,000 in males, and 1:117,000 in the general population. Pain is usually the first symptom and is present in 60%-80% of affected children, as well as gastrointestinal disturbances, ophthalmologic abnormalities and hearing loss. Renal failure, hypertrophic cardiomyopathy, or stroke as the presenting symptom may also be found even as isolated symptoms of the disease. Life expectancy is reduced by approximately 20 years in males and 10-15 years in females, therefore enzyme replacement therapy should be introduced in patients of any age and either sex, who meet treatment criteria for Anderson-Fabry disease.
