Comment on “Posterior reversible encephalopathy syndrome in a patient with metastatic breast cancer: A case report”

Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic encephalopathic state, manifesting clinical symptoms of headache, altered consciousness, visual disturbances, and seizures. Although several diseases have been identified as causative of PRES, the underlying mechanism remains unclear. Song et al recently published “Posterior reversible encephalopathy syndrome (PRES) in a patient with metastatic breast cancer: A case report“ in the World Journal of Clinical Cases, highlighting and discussing the role of hypercalcemia in PRES as related to uncontrolled hypertension. To build upon this case description, we provide further insight into the possible underlying mechanisms of PRES through this commentary.

Does Sleep Apnea Affect the Outcome of Stroke Patients?

BACKGROUND

Sleep apnea is described as an isolated risk factor for stroke or recurrent stroke which could be cause of death. In our study, the aim was to determine whether sleep apnea affects the outcome of stroke patients.

SUBJECTS AND METHODS

This is a prospective study in which a group of 110 patients in the acute phase of a stroke was evaluated sleep apnea. Acute stroke has been diagnosed either by computed tomography and magnetic resonance imaging of the brain. There was no significant difference in patient's age with or without sleep apnea neither in men nor women. Neurological, neuropsychiatric, pulmonary test were performed in all patients at five different time periods. In these time periods, all patients were evaluated: Glasgow scale, The American National Institutes of Health Scale Assessment, Mini Mental Test, The Sleep and snoring Questionnaire Test, The Berlin Questionnaire Test, The Epworth Sleepiness Scale, The Stanford Sleepiness Scale and The general sleep questionnaire.

RESULTS

One year after the onset of stroke, 91 (82.7%) of 110 patients with apnea survived. The survival rate of patients with sleep apnea is significantly lower than without sleep apnea (p=0.01). In men with apnea, the survival rate was significantly lower in patients without apnea (p=0.004). The largest number of survivors of apnea had diabetes mellitus, followed by survival of patients with heart disease, body mass index >29 kg/m² and hypertension, with hyperlipoproteinemia and smoking. The highest number of survivors without apnea was body mass index >29 kg/m², followed by survival of patients with hyperlipoproteinemia, heart disease, hypertension, smoking, and diabetes mellitus.

CONCLUSION

Patients with sleep apnea have a significant correlation in survival rates compared with sexually and age-matched subjects, associated with concomitant risk factors such as hypertension, body mass index, and smoking.

Neurobrucellosis and cerebral venous sinus thrombosis: a case report

OBJECTIVES

To present a case of co-occurrence of neurobrucellosis and cerebral venous sinus thrombosis.

METHODS

Case report.

CLINICAL PRESENTATION

 We presented 49-year-old Caucasian domicile female-farmer with a history of headache, weakness, and vomiting for a period of three months. Also, she had significant papilledema. We diagnosed rare co-morbidity of neurobrucellosis (confirmed after ELISA-test in serum samples and CSF analysis of pleocytosis/increase in protein/decrease in glucose level) in the setting of cerebral venous thrombosis developed in left sigmoid/left transverse sinus (confirmed after MRV of brain). Favorable outcome was achieved by applying protracted polymicrobial antibiotic therapy and heparin.

DISCUSSION

It may be challenging to diagnose neurobrucellosis, especially in patients with atypical presentation and abortive clinical forms. The co-morbidity of neurobrucellosis and cerebral venous sinus thrombosis is uncommon. However, it provides a possibility of brucella-colonization in cerebral venous sinuses as a potential hidden link between them.

CONCLUSION

Patients with severe and persistent headache, as well as other neurological symptoms/signs should be considered for neurobrucellosis in endemic, but also in brucella non-endemic regions due to migrations. According to literature survey, this co-occurrence of neurobrucellosis and cerebral venous sinus thrombosis is third one reported from Europe.

Falls in hospitalized acute stroke patients

THE AIM of this study was to analyze the fall frequency and some of its characteristics in hospitalized acute stroke patients.

PATIENTS AND METHODS

It was analyzed 1809 acute stroke patients hospitalized at the Department of Neurology in period of one year. A fall was defined as any unplanned "touch to the floor" of any part of a patient's body, excluding the feet.

RESULTS

Out of 1809 acute stroke patients, 1544 (85.35%) had cerebral infarction (CI) and 265 (14.65%) intracerebral hemorrhage (IH). In group of patients that fell (61/3.3%), 49 (80.33%) had infarction and 12 (19.67%) (p = 0.25) had hemorrhage. Out of 61 patients that fell, 42 (68.86%) suffered from impaired spatial orientation and 47 (77.05) were aphasic. The neurological deficit, impairments of spatial orientation and presents of aphasia were highly correlated with falls (p < 0.001). The most frequent falls occurred by night night (38 or 62.29%) and in the first five days of hospitalization (44 or 72%). In most cases (52%) the falls caused minor injuries like contusion and lacerations of skin and did not require special medical treatment.

CONCLUSION

Hospitalized acute stroke patients have no high risk of falling (3.3%), and the incidence of serious injury is low. The falls are more frequent in the first five days of hospitalization (72%) and occur mostly during the night (62.29%). Severity of neurological deficit, impaired spatial orientation and aphasia are highly correlated with falls.

Sex differences in patients with acute ischemic stroke in Tuzla region, Bosnia and Herzegovina

Although many aspects of stroke are similar at both sexes, however, there are some differences and characteristics as well. The aim of this study was to analyze sex differences in patients with acute ischemic stroke (IS) regarding to risk factors, subtypes, stroke severity and outcome. From January 1st 2001 to December 31st 2005 at the Department of Neurology Tuzla 2833 patients were admitted with acute ischemic stroke (IS). We were analyzed risk factors, subtypes, stroke severity (Scandinavian Stroke Scale), and thirty-day outcome. There were 1484 (52.3%) female, and they were older than male (67.8 +/- 10.6 vs. 65.7 +/- 10.5, p<0.0001). Hypertension (78% vs. 67%, p<0.0001), heart diseases (50% vs. 45%, p=0.009), atrial fibrillation (22% vs. 14%, p<0.0001) and diabetes mellitus (33% vs. 21%, p<0.0001) were frequently in female, while smoking (45% vs. 14%) and alcohol overuse (18% vs. 0,6%) in male (p<0.0001). Atherothrombotic type of ischemic stroke was frequently in male (37.4% vs. 31.6%, p=0.0013) and cardioembolic in female (21.7% vs. 15.5%, p<0.0001). At admission female had lower SS (SS 31.0 +/- 15 vs. 34.0 +/- 15, p<0.0001). Thirty-day mortality was significantly higher in female (23.3% vs. 18.4%, p=0.0015), and favourable outcome within one month (Rankin Scale Collapse

Five-Year Survival After First-Ever Stroke

The aim of the study was to analyze the 5-year survival after first-ever ischemic stroke and intracerebral hemorrhage. In this study 836 patients were analyzed with a first-ever stroke admitted at the Department of Neurology Tuzla, Bosnia and Herzegovina, from January 1(st) 1997 to December 31(st) 1998. Of these 613 (73,3%) were ischemic strokes and 223 intracerebral hemorrhages (26,7%) Subarachnoid hemorrhages were excluded. After hospitalization surviving patients examined periodically, and a final examination was performed 5 years after the stroke. Overall, case-fatility at the first month was 36% (301/836) and the mortality rate was significantly higher in the patients with intracerebral hemorrhage (58,3% vs. 27,9%, p<0,0001). The first year survived 60% patients with ischemic stroke, and 38% with intracerebral hemorrhage. After 5 years, 188 (31%) patients with ischemic stroke and 53 (24%) with intracerebral hemorrhage were alive (p=0,5), and the cumulative survival rate for the entire study was 29%. Among 30-day survivors (n=535) surviving rate after 5 years was significantly higher in patients with intracerebral hemorrhage (57% vs. 42,5%, p=0,01). The survival rate was the highest for those 50 years and younger (57%), and the lowest for those aged over 70 years (9%). Predictors of 5-year mortality were older age and hypertension for both types of stroke, heart diseases for ischemic stroke and diabetes for intracerebral hemorrhage. Long-term survival after first-ever ischemic stroke and intracerebral hemorrhage is similar. However, among 30-day survivors the 5-year survival is better in patients with intracerebral hemorrhage.
