Many aspects of the pathogenesis of acute encephalitis and acute encephalopathy have been clarified in this decade, although many unknown mechanisms remain to be elucidated. According to progress of MRI and neuroimmunological analysis and the observation of clinical findings, many new syndromes were found, which enhanced our understanding of acute encephalitis and acute encephalopathy. The pathogenesis of encephalitis is divided into infection and immune mediated mechanisms. The antibodies to neuronal surface antigens(NSA) such as NMDA receptors, leucin-rich glioma inactivated 1 (LGI1) and aquaporin 4 were demonstrated in specific encephalitis, limbic encephalitis and neuromyelitis optica. Anti-NSA antibody encephalitis should be treated by immunotherapy such as corticosteroid and plasmapheresis. Acute encephalitis with refractory repetitive partial seizures (AERRPS) is a devastating postinfectious disease in children and adults, although the pathogenesis of AERRPS is poorly understood. Influenza associated encephalopathy(IAE) is characterized by it's high incidence in Japanese children between 1 year and 5 years of age, its onset in the first or the second day of illness and its high mortality (15-30%) and morbidity (25-40%). We proposed the classification of IAE with poor prognosis from the neuroradiological findings. Four types of encephalopathy seem to be differentiated from each other, acute necrotizing encephalopathy (ANE) type, hemorrhagic shock and encephalopathy syndrome (HSES) type, acute brain swelling (ABS) type, febrile convulsive status epilepticus (FCSE) type. The notable radiological features are thalamic lesions in ANE, diffuse cerebral cortical cytotoxic edema in HSES, reversible cerebral swelling in ABS which sometimes reaches lethal brain herniation, and in FCSE type, dendritic high signal in subcortical white matter by DWI ("bright tree appearance") appears simultaneously with the later onset of repetitive focal seizure. These four types are not specific to IAE but are noticed in another encephalopathies caused by HHV6, rotavirus, etc.  相似文献

Assessment of acute phase proteins in acute ischemic stroke   总被引:6,自引:0,他引:6  
Acute phase proteins (APPs) have been implicated to play important roles during both acute and chronic inflammatory processes in different diseases including ischemic stroke. Though there are several studies showing the importance of APPs as inflammation markers in acute ischemic stroke (AIS), the time course of these proteins during acute phase of AIS is not well known. Thus, the aim of this study was to show the changes in plasma levels of six APPs (i.e., haptoglobin [Hp], ceruloplasmin [Cp], high-sensitive C-reactive protein [h-CRP], fibrinogen, complement 3 [C3] and complement 4 [C4]) during the first 10 days after acute stroke. The study group consisted of 34 female and 19 male patients (n = 53; mean age 65 +/- 12 years), who had first acute ischemic stroke (AIS). An age-matched control group (n = 53; 32 female and 21 male subjects, mean age 62 +/- 6 years) was also included. To evaluate the plasma levels of six APPs, the blood samples of patients with AIS were withdrawn on admission (day 1), and after 3, 5 and 10 days, whereas only one measurement was performed in the control group. In addition, several cerebrovascular risk factors were determined. The peak levels of APPs were higher in the AIS group than the control group (p < 0.0001). In serial measurements, the levels of h-CRP, Hp, C3 and C4 showed alterations during 10 days after AIS (p < 0.0001, p < 0.05, p < 0.0001, p < 0.0001, respectively). The alterations in levels of fibrinogen and Cp were not statistically significant (p > 0.05). After stroke, h-CRP, C3 and fibrinogen reached their highest values on the third day, Cp and C4 on the fifth day, and Hp on the tenth day. The plasma levels of h-CRP correlated positively with other five APPs studied (p < 0.05). These findings support the importance of inflammation processes after stroke. We suggest that the differences in levels of APPs could be used in predicting the outcome of stroke patients.  相似文献

Two lung transplant recipients had concomitant acute sinusitis and acute lung rejection. Antibiotics and decongestants alleviated the sinusitis, but the symptoms of cough and dyspnea as well as spirometric defects necessitated treatment of acute lung rejection. In patients with clinical evidence of acute sinusitis after lung transplantation, concomitant acute lung rejection should be suspected if dyspnea or pulmonary dysfunction is also present. This appears to be the first report of concomitant acute sinusitis and acute lung rejection.  相似文献

Epidemiology of acute lung injury and acute respiratory distress syndrome   总被引:4,自引:0,他引:4  
PURPOSE OF REVIEW: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are diseases with a significant influence in the public health. A better knowledge of their epidemiology could help to improve the outcome of these diseases. RECENT FINDINGS: Although the clinical criteria of the American-European Consensus Conference definitions for ALI and ARDS are simple, there is a risk of misclassification due to a poor reliability. Except for new emerging infectious diseases, such as severe acute respiratory syndrome, the etiology of ALI/ARDS has remained the same for several years. The only recent innovation is the hypothesis that pulmonary ARDS and extrapulmonary ARDS could be different clinical entities. In recent years, there has been a special interest in the study of genetic predisposition to development ALI/ARDS. Recent studies have estimated the incidence of these diseases to be between 15 and 34 cases per 100,000 inhabitants per year. This wide range could stem from differences in the methodology used to calculate the incidence or could be a true variation due to regional differences. Mortality rate of ALI/ARDS have remained steady for several years. Respiratory failure is the cause of the death in less than 20% of the patients. SUMMARY: The epidemiology of ALI and ARDS has some issues to improve, such as the accuracy of the clinical criteria of ALI/ARDS. Future research must to include study of genetic polymorphisms of the mediators involve in the development of ALI/ARDS. Studies to define better the population at risk are necessary to estimate better their true incidence.  相似文献

Acute coronary syndromes, including unstable angina, myocardial infarction, and sudden death, account for more than 250,000 deaths annually. They are the manifestation of a progressive atherosclerotic process, which culminates in the rupture of atherosclerotic plaques and the formation of mural thrombi. This article reviews recent and current research, which has shed light on key events and evolutionary processes leading to acute coronary syndromes. The article details the development of vulnerable plaques, factors that promote plaque rupture, and triggering events related to plaque rupture. Also discussed are sequelae of acute coronary syndromes, including Q wave and non-Q wave infarction and left ventricular remodeling.  相似文献

Biliary infections are very common intra-abdominal infections. Laparoscopic cholecystectomy for acute cholecystitis and endoscopic retrograde management of acute cholangitis play important roles in the treatment of biliary infections. Also antimicrobial therapy is nevertheless important in the overall management of biliary infections. A multidisciplinary team of physicians, including surgeons trained in laparoscopic techniques, interventional gastroenterologists, and interventional radiologists may improve outcomes of patients with biliary infections. This review focuses the clinical presentation, diagnosis, and state of the art management of acute cholecystitis and acute cholangitis.  相似文献
