外伤性截瘫合并耳聋11例临床分析

初步分析了11例外伤性截瘫合并耳聋患者,指出外伤性截瘫多有慢性肾功能不全、肾性贫血等并发症。这些并发症对耳聋的发生有一定的影响,但长时间或反复使用耳毒性药物是一个不可忽视的重要因素。作者对此提出了预防耳聋的一些具体措施,可供临床参考或借鉴。

The quality of acute stroke units on a nation-wide level: the Austrian Stroke Registry for acute stroke units

Concepts for stroke units that cover the acute phase vary. Therefore, the network of acute stroke units that is being set up in Austria in a uniform way is of general interest. This nationwide network has been established in accordance to evidence-based recommendations and prespecified criteria for available resources. The location for such a unit follows a maximum of 90-min isochrones (transport time) to the hospital. The quality of the network is currently documented and the results are reported. A nationwide stroke registry was prospectively performed on 15 stroke units that were already functional in this network. The aim was to document the quality performance of Austrian stroke units, focusing on rapid admissions, ready availability of investigations and therapies performed. Outcome measures were Barthel scale, Rankin score and percentages of complications. Between August 1998 and December 2000, 2,313 patients with ischemic stroke or with primary intracerebral hemorrhage admitted to an Austrian stroke unit within 24 h after onset of symptoms were prospectively included. Forty-three percent of the patients had a moderate or severe stroke. Fifty-seven percent of all patients were admitted to the stroke unit within 3 h after the onset of symptoms. Twenty-seven percent of these patients were brought in by ambulance accompanied by an emergency physician. Two percent of patients were admitted by helicopter. Fifty-four percent of patients had their first brain imaging within 30 min after admission, another 26% within 3 h. Intravenous thrombolysis was performed in 4.1% of patients. The overall stroke-unit mortality was about 6.8% and mortality at 3 months was 12.9%. The outcome at 3 months showed a modified Rankin Scale score of 0 or 1 in 47% of patients, denoting none or mild impairment. This network of acute stroke units is highly efficient in terms of rapid admissions, short intrahospital delays, as well as rapid use of readily available investigations. Stroke units seem to be well accepted by the general public and the medical community because our data show that all types of strokes are treated in Austrian stroke units, including severe strokes. The total number of concurrently treated acute strokes in other institutions across Austria is not known and no formal comparison with other systems of hospitalized care was undertaken, therefore further research is necessary.     

Practice protocol for the examination of specimens removed from patients with carcinoma of the urinary bladder, ureter, renal pelvis, and urethra

This article details a practice protocol for the examination and reporting of specimens removed from patients with carcinoma of the urinary bladder, ureter, renal pelvis, or urethra. It was created by a multidisciplinary task force of pathologists and oncologists established by the Cancer Committee of the College of American Pathologists. Documentation for the protocol was obtained from the previously published protocol, the medical literature, personal experience, and consultation with colleagues. After creation and review by the task force, the protocol was sent to 1000 randomly selected practicing pathologists as a survey. Their comments and suggestions were addressed in the final version. The protocol was approved by the Board of Governors of the College of American Pathologists.     

复方白术颗粒对大鼠缺血脑组织超微结构的影响

目的：观察复方白术颗粒对大鼠急性缺血脑组织超微结构的影响。方法：采用单侧大脑中动脉热凝闭法建立大鼠急性脑缺血模型，设立中药组、模型组和对照组，中药组给予复方白术颗粒灌胃，模型组只造模不用中药，对照组只开颅不闭塞脑动脉，电镜观察3组脑组织超微结构。结果：中药组大鼠脑缺血区神经元、神经突触、神经髓鞘、神经轴索及血脑屏障的损伤程度，血脑屏障周边星形细胞足突、神经元胞浆及神经轴突、树突水肿程度均轻于模型组。结论：复方白术颗粒能减轻大鼠急性缺血脑组织超微结构的损伤和水肿。     

2018症状性动脉粥样硬化性非急性颅内大动脉闭塞血管内治疗中国专家共识

正约10%的缺血性卒中是由颅内动脉粥样硬化性严重狭窄或闭塞所致,这类疾病可统称为颅内大血管闭塞性疾病(largeartery occlusive disease,LAOD),其卒中年复发风险为3.6%～22.0%,在存在血流动力学障碍的患者,年卒中风险更高。颅内动脉狭窄为50%～69%的     

Neurodevelopmental Outcomes in Children With Congenital Heart Disease: Evaluation and Management: A Scientific Statement From the American Heart Association

BACKGROUND: The goal of this statement was to review the available literature on surveillance, screening, evaluation, and management strategies and put forward a scientific statement that would comprehensively review the literature and create recommendations to optimize neurodevelopmental outcome in the pediatric congenital heart disease (CHD) population. METHODS AND RESULTS: A writing group appointed by the American Heart Association and American Academy of Pediatrics reviewed the available literature addressing developmental disorder and disability and developmental delay in the CHD population, with specific attention given to surveillance, screening, evaluation, and management strategies. MEDLINE and Google Scholar database searches from 1966 to 2011 were performed for English-language articles cross-referencing CHD with pertinent search terms. The reference lists of identified articles were also searched. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. A management algorithm was devised that stratified children with CHD on the basis of established risk factors. For those deemed to be at high risk for developmental disorder or disabilities or for developmental delay, formal, periodic developmental and medical evaluations are recommended. A CHD algorithm for surveillance, screening, evaluation, reevaluation, and management of developmental disorder or disability has been constructed to serve as a supplement to the 2006 American Academy of Pediatrics statement on developmental surveillance and screening. The proposed algorithm is designed to be carried out within the context of the medical home. This scientific statement is meant for medical providers within the medical home who care for patients with CHD. CONCLUSIONS: Children with CHD are at increased risk of developmental disorder or disabilities or developmental delay. Periodic developmental surveillance, screening, evaluation, and reevaluation throughout childhood may enhance identification of significant deficits, allowing for appropriate therapies and education to enhance later academic, behavioral, psychosocial, and adaptive functioning.
