Management of pediatric pontine gliomas

We present 36 consecutive patients with intrinsic glioma of the pons. Tumors with exophytic expansion were excluded. There were 16 females and 20 males, ranging in age from 2 to 13 years, median 6 years. The most common presenting symptoms were cranial nerve dysfunction. unsteadiness of gait, and hemiparesis. Computed tomography (CT) showed a hypodense (17/21) or isodense (4/21) expansion of the pons. Five tumors had areas of contrast enhancement. Following information about prognosis and possible types of management, parents decided for or against radiation therapy: twentyfour children underwent irradiation and 12 did not. Median survival among children receiving a full course of irradiation was 280 days, compared to 140 days in an equivalent group of non-irradiated children. Hemiparesis presenting without cranial nerve symptoms and contrast enhancement on CT scan were poor prognostic factors, whereas sex, age, and duration of symptoms at diagnosis were unrelated to prognosis.

聋幼儿情绪状态对认知发展的影响

为促进聋幼儿各方面的正常发展，使其早日回归主流社会，我们对聋幼儿进行了认知和情绪表现的研究。通过问卷调查、观察和实验研究得知，聋幼儿的认知发展和良好情绪的培养是分不开的，认知内容适中有利于聋幼儿良好情绪的培养，而良好积极的情绪又可促进聋幼儿认知的发展。对此，我们实验并总结了培养聋幼儿积极情绪和促进认知发展的方法。     

Predictive value of clinical characteristics for 'benign' multiple sclerosis

We studied a cohort of 496 patients who had multiple sclerosis (MS) for at least 10 years. Ten years after disease onset, 151 had benign MS defined as an Extended Disability Status Scale (EDSS) ≤3. Between benign and non-benign patients we compared gender, age at clinical onset, relapsing–remitting or primary progressive, symptoms at onset, recovery from first relapse, time between first and second relapse, number of relapses in the first 5 years, use of immunomodulatory drugs, and EDSS scores at 2, 5 and 10 years. A multivariate regression analysis showed that a relapsing–remitting course, a low EDSS score at 5 years, and a low number of relapses in the first 5 years were predictive for benign MS at 10 years. Other factors had no additional value. Thirty-five of the 51 patients (69%) with benign MS at 10 years were still benign at 20 years. A low 10-year EDSS score was the only clinical variable associated with a benign course at 20 years. Our results suggest that within the first 5 years from onset it is not possible to predict a benign course. Disease course, EDSS score and relapse rate at 5 years are predictors for benign MS at 10 years.     

食管癌三维适形后程加速超分割放射治疗的疗效分析

目的评价三维适形后程加速超分割放射治疗食管癌的疗效及放疗反应、并发症。方法2002年2月至2004年5月,71例食管鳞癌随机分成两组,三维适形后程加速超分割组36例,食管病变上下外约4cm,前后、左右外约0.5~1cm作为PTV1,每次2GY,每周5次,DT40GY后,病变上下外约2cm,前后、左右外约0.5~1cm作为PTV2,每日2次,每次1.5GY,间隔4~6小时,总疗程6周,总剂量67GY/38次。非三维适形后程加速超分割组35例,时间、剂量、分割方式同适形组。所有病例均采用8MV-X外照射。结果1、2、3年的生存率和原发肿瘤的局控率,与非适形后程加速超分割比较,适形组明显提高,分别为88.9%、75%、63.9%比68.6%、51.4%、40%和86.1%、72.2%、58.3%比65.7%、48.5%、34.3%。适形组的急性放射反应明显低于非适形后程加速超分割组,两组有显著差别。结论本研究的初步结果表明食管癌适形后程加速超分割放射治疗的疗效优于非适形后程加速超分割组。     

Ambulatory monitoring of ultraviolet erythema in photosensitive subjects

Little is known about whether patients with photosensitive disorders exhibit a different ultraviolet erythema time course from subjects with a normal response to sunlight. We have described the application of an instrument for ambulatory monitoring of the development of ultraviolet erythema by a reflectance method in a group of patients with chronic actinic dermatitis (CAD) and in a group of normal subjects. Investigations of the time course have been reported previously but the techniques used relied upon manual measurement. Consequently sampling frequencies have been considerably lower than the one-minute sample rate used here. We have not demonstrated any difference in the rate at which erythema develops and peaks between patients with CAD and subjects with a normal response to sunlight.

The basis for treatment in multiple sclerosis

Contemporary licensed treatments for multiple sclerosis fail to provide a solution for the disease because their effects are limited to a modest reduction in the frequency of new episodes. They do not reduce disability or materially influence the progressive phase of the disease. A contemporary strategy for management requires a more detailed analysis of the separate contributions to the clinical features and overall course made by inflammation, axonal injury, compensatory mechanisms, and remyelination. From this formulation emerges the need either for early and fully effective suppression of the inflammatory response, limiting the damage to all components of the axon-glial unit; or the development of strategies for axonal and myelin repair that solve the issues of controlled differentiation, delivery and timing of these cell and growth factor-based interventions.
