Prognostic implications of the motor symptoms of Parkinson's disease with respect to clinical,computertomographic and psychometric parameters

Summary Forty-four Parkinson patients (19 patients of the rigid-akinetic type, 13, of the rigid-akinetic-tremor type, and 12, of the tremor type) were included in a study in order to analyse correlations of the expression of the motor symptoms tremor, rigidity, akinesia, with other clinical parameters, computertomographic aspect of brain atrophy and psychometrically assessed cognitive parameters. Rigidity and akinesia are significantly positively correlated with the severity of motor dysability, stage of the disease, and brain atrophy, as is akinesia with a history of pharmacotoxic psychosis. Tremor is significantly negatively correlated with motor dysability, stage of the disease, and history of pharmacotoxic psychosis. Akinesia is correlated with visuomotor dysfunction (tested with Bender Gestalt Test) and rigidity with the depression score (Zung scale). The tremor type is favorable, the rigid-akinetic type unfavorable with respect to motor disability and psychosis.     

Acute lymphoblastic leukemia in children: correlation of musculoskeletal manifestations and immunophenotypes

Purpose Studies on musculoskeletal manifestations (MSM) of childhood acute lymphoblastic leukemia (ALL) have yielded variable findings with regard to their clinical impact. We investigated the significance for differential diagnosis, treatment and outcome of musculoskeletal complaints as presenting symptoms of ALL, and their correlation with leukemia immunophenotypes, for which data is lacking. Methods Data on 783 children in the national study for childhood ALL between 1984 and 2003 were reviewed retrospectively. Statistical analysis examined possible relationships between MSM at the time of diagnosis and demographic and clinical data, biological features of leukemia (peripheral blood counts, immunophenotype and main cytogenetic aberration), response to initial prednisone treatment, and outcome. Results Of 765 children with data on orthopaedic complaints, 240 presented with MSM (31.4%). Among these children, B cell precursor (BCP) was much more common (209/576, 36.3%) than T cell ALL (25/176, 14.2%). Patients with MSM had lower white blood cell counts (WBC) (median of 9 vs. 20 × 10⁹/L, P < 0.001) and percentage of blast cells in the peripheral blood at diagnosis compared to those without (median of 27 vs. 53%, P < 0.001). Hepatomegaly and splenomegaly were less common in MSM group (67 vs. 53% <3 cm, P < 0.001, and 63 vs. 50% <3 cm, P < 0.001, respectively). Poor response to initial treatment with prednisone was recorded in 7.1% of patients with MSM versus 11.5% of those without (P = 0.086). The analysis revealed no independent effect of MSM on event-free survival (EFS), after correcting for differences in EFS related to immunophenotype or initial WBC. Conclusions MSM occur mostly in children with BCP ALL who present with less involvement of extramedullary organs, low peripheral blood blasts and white blood cells counts. These findings highlight the importance of including ALL in the differential diagnosis of MSM even in the presence of an apparently normal peripheral blood count. Our study also suggests that MSM are caused by leukemic cells with enhanced biological propensity to remain relatively confined within the intramedullary bone-marrow space.     

初诊高血压病患者心理、个性和行为特征对控烟效果的影响

目的 观察初诊高血压病患者心理、个性和行为特征对控烟效果的影响.方法 对84例初诊高血压病吸烟患者行控烟治疗,连续3个月后评价控烟效果,并采用A型行为问卷、艾森克个性问卷(EPQ)及症状自评量表(SCL-90)对其进行测评.结果 控烟效果佳者38例,占45.24%;控烟效果差者46例,占54.76%.前者A型行为问卷、EPQ问卷(除外内外向性维度)评分均显著优于后者(P＜0.05,P＜0.01);SCL-90除偏执、阴性项目外,其余项目评分均显著优于后者(P＜0.05,P＜0.01).结论 A型行为类型、神经质和精神病性人格特征及负性情绪是影响控烟效果的重要因素,对此类患者实施控烟的同时予以针对性心理干预可望获得事半功倍的效果.     

乳腺癌新辅助化疗后动态增强MRI表现与病理反应性相关性研究

目的探讨乳腺癌新辅助化疗后动态增强MRI（DCE—MRI）表现的形态学和时间信号强度曲线（TIC）类型与病理学反应性的关系。方法45例乳腺癌患者经新辅助化疗结束后行乳腺DCE—MR检查及手术治疗。应用AW4．2图像工作站观察残余肿瘤强化的形态和TIC类型（共3型）。由病理科医师对乳腺癌化疗后手术标本的病理反应性进行评估，分为1～5级，5级为病理完全缓解，4级和5级为组织学显著反应。分析病理反应性级别与DCE—MRI残余强化的TIC类型、形态的关系，统计方法采用精确概率法。结果45例中病理反应性5级7例，4级16例，3级16例，1和2级共6例。20例I型曲线中组织学显著反应者占70．0％（14／20），而6例Ⅲ型曲线均为组织学反应不显著者。TIC类型在不同的病理反应级别分布差异有统计学意义（P=0．001）。组织学显著反应且有残余强化者共18例，其中非肿块性强化11例。残余强化的肿块（非肿块）形态表现在不同病理反应性分级中分布差异有统计学意义（P=0．012）。结论乳腺癌新辅助化疗后DCE—MRI的形态及血液动力学表现特点与化疗后病理反应性相关。非肿块性强化和I型TIC与组织学显著反应有关。

Lipid peroxidation in several brain regions during development of post-stress depressions in rats with different strategies of adaptive behavior

Lipid peroxidation in the brain cortex, striatum, hippocampus, and hypothalamus of rats of the KLA and KHA lines which were distinguished by their strategies of adaptive behavior was investigated following emotional-painful stress. Significant long-term changes in lipid peroxidation were shown to occur in the brain. These had a phase character and depended on the behavioral characteristics of the animals. The investigated brain regions were characterized by different reactions of lipid peroxidation to the stress. The induced depressive-like states (on the 21st day after the stress) in rats of the KLA and KHA lines were distinguished by the largest changes in lipid peroxidation in the striatum and hypothalamus and in the striatum and hippocampus, respectively. One could conclude on the basis of these results that both identical and different mechanisms of formation and development of depression existed in the animals with different behavioral strategies.     

Time to REST: epidemiology and burden

Restless legs syndrome (RLS) is a neurological disorder characterized by a compelling urge to move, accompanied by disturbing sensations within the legs. It is now recognized that RLS is a common condition that has a substantial impact on sleep, daily activities and quality of life. Recent data from the REST (RLS Epidemiology, Symptoms, and Treatment) general population study show that symptoms of RLS are present in approximately 7% of the general population, and that 2–3% experience moderate or severe symptoms at least twice a week. Amongst this RLS cohort, approximately 88% reported sensory disturbances and 76% reported sleep-related symptoms. These symptoms had a marked effect on everyday life, with up to 50% of the RLS cohort reporting disruption of everyday activities or personal relationships. Sleep disturbances in turn lead to impaired daytime functioning. RLS is associated with a significant impairment of quality of life, comparable with that seen in chronic medical conditions such as diabetes or depression. Given the significant burden of morbidity associated with RLS, there is a strong case for treatment in patients with troublesome symptoms.     

Hypertrophy of medial globus pallidus and substantia nigra reticulata in 6‐hydroxydopamine‐lesioned rats treated with L‐DOPA: Implication for L‐DOPA‐induced dyskinesia in Parkinson's disease

The medial globus pallidus plays a crucial role in generation of L‐DOPA‐induced dyskinesia in patients with Parkinson's disease. The 6‐hydroxydopamine‐lesioned rat exhibiting behavioral sensitization to L‐DOPA is one useful animal model for examining L‐DOPA‐induced dyskinesia. To determine neuropathological abnormality responsible for behavioral sensitization, the medial globus pallidus and the substantia nigra reticulata in 6‐hydroxydopamine‐lesioned rats treated with L‐DOPA were examined. Intermittent L‐DOPA treatment induced hypertrophy of the lesioned‐side of medial globus pallidus and substantia nigra reticulata of 6‐hydroxydopamine‐lesioned rats with behavioral sensitization to L‐DOPA. Additionally, coadministration of a 5‐HT_1A receptor agonist, 8‐hydroxy‐2(di‐n‐propylamino)tetralin with L‐DOPA, alleviated the hypertrophy with improvement of the behavioral sensitization. These results suggest that hypertrophy of the medial globus pallidus and substantia nigra reticulata is associated with induction of behavioral sensitization to L‐DOPA in 6‐hydroxydopamine‐lesioned rats. Therefore, neuropathological changes corresponding to hypertrophy might underlie L‐DOPA‐induced dyskinesia in patients with Parkinson's disease.
