Outcome of intracerebral hemorrhage: clinical and CT findings in 326 patients

Clinical symptoms and findings in cranial computed tomography (CT) were evaluated in 326 patients with intracerebral hemorrhage (ICH). Localizations of ICH were the lobes (n = 254), the basal ganglia (n = 46), the pons and brain stem (n = 13) and the cerebellum (n = 8). Multiple hematomas were present in nine patients. An initial coma (n = 225) was most frequent in ICH of the pons (n = 7), cerebellum (n = 6), and the frontal (n = 71) and temporal (n = 66) lobes. Epileptic seizures (n = 70) were most common in hematomas of the frontal (n = 24), temporal (n = 19) and parietal (n = 12) lobes and the basal ganglia (n = 6). A history of hypertension was given in 140 patients; 119 of these had an ICH with a size of ≥3 cm. Mortality (n = 162) was high with ICH in the pons and brain stem (10 out of 13), in the frontal (54 out of 98) and parietal (32 out of 58) lobes and the basal ganglia (n = 23). A size of the ICH of 3 cm or more in cranial CT and an associated ventricular hemorrhage were associated with a bad outcome. An initial disturbance of consciousness was the only reliable clinical predictor of outcome (chi-square, p < 0.001). Katamnestic evaluation of 66 of the 164 survivors after 5.2 years revealed seizures in 20 patients and mild neurological deficits in 41. Another 14 patients were partially, and nine totally dependent Nineteen patients had died in between; there was only one death attributable to another ICH.

五种螯合剂对大鼠体内微量元素影响的观察

观察了５种常用螯合剂对大鼠体内微量元素排出量、组织分布的变化。结果表明，５种螯合剂可不同程度地增加机体必需微量元素Ｚｎ、Ｃｕ、Ｍｇ和Ｃａ经尿液排出量。ＥＤＴＡ和ＤＴＰＡ的影响尤为明显。ＥＤＴＡ和ＤＴＰＡ可使Ｚｎ经尿液的排出量增加１６－５２倍，ＤＴＰＡ使肝脏Ｚｎ含量减少１５．９％（Ｐ〈０．０５），肝脏Ｃｕ含量下降６０％（Ｐ〈０．０５）。ＥＤＴＡ和ＤＴＰＡ注射后，肾中Ｚｎ含量明显增高，相当对照大鼠３．

Black-fly assemblage distribution patterns in streams in disturbed areas in southern Brazil

Black flies (Simuliidae) are considered to be pests in rural and in some urban areas in the south of Brazil due to the bites of females. Little information exists on the factors that contribute to Simuliidae distribution in these areas. We sampled 39 streams in the state of Rio Grande do Sul in September 2004 to address ecological aspects. Of the 18 species collected, those that occurred in more than 50% of the streams were: Simulium subnigrum Lutz 1910, Simulium pertinax Kollar 1882, Simulium subpallidum Lutz 1910 and Simulium incrustatum Lutz 1910. Species richness was not influenced by any of the environmental or geographical variables considered, and there was no pattern of species co-occurrence, corroborating the hypothesis of a stochastic distribution of the Simuliidae assemblage. When analyzed individually, only three of seven species with occurrence frequency >30% were related to any of the variables measured. The probabilities of occurrence of Simulium jujuyense Paterson & Shannon 1927 and S. pertinax were higher in streams with high values of water pH and electrical conductivity, whereas the opposite was observed for S. incrustatum. Therefore, due to stochastic distribution, the population studies of Simuliidae are more suitable for predicting the occurrence of species in rural areas than are studies of assemblages.     

The application of the Chinese version of the Body Image Disturbance Questionnaire in patients with systemic lupus erythematosus

This study aimed to translate the Body Image Disturbance Questionnaire (BIDQ) into Chinese and evaluate its reliability and validity in a sample of patients with systemic lupus erythematosus (SLE).Following the translation and revision of the Chinese version of the BIDQ, 169 patients with SLE were chosen as respondents to test the questionnaire''s reliability and validity. We tested the content''s validity through expert group evaluation. It is structural validity was examined through exploratory factor analysis and confirmatory factor analysis, and reliability was evaluated using Cronbach''s α and test-retest reliability.The Chinese version of the BIDQ showed a content validity of .92. A two-factor structure was revealed by exploratory factor analysis, which explained 67.83% of the variance and proved by confirmatory factor analysis. Its overall Cronbach''s α was .82 (P < .001), and the Cronbach''s α for each item ranged from .76 to .83. The test-retest reliability was .82, with the Cronbach''s α for each item ranging from .76 to .84.Thus, adequate reliability and validity of the Chinese version of the BIDQ were demonstrated for use in patients with SLE.

Validation of the Sleep Disturbance Scale for Children and prevalence of parent-reported sleep disorder symptoms in Chinese children

ObjectiveTo translate and validate the Sleep Disturbance Scale for Children (SDSC), a promising questionnaire for use among children in epidemiological studies, in Chinese children.MethodsIn total, 3525 children aged 5–16 years were randomly selected from five primary schools in Shenyang. Internal consistency, reliability and factor analyses were undertaken to assess the construct validity of the SDSC.ResultsInternal consistency indicated adequate reliability (Cronbach’s α = 0.81). Factor analytic results indicated a six-factor solution (ie, six types of sleep disorder) based on parent-reported sleep disorder symptoms. The mean total score of the SDSC was 39.28 ± 7.83 and 156 (4.43%) children were identified as suffering from parent-reported sleep disorder. The prevalence for each sleep type disorder ranged from 3.46% to 6.30% with the highest for sleep hyperhidrosis (SHY) and the lowest for disorders of initiating and maintaining sleep. Significant differences were found between boys and girls in the prevalence of sleep breathing disorders (6.51% vs 3.72%), SHY (8.62% vs 4.00%) and parent-reported sleep disorders (5.19% vs 3.67%).ConclusionsThe SDSC is reliable and useful in screening for parent-reported sleep disorders in Chinese children. Compared with other countries, parent-reported sleep disorders among Chinese elementary school children were at a relatively low level of prevalence.
