摘要:背景 非器质性视力丧失(novl)患者会占用大量的门诊时间,临床医生往往需要进行昂贵而漫长的检查以确保诊断正确.儿童的情况尤其如此.方法 回顾性审查了 30 名儿童(18 名女孩,12 名男孩)的病例记录,他们的主诉是视力受损,诊断为非器质性视力损失.这一数字占本单位儿科新转诊病例的 1%.相关症状包括头痛,眶周疼痛,复视,畏光和怕光.5 名患者出现视野缺损,1 名儿童出现近反射痉挛.结果 治疗包括安抚,所有病例的视功能均恢复正常.三名患儿被转诊至其他医疗机构.所有心理物理学,电生理学和神经放射学检查结果均为阴性.结论 我们的研究表明,非器质性视力丧失在青春期前儿童中较为常见,大多数病例可通过标准临床测试安全地诊断出来.及时诊断可避免不必要的检查和延长 "病程".同时存在的社会冲突很常见,可能也是诱因之一.向患儿和家长仔细解释并安抚他们的情绪仍然是治疗的主要方法.

权利人:EXXON RESEARCH ENGINEERING CO
摘要:A vanadium, phosphorus oxygen containing catalyst composition capable of partially oxidizing hydrocarbons (e.g., n-butane) to form a carboxylic anhydride (e.g., maleic anhydride), a process for preparing this catalyst, and a process for using this catalyst to form such anhydrides is disclosed. The catalyst composition is prepared by an organic heterogenous technique followed by a water treatment step and activation.

发明人:Schäfer Bernd; SIEGEL WOLFGANG
权利人:BASF SE
摘要:The invention relates to a method for the non-stereoselective and also for the stereoselective synthesis of astaxanthin from astacin. For this purpose, a reducing agent is used selected from the group of hydrogen, a secondary alcohol, formic acid and also the salts of formic acid or from a mixture of at least two representatives of the compound classes stated above. The invention further relates to the use of astacin as starting compound for the synthesis of astaxanthin.
