Angle closure glaucoma precipitated by labour

Acute angle closure glaucoma generally occurs in older hypermetropic individuals, precipitated by pupillary dilation. However it is often forgotten that it can occur in younger people and that it does not occur solely as a result of the use of mydriatics or normal pupillary dilation in response to darkness. It is recognised that it can occur during or shortly after a surgical procedure done under either spinal or general anaesthetic. We describe a case of acute angle closure occurring in a 37-year-old woman, precipitated by labour. To our knowledge no such case has been described in the literature.     

颈内动脉接近完全闭塞时的处理

目的由于卒中风险随着狭窄严重程度的增加而升高，因此认为颈内动脉（ICA）接近闭塞患者的卒中风险很高。在现有的随机试验中，还没有专门针对这种情况进行探讨，因此其处理尚存在争汶。方法：对相关文献进行系统评价。结果：对ICA接近闭塞患者的处理还存在争议：一些学者支持进行干预，而另一些学者则认为存在风险或没有益处而反对进行干预。在ICA接近闭塞的有症状患者中进行一项比较外科治疗与最佳内科治疗的多中心前瞻性随机试验似乎非常困难，因为这类研究需要大量的患者。尽管如此，基于目前的证据，似乎很难拒绝手术治疗。结论：由于目前对ICA接近闭塞患者的最佳处理方案仍存在着争议，因此需要前瞻性观察性研究以证实其在有症状和无症状人群中的患病率以及相关的卒中风险。基于目前的证据，大多数医疗中心选择手术治疗，但它相对干内科治疗的特粱尚右待证章．     

Rectal diazepam in the treatment of absence status: a pharmacodynamic study

Rectal administration of diazepam is highly effective in terminating absence status as judged by reduction of spike-wave activity in the EEG. Pharmacokinetic studies indicate that diazepam can have antiepileptic properties at serum levels well below those previously reported as being necessary to achieve a therapeutic effect.
