This case report describes a young patient who suffered from a recurrence after 5 years. Since all findings, particularly visual evoked potentials, were classic for neuritis, the patient was treated for neuritis although periocular pain was not present. Case Report: Five years after a neuritis of the left eye (OS), the patient was again referred with a visual loss (VA 0.3 OS). In addition to an afferent pupillary defect OS and a constricted visual field OS, an inter- eye latency difference was demonstrated in the visually evoked potentials. The patient was treated with megadose steroid therapy. Although periocular pain as a classic symptom was absent, no neuroradiological imaging was performed. Six weeks later visual acuity and visual fields further worsened, such that a nuclear magnetic resonance imaging was indicated revealing a meningioma frontobasally compressing the optic nerve. After neurosurgical intervention visual acuity and field stabilized. Conclusions: In rare cases, meningioma may mimick the symptoms of neuritis. Therefore, neuroradiological imaging is indicated in recurrences or complicated disease courses, particularly if classic symptoms such as periocular pain are missing.展开更多

This study aims to assess the visual outcomes for patients with parasellar meningioma following FSRT. Methods: A retrospective, non-comparative case series of 13 patients with parasellar meningiomas who were treated in one institution with FSRT between January 1995 and January 2001. Results: 13 patients (26 eyes) were followed for amean of 2 years. Visual acuity improved in four eyes (12.5% ), remained stable in 18 eyes (75% ), and worsened in three eyes (12.5% ). Visual field improved in 15 eyes (57% ), remained stable in six eyes (23% ), and worsened in four eyes (15% ). No adverse visual outcome occurred as a result of radiation. Conclusion: These preliminary findings suggest that FSRT is a safe and effective treatment for parasellar meningiomas.展开更多
文摘用直接快速涂片和缩小视野时钟法,检查粪便细菌分布,并与大便菌群培养定量计数比较,观察分析82例不同年龄组广东健康人群。结果表明:老年组(60 岁～78 岁)和儿童组(3 岁～10 岁)较婴儿组(3 月～12 月)的G- b有明显增加(P< 0.05)。男女性别无显著差异:G+ b 和G- b 的数量,随着年龄的增加而减少;G+ c 则随着年龄增加而增加。通过本次调查我们认为缩小视野时钟法,快速准确简便,容易掌握,价格低廉。
