Intradiploic meningioma of the orbital roof is a type of intraosseous meningioma. It is very rare in children, and only 7 cases have been reported in the pediatric age group. We report a case of a 14-year-old female who presented with progressive exophthalmos, diplopia and pain involving the right eye. Computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed an intradiploic orbital roof tumor with diploe expansion and pneumosinus dilatans. The tumor was completely removed surgically. The histopathological diagnosis was transitional meningioma. The clinical and radiological findings of intadiploic meningioma are discussed with a review of the relevant literature. 相似文献

Narrow-band ultraviolet B treatment for vitiligo,pruritus, and inflammatory dermatoses 总被引:8,自引:0,他引:8

BACKGROUND: Narrow-band ultraviolet B (NB-UVB) therapy has been used successfully for the treatment of inflammatory and pigmentary skin disorders including atopic dermatitis, psoriasis, mycosis fungoides, polymorphous light eruption, and vitiligo. METHODS: This is a retrospective review of the treatment outcomes of 117 consecutive patients with vitiligo, pruritus, and other inflammatory dermatoses, excluding those with psoriasis and CTCL, who were treated with NB-UVB between 1998 and 2001 at our institution. RESULTS: Approximately 80% of all patients showed improvement in their condition. NB-UVB phototherapy was well tolerated, with no serious adverse effects. In patients with vitiligo, 6.4% had an abnormal thyroid-stimulating hormone level and 6.5% had anemia. CONCLUSION: NB-UVB may be considered as a viable therapeutic option in the treatment of vitiligo, pruritus, and other inflammatory dermatoses. Long-term adverse effects and cost-benefit analysis of NB-UVB therapy compared to other treatment modalities remain to be determined. 相似文献

In this study, the potential antidepressant-like effects of pioglitazone and the possible involvement of peroxisome proliferator-activated receptor gamma (PPARγ) and nitric oxide system in antidepressant effects of pioglitazone were determined using forced swimming test (FST) in mice.
Method
After assessment of locomotor activity in open-field test, mice were forced to swim individually and the immobility time of the last 4 min was evaluated. Pioglitazone was administered orally with doses (5, 10, 20 and 30 mg/kg) 2 and 4 h before FST. To assess the involvement of PPARγ in the possible antidepressant effect of pioglitazone, GW9662, a PPARγ antagonist (2 mg/kg) was administered before pioglitazone (20 mg/kg). For determination of possible role of nitric oxide pathway in this effect, a non-specific NOS inhibitor, Nω-nitro-l-arginine methyl ester (l-NAME, 10 mg/kg, i.p.), a specific iNOS inhibitor, aminoguanidine (50 mg/kg, i.p.), or a NO precursor, l-arginine (750 mg/kg, i.p.) was co-administered with pioglitazone, either 2 or 4 h before FST.Results
The immobility time significantly decreased after pioglitazone administration (20 and 30 mg/kg). GW-9662 significantly reversed antidepressant effect of pioglitazone administered 2 and 4 h prior to FST. Co-administration of non-effective doses of pioglitazone and l-NAME revealed antidepressant-like effect in FST; while, co-administration of non-effective doses of aminoguanidine and pioglitazone did not affect the immobility time. l-Arginine also reversed the antidepressant-like effect of pioglitazone.Conclusion
The antidepressant-like effect of pioglitazone on mice in the FST is mediated at least in part through PPARγ receptors and nitric oxide pathway. 相似文献86.

Intracranial arteriovenous malformations (AVMs) are congenital lesions frequently diagnosed as a result of hemorrhage or other neurological symptoms. Prevention of such devastating neurological injury has promoted a variety of treatment strategies. The rich history of multimodal therapy in the treatment of AVMs includes microsurgery, endovascular embolization, and stereotactic radiosurgery (SRS). This article reviews the biology and natural history of AVMs, as well as their treatment with both SRS and endovascular neurosurgery. It considers various paradigms and goals of endovascular treatment, along with relevant issues such as the features of an AVM to be targeted. Issues of the interplay between SRS and endovascular neurosurgery include the compartments of an embolized AVM to contain within the radiosurgery plan, the radioprotective and radiosensitizing effects of the embolic agent, the durability of embolization, and the sequencing of embolization with respect to the radiosurgical treatment. Published literature on these topics is sparse, and the flimsiness of the data offers limited guidance. 相似文献

目的:探讨隔日应用0.005%拉坦前列素对青光眼患者眼压(intraocular pressure,IOP)的效果。方法:该研究中的开角型青光眼患者控制较好,在研究的第一阶段睡前给予拉坦前列素,每日一次,至少2mo。3次连续IOP正常后,改为隔日一次睡前用药,并且在研究第二阶段的1,2,4,6,8和12wk密切监测患者,进行IOP测量。遇到一次IOP异常升高,则患者被排除研究并且前期方案将重建。结果:这项研究包括53例53眼开角型青光眼(男29例,女24例,年龄52~82岁)。27例患有原发性开角型青光眼,26例患有假性剥脱性青光眼。研究的第二阶段开始后,IOP有温和增长趋势,并分别在女性和男性患者中检测到。第1,2,4,6,8和12wk的P值分别为0.003,0.001,0.000,0.000,0.000和0.000。在第二阶段开始后的前2wk,66%的病例没有IOP改变,但此后,69.8%患者眼压增加。结论:该研究显示常规用量0.005%拉坦前列素与隔日一次剂量相比,具有优越性,但至少在最初的几个星期,IOPs比较接近对方。进一步的多患者研究将扩大目前的研究结果。 相似文献
