Background: Choroidal neovascularization occurs in a wide spectrum of conditions, including degenerative, inflammatory, traumatic and hereditary conditions, all of which are characterized by breaks in Bruch’ s membrane. A few cases of choroidal neovascular membrane (CNVM) have been reported in the literature following macular hole surgery. Method: We present a retrospective case study of a single patient who developed CNVM after successful macular hole surgery. The 70- year-old diabetic female underwent macular hole surgery in her right eye. Posterior hyaloid was separated with suction and vitrectomy was performed. Internal limiting membrane (ILM) was stained with trypan blue under air and ILM peeling was performed. Perfluoropropane (C3F8) gas was used as the tamponade. Six weeks post-operation, closure of macular hole was seen. Six months later, she presented with defective vision. Subfoveal classic CNVM was seen in the same eye Discussion: About 1% - 3% of patients who undergo macular hole surgery develop CNVM. Age-related changes and surgical trauma are considered to be the predisposing factors in reported cases. Injury to the retinal pigment epithelium (RPE) during surgery may be an important factor in our case, since there were no pre-existing age-related changes. Conclusions: CNVM though rare can occur after macular hole surgery, especially in the setting of age-related changes. Injuries to the RPE should be avoided during surgery. We report a case of CNVM after macular hole in which trypan blue was used as a staining agent.

Objective. - This 1- year, open- label, multicenter study was designed to assess the long- term tolerability and efficacy of sumatriptan nasal spray 20 mg in adolescent patients with migraine. Methods. - A prospective, multicenter, open- label study was conducted in patients aged 12 to 17 years who were allowed to treat an unlimited number of migraines at severe, moderate, or mild pain intensity with sumatriptan nasal spray for up to 1 year. All patients started the study at the 20- mg dose of sumatriptan nasal spray. Dose could be adjusted downward to 5 mg at the discretion of the investigator to optimize therapy. Results. - A total of 484 adolescent migraineurs treated 4676 migraines with sumatriptan nasal spray 20 mg (3593 during the first 6 months and 1083 during the second 6 months). A total of 3940 migraines and 699 migraines were treated with one and two 20- mg doses of sumatriptan nasal spray, respectively. Only 10 patients (treating 42 migraines) took the 5- mg dose of sumatriptan nasal spray. The overall percentage of migraines treated with either one 20- mg dose or one, two, or three 20- mg doses with at least 1 drug- related adverse event was 19% . The most common specific drug- related adverse event was unpleasant taste, reported in 17% of migraines. No other single drug- related adverse event was reported in more than 1% of migraines over the 1- year treatment period. When unpleasant taste was excluded from the adverse- event tabulations, the percentages of migraines with at least 1 drug- related adverse event after one or one, two, or three 20- mg doses declined to 4% and 3% , respectively. No patient experienced any drug- related changes in 12- lead ECGs, vital signs, or nasal assessments; and no clinically meaningful changes in clinical laboratory values were observed. Across all migraines with evaluable efficacy data (n = 4334), headache relief was reported in 43% of migraines at 1 hour and in 59% at 2 hours after dosing with sumatriptan nasal spra

Renal replacement therapy(RRT) resources are scarce in India, with wide urban-rural and interstate disparities. The burden of end-stage renal disease is expected to increase further due to increasing prevalence of risk factors like diabetes mellitus. Renal transplantation, the best RRT modality, is increasing in popularity, due to improvements made in public education, the deceased donor transplantation(DDT) programme and the availability of free and affordable transplant services in government hospitals and certain non-governmental philanthropic organizations. There are about 120000 haemodialysis patients and 10000 chronic peritoneal dialysis patients in India, the majority of them waiting for a donor kidney. Shortage of organs, lack of transplant facilities and high cost of transplant in private facilities are major barriers for renal transplantation in India. The DDT rate in India is now 0.34 per million population, among the lowest in the world. Infrastructural development in its infancy and road traffic rules not being strictly implemented by the authorities, have led to road traffic accidents being very common in urban and rural India. Many patients are declared brain dead on arrival and can serve as potential organ donors. The DDT programme in the state of Tamil Nadu has met with considerable success and has brought down the incidence of organ trade. Government hospitals in Tamil Nadu, with a population of 72 million, provide free transplantation facilities for the underprivileged. Public private partnership has played an important role in improving organ procurement rates, with the help of trained transplant coordinators in government hospitals. The DDT programmes in the southern states of India(Tamil Nadu, Kerala, Pondicherry) are advancing rapidly with mutual sharing due to public private partnership providing vital organs to needy patients. Various health insurance programmes rolled out by the governments in the southern states are effective in alleviatin

2015年4月25日尼泊尔中部的廓尔喀发生了M_W7.8地震,随后的5月12日,在距此震震中以东约140km处又发生了M_W7.3地震。这两次地震的发生为我们理解喜马拉雅山的地震提供了新的视角和机遇。本文试图基于这两次事件所产生的形变场以及它们余震的时空特征分析这些地震的地震构造。结合震后对当地的破坏和地表形变等的实地考察可明显看出,尽管主震滑动主要局限于主喜马拉雅逆冲断裂(MHT),但破裂并没有扩展至主前缘逆冲断裂(MFT)。由形变场现有的合成孔径雷达干涉测量图像支持的野外证据表明,滑动分量可能在先前识别出的失序逆冲/活动逆冲区出现,该区域平行于主中央逆冲断裂(MCT),即文献中描述的与地形一致的地理转换带PT_2。第一次破裂终止后触发了第二次大地震,余震的分布在空间上仍局限在PT_2最东端。2015年发震序列的机理表明,失序逆冲断层吸收了部分滑移量,依据当前对地震机理的理解,此次地震始于主喜马拉雅逆冲断裂。
