Culdoscopy in gynecologic diagnosis: A review of 404 cases of endoscopic examination

The results of 404 consecutive cases of culdoscopic examination are presented.The value of this diagnostic procedure is paramount in cases of sterility and some endocrine disturbances.Investigation of lower abdominal pain of unknown origin by means of this examination revealed several examples of retrograde tubal menstruation. This occurrence is not as rare as was previously believed.Culdoscopy is safe with minimal complications when sufficient experience has been gained.The examination speeds up diagnosis and shortens hospitalization.Culdoscopy reduces diagnostic errors to a minimum.In some instances, visualization of the pelvic organs prevents unnecessary exploratory laparotomies and gives positive indications for surgical treatment.No tubal plastic operation should be undertaken before a culdoscopy has been performed.     

Vagal nerve stimulation for refractory epilepsy: the surgical procedure and complications in 100 implantations by a single medical center

In 1997, the US Food and Drug Administration approved the use of intermittent stimulation of the left vagal nerve as adjunctive therapy for seizure control. Vagal nerve stimulation (VNS) has since been considered a safe and effective treatment for medically intractable seizures. The objective of this study is to present our experience with the surgical procedure and outcomes after VNS insertion in the first 100 consecutive patients treated at the Tel-Aviv “Sourasky” Medical Center (TASMC). All patients who underwent VNS device implantation by the authors at TASMC between 2005 and 2011 were studied. The collected data included age at onset of epilepsy, seizure type, duration of epilepsy, age at VNS device implantation, seizure reduction, surgical complications, and adverse effects of VNS over time. Fifty-three males and 47 females, age 21.2 ± 11.1 years, underwent VNS implantation. Indications for surgery were medically refractory epilepsy. The most common seizure type was focal (55 patients, 55 %). Seizure duration until implantation was 14.4 ± 9 years. Mean follow-up time after device insertion was 24.5 ± 22 months. Complications were encountered in 12 patients. The most common complication was local infection (6 patients, 6 %). Six devices were removed—four due to infection and two due to loss of clinical effect. Currently, 63 patients remain in active long-term follow-up; of these, 35 patients have >50 % reduction in frequency of attacks.VNS is a well-tolerated and effective therapeutic alternative in the management of medically refractory epilepsy. The surgical procedure is safe and has a low complication rate.     

Nigella sativa seeds based antibacterial composites: A sustainable technology for water cleansing - A review

The presence of pollutants such as organic dyes and heavy metals in water has become a serious problem for aquatic environment. These pollutants that reach the human body through drinking water pose a serious threat to human life. These pollutants can be responsible for diabetes, cancer, high blood pressure, cardiovascular, neurological arteriosclerosis, and many other serious diseases in the human body. The elimination of such water pollutants is an urgent need of the society. But the present adsorption techniques available are costly and out of reach of the masses. The biofilm formation by bacterial cells onto the solid surface is also a subject of concern. In this regard, many efforts have been made to achieve an effective adsorption technology. Adsorption technology using Nigella Sativa and its composites has gained attention because of the biofilm resistance activities of the Nigella Sativa. Owning to its unique physicochemical characteristics, antibacterial properties of Nigella Sativa based composites provide a preferred material for water treatment. This review puts in a nutshell the application of Nigella Sativa based composites for water treatment. The methods of synthesis and physio-chemical properties Nigella Sativa based materials by making use of various techniques have been discussed in depth. Pollutants removals from water have been discussed in light of various parameters that affect it. The implementing and reusing of the adsorbent are also detailed out. The comparative cost, antibacterial activity, adsorption capacities and partition coefficients have also been discussed. This review will definitely be useful for the scientific community to develop the more sustainable material for water purification with high quality.     

骨形态发生蛋白对去势大鼠股骨颈骨形态、骨密度和骨生物力学的影响

目的:观察在去势大鼠股骨颈植入牛骨形成蛋白后其骨形态、骨密度及骨强度的变化。方法:实验于2006-06/12在解放军兰州军区兰州总医院骨科研究所完成。①实验材料:普通级3个月龄wistar雌性大鼠60只。骨形态发生蛋白冻干粉剂(从幼龄牦牛新鲜长骨皮质中提取)。②实验分组:以同一只大鼠左右肢体为对照,右侧为实验侧,左侧为对照侧。③大鼠摘除卵巢制作绝经后骨质疏松模型经双能X射线骨密度仪检测筛选出造模成功的44只大鼠,实验侧距大转子0.5cm处股骨颈植入牛骨形成蛋白冻干粉剂,对照侧植入牛血清白蛋白。④实验评估:术后4周、8周时麻醉下处死大鼠取材,应用苏木精-伊红染色,组织切片后光镜下观察、CT扫描、双能X射线骨密度仪及万能生物力学机观察大鼠股骨颈骨形态学、骨皮质厚度、骨密度及骨强度的变化。结果:纳入造模成功后的44只大鼠均进入结果分析。①股骨颈骨组织形态学观察:4周时实验侧股骨颈局部骨小梁完整、连续性尚好;对照侧股骨颈局部骨小梁稀少、连续性中断,不完整。8周时实验侧股骨颈骨小梁致密,数量增多、完整,连接成网状结构、分布均匀;对照侧股骨颈骨小梁稀疏、变细、间距变大,呈髓腔扩大。②骨皮质厚度、骨密度及生物力学测定:4周时实验侧和对照侧股骨颈皮质厚度无明显差异,骨密度及最大载荷有明显差异(P<0.05);8周实验侧较对照侧骨皮质厚度明显增加、骨密度、最大载荷均增高[皮质厚度:(2.632±0.042),(1.728±0.034)mm,骨密度:(0.210±0.026),(0.182±0.029)g/mm2,最大载荷:(97.2±8.1),(85.6±7.9)N,P均<0.05]。结论:植入牛骨形成蛋白可以提高去势大鼠股骨颈局部骨皮质厚度、骨密度及生物力学强度,这将可能为绝经后骨质疏松性股骨颈骨折的防治提供一种新的途径。
