Among the most consolidated dogmas in obstetrics, we have the essential role of oxytocin during: labor by regulating, consolidating uterine contractions, by supporting the expulsive efforts of the patient during childbirth and after childbirth by preventing postpartum hemorrhage. But what challenged us to conduct our study is the large and increasing number of surgical operations for postpartum hemorrhage in patients who received oxytocin during labor. We assumed that the generalization use of oxytocin in all patients during labor is probably responsible of this increasing rate of incidents. To verify this assumption, we carried out a prospective randomized comparative study, involving 3990 pregnant patients admitted at the start of labor at term, with no contraindication for giving birth by normal ways, during a period of 10 months (January-October 2022). The patients have been divided into 2 groups. The first group comprises 1991 patients who were placed on admission on a glucose serum infusion with 4 ampoules of a non-anticholinergic musculotropic antispasmodic: “Hydrated phloroglucinol + trimethylphloroglucinol” (Each ampoule contains 40 mg of hydrated phloroglucinol and 0.04 mg of trimethylphloroglucinol) instead of receiving oxytocin during the active phase of their labor and a second group consisting of 1999 patients who received oxytocin during the active phase of their labor. The results were very surprising and contrary to the already consolidated evidence in our specialty. Indeed, the rate of postpartum hemorrhages was 10 patients (0.5%) in the 1st group vs 30 patients (1.5%) in the 2nd group, 9 patients (0.4%) presented fetal heart rate abnormalities in the 1st group vs 90 (4.5%) in the 2nd group, 8 cases (0.4%) of dynamic dystocia in the 1st group vs 132 cases (6.6%) in the 2nd group and 99 caesareans (5%) in the 1st group vs 299 (15%) in the 2nd group. Against all expectations the results were very surprising, with more details in the article.

Open Journal of Medical Imaging 2014年第2期4卷 95-101页

作者： Taha Kamel Alloush Mahmoud Haroun Ibrahim Nahed Salah El Dein Ahmed Ibrahim Ghada samir El-Shahed Lobna Mohamed Nabil El-Sayed Mohamed Hamdy Ibrahim Hosam Ahmed Azmy Faculty of Medicine Ain Shams University Cairo Egypt Ministry of Health Cairo Egypt

Objectives: To assess the impact of atrial fibrillation on stroke severity and short-term (1 month) mortality. Materials and Methods: Totally 200 patients admitted to Ain Shams University Specialized Hospital were recruited and diagnosed clinically to have acute ischemic stroke within 3 days. Patients with hemorrhagic infarctions were excluded. History taking about previous heart disease was taken, full general and neurological examinations were done. Full metabolic profile, full cardiac investigations, carotid duplex, MRI brain stroke protocol with initial clinical evaluation and after 1 month re-evaluation using (NIHSS ) scale. Results: All patients underwent transthoracic echocardiography which revealed absence of “A” wave corresponding to atrial fibrillation in 33 patients (16.5%). Those Patients with atrial fibrillation had a median NIHSS score of 11.00 with IQR of 6.00 - 18.50 at admission and 6.00 with IQR of 2.00 - 14.50 after one month. Patients with atrial fibrillation showed significantly higher NIHSS at admission than patients in sinus rhythm, P < 0.05. Magnetic resonance imaging findings showed that MRA showed significant intracranial vessel stenosis in 117 (79.1%) patients. 51 (34.4%) patients had lacunar infarction, 65 (43.9%) patients had partial anterior circulation infarction, 25 (16.2%) patients had posterior circulation infarction and 7 (4.7%) patients had total anterior circulation infarction. 111 (75%) patients showed leucoaraiosis. Conclusion: Atrial fibrillation was found not to have significantly statistical effect on stroke severity and short term mortality.

This article presents research and development of an interoperable platform to facilitate, monitor and coordinate groundwater data sharing. This system was orchestrated by a number of services described by Open Geospatial Consortium (OGC) such as Sensor Observation Service (SOS) and other services for the use of mapping data, Web Feature Services (WFS), Web Map Service (WMS), and catalogue services (CSW). An important activity for our project was the establishment of a portal for geographic data and services. Geoportal developed for this project will promote and facilitate access to groundwater data and share theme more openly. Otherwise our system has been designed to provide a powerful tool that enhances the ability of regional staff to monitor near real-time groundwater data (i.e.?piezometric level) and as a result will help provide a more effective response to environmental upsets.

目的制作一款价格低廉、实用的经直肠前列腺穿刺模型。方法对于经直肠前列腺穿刺的初学者,使用模型进行穿刺练习是非常必要的。穿刺练习可以帮助初学者熟悉穿刺的步骤,同时也可提高其操作手法。但目前,可以买到的超声用人体模型均比较昂贵,可使用穿刺练习的模型价格更高,反复使用后容易损坏,且可用于模拟经直肠前列腺穿刺练习的模型少之又少。为此,我们制作了一款可用于模拟经直肠前列腺穿刺练习的模型。制作该模型原料为明胶、琼脂、石墨粉、丙醇和水,模具是丙烯酸材质。模具为圆柱形,分为顶部、底部和中空的体部,顶部和底部为圆盘形,可与体部组合在一起,顶部中心固定一直径约3cm的圆柱体,底部在周边固定有8个细针以放置穿刺用目标物。在烧杯中将明胶、琼脂和水按比例混合,并放在100℃～110℃的油浴中加热,待混合液中没有气泡产生后,将丙醇和石墨粉加入其中,混合均匀后倒入模具内,将顶部盖好放置水平处冷却固定。12小时后移除顶部,模形制作完毕。结果该模型呈圆柱体,黑色,不透明,其中心有一个直径3cm的小洞用于容纳腔内探头、穿刺引导架及穿刺针。通过该装置我们可以使用腔内超声探头观察其内的目标物,并可行穿刺练习。结论该模型在二维超声下其回声均匀细腻,显像良好。由于其造价低廉,图像细腻,设计精巧,非常适合用于经直肠前列腺穿刺练习。

Influence of hospital volume and outcomes of adult structural heart procedures

World Journal of Cardiology 2016年第4期8卷 302-309页

作者： Sidakpal S Panaich Nilay Patel Shilpkumar Arora Nileshkumar J Patel samir V Patel Chirag Savani Vikas Singh Rajesh Sonani Abhishek Deshmukh Michael Cleman Abeel Mangi John K Forrest Apurva O Badheka Interventional Cardiology Borgess Medical Center Internal Medicine Saint Peter’s University Hospital Internal Medicine Mount Sinai St.Luke’s Roosevelt Hospital Department of Cardiology University of Miami Miller School of Medicine Internal Medicine Western Reserve Health Education Internal Medicine New York Medical College Public Health Department Emory University School of Medicine Department of Cardiology Mayo Clinic Department of Cardiology Yale School of Medicine Department of Cardiology the Everett Clinic

Hospital volume is regarded amongst many in the medical community as an important quality metric. This is especially true in more complicated and less commonly performed procedures such as structural heart disease interventions. Seminal work on hospital volume relationships was done by Luft et al more than 4 decades ago, when they demonstrated that hospitals performing > 200 surgical procedures a year had 25%-41% lower mortality than those performing fewer procedures. Numerous volume-outcome studies have since been done for varied surgical procedures. An old adage "practice makes perfect" indicating superior operator and institutional experience at higher volume hospitals is believed to primarily contribute to the volume outcome relationship. Compelling evidence from a slew of recent publications has also highlighted the role of hospital volume in predicting superior post-procedural outcomes following structural heart disease interventions. These included transcatheter aortic valve repair, transcatheter mitral valve repair, septal ablation and septal myectomy for hypertrophic obstructive cardiomyopathy, left atrial appendage closure and atrial septal defect/patent foramen ovale closure. This is especially important since these structural heart interventions are relatively complex with evolving technology and a steep learning curve. The benefit was demonstrated both in lower mortality and complications as well as better economics in terms of lower length of stay and hospitalization costs seen at high volume centers. We present an overview of the available literature that underscores the importance of hospital volume in complex structural heart disease interventions.
