Tracheoesophageal fistula following blunt trauma to the right chest

Tracheoesophageal fistula after blunt trauma is very rare. Typically the patient is a young male driving a car and is thrust onto the steering wheel following sudden deceleration as in a high speed road traffic accident. In our case that victim is a motorcyclist who fell down on his right side and developed such a fistula after 3 days. We report the clinical summary and a brief review of literature.     

Optimal Number of Fixation Pins for Dedicated Mini Jig Cutting Guides During Navigated Total Knee Arthroplasty

Purpose: The optimal number of fixation pins for minimally invasive cutting guides in computer-navigated arthroplasty has not been determined. The authors hypothesized that more fixation pins will lead to greater mechanical stability and more accurate resections. Materials and Method: 12 bovine knee joints were divided into three groups with differing numbers of fixation pins. The ASM [Stryker] knee navigation system was utilized to perform resections, and accuracy of alignment and posterior slope was measured. Comparison was performed between the groups to calculate average differences between predicted and actual resection with differing number of pins. Results: The difference between actual and predicted values showed a trend toward diminishing with a greater number of fixation pins. The mean difference in coronal alignment of predicted versus actual resection was 0.75° for two fixation pins, 0.5° for three pins and 1° for four fixation pins. Similarly, the difference between posterior slope was 2.75°, 2°, and 1°, respectively. Conclusion: This study reveals a trend toward greater accuracy of resections with more fixation pins. Further investigation may be beneficial.     

Internet of things for knowledge administrations by wearable gadgets

The novel gadgets are associated constantly at a quick phase for the development of Internet of Things (IoT). Wearable gadgets are another gathering development in those available gadgets. The recent method in gadgets is to coordinate with IoT and idea is implementing the remote sensor systems that convey novel encounters in day by day exercises. Here, I exhibit a regular day to day existence application including a Wireless Sensor Networks (WSN) for gaming situation. By using this, the physical factors of sports person are estimated and directed by wearable gadgets to Wireless Sensor Networks. The end goal to incorporate diverse equipment stages and to present an administration situated semantic middleware arrangement hooked on a solitary request also utilization of Enterprise Service Bus (ESB) is introduced as a scaffold to ensure coordination of the distinctive conditions and interoperability. Through proposed method everyone can procure information by introducing framework to fresh client. Those clients would be able to get to the information through a wide assortment of gadgets (cell phones, tablets, and PCs) and working frameworks (Android, Windows, Linux, iOS, and so on). Finally we introduced one case study of football match for monitoring 11 players and acquiring data’s and to predict the real time situation in football ground.     

Different transcatheter strategies for aortic coarctation associated with patent ductus arteriosus

BackgroundOlder patients with combination of aortic coarctation and large patent ductus arteriosus can be managed with transcatheter interventions. The strategies depend on anatomy of coarctation and size of ductus arteriosus.MethodsWe present three different patients with this combination. The anatomic factors like isthmic hypoplasia, dilatation of post coarctation descending aorta and size of ductus arteriosus were noted.ResultsPatients with isthmic hypoplasia needed stent angioplasty of the coarctation. If there is no dilatation of post coarctation aorta, a single covered stent excluded the ductus arteriosus and relieved the coarctation gradients. Dilated post coarctation aorta precluded a covered stent and warranted closure of duct with occluder device and stent angioplasty of coarctation. When there is a good sized aortic isthmus in a discrete membranous coarctation, device closure of the duct and balloon aortoplasty was successful.ConclusionsIn coarctation with patent ductus arteriosus associated with good sized aortic isthmus, closure of duct with duct occluder device and balloon aortoplasty would correct the lesions. If there is isthmic hypoplasia, device closure of the duct and stenting of the coarctation is needed. Covered stent is a reasonable alternative only in presence of non dilated descending aorta.
