BACKGROUND Polymethylmethacrylate bone cement cannot provide an adhesive chemical bonding to form a stable cement-bone interface. Bioactive bone cements show bone bonding ability, but their clinical application is limited because bone resorption is observed after implantation. Porous polymethylmethacrylate can be achieved with the addition of carboxymethylcellulose, alginate and gelatin micropa...
Esophageal fibrovascular polyps are rare, benign, submucosal tumors of the upper digestive tract that usually have an indolent course until the lesion attains a very large size. The most frequent complaints associated with these tumors include dysphagia and foreign body sensation. However, a long pedunculated polyp can regurgitate into the pharynx or oral cavity and cause asphyxia and sudden de...
Giant polyps in the esophagus are rarely occurring benign tumors and may contain lipomas, fibrovascular polyps, fibrolipomas or neurofibromas polyps. Clinical symptoms include dysphagia, vomiting, retrosternal pain, shortness of breath, and asthma. In some cases, the polyps are regurgitated into the oral cavity and represent a spectacular manifestation. The reported case in this study was of a ...
Extracranial cerebrospinal fluid (CSF) shunt obstruction is one of the most important problems in hydrocephalus patient management. Despite ongoing research into better shunt design, robust and reliable detection of shunt malfunction remains elusive. The authors present a novel method of correlating degree of tissue ingrowth into ventricular CSF drainage catheters with internal electrical imped...
