Malignant Injury Research Articles

Research on the Application of VR/AR Interactive Design Technology in the Field of Public Security

Disease, earthquake, fire, stampede, malignant injury and so on. In all kinds of sudden events, the design of public emergency rescue facilities is more and more important. Public emergency refers to an emergency that occurs suddenly, causes or may cause heavy casualties, property losses, ecological environment damage and serious social harm, and endangers public security, which is characterized by abruptness, severity and wide impact. The occurrence of these incidents will destroy the normal social operation mechanism and the normal social order, cause a huge social psychological crisis, hinder social stability and development.

A Critical Review of Post Endoscopic Sub-Mucosal Dissection (ESD) Delayed Bleeding Risk Factors

Endoscopic sub-mucosal dismemberment (ESD) has become a settled strategy for treatment of shallow neoplasms in the gastrointestinal tract. In three local areas, ESD was introduced to overcome traditional endoscopic mucous resection (EMR) and inadequate resection of the EMR, combining mouth, stomach, and the colon, for early disruptive sores. ESD was grown first in Japan since that nation has the highest predominance of gastric malignant growth on the planet. Endoscopic sub-mucosal analyzation causes enormous fake ulcers with more severe dangers of intra-usable and deferred postoperative draining. However, there is no agreement in regards to the ideal peri-usable administration for the anticipation of free draining and the advancement of ulcer mending. The hugeness of this investigation is to locate a superior procedure to bring down the hazard post ESD draining and to plan to defeat the confinements of regular EMR (endoscopic mucosal resection) and fragmented resection for early malignant injuries in the three districts which incorporate throat, stomach, and colon. However, it has considered a standard in Eastern Asian nations and Japan because of the incredible importance of ESD. The EMR and ESD approaches are discussed in this report. Thus, the warning factors for early gastric neoplasms of PPB after ESD were established, and a superior technique was created to mitigate the danger of ESD dying. EMR was already widely used for treating early neoplastic sores in the gastrointestinal tract; colon adenoma and colorectal tumors are widely acknowledged.

Aneurysmal bone cyst: Case report and literature review

The aneurysmatic bone cysts are uncommon bone injuries, but well-recognized occurring a more frequent in long bones and vertebrae of patients with <30 years. As a distinct entity, it was fi rst described by Lichtenstein, they rarely occur in the maxillary sinuses, which may occur concomitantly with other injuries such as brous dysplasia, and central injury of giant cells. The etiology and pathogenesis of this injury are still not completely elucidated, and there is controversy whether injuries arise anew or represent some form of vascular accident in a preexisting injury. Their clinical characteristics such as fast growth, expansion, cortical destruction and osteoid formation can easily confuse the clinician about malignant injuries. This is a case report of a pediatric patient treated of an aneurysmal bone cyst (ABC) associated with juvenile ossifying broma in Buccal Maxillofacial Surgery of Service of Pedro Ernesto Hospital.

Local radiation injury and its surgical treatment. Report of 170 cases.

170 cases of local radiation injury were treated by excision and immediate covering of the defect by various reconstructive methods. Initial diagnosis was in 32% benign diseases, in 44% skin carcinomas and in 24% deep malignant tumours. Postoperative histological diagnosis was nonulcerated atrophy in 24%, atrophic ulceration in 45%, necrotic ulceration in 9% and radiation-induced malignancy in 22%. The mean interval between radiation and operation was 12 years in cases of non-malignant radiation injury and 24 years in cases of malignant injury. In 81% irradiation had been given to the head and neck area and in only 6% to extremities. Basal cell carcinomas were six times as common as squamous cell carcinomas. As method of reconstruction, direct suture to eight by bone grafting. Cases of malignancy gen-41%, transposition flap in 8%, tube pedicle flap in 14% and bone graft in 2%. The mean number of operations per patient varied from one with reconstruction by direct suture to eight by bone grafting. Cases of...
