RESUMO
O objetivo do presente estudo é relatar a construção de um retalho direto de bolsa bipediculada com fixação apendicular à região torácica para o tratamento de lesões extensas no membro torácico direito de um gato. Foi tratado no Hospital Veterinário Unicesumar Maringá - Paraná, um felino de 1 ano de idade, apresentando lesão no membro torácico, após história de briga com outro animal da mesma espécie. Ao exame físico, apresentava fístula e edema no membro torácico direito. O paciente foi anestesiado e foi realizado o desbridamento das áreas desvitalizadas. Como terapia inicial, a lesão foi tratada como ferida aberta, até a formação de tecido de granulação, para posterior correção do defeito empregando retalho bipediculado em bolsa direta, com fixação temporária do membro à parede torácica. Após duas semanas, o membro foi desimplantado e os pontos foram removidos 21 dias após a aplicação do retalho. O uso do retalho permitiu completa cicatrização da ferida, sem ocorrência de hematomas, necrose ou deiscência de sutura. Conclui-se que a utilização do retalho bipedicular é aplicável ao tratamento de feridas traumáticas em membro torácico de felinos.
The aim of the present study is to report the construction of a direct bipedicled pouch flap with appendicular fixation to the thoracic region for the treatment of extensive lesions in the right thoracic limb of a cat. He was treated on Hospital Veterinário Unicesumar Maringá - Paraná, a 1-year-old feline, presenting injury to the thoracic limb after a history of fighting with another animal of the same species. On physical examination, he presented fistula and edema in the right thoracic limb. The patient was anesthetized and debridement of the devitalized areas was performed. As an initial therapy, the lesion was treated as an open wound until granulation tissue was formed for subsequent correction of the defect using a direct pouch bipedicled flap, with temporary fixation of the limb to the chest wall. After two weeks, the limb was unimplanted and the stitches were removed 21 days after flap application. The use of the flap allowed complete wound healing without bruising, necrosis or suture dehiscence. It is concluded that the use of bipedicular flap is applicable to the treatment of traumatic wounds in feline thoracic limb.

Abstract Introduction Laryngotracheal stenosis is a difficult problem with varied etiology and various treatment options. The holmium laser represents another tool for the treatment of benign tracheal stenosis. Objectives To determine the utility of holmium laser treatment for benign tracheal stenosis with regards to safety and efficacy. Methods This was a retrospective case study examining patients with benign tracheal stenosis from 1998-2016 who underwent holmium laser treatment. Determining the safety of this procedure was the primary goal, and complications were monitored as a surrogate of safety. Results A total of 123 patients who underwent holmium laser treatment for benign tracheal stenosis were identified. In total, 123 patients underwent 476 procedures, with follow-up ranging from 1 month to 14 years. No intraoperative or post-operative complications were identified as a direct result of the use of this particular laser. Conclusions The holmium laser is an effective and safe laser to use for tracheal stenosis treatment. It is a contact laser with a short acting distance, which reduces the risk of injury to distal airway structures. Given the favorable experience reported here, the holmium laser should be considered when tracheal surgery is attempted.

Arachnoid granulations are hypertrophied arachnoid villi, which extend from the subarachnoid space into the venous system and aid in the passive filtration and reabsorption of cerebrospinal fluid. These macroscopic structures have been described in various locations, with the transverse and sigmoid sinuses seen as normal variants on imaging. Here we present the occurrence of an enlarged arachnoid granulation at the foramen rotundum where a variant intracranial venous sinus was identified during routine dissection. Variations, such as the one described herein, should be recognised by those who operate or interpret images of the skull base.

Graft stenosis from fibrous granulation tissue is not an uncommon problem in recipients of a transplanted trachea and larynx. We describe the case of a man with a transplanted trachea who was seen for respiratory difficulty and stridor secondary to stenosis. Examination through a rigid bronchoscope and surgical debridement were both performed under anesthesia with sevoflurane alone while the man breathed spontaneously. The outcome of treatment with sequential debridements of fibrotic tissue and autologous stem cell injection was satisfactory and the patient was discharged.

According to previous studies, bacterial infection plays the most important role in the late failures of dental implants. Peri-implantitis has been described as a site-specific infection that causes soft tissue inflammation and bone loss around osseointegrated implants that have performed masticatory functions. To reduce the number of pathogenic species and improve the clinical parameters (that is, probing depth, bleeding on probing, and suppuration) around dental implants, several anti-infective therapies have been developed for peri-implantitis. However, recent reviews have not identified sufficient evidence to support an ideal anti-infective protocol for this disease. This article presents a case of advanced peri-implantitis that was treated with a single surgical anti-infective mechanical therapy. A follow-up visit 12 months post-treatment showed improved clinical features.

Advanced internal resorption affecting the crown of teeth may result in the appearance of a 'pink tooth', which, when located in the root canal, can perforate the external root surface. Therapeutically, this condition represents a clinical challenge and normally requires a combined endodontic and surgical focus. Presented herein are cases of double 'pink tooth' which appeared at different times after orthodontic treatment. In the most severe case, upon radiographic examination and computed tomography, the maxillary right central incisor presented an internal resorption, extending from the pulp chamber to the root middle third. After pulp removal, the debridement of the defect was performed using a 2.5% sodium hypochlorite solution, a #80 Kerr file, and an ultrasonic tip ST-17, aided by a surgical microscope. During the cleaning process, various sites of periodontal communication were identified. Upon controlling the hemorrhaging, the root canal was completely filled with White mineral trioxide aggregate. Within the 3-month follow-up treatment, a pink spot appeared on the maxillary left central incisor, which received conventional root canal therapy. Clinically and radiographically, over 18 months of follow up, both cases responded favorably to the proposed treatments. Therefore, it is important to monitor the patient due to the fact that pulp and periodontal sequelae can develop at varied moments after orthodontic treatment. Furthermore, with the current technology and biomaterials, it is possible to resolve cases with extensive internal perforating resorption through endodontic treatment.

The interference of a blood clot in the first postoperative hours of denta extraxtion wounds was studied in rats. Sixty male albino rats were divided into two groups:Group I, immediately after extraction of maxillary of right maxillary incisor the gingival mucosa was approximated and sutured; Group II, after 6 to 8 minutoes postoperatively the blood clot was removed with saline irrigation and absorbent paper cones. The mucosa was then approximated and sutured. Six animals in each group were sacrificed after 12 hours, 1, 4, 7 and 10 days. There was a profound delay in healing in Group II since, although a new blood clot was later formed, it was not organized. The quality and the constitution, maintenance and retraction of the clot are the regulating factors in connective tissue formation during alveolar healing

The fundamentals of skin grafting are simple and well founded and are becoming more and more useful outside of the fielld of plastic sugery. The two major stumbling blocks at the present time are (l) the problem of getting the recipient area into condition to receive the graft and (2)maintaining the necessary care of the graft after it is placed on the recipient area to be sure of its ultimate survival. The problems of knowing when to use skin graft where to cut them and how to cut them are better understood by the younger surgeons being trained today than they were in the past. Cadaver skin has been a practical, though temporary susbstitute for autogenous grafts in severe burns and debilitated patients other tissues and methods of prolonging their preservation in a viable state are still bening investigated.
