Effectiveness of Palatal Mucosa Graft in Surgical Treatment of Sub-Glottic Stenosis

Objectives Mucosal free grafts may be successfully applied in many surgical interventions. This study aims at investigating the feasibility of palatal mucosa graft in sub-glottic field in an animal model. Methods This randomized prospective controlled study was conducted with an animal model. Sub-glottic inflammation was created in 15 adult rabbits in each group and sub-glottic stenosis surgery was applied thereafter. The rabbits in group 1 (control group) underwent segmental resection, partial cricoidectomy, and trachea-thyroid cartilage anastomosis; the rabbits in group 2 underwent segmental resection, cricoplasty, and crico-tracheal anastomosis using free buccal mucosa graft; and the rabbits in group 3 underwent segmental resection, cricoplasty, and crico-tracheal anastomosis using free palatal mucosa graft. Re-stenosis was evaluated after 42 days. Results The percentages of stenosis were 27%±20%, 40%±20%, and 34%±23% for group 1, 2, and 3, respectively and the difference was not statistically significant (P=0.29). Intensive and tight fibrosis was observed in 2 rabbits (13%) in group 1, in 5 rabbits (33%) in group 2, and in 3 rabbits (20%) in group 3. There was not a statistically significant difference between groups (P=0.41). Excessive inflammation was observed in 3 rabbits (20%) in group 1, in 7 rabbits (47%) in group 2, and 3 rabbits (20%) in group 3. There was no a statistically significant difference between groups although inflammation rate was higher in the rabbits which underwent buccal mucosa graft (P=0.18). Conclusion The surgical treatments applied with free mucosa graft reduced anastomosis tension through enabling anastomosis to the distal of cricoid instead of thyroid cartilage. Free palatal mucosa grafts may be used in sub-glottic field, one of the most challenging fields of trachea surgery, due to ease of application and rapid vascularization.

The Efficacy of Platelet-Rich Plasma in the Treatment of Rib Fractures

Background Rib fracture is the most common result of thoracic traumas. Intrapulmonary shunt, alveolar capillary membrane damage, intra-alveolar hemorrhage, and hypoxia may develop following rib fractures. Therefore, prompt treatment is important. The aim of this experimental study was to analyze the effects of platelet-rich plasma (PRP) on rib fractures to secure a speedier and more efficient treatment method. Materials and Methods The study involved 18 New Zealand white rabbits, randomly divided into three groups as Group 1, the sham group with no surgical intervention; Group 2, the control group in which simple rib fractures were applied and no treatment; and Group 3, in which rib fractures were applied and then PRP treatment was administered. Results The mean recovery plate thickness measurements were found to be statistically significantly higher in the PRP group compared with the other groups (p < 0.005). A thicker fibrotic cell proliferation and the formation of many capillaries were observed around the growth plate in the PRP group compared with the other groups. These structures were lesser in the control group compared with the PRP group and at the lowest level in the sham group. Larger and distinct callus formation was observed and a new intramedullary field in the PRP group. Conclusions PRP is a reliable and effective autologous product with minimal side effects, which can be considered as an alternative treatment in patients with rib fractures and used easily in pseudoarthrosis, surgical fracture, or flail chest.

Pulmonary langerhans cell histiocytosis case with diabetes insipidus and tuberculosis

A 19-year-old male patient was observed due to having central diabetes insipidus (DI) for five years. He had a history of smoking 5–10 cigarettes a day for two years, but stopped smoking from the last month. The computerized tomography revealed thin-walled cystic lesions in different sizes more dominantly in the upper lobes and consolidated areas in the left upper and lower lobes. The wedge resection from the right lower lobe revealed pulmonary langerhans cell histiocytosis. Follow-up acid-fast bacteria (AFB) examinations revealed (+++) and antituberculous treatment was started. On the 40th day of the anti-tuberculosis treatment, the patient applied once again due to fever and chest pain. Although infiltrations persisted in the left upper and middle zones in the postero-anterior lung rontgenogram, right-sided pneumothorax was detected. The case is considered tuberculosis and the patient continued to receive anti-TB treatment under the close supervision.

The Right Inferior Pulmonary Vein Related Inflammatory Myofibroblastic Tumor in an Adult Case

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm, which is derived of mesenchymal origin. Here we present an adult case with IMT, the origin of which was considered to be right inferior pulmonary vein. A male patient who was 52 years old, admitted to our outpatient clinic with the complaint of shortness of breath. He had cigarette smoking history for 30 years. On direct posterior - anterior X-Ray of the chest, a well-circumscribed mass with calcification in right hilum of the lung was observed. There was a mass which was extending to the inferior inferior pulmonary vein from right hilum of the lung, was measured 70 × 60 mm on computed tomography of the chest. Hamartoma, teratoma and Castleman Disease were among the possible diagnoses. On diagnostic bronchoscopy, signs of pressure from outside to the bronchi of the right middle and lower lobe was observed. Surgical excision is decided and the mass was totally excised through a muscle-sparing thoracotomy. The mass thought to arise from the inferior pulmonary vein on intraoperative inspection and right inferior lobe excision is undertaken by intrapericardial approach. No postoperative complication is encountered. Histological examination of the mass indicated inflammatory myofibroblastic tumor. Main treatment of IMT is surgical excision with negative surgical margin. Here in we present an IMT which is encountered at an unexpected location is excised completely with right lower lobe excision by an intrapericardial approach.
