Background: Surgical site infection is an important complication in the postoperative period among liver transplant recipients. However, little is known about the risk factors in this patient group. Therefore, the objective of this study was to analyze the incidence and risk factors for surgical site infections among adult liver transplant recipients.
Methods: Medical records of adult liver transplant recipients from January 1, 2009, to December 31, 2015, were analyzed in this retrospective cohort study.
Results: We enrolled 156 recipients' medical records. Forty-two (26.9%) cases of surgical site infections were identified. The main isolated microorganisms were methicillin-resistant Staphylococcus species, extended spectrum β-lactamase-producing Klebsiella species, carbapenem-resistant Pseudomonas aeruginosa, carbapenem-resistant Acinetobacter baumannii, and vancomycin-susceptible Enterococcus faecalis. We found that long operative times (≥487 minutes) and differences in body mass index between donor and recipient (≥1.3 kg/m) increased the risk for surgical site infections by approximately 5 times (odds ratio [OR], 5.5; 95% confidence interval [CI], 2.5-11.8), and capillary glycemia ≥175 mg/dL in the first 96 postoperative hours increased the risk by approximately 3 times (OR, 2.97; 95% CI, 1.43-6.17).
Conclusions: There was a high incidence of surgical site infections among the studied population and that some risk factors identified differ from those reported in the scientific literature.

Purpose Of The Study: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity.
Material And Methods: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months.

Introduction: Coarctation of the aorta (CoA) patients often experience recoarctation, the reoccurrence of aortic narrowing, presenting a considerable clinical challenge.
Aim: This study aims to investigate the triggers or contributing factors associated with the development of recoarctation (reCoA) following the initial repair of CoA.
Material And Methods: The retrospective cohort study includes information about 120 patients, who underwent 4 different types of surgical repairs of coarctation of the aorta through left thoracotomy in the period 2012-2022.

A 6-year-old Labrador retriever dog with a history of pneumonia was presented because of an acute onset of dull mentation and coughing. Diagnostic imaging and cytology revealed a pneumothorax, pneumomediastinum, and pleural effusion, consistent with pyothorax. The dog underwent exploratory sternotomy for lung lobectomy of the right cranial and middle lung lobes.

Background And Objective: Thymic epithelial tumors, including thymomas and thymic carcinomas, represent the most common mediastinal tumors and account for up to 50% of all anterior mediastinal tumors. For early stages of these thymic tumors, complete resection of the entire thymus is the recommended treatment. The transition from open surgery to video-assisted thoracoscopic surgery (VATS) and recently to robotic-assisted thoracic surgery (RATS) has fundamentally altered the treatment of thymic tumors.

Thymic epithelial tumors (TETs) are rare neoplasms that include thymomas, thymic carcinomas (TCs), and thymic neuroendocrine neoplasms (TNENs). These three tumor categories differ in aggressiveness, the incidence of recurrence after resection, the pattern of recurrence, and survival outcomes. Owing to the tumor's rarity, randomized trials have not been performed in the initial treatment setting.
