Article Synopsis
  • The study assessed how well the Haller index can predict the risk of recurrence in patients with primary spontaneous pneumothorax.
  • Data from 285 patients (mostly young men) who had undergone CT scans were analyzed over several years, categorizing them into those who experienced recurrence and those who did not.
  • Results indicated that a higher Haller index was linked to a greater risk of recurrence, suggesting that using this index could help identify high-risk patients for better management strategies.

Introduction: In this study, we investigated the clinical outcomes of patients who underwent surgery with proven lymph node metastasis.

Methods: Patients who were operated for lung cancer with pN1 or pN2 were examined in the study. The clinicopathological features and survival of the subjects were evaluated according to pN1-pN2 status, presence of neoadjuvant treatment, Positron emission tomography and computed tomography (PET/CT) avidity on mediastinal lymph nodes and specific lymph node stations.

Objectives: This study aims to compare the radiological, biomechanical, and histopathological results of microfracture treatment and osteochondral damage repair treatment with a new scaffold product produced by the three-dimensional (3D) bioprinting method containing gelatin-hyaluronic acid-alginate in rabbits with osteochondral damage.

Materials And Methods: A new 3D bioprinted scaffold consisting of gelatin, hyaluronic acid, and alginate designed by us was implanted into the osteochondral defect created in the femoral trochlea of 10 rabbits. By randomization, it was determined which side of 10 rabbits would be repaired with a 3D bioprinted scaffold, and microfracture treatment was applied to the other knees of the rabbits.

Article Synopsis
  • Mediastinal lymphadenopathy with high 18-fluorodeoxyglucose uptake after lung cancer surgery may indicate recurrence, but can also result from foreign body reactions due to previously placed oxidized cellulose.
  • A study evaluated 34 lung cancer patients post-surgery using EBUS-TBNA, classifying outcomes as metastasis, foreign body reaction, or reactive lymph nodes.
  • Results showed that foreign body reactions were relatively common, characterized by an earlier presentation and lower maximum standardized uptake values (SUVMax) compared to metastasis.
