Exploring versatile applications of a vacuum-assisted bone harvester in orthopedic surgery.

Background: Orthopedic procedures often require removing bone or pathological tissue, with traditional methods involving instruments like curettes and rongeurs. However, these methods can be time-consuming and lead to increased blood loss. To mitigate these side effects, vacuum-assisted tools have been developed to aid in tissue removal.

An optimized method for IgE-mediated degranulation of human lung mast cells.

Background: Mast cells are critically involved in IgE-mediated diseases, e.g., allergies and asthma.

Uniportal video-assisted thoracic surgery: segmentectomy versus lobectomy-early outcomes.

Objectives: To assess the feasibility and safety of uniportal video-assisted thoracoscopic pulmonary segmentectomy compared with lobectomy by studying early postoperative outcomes.

Methods: We included all patients who underwent uniportal segmentectomy and lobectomy between 2017 and 2022 at Karolinska University Hospital. Early clinical outcomes were compared between the uniportal segmentectomy and lobectomy groups.

Giant cell tumor of bone in the pediatric population: a retrospective study highlighting cases of metaphyseal only location and increased local recurrence rates in skeletally immature patients.

Objective: To describe the presentation of giant cell tumors (GCT) of the bone in the pediatric population to (1) improve the differential diagnosis of pediatric bone tumors and (2) identify the origin of GCT. Understanding the origin of bone tumors assists in establishing appropriate diagnoses and recommending treatment options. This is particularly important in children, where evaluating the need for invasive procedures is balanced with the desire to avoid overtreatment.

Regional anesthesia is associated with improved metastasis free survival after surgical resection of bone sarcomas.

There is increasing evidence that perioperative factors, including type of anesthesia, may be an important consideration regarding oncological disease progression. Previous studies have suggested that regional anesthesia can improve oncological outcomes by reducing the surgical stress response that occurs during tumor resection surgery and that may promote metastatic progression. The purpose of this study is to provide the first robust investigation of the impact of adding regional anesthesia to general anesthesia on oncological outcomes following sarcoma resection.
