OBJECTIVES AND IMPORTANCE: Cervical spine compromise by fibrous dysplasia is rare; only 20 cases have been reported. Treatment was surgical in six cases, but the management differed among the other cases. In this retrospective case report, we analyze and discuss the surgical treatment of this condition in the context of previous reports. CLINICAL PRESENTATION: A 35 year-old woman presented 1 week after the onset of spontaneous neck and left arm pain, which increased 48 hours later. A physical examination revealed only slight neck stiffness. Her previous history was unremarkable. Plain radiographic, radioisotope bone scanning, and computed tomographic studies were performed. The body of the fifth cervical vertebra was collapsed. INTERVENTION: A C5 corpectomy was performed, and the spine was reconstructed with a block of biocompatible osteoconductive polymer and a plate with four bicortical screws. Pathologic examination revealed fibrous dysplasia. The postoperative course was uneventful, and the pain disappeared. Radiographs obtained postoperatively demonstrated good spinal alignment. The patient was discharged after 7 days. Three years later, she continued to have no pain, and spine stability was preserved. CONCLUSION: Good results can be achieved in the surgical treatment of dysplastic tissue with the use of instruments for spine reconstruction and synthetic grafting to prevent invasion.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.
Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.
Review of Outcomes After Peripheral Nerve Transfers for Motor Nerve Injury in the Upper Extremity.

Division of Plastic and Reconstructive Surgery, University of Colorado School of Medicine, Anschutz Medical Center, Aurora, Colorado.
Background: Modern nerve-to-nerve transfers are a significant advancement in peripheral nerve surgery. Nerve transfers involve transferring donor nerves or branches to recipient nerves close to the motor end unit, leading to earlier reinnervation and preservation of the musculotendinous units in proximal nerve injuries. After nerve reinnervation, function may be superior to traditional tendon transfer techniques in terms of strength and independent motion.

Department of Gastroenterology, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang, China.
Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.
Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.
Exploring Denosumab in the Treatment of Giant Cell Tumors: Clinical Evidence and Controversies.

Giant cell tumors (GCTs) are benign but locally aggressive bone neoplasms that primarily affect skeletally mature individuals. They are characterized by a tendency for recurrence and being associated with significant morbidity. Traditional treatment has focused on surgical resection; however, the role of medical therapies, such as Denosumab, a bone anti-resorptive drug, which has been Food and Drug Administration (FDA)-approved for unresectable GCTs since 2013, recently has gained prominence.

Background: Refractory ascites (RA) remains a serious complication in patients with cirrhosis. Currently, the insertion of a TIPS is considered the standard of care in these patients. To achieve symptom control in those with TIPS contraindications, tunneled peritoneal catheters (PeCa) or ascites pumps were introduced.
