Study Design: Resection of a primary malignant tumor of the bone with wide surgical margins has become the golden standard in oncological surgery. In the case of a spinal tumor with tumor invasion of the spinal canal, a wide resection could necessitate resection and subsequent replacement of part of the dura.
Summary Of Background Data: Dura replacement is a consequent surgical step in the treatment of primary malignant tumors of the spine.
Methods: We present the case of a 27-year-old male with a tumor of the dorsal elements of D6. After paraplegic symptoms, a laminectomy of D5 to D7 was performed and histologic examination revealed the presence of an osteosarcoma. After neoadjuvant polychemotherapy, a wide resection of the dorsal elements from D4 to D7 combined with a resection of the dorsal part of the dura was planned. Replacement of the dura was performed with Lyodura (B. Braun Melsungen AG, Melsungen, Germany). The spine was stabilized with an ISOLA instrumentation (Depuy International Ltd., Leeds, England). For wound closure, a pedicled latissimus dorsi flap and split skin graft were necessary. In a second step, ventral spondylodesis with Texas Scottish Rite Hospital instrumentation (Sofamor Danek, Memphis, TN) was performed.
Results: One hundred sixteen months after surgery the patient is alive without evidence of disease, is pain free, and has returned to his profession and life without any restrictions.

Background: Dysbiosis of the lung microbiome can contribute to the initiation and progression of lung cancer. Synchronous multiple primary lung cancer (sMPLC) is an increasingly recognized subtype of lung cancer characterized by high morbidity, difficulties in early detection, poor prognosis, and substantial clinical challenges. However, the relationship between sMPLC pathogenesis and changes in the lung microbiome remains unclear.

While bone, liver, and lung metastases are well-documented, central nervous system (CNS) involvement, particularly spinal and meningeal metastases, is extremely rare. We present a 41-year-old male with nasal obstruction and diplopia, diagnosed with locally advanced NPC.

Although osteosarcomas are the most frequent primary malignant bone tumors, the primary cranial manifestation of this condition is very rare with only a limited number of cases presented in the literature. We present the case of a 20-year-old male patient who underwent single-session surgical intervention for resection of right frontal osteosarcoma with a tailor-made craniotomy and cranioplasty using virtually designed 3D-printed templates and molds. Subsequently, the patient was treated according to the EURAMOS protocol and received adjuvant systemic chemotherapy.

Objective: This study aims to analyze the adverse drug events (ADEs) associated with tolvaptan in the Food and Drug Administration Adverse Event Reporting System database from the fourth quarter of 2009 to the second quarter of 2024.
Methods: After standardizing the data, various signal detection techniques, including Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network, and Multi-Item Gamma Poisson Shrinker, were employed for analysis.
Results: Among the 7,486 ADE reports where tolvaptan was the primary suspected drug, a total of 196 preferred terms were identified, spanning 24 different system organ classes.
Enhancing diagnostic accuracy in breast cancer: integrating novel machine learning approaches with enhanced image preprocessing for improved mammography analysis.

Purpose: This study explored the use of computer-aided diagnosis (CAD) systems to enhance mammography image quality and identify potentially suspicious areas, because mammography is the primary method for breast cancer screening. The primary aim was to find the best combination of preprocessing algorithms to enable more precise classification and interpretation of mammography images because the selected preprocessing algorithms significantly impact the effectiveness of later classification and segmentation processes.
Material And Methods: The study utilised the mini-MIAS database of mammography images and examined the impact of applying various preprocessing method combinations to differentiate between malignant and benign breast lesions.
