In this paper, the highest level of inter- and intra-observer conformity achievable with different treatment planning systems (TPSs), contouring tools, shapes, and sites have been established for metrics including the Dice similarity coefficient (DICE) and Hausdorff Distance. High conformity values, e.g. DICE(Breast_Shape)=0.99±0.01, were achieved. Decreasing image resolution decreased contouring conformity.

Fibro-osseous lesions of the sinonasal tract: a contemporary review.

Curr Opin Otolaryngol Head Neck Surg

October 2024

Department of Otolaryngology - Head & Neck Surgery, University of Florida, Gainesville, Florida, USA.

Purpose Of Review: Fibro-osseous lesions (FOL) are benign, slow-growing lesions that are often incidentally discovered in the sinonasal cavity. They may necessitate surgical resection in patients with postobstructive sinusitis, or in cases of cranial nerve and orbital compression. We examine the recent advancements in otolaryngology relating to diagnostic characteristics and treatments for FOL, with emphasis on new technologies to improve outcomes and reduce recurrence.

Construction of reusable fluorescent assembled 3D-printed hydrogen-based models to simulate minimally invasive resection of complex liver cancer.

PLoS One

Complex liver cancer is often difficult to expose or dissect, and the surgery is often challenging. 3D-printed models may realistically present 3D anatomical structure, which has certain value in planning and training of liver surgery. However, the existing 3D-printed models are all monolithic models, which are difficult to reuse and limited in clinical application.

Background: Street women are women, who make their living on the streets by begging, sleeping in the streets, or on the sides of roads. They are the most marginalized and neglected segment of society, with little access to health care, including modern contraception, and a lack of knowledge about health services, particularly in Ethiopia. Therefore, this study aimed to examine modern contraceptive utilization and associated factors among street women.

Importance: Radiotherapy (RT) plan quality is an established predictive factor associated with cancer recurrence and survival outcomes. The addition of radiologists to the peer review (PR) process may increase RT plan quality.

Objective: To determine the rate of changes to the RT plan with and without radiology involvement in PR of radiation targets.

Background: Autologous breast reconstruction provides substantial benefits in terms of aesthetics and longevity. However, the risk of flap necrosis poses potential challenges to patients' appearance and psychological well-being, while also escalating health care costs. Consequently, examining the risk factors, assessment techniques, and therapeutic approaches for flap necrosis is critically important.
