Polyester round slings are widely utilized in various work environments due to their lightweight, flexible nature and smooth surface that minimizes the risk of cargo abrasion or damage. However, specific guidelines intended to protect round slings from the damage caused by the sharp edges of cargo, thus preventing accidents in case the cargo falls, are lacking in South Korea. In this study, a comparative analysis was conducted on the regulations and guidelines related to round slings in South Korea and the United States. Further, experiments were carried out to determine the relationship between round slings and lifting accessories. The research identified specific shortcomings in the user manuals provided by round-sling manufacturers. Accordingly, certain measures were proposed for enhancing the operational safety of round slings: 1) establish criteria for edge protection of polyester round slings and 2) recommend standardization of the information provided by manufacturers. As developing new standards is a time-consuming task, this study proposes a method for enhancing the operational safety of round slings in the short term by introducing established safety standards from the United States-where safety has been proven over a considerable period of time-into the domestic context. In addition, it is recommended that edge criteria be permanently printed on the labels of round slings.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal lesion with incidental histologic findings. Surgical excision is recommended as the treatment of choice for PASH, although the recurrence rates after excision range from 15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed. Grossly, the specimens were round and well-circumscribed, and the histologic examination revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted, and the nipple areolar complex was transferred to a new position as a free graft. The aesthetic result was satisfactory after twelve months of follow-up.
