Clinical outcomes of hydrofiber foam dressing in the treatment of abrasion wounds: A retrospective study.

Mopeds are a popular mode of transportation in Taiwan, yet collision accidents often lead to abrasion requiring medical attention. While hydrofiber foam dressing (HFD) have proven to help control exudates, reduce the frequency of dressing changes, and preserve more viable tissue, there is currently no established clinical guideline for the treatment of abrasion wounds with dressings. Therefore, the aim of this study was to investigate the clinical outcomes of abrasions treated with hydrofiber foam dressings.

Simplified Fabrication of a Lingual Splint for Management of Mandibular Fractures.

Lingual splints have been used to treat mandibular fractures, particularly in cases of complicated mandibular fractures, and serve as a noninvasive adjunctive procedure for reduction and fixation. Furthermore, when used in conjunction with open reduction and internal fixation, the lingual splint provides feasible external fixation against displacing forces exerted by the robust musculature of the mandible. However, the conventional method for lingual splint fabrication is performed preoperatively, and the procedure is time-consuming.

Relationship between the Number of Repeats in the Neck Regions of L-SIGN and Augmented Virus Replication and Immune Responses in Dengue Hemorrhagic Fever.

C-type lectins play a crucial role as pathogen-recognition receptors for the dengue virus, which is responsible for causing both dengue fever (DF) and dengue hemorrhagic fever (DHF). DHF is a serious illness caused by the dengue virus, which exists in four different serotypes: DEN-1, DEN-2, DEN-3, and DEN-4. We conducted a genetic association study, during a significant DEN-2 outbreak in southern Taiwan, to explore how variations in the neck-region length of L-SIGN (also known as CD209L, CD299, or CLEC4M) impact the severity of dengue infection.
