Background: Many metastatic brain tumors have a distinct border with normal brain tissue, which facilitates tumor removal. However, residual tumor tissue may be present after surgery when metastatic brain tumors are of cystic type. We have developed a method using hydrofiber dressing to transform cystic-type into solid-type tumors.
Methods: Hydrofiber dressing is a sodium carboxymethylcellulose hydrocolloid polymer with high fluid-absorptive capacity. This material was originally used as a dressing for exudative wounds. Hydrofiber dressing was used for 8 patients with cystic-type metastatic brain tumor. Tumor removal was performed after hydrofiber dressing was inserted into the cyst cavity to transform the tumor into a solid-type tumor.
Results: Transformation of cystic-type metastatic brain tumors into smaller solid-type tumors using hydrofiber dressing facilitated en bloc resection of tumor. The dressing also absorbed residual cyst fluid and was thus also effective in preventing intraoperative dissemination of tumor cells. This approach enabled ideal en bloc resection in all patients. There were no adverse events.
Conclusions: These findings suggest hydrofiber dressing may be useful in surgery for cystic-type metastatic brain tumors.

Unlabelled: is to study the possibility of applying commercial wound coatings for treating infected wounds as a carrier matrix for bacteriophages.
Materials And Methods: Twelve varieties of commercial wound coverings based on biopolymers of natural and synthetic origin, a biological preparation Staphylophag produced by scientific-industrial association Microgen (Russia), registration certificate P N001973/01, and the 3196 test strain (GenBank JARQZO000000000) isolated from a patient with a burn wound have been used in our work. The ability of commercial biological wound coatings to absorb solutions was examined by immersing them in a physiological solution (pH 7.
Comparison of outcome of early tangential excision with autografting versus interactive antimicrobial dressing in deep-partial thickness burn patients: A retrospective analysis.

Article Synopsis
- The study compares early excision and autografting (EG) versus initial non-operative treatment (INO) using modern antimicrobial dressings for deep-partial thickness burns in South Asian patients.
- Results show that EG patients had significantly better wound healing outcomes, with faster healing times and shorter hospital stays compared to INO patients.
- INO patients had a higher rate of complications and a considerable portion required delayed grafting, indicating that EG may be the more effective approach for this type of burn treatment.
A Comparison of Incisional Dressings and Negative-Pressure Wound Therapy for the Prevention of Infection and Wound Complications After Primary Total Hip and Knee Arthroplasty: A Network Meta-Analysis of Randomized Controlled Trials.

Background: Incisional dressings may decrease wound complications and joint infection after total hip and knee arthroplasties (THA; TKA). However, there is no consensus on the superiority of a particular product. This study compared infection and wound complications among randomized controlled trials (RCTs) across various dressing types after primary THA and TKA.
