Treatment of open wounds secondary to trauma using polyurethane foams with boric acid particles.

BACKGROUND: To investigate the efficacy of new foams with boric acid particles combined with a negative pressure wound treatment (NPWT) system in open fractures with tissue defects secondary to trauma. METHODS: Forty-nine patients with open fractures secondary to trauma with soft tissue defects who were admitted between 2016 and 2018 were included in the study. Patients were examined in two groups. In Group 1, boric acid-impregnated foams combined with the NPWT system were used in 27 patients, and in Group 2, silver nitrate-impregnated foams combined with NPWT systems were used in 22 patients. In addition to evaluating the broad-spectrum antibacterial feature of silver nitrate, the antimicrobial, angiogenetic, and epithelializing effects of boric acid were investigated macroscopically and histopathologically. RESULTS: A reduction in wound size and granulation was observed in each group. Macroscopically, the reduction in wound size, epithelialization and granulation were pronounced in Group 1 and in Group 2. Microscopically, the number of fibroblasts, collagen synthesis, and angiogenesis were significantly increased in Group 1 compared with Group 2. CONCLUSION: In this clinical trial, both the broad spectrum antimicrobial feature of boric acid and its positive effect on the cells responsible for wound healing were found to be an alternative compared with silver nitrate. The use of new foams with boric acid particles combined with the NPWT system may be a good alternative method in the treatment of open wounds due to trauma.

Stone compositions in Turkey: an analysis according to gender and region.

OBJECTIVE: To evaluate the compositions of the kidney stones obtained from different regions of Turkey and to present the gender and regional differences. METHODS: The study included 6453 kidney stones obtained from patients from different parts of Turkey. All of the stones were obtained using ureterorenoscopy, percutaneous stone surgery, laparoscopic or open stone surgery, or extracorporeal shock wave lithotripsy. X-ray diffraction crystallography method was used for analysis. RESULTS: At the end of the analysis, 11 different stone types including calcium oxalate (Ca-ox) monohydrate (whewellite, COM), Ca-ox dihydrate (weddellite, COD), uric acid, cystine, struvite, biurea, xanthine brushite, quartz, whitlockite, and dahlite were determined either in pure or mixed conditions. Of the stones, 80.4% were Ca-ox (55.7% COM, 5.9% COD, 18.8% COM + COD), 4.8% uric acid, 3.1% cystine, and 3.3% were phosphate stones (dahlite, brushite, struvite, whitlockite). The remaining 8.4% of the stones were in mixed form with different combinations. Of the patients, 4411 were men (68.3%) and 2042 were women (31.7%). CONCLUSION: Ca-ox was the most frequently encountered stone type in our country as it is worldwide. The distribution of the other stone types is different than the other countries. The information about the structure of the stone has significant contribution to the understanding of the stone formation etiology, programming of the treatment process, and prevention of the recurrences. The study is significant in presenting the stone profile of Turkey.
