Effect of platelet-rich plasma combined with negative pressure wound therapy in treating patients with chronic wounds: A meta-analysis

A meta-analysis was conducted to comprehensively explore the effects of platelet-rich plasma (PRP) combined with negative pressure wound therapy (NPWT) in treating patients with chronic wounds. Computer searches were conducted, from database infection to November 2023, in EMBASE, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure databases for randomized controlled trials (RCTs) on the use of PRP combined with NPWT technology for treating chronic wounds. Two researchers independently screened the literature, extracted data and conducted quality assessments according to the inclusion and exclusion criteria. Stata 17.0 software was employed for data analysis. Overall, 18 RCTs involving 1294 patients with chronic wounds were included. The analysis revealed that, compared with NPWT alone, the use of PRP combined with NPWT technology significantly improved the healing rate (odds ratios [OR] = 1.92, 95% confidence intervals [CIs]: 1.43-2.58, p < 0.001) and total effective rate (OR = 1.31, 95% CI: 1.23-1.39, p < 0.001), and also significantly shortened the healing time of the wound (standardized mean difference = -2.01, 95% CI: -2.58 to -1.45, p < 0.001). This study indicates that the treatment of chronic wounds with PRP combined with NPWT technology can significantly enhance clinical repair effectiveness and accelerate wound healing, with a high healing rate, and is worth further promotion and practice.

Liquid nitrogen for cryotherapy treatment for osteosarcoma of the middle femur: A case report

Background

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. Cryotherapy liquid nitrogen has been used an adjuvant treatment for tumors for some decades.

Case presentation

A 23‐year‐old male patient was admitted to our hospital, mainly due to progressive pain in his left thigh, and confirmed osteosarcoma by local biopsy. A total length of 28 cm tumor bone was completely resected at the region of above and below lesion 3 cm under the guidance of MRI. After removed part of the tumor tissue, tumor bone was dealt with liquid nitrogen for 20 minutes. Finally, the bone was fixed with intramedullary needles for reconstruction. Three months after surgery, the X‐ray examination showed poor bone growth at both distal sides of osteotomy and disuse degeneration of knee joint. The patient was performed an incision on the lateral side of the distal left thigh to secure the locking plate, and followed up every 3 months. Two years after operation, there was no sign of local recurrence.

Conclusion

Liquid nitrogen for cryotherapy may be a feasible local therapy for large lesion of osteosarcoma in middle femur.

Surgical management of spinal liposarcoma: a case series of 7 patients and literature review

PURPOSE

Liposarcoma, one of the most common soft tissue sarcomas originates from primitive mesenchymal cells. But spinal involvement of either primary or metastatic liposarcoma is rare. Here we present our experience of seven consecutive patients with spinal liposarcoma.

METHOD

We retrospectively reviewed our patients who have spinal liposarcoma from January 2009 to December 2013. All patients were surgically treated at least once at our spine tumor center and be confirmed as liposarcoma after surgery. All patients' information and follow-up data were collected afterwards.

RESULTS

A total of six male and one female patients have been included. Five of them had mobile spinal involvement while the others had sacral involvement. Six piecemeal and one en-bloc resections were successfully performed. Patients' Frankel scores were upgraded with one level or at least preserved postoperatively. The average time of follow-up was 24.6 ± 13.9 months. Three patients died 13, 15 and 24 months after surgical treatment, respectively while the other four patients were still alive and one of them alive with disease at the end of follow-up.

CONCLUSION

The outcome and prognosis of spinal liposarcoma is poor, and surgical resections should be considered when diagnosis is confirmed. For those whose tumors were too large to resect and/or with multiple metastases, effective treatment options are currently limited. Therefore, multidisciplinary treatment should be adopted, intraoperative chemotherapy, systemic chemotherapy and radiotherapy for instance.
