Wound care in calciphylaxis remains poorly defined without evidence-based consensus on timing and technique of surgical intervention. We demonstrate that surgical debridement and subsequent wound closure are safe and effective in calciphylaxis and describe a systematic multidisciplinary approach to intervention. We retrospectively reviewed a cohort of patients with calciphylaxis at our institution. Those who underwent surgical debridement and wound closure were analysed with emphasis on wound healing, progression to amputation and mortality. Sixty-two patients with calciphylaxis underwent surgical debridement. Twenty patients had wound closure by skin grafting, five were excised with primary wound closure, and 37 were debrided and allowed to heal by secondary intention. There were excellent rates of healing in all groups, and no patients demonstrated wound progression or new lesions following operative intervention. Surgical debridement and wound closure are safe and effective in treating wounds related to calciphylaxis.
This retrospective study aimed to evaluate the clinical efficacy of double flap tibial transverse transport (dTTT) in the treatment of Wagner grade 3–4 diabetic foot ulcers (DFUs) and to assess its impact on peripheral nerve function in the affected limb. A total of 25 patients with DFUs who underwent dTTT at our institution were included. Baseline data were collected, and patients were systematically followed at 1, 3, 6 and 12 months postoperatively. Primary outcome measures included wound healing status, postoperative complications, microcirculatory indicators and nerve conduction parameters. All bone transport sites healed successfully, with no major complications observed except for one patient who died from COVID-19. At 12 months postoperatively, significant improvements were noted in foot skin temperature, transcutaneous oxygen partial pressure and the ankle-brachial index (all p < 0.001). Additionally, motor nerve conduction velocities of the posterior tibial and common peroneal nerves increased significantly (p < 0.001), and corresponding compound muscle action potential amplitudes rose to 4.91 ± 0.14 mV and 4.68 ± 0.29 mV, respectively (p < 0.001). These findings suggest that dTTT not only facilitates wound healing by improving local microcirculation but also enhances peripheral nerve function, offering a promising therapeutic approach for improving long-term outcomes and quality of life in patients with advanced DFUs.
Investigate the epidemiological characteristics of outpatients initially diagnosed with skin ulcers who were ultimately confirmed to have cutaneous malignant tumours, and provide a diagnostic and therapeutic basis for the occurrence of secondary diseases in chronic wounds. We conducted a retrospective study analysing clinical data from patients initially diagnosed with skin ulcers at our hospital between July 2021 and February 2025, and analysed the epidemiological characteristics of malignant transformation in these ulcer cases. Among 128 patients initially diagnosed with skin ulcers, 16 cases (12.5%) were confirmed with cutaneous malignancies. The malignant group had a significantly higher mean age (69.44 ± 11.30 years) compared to the non-malignant group (58.39 ± 17.88 years; t = 5.752, p = 0.01). The distribution of lesion sites differed significantly between the malignant and non-malignant groups (χ2 = 30.498, p < 0.01). In the malignant group, the head and neck (41.2%) and trunk & extremities (41.2%) were the predominant sites. The most common malignancy was squamous cell carcinoma (SCC). The trunk & extremities was the most frequent site (62.5%). The second was basal cell carcinoma, which mainly occurs in the head and neck (80.0%). The mean duration of ulceration was 4.5 years. The primary treatment modality was surgical excision (11 cases, 68.8%). Approximately one-seventh of skin ulcer cases were confirmed as cutaneous malignancies. This finding underscores the significance of skin ulcers as potential malignant lesions, highlighting the need for clinicians to maintain a high index of suspicion and promptly perform histopathological examinations to improve early detection rates of skin cancers.
