BACKGROUND AND OBJECTIVES:The keystone design perforator island flap (KDPIF) is often used to cover defects in reliable blood supply and similar skin patterns, but its mobility is limited, especially when the wound is large or occurs around joints. Here, we describe a modified KDPIF, boat-shaped flap. We added a V shape along the lateral arc, forming a V-Y flap on KDPIF's outer arc shapes like a sail. This paper also describes a clinical study to evaluate this method. METHOD:From September 2014 to March 2017, 31 patients were operated on using the boat-shaped flap in our department and were followed up annually with clinical evaluation. The wound locations included joints (n = 11), trunk (n = 18), and face (n = 2). Fifteen defects were ≥5 × 5 cm2 . RESULTS:After 6 to 24 months of follow-up, 29 patients had first-intention healing and were satisfied with the morphology and function. Secondary healing was observed in two patients, and the wounds were closed after dressing treatment for 2 weeks. CONCLUSION:The boat-shaped flap enhances the mobility and achieves strong resistance to tension. The modified curvilinear shape prevents the joint activity from being restricted, with visually concealed scars. It is particularly applicable for repairing large wounds and defects around joints.


背景与目的: keystone设计穿支岛状皮瓣 (KDPIF) 常被用于覆盖血供可靠、皮肤形态相似的缺损,但其活动度有限,特别是当伤口较大或发生在关节周围时。在这里,我们描述了一种改良的KDPIF,船形皮瓣。我们沿侧弧添加了一个V形,在KDPIF的外弧形状上形成一个V-Y瓣,像帆一样。本文还描述了一个临床研究来评价这种方法。 方法: 2014 年 9 月-2017 年 3 月,我科对 31 例患者采用舟形皮瓣进行手术治疗,并进行年度随访和临床评价。伤口位置包括关节 (n = 11) 、躯干 (n = 18) 和面部 (n = 2)。15 例缺损 ≥ 5 × 5 cm2。 结果: 经过 6 ~ 24 个月的随访,29 例患者均获得 ⅰ 期愈合,形态和功能满意。观察 2 例患者二次愈合情况,换药治疗 2 周后伤口闭合。 结论: 舟形皮瓣增强了活动度,达到了较强的抗张力能力。修改后的曲线形状防止关节活动受到限制,视觉上隐藏疤痕。特别适用于关节周围较大的创伤和缺损的修复。

METHODS::Blue rubber bleb naevus syndrome (BRBNS) is an extremely rare venous malformation that often manifests as multiple haemangioma-like lesions in the skin and gastrointestinal tract. The drug sirolimus plays a key role in the signalling pathway of angiogenesis and subsequent development of BRBNS and its use has been described in several case reports. We present a case series of four patients with BRBNS who exhibited good treatment response to sirolimus. All four patients were administered oral sirolimus at doses of 1.0-1.5 mg/m2 /day with a target drug level of 5-10 ng/mL and median treatment duration of 20 months. All patients had a reduction in the size of the lesions and a normalization of coagulopathy with tolerable drug adverse reactions at follow-up. Sirolimus may be effective and safe in paediatric patients with BRBNS. Further prospective studies are suggested to evaluate the long-term effectiveness of this drug.

METHODS:BACKGROUND:Human papillomavirus (HPV) infections are associated with common dermatologic and nondermatologic diseases. Although HPV vaccines are well established as preventive measures for genital warts and cervical neoplasia, their use as therapeutic agents deserves greater attention. OBJECTIVE:To evaluate the use of HPV vaccine(s) as a treatment modality for cutaneous and/or mucosal disease. METHODS:A primary literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted in January 2019 by using the PubMed and Cochrane databases. RESULTS:A total of 63 articles with 4439 patients were included. The majority of patients with cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas were successfully treated with HPV vaccination. Preliminary data on patients with pre-existing anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia is promising. LIMITATIONS:This review was limited by the lack of controls, patients' previous HPV vaccination status, and publication bias. CONCLUSION:The commercially available three-dose, quadrivalent HPV vaccine is a potential therapeutic option for the treatment of cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas. Noncommercially available HPV vaccines demonstrate therapeutic response for treating anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia. The vaccine's efficacy as an adjunct therapy for HPV-associated cutaneous and/or mucosal disease warrants further exploration.

METHODS::Our understanding of melanoma precursors and progression to melanoma has developed as a result of advances in the field of molecular diagnostics. We now better understand the potential for genetic heterogeneity within a single lesion. Combined tumors can pose a diagnostic challenge when deciding the line between benign and malignant, which in turn has direct implications for patient management. Primary cilia (PC) are ubiquitous sensory organelles that have essential functions in cellular proliferation, differentiation, and development. The ciliation index (percentage of ciliated melanocytes) has been shown to reliably differentiate melanoma, which fail to ciliate, from melanocytic nevi, which retain PC. We therefore analyzed the potential for using the ciliation index to differentiate benign and malignant components in combined melanocytic lesions. We collected patient samples (n = 10) of unequivocal combined lesions with both melanoma and associated nevus components. Melanocytes were highlighted with SOX10 and costained with gamma-Tubulin and acetylated alpha-Tubulin to highlight the basal body and cilium, respectively. The number of melanocytes retaining cilia under high-power microscopy was examined. The melanoma component had average of 4% ciliation (SD: 7%), whereas the associated nevus component was significantly higher with 59% ciliation (SD: 17%). These data show that PC may be a reliable means of distinguishing benign from malignant components within a single tumor. The ciliation index may be a helpful tool in distinguishing challenging cases of combined lesions of melanoma in situ with a dermal nevus component from invasive melanoma, thus promoting improved staging and clinical management.
