BACKGROUND:Dermatologists overall perform a large number of procedures billed to Medicare, though the proportion of surgical procedures attributable to general dermatologists who do not perform Mohs micrographic dermatologic surgery (MDS) is unknown. OBJECTIVE:To determine the surgical volume of dermatologists who do not perform MDS and compare it to the surgical volume of MDS-performing dermatologists and all non-dermatologists. METHODS:A cross-sectional analytical study was performed using the Medicare public use file for 2014. Data were divided by physician specialty (dermatologists vs all non-dermatologists), and dermatologists were then dichotomized by MDS performance. RESULTS:Non-MDS dermatologists performed 42.19% of the benign excisions, 57.18% of the malignant excisions, and 46.00% of the intermediate repairs billed to Medicare in 2014. Micrographic dermatologic surgery-performing dermatologists were responsible for most of the complex repairs (67.56%), flaps (52.85%), and grafts (59.65%) billed to Medicare. CONCLUSION:Dermatologists who do not perform MDS represent the single largest group billing Medicare for benign excisions, malignant excisions, and intermediate repairs. They also bill for more complex repairs than all non-dermatologists combined. Micrographic dermatologic surgery-performing dermatologists performed most of the complex repairs, flaps, and grafts billed to Medicare.


背景: 皮肤科医生总体上执行了大量按医疗保险收费的手术,尽管不执行Mohs显微照相皮肤手术 (MDS) 的普通皮肤科医生的手术比例尚不清楚。 目的: 确定不执行MDS的皮肤科医生的手术量,并与执行MDS的皮肤科医生和所有非皮肤科医生的手术量进行比较。 方法: 采用医疗保险公共使用档案对 2014 进行横断面分析研究。按医师专科 (皮肤科医师vs所有非皮肤科医师) 划分数据,然后按MDS表现进行二分法。 结果: 非MDS皮肤科医生在 2014 年进行了 42.19% 的良性切除、 57.18% 的恶性切除和 46.00% 的医疗保险中期修复。显微照片皮肤科手术-执行皮肤科医生负责大部分复杂修复 (67.56%) 、皮瓣 (52.85%) 和移植物 (59.65%),费用由医疗保险支付。 结论: 不进行MDS的皮肤科医生代表了良性切除、恶性切除和中间修复的单一最大的组计费医疗保险。他们还比所有非皮肤科医生加起来还要复杂的修复费用。显微照片皮肤外科-执行皮肤科医生进行了大部分复杂的修复、皮瓣和移植物,费用由医疗保险支付。

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.
