ABSTRACT
BACKGROUND: Malignant melanoma in-situ, lentigo maligna (MMIS-LM) can be successfully treated with several different surgical techniques; however, the literature is inconsistent in defining them. OBJECTIVE: To comprehensively define and describe the national guideline recommended surgical techniques used to treat MMIS-LM to help clarify and standardize this terminology to ensure compliance with the guidelines. METHODS: A targeted literature review was performed from 1990 to 2022 focusing on articles that discussed the national guideline recommended surgical techniques of wide local excision, Mohs micrographic surgery (MMS), modified Mohs surgery, and staged excision/Slow-Mohs for MMIS-LM, as well as the related methods of tissue processing. National Comprehensive Cancer Network and American Academy of Dermatology guidelines were reviewed to identify how the techniques need to be employed to be compliant with guideline recommendations. RESULTS: We describe the various surgical and tissue processing techniques and discuss advantages and disadvantages of each. LIMITATIONS: This paper was styled as a narrative review defining and clarifying terminology and technique and does not investigate these topics more broadly. CONCLUSION: Understanding the methodology and terminology for these surgical procedures and tissue processing methods is critical so that both general dermatologists and surgeons can employ these techniques effectively for optimal patient care.

BACKGROUND: Medical spas have experienced a recent rise in popularity. However, rules and regulations vary nationwide. Given the number of complications attributable to medical spas, questions remain about currently regulatory practices and whether they are sufficient to protect patients from harm. OBJECTIVE: Our study investigated the current state of medical spas and their associated patient complications in the aesthetic field as well as the experiences and attitudes of practitioners. MATERIALS AND METHODS: A survey was distributed to current members of the American Society for Dermatologic Surgery. RESULTS: Of all cosmetic complications encountered in the past 2 years, the majority reported that the percentage of complications seen in their practice attributable to medical spas ranged from 61% to 100%. The most commonly cited complications from medical spas were burn, discoloration, and misplacement of product, whereas the most commonly cited treatments resulting in complications were fillers, intense pulsed light, and laser hair removal. For safety and outcomes, medical spas were rated as inferior to physician-based practices. CONCLUSION: Patient complications associated with medical spas are not uncommon. Overall, practitioners believe medical spas are endangering to patient safety, think that stricter rules and regulations are necessary, and request more support from the specialty medical societies.

BACKGROUND: Severe acute malnutrition contributes to 1 million deaths among children annually. Adding routine antibiotic agents to nutritional therapy may increase recovery rates and decrease mortality among children with severe acute malnutrition treated in the community. METHODS: In this randomized, double-blind, placebo-controlled trial, we randomly assigned Malawian children, 6 to 59 months of age, with severe acute malnutrition to receive amoxicillin, cefdinir, or placebo for 7 days in addition to ready-to-use therapeutic food for the outpatient treatment of uncomplicated severe acute malnutrition. The primary outcomes were the rate of nutritional recovery and the mortality rate. RESULTS: A total of 2767 children with severe acute malnutrition were enrolled. In the amoxicillin, cefdinir, and placebo groups, 88.7%, 90.9%, and 85.1% of the children recovered, respectively (relative risk of treatment failure with placebo vs. amoxicillin, 1.32; 95% confidence interval [CI], 1.04 to 1.68; relative risk with placebo vs. cefdinir, 1.64; 95% CI, 1.27 to 2.11). The mortality rates for the three groups were 4.8%, 4.1%, and 7.4%, respectively (relative risk of death with placebo vs. amoxicillin, 1.55; 95% CI, 1.07 to 2.24; relative risk with placebo vs. cefdinir, 1.80; 95% CI, 1.22 to 2.64). Among children who recovered, the rate of weight gain was increased among those who received antibiotics. No interaction between type of severe acute malnutrition and intervention group was observed for either the rate of nutritional recovery or the mortality rate. CONCLUSIONS: The addition of antibiotics to therapeutic regimens for uncomplicated severe acute malnutrition was associated with a significant improvement in recovery and mortality rates.

BACKGROUND: Published appropriate use criteria (AUC) for Mohs micrographic surgery (MMS) for melanoma are based on consensus opinion. OBJECTIVE: To evaluate whether published AUC identify melanomas for which MMS may benefit patients by detecting subclinical spread or confirming clear microscopic margins before flap or graft reconstruction. MATERIALS AND METHODS: Retrospective cohort study of 591 melanomas in 556 patients evaluating the correlation between current AUC (anatomic location, recurrent status, and tumor stage) and subclinical spread or reconstruction with a flap or graft. RESULTS: Anatomic location on the head, neck, genitalia, hands, feet, or pretibial leg was associated with a significantly higher frequency of subclinical spread (odds ratio (OR) 1.89, p = .0280) and flap or graft reconstruction (OR 10.3, p = .0001). Compared with primary lesions, recurrent melanomas had a higher frequency of subclinical spread (OR 1.78, p = .0104) and reconstruction with a flap or graft (OR 1.67, p = .0217). The frequencies of subclinical spread and flap or graft reconstruction did not differ between in situ and invasive melanomas. CONCLUSION: Anatomic location and recurrent status are useful criteria to identify melanomas that may benefit from MMS. Tumor stage is not a useful criterion, as MMS has similar benefits for subsets of both invasive and in situ melanomas.

BACKGROUND: Various methods of tissue processing have been used to treat melanoma with Mohs micrographic surgery (MMS). OBJECTIVE: We describe a method of treating melanoma with MMS that combines breadloaf frozen sectioning of the central debulking excision with complete peripheral and deep microscopic margin evaluation, allowing detection of upstaging and comprehensive pathologic margin assessment before reconstruction. METHODS: We conducted a retrospective cohort study evaluating for local recurrence and upstaging in 614 invasive or in situ melanomas in 577 patients treated with this MMS tissue processing methodology using frozen sections with melanoma antigen recognized by T cells 1 (MART-1) immunostaining. Follow-up was available in 597 melanomas in 563 patients. RESULTS: Local recurrence was identified in 0.34% (2/597) lesions with a mean follow-up time of 1026 days (2.8 years). Upstaging occurred in 34 of 614 lesions (5.5%), of which 97% (33/34) were detected by the Mohs surgeon before reconstruction. LIMITATIONS: Limitations include retrospective study, intermediate follow-up time, and that the recurrence status of 39.6% of patients was self-reported. CONCLUSION: Treating melanoma with MMS that combines breadloaf sectioning of the central debulking excision with complete peripheral and deep microscopic margin evaluation permits identification of upstaging and consideration of sentinel lymph node biopsy before definitive reconstruction and achieves low local recurrence rates compared with conventional excision.

Localized changes in cutaneous elastic tissue often manifest with flesh-colored, hypopigmented, or yellow papules, plaques, and nodules. We present five children with clinically similar cobblestone plaques composed of multiple hypopigmented, nonfollicular, pinpoint papules located unilaterally over the upper chest. All lesions first appeared at birth or during early infancy. No associated extracutaneous abnormalities have been identified. Histopathology was remarkable for many, thick elastic fibers with elastorrhexis. We believe that these cases represent a distinct and unique variant of connective tissue nevi.

OBJECTIVE: The primary aim of this study was to describe the prevalence of select oncogenic viruses within vulvar squamous cell carcinoma (VSCC) and their association with human immunodeficiency virus (HIV) status in women in Botswana, where the national HIV prevalence is the third highest in the world. METHODS: A cross-sectional study of biopsy-confirmed VSCC specimens and corresponding clinical data was conducted in Gaborone, Botswana. Polymerase chain reaction (PCR) and immunohistochemistry (IHC) viral testing were done for Epstein-Barr virus, human papillomavirus (HPV) strains, and Kaposi sarcoma herpesvirus, and PCR viral testing alone was done for John Cunningham virus. RESULTS: Human papillomavirus prevalence by PCR was 100% (35/35) among tested samples. Human papillomavirus type 16 was the most prevalent HPV strain (82.9% by PCR, 94.7% by either PCR or IHC). Kaposi sarcoma herpesvirus prevalence by PCR had a significant association with HIV status (P = 0.013), but not by IHC (P = 0.650). CONCLUSIONS: The high burden of HPV, specifically HPV16, in vulvar squamous cell cancer in Botswana suggests a distinct HPV profile that differs from other studied populations, which provides increased motivation for HPV vaccination efforts. Oncogenic viruses Kaposi sarcoma herpesvirus and Epstein-Barr virus were also more prevalent in our study population, although their potential role in vulvar squamous cell cancer pathology is unclear.
