The role of teledermatology in Mohs micrographic surgery: a review.

This paper explores the role of teledermatology (TD) in Mohs micrographic surgery (MMS) at various stages of patient care. The study aims to assess the benefits, limitations, and patient experiences surrounding TD integration into MMS practices. We conducted a PubMed search using keywords related to TD and MMS, categorizing selected articles into pre-operative, intra-operative, and post-operative stages of MMS. TD reduced waiting times (26.10 days for TD compared to 60.57 days for face-to-face [FTF]) and consultation failure rates (6% for TD vs. 17% for FTF) for MMS preoperative consultations. It also shortened time to treatment by two weeks and led to notable travel savings (162.7 min, 144.5 miles, and $60.00 per person). Telepathology facilitated communication and decision-making during MMS, improving accuracy and efficiency, especially in challenging cases requiring collaboration where physical presence of another surgeon or pathologist is not feasible. Telepathology definitively diagnosed benign lesions and malignant tumors in 81.8% of cases (18/22). Additionally, there was a 95% agreement between conventional light microscopy diagnosis and telepathology in tumors (19/20), and 100% agreement for all 20 Mohs frozen section consultations. For post-operative follow-up, telephone follow-up (TFU) and text messaging proved effective, cost-efficient alternatives with high patient satisfaction (94% in New Zealand and 96% in the U.K.) and early complication identification. This study underscores TD's multifaceted benefits in MMS: enhanced patient experience preoperatively, improved communication during surgery, and cost-effective postoperative follow-up. Limitations include the financial expense and technical issues that can arise with TD (connectivity problems, delays in video/audio transmission, etc.). Further studies are needed to explore emerging TD modalities in post-operative patient management. The integration of TD into MMS signifies a progressive step in dermatological care, offering convenient, cost-effective, and better solutions with the potential to enhance patient experiences and outcomes.

Fillers impacting follicles: the emerging complication of filler-induced alopecia.

Filler-induced alopecia is a transient alopecia characterized by localized hair loss and often attributed to vascular compromise following dermal filler injections in facial regions. Although an uncommon phenomenon, the rising incidence of filler-induced alopecia underscores the importance of understanding and managing this condition. We performed an extensive PubMed review of articles reporting filler-induced alopecia and summarizing the implicated filler types, injection areas, hair loss patterns, symptom onset, course progression, treatments, and prognosis. Hyaluronic acid injections were the most implicated in filler-induced alopecia cases, with calcium hydroxylapatite and autologous fat less frequently associated. No cases involved other dermal filler types. Although recovery times varied depending on the treatment, hyaluronidase (HAase) injections rapidly restored near-normal hair density within 3-4 months. Minoxidil and platelet-rich plasma play a more minor role in restoring hair growth but may be used as adjuncts with HAase to facilitate hair growth. Finally, alternative interventions like intralesional triamcinolone, warm compresses, and nitroglycerin warrant exploration, given limited robust clinical data. Our study promotes awareness of filler-induced alopecia's rising incidence and offers practical insights and evidence-based recommendations for effective management. By equipping dermatologists with this knowledge, our aim is to improve patient outcomes and reduce adverse events in filler-based procedures.

Lasers in the management of alopecia: a review of established therapies and advances in treatment.

Alopecia, also known as hair loss, is a highly prevalent condition affecting millions of men and women in the United States and worldwide, making it one of the most common complaints by patients presenting to a dermatologist. The symptomology on the presentation of alopecia can be highly variable, ranging from diffuse thinning of hair, discrete and localized patches completely absent of hair, or noticing significant shedding when brushing and showering. Although alopecia does not have a direct negative health impact on patients, it is nonetheless a debilitating disease as it can profoundly impact an individual's self-image and psychosocial well-being. There are multiple treatment options available to patients with alopecia, and they are typically tailored to the patient's needs and preferences. The most common of these is the Food and Drug Administration-approved drugs for alopecia, minoxidil, and finasteride. However, both of these are known to be partially efficacious for all patients, so clinicians often use different modalities in conjunction with them, in particular laser-based therapies. This review article will provide a comprehensive assessment of lasers and other light therapies that may be used to manage the two most common types of alopecia: androgenetic alopecia and alopecia areata.

The Impact of Acculturation on Skin Cancer Risk and Protective Behaviors in Hispanic Populations.

The US Hispanic population faces rising skin cancer risks and poorer clinical outcomes, despite lower incidence rates. Acculturation, adopting elements of the dominant culture, may influence skin cancer attitudes and behaviors among Hispanics. We systematically reviewed PubMed articles from 2000 to 2023. Peer-reviewed English articles that assessed the relationship between acculturation and skin cancer in the Hispanic population were included. Andreeva et al. observed that lower acculturation levels correlated with increased use of shade and protective clothing (P < 0.05). More acculturated Latinos were more likely to use sunscreen, but this association weakened after adjusting for covariates (P > 0.48). Heckman et al. highlighted significant differences in skin cancer concern among Hispanic youth, with less acculturated individuals expressing greater worry (P < 0.05). Coups et al. found that higher acculturation was linked to less sun protective clothing usage and more frequent sunburns. Their subsequent online survey indicated that English-acculturated Hispanics engaged less in protective behaviors. Viola et al. reported that English-acculturated Hispanics perceived greater suntan benefits and had lower perceptions of skin cancer risk, severity, and concerns about photo-aging, along with higher melanoma risk factors, compared to Spanish-acculturated Hispanics. Acculturation influences skin cancer attitudes and behaviors in Hispanics. Tailored interventions based on acculturation levels are essential to reduce skin cancer risk. For example, educating English-acculturated Hispanics about skin cancer risks and prioritizing knowledge dissemination for Spanish-acculturated individuals may be effective approaches. These findings emphasize the need for targeted skin cancer prevention efforts to address disparities among US Hispanics.

Exploring the potential role for extended reality in Mohs micrographic surgery.

Mohs micrographic surgery (MMS) is a cornerstone of dermatological practice. Virtual reality (VR) and augmented reality (AR) technology, initially used for entertainment, have entered healthcare, offering real-time data overlaying a surgeon's view. This paper explores potential applications of VR and AR in MMS, emphasizing their advantages and limitations. We aim to identify research gaps to facilitate innovation in dermatological surgery. We conducted a PubMed search using the following: "augmented reality" OR "virtual reality" AND "Mohs" or "augmented reality" OR "virtual reality" AND "surgery." Inclusion criteria were peer-reviewed articles in English discussing these technologies in medical settings. We excluded non-peer-reviewed sources, non-English articles, and those not addressing these technologies in a medical context. VR alleviates patient anxiety and enhances patient satisfaction while serving as an educational tool. It also aids physicians by providing realistic surgical simulations. On the other hand, AR assists in real-time lesion analysis, optimizing incision planning, and refining margin control during surgery. Both of these technologies offer remote guidance for trainee residents, enabling real-time learning and oversight and facilitating synchronous teleconsultations. These technologies may transform dermatologic surgery, making it more accessible and efficient. However, further research is needed to validate their effectiveness, address potential challenges, and optimize seamless integration. All in all, AR and VR enhance real-world environments with digital data, offering real-time surgical guidance and medical insights. By exploring the potential integration of these technologies in MMS, our study identifies avenues for further research to thoroughly understand the role of these technologies to redefine dermatologic surgery, elevating precision, surgical outcomes, and patient experiences.

Trends in Mohs surgery fellowship directors.

The purpose of this study is to illustrate demographic trends among Mohs Micrographic Surgery (MMS) Fellowship Directors. Our search was constructed from the 2022 to 2023 Mohs Micrographic Surgery Fellowship Directory on the Accreditation Council for Graduate Medical Education (ACGME) website. Datapoints gathered included: age, sex, residency/fellowship training location, time since training completion until FD appointment, length in FD role, and personal research H-index. We identified 77 FDs, of which all 77 were included in this study. The mean age was 55.5 years; 55 (71.4%) were men and 20 (26.0%) were women. Most of the FDs who completed the survey did not self-report ethnicity or race, so these measures were not included. The top residency institutions that produced the most FDs were Cleveland Clinic (n = 4), Mayo Clinic (n = 4), New York University Medical Center (NYU, n = 4), and University of California-Los Angeles (UCLA, n = 4); the top fellowship institutions were NYU (n = 7), UCLA (n = 5), Cleveland Clinic (n = 4), and Geisinger Medical Center (n = 4). The mean H-index was 15.9, the mean number of peer-reviewed publications was 71, and the mean time from training completion until FD appointment was 10 years. Our results indicate that a majority of FDs are men (71.4%) and that FDs are more likely to have graduated from certain residency and fellowship programs.

Sebaceous carcinoma: an updated review of pathogenesis, diagnosis, and treatment options.

Sebaceous carcinoma (SC) is a very rare and aggressive form of skin cancer that arises from the sebaceous glands. SC can occur anywhere on the body, but most commonly affects the head and neck, especially the upper eyelid. SC is the third most common malignancy of the eyelid and has the potential to metastasize and be fatal; therefore, it is vital for dermatologists to remain acquainted with this malignancy and its most current treatment options. Most commonly presenting as a painless lump or thickening of skin on the eyelid, SC has an insidious progression that may not prompt the patient to seek medical attention immediately. To avoid the potential of metastasis, early diagnosis and treatment is paramount. To assess if the cancer has spread, ophthalmology, imaging, and sentinel lymph node biopsy are recommended. This article provides a comprehensive review of SC's pathogenesis, current diagnostic methods, and treatments, including wide local excision, Mohs micrographic surgery, orbital exenteration, radiation, and other topicals. The prognosis of SC depends on several factors, including size, location, stage, and treatment method. After treatment of the neoplasm, diligent post-treatment surveillance remains the cornerstone of patient care. Continued dermatologic follow-ups are essential for early detection of reoccurrence, ensuring timely intervention and optimal long-term outcomes. In conclusion, this comprehensive review aims to equip dermatologists and other physicians with a nuanced understanding of SC, enabling them to provide effective care to support patients encountering this malignancy.

The role of 755-nm alexandrite picosecond laser in melasma management.

Melasma is a skin dyspigmentation condition that disproportionately affects women, particularly those of Latino, Black, and Asian ethnicities, significantly impacting their quality of life. Efforts to identify effective treatment options have led to the exploration of picosecond laser technology which utilizes brief pulse durations to break down pigment while minimizing thermal damage to surrounding tissue. The 755-nm alexandrite picosecond laser, currently FDA approved for benign pigmented lesion removal, including melasma, is a promising solution. We aim to assess the efficacy and safety of the 755-nm alexandrite picosecond laser both as a stand-alone treatment for melasma and in combination with topical agents. We conducted a PubMed search using "755-nm picosecond" AND "melasma," "755-nm picosecond" AND "hydroquinone," and "755-nm picosecond" AND "tranexamic acid." English-written studies examining this laser as monotherapy or in combination with the topical agents were included. Those not meeting the criteria or lacking data related to melasma improvement were excluded. Monotherapy with the 755-nm picosecond laser led to a 50-75% improvement in melasma appearance in 40% of participants and a significant reduction in the average Melasma Area and Severity Index (MASI) score (p < 0.001) in all patients of one study. Notably, the use of topical tranexamic acid (TTA) in conjunction with the picosecond laser exhibited the most significant degree of improvement in hemi-MASI scores compared to the laser monotherapy group at one- and three-months post-treatment (p < 0.05). Patient satisfaction was also significantly higher for the combination group (p < 0.05). In contrast, combining hydroquinone (HQ) with the picosecond laser demonstrated no significant difference in outcomes compared to HQ alone, both of which were less effective than TTA with picosecond laser. The combination of the 755-nm picosecond laser with TTA proves promising, outperforming both laser monotherapy and laser with HQ. While monotherapy with the picosecond laser or topical agents is effective, literature favors combination therapy, especially the 755-nm picosecond laser with TTA, for superior benefits and minimal side effects. Ultimately, individualized regimens, considering factors like skin type, should be prioritized, given the heightened risk of postinflammatory hyperpigmentation, especially in skin of color patients.

The top 100 most cited Mohs micrographic surgery articles: an analysis of Altmetrics data from 2010 to 2020.

With skin cancer rates rising, there is a consistent stream of literature published on Mohs micrographic surgery (MMS). However, there are no studies examining MMS article visibility and readership patterns. The Altmetric Attention Score (AAS) is a metric that quantifies article distribution on media platforms. We analyzed the 100 most cited MMS publications from 2010 to 2020 and constructed multivariate regression models using top 25th percentile AASs and mentions on Facebook, Twitter, and new outlets as outcome variables. Articles with an AAS in the top 25th quartile consistently performed better with higher citations, Twitter mentions, Facebook mentions, and journal impact factors compared to articles in the lower three quartiles (53.8 vs 33.9; 4.68 vs 0.44; 0.32 vs 0.08; 53.5 vs 14.6; p < 0.05 for all). There were significantly lower female last authors versus males in the top quartile of AAS articles, with males 142 times more likely to have articles in the top quartile (p < 0.05). Studies comparing MMS to other surgical techniques and funded articles had higher odds of being in the top quartile of AASs (aOR 29.63 p < 0.05; aOR 74.50 p < 0.05). AASs can be useful to understand public interest, readership, and article features that influence the reach of MMS literature.

A review of heart transplant immunosuppressants and nonmelanoma skin cancer.

Heart transplant recipients experience high rates of skin cancer, likely due to greater length or dosage of immunosuppression. We review the impact of immunosuppressive medications on development of nonmelanoma skin cancer (NMSC) in heart transplant recipients. The authors searched keywords "heart transplant" and "nonmelanoma skin cancer" on PubMed in October 2022 for eligible articles available in English. Articles were selected for inclusion based on relevance to heart transplantation and NMSC. If any cited articles within included articles were related to our search they were also included. Of the 29 identified articles, 18 met the inclusion criteria with a total of 11,699 patients. Two studies found that tacrolimus and azathioprine increased the risk of NMSC. Five studies demonstrated that tacrolimus, everolimus, sirolimus, azathioprine and mycophenolate mofetil decreased the risk of NMSC. Three studies described that cyclosporine, tacrolimus, everolimus, sirolimus, azathioprine, mycophenolate mofetil and prednisone had no significant association with the development in NMSC. Two studies did not specify the correlation between immunosuppressant use and NMSC development. Ten studies did not discuss the association of immunosuppressants use with the development of NMSC. Our review highlights the commonly used immunosuppressive drugs that can impact the development of NMSC in heart transplant recipients. A management strategy in immunosuppression-associated skin cancers may ultimately involve adjusting the immunosuppressive regimen. This review serves as a summary of the most commonly used immunosuppressive drugs in heart transplant patients and their tumorigenic mechanisms to guide recommendations for dermatologic follow-up in heart transplant recipients.

A review of treatment of port-wine stains with pulsed dye laser in fitzpatrick skin type IV-VI.

Port-Wine Stains are a congenital vascular malformation that affect 0.3-0.5% of newborns. It is a benign capillary malformation that commonly occurs on the head and neck. It is formed by progressive dilation of the post-capillary venules, and as the patient ages it may be associated with hypertrophy and nodularity which can lead to cosmetic disfigurement and psychological aggravation. There are many choices of treatment such as cryosurgery, cosmetic tattooing, and dermabrasion, amongst others. The treatment of choice is pulse dye laser (PDL) because it is both effective and safe to use. In darker skin types (Fitzpatrick skin types IV-VI), treatment is more difficult. Caution when treating darker skin types with PDL comes from the fact that there is an inverse correlation between vessel specificity of the PDL and skin pigmentation. In this review, we will be reviewing the literature and discussing the manuscripts that describe the treatment of PWS on patients with fitzpatrick skin type IV-VI. Authors searched the PubMed Medline in the English language from database inception through December 2022 for eligible articles. The keywords searched included "PDL," "pulse dye laser," "skin of color," "Fitzpatrick skin types IV-VI," "fitzpatrick," "pigmented skin," "Port-wine stain," "PWS", and "pulse dye laser." The articles that were included discussed PDL in the treatment of PWS in patients of skin of color. Any additional similar articles that were cited in our search were also included. Articles that were excluded did not discuss Fitzpatrick skin types IV-VI, darker skin type, or PDL. Data collected from each article included the number of participants, Fitzpatrick skin type, age, and laser parameters. There were 120 articles that were reviewed from our search and a total of nine articles met inclusion criteria with 241 patients that were considered Fitzpatrick skin type IV-VI. The patients were of a wide range of ages from 1 month to 74 years old. In our review, patients who are treated at a younger age had better results than when treated at an older age. The results show that darker skin individuals have better results when treated at a younger age compared to adults, they can experience complete resolution. Adults who were treated saw a variation of results, from improvements in the appearance to hyperpigmentation/hypopigmentation or scarring of the treated area. Patients who are Fitzpatrick skin type IV-VI are at higher risk of adverse events when treated with PDL for PWS when compared to patients of other skin types. Studies show that PDL can be beneficial for PWS in patients of skin of color; however, there are risks of hyperpigmentation, hypopigmentation, and scarring that are important to take into consideration when treating these patients. Further research is warranted to improve the understanding of PDL for PWS in patients of skin of color.

Investigating the burden of cardiovascular comorbidities in inpatient non-melanoma skin cancer outcomes.

While cardiovascular comorbidities can affect the outcomes of a variety of conditions, to our knowledge, few studies have evaluated their impact on non-melanoma skin cancers (NMSC). We studied the National Inpatient Sample to evaluate the impact of cardiovascular comorbidities on NMSC hospitalizations. Our findings displayed higher cost of care (Beta 5053; SE 1150; P < 0.001), length of stay (Beta 1.8; SE 0.394; P < 0.001), and mortality (aOR 2.51; CI 1.49-4.21; P < 0.001) in patients with NMSC who had an associated cardiovascular comorbidity. Specifically, patients with cerebrovascular disease (aOR 3.52; CI 1.18-10.5; P = 0.024), heart failure (aOR 4.02; CI 2.29-7.05; P < 0.001), complicated hypertension (OR 2.05; CI 1.16-3.61; P = 0.013), and pulmonary circulation disease (aOR 3.33; CI 1.13-9.78; P = 0.029) demonstrated greater odds of mortality.
