Social media platforms are changing the way health care professionals interact with patients, especially the younger, millennial population. This new mode of communication provides unique marketing opportunities to reach younger generations, primarily via Facebook, Instagram, YouTube, Snapchat, and TikTok. These platforms have already become primary mechanisms by which entertainment, news, and information are consumed, shared, and disseminated in this age group. It is important to understand these evolving dynamics to take full advantage of the opportunities that these platforms confer for creating and executing marketing strategy for dermatologists and clinics., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2023 Elsevier Inc.

Purpose: Heterotopic ossification (HO) formed over the major components and fixation screw heads of an alloplastic temporomandibular joint replacement (TMJR) prosthesis can result in decreased quality of life, limited function, prosthesis failure, and hinder prosthesis revision, replacement, or removal. This study simulated HO removal from the major components and fixation screw heads of alloplastic TMJR prostheses using an erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser and compared the results to conventional methods of HO removal. The surface morphology and chemical structure of the exposed components were analyzed. The investigators hypothesize that HO removal with an Er,Cr:YSGG laser causes less damage to TMJR prosthesis components compared to conventional HO removal methods., Methods: This multiple test descriptive analysis simulated HO removal from TMJR prostheses mounted to stereolithic models. Simulated HO removal was completed using a novel Er,Cr:YSGG laser method and conventional methods which utilized a fissure carbide bur in a high-speed rotary instrument, a standard osteotome, and an ultrasonic aspirator. Surfaces exposed on the TMJR prostheses were analyzed for morphological or chemical change using scanning electron microscopy, energy dispersive X-ray spectroscopy, and Raman spectroscopy., Results: The Er,Cr:YSGG laser did not adversely affect the titanium screws or titanium components of the TMJR prostheses, while conventional methods of HO removal did. HO removal using the Er,Cr:YSGG laser and conventional methods both inflicted surface damage to the fossa ultrahigh molecular weight polyethylene component of the TMJR prostheses., Conclusion: Damage inflicted to titanium alloy or commercially pure titanium components of TMJR prostheses by conventional HO removal methods can be avoided by instead removing HO with an Er,Cr:YSGG laser. However, long exposure of the Er,Cr:YSGG laser to ultrahigh molecular weight polyethylene surfaces should be avoided. Additional research to expand on applications to other procedures and in other surgical fields is encouraged., (Copyright © 2022 American Association of Oral and Maxillofacial Surgeons.

Platelet-rich plasma (PRP) has expanded its therapeutic applications into the field of aesthetic medicine. PRP is an autologous blood-derived product with an increased concentration of platelets to plasma relative to that of whole blood, which supports its therapeutic effects. Frequently promoted and marketed directly to consumers and patients, clinicians are often questioned on the efficacy and safety of PRP as a therapeutic modality. Given the rise in popularity of PRP, multiple clinical trials have been conducted to assess its application within the field of aesthetic medicine, particularly for hair loss conditions, skin rejuvenation, scarring, and conditions of dyspigmentation. We have reviewed the relevant research about the utility of PRP and associated evidence-based practices and discuss the direction for future research., (Copyright © 2021 Elsevier Ltd.

Background: Melasma is a chronic pigmentary condition that can have significant negative effects on quality of life. Vitamin C can be effective in the treatment melasma, but its delivery often proves to be challenging due to instability of the drug and subsequent cutaneous irritation at higher concentrations., Aim: In this prospective, open-label, evaluator-blinded study, we aimed to assess the efficacy and tolerability of twice-daily application of a novel, highly potent, non-irritating 30% tetrahexyldecyl (THD) ascorbate serum in combination with 100% mineral-based sunscreen in the treatment of melasma during the summer months., Patients/methods: Ten female subjects of ages ranging from 18 to 60 years underwent twice-daily application of 30% THD ascorbate serum in combination with an anti-aging 100% mineral tinted broad-spectrum protection SPF 45 sunscreen moisturizer for 12 weeks during the summer months (July to September). Two blinded evaluators scored baseline and post-treatment photographs using the Griffiths' 10-point scale and global aesthetic improvement scale., Results: All subjects showed an improvement in hyperpigmentation with an average improvement of 33.7%. Seventy percent of subjects showed an improvement in skin tone evenness (redness), and among those subjects, the average improvement was 33.3%. The median global aesthetic improvement score was 2.0 (very much improved)., Conclusion: Our study demonstrated efficacy and safety in treating the pigmentary as well as vascular components of melasma with a novel 30% THD ascorbate serum and a purely mineral-based tinted moisturizing sunscreen., (© 2020 Wiley Periodicals LLC.)

Miniplate osteosynthesis has revolutionised the treatment of open reduction and internal fixation in craniomaxillofacial procedures. However, when complications arise necessitating the removal of previously placed miniplates, bony overgrowth may be present and must be eliminated before removal of the hardware is possible. Osteogenesis over the screws prevents proper engagement of the screwdriver with the screw drives. If bone remains embedded in the screw drive during attempted removal of the screw, the contact interference increases the risk of the screwdriver slipping and the screw drive being stripped. There remains a lack of adequate techniques to clear bony overgrowth from miniplates and screws to allow for easy removal, as conventional methods are ineffective, time-consuming, and may damage the screw drives. Herein, we describe a new laser-assisted miniplate removal technique to eliminate bone that has grown over miniplates and screws before the miniplate is removed. This technique is efficient, safe, and simple and, compared with conventional methods, may decrease the complications associated with the removal of miniplates and screws., (Copyright © 2020 The British Association of Oral and Maxillofacial Surgeons.

Background: It is known that malignant melanoma (MM) survivors are at increased risk of future primary MM. However, the risk for noncutaneous second primary malignancies (SPMs) is not as well-understood., Methods: An observational study utilizing data from the Surveillance, Epidemiology, and End Results (SEER) database was performed, assessing data from patients diagnosed with primary cutaneous MM to measure overall, as well as specific, tumor type and risk of SPM., Results: Of the 132,438 patients recruited in the study population (mean age 55.5 years; 54% male), 23,794 SPMs were observed (O) (18% of patients at a mean age of 68.8 years), while 17,923 SPMs were expected (E) to occur (O : E 1.33, 95% CI 1.31-1.34). Excluding cutaneous MM occurring as a new primary malignancy, there was a significantly increased risk for SPMs among cutaneous MM survivors for each of the following tumor types: eye and orbit melanoma, tracheal, thyroid, salivary gland, retroperitoneum, small intestine, kidney, lymphoid and hematopoietic system, lymphoma overall, non-Hodgkin lymphoma, lymphocytic leukemia overall, chronic lymphocytic leukemia, male genital system (including prostate), and breast. Certain gender-specific trends for SPMs were also detected., Conclusions: Patients with primary cutaneous MM are at increased risk for primary noncutaneous MM as well as noncutaneous SPMs that include numerous tumor types. Enhanced oncologic surveillance for a variety of tumor types in melanoma survivors is warranted., (© 2020 The International Society of Dermatology.)

Sebaceous carcinoma (SC) is a potentially aggressive malignancy of periocular or extraocular skin. It arises sporadically or is associated with Muir-Torre syndrome (MTS). Here, we review three controversial clinical conundra related to the diagnosis and treatment of SC and offer evidence-based recommendations. First, following a diagnosis of SC, deciding which patients to screen for MTS can be challenging. The Mayo MTS Risk Score is a clinical score that incorporates the key cutaneous findings in MTS but relies heavily on personal and family history that may not be available at the time of SC diagnosis, especially in young patients. Young patients, who have extraocular SC and are suspected to have MTS though do not meet criteria by Mayo MTS Risk Score, should have their tumors tested using immunohistochemistry for mismatch repair proteins. Second, sentinel lymph node biopsy (SLNB) is used in periocular SC to evaluate nodal disease. Patient selection is critical for SLNB. Periocular SC stage ≥ T2c (by American Joint Commission on Cancer, 8th edition) may be considered for SLNB given positivity rates over fifteen percent in expert hands. Lastly, treatment of metastatic SC is an area of active investigation. When possible, tumor profiling may be used to select targeted agents. Future research into these three key questions is needed.

Sebaceous carcinoma usually occurs in adults older than 60 years, on the eyelid, head and neck, and trunk. In this Review, we present clinical care recommendations for sebaceous carcinoma, which were developed as a result of an expert panel evaluation of the findings of a systematic review. Key conclusions were drawn and recommendations made for diagnosis, first-line treatment, radiotherapy, and post-treatment care. For diagnosis, we concluded that deep biopsy is often required; furthermore, differential diagnoses that mimic the condition can be excluded with special histological stains. For treatment, the recommended first-line therapy is surgical removal, followed by margin assessment of the peripheral and deep tissue edges; conjunctival mapping biopsies can facilitate surgical planning. Radiotherapy can be considered for cases with nerve or lymph node involvement, and as the primary treatment in patients who are ineligible for surgery. Post-treatment clinical examination should occur every 6 months for at least 3 years. No specific systemic therapies for advanced disease can be recommended, but targeted therapies and immunotherapies are being developed., (Copyright © 2019 Elsevier Ltd. All rights reserved.)
