{"title":"Intradermal Tranexamic Acid Injections: A Potential Therapy for Complex Cases of Drug-Induced Postinflammatory Hyperpigmentation","authors":"Juan He,&nbsp;Shinan Hou,&nbsp;Yi Yang","doi":"10.1111/jocd.70061","DOIUrl":"https://doi.org/10.1111/jocd.70061","url":null,"abstract":"&lt;p&gt;Generally, postinflammatory hyperpigmentation (PIH) from fixed drug eruptions (FDE) can resolve spontaneously [&lt;span&gt;1&lt;/span&gt;]. However, various underlying factors may impede this process. Here, we present a complex patient with severe perioral hyperpigmentation due to FDE, who showed marked improvement after six sessions of intradermal tranexamic acid (TXA) injections.&lt;/p&gt;&lt;p&gt;A 50-year-old female patient presented with a 1-year persistent hyperpigmentation on her lips and perioral area after repeatedly taking Ibuprofen to manage fever during the COVID-19 pandemic. The pigmentation worsened with continued use of the medication (Figure 1A). Despite discontinuing ibuprofen and using topical hydroquinone and tretinoin for over 6 months, her hyperpigmentation became even more severe. A diagnosis of PIH caused by FDE was made. After discussing with her, we advised strict sun protection and avoidance of physical irritation of the lips. Additionally, we introduced intradermal injections of TXA due to its anti-inflammatory and anti-melanin-producing properties. The TXA solution was prepared by diluting 0.2 mL of a 500 mg/5 mL ampoule in sterile water to a 10 mg/mL concentration, yielding a total of 2 mL. The injections were administered intradermally at a 15°–20° angle, targeting the superficial dermis and creating small semicircular wheals. During each session, 0.1 mL doses were injected 5 mm apart across 14 sites, totaling 1.4 mL per session. After six monthly TXA sessions, the patient's perioral hyperpigmentation showed significant improvement (Figure 1B).&lt;/p&gt;&lt;p&gt;The type IV hypersensitivity reaction caused by FDE leads to damage to keratinocytes and melanocytes. Following drug withdrawal, dermal macrophages then phagocytize extravasated melanin, causing persistent PIH [&lt;span&gt;1&lt;/span&gt;]. Basically, PIH from FDE is self-limiting [&lt;span&gt;1&lt;/span&gt;]. However, in this case, the patient's hyperpigmentation not only failed to resolve but also worsened progressively after treatment. Hence, we considered there were additional factors that contributed to her atypical progression. First, her lesion is located on the lip, an area exposed to UV radiation and friction from eating. Second, she was in her perimenopausal period, also with skin type IV—a combination of skin type and fluctuating hormones that likely exacerbated her hyperpigmentation. Third, we can find that she also had melasma (Figure 1A), indicating a preexisting pigment metabolism abnormality. Collectively, factors such as UV exposure, mechanical friction, skin type, hormonal changes, and pigment metabolism issues likely intensified the pigmentation [&lt;span&gt;2&lt;/span&gt;]. Therefore, for this patient, discontinuing the offending drug alone was insufficient; effective anti-inflammatory and antipigment treatments were necessary to counteract these ongoing factors contributing to persistent hyperpigmentation.&lt;/p&gt;&lt;p&gt;Topical treatments, such as retinoids, hydroxy acids, and broad-spectrum photoprotection, are th","PeriodicalId":15546,"journal":{"name":"Journal of Cosmetic Dermatology","volume":"24 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jocd.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Large Language Models in Cosmetic Dermatology","authors":"Marina Landau,&nbsp;George Kroumpouzos,&nbsp;Mohamad Goldust","doi":"10.1111/jocd.70044","DOIUrl":"https://doi.org/10.1111/jocd.70044","url":null,"abstract":"&lt;p&gt;Artificial intelligence (AI), particularly large language models (LLMs) like ChatGPT and Gemini, is expanding healthcare, specifically in the field of cosmetic dermatology. These advanced AI systems are designed to process and generate human-like text by analyzing vast amounts of data. Through natural language processing (NLP), LLMs offer innovative solutions that improve patient care, facilitate clinical workflows, and accelerate research efforts. However, while these models hold significant potential, it is crucial to address their limitations, as well as the ethical considerations and regulatory challenges associated with their use, to ensure responsible implementation [&lt;span&gt;1, 2&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;At their core, LLMs are sophisticated computer programs capable of understanding and generating human-like text. Imagine conversing with a knowledgeable assistant who can quickly summarize medical research, suggest treatment options, or answer complex questions. LLMs achieve this by learning patterns from extensive datasets, including books, articles, and scientific journals. With this training, they can synthesize information and provide coherent responses to user inquiries [&lt;span&gt;3&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;LLMs are expanding several aspects of cosmetic dermatology. One key application lies in patient education. By simplifying complex medical terminology, LLMs make cosmetic procedures, such as dermal fillers, neurotoxins, and laser therapies, more accessible to patients. This improved communication enables patients to make informed decisions about their care. Additionally, these tools have the potential to bridge knowledge gaps in underserved communities, although challenges like limited digital proficiency and internet access still persist.&lt;/p&gt;&lt;p&gt;Another critical application is personalized treatment planning. LLMs can analyze patient histories, procedural risks, and desired outcomes to provide evidence-based recommendations. For instance, they may suggest combining microneedling with platelet-rich plasma therapy to achieve optimal skin rejuvenation. While this personalization can enhance treatment outcomes, it requires clinician oversight to ensure that recommendations match individual patient needs and are free from bias.&lt;/p&gt;&lt;p&gt;LLMs also contribute to administrative efficiency in dermatology practices. Integrating these tools into electronic medical record (EMR) systems can automate tasks such as clinical note-taking, scheduling, and insurance coding. This automation reduces administrative burdens, allowing clinicians to devote more time to direct patient care [&lt;span&gt;4&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Follow-up care and monitoring are additional areas where LLMs show efficiency. These models can interact with patients' postprocedure, ensuring adherence to recovery protocols, identifying potential complications, and assessing satisfaction levels. These capabilities enhance continuity of care and provide valuable feedback for clinicians to improve their services.&lt;/p&gt;&lt;p&gt;In tr","PeriodicalId":15546,"journal":{"name":"Journal of Cosmetic Dermatology","volume":"24 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jocd.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
