Abstract

Background: Ultraviolet B (UVB) radiation is a primary driver of cutaneous hyperpigmentation disorders, with oxidative stress recognized as a key pathogenic mechanism. However, a comprehensive, multi-level characterization of the causal link between chronic UVB exposure and the resulting oxidative, histological, and melanogenic responses is needed. This study aimed to quantitatively validate a preclinical model of UVB-induced hyperpigmentation by characterizing the reciprocal regulation of key oxidative stress biomarkers and correlating these changes with objective histological evidence of hyperpigmentation. Methods: This controlled in vivo experimental study used 14 male Sprague Dawley rats, divided into a control group (KN; n=7) and a UVB-exposed group (KP; n=7). The KP group received chronic UVB radiation (300 mJ/cm² daily, 5 days/week for 4 weeks). Dorsal skin tissue was harvested for analysis. Oxidative stress was assessed by quantifying malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) levels via ELISA. Hyperpigmentation was objectively validated and quantified using Fontana-Masson staining for melanin deposition and immunohistochemistry for microphthalmia-associated transcription factor (MITF). Results: Chronic UVB exposure induced significant hyperpigmentation, confirmed by a 5.8-fold increase in epidermal melanin content (p < 0.001) and a 4.1-fold increase in the number of MITF-positive melanocytes (p < 0.001) in the KP group. This was accompanied by a profound oxidative imbalance: MDA levels increased by 7.5-fold (p < 0.001), while the activities of SOD, CAT, and GPx decreased by 80.5%, 65.2%, and 71.4%, respectively (all p < 0.001). A strong negative correlation was observed between MDA and all antioxidant enzymes, particularly SOD (r = -0.985, p < 0.001). Conclusion: Chronic UVB exposure directly triggers a collapse of the cutaneous antioxidant network, leading to severe lipid peroxidation. This state of profound oxidative stress is causally linked to melanocyte activation and excessive melanin synthesis, driving the hyperpigmentation phenotype. This robustly validated preclinical model provides a powerful platform for investigating the molecular pathophysiology of UVB-induced pigmentary disorders and for evaluating novel therapeutic interventions.

Abstract

Latar Belakang: Nevus Unius Lateris (NUL) adalah kelainan bawaan jaringan kulit langka, ditandai distribusi lesi unilateral mengikuti garis Blaschko. Lesi ditemukan pada tahun pertama kehidupan dengan bercak coklat kekuningan, batas yang jelas, dan permukaan verukosa. Pemeriksaan multidisiplin dianjurkan untuk menegakkan diagnosis dan memberikan penatalaksanaan yang tepat. Terapi bertujuan untuk mengangkat dan menghancurkan lesi hiperkeratosis dengan pembedahan/non-pembedahan. Elektrokauter dapat menjadi pilihan untuk membantu mencegah perdarahan setelah operasi dermatologis, terutama hemofilia. Kasus: Tn. A, 24 tahun, pekerjaan wiraswasta, datang dengan keluhan utama beberapa plak yang meninggi di belakang lehernya. Keluhan pertama muncul sebagai bintik pada usia 6 tahun dan naik perlahan, dan menyebar luas. Pasien memiliki riwayat hemofilia A. Pemeriksaan dermatologis, beberapa nodul verukosa hiperpigmentasi bertangkai dengan batas teratur, garis yang jelas tersusun secara linier mengikuti garis Blaschko di daerah coli posterior. Hasil pemeriksaan dermoskopi menunjukkan pola sirkular hiperpigmentasi dengan struktur epidermis eksofitik dan pola serebriform. Pemeriksaan histopatologi menunjukkan hiperkeratosis, akantosis, papilomatosis minimal, dan deposit melanin dengan kepadatan ringan-sedang. Pasien didiagnosis dengan nevus unius lateris dan diterapi bedah listrik. Pasien diberikan antibiotik sistemik oral dan analgesik selama lima hari setelah prosedur dan disarankan untuk kontrol pada hari ketiga, dan pengangkatan jahitan dilakukan pada hari ketujuh. Kesimpulan: Beberapa perawatan medis dan bedah telah dicoba, tetapi tidak ada pengobatan yang ideal atau dapat diterima secara universal. Namun, kekambuhan dapat terjadi berbulan-bulan atau bertahun-tahun setelah pengangkatan lesi dengan metode apa pun. Terapi dengan bedah listrik dapat dipilih untuk membantu mencegah perdarahan yang mungkin terjadi setelah prosedur melalui target hemostasis dan untuk kerusakan jaringan superfisial.

Abstract

Background: Pyoderma gangrenosum (PG) is a rare necrotic ulcerative skin disease, often associated with an underlying systemic condition. Bacterial coinfection in PG can worsen the course of the disease and slow healing. Case presentation: We report the case of a 25-year-old woman with PG of her left leg complicated by Pseudomonas aeruginosa co-infection. The patient had a history of poorly treated psoriasis. The diagnosis is made based on disease history, physical examination, microbiological examination, and histopathological examination. The patient was treated with oral levofloxacin and topical combination therapy of astaxanthin and platelet-rich plasma (PRP) with wound debridement. Significant clinical improvement was achieved within six weeks. Conclusion: PG with bacterial coinfection requires appropriate diagnosis and treatment to achieve optimal results. Topical therapy combining astaxanthin and PRP with wound debridement proved effective in this case.

Abstract

Verruca vulgaris (VV), a cutaneous disorder associated with human papillomavirus (HPV), presents as a benign proliferation of keratinocytes. Verruca vulgaris therapy with destructive methods such as trichloroacetic acid (TCA) and electrocautery is the most commonly used therapeutic modality. The study aims to assess the therapeutic efficacy and clinical benefit of trichloroacetic acid (TCA) and electrosurgery in managing VV by synthesising evidence from clinical studies or case series. Systematic review adhered to the guidelines outlined in the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). To ensure the collection of accurate and relevant information, literature searches were conducted across PubMed, Google Scholar and Cochrane Library covering publications from 2014 to 2023. Twelve studies were included, comprising eight articles on TCA and four articles on electrosurgery. Trichloroacetic acid achieved a maximum cure rate of 93.3% while electrosurgery reached 100%. During six-month follow-up period, TCA showed no recurrence (0%), whereas electrosurgery had a recurrence rate of 21,9%. Electrocautery has more advantages than TCA with a higher cure rate. Even though it has a higher cure rate, electrocautery has a higher recurrence rate with more severe side effects than TCA.

Abstract

Latar belakang: Ulkus kronis pada ekstremitas bawah salah satunya yaitu ulkus venosum. Ulkus venosum didefinisikan sebagai lesi terbuka antara sendi lutut dan pergelangan kaki yang terjadi karena penyakit vena. Tantangan dalam mengobati VLU adalah kekambuhan yang sering terjadi maka terapi luka tingkat lanjut harus dipertimbangkan. Platelet rich plasma (PRP) sebagai terapi adjuvan pengobatan ulkus venosum dan menunjukkan hasil yang menjanjikan. Kasus: Seorang laki-laki berusia 55 tahun dengan keluhan luka yang sulit sembuh sejak dua tahun yang lalu. Pemeriksaan status dermatovenereologi pada regio ekstremitas inferior desktra nampak ulkus multipel dengan ukuran terbesar 9 cm x 5 cm x 0.5 cm, dengan dasar eritem dan serum tanpa disertai pus, nekrosis, nekrotik dan darah. Pasien memiliki riwayat hipertensi dan obesitas derajat II dengan Indeks Masa Tubuh (IMT) 44,29. Pasien diberikan terapi Platelet Rich Plasma (PRP) setiap tujuh hari, Kompres luka dengan cairan NaCl 0,9% selama 10 menit dilanjutkan dengan mupirosin 2% salep dan ditutup dengan menggunakan plester hidrokoloid yang dilakukan per 24 jam. Evaluasi pada minggu ke-6 terapi PRP, pasien menunjukkan adanya perbaikan klinis pada luka. Diskusi: Kandungan PRP terdiri dari banyak faktor pertumbuhan untuk mempercepat penyembuhan luka dan angiogenesis. Trombosit mengandung faktor pertumbuhan yang memicu efek biologis yang merupakan kunci dalam proses perbaikan dan regenerasi jaringan.
