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

Background: Pemphigus foliaceus (PF) is a rare autoimmune blistering disease characterized by superficial, fragile blisters. Psoriasis vulgaris, a chronic inflammatory skin condition, has been rarely associated with PF. This case report presents an unusual instance of PF developing in a patient with a history of psoriasis vulgaris. Case presentation: A 54-year-old Indonesian woman presented with a one-year history of scaly skin and reddish spots across her body, worsening over the past week. She had a prior diagnosis of psoriasis vulgaris and was undergoing methotrexate therapy (15 mg/week) without significant improvement. Three months prior, she developed loose blisters on her back that spread to her hands, rupturing easily and leaving painful sores. The patient denied any mucosal involvement. One week before her presentation, her symptoms worsened following relocation-related stress. Dermatological examination revealed generalized multiple erythematous patches with scales, some with ruptured blisters leaving erosions, and a positive Nikolsky sign. Histopathological examination confirmed PF. The patient was treated with intravenous methylprednisolone, oral erythromycin and paracetamol, topical mupirocin, and clobetasol. After one month, due to a lack of improvement, azathioprine was added, leading to lesion improvement without side effects. Conclusion: This case highlights the rare but potential development of PF in patients with psoriasis vulgaris. The complex interplay between these two conditions warrants further investigation. Early diagnosis and appropriate treatment are crucial for managing PF and improving patient outcomes.

Abstract

Background: Deep mycosis, a spectrum of invasive fungal infections affecting deeper tissues, poses significant diagnostic and therapeutic challenges, particularly in tropical regions like Central Java, Indonesia. This study aimed to investigate the epidemiological trends, occupational risk factors, and diagnostic challenges associated with deep mycosis in this region. Methods: A retrospective study was conducted at a single center, Dr. Moewardi General Hospital, in Central Java, Indonesia, analyzing medical records of patients diagnosed with deep mycosis between 2019 and 2024. Data on demographics, occupation, clinical presentation, diagnostic methods, and treatment outcomes were collected and analyzed. Results: A total of 12 cases of deep mycosis were identified. The majority of patients were male (75%) and engaged in agricultural activities (50%). Chromoblastomycosis (66.7%) and maduromycosis (25%) were the most common clinical diagnoses. Diagnostic delays were frequent (mean delay: 5.1 months), primarily due to non-specific clinical presentations and limited access to diagnostic facilities. Conclusion: Deep mycosis predominantly affects individuals involved in agriculture in Central Java, highlighting the need for enhanced awareness and preventive strategies among high-risk occupational groups. Improved diagnostic facilities and healthcare infrastructure are crucial for timely diagnosis and effective management of deep mycosis in resource-constrained settings.

Abstract

Background: Vitiligo is a complex autoimmune depigmenting disorder driven by melanocyte-specific CD8+ T cells, oxidative stress, and genetic susceptibility. The lack of standardized, accessible animal models that recapitulate these pathways hinders therapeutic development. This study aimed to systematically optimize and validate a chemically-induced vitiligo model in C57BL/6 mice. Methods: Eighty (80) male C57BL/6 mice were randomized into ten groups (n=8/group). Experimental groups received once-daily topical applications of hydroquinone (HQ) at 2.5%, 5%, or 10%, or monobenzone (MBZ) at 40% for 8 or 16 days. Vehicle-treated mice served as controls. Efficacy was assessed via quantitative histopathology (Masson-Fontana staining for melanin area), biomolecular assays for oxidative stress (Malondialdehyde [MDA] and Superoxide Dismutase [SOD]), and RT-qPCR for melanogenesis-related (Tyr) and inflammation-related (Tnf) gene expression. Results: A clear dose- and time-dependent depigmentation was observed. The 10% HQ 16-day protocol was maximally effective, inducing a profound reduction in epidermal melanin area (0.06 ± 0.02) compared to 16-day controls (0.40 ± 0.04; p < 0.001). This histopathological finding was significantly correlated with severe cutaneous oxidative stress, evidenced by a 3.75-fold increase in MDA (p < 0.001) and a 50% reduction in SOD activity (p < 0.001) versus controls. Furthermore, this regimen caused a potent suppression of Tyr expression (0.15-fold change; p < 0.001) and a significant upregulation of the pro-inflammatory cytokine Tnf (3.8-fold change; p < 0.001). Conclusion: The 16-day topical application of 10% hydroquinone is a reliable, rapid, and highly reproducible protocol for inducing vitiligo-like depigmentation in C57BL/6 mice. This model successfully recapitulates key pathophysiological pillars of human vitiligo, including melanocytotoxicity, profound oxidative stress, and a pro-inflammatory cutaneous environment, establishing it as a valuable platform for preclinical therapeutic screening.

Abstract

Curcuma longa (turmeric) is a medicinal plant widely used for its anti-inflammatory, antioxidant, and antimicrobial properties. Cream formulations are ideal for topical delivery due to their ease of application, good absorption, and patient acceptability. The maceration method is a simple and cost-effective technique for obtaining plant extracts without compromising bioactive compounds. This study aimed to evaluate the physical stability of a cream formulation containing 5% Curcuma longa extract prepared using the maceration extraction method. The extract was prepared through maceration of dried turmeric rhizome using ethanol, followed by evaporation to obtain the concentrated extract. The cream was formulated with stearic acid, cera alba, vaselin album, triethanolamine, propylene glycol, and distilled water as base components. Physical stability parameters were tested over seven days, including pH, dispersion, and adhesion tests. Statistical analysis was performed using the Friedman test. The pH values ranged from 7.33 to 7.50 (p = 0.006), indicating mild alkalinity but remaining within an acceptable range for topical application. Dispersion remained stable throughout the observation period (p = 0.452), while adhesion increased significantly from 182.71 to 200.04 seconds (p = 0.006), suggesting improved cohesiveness. The 5% Curcuma longa extract cream demonstrated good physical stability, indicating that the maceration method is a viable approach for developing stable topical herbal formulations.
