Abstract

Nevus comedonicus is an extremely rare adnexal hamartoma of pilosebaceous apparatus, with approximately 200 cases reported in the literature so far. It appears as cluster of adjacent honeycomb-like dillated follicular openings with firm pigmented keratin plugs resembling comedones.The comedones oftentimes arranged in linear pattern paralled to Blaschko’s lines. We report a case of a 5-year-old boy with open brown to black comedones in a linear pattern localized on the back of the left thigh that appearing since birth. Pain, itch and discharge were not obtain. There were some episodes of infection, due to manual removal done by his mother which left some hypertrophic scars. Dermoscopic examination revealed the distinctive pattern consisting of pigmented, sharply demarcated keratin plugs of 1-3 mm in diameter, some open pores, multiple structurless, various shades of brown homogenous circular areas surrounding the plugs. Histopathological examination showed an aggregation of dilated follicular infundibulum with laminated keratinous material plugging. This case report prove that dermoscopy examination, a simple non-invasive diagnostic tool is very helpful in diagnosing nevus comedonicus. We recommend this tool to differentiate the diagnosis of other rare epidermal nevi while histopathological examination should be performed only in uncertain cases.

Abstract

Penuaan kulit merupakan akumulasi berbagai perubahan progresif yang terjadi pada sel dan jaringan kulit. Kulit manusia terdiri matriks ekstraseluler (MES) dermal dengan protein penyusunnya adalah kolagen. Selama penuaan, kolagen tipe I mengalami perubahan organisasi dan struktural, penurunan sintesis protein MES, dan terjadi peningkatan degradasi metaloproteinase mengakibatkan hilangnya kekuatan mekanik. Studi menunjukkan peran penurunan fungsi penghalang kulit terkait usia dalam penuaan pada tikus. Tujuan penelitian ini untuk mengetahui deposisi kolagen tipe I berdasarkan usia pada jaringan kulit tikus Wistar. Desain penelitian merupakan observasional analitik cross-sectional. Penelitian menggunakan tikus Wistar yang telah memenuhi kriteria inklusi dan eksklusi. Tikus dikelompokkan menjadi kelompok usia 3 bulan, 6 bulan, 12 bulan, dan 18 bulan. Pengambilan jaringan kulit dengan biopsi plong dilanjutkan pembuatan preparat dengan pewarnaan Trichome masson. Perhitungan deposisi kolagen dilakukan pada area berwarna biru dan diinterpretasikan (%) menggunakan software ImageJ. Rerata persentase deposisi kolagen terbesar pada kelompok usia 3 bulan dengan nilai 57,6±0,17% dan 57,5±0,43% pada pembesaran 40x dan 100x. Persentase deposisi kolagen terendah terdapat pada kelompok usia 18 bulan dengan nilai 12,1±1,6% dan 6,9±0,52% pada pembesaran 40x dan 100x. Pada penelitian ini dapat disimpulkan bahwa terdapat penurunan deposisi kolagen jaringan kulit tikus Wistar seiring dengan pertambahan usia akibat proses penuaan, dengan deposisi kolagen jaringan kulit tikus Wistar kelompok usia muda lebih besar dibandingkan kelompok usia yang lebih tua.

Abstract

Introduction: In silico analysis is used in the early stages of drug discovery to speed the rate of discovery that is considered cost and time-efficient. Virgin Coconut Oil (VCO) is a treatment option for atopic dermatitis because it has function to repair skin barrier and as anti-inflammation. Objective: To evaluate the VCO content using computational in silico analysis for the treatment of atopic dermatitis. Methods: The active compounds of Cocos nucifera extracted from KNApSAcK database were predicted experimentally and analyzed computationally using Simple Molecular-Input Line-Entry System (SMILES), Prediction of Activity Spectra for biologically active Substances (PASS) server, and Search Tool for Interactions of Chemicals (STITCH). Results: There are 19 active compounds found in VCO. The analysis shows that VCO has free fatty acid (FFA) protein which acts as a receptor for long and medium chain saturated and unsaturated fatty acids. The highest potential bioactivity of active VCO compounds was as antieczema, with the most important component was linoleic acid, with an average value of probable to be active (Pa) = 0.872, predicted to be highly potential in computational and laboratory tests. Conclusion: Based on this study, we recommend the use of VCO as treatment for atopic dermatitis because VCO has anti-inflammatory potential bioactivity, histamine inhibitor, improves skin barrier function and antieczema which could improve the outcome of atopic dermatitis.

Abstract

Introduction: Pyoderma gangrenosum (PG) is a rare inflammatory disease characterized by sterile, predominantly neutrophilic infiltration of the skin and other organs. PG is found particularly in women aged between 40-60 years. Metabolic syndrome is reported to have a potential role to induce PG. Case: A 45-year-old woman came to Dr. Moewardi Hospital with chief complaints of ulcer in the chest and legs that was preceded by reddish fluid filled bump which then broke into painful wound. History of trauma, gastrointestinal, and joint pain was denied. Dermatological examination of anterior trunk region and inferior extremity showed erythematous patches with multiple ulcers with irregular border covered with hemorrhagic crusts and necrotic tissue. Pathergy test was negative. In the right and left axillary, inframammary and inguinal, there were hyperpigmented patches with scales and satellite lesions, KOH 10% examination obtained pseudohyphae and cell budding. The patient also has metabolic syndrome. Diagnosis of PG was made based on the presence of 2 major and 2 minor criteria. Patient was given intravenous methylprednisolone 93.75 mg/24 hours, analgesics, antibiotics, topical antifungals, debridement and breast reconstructive surgery after response to steroid therapy was seen. The patient was discharges from hospital with improvement. Discussion: Metabolic syndrome is considered to be a risk factor contributing to the development of systemic chronic inflammatory processes and has been described as one of the precipitating factors for PG and skin candidiasis. Management of metabolic syndrome as the known risk factor aims to minimize the recurrence of PG in the future.

Abstract

Phototherapy is a non-ionizing ultraviolet (UV) radiation therapy used as a treatment for several medical conditions. The mechanism of action of phototherapy is to act as antiproliferative, induce apoptotic, and provide immunosuppressive effect. Several therapeutic modalities that can be used as alternative therapy in children include NB-UVB, BB-UVB, ultraviolet A, PUVA, and excimer laser. Phototherapy in children is indicated especially in diseases such as psoriasis, atopic dermatitis, vitiligo, pityriasis lichenoides, and mycoses fungoides. The use of phototherapy has indications, contraindications, dose, and side effects that should be considered when choosing appropriate phototherapy in children. Common side effects are erythema, xerosis, burning sensation, and itching. Several groups of patients with refractory complaints are advised to use additional phototherapy modalities, either as monotherapy or in combination with topical and systemic therapy.

Abstract

Background: Sexually transmitted infections (STIs) remain a significant public health concern globally, with millions of new cases occurring annually. Understanding the prevalence and risk factors associated with STIs is crucial for effective prevention and control programs. This study aimed to investigate the prevalence and risk factors of STIs among patients attending the Dermatology and Venereology Outpatient Clinic of Dr. Moewardi General Hospital, a tertiary hospital in Surakarta, Indonesia. Methods: A retrospective descriptive study was conducted using secondary data from medical records of patients diagnosed with STIs between January 2020 and December 2023. Data collected included sociodemographic characteristics, sexual behaviors, clinical diagnoses, and HIV status. Descriptive statistics and chi-square analysis were used to analyze the data. Results: A total of 249 patients were diagnosed with STIs during the study period. The most common STI was condyloma acuminata (51%), followed by male genital discharge (18.1%), female vaginal discharge (16%), other STIs (10.9%), and genital ulcers (4%). The majority of patients were male (62.2%), aged 25-44 years (49.1%), had a high school education (49.5%), and reported heterosexual orientation (67.1%). Multiple sexual partners were reported by 62.7% of the participants, and 36.1% were HIV positive. The correlation analysis reveals that various sociodemographic, behavioral, and health-related factors are associated with different STIs. Conclusion: Condyloma acuminata was the most prevalent STI among patients attending the Dermatology and Venereology Outpatient Clinic of Dr. Moewardi General Hospital. The correlation analysis reveals that various sociodemographic, behavioral, and health-related factors are associated with different STIs. Understanding these correlations can help healthcare providers identify individuals at higher risk for specific STIs and implement targeted prevention and intervention strategies. Targeted interventions focusing on these high-risk groups are needed to reduce the burden of STIs in Surakarta, Indonesia.

Abstract

Background: The therapeutic armamentarium for androgenetic alopecia (AGA) is limited, with variable efficacy and potential side effects associated with standard treatments like minoxidil. Platelet-rich plasma-derived exosomes (PRP-Exo) represent a novel acellular strategy, offering a concentrated payload of regenerative biomolecules. This study aimed to rigorously evaluate the therapeutic efficacy and underlying mechanisms of PRP-Exo, as a monotherapy and in combination with minoxidil, in a validated murine model of AGA. Methods: A parallel-group, randomized, double-blind, controlled experimental study was conducted. Thirty-two male C57BL/6 mice with testosterone-induced AGA were randomized (n=8/group) to one of four groups: Negative Control (NC), Positive Control (PC; 5% topical minoxidil), Treatment 1 (T1; intradermal PRP-Exo), or Treatment 2 (T2; combination of PRP-Exo and minoxidil). PRP-Exo were characterized by Transmission Electron Microscopy, Nanoparticle Tracking Analysis, and ELISA for marker proteins. After a 14-day treatment period, efficacy was assessed via hair follicle density (HFD), anagen-to-telogen (A/T) ratio, and hair shaft thickness. Mechanistic insight was obtained by quantifying tissue protein levels of Ki-67 and β-catenin by ELISA. Results: All active treatments significantly improved hair regeneration compared to the NC group. The combination therapy (T2) demonstrated the most profound effects across all metrics, showing statistically superior outcomes compared to both minoxidil (PC) and PRP-Exo (T1) monotherapies in HFD (65.8 ± 12.1 vs. 36.2 ± 8.5 and 47.3 ± 10.4 follicles/mm², respectively; p<0.01). Furthermore, T2 treatment led to the highest A/T ratio and hair shaft thickness. ELISA revealed that T2 treatment also resulted in the highest tissue concentrations of the proliferation marker Ki-67 and the Wnt pathway protein β-catenin, suggesting enhanced mitogenic activity and modulation of key developmental pathways. Conclusion: PRP-Exo is a potent hair regenerative agent, significantly outperforming minoxidil in this preclinical model. The combination of PRP-Exo and minoxidil exhibits a synergistic effect, promoting superior follicular regeneration by concurrently stimulating tissue proliferation and upregulating key components of the anagen-promoting Wnt signaling pathway. These findings underscore the significant clinical potential of PRP-Exo as a next-generation therapy for AGA.

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.
