Phenotype and genotype correlation of inherited epidermolysis bullosa in Indonesia.

BACKGROUND: Inherited epidermolysis bullosa (EB) is a group of genodermatoses with considerable clinical and genetic heterogeneity. Clinical diagnosis of the EB subtypes is frequently imprecise and requires confirmation with genetic testing. There is still limited study using genetic testing to identify EB subtypes in Indonesia. This study aims to identify the pathogenic variants of inherited EB patients at the Department of Dermatology and Venereology, Universitas Padjadjaran-Dr Hasan Sadikin General Hospital in Bandung, West Java, Indonesia and to describe the correlation between the phenotype and genotype of our patients. METHODS: Twelve patients clinically diagnosed with EB were included in this study. Genetic testing was performed in collaboration with KK Women's and Children's Hospital, Singapore. RESULTS: Pathogenic variants were identified in the COL7A1 gene in seven patients, namely Dominant Dystrophic EB (DDEB) with mutation types c.5945G>T, c.6218G>A, Recessive Dystrophic EB (RDEB) c.2005C>T, c.6081dup, c.1268C>T, c.1784C>T which are all known mutations. Novel mutations were found in the COL7A1 gene in two patients namely DDEB c.6253G>T and RDEB c.6740C>T. Two EB Simplex (EBS) patients showed mutation KRT14 gene as c.356T>C, c.373C>T which are known mutation. In addition, a novel mutation in LAMA3 gene c.2649del was found in one Junctional EB (JEB) patient. CONCLUSION: The molecular diagnoses of 12 Indonesian EB patients were identified, of which three were novel pathogenic variants. Concordance between the initial clinical diagnosis and genetic testing was only 33%. This demonstrated the importance of early genetic testing for accurate diagnosis, prognostication, management and genetic counselling.

Challenging diagnosis of leprosy in a psychotic homeless patient with atypical clinical manifestations: an interesting case report.

BACKGROUND: A decision to diagnose certain skin diseases in patient undergoing psychotic break is challenging; this includes establishing the diagnosis of leprosy. Diagnosis of leprosy is established if there is at least one of the three cardinal signs of leprosy. Histopathological examination is not a gold standard, but remains useful in atypical or clinically suspicious cases. CASE PRESENTATION: We report for the first time, an interesting case of leprosy with atypical clinical manifestations in a psychotic homeless male with unknown history of present illness. Upon examination, hypopigmented macules, hyperpigmented macules, and plaques were observed, with unclear sensation impairment. Peripheral nerve thickening and acid-fast bacilli from slit-skin smear were not found. Histopathological examination from hypopigmented macule on the upper right limb showed no granulomatous reaction and other histopathological features of leprosy. Although the condition did not fulfill the cardinal signs of leprosy, we found lagophthalmos, claw hands, pseudomutilation of fingers and toes. Therefore, the diagnosis of suspected leprosy was established. The patient was hospitalized and attempts to administer oral rifampicin and clofazimine were made. Several days after treatment, annular erythematous macules appeared on the patient's face, abdomen, and back. Histopathological examination results on sample taken from erythematous macule and right sural nerve were consistent with the diagnosis of leprosy with reversal reaction. CONCLUSION: In certain conditions, histopathological examination of the skin and nerves are a highly rewarding test in establishing a diagnosis of leprosy.

Optimizing ultraviolet B radiation exposure to prevent vitamin D deficiency among pregnant women in the tropical zone: report from cohort study on vitamin D status and its impact during pregnancy in Indonesia.

BACKGROUND: Vitamin D deficiency during pregnancy carries potential threat to fetal well being. Natural conversion of vitamin D in the skin can be facilitated by direct ultra violet B (UVB) radiation, but the effect is reduced by wearing umbrellas, clothes, or sunblock cream. Muslim women wear hijab that allows only face and hands to be seen. With increasing proportion of muslim women wearing hijab and the lack of vitamin D fortification and fish consumption in Indonesia, it poses a problem for vitamin D deficiency among pregnant women. This study aimed at finding the best timing of UVB exposure and the duration of exposure which can be suggested to prevent vitamin D deficiency among pregnant women, for those wearing hijab or not. METHODS: This study recruited 304 pregnant women in the first trimester, 75-76 women from 4 cities of the most populated province, West Java, Indonesia which represented 70-80% percent of pregnancy per year. A 3-day notes on duration, time and type of outdoor activity and the clothing wore by the women were collected. UVB intensity radiation were obtained. Calculation on body surface area exposed to direct UVB radiation and UVB radiation intensity were done. Measurement of vitamin D level in sera were done on the same week. RESULTS: The median of maternal sera vitamin D level was 13.6 ng/mL and the mean exposed area was around 0.48 m2 or 18.59% of total body surface area. Radiation intensity reached its peak around 10.00 and 13.00, but the mean duration of exposure to UVB during this window was lower than expected. Significant correlation was found between maternal sera vitamin D level and exposed body surface area (r = 0.36, p < 0.002) or percentage of exposed body surface (r = 0.39, p < 0.001) and radiation intensity (r = 0.15, p = 0.029). Further analysis showed that duration of exposure to UVB should be longer for pregnant women wearing hijab as compared to women without hijab. CONCLUSION: This study suggested that the best timing to get UVB exposure was between 10.00-13.00, with longer duration for women wearing hijab (64.5 vs 37.5 min) of continuous exposure per day.

Clinical efficacy of biocellulose, carboxymethyl cellulose and normal saline dressing in epidermolysis bullosa.

OBJECTIVE: To evaluate the efficacy of a biocellulose, a carboxymethyl cellulose and a normal saline wound dressing in the wound care management of epidermolysis bullosa (EB) skin wounds. METHODS: This was a single-blind, randomised controlled trial involving wounds from patients with EB. Wounds were divided into three groups: group I with biocellulose wound dressing, group II with carboxymethyl cellulose wound dressing and group III with normal saline wound dressing as a control. All dressing changes and wound parameters were recorded. Observations were conducted every three days until complete wound closure or up to one month. RESULTS: The outcomes of treatment of 36 wounds from four patients were evaluated in this study. Mean healing time in group I was seven days, eight days in group II and 14 days in group III. There were significant differences in healing times between group I and group III (p=0.0001) and between group II and III (p=0.001). The results showed a significant reduction in the percentage of wounds area on day three for each group: 51.7% in group I, 51.9% in group II, and 26% for group III. All wounds in groups I and II had healed at day 12 (100%) and at day 24 (100%) in group III. There were significant differences in the reduction of percentage wound area between group I and group III at day three (p=0.044) and day six (p=0.000), and between group II and III at day six (p=0.003). CONCLUSION: The study demonstrates that both the biocellulose and the carboxymethyl cellulose wound dressings significantly reduced percentage wound areas and complete healing times compared with the normal saline wound dressing in EB skin wounds, demonstrating they are both equally good for wound care management in EB patients.

Interleukin-18 correlates with interleukin-4 but not interferon-γ production in lymphocyte cultures from atopic dermatitis patients after staphylococcal enterotoxin B stimulation.

BACKGROUND: Staphylococcus aureus (S. aureus) triggers exacerbation of atopic dermatitis (AD) and causes chronic inflammation through the action of various proteins such as staphylococcal enterotoxin B (SEB). SEB has a role in activating interleukin (IL)-18, an important regulator of interferon (IFN)-γ and IL-4, in regards to a therapeutic strategy. OBJECTIVE: To determine the correlation of IL-18 level with the IL-4 and IFN-γ level in lymphocyte cultures from AD patients following SEB stimulation. METHOD: Twenty patients with AD based on the Hanifin and Rajka criteria and 20 healthy subjects as a control group were selected. A 5 ml blood sample from each subject was taken for lymphocyte culture. The culture was stimulated with SEB for two days and the outcomes were assessed by enzyme-linked immunosorbent assays (ELISA) to evaluate the levels of IL-18, IL-4, and IFN-γ. RESULTS: In the AD group, the levels of IL-18, IL-4, and IFN-γ in lymphocyte cultures with SEB were significantly increased compared with non-SEB exposed cells (each p<0.001); similar results were found in the control group. The level of IL-18 was significantly elevated in lymphocyte cultures with SEB stimulation in AD vs. control (p<0.05) and without SEB in AD vs. control (p<0.05). Furthermore, IL-18 levels were significantly correlated with IL-4 levels and score atopic dermatitis (SCORAD) values in AD patients with SEB (r=0.41, p<0.05; and r=0.70, p<0.05, respectively); on the in contrary, there was no correlation between IL-18 and IFN-γ levels (p=0.469). CONCLUSIONS: Our results suggest that IL-18 is correlated with increased of IL-4 levels in SEB-stimulated AD lymphocyte cultures.

Efficacy and Safety Profile of Tuberculin Protein Purified Derivative Injection As Immunotherapy For the Treatment of Cutaneous and Anogenital Warts: A Review Article.

Introduction: Various treatments available today for anogenital and cutaneous warts have limitations, including time-consuming, challenging to perform, and the risk of scarring. A new treatment using tuberculin purified protein derivative (PPD) has been developed, which is expected to generate cellular immunity against HPV. Objective: To assess the evidence for the efficacy and safety of PPD treatment for cutaneous and anogenital warts. Materials and methods: A literature search was performed with the keyword-based search on digital libraries, including the National Library of Medicine, Cochrane Controlled Register of Trial, and Google Scholar, using the following terms: anogenital warts, condyloma acuminata, cutaneous warts, human papillomavirus, immunotherapy, and tuberculin purified protein derivative. Original studies on treating cutaneous or anogenital warts with PPD were included. The results were 47 clinical trials and 4 case reports. Most of the research was done in countries with common Mycobacterium tuberculosis infection. The treatment showed good efficacy. Comparative studies showed that the treatment has similar efficacy with other immunotherapies. No significant side effects were reported, with evidence of the safety use on the pregnant population. Conclusion: Based on good efficacy and safety, PPD can be considered an alternative therapy, especially in countries where tuberculosis is frequent.

Increased Expression of Toll-Like Receptor (TLR) 2 and TLR6 on Peripheral Blood Monocytes by Induction of Staphylococcal Enterotoxin B During Exacerbation of Atopic Dermatitis Patients.

Background: Atopic dermatitis (AD) is a chronic and recurrent inflammatory skin disease that can be triggered by various precipitating factors, including colonization by Staphylococcus aureus (S. aureus). The toll-like receptor (TLR), which belongs to the family of pattern recognition receptors (PRR), can recognize components of S. aureus, such as staphylococcal enterotoxin B (SEB). This receptor is known to be expressed on monocytes. However, the understanding of the role of SEB in the pathogenesis of AD through the TLR pathway, especially TLR2 and TLR6, is not widely known. Purpose: To investigate the expression of TLR2 and TLR6 on peripheral blood monocytes induced by SEB during AD exacerbations. Patients and Methods: Twenty AD patients and 20 healthy subjects as a control group were selected. A 5 mL blood sample from each subject was taken for monocyte culture, which was induced by SEB for three days, and the outcomes were assessed by flow cytometry to evaluate TLR2 and TLR6 expression. Results: The expression of TLR2 on peripheral blood monocytes in AD patients was increased compared to healthy controls (p = 0.000), but not for the expression of TLR6 (p = 0.304). In the AD group, TLR2 and TLR6 expression on peripheral blood monocytes after being induced by SEB was significantly increased compared to before induction (p = 0.025 and p = 0.023, respectively), but not in the control group (p = 0.737 and p = 0.100, respectively). Conclusion: There is significantly increased expression of TLR2 and TLR6 on peripheral blood monocytes induced by SEB during exacerbation in AD patients.

Gene Expression of Human Beta-Defensin-3 and Cathelicidin in the Skin of Leprosy Patients, Household Contacts, and Healthy Individuals from Indonesia.

Background: Leprosy, a chronic infectious peripheral neuropathy, is caused by Mycobacterium leprae. This bacterium produces triacylated lipopeptides that can induce the immune system via the Toll-like receptor 2/1 (TLR 2/1) complex. Activation of TLR 2/1 produces proinflammatory cytokines and antimicrobial peptides (AMPs), including human beta-defensin-3 (HBD-3) and cathelicidin. Purpose: To analyze differences in gene expression of HBD-3 and cathelicidin in the skin of leprosy patients, household contacts, and healthy individuals. Patients and Methods: An analytic observational study was conducted at the Outpatient Clinic of Dermatology and Venereology of Dr Mohammad Hoesin General Hospital, Palembang, Indonesia, from January 2021 to June 2022. In each group of 18 subjects, 72 samples were collected, including skin lesion in leprosy patients, normal skin in leprosy patients, household contacts, and healthy individuals. A comparison of HBD-3 and cathelicidin gene expression between the four groups was analyzed using Pearson Chi Square, Kruskal-Wallis, and Mann-Whitney Test. Results: The median value of HBD-3 gene expression on skin lesion in leprosy patients was 260.61 (0.19-3734.10); normal skin in leprosy patients was 1.91 (0.01-151.17); household contacts skin was 7.93 (0.27-121.10); and healthy individuals' skin was 1.00 (1.00-1.00) is highly significant difference (p < 0.0001). The median value of cathelicidin gene expression on skin lesion in leprosy patients was 38.72 (0.28-1852.17); normal skin in leprosy patients was 0.48 (0.01-15.83); household contacts skin was 9.8 (0.04-128.0); and healthy individual skin was 1.00 (1.00-1.00), also highly significant difference (p < 0.0001). Conclusion: Gene expression of HBD-3 and cathelicidin increased in skin lesions of leprosy patients and household contacts.

A Comparison of Cathelicidin Levels in the Skin of Leprosy Patients and Their Household Contacts.

OBJECTIVE: This study aimed to compare cathelicidin levels in the skin of leprae patients and leprae contacts. PATIENTS AND METHODS: This research is an analytic observational study with a cross-sectional approach. Fifty-four research subjects participated in this study. They consisted of leprae patients, household contacts, and healthy individuals. Cathelicidin levels were measured using the ELISA method. Data analysis was carried out with the help of SPSS software, and univariate and bivariate analysis was conducted. RESULTS: Cathelicidin levels in the leprae group (256.8±22.9 pg/ml) were higher than in the contact group (25.9±2.7 pg/ml). Likewise, the contact group had higher cathelicidin levels than healthy controls (1.4±0.1 pg/ml). Statistically, there were differences in cathelicidin levels between groups, P<0.050. CONCLUSION: Cathelicidin levels in leprae patients were higher than those in household contacts.

Lupus Erythematosus Profundus with Multiple Overlying Cutaneous Ulcerations: A Rare Case.

Lupus erythematosus profundus (LEP) is a rare subset of chronic cutaneous lupus erythematosus (CCLE), with a reported incidence of 1-3% in all LE cases. The most common cutaneous clinical presentation includes indurated plaques or subcutaneous nodules with an overlying normal skin. The clinical findings range from skin redness to features of CCLE, such as scaling, follicular plugging, and atrophy. Ulceration is rare and occurs in 28% of all LEP cases. We present a case report of LEP with multiple cutaneous ulcers on the right cheek and scalp accompanied by cicatricial alopecia. No other systemic manifestations were noted. Histopathological examination revealed periadipocyte, perivascular, and perivascular infiltration of lymphocytes, eosinophils, and plasma cells, supporting the diagnosis of LEP. The topical treatments given to the patient were sunscreen, 2% mupirocin cream, and wound dressing with dialkyl carbamoyl chloride (DACC). The patient was also treated systemically with oral corticosteroids and hydroxychloroquine. Clinical improvements were observed in the 3rd month of follow-up, and ulcer healing resulted in atrophic scars and fading erythematous macules. LEP is seldom associated with systemic or discoid lupus erythematosus. This occurs twice as frequently as a distinct entity does. Diagnosis accuracy plays an important role in determining the appropriate wound care, topical, and systemic treatments for LEP patients with multiple overlying cutaneous ulcerations.

The Efficacy of Topical Formulation Containing Ciplukan (Physalis angulata Linn.) in Modulating Interleukin-17 and Interferon Gamma Expression in Mice (Mus musculus) Psoriasis Model.

Background: Interleukin 17 (IL-17) and interferon gamma (IFN-γ) play a role in the pathogenesis of psoriasis vulgaris (PV). Topical corticosteroids are still utilised as first-line therapy for mild to moderate PV. However, long-term use of corticosteroid is associated with various side effects. Physalis angulata Linn. (Ciplukan) possesses anti-inflammatory properties that could serve as a potential alternative topical therapy for PV. Objective: To assess the efficacy of topical ciplukan as an anti-inflammatory agent targeting the expression of IL-17 and IFN-γ. Methods: Psoriasis was induced using imiquimod cream, therefore divided into five groups. Group I, the psoriasis control group, received only imiquimod cream. Groups C1 and C2 received imiquimod cream followed by a mixture of Ciplukan and vaseline in a 1:2 and 1:4 ratio, respectively. Group M, the standard therapy group, received imiquimod cream, followed by mometasone furoate cream. Lastly, group V, the vehicle group, received imiquimod cream followed by vaseline album. Expression of IL-17 and IFN-γ in mice's skin tissue was analysed using reverse transcription polymerase chain reaction (RT-PCR) after seven days of treatment. Results: The mean expression of IL-17 in Group C1 (22.60) was significantly lower (p = 0.012) than in the psoriasis control group (23.60), and there was no significant difference (p = 0.613) in Group M (22.41). The mean expression of IFN-γ in Group C1 (26.97) and Group C2 (27.03) was also significantly lower (p = 0.026 and p = 0.026, respectively) than Group I (28.80), and there was no significant difference (p = 0.180 and p = 0.093, respectively) than Group M (26.03). Conclusion: Expression of IL-17 and IFN-γ in the ciplukan group is lower than in the psoriasis control group, and there is no significant difference compared to the standard therapy group.

A Retrospective Study on the Clinical, Laboratory, and Nutritional Status of Pediatric Epidermolysis Bullosa in a Tertiary Referral Hospital in West Java, Indonesia.

Background: Epidermolysis bullosa (EB) is a genodermatosis disease with bullae and erosions of the skin and mucous membrane that can last for a lifetime and decrease quality of life. Oral and gastrointestinal disorders inhibit the patients' ability to achieve optimal nutrition, making the patients prone to infection, leading to prolonged wound healing, and delayed growth and developmental process. However, there has been no research on the clinical, laboratory, and nutritional status of pediatric EB patients in Indonesia. Purpose: This study aims to describe the clinical, laboratory, and nutritional characteristics of pediatric EB patients treated in Dr. Hasan Sadikin General Hospital Bandung, Indonesia. Patients and Methods: This was a retrospective descriptive study of pediatric EB patient records in Dermatology and Venereology Outpatient of Dr. Hasan Sadikin General Hospital Bandung, Indonesia, from April 2018-March 2020. Results: Study results showed 12 pediatric EB patients consisting of 7 dystrophic EB (DEB) (4 recessive dystrophic EB [RDEB] patients and 3 dominant dystrophic EB [DDEB]), 3 junctional EB (JEB), and 2 EB simplex (EBS). The most extensive EB wounds was found affecting 10-20% of the body surface area with a <10% infected wound area. Pain was found in all patients. The most frequent abnormalities in laboratory examination were anemia and low zinc levels. Severe malnutrition was found in almost half of the patients. Conclusion: RDEB is the most commonly found type of pediatric EB. Wounds on the skin, tooth decay, hand deformity, pain when changing dressings, low zinc levels, and low hemoglobin levels are the clinical features and laboratory findings that contribute to the development of moderate and severe malnutrition in RDEB patients.

Successful treatment of anogenital warts with single dose Bacillus Calmette Guerin vaccine without prior sensitization in tuberculosis endemic country: Two case report.

Anogenital Warts (AGWs) are benign proliferations caused by Human Papillomavirus (HPV) infection on the genital or anal areas. Various therapeutic options are available for the treatment of AGWs but there is no best or ideal therapy, and the recurrence of AGWs is significantly high. A promising new therapy that is currently being evaluated is immunotherapy with the intralesional Bacillus Calmette-Guérin (BCG) vaccine. Two cases of a 23-year-old woman and a 41-year-old man were presented with manifestations of condyloma acuminata type AGWs. The patients were immunocompetent and received single dose intralesional BCG vaccine on the largest lesion. Clinical improvements of AGWs lesions were noted starting on the 14th day after receiving therapy by the disappearance of some lesions with no recurrence and side effects. Intralesional BCG vaccine activates the immune system, treats other AGWs lesions that do not receive an intralesional injection, and also prevents recurrence. Although the intralesional BCG vaccine is effective for treating AGWs, further evaluation is still needed for its recurrence.

Efficacy of LL-37 cream in enhancing healing of diabetic foot ulcer: a randomized double-blind controlled trial.

Wound healing in DFU (diabetic foot ulcer) has prolonged inflammation phase and defective granulation tissue formation. LL-37 has antimicrobial property, induces angiogenesis, and keratinocyte migration and proliferation. This study analyzes the efficacy of LL-37 cream in enhancing wound healing rate and decreasing the levels of IL-1α, TNF-α, and the number of aerobic bacteria colonization in DFU with mild infection. This study was conducted from January 2020 to June 2021 in Jakarta. Subjects were instructed to apply either LL-37 cream or placebo cream twice a week for 4 weeks. Wounds were measured on days 7, 14, 21, and 28 and processed with ImageJ. The levels of LL-37, IL-1α, and TNF-α from wound fluid were measured using ELISA. The number of aerobic bacteria colonization was counted from the isolate grown in culture. The levels of LL-37 in DFU at baseline were equally low in both groups which were 1.07 (0.37-4.96) ng/mg protein in the LL-37 group and 1.11 (0.24-2.09) ng/mg protein in the placebo group. The increase in granulation index was consistently greater in the LL-37 group on days 7, 14, 21, and 28 (p = 0.031, 0.009, 0.006, and 0.037, respectively). The levels of IL-1α and TNF-α increased in both groups on days 14 and 21 (p > 0.05). The decrease in the number of aerobic bacteria colonization was greater in the LL-37 group on days 7, 14 and 21, but greater in the placebo group on day 28 (p > 0.05). In conclusion, LL-37 cream enhanced the healing rate of DFU with mild infection, but did not decrease the levels of IL-1α and TNF-α and the number of aerobic bacteria colonization. This trial is registered at ClinicalTrials.gov, number NCT04098562.

Characteristics of Biofilm-Forming Ability and Antibiotic Resistance of Cutibacterium acnes and Staphylococcus epidermidis from Acne Vulgaris Patients.

Introduction: Acne vulgaris (AV) is a common and chronic disorder of the pilosebaceous unit and has a multifactorial pathology, including activities of Cutibacterium acnes (C. acnes) and Staphylococcus epidermidis (S. epidermidis). Antibiotic resistance has become a major concern in dermatology daily practice, and the ability of biofilm formation by both bacteria is suggested to increase antibiotic resistance in acne. Purpose: Our aim was to analyze the comparison of antibiotic resistance between biofilm-forming (BF) and non-biofilm-forming (NBF) strains of C. acnes and S. epidermidis towards seven antibiotics commonly used for acne. Methods: This is a cross-sectional analytical study involving 60 patients with AV. Samples were obtained from closed comedones on the forehead using the standardized skin surface biopsy (SSSB) method at the Cosmetic Dermatology Clinic Dr. Hasan Sadikin in Bandung, Indonesia. Isolates were cultured and identified before undergoing the biofilm-forming test using the tissue culture plate method. Antibiotic susceptibility testing for each antibiotic was then performed using the disc diffusion method. Results: The incidence of antibiotic resistance to clindamycin in BF and NBF C. acnes isolates was 54.5% (p=1.00), while in BF and NBF S. epidermidis isolates, it was 54.5% and 45.5% respectively (p=0.67). The incidence of antibiotic resistance to erythromycin and azithromycin in BF and NBF C. acnes isolates was 54.5% and 63.6% respectively (p=1.00), whereas for S. epidermidis BF and NBF isolates, it was 54.5% (p=1.00). There was no resistance observed to tetracycline, doxycycline, levofloxacin, and cotrimoxazole in all groups. Conclusion: There were no significant differences in resistance against seven antibiotics between the C. acnes and S. epidermidis in BF and NBF groups. Furthermore, although statistically not significant, some resistances were observed against clindamycin, erythromycin, and azithromycin. Consequently, the use of these three antibiotics should be judiciously regulated.

Multiple Bullous and Ulcers as Cutaneous Manifestations of Wegener's Granulomatosis: A Rare Case Report.

Bullous dermatoses is a heterogeneous group of blistering skin disorders that can either be inherited or acquired. Subepidermal blisters may result in ulceration and scarring following their rupture. Wegener's granulomatosis (WG) is a granulomatous necrotizing vasculitis affecting small- to medium-sized blood vessels. It is associated with anti-neutrophil cytoplasmic antibodies (ANCA) and can be manifested cutaneously as multiple bullous and ulcers. A case of WG was reported in an 18-year-old man presented with multiple skin bullous and ulcers. The patient was diagnosed with WG based on the findings from nasopharyngoscopy examination that revealed crusts in his nasal cavity; necrotizing granulomatous appearance on chest radiograph; hematuria on urinalysis; and positive ANCA blood test. This patient received a combination of methylprednisolone and methotrexate, resulting in improvement within four weeks of therapy. His multiple skin ulcers were treated with a combination of dialkyl carbamoyl chloride, hydrocolloid, and hydrogel dressings. This patient was in complete remission state after six months of treatment, which later followed by a relapse episode that occurred within one year. WG with multiple skin bullous and ulcers can mimic other diseases. Various examinations such as histopathology, direct immunofluorescence, and ANCA blood test may aid in determining the etiology of skin bullous and ulcers.

A Case Report: Clinical Efficacy of Combination Treatment of Dexamethasone and Azathioprine in Recurrent Erythema Multiforme.

Recurrent erythema multiforme (REM) may have frequent episodes over a period of several years and is considered to be a hypersensitivity reaction associated with infection or medication. REM is a mucocutaneous disorder which is characterized by targetoid lesions. Most of the cases are caused by herpes simplex virus infection. Systemic corticosteroid is frequently used to treat REM due to its effects in suppressing the disease. When REM is unresponsive to systemic corticosteroid, steroid-sparing treatment needs to be instituted. We reported a case of REM in a 49-year-old male. There were complaints of burning sensations on the skin lesions, along with swelling on both hands. On physical examination, erythematous macules and targetoid lesions were found on both palms, arms, and legs. During hospitalization, dexamethasone 20 mg was administered in a tapering dose but new skin lesions still appeared. Two days after azathioprine 50 mg twice daily was added to the treatment, skin lesions and swelling on the patient's hands were diminished and the burning sensation disappeared. No side effects of azathioprine were found in this patient and no recurrence until two weeks after hospitalization. This case report demonstrated the efficacy of combined treatment of dexamethasone and azathioprine for REM cases unresponsive to systemic corticosteroid.

The Chemoprotective Role of Vitamin D in Skin Cancer: A Systematic Review.

Introduction: Research in mice showed that vitamin D receptor deficiency was correlated with an increased rate of non-melanoma skin cancer. Therapeutic supplemental vitamin D has also been reported to reduce cell growth in both melanoma and non-melanoma skin cancer. This paper aims to describe the existing research studies that discuss the potential and role of vitamin D in the management of skin cancer. Methods: Articles were searched from three databases (PubMed, ScienceDirect, Scopus) and manual search. 18 articles were included. These were further divided into in vivo and in vitro studies. The literature search was based on the following Patients, Intervention, Control, and Outcome (PICO) criteria: Patients with any types of skin cancer; Vitamin D and their derivates as the intervention; placebo or standard regimen as control, and survival rate or response rate as primary outcome. Results: From the three databases, we obtained 802 studies. Prior to screening of the literature obtained, several studies were excluded. In the eligibility assessment, seven studies were excluded due to their outcomes being not eligible for analysis, and two studies were excluded due to inaccessible full texts. The remaining 18 studies were included. Five studies had a clinical research design (randomized controlled trial or interventional study), which use vitamin D3 as vitamin D derivatives and the results showed that the administration of vitamin D3 reduces the proliferation of skin cancer cells. Similar results were also reported in studies with pre-clinical research designs, either in vivo or in vitro, where six were in vivo studies and nine studies were in vitro studies. Conclusion: Our literature review revealed that that vitamin D derivatives, such as 1,25(OH)2D3 or 20(OH)D3 can effectively reduce the proliferation of skin cancer cells by contributing in the inhibition of cell growth and development, highlighting vitamin D's role as good prognostic factor.

Successful Therapy of Alopecia Universalis Using a Combination of Systemic Methotrexate and Corticosteroids and Topical 5% Minoxidil.

Alopecia areata (AA) is an autoimmune disease-specific to specific organs mediated by T lymphocytes with hair follicles as targets. Severe AA could be in the form of alopecia universalis (AU). AU therapy is relatively difficult and challenging with varying outcomes. Herein, we reported a case of AU in a 19-year-old man with alopecia in the hairy scalp area, eyebrows, eyelashes, moustache, beard, and axillary hair since 2.5 years ago. The patient's severity of alopecia tool (SALT) score was 100%. The patient was given a combination therapy of 15 mg methotrexate per week and 16 mg methylprednisolone per day orally and topical treatment with minoxidil 5%. Observations after nine months of treatment showed an improvement in the decrease in SALT scores to 41%. However, striae were found after 3rd month of therapy. Systemic combination therapy of methotrexate and low-dose corticosteroids and topical minoxidil 5% in this patient gave responsive results. Performed the hematological examination, liver function levels, blood glucose levels, and cortisol during long-term use of methotrexate and corticosteroids are necessary. The combination of systemic methotrexate and corticosteroids, and topical minoxidil showed promising results in AU. Nevertheless, long-term observation is still needed to monitor the side effects of therapy.

Success of Intralesional Purified Protein Derivative Immunotherapy in the Treatment of Anogenital Warts: A Case Report.

Anogenital warts (AGW) are among the most common sexually transmitted infections worldwide. The condition may be persistent, increase in size and number, and have a high recurrence rate. There are many therapeutic options of AGW, but none of them prevented recurrence, only yielded partial responses and have the propensity to cause scars. Immunotherapy by purified protein derivative (PPD) is one of the therapeutic options for AGW, which effectively reduces the number of lesions until complete clearance, with minimal side effects and less recurrence rate. This case report aims to demonstrate the effectiveness, safety, and low recurrence rate of intralesional PPD injection as an alternative therapy for AGW. We reported one case of AGW in an immunocompetent 30-year-old homosexual man who was given 3 doses of 0.2 mL PPD injected intralesionally. As a result, clinical improvement was observed starting from the 18th day, with some of the lesions decreasing in size, and on the 46th day, all of the lesions disappeared. There was no significant side effect. Within two years of follow-up, no recurrence was observed. Intralesional injection of PPD can stimulate the immune response against human papillomavirus (HPV) infection both on the injection site and distant from the injection site. Previous studies have shown promising results of intralesional PPD, with low recurrence in over six-month follow-up and no side effects. Intralesional injection of PPD can be considered as an alternative therapy due to its minimal side effects and its long-term low recurrence rate.
