Elephantiasis Nostras Verrucosa: A Treated Case With Dietary Intervention and Acitretin.

Elephantiasis nostras verrucosa (ENV) is a rare and extreme complication of chronic non-filarial lymphedema. It can lead to severe disfiguration of body parts, especially the lower extremities, and is characterized by non-pitting edema and papulonodules with a verrucose or cobblestone-like appearance. Obesity is a risk factor of ENV. Various treatments have been reported for ENV. A 52-year-old woman presented to our outpatient dermatology clinic with non-pitting edema, cobblestone-like papulonodules, and erythematous plaques on both legs for 2 years. Her medical history included morbid obesity with a body mass index of 44.8 kg/m2, hypertension, and type II diabetes mellitus. Biopsy specimens obtained from skin lesions showed multiple dilated lymph nodes throughout the papillary and reticular dermis. Doppler ultrasonography and lymphoscintigraphy revealed lymph stasis and lymphedema, respectively. Based on clinical, histopathological, and imaging findings, the final diagnosis was ENV. She was initially treated with conservative approaches such as compression stockings and dietary intervention for a month. She went on a low-calorie diet (1350 kcal/day) consisting protein 50.7 g/day, fat 32.5 g/day, and carbohydrate 202.7 g/day, for a month. Owing to the hyperkeratotic lesions, she was given oral acitretin 0.3 mg/kg/day. The dosage was increased to 0.6 mg/kg/day after one month. The lesions were slightly flattened after 2 months of therapy. Acitretin was ceased. Early identification is crucial for preventing morbidity in patients with ENV. Management of ENV is challenging for physicians because of the lack of definitive treatment and poor prognosis. In the management of ENV, it is crucial to treat underlying causes, such as obesity. Acitretin induces loosening and thinning of the hyperkeratotic stratum corneum. Thus, it can result in improvement of cutaneous ENV lesions.

A Rare Case on Capecitabine Induced Acquired Palmoplantar Keratoderma.

Acquired palmoplantar keratoderma (PPK) is a non-hereditary hyperkeratosis of the palms and soles that is caused by various factors, including chemotherapeutic agents. The purpose of this case report is to present a rare case of acquired PPK caused by the chemotherapeutic agent capecitabine. A 54-year-old female complained of painful erythematous plaques on her palms and soles with history of consuming capecitabine. Physical examination revealed scaly erythematous plaques on the palmoplantar surface and knuckle pads on both hands. Histopathological features showed hyperkeratosis, acanthosis, vasodilatation, and perivascular lymphocytic infiltration. Therefore, the patient was diagnosed with acquired PPK due to capecitabine. The dose of capecitabine was reduced and the patient was administered topical corticosteroid and emollient. Improvement of skin lesions was strongly observed after discontinuation of capecitabine. The underlying cause of PPK should be identified to determine the appropriate treatment. Dose reduction or drug discontinuation is the mainstay therapy for patients with acquired PPK caused by chemotherapeutic agents.

Evaluation of Scalp Hydration and pH Values in Hijab-Wearing and Non-Hijab-Wearing Women.

Introduction: Indonesia is the most populous Muslim-majority country, where some women wear hijab covering their scalp and neck. Some hijab-wearing women complain of scalp problems eg, itch, dandruff, and hair loss, which might be related to severe and chronic skin barrier impairment due to occlusion. Excessive water accumulation in the occluded stratum corneum might result in increased permeability, followed by increased skin pH values. This study aimed to evaluate scalp hydration and pH values in hijab-wearing and non-hijab-wearing women. Material and Methods: This was a cross-sectional comparative analytical study using stratified random sampling methods conducted on 63 subjects, who were divided into two groups, consisting of 33 hijab-wearing and 30 non-hijab-wearing women. Both groups underwent physical examination and their medical history recorded. Scalp hydration was measured using a Corneometer (Courage + Khazaka, Koln, Germany), and scalp pH value was measured using a Skin & Scalp pH Tester (Hanna Instruments® HI981037, Rumania). This study was conducted at the Dermatology and Venereology Clinic of Hasan Sadikin General Hospital Bandung. Results: The mean scalp hydration and pH values were 18.34 ± 2.91 AU and 4.93 ± 0.17, respectively, in hijab-wearing women. Meanwhile, the mean scalp hydration and pH values were 17.71 ± 3.35 AU and 4.91 ± 0.16, respectively, in non-hijab-wearing women. The difference of scalp hydration and pH values between the groups was not statistically significant based on the independent t-test, with p-values of 0.430 and 0.597, respectively. Conclusion: Scalp hydration and pH values in hijab-wearing and non-hijab-wearing women did not differ significantly. Hijab-wearing women should not worry about scalp barrier impairment as long as they do not have any history of underlying scalp and skin disorders, and do not wear hijab in wet condition.

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.

A Pilot Study: Composition and Diversity of 16S rRNA Based Skin Bacterial Microbiome in Indonesian Atopic Dermatitis Population.

BACKGROUND: Atopic dermatitis (AD) interferes with quality of life and is influenced by important factors like skin microbiome. The results of the skin microbiome composition and diversity in AD varied in some studies. PURPOSE: This study aims to determine the composition and diversity of the skin microbiome in Indonesian AD patients. PATIENTS AND METHODS: Genomic deoxyribonucleic acid (DNA) preparations were obtained from skin swabs of the cubital fossa of 16 subjects, nine of which were having mild AD, three moderate AD, and four healthy individuals. DNA extraction and sequencing of the 16S ribosomal ribonucleic acid (rRNA) gene using next-generation sequencing and bioinformatics analysis were further performed. RESULTS: Firmicutes (p), Bacilli (c), Bacillales (o), Staphylococcaceae (f), and Staphylococcus (g) were dominant in moderate AD. On the contrary, Proteobacteria (p), Gammaproteobacteria (c), Pseudomonadales (o), Moraxellaceae (f), and Acinetobacter (g) were dominant in mild AD. Staphylococcus aureus was found in the highest number in individuals with moderate AD. Interestingly, Ensifer adhaerens was found in mild AD. Microbial diversity was decreased in moderate AD. CONCLUSION: Metagenomic analysis in this study identified microbes in moderate and mild AD and showed a low diversity of skin microbiomes in moderate AD. Interestingly, this is the first time that the bacteria Ensifer adhaerens was detected on the human skin.

Exfoliative dermatitis due to dermatophytosis.

Exfoliative dermatitis (ED) or erythroderma is defined as diffuse erythema and scaling of the skin involving more than 90% of the total body skin surface, which can be caused by variety of systemic and cutaneous diseases, such as infection, including dermatophytosis. Dermatophytosis is a superficial fungal infection of keratinized tissue caused by dermatophytes. There are only few case reports of ED due to dermatophytosis in literature. A 39-year-old male present with history of diffuse erythematous macules and scales almost on entire body due to dermatophytosis was reported. The diagnosis of dermatophytosis was confirmed by direct microscopic examination, fungal culture, and histopathological examination. Patient was treated with 2% ketoconazole shampoo and two pulses of 1-week of 200 mg itraconazole twice a day for each month. Clinical improvement was showed on the 7th day of observation characterized by decreasing of erythematous macules and scales. Mycological and clinical improvements were obtained on the 29th day of observation. The etiology of ED should be determined in order to give an appropiate treatment.
