Abstract

Introduction: Leprosy and Human Immunodeficiency Virus (HIV) infections still count as major health issues worldwide. Starting with the HIV pandemic back in the eighties, leprosy was feared to re-emerge as the HIV cases arose. Co-infections between leprosy and HIV were worried to cause an increase in leprosy cases, with worse clinical manifestation, predominantly toward the lepromatous spectrum, decrease in therapy response, and prolonged therapy period. Unlike its interaction with tuberculosis, HIV infection was turned out to not increasing nor deteriorating the manifestation of leprosy infection. All clinical spectrum of leprosy was found in HIV infection patients without predomination of lepromatous type. Responses to leprosy Multi-Drug Therapy (MDT) regimen were also found similar between leprosy patients with or without HIV.Conclusion: It is recommended to treat co-infective patients both with leprosy MDT and antiretroviral therapy. Manifestation of leprosy as a part of immune reconstitution syndrome need more attention and investigation.Keywords: HIV infection, leprosy, interaction

Abstract

Background: Melasma is an acquired chronic hyperpigmentation mostly affecting women. The pathogenesis of melasma is uncertain but it predominant related to ultraviolet (UV) exposure. Due to chronic and relapsing nature, melasma is challenging to treat. The current available treatment often has undesirable side effects and suboptimal results. The principal of treatment includes protect from UV radiation, inhibit melanin synthesize and increase pathway to remove melanin. Objectives: To define available treatments for melasma and determine advantages and disadvantages including topical, oral and procedural. Method: Medline, Cochrane library and PubMed database were searched for articles from January 2011 to June 2020. Only RCTs, comparative, prospective, retrospective and systematic reviews focusing on melasma treatments were extracted, analyzed and discussed. Results: We found 197 studies that met the inclusion and exclusion criteria with 2314 participants included in this review. The treatments included topical, oral and procedural. In several studies, hydroquinone alone or combination remains the most effective treatment for melasma. Oral and topical tranexamic acid have been found to be a useful adjuvant treatment in refractory melasma with minimal adverse effects. Procedural treatment such as chemical peels, laser and light-based therapies, and microneedling have a mixed and unpredictable result. Overall, the side effects tend to be mild and affect few of the subject.Conclusions: The current state of the evidence suggests that some treatments with multiple modalities have their respective advantages and disadvantages. The choice of treatment modality must be adjusted according to the type of melasma such as its severity, extent and location. A better understanding of melasma through the further research may improve the therapy options with the least adverse effects.

Abstract

Introduction: Harlequin ichthyosis is a genetic skin disease due to mutations in the ABCA12 gene inherited in an autosomal recessive manner. It is a severe form of ichthyosis characterized by a distinct clinical appearance of a thick stratum corneum. Harlequin ichthyosis is rarely found, and patients generally die a few days after birth.Case description: We reported a baby girl aged one day with thick and cracked skin since birth. Physical examination revealed eclabium, ectropion, microtia, hyperflexion of the arms and legs, and hypoplasia of the fingers and toes. Dermatological examination showed thick yellowish-white scales separated by deep and erythematous fissures. The patient was placed in an incubator and was given supportive care, including nutrition and fluid through an orogastric tube, oleum olivarum as a moisturizer, gentamicin cream 0.1%, and gentamicin eye ointment 0.3%. The patient died after 21 days of treatment.Conclusion: Harlequin ichthyosis has a poor prognosis and a high mortality rate due to impaired skin barrier functions that lead to dehydration, impaired thermoregulation, respiratory problems, and infections. Management of harlequin ichthyosis needs a multidisciplinary team and supportive care, consisting of fluid, electrolyte, and nutrition management, maintaining skin hydration, eye care, and preventing respiratory failure or sepsis.  Pendahuluan: Harlequin ichthyosis adalah penyakit kulit genetik yang diturunkan secara resesif autosomal dan merupakan bentuk berat dari iktiosis akibat adanya mutasi pada gen ABCA12. Penyakit ini ditandai dengan adanya gambaran klinis yang khas berupa penebalan stratum korneum. Harlequin ichthyosis jarang ditemukan dan umumnya pasien meninggal beberapa hari setelah kelahiran.Kasus: Dilaporkan seorang bayi perempuan berumur 1 hari dengan keluhan kulit tebal dan pecah-pecah sejak lahir. Pada pemeriksaan fisik ditemukan eklabium, ektropion, mikrotia, hiperfleksi lengan dan kaki, serta hipoplasia jari-jari tangan dan kaki. Berdasarkan pemeriksaan status dermatologikus didapatkan skuama tebal berwarna putih kekuningan yang dipisahkan fisura. Pasien diberikan perawatan suportif berupa perawatan dalam inkubator, pemberian nutrisi melalui OGT, pelembab topikal oleum olivarum, antibiotik topikal gentamisin krim 0,1 %, dan salep mata gentamisin 0,3%.  Pasien meninggal setelah perawatan selama 21 hari. Simpulan: Harlequin ichthyosis memiliki prognosis yang buruk dan angka kematian yang tinggi akibat gangguan dari barier kulit yang menyebabkan dehidrasi, gangguan termoregulasi, gangguan nafas dan infeksi. Penatalaksanaan pasien harlequin ichthyosis adalah multidisiplin dan bersifat suportif, terdiri atas manajemen cairan dan elektrolit, perawatan secara intensif dalam inkubator, pemberian nutrisi, menjaga hidrasi kulit, perawatan mata, dan pencegahan terjadinya gangguan napas, atau sepsis.

Abstract

Background: Chromoblastomycosis is a chronic profound fungal infection caused by dematiaceous from the surrounding environment. Trauma was the site of fungal implantation. The prevalence is mainly in agriculture workers. The clinical picture varies. Diagnosis is made when muriform cells are found. Early diagnosis is very important because it affects the prognosis. Case Description: A woman, 24 years old, Balinese, went to The Skin and Genital Polyclinic of Sanglah General Hospital with the main complaint of boils in the area below the left knee six months ago. It starts from red papules and then becomes a painless lump.  The lump breaks and contains yellowish pus. Patients have a history of gardening. Physical examination within normal limits. Dermatological status on left cruris, there are solitary erythema nodules, firm borders, round shape, a diameter of 2.5 cm, smooth and shiny surface, and fluctuations containing yellowish pus. From sabouraud dextrose agar culture (SDA) obtained the growth of Cladophialophora carrionii. The diagnosis was chromoblastomycosis. Patients were given a pulse dose of itraconazole 400 mg every 24 hours intraorally. There was a clinical improvement. Conclusion: There have been reported cases of chromoblastomycosis that were initially suspected to be furuncle in a 24-year-old woman. Diagnosis is made based on anamnesis, physical examination, and laboratory examination. Patients were given a pulse dose of itraconazole. There was a clinical improvement. The prognosis is dubius ad bonam. Extended observations still need to monitor the clinical and mycological healing, medication side effects and complications of the disease.   Latar belakang: Kromoblastomikosis adalah infeksi jamur profunda kronik yang disebabkan oleh dematiaceous yang berasal dari lingkungan sekitar. Penyakit ini biasanya diawali oleh trauma sebagai situs implantasi jamur. Prevalensi penyakit ini terutama pada individu yang bekerja di bidang agrikultural. Gambaran klinis kromoblastomikosis bervariasi. Penegakan diagnosis bila ditemukan sel muriform pada jaringan. Diagnosis dini pada lesi awal sangat penting karena mempengaruhi prognosis penyakit. Deskripsi kasus: Seorang perempuan, 24 tahun, suku Bali, berobat ke Poliklinik Kulit dan Kelamin RSUP Sanglah Denpasar dengan keluhan utama bisul pada area bawah lutut kiri sejak 6 bulan yang lalu. Awalnya berupa bintil kemerahan lalu menjadi benjolan yang tidak nyeri. Benjolan pecah dan mengeluarkan nanah. Pasien memiliki hobi berkebun. Pemeriksaan fisik dalam batas normal. Status dermatologi pada regio kruris sinistra terdapat nodul eritema soliter, batas tegas, bentuk bulat, diameter 2,5 cm, permukaan halus dan mengkilap, tampak fluktuasi berupa pus kekuningan. Pemeriksaan kultur sabouraud dextrose agar (SDA) didapatkan pertumbuhan Cladophialophora carrionii. Diagnosis kerja adalah kromoblastomikosis. Pasien diterapi dengan itrakonazol 400 mg setiap 24 jam intraoral dosis denyut dan terdapat perbaikan klinis pada lesi.   Simpulan: Telah dilaporkan kasus kromoblastomikosis yang awalnya diduga furunkel pada seorang perempuan usia 24 tahun. Diagnosis ditegakkan berdasarkan anamnesis, pemeriksaan fisik, dan pemeriksaan penunjang. Pasien diberikan terapi itrakonazol dosis denyut dan tampak perbaikan klinis yang signifikan pada lesi.

Abstract

Introduction: Melasma is an acquired pigmentation disorder characterized by symmetrical hyperpigmented patches, most commonly seen on the face. Melasma and iron deficiency are most common in women of reproductive age. Iron deficiency causes a decrease in ferritin levels, which are iron stores in the body. The mechanism of iron deficiency causing melasma is thought to be due to cell hypoxia in the tissue involving mediators that increase melanogenesis. This study aims to prove that the mean ferritin level is lower in melasma than without melasma and that low ferritin levels are a risk factor for melasma in women. Methods: A case-control research included 28 participants with melasma and 28 without melasma who visited the dermatovenereology department of Prof. Dr. I.G.N.G Ngoerah Hospital, medical cosmetic division, in May-July 2022. The two groups will compare ferritin mean and ferritin risk factor analysis on the incidence of melasma. Data were tabulated and analyzed using SPSS 26. Results: The mean age in the melasma group was 40.64±3.39 years old, and the group without melasma was 37.64±3.50 years old (p=0.75). Of the 28 melasma subjects, there were more subjects with low ferritin levels (60.7%) than the group without melasma (32.1%). From the results of the Mann-Whitney test, the mean ferritin level in the melasma group (36.32±31.05) was significantly lower than in the non-melasma group (58.26±5.39); p=0.006. From the results of the Chi-Square test, it was found that low ferritin levels had a risk of 3.2 times the occurrence of melasma [OR (95% CI) = 3.2 (1.098-9.776), p=0.032]. Conclusion: The mean ferritin level in women with melasma is lower than in women without melasma, and low ferritin levels are a risk factor for melasma.   Latar Belakang: Melasma merupakan kelainan pigmentasi didapat yang ditandai dengan adanya bercak hiperpigmentasi simetris, paling sering terlihat pada wajah. Melasma dan defisiensi besi paling sering dijumpai pada wanita usia reproduktif. Defisiensi besi menyebabkan turunnya kadar feritin yang merupakan cadangan besi dalam tubuh. Mekanisme defisiensi zat besi menyebabkan melasma diduga akibat hipoksia sel di dalam jaringan melibatkan mediator yang meningkatkan melanogenesis. Studi ini bertujuan untuk membuktikan rerata kadar feritin lebih rendah pada melasma dibandingkan tanpa melasma serta membuktikan kadar feritin yang rendah merupakan faktor risiko melasma pada wanita. Metode: Studi case-control yang melibatkan 28 subjek dengan melasma dan 28 subjek tanpa melasma yang berobat ke poliklinik kulit dan kelamin RSUP Prof. Dr. I.G.N.G Ngoerah divisi kosmetik medik periode Mei-Juli 2022. Kedua kelompok akan dibandingkan rerata feritin dan analisis faktor risiko feritin terhadap kejadian melasma. Data ditabulasi dan dianalisis dengan menggunakan SPSS 26. Hasil: Rerata usia pada kelompok melasma 40.64±3,39 tahun dan kelompok tanpa melasma 37,64±3,50 tahun (p=0,75). Dari 28 subjek melasma, didapatkan lebih banyak subjek dengan kadar feritin rendah (60,7%) dibandingkan kelompok tanpa melasma (32,1%). Dari hasil uji Mann-Whitney didapatkan rerata kadar feritin pada kelompok melasma (36,32±31,05) lebih rendah secara signifikan dibandingkan pada kelompok bukan melasma (58,26±5,39); p=0,006. Dari hasil uji Chi-Square didapatkan kadar feritin yang rendah memiliki risiko sebesar 3,2 kali terjadinya melasma [OR (IK 95%) =3,2 (1,098-9,776), p=0,032]. Simpulan: rerata kadar feritin pada wanita dengan melasma lebih rendah dibandingkan wanita tanpa melasma dan kadar feritin yang rendah merupakan faktor risiko melasma.
