In vitro sensitivity of Malassezia furfur isolates from HIV-positive and negative patients to antifungal agents / Sensibilidad in vitro a antifúngicos de aislamientos de Malassezia furfur de pacientes positivos y negativos para HIV

Introduction. Malassezia is a lipophilic and lipid-dependent yeast genus belonging to the skin microbiota of humans and other animals. However, due to dysbiosis processes or other factors in the host, this yeast can cause different pathologies, ranging from skin diseases, such as seborrheic dermatitis, to fungemia. Isolation of Malassezia furfur has been reported in HIV-positive patients with or without skin lesions. Due to its opportunistic nature and its variable resistance to antifungal compounds, it is relevant to know the Malassezia sensitivity profiles. Objective. To determine the sensitivity to different antifungal agents, of clinical isolates of M. furfur obtained from HIV-positive or negative patients, with or without seborrheic dermatitis. Materials and methods. Assessment of isolates sensitivity to itraconazole, voriconazole, fluconazole, and amphotericin B was performed by two techniques: (1) Broth microdilution using Clinical and Laboratory Standards Institute (CLSI) protocol M27-A3 with modifications; and (2) agar tests using Etest®. Results. Isolates obtained from HIV patients showed an increase in the minimum inhibitory concentration of fluconazole, voriconazole, and amphotericin B, compared with those of non-HIV patients. Itraconazole was the antifungal with the lowest minimum inhibitory concentration (MIC) in most isolates. Conclusion. We observed differences in the sensitivity profiles of M. furfur isolates according to the context of the patient. High MIC of antifungals like fluconazole, commonly used for treating pathologies caused by Malassezia, were identified.

Introducción. Malassezia es un género de levaduras lipofílicas que dependen de los lípidos y hacen parte de la microbiota de la piel de humanos y otros animales. No obstante, debido a procesos de disbiosis u otros factores en el huésped, esta levadura puede llegar a causar diferentes enfermedades: desde cutáneas (como dermatitis seborreica) hasta fungemias. Se han reportado aislamientos de Malassezia furfur en pacientes positivos para HIV, con lesiones cutáneas o sin ellas. Por su carácter oportunista y sensibilidad variable a los compuestos antifúngicos, es relevante conocer los perfiles de sensibilidad. Objetivo. Determinar la sensibilidad a diferentes antifúngicos de aislamientos clínicos de M. furfur obtenidos de pacientes positivos o negativos para HIV, con dermatitis seborreica o sin ella. Materiales y métodos. La sensibilidad de los aislamientos a itraconazol, voriconazol, fluconazol y anfotericina B, se determinó mediante dos técnicas: microdilución en caldo según el protocolo M27-A3 del Clinical & Laboratory Standards Institute (CLSI), con modificaciones, y pruebas en agar mediante Etest®. Resultados. Los aislamientos obtenidos de pacientes con HIV mostraron aumento de la concentración inhibitoria mínima a fluconazol, voriconazol y anfotericina B, en comparación con los de pacientes sin HIV. Por otro lado, al evaluar la mayoría de los aislamientos, el itraconazol fue el antifúngico con la menor concentración inhibitoria mínima. Conclusión. Se evidencian diferencias en los perfiles de sensibilidad de los aislamientos de M. furfur, según el contexto del paciente, y elevadas concentraciones inhibitorias mínimas de antifúngicos como el fluconazol, usados comúnmente para el tratamiento de las enfermedades causadas por Malassezia spp.

Histiocitosis de células de Langerhans: reporte de caso y revisión de la literatura / Langerhans cell histiocytosis: Case report and literature review

Resumen La histiocitosis de células de Langerhans comprende un grupo heterogéneo de enfermedades inflamatorias cuyos principales componentes celulares son las células dendríticas y los macrófagos. El infiltrado inflamatorio puede afectar la piel y otros órganos, y el resultado clínico varía de leve a letal, dependiendo del subconjunto de células involucradas y el compromiso multisistémico. La demora en el diagnóstico puede ocurrir debido a su presentación inespecífica y a que los médicos tratantes no suelen sospecharla. Se reporta el caso de una lactante mayor a la cual, a pesar de múltiples consultas con síntomas inespecíficos pero característicos de la enfermedad, solamente se le pudo hacer el diagnóstico gracias a los hallazgos histopatológicos.

Abstract Histiocytosis comprises a heterogeneous group of inflammatory diseases whose main cellular components are dendritic cells and macrophages. The inflammatory infiltrate can affect the skin and other organs and the clinical outcome varies from mild to fatal depending on the involved cell subset and multisystemic compromise. Delay in diagnosis may occur due to its non-specific presentation and to a low suspicion on the part of the clinician. We report the case of an infant who despite multiple consultations with nonspecific but characteristic symptoms of the disease was only finally diagnosed thanks to histopathological findings.

Consensus on the use of oral isotretinoin in dermatology - Brazilian Society of Dermatology

Abstract Background: Isotretinoin is a synthetic retinoid, derived from vitamin A, with multiple mechanisms of action and highly effective in the treatment of acne, despite common adverse events, manageable and dose-dependent. Dose-independent teratogenicity is the most serious. Therefore, off-label prescriptions require strict criteria. Objective: To communicate the experience and recommendation of Brazilian dermatologists on oral use of the drug in dermatology. Methods: Eight experts from five universities were appointed by the Brazilian Society of Dermatology to develop a consensus on indications for this drug. Through the adapted DELPHI methodology, relevant elements were listed and an extensive analysis of the literature was carried out. The consensus was defined with the approval of at least 70% of the experts. Results: With 100% approval from the authors, there was no doubt about the efficacy of oral isotretinoin in the treatment of acne, including as an adjunct in the correction of scars. Common and manageable common adverse events are mucocutaneous in nature. Others, such as growth retardation, abnormal healing, depression, and inflammatory bowel disease have been thoroughly investigated, and there is no evidence of a causal association; they are rare, individual, and should not contraindicate the use of the drug. Regarding unapproved indications, it may represent an option in cases of refractory rosacea, severe seborrheic dermatitis, stabilization of field cancerization with advanced photoaging and, although incipient, frontal fibrosing alopecia. For keratinization disorders, acitretin performs better. In the opinion of the authors, indications for purely esthetic purposes or oil control are not recommended, particularly for women of childbearing age. Conclusions: Approved and non-approved indications, efficacy and adverse effects of oral isotretinoin in dermatology were presented and critically evaluated.

Eficácia de uma nova geração de xampus no controle da dermatite seborreica do couro cabeludo / Efficacy of a new generation of shampoos in controlling seborrheic dermatitis of the scalp

Introdução: A dermatite seborreica é uma doença inflamatória crônica sobre áreas com maior concentração de glândulas sebáceas, com participação de fungos do gênero Malassezia sp. Objetivo: Avaliar a eficácia do tratamento da dermatite seborreica moderada a intensa com o uso de duas formulações de xampu em monoterapia. Métodos: Pacientes portadores de dermatite seborreica de couro cabeludo moderada à intensa, com cabelos processados quimicamente ou não, foram agrupados de acordo com o grau da afecção e usaram uma das duas versões de xampus em monoterapia, por quatro semanas. Também foi avaliada a ocorrência de recidivas após a suspensão do tratamento. Resultados: Houve redução significativa (p<0,05) da oleosidade desde a primeira aplicação. Os demais sinais (eritema e descamação) apresentaram melhora significativa para ambos os tratamentos. Também foi relatada uma melhora significativa do prurido, eritema e descamação pelos participantes. O efeito sobre os fios foi considerado positivo com ambos os tratamentos. Após uma semana da suspensão, o índice de recidivas foi considerado não significativo (p<0,05). Conclusões: As duas versões de xampus foram capazes de promover um controle efetivo da dermatite seborreica moderada à intensa. Essas formulações demonstraram também não agredirem os fios, mesmo quando processados, fato considerado fundamental para a adesão ao tratamento.

Introduction: Seborrheic dermatitis is a chronic inflammatory disease in areas with a higher concentration of sebaceous glands and the participation of the fungi of the genus Malassezia sp. Objective: To assess the effectiveness of treating moderate to severe seborrheic dermatitis using two shampoo formulations in monotherapy. Methods: Patients with moderate to severe seborrheic dermatitis of the scalp, with or without chemically processed hair, were grouped according to the degree of affection and used one of two versions of shampoo monotherapy for four weeks. Relapse after treatment cessation was also evaluated. Results: There was a significant reduction (p <0.05) of oiliness since the first application. The other signs (erythema and peeling) showed significant improvement for both treatments. Participants also reported a considerable improvement in pruritus, erythema, and peeling. The effect on the hair strands was considered positive with both procedures. After one week of suspension, the relapse rate was considered non-significant (p <0.05). Conclusions: Both versions of shampoos were able to promote effective control of moderate to severe seborrheic dermatitis. These formulations also demonstrated not to harm the hair strands, even when chemically processed, a fundamental fact to treatment adherence.

Demodex folliculorum infestations in common facial dermatoses: acne vulgaris, rosacea, seborrheic dermatitis

Abstract Background: Demodex mites are found on the skin of many healthy individuals. Demodex mites in high densities are considered to play a pathogenic role. Objective: To investigate the association between Demodex infestation and the three most common facial dermatoses: acne vulgaris, rosacea and seborrheic dermatitis. Methods: This prospective, observational case-control study included 127 patients (43 with acne vulgaris, 43 with rosacea and 41 with seborrheic dermatitis) and 77 healthy controls. The presence of demodicosis was evaluated by standardized skin surface biopsy in both the patient and control groups. Results: In terms of gender and age, no significant difference was found between the patients and controls (p > 0.05). Demodex infestation rates were significantly higher in patients than in controls (p = 0.001). Demodex infestation rates were significantly higher in the rosacea group than acne vulgaris and seborrheic dermatitis groups and controls (p = 0.001; p = 0.024; p = 0.001, respectively). Demodex infestation was found to be significantly higher in the acne vulgaris and seborrheic dermatitis groups than in controls (p = 0.001 and p = 0.001, respectively). No difference was observed between the acne vulgaris and seborrheic dermatitis groups in terms of demodicosis (p = 0.294). Study limitations: Small sample size is a limitation of the study. The lack of an objective scoring system in the diagnosis of Demodex infestation is another limitation. Conclusion: The findings of the present study emphasize that acne vulgaris, rosacea and seborrheic dermatitis are significantly associated with Demodex infestation. Standardized skin surface biopsy is a practical tool in the determination of Demodex infestation.

Isolation of Malassezia spp. in HIV-positive patients with and without seborrheic dermatitis

Abstract Background Malassezia, a skin saprophyte, is frequently isolated from patients with seborrheic dermatitis, which is one of the most common dermatoses in HIV-infected patients. Its role in pathophysiology has not been defined. Objective To determine whether patients living with HIV and seborrheic dermatitis have more Malassezia than those without seborrheic dermatitis. Method This is an descriptive, observational, prospective cross-sectional study to which all adult patients living with HIV that attend the infectious disease outpatient clinic at the Dr. Manuel Gea González General Hospital were invited. Patients presenting with scale and erythema were included in Group 1, while patients without erythema were included in Group 2. Samples were taken from all patients for smear and culture. Results Thirty patients were included in each group. All patients with seborrheic dermatitis had a positive smear, with varying amounts of yeasts. In the control group, 36.7% of patients had a negative smear. The results are statistically significant, as well as the number of colonies in the cultures.Study limitations The study used a small sample size and the subspecies were not identified. Conclusions Patients with clinical manifestations of seborrheic dermatitis have larger amounts of Malassezia. Further studies need to be performed to analyze if the greater amount is related to imbalances in the microbiota of the skin.

Second-to-fourth digit ratio and seborrheic dermatitis in males: a cross-sectional study*

Abstract: Background: Seborrheic dermatitis is a common disease characterized by the erythematous plaques with oily-yellow desquamation. Increased sebaceous gland activity by androgenic hormones has played a role in the etiology of the disease. The second-to-fourth digit (2D:4D) ratio is thought to be a marker of prenatal androgen exposure. Objectives: To investigate the association between 2D:4D ratios and seborrheic dermatitis in a male population. Methods: Healthy male controls and patients with seborrheic dermatitis were included in this study. One hundred seborrheic dermatitis patients and 120 healthy controls, aged 17-59, were enrolled. A digital Vernier caliper was used to measure the finger lengths. Seborrheic dermatitis severity was assessed using the Seborrheic Dermatitis Area and Severity Index (SDASI). Results: The 2D:4D ratios of the patients (x = 0.977) were significantly lower than those of the controls (x = 1.050) for right hands (t = 6.948; p = 0.000; > 0.05). No similar relationship was found between the 2D:4D ratio for left hands (t = 0.901; p = 0.368; > 0.05). Seborrheic dermatitis severity was negatively correlated with 2D:4D ratios of right hands (r = -0.391; p = 0.000-0.05). Study limitations: One of the main limitations of this study was the small sample, which got a head of us from acquiring certain findings about the 2D:4D ratio and seborrheic dermatitis. The other limitation is that the patient selection did not reflect the general population, as a single clinic was studied. Conclusion: To the authors' knowledge, this is the first study examining the relationship between 2D:4D ratios and seborrheic dermatitis. The result of this study may indicate a line of investigation and can support the theory of prenatal androgen exposure.

Unilateral acne after facial palsy

Abstract: We describe a case of unilateral acne which appeared after an episode of facial nerve palsy. An 18-year-old female patient presented with papules and pustules predominantly located on the side where the facial paralysis occurred. The patient suffered right facial paralysis, which was treated with prednisone and kinesiotherapy with massages, electrostimulation, and infrared light. Two weeks later, acne lesions appeared in the area affected by the paralysis. As suggested in other cases of paralysis, including cases of Parkinson's disease and spinal cord injury, an increased sebum excretion rate and the immobility of the affected area are most likely what caused the unilateral acne lesions.

Miasis cutánea por Cochliomyia hominivorax asociada a dermatitis seborreica: case report / Cutaneous myiasis due to Cochliomyia hominivorax associated with seborrheic dermatitis

Myiasis is an infestation of tissues and organs of humans and animals by Diptera larvae (flies, horseflies, mosquitoes). They are located at different body sites, and classified clinically as cutaneous, visceral and cavitary. We report a 26-year-old woman with a history of seborrheic dermatitis and recent trip to Brazil. She presented with a seven days history of suppurating wounds in the parieto-occipital area of the scalp. At physical examination we found three ulcers of approximately 1.5 cm each, with multiple mobile larvae inside. The obtained larvae were analyzed, identifying Cochliomyia hominivorax larvae at L2 and L3 stages. The patient was managed successfully with oral antimicrobials and local cleansing. The screwworm Cochliomyia hominivorax in our country is rare. Known risk factors are wounds, poor personal hygiene, extreme ages, psychiatric disorders, presence of specific dermatosis such as psoriasis and seborrheic dermatitis, among others.

Pharmacologic treatment of seborrheic dermatitis

Seborrheic dermatitis is a chronic, recurrent papulosquamous skin disorder characterized by flaking of the skin, erythema, pruritus, and oily skin. It is a common dermatosis, with a prevalence of approximately 1% to 3% of the general population in the United States. The incidence of this skin disease has a bimodal distribution, with peaks noted in newborns and in adults between 30 and 60 years of age. In adults, it predominantly occurs over areas of the body with a high concentration of sebaceous glands. The etiology of this disease is thought to be an inflammatory response of the body to Malassezia yeasts. It is also related to abnormal sebum secretion, as well as a heightened immune response of the host. Based on the characteristic features of this inflammatory skin disease, the mainstays of treatment for seborrheic dermatitis are antifungals, corticosteroids, and immunomodulatory agents. The primary goal of therapy for seborrheic dermatitis is to manage acute symptoms, including pruritus, erythema, and scaling. Maintenance treatment is directed toward preventing the recurrence of acute exacerbations. Patients should be informed that seborrheic dermatitis is a chronic condition, with a tendency to recur despite proper treatment. Clinicians should offer suggestions about lifestyle modifications to avoid triggers and choose proper treatment options that ensure the patient's safety.

Pityriasis amiantacea: clinical-dermatoscopic features and microscopy of hair tufts / Pitiríase amiantácea: aspectos clínicos e dermatoscópicos e microscopia dos tufos capilares

Pityriasis Amiantacea, also known as pseudotinea amiantacea, is a clinical syndrome which affects the scalp, having a reaction pattern reported to occur in several inflammatory dermatoses. The authors seek to establish the correlation between its clinical, dermoscopic and light microscopy features through the analysis of scale- encrusted hair tufts submitted to histological processing.

A pitiríase amiantácea, também chamada de pseudotínea amiantácea, é compreendida como uma síndrome clínica que acomete o couro cabeludo. Representa um padrão de reação a diversas dermatoses inflamatórias. Os autores procuram estabelecer a correlação entre características clínicas, dermatoscópicas e de microscopia ótica, através da análise do tufo de cabelos agregados pelas escamocrostas, submetido a processamento histológico.

Dermatite seborreica / Seborrheic dermatitis

A dermatite seborreica é uma doença eritêmato-escamativa de caráter crônico-recidivante que acomete entre 1 e 3 por cento da população geral dos Estados Unidos. Possui dois picos de incidência - o primeiro, durante os três primeiros meses de vida, e o segundo, a partir da puberdade, atingindo seu ápice entre os 40 e 60 anos de idade. Os indivíduos HIV positivos têm maior prevalência da doença, que apresenta maior intensidade e tendência à refratariedade ao tratamento. Doenças neurológicas e outras doenças crônicas também estão associadas ao desenvolvimento da dermatite seborreica. Como mecanismo fisiopatogênico, reconhece-se que o fungo Malassezia sp., presente na pele de indivíduos suscetíveis, leve a uma irritação não-imunogênica a partir da produção de metabólitos à base de ácidos graxos insaturados deixados na superfície cutânea. Este artigo faz uma revisão da literatura sobre dermatite seborreica, com ênfase nos aspectos imunogenéticos, formas clínicas e tratamento.

Seborrheic dermatitis is a chronic relapsing erythematous scaly skin disease, the prevalence of which is around 1 to 3 percent of the general population in the United States. It has two incidence peaks, the first in the first three months of life and the second beginning at puberty and reaching its apex at 40 to 60 years of age. The prevalence of seborrheic dermatitis is higher in HIV-positive individuals and the condition tends to be more intense and refractory to treatment in these patients. Neurological disorders and other chronic diseases are also associated with the onset of seborrheic dermatitis. The currently accepted theory on the pathogenesis of this disease advocates that yeast of Malassezia spp., present on the skin surface of susceptible individuals, leads to a non-immunogenic irritation due to the production of unsaturated fatty acids deposited on the skin surface. This article provides a review of the literature on seborrheic dermatitis, focusing on immunogenetics, the clinical forms of the disease and its treatment.

Prevalencia de infección por VIH en pacientes con patología dermatológica en un centro de referencia nacional 2005-2006 / HIV infection prevalence in patients having cutaneous pathology in a national reference center (2005-2006)

Objetivo Estimar la prevalencia de infección por VIH en pacientes con patología cutánea en un centro de referencia nacional en Colombia. Métodos Se realizó un estudio de corte transversal, en pacientes dermópatas mayores de 18 años, sin diagnóstico previo de infección por VIH. Se calculó un tamaño muestral de 1 537 pacientes. Se definió como caso confirmado un paciente con pruebas positivas de Elisa y Western Blott. La prevalencia se calculó como el número de casos confirmados sobre el total de la población. Se evaluaron asociaciones mediante el estimador de razón de prevalencias. Resultados Ingresaron al estudio 1 649 pacientes. En total 20 sujetos fueron definidos como caso confirmado, para un prevalencia del 1,21 por ciento. Los moluscos contagiosos y la dermatitis seborreica fueron las enfermedades con la más alta prevalencia de infección por VIH no diagnosticada previamente (3,91 por ciento y 2,05 por ciento respectivamente). La razón de prevalencias de molusco contagioso e infección por VIH fue de 3,96 (p: 0,01562). Conclusiones Los pacientes mayores de 18 años con diagnóstico de moluscos contagioso tienen casi 4 veces el riesgo de los otros pacientes dermópatas de tener infección por VIH.

Objective Determining the prevalence of HIV infection in patients suffering from cutaneous disease in a national reference center in Colombia. Methods This was a cross-sectional study of patients aged 18 or older, having cutaneous pathology and no previous HIV diagnosis. The calculated sample size was 1,537 patients. A confirmed case was defined as being that of a patient having positive results in the ELISA and Western blot tests. Prevalence was the number of confirmed cases divided by the total population. The associations were measured by using prevalence ratio. Results 1,649 patients were enrolled in the study. Our center’s prevalence was 1.21 percent (20 cases). Molluscum contagiosum and seborrheic dermatitis were the diseases having the highest prevalence of HIV infection which had not been previously diagnosed (3.91 percent and 2.05 percent, respectively). Molluscum contagiosum and HIV infection prevalence ratio was 3.96 (p: 0.01562). Conclusions The risk of HIV infection in patients aged 18 or older suffering from Molluscum contagiosum was nearly 4 times higher than the risk in patients having other cutaneous pathologies.

Treatment of Facial Seborrheic Dermatitis with Pimecrolimus Cream 1%: An Open-Label Clinical Study in Korean Patients

Pimecrolimus cream 1% has shown to be effective in patients with a variety of inflammatory cutaneous disorders. And it might be a useful modality in the treatment of seborrheic dermatitis. This prospective study was aimed at assessing the efficacy and tolerability of pimecrolimus cream 1% in the treatment of facial seborrheic dermatitis. Twenty patients were instructed to apply pimecrolimus cream 1% for 4 consecutive weeks. Assessment of the disease severity was performed at baseline and at week 1, 2, and 4. Clinical assessments of erythema, scaling, and pruritus were measured using a 4-point scale (0-3). Global assessments of the disease severity by patients and investigators were performed at each visit. Mean clinical scores of erythema, scaling, and pruritus significantly improved by 87.4%, 91.9%, and 91.5% respectively at week 4 (p<0.001). Improvements in the global assessment of disease severity determined by patients and investigators also showed excellent results. No specific adverse events other than transient burning and tingling sensations were noted. The relapse of facial seborrheic dermatitis was mostly observed between 3 to 8 weeks after the discontinuation of pimecrolimus. We suggest that the topical application of pimecrolimus cream 1% can be an effective and safe alternative for treatment of facial seborrheic dermatitis.
