Unilateral acne after facial palsy.

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.

Histiocitosis de células de Langerhans: el "camaleón" de la dermatopediatría / Langerhans cell histiocytosis

La Histiocitosis de Células de Langerhans (HCL) es una neoplasia mieloide de las células dendríticas Langerhans (CDL), caracterizada por acúmulos de células dendríticas mieloides CD207+. Corresponden a un espectro de enfermedades, desde sólo cutáneas a variantes multiorgánicas. El objetivo de este reporte es describir el caso clínico de un paciente pediátrico, con diagnóstico de Histiocitosis de Células de Langerhans, enfatizando el algoritmo clínico. Paciente masculino de 1 año y 5 meses, con antecedentes de otorrea persistente, refractaria a tratamiento, de un año de evolución. Consulta en policlínico de dermatología por "dermatitis severa" desde hace 1 año. Al examen físico se constatan lesiones tipo dermatitis seborreica generalizadas en tronco y cuero cabelludo, intertrigo fisurado, pápulas eritemato-costrosas plantares con petequias y pus en conducto auditivo externo bilateral. Presenta Hemoglobina 9,5 mg/dl, Hematocrito31,9%, leucocitos 12.400, linfocitos 33,3%, plaquetas 920.000, VHS 27. Subpoblaciones linfocitarias: CD3: 34,7%, C4: 22,7%, CD8: 9,7%, CD19:47,8%. HTLV negativo, VIH negativo. Acaro-test negativo. Dermatopatología: Denso infiltrado de células linfomonocíticas en dermis papilar, con ensanchamiento de estas y gran epidermotropismo, con abundante citoplasma eosinófilo con núcleos arriñonados, CD1a y langerina positivo. Recomendamos elevar la sospecha diagnóstica ante un cuadro de dermatitis seborreica generalizada que esta fuera del rango etario característico y en casos de dermatitis refractarias, donde a pesar de un adecuado tratamiento médico, el paciente persiste comprometido.

Langerhans Cell Histiocytosis (HCL) is a myeloid neoplasm of Langerhans dendritic cells (CDL), characterized by accumulations of myeloid dendritic cells CD207 +. They correspond to a spectrum of diseases, from cutaneous to multi-organ variants. The objective of this report is to describe the clinical case of a pediatric patient with diagnosis of, emphasizing the clinical algorithm. Male patient,1 year and 5 months old, with a history of refractory persistent otorrhea, consulted because of long term severe dermatitis. Physical examination revealed generalized seborrheic dermatitis lesions on the trunk and scalp, cleft intertrigo, plantar erythematous-crusted papules with petechiae, and pus in the external auditory canal. Laboratory findings showed: Hemoglobin 9.5 mg / dl, Hematocrit: 31.9%, leukocytes: 12,400, lymphocytes 33.3%, platelets: 920,000, HSV 27. Lymphocyte subpopulations: CD3: 34.7%, C4: 22.7%, CD8: 9.7%, CD19: 47.8%. HTLV negative, HIV negative. Scabies Negative. Dermatopathology: Dense infiltrate of lymphomonocytic cells in the papillary dermis with widening of the papilla and large epidermotropism, cells show abundant eosinophilic cytoplasm with "kidney nuclei", CD1a and langerin were positive. We recommend elevating the diagnostic suspicion in the face of a generalized seborrheic dermatitis that is outside the characteristic age range and in cases of refractory dermatitis, where the patient persists compromised.

History of Seborrheic Dermatitis: Conceptual and Clinico-Pathologic Evolution.

Seborrheic dermatitis is an inflammatory and chronic disease with a high incidence and prevalence (1% to 3% in the general population, 3% to 5% in young adults, and 40% to 80% in HIV-positive individuals). Although the condition was first described in 1887, its clinical aspects and clinical forms have still not been well individualized, nor has its etiopathogenesis been fully elucidated. The disease, despite having clinical features similar to dermatitis, does not have the same histopathologic features or the same progressive clinical behavior. This contribution reviews the history of seborrheic dermatitis.

[Dermatologic manifestations associated with HIV/AIDS]. / Manifestaciones dermatológicas asociadas a la infección por VIH/SIDA.

The ongoing human immunodeficiency virus (HIV) infection epidemic coupled with more efficacious and available treatments has led to a larger number of patients living with HIV or AIDS. As a result, skin manifestations related to HIV/AIDS or its therapy have become increasingly more common and are reported to occur in as many as 95% of patients. Herein, we review the most common HIV/AIDS related cutaneous pathologies and classify them into inflammatory, HAART-associated, neoplastic, and infectious manifestations. Cutaneous manifestations should be promptly recognized and treated by physicians and health care personnel in order to provide optimal care.

Manifestações dermatológicas em pacientes infectados pelo HIV: um estudo de prevalência / Dermatological manifestations in HIV-infected patients: a prevalence study

Na infecção pelo HIV, a pele pode ser tanto um indicador precoce de doença quanto de gravidade. Este estudo analisou a frequência e a apresentação clínica de manifestações dermatológicas em pacientes portadores de HIV, destacando as lesões mais encontradas, e correlacionou suas características com o estado imunológico. Foram encontradas 129 lesões mucocutâneas dentre os 57 pacientes portadores de HIV examinados, havendo em média 2,25 lesões por paciente. As dermatoses mais comuns, em ordem decrescente de frequência, foram candidíase oral, onicomicose e dermatite seborreica. As lesões oportunistas mostraram relação significativa com deficiência imunológica, e as afecções de pele mais encontradas mostraram-se bons indicadores do estado imunológico do paciente e da progressão da doença.

In the HIV infection the skin can be either an early indicator of disease and severity. This study examined the frequency and clinical presentation of skin manifestations in patients with HIV, highlighting the most frequent injuries, and correlated their characteristics with the immune status. We found 129 mucocutaneous lesions among 57 patients with HIV, with an average of 2.25 lesions per patient. The most common skin diseases in descending order of frequency were oral candidiasis, onychomycosis and seborrheic dermatitis. Opportunistic lesions showed significant relationship with immune deficiency and the most frequent skin diseases proved to be good indicators of the immune status of the patient and disease progression.

La epidemia del virus de la inmunodeficiencia humana (VIH) sumado al mayor acceso a terapias antiretrovirales (TARV) han llevado a un aumento del número y la sobrevida de pacientes que viven con esta infección crónica. Se estima que hasta 95% de los pacientes con infección por VIH/SIDA presentarán alguna manifestación cutánea, por lo cual, debemos conocerlas. En la presente revisión se estudiarán las manifestaciones cutáneas de la infección por el VIH/SIDA clasificadas como: manifestaciones inflamatorias, manifestaciones asociadas a la TARV, manifestaciones neoplásicas y manifestaciones infecciosas asociadas a infección por VIH/SIDA (bacterianas, virales, fúngicas y parasitarias). Estas manifestaciones deben ser reconocidas por los médicos y el personal de salud a cargo del tratamiento y control de los pacientes con esta patología crónica.

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.

Prediagnostic human T lymphotropic virus type I provirus loads were highest in Jamaican children who developed seborrheic dermatitis and severe anemia.

In a recent clinical analysis of 308 Jamaican children, human T lymphotropic virus type I (HTLV-I) infection was found to be associated with significantly higher incidence rates of seborrheic dermatitis, eczema, and persistent hyperreflexia of the lower limbs and with nonsignificantly increased rates of severe anemia and abnormal lymphocytes. Results of examination of HTLV-I viral markers in the 28 HTLV-I-infected children provided virologic support for the epidemiologic associations of HTLV-I with seborrheic dermatitis and severe anemia in childhood.

A cohort study of health effects of human T-cell lymphotropic virus type I infection in Jamaican children.

OBJECTIVE: Human T-cell lymphotropic virus type I (HTLV-I) infection in childhood is believed to play an important role in risk for adult T-cell leukemia/lymphoma. Although HTLV-I is known to be associated with infective dermatitis in childhood, other HTLV-I-associated morbidity in children has not been well studied. We sought to determine the HTLV-I-associated health effects in Jamaican children. METHODS: We compared incidence rates of several health outcomes in 28 HTLV-I-infected and 280 uninfected children clinically followed from age 6 weeks to a maximum of 10 years. Cox proportional hazards regression analysis was used to analyze these prospectively collected data, adjusting for confounding effects of other variables as necessary. RESULTS: HTLV-I-infected children had significantly higher incidence rates of seborrheic dermatitis (rate ratio [RR] = 4.8, 95% confidence interval [CI] = 1.9-12.5), eczema (RR = 3.1, CI = 1.2-7.9) and persistent hyperreflexia (RR = 3.7, CI = 1.6-8.2). Additionally, HTLV-I infected children had increased rates of severe anemia (RR = 2.5, CI = 0.8-7.9) and abnormal lymphocytes (RR = 2.4, CI = 0.8-7.6) that were of borderline statistical significance. CONCLUSIONS: Our study suggests that HTLV-I-associated skin diseases of childhood may include seborrheic dermatitis and eczema. Additionally, these data suggest that persistent hyperreflexia of the lower limbs may be an early sign of HTLV-I-associated neurologic involvement in children. Expansion and continued clinical observation of this cohort would be valuable.

Etiopatogenia da dermatite seborréica: estado atual / Etiopathogenic of seborrheic dermatitis: actual state

Dermatite seborréica (DS) é dermatose extremamente comum; os aspectos etiopatogênicos ainda säo, no entanto, controversos. Alguns autores acreditam que a Malassezia furfur seja o organismo causal, porém o fungo é isolado da maioria dos indivíduos normais o que contraria essa teoria. Parece que a DS é decorrente de um processo inflamatório que leva à hiperproliferaçäo de queratinócitos e alteraçäo na composiçäo dos lipídios com aumento do colesterol e triglicérides e diminuiçäo de ácidos graxos. Essa alteraçäo aumenta o pH da pele e favorece a supercolonizaçäo pela Malassezia furfur. A populaçäo aumentada de M. furfur, por meio de seus metabólitos, ativa o complemento levando à liberaçäo de fatores quimiotáticos que perpetuam o processo inflamatório. Fatores constitucionais, fisiológicos e ambientais säo relevantes na etiopatogenia da DS, que é considerada multifatorial. O tratamento inclui cuidados gerais, principalmente na DS infantil, exposiçäo a raios ultravioleta e terapêutica tópica e/ou sistêmica.

Pytirosporum ovale en dermatitis seborreica. Estudio en 26 pacientes con SIDA y 21 controles / Pytirosporum ovale in seborrheic dermatitis. a study of 26 patients with AIDS and 21 controls

La dermatitis seborreica (DS) ha sido informada como una entidad frecuente en pacientes con SIDA. En este estudio evaluamos 26 pacientes con SIDA para conocer la prevalencia de DS y su relación con la cuenta de Pytirosporum ovale mediante tinción de Gram y cinta adhesiva transparente, en comparación con controles hospitalizados por enfermedad no relacionadas con el SIDA ni neurológicas. Los resultados fueron semejantes en ambos grupos: la cuenta de P. ovale correlacionó con la forma clínica de la DS; no hubo diferencia entre pacientes con SIDA y controles, ni en los que tomaban ketoconazol. La cuenta de P. ovale fue semejante en las áreas corporales en que se tomaron las muestras. Las técnicas de Gram y cinta adhesiva transparente fueron comparables para cuenta de P. ovale. Conclusiones. En nuestro medio, la DS no es un hallazgo frecuente en población general ni en pacientes con SIDA, y no hay diferencias en el número de P. ovale encontrado en comparación con controles; estos resultados pueden sugerir que la DS, para expresarse, requiere de factores raciales y que se trata de una entidad diferente en la que el P. ovale no es un factor importante en la fisiopatogenia de la enfermedad

Prognosis of infantile seborrheic dermatitis.

Of 191 children who had had infantile seborrheic dermatitis, 88 were reexamined after 10 years. One child had psoriasis, four had atopic dermatitis, and seven had seborrheic dermatitis, which suggests a link with adult seborrheic dermatitis. A familial tendency toward infantile seborrheic dermatitis was noted, as was an increased incidence of allergy within the family.
