ABSTRACT

Introdução: O microagulhamento é uma técnica utilizada para o tratamento de cicatrizes e apresenta cada vez mais destaque na Dermatologia. Nesse contexto, em associação com o microagulhamento, drogas e ativos podem ser administrados por meio da técnica conhecida como drug delivery. Destaca-se o uso da vitamina C, por sua já comprovada ação antioxidante. Outro exemplo é a andiroba (Carapa guianensis Aubl.), por suas propriedades anti-inflamatória, analgésica, antisséptica e cicatrizante. Objetivo: Avaliar os efeitos da andiroba associada ao microagulhamento. Métodos: Foram utilizados 31 ratos machos distribuídos em cinco grupos: GPi (piloto), com três animais; GM (microagulhamento); GMA (microagulhamento + andiroba); GMV (microagulhamento + vitamina C); e GOM (microagulhamento + óleo mineral), com sete animais em cada grupo. Os animais foram submetidos à técnica do microagulhamento no D0 (dia 0) e à aplicação da substância do seu respectivo grupo, na pele, pela manhã, durante sete dias. Resultados: Houve diferença significativa entre a intensidade de proliferação fibroblástica e a vascularização observadas no tecido dos animais dos grupos GM e GMV. Já a intensidade de fibras colágenas foi superior nos animais do grupo GMV. Conclusões: O óleo de andiroba como drug delivery obteve resultados inferiores à vitamina C.


Introduction: Microneedling is a technique used to treat scars with increasing popularity in dermatology. In this context, associated to micro-needling, drugs and active substances can be administered through the technique known as drug delivery. We highlight the use of vitamin C, due to its known antioxidant properties. Another example is Carapa guianensis Aubl., due to its anti-inflammatory, analgesic, antiseptic and healing properties. Objective: To evaluate the effects of Carapa guyanensis associated to microneedling. Methods: Thirty-one male mice, distributed into five groups, were used: GPi (pilot), with three animals; GM (micro-needling); GMA (micro-needling + Carapa guyanensis); GMV (microneedling + vitamin C); and GOM (microneedling + mineral oil), with seven animals in each group. The animals were submitted to the microneedling technique on D0 (day 0) and to the application of the substance of its respective group in the skin, in the morning for seven days. Results: There was a significant difference between the expression of fibroblast proliferation and vascularization observed in the tissue of animals in groups GM and GMV. The expression of collagen fibers was superior in animals in the GMV group. Conclusions: Carapa guyanensis oil had inferior results as drug delivery when compared to vitamin C.

ABSTRACT

Abstract: Cutaneous metastases from internal malignant neoplasms are a rare event and a late clinical finding that is associated with disseminated disease and a poor prognosis. Skin metastases from colon tumors occur in only 4% of cases of metastatic colorectal cancer. They are most often located on the abdominal skin. We report a case of 54-year-old male patient with a cutaneous metastatic focus on the lower abdomen as the initial presenting symptom of an underlying colon cancer.

ABSTRACT

Abstract: Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient's history of pencil tip injury and histological examination findings.

ABSTRACT

Clear cell acanthoma or Degos' acanthoma is a distinct disease concerning its clinical, histopathological, and immunohistochemical features. Its pathologic nature - whether neoplastic or reactive - is still under dispute among researchers. The disease shows a chronic course and often presents with a single papulonodular lesion on the lower limbs of adults. However, cases with multiple lesions, sometimes occurring in an eruptive fashion, and with clear variation in the size and shape of the cutaneous lesions have been reported. So far, five cases in which the lesions were exclusively located in the nipple area have been reported, all in Korean women. Four of these cases mimicked eczema and one, a polypoid nodule. The aim of this article is to present clinical, histopathological, and immunohistochemical features of two additional cases in Brazilian women with similar nipple topography.


O acantoma de células claras ou acantoma de Degos é uma doença bem individualizada quanto aos seus aspectos clínicos, histopatológicos e imuno-histoquímicos. Sua natureza patológica - se neoplásica ou reativa - ainda é debatida por pesquisadores. De evolução crônica, ocorre predominantemente nos membros inferiores de adultos, em geral como lesão papulonodular única. Entretanto, foram observados casos com lesões múltiplas, por vezes de caráter eruptivo, e com notável variação de tamanho e forma das eflorescências cutâneas. Há relatos de cinco casos com localização exclusiva na aréola e no mamilo, quatro simulando eczema e um como nódulo polipoide; todos ocorridos em mulheres coreanas. O objetivo deste trabalho é apresentar os aspectos clínicos, histopatológicos e imuno-histoquímicos de dois novos casos da doença, com idêntica topografia areolomamilar, observados em mulheres brasileiras.

ABSTRACT

FUNDAMENTOS: Doenças Sexualmente Transmissíveis em crianças permanecem um problema de saúde pública pouco estudado, sendo ainda necessários esclarecimentos sobre seu manejo e a relação destas com o abuso sexual infantil. OBJETIVOS: Descrever o perfil clínico-epidemiológico das Doenças Sexualmente Transmissíveis em crianças atendidas em centro de referência na cidade de Manaus. MÉTODOS: Realizou-se estudo descritivo exploratório para verificar características clínicas, epidemiológicas e laboratoriais das Doenças Sexualmente Transmissíveis em crianças atendidas durante o período de janeiro/2003 a dezembro/2007. RESULTADOS: Foram incluídas no estudo 182 crianças que apresentavam DST. A maioria era do sexo feminino (65,4 por cento) e de cor parda; a média de idade foi de 8,5 anos; 89 por cento eram procedentes da cidade de Manaus; os pais foram os principais acompanhantes na consulta; verruga genital foi o principal diagnóstico em ambos os sexos; e, 90,1 por cento apresentavam apenas uma DST. CONCLUSÃO: As frequências e características clínicas das DST nas crianças do estudo não diferiram do encontrado na literatura. Embora, com base em sinais e sintomas referentes tão somente às DST nas crianças, não se tenham parâmetros fidedignos de confirmação de abuso, deve-se sempre estar alerta para esta possibilidade, visto que estas doenças podem ser sinalizadoras de ofensas sexuais, por vezes, dissimuladas e repetidas.


BACKGROUND: Sexually transmitted diseases in children remain a public health concern that is relatively ignored. Further data are required on the management of these diseases and their association with child sexual abuse. OBJECTIVES: To describe the clinical and epidemiological profile of sexually transmitted diseases in children receiving care at a referral center in the city of Manaus, Amazonas, Brazil. METHODS: A descriptive, exploratory study was conducted to evaluate the clinical, epidemiological and laboratory characteristics of the sexually transmitted diseases (STD) found in children who received care at this clinic between January 2003 and December 2007. RESULTS: A total of 182 children with STDs were included in the study. The majority were female (65.4 percent), dark-skinned and with a mean age of 8.5 years. Furthermore, 89 percent were from the city of Manaus and their parents were usually responsible for having brought them to the clinic. Genital warts constituted the principal diagnosis in children of both sexes and 90.1 percent of the children had only one STD. CONCLUSIONS: The frequencies and clinical characteristics of the STDs in the children in this study were similar to data reported in the literature. Although the signs and symptoms of the STDs found in these children do not, in themselves, constitute reliable parameters by which to confirm abuse, professionals should always be alert to this possibility, since these diseases may represent a sign of sexual offenses that may be dissimulated and repetitive.
