Objective: To assess mothers’ knowledge on sun exposure related to serum vitamin D levels in the neonatal period. Methods: Observational, analytical and cross-sectional study, carried out from August 2020 to May 2021 through a questionnaire directed to mothers of newborns, in a maternity hospital in Southern Brazil. Results: From 141 interviewees, 132 (93.6%) believe it is important to expose the neonate to sun, 101 (71.6%) think this exposure can increase vitamin D levels, 86 (61%) received such information from a doctor, 108 (76.6%) believe there are no risks of sun exposure, 88 (62.4%) claim it isn´t necessary to use any kind of protection, 96 (68.1%) said that only exposure to the sun was necessary to maintain adequate levels of vitamin D during the neonatal period. Only two mothers (1.4%) claim that you should not exposure the neonate to the sun, and only one (0.7%) stated that sun expose can cause skin problems. Conclusions: Most mothers lack satisfactory knowledge about sun exposure related to serum vitamin D levels in the neonatal period. The need to inform and clarify the population about sun exposure during this period is remarkable, in addition to disseminating the proper way to maintain serum levels of vitamin D.

"Non-melanoma" skin cancer is the most common neoplasm worldwide. It is noteworthy that skin cancer is on the rise around the world and symbolizes high social and financial costs for society, as well as for the health system. However, it is a preventable disease. It is believed that academics in the health area should be proactive agents in primary health care activities, including practices for the prevention of skin cancer. For this, it is necessary that the academic is updated with the protocols regarding this topic. The objective of this work is to evaluate the knowledge of academics in the health area regarding the use of photoprotection and the risk factors for skin cancer. The study population was predominantly composed of young students, with a mean age of 22 years, female, with fair skin and dark hair and eyes. The research revealed discrepancies between knowledge and practice of photoprotective measures in the daily lives of these students. However, the results obtained bring benefits, revealing the critical-reflexive need for the participants. [ABSTRACT FROM AUTHOR]

Given its importance and multidimensionality, health plays an essential role in the public policy field. Skin cancer is the most common type of neoplasm found in Brazil and is considered a public health problem. In this regard, this research addresses the issue of skin cancer with a diagnosis of its incidence in the municipality of Campos dos Goytacazes, Rio de Janeiro State, Brazil, based on the Hospital Cancer Registry (RHC, abbreviation in Portuguese). These records obtained data from all patients seen at a reference hospital (Hospital Escola Álvaro Alvim) who were diagnosed with skin cancer between 2012 and 2017, totaling 656 cases. A descriptive statistical analysis of variables such as age, occupation, tumor location, neighborhood, and gender was used to profile skin cancer patients in the municipality, identifying the sectors of the area where the local population is most affected by the disease, besides any environmental factors that may be related and the most affected race. The results of the study demonstrate that the light-skinned population (69.1%) and the age group over 55 years old (predominantly from 70 to 74 years for basal cell carcinomas and from 80 to 84 years for squamous cell carcinomas) constitute the most affected group by skin cancer. This information should support public policies and campaigns among the population aiming to improve strategies for its prevention and early diagnosis. [ABSTRACT FROM AUTHOR]

Objetivo: Averiguar a efetividade da utilização da cirurgia de MOHS no manejo de tumores cutâneos tipo não melanoma em comparação a outros métodos de terapia. Métodos: O estudo consiste em uma revisão sistemática, cuja coleta de artigos ocorreu nas bases de dados MEDLINE, PubMed Central (PMC), LILACS e SciELO, utilizando os termos “Cirurgia de MOHS”, “Câncer de pele”, “Ensaio clínico”, excluindo “melanoma”. Resultados: Do total de 132 artigos identificados, foram considerados elegíveis 11. A análise dos artigos demonstrou que a CMM, comparada a outros métodos, apresentou resultados estéticos melhores, além de menor grau de complicações em tumores recorrentes e um custo/benefício variável com o país onde foi feita operação. A CMM também apresentou menores índices de recorrência em todos os estudos. Conclusão: No geral, a cirurgia de MOHS se mostrou um método terapêutico promissor. No entanto, existem ainda poucos estudos comparativos sobre a eficácia da CMM e os que existem se concentram em poucas regiões do mundo.

Skin cancer is the most common malignant neoplasm in the occidental population, and it is important to performed studies that assess its impact on the general population and, in the current scenario, estimate the proportion of the impact of the pandemic on the diagnosis and treatment of this neoplasm. This article describes data from medical consultation in a skin cancer screening program in Espírito Santo (Brazil), carried out between March and December 2019 and March 2020, due to stoppage because of the pandemic, with frequency analysis of gender variables, diagnosis and conduct. In the comparative analysis of 2019 with 2020, there was a significant drop of 88.76% in the diagnosis of possible skin cancer lesions, in addition to a drop in procedures (scheduling in specialized services, biopsies, surgeries, cryotherapy and general guidelines for photoprotection). COVID-19's restrictions and precautionary measures to control the pandemic, responsible for the project's stoppage, also impacted several health services, in addition to the ceasing of screening programs in Brazil and abroad, significantly reducing the early diagnosis of cancer of the skin as well as its treatment in early stages.

Introdução: A campanha de fotoeducação, por meio da interação dialógica entre os atores sociais (universidade e escola), pode ser o primeiro passo para o estabelecimento de uma política de educação em saúde. A equipe de saúde da Farmácia Universitária da Universidade Federal do Rio de Janeiro vem desenvolvendo atividades em escolas públicas do município do Rio de Janeiro para a promoção da saúde por meio da educação. Objetivo: compilar e divulgar as atividades do projeto de extensão da Farmácia Universitária da Universidade Federal do Rio de Janeiro em escolas públicas da cidade do Rio de Janeiro. Metodologia: Um levantamento bibliográfico sobre fotoeducação foi realizado e as informações obtidas foram repassadas para graduandos do curso de pintura da Universidade Federal do Rio de Janeiro que participaram de sessões de orientação acerca das ações e, então, elaboraram atividades lúdicas para alunos daquelas escolas. Resultados: Foram realizadas duas campanhas com 75 participantes no total. Considerações finais: As atividades realizadas foram um instrumento de disseminação do conhecimento e possibilitaram acesso à informação aos alunos que participaram do processo, tornando-os transmissores de conhecimento em suas comunidades. Alunos de graduação e pós-graduação foram protagonistas em seu processo formativo e adquiriram responsabilidade social pela inserção das atividades de educação em saúde.

O câncer de pele é uma dermatose comum entre os seres humanos, sendo de etiologia multifatorial, na qual são considerados fatores como predisposição genética, exposição a fatores ambientais de risco e outros. Dentre a classe trabalhadora que apresenta grande risco em desenvolver o câncer de pele, estão os trabalhadores rurais, pois estes passam um longo período exposto às radiações solares. O objetivo deste trabalho foi levar informações referente à prevenção ao desenvolvimento do câncer de pele voltado a alunos do curso de Zootecnia, por meio de atividades que informavam as maneiras adequadas de exercerem suas atividades acadêmicas com segurança, uma vez que estão mais expostos aos raios solares devido às suas práticas acadêmicas. Trata-se de um relato de experiência desenvolvido com alunos do primeiro período do curso de Zootecnia de uma instituição pública da cidade de Ceres no estado de Goiás, entre os anos de 2018 e 2019. As atividades foram desenvolvidas visando abordar temas relacionados ao câncer de pele e à fotoproteção. Foi possível identificar que os alunos possuíam baixo conhecimento sobre tema. Tal padrão de conhecimento pode ser justificado pelo fato de os mesmos estarem cursando o primeiro período do curso de Zootecnia, etapa na qual são ministradas disciplinas básicas como introdução a zootecnia, metodologia científica, anatomia animal, em que são trabalhados conteúdos relacionados ao tema. Através desta atividade extensionista, foi possível obter uma experiência acadêmica de extrema relevância e tentar gerar conscientização sobre o câncer de pele e a importância da fotoproteção.

A exposição excessiva à radiação solar (RS) é o principal causador do câncer de pele. O objetivo desse trabalho foi investigar a percepção de estudantes do ensino médio sobre RS e suas implicações à saúde humana. Os dados foram coletados através de questionários e as respostas foram avaliadas por tabelas de frequências relativa, absoluta e percentual. Devido ao tamanho da amostra, utilizamos o teste de Fisher a 5% de significância (e hipótese alternativa bilateral) para correlacionar as respostas. Os alunos, independente de terem estudado ou não sobre RS não sabem definir RS e não têm percepção sobre os efeitos da RS à saúde humana. Este diagnóstico mostra, por um lado, a carência conceitual dos estudantes. Por outro, ele sugere também a ineficácia dos recursos didáticos convencionais e meios de informação acessíveis. Portanto, a inserção deste conceito na educação básica é primordial dada sua relevância social e por se tratar de um problema de saúde pública.

Fotodermatoses são patologias cutâneas de origem multifatorial, que apresentam a exposição solar excessiva como o principal fator de risco, podendo causar neoplasias de pele. Ações educacionais, conhecidas como fotoeducação, são necessárias para conscientizar a população sobre a correta exposição ao sol e orientar condutas saudáveis em fotoproteção. O objetivo deste trabalho foi desenvolver um material educativo sobre fotoproteção e prevenção de fotodermatoses no ambiente escolar. Para tal, foi realizado um estudo qualitativo descritivo, baseado em relatos de experiências, sobre as atividades realizadas no ambiente escolar. Materiais informativos sobre as características gerais do câncer de pele, os medicamentos fotossensibilizantes, o uso correto do protetor solar e a adequada exposição solar foram elaborados após a interação dialógica entre os alunos de graduação de Farmácia e da Escola de Belas Artes, ambos da Universidade Federal do Rio de Janeiro, sob supervisão de farmacêuticos da Farmácia Universitária. Além disso, foi elaborado um quiz semiestruturado com perguntas e respostas e um quebra-cabeça, a fim de que os alunos fossem participantes ativos no processo de ensino-aprendizagem. A campanha foi realizada em escolas públicas, totalizando 230 alunos, que participaram de uma roda de conversa e dos jogos propostos. Ao final da campanha, notou-se que a ação educativa foi efetiva e com elevada participação dos alunos das escolas. Os materiais informativos elaborados com os jogos e rodas de conversas foram eficientes no esclarecimento das dúvidas e considerados ferramentas importantes no processo de aprendizagem dos jovens. Palavras-chave: Câncer de pele, Fotoproteção, Promoção da saúde Health photoeducation actions in the school environment as a strategy for the prevention of photodermatoses Abstract: Photodermatoses are cutaneous pathologies of multifactorial origins, which have excessive sun exposure as the leading risk factor, causing skin neoplasms. Educational actions, known as photoeducation, are necessary to aware the population about the correct exposure to the sun and guide healthy behaviors regarding photoprotection. The work aimed at developing educational material about photoprotection and the prevention of photodermatoses in the school environment. Thus, a qualitative descriptive study was carried out, based on experiences about the school environment's activities. Informative materials about skin cancer's general characteristics, photosensitizing drugs, correct use of sunscreen, and adequate sun exposure were created after the dialogical interaction between undergraduate students of Pharmacy and Fine Arts School, both from the Federal University of Rio de Janeiro, under the supervision of pharmacists from the University Pharmacy. Also, a semi-structured quiz with questions and answers, and a puzzle was elaborated so that the students were active participants in the learning process. The campaign was carried out in public schools, with 230 students who participated in a conversation circle and the proposed games. At the end of the campaign, the educational action had a high participation rate and was considered effective. The informative materials developed, together with games and conversation circles, were efficient in clarifying doubts and considered important tools in the learning process of the young people.

This paper describes a case of a 71-year-old female who initially went to a dermatologist to assess a scalp skin tumor, which performed an incisional biopsy. Anatomopathological and immunohistochemical study revealed a preliminary diagnosis of breast carcinoma metastasis. Although the patient had no medical history of breast cancer, due to this result, she was referred to a mastologist, who investigated her breast nodules for the possible primary focus of the carcinoma. Despite an active investigation through imaging tests, biopsies, and mammotomy, without finding any possible primary focus on the breasts. Finally, the lesion on the scalp was entirely removed by a plastic surgeon. New anatomopathological and immunohistochemical exams confirmed the diagnosis of breast carcinoma metastasis. Given these results, the authors discuss the difficulty in diagnosing differentiation from a primary or metastatic neoplasm of the scalp, with the resources currently available, until the conclusion that it was a primary carcinoma of the sweat gland.

Introduction: The action of ultraviolet rays can cause several damages to the human being, being skin cancer and photoaging the most studied. Ultraviolet rays facilitate gene mutations and suppress the skin's immune system. Objective: to carry out a literature review on the characteristics of sunscreens and their mechanism of action. Development: The application of photoprotectors as a direct method of protection has been widely discussed in the literature, being suggested for the care of all skin neoplasms. Intrinsic factors influence the existence of these or not, but the geographic location and some precautions such as the use of sunscreen and the appropriate time to receive the incidence of sunlight contribute directly to the appearance or not of cancer and photoaging. Final considerations: the present study made it possible to verify the relationship between the increased incidence of skin cancer cases and other related problems caused by excessive sun exposure, with sunscreen being the main barrier to prevent these damages.

The cause of cancer in patients remains a mystery. Various theories and assumptions do not give confidence in understanding the cancer process. Until the etiology of cancer is studied, we will not be able to move forward despite the development of pharmaceutical technologies and innovative treatments. To solve this problem, it is intended to use all data related to cancer development, even if they have no obvious link to the disease. Even when a cancer cell appears and starts creating its pool of altered cancer cells we don 't know. Doctors diagnose cancer, when the tumor reaches certain sizes and disorders the function of the organ. The number of cancer cells increases very quickly. The factors that accelerate this reproduction of cancer cells are many, which means that we still do not see the true cause. The cancer cell retains the features of the original cell to varying degrees from pronounced similarity to almost complete loss of healthy cell properties. The more the foreign cell is altered, the faster it grows and the prognosis for the patient is deteriorated. The most worrying thing is that the incidence of cancer is increasing, which means the cause is not found. Cancer deaths remain high. This article discusses the case of a patient having a limb amputated for cancer (foot skin cancer). During a 10-year study of bone marrow from the femur, for the first time, bone marrow was obtained from the femur of a patient with cancer. The findings could help researchers and doctors better understand the cancer process and look at the problem differently. [ABSTRACT FROM AUTHOR]

Skin cancer is the most common neoplasm in Brazil. It corresponds to 33% of all diagnoses performed. Multiple elements are involved and related to the risk factors of this disease, such as older adults, education level, occupation, sun exposure, and use of medications as, for example, hydrochlorothiazide. This pathology is treated by means of surgical resections with safety margins. Therefore, the goal of this study was to raise the profile of patients with nonmelanoma skin cancer, undergoing surgical procedures at a hospital in the State of São Paulo, Brazil, determining their sociodemographic characteristics, in addition to describing risk factors, location of lesions, and surgical treatments. This is a descriptive, retrospective, exploratory study based on a quantitative approach. One hundred thirty-two patients were selected. Half of them were men and half women, mostly Caucasians (88.64%), older adults (87.12%), retired (36.36%), and hypertensive (74.24%). Most of them did not use hydrochlorothiazide as antihypertensive therapy (73.48%). Solid basal cell carcinomas (41.67%) and nasal location (31.06%) were the most common. The data collected indicated that the risk factors were similar to those described in the literature. The surgical procedures performed were safe, with a low rate of complications. Only color/race/ethnicity was statistically associated with the diagnoses. [ABSTRACT FROM AUTHOR]

Segundo a Sociedade Brasileira de Dermatologia, o câncer de pele corresponde a aproximadamente 33% de todos os diagnósticos da doença no Brasil, e são registrados, a cada ano cerca de 180 mil novos casos, pelo Instituto Nacional do Câncer (INCA). Trata-se de uma doença com crescimento descontrolado e anormal das células da pele, sendo dividida em câncer de pele não melanoma, os mais comuns, e melanoma cutâneo, um dos mais agressivos. Dentre os cânceres de pele não melanoma (CPNM), o carcinoma basocelular é o mais prevalente na população. Embora, apresente baixa letalidade, corresponde a uma neoplasia que vem exibindo novos comportamentos clínicos e epidemiológicos. O presente relato de caso tem a oferecer com um sub-tipo de carcinoma basocelular (CBC) de característica agressiva e de menor incidência na população acometida, contribuindo com seu diagnóstico e a forma de tratamento escolhida para seu devido reparo, uma vez que, a reconstrução dos defeitos cirúrgicos gerados pela excisão de tumores constitui um desafio para os cirurgiões. Sendo assim, de forma a reduzir os danos estéticos e a morbidade, o estudo reside em apontar direções aos profissionais quanto ao diagnóstico e métodos terapêuticos.

A mutilação da face pode ocorrer devido à remoção cirúrgica de cânceres ou traumas na região, com importante prejuízo estético e funcional. Tais mutilações provocam alterações morfológicas, funcionais e psicossociais podendo levar o indivíduo ao isolamento social e familiar, ou mesmo deixa-lo estigmatizado. Assim, é imperativo que os profissionais da saúde, especialmente os cirurgiões-dentistas, participem de sua reabilitação. Nesse aspecto, as técnicas de osseointegração têm se destacado na reabilitação desses pacientes como método de fixação, entretanto, nem todos os pacientes podem se beneficiar delas, seja devido a obstáculos financeiros ou a contraindicação inerente à sua condição. O objetivo deste trabalho é descrever o caso da reabilitação de um paciente com perda de grande parte do apêndice nasal devido a um cirurgia oncológica. Paciente do sexo feminino, com 77 anos de idade compareceu apresentando perda de grande parte do apêndice nasal devido a uma cirurgia para ressecção de lesão de câncer de pele seguida de radioterapia adjuvante. A condição sistêmica da paciente contraindicava a realização de cirurgia reparadora e o uso de implantes osseointegráveis. Assim, optou-se pela reabilitação com prótese nasal de resina acrílica óculo-suportada. Em conclusão, com o procedimento empregado, a paciente apresentou melhora em sua respiração, estética e qualidade de vida, favorecendo usa reinserção à vida social.

The cancer is characterized to present uncontrolled cellular growth, which leads to the formation of an agglomerated of cells with no function in the organismo, subsequently this cells can move to other organs causing metastasis. This study aimed to evaluate knowledge among health comunitary agentes about the evil effects caused to the skin through the solar radiation and mechanism of protection against the skin cancer. The research is descriptive exploratory cross-sectional character of a qualitative and quantitative approach, which a questionnaire was applied to obtain data. The age group with the highest rate of skin cancer is 40 to 60 years, age associated to the results obtained in the research. Which exposes itself daily to sunlight, without all the ideal protection mechanism, being among the main group at risk for skin cancer. This work showed the lack of knowledge of the researched public about the evil that lack of protection can cause evidencing the need to carry out campaigns on the dangers related to skin cancer and and means of protection for an awareness of the population about the risks they are exposed.

The long exposure to the sunshine can cause damages on the cells of the epithelial tissue. The goal of this research is to present the data about the number of people that were diagnosed with skin cancer and the description of the types of skin with the highest levels of incidence in the development of skin dermatoses in the state of Rondônia, north region of Brazil, taking in consideration the period of five years, comprising the years from 2013 to 2017. This epidemiological study is the transversal type, retrospectively. The data was acquired with the Brazilian Society of Dermatology (SBD). Two hundred and ninety eight cases of skin cancer were registered during the analyzed period of time, thus 92% corresponds to non-melanoma cancer and 8% to malignant melanoma. The results obtained show high percentage of white skin people with skin cancer (67%), next the brown skin people sum 30% and the black skin 2%. The yellow skin corresponded to 1% of all cases. The index of skin cancer is considered high on people with light skin in the state of Rondônia, evidencing the predisposition of people with this feature in developing dermatological neoplasias, however preventive programs show themselves to be efficient in fighting skin cancer.

Nowadays, concern over skin cancer has been growing more and more, especially in tropical countries where the incidence of UVA/B radiation is higher. The correct use of sunscreen is the most efficient way to prevent the development of this disease. The ingredients of sunscreen can be organic and/or inorganic sun filters. Inorganic filters present some advantages over organic filters, such as photostability, non-irritability and broad spectrum protection. Nevertheless, inorganic filters have a whitening effect in sunscreen formulations owing to the high refractive index, decreasing their esthetic appeal. Many techniques have been developed to overcome this problem and among them, the use of nanotechnology stands out. The estimated amount of nanomaterial in use must increase from 2000 tons in 2004 to a projected 58000 tons in 2020. In this context, this article aims to analyze critically both the different features of the production of inorganic filters (synthesis routes proposed in recent years) and the permeability, the safety and other characteristics of the new generation of inorganic filters.

A exposição aos raios ultravioletas tem provocado o aumento da incidência do câncer de pele, geralmente associados a alterações na estrutura do DNA. Bancos de dados genômicos permitem o acesso público às sequencias de DNA que podem ser comparadas e analisadas, tais como o gene P53, que está relacionado ao tipo de câncer de pele com maiork incidência. Esta pesquisa visa implantar metodologias de análise comparativa de sequências de nucleotídeos para a avaliação de impactos ambientais. Estão sendo realizadas investigações para averiguar as mais frequentes mutações no gene em bancos de dados de populações oriundas de países com diferenças contrastantes. A sequência original do gene será comparada com sequências mutantes descritas em pacientes com câncer de pele, através de uma ferramenta de bioinformática. Estão sendo realizados estudos comparativos, de modo a estabelecer correlações entre as mutações mais frequentes e fatores ambientais que possam estar relacionados com a origem das mutações.

The study aimed to establish the canine skin cancer prevalence in cases analyzed in the Animal Pathology Laboratory of the Federal University of Parana, Sector Palotina between 2010-2013.

A Radiação Ultravioleta (R-UV) possibilita a síntese de vitamina D na pele humana; todavia, quando a exposição é elevada ela pode causar danos à saúde, como o câncer de pele. Para analisar a relação entre a dimensão espacial da R-UV (convertida em Índice Ultravioleta - IUV) e o câncer de pele no Brasil utilizou-se da concepção sistêmica, sendo que foram empregados dados da doença (INCA - Instituto Nacional do Câncer) e dados de IUV (CEPETEC – INPE: Instituto Nacional de Pesquisas Espaciais). No estudo foram evidenciados os fatores que se associam na definição de um padrão de pessoas com maior risco de desenvolver câncer de pele (pele clara), tanto devido à condição ambiental (R-UV) e espacial (região Sul) quanto sócio-econômica (baixa renda) que, juntas, conduzem a maior vulnerabilidade de desenvolver a doença. Não foi realizada correlação entre IUV e dados de câncer de pele, devido ao fato dos efeitos dos raios solares serem cumulativos. O câncer de pele é um problema de saúde pública, sendo o conhecimento de suas variações espaciais um dado importante para sua prevenção e combate.

The city of Rio Grande ranks second in skin cancer in the state of Rio Grande do Sul, Brazil. Current study investigates the epidemiological profile of people attended to in the campaign against skin cancer in Rio Grande in 2010, 2011 and 2012. Participating and semi-directed observations were undertaken. White and brown-skinned females participated most, although males were on the increase. At least, 50% of the participating population expose themselves to the sun without any protection, especially during their occupational activities. Solar protection is not sufficiently used: in 2010 and 2011, the percentages of people who failed to use solar protectors were respectively 53.01% and 45.58%. Contrastingly, percentages were similar to those who never had sun burns and those with more than three episodes, similar to percentages of who never had and who had a previous skin cancer episode. All agreed on the importance of being informed on daily UV radiation and health risks. All agree that the school is the most appropriate place to disseminate information and discuss such issues. Data suggest educational and social policies on the relationship between exposure to UV radiation and skin cancer. [ABSTRACT FROM AUTHOR]

Exposure to ultraviolet rays has caused the increased incidence of skin cancer, usually associated with changes in the DNA structure. Genome databases allow public access to DNA sequences that can be compared and analyzed, such as the P53 gene, related to the type of skin cancer with the highest incidence. This research aims to establish methodologies for comparative analysis of nucleotide sequences for the assessment of environmental impacts. Investigations aiming to determine the most frequent mutations in the gene databases populations from countries with contrasting differences are being held. The original gene sequence is compared with mutant sequences described in patients with skin cancer through a bioinformatics tool. Comparative studies will be conducted in order to establish correlations between the most frequent mutations and environmental factors that may be related to the origin of the mutations.

doi: 10.5216/ree.v12i3.6156 A pele é um órgão externo e está sujeita a agressões diárias provocadas pela exposição solar. Os profissionais que exercem seu trabalho em ambientes externos estão sujeitos aos danos ocasionados pela exposição solar sem proteção, como os agentes comunitários de saúde e de combate a endemias. Nesse sentido, esse estudo teve como objetivo conhecer os hábitos de exposição solar de agentes comunitários de saúde e de combate a endemias que atuam no município de Ribeirão das Neves, Minas Gerais. Foi realizado um estudo exploratório, no ano de 2008 com a aplicação de um questionário semi-estruturado, com 7 agentes comunitários de saúde e 6 agentes de combate a endemias. Os resultados revelaram que a maior parte dos entrevistados expõe-se por mais de cinco horas diárias a radiação solar, sendo a totalidade em horário crítico; 46,17% não usam protetor solar e 23% associam métodos químicos e físicos e todos apresentaram algum agravo a pele em decorrência de sua atividade profissional. Os resultados apontam para a importância da criação e implementação de ações que motivem esses profissionais no uso de medidas de fotoproteção efetivas. Descritores: Radiação solar; Promoção da saúde; Saúde do Trabalhador.

The Photoprotection in adolescents and young adults is extremely important to be at this age that individuals remain largely exposed to the sun. Thus, de objective of this study was evaluate the habits of sun exposure and protection among medical students at the Faculty Inga, to identify risk factors for skin cancer, and based on those findings, develop a clinical training related to need for photoprotection. We applied a questionnaire containing questions about sunscreen and sun exposure habits, applied to students from first to fourth year of medicine at the Faculty Inga in Maringá-PR, from April to July 2012. Our results demonstrate that 132 questionnaires were answered by students. Predominated tone skin who burns easily and tans very little (skin type I) (39.4%), and the time of exposure to sunlight more frequently during the summer were from 10 am till 15 pm (26.51%). In addition, 69.7% responded that they do not use sunscreen daily and 22.7% said they did not use any accessory protection (shirts, hats, caps) during sun exposure. CONCLUSIONS: We found that most students, despite having clear skin, is exposed to the sun at inadequate times, do not use sunscreen daily and sun protection accessories. From these results, case studies, dealing with the risk for skin cancer were used by academics, seeking their own awareness as well as the development of clinical reasoning that can be used in their future professional practice.

Nonmelanoma skin câncer is the most common malignant tumor in Brazil. Its less common subtype, squamous cell carcinoma (SCC), can be aggressive, but it's usually completely healed with only local tharepeutic measures. The case reported is about a 75 year-old woman who had a 2,5 cm lesion on the back of the left hand diagnosed as welldifferentiated SCC. She was submitted to a resection of the tumor with surgical margins of 1,5 cm. After 75 days of surgery, the patient returned with enlarged left axillary lymph node. Biopsy was done, which concluded that it was metastatic well-differentiated SCC. The treatment proposed was axillary lymphadenectomy associated with adjuvant radiation therapy. The patient presented axillary tumor recurrence and severe local pain, being submitted to extended local resection. It was proposed to the patient the interscapulothoracic disarticulation surgery and the patient agreed to the procedure. Currently, the patient is in outpatient control, with no signs of recurrence or distant metastasis. This case shows an atypical presentation of well-differentiated SCC with the primary tumor on the back of the left hand and an axillary lymph node metastasis, with compromised quality of life. The interescapulothoracic disarticulation surgery was the treatment proposed due to the presence of a tumor locally advanced, nonfunctionality of the member, the possibility of better local hygiene and absence of metastasis at other sites.

Introduction: Skin cancer represents an important health problem in the scenario of public health in the country. Of all the malignant tumours, it accounts for 25% of all estimated new cases for 2010/2011, being ranked as the most prevalent type of cancer in our country. Objective: To conduct an epidemiological study with an ecological approach, with geostatistical tools, on the distribution of skin cancer in São Paulo. Method: It was applied the parameters of assessment and standardized incidence ratio (SIR) for the diagnosis of the disease by municipality and year of study. Spatial analysis was performed to identify risk areas. Results: The north, northwest and central state had greater values of SIR. The regions south and southeast have less expressive values of SIR. Conclusion: It was to highlight areas for the occurrence of the disease, but there are important variables that were not controlled, such as migration, which indicates the need for studies in greater detail.

Primary Cutaneous Melanoma can be defined as a primary melanoma lesion of skin that comes from a healthy skin without any clinical evidence of tumor, such as pre existing melanocytic nevi. Its origin is the result of changes in the DNA of malignant cells. Initially, melanomas have a radial growth and then vertical beyond the limits of the primary site. The diagnosis comes from a suspect and can be confirmed by a biopsy which will be examined histopathologically. According to the biopsy, which will provide features such as thickness, margins, cell type, among others, will be done the surgical excision of the tumor that is expected to exceed the clinically visible margins due to their penetrating power. Because it is a disease with high power of metastasis and mortality, early diagnosis and treatment are essential to define a better prognosis for these patients. [ABSTRACT FROM AUTHOR]
