Qualidade dos encaminhamentos da atenção primária a um serviço de dermatologia / Quality of referrals from the primary health care to a dermatology service

Resumo Introdução Queixas dermatológicas são frequentes e em sua maioria são avaliadas por médicos não especialistas. Objetivo Analisar a proporção de pacientes encaminhados para dermatologia que poderiam ter sido tratados na Atenção Primária à Saúde e o grau de concordância entre o diagnóstico de encaminhamento do médico da Atenção Primária à Saúde e o diagnóstico do dermatologista. Método Estudo retrospectivo com abordagem quantitativa, com dados coletados de 194 prontuários, entre 2014 e 2015. O grau de concordância foi analisado pelo coeficiente Kappa, com significância de 5%. Resultados A média de idade foi 46,7 anos (dp = 17,9), sendo a maioria mulheres. Os diagnósticos de encaminhamento mais frequentes relatados pelos médicos da Atenção Primária à Saúde foram doenças eritemato-descamativas (8,0%) e câncer de pele (6,0%). Em 40,3% dos casos não havia o preenchimento do diagnóstico de encaminhamento. Os diagnósticos mais frequentes relatados pelo dermatologista foram lesões pré-malignas (15,6%) e tumores benignos (12,4%). A proporção de pacientes encaminhados que poderia ter sido tratada na Atenção Primária à Saúde foi de 37,1%. O grau de concordância Kappa foi moderado. Conclusão Os resultados sugerem dificuldades no diagnóstico das dermatopatias que foram referenciadas ao serviço de dermatologia.

Abstract Background Dermatologic complaints are frequent, and are the most frequent diagnoses performed by non-specialist doctors. Objective This study aimed to analyze the proportion of patients referred to dermatology who could have received treatment in Primary Health Care (PHC), and the degree of agreement between the referral diagnoses of PHC physician and the diagnosis of the dermatologist. Method This is a retrospective and quantitative study. The team collected data from 194 medical records between 2014 and 2015. Kappa coefficient was used to calculate the degree of agreement, with a significance level of 5%. Results The mean age was 46.7 years (SD=17.9), most of them women. The most frequent diagnostic hypotheses made by the PHC physician were desquamative erythematous diseases (8.0%) and skin cancer (6.0%). There was no completion of the referral diagnosis in 40.3% of the cases. The most frequent diagnoses made by the dermatologist were premalignant lesions (15.6%) and benign tumors (12.4%). The proportion of referrals that could have been treated in primary care was 37.1%. The diagnostic agreement was moderate (Kapa coefficient). Conclusion These findings suggest difficulties in the diagnosis of skin diseases referenced to the dermatologist.

Bob marley's disease: cerebral metastasis of acral melanoma / A doença de Bob Marley: metástases cerebrais de melanoma acral

Bob Marley's had a great importance to Jamaica, Caribbean popular music, and Pan-Africanism. Under the name of the Wailers, several Marley's success reggae albums were recorded between 1969 and 1975. After this, at the solo career, he was placed as the most important reggae singer. The disease that ruined Bob Marley was an acral melanoma (right hallux) that had a late diagnosis and treatment, followed by metastases to the abdomen, the lungs and the brain. Seizures have been the warning sign that the melanoma had spread, three years after the initial injury. We presented here the history of the disease of this famous singer and reported another patient with a case quite similar to him, calling his illness as "Bob Marley's disease".

Bob Marley representou um marco para a Jamaica, para a música popular do Caribe, e para o Pan-Africanismo. Com o nome de Wailers, vários álbuns de reggae foram gravados com sucesso entre 1969 e 1975. Em sua carreira solo, ele foi considerado o mais importante cantor de reggae. A doença que dizimou Bob Marley foi um melanoma acral (hálux direito) que teve um diagnóstico e tratamento tardios, seguido de metástases para o abdome, pulmões e encéfalo. Crises convulsivas foram o sinal de alerta, três anos após a lesão inicial, de que o melanoma estava disseminado. Nós apresentamos aqui a história da doença deste famoso cantor e relatamos um outro paciente com um caso similar ao qual denominamos "doença de Bob Marley".

Analysis of the histomorphologic profile of invasive cutaneous squamous cell carcinoma from 2002 to 2011 in a pathology laboratory in the region of Campos Gerais, Brazil.

Squamous cell carcinoma is the second most common type of malignant skin cancer. It is also quite aggressive. The increasing incidence of the disease can be altered given its connection with sun exposure. The aim of this study was to establish the clinical and histomorphological profile of squamous cell carcinoma in the region of Campos Gerais, State of Paraná, Brazil and analyze and compare the features of the disease found in the literature. We conducted a cross-sectional descriptive study in a pathology laboratory with selected invasive cutaneous squamous cell carcinoma reports issued after excisional biopsy from January 2002 to December 2011. We selected 374 cases of head and neck SCC, mean age 71.53 years, with a predominance of male patients, moderate degree of histological differentiation, Clark level IV, and absence of perineural, neural, or angiolymphatic invasions. Our results differ on some points from those found in the literature.

Influência do envelhecimento na qualidade da pele de mulheres brancas: o papel do colágeno, da densidade de material elástico e da vascularização / Influence of aging on the skin quality of white-skinned women: the role of collagen, elastic material density, and vascularization

INTRODUÇÃO: O objetivo deste estudo é avaliar a influência do envelhecimento na qualidade da pele de mulheres brancas, analisando o colágeno, as fibras elásticas e a vascularização. MÉTODO: Foi realizada análise histológica e morfométrica de 218 retalhos pré-auriculares de mulheres brancas, que se submeteram a cirurgia estética facial. Foram utilizados o imunomarcador AntiCD 34, que evidencia os vasos sanguíneos, a coloração de Weigert, para visibilização das fibras elásticas, e a coloração de Picrosirius Ultrared, para analisar e quantificar os colágenos I, III e total. Os dados foram analisados de acordo com a faixa etárias das doadoras: < 40 anos, 40 anos a 49 anos, 50 anos a 59 anos, 60 anos a 69 anos, e > 70 anos. RESULTADOS: Foi observada fragmentação e desorganização das fibras de colágeno, especialmente acima de 60 anos. Não houve diferenças significantes entre a idade e a espessura da derme e da epiderme, porém foi identificada relação com as porcentagens de colágeno I, III e total (P < 0,001). Houve aumento da densidade de fibras elásticas com a progressão da idade (P < 0,001). Comparando-se as peles das pacientes de faixas etárias vizinhas, com diferença de uma década entre elas, não houve diferença significativa na quantidade de material elástico dessas peles; porém, ao se comparar aquelas com diferença de 2 ou mais décadas nas faixas etárias, o aumento foi significante (P < 0,05). A diferença do número de vasos não foi significante (P = 0,112). CONCLUSÕES: O envelhecimento promoveu redução do colágeno, degradação e fragmentação das fibras, e aumento da densidade de material elástico desorganizado, e não influenciou no número de vasos sanguíneos da derme.

BACKGROUND: In the present study, we aimed to evaluate the influence of aging on the skin quality of white-skinned women by assessing collagen levels, elastic material density, and vascularization. METHODS: Histological and morphometric analyses were performed on 218 preauricular skin fragments from white-skinned women who underwent facial cosmetic surgery. Anti-CD34 was used to identify the blood vessels, Weigert's staining was used to visualize elastic fibers, and Picro-sirius Ultra Red staining was employed for analyzing and quantifying the expression of type I, III, and total collagen. Data were analyzed according to the following donor age groups: < 40, 40-49, 50-59, 60-69, and > 70 years. RESULTS: Fragmentation and disorganization of collagen fibers were observed in certain samples, particularly in samples from patients aged > 60 years. Significant differences between age and the thickness of the dermis and epidermis were not detected. However, a relationship was identified between age and the percentages of type I, III, and total collagen, and an increase of elastic fibers density was associated with age progression (P < 0.001). The comparison of the skin of patients with a decade difference in age did not reveal a significant difference in the elastic material quality; however, when the age difference was of 2 decades or more, there was a significant difference in elastic fibers (P < 0.05). The difference in the number of blood vessels between the groups was not significant (P = 0.112). CONCLUSIONS: Aging promoted collagen reduction, fiber degradation and fragmentation, and increased disorganized elastic material density; however, it did not affect the number of dermal blood vessels.

Influence of aging on the quality of the skin of white women: the role of collagen.

PURPOSE: Evaluate the influence of aging on the quality of the skin of white women, analyzing the dermal collagen. METHODS: Pre-auricular flaps were collected for histological and morphometric analysis of 218 white women who underwent spontaneous facial aesthetic plastic surgery. Picrosirius ultrared stain was used for analysis and quantification of collagen in five age groups (<40 years, 40 to 49 years, 50 to 59 years, 60 to 69 years and 70 to 79 years) . RESULTS: Histological analysis showed changes suggestive of skin aging (fragmentation and disorganization of collagen fibers), especially in patients over 60 years. There were no significant changes in the relationship of age with the thickness of the dermis and epidermis, but there was with the percentage of the collagen I, III and total (p<0.001), which decreased with increasing aging. CONCLUSION: There is reduction in collagen with increasing age, and an increase in its degradation, leading to fragmentation of the fibers.
