Hidradenitis suppurativa is a chronic immune mediated disease of universal distribution that causes great damage to the quality of life of the affected individual, whose prevalence is estimated at 0.41% in the Brazilian population. The objective of this work was update on physiopathogenesis, diagnosis and classification of hidradenitis suppurativa and to establish therapeutic recommendations in the Brazilian reality. It was organized as a work group composed of eight dermatologists from several institutions of the country with experience in the treatment of hidradenitis suppurativa and carried out review on the topic. Recommendations were elaborated and voted by modified Delphi system and statistical analysis of the results was performed. The Brazilian consensus on the clinical approach of hidradenitis suppurativa had the support of the Brazilian Society of Dermatology.
BACKGROUNDMelasma is a chronic, acquired hyperpigmentation disease on sun-exposed areas of the skin, which affects patients' quality of life.OBJECTIVETo assess the impact on the quality of life of women living in Florianópolis, Brazil, through questionnaire (MelasQol), and investigate the clinical aspects and risk factors for melasma, correlating them with the MelasQol scores.METHODSThis study was performed on 51 melasma patients cared for at the University Hospital of the Universidade Federal de Santa Catarina. The variables included were: age, gender, age of onset of melasma, Fitzpatrick phototype (I-VI), duration and family history of melasma, onset of melasma during pregnancy, use of hormonal contraceptive, thyroid disorder and distribution of melasma. The MelasQoL questionnaire, validated for Brazilian Portuguese (MelasQoL-BP), was applied.RESULTSThe mean age was 38.43±6.75 years. All patients were women. The most common Fitzpatrick skin phototypes were III (49.02%) and IV (33.33%). Melasma had a mean age of onset of 29.18±7.05 years and a mean duration of 9.25±6.18 years. The majority of patients did not have familial history of melasma (50.98%). Melasma onset was associated with pregnancy (45.10%). The MelasQoL-BP analysis revealed significant emotional impact on patients, such as feeling bothered (94.11%), frustrated and embarrassed (64.71%), and depressed (52.94%) about their skin appearance, as well as unattractive (78.43%). No social impact was observed (P>0.05).CONCLUSIONMelasma has a strong emotional impact on quality of life, resulting especially from feelings about skin appearance.
BACKGROUND Dermoscopy allows the early detection of melanomas. The preoperative determination of Breslow index by dermoscopy could be useful in planning the surgical approach and in selecting patients for sentinel lymph node biopsy. OBJECTIVES This study aims at describing the dermoscopic features of thin melanomas and comparing melanomas in situ with invasive melanomas less than or equal to 1 mm thick. METHODSThis was an observational retrospective study in which the dermoscopy photographs of 41 thin melanomas were evaluated. Three observers evaluated together 14 dermoscopic criteria. RESULTS Among thin melanomas, the most frequent criteria were presence of asymmetry in two axes in 95% of cases (39 cases), 3 or more colors in 80.4% of cases (33 cases), atypical dots or globules in 58.5% of cases (24 cases) and atypical network or streaks in 53.6% of cases (22 cases). The group of invasive melanomas presented with a higher frequency and statistical significance (p <0.05) 3 or more colors (OR: 16.1), milky red areas (OR: 4.8) and blue-white veil (OR: 20.4), and a greater tendency to have streaks or atypical network (OR: 3.66). CONCLUSIONS Thin melanomas tend to have asymmetry in the two axes, 3 or more colors, atypical dots or globules and atypical network or streaks. Melanomas in situ tend to have up to 2 colors, no blue-white veil and no milky red area. Invasive melanomas tend to have 3 or more colors, a milky red area, blue-white veil, and atypical network or streaks. Further studies are needed to confirm these findings.
BACKGROUND: Vitiligo is considered the most frequent acquired hypomelanosis. Although its pathogenesis is uncertain, it is believed that autoimmune etiology is the most plausible. This theory is based on the coexistence of vitiligo with autoimmune diseases. Objectives: To describe the epidemiological profile of vitiligo patients and to estimate the prevalence of the association of vitiligo with autoimmune thyroid diseases. Methods: A cross-sectional study was conducted through analysis of the medical records of patients diagnosed with vitiligo in the AME-UNISUL Outpatient Clinic of Dermatology and at HU-UFSC. The clinical and laboratorial characteristics of these patients were assessed. Results: 85 medical records were evaluated; 56 patients were female, with a mean age of 37.14 years and mean onset age of 25.25 years. Vitiligo vulgaris occurred in 70.6%. Autoimmune thyroid diseases were found in 22.4%. Other autoimmune diseases were identified in 5.9%. Patients with positive thyroid autoantibodies showed a probability of extension of vitiligo greater than 25%. There was no statistical difference with regard to the clinical characteristics of vitiligo in patients with or without autoimmune thyroiditis with hormonal change. Conclusion: The findings of this study are similar to those obtained by other authors, showing that autoimmune thyroid diseases are more common in patients with vitiligo. Keywords: Autoimmunity; Thyroid diseases; Vitiligo Resumo: FUNDAMENTO: O vitiligo é considerado a hipomelanose adquirida mais frequente. Apesar de sua etiopatogenia ser incerta, acredita-se que a etiologia autoimune seja a mais plausível, teoria que se fundamenta na concomitância de vitiligo com doenças autoimunes. OBJETIVOS: Traçar o perfil epidemiológico dos pacientes com vitiligo e estimar a prevalência da associação de vitiligo com doenças autoimunes da tireoide. MÉTODOS: Efetuou-se um estudo transversal, analisando-se prontuários dos pacientes com diagnóstico de vitiligo atendidos no Ambulatório de Dermatologia AME-Unisul e do HU-UFSC. Avaliaram-se as características clínicas e laboratoriais desses pacientes. RESULTADOS: Foram avaliados 85 prontuários, sendo 56 do sexo feminino, com idade média de 37,14 anos e idade média de início de 25,25 anos. O vitiligo vulgar ocorreu em 70,6% dos casos. As doenças autoimunes da tireoide foram encontradas em 22,4% dos casos. Outras doenças autoimunes foram identificadas em 5,9% dos casos. Os pacientes com anticorpos antitireoidianos positivos revelaram uma probabilidade elevada de extensão do vitiligo maior que 25%. Não houve diferença estatística quanto às características clínicas do vitiligo em portadores ou não de tireoidite autoimune com alteração hormonal. CONCLUSÃO: Os resultados deste estudo são similares aos de outros autores, mostrando que as doenças autoimunes da tireoide são mais frequentes nos pacientes com vitiligo.
FUNDAMENTOS: Observa-se tendência mundial de aumento na incidência do carcinoma de células escamosas da pele, porém na região sul do estado de Santa Catarina (SC) não há dados sobre a incidência desse tipo de câncer. OBJETIVOS: Estabelecer dados epidemiológicos do carcinoma de células escamosas da pele em Tubarão (Santa Catarina). MÉTODOS: Laudos anatomopatológicos positivos para o carcinoma de células escamosas da pele dos laboratórios de Tubarão foram revisados quanto às variáveis: ano, idade, gênero, localização, subtipo histológico, maior diâmetro da lesão e comprometimento das margens. A incidência anual foi calculada utilizando o número de neoplasias encontradas e a população anual estimada para os anos de 2000, 2003 e 2006. RESULTADOS: Foi encontrada uma incidência de carcinoma de células escamosas da pele por 100.000 habitantes de 50,86 para o ano de 2000, de 71,16 para 2003 e de 94,39 para 2006. Não houve predomínio de gênero, a face foi o local de acometimento mais frequente em ambos os gêneros e o subtipo histológico mais comum foi o bem diferenciado. CONCLUSÃO: A incidência do carcinoma de células escamosas da pele encontrada superou a estimativa da literatura consultada. Houve aumento na sua incidência; as variáveis idade, localização e tipo histológico foram concordantes com a literatura, porém a distribuição quanto ao gênero se mostrou diferente.
Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.
FUNDAMENTOS: O melanoma é o câncer cutâneo com maior letalidade. Santa Catarina é o estado brasileiro com maior número de casos desse tumor. OBJETIVOS: Estimar a taxa de mortalidade por melanoma no quinto ano de doença. MÉTODOS: A amostra compreendeu 81 laudos de melanoma primário cutâneo, em 75 pacientes, emitidos em Florianópolis - SC em 2002 e 2003. O protocolo de pesquisa incluiu idade, sexo, cor do paciente e localização anatômica, tipo histológico, grau de invasão, índice de Breslow, infiltrado inflamatório, ulceração, regressão, invasão angiolinfática e estadiamento do tumor. Foi feito contato telefônico com os pacientes para verificar seu status (vivo, morto por melanoma ou morto por outra causa). Para análise estatística, utilizou-se o teste exato de Fisher e a curva de sobrevida de Kaplan-Meier. RESULTADOS: O perfil dos pacientes foi: feminino, branco, 51,3 anos, melanoma invasivo em tronco ou membros, tipo extensivo superficial, Breslow 2,63 mm. A taxa de mortalidade por melanoma cutâneo foi de 7,0%, maior entre homens (11,1%), com Breslow superior a 4,0 mm (66,0%), com ulceração (33,3%) e em estádio IV (80,0%). A sobrevida média foi de 56,7 meses. Conclusões: A taxa de mortalidade por melanoma primário cutâneo foi de 7,0%, e a ulceração e o estadiamento final foram os fatores com significância estatística sobre o resultado.
BACKGROUNDTelemedicine refers to the use of technology as improvement of healthcare delivery to places where distance becomes an obstacle. Its use represents a great potential for dermatology, a specialty whose visual analysis phase is essential in diagnosis.OBJECTIVESTo analyze the compatibility index of skin cancer diagnoses between primary care and teledermatology, and to validate a protocol for standardization of digital imaging to obtain the reports in teledermatology.METHODSAn observational cross-sectional study developed through the census of 333 examination requests, received between January/2012 and July/2012, in the Center for Telemedicine and Telehealth of SES-SC. We used a protocol for photographic lesion standardization, consisting of three steps (panoramic photo, close-up with ruler and dermoscopy). After collection, the data were sent to a virtual site on the Internet, and recorded with the use of an electronic health record containing the images, the skin phototype and demographic characteristics.RESULTSThe level of compatibility between the diagnosis of skin cancer in Santa Catarina's primary care and the diagnosis proposed by teledermatology was 19.02%. Proportionally, it was 21.21% for BCC, 44.44% for SCC and 6.98% for MM. The protocol was statistically significant (p <0.05), with an OR of 38.77.CONCLUSIONThe rate of diagnostic compatibility of skin cancer was low and the use of the protocol optimized the chance of validating requests for examination.
