Short-term qualitative and quantitative analyses of preseptal injection of hyaluronic acid on the treatment of acquired lower eyelid cicatricial ectropion / Análise preliminar qualitativa e quantitativa da injeção pré-septal de ácido hialurônico para tratamento do ectrópio cicatricial adquirido da pálpebra inferior

ABSTRACT Purpose: Recently, hyaluronic acid (HA) was proposed as a promising option for the treatment of acquired lower eyelid cicatricial ectropion. However, this effect was not confirmed by quantitative assessments. This study aimed to assess the effect of hyaluronic acid on the treatment of acquired lower eyelid cicatricial ectropion. Methods: Eight patients with acquired lower eyelid cicatricial ectropion (13 eyelids) were treated with a single 1 mL injection of hyaluronic acid in the preseptal area of the lower eyelid. Evaluation of symptoms and biomicroscopic exam was performed before and 30 days after hyaluronic acid injection. Quantitative analysis of the lower eyelid position (with and without lid traction) was determined before and 30 days after hyaluronic acid injection through standard photographs analyzed using the ImageJ. Results: All patients experienced partial improvement of symptoms. The lower eyelid position was significantly lifted after hyaluronic acid injection with a significant reduction of medial and lateral angles, reduction of the margin reflex distance, and total and medial ocular fissure area. However, signs of lid margin inflammation and corneal punctate keratitis persisted. Conclusions: Hyaluronic acid injected in the pre-septal area of the lower eyelid improved acquired lower eyelid cicatricial ectropion symptoms and significantly lifted the position of the lower eyelid. Further studies, with a large number of participants and a long-term follow-up period, are needed to better determine the permanency of the effects of hyaluronic acid injections on the treatment of acquired lower eyelid cicatricial ectropion.

RESUMO Objetivo: Recentemente, o ácido hialurônico foi proposto como promissor no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. No entanto, não foram feitas avaliações quantitativas para confirmar este efeito, motivo que levou a realização do presente estudo que visou avaliar o efeito do ácido hialurônico no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. Métodos: Oito portadores de ectrópio cicatricial adquirido da pálpebra inferior (13 pálpebras) foram tratados com uma única dose de 1 mL de ácido hialurônico, injetada na área pré-septal da pálpebra inferior. Os sintomas e o exame biomicroscópico foram realizados antes e 30 dias após a injeção do ácido hialurônico. A análise quantitativa da posição palpebral inferior (com e sem tração palpebral) foi determinada antes e 30 dias após a injeção do ácido hialurônico por meio de fotografias que foram analisadas usando o programa ImageJ. Resultados: Todos os pacientes apresentaram melhora parcial dos sintomas. A posição da pálpebra inferior foi elevada significativamente após a injeção do ácido hialurônico, com redução significativa dos ângulos medial e lateral, da distância entre o reflexo pupilar e a margem da pálpebra inferior, da área de fissura palpebral total e da área medial. No entanto, sinais de inflamação da margem palpebral e ceratite puntata da córnea persistiram. Conclusões: O ácido hialurônico injetado na área pré-septal da pálpebra inferior, melhorou os sintomas do ectrópio cicatricial adquirido da pálpebra inferior e elevou significativamente a posição da pálpebra inferior. Estudos com maior número de participantes e período de acompanhamento mais longo são necessários para melhor determinar os efeitos das injeções de ácido hialurônico a longo prazo no tratamento do ectrópio cicatricial adquirido da pálpebra inferior.

The skin through reflectance confocal microscopy -Historical background, technical principles, and its correlation with histopathology

Abstract Since its first introduction into medical practice, reflectance confocal microscopy (RCM) has been a valuable non-invasive diagnostic tool for the assessment of benign and malignant neoplasms of the skin. It has also been used as an adjunct for diagnosing equivocal cutaneous neoplasms that lack characteristic clinical or dermoscopic features. The use of RCM has led to a decreased number of biopsies of benign lesions. Multiple published studies show a strong correlation between RCM and histopathology thereby creating a bridge between clinical aspects, dermoscopy, and histopathology. Dermatopathologists may potentially play an important role in the interpretation of confocal images, by their ability to correlate histopathologic findings. RCM has also been shown to be an important adjunct to delineating tumoral margins during surgery, as well as for monitoring the non-surgical treatment of skin cancers. Advanced technology with smaller probes, such as the VivaScope 3000, has allowed access to lesions in previously inaccessible anatomic locations. This review explains the technical principles of RCM and describes the most common RCM features of normal skin with their corresponding histological correlation.

Algoritmos para manejo de cicatrizes: a importância da sistematização de condutas / Algorithms for the management of scars: the importance of systematizing behaviors

■ RESUMO Introdução: As cicatrizes patológicas ocorrem a partir de hiperproliferaçãoo de fibroblastos, podendo ser classificadas em cicatrizes hipertróficas e queloides, basicamente as cicatrizes hipertróficas não crescem além dos limites da ferida original, enquanto os queloides crescem horizontalmente de forma nodular. Apesar da diversidade de instrumentos utilizados para orientar a prevenção, tratamento e seguimento de cicatrizes patológicas, existe a necessidade de instrumentos que contemplem realidades locais. O objetivo é realizar uma revisão narrativa de literatura sobre algoritmos para manejo de cicatrizes e criar um algoritmo atualizado. Métodos: Estudo descritivo de revisão narrativa de literatura, sendo realizado uma pesquisa nas bases de dados PubMed, SciELO, LILACS, MEDLINE e Cochrane, no período de novembro de 2010 até novembro de 2020, publicados nos idiomas inglês, português e espanhol. Os descritores utilizados foram: "cicatrix", "keloid", "algorithms" e "wound healing". A seleção da amostra consistiu da identificação dos artigos, leitura dos títulos e resumos e seleção de estudos relacionados ao tema e, posteriormente, foi realizada a leitura na íntegra dos estudos selecionados e classificação segundo os critérios de elegibilidade. Resultados: Foram encontrados 209 artigos sendo eliminados 116 devido duplicidade resultando em 45 artigos. Foram identificados um total de 8 artigos que preencheram os critérios de inclusão e após análise e reunião de consenso foram excluídos quatro artigos devido à ausência de algoritmos com rigor científico sendo este estudo composto de quatro artigos. Conclusão: Foram encontrados quatro algoritmos na revisão de literatura que resultaram na elaboração de um algoritmo atualizado para cicatrizes.

■ ABSTRACT Introduction: Pathological scars occur from the hyperproliferation of fibroblasts and can be classified into hypertrophic scars and keloids. Basically, hypertrophic scars do not grow beyond the limits of the original wound, while keloids grow horizontally in a nodular form. Despite the diversity of instruments used to guide the prevention, treatment and follow-up of pathological scars, there is a need for instruments that address local realities. The objective is to carry out a narrative review of the literature on scar management algorithms and create an updated algorithm. Methods: Descriptive study of narrative literature review, with a search in PubMed, SciELO, LILACS, MEDLINE and Cochrane databases, from November 2010 to November 2020, published in English, Portuguese and Spanish. The descriptors used were: "cicatrix," "keloid," "algorithms," and "wound healing." The sample selection consisted of identifying the articles, reading the titles and abstracts, and selecting studies related to the topic. Subsequently, the full reading of the selected studies and classification according to the eligibility criteria were carried out. Results: 209 articles were found, and 116 were eliminated due to duplicity, resulting in 45 articles. A total of 8 articles that met the inclusion criteria were identified. Four articles were excluded after analysis and consensus meeting due to the absence of algorithms with scientific rigor; this study is composed of four articles. Conclusion: Four algorithms were found in the literature review that resulted in the development of an updated algorithm for scars.

Introduction: Nanofat graft improves skin quality in damage secondary to aging and scar sequelae. We present the initial results of the nanofat graft using a low-cost disposable device, proposing a standardization of its use according to the area to be treated. Methods: A prospective cohort was conducted from July 2019 to March 2020. The inclusion criterion was patients who underwent nanofat grafting for skin treatment. The exclusion criterion was the previous performance of some invasive treatment of the skin. Twenty consecutive patients who met the prerequisites were analyzed. The results were evaluated in the 6th postoperative month. The patients answered a questionnaire, classifying from 1 - very bad to 10 - excellent, changes in skin quality. Results: The twenty patients followed did not present any postoperative complications. Edema after the application was reduced between three and seven days. There was no hematoma or infection. Patients who underwent only nanofat grafting without another associated surgery could return to their activities after 24 hours. The scores reported by patients at 6 months were between 7 and 10, with a mean of 8. Conclusion: The use of the Smartneedle™ system for nanofat grafting presents patient satisfaction similar to other application methods and allows a uniform and standardized distribution of the graft according to the anatomical region and optimizing surgical time

Necrose palpebral bilateral com reconstrução por matriz dérmica e enxertia cutânea / Bilateral eyelid necrosis with dermal matrix reconstruction and skin grafting

As infeções de pele e tecidos moles constituem um grupo de patologias de elevada prevalência. A fasceíte necrotizante é a infeção rápida e destrutiva do tecido subcutâneo e fáscia superficial com elevada morbimortalidade. Mais frequente na região perineal é de ocorrência rara na região periorbitária. O relato deste caso ilustra um caso de necrose palpebral bilateral após traumatismo cranioencefálico leve com escoriações. Foi realizado tratamento clínico intensivo e desbridamento cirúrgico da área afetada. Na primeira fase da reconstrução palpebral foi usada matriz de regeneração dérmica. Este substituto cutâneo inicialmente descrito para queimaduras se reveste atualmente de grande importância em cirurgia plástica visando uma melhor e mais rápida cicatrização das feridas. Posteriormente, realizou-se a autoenxertia cutânea tendo-se obtido um bom resultado estético e funcional.

Skin and soft tissue infections are a group of pathologies of high prevalence. Necrotizing fasciitis is a rapid and destructive infection of the subcutaneous tissue and superficial fascia with high morbidity and mortality. It is frequent in the perineal region and of rare occurrence in the periorbital region. This report illustrates a case of bilateral eyelid necrosis after mild head trauma with abrasions. Intensive clinical treatment and surgical debridement of the affected area were performed. In the first phase of eyelid reconstruction, a dermal regeneration matrix was used. This cutaneous substitute initially described for burns is currently of great importance in plastic surgery, aiming to heal wounds better. Subsequently, cutaneous self-grafting was performed, and a good aesthetic and functional result was obtained.

Poroma écrino pigmentado no couro cabeludo simulando melanoma / Pigmented eccrine poroma on scalp simulating melanoma

Introdução: O poroma écrino é uma lesão benigna geralmente solitária e nodular, sendo frequente na palma da mão e planta do pé. Devido à sua raridade, a variante pigmentada pode facilmente ser confundida com melanoma. Relata-se caso clínico de poroma écrino pigmentado no couro cabeludo, localização considerada atípica, simulando melanoma maligno. Relato de Caso: Paciente do sexo masculino, 73 anos, fototipo IV, referia aparecimento de lesão indolor no couro cabeludo há 6 meses, associada a sangramentos esporádicos. Ao exame, apresentava-se como nódulo enegrecido com centro eritematoso, de consistência firme, medindo aproximadamente 1,5 cm de diâmetro. A dermatoscopia observou padrão vascular predominante em glóbulos. A principal hipótese diagnóstica foi de melanoma, porém o estudo histopatológico concluiu poroma écrino parcialmente pigmentado. Discussão: O porome écrino pigmentado é um tumor raro com fisiopatologia desconhecida. É considerado como um grande simulador por mimetizar clinicamente diversos tumores, benignos e malignos. Neste caso clínico, após o exame dermatológico e avaliação dermatoscópica, a principal hipótese diagnóstica era de melanoma maligno. Os poucos casos clínicos publicados com estudo dermatoscópico apresentaram história semelhante e dúvida diagnóstica, tendo sido esclarecido o diagnóstico somente após a avaliação histopatológica. Conclusão: É importante que a avaliação de lesões de pele pigmentadas seja feita tanto clinicamente quanto com dermatoscopia, usada como ferramenta que corrobora com o diagnóstico. A hipótese diagnóstica de poroma écrino deve ser considerada nos casos em que as lesões pigmentadas não tenham características melanocíticas, sendo o diagnóstico confirmado apenas após avaliação histopatológica.

Introduction: The eccrine poroma is a benign lesion, usually solitary and nodular, frequent in the palm and foot plant. Due to its rarity, the pigmented variant can easily be confused with melanoma. A clinical case of pigmented poroma on the scalp is reported; this is a location considered atypical, simulating malignant melanoma. Case Report: A 73-year-old male patient, phototype IV, reported the appearance of a painless lesion on the scalp for six months, associated with sporadic bleeding. On examination, it presented as a blackened nodule with an erythematous center of firm consistency, measuring approximately 1.5 cm in diameter. Dermatoscopy observed a predominant vascular pattern in blood cells. The main diagnostic hypothesis was melanoma, but the histopathological study concluded partially pigmented eccrine poroma. Discussion: Pigmented eccrine poroma is a rare tumor with unknown pathophysiology. It is considered a great simulator for clinically imitate several tumors, benign and malignant. In this clinical case, after dermatological examination and dermoscopic evaluation, the main diagnostic hypothesis was malignant melanoma. The few clinical cases published with a dermatoscopic study presented a similar history and diagnostic doubt, and the diagnosis was clarified only after histopathological evaluation. Conclusion: The evaluation of pigmented skin lesions must be done both clinically and with dermatoscopy, used as a tool that corroborates the diagnosis. The diagnostic hypothesis of eccrine poroma should be considered when pigmented lesions do not have melanocytic characteristics, and the diagnosis is confirmed only after histopathological evaluation.

Durometry as an alternative tool to the modified Rodnans skin score in the assessment of diffuse systemic sclerosis patients: a cross-sectional study

Abstract Background The reproducibility and reliability of the modified Rodnan's Skin Score (mRSS) are debated due to investigator-related subjectivity. Here, we evaluate if durometry correlates with mRSS in patients with diffuse systemic sclerosis (SSc). Methods This cross-sectional study was conducted from December 2018 to June 2019, including 58 diffuse SSc patients. Two certified researchers, blind to each other's scores, performed the mRSS, followed by durometry at 17 predefined skin sites. For durometry and mRSS, individual scores per skin site were registered. Durometry and mRSS results measured by each researcher, as well as scores from different researchers, were compared. Skin thickness measurements from forearm skin biopsies were available in a subset of the patients, for comparisons. Statistical analyses included Cohen's Kappa Coefficient, Intraclass Correlation Coefficient, Kendall's Coefficient and Spearman's test. Results Mean (standard deviation, SD) patient age was 44.8 (12.9) years, and 88% were female. Inter-rater agreement varied from 0.88 to 0.99 (Intraclass correlation coefficient) for durometry, and 0.54 to 0.79 (Cohen's Kappa coefficient) for mRSS, according to the specific evaluated sites. When data were compared with skin thickness assessed in forearm biopsies, durometry correlated better with skin thickness than mRSS. Conclusion Durometry may be considered as an alternative method to quantify skin involvement in patients with diffuse SSc. The strong inter-rater agreement suggests that the method may be useful for the assessment of patients by multiple researchers, as in clinical trials.(AU)

Dermatoses in parkinsonism: the importance of multidisciplinary follow-up

Summary Parkinsonism is characterized by bradykinesia with rigidity and/or resting tremor, in addition to non-motor symptoms, which include dermatological manifestations. The objective of this study is to evaluate the main dermatoses in patients with parkinsonism found at the Philanthropic Association of Curitiba - PR. A cross-sectional descriptive study was carried out with the application of a questionnaire and dermatological evaluation of the patients. The sample consisted of 386 patients and was composed mainly by men (55.4%), between 60-74 years old (51.6%), with complete primary education (45.3%), disease diagnosis time between 5-10 years (35%) and in use of medication (96.6%). The most prevalent dermatoses were pigmented nevus (36.3%), warts (25.1%), actinic keratosis (22%), seborrheic keratosis (21.5%), seborrheic dermatitis (20.5%), and rosacea (19.2%). Among the 13 cases (3.4%) of malignant cutaneous neoplasms confirmed by biopsy, 2 were melanomas. Regarding patients' sex, there was a higher prevalence of inflammatory dermatoses (OR 1.64, 95% CI 1.08-2.51, p = 0.025) and benign cutaneous neoplasms (OR 1.77, 95% CI 1.16-2.69, p = 0.01) in men. As to age, patients aged between 60-74 years had more pre-malignant skin lesions (OR 2.60, 95% CI 1.05-6.44, p <0.001) and seborrheic keratosis (OR 2.52, 95% CI 1.02-6.25, p = 0.001) and, in those older than 75 years, actinic keratosis was more frequent (OR 5.43, 95% CI 2.17-13.6, p <0.001). The results of the study show that it is fundamental to dermatologically evaluate and monitor these patients, aiming at diagnosis and early treatment of lesions, especially of skin cancer.

RESUMO Parkinsonismo é caracterizado por bradicinesia e/ou tremor de repouso, além de sintomas não motores, entre os quais se destacam as manifestações dermatológicas. O objetivo desse trabalho é conhecer as principais dermatoses em pacientes portadores de parkinsonismo atendidos em uma associação filantrópica de Curitiba/PR. Foi realizado um estudo descritivo transversal com aplicação de questionário e avaliação dermatológica dos pacientes. A amostra estudada consistiu de 386 pacientes e foi composta principalmente por homens brancos (55,4%), entre 60-74 anos (51,6%), ensino fundamental completo (45,3%), tempo de diagnóstico da doença entre 5-10 anos (35%) e em uso de medicação (96,6%). As dermatoses mais encontradas na inspeção dermatológica foram manchas pigmentadas (36,3%), verrugas (25,1%), ceratose actínica (22%), ceratose seborreica (21,5%), dermatite seborreica (20,5%) e rosácea (19,2%). Entre os 11 casos (2,8%) de neoplasias cutâneas malignas confirmados por biópsia, dois eram melanomas. Em relação ao sexo, houve prevalência em homens de dermatoses inflamatórias (OR 1,64, IC 95% 1,08-2,51; p=0,025) e neoplasias cutâneas benignas (OR 1,77, IC 95% 1,16-2,69; p=0,01). Quanto à idade, pacientes entre 60-74 anos apresentaram mais lesões cutâneas pré-malignas (OR 2,60, IC 95% 1,05-6,44; p<0,001) e a ceratose seborreica (OR 2,52, IC 95% 1,02-6,25; p=0,001); naqueles acima de 75 anos foi mais frequente a ceratose actínica (OR 5,43, IC 95% 2,17-13,6; p<0,001). Os resultados encontrados no estudo evidenciam que são fundamentais a avaliação e o monitoramento dermatológico desses pacientes, visando diagnóstico e tratamento precoce das lesões, em especial do câncer de pele.

Clinical, dermoscopic, and histologic aspects of two cases of cutaneous focal mucinosis

Abstract: Cutaneous mucinoses are a complex and diverse group of connective tissue disorders characterized by the accumulation of mucin and/or glycosaminoglycan in the skin and adnexa. Cutaneous focal mucinosis appears as a solitary, asymptomatic, skin-colored to white papule, nodule, or plaque located anywhere on the body or in the oral cavity. It presents mainly in adults and is characterized on histopathology by mucin throughout the upper and mid dermis. We describe the dermoscopy of two cases of cutaneous focal mucinosis. Both lesions presented a nonspecific homogenous whitish pattern; the first case also exhibited a sharply demarcated yellow border.

Case for diagnosis. Suppurative nodule or something deeper?

Abstract: The authors report the case of a 62-year-old man with a history of total left hip arthroplasty nine years previously presenting with a large infiltrated plaque on the posterior area of the left thigh with three months of evolution without systemic symptoms or elevated inflammatory markers. Computed tomography of the left lower limb revealed a 12-centimeter linear extension of the lesion to the posterior part of the left proximal femur. Prosthesis joint infection, although rare, is a surgical complication to be taken into account, even if the surgery was performed many years before.

Juvenile xanthogranuloma: a case report / Xantogranuloma juvenil: um caso clínico

ABSTRACT Objective: To report a rate case of Juvenile xanthogranuloma in a newborn infant. Case description: We present the case of a 31-week preterm newborn with multiple skin lesions whose clinical, histological and immunohistochemical findings allowed the diagnosis of juvenile xanthogranuloma. Currently, the patient has nine months-old, and there is no aggravation of the skin lesions or evidence of extra-cutaneous involvement, particularly ophthalmic. Comments: Juvenile xanthogranuloma is a rare and benign condition, included in the vast group of non-Langerhans histiocytosis. It typically occurs in the pediatric age and may have a neonatal presentation. It affects predominantly the skin, in the form of papules or yellow and/or erythematous nodules and could be asymptomatic, multiple or solitary. Extra-cutaneous involvement, is more common in toddlers and when multiple lesions are present. The eye is the most affected site. We highlight this clinical case by its presentation in the neonatal period and in the form of multiple lesions, which bestows an increased risk of extra-cutaneous involvement, although this has not yet been verified.

RESUMO Objetivo: Descrever um caso raro de xantogranuloma juvenil em recém-nascido. Descrição do caso: Apresentamos o caso de um recém-nascido pré-termo de 31 semanas com múltiplas lesões cutâneas cuja clínica, histologia e imuno-histoquímica permitiram o diagnóstico de xantogranuloma juvenil. Atualmente, com nove meses de idade, não apresenta agravamento das lesões nem evidência de envolvimento extracutâneo, nomeadamente oftálmico. Comentários: O xantogranuloma juvenil é uma patologia rara e benigna, pertencente ao vasto grupo das histiocitoses não Langerhans. Surge tipicamente em idade pediátrica, podendo ter apresentação neonatal. O envolvimento é predominantemente cutâneo sob a forma de pápulas ou nódulos de coloração amarela e/ou eritematosos, assintomáticos, solitários ou múltiplos. O envolvimento extracutâneo é mais frequente em crianças com menos de dois anos e com múltiplas lesões, sendo o olho o local mais afetado. Destacamos este caso clínico pela apresentação no período neonatal e sob a forma de múltiplas lesões, o que lhe confere risco acrescido de envolvimento extracutâneo, sem que, no entanto, tal se tenha verificado.

Comparação do Escore de Rodnan modificado e durômetro em pacientes com esclerose sistêmica difusa / Comparison of the modified Rodnan skin score and durometer in patients with diffuse systemic sclerosis

esclerose sistêmica é uma enfermidade autoimune, causadora de danos vasculares e fibroses. É dentre as doenças de sistema conjuntivo, bem conhecida, devido à alta mortalidade, principalmente pelas causas pulmonares e cardíacas. Para a avaliação do tecido cutâneo de portadores de esclerose sistêmica é utilizado o Escore de Rodnan Modificado, que consiste no pregueamento da pele, porém esta avaliação pode ser subjetiva, devido às limitações na mensuração do escore, tanto pela variabilidade do profissional, quanto pela percepção na aferição do procedimento. Na busca de uma forma de avaliação embasada em evidências científicas, propôs-se este estudo para subsidiar a aferição objetiva do tecido cutâneo. O objetivo do estudo foi correlacionar os Escores de Rodnan Modificados e as medidas do aparelho durômetro, obtidos por dois pesquisadores distintos, em pacientes com esclerose sistêmica difusa. Trata-se de um estudo analítico e transversal, realizado com pacientes maiores de 16 anos, de ambos os sexos. A amostra desta pesquisa foi constituída por 58 pacientes, com maior predominância entre pacientes com cor da pele branca. Houve correlação discretamente moderada e moderada entre as avaliações das medidas obtidas com o Escore de Rodnan Modificado e também com o aparelho durômetro realizadas pelos pesquisadores 1 e 2. A concordância entre os pesquisadores foi avaliada com Coeficiente de Kappa para Escore de Rodnan Modificado e Coeficiente de Correlação Interclasse para o aparelho durômetro, com melhores resultados para as medidas obtidas com este aparelho. Houve também forte correlação positiva entre o escore de Rodnan modificado, média durômetro total e espessura da derme. Portanto, concluí-se que o aparelho durômetro poderá ser utilizado como método de avaliação do tecido cutâneo em pacientes com esclerose sistêmica difusa. Além disso, é um aparelho de fácil manuseio, o que possibilita os demais integrantes da equipe de saúde realizarem as medidas

Systemic sclerosis is an autoimmune disease that causes vascular damage and fibrosis. It belongs to the group of connective tissue diseases and is well known because of the high mortality associated with it, especially as a consequence of lung and heart problems. The modified Rodnan skin score is used to evaluate the skin tissue of people with systemic sclerosis. It consists of assessing skin wrinkling, but it can be subjective because of the limitations in the process of obtaining the score, both because of the variability of the professionals who perform the procedure and the perception during the measurement. The present study was proposed to provide resources to objectively measure skin tissue, as an attempt to design an evaluation form based on scientific evidence. Its objective was to correlate modified Rodnan skin scores and measures obtained with durometers collected by two different researchers in patients with diffuse systemic sclerosis. It is an analytical and cross-sectional study, carried out with patients at least 16 years old, of both genders. The sample was made up of 58 patients, with a predominance of people with white skin. There were discreetly moderate and moderate correlations between the evaluations of the measurements obtained with the modified Rodnan score and the durometer equipment carried out by researchers 1 and 2. Agreement between the researchers was assessed by using the kappa coefficient for the modified Rodnan skin score and the interclass correlation coefficient for the durometer equipment, with better results for the measurements collected with the latter method. There was a strong positive correlation between the modified Rodnan skin score, the total average obtained with the durometer, and dermis thickness. It was concluded that durometers can be used as a method to evaluate the skin tissue in patients with diffuse systemic sclerosis.

Aplasia cutis congenita: clinical analysis of 258 cases reported in China / 中华围产医学杂志

Objective To summarize the pathogenesis,diagnosis and treatment of aplasia cutis congenita (ACC) in China.Methods We reviewed and summarized all published ACC cases in China in the past four decades from China National Knowledge Internet(CNKI),Wan-Fang Medical Database and VIP database.Results Totally,258 cases were included,consisting of 144 males,95 females and 19 of unknown gender.Fifteen cases reported family history,16 had maternal morbidity during pregnancy,17 exposed to maternal medication or toxic material.Skin lesions of ACC occurred on the scalp (39 cases,15.1％),trunk (8 cases,3.1％) or limbs (107 cases,41.5％) and sometimes were manifested as multiples skin defects (104 cases,40.3％).Eighty-nine cases (38.4％) were presented with isolated skin defect,and 169 (61.6％) were complicated by other abnormalities or congenital defects.Totally,235(91.1％) cases were treated conservatively,15 cases with dural defect,skull defect or defect area ＞ 10％ underwent dermatoplasty,and the other eight cases refused any treatment.Among the 248 cases being followed up,233 (93.95％) healed after treatment for one week to four months,three had scar contracture,four developed joint contracture,and eight (3.2％) died of hemorrhage or infection.Conclusions ACC is a congenital skin defect which might involve skin,bone and multiple parts of the body,often complicated with other abnormalities.Superficial and small skin defect maybe managed conservatively,while for patients with bone exposure or defect,large area skin defect,surgical management is recommended.Appropriate management can ensure good outcomes in most cases.

Lupus erythematosus tumidus in childhood treated with antimalarials / Lupus eritematoso tumidus en la infancia tratado con antimalárico

Abstract Lupus erythematosus tumidus is a rare dermatosis. It is considered a subtype of chronic cutaneous lupus erythematosus of uncertain pathogenesis, favorable prognosis and rare association with systemic lupus erythematosus. Clinically, it manifests as urticarial-like plaques in photo exposed areas, mainly affecting adults, being extremely rare in pediatric age. Herein, we present two cases of six and nine-year-old male patients with clinical and histological characteristics typical of lupus erythematosus tumidus and poor response to first-line treatment (topical, intralesional steroids and topical calcineurin inhibitors); therefore, it was decided to start systemic therapy with antimalarials, obtaining a very good response.

Resumen El lupus eritematoso tumidus es una dermatosis poco frecuente. Es considerada una variante del lupus eritematoso cutáneo crónico, de patogénesis incierta, pronóstico favorable y rara asociación con lupus eritematoso sistémico. Clínicamente, se manifiesta como placas de aspecto urticarial en zonas fotoexpuestas, que principalmente afectan a los adultos, siendo extremadamente rara en edad pediátrica. A continuación presentamos dos casos de pacientes de sexo masculino de seis y nueve años, con características clínicas e histológicas típicas de lupus eritematoso tumidus y poca respuesta al tratamiento de primera línea (esteroides tópicos, intralesionales e inhibidores de calcineurina tópica), por lo que se decidió iniciar manejo sistémico con antimalárico, obteniendo muy buena respuesta terapéutica.

Oral pigmentations in Laugier-Hunziker syndrome: a case report and review of diagnostic criteria / Pigmentações orais na síndrome de Laugier-Hunziker: relato de caso e revisão dos critérios de diagnóstico

ABSTRACT Laugier-Hunziker syndrome (LHS) is a rare mucocutaneous disorder, of unknown etiology, characterized by multiple hyperpigmented macules, dispersed mostly on the oral mucosa, occasionally associated with longitudinal ridging of the nails. The diagnosis requires exclusion of other conditions, such as Addison's disease and Peutz-Jeghers syndrome. We report a case of a 34-year-old male patient, presenting with hyperpigmented macules on the lips, buccal mucosa and palate, as well as mild dark striations on toenails. After careful clinical and laboratorial investigations, the diagnosis of LHS was established. Given the lack of aesthetic complaints and symptoms, no treatment was necessary.

RESUMO A síndrome de Laugier-Hunziker (SLH) é uma rara desordem mucocutânea, de etiologia indeterminada, caracterizada por múltiplas máculas hiperpigmentadas, dispersas principalmente na mucosa oral, por vezes associadas a estrias longitudinais nas unhas. O diagnóstico requer exclusão de condições como doença de Addison e síndrome de Peutz-Jeghers. Descrevemos o caso de um paciente do sexo masculino, 34 anos, com presença de máculas hiperpigmentadas em lábios, mucosa jugal e palato, além de discretas estrias enegrecidas nas unhas dos pés. Após minuciosa investigação clínica e laboratorial, foi estabelecido o diagnóstico de SLH. Dada a ausência de queixas estéticas e sintomatologia, nenhum tratamento foi necessário.

Radical resection and local coverage of hidradenitis suppurativa - acne inversa: analysis of results / Tratamento cirúrgico de hidradenite supurativa - acne inversa: ressecção radical e cobertura local - análise de resultados

ABSTRACT Objective: to evaluate the primary outcome of local complications and late recurrence in patients with hidradenitis suppurativa undergoing radical resection and specific reconstruction. Methods: we conducted a retrospective analysis of the medical records of patients attended by the Plastic Surgery Service of the Clinics Hospital, Medical School, USP, between 2010 and 2016. We included patients who underwent radical resection of hidradenitis suppurativa in advanced stage and reconstruction through primary closure, grafts or flaps. Results: we analyzed 34 lesions in 19 patients, of which 64.5% had local complications, though with 73.5% efficient healing after 12 weeks postoperatively. We observed late recurrence in 47%, but in isolation, 22.2% of the reconstructions with locoregional flaps had recurrence after one year. Conclusion: extensive and radical resection of the disease associated with locoregional flap coverage (pedicled or perforating) has been shown to be the best management in terms of late results.

RESUMO Objetivo: avaliar o desfecho primário de complicações locais e de recidiva tardia em pacientes com diagnóstico de hidradenite supurativa submetidos à ressecção radical e reconstrução específica. Métodos: análise retrospectiva baseada nos prontuários dos pacientes atendidos pelo serviço universitário de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina da USP, entre 2010 a 2016. Foram incluídos apenas pacientes submetidos à ressecções radicais de hidradenite supurativa em grau avançado, submetidos à reconstrução através de fechamento primário, enxertos ou retalhos. Resultados: foram analisadas 34 lesões, das quais 64,5% apresentaram complicações locais, porém com 73,5% de cicatrização eficiente após 12 semanas de pós-operatório. Recidiva tardia foi observada em 47%, porém, isoladamente, 22,2% das lesões reconstruídas com retalhos locorregionais apresentaram recidiva tardia após um ano. Conclusão: a estratégia de ressecção ampla e radical da doença associada à cobertura da ferida com retalho locorregional (pediculado ou perfurante) demonstrou ser o melhor manejo em termos de resultados tardios.
