Carotid Intima and Media Thickness Correlation with Central Blood Pressure Measurements by Tonometric and Oscillometric Methods: A Proof of Concept

Abstract Background The early detection of vascular damage in subclinical stages of hypertensive disease may be the key point in the prevention of cardiovascular outcomes. Objectives to correlate parameters of structural vascular damage (measurement of the carotid intima-media thickness) with parameters of functional vascular damage (central hemodynamic measurements) in pre-hypertensive and hypertensive patients taking up to two classes of anti-hypertensive drugs. Methods This was a cross-sectional descriptive study conducted with a convenience sample of patients attending the Liga de Hipertensão Arterial , a multidisciplinary program for the diagnosis and treatment of systemic hypertension, of the Federal university of Goias. Patients with arrythmia, diabetes, previous cardiovascular or cerebrovascular diseases, and end-stage diseases were excluded. Carotid Doppler test, measurements of peripheral and central blood pressure by applanation tonometry (Sphygmocor®) and oscillometry (Mobil-O-Graph®) were performed. The t-test was used for comparisons and the Pearson correlation test for correlations, considering a p<0.05 statistically significant. Results twenty patients (12 women) were evaluated, mean age 53.8 ± 14.3 years. Higher values of central pulse pressure (42.9±13.9 vs. 34.7±9.6, p=0.01) and pulse wave velocity (PWV) (9.0±1.9 vs. 7.9±1.5, p=0.01) were obtained by applanation tonometry compared with oscillometry. No difference between the methods was observed for the other measures. A significant correlation was found between carotid artery intima-media thickness (CA-IMT) and PWV (r=0.659; p=0.002) by the oscillometric test, but not with applanation tonometry. No correlation was found between central hemodynamic variables and the presence of carotid artery plaques. Conclusion PWV, estimated by oscillometry, was the only central hemodynamic parameter that correlated significantly with CA-IMT in pre-hypertensive and hypertensive patients at low cardiovascular risk.

Tonometric and Oscillometric Methods for Measurement of Central Blood Pressure Parameters: a Comparison in Patients with Borderline Hypertension or Stage 1 Hypertension

Abstract Background Changes in arterial compliance are among the first changes detectable in hypertensive syndrome. Methods with good reproducibility as compared with the gold standard for identifying such changes are desirable in clinical practice. Objectives To compare central pressure measurements and arterial stiffness obtained by two non-invasive methods (tonometry and oscillometry). Methods This was a descriptive, cross-sectional study with a convenience sample of patients with borderline hypertension or stage 1 hypertension. Peripheral and central blood pressure measurements were obtained by tonometry (SphygmoCor®), considered the gold standard, and oscillometry (Mobil O´graph®). Comparisons of results were made by unpaired t-test, and p values < 0.05 were considered statistically significant. Results No difference was found in central pressure measurements obtained by SphygmoCor® (117 x 80.1 mmHg) compared with Mobil O'graph (112 x 81.4 mmHg). Mean augmentation index (AIx) was 26.1% and 21.3%, and mean pulse pressure (PP) amplification 10.7 mmHg and 10.0 mmHg by Sphygmocor® and Mobil O´graph®, respectively (p > 0.05). Mean pressure wave velocity (PWV), 8.4 m/s vs. 7.4 m/s (p = 0.013) and mean central pulse pressure, 37.7 mmmHg and 30.9 mmHg (p = 0.013) were significantly higher by SphygmoCor® than Mobil O´graph®. Conclusion Values of central systolic blood pressure, AIx and pulse pressure amplification obtained by oscillometry were not statistically different compared with tonometry; values of PWV and cPP, however, were underestimated by oscillometry.

Raça e obesidade na população feminina negra: uma revisão de escopo / Race and obesity in the black female population: a scoping review

Resumo Cerca de 40% da população mundial está acima do peso, sendo a obesidade mais frequente nos estratos com menores rendimentos e tempo de estudo. A relação entre ganho de peso e fatores sociodemográficos é bem documentada, mas poucos pesquisadores buscam associar obesidade com raça/cor. Desta forma, este artigo visa mapear, na literatura científica, a extensão, o alcance e a natureza da relação entre obesidade e raça, por meio de revisão de escopo. As fontes informacionais foram os bancos de dados Medical Literature Analysis and Retrieval System Online (Medline), Excerpta Medica Database (Embase), Web of Science, Health InterNetwork Access to Research Initiative (Hinari) e Scopus, além da literatura cinza. Foram encontrados 2.526 artigos, permanecendo 10 documentos após eliminadas as duplicatas e aplicados os critérios de inclusão e exclusão. Existe uma relação complexa entre raça, obesidade, nível socioeconômico e gênero, cuja especificidade se dá em função do contexto sócio-histórico. As possíveis explicações para as disparidades raciais na obesidade residem nos efeitos fisiológicos, psicológicos e culturais do estresse devido à discriminação racial. Novos estudos devem ser realizados considerando as diferenças regionais, pois a desigualdade racial, embora aconteça em todos os lugares, assume diferentes formatos.

Abstract About 40% of the world's population is overweight. Obesity is most prevalent among social strata with lower income and education. Although the association between sociodemographic factors and weight gain is well documented, few researchers associated obesity with race/color. This article aims to map the extent, scope, and nature of the association between obesity and race in the scientific literature by conducting a scoping review. Data sources were the Literature Analysis and Retrieval System Online (Medline), Excerpta Medica Database (Embase), Web of Science, Health InterNetwork Access to Research Initiative (Hinari), and Scopus databases, as well as the gray literature. In total, 2,526 articles were found. After duplicates were excluded and inclusion and exclusion criteria applied, 10 articles remained. Race, obesity, socioeconomic status, and gender are tied into a complex relationship whose specificity lies on the socio-historical context. Racial disparities in obesity may be explained by physiological, psychological, and cultural effects of stress due to racial discrimination. Although racial inequality happens everywhere, it assumes different forms. Considering that, further studies should approach regional differences.

Conclusión: 2/3 de los óbitos en el primer día de vida podrían haber sido evitados con una atención adecuada a la mujer embarazada, al parto y al NV.

Objective: to calculate mortality rates on the first day of life from 2010 to 2015 in eight Brazilian Federative Units providing better quality information, to assess associated factors and to classify deaths by underlying causes and avoidability. Methods: this was a descriptive study; mortality rates were compared according to maternal and child characteristics; avoidability analysis used the 'Brazilian list of avoidable causes of death'. Results: 21.6% (n=20,791) of all infant deaths occurred on the first day of life; the mortality rate reduced from 2.7 to 2.3 deaths/1,000 live births; rates were higher in live births with low birthweight and preterm births, and among babies born to mothers with no schooling; main causes of death were respiratory distress syndrome (8.9%) and extreme immaturity (5.2%); 66.3% of causes of death were avoidable. Conclusion: 2/3 of deaths on the first day of life could have been avoided with adequate care for women during pregnancy and delivery and adequate care for live births.

Cutaneous leukemic infiltration following varicella - a case of Wolf's isotopic response

Abstract Wolf's isotopic response designates the appearance of two subsequent unrelated dermatoses in the same anatomic location. We report the case of a 51-year-old man with a medical history of chronic lymphocytic leukemia without known extra-hematopoietic involvement. The patient developed a disseminated papulo-vesiculous eruption, diagnosed as varicella. Few days after recovering, an erythematous and violaceous papular dermatosis with histopathological examination compatible with leukemic infiltration appeared on the scars of previous herpetic lesions. Complete remission was obtained under systemic corticotherapy, without cutaneous recurrence or blastic transformation. Wolf's isotopic response is attributed to a localized immunologic imbalance following a certain stimulus. In this patient, herpetic infection acted as a local spur for inaugural cutaneous leukemic infiltration, with no impact on the prognosis for the underlying disease.

Conflito de Interesses em Eventos de Educação Médica Continuada (EMC): o que Palestrantes e Ouvintes Consideram Importante que Seja Declarado? / Conflicts of Interest at Continuing Medical Education Events: What do Speakers and Listeners Believe must be Declared?

RESUMO Introdução As companhias farmacêuticas representam a principal fonte de inovações terapêuticas na medicina, daí têm participação importante em eventos de educação médica continuada (EMC). Objetivos Conhecer as concepções de médicos (palestrantes ou ouvintes) acerca do significado dos conflitos de interesses em eventos de EMC e que tipo de relação deveria ser declarado. Metodologia Médicos que atuam numa universidade brasileira responderam a um questionário com perguntas abertas e fechadas. Os dados qualitativos foram analisados de acordo com uma análise de conteúdos, e os quantitativos submetidos a análise estatística apropriada. Resultados Setenta e seis médicos responderam ao questionário; 55,3% consideram o conflito de interesses como uma situação, enquanto 44,7% o consideram um comportamento. Além do financiamento de pesquisa relacionada ao tema da palestra, mais da metade dos participantes apontou outros seis tipos de relacionamento indústria/palestrante cuja declaração é desejável. Cinquenta por cento dos palestrantes e 18% dos ouvintes acreditam estar bem preparados para lidar com as indústrias farmacêuticas. Considerações finais Escolas médicas, Conselho Federal de Medicina e Associação Médica Brasileira deveriam trabalhar para aprimorar a compreensão dos médicos acerca do tema e criar regras claras sobre o que deveria ser declarado.

ABSTRACT Introduction Pharmaceutical companies are the main source of therapeutic innovations in medicine, thus playing an important role in continuing medical education (CME). Objectives To study physicians’thoughts on conflicts of interests at CME events. Methodology Physiciansworkingat a Brazilian public university responded to a questionnaire featuring open and closed questions, with qualitative data studied according to a content analysis and quantitative data subjected to a proper statistical analysis. Results 76 physicians answered the questionnaire, with 55.3% considering conflicts of interests to constitute‘situations’ and 44.7% seeingthem as a form of‘behavior’. Besides financial support for research related to the presentations, the majority of participants pointed to six other kinds of industry/speaker relationship in which a declaration should be mandatory. Only 50% of speakers and 18% of listeners feel prepared to deal with pharmaceutical companies’ issues. Final considerations Medical schools and medical representative entities should work toward improving physicians’ understanding of this issue and creating objective rules on what must be declared.

Há lugar para o uso de probióticos na saúde bucal? / Is there a place for probiotics in oral health? Systematic review

Objetivo: revisar os efeitos dos probióticos na profilaxia e tratamento de doenças da cavidade oral. Material e métodos: buscou-se artigos no Medline, Lilacs e SciELO com as estratégias de busca: treatment and "oral health" and probiotics; probiotics and "oral health"; probiotics and "oral cavity"; prevention and "oral health" and probiotics; probiotics and "mouth diseases". Critérios de inclusão: pesquisas em humanos, em inglês, português e espanhol, e foco nos efeitos dos probióticos na saúde bucal. Critérios de exclusão: estudos em animais, ou publicados em outros idiomas, e não relacionados ao benefício dos probióticos na cavidade oral. Resultados: foram incluídos 14 artigos (revisão, ensaio clínico e caso-controle), publicados na Alemanha, Brasil, Cuba, Dinamarca, Índia, Inglaterra e Peru, todos de alta qualidade metodológica. O uso de probióticos parece favorecer o equilíbrio da microflora bucal e reduzir a incidência de cáries, gengivites, halitoses, candidíase oral e periodontites. Apenas dois artigos declararam conflito de interesse, riscos e danos do uso de probióticos. Conclusão: dada a importância dos probióticos e seu potencial promissor, mais estudos isentos de interesses comerciais são necessários para avaliar o custo/efetividade e segurança dos probióticos na profilaxia, e tratamento de doenças bucais antes que profissionais da saúde e governos possam recomendá-los.

Objective: review the effects of probiotics in the prevention and treatment of oral cavity diseases. Materials and methods: the Medline, Lilacs, and SciELO databases were screened using the following strategies: treatment and "oral health" and probiotics; probiotics and "oral health"; probiotics and "oral cavity"; prevention and "oral health" and probiotics; probiotics and "mouth diseases". Inclusion criteria: studies performed in humans in English, Portuguese and Spanish, with focus on probiotics' effects on oral health. Exclusion criteria: studies performed in animals, published in different languages, and without direct relationship with the benefi ts of using probiotics for oral health. Results: 14 articles were included (review, clinical trial and case control), published between 2008 and 2013 in Germany, Brazil, Cuba, Denmark, India, England and Peru. Articles included reached high methodological quality. It seems that the use of probiotics enhance balance of the oral microflora, which reduces the incidence of caries, gingivitis, halitosis, periodontitis, and oral candidiasis. Only two articles superficially reported conflict of interests, risks, and damages from probiotics usage. Conclusion: given the importance and potential of probiotics, further studies free of commercial interests are needed to evaluate their cost-effectiveness and safety in the prevention and treatment of oral diseases, before professionals and government programs may recommend their usage.

A doença celíaca como causa de infertilidade feminina: uma revisão sistemática / Celiac disease as a cause of women infertility: a systematic review

A doença celíaca (DC) apresenta, além de alterações gastrintestinais, manifestações atípicas, como infertilidade. O trabalho objetivou demonstrar a relação entre DC e infertilidade feminina, bem como elucidar a importância de sua triagem, por via sorológica, em mulheres com infertilidade de causa desconhecida. Revisão sistemática de 40 artigos publicados entre 1999 e 2014, por meio de buscas sistemáticas utilizando as bases de dados MEDLINE (via PUBMED), LILACS e SciELO. A prevalência de DC no Brasil foi de um para 681 em grupos presumivelmente sadios e 1 para 293 em adultos e crianças sem queixas gastrintestinais. Foi descrito relação entre anticorpos presentes na DC e desordens do aparelho reprodutor feminino, determinando supressão de fatores de crescimento, alterações das funções secretoras da placenta, dano trofoblástico e apoptose tecidual. Além disso, a atrofia das vilosidades na DC promove deficiência nutricional, determinando oligomenorreia, metrorragia e dismenorreia. No recém-nascido, observou-se prematuridade, pré-eclâmpsia e indivíduos pequenos para idade gestacional. A grande relevância do diagnóstico se dá pelo fato de o tratamento poder prevenir danos tanto para o feto quanto para a mãe. Existe relação entre DC e infertilidade e a triagem sorológica em mulheres com infertilidade de causa desconhecida está indicada.(AU)

The celiac disease (DC) presents gastrintestinal alterations, as well as unusual signs such as infertility. The objective of this review is to demonstrate the relation between DC and woman infertility, and show the importance of its screening through serological methods in women with unexplained infertility. Systematic review of 40 published articles between 1999 and 2014, through systematic search using MEDLINE (via PUBMED), LILACS e SciELO databases. The prevalence of DC in Brazil was from one to 681 in healthy groups and from one to 293 in adults and children without gastrointestinal complaints. It was described a relation between antibodies present in DC and women reproductive system disorders, determining suppression of growth factors, alterations in the secretory placenta functions, trophoblastic damage and tissue apoptosis. Besides that, the atrophy of intestinal villus in DC promotes nutritional deficiency, determining oligomenorrhea, metrorrhagia e dysmenorrhea. In newborns, it was observed prematurity, pre-eclampsia and small individuals for gestational age. The biggest relevance of the diagnosis is due to the fact of the treatment to prevent damage for the fetus as well as the mother. There is a relation between DC and infertility so, the sorological screening in women with unexplained infertility is recommended.(AU)

Porokeratosis ptychotropica of the scrotum: dermoscopic evaluation of an atypical presentation

Porokeratosis ptychotropica is a rare variant of porokeratosis that is classically located on the gluteal and perianal regions, seldom extending to the genitalia. The authors report an atypical presentation of porokeratosis ptychotropica and discuss the use of dermoscopy in evaluating this dermatosis. Dermoscopic findings, although not specific to this variant of porokeratosis, are helpful in the differential diagnosis of other genital disorders. Histopathology, through the visualization of multiple cornoid lamellae, prevails as the gold standard for the definite diagnosis of porokeratosis ptychotropica.

Computed Tomograpy Venography diagnosis of iliocaval venous obstruction in advanced chronic venous insufficiency / Diagnóstico angiotomográfico da obstrução venosa ilíaco-cava na Insuficiência Venosa Crônica avançada

Objective: Iliocaval obstruction is associated with venous hypertension symptoms and may predispose to deep venous thrombosis (DVT). Ultrasonography may fail to achieve noninvasive diagnosis of these obstructions. The possibility of using Computed Tomography Venography (CTV) for these diagnoses is under investigation. Methods: Patients with CVI graded at CEAP clinical classes 3 to 6 and previous treatment failure underwent evaluation with CTV. Percentage obstruction was rated by two independent examiners. Obstruction prevalence and its associations with risk factors and CEAP classification were analyzed. Results: A total of 112 limbs were prospectively evaluated. Mean patient age was 55.8 years and 75.4% were women. Obstructions involved the left lower limb in 71.8% of cases and 35.8% of patients reported a medical history of deep venous thrombosis. Overall, 57.1% of imaging studies demonstrated venous obstruction of at least 50% and 10.7% showed obstruction of >80%. The only risk factor that was found to be independently associated with a significantly higher incidence of >50% venous obstruction was a medical history of DVT (p=0.035) (Fisher's exact test). There was a positive relationship between clinical classification (CEAP) and degree of venous obstruction in the limbs studied (Chi-square test for linear trend; p=0.011). Conclusion: Patients with advanced CVI are often affected by obstructions in the iliocaval venous territory and CTV is able to diagnose the degree of obstruction. There is a positive association between degree of obstruction and both previous history of DVT and severity of symptoms of CVI. .

Objetivo: A obstrução ilíaco-cava é associada a sintomas de hipertensão venosa e é um fator de risco para a trombose venosa profunda (TVP). A ultrassonografia pode falhar em seu diagnóstico. Não existe método de "sreening" bem estabelecido. A capacidade da Angiotomografia em realizar esse diagnóstico vem sendo investigada. Método: Pacientes portadores de IVC avançada e com falha no tratamento clínico foram submetidos à Angiotomografia. As imagens foram classificadas quanto ao grau de obstrução por dois investigadores independentes. Foram avaliados a prevalência e o grau de obstrução, e a sua relação com dados demográficos, fatores de risco e sintomas clínicos (CEAP). Resultados: Foram avaliados 112 membros. A idade média dos pacientes foi de 55,8 anos e 75,4% eram mulheres. A obstrução acometia o membro inferior esquerdo em 71,8% e havia história de TVP em 35,8% destes. Em 57,1% dos membros, havia obstrução > 50% e, em 10,7%, a obstrução era > 80%. A história de TVP foi o único fator demográfico com associação positiva com o grau de obstrução (p = 0,035) (teste Exato de Fisher). Houve associação positiva entre a classificação clínica (CEAP) e o grau de obstrução venosa (Teste Qui-quadrado para tendência linear; p=0,011). Conclusão: Pacientes portadores de IVC avançada são frequentemente acometidos por obstrução venosa ilíaco-cava e a Angiotomografia é capaz de identificar o grau dessa obstrução. Existe uma relação positiva entre o grau de obstrução e a classificação clínica, e a história de TVP .

Case for diagnosis

Cutaneous involvement associated to multiple myeloma varies from 5 to 10% of cases and is infrequently recognized. Cutaneous metastatic plasmacitomas are rare. We present the case of a 72-year-old man with multiple myeloma in complete remission since 2 years ago with cutaneous tumors on the trunk and face. A cutaneous biopsy was consistent with plasmacytoma. The patient was treated with melphalan, prednisolone and radiotherapy. Despite optimal therapeutic response of the lesions, the disease progressed, with the appearance of new extra-cutaneous plasmocytomas. The cutaneous metastatic plasmocytomas were the first sign of progression of the disease.

Blastic plasmacytoid dendritic cell neoplasm / Neoplasia blastica de celulas dendriticas plasmocitoides

Blastic plasmacytoid dendritic cell neoplasm is a rare and aggressive hematodermic neoplasia with frequent cutaneous involvement and leukemic dissemination. We report the case of a 76-year-old man with a 2 month history of violaceous nodules and a tumor with stony consistency, located on the head, and mandibular, cervical and supraclavicular lymphadenopathies. Multiple thoracic and abdominal adenopathies were identified on computerized tomography. Flow cytometry analysis of the skin, lymph node and bone marrow biopsies demonstrated the presence of plasmocytoid dendritic cell neoplastic precursor cells (CD4+, CD45+, CD56+ and CD123+ phenotype). After initial clinical and laboratorial complete remission with chemotherapy, the patient died due to relapse of the disease associated with the appearance of a cervical mass with medullary compromise.

A neoplasia blástica de células dendríticas plasmocitóides é uma neoplasia hematodérmica rara, agressiva, com frequente envolvimento cutâneo e disseminação leucêmica. Relatamos o caso de um homem de 76 anos com quadro clínico com 2 meses de evolução caracterizado por nódulos e tumor de tonalidade violácea, de consistência pétrea, localizados na cabeça, e linfadenopatias mandibular, cervicais e supraclaviculares. Identificaram-se múltiplas adenopatias torácicas e abdominais em tomografia computorizada. A análise por citometria de fluxo de biópsias cutânea, ganglionar e óssea demonstrou a presença de precursores neoplásicos das células dendríticas plasmocitóides (fenótipo CD4+, CD45+, CD56+ e CD123+). Após remissão clínica e laboratorial completa inicial com quimioterapia, veio a falecer por recaída da doença associada ao aparecimento de massa cervical com compromisso medular.

Cutaneous leiomyomatosis in a mother and daughter / Leiomiomatose cutanea em mae e filha

A 34-year-old woman with no known medical history was evaluated for multiple painful brown nodules and papules on the anterior aspect of the trunk. She mentioned a history of similar cutaneous findings on her mother. Biopsies of three lesions revealed piloleiomyomata. Renal and adrenal ultrasound revealed an isolated simple cortical cyst, and pelvic and endovaginal ultrasound revealed two uterine myomata. The clinical diagnosis of hereditary leiomyomatosis and renal cell cancer was corroborated by the identification of a heterozygous variant on exon 5 of the fumarate hydratase gene (c.578C>T p.T193I). Identification of the tumor piloleiomyoma should alert the dermatologist to this rare genodermatosis, which is associated with an increased risk of renal cell tumors, demanding multidisciplinary follow-up, and personal and family counseling.

Uma mulher de 34 anos sem antecedentes patológicos conhecidos foi avaliada por apresentar múltiplos nódulos e pápulas castanhos, dolorosos, na face anterior do tronco. Referia história de achados cutâneos semelhantes na sua mãe. As biópsias de três lesões revelaram piloleiomiomas. As ecografias renal e suprarenal identificaram apenas cisto renal cortical simples, e as ecografias endovaginal e pélvica, dois miomas uterinos. O diagnóstico clínico de leiomiomatose herediária e câncer de células renais foi corroborado pela identificação de variante heterozigota no exon 5 do gene da Fumarato hidratase (c.578C>T p.T193I). O piloleimomioma é um tumor cuja identificação deve alertar o dermatologista para esta rara genodermatose, associada a um risco aumentado de tumores de células renais, exigindo seguimento multidisciplinar e aconselhamento pessoal e familiar.

Exacerbation of recalcitrant cutaneous sarcoidosis with adalimumab - a paradoxical effect? A case report / Agravamento de lesoes refratarias de sarcoidose cutanea com adalimumab- um efeito paradoxal? Relato de um caso

The paradoxical adverse effects of tumor necrosis factor-alpha (TNF-alpha) antagonists have been described frequently as a result of the widespread use of these drugs. Among the TNF-alpha blocking agents, few reports exist relating the use of adalimumab in cutaneous sarcoidosis, although all of them show good results. More recently, sarcoidosis onsets have been reported with various TNF-alpha inhibitors. The current case is, to our knowledge, the first to describe the exacerbation of cutaneous lesions of sarcoidosis treated with adalimumab.

Os efeitos paradoxais dos anti-TNF-alpha têm sido cada vez mais descritos com a utilização mais ampla dessas drogas. Entre os TNF-alpha, registam-se poucos casos com a utilização de adalimumab no tratamento da sarcoidose cutânea, sendo que todos eles apresentam bons resultados. Têm sido descritos, mais recentemente, casos de sarcoidose induzidos por vários anti-TNF-alpha. O presente caso é, até à data, o primeiro a descrever a exacerbação de lesões cutâneas de sarcoidose tratadas com adalimumab.

Using 80% trichloroacetic acid in the treatment of ingrown toenails / Acido Tricloroacetico a 80% no tratamento da onicocriptose

BACKGROUND: Ingrown nails are a very common problem. There are different stages of disease and diverse therapeutic options. Phenol and sodium hydroxide are commonly used agents for chemical matricectomy but both frequently entail excessive healing times. OBJECTIVE: This prospective study aimed mainly to evaluate the efficacy of partial nail avulsion and selective chemical cauterization of the matrix using 80% TCA in the treatment of the ingrowing nail. METHODS: One-hundred-and-thirty-three patients with 197 ingrown toenails were included in this study. Preoperatively, we tried to find predisposing factors to the disease. In the postoperative period, patients were evaluated for potential complications at days 3, 30, 180, 270 and 360. Pain was measured before surgery, as well as 24 hours and 72 hours after surgery. RESULTS: There were only 3 cases (out of 197) of ingrown nail recurrence. Preoperatively, we found the presence of drainage in 82% of patients, which, following the first visit after surgery, was reduced to 19%. Persistent granulation tissue was found in 3% of the patients (versus 75% prior to surgery). The most frequent predisposing factors for the ingrown nail were excessive trimming of the lateral nail plate (63%), plantar hyperhidrosis (58%) and heavy nail folds (39%). Pain was substantially reduced after surgery. CONCLUSION: It is assumed that chemical procedures for the ingrown toenail are associated with delayed healing times but our results demonstrated quick recovery. Using 80% TCA for selective matricectomy in the ingrown toenail is an effective, quick and easy method. .

FUNDAMENTO: A unha encravada é uma patologia muito frequente. A doença engloba diferentes estadios existindo diferentes soluções terapêuticas. O fenol e o hidróxido de sódio são largamente utilizados na matricetomia química porém ambos cursam com longos tempos de cura. OBJETIVO: O principal objectivo deste estudo prospectivo foi avaliar a eficácia da mactricectomia com ácido tricloroacético a 80% no tratamento da unha encravada. MÉTODOS: Foram incluídos no estudo 133 doentes com 197 unhas encravadas. Factores predisponentes foram avaliados pré-operatoriamente. No período pós-operatório os doentes foram avaliados para potenciais complicações ao dia 3, 30, 180, 270 e 360. A dor foi avaliada antes da cirurgia, 24 horas e 72 horas depois da cirurgia. RESULTADOS: Ocorreram apenas 3 (em 197) casos de recorrência da unha encravada. Antes da cirurgia registou-se exsudação em 82% dos doentes sendo que na primeira visita após a cirurgia este número foi reduzido para 19%. Observou-se ainda tecido de granulação persistente em 3% dos doentes (versus 75% antes da cirurgia). Os factores predisponentes mais frequentemente encontrados para unha encravada foram o corte excessivo da porção lateral da placa ungueal (63%), hiperhidrose plantar (58%) e pregas ungueais espessadas (39%). A dor teve uma redução dramática após a cirurgia. CONCLUSÃO: É assumido que os procedimentos químicos para a unha encravada estão associados com longos tempos de cura mas os nossos resultados mostraram uma rápida recuperação. No tratamento da unha encravada a matricectomia parcial com ácido tricloroacético a 80% é um método rápido, eficaz e de fácil execução. .

Do you know this syndrome? / Voce conhece esta sindrome?

POEMS syndrome is a unique clinical entity, the diagnosis of which is made when polyneuropathy and monoclonal gammopathy occur together, associated with other changes such as organomegaly, endocrinopathy, skin changes and papilledema. Cutaneous manifestations are heterogeneous, with diffuse cutaneous hyperpigmentation, hemangiomas and hypertrichosis occurring more frequently. We report the case of a 65- year-old female patient with this syndrome, diagnosed after 15 years of disabling peripheral neuropathy.

As manifestações cutâneas são heterogéneas, sendo as mais frequentes a hiperpigmentação cutânea difusa, os hemangiomas e a hipertricose. Relata-se o caso de uma doente de 65 anos com essa síndrome diagnosticada após 15 anos de neuropatia periférica.

Esporte na cidade: novos espaços, novos objetos... uma nova paisagem em Vitória (1896-1940) / Sports in the city: new spaces, new objects... a new landscape in Vitória (1896-1940)

Em relação à cidade de Vitória, muito pouco sabemos sobre o desenvolvimento das práticas ligadas ao ócio, ao lazer e ao esporte no início do século XX. Analisamos a capacidade de essas práticas redefinirem os usos do território urbano, produzindo novas formas espaciais e introduzindo novos objetos na paisagem. A investigação se situou entre os anos de 1896 e 1940 e tomou como referência a história de alguns clubes capixabas, registrada em fontes diversas, como revistas, jornais, relatórios e imagens publicadas no período em tela. Concluímos que o movimento que difundiu as práticas de ócio, lazer e esportes em Vitória apresentou dois fatores diretamente relacionados com espaços públicos: por um lado, a criação de espaços e/ou a introdução de objetos na paisagem com vistas a reunir o público em torno do espetáculo esportivo; por outro, o incentivo às atividades ao ar livre (nas praias, nos jardins, nas praças e nos "passeios").

Regarding the city of Vitória (Espírito Santo, Brazil), we know very little about the development of practices related to leisure, recreation and sport in the early twentieth century. We analyzed how these practices can redefine the uses of urban territory, producing new spatial forms and introducing new objects in the landscape. The investigation covered the period from 1896 to 1937 and took as a reference the history of some clubs in the state, recorded in various sources, including magazines, newspapers, reports and images published in the period under consideration here. We concluded that the movement that spread the practices of leisure, recreation and sports in Vitória presented two factors directly related to public spaces: on the one hand, the designing of spaces and/or the introduction of objects in the landscape in order to gather the people around the sporting spectacle; on the other hand, the stimulus to the outdoor activities (on beaches, in gardens, in squares and on sidewalks).

Checklist das Cryptophyceae do estado de São Paulo, Brasil / Checklist of Cryptophyceae from São Paulo State, Brazil

Usando como base de informações a monografia sobre o grupo publicada pelo projeto Flora Ficológica do Estado de São Paulo (Programa BIOTA), o acervo depositado no Herbário Científico do Estado de São Paulo "Maria Eneyda P. Kauffmann Fidalgo" (SP), a Lista de Espécies da Flora do Brasil e artigos científicos, dissertações e teses (com descrições e ilustrações) temos: nove gêneros e 39 espécies de criptoficeas, sendo 16 espécies exclusivas para o Estado de São Paulo, todas registradas em ambientes de água doce. A carência de especialistas no Estado de São Paulo e no Brasil, além de problemas de estratégia amostral, necessidade de uso da microscopia eletrônica e ausência de estudos de biologia molecular, são fatores que devem ter subestimado o conhecimento taxonômico de Cryptophyceae no Estado.

Based on the information provided by the monograph on the group published by the project Phycology Flora of São Paulo (BIOTA), the collection deposited in the Scientific Herbarium "Mary P. Eneyda Kauffmann Fidalgo " of the State of São Paulo, the List of Endangered Species of the Flora of Brazil and scientific papers, dissertations and theses (with descriptions and illustrations), there are nine genera and 39 species of cryptophytes, 16 of which are unique species to the State of São Paulo, all recorded in freshwater environments. The lack of specialists in the State of São Paulo and Brazil as well as problems in the sampling strategy, the necessary use of electronic microscopy and the absence of molecular biology studies are factors that must have underestimated the taxonomic knowledge of Cryptophyceae in the state.
