Epidemiological and clinical study of cases of endemic pemphigus foliaceus and pemphigus vulgaris in a reference center in the state of Minas Gerais, Brazil

Abstract Background: Pemphigus constitutes a group of autoimmune bullous diseases. A reduction in the incidence of endemic pemphigus foliaceus and an increase in pemphigus vulgaris has been described, but there are no studies in Minas Gerais that address the subject. Objective: To describe the epidemiological and clinical profile of patients with pemphigus treated at the Dermatology Service of a public University Hospital in the state of Minas Gerais, Brazil. Methods: An observational, descriptive, and cross-sectional study was carried out of cases of endemic pemphigus foliaceus and pemphigus vulgaris, for a period of six months. A questionnaire was filled out with epidemiological and clinical data on the disease. Results: A total of 122 patients were included in the study, 64 with endemic pemphigus foliaceus and 58 with pemphigus vulgaris. When comparing patients with endemic pemphigus foliaceus and those with pemphigus vulgaris, a statistical difference was observed between the median age of initial disease manifestation (p = 0.001), patient occupation (p = 0.010), area of residence (p = 0.000), forests (p = 0.000) and rivers/streams close to the dwelling (p = 0.001) and the number of systemic medications required to control the disease (p = 0.002). When comparing patients with endemic pemphigus foliaceus to those evaluated in a study carried out at the same service in 2008, there was a statistical difference in the area of residence (p = 0.030). Study limitations: The assessed population comes from a tertiary care service that is not a reference for the entire state. Conclusions: Patients with endemic pemphigus foliaceus and pemphigus vulgaris maintain statistically significant differences regarding their main variables in the literature, such as age and area of residence. Historically, there has been a reduction in cases of endemic pemphigus foliaceus and an increase in cases of pemphigus vulgaris in this population.

Different profiles of chemokines, cytokines and cell growth factors in plasma samples from patients with leprosy, leprosy reactions and households contacts

BACKGROUND Leprosy is a highly neglected disease that is considered a serious public health problem in many countries. This illness is characterised by a variety of clinical and histopathological manifestations that are related to the patient immune response. OBJECTIVES This work aimed evaluate the profile of circulating immune mediators in the plasma from patients classified clinically as paucibacillary (PB), multibacillary (MB), households contacts (HHC), type1 leprosy reaction (T1R), type2 leprosy reaction (T2R) and control individuals without medical history of leprosy (CTL). METHODS To assessment of the plasma immune mediators was used multiplex microbeads immunoassay "Luminex". FINDINGS The results showed that patients (PB) had a regulatory-biased profile, while MB revealed a pro-inflammatory trend of highly expressed biomarkers. HHC display conspicuously increased levels in the plasma of the chemokines (CCL2, CCL3, CCL4, CCL5 and CXCL8), pro-inflammatory cytokines (IFN-γ,TNF and IL-1β), modulating cytokines (IL-9 and IL-1Ra) and growth factors (PDGF, G-CSF and IL-2). Interestingly, HHC displayed superior production of IFN-γ as compared to other leprosy groups, indicating a putative protective role for this cytokine during chronic Mycobacterium leprae exposure. MAIN CONCLUSION Further investigations are currently underway to elucidate the potential of these mediators as biomarkers applicable to the diagnosis/prognosis of leprosy and also T1R and T2R leprosy reactions.

Frequency of skin diseases in renal transplant recipients and patients with chronic kidney disease in a tertiary center: a cross-sectional study

ABSTRACT BACKGROUND: The prevalence of chronic kidney disease (CKD) has increased in the recent decades, along with the number of patients in the terminal stages of this disease, requiring transplantation. Some skin disorders are more frequent in patients with CKD and in renal transplant recipients (RTR). OBJECTIVES: To evaluate the frequency of skin diseases in RTR and patients with CKD receiving conservative treatment. DESIGN AND SETTING: This observational cross-sectional study recruited consecutive patients with CKD and RTR from a nephrology clinic at a teaching hospital in Brazil between 2015 and 2020. METHODS: Quantitative, descriptive, and analytical approaches were used. The sample was selected based on convenience sampling. Data were collected from dermatological visits and participants' medical records. RESULTS: Overall, 308 participants were included: 206 RTR (66.9%, median age: 48 years, interquartile range [IQR] 38.0-56.0, 63.6% men) and 102 patients with CKD (33.1%, median age: 61.0 years, IQR 50.0-71.2, 48% men). The frequency of infectious skin diseases (39.3% vs. 21.6% P = 0.002) were higher in RTR than in patients with CKD. Neoplastic skin lesions were present in nine (4.4%) RTR and in only one (1.0%) patient with CKD. Among the RTR, the ratio of basal cell carcinoma to squamous cell carcinoma was 2:1. CONCLUSIONS: This study revealed that an increased frequency of infectious skin diseases may be expected in patients who have undergone kidney transplantation. Among skin cancers, BCC is more frequently observed in RTR, especially in those using azathioprine.

Molecular analysis of the prevalence of Acinetobacter baumannii in hospitals and the surrounding environments: a cross-sectional study

Acinetobacter baumannii is widely recognized in clinical environments due to its infectious capacity, antimicrobial adaptability, and lethality. Analyzing the prevalence of this agent in intra- and extra-hospital environments may reveal target indicators for appropriate management interventions. In this observational cross-sectional study, we evaluated the prevalence of A. baumannii within hospitals with intensive care units and in their external surroundings in a macro-health region of Brazil. Samples of Columba livia (pigeon) droppings from the external environment of four hospitals (n = 40), from floor surfaces (n = 20), and door handles (n = 20) of different hospital wards were collected based on random sampling, all of which were evaluated for the presence of A. baumannii using polymerase chain reactions (PCR). The sensitivity and specificity of the technique was verified after the collected samples were contaminated with clinical samples positive for A. baumannii. We detected a significantly higher A. baumannii prevalence (87.50%, CI = 71.29­100.00) in samples collected within the hospital environment compared with those obtained from the external environment (12.50%, CI = 0.00­28. 71) (p = 0.003). In addition, samples collected from floor surfaces contained bacterial densities (181.3 ± 11.58) that exceeded those in environmental (93.32 ± 1.56) and door handle (142.70 ± 17.14) samples by 94% and 78.71%, respectively. The findings of this study will enhance our understanding of the spatial distribution of A. baumannii and additionally, validate the efficiency of PCR for diagnosis of this infectious agent.

Unlocking the secrets of saliva: the promising potential of salivary biomarkers for evaluating crack use / Desvendando os segredos da saliva: o potencial promissor dos biomarcadores salivares para avaliar o uso de crack

The forthcoming letter will encompass the following highlights: Crack cocaine use involves smoking a highly addictive form of cocaine, which is a significant concern in Brazil, particularly in urban areas. This addiction is linked to various health problems, including cardiovascular issues, sexually transmitted infections (STIs) like AIDS and syphilis, tuberculosis, and a notable increase in mortality, largely due to violent causes. Furthermore, crack cocaine users are particularly vulnerable to dental caries, gingival inflammation, oral mucosa lesions, and xerostomia (AU)

A próxima carta incluirá os seguintes destaques: O uso de crack envolve fumar uma forma altamente viciante da cocaína, o que é uma preocupação significativa no Brasil, especialmente em áreas urbanas. Esta dependência está ligada a vários problemas de saúde, incluindo problemas cardiovasculares, infecções sexualmente transmissíveis (IST), como a AIDS e a sífilis, a tuberculose e um aumento notável da mortalidade, devido, em grande parte, a causas violentas. Além disso, os usuários de crack são particularmente vulneráveis a cáries dentárias, inflamação gengival, lesões na mucosa oral e xerostomia (AU)

Staphylococcus aureus and Enterococcus faecium isolated from pigeon droppings (Columba livia) in the external environment close to hospitals

ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

Das amas de leite às mães órfãs: reflexões sobre o direito à maternidade no Brasil / From wet nurses to orphaned mothers: reflections on the right to maternity in Brazil

Resumo O artigo aborda a retirada compulsória de filhos de mulheres em situação de vulnerabilidade no Brasil. Objetivou-se refletir sobre a violação do direito à maternidade; apresentar os limites impostos, especialmente às mulheres pobres, negras e indígenas e as estratégias de controle sobre sua vida e de seus filhos; e os movimentos de resistência que se contrapõem às segregações. Foram fontes da pesquisa: narrativas de mulheres em situação de vulnerabilidade, de familiares e trabalhadores da saúde; entrevistas com atores estratégicos; análise documental; diários de campo. Evidenciou-se que vulnerabilidades atreladas à criminalização da pobreza e ao preconceito racial têm justificado as separações. A desresponsabilização do Estado e da sociedade quanto à formação de uma rede de apoio às mulheres, a desvalorização de produções não hegemônicas de maternidades e o reforço de uma razão de mundo que produz a violência como ferramenta para exclusão vão conformando limites práticos quanto ao direito à maternidade. Mulheres e seus filhos são desconsiderados em suas singularidades. Os movimentos de resistência mostraram que diálogos intersetoriais são uma alternativa para superar discriminações e vulnerabilidades.

Abstract This article addresses the compulsory seizing of children from vulnerable women in Brazil. Its objectives were: to discuss the violation of the right to maternity; to present the imposed restrictions especially on poor, black and indigenous women; the strategic control over their lives and children, and the resistance movements that oppose segregation. The sources of the research were: narratives of women in vulnerable situations, family members and health workers; interviews with strategic actors; document analysis; field journal. It became evident that vulnerabilities -linked to the criminalization of poverty and racial prejudice- have justified these separations. The lack of responsibility that State and society practice towards the support network for women, the devaluation of non-hegemonic productions of maternity, and the reinforcement of a 'reason of the world', that produces violence as a tool for exclusion establishing practical limits on the right to maternity. Women and children are disregarded in their singularities. Resistance movements have shown that intersectoral dialogues are an alternative to overcome discrimination and vulnerabilities.

Força muscular, distância percorrida e capacidade pulmonar na Doença Pulmonar Obstrutiva Crônica / Muscle strength, distance traveled and lung capacity in Chronic Obstructive Pulmonary Disease

Objetivo: Avaliar a força do músculo quadríceps e sua relação com a capacidade pulmonar em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC). Assim como a capacidade funcional destes pacientes e sua repercussão sobre a funcionalidade desses indivíduos. Métodos: Quarenta voluntários sendo vinte com diagnóstico de DPOC (grupo 1) e vinte saudáveis (grupo 2). Foi mensurado o pico de força (PF) do músculo quadríceps através do dinamômetro portátil MicroFETâ 2 (Hoggan Health Industries, West Jordan, UT, EUA), modo High Threshold. A capacidade pulmonar foi avaliada através do Teste de Caminhada de 6 minutos (TC6m). Resultados: Os pacientes com DPOC classificaram-se em média (61%) como GOLD II de acordo com os valores de VEF1/CVF. A idade média da amostra foi de 61±7 anos e IMC de 25±4 kg.m-2. Apenas 10% do grupo 1 pratica atividade física, e consequentemente obtiveram valores menor de PF (106±33)N comparado com o grupo 2 (163±45)N (p<0,05). O mesmo se repetiu na distância percorrida do TC6m, onde o grupo 1 percorreu uma média de 356±58m e o grupo 2 380±106m (p<0,05). Conclusões: Os pacientes com DPOC apresentam fraqueza muscular do quadríceps desde estágios iniciais da doença (GOLD II). Assim como percorreram uma distância menor do que os participantes saudáveis no TC6m, o que demonstra uma capacidade pulmonar limitada com declínio funcional e baixa tolerância ao exercício.

Cutaneous horn occurring on the oral tissues: report of a case and review of literature / Corno cutâneo nos tecidos orais: relato de caso e revisão da literatura

ABSTRACT The aim is to describe the clinical-pathological and treatment data of a patient with a cutaneous horn (CH) arising on oral tissues and to compare this with a literature-review. This case affects the lower-lip of an 86-years-old female. After excisional biopsy, the histopathological examination revealed a CH associated with actinic cheilitis. Only 23 similar cases have been reported in literature. At this site CH mainly affects the lower-lip of white males in a wide-age range. Excision should be the treatment of choice to enable pathological examination of the underlying lesion, since most cases were associated with pre-malignant/malignant lesions.

RESUMEN El objetivo es describir los datos clinicopatológicos y de tratamiento de una paciente de 86 años con un cuerno cutáneo (CC) en los tejidos orales (labio inferior) y compararlos con una revisión de la literatura. Tras la biopsia escisional, el examen histopatológico reveló un CC asociado a queilitis actínica. Solo se han informado 23 casos similares en la literatura. El estudio ha revelado que el CC afecta principalmente al labio inferior de los hombres blancos en un amplio rango de edad. La escisión debe ser el tratamiento de elección para permitir el examen patológico de la lesión subyacente, ya que la mayoría de los casos se asociaron con lesiones premalignas/malignas.

RESUMO O objetivo deste relato é descrever os dados clinicopatológicos e de tratamento de uma paciente, 86 anos, com corno cutâneo (CC) nos tecidos orais (lábio inferior) e compará-los com outros estudos publicados, fazendo uma revisão da literatura. Após biópsia excisional, o exame histopatológico revelou CC associado a queilite actínica. Apenas 23 casos semelhantes já foram relatados. Durante nossa pesquisa, verificamos que o CC afetou principalmente o lábio inferior de homens brancos em uma ampla faixa etária. A excisão deve ser o tratamento de escolha, pois ela possibilita a realização de exame histopatológico da lesão subjacente, já que a maioria dos casos foi associada a lesões pré-malignas/malignas.

Moedas complementares digitais e políticas públicas durante a crise da COVID-19 / Monedas complementarias digitales y políticas públicas durante la crisis de COVID-19 / Digital complementary currencies and public policies during the COVID-19 pandemic

Resumo Programas de renda básica têm sido utilizados em todo o mundo como uma ferramenta para mitigar os efeitos adversos da crise da COVID-19. No Brasil, a implementação de iniciativas federais de renda básica emergencial (RBE) enfrenta um duplo desafio: a logística de distribuição de dinheiro e os critérios de elegibilidade dos cidadãos. No entanto, iniciativas de moedas complementares existem há muitos anos no Brasil, estando associadas especialmente aos bancos comunitários, os quais operam no nível local e possuem conhecimento mais aprofundado sobre as necessidades dos moradores. Este artigo analisa o uso de moedas digitais complementares no enfrentamento de desafios de distribuição de renda. Apresentamos o caso da moeda complementar digital Mumbuca E-Dinheiro, adotada pelo município de Maricá (RJ). Discutimos como esta iniciativa permitiu a distribuição de renda de forma rápida e segura com o objetivo de mitigar os efeitos da pandemia da COVID-19 no Brasil. Sugerimos que, no momento atual, a RBE poderia ser paga através do E-dinheiro, começando pelos municípios nos quais ele já atua e depois se expandindo para os demais. A interoperabilidade com outros atores do ecossistema de pagamentos e articulações com governos locais são medidas adicionais para dar escala ao uso das moedas complementares digitais no combate à crise do coronavírus.

Resumen Los programas de ingresos básicos se han utilizado en todo el mundo como una herramienta para mitigar los efectos adversos de la crisis de COVID-19. En Brasil, la implementación de iniciativas federales de ingresos básicos de emergencia enfrenta un doble desafío: la logística de distribución de dinero y los criterios de elegibilidad de los ciudadanos.

Sugerimos que, en el momento actual, los ingresos básicos de emergencia podrían pagarse a través de la plataforma E-Dinheiro, comenzando por los municipios en que esta plataforma ya opera y luego expandiéndose a los demás. La interoperabilidad con otros actores del ecosistema de pagos y los vínculos con los gobiernos locales son medidas adicionales para ampliar el uso de monedas complementarias digitales en la lucha contra la crisis del coronavirus.

Abstract Basic income programs have been used worldwide as a tool to mitigate the adverse effects of the COVID-19 pandemic. In Brazil, the implementation of federal emergency basic income initiatives faces a twofold challenge: money distribution logistics and eligibility criteria. This paper analyses the use of digital complementary currencies (DCC) to face these challenges. Complementary currencies have long existed in Brazil as part of community banks. The latter are institutions that operate at the local level and have better information regarding residents' needs. We present the case of Mumbuca E-Dinheiro, a DCC adopted by the municipality of Maricá (RJ), and discuss how this initiative has enabled quick and safe cash distribution aimed at mitigating the effects of the COVID-19 pandemic in Brazil. We suggest that, at present, basic emergency income could be distributed through the E-Dinheiro platform, starting with the municipalities in which it already operates and then expanding to others. Interoperability with other actors in the payment ecosystem and connections with local governments are additional actions to scale up the use of digital complementary currencies to combat the coronavirus crisis.

Infecção e fatores preditivos de óbito em pacientes queimados atendidos em um hospital universitário na cidade de Uberaba/MG / Infection and predicting factors of death in burnt patients attended in a university hospital in the city of Uberaba/MG

OBJETIVO: Avaliar a ocorrência de infecções e as variáveis associadas a óbito entre pacientes queimados atendidos em um hospital universitário na cidade de Uberaba/MG. MÉTODO: Estudo retrospectivo realizado por análise dos prontuários de pacientes queimados (2° e/ou 3° graus) internados entre janeiro de 2013 e janeiro de 2019. Foram avaliados tempo de internação, internação em unidade de terapia intensiva (UTI), uso de antibióticos, superfície corporal queimada (SCQ), infecções, vias de acesso e comorbidades anteriores. Os dados foram tabulados no Microsoft® Excel e analisados por IBM SPSS statistics 21 e GraphPad Prism 7.0 (p<0.05). RESULTADOS: Foram avaliados 168 prontuários de pacientes com idades entre 0,12 e 84 anos (p=0,58). A ocorrência de infecção foi correlacionada a um risco relativo (RR) de quase seis vezes maior de óbito (RR=5,96; p=0,003). Pacientes com SCQ superior a 50% apresentaram RR cerca de 18 vezes maior de óbito (RR=18,33; p<0,0001). Demonstrou-se também aumento do número de óbitos em pacientes com mais de três acessos (RR=35,53; p <0,0001) e associação de óbitos com os custos hospitalares de internação (p=0,0018). Raça, sexo, tempo de hospitalização, hospitalização em UTI, comorbidades, uso de antibiótico e grau de queimadura não interferiram na sobrevida dos pacientes avaliados. CONCLUSÕES: A incidência de infecções entre os pacientes queimados avaliados apresentou relação positiva com óbito, bem como a SCQ, o número de acessos utilizados e os gastos hospitalares. Atenção especial deve ser dada ao controle de infecções, visto ser esta uma variável possível de alteração mediante esforços e cuidados da equipe multiprofissional responsável por esses pacientes.

OBJECTIVE: To evaluate the occurrence of infections and the variables associated with death among burn patients treated at a university hospital in the city of Uberaba/MG. METHODS: Retrospective study performed by analyzing the medical records of burned patients (2nd and/or 3rd degrees) hospitalized between January 2013 and January 2019. Length of stay, intensive care unit (ICU) stay, use of antibiotics, burned body surface (BBS), infections, access routes and previous comorbidities were evaluated. The data were tabulated in Microsoft® Excel and analyzed by IBM SPSS statistics 21 and GraphPad Prism 7.0 (p<0.05). RESULTS: 168 medical records of patients aged 0.12 to 84 years (p=0.58) were evaluated. The occurrence of infection was correlated with a relative risk (RR) of almost six times higher of death (RR=5.96; p=0.003). Patients with BBS greater than 50% had about 18 times higher risk of death (RR=18.33; p <0.0001). There was also an increase in the number of deaths in patients with more than three accesses (RR=35.53; p <0.0001) and an association of deaths with hospitalization costs (p=0.0018). Race, sex, length of hospital stay, ICU, stay comorbidities, use of antibiotics and degree of burn did not interfere with the survival of the evaluated patients. CONCLUSIONS: The incidence of infections among the burn patients evaluated showed a positive relationship with death, as well as BBS, the number of accesses used and hospital expenses. Special attention should be given to infection control, as this is a variable that can be controlled through the efforts and care of the multidisciplinary team responsible for these patients.

Determination of tnf-a gene polymorphisms on skeletal pattern in class ii malocclusion

Abstract Bone development and growth is a non-going, life-long process, varying greatly among individuals and much of this variation could be modulated by genetic factors. The purpose of this study was to evaluate the association between the polymorphisms in the TNF-a gene and skeletal class II malocclusion. Single nucleotide polymorphisms in TNF-a (rs1799724; rs1800629) gene were studied in 79 skeletal class II malocclusion and 102 skeletal class I malocclusion subjects from Straight Wire Group of Studies on Orthodontics and Functional Orthopedics for Maxillary from Rio de Janeiro, Brazil. The Genotyping of these selected polymorphisms was carried out by TaqMan real-time PCR using genomic DNA extracted from buccal cells. All allele and genotype frequencies were compared between the groups using the PLINK® software in a free, in a dominant and in a recessive model using a chi-square test (p≤0.05). There was no significant association of TNF-a (rs1799724; rs1800629) genotype and allele distribution with skeletal class II malocclusion. Regardless of the dominant or recessive genetic model, the preferential genotype associations for rs1799724 and rs1800629 was insignificant. In conclusion, no evidence of association is apparent between genetic polymorphisms involving TNF-a and skeletal class II malocclusion or the position of the maxilla and mandible in the postero-anterior direction.

Resumo O desenvolvimento e crescimento ósseo é um processo contínuo, que dura toda a vida, variando muito entre os indivíduos e grande parte dessa variação pode ser modulada por fatores genéticos. O objetivo deste estudo foi avaliar a associação entre os polimorfismos no gene TNF-a e a má oclusão da classe II esquelética. Polimorfismos no gene TNF-a (rs1799724; rs1800629) foram estudados em 79 indivíduos com má oclusão esquelética de classe II e 102 indivíduos com má oclusão esquelética classe I do Grupo de Estudos em Ortodontia e Ortopedia Funcional dos Maxilares do Rio de Janeiro, Brasil. A genotipagem destes polimorfismos foi realizada por PCR em tempo real, através de DNA genômico extraído de células bucais. Todas as frequências alélicas e genotípicas foram comparadas entre os grupos utilizando o software PLINK® em um modelo livre, dominante e recessivo. Foi aplicado o teste do qui-quadrado (p≤0,05). Não houve associação significativa na distribuição genotipica e alélica do gene TNF-a (rs1799724; rs1800629) com a má oclusão de classe II esquelética. Independentemente do modelo genético dominante ou recessivo, as associações genotípicas preferenciais para rs1799724 e rs1800629 foram insignificantes. Pode-se concluir que, não existe evidência de associação entre polimorfismos genéticos envolvendo TNF-a e má oclusão esquelética de classe II ou a posição da maxila e mandíbula na direção póstero-anterior.

Therapeutic Communities In Latin America: An International Descriptive Study In Different Countries Across Latin America / Comunidades terapéuticas en Latinoamérica: un estudio descriptivo en varios países de Latinoamérica

ABSTRACT Objective: In Latin America is not known for certain the quantity or quality of therapeutic communities (TCs) available in the region. The objective of this study is to describe and quantify the quantity and quality of the existing TCs in 5 different countries. Design: A multicenter quantitative description of the TCs was conducted in Argentina, Brazil, Colombia, Mexico and Peru. Methods: A survey was realized through the TCs regulatory entities of each country that accepted to participate in the study. Results: Of the 285 TCs identified in the 5 countries, 176 (62%) accepted to participate in this study. The TCs quality vas evaluated according to the scoring system stablished by De Leon, finding that 70% of the facilities have scores of 11/12 or 12/12 using these criteria. We also found that the majority of the De Leon criteria are known by more than 90% of the institutions, however, the dimensions of "separation of the community" and "encounter groups between residents" were the least known with 63 and 85% respectively. The main reasons for abandonment of TCs were "not accepting the rules of the institution", "lack of money" and "not feeling comfortable with the facilities". 98% of the TCs provided services to other substance abuse problems, 94% for alcohol and 40% for other types of substances. Conclusions: The majority of the TCs identified in our sample meet the quality criteria stablished by De Leon, mostly providing services for substance abuse. However, they should put in place additional policies to improve the unfulfilled conditions and investigate the reasons for the dissatisfaction and abandonment of these institutions.

RESUMEN Objetivo: En Latinoamérica no se conoce a ciencia cierta la cantidad o la calidad de las comunidades terapéuticas disponibles en los distintos países de la región. El objetivo de este estudio es identificar y describir la cantidad y la calidad de las comunidades terapéuticas existentes en 5 países de la región. Diseño: Se realizó un estudio multicéntrico descriptivo cuantitativo de las comunidades terapéuticas en Argentina, Brasil, Colombia, México y Perú. Métodos: Mediante las entidades reguladoras de las comunidades terapéuticas de cada país, se realizó una encuesta a las que aceptaran participar en el estudio. Resultados: De las 285 comunidades terapéuticas identificadas en los 5 países, 176 (62%) aceptaron participar en el estudio. La calidad de las comunidades terapéuticas se evaluó por las puntuaciones establecidas con los criterios de De León; se encontró que el 70% de las instituciones tienen puntuaciones de 11/12 o 12/12 según estos criterios. También se encontró que cumplen la mayoría de los criterios de De León más del 90% de las instituciones; sin embargo, las dimensiones «separación de la comunidad¼ y «grupos de encuentro entre residentes¼ fueron los menos cumplidos (el 63 y el 85% de las comunidades respectivamente). Las principales razones de abandono de las comunidades terapéuticas fueron no aceptar las normas de la institución, falta de recursos económicos y no sentirse a gusto con ella. El 98% de las comunidades terapéuticas prestaban servicios para problemas de abuso de otras sustancias, el 94% para abuso de alcohol y el 40% para otros tipos de abusos. Conclusiones: La mayoría de las comunidades terapéuticas identificadas en nuestra muestra cumplen los criterios de calidad establecidos por De León, y en su gran mayoría prestan servicios para abuso de sustancias, pero deben instaurarse políticas para mejorar las condiciones no cumplidas e indagar los motivos de las disconformidades y el abandono de estas instituciones.

Estudo comparativo entre dois programas de computador (Dolphin Imaging® e Nemotec®) e método manual para análises cefalométricas de pacientes com deformidade dentofacial Padrão II / Comparative study of two computer software programs (Dolphin Imaging® and Nemotec®) and a manual method of cephalometric analysis for patients with dentofacial deformity Class II

Este estudo analisou traçados digitais obtidos por dois programas de computador (Dolphin Imaging® e Nemotec®) em comparação aos obtidos pelo método manual nas análises cefalométricas SNA, SNB, Co-A, Co-Gn, altura facial anterior, A-Nperp, Pg-Nperp e plano mandibular. 30 pacientes leucodermas, portadores de retrognatismo mandibular, foram avaliados e submetidos à cirurgia ortognática para correção da deformidade por meio da osteotomia sagital do ramo mandibular. Os traçados cefalométricos foram realizados em telerradiografias laterais obtidas uma semana antes da cirurgia. O método Manual e o Nemotec® apresentaram excelente confiabilidade em todas as medidas. Por outro lado, o método Dolphin Imaging® apontou baixa confiabilidade nas medidas altura facial anterior, Co-A e Co-Gn. Nas medidas A-Nperp, Pg-Nperp, Plano md, SNA e SNB, não houve diferença entre três métodos estudados. Na medida altura facial anterior, houve diferença entre os métodos Dolphin Imaging® e Nemotec®, mas não foram observadas diferenças em relação ao método manual. Nas medidas Co-A e Co-Gn, foi observado que o método Dolphin Imaging® apresentou média significativamente inferior aos demais métodos estudados. No método manual, somente as medidas Co-Gn, Pg-Nperp e SNB confirmaram o diagnóstico de retrognatismo mandibular, tendo o programa Nemotec® apresentado resultados melhores que o programa Dolphin Imaging®... (AU)

This study analyzed digital tracings obtained by two different computer software programs (Dolphin Imaging® and Nemotec®) and compare them to the manual method using cephalometric measurements SNA, SNB, Co-A, Co-Gn, anterior facial height, A-Nperp, Pg-Nperp and mandibular plane. Thirty Caucasian patients exhibiting mandibular retrognathia were analyzed and were submitted to orthognathic surgery to correct the deformity by bilateral sagittal split osteotomy. The cephalometric tracings were performed with lateral radiographs that were obtained a week prior to the surgery. The manual method and the Nemotec® software exhibited an excellent reliability in all measurements. However, the Dolphin Imaging® method exhibited low reliability in the anterior facial height, Co-A and Co-Gn measurements. For the measurements of A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB, there were no significant differences between the three methods studied. For the anterior facial height measurement, a statistically significant difference was found between the Dolphin Imaging® and Nemotec® methods, although not in relation to the manual method. For the Co-A and Co-Gn measurements, the Dolphin Imaging® method exhibited a significantly lower mean than the other methods studied. In manual method, only the Co-Gn, Pg-Nperp and SNB measurements confirmed the diagnosis of mandibular retrognathia and Nemotec® software provided better results than Dolphin Imaging®... (AU)

Margens cirúrgicas no dermatofibrossarcoma protuberans: relato de caso e revisão da literatura / Surgical margins of dermatofibrosarcoma protuberans: case report and literature review

Introdução: O dermatofibrossarcoma protuberante (DFSP) é um tumor fibrohistiocítico de origem dérmica raro, que acomete a pele, representando 1% dos sarcomas de partes moles e menos de 0,1% de todas malignidades. A principal característica deste tipo de tumor é a sua elevada taxa de recidiva local após excisão cirúrgica. Decidir a margem cirúrgica adequada para a ressecção completa é um desafio. Relato de caso: 24 anos, apresenta lesão tumoral vegetante avermelhada no ombro esquerdo, assintomática. Possui história familiar positiva de DFSP em membro inferior. O laudo histopatológico definitivo confirmou Dermatofibrossarcoma protuberans. Discussão: A característica histológica do tumor é a presença de projeções tipo tentáculos de células neoplásicas na periferia que se estendem através do tecido subcutâneo até a fáscia muscular. Certamente, o fator de maior importância para o controle local é a obtenção de margens cirúrgicas livres. A excisão através da cirurgia micrográfica de Mohs é uma ótima opção em regiões onde a excisão ampla não é desejável, como na face. A margem padrão estabelicida em grande parte da literatura é de 3 cm com ressecção até a fáscia muscular, podendo ser diminuida para 2 cm em locais em que a excisão ampla prejudique a conformação do local, como na face.

Dermatofibrosarcoma protuberans (DFSP) is a rare dermal fibrohistiocytic tumor that affects the skin, accounting for 1% of soft tissue sarcomas and representing less than0.1% of all malignancies. The main characteristic of this type of tumor is a high rate of local recurrence after surgical excision. Deciding the proper surgical margin for complete resection is a challenge. Case report: 24 year-old, shows a reddish vegetative asymptomatic tumor on the left shoulder. She has a positive family history of DFSP in the lower limb. The definitive histopathological report confirmed Dermatofibrossarcoma protuberans. Discussion: The histological feature of the tumor is the presence of tentacle type projections of neoplastic cells in the periphery extending through the subcutaneous tissue to the muscular fascia. Of course, the most important factor for local control is the achievement of free surgical margins. Excision through Mohs micrographic surgery is a great option in regions where wide excision is not desirable, as in the face. The standard margin in most pf the literature is 3 cm resected to the muscular fascia, and it can be reduced to 2 cm in places where the extensive excision impairs the conformation of the site, as in the face.

Lobomycosis: a therapeutic challenge

Abstract: Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.

Serum immunoglobulin from Nellore cattle produced by in vitro fertilization and treated for umbilical diseases / Imunoglobulinas séricas de bovinos Nelore produzidos por fertilização in vitro e tratados para onfalopatias

The aim of this study was to measure serum immunoglobulin concentrations of Nellore cattle produced by in vitro fertilization (IVF) with umbilical diseases and to evaluate surgical excision as a method of treatment. Sixteen cattle with ages ranging from 1 to 15 months, males and females, affected by umbilical diseases were enrolled in the study. Blood samples were collected for cell counts and the determination of immunoglobulin concentrations by electrophoresis and zinc sulphate turbidimetry (ZST). Four calves were presented with umbilical herniation, two with an umbilical herniation associated with a persistent urachus, two with an umbilical herniation with a persistent urachus and omphaloarteritis, three with an umbilical herniation and an urachal diverticulum, three with a persistent urachus, one with an urachal diverticulum, and one with omphalitis. The blood cell counts pre- and post-surgical revealed differences in cell volume and the number of leukocytes. The immunoglobulin values measured by electrophoresis values were below normal in most animals, whereas the ZST showed normal levels in most of them. Most of the calves affected by umbilical diseases and produced by IVF presented hypoglobulinaemia. Correlations between umbilical diseases, failure of passive transfer of immunity and IVF could not be demonstrated.(AU)

Os objetivos desse estudo foram mensurar as concentrações séricas das imunoglobulinas de bovinos Nelore, produzidos por fertilização in vitro (FIV), acometidos por onfalopatias e avaliar a excisão cirúrgica como método de tratamento. Utilizou-se 16 animais, com idade variando de 1 a 15 meses, machos e fêmeas, acometidos por afecções umbilicais. Amostras de sangue foram colhidas para realização de hemogramas e avaliação das imunoglobulinas, por meio de eletroforese e turbidimetria com sulfato de zinco. Foram observados quatro casos de hérnias umbilicais, dois de hérnia umbilical associadas à persistência de úraco, dois casos de hérnia umbilical com persistência de úraco e onfaloarterite, três de hérnia umbilical com divertículo de úraco, três casos de persistência de úraco, um de divertículo de úraco e um de onfalite. O hemograma revelou diferença significativa para os valores de Volume Globular e Leucócitos, nos momentos pré e pós-tratamento cirúrgico dos animais. A eletroforese evidenciou valores de imunoglobulina abaixo da normalidade na maioria dos animais, enquanto que a turbidimetria apresentou níveis normais na maioria dos bovinos, quando comparados com valores de referência. A maioria dos bovinos estudados, acometidos de onfalopatias e concebidos por FIV, apresentaram hipoglobulinemia. Os resultados obtidos não permitem afirmar que existe relação entre as onfalopatias, falha de transferência de imunidade passiva e FIV.(AU)

[ARTIGO RETRATADO] Percepção dos Professores de Medicina de uma Escola Pública Brasileira em relação ao Sofrimento Psíquico de Seus Alunos / [RETRACTED ARTICLE] The Psychological Distress Suffered by Medical Students at a Brazilian Public university from the Viewpoint of their Teachers

RESUMO O sofrimento psíquico do estudante de Medicina é conhecido e já estudado. O papel do professor em detectar dificuldades geradoras de sofrimento psíquico em seus alunos e saber como lidar com elas é fundamental para a prevenção desse sofrimento. Entretanto, nem sempre os professores estão preparados para esses desafios. Objetivo: Estudar a percepção dos docentes do curso de Medicina da Universidade Federal de Minas Gerais (UFMG) em relação ao sofrimento psíquico de seus alunos. Método: Estudo transversal quantitativo realizado com os docentes do ciclo profissional do curso de Medicina da UFMG. A amostra de 102 docentes foi obtida por sorteio aleatório e dividida em quatro estratos: masculino até dez anos de docência, masculino com mais de dez anos, feminino com até dez anos de docência e feminino com mais de dez anos. Foi elaborado um questionário autoaplicativo de 28 itens com cinco opções da escala de Likert. Para análise dos dados foram construídos quatro indicadores: indicador de percepção de sofrimento psíquico (IPSP), indicador de compromisso do professor com as dificuldades emocionais do estudante (ICDE), indicador de atuação frente ao sofrimento psíquico (IAPS) e indicador geral (IG). Realizou-se análise dos quartis e calculou-se a diferença entre os grupos utilizando testes não paramétricos. Cinco questões não incluídas nos indicadores foram analisadas separadamente. Resultados: Dos 102 sorteados, 79 docentes responderam e sete se negaram a participar da pesquisa. Foi constatada preocupação com o sofrimento psíquico dos estudantes, variável entre os estratos. Para o IG, as professoras com mais tempo de docência obtiveram a mediana mais elevada em relação aos homens com menos tempo (p < 0,05). Para os demais indicadores, apesar da diferença entre os quartis, a comparação das medianas não mostrou diferenças estatisticamente significativas. Para as perguntas não incluídas nos indicadores, do total de professores, 85% já tiveram alunos com dificuldades emocionais. Os homens, com maior frequência, afirmaram desconhecer a existência de problemas emocionais entre os estudantes. Houve desconhecimento das instâncias de acolhimento psicólogico aos estudantes por 16,5% dos professores. A ocorrência de bullying na FMUFMG não foi percebida por mais de 50% dos professores. Apenas 28% admitiram que seus atos ou atitudes teriam desencadeado sofrimento psíquico no estudante. Ao se perguntar sobre apoio ao professor, 75,9%desejavam uma instância de apoio emocional ao professor. Conclusão: Este estudo, apesar das limitações, é inédito ao avaliar a percepção do docente do curso de Medicina em relação ao sofrimento psíquico dos estudantes. Tempo de docência e sexo feminino parecem exercer um papel importante na percepção do docente sobre o sofrimento psíquico do estudante. Parcela significativa de professores desconhece a existência das instâncias de apoio psicológico aos estudantes. Situações de assédio e bullying na escola médica permanecem negadas por muitos docentes.

ABSTRACT The psychological distress suffered by medical students is well-known. The role of the teaching staff in detecting difficulties causing students psychological distress and their knowledge of how to handle them is fundamental for preventing such problems. However, medical teachers are not always prepared to deal with these challenges. Objective: To study the perception of the teaching staff of the medical school at the Universidade Federal de Minas Gerais (FMUFMG) concerning the psychological distress of the students. Method: A cross-sectional quantitative study carried out with the faculty of the UFMG medical school. The sample of 102 teachers was obtained by random draw and divided into four groups: males with up to ten (10) years of teaching, males with more than ten (10) years, females with up to ten (10) years of teaching, and females with more than ten (10)years. A self-applied 28-item questionnaire with a 5-point Likert scale from strongly agree to strongly disagree was prepared. For the data analysis four indicators were elaborated: psychological distress perception indicator (IPSP), commitment of the teacher to the student emotional difficulties indicator (ICDE), performance in the face of psychological distress indicator (IAPS) and a general indicator (IG). Quartile analysis was carried out and the difference among the groups was calculated using nonparametric tests. Five questions that were not included in the indicators were independently analyzed. Results: Seven teachers refused to participate and 79 answers were collected.The results showed varying degrees of concern among the groups in relation to the psychological distress of students. For the IG, the female teachers with longer teaching experience obtained a higher median in relation to the men with less teaching experience (p<0.05). For the other indicators, despite the difference between the quartiles, the comparison of the medians showed no statistically significant differences. For questions not included in the indicators, it was shown that 85% of the sample had perceived psychological distress among their students. Male teachers more frequently deny psychological distress among students. 16.5% of the teachers did not know of any instances of institutional psychological care. The occurrence of bullying failed to be noted by more than 50% of the teachers. Only 28% of the teachers admitted that their actions or attitudes could precipitate a student's psychological distress. When questioned about emotional support for teachers, 75.9% would appreciate some institutional support. Conclusion: The present study, despite its limitations, is unique in assessing the perception of the medical teaching staff in relation to the psychological distress of the students. Teaching experience and being female seem to play an important role in the teacher's perception of psychological distress among students. A significant portion of the teaching staff ignores the existence of psychological support programs for students.
