RESUMO

OBJECTIVE: To evaluate the self-reported SB prevalence and explore associated risk factors in puerperal women who had given birth in Rio Grande, Southern Brazil. METHODS: A single, standardized questionnaire was given within the 48 h postpartum period. Self-reported SB was the main outcome investigated. Chi-square test was used to compare proportions, and Poisson regression with robust variance adjustment was used in the multivariate analysis. RESULTS: A total of 2225 women were included. Only 79 (3.6%) of these reported clenching or grinding their teeth during sleep. Adjusted analysis showed that the higher education level of the mothers (PR = 3.07; 95% CI 1.49-6.28; P = 0.006); living with three or more persons in the household (PR = 0.54; 95% CI 0.34-0.84; P = 0.007); medication intake during pregnancy (PR = 1.68; 95% CI 1.09-2.58; P = 0.017); smoking (PR = 1.93; 1.16-3.23; P = 0.024), or ever smoked (PR = 1.82; 95% CI 0.85-3.90; P = 0.024); severe anxiety (PR = 1.36; 95% CI 0.61-3.02; P = 0.005); and headache upon waking (PR = 4.19; 95% CI 1.95-9.00; P < 0.001) were significantly associated with self-reported SB. CONCLUSION FOR PRACTICE: Our data pointed towards new factors in a specific group of women that may be relevant for preventing sleep-related behaviors in the pregnancy-puerperal cycle. The higher levels of education, medication intake, smoking or even smoked, severe anxiety, the higher the probability of puerperal woman to self-report SB. The nighttime tooth clenching strongly increased headache upon waking.

RESUMO

OBJECTIVES: This systematic review compared minimally and invasive surgical procedures to manage arthrogenous temporomandibular joint (TMJ). MATERIALS AND METHODS: The review included clinical trials assessing surgical procedures of arthrogenous temporomandibular disorder (TMD) management by carrying out comparisons within the same surgical procedure (pre- and post-treatment) as well as between different surgical procedures. Meta-analyses were conducted only for similar comparison reporting the same outcome measures, visual analog scale (VAS) values to evaluate pain and maximum incisal opening (MIO) values. RESULTS: Of the 1,015 studies identified by the search strategy, 26 were selected for full-text reading, and 19 were included in the review. Of these, 16 studies were included in the meta-analysis and 3 in the qualitative analysis. The VAS scores showed significantly lower values after discectomies (p < 0.001) and discoplasties (p < 0.001) in the within-group comparison. Moreover, significantly lower VAS scores and higher MIO values were observed after discectomy compared to arthroscopy, eminectomy, and discoplasty (p < 0.05). CONCLUSION: The findings of this systematic review suggest that although significantly lower VAS scores and higher MIO values were observed after discectomy, the currently available scientific evidence is unclear, and the use of invasive surgical procedures should not be implemented as an efficient first-line treatment option for arthrogenous TMD management. CLINICAL SIGNIFICANCE: VAS and MIO outcomes could be insufficient to describe the success or failure of open surgical procedures like discectomy and discoplasty.

RESUMO

This in vitro study evaluated the influence of feldspathic ceramic thickness on the properties of light- and dual-cured resin cements. For each cement (RelyX Veneer, Allcem Veneer, RelyX Ultimate, and Allcem Dual), three ceramic specimens were prepared, with seven thicknesses for each (0.5, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5 mm). The degree of conversion, Vickers microhardness, irradiance power, color variation (ΔE00 ), and translucency parameters were assessed. Microhardness and irradiance power were analyzed using analysis of variance (ANOVA) with post hoc Tukey's test, while ΔE00 , translucency parameters, and degree of conversion were analyzed using ANOVA of ranks with post hoc Duncan's Multiple Range Test. The relationship between each of the dependent variables (degree of conversion, ΔE00 , and translucency parameter tests) and the specimen thickness was described using linear regression for each of the four resin cements. The significance level for all analyses was set at 5%. RelyX Ultimate yielded the lowest degree of conversion values among all resin cements. Allcem Veneer produced the lowest microhardness values, without statistical differences between thicknesses, of up to 1 mm. Allcem Dual produced the highest ΔE00 and translucency parameter values. Feldspathic ceramic thickness influenced the mechanical properties of resin cements and optical aspects of the restorative set.

RESUMO

OBJECTIVE: This cross-sectional clinical study evaluated the associations between sociodemographic, occupational, clinical conditions, psychological and sleep quality variables on definite sleep bruxism (SB). METHODS: All records obtained from adults (aged 20-60 years) and the elderly (aged >60 years) who had undergone polysomnography (PSG) at a private medical outpatients' clinic from July 2017 to February 2018 were reviewed. Data from a questionnaire, based on the criteria of the American Academy of Sleep Medicine (AASM), were also gathered. Definite SB data pattern distribution was analyzed, and multivariate Poisson regression with robust variance was used to assess the associations between definite SB diagnosis, determined via PSG recordings, and the independent variables. A significance level of 5% was adopted. RESULTS: A total of 240 individuals were included in the study and the SB prevalence was 7.08% (n = 17). The adjusted Poisson regression analysis revealed association between definitive SB and individuals with respiratory allergy (PR = 3.63; 95% CI:1.01-13; P = 0.047) and restless sleep (PR = 2.97; 95% CI:1.04-8.50; P = 0.042). CONCLUSION: This study found associations between definite SB and clinical conditions (respiratory allergy) and sleep behavior (restless sleep). Knowledge regarding factors associated with definite SB can contribute to decision making in the clinical setting and management strategies involving a multidisciplinary approach.

RESUMO

OBJECTIVE: This study evaluated the association between the diagnosis of sleep bruxism (SB), scored by way of polysomnographic (PSG) recordings, clinical conditions and sleep architecture. DESIGN: A case-control study was conducted. All records from adults who had undergone polysomnography (PSG) recordings at a private medical outpatient clinic between January 2015 and December 2017 were reviewed. The sample included 58 bruxers (case group) and 58 non-bruxers (control group), identified based on the PSG recording and matched by sex and age. RESULTS: Obese individuals had significantly lower chance (OR 0.18; 95 % CI: 0.05-0.62; P = 0.005) of an SB diagnosis than individuals with normal BMI. Alcohol consumption significantly increased (OR 2.74; 95 % CI: 1.11-6.78; P = 0.029) and OSA decreased the chances (OR 0.55; 95 % CI: 0.23-1.30; P = 0.173) of an SB diagnosis. Bruxers had a significantly shorter wake time after sleep onset (WASO) (p = 0.002). As far as non-rapid eye movement (NREM) is concerned, the duration of stage N1 was statistically shorter (p = 0.034) and the duration of stage N3 was statistically longer (p = 0.001) in bruxers. Arousals (p = 0.013), arousals per hour (p = 0.009), respiratory disturbance index (RDI) values (p < 0.0005) and the apnoea-hypopnea index (AHI) (p = 0.002) were all lower in bruxers than in non-bruxers. CONCLUSION: The results of this study support a significant association between SB diagnosis, BMI and alcohol consumption. SB modified the sleep architecture as statistically significant differences were found between bruxers and non-bruxers for WASO, NREM stage N1 and N3, arousals, arousals per hour, RDI and AHI.

RESUMO

Este estudo investigou as variações anatômicas do canal mandibular (CM) e do forame mentual (FM) em uma população do sul do Brasil utilizando exames de tomografia computadorizada de feixes cônicos (TCFC). Exames de 99 pacientes (198 hemimandíbulas) foram avaliados quanto à presença e localização de canais mandibulares duplos (CMD), presença e extensão de alça anterior do CM, presença de forame mentual acessório (FMA), e a relação entre FMA e CM. Em adição às estatísticas descritivas, o teste de Qui-quadrado e o teste Exato de Fisher compararam a ocorrência de variações anatômicas para cada lado da mandíbula e para o gênero dos pacientes. CMD foram encontrados em 63 hemimandíbulas (32,48%) e a maioria foi classificada como canal vestíbulo-lingual. Alça anterior do CM foi detectada em 14 hemimandíbulas (7%) com comprimento médio de 1,87±0,56 mm. FMA foi encontrado em apenas duas hemimandíbulas (1,1%) e um FMA estava em relação com o CM. O teste de Qui-quadrado não mostrou relação entre variações anatômicas e lado da mandíbula. Entretanto, a presença de CMD foi relacionada de forma estatisticamente significativa com o gênero masculino. CMD foi observado em um percentual significativo da população estudada e ocorreu mais em homens. Entretanto, outras variações anatômicas avaliadas através de TCFC não foram associadas de forma significativa com nenhuma outra variável abordada, sugerindo que essas variações não são prevalentes na população estudada (AU).

This study investigated the anatomical variations of the mandibular canal (MC) and mental foramen (MF) in a southern Brazilian population using cone beam computed tomography (CBCT). Exams of 99 patients (198 hemimandibles) were evaluated for the presence and location of double mandibular canals (DMC), the presence and extent of MC anterior loops, the presence of an accessory mental foramen (AMF), and the relationship between the AMF and the MC. In addition to descriptive statistics, Chi-squared and Fisher's exact tests compared the occurrence of anatomical variations to each side of the mandible and the gender of patients. DMC was found in 63 hemimandibles (32.48%) and most was classified as buccolingual canals. Anterior loops were detected in 14 hemimandibles (7%) and they averaged 1.87±0.56 mm in length. AMFs were found in only 2 hemimandibles (1.1%) and one AMF was related to the MC. Chi-square tests showed no relationship between the anatomical variations and the side of the mandible. However, DMC was significantly more common in men. DMC was observed in a significant percentage of the population and they occurred more frequently in men. However, others anatomical variations evaluated by CBCT were not significantly associated with any characteristic of the study population, suggesting that these are not prevalent variations in southern Brazilians (AU).

RESUMO

INTRODUÇÃO: Seiscentos anos antes de Cristo, foi descrito o retalho médio-frontal pelo indiano Sushruta Samhita. Até hoje, esse retalho, chamado ''retalho indiano", é usado na reconstrução do nariz. O objetivo deste trabalho foi analisar os resultados da 38ª Enfermaria da Santa Casa da Misericórdia do Rio de Janeiro, Serviço do Professor Ivo Pitanguy, na reconstrução nasal com emprego de retalho médio-frontal. MÉTODO: Foi realizado estudo retrospectivo com 10 casos operados no serviço referido para reconstrução nasal com retalho indiano, no período de 21 anos (1991 a 2012). RESULTADOS: O número de subunidades nasais atingidas variou de 4 a 9, com média de 6,5 subunidades. Em 70% dos pacientes foi realizada expansão prévia do retalho médio-frontal e em 90% foram utilizados enxertos cartilaginosos e/ou ósseos. Cinco pacientes apresentaram distorções pós-operatórias, que foram corrigidas por outras cirurgias. Nenhum caso de infecção pós-operatória, de necrose do retalho ou de extrusão de enxertos foi registrado. CONCLUSÕES: Este trabalho permitiu demonstrar que o retalho médio-frontal tem ainda importante papel na reconstrução nasal de grandes defeitos, com resultados satisfatórios, atribuídos a sua segurança vascular, à quantidade de pele que se obtém, e à semelhança de cor, textura e espessura cutâneas.

BACKGROUND: Six hundred years before Christ, the mid-forehead flap was described by the Indian Sushruta Samhita. Until today, this flap called ''Indian flap", has a major role in the reconstruction of the nose. The aim of this work was to analyze the results of the 38th Infirmary of the Santa Casa da Misericórdia of Rio de Janeiro, Professor Ivo Pitanguy's Service, in nasal reconstruction with the mid-forehead flap. METHODS: We did a retrospective study of 10 cases operated in the service for nasal reconstruction with Indian flap, during a 21 year period (1991-2012). RESULTS: The number of nasal sub-units affected varied from 4 to 9, with an average of 6.5 subunits. In 70% of the patients, was performed a previous expansion of the mid-forehead flap and in 90% were used cartilage grafts and/or bones. Five patients had postoperative distortions, that were corrected with other surgeries. No cases of infection, necrosis of the flap or graft extrusion were recorded. CONCLUSIONS: This study allowed to demonstrate that the mid-forehead flap still have an important role in nasal reconstruction of major defects, showing satisfactory results due to its vascular safety, the amount of skin which is obtained, likeness of color, texture and skin thickness.

RESUMO

INTRODUCTION: Human immunodeficiency virus (HIV) coinfection with Leishmania infantum or Leishmania donovani, the agents of visceral leishmaniasis (or kala-azar), has become a fatal public health problem in the tropics where kala-azar is endemic. METHODS: The clinical presentation of patients with HIV and L. infantum coinfection is described using two unique databases that together produce the largest case series of patients with kala-azar infected with HIV in South America. First, a retrospective study paired the list of all patients with kala-azar from 1994 to 2004 with another of all patients with HIV/AIDS from the reference hospital for both diseases in the City of Teresina, State of Piauí, Brazil. Beginning in 2005 through to 2010 this information was prospectively collected at the moment of hospitalization. RESULTS: During the study, 256 admissions related to 224 patients with HIV/L. infantum coinfection were registered and most of them were males between 20-40 years of age. Most of the 224 patients were males between 20-40 years of age. HIV contraction was principally sexual. The most common symptoms and signs were pallor, fever, asthenia and hepatosplenomegaly. 16.8% of the cohort died. The primary risk factors associated to death were kidney or respiratory failure, somnolence, hemorrhagic manifestations and a syndrome of systemic inflammation. The diagnosis of HIV and kala-azar was made simultaneously in 124 patients. CONCLUSIONS: The urban association between HIV and kala-azar coinfection in South America is worrisome due to difficulty in establishing the diagnosis and higher mortality among the coinfected then those with either disease independently. HIV/L. infantum coinfection exhibits some singular characteristics and due to its higher mortality it requires immediate assistance to patients and greater research on appropriate combination therapy.

RESUMO

INTRODUÇÃO: Várias vias de acesso foram criadas para a inclusão de implantes na cirurgia de aumento das mamas. Em 1966, Pitanguy descreveu a via de acesso transareolopapilar. O objetivo do presente estudo é avaliar as mamoplastias de aumento realizadas no Instituto Ivo Pitanguy (Rio de Janeiro, RJ, Brasil), nas quais se utilizou a incisão transareolopapilar, nos últimos 10 anos. MÉTODO: Realizado estudo retrospectivo, analisando-se os seguintes parâmetros: tamanho dos implantes, indicação da incisão transareolopapilar e complicações pós-operatórias, como alterações cicatriciais. RESULTADOS: Foram incluídas no estudo 53 pacientes, com média de idade de 33,54 anos e tempo médio de seguimento de 11,6 meses. A maioria (60,4 por cento) dos implantes possuía menos de 200 ml. Doze pacientes foram submetidas a reintervenções pelas seguintes razões: nódulo mamário (1 caso), infecção (1 caso), contratura capsular (1 caso), e insatisfação com a forma das mamas (4 casos), com o volume (4 casos) e com a cicatriz unilateral (1 caso). Dezesseis (30,2 por cento) pacientes desenvolveram alguma complicação menor no pós-operatório e 13 (24,5 por cento) apresentaram alguma alteração cicatricial no pós-operatório: hipocromia (18,9 por cento), hipertrofia unilateral (1,9 por cento), retração cicatricial unilateral (1,9 por cento), e aréola bífida (1,9 por cento). Vinte (37,7 por cento) pacientes realizaram seguimento pós-operatório superior a um ano e relataram satisfação com a cicatriz. CONCLUSÕES: A incisão transareolopapilar permite a inclusão de implantes de tamanho pequeno a moderado, com baixo índice de complicações pós-operatórias e cicatriciais, desde que seguida a correta técnica cirúrgica.

BACKGROUND: There are numerous access routes for inserting implants during breast augmentation surgery. In 1966, Pitanguy described the transareolopapilar route. The aim of this study was to assess the use of transareolopapilar incision during breast augmentation surgery at the Ivo Pitanguy Institute (Rio de Janeiro, RJ, Brazil), over the past 10 years. METHODS: Retrospective analyses of the size of the implants used, indications for transareolopapilar incision, postoperative complications, and postoperative scarring were performed. RESULTS: Fifty-three patients with a mean age of 33.54 years were included, and the mean follow-up period was 11.6 months. Most (60.4 percent) of the implants were <200 ml. Twelve patients required a second operation due to a breast lump (1 case); infection (1 case); capsular contracture (1 case); and dissatisfaction with breast shape (4 cases), volume (4 cases), and unilateral scarring (1 case). Sixteen (30.2 percent) patients developed some form of minor postoperative complication; 13 (24.5 percent) had one or more scarring issues, including hypochromia (18.9 percent), hypertrophy (1.9 percent), scar retraction (1.9 percent), and areola bifida (1.9 percent). Twenty (37.7 percent) patients underwent postoperative follow-up for more than one year and were satisfied with the postoperative scar. CONCLUSIONS: The transareolopapilar incision facilitates the insertion of small-to-moderate size implants with a low rate of postoperative complications and a low incidence of scarring, provided the correct surgical technique is used.

RESUMO

The diagnosis of visceral leishmaniasis (VL) is still a major problem in Brazil and several other countries where the disease is endemic. The use of an easy-to-use and interpret, sensitive, and specific method that requires no complex infrastructure or specialized professionals, such as direct agglutination test (DAT) and the rK39-based rapid immunochromatographic test may enhance the diagnosis of disease. This study evaluated the performance of a rapid test (DiaMed- IT-LEISH®) and the DAT for the diagnosis of VL in 213 parasitologically confirmed cases and 119 controls with clinical suspicion of VL and confirmation of another etiology. The sensitivities and specificities of the rapid test were 93% and 97%, respectively and those of the DAT were 90% and 96%, respectively. The positive predictive values of the rapid test and the DAT were 98% and 97%, respectively and the negative predictive values were 89% and 84%, respectively. The Kappa index showed agreement between both methods classified as substantial (0.77). This study showed that the DAT and the rapid test can be used to diagnose VL in Brazil, following a pilot study for implementation of the rapid test in the health services.

RESUMO

A trombose venosa profunda (TVP) e o seu desfecho imediato mais grave, o troboembolismo pulmonar (TEP), são complicações de incidência elevada em pacientes hospitalizados e principalmente naqueles submetidos à cirurgia. Objetivo: Apresentar o protocolo de profilaxia de Tromboembolismo (TEV) da Clínica Ivo Pitanguy, mostrando a incidência de TEV no serviço antes e a pós a introdução deste protocolo, assim como a incidência de hematomas, no período de cinco anos. Método: Estudo de revisão dos prontuários dos pacientes operados no período de julho de 2004 a maio de 2009. Comparou-se a incidência de eventos trombóticos antes e após a introdução do protocolo, assim como a incidência de hematomas. Resultados: Foram analisados 1700 prontuários. Desde a introdução do protocolo, não ocorreu nenhum caso de tromboembolismo venoso, em 711 pacientes operados. A incidência de hematomas com necessidade de revisão cirúrgica foi reduzida, provavelmente pelo controle pressórico mais rigoroso após a introdução do protocolo. Conclusão: O protocolo tem se mostrado de utilização simples e efetiva. Houve redução da incidência de TEV e hematomas a partir de sua introdução.

The deep vein thrombosis (DVT) and its most dangerous outcome, the pulmonary embolism (PE), are complications of high incidence in hospitalized patients and in those submitted to surgery. Objective: This study presents the guideline to prevention of thromboembolism at Ivo Pitanguy Clinic and its incidence before and after the introduction of this protocol, in a period of five years. We also relate the incidence of hematoma beforeand after the beginning of the protocol. Methods: The study consists of the revision of the medical records of all patients operated between July 2004 and May 2009. We compared the incidence of thromboembolic events before and after the beginning of the protocol as well as the incidence of hematomas that were submitted to revision at the surgery room. Results: Analyzing 1700 medical records, since the introduction of the guideline of prevention of VTE, there is no case of VTE in 711 operated patients. The incidence of reoperated hematomas at the surgery room was reduced, maybe because there was a more rigorous control of the blood pression after the introduction of the guideline. Conclusion: The guideline has shown itself practical and simple use. There were reduction in cases of VTE and hematomas after its introduction.

RESUMO

INTRODUCTION: The objective of the study is to identify the main risk factors for death by New World visceral leishmaniasis and establish a coherent pathogenic substrate of severe disease based on clinical findings. METHODS: Seventy-six deceased inpatients and 320 successfully treated inpatients with VL were studied in a case control study. RESULTS: Bacterial infection and bleeding were mutually exclusive events leading to death. Five risk factors were unique for death by bacterial infection (malnutrition, pulmonary rales, severe anemia, severe absolute neutropenia and higher neutrophil count), while another six were unique for death by bleeding (jaundice, severe relative neutropenia, severe thrombocytopenia, liver injury, kidney failure, higher bone marrow parasite load). Bacterial infection, bleeding, severe anemia, diarrhea, dyspnea, edema, jaundice and bone marrow parasite load were the main syndromes of visceral leishmaniasis among successfully treated patients. CONCLUSIONS: The data support the idea that bacterial infections are due to immune paralysis. Broad organ and system involvement is plausibly due to the high production of proinflammatory cytokines, whose actions fit well with visceral leishmaniasis. The syndromes and causative mediators are typical of a slowly developing systemic inflammatory response syndrome.

INTRODUÇÃO: O objetivo do estudo foi i dentificar os principais fatores de risco para morte na leishmaniose visceral do Novo Mundo e estabelecer um substrato patogênico baseado nos achados clínicos coerente para doença grave. MÉTODOS: Em um estudo caso-controle, foram estudados 76 pacientes internados que faleceram e 320 pacientes internados tratados com sucesso. RESULTADOS: Infecção bacteriana e sangramento foram eventos que levaram à morte, mutuamente exclusivos. Cinco fatores de risco foram únicos para morte por infecção bacteriana (desnutrição, estertores pulmonares, anemia grave, neutropenia absoluta grave e número de leucócitos aumentados), enquanto outros seis foram exclusivos para morte por sangramento (icterícia, neutropenia relativa grave, trombocitopenia grave, lesão hepática, insuficiência renal, maior carga de parasitas na medula óssea). Entre os pacientes tratados com sucesso, as principais síndromes de leishmaniose visceral foram infecções bacterianas, sangramento, anemia grave, diarreia, dispneia, edema, icterícia e carga de parasitas na medula óssea. CONCLUSÕES: Os dados apoiam a ideia de que as infecções bacterianas são secundárias a imunoparalisia. O amplo envolvimento de órgãos e sistemas é de forma plausível devido a elevada produção de citocinas pró-inflamatórias, cujas ações se encaixam com a leishmaniose visceral. As síndromes e os mediadores causais são típicos da síndrome de resposta inflamatória sistêmica, desenrolando-se lentamente.

RESUMO

Introdução: A displasia fibrosa é uma lesão óssea com etiologia ainda desconhecida. Caracteriza-se pela incapacidade de maturação óssea. Pode acometer qualquer osso, mas é o acometimento dos ossos craniofaciais o de maior interesse na otorrinolaringologia. A maxila é o osso facial mais afetado, sendo a invasão orbitária um evento incomum. Os sintomas são inespecíficos e, pela baixa suspeição e raridade, o diagnóstico é geralmente tardio. A forma monostótica apresenta crescimento lento e curso assintomático, necessitando apenas de acompanhamento. O tipo poliostótico possui um comportamento progressivo e associa-se a recorrência e complicações. Objetivo: Apresentar dois casos de pacientes com diagnóstico de displasia fibrosa, discutindo a apresentação clínica, os achados radiológicos e o tratamento desta patologia. Relato do Caso: São relatados dois casos de displasia fibrosa que inicialmente apresentaram sintomatologia inespecífica, mas com sinais radiológicos característicos. Foram submetidos a tratamento cirúrgico para ressecção das lesões e evoluíram com recidivas frequentes com acometimento extenso de seios da face, sendo que em um paciente ocorreu invasão de base do crânio havendo necessidade de craniotomia frontal para excisão tumoral. Conclusão: A displasia fibrosa é uma osteopatia incomum. A tomografia é o método de eleição na caracterização da expansão tumoral, auxiliando no planejamento cirúrgico. A estratégica cirúrgica está indicada em lesões sintomáticas, alterações funcionais ou distorções anatômicas. O presente artigo descreve duas raras apresentações de displasia fibrosa recidivante com extenso acometimento de antro maxilar, seios etmoidais e esfenoidais, além de invasão orbitária e base do crânio.

Introduction: Fibrous dysplasia is an osseous lesion with an unknown etiology. It is characterized by the osseous maturation insufficiency. It may affect any bone, but the affection of craniofacial bones is the most critical for otorhinolaryngology. Maxilla is the most affected facial bone and the orbitary invasion is an uncommon event. The symptoms are unspecific and for its low suspicion and uncommonness, the diagnosis is generally late. The monostotic form presents a slow growth and asymptomatic course and needs to be followed up. The polyostotic type has a progressive behavior and is associated to recurrence and complications. Objective: To present two cases of patients with fibrous dysplasia diagnosis and describe the clinical presentation, radiological findings and the treatment of this pathology. Cases Report: Two cases of fibrous dysplasia are reported, which initially presented unspecific symptomatology, but with characteristic radiologic signs. They were submitted to surgical treatment for resection of the lesions and evolved with frequent recurrences with extensive affection of the facial sinuses, one patient had cranial base invasion and frontal craniotomy was needed for tumoral excision. Final Comments: Fibrous dysplasia is an uncommon osteopathy. The tomography is the choice method for characterization of the tumoral expansion, and helps in the surgical planning. The surgical strategy is indicated for symptomatic lesions, functions alterations or anatomic disorders. This article describes two uncommon manifestations of recurrent fibrous dysplasia with an extensive affection of anthro maxillary, ethmoidal and sphenoid sinuses, in addition to orbitary and cranial base invasion.

RESUMO

O teste imunocromatográfico rápido IT-LEISH® (DiaMed IT-LEISH®) foi validado para o diagnóstico da leishmaniose visceral (LV) em quatro áreas endêmicas do Brasil. O desempenho do IT-LEISH® foi comparado ao da reação de imunofluorescência indireta; e ao da reação imunoenzimática, usando-se antígeno solúvel de Leishmania chagasi e recombinante K39 (rK39). O estudo incluiu 332 pacientes com quadro clínico sugestivo de LV: 213 casos de LV confirmados parasitologicamente; e 119 não-casos, com confirmação de outra etiologia. O teste IT-LEISH® apresentou sensibilidade de 93 por cento e especificidade de 97 por cento. As técnicas RIFI (imunofluorescência indireta), ELISA L. chagasi e ELISA rK39 apresentaram sensibilidade de 88 por cento, 92 por cento e 97 por cento e especificidades de 81 por cento, 77 por cento e 84 por cento, respectivamente. Os resultados confirmam a validade do teste IT-LEISH® para o diagnóstico da LV no Brasil...
