Reflectance confocal microscopy - Consensus terminology glossary in Brazilian Portuguese for normal skin, melanocytic and non-melanocytic lesions

Abstract Background: Currently, there is no uniform and official terminology in Portuguese for reflectance confocal microscopy analysis, despite the increasing number of Brazilian dermatologists using this new tool. Objective: To present the terminology in Brazilian Portuguese for the description of reflectance confocal microscopy and establish the first Brazilian consensus on terms related to normal skin and cutaneous tumors. Methods: 10 Brazilian specialists from different institutions and states of Brazil were selected to evaluate the best corresponding terms in Portuguese for normal skin, melanocytic and non-melanocytic tumors. The terms used were translated from international consensuses in the English language. The modified Delphi method was used to create the consensus in 3 steps. Results: The terms considered the most appropriate in the Portuguese language to describe the findings of normal skin, melanocytic and non-melanocytic lesions in the reflectance confocal microscopy analysis were presented. Study limitations: The limitations of the present study include the number of participants and limited regional representation (only two of the five Brazilian regions were represented). Conclusion: This Brazilian consensus represents an opportunity for dermatologists and physicians specializing in cutaneous oncology to become familiar with reflectance confocal microscopy, propagating the technique in clinical and research environments to stimulate national and international publications on this subject.

N-terminal pro-B-type Natriuretic peptide levels and left atrial appendage thrombosis in patients with persistent atrial fibrillation

Introduction: In hospitalized patients, atrial fibrillation is the most common arrhythmia, and leading cause of cardio-embolic stroke. Objective: To evaluate the association between N-terminal b-type natriuretic peptide pro (NT-proBNP) and left atrial appendage thrombus in persistent atrial fibrillation patients. Methods: A cross-sectional study, enrolled 139 patients with persistent non-valvular atrial fibrillation. Transthoracic and trans-esophageal echocardiographs were performed in all patients. Results: Mean age was 70.5 ( 10.6 years, 80.6% male. In patients with LAAT, NT-proBNP was positively correlated with left ventricular end diastolic diameter (LVEDD) (r=0.345), left ventricular end-systolic diameter (LVEDS) (r= 0.449), E/e' (r=0.445), and left atrial spontaneous echo contrast (LA SEC) (r=0.478), and negatively correlated with left ventricular ejection fraction (LVEF) (r=-0.473), left atrial strain (r= -0.301), strain rate (r= -0.283), and e'(r= -0.458). In patients without LAAT, NT-proBNP was positively correlated with LVEDD (r= 0.333), LVESD (r= 0.358), E (r= 0.318), E/e' (r= 0.411), left atrial volume index (LAVI) (r= 0.421), and negatively correlated with LVEF (r= -0.307). Plasma NT-proBNP (> 1279 pg/mL) could be used to predict LAAT (AUC= 0.639; Se= 67.7%, Sp= 60.2%). In patients with ejection fraction > 50%, the cutoff value of NT-proBNP to predict LAAT was 1325 pg/mL (AUC= 0.572; Se= 57.9%, Sp= 78.3%). Multiple logistic regression analysis showed that prior stroke, E/e' index, and NT-proBNP correlated with LAAT (r= 0.887; p< 0.001; r= -0.092, p= 0.035 and 0.022; p= 0.004, respectively). Conclusion: Plasma NT-proBNP levels and E/e' index are associated with LAAT in patients with persistent atrial fibrillation.

Introducción: En pacientes hospitalizados, la fibrilación auricular es la arritmia más común y causa principal de ictus cardioembólico. Objetivo: Evaluar la asociación entre el péptido natriurético NT proBNP y el trombo en la orejuela auricular izquierda en pacientes con fibrilación auricular persistente. Métodos: Se reclutaron prospectivamente 139 pacientes con fibrilación auricular no valvular persistente. Se realizaron ecocardiografías transtorácicas y transesofágicas en todos los pacientes. Resultados: Edad media, 70,5±10,6 años; 80,6 % hombres. En pacientes con LAAT, NT-proBNP correlacionó positivamente con el diámetro telediastólico del ventrículo izquierdo (DDVI) (r=0,345), diámetro sistólico final del ventrículo izquierdo (DSVI) (r=0,449), E/e' (r=0,445) y contraste de eco espontáneo auricular izquierdo (LA SEC) (r=0,478), y negativamente con la fracción de eyección del ventrículo izquierdo (FEVI) (r=-0,473), tensión auricular izquierda (r=-0,301), tasa de tensión (r=0,283) y e' (r=-0,458). En pacientes sin LAAT, NT-proBNP correlacionó positivamente con LVEDD (r= 0,333), LVESD (r=0,358), E (r=0,318), E/e' (r=0,411), índice de volumen auricular izquierdo (LAVI) (r=0,421), y negativamente con FEVI (r=-0,307). NT-proBNP plasmático (>1279 pg/mL) podría usarse para predecir LAAT (AUC=0,639; Se=67,7 %, Sp=60,2 %). En pacientes con fracción de eyección >50 %; valor de corte de NT-proBNP para predecir LAAT fue 1325 pg/mL (AUC=0,572; Se=57,9 %, Sp=78,3 %). Según regresión logística múltiple, el accidente cerebrovascular previo, el índice E/e' y NT-proBNP se correlacionaron con LAAT (r=0,887; p<0,001; r=0,092, p=0,035 y 0,022; p=0,004, respectivamente). Conclusiones: Los niveles plasmáticos de NT-proBNP y el índice E/e' se asocian con el OAI en pacientes con FA persistente.

Primera colocación del dispositivo AMPLATZER™, Amulet™ para cierre de orejuela en Costa Rica utilizando Heart Navigator / First placement of the AMPLATZER™ Amulet™ device for appendage closure in Costa Rica using Heart Navigator

RESUMEN El cierre de la orejuela izquierda mediante un dispositivo facilita la prevención de un accidente cerebrovascular en pacientes con antecedente de fibrilación auricular no valvular y contraindicación para el uso de medicamentos anticoagulantes. Este artículo presenta dos casos de pacientes con historia de fibrilación auricular en el Hospital Calderón Guardia, ambos con el antecedente de sangrado digestivo y contraindicación para la anticoagulación, en los que se logró el cierre de la orejuela izquierda mediante la colocación exitosa del dispositivo AmuletTM, utilizando TAC y Heart Navigator, técnicas de imagen que se están convirtiendo en el estándar de oro de muchos centros internacionales de referencia en cardiología intervencionista.

ABSTRACT Closure of the left atrial appendage with a device facilitates the prevention of stroke in patients with a history of nonvalvular atrial fibrillation and a contraindication to the use of anticoagulant medications. This article presents two cases of patients with a history of atrial fibrillation at the Calderón Guardia Hospital, both with a history of digestive bleeding and contraindication to anticoagulation, in whom closure of the left atrial appendage was achieved through successful placement of the AmuletTM device, using CT and Heart Navigator, imaging techniques that are becoming the gold standard in many international reference centers in interventional cardiology.

Giant Left Atrial Appendage Aneurysm or Pericardial Effusion: A Misleading Appearance on Echocardiography and a High Risk of Rupture

Left atrial appendage (LAA) aneurysm or giant LAA is an uncommon condition. It could be discovered incidentally during echocardiography examination or in symptomatic patients presenting with tachycardia or embolic events. The giant LAA is a serious condition with a high embolic risk that can cause respiratory distress and even cardiac arrest in children. A conservative surgical approach based on resection of the LAA is recommended and is mostly safe. We report the case of a four-year-old girl presenting with a symptomatic giant LAA removed successfully. The echo-cardiographer must be aware of its appearance mimicking a pericardial effusion and focus on its possible association with other congenital lesions. There are several therapeutic strategies, all with proven efficacy and safety.

Does left atrial appendage morphology and dimension differ amongst etiological stroke subtypes in patients without known atrial fibrillation? Results from the left atrial appendage morphology and dimension assessment by TEE in patients with stroke without known atrial fibrillation (LAMDA-STROKE) study

Context: Complex left atrial appendage (LAA) morphology is increasingly associated with cryptogenic ischemic stroke as compared to cardioembolic stroke due to atrial fibrillation (AF). However, data on such an association in patients with other etiological stroke subtypes in the absence of AF is limited. Aim: The study aimed to assess the LAA morphology, dimension and other echocardiographic parameters by transesophageal echocardiography (TEE) in patients with embolic stroke of undetermined source (ESUS) and compare it with other etiological stroke subtypes without known AF. Methods: This was a single-Centre, observational study involving comparison of echocardiographic parameters including LAA morphology and dimension in ESUS patients (group A; n ¼ 30) with other etiological stroke subtypes i.e., TOAST (Trial of Org 10172 in Acute Stroke Treatment) class I-IV without AF (group B; n ¼ 30). Results: Complex LAA morphology was predominant in group A (18 patients in group A versus 5 patients in group B, p-Value ¼ 0.001). Mean LAA orifice diameter (15.3 þ 3.5 mm in group A versus 17 þ 2.0 mm in group B, p-Value ¼ 0.027) and LAA depth were significantly lower in group A (28.4 þ 6.6 mm in group A versus 31.7 þ 4.3 mm in group B, p-Value ¼ 0.026). Out of these three parameters only complex LAA morphology was found to be independently associated with ESUS [OR ¼ 6.003, 95% CI {1.225e29.417}, p ¼ 0.027]. Conclusion: Complex LAA morphology is a predominant feature in ischemic stroke patients with ESUS and may contribute to an increased risk of stroke in these patients.

O Volume do Apêndice Atrial Esquerdo Prediz a Recorrência de Fibrilação Atrial após Ablação por Cateter de Radiofrequência: Uma Metanálise / Left Atrial Appendage Volume Predicts Atrial Fibrillation Recurrence after Radiofrequency Catheter Ablation: A Meta-Analysis

Resumo Fundamento A influência do volume do apêndice atrial esquerdo (VAAE) na recorrência de fibrilação atrial (FA) após ablação por cateter de radiofrequência permanece obscura. Objetivos Realizamos uma metanálise para avaliar se o VAAE é um preditor independente de recorrência de FA após ablação por cateter de radiofrequência. Métodos Os bancos de dados PubMed e Cochrane Library foram pesquisados até março de 2022 para identificar publicações avaliando o VAAE em associação com a recorrência de FA após ablação por cateter por radiofrequência. Foram encontrados 7 estudos que preencheram os critérios especificados de nossa análise. Usamos a Escala de Newcastle-Ottawa para avaliar a qualidade dos estudos. Os efeitos agrupados foram avaliados dependendo das diferenças médias padronizadas (DMPs) ou hazard ratios (HRs) com intervalos de confiança (ICs) de 95%. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados Um total de 1.017 pacientes de 7 estudos de coorte com um seguimento médio de 16,3 meses foram incluídos na metanálise. Dados de 6 estudos (943 indivíduos) comparando VAAE mostraram que o VAAE basal foi significativamente maior em pacientes com recorrência de FA em comparação com aqueles sem FA (DMP: −0,63; IC de 95%: −0,89 a −0,37; todos os valores de p < 0,05; I 2 = 62,6%). Além disso, maior VAAE foi independentemente associado a um risco significativamente maior de recorrência de FA após ablação por cateter de radiofrequência (HR: 1,10; IC de 95%: 1,02 a 1,18). Conclusões A metanálise mostrou que existe uma correlação significativa entre o VAAE e a recorrência de FA após ablação por cateter de radiofrequência, e o papel do VAAE em pacientes com FA não deve ser ignorado na prática clínica.

Abstract Background The influence of left atrial appendage volume (LAAV) on the recurrence of atrial fibrillation (AF) following radiofrequency catheter ablation remains unclear. Objectives We performed a meta-analysis to assess whether LAAV is an independent predictor of AF recurrence following radiofrequency catheter ablation. Methods The PubMed and the Cochrane Library databases were searched until March 2022 to identify publications evaluating LAAV in association with AF recurrence after radiofrequency catheter ablation. Seven studies that fulfilled the specified criteria of our analysis were found. We used the Newcastle-Ottawa Scale to evaluate the quality of the studies. The pooled effects were evaluated depending on standardized mean differences (SMDs) or hazard ratios (HRs) with 95% confidence intervals (CIs). P values < 0.05 were considered statistically significant. Results A total of 1017 patients from 7 cohort studies with a mean follow-up 16.3 months were included in the meta-analysis. Data from 6 studies (943 subjects) comparing LAAV showed that the baseline LAAV was significantly higher in patients with AF recurrence compared to those without AF (SMD: −0.63; 95% CI: −0.89 to −0,37; all p values < 0.05; I2= 62.6%). Moreover, higher LAAV was independently associated with a significantly higher risk of AF recurrence after radiofrequency catheter ablation (HR: 1.10; 95% CI: 1.02 to 1.18). Conclusions The meta-analysis showed that there is a significant correlation between LAAV and AF recurrence after radiofrequency catheter ablation, and the role of LAAV in AF patients should not be ignored in clinical practice.

The safety and efficiency of left atrial appendage closure combined delayed anticoagulant therapy in atrial fibrillation patients combined with cardiogenic stroke during anticoagulant therapy / 中国医师进修杂志

Objective:To assess the safety and efficiency of left atrial appendage closure (LAAC) combined delayed anticoagulant therapy in atrial fibrillation (AF) patients combined with cardiogenic stroke during anticoagulant therapy.Methods:Using prospective research methods, 35 AF patients combined with cardiogenic stroke during anticoagulant therapy from September 2020 to June 2022 in Xuanwu Hospital, Capital Medical University were selected. All patients were treated with LAAC and delayed anticoagulant therapy. The endpoints were the safety and efficacy of LAAC combined with delayed anticoagulant therapy. The primary endpoint of efficacy was the composite endpoint of postoperative death, myocardial infarction, hemorrhagic stroke and systemic embolism. The safety endpoint was major bleeding as defined by the International Society for Thrombosis and Hemostasis and clinically relevant non-major bleeding.Results:Among 35 patients, 21 were males and 14 were females; the age was (68.5 ± 9.3) years old; the CHA 2DS 2-VASc score was 5 (4, 6) scores; the time to the last stroke was 95 (42, 98) d; the National Institutes of Health stroke scale score at the time of stroke was 3 (1, 6) scores. All patients successfully completed LAAC without perioperative instrument-surface thrombosis, death, new stroke or bleeding events. Thirty-two patients continued oral anticoagulant therapy 45 d after LAAC. The patients were followed up for (12.6 ± 4.3) months, 1 patient experienced recurrent ischemic stroke, 2 patients endured mucosal bleeding, there were no adverse events such as all-cause death, cardiovascular death, systemic embolism and hemorrhagic stroke. Conclusions:The LAAC combined delayed anticoagulant therapy is efficient and safe in patients with AF. For AF patients combined with cardiogenic stroke during anticoagulant therapy, LAAC combined with delayed anticoagulation therapy may be considered to further prevent ischemic stroke events.

Atrial septal defect with atrial fibrillation treated by one-stop radiofrequency ablation and transthoracic closure under total endoscopy: A case report / 中国胸心血管外科临床杂志

@#Surgical treatment of atrial septal defect (ASD) mainly includes occlusion or repair under cardiopulmonary bypass. Surgical treatment of atrial fibrillation includes transcatheter radiofrequency ablation or Maze surgery under cardiopulmonary bypass. There are many treatments for ASD patients combined with atrial fibrillation, but each has its own advantages and disadvantages. We reported an ASD patient combined with atrial fibrillation treated by totally endoscopic "one-stop" radiofrequency ablation and simultaneous transthoracic ASD occlusion of atrial fibrillation, with good postoperative results.

Cierre de apéndice auricular en fibrilación auricular y alto riesgo de sangrado: serie de casos / Atrial appendage closure in atrial fibrillation and high risk of bleeding: case series

RESUMEN INTRODUCCIÓN: La fibrilación auricular aumenta 5 veces el riesgo de un ataque cerebrovascular de origen cardioembólico. La anticoagulación está indicada para prevención primaria y secundaria de embolismo cerebral. En pacientes con alto riesgo de sangrado no modificable se ha propuesto el cierre de apéndice auricular izquierdo como alternativa a la anticoagulación. MÉTODOS: Serie de casos retrospectiva de pacientes incluidos en el registro ReACTIVE entre los años 2019 y 2020 con diagnóstico de fibrilación auricular, puntaje de CHA2DS2-VASc ≥ 4, HAS BLED ≥ 3 y contraindicación de terapia anticoagulante a largo plazo. Se incluyeron variables demográficas, factores de riesgo, desenlace clínico usando la escala de Rankin modificado y se hizo seguimiento clínico a 3 meses después del procedimiento. RESULTADOS: Se incluyeron 6 pacientes, el 50 % de ellos mujeres, con mediana de edad de 80,8 ± 4,8 años. El 83,3 % presentó antecedente de sangrado mayor bajo consumo de anticoagulantes. En el seguimiento a 90 días, ningún paciente experimentó sangrado ni ataque cerebrovascular, un paciente murió por causas no cardiovasculares, en tanto que el 83,3 % de los pacientes tuvieron un Rankin modificado favorable (0-2). CONCLUSIONES: El cierre de apéndice auricular es una opción terapéutica en pacientes con fibrilación auricular y contraindicación para anticoagulación por alto riesgo de sangrado. Nuestra serie obtuvo resultados similares a los publicados a escala nacional a pesar de incluir pacientes con edad más avanzada. La conformación de equipos interdisciplinarios de corazón y cerebro es útil en la selección de pacientes para esta terapia.

ABSTRACT INTRODUCTION: Atrial fibrillation increases the risk of a cerebrovascular attack of cardioembolic source by 5 times. Anticoagulation is indicated for primary and secondary prevention of cerebral embolism. In patients at high risk of non-modifiable bleeding, closure of the left atrial appendage has been proposed as an alternative to anticoagulation. METHODS: Retrospective case series of patients included in the ReACTIVE registry between 2019 and 2020 with a diagnosis of atrial fibrillation, CHA2DS2-VASc score ≥ 4, HAS-BLED ≥ 3, and long-term anticoagulant therapy contraindication. Demographic variables, risk factors, and clinical outcomes were included using the modified Rankin scale, and clinical follow-up was done three months after the procedure. RESULTS: 6 patients were included, 50 % women, median age 80.8 ± 4.8 years. 83.3 % history of major bleeding under anticoagulant treatment. At the 90-day follow-up, no patient had a bleeding or cerebrovascular attack, one patient died from non-cardiovascular causes, and 83.3 % of the patients had a favorable modified Rankin (0-2). CONCLUSIONS: Atrial appendix closure is a therapeutic option in patients with atrial fibrillation and a contraindication for anticoagulation due to a high risk of bleeding. Our series obtained results like those published at the national level despite including older patients. The formation of interdisciplinary heart and brain teams is helpful in the selection of patients for this therapy.

Supramitral Membrane with Left Atrial Appendage Thrombus: A Rare Entity

A 4?year?old child with supramitralmembrane (SMM) causing severemitral stenosis (MS) was taken for excision of themembrane. Intraoperative transesophageal echocardiography showed a large thrombus in the left atrial appendage (LAA) in addition to SMM.The case underscores the importance of this extremely rare association and prompt therapy to prevent catastrophic consequences.

Apéndice cutáneo sacro asociado a lipoma del filum terminal y médula anclada: un caso de diagnóstico prenatal

Los disrafismos espinales cerrados tienen una prevalencia aún desconocida e involucran una gran variedad de formas. El lipoma del filum terminal es considerado dentro de los lipomas espinales y suele asociarse a médula anclada. Los estigmas cutáneos lumbosacros no siempre son indicadores de disrafismo espinal cerrado. Reportamos un caso de diagnóstico prenatal de apéndice cutáneo sacro con sospecha de médula anclada, confirmado al nacer como lipoma del filum terminal con médula anclada.

Closed spinal dysraphisms have a still unknown prevalence and involve a wide variety of forms. Lipoma of the filum terminale is considered within spinal lipomas and is usually associated with tethered medulla. Lumbosacral cutaneous stigmata are not always indicative of closed spinal dysraphism. We report a case of prenatal diagnosis of sacral cutaneous appendage with suspected tethered cord, confirmed at birth as lipoma of the filum terminale with tethered cord.

Prevalence and Echocardiographic Predictors of Left Atrial Appendage Inactivity in Patients of Mitral Stenosis

Background: Mitral stenosis (MS) is a common valvular heart disease. Thromboembolism is one of the most serious consequences of mitral stenosis, particularly when it is accompanied with atrial fibrillation (AF). When linked with Left atrial appendage inactivity (LAAI), patients with sinus rhythm (SR) are also at risk for this condition. In mitral stenosis, LAA inactivity determined by S-wave is an independent predictor of thromboembolism. The aim of the study was to evaluate the Prevalence and Echocardiographic Predictors of Left Atrial Appendage inactivity in patients of Mitral Stenosis.Material & Methods:Sixty MS patients were evaluated by transthoracic echocardiography (TTE) and all patients underwent transesophageal echocardiography (TEE). The annular systolic (S-wave) and diastolic (Em- and Am-waves) velocities were recorded by tissue Doppler imaging (TDI). LAA inactivity was defined as LAA emptying velocity <25 cm/second determined by pulse wave Doppler at the junction of LA & LAA (TEE). Patients were divided into three groups; group A I (n = 18). Sinus rhythm (SR) and LAA emptying velocity ?25 cm/sec, group A II (n -22): SR and LAA emptying velocity <25cm/sec and group B (n = 20): atrial fibrillation.Results:Thrombus was detected in 14 patients and spontaneous echo contrast (SEC) was detected in 43 patients. Both S-wave and peak LAA emptying velocities were decreasing, while SEC frequency and density were increasing from group A to group B. There was a positive correlation between LAA emptying vs. S-wave and LAA emptying vs. Am velocities (p < 0.001, r= 0.708 and p<0.001, r=0.495). Multivariate regression analysis showed that only S-wave is the independent predictor of inactive LAA (p = 0.001, odds ratio = 0.133, 95% Cl =0.032-0.556). In patients with SR, the cutoff value of S-wave was 10 cm/sec for the prediction of the presence of inactive LAA (sensitivity: 92.3%, specificity: 95.3%).Conclusions:In individuals with severe mitral stenosis in sinus rhythm, there is a significant prevalence of left atrial appendage inactivity. The mean pressure gradient across the mitral valve, as well as S-wave are independent predictors of left atrial appendage inactivity. Inactivity of the left atrial appendage is an independent predictor of left atrial/left atrial appendage smoke and associated thrombus.

In vivo reflectance confocal microscopic findings in a case of trichofolliculoma

Abstract Trichofolliculoma is a rare follicular hamartoma whose dermoscopic features have been scarcely reported. On the other hand, reflectance confocal microscopy features have not been described yet. In the present study, the authors report reflectance confocal microscopy features in a case of trichofolliculoma as squamous hyperplasia forming irregular finger-like protrusions around the hair follicle and papillomatous hyperplasia of the hair follicle epithelium, which correlated with histopathology. This case suggests that reflectance confocal microscopy may help incorrect in vivo diagnosis of trichofolliculoma in cases difficult to diagnose by morphology and dermoscopy.

Cierre percutáneo de orejuela en paciente con antecedente de cierre percutáneo de comunicación interauricular / Left atrial appendage closure in a patient with prior atrial septal defect occlusion

Resumen La fibrilación auricular es la arritmia más prevalente en la práctica clínica, y se asocia con una morbimortalidad significativa, la cual, en parte, se explica por el riesgo de fenómenos embólicos. En la actualidad, el uso de anticoagulantes es el estándar de manejo en aquellos pacientes con riesgo embólico significativo (dado por un puntaje ≥ 2 en la escala CHA2DS2Vasc). Sin embargo, algunos pacientes tienen contraindicaciones que impiden recibir este tipo de tratamiento a largo plazo, en cuyo caso se considera el cierre percutáneo de la orejuela como medida para la disminución del riesgo de embolia. Al requerir una punción transeptal, la presencia de dispositivos de cierre de defectos del septo interauricular dificulta el procedimiento de manera significativa. Se presenta el caso de una paciente con contraindicación absoluta para recibir anticoagulantes debido a sangrado gastrointestinal y antecedente de cierre percutáneo de comunicación interauricular sometida a cierre percutáneo de orejuela como alternativa terapéutica a la anticoagulación.

Abstract Atrial fibrillation is the most prevalent arrythmia in clinical practice, associated with a significant morbimortality explained, in part, by the high risk of embolic phenomena. The use of anticoagulation is the standard of care in those patients with increased embolic risk (given by a score ≥ 2 in the CHA2DS2Vasc scale). However, some patients have contraindications to receiving this treatment long-term, in which case percutaneous left atrial appendage occlusion can be considered as a means of decreasing their embolic risk. Because the procedure requires transeptal puncture, the presence of devices for atrial septal defect closure can difficult the technique. We present the case of a patient with absolute contraindication to anticoagulation therapy given gastrointestinal bleeding, with history of percutaneous closure of interauricular communication, who was treated with percutaneous left atrial appendage occlusion as an alternative to oral anticoagulants.

Oclusão do Apêndice Atrial Esquerdo com a Prótese Lambre: Experiência Multicêntrica Inicial no Brasil / Left Atrial Appendage Closure with the LAmbre Device - Initial Multicentre Experience in Brazil

Resumo Fundamento A oclusão do apêndice atrial esquerdo (AAE) tem se mostrado uma alternativa à terapia de anticoagulação oral (ACO) para prevenção de acidente vascular cerebral (AVC) em pacientes com fibrilação atrial não valvar (FANV). Objetivos Descrever os primeiros resultados de uma experiência inicial multicêntrica no Brasil e investigar a viabilidade, a segurança e a eficácia da oclusão do AAE com o novo dispositivo LAmbre. Métodos Coletamos dados do procedimento e do acompanhamento de 51 pacientes consecutivos com FANV, restrições para ACO em longo prazo e com anatomia adequada, submetidos à oclusão do AAE com o dispositivo LAmbre em 18 centros no Brasil. Indicações para o procedimento foram: sangramento importante em pacientes recebendo ACO (47,1%), AVC ou trombo persistente no AAE apesar de ACO adequada (27.5%), sangramento e AVC (17.6%), outras contraindicações clínicas apara ACO (5,9%), e escolha do paciente devido à prática esportiva (1,9%). Resultados Foram estudados 25 homens (49%) e 26 mulheres (51%), com idade média de 76±7,7 anos, escore CHA2DS2-VASc médio de 4,6± 1,7 e escore HAS-BLED médio de 3.4± 1,1. A taxa de sucesso do procedimento foi de 100%. As complicações imediatas relacionadas ao procedimento foram derrame pericárdico em dois pacientes, e embolização do dispositivo em um caso. Não foram observados shunts residuais > 5mm. Shunts < 5mm foram detectados em quatro pacientes por Doppler colorido ao final do procedimento. Após um período médio de acompanhamento de 18 meses ± 12 meses, não foram observados óbito, AVC ou complicações maiores. Conclusão A oclusão do AAE com o dispositivo LAmbre foi segura e eficaz nesta pequena série de casos. Apesar desses resultados iniciais encorajadores, dado o pequeno número de casos, serão necessários mais estudos com um maior período de acompanhamento.

Abstract Background Left atrial appendage (LAA) closure has been an alternative to oral anticoagulation (OAC) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). Objectives To report the first results of an initial multicenter experience in Brazil and to investigate the feasibility, safety, and efficacy of LAA closure with the new LAmbre device. Methods We collected procedural and follow-up data of 51 consecutive patients with non-valvular atrial fibrillation, restrictions for long-term OAC and suitable anatomy that underwent LAA closure with the LAmbre device in 18 centers in Brazil. Procedural indications were significant bleeding under OAC (47.1%), stroke or persistent LAA thrombus despite OAC (27.5%), bleeding plus stroke (17.6%), other clinical contraindications for OAC (5.9%), and patient's choice due to sports practice (1.9%). Results Twenty-five men (49%) and 26 women (51%), with a mean age of 76±7.7 years, mean CHA2DS2-VASc score of 4.6± 1.7 and mean HAS-BLED score of 3.4± 1.1 were studied. Procedural success rate was 100%. Procedure-related immediate complications were pericardial effusion in two patients, and immediate device embolization in one case. No large residual shunts (> 5 mm) were observed, and small shunts (<5mm) were detected in four patients by color Doppler at the end of the procedure. After a mean follow-up of 18 ± 12 months, there were no deaths, strokes nor any other major complications. Conclusion LAA occlusion with the LAmbre device was safe and effective in this small case series. Despite these encouraging initial results, the small number of cases warrants further studies with longer-term follow-up.

Intraoperative echocardiographic contrast opacifies the left atrial appendage and assists in surgical exclusion

Surgical exclusion of the left atrial appendage (LAA) for stroke prevention in atrial fibrillation is frequently incomplete and remains to be optimized. We present a man who did not tolerate anticoagulant and failed percutaneous occlusion. Intraoperative echocardiographic contrast was used to assist surgical exclusion. Follow?up showed a persistent occlusion.

Hidradenoma papilífero de la vulva con componente de carcinoma in situ: reporte de caso y revisión de la bibliografía / Papilliferous hidradenoma of the vulva with carcinoma in situ component: case report and literature review

Resumen ANTECEDENTES: El cáncer de vulva es relativamente raro, representa menos del 1% de los tumores malignos de la mujer; su incidencia aumenta con la edad. La variedad más frecuente es el carcinoma escamoso (80 al 90%), seguido del melanoma. En este reporte se revisa un carcinoma de origen glandular, como el hidradenoma papilífero del tipo glándula mamaria (mammary-like) de la vulva. CASO CLÍNICO: Paciente de 50 años, con una lesión papular en la vulva de dos años de evolución, con crecimiento lento y progresivo, ocasional sensación de masa y dolor, con colposcopia negativa, sin antecedentes de patología mamaria y con una biopsia previa que reportó hidradenoma papilífero vulvar. Se trató con resección completa de la lesión, con anestesia regional, con bordes libres, no se identificó algún componente infiltrante. En la actualidad permanece sin evidencia de recaída ni requerimiento de tratamientos adicionales durante el seguimiento. CONCLUSIÓN: El hidradenoma papilífero es una lesión benigna, poco frecuente, relacionada con las glándulas anogenitales de tipo mammary-like, con buen pronóstico. El tratamiento recomendado es la escisión quirúrgica, que casi siempre es curativa.

Abstract BACKGROUND: Vulvar cancer is relatively rare, representing less than 1% of malignant tumors in women; its incidence increases with age. The most frequent variety is squamous cell carcinoma (80 to 90%), followed by melanoma. In this report we review a carcinoma of glandular origin, such as papilliferous hydradenoma of the vulva of the mammary gland (mammary-like) type. CLINICAL CASE: We present a 50-year-old patient with 2 years evolution of a papular lesion on the vulva with slow and progressive growth, intermitent sensation of mass and pain, with negative colposcopy, no history of breast pathology and with a previous biopsy that reported vulvar papilliferous hydradenoma. She was treated with complete resection of the lesion under regional anesthesia, with free margins, without identifying an infiltrating component and currently without evidence of relapse or requirement of additional treatments. CONCLUSION: Papilliferous hidradenoma is a rare benign lesion related to the mammary-like anogenital glands, with a good prognosis and its recommended treatment is surgical excision, which is generally curative.

Cistoadenoma volumoso associado a teratoma ovariano maduro, com evolução para pseudomixoma peritoneal: relato de caso / Giant cystadenoma associated with mature ovarian teratoma with progression to pseudomyxoma peritonei: a case report

Massas anexiais representam grande desafio diagnóstico, devido a seu caráter geralmente assintomático¹. Traz-se caso peculiar de paciente que evoluiu com sintomas exuberantes de rápida evolução, situação característica de cistoadenomas, tumores benignos de origem epitelial²,³. Realizada laparotomia, com achados macroscópicos que revelaram conteúdo mucinoso e presença de pelos e neovascularização em seu interior. O anatomopatológico confirmou o diagnóstico de cistoadenoma associado a teratoma ovariano, sendo assim considerado um tumor de colisão ovariana.
