En el 51,6 % de los casos se diagnosticaron neoplasias, de las cuales el 47,8 % eran primarias de pulmón, siendo el adenocarcinoma el subtipo más común. Las enfermedades benignas no tumorales representaron el 48,3 % de los casos y la causa más frecuente fueron las infecciones, dentro de las que se incluyeron 17 casos de tuberculosis pulmonar. La técnica más frecuente fue la cirugía toracoscópica video asistida (82,6 %). Presentaron un porcentaje de reintervención del 5,8 %, 10,6 % de complicaciones severas y una mortalidad hospitalaria del 4,3 %. Conclusión. La población evaluada muestra una carga alta de comorbilidades y riesgo operatorio elevado; de forma consecuente, al compararla con otras series internacionales, se encontró un porcentaje mayor de complicaciones perioperatorias y mortalidad.

Introduction. The pulmonary lobectomies is one of the most common procedures in thoracic surgery in Colombia and worldwide. The objective of this study is to provide information on the clinical behavior of individuals who underwent this type of surgeries. Methods. Retrospective observational study at a University Hospital in Cali, Colombia, including all individuals who had pulmonary lobectomies, between the years 2010 to 2020 for benign and malignant causes. The information was extracted from the institutional registry of thoracic surgery, obtaining demographic, clinical and pathological data. Results. The clinical records of 207 individuals were evaluated, 55.5% were women, the average age was 58 years, and 41% had a history of smoking. Of these cases, 51.6% were diagnosed with neoplasms, of which 47.8% were primary lung neoplasms, with adenocarcinoma being the most common subtype. As for benign diseases, they represented 48.3% of the cases and the most frequent cause was infections, including 17 cases of pulmonary tuberculosis. The most frequent technique was video-assisted thoracoscopic surgery in 82.6%, with a reoperation rate of 5.8%, up to 10.6% of severe complications, a median hospital stay of 6 days, and a hospital mortality of 4.3%.Conclusion. The population evaluated shows a high burden of comorbidities and high operative risk; consequently, when compared with other international series, it shows a higher percentage of perioperative complications, hospital stay, and mortality.

Paciente con quistes pulmonares y diagnóstico de coinfección con tuberculosis e hidatidosis: reporte de un caso pediátrico / Patient with pulmonary cysts and diagnosis of co-infection with tuberculosis and hydatidosis. Pediatric cases report

Existen numerosas entidades en la población pediátrica que pueden presentarse en forma de quistes o como lesiones de similares características. De estas patologías, las infecciosas son las más frecuentes. Se presenta el caso de una paciente oriunda de Bolivia con migración reciente a la Argentina que presentó una coinfección con tuberculosis e hidatidosis pulmonar. Ambas infecciones se pueden presentar con signos y síntomas similares y, aunque la asociación citada es poco frecuente en la bibliografía, ciertos mecanismos inmunitarios podrían intervenir en la coinfección de parásitos helmintos y micobacterias. Ambas patologías son infecciones prevalentes en nuestra región y deben ser tenidas en cuenta entre los diagnósticos diferenciales ante pacientes con imágenes quísticas o cavitarias pulmonares.

Numerous entities in the pediatric population can present in the form of cysts or as lesions with similar characteristics. Of the pathologies that can cause these images in children, infectious diseases are the most frequent. We present the case of a native of Bolivia with recent immigration to Argentina who presented a pulmonary co-infection with tuberculosis and hydatidosis. Both infections can present with similar signs and symptoms and although this association is rarely reported in the literature, certain immunological mechanisms could intervene in the causal association of co-infection between helminth parasites and mycobacteria. Both pathologies are very prevalent infections in our region and should be taken into account among the differential diagnoses in patients with cystic or cavitary pulmonary diseases.

Método JaPer. Una nueva estrategia para mejorar la capacidad inspiratoria. Ensayo Clínico Aleatorizado / JaPer Method. A new strategy to improve inspiratory capacity. Randomized clinical trial

Introducción: las enfermedades pulmonares pueden generar hospitalizaciones, estancias prolongadas, complicaciones e inclusive la muerte. Estas enfermedades repercuten negativamente en la capacidad inspiratoria y en la calidad de vida. Por lo tanto, el presente artículo pretende analizar los efectos del Método JaPer sobre la capacidad inspiratoria de los pacientes hospitalizados. Material y métodos: ensayo clínico aleatorizado inicialmente con 653 pacientes hospitalizados que pasó a 587 distribuidos en 2 grupos (Grupo experimental-GE: Método JaPer vs Grupo control-GC: uso convencional de inspirómetro volumétrico). Se determinó la capacidad inspiratoria máxima, caminata de los 6 minutos, antropometría y un cuestionario creado por los autores. Se aplicó un programa de entrenamiento de 2 semanas de 3 sesiones por día. Al GE se le aplicó el Método Japer con protocolo estandarizado para hacer ejercicios entre el 50 y el 80 % de la capacidad inspiratoria máxima del paciente y a los pacientes del GC se les realizó incentivo inspiratorio a inspiración máxima. Resultados: 587 pacientes (F:300 vs M:287) con edad promedio de 53.61±14.24 años, entre los cuales el 9.88 % tenía bajo peso, 17.89 % peso normal y el 27.26 % y 44.97 % sobrepeso y obesidad, respectivamente. Todos los participantes realizaron una caminata de 6 minutos para determinar los metros recorridos (GE: 387.70±47.59 vs GC: 371.30±49.10), velocidad (GE: 64.62±7.93 vs GC: 61.88±8.18) y el Vo2 estimado (GE: 9.96±0.79 vs GC: 9.69±0.82). Todas las variables y la capacidad inspiratoria máxima (GE: 1708.54±707.84 vs GC: 1448.83±692.79) determinaron pre y post entrenamiento. Conclusiones: el Método JaPer obtuvó mejores resultados en todas las variables evaluadas con diferencia significativa (p= <0.05) frente al grupo control, resaltando que la capacidad inspiratoria máxima aumentó en ambos grupos (GE:44 % vs GC:28 %; p= <0.05).

Introduction: Pulmonary diseases can generate hospitalizations, prolonged stays, complications and even death. These diseases have a negative impact on inspiratory capacity and quality of life. Therefore, this paper tries to analyze the effects of the JaPer method on the inspiratory capacity of hospitalized patients. Materials and methods: Randomized clinical trial initially with 653 patients, which went on to 587 hospitalized patients distributed in 2 groups (Experimental group: JaPer Method vs. Control group: Conventional use of volumetric inspirometer). Maximum inspiratory capacity, 6-minute walk, anthropometry, and a questionnaire created by the authors were determined. A 2-week training program of 3 sessions per day was applied. The GE applied the Japer Method with a standardized protocol to exercise between 50 and 80% of the patient's maximum inspiratory capacity, and the CG underwent inspiratory incentive at maximum inspiration. Results: 587 patients (F:300 vs M:287) with a mean age of 53.61±14.24 years and 9.88% of the population were underweight, 17.89% normal weight and 27.26% and 44.97% overweight and obese, respectively. All participants performed a 6-minute walk to determine meters traveled (GE: 387.70±47.59 vs CG: 371.30±49.10), speed (GE: 64.62±7.93 vs CG: 61.88±8.18) and estimated VO2 (GE: 9.96 ±0.79 vs CG: 9.69±0.82). All variables and maximal inspiratory capacity (GE: 1708.54±707.84 vs CG: 1448.83±692.79) were determined before and after training. Conclusions: The JaPer method obtained better results in all the variables evaluated with a significant difference (p=<0.05) compared to the control group. Highlighting that the maximum inspiratory capacity increased in both groups (GE:44% vs CG:28%; p=<0.05).

Resumen Introducción: El tratamiento de elección del Quiste Hidatídico Pulmonar (QHP) es la resección quirúrgica. Actualmente, existe controversia sobre la superioridad de la cirugía con capitonaje (CC) versus la cirugía sin capitonaje (SC). Objetivo: Comparar los resultados de la cirugía conservadora CC y SC mediante Propensity Score Matching (PSM). Materiales y Método: Se realizó un estudio analítico retrospectivo de los pacientes con QHP tratados quirúrgicamente en el Hospital Guillermo Grant Benavente, Concepción, Chile; entre enero-1995 y diciembre-2018. Se realizó un PSM con una relación 1:1 entre los pacientes operados con la técnica CC y SC. Posterior al PSM se balancearon las características basales. Resultados: Total 205 episodios de QHP en el período. Se realizó cirugía conservadora en 165 casos, 101 CC y 64 SC. Posterior al emparejamiento se obtuvieron 53 pacientes operados CC y 53 SC. No se observaron diferencias significativas en la presencia de fuga aérea persistente (CC = 9,4%; SC = 11,3%, p 0,75), empiema (CC = 3,8%; SC = 0%, p 0,49), días con pleurotomía (CC = 9,1 ± 8,9; SC 10,1 ± 10,7, p 0,39, mediana 6 versus 6 días, respectivamente), ni días de estadía posoperatoria (CC = 10,4 ± 9,0; SC = 11,7 ± 11,9, p 0,22, mediana 7 versus 7 días, respectivamente). Conclusiones: La cirugía SC demostró resultados comparables a la técnica CC en el tratamiento quirúrgico conservador del QHP.

Cigarros eletrônicos e suas consequências histopatológicas relacionadas à doenças pulmonares / E-cigarettes and histopathological consequences related to lung diseases

O cigarro eletrônico surgiu como uma tentativa para minimizar a dependência ao uso de tabaco, entretanto, engloba controvérsias e dúvidas acerca das reais implicações para o organismo humano. Diante disso, o presente estudo tem como objetivo realizar uma revisão da literatura a fim de relacionar o uso de cigarro eletrônico com suas consequências para os humanos. Os estudos analisados relatam experimentos in vitro e in vivo em camundongos, demonstrando menor concentração de poluentes e nocividades no cigarro eletrônico comparado ao convencional, porém, seu potencial efeito maléfico está relacionado à composição do e-líquido, à maneira do uso e à variedade de aromas presentes nos produtos. Além disso, foram verificadas lesões celulares, hiperreatividade das vias aéreas, liberação de citocinas ­ IL-8, IL-10 e TNF, redução da ação antimicrobiana de queratinócitos e potencial apoptose nas células alveolares. Foi observado também um aumento em até cinco vezes da concentração de carboxihemoglobina em comparação ao cigarro comum e um aumento na auto renovação de células de adenocarcinoma pulmonar de células não pequenas, devido à expressão de SOX2. Observa-se também que em casos de DPOC, o cigarro eletrônico não apresenta agravamentos na fisiologia respiratória, contrapondo outras ocorrências como asma, pneumonia, câncer de pulmão e doenças infecciosas que podem ser ocasionadas ou exacerbadas pelo seu uso. Contudo, pelo curto prazo de observação de seus efeitos, não é possível determinar com precisão a segurança dos cigarros eletrônicos, dessa forma, faz-se necessário que mais pesquisas longitudinais sejam desenvolvidas, auxiliando, assim, na construção de evidências sobre a segurança dos cigarros eletrônicos e na regulamentação futura do produto.

Electronic cigarettes emerged as an attempt to minimize tobacco dependence. However, its use is surrounded by controversies and doubts about the real implications for the human organism. Therefore, this study aims at performing a review of the most recent literature to corelate the use of e-cigarettes with their consequences for the human body. The analyzed studies relate in vitro and in vivo experiments on mice, demonstrating lower concentration of pollutants and harmfulness in the electronic cigarette than in conventional cigarettes. However, its potential harmful effect is related to the composition of the e-liquid, in its use and in the variety of aromas in the products. In addition, cellular lesions, airway hyperreactivity, release of IL-8, IL-10 and TNF cytokines could be observed, as well as reduced keratinocyte antimicrobial action and potential apoptosis in alveolar cells. An increase of up to five-fold the concentration of carboxyhemoglobin in comparison to ordinary cigarettes and an increase in self-renewal of non-small pulmonary adenocarcinoma cells due to the expression of SOX2 have also been related. It could also be observed that in COPD cases, e-cigarettes do not present worsening in respiratory physiology, which contrasts with other occurrences such as asthma, pneumonia, lung cancer, and infectious diseases that can be caused or exacerbated by its use. However, due to the short term of observation of the effects, the safety of e-cigarettes could not be accurately determined, thus, the need for further longitudinal research is necessary, which could be used to help build evidence about the safety of e-cigarettes and also to create future regulation of the product.

O impacto da COVID-19 na população idosa com doença pulmonar crônica não transmissível / The impact of COVID-19 on the elderly population with non-communicable chronic lung disease

Introdução: Envelhecer resulta em transformações biológicas que afetam os indivíduos de maneira heterogênea. A maioria dos sistemas orgânicos experimenta redução em suas funções motoras e cognitivas, interferindo na capacidade de adaptação frente a agentes estressores. Na pneumonia pelo SARS-CoV2, evidenciaram-se implicações da função pulmonar em idosos com doenças pulmonares crônicas. Objetivo: Investigar as evidências científicas sobre implicações clínicas da COVID-19 em indivíduos idosos com doença pulmonar crônica não transmissível. Métodos: revisão integrativa realizada em novembro de 2020 nas bases de dados CINAHL (Cumulative Index to Nursing and Allied Health Literature), Embase, Scopus, Medline/Pubmed (via National Library of Medicine) e Web of Science, utilizando-se os descritores "COVID-19", "SARS-CoV2 infection", "aged", "chronic pulmonar obstructive disease", "non-communicable diseases" e operadores booleanos AND e OR. Foram incluídos textos científicos originais, a exemplo de artigos disponibilizados na íntegra, sobre a COVID-19 em idosos com Doenças Respiratórias Crônicas Não Transmissíveis. Resultados: Idosos com comorbidades estão propensos a complicações durante a infecção por COVID-19, com altas taxas de mortalidade e alterações tomográficas atípicas. Conclusão: A forma grave da COVID-19 e a elevada mortalidade em idosos podem ser atribuídas à alta comorbidade, prevalência de demência e síndromes geriátricas. (AU)

Intercambio plasmático terapéutico por plasmafiltración: experiencia de 11 años de un centro / Therapeutic plasma exchange: experience in 102 patients

BACKGROUND: Therapeutic Plasma Exchange (TPE) is a procedure in which plasma and harmful macromolecules are separated from the rest of the blood components by centrifugation or filtration through membranes and are replaced with solutions with albumin and/or plasma. AIM: To communicate our experience using TPE by filtration. MATERIAL AND METHODS: Review of records of 655 TPE sessions performed in 102 patients aged 50 ± 18 years (64% women). The requirement of renal replacement therapy (RRT) and seven days and one year mortality were recorded. RESULTS: Forty five percent of patients had hypertension or diabetes. The main indications for TPE were pulmonary-renal syndrome (PRS) (62%) and antibody mediated graft rejection (29%), followed by neurological diseases (36%). Fifteen percent of patients required RRT for one year. Mortality at seven days and one year was 20 and 30%, respectively. Out of the total of deaths associated with kidney diseases, 88% corresponded to PRS and ANCA vasculitis. The main complications were thrombocytopenia in 41%, hypocalcemia in 18%, and hypotension in 16%. CONCLUSIONS: In our experience, TPE by filtration is a safe technique, with mild and preventable complications. Despite this, the reported mortality is high, which reflects the severity of the diseases that motivated the indication for TPE.

Perinatal Outcomes after Fetal Endoscopic Tracheal Occlusion for Isolated Congenital Diaphragmatic Hernia: Rapid Review / Resultados perinatais após oclusão traqueal endoscópica fetal por hérnia diafragmática congênita isolada: Revisão rápida

Abstract Objective To compare the perinatal outcomes of fetuses with isolated congenital diaphragmatic hernia after fetal endoscopic tracheal occlusion (FETO) and antenatal expectant management. Data sources In this rapid review, searches were conducted in the MEDLINE, PMC, EMBASE and CENTRAL databases between August 10th and September 4th, 2020. Randomized controlled trials (RCTs), quasi-RCTs or cluster-RCTs published in English in the past ten years were included. Study selection We retrieved 203 publications; 180 studies were screened by abstract. Full-text selection was performed for eight studies, and 1 single center RCTmet the inclusion criteria (41 randomized women; 20 in the FETO group, and 21 in the control group). Data collection Data collection was performed independently, by both authors, in two steps (title and abstract and full-text reading). Data synthesis There were no cases of maternal mortality. The mean gestational age at delivery was of 35.6±2.4 weeks in the intervention group, and of 37.4±1.9 weeks among the controls (p<0.01). Survival until 6 months of age was reported in 50% of the intervention group, and in 5.8% of the controls (p<0.01; relative risk: 10.5; 95% confidence interval [95%CI]: 1.5-74.7). Severe postnatal pulmonary hypertension was found in 50% of the infants in the intervention group, and in 85.7% of controls (p=0.02; relative risk: 0.6; 95%CI: 0.4-0.9). An analysis of the study indicated some concerns of risk of bias. The quality of evidence was considered moderate to low. Conclusion Current evidence is limited but suggests that FETO may be an effective intervention to improve perinatal outcomes.

Criptococosis diseminada en paciente inmunocompetente imitando un cáncer de pulmón metastásico / Disseminated cryptococcosis in an immunocompetent patient imitating metastatic lung cancer

El cáncer de pulmón es la principal causa de muerte en el mundo por cáncer, y en Colombia es la segunda. Su pronóstico es pobre cuando se ha documentado enfermedad metastásica en el sistema nervioso central. El diagnóstico se basa en el resultado definitivo de patología. Aunque los hallazgos imagenológicos pueden ser muy sugestivos de malignidad, hay reportes de otras enfermedades que pueden imitar cáncer, tales como infecciones o tumores benignos, los cuales pueden llevar a adoptar conductas terapéuticas inapropiadas. Las infecciones fúngicas como las producidas por Criptococcus neoformans, son capaces de generar lesiones que pueden imitar neoplasias. El objetivo de esta publicación es reportar el caso de un hombre a quien inicialmente se le sospechó un carcinoma pulmonar metastásico al sistema nervioso central, y finalmente se le diagnosticó una criptococosis diseminada posterior a su fallecimiento

Lung cancer is the leading cause of death from cancer in the world and the second in Colombia, its prognosis is bad when the diagnosis of metastatic disease in the central nervous system is documented. The diagnosis is based on the definitive pathologic result. Although the imaging findings can be highly suggestive of malignancy, there are reports of other conditions that can mimic lung cancer, such as infections or benign tumors, which can lead to inappropriate treatment. Fungal infections such as those caused by Criptococcus neoformans are capable of generating lesions that can mimic neoplasms. The objective of this article is to report the case of a man who was initially diagnosed with metastatic lung carcinoma to the central nervous system, and was finally diagnosed with disseminated cryptococcosis after his death

Epidemiological profile and follow-up of patients with pulmonary disease by non-tuberculous mycobacteria in Baixada Santista area, São Paulo

ABSTRACT Objective To present the frequency and species diversity of non-tuberculous mycobacteria, estimate the prevalence of non-tuberculous mycobacterial pulmonary disease, describe the epidemiological profile, and determine the follow-up of patients with non-tuberculous mycobacterial pulmonary disease living in a region with a high burden of tuberculosis. Methods This a retrospective cohort observational study using data records obtained from the Instituto Adolfo Lutz - Santos and from the São Paulo Sistema de Vigilância de Tuberculose do Estado de São Paulo in the period between 2000 and 2009. The studied variables were: socio-demographic characteristics, current and past history of tuberculosis, aspects related to diagnosis, and treatment and associated diseases. Results We included 319 non-tuberculous mycobacteria isolates in the study, corresponding to 257 patients. The species Mycobacterium kansasii (28.5%) and Mycobacterium fortuitum (16.6%) presented the higher occurrence. In 10.9% (24) of the patients, there was a criterion for confirming a case of pulmonary disease due to non-tuberculous mycobacteria. In relation to gender and age, male and individuals over 50 years old were the most frequent. Considering the confirmed cases, 47.8% had a past history of tuberculosis. Conclusion The lack of information about the cases is evident, since pulmonary disease due to non-tuberculous mycobacteria is not mandatory. The therapeutic regimen according to the identified species is fundamental for success in combating the infections caused by non-tuberculous mycobacteria. Besides that, information about the regional epidemiology of pulmonary disease caused by non-tuberculous mycobacteria and the search for associations with other comorbidities are important to establish the correct treatment. In order to improve surveillance of pulmonary diseases by non-tuberculous mycobacteria, we suggest the implantation of a sentinel surveillance and of population-based studies.

Apport du test expert MTBRIF dans le diagnostic de la tuberculose toute forme à Saint-Louis / contribution of the Xpert MTB / Rif test in the diagnosis of tuberculosis of any form in Saint-Louis

Introduction: le test Xpert MTB/RIF présente un double avantage d'une part le diagnostic rapide des cas mêmes difficiles par la technique standard de l'examen direct à la microscopie et d'autre part par la détection de la résistance à la rifampicine. Notre objectif était de déterminer l'apport du test Xpert dans le diagnostic de la tuberculose toutes formes confondues. Matériels et méthode : étude transversale, descriptive à collecte rétrospective menée dans le service de Pneumophtisiologie de CHRU de Saint-Louis. Tous les cas suspects de tuberculose qui avaient bénéficié d'un test Xpert de 2018 à 2020avec un dossier médical accessible et exploitable ont été inclus. Les paramètres étudiés étaient les données sociodémographiques, cliniques et biologiques. Résultats : Nous avions colligés 524dossiers de malades avec un sex-ratio de 1,3. L'âge moyen des patients était de 37 ans+/-15 ans. Il y'avait 285 prélèvements positifs au GeneXpert dont 224 d'origine pulmonaire et 61d'origine extra pulmonaire. Le nombre d'échantillons résistants à la rifampicine était de cinq, tous d'origine respiratoire. Conclusion: le test Xpert est une nouvelle technique moléculaire recommandée par l'OMS dans le diagnostic de la tuberculose pulmonaire. Toutefois il doit être évaluer dans le diagnostic de la tuberculose extra pulmonaire

Introduction: The Xpert MTB / RIF assay has a dual advantage on the one hand, the rapid diagnosis of even difficult cases by the standard technique of direct microscopic examination and on the other hand by the detection of resistance to rifampicin. Our objective was to determine the contribution of the Xpert test in the diagnosis of tuberculosis of all forms. Materials and method: retrospective, descriptive and analytical study carried out in the Pneumophtisiology department of the CHRU of Saint-Louis. All suspected tuberculosis cases who had received an Xpert test from 2018 to 2020 were included. The parameters studied were socio-demographic, clinical and biological data. Results: 524 patient records included in the study with a sex ratio of 1.3. The mean age of the patients was 37 +/-15 years. There were 285 positive GeneXpert samples, of which 224 were of pulmonary origin and 61 of extra-pulmonary origin. The number of rifampicin resistant samples was five, all of respiratory origin. Conclusion: the Xpert test is a new molecular technique recommended by the WHO in the diagnosis of pulmonary tuberculosis

Efeitos agudos dos exercícios respiratórios, Threshold PEP™ e Powerbreathe® em pacientes com derrame pleural, no pós-procedimento de drenagem torácica / Acute effects of breathing exercises, Threshold PEP™ and Powerbreathe® in patients with pleural effect, in the post-thoracic drainage procedure

Introdução: O derrame pleural modifica as capacidades pulmonares, provocando distúrbio ventilatório restritivo. As terapias respiratórias evitam a progressão e tratam a restrição de volumes pulmonares. Objetivo: Comparar o efeito agudo de três recursos fisioterapêuticos em pacientes com derrame pleural após procedimento de drenagem torácica. Métodos: Estudo experimental, randomizado e prospectivo, realizado com 60 pacientes com derrame pleural, todos hospitalizados. A amostra foi dividida em 3 grupos com 20 pacientes, cada grupo recebeu uma terapia respiratória: exercícios respiratórios, Threshold PEP™ ou Powerbreathe®. Para avaliar a função pulmonar foram utilizados, a espirometria, a manovacuometria e o peak flow. Os atendimentos foram diários, seguiu-se o protocolo de 4 séries de 15 repetições. Análise estatística: aplicou-se os testes qui-quadrado de Pearson, Shapiro-Wilk, Friedman, Wilcoxon e correlação de Spearman. Para todos os testes considerou-se o nível de significância de 5%. Resultados: Os exercícios respiratórios resultaram em diferenças significativas na capacidade vital forçada (CVF), antes 1,66±0,60 e depois 1,84±0,50 (p=0,01), no volume expiratório forçado no primeiro segundo (VEF1), antes 1,25±0,46 e depois 1,57±0,52 (p=0,01), enquanto o grupo tratado com Threshold PEP™ a diferença significativa foi apenas na CVF, antes 1,49±0,78 e depois 1,78±0,85 (p=0,04). Em relação à força muscular respiratória, nenhuma das terapias resultou em diferença significativa na PImax e PEmax. Conclusão: O protocolo com exercícios respiratórios demonstrou superioridade na função pulmonar quando comparado com o Threshold PEP™ e Powerbreath®, tornando-se mais indicado no manejo de pacientes com derrame pleural após drenagem torácica.

A scoping study of pulmonary paracoccidioidomycosis: severity classification based on radiographic and tomographic evaluation

The lungs have great importance in patients with paracoccidioidomycosis since they are the portal of entry for the infecting fungi, the site of quiescent foci, and one of the most frequently affected organs. Although they have been the subject of many studies with different approaches, the severity classification of the pulmonary involvement, using imaging procedures, has not been carried out yet. This study aimed to classify the active and the residual pulmonary damage using radiographic and tomographic evaluations, according to the area involved and types of lesions.
