Achados tomográficos incidentais de calcificações coronarianas: um estudo de prevalência na região sul do Brasil / Incidental tomographic findings of coronary artery calcifications: a prevalence study in southern Brazil

Fundamento: As calcificações de artérias coronárias (CAC) mostram-se como fator preditivo de doenças cardiovasculares (DCV). A tomografia computadorizada (TC) de tórax com protocolo de aquisição de baixa dose apresenta acurácia na identificação de CAC e propicia achados incidentais dessas calcificações, que são comumente negligenciados. Este estudo analisará a prevalência de achados incidentais de calcificação em artérias coronárias em indivíduos não cardiopatas submetidos à TC de tórax. Métodos: Estudo transversal consecutivo de caráter analítico e descritivo. Foram incluídos indivíduos de ambos os sexos que realizaram TC de tórax por encaminhamento, acima de 18 anos e não cardiopatas. A coleta de dados foi realizada por meio de prontuários e ficha de anamnese auto aplicada. As variáveis referentes às CAC e à extensão do comprometimento foram obtidas a partir da reavaliação das imagens de TC de tórax disponíveis no sistema da instituição. Os exames foram anonimizados e avaliados por dois médicos radiologistas experientes. Considerou-se como estatisticamente significativo p≤0,05. Resultados: Foram analisados 397 exames. Encontrou-se prevalência de calcificações em 176 (44%) dos casos. A existência dessas calcificações coronárias está relacionada à idade (p<0,001). As calcificações possuem relação com o sexo (p = 0,03) com maior razão de chance de desenvolvimento em homens (odds ratio [OR] = 1,55). O tabagismo (p<0,001), o sedentarismo (p<0,001), a hipertensão arterial sistêmica (p<0,001), o diabetes mellitus (p = 0,04) e as dislipidemias (p<0,001) mostraram associação positiva. Conclusão: A prevalência de achados incidentais de CAC foi de 44%; variam em maior número entre leve e grave; maior razão de chance no sexo masculino e aumento da prevalência com a idade. Portanto, a TC de tórax mostra-se um efetivo método para avaliar as CAC, e juntamente com a história clínica do paciente pode ser utilizada para medir os fatores de risco para doenças cardiovasculares e intervir no desfecho do quadro.(AU)

Introduction: Coronary artery calcifications (CAC) are shown to be a predictive factor of cardiovascular diseases. Computed tomography (CT) of the chest with a low-dose acquisition protocol is accurate in identifying CAC and provides incidental findings of these calcifications, which are commonly overlooked. This study will analyze the prevalence of incidental findings of calcification in coronary arteries in non-cardiac individuals undergoing chest CT. Methods: Consecutive cross-sectional study of an analytical and descriptive nature. Individuals of both genders who underwent chest CT by referral, over 18 years of age and without heart disease were included. Data collection was carried out using medical records and a self-applied anamnesis form. The variables referring to the CAC and the extension of the impairment were obtained from the reassessment of the chest CT images available in the institution's system. The exams were anonymized and evaluated by two experienced radiologists. P≤0.05 was considered statistically significant. Results: 397 exams were analyzed. A prevalence of calcifications was found in 176 (44%) of the cases. The existence of these coronary calcifications is related to age (p<0.001). Calcifications are related to gender (p = 0.03) with a higher odds ratio of development in men (odds ratio [OR] = 1.55). Smoking (p<0.001), sedentary lifestyle (p<0.001), systemic arterial hypertension (p<0.001), Diabetes Mellitus (p = 0.04), and dyslipidemia (p<0.001) showed a positive association. Conclusion: The prevalence of incidental CAC findings was 44%; vary in greater numbers between mild and severe; higher odds ratio in males and increased prevalence with age. Therefore, chest CT proves to be an effective method to assess CAC, and together with the patient's clinical history, it can be used to measure risk factors for CVD and intervene in the outcome of the condition.(AU)

Association of face mask use with self-reported cardiovascular symptoms during the COVID-19 pandemic

INTRODUCTION@#Countries are mandating the use of face masks to stem the spread of coronavirus disease 2019 (COVID-19). Face mask use has been associated with discomfort due to its effects on thermoregulation, breathing and oxygenation. We evaluated the prevalence and severity of self-reported cardiovascular symptoms before and during face mask use.@*METHODS@#This was a cross-sectional study of 1,001 participants residing in Singapore, who participated in a self-administered questionnaire between 25 April 2020 and 4 May 2020. Symptom severity before and during mask use, and health-seeking behaviour information were collected. The study outcome was self-reported worsening of cardiovascular symptoms and its association with the type of mask worn, duration of mask worn per day, and intensity of physical activities during mask use.@*RESULTS@#The most common symptom reported during mask use was dyspnoea. Independent predictors for self-reported cardiovascular symptoms during mask use were moderate-high physical activity during mask use (odds ratio [OR] 1.634, 95% confidence interval [CI] 1.176-2.270, P = 0.003), duration of mask use for ≥3 h (OR 1.672, 95% CI 1.189-2.352, P = 0.003) and type of mask used, after adjusting for age, sex, healthcare-based worker status and presence of comorbidities. N95 mask was associated with worse symptoms when compared to surgical mask. Participants with ≥3 worsening symptoms or worsening dyspnoea, palpitations, fatigue and dizziness were more likely to seek medical help.@*CONCLUSION@#Face mask use has been proven to be an effective way in curbing COVID-19 transmission. However, participants in this study had concerns regarding its use and these concerns should be urgently addressed to enable mask use policies to be enacted.

Congenital pulmonary alveolar proteinosis in a neonate / 中国当代儿科杂志

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

A case of acute severe cryptogenic organic pneumonia with secondary hemophilia / 中南大学学报(医学版)

Cryptogenic organic pneumonia (COP) refers to organic pneumonia that has not been identified a clear cause by current medical methods. A small proportion of COP can exhibit severe and progressive characteristics, while severe COP can cause systemic inflammatory storms and can be secondary to hemophilia. This article reported a case of acute severe COP secondary to hemophilia. A 67-year-old male patient was admitted to the hospital due to cough, shortness of breath, and fever. At first, he was misdiagnosed as severe pneumonia, but failed to receive anti infection treatments. Sputum pathogenetic examination and Macrogene testing of alveolar lavage fluid were performed, and no etiology was found to explain the patient's condition. The condition was gradually worsened and hemophilia occurred to explain, suggesting that acute severe COP was relevant. After receiving hormone treatment, the condition gradually relieved and the absorption of lung lesions improved. Hemophilia secondary to COP is rare, and the specific mechanism needs further study.

Comportamiento clínico y secuelas de la COVID-19 en niños / Clinical behavior and sequels of COVID-19 in children

La COVID 19 es una enfermedad que, habitualmente, no resulta grave en la edad pediátrica, excepto en niños con comorbilidades significativas subyacentes. Es muy importante reconocer los cuadros post COVID, como el síndrome inflamatorio multisistémico (SIM-C) y la COVID-19 prolongada o long COVID que pueden afectar de manera significativa a la población de niños y adolescentes. La pandemia COVID-19 también ha tenido un fuerte impacto en los aspectos sociales, emocionales y nutricionales. El aislamiento prolongado impactó en los controles de salud de niños y adolescentes con enfermedades crónicas y las coberturas de las vacunas de calendario disminuyeron significativamente. Es claro que la vacunación contra el SARSCov-2 en niños, niñas y adolescentes no sólo busca cuidar de su salud; también busca preservar la vida social y presencialidad escolar, reducir el riesgo de los cuadros post COVID-19 y mejorar la inmunidad de rebaño de la población general.

COVID-19 is a disease that is not usually serious in children, except in children with significant underlying comorbidities. Is very important to recognize post-COVID conditions such as multisystem inflammatory syndrome (SIM-C) and prolonged COVID ­ 19 or long COVID, which can significantly affect the population of children and adolescents. The COVID -19 pandemic has also had a strong impact on social, emotional, and nutritional aspects. Prolonged isolation had an impact on health checkups for children and adolescents with chronic diseases, and coverage of scheduled vaccinations decreased significantly. It is clear that vaccination against SARSCov-2 in children and adolescents not only seeks to take care of their health , it also seeks to preserve social life and school presence, reduce the risk of post-COVID-19 conditions and improve herd immunity in the general population.

Síndrome pos-COVID-19: solo sabemos que sabemos poco / Pos-COVID-19 syndrome: we only know how little we know

La COVID-19 puede producir síntomas persistentes luego de la infección inicial. En cuadros más graves, pueden corresponder a la evolución propia de una patología crítica o a secuelas inflamatorias/fibróticas pulmonares, entre otras. Esto puede confirmarse por estudios respiratorios e imagenológicos. En el caso de la COVID-19 no grave, el denominado síndrome pos-COVID-19, se trata de síntomas persistentes luego de al menos 28 días sin una secuela orgánica clara. Los síntomas más comunes en este caso son fatiga, cefalea y disnea, que pueden persistir meses luego de la infección inicial. Su curso puede ser oscilante e incluso aumentar progresivamente. El espectro de síntomas es muy amplio y requiere una adecuada evaluación del paciente. Se cree que tiene su origen en la desregulación inmunológica luego de la infección inicial. Su evaluación y seguimiento requieren un adecuado manejo sintomático y acompañamiento por el profesional a cargo. (AU)

Patients who underwent COVID-19 can develop persisting symptoms and sequelae. Severe cases may exhibit systemic complications of critical care and/or inflammatory/fibrotic lung injury. Imaging and respiratory function tests can assist in the evaluation of both. Nonsevere cases can also develop persisting symptoms for more than 28 days, which has been defined as the post COVID-19 syndrome. The most common symptoms in said syndrome are fatigue, headache and dyspnea, which can last for months. Its course can be oscillating or even increase progressively within the first months. The considerable range of symptoms requires proper patient assessment. Post-infectious immune disregulation is believed to be the source of this syndrome. Proper assessment and followup warrant measured symptom management and emphatic care by the attending physician. (AU)

Dyspnea and COVID-19: A Review of Confounding Diagnoses during the Postpartum Period / Dispneia e COVID-19: uma revisão de diagnósticos confundidores no período pós-parto

Abstract The puerperium is a complex period that begins with placental delivery and lasts for 6 weeks, during which readaptation of the female organism and redistribution of blood volume occur. This period is conducive to the occurrence of thromboembolic events. In the context of the SARS-CoV-2 pandemic, the virus responsible for COVID-19, the attention of the scientific community and health professionals has been focused on obtaining insights on different aspects of this disease, including etiology, transmission, diagnosis, and treatment. Regarding the pregnancy-postpartum cycle, it is opportune to review the clinical conditions that can occur during this period and to investigate dyspnea as a postpartum symptom in order to avoid its immediate association with COVID-19 without further investigation, which can lead to overlooking the diagnosis of other important and occasionally fatal conditions.

Resumo O puerpério é um período complexo que se inicia com a dequitação placentária e dura por 6 semanas, no qual a readaptação do organismo materno e a redistribuição do volume sanguíneo ocorrem, além de ser também um cenário propício para eventos pró-trombóticos. No contexto da pandemia de SARS-CoV-2, vírus responsável pela COVID-19, a atenção da comunidade científica e dos profissionais da saúde está voltada a elucidar os aspectos da doença, como a etiologia, a transmissão, o diagnóstico e o tratamento. Considerando o ciclo gravídico-puerperal, é oportuna a revisão de condições clínicas que ocorrem durante este período e que apresentam a dispneia como sintoma, a fimde evitar que ela seja automaticamente associada à COVID-19 sem investigações aprofundadas, o que pode levar à negligência do diagnóstico de outras condições importantes e que podem ser, por vezes, fatais.

Pulmonology approach in the investigation of chronic unexplained dyspnea / Abordagem pneumológica na investigação de dispneia crônica inexplicada

ABSTRACT Chronic unexplained dyspnea and exercise intolerance represent common, distressing symptoms in outpatients. Clinical history taking and physical examination are the mainstays for diagnostic evaluation. However, the cause of dyspnea may remain elusive even after comprehensive diagnostic evaluation-basic laboratory analyses; chest imaging; pulmonary function testing; and cardiac testing. At that point (and frequently before), patients are usually referred to a pulmonologist, who is expected to be the main physician to solve this conundrum. In this context, cardiopulmonary exercise testing (CPET), to assess physiological and sensory responses from rest to peak exercise, provides a unique opportunity to unmask the mechanisms of the underlying dyspnea and their interactions with a broad spectrum of disorders. However, CPET is underused in clinical practice, possibly due to operational issues (equipment costs, limited availability, and poor remuneration) and limited medical education regarding the method. To counter the latter shortcoming, we aspire to provide a pragmatic strategy for interpreting CPET results. Clustering findings of exercise response allows the characterization of patterns that permit the clinician to narrow the list of possible diagnoses rather than pinpointing a specific etiology. We present a proposal for a diagnostic workup and some illustrative cases assessed by CPET. Given that airway hyperresponsiveness and pulmonary vascular disorders, which are within the purview of pulmonology, are common causes of chronic unexplained dyspnea, we also aim to describe the role of bronchial challenge tests and the diagnostic reasoning for investigating the pulmonary circulation in this context.

RESUMO A dispneia crônica inexplicada e a intolerância ao exercício representam sintomas comuns e angustiantes em pacientes ambulatoriais. O histórico clínico e o exame físico são as bases da avaliação diagnóstica. No entanto, a causa da dispneia pode permanecer inexplicada mesmo após uma avaliação diagnóstica abrangente - análises laboratoriais básicas, exames de imagem do tórax, testes de função pulmonar e testes cardíacos. Nesse momento (e frequentemente antes), os pacientes geralmente são encaminhados a um pneumologista, o qual se espera que seja o principal médico para a resolução desse enigma. Nesse contexto, o teste de exercício cardiopulmonar (TECP), para avaliação de respostas fisiológicas e sensoriais do repouso ao pico do exercício, proporciona uma oportunidade única de desvendar os mecanismos subjacentes à dispneia e as interações desses mecanismos com um amplo espectro de distúrbios. No entanto, o TECP é subutilizado na prática clínica, possivelmente por questões operacionais (custos dos equipamentos, disponibilidade limitada e baixa remuneração) e limitação da formação médica em relação ao método. Para enfrentar esta última deficiência, almejamos fornecer uma estratégia pragmática para a interpretação dos resultados do TECP. O agrupamento dos achados da resposta ao exercício permite a caracterização de padrões que possibilitam ao clínico restringir a lista de possíveis diagnósticos, em vez de apontar uma etiologia específica. Apresentamos uma proposta de avaliação diagnóstica e alguns casos ilustrativos avaliados por TECP. Como a hiper-responsividade das vias aéreas e os distúrbios vasculares pulmonares, que são da competência da pneumologia, são causas comuns de dispneia crônica inexplicada, também objetivamos descrever o papel dos testes de broncoprovocação e o raciocínio diagnóstico para a investigação da circulação pulmonar nesse contexto.

Relação do tempo de trânsito faríngeo e presença de resíduo com dispneia e função pulmonar na doença pulmonar obstrutiva crônica / Relationship of pharyngeal transition time and presence of residue with dyspnea and lung function in chronic obstructive pulmonary disease

RESUMO Objetivo Relacionar o tempo de trânsito faríngeo e a presença de resíduos com a dispneia e a função pulmonar em indivíduos com Doença Pulmonar Obstrutiva Crônica DPOC. Método Estudo realizado com 19 adultos (11 homens e 8 mulheres) com diagnóstico clínico e espirométrico de DPOC e idade média de 63,8 (±9,3) anos. A coleta de dados foi realizada utilizando o questionário COPD Assessment Test (CAT, Teste de Avaliação da DPOC) a escala de dispneia do Medical Research Council modificada (mMRC) e um manovacuômetro digital, para caracterizar o impacto da doença no indivíduo, a dispneia e a função pulmonar. Os dados referentes ao tempo de trânsito faríngeo e resíduo faríngeo foram coletados por meio de análise das imagens videofluoroscópicas realizada por três juízes cegados. Resultados Não foram encontradas relações significativas entre tempo de trânsito faríngeo (TTF) com função pulmonar (r = -0,71), e entre presença de resíduo faríngeo com a dispneia (r= -0,06). O TTF, quando comparado com a normalidade, apresentou-se aumentado. Conclusão Os indivíduos com DPOC, independente da gravidade da doença, não manifestaram associação entre alterações no TTF e resíduo faríngeo e dispneia e função pulmonar.

ABSTRACT Purpose To relate pharyngeal transit time and the presence of residues with dyspnea and lung function in individuals with Chronic Obstructive Pulmonary Disease COPD. Methods Study conducted with 19 adults (11 men, 8 women) with a clinical and spirometric diagnosis of COPD and a mean age of 63.8 years (SD = 9.3). Data collection was performed using the COPD Assessment Test (CAT) questionnaire, the modified Medical Research Council scale (mMRC) and a digital manovacuometer, to characterize the impact of the disease on the individual, dyspnea and lung function. The data related to pharyngeal transit time and pharyngeal residue were collected through the analysis of videofluoroscopic images performed by three blinded judges. Results No significant relationship was found between pharyngeal transit time (PTT) with lung function (r = -0.71), pharyngeal residue and dyspnea (r = -0.06). PTT, when compared to normality, was increased. Conclusion Individuals with COPD, regardless of the severity of the disease, showed no association between PTT and pharyngeal residue and dyspnea and lung function.

Respiratory symptoms (COPD Assessment Test and modified Medical Research Council dyspnea scores) and GOLD-ABCD COPD classification: the LASSYC study / Sintomas respiratórios (Teste de Avaliação da DPOC e pontuação modificada de dispneia do Conselho de Pesquisa Médica) e classificação GOLD-ABCD COPD: o estudo LASSYC

ABSTRACT Objective To assess the frequency and severity of 24-hour respiratory symptoms according to COPD GOLD-ABCD classification (2017-version), the distribution of the patients with COPD into GOLD categories using mMRC (≥2) or CAT (≥10) scores, and agreement between these cut-off points. Methods In this cross-sectional study (LASSYC study), 24-hour day respiratory symptoms were assessed by the Evaluating Respiratory Symptoms in COPD (E-RS) questionnaire, Nighttime Symptoms of COPD Instrument (NiSCI), Early Morning Symptoms of COPD Instrument (EMSCI), CAT and mMRC scores. Results Among the 734 patients with COPD, 61% were male, age 69.6±8.7 years, FEV1% post-BD 49.1±17.5%, mMRC 1.8±1.0 and CAT 15.3±.8.1. By mMRC 33.7% were group-A, 29.2% group-B, 10.2% group-C and 26.9% group-D. By CAT 22.3% were group-A, 41% group-B, 4.8% group-C and 31.9% group-D. Using the mMRC the severity of E-RS, NiSCI and EMSCI scores increased from group A to D. Using the CAT, the groups B and D had the higher scores. Agreement between mMRC and CAT was 89.5% (Kappa statistics=75.7%). For mMRC score of 2, CAT score of ≥11 showed the maximum Youden's index (1.34). For mMRC score of 1, CAT score of ≥9 and ≥10 showed the maximum Youden's index (1.48). Conclusion GOLD COPD classification by CAT seems to better discriminate 24-hour symptoms. Results do not support the equivalent use of CAT≥10 and mMRC≥2 for assessing symptoms.

Por mMRC 33,7% eram do grupo A, 29,2% do grupo B, 10,2% do grupo C e 26,9% do grupo D. Por CAT, 22,3% eram do grupo A, 41% do grupo B, 4,8% do grupo C e 31,9% do grupo D. Usando o mMRC, a gravidade dos escores E-RS, NiSCI e EMSCI aumentou do grupo A para D. Usando o CAT, os grupos B e D tiveram os escores mais altos. A concordância entre mMRC e CAT foi de 89,5% (estatística Kappa = 75,7%). Para a pontuação mMRC de 2, a pontuação CAT ≥11 mostrou o índice de Youden máximo (1,34). Para a pontuação mMRC de 1, a pontuação CAT ≥9 e ≥10 mostrou o índice de Youden máximo (1,48). Conclusão A classificação GOLD COPD por CAT parece discriminar melhor os sintomas de 24 horas. Os resultados não suportam o uso equivalente de CAT≥10 e mMRC≥2 para avaliação dos sintomas.

Paraganglioma Cardíaco: reporte de un caso / Cardiac Paraganglioma: case report

Abstract: A 49-year-old woman presented with dyspnea and palpitations, leading to Functional Class III.An echocardiogram showed a heterogeneous mass adhered to the right heart cavities. This was confirmed by NMR. A large right coronary artery was occluded in relation to the tumor, which was hyper vascularized. Resection of the tumor was performed; the right ventricular wall was sutured, and an atrial defect was closed using pericardial tissue. Post operative course was uneventful and she was asymptomatic 4 years after surgery.

Panic disorder respiratory subtype: psychopathology and challenge tests - an update

Panic disorder (PD) pathophysiology is very heterogeneous, and the discrimination of distinct subtypes could be very useful. A subtype based on respiratory symptoms is known to constitute a specific subgroup. However, evidence to support the respiratory subtype (RS) as a distinct subgroup of PD with a well-defined phenotype remains controversial. Studies have focused on characterization of the RS based on symptoms and response to CO2. In this line, we described clinical and biological aspects focused on symptomatology and CO2 challenge tests in PD RS. The main symptoms that characterize RS are dyspnea (shortness of breath) and a choking sensation. Moreover, patients with the RS tended to be more responsive to CO2 challenge tests, which triggered more panic attacks in this subgroup. Future studies should focus on discriminating respiratory-related clusters and exploring psychophysiological and neuroimaging outcomes in order to provide robust evidence to confirm RS as a distinct subtype of PD.
