An unusual site of a pericardial cyst in a child: A case report.

Pericardial cysts are rare congenital anomalies, often clinically silent and incidentally found on imaging. However, patients with pericardial cysts may present with chest pain, tachypnea, and, rarely, symptoms secondary to cardiac tamponade. Echocardiography (transthoracic or transesophageal) and chest computed tomography (CT) scan with contrast are diagnostic modalities of choice in patients with pericardial cysts. Conservative management is justified in asymptomatic patients, while a surgical approach is recommended in symptomatic patients. Here, we describe the case of a 12-year-old boy who underwent imaging during the coronavirus disease 2019 (COVID-19) pandemic and was incidentally found to have a pericardial cyst.

Factors associated with mortality in hospitalized cardiovascular disease patients infected with COVID-19.

INTRODUCTION: To reduce mortality in hospitalized patients with COVID-19 and cardiovascular disease (CVD), it is necessary to understand the relationship between patient's symptoms, risk factors, and comorbidities with their mortality rate. To the best of our knowledge, this paper is the first which take into account the determinants like risk factors, symptoms, and comorbidities leading to mortality in CVD patients who are hospitalized with COVID-19. METHODS: This study was conducted on 660 hospitalized patients with CVD and COVID-19 recruited between January 2020 and January 2021 in Iran. All patients were diagnosed with the previous history of CVD like angina, myocardial infarction, heart failure, cardiomyopathy, abnormal heart rhythms, and congenital heart disease before they were hospitalized for COVID-19. We collected data on patient's signs and symptoms, clinical and paraclinical examinations, and any underlying comorbidities. t test was used to determine the significant difference between the two deceased and alive groups. In addition, the relation between pairs of symptoms and pairs of comorbidities has been determined via correlation computation. RESULTS: Our findings suggest that signs and symptoms such as fever, cough, myalgia, chest pain, chills, abdominal pain, nausea, vomiting, diarrhea, and anorexia had no impact on patients' mortality. There was a significant correlation between COVID-19 cardiovascular patients' mortality rate and symptoms such as headache, loss of consciousness (LOC), oxygen saturation less than 93%, and need for mechanical ventilation. CONCLUSIONS: Our results might help physicians identify early symptoms, comorbidities, and risk factors related to mortality in CVD patients hospitalized for COVID-19.

The Correlation of Health-Related Quality of Life with Cystic Fibrosis Severity Markers in Chest CT Scan and 6-Minute Walk Test: A Cross-Sectional Study.

OBJECTIVE: To investigate the correlation between severity of lung disease determined by chest computed tomography (CT) and 6-min walk test (6MWT) with health-related quality of life (HRQoL) score in cystic fibrosis (CF) patients. METHODS: This cross-sectional study evaluated 76 CF patients referred to CF Clinic, aged 7-14 y. Subjects were asked to complete Pediatric quality of life (PedsQL4.0) forms, during their outpatient visits to determine their HRQoL score. Patients' lung disease severity was quantified by Bhalla score determined by the child's chest CT and their 6MWT. These three variables were then analyzed to determine whether there is correlation between HRQoL with severity of lung disease. RESULTS: The mean distance of patients 6MWT score was 447.4 ± 81.4 m. There was a positive correlation between distance and HRQoL score in total, social, school and emotional function (p < 0.05). However, in physical function the correlation lacked significance (p = 0.07). Patients with a Bhalla score of less than 15 were older than patients with a Bhalla score of more than 15 (p < 0.001). Physical, emotional, social, school, and total function scores were significantly lower in patients with Bhalla score less than 15, compared to those with Bhalla score greater than 15 (p < 0.05). CONCLUSIONS: The correlation among Bhalla score on CT scan, 6-min walk test, and HRQoL indicates that pulmonary disease has a clear impact on the quality of life of CF patients. HRQoL can be used in the care program of children with CF.

The correlation between 6-min walk test and respiratory parameters in children with cystic fibrosis.

BACKGROUND: The 6-min walk test (6MWT) is a sub-maximal exercise test and has been widely used for evaluating of exercise capacity of patients with cystic fibrosis (CF) in recent years. Few studies have examined the relationship between 6MWT and parameters used to assess the severity of the disease in children with CF. In this study, we have examined this relationship to find out if 6MWT can be a marker of the severity of cystic fibrosis. METHODS: A cross-sectional study was done to analyze the correlations among spirometry parameters, body mass index (BMI), chest tomography (CT), and 6MWT. CF patients, aged 7-14 years, were involved. RESULTS: Seventy-six patients, 32F/44M, mean age 10.49 ± 3.18 years, were studied. The mean distance in 6MWT was 447 ± 84.1. The following correlations versus distance were found: FEV1 (r = 0.255, p = 0.026), FVC(r = 0.285, p = 0.013), FEF25-75% (r = 0.546, p < 0.001), BMI (r = 0.163, p = 0.160), and CT (r = 0.075, p = 0.520).The following correlations versus O2 saturation (SpO2) decline were found: FEV1 (r = -0.393, p < 0.001), FVC (r = -0.431, p < 0.001), FEF25-75% (r = -0.296, p = 0.010), BMI (r = 0.042, p = 0.721), and CT (r = -0.196, p = 0.090). There was a significant correlation between 6MWT (distance and SpO2 decline) and pulmonary function test. There was no significant correlation between BMI, chest CT, and 6MWT. CONCLUSIONS: 6MWT can be applied beside spirometry and chest CT for CF patients follow up.

Risk factors prediction, clinical outcomes, and mortality in COVID-19 patients.

Preventing communicable diseases requires understanding the spread, epidemiology, clinical features, progression, and prognosis of the disease. Early identification of risk factors and clinical outcomes might help in identifying critically ill patients, providing appropriate treatment, and preventing mortality. We conducted a prospective study in patients with flu-like symptoms referred to the imaging department of a tertiary hospital in Iran between March 3, 2020, and April 8, 2020. Patients with COVID-19 were followed up after two months to check their health condition. The categorical data between groups were analyzed by Fisher's exact test and continuous data by Wilcoxon rank-sum test. Three hundred and nineteen patients (mean age 45.48 ± 18.50 years, 177 women) were enrolled. Fever, dyspnea, weakness, shivering, C-reactive protein, fatigue, dry cough, anorexia, anosmia, ageusia, dizziness, sweating, and age were the most important symptoms of COVID-19 infection. Traveling in the past 3 months, asthma, taking corticosteroids, liver disease, rheumatological disease, cough with sputum, eczema, conjunctivitis, tobacco use, and chest pain did not show any relationship with COVID-19. To the best of our knowledge, a number of factors associated with mortality due to COVID-19 have been investigated for the first time in this study. Our results might be helpful in early prediction and risk reduction of mortality in patients infected with COVID-19.
