The comparison of different dyspnoea scales in patients with COPD
Objectives (i) to compare the relationship between different dyspnoea scales and physical and clinical parameters of patients with chronic obstructive pulmonary disease (COPD); and (ii) to determine the most suitable scale among these scales for this patient group. Methods Forty patients with COPD [mean 1st second forced expiratory volume (FEV1), 49.16 +/- 2.33% predicted], aged 53-85 participated in this study. The severity of dyspnoea was assessed with different five scales [Modified Borg Scale (MBS), Visual Analogue Scale (VAS), Medical Research Council Dyspnoea Scale (MRCS), Baseline Dyspnoea Index (BDI) and Oxygen Cost Diagram (OCD)]. As clinical parameters, respiratory function was measured by means of pulmonary function test and arterial blood gas analysis. As physical parameters, age and body mass index was recorded. Results Patient's dyspnoea severities were 1.59 +/- 2.75, 2.03 +/- 2.82, 2.14 +/- 1.44, 6.81 +/- 4.07, 4.56 +/- 2.47 for MBS, VAS, MRCS, BDI, OCD, respectively (P = 0.08). It was proven that only %FEV1 had a correlation with MRCS (r = -0.67, P = 0.01) and BDI (r = 0.58, P = 0.02). In addition to these determinations MRCS, MBS and VAS had a strong correlation defining their relationships with each other (P < 0.05). Conclusions MRCS and BDI could assess dyspnoea during daily activities, so these scales showed strength correlation with physical and clinical values. Briefly MRCS is the most suitable dyspnoea scale for the patients with COPD, moreover, BDI, as the second suitable scale, is correlated only with MRCS. Based on these findings, we recommended that MRCS and BDI are appropriate scales for evaluation of dyspnoea in the patients with COPD
Corticosteroid Responsive Sarcoidosis with Multisystemic Involvement Years after Initial Diagnosis: A Lymphoma Mimicker on 18-FDG PET/CT
WOS: 000219260600002PubMed ID: 26312138Sarcoidosis is a chronic multisystemic inflammatory disease characterized by noncaseating epithelioid cell granulomas. 18-Fluorodeoxyglucose positron-emission tomography/computer tomography (FDG-PET/CT) is increasingly used in routine clinical practice to assess active sarcoidosis because it can detect active inflammatory granulomatous disease. However, active sarcoidosis lesions are observed to be hypermetabolic on FDG-PET/CT much like malignancies, which may lead to misinterpretation on imaging. In this case report, we present a rare case of sarcoidosis with multisystem involvement including lung, lymph nodes, bone, pleura, and soft tissue that mimicked lymphoma on FDG-PET/CT and responded to corticosteroid treatment
Gait speed as a functional capacity indicator in patients with chronic obstructive pulmonary disease
AIM: Walking distance is generally accepted as a functional capacity determinant in chronic obstructive pulmonary disease (COPD). However, the use of gait speed in COPD patients has not been directly investigated. Thus, the aim of our study was to assess the use of gait speed as a functional capacity indicator in COPD patients
PCR and serology were effective for identifying Chlamydophila pneumoniae in a lower respiratory infection outbreak among military recruits
During endemic infections, the sensitivity of diagnostic tests and rapid diagnosis of the respiratory tract pathogens is particularly important. Utilization of just one diagnostic technique, such as serological tests or polymerase chain reaction (PCR)-based detection methods, during outbreaks of lower respiratory tract infections (LRI) can result in some of the patients being missed. In this study we aimed to investigate the etiology of LRI in military recruits in Izmir, Turkey, among whom several pneumonia cases have been reported and 47 patients have been hospitalized. Nasopharyngeal swabs were used for PCR analysis of Chlamydophilapneumoniae, Mycoplasma pneumoniae and Legionella spp. Serum samples were collected in the acute and convalescent phase of infection for C. pneumoniae and M. pneumoniae. Thirty-nine patients were diagnosed with C. pneumoniae infection by PCR and/or serology. Diagnoses were established by PCR in the acul:e phase of infection in 40.4% of the group. Based on the results of these studies, PCR is a useful method for early detection and identification of C. pneumoniae-related LRI outbreaks. However, this technique is not sufficient to detect all positive cases per se. After effective therapy and introduction of appropriate infection control measures, the outbreak ceased without mortality. This is the first closed-community C. pneumoniae outbreak report from Turkey
Microbiologic spectrum and prognostic factors of hospital-acquired pneumonia cases
Nosocomial infections are an important cause of preventable morbidity and mortality; they also result in significant socioeconomic cost. Nosocomial pneumonia (NCP) is defined as pneumonia, which occurs 48 hours after hospitalization or after discharge from the hospital. It is the second or third most frequent infection among all hospital acquired infections, and the mortality of NCP is higher than the other hospital acquired infections. Patients, diagnosed as NCP were retrospectively analyzed in order to detect microbiological agent and prognostic factors. We evaluated 173 patients, 67.0% of them were male and 33.0% female. Comorbid diseases were present in 94.2% and a medical procedure had been applied in 75.1% of cases. A single agent was isolated in 79.2% of the cases while a mixt infection was present in 13.3%. In 7.5% of the cases, cultures were negative. Endotracheal aspirates were the most common materials (38.9%) used for dedected microorganism and sputum cultures were used in 16.8% of the cases. Most commonly encountered microorganism were Pseudomonas aeruginosa, Acinetobacter spp. and Staphylococcus aureus respectively. NCP developed on approximately 18th day of hospitalization. Overall mortality rate was 45.2%. The effects of diabetes mellitus and chronic pulmonary diseases on mortality rate were analized by logistic regression analysis and it's evaluated that the mortality rates increase 3.7 times with diabetes mellitus and 2.4 times with chronic pulmonary diseases. There was no effect of mechanical ventilation history on mortality
Pathological and immunohistochemical findings of lungs, heart, liver, and kidneys, and unexpected findings of fungi and parasites in lungs of deceased COVID-19 patients: A case series
Objective: To define histopathologic and immunohistochemical features of the lungs, heart, liver, and kidneys in patients who died from coronavirus disease 2019 (COVID-19), and to determine the presence of SARS-CoV-2 in all tissues, as well as the presence of fungi and parasites in lung tissues.Methods: This retrospective case study was conducted in the intensive care units of Dokuz Eyl & uuml;l University Hospital, and patients (>= 18 years) who died due to COVID-19 between October 2020 and April 2021 were included. The biopsy samples of the patient's lung, heart, liver, and kidney tissues were studied.Results: In the study, we enrolled 12 patients (mean age: 70 years; 50% male). Alveolar epithelial cell damage and diffuse alveolar damage were predominant in lung tissues. Lobular lymphocyte infiltration, centrilobular sinusoidal dilatation, and microvesicular steatosis in the liver, together with pigmented cast, non-isometric vacuolar degeneration, and capillary plugging in the kidneys, were commonly found among the patients. SARS-CoV-2 nucleocapsid protein antibodies were detected in three lung and two kidney tissues, and so did angiotensin-converting enzyme 2 receptor positivity in one lung and more than half of the kidney tissues. The RT-PCR tests were positive in three lungs and one kidney tissue. After DNA isolation from lung tissues, Pneumocystis jirovecii was detected in nine patients, Aspergillus fumigatus in two, Microsporidia in three, and Cryptosporidium in two.Conclusions: SARS-CoV-2 is a multisystemic disease. Fungi and parasites should be investigated in critically ill COVID-19 patients prescribed corticosteroids
