The application of pulmonary rehabilitation (PR) may have some benefits in patients with ILDs. Aim The aim of this study was to evaluate the effect of PR program on ILD patients’ QOL, exercise capacity, dyspnea, and spirometry. Settings and design This was a single-center experimental randomized controlled study. Patients and material This study initially enrolled 62 patients previously diagnosed as having ILD at the Chest Department according to American Thoracic Society (ATS)/European Respiratory Society (ERS) diagnostic criteria; however, 12 patients were excluded, and only 50 patients were included and completed the study, and they were classified randomly into the control group (n=25, received conventional treatment only) and the PR group (n=25, received conventional treatment and PR). Pre-PR and post-PR program assessment of QOL by the 36-item short-form health survey (SF36) questionnaire, exercise capacity by the 6-min walk test, dyspnea by the modified Medical Research Council and spirometry were carried out. Statistical analysis used All data were collected, tabulated and statistically analyzed using SPSS 16.0 for Windows. Results This study showed a statistically significant difference for the PR group over the control group at the end of the PR program, wherein all components of the SF36Q score had a P value less than 0.05, dyspnea score by modified Medical Research Council (P=0.02) and exercise tolerance by 6 min walking distance test (P=0.005). Moreover, the maximum voluntary ventilation (MVV%) showed a statistically significant improvement (P=0.003) in contrast to the other measured spirometric parameters measured in this study (forced vital capacity, forced expiratory volume in 1 s, forced expiratory volume in 1 s/forced vital capacity %, forced expiratory flow25–75) wherein P value was more than 0.05. A negative correlation was found between the baseline physical functioning item of SF36Q and the change (Δ) in 6 min walk distance test. Conclusion PR could be considered as an adjuvant method in the treatment of patients with stable ILDs and could provide improvement in their dyspnea perception, exercise tolerance, and health-related QOL.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47793750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the aim of this study is to identify the prevalence of erectile dysfunction (ED) and its predictors in male patients with IIPs. Patients and methods A total 65 male patients (45 IIPs and 20 controls) were assessed; clinical data, testosterone levels, pulmonary function tests, arterial blood gases, and self-reported questionnaires on erectile function. Results The prevalence of ED was 66.7 and 11.1% of them presented with severe ED. The mean age of the patients was 33.4±5.9 years. Of the patients, 60% were smokers and 17.8% were nonsmokers. Regarding comorbid manifestations, 26.7% was hypertensive, 51.1% had diabetes mellitus, 42.2% with dyslipidemia, and 17.8% had ischemic heart disease. The mean duration since the diagnosis of IIPs was 7.46±2.77 years, whereas the mean time since evolution of ED was 2.17±1.3 years. A significant decrease in mean arterial oxygen tension (PaO2) and oxygen saturation (SaO2) were observed in the IIPs group. Also, the mean diffusion lung capacity for carbon monoxide (DLCO%) and testosterone level were decreased. A significant decrease in testosterone level among patients with severe diffusion defect was observed (P=0.000). The most predictors for ED were PaO2 (≤60 mmHg), SaO2 (≤88%), and DLCO≤60%. Conclusion ED is a common problem in patients with IIPs. Thus, physicians should keep in mind that IIPs patients need a comprehensive sexual evaluation. This is the first study to report that low PaO2, SaO2, and DLCO≤60% were the predictor risk factors.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42815519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability of computed tomography (CT) to differentiate transudate effusion from exudate effusion is still under research. Objective The aim of this study was to assess the accuracy of the CT in diagnosing the nature of the pleural effusion. Patients and methods In this prospective cross-sectional analytic study, laboratory biochemistry markers were used to classify pleural effusion into exudate or transudate based on Light’s criteria. Chest CT without contrast had been done for all patients, and CTs were diagnosed by the radiologist. Measurement of the pleural fluid density was done and shown using the CT attenuation values [Hounsfield unit (HU)]. Results Of 79 patients with pleural effusion, 60 patients had exudate effusion and 19 patients had transudate. The mean attenuation values were significantly higher in exudate effusion (20.11±7.11 HU) versus transudate effusion (13.8±4.11 HU), with P value of 0.03. Receiver operating characteristic curve analysis showed that the cutoff for exudate effusion was optimal at greater than or equal to 15.33 versus less than 15.33 HU for transudate (area under the curve=0.57; 95% confidence interval: 0.45–0.68). This point had 85.71% sensitivity and 46.55% specificity. Conclusion We reasoned the CT attenuation values of the pleural fluid may replace the laboratory tests in characterizing the pleural effusion, either exudate or transudate. However, there was an overlapping HU values in most effusions. So correlation of the CT results with the clinical findings is essential, and further CT studies are highly recommended to confirm and validate these findings.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44087522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and methods A prospective study including 70 (64 males and six females) patients with stable COPD was conducted. Clinical assessment, pulmonary function, and other laboratory studies were performed. Results MetS was present in 31 patients with COPD (44.3%). BMI and high-sensitivity C-reactive protein were significantly higher in patients with COPD with MetS than those without MetS (P=0.02 and 0.01, respectively). Age of the patients, duration of COPD, grade of dyspnea, and pulmonary function tests had no significant difference between those with MetS versus those without it. There was a significant negative correlation between plasma triglyceride level, as the only one of the variables of MetS, and some of parameters of pulmonary function test.

Aim of study The aim of this study was to estimate VAP incidence in Tanta University Hospitals ICUs. Settings and design This was a crossover observational study. Patients and methods This was a one-year study (April 2015 to March 2016), including patients on invasive ventilation who developed VAP, with evaluation of admission and ventilation causes, isolation of causative organisms, and study of used antibiotics and ventilation modes. Statistical analysis Data were statistically analyzed using the SPSS software for Windows (IBM SPSS Statistics 21.0). Results It is a statistics based study aimed to trace infection incidence in national hospital ICUs. Among 222 admitted patients, only 38.4% fulfilled the criteria of VAP. Admission was because of cardiovascular impairment, cardiac arrest, respiratory failure, or head trauma. The ventilation mode at VAP time was assisted control (75%) and synchronized intermittent mandatory ventilation (25%). The minimum intubation period was 7 days, whereas the maximum period was 37 days. Isolated organisms were Pseudomonas (37.5%), Klebsiella (25%), Staphylococcus (20.8%), and methicillin-resistant Staphylococcus aureus (4.2%). The antibiotics used were amikacin, imipenem, vancomycin, levofloxacin, ceftazidime, and teicoplanin (29, 25, 21, 12.5, 8.3, and 4.2%, respectively). The minimum period of antibiotic used was 5 days, whereas the maximum period was 35 days. The highest incidence of VAP occurred in February, whereas the lowest incidence occurred in July. Conclusion The incidence of VAP is still high and varies according to the intubation cause and period, and the underlying morbidity. More efforts must be made to prevent, diagnose, and manage infection early and properly to reduce patient suffering and to reduce the burden on the serving hospitals.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48482161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its diagnosis is based on definite high-resolution computed tomography pattern and is associated with the histopathological and/or radiological pattern of usual interstitial pneumonia with exclusion of other causes of interstitial pneumonia. The surfactant protein-D (SP-D) level in the serum is measured in several lung diseases, including IPF. Aim of study The aim of the current study is to assess the serum level of SP-D as a potential biomarker to distinguish between IPF and other idiopathic interstitial pneumonia patients. Patients and methods This study was conducted in the Chest Department, Kasr Al Ainy Hospitals, Cairo University. The study population included 20 healthy controls, 20 IPF patients, and 18 other idiopathic interstitial pneumonia patients. All were subjected to full history taking, clinical examination, high-resolution computed tomography chest, spirometry, arterial blood gases, blood samples for measuring SP-D by enzyme-linked immunosorbent assay. Results There was no statistical significance between the serum level of SP-D in IPF and non-IPF patients, however, there was a significant increase in the serum level of SP-D in IPF patients diagnosed at a late stage compared with those diagnosed at an early stage and those on anti-fibrotic therapy. Also, there was a statistical significance between the degree of clubbing and gastroesophageal reflux disease and the serum level of SP-D with a P value of 0.005 and 0.029, respectively. Serum SP-D level had a negative correlation with more severe form of the disease regarding the duration of illness, forced vital capacity percent, and it had a significant negative correlation with oxygen saturation and 6 min walk distance with a P value of 0.023 and 0.005, respectively.

Aim The aim of this study was to evaluate the role of measuring the gradient between EtCO2 and PaCO2 in adults with acute respiratory distress (ARDS). Settings and design This was a prospective consecutive enrollment study. Patients and methods Overall, 51 cases were recruited after the diagnosis of ARDS was made according to the Berlin definition. Patients were mechanically ventilated as per the lung-protective protocol. Daily arterial blood gases were collected and for every sample, the EtCO2 value was collected electronically by capnography using an endotracheal tube for the first 5 days. Results Cases were classified into survivors and nonsurvivors: 26 cases were because of extrapulmonary causes and 25 cases were because of pulmonary causes. The mean value of the APACHE II score for all cases on admission was 21.6. The mean length of ICU stay was 12.7 days. For all study cases, PaO2/FiO2 was the lowest at day 1 and the highest at day 5. We found a significant negative correlation between PaO2/FiO2 and the gradient at days 2, 4, and day 5, and a significant positive correlation between the gradient on admission and the APACHE II score (r=0.4, P≤0.05). Nonsurvivors had a significantly higher gradient and lower EtCO2 and PaO2/FiO2 levels at all time intervals, whereas PaCO2 alone was found to be nonsignificant.

Patients and methods Twenty patients with stable COPD, 20 patients with AECOPD, and 12 controls were included in this study. All participants were males. BMI, routine laboratory investigations, sputum and serum leptin levels, serum tumor necrosis factor (TNF-α), and C-reactive protein (CRP) levels were measured twice in patients with AECOPD (initially and after 7 days of management) and only once in stable patients and controls. Results In patients with patients with AECOPD, there were significant differences between sputum leptin and serum TNF-α, CRP, and leptin levels before and after treatment. Sputum leptin and serum CRP levels were significantly higher in the AECOPD group than other groups. Additionally, serum TNF-α levels were significantly higher in patients with AECOPD than the controls. Insignificant correlation was found between AECOPD and stable groups regarding serum leptin and TNF-α levels.
