The prevalence of ACO differs according to the diagnostic criteria and study design. In patients with COPD, the prevalence of ACO varies from 5 to 55%. This study aims to examine the effect of using different diagnostic criteria on the resulting frequency of ACO in patients with COPD. Settings and design This cross-sectional observational study enrolled 60 patients with COPD randomly selected from outpatient clinics of Chest Department of Minia Cardio-Thoracic University Hospital during the period from September 2015 to September 2016. Patients and methods History, clinical examination, spirometry, and sputum cytology were done. The frequency of ACO among the 60 patients with stable COPD was separately studied based on five different diagnostic criteria (Hardin’s, Menezes, combined Hardin and Menezes, Spanish consensus, and Global Initiative for Asthma-Global Initiative for Chronic Obstructive Lung Disease criteria). Statistical analysis Statistical analysis was performed using statistical package for social science software (χ2 test and independent sample t test). Results The frequency of ACO in COPD was 40, 23.3, 16.7, 13.3, and 10% on applying combined Hardin and Menezes, Hardin’s alone, Menezes alone, the Spanish consensus, and Global Initiative for Asthma-Global Initiative for Chronic Obstructive Lung Disease criteria, respectively.

Aims To evaluate the efficacy of EBUS-transbronchial needle aspiration (TBNA) in sampling mediastinal lesions after conventionally negative TBNA result and to compare EBUS-TBNA sampling in subcarinal and hilar sites versus paratracheal sites regarding diagnostic yield. Settings and design A prospective evaluation study was done. Patients and methods The study enrolled 52 patients with undiagnosed mediastinal lymphadenopathy or lesions. Subcarinal lesions were sampled by both conventional TBNA and EBUS-TBNA sampling (after negative conventional sampling results), and paratracheal lesions were sampled only with EBUS. Statistical analysis used Data were analyzed to test statistical significant difference between groups. Quantitative data were presented as mean±SD, and Student t test was used to compare between two groups. Results No complications were reported. Conventional subcarinal TBNA sampling was done in 37 cases, where sufficient sampling was seen in 67.6% of cases, was diagnostic in 16.2% and had sensitivity of 20%. EBUS-TBNA was done in 22 cases after negative conventional sampling result, and in additional 15 cases as an initial procedure during the study.

Sedation is necessary to facilitate mechanical ventilation. The effect of no-sedation strategy on different patient parameters on the ventilator has not yet been well studied. The aim of this study was to test the efficacy of no-sedation protocol in controlling COPD patient’s gasometric and clinical parameters during mechanical ventilation. Patients and methods Patients with COPD who required mechanical ventilation were randomized to either: sedated with daily interruption (control group) (n=50) or nonsedated group (n=47). The change in the partial pressure of arterial CO2 (PaCO2) was the primary outcome measure. Secondary outcome measures included: changes in pH, heart rate (HR), mean arterial blood pressure (MAP), respiratory rate, airway occlusion pressure (P0.1), and negative inspiratory force (NIF). Recordings for arterial blood gases, HR, MAP, and respiratory rate were performed as baseline at intubation, 1, 2, 12, 24, and 48 h after intubation. NIF and P0.1 were recorded 48 h after intubation. Results No significant difference was found in baseline recordings of PaCO2, pH, HR, MAP, and respiratory rate between the sedated and nonsedated groups. Further recordings of PaCO2 (P_1, P_2, P_3, and P_4<0.001, P_5=0.005), HR (P<0.001), and respiratory rate (P<0.001) were significantly higher in the nonsedated group. The rate of correction of pH from acidosis was faster among the sedated patients. MAP was significantly higher in nonsedated patients in recordings 2, 12, and 48 h after intubation (P_1=0.9, P_2<0.001, P_3<0.001, P_4=0.87, P_5<0.001). No significant difference was found in NIF or P0.1 between the two groups (P=0.8 and 0.1, respectively).

However, literature available on assessment and management of primary spontaneous pneumothorax (PSP) based on radiological quantitation is scarce. This study was undertaken to compare two different methods of quantitating pneumothorax size with that recommended in American Thoracic Society (ATS) guideline on chest radiogram with respect to possible change in management practices. Patients and methods A prospective cohort of adults presenting with spontaneous pneumothorax (SP) over 3 years to Emergency and Pulmonology Department, St John’s Medical College Hospital, Bangalore, was included. Demographic characteristics and clinical presentation were compiled. Management of SP was based on ATS guidelines. PSP size on chest radiogram was requantitated in the included patients using Light’s index and Collin’s method and was compared with that proposed by the ATS guideline. Results Seventy-six participants with SP were studied; their mean age was 43.7 years, with a preponderance of male patients (84.2%). Twenty-four (31.6%) patients had PSP and 52 (68.4%) patients had secondary spontaneous pneumothorax. In PSP, there was poor agreement between various methods of estimating size of pneumothorax on chest radiogram (Kappa statistic=0.23; ICC of 0.263). Three (12.5%) of the 24 incidences of PSP, which were treated conservatively as per ATS guidelines, would have required invasive intervention if Light’s index or the Collin’s formula were taken into consideration. Conclusion There was poor agreement of radiological pneumothorax size estimation by Collin’s, Light’s, and that proposed in the ATS guidelines.

The biological role of telomeres is to prevent shortening of DNA to preserve integrity of the genome. Length of telomeres is determined by age, sex, and environmental exposures. Telomeres are vulnerable to injury by oxidative stress. Telomere length is sustained by telomerase, a ribonucleoprotein telomerase reverse transcriptase (TERT). Telomerase may help cell growth and secure against cell death. ‘Telomeropathy’ is associated with genetic mutations. The most common phenotype related to telomerase mutation is pulmonary fibrosis. Objective To investigate the associations of both TERT and telomerase RNA component C with disease progression in patients with interstitial lung diseases (ILDs), which include idiopathic pulmonary fibrosis (IPF), and to compare results between patients with ILD and control. Patients and methods A total of 46 patients with different types of ILDs were enrolled as well as 15 healthy persons as control. Whole blood sample was obtained from both patients and healthy control for detection of expression of telomerase gene by quantitative real-time PCR. Results There was a significant negative correlation between telomerase reverse transcriptase (h-TERT) and partial pressure of oxygen (r=−23, P=0.03). Both h-TERT and telomerase reverse transcriptaseRNA component (h-TERC) were relatively more expressed in patients with IPF with pulmonary hypertension, whereas there was a significant elevation of h-TERT relative expression in patients with IPF with honeycombing high-resolution computed tomography pattern in comparison with those with reticulonodular pattern, with median of 0.85 versus 0.29, respectively. Conclusion Hypoxia may affect DNA damage in the telomere region. Expression of telomerase may take part in pulmonary fibrosis.

Objective This study aimed to implement bronchoscopic C-TBNA service in a tertiary care chest hospital with special emphasis on the diagnostic yield, complications encountered, and learning experience. Patients and methods This cohort study was conducted on 60 patients with bronchoscopic nonvisible extraluminal lesions who have sought bronchoscopic C-TBNA service at the Bronchoscopy Unit of both Ain Shams University Hospital and Giza Chest Hospital during the period from June 2016 to February 2018. Results The overall C-TBNA had a diagnostic yield of 88.3% in which 68.3% were malignant and 20% had sarcoidosis without serious complications recorded except for minor non-life-threatening bleeding in 21.7% of cases. After 6 months of C-TBNA learning experience, the diagnostic yield showed improvement in physicians without previous C-TBNA experience, but without reaching a statistical significance. Also, there were significant reduction in both duration and complications of C-TBNA.

The diaphragm is the principal respiratory muscle, and its dysfunction can prolong the duration of mechanical ventilation. Ultrasonography is a fast, easy, and accurate method of bedside evaluation for diaphragmatic function. In the ICU population, it can quantify normal and abnormal movements in a variety of clinical conditions. Patients and methods A prospective observational study was carried on 32 patients with COPD admitted to the respiratory ICU. Diaphragmatic excursion had been assessed by chest ultrasonography in every mode of mechanical ventilation and was correlated with weaning off mechanical ventilation and other physiological parameters. Results Of 32 patients with COPD included in the study, 24 patients were successfully weaned versus eight patients failed to be weaned off mechanical ventilation. Diaphragmatic excursions in every mode of mechanical ventilation (noninvasive, volume control, bilevel positive airway pressure, and pressure support) were higher in weaned patients with best cutoff values of 1.4, 1.3, 1.5, and 1.6 cm, respectively. Moreover, the diaphragmatic excursions were directly correlated with tidal volumes and inversely correlated with days of mechanical ventilation and rapid shallow breathing index. Conclusion Diaphragmatic displacement assessed by ultrasound is a good predictor for weaning off mechanical ventilation in patients with COPD, as it is sensitive, specific, and accurate. Diaphragmatic excursions are directly related to tidal volumes and inversely related with rapid shallow breathing index and days of mechanical ventilation.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48915404","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}

It may be used for the diagnosis of multiple pleural diseases (pleural effusion, pleural masses, and pneumothorax). It is also used in the diagnosis of diseases caused by lung parenchymal lesions, such as neoplasms, pulmonary embolism, pneumonia, and lung abscesses. Aim This study aimed to evaluate the sonographic features of diffuse parenchymal lung disease (DPLD). Design This was a prospective study. Setting The study was carried out at Fayoum University Hospital in Egypt during the period spanning from January 2017 to June 2017. Patients and methods This study included 120 participants. Sixty of them were diagnosed as having DPLD. For the diagnosis of these cases, we need a full medical history, a detailed clinical examination, spirometry, 6 min walk test, arterial blood gases’ analysis, high-resolution computed tomography, and chest ultrasound. The other 60 were studied as controls. Statistical analysis The data were collected and coded to facilitate data manipulation, and they were double entered into Microsoft Access; the data analysis was performed by using SPSS software, version 18 in Windows 7. The simple descriptive analysis was carried out in the form of numbers and percentages for qualitative data and arithmetic means as central tendency measurement, SDs as measure of dispersion for the quantitative parametric data and the inferential statistic test. Results There was a female predominance with a wide range of age. Most of the cases were nonsmokers, breeding birds, and exposed to biomass. All cases had diffuse bilateral B-lines. There was a negative relation between the Warrick score on the one hand and the B-line number, PaO2, 6 min walk test, and forced vital capacity on the other hand. In contrast, a positive relation was demonstrated between the Warrick score and B-line distance and pleural thickness. Most of the studied patients (71.6%) had irregular and thickened pleura and (51.6%) had an abolished lung sliding. Conclusion Chest ultrasound has a significant role in the diagnosis of DPLD and also in estimating the severity of the disease according to the number and the distance between B-lines. Multiple B-lines in the combination of thickened and irregular pleural line are highly suggestive of DPLD.","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":"45721243","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}
