Here, we use lung ultrasound to discriminate between causative organisms in correlation with other diagnostic modalities. Methods This descriptive cross-sectional study was carried out on 67 patients diagnosed with atypical pneumonia admitted at Ain-Shams University hospitals in the period from July 2019 to June 2021. Study population was divided into three groups according to the causative agent based on the results of PCR: Group 1 included 23 patients (influenza A), group 2 included 30 patients (COVID-19), and group 3 included 14 patients (atypical organisms). Included patients underwent lung ultrasound scan via a 12-zone scanning protocol and CT scan with 24 h in between. The present study was approved by the ethical committee at our institution. Results The mean age ranged from 39.93 ± 19.26 SD to 60.3 ± 13.02 SD years; 64.17% of them were males. There was also a highly statistically significant difference between the three groups as regard B-lines and thickened pleural line being higher among group 2; 100% of cases had B-lines in their chest ultrasound assessment, while thickened pleural line was found in 53.3% of cases. Dynamic air bronchogram was found with higher percentage in group 3 (71.4%) with a highly significant association. Higher mean Soldati score was associated with more severe disease among cases with viral pneumonia. Conclusions Lung ultrasound may be used as an aiding tool to estimate the etiology of atypical pneumonia. It can be useful during pandemics of acute respiratory diseases for rapid triage and stratification of patients as through calculation of modified Soldati score and detection of the most common finding. Also, modified Soldati score correlates with disease severity.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135342363","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}

Aim To assess the diagnostic yield of combined fine needle aspiration (FNAB) and core needle biopsy (CNB) versus each technique ultrasound-guided in peripheral lung and pleural lesions. Methodology The present study enrolled 30 patients presenting to Alexandria Main University Hospital, with CT scans showing undiagnosed peripheral lung or parietal pleural lesions with or without effusion. A full ultrasound chest assessment was done covering 12 regions. Assessment of the lesion of interest, vascularity was assessed via color Doppler, locating the safest entry site. Real-time US-guided FNAB was done using a spinal needle 22 gauge. Then real-time US-guided CNB using 18 gauge Trucut needle in the same setting. Duration and complications of each procedure were reported. In FNAB, three smears were prepared, fixed in alcohol, and stained with hematoxylin and eosin stain. The remaining sample was fixed in formalin and centrifuged to prepare cell blocks. On the other hand, Trucut needle biopsy specimens were fixed in formalin and processed as paraffin-embedded blocks. Immunohistochemical staining was done. The results were classified into four categories (inadequate, negative, suspicious, and positive for malignancy. Results The diagnostic yield of combined techniques was 96.7% versus 63.3% using FNAB and 96.7% using CNB. The sensitivity of FNAB was 86% while CNB was 95%. The specificity and positive predictive value of both methods were 100%. The negative predictive value of FNAB was 57% versus 80% for CNB in peripheral lung lesions. Duration of US-guided CNB was statistically significantly longer than that of FNAB in both peripheral lung and pleural lesions. No major complications were reported using either technique. Conclusion Combined FNAB and CNB were not superior to CNB alone regarding diagnostic yield but were superior to FNAB. Ultrasound-guided CNB has a superior diagnostic yield over FNAB, with no statistically significant difference regarding associated complications, both techniques are safe. FNAB provided sufficient material for ancillary molecular testing.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635161","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}

Successful implementation of lung cancer screening programs has led to increased detection of peripheral pulmonary lesions (PPL). Robotic-assisted bronchoscopy (RB) is a relatively novel tool used to safely diagnose PPN. Additionally, with the developing precision of personalized medicine and targeted therapy, obtaining adequate tissue for next-generation sequencing (NGS) has become critical to optimizing the medical management of lung cancer. Our aim is to assess the diagnostic yield of RB, identify patient and procedure characteristics associated with performing a diagnostic biopsy, and evaluate the adequacy of tumor cellularity for biomarker identification. Results We performed a retrospective observational study consecutively enrolling 54 adult patients who underwent RB between January 2022 and March 2023. Records were reviewed for medical comorbidities and smoking status. PPL characteristics included size, location, presence of a bronchus sign on mapping computed tomography (CT) scans, distance from airway and pleura on CT, and days between obtaining CT and the bronchoscopy. Procedural factors included the radial endobronchial ultrasound (r-EBUS) view obtained and the sampling method(s) with which a diagnosis was achieved. Records were reviewed for final pathology and the need for further procedures to establish a diagnosis. Samples that yielded non-small cell lung cancer (NSCLC) were sent for an NGS panel if deemed adequate. The panels were reviewed to identify potentially actionable mutations. Multivariable logistic regression was performed to assess patients and lesions characteristics associated with a diagnostic biopsy. We sampled 56 lesions, 45 (80.4%) were from current or former smokers. The overall diagnostic yield was 73.2% and 68.9% for nodules less than 3 cm. Lesions size ranged from 8 mm nodules to 70 mm masses, with an average size 20.3 mm. Mean nodule size from diagnostic procedures was 21.5 mm and 16.9 mm from non-diagnostic ones ( p = 0.04). Logistic regression analysis showed that the presence of a bronchus sign was associated with a diagnostic procedure (OR 19.4, p = 0.023), while lack of a r-EBUS view predicted a non-diagnostic bronchoscopy (OR 0.02, p = 0.013). 28 diagnostic biopsies (68.3%) yielded NSCLC and of the 25 cases that we followed, 22 samples (88%) were adequate for NGS. Conclusions The presence of a bronchus sign on CT and obtaining r-EBUS view during RB were associated with a higher diagnostic yield. RB successfully sampled PPL with adequate tumor cellularity for NGS.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635321","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}

Malignancy and tuberculosis are the two most common etiologies in such patients having completely different prognoses. Therefore, correct diagnosis is very important before starting treatment. This study was planned to study the yield of rigid thoracoscopy in such patients and to observe its associated complications. Furthermore, the difference in the profile of patients with malignancy and tuberculosis was also evaluated. Methods This was a single-center, exploratory, observational study done between 1st May 2021 to 31st December 2022. Patients with undiagnosed exudative pleural effusion defined as exudative pleural effusions as per Light’s criteria with negative Gene X pert and twice negative pleural fluid cytology for malignancy, underwent rigid thoracoscopy for confirmation of their diagnosis. Results A total of 160 patients, who fulfilled our inclusion criteria, were included in our study. Male to female ratio was 1.25:1, with a mean age of 57.3 years. The most common etiology observed was malignancy, seen in 120 out of 160 patients (75%), followed by tuberculosis, which was seen in 27 (17%) patients. A final diagnosis could be made in 158 patients, giving a diagnostic yield of 98.8%. 11.8% showed procedure-related complications without any mortality. Conclusion Rigid medical thoracoscopy has a very high diagnostic yield with few complications. A significant proportion of patients with straw-colored effusion can present with malignancy and vice versa. A few with ADA above 40 were diagnosed as having malignancy. Therefore, tissue-based biopsy with thoracoscopy can be easily performed to make a correct diagnosis with huge future implications in such patients.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135820323","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}

So, the aim of the study was to assess levels of APR such as total leucocytic count (TLC), platelets, neutrophils, neutrophils-to-lymphocyte ratio (NLR), CRP, D-dimer, ferritin, and ESR in patients with CAP and to correlate between their values and disease severity. Methodology The study included 51 patients diagnosed as non-COVID-19 (CAP). Patients were classified into two groups group A (pneumonia only) and group B (pneumonia complicated with empyema/complicated para-pneumonic effusion). All patients underwent clinical evaluation, CURB65, radiological assessment, and blood sampling to measure APR. Results The mean age of patients was 47 ± 17 years. The main symptoms were productive cough (90.2%) and Fever (92.2%).TLC, platelets, neutrophils, CRP, D-dimer, ferritin, and ESR were elevated than normal values. Significant positive correlations were found between the duration of fever and CRP, D-dimer, and ferritin with p values = 0.024, 0.012, and 0.034 respectively.

Methods Our case–control study included a total of 86 participants divided into 2 groups: group I is the case group consisting of 56 patients of sepsis or septic shock and group II (control group) of 30 healthy persons: sex and age-matched healthy individuals. All patients were subjected to assessment of C lectin domain family 2 receptor (sCLEC2), by enzyme-linked immunosorbent assay ELIZA kit, then C2PAC index (a ratio of soluble type C lectin-like receptor 2 level sCLEC-2 and platelet count) was calculated using the platelet count. Results Our study demonstrated that sCLEC-2 levels and C2PAC in group I were higher than in group II ( p value < 0.001), and Klebsiella was the most common organism detected in ICU septic patients; detected in 25 patients (44.6%), there is a statistical significance ( p value 0.045) between sCLEC2 levels and streptococcal infections. It was detected also that the SIC group was 17 patients (30.4%) and the sepsis without coagulopathy group was 39 patients (69.6%). Compared with the sepsis without coagulopathy group, the SIC group was significantly older and had a significantly higher SOFA score, sCLEC-2 levels, and C2PAC index. Lastly, the strong potentiality of using C2PAC as a diagnostic and prognostic marker for sepsis-induced coagulopathy with high statistical significance < 0. 001. Conclusions C2PAC index can be validated as an accurate marker of sepsis-induced coagulopathy with higher sensitivity when using the C2PAC index (82.4%) than using sCLEC-2 (58.8%) and both have the same specificity (89.7%).
