Aim To evaluate the role of chest US in the diagnosis of peripheral thoracic lesions. Patients and methods A prospective interventional analytical study was included: 40 adult patients with peripheral thoracic lesions. Transthoracic US (Philips Affinity 50 G U/S, made in Germany) was performed using a linear 5–10-MHz probe for examination of the thoracic wall and the parietal pleura, whereas a 2–5-MHz convex probe was used to examine the visceral pleura, pleural effusion, and lung parenchyma. US-guided core biopsy (Tru cut needle 16 G×10 cm), fine-needle aspiration, or both were performed. Different diagnostic procedures such as bronchoscopy, thoracoscopy, or computed tomography-guided biopsy were done to approach the final confirmatory histopathological diagnosis. Results The final confirmatory diagnosis was approached in 38/40 (95%) patients, while 2/40 (5%) patients were undiagnosed due to morbidity or discharge. The frequent transthoracic US findings were pleural effusion (82.5%), pleural thickening (52.5%), and lung collapse (47.5%). While lung abscess (2.5%) and lung nodules (2.5%) were less-frequent findings. Regarding the diagnostic procedure, 11/38 patients of the studied population were diagnosed by US-guided biopsy, 16/38 cases were diagnosed by US-guided aspiration, and 2/38 cases were diagnosed by both US-guided biopsy and aspiration. Moreover, 1/38 cases were diagnosed by computed tomography-guided biopsy because the result of US-guided biopsy was inconclusive. Fiber-optic bronchoscopic biopsy was carried out in 2/38 patients who had endobronchial central lesion. Another 5/38 cases were diagnosed by thoracoscopic biopsies after a trial of US-guided biopsy failure. Transthoracic US had a diagnostic utility of 83, 67, 97, and 25% sensitivity, specificity, positive, and negative predictive value, respectively. Conclusion Transthoracic US is a practical, cheap, and safe method for diagnosis of peripheral lung lesions and pleural diseases.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83121384","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}

As a result, the purpose of this work was to study the efficiency and safety of using mini bronchoalveolar lavage (mini-BAL) samples to diagnose recently developed lung infiltrates in mechanically ventilated patients. Aims This work aims to evaluate the role of BAL cultures sampled using the mini-BAL maneuver to diagnose recently developed lung infiltrates in patients who are being ventilated mechanically. Patients and methods Mini-BAL and microbiological cultures were to evaluate 30 mechanically ventilated patients with recently developed lung infiltrates. The outer protective catheter was a Nelaton catheter size 18 FG, while the inner catheter was an infant ryle catheter size FG-10. Instead of using the prepackaged catheters, the outer protective catheter was blocked by sterile K-Y gel. Results Klebsiella spp. are the most commonly isolated bacterial (44.4%) while Candida spp. (23.3%) are the most commonly isolated fungal organism in mechanically ventilated patients. Some patients had more than one isolated organism: Bimicrobial 16.7% and polymicrobial 26.7% while unimicrobial 46.7%. There was a statistically significant relationship between microbiology and clinical pulmonary infection score among the included patients at P value of 0.003.

Aim To assess the usefulness of ultrasonography compared with capnography and chest radiography in confirmation of correct endotracheal tube position in ICU patients. Patients and methods Fifty patients in need for intubation were included in this study. All patients were subjected immediately after intubation to the following to confirm correct endotracheal intubation: clinical evaluation, neck ultrasound, chest ultrasound, and chest radiographs. All methods were compared with capnography, the gold standard method for confirmation. Results Successful endotracheal intubation was confirmed by the presence of three successive waves in the capnography. This was achieved in 48 (96%) of cases (endotracheal tube), and in two (4%) cases, the tube was falsely placed in the esophagus. Direct localization of intubation by neck ultrasound had 97.7% sensitivity and 100% specificity to confirm correct intubation. On the contrary, indirect localization of the tube by chest ultrasound had 93.7% sensitivity and 100% specificity. Although localization of the tube by chest radiography has 97.8% sensitivity, it took longer time to be done in such critical casas (29236.44 ± 768.27 s).

Diaphragmatic performance is an issue that is not fully studied in different COPD phenotypes. Aim To assess diaphragmatic performance by chest ultrasound (US) in patients with two COPD phenotypes admitted to respiratory ICU with an acute exacerbation and to assess its relation to outcome. Patients and methods US assessment of diaphragm position, excursion, inspiratory time, velocity, thickening fraction, and excursion-time (E-T) index was done for 100 patients with COPD with two phenotypes, that is, chronic bronchitis (CB) and emphysema (E), who were admitted at the respiratory ICU of Abbassia Chest Hospital. Assessment was done for all patients within 24 h of admission. Primary end point was the need for mechanical ventilation (MV) and secondary end point was discharge or ICU mortality. Results Position of the diaphragm was at the –six to eight intercostal space, with mean of 7.114 ± 0.404, in the E group and at the –five to seven intercostal space, with a mean of 5.946 ± 0.524, in the CB group, with P value less than 0.001. There was a higher velocity in E (3.324 ± 1.151 cm/s) compared with CB (2.757 ± 1.023 cm/s), with P=0.011, and a higher expiratory thickness in CB (3.312 ± 0.806) versus E (2.584 ± 0.786 mm), with P value less than 0.001. Regarding the need for MV, 62 (62%) cases required MV (nine noninvasive mechanical ventilation and 53 invasive mechanical ventilation). The need for MV was higher in E compared with CB group (35/50 cases, 70%, and 27/50 cases, 54%, respectively; P<0.001). There was a significant shorter inspiratory time and a lower E-T index in both phenotypes among patients who required MV (P=0.007 and 0.045, respectively). The cutoff value of the inspiratory time and the E-T index in predicting the need to MV was less than 0.65 s and less than 1 cm/s, respectively. Conclusion US assessment of the diaphragm during acute COPD exacerbations may help anticipate the need for MV. The need of MV was related to a shorter inspiratory time (cutoff point <0.65 s) and a lower E-T index (cutoff point <1 cm/s). There was no difference between CB and E phenotypes in this aspect.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80783330","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}

HF is classified into three groups: HFpEF, HFmrEF, and HFrEF according to ESC. SDB is classified according to the central apnea–hypopnea index and obstructive apnea–hypopnea index and their proportions into total apnea and hypopnea index into: OSA, coexisting OSA-CSA (predominantly OSA or CSA), and CSA. Results Statistically significant higher Mallampati score in those with SDB versus those without SDB. STOP-BANG questionnaire was the most sensitive SDB prediction score followed by Berlin score and the least was ESS. Berlin score and ESS were more specific than the STOP-BANG score. Statistically significantly lower left ventricular EF was observed in SDB patients in comparison with patients without SDB. There was significantly higher NC in OSA patients versus coexisting OSA/CSA either predominantly OSA or CSA. Significant higher BMI and Mallampati score in OSA group in comparison to coexisting OSA/CSA predominantly CSA patients. Significant lower left ventricular EF was found in patients with coexisting OSA/CSA whether predominantly CSA or OSA versus LVEF in OSA patients. Significant association between SDB and HF types (OSA was significantly associated with HFpEF). Significant differences between OSA and coexisting OSA/CSA predominantly OSA as regards AF. Conclusions Despite optimized therapy, SDB was prevalent in chronic compensated HF patients (82.5%). Among all studied patients, 40% suffer from obstructive sleep apnea, while 42.5% suffer from coexisting OSA/CSA. SDB in HF patients was best predicted using the STOP-BANG questionnaire, while Berlin and ESS were most accurate. SDB in HF may be predicted by higher Mallampati scores and lower LVEF. OSA is more prevalent in chronic HF patients who have large BMIs, neck circumferences, and Mallampati scores. HFrEF and HFmrEF are the only two forms of HF that are associated with OSA/CSA.

Globally, there have been gains across the HIV testing and treatment cascade. The greatest contributor to the illness and deaths in persons infected with HIV is pulmonary disease. Aims The aim was to study the pattern of respiratory manifestations in HIV-infected patients among a sample of Egyptians. Settings and design A prospective, observational study. Patients and methods This study recruited 121 HIV patients with respiratory system involvement admitted to Abbassia Fever Hospital or Abbassia Chest Hospitals between December 2017 and March 2020. Clinical assessment included demographic data, history of chest symptoms, and comorbidities and local and general examination. Chest imaging was requested/reviewed, and procedures were performed as required. Laboratory assessment included CD4 count, and microbiological examinations of sputum and pleural fluid if found. Statistical analysis used SPSS program (Statistical Package for the Social Sciences) software, version 18.0. Results Of the participants 62 % have been receiving or previously received antiretroviral treatment. Cough was the most frequent symptom in 91.7%. Pleural collection was the most frequent radiological finding on chest radiology in 23% of patients. Tuberculosis was commonly a concomitant infection in 29.7% of patients.
