Ultrasonography was used to evaluate 53 patients with equivocal juxta-diaphragmatic and/or lateral densities in chest radiographs. An air bronchogram, fluid bronchogram, and scattered echogenic foci due to residual air in the consolidated lung parenchyma were used as US criteria of pulmonary parenchymal consolidation. One or more of these signs were observed in 39 patients with a clinical or bacteriologic diagnosis of pneumonia. The US air bronchogram was seen in 32 of the 39 patients (82 %), the fluid bronchogram in 37 patients (94%) and the scattered echogenic foci in 30 (77%). In 14 patients, pleural effusion was diagnosed sonographically and verified by aspiration of fluid. The final diagnoses in these cases were pulmonary tuberculosis in 11 patients, staphylococcal empyema in 2, and tuberculous empyema in one patient. It is concluded that US criteria provide a useful differentiation of pulmonary parenchymal consolidation from pleural effusion.

ABSTRACT Background: Conventionally Pleural effusions are suspected by history of pleuritis, evaluated by physical signs and multiple view radiography. Trans-thoracic pleural aspiration is done and aspirated pleural fluid is considered the gold-standard for pleural effusion. Chest sonography has the advantage of having high diagnostic efficacy over radiography for the detection of pleural effusion. Furthermore, ultrasonography is free from radiation hazards, inexpensive, readily available  and feasible for use in ICU, pregnant and pediatric patients. This study aims to explore the diagnostic accuracy of trans-thoracic ultrasonography for pleural fluid detection, which is free of such disadvantages. The objective is to determine the diagnostic efficacy of trans-thoracic ultrasound for detecting pleural effusion and also to assess its suitability for being a non-invasive gold-standard.   Subject and Methods: This retrospective study of 4597 cases was conducted at pulmonology  OPD-Gulab Devi Teaching Hospital, Lahore from November 2016 to July 2018. Adult patients with clinical features suggesting pleural effusions were included while those where no suspicion of pleural effusion, patients < 14 years and pregnant ladies were excluded. Patients were subjected to chest x-ray PA and Lateral views and chest ultrasonography was done by a senior qualified radiologist in OPD. Ultrasound-guided pleural aspiration was done in OPD & fluid was sent for analysis. At least 10ml aspirated fluid was considered as diagnostic for pleural effusion. Patient files containing history, physical examination, x-ray reports, ultrasound reports, pleural aspiration notes and informed consent were retrieved, reviewed and findings were recorded in the preformed proforma. Results were tabulated and conclusion was drawn by statistical analysis. Results: Out of 4597 cases, 4498 pleural effusion were manifested on CXR and only 2547(56.62%) pleural effusions were proved by ultrasound while 2050 (45.57%) cases were reported as no Pleural effusion. Chest sonography demonstrated sensitivity, specificity, PPV, NPV and diagnostic accuracy 100 % each. Conclusions: Trans-thoracic ultrasonography revealed an excellent efficacy that is why it can be considered as non-invasive gold standard for the detection of pleural effusion.

Objective: To investigate factors associated with recognition and delayed isolation of pulmonary tuberculosis (PTB). Background: Precise identification of PTB in the emergency department (ED) remains challenging. Methods: Retrospectively reviewed PTB suspects admitted via the ED were divided into three groups based on the acid-fast bacilli culture report and whether they were isolated initially in the ED or general ward. Factors related to recognition and delayed isolation were statistically compared. Results: Only 24.94% (100/401) of PTB suspects were truly active PTB and 33.77% (51/151) of active PTB were unrecognized in the ED. Weight loss (p = 0.022), absence of dyspnea (p = 0.021), and left upper lobe field (p = 0.024) lesions on chest radiographs were related to truly active PTB. Malignancy (p = 0.015), chronic kidney disease (p = 0.047), absence of a history of PTB (p = 0.013), and lack of right upper lung (p ≤ 0.001) and left upper lung (p = 0.020) lesions were associated with PTB being missed in the ED. Conclusions: Weight loss, absence of dyspnea, and left upper lobe field lesions on chest radiographs were related to truly active PTB. Malignancy, chronic kidney disease, absence of a history of PTB, and absence of right and/or left upper lung lesions on chest radiography were associated with isolation delay.

Introduction: Radiological manifestation of pulmonary tuberculosis in HIV positive patients is different with HIV negative patients. We aim to determine the differences in chest radiological findings of Pulmonary Tuberculosis among HIV and non-HIV infected patients in HTAA. Materials and method: A retrospective study was conducted in Chest Clinic, Hospital Tunku Ampuan Afzan, Kuantan Pahang. There were 101 chest radiographs with sputum smear-positive retrieved and reviewed. Socio-demographic status and chest radiographs findings were documented and analyzed. Results: Of the 101 patients, 12 patients were HIV positive. Of the 89 HIV negative patients, 96% had consolidation change on chest radiograph, in contrast with HIV positive patients, only 4% among them had this appearance and this is statistically significant (p value less than 0.05). Mediastinal lymphadenopathy is significantly higher (17%) in HIV positive patients compared to HIV negative patients (1%). Normal chest radiographs were more common in HIV positive patients (33%) as compared to HIV negative patients (2%). Conclusion: HIV positive patients with pulmonary tuberculosis exhibit different radiological manifestation on chest radiograph when compared to HIV negative patients.

Background: Pulmonary tuberculosis (TB) is a unique infectious disease that more often results in permanent structural changes in the lung parenchyma. It is by virtue of these changes that the patients even after bacteriological cure continue to suffer the after effects of the disease. Objective of study was to assess the clinico-physiological profile of patients of pulmonary impairment after tuberculosis (PIAT) attending S. N. Medical College, Agra, Uttar Pradesh, India.Methods: Over the time period of 2 years, 350 patients of healed pulmonary tuberculosis were identified and studied about their clinico-physiological profile. This profile included age, sex, category of treatment, pulmonary function test pattern, exercising capacity, exercise tolerance and quality of life.Results: It was found that majority of the patients were males, >60 years of age and had taken Category-II treatment. Most of the patients were having an obstructive pattern on PFT, poor exercise tolerance and exercise capacity and a poor quality of life.Conclusions: Patients of healed pulmonary TB continue to experience respiratory symptoms owing to the permanent anatomical changes in the lung conferred by the disease.

Abstract Background Detection of active pulmonary tuberculosis on chest radiographs (CRs) is critical for the diagnosis and screening of tuberculosis. An automated system may help streamline the tuberculosis screening process and improve diagnostic performance. Methods We developed a deep learning–based automatic detection (DLAD) algorithm using 54c221 normal CRs and 6768 CRs with active pulmonary tuberculosis that were labeled and annotated by 13 board-certified radiologists. The performance of DLAD was validated using 6 external multicenter, multinational datasets. To compare the performances of DLAD with physicians, an observer performance test was conducted by 15 physicians including nonradiology physicians, board-certified radiologists, and thoracic radiologists. Image-wise classification and lesion-wise localization performances were measured using area under the receiver operating characteristic (ROC) curves and area under the alternative free-response ROC curves, respectively. Sensitivities and specificities of DLAD were calculated using 2 cutoffs (high sensitivity [98%] and high specificity [98%]) obtained through in-house validation. Results DLAD demonstrated classification performance of 0.977–1.000 and localization performance of 0.973–1.000. Sensitivities and specificities for classification were 94.3%–100% and 91.1%–100% using the high-sensitivity cutoff and 84.1%–99.0% and 99.1%–100% using the high-specificity cutoff. DLAD showed significantly higher performance in both classification (0.993 vs 0.746–0.971) and localization (0.993 vs 0.664–0.925) compared to all groups of physicians. Conclusions Our DLAD demonstrated excellent and consistent performance in the detection of active pulmonary tuberculosis on CR, outperforming physicians, including thoracic radiologists.
