Prognostic Value of Chest X-ray and CT Defined Large Mediastinal Adenopathy in High Risk Pediatric Hodgkin Lymphoma (COG AHOD0831)

SummaryAll X-rays requested by psychiatrists in-training during 1982 and performed by the Department of Radiology of a large mental hospital were analysed. Forty-five per cent of all requests were marked routine, and the majority of these were for chest X-rays; only 4% of these revealed significant abnormality and no patient under the age of 55 had a significant abnormality on routine chest X-ray. All routine skull X-rays were normal. One-third of the long-stay hospital population accounted for one-quarter of the overall workload of the department. It is recommended that: requests for routine skull X-rays be abandoned, and that routine chest X-rays for patients below the age of 55 be restricted to high-risk groups such as immigrants, those on steroids, etc. The financial implications of such a policy are discussed.

Radiological Measurements

Background. Sternal wound complications are serious events that occur after cardiac surgery. Few studies have investigated the predictive value of chest X-ray radiological measurements for sternal complications. Methods. Several perioperative radiological measurements at chest X-ray and clinical characteristics were computed in 849 patients deemed at high risk for sternal dehiscence (SD) or More than Grade 1 Surgical Site Infection (MG1-SSI). Multivariable analysis identified independent predictors, whilst receiver operating characteristics (ROC) curve analyses highlighted cut-off values of radiological measurements for the prediction of both complications. Results. SD occurred in 8.8% of the patients, MG1-SSI in 6.8%. Chronic obstructive pulmonary disease (COPD) was the only independent predictor for SD (Odds Ratio, O.R. 12.1; p < 0.001); proximal sternal height (PSH) was the only independent protective factor (O.R. 0.58; p < 0.001), with a cut-off value of 11.7 mm (sensitivity 70.5%, specificity 71.0%; ROC area under the curve (AUC) = 0.768, p < 0.001). Diabetes mellitus (O.R. 3.5; p < 0.001) and COPD (O.R. 21.3; p < 0.001) were independent predictors for MG1-SSI; indexed proximal sternal height (iPSH) was as a protective factor (O.R. 0.26; p < 0.001) with a cut-off of 5.97 mm (sensitivity 70.2%, specificity 69.0%; ROC AUC = 0.739, p < 0.001). No other radiological measurements were independently correlated with SD or MG1-SS (p = N.S.). Conclusion. PSH and iPSH at preoperative chest X-ray may act as indicators of high risk for sternal wound complications, allowing for early preventative measures.

Chest X Ray

The sudden increase in COVID-19 patients is a major shock to our global health care systems. With limited availability of test kits, it is not possible for all patients with respiratory infections to be tested using RT-PCR. Testing also takes a long time, with limited sensitivity. The detection of COVID-19 infections on Chest X-Ray can help isolate patients at high risk while awaiting test results. X-Ray machines are already available in many health care systems, and with many modern X-Ray systems already installed on the computer, there is no travel time involved in the samples. In this work we propose the use of chest X-Ray to prioritize the selection of patients for further RT-PCR testing. This can be useful in a hospital setting where current systems have difficulty deciding whether to keep the patient in the ward with other patients or isolate them from COVID-19 areas. It may also be helpful in identifying patients with high risk of COVID with false positive RT-PCR that will require repeated testing. In addition, we recommend the use of modern AI techniques to detect COVID-19 patients who use X-Ray imaging in an automated manner, especially in areas where radiologists are not available, and help make the proposed diagnostic technology easier. Introducing the CovidAID: COVID-19 AI Detector, a model based on a deep neural network of screening patients for proper diagnosis. In a publicly available covid-chest x-ray-dataset [2], our model provides 90.5% accuracy with 100% sensitivity (remember) to COVID-19 infection. We are greatly improving the results of Covid-Net [10] on the same database.

Mediastinal Adenopathy

Abstract Background People coinfected with tuberculosis (TB) and human immunodeficiency virus (HIV) are 20–37 times more likely to develop active TB disease than non-HIV-infected people. Syndemic interaction between HIV and TB epidemics has made testing for TB a must for HIV-infected people and vice versa. We present the case of a young male diagnosed with HIV infection, due to mandatory HIV testing for all TB cases in Romania. Case presentation A 30-year-old man was hospitalized for fever, chills and productive cough not influenced by previous antibiotic home treatment. He was admitted with tachycardia and bilateral presence of coarse crackles in lower pulmonary areas. Chest X-ray suggested bilateral bronchopneumonia; the results from blood tests showed inflammation, leukocytosis and anaemia. Hemocultures were negative. Under wide-spectrum antibiotic treatment, his general condition partially improved, but on the seventh day, chest X-ray revealed abscess in the left inferior lobe and the progression of previous lesions. Chest computed tomography revealed multiple large consolidation areas in both lung areas, a 13 cm diameter abscess and multiple mediastinal adenopathy of 2–4 cm in diameter. Acid fast bacilli smear from sputum was positive. After the diagnosis of pulmonary TB, anti-TB treatment was started; the patient was subsequently diagnosed with HIV infection. He received specific anti-TB treatment, and 3 weeks later, retroviral treatment was initiated. Clinical evolution was favourable and radiological appearance improved. In addition, he did not present any adverse effects of therapy. Conclusions HIV testing for all TB cases is a must because HIV-TB coinfection raises important diagnostic and treatment problems.
