Introduction A radiologic finding takes a prominent place in establishing the diagnosis of pulmonary thromboembolism. It may rather vary in appearance, depending on the size of the obturated blood vessel. Changes in the pulmonary parenchyma develop within 24 hours after pulmonary thromboembolism attack occurs. In microembolism, the radiologic finding appears normal. Triangle-shaped shadows characteristic for pulmonary thromboembolism may appear as either round or oval on computerized CT scan. In standard chest X-ray finding, these lesions look like tumorous ones. Results Over the period from 1995 to 1997, there were 421 patients treated for pulmonary thromboembolism at the Institute of Pulmonary Diseases in Sremska Kamenica (Yugoslavia), whereas 3.09 % of them presented with an oval shadow in a standard chest X-ray or CT finding. The analysis performed in 1981 revealed that majority of patients with pulmonary thromboembolism (11.4%) had round-shaped shadows. Discussion Any round-shaped shadow discovered by both standard chest X-ray and CT findings should be carefully investigated because differential diagnostics includes a variety of diseases. Conclusion A round-shaped or oval lung shadow seen in standard chest X-ray or CT finding should be suspected for lung cancer. Patients are therefore submitted to aggressive diagnostic procedures. Pulmonary thromboembolism should also be thought of in order to initiate proper treatment in time.

1610 Background: Low dose computed tomography (LDCT) scans have reduced lung cancer deaths by 20.3% in high risk populations, although there is an unknown balance between the benefits and harms of LDCT scans as a screening tool. Our purpose was to compare health-related QOL issues among lung cancer patients who were initially detected by LDCT scans; 4 comparison groups included: lung cancer diagnosed by a screening chest X-ray, as an incidental finding from procedures taken for other medical reasons, or based on symptoms indicative for lung cancer and routinely diagnosed, and individuals who were LDCT screened but found no lung cancer (controls who participated in Mayo’s lung cancer CT screening trial). Methods: A total of 1,658 lung cancer patients (cared at Mayo Clinic) in the 4 groups (37, 151, 389, and 1081 respectively) and 488 controls were compared on following patient-reported outcomes (collected via validated tools): overall QOL, four symptoms (cough, pain, dyspnea, fatigue), mental/ physical/ emotional/ social/ spiritual QOL, and other concerns (e.g., family/ friends/ financial/ legal). A clinically significant deficit was defined as at least 10-points in difference (or <50 points) on a 0-100 scale. The rates of deficits were compared via Fisher’s exact tests and average QOL values via Kruskal-Wallis tests. Results: Overall QOL and individual symptoms were significantly worse (p<0.05) in all lung cancer groups than in controls, except for pain. LDCT-screened patients reported the greatest deficit among the 4 lung cancer groups in physical (41%), emotional (24%), social (38%), and spiritual QOL (24%); whereas chest X-ray detected patients had the least deficit in overall QOL (22%) and pain (32%). All 4 lung cancer groups experienced much worse fatigue (52-64%) than the controls (32%). Conclusions: Our preliminary results suggest that LDCT-screening detected lung cancer patients reported a different QOL profile from other lung cancer patients and non-lung cancer controls. The clinical course, smoking behavior, and QOL related health issues associated with LDCT screening for lung cancer warrant thorough investigation.

Abstract Acute lower respiratory infection is the leading cause of child death in developing countries. Current strategies to reduce this problem include early detection and appropriate treatment. Better diagnostic and therapeutic strategies are still needed in poor countries. Artificial-intelligence chest X-ray scheme has the potential to become a screening tool for lower respiratory infection in child. Artificial-intelligence chest X-ray schemes for children are rare and limited to a single lung disease. We need a powerful system as a diagnostic tool for most common lung diseases in children. To address this, we present a computer-aided diagnostic scheme for the chest X-ray images of several common pulmonary diseases of children, including bronchiolitis/bronchitis, bronchopneumonia/interstitial pneumonitis, lobar pneumonia, and pneumothorax. The study consists of two main approaches: first, we trained a model based on YOLOv3 architecture for cropping the appropriate location of the lung field automatically. Second, we compared three different methods for multi-classification, included the one-versus-one scheme, the one-versus-all scheme and training a classifier model based on convolutional neural network. Our model demonstrated a good distinguishing ability for these common lung problems in children. Among the three methods, the one-versus-one scheme has the best performance. We could detect whether a chest X-ray image is abnormal with 92.47% accuracy and bronchiolitis/bronchitis, bronchopneumonia, lobar pneumonia, pneumothorax, or normal with 71.94%, 72.19%, 85.42%, 85.71%, and 80.00% accuracy, respectively. In conclusion, we provide a computer-aided diagnostic scheme by deep learning for common pulmonary diseases in children. This scheme is mostly useful as a screening for normal versus most of lower respiratory problems in children. It can also help review the chest X-ray images interpreted by clinicians and may remind possible negligence. This system can be a good diagnostic assistance under limited medical resources.

Severe pneumonia is the actual problem of present respiratory medicine due to the pronounced impact on mortality and economic expenses of health care. For this reason the aim was to study the regional predictors of fatal severe pneumonia with subsequent development of guidelines for optimizing various aspects of diagnosis and treatment of these group of patients. Retrospective analysis of 62 case histories of admitted patients, who died from severe pneumonia during the calendar year, was performed. The results showed that lethal outcomes of severe pneumonia mostly occur in intensive care units. Analysis of performed laboratory and instrumental diagnostic procedures was conducted to reveal the most significant prognosis markers. The main mistakes in administering medications, firstly antimicrobial, were analyzed. Antibiotic therapy was proclaimed completely optimal only in 18% of cases. The analysis allows to make conclusions about the need for rational minimization of diagnostic complex for hospitalized patients with severe pneumonia with mandatory measurement of oxygen saturation, sputum study and chest X-ray in two projections directly on the first day. Along with timely correction of treatment these methods will allow optimizing the total cost of treatment. Ceftriaxone is a leading administered drug in severe pneumonia with lethal outcomes. Appearingly, first of all, it is determined by the absolute predominance of cheap generic drug forms in pharmaceutical market which do not provide adequate clinical efficiency. Underrated high potential of semisynthetic aminopenicillins in severe pneumonia treatment was identified.

Case Report 10 days before admission a 45-year old female experienced general weakness, and T 38oC. During that period she had no cardio-respiratory nor neurological complaints, and the temperature varied between 37.5oC and 38oC. Her medical history was unremarkable, without immunodeficiency. The day before admission she presented with left arm paresis and during the next day it progressed to paralysis. She had no headache. On admission the following diagnostic procedures were performed: the cranial CT scan showed two lesions (possibly meta lesions). Chest X-ray was normal. WBC=15x109/L, ESR= 90/120. On the second day following admission brain MRI showed multiple abscesses in both hemispheres, mostly in the gray/white junction. High doses of IV metronidasol, cephtriaxon and cipfloxacin were administered without obtaining specimens for micro- biological diagnosis. In next two days she developed coma, respiratory insufficiency and septic temperature. Brain surgery was not performed due to severe involvement of the brain with multiple abscesses. Repeated chest X-ray revealed bilateral pneumonia. A lethal outcome occurred on the third day, regardless of all efforts. Autopsy showed multiple brain abscesses as well as on the lungs and liver. A beta-hemolytic streptococcal infection was established. Conclusions Prevention includes treatment of the infection source. The classic triad of headache, fever and focal deficit occur in less than 50% of patients. Even in such cases brain abscess must be reconsidered. CT appearance of brain abscess is similar to that of neoplastic and other infectious and non infectious deseases - especially in the stage of early cerebritis. If the CT findings are not clear, MRI should be performed.

ObjectivesThe objectives of this study are to identify the characteristics of febrile gynecologic oncology patients and to evaluate the utility of common diagnostic procedures used to assess the etiologies of their fevers.Methods/MaterialsRetrospective data were collected for 200 consecutive patients admitted to the gynecologic oncology service at 1 institution between January 2008 and December 2012 for a diagnosis of fever. Data were collected using contingency tables, and the χ2test was used as appropriate.ResultsOf the patients admitted for evaluation of fever, 142 (71%) of 200 had a documented fever during hospitalization. The most common etiologies of fever in this population were urinary tract infections (28%) and bloodstream infections (27%), whereas 24% of those admitted for fever did not have a source identified. Abdominal/pelvic computed tomography (CT) scans established the etiology of fever in 53 (60%) of the 89 patients tested, whereas chest x-ray and chest CT were diagnostic for 6% and 21%, respectively. Blood and urine cultures were diagnostic in 29% and 32% of cases, respectively. Patients admitted within 30 days of surgery had a higher percentage of wound infections (38% vs 10%,P< 0.001) as compared with those admitted for more than 30 days after surgery.ConclusionsThe initial evaluation of the febrile gynecologic oncology patient without obvious source by history and examination should include urinalysis with reflex culture and blood cultures. Abdominopelvic and chest CT may be useful when fever persists and initial assessment is unrevealing. Chest x-ray is commonly done but infrequently diagnostic. Wound exploration may be important in patients with fevers for more than 30 days after surgery.

This work presents a fully automatic system for the screening of chest X-ray images from portable devices under the analysis of three different clinical categories: normal, pathological cases of pulmonary diseases with findings similar to those of COVID-19, and COVID-19 cases. Our methodology was validated using a dataset retrieved specifically for this study, which was provided by the Radiology Service of the Complexo Hospitalario Universitario A Coruña (CHUAC). Despite the poor quality conditions of chest X-ray images acquired by portable devices, satisfactory results were obtained, demonstrating the robustness and great potential of the proposed system to help front-line clinicians in the diagnosis and treatment of patients with COVID-19.


On an example of a clinical case in a patient with drug addiction, the reviewed clinical and chest X-ray features of community-acquired pneumonia, the diagnostic algorithms and the differential diagnostics are based on the recommendations of the Ukrainian Association of Pulmonology. The treatment strategy of the patient in the conditions of an ambulatory are described. Community-Acquired pneumonia acquired by intravenous drug use is characterized by a severe course, febrile body temperature, severe specific lung disease. On the example of this clinical case, the importance of express diagnostics of pneumonia at the ambulatory stage wasconfirmed to determine the correct tactics of patient management.

Unusual Detection of Tuberculosis in a Woman with Down's SyndromeA woman with Down's syndrome (DS) had sub-febrile temperature, nodular/patchy shadows on the chest X-ray over the right pulmonary base, and a history of recurrent respiratory infections. She was pale, asthenic, uncommunicative, mildly anemic and the erythrocyte sedimentation rate was 80/first hour. The tuberculin skin test (TST) PPD3 was negative. Mycobacterium tuberculosis was isolated from oral mucosal brushing, sensitive to the first line anti-tuberculosis drugs. Patients with DS and other mental disabilities need special care and attention during diagnostic procedures for tuberculosis (TB).
