A total of 115 convalescent inpatients with COVID-19 were enrolled. According to the results of scans of lung lesions via computed tomography (CT), the patients were divided into mild, moderate, and severe groups. The clinical data of the patients were collected, including age, gender, finger pulse oxygen pressure, ventricular rate, body temperature, etc. The correlation between the clinical indicators and the lesions of high-resolution CT (HRCT) and bronchiectasis was analyzed. Among the 115 patients, 82 had no bronchiectasis and 33 had bronchiectasis. The bronchodilation-prone layers mainly included the left and right lower lobe of the lung. The probability of branching in the inflamed area was greater than that in the noninflamed area in patients with COVID-19. There were significant differences in gender, CT lesion range, and number of incidents of bronchiectasis between noninflamed and inflamed areas (P < 0.05). Moreover, there were significant differences in age, total proportion of CT lesions, volume of CT lesions, and total number of patients with bronchiectasis among the three groups (P < 0.05). CT lesion range was positively correlated with the total number of patients with bronchiectasis and patient age (respectively, r = 0.186, P < 0.05; r = 0.029, P < 0.05). The lesion range in HRCT images of lungs in patients with COVID-19 is correlated with bronchodilation. The larger the lesion, the higher the probability of bronchiectasis and the more incidents of bronchiectasis.

Objective To observe the evolution of chest high-resolution computed tomography (HRCT) manifestations in 105 patients with coronavirus disease 2019 (COVID-19). Methods One hundred five patients with confirmed COVID-19 were enrolled from 11 January to 9 February 2020. Sequential chest HRCT examinations were performed. Five stages were identified from the onset of initial symptoms: 0–3, 4–7, 8–14, 15–21, and >21 days (Stages A–E, respectively). A semi-quantitative CT scoring system was used to estimate the sum of lung abnormalities in each stage. Results In total, 393 CT scans were collected. The patients underwent 3.8 ± 1.5 CT examinations. Multiple lobes were involved in most cases. The proportion of consolidation and the total CT score gradually increased from Stage A to C and gradually decreased from Stage C to E. The total CT score of lung involvement was significantly higher in Stage C than in Stages B and D. The CT score of the lower lobe was significantly higher than the corresponding upper and middle lobes in Stages A to D. Conclusions Most patients with COVID-19 had a disease course of >14 days, and the lung lesions in most patients improved after 14 days since initial symptom onset.

Background:Despite the fact that the introduction of biological disease-modifying antirheumatic medicines (bDMARDs) and the early start of treatment for rheumatoid arthritis (RA) can effectively stop the inflammatory process in RA, a fairly large number of patients continue to experience joint pain [1]. It is assumed that in some cases, joint pain in patients with RA is not associated with the inflammation, so it requires consideration of the possibility of using alternative strategies for the treatment of RA.Objectives:The aim of the research is to study the effectiveness of laser therapy in the treatment of RA.Methods:114 patients with RA aged from 32 to 53 years have been monitored for 6 months. There were 82 women (71.9 %) and 32 men (28.1%) among them. The patients were randomly divided into 2 groups. The first group of patients (57 people) received basic medical therapy with methotrexate 15 mg intramuscularly once a week and nonsteroidal anti-inflammatory medicines (NSAIDs) on demand. The dose of methotrexate was selected taking into account the disease activity index DAS 28. The second group of patients (57 people) received basic medical therapy with methotrexate 15 mg intramuscularly once a week and NSAIDs on demand. In addition, the cutaneous low-intensity laser irradiation of the joints was added along the projection of the joint gap in a pulse mode with a wavelength of 0.89 microns. The pulse frequency is 80-1500 Hz, the pulse power is 5 W, the exposure time in the field is 1-2 minutes and the total radiation time per session is no more than 10 minutes [2]. The course of treatment consisted of 10 procedures (the device “Milta F-8 RD”, Russia, Moscow). The course of laser therapy was repeated after 4 weeks. To assess clinical indicators, patients were examined using the SF-36 questionnaire before treatment and 6 months after the start of treatment.Results:The survey after 6 months revealed the significant decrease in the severity of pain on the VAS from the initial average indicator 4.5±0.2 to 3.69±0.2 points (p<0.01) and morning stiffness from 60±5 to 40.8±4 minutes (p<0.01). In the first group, the dynamics of clinical indicators were not statistically significant: the intensity of pain decreased from 4.6±0.2 to 4.2±0.3 points (p>0.05) and the duration of morning stiffness reduced from 62±7 to 58.6±6 minutes (p>0.05). In the second group the decrease in the need for NSAIDs was observed in 21 patients, while in the first group the same was observed only in 10 patients (px2 = 0.020).Conclusion:Laser therapy in the treatment of patients with RA enabled to decrease the frequency of the need for NSAIDs and reduce morning stiffness. We recommend using laser therapy in patients with RA at the second radiological stage as an addition to basic therapy.References:[1]Altawil R et al.

Objective To analyze computed tomography (CT) features of symptomatic patients with coronavirus disease 2019 (COVID-19). Methods Ninety-five symptomatic patients with COVID-19 confirmed by reverse-transcription polymerase chain reaction from 1 May to 14 July 2020 were retrospectively enrolled. Follow-up CT findings and their distributions were analyzed and compared from symptom onset to late-stage disease. Results Among all patients, 15.8% had unilateral lung disease and 84.2% had bilateral disease with slight right lower lobe predilection (47.4%). Regarding lesion density, 49.4% of patients had pure ground glass opacity (GGO) and 50.5% had GGO with consolidation. Typical early-stage patterns were bilateral lesions in 73.6% of patients, diffuse lesions (41.0%), and GGO (65.2%). Pleural effusion occurred in 13.6% and mediastinal lymphadenopathy in 11.5%. During intermediate-stage disease, 47.4% of patients showed GGO as the disease progressed; however, consolidation was the predominant finding (52.6%). Conclusion COVID-19 pneumonia manifested on lung CT scans with bilateral, peripheral, and right lower lobe predominance and was characterized by diffuse bilateral GGO progressing to or coexisting with consolidation within 1 to 3 weeks. The most frequent CT lesion in the early, intermediate, and late phases was GGO. Consolidation appeared in the intermediate phase and gradually increased, ending with reticular and lung fibrosis-like patterns.

Transthoracic Ultrasound

Transthoracic ultrasound (TUS) is a readily available imaging tool that can provide a quick real-time evaluation. The aim of this preliminary study was to establish a complementary role for this imaging method in the approach of interstitial lung diseases (ILDs). TUS examination was performed in 43 consecutive patients with pulmonary fibrosis and TUS findings were compared with the corresponding high-resolution computed tomography (HRCT) scans. All patients showed a thickened hyperechoic pleural line, despite no difference between dominant HRCT patterns (ground glass, honeycombing, mixed pattern) being recorded (p > 0.05). However, pleural lines’ thickening showed a significant difference between different HRCT degree of fibrosis (p < 0.001) and a negative correlation with functional parameters. The presence of >3 B-lines and subpleural nodules was also assessed in a large number of patients, although they did not demonstrate any particular association with a specific HRCT finding or fibrotic degree. Results allow us to suggest a complementary role for TUS in facilitating an early diagnosis of ILD or helping to detect a possible disease progression or eventual complications during routine clinical practice (with pleural line measurements and subpleural nodules), although HRCT remains the gold standard in the definition of ILD pattern, disease extent and follow-up.

Malignant Liver

Inflammatory myofibroblastic tumors (IMT) are a benign tumor entity, which rarely develop in the liver. Surgery is the most common treatment for these lesions as it is difficult to distinguish them from malignant liver tumors and local recurrent growth may occur. IMT is a diagnostic challenge for imaging. Only a limited number of reports of single cases or small number of patients described the imaging features on computed tomography. Reports on IMT appearance on magnetic resonance imaging are scarce. We present a case of IMT of the liver with infiltration of the abdominal wall treated with surgery and describe the imaging features with the use of the hepatobiliary contrast agent, gadoxetic acid (Gd-EOB).

AbstractWe report the case of an adolescent who was presented with long-standing exertional symptoms, and was diagnosed with an anomalous right coronary arterial origin arising above the commissural junction between the left and right aortic sinus, with inter-arterial and intramural compression. The precise origin of this lesion outside the aortic sinuses is unusual, and multi-detector computed tomography gave excellent definition and spatial resolution of the anomalous origin and course. It is crucial to have a high index of suspicion of exertional symptoms, as sudden death may be the first manifestation of an anomalous coronary artery.

Abstract Background A displaced left B1 + 2 accompanied by an anomalous pulmonary vein is a rare condition involving complex structures. There is a risk of unexpected injuries to bronchi and blood vessels when patients with such anomalies undergo surgery for lung cancer. Case presentation A 59-year-old male with suspected lung cancer in the left lower lobe was scheduled to undergo surgery. Chest computed tomography revealed a displaced B1 + 2 and hyperlobulation between S1 + 2 and S3, while the interlobar fissure between S1 + 2 and S6 was completely fused. Three-dimensional computed tomography (3D-CT) revealed an anomalous V1 + 2 joining the left inferior pulmonary vein and a branch of the V1 + 2 running between S1 + 2 and S6. We performed left lower lobectomy via video-assisted thoracic surgery, while taking care with the abovementioned anatomical structures. The strategy employed in this operation was to preserve V1 + 2 and confirm the locations of B1 + 2 and B6 when dividing the fissure. Conclusion The aim of the surgical procedure performed in this case was to divide the fissure between S1 + 2 and the inferior lobe to reduce the risk of an unexpected bronchial injury. 3D-CT helps surgeons to understand the stereoscopic positional relationships among anatomical structures.
