Purpose: To explore the clinical and dynamic computed tomography features of coronavirus disease 2019. Methods: We enrolled 24 patients with coronavirus disease 2019 treated at a regional center in Dezhou, China, from January 22 to February 5, 2020, and analyzed data retrospectively. Results: Nineteen cases had close contact with people with coronavirus disease 2019, and five patients denied a travel history in Wuhan City or contact with patients having coronavirus disease 2019. Symptoms were fever, cough, chest tightness, dyspnea, fatigue, and muscle pain. Chest computed tomography showed multiple ground-glass opacities distributed along peribronchial bundles and subpleural areas, often accompanied by bronchiectasis, vascular thickening, and interlobular septal thickening after coronavirus disease 2019 progression. Conclusions: Coronavirus disease 2019 has certain clinical characteristics and typical computed tomography features.

A 22-year-old woman presented with a feeling of chest tightness. Chest computed tomography showed a dendritic shadow in the left segment 1 + 2c, surrounded by hyperlucent emphysematous changes. Bronchoscopy revealed loss of the orifice of bronchus 1 + 2c. Thus a diagnosis of bronchial atresia was made, and a left upper division segmentectomy was performed. Bronchial atresia should be considered in the differential diagnosis of young patients with an abnormal chest shadow. It can be diagnosed based on the characteristic imaging and bronchoscopic findings. Surgery is indicated for symptomatic bronchial atresia and can provide complete amelioration of the condition.

Abstract Objectives: To discuss the prevention and containment of COVID-19 at a general hospital in Shenzhen China; to analyze the epidemiological and clinical characteristics of its confirmed patients, which is intended to provide a model for other hospitals in COVID-19 management.Methods: The General Hospital of Shenzhen University sets up 4 medical zones relative to the COVID-19 prevention and containment. In so doing, the suspected patients classified into different kind of ward receive different treatment (Classified and Separated Treatment). The epidemiological distribution and clinical characteristics of 28 confirmed cases in the hospital were analyzed.Results: There are no medical personnel infected cases, no cross-infection among the patients in the hospital, and no misdiagnosis or missed diagnosis of COVID-19. The majority of cases in the group is from 15 to 60 years old, 25 cases had a definite travel history or close contact history in the epidemic area, and parents and spouses of the confirmed patients are the main contact groups. Fever and respiratory symptoms have a high proportion, 4 diarrhea and 4 asymptomatic cases. Additionally, the decrease of lymphocyte is observed in 8 cases. Chest CT scan shows viral pneumonia in 14 cases，All patients were confirmed by nucleic acid tests.Conclusions: Classified and Separated Treatment facilitates management of COVID-19 in the general hospital. Relative to suspected patients in the general hospital, diagnosis matters more than treatment. Epidemiological history, lymphocyte count, and chest CT scan play an important role as the indicator in early diagnosis of COVID-19.

Novel Coronavirus

The ongoing pandemic of the 2019 novel coronavirus disease (COVID-19) raises a global health crisis, which has resulted in 75,778 confirmed cases with 2130 deaths in China and beyond. Atypical symptom renders it challenging to earlier recognize the 2019-nCoV carrier with the potential ability of equivalent transmission. Therefore, it is needed to gain full spectrum of COVID-19. Here we report clustered COVID-19 cases of person-to-person transmission. The symptoms of typical pneumonia are shared by the two familial members, namely son (Patient 1) and father (Patient 2). Unexpectedly, an influenza-like illness (ILI) is also caused in Patient 3 having close contact with Patient 1 at personal dinner party. Combined with clinical and epidemiological study, chest computed tomography (CT) and molecular diagnosis demonstrate that all the three cases tested positive for COVID-19 with distinct symptoms by human-to-human transmission. To the best of knowledge, it closes in part (if not all), a missing gap of clinical repertoires of COVID-19 outbreaks and underlines the possibility that neglection of cryptic/asymptomatic/mild cold-like syndromes gives biased screen in the earlier stage of COVID-19 cases.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an ongoing global health emergency. At present, patients are the primary source of infection. A randomly diagnosed confirmed case of COVID-19 highlights the importance of computerized tomography of thorax in diagnosing asymptomatic patients. In the early phase of COVID-19, routine screenings miss patients who are virus carriers, and tracking travel history is of paramount importance to early detection and isolation of SARS-CoV-2 cases.

Objective. The aim of this study was to review HIV-negative patients with pulmonary cryptococcosis to analyze the correlations between clinical characteristics and chest computed tomography (CT) findings.Methods. We retrospectively analyzed medical records of 16 HIV-negative patients with pulmonary cryptococcosis diagnosed at our institution, and clinical characteristics of the patients with nodules or masses without ground-glass attenuation (GGA)/consolidation type were compared with those of patients with inclusive GGA or consolidation type.Results. Host status was immunocompromised (81.2%) in most of the patients, and 6 (37.5%) were asymptomatic. The most frequent radiologic abnormalities on chest CT scans were one or more nodules (87.5%), GGA (37.5%), and consolidations (18.8%). Most lesions were located in the lower lung. Levels of hemoglobin and platelets were significantly lower in patients with inclusive GGA or consolidation type. Although the differences were not significant, patients with inclusive GGA or consolidation type tended to have a C-reactive protein level of ≥1.0 mg/dL.Conclusion. If a patient with anemia and thrombocytopenia shows GGA or consolidation in the lung, pulmonary cryptococcosis should be given careful consideration.

The Relationship

Abstract Aim This study mainly evaluates the clinical characteristics and chest chest computed tomography (CT) findings of AFB-positive and AFB-negative pulmonary tuberculosis (PTB) patients to explore the relationship between AFB-positive and clinico-radiological findings. Methods A retrospective analysis of 224 hospitalized tuberculosis patients from 2018 to 2020 was undertaken. According to the AFB smear results, they were divided into AFB-positive pulmonary tuberculosis (positive by Ziehl–Neelsen staining) and AFB-negative pulmonary tuberculosis and patients’ CT results and laboratory test results were analyzed. Results A total of 224 PTB patients were enrolled. AFB-positive (n = 94, 42%) and AFB-negative (n = 130, 58%). AFB-positive patients had more consolidation (77.7% vs. 53.8%, p < 0.01), cavity (55.3% vs. 34.6%, p < 0.01), calcification (38.3% vs. 20%, p < 0.01), bronchiectasis (7.5% vs. 1.5%, p < 0.05), bronchiarctia (6.4% vs. 0.8%, p < 0.05), and right upper lobe involvement (57.5% vs. 33.1%, p < 0.01), left upper lobe involvement (46.8% vs. 33.1%, p < 0.05) and lymphadenopathy (58.5% vs. 37.7%, p < 0.01). Conclusion The study found that when pulmonary tuberculosis patients have consolidation, cavity, upper lobe involvement and lymphadenopathy on chest CT images, they may have a higher risk of AFB-positive tuberculosis.
