:To investigate the characteristics of spiral computed tomography (CT), positron emission tomography-computed tomography (PET/CT) and clinical manifestations of talaromycosis to improve the diagnostic level and deepen its recognition in radiology.Radiological, clinical, and pathological manifestations of 15 patients of non-HIV talaromycosis confirmed by bronchofiberscope lung biopsy and/or abscess puncture fluid culture and/or blood culture and/or sputum culture were analyzed retrospectively. All patients underwent chest CT, among them, six had a brain MRI, and six had a PET/CT scan before treatment.On plain CT scan, there were multiple patches and massive consolidation in 6 patients, multiple patchy consolidations and patchy ground-glass opacities in 3 patients, solitary or multiple nodules and masses in 3 patients, multiple cavities and small nodules in 3 patients. Multiple lymphadenectasis appeared in bilateral hila, mediastinum, and neck in 10 patients. In contrast CT scan, the parenchyma of the lesions had a slight enhancement in 10 patients, moderate enhancement in 3 patients, obvious enhancement in 2 patients. Seven cases had bone destruction and hyperplasia, cranial involvement in 1 patient and liver involvement in 3 patients, respectively. On PET/CT, five patients showed elevated standard uptake value (SUV).The radiological manifestations of non-HIV talaromycosis show multiple consolidations, ground-glass opacities, multiple nodules or masses in bilateral lungs, deep-seated enlarged lymph nodes and bone destruction in multiple systems. The final diagnosis should be based on the culture of talaromycosis.
: 探讨螺旋计算机断层扫描 (CT) 、正电子发射断层扫描-计算机断层扫描 (PET/CT) 的特点和临床表现，以提高诊断水平，加深对其在放射学的认识。放射学，临床，回顾性分析经纤维支气管镜肺活检和 (或) 脓肿穿刺液培养和 (或) 血培养和 (或) 痰培养证实的 15 例非HIV距骨真菌病患者的病理表现。所有患者均接受胸部CT检查，其中 6 例在治疗前进行了脑部MRI检查，6 例在治疗前进行了PET/CT扫描。CT平扫，6 例患者出现多发斑块及大片实变，3 例患者出现多发斑片状巩固及斑片状磨玻璃影，3 例患者出现单发或多发结节及肿块，3 例患者多发空洞和小结节。10 例患者双侧纵隔、颈部出现多发淋巴结肿大。CT增强扫描显示病灶实质有轻度强化 10 例，中度强化 3 例，明显强化 2 例。骨质破坏和增生 7 例，颅骨受累 1 例，肝脏受累 3 例。在PET/CT上，5 例患者显示标准摄取值 (SUV) 升高。非HIV距骨真菌病的放射学表现表现为多发性巩固性、磨玻璃影、双侧肺部多发结节或肿块、深部肿大淋巴结及多系统骨质破坏。最终诊断应基于距骨真菌病的培养。
METHODS::Since mid-December of 2019, coronavirus disease 2019 (COVID-19) infection has been spreading from Wuhan, China. The confirmed COVID-19 patients in South Korea are those who came from or visited China. As secondary transmissions have occurred and the speed of transmission is accelerating, there are rising concerns about community infections. The 54-year old male is the third patient diagnosed with COVID-19 infection in Korea. He is a worker for a clothing business and had mild respiratory symptoms and intermittent fever in the beginning of hospitalization, and pneumonia symptoms on chest computerized tomography scan on day 6 of admission. This patient caused one case of secondary transmission and three cases of tertiary transmission. Hereby, we report the clinical findings of the index patient who was the first to cause tertiary transmission outside China. Interestingly, after lopinavir/ritonavir (Kaletra, AbbVie) was administered, β-coronavirus viral loads significantly decreased and no or little coronavirus titers were observed.
METHODS::In December 2019, a novel coronavirus (2019-nCoV) caused an outbreak in Wuhan, China, and soon spread to other parts of the world. It was believed that 2019-nCoV was transmitted through respiratory tract and then induced pneumonia, thus molecular diagnosis based on oral swabs was used for confirmation of this disease. Likewise, patient will be released upon two times of negative detection from oral swabs. However, many coronaviruses can also be transmitted through oral-fecal route by infecting intestines. Whether 2019-nCoV infected patients also carry virus in other organs like intestine need to be tested. We conducted investigation on patients in a local hospital who were infected with this virus. We found the presence of 2019-nCoV in anal swabs and blood as well, and more anal swab positives than oral swab positives in a later stage of infection, suggesting shedding and thereby transmitted through oral-fecal route. We also showed serology test can improve detection positive rate thus should be used in future epidemiology. Our report provides a cautionary warning that 2019-nCoV may be shed through multiple routes.
METHODS::There is a current worldwide outbreak of a new type of coronavirus (2019-nCoV), which originated from Wuhan in China and has now spread to 17 other countries. Governments are under increased pressure to stop the outbreak spiraling into a global health emergency. At this stage, preparedness, transparency, and sharing of information are crucial to risk assessments and beginning outbreak control activities. This information should include reports from outbreak sites and from laboratories supporting the investigation. This paper aggregates and consolidates the virology, epidemiology, clinical management strategies from both English and Chinese literature, official news channels, and other official government documents. In addition, by fitting the number of infections with a single-term exponential model, we report that the infection is spreading at an exponential rate, with a doubling period of 1.8 days.
