The aim of the study was to investigate clinical features of patients with AIDS having respiratory symptoms as initial manifestations and help in the early diagnosis. Eighty-eight patients admitted to the Shanghai Pulmonary Hospital were included in the study. General data, clinical manifestations, laboratory tests, chest computed tomography (CT) imaging features, treatments, and prognosis were analyzed. Peripheral leukopenia, lymphopenia, hypoxemia, and reduced percentage of CD4+ T lymphocytes were found in 25.6%, 43.6%, 27.5%, and 94.9% of the patients, respectively. Pneumocystis jirovecii pneumonia (PCP) was the most frequent cause of opportunistic pulmonary infection. Patients with PCP had more bilateral lung involvement and ground-glass shadow in CT manifestations. A follow-up of the 43 patients transferred to the Public Health Center showed improvement in 27 (62.8%), stabilization in 4 (9.3%), worsening in 1 (2.3%), and death in 11 (25.6%) patients. Detailed medical history recording, screening of human immunodeficiency virus antibody, and flow cytometry would improve the diagnostic efficiency of AIDS in patients with diffuse ground-glass shadow in chest CT. Early and empirical treatment could improve the prognosis.

Introduction. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly contagious disease, and its first outbreak was reported in Wuhan, China. A coronavirus disease (COVID-19) causes severe respiratory distress (ARDS). Due to the primary involvement of the respiratory system, chest CT is strongly recommended in suspected COVID-19 cases, for both initial evaluation and follow-up. Objective. The aim of this review was to systematically analyze the existing literature on CT imaging features of patients with COVID-19 pneumonia. Methods. A systematic search was conducted on PubMed, Embase, Cochrane Library, Open Access Journals (OAJ), and Google Scholar databases until April 15, 2020. All articles with a report of CT findings in COVID-19 patients published in English from the onset of COVID-19 outbreak to April 20, 2020, were included in the study. Result. From a total of 5041 COVID-19-infected patients, about 98% (4940/5041) had abnormalities in chest CT, while about 2% have normal chest CT findings. Among COVID-19 patients with abnormal chest CT findings, 80% (3952/4940) had bilateral lung involvement. Ground-glass opacity (GGO) and mixed GGO with consolidation were observed in 2482 (65%) and 768 (18%) patients, respectively. Consolidations were detected in 1259 (22%) patients with COVID-19 pneumonia. CT images also showed interlobular septal thickening in about 691 (27%) patients. Conclusion. Frequent involvement of bilateral lung infections, ground-glass opacities, consolidation, crazy paving pattern, air bronchogram signs, and intralobular septal thickening were common CT imaging features of patients with COVID-19 pneumonia.

Abstract Purpose: Investigate clinical and CT manifestations of ordinary coronavirus disease (COVID-19) pneumonia.Materials and methods: Patients with ordinary COVID-19 pneumonia (confirmed by RT-PCR) and performed initial chest CT were retrospectively enrolled. Fifty-eight patients were assigned to group 1 (<50 years, n=33) and group 2 (50≥years, n=25) on the basis of age. The clinical data, laboratory results, and imaging findings were evaluated. Imaging features were analyzed and compared across the two groups.Results: On chest CT imaging, 44 (75.9%) patients showed bilateral lung involvement, 14(24.1%) showed unilateral lung involvement, with predominant peripheral distribution (26/58, 44.8%) and mixed distribution (30/58, 51.7%). 445(445/634, 70.2%) lesions occurred in the lung periphery, 189 (29.8%) in the center. There were more lobes involved in group 2(median 4, IQR 3-5) than group 1(median 3, IQR 1.5-4) (P=0.024). Ground glass opacity (GGO) (451/634, 71.1%) and consolidation (157/634, 24.8%) were the main CT findings. Lesions with a maximum diameter greater than 5cm were more common in group 2 (19/25, 76%) than group 1 (12/33, 36.4%) (P=0.003). The CT score of bilateral lungs, right lung, left lung and each lobe in group 2 was significantly higher than those of group 1 (all P < 0.05), except for the middle lobe of the right lung (P=0.979). Conclusions: Ordinary COVID-19 pneumonia on chest CT generally manifested as multiple GGO and consolidation in the bilateral lung, with predominant peripheral or mixed distribution. Older age might be a risk factor for progression in ordinary COVID-19 pneumonia.

Abstract Background Collecting (Bellini) duct carcinoma (CDC) is a highly malignant and rare kidney tumor. We report our 12-year experience with CDC and the results of a retrospective analysis of patients and tumor characteristics, clinical manifestations, and imaging features by computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT. Methods Retrospective examination of tumors between January 2007 and December 2019 identified 13 cases of CDC from three medical centers in northern China. All 13 patients underwent CT scan, among which eight underwent dynamic enhanced CT scan, two underwent PET/CT scan, and one underwent magnetic resonance cholangiopancreatography (MRCP) examination. The lesions were divided into nephritis type and mass type according to the morphology of the tumors. Results The study group included ten men and three women with an average age of 64.23 ± 10.74 years. The clinical manifestations were gross hematuria, flank pain, and waist discomfort. The mean tumor size was 8.48 ± 2.48 cm. Of the 13 cases, six (46.2%) were cortical-medullary involved type and seven (53.8%) were cortex–medullary–pelvis involved type. Eleven (84.6%) cases were nephritis type and two (15.4%) were mass type. The lesions appeared solid or complex solid and cystic on CT and MRI. The parenchymal area of the tumors showed isodensity or slightly higher density on unenhanced CT scan in the 13 cases. PET/CT in two cases showed increased radioactivity intake. Evidence of intra-abdominal metastatic disease was present on CT in nine (69.2%) cases. Conclusions The imaging characteristics of CDC differ from those of other renal cell carcinomas. In renal tumors located in the junction zone of the renal cortex and medulla that show unclear borders, slight enhancement, and metastases in the early stage, a diagnosis of CDC needs to be considered. PET/CT provides crucial information for the diagnosis of CDC, as well as for designing treatment strategies including surgery.

Abstract Background Coronavirus disease (COVID-19) is a respiratory syndrome with a variable degree of severity. Imaging is a vital component of disease monitoring and follow-up in coronavirus pulmonary syndromes. The study of temporal changes of CT findings of COVID-19 pneumonia can help in better understanding of disease pathogenesis and prediction of disease prognosis. In this study, we aim to determine the typical and atypical CT imaging features of COVID-19 and discuss the association of typical CT imaging features with the duration of the presenting complaint and patients’ age. Results The lesions showed unilateral distribution in 20% of cases and bilateral distribution in 80% of cases. The lesions involved the lower lung lobes in 30% of cases and showed diffuse involvement in 58.2% of cases. The lesions showed peripheral distribution in 74.5% of cases. The most common pattern was multifocal ground glass opacity found in 72.7% of cases. Atypical features like cavitation and pleural effusion can occur early in the disease course. There was significant association between increased number of the lesions, bilaterality, diffuse pattern of lung involvement and older age group (≥ 50 years old) and increased duration of presenting complaint (≥ 4 days). There was significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age. Conclusion The most common CT feature of COVID-19 was multifocal ground glass opacity. Atypical features like cavitation and pleural effusion can occur early in the course of the disease. Our cases showed more extensive lesions with bilateral and diffuse patterns of distribution in the older age group and with increased duration of presenting complaint. There was a significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age.

Coronavirus disease 19 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with various clinical manifestations, including skin lesions. In particular, during the COVID-19 pandemic lock-down period numerous chilblain-like lesions, mainly located on the feet, were observed in adolescents. The latter were often asymptomatic or associated with very mild respiratory symptoms. Here, we report three cases of acral nodular lesions in SARS-CoV-2 swab-negative adolescents with histological findings of chronic immune-mediated inflammation and immunohistochemical evidence of SARS-CoV-2 spike glycoproteins in endothelial cells and eccrine sweat glands. In one of these cases, the virus presence was confirmed by electron microscopy.

BACKGROUND : Colloid cysts are one of the rare brain tumours and are mostly located in the anterosuperior portion of the third ventricle, between the fornix and surround of Foramen of Monroe. OBJECTIVES: Ÿ 1.To review the demographic information & analyse clinical manifestations of patients presenting with colloid cyst of third ventricle. Ÿ 2.To analyze the advantages and disadvantages of various surgical approaches Ÿ 3.To assess the surgical outcome in colloid cyst patients operated by any method. MATERIALS AND METHODS: A retrospective study was performed on 16 patients who presented with a colloid cyst and underwent surgery at the Department of Neurosurgery, King George Hospital, Andhra Medical College between 2013-2018. They were evaluated based on clinical ndings and imaging features, surgical approaches used for resection and their outcomes. RESULTS: Sixteen cases of colloid cyst of the third ventricle were operated upon between 2013-2018. There were seven male and nine female patients with their ages varying between 9 and 62 years old. Nine patients were operated on by using a transcortical trans-ventricular approach, four using the anterior trans-callosal approach and, three patients by using an endoscopic approach. In all patients, complete excision of the lesions was achieved. CONCLUSION: Colloid cysts, though benign, present surgical challenges because of its deep midline location. Complete excision of the colloid cyst carries an excellent prognosis. Surgery is a safe and effective treatment option for this benign lesion.

Toxoplasma gondii is a known cause of encephalitis in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients. Toxoplasma pneumonitis is a manifestation of extracerebral toxoplasmosis and can be clinically indistinguishable from other opportunistic infections including Pneumocystis jirovecii pneumonia (PJP) and miliary tuberculosis. In this case report, Toxoplasma pneumonitis and disseminated toxoplasmosis was diagnosed using next-generation sequencing (NGS) and polymerase chain reaction (PCR) assessment. NGS can detect microbial cell-free DNA (cfDNA) circulating in the plasma of over 1,000 pathogens. This case is a rare presentation of Toxoplasma pneumonitis in the absence of neurological symptoms and we discuss the use of NGS of microbial cfDNA and PCR tests that may be utilized for the timely diagnosis of such challenging cases.

Ornidazole-induced encephalopathy (OIE) is seldom seen in the clinic. In this study, we report a new case of a patient who had taken 1,000 mg ornidazole daily for nearly 4 years because of suspected diarrhea and proctitis and presented with subacute symptoms such as unsteady gait, slurred speech, and psychiatric disorder. These symptoms were significantly relieved 3 days after the patient stopped taking ornidazole. When he took this medicine again, however, similar symptoms occurred 4 months later, which were again reduced after 4 days of drug discontinuation. After the second onset, abnormal signals were identified around the aqueduct of the midbrain, around the fourth ventricle, and in the dentate nuclei of the cerebellum bilaterally. After 9 days of drug discontinuation, lesions disappeared in the magnetic resonance imaging (MRI) results. According to the clinical manifestations, imaging features, and the reduced symptoms after drug withdrawal, we clinically diagnosed the patient with OIE. This paper also reviews the literature on OIE. Only five cases (including our case) have been reported, all of whom presented with cerebellar ataxia and dysarthria and three with additional mental symptoms such as agitation and irritability. All five patients had abnormal lesions in the dentate nucleus of the cerebellum bilaterally, among whom four also had lesions in the corpus callosum and three around the periaqueduct of the midbrain. After withdrawal of ornidazole, the symptoms in all patients vanished or were alleviated, and three of them showed reduced or disappeared lesions in a head MRI reexamination. Overall, OIE has rarely been reported. Our case report and literature review show that the lesions in the cerebellum, corpus callosum, and brainstem can be reversed. The main manifestations of the lesions—cerebellar ataxia, dysarthria, and mental symptoms—quickly weaken or disappear after drug withdrawal, with good prognosis. Nevertheless, clear pathogenesis has yet to be further investigated.

Abstract Objective: Novel coronavirus (nCoV, SARS-CoV-2) infection becomes a world-wide epidemic which has complicated and diversified symptoms, but no special treatment. In this study, diagnosis and treatment of family clustering nCoV infection were analyzed.Methods: The Sichuan Suining Central Hospital received 11 patients with confirmed nCoV virus infection from 4 families during January 23rd, 2020 to February 20th, 2020. Their clinical symptoms, treatment conditions and changes of disease state were reviewed in the present study.Results: In all 4 families, there were 1-2 members in each family who had contact with epidemic disease. Clinical manifestations were: 3 cases had debilitation only, 1 case had cough only, 1 case had diarrhea (a child patient of four years old), 5 cases had fever and cough, and 1 case had blood-stained sputum. According to image changes, no image change was observed in 1 child patient. Multiple focal ground-glass opacities were detected from 2 patients and multiple patchy shadows were observed from 8 patients, especially in lung periphery. Complications with basic diseases: there were hypertension in 3 cases, diabetes in 2 cases, and hypertension and diabetes in 1 case. Moreover, there’s one patient who had rheumatic heart disease and received mitral and aortic valve replacement 2 years ago. There’s another one who had depression and suicidal tendency. All 11 cases divided into mild type (1 child patient), moderate type (8 patients), severe type (1 patient) and critical type (1 patient). Treatment: the mild child patient (4 years old) was administrated with 2.75ml lopinavir / ritonavir oral liquid (twice per day) and intravenous drip of 0.17g ribavirin injection (1ml: 0.1g*10pcs/box) every 12h for one week. Meanwhile, the child was asked to take azithromycin orally. 7 moderate patients were treated with intravenous drip of 0.5g ribavirin injection (1ml: 0.1g*10pcs/box) every 12h (twice per day) and two pieces of lopinavir/ritonavior (twice per day) for 7-10 days. In the same time, patients were given with reasonable amount of antibiotics by oral or intravenous drip. 1 severe patient and 1 critical patent were treated with 5,000,000 U recombinant human interferon α2b injection (3,000,000 U/pc) and aerosol inhalation of 2ml sterile water for injection (5ml*50 pcs/ box), twice per day. Besides, they took 2 pieces of lopinavir/ritonavior, twice per day. The whole treatment program lasted for 6-12 days, accompanied with appropriate amount of intravenous drip of antibiotics. The critical patient was also provided with mechanical ventilation. During the treatment, severe and critical patients were treated by resochin for 4-5 days for evident respiratory symptoms. One moderate patient was treated with 2 pieces of lopinavir/ritonavior, twice per day. In the same time, it was administrated by intravenous drip of antibiotics. However, resochin treatment was applied for positive novel coronavirus nucleic acid of respiratory sputum specimen after 11 days of treatment. Discharge: After treatment, patients with body temperatures of all patients recovered to normal level, and respiratory symptoms and digestive tract symptoms relieved significantly, significant coefficient of exudative lesion at lung according to chest CT and negative novel coronavirus nucleic acid of continuous two respiratory sputum specimens (sampling interval was at least 1 day) were allowed to be discharged. Adverse reactions: 4 patients had loose stools and abdominal discomfort, and another 2 cases had diarrhea.Conclusions: SARS-CoV-2 infection have complicated and diversified symptoms, which shall be identified according to epidemic history and novel coronavirus nucleic acid test. In particular, the whole family in which there’s a patient with confirmed SARS-CoV-2 shall be isolated for screening in addition to the patient. The lopinavir/ritonavior administration combined with ribavirin or recombinant Human Interferon (RHI) α2b is effective, accompanied with mild adverse reaction. If lopinavir/ritonavior administration and / or combined with ribavirin and RHI α2b is invalid, adding resochin might be effective.
