UNSTRUCTURED Background: From December 2019, the 2019 Novel Coronavirus (2019-nCoV) Pneumonia broke out in Wuhan, China. In this study, we present the finding of serial computed tomography in a female patient with 2019-nCoV. Case presentation: We report a 40-year-old female who presented with the symptoms of fever, chest tightness, and fatigue. She was further diagnosed with 2019-nCoV confirmed by rRT-PCR. In terms of her chest CT findings, patchy consolidation shadows, and ground-glass opacities (GGOs) rapidly progressed in both lungs, peripherally. After treatment, the previous lesions were almost absorbed, leaving the fibrous lesions. Conclusions: If there is a history of fever or contact with the epidemic area, combined with the above CT findings, it is necessary to detect the nucleic acid of new coronavirus in time.

Abstract Background: In December 2019, a cluster of patients with pneumonia of unknown cause was linked to a seafood wholesale market in Wuhan, China. A novel coronavirus was detected, capable of infecting humans, on 6 January 2020 and termed COVID-19. By 16 February 2020, there were 51857 confirmed cases with 2019-nCoV (COVID-19) pneumonia in 25 countries. COVID-19 can also lead to acute respiratory distress syndrome (ARDS).Methods: 149 patients with 2019 Novel Coronavirus (COVID-19)pneumonia(68 males, 81 females, ages 1-89)from 6 research centers in China were diagnosed with positive 2019 Novel Coronavirus(COVID-19)nucleic acids antibodies. And their high-resolution computed tomography(HRCT) imaging datas were evaluated.Results: 136/149(91.3%)patients had a clear history of exposure to Wuhan. Fever (122/149, 81.9%)and cough(83/149, 55.7%)were the most common symptoms. The main imaging characteristics within 4 days of onset included 30(20.13%) cases of pure ground glass opacities (P<0.05), 38(25.50%) cases of GGO with reticulation(P<0.01), 12(8.05%) cases of consolidation(P<0.01). In the 5-8 days group, the main imaging features included 71(47.65%) cases of pGGO(P<0.05), 69(46.31%) cases of GGO with reticulation(P<0.01). In the 9-12 days group, the main feature was 85(57.04%) cases with GGO with reticulation(P<0.01). In the group of 13-16 days group, the main imaging characteristics included 48(32.21%) cases of GGO with reticulation(P < 0.01), 34(22.82%) cases of consolidation(P<0.01).Conclusion: Patients infected with COVID-19 pneumonia show more chest CT characteristics within 5-8 days after the onset of disease. The main manifestations included pGGO, GGO with reticulation, consolidation and GGO with consolidation.

Extracardiac manifestations of constrictive pericarditis, such as massive ascites and liver cirrhosis, often cover the true situation and lead to a delayed diagnosis. A young female patient was referred to this hospital due to a 4-year history of refractory ascites as the only presenting symptom. A diagnosis of chronic calcified constrictive pericarditis was eventually established based on echocardiography, ultrasonography, and computed tomography. Cardiac catheterization was not performed. Pericardiectomy led to relief of her ascites. Refractory ascites warrants thorough investigation for constrictive pericarditis.

Abstract Background Diaphragmatic hernias may occur as either congenital or acquired. The most important cause of acquired diaphragmatic hernias is trauma, and the trauma can be due to blunt or penetrating injury. Diaphragmatic hernia may rarely be seen after thoracoabdominal trauma. Case presentation A 54-year-old Turkish male patient admitted to the emergency department with abdominal pain and dyspnea ongoing for 2 days. He had general abdominal tenderness in all quadrants. He had a history of a stabbing incident in his left subcostal region 3 months ago without any pathological findings in thoracoabdominal computed tomography scan. New thoracoabdominal computed tomography showed a diaphragmatic hernia and fluid in the hernia sac. Due to respiratory distress and general abdominal tenderness, the decision to perform an emergency laparotomy was made. There was a 6 cm defect in the diaphragm. There were also necrotic fluids and stool in the hernia sac in the thorax colon resection, and an anastomosis was performed. The defect in the diaphragm was sutured. The oral regimen was started, and when it was tolerated, the regimen was gradually increased. The patient was discharged on the postoperative 11th day. Conclusions Acquired diaphragmatic hernia may be asymptomatic or may present with complications leading to sepsis. In this report, acquired diaphragmatic hernia and associated colonic perforation of a patient with a history of stab wounds was presented.

Abstract Purpose Bochdalek's hernia is a type of congenital diaphragmatic hernia occurring secondary to a defect in the posterior attachment of diaphragm. This condition commonly presents with respiratory insufficiency in infants. To date, there are less than 100 cases of Bochdalek's hernia presenting in adults published in the literature. The mainstay treatment of Bochdalek's hernia involves reduction of hernial contents back into the peritoneal cavity with a tensionless graft repair closing the diaphragmatic defect. Case Presentation We present an atypical case of the Bochdalek hernia presenting in a previously healthy 16-year-old male who presented to the Accident and Emergency department with a 2-day history of dysphagia and loss of breath. The Bochdalek hernia was confirmed on computed tomography (CT) imaging and the patient underwent surgical repair with Gore-Tex mesh. Conclusion The report shows a rare case of the Bochdalek hernia in a young adult, successfully managed with a laparotomy.

Abstract Background To evaluate the clinical value of the chest CT scan compared to the reference standard real-time polymerase chain reaction (RT-PCR) in COVID-19 patients. Methods From March 29th to April 15th of 2020, a total of 240 patients with respiratory distress underwent both a low-dose chest CT scan and RT-PCR tests. The performance of chest CT in diagnosing COVID-19 was assessed with reference to the RT-PCR result. Two board-certified radiologists (mean 24 years of experience chest CT), blinded for the RT-PCR result, reviewed all scans and decided positive or negative chest CT findings by consensus. Results Out of 240 patients, 60% (144/240) had positive RT-PCR results and 89% (213/240) had a positive chest CT scans. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of chest CT in suggesting COVID-19 were 100% (95% CI: 97–100%, 144/240), 28% (95% CI: 19–38%, 27/240), 68% (95% CI: 65–70%) and 100%, respectively. The diagnostic accuracy of the chest CT suggesting COVID-19 was 71% (95% CI: 65–77%). Thirty-three patients with positive chest CT scan and negative RT-PCR test at baseline underwent repeat RT-PCR assay. In this subgroup, 21.2% (7/33) cases became RT-PCR positive. Conclusion Chest CT imaging has high sensitivity and high NPV for diagnosing COVID-19 and can be considered as an alternative primary screening tool for COVID-19 in epidemic areas. In addition, a negative RT-PCR test, but positive CT findings can still be suggestive of COVID-19 infection.

Abstract Background: Newly approved immunotherapeutic agents, like CTLA-4 inhibitors and antibodies against PD-1, are a promising therapeutic option in cancer therapy. Case presentation: A 74-year-old man, with a history of advanced stage melanoma and treatment with ipilimumab, pembrolizumab and nivolumab, was admitted to the hospital due to respiratory failure with hypoxemia and dyspnoea. He rapidly developed severe acute respiratory distress syndrome (ARDS), which required treatment in the intensive care unit which included mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Computed tomographic imaging (CT) showed signs of a pneumonitis, with an ARDS pattern related to the use of PD-1 antibodies. Treating the patient with high-dose immunosuppressive steroids led to an overall improvement. He was transferred to a rehabilitation hospital and subsequently to his home. Discussion and conclusion: This is a unique case report of a patient suffering a grade 4 adverse event under nivolumab who survived having been treated with ECMO. It highlights the possibility of associated adverse reactions as well as the use of ECMO in palliative care patients. ECMO can be of great success even in patients with malignancies, but careful decision making should be done on a case by case basis.

Abstract Objective: The novel coronavirus pneumonia (COVID-19) has spread rapidly across the globe with the movement of people. How to diagnose COVID-19 quickly and accurately is a concern for all. We retrospectively assessed the clinical characteristics of patients with COVID-19 detected by outpatient screening in areas outside Wuhan, China, to guide early screening outside the epidemic area, to isolate and treat COVID-19-positive patients, and to control the spread of this virus in the region.Results: Among the 213 patients treated in the fever clinic of our hospital, 41 tested positive for novel coronavirus (2019-nCoV) and 172 were negative. Among the positive patients, 13 (31.7%) of the patients had been to Wuhan, while 28 (68.3%) had not been to Wuhan. There were 4 cases of clustering occurrence. The main symptoms exhibited by COVID-19-positive patients were fever (87.8%), cough (68.3%), and expectoration (34.1%). The C-reactive protein (CRP) levels were increased in 35 (85.3%) positive patients; the hydroxybutyrate dehydrogenase in the myocardial zymogram was increased in 22 positive patients (53.6%) and 38 negative patients (22.1%); computed tomography (CT) findings revealed lung lesions in all 41 positive patients (100%).Conclusion: We classified the patient population and analyzed the data to understand the early clinical performance of COVID-19. Our research illustrate that screening for COVID-19 outside Wuhan should focus on early symptoms such as fever and cough, in combination with lung CT findings, epidemiological history, and sputum pathogen detection to determine whether patients need further isolation.

Abstract Background A novel coronavirus (COVID-19) has raised world concern since it emerged in Wuhan, China in December 2019. The infection may result in severe pneumonia with clusters of illness onsets. Its impacts on public health make it paramount to clarify the clinical features with other pneumonias. Methods Nineteen COVID-19 and 15 other patients with pneumonia (non-COVID-19) in areas outside of Hubei were involved in this study. Both COVID-19 and non-COVID-19 patients were confirmed to be infected using throat swabs and/or sputa with/without COVID-2019 by real-time RT-PCR. We analyzed the demographic, epidemiological, clinical, and radiological features from those patients, and compared the differences between COVID-19 and non-COVID-19. Results All patients had a history of exposure to confirmed cases of COVID-19 or travel to Hubei before illness. The median (IQR) duration was 8 (6–11) and 5 (4–11) days from exposure to onset in COVID-19 and non-COVID-19 cases, respectively. The clinical symptoms were similar between COVID-19 and non-COVID-19. The most common symptoms were fever and cough. Fifteen (78.95%) COVID-19 but 4 (26.67%) non-COVID-19 patients had bilateral involvement while 17 COVID-19 patients (89.47%) but 1 non-COVID-19 patient (6.67%) had multiple mottling and ground-glass opacity on chest CT images. Compared with non-COVID-19, COVID-19 presents remarkably more abnormal laboratory tests, including AST, ALT, γ-GT, LDH, and α-HBDH. Conclusions The COVID-19 infection has onsets similar to other pneumonias. CT scan may be a reliable test for screening COVID-19 cases. Liver function damage is more frequent in COVID-19 than non-COVID-19 patients. LDH and α-HBDH may be considerable markers for evaluation of COVID-19.

Background: The pooled prevalence of chest computed tomography (CT) abnormalities and other detailed analysis related to patients’ biodata like gender and different age groups have not been previously described for patients with coronavirus disease 2019 (COVID-19), thus necessitating this study. Objectives: To perform a meta-analysis to evaluate the diagnostic performance of chest CT, common CT morphological abnormalities, disease prevalence, biodata information, and gender prevalence of patients. Methods: Studies were identified by searching PubMed and Science Direct libraries from 1 January 2020 to 30 April 2020. Pooled CT positive rate of COVID-19 and RT-PCR, CT-imaging features, history of exposure, and biodata information were estimated using the quality effect (QE) model. Results: Out of 36 studies included, the sensitivity was 89% (95% CI: 80–96%) and 98% (95% CI: 90–100%) for chest CT and reverse transcription-polymerase chain reaction (RT-PCR), respectively. The pooled prevalence across lesion distribution were 72% (95% CI: 62–80%), 92% (95% CI: 84–97%) for lung lobe, 88% (95% CI: 81–93%) for patients with history of exposure, and 91% (95% CI: 85–96%) for patients with all categories of symptoms. Seventy-six percent (95% CI: 67–83%) had age distribution across four age groups, while the pooled prevalence was higher in the male with 54% (95% CI: 50–57%) and 46% (95% CI: 43–50%) in the female. Conclusions: The sensitivity of RT-PCR was higher than chest CT, and disease prevalence appears relatively higher in the elderly and males than children and females, respectively.

Amiodarone-induced pulmonary toxicity is a critical and potentially fatal side effect of amiodarone. Our study was designed to reveal its clinical features, including KL-6, as an interstitial marker. The medical records of eight patients (five men and three women) with amiodarone-induced pulmonary toxicity, who had been referred to our hospital, were examined. The mean age at the initiation of amiodarone was 48 years (range, 54-87 years) and mean duration of medication prior to the development of pulmonary toxicity was 18 months (range, 7-33 months). Serum KL-6 was elevated in six of the eight patients with a range of 525-2915 U/mL. Chest computed tomography (CT) findings showed non-segmental consolidation and/or ground glass opacity. Foamy macrophages were found in bronchoalveolar lavage (BAL) fluids of all examined patients and in transbronchial lung biopsy (TBLB) specimens in half of the examined patients. We concluded that serum KL-6, chest CT findings, and foamy macrophages in BAL fluids and TBLB specimens will be helpful for the diagnosis of amiodarone-induced pulmonary toxicity.
