RESUMEN

A 63-year-old male checked in 2 days after he had a shoulder MRI with complaints of a swollen and painful left eye. An anteroposterior X-ray of the orbit showed a foreign body of approximately 2.5 cm in de left maxillary sinus and orbit. 11 years ago, patient built a barn using an automatic staple-gun. He recalls having a little wound on his left cheek. His medical history showed that the man had undergone an MRI for his knee 3 years earlier and another for prostate complaints a year ago. Exact localization of the foreign body was confirmed by a CT scan of the orbit. The extraction of the foreign body has been performed by a combined approach, nasal by the otorhinolaryngologist and orbital by the oral and maxillofacial surgeon. This is the first case report on orbital penetration of a luxated foreign body after 3 elective MRI's.

RESUMEN

BACKGROUND: During the ongoing global outbreak of COVID-19, pregnant women who are susceptible to COVID-19 should be highly concerned. The issue of vertical transmission and the possibility of neonatal infection is a major concern. CASE PRESENTATION: Case 1: A 35-year-old pregnant woman with a gestational age of 37 weeks and 6 days was admitted to our hospital at the point of giving birth. Except for the abnormalities in her chest CT image, she was asymptomatic. She had an uncomplicated spontaneous vaginal delivery, and her infant was discharged home for isolation. Because of the positive result of the maternal swabs for SARS-CoV-2 obtained on the 2nd day after sampling, we transferred the mother to the designated hospital and followed up with her by telephone interviews. Luckily, it was confirmed on February 23 that the newborn did not develop any COVID-19 symptoms after observation for 14 days after birth. Case 2: Another pregnant woman, with a gestational age of 38 weeks and 2 days, was also admitted to our hospital because of spontaneous labor with cervical dilation of 5 cm. Since she had the typical manifestations of COVID-19, including cough, lymphopenia, and abnormal chest CT images, she was highly suspected of having COVID-19. Based on the experience from case 1, we helped the mother deliver a healthy baby by vaginal delivery. On the 2nd day after delivery, the maternal nasopharyngeal swab result was positive, while the infant's result was negative. CONCLUSION: There is still insufficient evidence supporting maternal-fetal vertical transmission for COVID-19-infected mothers in late pregnancy, and vaginal delivery may not increase the possibility of neonatal infection.

RESUMEN

Since asymptomatic infections as "covert transmitter", and some patients can progress rapidly in the short term, it is essential to pay attention to the diagnosis and surveillance of asymptomatic patients with SARS-COV2 infection. CT scan has great value in screening and detecting patients with COVID-19 pneumonia, especially in the highly suspected or probable asymptomatic cases with negative RT-PCR for SARS-COV2. This study aimed to detect incidentally COVID-19 pneumonia on medical imaging for patients consulting for other reasons.

RESUMEN

To describe the chest CT features reported in children with confirmed COVID-19 infection, published in English literature. A systematic review was completed on PubMed, Embase and Scopus databases on the 1st of June 2020 using the PICO strategy. The NIH Quality Assessment Tool was used to assess the quality of the selected articles. The systematic review was evaluated by Case Series Studies and the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA). The extracted data were assessed and compared with those reported in the adult population. Seventy-two articles were retrieved from the database search and screened by the title, abstract and keywords. Eleven articles were deemed eligible for full-text assessment. Nine articles were included for the data extraction and in the final analysis. Chest CT features in children with COVID-19 differ from those in adults. 'Ground-grass opacities' (GGOs) are the most commonly described abnormalities, but closely followed by a combination of GGO and consolidation, not usual in adults. Children tend to have a more variable involvement than the subpleural and posterior and basal topography described in adults. Interlobular thickening and air bronchogram found in adults with COVID-19 are not frequent in children. Pulmonary embolism reported in up to 30% of adults has not been yet reported in children. Original articles describing chest CT features in children with COVID-19 in the English literature are limited to small populations of Chinese children. Chest CT imaging features are very diverse across the selected studies and globally different from those reported in adults. Data from children of different countries would provide a more comprehensive description of chest CT features in children with COVID-19.

RESUMEN

COVID-19, caused by SARS-CoV-2, has resulted in a global pandemic recently. With no approved vaccination or treatment, governments around the world have issued guidance to their citizens to remain at home in efforts to control the spread of the disease. The goal of controlling the spread of the virus is to prevent strain on hospitals. In this paper, we focus on how non-invasive methods are being used to detect COVID-19 and assist healthcare workers in caring for COVID-19 patients. Early detection of COVID-19 can allow for early isolation to prevent further spread. This study outlines the advantages and disadvantages and a breakdown of the methods applied in the current state-of-the-art approaches. In addition, the paper highlights some future research directions, which need to be explored further to produce innovative technologies to control this pandemic.

RESUMEN

Tuberculosis of the skull or calvarial tuberculosis (CTB) is rare. The literature until 2019 reported less than 60 cases of CTB in childhood. The authors describe two patients with CTB associated with other manifestations of TB, such as: spine and rib injuries, peripheral adenopathy, hepatic and splenic involvement who improved with chemotherapy. The patients were a four-year-old and an eight-year-old child, whose diagnoses were confirmed by histopathological, bacteriological or molecular investigation. Both were not infected with the human immunodeficiency virus (HIV) and did not need orthopedic treatment.

RESUMEN

OBJECTIVE: To evaluate the feasibility of ultrasound in diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. MATERIAL AND METHODS: We analyzed ultrasonic findings in 216 patients with chronic inflammatory complications of colonic diverticular disease. Chronic paracolic inflammatory mass as the most common and significant chronic complication of diverticular disease was analyzed in 116 patients. Ultrasonic findings were compared with specimen assessment, intraoperative data, irrigoscopy, colonoscopy, endoscopic ultrasound and computed tomography data. RESULTS: Sensitivity of ultrasound for diagnosis of chronic paracolic inflammatory mass was 76,7%, specificity - 100%, overall accuracy - 87,5%. CT and endoscopic ultrasound were the most informative among different diagnostic tools (sensitivity 79,6% and 77,8%, respectively). CONCLUSION: Ultrasonic examination and computed tomography are the most valuable methods for diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. Ultrasound is a first-line method for diagnosis and follow-up of complicated diverticular disease due to its availability, safety and unnecessary special preparation of patients.

RESUMEN

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. The infection has been reported in most countries around the world. As of August 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. It has become apparent that although COVID-19 predominantly affects the respiratory system, many other organ systems can also be involved. Imaging plays an essential role in the diagnosis of all manifestations of the disease, as well as its related complications, and proper utilization and interpretation of imaging examinations is crucial. With the growing global COVID-19 outbreak, a comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystemic involvement, and evolution of imaging findings is essential for effective patient management and treatment. To date, only a few articles have been published that comprehensively describe the multisystemic imaging manifestations of COVID-19. The authors provide an inclusive system-by-system image-based review of this life-threatening and rapidly spreading infection. In part 1 of this article, the authors discuss general aspects of the disease, with an emphasis on virology, the pathophysiology of the virus, and clinical presentation of the disease. The key imaging features of the varied pathologic manifestations of this infection that involve the pulmonary and peripheral and central vascular systems are also described. Part 2 will focus on key imaging features of COVID-19 that involve the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as pediatric and pregnancy-related manifestations of the virus. Vascular complications pertinent to each system will be also be discussed in part 2. Online supplemental material is available for this article. ©RSNA, 2020.

RESUMEN

Rationale: Coronavirus disease 2019 (COVID-19) was first announced in Wuhan, and has rapidly evolved into a pandemic. However, the risk factors associated with the severity and mortality of COVID-19 are yet to be described in detail. Methods: We retrospectively reviewed the information of 1525 cases from the Leishenshan Hospital in Wuhan. Univariate and multivariate Cox regression analyses were generated to explore the relationship between procalcitonin (PCT) level and the progression and prognosis of COVID-19. Univariate and multivariate logistic regression analyses were performed to explore the relationship between disease severity in hospitalized patients and their PCT levels. Survival curves and the cumulative hazard function for COVID-19 progression were conducted in the two groups. To further detect the relationship between the computed tomography score and survival days, curve-fitting analyses were performed. Results: Patients in the elevated PCT group had a higher incidence of severe and critical severity conditions (P < 0.001), death, and higher computed tomography (CT) scores. There was an association between elevated PCT levels and mortality in the univariate ((hazard ratio [1], 3.377; 95% confidence interval [2], 1.012-10.344; P = 0.033) and multivariate Cox regression analysis (HR, 4.933; 95% CI, 1.170-20.788; P = 0.030). Similarly, patients with elevated PCT were more likely to have critically severe disease conditions in the univariate (odds ratio [2], 7.247; 95% CI, 3.559-14.757; P < 0.001) and multivariate logistic regression analysis (OR, 10.679; 95% CI, 4.562-25.000; P < 0.001). Kaplan-Meier curves showed poorer prognosis for patients with elevated PCT (P = 0.024). The CT score 1 for patients with elevated PCT peaked at day 40 following the onset of symptoms then decreased gradually, while their total CT score was relatively stable. Conclusion: PCT level was shown as an independent risk factor of in-hospital mortality among COVID-19 patients. Compared with inpatients with normal PCT levels, inpatients with elevated PCT levels had a higher risk for overall mortality and critically severe disease. These findings may provide guidance for improving the prognosis of patients with critically severe COVID-19.

RESUMEN

Background: During the outbreak period of COVID-19 pneumonia, cancer patients have been neglected and in greater danger. Furthermore, the differential diagnosis between COVID-19 pneumonia and radiation pneumonitis in cancer patients remains a challenge. This study determined their clinical presentations and radiological features in order to early diagnose and separate COVID-19 pneumonia from radiation pneumonitis patients promptly. Methods and Findings: From January 21, 2020 to February 18, 2020, 112 patients diagnosed with suspected COVID-19 were selected consecutively. A retrospective analysis including all patients' presenting was performed. Four patients from 112 suspected individals were selected, including 2 males and 2 females with a median age of 54 years (range 39-64 years). After repeated pharyngeal swab nucleic acid tests, 1 case was confirmed and 3 cases were excluded from COVID-19 pneumonia. Despite the comparable morphologic characteristics of lung CT imaging, the location, extent, and distribution of lung lesions between COVID-19 pneumonia and radiation pneumonitis differed significantly. Conclusions: Lung CT imaging combined with clinical and laboratory findings can facilitate early diagnosis and appropriate management of COVID-19 pneumonia with a history of malignancy and radiation therapy.

RESUMEN

We aimed to summarize reliable medical evidence by the meta-analysis of all published retrospective studies that examined data based on the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by clinical symptoms, molecular (RT-PCR) diagnosis, and characteristic CT imaging features in pregnant women. The MEDLINE, PubMed, Scopus, ISI Web of Science, ClinicalKey, and CINAHL databases were used to select the studies. Then, 384 articles were received, including the studies until 01/May/2020. As a result of the full-text evaluation, 12 retrospective articles covering all the data related were selected. A total of 181 pregnant cases with SARS-CoV-2 infections were included in the meta-analysis within the scope of these articles. According to the results, the incidence of fever was 38.1% (95% CI: 14.2-65%) and cough was 22% (95% CI: 10.8-35.2%) among all clinical features of pregnant cases with SARS-CoV-2 infection. So, fever and cough are the most common symptoms in pregnant cases with SARS-CoV-2 infection, and 91.8% (95% CI: 76.7-99.9%) of RT-PCR results are positive. Moreover, abnormal CT incidence is 97.9% (95% CI: 94.2-99.9%) positive. No case was death. However, as this virus spreads globally, it should not be overlooked that the incidence will increase in pregnant women and maybe in the risky group. RT-PCR and CT can be used together in an accurate and safe diagnosis. In conclusion, these findings will provide important guidance for current studies regarding the clinical features and correct detection of SARS-CoV-2 infection in pregnant women, as well as whether it will create emergency tables that will require the use of a viral drug.

RESUMEN

OBJECTIVES: To analyze the CT manifestations,clinical symptoms, laboratory test and the interrelationship of them with secondary invasive pulmonary aspergillosis (IPA) in hematologic patients so as to improve the diagnosis and prognosis of this disease. METHODS: A total of 37 hematologic patients suspected of IPA in a tertiary referral center were selectedfrom Jun. 2004 to Sep. 2016 and the CT characteristics, clinical manifestations, laboratory test of these patients were retrospectively analyzed. RESULTS: There were 8 patients confirmed as IPA by sputum culture or bronchoalveolar lavage fluid culture among the 37 hematologic patients.The sensitivity of CT in the diagnosis of IPA was 75.0%, the specificity was 79.3%, the positive predictive value was 42.9%, and the negative predictive value was 91.3%. Multiple patchy shadows in both lungs were the most common CT signs of suspected and confirmed patients, followed by nodules, air bronchogram, cavitary lesions, consolidation, mass shadows, halo, and crescent sign. Cough, expectoration, and fever were the most common symptoms among the suspected and confirmed patients. ß-D-glucan (G)/galactomannan antigen (GM) tests for the most patients were negative, but the number of people with elevated procalcitonin (PCT) in the confirmed patients (57.1%) was higher than that in the suspected patients (31.4%). Results of sputum culture, PCT, G/GM test, and clinical manifestations were compared between the CT lesion progression group and the absorption group, and no significant difference was observed. CONCLUSIONS: Hematologic patients are susceptible to IPA. CT features showed no obvious specificity, and the G/GM test was normal in most patients. So when hematologic patients have clinical symptoms such as cough, expectoration and fever, the possibility of combination with IPA should be considered as soon as possible, and relevant examinations such as sputum culture, bronchoalveolar lavage fluid culture and pathological examination should be completed for early diagnosis and treatment to improve the prognosis of patients.

RESUMEN

The COVID-19 diagnostic approach is mainly divided into two broad categories, a laboratory-based and chest radiography approach. The last few months have witnessed a rapid increase in the number of studies use artificial intelligence (AI) techniques to diagnose COVID-19 with chest computed tomography (CT). In this study, we review the diagnosis of COVID-19 by using chest CT toward AI. We searched ArXiv, MedRxiv, and Google Scholar using the terms "deep learning", "neural networks", "COVID-19", and "chest CT". At the time of writing (August 24, 2020), there have been nearly 100 studies and 30 studies among them were selected for this review. We categorized the studies based on the classification tasks: COVID-19/normal, COVID-19/non-COVID-19, COVID-19/non-COVID-19 pneumonia, and severity. The sensitivity, specificity, precision, accuracy, area under the curve, and F1 score results were reported as high as 100%, 100%, 99.62, 99.87%, 100%, and 99.5%, respectively. However, the presented results should be carefully compared due to the different degrees of difficulty of different classification tasks.

RESUMEN

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (ECMO) is increasingly being utilized in patients with massive pulmonary embolism (PE). However, the efficacy and the safety remain uncertain. This study aimed to investigate clinical courses and outcomes in ECMO-treated patients with acute PE. METHODS: Twenty-one patients with acute PE rescued by ECMO from January 2012 to December 2019 were retrospectively analysed. Clinical features, laboratory biomarkers, and imaging findings of these patients were reviewed, and the relationship with immediate outcome and clinical course was investigated. RESULTS: Sixteen patients (76.2%) experienced refractory circulatory collapse requiring cardiopulmonary resuscitation (CPR) or ECMO support within 2 h after the onset of cardiogenic shock, and none could receive definitive reperfusion therapy before ECMO initiation. Before or during ECMO support, more than 90% of patients had imaging signs of right ventricular (RV) dysfunction. In normotension patients, the computed tomography (CT) value was a valuable predictor of rapid disease progression compared with cardiac troponin I level. Ultimately, in-hospital death occurred in ten patients (47.6%) and 90% of them died of prolonged CPR-related brain death. Cardiac arrest was a significant predictor of poor prognosis (p = 0.001). CONCLUSIONS: ECMO appears to be a safe and effective circulatory support in patients with massive PE. Close monitoring in intensive care unit is recommended in patients with RV dysfunction and aggressive use of ECMO may reduce the risk of sudden cardiac arrest and improve clinical outcome.

RESUMEN

BACKGROUND: Aortoesophageal fistula (AEF) caused by an esophageal foreign body is a life-threatening crisis, with rapid progress and high mortality. The first case of AEF was reported in 1818, but the first successfully managed case was not until 1980. Although there have been some reports on this condition, in most cases, the aorta was invaded and corroded due to its adjacent relationship with the esophagus and subsequent mediastinitis. To date, few reports have described an aortic wall directly penetrated by a sharp foreign body, likely because this type of injury is extremely rare and most patients cannot receive timely treatment. Here, we present a rare case of a fish bone that directly pierced the aorta via the esophagus. CASE PRESENTATION: A 31-year-old female experienced poststernum swallowing pain after eating a meal of fish. Gastroscope showed a fishbone-like foreign body had penetrated the esophagus wall. Computed tomography revealed that the foreign body had directly pierced the aorta to form an AEF. Surgery was successfully performed to repair the aorta and esophagus. The postoperation and follow-up was uneventful. CONCLUSIONS: For the treatment of foreign bodies in the esophagus, we should be alert of the possibility of AEFs. The effective management of AEFs requires early diagnosis and intervention, as well as long-term treatment and follow-up, which still has a long way to go.

RESUMEN

AIMS AND OBJECTIVES: Early detection of rheumatoid injury in the temporomandibular joint using CT, which accurately detects bone changes before the clinical symptoms start appearing to protect the joint from irreversible damage, and the correlation of those radiological changes with the duration of rheumatoid arthritis disease. MATERIALS AND METHODS: It included 45 people aged 27-74 years who reviewed the internal medicine and rheumatology clinics at Al-Mouwasat Hospital during 2016-2018 and are affected with rheumatoid arthritis according to the criteria American College of Arthritis (ACR) European League against Rheumatism (EULAR) 2010 criteria. The informed consent of the patient and the approval of the Scientific Research Council were obtained to conduct the research. RESULTS: Computed tomography revealed the radiological changes in the left and right side, respectively, in terms of p value <0.05: (1) Erosion of condyle (42.22-53.34%). (2) Decreased in the joint space (53.33-60.00%). (3) Mandibular subchondral cysts in both sides (77.14%). (4) Erosion of the articular fossa (48.89-57.78%). (5) Flattening of condyle (46.67-55.55%). (6) Effusion (2.22-4.44%). (7) Bone marrow edema (26.67-40.00%). (8) Subchondral sclerosis (60.00-73.33%). Conclusion and clinical significance: The occurrence of bone damage in the condyle and articular fossa of the temporomandibular joint despite the fact that the sample members have no clinical complaint indicates the ability of CT scan of early and accurate disclosure of rheumatoid injury in the temporomandibular joint.
