“…X-ray findings may be normal in early disease and tend to appear about 10-12 days after onset of symptoms and normal CXR were seen in 31% of patients in study performed by Wong et al 1 , 7 In our study, only 2.8% patients had normal X-ray at presentation. However, majority of the patients presented with advance disease and an abnormal X-ray on admission.The common findings in COVID-19 on CT include ground glass opacities with or without reticulation and consolidations mostly bilateral, peripheral and involving lower lung fields.…”

“…Imaging findings in COVID-19 are most commonly of atypical organizing pneumonia, often with bilateral, peripheral and basal predominant distribution. 7 Different patterns observed in the study were ground glass haze in the early phase with increasing density as the disease progresses. Next stage is the development of heterogeneous dense lobar consolidation becoming homogenous and multi lobar as the disease progresses.…”

“…In the COVID 19 pandemic mobile X-ray unit is the preferred imaging modality used worldwide due to ease of decontamination and most suitable for critically ill patients on support. 5 - 7 Serial X-rays were performed on patients who had longer duration of hospital stay. X-ray findings were evaluated in terms of the pattern, distribution, unilateral or bilateral disease and the number of zones involved.…”

Objective: To determine the pattern of COVID-19 on chest radiograph in patients presenting to Lady Reading Hospital, Peshawar, Pakistan. Methods: This prospective observational study was conducted on 178 consecutive swab positive COVID-19 patients presenting to Lady Reading Hospital, Peshawar, Pakistan from 15th March to 15th June 2020. Patients of all ages and both genders were included. Chest X-rays performed by portable radiography unit were viewed for different patterns by two consultant radiologists independently and results were analyzed using IBM SPSS 20. Results: Out of 178 patients 134 were male. Mean age was 55.67 years. Radiographic patterns observed were ground glass haze without or with reticulation and/or consolidation (45.5 % and 33.2% respectively) and predominant consolidation either alone or in combination with ground glass haze or other findings (27.1% collectively). Peripheral distribution pattern was seen in 69.1% of patients with bilateral findings in 84.3%. Further categorization was based on pulmonary zonal demarcation with changes most commonly involving four zones (33.1%) i.e., the lower and mid zones bilaterally. Conclusion: Portable chest radiography is an essential supporting tool for assessing different patterns in COVID-19 infection. The most common pattern observed is alveolar opacities with predominant peripheral distribution either unilateral or more frequently bilateral, starting from the lower and mid zones extending to the upper zones and becoming diffuse with disease progression. doi: https://doi.org/10.12669/pjms.37.1.3435 How to cite this:Nishtar T, Noor N, Khan SL.

“…Les signes radiologiques les plus observées sont les opacités en verre dépoli et les condensations parenchymateuses [ 6 , 20 ]. Comme pour les signes cliniques et les anomalies biologiques, la fréquence des signes radiologiques suggestives de COVID-19 est variable d´une étude à une autre [ 6 , 21 ]. Selon l’OMS, près de 190000 personnes pourraient mourir du COVID-19 en Afrique si la pathologie n’est pas maîtrisée [ 22 ].…”

Introduction Aucune étude antérieure n’a élaboré le profil des patients Algériens hospitalisés pour COVID-19. L’objectif de cette étude était de déterminer le profil clinique, biologique et tomodensitométrique des patients Algériens hospitalisés pour COVID-19. Méthodes Une étude prospective était menée auprès des patients hospitalisés pour COVID-19 (période: 19 mars-30 avril 2020). Les données cliniques, biologiques et radiologiques, le type de traitement reçu et la durée de l’hospitalisation étaient notés. Résultats Le profil clinique des 86 patients atteints de COVID-19 était un homme non-fumeur, âgé de 53 ans, qui était dans 42% des cas en contact avec un cas suspect/confirmé de COVID-19 et ayant une comorbidité dans 70% des cas (hypertension artérielle, diabète sucré, pathologie respiratoire chronique et allergie, cardiopathie). Les plaintes cliniques étaient dominées par la triade «asthénie-fièvre-toux» dans plus de 70% des cas. Les anomalies biologiques les plus fréquentes étaient: syndrome inflammatoire biologique (90,1%), basocytémie (70,8%), lymphopénie (53,3%), augmentation de la lactico-deshydrogénase (52,2%), anémie (38,7%), augmentation de la phosphokinase (28,8%) et cytolyse hépatique (27,6%). Les signes tomodensitométriques les plus fréquents étaient: verre dépoli (91,8%), condensations alvéolaires (61,2%), verre dépoli en plage (60,0%), et verre dépoli nodulaire (55,3%). Un traitement à base de «chloroquine, azithromycine, zinc, vitamine C, enoxaparine, double antibiothérapie et ± corticoïdes» était prescrit chez 34,9% des patients. La moyenne de la durée d’hospitalisation était de 7±3 jours. Conclusion La connaissance des profils des formes modérées et sévères du COVID-19 contribuerait à faire progresser les stratégies de contrôle de l’infection en Algérie.

“…The diagnosis of COVID-19 was defined as a positive reverse transcription polymerase chain reaction (RT-PCR) test for SARS-CoV-2 on a nasopharyngeal swab. Patients with negative virus detection by RT-PCR (18/265; 6.8%) but a high clinical suspicion of disease were also diagnosed with COVID-19 [ 11 ].…”

Background Stroke in the course of coronavirus disease (COVID-19) has been shown to be associated with more severe respiratory symptoms and higher mortality, but little knowledge in this regard exists on older populations. We aimed to investigate the incidence, characteristics, and prognosis of acute stroke in geriatric patients hospitalized with COVID-19. Methods A monocentric cross-sectional retrospective study of 265 older patients hospitalized with COVID-19 on acute geriatric wards. 11/265 presented a stroke episode during hospitalization. Mortality rates and two-group comparisons (stroke vs non-stroke patients) were calculated and significant variables added in logistic regression models to investigate stroke risk factors. Results Combined ischemic and hemorrhagic stroke incidence was 4.15%. 72.7% of events occurred during acute care. Strokes presented with altered state of consciousness and/or delirium in 81.8%, followed by a focal neurological deficit in 45.5%. Ischemic stroke was more frequently unilateral (88.8%) and localized in the middle cerebral artery territory (55.5%). Smoking and a history of previous stroke increased by more than seven (OR 7.44; 95% CI 1.75–31.64; p = 0.007) and five times (OR 5.19; 95% CI 1.50–17.92; p = 0.009), respectively, the risk of stroke. Each additional point in body mass index (BMI) reduced the risk of stroke by 14% (OR 0.86; 95% CI 0.74–0.98; p = 0.03). In-hospital mortality (32.1% vs. 27.3%; p > 0.999) and institutionalization at discharge (36.4% vs. 21.1%; p = 0.258) were similar between patients with and without stroke. Conclusion Incident stroke complicating COVID-19 in old patients was associated with active smoking, previous history of stroke, and low BMI. Acute stroke did not influence early mortality or institutionalization rate at discharge.
