Rhino-Orbito-Cerebral Mucormycosis During the Second Wave of Covid-19: The Indian Scenario

Application of Dynamic Contrast-Enhanced MRI in the Diagnosis of Rheumatoid Arthritis

In order to solve the application problem of dynamic contrast-enhanced MRI in the diagnosis of rheumatoid arthritis, this paper proposes application research based on dynamic contrast-enhanced MRI in the staging diagnosis of rheumatoid arthritis. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has a high value in evaluating the activity of patients with early rheumatoid arthritis (RA). This paper discusses the correlation between hemodynamic parameters and omeractramris score, clinical laboratory indexes, and activity score (DAS28), analyzes its feasibility in evaluating the prognosis of RA, and provides a reliable basis for the rational formulation of an early RA treatment plan. After reviewing the previous cases, 33 patients with subclinical synovitis of RA were selected for wrist joint contrast-enhanced ultrasonography. The data were analyzed by contrast-enhanced software, and the quantitative parameters of contrast-enhanced were obtained: start development time (AT), peak time (TTP), peak intensity (PI), grad gradient, and area under the curve (AUC). The synovial blood supply was classified by CEUS, and the CEUS blood supply classification and power Doppler (PDUS) blood supply classification were compared. The results of regression analysis showed that AUC (or = 1.026, 95% CI: 1.001–1.052) and PI (or = 1.561, 95% CI: 1.019–2.393) were independent risk factors for predicting the aggravation of the disease. The diagnostic efficacy of AUC and PI in predicting the aggravation of the disease was analyzed. The areas under the ROC curve of AUC and PI were 0.935 and 0.927, respectively, and the difference between them was not statistically significant.

Post-Covid-19 Rhino-Cerebral Mucormycosis: an Observational Study During the Second Wave

Mucormycosis is one of the most lethal and rapidly spreading fungal infection which is caused by fungus of the order Mucorales. The swiftness of spreading and high mortality rate that characterize mucormycosis cases added more burden to the enormous challenge brought by the Covid-19 pandemic globally. The aim of this article is to identify and discuss mucormycosis and review the literature related to its diagnosis and management. A total of 15 mucormycosis cases with a history of Covid-19 infection were identified in the Department of Dentistry of Shri B M Patil Medical College Hospital and Research Centre BLDE (Deemed to be University), Vijayapura, India. The duration of the study was between April 1st and mid-September 2021. Nasal swab and tissue samples from oral and maxillofacial region were collected. Blood investigations, RT-PCR and HbA1c tests and radiography revealed changes in the trabecular pattern and bone loss associated with periodontal inflammation. Mucormycosis is a life-threatening infection. Hence, dental and other clinical professionals must be aware of this possible fatal complication, so as to avoid an unfavorable outcome in clinical practice.
