Management of giant-cell arteritis in Switzerland: an online national survey
CONCLUSIONS: This survey indicates that imaging and temporal biopsy are rapidly accessible for diagnosing giant-cell arteritis in Switzerland but highlights heterogeneous practice in many disease management areas.PMID:37011593 | DOI:10.57187/smw.2023.40051

Clinical and Imaging Evaluation of COVID-19-Related Olfactory Dysfunction
CONCLUSION: The average olfactory bulb volumes were significantly higher in the patients' group compared to the control group, indicating significant edema and swelling in the olfactory bulb in patients with COVID-related olfactory dysfunction. Furthermore, in most patients, no sinonasal symptoms such as nasal congestion or rhinorrhea were reported, and similarly, no radiological evidence of sinusitis was detected. Consequently, the most probable mechanism of COVID-related olfactory dysfunction is sensorineural loss through virus spread and damage to the olfactory epithelium and pathways.PMID:36945746 | DOI:10.1177/19458924231163969

Comprehensive management of paranasal sinus fungus balls: A Young ‐IFOS consensus statement
ConclusionUntil further data are available, these points provide a framework for the management of PSFB. Moreover, PSFB should be considered a noninvasive mycosis that is not necessarily symptomatic or related to odontogenic conditions. Although diagnosis may be incidental, endoscopy and single imaging (computed tomography or magnetic resonance imaging, with distinctive features) are required for diagnosis, whereas contrast medium would allow for differential diagnosis. Although treatment of PSFB should be considered mandatory before sinus augmentation and is recommended for symptomatic patients, immunosuppressed patients,...

Systematic MRI in Persistent Post Covid ‐19 Olfactory Dysfunction should be Reassessed

What Are Causes of Childhood Interstital Lung Disease?
Discussion Interstitial lung disease in children (chILD) is less understood than adult interstitial lung disease (ILD) and is rare. Prevalence is ~ 0.13 to 16.2 per 100,000 children under age 17 years. chILD is an general term for respiratory disorders that are heterogeneous, chronic and impair lung function. While some define diffuse parenchymal lung disease (DPLD) separately, the term ILD usually encompases DPLD. chILD has variable definitions and is “usually diagnosed if three of the following features are present: 1) respiratory symptoms (cough, rapid and/or difficult breathing, and exercise intolerance), 2) res...

Magnetic Resonance Imaging as a Diagnostic and Research Tool in Patients with Olfactory Dysfunction: A Systematic Review
CONCLUSION: MRI uncommonly detects intracranial pathology in patients with idiopathic OD. Among patients with mixed OD etiologies, reduced olfactory bulb and gray matter volume are the most common abnormal findings on MRI. Further research is required to better understand the role of MRI and its cost-effectiveness in patients with acquired, idiopathic OD.PMID:35585698 | DOI:10.1177/19458924221096913

Noticable Findings in Cranial MRI of the Patients with Idiopathic Intracranial Hypertension
CONCLUSION: OND/ONSD ratio is different in anterior and posterior measurements. So we recommend measuring OND and ONSD separately in IIH patients to use in the clinical practice. Similarly, optic chiasm-pituitary gland distance is also another point to note for IIH patients on MRI. Our paper adds new approach to IIH in terms of OND/ONSD ratio.PMID:35234081 | DOI:10.1177/19458924211069213

Gadopentetate meglumine activates mast cells to cause IgE-independent allergic reactions both in vitro and in vivo
In this study, the effects of Gd-DTPA in causing allergic like reactions and mast cells (MCs) activation were investigated both in vitro and in vivo. Gd-DTPA induced a severe hand paw swelling and body temperature decrease in murine topical cutaneous allergy model, and murine systemic allergy model. Meanwhile, serum IgE was not significantly changed. Histamine, tryptase, and cytokines release in mice serum and LAD2 cells supernatant were increased significantly both in mice serum and LAD2 supernatant after treated with Gd-DTPA. Subsequently, the changes in mRNA levels after Gd-DTPA activated MCs were analyzed by RNAseq and...

Heart Involvement in Systemic Sclerosis: the Role of Magnetic Resonance Imaging
AbstractSystemic sclerosis (SSc) is a severe connective tissue disease characterized by diffuse vascular damage and aberrant activation of immune system, resulting in inflammation and fibrosis of skin and internal organs, including the heart. Cardiac involvement is frequent in SSc, even though often unrecognized due to the occult nature at early stages and to the lack of a defined diagnostic algorithm. Once clinically evident, heart involvement is associated with a poor prognosis, representing the leading cause of death in about one third of SSc patients. Thus, its early recognition and monitoring are of crucial importance...

Deep learning classification of inverted papilloma malignant transformation using 3D convolutional neural networks and magnetic resonance imaging
ConclusionsA deep learning approach with 3-dimensional CNNs can distinguish IP and IP-SCC with moderate test classification performance. Although CNNs demonstrate promise to enhance the prediction of IP-SCC using MRIs, more data is needed before they can reach the predictive value already established by human MRI evaluation.This article is protected by copyright.

Evaluation of bronchial wall thickness in asthma using magnetic resonance imaging
Conclusions We have demonstrated that MRI-UTE is an accurate and reliable radiation-free method to assess bronchial wall dimensions in asthma, with enough spatial resolution to differentiate severe from non-severe asthma.
