Spontaneous Intracranial Hypotension Complicated by a Cerebral Venous Thrombosis Following an mRNA Covid-19 Vaccination: Coincidence vs Cause?

Unlabelled: Spontaneous intracranial hypotension (SIH) is a rare cause of persistent headache, particularly among young and middle-aged people. A potentially life-threatening complication of SIH is a cerebral venous thrombosis (CVT). The authors present a case in which a patient presented with SIH complicated by CVT one week after receiving a booster dose of mRNA COVID-19 vaccine.

A reversible and efficient probe for dual mode recognition of Al and Cu with logic gate behaviour: Crystal structure, theoretical and in-vivo bio-imaging investigations.

This work presents the synthesis, characterization, crystal structure and spectroscopic investigations of isophthalohydrazide based probe. Among various tested metal ions, the probe selectively detects Al and Cu in aqueous ethanol via fluorometric and colorimetric methods, respectively. It displays a fluorescence "turn-on" response with Al and visual colour change from colourless to yellow with Cu.

Cerebral Venous Thrombosis and Acute Pulmonary Embolism following Varicella Infection.

Unlabelled: Varicella infection is caused by varicella-zoster virus (VZV) and commonly presents as a self-limiting skin manifestation in children. VZV also causes cerebral arterial vasculopathy and antibody-mediated hypercoagulable states leading to thrombotic complications in children, although there are very few such reports in adults. Postulated causal factors include vasculitis, direct endothelial damage, or acquired protein S deficiency secondary to molecular mimicry.

FT-IR spectroscopy, intra-molecular C-H⋯O interactions, HOMO, LUMO, MESP analysis and biological activity of two natural products, triclisine and rufescine: DFT and QTAIM approaches.

The present study deals with two natural products, triclisine and rufescine which are extracted from the Amazonian wines but ubiquitous in nature. The quantum chemical density functional method at B3PW91/6-311+G(d,p) level is used to obtain the equilibrium geometries of these molecules. The quantum theory of atoms-in-molecule approach is employed to study various intra-molecular C-H⋯O interactions within these molecules.

Role of whole-body magnetic resonance imaging in the evaluation of extrapulmonary tuberculosis in immunocompetent patients.

Objective: The aim of this study was to evaluate the role of whole-body magnetic resonance imaging (WB-MRI) in imaging of extrapulmonary tuberculosis.

Methods: Eighteen patients with single-site extrapulmonary tuberculosis were evaluated with contrast-enhanced dedicated MRI of the clinically symptomatic site followed by WB-MRI using contrast-enhanced 3-dimensional (3D) modified DIXON technique (m-DIXON) and diffusion-weighted WB imaging with background body signal suppression (DWIBS) sequences. Studies were read by 2 experienced radiologists, and additional lesions seen on WB-MRI were separately charted.

Significance of various pulmonary and extrapulmonary abnormalities on HRCT of the chest in scleroderma lung.

Patients with systemic sclerosis (SSc) are routinely investigated with high-resolution computed tomography (HRCT) chest for early detection and accurate characterization of complicating interstitial lung diseases. Though the primary aim of HRCT is to delineate the burden of pulmonary involvement and to characterize the nature of fibrosis to potentially help guide management, it provides an opportunity to evaluate extrapulmonary manifestations, particularly the dilated pulmonary artery, esophageal dilatation, and pericardial abnormalities which have their own clinical significance. The aim of this article is to discuss the significance of various pulmonary and extrapulmonary abnormalities that may be identified on HRCT chest of SSc patients.

Oesophageal dilatation on high-resolution CT chest in systemic sclerosis: what does it signify?

Objective: To evaluate the significance of oesophageal dilatation on high-resolution CT (HRCT) chest in patients with systemic sclerosis.

Methods: We retrospectively retrieved the database of patients with systemic sclerosis seen at our hospital between January 2008 and January 2009. A total of 50 patients (46 women and four men) who had HRCT chest, pulmonary function testing and echocardiography within 1 month were included in the study.

Predictors of pulmonary hypertension on high-resolution computed tomography of the chest in systemic sclerosis: a retrospective analysis.

Purpose: To evaluate the imaging features on high-resolution computed tomography (HRCT) of the chest and the clinical parameters that are associated with pulmonary hypertension in systemic sclerosis. We specifically investigated whether main pulmonary artery (MPA) diameter and burden of lung fibrosis are predictors of pulmonary hypertension in these patients.

Methods: We retrospectively retrieved the database information of patients with systemic sclerosis seen at our hospital between January 2007 and December 2008.

Case Report: Anteromedial temporosphenoidal encephalocele with a clinically silent lateral bony defect in the greater wing of the sphenoid.

Anteromedial temporosphenoidal encephalocele is the least common type of temporal encephalocele. It commonly presents with spontaneous cerebrospinal fluid rhinorrhea in adults. This article presents the CT cisternography and MRI findings of one such case, which also had an associated clinically silent defect in the greater wing of the sphenoid on the same side.
