Background: Alterations in the cerebral venous system have been increasingly recognized as a significant component of the pathophysiology of multiple sclerosis (MS). This study aimed to explore the relationship between venous sinus diameter and MS to understand potential vascular alterations in MS patients compared with controls. We sought to determine whether these alterations were correlated with disease characteristics such as duration, lesion type, and disability score.
Methods: This study included 79 MS patients diagnosed according to the 2017 McDonald criteria and 67 healthy individuals. Magnetic resonance imaging (MRI) scans via a 1.5 Tesla system provided measurements of the superior sagittal sinus, right and left transverse sinus, sinus rectus, and venous structures. Statistical analysis was conducted via SPSS, employing independent sample t tests, ANOVA, chi-square tests, and Pearson correlation analysis, with the significance level set at < 0.05.
Results: This study revealed significant differences in venous sinus diameter between MS patients and controls, with MS patients exhibiting larger diameters. Specifically, patients with brainstem and spinal lesions had larger diameters in certain sinus regions. No significant correlations were found between venous sinus diameter and demographic factors, expanded disability status scale scores, or lesion counts. However, a significant increase in perivenular lesions was noted in patients with longer disease durations.
Conclusions: The findings indicate notable vascular alterations in MS patients, particularly in venous sinus diameters, suggesting a potential vascular component in MS pathology. The lack of correlation with conventional clinical and MRI metrics highlights the complexity of MS pathology. These insights underscore the need for further research, particularly longitudinal studies, to elucidate the role of venous changes in MS progression and their potential as therapeutic targets.

Outcomes of venous sinus stenosis stenting in patients with pulsatile tinnitus and sigmoid sinus wall anomalies.

Background: Transverse sinus stenosis (TSS) and sigmoid sinus wall anomalies (SSWAs) are the most common causes of pulsatile tinnitus (PT). While these conditions may co-occur, they usually require different management approaches. This study aims to evaluate whether TSS stenting alone, without targeted treatment of SSWAs, is sufficient to resolve PT in patients presenting with PT, TSS, and SSWAs.

Background: Dural arteriovenous fistulas (DAVFs) are abnormal communications between dural arteries and cortical, meningeal, or dural sinus veins. They represent 10-15% of intracranial arteriovenous malformations. In rare cases, they have been associated with potentially reversible cognitive impairment and dementia.

Skeletal muscle relaxants have their place in everyday use in numerous anesthesiological procedures, such as preparing a patient for surgery, supporting mechanical ventilation, and performing effective intubation. These drugs can be divided, based on their mechanism of action, into depolarizing skeletal relaxants, such as succinylcholine, and non-depolarizing skeletal muscle relaxants. Non-depolarizing agents are further categorized, based on their structure, into steroidal (eg, rocuronium) and benzylisoquinoline (eg, atracurium) compounds.

Article Synopsis
- This study examines a rare complication of cerebral venous thrombosis (CVT) in patients with primary Sjögren's syndrome (pSS), discussing clinical features, treatment, and outcomes.
- A total of twelve patients were reviewed, predominantly middle-aged women, with common symptoms including headache and typical pSS manifestations such as dry mouth and arthritis.
- All patients received treatment including anticoagulants and recovered fully, highlighting the need for increased awareness and screening for autoimmune diseases in CVT cases, especially with unilateral transverse sinus involvement.

Many dietary supplements commonly used by bodybuilders and athletes carry thrombogenic risks, potentially leading to life-threatening conditions like arterial and venous thrombosis by either elevating testosterone levels or directly interfering with homeostasis. Increased awareness and further research are crucial for consumer safety and supplement regulation.
