Refractory chronic spontaneous urticaria after heterologous COVID-19 booster vaccination.

Chronic spontaneous urticaria (CSU) involves recurrent, pruritic wheals lasting more than 6 weeks in response to various etiologies, including unknown causality. Though most cutaneous reactions to the COVID-19 vaccine series are self-limited and of short duration, more complex presentations including chronic spontaneous urticaria have been described. To the best of our knowledge, this is the first report of chronic spontaneous urticaria following heterologous mRNA COVID-19 booster vaccination that includes vaccination with both forms of the mRNA vaccine. Our patient received Pfizer-BioNTech for the primary series and Moderna for the booster. After failing several therapies, our patient's urticaria was refractory even to omalizumab. The source for chronic spontaneous urticaria development in our patient may be related to the unique humoral response elicited by receipt of a different mRNA vaccine manufacturer.

Exploring the presence of multiple abnormal non-motor features in patients with cervical dystonia.

This study's aim was to investigate prevalence of four non-motor symptoms in patients with cervical dystonia and healthy controls to explore whether the presence of multiple non-motor features is associated with cervical dystonia diagnosis. Fifteen patients with cervical dystonia and 15 healthy controls underwent non-invasive testing of spatial discrimination threshold, temporal discrimination threshold, vibration-induced illusion of movement, and kinesthesia. All spatial discrimination threshold, temporal discrimination threshold, and vibration-induced illusion of movement measures were converted to standardized Z scores with scores >2.0 considered abnormal. Any incorrect kinesthesia response was considered abnormal. Prevalence of each abnormal non-motor feature was compared between groups using a chi-squared test. A higher proportion of patients with cervical dystonia had abnormal spatial discrimination threshold (p = 0.01) and abnormal kinesthesia (p = 0.03) scores compared to healthy control subjects. There were no significant differences between the proportion of patients with cervical dystonia versus healthy controls for abnormal temporal discrimination threshold (p = 0.07) or abnormal vibration-induced illusion of movement (p = 0.14). Forty-seven percent of patients with cervical dystonia (7/15) demonstrated one abnormal non-motor feature, 20% (3/15) displayed two abnormal features, and 13% (2/15) displayed three abnormal features. Kinesthesia was the only non-motor feature identified as abnormal in the control group (20%, 3/15). All four tests demonstrated high specificity (80-100%) and low-moderate sensitivity (13-60%). These findings suggest that non-motor feature testing, specifically for spatial discrimination threshold and kinesthesia, could be a highly specific diagnostic tool to inform cervical dystonia diagnosis. Further investigation is needed to confirm these findings.

The Minimum Data Set: An Opportunity to Improve Spasticity Screening.

Spasticity is a common movement disorder that arises from trauma or disease affecting the central nervous system. Untreated spasticity can result in limitations in completing activities of daily living, painful limb contractures, and other conditions associated with loss of mobility. In the long-term care setting, this treatable condition is prevalent, yet often unrecognized likely because of a lack of spasticity-trained practitioners. A recently published spasticity referral tool holds promise for addressing the underdiagnosis of spasticity in the long-term care population. The Minimum Data Set (MDS) would be an ideal mechanism for increasing the diagnosis and treatment of spasticity because it is a government-directed comprehensive screening tool that informs care plans for all residents residing in federally funded long-term care facilities. The MDS could easily integrate the published referral assessment to record the presence of spastic postures and muscle rigidity. We propose expanding the MDS to include 3 questions related to spasticity to improve the recognition and treatment of this prevalent and treatable condition.

Prevalence of Comorbid Spasticity and Urinary Incontinence in Residents of a Long-Term Care Facility.

The current study evaluated the prevalence of comorbid spasticity and urinary incontinence (UI) in a long-term care facility. Medical history, presence of UI, and activities of daily living (ADL) dependency were obtained from medical records and Minimum Data Set 3.0. Quality of life was assessed with the EuroQoL-5D-5L (EQ-5D). Comorbid spasticity and UI presented in 29% of participants (14 of 49). Participants with spasticity and UI had higher ADL dependency and lower EQ-5D than participants without both conditions (4.9, 95% confidence interval [CI] [1.6, 80.], p = 0.003; -0.17, 95% CI [-0.33, 0.00], p = 0.044; respectively). More than one half of participants with lower limb spasticity had severe UI, compared to only 10% without lower limb spasticity (relative risk = 5.5; 95% CI [1.9, 15.9]; p = 0.006). Comorbid spasticity and UI may be common in the long-term care setting and negatively associated with ADL and quality of life. Further investigation is needed to confirm these findings.
