RESUMEN
IgG4-related disease (IgG4-RD) is a rare and often misdiagnosed disorder with limited literature that highlights the different neurological presentations of this treatable disease. The diagnosis of IgG4-RD could be challenging, while imaging is fundamental for the diagnosis, biopsy is considered the gold standard. Most cases respond well to steroids and immunosuppressive therapy. This is a case series study that illustrates the varied neurological presentations of IgG4-RD through three different patients that were followed at the Montreal Neurological Institute. This paper takes you through the diagnostic strategy that we followed to accurately diagnose and treat those patients.
RESUMEN
BACKGROUND: Nausea and vomiting in pregnancy often require pharmacotherapy for symptom management. Serotonin syndrome is a rare clinical entity that can be precipitated by the medications used to treat nausea and vomiting in pregnancy. CASE: A 35-year-old pregnant individual with a history of hyperemesis gravidarum in an earlier pregnancy requiring prolonged hospitalization presented with nausea and vomiting at 7 weeks of gestation. She was incidentally found to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection when she was universally screened at the time of admission. She required pharmacotherapy, including prochlorperazine and ondansetron for treatment of nausea as well as sumatriptan for migraine. She developed acute spasticity, autonomic dysfunction, and temperature rise, precipitated by antiemetic therapy, consistent with serotonin syndrome. The syndrome resolved with supportive care and benzodiazepines. CONCLUSION: Serotonin syndrome is a serious clinical entity that can be provoked by the pharmacotherapy given to treat nausea and vomiting in pregnancy. This medical emergency requires early recognition and prompt management.

BACKGROUND AND PURPOSE: Cellular adhesion molecules may play a critical role in the inflammatory process leading to atherosclerosis. The purpose of this study was to determine whether soluble intercellular adhesion molecule-1 (sICAM-1) is a predictor of future ischemic events in high-risk individuals and also whether it is associated with carotid artery stenosis. METHODS: We conducted a prospective study of sICAM-1 concentration in 3 groups: (1) subjects with recent (< 7 days) ischemic stroke or TIA, (2) asymptomatic subjects with carotid stenosis > or = 50% and (3) asymptomatic individuals with vascular risk factors. Subjects were followed for a minimum of 3 years. sICAM-1 levels were compared between the groups and correlated with the risk of ischemic events and the degree of carotid artery stenosis. RESULTS: We studied 275 subjects. Mean sICAM-1 levels were significantly higher in those with recent ischemic stroke or TIA compared to those with risk factors alone. During follow-up, ischemic events occurred almost nine times more frequently in subjects in group 1 compared to group 3. sICAM-1 concentration was not predictive of future ischemic events (OR 1.001, 95% CI 0.998-1.004). There was no significant association between sICAM-1 concentration and carotid artery stenosis (OR 1.001, 95% CI 0.999-1.004). CONCLUSIONS: Mean sICAM-1 levels were higher in subjects with recent cerebral ischemia. No association between sICAM-1 and carotid artery stenosis was observed. Neither baseline nor subsequent sICAM-1 levels were predictive of the risk of future ischemic events.

OBJECTIVES: To estimate the extent of activity and participation of individuals 6 months poststroke and their influence on health-related quality of life (QOL) and overall QOL, information that would be useful in identifying services that stroke patients would need in the community. DESIGN: Inception cohort study. SETTING: Ten acute care hospitals in metropolitan areas of the province of Quebec. PARTICIPANTS: Persons with first-ever stroke, either ischemic or hemorrhagic. In parallel, a population-based sample of community-dwelling individuals without stroke, frequency matched in age and city district, were also recruited. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Stroke subjects were interviewed by telephone at 6-month intervals for 2 years of follow-up. The community-dwelling individuals without stroke were also followed. RESULTS: A total of 434 persons were interviewed approximately 6 months poststroke. Their average age +/- standard deviation was 68.4+/-12.5 years; the average age of the 486 controls was 61.7+/-12.4 years. The stroke group scored on average 90.6/100 on the Barthel Index; 39% reported a limitation in functional activities, 54% reported limitations with higher-level activities of daily living such as housework and shopping, and 65% reported restrictions in reintegration into community activities. By using the Medical Outcomes 36-Item Short-Form Health Survey (SF-36), persons with stroke rated their physical health 7 points lower than healthy peers; also, 7 of the 8 subscales of the SF-36 were affected by stroke. CONCLUSION: Almost 50% of the community-dwelling stroke population lived with sequelae of stroke such that, unless there was a full-time and able-bodied caregiver at home, they needed some form of home help. A large proportion also reported lack of meaningful activity, indicating a need for organized support groups for people with stroke; otherwise, boredom will lead to depression and worsening of function, affect, health status, and QOL.
