ABSTRACT

The American Academy of Neurology's (AAN) 2017 Gender Disparity Report identified improving mentorship as a key intervention to fill the leadership and pay gaps for women in neurology. Here we summarize the literature on mentoring women, provide an outline of ideal components of programs geared toward closing gender gaps, and present a mentoring program for AAN members. The strategies discussed share similarities with those for closing gaps related to race, ethnicity, and religion. Developing effective mentorship and sponsorship programs is essential to ensure a sufficiently diverse pool of academic faculty and private practitioners and to establish equal representation in leadership roles in this field.

ABSTRACT

PURPOSE OF REVIEW: Pediatric central nervous system demyelinating diseases include multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and acute disseminated encephalomyelitis (ADEM). As diagnostic criteria become more inclusive, the risk of misdiagnosis of atypical demyelinating diseases of rheumatologic, infectious, and autoimmune etiology increases. RECENT FINDINGS: We review mimics of multiple sclerosis, neuromyelitis optica spectrum disorder, and acute disseminated encephalomyelitis, including rheumatologic diseases: systemic lupus erythematosus and neuro-Behçet disease; infectious diseases: human immunodeficiency virus, progressive multifocal leukoencephalopathy, and subacute sclerosis panencephalitis; and autoimmune diseases including X-linked Charcot-Marie-Tooth disease, chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) and autoimmune glial fibrillary acidic protein (GFAP) encephalopathy. Atypical demyelinating disease may mimic classic neuroinflammatory diseases of the central nervous system. Imaging may meet criteria for a diagnosis of multiple sclerosis, or patients may present with optic neuritis and transverse myelitis consistent with neuromyelitis optica spectrum or myelin oligodendrocyte glycoprotein (MOG) antibody disorders. Through careful history-taking and review of atypical MRI findings, we may avoid misdiagnosis and mistreatment.

ABSTRACT

We report an 18-month-old infant with ischemic stroke, neurocognitive impairment, and psychomotor retardation in the setting of severe iron deficiency anemia. Although an uncommon outcome in anemic children, stroke is important to consider as a cause for developmental delay in children with iron deficiency anemia.

ABSTRACT

In recent years, several studies have examined the potential associations between mitochondrial dysfunction and neurodegenerative diseases such as multiple sclerosis (MS), Parkinson's disease and Alzheimer's disease. In MS, neurological disability results from inflammation, demyelination, and ultimately, axonal damage within the central nervous system. The sustained inflammatory phase of the disease leads to ion channel changes and chronic oxidative stress. Several independent investigations have demonstrated mitochondrial respiratory chain deficiency in MS, as well as abnormalities in mitochondrial transport. These processes create an energy imbalance and contribute to a parallel process of progressive neurodegeneration and irreversible disability. The potential roles of mitochondria in neurodegeneration are reviewed. An overview of mitochondrial diseases that may overlap with MS are also discussed, as well as possible therapeutic targets for the treatment of MS and other neurodegenerative conditions.

ABSTRACT

Myelin oligodendrocyte glycoprotein is expressed in the central nervous system on the surface of oligodendrocytes and is associated with a broad range of adult and pediatric demyelinating phenotypes. The entire spectrum of clinical and radiologic features of myelin oligodendrocyte glycoprotein antibody spectrum disorder remains to be fully elucidated. We describe the case of a 9-year-old boy with immune-mediated myelitis undetectable by conventional magnetic resonance imaging in the context of relapsing anti-myelin oligodendrocyte glycoprotein spectrum disorder. Despite the severe clinical presentation, his symptoms improved significantly following treatment with corticosteroids. Because timely diagnosis and treatment is imperative to prevent disease recurrence and reduce long-term morbidity, serum anti-myelin oligodendrocyte glycoprotein antibody testing should be considered in all children with acute demyelinating syndromes and unusual clinical presentations-including seizures-both at presentation and at follow-up.

ABSTRACT

OBJECTIVE: The objective of the study was to explore the association between physical fitness and the likelihood of acute coronary syndrome (ACS) in patients presenting to the emergency department (ED) with chest pain (CP). We hypothesized that the likelihood of ACS would be lower in physically fit patients and higher in patients with exercise-induced CP. METHODS: The study involved a prospective, descriptive cohort in an academic suburban ED. Subjects were ED patients with CP admitted for suspected ACS. Demographic and clinical data were collected by trained research assistants using standardized forms. Patients were surveyed on level of fitness and whether they had ever experienced anginal type symptoms during exercise. Acute coronary syndrome was considered present if the patient had electrocardiographic evidence of infarction or ischemia; elevated troponin I levels; greater than 70% stenosis of culprit coronary artery; or a positive nuclear, echocardiographic, or treadmill stress test result. Patients readmitted within 30 days for reinfarction, cardiogenic shock, or arrhythmias were also considered to have ACS. The association between physical fitness and ACS was determined using χ(2) tests and odds ratios (ORs). RESULTS: One hundred patients were enrolled. Mean age was 55.8 (±15.3) years; 36% were female; 85% were white. Thirteen (13%) patients had positive troponins, 22 of 36 catheterized patients had greater than 70% coronary artery stenosis, and 6 (6%) had abnormal stress test results. There were no deaths or reinfarctions within 30 days. The rate of ACS was similar in patients who were physically fit and those who were not (24% vs 37%; OR, 0.5 [95% confidence interval, 0.2-1.3]) and in patients who had experienced exercise-induced CP and those who had not (32% vs 29%; OR, 1.2 [95% confidence interval, 0.4-3.2]). Neither the frequency nor the intensity of exercise was associated with ACS. CONCLUSIONS: Physically fit patients with CP were as likely to have ACS as those not physically fit. A history of exercise-induced CP was not associated with an increased likelihood of ACS.

ABSTRACT

OBJECTIVES: Reliance upon patient assessment in excluding pregnancy is questionable. Physicians are encouraged to obtain pregnancy tests in all women of childbearing age. We affirmed the accuracy of women and their physicians in predicting pregnancy. METHODS: This was a prospective, observational study performed in a suburban academic emergency department on adult women with an ordered pregnancy test. A standardized gynecologic history was obtained by trained research assistants. Subjects estimated their likelihood of pregnancy as impossible, possible, or definite. Emergency department physicians estimated the likelihood of pregnancy as high, moderate, or low. All women had either a serum or urine ß-human chorionic antigen. The diagnostic characteristics of patient and physician predictions of pregnancy were calculated with 95% confidence intervals (CIs). RESULTS: We enrolled 377 subjects. Median age was 29 (interquartile range, 22-37) years. Twelve percent of the women were pregnant. Women's estimates of pregnancy were as follows: impossible, 64.7%; possible, 22.5%; and definite, 12.7%. The pregnancy rates among women with estimates of impossible, possible, and definite were 0% (95% CI, 0%-1.5%), 4.7% (95% CI, 1.9%-11.5%), and 89.6% (95% CI, 77.8%-95.5%) (P < .001). Physicians' suspicions of pregnancy were high (13.7%), moderate (11.3%), and low (75.1%). The rate of pregnancy among low, moderate, and high physician suspicion groups were 0% (95% CI, 0%-1.4%), 9.5% (95% CI, 3.8%-22%), and 84.3% (95% CI, 72%-92%) (P < .001). CONCLUSIONS: There were no pregnancies among women who estimated pregnancy as impossible or whose physicians thought that the likelihood of pregnancy was low. Routine pregnancy testing before radiological imaging and medication administration may not be required in adult women of childbearing age.

ABSTRACT

Fatigue and quality of life are significant concerns in adult multiple sclerosis (MS) but little is known about these factors in pediatric MS. The present investigation evaluates fatigue and quality of life in 51 pediatric MS patients to determine the rate of fatigue and reduced quality of life and assesses the relations between these variables and clinical factors. Fatigue and quality of life were assessed by self- and parent-report via the PedsQL Multidimensional Fatigue Scale and the PedsQL Quality of Life Scale. One-sample t-tests determined if scores were below published data for healthy individuals. Moreover, scores falling one standard deviation from norms were considered mildly affected, with severe difficulties being defined as scores falling two or more standard deviations from norms. Associations between self- and parent-reported difficulties and clinical factors were examined via Pearson correlation analyses. In comparison with healthy samples, pediatric MS patients reported greater difficulties with respect to fatigue, sleep, cognition, physical limitations, and academics. In addition to significant difficulties on these factors, parents reported problems with respect to emotional functioning, and tended to report greater fatigue, sleep, and cognitive difficulties than were self-reported. Expanded Disability Status Scale score was the only neurologic variable significantly related to fatigue or quality of life scores. Fatigue was significantly correlated with reports of sleep difficulties, cognitive problems, and quality of life variables. These findings suggest that fatigue and poorer quality of life is a clear concern in pediatric MS, and is related to overall physical disability.

ABSTRACT

Baseline predictors of cognitive change were explored in a sample of persons with multiple sclerosis (MS). Potential predictors included demographic features, baseline clinical characteristics, and psychological state. Participants were 38 individuals diagnosed with either relapsing remitting or secondary progressive MS who did not meet criteria for a current major depressive episode. Subjects were tested at baseline and approximately 1 year in an ongoing longitudinal study of cognition in MS. Participants completed neuropsychological tests sensitive to impairment in MS. They also completed self-report measures of depression, anxiety, fatigue, apathy, and positive and negative affect. Baseline measures of negative affect (e.g., depressed mood, state anxiety, and negative affective state) consistently predicted cognitive change over the course of the study. Higher baseline levels of negative affect were associated with greater relative declines in cognitive performance. This longitudinal relation occurred in the absence of a cross-sectional relation between negative affect and overall cognition. High baseline negative affect particularly predicted a relative decline in episodic memory for newly learned verbal and visuospatial information. The negative affect measures were unique in their predictive value among all the baseline measures assessed. (JINS, 2009, 15, 53-61.).

ABSTRACT

STUDY OBJECTIVE: Ingestion of diatrizoate meglumine before abdominal computed tomography (CT) is time consuming. We hypothesized that pretreatment with metoclopramide or ondansetron would result in faster ingestion of diatrizoate meglumine than placebo. METHODS: The study was a double-blind, randomized controlled trial on adults requiring oral contrast abdominal CT. Patients were randomized to placebo, metoclopramide 10 mg, or ondansetron 4 mg intravenously 15 minutes before ingesting 2 L of diatrizoate meglumine. The primary outcome was time to complete diatrizoate meglumine ingestion. Secondary outcome measures included volume of diatrizoate meglumine ingested, 100-mm visual analog scale for nausea at 15-minute intervals, time to CT, vomiting, and use of rescue antiemetics. The study was powered to detect a 60-minute difference in diatrizoate meglumine ingestion time between saline and medication groups. RESULTS: One hundred six patients were randomized; placebo (36), metoclopramide (35), and ondansetron (35). Groups were similar in baseline characteristics. Median (interquartile range) times for diatrizoate meglumine ingestion were placebo 109 minutes (82 to 135 minutes); metoclopramide 105 minutes (75 to 135 minutes); and ondansetron 110 minutes (79 to 140 minutes) (P=.67). Vomiting was less frequent with metoclopramide (3%) than placebo (18%) or ondansetron (9%) (P=.11). The visual analog scale for nausea at each point was not significantly different between groups (P=.11). The need for rescue antiemetics was lowest for metoclopramide (3%) compared with placebo (27%) and ondansetron (12%) (P=.02). CONCLUSION: Pretreatment with ondansetron or metoclopramide does not reduce oral contrast solution ingestion time.
