Comparison of Oropharyngeal Dysphagia Before and After Botulinum Toxin Injection in Cervical Dystonia.

Cervical dystonia (CD) is the most common form of focal dystonia with Botulinum neurotoxin (BoNT) being a frequent method of treatment. Dysphagia is a common side effect of BoNT treatment for CD. Instrumental evaluation of swallowing in CD using standardized scoring for the videofluoroscopic swallowing study (VFSS) and validated and reliable patient-reported outcomes measures is lacking in the literature. (1) to determine if BoNT injections change instrumental findings of swallowing function using the Modified Barium Swallow Impairment Profile (MBSImP) in individuals with CD; (2) to determine if BoNT injections change self-perception of the psychosocial handicapping effects of dysphagia in individuals with CD, using the Dysphagia Handicap Index (DHI); (3) to determine the effect of BoNT dosage on instrumental swallowing evaluation and self-reported swallowing outcomes measures. 18 subjects with CD completed a VFSS and the DHI before and after BoNT injection. There was a significant increase in pharyngeal residue for pudding consistency after BoNT injection, p = 0.015. There were significant positive associations between BoNT dosage and self-perception of the physical attributes of the handicapping effect of dysphagia, the grand total score and patient self-reported severity of dysphagia on the DHI; p = 0.022; p = 0.037; p = 0.035 respectively. There were several significant associations between changes in MBSImP scores and BoNT dose. Pharyngeal efficiency of swallowing may be affected by BoNT for thicker consistencies. Individuals with CD perceive greater physical handicapping effects of dysphagia with increased amounts of BoNT units and have greater self-perceptions of dysphagia severity with increased amounts of BoNT units.

Navigating chronic pain: how taking a few wrong turns can miss sinister pathology.

Bone sarcomas are rare in childhood, and their presentation can often mimic more benign complaints or chronic musculoskeletal pain. Ewing sarcomas in particular are often diagnosed after a significant delay from the onset of symptoms. At a population level, a long diagnostic delay is not necessarily associated with worse survival , as tumours that display slow growth also tend to be less aggressive. For any specific individual however, a delayed diagnosis can result in a larger tumour that is more difficult to treat. We explore a case of Ewing sarcoma and discuss how the presenting features, approach to imaging and the role of clinician cognitive bias may have led to diagnostic delay.Ewing sarcoma is treated with chemotherapy and surgery and/or radiotherapy based on the initial site of disease, size of tumour and response to initial treatment. With current UK treatments, overall survival is approximately 70% for localised tumours and up to 20% in those with metastatic disease. Bone sarcomas usually present with deep-seated mechanical bone pain akin to toothache. The pain can be intermittent over the course of days or weeks, but pain occurring at night should be considered a red flag. Swelling may also present. On plain X-ray, bone sarcomas can demonstrate areas of bone destruction, new bone formation, periosteal inflammation and soft tissue swelling, but in some cases the changes are very subtle. Persistent unexplained symptoms require MRI to exclude tumours and detect potential benign causes that are amenable to treatment.

Tiered curriculum in global child health: A novel CanMEDs-based multidisciplinary educational program.

Despite the importance of Global Child Health to the practice of 21st century paediatricians, formal comprehensive outcomes-based curricula in this area are lacking. This article describes the development and implementation of a novel, tiered, CanMEDs-based and multidisciplinary curriculum in Global Child Health that was based on a thorough review of the literature. In addition to detailing the steps and results of our literature review, we discuss the three tiers of our curriculum (General Track, Advanced Curriculum and Elective Track) as well as the evidence-informed curricular topics and learning outcomes associated with each tier. Moreover, we highlight the importance of a multidisciplinary approach to Global Child Health education and the potential for this work to help transition Global Child Health training to competency-based models of teaching and learning. This review may help hospitals and residency programs across Canada looking to develop more formal curricula in this often overlooked area.

The Waiting Room Assessment to Virtual Emergency Department pathway: Initiating video-based telemedicine in the pediatric emergency department.

The COVID-19 pandemic has presented pediatric emergency departments with unique challenges, resulting in a heightened demand for adapted clinical pathways. In response to this need, the Montreal Children's Hospital pediatric emergency department introduced the WAVE (Waiting Room Assessment to Virtual Emergency Department) pathway, a video-based telemedicine pathway for selected non-critical patients, aiming to reduce safety issues related to emergency department overcrowding, while providing timely care to all children presenting and registering at our emergency department. The objective of the WAVE pilot phase was to evaluate the feasibility and acceptability of telemedicine in our pediatric emergency department, which was previously unfamiliar with this mode of care delivery. During the six-week, three-evening per week deployment, we conducted 18 five-hour telemedicine shifts. In total, 27 patients participated in the WAVE pathway. Results from this pilot phase met four of five a priori feasibility and acceptability criteria. Overall, participating families were satisfied with this novel care pathway and reported no disruptive technological barriers.

Chameleon project: a children's end-of-life care quality improvement project.

In response to there being no specialist paediatric palliative care (PPC) team in a region of England, we undertook a 12-month quality improvement project (funded by National Health Service England's Marginal Rate Emergency Threshold and Readmission fund) to improve children's end-of-life care.Improvements were implemented during two plan-do-study-act (PDSA) cycles and included specialist experts, clinical champions, focused education and training, and tools and materials to support identification, care planning and communication. A lead paediatrician with expertise in PPC (10 hours/week) led the project, supported by a PPC nurse (3 days/week) and a network administrator (2 days/week).Children who died an expected death were identified from the child death review teams. Numbers of non-elective hospital admissions, bed days, and costs were identified.Twenty-nine children died an expected death during the 12 months of the project and coincidentally 29 children died an expected death during the previous 12 months. The median number of non-elective admissions in the last 12 months of life was reduced from two per child to one. There was a reduction in specialist hospital (14%) and district general hospital (38%) bed days. The percentage of children who died an expected death who had anticipatory care plans rose from 50% to 72%.The results indicate that a network of clinicians with expertise in PPC working together across a region can improve personalised care planning and reduce admissions and bed days for children in their last year-of-life with reduced bed utilisation costs.

Predictors of tobacco use among persons with mental illnesses in a statewide population.

OBJECTIVE: This study used statewide administrative data sets to estimate the prevalence of tobacco use among persons with mental illnesses who were accessing public-sector mental health care in Colorado and to determine the relationships between tobacco use and primary diagnosis and alcohol and drug use. METHODS: This study utilized the Colorado Client Assessment Record to examine predictors of tobacco use among 111,984 persons with mental illnesses who were receiving services in the public mental health system. RESULTS: Thirty-nine percent of the sample (N=43,508) used tobacco. Multiple logistic regression analysis found that schizophrenia, schizoaffective disorder, and bipolar disorder (p<.001 for all), and depression or dysthymia (p<.01) were associated with greater tobacco use than other diagnoses. Significant differences in tobacco use existed across gender, age group, race or ethnicity, and substance use categories. CONCLUSIONS: Findings suggest that an administrative database is a low-burden means of identifying persons at high risk of tobacco use to inform resource allocation.

Adverse effects of therapy for ANCA-associated vasculitis.

The introduction of cyclophosphamide- and prednisolone-based treatment regimens has significantly improved outcome in patients with anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis. However, these regimens are nonspecific immunosuppressants associated with significant toxicity, including increased risk of infection, leucopenia, diabetes and malignancy. In addition, disease damage, particularly renal failure, increases the risk of toxicity. Improvements in disease management should include the increased awareness of treatment-related toxicity and its prevention.

Increased incidence of cardiovascular events in patients with antineutrophil cytoplasmic antibody-associated vasculitides: a matched-pair cohort study.

OBJECTIVE: To explore the risk of cardiovascular disease in patients with antineutrophil cytoplasmic antibody-associated vasculitides (AAVs) and to assess contributing risk factors. METHODS: In a retrospective matched-pair cohort study, 113 of 131 patients with AAVs from a vasculitis clinic registry were matched 1:1 for renal function, age at diagnosis, sex, smoking status, and previous history of a cardiovascular disease to patients with noninflammatory chronic kidney disease (CKD). Cardiovascular events were defined as acute coronary syndrome, new-onset angina, symptomatic peripheral vascular disease, stroke, and transient ischemic attack. RESULTS: Median followup times were 3.4 years for the AAV patients and 4.2 years for the CKD patients. More cardiovascular events occurred in the AAV group (23 of 113) than in the CKD group (16 of 113). Cox regression survival analysis showed a significantly increased risk of a cardiovascular event for AAV patients, with a hazard ratio (HR) of 2.23 (95% confidence interval [95% CI] 1.1-4.4) (P = 0.017). Within the cohort of AAV patients, the most strongly predictive factors were previous history of cardiovascular disease (HR 4 [95% CI 1.7-9.8]), history of dialysis dependency (HR 4.3 [95% CI 1.5-12.1]), ever having smoked (HR 3.9 [95% CI 1.5-10]), age at diagnosis (HR 1.038 [95% CI 1.006-1.072]), estimated glomerular filtration rate at remission (HR 0.977 [95% CI 0.957-0.998]), and serum cholesterol concentration at presentation (HR 0.637 [95% CI 0.441-0.92]). CONCLUSION: In this retrospective study, patients with AAVs appear at greater risk of cardiovascular disease, with increased risk in those with a previous history of cardiovascular disease, dialysis dependency, poor renal function at remission, or a history of smoking. Measures to reduce the risk of cardiovascular disease should be integral to the management of systemic vasculitis.
