The Integrated Behavior Therapy for Children with Selective Mutism: Findings from an open pilot study in a naturalistic setting.

To test the hypothesis that the Integrated Behavior Therapy for Children with Selective Mutism (IBTSM), administered in a naturalistic setting, is (a) a feasible and acceptable treatment, (b) effective in reducing children's selective mutism (SM) and social anxiety (SA) symptoms, and (c) effective in reducing parents' accommodation behaviors to their children's anxiety. This was an open, uncontrolled trial with assessments at baseline, first session, and post-treatment. The study treated 30 children aged 4-13, using the IBTSM protocol. The diagnosis of SM was established by psychologists using a structured interview. The parents reported levels of SM, SA, and parental accommodation on questionnaires, and the level of children's global functioning was rated by clinicians. Feasibility and acceptability of the IBTSM were assessed using dropout rates, protocol adherence, adverse events, and therapist's acceptability ratings. The IBTSM had acceptable dropout rates, with no adverse events and high acceptability rates. Following IBTSM, children's SM and SA levels, and parents' accommodation, significantly decreased. 75% of children were rated by clinicians as treatment responders. IBTSM is a feasible, acceptable, and efficacious treatment for children with SM, utilized in clinical settings. The results of this open trial must be replicated in randomized controlled studies.

Diagnostic Accuracy of Point-of-Care Gastric Ultrasound.

BACKGROUND: Pulmonary aspiration of gastric contents is associated with significant perioperative morbidity and mortality. Previous studies have investigated the validity, reliability, and possible clinical impact of gastric ultrasound for the assessment of gastric content at the bedside. In the present study, we examined the accuracy (evaluated as sensitivity, specificity, and likelihood ratios) of point-of-care gastric ultrasound to detect a "full stomach" in a simulated scenario of clinical equipoise. METHODS: After a minimum fasting period of 8 hours, 40 healthy volunteers were randomized in a 1:1 ratio to either remain fasted or ingest a standardized quantity of clear fluid or solid. Each subject was randomized twice on 2 independent study sessions at least 24 hours apart. A gastric ultrasound examination was performed by a blinded sonographer following a standardized scanning protocol. Using a combination of qualitative and quantitative findings, the result was summarized in a dichotomous manner as positive (any solid or >1.5 mL/kg of clear fluid) or negative (no solid and ≤1.5 mL/kg of clear fluid) for full stomach. RESULTS: Data from 80 study sessions were analyzed. In this simulated clinical scenario with a pretest probability of 50%, point-of-care gastric ultrasound had a sensitivity of 1.0 (95% confidence interval [CI], 0.925-1.0), a specificity of 0.975 (95% CI, 0.95-1.0), a positive likelihood ratio of 40.0 (95% CI, 10.33-∞), a negative likelihood ratio of 0 (95% CI, 0-0.072), a positive predictive value of 0.976 (95% CI, 0.878-1.0), and a negative predictive value of 1.0 (95% CI, 0.92-1.0). CONCLUSIONS: Our results suggest that bedside gastric ultrasound is highly sensitive and specific to detect or rule out a full stomach in clinical scenarios in which the presence of gastric content is uncertain.

Folate and neural tube defects: The role of supplements and food fortification.

Periconceptional folic acid significantly reduces the risk of neural tube defects. It is difficult to achieve optimal levels of folate by diet alone, even with fortification of flour, especially because flour consumption in Canada is slightly decreasing. Intermittent concerns have been raised concerning possible deleterious effects of folate supplementation, including the masking of symptoms of vitamin B12 deficiency and an association with cancer, especially colorectal cancer. Both concerns have been disproved. The Canadian Paediatric Society endorses the following steps to enhance folate intake in women of child-bearing age: encouraging the consumption of folate-rich foods such as leafy vegetables, increasing the level of folate food fortification, taking a supplement containing folate and B12, and providing free folate supplementation to disadvantaged women of child-bearing age. These recommendations are consistent with those of the Society of Obstetricians and Gynaecologists of Canada.

La consommation d'acide folique pendant la période périconcep- tionnelle réduit considérablement le risque d'anomalie du tube neural. Il est difficile d'atteindre un taux optimal de folate à partir du seul régime alimentaire, malgré l'enrichissement de la farine, surtout que la consommation de ce produit diminue légèrement au Canada. Les effets délétères possibles des suppléments de folate ont suscité sporadiquement des inquiétudes, y compris le camouflage des symptômes de carence en vitamine B12 et une association avec le cancer, surtout colorectal. Ces deux inquiétudes ont été réfutées. La Société canadienne de pédiatrie appuie les mesures suivantes pour accroître la consommation de folate chez les femmes défavorisées en âge de procréer : encourager la consommation d'aliments riches en folate, comme les légumes-feuilles, accroître le taux d'enrichissement des aliments en folate, prendre un supplément contenant du folate et de la vitamine B12 et distribuer gratuitement des suppléments de folate. Ces recommandations concordent avec celles de la Société des obstétriciens et gynécologues du Canada.

An Expedited Care Pathway with Ambulatory Brachial Plexus Analgesia Is a Cost-effective Alternative to Standard Inpatient Care after Complex Arthroscopic Elbow Surgery: A Randomized, Single-blinded Study.

BACKGROUND: Common standard practice after complex arthroscopic elbow surgery includes hospital admission for 72 h. The authors hypothesized that an expedited care pathway, with 24 h of hospital admission and ambulatory brachial plexus analgesia and continuous passive motion at home, results in equivalent elbow range of motion (ROM) 2 weeks after surgery compared with standard 72-h hospital admission. METHODS: A randomized, single-blinded study was conducted after obtaining approval from the research ethics board. Forty patients were randomized in a 1:1 ratio using a computer-generated list of random numbers into an expedited care pathway group (24-h admission) and a control group (72-h admission). They were treated equally aside from the predetermined hospital length of stay. RESULTS: Patients in the control (n = 19) and expedited care pathway (n = 19) groups achieved similar elbow ROM 2 weeks (119 ± 18 degrees and 121 ± 15 degrees, P = 0.627) and 3 months (130 ± 18 vs. 130 ± 11 degrees, P = 0.897) postoperatively. The mean difference in elbow ROM at 2 weeks was 2.6 degrees (95% CI, -8.3 to 13.5). There were no differences in analgesic outcomes, physical function scores, and patient satisfaction up to 3 months postoperatively. Total hospital cost of care was 15% lower in the expedited care pathway group. CONCLUSION: The results suggest that an expedited care pathway with early hospital discharge followed by ambulatory brachial plexus analgesia and continuous passive motion at home is a cost-effective alternative to 72 h of hospital admission after complex arthroscopic elbow surgery.

Chronic Pain Assessment Tools for Cerebral Palsy: A Systematic Review.

BACKGROUND AND OBJECTIVE: Chronic pain in children with cerebral palsy (CP) is underrecognized, leading to detriments in their physical, social, and mental well-being. Our objective was to identify, describe, and critique pediatric chronic pain assessment tools and make recommendations for clinical use for children with CP. Secondly, develop an evidence-informed toolbox to support clinicians in the assessment of chronic pain in children with disabilities. METHODS: Ovid Medline, Cumulative Index to Nursing and Allied Health Literature, and Embase databases were systematically searched by using key terms "chronic pain" and "clinical assessment tool" between January 2012 and July 2014. Tools from multiple pediatric health conditions were explored contingent on inclusion criteria: (1) children 1 to 18 years; (2) assessment focus on chronic pain; (3) psychometric properties reported; (4) written in English between 1980 and 2014. Pediatric chronic pain assessment tools were extracted and corresponding validation articles were sought for review. Detailed tool descriptions were composed and each tool underwent a formal critique of psychometric properties and clinical utility. RESULTS: Of the retrieved 2652 articles, 250 articles met eligibility, from which 52 chronic pain assessment tools were retrieved. A consensus among interprofessional working group members determined 7 chronic pain interference tools to be of importance. Not all tools have been validated with children with CP nor is there 1 tool to meet the needs of all children experiencing chronic pain. CONCLUSIONS: This study has systematically reviewed and recommended, through expert consensus, valid and reliable chronic pain interference assessment tools for children with disabilities.

Intravenous dexamethasone and perineural dexamethasone similarly prolong the duration of analgesia after supraclavicular brachial plexus block: a randomized, triple-arm, double-blind, placebo-controlled trial.

BACKGROUND AND OBJECTIVES: Perineural dexamethasone prolongs the duration of single-injection peripheral nerve block when added to the local anesthetic solution. Postulated systemic mechanisms of action along with theoretical safety concerns have prompted the investigation of intravenous dexamethasone as an alternative, with decidedly mixed results. We aimed to confirm that addition of intravenous dexamethasone will prolong the duration of analgesia after single-injection supraclavicular block compared with conventional long-acting local anesthetic alone or in combination with perineural dexamethasone for ambulatory upper extremity surgery. METHODS: Seventy-five patients were randomized to receive supraclavicular block using 30-mL bupivacaine 0.5% alone (Control), with concomitant intravenous dexamethasone 8 mg (DexIV), or with perineural dexamethasone 8 mg (DexP). Duration of analgesia was designated as the primary outcome. To test our hypothesis, the superiority of DexIV was first compared with Control and then with DexP. Motor block duration, pain scores, opioid consumption, opioid-related side effects, patient satisfaction, and block-related complications were also analyzed. RESULTS: Twenty-five patients per group were analyzed. The duration of analgesia (mean [95% confidence interval]) was prolonged in the DexIV group(25 hours [17.6­32.4]) compared with Control (13.2 hours [11.5­15.0]; P < 0.001) but similar to the DexP group (25 hours[19.5­30.5]; P = 1). [corrected] Both DexIV and DexP had reduced pain scores, reduced postoperative opioid consumption, and improved satisfaction compared with Control. CONCLUSIONS: In a single-injection supraclavicular block with long-acting local anesthetic, the effectiveness of intravenous dexamethasone in prolonging the duration of analgesia seems similar to perineural dexamethasone.

Infection related to ultrasound-guided single-injection peripheral nerve blockade: a decade of experience at toronto Western hospital.

The use of ultrasound guidance has revolutionized regional anesthesia practice. Ultrasound equipment disinfection techniques vary between institutions. To date, there are no large data set publications or evidence-based guidelines that describe risk-reduction techniques for infectious complications related to the use of ultrasound guidance for peripheral nerve blockade. We retrospectively reviewed the medical charts of 7476 patients who received ultrasound-guided single-injection peripheral nerve blockade from October 2003 to August 2013 using our institution's low-level disinfection technique in combination with a sterile transparent film barrier dressing to cover the ultrasound transducer. No indications of block-related infection were found. We conclude that using a practical and efficient low-level disinfection technique and sterile barrier dressing results in an extremely low rate of block-related infection following ultrasound-guided single-injection peripheral nerve blockade.
