Measuring Anxiety in the Pediatric Emergency Department.

OBJECTIVES: The objective of this study was to evaluate the agreement between the State Trait Anxiety Inventory (STAI) and other anxiety scales to determine whether these shorter to administer scales could replace the STAI. METHODS: This was a prospective cohort study on a convenience sample of children, aged 9 to 17 years, presenting to a pediatric emergency department. Patients were divided into 2 groups: preteens (PT) (aged 9-12 years) completed the pediatric STAI and teens (T) (aged 13-17 years) completed the adult STAI. Participants also completed a visual analog scale (0-100 mm), a Likert scale (1-5), and a short version of the STAI. Intraclass correlation (2-way mixed model, average measures) was used to evaluate agreement between the STAI and the other scales. A sample size of 100 patients per group was estimated as sufficient. RESULTS: The median (interquartile range) STAI state anxiety scores were 33 (28.25-36.75) and 37.5 (32-44), in the PT (n = 100) and T (n = 100) groups, respectively. The median (interquartile range) STAI trait anxiety scores were 33.5 (28-38.75) and 36 (31-44), in the PT and T groups, respectively. Agreements between the STAI and the other scales were poor for all scales. At best, the intraclass correlation was 0.71 for the agreement between the STAI and the short version of the STAI. CONCLUSIONS: There appears to be poor agreement between the STAI and the other scales designed to measure anxiety in children 9 to 17 years presenting to the pediatric emergency department.

Pediatric Spontaneous Pneumomediastinum: Narrative Literature Review.

INTRODUCTION: Described since 1939 in the adult population, spontaneous pneumomediastinum is less known in children. Because of its symptoms and a generally benign evolution, it is probably an underestimated diagnosis. However, it has to be considered in the differential diagnosis of acute thoracic pain. METHODS: The incidence being low, we conducted a narrative literature review to identify the circumstances leading to a spontaneous pneumomediastinum, the most relevant signs and symptoms, investigations, as well as treatment recommendations. RESULTS: Of 216 patients, 66.2% are boys, and mean ages range from 6.9 to 14 years. The most frequent comorbidity in children is asthma (22.2%), and the most common trigger factors are bronchospasm (49%), cough (45.6%), various respiratory tract infections, vomiting (10.3%), and foreign body aspiration (8.3%). It remains idiopathic in 33.3%. Relevant signs are chest pain (54.6%), neck pain and/or sore throat (53.3%), and dyspnea (41.2%). The most relevant sign is palpation of subcutaneous emphysema (66.4%). The classically described Hamman crunch is only present in 11.6%. Chest x-ray provides the right diagnosis in 99.5% of the patients. Pneumothorax is associated in 11.6%. Most patients are hospitalized (88.3%); treatment is based on oxygen therapy, painkillers, and rest. In some series, there can be up to 25.8% of patients requiring intensive care and 5.5% requiring drainage of associated pneumothorax. Survival rate is 92.5%, and long-term follow-up shows normal x-rays after 4 days and no recurrence. CONCLUSIONS: Spontaneous pneumomediastinum is uncommon in children but must be considered in pediatric patients with acute chest and/or neck pain. History taking, physical examination, and standard chest x-ray are most often diagnostic, and there is rarely a need for other investigation.Hospitalization is not always indispensable; ambulatory management can be considered. Outcome is good, and follow-up can be clinical, therefore avoiding further x-rays.
