Oesophageal apoplexy or intramural haematoma of the oesophagus (IHE) is a rare condition with a pattern of presentation that can mimic sinister pathologies. Diagnosis requires a high index of suspicion, and the exclusion of an oesophageal perforation or oesophageal malignancy is important. Investigations include computer topography (CT) and contrast swallow studies as well as a gastroscopy. Management is mainly supportive with resolution of symptoms typically occurring rapidly. We present two cases of this rare condition, with accompanying images.

OBJECTIVE: Emergency department use of ondansetron in children with gastroenteritis is increasing; however, its effect on clinical outcomes is unknown. We aimed to determine whether increasing ondansetron usage is associated with improved outcomes in children with gastroenteritis. METHODS: A retrospective cohort study was conducted at The Hospital for Sick Children, Toronto, Canada. Eligible children included those younger than 18 years old with gastroenteritis who presented to an emergency department between 2003 and 2008. There were 22,125 potentially eligible visits; 20% were selected at random for chart review. The primary outcome measure, the intravenous rehydration rate, was evaluated using an interrupted time-series analysis with segmented logistic regression. Secondary outcomes included emergency department revisits, hospitalization, and length of stay. RESULTS: A total of 3508 patient visits were included in the final analysis. During the study period, there was a significant reduction in intravenous rehydration usage (27%-13%; Pâ<â0.001) and an increase in ondansetron administration (1%-18%; Pâ<â0.001). Time-series analysis demonstrated a level break (Pâ=â0.03) following the introduction of ondansetron. The mean length of stay for children declined from 8.6â±â3.4 to 5.9â±â2.8âhours, Pâ=â0.03. During the week following the index visit, there was a reduction in return visits (18%-13%; Pâ=â0.008) and need for intravenous rehydration (7%-4%; Pâ=â0.02). CONCLUSIONS: Ondansetron use has increased significantly and is associated with reductions in the use of intravenous rehydration, emergency department revisits, and length of stay. The selective use of ondansetron is associated with improved clinical outcomes.

BACKGROUND: Past varicella infection (chicken pox) may reactivate into herpes zoster (shingles). Varicella vaccination leads to a reduction in cases of varicella that may in turn increase herpes zoster rates due to reduction in the immune boosting effect of exposure to varicella zoster virus against varicella reactivation. We assessed the impact of childhood varicella vaccination in Ontario, Canada on zoster incidence and healthcare visits, and established baseline zoster rates prior to zoster vaccine introduction. METHODS: We used population-based, administrative databases to identify zoster incidence and healthcare use from April 1992 to March 2010. RESULTS: After routine varicella vaccination, zoster incidence rates decreased 29% for children aged 0-9 and changed minimally for other ages. Age-standardized rates of hospitalizations during the study period declined by 53%, while outpatient rates declined by 9%. The annual zoster incidence for those 60 or older was 740 per 100,000. CONCLUSIONS: In the early post-varicella vaccination period, incidence rates of medically attended herpes zoster did not increase for the overall population and decreased moderately for children 9 years and younger, the age group targeted for varicella vaccination.

OBJECTIVE: This study examined the mechanisms of injury and the pattern of care for children who presented to the emergency department with uncomplicated nail bed lacerations. METHODS: A retrospective chart review was conducted from January 2004 to December 2007 for all children younger than 18 years who presented to a tertiary children's hospital with an uncomplicated nail bed laceration. RESULTS: There were 84 cases of uncomplicated nail bed injuries for more than a 4-year period. Sixty percent of the subjects were males. The mean age was 5.3 (SD, 4.1) years. Most injuries occurred at home (58%), and the most common mechanism of injury was a door (67%). Approximately 40% of patients were treated by emergency physicians. There was no significant difference in acute and chronic complications or in the length of stay in the emergency department, between patients treated by emergency physicians and by plastic surgeons. CONCLUSIONS: Most nail bed injuries in children occur at home, and the door seems to be the major mechanism of injury. Approximately 57% of these are children younger than 5 years. Only 42% of uncomplicated nail bed lacerations are treated by emergency physicians, yet there is no significant difference in outcomes between plastic surgeons and emergency physicians. Our study suggests that there is a role in public education for primary prevention, and with proper training, pediatric emergency physicians can treat uncomplicated nail bed lacerations.

BACKGROUND: The use of antiemetics for children with vomiting is one of the most controversial decisions in the treatment of gastroenteritis in developed countries. Ondansetron, a selective serotonin receptor antagonist, has been found to be effective in improving the success of oral rehydration therapy. However, North American and European clinical practice guidelines continue to recommend against its use, stating that evidence of cost savings would be required to support ondansetron administration. Thus, an economic analysis of the emergency department administration of ondansetron was conducted. The primary objective was to conduct a cost analysis of the routine administration of ondansetron in both the United States and Canada. METHODS AND FINDINGS: A cost analysis evaluated oral ondansetron administration to children presenting to emergency departments with vomiting and dehydration secondary to gastroenteritis from a societal and health care payer's perspective in both the US and Canada. A decision tree was developed that incorporated the frequency of vomiting, intravenous insertion, hospitalization, and emergency department revisits. Estimates of the monetary costs associated with ondansetron use, intravenous rehydration, and hospitalization were derived from administrative databases or emergency department use. The economic burden in children administered ondansetron plus oral rehydration therapy was compared to those not administered ondansetron employing deterministic and probabilistic simulations. We estimated the costs or savings to society and health care payers associated with the routine administration of ondansetron. Sensitivity analyses considered variations in costs, treatment effects, and exchange rates. In the US the administration of ondansetron to eligible children would prevent approximately 29,246 intravenous insertions and 7,220 hospitalizations annually. At the current average wholesale price, its routine administration to eligible children would annually save society US$65.6 million (US$49.1-US$81.1) and health care payers US$61.1 million (US$46.2-US$76.3). In Canada the administration of ondansetron to eligible children would prevent 4,065 intravenous insertions and 1,003 hospitalizations annually. Its routine administration would annually save society CDN$1.72 million (CDN$1.15-CDN$1.89) and the health care system CDN$1.18 million (CDN$0.88-CDN$1.41). CONCLUSIONS: In countries where intravenous rehydration is often employed, the emergency department administration of oral ondansetron to children with dehydration and vomiting secondary to gastroenteritis results in significant monetary savings compared to a no-ondansetron policy.

Varicella vaccines have been available for private purchase in Canada since 1998. Ontario introduced publicly funded varicella vaccination in 2004. We assessed the effects of private availability of varicella vaccines and subsequent implementation of a publicly funded vaccination program on varicella-related hospitalizations, emergency department (ED) use, and visits to physicians' offices in Ontario. Rates of hospitalizations, ED use, and office visits decreased 53% (95% CI, 48-58%), 43% (95% CI, 41-44%), and 45% (95% CI, 44-45%) after publicly funded vaccination, compared to only 9% (95% CI, 4-14%), 23% (95% CI, 22-24%), and 29% (95% CI, 28-29%) after private availability. Varicella vaccination is effective at reducing varicella-related health care use, with benefits extending beyond those who receive the vaccine. Publicly funded vaccination programs may be more effective than private vaccine availability.
