Acute colonic diverticulitis typically occurs in patients older than 60 years of age but is uncommon in patients under the age of 40, which may lead to a delay in diagnosis. Because abdominal pain is a very common presenting symptom in emergency department patients, we retrospectively analyzed the cases of 21 patients 40 years of age and younger diagnosed with acute diverticulitis and characterized the presenting signs and symptoms, laboratory and radiographic findings, treatment, and outcome. There were 17 men and 4 women with a mean age of 34.1 +/-5.9 years. ⋯ All patients survived. In conclusion, acute diverticulitis is uncommon in patients under 40 years of age; however, this condition may be confused with other conditions, usually acute appendicitis. As a result, clinicians should consider acute diverticulitis in young patients with acute abdominal pain, especially if they are male with nausea, fever, tachycardia, and leukocytosis, and consider obtaining a CT scan to aid in the diagnosis.

Posterior shoulder dislocation is a relatively uncommon event, with an incidence of 1% to 4% of all shoulder dislocations. Because of the infrequency of this condition, the diagnosis is often missed, with significant consequences to the patient Injury in the athlete is usually from a direct blow or fall onto an outstretched arm. ⋯ A careful history and physical examination, complete radiographic evaluation, and a high level of suspicion are required to identify posterior shoulder dislocation. Treatment consists of prompt closed reduction, or operative repair if this is unsuccessful.

The objective of this study was to characterize population-based emergency medical service (EMS) use rates and examine some of the factors associated with usage of prehospital services. The design was a population-based observational study with multiple regression analysis. Transports reported by prehospital services to the Kentucky Emergency Medical Services Information System from Kentucky counties in which all EMS units submit computerized data was the data source. ⋯ In addition, the absence of 911 service (odds ratio [OR] 1.18, 95% confidence interval [CI; 1.14,1.22]) and the absence of a hospital in the county (OR 1.27, 95% CI [1.24,1.30]) were also associated with increasing rates of ambulance use. Rates of use of EMS are most dependent on age and cause, but use is also correlated with increasing levels of poverty. Wide variations in use between communities suggests that point estimates using one community may over- or underestimate EMS usage.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraosseous is faster and easier than umbilical venous catheterization in newborn emergency vascular access models.
The purpose of this study is to compare the speed and ease of establishing newborn emergency vascular access using intraosseous (IO) versus umbilical venous catheterization (UVC). The study is an experimental design. A total of 42 medical students, without prior IO and UVC experience, were recruited as study subjects. ⋯ Although UVC may be preferred by neonatologists, this model suggests that IO results in easier and more rapid vascular access in those who do not frequently perform newborn resuscitation. As such, the benefit of teaching UVC in pediatric resuscitation courses should be reconsidered. The recommended method of emergency newborn vascular access should be reconsidered pending further studies on this subject.
