OBJECTIVES

Abdominal pain is a common pediatric complaint to emergency departments (EDs), and clinicians often rely on imaging for diagnosis. Studies have demonstrated an increase in computed tomography (CT) in this population. Following emphasis on radiation reduction by researchers and organizations, this study evaluates recent national trends in CT use among pediatric patients presenting to EDs with abdominal pain.

METHODS

This is a cross-sectional analysis of ED patients 18 years or younger with chief complaint of abdominal pain in the National Hospital Ambulatory Medical Care Survey from 2008 to 2011. Outcomes include annual proportions of visits with x-ray, ultrasound, or CT, as well as diagnosis of appendicitis and hospital admission.

RESULTS

Of 32,304 ED visits, 2120 (6.6%) were for abdominal pain. Proportions of visits using CT, ultrasound, and plain x-ray were 16.0%, 10.5%, and 23.4%, respectively. For all outcome measures, including imaging, hospital admission, and diagnosis of appendicitis, there was no change from 2008 to 2011. Considering previous data, there was a significant rise in ultrasound use from 5.4% (95% confidence interval, 2.4%-8.4%) in 1998 to 12.1% (95% confidence interval, 9.4%-13.7%) in 2011. Multivariate analysis of CT use found the strongest predictor to be increasing age. Females, black children, and those with Medicaid insurance had lower odds of having a CT.

CONCLUSIONS

In contrast to the earlier dramatic increase in CT use for pediatric patients with abdominal pain, CT remained constant between 2008 and 2011. There was no associated change in the rate of diagnosis of appendicitis or hospitalization; however, ultrasound is increasing.

Extensively drug-resistant tuberculosis (XDR TB) has extremely poor treatment outcomes in adults. Limited data are available for children. We report on clinical manifestations, treatment, and outcomes for 37 children (<15 years of age) with bacteriologically confirmed XDR TB in 11 countries. These patients were managed during 1999-2013. For the 37 children, median age was 11 years, 32 (87%) had pulmonary TB, and 29 had a recorded HIV status; 7 (24%) were infected with HIV. Median treatment duration was 7.0 months for the intensive phase and 12.2 months for the continuation phase. Thirty (81%) children had favorable treatment outcomes. Four (11%) died, 1 (3%) failed treatment, and 2 (5%) did not complete treatment. We found a high proportion of favorable treatment outcomes among children, with mortality rates markedly lower than for adults. Regimens and duration of treatment varied considerably. Evaluation of new regimens in children is required.

Tobacco use is the leading lifestyle-related cause of death in the United States. We analyzed correlates of smoking and vaping tobacco in the National HIV Behavioral Surveillance (NHBS) among men who have sex with men (MSM) in San Francisco in 2014 ( n = 410) using multivariable logistic regression models. We found that more than two in five MSM (41%) smoked or vaped. Smoking was greater for men of color (46% vs. 35%; p = .02); those with annual income below $50,000 (47% vs. 34%; p = .01); those without a college education (51% vs. 30%; p < .01); and the uninsured (55% vs. 38%; p = .04). In multivariable analyses, greater odds of smoking were observed among men living with HIV (adjusted odds ratio [aOR] = 1.7; 95% CI [1.00, 2.8]); men who reported cocaine use (aOR = 3.1; 95% CI [1.9, 5.0]), and men who reported greater number of alcohol drinks on a drinking day (aOR = 1.2; 95% CI [1.05, 1.29]). Lower odds of smoking were observed for men who completed college (aOR = 0.57; 95% CI [0.36, 0.88]). Greater odds of vaping were observed among men who reported meth use (aOR = 3.01; 95% CI [1.65, 5.50]). Lower odds of vaping were observed among men who completed college (aOR = 0.55; 95% CI [0.32, 0.98]). In conclusion, the prevalence of smoking and vaping among MSM is extremely high, particularly HIV-positive MSM. MSM who smoked and vaped were more likely to be racial and ethnic minorities, have lower socioeconomic status, and report more substance and alcohol use. These findings highlight the need to develop strategies effectively addressing the high rates of cigarette smoking and vaping among MSM, particularly among minority MSM and MSM living with HIV.
