Intussusception-associated hospitalization rates varied among the data sets and decreased substantially over time in the IHS data. Although intussusception-associated infant deaths in the United States have declined substantially over the past 2 decades, some deaths seem to be related to reduced access to, or delays in seeking, health care and are potentially preventable.intussusception, hospitalizations, deaths, risk factors, infants.

The outcomes of tuberculosis (TB) patients who move before completing antituberculosis treatment have not been described. We studied a population-based cohort of 2,576 adult patients reported as having TB in California during 1993, including 147 patients who moved from one local health jurisdiction to another within California. We determined treatment outcomes (completed, defaulted, died, other) for 131 (89%) of these 147 patients. Patients who moved defaulted more often (relative risk [RR] = 5.5, 95% confidence interval [CI] = 4.1 to 7.4) than patients who did not move. Including these patients' treatment outcomes increased the known number of defaulters by 30%, from 141 to 183 persons. Additionally, diagnosis of TB in a state prison emerged as the strongest risk factor for defaulting from treatment. Patients who moved or defaulted were more likely to abuse drugs or alcohol, to be homeless or to be associated with congregate settings such as jails and prisons. On average, patients who defaulted after moving received less than three-quarters of their recommended treatment regimens. These patients may remain infectious or become infectious again. Our findings highlight the importance of ensuring complete treatment for TB patients who move; failure to do so will adversely affect patient health and TB control, especially in many high-risk populations and settings.

Coccidioidomycosis results from inhaling spores of the fungus Coccidioides spp. in soil or airborne dust in endemic areas. We investigated an outbreak of coccidioidomycosis in a 12-person civilian construction crew that excavated soil during an underground pipe installation on Camp Roberts Military Base, California in October 2007. Ten (83.3%) workers developed symptoms of coccidioidomycosis; eight (66.7%) had serologically confirmed disease, seven had abnormal chest radiographs, and one developed disseminated infection; none used respiratory protection. A diagnosis of coccidioidomycosis in an eleventh worker followed his exposure to the outbreak site in 2008. Although episodic clusters of infections have occurred at Camp Roberts, the general area is not associated with the high disease rates found in California's San Joaquin Valley. Measures to minimize exposure to airborne spores during soil-disrupting activities should be taken before work begins in any coccidioides-endemic area, including regions with only historic evidence of disease activity.
