Schistosomiasis and strongyloidiasis cause substantial morbidity and mortality among hundreds of millions of infected persons worldwide. In the United States, these infections are most commonly found among international travelers, immigrants, and refugees from areas of endemicity. Refugees resettled to the United States since 2000 include >3800 "Lost Boys and Girls" of Sudan and 8000 Somali Bantu. Many Lost Boys and Girls of Sudan reported chronic abdominal pain only since arrival, and some received diagnoses of schistosomiasis or strongyloidiasis. We assessed seroprevalence of these infections among these refugees and hypothesized an association between infection and abdominal pain. ⋯ The high seroprevalence of schistosomiasis and strongyloidiasis among Sudanese Lost Boys and Girls and Somali Bantu refugees supports presumptive treatment for these refugees. Current refugee resettlement policies inadequately address these diseases; our data support consideration of predeparture presumptive therapy for all refugees from areas of endemicity.

Editorial Comment
Confronting Clostridium difficile in inpatient health care facilities.

Infective endocarditis is a potentially fatal consequence of illicit injection drug use. We estimate that the number of hospitalization for injection drug use-related infective endocarditis increased by 38%-66% in the United States between 2000-2001 and 2002-2003, a period during which the number of at-risk persons (i.e., injection drug users) remained stable. Increasing methamphetamine use and/or drug injection frequency may have increased the incidence of infective endocarditis among active injection drug users.

Prompted by the changing profile of Clostridium difficile infection and the impact of formulary policies in hospitals, we performed this study when an increase in the incidence of C. difficile-associated disease was noted at our health care center (Veterans Administration Puget Sound Health Care System, Seattle, Washington). ⋯ The increase in the number of cases of C. difficile-associated disease was not attributable to a formulary change of fluoroquinolones; instead, the incidence was within expected seasonal variations for C. difficile-associated disease. Recognition of community-acquired cases and the use of culture may help to identify additional cases of C. difficile-associated disease. Early diagnosis and treatment of C. difficile cases may shorten the duration of hospital stays and reduce the number of outbreaks and readmissions, mortality, and other consequences of C. difficile infection.

Multicenter Study
Patterns of resolution of chest radiograph abnormalities in adults hospitalized with severe community-acquired pneumonia.
Timing of follow-up chest radiographs for patients with severe community-acquired pneumonia (CAP) is difficult, because little is known about the time to resolution of chest radiograph abnormalities and its correlation with clinical findings. To provide recommendations for short-term, in-hospital chest radiograph follow-up, we studied the rate of resolution of chest radiograph abnormalities in relation to clinical cure, evaluated predictors for delayed resolution, and determined the influence of deterioration of radiographic findings during follow-up on prognosis. ⋯ Routine short-term follow-up chest radiographs (obtained <28 days after hospital admission) of hospitalized patients with severe CAP seem to provide no additional clinical value.
