BackgroundEmergence of human fascioliasis prompted a worldwide control initiative including a pilot study in a few countries. Two hyperendemic areas were chosen: Huacullani, Northern Altiplano, Bolivia, representing the Altiplanic transmission pattern with high prevalences and intensities; Cajamarca valley, Peru, representing the valley pattern with high prevalences but low intensities. Coprological sample collection, transport and study procedures were analyzed to improve individual diagnosis and subsequent treatments and surveillance activities. Therefore, a coproantigen-detection technique (MM3-COPRO ELISA) was evaluated, using classical techniques for egg detection for comparison.Methodology and FindingsA total of 436 and 362 stool samples from schoolchildren of Huacullani and Cajamarca, respectively, were used. Positive samples from Huacullani were 24.77% using the MM3-COPRO technique, and 21.56% using Kato-Katz. Positive samples from Cajamarca were 11.05% using MM3-COPRO, and 5.24% using rapid sedimentation and Kato-Katz. In Huacullani, using Kato-Katz as gold standard, sensitivity and specificity were 94.68% and 98.48%, respectively, and using Kato-Katz and COPRO-ELISA test together, they were 95.68% and 100%. In Cajamarca, using rapid sedimentation and Kato-Katz together, results were 94.73% and 93.58%, and using rapid sedimentation, Kato-Katz and copro-ELISA together, they were 97.56% and 100%, respectively. There was no correlation between coproantigen detection by optical density (OD) and infection intensity by eggs per gram of feces (epg) in Cajamarca low burden cases (<400 epg), nor in Huacullani high burden cases (≥400 epg), although there was in Huacullani low burden cases (<400 epg). Six cases of egg emission appeared negative by MM3-COPRO, including one with a high egg count (1248 epg).ConclusionsThe coproantigen-detection test allows for high sensitivity and specificity, fast large mass screening capacity, detection in the chronic phase, early detection of treatment failure or reinfection in post-treated subjects, and usefulness in surveillance programs. However, this technique falls short when evaluating the fluke burden on its own.

Background Developmental disorders, including autism spectrum disorders (ASDs), are increasing in prevalence. Early identification is necessary for early intervention, which is critical for reducing challenges and lifetime costs, especially for ASDs. Because not all children have equal access to developmental and autism screening through primary care settings, nontraditional methods are needed to reach underserved populations. Purpose In this proof-of-concept study, the 2-1-1 Los Angeles County Developmental Screening Project (2-1-1 LA Project) provided developmental and autism screening by telephone in a population of low-income and racially and ethnically diverse children. Methods Aggregate data were reviewed for 2845 children who were screened for developmental delays using the Parents’ Evaluation of Developmental Status (PEDS) instrument and/or autism using the Modified Checklist for Autism in Toddlers (M-CHAT) instrument between September 1, 2009, and October 31, 2011. Results Data analysis was conducted December 2011 through February 2012. A majority of children (56%) screened with the PEDS had a moderate to high risk of developmental delays, including 28.2% classified as high-risk, which indicates need for further evaluation. Among 1605 children screened with the M-CHAT, 21.2% had an elevated risk of ASDs. Follow-up care coordination was provided for 2625 children to facilitate completion of referrals for diagnostic evaluation, early childhood education, and other developmental or behavioral needs. Conclusions The project’s approach enhanced access to screenings and referral uptake in a population of children that may have difficulty accessing primary care. Findings suggest the potential of nontraditional developmental screening models.

Since the advent of highly active antiretroviral therapy (HAART), the incidence of opportunistic infections (OI) in patients with HIV has markedly decreased. Despite this, there are still large numbers of Pneumocystis carinii pneumonia (PCP) cases at Cook County Hospital (CCH). To better understand this patient group, we performed a retrospective chart review of 120 pathologically proven cases of PCP from January 1998 to June 2001. One hundred four patients were included in the study. Sixty-nine percent of our patients were active substance abusers and 50% had previous knowledge of HIV disease. Of our patients, fewer than 5% were on HAART or PCP prophylaxis on study admission. The overall mortality rate was 14%. Of discharged patients, 65% were placed on HAART therapy and 59% of these achieved a viral load of less than 1000 copies per milliliter in the year postdischarge. Patients who failed to achieve a viral load less than 1000 copies per milliliter were more likely active substance abusers or had a viral load greater than 100,000 copies per milliliter prior to study admission. Our study shows that patients are still being admitted with PCP in the HAART era. Active substance abuse and failure to recognize HIV status contributed heavily to this late presentation of HIV disease. An aggressive approach toward HIV identification and substance abuse treatment may decrease admissions to the hospital for PCP and improve response to HAART therapy.
