Am J Trop Med Hyg 2017 97 (4) 1170-1179 Since 2010, the World Health Organization has been recommending that all suspected cases of malaria be confirmed with parasite-based diagnosis before treatment. These guidelines represent a paradigm shift away from presumptive antimalarial treatment of fever. Malaria rapid diagnostic tests (mRDTs) are central to implementing this policy, intended to target artemisinin-based combination therapies (ACT) to patients with confirmed malaria and to improve management of patients with nonmalarial fevers. The ACT Consortium conducted ten linked studies, eight in sub-Saharan Africa and two in Afghanistan, to evaluate the impact of mRDT introduction on case management across settings that vary in malaria endemicity and healthcare provider type. This synthesis includes 562,368 outpatient encounters (study size range 2,400-432,513). mRDTs were associated with significantly lower ACT prescription (range 8-69% versus 20-100%). Prescribing did not always adhere to malaria test results; in several settings, ACTs were prescribed to more than 30% of test-negative patients or to fewer than 80% of test-positive patients. Either an antimalarial or an antibiotic was prescribed for more than 75% of patients across most settings; lower antimalarial prescription for malaria test-negative patients was partly offset by higher antibiotic prescription. Symptomatic management with antipyretics alone was prescribed for fewer than 25% of patients across all scenarios. In community health worker and private retailer settings, mRDTs increased referral of patients to other providers. This synthesis provides an overview of shifts in case management that may be expected with mRDT introduction and highlights areas of focus to improve design and implementation of future case management programs. |

BMJ 2017 356 j1054 Objectives To examine the impact of use of rapid diagnostic tests for malaria on prescribing of antimicrobials, specifically antibiotics, for acute febrile illness in Africa and Asia.Design Analysisof nine preselected linked and codesigned observational and randomised studies (eight cluster or individually randomised trials and one observational study).Setting Public and private healthcare settings, 2007-13, in Afghanistan, Cameroon, Ghana, Nigeria, Tanzania, and Uganda.Participants 522 480 children and adults with acute febrile illness.Interventions Rapid diagnostic tests for malaria.Main outcome measures Proportions of patients for whom an antibiotic was prescribed in trial groups who had undergone rapid diagnostic testing compared with controls and in patients with negative test results compared with patients with positive results. A secondary aim compared classes of antibiotics prescribed in different settings.Results Antibiotics were prescribed to 127 052/238 797 (53%) patients in control groups and 167 714/283 683 (59%) patients in intervention groups. Antibiotics were prescribed to 40% (35 505/89 719) of patients with a positive test result for malaria and to 69% (39 400/57 080) of those with a negative result. All but one study showed a trend toward more antibiotic prescribing in groups who underwent rapid diagnostic tests. Random effects meta-analysis of the trials showed that the overall risk of antibiotic prescription was 21% higher (95% confidence interval 7% to 36%) in intervention settings. In most intervention settings, patients with negative test results received more antibiotic prescriptions than patients with positive results for all the most commonly used classes: penicillins, trimethoprim-sulfamethoxazole (one exception), tetracyclines, and metronidazole.Conclusions Introduction of rapid diagnostic tests for malaria to reduce unnecessary use of antimalarials-a beneficial public health outcome-could drive up untargeted use of antibiotics. That 69% of patients were prescribed antibiotics when test results were negative probably represents overprescription.This included antibiotics from several classes, including those like metronidazole that are seldom appropriate for febrile illness, across varied clinical, health system, and epidemiological settings. It is often assumed that better disease specific diagnostics will reduce antimicrobial overuse, but they might simply shift it from one antimicrobial class to another. Current global implementation of malaria testing might increase untargeted antibiotic use and must be examined. |

Pediatrics 2012 130 (4) 768-773 Inguinal hernia repair in infants is a routine surgical procedure. However, numerous issues, including timing of the repair, the need to explore the contralateral groin, use of laparoscopy, and anesthetic approach, remain unsettled. Given the lack of compelling data, consideration should be given to large, prospective, randomized controlled trials to determine best practices for the management of inguinal hernias in infants.

Pediatrics 2012 130 (3) 587-597 Provision of risk-appropriate care for newborn infants and mothers was first proposed in 1976. This updated policy statement provides a review of data supporting evidence for a tiered provision of care and reaffirms the need for uniform, nationally applicable definitions and consistent standards of service for public health to improve neonatal outcomes. Facilities that provide hospital care for newborn infants should be classified on the basis of functional capabilities, and these facilities should be organized within a regionalized system of perinatal care.

Environ Health Perspect 2012 120 (10) 1450-5 BACKGROUND: During May-June 2010, a childhood lead poisoning outbreak related to gold-ore-processing was confirmed in 2 villages in Zamfara State, Nigeria. During June-September, villages with suspected or confirmed childhood lead poisoning continued to be identified in Zamfara State. OBJECTIVES: We investigated the extent of childhood lead poisoning (≥1 child with a blood lead level [BLL] ≥10 microg/dL) and lead contamination (≥1 soil/dust sample with a lead level >400 parts per million) among villages in Zamfara State and identified villages that should be prioritized for urgent interventions. METHODS: We used chain-referral sampling to identify villages of interest, defined as villages suspected of participation in gold-ore-processing during the previous 12 months. We interviewed villagers, determined BLLs among children aged <5 years, and analyzed soil/dust from public areas and homes for lead. RESULTS: We identified 131 villages of interest and visited 74 (56%) villages in 3 local government areas. Fifty-four (77%) of 70 villages that completed the survey reported gold-ore-processing. Ore-processing villages were more likely to have ≥1 child aged <5 years with lead poisoning (68% vs. 50%, p=0.17) or death following convulsions (74% vs. 44%, p=0.02). Soil/dust contamination and BLL ≥45 microg/dL were identified in ore-processing villages only [50% (p<0.001) and 15% (p=0.22), respectively]. The odds of childhood lead poisoning or lead contamination was 3.5 times as high in ore-processing villages than the other villages (95% CI: 1.1, 11.3). CONCLUSION: Childhood lead poisoning and lead contamination were widespread in surveyed areas, particularly among villages that had processed ore recently. Urgent interventions are required to reduce lead exposure, morbidity, and mortality in affected communities. |

Pediatrics 2012 129 (4) e1104-e1109 Health care-associated infections in the NICU are a major clinical problem resulting in increased morbidity and mortality, prolonged length of hospital stays, and increased medical costs. Neonates are at high risk for health care-associated infections because of impaired host defense mechanisms, limited amounts of protective endogenous flora on skin and mucosal surfaces at time of birth, reduced barrier function of neonatal skin, the use of invasive procedures and devices, and frequent exposure to broad-spectrum antibiotics. This statement will review the epidemiology and diagnosis of health care-associated infections in newborn infants. (Copyright 2012 by the American Academy of Pediatrics.) |
Lead poisoning in United States-bound refugee children: Thailand-Burma border, 2009
Mitchell T , Jentes E , Ortega L , Scalia Sucosky M , Jefferies T , Bajcevic P , Parr V , Jones W , Brown MJ , Painter J . Pediatrics 2012 129 (2) e392-9 BACKGROUND: Elevated blood lead levels lead to permanent neurocognitive sequelae in children. Resettled refugee children in the United States are considered at high risk for elevated blood lead levels, but the prevalence of and risk factors for elevated blood lead levels before resettlement have not been described. METHODS: Blood samples from children aged 6 months to 14 years from refugee camps in Thailand were tested for lead and hemoglobin. Sixty-seven children with elevated blood lead levels (venous ≥10 microg/dL) or undetectable (capillary <3.3 microg/dL) blood lead levels participated in a case-control study. RESULTS: Of 642 children tested, 33 (5.1%) had elevated blood lead levels. Children aged <2 years had the highest prevalence (14.5%). Among children aged <2 years included in a case-control study, elevated blood lead levels risk factors included hemoglobin <10 g/dL, exposure to car batteries, and taking traditional medicines. CONCLUSIONS: The prevalence of elevated blood lead levels among tested US-bound Burmese refugee children was higher than the current US prevalence, and was especially high among children <2 years old. Refugee children may arrive in the United States with elevated blood lead levels. A population-specific understanding of preexisting lead exposures can enhance postarrival lead-poisoning prevention efforts, based on Centers for Disease Control and Prevention recommendations for resettled refugee children, and can lead to remediation efforts overseas. |
Lead poisoning among Burmese refugee children--Indiana, 2009
Ritchey MD , Sucosky MS , Jefferies T , McCormick D , Hesting A , Blanton C , Duwve J , Bruner R , Daley WR , Jarrett J , Brown MJ . Clin Pediatr (Phila) 2011 50 (7) 648-56 Recent routine screening revealed multiple cases of unexplained lead poisoning among children of Burmese refugees living in Fort Wayne, Indiana. A cross-sectional study was conducted to determine (a) the prevalence of elevated blood lead levels (BLLs) among Burmese children and (b) potential sources of lead exposure. A case was defined as an elevated venous BLL (≥10 mug/dL); prevalence was compared with all Indiana children screened during 2008. Environmental and product samples were tested for lead. In all, 14 of 197 (7.1%) children had elevated BLLs (prevalence ratio: 10.7) that ranged from 10.2 to 29.0 mug/dL. Six cases were newly identified; 4 were among US-born children. Laboratory testing identified a traditional ethnic digestive remedy, Daw Tway, containing a median 520 ppm lead. A multilevel linear regression model identified daily use of thanakha, an ethnic cosmetic, and Daw Tway use were related to elevated BLLs (P < .05). Routine monitoring of BLLs among this population should remain a priority. |
