Effectiveness of measures to eradicate Staphylococcus aureus carriage in patients with community-associated skin and soft-tissue infections: A randomized trial

BACKGROUND: Despite a paucity of evidence, decolonization measures are prescribed for outpatients with recurrent Staphylococcus aureus skin and soft tissue infections (SSTI). OBJECTIVE: Compare the effectiveness of four regimens for eradicating S. aureus carriage. DESIGN: Open-label, randomized controlled trial. Colonization status and recurrent SSTI were ascertained at one and four months. SETTING: Barnes-Jewish and St. Louis Children’s Hospitals, St. Louis, Missouri, 2007–2009. PARTICIPANTS: Three hundred patients with community-onset SSTI and S. aureus colonization in the nares, axilla, or inguinal folds. INTERVENTIONS: Participants were randomized to receive no therapeutic intervention (controls) or perform one of three 5-day regimens: 2% mupirocin ointment applied to the nares twice daily, intranasal mupirocin plus daily 4% chlorhexidine body washes, or intranasal mupirocin plus daily dilute bleach water baths. RESULTS: Among 244 participants with one-month colonization data, modified intention-to-treat analysis revealed S. aureus eradication in 38% of participants in the education only (control) group; 56% in the mupirocin group (p=0.03 vs. controls); 55% in the mupirocin/chlorhexidine group (p=0.05); and 63% in the mupirocin/bleach group (p=0.006). Of 229 participants with four-month colonization data, eradication rates were 48% in controls; 56% for mupirocin only (p=0.40 vs. controls); 54% for mupirocin/chlorhexidine (p=0.51); and 71% for mupirocin/bleach (p=0.02). At one and four months, respectively, recurrent SSTI was reported by 20% and 36% of participants. CONCLUSIONS: An inexpensive regimen of dilute bleach baths, intranasal mupirocin, and hygiene education effectively eradicated S. aureus over four months. High rates of recurrent SSTI suggest factors other than endogenous colonization as important determinants of infection

Association of prenatal exposure to maternal drinking and smoking with the risk of stillbirth.

Key points: Question: Is prenatal exposure to maternal drinking and smoking associated with the risk of stillbirth? Findings: In this cohort study of 8506 pregnant women (with 11 892 pregnancies) in Cape Town, South Africa, and the Northern Plains in the US, dual exposure to drinking and smoking after the first trimester of pregnancy had 2.78 times the risk of late stillbirth compared with those with no exposure or who had quit before the end of the first trimester of pregnancy. Meaning: These findings suggest that dual exposure to drinking and smoking after the first trimester of pregnancy is associated with nearly 3 times the risk of late stillbirth

Exploring the Manifestations of Anxiety in Children with Autism Spectrum Disorders

This study explores the manifestation and measurement of anxiety symptoms in 415 children with ASDs on a 20-item, parent-rated, DSM-IV referenced anxiety scale. In both high and low-functioning children (IQ above vs below 70), commonly endorsed items assessed restlessness, tension and sleep difficulties. Items requiring verbal expression of worry by the child were rarely endorsed. Higher anxiety was associated with functional language, IQ above 70 and higher scores on several other behavioral measures. Four underlying factors emerged: Generalized Anxiety, Separation Anxiety, Social Anxiety and Over-arousal. Our findings extend our understanding of anxiety across IQ in ASD and provide guidance for improving anxiety outcome measurement
