DRAMATIC DROP IN HIV INFECTIONS HALTS CIRCUMCISION TRIALS

According to two randomized control trials conducted in Kenya and Uganda with NIH support, men who are circumcised have approximately half the risk of uncircumcised men of contracting HIV through vaginal intercourse. The risk reduction was 48% in Uganda and 53% in Kenya, replicating results found in a similar, previous study in South Africa that showed a 60% decreased risk of HIV by female to (circumcised) male. All three trials enrolled adult males desiring circumcision, and all participants received education regarding condom use and safer sexual practices.

Anthony Fauci, director of NIAID at NIH called adult male circumcision an “important addition to an HIV prevention strategy for men.” The WHO has developed activities regarding male circumcision and offers guidance and training to countries that desire to make the procedure a more prominent part of their HIV prevention strategies.

AN APPROACH TO PREVENTION OF INFECTIOUS DISEASES DURING MILITARY DEPLOYMENTS

The approach to prevention of infectious diseases utilized by the US military during deployments has elements that are applicable to disaster relief and humanitarian missions in the civilian sector. The six part method involves preparation, education, personal protective measures, vaccines, chemoprophylaxis and surveillance.

Preparation entails familiarity with the most likely infectious etiologies in a location, preparation/supplies for managing acute infections, and infection control strategies that are appropriate for the location. Education of those deploying and those responsible for their medical is also critical – and is the basis for good preparation. Utilization of standard precautions against infection and injury plus avoidance of vector exposure and contaminated water are personal protective measures. The military regularly administers routine and deployment-specific vaccines and requires hepatitis B vaccination by all personnel. Chemoprophylaxis regimens for malaria follow CDC guidelines, and the military is exploring other agents, as appropriate to specific settings. Surveillance is critical to ongoing assessment of military infectious disease prevention strategies; they utilize tracking systems for key infectious diseases, and all personnel undergo pre- and post-deployment medical evaluations.

The authors describe ways in which this six-part approach has applicability in civilian disaster response and humanitarian missions.

PREVENTION OF ROTAVIRUS DISEASE: GUIDELINES FOR USE OF ROTAVIRUS VACCINE

The American Academy of Pediatrics is recommending oral administration of the new rotavirus vaccine to infants at 2, 4, and 6 months of age. The bovine-based pentavalent vaccine was approved by the FDA on February 3, 2006. The four-part rational for this recommendation is described in their policy statement. First, similar rates of rotavirus infection among children in developed and developing nations indicate that clean water and good hygiene have little impact on transmission. Then, they note the on-going morbidity associated with rotavirus in the US, despite other currently available therapies. Third, studies of the natural progression of the disease suggest that initial infection protects children against future gastroenteritis. Finally, US vaccine trials have demonstrated 98% efficacy for prevention of severe illness from rotavirus and 74% efficacy for prevention against viral diarrhea of any severity. Vaccine adverse events, contraindications and precautions are also discussed.

A COMPREHENSIVE IMMUNIZATION STRATEGY TO ELIMINATE TRANSMISSION OF HEPATITIS B VIRUS INFECTION IN THE UNITED STATES

ACIP has published updated recommendations to increase hepatitis B vaccination of adults at risk for HVB infection. The primary changes from previous recommendations include: universal hepatitis B vaccination for all adults in setting in which a large proportion of the population are likely to be at risk for HBV infection; implementation in of standing orders in medical settings to identify and vaccinate adults recommended for vaccination; provision of information describing the health benefits, risk factors, and suggested groups of vaccine recipients, risk assessment  to inform appropriateness of vaccination on a patient-specific basis and vaccination to all adults who report risks for HBV infection or request vaccination to ensure vaccination of adults at risk who have not completed the vaccination series. The MMWR report also describes HBV infection, populations at risk for infection, vaccine schedules, and safety of the hepatitis B vaccine.

SUNSAFE IN THE MIDDLE SCHOOL YEARS: A COMMUNITY-WIDE INTERVENTION TO CHANGE EARLY-ADOLESCENT SUN PROTECTION

Rates of skin cancer associated with early-life sun exposure are rising, and sun protection rapidly declines during the adolescent years. The SunSafe in the Middle School Years program is a multi-component model to improve adolescent sun protection behaviors. Annual educational sessions for adults (clinicians, school personnel, athletic coaches and pool/beach staff) and staff and peer-led activities for middle school students were complemented by sun protection promotion materials distributed in the community (bookmarks, posters). Sun behaviors were observed and the proportion of the individual adolescents’ body surface protected from the sun was measured. The randomized controlled trial conducted in ten communities demonstrated a significant intervention effect after two years. This ecological approach appears to be an effective way to positively impact adolescent sun behaviors and potentially reduce their risk of skin cancer.

OFFICE-BASED COUNSELING FOR UNINTENTIONAL INJURY PREVENTION

A recent report provides guidance to pediatricians regarding injury-prevention counseling at various developmental stages. Parents of infants should be counseled about traffic safety, burn, fall, choking and drowning prevention, creating a safe sleep environment and CPR. Parents of preschool aged children should be advised regarding traffic safety, burn, fall, poison and drowning prevention, and firearm safety. Counseling of parents and their school-aged children should concentrate on traffic, water, sports, and firearm safety. Adolescents should receive guidance on traffic, water, sports and firearm safety. Specific recommendations and suggestions for implementation are included in the report.

BRIEF INTERVENTION FOR ALCOHOL USE BY PREGNANT WOMEN

Brief intervention is an effective method to help pregnant women abstain from alcohol. A study in which hundred fifty-five pregnant women who reported using alcohol received either assessment-only or brief intervention demonstrated that women in the intervention group were five times more likely to report abstinence than women in the assessment-only group. In addition, newborns of mothers in the intervention group had higher birth lengths and birth weights, and their fetal mortality rate was three times lower than newborns of women who received assessment-only. The brief intervention was provided by nonmedical professionals (WIC nutritionists) at WIC centers, demonstrating that non-physician providers and community-based organizations can play a critical role in reducing alcohol consumption during pregnancy and improving newborn outcomes.
