The Solution Is a Solution.

BACKGROUND: Infections in neonates with herpes simplex virus 1 (HSV-1) following circumcision due to Metzitzah Be'Peh (MBP) performed by a Mohel occur each year in small numbers. One solution to this problem is the use of a mucus extractor device instead of MBP, which has been authorized by some rabbis. Yet, using a mucus extractor remains controversial among ultra-Orthodox Jews; thus, creating a need for additional solutions. OBJECTIVES: To seek to reduce HSV-1 infection of neonates due to MBP. METHODS: We tested several oral rinse solutions for their ability to destroy virus infectivity following incubation for 30 seconds and using plaque reduction assays. RESULTS: Corsodyl, Decapinol, and Listerine® all destroyed plaques formation of spiked virus, while Gengigel and Tantum Verde were found to be less effective. We focused specifically on Listerine® due to its efficacy in eliminating contagious HSV-1 from saliva after a 30-second oral rinse. Five different products of Listerine® reduced the infectivity of a spiked virus by more than 4 orders of magnitude in 30 seconds. We also showed that Listerine (up to 7% v/v) can stay in the mouth but did not harm living cells and therefore will not cause any damage to the injured tissue. CONCLUSIONS: Significant reduction in cases of infection with HSV-1 due to MBP can be achieved if Mohalim consistently adopt the practice of careful mouth washing with Listerine® just before performing MBP.

Primary infection with human herpes virus type 6, post-pediatric liver transplantation-A pathogen to remember.

BACKGROUND: In recent years, liver transplantation (LT) has become a well-accepted therapeutic modality for children with end-stage liver disease, with transplantation surgery being performed at a younger age. Human herpes virus 6 (HHV-6) infection occurs in most children within the first 2 years of life, therefore, data on primary HHV-6 infection in pediatric liver transplant recipients is scarce. OBJECTIVE: To describe the course of primary HHV-6 infection after pediatric LT. METHODS: Medical files, between the years 2015-2016, of post-LT pediatric patients with suspected primary HHV-6 infection were reviewed. Clinical and laboratory data for enrolled cases were evaluated. Primary infection was defined as DNAemia in children who were seronegative prior to transplantation or seroconversion from negative to positive IgG posttransplantation. RESULTS: Four cases of primary HHV-6 (type B) infection were identified among the 26 children who had undergone LT at our center during the study period. All patients were <1 year old and presented with fever, hepatitis, and elevated inflammatory markers, most (75%) within a short-period posttransplantation. All were initially treated with empiric antibiotics for a suspected bacterial infection and three underwent liver biopsy, one showing signs of rejection. Three were treated with antiviral therapy with a gradual resolution of symptoms. DISCUSSION: Primary HHV-6 should be taken into account in young children shortly after LT, especially when presenting with fever and elevated liver enzymes. Treatment with antiviral therapy should be considered. CONCLUSIONS: In young infants post-LT, a high index of suspicion may promote early detection of HHV-6 primary infection and prevent serious complications.
