Prevention of measles spread on a paediatric ward.

Since measles is a highly contagious respiratory infection with significant airborne transmission risk in hospitals, effective prevention measures are crucial. After a mother accompanying her child on a paediatric ward lacking a negative pressure room was diagnosed with measles, exposed persons without evidence of immunity (documentary evidence of receiving two doses of measles-mumps-rubella vaccine) were treated with vaccination or intravenous immunoglobulin (IVIG). The interruption of transmission with these treatments was evaluated. There were 44 children and 101 adults exposed to the index patient. Twenty-five children and 88 adults were considered immune, providing evidence of immunity. Nineteen children and 13 adults were either given vaccination or IVIG for post-exposure prophylaxis (PEP). There were no additional cases of measles after 3 weeks follow-up. We conclude that measles is highly preventable by adequate PEP with vaccination or IVIG in a healthcare setting that lacks the benefit of a negative pressure room.

Epstein-barr virus encephalitis in infancy.

Epstein-Barr virus (EBV) infection causes a wide spectrum of illness in humans including subclinical infection, infectious mononucleosis, and is associated with some malignancies. This report presents the clinical findings of an unusual case of EBV encephalitis in a 10-month old infant who presented with a febrile infection and seizures. The clinical manifestations, serologic study and a dynamic change of EBV DNA in cerebrospinal fluid with spontaneous recovery confirmed the diagnosis of EBV infection of the nervous system.

Hydrocortisone acetate alone or combined with mupirocin for atopic dermatitis in infants under two years of age - a randomized double blind pilot trial.

BACKGROUND: The skin of patients with atopic dermatitis (AD) is heavily colonized with Staphylococcus (S.) aureus, even at uninvolved sites. Toxins secreted by the majority of S. aureus on the skin behave as superantigens and can directly influence the disease activity, although clinical signs of bacterial superinfection might be absent. OBJECTIVES: This study was conducted to compare the efficacy of hydrocortisone cream, combined with mupirocin or alone with emmolient ointment for the treatment of mild to moderate AD in infants between six months and two years of age. MATERIALS AND METHODS: A total of 83 patients with mild to moderate AD were randomized to receive hydrocortisone, hydrocortisone+ mupirocin or emmolient ointment twice daily in one week and followed-up for 8 weeks, in a blind study. Efficacy evaluation made by SCORAD and eczema area and severity index (EASI) at baseline, day 7, and weeks 2, 4, and 8. Possible adverse events were recorded to evaluate safety. RESULTS: At the end of study, 65% (17 of 26) of the patients were treated successfully with hydrocortisone ointment based on SCORAD and EASI scores. Also there was a significant improvement in patients combined with mupirocin ointment [74% (20 of 27)]. The percent improvement from baseline in EASI scores was also significantly greater in hydrocortisone and combined group compared with emmolient-treated patients (36%) (p = 0.0187, p = 0.012 respectively). CONCLUSIONS: Monotherapy with hydrocortisone ointment is the main treatment in infants with mild to moderate AD and combination with mupirocin is safe and effective often needed because of possible Staphylococcus carriage.

Serosurveillance study on transmission of H5N1 virus during a 2006 avian influenza epidemic.

In 2006 an outbreak of avian influenza A(H5N1) in Turkey caused 12 human infections, including four deaths. We conducted a serological survey to determine the extent of subclinical infection caused by the outbreak. Single serum samples were collected from five individuals with avian influenza whose nasopharyngeal swabs tested positive for H5 RNA by polymerase chain reaction, 28 family contacts of the cases, 95 poultry cullers, 75 individuals known to have had contact with diseased chickens and 81 individuals living in the region with no known contact with infected chickens and/or patients. Paired serum samples were collected from 97 healthcare workers. All sera were tested for the presence of neutralizing antibodies by enzyme-linked immunoassay, haemagglutination inhibition and microneutralization assays. Only one serum sample, from a parent of an avian influenza patient, tested positive for H5N1 by microneutralization assay. This survey shows that there was minimal subclinical H5N1 infection among contacts of human cases and infected poultry in Turkey in 2006. Further, the low rate of subclinical infection following contact with diseased poultry gave further support to the reported low infectivity of the virus.
