Depleted uranium particles in selected Kosovo samples.

Selected soil samples, collected in Kosovo locations where DU ammunition was expended during the 1999 Balkan conflict, have been investigated by secondary ion mass spectrometry (SIMS), X-ray fluorescence imaging using a micro-beam (micro-XRF) and scanning electron microscopy equipped with an energy dispersive X-ray fluorescence detector (SEM-EDXRF), with the objective to test the suitability of these techniques to identify the presence of small DU particles and measure their size distribution and the 235U/238U isotopic ratio (SIMS). Although the results do not permit any legitimate extrapolation to all the sites hit by the DU rounds used during the conflict, they indicated that there can be "spots ' where hundreds of thousands of particles may be present in a few milligrams of DU contaminated soil. The particle size distribution showed that most of the DU particles were <5 microm in diameter and more than 50% of the particles had a diameter <1.5 microm. Knowledge on DU particles is needed as a basis for the assessment of the potential environmental and health impacts of military use of DU, since it provides information on possible re-suspension and inhalation.

Staphylococcal scalded skin syndrome in a woman with chronic renal failure exposed to human immunodeficiency virus.

A twenty-eight-year-old woman seropositive for the human immunodeficiency virus and undergoing hemodialysis for end-stage renal disease sustained an infection of her arteriovenous graft. Multiple erythematous erosions appeared and a diagnosis of staphylococcal scalded skin syndrome was made when a frozen section of a fresh skin peel revealed an intraepidermal split through the granular layer and Staphylococcus aureus group II, phage type 71 was cultured from the wound and blood. Twenty-six cases of adult patients with staphylococcal scalded skin syndrome have been reported. Although this includes one patient with AIDS-related complex, this is the first case of an adult with staphylococcal scalded skin syndrome who showed seropositive results of testing for human immunodeficiency virus.

Evaluation of mandibular infiltration versus block anesthesia in pediatric dentistry.

The authors consider mandibular infiltration as a possible alternative to mandibular block anesthesia in young children. The study sample comprised eighteen children ages six to nine years old who required bilateral identical treatment on primary mandibular molars. A random number table was used to determine which side of the mouth was to receive the block or the infiltration technique and a coin toss determined which would be administered first: A short 27 gauge needle was used to inject a 2 percent lidocaine solution with 1:100,000 epinephrine, in both techniques. The paired t-test indicated no significant difference between the two techniques for any of the factors evaluated.
