Haplosporidiosis of the Pacific oyster, Crassostrea gigas.

Haplosporidan parasites were observed in 10/100 spat and 1/171 adult Pacific oysters, Crassostrea gigas, reared in Matsushima Bay, Japan. Eight of the infected spat contained mild to severe plasmodial infections. The multinucleated plasmodia were 6-12 microm x 7-15 microm and were associated with an infiltration of hemocytes that occurred throughout the vesicular connective tissues of all infected oysters. Two oysters, one adult and one spat, contained advanced sporogonic infections. These were characterized by the presence of sporocysts and immature and mature operculated spores that measured 5.6-6.0 microm x 6.0-8.0 microm and were found exclusively within the digestive tubule epithelium. Electron microscopic examination revealed that mature spores contained a hinge operculum, striated and layered wall, spherule, single nucleus, and haplosporosome formative regions. Parasite morphology and infection pattern closely resemble that of Haplosporidium nelsoni, a pathogen of American oysters (C. virginica).

Use of articaine local anesthesia in children under 4 years of age--a retrospective report.

A retrospective survey reports the use of articaine hydrochloride as an anesthetic in children under 4 years of age. Data was collected by a record audit in two pediatric dentistry offices. Articaine anesthetic was administered to 211 patients, 29 having additional administrations of the agent. In some instances, the dosages exceeded the recommended concentrations for older children. No adverse systemic adverse reactions were noted on the charts or known to the clinicians. The present report provides initial evidence for the use of articaine in children under 4 years of age.
