RESUMO
A total of 107 sandpits in public parks in Sapporo City were examined, 9 and 73 were contaminated with helminth eggs and fecal coliforms, respectively. Of the nine in which eggs were detected, eight were contaminated with Toxocara spp. and one with Capillaria spp. eggs. The contamination rate of sandpits of more than 30 m2 ranged from 43 to 50%, while in those 30 m2 or less it was between 73 and 92%. Although helminth eggs were evenly distributed throughout all layers of the sandpits, fecal coliforms were localized on the sandpit surfaces. Recovered Toxocara eggs were identified according to their size and surface structures, and almost all eggs were T. cati. Based on these results, and given the inherent habits of cats, measures to prevent their defecation in sandpits are needed, especially ones of smaller size.

We evaluated the utility of in-situ hybridization (ISH) for the rapid diagnosis of sepsis. We applied this approach to polymorphonuclear neutrophil (PMN)-rich smears from patients with suspected bacterial infection. Positive results by ISH were obtained in the smears of 123 of 292 patients (42%), while only 32 of the 292 (11%) were positive by blood culture. These findings indicate that ISH is almost four times more sensitive than the culture method for the detection of sepsis. ISH results are obtained within 1 day, while 1 day to 2 weeks is required for the results of blood culture. Blood culture and ISH methods detected the same bacteria in two patients. ISH also successfully identified the same bacteria in blood and PMN-rich body fluid (bronchoalveolar lavage samples) in 6 patients. In 19 patients, ISH of blood detected the same bacteria as those found in subcultures from other sources (e.g., stool, sputum, nasal cavity). We discuss these results in comparison with blood culture results in terms of evaluating a rapid approach to the management of patients with sepsis.
