Helminth Eggs Detected in Soil Samples of a Possible Toilet Structure Found at the Capital Area of Ancient Baekje Kingdom of Korea

Although research conducted in East Asia has uncovered parasite eggs from ancient toilets or cesspits, data accumulated to date needs to be supplemented by more archaeoparasitological studies. We examined a total of 21 soil samples from a toilet-like structure at the Hwajisan site, a Baekje-period royal villa, in present-day Korea. At least 4 species of helminth eggs, i.e., Trichuris trichiura, Ascaris lumbricoides, Clonorchis sinensis, and Trichuris sp. (or Trichuris vulpis) were detected in 3 sediment samples of the structure that was likely a toilet used by Baekje nobles. The eggs of T. trichiura were found in all 3 samples (no. 1, 4, and 5); and A. lumbricoides eggs were detected in 2 samples (no. 4 and 5). C. sinensis and T. vulpis-like eggs were found in no. 5 sample. From the findings of this study, we can suppose that the soil-transmitted helminths were prevalent in ancient Korean people, including the nobles of Baekje Kingdom during the 5th to 7th century.

Survey About Handling Telephone Consultations at a Kampo Outpatient Clinic / 日本東洋医学雑誌

We conducted a fact­finding survey about the difficulties of handling the telephone consultations at a Kampo medicine outpatient clinic. We extracted the details of consultations that could not be handled by an outpatient nurse alone from the descriptive data of the telephone responses described by the nurses in the sur­vey. We, then, identified the factors that were involved in the difficulties encountered in these consultations, and countermeasures were established and implemented. One year later, we compared and examined the status of telephone consultations between before and after the fact-­finding survey. We classified the telephone con­sultations that were difficult for the outpatient nurses to handle alone into four categories : (1) consultation about a physical disorder, (2) questions about prescribed Kampo medicines, (3) reports and questions based on the patient's own judgment, and (4) questions about treatment and hospitalization. Some of the questions about Kampo medicines included the continued use of the medicine and drug interactions, and the main topics of the survey's nurse self-­judgment reports were dose reductions and changes in Kampo medicine regimens. As a re­sult of the introduction of guidelines prepared by the nurses together with physicians at the clinics, the outpa­tient nurses became able to handle telephone consultations about frequently asked questions (FAQs). At 1 year after the survey, the number of cases of difficulties in handling telephone consultations decreased to less than half the original value, and no telephone consultations were made within 1 week after the patients' first visits to the outpatient clinic.
