Two cases of human Echinostoma hortense infection were found in Seoul Paik Hospital. Their stools revealed echinostomatid eggs. After treatment with praziquantel (single does of 10-12 mg/kg) and purgation with magnesium salt, total 21 flukes were collected in one case. The flukes were 5.9-7.5 mm long, had 27-28 collar spines around their head, laterally deviated ovary and two tandem testes. They were identified as E. hortense Asada, 1926. The cases are 38-year and 20-year old men residing in Seoul, whose hometown is Chungsong-gun and Seungju-gun, Kyongsangbuk-do respectively. They had eaten raw flesh of various kinds of fresh water fishes (both cases) and/or salamander (latter case), which are considered possible sources of this fluke infection. They experienced abdominal discomfort and/or diarrhea. Hematology revealed 22 percent eosinophilia in the latter case, but it became 5 percent after the treatment. Echinostomatid eggs were not found after the treatment in both cases. These are the 4th and 5th human cases of E. hortense infection in Korea.

Asymmetrical Septal Hypertrophy(ASH), Characterized by interventricular septal hypertrophy, is not an uncommon cardiac disease. Arrythmia occuring in ASH are supraventricular tachycardia, atrial premature beats, and ventricular premature beats. In about 10% of patients, there is a short P-R interval and a partial delta wave, suggestive of a variant of the Wolff-Parkinson-White syndrome. We reported here a case of ASH associated with W-P-W syndrome and paroxysmal atrial fibrillation with review of pertinent literatures.

A human case of Echinostoma cinetorchis infection was found in Seoul Paik Hospital on August 1987. Large trematode eggs, 98.9 x 62.7 micro-m in average size, were detected in stool examination. The eggs had a small-sized operculum and abopercular wrinkling. After treatment with praziquantel(single dose of 16.2 mg/kg) and purgation with magnesium citrate, an adult fluke was collected. It was 8.0 mm long, equipped with 37 collar spines around head crown, and had only one testis just behind the Mehlis' gland. It was identified as E. cinetorchis Ando et Ozaki, 1923. The patient is an 18-year old man residing in Seoul, and was hospitalized due to nephritis. He had eaten raw meat juice of fresh water fishes such as top minnows(Oryzias latipes) and loaches, or tadpoles, which are considered possible souce of this fluke infection. This is the 4th human case of E. cinetorchis infection in Korea.
