We examined stool specimens of the residents in the emigration camp in Tijuana, Mexico for helminth eggs or protozoan cysts with formalin-ethyl acetate concentration method in February and July 1992. Out of 92 examined samples, number of positive was 49 (53.3%). While number of cumulative positive was 66 (71.7%). Cysts of Entamoeba coli (29.3%) Giardia lamblia (9.8%), Entamoeba histolytica (7.6%), and eggs of Taenia spp. (6.5) were most frequently observed. Filtered water supply and chemotherapy were required in this camp.

Clinical analysis of 170 patients with childhood leukemia was made, who were admitted to the department of Pediatrics, Pusan Paik Hospital, Inje University, College of Medicine during 10 years from 1981 to 1990. The results were as follows: 1) The annual number of the patients with childhood leukemia was in the range of 6~25 cases. And the annual rate of the number of the patients in the department of the Pediatrics was 0.37~1.60% with the average of 1.06%. 2) Of the 170 patients, 72 cases(42.3%) were in the range of 0~5 years of age, which was the largest age group. In male, of the 97 patients, the largest age group was the age group of 0~5 years, which included 45 cases (46.4%), while in female, the largest was that of 6~10 years, which included 29 cases of 73 patients (39.8%). 3) Of the 170 patients, sex ratio was 1.33:1 with male dominance in all age groups except 1:1.6 with female dominance in the age group of 6~10 years. 4) Of the 170 patients, 113 cases were ALL (66.5%), 50 cases AML (29.4%), and 7 cases CML (4.1%). 5) In ALL, 51 cases of the 113 patients (45.1%), were in the age group of 0~5 years, 35 cases (31%) in the age group of 6~10 years, and 27 cases (23.9%) in the age group of 11~15 years.

With 2mm-thick CT scanning during the rapid infusion of contrast material(TICT), cerebral aneurysms arising from the circle of Willis and adjacent vessels can be directly visualized. Twenty-five patients who had cerebral aneurysm confirmed by surgery were examined with TIGT and digital subtraction angiography. The authors examined TIGT prospectively to assess the detection rate of the cerebal aneurysms and to evaluate the clinical usefulness of TIGT. The detection rates of aneurysms by TIGT and digital subtraction angiography were 68% and 84%, respectively. TIGT is a rapid, safe and reliable method in the evaluation of patients with suspected cerebral aneurysm, permitting direct visualization of the aneurysm.

Arteriovenous mafformation(AVM) of female pelvic organ is a rare disease of unknown cause. The authors' report a case of pelvic AVM which was incidentally found during US examination of the patient with choriocarcinoma after chemotherapy. The real-time sonography revealed several cystic lesions around the uterus with adjacent dilated tortuous vessels. The color Doppler sonography depicted abundant blood flow mixed with red and blue colors within the cystic lesions and rapid turbulent systolic and diastolic flows. CT showed well-enhancing round vascular lesions with elongated vessels in the pelvis, and MRI depicted signal-void cystic lesions on both T1 and T2 weighted images with small portions of high intensity within the lesions on T2 weighted image. The angiography revealed pelvic AVM fed by tortuous uterine and vaginal arteries with a dilated draining vein

203Hg neohydrin renal scanning was done in 32 cases of various renal diseases to evaluate its diagnostic significance by comparing with I.V.P. and with the weight of renal parenchyme remained in post-nephrectomized specimens. 1. The incidence depicting warm area on renal scanning was higher than that of excretory findings on I.V.P.; approximately one third of non-visualizing kidneys on pyelogram showed positive renal images by renal scanning. 2. The size of warm area on renal scanning closely correlated with the weight of parenchyme remained in diseased kidney. 3. The technique of renal scanning was more simple and less hazardous than that of I.V.P. 4. Renal scanning would be so valuable in the diagnosis of renal diseases, particularly for advanced lesions and that the combination of renal scanning and I.V.P. was desirable

We compared the DNA sequences of the genus Metagonimus: M. yokogawai, M. takahashii, and M. miyatai. We obtained 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome c oxidase subunit I (mtCOI) fragments from the adult worms by PCR, that were cloned and sequenced. Phylogenetic relationships inferred from the nucleotide sequences of the 28S D1 rDNA and mtCOI gene. M. takahashii and M. yokogawai are placed in the same clade supported by DNA sequence and phylogenic tree analysis in 28S D1 rDNA and mtCOI gene region. The above findings tell us that M. takahashii is closer to M. yokogawai than to M. miyatai genetically. This phylogenetic data also support the nomination of M. miyatai as a separate species.

This case report demonstrates an unnecessary endodontic treatment of teeth with florid cemento-osseous dysplasia (FCOD) due to a misdiagnosis as periapical pathosis and emphasizes the importance of correct diagnosis to avoid unnecessary treatment. A 30-year-old woman was referred to our institution for apicoectomies of the mandibular left canine and both the lateral incisors. The periapical lesions associated with these teeth had failed to resolve after root canal treatment over a 3-year period. Radiographic examinations revealed multiple lesions on the right canine, the second premolar, and both first molars as well as the anterior region of the mandible. Based on clinical, radiographic and histological evaluations, the patient condition was diagnosed as FCOD. The patient has been monitored for 2 years. To avoid unnecessary invasive treatment, accurate diagnosis is essential before treatment is carried out in managing FCOD.

Primary peptic ulcer disease in not known to be the result of underlying illness or trauma. These are most frequently duodenal or prepyloric. Since clinical features of peptic ulcer in children can easily be confused with many other disorders, the diagnosis is usually made when one of the more dramatic presentations, such as perforation, bleeding and obstruction. Recently, we experienced 2 cases of duodenal obstruction due to peptic ulcer in children. So, we report it with review of references.
