An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine checkup on a 34 year-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to the list of benign connective tissue tumor of the pancreas.

We Performed an epidemiologic survey for strabismus among primary school-children in order to investigate the number of strabismus from March 1995 to February 1996. Cover-uncover test and prism cover test were used. The results were as follows:1. Out of 9054 1st grade primary school-children examined, 322(3.56%) were found as strabismus. 2. 322 cases of strabismus include 262(81.4%)exodeviation and 60(18.6%) esodeviation. 3. Alternating type and monocular type strabismus have no difference both in exotropia and esotrapia. 4. In exotropia and esotropia, no sexual predilection was found. 5. Most portion of deviation angle distribute between 11 to 20 prism diopter. 6. The difference of number of strabismus between big cities and small cities was statistically insignificant(p>0.05).

This study describes an evaluation of the sonographic, cholangiographic, pathological, and immunological findings, and the protective effect shown by rats reinfected with Clonorchis sinensis. Eight experimental rat groups were, namely, a normal control, a primary infection control, a reinfection I (reinfection 7 week after treatment following 3-week infection), a reinfection II (reinfection 2 week after treatment following 8-week infection), a reinfection III (exploration of the intrahepatic bile ducts 1 week after reinfection 4 week after treatment following 4-week infection), a superinfection, a secondary infection control, and an infection following immunization group. Sonographic and cholangiographic findings showed moderate or marked dilatation of the bile duct confluence in the primary infection control, reinfection II, and secondary infection control groups. Juvenile worms survived in the intrahepatic bile ducts 1 week after reinfection following treatment in the reinfection III group. It was concluded that reinfecting juvenile worms found during the first week following reinfection failed to survive or grow further. Anatomical, pathophysiological, or immunological changes may induce protection from reinfection in rats.

We present the cytologic features of small cell neuroendocrine carcinoma of the liver metastasized from the uterine cervix. Cytologically, tumor cells were arranged in a pat- tern of solid sheet in necrotic background. The tumor cells were characterized by uniform, small cells, round hyperchromatic nuclei, and high nuclear cytoplasmic ratio. The smears showed frequent mitotic figures and rosette formation, These findings were identified with the previous histologic sections of uterine cervix. To make a diagnosis of metastatic small cell neuroendocrine carcinoma on the Papanicolaou smear, a high index of suspicion and careful review of clinical history are needed

Telomerase is an enzyme that maintains telomeres and prevents telomere shortening, and may be linked with cellular proliferation or the aging process. The purpose was to examine telomerase activity in human chorionic villi from early and term normal pregnancies, and to analyze the correlation of telomerase activity (TA) with MIB-1 & bcl-2. A total of 37 placentae were obtained from 16 early and 21 term pregnancies. TA was assayed by telomeric repeat amplification protocol, and immunohistochemical staining was performed for MIB-1 & bcl-2 expression. TA & MIB-1 expression were strong in early placenta, but bcl-2 was highly expressed in term placentae. Thirteen (81.25%) of 16 early placentae showed TA, but only 2 (9.52%) of 21 term placentae expressed TA (p<0.01). MIB-1 was observed in nuclei of cytotrophoblast, and the expression rate was 16.09% in early placentae and 2.87% in term placentae (p<0.01). bcl-2 was observed only in the cytoplasm of syncytiotrophoblast. Term placenta demonstrated stronger expression of bcl-2 compared to early placentae (p<0.05). These findings suggest that TA, MIB-1 & bcl-2 expression are critically regulated over the course of gestation: cytotrophoblast, main cells of early chorionic villi, may be a common source of telomerase and proliferative activity. The TA showed good correlation with cellular proliferative activity. Syncytiotrophoblast, may be a main source of bcl-2 expression which is stronger in the term placentae.

BACKGROUND: Tinea pedis is one of the most comrnon dermatoses in the general population. But its prevalence in the general populat,ion was not yet reported in Korea. OBJECTIVE: Prevalence of tinea pedis and associated tinea unguium were checked in the general population. METHODS: Six hundred fifty eight persons from 179 families of the college students were evaluated. Clinical examinatior. for tinea pedis and onychomycosis and collecting scales from the suspicious lesions of the family members were perforrned by educated college students. Then dermatologists exarnined those specimens mycologically by KOH ~tnount and fungal culture. RESULTS: The results were as follows 1. The prevalence of tinea pedis was 41.2% in the studied 658 persons. 2. Among all 271 patients with tinea pedis, 201 strains of dermatophytes were isolated. They were 143 strains of Trichophyton(T) rubrum, 49 strains of T. mentagrophytes and 9 mixed infections of T. rubrum and T. mentagrophytes. In the co existence of i,inea pedis and tinea unguiurn, isolated species were corresponding. 3. Among 179 families, 143 families (79.9%) had at least one patient with tinea pedis. The isolated species of derrnatophytes in a farnily were one organism, 71.4% and two or more organisms, 28.6% of 77 familiys with more than one patient. CONCLUSION: In our study, the prevalence rate of tinea pedis was 41.2%. That suggests that tinea pedis is a wide spr .ad disease in healthy adult in Korea.
