We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.

We aimed to study the clinicopathologic features of inflammatory fibroid polyp by histological and immunohistochemical methods. The materials used in this study consisted of 9 cases of inflammatory fibroid polyp: 4 in the stomach, 4 in the small intestine and 1 in the cecum. The results were as follows: Females were affected more frequently than males and the average age was 45 years(range:27-61). In cases of gastric lesion, the size tended to be smaller, the mass was mainly located along the greater curvature side of antrum, and confined to the submucosa. However inflammatory fibroid polyp of the small intestine was over 2.5 cm in size, located along the antemesenteric border, and involved the proper muscle layer. In addition, intussusception was accompanied by polyp in 2 cases of small intestinal lesions. Histologically inflammatory fibroid polyps of the stomach were characterized by prominent lymphocytic infiltration and occasional onion-skinning of stromal cells, whereas plasmocytic infiltration was prominent in those of the small intestine. Main component cells comprising this lesion were confirmed to be fibroblasts by immunohistochemistry which revealed strong reactivity to vimentin in the cytoplasm of slindle cells.

We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

We compared the pigment of melanosis coli with the pigment of Dubin-Johnson syndrome, melanin, and lipofuscin. The pigment of melanosis coli appeared similar to lipofuscin in that it stained positively with periodic acid-Schiff, oil red-0 and Victoria blue stains and revealed negative reactions to the immunohistochemical stains for S-100 protein and neuron specific enolase, but had similarity to melanin as shown by the positive reaction to Fontana-Masson stain and negative autofluorescence. The pigment of Dubin-Johnson syndrome showed the same histochemical and immunohistochemical characteristics as that of melanosis coli. The results indicate that the pigments of melanosis coli and Dubin-Johnson syndrome are identical and are variants of lipofuscin.

A case of low-grade endometrial stromal sarcoma resembling ovarian sex-cord tumor in the uterus of a 43-year-old woman is described. This tumor belongs to the group II category of uterine tumors resembling ovarian sex-cord tumor described by Clement and Scully, and the epithelial-like elements show prominent smooth muscle differentiation, proved by immunoreactivity for desmin and actin. The patient did not receive any adjuvant therapy; she is alive and well without recurrence 8 months postoperatively.

The term endometriosis refers to ectopic endometriume. It most often involves the pelvic organs, including ovaries, broad and round ligaments, fallopian tubes, cervix, vagina and the pouch of Douglas. We report a case of vesical endometriosis in a 4- year old female patient and review literature. Segmental resection of this mass with involved bladder resulted in cure and this lesion was confirmed histologically as endometriosis of the bladder.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

The purpose of this study was to analyse the center of resistance of the maxillary first molar using the 3-dimension finite element method. An extracted maxillary first molar of normal shape and average root length was selected and sectioned every 1.5mm parallel to the cementoenamel junction. Each section was traced and digitized to construct 3-D finite element model of the maxillary first molar. After a certain magnitude of counterbalancing moment(M) was applied to the tooth, a varying single force(F) of distomesial direction was applied to a certain point of the tooth until the tooth was translated. The force producing translation(Ft) was substituted to the equation deltad = M/Ft to calculate the center of resistance of the maxillary first molar. And reducing the alveolar bone level 1.68mm, and 3.36mm below to the cementoenamel junction, the tooth movement was analysed to see the effect of reducing the alveolar bone level to the location of the center of resistance. The results were as follows; 1. The center of resistance of the maxillary first molar was 3.72mm apical, 1.10mm buccal, and 0.71mm mesial to the geometric center of the horizontally sectioned surface at the cementoenamel junction. This point was 0.36mm apical, 1.20mm buccal, and 0.71mm mesial to the trifurcation point, indicating that it was not on the tooth root. 2. As the alveolar bone level was reduced, the center of resistance of the maxillary first molar was moved to the apical direction.

Authors examined 40,000 minifilms(boys and girls each 10,000 in junior and senior high schools) which were taken for survey of pulmonary tuberculosis for junior and senior high school students and checked the prevalence of scoliosis. It was considered lateral curvature of spine more than 10 degrees as nonpostural scoliosis, which were analyzed prevalence rate, degree of curvature, distribution of size of curvature, pattern of curve and direction of curvature. Following results were obtained. 1. The overall prevalence rate was 1.56; male 1.38. and female 1.70%(Junior high school 1.06%, Senior high school 2.05%). 2. Scoliosis secondary due to bony abnormality was found in 5 cases. 3. The most common pattern of curvature was the thoracic curve. 4. In sihgle curve, right to left ratio was 1.7, especially senior high school girls had more right curve and junior high school boys had more left curve. 5. The prevalence of senior high school students was greater than that of junior high school students and the degree of curvature was also severe in senior high school students than in junior high school students.
