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.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear molding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known.

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.

OBJECTIVES: The purpose of this study was to identify the correlation coefficient of knowledge about multicultural, and attitude toward migrant wives by nursing Students. METHODS: Research participants of this study were 212 students attending nursing university in Seoul, Gyeonggi-do, Jeollanam-do. A self-report instrument was used to measure knowledge about multicultural and attitudes toward migrant wives. Descriptive statistics, t-test, Mann-Whitney test, ANOVA and Pearson's correlation analysis with SPSS/Win 20.0 were used. RESULTS: The mean knowledge about multicultural was 8.10 out of 13 and the mean attitudes toward migrant wives was 2.45 out of 5. Factors affecting knowledge about multicultural were age. Factors affecting attitudes toward migrant wives were age, residential district, experience of overseas trip, experience of living abroad and foreign language fluency. There was a positive correlation between knowledge about multicultural and attitudes toward migrant wives. CONCLUSION: Developing knowledge about multicultural and positive attitudes toward migrant wives is necessary in nursing school curricula. Therefore, nursing educator should make actual and effective education program.

STATEMENT OF PROBLEM: Proper finishing and polishing enhance both the esthetics and the longevity of restored teeth. Blade finishing technique would be suited for smoothing and finishing. Evaluation of this technique are necessary. PURPOSE: The purpose of this study was to evaluate the blade finishing and polishing procedures on the surface profile and roughness of ormocer-based composite resin and nanohybrid composite resin. MATERIAL AND METHODS: The material included a ormocer-based composite resin (Admira(R) & Admira(R) Flow); a nanohybrid composite resin (Grandio(R) & Grandio(R) Flow). One hundred forty specimens of each group were prepared using a mylar strip and randomly divied into blade finishing and rubber polishing groups (n=10). The average surface roughness (Ra) in micrometers was measured and the surface profile was examined by scanning electron microscopy (SEM) (Magnification X 200). The data were analyzed by Mann-Whitney Test at 0.05 significance level. CONCLUSION: The results of this study indicated that the mylar strip produced the smoothest surface on all materials and among the finishing-polishing methods was not significanct difference (P>0.05). Ormocer-based flowable composite resin performedthe lowest variability in initial surface roughness among the tested materials.

OBJECTIVES: This study examined whether depressive symptoms and social isolation were independent predictors of 2-year all-cause mortality among the elderly using data from a population-based cohort study. METHODS: In total, 1,033 participants (320 men and 713 women) older than 60 years of age participated in this study. Depressive symptoms, social isolation status, and socio-demographic and health-related covariates were assessed at baseline. The primary outcome measure was 2-year all-cause mortality. Data were collected through in-person interviews by trained interviewers. The GENMOD procedure was used to calculate relative risks (RRs). RESULTS: Of the 1,033 participants, 102 (40 men and 62 women) died within the follow-up period of 2 years. During the 2-year follow-up period, 17.8% of depressed men and 12.3% of depressed women died, and 29.8% of socially isolated men and 14.9% of socially isolated women died. Social isolation was an independent predictor of mortality in elderly men (adjusted relative risk [aRR], 4.6, 95% confidence interval [CI], 2.0 to 10.2), while depressive symptoms were an independent predictor of mortality in elderly women (aRR, 2.0; 95% CI, 1.2 to 3.6) when controlling for potential confounding factors. However, the depressive symptoms detected using the geriatric depression scale were not associated with mortality in men, and social isolation was not associated with mortality in women. CONCLUSIONS The effects of depressive symptoms and social isolation on 2-year all-cause mortality within an elderly population differed according to gender. Gender-specific community-based interventions must be developed to potentially reduce 2-year all-cause mortality among the elderly.

Purpose: We evaluated the clinical manifestations of, and risk factors for, infectious keratitis in patients with ocular graft-versus-host disease (GVHD). Methods: A total of 11 patients who developed infectious keratitis after a diagnosis of ocular GVHD between January 2015 and December 2020, and 36 who did not (the control group), were included in this retrospective study. We recorded sex, age, any underlying disease, any other organ affected by systemic GVHD, systemic immunosuppressant use, follow-up duration, clinical manifestations, the severity of ocular GVHD prior to infection, the size of the epithelial defect, the depth of infiltration, hypopyon status, and the results of microbiological tests. Systemic and ocular indices (including systemic GVHD status) were compared using the chi-squared test. Risk factors for infection were identified. Results: Of the corneal indices, the presence of corneal filaments, the extent of corneal neovascularization, and the number of corneal epithelial defects were significantly higher in the infected group (p = 0.023, p = 0.004, and p = 0.001, respectively). GVHD severity was also significantly higher in that group (p < 0.001). The presence of corneal filaments, corneal neovascularization, and corneal epithelial defects prior to infection correlated significantly with the risk of infection (p = 0.046, p = 0.010, and p = 0.003, respectively). Multivariate analysis identified corneal epithelial defects as a significant risk factor for infection (p = 0.029). Conclusions In patients with ocular GVHD, corneal epithelial defects, corneal neovascularization, and corneal filaments prior to infection were associated with the development of infection. In particular, corneal epithelial defects before infection was a significant risk factor for infection.

Purpose: To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea. Methods: Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment. Results: After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients. Conclusions AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.

OBJECTIVES: In the third trimester hypertensive pregnancies, we would like to evaluate effects of white coat hypertension, severity of hypertension and diurnal variation of blood pressure on the fetal outcome by using 24- hour ambulatory blood pressure monitoring. METHODS: Hypertensives(n=50) and normotensives (n=14) in the third trimester of the pregnancy underwent 24-hour ambulatory blood pressure monitoring. We excluded hypertensives(n=5) who became pre-eclampsia patients. Hypertensives(n=45) were classified as white coat hypertensives(n=14, mean ambulatory blood pressure <139/87mmHg) and sustained hypertensives(n=31). Sustained hypertensives(n=31) were divided as moderate to severe hypertensives(n=5, systolic blood pressure >160 mmHg or diastolic blood pressure >100mmHg) and mild hypertensives(n=26). Sustained hypertensives were also divided into two groups which had diurnal variation of blood pressure or not. To exclude effects of hypertension severity, effects of diurnal variation were evaluated in hypertensives with similar mean arterial blood pressure. Gestational age, body weight, body weight for gestational age were used as parameters of the fetal outcome. RESULTS: 1) The prevalence of white coat hypertension was 28%(14/50). 2) There were no significant differences in the fetal outcome between normotensives(n=14) and white coat hypertensives(n=14). 3) Body weight of fetus and body weight for gestational age in moderate to severe hypertensives(n=5) were less than those of mild hypertensives(n=26), but gestational age was not significantly different between two groups. 4) Body weight of fetus and body weight for gestational age in sustained hypertensives without diurnal variation(n=10) were less than those with diurnal variation(n=8), but gestational age was not significantly different between two groups. 5) All hypertensives who became pre-eclampsia (n=5) were severe hypertensives and had no diurnal variation of blood pressure. CONCLUSION: White coat hypertension in the third trimester was quite often and did not affect on the fetal outcome. The more severe hypertension and/or absence of diurnal variation of blood pressure caused poor fetal outcome. Patients who became pre-eclampsia were severe hypertensives and had no diurnal variation of blood pressure. Ambulatory blood pressure monitoring may have several roles in the antenatal management of hypertenison.
