Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.

The Taylor's approach is a special paramedian approach to enter the L5-S1 interspace. The L5-S1 interspace is the largest in vertebral column. This approach is particularly useful when the interspace has been narrowed by pathologic bone destruction such as rheumatoid arthritis or osteoarthritis. Surgery in geriatric patients is associated with a markedly higher incidence of perioperative complication or mortality rate. Optimal anesthetic management of geriatric patients depends on understanding of the normal anatomy and physiologic changes in response to drug in aging. We studied of 3-geriatric patients with Taylor's approach. These patients had problems with respiratory dysfunction and anatomic constraints, which make other approaches unfeasible.

Social capital, defined as an individual’s social relationships and participation in community networks, encompasses resources, such as the exchange of favors, maintenance of group norms, stocks of trust, and exercise of sanctions available to members of social groups. Social capital may lower the risk of mental disorders while increasing the resilience capacity, adaptation, and recovery. Interventions targeting social capital may offer a cost-effective approach to preventing and ameliorating these conditions. This study evaluated the concept and importance of social capital because mental well-being is influenced by individual characteristics, the socioeconomic situation, and broader environmental factors to which individuals are exposed. Recognizing the growing significance of social capital in this context, the study examined its role, its relationship with depression, and the potential importance of social capital in South Korea. Although the definition of social capital is broad, the emphasis is placed on the role of linking social capital. Moving beyond an individual-centric perspective on identifying the factors contributing to depression, this paper suggests that social capital can serve as a crucial starting point for changing the environment to which individuals belong, i.e., structural and intermediary determinants. In the macrolevel perspective of mental health intervention, this paper proposes the need to attribute significance and awareness to numerous studies already implemented in various local communities through social capital.

PURPOSE: The purpose was to compare the marginal fidelity and the fracture resistance of the zirconia crowns according to the various coping designs with different thicknesses and cement types. Material and METHODS: Zirconia copings were designed and fabricated with various thicknesses using the CAD/CAM system (Everest, KaVo Dental GmbH, Biberach., Germany). Eighty zirconia copings were divided into 4 groups (Group I: even 0.3 mm thickness, Group II: 0.3 mm thickness on the buccal surface and the buccal half of occlusal surface and the 0.6 mm thickness on the lingual surface and the lingual half of occlusal surface, Group III: even 0.6 mm thickness, Group IV: 0.6 mm thickness on the buccal surface and the buccal half of occlusal surface and the 1.0 mm thickness on the lingual surface and the lingual half of occlusal surface) of 20. By using a putty index, zirconia crowns with the same size and contour were fabricated. Each group was divided into two subgroups by type of cement: Cavitec(R) (Kerr Co, USA) and Panavia-F(R) (Kuraray Medical Inc, Japan). After the cementation of the crowns with a static load compressor, the marginal fidelity of the zirconia crowns were measured at margins on the buccal, lingual, mesial and distal surfaces, using a microscope of microhardness tester (Matsuzawa, MXT-70, Japan, x100). The fracture resistance of each crown was measured using a universal testing machine (Z020, Zwick, Germany) at a crosshead speed of 1 mm/min. The results were analyzed statistically by the two-way ANOVA and oneway ANOVA and Duncan's multiple range test at alpha= .05. RESULTS: Group I and III showed the smallest marginal fidelity, while group II demonstrated the largest value in Cavitec(R) subgroup (P < .05). For fracture resistance, group III and IV were significantly higher than group I and II in Cavitec(R) subgroup (P < .05). The fracture resistances of Panavia-F(R) subgroup were not significantly different among the groups (P > .05). Panavia-F(R) subgroup showed significantly higher fracture resistance than Cavitec(R) subgroup in group I and II (P < .05). CONCLUSION: Within the limitation of this study, considering fracture resistance or marginal fidelity and esthetics, a functional ceramic substructure design of the coping with slim visible surface can be used for esthetic purposes, or a thick invisible surface to support the veneering ceramic can be used depending on the priority.

Primary angiosarcoma of the greater omentum is extremely rare. We present a case of angiosarcoma arising from the greater omentum in a 56-year-old-woman. She was admitted due to abdominal mass that had found 20 days prior. Abdominal CT scan showed an ill-defined lobulated, well enhanced mass in the right lower abdomen. An omentectomy including the tumor was performed. Histopathological examination showed the excised tumor to be an angiosarcoma. Immunohistochemical studies were strongly positive for vimentin, Factor VIII-relative antigen, and CD34 staining, but were negative for CD68, S-100 protein, and cytokeratin staining. The clinical presentation, course and treatment of the patient are discussed.

Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme 5alpha-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.

Acardiac fetus in triplet pregnancy is a very rare, fatal congenital anomaly that had not been reported in Korea. It only occurs in multiple gestations associated with placental vascular anastomoses between the affected fetus and its co-twin. The major complications associated with acardiac fetus in triplet pregnancy are congestive heart failure in normal pumping fetus, maternal polyhydramnios, preterm labor, intrauterine fetal death, etc, and perinatal diagnosis can be made with the perinatal ultrasonographic examination. We report a case of acardiac fetus in a spontaneous triplet pregnancy at 23 weeks of gestational age with a brief review of the literature.

Cerebrovascular complications are of the most frequent intracranial complications of bacterial meningitis. Most of the previous reports suggest that the prognosis for the pafients with cerebrovascular complications was unfavorable. We recently experienced a case of meningococcal meningitis with fulminant meningococcemia associated with multifocal non-enhancing lesions on, initial brain MRI. These lesions were hyperintense on T2weighted image and were located in left basal ganglia, both medial thalami, periventricular white matter, left cerebellar hemisphere, and right midbrain and were considered to be resulted from small vessel involvement. Gram negative diplococci were detected by Gram staining of specimens from skin lesion. After antimicrobial therapy and glucocorticoid replacement the patient was recovered without any neurologic sequelae. After one month, follow-up MRI showed resolution of all the ischemic lesions except in midbrain. Additionally there was a small focal hemtoma formation in left basal ganglia. The small hematoma was considered to be resulted from rupture of microaneurysm and disappeared on follow up MRI performed after 3 months. This case suggests that the cerebrovascular complications in meningococcal mningitis might be treated successfully.
