BACKGROUND: Among malignant diseases, gastric cancer remains a major cause of death in Korea. Many variables are considered to be important to the prognosis of patients with gastric carcinomas. METHODS: The authors evaluated the 5-year survival rates and analyzed the prognostic factors in 448 patients with gastric cancer who had under gone a gastric resection during the period between Dec. 1984 and Dec. 1992. RESULTS: The overall 5-year survival rate was 50.5%, and the survival rates according to the stage were stage Ia, 97.4%; Ib, 56.5%; II, 48.4%; IIIa, 41.6%; IIIb, 7.1%; and stage IV, 14.3%. Univariate analysis was used to relate prognostic factors, such as tumor size, gross type, depth of invasion, lymph node involvement, positive lymph node ratio, distant metastasis, complications, the surgical curability, and the TNM stage, with the survival of the patients. In a multivariate analysis using 11 variables, the TNM stage was the most significant prognostic factor. Besides the TNM stage, the depth of invasion, a lymph node involvement, a positive lymph node ratio, and complications were considered as independent prognostic factors influencing survival. CONCLUSIONS: The current TNM staging system appears to be a reasonable one, and the TMN stage of the tumor at the time of surgery is the most important prognostic factor.

The results of a retrospective study on 197 cases of malignant skin tumors, which were operated from July 1991 to June 1996 were presented. 1. Primary malignant skin tumors in our series included basal cell carcinoma (42%), squamous cell carcinoma (39%), melanoma (7%). Eighty five percentage of them were developed after 5th decade. There was a slight male preponderance (male to female ratio; 1.2:1). 2. seventy five percentage of malignant skin tumors were occurred in the head and neck. However 34% of squamous cell carcinoma occurred in the extremities. 3. Overall recurrence rate was 7.1% and overall metastasis rate was 7.6%. Seven cases (8.5%) of basal cell carcinoma were recurred without metastasis and seven cases (53.8%) of melanoma were meatastasized without recurrence. 4. Overall recurrence occurred at average 27 months after primary resection and 79% of them occurred in the head and neck. Among 14 recurred tumors, one recurred secondarily and three were metastasized elsewhere. 5.Two thirds of metastasis occurred within one year of resection. Mortality rate in the patients with metastasis was 40%. Metastases involved multiple organs and involved lymph nodes most frequently. 6.Fifteen patients with metastasis were treated with surgery alone (2 cases), surgery and adjuvant therapy (3 cases), radiation and/or chemolherapy without surgery (6 cases), and no therapy(4 cases).

Ossifying fibromyxoid tumor of soft parts is a rare soft tissue neoplasm of uncertain histogenesis. It occurs commonly as a subcutaneous or intramuscular mass in the extremities and trunk, but rarely in the head and neck region. Its biologic behavior is generally benign, but a locally aggressive clinical course due to a pseudocapsule containing nests of tumor cells. Herein we report a case of a benign ossifying fibromyxoid tumor which occurred in the right temple in 34-year-old woman. The tumor was located in the temporalis muscle and completely removed with clear margin through bicoronal approach. The lesion was 2.0 x 2.5 x 3.0cm sized white to tan colored, well demarcated, firm mass. The tumor was covered by a fibrous capsule, and there was incomplete shell of lamellar bone at the periphery of the nodule. The tumor cells were uniformly round, ovoid, or spindle-shaped in collagenous and myxoid stroma. During 1 year's postoperative follow-up, the patient had no local recurrence.

BACKGROUND AND OBJECTIVES: The myogenic response was originally described as a contraction of a blood vessel that occurred following an increase in intravascular distending pressure. Conversely, a reduction in intravascular pressure produces myogenic vascular relaxation. Recent attention has focused on the potential role of this myogenic mechanism in the control of tone in the resistance vasculature, and in particular on how this mechanism may contribute to the increased vascular resistance seen in hypertension. Therefore, in the present study, we investigated the role of myogenic tone in the generation and/or maintenance of hypertension. MATERICAL AND METHODS: Myogenic tone was developed by stretching of the basilar arteries of WKY (istar Kyoto rat) and SHR (spontaneously hypertensive rats). Contractile responses, PKC (protein kinase C) immunoblots and translocation of PKC and RhoA were measured. In the presence of extracellular Ca2+ the stretching of the resting vessel evoked a myogenic contraction in the basilar arteries of SHR and WKY. Myogenic tone was significantly greater in SHR than in WKY. However, in the absence of extracellular Ca2+, stretching evoked a myogenic contraction in SHR, but not in WKY. The stretch-induced myogenic tone was inhibited by nifedipine. The effect of nifedipine was similar in both SHR and WKY rats. H-7, calphostin C and Y-27632, also inhibited stretch-induced myogenic tone in both SHR and WKY. The inhibitory effects of these drugs were greater in SHR than in WKY. Immunoblotting showed rho A and PKC alpha were translocated from the cytosol to the cell membrane with stretching in both SHR and WKY. PKC beta, however, was translocated to the cell membrane with stretching in SHR, but not in WKY. CONCLUSION: These results suggest that stretch-induced myogenic tone is significantly greater in SHR than in WKY. Furthermore, the increase in amount and/or activity of PKC beta and ROK (rhoA-associated kinase) may be a key mechanism accounting for the enhanced myogenic tone in SHR.

Plastic surgeons have been in pursuit of natural appearance in rhinoplasty, which means harmonious relationship between nasal tip and dorsum. If silicone implant is used alone for the augmentation of the nasal tip, there is a possibility of the thinning of the nasal tip skin and exposure of implant. For these reasons, plastic surgeons have used a cartilage fixation over the silicone implant for nasal tip augmentation. However, fixation by sutures is technically challenging, so authors tried to use Histoacryl glue instead of sutures. Twelve New Zealand white rabbits were used in this study. Four 5mm diameter and 1mm thick cartilages were harvested from ear. Two cartilages were fixed to the silicone blocks by chromic catgut and the others were attached by Histoacryl glue. Four cartilage-silicone complexes were implanted into the subcutaneous pocket of the rabbit's head. In the 1st, 3rd and 5th week, the cartilage- silicone complexes were harvested and the shearing forces between cartilages and silicones were measured by texture analysis. The shearing forces were not changed in the Histoacryl group with the lapse of time but decreased in the suture group. However, the difference between the 2 groups were not statistically significant. The histologic findings of both groups showed progressive fibrosis. This study showed the possibility of using Histoacryl glue as a simple method of fixing cartilage to the silicone.

PURPOSE: Giant cell tumor is the second most common benign neoplasm in upper extremity. Unlike usual chief complaint of painless mass, an atypical case with giant cell tumor presented a distinguishing characteristics of which accompany pain and tenderness and is histologically giant-cell free. METHODS: A 31-year-old male patient complained of a rapid growing painful mass on the proximal phalanx of the left ring finger. Under microscopic operation, a 1.6 x 1.3cm sized mass was found to be surrounded by areolar tissue and attached to a tendon sheath, encircling the digital nerve and artery. Diagnostic confirmation was assisted by positive finding in histologic immunohistochemical stain-CD68. Characteristic pathologic finding is an atypical distribution of spindle cells & histiocytes without giant cells in fascicular pattern. RESULTS: Giant cell tumor was carefully removed under microscopic approach, while preserving digital nerve & artery. In postoperative 13th month, the patient presented with a 6mm of static two-point discrimination test, similar to that of the adjacent fingers. CONCLUSION: We report an atypical case with painful mass on tendon sheath, surrounding the digital nerve and artery that was diagnosed of giant cell tumor, but without giant cells on pathology. This case provides broader understanding of the giant cell tumor that should not only rely its typical findings of the painless mass and positive sign on H&E stain.

PURPOSE: The objective of this study was to develop a new scoring tool that is comprehensively applicable and predicts fatality within 24 h of intoxication. METHODS: This was a cohort study conducted in two emergency medical centers from 2011 to 2012. We identified factors associated with severe/fatality. Through a discriminant analysis, we devised the aBIG (age, Base deficit, Infection, and Glasgow coma scale) score. To compare the ability of aBIG to predict intoxication severity with that of previous scoring systems such as APACHE II, MODS, SAPS IIe, and SOFA, we determined the receiver operating characteristic curves of each variable in predicting severe-to-fatal toxicity. RESULTS: Compared with the mild/moderate toxicity group (n=211), the severe/fatal group (n=143) had higher incidences of metabolic acidosis, infection, serious mental change, QTc prolongation and hepato-renal failure. Age, base deficit, infection-WBC count, and Glasgow Coma Scale were independently associated with severe/fatal poisoning. These variables were combined into the poisoning "aBIG" score [0.28xAge group+0.38xWBC count/10(3)+0.52xBase deficit+0.64x(15-GCS)], which were each calculated to have an area under the curve of 0.904 (95% confidence interval: 0.868-0.933). The aBIG poisoning score had an equivalent level of severity predictability as APACHE II and a superior than MODS, SOFA, and SAPS IIe. CONCLUSION: We developed a simplified scoring system using the four variables of age, base deficit, infected leukocytosis, and GCS. The poisoning aBIG score was a simple method that could be performed rapidly on admission to evaluate severity of illness and predict fatal severity in patients with acute intoxications.
