Localized or solitary fibrous tumor (SFT) of the pleura has been classified as a type of mesothelioma, arising from the submesothelial connective tissue cells. The preoperative diagnosis of the tumor at the cytologic or histologic level is very important for the proper handling of the lesion. This preoperative diagnosis is now possible by means of the advance in the transthoracic fine needle aspiration biopsy (FNA) techniques and in the very experience of the cytopathologists. We describe FNA cytologic feature of two cases of SFT arising from the pleura. Cytologic, histologic, immunohistochemical, and electron microscopic characteristics of pleural SFT are discussed. The tumor cells of SFT are spindle or oval in shape with a variable amount of cytoplasm. They are arranged in irregular trabeculae intimately ass- ociated with capillaries. A unique cytologic feature observed in this tumor is that thick, eosinophilic, amorphous collagen bundles are scattered between tumor cells

BACKGROUND: The purpose of this study was to measure and compare the optimum depth of the internal jugular venous catheterization between the right and left side. METHODS: Forty-four patients were enrolled for this study and divided into two groups (22 patients each). The optimum depth of the catheterization was calculated using the sum of two component (A and B); the advanced length of the catheter from the level of the cricoid cartilage (A) and the distance from the catheter tip to the junction of the superier vena cava and right atrium (B). RESULT: The optimum depths of the internal jugular venous catheterization were 16.0 1.0 cm (right) and 18.4 1.5 cm (left) respectively. Left side was significantly longer than right side (p<0.05). In this study, we experienced some complications; arterial punctures (5 cases) and migration of the catheter to the opposite subclavian vein (1 case). Five complications were associated with left internal jugular venous cannulation and one was associated with the right side cannulation. CONCLUSION: We concluded that the optimum depth of the internal jugular venous catheterization was longer in the left side than in the right side.

PURPOSE: We evaluated the risk factors and related results of residual diplopia and enophthalmos in patients who had orbital wall fracture repair. METHODS: 50 patients with orbital wall fracture who were followed up for at least 6 months postoperatively were included in this study. We analyzed effects of the patient age, timing of surgery, size and location of fracture on development of postoperative diplopia and enophthalmos. RESULTS: 32 patients had diplopia and 16 patients had enophthalmos greater than 2 mm. Among 32 patients with preoperative diplopia, 9 patients experienced postoperative diplopia. Among 16 patients with preoperative enophthalmos, 5 patients experienced postoperative enophthalmos. Delayed timing of surgery was a significant factor for development of postoperative diplopia and enophthalmos. Age of the patients and fracture size were not significant factors for development of postoperative diplopia and enophthalmos. CONCLUSIONS: Early surgical repair of orbital wall fractures decreases the incidence of residual diplopia and enophthalmos. Preoperative assessment of multiple variables could help to achieve cosmetical and functional better results.

The accidental swallowing of foreign body is a common problem in the children. We describe the case of 37-month-old girl in whom a gastric ulcer was caused by the ingestion of three magnets. This case report demonstrates that if more than one magnet were swallowed, they should be removed even if there are no sharp edges and small size. Because the magnets will attract each other and hold the intestinal walls between them, causing necrosis and resulting in intestinal perforation or a fistula.

The principal objective of this study was to assess the nutritional status and dietary quality in low-income elderly individuals residing at home (LH) or in health care facilities (LHCF) with dietitian. This study was conducted via anthropometric measurements, questionnaire interviews, and dietary surveys using a 24 hr recall method with 120 low-income elderly individuals (LHCF=46, LH=74). The average ages of the LH and LHCF group were 76.3 years and 78.6 years, respectively. The LH group evidenced a significantly higher frequency of skipping meals than the LHCF group. The average energy intakes of the LHCF and LH group were 1921.0 kcal and 1443.9 kcal, with a significant difference (p<0.001). Most of the nutrient intake and intake rates for recommended intake were significantly higher among the LHCF group as compared with the LH group. The LHCF group showed significantly higher values for the nutrient adequacy ratio (NAR), the mean adequacy ratio (MAR), nutrient density (ND), and the index of nutritional quality (INQ) by dietary qualitative estimation than in the LH group. The Korean diet diversity scores (KDDS) were 3.66 for LH group and 4.93 for the LHCF group, thus were significantly higher in the LHCF group than in the LH group. The results of the present study demonstrate that the LH group appeared to experience more dietary problems than the LHCF group. It was suggested that nutritional education is needed for low-income elderly individuals living at home, in order for them to learn proper dietary management. This can be achieved via educational programs in social welfare institutions, incentives toward employment as a dietitian, and implementation of community-based support.

The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y Aged* ; Aging ; alpha-Tocopherol ; Ascorbic Acid ; beta Carotene ; Blood Pressure ; Body Mass Index ; Free Radicals ; Humans ; Hypertension ; Ideal Body Weight ; Incidence ; Obesity* ; Oxidative Stress ; Plasma* ; Ulsan* ; Uric Acid ; Waist-Hip Ratio

Bacterial endophthalmitis is an ocular emergency that requires rapid diagnosis and therapeutic decision making. The introdection of intravitreal injection of antibiotics has been a major advancement because it has resulted in a marked improvement in visual outcome. The intravitreal injection of steroids may be potentially useful in the treatment of endophthalmitis and other ocular inflammatory diseases. Forty eyes of pigmented rabbits were used, and divided into two groups. Group I was eyes without vitrectomy. In the right eye, 100 microliter of 1mgvancomycin, 400 microliter amikacin and 400 microliter dexamethasone injected was done. Group II was eyes with vitrectomy and lensectomy. At 2 weeks after lens and vitreous removal, rabbit eyes received an injection of a combination of 1mg vancomycin, 400 microliter amikacin and 400 microliter dexamethasone in right eye and BSS in left eye. The effect of combination injection was examined by light and transmission, scanning electron microscope at 3 days, 1 week, 2 weeks and 6 weeks following injection. The injection of combination without vitrectomy produced no toxicity. After injections of either combination or BSS after vitrectomy, macrophages were observed on the surface of retinal pigment epithelium and disorganized outer segments. This finding seems to be produced by vitrectomy procedure rather than drug toxicity. These results supports the hypothesis that the injection of these combinations is not toxic to aphakic/vitrectomized eyes.

Almost all advanced glomerular diseases have glomerular sclerotic changes to varying degrees whatever causes their primary glomerular disease are. Pathogenesis of these sclerosis has been thought of as the hyperfiltration in the primary glomerulosclerosis due to development of glomerular hypertension in each insulted glomeruli. This background gave the theoretical bases for antihypertensive therapies for supporting chronic renal insufficient patients. Angiotensin converting enzyme (ACE) inhibitor, one of the antihypertensive drugs, has received attention recently for its effectiveness. The aims of this study determined the effects and mechanism of the ACE inhibitor, enalapril, on the glomerulosclerosis in FGS/NgaKist mice, which was an animal model of chronic renal failure by generating spontaneously heavy proteinuria and progressive glomerulosclerosis. Five-week-old FGS/NgaKist mice (n=38) were assigned to four groups. Group 1a (n=6) and group 2a (n=8) fed with a vehicle, were sacrificed at the end of 10 weeks and 15 weeks, respectively. Group 1b (n=12) and 2b (n=12) received enalapril (100 mg/L) in drinking water for 5 weeks and 10 weeks from 6th week of age respectively, and were sacrified on the same day as the control groups. Doses of enanapril were maintained to 2 mg/kg/day by measuring the amount of water consumption. In enalapril groups 1b and 2b, systemic blood pressure (74.7 14.0 mm Hg, 74.3 15.9 mmHg) were significantly lower than control group 2a (116.1 4.6 mmHg, P<0.001). Similarly, degree of proteinuria lowered in enalapril group 2b versus control group 2a (0% and 50.0%, P<0.001). Glomerulosclerosis percentage significantly decreased (P<0.001) (group 1b and 2b; 1.9 6.5, 5.6 7.0 vs control 1a and 2a; 32.8 15.5, 31.4 13.8). Glomerulosclerosis score also decreased (P<0.001) (group 1b and 2b; 0.02 0.08 vs control 1a and 2a; 0.48 0.12, 0.30 0.14). The immunofluorescent staining of enalapril groups showed negative for mesangial deposition of IgG, IgA, IgM, and C3 which were positive in control groups. Immunohistochemical staining with TGF-beta1 was negative in enalapril groups and sclerotic glomeruli both enalapril groups and control groups. These results support that the ACE inhibitor has a renoprotective effect on glomerulosclerosis not only by decreasing the blood pressure but also by suppressing the immune deposits on glomeruli.
