There are a lot of elements affecting the success of implant prosthesis. The quality of surgical procedure is considered as one of the key factors. To avoid the excess heat generation is an important element of successful osseointegration and it can be achieved by using a gentle surgical technique with a sharp instrument in bone drilling. This study was performed to measure and analyze comparatively the heat transmitted to surrounding bone at a distance of 0.5mm from the periphery of the drill hole in each drilling stage. The results were as follows. In standard system, the temperature of surrounding bone tissue ranged from 29.2degrees Cto 48.3degrees C with irrigation and from 34.6degrees C to 84.3degrees C without irrigation. And in wide system, the temperature of surrounding bone tissue ranged from 29.5degrees C to 52.5degrees C with irrigation and from 34.8degrees C to 87.8degrees C without irrigation. And the temperature ranges exceeded the threshold without irrigation, while showing less than the threshold by the cooling effect of irrigation. In comparing standard system with wide system, although there was no significant difference, 4.3mm pilot and 4.3mm twist drill of wide system showed high value and wide system showed slightly high elevation of temperature in all depth in fixture installation In the finite element analysis, the calculated value by the Fourier's cooling law were applied to the bone drilling surface. And through analysis using different irrigation temperatures at 28degrees C, 15degrees C and 5degrees C, and according to the time. The result was that the cooling water at least below 15degrees C was required to maintain the temperature of surrounding bone less than threshold in bone drilling, the cooling water below 5degrees C was required to gain more sufficient cooling effect, and cooling over 5 seconds was needed after bone drilling for sufficient effect.

This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa of crude extract of T. canis, were found to be positive reaction with sera of dogs infected with D. immitis. However, little or no cross-reaction were observed between sera of D. immitis-infected dogs and crude extract antigen of T. vulpis or A. caninum. These result suggest that there are partial cross reaction between sera of D. immitis-infected dogs and the antigen of T. canis.

The preoperative diagnosis of intraabdominal panniculitis is difficult due to its rarity. However, the increased use of abdominal computed tomography (CT) for a variety of indications has increased the diagnosis of intraabdominal panniculitis, including omental panniculitis. The characteristic CT features of intraabdominal panniculitis are increased attenuation of the adipose tissue, the fat-ring sign, a tumoral pseudocapsule, soft-tissue nodules, and a left-sided orientation of mass maximum transverse diameter. Recognition of these features is valuable in the diagnosis of panniculitis, and hence percutaneous CT-guided biopsy to determine their presence may prevent unwarranted surgery. We report the case of a 61-year-old man found to have an idiopathic isolated omental panniculitis that was diagnosed by abdominal CT and percutaneous CT-guided biopsy.

PURPOSE: It is known that single umbilical artery is frequently associated with gastrointestinal or urogenital anomaly, however, routine renal sonography has been debated in healthy neonate with isolated single umbilical artery. This study is designed to determine the usefulness of routine renal sonography in apparently healthy infants with an isolated single umbilical artery. METHODS: Thirty healthy neonates with a single umbilical artery without a major anomaly from January 1995 to July 2002 were enrolled. The authors investigated the clinical background of babies and their mothers after renal sonography after 72 hours of age. When the abnormalities were found at the first renal sonography, the severity of hydronephrosis and degree of obstruction and renal function were analyzed by follow up renal sonography, voiding cystourethrography(VCUG) and technetium-99m-dimercaptosuccinic acid(DMSA) scan or technetium-99m-mercaptoacetyl-triglycerine (MAG3) scan. RESULTS: Among the 30 healthy patients with isolated single umbilical artery, five patients(16.7%) showed abnormalities on first renal sonography with one major(3.3%) and four(13.4%) minor renal anomaly(minimal or mild hydroneohrosis). One major renal anomaly(severe hydronephrosis) showed severe decreased renal function on MAG3 scan without reflux, and the other four minor regressed spontaneously on follow up study. CONCLUSION: The value of routine early renal sonograpy for detecting renal anomaly in healthy infants with an isolated single umbilical artery remained unclear because most of the anomalies would regress spontaneously in the follow up study.

PURPOSE: The purpose of this study was to compare anxiety, depression and quality of life according to the severity of urinary incontinence in married women. METHOD: The participants were 168 married women aged 30-65 years who experienced urinary incontinence. The data were collected from May to July, 2006 using a structured questionnaire. Frequencies, percent, means and standard deviation, t-test, ANOVA, chi-square-test and Scheffe test with SPSS win 14.0 program were used to analyze the data. RESULTS: The distribution of urinary incontinence severity was mild 87.5%, or moderate 12.5%. Significant differences in the severity of urinary incontinence were found for the general characteristics of age, education level, having a job and having a spouse and for the obstetric characteristics of type of delivery, and menopause. Differences in the score for anxiety (t=-2.41, p=0.001) and quality of life (t=5.50, p<0.001) according to the severity of urinary incontinence were statistically significant. CONCLUSION: Women with moderate to severe urinary incontinence should be screened for psychosocial factors. Severity of urinary incontinence in married women negatively affects their quality of life. Further research is needed to determine factors predicting the quality of life for incontinent women.
