BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

Renal cell carcinoma may metastasize to various portions of the body but dissemination to the prostate is very rare. The presenting symptom of a 79 year old man was acute urinary retention which was clinically thought to be benign prostatic hyperplasia. Radical nephrectomy was performed 22 months ago due to renal cell carcinoma. The histologic examination of the transurethral resection specimen demonstrated metastatic renal cell carcinoma and there was no distant metastasis except the lymph node.

PURPOSE: We investigated whether psychological factors could influence on the symptoms of chronic prostatitis based on general population that have not previously been examined or treated. MATERIALS AND METHODS: Between August and November 2000, we randomly selected 100 male residents in the area of Chung-nam including Daejoen city. The participants completed self- administered questionnaires. Based on our inclusion criteria, 87 participants were included in this study. RESULTS: Scores of Beck Depression Inventory of participants with higher pain and urinary symptoms domain scores were significantly higher than those with lower pain and urinary symptoms domain scores of the National Institutes of Health-chronic prostatitis symptom index (p=0.001 and p=0.028, respectively). However, anxiety did not influence on the symptoms of chronic prostatitis based on the results of State-Trait Anxiety Inventory. Based on the results of Bem Sex Role Inventory, masculinity score of participants with higher urinary symptoms domain scores were significantly lower than those with lower urinary symptoms domain scores (p=0.042). CONCLUSIONS: Our results suggest that psychological problems may involve in an early stage of chronic prostatitis and have a causative role in chronic prostatitis.

Purpose: This study compared the effects of a high glycemic load (high GL) diet and low glycemic load (low GL) diet on the body weight, body fat, blood pressure, and blood lipid indicators. Methods: Twenty-one young adults aged between 21 and 28 years who were overweighted or obese (body mass index [BMI] between 23 and 33.5 kg/㎡ ) before the study and after calorie reduction diets with either low GL or high GL for 2 weeks each were examined.The study was a randomized crossover design with a 2-week washout period between the 2 types of diet. The order of the low GL and high GL diet periods was randomized. The body weight, body fat, blood pressure, levels of blood lipids, fasting glucose, insulin, homeostatic model assessment (HOMA) insulin, C-peptide, and HOMA C-peptide were measured at the baseline, as well as 2, 4, and 6 weeks after starting the experiment. Results: When subjects were on the low GL diet, they lost more weight than those eating the high GL diet (mean ± SD, −2.77 ± 1.09 vs. −1.56 ± 0.78 kg; p < 0.001); there were greater decreases in body fat mass (−1.62 ± 1.19 vs. −0.88 ± 0.91 kg; p = 0.024) and BMI (−0.95 ± 0.32 vs. −0.56 ± 1.08 kg/㎡ ; p < 0.001). On the other hand, there were no significant differences in changes in biochemical parameters, such as blood lipids and fasting glucose levels, and blood pressure. The body weight, body fat mass, BMI, percent body fat, blood pressure, cholesterol (total, low-density lipoprotein, and high-density lipoprotein), fasting glucose, C-peptide, HOMA-insulin resistance-C-peptide levels were decreased significantly at 6 weeks. Conclusion The low GL diet may be more effective in losing body weight, body fat mass, and BMI than the high GL diet for 2 weeks in healthy young overweight or obese adults.

PURPOSE: Changes in human body composition can affect the accuracy of spine bone mineral density (BMD) measurements. The purpose of this study was to evaluate whether fat and water in the soft tissue of the abdomen influence lumbar spine BMD measurements obtained using dual energy X-ray absorptiometry (DXA). MATERIALS AND METHODS: Duplicate BMD measurements were carried out on healthy volunteers (10 men and 10 women) and the Hologic anthropomorphic spine phantom had on the same day before and after placement of following 3 materials in the abdominal area: lard 900 g, 1.5 cm thick; oil 1.4 liters in a vinyl bag; and water 1.2 liters in a vinyl bag. RESULTS: In the case of human participants, following the placement of exogenous water to mimic extracellular fluid (ECF), there was a significant decrease in lumbar spine BMD (-0.012 g/cm2, p=0.006), whereas the placement of exogenous lard and oil to mimic abdominal fat produced a slight increase in lumbar spine BMD (0.006 g/cm2, p=0.301; 0.008 g/cm2, p=0.250, respectively). The average percentage of lumbar spine BMD change with and without exogenous lard, oil, and water showed increase of 0.51%, and 0.67%, and decrease of 1.02%, respectively. Using the phantom, BMD decreased with the placement of both lard (-0.002 g/cm2, p=0.699) and water (-0.006 g/cm2, p=0.153); however, there was no difference in BMD after oil placement. CONCLUSION: These results suggest that in cases where changes in fat and ECF volume are similar, ECF exerts a greater influence than fat on DXA lumbar BMD measurements.

We report here on a rare case of hepatoid thymic carcinoma in a 34-year-old man. The patient complained of a high fever and headache, and a 6.6cm-sized anterior mediastinal mass was found on chest computed tomography (CT). There was no hepatic mass seen on abdominal CT. The resected mass consisted of epithelioid cells with abundant eosinophilic cytoplasm, pleomorphic vesicular nuclei and prominent nucleoli, and the mass was surrounded by thymic tissue. The tumor cells were immunopositive for cytokeratin 7, alpha-1-antitrypsin, hepatocyte staining, and epithelial membrane antigen, but they were negative for CD5, alpha-fetoprotein (AFP) and placental alkaline phosphatase, and this all led to a diagnosis of hepatoid thymic carcinoma rather than hepatoid yolk sac tumor. This entity should be included in the differential diagnosis of epithelioid thymic tumors.

STATEMENT OF PROBLEM: Over the past decade, increased demand for esthetically pleasing restorations has led to the development of all-ceramic systems. Recent reports suggest that the all-ceramic crowns have excellent physical properties, wear resistance, and color stability. In addition, numerous ceramics have excellent biocompatibility, a natural appearance, and improved physical bonding with resin composite luting agents. However, the brittle nature of ceramics has been a major factor in their restriction for universal usage. Functional occlusal loading can generate stress in the luting agent, and the stress distribution may be affected by the marginal geometry at the finish line. Tooth preparation for fixed prosthodontics requires a decision regarding the marginal configuration. The design dictates the shape and bulk of the all ceramic crowns and influences the fit at the margin. PURPOSE: The purpose of this study was to evaluate the stress distribution within marginal configurations of all- ceramic crowns (90-degree shoulder, 110-degree shoulder, 135-degree shoulder). MATERIAL AND METHODS: The force is applied from a direction of 45 degrees to the vertical tooth axis. Three-dimensional finite element analysis was selected to determine stress levels and distributions. RESULTS AND CONCLUSION: The result of stress level for the shoulder marginal configuration was more effective on stress distribution at 135-degree shoulder margin. But the stresses concentrated around at 135-degree shoulder margin. The stress decreased apically at the surface between cements and alumina core, and increased apically at the surface between alumina core and veneering porcelain.

The relationship between obesity and ketonuria is not well-established. We conducted a retrospective observational study to evaluate whether their body weight reduction response differed by the presence of ketonuria after fasting in the healthy obese. We used the data of 42 subjects, who had medical records of initial urinalysis at routine health check-up and follow-up urinalysis in the out-patient clinic, one week later. All subjects in the initial urinalysis showed no ketonuria. However, according to the follow-up urinalysis after three subsequent meals fasts, the patients were divided into a non-ketonuria group and ketonuria group. We compared the data of conventional low-calorie diet programs for 3 months for both groups. Significantly greater reduction of body weight (-8.6 +/- 3.6 kg vs -1.1 +/- 2.2 kg, P < 0.001), body mass index (-3.16 +/- 1.25 kg/m2 vs -0.43 +/- 0.86 kg/m2, P < 0.001) and waist circumference (-6.92 +/- 1.22 vs -2.32 +/- 1.01, P < 0.001) was observed in the ketonuria group compared to the non-ketonuria group. Fat mass and lean body mass were also more reduced in the ketonuria group. In addition, serum free fatty acid concentration after intervention in the ketonuria group showed significant more increment than in the non-ketonuria group. The presence of ketonuria after fasting may be a predicting factor of further body weight reduction.
