BACKGROUND: Hyaluronic acid (HA) is a mucopolysaccharide that occurs naturally throughout the human body, where it attaches to collagen and elastin to form cartilage, and also helps maintain the strength and flexibility of the cartilage that cushions joints. A decline in HA synthesis may lead to a variety of symptoms, ranging from joint discomfort, to wrinkles. Cross-linked HA is a viscoelastic solid that resists in vivo degradation by hyaluronidase for much longer than endogenous HA, and which is also a key ingredient in various cosmetics. OBJECTIVE: To describe our experience with three kinds of Elravie(R) fillers. METHODS: We obtained images of filler shape using a folliscope. Scanning electron microscopy (SEM) was used to compare particle sizes. Hydrophilic filler is a hydroxyl, and for this reason, we mixed the filler with water. Next, PARKER ink was added to the mixture, and viscosity and elasticity were measured using a rheometer. RESULTS: Among the tested fillers, particle size was largest in the Restylane(R) SubQ. Elravie(R) ultra volume filler was greater in volume than Elravie(R) deep line, and Elravie(R) light fillers. We confirmed Elravie(R) fillers to be hydrophilic. Elravie(R) ultra volume filler was found to have the highest viscosity and elasticity, whilst Elravie(R) light filler had the lowest. CONCLUSION: All three kinds of Elravie(R) fillers were found to be suitable for human cosmetic use.

PURPOSE: The objective of this study was to investigate the effects of radiofrequency energy on human chondrocyte viability, and to correlate confocal laser microscopy fluorescence to sulfate uptake and to the histological integrity of articular cartilage. MATERIALS AND METHODS: The chondroplasty procedure for chondromalacic articular cartilage was performed using a 3.0-mm ArthroWand (Arthroscopic Electrosurgery System, ArthroCare Corporation) on fresh human articular cartilage. Radiofrequency energy was applied to the cartilage surface through the probe at a velocity of 10-mm per second in contact and non-contact mode. Three power settings were used. The treated cartilage was analyzed for chondrocyte viability by confocal laser microscopy and (35)S uptake. RESULTS: Confocal laser microscopy demonstrated partial-thickness chondrocyte death irrespective of treatment method. No mode of treatment or radiofrequency energy power setting resulted in full-thickness chondrocyte death. The depth of cartilage ablation was increased in the treated areas in contact mode in proportion to the power level and the time of treatment. No statistically significant difference in radiolabeled sulfate uptake of the specimens was observed with respect to the treatment modes and power settings. CONCLUSION: The extent of chondrocyte death by radiofrequency energy was not as significant as reported previously when the probe was moved at the speed of 10 mm/sec. Radiofrequency energy may be useful to treat chondromalacic cartilage in a contact mode using a proper energy level and delivery time.

BACKGROUND: PAD-SEARCH (Peripheral Arterial Disease-Screening and Evaluation of diabetic patients in Asian Regions Characterized by High risk factors) is the first international study to investigate the prevalence of peripheral arterial disease (PAD) in Asian type 2 diabetic patients and to demonstrate the relationships between the putative risk factors and PAD in this population. METHODS: A total of 6,625 type 2 diabetic patients (2,873 males and 3,752 females aged 50 and older) were enrolled in PAD-SEARCH in Korea, China, Taiwan, Hong Kong, Indonesia, Thailand and Philippines from October 2003 to March 2004. The Fukuda vascular profile VS-1000(TM) was used to determine the ankle-brachial index (ABI) and the brachial-ankle pulse wave velocity (baPWV). RESULTS: The mean patient age was 63.7 +/- 8.2 years and the mean duration of diabetes was 10.3 +/- 8.0 years. 1,172 (17.7%) subjects were diagnosed as PAD by the ABI (< or = 0.9). Subjects with PAD had a significantly longer duration of diabetes or hypertension, a higher HbA1c level and a significantly lower mean BMI than did the non-PAD subjects. In terms of the lipid profiles, triglyceride was the only significant variable. Notably, the mean ABI and baPWV in the females were significantly poorer than the age matched males for the in subjects with a normal ABI. However, the mean ABI and baPWV in males were significantly poorer than those of the age matched females for the subjects with PAD. On the multivariate analysis, gender, age, BMI, smoking status, duration of diabetes and a previous history of cerebrovascular disease were identified as the independent risk factors of PAD. CONCLUSION: These findings suggest that PAD is a common complication in Asian type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for Asian diabetic patients with high risk factors.

OBJECTIVES: This study was conducted to integrate the results of studies assessing the association between chronic noise exposure and blood pressure. METHODS: Using a MEDLINE search with noise exposure, blood pressure and hypertension as key words, we retrieved articles from the literature that were published from 1980 to December 1999. The criteria for quality evaluation were as follows: 1) the study subjects must have been workers employed at a high noise level area 2) The paper should use average and cumulative noise exposure as method for exposure evaluation. 3) Blood pressure in each article should be reported in a continuous scale Among the 77 retrieved articles, six studies were selected for quantitative meta-analysis. Before the integration of the regression coefficients for the association between blood pressure and noise level, homogeneity tests were conducted. RESULTS: All studies were a cross-sectional design and the study subjects were industrial workers. Five papers used a time-weighted average for noise exposure and only one paper calculated the cumulative noise exposure level. The measurement of blood pressure in the majority of studies were accomplished in a resting state, and used an average of two or more readings. The homogeneity of studies was rejected in a fixed effect model, so we used the results in a random effect model. The results of the quantitative meta-analysis, the weighted regression coefficient of noise associated with systolic blood pressure and diastolic blood pressure were 0.05 (95% confidence interval [CI]: -0.03, 0.13) and 0.06 (95% CI: -0.01, 0.13), respectively. CONCLUSIONS: Our results suggested that chronic exposure to industrial noise does not cause elevated blood pressure.

PURPOSE: This study was conducted to examine various clinical factors for their ablity to predict mortality in geriatric patients following trauma. METHODS: In this retrospective study, medical records from Chun Cheon Sacred Heart hospital were reviewed for patients 65 years and older who sustained trauma. The following variables were extracted and examined, independently and in combination, for their ablity to predict death: age, gender, mechanism of injury, blood pressure, and respiration, pulse rate, as well as Glasgow Coma Score, Revised Trauma Score, and Injury Severity Score. These patients had entered the hospital following trauma during a 2-year period (1999-2000). RESULTS: the Injury Severity Score (more than 28), the Glasgow Coma Score (less than 9), and the Revised Trauma Score (less than 8) were variables that correlated with mortality. Mortality rates were higher for men than for women. Admission variables associated with the highest risks of death included hypotension (mean blood pressure < 78 mmHg); pedestrian and motorcycle traffic accident; skull fracture, subdural hemorrhage, and diffuse axonal injury; and hemothorax and lung contusion. CONCLUSION: Admission variables in geriatric trauma patients can be used to predict the outcome and may also be useful in making decisions about triage, and treatment of the patient.
