OBJECTIVE: The purpose of this study was to understand the differences in masseter muscle (MM) between the shifted and non-shifted sides in facial asymmetry patients, and the changes shown by MM after mandibular surgery. METHODS: Pre- and post-operative CT scans were performed on 12 Class III patients with facial asymmetry who were treated by intraoral vertical ramus osteotomy and 10 subjects with normal occlusion. Using the V-works 4.0 program (Cybermed, Seoul, Korea), 3-dimensional images of the mandible, and MM were reconstructed, and evaluated. RESULTS: In the asymmetry group, the MM angle between the shifted and non-shifted sides was only significantly different (p < 0.05). Compared with normal occlusion, the asymmetry group showed a significantly smaller volume and maximum cross-sectional area in both sides of MM (p < 0.05). After mandibular surgery, the angle of MM (p < 0.01) and differences in angle between the shifted and non-shifted sides of MM (p < 0.05) were significantly decreased. The thickness in the maximum cross-sectional area was significantly increased (p < 0.01). After surgery, MM in facial asymmetry patients was similarly changed to those in the normal occlusion group except for widths. CONCLUSIONS: MM in facial asymmetry was definitely different from those in normal occlusion. However, this study suggests that MM changed symmetrically in conjunction with the mandible after proper mandibular surgery.

PURPOSE: The aim of this study was to evaluate the results of multiplex polymerase chain reaction (PCR) in patients with chronic pelvic pain syndrome (CPPS) and the significance of microorganisms as the causative factor of CPPS. MATERIALS AND METHODS: We evaluated the frequency of 19 possible causative microorganisms of prostatitis in 849 patients who had prostatitis symptoms from April 2007 to March 2009 by using multiplex PCR. All of the enrolled patients were category III by the definition of the NIH Chronic Prostatitis Workshop. RESULTS: Of the 849 patients, 414 (49%) and 435 (51%) were categories IIIa (inflammatory CPPS) and IIIb (noninflammatory CPPS). On multiplex PCR, using the third voided urine specimen (VB3), 369 (89%) of the 414 category IIIa and 367 (84%) of the 435 category IIIb cases were found to have positive PCR results for causative microorganisms. The common microorganisms were Enterococcus, Ureaplasma urealyticum, Lactobacillus, Streptococcus agalactiae, and Chlamydia trachomatis in 173 (18%), 144 (15%), 129 (13%), 78 (8%), and 69 cases (7%), respectively. CONCLUSIONS: There were too many positive PCR results for causative microorganisms in the CPPS patients despite negative urine culture examination. Therefore, it is necessary to rule out contamination of the specimen to achieve reliable results with multiplex PCR. However, multiplex PCR can detect various unknown microorganisms suggestive of the etiology of CPPS, particularly those that are difficult to cultivate. PCR is expected to play an important role in the diagnosis of CPPS, but further studies will be required to define the usefulness of molecular tests.

In order to provide some clues for differential diagnosis of trematode infections in fecal examination, the comparative morphology of eggs of 5 kinds of heterophyid flukes (Metagonimus yokogawai, Heterophyes heterophyes nocens, Heterophyopsis continua, Stellantchasmus falcatus and Pygidiopsis summa) and Clonorchis sinensis was studied. The eggs were obtained from distal portion of uteri of worms which were recovered from men after treatment. The characteristic shape and apperance of each kind of eggs were observed in detail under light microscope, and their length and width measured and compared one another. The results are as follows: Eggs of C. sinensis are elongated ovoidal in shape with attenuated anterior end, 25.3-33.2 (28.3 in average) micrometer long and 14.2-17.4(15.9) micrometer wide with length /width ratio of 1.60-2.00 (1.78). They differ from all heterophyid eggs in that they have prominent wrinkling (muskmelon pattern) at their shell surface. P. summa eggs are ovoid to pyriform in shape and characterized by the smallest size of all kinds examined, 19.8-22.9(21.6) micrometer long and 11.1-13.4 (12.1) micrometer wide and the ratio 1.63-1.99 (1.78). Eggs of S. falcatus are elongated ovoidal and most slender form, 25.3-29.2 (27.2) micrometer long and 11.1-13.4 (12.5) micrometer wide with the ratio of 2.00-2.57 (2.17). Eggs of M. yokogawai are ellipsoid to elliptical in shape with round both ends, 26.9-31.6 (28.5) micrometer long and 14.2-18.2 (16.8) micrometer wide with the ratio of 1.48-2.11(1.70). H. continua eggs are oval in shape, sometimes similar to M. yokogawai or H. h. nocens eggs, however, the relative breadth is broadest among all kinds, with maximum width at posterior half portion. They are 23.7-27.7 (25.0) micrometer long, 15.8-18.9 (16.4) micrometer wide with the ratio of 1.33-1.75 (1.53). Eggs of H. h. nocens are ellipsoid to ovoid in shape but sometimes more slender than M. yokogawai and have slightly pointed both ends. They are 23.7-29.2 (25.7) micrometer long, 14.2-15.8 (15.4) micrometer wide, and the ratio 1.50-2.06 (1.67). From the results, it is concluded that eggs of 5 kinds of heterophyids and C. sinensis can be morphologically differentiated one another, however, careful observation and measurement on sufficient number of eggs are needed.

OBJECTIVE: The aim of this study was to evaluate effect of pulsed radiofrequency (PRF) neuromodulation of suprascpaular nerve (SSN) in patients with chronic shoulder pain due to adhesive capsulitis and/or rotator cuff tear. METHODS: The study included 11 patients suffering from chronic shoulder pain for at least 6 months who were diagnosed with adhesive capsulitis (n=4), rotator cuff tear (n=5), or adhesive capsulitis+rotator cuff tear (n=2) using shoulder magnetic resonance imaging or extremity ultrasonography. After a favorable response to a diagnostic suprascapular nerve block twice a week (pain improvement >50%), PRF neuromodulation was performed. Shoulder pain and quality of life were assessed using a Visual Analogue Scale (VAS) and the Oxford Shoulder Score (OSS) before the diagnostic block and every month after PRF neuromodulation over a 9-month period. RESULTS: The mean VAS score of 11 patients before PRF was 6.4+/-1.49, and the scores at 6-month and 9 month follow-up were 1.0+/-0.73 and 1.5+/-1.23, respectively. A significant pain reduction (p<0.001) was observed. The mean OSS score of 11 patients before PRF was 22.7+/-8.1, and the scores at 6-month and 9 month follow-up were 41.5+/-6.65 and 41.0+/-6.67, respectively. A significant OSS improvement (p<0.001) was observed. CONCLUSION: PRF neuromodulation of the suprascapular nerve is an effective treatment for chronic shoulder pain, and the effect was sustained over a relatively long period in patients with medically intractable shoulder pain.

BACKGROUND: Adipose tissue damage of cryopreserved fat after autologous fat transfer is inevitable in several processes of re-transplantation. This study aims to compare and analyze the survivability of adipocytes after thawing fat cryopreserved at -20degrees C by using thawing methods used in clinics. METHODS: The survival rates of adipocytes in the following thawing groups were measured: natural thawing at 25degrees C for 15 minutes; natural thawing at 25degrees C for 5 minutes, followed by rapid thawing at 37degrees C in a water bath for 5 minutes; and rapid thawing at 37degrees C for 10 minutes in a water bath. The survival rates of adipocytes were assessed by measuring the volume of the fat layer in the top layers separated after centrifugation, counting the number of live adipocytes after staining with trypan blue, and measuring the activity of mitochondria in the adipocytes. RESULTS: In the group with rapid thawing for 10 minutes in a water bath, it was observed that the cell count of live adipocytes and the activity of the adipocyte mitochondria were significantly higher than in the other two groups (P<0.05). The volume of the fat layer separated by centrifugation was also measured to be higher, which was, however, not statistically significant. CONCLUSIONS: It was shown that the survival rate of adipocytes was higher when the frozen fat tissue was thawed rapidly at 37degrees C. It can thus be concluded that if fats thawed with this method are re-transplanted, the survival rate of cryopreserved fats in transplantation will be improved, and thus, the effect of autologous fat transfer will increase.

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions.

BACKGROUND: Liposuction is a procedure to reduce the volume of subcutaneous fat by physical force. Intracellular storage fat is composed of triglyceride, whereas circulating fat particles exist as cholesterol or triglycerol bound to carrier proteins. It is unavoidable that the storage form of fat particles enters the circulation system after these particles are physiologically destroyed. To date, however, no studies have clarified the fatal characteristics of fat embolism that occurs after the subclinical phase of free fat particles. METHODS: A mixture of human lipoaspirate and normal saline (1:100, 0.2 mL) was injected into the external jugular vein of rats, weighing 200 g on average. Biopsy specimens of the lung and kidney were examined at 12-hour intervals until postoperative 72 hours. The deposit location and transport of the injected free fat particles were confirmed histologically by an Oil Red O stain. RESULTS: Inconsistent with previous reports, free fat particles were transported from the intravascular space to the parenchyma. At 24 hours after infusion, free fat particles deposited in the vascular lumen were confirmed on the Oil Red O stain. At 72 hours after infusion, free fat particles were accumulated compactly within the parenchymal space near the perivascular area. CONCLUSIONS: Many surgeons are aware of the fatal results and undiscovered pathophysiologic mechanisms of free fat particles. Our results indicate that free fat particles, the storage form of fat that has been degraded through a physiological process, might be removed through a direct transport mechanism and phagocytotic uptake.
