Purpose: We analyzed the efficacy and safety of extracorporeal shock wave lithotripsy (ESWL) for treating patient with urinary tract calculi with using a Dornier Compact S(R)lithotriptor. Materials and Methods: We retrospectively reviewed the records of all the patient who had urinary calculi and who were treated by ESWL between August 1, 1996 and August 1, 2001. The location and sizes of the stones, the number of sessions, the success rate, the causes of failure and the complications of ESWL were analyzed. The definition of successful treatment was no calcification on the X-ray (plain film, KUB) or residual fragments < or= 3mm in size. Results: Of the 470 cases, there were 157 (33.4%) and 313 (66.6%) cases of renal stones and ureteral stones, respectively. The total success rate was 94.3% (445/470), with success rates of 97.4%, 90.8%, 82.1% and 88.9% for stone sized <10mm, 11-20mm, 21-30mm and >31mm, respectively. Conclusions: The results showed that ESWL is a highly effective and minimally invasive treatment modality as the 1st therapeutic option for urinary stones. The Dornier Compact S(R)is an efficient and safe lithotripter that's capable of treating stones in the kidney and throughout the ureter.

PURPOSE: Breast cancer is second most common cancer in women. Most of the patients with breast cancer treated with mastectomy take breast reconstruction. Nipple reconstruction is an important step in breast reconstruction. Many surgeons have investigated of nipple reconstruction using the flap technique after breast reconstruction with the autologous tissue. The objective of this study is to evaluate the results of nipple reconstruction using the C-V flap technique after breast reconstruction only with the breast expander. METHODS: From April 2006 to May 2008, the authors treated 17 patients of nipple reconstruction using C-V flap technique, who received breast reconstruction only with the breast expander. As we have predicted decrease in the size of reconstructed nipple, we designed flap a little larger than wanted nipple size. Nipple splint was applied for 4-6 months for minimizing decrease of the size of reconstructed nipple. The diameter and height of the reconstructed nipple were measured and patient's satisfaction score was assessed. RESULTS: Mean follow-up duration was 12.5 months. Among the 17 patients, the average absorption rate by height of nipple was 47.0%. Partial necrosis was noted in 1 case, and treated well with conservative management. There were no other significant complications noted. Patient's satisfactory score was assessed by the height, design and location of the nipple. The average of satisfaction score was 85%, 68%, 62% and total average was 83%. CONCLUSION: The authors experienced 17 patients of nipple reconstruction using the C-V flap technique after breast reconstruction only with the breast expander. The absorption rate of the size of the nipple, complications and patient's satisfactory score of this study were similar to those of nipple reconstruction after breast reconstruction with the autologous tissue. It is expected that nipple reconstruction after breast reconstruction only with the breast expander is safe and reliable. It is considered that a long-term study is necessary.

PURPOSE: Pseudohypoparathyroidism is a hereditary disorder characterized by symptoms and signs of hypoparathyroidism, typically in association with distinctive skeletal and developmental defects. Hypoparathyroidism is caused by a insufficient end-organ response to PTH (parathyroid hormone). Hypoparathyroidism consists of four types in which the most common form, pseudohypoparathyroidism-Ia, accompany with Albright's hereditary osteodystrophy. We experienced a case of a woman who had been suffering from calcified mass on left foot, diagnosed Albright's hereditary osteodystrophy. METHODS: We present a case of a 24-year-old Korean female who visited plastic surgery department with a painful mass on dorsum of the left foot. On the physical exam, bony hard and painful mass, fixed to dermis, was noted. Plain X-ray films demonstrate suspicious calcification on subcutaneous tissue of dorsum of the left foot. The patient was diagnosed pseudohypoparathyroidism 2 years ago at the plastic surgery department. At the visiting time, the laboratory results were within normal range even though the patient actually had a disease. The reason is because the patient has been treated with Vit.D, calcium replacement therapy and thyroid hormone therapy. Moreover, the patient has been treated with anticonvulsant agents due to epilepsy. On the brain computer tomography (CT), calcification was noted on the basal ganglia and dentate nucleus. So we decided the total excision of entire mass from the left foot. RESULTS: We excised main mass with numerous pinhead sized masses which were scattered around the main mass. The 6.0x4.0x0.5 cm sized main mass was bony hard, and its surface was flat and margin was irregular. The permanent biopsy was confirmed that the main mass and all the scattered tiny masses were heterotopic calcification. The patient did not suffer from the pain after the mass excision. The wound has been healed without any problem. CONCLUSIONS: Heterotrophic calcification is often accompanied with pseudohypoparathyroidism, but such a huge one is uncommon. We report a case of pseudohypoparathyroidism with heterotrophic calcification developed in dorsum of left foot who was diagnosed by excisional biopsy.

PURPOSE: Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice in treating osmidrosis for several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or the possibility of hematoma and scars have occurred frequently. So we used XPS(R) microresector(Shaver) in procedure which requires removal of soft tissue for comparing results between surgical excision and the laters. METHODS: From January 2007 to February 2008, a total of 20 patients(8 male and 12 female) underwent XPS(R) microresector(Shaver) assisted aspiration for treating osmidrosis. The mean age of the subjects was 21.9, and we tried to analyze some advantages of XPS(R) microresector(Shaver). RESULTS: The average operation time was 61.6 minutes. This results can show that the patients who received XPS(R) microresector(Shaver) assisted aspiration can accomplish better outcomes than any other procedures in terms of operation time at least. Moreover, no significant postoperative complications occurred in our studies. Subjects have been followed up from 2 months to 1 year and among these patients, no one suffered from critical complications. CONCLUSION: In brief, XPS(R) microresector(Shaver) is able to shorten the time of operation and simplify the procedures relatively and this device has more superiorities in wound healing by maintaining of vascularized dermal skin flaps. It means that XPS(R) microresector (Shaver) can prevent flap necrosis, axillary hair loss and minimalize scarring and bleeding. Thus, we expect that these advantages can lead to better patient's comfort and self-confidence than several previous procedures.

PURPOSE: Gynecomastia is an abnormal increase in the volume of the male breast. Subcutaneous mastectomy was the first surgical treatment for gynecomastia. But because of the complications such as nerve injury and scar formation, subcutaneous mastectomy has been substituted with liposuction. Recently various techniques including ultrasound-assisted liposuction has been used for treatment of gynecomastia. The purpose of this study is to evaluate the results of XPS(R) microresector (Shaver) for treatment of gynecomastia. METHODS: 17 patients, 33 breasts of gynecomastia, Simon grade I or II have been treated with XPS(R) microresector (Shaver). The mean age was 24.5. The subcutaneous tissue and glandular tissue were removed with XPS(R) microresector (Shaver). The operation time, the weight of removed tissue and patients' satisfaction score were accessed. RESULTS: The mean operation time was 78.2 minutes. The mean weight of removed tissue was 113.8 g. There were no significant complications such as necrosis, hematoma, infection or scar contracture. Patients' satisfactory score of scar, shape and confidence were 8.4, 8.2 and 8.4 respectively. As the average score was 8.3, most of the patients were satisfied with their breasts. CONCLUSION: The authors have treated 17 patients suffering from gynecomastia with XPS(R) microresector (Shaver). We obtained short operation time, early recovery, minimal operative scar and less complications with XPS(R) microresector (Shaver) for the treatment of gynecomastia, and patients were satisfied with the results of our method. We concluded that XPS(R) microresector (Shaver) is an alternative option for the treatment of gynecomastia.

To investigate the significance of precordial ST-segment depression in acute inferior myocardial infarction, electrocardiographic findings in 51 consecutive patients with acute inferior myocardial infarction were analysed with clinical findings and coronary artery angiography. Thirty patients(Group A) had no or <1.0mm ST depression, and twenty one patients(Group B) had > or =1.0mm ST depression in two or more precordial(VI-6) leads were included in this study. Patients in Group B thd greater summed ST-segment elevation in leads II, III, AVF(6.3+/-6.1 vs 2.4+/-2.3mm, p<0.05), higher plasma peak CK levels(1776.8+/-1503.3 vs 5666.6+/-587.7 IU/L, p<0.05), higher plasmal peak CK-MB levels(141.2+/-1553.3 vs 34.1+/-35.7 IU/L, p<0.05), more prevalence of proximal left anterior descending coronary artery disease (46.6% vs 16.6%, p<0.05) than patients in Group A. There was no significant difference between Group A and Group B in the LV ejection fraction, delta area decreasing rate, infarction related asynergy, complications during hospitalization and cardiac events during follow up period. In conclusion, patients with acute inferior myocardial infarction who have associated with precordial ST depression had more extensive myocardial damage probably due to concomitant left anterior descending coronary artery disease.

Renal cell carcinoma (RCC) is one of the most malignant tumors in urology, and due to its insidious onset patients frequently have advanced disease at the time of clinical presentation. Thus, early detection is crucial in management of RCC. To identify tumor specific proteins of RCC, we employed proteomic analysis. We prepared proteins from conventional RCC and the corresponding normal kidney tissues from seven patients with conventional RCC. The expression of proteins was determined by silver stain after two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). The overall protein expression patterns in the RCC and the normal kidney tissues were quite similar except some areas. Of 66 differentially expressed protein spots (p<0.05 by Student t-test), 8 different proteins from 11 spots were identified by MALDI-TOF-MS. The expression of the following proteins was repressed (p<0.05); aminoacylase-1, enoyl-CoA hydratase, aldehyde reductase, tropomyosin alpha-4 chain, agmatinase and ketohexokinase. Two proteins, vimentin and alpha-1 antitrypsin precursor, were dominantly expressed in RCC (p<0.05).

Trismus is a common problem to most people experiencing at once in his or her life and to most dental practitioners experiencing frequently. It has a number of potential causes which are single factor or complex factors. Its treatment will depend on the cause. The purpose of this study was to discuss the causes of trismus condition and the various treatments available. This study was made by reviewing of collected data from 86 patients complained of trismus among patients who were diagnosed by TMD, tumor, infection including tetanus, soft tissue anomalies, bony fracture and ankylosis from Jan 2002 to Dec 2004 on department of oral and maxillofacial surgery at Pusan National University Hospital, South Korea. The clinical reviews regarding chief complaints, clinical characteristics, diagnostic examination, treatments and the results on the patients were given as follows. 1. The etiology of trismus commonly were derived from temporomandibular joint(TMJ) disorder, TMJ ankylosis, TMJ tumor, odontogenic maxillofacial infection, mandibular condylar fracture, tetanus. 2. The chief complaints of trismus patients were progressive mouth opening limitation, TMJ pain, malocclusion, facial asymmetry, retrognathic state. 3. Especially, for the differential diagnosis between the fibrous ankylosis and true bony ankylosis, computed tomogram (CT) was useful. Surgical gap arthroplasty on bony ankylosis patients was applied and the gain of mouth opening after operation was average 35.8 mm during 19 months. 4. The tetanus, rarely, also induced the trismus with the range of mouth opening less than 10 mm. The average serum level of tetanus anti-toxin was 0.02-0.04 IU/mL. The limitation of mouth opening was improved into average 38 mm on 4 weeks after injection of 10,000 units of tetanus immune globulin. 5. In the treatment of osteochondroma, TMD, odontogenic infection and fracture, and the others inducing trismus, to obtian the maximum result and decreased inadequate time and effort, it is important to finding the causes from the exact clinical examination and diagnosis.

BACKGROUND AND OBJECTIVES: This trial evaluated the safety and efficacy of the Genoss drug-eluting coronary stent. METHODS: This study was a prospective, multicenter, randomized trial with a 1:1 ratio of Genoss drug-eluting stent (DES)™ and Promus Element™. Inclusion criteria were the presence of stable angina, unstable angina, or silent ischemia. Angiographic inclusion criteria were de novo coronary stenotic lesion with diameter stenosis >50%, reference vessel diameter of 2.5–4.0 mm, and lesion length ≤40 mm. The primary endpoint was in-stent late lumen loss at 9-month quantitative coronary angiography follow-up. Secondary endpoints were in-segment late lumen loss, binary restenosis rate, death, myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and stent thrombosis during 9 months of follow-up. RESULTS: We enrolled 38 patients for the Genoss DES™ group and 39 patients for the Promus Element™ group. In-stent late lumen loss at 9 months was not significantly different between the 2 groups (0.11±0.25 vs. 0.16±0.43 mm, p=0.567). There was no MI or stent thrombosis in either group. The rates of death (2.6% vs. 0%, p=0.494), TLR (2.6% vs. 2.6%, p=1.000), and TVR (7.9% vs. 2.6%, p=0.358) at 9 months were not significantly different. CONCLUSION: This first-in-patient study of the Genoss DES™ stent showed excellent angiographic outcomes for in-stent late lumen loss and major adverse cardiac events over a 9-month follow-up.
