A randomized, prospective study was conducted between October, 1994 and April, 1996 to compare the efficacy and safety of warfarin (group I) with dextran (group II) for the prevention of DVT after hip arthroplasty. 109 cases in 106 patients were included in the study. There were 60 cases in group I and 49 cases in group IL Risk factor for DVT were analysed before surgery and prophylactic modalities were performed. Color doppler was performed to all patients by one muskuloskeletal radiologist on 5th 8th post operative day and on 6 weeks after operation. DVT occurred in ten ( 16.6% ) of the 60 patients in group I, six ( 12.2% ) of the 49 patients in group II. but, this difference was not significant ( p= 0.582 ). Statistical analysis for the risk factors of age, sex, operation time, anesthetic method and operation method were performed and there were no statistical difference. Only statistical significance was a higher rates of DVT in cemented hip arthroplasty (p=0.028). There were seven proximal thigh DVT and nine calf DVT. We confirmed with sequential color doppler image that all cases of DVT except two complicated cases were resolved within 8 weeks after treatment: one case was expired for the reason of PE, and the other case had thigh hematoma during the treatment with warfarin. We could detect only one case of late onset DVT.

OBJECTIVE: 6-Gingerol, one component of ginger (Zingiber officinale) compound, has been known to possess anti-inflammatory, analgesic, anti-emetic, and anti-cancer effects. In this study, the apoptotic ability of 6-gingerol was investigated in human prostate cancer cells. METHODS: 3-(4,5-Dimethylthiazol-2-yl)- 2,5-diphenyl-tetrazolium bromide (MTT) assay, flow cytometry, and western blot analysis were done in LNCaP human prostate cancer cell lines treated with the various doses of 6-gingerol for the different durations of drug exposure. RESULTS: 6-Gingerol in doses ranging from 100 to 300 microM induced dose- and time-dependent inhibition of cell viability in prostate cancer cells by using MTT assay. Maximal inhibition of cell viability was observed at 300 microM of 6-gingerol for 48 hours treatment in LNCaP cells. 6-Gingerol at the dose of 100 microM did not produce any significant change in apoptotic cells in flow cytometry analysis. However, significant increase in sub-G0/G1 phase was observed in cells treated with 200 and 300 microM of 6-gingerol. Any significant cell cycle arrest was not induced by 6-gingerol. In western blotting analysis, expression of caspase-3 was not evident in cells treated with 6-gingerol for 24 hours. However, 48 hours treatment with 6-gingerol altered the expression of caspase-3 in LNCaP cells. Expression of cleaved poly showed the dose-dependent fashion in both 24 hours and 48 hours treatment of 6-gingerol. CONCLUSION: These observations suggest that 6-gingerol may induce apoptosis in LNCaP human prostate cancer cells.

PURPOSE: Although muscle hernia has been well described in the lower-extremity, muscle hernias in the upper extremity are extremely rare. As with lower extremity muscle hernias, the forearm muscle hernia may result from forced exertion of strenuous activity or following blunt trauma. The objective of this paper is to report an extraordinary case of forearm muscle hernia after radial forearm sensory tendocutaneous free flap with references. METHODS: A 58-year-old male patient received wide excision and radical neck dissection and lower lip reconstruction with radial forearm sensory tendocutaneous free flap for squamous cell cancer on the lower lip. 16 weeks after the operation, he complained of protruding mass on the forearm and the size was increasing. In postoperative 18 weeks, MRI showed herniation of flexor digitorum superficialis. For unaesthetic cause and preventing progress, the authors performed direct fascial closure and Mesh graft. RESULTS: In 12 months after the surgery there was no recurrence and the patient remained symptom-free. CONCLUSION: Pain on extremity exertion and unaesthetic buldge of forearm due to forearm muscle hernia were the primary indications for surgery which consist of direct closure, fasciotomy, fascia lata onlay graft, fascia lata inlay graft, etc. The authors experienced uncommon forearm muscle hernia after radial forearm free flap and satisfying result of treatment.

PURPOSE: Predicting the change in breast size for a specific patient's need is a challenging problem in breast augmentation. We intended to investigate the post-augmentation degree of breast size according to the size of cohesive silicone gel implant. METHODS: To predict post-augmentation breast size, we measured 100 patients' pre-and postoperative 3 month's bust circumference. All patients were performed by total subfascial breast augmentation with moderate profile cohesive silicone gel implant through areolar omega (transareolar-perinipple) incision. RESULTS: According to this study, each additional one pair of 100mL in implant size yielded an approximate 1.5cm increase in bust circumference(p=0.006). CONCLUSION: From this result, we conclude that each additional one pair of 100mL in implant volume yielded about 1.5cm increase in bust circumference. Although this result may not be applied to every patient, we believe that it yields a practical chart that can help to predict the amount of increase in breast size with the use of cohesive silicone gel implant of a specific size preoperatively.

Purpose: The transforming growth factor-beta (TGF-beta) is a peptide that has diverse biologic actions in human tissue and is thought to contribute to tumor development and progression. Increased TGF-beta1 levels were found in several types of malignant tumors. TGF-beta1 expression in RCC and adjacent normal kidney tissues was examined to determine the TGF-beta1 in renal cell carcinoma (RCC). MATERIALS AND METHODS: The TGF-beta1 protein levels in cancer and a normal portion of a specimen were analyzed in 61 radical nephrectomized clear cell type RCC by an enzyme-linked immunosorbent assay (ELISA), with the results compared with the clinicopathological characteristics. Immunohistochemical staining was performed to localize their expression. RESULTS: Compared with non-tumor kidney specimens, primary renal cell carcinoma demonstrated a significantly higher TGF-beta1 protein level (p<0.001). There were significant differences in the TGF-beta1 level among the histological grade (p<0.01). The tissue TGF-beta1 level was the highest in T4 stage, but there was no statistical significance between the T stages. Immunohistochemical analysis demonstrated that TGF-beta1 was localized to the tumor cytoplasm and their intensity reflected the protein expression level in these tissues. CONCLUSIONS: These results suggest that enhanced TGF-beta1 expression contributes to carcinogenesis and tumor progression in the later stages of renal cell carcinoma.

PURPOSE: An experience of extracorporeal shock wave lithotripsy (ESWL) using the Piezolith 2300 lithotriptor in 2077 (2223 renal units) patients with urinary tract calculi is presented. MATERIALS AND METHODS: The records of 2077 patients who underwent an ESWL between April 1990 and March 2001 were reviewed retrospectively. The ESWL treatment sessions, success rate, auxiliary procedures, and complications according to the stone size and location were analyzed. RESULTS: Of 2223 renal units (2077 patients), 781 (35.1%) had renal, 1150 (51.7%) had ureteral and 292 (13.2%) had multiple stones. Of these cases 1116 (50.2%) had stones <1cm in size, 805 (36.2%) had stones ranging from 1 to 2cm in size, 194 (8.7%) had stones ranging from 2 to 3cm in size and 108 (4.9%) had stones ranging larger than 3cm in size, including staghorn or multiple stones. The success rate ranged from 96.3% for stones <1.0cm in diameter to 41.7% for stones >3.0cm in size, with an 86.4% overall success rate. For auxiliary measures, the push back procedure was done in 23 cases. The treatment modalities of the unsuccessful cases were open surgery in 95 cases and ureteroscopic stone removal in 31. A stone street developed in 93 patients. However, there were no other significant complications. CONCLUSIONS: Extracorporeal shock wave lithotripsy with a piezolith 2300 lithotriptor is to be a safe and efficient outpatient procedure for the initial treatment of properly selected urinary tract calculi.

PURPOSE: As a rare congenital anomaly, Poland's syndrome has been known to show hypoplasia in breast and nipple, absence of pectoralis major muscle, and aplasia or deformity of rib or costal cartilage which has been reported to be more common in male. However, most patients who are seeking operation are female patients having one-side deformity. In the field of plastic surgery, the major surgical indications could be asymmetric chest wall depression in man or breast hypoplasia in woman. There are many reconstruction options according to the degree of patient's deformity: a prosthetic implant, breast implant with or without tissue expander, latissimus dorsi musculocutaneous pedicled flap with or without implant and/or tissue expander, and free tissue transfer with or without tissue expander. METHODS: The authors have treated 4 patients(2 male, 2 female) who had a diagnosis of Poland's syndrome. According to the degree of patient's deformity, all patients underwent correction of breast asymmetry and unilateral anterior thoracic hypoplasia with one-staged or two-staged reconstruction. RESULTS: All patents were satisfied with the results and there occurred no specific complications. CONCLUSION: The authors propose the treatment plan for patient with Poland's syndrome, according to the degree of patient's deformity. In case of male patient with mild deformity, the prosthetic implant or latissimus dorsi musculocutaneous pedicled flap will simulate the missing pectoralis and improve the contour deformity. In case of female patient with moderate to severe breast asymmetry and upward displaced nipple areolar complex (NAC), NAC can be lowered with tissue expander, breast can be enlarged with autologous free flaps or latissimus dorsi musculocutaneous pedicled flap with implant.

BACKGROUND: This study was performed to evaluate the effects of intercostal nerve block added in intravenous patient-controlled analgesia (IV-PCA; PCA) on pain, pulmonary function and the movement of the ipsilateral arm after a thoracotomy. METHODS: Forty five patients undergoing elective thoracotomy were randomly allocated into one of three groups. The groups were divided as follows: PCA, ICB-PCA (PCA and intercostal nerve blocks by direct injection of 5 ml of 0.2% bupivacaine into the intercostal spaces of two upper and two lower segments around the surgical incision) and IM groups. For the PCA, the patients that received PCA, were administered IV bolus of 0.1 mg/kg of nalbuphine followed by PCA with 0.1% nalbuphine (basal rate 0.5 ml/hr, bolus dose 1 mg and lockout interval 8 minutes). In each group, VAS score, the inspiratory capacity and the movement of the ipsilateral arm were checked postoperatively at 6, 24, 48 and 72 hours. RESULTS: Inspiratory capacity was decreased less in ICB-PCA group (P<0.05) at 6 hour, but after 24 hour, there were no differences between the groups. The analgesic effect was significantly better in ICB-PCA group as compared to the PCA or IM groups (P<0.05). Furthermore, arm motion limitation after operation was the least in ICB-PCA group (P<0.01). CONCLUSION: Intraoperative intercostal nerve blocks added in PCA has a transient improvement of pulmonary function, and also provide better analgesia and improved ipsilateral arm motion after a thoracotomy than in PCA or IM analgesia. The authors recommend adding intercostal nerve block for patients undergoing thoracotomy who receive IV-PCA.
