PURPOSE: This study was to measure the angle between the femoral epicondylar axis and the femoral posterior condylar axis, to clarify which axis can be used as a guideline to achieve proper rotational align- ment of femoral component in total knee arthroplasty. MATERIAL AND METHODS: From Jan. 1997 to Dec. 1998, the axial images of MRI of 121 patients who sustained acute knee injury were selected to measure the posterior-epicondylar angle(the angle between the femoral epicondylar axis and the femoral posterior condylar axis). Congenital anomaly or any fracture cases were all excluded. Comparisons were made according to gender and ages and the student t-test was used to evaluate the statistical differences. RESULTS: The mean posterior-epicondylar angle was a 4.8(+- 2.0) and there was no significant statisti- cal difference between gender and ages except 3rd decade. CONCLUSION: It can induce an insufficient external rotation of the femoral component in total knee arthroplasty, if we usually do 3 of external rotation of femoral component from the posterior condylar axis.

BACKGROUND: Regional anesthesia for cesarean section is associated with a high incidence of nausea and/or vomiting (N&V) during the operation. Metoclopramide and droperidol have been known to be effective in the prevention of N&V. However, they have been reported to induce some adverse effects such as sedation. We evaluated the efficacy of metoclopramide and droperidol in the prevention of N&V in spinal and epidural anesthesia for cesarean section. METHODS: A prospective randomized double-blind study was performed on 180 parturients scheduled for elective cesarean section. They were allocated into spinal or epidural (n = 90, each) anesthesia groups and each group into either a placebo, metoclopramide, or droperidol drug group (n = 30, each). After delivery, 2 ml saline, 10 mg metoclopramide, or 0.625 mg droperidol was given to the parturients, respectively. Incidences of N&V and sedation during the operation were checked, and the other adverse effects of the anesthesias such as hypotension and visceral pain were compared among the groups. The height of sensory blockade was also checked. RESULTS: Epidural anesthesia was more related with N&V than spinal (P = 0.030). Among the groups there was a significant difference in the incidence of N&V (P = 0.002). There were fewer parturients with N&V in the droperidol group than in the placebo group during epidural anesthesia (P = 0.021). During both spinal and epidural anesthesia more parturients in the droperidol group had sedation than placebo or metoclopramide groups (P = 0.0001) and more in the metoclopramide group than in the pacebo group (P = 0.01). No differences were found in incidences of hypotension and in the height of sensory block among the groups. There were more parturients with visceral pain during epidural anesthesia (P = 0.031). CONCLUSIONS: Epidural anesthesia provoked N&V more frequently than spinal anesthesia for cesarean section. Only droperidol was effective in the prevention of N&V during epidural anesthesia, but had a more sedative effect than metoclopramide during either spinal or epidural anesthesia.

Malignant chondroid syringoma, previously called "mixed tumor of the skin of the salivary gland type"is a fairly uncommon type of sweat gland tumor. Malignant chondroid syringoma frequently arises from the trunk and extremities, whereas the benign tumor is common to the head region. The present case occurred in a female. The malignant nature of the tumor was evident from repeated recurrences after excision of the mass and histopathological study. Lack of response to radiotherapy and chemotherapy led to widespread metastasis. We report a case of malignant chondroid syringoma with lung metastasis in a 39-year-old female patient and response to chemotherapy. We also reviewed the literatures of malignant chondroid syringoma.

There are several rnethods to correct the tibial bony defect including resection, cement filling, autograft or allograft and metal augmentation. The purpose of this study is to find the adequate treatment method of tibia bony defect through analysis of the result with above methods. From Sep. 1993 to Dec. 1997, the authors analyzed 93 cases of tibial medial bony defect corrected by overresection of lateral condyle, allograft and metal wedge or block among 358 cases of primary total knee arthroplasty(TKA) operated at Asan Medical Center. All cases were devided into four groups according to the treatment method; group A(31 cases) with overresection of lateral condyle, group B(37 cases) with metal wedge, group C(21 cases) with metal block and group D(4 cases) with allograft. The mean follow up period was 23.6 months(12 56 months). The results were as follows, 1. There were no definite statistical difference between group A, B, C and D in HSS knee score, ROM, correction of deformity. But in group D, there is one case of loss of the correction. 2. Loosening of the implant was not noted, but 17 cases of mild bony resorption was found just beneath the implant. It was particularly prominent in group B(9 cases) than group A(5 cases) and C(3 cases). 3. Among 4 cases of allograft, one has developed collapse of allograft. 4. 3 cases of deep infection developed only in group C, which were followed by revision TKA. Although further follow up study should be carried out, we concluded that resection of lateral tibial condyle, allograft, metal augmentation is a good substitute to the correction of the tibial bony defect in primary TKA.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

Polyorchidism is a rare anomaly. It may result from transverse division of the urogenital ridge, a hypothesis that best explains the anatomical features of the supernumerary testicle. Until recently, histology provided the only proof of polyorchidism but new imaging techniques, such as sonography and magnetic resonance imaging(MRI), allows a highly accurate diagnosis of supernumerary testes rendering biopsy unnecessary. We report a case of polyorchidism in a 24 month-old-boy in whom the scrotal sonogram and magnetic resonance imaging confirmed the presence of 2 testicles without any evidence of tumor within his right hemiscrotum and who was treated conservatively and followed up 2 years.

Local infiltration in surgical wounds can reduce postoperative pain with very few side effects. We experienced two cases of chronic pain after forehead lift surgery. A 41-year-old male patient was suffering from a headache at the crown of the head and pain from the posterior neck. A 54-year-old female patient had pain around the forehead, worsened by psychological stress. They underwent forehead lift surgery 10 years and 8 months ago, respectively. Conservative treatments such as medication and physical therapy were not effective. After wound infiltration with 1% lidocaine more than ten times, pain significantly resolved in both patients.

BACKGROUND: Stellate ganglion block is usually performed at the transverse process of C6, because the vertebral artery is located anterior to the transverse process of C7. The purpose of this study is to estimate the location of the transverse process of C6 using the cricoid cartilage in the performance of stellate ganglion block. METHODS: We reviewed cervical lateral neutral-flexion-extension views of 48 patients who visited our pain clinic between January and June of 2010. We drew a horizontal line at the surface of the cricoid cartilage in the neutral and extension views of cervical lateral x-rays. We then measured the change in the shortest distance from this horizontal line to the lowest point of the transverse process of C6 between the neutral and extension views. RESULTS: There was a statistically significant difference in the shortest distance from the horizontal line at the surface of the cricoid cartilage to the lowest point of transverse process of C6 between neutral position and neck extension position in both males and females, and between males and females in both neutral position and neck extension position. The cricoid cartilage level was 4.8 mm lower in males and 14.4 mm higher in females than the lowest point of transverse process of C6 in neck extension position. CONCLUSIONS: Practitioners should recognize that the cricoid cartilage has cephalad movement in neck extension. In this way, the cricoid cartilage can be still useful as a landmark for stellate ganglion block.

PURPOSE: Obtaining a detailed family history through detailed pedigree is essential in recognizing hereditary colorectal cancer (CRC) syndromes. This study was performed to assess the current knowledge and practice patterns of surgery residents regarding familial risk of CRC. METHODS: A questionnaire survey was performed to evaluate the knowledge and the level of recognition for analyses of family histories and hereditary CRC syndromes in 62 residents of the Department of Surgery, Seoul National University Hospital. The questionnaire consisted of 22 questions regarding practice patterns for, knowledge of, and resident education about hereditary CRC syndromes. RESULTS: Two-thirds of the residents answered that family history should be investigated at the first interview, but only 37% of them actually obtained pedigree detailed family history at the very beginning in actual clinical practice. Three-quarters of the residents answered that the quality of family history they obtained was poor. Most of them could diagnose hereditary nonpolyposis colorectal cancer and recommend an appropriate colonoscopy surveillance schedule; however, only 19% knew that cancer surveillance guidelines differed according to the family history. Most of our residents lacked knowledge of cancer genetics, such as causative genes, and diagnostic methods, including microsatellite instability test, and indicated a desire and need for more education regarding hereditary cancer and genetic testing during residency. CONCLUSION: This study demonstrated that surgical residents' knowledge of hereditary cancer was not sufficient and that the quality of the family histories obtained in current practice has to be improved. More information regarding hereditary cancer should be considered in education programs for surgery residents.
