PURPOSE: To evaluate clinical results of posterior cruciate retaining TKA according to the preoperative range of motion (ROM), degree of deformity and obesity. MATERIALS AND METHODS: 81 cases were followed up more than 3 years. All cases were evaluated according to degree of preoperative ROM and varus deformity, presence of flexion contracture and BMI scale for obesity. Clinical and radiological evaluation systems were used with American knee society scale. RESULTS: Postoperative ROM according to the degree of preoperative ROM showed that the postoperative ROM in the good preoperative ROM group was better compared to the worse preoperative ROM groups and the results of knee scores showed the similar condition. Flex-ion contracture group revealed the better clinical results (p>0.05) compared to the group without contracture. The improvement of knee and functional scores was statistically significant in the more deformed varus groups and in the normal BMI group compared to the more obese groups. CONCLUSION: Good clinical results and satisfactory postoperative ROM are obtained by the good preoperative ROM, appropriate technique of maintaining adequate soft tissue balance in the deformed knee and preoperative weight control.

Mucinous adenocarcinoma of the prostate is very rare tumor and comprises about 0.4% of all prostatic carcinomas. The metastatic form of mucinous adenocarcinoma of the prostate is similar to that of the adenocarcinoma of the prostate. Common sites of metastasis are pelvic lymph node and bone. At presentation, half of patients have evidence of metastasis to pelvic lymph nodes, bone, brain, liver, bladder and seminal vesicles. Especially, epididymal metastasis from mucinous adenocarcinoma of the prostate is uncommon and only 15 cases was reported in the literature. We report a case of mucinous adenocarcinoma of the prostate with metastasis to the epididymis and discuss the clinicopathologic features of this lesion.

OBJECTIVES: To identify prevalence of dementia and it's subtypes in patients with Hansen's disease in a sanatorium of Korea. METHODS: The study employs a two-stage design for case identification. One hundred-six patients with Hansen's disease aged 65 and over participated in the study. The Korean Version of the Consortium to Establish a Registry for Alzheimer's disease (CERAD-K) assessment packet was administered to One hundred-two patients with Hansen's disease. Dementia was defined using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnostic features of dementia. RESULTS: The prevalence was 15.1% in Hansen's sanatorium. The prevalence of Alzheimer's and vascular dementia were 10.4% and 4.7%. The age-adjusted prevalence rate for dementia was 11.9%. The rate of patients with dementia was 12.73% in males and 17.65% in females. CONCLSION: The prevalence of dementia in Hansen's disease sanatorium of Korea appears to be similar with those reported in previous study. Our result suggests that Hansen's disease was unrelated to prevalence of dementia, and also that the dementia is major neuropsychiatric disease in patient with Hansen's disease.

Median sternotomy incision is world-widely used for open heart surgery, especially in valvular heart disease. But recently, minimally invasive approach by the right parasternal incision for valvular heart disease was introduced with the many merits by small incision. We experienced 1 case of mitral valve repalcement by right parasternal incision and extended transseptal approach. This technique has no specific complications or problems compared with the median sternotomy and was proven by the excellent exposure. Cosmetically, the patient was satisfied with the incision.

Concomitant fracture of the lateral process of the talus and the sustentaculum tali of the calcaneus is a rare injury. There are few references in the literature that comment on the precise injury mechanism and the operative method for this type of fracture. We achieved satisfactory clinical results in 2 cases of concomitant fractures of the lateral process and the sustentaculum tali resulting from traffic accidents. We used a method of open reduction and internal fixation. We report these cases with a review of the relevant foreign literature because of no previous report in Korean literature.

BACKGROUND/AIMS: There are several staging systems to decide the stage of hepatocellular carcinoma (HCC), but yet incomplete. Okuda stage which includes both tumor characteristics and liver function is widely used. The aims of this study were to assess the usefulness of known prognostic factors and Okuda staging system in 237 cases of HCC. METHODS: A retrospective analysis of 237 cases of HCC diagnosed from 2000 to 2002 was performed. We analyzed prognostic factors such as age, sex, liver cirrhosis, Child-Pugh classification, tumor size, albumin, bilirubin, alpha-FP, ascites, encephalopathy and Okuda stage. Prognostic analysis was performed for single variables and estimating survival distributions were analyzed by the Kaplan-Meier method, statistically compared by the log-rank test. RESULTS: Patients had a mean age of 57.5 years and were predominantly men (79.7%). Liver cirrhosis were noticed in 214 cases (90.3%). The overall median survival period was 25.7 months. The median survival period was correlated to bilirubin, ascites, alpha-FP, tumor size, and Child-Pugh classification, but not to age, sex, and pattern of viral infection. The median survival period of the Okuda stage I, II and III cases was 35.8, 11.9 and 8.5 months (p<0.001). CONCLUSIONS: The median survival period of patients with HCC is significantly correlated to Okuda staging system, and survival period has improved than the initial data when the Okuda staging system was published in 1985. However, in order to discriminate early staged HCC more accurately, other prognostic factors such as alpha-FP and tumor morphology should be included in future staging system for HCC.

BACKGROUND: This study was performed to evaluate the effects of pre-emptive subdiaphragmatic instillation of lidocaine before pneumoperitoneum on postoperative pain following a laparoscopic cholecystectomy (LC) and also to evaluate it's effect on the changes of blood pressure during an operation. METHODS: Thirty-three relatively healthy patients for an LC were allocated into the two groups. after the induction of general anesthesia with sodium thiopental, vecuronium, nitrous oxide and enflurane (1-2 vol%), 0.2% lidocaine 200 ml was subdiaphragmatically instilled 10 min before pneumoperitoneum in the lidocaine group (n = 15), and normal saline in the control group (n = 18). The changes of the systolic and mean arterial pressure (SAP and MAP), postoperative pain score, and the number of analgesics used during the postoperative 24 h were compared between two groups. RESULTS: The pain scores at postoperative 1, 3, 6, 12, 18 and 24 h and the number of analgesics used were significantly low in the lidocaine group compared to the control group (P<0.01). The elevations of SAP and MAP during pneumoperitoneum were significantly attenuated in the lidocaine group (P<0.01). CONCLUSIONS: This data suggests that subdiaphragmatic instillation of lidocaine before pneumoperitoneum is effective in the control of postoperative pain following an LC and also effective to attenuate the elevation of blood pressure during pneumoperitoneum. However, further study is needed to evaluate the safety of these methods before recommendation of routine use.

PURPOSE: The purpose of this study is to evaluate the rate and direction of subsidence that occurred after anterior cervical discectomy and fusion using the polyetheretherketone (PEEK) cage and to analyze the risk factors of subsidence. MATERIALS AND METHODS: Thirty two patients (36 segments) who underwent anterior cervical discectomy and fusion using the PEEK cage and autologous cancellous iliac bone graft from July 2003 to November 2011 were enrolled in this study. anterior segmental height (ASH), posterior segmental height (PSH) and cage corner distance (CCD) were measured on plain radiographs. Subsidence was defined as > or =2 mm decrease in the average of ASH and PSH at the final follow up compared to that measured in the immediate postoperative period. A decrease of more than 3 mm was defined as severe subsidence for further statistical analysis. RESULTS: Subsidence of more than 2 mm was observed in 14 segments (38.9%) and severe subsidence (> or =3 mm) was observed in seven segments (19.4%). The direction of subsidence was examined by comparison of means of decreased ASH and PSH and anterior subsidence outweighed posterior subsidence (p<0.001). Examination of CCD showed that inferior subsidence was more frequent than superior subsidence (p<0.001, p=0.047). Among the suspicious risk factors for subsidence, intraoperative disc space distraction (anterior distraction: p=0.031, posterior distraction: p=0.007) and height of inserted cage (p=0.032) showed statistical significance. CONCLUSION: Considerable incidence of subsidence was observed after use of the cage. Using a cage of appropriate height and prevention of intraoperative over-distraction of disc space will be helpful to prevention of subsidence of the cage after anterior cervical discectomy and fusion using the PEEK cage.
