Fractures of the phalanges of the hand are very common. Many are minor and likely to have a good result. However many other phalangeal fractures cause significant and prolonged disability. Non-union of the tubular bones of the hand are uncommon occurrence, but are often associated with functional deficits. The authors have reviewed 7 cases of non-union of the phalanges which were treated in the department of orthopaedic surgery, National Medical Center from 1978 to 1985. The results were summarized as follows: 1. The non-union of phalangeal bone was defined by clinical symptoms and signs and roentgenological examination. 2. The incidence of non-union of phalangeal bone fractures was 0.9% (7/771 cases.) 3. of 7 patients, there were 6 in male and 1 in female. 4. Non-union occurred more commonly in the second decade and the group between 10 and 30 years of age. 5. Seven cases, all were the right handed, but injury was developed in the left hands except two cases. 6. The causes of non-union were thought as open wound (7 cases), type of fracture (simple or comminution:3 cases), inadequate immobilization (4 cases) and overtraction (1 case). 7. of 7 cases, 4 cases were treated with bone peg graft and K-wire fixation and 2 cases with excision of distal fragment. 8. The clinical union was 9 weeks in average.

In spite of recent development in fixation technique we still have lots of complication including avascular necrosis of femoral head. For many years, orthopaedic surgeon have been searching for a simple, safe, accurate and reliable clinical test to asses the vascular status of the femoral head. In early detection of viability of the femoral head, nothing is more certain than bone scan at the moment. Bone scan can detect or predict the viability of the femoral head. Subramanian and McAfee introduced 99mTc-Sn-polyphosphate as a bone seeking agents. We applied serial bone scan in 19 cases of femur neck fractures from 1982 to 1985 at the department of orthopaedic surgery, National Medical Center. The results were as follows; 1. The uptake ratio of displaced and undisplaced group based on preoperative radiography was 1.ZO, 1.46, 1.52, 1.55, and 0.63, 1.23, 1.81, 1.58 in average in postoperative bone scan interval 1–2 wks, 3 months, 6 months, 12 months. The bone scan uptake ratio was lower in the former than the latter, but after 3 months, there was no remarkable difference between them. 2. At the time of 1 to 2 weeks, 3 months, 6 months and 12 months, uneventful group was 0.74, 1.27, 1.72, 1.62 and avascular necrosis group 0.13, 0.18, 0.30, 0.67 in the uptake ratio. In 2 cases of avascular necrosis, the uptake ratio was markedly decreased. 3. There was no difference between the group operated within 48 hour after injury and the group delayed later.

Pheochromocytoma is a hazardous and dramatic cause of hypertension. This potentially lethal neoplasm originates in most cases in the adrenal medulla and less frequently in the cells of the extraadrenal paraganglion system which are disseminated along the paravertebral axis from the pelvis to the base of the skull. The organ of Zuckerkandl is paraganglia lying the abdominal aorta with highest incidence in the region of the inferior mesenteric artery and usually degenerate shortly after birth. In the literature, and additional one case of pheochromocytoma arising from the organ of Zuckerkandl associated with intracerebral hemorrhage which was treated recently in the Kyung Hee University Hospital is presented in this report.

OBJECTIVE: To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. MATERIALS AND METHODS: Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. RESULTS: The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL +/- 6.8 before stent insertion, decreased to 4.58 mg/dL +/- 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 +/- 99 days, and the median patient survival was 179 +/- 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). CONCLUSION: Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

PURPOSE: We investigated the impact on prostate-specific antigen (PSA) and prostate volume (PV) of statin medication for 1 year in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We retrospectively investigated 791 patients in whom BPH was diagnosed. For analysis, the patients were divided into four groups according to their medications: group A, alpha-blocker; group B, alpha-blocker+statin; group C, alpha-blocker+dutasteride; group D, alpha-blockers+statin+dutasteride. To investigate changes in serum PSA, PV, and total cholesterol, we analyzed the data at the time of initial treatment and after 1 year of medication. RESULTS: After 1 year, group A showed a 1.3% increase in PSA and a 1.0% increase in PV. Group B showed a 4.3% decrease in PSA and a 1.8% decrease in PV. The difference in PV reduction between groups A and B was statistically significant (p<0.001). Group C showed a 49.1% reduction in PSA and a 22.9% reduction in PV. Group D showed a 51.6% reduction in PSA and a 24.5% reduction in PV. The difference in PV reduction between groups C and D was not statistically significant (p=0.762). By use of a multivariate logistic regression model, we found that the probability of PV reduction after 1 year was more than 14.8 times in statin users than in statin nonusers (95% confidence interval, 5.8% to 37.6%; p<0.001). CONCLUSIONS: Statin administration reduced PSA and PV in BPH patients. This finding may imply the improvement of lower urinary tract symptoms and prevention of cardiovascular disease and chemoprevention of prostate cancer with statin treatment.

Familial adenomatous polyposis (FAP) includes early development of up to thousands of colorectal adenoma and of colonic adenocarcinoma in all untreated cases. Moreover, a variety of extracolonic manifestation are seen. Several reports have demontrated a high incidence of papillry carcinoma of thyroid. We experienced a case of familial adenomatous polyposis, presenting with thyoid papillry carcinoma, and reported with a brief review of literatures.

Keratinocytes are constantly exposed to extracellular insults, such as ultraviolet B, toxic chemicals and mechanical stress, all of which can facilitate the aging of keratinocytes via the generation of intracellular reactive oxygen species (ROS). Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that plays a critical role in protecting keratinocytes against oxidants and xenobiotics by binding to the antioxidant response element (ARE), a cis-acting element existing in the promoter of most phase II cytoprotective genes. In the present study, we have attempted to find novel ethanol extract(s) of indigenous plants of Jeju island, Korea that can activate the Nrf2/ARE-dependent gene expression in human keratinocyte HaCaT cells. As a result, we identified that ethanol extract of Cirsium japonicum var. ussuriense Kitamura (ECJUK) elicited strong stimulatory effect on the ARE-dependent gene expression. Supporting this observation, we found that ECJUK induced the expression of Nrf2, hemoxygenase-1, and NAD(P)H:quinone oxidoreductase-1 and this event was correlated with Akt1 phosphorylation. We also found that ECJUK increased the intracellular reduced glutathione level and suppressed 12-O-tetradecanoylphorbol acetate-induced 8-hydroxyguanosine formation without affecting the overall viability. Collectively, our results provide evidence that ECJUK can protect against oxidative stress-mediated damages through the activation of Nrf2/ARE-dependent phase II cytoprotective gene expression.

PURPOSE: We investigated the significance of bcl-2 and p53 protein expressions as the prognostic factor in metastatic prostate adenocarcinoma. MATERIALS AND METHODS: Nineteen paraffin-embedded prostatic cancer tissues were examined using immunohistochemical staining for bcl-2 and p53 protein. We evaluated correlation of bcl-2 and p53 protein expressions with cancer progression free interval, pretreatment PSA and Gleason score. RESULTS: Seven out of 19 cases (36.9%) were positive for p53 and 3 cases (15.8%) were positive for bcl-2 protein. Mean disease progression free interval in positive patients for bcl-2 and p53 protein expressions was 8.7 months and 10.3 months, respectively. However, it was 18.3 months and 21 months in negative expressions, respectively. The difference of mean disease progression free interval between positive and negative groups for p53 protein expression was statistically significant (p<0.05) but not in bcl-2 protein groups. The rates of positive staining for bcl-2 and p53 protein were 0% (0/8) and 37.5% (3/8), respectively, in Geason score 5-7 groups, 27.3% (3/11) and 36.4% (4/11) in 8-10 groups. Neither of proteins had significant correlation with Gleason score and pretreatment PSA. CONCLUSIONS: The expression of p53 protein was correlated with significant short disease progression free interval but bcl-2 overexpression had relative short disease progression interval without statistical significance. These results suggest that expressions of bcl-2 and p53 have considerable prognostic impact and these gene products would provide useful information about prognosis of metastatic prostate adenocarcinoma.
