1.Clinical Study for Inhibition of Intimal Hyperplasia : Past & Present.
Journal of the Korean Society for Vascular Surgery 2008;24(2):155-162
INTRODUCTION: Intimal hyperplasia can be considered as a physiological reaction to the intravascular injury which occurs spontaneously in human body. But the fact that we can not block the intimal hyperplasia completely so far when there is any form of stimuli, can be thought to be as a result of not understanding thoroughly the pathological phenomenon about it. SUBJECT: There are many drugs, radiation therapies, stent, genetic treatment. Pharmacologic treatment with several drugs have been trided and most of them have all failed. Vascular brachytherapy resulted in no inhibition of restenosis. Stent is preferred to balloon angioplasty because of good patency. Genetic treatment is limited due to other E2F analogue. CONCLUSION: Although it is too early to predict the outcome of inhibition of intimal hyperplasia trials, these fundamental studies provide great evidences and hope that these clinical trials for inhibition of restenosis will eventually become effective option.

A ganglioneuroma is a rare benign tumor that originates in the neural crest, and is found along the path of the sympathetic chain, from the base of the skull to the pelvic cavity. It is characterized histologically by the composition of mature ganglion cells and nerve fibers. Due to the slow growth of the tumor, it may be incidentally found or detected by the pressure effects on adjacent structures. Herein, a case of a ganglioneuroma arising from the retroperitoneal sympathetic chain is reported in a 45-year-old female patient with a review of the literature.

Background:
Various implants are used to treat intertrochanteric fractures. However, the optimal implant to stabilize intertrochanteric femoral fractures is still a matter of debate. The purpose of the present study was to evaluate the midterm outcomes of patients treated using compression hip nails (CHNs).
Methods:
Between March 2013 and April 2018, 164 patients with intertrochanteric femoral fractures who were treated with internal fixation using CHNs were enrolled in this study. The mean age of the patients was 79.6 years. We retrospectively collected and estimated information such as reduction state, implant position, operation time, blood loss, hospital stay, time to achieve union, clinical scores (Harris hip score [HHS] and EuroQol five-dimensional [EQ-5D]), intraoperative complications (such as lag jamming and drill bit breakage), failure of fixation, avascular necrosis, and surgical site infection.
Results:
The mean follow-up period was 39.69 months. Eight percent of the patients required an open reduction. The mean operation time was 131 minutes, the mean blood loss was 221.19 mL, the mean hospital stay was 20.66 days, and the average time to union was 18 weeks. Intraoperative complications included 8 cases of breakage of the drill bit while making distal holes. The failure rate was 3.7% and revision surgery was performed in 6 cases (for cut-out in 5 and pull-out of the lag screw in 1). Asymptomatic venous thromboembolism occurred in 2 cases and hematoma requiring intervention occurred in 1 case. There were no other complications such as avascular necrosis, infection, and lateral irritation. At the 2-year follow-up, the averages of HHS and EQ-5D were 71.54 and 0.68, respectively.
Conclusions
Among the implants used to treat intertrochanteric femoral fractures, CHNs had a surgical failure of 3.7% and showed good radiologic and clinical results.

PURPOSE: This study directly compared clinical assessment scores and short-term systemic complications after total knee arthroplasty (TKA) between a group of patients aged 80 or older (141 patients) and another group of patients aged between 65 and 70 years (616 patients) with advanced osteoarthritis. MATERIALS AND METHODS: We retrospectively investigated 757 osteoarthritic patients who underwent primary TKA from January 2007 to January 2011 with a follow-up of 1 year. The surgery was performed using an extramedullary alignment guide instrument without invasion of the intramedullary canal to decrease embolic load and blood loss. RESULTS: At 1 year after surgery, the mean Knee Society knee score was improved in both groups (from 63.6 to 83.2 in octogenarians and from 68.3 to 89.0 in the younger group) and the level of satisfaction was excellent in both groups (8 in octogenarians and 8.3 in the younger group), even though there was no notable change in function score in the octogenarians (from 61.0 to 61.9 in the octogenarians and from 62.3 to 73.6 in the younger group). The total incidence of systemic complications (3.4% vs. 1.2%, p=0.400) and surgical complications (2.1% vs. 0.5%, p=0.229) showed no significant difference between groups. CONCLUSIONS: TKA yielded favorable clinical outcomes with a comparatively low postoperative complication rate in octogenarians despite the negligible functional improvement.

Henoch-Shonlein(H-S) purpura, or anaphylactoid purpura is a hypersensitivity vasculitis characterized by palpable purpura usually on buttock and low extremities; arthralgia mostly polyarhtralgia in the absence of frank arthritis; gastraintestinal involvement with colicky abdominal pain, nausea, vomiting, diarrhea, constipation and bleeding; and renal involvement, manifested chiefly by hematuria and proteinuria. Gastrointestinal involvement is seen in 70 percent of pediatric patients and one third of adult patients. Any portion of the gastrointestinal tract distal to the esophagus maybe involved, but most frequently affected sites are jejunum and ileum. We report one case of H-S purpura with duodenal involvement observed in 16, male patient.

Aorta-right atrial tunnel is a vascular anomaly that originates from the aortic sinus and terminates in either the superior vena cava or the right atrium. The patency of the tunnel can result in volume overload in both ventricles, bacterial endocarditis, aneurysm formation, and spontaneous rupture. Transesophageal echocardiography was performed in a 42-year-old male patient diagnosed with infectious endocarditis, and vegetation of the mitral and aortic valves, right atrial enlargement, and an extracardiac blood vessel connecting the aorta to the right atrium were discovered. Therefore, we were able to diagnose an aorta-right atrial tunnel leading to infectious endocarditis and proceeded with surgical treatment. Together with a review of the literature, we present a case report of a patient with aorta-right atrial tunnel accompanied by infectious endocarditis.

Jerusalem artichoke (JA) mainly consists of inulin. In many experimental studies, inulin has been shown to be beneficial for decreasing glucose level. Therefore, JA is lately attracting wide attention as an anti-diabetic food. Therefore, many patients ingest JA in extract form. However, there are no published clinical studies in patients with diabetes to demonstrate benefit from the use of inulin-type fructans. We experienced a diabetes inpatient with acute hyperglycemia associated with JA. We could not control the patient's blood glucose in spite of addition and increment of insulin. We found that she had taken extracts of JA and recommended cessation. After discontinuing JA extracts, her blood glucose was well controlled in spite of discontinuation of insulin. Thus, in this patient, JA had actually increased blood glucose. We suggest that JA may be dangerous for use in diabetic patients.

PURPOSE: In our previous study, we have shown the main cell death pattern induced by irradiation or protein tyrosine kinase (PTK) inhibitors in K562 human myelogenous leukemic cell line. Death of the cells treated with irradiation alone was characterized by mitotic catastrophe and typical radiation-induced apoptosis was accelerated by herbimycin A (HMA). Both types of cell death were inhibited by genistein. In this study, we investigated the effects of HMA and genistein on cell cycle regulation and its correlation with the alterations of radiation-induced cell death. MATERIALS AND METHODS: K562 cells in exponential growth phase were used for this study. The cells were irradiated with 10 Gy using 6 MeV Linac (200-300 cGy/min). Immediately after irradiation, cells were treated with 250 nM of HMA or 25 microM of genistein. The distributions of cell cycle, the expressions of cell cycle-related protein, the activities of cyclin-dependent kinase, and the yield of senescence and differentiation were analyzed. RESULTS: X-irradiated cells were arrested in the G2 phase of the cell cycle but unlike the p53-positive cells, they were not able to sustain the cell cycle arrest. An accumulation of cells in G2 phase of first cell-cycle post-treatment and an increase of cyclin B1 were correlated with spontaneous, premature, chromosome condensation and mitotic catastrophe. HMA induced rapid G2 checkpoint abrogation and concomitant p53-independent G1 accumulation. HMA-induced cell cycle modifications correlated with the increase of cdc2 kinase activity, the decrease of the expressions of cyclins E and A and of CDK2 kinase activity, and the enhancement of radiation-induced apoptosis. Genistein maintained cells that were arrested in the G2-phase, decreased the expressions of cyclin B1 and cdc25C and cdc2 kinase activity, increased the expression of p16, and sustained senescence and megakaryocytic differentiation. CONCLUSION: The effects of HMA and genistein on the radiation-induced cell death of K562 cells were closely related to the cell cycle regulatory activities. In this study, we present a unique and reproducible model in which for investigating the mechanisms of various, radiation-induced, cancer cell death patterns. Further evaluation by using this model will provide a potent target for a new strategy of radiotherapy.

BACKGROUND: Elderly patients usually have comorbid and poor general conditions. They are more likely to have complex coronary lesions with cardiac dysfunction. Percutaneous coronary intervention (PCI) in octogenarians remains controversial. In this study, we determined the safety after PCI for octogenarians and their younger counterparts with coronary artery disease. METHODS: We reviewed 1,057 patients (110 octogenarians vs. 947 younger counterparts) who underwent PCI for coronary artery disease at Saint Carollo Hospital. We analyzed the baseline characteristics, angiographic findings, in hospital mortality, and post procedural complications between the two groups. RESULTS: The mean ages of octogenarians and younger counterparts were 83.1+/-4.5 years and 62.6+/-10.3 years, respectively. The octogenarian group had a significantly (p<0.001) higher ratio of female patients compared to their younger counterpart group (57.3% vs. 27.5%). However, the octogenarian group had a significantly (p=0.035) lower ratio of patients with history of diabetes mellitus compare to their younger counterpart group (22.7% vs. 32.6%). Incidence of acute myocardial infarction in octogenarians was significantly (p<0.001) higher than that in the younger counterparts (43.7% vs. 18.0%). There was no significant difference in admission duration, major complication, or in-hospital mortality between two groups. CONCLUSION: Our results revealed that hospital mortality and incidence of major complications in octogenarians who underwent invasive PCI were not higher than those in their younger counterparts, suggesting that PCI could be safely used in patients aged 80 years or older. However, long-term follow-up data are needed.
