BACKGROUND: Despite general agreement as to the safety and immediate success of percutaneous iliac angioplasty, its long-term efficacy remains subjects to debate and percutaneous transluminal angioplasty(PTA) induced dissection in the iliac artery may also lead to urgent surgery although frequency of this complication is not clearly stated in the literature. The relatively early result with the use of the Palmaz balloon-expandable intraluminal stent(BEIS) for treating atherosclerotic iliac artery and PTA-induced iliac artery dissections strongly suggest that Palmaz BEIS has its important role for limitations of PTA.It is generally accepted that indications for stent placement are (a) inadequate immediate postangioplasty response (b) restenosis after previous iliac balloon angioplasty, and (c) total iliac artery occlusion. METHODS: We report the successful implantation of Palmaz BEIS at right common iliac artery in a patients suffered from severe claudication. Previously the patients received PTA two times. First PTA resulted in intimal dissection and restenosis occurred after successful second PTA. RESULTS: After successful implantation of Palmaz BEIS, pressure gradients across the lesion and blood flow pattern were nearly normalized. The patients was discharged without symptom and was in good condition after 4 months follow-up. CONCLUSION: According to our this limited experience and other reports, stent placement in valuable adjunct in the management of iliac artery disease.

Desmoplastic trichoepithelioma, a tumor of hair follicle, is usually seen as solitary lesions. Its clinical configuration is hard and annular, asympromatic, white or yellowish and varied in size from 3 to 8 mm, but the appearance of these lesion is not so distinctive to hair follicle tumors that the diagnosis is estabilished by the histopathologic findings. Microscopical findings of desmoplastic trichoepithelioma consist of narrow strands of tumor cells, horn cyst, desmoplastic stroma. We present here a case of desmoplastic trichoepitheliorna, which develops as 6 mm sised papule on the left cheek in a 57-year-old woman.

PURPOSE: The aim of this study is to develop and evaluate an infection prevention self-care application for cancer patients who have been discharged from hospital after receiving chemotherapy. METHODS: The app was developed through five stages: analysis, design, development, implementation and evaluation. The app's contents included infection prevention education, checking daily self-management, checking daily inquiry and information about the app. Cancer patients undergoing chemotherapy were asked to use the app and then a nonequivalent control group non-synchronized design was conducted to analyze the effect of the app on infection prevention self-care knowledge, self-care performance, infection occurrence and temperature. Twenty-two patients in the experimental group and twenty-four patients in the control group participated in this study. RESULTS: The self-care knowledge score (t=6.74, p<.001) and self-care performance score (t=13.44, p<.001) were statistically higher in the experimental group compared with the control group respectively. The infection occurrence was not different between the experimental and control groups. But temperature in the control group was statistically higher than in the experimental group (t=-2.39, p=.021). CONCLUSION: The infection prevention self-care application for cancer patients receiving chemotherapy was an effective intervention to decrease infections during home care.

Palliative open nephrostomy was done on 50 cases with advanced pelvic malignancy and benign conditions in the Department of Urology, Seoul National University Hospital during the period of March, 1979 to July, 1982. The results were as follows: 1. 20.5% (9/44) of our patients died without being discharged from the hospital after nephrostomy. 2. In advanced pelvic malignancy, only 52.6% of patients alive at 3 months and only 26.3% alive 6 months. 3. In advanced pelvic malignancy, the post-nephrostomy complication was 46.7% and the most common complication was various urinary problems. 4. The cause of death was multifactorical and impossible to define precisely. The nephrostomy complications were at least in part contributory to the deaths. 5. The terminal malignancy patients who might not expected to live six months and to lead a useful, relatively comfortable life outside the hospital after treatment could not have benefited from nephrostomy. Unavoidable cases, we recommended percutaneous nephrostomy and passage of ureteral catheters instead of open nephrostomy.

Objective : The aim of this study was to evaluate cross - reactivity between pollens in patients with strong skin reactivity to multiple pollens. METHODS: A pool of sera from 20 patients who showed strong skin responses( > or = 3+ ) to all three kinds of pollens ( tree, grass, and weed ) was used. Oak, ryegrass, mugwort, ragweed and hop Japanese pollens were chosen for the subject of study. The level and pattern of bound IgE to each pollen and cross - reactivity between pollens were investigated by ELISA and immunoblot experiments. RESULTS: In ELISA, the IgE of a pool of sera reacted to ryegrass and ragweed in 100%, to mugwort in 95%, to oak in 75%, and to hop Japanese in 65%, respectively. In inhibitory ELI - SA, more than 50% of bound IgE was mutually inhibited in oak vs ryegrass, oak vs mugwort, mugwort vs ryegrass and mugwort vs hop Japanese. In immunoblot, the IgE binding rate to major allergens of each pollen was 95% for hop Japanese, 75% for ragweed, 50% for ryegrass, 35% for mugwort, and 30% for oak, respectively. In inhibitory immunoblot, the mutually inhibited bound IgE could not be observed between major allergens of each pollen, but some minor allergens of oak pollen were mutually inhibited by ryegrass. CONCLUSION: Cross - reactivity between major allergens of oak, ryegrass, mugwort, ragweed and hop Japanese pollens was not observed at all, but some minor allergens of oak pollen cross-reacted with ryegrass and mugwort, and so did those of mugwort pollen with ryegrass and hop Japanese.

BACKGROUND: IL - 5 has been recognized as a potent proeosinophilic cytokine and IL-10 has been reported as an important anti - inflammatory cytokine in allergic inflammation. But the clinical roles of these cytokines in allergic asthma are still unclear. Objectives : We studied the clinical implications of IL - 5 and IL - 10 secretions from stimulated peripheral blood mononuclear cells ( PBMC ) in Dermatophagoides farinae ( DF ) atopic asthmatics ( BA ). METHODS: Thirty - six DF sensitized BA and 9 non - atopic BA were enrolled for this study. Twenty - seven out of 36 subjects were challenged by inhalation of DF crude allergen. The isolated PBMCs were cultured for 6 days with DF antigen and the stimulatory index ( SI ) and secretions of IL - 5, IFN - y and IL - 10 from PBMC were measured. We analyzed these parameters with clinical parameters. RESULTS: SI (4.2 +/- 1.0 vs. 1.3 +/- 0.3, p<0.05) and secretions of IL - 5 ( 19.9 vs. 1.7 g/L, p< 0.001 ) and IL-10 ( 185.5 vs. 34.3 g/L, p(0.05 ) from the atopic BA were significantly higher than those of non-atopic BA, but the secretion of IFN - r was not different between the two groups ( 56.6 vs. 47.3 ug/L ). No significant difference in secretions of IL - 5, IL - 10, IFN - r and SI of PBMC was found between responder and non - responder of DF inhalation challenge test. Among responders to antigen challenge test ( n = 17 ), the production of IL - 5 correlated with the productions of IL - 10 (r = 0.773, p< 0.01 ) and methacholine PC20 ( r = 0.503, p< 0.05 ). Production of IL - 5 from the PBMC of atopic mild intermittent BA ( n = 10 ) was higher than that of atopic per'sistent BA ( n = 27 ) ( p< 0.01 ), but no difference in IL - 10, IFN - r and SI was found between the two groups. Conclusions : Allergen specific productions of IL - 5 and IL - 10 from the PBMC may be specific for atopic subjects and secretion of IL - 5 from the stimulated PBMC may contribute to the pathogenesis of atopic BA. The severity of BA may be more influenced by other factors.

BACKGROUND: Total obstruction of the left main coronary artery is a common cause of sudden death but is rarely seen in patients who survive to undergo diagnostic evaluation or treatment. METHODS: During twenty six-year period, we encountered 5 patients with chronic total obstruction of the left main coronary artery out of about 4,000 patients who underwent coronary angiography. RESULTS: All patients have undergone coronary bypass surgery. These patients present with increasingly severe angina. A right dominat coronary anatomy is always found, usually with well-developed right-to-left collaterals. Left ventricular function was severely impaired in two patients out of five patients. CONCLUSIONS: The results of surgical revascularization in our patients and others described in the literature can support the safety and efficacy of this approach.

A 61-year-old woman, who had been treated by acupuncture on the glabellar region due to frontal headache ten days ago, had a rapidly growing tumor on that region. Histopathologically, the tumor was shown to be a central crater filled with eosinophilic keratin & a marginal but-tress formed by invagination of the epidermis. According to clinical & histopatholpgical findings, we can easily diagnose our case as solitary keratoacanthoma. As shown in our case, we think that acupuncture should be counted as one of the causative factors in the development of solitary keratoacanthoma.
