BACKGROUND: The propose of this study was to identify the level of medical technologists' perception of and compliance with hospital infection control guidelines. METHODS: A questionnaire survey was conducted for 65 medical technologists working at three university hospitals in Seoul and Kyunggi areas. The questionnaire was composed of 34 questions on the general characteristics (14 items) of individual responders and about infection control guidelines (20 items). Their response was marked on the basis of 5 points for each question. RESULTS: The mean scores of the perception of and compliance with the infection control guidelines were 4.62+/-0.34 and 3.85+/-0.42, respectively. The female technologists scored significantly higher than did the male counterparts in the participation level of the infection control guidelines (P<0.05). The medical technologists who had participated in an infection control educational program were more likely than those who had not to show a higher compliance level on the infection control guidelines (P<0.05). CONCLUSION: The study demonstrated that the development of infection control educational programs for medical technologists and a supportive policy of the hospital administration should contribute to the prevention of nosocomial infections.

Desmoid tumors are defined as aggressive overgrowth of fibrous sheets and musculoaponeurotic structures. Although desmoid tumors are generally known as a benign neoplasm, it's aggresive local invasiveness and frequent recurrence indicate it's position lying between the benign and malignancy. The association of desmoid tumor and familial adenomtous polyposis(FAP) was first made in 1923 by Nichols. In 1951, Gardner reported the familial occurrence of intestinal polyposis, osteomas, fibromas, and epidermal or sebaceous cyst. Desmoid tumors are common in patients with FAP and Occur in 3.5~29% of patients with FAP whereas the incidence in the gerenal population is 2~5/1,000,000 person years. Surgical resection of desmoids in patients with FAP has been controversial because unresectability and recurrence are more common than cure. Palliative and curative resections have a high morbidity. Surgery should be reserved for those patients with symptomatic mesenteric desmoids. If a small mesenteric desmoid is encountered incidentally and is easily resectable, it should be resected. If surgery has been less than satisfactory in the treatment of these patients, several different medical approaches can be combined with or without surgical resection with mixed result. Authors report a case of unresectable mesenteric desmoid tumor, developing after surgery of FAP and literatures were reviewed

Exercise-induced anaphylaxis can be associated with ingestion of a specific food. We experienced a case of exercise-induced anaphylaxis followed by ingestion of parsely. A 22- year old female patient was presented with angioedema of the face and chest tightness induced by running after ingestion of parsley within 15 minutes. She had suffered from allergic rhinitis. She had positive reactions to mugwort pollen and parsely extract on skin prick test in a dose dependent manner. Although the oral provocation test with parsely could not induce bronchoconstriction, we could diagnosed as parsely dependent exercise induced anaphylaxis based upon skin prick test and history.

STUDY DESIGN: Retrospective controlled study. OBJECTIVES: The aim of this study was to determine if unilateral TLIF is comparable to conventional PLIF with regard to radiologic and clinical outcomes, and to examine the viability of local bone for bone grafting in lumbar interbody fusion. SUMMARY OF LITERATURE REVIEW: TLIF, a modified form of PLIF, is a new spinal fusion technique that avoids the typical complications of PLIF. MATERIALS AND METHODS: We analyzed 32 cases of single-level TLIF or PLIF in patients with degenerative or isthmic spondylolisthesis, who were followed for more than 1 year. The patients in group 1 underwent TLIF, and the patients in group 2 underwent PLIF. The fusion rate, changes in disc height, and degree of anterolisthesis in the fused segment were analyzed radiologically. The clinical results were evaluated using the Oswestry Disability Index and visual analog scale. We also analyzed operative time, blood loss, and complications in both groups. RESULTS: Radiologically and clinically, there were no significant differences between the two groups in terms of fusion rate, changes in disc height, or degree of anterolisthesis in the fused segment. The mean operative time was 200 minutes in group 1 and 240 minutes in group 2. The mean blood loss was 854 ml in group 1 and 1102 ml in group 2(p>0.05). CONCLUSIONS: TLIF is a potentially useful alternative to conventional PLIF in patients with degenerative or isthmic spondylolisthesis. Additionally, local bone may be a viable source of bone grafts for single-level TLIF and PLIF.

BACKGROUND: Interleukin-5 (IL-5), IL-3, and GM-CSF are known to prolong the survival of eosinophils, and IL-5 has the most potent effect on eosinophil survivaL It is also known that divergent signals induce apoptosis in different cells. But, There have been few reports on about the intracellular signals that trigger the effectors of apoptosis. Cyclic AMP (cAMP) can modulate apoptosis in many cells. But, the role of intracellular cAMP in the IL-5 induced eosinophil survival is still not completely understood. OBJECTIVES: This study was aimed to elucidate the role of intracellular cAMP in IL-5 induced eosinophil survival. MATERIAL AND METHOD: Eosinophils were isolated from peripheral blood of atopic patients. Eosinophil viability was measured by means of propidium iodine (PI) method and the number of viable cells was counted by FAC scan (Becton Dickinson, USA). Cells were cultured with or without IL-5, and also with various cAMP-elevating agents (dibutyryl cAMP, 8-bromo-cAMP, N6- benzoyl cAMP). The concentrations of cAMP were measured by cAMP enzyme immunoassay system(BiotrakTM, Amersham). Finally cAMP dependent protein kinase A inhibitor (H8) was added to eosinophils to examine the effect of decreased intracellular cAMP activity on the viability of eosinophils stimulated with IL-5. RESULTS: The percentage of viable eosinophils was reduced rapidly from 92.1+/-1.8% to 8.23+/- 3.41% without IL-5 (p<0.05; n=ll, 4-day incubation). Upon addition of IL-5, it was increased to 33.02+7.8% (p<0.05; n=ll). In the absence of IL-5, the addition of cAMP-elevating agent increased eosinophil viability in a dose-dependent manner. Upon addition of H8 (24 uM), the eosinophil viability increased by IL-5 (52.5+/-6.4%) was significantly reduced to 27.2+/-5.4% (p<0.05;n=7). Compared with tissue culture media (TCM) only, IL-5 produced persistent elevation of intracellular cAMP of eosinophils in a time and dose dependent manner.

PURPOSE: To investigate factors influencing the amount of indirect reduction by ligamentotaxis according to timing of surgery, extent of surgery, and characteristics of fractures. MATERIALS AND METHODS: We reviewed 22 cases of thoracolumbar fracture which had been performed posterior instrumentation and fusion using pedicle screw system. We divided patients into each group according to timing of surgery, number of fusion segment, insertion of screw on fractured vertebra, and rupture of posterior ligament complex, and Denis type. We measured changes of kyphotic angle, anterior vertebral height and wedge angle on plain radiographs, and we compared spinal canal area before and after operation using computed tomographic scans. RESULTS: Kyphotic angle, anterior vertebral height, wedge angle, and area of spinal canal showed significant improvement postoperatively. The wedge angle improved significantly operated within 3 days after injury, however, kyphotic angle and anterior vertebral height had no correlation with variable factors except the rupture of posterior ligament complex. The amount of restoration of spinal canal also affected only by rupture of posterior ligament complex. CONCLUSION: There is little relationship between timing of surgery and canal restoration, so we cannot conclude that prompt operation helps reduction of narrowed spinal canal. Otherwise narrowed spinal canal had much less restored by ligamentotaxis when there were rupture of posterior ligament complexes.

Robinsoniella peoriensis has recently been identified as a Gram-positive, spore-forming, anaerobic rod originally recovered from swine manure storage pits. To date, 6 cases of R. peoriensis infection have been reported, including 2 cases of bacteremia, 1 of abdominal fluid collection, and 3 of wound infection. In the present study, we report a 76-yr-old man with R. peoriensis bacteremia who developed aspiration pneumonia. Gram staining of a purified colony revealed Gram-positive, rod-shaped bacteria. Biochemical identification using API 20 A (bioMerieux, France) indicated presence of Clostridium spp. We performed both 500-bp and full-gene sequencing of 16S rRNA of the isolate. The sequence was analyzed with MicroSeq ID 16S rRNA Library v2.0 (Applied Biosystems, USA), GenBank Basic Local Alignment Search Tool (BLAST) (http://www.ncbi.nlm.nih.gov/genbank), and EzTaxon database v2.1 (http://www.eztaxon.org). The 500-bp 16S rRNA sequence of the blood culture isolate showed 99.16-99.79% similarity with R. peoriensis and the full-gene 16S rRNA sequence showed 98.87-99.50% similarity with R. peoriensis. The organism was confirmed as R. peoriensis by using all of the mentioned databases except for MicroSeq, which did not include the RNA sequence of this bacterium. This case suggests that identification of R. peoriensis might be challenging in clinical laboratories with no access to molecular methods, as certain commercial identification systems may not identify, or may misidentify, this organism. To the best of our knowledge, this is the first report of the isolation of R. peoriensis in Korea.

OBJECTIVE: Throughout the past several years, there have been a number of entertainment celebrity suicides in South Korea. The aim of this study was to investigate the clustering of suicides following celebrities' suicides in South Korea from 2005 to 2008, particularly according to certain characteristics. METHODS: Seven celebrity suicides were examined and defined using the Korean Integrated Newspaper Database System (KINDS) and from these, we considered four affected periods occurring 28 days after each celebrity's suicide. A Poisson time-series autoregression model was used to estimate the relative risk of the total suicide number for each affected period from 2005 to 2008. Logistic regression analysis was performed to investigate whether there were specific increases in the numbers of suicides in subgroups matching each celebrity. RESULTS: There were significant increases in the risk of suicide during the affected periods. Remarkable increases were found in the subgroups matching each celebrity, especially in the group in which all factors (sex, age, and method) were similar. CONCLUSION: This study provides confirmation that a significant copycat effect was induced by these celebrities' suicides, especially among people who identified more with the celebrities. This implies that countermeasures for upright media coverage of celebrity suicides should be discussed and practiced properly in South Korea.

PURPOSE: To evaluate the clinical results and determine appropriate methods of surgical treatment about type II talar neck fracture. MATERIALS AND METHODS: Among nineteen patients who received surgical treatment for type II talar neck fracture from May 2000 to May 2005. Fourteen patients with a follow-up period of more than 1 year were divided into two groups. Six patients reduced by closed reduction (Group A) with screw fixation and eight patients reduced by open reduction with screw fixation. We analyzed preoperative, postoperative and follow-up simple radiographs and reviewed patient hospital records retrospectively. Clinical results were evaluated by Hawkins scoring system. We analyzed pain, limp, range of motion of ankle and subtalar joint. RESULTS: Five patients (83.3%) in group A and seven patients (87.7%) in group B had excellent and good clinical results. There were no complications including avascular necrosis, delayed union, nonunion. CONCLUSION: Closed reduction with screw fixation of talar neck fracture shows correct reduction and satisfactory results. But because of short term period of follow-up, we need long term results.

STUDY DESIGN: Thirty-seven patients with spinal tuberculosis were evaluated according to surgical method. OBJECTIVES: To evaluate the effectiveness of posterior spinal instrumentation in the surgical treatment of patient with tuberculous spondylitis. SUMMARY OF LITERATURE REVIEWS: There are many debates about the effectiveness of posterior spinal instrumentation combined with anterior interbody fusion in tuberculous spondylitis. MATERIALS AND METHODS: From January 1995 to June 2000, 37 patients were divided into two groups depending on their use of posterior spinal instrumentation. Group I consist of thirteen patients who were treated with conventional anterior corpectomy and anterior interbody fusion using autogenous strut bone graft. Group II was composed of twenty-four patients who were treated with conventional anterior corpectomy and anterior interbody fusion combined with posterior spinal instrumentation. Changes of corrected kyphotic angle and complication were measured using pre-, post-operative and follow-up radiographs and chart review. RESULTS: In group I, six cases (46.2%) showed loss of corrected kyphotic angle. Of these six cases, five cases had initial kyphotic angle of more than 20 dgree and three cases had involvement of two or more vertebrae. All six cases had thoracic or thoracolumbar involvement. Comparing two groups, maintaining corrected kyphotic angle and low complication rates were obtained in group II during follow-up period. The change of deformity as followed. In thoracic area, the mean kyphotic angle of 26.5 dgree was reduced to 18 dgree postoperatively, At the most recent follow-up, the mean kyphotic angle was 31.5 dgree in group I, a loss of correction of 13.5 dgree . In group II, the mean kyphotic angle was corrected from 27 dgrees to 13.5 dgree after surgery. At the most recent follow-up, the mean kyphotic angle was 17.5 dgrees, a loss of correction of 4 dgree . CONCLUSION: Posterior spinal instrumentation combined with conventional anterior corpectomy and anterior interbody fusion were found to be effective for preventing loss of kyphotic angle and for maintaining stable bone fusion in patients with mean
