OBJECTIVES: This study was conducted to develop a Korean version of the Participatory Action Oriented Training (PAOT) program and training materials for improvement of agricultural working environments. METHODS: The PAOT manual and checklist were developed on the basis of the original English version of the training materials, a questionnaire survey of agricultural health and safety professionals, and a brainstorming conference. Good example pictures were collected through visits to agricultural workers' houses, and an easily understandable picture was drawn by an animation specialist. A PAOT action manual and five types of action checklists were developed for use in different agricultural environments. Each action checklist contained six categories and 38 items of agricultural health and safety principles; the six categories were material storage and handling, work stations and tools, machine safety, physical environment, working schedule and organization, and basic health and safety management. Incorporating these training materials, a one-day Korean PAOT program was developed. RESULTS: Among 307 candidate agricultural workers from four rural Korean villages, 94 workers (59 males, 35 females) participated in a PAOT from July 2007 to Oct 2008. The PAOT program was successful and the mean self-estimated satisfaction score of the participants was greater than 90%. CONCLUSIONS: A Korean PAOT program and training materials were successfully developed and applied to Korean agricultural workers. Although more studies are needed, it is expected that PAOT will greatly contribute to the improvement of agricultural working conditions and health and safety through the use of agricultural workers' self initiatives.

OBJECTIVES: Recently the care of cerebrovascular and cardiovascular disease is important as much as that of cancer care in public health, so the control of diabetes mellitus(DM) which is a risk factor of cerebrovascular and cardiovascular disease has been also important consideration. This study was carried out to investigate the blood glucose change of the participants in diabetes mellitus class(DM class) of a health center. METHODS: Study subjects were 54 participants of DM class in a health center that had been held once a month, from January 2005 to March 2006. RESULTS: Among the DM class participants, 67.3% participated by 50% or over in the DM class. After DM class, the level of random blood sugar decreased from 176mg/dl to 156mg/dl in DM class participants(p<0.05). In a comparison between more than 50% participation group and less than 50% participation group, more than 50% participation group got decreased level of blood sugar from 182mg/dl to 155mg/dl and less than 50% participation group also got decreased level from 172mg/dl to 156mg/dl. But there was no statistically significant difference between two groups. CONCLUSION: DM class of health center was effective program to manage diabetes mellitus patients in community.

Arotinolol was administered orally to 31 patients to evaluate is antihypertensive action. After one week of antihypertensive medication, they were given Arotinolol 30mg daily for 4 week. Routine serum chemistries, electrolytes, urinalysis and electrocardiography were studied before and after Arotinolol. Blood pressure measured in sitting, supine and standing position was 175.3+/-5.4/115.7+/-4.0, 168.0+/-5.2/150.0+/-3.8, 154.4+/-8.5/103.4+/-3.2mmHg in control and 143.8+/-2.8/93.3+/-2.8, 144.6+/-5.4/88.1+/-4.3, 139.7+/-4.6/86.8+/-3.4mmHg in Arotinolol treatment group. The differences between both blood pressure were statistically significant(P<0.01). No laboratory test showed significant difference between both period. There were no significant side effects except 2 cases of transient headache and dizziness respectively, and one case of diarrhea. In summary, Arotinolol apears to reduce blood pressure effectively with minimal side effects.

Hypoglycemia sometimes manifests as focal neurologic deficits simulating cerebrovascular disease. Symptoms are usually resolved by glucose infusion, but persistent hemiplegia is rarely reported. A 68-year-old diabetic woman on oral hypoglycemic agent(OHA) was admitted with right hemiplegia and global aphasia. Blood glucose level was 29 mg/dl on admission. No evidence of cerebral infarct or underlying brain disease could be found on initial brain CT and follow up MRI. Focal stenosis or occlusion was also absent on MR angiography. Hemiplegia and aphasia were not improved despite adequate therapy. Hypoglycemic hemiplegia should be suspected in all diabetic patients using insulin or OHA with stroke-like episode, and we suggest that prolonged hypoglycemia may be related to persistence of neurologic deficits.

OBJECTIVES: To compare results of 4 different extraction methods in laparoscopic management of dermoid cyst. STUDY DESIGN: This article is a retrospective, multicenter study for 247 patients with benign dermoid cyst in period of 1995-1998. Dermoid cyst was extracted by Endopouch (99 cases), puncture-irrigation-extraction (69 cases), colpotomy (35 cases), and dermoid cyst as a "pouch bag" (44 cases). RESULTS: We analyzed irrigation amount, operative time, postoperative hospital stay and complications by four different extraction methods. Endopouch extraction method needed less amount of irrigation fluid for cleaning the abdominal cavity and had a shorter postoperative hospital stay (ANOVA, p=0.0001). There were no significant differences in operative times among groups. There were four cases of morbidity in puncture-irrigation-extraction method (6%), three had fever (> 38degrees C) and one intraabdominal abscess. One incisional hernia was noted in "pouch bag" method (2%). CONCLUSIONS: We recommend minimal spillage method for extraction of dermoid and careful irrigation of abdominal cavity to prevent potential risk of chemical peritonitis such as Endopouch, "pouch bag", and colpotomy with the exception of puncture-irrigation-extraction method.

Voltage dependent calcium channel (VDCC), one of the most important regulator of Ca2+ concentration in neuron, play an essential role in the central processing of nociceptive information. The present study investigated the antinociceptive effects of L, T or N type VDCC blockers on the formalin-induced orofacial inflammatory pain. Experiments were carried out on adult male Sprague-Dawley rats weighing 220-280 g. Anesthetized rats were individually fixed on a stereotaxic frame and a polyethylene (PE) tube was implanted for intracisternal injection. After 72 hours, 5% formalin (50 microL) was applied subcutaneously to the vibrissa pad and nociceptive scratching behavior was recorded for nine successive 5 min intervals. VDCC blockers were administered intracisternally 20 minutes prior to subcutaneous injection of formalin into the orofacial area. The intracisternal administration of 350 or 700 microg of verapamil, a blocker of L type VDCC, significantly decreased the number of scratches and duration in the behavioral responses produced by formalin injection. Intracisternal administration of 75 or 150 microg of mibefradil, a T type VDCC blocker, or 11 or 22 microg of cilnidipine, a N type VDCC blocker, also produced significant suppression of the number of scratches and duration of scratching in the first and second phase. Neither intracisternal administration of all VDCC blockers nor vehicle did not affect in motor dysfunction. The present results suggest that central VDCCs play an important role in orofacial nociceptive transmission and a targeted inhibition of the VDCCs is a potentially important treatment approach for inflammatory pain originating in the orofacial area.

STUDY DESIGN: Retrospective review of the results of somatosensory evoked potentials (SSEP) performed in cervical spine surgery. PURPOSE: To evaluate the utility of spinal cord monitoring during cervical spine surgery in a single surgeon's practice, based on how often it prompted an intraoperative intervention. OVERVIEW OF LITERATURE: Intraoperative monitoring during cervical spine surgery is not a universally accepted standard of care. This is due in part to the paucity of literature regarding the impact of monitoring on patient management or outcome. METHODS: SSEP for tibial, median, and ulnar nerves were monitored in 809 consecutive cervical spine operations performed by a single surgeon. The average patient age was 52 years (range, 2 to 88 years), with 472 males and 339 females. Cases were screened for significant degradation or loss of SSEP data. Specific attention was paid to 1) what interventions were performed in response to the SSEP degradation with subsequent improvement, and 2) whether SSEP changes corresponded with postoperative neurological deficits. RESULTS: Seventeen of 809 patients (2.1%) had SSEP degradation that met warning criteria and therefore prompted intervention. Release of shoulder tape (8) or traction (4) most often resulted in SSEP improvement. Failure of SSEP data to return to within acceptable limits of baseline was associated with neurological deficit (p=0.04). Two patients awoke with new postoperative neurological deficits, which resolved in 6 hours and 2 months respectively. Patients with ossification of the posterior longitudinal ligament (OPLL) were at seven-fold greater risk of intraoperative SSEP degradation. CONCLUSIONS: SSEP monitoring in this surgical population proved sensitive to perioperative factors which may increase the risk of postoperative neurologic deficit, and probably prevented neurological deficits in 15 of 809 patients (1.9%). Improvement in data following intervention appears to correlate well with unchanged neurologic status. Experience with intraoperative monitoring in this patient series has led to incorporation of these techniques as a standard of care in cervical spine surgeries performed by this surgeon.

BACKGROUND: The Cordis coronary stent is a flexible, balloon expandable, radiopaque tantalum stent. Previous reports have shown excellent initial clinical outcomes. To our knowledge, there is no report of the long-term clinical outcomes. The intensely radiopaque tantalum may interfere with the angiographic assessment. We intended to evaluate long-term clinical and angiographic restenosis rates after successful implantation of the Cordis tantalum coronary stent. METHOD: Two hundred and eighty-five consecutive patients with 300 lesions were treated with 366 Cordis stents. An angiographic follow-up substudy was performed in 190 lesions ; 6 month follow-up angiograms were available in 167(88%). At follow-up, intravascular ultrasound(IVUS) was performed to (1) determine the pattern of restenosis and (2) to validate the quantitative coronary angiographic(QCA) caliper measurements. RESULTS: IVUS and QCA caliper measurement of minimal luminal diameter correlated reliably (r=0.767, p<0.001). The QCA analysis detected diffuse in-stent restenosis more reliably than focal in-stent restenosis(p<0.01). The overall angiographic restenosis rate was 19%, The factors affecting angiographic restenosis were post-stent minimum lumen diameter, type C lesion, and reference vessel size. CONCLUSION: We concluded 1) The angiographic restenosis rate of Cordis stent was comparable to that of other slotted-tube stent. 2) The QCA caliper method is reliable for the assessment of Cordis in-stent restenosis, especially in the detection of diffuse in-stent restenosis. However, QCA may miss focal in-stent restenosis only detectable by IVUS

BACKGROUND: Recently, several reports regarding the protected and/or unprotected left main stenting suggested the possibility of percutaneous intervention for this prohibited area. We intented to evaluate immediate and long-term outcomes after elective stenting of unprotected left main coronary artery in selected patients. METHOD: Forty eight consecutive patients with unprotected left main coronary artery stenosis and normal left ventricular function were treated with stents implantation. The poststent antithrombotic regimen were aspirin, ticlopidine with warfarin in 14 pateints or without warfarin in 34 patients. The stents for left main coronary artery stenosis were Palmaz-Schatz stent in 25, NIR stent in 8, Multi-link stent in 3, Cordis stent in 7, Palmaz stent in 2, Gianturco-Roubin stent II in 2, and Microstent in 1 patient. Intravascular ultrasound was performed in selected patients before predilation and after stenting at late stage of this study. RESULTS: The procedural success rate was 100%. Regardless of anticoagulation, the in hospital complication including stent thrombosis, myocardial infarction, emergency bypass surgery and death did not occur. Six-months follow-up angiography was performed in 31 patients(82%) of 38 eligible patients. The angiographic restenosis occurred in 7 patients(22%) who subsequently underwent elective coronary bypass surgery in 5 patients and rotational atherectomy/balloon angioplasty in 2 patients. The target lesion revascularization rate was 18%. One death(3%) occurred 2 days after elective coronary bypass surgery during follow-up period. CONCLUSION: Stenting of unprotected left main coronary artery stenosis might be a safe and effective alternative to bypass surgery in carefully selected patients with normal left ventricular function. However, further clinical study should be needed for the late outcomes with larger numbers of patients.
