BACKGROUND: Selective 2-agonists cause decrease in serum K+ concentration. Midazolam is an anxiolytic, sedative, and amnestic drug. Premedication of midazolam prevents increase of catecholamine with anxiety. Clonidine, alpha 2-adrenergic receptor agonist, supresses sympathetic outflow from central nervous system. So we can expect that premedication of clonidine or midazolam will prevent hypokalemia before induction of anesthesia. METHODS: Twenty two patients received 300 mcg clonidine per oral, 22 patients 0.05 mg/kg midazolan IM and 22 patients had no premedication. We measured serum K+ level at out-patient Department (T1), at 11:00 P.M. of the day before surgery (T2) and immediately before induction of anesthesia (T3). RESULTS: Serum K+ levels at T2 decreased compared to serum K+ level at T1 in all groups. Serum K+ levels T3 decreased compared to serum K+ level at T2 in control and midazolam groups but clonidine group did not decrease in serum K+ level. CONCLUSIONS: We can not prevent decrease of serum K+ level with premedication of midazolam but we can prevent decrease of serum K+ level with premedication of clonidine. So premedication of clonidine is more effective than midazolam in prevention of hypokalemia before induction of anesthesia.

Variant angina is characterized by spontaneous episodes of angina, usually occurring in the morning and having ST segment elevation on the electrocardiogram. However, in the case presented here, vasospasm and angina was shown by ergonovine without ST elevation. The patient was a 60-year-old man who presented with a 2-year history of frequent chest pain. There were no abnormalities in coronary angiography. When ergonovine (100 microg) was injected, total occlusion of the proximal right coronary artery was seen, without ST elevation at the electrocardiogram. The cause was collateral from left anterior descending artery to distal right coronary artery at the left coronary angiography. Therefore, in a patient with variant angina without ST elevation, a transient collateral circulation during vasospasm should be considered.

The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

Malignant pericardial mesothelioma is a rare and progressive cardiac tumor. There is no established standard treatment and the prognosis is poor. Most patients were retrospectively diagnosed from surgery or autopsy due to absence of specific clinical manifestation. Most patients with pericardial mesothelioma have demonstrated constrictive physiology on echocardiography or cardiac catheterization. Therefore, pericardial mesothelioma was often misdiagnosed as other causes of constrictive pericarditis. We report a case of primary pericardial mesothelioma misdiagnosed as pericardial metastasis of unknown origin.

Bortezomib is an inhibitor of 26S proteasome, which is an effective treatment for multiple myeloma. The common adverse effects of bortezomib are asthenic conditions, gastrointestinal disturbances, and peripheral neuropathy. Here we describe a patient with dyspnea and general weakness because of complete atrioventricular block while receiving bortezomib. We immediately stopped bortezomib, and after inserting a permanent VDD pacemaker, the patients' symptoms disappeared.

PURPOSE: The transcription factor, NF-kB, is important in the coordinated expressions of various pro-inflammatory and adhesion molecules. Our hypothesis is that inhibiting the action of NF-kB using a synthetic decoy oligodeoxynucleotide(ODN) can block the underlying inflammatory response in glomerulonephritis. MATERIALS AND METHODS: Forty two male C57BL6 mice, weighting 25g, were divided into four groups; in group 1, 2 mice were used as normal controls; in group 2, a unilateral ureteral obstruction(UUO) was induced in 12 mice; in group 3, 20 UUO mice were treated using ring-type NK-kB decoy ODN; and in group 4, 8 UUO mice were treated using scramble type NF-kB decoy ODN. The mice were killed 1, 3, 5 and 7 days after the NF-kB decoy ODN injections, and the blood urea nitrogen(BUN), and expressions of tumor necrosis factor-alpha (TNF-alpha), interleukin-beta(IL-beta), fibronectin, vascular cell adhesion molecule(VCAM) and monocyte chemotactic protein-1(MCP-1), as well as the histopathological findings, analyzed in each group. RESULTS: The serum levels of BUN, TNF-alpha, IL-beta, fibronectin, VCAM and MCP-1 were increased in group 2, but decreased in group 3. The histopathological findings of the kidneys in group 3 were most similar to those found in the control(group 1). CONCLUSIONS: NF-kB decoy ODN treatment substantially inhibited the disease, with reductions in the histological damage and the renal expressions of inflammatory cytokines.

PURPOSE: To evaluate the plain chest radiographic findings of smoke inhalation. MATERIALS AND METHODS:Our study included 72 burn patients who had suffered smoke inhalation. On admis-sion,all underwent serial portable chest AP radiography. We retrospectively reviewed the plain chest radi-ographs taken between admission and pootburn day five, evaluating the pattern, distribution, and time onset of direct injury to the respiratory system by smoke inhalation. The lesions were also assessed for change. RESULTS: In 16 of 72 patients (22%), abnormal findings of direct injury to the respiratory system by smoke in-halation were revealed by the radiographs. Abnormal findings were 15 pulmonary lesions and one subglottic tracheal narrowing. Findings of pulmonary lesions were multiple small patchy consolidations (10/15), peri-bronchial cuffing (8/15), and perivascular fuzziness (6/15). Patterns of pulmonary lesions were mixed alveolar and interstitial lesion (n=9), interstitial lesion (n=5), and alveolar lesion (n=1). No interlobular septal thicken-ing was observed. Pulmonary edema was distributed predominantly in the upper lung zone and perihilar re-gion, with asymmetricity. Its time of onset was within 24 hours in 13 cases, 24 -48 hours in two cases, and 48 -72 hours in one. Five of 16 patients progressed to ARDS. CONCLUSION: Chest radiographs showed that pulmonary lesions caused by inhalation injury were due to pul-monary edema, which the pattern of which was commonly mixed alveolar and interstitial.
