BACKGROUND: Various kinds of methods had been tried to reduce pain on injection of propofol. In this study, the effect of lidocaine pretreatment and that of temperature controlled injections were compared and evaluated its clinical utility. METHODS: One hundred and twenty patients were randomly allocated into 4 groups after permission. Room temperature propofol was used as induction agent in group P,. In group C, cooling (4 degrees C) propofol was used and warming propofol (37 degrees C) in group H. And room temperature propofol following lidocaine (1 mg/kg) was used in group L. Injection dosage of propofol was 2 mg/kg and injection speed was 2 ml/sec in all groups. In each patients, pain score and visual analog scale were measured and tested by ANOVA or Kruskal-Wallis test. RESULTS: There were no statistical significant difference in pain score among the 4 groups. But in visual analog scale analysis, group L markedly reduced values than the other groups by statistically significant manner (in Duncan grouping). CONCLUSION: The alleviating effect of lidocaine pretreatment on painful injection was better than that of changing temperature of propofol itself. More over effectiveness, in view of simplicity, we recommend lidocaine pretreatment.

Rectus sheath hematoma of the abdominal wall is a well-recognized, but uncommon condition, caused by a tear in an epigastric vessel and characterized by sudden onset of severe abdominal pain and palpable mass. In most cases, a precipitating cause can be demonstrated. Causes include external trauma, strenuous activities, coughing, lifting, sneezing, vomiting, straining while urinating or defecating, golfing, pregnancy and the puerperium, anticoagulation therapy, infection, chronic diesase, arteriosclerosis, hypertension, prior paracentesis or laparotomy, inadequate hemostasis or excessive retraction in surgery, and idiopathy. Unfortunately, the correct diagnosis often is missed, and the hematoma is found only during an exploratory laparotomy. Treatment should be conservative in most instances. Although the mortality rate for patients with rectus sheath hematoma is low, the condition may be fatal if the volume of the hemorrhage is large and if treatment is delayed. Hence, it should be included in the differential diagnosis of any patient who presents to the emergency department with acute onset of abdominal pain. Our purpose is to familiarlize emergency physicians with the pathophysiology, the diagnosis, and the treatment of rectus sheath hematoma. We describe a patient with fatal rectus sheath hematoma presenting to the emergency department and give a review of the literature.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

BACKGROUND: Ischemic preconditioning(a prior short period of coronary artery occlusion) has been known to have protective effects on ischemia-induced myocardial injury. The purpose of this study was to investigate the effects of hypoxic preconditioning or ischemic preconditioning on the
