PURPOSE: The purpose of this study is to investigate the relative surgical risk and problems in hip hemiarthroplasty for treatment of an unstable intertrochanteric fracture in elderly patients over 80 years old. MATERIALS AND METHODS: Between April 2005 and May 2010, 58 patients whose age was over 80 years were available for inclusion in this study. They were divided into two groups: group 1 included 30 patients with femoral neck fracture and group 2 included 28 patients with intertrochanteric fracture. No significant differences in average age, concomitant disease, and walking ability before development of fracture were noted between the two groups. The following factors, including interval from development of fracture to operation, operation time, amount of blood loss, start time of walking after operation, duration of hospital stay, complications, revision rate, and walking ability were compared between the two groups. RESULTS: Operation time was an average of 85.2 minutes in group 1 and 97.5 minutes in group 2(P=0.03). The amount of bleeding was an average of 483 cc in group 1 and 695 cc in group 2(P=0.006). Similar results for walking start and recovery of walking ability after operation were observed in the two groups. No significant differences were observed in duration of hospital stay, complications, and revision rate. While 25 patients in group 1(83.3%) showed restoration of walking ability after operation to the same level of walking before injury, 19 patients in group 2(67.8%) showed restoration of walking ability postoperatively. CONCLUSION: Even though patients in group 2 showed a longer operation time and a higher amount of blood loss, compared with those in group 1, patients in group 2 had similar surgical risk and complications, compared with those in group 1. Therefore, primary hip hemiarthropalsty could be a good treatment option for intertrochanteric fracture in elderly.

Recent studies suggest that apolipoproteins may be better predictor of ischemic heart disease than are plasma lipids, such as total cholesterol and high density lipoprotein cholesterol(HDL-C). To examine this hypothesis, plasma levels of major lipids and major apolipo-proteins were measured and their derivatives were calculated in 30 male patients with ischemic heart disease(16 angina pectoris and 14 old myocardial infarction) and 30 age-matched male healthy controls. Plasma levels of lipids were obtained by conventional methods and apolipoproteins by Rocket immunoelectrophoresis. Levels of HDL-C, HDL2-cholesterol(HDL2-C), and apolipoprotein-AII, and ratios of HDL-C/total cholesterol, HDL2-C/total cholesterol, and apolipoprotein-AI/apolipoprotein-B were lower in the group of patients than in controls. Levels of low density lipoprotein cholesterol(LDL-C) and apolipoprotein-B, and ratios of lDL-C/HDL-C and apolipoprotein-AI/apolipoprotein-AII were higher in the group of patients. There were no statistically significant differences in the levels of total cholesterol and apolipoprotein-AI between the two groups. Stepwise discriminators analysis showed that apolipoprotein-B and apolipoprotein-AII were better discriminators than plasma lipids for identifying those with ischemic heart disease. One could correctly classify 78% of the cases by using the levels of the two apolipoproteins. By using the level of apolipoprotein-B, one could correctly classify 73% of the cases. There were no correlations between the levels of total cholesterol and HDL-C in the controls whereas there were positive correlations between the levels in the group of patients. In conclusion, this study showed that apolipoprotein-B was the best single discriminator for identifying the patients with ischemic heart disease, followed by apolipoprotein-AII.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.

The Di(a+b-) phenotype is extremely rare among Caucaclans and mostly confined to mongoloids. The incidences of Di antigen among Koreans were reported to be 6.1 to 14.5%, with an average of 9.6%; it can be calculated that the frequency of Di(a+b-) is 0.25% on the average. Authors report the first case of hemolytic disease of the newborn due to anti-Dib in Korea. The Diego phenotypes of the mother, baby and father were Di(a+b-), Di(a+b+) and Di (a-b+), respectively. The mother's serum and eluate from infant's erythrocytes contained anti-DP antibody active in the antiglobulin phase. After transfusions of Di-negative red cells from the mother and mother's relative, the patient was recovered from anemia and jaundice.

A subperiosteal ganglion has been very rarely reported, since Ollier reported first one in 1864. A subperiosteal ganglion is produced by mucoid degeneration and cyst formation within the periosteum, which results in cortical erosion. The characteristic plain radiolographic appearance of irregular cortical erosion and scalloping, with reactive periosteal bone spicules, has been considered pathognomonic of subperiosteal ganglion. Magnetic resonance imaging is performed to further characterize the soft tissue component of the mass. As in our patient, the characteristic signal intensities of magnetic resonance imaging are especially useful in identifying the lesion as a ganglion and in defining the lobular nature and the anatomical extent. We report here the case of a 35-year-old female who had a sudperiosteal ganglion of the distal radius.

Although a popliteal cyst is most commonly identified as an asymptomatic mass occurring just below the popliteal fossa, the fluid may further extravasate into a deep compartment, causing compression with symptoms of local pain and tenderness. When the popliteal vein is compressed by a popliteal cyst, it may develop the symptom simulating the deep vein thrombosis, when the popliteal artery is compressed, it may develop the symptom simulating the ischemic pain and intermittent claudication. It is unusual for popliteal cysts to involve a nerve. When such does occur, it usually involves the tibial nerve, very rarely the peroneal nerve. It is important to diagnose a popliteal cyst early and to differentiate it from a ganglionic cyst, thrombophlebitis or a popliteal aneurysm, to effect optimal therapy and to obviate a potential neuropathy. We are now reporting a case of a thirty four-year-old male who had a popliteal cyst causing tibial nerve compression.

The gastric polyps may be premalignant lesions and they should be removed as possible. The gastric polyps can be remoued by various endoscopic methods. The safety and therapeutic effectiveness of snare polypectomy, neodymium YAG laser therapy and electrocutery were compared in a total number of 106 patients who were diagnosed as benign polyps by means of endoscopic biopsy.Safety was evaluated by the rate of complications such as perforation and bleeding, and therapeutic effectiveness was evaluated by the average numbers of treatment session of each modality. Average numbers of treatment session of snare polypectomy, laser therapy and electrocautery were 1.04, 1.38 and l.44, respectively. Average numbers of treatment session of snare polypectomy were significantly (p<0.05) lower than those of other two methods. Perforation was not occurred in any group. Bleeding rates after snare polypectomy, laser therapy and electrocautery were 17.4%, 1.0% and 3.8%, respectively. Bleeding was significantly (p<0,05) more frequent after snare polypectomy than after other two methods. In conclusion therapeutic effectiveness was best in snare polypectomy but complication was most frequent after snare polypectomy. There was no difference between laser therapy and electrocautery for therapeutic effectiveness and safety. Therfore, laser therapy and electrocautery caa be used for the removal of flat adenoma, alternatively.
