Heterotopic ossification(HO) is a frequent complication of total hip arthroplasty(THA), If it is sevre enough, it can convert a successful result of the operation into a poor one. Among several strategies that researches in recent years have tested, radiation therapy have been accepted to have efficacy for prevention of heterotopic ossification by many authors. While postoperative irradiation has been shown to lower the incidence of HO effectively in high risk patients following THA, patients in multiple dose protocols continue to develop some heterotopic ossifiction despite therapy and have some problems. Ninteen patients received single dose exposure to 600 rad delivered within 48 hours of THA with shielding of prosthesis region. The patients were considered high risk group for developing HO because of hypertropic osteoarthritis, post-traumatic osteoarthritis or the presence of previous formed ectopic bone. The average follow up period was 10.2 months(range 6 months

A 32-year-old housewife who resides in Taegu was admitted in Yeungman University Hospital due to right upper quadrant abdminal pain of 2 mounths'duration. An abdomical CT and ultrasonography revealed a relatively well demarcated low density mass in the right lobe of liver. Right hepatic lobectomy was performed on the clinical impression of hepatoma. On the light microscopic study, the lobulated liver mass showed extensive central necrosis and fibrosis, with large numbers of pseudotubercles therein. The pseudotubercles have distorted helminthic eggs frequently. The submitted common bile duct lymph node also showed a few pseudotubercles. The eggs recovered from the tissue homogenate measured 140~152 micrometer by 75~85 micrometer in size and were unembryonated and light yellow to brown. The eggs were determined as those of Fasciola species. We reported the present case as 11th one of human fascioliasis in korea.

BACKGROUND: We investigated the risk factors for the recurrence of anterior shoulder instability after arthroscopic surgery with suture anchors and the clinical outcomes after reoperation. METHODS: A total of 281 patients (February 2001 to December 2012) were enrolled into our study, and postoperative subluxation and dislocation were considered as recurrence of the condition. We analyzed radiologic results and functional outcome including the American Shoulder and Elbow Surgeons Evaluation Form, the Korean Shoulder Society Score, and the Rowe scores. RESULTS: Of the 281 patients, instability recurred in 51 patients (18.1%). Sixteen out of 51 patients (31.4%) received a reoperation. In terms of the functional outcome, we found that the intact group, comprising patients without recurrence, had a significantly better functional outcome than those in the recurrent group. The size of glenoid defect at the time of initial surgery significantly differed between intact and recurrent group (p<0.05). We found that the number of dislocations, the time from the initial presentation of symptoms to surgery, and the number of anchor points significantly differed between initial operation and revision group (p<0.05). The functional outcome after revision surgery was comparable to intact group after initial operation. CONCLUSIONS: Eighteen percent of recurrence occurred after arthroscopic instability surgery, and 5.6% received reoperation surgery. Risk factors for recurrence was the initial size of glenoid defect. In cases of revision surgery, good clinical outcomes could be achieved using additional suture anchor.

BACKGROUND: We studied the incidence of trauma caused by alcohol related accidents, and the effects that has on the occurrence, the extent, and the outcome to the patient. METHODS: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of january 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were divided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analysed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. RESULTS: The total of the trauma patients, added up to 832 people, 577: male and 255: female. Among this sum, 16 trauma patients were alcohol related(male:127 & female 36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mossy by fast-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer alcohol-related trauma patients. CONCLUSION: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time it the reason for their visit were mossy because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

BACKGROUND:Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates (100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR. METHODS:This is a prospective, randomized, crossover observational study using a RespiTrainer?r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate (1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive (total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks (1.0 to 1.2 seconds depending on the rate of metronome) and deflate the bag over 2 ticks. The sequence of three different metronome rates was randomized. RESULTS:Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute (343±84 mL vs. 294±90 mL, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute (18.7 vs. 21.6 mmHg, P=0.006). CONCLUSION:In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR.

Although the method to obtain a good results of treatment is still controversial in ankle fracture, most authors agree with open reduction and internal fixation for unstable ankle fracture. They also emphasize the importance of accurate reduction and rigid fixation of fractured lateral malleolus. Recently, the good results of early weight bearing and joint motion has been recognized. Therefore the cast immobilization for long duration is eliminated after surgery by many authorities. In addition to positive role of early ankle motion and weight bearing, we could expect the advantage of subsidence of stiffness, osteoporosis, and early returning to social activity. The seventy-eight unstable ankle fractures treated at Severance Hospital, Yonsei University College of medicine with open reduction and internal fixation were analyzed in clinical and radiological aspects. The following results were obtained. 1. In unstable ankle fracture, the good functional results were obtained with early joint motion and weight bearing after accurate reduction and rigid fixation. 2. The accurate reduction and rigid fixation for lateral malleolar fracture was the most significant factor in contributing to good results. 3. Syndesmotic ligament should be examined on each exploration of fractured fibular. In spite of the immediate weight bearing, the transfixion screw has remained in place without loosening or breakage. 4. The reduction of medial malleolar fracture was relatively easy and seems not to affect the results.

Purpose: To investigate the extent of bone ingrowth into the porous-coated acetabular cups as well as the factors that correlated with bone ingrowth in total hip arthroplasty. Materials and Methods: Thirty six Harris-Galante porous-coated acetabular cups that were retrieved through revision surgery were examined in this study. Acetabular cups retrieved due to infection or severely destroyed cups (ed note: severe what?) were excluded. The extent of bone ingrowth into the acetabular cups was grossly measured, and its correlation with the variables including age, gender, weight, height, the duration of fixation, size, number of screws, inclination and anteversion was statistically analyzed. Results: The mean proportion of bone ingrowth was 52.9 21.9%(2~90%) and less than 30% in three cups(8.3%). The pattern and the location of bone ingrowth were not consistent. There was no correlation between the extent of bone ingrowth and age, gender, weight, height, the duration of fixation, cup size, number of screws, size, inclination and anteversion. Conclusion: Harris-Galante porous-coated acetabular cups showed satisfactory bone ingrowth regardless of the variables associated with the demographic or surgical conditions. Surface treatments with a fiber-metal porouscoating appears to be suitable for cementless acetabular cups in terms of the long term results.
