The intra-articular osteochondroma arising from soft tissue is very rare and has been reported less than a dozen cases in the English literature. This tumor is the result of extrasynovial metaplasia of the fibrous capsule or of the adjacent connective tissue of a joint. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 37 year-old man which arised from the medial meniscus. Histology as well as gross findings were consistent with osteochondroma. Excision of the mass with attached meniscus relieved symptoms. No recurrence, or malignant change was identified up to 1 year after excision.

OBJECTIVE: We compared patients with chronic schizophrenia and normal controls with respect to decision-making ability. Measures were implemented to control for the participants' intelligence levels as well as to ensure to use of a moderate sample size. The goal of this study was to confirm inconsistent results from previous studies which had stemmed from too small of a sample size, highly variable performance of normal controls, and not controlling for intelligence as a confounding factor. METHODS: Fifty-two chronic stable schizophrenic inpatients and 55 healthy controls participated in the study. We controlled for intelligence by including subjects with intelligence quotient's (IQ) between 80 and 120, examining any differences in decision-making performance between groups on the Iowa Gambling Task (IGT). We also addressed several issues relating to performance on the IGT, such as working memory and clinical symptoms. RESULTS: Schizophrenic patients were found to perform poorly on the IGT relative to normal controls (F(1,105)=17.73, p<0.001); however, more importantly, they also displayed the slow yet profitable shift from disadvantageous decks to advantageous decks over time. We also found that when compared with healthy controls, schizophrenic patients showed a poorer performance on the Wisconsin Card Sorting Test (WCST)(t=-5.48, p<0.001 for perseverative error) which was not related to their performance on the IGT. CONCLUSION: Based on previous literature and the results of this study, impaired sensitivity to both reward and punishment might be a more plausible explanation for the poor performance on the IGT in the schizophrenic group. We speculated that this impairment seemed related more to the different responsiveness to the magnitude than to the frequency of punishment, and to the different interpretation of less informative verbal cues in the context of the reinforcing schedule.

188Re (beta=22 MeV; gamma=155 keV; T1/2=16.9 hours) is an attractive therapeutic radioisotope which is produced from decay of reactor-produced tungsten-188 parent (T1/2=69 days). 188W has been produced from the double neutron capture reaction of 186W. 188Re can be easily obtained by elution of saline on alumina based 186W/188Re generator, which is commercially available. Complexes labelled with 188Re have been developed for the radiotherapy treatment of diseases because of the desirable nuclear properties of the radioisotope and it's chemical properties similar to those of technetium, a well established diagnostic agent.

The "flosting knee" is the term applied to the flail knee joint segment resulting from a fracture of the shaft of adiacent metanhysis of the ipsilateralfemur and tibia. The various methods of treatment of the "floating knee" were adapted by many authors according to degree of the comminution, degree of the soft tissue injury, general condition state of the fracture. Authors experienced the floating knee in 52 cases on 51 patients who were treated at Soon Chun Hyang University Hospital in the period of 4 years and 5 months from January 1985 to June 1989 and among them, 45 cases were treated by operative method and 7 cases by conservative methods at least one of the femur and tibia, The results were as follews;1. Floating Knee occured six times more in male and the peak age was third and fourth decades. 2. The most common cause of fractures was traffie aecident and there was difficulty in diagnosis of ligamentous disruption of the ipsilateral knee. 3. The common fracture site were middle one third and the most common fracture shape was comminuted in both femur and tibia. 4. A good or excellent functional result was aohieved in treated with open reduction and rigid fixation of both fracture and there were no significant difference in group of the internal fixation of both femur and tibia. 5. Intramedullary nailing on the femur and plate fixation on the tibia provided rigid fixation of fracture and the it made possible early joint motion exercise and ambulation and the average healing time of fracuture was much shortened. 6. The most common concomitant injury were soft tissue injury and delayed or nonuion and osteomyelitis were developed more frequently in the plate and screw fixation group of the open fracture.

PURPOSE: Body fluid status of patients in an emergency room environment is a very important parameter during clinical evaluation. In this study, we wanted to know the relationship between the diameter of the inferior vena cava and the diameter of the (IVC/Ao index) and central venous pressure (CVP) in hemodynamically unstable patients. METHODS: This study was done prospectively in an emergency medical center of a hospital from January to August, 2009. We compared the diameter of the IVC, the diameter of inferior vena cava/the body surface area index (IVC/BSA index), the IVC/Ao index, and other variables. Before and after hydration of patients with a systolic blood pressure less than 90 mmHg and who had a central venous catheter in place. Then, we calculated the correlation coefficient for DeltaCVP, DeltaIVC/Ao index, and other indexes. RESULTS: Fifty-nine patients were enrolled in the study. The mean IVC diameter before hydration was 14.3+/-2.7 mm; it was 15.6+/-2.7 mm after hydration (p<0.01). The IVC/BSA index before hydration was 8.75+/-1.72 and 9.55+/-1.79 after hydration (p<0.01). The IVC/Ao index before hydration was 1.08+/-0.23; it was 1.16+/-0.25 after hydration (p<0.01). The correlation coefficient for DeltaCVP and DeltaIVC was 0.37 (p<0.01); for DeltaCVP vs. the DeltaIVC/BSA index it was 0.37 (p<0.01); for the DeltaIVC/Ao index it was 0.27 (p=0.04). CONCLUSION: CVP has a higher correlation to IVC diameter and to IVC/BSA index than to the IVC/Ao index. Hence, we should estimate the IVC/Ao index and use that estimate along with other indexes to evaluate body fluid status when dealing with hemodynamically unstable patients.

We evaluated the antihypertensive effect of amlodipine, a calcium channel bloker, in 35 cases of essential hypertention. After 12 weeks' administration(5~10mg q.d.), the following results were obtained : 1) The systoloic and diastolic blood pressure were decreased significantly(170.3+/-12.2mmHg vs 143.7+/-13.0mmHg p<0.01 and 104.7+/-5.9mmHg vs 87.8+/-6.5mmHg, p<0.01, respectively) but the heart rate was independant of amlodipine administration. 2) The systolic blood pressure was lowered by 20mmHg or more in 26(76.5%) of 34 patients and the diastolic pressure was lowered by 10mmHg or more in 26(76.5%) of 34 patients at 12 weeks after amlodipine administration. 3) The adverse effects of amlodipine were dizziness in 5, edema in 5, indigestion in 3, constipation in 2, headache, flushing, insomnia in 1 patient respectively and only one of them discontinued amlodipine administration due to severs facial flushing and skin eruption.

OBJECTIVES: Sound and light (SL) stimulation has been used as a method to induce some useful mental states in the fields of psychology and psychiatry. It is believed that sound and light entrainment device (SLED) has some specific effects through synchronization of EEG in patients who use it. Theta frequency is believed to stimulate deep relaxation and short term memory processing. This study was conducted to evaluate if 4-10Hz SL stimulation can induce relaxation and improve short term memory function. METHODS: Ten medical students with no medical or psychiatric problems participated in this study. Subjects were randomly divided into two groups. One group was applied with real SLED was applied to one group (R group) and pseudo SLED to the other group (P group). The two groups were exposed to SL stimulation with SLED 15 minutes a day for 5 days, and after two days rest the two groups were switched over. The Korea Wechsler Adult Intelligence Scale (K-WAIS), Academic Motivation Tests (AMT), Test Anxiety Scale (TAS), Korea Auditory Verbal Learning Test (K-AVLT), and digit span were used to evaluate short term memory. Spielberger's State-Trait anxiety inventory and heart rate variability (HRV) test were used to evaluate degree of relaxation. RESULTS: Compared with S group, R group showed a significant improvement in K-AVLT and digit span after a single application of SL stimulation. But 5-day long application did not reveal any differences between the two groups. A significant change in HRV was observed in 5-day long application of SL stimulation after being switched over to other SLED. CONCLUSION: This pilot study suggests that 4-10Hz SL stimulation has some positive influences on short term memory and relaxation.
