The radial head forms articulation with radial head fossa of proximal ulna and capitellum, and it ditectly contributes pronation and supination of forearm and also flexion and extension of elbow. There were debates in treatment of radial head fracture especially in displaced or communited fracture. From January 1982 to February 1992, we experienced and analysed 29 cases of radial head fracture. They were treated with conservative treatment or operative treatment according to type The results were as follows; 1. We could get better results with open reduction and internal fixation with miniscrew than radial head excision in type 11 radial head fracture. 2. There were unfavorable results of valgus instability, weakness in all cases of radial head excision.

BACKGROUND: Because of wide individual variations in response to sedative and the level of sedation desired by different patients, inadequate sedation is frequent during surgery. Patient-controlled sedation is a logical extension of patient-controlled analgesia to find and maintain their own steady-state of sedation by self-administration of sedatives during surgery. The purpose of this study was to evaluate the feasibility of patient-controlled sedation compared with anesthesiologist-controlled sedation during surgical spinal anesthesia. METHODS: Unpremedicated forty adult patients who received spinal anesthesia for lower extremity surgery were randomly allocated into two groups (n=20 for each group). After selection of target state of sedation according to sedation scale, patient-controlled sedation (PCS) group self-administered 0.5 mg (1 ml) intravenous midazolam in increments using a Walkmed PCA infusor and anesthesiologist- controlled sedation (ACS) group administered by the anesthesiologist as the same manner to achieve previously selected sedation state. Sedation score, vital signs, SpO2 were checked 5, 10, 20, 30, 40min after start of drug injection. RESULTS: The sedation scores patient desired were 4.4 +/- 0.8 in PCS group and 4.3 +/- 0.7 in ACS group. These scores were achieved 20min after start of injection in PCS group and 40 min in ACS grou p (p<0.05). Degree of satisfaction was higher in PCS group compared with ACS group (1.5 +/- 0.6 vs 2.1 +/- 0.8, p<0.05). No complications were detected in two groups. CONCLUSIONS: PCS using midazolam was better than ACS in terms of early achievement of sedation state patient desired and degree of satisfaction.

Systolic time intervals were studied in a total of 83 patients with pure or predominant isolated valvular heart disease. They consisted of three groups of patients : namely, 38 cases of mitral stenosis, 25 cases of mitral regurgitation and 20 cases of aortic regurgitation. The mean of the electromechanical systole was within normal ranges in all three groups, and threre was no significant difference between the groups. The mean of the left ventriclar ejection time was also within normal limits in all groups, as was that of the electromechanical systole, but it was significantly shorter in patients with mitral regurgitation than in the others, and was significantly longer in patients with aortic regurgitation. The mean of the pre-ejection period and the ratio of the pre-ejection period to the left ventricular ejection time were within normal ranges in patients with aortic regurgitation, whereas both parameters were significantly increased in patients with mitral stenosis or mitral regurgitation, particularly in the latter.

A 35-year-old man was admitted with a 20 day history of generalized edema and muscular weakness of the lower extremities. He was alert with a pale puffy face and an ejection murmur was heard at the cardiac apex. The electrocardiogram disclosed low voltage, first degree atrioventricular block, and a right bundle branch block. During the hospitalization an intractable diastolic hypotension developed, which measured 0 mmHg at the lowest point. At that time the echocardiogram revealed a dilated, akinetic right ventricle. Eventually a multiorgan failure developed and an autopsy following his death presented a fibrofatty replacement of the right ventricular myocardium. This might be a case of an arrhythmogenic right ventricular dysplasia/cardiomyopathy, which is usually characterized clinically by a ventricular tachycardia and may cause a sudden death in young adults.

A number of reports have documented that air-filled cavities in the body will expand if the gas within the space is less soluble in blood than the gas respired. Since an air inflated endotracheal tube cuff within the trachea represents an air-filled body cavity the intracuff gas volume and pressure may be altered during general Inhalation anesthesia. This study was conducted to determine the degree of intracuff pressure and volume changes during general anesthesia. The results were as follows; 1) Twenty three patients, ranging in age from 17 to 73 years, in ASA physical status class 1.ll were reviewed. There were 9 male and 14 females with 19 cases from the general surgical department and 4 from the gynecological department. 2) The duration. of annesthesia ranged was from 120 to 205.7m minutes. 3) Significant intracuff pressure changes develeped in Groups IA and IB (p <7.75), and a significant difference was noted between group 1 and 2. 4) Intracuff gas volume was increased in Groups IA (50% 02, 50% N27) and 1B (33.3% 02, 66.7%N20) with a p value<7.05, but a singificiant time sequential intracuff pressure difference was not observed between the two groups.

A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.
