In the treatment of elderly hip fracture, early mobilization as a means of reducing early postoperative morbiyt and morbidity is mandatory. Even though Ender nailing have many advantages, most serious problems with use of Ender nailing method are distal migration of nails, subsequent loss of fixation and limited knee joint motion. To prevent these difficult problems, we have used distal wiring technique with Ender nailing since 1988. In operation, we performed Ender nailing as usual manner under image intensifier and for the prevention of the nail migration, we performed circumferential wiring through the each Ender nail eye and above the adducter tubercle of the distal femur. Forty six cases were available with minimum follow-up of six months which were healed radiologically and clinically (Mean follow up: 21 months). The mean age was 74 years (Range: 52 years-88 years)and showed 26 cases of famale and 20 cases of male. The radiological morphometry using Singh index showed poor bone quality: 36 cases were below Grade III and the fracture type was classified by Tronzo criteria. In results, patients who had Ender nailing with distal wiring showed no distal migration, however one case of proximal migration was observed at the beginning stage of this technique. So, in elderly trochanteric fracture, to reduce the complication of the Ender nailing, especially nail migration, the authors recommend the Ender Nailing with distal wiring technique.

Acromioclavicular joint injuries are recently increased, but there are still controversies as to the proper choice of treatment. We treated thirty cases of acromioclavicular injuries, among these, twenty five cases were done by operative method and five cases conservatively from August 1979 to June 1988. The results were as follows, 1. The injuries were composed of one case of Type 1, 7 cases of Type 2 and 22 cases of Type 3. 2. The result of conservative treatment consisted of 2 cases of good, 1 case of fair and 2 cases of poor. 3. The final outcome of operative method was better than that of conservative one, which consisted of 16 cases of good and 9 cases of fair. 4. The cause of fair results in operative method was thought to residual lexity of the repaired coracoclavicular ligament. 5. The key point of operative treatment in acromioclavicular separation was firm and strong reconstruction of the coracoclavicular ligament. 6. Modified method of coracoclavicular ligament reconstruction using coracoacromial ligament with bone block has been tried.

BACKGROUND: We examined the ability of thiopental known to have protective effect on brain to prevent brain damage resulting from cerebral ischemia due to global imbalance in cerebral metabolic rate for oxygen and cerebral blood flow during rewarming period in cardiopulmonary bypass. METHODS: Jugular venous oxygen saturation(SjO2) was used as a reflection of cerebral oxygen balance. Thiopental 20 mg/kg(thiopental 10 mg/kg bolus and 10 mg/kg continuous infusion) was received during rewarming from hypothermic cardiopulmonary bypass of 27~30.5degrees C to 36degrees C and SjO2 compared with control group. RESULTS: In 8 patients of the 25 control group(32%) and 7 patients of the 24 thiopental group(29.2%), SjO2 were < or =50% with no difference between groups. Artery-jugular vein oxygen content differences (C(a-j)O2) and O2 extraction ratios increased significantly in SjO2 < or =50% patients suggesting increased oxygen consumption. Awake time prolonged significantly with thiopental. CONCLUSIONS: Thiopental(20 mg/kg) administration during rewarming in cardiopulmonary bypass for cerebral protection is not recommended.

Protamine sulfate, a strong polycationic polypeptide, combined with acidic heparin to form a neutral salt, eliminates the anticoagulating properties of heparin. Heparin reversal with protamine after cardiopulmonary bypass may complicate with adverse hemodynamic effects including systemic hypotension, decreased cardiac output, changes in systemic and pulmonary vascular resistances, anaphylaxis and noncardiogenic pulmonary edema. We recently observed a case of severe pulmonary vasoconstriction with right ventricular failure after protamine administration in 37-year-old woman with mitral stenosis who underwent mitral valvuloplasty. After uneventful termination of cardiopulmonary bypass, administration of protamine was associated with sudden elevation of pulmonary arterial pressure with profound right ventricular distension and systemic hypotension by which heparin-protamine reaction is suspected. After intravenous epinephrine infusion and cardiac massage, these changes were reversed. Although the mechanism of this protamine-heparin induced response is unclear, complement activation and thromboxane release may play a role in the development of pulmonary vasoconstriction.

Cardiac output depends on the ability of systolic ejection and diastolic filling of the heart. M-mode echocardiography can provide accurate clinical assessment of left ventricular systolic and diastolic functions. To see whether there are changes of the left ventricular function in asymptomatic hypertensives and if any kind of dysfunction and whether any relationship between the pattern of the ventricular hypertrophy and type of ventricular dysfunction exists, the authors examined the systolic and diastolic function indices of the left ventricle in 50 normotensives and 88 hypertensives composed of 18 patients without left ventricular hypertrophy(group 1), 40 patients with disproportionate septal thickening (group 2) and 30 patients with concentric left ventricular hypertrophy(group 3). Obtained results were as follows : 1) Blood pressure & left ventricular mass index were increased significantly in each hypertensive group compared to normal control. 2) Ejection fraction & fractional shortening in the hypertensive groups were not different from the normotensive control group. 3) Left ventricular isovolumic relaxation time(A2D time) was prolonged in each hypertensive group, especially in group 3. 4) Left atrial emptying index (AEI) was decreased in each hypertensive group. 5) Left ventricular percent ventricular A wave (% VAW) was increased in all hypertensive groups. Above study suggested that the left ventricular diastolic function could be impaired in the hypertensives without associated systolic dysfunction, and the degree of the diastolic dysfunction was not much affected by the type of left ventricular hypertrophy, but the more prolonged A2D time in the concentric hypertrophy group.

Two factors of the ventricular function, systolic contractile and diastolic relaxing functions, cooporate in pumping the adequate blood volumes to suffice bodily demands. In some hypertensive patients with marked left ventricular hypertrophy, the intact systolic function of the ventricle associated with clinical symptom of congestive heart failure(CHF), which is considered to be a consequence of diastolic dysfunction. In this study 10 hypertensive patients(group A) complaining of exertional dyspnea or chest pain with increased left ventricular mass index and normal systolic function and 6 normotensive controls(group B) were examined by cardiac catheterization and echocardiography to assess the left ventricular systolic and diastolic function and ventricular responses to constant infusion of nitroprusside. Various systolic and diastolic function indices were measured by cardiac catheterization and echocardiography. 1) The ejection fraction(EF), fractional fiber shortening, mean velocity of circumferential fiber shortening, left ventricular(LV) peak+dp/dt, change of slope of LV peak systolic pressure-volume and pressure-dimension relations in group A were not different from those of group B in the resting states. 2) Diastolic dysfunction was evidenced by prolonged A2D time, decreased OR slope, decreased peak negative dp/dt and increased diastolic time constant 'T' in group A. 3) Cardiac index by thermodilution method was negatively related to left ventricular mass index(LVMI) measured by echocardiography, whereas time constant T was positively related to LVMI. 4) With constant infusion of nitroprusside, LV systolic pressure, LV end-diastolic pressure and pulmonary arterial pressure were decreased, and left ventricular end-systolic stress and stroke work index(SWI) derived from left ventricular pressure-volume loop area were decreased, EF was increased, but time constant T was prolonged and cardiac output(CO) by thermodilution method was decreased in group A. 5) In group B, with constant infusion of nitroprusside, EF, SWI and CO were pratically unaffected and time constant T was not prolonged significantly. These reults suggest that patients with hypertensive hypertrophic left ventricle is associated with diastolic dysfunction, which could further be exacerbated by a vasodilator such as nitroprusside.

Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techniques. The basic disciplines of approaching skull base lesions are provide direct vision, minimizing brain retraction, excellent exposure and minimal blood loss. The focus of this report is to review the advantages of skull base approach in our cases and suggest some indications. We experienced 20 cases of skull base surgery by a team approach consisting of a neurosurgeon and plastic surgeon. The surgical approach were supraorbital osteotomy(5 case), orbitozygomatic osteotomy(8 case), orbitozygomaticoglenoid osteotomy (5 case ) and orbitozygomaticoglenoidocondylar osteotomy (2 case). In our experience, these approaches provided excellent exposure of the lesion, direct access to lesions and minimal brain retraction thereby better outcome.

BACKGROUND: Hemodynamic instability is one of the main concerns for anesthesiologists during orthotopic liver transplantation (OLTX). The most troublesome event would be an increase of central venous pressure associated with sudden right ventricular (RV) filling without any change in heart contractility. An acute increase in RV outflow pressure depresses RV contractility and eventually causes overt RV failure. To avoid such disaster, it would be wise to evaluate right heart pressure/volume relationship and assess contractility when anticipating acute increase of pressure in right heart chamber. METHODS: RV function was assessed in 15 patients undergoing OLTX. RV function was monitored using an ejection fraction catheter and a monitor. Complete hemodynamic profile was obtained on regular intervals. Statistical analysis was performed using ANOVA for repeated measures. Correlation between variables were determined by simple regression analysis and ANCOVA. RESULTS: RV end-diastolic volume was in the range of supranormal values. No correlation was observed between right atrial pressure and RV end-diastolic volume index (RVEDVI). There was a significant correlation between stroke index and RVEDVI. RV ejection fraction and E-single were relatively constant throughout the procedure. There was weak negative correlation between E-signle and RVEDVI. CONCLUSION: RV function appeared to be well preserved during OLTX. However, RV contractility tends to decrease in response to RVEDV increase because RVEDV of endstage liver disease might increase to their maximal value. Right heart filling pressure was less reliable clinical indicator of RV preload.

BACKGROUNDS: As the elderly population in-creases the health problem, especially dementia, becomes the clinically important problem. So in the part of primary care medicine it becomes so important that family physician make a focus on the detection, evaluation, and management of demented patient. Until nowadays there is few cohort study about the dementia and few nursing home in Korea. So author performed the MMSE-K in the elderly who are over 65 to get the cognitive function for early diagnosis, management and rehabilitation of psychosocial problem. METHODS: One hundred three persons who included in community society in Seoul and nursing home of Kyunggido were tested. The survey was done twice on september 1997 and September 1998. Author used the MMSE-K to the elderly by same doctors. The analysis was done by SAS 6.12 and t-test, one-way ANOVA and two-way ANOVA with linear trend test. RESULTS: The mean of first MMSE-K score in the community is 26.1 and in the nursing home is 24.4. And the mean of second MMSE-K score in the community is 25.5 and in the nursing home is 22.0. The MMSE-K score is elevated with male and longer duration of education and is decreased with the advanced age in two groups. According to the classification by MMSE-K score the number of people who have normal cognitive function is 45(43.7%), mild impaired cognitive function is 45(43.7%), moderately impaired cognitive function is 13(12.6%) and none has severely impaired cognitive function in both groups. The follow up MMSE-K score shows that the difference of two MMSE-K scores increases as the age increases. CONCLUSION: Until todays there is few study that designed in the form of cohort study about the elderly cognitive function in Korea. So family physicians must perform the prospective cohort study with the consistent concern and effort to get the research data about the dementia for earthy detection, management and rehabilitation for elderly.
