Malignant germ cell tumore occur in children and young women in reproductive age, of all the germ cell maligaanci orily pure dysgerminiomas had a high cure rate prior to 1970. This was due to the exquisite wdioseneitivity of these tumors. Multiple agent chemotherapy has dramatieally improved the pr nosis af patients with malignant ovarian germ cell tumors. The purpose of this study is to report the experience at Aaan Medical Center, department of Obstetrics and Gynecology, in 16 patients withmalignant ovarian germ cell tumors treated between July, l989 and June, l994. We analyzed the effect of age, histolagic subtype, FIGO stage, surgical pmcedurse and regimens of chemotherapy, on the prognosis of thwe tumors. The results obtained were as follows: 1. In histologic subtypes, dysgenninoma(38.0%), endodermal sinus tumor(25.0%), squamous cell carcinoma arising in mature cystic teratoma(19.0%), mixed cell tumor(6.0%), immature teratoma(6.0%), malignant ectodermal tumor in mature cystic teratoma(6.0%), were counted in order. 2. No site predilection was identifed. 3. Main initial symptoms were abdominal distension(31.0%), abdominal pain(31.0%), abdominal mass palpation(25.0%), amenorrhea(6.0%) in order. 4. Multiple tumor markers were considered to be useful in diagnosis and follow up of malignant germ cell tumors of ovary. 5. The mean age of malignant ovarian germ cell tumors was 29.5 years, and 11 cases(69.3%) of tumors under the age of 30.0 years. 6. The survival rate seemed to be decreased with advancing FIGO stage.

OBJECTIVE: Meige syndrome is the combination of blepharospasm and oromandibular dystonia. We assessed the surgical results of bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) in patients with medically refractory Meige syndrome. METHODS: Eleven patients were retrospectively analyzed with follow-ups of more than 12 months. The mean follow-up period was 23.1 +/- 6.4 months. The mean age at time of surgery was 58.0 +/- 7.8 years. The mean duration of symptoms was 8.7 +/- 7.6 years. DBS electrodes were placed under local anesthesia using microelectrode recording and stimulation. After 2.4 +/- 1.3 days of trial tests, the stimulation device was implanted under general anesthesia. Patients were evaluated using the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS). RESULTS: BFMDRS total movement scores improved by 59.8%, 63.5%, 74.1%, 74.5%, and 85.5% during the immediate postoperative period of test stimulation, 3, 6, 12, and 24 months (n = 5) after surgery, respectively. The BFMDRS total movement scores were reduced gradually and the results reached statistical significance in the postoperative period (test period, p < 0.001; 3 months, p < 0.001; 6 months, p = 0.003; 12 months, p < 0.001; 24 months, p = 0.042). There was no statistical difference between 12 months and 24 months. BFM subscores improved by 63.3% for the eyes, 80.9% for the mouth, 68.4% for speech/swallowing, and 87.9% for the neck at 12 months after surgery. The adverse effects were insignificant. CONCLUSION: The bilateral GPi-DBS can be effective for the treatment of intractable Meige syndrome without significant side effects.

To investigate the change in upper eyelid position after cataract operation, We studied 40 eyes of 40 patients prospectively who underwent phacoemulsification and intraocular lens implantation. Levator function and vertical palpebral lid fissure height were measured preoperatively and at postoperative day 1, 7, 28 and 56 in and the surgical and the fellow eyes. Postoperative mean vertical lid fissure height decreased compared with preoperative mean vertical lid fissure height in both eyes. The postoperative decrease in vertical lid fissure height tended to decrease with times and these trends had statistically significant correlation between both eyes. This suggests that both eyes are affected by factors unassociated with the cataract surgery and it is most apparent in the immediate postoperative period. In conclusion, we recommend not only the surgical eye but the fellow eye should be evaluated preoperatively and postoperatively to understand the eyelid position after cataract operation.

OBJECTIVES: The aim of this study was to investigate mortality rates and risk factors in dementia patients in a rural cohort. METHODS: A total of 114 subjects with clinically diagnosed dementia were followed up for eight years from 1997 to 2005. Their mortality was compared with sociodemographic and clinical variables using the Cox proportional hazards models after adjusting age, sex, and education. RESULTS: During follow-up, the mortality rate of subjects was 80.2% and the mean (SD) duration of survival from at diagnosis to death was 4 years. Mortality in subjects with dementia depended on old age (relative risk [RR] : 1.05 ; 95% confidence interval [CI] : 1.01-1.08), male (RR : 1.61 ; CI : 1.00-2.59), low Clinical Dementia Rating scale (RR : 1.54 ; CI : 1.14-2.10), low Activities of Daily Living (RR : 0.72 ; CI : 0.59-0.89), low Instrumental Activities of Daily Living (RR : 0.83 ; CI : 0.75-0.92), no physical activity (RR : 0.44 ; CI : 0.28-0.70), smoking (RR : 1.74 ; CI : 1.05-2.89). CONCLUSION: Mortality in dementia depended on age, sex, CDR, ADL, IADL, physical activity, smoking. These findings have important implications that contribute to make the disease management of dementia patients.

Inadequate pain management after total knee arthroplasty (TKA) impedes recovery, increases the risk of postoperative complications, and results in patient dissatisfaction. Although the preemptive use of multimodal measures is currently considered the principle of pain management after TKA, no gold standard pain management protocol has been established. Peripheral nerve blocks have been used as part of a contemporary multimodal approach to pain control after TKA. Femoral nerve block (FNB) has excellent postoperative analgesia and is now a commonly used analgesic modality for TKA pain control. However, FNB leads to quadriceps muscle weakness, which impairs early mobilization and increases the risk of postoperative falls. In this context, emerging evidence suggests that adductor canal block (ACB) facilitates postoperative rehabilitation compared with FNB because it primarily provides a sensory nerve block with sparing of quadriceps strength. However, whether ACB is more appropriate for contemporary pain management after TKA remains controversial. The objective of this study was to review and summarize recent studies regarding practical issues for ACB and comparisons of analgesic efficacy and functional recovery between ACB and FNB in patients who have undergone TKA.

OBJECTIVE: Strategies for managing supratentorial primitive neuroectodermal tumors(PNETs) in children include surgical resection, craniospinal irradiation and chemotherapy. This study is performed in order to compare the efficacy of various methods of treatment and to describe its optimal management. METHODS: We have reviewed all medical records and pathology slides of six children(four males and two females) with supratentorial PNET from November, 1987 to May, 2003. The extent of resection was confirmed by computed tomography and magnetic resonance studies. RESULTS: The patients were aged 1 to 13 years and treated postoperatively with/without adjuvant therapy. Tumor location included was four cortical, one gangliobasal, and one pineal region. The presenting symptoms and signs consisted of increased intracranial pressure and focal neurological deficits such as seizure and hemiparesis. The treatment consisted of surgical resection alone in one patient, postoperative radiotherapy in one patient, postoperative chemotherapy in one, and postoperative radiotherapy with chemotherapy in three. Five patients lived more than 12 months after diagnosis and one patient among them has been living more than 5 years after diagnosis. CONCLUSION: We can improve the survival and prognosis of supratentorial PNET patients by radical gross total resection of tumor followed by craniospinal irradiation and aggressive chemotherapy. First of all, gross total resection of tumor is the most important among many factors.

BACKGROUND: Septic shock is characterized by an abnormal vascular tone that has been related to various factors. Myocardial depression can also occur in septic shock. Various experimental studies have indicated that the myocardial depression could be present early in the course of septic shock. This study aimed to assess hemodynamic characteristics according to outcome of septic shock in emergency department. METHOD: The study population comprised 20 patients admitted to our emergency department for septic shock. All patients with septic shock(prolonged hypotension, signs of tissue hypoperfusion, signs of sepsis, suspected source of infection, or documented bacteremia) had conventional serial hemodynamic evaluations in emergency department to identify early hemodynamic variables that predicted outcome. All patients were monitored with a pulmonary artery catheter and an arterial catheter. Hemodynamic measurements and oxygen profile were obtained. RESULTS: There were 9(53%) survivors and 8(47%) nonsurvivors. There were no significant differences in systolic pressure, pulse rate, mean pulmonary artery pressure, pulmonary capillary wedge pressure, systemic vascular resistance index, and pulmonary vascular resistance index between survivors and nonsurvivors at initial hemodynamic value. However, significant differences were found in cardiac index(4.3+/-0.5 vs. 2.74+/-0.7 L/min/m2), stroke volume index(44+/-10 vs. 23+/-5 ml/beat/m2), left ventricular stroke work index(39+/-11 vs. 15+/-6 gm m/m2), and right ventricular stroke work index(8.1+/-3.0 vs. 5.2+/-2.9 gm m/m2) between survivors and nonsurvivors at initial hemodynamic value. CONCLUSION: Survivors had better myocardial function than nonsurvivors during the early phase of septic shock. This results suggest that myocardial depression during septic shock develops in the early course of septic shock, which is associated with outcome.

This study was undertaken to determine the prevalence and the natural course of venous thromboembolism (VTE) without thromboprophylaxis to ascertain whether routine thromboprophylaxis is necessary following unicompartmental knee arthroplasty (UKA) in Korean patients. The medical records and multidetector row computed tomography (MDCT) imaging of the consecutive 77 UKAs in 70 patients were reviewed. In all patients, MDCTs were undertaken preoperatively and at 1-week after surgery, and VTE symptoms were evaluated. At postoperative 6-months, follow-up MDCTs were undertaken in all patients in whom VTEs were newly detected after surgery. VTE lesions were newly detected in 18 (26%) of the 70 patients. However, none of the patients complained of VTE-related symptoms and MDCT demonstrated that all VTEs were small and involved limited portion without lower leg edema or pleuroparenchymal complication. At the 6-month follow up MDCT, all types of VTEs were shown to be completely resolved, regardless of their location. All of the VTE lesions maintained an asymptomatic status for 6-month after surgery. VTE following UKA in Korean patients who do not receive thromboprophylaxis seems to occur frequently, but all of the VTEs are clinically insignificant and all VTEs are spontaneously regressed. Routine thromboprophylaxis or thrombolytic treatment in Korean patients undergoing UKA may not be necessary.
