Objectives : The purpose of this study is to evaluate the usefulness of SSEP monitoring during intracranial aneurysm surgery and compare the characteristics of wave change in relation to neurologic changes between ACA aneurysms and MCA aneurysms. Methods : During recent three years(between January 1997 and November 1999), intraoperative SSEP monitoring had been done in 63 operations for intracranial aneurysms. We had monitored the median nerve SSEP during surgery for aneurysms of MCA and the posterior tibial nerve SSEP for aneurysms of ACoA or ACA. A more than 50% reduction of any cortical SEP response was considered to be a significant SEP change, compared to its baseline value before the start of surgery. Changes in the SEPs were categorized as follows : Type IA, no significant amplitude changes without temporary clipping ; Type IB, no significant amplitude changes with temporary clipping ; Type II, significant changes with temporary clipping and complete return to control amplitude ; Type III, significant changes with temporary clipping and incomplete return to control amplitude ; Type IV, significant changes with temporary clipping and more decreased amplitude changes. Results : Among the 63 intraoperative monitoring, there were 37 cases of ACA aneurysms(An), and 26 of MCA An. The temporary proximal arterial occlusion during surgery were performed in 31(83.8%)cases of ACA An, 22(84.6%) of MCA An. Seven of the 31 ACA An(22.6%) and ten of the 22 MCA An(45.5%) had significant changes. The type were as follows : 4 patients with type II and 3 with type III in the ACA An ; 3 patients with type II and 3 with type III and 4 with type IV in the MCA An. In both group type II changes had no new postoperative neurological deficit. All 6 patients with type III had new neurological deficits ; However, One case in the ACA An and two cases in the MCA An. had transient neurologic deficit and improved markedly over the next two months. All 4 type IV changes in the MCA An. had permanant neurologic deficits. Two out of 30 cases(6.7%) in the ACA An. and one out of 16 cases(6.3%) in the MCA An. without significant amplitude change had new neurologic deficit postoperatively. Conclusion : Based on this study, Intraoperative SSEP monitoring during aneurysm surgery would provide useful information for detecting cerebral ischemia. SSEP response during surgery for MCA An. is more sensitive than ACA An. Otherwise, there were no meaningful difference in rate of false negativity.

A 4-month-old female patient admitted because of hydrocephalus. She was premature infant with germinal matrix hemorrhage at gestational period 27 wks. A ventriculoperitoneal shunt with a low-pressure type valve was placed. Follow-up CT scan obtained 3 months after VP shunt placement, revealed a new Lt. middle cranial fossa cyst. The girl was readmitted to hospital at 7 months after VP shunt placement, complaining of lethargy and vomiting. A CT scan was demonstrated a increase in size of a cyst, She subsequently underwent a left-sided pterional craniotomy with partial excision of membrane and cyst fenestration into the basal cisterns. Follow-up CT scan after 18 months revealed reaccumulation of cyst, the girl was reoperated on. After 2 months, the size of cyst was not decreased. Finally, She underwent a cystoperitoneal shunt. Follow-up CT scan after 5 months was demonstrated disappeared cyst and reexpansion of brain parenchyma. We report the development of a symptomatic sylvian fissure arachnoid cyst developed after ventriculoperitoneal shunt.

Antenatal diagnosis for IUGR is very important to obstetrcians and pediatricians because it usually influences to high perinatal mortality and long-term morbidity after birth. For the diagnosis and prevention, it is valuable to know the obstetrical characteristics of IUGR. 1. the incidence of IUGR was 9.3% of total deliveries. 2. 46% of the obstetric patients in the IUGR group demonstrated no evidence of obstetric, gestational and maternal-medical complications but 54% of the patients had one or more complications. 15% of the IUGR mother with complications(54%) had obstetric complications such as toxemia and antepartum hemorrhage, 19% had gestational complications such as twin pregnancy, congenital anomaly and post date pregnancy 14% had gestational complications in the previous pregnancy, and the remainder 6% had medical complications such as chronic hypertension and chronic renal disease. 3. An increased risk of IUGR was probably evident in the patients of severe preeclampsia chronic hypertension, chronic renal disease and twin pregnancy. And to a less degree it was also evident in patient with a history of low birth weight infant in previous pregnancy, congenital anomaly antepartum hemorrhage, mild toxemia nad post date pregnancy.

Hou Hsiao hsien is a leader of "New Cinema" pursuing contemplative media aesthetics as continuously making films of native tendency examining the history of Taiwan and Mainland China, and at the same time a movie director who was greatly affecting on Taiwan motion pictures. This study is for specific examination and analysis on "frame within frame", that is, "second cadre" expressed in the movie by Hou Hsiao hsien. The researcher selected 〈A City Of Sadness〉(1989), 〈Cafe Lumiere〉(2003), and 〈Three Times〉(2005). As the results of reviewing these three movies, it can be known that the second cadre is an effective technique visually emphasizing movie characters and concentrating on mentalities of those characters at the same time. Also, it could be known that the implication of descriptive content or subject and the facts of continuous and repeated events (subject) with the third cadre method took a role of reminding more the story which was structurally repeated. Besides, it could be known that as expressing in combination of the second cadre and perspective, there is a case of creating newer meaning.

With the open the door policy for Japanese pop culture, it has been over 10 years since Japanese movies were officially imported. Starting with “Hana-bi” directed by Kitano Takeshi, The Eel(1997), The shadow warrior(1980), Narayama Bushiko(1982) were sequentially released. Although film audiences had been curious about the Japanese movies long before officially seeing Japanese movies in a movie theater, those movies did not satisfy the audiences’ expectation. Love letter directed by Iwai Shuunji in 1999 dramatically reversed the situation. Love Letter even created a fever of the director Iwai Shuunji. Japanese critics criticized that as Iwai Shuunji was possessed with visualization and focused on the minute detail without the main theme, he just sophisticated the expression and failed facing the reality as it was. However, the young audience response did the opposite and enthusiastically welcomed his contemporary air and sentiment. Therefore, this study demonstrates how Iwai Shuunji uses the Rule a third and a balance through comparing Love Letter (1999) with April Story(2003) and intensively analyzes both of them. This study also reveals how the emotion can be effectively conveyed between movie audience and the mise-en-scene he creates.

Tumoral calcinosis is rarely encountered disease, and most of reported cases involved large joints such as hip or elbow. We report two patients with tumoral calcinosis in the foot. In the 1st case, the lesion was observed at the 1st MP joint of foot, and in the 2nd case it was found at the DIP joint of 5th toe area with bony erosion which is rare in other tumoral calcinosis. They all needed evaluation with MRI, and eventually surgical excision.

A sixteen years old male patient was treated with the fractionated stereotactic radiosurgery(FSR) using Novalis system. The patient had surgery initially at other hospital before FSR and suffered from visual and endocrine dysfunctions which was required hormone replacement. Seven months after FRS, we found marked decrease of tumor volume. Now he is followed for 1 year. There is a still controversy regarding the ideal management of craniopharyngiomas. Radical resection is hazardous and can produce unacceptable mortality and morbidity. Many authors noted that postoperative conventional radiotherapy or Gamma knife radiosurgery after limited excision achieved better results than total excision of tumor for survival and postoperative complications. FRS delivered precise radiation to a target volume in close proximity to surrounding critical structures resulted in tumor regression. FRS using the relocatable mask frame may have a good role for adjuvant treatment of recurred or relapsed craniopharyngiomas.

저자들은 최근 비교적 드문 것으로 알려져 있는 난소 피양낭종의 서로 다른 형태의 파열 3 예를 경험하였기에 간략한 문헌고찰과 아울러 증례를 보고하였다. Rupture of benign cystic teratoma is a rare and interesting gynecologic entity, to be divided into two main groups of intraperitoneal rupture and rupture into hollow viscus. Many explantaton have been advanced to explain rupture of these tumors, among which torsion with infarction and gangrene, trauma, infection and malignant degeneration are considered prominent. Many cases still remain unexplained and other factors such as prolonged pressure as would occur in labor, and idiopathic causes must be considered important. Here three cases of dermoid cyst rupture including spontaneous intrapertoneal rupture due to malignant degeneration and rupture into bladder have been presented with a brief of literature.

정상 비임신부 20명, 임신 전반기 임신부 32명, 포상기태 환자 7명, 융모상피암 환자 10명을 방사면역 측정법을 이용하여 Alpha-fetoprotein(AFP) 값을 측정하여 다음과 같은 성적을 얻었다. 1. 정상 비임신부의 혈청 AFP값은 0-15ng/ml이고 평균값은 6.0ng/ml이며 이들 혈청 AFP값은 연령, 임신회수 및 출산회수와는 관계가 없었다. 2. 전반기 임신부의 혈청 AFP값은 임신 12주부터 정상 비임신부 보다 높은 값을 나타냈고 임신주수가 증가함에 따라 AFP값도 점점 상승하였다. 3. 포상기태 환자에서 배출 수술전과 수술후의 혈청 AFP값은 대체로 정상 비임신부 혈청 AFP값 이하이었으며 환자의 연령, 임신회수, 무월경 주수와는 관계가 없었다. 4. 융모상피암 환자에서 화학요법만의 단독치료 또는 수술 및 화학요법의 복합치료 전과 후의 혈청 AFP값은 정상 비임신부 혈청 AFP값 범위내에 있었다. Serum alpha-fetoprotein levels were measured by radioimmunoassay in 20 cases of normal nonpregnant woman, 32 cases of early pregnancy, 7 cases of hydatidiform mole and 10 cases of choriocarcinoma from October, 1976 to July, 1977 in the Department of Obstetrics and Gynecology of St. Mary`s Hospital, Catholic Medical College. 1. Serum alpha-fetopretein(AFP) levels in normal nonpregnant women were in a range of 0 to 15ng/ml. 2. During early pregnancy maternal serum AFP levels begin tobe increased gradually from 12th week of pregnancy, and its regression equation according to week of pregnancy were as follow: Y=20.4X-228.0(r=0.975, p<0.01, Y=value of serum AFP, X=week of pregnancy) 3. Serum AFP levels were measured below its value of normal nonpregnant women in six of seven patients with hydatidiform mole. 4. Serum AFP levels were not different from normal non-pregnant women in 10 patients with choriocarcinoma. It showed no remarkable change after chemotherapy and surgical managment.
