The mesenchymal chondrosarcoma of the orbit is so rare that only a few cases have been reported in Korea and world-wide. We experienced that a patient whose complaints were proptosis and diplopia caused by orbital tumor. After tumor removal, it was histologically diagnosed as mesenchymal chondrosarcoma. So we report a case of mesenchymal chonrosarcoma of the orbit with a review of the literature.

OBJECTIVE: The exact position of the lesion during the pallidotomy is critical to obtain the clinical improvement of parkinson's disease without damage to surrounding structure. Ventriculogrphy, CT(computed tomograpy) or MRI(magnetic resonance imaging) have been used to determine the initial coordinates of stereotactic target for pallidotomy. The goal of this study was to determine whether microelectrode recording significantly improves the neurophysiologic localization of the target obtained from MRI. METHODS: Twenty patients were studied. They underwent a unilateral pallidotomy. Leksell frame was applied and T1 axial images parallel to the AC-PC(anterior commissure-posterior commissure) plane using a 1.5 Tesla MRI with 3mm slice thickness were obtained. Anteroposterior coordinate of target was chosen at 2mm in front of the midcommissural point and lateral coordinate between 19 and 22mm from the midline. The vertical coordinate was calculated on coronal slice using a fast spin echo inversion recovery sequence(FSEIR) related to the position of the choroidal fissure and ranged over 4-5mm below the AC-PC plane. Confirmation of the anatomical target was done on axial slices using the same FSEIR sequence. Microrecording was done at the pallidum contralateral to the symptomatic side using an electrode with a tip diameter of 1nm diameter tip and 1.1-1.4 mOhm impedance at 1000Hz. Electrophysiologic localization of the target was also confirmed intraoperatively by macrostimulation. RESULTS: Microrecording techniques were reliable to define the transition from the base of the pallidum which was characterized by the disappearance of spike activity and by the change of the audible background activity. Signals from high amplitude neurons firing at 200-400Hz were recorded in the pallidal base. X, Y and Z coordinates of target obtained from the MRI were within 1mm from the X, Y, Z coordinates obtained with microrecording in 16 patients (80%), 15 patients(75%), 10 patients(50%) respectively. The difference of Y coordinate between on MRI and on microrecording was 4mm in only one patient. CONCLUSION: The MRI was accurate to localize the target within 1mm of the error from microrecording target in 70% of the patients. 4mm discrepancy was observed only once. We conclude that MRI alone can be used to determine the target for pallidotomy in most patients. However, microrecording technique can still be extremely valuable in patents with aberrant anatomy or unusual MRI coordinates. We also consider physiologic confirmation of the target using macrostimulation to be mandatory in all cases.

Aggressive angiomyxoma is a rare, locally infiltrative soft tissue tumor that usually arises in the vulvoperitoneal region of young female. Frequent relapses are common. Clinicians should consider the diagnosis of aggressive angiomyxoma when a patient presents with an atypical vulvoperineal mass, because an incorrect diagnosis may lead to repeated surgical procedures. Treatment is wide surgical excision. Medical management with a GnRH agonist and radiation therapy with total dose of 60 Gy may be helpful adjuvant treatment in recurrent aggressive angiomyxoma. We experienced a case of recurrent aggressive angiomyxoma and report it with a brief review of literatures.

OBJECTIVES: This study was performed to evaluate the relationships between psychosocial characteristics and changes in the stage of breast cancer screening behavior. METHODS: The 474 study subjects were randomly sampled from 21,459 women (age range, 40-70 years) who were eligible for the Korean National Cancer Screening Program in 2006 in Jinju, Gyeongsangnam-do. The information, including behaviors and sociodemographic characteristics, attitudes, subjective norms and self-efficacy, was collected by trained interviewers via home visits. The breast cancer screening stages were grouped as precontemplation, contemplation, action, maintenance and relapse, according to Rakowski. RESULTS: Of the 474 women, 18.8% were in the precontemplation stage, 23.3% were in the contemplation stage, 13.1% were in the action stage, 36.6% were in the maintenance stage, and 8.2% were in the relapse stage. The distribution of stages was associated with attitude, subjective norms and self-efficacy (p for trend<0.01). To investigate the overall relationship between the variables, we conducted a linear structural equation model analysis based on the theory of planned behavior. The subjective norms and self-efficacy influenced the stage of the women's screening behavior. CONCLUSIONS: We should target on self-efficacy about the screening behavior of women by performing timely, thoughtful interventions. The support from family members, friends and other people is crucial for women to undergo breast cancer screening and to improve the breast cancer screening rate.

Congenital glioblastoma multiforme is relatively rare accounting for 2-9% of all congenital brain tumors. We deseribe a case of congenital glioblastoma multiforme which occurred in the lateral ventricle. T1-weighted images revealed high signal intensity, with areas of internal low signal intensity, while T2-weighted images showed low signal intensity with focal internal high-signal portions. Post-contrast T1-weighted images depicted a lateral ventricular mass which extended to adjacent brain parenchyme and had a serpentine signal void representing internal vessel.

Hydatidiform moles are generally separated into two classifications. Complete hydatidiform moles are characterized by cystic swelling of all villi, often pronounced trophoblastic hyperplasia, lack of fetal parts, all 46 chromosomes of paternal origin, and a major risk for persistent trophoblastic tumor. Partial hydatidiform moles appear to be a milder version of complete moles with both normal and cystic villi, focal trophoblastic hyperplsia, a fetus or indication of previous fetal existence, 69 chromosomes with a maternal contribution, and a malignant potential less than described for complete moles. Hydatidiform mole with coexistent fetus is a very rare phenomenon, with an estimated incidence of 0.005 to 0.01 percent of all pregnancies. Due to advances in cytogenetics and ultrasonography, now permit the diagnosis of this pregnancy antenatally. However this unusual pregnancy has the risks of malignant change and severe medical complications, so it is a dilemma to decide continuation or termination of pregnancy. We experienced a case of partial hydatidiform mole with coexistent live fetus, which was diagnosed by ultrasonography at 12 gestational weeks, and confirmed normal karyotype (diploid) of the coexistent fetus. A brief reviews of related literature was done.

Congenital cystic adenomatoid malformation of the lung (CCAM) is a rare benign pulmonary lesion characterized by abnormal overgrowth of the fetal bronchiole. The prenatal diagnosis of CCAM is important because the prognosis of the CCAM is depend on the type, bilaterality, and other associated abnormalities, which can be detected by prenatal ultrasonography. We experienced a case of CCAM that was detected by prenatal ultrasonography and report the case with a review of several related literatures.

To study the effect of extracranial-intracranial(EC/IC) bypass on symptomatic patients with hemodynamic cerebral ischemia, we prospectively reviewed 14 patients who underwent EC/IC bypass surgery. A series of 14 patients treated in a 2 years period met the following criteria, 1) symptomatic internal carotid artery(ICA) or middle cerebral aetery(MCA) obstruction or stenosis over 80M, 2) decrease in basal cerebral blood flow(CBF) over 10%, 3) hyporeactivity to acetazolimide of CBF Amomg these, the type of ischemic episode was transient ischemic attack(TIA) or reversible ischemic neurological deficit(RIND) in 4, minor stroke in 8, and major stroke in 2. Of these, 10 patients had multiple episode of ischemic attack. CT or MRI were showed infarction of the MCA territory in 3, border zone infarction in 5, basal ganglia infarction in 2 and multiple lacunar infarction in 4. Based on our criteria, superficial temporal artery(STA)-MCA anastomosis was performed in 13 cases and EC-IC bypass grafting using radial artery in one. Average follow up period was 24 months. Postoperative course was uneventful in 12 patients. One patient suffered a postoperative stroke with complete recovery and another suffered operative wound infection. Of the 14 patients 12(85.7 % ) have had an excellent to good outcome with complete resolution or significant improvement of preoperative neurologic symptom, remaining two show no improvement of preoperative neurologic deficit. Bypass patency was confirmed by postoperative angiography in all cases except for one. Postoperative follow up studies of the basal CBF and response to the acetazolamide of the CBF showed significant increased CBF activity to acetazolamide in 12 cases(85. 7%) while the basal CBF was essentially unchanged in all cases except for two. In view of these finding, the authors suggest that EC-IC bypass surgery to be considered as an appropritate therapy for improvement of the cerebrovascular reserve capacity in patients with hemodynamic cerebral ischemia, defined using the strict selection criteria employed in this study.

OBJECTIVES: The purpose of this preliminary study was to investigate job stress and stress coping strategy among workers in a regional statistics office. METHODS: A total of 133 workers in regional statistics office participated in this study and they were divided into two groups, survey group(n=109) and support group(n=24) depending on relation to statistical survey task. They were asked to respond to Short Form of Korean Occupational Stress Scale(KOSS-SF) and Stress Coping Strategy(SCS) to investigate sociodemographic characteristics, job stress, and stress coping strategy. RESULTS: The proportion of the 133 participants in the sample was 59(44.4%) of men, 74(55.6%) of women. There were no significant differences in KOSS-SF scores in relation to age, sex, education, and marital status, while the KOSS-SF scores were significantly different between the two groups. In regard to the subscales of KOSS-SF, the two groups had significant differences in insufficient job control, interpersonal conflict, job insecurity, and organization system. In addition, the total score of KOSS-SF had a negative correlation with problem-focused coping strategy and social support coping strategy of SCS. CONCLUSIONS: Our results suggest that workers of survey group had more job stress compared to those who works in support group in regional statistical office. In addition, in comparison with workers of support group, both men and women of survey group get stressed when they were confronted with interpersonal conflicts. Our results suggest that using problem-focused coping and social support coping strategy lowers job stress.

Peutz-Jeghers syndrome is a rare autosomal dominant disorder defined by harmatomatous polyps of the gastrointestinal tracts and the occurrence of melanin spots on the lips(oral mucosa), hands and feet. This syndrome is associated with a variety of gastrointestinal and extraintestinal neoplasms, both benign and malignant. A 28-year old male was admitted to our hospital with abdominal pain and nausea for two months. He had melanin spots involving his lips, buccal mucosa, hands and feet. A small bowel series showed luminal obstruction at the forth portion of the duodenum. And abdominal CT scan showed target-like mass suggesting intussusception on the small bowel. On laparotomy, there was an annular constricting mass adherent to retroperitoneum with metastasis to preaortic lymph nodes. Palliative duodeno-jejunostomy was performed. The histologic finding disclosed signet-ring cell type adenocarcinoma.
