The increasing use of intravenous polyethylene catheters has led to a growing incidence of accidental catheter breakage and migration of fragments into the central vascular system usually in the inferior vena cave, the right atrium, of the pulmonary artery. The most common complications were formation of a thrombus in the area of the foreign body, infection with endocarditis, and perforation of the heart. And so obviously the polyethylene catheter must be removed. In 1967, Massumi and Ross et al have been successful in removing a catheter fragment from the right atrum percutaneously with a snare device. With some modification as suggested by Curry, method of retrieving fragments of polyethylene catheters from the heart without chest surgery utilize wire snares or endoscopic forceps. This report describe the technique and its use in successfully managing these complications in four consecutive cases.

PURPOSE: The determination of tetanus prophylaxis according to patients' memories of past immunization is inaccurate. However, by using the Tetanos Quick Stick(R) test, it is possible to select Korean adults with low tetanus antibody titers and to perform tetanus prophylaxis in the emergency department. In 1996, Ha reported that tetanus toxoid injection into healthy Korean adults revealed significant differences between the tetanus antibody titers at the beginning and the tetanus antibody titers after 1 week. Our purpose is to determine the effect of a single tetanus toxoid in Korean adults with low tetanus antibody titers. METHODS: Blood samples were taken from 44 volunteers for a period of 6 weeks. All samples were analyzed using the Tetanus IgG ELISA (enzyme-linked immunosorbent assay) method. RESULTS: The results for tetanus antibody titers at the beginning and after 1 week, 2 weeks, 4 weeks, and 6 weeks were 0.04+/-0.05 IU/mL, 1.22+/-3.63 IU/mL, 4.99+/-7.3 6 IU/mL, 8.36+/-11.10 IU/mL and 6.59+/-9.21 IU/mL respectively. There was a statistically significant defference between the tetanus antibody titers at the beginning and the tetanus antibody titers after 2 weeks. There was no statistically significant defference between the tetanus antibody titers after 2 weeks and 6 weeks. After 4 weeks, all subjects' tetanus antibody titers were at the protective level. CONCLUSIONS: A single tetanus toxoid injection is effective in Korean adults with low tetanus antibody titers.

Pagonimus Westmani, occuring as an important human infestation of the lung, is widely distributed in the Far East ; Korea, Japan, China and the Philippines. Since Otani found the parasites for the first time in the human brain in 1887, it has been established that cerebral infestation occurs with the highest frequency among extrapulmonary involvement. In 0.8 to 25 percent of patients infested with the lung flukes cerebral paragonimiasis may be developed. The larvae may procedure arachnoiditis, abscess, fibrous cystic lesions and granulomas in the brain. Based on a review of the literatures and upon the 7 cases of cerebral paragonimiasis which have been observed by the authors at the National Medical Center, Seoul, Korea, the following points are stressed. 1) Males had a significantly higher prevalence than females. Cerebral paragonimiasis was most commonly found in young adults(16 to 25yrs). 2) Clinically the patients with cerebral involvement were characterized by Jacksonian type of epilepsy, headache and visual disturbance. Mental deterioration, hemiplegia, hemihypesthesia, homonymous hemianopsia and optic atrophy were the five major signs. 3) The patients having symptoms for less than 6 months developed mild leukocytosis in many cases. All the cases of cerebral paragonimiasis revealed positive reaction in the intradermal tests with purified antigens of P. Westermani. 4) On skull films multiple round or oval cystic calcification was diagnostic value for cerebral paragonimiasis. On angiogram vascular staining and abnormal vessels were not disclosed. On pneumoencephalogram subcortical atrophy or filling defect of the ventricle may be showed. 5) The predilection area of the granuloma and fibrous cystic mass were the occipital, posterior parietal and posterior temporal lobes. 6) The patients with chronic stabilized cerebral paragonimiasis. having intractable symptoms and signs, could not be improved with Bithionol treatment. But headache, vomiting, visual disturbance, facial weakness and especially intractable seizure were improved in our cases treated with surgical operation.

The authors present 2 cases of malignant pituitary adenoma. One case has remote metastases to the right frontal lobe, and the other case has invasion into the adjacent temporal lobe and malignant features histologically. Malignant pituitary adenoma constitute less than 1% of the large reported series of pituitary adenoma, which defined as (1) it burst its capsule to invade the adjacent nervous structures or bone, (2) it shows malignant features histologically, such as frequent mitoses, anaplasia with hyperchromatic pleomorphic cells, loss of alveolar arrangement, and (3) presence of distant metastases.

Objective: : Here, we evaluated whether cerebrospinal fluid (CSF) profiles and their changes after intraventricular chemotherapy for leptomeningeal carcinomatosis (LMC) could predict the treatment response or be prognostic for patient overall survival (OS) along with clinical factors. Methods: : Paired 1) pretreatment lumbar, 2) pretreatment ventricular, and 3) posttreatment ventricular samples and their CSF profiles were collected retrospectively from 148 LMC patients who received Ommaya reservoir installation and intraventricular chemotherapy. CSF profile changes were assessed by calculating the differences between posttreatment and pretreatment samples from the same ventricular compartment. CSF cell counts were further differentiated into total and other based on clinical laboratory reports. Results: : For the treatment response, a decreased CSF ‘total’ cell count tended to be associated with a ‘controlled’ increase in intracranial pressure (ICP) (p=0.059), but other profile changes were not associated with either the control of increased ICP or the cytology response. Among the pretreatment CSF profiles, lumbar protein level and ventricular cell count were significantly correlated with OS in univariable analysis, but they were not significant in multi-variable analysis. Among CSF profile changes, a decrease in ‘other’ cell count showed worse OS than ‘no change’ or increased groups (p=0.001). The cytological response was significant for OS, but the hazard ratio of partial remission was paradoxically higher than that of ‘no response’. Conclusion : A decrease in other cell count of CSF after intraventricular chemotherapy was associated with poor OS in LMC patients. We suggest that more specific CSF biomarkers of cancer cell origin are needed.

BACKGROUND AND OBJECTIVES: The Angio-Seal(r) (a St. Jude Medical Co., USA) hemostatic puncture closure device produces direct femoral arterial hemostasis, by anchoring a collagen plug to the anterior vascular wall, through a sheath delivery system. The rapid and effective hemostasis leads to earlier ambulation, minimized hospital stay, patient discomfort and vascular complications. This study was performed to evaluate the efficacy and complications of an Angio-Seal in patients undergoing coronary angiography and angioplasty. SUBJECTS AND MEHTODS: A total 228 consecutive patients, admitted to our hospital for percutaneous coronary intervention, between October 2001 and May 2002, were enrolled and randomized into 2 groups. 116 patients were treated with an Angio-Seal and the other 112 with manual compression only (control group). The clinical characteristics, procedure related factors, time to ambulation, times to outpatient discharge and complications were analyzed in each patient. All the clinical and procedure-related factors, leading to oozing and delayed bleeding, were also analyzed in the 113 patients who had a successfully completed Angio-Seal deployment. RESULTS: The times to ambulation (7.96+/-5.81 hours vs. 23.32+/-3.35 hours) and times to outpatient discharge (2.00+/-0.94 days vs. 3.47+/-3.61 days) were significantly shorter in the Angio-Seal compared to the control group (p=0.001 & p=0.001, respectively). There was oozing in 20 patients (17.7%) and delayed bleeding in 6 (5.3%) of the successful Angio-Seal deployment group. The occurrence of oozing was significantly higher in the heparin infusion cases (40%. 18.3%, p=0.034), and was correlated with a later hematoma formation rate and the size of the hematoma (30% vs. 9.7%, 0.68+/-1.26 cm vs. 0.17+/-0.70 cm, p=0.015 & p=0.001, respectively). Delayed bleeding was correlated to the hematoma occurrence rate (50% vs. 11.2%, p=0.006). CONCLUSION: The Angio-Seal resulted in earlier ambulation and shorten the patients' hospital stay. Oozing, delayed bleeding, hematomas were noted as complications. Oozing and delayed bleeding were correlated with a high hematoma occurrence rate. Careful inspection of the puncture sites, following an Angio-Seal deployment, should be performed.

We report a case of severe hypothyroidism in a cholangiocarcinoma patient with metastasis to the thyroid gland. A 58-year-old man was admitted for upper abdominal discomfort and multiple palpable neck nodules. Abdominal computed tomography (CT) demonstrated the presence of a 4.7-cm tumor in the right hepatic lobe, and core needle biopsy revealed it to be cholangiocarcinoma. Neck CT showed a diffuse, low attenuation thyroid gland, and fine-needle aspiration (FNA) demonstrated metastatic adenocarcinoma. Thyroid function tests were initially normal, but the size of the thyroid gland decreased and severe hypothyroidism developed after chemotherapy was implemented for cholangiocarcinoma. In a patient with malignant disease and a goiter, the possibility of a metastatic tumor involving the thyroid should be seriously considered. Metastatic thyroid cancer and thyroid dysfunction are probably infrequent, but diagnosis is important in the institution of appropriate therapy.

A malignant fibrous histiocytoma (MFH) is a major subset of soft tissue sarcomas, which occurs principally on the extremities or in the retroperitoneum, as well as on the head and neck of elderly patient. However, it is an extremely rare event when a MFH occurs primarily in the diaphragm of a young people. A 25-year-old woman visited our hospital complaining of right chest pain. The chest X-ray showed a diaphragmatic mass. An exploratory thoracotomic biopsy revealed a primary MFH of the diaphragm. The patient was treated with combined chemotherapy consisting of ifosfamide and doxorubicin. A partial response was seen after 6 cycles of chemotherapy. However, she died of brain metastasis 12 months after the diagnosis.

PURPOSE: For patients with Dukes' stage B and C rectal cancer, surgery followed by adjuvant chemoradiotherapy is considered to be the standard treatment. However, the drugs used in combination with 5-fluorouracil (5-FU), the method of administration, duration of adjuvant therapy and the frequencies of administration presently remain controversial topics. We investigated (1) the efficacy and safety of adjuvant radiotherapy and 5-FU/leucovorin (LV) chemotherapy for patients who had undergone curative resection and (2) the effect of dose related factors of 5-FU on survival. MATERIALS AND METHODS: 130 rectal cancer patients with Dukes' B or C stage disease who were treated with curative resection were evaluated. The adjuvant therapy consisted of two cycles of 5-FU/LV chemotherapy followed by pelvic radiotherapy with chemotherapy, and then 4~10 more cycles of the same chemotherapy regimen were delivered based on the disease stage. The cumulative dose of 5-FU per body square meter (BSA), actual dose intensity and relative dose intensity were obtained. The patients were divided into two groups according to the median value of each factor, and the patients' survival rates were compared. RESULTS: With a median follow-up duration of 52 months, the 5-year disease-free survival and overall survival rates of 130 patients were 57% and 73%, respectively. Loco- regional failure occurred in 17 (13%) of the 130 patients, and the distant failure rate was 27% (35/130). The chemotherapy related morbidity was minimal, and there was no mortality for these patients. The cumulative dose of 5-FU/ BSA had a significant effect on the 5-year overall survival for Dukes' C rectal cancer patients (p=0.03). Multivariate analysis demonstrated that only the performance status affected the 5-year overall survival (p=0.003). CONCLUSION: An adjuvant therapy of radiotherapy and 5-FU/LV chemotherapy is effective and tolerable for Dukes' B and C rectal cancer patients. A rospective, multicenter, randomized study to evaluate the effects of the cumulative dose of 5-FU/BSA on survival is required.
