A 40-year-old female patient who had tethered spinal cord with intraspinal lipoma and intractable pain of the lower leg and foot is reported. The pain started 5 years ago and exaggerated recently. A pea-size mass had been noted since birth at sacral region, which was excised 2 months prior to admission at the other clinic. Neurological examination revealed diffuse muscular wasting of the left foot, especially the sole, hypesthesia of the left sole with dysesthesia, bilaterally increased knee jerks, and absent left ankle jerk. The patient underwent L5 laminectomy, subtotal removal of extradural, intradural and intramedually lipoma with dural repair, and dorsal rhizotomy of ipsilateral L5 and S1 roots. At surgery, the neural elements were untethered with mass removal, adhesiolysis, and division of thickened arachnoid septum. The pain improved much after and was tolerable with some analgesics.

PURPOSE: This study aimed to evaluate the preliminary treatment results of fractionated stereotactic radiotherapy (FSRT) for metastatic brain tumors. MATERIALS AND METHODS: Between August 1997 and December 1998, frameless FSRT was performed in 11 patients with metastatic brain tumor (1S lesions). Primary sites were lung in 7 patients, breast in 2, stomach in 1, and malignant melanoma in 1, All patients received 30-36 Gy/10-20 fx external beam irradiation to whole brain. Eight patients received FSRT for 1 lesion, one for 2 lesions, and two for 4 lesions. Fractionation schedule was 25 Gy/5 fx in 11 lesions, 18 Gy(1 fx in 3, 30 Gy/5 fx in 2, 15 Gy/5 fx in 1. Mean tumor volume was 7.0 cc (0.39~55.23 cc). Multiple-arc FSRT was delivered to 16 lesions and conformal FSRT through irregular ports shaped to tumor profile to 2 lesions. RESULTS: No patient experienced any acute side reaction from FSRT. Follow-up radiologic evaluation was available in 9 patients. Six of nine patients achieved the complete response, but two showed the partial response and one showed no response on follow-up radiologic studies. Among six patients with complete response, 5 patients survived from 5 to 15 months and showed no evidence of metastatic brain d#isease clinically and/or radiologically at last follow-up. Among two patients who did not have radiologic evaluation, one showed clinically complete response until death and the other died just after FSRT caused by intercurrent disease. One patient with no response radiologically survived 7 months and showed nearly complete disappearance of clinical symptom with stable status radiologically, CONCLUSION: Initial experience in this study suggests that the external beam irradiation to whole brain with 30 Gy/10 fx followed by FSRT with 20~30 Gy/5~6 fx could be the good treatment option to the patients with metastatic brain tumor. This study suggests that the fractionation schedule for FSRT should be determined in consideration of performance status, number of metastasis, tumor volume, location, presence of extracranial disease, and age.

BACKGROUND: Rotational atherectomy has been shown to be safe and efficient for the treatment of ISR, but the recurrence rate is still high. Intracoronary-irradiation after rotational atherectomy may be a reasonable approach to prevent recurrent ISR. SUBJECTS & METHODS: Fifty consecutive patients with diffuse ISR (length > 10 mm) in native coronary arteries underwent rotational atherectomy and adjunctive balloon angioplasty followed by beta irradiation using a 188Re-MAG3-filled balloon catheter. The radiation dose was 15 Gy at 1.0 mm deep into vessel wall. RESULTS: Mean length of the lesion and irradiated segment was 25.6 +/- 12.7 mm and 37.6 +/- 11.2 mm, respectively. The radiation was delivered successfully to all patients, with a mean irradiation time of 201.8 61.7 seconds. No adverse event including myocardial infarction, death, or stent thrombosis occurred during the follow-up period (mean 10.3 +/- 3.7 months) and non-target vessel revascularization was needed in one patient. Six-month binary angiographic restenosis rate was 10.4 % and loss index was 0.17 +/- 0.31. CONCLUSIONS: beta irradiation using 188Re-MAG3-filled balloon following rotational atherectomy is safe and feasible for patients with diffuse ISR, and it may improve the clinical and angiographic outcomes. Further prospective randomized trials are warranted to evaluate the synergistic effect of debulking and irradiation in patients with diffuse ISR.

BACKGROUND: Many implants are being used for the reconstruction of orbital wall fractures. The effect of the choice of implant for the reconstruction of an orbital wall fracture on the surgical outcome is under debate. The purpose of this article is to compare the outcomes of orbital wall reconstruction of small orbital wall fractures on the basis of the implants used. METHODS: The authors conducted a retrospective study using electronic databases. Between March 2001 and December 2012, 461 patients with orbital wall fractures were included in this study. Among them, 431 patients in whom the fracture size was less than 300 mm2 were analyzed. The fracture size was calculated using computed tomography scans of the orbit in the sagittal and coronal images. Cases in which the fracture size was less than 300 mm2 were included in this study. RESULTS: One hundred and twenty-nine patients were treated with silastic sheets; 238 patients were treated with titanium meshes; and absorbable meshes were used in the case of 64 patients. Overall, 13 patients required revision, and the revision rate was 3.0%. The revision rate of the silastic sheet group was 5.4%. In the multivariable analysis, the revision rate of the group reconstructed with silastic sheets was highly statistically significant (P=0.043, odds ratio=3.65). However, other factors such as age, sex, fracture type, and fracture size were not significant. CONCLUSIONS: Reconstruction of orbital wall fractures with silastic sheets may cause more complications than that with other materials such as titanium meshes and absorbable meshes.

Pancreatic fistulae follows pancreatic duct disruption and may develop as a complication of pancreatic disease or injury. The escaping fluid may be walled off by the surrounding viscera to form a pseudocyst or an abscess. Fistulae may drain spontaneously into adjacent hollow viscera or communicate with the body surface externally. Although internal pancreatic fistulas that communicate with adjacent internal organs are much less common, vascular communication with the pancreatic ductal system is especially unusual and generally represents a serious clinical situation. We experienced one case of pancreatic duct-portal vein fistula in a patient with pancreatic cancer. Endoscopic retrograde cholangiopancreatography revealed a large vascular structure representing the portal vein filled at the time of the contrast injection, indicating the presence of a pancreatic duct-portal vein fistulae.

BACKGROUND: The majority of patients with locally advanced, unresectable, non-small cell lung cancer(NSCLC) were treated with conventional thoracic radiation therapy Throcic radiation therapy produces tumor regression in most patients but few cures and dismal 5-year survival rate. Several randomized studies have demonstrated that systemic chemotherapy controls micrometastasis and improve survival ratNes for patients who have locally advanced NSCI.C. Hut the optimal frequency of chemotherapy and sequence for chemotherapy and radiotherapy are yet to be determined. In this study, we analyzed response rate, median survival time, side effects and prognostic variables according to the frequency of chemotheray in locally advanced NSCLC patients. METHODS: We separated locally advanced, unresectable, NSCLC patients into two groups according to given number of chemotherapy cycles. Among 28 patients evaluated, eleven patients were classified to group A, receiving above 3 cycled chemotherapy and seventeen patients, classified to group B, receiving 3 cycled chemotherapy. In both groups, thoracic irradiation of 5940 cGy was given to all patients after chemotherapy. RESULTS: 1) Median survival time was 12.9 months for group A, 12.8 months for group B but there was no statistically significant difference(P>0.05), 2) Overall response rates were not significantly different between two groups(P>0.05). 3) Frequency rate of local failure and distant metastasis were not significantly different between two groups (P>0.05). 4) The grade and frequency of toxicities during treatment were not significantly different between two groups (P>0.05). 5) Clinical stage was the only major prognostic factor for overall survival (P<0.05). CONCLUSION: Median survival time, response rate, toxicities and frequency of local failure and distant metastasis were not significantly different between two groups. So, when we treat locally advanced, unresectable, NSCLC patients in sequential combined treatement, we should consider planned therapy(limiting chemotherapy cycles given), because planned therapy reduces many troubles of patients, that is, economic loss and time consuming, psychiatric anxiety etc, during treatment period. The optimal frequency of chemotherapy is remained to be validated in large scale study in the future in the setting of combined treatment.

PURPOSE: .In FSRT (Fractionated stereotactic radiotherapy) planning, we studied the usefulness between multiple arc FSRT and conformal FSRT by comparing tumor shape and DVH(dose volume histogram). MATERIALS AND METHDS: In Chungnam Univ. hospital, we had treated the sixteen patients with FSRT from Aug. 1997 to Dec. 1998. In choosing multiple arc FSRT or conformal FSRT, we had considered multiple arc FSRT if tumor shape was similar to sphere or the value of IF was less than 1.25, conformal FSRT if tumor shape was very irregular or IF was more than 1.3. For evaluation of treatment planning, we had considered the appropriate DVH for tumor volume and for critical organs. RESULT: The errors between reference point and the coordinates point on AP, Lat radiography were less than 1 mm before treatment. We had planned 3~5 arcs for multiple arc FSRT, 5~6pots for conformal FSRT. The mean dose distribution of tumor volume of cumulative DVH between multiple arc FSRT and conformal FSRT was 90.6, 86%, respectively. The dose of critical organs irradiated was less than 5% maximum dose of cumulative DVH. CONCLUSION: We had obtained the similar value between multiple arc FSRT and conformal FSRT, so that we had appropriate treatment planning of FSRT for multiple arc FSRT and conformal FSRT according to tumor shape and size.

BACKGROUND: This study presents a biomechanical and histometric comparison of bone response to implants with various area of hydroxyapatite(HA) coating. METHODS: The implants were placed in the tibia of 10 rabbits weighing 2.5-3.5kg. The control group had a machined surface, the experimental group 1 had 50micrometer thick HA coated in a band form, and the experimental group 2 had 50micrometer thick HA coated on the entire surface. 8 weeks after implantation, the animals were sacrificed. Removal torque was measured and histologic preparation was also performed for histologic and histometric analysis. Bone to implant contact as well as percentage of bone area inside threads were measured. ANOVA post hoc, and t-test were used for statistical analysis with p-value p<0.05. RESULTS: 1. The removal torques were 9.36 +/- 5.64 Ncm, 48.40 +/- 16.66 Ncm, and 82.37 +/- 22.56 Ncm for the control, exp. 1, and exp. 2 group respectively. Statistically significant difference were found among all the groups(p<0.05). 2. Bone to implant contact in the cortical bone were 38.94 +/- 10.9 %, 66.90 +/- 14.1 %, 73.00 +/- 19.4 %, in the marrow bone, 8.30 +/- 5.4 %, 14.59 +/- 5.9 %, 18.54 +/- 11.8 %, and in total, 22.40 +/- 10.1 %, 31.19 +/- 7.5 %, 41.41 +/- 12.2 % for the control, exp.1, and exp. 2 group respectively . In the cortical bone, exp. 1, and exp. 2 group showed statistically significantly higher contact compared to control group. Total contact and in the marrow bone, only exp. 2 group showed statistically significantly higher contact compared to control group(p<0.05). In all the groups significantly higher contact were observed in the cortical bone compared to the marrow bone(p<0.05). 3. Percentage of bone area inside threads in the cortical bone were 55.68 +/- 7.25 %, 55.19 +/- 13.19 %, 57.04 +/- 13.33 %, in the marrow bone, 12.34 +/- 14.61 %, 17.56 +/- 20.04 %, 20.26 +/- 12.83 %, and in total, 30.30 +/- 12.46 %, 31.57 +/- 15.15 %, 34.25 +/- 12.56 % for the control, exp.1, and exp. 2 group respectively. There was no statistical difference among the groups. In all the groups significantly higher bone area were observed in the cortical bone compared to the marrow bone(p<0.05)
