Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

PURPOSE: We investigated the efficacy of transurethral needle ablation (TUNA) of prostate for benign prostatic hyperplasia (BPH) in patients with low compliance to medical therapy and high risk operative morbidity and mortality. MATERIALS AND METHODS: Total 38 patients with BPH and low compliance to medical therapy and high risk operative morbidity and mortality were treated with TUNA under the local anesthesia and evaluated prospectively using the international prostate symtom score (IPSS), Qmax, satisfaction score and postvoid residuals (PVRs), and followed for 3 months after treatment. RESULTS: The mean pretreatment symptom score was 24.82+/-5.76. At 1 and 3 months after treatment, the mean symptom score was decreased to 13.63+/-7.07 and 9.21+/-6.28, respectively (p<0.01). The mean pretreatment satisfaction score was 4.63+/-0.85. It was decreased to 2.84+/-1.26, 1.92+/-1.34 at 1, 3 months (p<0.01). The mean pretreatment Qmax was 5.26+/-3.37mL/s. It was increased to 9.53+/-4.54mL/s, 11.97+/-4.52mL/s at 1, 3 months (p<0.01). The mean pretreatment PVRs were 131.85+/-123.05mL. It was decreased to 49.68+/-38.28mL, 26.77+/-17.92mL at 1, 3 months (p<0.01). CONCLUSIONS: TUNA treatment in the management of BPH improved symptom scores, peak flow rates with lower morbidity. TUNA appears to be a useful alternative treatment for BPH in patients with low compliance to medical therapy and high risk operative morbidity and mortality.

Great strides have been made not only in the research of the endogenous electrical signals,but also in the clinical application on nonunions using exogenous electrical signals. We measured human skin steady state potentials on the anteromedial surface of the twenty-eight left proximal tibiae and investigated intraosseous induced potentials created by a capacitively coupled signal applied on the proximal tibia of ten rabbits' right hind limbs. Following results were observed: 1. Human skin epiphysio-metaphyseal and epiphysio-diaphyseal potential differences in resting state were 116.1±11.7µV, and 120.5±29.4µV, respectively(P> 0.05), while those in full weight bearing were 310.3±169.4µV, and 404.2±154.1µV, respectively (P<0.05). 2. Skin steady state potentials were affected by muscle contraction and load bearing. 3. Thraugh a sequence of applied voltage of 2, 5, 10, 20, and 30 volts peak to peak, linear increase in the intraosseous induced potentials were produced. 4. Intraosseous induced potentials increased, although their increasing rates being decelerated, with increasing frequencies of 2, 20, 60, 120, and 200 KHz. 5. Higher intraosseous induced potentials were produced,as conductive jelly was applied between the capacitor plates and skin.

In Uremic condition, Secondary Hyperparathyroidism ensues due to phosphate retention, low level of calcitriol, decreased calcium absorption from intestine, skeletal resistance to the Parathyroid Hormone (PTH), hypocalcemia and eventually parathyroid hyperplasia. Theoretically, Reversal of hyperparathyroidism can be expected after successful kidney transplantation. However, Some patients show continuous increase of parathyroid function due to autonomous excretion of PTH, in which case, we could assume a tertiary hyperparathyroidism. There were sporadic reports for the treatment of tertiary hyperparathyroidism after successful kidney transplantation. And in some aspects, there remains a controvesrsy about the timing of parathyroidectomy. The occurrence of a single parathyroid adenoma after kidney transplantation is ever unusual finding. In our hospital, we have experienced a case of parathyroid adenoma who had taken successful kidney transplantation. The patient was 62 year old man who had a long duration of hemodialysis for 10 years. His hypercalcemic findings were managed medically for 1 year. As the patient's hypercalcemic symptom aggrevated, he was admitted and parathyroid adenoma was diagnosed by a CT scan and parathyroid scan. After excsion of the parathyroid adenoma, his general condition and kidney function improved. In our conclusion, there may be a debate for the timing of subtotal parathyroidectomy in the patient with tertiary hyperparathyroidism after kidney transplantation. But when the patient shows a hypercalcemic profile, the parathyroid scan, CT scan, Neck Ultrasonography must be considered to detect single parathyroid adenoma which is so simple to remove surgically.

PURPOSE: We investigated how tumor angiogenesis correlates with other prognostic features i. e. histologic grade and tumor stage, also evaluated whether microvessel density(MVD) has predictability of disease progression for T1 lesions and could be used for patients selection of early intervention. MATERIALS AND METHODS: We retrospectively reviewed the records of 62 patients with transitional cell carcinoma(TCC) of the bladder and counted microvessels by immunohistochemisty using antibody for CD34 antigen. The extent of tumor-associated angiogenesis in specimen was evaluated by immunohistochemical methods using HPCA-1, a mouse monoclonal antibody directed against the endothelial cell antigen, CD 34. The number of microvessels in a 200x microscopic high power field (hfp) containing the area of greatest neovascularization within or immediately adjacent to each tumor determined. RESULTS: In bladder tumor, the MVD did not correlate to the increase of histologic grade (54.0+/-25.3 for grade 0 (n=7), 90.5+/-22.8 for grade 1 (n=12), 94.5+/-33.9 for grade 2 (n=17), 109.5 +/-37.6 for grade 3 (n=26)) and stage (47.0+/-26.3 for Ta (n=8), 92.7+/-23.8 for T1 (n=31), 112.4+/-46.4 for T2 (n=9), 98.4+/-30.3 for T3 (n=7), 123.5+/-43.7 for T4 (n=7)). But MVD in grade 0 and Ta were lower than any other grades and stages. MVD in progressive G3T1 (n=9) was higher than that of non-progressive G3T1 (n=8)(p<0.05, 131.1+/-49.0 vs 94.5+/-32.8). CONCLUSIONS: There was no significant relationship among the mean vessel count and tumor grade and stage. But grade 0 and stage Ta were significantly lower microvessel counts than any other grade or stage. Remarkably decreased angiogenesis in grade 0 and stage Ta bladder tumor suggested that angiogenesis in bladder tumor may appear as the early step in tumor formation. Microvessel density in progressive superficial TCC was higher than that in nonprogressive superficial TCC. It was suggested that increased MVD in the specimen of TURBT may predict tumor progression.
