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 evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

9.Effect of Doxapram on the Recovery from Vecuronium from Vecuronium of Mivacurium-induced Neuromuscular block in the Rabbit.
Korean Journal of Anesthesiology 1995;28(4):548-554
Doxapram as a potent respiratory stimulant is one of attempts to solve respiratory problem and has been known to be effective for many years. But one study suggested that the presence of doxapram retarded neostigmine-induced antagonism of vecuronium effect. So we studied the effect of doxapram on the reverse of neuromuscular block when doxapram was injected with different dose. 60 rabbits were divided into 6 groups. Vecuronium was used in Group 1~3 and Mivacurium was used in Group 4~6 as a muscle relaxant. When the first twitch of TOF response reappeared from the complete block with a muscle relaxant (T1 onset), we administered neostigmine 0.05 mg/kg and saline 0.3 ml i.v. in Group 1, 4(VS, MS), neostigmine 0.05 mg/kg and doxapram 0.5 mg/kg i.v. in Group 2, 5(VDP1, MDP1), and neostigmine 0.05 mg/kg and doxapram 3 mg/kg i.v. in Group 3, 6(VDP2, MDP2). Two recovery time, from T1 onset to T1 25% and from T1 25% to T1 75%, and TR(ratio ; T4 twitch/T1 twitch) at T1 75% were measured. For the hemodynamic effect of doxapram, Blood pressure, heart rate and arrythmia were observed before and after doxapram injection too. The results are as follows. 1) Recovery time from T1 onset to T1 25% are 2'30"+/-0'29"(min'sec") in VS, 3'07"+/-0'4l"(minsec") in VDPl, 1'49"+/-0'17"(min'sec") in VDP2, 2'34"+/-0'17"(min'sec") in MS, 2'41"+/-0'25"(min'sec") in MDP1, 1'52"+/-0'39"(min'sec") in MDP2. 2) Recovery time from T1 25% to T1 75% are 4'58"+/-0'52"(min'sec") in VS, 6'10"+/-1'17"(min'sec") in VDP1, 3'38"+/-0'33"(min'sec") in VDP2, 4'38"+/-'0'57"(min'sec") in MS, 5'10"+/-0'55"(min'sec") in MDP1, 3'15"+/-0'38"(min'sec") in MDP2. 3) TR at T1 75% are 76.6+/-7.7% in VS, 82.4+/-3.4% in VDP1, 83.8+/-4.5% in VDP2, 81.4+/-2.3% in MS, 89.8+/-2.3% in MDP1, 89.8+/-1.5% in MDP2. 4) Heart rate, cardiac rhythm, systolic and diastolic pressure before and after doxapram injection were not significantly changed. In conclusion, simultaneous administration of neostigmine and low dose doxapram delayed recovery from the neuromuscular block, but high dose doxapram did not.
