A clinical evaluation of the chemotherapy (INH, PAS and SM) on the 16 patients with renal tuberculosis for the period of 9 months to 4 years was performed. The results obtained were summarized as follows; 1) Of the 16 cases with renal tuberculosis, minimal lesion was found in only one case. moderately advanced in 6, and far advanced in 9. 2) In the case of the minimal lesion, no tubercle bacilli were detected by microscopic examination .after the triple therapy for 3 months. It was suggested that the minimal lesion would require at 1eaet 6 months to be cured by the chemotherapy. 3) Five of the 6 cases with the moderately advanced lesion were cured (83%), and at least 12 months were required for the moderately advanced lesion to be cured. 4) In the 9 cases of the far advanced lesion, only one case was cured, two were on the healing process, three were exacerbated even after the therapy for 6 months, and the remaining three were progressed to those with non-visualizing kidneys 9 to 12 months after the therapy. 5) Five of the 6 exacerbated far advanced lesions were associated with ureteral strictures, and thus the ureteral stricture may be an important factor in determining the prognosis of the renal tuberculosis. For the far advanced lesions progressed to the non-visualizing kidneys in spite of the chemo-therapy, surgical interventions are likely to be more favorable.

Among the 63 patients with histopathologically proven primary squamous cell anal cancer who were managed in Presbyterian Medical Center and Yonsei University Cancer from Jan. 1971 to Dec. 1991, 34 patients, who were managed with surgery alone (abdominoperineal resection) or post-operative radiotherapy and concurrent chemoradiotherapy were analyzed. With mean follow up time of 81.3 months, 30 patients (88%) were followed up from 17 to 243 months. In methods, 10 patients were treated with surgery alone. 9 patients were treated with combined surgery and postoperative radiotherapy (59~60 Gy in 28~30 fractions). 15 patients were treated with concurrent chemoradiotherapy. Chemotherapy (Mitomycin C 15 mg/squ, bolus injection day 1;5-FU, 750 mg/squ, 24hr infusion, day 1 to 5) and radiotherapy started the same day. A dose of 30 Gy was given to the tumor and to the pelvis including inguinal nodes, in 15 fractions. After 2 weeks a boost of radiotherapy (20 Gy) to the ano-perineal area and second cycle of chemotherapy completed the treatment. The overall 50year survival rate was 56.2%. concurrent chemoradiotherapy group was 70% and surgery alone group was 16.7%. According to the cox proportional harzard model, there was significant different between survival with concurrent chemoradiotherapy and surgery alone (p=0.0129), but post-operative radiotherapy was 64.8%, which was not stastically significant (p=0.1412). In concurrent chemoradiotherapy group, the anal function preservation rate was 87% and the severe complication rate (grade 3 stenosis and incontinence) was 13.3%. In conclusion, we conclude that the concurrent chemoradiotherapy may be effective treatment modality in patients with anal cancer

Non-operative palliative treatment for malignant colonic obstruction can sometimes be accomplished by the insertion of anorectal tube, endoscopic balloon dilation or endoscopic laser therapy. But these methods have some disadvantages, such as limitaation of activity, need of repetitive treatment and high-risk of perforation. Endoscopic prosthesis is generally accepted as a safe, effective palliative treatment for malignant esophageal stricture, because this method has no above disadvantages. Neverthless, there is only a few experence with endoecopic prosthesis in malignant colorectal stricture over the world. We report two cases which were safely, effectively performed endoscopic prosthesis in palliative treatment for their malignant rectal strictures.

Placement of the self-expandable metallic stents for palliative treatment of malignant esophagogastric strictures has been thought to be easy, fast and effective method than conventional methods (bypass procedures, radiation therapy, laser treatment, esophageal intubation, etc.). The expandable metallic stent tubes were found to overcome some of the limitations of nonexpandable conventional tubes. Their implantation is better tolerated and safer than that of nonexpandable tubes, because the risks of migration and perforation are lower.On our knowledge, there has been no report of pyloric obstruction after this metallic stent insertion.We hereby report a case of pyloric obstruction caused by a migrated self-expandable metallic stent for palliative treatment of malignant esophageal stricture.

Various different objects have been reported to strangulate the penis. We reported on a patient who used metal radiator clamps for an extended period of time. Workup included history, physical examination and urinalysis. The patient was taken to the operating room for further evaluation with cystourethroscopy and orthopedic wire cutters were used to break the metal bands.

The efficacy and safety of catheter ablation for the management of atrial fibrillation (AF) has been improved in recent years. Radiofrequency (RF) catheter ablation for maintaining sinus rhythm is superior to the current antiarrhythmic drug therapy in selected patients. Pulmonary vein isolation (PVI) is the cornerstone of various catheter ablation strategies. It is well recognized that pulmonary vein (PV) antrum contributes to the AF initiation and/or perpetuation. Since PV stenosis is a complication of ablation within a PV, the ablation site for PVI has shifted to the junction between the left atrium and the PV rather than the ostium of the PV. However, PV reconnection after ablation is the major cause of recurrence of AF. The recovery of PV conduction could be caused by anatomical variations such as the failure to produce complete transmural lesion or gaps at the ablation line due to the transient electrophysiologic effects from the RF ablation. In this review, we discussed several factors to be considered for the achievement of the best PVI, including clinical aspects and technical aspects.
