BACKGROUND: The length of postoperative drug therapy remains controversial in pulmonary tuberculosis. We analyzed our experiences to determine the postoperative duration of chemotherapy after resection. METHODS: A retrospective review was performed in 66 of 95 patients that underwent pulmonary resection for pulmonary tuberculosis between January 1993 and December 1998. We compared the relapse rates according to the length of postoperative chemotherapy in each group, classified by the results of sputum AFB culture before the surgery, the number of resistant durgs, the number of prior treatment and the division of anti-TB drugs used postoperatively. RESULTS: Fifty three of 66(80.3%) were men and 13(19.7%) were women with a median age of 33.5 years(range, 16 to 63). The mean lengths of the pre-and post-operative chemotherapies were 4.9 months, and 12.9 months respectively. Five of 66 patients(7.6%) relapsed during the mean period of follow up(39.7 months). In the group less than three times of the prior treatment, there were two relapses(20%) in Ed-the highlight above-rephrase 10 patients that were medicated for 6 months or less, and one relapse in 43 patients(2.3%) that took medicine for more than 6 months(p=0.03). In the group using second-line drugs postoperatively, there was one relapse(25%) in four patients that were medicated for 12 months or less. No patient in a total of 17 that received medicine for more than 12 months relapsed(p=0.03). CONCLUSION: We recommend that patients with the prior treatment less than three times should be treated for more than 6 months after resection and patients using the second-line drugs postoperatively should be medicated for more than 12 months.

Systemic lupus erythematosus is a systemic disorder which has frequent involvement of gastrointestinal tract. Non specific symptoms such as anorexia, nausea, diarrhea and abdominal pain are well known symptoms when the gastrointestinal tract is involved. The most feared gastrointestinal complication of systemic lupus erythematosus is lupus enteritis. The pathological change in lupus enteritis is usually a result of mesenteric vasculitis. Major complications such as intestinal bleeding and perforation may occur and sometimes result in sugery. Because of high mortality rate in case of major complications, early diagnosis and appropriate treatment is very important. We experienced three patients with lupus enteritis who presented with severe abdominal pain and dirrhea. They were diagnosed by characteristic radiographical findings of small bowel series and barium study. All radiographical findings has been resolved completely with the steroid therapy. Conclusively we can induce complete remission by steroid therapy alone, if we diagnose lupus enteritis in the early period of disease course.

In this report we describe twenty-two cases of intracranial tumors studied with an MR imager operating at a field strength of 0.064 T for evaluation of the clinical utility of low tesla MRI. The comfirmed diagnoses were meningioma(9 cases), astrocytoma(4 cases), glioblastoma multiforme(1 case), craniopharyngioma(2 cases), intracranial metastasis(1 case). pituitary microadenoma (1 case), hemangioblastoma (1 case), and trigerminal neurilemmoma(1 case). Meningiomas appeared as well-marginated, homogenous signal intensity masses(67%) in most cases. Most meningiomas showed iso-signal intensity(78%) on T1-weighted images, and high signal intensity on T2-weighted images. After Gd-DTPA enhancement, diffuse homogeneous contrast enhancement(75%) was well see. The multiple hemorrhagic foci within the glioblastoma multiforme were identified, which shoed high signal intensity on T1-weighted images and low signal intensity on T2-weighted images(intracellular methemoglobin), or high signal intensity on both T1 and T2-weighted images(extracellular methemoglobin). One case of cerebellar hemangioblastoma was a well-defined cystic mass with contrast enhanced mural nodule but no identification of characteristic signal void vessels. The remianing tumors showed low signal intensity on T1-weighted images, and high signal intensity on T2-weighted images. Gd-DTPA enhancement was helpful in separating the lesion from the surrounding edema or normal tissue, but had limited diagnostic value in characterizing the nature of the mass. The advantages of low tesla MRI are as follows on requirement of cooling water or electricity, open design, shorter T1 relaxation time compared with high tesla unit that increases the difference of T1-relaxation time between tissues, ease of installation, and cost effectiveness. In conclusion, the low tesla MRI is useful for the detection and evaluation of the brain tumors.

PURPOSE: We reviewed the results of endoureterotomy and balloon dilation for benign ureteral strictures to determine the efficacy of these procedures. MATERIALS AND METHODS: We treated 19 patients who had benign ureteral stricture by retrograde endoureterotomy or balloon dilation followed by placement of a 6-8Fr stent for 6 weeks. Mean follow up period was 14 months (6-27 months). Eight patients were treated by endoureterotomy using cold knife under direct vision and 11 patients were treated by balloon dilation. The causes of ureteral strictures were abdominal surgery in 8 patients, urinary tuberculosis in 6 patients, radiation therapy in 2 patients, rigid ureteroscopy in 2 patients and periureteral abscess in 1 patient. The length of strictures was shorter than 1cm in 14 patients and over 1cm in 5 patients. The etiology of strictures was ischemic origin in 11 patients and nonischemic in 8 patients. One patient had poor ipsilateral renal function (<25%). RESULTS: The overall success rate was 78.9% (15/19). The success rate of balloon dilation was 81.8% (9/11) and that of endoureterotomy was 75% (6/8). No significant complication such as high fever or sepsis was observed. Strictures shorter than 1cm had 92.9% (13/14) success rate while strictures over 1cm had 40% (2/5) success rate (p <0.05). The nonischemic strictures had better success rate (87.5%) compared to ischemic strictures (72.7%) without statistical significance. CONCLUSIONS: We would suggest the use of balloon dilation or endoureterotomy as the initial treatment of benign ureteral stricture regarding the safety and efficiency. The better outcome would be expected in the strictures shorter than 1cm in length.

From February 1996 to May 1997, 18 patients underwent mitral valve repair for mitral regurgitation. There were 9 male and 9 female patients aged from 19 to 68 years (mean, 53). Thirteen patients were in New York Heart Association (NYHA) class III and IV. The cause of mitral regurgitation was degenerative in 12 patients, rheumatic in 5 patients and infective in 1 patient. Fifteen patients were in Carpentier's functional classification II, 2 patients in Carpentier's class III and 1 patient in Carpentier's class I. Surgical procedures included prosthetic ring annuloplasty (16 cases), rectangular resection of posterior leaflet (15 cases), chordal shortening (5 cases), triangular resection of anterior leaflet (2 cases), commissurotomy (2 cases), partial transposition of posterior leaflet (1 case). These procedures were combined in most patients. There was no operative death. These patients have been followed from 1 to 15 months, mean of 6.7 months. There was one late death resulted from low cardiac output following mitral valve replacement. The function of the repaired valve in other 17 patients has remained satisfactory during the observed interval. We consider that mitral valve repair is highly satisfactory in patients with mitral regurgitation.

PURPOSE: To evaluate the effects and usefulness of fiuroscopy guided celiac ganglion block after marking of needle path with CT scan. MATERIALS AND METHODS: Celiac ganglion block with 100% ethyl alcohol was performed in 50 cancer patients who were inoperable and had intractable abdominal pain. Duration and degree of pain relief after the procedure and its complication were analyzed. RESULTS: Early pain relief was observed in 98% and long term relief in 68% without serious complication. CONCLUSION: Fluoroscopy guided celiac ganglion block after marking of needle path with CT scan was a safe and valuable procedure in relieving intractable pain in terminal cancer patients and reduced the time in the CT room.
