BACKGROUND: There is a well recognized interlaboratory variation in the results using the polymerase chain reaction(PCR) to detect the IS6110 sequence. The clinical utility of a commercially developed PCR test(Amplicor) in bronchial washings for detecting pulmonary tuberculosis in smear negative patients was evaluated. The sensitivity and specificity of Amplicor was compared with that of an in-house PCR test used for detecting the IS6110 sequence of Mycobacterium tuberculosis(M.tbc) in the bronchial washing fluid. METHODS: 66 patients whose sputum smear for M.tbc were negative or who could not produce any sputum were recruited from January 1999 to July 1999. They all had a bronchoscopy performed to determine if there were signs of hemoptysis, patients who could not cough up sputum, lung lesion that exclude pulmonary tuberculosis. Pulmonary tuberculosis was diagnosed on the basis of a positive culture or a response to anti-tuberculosis therapy. RESULTS: 19 patients with tuberculosis were identified and samples from 16 patients were later confirmed by culture. Bronchial washing for Amplicor PCR revealed a sensitivity, specificity, positive and negative predictive values of 94.7%, 97.9%, 94.7%, 97.9%, respectively. Using IS6110 based PCR, the sensitivity, specificity, positive and negative predictive values were of 73.7%, 87.2%, 70%, 89.1% respectively. CONCLUSION: Bronchial washing for Amplicor PCR proved to be more useful than IS6110 based PCR in rapidly diagnosing smear negative pulmonary pulmoary tuberculosis in patients where tuberculosis was likely to be differential and rapid diagnosis was essential for optimal treatment.

We have analyzed clinical results of forty-five patients who had spondylolisthesis which were operated using transpedicular screw fixation devices (CD or Steffee VSP system) between June, 1987 and March, 1992 at the department of Orthopedic Surgery of Kwang-ju Christian Hospital. Simultaneously we compared the postoperative results between two groups. The results were as follows: 1. The ratio of man and woman was 1: 2.2 and mean age was 44.3 years (44.8 years in degenerative type and 42.5 years in isthmic type). 2. The most common level was L4 on L5 and two-third of all cases were isthmic type. 3. The clinical results were satisfactory in 91% (41 cases) according to anthors modified evaluation system. There was no significant difference between degenerative and isthmic type. 4. The mean % of slip was improved from 23.3% preoperatively to 7.4% postoperatively and the mean slip angle was improved from 3.5 degrees preoperatively to-5.4 degrees postoperatively. 5. The devices which were used for operation were C-D instrument in 21 cases and Steffee VSP system in 23 cases. There was no difference in radiographic examinaton and clinical result between two groups. 6. The anterior fusion was done for 9 active young patients. The results were significantly satisfactory. 7. We consider the transpedicular fixation system is the most recommandable method of treatment for spondylolisthesis in providing excellent reduction of slippage and maintenance of reduction with rigid fixation device.

PURPOSE: To elucidate whether there is a delay of adjuvant treatment or detection of recurrences, or an increasing of the recurrence of tumorsin clinically advanced breast cancer patients. METHODS: The study group included 55 patients underwent mastectomy with immediate reconstruction (IBR), and 563 patients who received the mastectomy without reconstruction (non-IBR), and who were stage IIB and IIIA breast cancer patients, at Asan Medical Center between Jun 1993 and December 2000. We retrospectively assessed the comparative outcomes through using follow-up data. RESULTS: Out of 2,057 patients who had undergone the mastectomy on during the period, 175 (8.5%) underwent immediate reconstruction. 55 of them (31.6%) were stage IIB and IIIA patients, a similar portion (29.9%) was seen in the 563 patients of same stages without reconstruction. The mean ages of these groups were 37.1 and 46.9 years, that is, the reconstruction group was about 10 years younger. All these patients voluntarily underwent immediate reconstruction. For the patients who were followed up, the local recurrence was 3.6% (2/55) for the IBR group and 5.2% (29/563) for the non-IBR group. On the other hand, the distant relapse rates were 12.7% and 13.9%. The administration of adjuvant chemotherapy was not delayed and radiotherapy was used as an adjuvant treatment after reconstruction in nine of the cases (16.4%). Chemotherapy was also conducted in 98.2% of the IBR group and 77.3% of the non-IBR group. While radiotherapy was used in the IBR group less frequently, there was no statistical difference between the two groups (P=0.63). CONCLUSION: Immediate reconstruction following mastectomy for the treatment of breast cancer is now more frequently performed. IBR can be done in clinically advanced breast cancer without increasing the risk of treatment failure or modification.

PURPOSE: To compare the clinical therapeutic efficacy of finasteride and dutasteride as 5-alpha reductase inhibitor (5-ARI) in the medical treatment of benign prostate hyperplasia. MATERIALS AND METHODS: From July 2007 to July 2010, 354 benign prostatic hyperplasia patients with combination medication : alpha blocker plus 5-ARI were enrolled. These patients were classified into a finasteride medication group (F group) and dutasteride medication group (D group) retrospectively. We initially measured the total prostate volume (TPV), prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), quality of life score (QoL), maximal flow rate (Qmax), and post-void residual urine (PVR). After at least twelve months of medication, we rechecked these clinical parameters and during medication, side effects related to medication were also recorded. RESULTS: The F group (n=129) and D group (n=225) showed no differences in baseline characteristics for age, TPV, IPSS, QoL scores, or PSA. After medication, decreases in TPV were relatively higher in the D group than the F group (28.2% vs 20.5%). In addition, the decrease in PSA (43.6% vs 39.2%) and IPSS score (4.6 vs 3.5) were also higher in the D group. There were no significant differences in QoL score, Qmax, PVR change, or side effects between the two groups. CONCLUSIONS: Dutasteride showed greater efficacy in reduction of TPV and PSA and in symptomatic improvement by IPSS score than finasteride. More large scale studies about the differences on clinical efficacy of finasteride and dutasteride are needed.

OBJECTIVE: The purpose of the current series of experiments were to assess the effect of GM-CSF, as a medium supplement, on the development of mouse embryos and the expression of LIF and IL-1beta mRNA. MATERIALS AND METHODS: Mouse 2-cell embryos were collected from the oviducts of 6 weeks old ICR mice at 48 hours after hCG injection. Embryos were cultured in P-1 medium supplemented with mouse GM-CSF(0,1,5,10 ng/ml). The embryo development to blastocysts and hatching blastocysts was assessed and the cell number in blastocyst was also examined. Using RT-PCR, the expressions of LIF and IL-1beta mRNA in blastocyst were evaluated in the GM-CSF supplemented group and control group. RESULTS: In mouse, the addition of GM-CSF increased the percentage of blastocysts(65.5%, 68.6%, 73.0% and 76.1% for control and 1, 5 and 10 ng/ml, respectively), and increased the proportion of hatching blastocysts(35.2%, 36.4%, 43.2% and 53.0% for control and 1, 5 and 10 ng/ml, respectively). The mean cell numbers in blastocyst were significantly increased in GM-CSF supplemented groups compared to control group. LIF and IL-1beta expression in blastocysts were significantly higher in GM-CSF supplemented group than in control group. CONCLUSION: The results of experiment by mouse embryos showed beneficial effects of GM-CSF as a medium supplement. Furthermore, the addition of GM-CSF significantly increased the expression of LIF and IL-1beta in mouse embryos. These results suggest that GM-CSF might be a important molecule in embryo implantation.
