A new hypolipidemic agent, lovastatin, hydroxy-methyl-gultaryl coenzyme A reductase inhibitor was administred to 25 patients with primary hyperlipidemia 20 to 40 mg daily for 12 weeks and sequential changes of serum lipid profile were analysed as follow. 1) Mean average at baseline period of serum total cholesterol, triglyceride, HDL and low desity lipoprotein cholesterol were 271, 179, 51 and 185 mg/dl respectively. 2) Total cholesterol showed 20% decrease at 4th week and 23% decrease at the end of 12th week while low density lipoprotein cholesterol decreased 31% and 33% respectively. 3) Triglyceride dropped 7% at 8th week and 3% at 12th week. High density lipoprotein cholesterol increased 4% at 4th week and showed 2% decrease at the end of study. 4) Only one patient complained of moderate abdominal pain, which subsided after 2 weeks drug withdrawal. In conclusion, lovastatin was well tolerated and effective, in the treatment of primary hyperlipidemia.

PURPOSE: The purpose of this study was to prospectively evaluate the detectability and usefulness of automated whole breast ultrasound (AWUS) and to compare it with handheld breast ultrasound (HHUS) in cases with suspicious microcalcifications identified by mammography. METHODS: Forty-two patients with 43 suspicious microcalcifications (25 malignant and 18 benign) detected by mammography underwent AWUS, HHUS, and histol-ogic examination. With knowledge of the mammographic findings, HHUS was performed to assess the visibility of the microcalcifications and the presence of associated masses or ductal changes. Two radiologists reviewed the AWUS images in consensus using the same methods employed for HHUS. Detectability of AWUS was compared with that of HHUS and was correlated with histologic and mammographic findings. RESULTS: Of the 43 lesions, 32 (74.4%) were detectable by AWUS and 31 (72.1%) by HHUS. No significant differences in sensitivity were found between the two methods (p=0.998). AWUS detected 96% (24/25) of malignant microcalcifications and 44.4% (8/18) of benign microcalcifications. AWUS was more successful in the detection of malignant vs. benign lesions (96.0% vs. 44.4%, p=0.002), lesions >10 mm vs. ≤10 mm in size (86.7% [26/30] vs. 46.2% [6/13], p=0.009), lesions with a fine pleomorphic or linear shape vs. a round or amorphous or coarse heterogeneous shape (94.7% [18/19] vs. 58.3% [14/24], p=0.021), and lesions associated with a mass or architectural distortion vs. without obvious changes on mammography (100% [19/19] vs. 54.2% [13/24], p=0.022). CONCLUSION: Detectability of AWUS was comparable to that of HHUS in cases where suspicious microcalcifications were identified on mammography. Therefore, AWUS might be helpful in the performance of ultrasound-guided percutaneous procedures for highly suspicious microcalcifications.

PURPOSE: To evaluate the magnetic resonance imaging (MRI) and clinicopathological features of triple negative breast cancer, and compare them with those of non-triple negative breast cancer. MATERIALS AND METHODS: This study included 231 pathologically confirmed breast cancers from January 2007 to May 2008. We retrospectively reviewed the MRI findings according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon: mass or non-mass type, mass shape, mass margin, non-mass distribution, and enhancement pattern. Histologic type, histologic grade, and the results for epidermal growth factor receptor, p53, and Ki 67 were reviewed. RESULTS: Of 231 patients, 43(18.6%) were triple negative breast cancer. Forty triple negative breast cancers (93.0%) were mass-type lesion on MRI. A round or oval or lobular shape (p=0.006) and rim enhancement (p=0.004) were significantly more in triple negative breast cancer than non-triple negative breast cancer. In contrast, irregular shape (p=0.006) and spiculated margins (p=0.032) were significantly more in non-triple negative breast cancer. Old age (p=0.019), high histologic grade (p<0.0001), EGFR positivity (p<0.0001), p53 overexpression (p=0.038), and Ki 67 expression (<0.0001) were significantly associated with the triple negative breast cancer. CONCLUSION: MRI finding may be helpful for differentiation between triple negative and non-triple negative breast cancer.

PURPOSE:BK virus associated nephropathy (BKVAN) affects 1-10% of kidney transplant (KT) patients and it produces a progressive destruction of allograft. Reducing immunosuppression is the only way to save the graft, while it needs tight monitoring of the graft rejection and graft survival is poorer in advanced case. Leflunomide has immunosuppressive effect and also antiviral activity. Addition of leflunomide may improve BK virus clearance and graft survival. METHODS:6 KT patients with biopsy proven BKVAN (Histological pattern B) were treated with leflunomide and reduced immunosuppression. All patients were monitored with serial determination of viral load in blood and graft function. RESULTS:BKVAN was diagnosed at 14 months (7-28) post transplant, at that time median serum creatinine concentration was 2.8 mg/dL (1.8-3.6). 12.5 months (6-16) later of leflunomide treatment, median serum creatinine was 2.3 mg/dL and no graft loss was found. CONCLUSION:Leflunomide therapy with reduced immunosuppression may be effective in the treatment for BKVAN.

A 35-year-old multigravida woman received triple marker screening tests in 16weeks 2days of gestation. MSAFP and MShCG values were increased, whereas MSuE3 value was decreased. So we performed amniocentesis for karyotyping and confirmed male fetus with 47,XYY,inv(9)(p11:q13). A neonatal survey showed the incidence of XYY male to be approximately 1:1000, the majority of cases are phenotypically normal. XYY males are taller than normal and show delayed mental development. A pericenteric inversion of chromosome 9 that extends from p11 to q13 is considered a normal chromosome variant, but the carrier is at high risk to produce abnormal offspring. As she did not want to terminate her pregnancy, she delivered vaginally in 39weeks 6days of gestation. As a result of physical examination, the neonate showed a normal phenotype. We report it with brief review.

PURPOSE: The aim of this study was to evaluate the usefulness of MRI performed after excisional biopsy to diagnose residual cancer and additional lesions. MATERIALS AND METHODS: A total of 16 patients who had breast cancer diagnosed by excisional biopsy underwent preoperative breast MRI between March 2005 and August 2007 were included. MRI findings were considered positive for residual cancer if focal, thick, or irregular rim enhancement or adjacent enhancing lesion was identified around the postoperative biopsy cavity. And additional lesions separated from biopsy cavity including multifocal, multicentric, or contralateral lesion were evaluated. We evaluated the diagnostic accuracy of MRI, comparing MRI with histopathologic finding, and the impact of MRI on surgical planning. RESULTS: The sensitivity and specificity of MRI for detecting residual disease considering rim enhancement were 85.7%(6/7) and 55.6%(5/9). Additional lesions including multifocal, multicentric, or contralateral lesion were found in 6 patients. In 7 patients, results of MRI findings changed surgical treatment planning. CONCLUSION: The pattern of rim enhancement on MRI after excisional biopsy is not differential point to evaluate remnant lesion. But MRI has an important role to help the detection of multifocal or multicentric, or contralateral breast malignancies, resulting in beneficial change in surgical treatment planning.

BACKGROUND: Inhalation anesthetics are an important factor for postoperative hepatic and renal dysfunction. In this regard, TIVA can reduce the risk of hepatic and renal dysfunction inherited to inhalation anesthetics. The present study was conducted to determine whether hepatic and renal functions differ after anesthesia with sevoflurane and propofol. METHODS: Two hundred patients, ASA physical status class I, II, scheduled for an elective thyroidectomy were randomly divided into two groups. Anesthesia was maintained with sevoflurane 1-2% and remifentanil in the sevoflurane group (Group S) and propofol 2-5 ug/ml and remifentanil 2-5 ng/ml at the effect site, using a target controlled infusion (TCI) pump in the TIVA group (Group T) to maintain BIS of 40-60. To evaluate the hepatic and renal function, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine were tested at preoperation (baseline), postoperative 1 day and 3 days. RESULTS: AST was increased at postoperative 1 day and 3 days, compared with that of the preoperation in Group S, and postoperative 1 day in Group T, but the values were within its normal limit. ALT was not changed after anesthesia in both groups. BUN was increased at postoperative 1 day, compared with that of the preoperation in Group S, but the value was within its normal limit. Creatinine was not changed after anesthesia in both groups. CONCLUSIONS: The changes of hepatic and renal function after inhalation anesthesia with sevoflurane and TIVA with propofol and remifentanil for thyroidectomy were clinically insignificant, and there was no difference between the two methods.

INTRODUCTION: Most of the palatal fistulas develop along the suture line in a small size, so they can be corrected easily by re-palatoplasty or various flap surgery using the local mucoperiosteum. But it is very difficult to repair if the fistula is very large or located anterior to the hard palate. Buccal mucosal or vestibular mucosal flaps may settle the problems but there are many limitations on the size and location. And other extraoral distant flaps need not only many surgical steps but also cause inconvenience. But tongue flap proffers as an excellent method for the repair of large anterior palatal fistula because of highly mobility and rich blood supply and low donor site morbidity. MATERIALS & METHODS: We treated the six cases of large palatal fistulas using the distally based tongue flap. We dissected under the submucosa layer around fistula site preserving the mucoperiosteum and the elevated flap was rotated to nasal side and sutured with 4-0 Vicryl(R) for the repair of the nasal side. And then we elevated the tongue flap on the distal portion of the tongue. The elevated tongue flap was placed on the defect area and sutured with 4-0 Chromic(R). After 2 or 3 weeks, we detached the tongue flap which was placed on the fistula site. Donor site was closed with 4-0 Chromic(R). RESULTS: The mean size of palatal fistula was 7.2 cm. All of patients complained the discomforts in masticating and speaking before flap detaching operation. A wound dehiscence was observed on tongue flap sutured to defect site. But it was healed by revisionary suture. There was no donor site complication. CONCLUSION: The authors propose that the distally based tongue flap is an excellent method for the repair of large palatal fistula because of its highly mobility, rich blood supply, and few of donor site morbidit
