PURPOSE: Breast cancer is second most common cancer in women. Most of the patients with breast cancer treated with mastectomy take breast reconstruction. Nipple reconstruction is an important step in breast reconstruction. Many surgeons have investigated of nipple reconstruction using the flap technique after breast reconstruction with the autologous tissue. The objective of this study is to evaluate the results of nipple reconstruction using the C-V flap technique after breast reconstruction only with the breast expander. METHODS: From April 2006 to May 2008, the authors treated 17 patients of nipple reconstruction using C-V flap technique, who received breast reconstruction only with the breast expander. As we have predicted decrease in the size of reconstructed nipple, we designed flap a little larger than wanted nipple size. Nipple splint was applied for 4-6 months for minimizing decrease of the size of reconstructed nipple. The diameter and height of the reconstructed nipple were measured and patient's satisfaction score was assessed. RESULTS: Mean follow-up duration was 12.5 months. Among the 17 patients, the average absorption rate by height of nipple was 47.0%. Partial necrosis was noted in 1 case, and treated well with conservative management. There were no other significant complications noted. Patient's satisfactory score was assessed by the height, design and location of the nipple. The average of satisfaction score was 85%, 68%, 62% and total average was 83%. CONCLUSION: The authors experienced 17 patients of nipple reconstruction using the C-V flap technique after breast reconstruction only with the breast expander. The absorption rate of the size of the nipple, complications and patient's satisfactory score of this study were similar to those of nipple reconstruction after breast reconstruction with the autologous tissue. It is expected that nipple reconstruction after breast reconstruction only with the breast expander is safe and reliable. It is considered that a long-term study is necessary.

PURPOSE: Gynecomastia is an abnormal increase in the volume of the male breast. Subcutaneous mastectomy was the first surgical treatment for gynecomastia. But because of the complications such as nerve injury and scar formation, subcutaneous mastectomy has been substituted with liposuction. Recently various techniques including ultrasound-assisted liposuction has been used for treatment of gynecomastia. The purpose of this study is to evaluate the results of XPS(R) microresector (Shaver) for treatment of gynecomastia. METHODS: 17 patients, 33 breasts of gynecomastia, Simon grade I or II have been treated with XPS(R) microresector (Shaver). The mean age was 24.5. The subcutaneous tissue and glandular tissue were removed with XPS(R) microresector (Shaver). The operation time, the weight of removed tissue and patients' satisfaction score were accessed. RESULTS: The mean operation time was 78.2 minutes. The mean weight of removed tissue was 113.8 g. There were no significant complications such as necrosis, hematoma, infection or scar contracture. Patients' satisfactory score of scar, shape and confidence were 8.4, 8.2 and 8.4 respectively. As the average score was 8.3, most of the patients were satisfied with their breasts. CONCLUSION: The authors have treated 17 patients suffering from gynecomastia with XPS(R) microresector (Shaver). We obtained short operation time, early recovery, minimal operative scar and less complications with XPS(R) microresector (Shaver) for the treatment of gynecomastia, and patients were satisfied with the results of our method. We concluded that XPS(R) microresector (Shaver) is an alternative option for the treatment of gynecomastia.

BACKGROUND: Idiopathic pulmonary fibrosis(IPF) is a fatal progressive fibrous disease of the lung of unknown etiology. Recently it has been classified into several distinct entities of the basis of pathologic and clinical characteristics, ie : usual interstitial pneumonia(UIP), desquamative interstitial pneumonia(DIP), acute interstitial pneumonia(AIP), bronchiolitis obliterans with organizing pneumonia(BOOP), and nonspecific interstitial pneumonia(NSIP). IPF is now applied only for UIP, which has the worst prognosis. The previous reports of 3-5 year median survival apears to be overoptimistic because other types with better prognosis like NSIP or BOOP might have been included. Therefore, this study was performed to determine the clinical course and the prognostic factors of UIP as diagnosed by surgical lung biopsy. METHODS: The subjects were 72 UIP patients (age 58.2±11.6 years, M:F=45:27, median follow up period:18.1 months (0.7-103.6) diagnosed by surgical lung biopsy at the Asan Medical Center (68 patients) and the Paik Hospital in Seoul (4 patients). Clinical scores (level of dyspnea:1-20 points), radiologic score (honey-combing : HC score 0-5 points, ground glass : GG score 0-5 points), and physiologic scores (FVC:1-12 points, FEV1:0-3 points, TLC:0-10 points, DDLC:0-5 points, AaDO2:0-10 points) were summed into a total CRP score. RESULTS: 1) The one year survival rate was 78.3%, while the rate for three year survival was 58.1%, and the median survival period was 42.5 months. 2) Short term (1 year) prognosis : The patients who died within one year of diagnosis (14 patients) had the higher initial total CRP score (28.6±8.3 vs. 16.6±9.7) than those who lived longer than one year (46 patients). The difference in the total CRP score was attributed to the symptom score (8.4±2.1 vs. 5.7±3.9) and the physiologic score (15.7±7.1 vs. 6.7±5.7) including FVC, DLCO, and AaDO2. 3) Long-term (3 year) prognosis : The total CRP score (12.2±6.7 vs. 28.7±7.9:including symptom score, FVC, DLCO, and AaDO2) at the time of diagnosis were also different for the long-term survivors and those who lived less than 3 years. 4) Cox regression analysis showed LCO (≥60%) (Hazard ratio:4.56, 95% CI:2.30-16.04) was the independent prognostic factors of UIP (P<0.05). CONCLUSION: These results suggest that DLCO at the time of diagnosis seem to be a prognostic markers of biopsy-proven UIP.

OBJECTIVES: Percutaneous renal biopsy may be carried out in several ways. Recently, the use of a spring-loaded biopsy gun has become popularized. There have been much controversies on the tissue adequacy and the incidence of complications when compared to the manual biopsy. The present study was performed to compare tissue adequacy and the incidence of complications between manual biopsy and automated biopsy. METHODS: We have studied 108 patients in whom the method of renal biopsy was assigned to one of the two methods[14G Tru-cut needle manual bx (group I) and 18G automated gun biopsy(group II)] according to their national resident's identification number in a randomized and prospective manner. RESULTS: There were 50 patients in group I and 58 patients in group II. There was no difference in gender, age, hemoglobin, prothrombin time, partial thromboplastin time, diastolic and systolic blood pressure pre-biopsy in group I and II. Indications for biopsies were proteinuria accompained by hematuria (37%), proteinuria(34.3%), acute renal failure (9.3%), SLE (8.3%), chronic renal failure (5.6%), hematuria only (5.6%). In Group I the number of passes was 2.4+/-0.8, the glomeruli obtained were 25.3+/-13.2 and the number of glomeruli per pass were 11.6+/-6.5, and in Group II 3.4+/-1.1, 19.4+/-10.8, and 6.8+/-4.0, respectively. These showed a significant difference (p<0.05). In all cases pathological diagnosis were possible. The histology showed IgA nephropathy in 27.8%, MCNS in 14.8%, lupus nephritis in 11.1, MGN in 11.1%, MPGN in 7.4%, and others. The incidence and area of perinephric hematoma demonstrated on ultrasound 24 hours post-biopsy was increased in group I (24%, 937.7+/-640.0mm2 compared to 10.3%, 372.4+/-327.4mm2 in group II) although no statistically significant difference existed. There was no significant difference in gender, age, prothrombin time, partial thromboplastin time, systolic and diastolic blood pressure between the group with and without hematomas. Hematocrit levels before and after biopsy showed a significant difference (34.5+/-8.2, 33.5+/-8.1, p<0.05) in group I, but no significant difference was observed in group II (34.7+/-6.4, 34.8+/-6.4). CONCLUSION: Both techniques rendered adequate tissue sampling, but the extent of bleeding seems to be more severe with manual 14G Tru-cut needle biopsy.

Angiotensin II (AngII) is a crucial hormone that affects vasoconstriction and exerts hypertrophic effects on vascular smooth muscle cells. Here, we showed that phosphatidylinositol 3-kinase-dependent calcium mobilization plays pivotal roles in AngII-induced vascular constriction. Stimulation of rat aortic vascular smooth muscle cell (RASMC)-embedded collagen gel with AngII rapidly induced contraction. AngII-induced collagen gel contraction was blocked by pretreatment with a phosphatidylinositol 3-kinase (PI3K) inhibitor (LY294002) whereas ERK inhibitor (PD98059) was not effective. AngII-induced collagen gel contraction was significantly blocked by extracellular calcium depletion by EGTA or by nifedipine which is an L-type calcium channel blocker. In addition, AngII-induced calcium mobilization was also blocked by nifedipine and EGTA, whereas intracellular calcium store-depletion by thapsigargin was not effective. Finally, pretreatment of rat aortic ring with LY294002 and nifedipine significantly reduced AngII-induced constriction. Given these results, we suggest that PI3K-dependent activation of L-type calcium channels might be involved in AngII-induced vascular constriction.

Crossed cerebellar diaschisis (CCD) is known to be due to a contralateral supratentorial lesion decreasing blood flow and the metabolism in a cerebellar hemisphere. Arterial spin labeling (ASL) is an imaging technique that utilizes arterial blood water as a tracer for quantifying the regional cerebral blood flow in magnetic resonance imaging (MRI). This case was a patient with simple partial status epilepticus (SPSE) and CCD confirmed by ASL-perfusion MRI. Controlling the SPSE resulted in improvement of CCD being observed in the follow-up ASL-perfusion MRI.

The purpose of this was to investigate the measurement of fluence dose map for the specific patient quality assurance. The measurement of fluence map was performed using 2D matrixx detector. The absorbed dose was measured by a glass detector, Gafchromic film and ion chamber in Hybrid Optimized VMAT Phantom (HOVP). For 2D Matrixx, the results of comparison were average passing rate 85.22%+/-1.7 (RT_Target), 89.96%+/-2.15 (LT_Target) and 95.14%+/-1.18 (G4). The dose difference was 11.72%+/-0.531, -11.47%+/-0.991, 7.81%+/-0.857, -4.14%+/-0.761 at the G1, G2, G3, G4. In HOVP, the results of comparison for film were average passing rate (3%, 3 mm) 93.64%+/-3.87, 90.82%+/-0.99. We were measured an absolute dose in steep gradient area G1, G2, G3, G4 using the glass detector. The difference between the measurement and calculation are 8.3% (G1), -5.4% (G2), 6.1% (G3), 7.2% (G4). The using an Ion-chamber were an average relative dose error -1.02%+/-0.222 (Rt_target), 0.96%+/-0.294 (Lt_target). Though we need a more study using a transmission detector. However, a measurement of real-time fluence map will be predicting a dose for real-time specific patient quality assurance in volume modulated arc therapy.

Akt plays pivotal roles in many physiological responses including growth, proliferation, survival, metabolism, and migration. In the current studies, we have evaluated the isoform-specific role of akt in lysophosphatidic acid (LPA)-induced cell migration. Ascites from ovarian cancer patients (AOCP) induced mouse embryo fibroblast (MEF) cell migration in a dose-dependent manner. On the other hand, ascites from liver cirrhosis patients (ALCP) did not induce MEF cell migration. AOCP-induced MEF cell migration was completely blocked by pre-treatment of cells with LPA receptor antagonist, Ki16425. Both LPA- and AOCP-induced MEF cell migration was completely attenuated by PI3K inhibitor, LY294002. Furthermore, cells lacking Akt1 displayed defect in LPA-induced cell migration. Re-expression of Akt1 in DKO (Akt1(-/-)Akt2(-/-)) cells restored LPA-induced cell migration, whereas re-expression of Akt2 in DKO cells could not restore the LPA-induced cell migration. Finally, Akt1 was selectively phosphorylated by LPA and AOCP stimulation. These results suggest that LPA is a major factor responsible for AOCP-induced cell migration and signaling specificity of Akt1 may dictate LPA-induced cell migration.

BACKGROUNDCentral blood pressure (BP) is pathophysiologically more important than peripheral BP for the pathogenesis of cardiovascular disease. Arterial stiffness is also a good predictor of cardiovascular morbidity and mortality. The effects of benidipine, a unique dual L-/T-type calcium channel blocker, on central BP have not been reported. This study aimed to compare the effect of benidipine and losartan on the central BP and arterial stiffness in mild to moderate essential hypertensives.
METHODSThis 24 weeks, multi-center, open label, randomized, active drug comparative, parallel group study was designed as a non-inferiority study. The eligible patients (n = 200) were randomly assigned to receive benidipine (n = 101) or losartan (n = 99). Radial artery applanation tonometry and pulse wave analysis were used to measure the central BP, pulse wave velocity (PWV) and augmentation index (AIx). We also measured the metabolic and inflammatory markers.
RESULTSAfter 24 weeks, the central BP decreased significantly from baseline by (16.8 ± 14.0/10.5 ± 9.2) mmHg (1 mmHg = 0.133 kPa) (systolic/diastolic BP; P < 0.001) in benidipine group and (18.9 ± 14.7/12.1 ± 10.2) mmHg (P < 0.001) in losartan group respectively. Both benidipine and losartan groups significantly lowered peripheral BP (P < 0.001) and AIx (P < 0.05), but there were no significant differences between the two groups. The mean aortic, brachial and femoral PWV did not change in both groups after 24-week treatment. There were no significant changes of the blood metabolic and inflammatory biomarkers in each group.
CONCLUSIONBenidipine is as effective as losartan in lowering the central and peripheral BP, and improving arterial stiffness.

Background:
Although international guidelines recommend palliative care approaches for many serious illnesses, the palliative needs of patients with serious illnesses other than cancer are often unmet, mainly due to insufficient prognosis-related discussion. We investigated physicians' and the general public's respective attitudes toward prognostic disclosure for several serious illnesses.
Methods:
We conducted a cross-sectional survey of 928 physicians, sourced from 12 hospitals and the Korean Medical Association, and 1,005 members of the general public, sourced from all 17 administrative divisions in Korea.
Results:
For most illnesses, most physicians (adjusted proportions – end-organ failure, 99.0%; incurable genetic or neurologic disease, 98.5%; acquired immune deficiency syndrome [AIDS], 98.4%; stroke or Parkinson's disease, 96.0%; and dementia, 89.6%) and members of the general public (end-organ failure, 92.0%; incurable genetic or neurologic disease, 92.5%; AIDS, 91.5%; stroke or Parkinson's disease, 92.1%; and dementia, 86.9%) wanted to be informed if they had a terminal prognosis. For physicians and the general public, the primary factor to consider when disclosing terminal status was “the patient's right to know his/her condition” (31.0%). Yet, the general public was less likely to prefer prognostic disclosure than physicians. Particularly, when their family members were patients, more than 10% of the general public did not want patients to be informed of their terminal prognosis. For the general public, the main reason for not disclosing prognosis was “psychological burden such as anxiety and depression” (35.8%), while for the physicians it was “disclosure would have no beneficial effect” (42.4%).
Conclusion
Most Physicians and the general public agreed that disclosure of a terminal prognosis respects patient autonomy for several serious illnesses. The low response rate of physicians might limit the generalizability of the results.
