Abstract
PURPOSE To evaluate the efficacy and safety of switching from adalimumab originator (Humira, AbbVie) to SB5, adalimumab biosimilar (Adalloce, Samsung Bioepis) in patients with noninfectious uveitis (NIU). METHODS Fifteen patients (29 eyes) with NIU who were switched from adalimumab originator to SB5 and followed up for 6 months or longer were retrospectively included. Data consisted of best-corrected visual acuity (BCVA, logMAR), intraocular pressure (IOP, mmHg), anterior chamber (AC) cell grade, anterior vitreous (AV) cell grade, vitreous haze grade, central macular thickness (CMT, μm), and macular volume (MV, mm3) at pre-switching, 2, 4, and 6 months post-switching. RESULTS There were no significant differences in BCVA, AC and AV cell grades, and vitreous haze grades at 2, 4, and 6 months post- compared with pre-switching, and no significant differences in CMT and MV at 2 and 6 months post-switching. CMT and MV decreased from 260.55 ± 67.44 μm and 8.37 ± 1.14 mm3 at pre-switching to 244.14 ± 60.31 μm (p = 0.032) and 8.11 ± 1.20 mm3 (p = 0.027) at 4 months post-switching, respectively. There was no recurrence of uveitis, as defined by AC cell grade, vitreous haze, or BCVA. Four patients (27%) were switched back to adalimumab originator after a mean of 9 weeks, due to discomfort during the injection (three patients) and technical difficulty with the new injection device (one patient). No other adverse events occurred after switching to SB5. CONCLUSION Switching from adalimumab originator to SB5 for NIU does not result in clinically significant differences in treatment efficacy and safety.

Abstract
PURPOSE The aim of the present report wasto describe a novel technique of robotic abdominoperineal resection (APR) for the treatment of T4b low rectal cancer using the da Vinci® Single-Port (SP) system (Intuitive Surgical, Sunnyvale, CA, USA). METHODS A 3-cm transverse incision was made in the left lower quadrant of the abdomen, in the area designated for permanent colostomy. A Uniport® (Dalim Medical, Seoul, Korea) was introduced and a 25 mm multichannel SP trocar was inserted into the Uniport. A 5-mm laparoscopic assistant port was introduced on the upper midline. A video showing each step of the technique is attached. RESULTS Two consecutive female patients (70 and 74 years old) underwent SP robotic APR with partial resection of the vagina 8 weeks after preoperative chemoradiotherapy. In both cases, rectal cancer was located 1 cm above the anal verge and invaded the vagina (initial stage and ymrT stage T4b). Operative time was 150 and 180 min, respectively. Estimated blood loss was 10 and 25 ml, respectively. No postoperative complications occurred. The length of postoperative hospital stay was 5 days in both cases. The final pathological stage was ypT4bN0 and ypT3N0 respectively. CONCLUSIONS In this first experience, SP robotic APR appears to be a safe and feasible procedure for locally advanced low rectal cancer. In addition, the invasiveness of the procedure is reduced by means of the SP system, which only requires a single incision in the area designated for colostomy. Prospective studies on a larger number of patients are necessary to confirm the outcomes of this technique compared to other minimally invasive approaches.

Abstract
UNLABELLED Several patients with chronic kidney disease (CKD) have deteriorated bone status. Estimation of bone status using DXA has limitations especially in patients with CKD accompanying aortic calcifications. Quantitative CT and the trabecular bone score could be more accurate methods to estimate bone status for patients with CKD and vascular calcifications. INTRODUCTION It remains unclear whether dual-energy absorptiometry (DXA) is appropriate for the assessment of bone status in patients with chronic kidney disease (CKD), a disease that impacts bone health. The aims of this study were to compare DXA and central quantitative computed tomography (cQCT) and to evaluate bone status in patients with pre-dialysis CKD. METHODS This retrospective study included 363 healthy control subjects whose bone mineral density (BMD) was evaluated with DXA and 117 CKD patients whose BMD was evaluated using both cQCT and DXA. Diagnostic discordance was assessed between the lumbar spine (LS) and femur neck (FN) from DXA or between two modalities. The trabecular bone score (TBS) was extracted from DXA images. The volume of abdominal aortic calcification (AAC) was calculated using CT images from cQCT. RESULTS Using LS DXA T-score, osteoporosis was less common in the CKD group than in controls. Patients with normal LS BMD using DXA were reclassified into osteopenia or osteoporosis using cQCT in CKD patients. Among discordant subjects between FN and LS in DXA, a higher BMD of LS was more common in CKD patients than in controls. CKD patients had lower TBS than controls despite having the same diagnosis using DXA. AAC volume negatively correlated with BMD from cQCT and with TBS but not with BMD from DXA. CONCLUSIONS TBS and cQCT could accurately assess bone status in CKD patients since DXA may overestimate LS BMD, likely due to an increased AAC volume.

Abstract
BACKGROUND The da Vinci single-port (SP) system is designed to facilitate single-incision robotic surgery in a narrow space. We developed a new procedure of rectal resection using this system. The aim of the present study was to evaluate the technical feasibility and safety of SP robotic rectal resection for rectal cancer patients based on our initial experience. METHODS A study was conducted on consecutive patients with mid or low rectal cancer who had SP robotic resection at our institution between July and September 2020. The demographic characteristics, perioperative data, and pathology results of the patients were retrospectively analyzed. RESULTS There were 5 patients (3 males, 2 females, median age 57 years (range 36-73 years). The median tumor height from the anal verge was 4 cm (range 3-5 cm). Two patients received preoperative chemoradiotherapy for advanced rectal cancer. A single docking was conducted, and the median docking time was 4 min 20 s (range 3 min 30 s to 5 min). The median total operation time was 195 min (range 155-240 min), and the median time of pelvic dissection was 45 min (range 36-62 min). All patients had circumferential and distal tumor-free resection margins. One patient experienced an anastomosis-related complication. The median duration of hospital stay was 7 days (range 7-8 days). CONCLUSIONS Our initial experience suggests that SP robotic rectal resection is safe and feasible. Further clinical trials comparing SP and multiport robotic rectal resection should be conducted to verify the superior aspects of this new system.

Abstract
OBJECTIVE To investigate the disease progression and immunoprotective characteristics in mice re-infected with homogeneous/heterogeneous Plasmodium strains following cure of Plasmodium infections with chloroquine at the peak of parasitemia. METHODS C57BL/6 mice were infected with the non-lethal P. yoelii 17XNL strain, and half of mice were given treatment with chloroquine at the peak of parasitemia (9 days post-infection), while the other mice were self-cured naturally. Then, all cured mice were re-infected with the equivalent lethal P. yoelii 17XL or P. berghei ANKA strain 90 days following primary Plasmodium infections. The parasitemia levels during primary infections and reinfections were measured by microscopic examinations of Giemsa-stained thin blood films, and the levels of the IgG antibody in sera and the percentages of memory T cell subsets in spleen cells were detected in mice using ELISA and flow cytometry before and after parasite reinfections, respectively. RESULTS Following primary infections with the P. yoelii 17XNL strain, the serum IgG antibody levels were (5.047 ± 0.924) pg/mL in the selfcured mice and (4.429 ± 0.624) pg/mL in the chloroquine-treated mice, respectively (t = 0.437, P > 0.05), which were both significantly higher than that in the uninfected mice (1.624 pg/mL ± 0.280 pg/mL) (F = 22.522, P < 0.01). There was no significant difference in the serum IgG antibody level among self-cured and chloroquine-treated mice re-infected with the P. yoelii 17XL strain or the P. berghei ANKA strain (F = 0.542, P > 0.05); however, the serum IgG antibody levels were all significantly higher in selfcured and chloroquine-treated mice re-infected with the P. yoelii 17XLstrain[(15.487±1.173)pg/mLand(15.965±1.150)pg/mL] or the P. berghei ANKA strain [(14.644 ± 1.523) pg/mL and (15.185 ± 1.333) pg/mL] relative to primary infections (F = 67.383, P < 0.01). There was no significant difference in the proportion of CD4+ [(34.208 ± 2.106), (32.820 ± 1.930), (34.023 ± 2.289), (35.608 ± 1.779) pg/mL] or CD8+ T memory cells [(17.935 ± 2.092), (18.918 ± 2.823), (17.103 ± 1.627), (17.873 ± 1.425) pg/mL] in self-cured and chloroquine-treated mice with primary infections with the P. yoelii 17XNL strain followed by re-infections with the P. yoelii 17XL strain or the P. berghei ANKA strain (F = 0.944 and 0.390, both P > 0.05); however, the proportions of the CD4+ or CD8+ T memory cells were significantly greater in self-cured and chloroquine-treated mice with primary infections with the P. yoelii 17XNL strain followed by re-infections with the P. yoelii 17XL strain or the P. berghei ANKA strain than in mice with primary infections (F = 50.532 and 21.751, both P < 0.01). CONCLUSIONS The cure of murine Plasmodium infections with chloroquine does not affect the production of effective immune protections in mice during parasite re-infections. Following a primary infection, mice show a protection against re-infections with either homogeneous or heterogeneous Plasmodium strains, and a higher-level resistance to re-infections with homogeneous parasite strains is found than with heterogeneous strains.

Abstract
A leading cause of traumatic brain injury (TBI) is intracranial brain deformation due to mechanical impact. This deformation is viscoelastic and differs from a traditional rigid transformation. In this paper, we describe a machine learning enabled wireless sensing system that predicts the trajectory of intracranial brain deformation. The sensing system consists of an implantable soft magnet and an external magnetic sensor array with a sensing volume of 12 × 12 × 4 mm3. Machine learning algorithm predicts the brain deformation by interpreting the magnetic sensor outputs created by the change in position of the implanted soft magnet. Three different machine learning models were trained on calibration data: (1) random forests, (2) k-nearest neighbors, and (3) a multi-layer perceptron-based neural network. These models were validated using both in vitro (a needle inserted into PVC gel) and in vivo (blast exposure to live and dead rat brains) experiments. The in vitro gel deformation predicted by these machine learning models showed excellent agreement with the camera measurements and had absolute error = 138 μm, Fréchet distance = 372 μm with normalized Procrustes disparity = 0.034. The in vivo brain deformation predicted by these models had absolute error = 50 μm, Fréchet distance = 95 μm with normalized Procrustes disparity = 0.055 for dead animal and absolute error = 125 μm, Fréchet distance = 289 μm with normalized Procrustes disparity = 0.2 for live animal respectively. These results suggest that the proposed machine learning enabled sensor system can be an effective tool for measuring in situ brain deformation.

Abstract
Purpose To investigate the effect of 0.1% bromfenac sodium hydrate ophthalmic solution for prevention of macular edema after cataract surgery in patients with diabetes. Methods A retrospective analysis of 75 patients with diabetes who underwent cataract surgery was performed. Thirty-eight patients (52 eyes) were instilled with 0.1% bromfenac solution (bromfenac group) and 37 patients (46 eyes) were not (control group). Results There were no significant preoperative between-group differences. Compared to the control group, at 1 month after surgery, the bromfenac group showed slightly better best-corrected visual acuity (0.12 ± 0.12 vs. 0.32 ± 0.42, p = 0.142), lower central macular thickness (265.58 ± 31.28 vs. 314.15 ± 76.11 µm, p < 0.001), and lower macular volume (8.46 ± 0.60 vs. 9.14 ± 1.53 mm3, p = 0.022). There were no significant differences between the two groups at 4 and 6 months postoperatively (p > 0.05). Mean changes in central macular thickness showed significant differences at 1 and 4 months postoperatively (−1.44 ± 11.72 and 10.44 ± 22.48 µm in bromfenac group vs. 47.19 ± 70.24 and 31.69 ± 48.04 µm in control group, p < 0.001 and p = 0.016) and mean changes in macular volume showed a significant difference at 1 month postoperatively (−0.08 ± 0.47 mm3 in bromfenac group vs. 0.58 ± 1.28 mm3 in control group, p < 0.001). There were no significant differences thereafter (p > 0.05). Conclusions Treatment with 0.1% bromfenac sodium hydrate ophthalmic solution showed good efficacy for preventing cystoid macular edema early after cataract surgery in patients with diabetes.

Abstract
Electrolytic ablation (EA) is a promising nonthermal tumor ablation technique that destroys malignant cells through induction of a locoregional pH change. EA is typically performed by inserting needle electrodes inside the tumor followed by application of direct current (DC), thus inducing electrolysis and creating localized pH changes around the electrodes. In this paper, we report an ultrasonically powered implantable EA microprobe that may increase the clinical relevance of EA by allowing wireless control over device operation (capability to remotely turn the device on and off) and providing flexibility in treatment options (easier to administer fractionated doses over a longer period). The wireless EA microprobe consists of a millimeter-sized piezoelectric ultrasonic receiver, a rectifier circuit, and a pair of platinum electrodes (overall size is 9 × 3 × 2 mm3). Once implanted through a minimally invasive procedure, the microprobe can stay within a solid tumor and be repeatedly used as needed. Ultrasonic power allows for efficient power delivery to mm-scale devices implanted deep within soft tissues of the body. The microprobe is capable of producing a direct current of 90 µA at a voltage of 5 V across the electrodes under low-intensity ultrasound (~200 mW/cm2). The DC power creates acidic (pH < 2) and alkaline (pH > 12.9) regions around the anode and the cathode, respectively. The pH change, measured using tissue-mimicking agarose gel, extends to 0.8 cm3 in volume within an hour at an expansion rate of 0.5 mm3/min. The microprobe-mediated EA ablative capability is demonstrated in vitro in cancer cells and ex vivo in mouse liver.

Abstract
Abstract
Background
Accurate reports of occupational injuries are important to monitor workplace safety and health initiatives. In South Korea, media reports, experts, and workers have been constantly raising the issue of underreporting. Supposedly it is because employers have strong market “incentives” by underreporting their employees’ injuries. A critical way to underreport or cover-up is illegal compensation (in Korean called “gong-sang”). Unfortunately, “gong-sang” is not counted as official occupational injury statistics. The aim of this study was to analyze the social media data using topic modeling and to explore issues surrounding “gong-sang”.
Methods
We used web scraping technology and collected 2,210 social media data from Web search engines. Data was processed to transform unstructured textual documents into structured data using the Python and applied Latent Dirichlet allocation (LDA) in the Python library, Gensim, for topic modeling.
Results
Based on the LDA method from “gong-sang”- related documentation, 10 topics were identified. Topic 1 was the greatest concern (60.5%), with keywords implying the choice between illegal compensation (“gong-sang”) and legal insurance claims. The next concern was Topic 2 including keywords associated with claims for industrial accident insurance benefits. The rest topics (topic 3-10) showed the monetary issue, precarious employment, and vulnerable body parts to “gong-sang”.
Conclusions
We explored web-based data and identified the salient issues surrounding “gong-sang”. LDA topics may be helpful to ensure efficient occupational health and safety scheme to protect vulnerable employees from “gong-sang” practices.
Key messages
The topics formulated by LDA included queries about legal insurance claims. Legal insurance claims including private or social insurance, monetary compensation, injured body parts, and the type of jobs vulnerable to “gong-sang”.

Abstract
INTRODUCTION Penile length is an important indicator of male sexual development. Scarce data were reported on penile length measurements in children comparing changes between prepuberty and puberty for the small penile issue with long-term follow-up. OBJECTIVE The purpose of this study was to investigate the possibility of catch-up growth of the penile length of boys with a small penis in the long-term follow-up. STUDY DESIGN From April 2001 to December 2016, 27 boys who visited the outpatient clinic owing to a small penis, without any chromosomal anomalies and other genital disorder, were investigated retrospectively. Micropenis is defined as 2.5 standard deviations less than the mean stretched penile length (SPL) of age. Periodic penile length, testicular volume, hormonal levels (serum testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH)), and bone age were measured. Pubertal development was recorded by using the Tanner scale. The effect of hormonal therapy and the factors attributable to the increment of the penile length were evaluated. RESULTS The mean age at the first visit was 9.8 years (5-12 years) and that at puberty was 12.6 years (10-16 years). The length of the penis at the initial visit was 4.0 ± 0.8 cm (2.5-6.0) and at puberty, 7.3 ± 1.8 cm (4.0-12.0). Nine patients diagnosed with micropenis no longer had a micropenis in puberty. The less the age-matched SPL, the more the increment of SPL that was observed (rho = - 0.548, P = 0.003). The mean increment of SPL in the hormonal therapy group (11 boys) and the non-hormonal therapy group (16 boys) was not statistically different (43.5 ± 22. 9% vs 41.5 ± 21.6%, respectively, P = 0.497). DISCUSSION This study explains how much the growth of a small penis catches up in puberty. From the point of view of the increment of SPL, the increment was higher in boys who belonged to the smaller penis group. Hormonal therapy does not attribute to an increase in the length after long-term follow-up. Limitations of this study were its retrospective origin with a small number of patients in a single center. CONCLUSION Catch-up growth of the small penis at puberty was accomplished in most children with a small penis before puberty. Hormonal treatment was not significantly correlated with the penile length increment in the long-term follow-up.

Abstract
Abstract
Background
In patients with early stage breast cancer, regional nodal irradiation (RNI) is added to whole breast irradiation (WBI) in order to control microscopic regional disease and to prevent systemic spread of cancer. According to recent randomized trials (MA.20 and EORTC 22922-10925), prophylactic RNI was associated with improvement in disease-free survival (DFS) in the patients with high-risk node negative or pN1 breast cancer. However, systemic agents now known to improve loco-regional control, such as taxane or endocrine therapy, were prescribed to a small percentage of patients in the studies. The benefit of RNI found in the previous studies might be attributed to incorporation of less effective systemic treatments. The impact of prophylactic RNI in pN1 breast cancer should be evaluated in the patients receiving modern systemic treatment. The current study was conducted to compare the effect of post-lumpectomy WBI vs WBI plus RNI on DFS in pN1 breast cancer patients who received adjuvant taxane-based chemotherapy.
Methods
This study is a multicenter, phase 3, randomized controlled non-inferiority trial (NCT03269981). Eligibility criteria are ≥ 20 years female; pathologically proven invasive carcinoma of the breast; one to three positive axillary lymph nodes (pN1) in pathologic specimen; receiving breast-conserving surgery followed by taxane-based chemotherapy; having adjuvant endocrine therapy or anti-HER2 treatment according to molecular subtype of tumor. Patients are randomly assigned in a 1:1 ratio to receive WBI or WBI plus RNI. Patient randomization was stratified by molecular subtype of tumor (i.e. luminal A/luminal B/luminal HER2/HER2-enriched/triple-negative) and methods of axillary management (i.e. sentinel lymph node biopsy/axillary lymph node dissection). The primary outcome is DFS. The secondary outcomes include DFS according to molecular subtype, treatment-related toxicity, and patient's quality of life per EORTC QLQ-C30 and QLQ-BR23. Patients will be followed for survival and disease recurrence for seven years. A total of 1,926 patients are planned to be enrolled, with recruitment initiated in April 2017. As of June 2018, a total of 236 patients were enrolled.

Abstract
BACKGROUND To analyze our initial results of hand-assisted laparoscopic living donor nephrectomy, executed by a skilled gastrointestinal surgeon. METHODS A total of 22 consecutive patients underwent the hand-assisted laparoscopic living donor nephrectomy between December 2014 and January 2017. We retrospectively analyze the patient's perioperative clinical data, which were collected prospectively. RESULTS The right kidney was harvested in 12 patients. The mean operative time and intraoperative blood loss was 241.0 ± 43.4 minutes (range, 140-310 min) and 293.2 ± 203.1 mL (range, 50-700 mL), respectively. The mean warm ischemic time was 288.4 ± 103.4 seconds (range, 179-610 s). Postoperative complications included chyle leakage in 2 patients who were left kidney donors and oliguria in 1 patient who was a right kidney donor. All patients recovered with conservative care, and the mean hospital stay was 7.5 ± 1.7 days. The mean creatinine level was 0.7 ± 0.2 mg/dL before surgery, 1.1 ± 0.3 mg/dL at postoperative day (POD) 1, and 1.0 ± 0.2 mg/dL after discharge. The mean glomerular filtration rate was 97.9 ± 18.2 mL/min/1.73 m2 before surgery, 60.7 ± 10.4 at POD 1, and 67.3 ± 11.1 after discharge. Operation time was not associated with patient body mass index and case number. No significant differences, other than postoperative complications, were found in the perioperative data for the side of kidney donation. CONCLUSION A skilled surgeon with experience in laparoscopic abdominal surgery (such as gastrectomy or colectomy) might safely perform hand-assisted donor nephrectomy. However, we could not identify a clear case number to complete the learning curve.

Abstract
Kidney transplant recipients are at increased risk of cardiovascular morbidity and malignant neoplasm, and meticulous evaluation of potential recipients is needed to minimize risks of complications after transplantation. The purpose of this study was to analyze the results of preoperative assessments and document the importance of timed and detailed examinations. METHODS Medical records of patients evaluated as kidney transplant candidates from January 2015 to September 2017 were retrospectively collected and analyzed. RESULTS Of the 216 patients evaluated during the study period, 135 (62.5%) were male, 112 (51.9%) had diabetes mellitus, 163 (75.5%) had hypertension, 31 (14.4%) had a cardiovascular event history, and 7 (3.2%) had previous history of malignant neoplasms. Mean (SD) patient age was 50.7 (10.8) years. All 216 recipient candidates underwent echocardiography. Mean (SD) ejection fraction was 57.8% (5.9%), and 48 candidates (22.2%) showed regional wall motional abnormality. Coronary angiography was performed on 81 candidates, and in 57 (70.4%) of these, coronary artery disease was detected. Malignant neoplasms were detected in 10 (4.6%) candidates. Kidney transplantation was performed on 55 candidates. One recipient died of Pneumocystis jirovecii pneumonia at 15 months after kidney transplant, but there was no death-censored graft failure, newly detected malignant neoplasm, or cardiovascular event over a mean (SD) follow-up duration of 15.5 (8.6) months. CONCLUSION Evaluation of kidney transplant candidates resulted in diagnoses of malignant neoplasms in 4.6% of patients and coronary artery disease in 26.4% of patients. The results of this study demonstrate candidates for kidney transplant should undergo detailed preoperative evaluation.

Abstract
BACKGROUND The shortage of donor organs has been a major challenge in transplantation. In an effort to reduce the donor shortage, kidney transplantation (KT) using expanded criteria donors (ECD) was encouraged. In Korea, transplantation centers used the Korea Network for Organ Sharing (KONOS) ECD criteria, which is different from the United Network for Organ Sharing (UNOS) criteria. The aim of this study is to evaluate the predictive power of KONOS criteria on delayed graft function (DGF) in comparison to UNOS criteria. METHODS A total of 376 recipients who underwent deceased donor kidney transplantation between January 2005 and December 2014 at Severance Hospital were retrospectively reviewed. Of these, 130 cases satisfied KONOS ECD, while the others followed KONOS standard criteria donor (SCD). RESULTS Donor age and history of hypertension was significantly higher with KONOS ECD than with KONOS SCD. In KONOS subgroup analysis, donor characteristics were different than with UNOS criteria. The incidence of DGF was higher in the KONOS ECD group than in the KONOS SCD group. However, UNOS ECD showed a high incidence of DGF compared to UNOS SCD with the same KONOS criteria. UNOS ECD was an independent risk factor for DGF in multivariate analysis. However, KONOS ECD was not a risk factor for DGF. Although glomerular filtration rate was inferior in the KONOS ECD group compared to the KONOS SCD group, the UNOS SCD group within the KONOS ECD group showed similar graft function compared to the KONOS SCD group. CONCLUSION KONOS criteria have a lower predictive power for DGF than UNOS criteria.

Abstract
Sirolimus (SRL), a mammalian target of rapamycin inhibitor, is widely used in transplantation, but the mechanisms whereby it induces adverse effects, such as proteinuria and edema, remain unclear. To determine whether isolated SRL induces proteinuria or not, the authors intraperitoneally injected C57BL/6 mice with different doses of SRL (0 mg/[kg·d], 3 mg/[kg·d], 10 mg/[kg·d], or 30 mg/[kg·d]) for 24 days. Urinary albumin excretion was then quantified using a double-sandwich enzyme-linked immunosorbent assay, and serum creatinine levels were measured using a single dry-film chemistry auto-analyzer. The mRNA expression levels of various genes were also measured by polymerase chain reaction. Urinary albumin was not detected in the SRL-treated mice, but serum creatinine levels were found to increase dose-dependently and were significantly higher in the animals treated with 30 mg/kg of SRL than in untreated controls. Glomerular mRNA expression profiling showed down-regulations of podocyte-related genes (Wilms tumor 1, synaptopodin, nephrin, CD2-associated protein, and podocin) and of transforming growth factor-beta (a marker of fibrosis) in sirolimus-treated mice. In addition, expressions of the antiapoptotic genes Bcl-2 and Bcl-xL were also down-regulated. Furthermore, the protein levels of these genes in mice kidney were also decreased by sirolimus. Although sirolimus treatment reduced the expressions of slit diaphragm-associated molecules and increased serum creatinine levels, it failed to induce proteinuria. Our findings indicate that proteinuria is not induced by isolated SRL treatment. Further studies are required to identify conditions in which sirolimus induces proteinuria.

Abstract
OBJECTIVE Little is known about the burden of severe retinal disease between young-onset type 2 (T2D) and type 1 diabetes (T1D). This study assessed the prevalence of significant retinopathy in young-onset T2D vs. T1D and its predictive factors. METHODS This was a cross-sectional study. Subjects with T1D and T2D diagnosed below age 40 were identified from diabetes eye screening register. Preproliferative, proliferative, maculopathy changes and/or previous laser photocoagulation treatment were considered to have significant retinopathy (SigDR). RESULTS A total of 1306 subjects were identified, of whom 842 and 464 had T1D and T2D, respectively. The mean age of diagnosis was significantly lower in T1D subjects (T1D vs. T2D; 20.1 ± 10.3 vs. 32.1 ± 6.0 years, p < 0.0005). Although the T2D cohort had shorter diabetes duration (T1D vs. T2D; 20.8 ± 13.0 vs. 13.7 ± 9.0 years, p < 0.0005), the overall prevalence of SigDR was similar to T1D (T1D vs. T2D; 21.6 vs. 20.9%, p = NS). After adjusting for diabetes duration, the T2D cohort experienced significantly higher prevalence of this complication than T1D after 10 years duration. The age threshold beyond which the T2D cohort began to experience greater burden of SigDR was approximately 50 years. The prevalence of any retinopathy after 15 years duration was 75-80% for both young-onset cohort. Risk factors for SigDR (older age, diabetes duration, systolic BP, HbA1c and creatinine) were similar in both young-onset diabetes cohort with poor glycaemic control being the strongest variable. Lower age of T2D diagnosis was not a predictive factor. CONCLUSIONS Irrespective of diabetes type, subjects with young-onset diabetes possessed high lifetime risk for retinopathy. However, young-onset T2D cohort was more susceptible to severe retinal disease with substantial burden of this complication by the fifth decade of life.

Abstract
Recent meta-analysis by the Cochrane collaboration concluded that treatment of varicocele may improve an infertile couple's chance of pregnancy. However, there has been no consensus on the management of subclinical varicocele. Therefore, we determine the impact of varicocele treatment on semen parameters and pregnancy rate in men with subclinical varicocele. The randomised controlled trials that assessed the presence and/or treatment of subclinical varicocele were included for systematic review and meta-analysis. Random effect model was used to calculate the weighted mean difference of semen parameters and odds ratio of pregnancy rates. Seven trials with 548 participants, 276 in subclinical varicocelectomy and 272 in no-treatment or clomiphene citrate subjects, were included. Although there was also no statistically significant difference in pregnancy rate (OR 1.29, 95% CI 0.99-1.67), surgical treatment resulted in statistically significant improvements on forward progressive sperm motility (MD 3.94, 95% CI 1.24-6.65). However, the evidence is not enough to allow final conclusions because the quality of included studies is very low and further research is needed.

Abstract
The CCCTC-binding factor (CTCF)/cohesin complex regulates gene transcription via high-order chromatin organization of the genome. De novo methylation of CpG islands in the promoter region is an epigenetic hallmark of gene silencing in cancer. Although the CTCF/cohesin complex preferentially targets hypomethylated DNA, it remains unclear whether the CTCF/cohesin-mediated high-order chromatin structure is affected by DNA methylation during tumorigenesis. We found that DNA methylation downregulates the expression of prostaglandin-endoperoxide synthase 2 (PTGS2), which is an inducible, rate-limiting enzyme for prostaglandin synthesis, by disrupting CTCF/cohesin-mediated chromatin looping. We show that the CTCF/cohesin complex is enriched near a CpG island associated with PTGS2 and that the PTGS2 locus forms chromatin loops through methylation-sensitive binding of the CTCF/cohesin complex. DNA methylation abolishes the association of the CTCF/cohesin complex with the PTGS2 CpG island. Disruption of chromatin looping by DNA methylation abrogates the enrichment of transcriptional components, such as positive elongation factor b, at the transcriptional start site of the PTGS2 locus. These alterations result in the downregulation of PTGS2. Our results provide evidence that CTCF/cohesin-mediated chromatin looping of the PTGS2 locus is dynamically influenced by the DNA methylation status.

Abstract
BACKGROUND "Flat-line" (no clot formation) thromboelastography (TEG) is frequently observed after graft reperfusion during liver transplantation (LT). We aimed to evaluate the incidence and causes of flat-line TEG after graft reperfusion during LT. METHODS With institutional review board approval, data of 208 consecutive recipients who underwent LT from May 2010 to May 2012 were retrospectively reviewed. We performed 3 different types of TEG measurements at 5 minutes after graft reperfusion: native TEG (nTEG), tranexamic acid-added TEG (tTEG), and protamine-added TEG (pTEG). The flat-line TEG was defined as having no trace at all at 60 minutes of TEG. We examined the incidence and causes of flat-line nTEG. We also compared recipients with flat-line nTEG (F group) and clot-forming nTEG (C group). RESULTS One hundred eighty-two recipients were included in the final analysis. The incidence of flat-line nTEG was 27% (49/182 cases). Among 49 recipients in the F group, 28 recipients showed clot formation in both tTEG and pTEG, 19 recipients in only tTEG, and 1 recipient in only pTEG; 1 recipient showed no clot formation in any TEGs. Graft from the deceased donor was more frequently observed in the F group than in the C group (P = .039). The F group showed decreased platelet count (P = .001), increased prothrombin time (P = .002), and decreased fibrinogen (P = .009) compared with the C group. CONCLUSIONS No clot formation was relatively common after reperfusion during LT, and the main causes were hyperfibrinolysis and heparin effect. Liver graft from deceased donors was associated more frequently with no clot formation after reperfusion during LT.

Abstract
In addition to superior energy-conversion efficiency at millimeter-scale dimensions, ultrasonic wireless powering offers deeper penetration depth and omnidirectionality as compared to the traditional inductive powering method. This makes ultrasound an attractive candidate for powering deep-seated implantable medical devices. In this paper, we investigate ultrasonic powering of millimeter-scale devices with specific emphasize on the output power levels, efficiency, range, and omnidirectionality. Piezoelectric receivers 1 ×5 ×1 mm(3), 2 ×2 ×2 mm(3), and 2 ×4 ×2 mm(3) in size are able to generate 2.48, 8.7, and 12.0 mW of electrical power, while irradiated at 1.15 and 2.3 MHz within FDA limits for medical imaging (peak acoustic intensity of 720 mW/cm(2)). The receivers have corresponding efficiencies of 0.4%, 1.7%, and 2.7%, respectively, at 20-cm powering distance. Due to the form factor and reflections from tissue-air boundaries, the output power stays constant to within 92% when the angular positions of the transmitter and receiver are varied around a cylindrical shell.

Abstract
BACKGROUND The currently available treatments for warts, including cryosurgery, laser surgery, electrosurgery, and topical keratolytic applications, are often very painful and can induce disfiguring scars. Recently, intralesional immunotherapy with skin test antigens and vaccines has been shown to be effective in the management of warts. AIMS To evaluate the efficacy of a new intralesional immunotherapy for warts, using the measles, mumps and rubella (MMR) vaccine. METHODS A retrospective study was performed, and we enrolled 136 patients with various types of warts into the study, which was for a duration of 2 years. Patients were treated for a total of six times at 2-week intervals. The treatment response was classified as one of three levels, based on reduction in the size and number of warts, and patients with complete response (CR) were checked for recurrence. Clinical evaluations were carried out using photographs and medical records. RESULTS Over half (51.5%) of patients experienced > 50% reduction in the size and number of warts, and 46.7% who had distant warts (in different locations) showed good response. Common warts showed significantly higher treatment response than other types of warts (P < 0.05). However, other clinical variables did not have any effect on efficacy. Almost all the patients reported mild pain during the injection, but other side effects were rarely observed. Only 5.6% of patients who experienced CR had recurrence of warts after 6 months. CONCLUSIONS We suggest that intralesional immunotherapy with MMR vaccine is a tolerable and effective method for patients who are sensitive to pain, concerned about side effects, or have common warts. Treatment response is improved by increasing the number of injections.

Abstract
PURPOSE This study aimed to analyze the clinical features of lumbar hernia reported in South Korea and compare these features with those reported in foreign literature. METHODS From January 1968 through December 2013, 13 cases reported in South Korea were included in the study. The variables compared were age, sex, main symptoms at hospital visit, etiology, location, herniated contents, lateralization, defect size, diagnostic methods, surgical methods, surgical opinions, and recurrence. RESULTS In the South Korean cases, women outnumbered men (3.3:1) and no significant differences were found in the herniated side (left:right, 1.1:1). In contrast, in the foreign cases, men outnumbered women (3:1) and left-sided hernia was dominant (2:1). Moreover, in most of the foreign cases, patients were aged 50-70 years, whereas in the South Korean cases, none of the patients were in their 50 s. However, no substantial differences were found in etiology, anatomical locations, symptoms, and herniated contents. CONCLUSION This research revealed that few clinical features of lumbar hernias in South Korea differ from those reported in foreign literature. Thirteen cases were analyzed in the present study, and results obtained from such a small sample size cannot be generalized with certainty. Therefore, more cases should be collected for a definitive analysis. Despite this limitation, this study is important because it is the first attempt to collect and analyze the clinical features of lumbar hernia in South Korea. This study will serve as a basis for future studies investigating the clinical features of lumbar hernia cases in South Korea.

Abstract
Adipokines, adipocyte-derived protein, have important roles in various kinds of physiology including energy homeostasis. Chemerin, one of adipocyte-derived adipokines, is highly expressed in differentiated adipocytes and is known to induce macrophage chemotaxis and glucose intolerance. The objective of the present study was to investigate the changes of chemerin and the chemokine-like-receptor 1 (CMKLR1) gene expression levels during differentiation of the bovine adipocyte and in differentiated adipocytes treated with tumor necrosis factor-α (TNF-α), adiponectin, leptin, and chemerin (peptide analog). The expression levels of the chemerin gene increased at d 6 and 12 of the differentiation period accompanied by increased cytoplasm lipid droplets. From d 6 onward, peroxisome proliferator-activated receptor-γ2 (PPAR-γ2) gene expression levels were significantly higher than that of d 0 and 3. In contrast, CMKLR1 expression levels decreased at the end of the differentiation period. In fully differentiated adipocytes (i.e. at d 12), the treatment of TNF-α and adiponectin upregulated both chemerin and CMKLR1 gene expression levels, although leptin did not show such effects. Moreover, chemerin analog treatment was shown to upregulate chemerin gene expression levels regardless of doses. These results suggest that the expression of chemerin in bovine adipocyte might be regulated by chemerin itself and other adipokines, which indicates its possible role in modulating the adipokine secretions in adipose tissues.

Abstract
OBJECTIVE To investigate the effectiveness of laparoscopic varicocelectomy (LV) in adolescents with varicocele and analyze the impact of internal spermatic artery (ISA) preservation on surgical outcomes. MATERIALS AND METHODS Data on 92 adolescents with left varicocele who underwent LV between December 1998 and January 2011 were retrospectively analyzed. The mean age of the patients was 13.2 ± 2.1 years. Age, grade of disease, number of ligation veins, recurrence rates, and catch-up growth were analyzed in patients who underwent ISA preservation and ligation. The median duration of the follow-up was 21 months. RESULTS ISA preservation was performed on 50 patients (54%). There were no significant inter-group differences in terms of age, varicocele grade, number of ligation veins, and catch-up growth (93% vs. 90%). The patients who received artery preservation demonstrated a higher recurrence rate (22%) than those who received artery ligation (5%; p = 0.032). Among 13 patients who had persistent or recurrent varicocele, nine were treated with embolization and one was treated with magnification-assisted subinguinal varicocelectomy. None of these 10 patients demonstrated recurrence or testicular atrophy. CONCLUSIONS LV with ISA ligation can reduce the recurrence rate and results in the same catch-up growth rate in comparison with LV with ISA preservation.

Abstract
The aim of this study is to evaluate the results of gradual ulnar correction and lengthening using the modified Ilizarov technique for the treatment of forearm deformities in patients with multiple cartilaginous exostoses. We retrospectively reviewed 23 forearms in 16 patients. Three different types of operative procedures were performed: (1) corrective osteotomy and gradual lengthening of the ulna, (2) corrective osteotomy of the radius, and (3) excision of exostoses. We evaluated the radiographs; range of motion of the wrist, forearm, and elbow; and functional status using a questionnaire before and after operation. During the clinical interview, post-operative functional status was significantly improved than pre-operative functional status, 12 patients stated that they had no difficulty in performing daily activities, 11 patients stated that they had no pain, and 11 patients stated that the post-operative appearance of the operated forearm was satisfactory. At time of final follow-up, the mean range of motion of the wrist in ulnar/radial deviation, forearm pronation/supination was significantly improved. Also, the radiographic parameters including radial articular angle, carpal slip, radial bowing, and ulnar variance were significantly improved at time of final follow-up. In conclusion, we achieved successful clinical and radiological outcomes in our patients with forearm deformities after treatment with the modified Ilizarov method. However, there could be a recurrence of ulnar shortening and deformity during growth periods in skeletally immature patients.

Abstract
AIMS To determine the burden of atherogenic apolipoprotein particles in early-onset type 2 diabetes (T2D) compared to those with later-onset disease during statin treatment. METHODS Early and later-onset T2D was defined as current age below and above 40 years respectively. Conventional lipid profile, LDL, non-HDL cholesterol, apolipoprotein B and A1 were determined in those without cardiovascular disease treated with simvastatin to achieve LDL cholesterol <2 mmol/l. RESULTS Fifty subjects were recruited (early-onset n=24 and later-onset n=26). The mean age was 34.5 and 59.6 years and mean age of diagnosis was 29.1 and 49.1 years for early and later-onset T2D respectively. Obesity, dyslipidaemia, microalbuminuria, glycaemic control and diabetes complication burden were similar in both cohorts. Early-onset subjects received non-significantly higher simvastatin dose (37.5 vs. 31.9 mg daily, p=NS). On-treatment LDL cholesterol was similar in both cohorts (early vs. later-onset; 2.12 vs. 1.97 mmol/l, p=NS). Fasting triglyceride, non-HDL, apo B and B/A1 ratio were significantly higher in early-onset cohort. There was no difference in apo A1, HDL and total cholesterol/HDL ratio. Apo B level remained significantly higher among early-onset subjects after adjustment for insulin treatment. Lower current age and age of diagnosis were significant predictors of higher apo B level. CONCLUSION The burden of atherogenic apolipoprotein particles was greater in early-onset T2D despite adequate statin treatment indicating an adverse phenotype for vascular disease.

Abstract
INTRODUCTION Anatomic variants of the hepatic vasculature are common, so precise preoperative donor evaluation, including variations in the vasculature, is essential. We analyzed the anatomic similarity according to the donor-recipient relationship. METHODS Among the cases who underwent living donor liver transplantations from September 2008 to January 2011 we selected 104 cases with clearly defined hepatic artery and portal vein on preoperative computed tomography. They were classified according to Hiatt et al for the hepatic artery and Cheng for the portal vein. We categorized the 104 cases into three groups: parents-child (n=40), sibling (n=24) and no-relation (n=40), for analysis of the concordance of the hepatic artery and portal vein. RESULT Anatomic variations were observed in 25% of donors and 23.1% of recipients in the hepatic artery and 6.7% of donors and 10.6% of recipients in the portal vein. There was no significant difference in the distribution of the type of hepatic vasculature. Identical anatomic variations between donors and recipients were observed in 62.5% of the parent-child; 66.7% of the sibling and 52.5% of no-related group (P=.493) in the hepatic artery and 92.5%, 100%, and 77.5% (P=.014) in the portal vein respectively. CONCLUSION There was no similarity in the anatomic variations of the hepatic artery according to the donor-recipient relationship, but a similarity in portal venous anatomy according to the donor-recipient relationship.

Abstract
PURPOSE Proteinuria in the nontransplant population is a progressive renal disease. We analyzed the prevalence and clinical significance of proteinuria as well as factors related to its degree at posttransplant year 1 among kidney transplant recipients. METHODS We measured protein in a 24-hour urine among 644 recipients from January 1996 to December 2010. RESULTS Among 372 male and 272 female recipients, the mean amount of urinary protein was 424.4 ± 1010 mg/d (range, 13.88-8691) including 388 (60.2%) subjects with microproteinuria and the other 256 (39.8%) with overt proteinuria. Nephrotic range proteinuria was observed in 17 (2.6%) and nonnephritic range proteinuria, in 239 (37.1%) recipients. The latter cohort was categorized into low-grade proteinuria (n = 224; 34.8%) and high-grade proteinuria (n = 15; 2.3%). Proteinuria at posttransplant 1 year highly correlated with serum creatinine values at posttransplant years 1 and 2 as well as estimated glomerular filtration rate but not creatinine clearance at postoperative year 2. A greater incidence of graft loss was observed among recipients with more severe proteinuria. Males, recipients with anti-hepatitis C virus antibody, unrelated donors, anti-thymocyte immunoglobulin at the time of reperfusion, maintenance immunosuppression with cyclosporine or without mycophenolate mofetil were strongly associated with the amount of proteinuria. CONCLUSION This study demonstrated the prevalence of proteinuria in kidney transplant recipient to be high. The presence as well as level of proteinuria were predictive markers for inferior allograft function.

Abstract
This study evaluated the effect of limb lengthening on longitudinal growth in patients with achondroplasia. Growth of the lower extremity was assessed retrospectively by serial radiographs in 35 skeletally immature patients with achondroplasia who underwent bilateral limb lengthening (Group 1), and in 12 skeletally immature patients with achondroplasia who did not (Group 2). In Group 1, 23 patients underwent only tibial lengthening (Group 1a) and 12 patients underwent tibial and femoral lengthening sequentially (Group 1b). The mean lengthening in the tibia was 9.2 cm (59.5%) in Group 1a, and 9.0 cm (58.2%) in the tibia and 10.2 cm (54.3%) in the femur in Group 1b. The mean follow-up was 9.3 years (8.6 to 10.3). The final mean total length of lower extremity in Group 1a was 526.6 mm (501.3 to 552.9) at the time of skeletal maturity and 610.1 mm (577.6 to 638.6) in Group 1b, compared with 457.0 mm (411.7 to 502.3) in Group 2. However, the mean actual length, representing the length solely grown from the physis without the length of distraction, showed that there was a significant disturbance of growth after limb lengthening. In Group 1a, a mean decrease of 22.4 mm (21.3 to 23.1) (4.9%) was observed in the actual limb length when compared with Group 2, and a greater mean decrease of 38.9 mm (37.2 to 40.8) (8.5%) was observed in Group 1b when compared with Group 2 at skeletal maturity. In Group 1, the mean actual limb length was 16.5 mm (15.8 to 17.2) (3.6%) shorter in Group 1b when compared with Group 1a at the time of skeletal maturity. Premature physeal closure was seen mostly in the proximal tibia and the distal femur with relative preservation of proximal femur and distal tibia. We suggest that significant disturbance of growth can occur after extensive limb lengthening in patients with achondroplasia, and therefore, this should be included in pre-operative counselling of these patients and their parents.

Abstract
OBJECTIVE: This study aimed to identify factors that predict clearance of high-risk human papillomavirus (HPV) infection and progression to cervical intraepithelial neoplasia (CIN) 2 or higher, in women with normal cervical histology or CIN 1. METHODS: A retrospective analysis was performed on 817 high-risk HPV-infected women with histologically verified CIN 1 or normal cervical histology. Patients were followed-up for a maximum of 24 months. Cervical HPV DNA tests were performed at every visit. RESULTS: At the end of follow-up, 648/817 (79.3%) patients were free from HPV infection and 66/817 patients (8.1%) progressed to CIN 2 or higher. Age, parity, cytology and viral load at diagnosis were significantly and inversely associated with HPV clearance. Cytology, viral load and presence of CIN 1 lesions were significantly associated with lesion progression. CONCLUSIONS: Cytology and high-risk HPV viral load may be useful markers for the likelihood of high-risk HPV clearance and lesion progression. Histological status, parity and marital status may also be useful factors to consider when predicting progression.

Abstract
PURPOSE Alemtuzumab (Campath-1H), a humanized monoclonal antibody directed against CD52, is a lymphocyte-depleting agent currently being evaluated as an induction agent in solid organ transplantation. This study analyzed the clinical outcomes and effects on peripheral blood lymphocyte subset counts in adult deceased donor renal transplant recipients who received an alemtuzumab-based induction protocol. METHODS Eleven kidney alone or simultaneous pancreas-kidney transplant recipients received 20 mg alemtuzumab on postoperative days 0 and 1, followed by calcineurin inhibitor-based maintenance immunosuppression after postoperative day 5. We collected 1-year data including recipient and donor demographic features, renal function and adverse events including endocrine impact, incidence of acute rejection episodes, infections or malignancies as well as hematologic and late immunologic parameters for correlation with patient or graft survival. RESULTS Mean HLA mismatch was 3.6 and 8/11 deceased donors were of the extended criteria type. Only 2 (18%) recipients displayed delayed graft function with a failure of the serum creatinine to decrease by 25% on the first day; however, their long-term outcomes were similar to other nonaffected patients. Serious adverse events were absent; there was no hyperlipidemia or new-onset diabetes. We failed to observe an acute rejection. The 3 (27%) recipients with infectious complications experienced pericardial tuberculosis, urinary tract infection, or invasive pulmonary aspergillosis. Two (18%) cases of posttransplantation lymphoproliferative disease were diagnosed in this study during the follow-up. Overall patient and graft survival rates were both 91%. CONCLUSION This study demonstrated that preconditioning with antibody-depletion using alemtuzumab was efficient with satisfactory patient and graft survivals at 1 year. Alemtuzumab induction was safe even for recipients of extended criteria donor renal transplantation.

Abstract
Mesenchymal stem cells (MSCs) are progenitors that are capable of differentiating into mesenchymal tissues. They are known to support allogeneic hematopoietic stem cell transplantation by facilitating engraftment without increasing the risk of graft-versus-host disease. We optimized culture conditions for human fetal liver-derived MSCs (hFL-MSCs) to investigate the role of hFL-MSCs on repopulation of hematopoietic stem cells in NOD/Shi-scid/IL-2Rγ(null) (NOG) mice using CD34(+) hematopoietic stem cells (HSCs) derived from umbilical cord blood (UCB). FL-MSCs and CD34(+) HSCs were prepared from fetal liver and UCB, respectively. Twenty-four hours after irradiation, CD34(+) HSCs and hFL-MSCs were injected intravenously and intratibially into NOG mice. During 24 weeks posttransplantation, engraftment levels of human cells were analyzed in bone marrow, peripheral blood, and spleen of transplanted mice by flow cytometry. hFL-MSCs showed a fibroblast-like morphology and immunophenotypic characteristics appropriate for MSCs. hFL-MSCs prolonged the survival of NOG mice that had been cotransplanted with UCB CD34(+) cells. Fluorescence-activated cell-sorting analysis showed that engraftment of human cells was increased by cotransplantation of hFL-MSCs. However, significant enhancement of human cell engraftment was not detected in NOG mice regardless of the number of cotransplanted MSCs. Although survival of repopulating NOG mice and engraftment of human cells were prolonged by cotransplantation of hFL-MSCs, 8.0 × 10(6) MSCs were not sufficient to increase HSC engraftment in irradiated NOG mice in vivo.

Abstract
BACKGROUND The mechanism of cyclosporine (CsA)-induced nephrotoxicity has been suggested to be vasoconstriction due to reduced nitric oxide (NO), providing tissue fibrosis by elevation of transforming growth factor beta and vascular endothelial growth factor (VEGF). In this study using a rat model of CsA-induced nephrotoxicity, we administered a phosphodiesterase-5 inhibitor to ameliorate the renal injury and alter the expression of endothelial No synthase (eNOS) and VEGF. METHODS A right nephrectomy was performed in Sprague-Dawley rats (n = 30; 200-250 g, all male). The Ischemia group (n = 6) underwent ligation of the left renal artery for 45 minutes (IR) before observation for 28 days. After IR, the udenafil group (n = 6) was treated with 10 mg/kg drug orally, the CsA group (n = 6) received 15 mg/kg CsA injected subcutaneously and the CsA plus udenafil group (n = 6) received 15 mg/kg CsA injected subcutaneously together with the oral administration of 10 mg/kg udenafil. RESULTS Administration of udenafil significantly decreased serum creatinine either alone (0.21 ± 0.04 mg/dL) or in combination with CsA (1.86 ± 0.35 mg/dL) versus the ischemia (0.85 ± 0.22 mg/dL) and the CsA alone (3. 10 ± 0.77 mg/dL) group. (P = .002; P = .002). Comparing the Hematoxylin-eosin staining of the ischemia (0.41 ± 0.09) and CsA (0.44 ± 0.08) groups showed a significantly decreased loss of nuclei in proximal tubules after the administration of udenafil (0.27 ± 0.05 [P = .004] and 0.26 ± 0.02 [P = .002] respectively). Immunohistochemical staining showed strong eNOS staining in the udenafil and CsA plus udenafil groups. Western blots for eNOS showed decreased expression in the CsA group and increased expression in the udenafil group. Western blots for VEGF revealed reduced expression only in the CsA plus udenafil group. eNOS mRNA was decreased in the CsA (0.017 ± 0.010) compared with the ischemia group (0.048 ± 0.015; P = .000). VEGF mRNA which was decreased in the CsA group (2.026 ± 1.109), showed greater tendency after administration of udenafil (0.440 ± 0.449) (P = .003). CONCLUSION The phosphodiesterase inhibitor ameliorated renal injury in a rat model of CsA-induced nephrotoxicity, possibly related to increased eNOS and reduced VEGF expression.

Abstract
Mammalian target of rapamycin complex (mTORC) regulates a variety of cellular responses including proliferation, growth, differentiation and cell migration. In this study, we show that mammalian target of rapamycin complex 2 (mTORC2) regulates invasive cancer cell migration through selective activation of Akt1. Insulin-like growth factor-1 (IGF-1)-induced SKOV-3 cell migration was completely abolished by phosphatidylinositol 3-kinase (PI3K) (LY294002, 10 μM) or Akt inhibitors (SH-5, 50 μM), whereas inhibition of extracellular-regulated kinase by an ERK inhibitor (PD98059, 10 μM) or inhibition of mammalian target of rapamycin complex 1 (mTORC1) by an mTORC1 inhibitor (Rapamycin, 100 nM) did not affect IGF-1-induced SKOV-3 cell migration. Inactivation of mTORC2 by silencing Rapamycin-insensitive companion of mTOR (Rictor), abolished IGF-1-induced SKOV-3 cell migration as well as activation of Akt. However, inactivation of mTORC1 by silencing of Raptor had no effect. Silencing of Akt1 but not Akt2 attenuated IGF-1-induced SKOV-3 cell migration. Rictor was preferentially associated with Akt1 rather than Akt2, and over-expression of Rictor facilitated IGF-1-induced Akt1 activation. Expression of PIP3-dependent Rac exchanger1 (P-Rex1), a Rac guanosine exchange factor and a component of the mTOR complex, strongly stimulated activation of Akt1. Furthermore, knockdown of P-Rex1 attenuated Akt activation as well as IGF-1-induced SKOV-3 cell migration. Silencing of Akt1 or P-Rex1 abolished IGF-1-induced SKOV-3 cell invasion. Finally, silencing of Akt1 blocked in vivo metastasis, whereas silencing of Akt2 did not. Given these results, we suggest that selective activation of Akt1 through mTORC2 and P-Rex1 regulates cancer cell migration, invasion and metastasis.

Abstract
BACKGROUND 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) adds to conventional imaging in the detection and staging of peritoneal carcinomatosis. CASE REPORT Herein we report a 27-year-old woman with multiple intraperitoneal masses detected by 18F-FDG-PET, suggesting peritoneal carcinomatosis. She had undergone laparoscopic unilateral oophorectomy for a left ovarian mucinous borderline tumor approximately five years before. Based on imaging and intraoperative findings, multiple intraabdominal masses strongly suggested peritoneal recurrence from a previous ovarian borderline tumor, but it finally proved to be inflammation and fibrosis on histopathologic examination. CONCLUSION Although 18F-FDG-PET is well known to be a highly sensitive imaging tool for identification of peritoneal carcinomatosis, FDG uptake is not tumor-specific. Therefore, the possibility of a false-positive diagnosis due to benign conditions, such as inflammation, should always be taken into consideration.

Abstract
BACKGROUND The incidence of bone metastasis is low in metastatic cervical cancer, especially in the case of adenocarcinoma. Incidental finding of a mass located in an unusual metastatic site in the absence of identifiable primary tumor often results in a difficult diagnostic problem. CASE REPORT We report the case of a 59-year-old woman presenting left-sided foot drop as her initial symptom. At first, after performing lumbar spine magnetic resonance imaging (MRI), a huge paravertebral mass with ipsilateral psoas muscle involvement suggesting retroperitoneal sarcoma was identified. However, cervical punch biopsy and sono-guided paravertebral mass biopsy revealed cervical adenocarcinoma with lumbar spinal metastasis. CONCLUSION Although rare, a neurological symptom such as foot drop, not vaginal symptoms, in a woman may be a first manifestation of metastatic cervical cancer, especially in spinal metastasis. Furthermore, any abnormal lesion should not be ignored because of the possibility of metastasis from the primary malignancy, especially in the current case of cervical adenocarcinoma, so a complete evaluation is always mandatory.

Abstract
Primary serous papillary carcinoma of the peritoneum is a rare tumor, histologically similar to primary ovarian carcinoma. Pelvic CT and MRI are helpful to diagnose primary carcinoma of the peritoneum. We present a case of primary serous carcinoma of the peritoneum mimicking pelvic actinomycosis in a 59-year-old woman. Pelvic CT and MRI suggested pelvic actinomycosis. Exploratory laparotomy was performed to remove the mass and the diagnosis was confirmed by pathology. A subtotal hysterectomy, left salpingo-oophorectomy and omentectomy were performed. Histopathology examination revealed peritoneal carcinomatosis and primary serous carcinoma of the peritoneum. Pelvic CT and MRI were limited in their ability to differentiate inflammation, such as actinomycosis, from primary carcinoma of the peritoneum.

Abstract
BACKGROUND Little is known about the complication burden in later years among early onset type 2 diabetes mellitus (T2DM). AIM To determine the magnitude of diabetes complications and adequacy of risk factor management and to test the hypothesis that diabetes duration is an important contributing factor to these complications. DESIGN A cross-sectional study of secondary care diabetes population. METHODS Data on glycaemic control, cardiovascular risk factors (overweight/obesity, hypertension, dyslipidaemia), cardiovascular disease (CVD) and microvascular complications among those diagnosed before (early onset) and after (later onset) 40 years of age at different diabetes durations (<10, 10-20 and >20 years) were analysed. RESULTS A total of 2733 subjects were identified, of which 527 had diabetes diagnosed below the age of 40 years. By the sixth decade of life, early onset cohort experienced high complication burden (CVD: 37.2%, retinopathy: 59.3% and neuropathy: 53.1%). Complication prevalence increased with diabetes duration but the increment rate was greater among early onset cohort. Compared with those diagnosed after 40, early onset cohort experienced similar burden of microvascular complications approximately 13-20 years earlier. Diabetes duration was a significant predictor for microvascular and CVD complications. Prevalence of CVD risk factors was high ( approximately 80-93%) regardless of the age of diagnosis and diabetes duration. Early onset subjects were more likely to have poorer glucose control ( approximately 70-78%), untreated hypertension (26.3%) and a substantial number did not receive statin treatment for primary prevention (34.8%). DISCUSSION Early onset T2DM subjects are at substantial risk of developing diabetes complications in later years but at an earlier stage than later onset cohort and prolonged exposure to adverse diabetic milieu is an important contributing factor. Management of risk factors for diabetes complications was inadequate among early onset subjects.
