Abstract
OBJECTIVES To measure left ventricular mass (LVM), left ventricular volumes, and left ventricular function (LVF) in a cohort of type 1 diabetic patients and to correlate measures of imaging to NH(2)-terminal pro-brain natriuretic peptide (NT-proBNP). RESEARCH DESIGN AND METHODS In a cross-sectional study, all patients with type 1 diabetes underwent cardiovascular magnetic resonance imaging. We included 63 patients with diabetic nephropathy and 73 patients with normoalbuminuria. RESULTS All patients had normal global LVF. LVM was increased in patients with diabetic nephropathy compared with patients with persistent normoalbuminuria. Patients with nephropathy had smaller left ventricular volumes and increased levels of NT-proBNP. Linear regression analysis in patients with diabetic nephropathy showed that NT-proBNP and creatinine were associated with LVM. CONCLUSIONS Increased LVM is identified in asymptomatic type 1 diabetic patients with nephropathy compared with normoalbuminuric patients. Elevated levels of NT-proBNP were associated with increased LVM, which are both markers of increased cardiovascular risk.

Abstract
Genetic variants of the organic cation transporter 2 (protein, OCT2; gene, SLC22A2) were evaluated for their contribution to the variations in the pharmacokinetics of metformin, especially to its renal elimination. Genetic variants of SLC22A2 (c.596C>T, c.602C>T, and c.808G>T) showed significant differences in metformin pharmacokinetics when compared with the reference genotype, with higher peak plasma concentration (C(max)) and area under the curve (AUC) and lower renal clearance (Cl(renal)), thereby suggesting that a decrease in transport function associated with the SLC22A2 variants results in reduced Cl(renal) of metformin and consequently leads to increased plasma concentrations.

Abstract
The aim of this retrospective study was to evaluate the clinical behavior and management outcome of low-grade endometrial stromal sarcoma (LGESS). From September 1994, to March 2007, 22 patients with histologically proven stage I LGESS were included in this study. Clinicopathologic variables, recurrence, and management outcomes were reviewed retrospectively. The median age of the 22 patients was 43 years. The most common presenting symptom was abnormal vaginal bleeding. All patients underwent a hysterectomy and had stage I disease. Six patients had adjuvant therapy after the hysterectomy. The median follow-up period was 77 months (range 12-202 months). Ten patients had disease recurrence. The median disease-free survival period was 111 months (range 6-182 months). The pelvis (eight cases) was the most common site of recurrence followed by the lung (four cases) and the liver (one case). Recurrent disease was treated with surgery (one case), surgery plus chemotherapy (five cases), chemotherapy (two cases), and surgery plus radiotherapy (two cases). Two patients died after 25 and 54 months after disease recurrence. Treatment with a bilateral salpingo-oophorectomy or adjuvant chemoradiation did not affect the disease-free interval. LGESS is usually a slow-growing neoplasm with an indolent clinical course. Surgery is the primary treatment for recurrent endometrial stromal sarcoma when feasible. Adjuvant treatment (radiotherapy, chemotherapy, or both) had no effect on the prognosis of patients with stage I disease.

Abstract
Brain metastasis from epithelial ovarian carcinoma (EOC) is managed by a multimodal treatment approach. Thus, to determine the prognostic factors associated with this situation is important for management decisions regarding the type of treatment and aggressiveness of treatment. From 1995 to 2005, 13 patients with brain metastases resulting from EOC underwent treatment at Samsung Medical Center. We retrospectively reviewed the medical records to determine prognostic factors and to evaluate treatment outcome. The median age at diagnosis for primary ovarian carcinoma and brain metastasis was 52 and 55 years, respectively. Median interval to brain metastases was 28 months after the diagnosis of EOC. At the time of analysis, nine patients had died of disease. The median survival from brain relapse was 7 months. A Karnofsky performance status of 70 or higher, primary control, solitary brain lesions, recursive partitioning analysis (RPA) class, and treatment modality including gamma-knife radiosurgery (GKRS) were related to survival on univariate analyses. Multivariate analysis showed that treatment modality including GKRS was a more important prognostic factor than RPA class (P= 0.04). This small series demonstrated that GKRS can be a valuable modality for the management of brain metastasis in patients with EOC. Therefore, a better outcome can be achieved by choosing GKRS in their treatments in selected patients.

Abstract
The purpose of this study was to determine whether Toll-like receptor 5 (TLR5) expression was associated with disease progression in cervical neoplasia. TLR5 expression was evaluated by immunohistochemistry (IHC) in 55 formalin-fixed paraffin-embedded cervical tissues; 10 normal cervical specimens, 9 low-grade cervical intraepithelial neoplasias (CINs), 12 high-grade CINs, and 24 invasive squamous cell carcinomas (ISCCs). TLR5 expression was also evaluated at the RNA level, in fresh, frozen cervical carcinoma tissues by real-time quantitative RT-PCR. TLR5 expression, which was mainly observed as cytoplasmic staining, gradually increased in accordance with the histopathologic grade in the following order: low-grade CIN less than high-grade CIN less than ISCC (P < 0.001). Immunohistochemical staining showed that TLR5 expression was undetectable (80%) or weak (20%) in normal cervical squamous epithelial tissues. However, moderate expression was detected in 33.3% of low-grade CIN (3/9), 41.7% of high-grade CIN (5/12), and 45.8% of ISCC (11/24). Strong expression was detected in as much as 33.3% of high-grade CIN (4/12) and 50% of ISCC (12/24). Contrary to IHC results, real-time quantitative RT-PCR revealed that TLR5 expression in tumors was not statistically different compared to normal cervical tissues (P = 0.1452). The IHC result suggests that TLR5 may play a significant role in tumor progression of cervical neoplasia and may represent a useful marker for malignant transformation of cervical squamous cells.

Abstract
INTRODUCTION Occupationally acquired hepatitis C viral infection is an important issue in surgery since there are no known vaccines or effective prophylaxis. MATERIALS AND METHODS An anonymous questionnaire survey was performed to determine the attitudes and perception of risks of occupational acquired hepatitis C viral transmission in orthopaedic surgeons. RESULTS A total of 763 questionnaires were posted to orthopaedic surgeons with various subspecialty interests and 261 surgeons responded (34.2%). Of respondents, 117 (47%) had sustained sharps injuries in the previous 12 months. Only 82 surgeons (33%) always reported such injuries, although 208 (84%) expressed concerns of occupationally acquired hepatitis C viral transmission. Orthopaedic surgeons were mostly unaware of the true prevalence of hepatitis C in high-risk groups, such as intravenous drug abusers. CONCLUSIONS Greater awareness of all aspects of hepatitis C infection and its risks to the practice of surgery is required. Further debate is necessary on the role of routine testing of surgeons and patients.

Abstract
INTRODUCTION Increasing subspecialisation, the introduction of reforms to surgical training, centralisation of hospitals and the reduction of working hours brought about by the European Working Time Directive (EWTD) has direct implications on the training of surgeons in the UK. The aim of this study was to determine the range and number of procedures performed for paediatric orthopaedic fractures, degree of supervision and possible implications for training. PATIENTS AND METHODS A retrospective review of procedures for paediatric orthopaedic fractures performed in a district general hospital in a year was conducted. RESULTS A total of 210 paediatric fracture procedures were performed, including 99 distal radius/ulna procedures, 28 shaft radius/ulna, 25 supracondylar procedures, 15 hand fracture procedures, 14 tibial shaft procedures. Middle grade/registrars and senior house officers performed 188 (89.5%) of all procedures. Consultant supervision was documented in 29 (13.8%) of all procedures performed. The number and type of common, as well as unusual, injuries was documented. The educational value of a training post may only be confirmed by reliable data which would provide an indication of operative opportunities and degree of supervision available to a trainee. CONCLUSIONS This study provided a model upon which all operative training opportunities in the orthopaedic department is documented. It is suggested that such data should form the basis of the establishment of training posts within a region. To maintain the high standard of orthopaedic training in the UK, the maintenance of such posts, number of trainees and seniority of trainees appointed to any hospital within a training region should be on the basis of data such as reported in this study.

Abstract
BACKGROUND Patients with type 1 diabetes and nephropathy maintain an excess cardiovascular mortality compared with diabetic patients with normoalbuminuria. We sought to evaluate coronary and aortic atherosclerosis in a cohort of asymptomatic type 1 diabetic patients with and without diabetic nephropathy using cardiovascular magnetic resonance imaging. METHODS AND RESULTS In a cross-sectional study, 136 subjects with long-standing type 1 diabetes without symptoms or history of cardiovascular disease, including 63 patients (46%) with nephropathy and 73 patients with normoalbuminuria, underwent cardiovascular magnetic resonance imaging. All subjects underwent cardiac exercise testing and noninvasive tests for peripheral artery disease and autonomic neuropathy. Coronary artery stenoses were identified in 10% of subjects with nephropathy (versus 0% with normoalbuminuria; P=0.007). Coronary plaque burden, expressed as right coronary artery mean wall thickness (1.7+/-0.3 versus 1.3+/-0.2 mm; P<0.001) and maximum right coronary artery wall thickness (2.2+/-0.5 versus 1.6+/-0.3 mm; P<0.001), was greater in subjects with nephropathy. The prevalence of thoracic (3% versus 0%; P=0.28) and abdominal aortic plaque (22% versus 16%; P=0.7) was similar in both groups. Subjects with and without abdominal aortic plaques had similar coronary plaque burden. CONCLUSIONS In asymptomatic type 1 diabetes, cardiovascular magnetic resonance imaging reveals greater coronary plaque burden in subjects with nephropathy compared with those with normoalbuminuria.

Abstract
Excessive acetabular cover secondary to a retroverted acetabulum causes pincer impingement, which may cause early osteoarthritis of the hip. Our aim was to determine if there was a relationship between acetabular version and osteoarthritis of the hip. Using image processing and analysis software we studied 117 CT images of the hip in patients aged less than 65 years who had undergone a CT virtual colonoscopy. The mean CT joint space of the 18 hips with acetabular retroversion was narrower compared with the 99 hips with normal acetabular alignment (p < 0.0001). A correlation of r = 0.46 (p < 0.01) was found between right hip acetabular version and the mean right hip joint space and of r = 0.31 (p = 0.02) between left hip acetabular version and the mean left hip joint space. Acetabular retroversion is associated with radiological evidence of osteoarthritis of the hip. An understanding of the mechanical basis of osteoarthritis of the hip allows early treatment of the underlying structural abnormality and prevents progression of the degenerative condition.

Abstract
OBJECTIVE The purpose of this study was to assess the prevalence of iron deficiency anemia among Korean pregnant women and to assess the association between maternal hemoglobin (Hb) level and pregnancy outcome. DESIGN A longitudinal study. SETTING Ewha Womans University Hospital, Seoul, Korea. SUBJECTS A total of 248 normal pregnant women of 24-28 weeks gestation and 190 babies born to the pregnant subjects. METHODS Maternal anthropometry, blood parameters and pregnancy outcomes were measured. RESULTS Mean Hb, serum iron concentration, transferrin saturation and total iron binding capacity of the subjects were 11.4 g/dl, 89.4 microg/dl, 18.7% and 484.6 microg/dl, respectively, and 30.2% of the subjects were anemic judged by Hb concentration of <10.5 g/dl. When subjects were classified into tertile groups based on Hb levels, the lowest tertile (HbT1) group had significantly lower concentrations of cord serum iron and albumin than those in the highest tertile (HbT3) group. Newborn infants from the HbT1 group had significantly higher rates of preterm delivery, low birth weight and low Apgar scores than those in other groups. Logistic regression analysis showed that maternal serum albumin and Hb level were the most important predictive variables for low birth weight. CONCLUSIONS A substantial proportion of Korean pregnant women were at risk of anemia. Infants born to women with a low Hb level showed a lower birth weight, height and Apgar scores.

Abstract
The ABG I uncemented hip prosthesis has demonstrated an unacceptably high failure rate and poor functional outcome in our patients. A prospective review was performed of 38 implanted hips with a mean follow-up of 11 years. Sixteen hips have been revised or are candidates for revision hip surgery, due principally to polyethylene wear and pelvic osteolysis. Contributing factors were likely to be the poor wear characteristics of the polyethylene liners--which were gamma irradiated in air--and the thinness of these liners. Of further concern were the poor pain and function scores in the remaining hips [mean Harris Hip Scores (HHS) of 70 (SD 22) at 11-year follow-up]. The influence of the surgical learning curve on clinical results may have been an important factor. Undersized femoral components were associated with poor pain and functional scores in five patients with HHS < 60. All ABG I hip implants must remain under careful, long-term review.

Abstract
AIMS We sought to evaluate the utility of contrast-enhanced coronary magnetic resonance imaging (CE-MRI) for selective visualization and non-invasive differentiation of atherosclerotic coronary plaque in humans. METHODS AND RESULTS Nine patients with coronary artery disease (CAD) as confirmed by X-ray angiography and multidetector computed tomography (MDCT) were studied by T1-weighted black blood inversion recovery coronary MRI before (N-IR) and after administration of Gd-DTPA (CE-IR). Plaques were categorized as calcified, non-calcified, and mixed based on their Hounsfield number derived from MDCT. With MDCT, a total of 29 plaques were identified, including calcified (n=6), non-calcified (n=6), and mixed calcified/non-calcified (n=17). On N-IR MRI, 26 plaques (90%) were dark, whereas three plaques (two non-calcified and one mixed) appeared bright. On CE-MRI, 13/29 (45%) plaques, 11 of which were mixed, one non-calcified, and one calcified showed contrast uptake. All others remained dark. CONCLUSION In this preliminary study, we demonstrate the potential utility of CE-IR MRI for selective plaque visualization and differentiation of plaque types. The observed contrast uptake may be associated with endothelial dysfunction, neovascularization, inflammation, and/or fibrosis.

Abstract
OBJECTIVE Mitral valve replacement with preservation of the entire subvalvular apparatus entails superior postoperative left ventricular function compared with other techniques. However, this option is often not possible because of valve pathology. We hypothesized that preservation of only 4 mitral valve secondary ("strut") chordae would be functionally and geometrically equivalent to total valve preservation in the long-term setting. In a porcine mitral valve replacement model we investigated the long-term effects of 3 surgical techniques on left ventricular function and geometry: (1) total preservation of the native valve, (2) strut chordal preservation, and (3) total excision of the subvalvular apparatus. METHODS Forty 60-kg pigs were randomized to 1 of the 3 techniques. Global and regional left ventricular function and dimensions were assessed with cardiovascular magnetic resonance and conductance catheter 90 days after mitral valve replacement. Groups were compared by multivariate analysis of variance. RESULTS There was no overall difference between groups 1 and 2. Group 3 animals had (1) greater base-apex diastolic and systolic lengths, and smaller short-axis diameters, and (2) lower sphericity indices, and greater base-apex and short-axis fractional shortening than groups 1 and 2. Regional analysis showed slimming and elongation to occur primarily in the basal left ventricular segments. Left ventricular contractility and hemodynamic parameters did not differ between groups. CONCLUSIONS Strut chordal preservation was equivalent to total valve preservation during mitral valve replacement, whereas total chordal resection caused significant left ventricular slimming with compensatory increases in fractional shortening. Therefore, to preserve left ventricular geometry, special attention must be paid to maintain the valvular-ventricular continuity through the strut chordae during mitral valve replacement. This concept may have important therapeutic implications for chordal-sparing mitral valve replacement.

Abstract
Routine removal of forearm plates in children remains controversial. The aim of the study was to assess if risks of complications associated with removal of forearm plates in children warrant routine removal of these plates. A total of 43 children (mean age 10.6 years old at time of fracture fixation) who had forearm plates removed after fracture fixation in our unit over a 10-year period were reviewed. There were three cases of re-fractures (two in the same child), all of which occurred following an episode of trauma and the use of Dynamic Compression Plates (DCP). One case of superficial infection was successfully treated with oral antibiotics. Low rates of complications from routine removal of metal work after forearm plating in children may be achieved.

Abstract
Congenital dislocation of the patella may be a phenotype, which has several genotypes, i.e. it may be congenital or acquired. This hypothesis is suggested with three illustrative case studies. Risk factors predictive of the development of irreducible dislocation of the patella in infancy are suggested. As there is a spectrum of possible aetiologies, 'late' diagnosis and a number of 'risk' factors but a common pathology, the word 'congenital' is not always appropriate. We suggest 'Developmental dysplasia and dislocation of the patella (DDDP)' is a more appropriate term for this rare condition.

Abstract
A randomised controlled trial was performed in 50 patients with acute isolated minimally displaced lesser metatarsal fractures in order to compare plaster immobilisation with elasticated support bandage treatment. Patients treated with elasticated support bandage had significantly higher AOFAS mid-foot scores at 3-months follow-up and complained of less pain throughout the treatment period. There was no difference between the two groups in time to independent mobility, mid-foot circumference, analgesic requirements and radiological union at 3 months. As plaster casts are associated with serious complications, which were encountered in these studies, we conclude that minimally displaced metatarsal fractures are better treated without a cast.

Abstract
The severity of symptoms in osteoarthritis (OA) of the knee can be difficult to assess. A new method for assessing medial compartment OA of the knee is proposed. The purpose of this study was to determine if a relationship exists between the severity of OA and single limb stance knee adduction moment (SSKAM). Fourteen patients with medial compartment OA of the knee were tested and compared with 14 age-matched volunteers. WOMAC OA index scores were documented. Biomechanical data were collected from a single Kistler force platform and a six-camera ProReflex motion analysis system, and the knee adduction moments were calculated. A significant difference in the maximum, minimum and mean adduction moments was found between the two groups, and a correlation of r=0.66 for WOMAC physical function subscale, r=0.63 for the WOMAC pain subscale and r=0.63 for the sum of the subscales and mean SSKAM was found. Single limb stance adduction moments provide additional, objective information in the assessment of medial compartment OA of the knee. It may be useful in the selection of patients for surgery and for evaluating various treatment modalities for medial compartment OA of the knee.

Abstract
Many procedures have been described for the correction of congenital dislocation of the patella. Most operations entail extensive soft tissue releases through curved skin incisions. A modification of the Langenskiold and Ritsila procedure is described. The main alterations include a limited and straight anterior skin incision, a fashioning of a 'buckle' of the transferred distal-patellar tendon to a distally based flap and the transposition of an extensive medial rotation flap. This report describes the early results (mean=19 months) of the modified procedure in three cases of congenital lateral dislocation of the patella.
