Abstract
AIM In comparison to round breast implants, anatomically formed implants have a broader indication spectrum in augmentation surgery for the formation of a natural breast shape. In order to achieve a long-term result, it is necessary for anatomically formed breast implants to remain secured in the position desired and planned initially. In the case of textured implants of a certain pore size and depth, this can be aided by the development of a stabilising implant-capsule-interaction (interface). The aim of this study was to investigate whether there are sonographic criteria for verifying the position of anatomically formed breast implants and the development of a stable interface. MATERIAL AND METHODS 628 patients underwent breast implant surgery and were followed up clinically as well as sonographically at the Frauenklinik und Institut für Asthetische Chirugie am St. Josefs-Hospital, Wiesbaden. 228 implants (Style 410 Inamed McGhain) were evaluated after a mean of 27 months postoperatively. Only cosmetic augmentations were included in the results. Verification of the implant position was conducted by palpation as well as by sonography. Statistical analysis was performed using the McNemar-Test (Chi-squared test). RESULTS Two marker points on the anterior side of the implant capsule in the lower hemisphere, which are designed for intraoperative position monitoring by palpation, could be reproduced sonographically in all cases and the position of the breast implant could thereby by determined. Two cases of clinically apparent implant rotation of more than 90 degrees around the vertical axis were discovered in this way. The sonographical identification of the development of a stable interface between the implant and the periprosthetic capsule is possible when sonographic criteria of the "parasternal movement layer" are met. The sonographic outcome is significantly superior to palpation. CONCLUSION Breast sonography used for the clinical follow-up of patients with anatomically formed breast implants represents an efficient diagnostic supplement with clinical relevance.

Abstract
We describe and discuss the design of a variable-temperature scanning tunneling microscope (STM) system for the study of molecules at temperatures between 18 and 300 K in ultrahigh vacuum. The STM head is a refinement of a very rigid design developed and successfully operated in Hamburg. In the current version, the head is connected to a liquid helium flow cryostat, thereby reaching a base temperature of 18 K. To minimize the heat load on the STM head, a helium back flow cooled radiation shield is installed. The dimensions and the choice of materials are based on simulations of the heat dissipation. The STM is galvanically isolated from the vacuum chamber to minimize electronic noise and mechanically decoupled by means of springs and an eddy current damping stage. Additionally, the design of the STM head allows the deposition of several molecular materials onto the same cold sample surface. The operation of the STM in imaging mode is demonstrated for TPP/Cu(111) and FePCNaClCu(111). Spectroscopic capabilities of the system are shown for electronic states on NaClCu(111) and TPP/Cu(111).

Abstract
BACKGROUND In recent years multi-resistant pathogens, particularly methicillin-resistant Staphylococcus aureus (MRSA) have been causing increasing problems in hospitals and nursing homes. In Germany area-wide and interdisciplinary studies of prevalence of MRSA have not previously been conducted. For this reason we investigated the its prevalence in a cross-sectional study, which included patients in hospitals, rehabilitation centers and nursing homes in a rural district in Germany. METHODS AND PATIENTS The MRSA prevalence was determined by obtaining cultures from the nose, throat and any existing skin lesions of each patient in medical institutions and nursing homes in the the Höxter district. The presence of methicillin resistance, Panton-Valentine leukocidin (PVL) gene were determined and and staphylococcal protein A (spa) typing was done. Potential risk factors for MRSA colonization were also determined. RESULTS S. aureus was isolated from 319 of 1 083 patients (614 females, 469 males; median age 68,2 years) from five hospitals, five nursing homes und three rehabilitation centers. The MRSA prevalence was 2,5% (95% confidence interval (CI) 1,7-3,7%). In hospitals the MRSA prevalence was 3,4%, in the nursing homes 2,3% and in rehabilitation centers 1,2%, without any significant difference between these three establishments. The proportion of MRSA in all S. aureus isolates was 8,5%. The PVL gene was not detected. It was found by multivariate analysis that variables independently associated with evidence of MRSA were haemodialysis (odds ratio (OR) 11,2; 95% CI 1,9-67,4) and an acute infection in the six months before hospital admission (OR 6,5; 95% CI 1,5-29,2). The spa typing showed different regional distribution of the MRSA subtypes. With 30% the spa type t003 (ST225 clone; in Germany called "Rhine-Hessen strain") occurred most frequently, followed by t032 with 22,2% (ST22 clone, also called "Barnimer strain"). CONCLUSIONS This first regional cross-sectional study provides supportive data for MRSA surveillance in Germany and the data provide a basis for additional preventative measures.

Abstract
A high-resolution deuterium profile is now available along the entire European Project for Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine isotope stage 20.2, approximately 800,000 years ago. Experiments performed with an atmospheric general circulation model including water isotopes support its temperature interpretation. We assessed the general correspondence between Dansgaard-Oeschger events and their smoothed Antarctic counterparts for this Dome C record, which reveals the presence of such features with similar amplitudes during previous glacial periods. We suggest that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.

Abstract
STUDY DESIGN Prospective control cohort study. OBJECTIVES To develop a new test to analyse qualitatively grasping strategies in C6/C7 tetraplegic patients, and to quantify the effect of musculo-tendinous transfers. SETTING France. METHODS Twelve C6/C7 tetraplegic adults (17 arms; 31.3+/-7.9 years) and 17 healthy subjects (30.9+/-9.4 years) completed the study. We assessed participants' ability to grasp, move and release standardized balls of variable sizes and weights. OUTCOME MEASURES Failures, movement duration (MD), grip patterns, forearm orientation during transport. RESULTS In patients as well as in controls, the number of digits involved in prehension increased proportionally to the size and weight of the ball. C6 non-operated tetraplegic patients failed 38.2% of the tasks. They frequently used supine transport (51.4% of successful tasks). MD was longer, with a large distribution of values. The presence of active elbow extension poorly influenced the amount of failure nor grip configuration, but significantly reduced MD and supine transport (34%). Patients who were evaluated after hand surgery showed a trend towards improved MD and more frequent completion (failure 30%), especially for middle-sized and middle-weighted balls. Grip patterns were deeply modified, and all transports were made in pronation. CONCLUSION The 'Tetra Ball Test' evidences the characteristics of grasping in tetraplegic patients and those influenced by surgery. It may be useful in understanding effects of surgical procedures. This preliminary study must be completed to evaluate the quantitative responsiveness and reproducibility of this test and to develop instrumented electronic balls to optimise it.

Abstract
BACKGROUND No three-dimensional (3-D) data exist on the influence of motion velocity on scapular kinematics. The effect of arm elevation velocity has been studied only in a two-dimensional setting. METHODS Thirty healthy subjects performed dominant (right) arm elevation in two planes, sagittal and frontal, and at slow and fast self-selected arm speed. Scapular orientation and humeral elevation were measured at 30 Hz recording frequency with use of a 6-degree-of-freedom electromagnetic system (Polhemus Fastraka). Motion was computed according to the International Society of Biomechanics standards. Scapular orientation was also determined with the arm held in different static positions. FINDINGS We obtained a full 3-D kinematic description of scapula achieving a reliable, complex 3-D motion during humeral elevation and lowering. The maximal sagittal arm elevation showed a characteristic "M"-shape pattern of protraction/retraction curve. Scapular rotations did not differ significantly between slow and fast movements. Moreover, protraction/retraction and tilt angular values did not differ significantly between static and dynamic tasks. However, scapular lateral rotation values differed between static and dynamic measurements during sagittal and frontal arm elevation. Lateral scapular rotation appears to be less in static than in dynamic measurement, particularly in the sagittal plane. INTERPRETATION Interpolation of statically recorded positions of the bones cannot reflect the kinematics of the scapula.

Abstract
This study summarizes the clinical and pathologic findings in 15 Labrador Retrievers with copper-associated chronic hepatitis (CACH). Our hypothesis was that this form of hepatitis is caused by a defect in hepatic copper metabolism, which most likely originates from a genetic defect. Affected Labradors consisted of 11 female and 4 male Labrador Retrievers. Eight family members of 2 of these patients were examined prospectively, as were 6 unrelated healthy Labrador Retrievers. All dogs were registered at the breed club. The average age at clinical presentation was 7 years (range, 2.5-10.5 years). All dogs were presented for anorexia, which was associated with vomiting in 8 patients. The diagnosis of CACH was based on histologic examination of liver biopsy specimens in all dogs, including semiquantitation of copper. A disproportionate increase in alanine aminotransferase (ALT) activity relative to alkaline phosphatase (ALP) activity, as well as the centrolobular localization of copper and the association of copper accumulation with hepatic lesions, suggested a primary copper storage disease rather than primary cholestatic liver disease causing copper accumulation. Mean hepatic copper concentration measured in related Labradors was 1,317 microg/g dry weight liver (range, 402-2,576 microg/g). Mean hepatic copper concentration of unrelated normal Labradors was 233 microg/g dry weight liver (range, 120-304 microg/g). Our findings support the hypothesis that a hereditary form of hepatitis occurs in Labrador retrievers and is caused by a defect in hepatic copper metabolism.

Abstract
Abstract
Background
Postoperative local water-filtered infrared A (wIRA) irradiation improves tissue oxygen partial pressure, tissue perfusion and tissue temperature, which are important in wound healing.
Methods
The effect of wIRA irradiation on abdominal wound healing following elective gastrointestinal surgery was evaluated. Some 111 patients undergoing moderate to major abdominal surgery were randomized into one of two groups: wIRA and visible light irradiation (wIRA group) or visible light irradiation alone (control group). Uncovered wounds were irradiated twice a day for 20 min from days 2–10 after operation.
Results
Irradiation with wIRA improved postoperative wound healing in comparison to visible light irradiation alone. Main variables of interest were: wound healing assessed on a visual analogue scale (VAS) by the surgeon (median 88·6 versus 78·5 respectively; P < 0·001) or patient (median 85·8 versus 81·0; P = 0·040), postoperative pain (median decrease in VAS score during irradiation 13·4 versus 0; P < 0·001), subcutaneous oxygen tension after irradiation (median 41·6 versus 30·2 mmHg; P < 0·001) and subcutaneous temperature after irradiation (median 38·9 versus 36·4 °C; P < 0·001). The overall result, in terms of wound healing, pain and cosmesis, measured on a VAS by the surgeon (median 79·0 versus 46·8; P < 0·001) or patient (79·0 versus 50·2; P < 0·001) was better after wIRA irradiation.
Conclusion
Postoperative irradiation with wIRA can improve normal postoperative wound healing and may reduce costs in gastrointestinal surgery.

Abstract
To study the influence of a 3-week hiking vacation at moderate (1700 m) and low altitude (LA) (200 m) on key-markers of the metabolic syndrome, 71 male volunteers (age 36-66 yr old) with the metabolic syndrome [according to the National Cholesterol Education Program's Adult Treatment Panel III (NCEP-ATP III) - or World Health Organization (WHO) - definition] participated in the study and were randomly assigned into a moderate altitude (MA) group (1700 m, no. 36) and a low altitude (LA) group (200 m, no. 35). The 3-week vacation program included 12 moderate- intensity guided hiking tours [4 times/week, 55-65% heart rate maximum (HRmax)] with a total exercise time of 29 h plus moderate recreational activities. Both study groups had a comparable and balanced nutrition with no specific dietary restrictions. Anthropometric, metabolic and cardiovascular parameters were measured 10-14 days before vacation, several times during the 3-week vacation, 7-10 days and 6-8 weeks after return. All participants tolerated the vacation without any adverse effects. Body weight, body fat, waist-circumference, fasting glucose, total cholesterol, LDL-cholesterol (LDL-C), plasma fibrinogen, resting systolic and diastolic blood pressure were significantly decreased over time in both study groups. In the LA group, fasting insulin and homeostasis model assessment (HOMA)-index were significantly decreased one week after return. Relative cycle ergometry performance was significantly increased after return compared to baseline. In both study groups, waist-to-hip ratio (WHR), 2-h oral glucose tolerance test (OGTT), HDL-cholesterol (HDL-C), and triglycerides remained unchanged. The 3-week vacation intervention at moderate and LA had a positive influence on all key-markers of the metabolic syndrome. No clinically relevant differences could be detected between the study groups. A hiking vacation at moderate and LA can be recommended for people with stable, controlled metabolic and cardiovascular risk factors.
