Abstract
Updated road databases are required for many purposes such as urban planning, disaster management, car navigation, route planning, traffic management and emergency handling. In the last decade, the improvement in spatial resolution of VHR civilian satellite sensors – as the main source of large scale mapping applications – was so considerable that GSD has become finer than size of common urban objects of interest such as building, trees and road parts. This technological advancement pushed the development of “Object-based Image Analysis (OBIA)” as an alternative to pixel-based image analysis methods. <br><br> Segmentation as one of the main stages of OBIA provides the image objects on which most of the following processes will be applied. Therefore, the success of an OBIA approach is strongly affected by the segmentation quality. In this paper, we propose a purpose-dependent refinement strategy in order to group road segments in urban areas using maximal similarity based region merging. For investigations with the proposed method, we use high resolution images of some urban sites. The promising results suggest that the proposed approach is applicable in grouping of road segments in urban areas.

Abstract
Mammographic breast density correlates with breast cancer risk and also with the number of false-negative calls. In the USA these facts lead to the "Breast Density and Mammography Reporting Act" of 2011. In the case of mammographically dense breasts, the Working Group on Breast Ultrasound in Germany recommends explaining the advantages of adjunct imaging to women, depending on the individual breast cancer risk. Due to the particular structure of German healthcare, quality-assured breast ultrasound would be the first choice. Possible overdiagnosis, costs, potentially increased emotional stress should be addressed. In high familial breast cancer risk, genetic counselling and an intensified early detection program should be performed.

Abstract
Cometary nuclei consist mostly of dust and water ice. Previous observations have found nuclei to be low-density and highly porous bodies, but have only moderately constrained the range of allowed densities because of the measurement uncertainties. Here we report the precise mass, bulk density, porosity and internal structure of the nucleus of comet 67P/Churyumov-Gerasimenko on the basis of its gravity field. The mass and gravity field are derived from measured spacecraft velocity perturbations at fly-by distances between 10 and 100 kilometres. The gravitational point mass is GM = 666.2 ± 0.2 cubic metres per second squared, giving a mass M = (9,982 ± 3) × 10(9) kilograms. Together with the current estimate of the volume of the nucleus, the average bulk density of the nucleus is 533 ± 6 kilograms per cubic metre. The nucleus appears to be a low-density, highly porous (72-74 per cent) dusty body, similar to that of comet 9P/Tempel 1. The most likely composition mix has approximately four times more dust than ice by mass and two times more dust than ice by volume. We conclude that the interior of the nucleus is homogeneous and constant in density on a global scale without large voids. The high porosity seems to be an inherent property of the nucleus material.

Abstract
Abstract
AIM
Evaluate within a pilot setup feasibility and safety of minimally invasive needle-biopsy of sentinel nodes guided by SPECT/US as compared to surgical removal while defining optimal needle for follow-up trial.
METHOD AND MATERIALS
As pretrial test phase of the MinimalSNB study, 38 breast cancer patients (6 centers) were taken a needle-biopsy of their sentinel lymph nodes (SLNs) under guidance of SPECT/US (SentiGuide by SurgicEye, Munich, DE). All patients were indicated for a surgical SLN biopsy which was performed immediately after the needle-biopsy. For the test phase, 4 different biopsy systems were tested: HistoCore 14G (BIP, Tuerkenfeld, DE), elite 10G and 13G (Mammotome, Cincinnati, OH, US) and CASSI II 10G (Scion Medical Technologies, Boston, MA, US). Histopathological examination (H&E, step-sectioning) of needle-biopsies and surgically removed SLNs were compared.
RESULTS
No single complication was reported. Occasionally, small hematomas could be found close to the SLN during surgery. Duration of complete procedure (imaging, needle placement, biopsy) took in average 17min. A learning curve was observed in duration (average after 5 biopsies 12min). 1-14 samples were taken of each SLN (average 5 samples). Final pathological examination of material harvested with both methods matched in 34 cases (33 negatives, 1 positive). The needle biopsy failed to detect metastases in 2 pN1 SLNs. In 1 case, the surgically resected tissue did not contain lymph nodes and the needle biopsy remained the only information on nodal status. In 1 case a metastasis found in needle-biopsy motivated a second reading of an originally negative SLN which resulted in the upstaging of the patient. In both cases a metastases was missed by needle-biopsy, the retrieved lymph tissue was minimal (1x 14G sample, 1x 10G sample tangential to node).
CONCLUSION
SPECT/US showed to be a valid method for percutaneous detection of SLNs and needle-guidance. Sampling SLNs with a needle seems safe and feasible. However it requires proper training and user experienced with axillary needle-biopsies. Retrieving more tissue (more cores and larger lumen needles) improves diagnostic power of needle-biopsy. These considerations will be taken within the upcoming MinimalSNB trial.
CLINICAL RELEVANCE
Sentinel lymph biopsy today is a surgical diagnostic procedure with an nonzero morbidity. Moving it out of the operating theatre to a needle-based intervention has a huge impact on the burden of this procedure for the patient as well as relevant improvements in logistics, workflow and radiation burden.

Abstract
Abstract
Background:
Completion of axillary lymph node dissection (ALND) was long lasting standard in patients with non-metastatic primary breast cancer (PBC) and axillary sentinel lymph node (SLN) involvement. However, this approach is currently questioned since recent prospective trials have found that some SLN-positive women with PBC might not benefit from subsequent ALND. Nomograms that estimate the probability of further non-sentinel lymph node (NSLN) metastases could guide clinical decisions.
Methods:
We compared the predictability of three different nomograms (MSKCC, Stanford University, Cambridge) on the NSLN status with an own logistic regression model in a training and validation set. SLN-positive women who underwent primary surgery including ALND at Tuebingen University, Germany, between 06/2005 - 12/2009 (training set) and 01/2010 - 02/2012 (validation set) were available for this analysis. The area under the receiver operating characteristics (ROC) curve was calculated for each nomogram.
Results:
295 and 175 patients were included into the training and validation set, respectively. Of these 118 (40%) and 57 (33%) patients were NSLN-positive. Variables within our model were tumor size, proportion of positive SLNs, size of SLN metastases, lymphangiosis carcinomatosa, multicentricity and extracapsular invasion. The respective area under the ROC curve values for the MSKCC / Stanford University / Cambridge / own regression model were 0.73 / 0.70 / 0.63 / 0.75 in the training set and 0.73 / 0.66 / 0.52 / 0.73 in the validation set.
Conclusion:
The predictability of our logistic regression model was comparable to the MSKCC nomogram and superior to the Stanford University and Cambridge nomogram. Although a training and a validation set was used, further testing on an independent patient population is warranted.

Abstract
The endoplasmic reticulum (ER) serves as the major intracellular Ca(2+) store and has a role in the synthesis and folding of proteins. BAX (BCL2-associated X protein) inhibitor-1 (BI-1) is a Ca(2+) leak channel also implicated in the response against protein misfolding, thereby connecting the Ca(2+) store and protein-folding functions of the ER. We found that BI-1-deficient mice suffer from leukopenia and erythrocytosis, have an increased number of splenic marginal zone B cells and higher abundance and nuclear translocation of NF-κB (nuclear factor-κ light-chain enhancer of activated B cells) proteins, correlating with increased cytosolic and ER Ca(2+) levels. When put into culture, purified knockout T cells and even more so B cells die spontaneously. This is preceded by increased activity of the mitochondrial initiator caspase-9 and correlated with a significant surge in mitochondrial Ca(2+) levels, suggesting an exhausted mitochondrial Ca(2+) buffer capacity as the underlying cause for cell death in vitro. In vivo, T-cell-dependent experimental autoimmune encephalomyelitis and B-cell-dependent antibody production are attenuated, corroborating the ex vivo results. These results suggest that BI-1 has a major role in the functioning of the adaptive immune system by regulating intracellular Ca(2+) homeostasis in lymphocytes.

Abstract
Introduction: Detection of sentinel lymph nodes (SLN) is the standard procedure to evaluate axillary lymph node status in breast cancer. In addition to known and established procedures such as the blue dye method and scintigraphy, this study investigated the efficacy of a method based on use of the fluorescent dye indocyanine green (ICG). Patients and Method: A total of 126 women with breast cancer histologically verified by punch biopsy were studied during surgical removal of SLN. In addition to SLN marking with technetium and scintigraphy, intra-individual comparison was done using indocyanine green (ICG) for marking instead of the standard blue dye. Results: Scintigraphy had a detection rate of 96 %; the detection rate with ICG was just under 89 %. A body mass index (BMI) > 40 was found to be a limiting factor for the fluorescent method. Investigation into potential toxicities associated with the use of the fluorescent dye ICG revealed no systemic or even local side effects. The fluorescent method was found to be significantly less expensive than the scintigraphy method. Conclusion: The ICG fluorescence technique for the detection of SLN was found to be a valid and feasible method in clinical practice when compared directly with the blue dye method and scintigraphy.

Radiofrequency Volumetric Thermal Ablation of Fibroids and Laparoscopic Myomectomy: Long-Term Follow-up From a Randomized Trial. Geburtshilfe Frauenheilkd 2015; 75:442-449.

Abstract
Aims: Laparoscopic myomectomy (LM) has been the gold standard treatment for uterine fibroids in women desiring uterine conservation. To evaluate a new fibroid treatment modality - radiofrequency volumetric thermal ablation (RFVTA) - we compare 12-month results in women who had symptomatic uterine fibroids and who were randomized to laparoscopic ultrasound-guided RFVTA or LM. Materials and Methods: Our study is a 1 : 1 parallel, randomized, prospective, single-center, longitudinal, comparative analysis of RFVTA to LM for fibroid treatment in women ≥ 18 years of age who desired uterine conservation. Fifty women were randomized intraoperatively to RFVTA (n = 25) or to LM (n = 25) after laparoscopic ultrasound mapping of the uterus. Results: Post surgery, ablation and myomectomy subjects took pain medications for 4 days (range: 1-46) and 7 days (range: 1-83 days) respectively (p = 0.60). Ablation and myomectomy subjects missed 10.0 workdays (range: 2-86 days) and 17.0 workdays (range: 7-30 days) (p = 0.28), resumed normal activities in 20.5 days (range: 5-103 days) versus 28.0 days (range: 10-42 days) (p = 0.86) respectively. Mean symptom severity scores decreased (improved) by - 7.8 for the ablation subjects and by - 17.9 for the myomectomy subjects (p = 0.16). Health-related quality of life improved (increased) by 7.5 and 13.1, respectively, for the two groups (p = 0.46). Two myomectomy subjects had pregnancies that ended in a Cesarean delivery and a vaginal delivery of healthy infants. Two pregnancies in the RFVTA group ended in full-term vaginal deliveries of healthy infants. Conclusions: Early postoperative recovery and twelve-month results attest to similar clinical benefits from RFVTA and LM.

Abstract
BACKGROUND Disseminated tumor cells (DTCs) are detectable in the bone marrow (BM) of patients with primary breast cancer (PBC) and predictive of an impaired prognosis. This large trial aimed to analyze the impact of DTC detection on locoregional relapse (LR). PATIENTS AND METHODS Patients with nonmetastatic PBC were eligible for this analysis. BM aspiration (BMA1) was carried out during primary surgery and DTCs were detected by using immunocytochemistry (A45-B/B3 antibody against pancytokeratin) and morphological criteria. At the time of LR, a subgroup of patients with nonmetastatic and operable LR received a secondary BM aspiration (BMA2). RESULTS A total of 3072 patients were included into the analysis. Of these, 732 (24%) presented with DTCs at BMA1. One hundred thirty-nine patients experienced LR and 48 of these (35%) were initially DTC positive. DTC detection was significantly associated with an increased risk of LR in univariate (P = 0.002) and multivariate analysis (P = 0.009) with a hazard ratio of 1.65 (95% confidence interval 1.13-2.40). Of the patients with LR, 55 patients were available for BMA2 and 17 of these (32%) were DTC positive. DTC detection at the time of LR was indicative of impaired overall survival (univariate analysis, P = 0.037). CONCLUSIONS DTC detection in patients with PBC is associated with an increased risk of LR, indicating that tumor cells may have the ability to recirculate from the BM to the site of the primary tumor. The impaired prognosis associated with DTC detection at the time of LR may help to identify patients that are in need for additional or more aggressive treatment.

Abstract
Antinuclear autoantibodies (ANA) are highly informative biomarkers in autoimmune diagnostics. The increasing demand for effective test systems, however, has led to the development of a confusingly large variety of different platforms. One of them, the indirect immunofluorescence (IIF), is regarded as the common gold standard for ANA screening, as described in a position statement by the American College of Rheumatology in 2009. Technological solutions have been developed aimed at standardization and automation of IIF to overcome methodological limitations and subjective bias in IIF interpretation. In this review, we present the EUROPattern Suite, a system for computer-aided immunofluorescence microscopy (CAIFM) including automated acquisition of digital images and evaluation of IIF results. The system was originally designed for ANA diagnostics on human epithelial cells, but its applications have been extended with the latest system update version 1.5 to the analysis of antineutrophil cytoplasmic antibodies (ANCA) and anti-dsDNA antibodies.

Abstract
OBJECTIVE This study's aim is the assessment of language development of children with Cochlea Implant (CI). It focusses on receptive and expressive language development as well as auditory memory skills. MATERIAL AND METHODS Grimm's language development test (SETK 3-5) evaluates receptive, expressive language development and auditory memory. Data of 49 children who received their implant within their first 3 years of life were compared to the norms of hearing children at the age of 3.0-3.5 years. According to the age at implantation the cohort was subdivided in 3 groups: cochlear implantation within the first 12 months of life (group 1), during the 13th and 24th months of life (group 2) and after 25 or more months of life (group 3). RESULTS It was possible to collect complete data of all SETK 3-5 subtests in 63% of the participants. A homogeneous profile of all subtests indicates a balanced receptive and expressive language development. Thus reduces the gap between hearing/language age and chronological age. Receptive and expressive language and auditory memory milestones in children implanted within their first year of life are achieved earlier in comparison to later implanted children. CONCLUSION The Language Test for Children (SETK 3-5) is an appropriate test procedure to be used for language assessment of children who received a CI. It can be used from age 3 on to administer data on receptive and expressive language development and auditory memory.

Abstract
Due to their well-established fracture risk reduction, bisphosphonates are the most frequently used therapeutic agent to treat osteoporosis. Bisphosphonates reduce fracture risk by suppressing bone resorption, but the lower bone turnover could have a negative impact on bone quality at the tissue level. Here, we directly assess the structural and mechanical characteristics of cancellous bone from the lumbar vertebrae (L5) in non-treated osteoporotic controls (n=21), mid-term alendronate-treated osteoporotic patients (n=6), and long-term alendronate-treated osteoporotic patients (n=7). The strength and toughness of single trabeculae were evaluated, while the structure was characterised through measurements of microdamage accumulation, mineralisation distribution, and histological indices. The alendronate-treated cases had a reduced eroded surface (ES/BS, p<0.001) and a higher bone mineralisation in comparison to non-treated controls (p=0.037), which is indicative of low turnover associated with treatment. However, the amount of microdamage and the mechanical properties were similar among the control and treatment groups. As the tissue mineral density (TMD) increased significantly with alendronate treatment compared to non-treated osteoporotic controls, the reduction in resorption cavities could counterbalance the higher TMD allowing the alendronate-treated bone to maintain its mechanical properties and resist microdamage accumulation. A multivariate analysis of the possible predictors supports the theory that multiple factors (e.g., body mass index, TMD, and ES/BS) can impact the mechanical properties. Our results suggest that long-term alendronate treatment shows no adverse impact on mechanical cancellous bone characteristics.

Abstract
PURPOSE The aim of this study was to evaluate the quality standard of the nationwide breast ultrasound training program of the German Society of Ultrasound in Medicine (DEGUM) through objective parameters. MATERIALS AND METHODS 10 quality criteria, based on the recommendations of The National Association of Statutory Health Insurance Physicians (KBV), were defined for this study. All training units of the DEGUM received a questionnaire. The questionnaires and training material were analyzed. RESULTS All units met the required criteria pertaining to the trainer's qualification, duration per training course and the maximum number of participants per ultrasound machine. Only 1 course did not fulfill the required 50 % practical training time. The requirements to participate in the graduate course (200 self-made and documented cases) were not clearly conceived and a defined training log could be improved. CONCLUSION DEGUM breast ultrasound training offers trainees a high level of education based on the requirements of the KBV. Despite the high quality of training, the content of course announcements could be improved and an official and structured educational index could be meaningful.

Abstract
The concentration of serum testosterone is mainly regulated by the testicular function, which is under control of the central hypothalamic-pituitary-gonadal axis. A certain amount of testosterone is converted into β-estradiol by adipose tissue. Obesity in men is often associated with decreased androgen levels. The aim of the present study was to examine the effect of caloric restriction on serum testosterone levels in obese men. Dietary intervention study was performed with a very low calorie diet (800 kcal/d) for 12 weeks. Thirteen obese human male subjects (median body mass index: 42.7 kg/m2) were included. Body composition was assessed by impedance analysis. Insulin sensitivity was estimated by leptin-to-adiponectin ratio (LAR). Testosterone (T), β-estradiol, albumin, sex hormone-binding globulin (SHBG), LH, and FSH serum concentrations were measured by enzyme immunoassays. Statistical analysis was performed on baseline and values after 3 months. Caloric restriction significantly increased total testosterone (6.97 nmol/l to 13.21 nmol/l; p=0.001) and SHBG (22.11 nmol/l to 42.12 nmol/l; p=0.001) concentrations in serum. This is caused by a significant improvement of the testicular function (LH/T: 0.36-0.20; p=0.005) and a significant reduction of the T/β-estradiol conversion rate (73.59-104.29; p=0.003). There was a significant negative correlation of improvement of testicular function and LAR (rs=-0.683 (p=0.042)). In obese men caloric restriction significantly increases the serum testosterone concentration. This is achieved by 2 distinct mechanisms, that is, improvement of testicular function and reduced conversion of testosterone to β-estradiol by aromatase activity of the adipose tissue.

Abstract
Purpose: Inflammatory myofibroblastic tumours (IMT) are a subcategory of inflammatory pseudotumours (IPT). They arise most commonly in the abdominopelvic region, lung and retroperitoneum, but virtually any anatomical site may be involved. Predominantly children and adolescents are affected and there is a tendency for local recurrence. In the literature up to the present, 20 patients have been reported with an IPT/IMT of the breast. We would like to present another patient with this unusual tumour entity of the breast and discuss the literature. Patient and Examinations: A 23-year-old woman presented with a painless lump in her left breast. There was no history of breast cancer in her family. Sonography showed a hypoechoic heterogeneous solid mass with irregular margins. A core needle biopsy revealed a tumour of high cellularity and a densely collagenous background. Immunohistochemically, the spindle-shaped cells were immunoreactive to smooth muscle actin and ALK-1 protein. Additional FISH analysis proved ALK rearrangements on chromosome 2p23 leading to the diagnosis of an IMT. Wide surgical excision was performed with no evidence of local recurrence after 12 months. Conclusion: Three of the above mentioned 20 patients with IMT/IPT of the breast developed a recurrent tumour, none presented with distant metastasis. A significant recurrence rate of 15 % leads to a clinically and sonographically close follow-up in these patients.

Abstract
PURPOSE Sonoelastography of the breast is an emerging technology with evident data in the literature suggesting diagnostic advantages. Our study investigates the current usage of sonoelastography among German DEGUM-certified breast ultrasound specialists. MATERIALS AND METHODS We used a standardized questionnaire with 18 items. In 2012, the survey was sent to all members of the breast ultrasound section of the DEGUM (n = 654). RESULTS The group of survey participants (n = 208) performs 193 025 breast ultrasound examinations and examines 20 110 breast cancers per year. 21.2 % of the participants in the survey use sonoelastography, mainly for diagnostic purposes in BI-RADS®-US 3 and 4 lesions, less often for other categories or under study conditions. The most commonly applied criteria for the evaluation of the elastogram are the Tsukuba Elasticity Score (43.2 %), the fat-lesion ratio (29.5 %) and the determination of tissue stiffness with shear wave elastography expressed in kilopascal (25.0 %). The majority of non-users of elastography (58.6 %) would like to have the option of using sonoelastography in the future. CONCLUSION Sonoelastography is a feasible and helpful method in the evaluation of breast lesions. A significant number of German ultrasound specialists already apply this technology today. We expect a growing number of sonographers to perform sonoelastography in the near future, provided that they have the necessary ultrasound system and that they are trained in the method. Evidence from the literature and the recommendations of the medical societies support this development.

Abstract
SUMMARY We analyzed morphological characteristics of osteons along with the geometrical indices of individual osteonal mechanical stability in young, healthy aged, untreated osteoporotic, and bisphosphonate-treated osteoporotic women. Our study revealed significant intergroup differences in osteonal morphology and osteocyte lacunae indicating different remodeling patterns with implications for fracture susceptibility. INTRODUCTION Bone remodeling is the key process in bone structural reorganization, and its alterations lead to changes in bone mechanical strength. Since osteons reflect different bone remodeling patterns, we hypothesize that the femoral cortices of females under miscellaneous age, disease and treatment conditions will display distinct osteonal morphology and osteocyte lacunar numbers along with different mechanical properties. METHODS The specimens used in this study were collected at autopsy from 35 female donors (young group, n = 6, age 32 ± 8 years; aged group, n = 10, age 79 ± 9 years; osteoporosis group, n = 10, age 81 ± 9 years; and bisphosphonate group, n = 9, age 81 ± 7 years). Von Kossa-modified stained femoral proximal diaphyseal sections were evaluated for osteonal morphometric parameters and osteocyte lacunar data. Geometrical indices of osteonal cross-sections were calculated to assess the mechanical stability of individual osteons, in terms of their resistance to compression, bending, and buckling. RESULTS The morphological assessment of osteons and quantification of their osteocyte lacunae revealed significant differences between the young, aged, osteoporosis and bisphosphonate-treated groups. Calculated osteonal geometric indices provided estimates of the individual osteons' resistance to compression, bending and buckling based on their size. In particular, the osteons in the bisphosphonate-treated group presented improved osteonal geometry along with increased numbers of osteocyte lacunae that had been formerly impaired due to aging and osteoporosis. CONCLUSIONS The data derived from osteons (as the basic structural units of the cortical bone) in different skeletal conditions can be employed to highlight structural factors contributing to the fracture susceptibility of various groups of individuals.

Abstract
PURPOSE Fibroadenoma (FA) of the breast is the most common disorders in young women. The aim of the study was to evaluate cryoablation (CA) under ultrasound guidance in the office setting for patients with FA. MATERIALS AND METHODS For this prospective multicenter trial an office-based cryosurgical system was used to treat histological confirmed benign FA with a maximum dimension of 3 cm. 23 CA procedures were performed under ultrasound guidance. The cryoprobe was inserted into the center of the FA guided by real-time ultrasound. A freeze-thaw-freeze treatment cycle was performed according to the size of the FA. During the CA procedure continuous ultrasound monitoring of the ice ball was performed, verifying engulfment of the FA. Patients attended 4 follow-up visits at 1 week, 3 months, 6 months and 1 year and underwent ultrasound and physical examinations. RESULTS Data was collected from 23 procedures. The ice ball engulfed the treated FA in 91.3 %. A sharp reduction in volume was observed at 6-month follow-up and continued more moderately up to 1 year. No serious but four minor adverse events occurred. At 1 year follow-up, lumps that were assessed pre-treatment as hard were assessed as soft or not palpable. 7 patients complained of pain caused by the lump prior to cryotherapy, while 5 of these patients felt transient pain during the follow up period. It is reasonable to assume that the pain was not related to the CA procedure as it was not consistent. In 96 % of the cases patients and physicians rated the cosmetic results of the procedure as excellent or good. CONCLUSION The cryodestruction proved functional and safe, while showing reduction in palpability and pain caused by the FA in the treated patients.
