Abstract
BACKGROUND Magnetic resonance imaging (MRI)/ultrasound (US) fusion-guided biopsy detects more prostate cancer (PCa) than transrectal US (TRUS)-guided biopsy in patients with an indication for prostate re-biopsy. The aim of this study was a) to compare the detection rates of MRI/US fusion-guided biopsy with conventional TRUS in a double centre cohort and b) to investigate the influence of the number of pre-biopsies on the PCa detection rate. MATERIAL AND METHODS In the period from January 2012 to July 2014, 310 consecutive patients gave written informed consent and underwent 3 Tesla MRI scans of the prostate. All patients had at least one PCa suspicious lesion in the MRI and were biopsied by MRI/US fusion followed by a conventional 10-core biopsy of the prostate. Detection rates based on technique, Gleason score and number of pre-biopsies were calculated. RESULTS The overall detection rate of the study was 51% (158 patients). Among these 158 patients a histopathological Gleason score of 6 was detected in 60 patients (38%), a Gleason score of 7 in 54 patients (34%) and a Gleason score≥8 in 44 patients (28%). MRI/US fusion-guided biopsy detected 110 (69.7%) of the overall detected 158 PCa. TRUS-guided biopsy detected a higher rate of Gleason score 6 (54%) and a lower rate of Gleason score≥8 (15%) lesions in comparison to 38% Gleason 6 and 28% Gleason≥8 in the MRI/US fusion-guided biopsy, respectively. Furthermore, a lower Gleason score was observed in patients with more than one pre-biopsy. The detection rate in biopsy-naïve patients undergoing MRI/US fusion was 75% (40 patients) among 75% detected Gleason score≥7. CONCLUSION MRI/US fusion-guided biopsy detected more PCa and also more clinically significant cancer than conventional TRUS. In our cohort patients with more than one pre-biopsy showed lower Gleason scores. The included patients with an initial MRI/US fusion-guided biopsy should be further investigated.

Abstract
PURPOSE Microcalcifications in the breasts can point to breast cancer. However, there is great morphologic variety, and microcalcifications do not always correlate with malignancy. We conducted a prospective study to compare ultrasound and mammography in the detection of microcalcifications following sonographic diagnosis of a hypoechoic focal lesion in women with dense breast composition. MATERIALS AND METHODS A total of 104 lesions potentially associated with microcalcifications (82 malignant and 23 benign lesions) were included in the study. The breast was examined by ultrasound (9 MHz, Aplio XG/500) with additional use of MicroPure imaging for the demonstration and evaluation of microcalcifications. The presence of a focal lesion was verified and microcalcifications were counted at ultrasound and mammography by blinded readers. The sensitivity and specificity were determined, and ROC analysis and AUC analysis were performed. RESULTS The women had a median age of 51 years. The average number of microcalcifications detected by sonography (2.12 ± 2.77) and mammography (3.59 ± 6.35) was not significantly different (p > 0.05). Correlation of the techniques was adequate (Pearson's r = 0.616, p < 0.0001; Spearman's rho = 0.654, p < 0.0001). The intraclass correlation coefficient was K = 0.382 ± 0.072 (p < 0.0001), also indicating adequate agreement of both techniques. The sensitivity and specificity were 70%/30% for MicroPure and 45%/55% for mammography. The positive predictive value of mammography was superior to that of MicroPure (88% vs. 78%). CONCLUSION The sonographic detection of microcalcifications with MicroPure imaging in breasts with a hypoechoic focal lesion correlates well with digital mammography.

Abstract
PURPOSE To evaluate an irregular perilesional hyperechoic zone as a potential criterion of malignancy on breast ultrasound and to test whether this zone correlates with perilesional T2 hyperintensity on magnetic resonance imaging (MRI). MATERIALS AND METHODS A total of 137 patients (85 malignant lesions, 52 benign lesions) who underwent breast ultrasound with a 9 - 14 MHz linear broad-spectrum transducer and consecutive ultrasound-guided biopsy were included. All patients additionally underwent breast MR imaging with dedicated breast coils at 1.5 T. The protocol included a T2-weighted sequence. Perilesional hyperechoic and T2 hyperintense areas were measured by planimetry using the slice showing maximum extension of this area. The sensitivity and specificity of the perifocal area for identifying breast malignancy were determined using ROC analysis. Correlation was assessed using Pearson analysis. RESULTS The presence of a hyperechoic zone identified malignancy with a sensitivity of 87% and a specificity of 81%. Additionally, there was a highly significant correlation of the size of the hyperechoic zone with the degree of tumor differentiation (p = 0.002) as well as with the mib-1 proliferation index (p = 0.006) and lymphangio-invasion (p = 0.02). No significant correlation was found between the hyperchoic zone and the T2 hyperintense zone on MRI (R2 = 0.16). CONCLUSION A hyperechoic zone surrounding breast lesions may serve as an additional sonomorphologic criterion of malignancy. Yet, it does not seem to correlate with edema on MRI.

Abstract
Erythropoiesis is a tightly regulated process. Development of red blood cells occurs through differentiation of hematopoietic stem cells (HSCs) into more committed progenitors and finally into erythrocytes. Binding of erythropoietin (Epo) to its receptor (EpoR) is required for erythropoiesis as it promotes survival and late maturation of erythroid progenitors. In vivo and in vitro studies have highlighted the requirement of EpoR signaling through Janus kinase 2 (Jak2) tyrosine kinase and Stat5a/b as a central pathway. Here, we demonstrate that phospholipase C gamma 1 (Plcγ1) is activated downstream of EpoR-Jak2 independently of Stat5. Plcγ1-deficient pro-erythroblasts and erythroid progenitors exhibited strong impairment in differentiation and colony-forming potential. In vivo, suppression of Plcγ1 in immunophenotypically defined HSCs (Lin(-)Sca1(+)KIT(+)CD48(-)CD150(+)) severely reduced erythroid development. To identify Plcγ1 effector molecules involved in regulation of erythroid differentiation, we assessed changes occurring at the global transcriptional and DNA methylation level after inactivation of Plcγ1. The top common downstream effector was H2afy2, which encodes for the histone variant macroH2A2 (mH2A2). Inactivation of mH2A2 expression recapitulated the effects of Plcγ1 depletion on erythroid maturation. Taken together, our findings identify Plcγ1 and its downstream target mH2A2, as a 'non-canonical' Epo signaling pathway essential for erythroid differentiation.

Abstract
BACKGROUND Latin American formation dancing ranks among the technical-compositional types of sport and represents a discipline of dance sport due to its performance- and competition-orientated mode. Despite its high degree of popularity and a movement profile favouring injuries, there has been a lack of studies as to health hazards and damage in Latin American formation dancing. The aim of this study is to analyse formation dance-related health hazards and their causes. METHODS A total of n = 100 (m: n = 52, f: n = 48) Latin American dancers of the German top-level league participated in this anonymised retrospective cross-sectional investigation. RESULTS Mean weights of the male dancers were 75.2 kg and respectively 58.2 kg for the females, mean body height/size were 1.82 m (m) and 1.67 m (f) and mean BMI 22.2 (m) and 20.0 (f), respectively. At least one each traumatic injury/chronic damage was sustained by 69.3 % (m) and 77.6 % (f) of the dancers in the course of their dance sport activities. Almost all (97.9 %) injuries occurred during the training. A total of 409 injuries/overuse damages (= 4.1 injuries/athlete) was reported with 80.4 % traumatic injuries and 19.5 % chronic damages. Female dancers were more often injured than their male counterparts. The lower extremity was the most commonly affected body region [64.5 % (m) and, respectively, 71.2 % (f)], followed by upper extremity (m: 21.2 %, f: 17.6 %) and spinal column/trunk region (m: 12.0 %, f: 8.5 %). Blockages and pulled muscles were the most common complaints reported by males with contusions and pulled muscles being reported by females. Chondropathy/osteoarthrosis were the most frequent chronic diseases. Of all injuries sustained, circa two thirds were caused by extrinsic and circa one third by intrinsic factors. CONCLUSION The injury profiles/patterns in Latin American formation dancing show on the one hand parallels to the individual partner dances. On the other hand, typical and gender-specific movement elements seem to reflect in the injuries and chronic damages/diseases of formation dancers. This is to be taken into account when injury prevention measures are considered. There is also a need for further studies to allow a more differentiated analysis.

Abstract
BACKGROUND According to the guidelines of the European Association of Urology (EAU) on prostate cancer (PCa) in 2013, patients with increasing prostate-specific antigen (PSA) levels, suspicious digital rectal examination (DRE) or high-grade prostatic intraepithelial neoplasia after negative prostate biopsy (PB) should undergo a repeat biopsy. Low cancer detection rates in the repeat biopsy illuminate the dilemma of the international gold standard of transrectal ultrasound (TRUS) guided PB in the detection of PCa. Our study evaluated the combination of TRUS and prostate magnetic resonance imaging (MRI) and its reported high sensitivities and high specificities by using real-time MRI/US fusion-guided biopsy. The detection of clinically significant PCa was investigated. MATERIAL AND METHODS 128 consecutive patients in the period of January 2012 to August 2013 were included. All patients had at least one TRUS-guided biopsy with negative findings and the clinical indication for a systematic re-biopsy. Prior to the MRI/US fusion all patients underwent a 3 Tesla prostate MRI without endorectal coil. The MRI data were uploaded to a modern US system. The B-mode, power-mode, elastography and CEUS imaging were used to classify the suspicious lesions from the MRI on a scale of 0-3 and a US sum score was calculated. The lesion was consecutively biopsied by real-time MRI/US fusion followed by a systematic 10 core biopsy. RESULTS Among 128 patients 51 PCa could be detected (39.8%). From these 51 PCa cases, clinically significant PCa was detected by MRI/US fusion-guided biopsy as follows: Gleason score >7 in 9 of 10 patients; Gleason score=7 in 14 of 20 patients and Gleason score <7 in 13 of 21 patients. A positive correlation was shown between the US sum score and the associated PI-RADS score in 65 patients in whom lesions were classified by PI-RADS. A positive correlation was further shown between the US sum score and the Gleason score of all suspicious and biopsied lesions. MRI/US fusion and TRUS-guided biopsy combined, detected 30 of 51 PCa; 6 of 51 PCa were detected by MRI/US fusion alone and 15 of 51 PCa by conventional TRUS-guided biopsy alone. CONCLUSION Real-time MR/US fusion increases detection rates of PCa in patients undergoing repeat biopsy. Especially, clinically significant PCa with a Gleason score ≥ 7 were almost exclusively detected by MR/US fusion-guided biopsy.
