Methods: This is a multicentre, controlled study of obstetric patients who gave birth during an inpatient stay.

Best Practice Guideline - DEGUM Recommendations on Breast Ultrasound.

Alongside mammography, breast ultrasound is an important and well-established method in assessment of breast lesions. With the "Best Practice Guideline", the DEGUM Breast Ultrasound (in German, "Mammasonografie") working group, intends to describe the additional and optional application modalities for the diagnostic confirmation of breast findings and to express DEGUM recommendations in this Part II, in addition to the current dignity criteria and assessment categories published in Part I, in order to facilitate the differential diagnosis of ambiguous lesions.The present "Best Practice Guideline" has set itself the goal of meeting the requirements for quality assurance and ensuring quality-controlled performance of breast ultrasound.

Axillary Staging after Neoadjuvant Chemotherapy for Initially Node-Positive Breast Carcinoma in Germany: Initial Data from the AXSANA study.

To date, the optimal axillary staging procedure for initially node-positive breast carcinoma patients after neoadjuvant chemotherapy (NACT) has been unclear. The aim of the AXSANA study is to prospectively compare different surgical staging techniques with respect to the oncological outcome and quality of life for the patients. Little is known about current clinical practice in Germany.

Best Practice Guideline - DEGUM Recommendations on Breast Ultrasound.

For many years, breast ultrasound has been used in addition to mammography as an important method for clarifying breast findings. However, differences in the interpretation of findings continue to be problematic 1 2. These differences decrease the diagnostic accuracy of ultrasound after detection of a finding and complicate interdisciplinary communication and the comparison of scientific studies 3.

Quality of Life, Sexuality, Anatomical Results and Side-effects of Implantation of an Alloplastic Mesh for Cystocele Correction at Follow-up after 36 Months.

Introduction: Pelvic organ prolapse can significantly reduce quality of life of affected women, with many cases requiring corrective surgery. The rate of recurrence is relatively high after conventional prolapse surgery. In recent years, alloplastic meshes have increasingly been implanted to stabilize the pelvic floor, which has led to considerable improvement of anatomical results.

Pelvic organ prolapse surgery in elderly patients.

Purpose: Pelvic organ prolapse (POP) can cause incomplete bladder emptying or hydronephrosis and renal failure. These are serious conditions, especially in elderly women, requiring resolution of POP. Pessary use is an alternative, but there are specific problems or patients may not want it.

Improvement of pelvic floor-related quality of life and sexual function after vaginal mesh implantation for cystocele: primary endpoint of a prospective multicentre trial.

Purpose: Pelvic organ prolapse (POP) impairs quality of life (QoL) due to vaginal bulge symptoms and changes in bladder/bowel and sexual function. The effect of alloplastic meshes on QoL is still being discussed. The purpose of this study was to prospectively evaluate the effect of mesh implantation on QoL and sexual function over 1 year.

Functional outcome after pelvic floor reconstructive surgery with or without concomitant hysterectomy.

Purpose: When counseling patients about surgical alternatives for pelvic organ prolapse (POP) repair, numerous things have to be considered. Uterine preservation vs. hysterectomy is one relevant issue.

Mesh implantation for pelvic organ prolapse improves quality of life.

Purpose: The use of alloplastic meshes for repair of female pelvic organ prolapse (POP) has recently been discussed for its indications and safety. Mesh exposure and chronic pelvic pain are among the risks that need to be addressed to the patients. The purpose of this prospective observational study is to investigate the effect of vaginal mesh implantation on pelvic floor-related quality of life (QoL).

Basal-like molecular subtype and HER4 up-regulation and response to neoadjuvant chemotherapy in breast cancer.

Alteration of gene expression profiles during chemotherapy may predict response to neoadjuvant chemotherapy (NAC) in breast cancer patients. In a prospective cohort study of 32 women with primary invasive breast cancer, we obtained tumor specimens before and after 4 cycles of NAC with epirubicine 90 mg/m2 and cyclophosphamide 600 mg/m2, followed by 4 cycles of docetaxel 100 mg/m2. Total-RNA was extracted from tumor specimens and the whole transcriptome was analyzed with Agilent's 44K single color microarray.

Pegylated liposomal doxorubicin and trastuzumab as 1st and 2nd line therapy in her2/neu positive metastatic breast cancer: a multicenter phase II trial.

The combination therapy of doxorubicin and trastuzumab has been proven to be highly effective for metastatic breast cancer (MBC) patients with Her2/neu over-expressing tumors. However, this regimen is characterized by frequent cardiac toxicity, occurring in 27% of all treated patients and aggravating when the two substances are given concurrently. Pegylated liposomal doxorubicin (PLD) as a single agent reduces significantly cardiac toxicity and maintains efficacy compared to conventional doxorubicin.

Increased soluble CD44 concentrations are associated with larger tumor size and lymph node metastasis in breast cancer patients.

Purpose: CD44 is a cell surface glycoprotein involved in cell-cell and cell-substrate interactions, which may be shed or released into circulation by proteolytic enzymatic mechanisms. Alternative splicing of CD44 and aberrant levels of soluble CD44 variants in the serum of cancer patients have been correlated to tumor progression and metastasis in different tumors including breast cancer. In this study we evaluated the clinical value of CD44 serum levels (sCD44) in patients with primary breast cancer.

Salicylate alters the expression of calcium response transcription factor 1 in the cochlea: implications for brain-derived neurotrophic factor transcriptional regulation.

Brain-derived neurotrophic factor (BDNF) is a key neurotrophin whose expression is altered in response to neurological activity, influencing both short- and long-term synaptic changes. The BDNF gene consists of eight upstream exons (I-VII), each of which has a distinct promoter and can be independently spliced to the ninth coding exon (IX). We showed recently that the expression of BDNF exon IV in the cochlea is altered after exposure to salicylate, an ototoxic drug that in high doses is able to induce hearing loss and tinnitus.

Surgical repair of posterior compartment prolapse: preliminary results of a novel transvaginal procedure using a four-armed polypropylene mesh with infracoccygeal and pararectal suspension.

Background: Anatomical defects of the posterior vaginal compartment are a common reason for pelvic floor reconstructive surgery. The implantation of a four-armed monofilamentous polypropylene mesh with infracoccygeal and pararectal suspension is a recently introduced innovative technique, which is believed to reduce the risk of mesh retraction and prolapse recurrences, and additionally, allows a tension-free adjustment of the mesh.

Methods: In this preliminary case series, we aimed to evaluate feasibility, intraoperative complications and short-term follow-up results of this novel surgical procedure in a multicentre approach.

Transketolase protein TKTL1 overexpression: A potential biomarker and therapeutic target in breast cancer.

Malignant tumors degrade glucose to lactate even in the presence of oxygen via the pentose phosphate pathway (ppp). The non-oxidative part of the ppp is controlled by thiamine-dependant transketolase enzyme reactions. Overexpression of the transketolase-like-1-gene (TKTL1) in urothelial and colorectal cancer is associated with poor patient outcome.

Splicing factor Tra2-beta1 is specifically induced in breast cancer and regulates alternative splicing of the CD44 gene.

The human CD44 gene undergoes extensive alternative splicing of multiple variable exons positioned in a cassette in the middle of the gene. Expression of alternative exons is often restricted to certain tissues and could be associated with tumor progression and metastasis of several human malignancies, including breast cancer. Exon v4 contains multiple copies of a C/A-rich exon enhancer sequence required for optimal inclusion of the exon and binding to the nucleic acid-binding proteins YB-1 and human Tra2-beta1.

Increased expression of matrix metalloproteinase 2 in uterosacral ligaments is associated with pelvic organ prolapse.

The uterosacral ligaments are an important part of the pelvic support system and connective tissue alterations are thought to contribute to the development of pelvic organ prolapse (POP). The objective of this study was to compare the expression of matrix metalloproteinases (MMPs) 1 and 2 in these ligaments in women with and without POP. We analyzed the tissue samples obtained from left and/or right uterosacral ligaments of 17 women with POP and 18 controls by immunohistochemistry.

Polymorphism of the p53 tumor suppressor gene is associated with susceptibility to uterine leiomyoma.

Objective: To evaluate the association between the presence of uterine leiomyoma and two single nuclear polymorphisms of the p53 tumor suppressor and the angiopoietin-2 (ANGPT2) genes.

Design: Prospective case control study.

Setting: Academic research institution.

Uterosacral ligament in postmenopausal women with or without pelvic organ prolapse.

The uterosacral ligaments are thought to contribute to pelvic support. The objective of this study was to compare the structural components of these ligaments in women with and without pelvic organ prolapse (POP). We characterized uterosacral ligaments of 25 postmenopausal women with POP and 16 controls histomorphologically and immunohistochemically by quantifying their content of collagen I, III, and smooth muscle using a computerized image analysis.

Ultrasound morphology of invasive lobular breast cancer is different compared with other types of breast cancer.

The aim of this study was to evaluate the ultrasound (US) morphology of invasive lobular breast carcinomas (ILC) in comparison to that of invasive tumors of other histologic differentiation (TOD). Images of 406 breast lesions were included in this retrospective study. A total of 10 US criteria (shape, orientation, echogenicity, echo pattern, calcifications, margin, margin contour, lesion boundary, surrounding tissue and posterior acoustic features) were defined and determined.

Ultrasound criteria for ductal invasive breast cancer are modified by age, tumor size, and axillary lymph node status.

Purpose: To evaluate the influence of distinct clinicopathological parameters on ultrasound criteria for ductal invasive breast cancer.

Patients And Methods: The hardcopy prints of 337 ductal invasive breast cancers were analyzed. Ten ultrasound criteria (shape, orientation, echogenicity, echo pattern, calcifications, margin, margin contour, lesion boundary, surrounding tissue, and posterior acoustic features) were defined and correlated to age, tumor size, axillary lymph node status, and histological grading in a multivariate analysis.
