A study on mastectomy samples to evaluate breast imaging quality and potential clinical relevance of differential phase contrast mammography.

Objectives: Differential phase contrast and scattering-based x-ray mammography has the potential to provide additional and complementary clinically relevant information compared with absorption-based mammography. The purpose of our study was to provide a first statistical evaluation of the imaging capabilities of the new technique compared with digital absorption mammography.

Materials And Methods: We investigated non-fixed mastectomy samples of 33 patients with invasive breast cancer, using grating-based differential phase contrast mammography (mammoDPC) with a conventional, low-brilliance x-ray tube.

Hysterosalpingography in the workup of female infertility: indications, technique and diagnostic findings.

Objectives: To evaluate the spectrum of diagnostic findings in hysterosalpingography (HSG) examinations performed at our institution between 2006-2010 and their prognostic significance for treatment decisions and fertility outcomes.

Methods: Patients were filtered from our PACS. Pathological HSG studies were re-evaluated.

The first analysis and clinical evaluation of native breast tissue using differential phase-contrast mammography.

Objectives: Phase-contrast and scattering-based x-ray imaging are known to provide additional and complementary information to conventional, absorption-based methods, and therefore have the potential to play a crucial role in medical diagnostics. We report on the first mammographic investigation of 5 native, that is, freshly dissected, breasts carried out with a grating interferometer and a conventional x-ray tube source. Four patients in this study had histopathologically proven invasive breast cancer.

MRI of the female pelvis: a possible pitfall in the differentiation of haemorrhagic vs. fatty lesions using fat saturated sequences with inversion recovery.

The use of fat-saturated techniques should be an integral part of the work-up of any T1-hyperintense structure in the female pelvis for tissue characterization and for differentiation of a fat-containing ovarian mature teratoma from a haemorrhagic lesion. Two cases with haematocolpos and haematometra are presented, respectively. The haemorrhagic content showed high signal both on T1- and T2-weighted images, whereas an unexpected signal decrease in the fat-saturated T2-weighted inversion-recovery sequence was encountered.

Successful remission of extensive liver metastases in a breast cancer patient with acute liver failure using a combined chemotherapy regimen with mitomycin, folinate, and 5-fluorouracil (Mi/Fo/FU).

Background: Liver failure due to disseminated hepatic secondaries represents a therapeutic dilemma in patients with metastatic breast cancer (MBC). Reduced liver function and non-assessable toxicity are limiting factors in the selection of chemotherapeutic agents. Currently, there is no standard treatment after failure of anthracycline-and taxane-based first-line therapies, although there is a variety of well evaluated drugs such as capecitabine.

Safe total intrafascial laparoscopic (TAIL) hysterectomy: a prospective cohort study.

This study directly compares total intrafascial laparoscopic (TAIL) hysterectomy with vaginal (VH) and abdominal (AH) hysterectomy with regard to safety, operating time and time of convalescence. The study is a prospective cohort study (Canadian Task Force classification II-2), including data from patients of a single university-affiliated teaching institution, admitted between 1997 and 2008 for hysterectomy due to benign uterus pathology. Patient data were collected pre-, intra- and postoperatively and complications documented using a standardised data sheet of a Swiss obstetric and gynaecological study group (Arbeitsgemeinschaft Schweizerische Frauenkliniken, Amlikon/Switzerland).

Pronuclear zygote score following intracytoplasmic injection of hyaluronan-bound spermatozoa: a prospective randomized study.

The aim of this study was to determine whether the early stages of embryo development, as assessed by the zygote score (Z-score), could be influenced by the injection of spermatozoa that had been preselected on the basis of their binding to hyaluronic acid (HA). A total of 407 sibling metaphase II oocytes, belonging to 44 different patients, were injected in a prospective randomized way, with either hyaluronic acid bound (HA(+) ) or non-bound (HA(-)) spermatozoa. The fertilization rate (75-70%), the percentage of the different Z-scores (Z 1: 22-24%, Z 2: 22-22.

Attitudes of couples towards the destination of surplus embryos: results among couples with cryopreserved embryos in Switzerland.

Background: The purpose of this study was to investigate attitudes towards the donation of surplus embryos among couples with cryopreserved embryos/zygotes, and to identify correlates associated with attitudes toward the destinations of surplus embryos/zygotes.

Methods: Eleven of 19 Swiss in vitro fertilization (IVF) centers in existence in 2004 participated in the survey. Questionnaires were sent to 888 eligible couples; 458 men (52%) and 468 women (53%) returned them.

Ten years of Swiss National IVF Register FIVNAT-CH. Are we making progress?

In 2001, analysis of Swiss data collected since 1993 included 1001 treatment cycles with IVF, 2217 treatment cycles with intracytoplasmic sperm injection and 2160 treatment cycles with frozen-thawed embryos or zygotes. IVF cycle number has remained constant over the past 10 years, now representing only 18% of the total. ICSI treatment cycles have plateaued since 2001.
