OBJECTIVES: This study aimed to investigate the effects of adding adjunct mechanical imaging to mammography breast screening. We hypothesized that mechanical imaging could detect increased local pressure caused by both malignant and benign breast lesions and that a pressure threshold for malignancy could be established. The impact of this on breast screening was investigated with regard to reductions in recall and biopsy rates. METHODS: 155 women recalled from breast screening were included in the study, which was approved by the regional ethical review board (dnr 2013/620)...

The present study investigates the cerebral effects of chronic occupational stress and its possible reversibility. Forty-eight patients with occupational exhaustion syndrome (29 women) and 80 controls (47 women) underwent structural magnetic resonance imaging (MRI) and neuropsychological testing. Forty-four participants (25 patients, 19 controls) also completed a second MRI scan after 1-2 years. Only patients received cognitive therapy. The stressed group at intake had reduced thickness in the right prefrontal cortex (PFC) and left superior temporal gyrus (STG), enlarged amygdala volumes, and reduced caudate volumes...

Strain elastography (SE) is a new technique of parametric imaging that allows quantification of the elasticity of tissue. The aim of our study was to determine if the elasticity of para-urethral tissue correlates with urethral mobility and urinary incontinence (UI). Ninety-nine unselected women were investigated with SE. They were given a standardized interview about UI, and SE raw data for the para-urethral tissue were acquired in a sagittal standard urethra-symphysis view while being stimulated by a coughing fit...

OBJECTIVES: Urinary incontinence (UI) is a common condition, but despite the availability of guidelines, variations exist in the care of patients. We sought to assess the changes in assessment and management of women with UI over time in the United States. METHODS: The National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey are annual surveys from a nationally representative sample of visits to physicians. From 1999 through 2010, we identified visits by women to physicians where the chief complaint was UI using reason-for-visit and International Classification of Diseases, Ninth Revision codes...

BACKGROUND: Breast cancer is one of the most common type of female cancer worldwide and represents 14% of cancer-related deaths in women. Early detection is the most important factor for treatment and prognosis of breast cancer. In most countries, the women are currently screened with mammography only. Even though there has been considerable progress in the detection, surgical therapy, hormonal and target therapy of breast cancer, there are about ∼ 3500 000 women who die from breast cancer each year...

As breast cancer tissues are stiffer than normal tissues, shear wave elastography (SWE) can locally quantify tissue stiffness and provide histological information. Moreover, tissue stiffness can be observed on three-dimensional (3D) colour-coded elasticity maps. Our objective was to evaluate the diagnostic performances of quantitative features in differentiating breast masses by two-dimensional (2D) and 3D SWE. Two hundred ten consecutive women with 210 breast masses were examined with B-mode ultrasound (US) and SWE...

BACKGROUND: Patients with end-stage renal disease have the highest 30-day hospital readmission rates of any medical condition. Previous research suggests that cognitive impairment contributes to readmission. It is important to identify patients at risk for early readmission, and this might be accomplished efficiently using medical record data. METHOD: We reviewed the medical records of 100 patients with kidney disease (57 women, mean age = 61.2) who were hospitalized in the nephrology unit at an urban U...

OBJECTIVES: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the XXX Breast Cancer Screening Program (XBCSP), the recommended range of compression force for full field digital mammography is 11-18 kg (108-177 Newton [N]). This is the first study to investigate the compression force used in the program. METHODS: The study included information from 17,951 randomly selected women screened with FFDM at 14 breast centres in the XBCSP, January-March 2014...

BACKGROUND: The study aimed to compare sex differences in the morphology and spatial orientation of pelvic acetabula to advance the understanding of hip anatomy. MATERIAL AND METHODS: The study was based on three-dimensional reconstructions of computed tomography images of 50 female and 50 male acetabula. The images were used for spatial analysis of hip acetabula relative to the base of the sacral bone as the plane of reference. Statistical analysis was performed to compare angles relevant to the actual axis of the acetabulum (inclination angle, anteversion angle, tilt angle) as well as the volume and inner surface area of the acetabulum...

Most frequent causes of androgenic manifestation are Cushing's syndrome, PCO, benign and malignant androgen-secreting non adrenal tumors and iatrogenic hirsutism. Hyperplasia or neoplasms of ectopic adrenocortical gland are rare. We report a case of a 63-year old female with hirsutism and alopecia. Laboratory data highlighted increased levels of androgens. Diagnostic imaging revealed normal morphology of adrenocortical gland and ovaries. In view of the clinical picture and suspected diagnosis of extra-adrenal cause, she underwent bilateral salpingo-oophorectomy...

Early detection of ovarian cancer is only achieved in around 20% of women due to lack of effective screening. We propose a method for surveillance of high risk women based on a microendoscope introduced transvaginally to image the fallopian tubes and ovaries. This requires extreme miniaturization of the optics and catheter sheath. We describe the design of a falloposcope that combines optical coherence tomography (OCT) and wide field imaging into a sub-1 mm diameter package. We characterize the systems and show that they provide contrast on ex-vivo samples of ovary and fallopian tube...
