OBJECTIVE: The presence of ectopic or supernumerary breast tissue is a rare event, related to a not complete regression of breast tissue along the milk line. Primary ectopic breast cancer of the axilla can create many difficulties in differential diagnosis with subsequent delayed specific treatments. The incidence of ectopic breast tissue is 0.2-6%, and the axilla is the most common site involved. In this tissue, the same physiologic and pathologic changes as seen in ectopic breast tissue may occur, including carcinoma formation...

BACKGROUND: Vascular risk factors (VRF) in multiple sclerosis (MS) patients have been associated with lower brain volumes. It is currently unknown if this association already exists in early MS and how it develops over time. METHODS: We identified 82 patients with clinically isolated syndrome (CIS) ( n = 61) or with early relapsing-remitting MS ( n = 21) and assessed their VRF including arterial hypertension, hyperlipidaemia, diabetes mellitus and smoking. We analysed T2-lesion load, normalized brain volume (NBV), cortical grey (cGMV) and white matter volumes (WMV), thalamic and basal ganglia volumes at baseline and follow-up magnetic resonance imaging (MRI) and assessed the percentage of brain volume change (PBVC) using SIENA...

Isthmocele appears as a fluid pouch-like defect in the anterior uterine wall at the site of a prior Cesarean section and ranges in prevalence from 19% to 84%, a direct relation to the increase in Cesarean sections performed worldwide. Many definitions have been suggested for the dehiscence resulting from Cesarean section, and we propose standardization with a single term for all cases: isthmocele. Patients are not always symptomatic, but symptoms typically include intermittent abnormal bleeding, pain, and infertility...

While lung cancer is the second most diagnosed form of cancer in men and women, a sufficiently early diagnosis can be pivotal in patient survival rates. Imaging-based, or radiomics-driven, detection methods have been developed to aid diagnosticians, but largely rely on hand-crafted features that may not fully encapsulate the differences between cancerous and healthy tissue. Recently, the concept of discovery radiomics was introduced, where custom abstract features are discovered from readily available imaging data...

BACKGROUND: Autism spectrum disorder (ASD) is diagnosed more frequently in boys than girls, even when girls are equally symptomatic. Cutting-edge behavioral imaging has detected "camouflaging" in girls with ASD, wherein social behaviors appear superficially typical, complicating diagnosis. The present study explores a new kind of camouflage based on language differences. Pauses during conversation can be filled with words like UM or UH, but research suggests that these two words are pragmatically distinct (e...

Background: Negative body image can result in sexual dysfunction for both women and men. Drive for thinness, drive for muscularity and drive for leanness have all been associated with poor body image. However, research to date has not examined which is the strongest predictor of sexual problems in each gender. Methods: The present study used measures of drive for muscularity and drive for thinness simultaneously to predict sexual functioning in both genders. Participants (n=519) completed measures of drive for thinness, drive for muscularity, sexual esteem, sexual assertiveness, discomfort exposing their bodies during sex and genital satisfaction...

Many studies have investigated the influence of emotion on memory processes across the human lifespan. Some results have shown older adults (OA) performing better with positive stimuli, some with negative items, whereas some found no impact of emotional valence. Here we tested, in two independent studies, how younger adults (YA) and OA would perform in a visuospatial working memory (VSWM) task with positive, negative, and neutral images. The task consisted of identifying the new location of a stimulus in a crescent set of identical stimuli presented in different locations in a touch-screen monitor...
