Current margin practice and effect on re-excision rates following the publication of the SSO-ASTRO consensus and ABS consensus guidelines: a national prospective study of 2858 women undergoing breast-conserving therapy in the UK and Ireland.

Introduction: There is variation in margin policy for breast conserving therapy (BCT) in the UK and Ireland. In response to the Society of Surgical Oncology and American Society for Radiation Oncology (SSO-ASTRO) margin consensus ('no ink on tumour' for invasive and 2 mm for ductal carcinoma in situ [DCIS]) and the Association of Breast Surgery (ABS) consensus (1 mm for invasive and DCIS), we report on current margin practice and unit infrastructure in the UK and Ireland and describe how these factors impact on re-excision rates.

Methods: A trainee collaborative-led multicentre prospective study was conducted in the UK and Ireland between 1st February and 31st May 2016.

Shortness of breath, fever and abdominal pain in a 21-year-old student.

A 21-year-old patient presented with a 3-day history of shortness of breath, productive cough, fatigue, fevers and night sweats, associated with right upper quadrant pain. He had an appendicectomy 3 months previously. The CT images showed a right subphrenic collection, which was indenting the right lobe of the liver, with an appendicolith in the middle.

Anthropometric characteristics and mammographic parenchymal patterns in post-menopausal women: a population-based study in Northern Greece.

Objective: To examine the effects of various anthropometric determinants on mammographic patterns at postmenopausal ages, accounting for reproductive differences.

Methods: Mammograms from 900 post-menopausal women classified into high- (P2/DY) versus low-density (N1/P1) groups using the Wolfe criteria were associated with changes in body figure, reported and measured height and weight, body mass index, hip, waist and chest circumferences, chest/hip ratio, waist/hip ratio (WHR), breast size, and leg length. Reproductive factors included ages at menarche, first pregnancy and menopause, years since menopause, parity, and breast feeding duration.

Correlates of high-density mammographic parenchymal patterns by menopausal status in a rural population in Northern Greece.

Reproductive factors affect breast cancer risk, but less is known of their associations with mammographic density and whether these differ by menopausal status. We report on a cross-sectional study of 1946 pre- and 3047 post-menopausal women who joined a breast screening programme in Northern Greece during 1993-1997. The odds of having a high-density Wolfe pattern (P2/DY) was inversely associated with age (P for linear trend <0.

Doctors' confusion over ratios and percentages in drug solutions: the case for standard labelling.

The different ways of expressing concentrations of drugs in solution, as ratios or percentages or mass per unit volume, are a potential cause of confusion that may contribute to dose errors. To assess doctors' understanding of what they signify, all active subscribers to doctors.net.
