ABSTRACT

INTRODUCTION: Between 16,000 and 48,000 women are estimated to present to UK breast clinics with nipple discharge each year. The incidence of malignancy in these women is 2.7-24.2%. Currently, there is no consensus on the best way to investigate and manage these women. The aim of this study was to assess the rate of malignancy in women presenting with unilateral nipple discharge, and to evaluate the role of examination, imaging and cytology in reliably predicting outcome. METHODS: Breast units were asked to prospectively collect data on all new patients with unilateral nipple discharge. Data collected included discharge colour, whether it was uniductal or multiductal, examination and imaging findings, cytology results and outcome. RESULTS: Complete datasets were submitted by 5 units on 228 patients. The incidence of malignancy was 4.4%. Clinical examination was valuable in detecting malignancy and multiductal discharge was not related to malignancy. The positive predictive value for detecting malignancy for an abnormality found on mammography was 53.5% and for ultrasonography, it was 65.2%. The role of cytology in detecting malignancy was inconclusive with positive predictive values of the presence of red blood cells and epithelial cells at 6.1% and 10.7% respectively. CONCLUSIONS: A large number of women are investigated for nipple discharge (with huge resource implications) but there is little reliable evidence on the best way to investigate and manage these patients. A larger study is needed to evaluate the role of investigations in nipple discharge to produce guidelines on optimal management.

ABSTRACT

To determine the relative importance of various factors in the causation of wasting related to human immunodeficiency virus (HIV), quantitative analysis and linear structural modeling was performed on energy metabolism data collected longitudinally and prospectively from 33 men positive for the human immunodeficiency virus at 105 time points over a 3-y period before the era of highly active antiretroviral therapy. Measured variables included energy intake, total energy expenditure, resting energy expenditure, rate of change in weight, CD4 count, clinical status, appetite, and mood. Derived variables included energy balance, activity-related energy expenditure, and physical activity level. Relative contributions were assessed by linear structural modeling based on multiple regression expressing results as path coefficients for individual relationships. The primary determinant of energy balance was energy intake (r = 0.80). Total energy expenditure made a very minor contribution to energy balance (r = -0.04). Total energy expenditure was primarily determined by activity level (r = 0.91), which itself was negatively related to the presence of opportunistic infection and CD4 count. Energy intake was related to activity level (r = 0.28) and appetite (r = 0.30), which were closely interrelated (r = 0.59). Such linear structural models allow quantitative importance to be apportioned to factors determining weight change in those infected with HIV and represent a powerful tool for future metabolic studies.
