Dyshomeostasis of copper and zinc is linked to neurodegeneration. This study investigated the relationship between circulating copper and zinc and copper/zinc ratios and cognitive function, symptoms of depression and anxiety, and neurotrophic factors in older Australian adults. In this cross-sectional study ( = 139), plasma copper, serum zinc, and neurotrophic factors (brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor, and insulin-like growth factor-1) were assessed.

A palpable abnormality of the breast was found in three women, one aged 57 and two aged 41. The first two patients predominantly showed the characteristics of a purulent inflammation, and on mammogram the third patient appeared to have mastitis carcinomatosa. Histopathological investigation revealed a lobular, non-caseating granulomatous inflammation.

Cervical intraepithelial neoplasia (CIN I, II, and III) and cases of CIN III associated with micro-invasive cervical carcinoma (CIN III & mCA) were analysed for evidence of episomal or integrated human papillomavirus (HPV) 16/18 DNA by fluorescence in situ hybridization (FISH). In parallel, numerical aberrations of chromosomes 1, 17, and X were determined in these lesions as indicators of genomic instability. HPV 16/18 DNA was present in 2 of 12 CIN I, 19 of 23 CIN II/III, and 10 of 12 CIN III & mCA.

The frequency of high-risk human papillomavirus (hr-HPV) genotypes in patients with adenocarcinoma in situ (ACIS) with coexisting cervical intraepithelial neoplasia (CIN), ACIS without coexisting CIN, and high-grade CIN (CIN II/III) was studied, in order to gain more insight into the relation between hr-HPV infections and the development of coexisting squamous and glandular lesions. The SPF(10) LiPA PCR was used to detect simultaneously 25 different HPV genotypes in biopsies obtained from 90 patients with CIN II/III, 47 patients with ACIS without coexisting CIN, and 49 patients with ACIS and coexisting CIN. hr-HPV was detected in 84 patients (93%) with CIN II/III, 38 patients (81%) with ACIS without CIN, and in 47 patients (96%) with ACIS and coexisting CIN.

Objective: To assess interobserver variation in the diagnosis of thick tissue specimens (microbiopsies) in cytology smears and histologic sections taken from them, to evaluate the applicability of MIB-1 in histologic sections from microbiopsies and to evaluate whether processing microbiopsies in inconclusive smears has additional diagnostic value.

Study Design: Cytologic smears were selected in which there were diagnostic disagreements between pathologists and cytologists and microbiopsies were present. Interobserver variation among three pathologists and three cytologists in the diagnosis of these microbiopsies was investigated.

We analyzed the value in cervical cytology of a recently developed technique by which it is possible to remove thick tissue specimens, called microbiopsies, from cervical smears and to process them for histologic examination. In 12 (48%) of 25 cervical smears in which microbiopsies were found, the histologic sections from them confirmed the cytologic diagnosis. Most cases involved classification of lesions diagnosed as cervical intraepithelial neoplasia.

Background: Based on earlier observations that the thickness of the intima and structure of the media may have an impact on the long-term patency of arterial conduits and the lack of detailed histologic studies of the right gastroepiploic and inferior epigastric arteries, we subjected both vessels to morphometric analysis with emphasis on their suitability as conduits in myocardial revascularization.

Methods: The right gastroepiploic and inferior epigastric arteries were harvested from 28 unselected individuals (mean age, 73.2 years) at autopsy, and the luminal diameter and the width of the intima and media were measured.

Recent case-referent studies in the Nijmegen breast-screening programme have shown a reduction in breast-cancer mortality of approximately 50% due to screening of women aged 65 years and older. In this type of study, however, the results may be biased because of self-selection. The purpose of our present study was to compare the breast-cancer mortality rate in a population invited for screening with that of a reference population from an area without a screening programme.

The use of mammography in recent years has resulted in an increase in the detection of small breast cancers. The beneficial effects of early detection on breast cancer mortality seem to differ with age. To obtain more insight into this matter we studied the long-term prognosis of patients with early invasive breast cancers (T1) in three age groups: 144 patients of age 40-49, 402 patients of age 50-69 and 192 patients 70 years or older at diagnosis.

Background: Only a few small studies have been conducted to examine the usefulness of mammographic screening in elderly women. These studies suggest that the screening-related reduction in breast cancer mortality rates is less than the estimated 20%-40% reduction observed for women aged 50-70 years at the time of their first screening.

Purpose: We have studied the efficacy of continued mammographic screening for breast cancer of elderly women within our screening program.
