To identify risk factors in the development of arm edema (AE) after conservative management breast cancer, authors prospectively measured differences upper and lower circumference 282 patients with stage I or II cancer who received radiation. AE was defined as a difference 2.5 cm more either measurement between treated untreated arms. Median follow-up 37 months (range, 7-109 months). The crude frequency overall 19.5% (55 patients). In 21 (7.4%) transient; 34 (12.1%) had persistent AE, which...

Instability of a CAG repeat in 4p16.3 has been found Huntington's disease (HD) chromosomes. Unlike similar the fragile X syndrome, expanded HD showed no evidence somatic instability comparison blood, lymphoblast, and brain DNA from same persons. Four pairs monozygotic twins displayed identical lengths suggesting that size is determined gametogenesis. In contrast with syndrome tissue, mosaicism was readily detected as diffuse spread sperm samples. Typically, modal larger than corresponding...

To evaluate quantitative measures of eye movements as possible biomarkers in prediagnostic and early stages Huntington disease (HD).The study sample (n = 215) included individuals both at risk recently diagnosed with HD. All participants completed a uniform clinical evaluation which administration the Unified Huntington's Disease Rating Scale (UHDRS) by movement disorder neurologist molecular testing to determine HD gene status. A high resolution, video-based tracking system was employed...

Background: Because of the growing demand for genetic assessment, there is an urgent need information about what services are appropriate women with a family history breast cancer. Our purpose was to compare psychologic impact and costs multidisciplinary surgical assessment service those current provisions. Methods: We carried out prospective randomized trial consultation (the group) without control in 1000 All P values from two-sided tests. Results: Although statistically significantly...

Breast cancer is a rare condition in males. There dearth of information about the psychological and social impact this condition. Data from six in-depth interviews with men who had breast identified seven major issues. These were associated delay diagnosis, shock, stigma, body image, causal factors, provision emotional support. The findings small study suggest that there are factors for diagnosed which have implications their care management. recommendations arising development structured...

This study compared genetic nurse counsellors with standard services for breast cancer risk counselling in two regional genetics centres, Grampian region, North East Scotland and Cardiff, Wales. Women referred were randomised to an initial appointment either a counsellor (intervention) or clinical geneticist (current service, control). Participants completed postal questionnaires before, immediately after the episode 6 months later assess anxiety, general health status, perceived...

They examined because they had either isolated sporadic or familial aniridia, aniridia one more of the WAGR (Wilms9 tumour, genital anomalies, and mental retardation) syndrome anomalies.

There is considerable interest in assessing patients with Marfan syndrome at the clinical, protein, and genetic levels. Clinical assessments are inconsistent between centres clinicians. no satisfactory clinical grading scales against which to analyse molecular information, limiting scope of clinical/ correlations. We present for major systems involved suggest that their widespread use will facilitate collaborative approaches correlations international therapy.

Individuals undergoing cancer genetic risk assessment have been found to a poor understanding of the process, which may affect how well they cope with learning their risk. This paper reports free‐text data from questionnaires completed by women randomised controlled trial psychological intervention.

Summary Fourteen patients with Marfan syndrome, defined according to present criteria, had bone mineral content of the distal forearm measured by single photon absorptiometry. Patients were matched for age and sex a large local group healthy volunteers. While further work is needed other methods densitometry measurements at sites, our results provide no evidence that there an increased incidence osteoporosis in syndrome.

Most UK genetics centres offering predictive testing for hereditary non‐polyposis colorectal cancer (HNPCC) use an extended counselling protocol originally developed Huntington's disease. Shortened may be more appropriate in the context of treatable genetic conditions such as HNPCC. Twenty‐six high‐risk individuals were randomized to (two sessions education and reflection held 1 month apart) or shortened (a single educational session) prior HNPCC testing. Prospective questionnaires,...
