Abstract
Compartment syndrome (CS) is a well-known surgical emergency with high morbidity including potential long-term disability and limb loss. The most important factor determining the degree of morbidity with CS is time to treatment; therefore, early diagnosis and surgery are vital. We present a patient who fell off his bicycle and sustained cervical spine fractures causing near complete quadriplegia. He was found by the road over 12 hours later, so his creatine phosphokinase (CPK) was trended and serial examinations were performed. We identified tight deltoid, trapezius, and latissimus compartments and brought him to the operating room for fasciotomies. Although lab values and compartment pressures can be helpful, they should not guide treatment. It is important to consider atypical sites for CS and complete a head to toe physical examination. Patients should proceed to the operating room if clinical suspicion exists for CS because of the morbidity associated with a missed diagnosis.

Abstract
Angiofibroma of the head and neck is classically found in the nasopharynx of an adolescent male. We present a rare case where an angiofibroma was diagnosed in the anterior nasal septum of a 51-year-old woman, the eighth nasal septal angiofibroma reported in a female. This case highlights how an angiofibroma in an older woman has a less vascular behaviour than one in an adolescent male, even though radiological enhancement may suggest that the lesion is highly vascularised. Nasal septal angiofibromas can be managed by biopsy and removed by simple endoscopic resection with minimal haemorrhage. Although very rare, extranasopharyngeal angiofibroma/nasal septal angiofibroma should be included in the differential diagnosis when patients of all ages present with nasal obstruction secondary to a nasal mass, with or without epistaxis.

Abstract
AIM To explore patient experiences of a structured exercise intervention for men with prostate cancer (PCa). SAMPLE 41 men with either localised or advanced PCa who had been referred for a structured exercise programme by their physician and then subsequently consented to a telephone survey. METHOD Participants underwent a 10-week supervised exercise programme within a large cancer centre hospital consisting of 8 sessions. They then completed a short multiple choice telephone survey, elaborating on their responses where appropriate. Views expressed by participants were analysed using an affinity diagram and common themes were identified. RESULTS Feedback from our telephone surveys was consistently positive and suggests that the structured exercise intervention provides exercise confidence, motivation to exercise, and social support and promotes positive health behaviour change in the context of exercise. Individual differences arose amongst participants in their perceived utility of the intervention, with 73.3% expressing a preference for structured exercise classes and 19.5% expressing a preference for exercising independently. CONCLUSION Design of a structured exercise intervention for patients with PCa should embrace the positive aspects outlined here but consider patients' individual differences. Ongoing feedback from patients should be utilised alongside traditional study designs to inform intervention design in this area.

Abstract
AIMS Silage is grass, preserved by fermentation and used as winter feed for cattle. The impact of a range of current grass silage preparation practices on the survival of Escherichia coli C600φ3538(Δvtx2 ::cat) and on the induction, release and infectivity of free phage were investigated. METHODS AND RESULTS Wilted and fresh grass samples, from plots with and without slurry application, were ensiled with or without formic acid. Each treatment combination was inoculated with approximately 6 log10 CFU per g E. coli C600φ3538(Δvtx2 ::cat) (donor strain) and E. coli C600::kanamycinR (recipient strain) in test-tube model silos and incubated in the dark at 15°C. The physico-chemical (pH, ammonia, ethanol, lactic acid and volatile fatty acids) and microbiological (total viable counts, TVC, total Enterobacteriaceae counts, TEC, E. coli counts, ECC and lactic acid bacteria, LAB) properties of each fermentation were monitored throughout the experiment as were the concentrations of E. coli C600φ3538(Δvtx2 ::cat), E. coli C600::kanamycinR , free phage and transductants, using culture and PCR-based methods. Over the course of the experiment the pH of the grass samples typically decreased by 2 pH units. TVC, TEC and ECC decreased by up to 2·3, 6·4 and 6·2 log10 CFU per g, respectively, while the LAB counts remained relatively stable at 5·2-7·1 log10 CFU per g. Both donor and recipient strains decreased by approximately 5 log10 CFU per g. Free phages were detected in all treatments and transductants were detected and confirmed by PCR in the silo containing wilted grass, pretreated with slurry and ensiled without formic acid. CONCLUSIONS Verocytotoxigenic E. coli may survive the ensiling process and the conditions encountered are sufficient to induce vtx2 bacteriophage leading to low levels of phage-mediated vtx2 gene transfer. SIGNIFICANCE AND IMPACT OF THE STUDY These studies suggest that the ensiling of grass may create an environment which facilitates the emergence of new verocytotoxigenic E. coli.

Abstract
BACKGROUND Exclusive Enteral Nutrition (EEN) induction in children with luminal Crohn's disease (CD) gives early mucosal healing (MH), but the long-term benefits of EEN-induced MH are just emerging. AIMS & METHODS We prospectively followed an Australian cohort of newly diagnosed children with predominantly luminal CD who completed at least six weeks EEN and with paired clinical Pediatric Crohn's Disease Activity Index (PCDAI), biochemical (C-reactive protein; CRP) and endoscopic assessment at diagnosis and post EEN. All commenced immunomodulators (IMs) early (<3 months from diagnosis) and had a minimum of 1 year follow-up. Complete MH was a simple endoscopic score for Crohn's disease (SES-CD) of 0, and SES-CD≥1 was ascribed to active endoscopic disease (aED) and further divided into near complete MH (SES 1-3), mild active disease (SES-CD 4-10) and moderate to severe disease (SES-CD>10). The primary outcome was long-term supervised sustained remission (SR) on IMs alone without need for corticosteroids, infliximab (IFX) or surgery. RESULTS A total of 54 eligible children (33 males) completing EEN induction were analysed. The median duration between pre and post EEN assessments was 60.5 days [interquartile range (IQR), 56-69.5]. Post EEN: clinical remission (PCDAI < 10) was observed in 45/54 (83%), and biochemical remission (PCDAI < 10 and CRP < 5 mg/dl) was observed in 39/54 (72%). Complete MH was observed in 18/54 (33%), near complete in 10/54(19%). SR was superior in those with complete MH vs. aED; 13/18, (72%) vs. 10/36 (28%), p = 0.003 at 1 year, 8/16, (50%) vs. 3/24, (8%), p = 0.008 at 2 years and (8/16, (50%) vs. 1/19, (6%), p = 0.005) at 3 years. Near-complete MH did not lead to superior SR. CONCLUSIONS Only complete MH post EEN induction predicts more favourable SR for up to 3 years.

Abstract
Verocytotoxigenic (vtx) Escherichia coli (VTEC) are zoonotic foodborne pathogens with the vtx operon encoded by lambdoid bacteriophage (phage). Despite much research on the host bacteria, similar data on the persistence of verocytotoxin converting phage and the ecological niches where transduction occurs are lacking and novel VTEC of important public health significance, have and continue to emerge. This study investigated the survival of a temperate vtx bacteriophage (24B ::kanamycinR ) in water (raw farm, pasteurized farm, laboratory tap and autoclaved purified water) and soil (sandy loam and loam soil). It also examined the persistence of an anti-VTEC lytic phage (e11/2) in the same matrices as this may be one option for controlling the emergence of novel VTEC, especially in farm ecological niches where other control options, such as chemical, heat or high pressure treatments, are not feasible. Samples inoculated with 24B ::kanamycinR and e11/2 bacteriophage (8 log10 pfu/ml or pfu/g) separately were incubated at 4°C and 14°C, representative Irish Winter and Summer temperatures, respectively, and tested every 2 days for 40 days. The transduction of 24B ::kanamycinR was also continuously assessed. Both phages survived with reductions observed, regardless of matrix or storage temperature. Moreover, 24B ::kanamycinR was able to transduce its host E. coli strain. It was therefore concluded that aquatic and soil environments on farms may serve as a vtx phage reservoir and transduction point but anti-VTEC phage is a possible biocontrol option.

Abstract
Liquid-crystalline polymers are materials of considerable scientific interest and technological value. An important subset of these materials exhibit rubber-like elasticity, combining the optical properties of liquid crystals with the mechanical properties of rubber. Moreover, they exhibit behaviour not seen in either type of material independently, and many of their properties depend crucially on the particular mesophase employed. Such stretchable liquid-crystalline polymers have previously been demonstrated in the nematic, chiral-nematic, and smectic mesophases. Here, we report the fabrication of a stretchable gel of blue phase I, which forms a self-assembled, three-dimensional photonic crystal that remains electro-optically switchable under a moderate applied voltage, and whose optical properties can be manipulated by an applied strain. We also find that, unlike its undistorted counterpart, a mechanically deformed blue phase exhibits a Pockels electro-optic effect, which sets out new theoretical challenges and possibilities for low-voltage electro-optic devices.

Abstract
Concentrations of nutrient nitrogen (N) and phosphorus (P) are elevated in rivers across large areas of Europe (European Nitrogen Assessment (ENA), Sutton et al., 2011). Environmental policies have been implemented over the past 20 years with the aim of reducing nitrogen inputs to surface waters. However, environmental and ecological status is still below set targets (ENA, Sutton et al., 2011). Identification of patterns in long-term change for nutrient trends in hydrological catchments in England & Wales is required to assess impacts of nutrient management policy and provide better evidence for future policy. Such information could provide essential evidence for supporting policy by combining information from the wider catchment, rather than relying on the analysis of data from individual sites. Surface water quality is subject to considerable spatial and short-period temporal variability, reflecting variability in loading and dilution. This makes it difficult to determine temporal trends at individual monitoring sites with relatively sparse sampling. Here we apply spatiotemporal statistical additive models for both nitrogen and phosphorus in river networks across England & Wales to investigate the overall pattern of nutrient concentrations in these river surface waters over the past 20-40 years. Concentrations of Orthophosphate (OP) have generally decreased over time for many of the Large Hydrological Areas with a seasonal pattern highlighting one peak in the summer months. Over the past ten years, Total Oxidised Nitrogen (Nitrate+Nitrite, TON) concentrations have generally been slowly decreasing or fairly constant. However, prior to 2000, concentrations were generally on an upward trend. The seasonal pattern highlights one trough in the summer months. The highest levels for OP and TON broadly occur in the same general areas across England & Wales. On average, over time, the lowest values are evident in the north-west and south-west (particularly for OP) and highest values are evident in the Midlands, Anglian and Southern regions.

Abstract
The management of the lateral neck in metastatic differentiated thyroid cancer (DTC) varies widely. Most groups advocate dissection of nodal levels II-IV but many perform a more extensive dissection. We aimed to asses whether there was any evidence for a modified radical neck dissection over a selective neck dissection by looking at the extent to which DTC metastases to levels I and V. We performed a review of the current literature including adult and paediatric patients who underwent a lateral neck dissection for metastatic DTC. The primary endpoint was histological confirmation of metastases in nodal levels I and V. 650 abstracts were identified and reviewed. 23 papers were included in the study. The incidence of level V metastases during routine level V dissection in patients with DTC is 20 % and the incidence of level I metastases during routine level I dissection in patients with DTC is 8 %. Histologically proven metastases were found in 22.5 % of level V neck dissection of which 2.5 % were pre-operatively suspected of metastases. 20 % had histologically proven metastases to level I of which 12 % were pre-operatively suspected of metastases. Our study has shown a 20 % incidence of level V metastases in the N+ neck suggesting that level V should be part of a planned neck dissection. Evidence is lacking for routine dissection of level I. A future prospective study is required to asses the question of risk factors for lateral nodal metastases, recurrence and survival.

Abstract
Concern has been expressed about the overuse of biocides in farm animal production and food industries. Biocide application can create selective pressures that lead to increased tolerance to one or more of these compounds and are concomitant with the emergence of cross-resistance to antibiotics. A triclosan sensitive Salmonella enterica serovar Typhimurium and the isogenic triclosan tolerant mutant were studied at the proteomic level in order to elucidate cellular mechanisms that facilitate biocide tolerance. 2-D differential fluorescent gel electrophoresis (DIGE) compared protein profiles of parent and mutant Salmonella, in the presence and absence of triclosan. Differentially expressed proteins were identified by mass spectrometry and divided into two groups: Group A describes proteins differentially expressed between susceptible and triclosan tolerant Salmonella and includes the known triclosan target FabI which contained a mutation at the triclosan target binding site. Group B identified proteins differentially expressed in response to triclosan exposure and defines a general cell defence network. Only four proteins were common to both groups highlighting the diverse range of pathways employed by Salmonella to counteract biocides. These data suggest that sub-lethal concentrations of triclosan induce discernible changes in the proteome of exposed Salmonella and provide insights into mechanisms of response and tolerance.

Abstract
Background: We have developed the Promoting Early Presentation (PEP) Intervention to equip older women with the knowledge, skills, confidence and motivation to present promptly with breast symptoms, and thereby improve survival from breast cancer. The PEP Intervention consists of a 10-min interaction between a radiographer and an older woman, supported by a booklet. Our previous report showed that at 1 year, the PEP intervention increased the proportion who were breast cancer aware compared with usual care. Methods: We randomised 867 women aged 67–70 years attending for their final routine appointment on the National Health Service Breast Screening Programme to receive the PEP Intervention, a booklet alone or usual care. The primary outcome was breast cancer awareness measured using a validated questionnaire asking about knowledge of breast cancer symptoms, knowledge that the risk of breast cancer increases with age and breast checking behaviour. Results: At 2 years, the PEP Intervention increased the proportion who were breast cancer aware compared with usual care (21 vs 6% odds ratio 8.1, 95% confidence interval 2.7–25.0). Conclusions: The uniquely large and sustained effect of the PEP Intervention on breast cancer awareness increases the likelihood that a woman will present promptly should she develop breast cancer symptoms up to many years later.

Abstract
CONTEXT Subclinical Cushing's syndrome has been described among diabetic populations in recent years, but no consensus has emerged about the value of screening. METHODS We enrolled 201 consecutive patients attending our diabetes clinic and 79 controls. Patients with at least two of the following three criteria were offered screening using a 2300 h salivary cortisol test: glycosylated hemoglobin of at least 7%, body mass index of at least 25 kg/m(2), and a history of hypertension or blood pressure of at least 140/90 mm Hg. Results are expressed as mean +/- sem. RESULTS Mean nighttime salivary cortisol levels were similar in the two groups (8.5 +/- 1.0 nmol/liter for diabetic patients vs. 5.8 +/- 1.0 nmol/liter for controls). Forty-seven patients (23%) had a value of at least 10 nmol/liter, which was set as a conservative threshold above which further investigation would be performed. Thirty-five (75%) agreed to further testing with a 1-mg overnight dexamethasone test. Of the remaining 12 patients, 10 were followed up clinically for at least 1 yr, and no evidence was found of the syndrome evolving. In 28 patients, serum cortisol suppressed to 60 nmol/liter or less. Of the seven patients who failed this test, four agreed to a 2 mg/d 48-h dexamethasone test, with serum cortisol suppressing to 60 nmol/liter or less in all four. Three declined this test but had normal 24-h urinary free cortisol levels. No patient had clinical features of hypercortisolism. CONCLUSIONS The 1-3% detection rates of three recently published series have not been realized at our center where we studied a group using criteria making patients more likely to have hypercortisolism. Our results do not support the validity of screening patients without clinical features of Cushing's syndrome in the diabetes clinic.

Abstract
An accurate knowledge of anatomy is a cornerstone of safe surgical intervention. Anatomy is therefore a key component of all stages of the Membership of the Royal College of Surgeons (MRCS) examinations. Partly for this reason, many trainees have traditionally spent a period of time attached to a university anatomy department relearning their anatomy and assisting in its teaching to undergraduate students.

Abstract
Background: It has been suggested that the known poorer survival from cancer in the United Kingdom, compared with other European countries, can be attributed to more advanced cancer stage at presentation. There is, therefore, a need to understand the diagnostic process, and to ascertain the risk factors for increased time to presentation. Methods: We report the results from two worldwide systematic reviews of the literature on patient-mediated and practitioner-mediated delays, identifying the factors that may influence these. Results: Across cancer sites, non-recognition of symptom seriousness is the main patient-mediated factor resulting in increased time to presentation. There is strong evidence of an association between older age and patient delay for breast cancer, between lower socio-economic status and delay for upper gastrointestinal and urological cancers and between lower education level and delay for breast and colorectal cancers. Fear of cancer is a contributor to delayed presentation, while sanctioning of help seeking by others can be a powerful mediator of reduced time to presentation. For practitioner delay, ‘misdiagnosis’ occurring either through treating patients symptomatically or relating symptoms to a health problem other than cancer, was an important theme across cancer sites. For some cancers, this could also be linked to inadequate patient examination, use of inappropriate tests or failing to follow-up negative or inconclusive test results. Conclusion: Having sought help for potential cancer symptoms, it is therefore important that practitioners recognise these symptoms, and examine, investigate and refer appropriately.

Abstract
BACKGROUND There is virtually no evidence for the effectiveness of interventions to promote early presentation in breast cancer. We aimed to test the efficacy of an intervention to equip older women with the knowledge, skills, confidence and motivation to detect symptoms and seek help promptly, with the aim of promoting early presentation with breast cancer symptoms. METHODS We randomised 867 women aged 67-70 years attending for their final routine appointment on the UK NHS Breast Screening Programme to receive: a scripted 10-min interaction with a radiographer plus a booklet, a booklet alone or usual care. The primary outcome was whether or not a woman was breast cancer aware based on knowledge of breast cancer symptoms and age-related risk, and reported breast checking. RESULTS At 1 month, the intervention increased the proportion who were breast cancer aware compared with usual care (interaction arm: 32.8% vs 4.1%; odds ratio (OR): 24.0, 95% confidence interval (CI): 7.7-73.7; booklet arm: 12.7% vs 4.1%; OR: 4.4, 95% CI: 1.6-12.0). At 1 year, the effects of the interaction plus booklet, and the booklet, on breast cancer awareness were largely sustained, although the interaction plus booklet remained much more effective. CONCLUSIONS An intervention to equip older women with the knowledge, skills, confidence and motivation to detect breast cancer symptoms and seek help promptly increases breast cancer awareness at 1 year. Future research will evaluate whether the intervention promotes early presentation and reduces breast cancer mortality.

Abstract
This article reviews the epidemiological evidence that the use of fenoterol leads to an increased risk of death compared with other commonly used β-agonist drugs such as salbutamol, and that fenoterol was a causative factor in the second epidemic of asthma deaths in New Zealand. One of the features of this evidence is the consistency of the findings. In addition to evidence from three case-control studies in New Zealand and a recent study in Canada, the fenoterol hypothesis is also consistent with data on time trends in mortality and drugs sales, and with a large body of experimental evidence that fenoterol has relatively greater cardiac side effects, and that these may be hazardous in the situation of hypoxia.

Abstract
On 27 December 2004, a giant gamma flare from the Soft Gamma-Ray Repeater 1806-20 saturated many satellite gamma-ray detectors, being the brightest transient event ever observed in the Galaxy. AMANDA-II was used to search for down-going muons indicative of high-energy gammas and/or neutrinos from this object. The data revealed no significant signal, so upper limits (at 90% C.L.) on the normalization constant were set: 0.05(0.5) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the gamma flux and 0.4(6.1) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the high-energy neutrino flux.

Abstract
AIM Careful monitoring of amiodarone is recommended because it produces a range of potentially severe adverse effects. The aim of this study was to compare existing practice at our hospitals with the current international guidelines for the use of this drug. METHODS A retrospective audit was carried out on all patients aged 15 years or older, with a primary discharge diagnosis of tachyarrhythmia and who were commenced and discharged alive on amiodarone between 1 January 2000 and 30 June 2002 from Wellington and Kenepuru Hospitals, Capital and Coast District Health Board, Wellington, New Zealand. The medical records were examined for baseline measurements of renal, liver, thyroid and pulmonary function, the electrocardiogram and chest X-ray. Follow-up arrangements were sought postdischarge. A questionnaire was sent to the general practitioner requesting information on follow-up testing. RESULTS During the trial period, 743 patients were admitted with a primary diagnosis of tachyarrhythmia. Eighty-six patients satisfied the entry criteria, and of these 58 were followed for at least 1 year postdischarge. Baseline testing of the electrocardiogram, full blood count and renal function testing was excellent (95-100%). Chest X-rays were carried out in 80% of patients. Baseline testing of thyroid (61%) and liver (44%) function was suboptimal. Two percent of patients had pulmonary function testing and no patient had a formal eye examination. At 6 months, only 32% had thyroid function tests and 41% had liver function tests. At 1 year, of those still on treatment, 35% had both liver and thyroid function tests. CONCLUSION Monitoring of thyroid, liver and pulmonary function tests in patients on amiodarone is less than ideal. This is probably because of lack of awareness of current guidelines.

Abstract
Riboflavin deficiency is common in many parts of the world, particularly in developing countries. The use of riboflavin-producing strains in the production of dairy products such as fermented milks, yogurts, and cheeses is feasible and economically attractive because it would decrease the costs involved during conventional vitamin fortification and satisfy consumer demands for healthier foods. The present study was conducted to assess in a rat bioassay the response of administration of milk fermented by modified Lactococcus lactis on the riboflavin status of deficient rats. Rats were fed a riboflavin-deficient diet during 21 d after which this same diet was supplemented with milk fermented by Lactoccus lactis pNZGBAH, a strain that overproduces riboflavin during fermentation. The novel fermented product, with increased levels of riboflavin, was able to eliminate most physiological manifestations of ariboflavinosis, such as stunted growth, elevated erythrocyte glutathione reductase activation coefficient values and hepatomegaly, that were observed using a riboflavin depletion-repletion model, whereas a product fermented with a nonriboflavin-producing strain did not show similar results. A safety assessment of this modified strain was performed by feeding rodents with the modified strain daily for 4 wk. This strain caused no detectable secondary effects. These results pave the way for analyzing the effect of similar riboflavin-overproducing lactic acid bacteria in human trials. The regular consumption of products with increased levels of riboflavin could help prevent deficiencies of this essential vitamin.

Abstract
Children born with severe homozygous protein C deficiency do not survive beyond the neonatal period unless they receive protein C replacement. Protein C concentrate (Baxter Biosciences, Vienna) is usually given intravenously via a central venous catheter The authors describe 2 children in whom protein C concentrate was successfully administered by subcutaneous infusion after they had had recurrent central line infections. Alternate daily doses of 250-350 IU/kg resulted in trough protein C levels of > 25 IU/dL. In the follow-up period of 1-2 years neither child has had a thrombotic episode or purpuric skin lesions, and infusions are managed in the home by their parents.

Abstract
PURPOSE To define the success of testis sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) in azoospermic men with a history of chemotherapy. PATIENTS AND METHODS In a retrospective study, 23 men with ejaculatory azoospermia and a history of chemotherapy underwent TESE in a search for usable spermatozoa. In six patients cryopreserved tissue and in nine patients fresh tissue provided sperm for an ICSI cycle. Histologic analysis of the testis was performed in all patients. The presence or absence of sperm, fertilization rates with ICSI, and final outcomes of pregnancy were recorded. RESULTS Spermatozoa were found on TESE in 15 (65.2%) of 23 men. On histopathology, the predominant pattern observed was Sertoli cell only (47.8%), followed by hypospermatogenesis (30.4%), mixed (17.4%), and late maturation arrest (4.3%). The fertilization rate was 65.2%, and ongoing/delivered pregnancies occurred in 30.8% of cycles. Six healthy boys and four healthy girls have been born to date. CONCLUSION Men who are azoospermic and have had prior cytotoxic therapy make up a small subgroup of males with nonobstructive azoospermia. It is important to define and characterize this subgroup and better define their true fertility potential. Approximately two thirds of these men have retrievable testis sperm, which may be used with ICSI to have healthy offspring. This exciting avenue for paternity has heretofore not been available to such patients.

Abstract
Syntactic and semantic processing of literal and idiomatic phrases were investigated with a priming procedure. In 3 experiments, participants named targets that were syntactically appropriate or inappropriate completions for semantically unrelated sentence contexts. Sentences ended with incomplete idioms (kick the...) and were biased for either a literal (ball) or an idiomatic (bucket) completion. Syntactically appropriate targets were named more quickly than inappropriate ones for both contextual biases, suggesting that syntactic analysis occurs for idioms. In a final experiment, targets were either concrete (expected) or abstract (unexpected) nouns. For literal sentences, the abstract targets were named more slowly than the concrete targets. In contrast, there was no concreteness effect for idiomatic sentences, suggesting that the literal meaning of the idiom is not processed. Overall, the results provide evidence for dissociation between syntactic and semantic processing.

Abstract
BACKGROUND Delayed presentation of symptomatic breast cancer of three months or more is associated with lower survival rates from the disease, yet 20% to 30% of women wait at least three months before consulting their general practitioner (GP) with breast symptoms. AIM To explore the factors that influence GP consultation by women with breast cancer symptoms. DESIGN OF STUDY Qualitative analysis of semi-structured interviews. SETTING Forty-six women with newly diagnosed breast cancer, selected from 185 women recruited to a larger study. METHOD Interviews were conducted eight weeks after diagnosis of breast cancer, comparing two groups of women divided according to the extent of delay between onset of symptoms and seeking medical care. Fifteen women had sought advice from their GP within two weeks of symptom discovery ('non-delayers' and 31 had waited 12 weeks or more before seeing their doctor ('delayers'). RESULTS Women with breast symptoms who presented promptly to GPs recognised the seriousness of the symptom they had discovered more quickly than delayers. Perception of seriousness was influenced by the nature of the initial symptom and how far it matched the individual's expectations of breast cancer as a painless breast lump. Other factors affecting help-seeking included attitudes to GP attendance, beliefs about the consequences of cancer treatment, and perceptions of other priorities taking precedence over personal health. CONCLUSIONS This analysis suggests that women need further information about the different types of breast cancer symptoms to assist symptom recognition, as well as encouragement to seek medical advice if a symptom is ambiguous. In addition, women may benefit from greater awareness of the benefits of early detection and reassurance about the improvements in quality of breast cancer care.

Abstract
Until today, nineteen trinucleotide repeat expansions larger than forty repeat copies have been found in the human genome. Of these, the CAG/CTG repeat is predominant motif with twelve loci identified, ten of which have been associated with the development of neurodegenerative diseases. We have developed a cloning approach which isolates disease genes containing trinucleotide repeat expansions. The method is based on size separation of genomic fragments, followed by subcloning and library hybridization with an oligonucleotide probe. Fractions and clones containing expanded repeats are identified by the repeat expansion detection (RED) method throughout the cloning procedure. Large family materials are not required and as little as 10 microg genomic DNA from a single individual is sufficient for this method. Using this strategy we have cloned two DNA fragments containing expanded repeats from two unrelated patients with a clinical diagnosis of cerebellar ataxia. Sequencing of the two fragments showed sequence identities with two disease genes, the Huntington gene and the ataxin 3 gene, respectively. The method should be adaptable to the cloning of any long repeat motif in any species. Furthermore the experimental steps can be performed in less than a month, making it very effective and time efficient to disease gene identification.

Abstract
A specification of the structural characteristics of the mental lexicon is a central goal in word recognition research. Of various word-level characteristics, semantics remains the most resistant to this endeavor. Although there are several theoretically distinct models of lexical semantics with fairly clear operational definitions (e.g., in terms of feature sharing, category membership, associations, or cooccurrences), attempts to empirically adjudicate between these different models have been scarce. In this paper, we present several experiments in which we examined the effects of semantic neighborhood size as defined by two models of lexical semantics--one that defines semantics in terms of associations, and another that defines it in terms of global co-occurrences. We present data that address the question of whether these measures can be fruitfully applied to examinations of lexical activation during visual word recognition. The findings demonstrate that semantic neighborhood can predict perforrmance on both lexical decision and word naming.

Abstract
Previous research has demonstrated that the language of older adults leads to denser representations in a high dimensional model of memory than does the language of younger adults (Conley & Burgess, in press), and thus that density in the model (HAL or the hyperspace analogue to language) may constitute a useful metric in comparing memory for younger and older adults. This paper extends the previous research by examining the role of density in semantic representations that emerged from the language generated by adults with Alzheimer' s and comparing the results with age-matched normal controls. We found that, just as older adults have denser representations in semantic space than do younger adults, adults with Alzheimer's have still denser representations than normal older adults. These results support the hypothesis that greater density, normally associated in the model with good semantic depth, may in fact reach a "saturation point" and affect retrieval in older adults and especially adults with Alzheimer's.
