Abstract
The vicinity of an ancient abandoned copper mine located on the Isle of Anglesey was assessed for the dispersion of copper, zinc, lead, and cadmium into the surrounding environment. Extraction of soil, lichens, cattle feces, and Calluna vulgaris L. (ling) tissue, using aqua regia, was carried out and together with water samples, these were analyzed using flame atomic absorption spectroscopy. Atmospheric dispersion and dilution was plotted from the workings to the coast and the resultant dilution ascertained. Evidence of bioaccumulation by plants and animals is presented and partitioning within plants highlighted. The results suggest that atmospheric dispersion has ceased but residual metal concentrations in the soil remain persistent and could present health hazards to animals and humans in the past and in the future.

Abstract
Valproate (VPA), one of the mood stabilizers and antiepileptic drugs, was recently found to inhibit histone deacetylases (HDAC). Increasing reports demonstrate that VPA has neurotrophic effects in diverse cell types including midbrain dopaminergic (DA) neurons. However, the origin and nature of the mediator of the neurotrophic effects are unclear. We have previously demonstrated that VPA prolongs the survival of midbrain DA neurons in lipopolysaccharide (LPS)-treated neuron-glia cultures through the inhibition of the release of pro-inflammatory factors from microglia. In this study, we report that VPA upregulates the expression of neurotrophic factors, including glial cell line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic factor (BDNF) from astrocytes and these effects may play a major role in mediating VPA-induced neurotrophic effects on DA neurons. Moreover, VPA pretreatment protects midbrain DA neurons from LPS or 1-methyl-4-phenylpyridinium (MPP+)-induced neurotoxicity. Our study identifies astrocyte as a novel target for VPA to induce neurotrophic and neuroprotective actions in rat midbrain and shows a potential new role of cellular interactions between DA neurons and astrocytes. The neurotrophic and neuroprotective effects of VPA also suggest a utility of this drug for treating neurodegenerative disorders including Parkinson's disease. Moreover, the neurotrophic effects of VPA may contribute to the therapeutic action of this drug in treating bipolar mood disorder that involves a loss of neurons and glia in discrete brain areas.

Abstract
OBJECTIVES To determine the incidence and characteristics of pediatric patients with central nervous system (CNS) germ cell tumors (GCT) in Canada. METHOD A national retrospective review of hospital charts was done on all patients with CNS GCT diagnosed between 1990 and 2004. Patients had to be under age 18 years at the time of diagnosis of a CNS germ cell tumor and be a resident of Canada. Information extracted included age and year of diagnosis, pathological diagnosis, location of tumor, evidence of disseminated disease at time of diagnosis and biological markers. RESULTS One hundred and twenty-one cases were identified (83 germinoma; 38 non-germinoma germ cell tumor). The mean annual incidence of CNS GCT was 1.06 per million children (0.7 per million for germinoma; 0.3 per million for NGGCT). Though yearly incidences varied, there was no clear trend to increased incidence. Male predominance was noted (2.4:1 for germinoma; 11:1 for NGGCT). The primary locations were the pineal and suprasellar regions. At the time of diagnosis, disseminated disease was not uncommon (22% germinoma; 32% NGGCT). Beta human gonadotrophin was elevated in the serum, cerebrospinal fluid (CSF) or both in 7% of patients with germinoma and 36% of patients with NGGCT. Elevation of alpha-fetoprotein in serum, CSF or both was seen in 34% of patients with NGGCT. CONCLUSION The incidence of CNS germ cell tumors in Canadian children is similar to that observed in other Western countries.

Abstract
Alzheimer disease is a progressive degenerative disorder of the brain characterized by a slow, progressive decline in cognitive function and behavior. As the disease advances, persons with Alzheimer disease have tough time with daily usage of things like using the phone, cooking, handling money, or driving the car. The disease is more common in elder population. It is estimated that Alzheimer disease affects 15 million people worldwide and approximately 4 million Americans. The clinical features of Alzheimer disease overlaps with common signs of aging, and other types of dementia, hence the diagnosis remains difficult. The neuropathologic hallmarks of the disorder are amyloid-rich senile plaques, neurofibrillary tangles, and neuronal degeneration. Drugs approved for treating Alzheimer disease include acetylcholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonist. Caregivers not getting adequate information about Alzheimer disease may believe that nothing can be done to manage its symptoms. Understanding the extent of Alzheimer disease related knowledge can assist disease management that result in improved disease management and reduced care costs. This article attempts to focus on some of the important recent developments in understanding and management of Alzheimer disease.

Abstract
This study compared genetic nurse counsellors with standard services for breast cancer genetic risk counselling services in two regional genetics centres, in Grampian region, North East Scotland and in Cardiff, Wales. Women referred for genetic counselling were randomised to an initial genetic counselling appointment with either a genetic nurse counsellor (intervention) or a clinical geneticist (current service, control). Participants completed postal questionnaires before, immediately after the counselling episode and 6 months later to assess anxiety, general health status, perceived risk and satisfaction. A parallel economic evaluation explored factors influencing cost-effectiveness. The two concurrent randomised controlled equivalence trials were conducted and analysed separately. In the Grampian trial, 289 patients (193 intervention, 96 control) and in the Wales trial 297 patients (197 intervention and 100 control) returned a baseline questionnaire and attended their appointment. Analysis suggested at least likely equivalence in anxiety (the primary outcome) between the two arms of the trials. The cost per counselling episode was 11.54 UK pounds less for nurse-based care in the Grampian trial and 12.50 UK pounds more for nurse-based care in Cardiff. The costs were sensitive to the grade of doctor (notionally) replaced and the extent of consultant supervision required by the nurse. In conclusion, care based on genetic nurse counsellors was not significantly different from conventional cancer genetic services in both trial locations.

Abstract
6121 Background: In 2002, Kansas City Cancer Center (KCCC) performed a quality improvement (QI) project to evaluate how breast cancer patients were being assessed for family history and cancer risk management. A self-administered family history questionnaire was developed to improve the thoroughness of family history collected and education of clinicians was completed to improve the recognition of risk factors based on ASCO guidelines. Methods: Chart audits on 210 women with breast cancer at KCCC, were completed in the second quarter of 2005. All patients were under the age of 65, not undergoing chemotherapy. A risk management tool was developed. Scoring criteria for 2002 was replicated in 2005 as listed in the table . Results: In 2002, 171 pts (89%) had level 1 or 2 family history assessed compared to 207 pts (99%) in 2005, p<0.0001. In 2002, 47% had 3 generations assessed compared to 84% in 2005, p<0.0001. In 2002 and 2005, some risk factor management occurred in both groups, and was equal, 78% and 80% respectively (p=ns). Of those that had risk management 33% had level 1 in 2002 compared to 3% in 2005 (p<0.0001) a 91% reduction in identifying risk without subsequent management. In 2002, 58% had level 2, compared to 71% in 2005 (p=0.02) a 23% improvement in identification & management of risk. In 2002, 9% had level 3 compared to 26% in 2005 (p<0.0001) a 183% improvement in patients with a detailed risk assessment and/or genetic referral. Conclusions: By improving the assessment of family history and education of providers, women with breast cancer are receiving more information to reduce their risk for recurrence and complications. Patients who were identified as high risk for BRCA1 or BRCA2 mutations were referred to either a nurse practitioner or genetic counselor.

Abstract
9053 Background: Carboplatin based regimens are widely used in the treatment of unresectable pediatric LGG. Carboplatin hypersensitivity reaction (CHSR) represents a main limiting factor. Objective: To analyse the incidence, characteristics, management and impact on outcome of CHSR. Methods: National retrospective review of children diagnosed with LGG between 1988 and 2004. Inclusion criteria were age <18 years, pathology proven diagnosis of LGG except in NF1 patients, and no chemotherapy or radiotherapy prior to carboplatin chemotherapy. Results: 105 patients (61F/44M) from 10 Canadian centers were included in the study. Median age at diagnosis was 3.5y (0.3–16.8). 33 patients had NF1, 75 had diencephalic tumor. Carboplatin was given monthly or weekly respectively in 46 and 59 patients. 44 (41.9%) patients developed carboplatin HSR at a median time of 6.5 months (0.4–15.4), after a median number of 10.5 (3–39) injections. CHSR occurred significantly earlier with the weekly schedule (p=0.016). Cumulative incidence of CHSR increased with the number of injections with no plateau. Female had significant higher risk to develop CHSR (p=0.02) whereas age, NF1 status and schedule of administration were not significant risk factors. First allergic reaction was rated grade I, II in 36 patients (82%). 34 patients were reexposed to carboplatin with desensitization/premedication, allowing 14 patients (41.2%) to complete their treatment. But the majority (58.8%) had recurrent allergic reaction with a significant worsening of their symptoms (p=0.039). The median number of additional Carboplatin injections delivered was 4 (0.5–34). After Carboplatin discontinuation, 18 patients were switched to another chemotherapy regimen. 5 years PFS was not significantly different in allergic and non allergic patients (53.9% and 45.6%). Conclusions: In our experience, the incidence of CHSR is high (41.9%). Female have higher risk of CHSR. Desensitization/premedication has limited efficacy and does not prevent worsening of CHSR. CHSR did not impact the PFS. However many patients did switch to another chemotherapy regimen and the total duration of treatment was comparable in both groups. No significant financial relationships to disclose.

Abstract
Unregulated microglial activation has been implicated as a pivotal factor contributing to Parkinson's disease. Using mesencephalic neuron-glia cultures, we address the novel possibility that peptides endogenous to the substantia nigra (SN), substance P and dynorphin (10(-13)-10(-14) M), are opposing mediators of microglial activation and consequent DA neurotoxicity. Here, we identify that substance P (10(-13)-10(-14) M) is selectively toxic to DA neurons in a microglia-dependent manner. Mechanistically, substance P (10(-13)-10(-14) M) activated microglial NADPH oxidase to produce extracellular superoxide and intracellular reactive oxygen species (ROS). Neuron-glia cultures from mice lacking a functional NADPH oxidase complex (PHOX-/-) were insensitive to substance P (10(-13)-10(-14) M) -induced loss of DA neuron function. Mixed glia cultures from (PHOX-/-) mice failed to show a significant increase in intracellular ROS in response to substance P compared with control cultures (PHOX+/+). Further, dynorphin (10(-14) M) inhibited substance P (10(-13) M) -induced loss of [3H] DA uptake. Here we demonstrate a tightly regulated mechanism governing microglia-derived oxidative stress, where the neuropeptide balance of dynorphin and substance P is critical to DA neuron survival.

Abstract
Depression in patients with end-state renal disease (ESRD) is both underdiagnosed and treated, which may contribute to an increase in morbidity and mortality. Efforts aimed at screening, diagnosing, and treating depression could potentially modify outcomes in this population. The purpose of this study was to compare the prevalence of depression, as measured by the Beck Depression Inventory (BDI-II), the primary nurse, and nephrology team, among a cohort of patients receiving chronic hemodialysis (HD). A secondary objective was to identify patient variables associated with depression. Patients were screened for depression at the same time point, using the BDI-II, the primary nurse and the nephrology team. Depression was defined as a BDI-II score > or =14. Agreement between the BDI-II score, nurse, and nephrology team assessment of depression was compared using a kappa score and receiver-operating characteristic (ROC) curves were generated. One hundred and twenty-four of an eligible 154 patients completed the study. Depression as measured by a BDI-II> or =14, the nurse and the team was diagnosed in 38.7%, 41.9%, and 24.2% of patients, respectively. With the BDI-II as the gold standard, the nurses' diagnosis of depression had an agreement of 74.6% vs. only 24.2% agreement with the nephrology team. A previous history of malignancy was the only variable associated with the diagnosis of depression. Depression is common among patients on HD, supporting the need for a routine depression-screening program. The primary dialysis nurse is in a key position to identify patients with depression and should be considered as an integral part of the nephrology team.

Abstract
OBJECTIVES To determine whether a fiberoptic Raman system, suitable for in vivo use, is able to differentiate between benign and malignant bladder and prostate pathologic findings in vitro. Raman spectroscopy is an optical technique that provides a measure of the molecular composition of tissue by analyzing the way that tissue scatters laser light. Laboratory studies have shown that the technique can be used to identify and characterize transitional cell carcinoma and prostate adenocarcinoma in vitro. METHODS A total of 220 Raman spectra were recorded from 29 snap-frozen bladder samples collected at cystoscopic procedures, and 197 Raman spectra were recorded from 38 snap-frozen prostate samples collected at transurethral resection of the prostate. The spectra were correlated with the histologic features and used to construct separate diagnostic algorithms for the bladder and prostate. These algorithms were tested as to their ability to determine the pathologic finding of a sample from its Raman spectrum. RESULTS The bladder algorithm was able to differentiate benign samples (normal and cystitis) from malignant samples (transitional cell carcinoma), with an overall accuracy of 84%. The prostate algorithm was able to differentiate benign samples (benign prostatic hyperplasia and prostatitis) from malignant samples (prostate cancer), with an overall accuracy of 86%. CONCLUSIONS The results of this study have demonstrated that the clinical Raman system can provide an accurate and objective method to diagnose prostate and bladder cancer in vitro. Because the Raman probe is suitable for use during endoscopic, laparoscopic, or open procedures, this work paves the way for in vivo studies.

Abstract
This case study describes a multi-disciplinary investigation of the emergence from coma of an 80-year old female (KE) following severe traumatic brain injury. The relationship between cognitive/behavioural ability and the integrity of cerebral function was assessed using neuropsychological measures, positron emission tomography, electroencephalography, somatosensory evoked potentials and trans-cranial magnetic stimulation. These investigations were performed as KE was beginning to emerge from coma (4 weeks) and, again, approximately 1 year following brain injury, when she was judged to have achieved her maximum level of recovery. Neuropsychological measures revealed improvement during the first year post-injury in KE's speed of information processing, memory and executive abilities. Electrophysiological and metabolic studies indicated a restoration of functional integrity that was consistent with the gradual recovery in higher brain function documented using behavioural procedures. This case study demonstrates the rehabilitation potential of pre-morbidly healthy older adults following severe traumatic brain injury.

Abstract
A disturbingly high prevalence of single or bilateral lower extremity amputations in our program prompted us to conduct a study to identify the prevalence of risk factors that predispose patients on hemodialysis (HD) to foot problems. The study consisted of a one-time assessment of subjects' risk for and actual prevalence of amputation. The sample consisted of 232 subjects--56% male, 44% female. Ages ranged from 21-91 years, mean age 65.1 and median age 69 years. The most common comorbidities were hypertension (75%), coronary artery disease (50%), diabetes (42.2%), hyperlipidemia (34.9%), and peripheral vascular disease (27.2%), which are all established risk factors for peripheral arterial occlusive disease. Twenty-one percent of subjects were current smokers; 28% were former smokers. Nearly 13.4% of subjects had undergone amputations ranging from single toes to bilateral above knee amputations. Only 31% of subjects had both bilateral palpable pedal pulses present. Neuropathy, as evidenced by the inability to feel the application of monofilaments to 10 sites on each foot or the presence of symptoms, was present in 74.6% of subjects. Only 2.6% of subjects demonstrated comprehensive self-care behaviors (SCBs). With respect to subjects' ability for self-care, 75% of subjects had adequate vision, 60% adequate dexterity, and 55% adequate flexibility to perform self-care. Study findings confirmed impressions that patients are at considerable risk for foot complications. Implications for nursing practice include regular foot assessment, education for self-care, and referral to specialists when required.

Abstract
The antimicrobial activity of extracts of Curcuma zedoaria and Curcuma malabarica tubers was tested against six bacterial and two fungal strains using the agar well diffusion and broth dilution methods. Petroleum ether, hexane, chloroform, acetone and ethanol extracts exhibited antibacterial as well as antifungal activity. Acetone and hexane extracts of both tubers showed comparable antimicrobial activity as indicated by minimum inhibitory concentration (MIC) values, but other extracts of Curcuma malabarica showed significantly lower activity than those of Curcuma zedoaria. The MIC values for different strains and extracts ranged from 0.01 to 0.15 mg/ml in Curcuma zedoaria and from 0.01 to 0.94 mg/ml in Curcuma malabarica. Staphylococcus aureus (Gram positive) was inhibited by Curcuma malabarica but not by Curcuma zedoaria. This study is the first report of the antimicrobial properties of Curcuma malabarica. The findings also support the use of Curcuma zedoaria tubers in traditional medicine for the treatment of bacterial and fungal infections.
