Abstract
BACKGROUND There is little evidence to guide the commissioning of residential provision for adults with autistic spectrum disorder (ASD) in the UK. We aim to explore the degree and impact of diagnostic congregation among adults with intellectual disabilities (ID) and ASD living in staffed housing. METHODS One hundred and fifty-seven adults with intellectual disabilities from a sample of 424 in staffed housing were assessed as having the triad of impairments characteristic of ASD. They lived in 88 houses: 26 were non-congregate (40% or fewer residents had the triad) and 50 congregate (60% or more had the triad); 12 with intermediate groupings were eliminated. Non-congregate and congregate groups were compared on age, gender, adaptive and challenging behaviour, house size, staff per resident and various measures of quality of care and quality of outcome. Comparisons were repeated for Adaptive Behavior Scale (ABS)-matched, congregate and non-congregate subsamples. RESULTS Non-congregate settings were larger, had lower staff per resident and more individualised social milieus. Groups were similar in age and gender but the non-congregate group had non-significantly higher ABS scores. The non-congregate group did more social, community and household activities. After matching for ABS, these outcome differences ceased to be significant. Non-congregate settings were significantly larger and had significantly more organised working methods. CONCLUSIONS The findings are consistent with other research that finds few advantages to diagnostic grouping.

Abstract
The passage of muons through matter is dominated by the Coulomb interaction with electrons and nuclei. The interaction with the electrons leads to continuous energy loss and stopping of the muons. The interaction with nuclei leads to angle "diffusion." Two muon-imaging methods that use flux attenuation and multiple Coulomb scattering of cosmic-ray muons are being studied as tools for diagnosing the damaged cores of the Fukushima reactors. Here, we compare these two methods. We conclude that the scattering method can provide detailed information about the core. Attenuation has low contrast and little sensitivity to the core.

Abstract
Recommendation 1: Multidisciplinary ApproachTo optimize treatment outcomes, the management of patients with recurrent glioblastoma should be individualized and should involve a multidisciplinary team approach, including neurosurgery, neuropathology, radiation oncology, neuro-oncology, and allied health professions.Recommendation 2: ImagingThe standard imaging modality for assessment of recurrent glioblastoma is Gd-enhanced magnetic resonance imaging (mri). Tumour recurrence should be assessed according to the criteria set out by the Response Assessment in Neuro-Oncology Working Group. The optimal timing and frequency of mri after chemoradiation and adjunctive therapy have not been established.Recommendation 3: Pseudo-progressionProgression observed by mri after chemoradiation can be pseudo-progression. Accordingly, treated patients should not be classified as having progressive disease by Gd-enhancing mri within the first 12 weeks after the end of radiotherapy unless new enhancement is observed outside the radiotherapy field or viable tumour is confirmed by pathology at the time of a required re-operation. Adjuvant temozolomide should be continued and follow-up imaging obtained.Recommendation 4: Repeat SurgerySurgery can play a role in providing symptom relief and confirming tumour recurrence, pseudo-progression, or radiation necrosis. However, before surgical intervention, it is essential to clearly define treatment goals and the expected impact on prognosis and the patient's quality of life. In the absence of level 1 evidence, the decision to re-operate should be made according to individual circumstances, in consultation with the multidisciplinary team and the patient.Recommendation 5: Re-irradiationRe-irradiation is seldom recommended, but can be considered in carefully selected cases of recurrent glioblastoma.Recommendation 6: Systemic TherapyClinical trials, when available, should be offered to all eligible patients. In the absence of a trial, systemic therapy, including temozolomide rechallenge or anti-angiogenic therapy, may be considered. Combination therapy is still experimental; optimal drug combinations and sequencing have not been established.

Abstract
BACKGROUND The prophylactic removal of asymptomatic impacted wisdom teeth is defined as the (surgical) removal of wisdom teeth in the absence of local disease. Impacted wisdom teeth may be associated with pathological changes, such as inflammation of the gums around the tooth, root resorption, gum and alveolar bone disease, damage to the adjacent teeth and the development of cysts and tumours. Other reasons to justify prophylactic removal have been to prevent late incisor crowding. When surgical removal is carried out in older patients, following the development of symptoms, the risk of postoperative complications, pain and discomfort increases. Nevertheless, in most developed countries prophylactic removal of trouble-free wisdom teeth, either impacted or fully erupted, has long been considered as 'appropriate care' and is a very common procedure. There is a need to determine whether there is evidence to support this practice. OBJECTIVES To evaluate the effects of prophylactic removal of asymptomatic impacted wisdom teeth in adolescents and adults compared with the retention (conservative management) of these wisdom teeth. SEARCH METHODS The following electronic databases were searched: the Cochrane Oral Health Group's Trials Register (to 30 March 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1), MEDLINE via OVID (1950 to 30 March 2012), and EMBASE via OVID (1980 to 30 March 2012). There were no restrictions on language or date of publication. SELECTION CRITERIA All randomised controlled trials (RCTs) on adolescents and adults comparing the effect of prophylactic removal of asymptomatic impacted wisdom teeth with no-treatment (retention). DATA COLLECTION AND ANALYSIS Six review authors screened the results of the search and assessed whether trials met the inclusion criteria for the review. Data extraction and risk of bias assessment were conducted in duplicate and independently by six review authors. Where information was unclear, authors of studies were contacted for additional information. MAIN RESULTS No RCTs were identified that compared the removal of asymptomatic wisdom teeth with retention and reported quality of life. One RCT on adolescents was identified that compared the removal of impacted mandibular wisdom teeth with retention and only examined the effect on late lower incisor crowding. This study at high risk of bias provided no evidence that extraction of wisdom teeth had an effect on lower incisor crowding over 5 years. AUTHORS' CONCLUSIONS Insufficient evidence was found to support or refute routine prophylactic removal of asymptomatic impacted wisdom teeth in adults. A single trial comparing removal versus retention found no evidence of a difference on late lower incisor crowding at 5 years, however no other relevant outcomes were measured.Watchful monitoring of asymptomatic third molar teeth may be a more prudent strategy.

Abstract
The objective of this study was to determine if volumetric modulated arc therapy (VMAT) offers advantages over intensity modulated radiotherapy (IMRT) for complex brain gliomas and evaluate the role of an additional partial arc. Twelve patients with glioma involving critical organs at risk (OAR) were selected [six low grade brainstem glioma (BG) and six glioblastoma (GB) cases]. BGs were prescribed 54 Gy/30 fractions (frx), and GB treated to 50 Gy/30 frx to a lower dose PTV (PTV50) with a simultaneous integrated boost delivering a total dose of 60 Gy/30 frx to a higher dose PTV (PTV60). VMAT was planned with a single arc (VMAT1) and with an additional coplanar partial arc spanning 90° (VMAT2). We observed VMATI improving the PTV equivalent uniform dose (EUD) for BG cases (p = 0.027), improving the V95 for the PTV50 in GB cases (p = 0.026) and resulting in more conformal GB plans (p = 0.008) as compare to IMRT. However, for the GB PTV60, IMRT achieved favorable V95 over VMAT1 and VMAT2 (0.0046 and 0.008, respectively). The GB total integral dose (ID) was significantly lower with VMAT1 and VMAT2 (p = 0.049 and p = 0.006, respectively). Both VMAT1 and VMAT2 reduced the ID, however, only at the 5 Gy threshold for BG cases (p = 0.011 and 0.005, respectively). VMAT achieved a lower spinal cord maximum dose and EUD for BG cases and higher optic nerve doses, otherwise no significant differences were observed. VMAT1 yielded the fastest treatment times and least MU. We conclude that VMAT offers faster treatment delivery for complex brain tumors while maintaining similar dosimetric qualities to IMRT. Selective dosimetric advantages in terms of spinal cord sparing and lowering the ID are observed favoring the use of an additional coplanar partial arc.

Abstract
During an 18-month period, 1606 stool specimens from laboratory-confirmed cases of Clostridium difficile infection in the North East of England were ribotyped using unrestricted polymerase chain reaction. Of these, 87.6% grew C. difficile on culture; 70% had one of 10 recognizable ribotypes of which 001, 106 and 027 were the most prevalent. The proportions of ribotypes 002 and 015 declined during the study period, whereas ribotypes 016 and 023 increased. Ribotype 005 was significantly more numerous in males and ribotype 027 was associated with significantly higher mean age. Our findings differ from national data derived from more selective testing.

Abstract
BACKGROUND Despite progress in the process of deinstitutionalisation, very little is known about the health conditions of people with intellectual disability (PWID) who live in large institutions and PWID living in small residential services, family homes or independent living within the community. Furthermore, there are no international comparison studies at European level of the health status and health risk factors of PWID living in fully staffed residential services with formal support and care compared with those living in unstaffed family homes or independent houses with no formal support. METHODS A total of 1269 persons with ID and/or their proxy respondents were recruited and face-to-face interviewed in 14 EU countries with the P15, a multinational assessment battery for collecting data on health indicators relevant to PWID. Participants were grouped according to their living arrangements, availability of formal support and stage of deinstitutionalisation. RESULTS Obesity and sedentary lifestyle along with a number of illnesses such as epilepsy, mental disorders, allergies or constipation were highly prevalent among PWID. A significantly higher presence of myocardial infarctions, chronic bronchitis, osteoporosis and gastric or duodenal ulcers was found among participants in countries considered to be at the early stage of deinstitutionalisation. Regardless of deinstitutionalisation stage, important deficits in variables related to such medical health promotion measures as vaccinations, cancer screenings and medical checks were found in family homes and independent living arrangements. Age, number of people living in the same home or number of places in residential services, presence of affective symptoms and obesity require further attention as they seem to be related to an increase in the number of illnesses suffered by PWID. DISCUSSION Particular illnesses were found to be highly prevalent in PWID. There were important differences between different living arrangements depending on the level of formal support available and the stage of deinstitutionalisation. PWID are in need of tailored primary health programs that guarantee their access to quality health and health promotion and the preventative health actions of vaccination programs, systematic health checks, specific screenings and nutritional controls. Extensive national health surveys and epidemiological studies of PWID in the EC member states are urgently needed in order to reduce increased morbidity rates among this population.

Abstract
The High-Throughput Disease-specific target Identification Program (HiTDIP) aimed to study case-control association samples for 18 common diseases. Here we present the results of a follow-up case-control association study of HiTDIP in major depressive disorder (MDD). The HiTDIP in MDD was conducted in a sample of 974 cases of recurrent MDD of white German origin collected at the Max-Planck Institute (MP-GSK) and 968 ethnically matched controls screened for lifetime absence of depression. Six genes were identified as of interest for a follow-up, based on the strength of the association and based on the interest as potential candidate target for developing new treatment for depression: Solute Carrier Family 4 Member 10 (SLC4A10), Dipeptidyl Peptidase IV (DPP4), Dopamine Receptor D3 (DRD3), Zinc Finger Protein 80 (ZNF80), Nitric Oxide Synthase 2A (NOS2A) and Peroxisome Proliferator-Activated Receptor-Gamma, Coactivator 1, Alpha (PPARGC1A). Within the current study, we attempted to follow-up these findings in a sample from the UK, the Depression Case Control (DeCC) sample consisting of 1,196 cases and 842 screened controls, phenotyped using exactly the same methods as the MP-GSK sample. Performing Cochran-Mantel-Haenzel statistics to test for genotypic and/or allelic differences between the DeCC and MP-GSK samples, we found no significant differences, thus being able to combine the two samples for association testing. In the combined sample of 2,170 MDD cases and 1,810 controls, there were positive findings in the Nitric Oxide Synthase 2A (NOS2A) gene both using single SNP analysis and haplotype analysis.

Abstract
BACKGROUND Although children with intellectual disabilities (ID) often provide accurate witness testimony, jurors tend to perceive their witness statements to be inherently unreliable. METHOD The current study explored the free recall transcripts of child witnesses with ID who had watched a video clip, relative to those of typically developing (TD) age-matched children, and assessed how mock jurors perceived these transcripts in the absence of knowledge of group (ID or TD) membership. A further aim of this research was to determine whether perceptions of credibility were associated with levels of free recall and witness characteristics (anxiety and mental age). RESULTS Mock jurors rated the testimony of children with ID as less credible than that of a TD age-matched comparison group. This was largely because of the transcripts of the children with ID containing fewer details than those of the TD children. Anxiety and mental age were found to have no effect on perceived levels of credibility. CONCLUSIONS It appears that even in the absence of knowledge of whether a child does or does not have ID, this factor still affects perceptions of credibility among mock jurors. Our findings suggest that fundamental differences in the quality of the witness transcripts lead to lower perceptions of credibility for children with ID.

Abstract
BACKGROUND Health disparities between adults with intellectual disabilities (ID) and the general population have been well documented but, to date, no dedicated assessment battery for measuring health disparity has been available. This paper reports on the development and testing of a multinational assessment battery for collecting data on a range of health indicators relevant to adults with ID. METHODS An assessment battery (the P15) was developed following piloting, and administered to samples of adults with ID, in 14 EU countries. Samples were neither random, nor representative of the countries from which they were drawn. However, within the local health administration areas selected in each country, efforts were made to ensure samples were broadly representative of the typical living circumstances, ages and ability levels of the administrative population of adults with ID. The total sample comprised 1269 adults with ID, of whom 49% were female. The mean age was 41 years (range 19 to 90). RESULTS Overall, feasibility, internal consistency and face validity of the P15 was acceptable. CONCLUSIONS With some refinement the P15 could be useful for collecting data on health indicators known to be particularly important for adults with ID. It is useable in a range of countries and has the potential to highlight health inequity for adults with ID at a national or local level. Larger scale epidemiological studies are needed to exploit the potential of the P15 to address health inequity in this group.

Abstract
BACKGROUND A higher prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization is reported in healthcare workers compared with nonhealthcare workers. HYPOTHESIS The prevalence of MRSA colonization differed in people and pets in households with healthcare workers as compared with households without healthcare workers. SUBJECTS A person and 1 dog or cat from 586 households defined as either a nonhealthcare (n = 213), veterinary healthcare (n = 211), or human healthcare (n = 162) worker household. METHODS Prospective cross-sectional study. Samples from humans and pets were cultured in vitro. Staphylococcus aureus was identified as methicillin sensitive (MSSA) or MRSA with mecA polymerase chain reaction. Pulsed-field gel electrophoresis and spa-typing were used to characterize relatedness of S. aureus and MRSA and assign USA types. RESULTS The prevalence of MSSA and MRSA in humans was 21.5% (126/586) and 5.63% (33/586), respectively, and 7.85% (46/586) and 3.41% (20/586), respectively, in pets. There were no differences in prevalences of either MSSA or MRSA between household types. The proportion of MRSA among all S. aureus isolates in humans and pets was 20.8% (33/159) and 30.3% (20/66), respectively. In < 1.0% (4/586) of households, the same strain of MRSA was found in both a person and a pet. CONCLUSIONS AND CLINICAL IMPORTANCE There were no differences in the prevalences of MSSA or MRSA between healthcare worker and nonhealthcare worker households. Pets and people colonized with S. aureus were as likely to be colonized with MRSA. Colonization of a person and their pet with the same strain of MRSA was rare.

Abstract
Major depressive disorder (MDD) is a highly prevalent disorder with substantial heritability. Heritability has been shown to be substantial and higher in the variant of MDD characterized by recurrent episodes of depression. Genetic studies have thus far failed to identify clear and consistent evidence of genetic risk factors for MDD. We conducted a genome-wide association study (GWAS) in two independent datasets. The first GWAS was performed on 1022 recurrent MDD patients and 1000 controls genotyped on the Illumina 550 platform. The second was conducted on 492 recurrent MDD patients and 1052 controls selected from a population-based collection, genotyped on the Affymetrix 5.0 platform. Neither GWAS identified any SNP that achieved GWAS significance. We obtained imputed genotypes at the Illumina loci for the individuals genotyped on the Affymetrix platform, and performed a meta-analysis of the two GWASs for this common set of approximately half a million SNPs. The meta-analysis did not yield genome-wide significant results either. The results from our study suggest that SNPs with substantial odds ratio are unlikely to exist for MDD, at least in our datasets and among the relatively common SNPs genotyped or tagged by the half-million-loci arrays. Meta-analysis of larger datasets is warranted to identify SNPs with smaller effects or with rarer allele frequencies that contribute to the risk of MDD.

Abstract
QUESTIONS Should patients with confirmed single brain metastasis undergo surgical resection? Should patients with single brain metastasis undergoing surgical resection receive adjuvant whole-brain radiation therapy (wbrt)? What is the role of stereotactic radiosurgery (srs) in the management of patients with single brain metastasis? PERSPECTIVES Approximately 15%-30% of patients with cancer will develop cerebral metastases over the course of their disease. Patients identified as having single brain metastasis generally undergo more aggressive treatment than do those with multiple metastases; however, in the province of Ontario, management of patients with single brain metastasis varies. Given that conflicting evidence has been reported, the Neuro-oncology Disease Site Group (dsg) of the Cancer Care Ontario Program in Evidence-based Care felt that a systematic review of the evidence and a practice guideline were warranted. OUTCOMES Outcomes of interest were survival, local control of disease, quality of life, and adverse effects. METHODOLOGY The medline, cancerlit, embase, and Cochrane Library databases and abstracts published in the proceedings of the annual meetings of the American Society of Clinical Oncology (1997-2005) and American Society for Therapeutic Radiology and Oncology (1998-2004) were systematically searched for relevant evidence. The review included fully published reports or abstracts of randomized controlled trials (rcts), nonrandomized prospective studies, and retrospective studies. The present systematic review and practice guideline has been reviewed and approved by the Neuro-oncology dsg, which comprises medical and radiation oncologists, surgeons, neurologists, a nurse, and a patient representative. External review by Ontario practitioners was obtained through an electronic survey. Final approval of the guideline report was obtained from the Report Approval Panel and the Neuro-oncology dsg. RESULTS QUALITY OF EVIDENCE The literature search found three rcts that compared surgical resection plus wbrt with wbrt alone. In addition, a Cochrane review, including a meta-analysis of published data from those three rcts, was obtained. One rct compared surgical resection plus wbrt with surgical resection alone. One rct compared wbrt plus srs with wbrt alone. Evidence comparing srs with surgical resection or examining srs with or without wbrt was limited to prospective case series and retrospective studies. BENEFITS Two of three rcts reported a significant survival benefit for patients who underwent surgical resection as compared with those who received wbrt alone. Pooled results of the three rcts indicated no significant difference in survival or likelihood of dying from neurologic causes; however, significant heterogeneity was detected between the trials. The rct that compared surgical resection plus wbrt with surgical resection alone reported no significant difference in overall survival or length of functional independence; however, tumour recurrence at the site of the metastasis and anywhere in the brain was less frequent in patients who received wbrt as compared with patients in the observation group. In addition, patients who received wbrt were less likely to die from neurologic causes. Results of the rct that compared wbrt plus srs with wbrt alone indicated a significant improvement in median survival in patients who received srs. No quality evidence compares the efficacy of srs with surgical resection or examines the question of whether patients who receive srs should also receive wbrt. HARMS Pooled results of the three rcts that examined surgical resection indicated no significant difference in adverse effects between groups. Postoperative complications included respiratory problems, intracerebral hemorrhage, and infection. One rct reported no significant difference in adverse effects between patients who received wbrt plus srs and those who received wbrt alone. PRACTICE GUIDELINE TARGET POPULATION The recommendations that follow apply to adults with confirmed cancer and a single brain metastasis. This practice guideline does not apply to patients with metastatic lymphoma, small-cell lung cancer, germ-cell tumour, leukemia, or sarcoma. RECOMMENDATIONS Surgical excision should be considered for patients with good performance status, minimal or no evidence of extracranial disease, and a surgically accessible single brain metastasis amenable to complete excision. Because treatment in cases of single brain metastasis is considered palliative, invasive local treatments must be individualized. Patients with lesions requiring emergency decompression because of intracranial hypertension were excluded from the rcts, but should be considered candidates for surgery. To reduce the risk of tumour recurrence for patients who have undergone resection of a single brain metastasis, postoperative wbrt should be considered. The optimal dose and fractionation schedule for wbrt is 3000 cGy in 10 fractions or 2000 cGy in 5 fractions. As an alternative to surgical resection, wbrt followed by srs boost should be considered for patients with single brain metastasis. The evidence is insufficient to recommend srs alone as a single-modality therapy. QUALIFYING STATEMENTS No high-quality data are available regarding the choice of surgery versus radiosurgery for single brain metastasis. In general, the size and location of the metastasis determine the optimal approach. The standard wbrt regimen for management of patients with single brain metastasis in the United States is 3000 cGy in 10 fractions, and this treatment is usually the standard arm in randomized studies of radiation in patients with brain metastases. Based solely on evidence, the understanding that no reason exists to choose 3000 cGy in 10 fractions over 2000 cGy in 5 fractions is correct; however, fraction size is believed to be important, and therefore 300 cGy daily (3000/10) is believed to be associated with fewer long-term neurocognitive effects than 400 cGy daily (2000/5) in the occasional long-term survivor. For that reason, many radiation oncologists in Ontario prefer 3000 cGy in 10 fractions. No data exist to either support or refute that preference; therefore, finding a resolution to this issue is not currently possible. The Neuro-oncology dsg will update the recommendations as new evidence becomes available.

Abstract
Recommendation 1 Management of patients with glioblastoma multiforme (gbm) should be highly individualized and should take a multidisciplinary approach involving neuro-oncology, neurosurgery, radiation oncology, and pathology, to optimize treatment outcomes. Patients and caregivers should be kept informed of the progress of treatment at every stage. Recommendation 2 Sufficient tissue should be obtained during surgery for cytogenetic analysis and, whenever feasible, for tumour banking. Recommendation 3 Surgery is an integral part of the treatment plan, to establish a histopathologic diagnosis and to achieve safe, maximal, and feasible tumour resection, which may improve clinical signs and symptoms. Recommendation 4 The preoperative imaging modality of choice is magnetic resonance imaging (mri) with gadolinium as the contrast agent. Other imaging modalities, such as positron emission tomography with [18F]-fluoro-deoxy-d-glucose, may also be considered in selected cases. Postoperative imaging (mri or computed tomography) is recommended within 72 hours of surgery to evaluate the extent of resection. Recommendation 5 Postoperative external-beam radiotherapy is recommended as standard therapy for patients with gbm. The recommended dose is 60 Gy in 2-Gy fractions. The recommended clinical target volume should be identified with gadolinium-enhanced T1-weighted mri, with a margin in the order of 2–3 cm. Target volumes should be determined based on a postsurgical planning mri. A shorter course of radiation may be considered for older patients with poor performance status. Recommendation 6 During rt, temozolomide 75 mg/m2 should be administered concurrently for the full duration of radio-therapy, typically 42 days. Temozolomide should be given approximately 1 hour before radiation therapy, and at the same time on the days that no radiotherapy is scheduled. Recommendation 7 Adjuvant temozolomide 150 mg/m2, in a 5/28-day schedule, is recommended for cycle 1, followed by 5 cycles if well tolerated. Additional cycles may be considered in partial responders. The dose should be increased to 200 mg/m2 at cycle 2 if well tolerated. Weekly monitoring of blood count is advised during chemoradiation therapy in patients with a low white blood cell count. Pneumocystis carinii pneumonia has been reported, and prophylaxis should be considered. Recommendation 8 For patients with stable clinical symptoms during combined radiotherapy and temozolomide, completion of 3 cycles of adjuvant therapy is generally advised before a decision is made about whether to continue treatment, because pseudo-progression is a common phenomenon during this time. The recommended duration of therapy is 6 months. A longer duration may be considered in patients who show continuous improvement on therapy. Recommendation 9 Selected patients with recurrent gbm may be candidates for repeat resection when the situation appears favourable based on an assessment of individual patient factors such as medical history, functional status, and location of the tumour. Entry into a clinical trial is recommended for patients with recurrent disease. Recommendation 10 The optimal chemotherapeutic strategy for patients who progress following concurrent chemoradiation has not been determined. Therapeutic and clinical–molecular studies with quality of life outcomes are needed.

Abstract
Question What is the safety and efficacy of interstitial chemotherapy with carmustine-loaded polymers (Gliadel wafers: MGI Pharma, Bloomington, MN, U.S.A.) in the treatment of newly diagnosed or recurrent malignant glioma (that is, glioblastoma multiforme, anaplastic astrocytoma, anaplastic oligoastrocytoma, and anaplastic oligodendroglioma)? Perspectives Malignant glioma is the most common type of primary brain tumour in adults. In general, efficacy of systemic therapy in this patient population has been disappointing, and novel treatment approaches are needed. Because several randomized controlled trials (rcts) investigating the safety and efficacy of Gliadel are available, the Neuro-oncology Disease Site Group of Cancer Care Ontario’s Program in Evidence-Based Care decided that a systematic review of the evidence was necessary. Outcomes The outcomes of interest for this review were overall survival, adverse events, and quality of life. Methodology Systematic searches of the medline, embase, and Cochrane Library databases were conducted for relevant evidence. Fully-published reports of rcts comparing treatment with Gliadel wafers to placebo or alternative treatment were selected for inclusion. Prospective cohort studies were also included. Results Two rcts that compared Gliadel to placebo in patients with newly diagnosed malignant glioma were obtained. Both rcts reported a significant survival benefit for patients who received Gliadel as compared with patients in the control group. One rct and one prospective cohort study were obtained that examined the role of Gliadel in patients with recurrent malignant glioma. The rct demonstrated a significant survival benefit for Gliadel only after adjustment for prognostic factors, and the prospective cohort study reported no survival benefit for Gliadel as compared with a historical control group. All three rcts reported similar rates of adverse events in the treatment and control groups. The most frequently reported adverse events were convulsions, confusion, brain edema, infection, hemiparesis, aphasia, and visual field defects. Conclusions Gliadel is an option for selected patients with newly diagnosed malignant glioma where a near gross total resection is possible. No evidence is available comparing Gliadel with systemic therapy, and a decision to combine Gliadel with systemic therapy should be made for patients individually. The patient population that would benefit from Gliadel (age, histology, and performance status) is unclear; further investigation is needed. Gliadel is also an option for patients with surgically resectable recurrent malignant glioma.

Abstract
There is a global need for software to manage imaging based clinical trials to speed basic research and drug development. Such a system must comply with regulatory requirements. The U.S. Food and Drug Administration (FDA) has regulations regarding software development process controls and data provenance tracking. A key unanswered problem is the identification of which data changes are significant given a workflow model for image trial management. We report on the results of our study of provenance tracking requirements and define an architecture and software development process that meets U.S. regulatory requirements using open source software components.

Abstract
We report on a case of systemic capillary leak syndrome associated with a monoclonal band on plasma electrophoresis. In our patient hospital admission was precipitated by ischaemic pain in the left lower limb, associated with polycythaemia, renal failure and hypovolaemic shock. Fluid resuscitation, venesection and renal replacement therapy were instituted but a compartment syndrome developed necessitating surgery. Failure of tracheal intubation resulted in the requirement for a surgical airway. Despite surgical and resuscitative efforts the outcome was fatal from hypovolaemia and hyperkalaemia. We aim to highlight the difficulties in managing this condition and to remind healthcare workers to include it in the differential diagnoses for patients presenting with polycythaemia; in particular polycythaemic patients with a monoclonal band on plasma electrophoresis.

Abstract
Eosinophilic esophagitis (EoE) is increasingly being diagnosed in adults presenting with dysphagia, food impactions, and chest pain. Studies to date provide conflicting data on the association of EoE and esophageal dysmotility. The objective of this study was to evaluate the prevalence of esophageal dysmotility in a cohort of patients with biopsies consistent with EoE at a military treatment facility. This is a prospective evaluation of consecutively identified patients at our institution diagnosed with EoE from March 1, 2005 to June 1, 2007. Thirty-two patients with biopsies consistent with EoE completed a symptom survey and 30 underwent esophageal manometry. The majority of EoE patients (23/30, 77%) had a normal end-expiratory lower esophageal sphincter (LES) pressure (normal range 10-35), whereas six patients had a low-normal LES pressure (6-9 mm Hg) and one patient had a decreased LES pressure (<5 mm Hg). Five patients (15.6%) were diagnosed with a nonspecific esophageal motor disorder (NSEMD). Two patients had high mean esophageal amplitude contractions >180 mm Hg (188 mm Hg, 209 mm Hg). No patient was diagnosed with nutcracker esophagus or diffuse esophageal spasm. Patients with and without NSEMD reported a similar degree of swallowing difficulty, heartburn, belching, chest pain, regurgitation, symptoms at night, and total symptom score. Likewise, eosinophil count on mucosal biopsy was similar between patients with and without a NSEMD. In this cohort, we found the prevalence of an NSEMD to be similar to that of a 10% prevalence found in a gastroesophageal reflux population.

Abstract
Migraine is frequently comorbid with depression. There appear to be common aetiological factors for both disorders, but the aetiology of migraine within depressed patients, in particular the significance of aura, has been little studied. A large sample of concordantly depressed sibling pairs [the Depression-Network (DeNT) sample] was assessed as having migraine with aura (MA), migraine without aura (MoA), probable migraine or no migraine according to International Headache Society guidelines. Correlations between siblings' migraine status were used to assess the nature of familial liability to migraine. A multiple threshold isocorrelational model fit best, in which different syndromes are conceptualized as different severities of one underlying dimension rather than as having separate aetiologies. Thus, MA and MoA were found to be different forms of the same disorder, with MA occupying the more extreme end of the spectrum of liability. Implications for our understanding of the relationship between migraine and depression are discussed.

Abstract
Increasingly, commissioners and providers of services for people with intellectual disabilities are turning to assistive technology and telecare as a potential solution to the problem of the increased demand for services, brought about by an expanding population of people with intellectual disabilities in the context of relatively static or diminishing resources. While there are numerous potential benefits of assistive technology and telecare, both for service providers and service users, there are also a number of ethical issues. The aim of this paper is to raise these issues and to set them within the ethical framework proposed by Beauchamp and Childress. There is a need for a wider debate as a first step in the development of strategies to address the issues raised in the paper.

Abstract
Bloodstream infections caused by bacteria and fungi are a major problem worldwide. These bloodstream infections can affect both people and livestock, placing a significant burden upon developed and developing economies. In this paper we describe a multiplexed testing format, which can identify a range of bacteria and fungi within a single blood sample. Key to this technique is the specificity and sensitivity of the nucleotide probes that capture the sample. The sensitivity and specificity of the probes may allow detection of disease-causing microorganisms without the need for polymerase chain reaction amplification if the dynamics of probe binding can be observed in real time.

Abstract
Experiments were conducted to compare the annealing of nano-porous aluminum oxide membranes by 2.45 GHz microwave radiation and by conventional (resistive element) furnace heating. The starting material was Al2O3 membranes that were 60 microm thick, 13 mm in diameter, and containing pores of approximately 200 nm diameter. Changes in the porosity and morphology were recorded from digital processing of scanning electron microscope (SEM) images. The data indicates that both microwave and conventionally-heated annealing resulted in a decrease of surface porosity and an apparent increase in the number of pores. However, microwave annealing consistently resulted in a 4-5% greater reduction in porosity and a greater increase in the number of (small) pores than conventionally-heated annealing. These results are consistent with a non-thermal mechanism for microwave-enhanced surface diffusion, although the complex morphology of the pores precluded a quantitative theoretical analysis.
