Abstract
BACKGROUND Bulimic eating disorders are common among female students, yet the majority do not access effective treatment. Internet-based cognitive-behavioural therapy (iCBT) may be able to bridge this gap. METHOD Seventy-six students with bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) were randomly assigned to immediate iCBT with e-mail support over 3 months or to a 3-month waiting list followed by iCBT [waiting list/delayed treatment control (WL/DTC)]. ED outcomes were assessed with the Eating Disorder Examination (EDE) at baseline, 3 months and 6 months. Other outcomes included depression, anxiety and quality of life. RESULTS Students who had immediate iCBT showed significantly greater improvements at 3 and 6 months than those receiving WL/DTC in ED and other symptoms. CONCLUSIONS iCBT with e-mail support is efficacious in students with bulimic disorders and has lasting effects.

Abstract
BACKGROUND It is common to distinguish between right and left colon cancer (RCC and LCC). But, little is known about the influence of its exact location on the tumor stage and characteristics when considering the colonic subsite within the right or left colon. METHODS During a five-year period, 29,568 consecutive patients were evaluated by data from the German multi-centered observational study "Colon/Rectal Carcinoma". Patients were split into 7 groups, each group representing a colonic subsite. They were compared regarding demographic factors, tumor stage, metastatic spread and histopathological characteristics. RESULTS Analysis of tumor differentiation and histological subtype revealed a linear correlation to the ileocecal valve, supporting the right and left side classification model. However, cancers arising from the RCC's cecum (52.3%) and LCC's splenic flexure (51.0%) showed the highest proportion of UICC stage III/IV tumors and lymphatic invasion, whereas the RCC's ascending colon (46.5%) and LCC's descending (44.7%) showed the lowest, which supports a more complex classification system, breaking down the right and left sides into colonic subsites. CONCLUSIONS Age, tumor grade and histological subtype support the right and left side classification model. However, gender, UICC stage, metastatic spread, T and N status, and lymphatic invasion correlated with a specific colonic subsite, irrespective of the side. The classification of RCC or LCC provides a general understanding of the tumor, but identification of the colonic subsite provides additional prognostic information. This study shows that the standard right and left side classification model may be insufficient.

Abstract
Repetitive Transcranial Magnetic Stimulation (rTMS) research in psychiatry mostly excludes left-handed participants. We recruited left-handed people with a bulimic disorder and found that stimulation of the left prefrontal cortex may result in different effects in left- and right-handed people. This highlights the importance of handedness and cortex lateralisation for rTMS.

Abstract
OBJECTIVES To determine whether (i) motivational enhancement therapy (MET) + cognitive behaviour therapy (CBT) compared with usual care, (ii) MET compared with usual care, (iii) or MET + CBT compared with MET was more effective in improving glycaemic control when delivered by general nurses with additional training in these techniques. DESIGN A three-arm parallel randomised controlled trial as the gold standard design to test the effectiveness of psychological treatments. SETTING The recruiting centres were diabetes clinics in seven acute trusts in south-east London and Greater Manchester. PARTICIPANTS Adults (18-65 years) with a confirmed diagnosis of type 1 diabetes for a minimum duration of 2 years and a current glycated (or glycosylated) haemoglobin (HbA1c) value between 8.2% and 15.0%. INTERVENTIONS The control arm consisted of usual diabetes care which varied between the hospitals, but constituted at least three monthly appointments to diabetes clinic. The two treatments arms consisted of usual care with MET and usual care with MET + CBT. MAIN OUTCOME MEASURES The primary outcome was HbA1c at 12 months from randomisation. Secondary outcome measures were 1-year costs measured by the Client Service Receipt Inventory at baseline, 6 months and 12 months; quality of life-years [quality-adjusted life-years (QALYs)] measured by the SF-36 (Short Form-36 Health Survey Questionnaire) and EQ-5D (European Quality of Life-5 Dimensions) at baseline and 12 months. RESULTS One thousand six hundred and fifty-nine people with type 1 diabetes were screened and 344 were randomised to MET + CBT (n = 106), MET (n = 117) and to usual care (n = 121). The 12-month follow-up rate for HbA1c was 88% (n = 305). The adjusted mean 12-month HbA1c was 0.45% lower in those treated with MET + CBT [95% confidence interval (CI) 0.16% to 0.79%, p = 0.008] than for usual care; 0.16% lower in those treated with MET (95% CI 0.20% to 0.51%, p = 0.38) than for usual care; and 0.30% lower with MET + CBT than with MET (95% CI -0.07% to 0.66%, p = 0.11). The higher the HbA1c, and the younger the participant at baseline, the greater was the reduction in HbA1c. The interventions had no effect on secondary outcomes such as depression and quality of life. The economic evaluation was inconclusive. Both interventions were associated with increased health care costs than for usual care alone. There was no significant difference in social costs. Cost effectiveness ratios, up to one year, varied considerably according to whether QALY estimates were based on EQ-5D or SF-36 and whether imputed or complete data were used in the analyses. CONCLUSIONS A combination of MET and CBT may be useful for patients with persistent sub-optimal diabetic control. MET alone appears less effective than usual care. Economic evaluation was inconclusive. TRIAL REGISTRATION Current Controlled Trials ISRCTN77044517.

Abstract
BACKGROUND Postoperative residual curarization (PORC) [train-of-four ratio (T4/T1) <0.9] is associated with increased morbidity and may delay postoperative recovery room (PACU) discharge. We tested the hypothesis that postoperative T4/T1 <0.9 increases PACU length of stay. METHODS At admission to the PACU, neuromuscular transmission was assessed by acceleromyography (stimulation current: 30 mA) in 246 consecutive patients. The potential consequences of PORC-induced increases in PACU length of stay on PACU throughput were estimated by application of a validated queuing model taking into account the rate of PACU admissions and mean length of stay in the joint system of the PACU plus patients recovering in operation theatre waiting for PACU beds. RESULTS PACU length of stay was significantly longer in patients with T4/T1 <0.9 (323 min), compared with patients with adequate recovery of neuromuscular transmission (243 min). Age (P=0.021) and diagnosis of T4/T1 <0.9 (P=0.027), but not the type of neuromuscular blocking agent, were independently associated with PACU length of stay. The incidence of T4/T1 <0.9 was higher in patients receiving vecuronium. Delayed discharge significantly increases the chances of patients having to wait to enter the PACU. The presence of PORC is estimated to be associated with significant delays in recovery room admission. CONCLUSIONS PORC is associated with a delayed PACU discharge. The magnitude of the effect is clinically significant. In our system, PORC increases the chances of patients having to wait to enter the PACU.

Abstract
The Zeiss OCT 3 optical coherance tomograph was use to map the peripillary region and the macula to analyse their correlation with each other and with glaucoma status. Both macular and nerve fibre layer thicknesses (RNFL) as measured by OCT showed statistically significant correlations with glaucoma. The strongest correlation between the diagnosis glaucoma and location of measurement was shown by the inferior macula. Macular and RNFL thickness measurements made with the Stratus OCT 3 may have utility in the clinical assessment of glaucoma.

Abstract
OBJECTIVE To validate the online questionnaire form of the Eating Disorders Examination (EDE-Q) against the interview version (EDE) in a clinic and community sample of adolescents with bulimia nervosa (BN) or atypical BN (eating disorder not otherwise specified with bulimic features - EDNOS-BN). METHOD Adolescents with BN (N=58) or EDNOS-BN (N=37) completed the EDE over the telephone and the EDE-Q online. RESULTS There were moderate to high correlations between the attitudinal scales. Eating was rated as more pathological on the EDE-Q than the EDE, except dietary restraint. As in research among adults, agreement between the two measures was low regarding binge eating episodes, but better for vomiting episodes. When compared with the EDE, the EDE-Q attitudinal scales were more valid for BN than for EDNOS-BN patients, and more valid for the clinic sample. CONCLUSION The online version of the EDE-Q has partial validity for use with adolescents. The EDE-Q might be reporting a more accurate description of current status, as it avoids possible filtering and approval aspects.

Abstract
The epidermal growth factor receptor (EGFR) is dysregulated in various tumour types such as glioblastoma multiforme (GBM), breast cancer, ovarian carcinoma, non-small cell lung cancer and other cancers. As the intracellular tyrosine kinase of the EGFR activates signalling cascades leading to cell proliferation, angiogenesis and inhibition of apoptosis, the EGFR represents an attractive target in cancer therapy. In GBM which is the most common primary central nervous system tumour in adults, the EGFR is overexpressed in about 40 to 50% of cases, and almost half of these co-express the mutant receptor subtype EGFRvIII. This EGFR variant is constitutively activated, and thereby may contribute to the aggressive and refractory course of GBM which is associated with a median survival of only 40 to 60 weeks from diagnosis. Various trials are ongoing focusing on EGFR and EGFRvIII as new therapeutic targets in GBM. Anti-EGFR monoclonal antibodies (MAbs), e.g. cetuximab, and tyrosine kinase inhibitors (TKIs), e.g. erlotinib and gefitinib, are the most advanced in clinical development. Several trials are investigating MAbs or TKIs in combination with other agents such as inhibitors of the mammalian target of rapamycin. Other still preliminary approaches targeting the EGFR are small interfering RNA, antisense RNA and ribozymes, which lead to degradation of EGFR mRNA. Further studies are needed to define their clinical potential, to identify biological predictors of response and thus to characterize subgroups of patients who will benefit from treatment with these new agents.

Abstract
AIM Data from the multicentric observation study Kolon/Rektum-Karzinome (Primärtumor) (primary colorectal carcinoma) are adduced to assess the status of surgical treatment of this condition in Germany and to compare different operative approaches in the emergency treatment of obstructive left-sided colon cancer, especially diversion (Hartmann's procedure) and primary anastomosis. PATIENTS AND METHODS Out of 15,911 patients with cancer of the left colon, recorded between 01.01.2000 and 31.12.2004, a total of 743 patients underwent emergency surgery for an obstructive tumour, performed as a radical resection. These patients were compared in respect of their risk profile and postoperative result. RESULTS In 57.9% (n=430) a one-stage operation (Group I), in 11.7% (n=87) a primary anastomosis with protective stoma (Group II), and in 30.4% (n=226), Hartmann's procedure (Group III) was performed. In Group III more patients were male, overweight and multimorbid, and more had advanced-stage tumours. The morbidity and hospital mortality (overall hospital mortality, 7.7%; n=57) did not differ significantly between the groups. The insertion of a protective stoma did not affect the rate of anastomotic insufficiency (Group I, 7%; Group II, 8.0%). CONCLUSIONS Primary anastomosis for emergency left colon carcinoma obstruction should only be regarded as indicated in cases where the risk profile is favourable. Our results suggest that in advanced obstruction and in high-risk cases Hartmann's procedure should be used. A protective stoma did not appear to confer any advantage.

Abstract
BACKGROUND Studies of patients with anorexia nervosa (AN) have shown that they do not perform well in set-shifting tasks but little is known about the neurobiological correlates of this aspect of executive function. The aim of this study was to measure serum brain-derived neurotrophic factor (BDNF) and to establish whether set-shifting difficulties are present in people with current AN and in those recovered from AN, and whether serum BDNF concentrations are correlated with set-shifting ability. METHOD Serum BDNF concentrations were measured in 29 women with current AN (AN group), 18 women who had recovered from AN (ANRec group) and 28 age-matched healthy controls (HC group). Set-shifting was measured using the Wisconsin Card Sorting Test (WCST). Eating-related psychopathology and depressive, anxiety and obsessive-compulsive symptomatology were evaluated using the Eating Disorder Examination Questionnaire (EDEQ), the Hospital Anxiety and Depression Scale (HADS), and the Maudsley Obsessive-Compulsive Inventory (MOCI) respectively. RESULTS Serum BDNF concentrations (mean+/-s.d.) were significantly lower in the AN group (11.7+/-4.9 ng/ml) compared to the HC group (15.1+/-5.5 ng/ml, p=0.04) and also compared to the ANRec group (17.6+/-4.8 ng/ml, p=0.001). The AN group made significantly more errors (total and perseverative) in the WCST relative to the HC group. There was no significant correlation between serum BDNF concentrations and performance on the WCST. CONCLUSIONS Serum BDNF may be a biological marker for eating-related psychopathology and of recovery in AN. Longitudinal studies are needed to explore possible associations between serum BDNF concentrations, illness and recovery and neuropsychological traits.

Abstract
BACKGROUND The evidence base for the treatment of adolescents with bulimia nervosa (BN) is limited. AIMS To assess the feasibility, acceptability, and clinical outcomes of a web-based cognitive-behavioural (CBT) intervention for adolescents with bulimic symptomatology. METHOD 101 participants were recruited from eating disorders clinics or from beat, a UK-wide eating disorders charity. The programme consisted of online CBT sessions ('Overcoming Bulimia Online'), peer support via message boards, and email support from a clinician. Participants' bulimic symptomatology and service utilisation were assessed by interview at baseline and at three and six months. Participants' views of the treatment package were also determined. RESULTS There were significant improvements in eating disorder symptoms and service contacts from baseline to three months, which were maintained at six months. Participants' views of the intervention were positive. CONCLUSIONS The intervention has the potential for use as a first step in the treatment of adolescents with bulimic symptomatology.

Abstract
BACKGROUND Since January 1st, 2005, the current situation for bariatric surgery has been examined by means of a voluntary quality assurance study in Germany with a multicenter design in which 38 hospitals and surgical departments participated. The data are registered in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University of Magdeburg (Germany). METHODS Data describing peri-interventional characteristics were prospectively documented in an internet online data registry. All primary bariatric procedures performed since January 1st, 2005, were registered. In addition, reoperations in patients who had previously undergone primary surgical intervention were included. As a representative excerpt from the overall prospective multicenter observational study on obesity surgery, data on the type, regimen, and time course of deep venous thrombosis (DVT) prophylaxis were documented. From the number and spectrum of complications, the incidences of clinically manifest DVT or pulmonary embolism (PE) were derived during the in-hospital course and follow-up in conjunction with the type of surgical procedure and body mass index (BMI). RESULTS Overall, 3,122 bariatric procedures were performed at 38 German hospitals between January 2005 and December 2007. These procedures were subdivided into 2,869 primary operations and 253 revisions (sex ratio, male to female = 25.6:74.4%). The average BMI of all patients was 48.5 kg/m(2) in 2005, 48.4 kg/m(2) in 2006, and 48.0 kg/m(2) in 2007. In 2005 and 2006, gastric banding (GB) was the most commonly performed operation, followed by Roux-en-Y gastric bypass (RYGBP). In 2007, RYGBP was carried out in 42.1% of all bariatric procedures. Interestingly, the incidence of deep venous thrombosis (DVT) was only 0.06%, whereas PE occurred in 0.06% of patients only after hospital discharge. The DVT prophylaxis protocol used has been changed for the last 2 years: the majority of patients with a BMI above 50 kg/m(2) received low-molecular-weight heparin twice a day. CONCLUSION In Germany, a trend from GB to sleeve gastrectomy (SG) and malabsorptive approach has been evaluated. This trend is associated with differences of the DVT prophylaxis regimen in the profile of bariatric surgical patients depending on BMI and the type of bariatric procedure. Despite the low incidence of DVT and pulmonary embolism (PE) detected, there is a lack of evidence on a reasonable regimen for sufficient DVT prophylaxis in bariatric surgery; instead, there are only recommendations from the guidelines and statements of a specific medical society. Therefore, prospective studies are necessary to determine the optimal DVT prophylaxis for bariatric surgical patients as well as obese patients undergoing surgery.

Abstract
The geometric phase has been proposed as a candidate for noise resilient coherent manipulation of fragile quantum systems. Since it is determined only by the path of the quantum state, the presence of noise fluctuations affects the geometric phase in a different way than the dynamical phase. We have experimentally tested the robustness of Berry's geometric phase for spin-1/2 particles in a cyclically varying magnetic field. Using trapped polarized ultracold neutrons, it is demonstrated that the geometric phase contributions to dephasing due to adiabatic field fluctuations vanish for long evolution times.

Abstract
BACKGROUND Healthy adolescents, and adults who engage in reward-driven, risky behaviours, demonstrate poor decision-making ability. Decision making in deliberate self-harm (DSH), a reward-driven, high-risk behaviour, has received little attention. This study assessed decision making and problem solving in adolescents with current or past SH. METHOD Decision making and problem solving were assessed using the Iowa Gambling Task (IGT) and the Means-Ends Problem-Solving Procedure (MEPS) respectively in 133 adolescents (57 healthy and 22 depressed controls with no SH history and 54 with SH history). A second analysis separated the SH group into current (n=30) and past (n=24) SH. RESULTS The collective performance of adolescents with SH history did not differ from depressed or healthy adolescents on the IGT. However, current self-harming adolescents had a trend towards more high-risk choices (p=0.06) than those with previous SH history and were the only group not to significantly improve over time, persisting with high-risk strategy throughout. Those who no longer self-harmed learnt to use a low-risk strategy similar to healthy and depressed controls. Recency of last SH episode correlated with IGT performance. Depressed participants performed well on the IGT but poorly on the MEPS. By contrast, both collective and divided SH groups had comparable MEPS scores to healthy controls, all performing better than depressed participants. CONCLUSION Poor decision making is present in adolescents who currently self-harm but not in those with previous history; improvement in decision-making skills may therefore be linked to cessation of self-harm. Depressed adolescents who do and do not self-harm may have distinct characteristics.

Abstract
BACKGROUND Cognitive-behavioural self-care is advocated as a first step in the treatment of bulimia nervosa. AIMS To examine the effectiveness of a CD-ROM-based cognitive-behavioural intervention in bulimia nervosa and eating disorder not otherwise specified (NOS) (bulimic type) in a routine setting. METHOD Ninety-seven people with bulimia nervosa or eating disorder NOS were randomised to either CD-ROM without support for 3 months followed by a flexible number of therapist sessions or to a 3-month waiting list followed by 15 sessions of therapist cognitive-behavioural therapy (CBT) (ISRCTN51564819). Clinical symptoms were assessed at pre-treatment, 3 months and 7 months. RESULTS Only two-thirds of participants started treatment. Although there were significant group x time interactions for bingeing and vomiting, favouring the CD-ROM group at 3 months and the waiting-list group at 7 months, post hoc group comparisons at 3 and 7 months found no significant differences for bingeing or vomiting. CD-ROM-based delivery of this intervention, without support from a clinician, may not be the best way of exploiting its benefits.

Abstract
BACKGROUND Most studies on bariatric surgery outcomes are performed as clinical trials or reflect the clinical experience in single centers. The status of bariatric surgery in Germany has been examined since January 1st, 2005 with the cooperation of clinics and hospitals at the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University of Magdeburg (Germany). METHODS In this prospective multicenter observational study, the data obtained for all primary bariatric procedures, including all repeated operations, performed on consecutive patients with morbid obesity at participating hospitals from 2005 to 2007 were prospectively collected using an Internet online data registry. In particular, perioperative characteristics, such as the spectrum of diagnostic measurements, type of surgical procedures, and short- and long-term outcomes, were investigated. RESULTS During the study period, 629 surgical procedures were performed at 21 hospitals in 2005, 828 procedures at 32 hospitals in 2006, and 1,666 procedures at 35 hospitals in 2007. In 2005 and 2006, gastric banding was the most frequently performed operation, followed by the Roux-en-Y gastric bypass (RYGBP). In 2007, a RYGBP was carried out in 42.1% of all bariatric procedures. Among all patients, 74.4% were female. The mean body mass index (BMI) was 48.5 kg/m(2) in 2005, 48.4 kg/m(2) in 2006, and 48.0 kg/m(2) in 2007. Follow-up data after 12 months were available for 63.8% of the patients in 2005 and 2006; these data showed greater reduction of BMI after malabsorptive rather than restrictive bariatric procedures. The mortality was 0.1% (30 days) and 0.16% (overall). CONCLUSION As indicated by the worldwide trend, there is an ongoing change from restrictive bariatric procedures to malabsorptive procedures and sleeve gastrectomy. Although the BMIs of German patients undergoing bariatric surgery appear to be substantially higher than those of patients from most other countries, there were no differences in intraoperative and short-term complications or in overall outcomes during follow-up when compared with published studies.

Abstract
BACKGROUND Since January 1st 2005, the situation of bariatric surgery in Germany has been examined. The data are registered in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke-University Magdeburg. METHODS The data registration took place prospectively in an internet online data base. All primary bariatric procedures performed since January 1st 2005 were detected as well as re-operations in patients who had been operated before. RESULTS 629 patients underwent bariatric surgery in 21 hospitals in 2005 and 828 patients were operated in 32 hospitals in 2006. The mostly performed operation was gastric banding with 46.8 %, followed by Roux-Y gastric bypass with 38.5 %. 74.4 % of the patients were female. The medium BMI of all patients was 48.5 kg/m2 in 2005 and 48.4 kg/m2 in 2006. Follow-up data were available for 71.2 % of the patients operated in 2005. These data show a higher reduction of BMI after malabsorptive than after restrictive bariatric procedures. CONCLUSION A trend from restrictive bariatric procedures to a malabsorptive approach could be observed. In Germany the BMI of patients undergoing bariatric surgery is higher than in most countries world-wide. No differences could be detected in intraoperative and short-term complications as well in the complication rate in the first year of follow-up in comparison with the literature.

Abstract
BACKGROUND Adjustable silicone gastric banding (ASGB) is an effective treatment in morbid obesity. Band migration is a long-term complication. Causes, clinical symptoms, timing and incidence are investigated in single centres only. In Germany, since January 1st, 2005, practice in bariatric surgery has been investigated in German prospective multicenter trial for quality assurance in obesity surgery. MATERIALS AND METHODS All patients underwent ASGB in two centres of bariatric surgery in Germany were prospectively registered using a computer-based data form. Patients with band migration were retrospectively evaluated, in particular, causes and characteristics of its management. The results were correlated with data obtained from the German prospective multicentre trial. RESULTS In total, 493 patients were enrolled in the study from February 1995 to February 2007. The follow-up rate was 79.9% (mean follow-up time period, 78.7 months; range, 2-148 months). Fifteen patients (3.0%) developed migration. In 14 cases, migration occurred within the range of 30-86 months after implantation. In one case, migration occurred 10 months after repositioning of the band. In the German multicentre trial, 629 patients underwent surgery during 2005 and 827 patients in 2006. In both periods, 74.4% of the patients were female and 25.6% male. The most frequently performed operation was ASGB (46.8%) followed by Roux-en-Y gastric bypass (38.5%). CONCLUSION Band migration requires band removal. Different symptoms and complications influence the kind of band removal. Multicentre data were evident in the case of high long-term complication rate after ASGB. Data of the German multicentre trial show the trend from restrictive bariatric procedures to malabsorptive approach.

Abstract
The segregation of mitochondrial genomes and the inheritance of mitochondrial DNA are constant matters of debate. To obtain more information about this issue and to answer the question whether or not it is possible to distinguish mitochondrial DNA (mtDNA) samples from monozygous individuals by analysing heteroplasmic length variants, 290 monozygous and 121 dizygous twin pairs and 34 sets of multiples were studied by RFLP and partly by direct sequencing. A factor D describing the respective pattern of length variants in a given sample was also calculated. The results show that monozygous individuals exhibit a significantly lower median and closer distribution of D than non-monozygous siblings. Thus, a differentiation of mtDNA samples from monozygous twins by this trait is not possible. The high percentage of heteroplasmic individuals, the low median of the D values and the unexpectedly very similar distribution of length variants in monozygotic individuals support the existence of a relatively wide bottleneck or the assumption of a regeneration of length heteroplasmy following a tight bottleneck and agree with a random segregation of mtDNA genomes in dividing oocytes.

Abstract
Usnea barbata and its major constituent usnic acid are potent antimicrobial agents. Here, we have investigated anti-inflammatory properties of an U. barbata extract (UBE) containing 4% usnic acid in an ultraviolet-B (UVB) model with HaCaT keratinocytes. UVB irradiation induced PGE(2) production and COX-2 expression in a time and dose-dependent manner. UBE inhibited PGE(2) production at a half-maximal concentration of 60 microg/ml (2.4 microg/ml usnic acid) that did not affect the UVB-induced upregulation of COX-2, suggesting an effect on enzyme activity rather than on protein expression. The inhibition of PGE(2) production by UBE was not due to cytotoxicity. Besides its known antimicrobial properties, UBE displays specific UVB protective effects that might be useful in the topical treatment of UVB-mediated inflammatory skin conditions.

Abstract
UNLABELLED REASON FOR THE STUDY: Little is known about how motivation to change evolves over the course of an eating disorder. The present study compared 'stage of change' and motivation, confidence and readiness to change in two groups of patients with bulimia nervosa (BN), adolescents with a short duration of illness and adults with a long duration of illness. METHOD Patients completed the Severity of eating disorder symptomatology scale, Hospital Anxiety and Depression Scale and measures of stage of change and motivation, readiness and confidence to change their bulimic symptomatology at pre-treatment. MAIN FINDINGS Short- and long duration groups did not differ in illness severity, comorbidity, stage of change, motivation, readiness, and confidence to change. There were, however, some differences between groups in terms of the relationship between motivational measures, illness severity, duration and comorbidity. CONCLUSIONS There seem to be more similarities than differences between adolescents with short duration of illness and those with well-established BN in terms of their motivation to change.

Abstract
Physiotherapy is a well established part of the rehabilitation of peripheral nerve paralysis. The aim of this type of treatment is to re-establish arbitrary functions by improving the patients' active and passive mobility as well as their strength and stamina. IMF-Therapy (Intention controlled Myo-Feedback) is an innovative method in the treatment of peripheral nerve lesions that goes beyond the purely neuro-scientific framework and also takes into account methods and concepts of the psychology of learning. The essential assumption is that things learnt in the past are firmly established in the long term motor memory and can be reactivated by the patient. From results achieved in 32 patients treated with this therapy it can be concluded that IMF-Therapy may be a promising additional rehabilitation tool in peripheral nerve lesion.

Abstract
BACKGROUND Anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS) are common and disabling disorders. Many patients experience difficulties accessing specialist psychological treatments. Pure self-help (PSH: self-help material only) or guided self-help (GSH: self-help material with therapist guidance), may bridge this gap. MAIN OBJECTIVE Evaluate evidence from randomised controlled trials (RCTs) / controlled clinical trials (CCTs) for the efficacy of PSH/GSH with respect to eating disorder symptoms, compared with waiting list or placebo/attention control, other psychological or pharmacological treatments (or combinations/augmentations) in people with eating disorders. SECONDARY OBJECTIVE Evaluate evidence for the efficacy of PSH/GSH regarding comorbid symptomatology and costs. SEARCH STRATEGY CCDANCTR-Studies and CCDANCTR-References were searched in November 2005, other electronic databases were searched, relevant journals and grey literature were checked, and personal approaches were made to authors. SELECTION CRITERIA Published/unpublished RCTs/CCTs evaluating PSH/GSH for any eating disorder. DATA COLLECTION AND ANALYSIS Data was extracted using a customized spreadsheet. Relative Risks (RR) were calculated from dichotomous data and weighted/standardized mean differences (WMD/SMD) from continuous data, using a random effects model. MAIN RESULTS Twelve RCTs and three CCTs were identified, all focusing on BN, BED, EDNOS or combinations of these, in adults, using manual-based PSH/GSH across various settings. Primary comparisons:At end of treatment, PSH/GSH did not significantly differ from waiting list in abstinence from bingeing (RR 0.72, 95% CI 0.47 to 1.09), or purging (RR 0.86, 95% CI 0.68 to 1.08), although these treatments produced greater improvement on other eating disorder symptoms, psychiatric symptomatology and interpersonal functioning but not depression. Compared to other formal psychological therapies, PSH/GSH did not differ significantly at end of treatment or follow-up in improvement on bingeing and purging (RR 0.99, 95% CI 0.75 to 1.31), other eating disorder symptoms, level of interpersonal functioning or depression. There were no significant differences in treatment dropout. Secondary comparisons:One small study in BED found that cognitive-behavioural GSH compared to a non-specific control treatment produced significantly greater improvements in abstinence from bingeing and other eating disorder symptoms. Studies comparing PSH with GSH found no significant differences between treatment groups at end of treatment or follow-up. Comparison between different types of PSH/GSH found significant differences on eating disorder symptoms but not on bingeing/purging abstinence rates. AUTHORS' CONCLUSIONS PSH/GSH may have some utility as a first step in treatment and may have potential as an alternative to formal therapist-delivered psychological therapy. Future research should focus on producing large well-conducted studies of self-help treatments in eating disorders including health economic evaluations, different types and modes of delivering self-help (e.g. computerised versus manual-based) and different populations and settings.

Abstract
We used a torsion pendulum containing approximately 9 x 10(22) polarized electrons to search for CP-violating interactions between the pendulum's electrons and unpolarized matter in the laboratory's surroundings or the Sun, and to test for preferred-frame effects that would precess the electrons about a direction fixed in inertial space. We find, /g(P)(e)g(S)(N)//(Planck's constant x c) < 1.7 x 10(-36), and /g(A)(e)g(V)(N)//(Planck's constant x c) < 4.8 x 10(-56) for lambda > 1 AU. Our preferred-frame constraints, interpreted in the Kostelecký framework, set an upper limit on the parameter /b(e)/ <or= 5.0 x 10(-21) eV that should be compared to the benchmark value m(e)(2)/M(Planck)= 2 x 10(-17) eV.

Abstract
BACKGROUND Refugee doctors constitute a potentially valuable resource for reducing the recruitment crisis in psychiatry. However, various hurdles make their route into the National Health Service (NHS) difficult. AIMS To explore the perceptions and experiences of refugee doctors trying to practise psychiatry in the UK. METHOD Thirty-one refugee doctors participated in qualitative interviews designed to elicit their experiences in trying to practise as doctors in the UK. Twenty were re-interviewed about 6 months later. RESULTS Doctors identified a range of practical problems that made it difficult for them to take the required steps towards practising in the UK. These included lack of appropriate information, lack of a clear route through the system and feelings of isolation. The English language examination was seen as a particular bottleneck, as were finding clinical attachments. The psychological impact of the experience was profound. CONCLUSIONS These findings have important implications for how refugee doctors are introduced to the practice of psychiatry in the NHS.
