Abstract
AIM: To evaluate esophageal mucosal defense mechanisms at an epithelial level to establish if pantoprazole treatment can induce ultrastructural healing and improvement in the proliferation activity of the esophageal epithelium in gastroesophageal reflux disease (GERD).
METHODS: This was a single-blinded study for pH-monitoring, and histological, ultrastructural and MIB1 immunostaining evaluation. Fifty eight patients with GERD were enrolled and underwent 24 h pH-monitoring and endoscopy. Patients were treated for 12 and 24 mo with pantoprazole. Esophageal specimens were taken for histological and ultrastructural evaluation, before and after the treatment.
RESULTS: With transmission electron microscopy, all patients with GERD showed ultrastructural signs of damage with dilation of intercellular spaces (DIS). After 3 mo of therapy the mean DIS values showed a significant reduction and the mean MIB1-LI values of GERD showed an increase in cell proliferation. A further 3 mo of therapy significantly increased cell proliferation only in the erosive esophagitis (ERD) group.
CONCLUSION: Three months of pantoprazole therapy induced ultrastructural healing of mucosal damage in 89% and 93% of ERD and non-erosion patients, respectively. Moreover, long-term pantoprazole treatment may be helpful in increasing the capability for esophageal cell proliferation in GERD, particularly in ERD patients.

Abstract
OBJECTIVES Study aims were to evaluate effects of Bacopa monnieri whole plant standardized dry extract on cognitive function and affect and its safety and tolerability in healthy elderly study participants. DESIGN The study was a randomized, double-blind, placebo-controlled clinical trial with a placebo run-in of 6 weeks and a treatment period of 12 weeks. SETTING/LOCATION Volunteers were recruited from the community to a clinic in Portland, Oregon by public notification. SUBJECTS Fifty-four (54) participants, 65 or older (mean 73.5 years), without clinical signs of dementia, were recruited and randomized to Bacopa or placebo. Forty-eight (48) completed the study with 24 in each group. INTERVENTIONS Standardized B. monnieri extract 300 mg/day or a similar placebo tablet orally for 12 weeks. OUTCOME MEASURES The primary outcome variable was the delayed recall score from the Rey Auditory Verbal Learning Test (AVLT). Other cognitive measures were the Stroop Task assessing the ability to ignore irrelevant information, the Divided Attention Task (DAT), and the Wechsler Adult Intelligence Scale (WAIS) letter-digit test of immediate working memory. Affective measures were the State-Trait Anxiety Inventory, Center for Epidemiologic Studies Depression scale (CESD)-10 depression scale, and the Profile of Mood States. Vital signs were also monitored. RESULTS Controlling for baseline cognitive deficit using the Blessed Orientation-Memory-Concentration test, Bacopa participants had enhanced AVLT delayed word recall memory scores relative to placebo. Stroop results were similarly significant, with the Bacopa group improving and the placebo group unchanged. CESD-10 depression scores, combined state plus trait anxiety scores, and heart rate decreased over time for the Bacopa group but increased for the placebo group. No effects were found on the DAT, WAIS digit task, mood, or blood pressure. The dose was well tolerated with few adverse events (Bacopa n = 9, placebo n = 10), primarily stomach upset. CONCLUSIONS This study provides further evidence that B. monnieri has potential for safely enhancing cognitive performance in the aging.

Abstract
BACKGROUND AND AIMS The metabolic profile and morphologic aspects of normal and pathologic human gastric mucosa were studied. The aim of the present research was the application of ex vivo high-resolution magic angle spinning magnetic resonance spectroscopy (HR-MAS MRS) to the human gastric tissue to get information on the molecular steps involved in gastric carcinogenesis and the identification of biochemical markers useful for the development of in vivo MRS methodologies to diagnose gastric pathologies in clinical situations. METHODS Twelve normal subjects, five with autoimmune atrophic gastritis, five with Helicobacter pylori infection, and five with adenocarcinoma were examined. Ten biopsies were taken during endoscopy from each patient. Specimens from carcinoma were also obtained during gastrectomy. Of the 10 biopsies, 4 were used for histologic evaluation, 4 were fixed in glutaraldehyde and processed for transmission and scanning electron microscopy, and 2 were immersed in liquid nitrogen and stored at -85 degrees C for monodimensional and bidimensional ex vivo HR-MAS MRS analysis. RESULTS Ex vivo HR-MAS MRS identified glycine, alanine, free choline, and triglycerides as possible molecular markers related to the human gastric mucosa differentiation toward preneoplastic and neoplastic conditions. Ultrastructural studies of autoimmune atrophic gastritis and gastric adenocarcinoma revealed lipid accumulations intracellularly and extracellularly associated with a severe prenecrotic hypoxia and mitochondria degeneration. CONCLUSIONS This is the first report of synergic applications of ex vivo HR-MAS MRS and electron microscopy in studying the human gastric mucosa differentiation. This research provides useful information about some molecular steps involved in gastric carcinogenesis. The biochemical data obtained on gastric pathologic tissue could represent the basis for clinical applications of in vivo MRS.

Abstract
OBJECTIVES To assess the feasibility and acceptability of studying whole systems of Traditional Chinese Medicine (TCM) and Naturopathic medicine (NM) in the treatment of temporomandibular disorders (TMD), and to determine whether there is indication to support further research. DESIGN A pilot study using a randomized controlled clinical trial design of whole system TCM and NM versus state-of-the-art specialty care (SC). SETTING/LOCATION Kaiser Permanente Northwest (KPNW), and practitioner offices in Portland, Oregon. SUBJECTS One hundred and sixty (160) women 25-55 years of age attending a KPNW TMD specialty clinic. INTERVENTIONS Whole system TCM and NM, and KPNW TMD clinic SC; the intervention protocols were designed to model the individually tailored type of community care offered in alternative medicine practices in Portland and in the KPNW TMD clinic, using protocols that enhanced similarities among practitioners within each system and permitted full descriptions of the treatments provided. OUTCOME MEASURES TMD was ascertained using the Research Diagnostic Criteria/TMD; outcomes were self-reported worst and average facial pain and interference with activities (scaled 0-10 where 10 is worst). RESULTS Of 948 consecutive eligible patients, 160 were randomized to one of three arms; 128 provided endpoint data. TCM and NM demonstrated significantly greater in-treatment reductions for worst facial pain compared to SC (adjusted regression analysis; higher negative values indicate greater improvement, = -1.11 +/- 0.43, p = 0.010 and -1.02 +/- 0.45, p = 0.025 for TCM and NM, respectively, compared to SC) and at 3 months post-treatment (-1.07 +/- 0.51, p = 0.037 and -1.27 +/- 0.54, p = 0.019 for TCM and NM versus SC, respectively). Additionally, TCM provided significantly greater decreases in average pain than SC; NM provided significantly greater decreases than SC or TCM in TMD-related psychosocial interference. CONCLUSIONS These alternative medicine approaches each resulted in significantly greater reduction of pain and psychosocial interference than SC. Further research on the potential benefits of traditional whole systems of medicine for TMD appears warranted.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) use is high in people with multiple sclerosis (MS), yet there are limited reports on safety and effectiveness of CAM in MS. Naturopathic medicine encompasses a broad range of CAM modalities and may improve quality of life in patients with MS. OBJECTIVE To assess quality of life in MS subjects who received interventions designed to "model" the "whole practice" of naturopathy. DESIGN A pilot, randomized, controlled study with a 6-month intervention period. PARTICIPANTS Participants who met criteria for clinically definite MS. INTERVENTIONS The 3 intervention arms were usual care, naturopathic medicine plus usual care, and MS education plus usual care. OUTCOME MEASURES The primary outcome measure was quality of life (36-item short form health survey [SF-36]). Secondary outcome measures included fatigue (Modified Fatigue Impact Scale); depression (Beck Depression Inventory); cognition battery (Stroop test and Paced Auditory Serial Addition Test 3), and neurologic impairment (Expanded Disability Status Scale [EDSS] and Multiple Sclerosis Functional Composite). Adverse event reporting and laboratory measures were used to assess safety. RESULTS Forty-five (45) participants (15 per group) were randomized and all completed the 6-month intervention. There were no significant differences between groups on any outcome measure. There was a trend in favoring the naturopathic group in the General Health subscale of the SF-36 (p = 0.11), Timed Walk (p = 0.11), and neurologic impairment (EDSS) (p = 0.07). There was a trend favoring the Education group in the Stroop attention test (p = 0.07). There was no difference between groups in adverse events or laboratory changes. CONCLUSIONS Naturopathic medicine combined with usual care for MS showed a trend in improvement in the General Health subscale of the SF-36, Timed Walk, and neurologic impairment. Evaluation of naturopathic medicine, as a multimodality regimen, warrants further investigation.

Abstract
BACKGROUND Comparative studies of proton pump inhibitors (PPIs) have revealed that acid reflux is influenced by PPI treatment, formulations and dosing regimens. Wireless pH capsules have circumvented some of the limitations of conventional catheter-based pH testing with the additional advantage of 96-h recording periods. AIM To clarify the effectiveness of intra-oesophageal acid suppression by omeprazole, pantoprazole and lansoprazole in non-erosive reflux disease patients through a 4-day monitoring of oesophageal pH and related symptoms. METHODS Twenty-four patients with typical symptoms of gastro-oesophageal reflux disease were enrolled and administered upper endoscopy and placement of a wireless pH capsule. Patients randomly received omeprazole, pantoprazole or lansoprazole for 3 days after the first 24 h. Symptom-reflux associations were expressed using the symptom index (SI). RESULTS All patients completed the study. Significant decrease in acid exposure occurred on day 2 and in each successive day in all groups. Pantoprazole and omeprazole are more effective than lansoprazole at inducing a normalization of intra-oesophageal acid exposure at days 2 and 3. Significant reduction in SI at day 2 was observed. CONCLUSIONS Four-day ambulatory oesophageal pH monitoring is feasible and safe. Omeprazole, pantoprazole and lansoprazole have an equivalent potency for normalizing intra-oesophageal acid exposure after 3 days of treatment in non-erosive reflux disease patients.

Abstract
BACKGROUND Chronic refractory pouchitis is a long-term complication after ileal pouch-anal anastomosis and it may be associated with ileal inflammation. AIM To determine the efficacy of infliximab in treatment of chronic refractory pouchitis complicated by ileitis, using a wireless capsule endoscopy. METHODS Sixteen patients with chronic refractory pouchitis complicated by ileitis were enrolled. Pouchitis was diagnosed by clinical, endoscopic and histological criteria. Ileitis was documented using wireless capsule endoscopy. Duodenum-jejunum and proximal-middle ileum were evaluated and the presence of small lesions and large lesions were noted. Crohn's disease, intestinal infections were excluded in all patients. Patients were treated with infliximab and clinical response was recorded. Wireless capsule endoscopy was repeated at week 10 and Pouchitis Disease Activity Index score was determined. RESULTS Ten patients were enrolled and completed the study. Clinical remission was achieved in nine patients. At wireless capsule endoscopy and pouch endoscopy, a complete recovery of lesions was observed in eight patients. One patient presented four small lesions of the ileum at the 6 weeks of treatment and one patient did not show any modification. Clinical and endoscopic remission was maintained in these eight patients at least 6 months. CONCLUSION These preliminary results indicate that infliximab may be recommended for the treatment of chronic refractory pouchitis complicated by ileitis.

Abstract
PURPOSE Pouchitis is the major long-term complication after ileal-pouch anal anastomosis for ulcerative colitis. Broad-spectrum antibiotics are the mainstay of treatment in this condition. Recently, we have shown the efficacy of a highly concentrated probiotic preparation (VSL#3, 900 billions/sachet lyophilized viable bacteria) in preventing relapses of chronic pouchitis and in preventing pouchitis onset. This study was designed to evaluate the efficacy of high-dose VSL#3 in the treatment of mildly active pouchitis. METHODS Twenty-three consecutive patients with mild pouchitis, defined as a score of between 7 and 12 in the Pouchitis Disease Activity Index, which includes clinical, endoscopic, and histological criteria, were treated with VSL#3, 2 sachets b.i.d. (3,600 billion bacteria/day) for four weeks. Symptomatic, endoscopic, and histologic evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of a Pouchitis Disease Activity Index clinical score of <or=2, endoscopic score of <or=1, and total Pouchitis Disease Activity Index score of <or=4. Patients in remission after treatment were treated with VSL#3, 1 sachet b.i.d. (1,800 billion bacteria), as maintenance treatment for six months. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS Sixteen of 23 patients (69 percent) were in remission after treatment. The median total Pouchitis Disease Activity Index scores before and after therapy were 10 (range, 9-12) and 4 (range, 2-11), respectively (P < 0.01). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 110 (range, 90-140) to 200 (range, 95-220; P < 0.001). All 16 patients who went into remission maintained remission during maintenance treatment. Only one patient experienced a transient bloating at the beginning of treatment. CONCLUSIONS High doses of the probiotic VSL#3 are effective in the treatment of mild pouchitis. Further controlled studies are warranted.

Abstract
OBJECTIVE To investigate associations between survival and use of psychological and spiritual activities practiced over 1 year in HIV-positive (HIV+) patients. METHOD Nine hundred one HIV+ adults living in the United States using at least 1 form of complementary and alternative medicine (CAM) completed a questionnaire 3 times between 1995 and 1998. Information on specific mind-body therapies included psychotherapy (group therapy, support groups, individual therapy) and spiritual therapies (self-defined "spiritual" activities, prayer, meditation, affirmations, psychic healing, visualizations). Subsequent death was ascertained from the National Death Index (NDI). Cox proportional-hazards regression assessed risk of death through 1999. RESULTS Use of any psychological therapy reported in both the 6-month and 12-month follow-up questionnaires (1 year continuous use) was associated with a reduced risk of death (hazard ratio [HR]: 0.5, 95% CI: 0.3-0.9) adjusted for income, clinical acquired immune deficiency syndrome, CD4 count, smoking, alcohol use, and use of antiretroviral therapy or highly active antiretroviral therapy (HAART). The relationship between spiritual activities and survival was modified by use of HAART, which may reflect severity of illness. Individuals not currently using HAART and who participated in spiritual activities over the previous year were found to be at a reduced risk of death (HR: 0.4, 95% CI: 0.2-0.9) compared to those not practicing spirituality. CONCLUSIONS Participation in spiritual and psychological therapies may be related to beneficial clinical outcomes in HIV+ individuals, including improved survival. Due to the self-selection of therapies in this observational cohort, it is not possible to distinguish use of the therapies from other characteristics or activities of the people participating in them.

Abstract
BACKGROUND Erosive esophagitis is a frequent endoscopic feature in patients with gastro-oesophageal reflux disease. However, most of patients with heartburn/regurgitation have a non-erosive reflux disease. The reason for this heterogeneous impact of gastro-oesophageal reflux disease on oesophageal mucosa is unknown to date. AIM To evaluate the cell proliferation status of oesophageal epithelium in both healthy normal subjects and patients with gastro-oesophageal reflux disease with or without erosions. MATERIALS AND METHODS All the subjects underwent endoscopy and biopsies were taken at 5 cm from the squamo-columnar junction. Specimens were analysed both at histology and at transmission electron microscopy. Cell proliferation was evaluated by MIB1 immunostaining. Of the 85 subjects were studied, 10 were healthy controls with normal pH-testing and macroscopical, histological and ultrastructural patterns; 37 were patients with erosive esophagitis, and 38 patients with non-erosive reflux disease. RESULTS At histology, of the 37 patients affected by erosive esophagitis, 30 had normal mucosa and 7 showed mild oesophagitis. One patient with non-erosive reflux disease showed signs of oesophagitis at histology. At TEM, all patients with gastro-oesophageal reflux disease had ultrastructural patterns of damage i.e. dilations of intercellular spaces (DIS), and all controls had a normal ultrastructural pattern. The mean (+/-SD) MIB1-LI values of normal subjects and non-erosive reflux disease and erosive oesophagitis patients were 62.2% (+/-9.1), 29.7% (+/-7.2) and 16.2% (+/-5.2), respectively; there were significant differences among the three groups (p<0.001). CONCLUSIONS Oesophageal mucosa of patients with reflux symptoms presents a decrease in MIB1 immunostaining of 50% and 25% in non-erosive reflux disease and erosive esophagitis patients with respect to normal subjects.

Abstract
BACKGROUND Collagenous colitis (CC) and lymphocytic colitis (LC) are chronic inflammatory diseases of the colon with a benign and sometimes relapsing course. Frequency among patients with chronic diarrhea and normal looking colonoscopy is around 10-15%. To date, treatment of CC and LC is not well defined. Data about these conditions are mostly derived from retrospective studies. The aim of the present study was to evaluate the response to treatment and the clinical course of CC and LC in a large group of patients prospectively diagnosed. METHODS AND RESULTS A total of 819 patients underwent a colonoscopy because of chronic watery diarrhea and among them we found 41 patients with LC and 23 with CC. These patients were later randomized and assigned to treatment with mesalazine or mesalazine + cholestyramine for 6 months. Fifty-four patients (84.37%) had resolved diarrhea in less than 2 weeks. After 6 months a colonoscopy with biopsies was repeated. Clinical and histological remission was achieved in 85.36% of patients with LC and in 91.3% with CC, with a better result in patients with CC treated with mesalazine + cholestyramine. During a mean period of 44.9 months, 13% of patients relapsed; four with LC and three with CC. They were retreated for another 6 months. At the end of this period one patient with CC was still symptomatic and persistence of CC was confirmed at histology. CONCLUSIONS Treatment with mesalazine seems to be an effective therapeutic option for LC to date, while mesalazine + cholestyramine seems to be more useful in the treatment of CC.

Abstract
BACKGROUND Pouchitis is a common long-term complication after ileal pouch anal anastomosis for ulcerative colitis. Chronic refractory pouchitis is a treatment-resistant condition that affects 5-15% of patients. AIM To test the hypothesis of a small bowel involvement using wireless capsule endoscopy. MATERIAL AND METHODS This is a single-blind, prospective, cohort study. Twenty-four patients: 16 were patients with chronic refractory pouchitis and eight, with a macroscopically and histologically normal ileal pouch, were considered as control subjects. Diagnosis of pouchitis was confirmed using the pouchitis disease activity index. All subjects were submitted to wireless capsule endoscopy procedure. Within 2 weeks before wireless capsule endoscopy, patients underwent a pouch endoscopy and a small bowel follow-through. Re-examination of the colonic surgical and histological specimens was also performed. RESULTS One patient with chronic pouchitis was excluded because of incomplete bowel cleaning. At small bowel follow-through of 16 patients, two subjects (13%) showed only a focal ectasia of the middle ileum and a substenosis of the pouch. At wireless capsule endoscopy all the 15 evaluable patients with chronic pouchitis (100%) showed diffuse lesions from duodenum to ileum consisting of aphthae, erosions, erythema, atrophy, cobblestone, deep/fissural ulcers. CONCLUSIONS This enteropathy needs further research, and wireless capsule endoscopy could be useful to show involvement of small bowel in patients with chronic pouchitis.

Abstract
BACKGROUND Pouchitis is the major long-term complication after ileal-pouch nal anastomosis for ulcerative colitis. Ten to 15% of patients develop a chronic pouchitis, either treatment responsive or treatment refractory. AIM To evaluate the efficacy of oral budesonide in inducing remission and improving quality of life in patients with chronic refractory pouchitis. METHODS Twenty consecutive patients with active pouchitis, not responding after 1 month of antibiotic treatment were treated with budesonide controlled ileal release 9 mg/day for 8 weeks. Symptomatic, endoscopic and histological evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of Pouchitis Disease Activity Index clinical score of < or = 2, endoscopic score of < or = 1 and total Pouchitis Disease Activity Index score of < or = 4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS Fifteen of 20 patients (75%) achieved remission. The median total Pouchitis Disease Activity Index scores before and after therapy were, respectively, 14 (range 9-16) and 3 (range 2-10) (P < 0.001). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 105 (range 77-175) to 180 (range 85-220) (P < 0.001). CONCLUSION Eight-week treatment with oral budesonide appears effective in inducing remission in patients with active pouchitis refractory to antibiotic treatment in this open-label study.

Abstract
OBJECTIVES When two auditory stimuli of different frequency are presented to each ear, binaural beats are perceived by the listener. The binaural beat frequency is equal to the difference between the frequencies applied to each ear. Our primary objective was to assess whether steady-state entrainment of electroencephalographic activity to the binaural beat occurs when exposed to a specific binaural beat frequency as has been hypothesized. Our secondary objective was to gather preliminary data on neuropsychologic and physiologic effects of binaural beat technology. DESIGN A randomized, blinded, placebo-controlled crossover experiment in 4 healthy adult subjects. INTERVENTION Subjects were randomized to experimental auditory stimulus of 30 minutes of binaural beat at 7 Hz (carrier frequencies: 133 Hz L; 140 Hz R) with an overlay of pink noise resembling the sound of rain on one session and control stimuli of the same overlay without the binaural beat carrier frequencies on the other session. OUTCOME MEASURES Data were collected during two separate sessions 1 week apart. Neuropsychologic and blood pressure data were collected before and after the intervention; electroencephalographic data were collected before, during, and after listening to either binaural beats or control. Neuropsychologic measures included State Trait Anxiety Inventory, Profile of Mood States, Rey Auditory Verbal List Test, Stroop Test, and Controlled Oral Word Association Test. Spectral and coherence analysis was performed on the electroencephalogram (EEG), and all measures were analyzed for changes between sessions with and without binaural beat stimuli. RESULTS There were no significant differences between the experimental and control conditions in any of the EEG measures. There was an increase of the Profile of Mood States depression subscale in the experimental condition relative to the control condition (p = 0.02). There was also a significant decrease in immediate verbal memory recall (p = 0.03) in the experimental condition compared to control condition. CONCLUSIONS We did not find support for steady-state entrainment of the scalp-recorded EEG while listening to 7-Hz binaural beats. Although our data indicated increased depression and poorer immediate recall after listening to binaural beats, larger studies are needed to confirm these findings.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) increases with age and elderly are more likely to develop severe disease. Older patients often complain of less severe or frequent heartburn than younger patients and they may present with atypical symptoms such as dysphagia, weight loss, or extraesophageal symptoms. Proton pump inhibitors (PPIs) are central in the management of GERD and are unchallenged with regards to their efficacy. They are considered safe and more effective than histamine receptor antagonists for healing esophagitis and for preventing its recurrence using a long term maintenance treatment. PPI have minimal side effects and few slight drug interactions and are considered safe for long term treatment. Pantoprazole is significantly effective both for acute and long-term treatment with excellent control of relapse and symptoms. It is well tolerated even for long-term therapy and its tolerability is optimal. Pantoprazole shows to have minimal interactions with other drugs because of a lower affinity for cytocrome P450 than older PPIs. Although the majority of elderly has concomitant illnesses and receive other drugs, this does not adversely effect the efficacy of pantoprazole because of its pharmacokinetics, which are independent of patient age. Clinical practice suggests that a low dose maintenance of PPIs should be used in older patients with GERD.

Abstract
OBJECTIVE To develop a model to direct the prescription of nutritional and botanical medicines in the treatment of type 2 diabetes for both clinical and research purposes. METHODS Available literature on nutritional and botanical medicines was reviewed and categorized as follows: antioxidant/anti-inflammatory; insulin sensitizer; and beta-cell protectant/insulin secretagogue. Literature describing laboratory assessment for glycemic control, insulin resistance, and beta-cell reserve was also reviewed and a clinical decision tree was developed. RESULTS Clinical algorithms were created to guide the use of nutritional and botanic medicines using validated laboratory measures of glycemic control, insulin sensitivity, and beta-cell reserve. Nutrient and botanic medicines with clinical trial research support include coenzyme Q10, carnitine, alpha-lipoic acid, N-acetylcysteine, vitamin D, vitamin C, vitamin E, chromium, vanadium, omega-3 fatty acids, cinnamon (Cinnamomum cassia), fenugreek (Trigonella foenum-graecum), and gymnema (Gymnema sylvestre). CONCLUSIONS Clinical algorithms can direct supplementation in clinical practice and provide research models for clinical investigation. Algorithms also provide a framework for integration of future evidence as it becomes available. Research funding to investigate potentially beneficial practices in complementary medicine is critically important for optimal patient care and safety.

Abstract
INTRODUCTION Binaural beat technology (BBT) products are sold internationally as personal development and health improvement tools. Producers suggest benefit from regular listening to binaural beats including reduced stress and anxiety, and increased focus, concentration, motivation, confidence, and depth in meditation. Binaural beats are auditory brainstem responses that originate in the superior olivary nucleus as a result of different frequency auditory stimuli provided to each ear. Listeners to binaural beat "hear" a beat at a frequency equal to the difference between the frequencies of the applied tones. OBJECTIVES The objectives of this pilot study were to gather preliminary data on psychologic and physiologic effects of 60 days daily use of BBT for hypothesis generation and to assess compliance, feasibility, and safety for future studies. DESIGN Uncontrolled pilot study. SUBJECTS Eight healthy adults participated in the study. INTERVENTION Participants listened to a CD with delta (0-4 Hz) binaural beat frequencies daily for 60 days. OUTCOME MEASURES Psychologic and physiological data were collected before and after a 60-day intervention. PSYCHOLOGIC: Depression (Beck Depression Inventory-2), anxiety (State-Trait Anxiety Inventory), mood (Profile of Mood States), absorption (Tellegen Absorption Scale) and quality of Life (World Health Organization-Quality of Life Inventory). PHYSIOLOGICAL: Cortisol, dehydroepiandrosterone, melatonin, insulin-like growth factor-1, serotonin, dopamine, epinephrine, norepinephrine, weight, blood pressure, high sensitivity C-reactive protein. RESULTS There was a decrease in trait anxiety (p = 0.004), an increase in quality of life (p = 0.03), and a decrease in insulin-like growth factor-1 (p = 0.01) and dopamine (p = 0.02) observed between pre- and postintervention measurements. CONCLUSIONS Binaural beat technology may exhibit positive effect on self-reported psychologic measures, especially anxiety. Further research is warranted to explore the effects on anxiety using a larger, randomized and controlled trial.

Abstract
PURPOSE Precancerous duodenal lesions in patients with familial adenomatous polyposis can be detected with duodenoscopy and treatment may prevent the development of cancer. We proposed to determine the frequency, natural history, cumulative risk, and risk factors of the precancerous duodenal lesions in a series of patients diagnosed in northern Italy. METHODS A prospective, endoscopic, follow-up protocol was performed in 50 patients examined by gastroduodenoscopy at two years of interval or less. The presence and severity of precancerous lesions of the duodenal mucosa were evaluated by Spigelman score. Twenty-five patients (50 percent) had proctocolectomy and ileoanal anastomosis, 15 (30 percent) had colectomy and ileorectal anastomosis, and 5 (10 percent) had proctocolectomy and definitive ileostomy from 0 to 3 years before the admission to the surveillance program. All patients showed more than a thousand adenomas in the colorectal mucosa. No patients with attenuated polyposis were found. RESULTS At the first endoscopy, duodenal adenomas could be detected in 19 of 50 patients (38 percent), whereas at the end of the follow-up, 43 (86 percent) had duodenal lesions. The final mean Spigelman score increased during the follow-up period (P<0.001 respect to baseline values). No duodenal cancer could be detected. Eleven patients had or developed severe precancerous duodenal lesions (Stage IV) treated with endoscopic or surgical resection. The distribution of patients with Stage IV according to the surgery of the colon was: 2 of 25 treated with ileoanal anastomosis and 8 of 15 with ileorectal anastomosis (P=0.0024, Fisher's exact test). CONCLUSIONS Patients with familial adenomatous polyposis are at risk of significant neoplasia. The natural history of precancerous lesions might be related to surgical treatment of colorectal neoplasms.

Abstract
Gastric cancer is the second most common cancer worldwide. The involvement of reactive oxygen species (ROS) in the pathogenesis of gastric malignancies is well known. Many human tumours have shown significant changes in the activity and expression of superoxide dismutase (SOD), which might be correlated with clinical-pathological parameters for the prognosis of human carcinoma. The aim of this study is the detection of MnSOD and CuZnSOD activity and their expression in gastric adenocarcinoma and healthy tissues. Gastric samples (adenocarcinoma and healthy tissues) harvested during endoscopy or resected during surgery were used to determine MnSOD and CuZnSOD activity and expression by spectrophotometric and Western blotting assays. The total SOD activity was significantly higher (p<0.05) in healthy mucosa with respect to gastric adenocarcinomas. No differences were found in MnSOD activity and, on the contrary, CuZnSOD activity was significantly lower (p<0.001) in cancer samples with respect to normal mucosa. The rate of MnSOD/CuZnSOD activity in adenocarcinoma was over ninefold higher than that registered in healthy tissues (p<0.05). Moreover, in adenocarcinoma MnSOD activity represented the 83% of total SOD with respect to healthy tissues where the ratio was 52% (p<0.001). On the contrary, in cancer tissues, CuZnSOD activity accounted for only 17% of the total SOD (p<0.001 if compared with the values recorded in normal mucosa). After immunoblotting, MnSOD was more expressed in adenocarcinoma with respect to normal mucosa (p<0.001), while CuZnSOD was similarly expressed in adenocarcinoma and healthy tissues. The SOD activity assay might provide a specific and sensitive method of analysis that allows the differentiation of healthy tissue from tumour tissue. The MnSOD to CuZnSOD activity ratio, and the ratio between these two isoforms and total SOD, presented in this preliminary study might be considered in the identification of cancerous from healthy control tissue.
