Rescue effect of curcumin against copper toxicity.

Turmeric has long been used not only as an indispensable part of Asian cuisine but as a medicinal herb for dressing wounds, bites, burns, treating eye infections and acne. Curcuminoids are the active substances and their synthetic derivatives (i.e. diacetylcurcumin (DAC) and metal-curcumin complexes) possess an incredibly wide range of medicinal properties that encompass chelation capacity for multiple heavy metals, antioxidant activity, anti-inflammatory properties, cytotoxicity against cancerous cells, antiviral and antibacterial effects, antihypertensive and insulin sensitizing role, and regulatory role on apoptosis. The aforementioned properties have put curcumin on spotlight as a potential treatment for ailments such as, hepatic diseases, neurodegenerative diseases, metabolic syndrome, dyslipidemia, cardiovascular disease, auto-immune diseases, malignancies and conditions associated with metal overload. Copper is essential for major biological functions, however, an excess causes chronic ailments including neurodegenerative disorders. The fascinating approach of curcumin could alleviate such effect by forming a complex. Thus, this review aims to present available data on the effect of copper-curcumin interaction in various in vitro, ex-vivo in vivo, and clinical studies.

Calcium and dairy products in the chemoprevention of colorectal adenomas: a systematic review and meta-analysis.

The risk of transition to colorectal cancer (CRC) in advanced colorectal adenomas (ACAs) is about 2.5 times higher than the non-advanced ones. This systematic review and meta-analysis was performed to determine the effect of calcium and dairy products on the incidence of CAs and ACAs. Six databases were systematically searched and 37 relevant clinical trials and observational studies involving over 10,964 cases were selected for inclusion. The results showed that calcium consumption reduced the risk of CAs incidence by 8% (RR: 0.92; 95% CI: 0.89-0.96), and calcium intake as a food and dairy product reduced it about 21% (RR: 0.79; 95% CI: 0.72-0.86), and 12% (RR: 0.88; 95% CI: 0.78-0.98), respectively. However, calcium supplementation did not show a significant effect on CAs incidence (RR: 0.97; 95% CI: 0.89-1.05). Results also revealed that total calcium intake markedly reduced the risk of ACAs (RR: 0.79; 95% CI: 0.73-0.85) and the risk of recurrence of adenomas about 12% (RR: 0.88; 95% CI: 0.84-0.93). Our results suggest that natural sources of calcium such as dairy products and foods may have more effective role than supplementary calcium in terms of reducing the risk of incidence and recurrence of colorectal adenomas and advanced adenomas.

Quality of life in inflammatory bowel disease patients: A cross-sectional study.

BACKGROUND: Inflammatory bowel disease (IBD) has a significant impact on health-related quality of life (HRQOL). This study aims to investigate the variables which can be attributed to HRQOL in IBD patients. MATERIALS AND METHODS: Seventy-one patients filled in IBD questionnaire (IBDQ-32), Pittsburgh sleep quality index questionnaire, and sociodemographic questionnaire. Disease activity was assessed by Crohn's disease activity index (CDAI) and ulcerative colitis activity index (UCAI). The correlations of sleep quality, sociodemographic variables, and disease characteristics with IBDQ were investigated. RESULTS: IBDQ-32 mean score was lower in patients who had hospitalization (P = 0.01), poor sleep quality (P < 0.001), anemia (P = 0.03), more severe disease (P = 0.01), and those who had not consumed folic acid (P = 0.01) relative to their counterparts. A multivariate regression analysis identified the predictors of decreased HRQOL as not consuming folic acid (P = 0.008), poor sleep quality (P = 0.014), and disease severity (P = 0.043). CONCLUSION: Impaired HRQOL was significantly associated with poor sleep quality, lack of folic acid consumption, and disease severity in IBD patients. Therefore, evaluation of folic acid level and efficacy of its supplementation in prospective studies is recommended. Treatment of sleep disturbance with pharmacological agents and nonpharmacological methods should be kept in mind as well.

Epidemioclinical Feature of Early-Onset Colorectal Cancer at-Risk for Lynch Syndrome in Central Iran.

BACKGROUND: Colorectal cancer (CRC) is becoming one of the most complicated challenges of human health, particularly in developing countries like Iran. In this paper, we try to characterize CRC cases diagnosed < age 50 at-risk for Lynch syndrome within central Iran. MATERIALS AND METHODS: We designed a descriptive retrospective study to screen all registered CRC patients within 2000-2013 in Poursina Hakim Research Center (PHRC), a referral gastroenterology clinic in central Iran, based on being early-onset (age at diagnosis ≤50 years) and Amsterdam II criteria. We calculated frequencies and percentages by SPSS 19 software to describe clinical and family history characteristics of patients with early-onset CRC. RESULTS: Overall 1,659 CRC patients were included in our study of which 413 (24.9%) were ≤50 years at diagnosis. Of 219/413 successful calls 67 persons (30.6%) were reported deceased. Family history was positive for 72/219 probands (32.9%) and 53 families (24.2%) were identified as familial colorectal cancer (FCC), with a history of at-least three affected members with any type of cancer in the family, of which 85% fulfilled the Amsterdam II Criteria as hereditary non-polyposis colorectal cancer (HNPCC) families (45/219 or 20.5%). Finally, 14 families were excluded due to proband tumor tissues being unavailable or unwillingness for incorporation. The most common HNPCC-associated extracolonic- cancer among both males and females of the families was stomach, at respectively 31.8 and 32.7 percent. The most common tumor locations among the 31 probands were rectum (32.3%), sigmoid (29.0%), and ascending colon (12.9%). CONCLUSIONS: Given the high prevalence of FCC (~1/4 of early-onset Iranian CRC patients), it is necessary to establish a comprehensive cancer genetic counseling and systematic screening program for early detection and to improve cancer prognosis among high risk families.

Comparing the efficacy of biofeedback and balloon-assisted training in the treatment of dyssynergic defecation.

BACKGROUND: Dyssynergic defecation does not respond appropriately to routine treatments for constipation. Recently, research has shown that biofeedback therapy is useful in anorectal dyssynergia. OBJECTIVE: To compare two treatment modalities for patients experiencing dyssynergic defecation. METHODS: Sixty-five subjects with dyssynergic defecation were recruited and randomly allocated to one of two treatment groups: balloon defecation training and biofeedback therapy. In the first group, a balloon was inserted into the rectum and inflated by water injection so that the patient experienced the sensation of a full rectum and, thus, the need to defecate. The patient was subsequently asked to reject the balloon. In the biofeedback group, the pen electrode of an electromyographic biofeedback device was inserted into the rectum, with the patient subsequently being asked to increase abdominal pressure and relax the rectal muscles accordingly. RESULTS: The findings showed a reduction in constipation in both groups. The ability to reject the balloon (volume and time) was significantly better in postintervention measurements; however, better results were found in the biofeedback arm of the study. Patient satisfaction after treatment reached 52% with balloon training and 79% in the biofeedback group. Reports of incomplete evacuation and the need for digit use during defecation remained constant after treatment in balloon-trained patients. CONCLUSION: Biofeedback training appeared to be superior to balloon defecation training and resulted in measurable changes in subjective and objective variables of dyssynergia.

Hypnotherapy as an adjuvant for the management of inflammatory bowel disease: a case report.

Idiopathic inflammatory bowel diseases (IBDs) significantly affect the quality of life of sufferers. Improved quality of life and patient symptom management may be achieved through integrating psychological/behavioral interventions with pharmacologic treatments. Here is our experience with hypnotherapy as an adjuvant management for an 18-year-old female with Crohn's Disease (CD) in remission (patient I) and a 24-year-old female with CD in active phase (patient II). The patients participated in 12 weekly one-hour sessions of hypnotherapy. Gut-directed, ego-strengthening, and post-hypnotic suggestions and immune-directed imaginations were used. After the hypnotherapy course, symptoms, psychological state, and quality of life improved in patient I, but not patient II (according to questionnaires). After a 6 month follow-up, symptoms and quality of life were the same as at the end of hypnotherapy sessions in both patients. The patients reported the greatest benefit of hypnotherapy was in helping them to cope better with their disease and also in improving their psychological state. Hypnotherapy may improve quality of life of IBD patients in remission and help them to cope better with their disease. Well-designed controlled clinical trials are needed in this field.

Endoscopic polypectomy resection of blue rubber bleb nevus lesions in small bowel.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by cutaneous and gastrointestinal (GI) venous malformations. The treatment of BRBNS is primarily supportive and ablative. Ablative therapy involves endoscopic or surgical treatment of GI venous malformations. We describe a 20-year-old woman who had multiple venous malformations all over the GI tract as well as cutaneous lesions. She had suffered from several episodes of melena, chronic anemia and fatigue for 10 years, which were treated temporarily by iron supplementation and blood transfusion. The endoscopic examination of the GI tract and total colonoscopy revealed multiple bluish sessile and polypoid venous malformations 2-3 cm in size throughout the GI tract. Argon plasma coagulation (APC) and polypectomy was done for all gastric and colonic lesions, respectively. Ileoscopy showed a large wide base vascular polypoid lesion at about 70 cm from the ileocecal valve with active bleeding; this was removed by snare polypectomy. One week later, she was discharged in good condition. At about 6 months' follow up she did not report any bleeding attack. Endoscopic polypectomy can be useful in patients with large and polypoid lesions of BRBNs which are not controlled with supportive therapy. Further experience is needed to evaluate the risks versus benefits of this approach.

How to put hypnosis into a placebo pill?

Many case studies and several controlled clinical trials have indicated the effectiveness of hypnotherapy for some medical conditions. However, because of methodological inadequacies hypnotherapy is still criticized for not having strong scientific evidence to support its claims. While randomized placebo-controlled clinical trial is generally accepted as the gold standard study design, creating a credible placebo control for hypnotherapy is a major challenge. This paper recommends "neutral hypnosis" as a credible placebo control for hypnotherapy trials.
