Query: A Treatment for Chronic Fatigue Syndrome
Epidemiological studies investigating the association between dietary intake and oesophageal cancer have mostly focused on nutrients and food groups instead of dietary patterns. We conducted a population-based case-control study, which included 365 oesophageal adenocarcinoma (OAC), 426 oesophagogastric junction adenocarcinoma (OGJAC) and 303 oesophageal squamous cell carcinoma (OSCC) cases, with frequency matched on age, sex and geographical location to 1580 controls. Data on demographic, lifestyle and dietary factors were collected using self-administered questionnaires. We used principal component analysis to derive three dietary patterns: 'meat and fat', 'pasta and pizza' and 'fruit and vegetable', and unconditional logistic regression models to estimate risks of OAC, OGJAC and OSCC associated with quartiles (Q) of dietary pattern scores. A high score on the meat-and-fat pattern was associated with increased risk of all three cancers: multivariable-adjusted OR 2·12 (95 % CI 1·30, 3·46) for OAC; 1·88 (95% CI 1·21, 2·94) for OGJAC; 2·84 (95% CI 1·67, 4·83) for OSCC (P-trend <0·01 for all three cancers). A high score on the pasta-and-pizza pattern was inversely associated with OSCC risk (OR 0·58, 95 % CI 0·36, 0·96, P for trend=0·009); and a high score on the fruit-and-vegetable pattern was associated with a borderline significant decreased risk of OGJAC (OR for Q4 v. Q1 0·66, 95% CI 0·42, 1·04, P=0·07) and significantly decreased risk of OSCC (OR 0·41, 95% CI 0·24, 0·70, P for trend=0·002). High-fat dairy foods appeared to play a dominant role in the association between the meat-and-fat pattern and risk of OAC and OGJAC. Further investigation in prospective studies is needed to confirm these findings.
Objective To determine the effect of fibre, antispasmodics, and peppermint oil in the treatment of irritable bowel syndrome. Design Systematic review and meta-analysis of randomised controlled trials. Data sources Medline, Embase, and the Cochrane controlled trials register up to April 2008. Review methods Randomised controlled trials comparing fibre, antispasmodics, and peppermint oil with placebo or no treatment in adults with irritable bowel syndrome were eligible for inclusion. The minimum duration of therapy considered was one week, and studies had to report either a global assessment of cure or improvement in symptoms, or cure of or improvement in abdominal pain, after treatment. A random effects model was used to pool data on symptoms, and the effect of therapy compared with placebo or no treatment was reported as the relative risk (95% confidence interval) of symptoms persisting. Results 12 studies compared fibre with placebo or no treatment in 591 patients (relative risk of persistent symptoms 0.87, 95% confidence interval 0.76 to 1.00). This effect was limited to ispaghula (0.78, 0.63 to 0.96). Twenty two trials compared antispasmodics with placebo in 1778 patients (0.68, 0.57 to 0.81). Various antispasmodics were studied, but otilonium (four trials, 435 patients, relative risk of persistent symptoms 0.55, 0.31 to 0.97) and hyoscine (three trials, 426 patients, 0.63, 0.51 to 0.78) showed consistent evidence of efficacy. Four trials compared peppermint oil with placebo in 392 patients (0.43, 0.32 to 0.59). Conclusion Fibre, antispasmodics, and peppermint oil were all more effective than placebo in the treatment of irritable bowel syndrome.
OBJECTIVES: Patients with chronic constipation due to food hypersensitivity (FH) had an elevated anal sphincter resting pressure. No studies have investigated a possible role of FH in anal fissures (AFs). We aimed to evaluate (1) the effectiveness of diet in curing AFs and to evaluate (2) the clinical effects of a double-blind placebo-controlled (DBPC) challenge, using cow's milk protein or wheat. METHODS: One hundred and sixty-one patients with AFs were randomized to receive a "true-elimination diet" or a "sham-elimination diet" for 8 weeks; both groups also received topical nifedipine and lidocaine. Sixty patients who were cured with the "true-elimination diet" underwent DBPC challenge in which cow's milk and wheat were used. RESULTS: At the end of the study, 69% of the "true-diet group" and 45% of the "sham-diet group" showed complete healing of AFs (P<0.0002). Thirteen of the 60 patients had AF recurrence during the 2-week cow's milk DBPC challenge and 7 patients had AF recurrence on wheat challenge. At the end of the challenge, anal sphincter resting pressure significantly increased in the patients who showed AF reappearance (P<0.0001), compared with the baseline values. The patients who reacted to the challenges had a significantly higher number of eosinophils in the lamina propria and intraepithelial lymphocytes than those who did not react to the challenges. CONCLUSIONS: An oligo-antigenic diet combined with medical treatment improved the rate of chronic AF healing. In more than 20% of the patients receiving medical and dietary treatment, AFs recurred on DBPC food challenge.
PURPOSE OF REVIEW: This review provides a comprehensive selection of the latest clinical trial results in antimigraine treatment. RECENT FINDINGS: The oral calcitonine gene-related peptide antagonist telcagepant is efficacious in acute treatment. Compared to triptans, its efficacy is almost comparable but its tolerance is superior. The same is true for the 5HT-1F agonist lasmiditan, another agent devoid of vascular effects. Triptans, as other drugs, are more efficient if taken early but nonsteroidal anti-inflammatory drugs and analgesics remain useful for acute treatment, according to several meta-analyses. Single-pulse transcranial magnetic stimulation during the aura rendered more patients pain-free (39%) than sham stimulation (22%) in one study. Topiramate could be effective for migrainous vertigo, but it did not prevent transformation to chronic migraine in patients with high attack frequency. Onabotulinumtoxin A was effective for chronic migraine and well tolerated, but the therapeutic gain over placebo was modest; the clinical profile of responders remains to be determined before widespread use. Occipital nerve stimulation was effective in intractable chronic migraine with 39% of responders compared to 6% after sham stimulation. This and other neuromodulation techniques, such as sphenopalatine ganglion stimulation, are promising treatments for medically refractory patients but large controlled trials are necessary. One study suggests that outcome of patent foramen ovale closure in migraine might depend on anatomic and functional characteristics. SUMMARY: Drugs with a better efficacy or side-effect profile than triptans may soon become available for acute treatment. The future may also look brighter for some of the very disabled chronic migraineurs thanks to novel drug and neuromodulation therapies.
Cisapride is a substituted benzamide compound that stimulates motor activity in all segments of the gastrointestinal tract by enhancing the release of acetylcholine from the enteric nervous system. Cisapride is administered orally in the treatment of gastro-oesophageal reflux disease, functional dyspepsia, gastroparesis, chronic intestinal pseudo-obstruction syndromes and chronic constipation. In gastro-oesophageal reflux disease in both adults and children, cisapride provides symptomatic improvement and mucosal healing. Long term treatment with cisapride is effective in the prevention of relapse of oesophagitis. Cisapride improves gastric emptying rates and improves symptoms in patients with gastroparesis of various origins. Unlike domperidone and metoclopramide, long term administration of cisapride seems to result in persistently enhanced gastric emptying. Cisapride is also effective in improving symptoms in patients with functional dyspepsia. In comparative studies in patients with functional dyspepsia, cisapride was at least as effective as metoclopramide, domperidone, clebopride, ranitidine and cimetidine. Cisapride increases stool frequency and reduces laxative consumption in patients with idiopathic constipation. Severe cases of slow transit constipation seem refractory to cisapride. Clinical studies also indicate that cisapride might be effective in the treatment of chronic intestinal pseudo-obstruction, postoperative ileus, peptic ulcer and irritable bowel syndrome. Further clinical studies are warranted to define the role of cisapride in these conditions. The dosage of cisapride ranges from 5mg 3 times daily to 20mg twice daily. Cisapride is generally well tolerated, both during short and long term treatment. In children, cisapride is also well tolerated in doses of 0.2 to 0.3 mg/kg, 3 to 4 times daily.(ABSTRACT TRUNCATED AT 250 WORDS)
Objective: Epidemiologic studies consistently link caffeine, a nonselective adenosine antagonist, to lower risk of Parkinson disease (PD). However, the symptomatic effects of caffeine in PD have not been adequately evaluated. Methods: We conducted a 6-week randomized controlled trial of caffeine in PD to assess effects upon daytime somnolence, motor severity, and other nonmotor features. Patients with PD with daytime somnolence (Epworth >10) were given caffeine 100 mg twice daily ×3 weeks, then 200 mg twice daily ×3 weeks, or matching placebo. The primary outcome was the Epworth Sleepiness Scale score. Secondary outcomes included motor severity, sleep markers, fatigue, depression, and quality of life. Effects of caffeine were analyzed with Bayesian hierarchical models, adjusting for study site, baseline scores, age, and sex. Results: Of 61 patients, 31 were randomized to placebo and 30 to caffeine. On the primary intention-to-treat analysis, caffeine resulted in a nonsignificant reduction in Epworth Sleepiness Scale score (−1.71 points; 95% confidence interval [CI] −3.57, 0.13). However, somnolence improved on the Clinical Global Impression of Change (+0.64; 0.16, 1.13, intention-to-treat), with significant reduction in Epworth Sleepiness Scale score on per-protocol analysis (−1.97; −3.87, −0.05). Caffeine reduced the total Unified Parkinson's Disease Rating Scale score (−4.69 points; −7.7, −1.6) and the objective motor component (−3.15 points; −5.50, −0.83). Other than modest improvement in global health measures, there were no changes in quality of life, depression, or sleep quality. Adverse events were comparable in caffeine and placebo groups. Conclusions: Caffeine provided only equivocal borderline improvement in excessive somnolence in PD, but improved objective motor measures. These potential motor benefits suggest that a larger long-term trial of caffeine is warranted. Classification of evidence: This study provides Class I evidence that caffeine, up to 200 mg BID for 6 weeks, had no significant benefit on excessive daytime sleepiness in patients with PD.
OBJECTIVE: The aim of this double-blind and placebo-controlled trial was to investigate whether saffron (stigma of Crocus sativus L.) could relieve symptoms of premenstrual syndrome (PMS). DESIGN: Double-blind, randomised and placebo-controlled trial. SETTING: Departments of Gynaecology/Obstetrics and Psychiatry, Tehran and Zanjan University of Medical Sciences. POPULATION: Women aged 20-45 years with regular menstrual cycles and experience of PMS symptoms for at least 6 months were eligible for the study. METHOD: Women were randomly assigned to receive capsule saffron 30 mg/day (15 mg twice a day; morning and evening) (group A) or capsule placebo (twice a day) for a two menstrual cycles (cycles 3 and 4). MAIN OUTCOME MEASURES: The primary outcome measure was the Daily Symptom Report, and secondary outcome measure was the Hamilton Depression Rating Scale. RESULTS: In this trial, saffron was found to be effective in relieving symptoms of PMS. A significant difference was observed in efficacy of saffron in cycles 3 and 4 in the Total Premenstrual Daily Symptoms and Hamilton Depression Rating Scale. CONCLUSION: The results of this study indicate the efficacy of C. sativus L. in the treatment of PMS. However, a tolerable adverse effects profile of saffron may well confirm the application of saffron as an alternative treatment for PMS. These results deserved further investigations.
Clinical experience suggests that fasting followed by vegetarian diet may help patients with rheumatoid arthritis (RA). We reviewed the available scientific evidence, because patients frequently ask for dietary advice, and exclusive pharmacological treatment of RA is often not satisfying. Fasting studies in RA were searched in MEDLINE and by checking references in relevant reports. The results of the controlled studies which reported follow-up data for at least three months after fasting were quantitatively pooled. Thirty-one reports of fasting studies in patients with RA were found. Only four controlled studies investigated the effects of fasting and subsequent diets for at least three months. The pooling of these studies showed a statistically and clinically significant beneficial long-term effect. Thus, available evidence suggests that fasting followed by vegetarian diets might be useful in the treatment of RA. More randomised long-term studies are needed to confirm this view by methodologically convincing data.
Mastalgia affects up to two-thirds of women at some time during their reproductive lives. It is usually benign, but thefear of underlying breast cancer is why many women present for evaluation. Mastalgia can be associated with premenstrual syndrome, fibrocystic breast disease, psychologic disturbance and, rarely, breast cancer. Occasionally, extramammary conditions, like Tietzie syndrome, present as mastalgia. A thorough clinical evaluation is required to assess the cause. The majority of women can be reassured after a clinical evaluation. Approximately 15% require pain-relieving therapy. Mechanical breast support; a low-fat, high-carbohydrate diet; and topical nonsteroidal antiinflammatory agents are reasonable first-line treatments. Hormonal agents, such as bromocriptine, tamoxifen and danazol, have all demonstrated efficacy in the treatment of mastalgia. Side effects, however, limit their extensive use. Danazol is the only FDA-approved hormonal treatment and is best used in cyclic form to limit the adverse effects. Lisuride maleate is a new agent recently studied for the treatment of mastalgia. Initial data on this medication are encouraging. Sixty percent of cyclic mastalgia recurs after treatment. Noncyclic mastalgia responds poorly to treatment but resolves spontaneously in up to 50% of cases.
BACKGROUND: Irritable bowel syndrome (IBS) is a complex syndrome that is difficult to manage. Here we present the evidence supporting medication treatments for specific IBS symptoms, discuss evidence-based management of IBS with medications including dose regimens and adverse effects and review progress on research for new IBS treatments. SUMMARY: Currently, there is evidence to support improvements in specific IBS symptoms following treatment with loperamide, psyllium, bran, lubiprostone, linaclotide, amitriptyline, trimipramine, desipramine, citalopram, fluoxetine, paroxetine, dicyclomine, peppermint oil, rifaximin, ketotifen, pregabalin, gabapentin and octreotide and there are many new medications being investigated for the treatment of IBS. Key Message: Of the medications with demonstrated improvements for IBS symptoms, rifaximin, lubiprostone, linaclotide, fiber supplementation and peppermint oil have the most reliable evidence supporting their use for the treatment of IBS. Onset of efficacy for the various medications has been noted to be as early as 6 days after initiation; however, the efficacy of most medications was not assessed prospectively at predefined periods. Additional studies of currently available and new medications are ongoing and are needed to better define their place in therapy and expand therapeutic options for the treatment of IBS. The most promising new medications for IBS include a variety of novel pharmacologic approaches, most notably the dual μ-opioid receptor agonist and δ-opioid antagonist, JNJ-27018966. © 2014 S.

Fasting is an effective treatment for rheumatoid arthritis, but most patients relapse on reintroduction of food. The effect of fasting followed by one year of a vegetarian diet was assessed in a randomised, single-blind controlled trial. 27 patients were allocated to a four-week stay at a health farm. After an initial 7-10 day subtotal fast, they were put on an individually adjusted gluten-free vegan diet for 3.5 months. The food was then gradually changed to a lactovegetarian diet for the remainder of the study. A control group of 26 patients stayed for four weeks at a convalescent home, but ate an ordinary diet throughout the whole study period. After four weeks at the health farm the diet group showed a significant improvement in number of tender joints, Ritchie's articular index, number of swollen joints, pain score, duration of morning stiffness, grip strength, erythrocyte sedimentation rate, C-reactive protein, white blood cell count, and a health assessment questionnaire score. In the control group, only pain score improved score. In the control group, only pain score improved significantly. The benefits in the diet group were still present after one year, and evaluation of the whole course showed significant advantages for the diet group in all measured indices. This dietary regimen seems to be a useful supplement to conventional medical treatment of rheumatoid arthritis.
In this study, the effects of a diet rich in insoluble fiber (DRIF) on motor disability and the peripheral pharmacokinetics of orally administered L-dopa in Parkinsonian patients with marked constipation are analyzed. We found a useful effect of a DRIF on plasma L-dopa concentration and motor function. The greatest effect on the plasma L-dopa levels was found early (at 30 and 60 min) after oral administration. There was a relationship between the improvement of constipation and the higher bioavailability of L-dopa. DRIF can be a coadjuvant treatment in patients with Parkinson's disease.
RATIONALE: There is increasing evidence to suggest the possible efficacy of Crocus sativus (saffron) in the management of Alzheimer's disease (AD). OBJECTIVE: The purpose of the present investigation was to assess the efficacy of C. sativus in the treatment of patients with mild-to-moderate AD. METHODS: Fifty-four Persian-speaking adults 55 years of age or older who were living in the community were eligible to participate in a 22-week, double-blind study of parallel groups of patients with AD. The main efficacy measures were the change in the Alzheimer's Disease Assessment Scale-cognitive subscale and Clinical Dementia Rating Scale-Sums of Boxes scores compared with baseline. Adverse events (AEs) were systematically recorded. Participants were randomly assigned to receive a capsule saffron 30 mg/day (15 mg twice per day) or donepezil 10 mg/day (5 mg twice per day). RESULTS: Saffron at this dose was found to be effective similar to donepezil in the treatment of mild-to-moderate AD after 22 weeks. The frequency of AEs was similar between saffron extract and donepezil groups with the exception of vomiting, which occurred significantly more frequently in the donepezil group. CONCLUSION: This phase II study provides preliminary evidence of a possible therapeutic effect of saffron extract in the treatment of patients with mild-to-moderate Alzheimer's disease. This trial is registered with the Iranian Clinical Trials Registry (IRCT138711051556N1).
Until recently, intact protein that is rich in tryptophan was not seen as an alternative to pharmaceutical-grade tryptophan because protein also contains large neutral amino acids (LNAAs) that compete for transport sites across the blood-brain barrier. Recent evidence indicates that when deoiled gourd seed (a rich source of tryptophan with approximately 22 mg/g protein) is combined with glucose (a carbohydrate that reduces serum levels of competing LNAAs) a clinical effect similar to that of pharmaceutical-grade tryptophan is achieved. Objective and subjective measures of anxiety in those suffering from social phobia (also known as social anxiety disorder) were employed to measure changes in anxiety in response to a stimulus as part of a double-blind, placebo-controlled, crossover study with a wash-out period of 1 week between study sessions. Subjects were randomly assigned to start with either (i) protein-source tryptophan (deoiled gourd seed) in combination with carbohydrate or (ii) carbohydrate alone. One week after the initial session, subjects returned for a follow-up session and received the opposite treatment of that received at the first session. All 7 subjects who began the study completed the 2-week protocol. Protein-source tryptophan with carbohydrate, but not carbohydrate alone, resulted in significant improvement on an objective measure of anxiety. Protein-source tryptophan combined with a high glycemic carbohydrate is a potential anxiolytic to those suffering from social phobia.
This article reviews the existing literature on fibromyalgia (FM) and diet, discusses the possible role of diet on central sensitization in FM, proposes a novel hypothesis of possible food-related contributors to central sensitization, and makes recommendations for future dietary research directions.
A few patients remain severely affected by atopic dermatitis into adult life despite treatment with systemic steroids, azathioprine, and photochemotherapy. 33 patients took part in a double-blind, placebo-controlled, crossover study to assess the efficacy and safety of cyclosporin (5 mg/kg per day) in adults with severe refractory atopic dermatitis. Treatments were given for eight weeks each with one group (n = 16) receiving placebo followed by cyclosporin and another (n = 17) receiving cyclosporin and then placebo. Disease activity, extent of disease, sleep and itch, topical steroid use, and adverse events were assessed every two weeks. Both extent and activity of dermatitis were significantly improved (p less than 0.001) as were subjective measures of disease. 20 patients receiving cyclosporin reported adverse events compared with 8 taking placebo, although no patient required withdrawal from the study. Cyclosporin therapy led to an increase in the mean serum urea, creatinine, and bilirubin concentrations, although only the rise in bilirubin was significant (p = 0.001). Our results confirm that cyclosporin is a safe and effective short-term treatment for severe, refractory atopic dermatitis.
Many people suffer from fibromyalgia (FM) without an effective treatment. They do not have a good quality of life and cannot maintain normal daily activity. Among the different hypotheses for its ethiopathophysiology, oxidative stress is one of the possibilities. Non-scientific information addressed to patients regarding the benefits of nutrition is widely available, and they are used to trying non-evidenced strategies. The aim of this paper is to find out what we know right now from scientific studies regarding fibromyalgia disease and nutritional status, diets and food supplements. A systematic search has been performed on Medline with a wide range of terms about these nutritional issues. The search has been made during 2009, for articles published between 1998 and 2008. TARGET POPULATION: people suffering from FM. Vegetarian diets could have some beneficial effects probably due to the increase in antioxidant intake. There is a high prevalence of obesity and overweight in patients, and weight control seems to be an effective tool to improve the symptoms. Some nutritional deficiencies have been described, it is not clear whether they are directly related to this disease or not. About the usefulness of some food supplements we found very little data, and it seems that more studies are needed to prove which ones could be of help. Dietary advice is necessary to these patients to improve their diets and maintain normal weight. It would be interesting to investigate more in the field of nutrition and FM to reveal any possible relationships.
Gastroenterologists are often faced with the diagnostic problem of differentiating acute symptoms of ulcerative colitis from functional intestinal disorders. Bowel obsession syndrome (BOS) is an OCD-like, functional syndrome characterized by fear of fecal incontinence and compulsive behaviors of evacuation-checking. Only sparse case studies on treatment of BOS with antidepressants have been published. This is the first study on successful psychotherapy of a male patient with ulcerative colitis overlapping functional bowel symptoms and marked symptoms of BOS. Clinical recognition of BOS may help clinicians in differential diagnosis, prevent unnecessary investigations, and give patients the most appropriate treatment.
WHAT IS KNOWN: Herbal medicines have been used in the treatment of behavioural and psychological symptoms of dementia but with variable response. Crocus sativus (saffron) may inhibit the aggregation and deposition of amyloid β in the human brain and may therefore be useful in Alzheimer's disease (AD). OBJECTIVE: The goal of this study was to assess the efficacy of saffron in the treatment of mild to moderate AD. METHODS: Forty-six patients with probable AD were screened for a 16-week, double-blind study of parallel groups of patients with mild to moderate AD. The psychometric measures, which included AD assessment scale-cognitive subscale (ADAS-cog), and clinical dementia rating scale-sums of boxes, were performed to monitor the global cognitive and clinical profiles of the patients. Patients were randomly assigned to receive capsule saffron 30 mg/day (15 mg twice per day) (Group A) or capsule placebo (two capsules per day) for a 16-week study. RESULTS: After 16 weeks, saffron produced a significantly better outcome on cognitive function than placebo (ADAS-cog: F=4·12, d.f.=1, P=0·04; CDR: F=4·12, d.f.=1, P=0·04). There were no significant differences in the two groups in terms of observed adverse events. WHAT IS NEW AND CONCLUSION: This double-blind, placebo-controlled study suggests that at least in the short-term, saffron is both safe and effective in mild to moderate AD. Larger confirmatory randomized controlled trials are called for. Copyright © 2010 The Authors. JCPT © 2010 Blackwell Publishing Ltd.
Dry-eye syndrome (DES) is a multifactorial disease affecting millions of individuals worldwide. Various factors, including age, hormonal status, genetics, sex, immune status, innervation status, nutrition, pathogens, and environmental stress, can alter the cellular and molecular structure or function of components of the ocular surface system. The resulting imbalance increases susceptibility to desiccation and epithelial damage, leading to a vicious circle in which inflammation amplifies and sustains further damage by chronic deregulation of the system. Lubricating agents and steroids have been used as treatment options. However, as the causes of the disease become better elucidated, the more chemically complex cyclosporine A has become an increasingly useful treatment option and in the United States is currently the only Food and Drug Administration (FDA)-approved prescription drug for the treatment of dry eye. The safety and efficacy of cyclosporine have been shown in numerous studies.
BACKGROUND: Chronic cutaneous complications such as pruritus are among the very frequent complaints of sulphur mustard (SM)-exposed patients. The present trial investigated the impact of curcumin on serum inflammatory biomarkers and their association with pruritus severity and quality of life (QoL). METHODS: This was a randomized, double-blind trial among 96 male Iranian veterans (age 37-59 y) who were suffering from chronic SM-induced pruritic skin lesions. Patients were randomly assigned to curcumin (1 g/d, n = 46) or placebo (n = 50) for four weeks. Serum concentrations of interleukins 6 (IL-6) and 8 (IL-8) together with high-sensitivity C-reactive protein (hs-CRP) and calcitonin gene-related peptide (CGRP) were measured at baseline and at the end of the trial. Assessment of pruritus severity was performed using the pruritus score and QoL using the Dermatology Life Quality Index (DLQI). RESULTS: Serum IL-8 and hs-CRP were significantly reduced in both groups but the magnitude of reduction was greater in the curcumin group (P < 0.001). Serum CGRP was only decreased in the curcumin group (P < 0.001). No significant change was observed in serum IL-6. There were significant correlations between CGRP and IL-6 changes (P = 0.011) and between DLQI and IL-8 changes (P = 0.026) in the curcumin group. In the curcumin group, changes in serum IL-8 concentrations were found as the significant predictor of DLQI scores (P = 0.026) but none of the independent variables could predict pruritus scores. CONCLUSIONS: Curcumin supplementation effectively mitigates inflammation in patients suffering from chronic SM-induced cutaneous complications. This anti-inflammatory effect might account for the observed pruritus alleviation and QoL improvement by this phytochemical.
BACKGROUND: The use of nasal irrigation for the treatment of nose and sinus complaints has its foundations in yogic and homeopathic traditions. There has been increasing use of saline irrigation, douches, sprays and rinsing as an adjunct to the medical management of chronic rhinosinusitis. Treatment strategies often include the use of topical saline from once to more than four times a day. Considerable patient effort is often involved. Any additional benefit has been difficult to discern from other treatments. OBJECTIVES: To evaluate the effectiveness and safety of topical saline in the management of chronic rhinosinusitis. SEARCH STRATEGY: Our search included the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4 2006), MEDLINE (1950 to 2006) and EMBASE (1974 to 2006). The date of the last search was November 2006. SELECTION CRITERIA: Randomised controlled trials in which saline was evaluated in comparison with either no treatment, a placebo, as an adjunct to other treatments or against treatments. The comparison of hypertonic versus isotonic solutions was also compared. DATA COLLECTION AND ANALYSIS: Trials were graded for methodological quality using the Cochrane approach (modification of Chalmers 1990). Only symptom scores from saline versus no treatment and symptom and radiological scores from the hypertonic versus isotonic group could be pooled for statistical analysis. A narrative overview of the remaining results is presented. MAIN RESULTS: Eight trials were identified that satisfied the inclusion criteria. Three studies compared topical saline against no treatment, one against placebo, one as an adjunct to and one against an intranasal steroid spray. Two studies compared different hypertonic solutions against isotonic saline. There is evidence that saline is beneficial in the treatment of the symptoms of chronic rhinosinusitis when used as the sole modality of treatment. Evidence also exists in favour of saline as a treatment adjunct. No superiority was seen when saline was compared against a reflexology 'placebo'. Saline is not as effective as an intranasal steroid. Some evidence suggests that hypertonic solutions improve objective measures but the impact on symptoms is less clear. AUTHORS' CONCLUSIONS: Saline irrigations are well tolerated. Although minor side effects are common, the beneficial effect of saline appears to outweigh these drawbacks for the majority of patients. The use of topical saline could be included as a treatment adjunct for the symptoms of chronic rhinosinusitis.
The objective of this study was to evaluate, in a phase 2 pilot study, tolerability and the effect of 6 weeks of flaxseed therapy on hot flash scores in women not wishing to receive estrogen therapy. Eligibility included 14 hot flashes per week for at least 1 month. In the baseline week, participants took no study medication and documented the characteristics of their hot flashes. Thereafter, crushed flaxseed was administered at 40 g daily. Participants provided weekly toxicity reports and health-related quality of life information. The primary end point was a change in hot flash score prospectively reported in a daily hot flash diary. Thirty women were enrolled between June 17 and November 8, 2005. The mean decrease in hot flash scores after flaxseed therapy was 57% (median decrease 62%). The mean reduction in daily hot flash frequency was 50% (median reduction 50%), from 7.3 hot flashes to 3.6. Fourteen of the 28 participants (50%) experienced mild or moderate abdominal distention. Eight participants (29%) experienced mild diarrhea, one experienced flatulence, and six (21%) withdrew because of toxicities. This study suggests that dietary therapy decreases hot flash activity in women not taking estrogen therapy. This reduction is greater than what would be expected with placebo.
Many patients with atopic dermatitis are dissatisfied with conventional treatments based on topical steroids and have experienced some traditional remedies and alternative therapies. However, most of such therapies have not been evaluated scientifically and clinically by specialists. This study was designed to assess whether a certain vegetarian diet might be effective for atopic dermatitis and if so, to identify the mechanisms of this remedy through analyses of immunological parameters. An open-trial study was carried out in twenty patients with atopic dermatitis. An improvement of dermatitis was evaluated by SCORAD index and serological and immunological parameters were monitored. After a two-month treatment, the severity of dermatitis was strikingly inhibited, as assessed by SCORAD index and serological parameters including LDH5 activity and a number of peripheral eosinophils. A sharp reduction in eosinophils and neutrophils was observed prior to improvement in the skin inflammation. In addition, PGE2 production by peripheral blood mononuclear cells was reduced by this treatment. In contrast, serum IgE levels did not change during the same period. Although this study is an open-trial one, it suggests that this treatment may be useful for the treatment of adult patients with severe atopic dermatitis.
21 patients with severe persistent cyclical mastopathy of at least 5 years' duration were randomised to a control group who received general dietary advice or to an intervention group who were taught how to reduce the fat content of their diet to 15% of calories while increasing complex carbohydrate consumption to maintain caloric intake. Both groups were followed for 6 months with food records and measurement of plasma hormone and lipid levels. Severity of symptoms was recorded with daily diaries and patients were assessed at the beginning and end of the study by a physician who was unaware of their dietary regimen. After 6 months there was a significant reduction in the intervention group in the severity of premenstrual breast tenderness and swelling. Physical examination showed reduced breast swelling, tenderness, and nodularity in 6 of 10 patients in the intervention group and 2 of 9 patients in the control group.
