Improved work productivity and health-related quality of life in patients with irritable bowel syndrome with diarrhea receiving eluxadoline following inadequate response to loperamide.

BACKGROUND: Irritable bowel syndrome with diarrhea (IBS-D) is a chronic disorder of gut-brain interaction that negatively affects work productivity and health-related quality of life (HRQOL). IBS-D therapeutic options are limited and include loperamide, an over-the-counter µ-opioid receptor agonist commonly used as an antidiarrheal agent, and eluxadoline, a mixed µ- and κ-opioid receptor agonist and δ-opioid receptor antagonist approved in the United States for the treatment of IBS-D in adults. OBJECTIVE: To characterize the effect of eluxadoline on work productivity and HRQOL in patients with IBS-D with previous inadequate response to loperamide. METHODS: The Work Productivity and Activity Impairment Questionnaire for IBS-D (WPAI:IBS-D), Centers for Disease Control and Prevention Healthy Days Core Module (CDC HRQOL-4), and EuroQoL-5 Dimension (EQ-5D) instruments were administered at baseline and week 12 of a phase 4 clinical trial (RELIEF), assessing the efficacy and safety of eluxadoline treatment in adults with IBS-D reporting previous inadequate response to loperamide. Changes from baseline to week 12 for each assessment were evaluated using an analysis of covariance model. Indirect costs were calculated by converting overall work productivity losses into monetary values. RESULTS: A total of 346 patients were randomized to either eluxadoline (n = 172) or placebo (n = 174). From baseline to week 12, compared with placebo, twice-daily treatment with eluxadoline resulted in significantly greater reductions in absenteeism (2.6%; P = 0.046). Numerically greater decreases in presenteeism, overall work productivity loss, and daily activity impairment were also observed in patients receiving eluxadoline compared with those receiving placebo (P = not significant for each). Numerical reductions in overall work productivity loss from baseline to week 12 translate to approximately 2.4 hours per patient per week (123 hours annually) and correspond to an avoided overall work loss of $4,503 annually for an employee with IBS-D treated with eluxadoline. In addition, from baseline to week 12, treatment with eluxadoline led to a significantly greater reduction in the number of unhealthy days experienced (-1.7 days; P = 0.042), as well as numerical improvements in EQ-5D measures in comparison with placebo (P = not significant for each). CONCLUSIONS: In patients with IBS-D reporting inadequate response to loperamide, eluxadoline treatment was associated with significant reductions in absenteeism and the number of unhealthy days experienced. Eluxadoline treatment of IBS-D may lead to significant cost savings via mitigation of losses in work productivity.

Study on the clinical mechanism of Tong-Xie-An-Chang Decoction in the treatment of diarrheal irritable bowel syndrome based on single-cell sequencing technology.

BACKGROUND: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a kind of functional gastrointestinal disorder with obscure pathogenesis, and exploration about differential gene expression and cell heterogeneity of T lymphocytes in peripheral blood in IBS-D patients still remains unknown. Clinicians tend to use symptomatic treatment, but the efficacy is unstable and symptoms are prone to relapse. Traditional Chinese Medicine (TCM) is used frequently in IBS-D with stable and lower adverse effects. Tong-Xie-An-Chang Decoction (TXACD) has been proven to be effective in the treatment of IBS-D. However, the underlying therapeutic mechanism remains unclear. This trial aims to evaluate the clinical efficacy and safety of TXACD in IBS-D and elucidate the gene-level mechanism of IBS-D and therapeutic targets of TXACD based on single-cell sequencing technology. METHODS/DESIGN: This is a randomized controlled, double-blind, double-simulation clinical trial in which 72 eligible participants with IBS-D and TCM syndrome of liver depression and spleen deficiency will be randomly allocated in the ratio of 1:1 to two groups: the experimental group and the control group. The experimental group receives Tong-Xie-An-Chang Decoction (TXACD) and Pinaverium bromide tablets placebo; the control group receives pinaverium bromide tablets and TXACD placebo. Each group will be treated for 4 weeks. The primary outcome: the rate of IBS-Symptom Severity Score (IBS-SSS). The secondary outcomes: TCM syndrome score, adequate relief and IBS-Quality of Life Questionnaire (IBS-QOL). Mechanistic outcome is the single-cell sequencing profiling of the T lymphocytes in peripheral blood from IBS-D participants before and after the treatment and healthy individuals. DISCUSSION: This trial will prove the efficacy and safety of TXACD with high-quality evidence and provide a comprehensive perspective on the molecular mechanism of IBS-D by single-cell sequencing profiling, which makes us pinpoint specific biomarkers of IBS-D and therapeutic targets of TXACD.

Yoga for Teens With Irritable Bowel Syndrome: Results From a Mixed-Methods Pilot Study.

Irritable bowel syndrome (IBS) is a common condition associated with recurrent abdominal pain and altered bowel habits. It is particularly pernicious to youth, who may withdraw from life tasks due to pain, diarrhea, and/or fear of symptoms. Emotional stress exacerbates IBS symptoms, and mind-body interventions may be beneficial. In this mixed-methods study of 18 teens aged 14 to 17 years undertaking a 6-week Iyengar yoga intervention, we aimed to identify treatment responders and to explore differences between responders and nonresponders on a range of quantitative outcomes and qualitative themes related to yoga impact, goodness of fit, and barriers to treatment. Half of the teens responded successfully to yoga, defined as a clinically meaningful reduction in abdominal pain. Responders differed from nonresponders on postintervention quantitative outcomes, including reduced abdominal pain, improved sleep, and increased visceral sensitivity. Qualitative outcomes revealed that responders reported generalized benefits early in treatment and that their parents were supportive and committed to the intervention. Responders and nonresponders alike noted the importance of home practice to achieve maximal, sustained benefits. This study reveals the need for developmentally sensitive yoga programs that increase accessibility of yoga for all patients.

Inhibitory effects of patchouli alcohol on stress-induced diarrhea-predominant irritable bowel syndrome.

AIM: To elucidate the mechanism of patchouli alcohol (PA) in treatment of rat models of diarrhea-predominant irritable bowel syndrome (IBS-D). METHODS: We studied the effects of PA on colonic spontaneous motility using its cumulative log concentration (3 × 10-7 mol/L to 1 × 10-4 mol/L). We then determined the responses of the proximal and distal colon segments of rats to the following stimuli: (1) carbachol (1 × 10-9 mol/L to 1 × 10-5 mol/L); (2) neurotransmitter antagonists including Nω-nitro-L-arginine methyl ester hydrochloride (10 µmol/L) and (1R*, 2S*)-4-[2-Iodo-6-(methylamino)-9H-purin-9-yl]-2-(phosphonooxy)bicyclo[3.1.0]hexane-1-methanol dihydrogen phosphate ester tetraammonium salt (1 µmol/L); (3) agonist α,ß-methyleneadenosine 5'-triphosphate trisodium salt (100 µmol/L); and (4) single KCl doses (120 mmol/L). The effects of blockers against antagonist responses were also assessed by pretreatment with PA (100 µmol/L) for 1 min. Electrical-field stimulation (40 V, 2-30 Hz, 0.5 ms pulse duration, and 10 s) was performed to observe nonadrenergic, noncholinergic neurotransmitter release in IBS-D rat colon. The ATP level of Kreb's solution was also determined. RESULTS: PA exerted a concentration-dependent inhibitory effect on the spontaneous contraction of the colonic longitudinal smooth muscle, and the half maximal effective concentration (EC50) was 41.9 µmol/L. In comparison with the KCl-treated IBS-D group, the contractile response (mg contractions) in the PA + KCl-treated IBS-D group (11.87 ± 3.34) was significantly decreased in the peak tension (P < 0.01). Compared with CCh-treated IBS-D rat colon, the cholinergic contractile response of IBS-D rat colonic smooth muscle (EC50 = 0.94 µmol/L) was significantly decreased by PA (EC50 = 37.43 µmol/L) (P < 0.05). Lack of nitrergic neurotransmitter release in stress-induced IBS-D rats showed contraction effects on colonic smooth muscle. Pretreatment with PA resulted in inhibitory effect on L-NAME-induced (10 µmol/L) contraction (P < 0.05). ATP might not be the main neurotransmitter involved in inhibitory effects of PA in the colonic relaxation of stress-induced IBS-D rats. CONCLUSION: PA application may serve as a new therapeutic approach for IBS-D.

Therapeutic Effect of Chang'an I Recipe ( I ) on Irritable Bowel Syndrome with Diarrhea: A Multicenter Randomized Double-Blind Placebo-Controlled Clinical Trial.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) decoction Chang'an I Recipe ( I ) in the treatment of irritable bowel syndrome with diarrhea (IBS-D). METHOD: A multicenter, randomized, double-blind, placebo-controlled clinical trial was designed. Based on the order of inclusion, the IBS-D patients were randomly assigned to the treatment group or the placebo control group, administrated with Chang'an I Recipe or placebo, 150 mL/bag, 3 times daily, for 8 weeks. The primary indices of efficacy included the effective rates of IBS symptom severity score (IBS-SSS) and the differences in adequate relief (AR) responder; the secondary indexes of efficacy included the changes in scores of the IBS Quality of Life (IBS-QOL) and Hospital Anxiety and Depression (HAD) scales. The safety indices included adverse events and related laboratory tests. RESULTS: A total of 216 patients were included, with 109 in the treatment group and 107 in the control group, and finally 206 were included in the full analysis set (FAS), 191 were included in the per protocol set (PPS). In FAS, the total effective rate was 67.6% and 40.2% for the treatment and control groups, respectively, with 95% confidence interval (CI) for difference in the effective rates between the two groups of 14.4%-40.2%; while in PPS, the total effective rate was 71.3% and 41.2% for the treatment and control groups, respectively (95% CI 16.6%-43.4%). The consistent conclusions of FAS and PPS showed a better efficacy in the treatment group. Both FAS and PPS showed higher AR responder in the treatment group (FAS: 59.6% vs. 35.5%; PPS: 62.8% vs. 38.1%). As for IBS-QOL, the total score and scores in various dimensions of IBS-QOL were not significantly different between the two groups (P>0.05). Both anxiety and depression scales of HAD were not significantly different between the two groups (P>0.05). No adverse events or laboratory abnormalities were found to be obviously related to the tested drugs or clinically significant. CONCLUSION: Chang'an I Recipe was more effective than placebo in the treatment of IBS-D, with no obvious adverse reactions. (No.ChiCTR-TRC-09000328).

Prevalence, risk factors and treatment practices in diarrhoeal diseases in south India.

OBJECTIVES: This study was done to determine the risk factors, management practices and awareness about diarrhoea. METHODS: It was a cross sectional study done in a semi urban and rural areas of South Canara district of India in February 2013. A total of 167 households (575 study population) chosen systematic randomly were visited and one adult member in each house was interviewed. The houses were also inspected to assess the living conditions. RESULTS: Mean age of study population was 31.1 ± 20.2 years. The period prevalence of diarrhoea was 69 (12 %). Commonest associated symptoms in cases of diarrhoea were fever 30 (43.4 %) followed by abdominal cramps 29 (42 %). Nearly half of the cases with diarrhoea 34 (49.3 %) did not take any medications. Commonest treatment taken was allopathic medicines 26 (37.8 %) followed by home remedies 8 (22.9 %). Age ≤10 years (p < 0.001) was associated with risk of developing diarrhoea using binary logistic regression analysis. Among the 167 participants, awareness level about the disease was poor among 16 (9.6 %) and moderate among 149 (89.2 % participants). Awareness level was more among females (p = 0.001) and literate participants (p = 0.013). One hundred and sixteen (69.5 %) participants were not aware of any sign or symptom of dehydration other than loose stools. Majority of the participants 138 (82.6 %) preferred home remedies as the initial management of diarrhoea. Misconception about fluid restriction in diarrhoea was stated by 12(7.2 %) participants. CONCLUSION: Public education program on proper feeding and management practices is required to address the various issues identified and for containment of diarrhoea cases in future.

[Functional and motor gastrointestinal disorders]. / Trastornos funcionales y motores digestivos.

This article discusses the most interesting studies on functional and motor gastrointestinal disorders presented at Digestive Diseases Week (DDW), 2015. Researchers are still seeking biomarkers for irritable bowel syndrome and have presented new data. One study confirmed that the use of low-dose antidepressants has an antinociceptive effect without altering the psychological features of patients with functional dyspepsia. A contribution that could have immediate application is the use of transcutaneous electroacupuncture, which has demonstrated effectiveness in controlling nausea in patients with gastroparesis. New data have come to light on the importance of diet in irritable bowel syndrome, although the effectiveness of a low-FODMAP diet seems to be losing momentum with time. Multiple data were presented on the long-term efficacy of rifaximin therapy in patients with irritable bowel syndrome and diarrhoea. In addition, among other contributions, and more as a curiosity, a study evaluated the effect of histamine in the diet of patients with irritable bowel syndrome.

Inhibitory effect of TongXie-YaoFang formula on colonic contraction in rats.

AIM: To investigate the pharmacological effect of TongXie-YaoFang (TXYF) formula and its underlying mechanisms. METHODS: A neonatal maternal separation plus restraint stress (NMS + RS) model of diarrhea-predominant irritable bowel syndrome was developed by subjecting male Sprague-Dawley rats to daily maternal separation from postnatal days 2 to 21 plus restraint stress from days 50 to 59. Rats were randomly divided into two groups (NMS + RS and TXYF formula), and rats with no handling or separation were used as normal controls. Starting from postnatal day 60, rats were administered TXYF formula (9.84 g/100 g body weight) orally twice daily for 14 consecutive days, while the normal and NMS + RS groups were given distilled water. The distinctions of movement index (MI, area under the curve of contraction intensity/min, mg/min) and contraction frequency (CF, number of contractions/min, times/min) of isolated colonic longitudinal smooth muscle strips (CLSMs) in the three groups before and after treatment were observed with a Power Lab system. Different inhibitors were applied, and then 10(-4) mol/L acetylcholine chloride (Ach) was added to CLSMs to induce muscle contraction. RESULTS: Before treatment, the MI of CLSMs in the NMS + RS and TXYF formula groups was similar and both higher than that in the normal group (545.49 ± 73.66 mg/min vs 245.76 ± 34.44 mg/min and 551.09 ± 54.29 mg/min vs 245.76 ± 34.44 mg/min, P < 0.01, respectively). After treatment, the MI in the TXYF formula group was lower than that in the NMS + RS group (261.39 ± 38.59 mg/min vs 533.9 ± 61.63 mg/min, P < 0.01). In the same way, the CF of CLSMs in the NMS + RS and TXYF formula groups was similar and both higher than that in the normal group (3.42 ± 0.25 times/min and 3.31 ± 0.21 vs 1.1 ± 0.17 times/min, P < 0.01) before treatment. After treatment, the CF in the TXYF formula group was lower than that in the NMS + RS group (1.42 ± 0.87 times/min vs 3.11 ± 0.82 times/min, P < 0.01) and similar to that in the normal group (1.42 ± 0.87 times/min vs 1.09 ± 0.13 times/min). When 8-(N,N-diethylamino)octyl 3,4,5-trimethoxybenzoate hydrochloride and 4-aminopyridine were added to the bath and equilibrated for 30 min, respectively, and 10(-4) mol/L Ach was added to CLSMs to induce muscle contraction, MI of the CLSMs in the TXYF formula group was lower than that in the normal group (666 ± 36.32 mg/min vs 747.77 ± 49.47 mg/min, and 686.53 ± 39.17 mg/min vs 750.45 ± 29.39 mg/min; P < 0.01, respectively). The MI of CLSMs in the TXYF formula group was lower than that in the normal group after treatment with nifedipine (689.48 ± 30.84 mg/min vs 741.65 ± 32.41 mg/min; P < 0.05). CONCLUSION: TXYF formula inhibits colon contraction in rats. This may be related to activation of specific potassium channels and inhibition of extracellular calcium internal flow.

Factorial study of moxibustion in treatment of diarrhea-predominant irritable bowel syndrome.

AIM: To identify an appropriate therapeutic regimen for using aconite cake-separated moxibustion to treat diarrhea-predominant irritable bowel syndrome (D-IBS). METHODS: A factorial design was employed to examine the two factors of moxibustion frequency and number of cones. The two tested frequencies were three or six moxibustion sessions per week, and the two tested doses were one or two cones per treatment. A total of 166 D-IBS patients were randomly divided into four treatment groups, which included each combination of the examined frequencies and doses. The bilateral Tianshu acupoints (ST25) and the Qihai acupoint (RN6) were selected for aconite cake-separated moxibustion. Each patient received two courses of treatment, and each course had a duration of 2 wk. For each group, the scores on the Birmingham irritable bowel syndrome (IBS) symptom questionnaire, the IBS Quality of Life scale, the Self-Rating Depression Scale (SDS), the Self-Rating Anxiety Scale (SAS), the Hamilton Depression (HAMD) scale, and the Hamilton Anxiety (HAMA) scale were determined before treatment, after the first course of treatment, and after the second course of treatment. RESULTS: The symptom, quality of life, SDS, SAS, HAMD, and HAMA scores of the patients in all 4 aconite cake-separated moxibustion groups were significantly lower after the first and second courses of treatment than before treatment (P < 0.001 for all). The symptom, quality of life, SDS, SAS, HAMD, and HAMA scores of the patients in all four aconite cake-separated moxibustion groups were significantly lower after the second course of treatment than after the first course of treatment (P < 0.001 for all). Between-group comparisons after the second course of treatment revealed that the symptom scores for group 1 (1 cone, 3 treatments/wk) and group 3 (2 cones, 3 treatments/wk) were significantly lower than that for group 2 (1 cone, 6 treatments/wk) (5.55 ± 5.05 vs 10.45 ± 6.61, P < 0.001; 5.65 ± 4.00 vs 10.45 ± 6.61, P < 0.001). Regarding the two levels of the two examined factors for aconite cake-separated moxibustion, after the first course of treatment, the changes in HAMA scores were significantly different for the two tested moxibustion frequencies (P = 0.011), with greater changes for the "6 treatments/wk" groups than for the "3 treatments/wk" groups; in addition, there were interaction effects between the number of cones and moxibustion frequency (P = 0.028). After the second course of treatment, changes in symptom scores for the 2 tested moxibustion frequencies were significantly different (P = 0.002), with greater changes for the "3 treatments/wk" groups than for the "6 treatments/wk" groups. CONCLUSION: An aconite cake-separated moxibustion treatment regimen of 3 treatments/wk and 1 cone/treatment appears to produce better therapeutic effects for D-IBS compared with the other tested regimens.

Use of traditional medicines to cope with climate-sensitive diseases in a resource poor setting in Bangladesh.

BACKGROUND: This study aims to explore the use of traditional medicines to cope with climate sensitive diseases in areas vulnerable to climate change. We assessed the extent to which traditional or alternative medicines were used for the treatment of the climate sensitive diseases by villagers as part of their health-coping strategies. METHODS: The study deployed a mixed-method research design to know the health-coping strategies of the people in a resource-poor setting.A cross sectional study was conducted from September 2010 to March 2011 among 450 households selected randomly in the districts of Rajshahi and Khulna, Bangladesh. The elder males or females of each household were interviewed. For qualitative methods, twelve focus group discussions (six with females and six with males) and fifteen key informant interviews were conducted by the research team, using interview guidelines on the use of traditional medicine. RESULTS: Univariate analysis showed that the use of traditional medicines has increased among community members of all socio-economic and demographic backgrounds. Due to the increased incidence of disease and sickness respondents had to increase the use of their cultural means to cope with adverse health situations. CONCLUSIONS: A systematic collection of knowledge on the use of traditional medicines to cope with climate-sensitive diseases can help the adaptation of communities vulnerable to climate change. In addition it can be instrumental in creating a directory of traditional medicine components used for specific diseases and highlight the effectiveness and relevance of traditional medicines as health-coping strategies. This may be useful for policymakers, researchers, and development partners to adapt existing health care policy in resource-limited contexts. It may also encourage WHO, national and international institutions, such as pharmaceutical companies, to carry out research investigating the effectiveness of these traditional medicines and integrate them with modern medicine. Overall, it could increase the health coping capacity of people in a resource-poor setting and contribute to their adaptation capabilities.

Health-related quality of life during postoperative chemoradiotherapy with oral uracil-tegafur and leucovorin in rectal cancer patients.

BACKGROUND/AIMS: The objective of this study was to report on the quality of life of locally advanced rectal cancer patients that were treated with uracil-tegafur (UFT)/leucovorin (LV)-based concurrent chemoradiotherapy. METHODOLOGY: Twenty-five patients were enrolled into this prospective study. Radiotherapy (50.4Gy) was given with concurrent UFT (300mg/m2/day) and LV (30mg/day). Turkish versions of EORTC-QLQC30 and EORTC QLQCR38 were applied at the beginning (HRQoL-1) and at the end (HRQoL-2) of chemoradiotherapy. Paired samples t-test was used to compare the difference of means for each scale between HRQoL1 and HRQoL2 and p values <0.05 were considered statistically significant. RESULTS: Study compliance was 80.6%. From baseline to the end of chemoradiotherapy, the mean scores of dyspnea (p=0.006) diarrhea (p=0.005) and micturition (p=0.005) increased significantly. Chemotherapy side effects also increased at the end of therapy (p=0.07). Seventy-six percent (76%) of male patients replied to questions related to sexual problems and functions, whereas no female patients replied. CONCLUSIONS: Although, diarrhea and micturition are the major problems, quality of life scores indicate that concurrent oral fluoropyrimidine-based chemoradiotherapy is a feasible treatment.

[Study of stress, coping and psychosomatic health among baccalaureate nurses-to-be]. / Stressz, coping és a pszichoszomatikus egészség vizsgálata leendo diplomás ápolók körében.

UNLABELLED: Stress is a risk factor that may endanger our quality of life and health. Certain occupational groups are particularly concerned, such as health care workers. OBJECTIVE: The present study aimed to investigate the stress load and coping strategies of nurses as well as their psychosomatic health. METHOD: The questionnaire survey was performed at the University of Szeged. The sample consisted of 208 nursing students (136 part-time and 72 full-time students). The self-completed questionnaire included items of psychosomatic symptoms, coping strategies and stress load. RESULTS: Persons characterized by high level of stress and more frequent psychosomatic symptoms tended to use inadaptive ways of coping more often; whereas those with a relatively lower stress level and fewer symptoms were not characterized by a more frequent use of active ways of coping but instead a lack of the inadaptive coping strategies. CONCLUSIONS: The authors concluded that vulnerability of the would-be baccalaureate nurses in this sample was especially high because they even used less effectively the ways of coping that otherwise aimed at both problem solving and maintaining their own health.

Apolipoprotein E4 influences growth and cognitive responses to micronutrient supplementation in shantytown children from northeast Brazil.

OBJECTIVE: Apolipoprotein E4 may benefit children during early periods of life when the body is challenged by infection and nutritional decline. We examined whether apolipoprotein E4 affects intestinal barrier function, improving short-term growth and long-term cognitive outcomes in Brazilian shantytown children. METHODS: A total of 213 Brazilian shantytown children with below-median height-for-age z-scores (HAZ) received 200,000 IU of retinol (every four months), zinc (40 mg twice weekly), or both for one year, with half of each group receiving glutamine supplementation for 10 days. Height-for-age z-scores, weight-for-age z-scores, weight-for-height z-scores, and lactulose:mannitol ratios were assessed during the initial four months of treatment. An average of four years (range 1.4-6.6) later, the children underwent cognitive testing to evaluate non-verbal intelligence, coding, verbal fluency, verbal learning, and delayed verbal learning. Apolipoprotein E4 carriage was determined by PCR analysis for 144 children. RESULTS: Thirty-seven children were apolipoprotein E4(+), with an allele frequency of 13.9%. Significant associations were found for vitamin A and glutamine with intestinal barrier function. Apolipoprotein E4(+) children receiving glutamine presented significant positive Pearson correlations between the change in height-for-age z-scores over four months and delayed verbal learning, along with correlated changes over the same period in weight-for-age z-scores and weight-for-height z-scores associated with non-verbal intelligence quotients. There was a significant correlation between vitamin A supplementation of apolipoprotein E4(+) children and improved delta lactulose/mannitol. Apolipoprotein E4(-) children, regardless of intervention, exhibited negative Pearson correlations between the change in lactulose-to-mannitol ratio over four months and verbal learning and non-verbal intelligence. CONCLUSIONS: During development, apolipoprotein E4 may function concomitantly with gut-tropic nutrients to benefit immediate nutritional status, which can translate into better long-term cognitive outcomes.

Bodily remembering: memory, place, and understanding Latino folk illnesses among the Amuzgos Indians of Oaxaca, Mexico.

This paper takes the theoretical construct of popular nosology of Latino folk illnesses and combines it with Edward Casey's concept of bodily remembering in order to more fully describe the role of memory and place in the illness experiences of the Amuzgos Indians of Oaxaca, Mexico. I ethnographically describe, across time, the interrelated links among social events, physical symptoms, and illness narratives of Latino folk illness popular nosologies as they are contextualized in their unique, social topographies. This enlarged theoretical perspective implies a smallest unit of meaning that is ethnographically defined, but that will often encompass more than the individual sufferer and more than one illness. The research objective of this study was to understand Amuzgan illness experiences through the narratives of detailed case histories and ethnographic observations that were gathered during 18 months of qualitative research. The data show that Amuzgos experience Latino folk illnesses as bodily rememberings of illness events combined with negative interpersonal interactions. Healing these Latino folk illnesses implies curing bodies, households, social relationships, and living environments.

Yogic versus conventional treatment in diarrhea-predominant irritable bowel syndrome: a randomized control study.

This study was conducted to evaluate the comparative effect of yogic and conventional treatment in diarrhea-predominant irritable bowel syndrome (IBS) in a randomized control design. The patients were 22 males, aged 20-50 years, with confirmed diagnosis of diarrhea-predominant IBS. The conventional group (n = 12, 1 dropout) was given symptomatic treatment with loperamide 2-6 mg/day for 2 months, and the yogic intervention group (n = 9) consisted of a set of 12 asanas (yogic poses, i.e., Vajrasana, Shashankasana, Ushtrasana, Marjariasana, Padhastasana, Dhanurasana, Trikonasana in two variations, Pawanmuktasana, and Paschimottanasana) along with Surya Nadi pranayama (right-nostril breathing) two times a day for 2 months. All participants were tested at three regular intervals, at the start of study--0 month, 1 month, and 2 months of receiving the intervention--and were investigated for bowel symptoms, autonomic symptoms, autonomic reactivity (battery of five standard tests), surface electrogastrography, anxiety profile by Spielberger's Self Evaluation Questionnaire, which evaluated trait and state anxiety. Two months of both conventional and yogic intervention showed a significant decrease of bowel symptoms and state anxiety. This was accompanied by an increase in electrophysiologically recorded gastric activity in the conventional intervention group and enhanced parasympathetic reactivity, as measured by heart rate parameters, in yogic intervention group. The study indicates a beneficial effect of yogic intervention over conventional treatment in diarrhea-predominant IBS.

Perceptions of and management practices for Diarrhoeal Diseases by traditional healers in northeastern Nigeria.

In Nigeria, there is a paucity of data on the beliefs and practices of traditional healers concerning diarrhoeal diseases. This study was undertaken to provide baseline data for integrating activities of traditional healers into the national Control of Diarrhoeal Diseases (CDD) programme. Interviews of 14 traditional healers, drawn from two large ethnic groups in northeastern Nigeria, were conducted. All but one of them willingly discussed their beliefs and practices. Almost all traditional healers used herbs expecting that it would stop diarrhoea episode. Most traditional healers (n = 11) were, however, aware of the sugar-salt solution (SSS), and six of them had positive impression about it. Ten were willing to be further trained in the preparation/use of SSS, and five reported its past use. Some healers strongly believed that breast-feeding was an important cause of diarrhoea and that, in some cases, diarrhoea was only amenable to traditional treatment. The results of this study suggest that the traditional healers in the region may contribute to promoting the appropriate home management of diarrhoea. However, their perceptions and practices need to be upgraded to ensure success.

Understanding of hygiene behaviour and diarrhoea in two villages in Botswana.

This paper describes a study which took place in two villages in north-east district of Botswana from July 1990 through July 1991. Qualitative data collection methods were used including: observations, key-informant interviews, focus groups, and in-depth interviews. The data were used for understanding and interpreting the cultural belief systems regarding specific hygiene behaviours and diarrhoea, with emphasis on hand washing. Hand washing was said to occur for three main reasons: to remove contamination, for social reasons, and for comfort reasons. Sources of dirt on the hands included human blood and faeces. Many perceived causes of diarrhoea were identified, including pogwana (dehydration associated with sunken anterior fontanelle). Traditional concepts regarding the treatment and prevention of diarrhoea were also identified. It is suggested that beliefs surrounding hygiene behaviour and diarrhoea should be incorporated into health education programmes.

PIP: During July 1990 to July 1991, in northeastern Botswana, focus groups, observations, and interviews were conducted in two villages largely inhabited by people from the Tswana and Kalanga tribes. Researchers examined hygiene behaviors (especially hand washing) and attitudes towards infantile diarrhea in these villages. Villagers considered hand washing after defecation to be a modern idea. Hand washing was not always done, especially if one went into the bush to defecate. People considered it more important to wash hands before meals. Identified sources of contamination were one's own body (through scratching, touching oneself while urinating, blowing the nose, hands [especially the left hand], blood [especially menstrual blood], and adult feces), soil, weeds, chicken feces, laundry water, and sometimes dish-washing water, but not cow dung and mud. Hand washing after touching each source was not always done. The focus groups identified a list of words for diarrhea in Setswana and Kalanga so health workers could track diarrhea morbidity. Both languages had a word for diarrhea that characterized the condition as having more frequent stools than usual and being affected by general ill health. Pogwana referred to dehydration associated with sunken anterior fontanelle. Many mothers did not know the cause of diarrhea. Some perceived causes of diarrhea were worms in the brain or in the stomach, a bewitched child, malnutrition, teething, watermelons, contaminated water or food, or cold weather. Ways to prevent diarrhea identified by the traditional healer included not feeding the child dirty food, not storing cooked food overnight, not giving too many different foods each day, and keeping yards swept. Diarrhea treatment options were: take the child to the clinic right away; visit a faith or traditional healer; and treat the child at home with oral rehydration salts, a home-made sugar/salt solution, or a traditional herb tea. All mothers mentioned additional fluids. Traditional healers sometimes used enemas. These findings suggest that health education programs should incorporate the beliefs revolving around hygienic behavior and diarrhea.
