[Effect of food allergen exculsion on symptoms and quality of life in irritable bowel syndrome]

Irritable bowel syndrome [IBS] is one of the most common gastrointestinal disorders characterized by abdominal pain or discomfort and altered bowel habits. Although IBS etiology is poorly understood, some psychological disturbances and food allergies have been proposed. This study was done to determine the effect of food allergen exculsion on symptoms and quality of life in IBS. In this descriptive and anolytical study was done on 100 IBS patients in Tabriz, Iran during 2011. Food allergies of specific origin and effects of non allergic regimens on quality of life, pain severity and disease symptoms were evaluted during one month period. Data were analyzed using SPSS-16, student's t-test, Chi-Square and Fisher's exact tests. Patients age were 31.5 +/- 7.2 between 15-43 years. Specific antibodies against allergic foods were detectable in 31 [31%] cases. Penaut showed to induce the highest food allergy in 5 [16.1%] patients. The median disease duration was 4.5 +/- 2.6 years in allergic patients while 3.5 +/- 2.9 in non allergic group with no significant difference. The changes is quality of life was significant in non allergic regimens after one month in allergic group [P<0.05] while disease symptoms such as mucus defecation and flatulence had no significant changes. This study showed that one month non allergic regimens reduce abdominal pain and improve quality of life in IBS patients

[Chemical quality of water entrance to dialysis machines and its comparison with AAMI and EPH standards in hospitals of Qom province, Qom, Iran]

The presence of certain chemical compounds in dialysis water which enter patients' bodies through haemodialysis can cause various problems such as acute poisoning, brain damage, osteoarthritis, Therefore, applying the standards for dialysis water is indispensible. This study was carried out to determine the chemical quality of water entrance to dialysis machines and its comparison with AAMI and EPH standards in the hospitals of Qom province. This is a descriptive-cross sectional study which was carried out on 45 samples of water entrance to dialysis machines in hospitals of Qom province. Since there were 3 hospitals in Qom having dialysis units, out of each one 15 samples were chosen as the samples of this study. The following machines were used for analysis of samples in the research: Atomic Absorption, DR4000 and Flame photometer. The gathered data were then analyzed by independent t-test [p<0.5]. The means of all measured compounds were statistically lower than standard levels and had a significant difference with standard levels. The elements and compounds such as Lead, Zinc, Potassium, Sodium, Sulphate, Nitrate, and Chloride in all the measured samples were below the standard levels, but elements such as Aluminum, Cadmium, and Fluoride were above the standard levels in 13, 6 and 9 percent of samples, respectively. The results of the study showed that in all cases the means of all the studied compounds were below the standard levels, indicating high quality dialysis water in the hospitals. However, the presence of high level of elements such as Aluminum, Cadmium, and Fluoride compared with the standard levels signifies that much should be done in examining dialysis water
