Background and Objective: 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. Materials and Methods: 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. Results: 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. Conclusion: This study showed that one month non allergic regimens reduce abdominal pain and improve quality of life in IBS patients.

Background and Objective: With the increase in the spread of COVID-19, mental health consequences such as fear, anxiety, and depression have become prevalent. This study aimed to investigate the predictive role of fear of COVID-19 and quarantine fatigue on depression in congenital heart disease patients during the pandemic.
Methods: This descriptive-analytical study was conducted on 105 patients with congenital heart disease (6 men and 99 women) who were referred to Shahid Rajaee Hospitals and Tehran Heart Center during 2021-22. Data were collected using a depression scale, a fear scale for COVID-19, and a quarantine fatigue questionnaire.
Results: The results showed that 28.6% of patients with congenital heart disease experienced mild depression, while 7.6% had severe depression. Quarantine fatigue was found to be mild in 43.8% of patients. Additionally, fear of COVID-19 (r=0.195, P=0.001) and quarantine fatigue (r=0.617, P=0.001) were significantly correlated with depression in congenital heart patients.
Conclusion: Fear of COVID-19 is related to depression caused by coronavirus and quarantine fatigue in patients with congenital heart disease.
