This study determines the risk factors associated with suicide rates and the investigation of time trends in the deprived region of Epirus, north-west Greece, which is considered to be one of the least developed prefectures of the EU. Data selected demonstrated: (1) a mean age-standardized suicide rate per year of 4.00/100,000 for males, 1.29/100,000 for females and 2.65/100,000 for the total population; (2) a significant rising trend of male suicides in the 35-44 and 65-74 age groups; (3) a low female suicide rate in < 35 years age group and a relatively stable rate in the other age groups; (4) a significantly higher suicide rate in men than in women from both urban and rural areas and in older men from rural areas; (5) higher rates of suicide among widowed men and unmarried women; (6) the use of predominantly violent suicide methods, especially self-shooting, hanging and drowning; (7) a significant peak in the total suicide rate in the spring and summer months and a decreased rate in September; and (8) three out of four of the suicide victims had consumed alcohol and/or other drugs before the act. Data reported here shows some remarkable trends compared to previous reports on suicide in Greece and other countries, probably due to cultural and life style characteristics of the study population.

As there are, by definition, no biological parameters for diagnostic discretion in IBS, symptoms constitute a reliable basis for classification and diagnosis. Several acknowledged criteria such as "Manning criteria" followed by the "Kruis criteria" and the "Rome criteria (I-III), " have been used in order to establish diagnosis.IBS has been considered a common functional disorder implying a disorder without a discernible pathophysiological mechanism, thus a nonorganic disorder. 2,3 Traditionally, IBS has been viewed upon as a disorder where altered GI motility, visceral hypersensitivity, dysregulation of brain-gut axis, altered bowel motility, neurotransmitter imbalances and psychosocial factors are the most important pathophysiological pISSN 1598-9100 • eISSN 2288-1956 https://doi.Background/Aims: Irritable bowel syndrome (IBS) is a common disease often considered as a functional intestinal disorder. Inflammation in IBS is a quite intriguing theory. The aim of this study was to investigate tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 expression in inflammatory bowel disease (IBD) patients, IBS patients and normal controls. Methods: IBS and IBD patients along with normal controls were recruited in the study. In all groups, 2 pinch biopsies were taken at each of 3 anatomical sites (terminal ileum, cecum, and rectum). IBS patients were also subcategorized according to the syndrome clinical manifestations. Two monoclonal antibodies (mAb), TNF-α mAb and IL-6 mAb, and one polyclonal antibody IL-1β mAb were applied for immunohistochemical analysis. Results: In IBD patients intensity of TNF-α and IL-1β were lower than in IBS patients or controls, while IL-6 was significantly increased comparing to the aforementioned groups. In IBS patients TNF-α was increased comparing to IBD patients or controls, while IL-6 and IL-1β were similar to controls. In IBS subgroups, TNF-α was lower in diarrhea predominant IBS patients and higher constipation predominant IBS patients. Differences among IBS subgroups regarding IL-6 and IL-1β were nonsignificant. Conclusions: IL-6 seems to be the most important proinflammatory cytokine in IBD patients, while TNF-α could play a more significant role in IBS pathogenesis. (Intest Res 2020;18:115-120 )
