Vascular brain diseases are ranked the third as the cause of morbidity and mortality, in spite of the progress in diagnostic, therapeutic and preventive procedures. In the majority of cases of vascular brain diseases, it is ischemic brain disease, which is the final and the most severe stage of cerebral arteries atherosclerosis. Etiopathogenesis of atherosclerosis is not closer defined yet, but oxidative hypothesis is distinguished among the numerous theories. Within this theory, main place is attached to oxidative modification of LDL and Lp(a), together with numerous physiopathologic facts with the central role of reactive oxidative matters, where endothelial dysfunction is the main disorder responsible for the onset of numerous impairments, such as changes in coagulation-anticoagulation system. Considering these facts, it was established the hypothesis that in patients with IBD existed changes in hemostatic system, which were in positive correlation with the degree of cerebral atherosclerosis. The study comprised 36 patients with acute IBD and 28 patients with atherosclerotic encephalopathy. Control group was comprised of 30 patients with non-vascular diseases of similar characteristics. We investigated the correlation of the changes in hemostatic system (platelet aggregation, anti-thrombin III, D-dimer, protein C, factor VII, factor VIII, PAI-1) compared to the degree of cerebral atherosclerosis (ultrasonographically) and compared to the observed groups of patients. On the basis of all, the results of this study revealed significant increase of procoagulant factors concentration in patients with IBD, and similar changes were observed in patients with atherosclerotic encephalopathy, but less pronounced. All these changes in the total sample of patients, and particularly in patients with the pronounced cerebral atherosclerosis, are of primary and chronic character.

A 76-year old white married female had rapid onset dementia with myoclonus and was admitted to an HMO hospital where she was initially diagnosed as Alzheimer's disease. The physician- husband suggested that the condition might be due to the Pepto-Bismol which she had taken chronically to control her irritable bowel syndrome. An elevated serum bismuth level of 242 &mgr;g/L (normal is 5 &mgr;g/L) established bismuth toxicity as the cause of the dementia. With treatment the patient returned to a normal mental state. The possibility of bismuth encephalopathy needs to be considered in the differential diagnosis of possible Alzheimer's dementia.

Rifaximin, a non-resorbable broadband antibiotic, was approved in Germany 2 years ago for the treatment of traveller's diarrhoea caused by non-invasive enteropathogens. On account of the very good tolerance and the high efficacy against almost all enteropathogens this pharmaceutical, which has been available for 25 years, bears a high potential in many other indications which are currently under clinical investigations, including: symptomatic uncomplicated diverticular disease, Clostridium difficile-associated diarrhoea and pseudomembranous colitis, small bowel intestinal bacterial overgrowth, irritable bowel syndrome and hepathic encephalopathy. The present overview demonstrates potential indications in the field of gastroenterology and critically reviews the significance of rifiximin in the treatment of these diseases based on the latest clinica data.

We report two patients manifesting with involvement of central and peripheral nervous system with brain magnetic resonance imaging (MRI) changes and pathological features of neuropathy possibly due to harmful and chronic use of various nitroimidazole group of medications for recurrent diarrheal illness. Patient 1, a 21-year-old man with obsessive-compulsive disorder, impulsive behavior and harmful use of substance (tinidazole), had developed encephalopathy and biopsy-proven neuropathy with partial remission. The MRI of brain showed involvement of bilateral caudate, lentiform and dentate nuclei, and splenium, with contrast enhancement of the caudate and putaminal lesions and restricted diffusion of the splenial lesion. Patient 2 was a 50-year-old woman with irritable bowel syndrome and was on harmful use of tinidazole and metronidazole. She manifested with encephalopathy, ataxia, and neuropathy. Her MRI of brain revealed involvement of bilateral putamen, dentate nuclei and periventricular white matter with restricted diffusion. Sural nerve biopsy revealed evidence of vasculitic neuropathy. At follow-up, there was definite, though incomplete, recovery in both the patients. The MRI alterations improved completely in patient 2 and substantially in patient 1. Increasing awareness among the physicians may enable early recognition of potentially reversible neurotoxicity and avoid unwarranted prescription of such medications.

The scientific literature has demonstrated that probiotics have a broad spectrum of activity, although often the results are contradictory. This study provides a critical overview of the current meta-analyses that have evaluated the efficacy of probiotics in physiologic and pathological conditions, such as metabolic disease, antibiotic-associated and Clostridium difficile-associated diarrhea, IBS, constipation, IBD, chemotherapy-associated diarrhea, respiratory tract infection, ventilator-associated pneumonia, NAFLD, liver encephalopathy, periodontitis, depression, vaginosis, urinary tract infections, pancreatitis, incidence of ventilator-associated pneumonia, hospital infection and stay in ICU, mortality of post-trauma patients, necrotising enterocolitis in premature infants. Only for antibiotic- and Clostridium difficile-associated diarrhea, and respiratory tract infections the effects of probiotics are considered "evidence-based." Concerning other fields, meta-analyses lacks to define type and biologic effect of probiotic strains, as well as the outcome in a disease state. Therefore, the results presented should be a stimulus for further studies which will provide clinical recommendations.

Non celiac gluten sensitivity (NCGS) is a syndrome characterized by a cohort of symptoms related to the ingestion of gluten-containing food in subjects who are not affected by celiac disease (CD) or wheat allergy. The possibility of systemic manifestations in this condition has been suggested by some reports. In most cases they are characterized by vague symptoms such as 'foggy mind', headache, fatigue, joint and muscle pain, leg or arm numbness even if more specific complaints have been described. NCGS has an immune-related background. Indeed there is a strong evidence that a selective activation of innate immunity may be the trigger for NCGS inflammatory response. The most commonly autoimmune disorders associated to NCGS are Hashimoto thyroiditis, dermatitis herpetiformis, psoriasis and rheumatologic diseases. The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported; it could be a characteristic feature that could help the diagnosis and be simultaneously managed. A possible neurological involvement has been underlined by NCGS association with gluten ataxia, gluten neuropathy and gluten encephalopathy. NCGS patients may show even psychiatric diseases such as depression, anxiety and psychosis. Finally, a link with functional disorders (irritable bowel syndrome and fibromyalgia) is a topic under discussion. In conclusion, the novelty of this matter has generated an expansion of literature data with the unavoidable consequence that some reports are often based on low levels of evidence. Therefore, only studies performed on large samples with the inclusion of control groups will be able to clearly establish whether the large information from the literature regarding extra-intestinal NCGS manifestations could be supported by evidence-based agreements.

Irritable bowel syndrome (IBS) is often associated with other unexplained complaints like chronic fatigue syndrome (CFS), fibromyalgia and myalgic encephalopathy (ME). The pathogenesis of the relationship is unknown. Intestinal dysbiosis may be a common abnormality, but based on 1100 consecutive IBS patients examined over a nine years period, we hypothesize that the development of the disease, often from IBS to ME, actually manifests a "dysbiotic march". In analogy with "the atopic march" in allergic diseases, we suggest "a dysbiotic march" in IBS; initiated by extensive use of antibiotics during childhood, often before school age. Various abdominal complaints including IBS may develop soon thereafter, while systemic symptom like CFS, fibromyalgia and ME may appear years later.
