At present time, a number of questions regarding the pathophysiological characteristics and therapeutic approaches to treatment new coronavirus infection COVID-19 remain unresolved. In some cases, patients with may experience symptoms gastrointestinal tract disorder. According literature, SARS-CoV-2 can replicate in affect gut microbiota. The article aims review studies about possible relations...

Inflammatory bowel diseases (IBD) including most important forms; Crohn’s disease (CD) and ulcerative colitis (UC); are chronic diseases affecting the gastrointestinal tract with unclear etiology and pathology. The role of gut microbiota has recently been considered as major a factor, since altered microbiome or "dysbiosis" is a key player in the protracted course of inflammation in IBD. Howeve...

The association between nonsteroidal antiinflammatory drugs (NSAIDs) and upper gastrointestinal complications is well documented. However, epidemiologic data on the risk of clinically symptomatic but uncomplicated peptic ulcer are quite limited. The authors studied the association between prescription NSAIDs and the risk of symptomatic ulcer in a population-based cohort of 458,840 persons and 1...

The distinction between cyclooxygenase-2-selective inhibitors (CSIs) and nonsteroidal antiinflammatory drugs ultimately must be clinical and must be clinically and economically relevant. This distinction needs to be demonstrated in a substantial and clinically relevant difference in the respective rates of serious adverse reactions of the upper gastrointestinal tract. Event-driven, randomized, ...

The list of recently discovered gastrointestinal viruses is expanding rapidly. Whether these agents are actually involved in a disease such as diarrhea is the essential question, yet difficult to answer. In this review a summary of all viruses found in diarrhea is presented, together with the current knowledge about their connection to disease.

Henoch-Schönlein purpura (HSP) is one of the most common vasculitis of childhood. It is characterized by nonthrombocytopenic palpable purpura, arthritis, renal and gastrointestinal system (GIS) involvement. HSP is usually triggered by an antigenic stimulus including infectious agents, drugs, cold, insect bite or food. HSP is rarely triggered by Varicella zoster infection. We herein presented a ...

Clinical case A sixteen year old boy presented, three years before, gastrointestinal (abdominal pain, vomiting, diarrhea) and neurologic symptoms (headache, diplopia, ataxia, VI nerve paralysis), with fever, oral and genital aphtosis. Laboratory tests showed increased ESR, CRP). He carried B51HLA. Physical examination showed svere obesity, pseudomicropenis, rare pubic hair, pubertal stage G2P2....

The incidence of upper gastrointestinal (GI) complications of non-steroidal anti-inflammatory drugs remains the most common side effect. The objective of this study was to compare the incidence of upper gastrointestinal complications of Ibuprofen as non-selective non-steroidal anti-inflammatory drug (NSAID) to Celecoxib and Meloxicam as selective non-steroidal antiinflammatory drugs. This study...

Pancreatic exocrine adenocarcinoma is one of the most common malignancies associated with thromboembolism. The authors summarize the two abstracts (#368 and #273) presented at the 2012 ASCO Gastrointestinal Cancers Symposium which were focused on pancreatic thrombosis in ambulatory patients. In addition, they discuss the risk of thrombosis associated with malignancy, chemotherapy, and erythropo...

A series of five novel bis-1,5-disubstituted-1H-tetrazoles (bis-1,5-DS-1H-T) were quickly prepared by a catalyst-free Ugi-azide repetitive process from easily accessible starting materials in excellent yields, either at room temperature (88%-95%) or using mild MW-heating conditions (80%-91%). These molecules may have a wide range of applications, such as chelating agents, organocatalysts and lu...
