Amyloid mesenteric angiopathy is difficult to diagnose as gastrointestinal (GI) signs are nonspecific and radiological studies rarely identify amyloid deposits with certainty. The objective of this study was to highlight the pathological findings of amyloid mesenteric angiopathy in cases of senile systemic amyloidosis. Literature review, author's research data, and practice experience were used. Systemic amyloidosis should be considered in the differential diagnoses when evaluating nonspecific and unexplained GI in patient population aged> 55 years to decrease the morbidity and fatal outcomes...

Adipose cells have traditionally been viewed as a simple, passive energy storage depot for triglycerides. However, in recent years it has become clear that adipose cells are highly physiologically active and have a multitude of endocrine, metabolic, haematological and immune functions. Changes in the number or size of adipose cells may be directly implicated in disease (for example, in the metabolic syndrome), but may also be linked to other pathological processes such as inflammation, malignant infiltration or infarction...

BACKGROUND: Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the role of surgery in metastatic disease of the thyroid. Isolated thyroidectomy has been proposed as a local disease control option to palliate and prevent the potential morbidity of tumor extension related to the airway...

BACKGROUND: The technical feasibility and oncological safety of laparoscopic surgery for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm has not been adequately studied. Therefore, we performed this retrospective study to investigate the clinical outcomes of gastric GIST patients treated with laparoscopic surgery compared with those who underwent open surgery. METHODS: We retrospectively evaluated the outcomes of 48 consecutive patients who underwent gastric resection for gastric GISTs larger than 5 cm...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, is now having increasing therapeutic role as well. We provide a review of the application of EUS in the diagnostic and therapeutic aspects of liver disease...

Crohn's disease (CD) is a chronic inflammatory disease, in most patients involving the small and large bowel. In recent years, with the use of small bowel video capsule endoscopy (SBCE), it has become clear that in 50% or more of adults with established CD there is not only distal but also proximal small bowel involvement that suggests poor prognosis. A great deal of effort has been put into early diagnosis and stratification of patients into low versus high risk, thus directing treatment from step-up, or accelerated step-up, to top-down therapies...

BACKGROUND: Intestinal ligation is the cornerstone for damage control in abdominal emergency, yet it may lead to bowel ischemia. Although intestinal ligation avoids further peritoneal cavity pollution, it may lead to an increased pressure within the bowel segments and rapid bacterial translocation. In this study, we showed that severed intestine could be readily reconnected by using silicon tubes and be secured by using rubber bands in a canine model. METHODS: Adult Beagle dogs, subject to multiple intestinal transections and hemorrhagic shock by exsanguination, randomly received conventional ligation vs...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Intestinal obstruction is a common complication in patients with advanced gastrointestinal malignancies. In the last two decades, endoscopic placement of duodenal stents has become a mainstay of palliative treatment in patients with unresectable obstructive duodenal pathology. Self-expandable metal stents have been reported to have excellent success rates, besides dramatically improve the patient's quality of life by reinstating the oral feeding ability. Re-intervention rates remain high, commonly as a consequence of tumour ingrowth resulting stent occlusion...

The enteric nervous system (ENS) controls the function of the gastrointestinal tract and has been implicated in various diseases, including Parkinson's disease (PD). PD is a neurodegenerative disease with Lewy bodies (LBs) and Lewy neurites (LNs) as the main pathological features. In addition to the typical motor symptoms in PD, attention has been drawn to non-motor symptoms, such as constipation, implying dysfunction of the ENS. In the present study, we characterized the age-dependent morphological alterations and aggregation of α-synuclein (α-syn), the primary protein component in LBs and LNs, in the ENS in an α-syn transgenic mouse model...

A four-year-old female was admitted to a university-based children's hospital with a newly-diagnosed posterior fossa tumor. She was started on famotidine and high-dose dexamethasone and underwent gross total resection of a medulloblastoma. She was continued on dexamethasone and famotidine. She exhibited postoperative posterior fossa syndrome and was started on enteral feeds via the nasoduodenal tube. She had small gastrointestinal bleeds on postoperative days eight, 11, and 18, and was found to have a well-circumscribed posterior duodenal ulcer...

Objective The long-term use of proton pump inhibitors (PPIs) may induce adverse events in many organs, including the stomach. The chronic use of PPIs has been associated with the growth of fundic gland polyps (FGPs) and of gastric black spots. This study assessed the incidence of gastric lesions with cobblestone-like appearance in PPI users. Methods The clinical characteristics and endoscopic findings of patients who underwent upper gastrointestinal endoscopy after using PPIs for at least six months were analyzed...

Mutations in one of the five genes encoding the succinate dehydrogenase (SDHx) or mitochondrial complex II cause the corresponding family syndromes characterized by the occurrence of pheochromocytomas (PHEO) and paragangliomas (PGL). Recently, other solid growths, such as gastrointestinal stromal tumors (GISTs), renal cell carcinomas (RCCs) and pituitary adenomas (PAs) have been associated with these syndromes. In the absence of prospective studies assessing their frequency, at present, their occurrence seems too infrequent to suggest systematic screening for SDHx mutation carriers...

OBJECTIVE: Alpha-synuclein (AS) accumulation identified by immunohistochemistry (IHC) of gastrointestinal (GI) tract biopsies is considered as a potential pathologic biomarker for Parkinson's disease (PD). We compared AS IHC findings in biopsy specimens and surgically resected full-depth specimens to examine the reliability of GI tract biopsies. METHODS: We included patients with PD who had undergone operation of the GI tract for treatment of tumors. Controls were matched with age at operation, gender, and surgical resection site...

The gastrointestinal tract serves as a fast-renewing model for unraveling the multifaceted molecular mechanisms underlying remarkably rapid cell renewal, which is exclusively fueled by a small number of long-lived stem cells and their progeny. Stem cell activity is the best-characterized aspect of mucosal homeostasis in mitotically active tissues, and the dysregulation of regenerative capacity is a hallmark of epithelial immune defects. This dysregulation is frequently associated with pathologies ranging from chronic enteritis to malignancies in humans...

One of the limitations for ranking foods and meals for healthiness on the basis of the glycaemic index (GI) is that the GI is subject to manipulation by addition of fat. Postprandial lipemia, defined as a rise in circulating triglyceride containing lipoproteins following consumption of a meal, has been recognised as a risk factor for the development of cardiovascular disease and other chronic diseases. Many non-modifiable factors (pathological conditions, genetic background, age, sex and menopausal status) and life-style factors (physical activity, smoking, alcohol and medication use, dietary choices) may modulate postprandial lipemia...

IL-17A is a cytokine which is produced by several immune and non-immune cells. The cytokine plays dual roles from protection from microbes and protection from pro-inflammatory based diseases to induction of the pro-inflammatory based diseases. The main mechanisms which lead to the controversial roles of IL-17A are yet to be clarified. Gut microbiota (GM) are the resident probiotic bacteria in the gastrointestinal tracts which have been introduced as a plausible regulator of IL-17A production and functions. This review article describes the recent information regarding the roles played by GM in determination of IL-17A functions outcome...

Multiple theories exist regarding the origin of bovine spongiform encephalopathy (BSE). An early and prominent theory proposed that BSE was the result of the adaptation of sheep scrapie to cattle. The reports to date indicate that the distribution of the pathological prion protein (PrPSc) in experimental bovine scrapie is largely restricted to the central nervous system (CNS). Here, we describe pathological findings in a calf intracerebrally inoculated with a Spanish classical scrapie isolate. While clinical disease was observed 30 months after inoculation and PrPSc was detected in the CNS, the corresponding phenotype differed from that of BSE...

Current studies of human gut microbiome usually do not consider the special functional role of transient microbiota, although some of its members remain in the host for a long time and produce broad spectrum of biologically active substances. Getting into the gastrointestinal tract (GIT) with food, water and probiotic preparations, two representatives of Bacilli class, genera Bacillus and Lactobacillus, colonize epithelium blurring the boundaries between resident and transient microbiota. Despite their minor proportion in the microbiome composition, these bacteria can significantly affect both the intestinal microbiota and the entire body thanks to a wide range of secreted compounds...

In spite of the global decline in its incidence and mortality, gastric carcinoma still remains a major cause of death due to cancer. Early detection of gastric carcinoma is expected to reduce mortality rates. The applications of measuring of pepsinogen I and pepsinogen II are useful in screening of gastric carcinoma. This cross sectional comparative study was done to find out the correlation of histopathological pattern of gastric carcinoma with serum pepsinogen I & II ratio in the Department of Pathology, Sylhet MAG Osmani Medical College, Sylhet, Bangladesh from January 2010 to December 2010...
