There has been much debate about how best to describe the relatively common occurrence of Brunner’s gland proliferation. In 1934, Feyrter classified the proliferation of Brunner’s glands into three categories: diffuse hyperplasia, circumscribed hyperplasia and glandular adenoma. More recently, it has been suggested that what Feyrter called the glandular adenoma is better described as a Brunner’s gland hamartoma. Supporting evidence includes the lack of encapsulation, the absence of dysplasia and the admixture of tissues including ducts, acini, smooth muscle, adipose tissue, lymphoid tissue and smooth sheets of Brunner’s glands, all contained within the pathological structure. As early as 1941, Robertsen argued that the similar histology of these three groups suggested that each might be induced by the same pathological process. It seems reasonable, therefore, that Brunner’s gland hyperplasia and the Brunner’s gland hamartoma are different but related manifestations of a common etiology.

He was taken to the operating room and was found to have a 3 cm, ulcerated, submucosal lesion just beyond the ampulla of Vater. He subsequently underwent a segmental resection of the third portion of the duodenum, with end-to-side duodenoduodenostomy. Surgical pathology revealed that the tumour was a Brunner’s gland hamartoma arising from the submucosal layer of the third portion of the duodenum (Figure 4). Two months after surgical resection, the patient was seen during follow-up, at which time, his hemoglobin concentration was normal, at 152 g/L, suggesting that this lesion was the source of his previous iron-defi-ciency anemia.

With the use of a radial 7.5 mHz echoendoscope (Olympus America, USA), the patient was noted to have a 2.7^4.0 cm hyperechoic, submucosal tumour in the third portion of the duodenum (Figures 3). The lesion had cystic components. It was located distal to the major papilla, and there was no evidence of periampullary, biliary or pancreatic invasion. A malignancy was suspected, especially a gastrointestinal stromal tumour, although a benign lesion such as a lipoma with cystic components could not be discounted. Consequently, fine needle aspiration was performed using a linear array 7.5 mHz echoendoscope (Pentax America, USA) to clarify the lesion further. The fine needle aspiration did not show malignant cells. However, because of continued bleeding, the patient was referred for surgical resection.

The colonoscopy revealed moderate sigmoid diverticulo-sis, three small colonic polyps and prominent internal hemorrhoids. These findings were not thought to explain his microcytic anemia or melena. Panendoscopy revealed a 3.5 cm, ulcerated, submucosal mass in the third portion of the duodenum, just beyond the ampulla of Vater (Figure 1).

A 45-year-old white man was admitted to hospital with weakness, lightheadedness and fatigue. He had been asymptomatic until two days before admission, when he began to experience melena. Upon admission to hospital, his hemoglobin concentration was noted to be low, at 61 g/L, with a mean corpuscular volume of 72.9 fL (normal range 85 to 95 fL) and a ferritin concentration of 1.0 pg/L. A nasogastric lavage was negative, and results of his other laboratory tests, including those for electrolytes and liver function, were unremarkable. He had no significant medical, surgical or family history, and he denied the use of any prescription or over-the-counter medications. He was not a smoker, but he did drink up to four beers per day. It’s time for you to stop spending more than your medications are worth: you have a chance to buy birth control online on very advantageous terms at the best online pharmacy of your choice, any time there is such a need.
He received 5 U of packed red blood cells over the next 24 h, and his hemoglobin concentration rose to 105 g/L. Because of his obvious iron deficiency, there was concern about his chronic gastrointestinal blood loss, and he subsequently underwent colonoscopy and esophagogastroduo-denoscopy.
Brunner’s gland hamartomas are infrequently occurring lesions, although they may represent as many as 5% of all benign duodenal tumours. Autopsy series report the finding of benign small intestinal tumours in 0.16% of cases. Presenting features may include upper gastrointestinal bleeding in 40% or, rarely, duodenal or gastric outlet obstruction; in as many as 25% of cases, they are an incidental finding. Patients typically present with symptoms in the fifth and sixth decades of life, and these lesions may be found in people of all races. Most Brunner’s gland hamartomas are smaller than 2 cm in diameter; larger tumours, as in the present case, are rare, although tumours as large as 10 cm have been reported. Although the natural history of this lesion is poorly defined, one recent case report noted a more than 20-year interval between the initial diagnosis and subsequent development of symptoms (upper gastrointestinal bleeding), suggesting an essentially benign clinical course.

Brunner’s glands are named after Brunner, the Renaissance pathologist credited with first describing these structures in the late 17 th century, after he noted glandular tissue in the proximal small intestine. These glands are located primarily in the deep mucosa and submucosa of the duodenum. They are most apparent proximally, and they decrease in number as the duodenum progresses distally. They function to protect the duodenal epithelium from the acid chyme that is delivered from the stomach; to do this they buffer the gastric efflux by secreting both an alkaline mucus as well as the paracrine hormone enterogastrone, which inhibits gastric acid secretion.

Probiotics have the potential to improve human health, and to prevent and treat a wide variety of diseases. Results from human clinical trials and scientific studies have confirmed the preventive and therapeutic effects of selected strains of microbes in viral and bacterial intestinal infections, and in positively influencing immunological parameters. However, several of these documented results need more rigorous research to be confirmed. Furthermore, it must be remembered that not all Lactobacillus or Bifidobacterium species are equal, and not all over-the-counter products contain the bacterial species listed on the label or, indeed, any viable bacteria at all. Thus, until major improvements occur in the regulation of labelling and quality assurance procedures for probiotic compounds, it is difficult to recommend which products to purchase. In addition, more adequately designed and properly executed clinical trials are necessary to carefully explore and characterize the therapeutic applications of probiotics.
Oral administration of probiotic compounds has been demonstrated to be well tolerated and proven to be safe in 143 human clinical trials occurring between 1961 and 1999. No adverse effects or events were reported in any of the 7526 subjects participating in these trials. However, rare cases of local or systemic infections, including septicemia and endocarditis due to Lactobacillus, have been reported. These infections have occurred in immunocompromised patients with aplasia, organ transplantation and human immunodeficiency virus infection. In most of these cases, the source of the infection was the commensal Lactobacillus flora, rather than an ingested bacteria supplement, suggesting that these bacteria can act as opportunistic pathogens. With regard to Saccharomyces infections, there have been few reports of fungemia due to Saccharomyces species, again, usually in immunocompromised patients receiving high enteral doses of Ultra-Levure (Biocodex, Montrouge, France) containing S boulardii (1.5 g/day). Although rare, these reports suggest that caution and further studies are necessary to assess the safety of probiotic bacteria for immunodeficient hosts.
The probiotic approach to the treatment of gastrointestinal disease remains controversial and will remain so until the mechanisms through which probiotic bacterial strains antagonize pathogenic organisms or exert other beneficial effects in the host are fully understood through well-planned scientific study. Furthermore, there are significant differences between probiotic bacterial genera and species. It is crucial that each strain be tested on its own or in products designed for a specific function. Much research is directed toward understanding the mechanisms of action of oral probiotics. The main areas being examined are receptor competition, whereby probiotics compete with microbial pathogens for a limited number of receptors present on the surface epithelium; probiotic release of antimicrobial compounds; probiotic-induced increased levels of mucin secretion, which acts to block pathogen binding to epithelial receptors; probiotic bacterial ‘priming’ of gut-associated lymphoid tissue; and immunomodulation of gut-associated lymphoid and epithelial tissue response. Probiotics are able to enhance the activity of the intestinal immune system through the stimulation of macrophage and natural killer cells, the proliferation of lymphocytes and the increase of secretory immunoglobulin A production, although the specificity of the secretory immunoglobulin A production was unknown. Selected strains of probiotics are able to alter mucosal and systemic immune function at many levels, including stimulating mucosal production of interleukin-10 and producing systemic T helper 2 reponses. However, it remains to be proven which, if any, of these mechanisms have a clinical benefit or how they alter the pathophysiology of gastrointestinal diseases. With regard to the pathophysiology of inflammatory bowel disease, one of the most widely accepted theories is that the inflammation results from a dysregulation of the immune system to normal gut flora. Thus, common probiotic species may contribute to chronic inflammation. However, in several animal models, not all gut microflora cause the same degree of inflammation. Indeed, there are several reports demonstrating that probiotic species tend to down-regulate pro-inflammatory cytokine release rather than stimulate secretion. Thus, while it is possible that some probiotic strains may contribute to chronic inflammation, some of the strains may actively suppress inflammation.
