A metastatic carcinoma of the small intestine is rare. Here, the case study of an 80-year-old lung carcinoma patient, with generalized peritonitis due to neoplastic perforation of the small intestine is reported. Pathological studies of a small intestinal mass revealed a metastatic anaplastic carcinoma arising from the lung. Patients with known lung carcinoma, who develop abdominal complaints, should be examined thoroughly. Although it is very difficult to diagnose and treat a metastatic carcinoma of the small intestine, in our judgment, with a greater awareness of this neoplasm, more cases may be diagnosed in the early stages, leading to improved rates of survival.

Intoxication of sheep and cattle by recently occurred in Uruguay and Argentina in association with severe drought. Although the disease was experimentally reproduced in sheep in the 1970s, there is limited information on clinical and pathologic findings of sheep experimentally intoxicated by this beetle. Here, we described the clinical, gross, and microscopic findings in 3 sheep orally dosed with (treatment group, TG) and in 2 control sheep (control group, CG) dosed with distilled water.

Enterohemorrhagic (EHEC) is a contagious foodborne pathogen that specifically colonizes the human large intestine, which is regulated by different environmental stimuli within the gut. Transcriptional regulation of EHEC virulence and infection has been extensively studied, while the posttranscriptional regulation of these processes by small RNAs (sRNAs) remains not fully understood. Here we present a virulence-regulating pathway in EHEC O157:H7, in which the sRNA EvrS binds to and destabilizes the mRNA of Z2269, a novel transcriptional regulator.

Roux-en-Y gastric bypass (RYGB) is a bariatric surgical procedure commonly performed in adults to treat severe obesity. While RYGB is generally safe, it occasionally leads to rare but significant complications, including intussusception, a form of bowel obstruction caused by the invagination of an intestine segment from the proximal to the adjacent distal portion. We report a case of intussusception in a 74-year-old female patient who underwent RYGB 12 years prior.

Background/aims: Digestive disorders of gut-brain interaction (DGBI) are very common, predominant in females, and usually associated with intestinal barrier dysfunction, dysbiosis, and stress. We previously found that females have increased susceptibility to intestinal barrier dysfunction in response to acute stress. However, whether this is associated with changes in the small bowel microbiota remains unknown.
