Malignant melanoma is the most common malignancy to metastasize to the gastrointestinal tract. In a retrospective computer-assisted data search of over 2500 patients with melanoma registered over the past 10 years, 110 patients have been identified to have premortem gastrointestinal metastatic disease (metastatic disease identified at least 6 months before death). The small intestine (35%), colon (14.5%), and stomach (7%) are the most common sites for metastases. Polypoid or ulcerating masses and intramucosal nodules are typical radiologic presentations for gastric and colonic lesions, while over 50% of the small bowel metastases are polypoid masses that many times act as leading points for intussusception. Endoscopic studies are helpful in the preoperative diagnosis of these lesions. In a subset of 38 patients with symptomatic small bowel metastatic disease, complete resections were performed in 26% of patients, with palliative bypasses being performed in 40%, despite the fact that over 50% of the patients had documented visceral metastasis in other body sites. The operative morbidity rate was 15% with no operative deaths. Ninety percent of patients gained relief of symptoms, and overall survival from the time of confirmed small bowel disease averaged 17.3 months, with a range of 6 months to 9 years. It would seem that patients with melanoma with gastrointestinal metastatic disease can benefit from aggressive radiologic and endoscopic procedures for diagnosis and staging. Only through surgical interventions for symptomatic gastrointestinal disease can the quality of life be improved and life expectancy be extended.

This is a retrospective case series consisting of five dogs diagnosed with schistosomiasis. The purpose of this article is to report the presence of naturally occurring canine schistosomiasis in Kansas and to provide clinical details regarding schistosomiasis. Medical records of dogs diagnosed with schistosomiasis from 2000 to 2009 were reviewed, and information extracted included signalment, history, clinical signs, diagnostic test results, treatment, and outcome. Affected dogs were primarily medium to large breed and young to middle aged. All dogs were considered outdoor dogs, with three having known access to surface water. Common clinical signs included gastrointestinal disease and signs associated with hypercalcemia. Fecal flotation was negative in all dogs in contrast to fecal saline sedimentation and fecal polymerase chain reaction, which were both positive in all dogs in which it was performed. All dogs treated specifically for schistosomiasis fully recovered. This article describes the first reported cases of canine schistosomiasis in the Midwest and the first reported case of intestinal intussusception secondary to schistosomiasis. Recognizing that canine schistosomiasis is present in Kansas and possibly other Midwestern states should prompt veterinarians to perform appropriate diagnostic investigation in suspect animals as the diagnosis is straight forward and relatively inexpensive.

Coeliac disease is the commonest immunological gastrointestinal disorder in the Western world. The symptoms of coeliac disease in adults are often non-specific, and a high index of suspicion may be required for timely diagnosis. We describe the case of a 46-year-old woman, with known dilated cardiomyopathy and pulmonary hypertension, who presented with non-specific abdominal symptoms, not initially attributed to gastrointestinal disease. Radiological investigations demonstrated transient small bowel intussusception without other abnormality, leading to the suggestion of coeliac disease as a cause, which was subsequently confirmed as the diagnosis.
