ABSTRACT
Adult intestinal toxemia botulism (ITB) is a rare illness that can be fatal if not recognized. ITB can occur when botulinum neurotoxin-producing clostridia colonize the intestine. Underlying intestinal abnormalities associated with dysbiosis are likely a prerequisite for colonization. Dysbiosis seems necessary for spore germination and neurotoxin production. Botulism neurotoxins are the most lethal poisons known and are classified into 7 serotypes: A through G. The clinical presentation consists of cranial nerve abnormalities and descending flaccid paralysis. Prompt recognition and treatment with botulism antitoxin and supportive measures is often successful, but delayed recognition can be fatal. In this study, we present a case of a 40-year-old woman with Crohn's disease who developed ITB. This is the first case in literature to report adult intestinal botulism from Clostridium botulinum producing toxin B and F in the same patient.
ABSTRACT
BACKGROUND: Stents have been placed through malignant pancreatic strictures, mainly to alleviate pain of presumed obstructive origin. Self-expanding metallic stents have major advantages over plastic stents when used for treatment of malignant biliary strictures. However, there are few reports of their use in patients with malignant pancreatic duct strictures, especially those with complications related to ductal obstruction. METHODS: Self-expanding metallic stents were placed in the pancreatic ducts of 3 patients with obstructive complications of pancreatic cancer: smoldering pancreatitis, a disrupted pancreatic duct with pseudocyst caused by open surgical biopsy, and a disrupted pancreatic duct with fistula and resultant liver abscess. All 3 patients had metallic stents placed concomitantly in the biliary tract; one had enteral stents placed as well. Clinical and pathology records and imaging studies were reviewed retrospectively. OBSERVATIONS: In all cases, there was resolution of the specific clinical problem and reasonable survival (1.5 years in one patient). CONCLUSIONS: The use of self-expanding metallic stents for treatment of certain obstructive complications of pancreatic tumors is feasible and effective.
