Severe Enteropathy From Mycophenolate Mofetil.

The adverse effects of mycophenolate mofetil on the colon are well known. However, isolated small intestinal involvement resulting in diarrhea and severe weight loss is infrequently reported in the literature. We present the case of a 45-year-old woman on mycophenolate mofetil following renal transplant, who presented with abdominal pain and weight loss. An esophagogastroduodenoscopy and colonoscopy with biopsies were normal. A small bowel capsule study revealed extensive enteropathy of jejunum and ileum that was confirmed on a push enteroscopy with biopsies. Her symptoms completely resolved after being switched to enteric-coated mycophenolic acid.

NO-donating aspirin inhibits both the expression and catalytic activity of inducible nitric oxide synthase in HT-29 human colon cancer cells.

Nitric oxide-releasing aspirin (NO-ASA) is emerging as a potentially important chemopreventive agent against colon cancer. We examined in HT-29 human colon adenocarcinoma cells the effect of NO-ASA on the inducible form of nitric oxide synthase (NOS2), an enzyme implicated in colon carcinogenesis. NO-ASA inhibited in a time- and concentration-dependent manner the expression of NOS2 up to 70% compared to control (IC50 for this effect = 46 microM). NO-ASA also decreased the corresponding steady-state mRNA levels and this reduction preceded the reduction of protein levels by at least 6 h. NO-ASA also reduced the enzymatic activity of NOS2, as determined by a direct enzyme assay (maximal reduction = 80%) and by determining the accumulation of NO in the culture medium (IC50 for this effect = 36 microM). These effects of NO-ASA on NOS2 were paralleled by inhibition in cell growth (IC50 = 8.5 microM). These findings indicate that NO-ASA profoundly inhibits both the expression and enzymatic activity of NOS2 and suggest that these effects may represent an important mechanism for the colon cancer chemopreventive effect of NO-ASA.

IVC filter perforation through the duodenum found after years of abdominal pain.

BACKGROUND: The number of IVC filter-related complications has increased with their growing utilization; however, IVC filter perforation of the duodenum is rare. It can manifest with nonspecific abdominal pain, gastrointestinal bleeding, cava-duodenal fistula, or small bowel obstruction. CASE REPORT: A 67-year-old female presented with several years of right upper quadrant abdominal pain which was exacerbated by movement and food intake. She had a history of hepatic steatosis, cholecystectomy, and multiple DVTs with inferior vena cava filter placement. Physical exam was unremarkable. Laboratory tests demonstrated elevated alkaline phosphatase and transaminases. Esophagogastroduodenoscopy revealed a thin metallic foreign body embedded in the duodenal wall and protruding into the duodenal lumen with surrounding erythema and edema, but no active hemorrhage. Further evaluation with non-contrast CT scan revealed that one of the prongs of her IVC filter had perforated through the vena cava wall into the adjacent duodenum. Exploratory laparotomy was required for removal of the IVC filter and repair of the vena cava and duodenum. Her post-operative course was uneventful. CONCLUSIONS: In patients with history of IVC filter placement with non-specific abdominal pain, a high clinical suspicion of IVC filter perforation of the duodenum should be raised, as diagnosis may be challenging. CT scan and EGD are valuable in the diagnosis. Excellent outcomes have been reported with open surgical filter removal. Low retrieval rates of IVC filters have led to increased complications; hence, early removal should be undertaken as clinically indicated.

Pharmacologic management of mesenteric occlusive disease.

Mesenteric vascular disease has been diagnosed increasingly over the past 25 years. This rise in incidence has been attributed to the advanced mean age of the population, an increasing number of critically ill patients and a greater clinical recognition of the condition. Although surgical revascularization and resection has long been the standard of treatment, medical management can also play an important adjunctive role. Early diagnosis before irreversible bowel damage, which may occur within 6-8 hours after the insult, is necessary to improve survival and reduce morbidity. Even in the presence of irreversible bowel ischemia, perioperative medical treatment may reduce disease progression, enabling more limited bowel resection. This article outlines the appropriate pharmacologic management of ischemic disorders of the intestine, with an emphasis on the pharmacologic treatments presently being used in clinical practice and those being studied in the laboratory.

Osteopathic manipulative medicine in the treatment of hypertension: an alternative, conventional approach.

The branch of medicine known as osteopathy was founded by Andrew Taylor Still in the mid to late 19th century. Osteopathy is a philosophy of medicine. Osteopathic physicians use techniques collectively referred to as osteopathic manipulative medicine (OMM). One of the most common diseases suffered by those residing in westernized nations is hypertension. Although osteopathic physicians are taught to incorporate OMM into the management of medical disorders, the usefulness of OMM in treating hypertension is less clear. This review reflects on the past 90 years of biomedical literature and attempts to address the utility of OMM used alone, or in combination with other treatments including antihypertensive medication, for the effective management of hypertension. Preliminary evidence may suggest a role for OMM in treating hypertension within the context of a multifaceted and long-lasting treatment regimen that may include traditional pharmacotherapeutics. To have universal acceptance, controlled and blinded outcome studies are needed to determine the effectiveness of OMM for the routine treatment of hypertension.
