Abdominal migraine in adults: a review of pharmacotherapeutic options.

OBJECTIVE: To report the case of a 32-year-old woman with abdominal migraine and present a literature review to evaluate abdominal migraine in adults, with particular regard to effective treatment. CASE SUMMARY: A 32-year-old African American female presented with recurrent, severe abdominal pain. The patient had several previous admissions with similar symptoms and an extensive gastrointestinal workup in which findings were normal. Attacks of abdominal pain occurred despite treatment with analgesics and antiemetics. She had a family history of migraine headaches. A diagnosis of abdominal migraine was presumed and prophylactic therapy with topiramate 50 mg twice daily relieved the symptoms. DISCUSSION: Most published cases of adult abdominal migraine describe females who had a long history of abdominal pain refractory to conventional therapies. The majority of patients had a strong family history of migraine and reported similar episodic abdominal pain. Patients responded to prophylactic migraine therapies, including calcium channel blockers, ß-blockers, topiramate, and antihistamines; a few responded to abortive sumatriptan therapy. CONCLUSIONS: Abdominal migraine should be considered a possible source of incurable abdominal pain in adults when accompanied by a complete gastrointestinal workup with normal results. We recommend a trial of topiramate as prophylactic therapy if abdominal migraine is the likely source of the pain.

Retrospective Evaluation of Postoperative Adverse Drug Events in Patients Receiving Rivaroxaban After Major Orthopedic Surgery Compared with Standard Therapy in a Community Hospital.

STUDY OBJECTIVES: To evaluate the occurrence of bleeding and venous thromboembolic (VTE) events in patients receiving rivaroxaban, warfarin, or warfarin with the addition of enoxaparin during the immediate postoperative period following major orthopedic surgery. METHODS: Patients older than 18 years who received at least one dose of rivaroxaban the morning following surgery, adjusted dose warfarin, or adjusted dose warfarin with the addition of enoxaparin for VTE prophylaxis after major orthopedic surgery between October 1, 2011, and February 28, 2015, were included. Data collected from the electronic health record included patient demographics, renal function, inpatient aspirin, P2Y12 inhibitor and/or nonsteroidal antiinflammatory drug (NSAID) use, type of surgery, postoperative analgesia, and presence of VTE risk factors. Adjusted incidence rate ratio for bleeding or VTE events was estimated using modified Poisson regression with robust standard errors. Covariates included in a multivariable model were age, sex, aspirin use, P2Y12 inhibitor use, NSAID use, obesity, VTE risk factors, and creatinine clearance. RESULTS: There were 3246 patients who met study inclusion criteria. Overall, incidences of bleeding and VTE events were rare. Bleeding event incidence ranged from 0.4% in the warfarin and warfarin with the addition of enoxaparin groups to 1.2% in the rivaroxaban group (p=0.088). There were two major bleeding events and 18 minor bleeding events (including hemorrhagic wound complications). VTE event incidence ranged from 0.2% in the warfarin with the addition of enoxaparin group to 0.6% in the rivaroxaban group (p=0.230). Two deep vein thromboses and 10 pulmonary emboli occurred. With use of the multivariable model, the warfarin and warfarin with the addition of enoxaparin groups had significantly lower incidence rates of bleeding compared with rivaroxaban (incidence rate ratio [IRR] = 0.218, p=0.0120, and IRR = 0.242, p=0.021, respectively). PRINCIPAL CONCLUSIONS: We observed a small, yet significant, increase in rivaroxaban-related bleeding in the immediate postoperative period relative to warfarin or warfarin with the addition of enoxaparin for the prevention of VTE after major orthopedic surgery.

Gastrointestinal bleeding following intravenous ibandronate administration.

PURPOSE: Gastrointestinal (GI) adverse effects have been reported with oral bisphosphonate formulations and are the primary adverse effects influencing their tolerability. New intermittent formulations, including intravenous (IV) ibandronate, may increase compliance and decrease the rate of GI adverse effects. We describe a 67-year-old woman with a 2-day history of hematemesis and melena 1 week after administration of IV ibandronate. SUMMARY: The patient was initially stable but began to develop a small bowel obstruction for which a nasogastric (NG) tube was placed. During placement of the NG tube, the patient vomited and aspirated. Due to continued nausea and vomiting with the NG tube and shortness of breath, the patient was intubated and an orogastric tube was placed. Despite the use of a ventilator, the patient's blood pressure and oxygen saturation began to fall. Even with the use of mechanical ventilation and 3 pressors, her condition deteriorated, she was made DNR/DNI (do not resuscitate or intubate) and subsequently expired. The Naranjo adverse drug reaction score was 2, indicating a possible association between GI bleed and IV ibandronate. The exact mechanism of this is not known. CONCLUSION: Clinicians should be aware of this possible adverse effect and monitor high-risk patients for bleeding when administering IV bisphosphonates.
