Opsoclonus-myoclonus syndrome (OMS) is a rare paraneoplastic syndrome that occurs in 2%-3% of patients with neuroblastoma. The cause of this syndrome is believed to be immune mediated, but the exact mechanism still remains unclear. There is an urgent need to improve our current strategies for treating patients with OMS, as many patients have significant long-term neurologic deficits and behavior disorders with current treatment approaches. Therapies that have shown to improve symptoms in these patients have ranged from ACTH and corticosteroids, to intravenous gammaglobulin and plasmapheresis. We report our experience with Rituximab in a patient with neuroblastoma and OMS.
Blindness is the most serious injury to the eye following a midfacial fracture. The onset of blindness complicating the midfacial fracture may be immediate (with the trauma), delayed (hours to days), or postoperative. The incidence of postoperative blindness lies between 0.3 and 8.3%. There are multiple mechanisms responsible for blindness but the most common reason with about 66% is probably increased intraorbital pressure attributable to intraorbital hemorrhage. The management of surgical decompression of the orbit for acute blindness is essential when treatment of a midfacial fracture is intended. Acute orbital compartment syndrome can effectively be relieved by lateral canthotomy and cantholysis and administration of high doses of corticosteroids. Further possibilities of surgical decompression of the orbit are discussed in this case report with postoperative irreversible blindness after reduction of a malar fracture and rapidly performed surgical decompression.
This review examines ulcers and gastrointestinal bleeding with low-dose aspirin, focusing on randomized placebo-controlled trials. The single endoscopic trial assessing ulcers showed no significant difference in 12-week ulcer incidence: 6% of 381 given placebo vs. 7% of 387 given 81 mg enteric-coated aspirin. The relative risk of major gastrointestinal bleeding with low-dose aspirin in a meta-analysis of placebo-controlled trials of vascular protection was 2.07 (95% CI: 1.61-2.66). The absolute rate increase with aspirin above placebo was 0.12% per year (95% CI: 0.07-0.19%) with a number-needed-to-harm of 833 patients (95% CI: 526-1429). A meta-analysis of aspirin 50-1500 mg daily reported an odds ratio for any gastrointestinal bleeding of 1.68 (95% CI: 1.51-1.88) with an number-needed-to-harm at 1 year of 247. The relative risk of hospitalization for upper gastrointestinal bleeding with low-dose aspirin in a large Danish cohort study was 2.6 (95% CI: 2.2-2.9) with an absolute annual incidence of 0.6%. Factors that may increase the risk of gastrointestinal bleeding include prior history of ulcers or gastrointestinal bleeding, corticosteroid use, anticoagulant therapy and addition of a non-aspirin non-steroidal anti-inflammatory drug. When determining whether low-dose aspirin is appropriate for an individual patient, the cardiovascular benefit must be weighed against the potential for clinical events such as gastrointestinal bleeding.
