Transient pulmonary and gastric bleeding after iopamidol administration in a patient with marginal zone lymphoma: a case report.

BACKGROUND: Iopamidol is a non-ionic, water-soluble iodine contrast agent that is considered safe for intravenous or intra-arterial administration and is widely used both in the general population and in patients undergoing oncological treatment. While adverse reactions to iopamidol have been documented, to date, no pulmonary and gastric hemorrhages induced by iopamidol have been reported in oncology patients. We report the first case of this complication. CASE PRESENTATION: We report the case of a 60-year-old woman with marginal zone lymphoma who was receiving antineoplastic therapy. As part of the investigation for the condition, she underwent chest enhancement CT with iopamidol. Shortly thereafter(within five minutes), she experienced hemoptysis and hematemesis. She was intubated and admitted to the intensive care unit. Pre- and post-contrast images demonstrated the course of the hemorrhage. Flexible bronchoscopy and gastroscopy on the following day showed no active bleeding, and the patient recovered completely after antiallergy treatment. We speculate that contrast-induced hypersensitivity was the most likely cause of the transient pulmonary and gastric bleeding. CONCLUSION: Although rare, the complications of iopamidol, which may cause allergic reactions in the lungs and stomach, should be considered.

Vibrio parahaemolyticus infection caused by market sewage: A case report and literature review.

Vibrio parahaemolyticus is distributed worldwide in seafood such as fish, shrimp, and shellfish and is a major cause of seafood-borne diarrhoeal disease. Previous studies have reported infections contacting with contaminated seafood seawater. So far, 11 cases reported of skin and soft tissue infections (SSTIs) caused by V. parahaemolyticus, which 5 patients died and 6 survived. We found that transmission through contact with contaminated water also causes infection. We report a 46-year-old male contracted V. parahaemolyticus after being splashed with market sewage. His condition deteriorated rapidly and he died eventually, suggesting that more atypical modes of V. parahaemolyticus transmission may be possible in the future. Literature review revealed that SSTIs due to V. parahaemolyticus are rare, so, detailed questioning of the patient's exposure history can help with empirical drug administration early. Patients with immunodeficiency disease and progressive blistering need mandatory debridement urgently. If fascial necrosis is found during debridement, early amputation may save the patient's life.
