Patients at the University of Oklahoma had an increased incidence of severe hypersensitivity infusion reactions when compared to the national average. Male patients and current smokers were found to be at increased risk for severe hypersensitivity infusion reactions in our study. Further investigation is warranted.

Sinusoidal obstruction syndrome, a complication occurring early after hematopoietic stem cell transplantation, is a concern for clinicians. There are no guidelines to direct clinicians on the optimal way to prevent and treat this disease. Newer data show that defibrotide is a promising drug both for prevention and treatment, although it is not yet FDA approved.

Eumycetoma is a chronic infection of the skin and subcutaneous tissue caused by filamentous fungi, which usually occurs in tropical or subtropical countries. We report a case of an immunocompromised patient presenting with presumed eumycetoma in the United States and his subsequent treatment with voriconazole. The use of voriconazole and liposomal amphotericin B halted the progression and allowed gradual resolution of the infection. The patient will require close monitoring and long-term therapy with voriconazole to obtain a clinical cure. Voriconazole and liposomal amphotericin B are potential initial treatment options, with long-term voriconazole maintenance therapy, for an Aspergillus-induced eumycetoma.

Ifosfamide is an alkylating agent used to treat different types of malignancies including lymphomas, sarcomas and germinal cell tumors. Symptoms of ifosfamide neurotoxicity can range from mild confusion, dizziness and hallucination to overt encephalopathy. Various treatment options like methylene blue, albumin infusion and rarely hemodialysis have been used to treat ifosfamide neurotoxicity. We hereby report a case of a patient with relapsed diffuse large B cell lymphoma who received methylene blue after experiencing acute renal failure and encephalopathy due to ifosfamide with no improvement. The prompt use of hemodialysis in this case has led to reversal of both renal failure and neurotoxicity.
