We report on a case of a 26-year-old intravenous narcotic abuser with a primary cerebral mucormycotic abscess caused by Rhizopus oryzae. He was treated with a combination of intravenous and intraventricular amphotericin B and surgical drainage with a successful outcome. ⋯ Mucormycosis presenting in this way has been described previously but this is only the second such case to survive. Early diagnosis and treatment is essential for a favourable outcome in this condition.

Factor V inhibitors are uncommon, bleeding manifestations variable and recommendations for management are unclear. We present a patient with non-Hodgkins lymphoma who developed gastrointestinal bleeding and was found to have a Factor V inhibitor. ⋯ Resolution of bleeding was associated with a fall in the levels of the inhibitor and of platelet associated IgG. The patient had no further bleeding episodes nor evidence of progression of his lymphoma, but six months later died as a result of metastatic adenocarcinoma.

Randomized Controlled Trial Comparative Study Clinical Trial
Gastrointestinal blood loss from a new buffered aspirin (Ostoprin): measurement by radiochromium and Hemoquant techniques.
Occult gastrointestinal blood loss induced by a new buffered aspirin preparation (Ostoprin, 4.0 g per day) was compared with that from an enteric-coated aspirin (Ecotrin, 3.9 g per day) in 40 patients with osteoarthritis. Blood loss was measured by the radiochromium method and compared with the HemoQuant assay of fecal heme and heme-derived porphyrins. By radiochromium, mean daily blood loss during the first week of treatment with Ostoprin increased 1.6 ml above basal compared to 0.8 ml above basal with Ecotrin (p = 0.06). ⋯ Serum salicylate levels achieved with both preparations were almost identical and encompassed the therapeutic range. HemoQuant is sufficiently sensitive to detect low-level aspirin-induced bleeding. Ostoprin appears to be a safe alternative to Ecotrin and has similar bioavailability.

A 43-year-old Polynesian presented with fever, abnormal liver function tests, bilateral pulmonary infiltrates, and a progressive neutropenia and thrombocytopenia. Bone marrow examination showed extensive and striking hemophagocytosis which raised the diagnosis of malignant histiocytosis. Mycobacterium tuberculosis was subsequently cultured from both urine and bone marrow. Hemophagocytosis is now a recognised association of several infections and we draw attention to this finding, particularly as the confident exclusion of malignancy can be very difficult and management is obviously very different.
