Pulmonary cryptococcosis in a ruxolitinib-treated patient with primary myelofibrosis.

We present the case of a 79-year-old man who showed multiple pulmonary nodules on chest computed tomography (CT) after being treated for 6 months with ruxolitinib, an inhibitor of Janus kinase (JAK) 1 and 2, to treat primary myelofibrosis. We examined the lesions by bronchoscopy, and the biopsy specimen revealed fungus bodies of with granulomatous inflammation. As a result, the patient was diagnosed with pulmonary cryptococcosis.

Long-Term Vitamin E-Deficient Mice Exhibit Cognitive Dysfunction via Elevation of Brain Oxidation.

Vitamin E inhibits oxidative processes in living tissues. We produced vitamin E-deficient mice by feeding them a vitamin E-deficient diet to verify the influence of chronic vitamin E deficiency on cognitive function. We measured cognitive function over a 5-d period using the Morris water maze task, as well as antioxidant enzyme activity and lipid peroxidation in discrete brain regions, and total serum cholesterol content.
