A 79-year-old woman developed herpes zoster ophthalmicus (HZO) with a vesicular rash on the nasal root, which developed soon after intravenous acyclovir therapy. Although varicella zoster virus DNA was undetectable in the cerebrospinal fluid, she presented with ophthalmoplegia without optic nerve dysfunction 32 days after the onset of HZO. ⋯ Ophthalmoplegia did not immediately respond to these therapies but resolved 4 months later. We should be aware that ophthalmoplegia can occur, even after HZO and meningitis are completely treated.

We herein report a 56-year-old man with severe hypocalcemia during ruxolitinib therapy for myelofibrosis transitioning from JAK2 mutation-positive polycythemia vera. Blood transfusions were administered every one to two weeks for ruxolitinib-induced anemia. ⋯ Intact-PTH levels were relatively low compared to calcium levels. Severe hypocalcemia with ruxolitinib is rare and may be caused by a combination of factors, impaired vitamin D activation due to liver or renal insufficiency, accumulation of calcium-chelating agents from blood transfusions, and inadequate compensatory response to PTH.

A 17-year-old Japanese boy was admitted to our hospital with intermittent claudication. He belonged to a weightlifting team at a high school. ⋯ Intravascular ultrasonography revealed intimal thickening and thrombus formation He was diagnosed with thrombus occlusion of the right DPA due to intimal artery damage caused by lightweight weightlifting. DPA thrombosis may occur in young athletes who do not have atherosclerosis or vasculitis.
