Peripheral T-cell lymphoma of the eyelid

Upon diagnosis of a chalazion, antibiotic eye drops and ointments as well as steroid eye drops were administered. However, the condition worsened rapidly and swelling of the lower eyelid became remarkable. An excisional biopsy revealed that the palpebral lesion was diagnosed as recurrence of PTCL. Electron irradiation was applied as a radical treatment, and the prognosis was satisfactory without recurrence at 10 months after the last irradiation.Conclusions: Although lymphoma isolated to the ocular adnexa is rare, it should always be included in the differential diagnosis of any patient presenting with progressive swelling of the eyelid or ocular region.Keywords: peripheral T-cell lymphoma, chalazion, eyeli

Impact of cardiac support device combined with slow-release prostacyclin agonist in a canine ischemic cardiomyopathy model

BackgroundThe cardiac support device supports the heart and mechanically reduces left ventricular (LV) diastolic wall stress. Although it has been shown to halt LV remodeling in dilated cardiomyopathy, its therapeutic efficacy is limited by its lack of biological effects. In contrast, the slow-release synthetic prostacyclin agonist ONO-1301 enhances reversal of LV remodeling through biological mechanisms such as angiogenesis and attenuation of fibrosis. We therefore hypothesized that ONO-1301 plus a cardiac support device might be beneficial for the treatment of ischemic cardiomyopathy.MethodsTwenty-four dogs with induced anterior wall infarction were assigned randomly to 1 of 4 groups at 1 week postinfarction as follows: cardiac support device alone, cardiac support device plus ONO-1301 (hybrid therapy), ONO-1301 alone, or sham control.ResultsAt 8 weeks post-infarction, LV wall stress was reduced significantly in the hybrid therapy group compared with the other groups. Myocardial blood flow, measured by positron emission tomography, and vascular density were significantly higher in the hybrid therapy group compared with the cardiac support device alone and sham groups. The hybrid therapy group also showed the least interstitial fibrosis, the greatest recovery of LV systolic and diastolic functions, assessed by multidetector computed tomography and cardiac catheterization, and the lowest plasma N-terminal pro-B-type natriuretic peptide levels (P < .05).ConclusionsThe combination of a cardiac support device and the prostacyclin agonist ONO-1301 elicited a greater reversal of LV remodeling than either treatment alone, suggesting the potential of this hybrid therapy for the clinical treatment of ischemia-induced heart failure
