Review Case Reports
Refractory IgG4-related Pleural Disease with Chylothorax: A Case Report and Literature Review.
We herein report a rare case of a 66-year-old man with refractory chylothorax. Although he had been treated with moderate doses of prednisolone (PSL) on suspicion of pleuritis with Sjögren syndrome, the pleural effusion expanded after the reduction of PSL. ⋯ Combination therapy with high-dose PSL plus rituximab successfully decreased the pleural effusion. This is a very rare case of IgG4-related pleuritis with chylothorax and the first report of its successful treatment with rituximab.

Objective Despite reports on the effects of ankle-brachial index (ABI) improvement following endovascular therapy (EVT) on the limb prognosis, studies evaluating cardiovascular events are limited. We investigated whether or not ABI improvement 1 year following EVT was associated with cardiovascular events. Methods The I-PAD NAGANO registry is an observational multicenter cohort study that enrolled 337 patients with peripheral artery disease (PAD) who underwent EVT between August 2015 and July 2016. ⋯ Results The incidence of MACEs was significantly higher in the ΔABI <0.15 group than in the ΔABI ≥0.15 group (ΔABI <0.15 vs. ΔABI ≥0.15, 25.8% vs. 11.9%, log-rank p=0.036), as was the incidence of stroke (14.1% vs. 2.2%, log-rank p=0.016). A Cox regression analysis revealed that ΔABI ≥0.15 was significantly associated with fewer MACEs (hazard ratio 0.38, 95% confidence interval 0.17-0.83, p=0.016). Conclusion An increase in ABI ≥0.15 at 1 year following EVT was a predictor of reduced MACEs.

Case Reports
Successful Conservative Treatment of Cardiac Rupture Associated with Takotsubo Syndrome.
We herein report a 75-year-old woman who was diagnosed with Takotsubo syndrome (TTS) complicated by left ventricular outflow tract obstruction on admission. Treatment with beta-blocker and anticoagulant was started; however, her hemoglobin level decreased gradually, and computed tomography performed one week later revealed hemopericardium. ⋯ It is noteworthy that cardiac rupture may occur with TTS, especially in patients treated with prophylactic anticoagulation therapy for apical thrombus. Furthermore, conservative, careful observation is an alternative approach in patients with oozing-type cardiac rupture associated with TTS.
