Background: The results of recent trials have brought some confusion to the treatment strategy for renal artery stenosis (RAS). To evaluate the applicability of percutaneous transluminal renal angioplasty (PTRA) for RAS, we extracted the factors that may affect the effectiveness of PTRA from cases experienced at a hypertension center. Methods and Results: We retrospectively assessed the blood pressure (BP) lowering effects and renoprotective effects in 50 consecutive patients that had hemodynamically significant RAS and had undergone PTRA and stenting during 2001-2005...

OBJECTIVE: Antihistamines often have sedative side effects. This was the first study to measure regional cerebral glucose (energy) consumption and hemodynamic responses in young adults during cognitive tests after antihistamine administration. METHODS: In this double-blind, placebo-controlled, three-way crossover study, 18 healthy young Japanese men received single doses of levocetirizine 5 mg and diphenhydramine 50 mg at intervals of at least six days. Subjective feeling, task performances, and brain activity were evaluated during three cognitive tests (word fluency, two-back, and Stroop)...

OBJECTIVE: Metformin is an antidiabetic drug that is widely used to treat patients with diabetes mellitus. Recent studies have reported that treatment with metformin not only improved blood glucose levels but also reduced blood pressure. However, it remains unclear how metformin reduces blood pressure. We hypothesized that metformin affects sodium reabsorption in the kidneys. METHODS: Urinary sodium excretion and expression of renal sodium transporters were examined in 8-week-old male C57BL/6 mice with acute and chronic treatment of metformin...

A 71-year-old man, who had received long-term oxygen therapy for respiratory failure caused by chronic obstructive pulmonary disease, had an enlarged mediastinal lymph node for one year. As his lung function was poor, we tried performing endobronchial ultrasound-guided transbronchial needle aspiration under non-invasive positive pressure ventilation for diagnosis but could not obtain sufficient specimens. Later, we performed an endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA) using a transesophageal approach...

Objectives: Takayasu arteritis (TA) and GCA are large-vessel vasculitides characterized by vascular remodelling involving endothelial cells (ECs) and vascular smooth muscle cells. Mammalian target of rapamycin (mTOR) pathway has been involved in vascular remodelling. We hypothesized that the mTOR pathway was involved in the pathogenesis of large-vessel vasculitis. Methods: We used IF analysis on aortic and temporal artery biopsies from patients with TA and GCA to assess the involvement of the mTOR pathway and searched for antibodies targeting ECs in serum by IIF and cellular ELISA...

We report an aneurysm degeneration of a vein graft in a previous aortorenal bypass performed five years earlier for severe right renal artery stenosis due to Takayasu arteritis. The patient was a 31-year-old woman who suffered from refractory hypertension. The autogenous bypass adopting great saphenous vein was performed from her infrarenal abdominal aorta to her right renal artery. Five years after the operation, the patient complained vague discomfort in her abdomen. Three-dimensional computed tomography angiography reconstruction demonstrated the existence of an aneurysm with a maximum diameter of 1...

Femoral artery aneurysm is a rare entity among the vascular complications of Takayasu's disease. It is sometimes characterized by the risk of serious local complications with hemorrhagic or ischemic event, as well as by a big therapeutic handling difficulty. We report a case of bilateral femoral artery aneurysm in a 16-year-old girl having a dramatic evolution turn after surgical treatment and irreversible limb ischemia.

Concurrent involvement of bilateral renal and cerebral arteries, usually incurred as stenosis, is rare in childhood-onset Takayasu arteritis (c-TA). We report the case of a 14-year-old girl, with c-TA, presenting with transient ischemic attack after endovascular revascularization for renal artery stenosis and cerebrovascular stroke after surgical revascularization for cerebral artery stenosis associated with childhood-onset moyamoya syndrome. We deem that decrease of blood pressure by endovascular revascularization and improvement of cerebral perfusion by surgical revascularization may have jeopardized the cerebral deep watershed zone to cerebral ischemia followed by cerebral hyperperfusion syndrome and caused transient ischemic attack and cerebrovascular stroke in our patient...

Background: In the global, Phase 3, ASCEND-5 study, ceritinib improved progression-free survival (PFS) vs chemotherapy in patients with anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) who had previously progressed on crizotinib and platinum-based chemotherapy. Here, we report efficacy and safety in a subset of Japanese patients from the ASCEND-5 study. Methods: Patients with advanced ALK-rearranged NSCLC received oral ceritinib 750 mg/day or chemotherapy (intravenous pemetrexed 500 mg/m2 or docetaxel 75 mg/m2 [investigator's choice], every 21 days)...

OBJECTIVES: The commonly adopted method of defining active disease in Takayasu's arteritis (TAK) is the definition used by the US National Institutes of Health (NIH). A gold standard in imaging techniques for assessing disease activity in TAK has not been clearly established and the creation of practical and valid tools represents a challenge. To assess whether 18F-FDG-PET/CT and NIH criteria show a good level of agreement in assessing disease activity of TAK patients. METHODS: 18F-FDG-PET/CT was performed in 17 patients with TAK...

PURPOSE OF REVIEW: Systemic vasculitides are characterized by inflammation of blood vessel walls leading to a myriad of organ disorders depending on the size, site, and location of the affected blood vessel. The epidemiology of vasculitis in the developing world has been inadequately documented. The description of the vasculitides in Africa, both from hospital series as well as taking into consideration, previous epidemiological studies in the community, indicates that these conditions have been rare until relatively recently...
