Our study will clarify whether angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers are more effective for preventing primary and recurrence of ischemic stroke, including the progression of asymptomatic cerebral lesions on magnetic resonance imaging, in elderly hypertensive patients.
A 69-year-old man presented with upper airway symptoms, multiple lung nodules and masses, proteinuria and hematuria, and an increased level of proteinase 3 anti-neutrophil cytoplasmic antibody (PR3-ANCA). Granulomatosis with polyangiitis (GPA) was diagnosed by a transbronchial lung biopsy. All of these symptoms were ameliorated and the level of PR3-ANCA declined following treatment with prednisolone and cyclophosphamide. The patient developed a headache 16 months after the onset of symptoms, and contrastenhanced magnetic resonance imaging showed the thickening of the dura mater, which suggested that hypertrophic pachymeningitis (HP) had developed as a complication of GPA. HP can be a unique complication of GPA at recurrence, and can occur without the relapse of other lesions or an increase in PR3-ANCA level.
A 19-year-old girl was admitted to our hospital with nausea, vomiting, hiccups, constipation and syncope. After hiccups or vomiting sinus arrest developed and lasted more than 5-8 seconds. She lost consciousness every one hour. Based on an electrocardiographic diagnosis of sick sinus syndrome SSS , a temporary pacemaker was implanted. The next day, although her syncope and bradycardia disappeared, she had orthostatic tachycardia of over 120 beats minute and swelling of the legs, which led to a diagnosis of postural orthostatic tachycardia syndrome POTS. Neurologically, she showed the right-sided tongue deviation and parasympathetic system disorders revealed by coefficient of variation of R.R interval CV R R , the Achner eyeball pressure test, the valsalva ratio, and the head-up-tilt test. Brain MRI disclosed a small hyperintense lesion on a T2-weighted image with gadolinium enhancement in the right dorsal medulla including the hypoglottis nucleus and the posterior nucleus of vagus. After steroid pulse therapy methyl prednisolone 1 g day 3 days, 5 times was administered, this lesion became smaller and finally disappeared. Before the lesion disappeared, she was able to begin rehabilitation by wearing elastic stockings and treatment with midodrine hydrochloride. The following year, she developed other MRI-proven brain lesions, suggestive of demyelination. Such a spinal and temporal distribution of lesions led to a diagnosis of multiple sclerosis MS. A case of POTS caused by MS has not been reported previously, however, MS often affects the medullary paraventricular regions associated with autonomic failures. Autonomic failures often prevent patients from experiencing early rehabilitations. We should promptly give symptomatic treatment against autonomic failures, which leads to good patient recovery not only in patient vitality but also functionality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
