Background:Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic noninflammatory disease characterized by ossification of the entheses.Methods:This paper reviews the etiopathogenesis, epidemiology, clinical features, differential diagnosis, and treatment of DISH, based on current available literature.Results:Exact prevalence and incidence of DISH remains undetermined. Many external and genetic factors have been reported as being contributors to the pathogenesis of DISH. Current theories focus on the pathologic calcification of the anterior longitudinal ligament of the spine as the main physiopathological mechanism of disease. Clinical features are variable from monoarticular sinovitis to airway obstruction, and can be associated to systemic conditions. Comorbidities include obesity, hypertension, diabetes mellitus, hyperinsulinemia, dyslipidemia, and hyperuricemia according to a number of reports.Conclusions:DISH is a disease which involves the calcification of the anterior longitudinal ligament of the spine and can be associated with numerous clinical presentations and comorbidities.
Unilateral carotid cavernous fistula presents with ipsilateral ocular findings. Bilateral presentation is only seen in bilateral fistulas, usually associated with indirect (dural) carotid cavernous fistulas. Direct carotid cavernous fistulas are an abnormal communication between the internal carotid artery and the cavernous sinus. They typically begin with a traumatic disruption in the artery wall into the cavernous sinus, presenting with a classic triad of unilateral pulsatile exophthalmos, cranial bruit and episcleral venous engorgement. We report the case of a 38-year-old male with traumatic right carotid cavernous sinus fistula and bilateral ocular presentation successfully treated by interventional neuroradiology.
Carotid artery dissection is a significant cause of stroke in young patients. It may be asymptomatic and go undiagnosed, or minimal transient manifestations may follow, commanding a higher index of suspicion than ordinarily exists to avoid misdiagnosis. Reported herein is a 27-year-old man who suffered extracranial internal carotid artery dissection while practicing a Brazilian Jiu-Jitsu submission maneuver. The patient's condition suddenly deteriorated one week later due to distal embolization and stroke. Despite endovascular treatment, with stenting of the cervical carotid artery, neurologic deficits remained. Of note, the objective in martial arts, which is to kill or incapacitate, has yet to be fully tempered in transitioning to sport. Brazilian Jiu-jitsu, a relatively new and fast-growing form of martial art, places emphasis on submission maneuvers. Related injuries are not common knowledge and are poorly described in the literature. This account is intended to shed light on the risk of this discipline. Through education and improved supervision, vascular injuries of this nature and the potentially lethal or disabling consequences may thus be prevented in young athletes.
Sneddon syndrome (SS) is a rare progressive non-inflammatory thrombotic vasculopathy affecting small/medium-sized blood vessels of unknown origin. It is strongly associated with the presence of antiphospholipid antibodies (AA). The presence of livedo reticularis and cerebrovascular disease are hallmark features. The condition is far more common in young women. We report a case of SS in a 43 year-old male with a two-year history of progressive cognitive impairment consistent with dementia syndrome, and major personality changes, besides livedo reticularis and cerebral angiographic pattern of vasculitis. AA were borderline. The recognition of skin blemishes that precede strokes should raise the hypothesis of SS. AA are elevated in more than half of cases, but their role in the pathogenesis or association of positive antibodies and SS remains unclear. Dementia syndrome in young patients should be extensively investigated to rule out reversible situations. Typical skin findings, MRI and angiography may aid diagnosis.
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.
