Susac syndrome (SS) is a rare retinal-cochlear-cerebral disease with an unclear etiology. A 35-year-old man presented with sudden painless vision loss in the right eye and 2 months later in the left eye with hemiparesis, behavioral changes, and hearing loss. Ophthalmic examinations revealed multiple branch retinal artery occlusions (BRAOs) in both eyes. Brain magnetic resonance imaging showed inflammatory changes with multiple "punched-out" lesions in the corpus callosum which confirmed the diagnosis of SS...

OBJECTIVES: Mechanical circulatory support (MCS) is an established therapy for end-stage heart failure. The EUROMACS registry was created to promote research in patients with MCS and became a committee of the European Association for Cardio-Thoracic Surgery (EACTS) in 2014. Since 1 January 2011, increasing numbers of European centres implanting durable MCS have reported their patient data to EUROMACS. The aim of this study is to compare, as an example of internal quality control, data from a single centre (Bern) with those from the EUROMACS database with respect to mortality rates and preoperative patient characteristics and to describe complications in Bern...

White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). The pathogenesis of many white matter diseases remains poorly understood. Demyelinating disorders are the object of this review and will be further divided into autoimmune, infectious, vascular, and toxic-metabolic processes. Autoimmune processes include multiple sclerosis and related diseases: tumefactive demyelinating lesions, Balo concentric sclerosis, Marburg and Schilder variants, neuromyelitis optica (Devic disease), acute disseminated encephalomyelitis, and acute hemorrhagic leukoencephalopathy (Hurst disease)...

The glucosinolates (GLs) present in seed extracts of Brassica elongata Ehrh., B. botteri Vis and B. cazzae Ginzb. & Teyber from Croatia were identified by LC-MS. 4-Hydroxyindol-3-ylmethyl GL (3) was the major GL in the seeds of B. elongata, along with the four minor GLs 2-(R)-hydroxy-3-butenyl- (1), 3-butenyl- (2), 4-pentenyl- (4) and indol-3-ylmethyl (5). The seeds of B. botteri (Vis island) and B. cazzae (Sušac island) contained 2 as the major GL as well as 1, 3, 5 and 4-methoxyindol-3-ylmethyl GL (6). However, the GLs in B...

Susac syndrome is an endotheliopathy affecting the arterioles of the brain, retina, and inner ear. Many cases of Susac syndrome are underdiagnosed, mainly at the early stages of the disease, while prompt diagnosis enables a speedy recovery. Immediate treatment can halt disease progression and even prevent future disability. We report a case of Susac syndrome, describe the difficulties in the diagnosis of this case, and include a detailed history of a 35-year-old man via the presentation of extensive laboratory work-up and imaging studies...

Rare causes of ischaemic stroke comprise a plethora of diagnoses of cardioembolic, inflammatory and genetic origin. The differential diagnosis is challenging but important because these disorders (e.g. monogenetic disorders such as COL4A1 mutations) often affect young individuals, they typically require sophisticated diagnostics (e.g. fluorescence angiography in Susac's syndrome) and they are increasingly treatable (e.g. enzyme replacement for Fabry's disease). This review discusses practical considerations and recent diagnostic and therapeutic advances in uncommon causes of ischaemic stroke...

BACKGROUND: Susac syndrome (retinocochleocerebral vasculopathy) is an autoimmune endotheliopathy affecting the precapillary arterioles of the brain, retina, and inner ear. It presents with encephalopathy, branch retinal artery occlusions, and hearing loss. The condition is often under recognized because the clinical symptoms may present at different times and physicians may be unfamiliar with the syndrome. Peripheral findings would be helpful in early diagnosis. There are numerous treatment regimens proposed with varying effectiveness...

Magnetic resonance imaging detection of leptomeningeal enhancement has long been considered a red flag for a diagnosis of multiple sclerosis. However, recent studies seem to suggest that leptomeningeal enhancement can be detected in up to 25% of patients with multiple sclerosis. The case reported here suggest a distinct set of features of leptomeningeal enhancement in a patient with Susac's syndrome which may still be helpful in the differential diagnosis between Susac's syndrome and multiple sclerosis.
