Subarachnoid hemorrhage (SAH) is a common and frequently life-threatening cerebrovascular disease, which is mostly related with a ruptured intracranial aneurysm. Its complications include rebleeding, early brain injury, cerebral vasospasm, delayed cerebral ischemia, chronic hydrocephalus, and also non neurological problems. Non-coding RNAs (ncRNAs), comprising of microRNAs (miRNAs), small interfering RNAs (siRNAs) and long non-coding RNAs (lncRNAs), play an important role in intracranial aneurysms and SAH. Here, we review the non-coding RNAs expression profile and their related mechanisms in intracranial aneurysms and SAH...

We present a patient who developed acute intraoperative cardiac failure requiring open cardiac message immediately after uncomplicated heart transplantation. After successful resuscitation and establishment of extracorporeal membrane oxygenation, coronary angiography showed diffuse multivessel coronary vasospasm, which responded to intracoronary and IV administration of vasodilators. Cardiac function gradually improved and the patient was discharged home after a prolonged hospital course. Cardiac allograft dysfunction associated with coronary vasospasm immediately after heart transplantation has not previously been reported...

Behavioural disturbances are frequently found after aneurysmal subarachnoid haemorrhage (aSAH). Social cognition impairments have been suggested as a possible underlying mechanism for behavioural problems. Also, aSAH is likely to result in damage affecting frontal-subcortical circuits underlying social cognition. Therefore, we aimed to investigate social cognition after aSAH and its associations with behavioural problems (deficits in interpersonal behaviour, apathy, and impaired self-awareness) and focal as well as diffuse brain damage...

Two cases of ruptured blood blister-like internal carotid artery aneurysms for which low flow bypass was sufficient to attain successful treatment of trapping are reported. In the acute stage of rupture, it is troublesome to perform accurate examinations of tolerance to ischemia like balloon occlusion test(BOT)for estimating the required amount of bypass flow. In our cases, X-ray angiography perfusion(XAP)analysis was introduced, which could be performed in a couple dozen seconds without room-to-room transfer of patients, following the ordinary examination of diagnostic digital subtraction angiography...

BACKGROUND: The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications...

BACKGROUND AND PURPOSE: Porphyrias are a group of inherited metabolic disorders resulting from a specific deficiency along the pathway of haem biosynthesis. A clinical classification distinguishes acute from non-acute porphyrias considering the occurrence of life-threatening neurovisceral attacks, presenting with abdominal pain, neuropsychiatric disturbance and neuropathy. Vasospasm is a very rare complication that can occur in all major types of acute porphyria. METHODS: We describe a porphyric crisis with vasospasm in a woman with previously undiagnosed acute porphyria...

Kounis syndrome (KS) is defined as concurrent acute coronary syndrome and allergic or hypersensitivity reactions. Despite being increasingly reported, it is still an underdiagnosed entity. Several medications are already known to result in KS. Amoxicillin/clavulanic acid is a frequently used antibiotic, and its use has been linked with KS. The aim of the present report was to draw attention to rare clinical manifestation of KS following peroral amoxicillin/clavulanate use.

A 53-year-old woman with migraines presented with Hunt-Hess grade 5 and Fisher grade 4 subarachnoid hemorrhage with intraventricular hemorrhage. She experienced severe vasospasm requiring intra-arterial medications. Continued vasospasm and edema resulted in Cushing's triad with profound tachypnea. Three percentage saline was administered twice without improvement. Despite the general practice to wait until complete neurologic deterioration before administering 23.4% saline, it was administered on 2 separate occasions, once after the failure of the 2 boluses of 3% saline and once on the reappearance of Cushing's triad 24 hours later, and on each occasion produced overall clinical improvement...

Hyperthyroidism is well known to be associated with cardiac disease. Delay in making the diagnosis and occurrence of complications are common and are associated with a worse outcome. A 54-year-old male, non-smoker, with no past medical history and no significant family history presented to our hospital with severe left sided chest pain, "crushing" in nature. Electrocardiogram showed ST-segment elevations in the inferior leads. Troponin I level was 0.32 ng/mL (normal range 0-0.05 ng/mL) on presentation. The patient underwent an emergent coronary angiography which showed no evidence of occlusive coronary artery disease...

BACKGROUND: Long-term continuous intra-arterial nimodipine infusion (CIAN) is a rescue therapy option in cases of severe refractory cerebral vasospasm (CV) following acute non-traumatic subarachnoid hemorrhage (SAH). However, CIAN therapy can be associated with relevant side effects. Available studies focus on intracerebral complications, whereas extracerebral side effects are rarely examined. Aim of the present study was to generate descriptive data on the clinical course during CIAN therapy and expectable extracerebral side effects...

High mobility group box 1 protein (HMGB1) has multiple functions, including the maintenance of nucleosomes and the regulation of gene transcription. HMGB1 is released from activated macrophages, resulting in the induction of inflammatory cytokines. Recently, much research about the role of HMGB1 in cerebrovascular disease (CVD) has been reported. In an animal model, HMGB1 neutralization ameliorates brain infarction, there is an early release of HMGB1 from neurons, and HMGB1 antibody attenuates delayed cerebral vasospasm in experimental subarachnoid hemorrhage...
