Right brain hemisphere lesions affecting language functioning in the acute phase of stroke recovery: A Croatian survey.

Unlabelled: Greater empirical and scientific attention is still put on patients with left brain hemisphere (LBH) damage where language impairments are common and expected. In patients with RBH damage, language assessment is therefore rarely done in the acute phase of stroke recovery.

Purpose: To investigate language impairments in the acute phase of stroke using a Croatian standardized language battery for the first time and compare patients with RBH stroke, LBH stroke and healthy individuals.

A multimodal treatment of basilar artery re-occlusion - case report.

Background: Stroke due to basilar artery occlusion (BAO) is a severe neurovascular condition with only recently proven effectiveness of mechanical thrombectomy as treatment. Early re-occlusion of the basilar artery (RE-BAO) is an even more challenging form of stroke to treat, associated with poor outcomes and still no optimal treatment guidelines. There are only a few reported cases covering this topic thus far.

Comparative Targeted Metabolomics of Ischemic Stroke: Thrombi and Serum Profiling for the Identification of Stroke-Related Metabolites.

Ischemic stroke is one of the leading causes of death and permanent disability in the world. Rapid diagnosis and intervention are crucial for reducing its consequences on individuals and societies. Therefore, identifying reliable biomarkers for early detection, prognostics, and therapy can facilitate the early prediction and prevention of stroke.

Epistemic responsibilities in the COVID-19 pandemic: Is a digital infosphere a friend or a foe?

Digital technologies have a significant role in collecting, filtering and disseminating information, allowing for social, healthcare and economic activities even in the context of highly restrictive public health measures in the current COVID-19 pandemic. As personal contact is greatly reduced, they also create a shared informational landscape, allowing for a shared threat response. This is a difficult task, since truthfulness of content that leads to actionable knowledge is impossible to consistently validate.

OPTIC NERVE SHEATH SONOGRAPHY IS A PROMISING TOOL FOR ASSESSMENT OF RAISED INTRACRANIAL PRESSURE IN PATIENTS ADMITTED TO NEUROLOGICAL INTENSIVE CARE UNIT.

Optic nerve sheath diameter (ONSD) enlargement is detectable in traumatic brain injury patients with raised intracranial pressure (ICP). The aim was to assess its value in neurological patients suspected to have increased ICP. Patient clinical imaging data and hospitalization outcome were analyzed.

[CROATIAN GUIDELINES FOR DIAGNOSIS AND MANAGEMENT OF BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV)].

BPPV is generally the most common cause of vertigo, caused by a pinch-off of tiny calcium carbonate crystals (called the otoconia or the otoliths) from the macula utriculi, most frequently due to the degenerative processes or a trauma, whereby the crystals, under the action of gravity in certain head positions coinciding with its direction, arrive to some of the semicircular canals, usually the posterior one, due to the existent anatomical circumstances and relationships, thus creating an inadequate stimulus of the cupular senses while floating through the endolymph and provoking symptoms of a strong and short-term dizziness. Two main clinical forms can be distinguished: canalolythiasis, with an accommodation of otolithic debris in the semicircular canal, and cupulolythiasis, with their location immediately next to the cupular sense. The diagnosis is established by a positive positioning test, Dix-Hallpike for the posterior and the supine roll for the lateral canal.

Stroke Caused by Lung Cancer Invading the Left Atrium.

We describe a 59-year-old stroke patient presented with sudden onset left side weakness and a speech disorder due to a major acute cerebral infarction in the area of the right middle cerebral artery, right posterior cerebral artery, and small infarctions in the area of the left middle and left posterior cerebral artery. For the previous month, the patient had been feeling weak and had no appetite. The patient had not been previously seriously ill.

General recommendations for the management of aneurysmal subarachnoid hemorrhage.

Subarachnoid hemorrhage is a neurologic emergency and a detrimental cerebrovascular event with a high rate of death and complications. Recommendations have been developed and based on literature search, evaluation of the results of large international clinical trials, collective experience of the authors, and endorsed by the Croatian Society of Neurovascular Disorders, Croatian Society of Neurology including Section for Neurocritical Care, Croatian Neurosurgical Society, Croatian Society for Difficult Airway Management and Croatian Medical Association. The aim of these guidelines is to provide current and comprehensive recommendations and to assist physicians in making appropriate decisions in the management of subarachnoid hemorrhage.

Recommendations for the management of medical complications in patients following aneurysmal subarachnoid hemorrhage.

These are evidence based guidelines for the management of medical complications in patients following aneurysmal subarachnoid hemorrhage, developed and endorsed by the Croatian Society of Neurovascular Disorders, Croatian Society of Neurology including Section for Neurocritical Care, Croatian Neurosurgical Society, Croatian Society for Difficult Airway Management and Croatian Medical Association. They consist of recommendations for best monitoring, medical treatment and interventions based on the literature, evaluation of the results of large international clinical trials, and collective experience of the authors.

Acute polyradiculoneuritis syndrome: clinical observations and differential diagnosis.

Guillain-Barré syndrome (GBS) and neuroborreliosis may clinically manifest with symptoms related to acute polyradiculoneuritis. The aim and purpose of this study was analysis of clinical picture in patients with acute polyradiculoneuritis and their differential diagnosis into patients with GBS or meningoradiculoneuritis within the framework of neuroborreliosis. In this retrospective study, medical records of patients with acute polyradiculoneuritis hospitalized at University Department of Neurology, Sestre milosrdnice University Hospital Center during a 4-year period were analyzed.

Basilar impression as a possible cause of cerebellar stroke: case report.

A case is reported of a 72-year-old woman who presented with severe vertigo, vomit, and mild neck and occipital pain. She had a medical history of hypertension, angina pectoris, cholelithiasis, gastric ulcer, pyelonephritis and periodical mild dizziness. Neuroimaging revealed right vertebral artery occlusion, right cerebellar stroke and basilar impression.

Hemispheric asymmetry of visual cortical response by means of functional transcranial Doppler.

We assessed the visual evoked response and investigated side-to-side differences in mean blood flow velocities (MBFVs) by means of functional transcranial Doppler (fTCD) in 49 right-handed patients with severe internal carotid artery (ICA) stenosis and 30 healthy volunteers, simultaneously in both posterior cerebral arteries (PCAs) using 2 MHz probes, successively in the dark and during the white light stimulation. Statistically significant correlation (P = 0.001) was shown in healthy and in patients (P < 0.

Cerebrovascular evoked response to repetitive visual stimulation in severe carotid disease--functional transcranial Doppler study.

Hemodynamic features of the posterior circulation were evaluated by assessing visual evoked response in posterior cerebral artery (PCA) by means of functional transcranial Doppler (fTCD) in 49 patients with high-grade (70%-99%) internal carotid artery (ICA) stenosis or occlusion and 30 healthy subjects. Mean blood flow velocities (MBFV) and mean reaction time (time to peak velocities) (MRT) in each PCA were measured in the dark (closed eyes) and during white light stimulation (opened eyes, looking at the electric bulb), during three consecutive repetitive periods of 1 minute each. In the group of severe carotid disease patients, there was no difference in MRT in PCA during the white light stimulation (P=0.

Visual evoked response in patients with severe carotid disease--functional transcranial doppler study of posterior circulation.

The goal of this study was to evaluate the visual evoked response in posterior cerebral artery (PCA) by means of functional transcranial doppler in patients with severe carotid disease and to determine the hemodynamic effect of severe carotid disease on posterior circulation. Measurements were performed successively in the dark and during the white light stimulation in 49 patients with high-grade (70-99%) internal carotid artery (ICA) stenosis or occlusion and compared with 30 healthy age and sex matched subjects. Mean blood flow velocities (MBFV) (cm/s +/- 2SD) and mean reaction time (MRT) (s +/- 2SD) during three consecutive repetitive periods of 1 minute each were analyzed.

The art: neuroscientific approach.

Scientists have for centuries tried to localize and define artistic talent. Modern diagnostic techniques that enable visualization and measurement of brain morphology and function are positron emission tomography (PET), magnetic resonance imaging (MRI), functional transcranial Doppler (fTCD) and some biochemical methods. In the majority of people, the left hemisphere is dominant, but the right hemisphere is considered to be creative, visual, imaginative and intuitive.

Stroke unit--where all stroke patients should be treated.

Acute stroke is one of the leading causes of morbidity and mortality worldwide, and as the most important cause of morbidity and long-term disability imposes an enormous economic burden. Stroke units (SU) are an effective option to fight stroke. According to the European Stroke Organization, SU should provide coordinated multidisciplinary care provided by medical personnel specialized in stroke care.

Thrombolysis for acute ischemic stroke--our experiences as part of SITS-MOST.

Thrombolysis with intravenous recombinant tissue plasminogen activator (rtPA) is the first evidence based treatment for acute ischemic stroke, which aims to reduce the cerebrovascular lesion. At University Department of Neurology, Sestre milosrdnice University Hospital, Zagreb, thrombolytic therapy with intravenous rtPA (alteplase) (Actilyse) for acute ischemic stroke was introduced in 2004. We present our results referring to demographic, time logistics and clinical outcome data as part of SITS-MOST (Safe Implementation of Thrombolysis in Stroke - MOnitoring STudy) and compare them with the results from other centers in Croatia and all other participating centers.
