Introduction: Severity of vascular damage of white matter may predict hemorrhagic transformation (HT). We assess the relationship between leukoaraiosis (LA) severity and the type of hemorrhagic transformation in elderly patients treated with thrombolysis.
Methods: We retrospectively analyzed the clinical data and pretreatment magnetic resonance imaging (MRI) of 180 consecutive ischemic stroke patients aged over 75 years. LA severity was graded according to the Fazekas scale, and acute diffusion-weighted-imaging (DWI) lesion volumes were semi-automatically outlined. Predictors of hemorrhagic infarction (HI) and parenchymal hemorrhage (PH) were identified using logistic regression analysis and exact multinomial logistic analysis.
Results: HT occurred in 31 patients (17 %). Baseline National Institute of Health Stroke Score (NIHSS; p = 0.008), severe LA (p = 0.02), and diffusion lesion volume (p = 0.02) were predictors of HT in univariable logistic regression. Adjusted to lesion volume and baseline NIHSS score, exact multinomial logistic analysis showed that severe LA was the only independent predictor of parenchymal hemorrhage (p = 0.03).
Conclusion: In elderly patients, LA severity better predicts parenchymal hemorrhage than infarct size.

Background And Purpose: Up to 80% of patients diagnosed with reversible cerebral vasoconstriction syndrome (RCVS) experience complications such as ischaemic stroke, intracerebral or subarachnoid haemorrhage or posterior reversible encephalopathy syndrome. The aim was to evaluate the incidence of complications in patients diagnosed with RCVS in our clinic.
Patients And Methods: All adult patients (age >16 years) diagnosed with RCVS at the Helsinki University Central Hospital during the period between 1 January 2016 and 31 December 2022 were retrospectively identified.

During development, endothelial cells (ECs) undergo an extraordinary specialization by which generic capillary microcirculatory networks spanning from arteries to veins transform into patterned organotypic zonated blood vessels. These capillary ECs become specialized to support the cellular and metabolic demands of each specific organ, including supplying tissue-specific angiocrine factors that orchestrate organ development, maintenance of organ-specific functions and regeneration of injured adult organs. Here, we illustrate the mechanisms by which microenvironmental signals emanating from non-vascular niche cells induce generic ECs to acquire specific inter-organ and intra-organ functional attributes.

The objective of our study was to describe the clinical, etiological, radiological, therapeutic, and evolutionary characteristics of children with CVT in western Algeria.
Methods: This was a retrospective observational study involving children with CVT.

Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.
Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.

Introduction: Diffuse parenchymal lung diseases (DPLD) cover heterogeneous types of lung disorders. Among many pathological phenotypes, pulmonary fibrosis is the most devastating and represents a characteristic sign of idiopathic pulmonary fibrosis (IPF). Despite a poor prognosis brought by pulmonary fibrosis, there are no specific diagnostic biomarkers for the initial development of this fatal condition.
