Background: Spontaneous intracerebral hemorrhage (ICH) is the second most prevalent subtype of stroke and has high mortality and morbidity. The utility of radiographic features to predict secondary brain injury related to hematoma expansion (HE) or increased intracranial pressure has been highlighted in patients with ICH, including the computed tomographic angiography (CTA) spot sign and intraventricular hemorrhage (IVH). Understanding the pathophysiology of spot sign and IVH may help identify optimal therapeutic strategies. We examined factors related to the spot sign and IVH, including coagulation status, hematoma size, and location, and evaluated their prognostic value in patients with ICH.
Methods: Prospectively collected data from a single center between 2012 and 2015 were analyzed. Patients who underwent thromboelastography within 24 h of symptom onset and completed follow-up brain imaging and CTA within 48 h after onset were included for analysis. Multivariate logistic regression analyses were performed to identify determinants of the spot sign and IVH and their predictive value for HE, early neurological deterioration (END), in-hospital mortality, and functional outcome at discharge.
Results: Of 161 patients, 50 (31.1%) had a spot sign and 93 (57.8%) had IVH. In multivariable analysis, the spot sign was associated with greater hematoma volume (odds ratio [OR] 1.02; 95% confidence interval [CI] 1.00-1.03), decreased white blood cell count (OR 0.88; 95% CI 0.79-0.98), and prolonged activated partial thromboplastin time (OR 1.14; 95% CI 1.06-1.23). IVH was associated with greater hematoma volume (OR 1.02; 95% CI 1.01-1.04) and nonlobar location of hematoma (OR 0.23; 95% CI 0.09-0.61). The spot sign was associated with greater risk of all adverse outcomes. IVH was associated with an increased risk of END and reduced HE, without significant impact on mortality or functional outcome.
Conclusions: The spot sign and IVH are associated with specific hematoma characteristics, such as size and location, but are related differently to coagulation status and clinical course. A combined analysis of the spot sign and IVH can improve the understanding of pathophysiology and risk stratification after ICH.

Background: Leopard spots can appear in a variety of diseases; however, they are extremely rare in children with rhegmatogenous retinal detachment. This study presents two such rare cases in which leopard spot retinopathy was the initial manifestation of rhegmatogenous retinal detachment.
Case Presentation: Case 1 involved a 4-year-old boy had previously been diagnosed with left eye uveitis and received systemic steroid therapy at a local hospital, but symptoms persisted.

Introduction: The ocular ultrasound spot sign negatively predicts the success of thrombolytic treatment in retinal arterial occlusions. We evaluated the presence of the spot sign in these patients.
Material And Methods: Retrospective study of patients with acute central retinal artery occlusion (CRAO) or its branches (BRAO).

Objective: White spot lesions are initial sign of enamel caries that compromise esthetic appearance following orthodontic treatment. Thus, the systematic review was conducted to evaluate the remineralization potential of orthodontic adhesives on early-enamel lesions surrounding orthodontic bracket.
Methods: Search strategy was performed through three databases (PubMed, Web of Science, and Scopus).
