Do cutaneous hemangiomas and internal vascular anomalies follow the same evolution?

Abstract

Cluster thinning is practiced to reduce grapevine crop load and advance ripening parameters, such as soluble solids, which may or may not lead to higher quality wine. It is often implemented in the field with little or no specificity, and its practicality has been questioned because of increased production costs and lost yields. New analytical methods are introduced that combine commonly available yield and cost data with estimated parameters for grape quality and willingness-to-pay. The result is a tailored economic model that allows growers to calculate their optimal yields and prices within a rigorous, quantitative decision-making framework.

A comparison of disease severity among affected male versus female patients with PHACE syndrome

“…Although speculative, it is possible that such anomalies were present earlier but regressed, as such regressive phenomena have been rarely reported with both the cerebrovascular and cardiovascular anomalies of PHACE. 3,10 Other vascular findings of interest among our new cases include the dural arteriovenous malformations described in cases 5 and 15. We are aware of only one other report describing high-flow intracerebral arteriovenous malformations in PHACE.…”

Congenital and Evolving Vascular Disorders Associated with Cutaneous Hemangiomas: Case Report

“…Duplication of the vertebral artery associated with cutaneous vascular abnormalities has not been reported to date. Aneurysmal extracranial and intracranial portions of the internal carotid arteries with increased arterial lumen associated with external haemangiomas present a similar process of regression with narrowing of their calibre that can lead to complete closure of the arterial lumen and, at the same time, a transdural collateral vascularisation develops to supply the cerebral hemispheres [6,12] . This process of arterial involution aff ects not only the main angiomatous arteries but also those of middle and small size that develop from the collateral vascularisation as was demonstrated in the present patient.…”

A prospective study of PHACE syndrome in infantile hemangiomas: Demographic features, clinical findings, and complications

“…Case CN-71 was found to have aortic valve and arch hypoplasia that was discovered to have resolved by age 18 months, and UM-3 had distal arch hypoplasia that was found to have resolved by age 1 year (Table III). Another recent publication described a patient with PHACE-associated cerebrovascular anomalies documented in infancy that were discovered by young adulthood to have spontaneously regressed [Pascual-Castroviejo et al, 2003]. This suggests the possibility of both progressive and regressive phenomena within the vascular anomalies of PHACE.…”
