RESUMEN
Infantile hemangiomas (IHs) occur in as many as 5% of infants, making them the most common benign tumor of infancy. Most IHs are small, innocuous, self-resolving, and require no treatment. However, because of their size or location, a significant minority of IHs are potentially problematic. These include IHs that may cause permanent scarring and disfigurement (eg, facial IHs), hepatic or airway IHs, and IHs with the potential for functional impairment (eg, periorbital IHs), ulceration (that may cause pain or scarring), and associated underlying abnormalities (eg, intracranial and aortic arch vascular abnormalities accompanying a large facial IH). This clinical practice guideline for the management of IHs emphasizes several key concepts. It defines those IHs that are potentially higher risk and should prompt concern, and emphasizes increased vigilance, consideration of active treatment and, when appropriate, specialty consultation. It discusses the specific growth characteristics of IHs, that is, that the most rapid and significant growth occurs between 1 and 3 months of age and that growth is completed by 5 months of age in most cases. Because many IHs leave behind permanent skin changes, there is a window of opportunity to treat higher-risk IHs and optimize outcomes. Early intervention and/or referral (ideally by 1 month of age) is recommended for infants who have potentially problematic IHs. When systemic treatment is indicated, propranolol is the drug of choice at a dose of 2 to 3 mg/kg per day. Treatment typically is continued for at least 6 months and often is maintained until 12 months of age (occasionally longer). Topical timolol may be used to treat select small, thin, superficial IHs. Surgery and/or laser treatment are most useful for the treatment of residual skin changes after involution and, less commonly, may be considered earlier to treat some IHs.

In treating thickened port wine stains and superficial venous malformations with the 595 nm pulse dye laser, we have sometimes compressed the lesion with a glass slide to enable the laser beam to penetrate more deeply. In order to evaluate the patients' perception of this modality, 54 subjects were treated with glass compression using ice applications to cool the skin surface and without glass compression using a cryospray to cool the surface. The subjects were asked to rate the difference in 2 questionnaires after the first and second treatments as to effectiveness, pain of procedure, and overall preference. Of those subjects who perceived a difference between modalities, a significant number perceived treatments with glass compression to be more effective than without (p=0.0002 and p=0.0006), but more painful (p<0.0001). There was no significant difference in overall preference. Blistering occurred in 5 subjects when the glass slide was left on the skin more than 1 minute between ice applications.

Vision screening is crucial for the detection of visual and systemic disorders. It should begin in the newborn nursery and continue throughout childhood. This clinical report provides details regarding methods for pediatricians to use for screening.

Various parameters in 91 adult participants with vascular malformations and 91 controls were studied. The mean of the participants' platelet volumes was 8.5 fL and that of their controls was 9.1 (P < .001). The mean of the participants' platelet mass was 2145 µL/L of blood and that of their controls was 2351 (P = .006). The other parameters studied were not significantly different than the controls. It is suggested that the lower platelet volume might be related to a compensatory mechanism to keep the total body platelet mass stable despite the increased vasculature.
