RESUMEN

BACKGROUND: Next-generation sequencing has greatly increased our understanding of vascular birthmarks. Many port-wine birthmarks are due to somatic mutations in GNAQ/GNA11 exon 183, but other genomic causes have been identified. Most congenital hemangiomas are due to somatic mutations in GNAQ/GNA11 at exon 209. Although genomically distinct, clinical overlap of congenital hemangiomas and port-wine birthmarks has occasionally been described. OBJECTIVE: We report a case series of a unique segmentally distributed vascular anomaly with overlapping characteristics of port-wine birthmarks and congenital hemangiomas with other distinctive features including ulceration, atrophy, and scarring. METHODS: This was a multicenter study with retrospective identification of patients via a detailed review of medical records. We also reviewed previously published cases. RESULTS: The clinical, histological, radiological, and genomic characteristics of 19 new and 13 previously reported cases characterized by segmental distribution, sharply demarcated borders, with variable thickening are presented. All cases had central atrophy with or without episodic ulceration. Those with genomic studies (13 out of 32) had somatic activating missense mutations in GNA11 or GNAQ codon 209. CONCLUSIONS: We describe the features and propose a descriptive name segmental congenital vascular anomaly with atrophy, ulceration, and scarring (SeCVAUS) for this condition.

RESUMEN

BACKGROUND: Early specialist evaluation during rapid proliferative growth of complicated infantile hemangiomas (IHs) is crucial. Health disparities and barriers of access to care for children with IHs have not been examined. OBJECTIVE: To investigate whether socioeconomic status (SES) is associated with age at presentation to a subspecialist for IH evaluation. METHOD: A retrospective cohort study of 804 children presenting to a large academic hospital. The primary outcome was age at initial presentation. Covariates included demographic, socioeconomic, geographic, and clinical characteristics. Medicaid and the Children's Health Insurance Program were proxies for lower SES. Analysis of covariance, chi-square tests, and generalized ordered logistic regressions were performed. RESULTS: Children with lower SES had higher odds of presenting after 3 months of age (odds ratio, 2.11; 95% confidence interval, 1.31-3.38). In the subset that qualified for the institutional care management program (ICMP), no risk factors were associated with delayed presentation. LIMITATIONS: Use of insurance and economic distress as proxies for SES; exclusion of uninsured children, which may have resulted in underestimation of racioethnic effects; and examination of a single academic center, which may limit generalizability. CONCLUSIONS: Children with IHs and lower SES were more likely to present later to specialists, but those enrolled in an ICMP were not, suggesting that integrated ICMPs may mitigate disparities and delayed access to care for IHs among lower-SES populations.

RESUMEN

BACKGROUND: Initial propranolol recommendations for infantile hemangioma published in 2013 were intended as provisional best practices to be updated as evidence-based data emerged. METHODS: A retrospective multicenter study was performed to evaluate utility of prolonged monitoring after first propranolol dose and escalation(s). Inclusion criteria included diagnosis of hemangioma requiring propranolol of greater than or equal to 0.3 mg/kg per dose, younger than 2 years, and heart rate monitoring for greater than or equal to 1 hour. Data collected included demographics, dose, vital signs, and adverse events. RESULTS: A total of 783 subjects met inclusion criteria; median age at initiation was 112 days. None of the 1148 episodes of prolonged monitoring warranted immediate intervention or drug discontinuation. No symptomatic bradycardia or hypotension occurred during monitoring. Mean heart rate change from baseline to 1 hour was -8.19/min (±15.54/min) and baseline to 2 hours was -9.24/min (±15.84/min). Three preterm subjects had dose adjustments because of prescriber concerns about asymptomatic vital sign changes. No significant difference existed in pretreatment heart rate or in heart rate change between individuals with later adverse events during treatment and those without. CONCLUSION: Prolonged monitoring for initiation and escalation of oral propranolol rarely changed management and did not predict future adverse events. Few serious adverse events occurred during therapy; none were cardiovascular.

RESUMEN

The COVID-19 pandemic has caused significant shifts in patient care including a steep decline in ambulatory visits and a marked increase in the use of telemedicine. Infantile hemangiomas (IH) can require urgent evaluation and risk stratification to determine which infants need treatment and which can be managed with continued observation. For those requiring treatment, prompt initiation decreases morbidity and improves long-term outcomes. The Hemangioma Investigator Group has created consensus recommendations for management of IH via telemedicine. FDA/EMA-approved monitoring guidelines, clinical practice guidelines, and relevant, up-to-date publications regarding initiation and monitoring of beta-blocker therapy were used to inform the recommendations. Clinical decision-making guidelines about when telehealth is an appropriate alternative to in-office visits, including medication initiation, dosage changes, and ongoing evaluation, are included. The importance of communication with caregivers in the context of telemedicine is discussed, and online resources for both hemangioma education and propranolol therapy are provided.

RESUMEN

BACKGROUND/OBJECTIVES: First-line therapy for infantile hemangiomas (IH) is oral propranolol, a systemic beta-blocker with the risk of rare but serious adverse effects. Topical timolol presents an attractive off-label alternative with good tolerability, but sequential therapy with propranolol followed by timolol is not well studied. Here, we report effects of topical timolol preceding or following oral propranolol as adjunct therapy for IH. METHODS: A retrospective chart review of 559 patients with IH seen at the pediatric dermatology clinic of a tertiary care center between December 2008 and January 2018. Children were grouped by treatment received: propranolol only, timolol only, propranolol to timolol, timolol to propranolol to timolol, and timolol to propranolol. Patient demographics, clinical/treatment characteristics, and pairwise differences were explored between groups. RESULTS: Among all patients treated with propranolol, those who received propranolol followed by timolol received the shortest duration of oral propranolol and were the youngest at the time of propranolol completion. These patients received propranolol for a median of 2.2 months duration (P = 0.006) and were a median of 1.7 months younger (P = 0.007) compared with patients who received oral propranolol only. None had treatment failure defined as requiring propranolol reinitiation, compared with 13% of patients in the propranolol only group (P = 0.036). CONCLUSIONS: Sequential therapy with oral propranolol followed by topical timolol for IH may help minimize potential adverse effects of systemic beta-blockers by reducing the duration of propranolol therapy and facilitating successful taper at a younger age without an increase in treatment failures.

RESUMEN

OBJECTIVES: To identify clinical factors associated with complications of periocular infantile hemangioma (IH) and monitor improvement in complication rates post-treatment. METHODS: Retrospective cohort study. Eighty-nine patients diagnosed with periocular IH at a pediatric dermatology clinic of a tertiary care center between 2001 and 2013 were included with parental approval. Parents were interviewed by telephone between July and September of 2015, then again in January 2018 to inquire about ophthalmologic follow-up. Electronic medical records were reviewed from January 2001 through January 2018. RESULTS: Sixty percent of patients demonstrated ocular sequelae, including astigmatism (33%), visual axis obstruction (29%), nasolacrimal duct obstruction (7%), ptosis (4%), amblyopia (3%), and strabismus (1%). Compared with superficial IH, deep and mixed IH had higher odds, 3.4 (P = 0.025) and 3.8 (P = 0.034), respectively, of developing ocular sequelae. All patients with astigmatism prior to involution of IH received systemic therapy, with a significant post-treatment decrease in the proportion of patients with astigmatism (40% to 18%, P = 0.027). Three-quarters of patients experienced complete IH involution by time of enrollment in kindergarten. Fifty-one (57.3%) patients received formal ophthalmologic evaluation confirmed through chart review or phone interview, with average follow-up duration of 51.2 months (range: 1.9, 99.3). CONCLUSION: Deep and mixed IH were more likely to demonstrate ocular complications than superficial IH. Rate of astigmatism decreased with systemic therapy. Our study suggests that patients with periocular IH have a lower rate of amblyopia now compared with the prepropranolol era and emphasizes the importance of early treatment of periocular IH to prevent permanent visual sequelae.

RESUMEN

BACKGROUND: Arteriovenous malformations (AVMs) are high flow vascular anomalies that are difficult to manage given their high recurrence rate. At this time, the optimal treatment of AVMs involves embolization and surgical resection. However, few studies have examined patient outcomes after a delayed surgical resection approach. METHODS: A retrospective chart review of all patients presenting to a single institution with vascular malformations from 2000 to 2016 was performed. Patients with facial AVMs that underwent operative management were included. Records were reviewed for patient characteristics, lesion natural history, operative timing after embolization (<72 vs >72 hours), and outcomes. RESULTS: 11 patients fulfilled the inclusion/exclusion criteria. Nine patients were female, with an average age at resection of 29.1 years. Three patients had hemi/mid-facial AVMs, 1 patient had a nasal AVM, 3 patients had labial AVMs, 1 patient had an AVM on the chin, and 1 had a periorbital AVM. Average time between embolization and primary resection was 8.6 days (range 1-24). No complications requiring reoperation occurred in any patient. Average follow-up was 32.6 months, with 2 recurrences at a mean of 47.6 months. Timing of resection, Schobinger stage, and resection completeness did not significantly affect recurrence (P >0.05). Lesion size >6 cm in any dimension was significantly associated with recurrence (P = 0.018). CONCLUSION: Compared to early resection, delayed (>72 h) surgical resection after embolization of facial AVMs is a viable treatment option and results in non-inferior recurrence rates (25 vs 14% respectively over a 40-month period).

RESUMEN

The most common causes of chronic nocturnal itching in children are atopic dermatitis and psoriasis, with lichen simplex chronicus and prurigo nodularis contributing to lesser degrees. Despite the prevalence of nocturnal itching, its pathophysiology remains poorly understood. The most troubling consequence of itching at night is poor quality of sleep. Poor sleep quality in children with nocturnal itching has been linked to adverse neurocognitive, behavioral, and physiologic outcomes, including poor performance in school, attention deficit hyperactivity disorder, short stature, hypertension, obesity, and impaired immune function. There is no consensus on the best management of nocturnal itching in children. We conducted a review of the literature evaluating the efficacy of various treatment options for children with chronic nocturnal pruritus. Our review found three recently conducted randomized controlled trials and one case report demonstrating the efficacy of topical corticosteroids, oral melatonin, and clonidine in reducing nocturnal itching or improving sleep quality in children with nocturnal pruritus. Future research is needed to elucidate the pathophysiology of nocturnal itching to best develop targeted, effective treatment strategies.

RESUMEN

BACKGROUND: This study examines the clinical characteristics and demographics of teenage boys with horizontal striae distensae of the lower back in an outpatient setting. METHODS: Retrospective medical chart reviews and telephone survey studies were completed on an outpatient cohort of 12 boys 11 to 17 years of age with a clinical diagnosis of transverse striae distensae of the lower back at a single-center, university-based, pediatric dermatology practice. We evaluated the clinical features of the striae, participant demographic characteristics, and past medical history. A review of the literature concerning risk factors was conducted using PubMed and Google Scholar. RESULTS: Of the 14 patients we contacted, 12 agreed to participate. The average age of onset for the striae was 14.3 years. All boys were above the 50th percentile in height at the time of onset. Eight (66.7%) reported a significant growth spurt before the appearance of the stretch marks. Most were asymptomatic. None of the boys had a history of unmonitored exogenous steroid use or prior infection with Bartonella henselae or Borrelia burgdorferi. Only one (8.3%) had a chronic medical condition. Eleven (91.7%) had at least one first-degree relative with striae distensae. CONCLUSION: Our results indicate that horizontal striae distensae of the lower back in adolescent boys is associated with a rapid growth spurt, tall stature, and family history of striae distensae. There is no association between this type of striae distensae and any chronic medical condition, bacterial infection, or exogenous steroid use. Thus a careful review of systems and counseling without further medical testing is reasonable management.

RESUMEN

BACKGROUND/OBJECTIVES: Nasal infantile hemangiomas (IHs) pose serious medical complications and psychosocial stress if tumor involution is incomplete or prolonged. The objective was to determine which IH characteristics are associated with complications and are predictive of outcome, assessed as the presence of IHs or residual skin changes upon kindergarten entry, to better manage these lesions and counsel families. METHODS: A retrospective chart review of all patients seen in the Division of Pediatric Dermatology at Johns Hopkins Medicine between 2001 and 2014 for nasal IHs (N = 89) was performed. A follow-up telephone interview with parents was conducted in June and July 2014. RESULTS: Complications were observed in 39% of patients. Segmental and indeterminate IHs were more likely to have complications than focal IHs (p = 0.01). Mixed IHs were more likely to ulcerate than deep or superficial IHs (p = 0.01). Eighty percent of patients had treatment and 19% had surgery. Although IHs regressed by kindergarten entry in 70% of patients, 78% of these patients had residual skin changes. Mixed and superficial IHs left more residua than deep IHs (p = 0.04). A statistical comparison of treatments with respect to outcome at kindergarten entry could not be made because subgroups were too small and heterogeneous. CONCLUSION: Nasal IHs had higher rates of complications and treatment than previous reports of IHs at all body sites. Lesions of segmental and indeterminate type and mixed depth should be identified as high risk and treated accordingly. Parents may be counseled that most nasal IHs involute by kindergarten but leave residua and that early referral for treatment may be important for the best outcome.

RESUMEN

To systematically review the literature evaluating efficacy and adverse events of propranolol treatment for infantile hemangiomas, we searched the MEDLINE and Cochrane databases for all studies examining the response of infantile hemangiomas (IHs) to propranolol published between June 12, 2008, and June 15, 2012. Forty-one studies with 1,264 patients were included; 74% of patients were female and approximately 30% had received other treatments before propranolol. Propranolol was initiated at a mean age of 6.6 months at a mean dose of 2.1 mg/kg/day and for a mean treatment duration of 6.4 months. The response rate for patients with IHs treated with propranolol was 98% (range 82%-100%), with response rate defined as any improvement with propranolol. Treatment response rates were comparable for studies evaluating IHs at specific sites, such as periorbital IHs. Studies that followed patients after treatment completion reported IH rebound growth in 17% of patients. There were 371 adverse events reported in 1,189 patients. The most common adverse events were changes in sleep (n = 136) and acrocyanosis (n = 61). Serious adverse events were rare, with reports of symptomatic hypotension in five patients, hypoglycemia in four, and symptomatic bradycardia in one. This systematic review of 1,264 patients treated with propranolol for IHs showed a high rate of efficacy and a low rate of serious adverse events.

RESUMEN

OBJECTIVES: We sought to determine the effect of propranolol on cardiovascular and blood glucose parameters in infants with symptomatic infantile hemangiomas who were hospitalized for initiation of treatment, and to analyze adverse effects of propranolol throughout the course of inpatient and outpatient treatment. METHODS: A retrospective cohort analysis was performed on 50 infants (age less than 12 months) with symptomatic infantile hemangiomas who were hospitalized for propranolol initiation between 2008 and 2012. Demographic data and disease characteristics were recorded. Systolic and diastolic blood pressures, heart rate, blood glucose values, and adverse events recorded during hospitalization were analyzed. An additional cohort of 200 consecutively treated children was also assessed for adverse events associated with outpatient propranolol use. RESULTS: The median age among the inpatient cohort was 3.4 months (range, 0.8 to 12.0 months). Infants older than 6 months were more likely to exhibit bradycardia than were younger infants (p < 0.001). Hypotensive and/or bradycardic periods were infrequent and were not associated with observable clinical symptoms. The mean systolic and diastolic blood pressures and the mean heart rate decreased significantly from day 1 of hospitalization to day 2 (p = 0.004; p = 0.008; p < 0.001), but not from day 2 to day 3, when the propranolol dose was increased to target. Hypoglycemia was rare (0.3% incidence.) Among the 250 outpatients, 2 infants developed lethargy and hypoglycemia during a viral illness and recovered without sequelae. One infant experienced recurrent bronchospasm with viral illnesses and required concomitant bronchodilator therapy. CONCLUSIONS: Frequent deviations from normal ranges of blood pressure and heart rate occur upon initiation of propranolol, but are clinically asymptomatic. These findings support that outpatient initiation of propranolol in healthy, normotensive infants appears to be a relatively safe alternative to inpatient initiation. Hypoglycemia is rare, but can occur throughout the treatment period; parent counseling is of paramount importance.

RESUMEN

OBJECTIVE: To highlight an association of facial segmental hemangiomas with gastrointestinal bleeding in infants with infantile hemangiomas. STUDY DESIGN: We conducted a multicenter retrospective case series study. RESULTS: Ten female patients met study inclusion criteria; 8 were Caucasian, 9 had a facial segmental hemangioma, and 9 cases met the diagnostic criteria for definitive posterior fossa malformations, hemangioma, arterial lesions, cardiac anomalies/coarctation of the aorta and eye abnormalities syndrome with abnormalities of the aorta and cerebral arteriopathy. Severe gastrointestinal bleeding requiring blood transfusion occurred in 9 cases, with age at presentation of gastrointestinal bleeding ranging from 8 days to 6 months. When detected, the location of the hemangioma in the small intestine was in the distribution of the superior mesenteric artery. More than one agent was required to control the gastrointestinal bleeding, including oral or intravenous steroids, vincristine, oral propranolol, interferon, and resection of the small intestine. All cases needed ongoing support care with red blood cell transfusions. CONCLUSIONS: Gastrointestinal bleeding is a rare complication of true infantile hemangioma. The segmental pattern of the cutaneous hemangioma associated with gastrointestinal bleeding should suggest a segmental infantile hemangioma of the lower gastrointestinal tract.

RESUMEN

Infantile hepatic hemangioma is the most common benign liver tumor during infancy. Prompt diagnosis and timely institution of therapy are of utmost importance. Magnetic resonance imaging (MRI) plays a key role in the correct diagnosis and monitoring of treatment. We report on a 15-week-old girl with multifocal infantile hemangiomas of the liver and high output congestive heart failure. Diagnosis was confirmed by MRI. Subsequent treatment with propranolol and steroids showed dramatic regression of the lesions within 24 weeks. We present the characteristic MRI findings and discuss treatment options together with a comprehensive review of the relevant literature. Conclusion Propranolol appears highly efficacious in the management of infantile hepatic hemangioma; dedicated MRI is essential in confirming the diagnosis and monitoring of treatment.

RESUMEN

There have been significant recent advances in the past several years in the field of neurocutaneous vascular syndromes, including the development of more stringent diagnostic criteria for PHACE syndrome, the renaming of macrocephaly-cutis marmorata telangiectatica congenita to macrocephaly-capillary malformation to accurately reflect the true nature of the syndrome, and discovery of new genetic mutations such as RASA-1. There have also been advances in the understanding and management of Sturge-Weber syndrome.PHACE syndrome is a constellation of neurologic, arterial, cardiac, ophthalmologic, and sternal abnormalities associated with infantile hemangiomas. PHACE is an acronym for Posterior fossa malformation, Hemangioma, Arterial anomalies, Coarctation of the aorta, Eye abnormalities. Some authors include an "S" for PHACE(S) to denote the association of ventral defects including Sternal clefting and Supraumbilical raphe.The accurate diagnosis and work-up of these patients require coordination of care across multiple disciplines, including neuroradiology, radiology, dermatology, neurology, surgery, and interventional radiology, among others.This paper is meant to update clinicians and researchers about important advances in these rare, important vascular syndromes, to improve care, and lay the foundation for future directions for research.

RESUMEN

PURPOSE: Vascular anomalies most frequently present at birth or in early childhood, and the craniofacial region is the most common site of involvement. A long history of misleading nomenclature born of confusion about the presentation and natural history of various vascular anomalies has made appropriate diagnosis difficult. The present article emphasizes the importance of clarity of nomenclature for proper diagnosis, both clinically and radiographically, to guide appropriate therapy. In addition, updates on clinical concepts, imaging, and treatment strategies will be discussed. Pediatric vascular anomalies can be divided into two broad categories: vascular tumors and vascular malformations. This biologic classification is based on differences in natural history, cellular turnover, and histology. An updated classification was introduced in 1996 by the International Society for the Study of Vascular Anomalies (ISSVA) to include infantile hemangioma variants, other benign vascular tumors, and combined lesions. Widespread confusion propagated throughout the literature and in clinical practice stems from the continued improper use of many of the terms used to describe vascular tumors and malformations ignoring their pathophysiology. This leads to errors in diagnosis and the dissemination of misinformation to patients and clinicians. Certain terms should be abandoned for more appropriate terms. The clinical presentation usually identifies what general type of vascular anomaly is present, either vascular tumor or vascular malformation. Imaging provides crucial information about the initial diagnosis and aids in follow-up. CONCLUSIONS: Adoption and use of uniform nomenclature in the ISSVA classification system is the first vital step in correct diagnosis and treatment of often complicated vascular tumors and vascular malformations. A multidisciplinary team approach is necessary to provide optimal care for patients, and the necessity for specialists in all areas to communicate using standardized terminology cannot be overemphasized.

RESUMEN

Importance: Oral propranolol is widely considered to be first-line therapy for complicated infantile hemangioma, but its use in patients with PHACE (posterior fossa malformations, hemangioma, arterial anomalies, cardiac defects, eye anomalies) syndrome has been debated owing to concerns that the cardiovascular effects of the drug may increase the risk for arterial ischemic stroke. Objective: To assess the incidence of adverse events among patients with PHACE syndrome receiving oral propranolol for infantile hemangioma. Design, Setting, and Participants: This multicenter retrospective cohort study assessed the incidence of adverse events among 76 patients with PHACE syndrome receiving oral propranolol for infantile hemangioma at 11 tertiary care, academic pediatric dermatology practices. Medical records from January 1, 2010, through April 25, 2017, were reviewed. Exposures: Patients received oral propranolol, 0.3 mg/kg/dose or more. Main Outcomes and Measures: The main outcome was the rate and severity of adverse events occurring throughout the course of treatment with oral propranolol, as documented in the medical records. Adverse events were graded from 1 to 5 using a scale derived from the Common Terminology Criteria for Adverse Events and were considered to be serious if they were grade 3 or higher. Results: A total of 76 patients (59 girls and 17 boys; median age at propranolol initiation, 56 days [range, 0-396 days]) met the inclusion criteria. There were no reports of serious adverse events (ie, stroke, transient ischemic attack, or cardiovascular events) during treatment with oral propranolol. A total of 46 nonserious adverse events were reported among 29 patients (38.2%); the most commonly reported nonserious adverse events were sleep disturbances and minor gastrointestinal tract and respiratory tract symptoms. In a comparison with 726 infants who received oral propranolol for hemangioma but did not meet criteria for PHACE syndrome, there was no significant difference in the rate of serious adverse events experienced during treatment (0 of 76 patients with PHACE syndrome and 3 of 726 patients without PHACE syndrome [0.4%]). Conclusions and Relevance: This study found that oral propranolol was used to treat infantile hemangioma in 76 patients with PHACE syndrome and that no serious adverse events were experienced. These data provide support for the safety of oral propranolol in this patient population.

RESUMEN

CASE: We describe a 13-year-old girl with bilateral symmetric eccrine angiomatous hamartoma (EAH) on the volar aspect of the wrists. The lesions were painless and had been enlarging progressively for 1 year; the enlargement of the nodule on the right wrist was more substantial than that on the left wrist. She had palmar hyperhidrosis, which has a known association with EAH. CONCLUSION: To our knowledge, bilateral symmetric EAH has been reported only 3 other times in the literature. In all 3 of these cases, the lesions were on the dorsum of the hands or the wrists. We believe that this is the first report of this rare presentation on the volar aspect of the wrist. The symmetry suggests that the lesions may be the manifestation of a systemic or mechanical cause.
