Effect of propranolol vs prednisolone vs propranolol with prednisolone in the management of infantile hemangioma: a randomized controlled study

Infantile hemangiomas: a dermatologist's perspective

Infantile hemangioma (IH), the most common vascular tumor in pediatrics, is thought to arise from aberrant stem cell responses to stimuli such as hypoxia. This review explores the diverse manifestations, complications, and management strategies for IH, emphasizing the importance of a multidisciplinary approach. The epidemiology and risk factors associated with IH, including connections to prematurity, low birth weight, and family background, are discussed. The intricate pathogenesis involving hemangioma stem cells, KIAA1429, hypoxia, and the renin-angiotensin system is examined. The natural history and clinical features, as well as extracutaneous involvements such as hepatic IH, PHACES syndrome, and LUMBAR syndrome, are detailed. Complications such as ulceration, functional impairment, hypothyroidism, and cosmetic concerns are highlighted. The differential diagnosis and diagnostic modalities, including colorimeters, high-frequency ultrasonography, and imaging techniques, are discussed. Management approaches, including the use of propranolol, atenolol, corticosteroids, alternative systemic treatments, topical therapy, laser therapy, and surgery, are comprehensively reviewed. The evolving landscape of IH management is underscored, with ongoing research exploring alternative treatments and individualized approaches based on IH characteristics.

Medical Management of Nonmalignant Vascular Tumors of the Head and Neck: Part 1

Vascular anomalies, broadly classified as nonmalignant tumors and malformations, consist of a multitude of disorders that have a wide range of symptoms and complications as well as overlapping clinical, radiologic, and histologic findings. Although usually difficult, distinguishing between nonmalignant vascular tumors and malformations, as well as the precise diagnosis within these distinctions, is critical because prognosis, therapy, and chronicity of care vary greatly. In contrast to normal endothelial turnover in vascular malformations, vascular tumors are characterized by the abnormal proliferation of endothelial cells and aberrant blood vessels.

Safety of oral propranolol for neonates with problematic infantile hemangioma: a retrospective study in an Asian population

Although the efficacy of propranolol in the treatment of infantile hemangioma (IH) has been well established, clinical data on the safety and tolerability of propranolol in neonates are still lacking. In this work, clinical data of 112 neonates with IH were analyzed retrospectively. All of the patients were evaluated in the hospital at the beginning of the treatment and later in outpatient settings during the treatment. Each time, the following monitoring methods were applied: physical examination, ultrasound echocardiography (UCG), electrocardiography (ECG), blood pressure (BP), heart rate (HR), and basic laboratory tests including blood glucose (BG), liver function, blood potassium, thyroid function. There was a significant reduction in BP and HR at the initiation of treatment. The incidences of bradycardia and hypoglycemia were observed to be increased with the prolong duration of treatment, but not prolonged PR interval. During the course of the therapy, the risk of hyperkalemia and hypothyroidism was reached maximum at the 2 months and 3 months, respectively. Physical growth index including average height, weight and head circumference was not influenced by the treatment. The observed adverse effects were majority mild and only 3 patients needed to rest for 7 days due to severe diarrhea before restarting treatment. This study demonstrated that propranolol is safe and well-tolerated by properly selected young infants with IH. No serious adverse events were observed.

Apelin Receptor Can Act as a Specific Marker and Promising Therapeutic Target for Infantile Hemangioma

Infantile hemangioma (IH), the most common benign tumor in infancy, is generally sensitive to propranolol treatment. However, the challenge remains because resistance or recurrence could occur in some patients, and the mechanism or target of propranolol remains unknown. Therefore, advancement in the drug development is needed. In this study, we explored whether apelin receptor (APJ) can become a candidate target. We found that APJ is expressed only in endothelial cells of IH (HemECs) but not in other vascular anomalies, and its antagonist, ML221, can negatively regulate cellular viability and functions of HemECs. This inhibitory effect could be replicated in a murine hemangioma model. Importantly, in vitro experiments also indicated that ML221 failed to affect the proliferation or angiogenesis of normal endothelial cells or APJ-knockout HemECs. Through analysis of the phosphoantibody microarray data, ML221 was revealed to have an inhibitory effect on HemECs by suppressing the activation of mitogen-activated protein kinase/extracellular signal-regulated kinase pathway. These results verified the distinctive expression of APJ in IH and specific inhibition of HemEC activity caused by ML221. In addition, APJ was also detected in propranolol-resistant IH. Collectively, we propose that APJ can act as a specific marker and a promising therapeutic target for IH, which will facilitate further drug development.

Case report: Deterioration of infantile hemangioma related to oral or nebulized administration of β2-AR agonist: Three cases reports

Infantile hemangioma (IH) is a benign vascular tumor, characterized by a unique sequence of non-linear growth and spontaneous involution. Some hemangiomas require intensive treatment to avoid functional and aesthetic insufficiency. Although β-adrenergic receptor (β-AR) antagonists have been increasingly used as the first-line treatment since 2008, the IH rebound still exists with uncertain mechanism. Here, we report three cases of abrupt IH deteriorations that are mainly related to β2-AR agonist administration. Potential IH proliferation induced by β2-AR agonists, especially from oral or nebulized approaches, should be recognized more widely by healthcare providers. Additionally, it is necessary to carry out large sample studies to analyze the influence of β2-AR agonist administration on the deterioration of IH.

Quality of life improving after propranolol treatment in patients with Infantile Hemangiomas

Infantile hemangiomas may affect the quality of life (QoL) of patients and their family members, as anxiety and worry may commonly occur in parents, also linked to the social adversion they experience. We underline the beneficial impact of oral propranolol therapy on QoL of patients with infantile hemangiomas (IH) and of their relatives. A specific questionnaire measuring QoL was administered to parents of IH patients at beginning and end of a treatment with oral propranolol. Different aspects were investigated: site of the lesion, age of patients at starting therapy, length of treatment, occurrence of adverse effects and persistence/recurrence of the vascular anomaly. In all cases the questionnaire revealed a significant improvement of QoL, which was independent from all analyzed factors. It showed that oral propranolol administration in these patients combines optimal clinical results with relevant improvement of QoL, especially in cases of early management. The improvement of QoL seems unrelated to site of lesion, timing and duration of therapy, occurrence of drug-related adverse effects and persistence/recurrence of disease.

Non-β-blocker enantiomers of propranolol and atenolol inhibit vasculogenesis in infantile hemangioma

Propranolol and atenolol, current therapies for problematic infantile hemangioma (IH), are composed of R(+) and S(–) enantiomers: the R(+) enantiomer is largely devoid of beta blocker activity. We investigated the effect of R(+) enantiomers of propranolol and atenolol on the formation of IH-like blood vessels from hemangioma stem cells (HemSCs) in a murine xenograft model. Both R(+) enantiomers inhibited HemSC vessel formation in vivo. In vitro, similar to R(+) propranolol, both atenolol and its R(+) enantiomer inhibited HemSC to endothelial cell differentiation. As our previous work implicated the transcription factor sex-determining region Y (SRY) box transcription factor 18 (SOX18) in propranolol-mediated inhibition of HemSC to endothelial differentiation, we tested in parallel a known SOX18 small-molecule inhibitor (Sm4) and show that this compound inhibited HemSC vessel formation in vivo with efficacy similar to that seen with the R(+) enantiomers. We next examined how R(+) propranolol alters SOX18 transcriptional activity. Using a suite of biochemical, biophysical, and quantitative molecular imaging assays, we show that R(+) propranolol directly interfered with SOX18 target gene trans-activation, disrupted SOX18-chromatin binding dynamics, and reduced SOX18 dimer formation. We propose that the R(+) enantiomers of widely used beta blockers could be repurposed to increase the efficiency of current IH treatment and lower adverse associated side effects.

Systemic, local, and sclerotherapy drugs: What do we know about drug prescribing in vascular anomalies?

Off-label drug prescribing, frequent in the treatment of vascular anomalies (VA), relies on the quality of the literature reporting drug efficacy and safety. Our objective is to review the level of evidence (LOE) surrounding drug use in VA, which is more prevalent in pediatric care. A list of drugs used in VA was created with a literature review in July 2020. For each drug listed, the article displaying the highest LOE was determined and then compared between efficacy/safety data, routes of administration, pharmacological categories and a subset of VA. The influence of research quality on study results was also explored. The median LOE for the 74 drugs identified poor methodological quality, with a predominance of retrospective studies or case reports. Drug safety is currently inadequately reported. This is alarming as many treatments display significant safety concerns. Also, current literature displays major publication bias that probably leads to overestimation of drug efficacy in VA.

Treatment patterns and outcomes in children with infantile hemangiomas: A retrospective observational analysis

OBJECTIVE

This study aimed to make use of real-world medical records to explore the clinical characteristics, treatments, and outcomes of infantile hemangiomas in southeastern China.

METHODS

This study applied a retrospective observational method using real-world data derived from the electronic medical records of the Foshan Women and Children Hospital, southeastern China dated between June 2014 and June 2019.

RESULTS

A total of 2427 patients with infantile hemangiomas were recruited in this study, including 942 (38.8%) males and 1485 (61.2%) females. Among the participants, 620 (25.5%) were high-risk infantile hemangioma, 449 (18.5%) were medium risk, and 1358 (56.0%) were low risk. A total of 14 treatment patterns in clinical practice were identified. The top 3 treatment patterns in each group of risk levels were the same: laser therapy, a combination of laser therapy and topical timolol maleate, and topical timolol maleate. The outcomes of the top 3 treatment patterns were significantly (P < 0.05) different in each risk group.

CONCLUSION

Among the top 3 treatment patterns, laser therapy or a combination of laser therapy and topical timolol maleate were more likely to have an "Excellent" outcome.

The effectiveness of oral propranolol for infantile hemangioma on the head and neck region: A case series

Introduction

Infantile hemangioma is the most common tumor in infancy, with 60% occurring on the face and neck. A large tumor involving the facial region will cause significant aesthetic and functional impairment and isn't always easy to treat surgically. A non-invasive treatment is needed for this condition. Propranolol has recently been used as a choice of treatment in infantile hemangioma.

Presentation of case

We presented two cases of large problematic infantile hemangioma that were successfully managed with oral propranolol.

Discussion

Large problematic lesions that ulcerate and bleed often need surgery; however, a substantial defect resulting from surgery is tricky to reconstruct and can cause significant scar. Propranolol is used because of its efficacy and low risk characteristics.

Conclusion

Propranolol is an effective treatment to reduce the need of surgical intervention in problematic hemangioma.

•

Hemangioma is the most common tumor in infancy, grows rapidly, slowly regress, and never recur

•

Not all hemangioma with ulceration and bleeding are good candidates for surgery due to the large defect it may produce

•

Propanolol is an effective alternative treatment before surgery in problematic hemangioma, especially if given during proliferative phase

Propranolol vs. steroids in the treatment of infantile hemangiomas: A meta-analysis

Infantile hemangioma (IH) is a common disease, and drug therapy is the most common treatment method. Clinically, steroids have long been used as first-line drugs, but in recent years, some doctors have begun to use propranolol to treat infantile hemangiomas (IHs). The present study performed a meta-analysis to evaluate the clinical effects of propranolol in comparison with steroids in the treatment of infantile hemangiomas. A detailed review of the literature on PubMed, Cochrane Library, Embase and Web of Science was performed prior to March 31, 2020. All literatures were compared with the clinical effects of propranolol and steroids in the treatment of infantile hemangiomas. A total of two researchers independently screened the literature according to the selection criteria, extracted data and assessed the risk of bias for the included studies. Review Manager 5.3 was used to meta-analyze all the included studies. According to the selection criteria, nine articles were included in the present study. The meta-analysis revealed that the effective rate of propranolol was greater than that of steroids in treating infantile hemangiomas [odds ratio (OR), 3.96, 95% confidence interval (CI), 2.47-6.37; P<0.00001]. Additionally, propranolol had fewer complications than steroids (OR, 0.21; 95% CI, 0.12-0.36; P<0.00001). The recurrence rate of the two groups was not statistically different (OR, 1.83; 95% CI, 0.59-5.70; P=0.3) and the surgical resection rate of propranolol was lower than steroids (OR, 0.19; 95% CI, 0.08-0.46; P=0.0002). The present study demonstrated that propranolol is more effective than steroids for the treatment of IHs, and provides a theoretical basis for the clinical use of propranolol as an alternative to steroids.

Paediatrics: how to manage infantile haemangioma

Infantile haemangiomas (IHs) are relatively common benign vascular tumours found in the paediatric population. They have varying sizes and involve different depths in the skin leading to various colours, shapes and textures. Although considered harmless in most cases, they may lead to life-threatening complications or cause permanent disfigurations and organ dysfunction. For problematic IHs, the treatment options include oral and topical beta-blockers, systemic corticosteroids, laser treatment, and surgery. In this narrative review, the treatment options for problematic IH are compared and delivered concisely to facilitate the clinical decisions from practitioners, including those in primary care settings. Oral propranolol is currently considered the first-line intervention for problematic IHs. For superficial lesions, there is robust evidence for the use of topical timolol maleate. Systemic corticosteroids are sometimes used in specific situations such as resistance or contraindications to beta-blockers. Surgical excision can be considered in cases requiring urgent intervention such as airway obstruction; this can be done alongside laser therapies for the removal of residual tissue or when reconstructing areas of deformity. The combination of multiple treatment modalities may lead to a more rapid clinical response.

Beta-blocker-associated hypoglycaemia: New insights from a real-world pharmacovigilance study

AIMS

To investigate the statistical association between hypoglycaemia and β-blocker use and to define what patient and drug characteristics could potentially increase the risk for its occurrence.

METHODS

We investigated the relationship between pharmacological parameters of β-blockers and the occurrence of hypoglycaemia by conducting a case/non case analysis using the Food and Drug Administration Adverse Event Reporting System database. Pharmacological properties that could represent a predictive factor for hypoglycaemia were analysed through a multilinear binary logistic regression (null hypothesis rejected for values of P < .05). We also performed a systematic review of clinical studies on this association.

RESULTS

Of 83 954 selected reports, 1465 cases (1.75%) of hypoglycaemia were identified. The association was found statistically significant for nadolol (reporting odds ratio [95% confidence interval]: 6.98 [5.40-9.03]), celiprolol (2.35 [1.35-4.10]), propranolol (2.14 [1.87-2.46]) and bisoprolol (1.42 [1.25-1.61]). Paediatric cases (n = 310) showed a positive association with hypoglycaemia for long half-life drugs (odds ratio [95% confidence interval]: 2.232 [1.398-3.563]) and a negative association for β1-selectivity (0.644 [0.414-0.999]). Seven papers were included in the systematic review. Because of great heterogeneity in study design and demographics, hypoglycaemia incidence rates varied greatly among studies, occurring in 1.73% of the cases for propranolol treatment (n total participants = 575), 6.6% for atenolol (n = 30) and 10% for carvedilol (n = 20).

CONCLUSION

Nadolol appears to be the β-blocker significantly most associated with hypoglycaemia and children represent the most susceptible sample. Furthermore, long half-life and nonselective β-blockers seem to increase the risk for its occurrence.

Japanese clinical practice guidelines for vascular anomalies 2017

The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine (EBM) techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of September 2014 was searched in Pubmed, Cochrane Library, and Japana Centra Revuo Medicina (JCRM). The strengths of evidence and recommendations acquired by systematic reviews were determined following the Medical Information Network Distribution System (MINDS) technique. A total of 33 CQs were used to compile recommendations and the subjects included efficacy of resection, sclerotherapy/embolization, drug therapy, laser therapy, radiotherapy, and other conservative treatment, differences in appropriate treatment due to the location of lesions and among symptoms, appropriate timing of treatment and tests, and pathological diagnosis deciding the diagnosis. Thus, the Japanese Clinical Practice Guidelines for Vascular Anomalies 2017 have been prepared as the evidence-based guidelines for the management of vascular anomalies.

Treatments for infantile Hemangioma: A systematic review and network meta-analysis

BACKGROUND

Infantile hemangioma (IH) is common in children, which may bring about cosmetically disfiguring, functional impairment, and exhibiting complications. There had been various therapies and we aimed to assess the efficacy and adverse effects of different therapies through network meta-analysis.

METHODS

We searched PubMed, Embase, Cochrane Library and Web of Science (from database inception to April 11, 2020) for studies assessing the efficacy, success rate and adverse effects. Direct pairwise comparison and a network meta-analysis under random effects were performed. We also assessed the ranking probability.

FINDINGS

A total of 30 randomized clinical trials with more than 20 different therapeutic regimens were identified. Treatment combined propranolol orally with laser could improve the curative effect than monotherapy. Laser with topical β blockers showed more efficiency than others whether in children under 6 months or not. The long-pulsed dye laser might be the best laser therapy. A higher dose and a longer treatment duration of propranolol orally achieved a higher success rate and increased side effects. Plus pulse dye laser with propranolol had the lowest incidence of adverse reactions, such as ulcer, color sink and color reduction.

INTERPRETATION

A combination of β blockers and laser might be the first-line treatment of IHs and a longer pulsed dye laser is preferred.

FUNDING

No funding was received.

The efficacy and safety of treatments for infantile hemangiomas: a Bayesian network meta-analysis

Whether infantile hemangiomas (IHs) need to be treated and which treatment should be preferred are still controversial. We aimed to compare and rank the treatments and identify the optimal treatment for IHs. We searched PubMed, EMBASE, the Cochrane Library, Web of Science, and other sources for randomized controlled trials up to August 2019. We included trials comparingdifferent treatments and reported response or adverse events rate in IH patients. Two reviewers independently evaluated studies by specific criteria and extracted data. We assessed the risk of bias with the Cochrane risk of bias tool. Random-effects were performed for pair-to-pair and Bayesian framework network meta-analyses. The primary outcomes were efficacy and safety. We deemed 20 studies eligible, including 1149 participants and eight interventions. For efficacy, oral propranolol and topical propranolol/timolol were better than observation/placebo (OR, 95% CrI: 17.05, 4.02-94.94; 9.72, 1.91-59.08). For safety, topical propranolol/timolol was significantly better tolerated than oral propranolol (0.05, 0.001-0.66). Cluster analysis demonstrated oral propranolol was the most effective treatment for IHs, while topical propranolol/timolol showed high efficacy and the highest safety. Laser, intralesional propranolol or glucocorticoid, oral glucocorticoid, or captopril had significantly lower priority than oral propranolol or topical propranolol/timolol considering both efficacy and safety. The quality of evidence was rated as moderate or low in most comparisons. This network meta-analysis found topical beta-blockers had the potential to be the most preferable and beneficial option for IHs in consideration of both efficacy and safety.

Efficacy and adverse effects of oral propranolol in infantile hemangioma: a meta-analysis of comparative studies

BACKGROUND

A number of clinical trials evaluated the efficacy and adverse effects of oral propranolol in the treatment of infantile hemangioma (IH), but the treatment has not yet been standardized. This meta-analysis aims to reevaluate the efficacy and adverse effects of oral propranolol in comparative studies and to provide a reliable basis for clinical administration in the therapy for IH.

METHODS

Data were obtained from PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure and Wanfang database, from inception to December 1st, 2018. The pooled risk ratios (RR) with 95% confidence intervals (95% CI) were calculated and used to evaluate the effect size. The meta-analysis was performed using the random-effects model due to heterogeneity between the studies. The Cochrane Collaboration 6 aspects of bias, methodological index for non-randomized studies and the Newcastle-Ottawa Scale were used to assess the risk for bias. Sensitivity analysis, publication bias and subgroup analysis were performed.

RESULTS

Eighteen unique studies involving 2701 unique children were included in the analysis. The response rate was reported in 18 trials, which compared oral propranolol with other treatments. The heterogeneity was statistically significant (P < 0.00001, I² = 95%). The difference in the response rate was statistically significant (RR = 1.40, 95% CI 1.13-1.75) while compared with the controls. However, no significant difference in the adverse events rate (RR = 0.78, 95% CI 0.45-1.34) and relapse rate (RR = 1.45, 95% CI 0.66-3.16) were found. Otherwise, the subgroup analysis indicated that the RR was 1.64 (95% CI 0.24-11.36) for low-dose propranolol (1 mg/kg/day), 1.42 (95% CI 1.12-1.80) for medium dose (2 mg/kg/day) and 1.46 (95% CI 1.17-1.82) for high dose (3 mg/kg/day), but the high dose had higher adverse events rate than medium dose, with 3.60% and 86.22%, respectively. The effectiveness of propranolol therapy among cases of treatment duration less than 6 months (RR = 1.24, 95% CI 1.05-1.47) was inferior to that of treatment duration greater than or equal to 6 months (RR = 1.46, 95% CI 1.11-1.92).

CONCLUSIONS

This meta-analysis reveals that oral propranolol is superior to other treatments in improving response rate of IH and can be used as the first-line therapy for IH children. A dosage of 2 mg/kg/day propranolol orally may be a good choice for IH. However, further studies are essential.

Surgical resection of infantile hemangiomas following medical treatment with propranolol versus corticosteroids

PURPOSE

There has been a paradigm shift from corticosteroid to propranolol treatment for infantile hemangiomas (IHs), with surgical resection reserved for complicated or persistent IHs. The purpose of this study was to determine if propranolol treatment was associated with decreased utilization of surgical resection compared to corticosteroids.

METHODS

A single center retrospective chart review of all corticosteroid or propranolol treated IHs between 2005 and 2014 was performed. Demographic and clinical data were collected. Both univariate and multivariate analyses were performed with the primary outcome of requiring surgical intervention.

RESULTS

Of 652 patients with IH, 52 were treated with oral corticosteroids and 195 with propranolol only. Surgical intervention was required in 14 (27%) of steroid patients vs 18 (9%) of propranolol patients (p < .001). On multivariable analysis patients treated with steroids had 3.3 the odds of requiring surgery when compared to propranolol patients (p = .001). Prematurity (<37 weeks) was also associated with increased odds of surgery (OR = 2.8, p = .003).

CONCLUSION

Patients treated with propranolol required significantly fewer surgical interventions than those treated with corticosteroids suggesting a more efficacious treatment paradigm. Prematurity increases the need for surgical intervention regardless of the modality of medical treatment.

LEVEL OF EVIDENCE

Level III, treatment study.

Central Nervous System Effects of Oral Propranolol for Infantile Hemangioma: A Systematic Review and Meta-Analysis

Concerns about the effects of propranolol on the central nervous system (CNS) in the infantile hemangioma (IH) population have been raised. We conducted a meta-analysis of the CNS and sleep-related effects of oral propranolol in IH patients. PubMed, Embase, Cochrance, Web of Science, and Clinicaltrials.gov were searched for relevant studies. We included clinical trials that compared oral propranolol with other treatments among IH patients under 6 years old and monitored and reported any adverse events. Study characteristics, types and number of adverse events were abstracted. Cochrane Collaboration Risk of Bias Tool was used to assess risk of bias. Our main outcomes were CNS and sleep-related effects. Random-effects models were used to estimate the pooled risk ratio. We did not observe statistically significant associations between oral propranolol and CNS or sleep-related effects. Oral propranolol appeared to have a safer profile of CNS effects than corticosteroids (RR = 0.27, 95% CI 0.02⁻3.00), but had an increased risk versus non-corticosteroids (for CNS effect, RR = 1.40, 95% CI 0.86⁻2.27; for sleep-related effects, RR = 1.63, 95% CI 0.88⁻3.03). Despite no statistically significant associations, there were suggestive findings of increased CNS effects and sleep-related risk of propranolol versus non-corticosteroids. In practice, CNS and sleep-related events should be monitored more closely among IH patients treated with oral propranolol.

Interventions for infantile haemangiomas of the skin: abridged Cochrane systematic review and GRADE assessments

BACKGROUND

Infantile haemangiomas (IH) are soft swellings of the skin that occur in 3-10% of infants. When haemangiomas occur in high-risk areas or when complications develop, active intervention is necessary.

OBJECTIVE

To update a Cochrane Review assessing the interventions for the management of IH in children.

METHODS

We searched for randomized controlled trials in CENTRAL, MEDLINE, Embase, LILACS, AMED, PsycINFO, CINAHL and six trials registers up to February 2017. We included 28 trials (1728 participants) assessing 12 interventions.

RESULTS

We downgraded evidence from high to moderate/low for issues related to risk of bias and imprecision. Oral propranolol (3 mg kg^-1 daily) probably improves clinician-assessed clearance vs placebo [risk ratio (RR) 16·61, 95% confidence interval (CI) 4·22-65·34; moderate quality of evidence (QoE)]; we found no evidence of a difference in terms of serious adverse events (RR 1·05, 95% CI 0·33-3·39; low QoE). We found the chance of reduction of redness may be improved with topical timolol maleate (0·5% gel applied twice daily) when compared with placebo (RR 8·11, 95% CI 1·09-60·09; low QoE). We found no instances of bradycardia or hypotension for this comparison.

CONCLUSIONS

Our key results indicate that oral propranolol and topical timolol maleate are more beneficial than placebo in terms of clearance or other measures of resolution, or both, without an increase in harm.

Effect of dosing regimen and microneedle pretreatment on in vitro skin retention of topically applied beta-blockers

Topical beta-blocker formulations are commonly used to treat infantile hemangiomas (IHs); however, the skin concentrations and drug permeation through the skin have not been quantified. Microneedles (MNs) may increase local skin concentrations, which could further enhance lesion clearance and improve dosing regimens. The objective of this study was to quantify skin concentrations and drug permeation of two beta-blockers, propranolol and timolol, in vitro after application to intact skin and skin pretreated with solid MNs of two lengths. Propranolol skin concentrations and drug permeation were significantly higher than timolol skin concentrations for all study conditions, which is likely due to the lipophilic nature of propranolol compared to the hydrophilicity of timolol. Propranolol skin concentrations were significantly influenced by dosing regimen, as skin concentrations increased with increasing drug application. Pretreatment of the skin with solid 250 μm and 500 μm length MNs increased local skin concentrations of timolol; propranolol skin concentrations did not significantly increase after MN pretreatment. Propranolol and timolol permeation through the skin increased after MN pretreatment with both MN lengths for both compounds. Taken together, solid MN pretreatment prior to application of topical timolol may be beneficial for deep or mixed IHs upon further optimization of the MN treatment paradigm.

Interventions for infantile haemangiomas of the skin

BACKGROUND

Infantile haemangiomas (previously known as strawberry birthmarks) are soft, raised swellings of the skin that occur in 3% to 10% of infants. These benign vascular tumours are usually uncomplicated and tend to regress spontaneously. However, when haemangiomas occur in high-risk areas, such as near the eyes, throat, or nose, impairing their function, or when complications develop, intervention may be necessary. This is an update of a Cochrane Review first published in 2011.

OBJECTIVES

To assess the effects of interventions for the management of infantile haemangiomas in children.

SEARCH METHODS

We updated our searches of the following databases to February 2017: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, AMED, LILACS, and CINAHL. We also searched five trials registries and checked the reference lists of included studies for further references to relevant trials.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of all types of interventions, versus placebo, active monitoring, or other interventions, in any child with single or multiple infantile haemangiomas (IHs) located on the skin.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. The primary outcome measures were clearance, a subjective measure of improvement, and adverse events. Secondary outcomes were other measures of resolution; proportion of parents or children who consider there is still a problem; aesthetic appearance; and requirement for surgical correction. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics.

MAIN RESULTS

We included 28 RCTs, with a total of 1728 participants, assessing 12 different interventions, including lasers, beta blockers (e.g. propranolol, timolol maleate), radiation therapy, and steroids. Comparators included placebo, an active monitoring approach, sham radiation, and interventions given alone or in combination.Studies were conducted in a number of countries, including China, Egypt, France, and Australia. Participant age ranged from 12 weeks to 13.4 years. Most studies (23/28) included a majority of females and different types of IHs. Duration of follow-up ranged from 7 days to 72 months.We considered most of the trials as at low risk of random sequence generation, attrition bias, and selective reporting bias. Domains such as allocation concealment and blinding were not clearly reported in general. We downgraded evidence for issues related to risk of bias and imprecision.We report results for the three most important comparisons, which we chose on the basis of current use. Outcome measurement of these comparisons was at 24 weeks' follow-up.Oral propranolol versus placeboCompared with placebo, oral propranolol 3 mg/kg/day probably improves clinician-assessed clearance (risk ratio (RR) 16.61, 95% confidence interval (CI) 4.22 to 65.34; 1 study; 156 children; moderate-quality evidence) and probably leads to a clinician-assessed reduction in mean haemangioma volume of 45.9% (95% CI 11.60 to 80.20; 1 study; 40 children; moderate-quality evidence). We found no evidence of a difference in terms of short- or long-term serious adverse events (RR 1.05, 95% CI 0.33 to 3.39; 3 studies; 509 children; low-quality evidence), nor in terms of bronchospasm, hypoglycaemia, or serious cardiovascular adverse events. The results relating to clearance and resolution for this comparison were based on one industry-sponsored study.Topical timolol maleate versus placeboThe chance of reduction of redness, as a measure of clinician-assessed resolution, may be improved with topical timolol maleate 0.5% gel applied twice daily when compared with placebo (RR 8.11, 95% CI 1.09 to 60.09; 1 study; 41 children;low-quality evidence). Regarding short- or long-term serious cardiovascular events, we found no instances of bradycardia (slower than normal heart rate) or hypotension in either group (1 study; 41 children; low-quality evidence). No other safety data were assessed, and clearance was not measured.Oral propranolol versus topical timolol maleateWhen topical timolol maleate (0.5% eye drops applied twice daily) was compared with oral propranolol (via a tablet taken once per day, at a 1.0 mg/kg dose), there was no evidence of a difference in haemangioma size (as a measure of resolution) when measured by the proportion of patients with a clinician-assessed reduction of 50% or greater (RR 1.13, 95% CI 0.64 to 1.97; 1 study; 26 participants; low-quality evidence). Although there were more short- or long-term general adverse effects (such as severe diarrhoea, lethargy, and loss of appetite) in the oral propranolol group, there was no evidence of a difference between groups (RR 7.00, 95% CI 0.40 to 123.35; 1 study; 26 participants; very low-quality evidence). This comparison did not measure clearance.None of our key comparisons evaluated, at any follow-up, a subjective measure of improvement assessed by the parent or child; proportion of parents or children who consider there is still a problem; or physician-, child-, or parent-assessed aesthetic appearance.

AUTHORS' CONCLUSIONS

We found there to be a limited evidence base for the treatment of infantile haemangiomas: a large number of interventions and outcomes have not been assessed in RCTs.Our key results indicate that in the management of IH in children, oral propranolol and topical timolol maleate are more beneficial than placebo in terms of clearance or other measures of resolution, or both, without an increase in harms. We found no evidence of a difference between oral propranolol and topical timolol maleate with regard to reducing haemangioma size, but we are uncertain if there is a difference in safety. Oral propranolol is currently the standard treatment for this condition, and our review has not found evidence to challenge this. However, these results are based on moderate- to very low-quality evidence.The included studies were limited by small sample sizes and risk of bias in some domains. Future trials should blind personnel and participants; describe trials thoroughly in publications; and recruit a sufficient number of children to deduce meaningful results. Future trials should assess patient-reported outcomes, as well as objective outcomes of benefit, and should report adverse events comprehensively. Propranolol and timolol maleate require further assessment in RCTs of all types of IH, including those considered problematic, as do other lesser-used interventions and new interventions. All treatments should be compared against propranolol and timolol maleate, as beta blockers are approved as standard care.

Intralesional Bleomycin Injection for Propranolol-Resistant Hemangiomas

Propranolol has been the first-line treatment for alarming hemangiomas. However, some hemangiomas are propranolol-resistant. The authors reported 1 propranolol-resistant hemangioma which was treated with intralesional bleomycin injections. Sixteen months after 3 injections, the lesion still remained stable. Its potential mechanism was clarified by ultrasonic monitoring. Intralesional bleomycin injection can be considered an ideal option in treating propranolol-resistant hemangiomas.

Advances in the Medical Management of Vascular Anomalies

Vascular anomalies comprise a spectrum of diseases that are broadly classified as tumors and malformations. Diagnosis is often challenging, given a wide range of clinical presentations with overlapping signs and symptoms. Accurate diagnosis is critical to determine prognosis and to generate a management plan, which frequently involves multiple subspecialists during different phases of treatment. An updated classification system provides structure and clear, consistent terminology, allowing for improved diagnosis, provider communication, and collaboration. Historically, treatment of vascular anomalies was primarily surgical and medical therapies were limited or ineffective. Recent discoveries of pharmacologic agents effective in treating vascular anomalies have broadened our medical therapeutic options, limiting the need for unnecessary or high-risk procedures and improving patients' quality of life.

Vascular Anomalies: A Pediatric Surgeon's Perspective

Anomalies affecting the capillary and venous channels form the bulk of the spectrum of vascular anomalies. As per International Society for the Study of Vascular Anomalies (ISSVA) classification, these are referred to as hemangiomas and venous malformations respectively. The present article is a descriptive note of their management and outcomes. Retrospective records of patients over 17 y (January 2000 through December 2016) were reviewed for presentation, management and outcomes. Outcomes were graded into 3 subgroups based on subjective assessment of clinical images: Group A = near-total response (>90%); Group B = 50-90% and Group C = <50% reduction. Among 90 cases of hemangioma, majority were located in head and neck (86.7%). Outcomes recorded in children who received steroids (n = 36) were: Group A = 61.1%, B = 25% and C = 13.9%; steroids and beta-blockers (n = 8): Group A = 62.5%, B = 25% and C = 12.5%; only beta-blockers (n = 4): Group A = 75% and B = 25%; intralesional sclerotherapy (n = 32): Group A = 55.2% and B = 44.8%; steroids followed by sclerotherapy (n = 7): Group A = 28.6% and B = 71.4%; excision (n = 3): Group A = 100%. Among 171 cases of venous malformation, majority were located in head and neck (49.6%). Outcomes recorded in children who received sclerotherapy (n = 165) were Group A = 20.7%, B = 51% and C = 28.3%; steroids (n = 3): Group A = 100%; beta-blockers (n = 1): Group C = 100%; excision (n = 2): Group A = 100%. Better outcome was noted in smaller-sized lesions and those who required lesser volume of sodium tetradecyl sulfate (STS) injection. Thus, to conclude, the decision regarding the choice and timing of each therapeutic modality should be individualized based on location, size and type of the lesion. The goal of management in these lesions should be to improve the quality of life rather than elimination of the lesion.

Infantile haemangioma

With a prevalence of 4·5%, infantile haemangiomas are the most common benign tumours of infancy, arising in the first few weeks of life and exhibiting a characteristic sequence of growth and spontaneous involution. Most infantile haemangiomas do not require therapy. However, to identify at-risk haemangiomas, close follow-up is crucial in the first weeks of life; 80% of all haemangiomas reach their final size by 3 months of age. The main indications for treatment are life-threatening infantile haemangioma (causing heart failure or respiratory distress), tumours posing functional risks (eg, visual obstruction, amblyopia, or feeding difficulties), ulceration, and severe anatomic distortion, especially on the face. Oral propranolol is now the first-line treatment, which should be administered as early as possible to avoid potential complications. Haemangioma shrinkage is rapidly observed with oral propranolol, but a minimum of 6 months of therapy is recommended.

Comparison of Efficacy and Safety Between Propranolol and Steroid for Infantile Hemangioma: A Randomized Clinical Trial

Importance

There are limited data from randomized clinical trials comparing propranolol and steroid medication for treatment of infantile hemangioma (IH).

Objective

To determine the efficacy and safety of propranolol compared with steroid as a first-line treatment for IH.

Design, Setting, and Participants

This randomized clinical noninferiority trial tested the efficacy and safety of propranolol vs steroid treatment for IH at a single academic hospital. All participants were diagnosed with IH between June 2013 and October 2014, had normal heart function, and had not been previously treated for IH.

Interventions

The participants were randomly assigned to either the propranolol group or the steroid group. In the propranolol group, the patients were admitted, observed for adverse effects for 3 days after treatment initiation, and then released and treated as outpatients for 16 weeks (2 mg/kg/d). In the steroid group, the patients were seen as outpatients from the beginning and were also treated for 16 weeks (2 mg/kg/d).

Main Outcomes and Measures

The primary efficacy variable was the response to treatment at 16 weeks, which was evaluated by the hemangioma volume using magnetic resonance imaging before and at 16 weeks after treatment initiation. While comparing the effect of medication between the groups, we monitored the adverse effects of both drugs.

Results

A total of 34 patients (15 boys, 19 girls; mean age, 3.3 months; range, 0.3-8.2 months) were randomized to receive either propranolol or steroid treatment (17 in each treatment group). Guardians for 2 patients in the steroid group withdrew their consent, and 1 patient in the propranolol group did not complete the efficacy test. The intention-to-treat analysis, applying multiple imputations, found the treatment response rate in the propranolol group to be 95.65%, and that of the steroid group was 91.94%. Because the difference in response rate between the groups was 3.71%, propranolol was considered noninferior. We found that there was no difference between the groups in safety outcomes.

Conclusions and Relevance

Our trial demonstrated that propranolol was not inferior to steroid with respect to therapeutic effects in IH.

The changing face of complicated infantile hemangioma treatment

Infantile hemangiomas are the most common vascular tumors of infancy. A multidisciplinary approach including dermatologists, otolaryngologists, plastic surgeons, hematologists/oncologists and interventional/diagnostic radiologists is crucial for appropriate management of children with complicated infantile hemangiomas. Since its unforeseen discovery in 2008, propranolol has become the first-line treatment for infantile hemangiomas, eclipsing systemic corticosteroids and radiologic intervention. There are still, however, uncommon indications for more aggressive interventional management. We review the 2014-updated International Society for the Study of Vascular Anomalies (ISSVA) classification for vascular anomalies. Additionally, we suggest management algorithms for complicated lesions, including recommendations for radiologic and surgical intervention.

Safety of Oral Propranolol for the Treatment of Infantile Hemangioma: A Systematic Review

BACKGROUND AND OBJECTIVES

Given the widespread use of propranolol in infantile hemangioma (IH) it was considered essential to perform a systematic review of its safety. The objectives of this review were to evaluate the safety profile of oral propranolol in the treatment of IH.

METHODS

We searched Embase and Medline databases (2007-July 2014) and unpublished data from the manufacturer of Hemangiol/Hemangeol (marketed pediatric formulation of oral propranolol; Pierre Fabre Dermatologie, Lavaur, France). Selected studies included ≥10 patients treated with oral propranolol for IH and that either reported ≥1 adverse event or effect (AE) or planned to capture AEs. Data capture was standardized and extracted study design, demographic characteristics, IH characteristics, intervention, and safety outcomes. AEs were assigned a system organ class and preferred term.

RESULTS

A total of 83 of 398 identified literature records met the inclusion criteria, covering 3766 propranolol-treated patients. The manufacturer's data for 3 pooled clinical trials (435 propranolol-treated patients) and 1 Compassionate Use Program (1661 patients) were included. AE data were reported for 1945 of 5862 propranolol-treated patients. The most frequently reported AEs included a range of sleep disturbances, peripheral coldness, and agitation. The most serious AEs (atrioventricular block, bradycardia, hypotension, bronchospasm/bronchial hyperreactivity, and hypoglycemia-related seizures) were managed by decreasing doses or temporary/permanent discontinuation of propranolol. Limitations included the variety of included study designs; monitoring, collection, and reporting of AE data; small sample sizes for some articles; and the wide scope of review.

CONCLUSIONS

Oral propranolol is well tolerated if appropriate pretreatment assessments and within-treatment monitoring are performed to exclude patients with contraindications and to minimize serious side effects during treatment.

Topical Timolol Maleate Treatment of Infantile Hemangiomas

BACKGROUND

There has been a dramatic increase in the off-label use of ophthalmic timolol maleate, a β-blocker used for infantile hemangioma (IH) treatment as a topical counterpart to oral propranolol. Its safety and efficacy in a pediatric population with IH have not been evaluated in a large cohort. Our goal was to retrospectively assess timolol's effectiveness, discern characteristics associated with response, and document reported adverse events.

METHODS

A multicenter retrospective cohort study of 731 patients treated with topical timolol was completed at 9 centers. Inclusion required an IH suitable for timolol in the treating physician's judgment and access to clinical details including photographs. Logistic regression analysis and descriptive statistics were performed. Primary outcome measures were efficacy assessed by using visual analog scales for color and for size, extent, and volume from review of digital photographs taken as standard of care.

RESULTS

Most IHs were localized (80.1%) and superficial (55.3%). Risk of disfigurement was the most common indication for therapy (74.3%). Duration of therapy (P < .0001), initial thinness (P = .008), and subtype (P = .031) were significant predictors of response. Best response occurred in superficial IHs <1 mm thick. Fifty-three (7.3%) required subsequent therapy with systemic β-blocker. Adverse events were mild, occurring in 25 (3.4%) patients. No cardiovascular side effects were documented.

CONCLUSIONS

Timolol seems to be a well-tolerated, safe treatment option with moderate to good effectiveness, demonstrating best response in thin, superficial IHs regardless of pretreatment size. Timolol can be recommended as an alternative to systemic β-blockers and watchful waiting for many patients.

Evaluation of the efficacy and safety of topical timolol maleate combined with oral propranolol treatment for parotid mixed infantile hemangiomas

The aim of the present study was to assess the efficacy and safety of topical timolol maleate combined with oral propranolol for parotid infantile hemangiomas. Between October 2012 and April 2014, propranolol was administered orally at a dose of 1.0-1.5 mg/kg/day to 22 infants with proliferating hemangiomas in the Department of Oral and Maxillofacial Surgery (Hospital of Stomatology, China Medical University, Shenyang, Liaoning, China). A small amount of 0.5% timolol maleate eye drop solution was topically applied with medical cotton swabs to the area of the lesion twice a day, every 12 h. The study group consisted of 9 males and 13 females, aged 2-9 months, with a median age of 4.7 months. The lesions were all located in the parotid region, and measured between 3.5×4×0.5 and 7×8×3 cm in volume. The planned duration of therapy was 6-8 months, or the two drugs were stopped when complete regression of the lesions was obtained. The therapeutic outcomes and safety were assessed by the change in the size and color of the tumor, and the presence of adverse effects throughout the course of treatment. The mean duration of therapy was 21.1 weeks and ranged from 3 to 8 months. Of the 22 patients, 16 demonstrated an excellent response, 6 showed a good response and 2 displayed a moderate response. No major collateral effects were observed. Overall, oral propranolol combined with topical timolol maleate may be used as the first-line therapeutic choice in the treatment of infantile parotid mixed hemangioma.

Evidence-Based Medicine in the Treatment of Infantile Hemangiomas

Over the past decade, the treatment of infantile hemangiomas has undergone dramatic breakthroughs. This review critically evaluates the latest literature that supports the myriad treatment options for infantile hemangiomas. It chronicles the fading role of steroid therapy and evolution of propranolol use as the major treatment modality. Although propranolol is helping this disease become more of a medical disease and less of a surgical dilemma, the report also reveals a continued search to find nonsystemic treatment options. In summary, this is an evidence-based medicine review for the treatment of infantile hemangiomas.

Propranolol for infantile hemangioma: Current state of affairs

Infantile hemangioma (IH) is the most common benign tumor seen in infancy. This review provides up-to-date information on the pathophysiology, variations in clinical presentation, and natural history of IH, elaborating on associated anomalies, such as PHACE(S) syndrome and LUMBAR syndrome. Because of the benign and self-limiting characteristics seen in more than 90% of cases of IH, a conservative approach is usually chosen. However, some circumstances, such as ulceration, vision loss, breathing difficulties, or potential disfigurement, will require treatment during the proliferative phase. For decades, treatment of IH has primarily consisted of corticosteroids or surgery. Since 2008, propranolol has become the treatment of first choice. In this article, we bring to light the crucial changes in the treatment of IH over the past years. To date, there is still a lack of data on the possible long-term effects of propranolol treatment in young infants. A theoretical probability of the central nervous system being affected (that is, impairment of short- and long-term memory, psychomotor function, sleep quality, and mood) has recently been suggested. This review highlights research topics concerning these long-term adverse effects. Finally, information is provided on the potential instruments to measure IH severity and activity in clinical trials and/or in clinical practice and the recently developed and first-validated IH-specific quality-of-life questionnaire.

Pharmacologic Interventions for Infantile Hemangioma: A Meta-analysis

CONTEXT

Infantile hemangiomas (IH) may be associated with significant functional impact.

OBJECTIVE

The objective of this study was to meta-analyze studies of pharmacologic interventions for children with IH.

DATA SOURCES

Data sources were Medline and other databases from 1982 to June 2015.

STUDY SELECTION

Two reviewers assessed studies using predetermined inclusion criteria.

DATA EXTRACTION

One reviewer extracted data with review by a second.

RESULTS

We included 18 studies in a network meta-analysis assessing relative expected rates of IH clearance associated with β-blockers and steroids. Oral propranolol had the largest mean estimate of expected clearance (95%; 95% Bayesian credible interval [BCI]: 88%-99%) relative to oral corticosteroids (43%, 95% BCI: 21%-66%) and control (6%, 95% BCI: 1%-11%). Strength of evidence (SOE) was high for propranolol's effects on reducing lesion size compared with observation/placebo. Corticosteroids demonstrated moderate effectiveness at reducing size/volume (moderate SOE for improvement in IH). SOE was low for effects of topical timolol versus placebo.

LIMITATIONS

Methodologic limitations of available evidence may compromise SOE. Validity of meta-analytic estimates relies on the assumption of exchangeability among studies, conditional on effects of the intervention. Results rely on assumed lack of reporting bias.

CONCLUSIONS

Propranolol is effective at reducing IH size compared with placebo, observation, and other treatments including steroids in most studies. Corticosteroids demonstrate moderate effectiveness at reducing IH size/volume. The meta-analysis estimates provide a relative ranking of anticipated rates of lesion clearance among treatments. Families and clinicians making treatment decisions should also factor in elements such as lesion size, location, number, and type, and patient and family preferences.

Cardiovascular drugs in the treatment of infantile hemangioma

Since the introduction of propranolol in the treatment of complicated infantile hemangiomas (IH) in 2008, other different beta-blockers, including timolol, acetabutolol, nadolol and atenolol, have been successfully used for the same purpose. Various hypotheses including vasoconstriction, inhibition of angiogenesis and the induction of apoptosis in proliferating endothelial cells have been advanced as the potential beta-blocker-induced effect on the accelerated IH involution, although the exact mechanism of action of beta-blockers remains unknown. This has generated an extraordinary interest in IH research and has led to the discovery of the role of the renin-angiotensin system (RAS) in the biology of IH, providing a plausible explanation for the beta-blocker induced effect on IH involution and the development of new potential indications for RAS drugs such as angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers in the treatment of IH. This review is focused on the current use of cardiovascular drugs in the treatment of IH.

Propranolol: Effectiveness and Failure in Infantile Cutaneous Hemangiomas

Infantile hemangiomas (IHs) occur in early infancy and are considered to be one of the most frequent childhood tumors. Poor responsiveness to the treatment and complications are reported in about 10 % of patients. For years, the most common treatments for cutaneous and complicated IHs were corticosteroids, interferon-α, vincristine, laser therapy, or surgical intervention. More recently, treatment with propranolol has been reported with high success rates, both in the cutaneous and complicated form of IHs, and it is now considered to be the first-line treatment for IHs. Herein we report five cases of cutaneous IHs who presented at our unit between January 2011 and June 2012: in three of five patients, the lesion improved soon after the beginning of propranolol treatment; one case presented slow but complete resolution; and in one patient the treatment was unsuccessful. Patients who do not respond to propranolol have been seldom reported in the literature. However, the failure of propranolol treatment in childhood hemangiomas has been more frequent in our experience than that reported in previous case series. More attention should be given to the cases that poorly or negatively respond to treatment, and to the mechanisms underlying the failure to respond to treatment with propranolol.

Therapeutic superiority of combined propranolol with short steroids course over propranolol monotherapy in infantile hemangioma

Infantile hemangiomas are the most common benign childhood tumor that may have functional and/or cosmetic complications. We aimed to compare the clinical efficacy of propranolol alone and propranolol primed with systemic corticosteroids on the outcome of infantile hemangioma. A prospective randomized study included 40 infants aged less than 9 months with cutaneous hemangiomas. Patients were randomly assigned into two groups: group A were given oral prednisolone for the initial 2 weeks combined with oral propranolol, while group B were given oral propranolol alone for 6 months. The median age of the studied patients was 4.5 months (ranged 4 weeks-8 months). Sequential determination of the dimensions of the hemangiomas based on direct measurement and photographic analysis were performed. A significant reduction in the size of the lesions was found in group A in the 2-, 4-, and 8-week evaluation compared to group B (p < 0.001) with no statistical difference in the ultimate 6 month response (p = 0.134). Multiple logistic regression showed that early treatment before 6 months of age (OR 9.82, p = 0.007) and combined treatment with propranolol and prednisolone (OR 10.71, p = 0.006) were the predictors of best response.

CONCLUSION

Combining propranolol with corticosteroids gives a faster response and should be considered in treating life- or function-threatening hemangiomas.

Propranolol-responsive cranial nerve palsies in a patient with PHACES syndrome

PHACES syndrome is a neurocutaneous disorder characterized by the presence of segmental hemangiomas with associated anomalies of the posterior fossa, cerebral vasculature, cardiovascular system, eyes, and ventral or midline structures. We present the first case of propranolol-responsive congenital trigeminal and facial nerve palsies secondary to an intracranial hemangioma in a patient with PHACES syndrome.

Gastrointestinal Infantile Hemangioma: Presentation and Management

OBJECTIVES

The aim of the present study was to document the clinical presentation, diagnostic studies, and therapy of gastrointestinal infantile hemangiomas.

METHODS

This is a retrospective analysis of children with gastrointestinal hemangiomas culled from our Vascular Anomalies Center database. We detailed the location of visceral and cutaneous tumors, as well as radiologic and procedural methods used for diagnosis and treatment.

RESULTS

A total of 9 of the 16 children (14 girls and 2 boys) with hollow visceral hemangiomas also had cutaneous lesions. The most common extravisceral sites were regional facial lesions (n = 6), multifocal lesions (n = 2), and a solitary chest lesion (n = 1). Presenting symptoms were melena and hematochezia in the first 4 months of life (n = 14); several infants required multiple blood transfusions. The most frequent locations were small bowel and mesentery. One-half of the patients (n = 8) were diagnosed by laparotomy; the majority (n = 12) had suspicious radiologic findings. Corticosteroid and/or propranolol were the most common therapies.

CONCLUSIONS

Melena and hematochezia, sometimes with profound anemia, in the first 4 months of life, suggest the possibility of intestinal infantile hemangioma even in the absence of cutaneous tumor. Intestinal bleeding, particularly in association with a regional facial lesion, should initiate workup: ultrasonography, computed tomography, and magnetic resonance imaging display diagnostic features. First-line treatment is medical management; bowel resection may be necessary, particularly for perforation.

Treatment of infantile haemangiomas: recommendations of a European expert group

With a prevalence of 2.6-4.5 %, infantile haemangiomas (IH) represent the most common tumour of infancy. While the majority of IH does not require therapy and regresses spontaneously, about 10 % of IH exhibit complications such as obstruction, ulceration or disfigurement. With the advent of oral propranolol, many conventional treatment options have become obsolete. This paper summarizes current recommendations for management of complicated IH. These recommendations have been written by an expert group after a consensus process including bibliographic review, several drafts of synthesis, meetings with quantitative voting system and redaction of an approved final manuscript.

CONCLUSION

Oral propranolol is the first-line agent for the treatment of complicated IH.

WHAT IS KNOWN

• Infantile haemangiomas (IH) are the most common tumours of infancy. Within a very short period after its discovery and long before the publication of randomized controlled trials, propranolol has become the number one agent for the treatment of complicated IH. What is New: • We report IH treatment recommendations of an international, interdisciplinary team of experts, based on an up-to-date review of the literature.
