RESUMEN

OBJECTIVE: To characterize long-term outcomes of PHACE syndrome. STUDY DESIGN: Multicenter study with cross-sectional interviews and chart review of individuals with definite PHACE syndrome ≥10 years of age. Data from charts were collected across multiple PHACE-related topics. Data not available in charts were collected from patients directly. Likert scales were used to assess the impact of specific findings. Patient-Reported Outcomes Measurement Information System (PROMIS) scales were used to assess quality of life domains. RESULTS: A total of 104/153 (68%) individuals contacted participated in the study at a median of 14 years of age (range 10-77 years). There were infantile hemangioma (IH) residua in 94.1%. Approximately one-half had received laser treatment for residual IH, and the majority (89.5%) of participants were satisfied or very satisfied with the appearance. Neurocognitive manifestations were common including headaches/migraines (72.1%), participant-reported learning differences (45.1%), and need for individualized education plans (39.4%). Cerebrovascular arteriopathy was present in 91.3%, with progression identified in 20/68 (29.4%) of those with available follow-up imaging reports. Among these, 6/68 (8.8%) developed moyamoya vasculopathy or progressive stenoocclusion, leading to isolated circulation at or above the level of the circle of Willis. Despite the prevalence of cerebrovascular arteriopathy, the proportion of those with ischemic stroke was low (2/104; 1.9%). PROMIS global health scores were lower than population norms by at least 1 SD. CONCLUSIONS: PHACE syndrome is associated with long-term, mild to severe morbidities including IH residua, headaches, learning differences, and progressive arteriopathy. Primary and specialty follow-up care is critical for PHACE patients into adulthood.

RESUMEN

We describe a case of congenital syphilis in an adopted infant with a unique dermatologic presentation of scalp granulomas, along with lymphadenopathy, anemia, and elevated liver transaminases. To our knowledge, this cutaneous morphology has not been previously reported in the literature. This case highlights the varied clinical presentation of congenital syphilis and the diagnostic challenge it poses for clinicians, especially in the context of unknown prenatal history/unknown risk factors, or if syphilis is acquired during pregnancy after routine screening is performed. As the incidence of congenital syphilis has more than tripled in recent years, this diagnosis should be considered when a neonate or infant presents with unexplained skin nodules.

RESUMEN

A 12-year-old boy presented with a 2-week history of persistent pruritic edematous plaques one day after he received the first dose of the BNT162b2 COVID-19 mRNA vaccine. A skin biopsy showed urticarial dermatitis with tissue eosinophilia consistent with a diagnosis of vaccine-associated eosinophilic cellulitis, with polyethylene glycol as a potential trigger.

RESUMEN

Bethlem myopathy is a collagen VI-related myopathy. Collagen VI is primarily not only associated with the extracellular matrix of skeletal muscle, but is also found in the skin, blood vessels, and other organs. Dermatologic findings described for Bethlem myopathy include follicular hyperkeratosis and abnormal scar formation, although clinical and histopathologic photographs remain elusive in the literature. We present a case of atypical keratosis pilaris-like follicular lesions in a patient with Bethlem myopathy and provide histopathologic correlation to better characterize the development of skin lesions in this rare neuromuscular disease.

RESUMEN

To date, there are no disease-specific instruments in Spanish to assess quality of life of patients with hidradenitis suppurativa. A multicentre study was previously carried out in Spain between 2016 and 2017 to develop the Hidradenitis Suppurativa Quality of Life-24 (HSQoL-24), a disease-specific questionnaire to assess quality of life in patients with hidradenitis suppurativa. The objectiv-es of this study are to revalidate the HSQoL-24 in Spanish with a larger sample of patients, and to present the English version. In this multi-centre study in Spain, patients with hidradenitis suppurativa completed the HSQoL-24, the Dermatology Life Quality Index and the Skindex-29. The Hurley staging system was used to assess the severity of the disease. Validation of the questionnaire was carried out in 130 patients, of whom 75 (57.7%) were women. This study demonstrates adequate values of reliability and validity of the HSQoL-24, confirming the previous test re-test validation and making this questionnaire one of wide clinical validity in terms of results perceiv-ed by patients.

RESUMEN

Thermoplastic masks made of polyester resin are used to immobilize patients receiving radiation therapy. We describe a case of allergic contact dermatitis (ACD) to a thermoplastic mask worn by a child receiving proton beam therapy for treatment of medulloblastoma. ACD to a thermoplastic mask in an adult was first reported in 2018. (J Med Case Rep. 2018;12:181) To our knowledge, ACD to a thermoplastic mask has not been reported previously in the pediatric population.

RESUMEN

We present what we believe to be the second case of pediatric penile porokeratosis and the youngest case reported. A 6-year-old boy presented with a pruritic, verrucous growth at the urethral meatus that recurred after two meatotomies. The diagnosis of porokeratosis was confirmed by biopsy. Porokeratosis should be added to the differential diagnosis of chronic hyperkeratotic penile lesions in children.

RESUMEN

Primary cutaneous aspergillosis is a rare but potentially life-threatening disease. We present the case of a premature infant who developed primary cutaneous aspergillosis with Aspergillus niger at the site of a skin abrasion that had been treated with a purple-colored cyanoacrylate product. The infection was treated successfully with gentle debridement of the cyanoacrylate product, followed by intravenous voriconazole and topical fluconazole. To our knowledge, this is the first reported case of primary cutaneous aspergillosis occurring at the site of cyanoacrylate-based skin adhesive.

RESUMEN

Orf is a zoonotic parapoxvirus typically transmitted to humans by a bite from goats or sheep. We present an unusual case of multiple orf lesions on the fingers of a 13-month-old child who was bitten by a goat and subsequently developed progressive swelling, blistering, and necrotic papulonodules of the hand followed by an additional diffuse, pruritic, papular rash. A primary diagnosis of orf infection was confirmed using real-time polymerase chain reaction, and the diffuse eruption was clinically consistent with an id reaction. Extensive necrosis and papular id reaction associated with orf rarely have been described.

RESUMEN

We present the case of a 7-day-old boy with significant, rapidly spreading blistering and desquamation in a "degloving" pattern on the hands that mimicked epidermolysis bullosa but was ultimately diagnosed as bullous impetigo caused by a clinically aggressive strain of Staphylococcus aureus. Bullous impetigo is a desquamating condition caused by local release of S. aureus exfoliative toxin A and is more commonly seen in children. This case highlights the fragility of newborn skin and reviews the major diagnoses that should be considered in an infant with significant blistering.

RESUMEN

Capillary malformation-arteriovenous malformation (CM-AVM) is an autosomal-dominant disorder, caused by heterozygous RASA1 mutations, and manifesting multifocal CMs and high risk for fast-flow lesions. A limited number of patients have been reported, raising the question of the phenotypic borders. We identified new patients with a clinical diagnosis of CM-AVM, and patients with overlapping phenotypes. RASA1 was screened in 261 index patients with: CM-AVM (n = 100), common CM(s) (port-wine stain; n = 100), Sturge-Weber syndrome (n = 37), or isolated AVM(s) (n = 24). Fifty-eight distinct RASA1 mutations (43 novel) were identified in 68 index patients with CM-AVM and none in patients with other phenotypes. A novel clinical feature was identified: cutaneous zones of numerous small white pale halos with a central red spot. An additional question addressed in this study was the "second-hit" hypothesis as a pathophysiological mechanism for CM-AVM. One tissue from a patient with a germline RASA1 mutation was available. The analysis of the tissue showed loss of the wild-type RASA1 allele. In conclusion, mutations in RASA1 underscore the specific CM-AVM phenotype and the clinical diagnosis is based on identifying the characteristic CMs. The high incidence of fast-flow lesions warrants careful clinical and radiologic examination, and regular follow-up.

RESUMEN

Acne vulgaris is a common inflammatory skin condition affecting most individuals at some point during their lives. Although acne is more commonly seen in adolescents, it can be seen in younger patients as well. It can be useful to classify pediatric acne based on the age of presentation as infantile, mid-childhood, or preadolescent. We describe a practical approach to the evaluation and treatment of acne in each of these age groups.

RESUMEN

Catalysts derived from Ni/Al/Mg/Ce hydrotalcite were prepared via a co-precipitation method, varying the Ce/Al atomic ratio. All of the catalytic systems thus prepared were tested for CO2 methanation under dark and photocatalytic conditions (visible and ultraviolet) under continuous flow with the light intensity set to 2.4 W cm-2. The substitution of Al by Ce formed a solid solution, generating oxygen vacancies and Ce3+/Ce4+ ions that helped shift the dissociation of CO2 towards the production of CH4, thus enhancing the activity of methanation, especially at lower temperatures (<523 K) and with visible light at temperatures where other catalysts were inactive. Additionally, for comparison purposes, Ni/Al2O3-based catalysts prepared via wetness impregnation were synthesized with different Ni loadings. Analytical techniques were used for the characterization of the systems. The best results in terms of activity were as follows: Hydrotalcite with Ce promoter > Hydrotalcite without Ce promoter > 25Ni/Al2O3 > 13Ni/Al2O3. Hydrotalcite, with a Ce/Al atomic ratio of 0.22 and a Ni content of 23 wt%, produced 7.74 mmol CH4 min-1·gcat at 473 K under visible light. Moreover, this catalyst exhibited stable photocatalytic activity during a 24 h reaction time with a CO2 conversion rate of 65% and CH4 selectivity of >98% at 523 K. This photocatalytic Sabatier enhancement achieved activity at lower temperatures than those reported in previous publications.

RESUMEN

Importance: A 2010 prospective study of 108 infants estimated the incidence of PHACE (posterior fossa malformations, hemangioma, arterial anomalies, cardiac defects, eye anomalies) syndrome to be 31% in children with facial infantile hemangiomas (IHs) of at least 22 cm2. There is little evidence regarding the associations among IH characteristics, demographic characteristics, and risk of PHACE syndrome. Objectives: To evaluate demographic characteristics and comorbidities in a large cohort of patients at risk for PHACE syndrome and assess the clinical features of large head and neck IH that may be associated with a greater risk of a diagnosis of PHACE syndrome. Design, Setting, and Participants: This multicenter, retrospective cohort study assessed all patients with a facial, head, and/or neck IH who were evaluated for PHACE syndrome from August 1, 2009, to December 31, 2014, at 13 pediatric dermatology referral centers across North America. Data analysis was performed from June 15, 2017, to February 29, 2020. Main Outcomes and Measures: The main outcome was presence or absence of PHACE syndrome. Data included age at diagnosis, sex, patterns of IH presentation (including size, segment location, and depth), diagnostic procedures and results, and type and number of associated anomalies. Results: A total of 238 patients (mean [SD] age, 2.96 [4.71] months; 184 [77.3%] female) were included in the analysis; 106 (44.5%) met the criteria for definite (n = 98) or possible (n = 8) PHACE syndrome. A stepwise linear regression model found that a surface area of 25 cm2 or greater (odds ratio [OR] 2.99; 95% CI, 1.49-6.02) and involvement of 3 or more locations (OR, 17.96; 95% CI, 6.10-52.85) to be statistically significant risk factors for PHACE syndrome. Involvement of the parotid gland (OR, 0.39; 95% CI, 0.18-0.85) and segment S2 (OR, 0.38; 95% CI, 0.16-0.91) was associated with a lower risk. Race and ethnicity may also be associated with PHACE syndrome risk, although more studies are needed. Conclusions and Relevance: This cohort study further described factors associated with both a higher and lower risk of PHACE syndrome. The presence of multiple anatomical sites and large surface area were associated with greater risk, whereas S2 or parotid IHs were associated with lower, but still potential, risk. These findings can help in counseling families and decision-making regarding evaluation of infants with large head and neck IHs.

RESUMEN

PURPOSE OF REVIEW: Acne vulgaris remains one of the most common conditions affecting adolescents. The pediatric practitioner is the first to evaluate adolescent acne, making familiarity with the condition and its management essential. This review covers some of the recent literature regarding acne to help practitioners stay current on the issues regarding this topic. RECENT FINDINGS: The pathogenesis of acne is multifactorial and complex, but recent advances in molecular genetics have provided additional information on the actions of Proprionibacterium acnes. Nutritional studies have reevaluated a possible role for diet and lifestyle factors in acne development. Many therapies are available to control acne and to limit associated scarring. Their appropriate use requires an understanding of not only the benefits but also the possible risks and adverse effects involved. Recent concerns regarding the use of antibiotics and isotretinoin will be addressed. SUMMARY: This study reviews the recent literature regarding teenage acne, focusing on pathogenesis, associations, and controversies and considerations in therapy.

RESUMEN

Using exploratory and confirmatory factor analyses, the aims were (a) to obtain, describe, and compare different solutions of three, five, and six first-order factors raised in the previous literature about the Children's Depression Inventory (CDI); (b) analyze the number and nature of the second-order factors; (c) test which model best reproduces the CDI structure; and (d) test possible developmental differences between child and adolescent samples. The CDI was applied to 4,707 Spanish children and adolescents with an age range between 7 and 16 years. Results show that best models considered five or six factors, including Social Problems (Anhedonia), Negative Affect, Externalizing, School Problems, and Negative Self-Esteem (Self-Deprecation). Also, a factor of Biological Dysregulation obtained some support. Higher-order factors do not reproduce the classical distinction between internalizing and externalizing symptoms. Finally, no large developmental differences in the CDI structure were found between children and adolescents samples.
