LUMBAR syndrome-OEIS complex overlap: A case series and review.

We present three new and six published infants with overlapping features of LUMBAR syndrome (lower body hemangioma, urogenital anomalies, spinal cord malformations, bony deformities, anorectal/arterial anomalies and renal anomalies) and OEIS complex (omphalocele, exstrophy, imperforate anus, and spinal defects), also known as cloacal exstrophy. OEIS is included under the recently proposed umbrella coined recurrent constellations of embryonic malformations (RCEMs). The RCEMs represent a phenotypically overlapping spectrum of rare disorders of caudal dysgenesis with unknown cause but likely shared pathogenesis. It has recently been proposed that LUMBAR be considered an RCEM. This report of infants with combined features of OEIS and LUMBAR is the first to demonstrate an overlap between LUMBAR and another RCEM, which supports LUMBAR's inclusion within the RCEM spectrum.

Pigmented purpuric dermatosis in children: a retrospective cohort with emphasis on treatment and outcomes.

BACKGROUND: Data regarding the course and treatment of pigmented purpuric dermatoses (PPD) in the paediatric population are limited. Although treatments for pigmented purpura are not well established, vitamin C and rutoside have been reported to be an effective treatment option and are widely utilized. OBJECTIVE: To assess the clinical course and utility of vitamin C and rutoside in paediatric patients with PPD treated at Ann & Robert H. Lurie Children's Hospital of Chicago between 2008 and 2018. METHODS: A retrospective review of all children with PPD managed at our hospital between 2008 and 2018 was performed. Additional follow-up was obtained via telephone interviews. RESULTS: A total of 101 patients met inclusion criteria. The female: male ratio was 1.3 : 1, and the median age at diagnosis was 8.8 years (IQR, 5.7-12.9). Median follow-up was 7.13 months (IQR, 3-17.4). The most common PPD subtypes were lichen aureus (43%) and Schamberg (34%). Fifty-three (52%) patients had evaluable follow-up documentation via their medical record or phone questionnaire. Twenty-eight patients were treated with vitamin C or rutoside or combination therapy. Twenty-five patients received no treatment. Clearance of the rash was noted in 24 (45.3%) patients overall, including 10 (42%) patients in the treated group and 14 (58%) patients in the untreated group. Recurrence was noted in seven (13.2%) patients. Treatment with vitamin C and/or rutoside was well tolerated without side effects. None of the patients were subsequently diagnosed with vasculitis, coagulopathy or cutaneous T-cell lymphoma. CONCLUSION: Pigmented purpuric dermatosis in children is a benign disorder with high rates of complete resolution. Treatment with vitamin C and rutoside is well tolerated, but in this cohort, there did not appear to be an advantage over watchful waiting without therapy.

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

PHACE (OMIM no. 606519) is a neurocutaneous syndrome that refers to the association of large, plaque-like, "segmental" hemangiomas of the face, with one or more of the following anomalies: posterior fossa brain malformations, arterial cerebrovascular anomalies, cardiovascular anomalies, eye anomalies, and ventral developmental defects, specifically sternal defects and/or supraumbilical raphe. The etiology and pathogenesis of PHACE is unknown, and potential risk factors for the syndrome have not been systematically studied. The purpose of this study was thus to determine (1) the incidence of PHACE and associated anomalies among a large cohort of hemangioma patients, (2) whether certain demographic, prenatal or perinatal risk factors predispose infants to this syndrome, and (3) whether the cutaneous distribution of the hemangioma can be correlated to the types of anomalies present. We undertook a prospective, cohort study of 1,096 children with hemangiomas, 25 of whom met criteria for PHACE. These 25 patients represented 20% of infants with segmental facial hemangiomas. Compared to previous reports, our PHACE patients had a higher incidence of cerebrovascular and cardiovascular anomalies. Two developed acute arterial ischemic stroke during infancy, while two with cardiovascular anomalies showed documented evidence of normalization, suggesting that both progressive and regressive vascular phenomena may occur in this syndrome. Correlation to the anatomic location of the hemangioma appears to be helpful in determining which structural abnormalities might be present. A comparison of demographic and perinatal data between our PHACE cases and the hemangioma cohort overall showed no major differences, except a trend for PHACE infants to be of slighter higher gestational age and born to slightly older mothers. Eighty-eight percent were female, a finding which has been noted in multiple other reports. Further research is needed to determine possible etiologies, optimal evaluation, and outcomes.

Oral corticosteroid use is effective for cutaneous hemangiomas: an evidence-based evaluation.

OBJECTIVES: To determine the efficacy of systemic corticosteroid therapy in treating enlarging, problematic cutaneous hemangiomas and to assess the relationship of dose to response and adverse effects. DESIGN: A quantitative systematic literature review was performed and inclusion and exclusion criteria were applied. SETTING: Patients were treated in primary care, referral centers, and institutional practices. Most patients were ambulatory, although some required hospitalization. PATIENTS: Inclusion criteria were original case series with a minimum of 5 patients with enlarging, problematic cutaneous hemangiomas treated with systemic corticosteroids. Exclusion criteria were being older than 2 years, receiving simultaneous other treatments, being lost to follow-up, or having insufficient information. Twenty-four original case series met inclusion criteria; 10 case series remained (184 patients) after exclusion criteria were applied. INTERVENTION: Patients were given a mean prednisone equivalent daily dose of 2.9 mg/kg (95% confidence interval [CI], 2.7-3.1 mg/kg) for a mean of 1.8 months (95% CI, 1.5-2.2 months). MAIN OUTCOME MEASURES: Response and rebound rates and dose-response and adverse effects-response relationships in responders vs nonresponders. RESULTS: Response was 84% (95% CI, 78%-89%; range, 60%-100%) and rebound was 36% (95% CI, 29%-44%; range, 0%-65%). A significant difference was found between the mean dose administered to responders vs nonresponders (P<.001). No significant difference was observed as to the occurrence of adverse effects (P =.3). CONCLUSION: Systemic corticosteroid treatment seems to be effective for problematic cutaneous hemangiomas of infancy.

Pigmented lesions in adolescents.

Accurate diagnosis of congenital and acquired pigmented lesions accompanied by an understanding of their natural history and disease associations is critical for the appropriate management and counseling of adolescents, as well as timely referral to specialists when indicated. The recognition of atypical nevi and other melanoma risk factors in adolescents should lead to institution of preventive measures, such as routine skin examinations and counseling regarding sun protection. Because the incidence of melanoma is increasing in adolescents as well as adults, prompt identification of suspicious melanocytic lesions may lead to early diagnosis and effective treatment of melanoma. Numerous pigmented lesions can also herald the presence of a multisystem disorder; the recognition of syndromes associated with these lesions should result in appropriate evaluation and genetic counseling of affected individuals. This review distinguishes pigmented lesions that histologically represent a proliferation of melanocytes and that may therefore confer an increased risk for melanoma, from pigmented lesions due to increased melanization alone (i.e., increased melanin content) that are not associated with malignancy.

Moles and melanoma.

The melanoma epidemic in adults is well documented, and there is now evidence that the incidence of malignant melanoma in teenagers is increasing. Risk factors for melanoma are recognizable in children and include congenital nevi, numerous common nevi, and atypical nevi. Large congenital nevi overlying the head or spine also carry risk for central nervous system involvement, which, if symptomatic, carries a grave prognosis. Laser therapy has recently been advocated for small congenital nevi but often yields only temporary improvement. Adjuvant therapy with interferon alfa-2b holds promise for patients with metastatic melanoma. Melanoma risk is also linked to sun sensitivity and childhood exposures, and sunscreen use has been promoted for prevention of skin cancer. Because many sunscreens offer protection from ultraviolet (UV) B but not UVA, spectra that may be involved in melanoma induction, pediatricians should counsel their families to practice a full program of sun protection that includes sun avoidance and protective clothing and eyeware in addition to sunscreens.
