Diagnosis and Management of Pediatric Psoriasis: An Overview for Pediatricians.

Pediatric psoriasis (PsO) and its associated comorbidities carry physical and psychosocial burdens in children and adolescents, which can negatively impact quality of life. However, features distinguishing pediatric PsO from eczema and other common inflammatory skin diseases may not be obvious to primary care providers, which may contribute to underrecognition and misdiagnosis. Accurate diagnosis of pediatric PsO is critical for managing the physical and psychological burdens associated with this disease. This review aims to support pediatricians with enough information to confidently diagnose pediatric PsO, assess associated physical and mental health comorbidities, and recommend first-line treatment options for children with mild to moderate PsO. To accomplish this, we provide information that distinguishes the appearance and symptoms of pediatric PsO from other common pediatric skin conditions. In addition, comorbidities and some of the mental health challenges associated with pediatric PsO are reviewed to help pediatricians provide appropriate care for patients in their clinical practice.

Do Antimicrobial Resistance Patterns Matter? An Algorithm for the Treatment of Patients With Impetigo.

BACKGROUND: Impetigo, a highly contagious bacterial skin infection commonly occurring in young children, but adults may also be affected. The superficial skin infection is mainly caused by Staphylococcus aureus (S. aureus) and less frequently by Streptococcus pyogenes (S. pyogenes). Antimicrobial resistance has become a worldwide concern and needs to be addressed when selecting treatment for impetigo patients. An evidence-based impetigo treatment algorithm was developed to address the treatment of impetigo for pediatric and adult populations. METHODS: An international panel of pediatric dermatologists, dermatologists, pediatricians, and pediatric infectious disease specialists employed a modified Delphi technique to develop the impetigo treatment algorithm. Treatment recommendations were evidence-based, taking into account antimicrobial stewardship and the increasing resistance to oral and topical antibiotics. RESULTS: The algorithm includes education and prevention of impetigo, diagnosis and classification, treatment measures, and follow-up and distinguishes between localized and widespread or epidemic outbreaks of impetigo. The panel adopted the definition of localized impetigo of fewer than ten lesions and smaller than 36 cm2 area affected in patients of two months and up with no compromised immune status. Resistance to oral and topical antibiotics prescribed for the treatment of impetigo such as mupirocin, retapamulin, fusidic acid, have been widely reported. CONCLUSIONS: When prescribing antibiotics, it is essential to know the local trends in antibiotic resistance. Ozenoxacin cream 1% is highly effective against S. pyogenes and S. aureus, including methycyllin-susceptible and resistant strains (MRSA), and may be a suitable option for localized impetigo.J Drugs Dermatol. 2021;20(2):134-142. doi:10.36849/JDD.5475 THIS ARTICLE HAD BEEN MADE AVAILABLE FREE OF CHARGE.

Treatment of Impetigo in the Pediatric Population: Consensus and Future Directions.

BACKGROUND: Impetigo is a common contagious superficial bacterial skin infection. Treatment of localized lesions can be achieved through topical antibiotics. Oral antibiotics are reserved for extensive disease. Increasing antimicrobial resistance to existing therapies have raised concerns. Antimicrobial stewardship, achieved through the responsible use of antibiotics, is an important measure to re-duce bacterial resistance. This review highlights treatment options for impetigo and shares consensus statements to help guide the management of impetigo in the pediatric population. OBJECTIVE: An expert panel of dermatologists and pediatricians convened in February 2019 to establish evidence-based consensus on the management of impetigo in the pediatric patient population. METHODS: The consensus was created in accordance with the Appraisal of Guidelines, Research and Evaluation (AGREE) II instrument. Prior to the consensus meeting, a systematic literature review was conducted, with the selected literature deemed clinically relevant to the consensus statements. Statements were further refined and assessed systematically following established standards. The consensus process consisted of a modified Delphi approach. The consensus was established through a minimal 75% “agree” rate. RESULTS: Thirteen consensus statements were developed addressing clinical challenges, existing treatment options and their limita-tions, and new therapeutic alternatives. CONCLUSION: Bacterial resistance to antimicrobials commonly used in treating impetigo has been reported. Antimicrobial stewardship is critical to optimize patient outcomes and to prevent the development of resistance. Healthcare providers should be aware of local resistance patterns in impetigo to help guide therapy. The use of newer safe and effective topical antibiotic alternatives as a first-line treatment should be an important step in antimicrobial stewardship.J Drugs Dermatol. 2020;19(3): doi:10.36849/JDD.2020.4679.

Intrascrotal sarcoidosis in a pediatric patient.

Sarcoidosis is a granulomatous disease with diverse skin manifestations and systemic involvement. We describe an adolescent boy who presented with unilateral scrotal swelling, constitutional symptoms, and a rash. Further workup demonstrated lymphadenopathy and pulmonary opacities. Granulomas caused by sarcoidosis were identified in biopsy specimens of the epididymis and skin lesions. No acid-fast organisms were found in biopsy specimens, and the patient had negative findings on placement of purified protein derivative (tuberculin). The concentration of angiotensin-converting enzyme was not elevated. We discuss pediatric sarcoidosis and, more specifically, intrascrotal sarcoidosis.

Topical tacrolimus in the treatment of inverse psoriasis in children.

Inverse psoriasis is a chronic disease frequently treated with topical corticosteroids. This retrospective case study evaluated the efficacy of tacrolimus 0.1% ointment to treat inverse psoriasis in children. Twelve of 13 patients had complete clearance of their psoriatic lesions within 2 weeks after initiating treatment with topical tacrolimus 0.1%.

Spectrum of phenotypic manifestations from a single point mutation of the p63 gene, including new cutaneous and immunologic findings.

Mutations in the p63 gene have been identified in five human disorders characterized by varying degrees of limb anomalies, ectodermal dysplasia, and facial clefts. We report a new point mutation in the p63 gene in a family in which the mother was initially diagnosed with Rapp-Hodgkin syndrome and her two offspring manifested ankyloblepharon, ectodermal defects, cleft lip and palate, syndrome. These three patients are the first to be reported with this particular mutation, which consists of a change from glycine to aspartic acid at position 506 on exon 14. The clinical spectrum observed in the three family members highlights the wide range of phenotypic variations that result from a single point mutation in the p63 gene. The mother lacks certain features classically associated with AEC, dermatitis of the scalp in particular. Severe erosive dermatitis of the scalp developed in both offspring, along with previously undescribed poikilodermatous skin changes and a deficiency of CD4 T lymphocytes. The new and varied phenotypic features noted in these patients emphasize the spectrum of disease caused by mutations in the p63 gene and raise the possibility of a role for it in maintaining immunocompetence.

Treatment of Nevus comedonicus with topical tazarotene and calcipotriene.

Nevus comedonicus is a rare developmental defect of the pilosebaceous unit. It is also thought to be a variant of epidermal nevus. Previously reported treatments include surgical excision, CO2 laser, dermabrasion, extraction, topical retinoic acid, and numerous topical keratolytics. We present a case of a 7-year-old boy with bilateral nevus comedonicus who experienced cosmetic improvement with topical tazarotene and calcipotriene cream. This combination represents a novel therapeutic approach to the treatment of this cutaneous abnormality.

Anterior encephalocele with subcutaneous right facial nodule.

Encephaloceles consist of heterotopic brain tissue that remains connected to the central nervous system. As such, these lesions can occur anywhere along the midline of the head, neck, and back. The clinical findings associated with an encephalocele are often cutaneous, prompting consultation with a dermatologist. Although abnormalities of the skin overlying the spinal cord are readily recognized by our specialty as markers for dysraphism, head and neck lesions may present a diagnostic challenge. We describe a case of an anterior encephalocele to increase awareness of this disorder and to emphasize the clinical findings that will assist with diagnosis. Our case is of particular interest because of the parasagittal location of the facial nodules and minimal actual midline involvement.
