Frequency of the prominent transverse nasal root vein in children.

BACKGROUND: The presence of a vascular, blue linear discoloration on the nasal root of infants and young children is a frequent incidental feature, rarely reported in the medical literature. It is related to the trajectory of the transverse nasal root vein (TNRV). OBJECTIVE: To study the frequency and clinical characteristics of the vascular discoloration of the nasal root in children. METHODS: A prospective study was performed to address the presence or absence of vascular discoloration of the nasal root in all children under 6 years of age attending a pediatric dermatology clinic from November 2022 to November 2023. Data on age and skin phototype (Fitzpatrick classification I-VI) were also collected. RESULTS: Of 701 patients examined, 345 (49.2%) presented with a vascular discoloration of the nasal root. This was present in 97 of 193 (50.3%), 127 of 261 (48.7%), and 121 of 247 (49.0%) patients for the age groups 0-1, 1-3, and 3-6 years, respectively. The presence of vascular discoloration of the nasal root was more frequent in patients with lighter Fitzpatrick skin phototypes: 49 of 69 (71.0%) phototype II, 157 of 290 (54.1%) phototype III, and 137 of 337 (40.7%) phototype IV. CONCLUSIONS: A vascular discoloration of the nasal root is a frequent skin feature in infants and children, persisting at least until the age of 6. It does not constitute any medical problem aside from cosmetic concern and parents can be reassured of its benign nature. We propose the medical term "prominent TNRV" to describe this condition.

Transient infantile lingual leukoplakia: An underrecognized cause of white tongues in infancy.

We have observed a distinct phenomenon of transient oral lingual leukoplakia in infancy and report 22 healthy infants with gray-white plaques on the dorsal tongue with sparing of the tip from four medical centers in three countries. The onset of the eruption ranged from 1 week to 7 months of life and resolved in 19 patients (86%, with 3 patients lost to follow-up). None of the eight patients examined at 1 year of age had residual findings. We believe this is a common entity that can be distinguished from oral candidiasis on clinical and/or laboratory examination and name this entity "transient infantile lingual leukoplakia."

Atypical cutaneous findings of hand-foot-mouth disease in children: A systematic review.

INTRODUCTION: Hand-foot-mouth disease (HFMD) is a common childhood infectious disease. Atypical skin findings of HFMD, often associated with coxsackievirus A6 (CVA6), were first reported in 2008, with increasing reports worldwide since. Atypical lesions of HFMD often involve sites beyond the palms and soles and tend to have unusual, polymorphic morphology. METHODS: A systematic review was conducted on clinical features and outcomes of pediatric HFMD with atypical cutaneous manifestations. RESULTS: Eighty-five studies were included, representing 1359 cases with mean age 2.4 years and a male predominance of 61%. The most reported morphologies were vesicles (53%), papules (49%), and bullae (36%). Other morphologies included eczema herpeticum-like (19%), purpuric/petechial (7%), and Gianotti Crosti-like (4%). Common atypical sites included the arms and/or legs (47%), face (45%), and trunk (27%). CVA6 was identified in 63% of cases. Symptoms resolved in a mean of 10 days. Overall, 16% of cases received treatment, most commonly with acyclovir, intravenous antibiotics, or topical steroids. The most common complications were nail changes (21%) and desquamation (4%) which occurred a mean of 3 and 2 weeks after symptoms, respectively. CONCLUSION: Due to unusual morphologies resembling other conditions, HFMD with atypical cutaneous findings may be misdiagnosed, leading to inappropriate and unnecessary investigations, hospitalization, and treatment. Greater awareness of atypical presentations of HFMD is warranted to improve patient care and counseling on infection control precautions.

Treatment of ocular rosacea: a systematic review.

Rosacea is a common chronic skin disease distributed primarily around the central face. Ocular manifestations of rosacea are poorly studied, and estimates of prevalence vary widely, ranging from 6% to 72% in the rosacea population. Treatment options for ocular rosacea include lid hygiene, topical and oral antibiotics, cyclosporine ophthalmic emulsion, oral vitamin A derivatives, and intense pulsed light; however, a direct comparison of treatment methods for ocular rosacea is lacking. This review aims to compare treatment efficacy and adverse events for different treatment modalities in ocular rosacea. We performed a systematic review by searching Cochrane, MEDLINE and Embase. Title, abstract, full text screening, and data extraction were done in duplicate. Sixty-six articles met the inclusion criteria, representing a total of 1,275 patients. The most effective treatment modalities were topical antimicrobials and oral antibiotics, which achieved complete or partial response in 91% (n = 82/90) and 89% (n = 525/580) of patients respectively, followed by intense pulsed light (89%, n = 97/109 partial response), cyclosporine ophthalmic emulsion (87% n = 40/46), and lid hygiene (65%, n = 67/105). Combination treatments achieved a complete or partial response in 90% (n = 69/77). Results suggest that topical antimicrobials, oral antibiotics, intense pulsed light. and cyclosporine were the most efficacious single modality treatments.

Erythema nodosum associated with COVID19 infection: A pediatric case report and review of the literature.

Erythema nodosum (EN) is a common panniculitis characterized by tender erythematous nodules predominantly on the pretibial area and represents a hypersensitivity reaction to multiple triggers. COVID19 infection and vaccination have been associated with EN in the adult population. We report a pediatric case of EN following COVID19 infection and review the literature on COVID19 infection and COVID19 immunization-related EN.

Chilblain-Like Lesions (CLL) Coinciding With the SARS-CoV-2 Pandemic in Children: A Systematic Review.

Chilblain-like lesions (CLL) coinciding with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection have been described in the literature. Available reviews of the literature suggest that CLL are associated with younger age, an equal sex ratio, negative testing for SARS-CoV-2, and mild to no extracutaneous manifestations (ECM) associated with COVID-19 infection. This systematic review aims to provide a summary of reports of CLL associated with the early SARS-CoV-2 pandemic in children to clarify the prevalence, clinical characteristics, and resolution outcomes of these skin findings. Sixty-nine studies, published between May 2020 and January 2022, met inclusion criteria and were summarized in this review, representing 1,119 cases of CLL. Available data showed a slight male predominance (591/1002, 59%). Mean age was 13 years, ranging from 0 to 18 years. Most cases had no ECM (682/978, 70%). Overall, 70/507 (14%) of patients tested positive for COVID-19 using PCR and/or serology. In the majority the clinical course was benign with 355/415 (86%) of cases resolving, and 97/269 (36%) resolving without any treatment. This comprehensive summary of pediatric CLL suggests these lesions are rarely associated with COVID-19 symptoms or test positivity.

Bilateral harlequin syndrome, unilateral Horner syndrome, and Riga-Fede disease as presenting features of hereditary sensory and autonomic neuropathy type IV.

Hereditary sensory and autonomic neuropathy (HSAN) type IV, also known as congenital insensitivity to pain with anhidrosis (OMIM 256800), is part of a family of neurodegenerative disorders that manifest with variable sensory and autonomic neuropathies. In this report, we present a unique dermatological finding in a patient with HSAN type IV: bilateral harlequin syndrome that occurred in association with unilateral Horner syndrome, traumatic alopecia and Riga-Fede disease.

Adolescent with physiologic striae atrophicae of the thighs.

Physiologic striae atrophicae of adolescence occur mainly in healthy nonobese adolescents in association with the adolescent growth spurt. The striae typically present as erythematous, purple, or violaceous, horizontal linear plaques in the lumbar area. Occurrence of striae elsewhere on the body exclusively is rare. A PubMed search of the English literature using the key terms "physiological striae atrophicae of adolescence" OR "physiological striae atrophicae of puberty" AND "thigh" did not yield any prior report. We report a teenager with physiologic striae atrophicae of adolescence with striae restricted to the thighs.

Crisaborole 2% Ointment for Mild-to-Moderate Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic, relapsing, inflammatory condition marked by pruritus and traditionally treated with topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI). Crisaborole 2% ointment (a topical phosphodiesterase-4 inhibitor) is a newer topical agent for the treatment of AD. Crisaborole is indicated for treating mild-to-moderate AD and evidence from phase 3 and phase 4 trials show that crisaborole is an effective agent with a well-tolerated side effect profile for children >2 years of age. The most common side effects are pain and paresthesia at the application site. Treatments with tolerable safety profiles such as crisaborole may provide an alternative to patients with TCS phobia. The role of crisaborole in AD therapy may become clearer as multiple phase 4 trials are currently underway and their results are poised to answer more questions, including its safety profile for patients as young as 3 months of age, potential use as a steroid-sparing agent, and direct comparisons to TCS and TCI, which are the current mainstay treatments of mild-to-moderate AD.

An ulcerated giant segmental hemangioma resulting in contracture of the left elbow.

The majority of infantile hemangiomas are benign and will resolve on their own. We report a 4-month-old infant with an ulcerated giant segmental infantile hemangioma involving the left upper limb who developed a contracture of the left elbow despite treatment with oral propranolol, proper wound care, and regular intense physiotherapy. To our knowledge, contracture resulting from an infantile hemangioma has not been reported previously.

Approach to the Assessment and Management of Pediatric Patients With Atopic Dermatitis: A Consensus Document. Section III: Treatment Options for Pediatric Atopic Dermatitis.

Because atopic dermatitis (AD) is a chronic, relapsing disease, treatment requires the use of both active therapy to control flares and preventative maintenance therapy to promote integrity of the skin barrier. In this third of four sections, important clinical considerations for the treatment of pediatric AD are reviewed. Emerging therapies in development for pediatric AD are introduced.

Approach to the Assessment and Management of Pediatric Patients With Atopic Dermatitis: A Consensus Document. Section IV: Consensus Statements on the Assessment and Management of Pediatric Atopic Dermatitis.

This document is intended to provide practical guidance to physicians treating pediatric atopic dermatitis (AD), especially dermatologists, pediatricians, allergists, and other health-care professionals. The recommendations contained here were formalized based on a consensus of 12 Canadian pediatric dermatologists, dermatologists, pediatricians, and pediatric allergists with extensive experience managing AD in the pediatric population. A modified Delphi process was adopted with iterative voting on a 5-point Likert scale, with a prespecified agreement cutoff of 75%. Topic areas addressed in the 17 consensus statements reflect areas of practical management, including counselling, assessment, comorbidity management, and therapy.

Opportunistic fungal infection in children and management.

PURPOSE OF REVIEW: An opportunistic mycosis is a fungal agent of low pathogenicity that specifically infects immunocompromised hosts. Advances in transplantation, preterm care, immunosuppressive therapies and intensive care, have lead to the emergence of pediatric patients with serious immunodeficiency who are vulnerable to nonpathogenic fungi. RECENT FINDINGS: The advent of the use of biologic agents in pediatric disease as well as the advances in care of preterm and immunosuppressed patients opens up a new cohort of patients at risk of opportunistic mycotic infections. Recent cases of cutaneous histioplasmosis as the presenting sign of hyper-IgM syndrome and the case of cutaneous blastomycosis in a patient treated with infliximab underscore the need to have a high clinical suspicion for deep fungal infections in immunosuppressed patients. SUMMARY: The current review will focus on the cutaneous manifestations of cutaneous infections by Aspergillus, Blastomyces, histoplasmosis, and mucormycosis. Greater understanding of these diseases and high-quality research in identification and treatment can enhance care of patients in the coming future.

Unique presentation of transient zinc deficiency from low maternal breast milk zinc levels.

We report full-term siblings with a unique clinical presentation of polycyclic papulosquamous plaques secondary to transient zinc deficiency due to low maternal breast milk zinc levels. We present this case to highlight this unique presentation of zinc deficiency in breastfed infants.

Topical rapamycin (sirolimus) for the treatment of uncomplicated tufted angiomas in two children and review of the literature.

The mTOR inhibitor rapamycin is used systemically for the treatment of vascular lesions. We report the first use of topical rapamycin for the successful treatment of two cases of tufted angioma. The evidence for the use of topical rapamycin in other dermatologic conditions is summarized to aid in clinical decision making on preparations and anticipated side effects.
