Oral manifestations and dental approach in pediatric patient with lamellar congenital ichthyosis: 36-month follow-up

Introduction: Lamellar ichthyosis is an autosomal recessive congenital disease that causes dryness of the skin in the perioral region, which leads to pain during dental hygiene. Thus, the diet of patients with this disease tends to be pasty, which can lead to oral problems. Hyposalivation is suspected to be an oral manifestation of lamellar ichthyosis and may exert an influence on the incidence of carious lesions. Objective: Describe the treatment of a female patient diagnosed with lamellar ichthyosis who sought dental care initially when two years of age with complaints of dental pain, feeding difficulties and low weight. Case report: Atraumatic restorative treatment, extractions and topical application of fluoride varnish were performed in the patient, aesthetic of posterior installation of space, which also functioned as a rehabilitator. Conclusion: This study reinforces the need for the follow-up of the patient with LI by the dental surgeon since the birth of the first tooth, as dryness of the perioral skin and hyposalivation are conditions reported in individuals with lamellar ichthyosis. These conditions can affect oral hygiene and the frequency of carious lesions.

Introdução: A ictiose lamelar é uma doença congênita autossômica recessiva que causa ressecamento da pele na região peribucal, o que leva à dor durante a higiene dental, por isso a alimentação dos pacientes com essa doença tende a ser pastosa, podendo levar a problemas bucais. Suspeita-se que a hipossalivação possa ser uma manifestação oral da ictiose lamelar, podendo influenciar na incidência de lesões cariosas. Objetivo: Descrever o tratamento de uma paciente do sexo feminino, inicialmente com 2 anos de idade, diagnosticada com ictiose lamelar (IL), que procurou atendimento odontológico com queixa de dor dentária, dificuldade na alimentação e baixo peso. Relato do caso: Tratamento restaurador atraumático, exodontias e aplicação tópica de verniz fluoretado foram realizados na paciente, além de posterior instalação de mantenedor de espaço, o qual também funcionou como reabilitador estético. Conclusão: Este estudo reforça a necessidade do acompanhamento do paciente com IL pelo cirurgião dentista desde o nascimento do primeiro dente, pois secura da pele perioral e hipossalivação são condições relatadas em indivíduos com ictiose lamelar. Essas condições podem afetar a higiene bucal e a frequência de lesões cariosas.

Clinical and genetic analysis of a patient with autosomal recessive congenital ichthyosis due to compound heterozygous variants of ALOX12B gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical and genetic characteristics of a pediatric patient suspected for Autosomal Recessive Congenital Ichthyosis (ARCI).@*METHODS@#Clinical data of the patient was analyzed. Peripheral blood samples were collected from the patient and his parents for the extraction of genomic DNA. Next-generation sequencing (NGS) was then carried out. Candidate variants were confirmed by Sanger sequencing. A variety of bioinformatic tools including Mutation Taster, PROVEAN, and PolyPhen2 were used to predict the pathogenicity of the variants based on guidelines from the American College of Medical Genetics and Genomics (ACMG).@*RESULTS@#The patient, a 1-month-and-7-day-old male, had presented with cutaneous erythema and fine scaling of the whole body. NGS revealed that he has harbored compound heterozygous variants c.1579G>A (p.Val527Met) (paternal) and c.923T>C (p.Leu308Pro) (maternal) of the ALOX12B gene. The former was known to be likely pathogenic, while the latter was unreported previously and categorized as "likely pathogenic" based on the ACMG guidelines. Based on the clinical and genetic findings, the patient was diagnosed with ARCI.@*CONCLUSION@#The c.1579G>A and c.923T>C variants of the ALOX12B genes probably underlay the ARCI in this patient. Above finding has enriched the spectrum of ALOX12B mutations and enabled molecular diagnosis of the patient, based on which genetic counseling and prenatal diagnosis may be provided.

Novel Pathogenic Mutation of PNPLA1 Identified in Autosomal Recessive Congenital Ichthyosis: A Case Report / 中国医学科学杂志(英文版)

Autosomal recessive congenital ichthyosis (ARCI) is characterized by being born as collodion babies, hyperkeratosis, and skin scaling. We described a collodion baby at birth with mild ectropion, eclabium, and syndactyly. Whole exome sequencing showed a compound heterozygous variant c.[56C>A], p.(Ser19X) and c.[100G>A], p.(Ala34Thr) in the PNPLA1 gene [NM_001145717; exon 1]. The protein encoded by PNPLA1 acts as a unique transacylase that specifically transfers linoleic acid from triglyceride to ω-hydroxy fatty acid in ceramide, thus giving rise to ω-O-acylceramide, a particular class of sphingolipids that is essential for skin barrier function. The variant was located in the patatin core domain of PNPLA1 and resulted in a truncated protein which could disrupt the function of the protein. This case report highlights a novel compound heterozygous mutation in PNPLA1 identified in a Chinese child.

Harlequin Ichthyosis in a Filipino newborn: Management pearls in a resource-limited setting

Introduction@#Harlequin ichthyosis (HI) is a rare type of autosomal recessive congenital ichthyosis. There are approximately 200 documented cases worldwide, with less than five published reports in the Philippines. Despite its rarity, current literature suggests a better prognosis for these patients. @*Case description@#We describe a preterm male newborn who presented at birth enclosed in a thick hyperkeratotic armor-like scale plates with areas of fissures, with associated ectropion, conjunctiva dehiscence, and eclabium. The thickened encasement also covered the hands and feet, causing severe contractures. A diagnosis of harlequin ichthyosis was given based on the clinical features. The patient was managed through a multidisciplinary approach, including referral to the tele-ichthyosis platform of a US-based foundation for patients with ichthyosis. Thermoregulation, nutrition, and hydration were carefully managed. Bland emollients were applied generously following normal saline soaks to improve barrier protection. Acitretin was administered on day 2 of life to facilitate the desquamation of the thickened encasement. A marked decrease in erythema and the thickness of the hyperkeratotic skin, and reduced conjunctival dehiscence were noted after one week of therapy. However, the constrictions on the hands and feet showed bluish discoloration and signs of necrosis. Linear band excision was performed to release the constrictors. Despite aggressive management, the patient succumbed to sepsis on day 12 of life. @*Conclusion@#Improved prognosis amongst HI patients is correlated with optimal quality of care regardless of resource limitations. A multidisciplinary approach and early administration of retinoids cannot be overemphasized. Linear band excision within the first week of life is suggested for constrictions on the extremities that do not improve with retinoids to avoid necrosis and autoamputation.

Ictiosis arlequín: presentación de un caso / Harlequin ichthyosis: presentation of a case

RESUMEN Las genodermatosis ictiosiformes constituyen un grupo heterogéneo de trastornos de la cornificación caracterizados por hiperqueratosis y descamación de la piel. La ictiosis arlequín es la forma más grave y agresiva de las ictiosis congénitas, presenta una baja prevalencia (1/300 000 nacimientos) con expresividad clínica variable, una evolución desfavorable y pronóstico reservado. Se presenta con un patrón autosómico recesivo y su diagnóstico prenatal es aún difícil. Se presentó el caso de un recién nacido masculino pretérmino de 34 semanas gestacionales, sin historia familiar de trastornos de piel, con un cuadro característico de ictiosis arlequín, quien falleció a los 11 días de vida. Se realizó la caracterización clínica y anatomopatológica de la enfermedad y se ofrece una revisión sobre esta rara entidad (AU).

ABSTRACT Ichthyosiform genodermatoses are a heterogeneous group of cornification disorders characterized by hyperkeratosis and skin flaking. Harlequin ichthyosis is the most aggressive and serious form of congenital ichthyoses, presenting a low prevalence (1/300 000 births), with variable clinical expressivity, an unfavorable evolution and reserved prognosis. It appears with an autosomal recessive pattern and its prenatal diagnosis is still difficult. The authors present the case of a male preterm newborn, of 34 gestational weeks, without family history of skin disorders, and clinical characteristics of Harlequin ichthyosis, who died at the 11 day of birth. The disease clinical and anatomopathologic characterization was carried out and a review of this rare entity is made (AU).

Ictiose lamelar com apresentação na vida adulta: relato de caso / Ichthyosis lamellar with presentation in adult life: case report

Contexto: A ictiose lamelar é uma genodermatose rara, de herança autossômica recessiva. Pode ser causada por diferentes genes, principalmente mutação no gene TGM1 (transglutaminase 1) no cromossomo 14, e tem incidência de 1 caso em cada 200 mil nascidos vivos. A ictiose lamelar é causa de importante impacto na qualidade de vida. Relato da comunicação: Paciente do sexo feminino, 44 anos, procura atendimento médico para investigação de sintomas psiquiátricos, os quais foram avaliados. Foi afastado qualquer quadro psiquiátrico. Encaminhada à dermatologia, devido a evidente descamação lamelar disseminada, queratodermia palmoplantar, onicodistrofias e ectrópio bipalpebral. O exame clínico dermatológico e a avaliação histopatológica, evidenciaram características de ictiose lamelar, nunca tratada. Discussão: A ictiose lamelar é, na maioria das vezes, diagnosticada ao nascimento, com apresentação clínica muitas vezes sob a forma de bebê colódio. Este caso apresentou-se na vida adulta, com história desde o nascimento e, portanto, descartou-se a ictiose adquirida, relacionada a afecções nutricionais, metabólicas ou até paraneoplásicas. Conclusões: Este caso ilustra as manifestações da ictiose lamelar em paciente adulta em sua evolução natural, sem a interferência de tratamento.

Harlequin Ichthyosis in a 4-year-old male: Case report

@#Harlequin ichthyosis (HI) is a rare type of congenital keratinization disorder that, when left untreated, usually leads to early neonatal demise. A clinical diagnosis of HI is considered when a patient presents with thick plate-like scaling of the skin together with eclabium, ectropion, and nasal hypoplasia. The diagnosis can be confirmed by genetic testing to determine mutation in the adenosine triphosphate-binding cassette A12 (ABCA12) gene. Early administration of systemic retinoids to promote desquamation and emollients to control excessive scaling and dryness of the skin lead to better prognosis in most cases of HI. We present the case of a 4-year-old male with HI who has been successfully managed with bland emollients and systemic acitretin therapy, which we started when he was 1 year old.

Morfeia generalizada em uma criança com ictiose arlequim, uma associação rara / Generalized morphea in a child with harlequin ichthyosis: a rare association

Resumo Introdução Ictiose arlequim é uma doença cutânea congênita grave, autossômica e rara, caracterizada por ressecamento excessivo da pele e hiperqueratose. A associação de ictiose com esclerose sistêmica foi descrita em apenas três crianças. Ainda não foi descrito nenhum paciente com morfeia generalizada (MG) associada à ictiose arlequim. Relato de caso: Menina de quatro anos e seis meses de idade com diagnóstico de ictiose arlequim baseado em espessamento cutâneo difuso, com fissuras, descamação, eritema e sangramento da lesão desde as primeiras horas de vida. A paciente foi tratada com acitretina (1,0 mg/kg/dia) e creme emoliente. Aos três anos e nove meses, desenvolveu contraturas musculares com dor à movimentação e limitação nos cotovelos e joelhos e placas esclerodérmicas difusas no abdômen, nas costas, na região suprapúbica e nas extremidades inferiores. A biópsia de pele mostrou epiderme retificada e hiperqueratose leve, derme reticular com linfócitos, infiltrado mononuclear perivascular e perianexial e esclerose da derme reticular e glândula sudorípara rodeada por um tecido colágeno denso, compatível com esclerodermia. A paciente preencheu os critérios para o subtipo MG. Metotrexato e prednisona foram introduzidos. Aos quatro anos e três meses, apresentou novas lesões esclerodérmicas, associando-se azatioprina à terapêutica anterior, sem resposta após dois meses. Discussão: Um caso de ictiose arlequim associada à MG foi descrito. O tratamento dessas duas condições é um desafio e requer uma equipe multidisciplinar.

Abstract Introduction: Harlequin ichthyosis (HI) is a severe and rare hereditary congenital skin disorder characterized by excessive dryness, ectropion and eclabion. The association of ichthyosis with systemic sclerosis has been described in only three children. No patient with generalized morphea (GM) associated with harlequin ichthyosis was described. Case report: A 4-years and 6-months girl, diagnosed with harlequin ichthyosis based on diffuse cutaneous thickening, scaling, erythema, ectropion and eclabium since the first hours of birth was described. She was treated with acitretin (1.0 mg/kg/day) and emollient cream. At 3 years and 9 months, she developed muscle contractures with pain on motion and limitation in elbows and knees, and diffuse sclerodermic plaques on the abdomen, back, suprapubic area and lower limbs. Skin biopsy showed rectified epidermis and mild hyperorthokeratosis, reticular dermis with perivascular and periadnexal infiltrates of lymphocytes and mononuclear cells, and reticular dermis and sweat gland sclerosis surrounded by a dense collagen tissue, compatible with scleroderma. The patient fulfilled the GM subtype criteria. Methotrexate and prednisone were introduced. At 4 years and 3 months, new scleroderma lesions occurred and azathioprine was associated with previous therapy, with no apparent changes after two months. Discussion: A case of harlequin ichthyosis associated with a GM was reported. The treatment of these two conditions is a challenge and requires a multidisciplinary team.

Scanning electron microscopy of the collodion membrane from a self-healing collodion baby

AbstractSelf-healing collodion baby is a well-established subtype of this condition. We examined a male newborn, who was covered by a collodion membrane. The shed membrane was examined with scanning electron microscopy. The outer surface showed a very compact keratin without the normal elimination of corneocytes. The lateral view of the specimen revealed a very thick, horny layer. The inner surface showed the structure of lower corneocytes with polygonal contour. With higher magnifications villous projections were seen in the cell membrane.

Objetivos: Describir las manifestaciones oftalmológicas de la ictiosis congénita. Materiales y Métodos: Estudio retrospectivo de 8 pacientes con ictiosis lamelar congénita atendidos en el servicio de oftalmología del Hospital de Pediatría Prof. Dr. Juan P. Garrahan. Se analizaron: edad, sexo, posicionamiento de los párpados, la presencia de lagoftalmos, alteraciones de la superficie ocular y tratamientos tópicos y quirúrgicos instaurados para la patología ocular. Resultados: Se estudiaron 16 ojos de 8 pacientes, 7 de sexo masculino y 1 de sexo femenino. Cinco pacientes presentaron ictiosis lamelar clásica y 2 eritrodermia congénita ictiosiforme (EIC). La edad media de los pacientes fue de 30,6 meses (r= 15 días y 108 meses). Los hallazgos oftalmológicos observados fueron: queratitis y lagoftalmos en el 50% de los pacientes, ectropión en el 37,5% y absceso corneal en ambos ojos de 1 paciente. Todos los pacientes fueron tratados de primera instancia con lubricantes, 2 se trataron con eritromicina tópica ante la presencia de secreción y sólo 1 paciente requirió tratamiento con colirio fortificado y colocación de membrana amniótica. Conclusión: la ictiosis congénita produce alteraciones en los párpados y en la superficie corneal con alto riesgo de secuelas y pérdida visual. Los controles periódicos son indispensables para poder prevenir las lesiones y sus complicaciones (AU)

Aim: To describe the ophthalmological manifestations of congenital ichthyosis. Material and Methods: A retrospective study of eight patients with congenital lamellar ichthyosis was conducted at the Department of Ophthalmology of the Pediatric Hospital Prof. Dr. Juan P. Garrahan. Age, sex, eyelid position, presence of lagophthalmos, ocular surface alterations, as well as topical and surgical eye treatment were analyzed. Results: 16 eyes of 8 patients, 7 male and 1 female, were studied. Five patients had classical lamellar ichthyosis and two had congenital ichthyosiform erythroderma (CIE). Mean age of the patients was 30.6 months (r, 15 days to 108 months). Ophthalmological findings were: keratitis and lagophthalmos in 50% of patients, ectropion in 37.5%, and corneal abscess in both eyes in one patient. All patients were initialy treated with artificial tears, two were treated with topical erythromycin because of secretion, and only one patient needed treatment with fortified eye drops and placement of amniotic membrane. Conclusion: Congenital ichthyosis causes disorders of the eyelids and corneal damage with a high risk of sequelae and vision loss. Periodic controls are necessary to prevent the lesions and their complications (AU)
