Mini-implant assisted palate expansion and digital design in junctional epidermolysis bullosa and amelogenesis imperfecta: Case report.

BACKGROUND: Junctional epidermolysis bullosa (JEB) is one of the four major types of EB caused by genetic variants in the genes coding the proteins of the lamina lucida. All patients with this major type of EB present syndromic hypoplastic amelogenesis imperfecta (AI), with either a pits and fissures or generalized hypoplastic phenotype. Severe forms of AI are associated with compromised oral health-related quality of life (QoL) mostly due to poor dental aesthetics, dentofacial anomalies, and oral pain. AIM: To present the comprehensive dental treatment of a patient with JEB and AI from the age of 20 months until the age of 18 years, including complex orthodontics and digital oral rehabilitation. MATERIALS AND METHODS: A male patient with intermediate JEB (homozygous c.3228+1G>A LAMB3 variant) has been under the care of the special care dentistry clinic of the University of Chile since the age of 20 months. His complex dental needs include structural enamel abnormalities in primary and permanent dentition (hypoplastic generalized AI), severe dental crowding with maxillary compression, Class III skeletal pattern, agenesia (#45), and gingivitis. RESULTS: Pediatric dental care included oral hygiene education and preventive strategies (prophylaxis and fluoride applications), maintaining the dentition free of caries. Due to AI, severe tooth sensitivity hindered proper oral hygiene and required early rehabilitation with temporary polycarbonate and metallic crowns. At the age of 16, the patient began orthodontic treatment. A maxillary expansion was performed with two consecutive mini-implant assisted rapid palate expansion (MARPE) bonded to four mini-implants in the palate. After finishing orthodontic treatment metallic multibrackets (duration 19 months), a definitive oral rehabilitation based on digital smile design with feldspathic crowns of all anterior teeth and premolars was performed. CONCLUSION: Patients with severe generalized hypoplastic syndromic AI associated with JEB benefit from long-term preventive oral care. Complex orthodontic techniques, such as MARPE, and multibrackets can be successfully. Digital smile design provides a definitive oral rehabilitation technique improving oral function, aesthetics, and QoL.

Advantages of whole-exome sequencing over immunomapping in 67 Brazilian patients with epidermolysis bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is characterized by skin fragility and blistering. In Brazil, the diagnosis is usually obtained through immunomapping, which involves a skin biopsy. Most recently, whole exome sequencing (WES) has become an important tool for the diagnosis of the subtypes of EB, providing information on prognosis as well as allowing appropriate genetic counseling for the families. OBJECTIVE: To compare the results of immunomapping and molecular analysis and to describe the characteristics of a Brazilian cohort of patients with EB. METHODS: Patients were submitted to clinical evaluation and WES using peripheral blood samples. WES results were compared to those obtained from immunomapping testing from skin biopsies. RESULTS: 67 patients from 60 families were classified: 47 patients with recessive dystrophic EB (DEB), 4 with dominant DEB, 15 with EB simplex (EBS), and 1 with junctional EB (JEB). Novel causative variants were: 10/60 (16%) in COL7A1 associated with recessive DEB and 3 other variants in dominant DEB; one homozygous variant in KRT5 and another homozygous variant in PLEC, both associated with EBS. Immunomapping was available for 59 of the 67 patients and the results were concordant with exome results in 37 (62%), discordant in 13 (22%), and inconclusive in 9 patients (15%). STUDY LIMITATIONS: Even though EB is a rare disease, for statistical purposes, the number of patients evaluated by this cohort can still be considered limited; other than that, there was a significant difference between the proportion of types of EB (only one case with JEB, against more than 50 with DEB), which unfortunately represents a selection bias. Also, for a small subset of families, segregation (usually through Sanger sequencing) was not an option, usually due to deceased or unknown parent status (mostly the father). CONCLUSION: Although immunomapping has been useful in services where molecular studies are not available, this invasive method may provide a misdiagnosis or an inconclusive result in about 1/3 of the patients. This study shows that WES is an effective method for the diagnosis and genetic counseling of EB patients.

Hereditary epidermolysis bullosa: clinical-epidemiological profile of 278 patients at a tertiary hospital in São Paulo, Brazil.

BACKGROUND: Epidermolysis bullosa (EB) is a group of rare hereditary diseases, characterized by fragility of the skin and mucous membranes. Epidemiological data on EB in Brazil are scarce. OBJECTIVES: To describe epidemiological aspects of patients with EB diagnosed in the Dermatology Department of a tertiary hospital, from 2000 to 2022. METHODS: An observational and retrospective study was conducted through the analysis of medical records. The evaluated data included clinical form, sex, family history, consanguinity, age at diagnosis, current age, time of follow-up, comorbidities, histopathology and immunomapping, presence of EB nevi and squamous cell carcinomas (SCC), cause of and age at death. RESULTS: Of 309 patients with hereditary EB, 278 were included. The most common type was dystrophic EB (DEB), with 73% (28.4% dominant DEB, 31.7% recessive DEB and 12.9% pruriginous DEB). Other types were junctional EB with 9.4%, EB simplex with 16.5% and Kindler EB with 1.1%. Women accounted for 53% and men for 47% of cases. Family history was found in 35% and consanguinity in 11%. The mean age at diagnosis was 10.8 years and the current age was 26 years. The mean time of follow-up was nine years. Esophageal stenosis affected 14%, dental alterations affected 36%, malnutrition 13% and anemia 29%. During diagnostic investigation, 72.6% underwent histopathological examination and 92% underwent immunomapping. EB nevi were identified in 17%. Nine patients had SCC. Eleven patients died. STUDY LIMITATIONS: Insufficient data included to medical records, loss to follow-up, and unavailability of genetic testing. CONCLUSIONS: In this study, dystrophic EB predominated and the need for multidisciplinary care for comorbidities and complications was highlighted.

Oleogel-S10 in Dystrophic Epidermolysis Bullosa: A Case Series Evaluating the Impact on Wound Burden Over Two Years.

Epidermolysis bullosa (EB) is a group of rare, difficult-to-treat, inherited multisystem diseases affecting epithelial integrity. Impaired wound healing is central and can lead to serious clinical complications, deformities, and symptoms with a devastating impact on quality of life (QoL). Dressing changes and wound care are central to the management of EB. Recently Oleogel-S10 (also known as birch bark extract or birch triterpenes) was approved in Europe and the UK for treating EB wounds. This approval was based on data from the EASE phase 3 study, which demonstrated Oleogel-S10 accelerated wound healing, reduced total wound burden, and decreased the frequency of dressing changes in patients with EB. A retrospective analysis of medical records was conducted for up to 24 months in 13 patients with EB treated with Oleogel-S10 through an early access programme in Colombia. Effectiveness was assessed by measuring body surface area percentage (BSAP) and total body wound burden (EBDASI). Tolerability and safety were monitored throughout. This is the first report to evaluate the effectiveness of Oleogel-S10 in clinical practice. The results showed a reduction in percentage of BSA affected, from a mean of 27.3% at baseline to 10.4% at 24-month follow-up, despite treatment interruptions. A reduction in EBDASI skin activity score of - 16.2 (24 months) together with a reduced skin damage index score of - 15.4 (18 months) was also observed. Physicians, patients, and caregivers perceived faster wound closure. Adherence with therapy by patients was good, and patients expressed satisfaction with treatment and reported improvements in self-esteem, productivity, and social interaction. Oleogel-S10 was well tolerated; however, two patients reported worsening wounds related to gauze adherence. Two deaths during treatment interruption were reported and was not considered related to Oleogel-S10. This study supports the effectiveness of Oleogel-S10 in a real-world scenario in a country with scarce resources for the treatment of EB.

Comprehensive orthodontic treatment using miniscrews and digital rehabilitation in a patient with severe recessive dystrophic epidermolysis bullosa.

INTRODUCTION: Epidermolysis bullosa (EB) is a rare genetic disorder characterized by skin fragility and blister formation. The phenotypic presentation is broad with four major types, being Recessive Dystrophic EB (RDEB) the most severe, including oral anomalies such as severe microstomia, ankyloglossia, vestibule obliteration and occlusal anomalies, turning orthodontic treatment into a challenge. AIM: This case report aims to present the comprehensive treatment of a patient with severe RDEB, including periodontal surgery, orthodontic fixed braces with mini-screws and oral rehabilitation with anterior veneers. CASE REPORT: A 27-year-old female patient with severe RDEB received orthodontic treatment in the upper jaw to improve malalignment and anterior crossbite. After 13 months of treatment with fixed appliances, miniscrews were placed in the anterior segment to intrude and procline the upper incisors. Oral surgery was performed to increase the vestibule depth of the upper lip. Once edge-to-edge occlusion was obtained, anterior veneers were placed to improve aesthetic and stabilize occlusion, especially with the lack of posterior support. DISCUSSION: The multidisciplinary treatment approach, involving orthodontic treatment, periodontal surgery and oral rehabilitation, played a crucial role in achieving favorable results. This case highlights the successful use of miniscrews as a viable orthodontic approach for patients with severe RDEB.

Acquired epidermolysis bullosa in a pediatric patient.

BACKGROUND: Acquired epidermolysis bullosa is a rare and chronic autoimmune subepidermal bullous disease characterized by the formation of autoantibodies against type VII collagen. Presentation in childhood is rare and with several manifestations. CASE REPORT: We report the case of a 12-year-old female patient who presented bullous and polymorphic lesions on the chest and extremities of several months of evolution. Due to the characteristics of the skin lesions, a histopathological and direct immunofluorescence study was conducted, confirming the diagnosis of acquired epidermolysis bullosa. Subsequently, corticosteroid and dapsone treatment was administered, with favorable clinical response during follow-up. CONCLUSIONS: Acquired epidermolysis bullosa is unusual in pediatric age, so it should be considered in the differential diagnosis of other congenital and acquired bullous diseases of childhood. The definitive diagnosis is performed through an immunofluorescence, study, which allows for rapid and effective treatment to control the disease and avoid permanent sequelae.

INTRODUCCIÓN: La epidermólisis bullosa adquirida es una enfermedad ampollar subepidérmica autoinmune, rara y crónica caracterizada por la formación de autoanticuerpos contra colágeno tipo VII. La presentación en la infancia es poco frecuente y con manifestaciones variables. CASO CLÍNICO: Se describe el caso de una paciente de sexo femenino de 12 años de edad que presentó lesiones ampollares y polimórficas en tórax y extremidades de varios meses de evolución. Por las características de las lesiones cutáneas, se realizó un estudio histopatológico y de inmunofluorescencia directa que confirmó el diagnóstico de epidermólisis bullosa adquirida, por lo que se administró tratamiento con corticoide y dapsona, con una respuesta clínica favorable durante el seguimiento. CONCLUSIONES: La epidermólisis bullosa adquirida es inusual en la edad pediátrica. Por tanto, debe considerarse en el diagnóstico diferencial de otras enfermedades ampollares congénitas y adquiridas de la infancia. El diagnóstico definitivo se realiza a través del estudio de inmunofluorescencia, lo que permite instaurar rápidamente un tratamiento rápido y eficaz para controlar la enfermedad y evitar secuelas permanentes.

Maintenance of chronicity signatures in fibroblasts isolated from recessive dystrophic epidermolysis bullosa chronic wound dressings under culture conditions.

BACKGROUND: Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a rare inherited skin disease caused by variants in the COL7A1 gene, coding for type VII collagen (C7), an important component of anchoring fibrils in the basement membrane of the epidermis. RDEB patients suffer from skin fragility starting with blister formation and evolving into chronic wounds, inflammation and skin fibrosis, with a high risk of developing aggressive skin carcinomas. Restricted therapeutic options are limited by the lack of in vitro models of defective wound healing in RDEB patients. RESULTS: In order to explore a more efficient, non-invasive in vitro model for RDEB studies, we obtained patient fibroblasts derived from discarded dressings) and examined their phenotypic features compared with fibroblasts derived from non-injured skin of RDEB and healthy-donor skin biopsies. Our results demonstrate that fibroblasts derived from RDEB chronic wounds (RDEB-CW) displayed characteristics of senescent cells, increased myofibroblast differentiation, and augmented levels of TGF-ß1 signaling components compared to fibroblasts derived from RDEB acute wounds and unaffected RDEB skin as well as skin from healthy-donors. Furthermore, RDEB-CW fibroblasts exhibited an increased pattern of inflammatory cytokine secretion (IL-1ß and IL-6) when compared with RDEB and control fibroblasts. Interestingly, these aberrant patterns were found specifically in RDEB-CW fibroblasts independent of the culturing method, since fibroblasts obtained from dressing of acute wounds displayed a phenotype more similar to fibroblasts obtained from RDEB normal skin biopsies. CONCLUSIONS: Our results show that in vitro cultured RDEB-CW fibroblasts maintain distinctive cellular and molecular characteristics resembling the inflammatory and fibrotic microenvironment observed in RDEB patients' chronic wounds. This work describes a novel, non-invasive and painless strategy to obtain human fibroblasts chronically subjected to an inflammatory and fibrotic environment, supporting their use as an accessible model for in vitro studies of RDEB wound healing pathogenesis. As such, this approach is well suited to testing new therapeutic strategies under controlled laboratory conditions.

Fibrosis as a Risk Factor for Cutaneous Squamous Cell Carcinoma in Recessive Dystrophic Epidermolysis Bullosa: A Systematic Review.

Recessive dystrophic epidermolysis bullosa (RDEB) is a severe subtype of epidermolysis bullosa caused by changes in collagen VII with a high risk of early development of cutaneous squamous cell carcinoma (cSCC). This review aimed to discuss the relationship between the recurrent healing process, the appearance of fibrosis, and malignant epithelial transformation in RDEB. We searched PubMed, the Regional Portal of the Virtual Health Library, and Embase for articles on the relationship between blistering, recurrent scarring, and fibrosis in the context of cSCC and RDEB. That alterations of collagen VII result in blister formation, scar deficiency associated with inflammation, and increased expression of transforming growth factor ß. These events promote the differentiation of myofibroblasts and the expression of profibrotic proteins, leading to structural changes and the establishment of a microenvironment favorable to carcinogenesis. Patients with RDEB and areas of recurrent scarring and fibrosis may be more prone to the development of cSCC.

Síndrome de Bart: aplasia cutis congénita y epidermólisis bullosa / Bart's syndrome: aplasia cutis congenita and epidermolysis bullosa

La aplasia cutis congénita, también conocida como síndrome de Bart, ha sido asociada con todos los subtipos principales de epidermólisis bullosa. Esta enfermedad afecta a 1 por cada 10 000 recién nacidos vivos; solo se han descrito 500 casos en la literatura médica. Se caracteriza por afectar un miembro inferior con patrón en forma de S y presentar lesiones de epidermólisis bullosa en cualquier otra parte del cuerpo. Se presenta el caso de una neonata con las características clínicas mencionadas, hospitalizada en el Servicio de Neonatología del Hospital Pediátrico Universitario «José Luis Miranda». Este diagnóstico es principalmente clínico y se basa en la evidencia de áreas de pérdida cutánea con predominio en miembros inferiores, lesiones ampollares en piel y mucosas, y deformidades ungueales. Su pronóstico puede ser fatal. Este caso reviste gran interés por su baja incidencia; su diagnóstico precoz contribuyó a evitar complicaciones.

Aplasia cutis congenita, also known as Bart's syndrome, has been associated with all the major epidermolysis bullosa subtypes. This disease affects 1 in 10, 000 live births; only 500 cases have been described in medical literature. It is characterized by affecting a lower limb with an S-shaped pattern and presenting epidermolysis bullosa lesions in any other part of the body. We present a female neonate with the aforementioned clinical features, who was hospitalized in the Neonatology service at "José Luis Miranda" Pediatric University Hospital. This diagnosis is mainly clinical and is based on evidence of areas of skin loss predominantly on the lower limbs, bullous lesions on the skin and mucous membranes and nail deformities. Its prognosis can be fatal. This case is of great interest due to its low incidence; its early diagnosis helped to avoid complications.

Epidermolysis bullosa in oral health: clinical manifestations and salivary alterations.

Epidermolysis bullosa (EB) is an inherited disease characterized by the fragility of the skin and mucous membranes. All types/subtypes of EB can lead to alterations in the mouth and glands. OBJECTIVE: To evaluate clinical manifestations of EB on the oral mucosa and alterations in salivary flow. MATERIALS AND METHODS: Sociodemographic and clinical data were obtained from EB individuals. The salivary flow analysis was performed in EB and in non-EB patients. Fischer's exact test was applied to the qualitative variables, and the Mann-Whitney test was applied to the quantitative data. RESULTS: A total of 11 cases of EB were evaluated, and 3 types of EB were diagnosed (recessive dystrophic-RDEB; junctional-JEB; and simplex-EBS). Only individuals with RDEB or JEB showed the oral manifestation of the disease. The most affected sites were the lips (54%), hard palate (36%), and oral mucosa (27%). Ulcer and ankyloglossia were diagnosed in all RDEB cases. Regarding salivary flow, an intragroup comparison revealed an increase in stimulated versus unstimulated collection in the control sample (p = 0.0064). The EB group showed no difference (p = 0.6086). We also observed no differences in salivary volume between the control and EB groups (p = 0.7117 and p = 0.5557, unstimulated and stimulated flows, respectively). CONCLUSIONS: No oral manifestations were observed in EBS subjects. It is unclear whether individuals with EB are predisposed to manifest hyposalivation. CLINICAL RELEVANCE: Severe cases of EB show broad alterations in the oral mucosa, whereas the saliva needs to be better evaluated.

Longitudinal study of wound healing status and bacterial colonisation of Staphylococcus aureus and Corynebacterium diphtheriae in epidermolysis bullosa patients.

Epidermolysis bullosa (EB) is an inherited disorder characterised by skin fragility and the appearance of blisters and wounds. Patient wounds are often colonised or infected with bacteria, leading to impaired healing, pain and high risk of death by sepsis. Little is known about the impact of bacterial composition and susceptibility in wound resolution, and there is a need for longitudinal studies to understand healing outcomes with different types of bacterial colonisation. A prospective longitudinal study of 70 wounds from 15 severe EB patients (Junctional and Recessive Dystrophic EB) from Chile. Wounds were selected independently of their infected status. Wound cultures, including bacterial species identification, composition and Staphylococcus aureus (SA) antibiotic susceptibility were registered. Wounds were separated into categories according to their healing capacity, recognising chronic, and healing wounds. Hundred-one of the 102 wound cultures were positive for bacterial growth. From these, 100 were SA-positive; 31 were resistant to Ciprofloxacin (31%) and only seven were methicillin-resistant SA (7%). Ciprofloxacin-resistant SA was found significantly predominant in chronic wounds (**P < .01). Interestingly, atoxigenic Corynebacterium diphtheriae (CD) was identified and found to be the second most abundant recovered bacteria (31/101), present almost always in combination with SA (30/31). CD was only found in Recessive Dystrophic EB patients and not related to wound chronicity. Other less frequent bacterial species found included Pseudomonas aeruginosa, Streptococus spp. and Proteus spp. Infection was negatively associated with the healing status of wounds.

Impression technique modification and oral contracture release surgery for orthodontic treatment in a patient with severe microstomia due to recessive dystrophic epidermolysis bullosa.

INTRODUCTION: Epidermolysis bullosa (EB) is a group of genetic disorders characterized by fragility of the skin and mucosal membranes. Dystrophic EB (DEB) is caused by mutations in the gene coding for type VII collagen. Among the most frequent oral manifestations in Recessive DEB (RDEB) are oral ulcers and blisters, absence of tongue papillae and palatal rugae, ankyloglossia, oral vestibule obliteration, and microstomia. The following report describes a modified impression technique used in a patient with severe RDEB and severe microstomia to obtain models for orthodontic treatment with aligners. CASE REPORT: A 25-year-old female patient with severe RDEB was referred for orthodontic treatment. Severe microstomia (8 mm), hindered the use of conventional trays or intraoral scanners to design the aligners. Therefore, a contracture release surgery in combination with a modified impression technique was performed to obtain an optimal impression and subsequent aligners for orthodontic treatment. DISCUSSION: This case presents an alternative strategy to provide orthodontic treatment with aligners in patients with severe microstomia due to severe RDEB. Reports of orthodontic treatment in people living with EB, especially in RDEB, are still rare, with few publications about fixed braces, early teeth extraction and removable devices, and none using aligners. Most of the impression techniques reported are aimed at oral rehabilitation. The multidisciplinary approach and impression technique reported should broaden the alternatives of orthodontic techniques provided to patients with EB and severe microstomia. CONCLUSIONS: This article describes an oral contracture release surgery and modified impression technique for obtaining good quality impression for the design of orthodontic aligners in patients with severe microstomia due to severe RDEB.

Método estudio descriptivo de abordaje cualitativo desarrollado junto a diez madres de niños y adolescentes con Epidermólisis Bullosa de diferentes regiones de Brasil, a partir de entrevistas semiestructuradas con grabación de audio y video, por vía remota, utilizando la plataforma Google Meet®, entre septiembre y noviembre de 2021. La técnica de análisis temático dirigió la apreciación del material empírico. Resultados participaron en el estudio mujeres de entre 23 y 53 años. Dos categorías traducen la experiencia materna: i) El "shock" del diagnóstico y los retos iniciales; y ii) "Dejar de vivir para vivir por él": los cambios en la vida cotidiana de las familias. Consideraciones finales e implicaciones para la práctica las madres experimentaron sentimientos de miedo e inseguridad ante el diagnóstico de su hijo y la rutina de cuidados, especialmente los cambios de apósito diarios provocaron una sobrecarga física y emocional. Estos resultados pueden servir de apoyo para el seguimiento de estas familias, con el fin de poder cuidarlas y apoyarlas emocionalmente.

Abstract Objective to know and analyze mothers' experiences in caring for children and adolescents with Epidermolysis Bullosa. Method a descriptive qualitative study was developed with ten mothers of children and adolescents with epidermolysis bullosa from different regions of Brazil using semi-structured interviews recorded remotely using Google Meet® between September and November 2021. The thematic analysis technique guided the appreciation of the empirical material. Results mothers aged between 23 and 53 years participated in the study. Two categories translate the maternal experience: i) the "shock" of the diagnosis and the initial challenges and ii) "Stop living to live for them": the changes in the families' daily life. Final considerations and implications for practice mothers experienced fear and insecurity when their child was diagnosed, and the care routine, especially the daily dressing changes, caused a physical and emotional burden. These results can support the follow-up of these families to provide them with care tools and emotional support.

Abstract Objective To analyze the scientific production regarding actions/Nursing Interventions in hospital environments related to the care of children and adolescents with epidermolysis bullosa. Methods This is a systematic review, which was searched in the CINAHL, MEDLINE®/PubMed®, Scopus, LILACS and SciELO databases, carried out from September 2020 to January 2021. For the search, the descriptors "epidermólise bolhosa" AND "criança" AND "adolescente" AND "enfermagem" were used, in Portuguese, in the LILACS and SciELO databases, and "epidermolysis bullosa" AND "children" AND "adolescent" AND "nursing" in the other databases. Results There was a greater number of articles published based on the guiding question having the United States as the country of origin (22%). Most of the classification was at level VI (44%) of scientific evidence. Still, 86% of studies involved research for the care plan. The evidence found resulted from expert opinions, case studies and consensus. The most cited care factors were skin care plans, diaper changing, clothing care and non-stick coating use. Conclusion The surveys reported difficulties regarding the availability of materials, treatment and specialized professionals, in addition to limitations of knowledge in clinical practice focused on the characteristics of epidermolysis bullosa. Among the care, there was emphasis on information about the wound complexity and characteristics as a way of anticipating care strategies.

Epidermólisis bulosa distrófica recesiva en mujer embarazada. Reporte de caso / Recessive dystrophic epidermolysis bullosa in pregnant women. Case report

Resumen INTRODUCCIÓN: La epidermólisis bulosa engloba a un grupo de enfermedades caracterizadas por una fragilidad extrema de la piel y membranas mucosas, consecuencia de la formación de ampollas posterior a un traumatismo mínimo. Hay tres tipos principales de epidermólisis. Se comunica el caso para hacer notar las implicaciones del cuidado al momento del nacimiento, y las consideraciones anestésicas. CASO CLÍNICO: Paciente de 25 años en su segundo embarazo con epidermólisis bulosa distrófica recesiva. El nacimiento fue electivo mediante cesárea, con anestesia regional. CONCLUSIONES: Debe tenerse especial cuidado durante las intervenciones terapéuticas a fin de evitar la formación de bulas o exacerbar las existentes. Las fuerzas de fricción son más dañinas que las de compresión. La planeación multidisciplinaria es necesaria para un desenlace sin complicaciones.

Abstract BACKGROUND: Epidermolysis bullosa encompasses a group of diseases characterized by extreme fragility of the skin and mucous membranes, resulting in the formation of blisters after minimal trauma; There are three main types of epidermolysis. The case is presented to highlight the implications of care both at the time of birth, as well as anesthetic considerations. CLINICAL CASE: A 25-year-old patient in her second pregnancy with recessive dystrophic epidermolysis bullosa. The birth was elective by caesarean section under regional anesthesia. CONCLUSIONS: Special care must be taken during therapeutic interventions to avoid the formation of bullae or exacerbate those already present. Friction forces are more damaging than compression forces. Multidisciplinary planning is necessary for a smooth outcome.

Atresia pilórica / Pyloric Atresia

Introducción: La atresia pilórica es una afección rara, que en el 40-50 por ciento de los casos se asocia a otras anomalías, frecuentemente con la epidermolisis bullosa, asociación conocida como síndrome de Carmi. Objetivo: Informar sobre la evolución de una paciente tratada por atresia pilórica que tenía además una epidermolisis bullosa. Presentación del caso: Recién nacida con antecedentes prenatales de polihidramnios, parto eutócico a las 30,4 semanas, sepsis ovular materna, peso al nacer 1430 gramos; múltiples lesiones en piel, ampollosas y aplasia cutis en pierna izquierda. Se ventiló desde sala de partos, La paciente no toleró la alimentación enteral mínima. Se realizó estudio radiográfico y no se visualizó paso de contraste al píloro. Se diagnosticó una atresia pilórica y se operó al cuarto día de nacida. La paciente tenía una atresia pilórica tipo 2: sustitución del tejido pilórico por tejido fibroso. Se hizo una gastroduodenostomía. En su evolución se incrementaron por día las lesiones en piel, y tuvo reapertura del ductus arterioso, trastornos hidroelectrolíticos, y hemidinámicos que provocaron el fallecimiento a los 14 días de nacida. Conclusiones: La atresia pilórica es una afección muy rara, que debe tenerse en cuenta en recién nacidos con epidermolisis bullosa por la frecuente asociación entre estas dos afecciones; además, cuando existen antecedentes de polihidramnios y no tolerancia a la alimentación enteral. Los pacientes con la asociación atresia pilórica y epidermolisis bullosa generalmente presentan una evolución desfavorable (AU)

Introduction: Pyloric atresia is a rare condition, which in 40-50 percent of cases is associated with other anomalies, often with epidermolysis bullosa, an association known as Carmi syndrome. Objective: To report on the evolution of a patient treated due to pyloric atresia who also had epidermolysis bullosa. Case presentation: Female newborn with prenatal history of polyhydramnios, eutocic delivery at 30.4 weeks, maternal ovular sepsis, birth weight 1430 grams, with multiple skin lesions, blisters and aplasia cutis in the left leg. She was ventilated from the delivery room. The patient did not tolerate minimal enteral feeding. A radiographic study was performed and no contrast passage to the pylorus was visualized. Pyloric atresia was diagnosed and operated on the fourth day of birth. The patient had pyloric atresia type 2: replacement of pyloric tissue by fibrous tissue. A gastroduodenostomy was done. In its evolution, skin lesions increased per day and reopening of the ductus arteriosus was performed, she had hydroelectrolyte disorders, and hemidynamic disorders that caused death at 14 days of birth. Conclusions: Pyloric atresia is a very rare condition, which should be taken into account in newborns with epidermolysis bullosa due to the frequent association between these two conditions, also when there is a history of polyhydramnios and no tolerance to enteral feeding. Patients with pyloric atresia and epidermolysis bullosa usually have an unfavorable outcome(AU)
