Manejo odontológico de pacientes con el síndrome de Ehlers-Danlos. Revisión narrativa / Dental management in patients with Ehlers-Danlos syndrome. Narrative review

Resumen El síndrome de Ehlers-Danlos es una enfermedad hereditaria, producida por mutaciones cromosómicas que pueden llegar a tener un comportamiento autosómico dominante, recesivo o ligado al cromosoma X. Se caracteriza por defectos en las enzimas encargadas de la estructura y síntesis de colágeno. En vista de los 20 tipos de colágeno que existen, este síndrome es extremadamente heterogéneo tanto en su presentación clínica como en su progresión y evolución. Dentro de los signos y síntomas habituales encontramos la hiperlaxitud articular, hiperelasticidad de la piel e hiperequimosis de los vasos sanguíneos. Con relación a las complicaciones que pueden presentar estos pacientes, encontramos dislocaciones articulares, fragilidad en la piel, dolor articular, ruptura de grandes vasos sanguíneos, dificultad en la cicatrización y, en consecuencia, mayor incidencia de procesos infecciosos y de cicatrices poco estéticas. Presenta una incidencia de 1 caso cada 2.500-5.000 nacidos vivos. Por ello, es fundamental que el odontólogo se encuentre familiarizado con el manejo médico-dental de estos pacientes, a fin de estar preparado para brindarles un tratamiento adecuado y responder ante las posibles complicaciones que se pueden presentar. En esta revisión se emplearon resultados extraídos manualmente de artículos, indexados en las bases de datos PUBMED y EBSCO, que respondían a la búsqueda de los términos Ehlers-Danlos syndrome, dental management y oral surgery. El objetivo fue describir el manejo médico-odontológico del paciente con síndrome de Ehlers-Danlos hasta la fecha.

Abstract Ehlers-Danlos syndrome is a hereditary disease, produced by chromosomal mutations that can have an autosomal behavior, which can be dominant, recessive or X-linked. It is characterized by defects in the enzymes responsible for the structure and synthesis of collagen. In view of the 20 existent types of collagen, this syndrome is extremely heterogeneous in its clinical presentation, as well as in its progression and evolution. Within the usual signs and symptoms, we find joint hyperlaxity, skin hyperelasticity and hyper-ecchymosis of the blood vessels. Regarding the complications that these patients can present, we find joint dislocations, skin fragility, joint pain, rupture of large blood vessels, difficulty in healing and, consequently, a higher incidence of infectious processes and unsightly scars. It presents an incidence of 1 case every 2.500-5.000 live births. Therefore, it is essential that the dentist is familiar with the medical-dental management of these patients, in order to be prepared to provide them with adequate treatment and respond to possible complications that may arise. In this review, results were manually extracted from articles, indexed in the PUBMED and EBSCO databases, that respond to the search for the terms Ehlers-Danlos syndrome, dental management and oral surgery. The aim was describing the medical-dental management of patients with Ehlers-Danlos syndrome to date.

Ictiosis vulgar asociada a síndrome de Ehlers Danlos tipo clásico en una niña / Ichthyosis Vulgaris Associated with Ehlers Danlos Syndrome Classic Type in a Girl

Introducción: La ictiosis vulgar y el síndrome de Ehlers Danlos tipo clásico integran dos genodermatosis que presentan en común un patrón de herencia autosómico dominante, pero muestran manifestaciones clínicas variadas. Es infrecuente encontrar concomitancia de ambas dermatosis en un mismo paciente, y cuando ocurre la heterogeneidad clínica hace complejo el diagnóstico. Objetivo: Exponer un caso que presentó ictiosis vulgar asociada con el síndrome de Ehlers Danlos tipo clásico, en el que el análisis del árbol genealógico contribuyó a orientar el diagnóstico. Presentación del caso: Paciente femenina de 10 años de edad, atendida en la consulta especializada de genodermatosis en Las Tunas. Presentaba, desde edades tempranas, lesiones escamosas localizadas en las piernas y brazos, y que empeoraban durante el invierno. Desde los nueve años comenzó a mostrar luxaciones frecuentes de hombro derecho e hiperextensibilidad de la piel. Constaban antecedentes familiares de piel escamosa en miembros de la familia materna e hipermovilidad articular en varios miembros de la familia paterna: El árbol genealógico contribuyó a orientar el diagnóstico y a realizar la atención médica adecuada. Conclusiones: Se trató un caso interesante porque resulta infrecuente encontrar en un mismo paciente dos enfermedades genéticas, lo cual implicó dificultades en el momento de confirmar el diagnóstico, así como su atención. A este diagnóstico, en el caso de ambas genodermatosis, contribuyó el análisis del árbol genealógico familiar, herramienta fundamental en la determinación de enfermedades genéticas(AU)

Introduction: Ichthyosis vulgaris and Ehlers Danlos syndrome classic type comprise two genodermatoses that share an autosomal dominant pattern of inheritance, but show varied clinical manifestations. It is rare to find concomitance of both dermatoses in the same patient, and when this occurs the clinical heterogeneity makes the diagnosis complex. Objective: To present a case of ichthyosis vulgaris associated with classic Ehlers Danlos syndrome, in which analysis of the family tree helped to guide the diagnosis. Case presentation: 10-year-old female patient seen at the specialised genodermatosis clinic in Las Tunas. She presented, from an early age, with scaly lesions located on the legs and arms, which worsened during the winter. From the age of nine he began to show frequent dislocations of the right shoulder and hyperextensibility of the skin. There was a family history of scaly skin in members of the maternal family and joint hypermobility in several members of the paternal family: the family tree helped to guide the diagnosis and appropriate medical care. Conclusions: This was an interesting case because it is rare to find two genetic diseases in the same patient, which implied difficulties at the time of confirming the diagnosis, as well as its care. The analysis of the family tree, a fundamental tool in the determination of genetic diseases, contributed to this diagnosis in the case of both genodermatoses(AU)

Metodología para la atención integral a pacientes con genodermatosis

Las genodermatosis constituyen un grupo de enfermedades genéticas con afectación de la piel y sus anexos. En Cuba, el Programa Nacional de Diagnóstico, Atención y Prevención de Enfermedades Genéticas, en relación a las genodermatosis, no cuenta con protocolos para su diagnóstico, tratamiento y seguimiento. El objetivo del estudio es evaluar una metodología para la atención a los pacientes con genodermatosis. Se realizó en Las Tunas, provincia oriental de Cuba, un estudio cuasi-experimental, aplicándose la variante Delphy del método de expertos, siendo consultados un grupo de especialistas cubanos de dermatología, genética médica clínica y pediatría, con alto nivel científico y experiencia en el trabajo con pacientes con genodermatosis. Diseñándose la metodología que propone el protocolo del diagnóstico, tratamiento y algoritmo de seguimiento para estos pacientes. Se estudiaron 395 pacientes atendidos en el Departamento provincial de Genética Médica. Se estudiaron la tasa de prevalencia, la media de casos diagnosticados por año, la proporción de complicaciones presentadas, el índice de supervivencia e índice de letalidad y para relacionar las variables referentes a la mejoría del estado dermatológico y manifestaciones extracutáneas se utilizó la prueba estadística de Chi cuadrado de Mc-Nemar, con una significación estadística p≤0,05. Después de implementada la metodología, predominó la neurofibromatosis 1, síndrome de Ehlers Danlos clásico e ictiosis vulgar, la media de casos diagnosticados por año aumentó; disminuyeron las complicaciones, predominando las piodermitis (6.13 %); el índice de mortalidad fue bajo (1.27%) con alto índice de supervivencia (98.73%) y mejoría de las manifestaciones dermatológicas (MCNemar X2=90.41558, P=0.000000) y extracutáneas (McNemar X2=24.083334, P=0.000001). La metodología diseñada para la atención a pacientes con genodermatosis fortalece el Programa Nacional de Diagnóstico, Atención y Prevención de Enfermedades Genéticas, demostrando ser efectiva, con mayor número de casos diagnosticados, menor proporción de complicaciones, alta supervivencia, baja letalidad y mejoría clínica de las manifestaciones dermatológicas y extracutáneas.

The genodermatoses constitutes a group of genetic diseases with affectation of the skin and their annexes. In Cuba, the National Program of Diagnostic, Attention and Prevention of Genetic diseases, in relation to the genodermatoses, don't have protocols for their diagnosis, treatment and pursuit. The objective of this study is to evaluate a methodology for the attention to the patients with genodermatosis. Was carried out in The Tunas, oriental county of Cuba, a quasi-experimental study, being applied the varying Delphy of the method of experts, being consulted a group of Cuban specialists of dermatology, genetics clinical doctor and pediatrics, with high scientific level and experience in the work with patient with genodermatoses.

The 496th case:recurrent syncope for 8 years / 中华内科杂志

A 25-year-old women was admitted to the department of Neurology in Affiliated 2nd Hospital of Hainan Medical University due to recurrent syncope for 8 years and return for 2 months. She had multiple episodes of syncope at onset. She presented with the feeling of weakness in both lower limbs, and fatigue in the past year. She experienced pain in the waist and limbs joint in recent three months. Physical examination showed joint hyperactivity in metacarpophalangeal joints of both upper limbs, increased skin elasticity. Active-standing transcranial Doppler (TCD) test showed that the average heart rate (HR) and the average middle cerebral artery (MCA) blood flow velocity in the supine position were 79 beats/min and 62 cm/s, respectively; while the average HR and the average MCA blood flow velocity in the standing position were 126 beats/min, 47 cm/s. Meanwhile,the blood pressure was normal during the test of supine-to-standing TCD. Genetic testing indicated LDB3 transgenation. The patient was diagnosed as postural tachycardia syndrome (joint-hypermobility-related), Ehlers-Danlos syndrome, and relieved by fluid infusion and rehabilitation therapy.

Estudios de agregación plaquetaria como endofenotipo de las alteraciones hereditarias de la fibra colágena / Platelet aggregation studies as an endophenotype of hereditary disorders of collagen fiber

Introducción: Las plaquetas contribuyen a la hemostasia y la interrupción heredada o adquirida; en sus procesos bioquímicos pueden alterar la función plaquetaria. Estos trastornos de agregación se han asociado a enfermedades genéticas con afectación del tejido conectivo como el síndrome Ehlers-Danlos, cuyo diagnóstico diferencial con el espectro de hipermovilidad articular resulta difícil clínica y molecularmente. Estas entidades con afectación en las fibras colágenas y diferente repercusión clínica precisan diferenciales en su diagnóstico clínico. Métodos: Se revisaron 353 historias clínicas de pacientes atendidos en el Servicio de Genética del Hospital Pediátrico William Soler desde septiembre del 2009 al 2012, con diagnóstico de hipermovilidad articular por criterios de Beighton y de Ehlers-Danlos según Villefranche (1997). Se incluyó a los pacientes de 5-18 años con resultados documentados del estudio de agregación plaquetaria, valorados por especialistas en hematología. Resultados: Se encontraron trastornos de agregación plaquetaria en 79 de 86 pacientes (92 por ciento). En 7 casos con hipermovilidad de 65 con este diagnóstico (10 por ciento), los resultados fueron negativos. Los 21 con síndrome Ehlers-Danlos tuvieron afectaciones con los fosfolípidos plaquetarios. La hipermovilidad articular estuvo asociada a la combinación difosfato de adenosina (ADP)-epinefrina y el Ehlers-Danlos a la combinación ADP-epinefrina-colágeno-fosfolípidos. Conclusiones: Los pacientes con hipermovilidad articular mostraron asociación a defectos de liberación de gránulos con agonistas como el ADP-epinefrina y los Ehlers-Danlos con la disponibilidad de los fosfolípidos, relacionados con el cambio de forma plaquetaria. Este resultado puede ser una herramienta para conocer el endofenotipo funcional plaquetario como elemento diferencial en los trastornos de la fibra colágena(AU)

Introduction: Platelets contribute to hemostasis and inherited or acquired interruption; in its biochemical processes it can alter platelet function. These aggregation disorders have been associated with genetic diseases with connective tissue involvement such as Ehlers-Danlos syndrome, whose differential diagnosis with the spectrum of joint hypermobility is clinically and molecularly difficult. These entities with involvement of the collagen fibers and different clinical repercussions require differentials in their clinical diagnosis. Methods: 353 medical records of patients attended in the Genetics service of the William Soler Pediatric Hospital from September 2009 to 2012, with a diagnosis of joint hypermobility by Beighton and Ehlers-Danlos criteria according to Villefranche (1997) were reviewed. Patients aged 5-18 years were included with documented results of the platelet aggregation study, assessed by specialists in hematology. Results: Platelet aggregation disorders were found in 79 of 86 patients (92 percent). In 7 cases with hypermobility of 65 with this diagnosis (10 percent), the results were negative. The 21 with Ehlers-Danlos syndrome had affectations with platelet phospholipids. Joint hypermobility was associated with the combination adenosine diphosphate (ADP) -epinephrine and the Ehlers-Danlos with the combination ADP-epinephrine-collagen-phospholipids. Conclusions: Patients with joint hypermobility showed an association to granule release defects with agonists such as ADP-epinephrine and Ehlers-Danlos with the availability of phospholipids, related to platelet shape change. This result can be a tool to know the platelet functional endophenotype as a differential element in collagen fiber disorders(AU)

Rare Cases of PLOD1-Related Kyphoscoliotic Ehlers-Danlos Syndrome in a Korean Family Identified by Next Generation Sequencing

Kyphoscoliotic Ehlers-Danlos syndrome (kEDS) is an autosomal recessive connective tissue disorder characterized by muscular hypotonia, hyperextensible skin, skin fragility, joint hypermobility, and progressive kyphoscoliosis. The disorder results from a deficiency of the enzyme collagen lysyl hydroxylase 1 due to mutations in the gene PLOD1. We describe the rare cases of kEDS in Korean siblings with two novel compound heterozygous variants, c.926_934del (p.Leu309_Leu311del) and c.2170_2172del (p.Phe724del) in the PLOD1 gene. They had congenital hypotonia, joint laxity, skin hyperextensibility, Marfanoid habitus, high myopia and atrophic scarring. The younger sibling had an early-onset progressive kyphoscoliosis, while the older sibling showed mild scoliosis during childhood. Intrafamilial variability of the clinical severity and age of kyphoscoliosis onset observed in our cases.

Hipermovilidad articular y Síndrome de Ehlers-Danlos: consideraciones desde el cuidado en enfermería

Los desórdenes del espectro hipermóvil y síndrome de Ehlers-Danlos (HSD y EDS por sus siglas en inglés) son enfermedades crónicas, consideradas extrañas y que afectan la calidad de vida de estos pacientes. Según estudios internacionales, su prevalencia mundial se encuentra entre el 2 al 57 % de la población, presentando, según la etapa de vida, manifestaciones clínicas variadas. Además, pueden ocurrir exacerbaciones de otras condiciones asociadas, por lo que se torna difícil diagnosticar y se generan múltiples consultas en los distintos niveles de atención. En consecuencia, este escrito reflexiona respecto a la importancia del rol profesional de enfermería en la gestión del cuidado de niños y adultos que viven con este problema de salud, mediante una revisión de publicaciones actualizadas en torno a HSD y EDS. Se enfatiza sobre cómo desde el cuidado de enfermería se puede acompañar a las personas con esta condición. Se concluye que es primordial tomar conciencia de la existencia de esta enfermedad de forma interdisciplinaria, para aportar en la pesquisa, el manejo y cuidado de las personas afectadas.

SUMMARY Hypermobile spectrum disorders and Ehlers-Danlos syndrome (HSD and EDS) are chronic diseases, considered unusual and affecting the quality of life of these patients. According to international studies, its prevalence worldwide is between 2 to 57% of the population and presenting, depending on the stage of life, varied clinical manifestations. Also, exacerbations of other associated conditions may occur, which makes it difficult to diagnose, generating several consults at the different levels of care. Consequently, this paper reflects on the importance of the nurse professional role in managing the care of children and adults living with this health problem, through a review of updated publications on HSD and EDS. Emphasis is placed on how nursing care can accompany people with this condition. It is concluded that it is essential to be aware of the existence of this pathology in an interdisciplinary way to contribute in the research, the management and care of the affected people.

Síndrome de Ehlers-Danlos hipermóvel: um relato de caso / Hypermobile Ehlers-Danlos syndrome: a case report

A síndrome de Ehlers-Danlos é estabelecida por distúrbios hereditários do tecido conjuntivo que tem como manifestações principais a hipermobilidade articular, a hiperextensibilidade da pele e a fragilidade de tecidos, como articulações, ligamentos, pele, vasos sanguíneos e órgãos internos. São reconhecidos 13 subtipos, de acordo com Classificação Internacional de 2017. Dentre estes, abordamos o hipermóvel, cujo diagnóstico é eminentemente clínico, com manifestações sistêmicas distintas. Esse artigo refere-se ao caso de uma paciente diagnosticada com síndrome de Ehlers-Danlos hipermóvel, tendo como intuito a atualização acerca dos novos critérios diagnósticos, assim como o diagnóstico precoce de tal raropatia.

Ehlers-Danlos syndrome is established through hereditary disorders of connective tissue, and has as its manifestations: joint hypermobility, skin hyperextensibility, and fragility of tissues such as joints, ligaments, skin, blood vessels, and internal organs. Thirteen subtypes have been recognized according to the 2017 International Classification. Among these, the hypermobile type, the diagnosis of which is eminently clinical, with distinct systemic manifestations, will be addressed. This article refers to the case of a patient diagnosed with hypermobile Ehlers-Danlos syndrome, with the objective of updating the new diagnostic criteria, as well as the early diagnosis of such a rare disease.

Sindrome de Ehlers-Danlos cifoescoliótico-FKBP14 en una paciente adolescente: primer reporte de caso colombiano / FKBP14 kyphoscoliotic Ehlers-Danlos Syndrome in adolescent patient: the first Colombian report

El síndrome de Ehlers-Danlos es un conjunto de trastornos hereditarios del tejido conectivo, clínica y genéticamente heterogéneos, caracterizados por hiperextensibilidad cutánea, pobre cicatrización, hipermovilidad articular y friabilidad tisular. Desde 1997, se han reportado variantes poco frecuentes del síndrome, entre las cuales se incluye el de tipo cifoescoliótico, causado por mutaciones en el gen PLOD1, caracterizado por hipotonía muscular grave al nacer, cifoescoliosis grave progresiva, osteopenia, ojos frágiles y fragilidad vascular. También ha sido descrita una rara variante recesiva que compromete el gen FKBP14, con hallazgos clínicos adicionales, que incluyen retardo del desarrollo psicomotor, miopatía, hipoacusia y una proporción normal de lisil-piridinolina a hidroxilisil-piridinolina en la orina. Se presenta el primer caso de una paciente colombiana con una mutación FKBP14 c.362dupC, caracterizada por hipotonía generalizada, retardo en el desarrollo de los hitos motores gruesos, hipoacusia, cifoescoliosis progresiva temprana, hipermovilidad articular y deformidades en los pies.

Ehlers-Danlos syndrome (EDS) is a group of clinically and genetically heterogeneous inherited connective tissue disorders, characterized by skin hyperextensibility, poor wound healing, joint hypermobility and tissue friability. Since 1997 a new spectrum of novel rare EDS-variants has been described, among which is included the EDS kyphoscoliotic type, characterized by severe muscular hypotonia at birth, severe progressive kyphoscoliosis, osteopenia, fragile eyeballs and vascular fragility. This EDS variant is caused by mutations in the PLOD1 gene; however, a rare recessive variant that compromises the FKBP14 gene has been reported, with additional clinical findings that includes gross motor developmental delay, myopathy, hearing impairment and a normal ratio of lysyl pyridinoline to hydroxylysyl pyridinoline in urine. We report the first Colombian patient with a FKBP14 c.362dupC mutation, with clinical features that include generalized hypotonia, delayed gross motor milestones, hearing loss, early-onset progressive kyphoscoliosis, joint hypermobility and foot deformities.

Spontaneous perforation of small intestine followed by rupture of the cystic artery: the natural history of Vascular Ehlers-Danlos Syndrome

Vascular Ehlers-Danlos Syndrome (VEDS) is a rare autosomal dominant disorder caused by mutations in the COL3A1 or COL1A1 genes. Its mortality is secondary to sudden and spontaneous rupture of arteries or hollow organs. The genotype influences the distribution of arterial pathology with aneurysms of intra-abdominal visceral arteries being relatively uncommon. We describe the case of a young man with probable VEDS who died of a spontaneous rupture and dissection of the cystic artery. The patient initially presented with abdominal pain due to an unrecognized spontaneous perforation of the small intestine complicated by sepsis. We postulate that inflammatory mediators may have triggered the arterial rupture due to remodeling and weakening of vessel walls. The phenotype of the patient's vascular damage included bilateral spontaneous carotid-cavernous sinus fistulae and dissection with pseudoaneurysm formation of large- and medium-sized arteries, predominantly the abdominal aorta and its branches. The autopsy uncovered a long history of vascular events that may have been asymptomatic. These findings along with a positive family history supported the VEDS diagnosis. Loeys-Dietz, Marfan, and familial thoracic aortic aneurysm and dissection syndromes were ruled out based on the absence of arterial tortuosity, eye abnormalities, bone overgrowth, and the distribution of vascular damage among other features. Interestingly, microscopic examination of the hippocampus revealed a focus of neuronal heterotopia, commonly associated with epilepsy; however, the patient had no history of seizures. The natural course of VEDS involves the rupture and dissection of arteries that, if unrecognized, can lead to a rapid death after bleeding into free spaces.

Ehlers-Danlos syndrome VIII with novel C1R variant accompanying white matter changes

Ehlers-Danlos syndrome (EDS) VIII is an autosomal dominant inherited connective tissue disorder characterized by intractable periodontal inflammation, absence of gingiva, pretibial plaques, skin hyperextensibility, joint hypermobility, and tissue fragility with onset in the childhood or adolescence. In a recent report, heterozygous variants of the C1R or C1S related to the classical complement pathway were identified in families with history of EDS VIII. The current report describes a Korean 34-year-old female carrying a novel missense variant of C1R c.925T>G (p.Cys309Gly) and exhibiting early severe periodontitis, skin fragility, and joint hypermobility. The patient also had frontal, parietal, and temporal white matter brain lesions without definite vascular abnormalities on brain magnetic resonance imaging, which have not been surveyed meticulously in EDS VIII. Considering the genetic alteration of classic complement pathways in this condition, it is necessary to carefully observe multisystemic inflammation processes such as changes in brain white matter.

Resistance to local anesthesia in people with the Ehlers-Danlos Syndromes presenting for dental surgery

BACKGROUND: People with the Ehlers-Danlos Syndromes (EDS), a group of heritable disorders of connective tissue, often report experiencing dental procedure pain despite local anesthetic (LA) use. Clinicians have been uncertain how to interpret this apparent LA resistance, as comparison of EDS and non-EDS patient experience is limited to anecdotal evidence and small case series. The primary goal of this hypothesis-generating study was to investigate the recalled adequacy of pain prevention with LA administered during dental procedures in a large cohort of people with and without EDS. A secondary exploratory aim asked people with EDS to recall comparative LA experiences. METHODS: We administered an online survey through various social media platforms to people with EDS and their friends without EDS, asking about past dental procedures, LA exposures, and the adequacy of procedure pain prevention. Among EDS respondents who both received LA and recalled the specific LA used, we compared agent-specific pain prevention for lidocaine, procaine, bupivacaine, mepivacaine, and articaine. RESULTS: Among the 980 EDS respondents who had undergone a dental procedure LA, 88% (n = 860) recalled inadequate pain prevention. Among 249 non EDS respondents only 33% (n = 83) recalled inadequate pain prevention (P < 0.001 compared to EDS respondents). The agent with the highest EDS-respondent reported success rate was articaine (30%), followed by bupivacaine (25%), and mepivacaine (22%). CONCLUSIONS: EDS survey respondents reported nearly three times the rate of LA non-response compared to non-EDS respondents, suggesting that LAs were less effective in preventing their pain associated with routine office dental procedures.

Treatment of the wide open wound in the Ehlers-Danlos syndrome

Ehlers-Danlos syndrome (EDS) is an inherited disorder of collagen biosynthesis and structure, characterized by skin hyperextensibility, joint hypermobility, aberrant scars, and tissue friability. Besides the skin, skeleton (joint) and vessels, other organs such as the eyes and the intestine can be affected in this syndrome. Accordingly, interdisciplinary cooperation is necessary for a successful treatment. Three basic surgical problems are arising due to an EDS: decreased the strength of the tissue causes making the wound dehiscence, increased bleeding tendency due to the blood vessel fragility, and delayed wound healing period. Surgery patients with an EDS require an experienced surgeon in treating EDS patients; the treatment process requires careful tissue handling and a long postoperative care. A surgeon should also recognize whether the patient shows a resistance to local anesthetics and a high risk of hematoma formation. This report describes a patient with a wide open wound on the foot dorsum and delayed wound healing after the primary approximation of the wound margins.

Falla o resistencia en la anestesia espinal para cesárea / Failure or resistance in spinal anesthesia for cesarean section

Introducción: La anestesia regional es la más empleada en la cesárea obstétrica. En particular, el uso de la anestesia intratecal tiene sus ventajas. Aunque la tasa de falla es baja, la aparición de este evento genera dificultades que merecen atención. Objetivo: Describir la conducta anestésica en una paciente obstétrica en la que falla la anestesia regional intratecal. Caso clínico: Paciente femenina, de 20 años a la que se le administró anestesia intratecal por el especialista. No hubo errores en la punción lumbar, esta se realizó con trócar 25 punta Whitacre. No se constató bloqueo sensitivo, motor ni simpático, por lo que se realizó anestesia general endotraqueal, la cual transcurrió sin dificultades. En el posoperatorio inmediato se observa hiperlaxitud articular lo que llevó a sospechar el diagnóstico. Este fue positivo conjuntamente con el servicio de Neurología, se determinó Síndrome de Ehlers danlos tipo III. Conclusiones: El índice de falla es muy bajo en anestesia suaracnoidea pero si se presenta un paciente de este tipo, debe descartarse por completo. Existen pocos casos documentados de resistencia a la anestesia local; pero si así fuera, debe estudiarse exhaustivamente para buscar estrategias que permitan un acto anestésico óptimo(AU)

Introduction: Regional anesthesia is the most used in obstetric caesarean section. In particular, the use of intrathecal anesthesia has its advantages. Although the failure rate is low, the onset of this event generates difficulties that deserve attention. Objective: To describe the anesthetic management in an obstetric patient with failure of regional intrathecal anesthesia. Clinical case: Female patient, aged 20 years, who was administered intrathecal anesthesia by the specialist. There were no errors in the lumbar puncture, this was done with a trocar 25 of Whitacre tip. No sensory, motor or sympathetic block was observed, so general endotracheal anesthesia was performed, which went on smoothly. In the immediate postoperative period, joint hypermobility was observed, leading to suspicion of the diagnosis. This was positive in conjunction with the Neurology service, Ehlers-Danlos syndrome type 3 was determined. Conclusions: The failure rate is very low for subarachnoid anesthesia. However, for a patient of this type, it should be completely ruled out. There are few documented cases of resistance to local anesthesia. If it were the case, it should be studied exhaustively to look for strategies that allow an optimal anesthetic management(AU)

Sospecha diagnóstica de síndrome de Ehlers Danlos tipo vascular: reporte de un caso y revisión de literatura / Suspected vascular ehlers danlos syndrome: case report

Ehlers Danlos Syndrome comprises a heterogeneous group of genetic disorders of the connective tissue, due to defects in collagen or its modifying enzymes. We report a 21 years old male presenting with translucent skin revealing the subcutaneous venous pattern. He had a thin face, large-appearing eyes, thin lips, thin nose, joint hypermotility and history of hip dysplasia. A vascular Ehlers Danlos Syndrome was suspected. However, the genetic study to confirm the diagnosis was not done.

Niccolò paganini: análisis médico e histórico de un gran artista / Niccolò paganini: medical and historical analysis of a great artist

La figura de Paganini es un hito histórico, de una interpretación musical excelsa y un ejemplo distintivo de los misterios ocultos de la vida, de músicos excepcionales. Hemos tratado de dilucidar los aspectos médicos más relevantes, del mito creado alrededor de la vida del violinista, con el propósito de entender claramente la leyenda de este talentoso artista.

Paganini's name is a clear historical trademark of outstanding musical performance and a very distinct example of the mysteries of the occult surrounding the lives of exceptional musicians. We have delved into the medical aspects and the myth created around the violinist's life in order to shed light on the legend of this wondrous artist.

Temporary Abdominal Closure after Surgical Repair of the Iliac Artery Rupture due to Vascular Type Ehlers-Danlos Syndrome / 日本心臓血管外科学会雑誌

A 39-year-old man was found to have left iliac artery rupture, and was transferred to our department. Emergency surgical repair was done, however, his intra- and postoperative condition precluded primary abdominal closure. On the 8th postoperative day, temporary abdominal closure (TAC) was performed using Composix Mesh TM and negative pressure wound therapy (NPWT). On the 19th day after the first surgery, an emergency reoperation was needed because of the rupture of the common hepatic artery aneurysm, of which there was no finding on admission. After the reoperation of the hepatic artery aneurysm, TAC was again performed using new Composix Mesh. On the 43rd day after the first surgery, the abdominal wall reconstruction without Composix Mesh was done using components separation and the anterior rectus abdominis sheath turnover flap method. On the 106th day after the first surgery, he had recovered well and was discharged. The genetic testing revealed COL3A1 mutation, which is specific for vascular type Ehlers-Danlos syndrome. When long-term open abdominal management is necessary after the abdominal aortic surgery, TAC with Composix Mesh and NPWT may be a useful alternative. Artery rupture in young people is a finding that should be considered suspicious for vascular type Ehlers-Danlos syndrome, which is difficult to treat.

Vascular Ehlers-Danlos Syndrome (EDS) causes fragility of the blood vessels, skin, and hollow organs, and the most common clinical feature is vascular rupture. We report a surgical case of a spontaneous ruptured dissection of the left common iliac artery (CIA) in a patient with vascular EDS. A 27-year-old man with documented vascular EDS with a mutation of the collagen type III alpha-1 [COL3A1] gene, presented with acute left lower abdominal pain. The enhanced computed tomography (CT) scan revealed a ruptured dissection of the left CIA with extravasation, and left iliopsoas hematoma. The enhanced CT performed 1 month previously showed no arterial aneurysm. The left CIA was anastomosed end-to-end using a 7 mm heparin-bonded polytetrafluorethylene (PTFE) graft (Fusion, MAQUET Cardiovascular LLC, USA). A PTFE graft was anastmosed end-to-side to the left external iliac artery (EIA). The distal side of the CIA was closed. The postoperative enhanced CT showed aneurysmal formation in the right inferior gluteal artery. The follow-up CT showed enlargement of the left EIA (from 7.5 to 12 mm in a diameter), and aneurysm formation in the proper hepatic artery. Therefore, a close follow-up based on noninvasive imagings is mandatory to detect life-threatening vascular complecations in patients with vascular EDS.
