ABSTRACT

ABSTRACT Objective: To present a case of bilateral gynecomastia in a prepubertal boy with autism spectrum disorder, diagnosed with myotonic dystrophy type 1. Case description: A 12-year-old boy with autism spectrum disorder presented at a follow-up visit with bilateral breast growth. There was a family history of gynecomastia, cataracts at a young age, puberty delay, and myotonic dystrophy type 1. The physical examination showed that he had bilateral gynecomastia with external genitalia Tanner stage 1. Neurologic examination was regular, without demonstrable myotonia. The analytical study revealed increased estradiol levels and estradiol/testosterone ratio. After excluding endocrine diseases, the molecular study of the dystrophia myotonica protein kinase gene confirmed the diagnosis of myotonic dystrophy type 1. Comments: A diagnosis of prepubertal gynecomastia should include an investigation for possible underlying diseases. This case report highlights the importance of considering the diagnosis of myotonic dystrophy type 1 in the presence of endocrine and neurodevelopmental manifestations.


RESUMO Objetivo: Apresentar o caso de um adolescente pré-púbere com ginecomastia bilateral e transtorno do espectro autista, diagnosticado com distrofia miotônica tipo 1. Descrição do caso: Adolescente do sexo masculino de 12 anos, com transtorno do espectro autista, observado em consulta de seguimento por crescimento mamário bilateral. O paciente tinha antecedentes familiares de ginecomastia, catarata em idade jovem, atraso pubertário e distrofia miotônica tipo 1. À observação física, apresentava ginecomastia bilateral estádio 1 de Tanner. O exame neurológico era normal, sem miotonia aparente. O estudo analítico mostrou níveis elevados de estradiol e da relação estradiol/testosterona. Após exclusão de causas endócrinas, o estudo molecular do gene DMPK confirmou o diagnóstico de distrofia miotônica tipo 1. Comentários: Perante um quadro de ginecomastia pré-púbere, deve-se excluir doenças subjacentes. Este caso reforça a importância de considerar o diagnóstico de distrofia miotônica tipo 1 na presença de manifestações endócrinas e do neurodesenvolvimento.

ABSTRACT

Abstract Background and objectives: Ultrasound-guided upper limb blocks may provide great benefits to patients with serious diseases. Patients with Steinert's disease have muscle weakness and risk of triggering myotony or malignant hyperthermia due to the use of anesthetic agents and surgical stress. The objective of this report was to demonstrate a viable alternative for clavicle fracture surgery with upper trunk and supraclavicular nerve block, thus reducing the spread of local anesthetic to the phrenic nerve in a patient with muscular dystrophy. Case report: A 53-year-old male patient with Steinert's disease, associated with dyspnea, hoarseness and dysphagia, referred to the surgical theater for osteosynthesis of clavicle fracture. Upper limb (1 mL 0.75% ropivacaine) and supraclavicular nerve block (1 mL 0.75% ropivacaine in each branch) were combined with venous anesthesia with propofol under laryngeal mask (infusion pump target of 4 mcg.mL-1). Upon awakening, the patient had no pain or respiratory complaints. He was transferred to the ICU for immediate postoperative follow-up with discharge from this unit after 24 h without complications. Conclusions: The superior trunk and cervical plexus block associated with venous anesthesia under laryngeal mask, without the use of opioids, proved to be adequate in the case of a patient with clavicle fracture and Steinert's disease. With the use of ultrasonography in regional anesthesia it is possible to perform increasingly selective blocks, thus allowing greater security for the anesthetic-surgical procedure and lower morbidity for the patient.


Resumo Justificativa e objetivos: Bloqueios seletivos dos membros superiores guiados por ultrassom podem trazer grandes benefícios em pacientes portadores de doenças graves. Pacientes portadores da doença de Steinert apresentam fraqueza muscular e riscos de desencadear miotonia ou hipertermia maligna devido ao uso de agentes anestésicos e ao estresse cirúrgico. O objetivo deste relato foi mostrar uma opção viável para a cirurgia de fratura de clavícula com bloqueio do tronco superior e nervo supraclavicular, diminui-se assim a dispersão do anestésico local para o nervo frênico em paciente com distrofia muscular. Relato de caso: Paciente do sexo masculino, 53 anos, portador de doença de Steinert, associada a dispneia, rouquidão e disfagia. Encaminhado ao bloco cirúrgico para osteossíntese de fratura de clavícula. Feito bloqueio de tronco superior (1 mL ropivacaína a 0,75%) e de nervo supraclavicular (1 mL de ropivacaína 0,75 em cada ramificação) associado à anestesia venosa com propofol sob máscara laríngea (alvo de 4 mcg.mL-1 em bomba de infusão). Ao despertar, o paciente apresentava-se sem dor ou queixas respiratórias. Admitido em CTI para acompanhamento do pós-operatório imediato com alta dessa unidade após 24 horas sem intercorrências. Conclusões: O bloqueio do tronco superior e do plexo cervical associado à anestesia venosa sob máscara laríngea, sem uso de opioides, mostrou-se adequado no caso de fratura da clavícula em paciente com doença de Steinert. Com o uso da ultrassonografia em anestesia regional é possível fazer bloqueios cada vez mais seletivos e possibilitar assim maior segurança para o procedimento anestésico-cirúrgico e menor morbidade para o paciente.

ABSTRACT

Introducción: la enfermedad de Steinert es una enfermedad neuromuscular crónica y progresiva de carácter autosómico dominante. Debido a que puede afectar a los músculos respiratorios, los pacientes se benefician de distintas técnicas de fisioterapia con el fin de evitar complicaciones. Caso clínico: paciente con enfermedad de Steinert que fue tratada en un hospital público de la provincia de Buenos Aires durante un cuadro de insuficiencia respiratoria aguda, de manera no invasiva. Comentarios: esta experiencia muestra que estos pacientes pueden ser tratados de manera no invasiva, fuera de la unidad de cuidados intensivos, y ser controlados ambulatoriamente luego de su egreso pudiendo reinsertarse en la comunidad. Asimismo, cabe destacar que esto fue posible en un hospital público, dentro de un contexto institucional y socioeconómico desfavorable(AU)


Introduction: Steinert's disease is a chronic and progressive autosomal dominant neuromuscular disease. Because this disease can affect respiratory muscles, these patients benefit from different physiotherapy techniques in order to avoid complications. Case presentation: patient with Steinert's disease who was treated in a Public Hospital of the Province of Buenos Aires during an acute respiratory failure with non-invasive way. Comments: This experience shows that these patients can be treated non-invasively, outside the intensive care unit, and be controlled outpatient after discharge, being able to be reinserted in the community. It should also be noted that this was possible in a public hospital, within an unfavorable institutional and socio-economic context(AU)

ABSTRACT

ABSTRACT Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10 mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.


RESUMO A doença de Steinert é uma desordem intrínseca do músculo com manifestações multissistêmicas. A miotonia pode afetar qualquer grupo muscular e é provocada por vários fatores e medicamentos usados em anestesia geral, como hipnóticos, sedativos e opiáceos. Embora alguns autores recomendem o uso de anestesia regional ou anestesia combinada com opiáceos em doses baixas, a técnica anestésica mais segura ainda precisa ser estabelecida. Administramos raquianestesia contínua em um paciente com doença de Steinert submetido à colecistectomia laparoscópica, com 10 mg de bupivacaína a 0,5%, e fornecemos suporte ventilatório no período perioperatório. A raquianestesia contínua foi usada com segurança em pacientes com doença de Steinert, mas não foi relatada em colecistectomia laparoscópica. Relatamos a raquianestesia contínua como uma técnica adequada para a colecistectomia laparoscópica e particularmente valiosa em pacientes com doença de Steinert.

ABSTRACT

Introducción: la distrofia miotónica de Steinert, es una enfermedad multisistémica, autosómica dominante de penetrancia variable, causada por la expansión del triplete CTG, en el gen que codifica para la proteína kinasa de la distrofia miotónica en el cromosoma 19ql3. Se caracteriza por un fenómeno de anticipación, producto del cual su expresión es mayor en generaciones sucesivas y correlaciona con la talla de la expansión. Desde el punto de vista clínico se manifiesta por desórdenes multisistémicos asociados a disfunción muscular, siendo sus características más frecuentes la debilidad muscular lenta pero progresiva, atrofia muscular y el fenómeno miotónico. Presentación del caso: paciente de 52 años de edad que fue visitado en su hogar durante el estudio de personas con discapacidad realizado en el cantón Quito, ya que tenía el diagnóstico de Distrofia Miotónica de Steinert a partir del cual se examina al resto de la familia y se encuentran signos y síntomas de la enfermedad en 3 familiares del propósito. Conclusiones: no existe un sistema de asesoramiento genético en la comunidad que permita a la familia y al paciente con Distrofia Miotónica de Steinert la realización tanto de un seguimiento de su enfermedad como el conocimiento del nivel de recurrencia para este tipo de trastorno.


Introduction: Steinert's Myotonic Dystrophy is a multiple-system, autosomal dominant of variable penetrance disease caused by an expansion of the cytosine-thymine-guanine (CTG) triplet, in the gene which codes for myotonic dystrophy protein kinase in chromosome19q13. It is characterized by a phenomenon known as anticipation, thus its expression is greater in successive generations and it correlates with the size of expansion. From the clinical view point it is expressed by multiple-system disorders associated with a muscle-dysfunction, the most frequent characteristics are muscle weakness it progresses slowly, muscle atrophy and myotonic phenomenon. Case report: a 52-year old patient who was visited in his home during the study that involved disabled people in Canton, Quito, the patient suffered from Steinert's Myotonic Dystrophy,the the rest members of the family were as well examined; signs and symptoms of the disease were found in three other family members. Conclusions: the study demonstrated the non-existence of a system to perform genetic counselling in the community, which would permit the follow-up of the families and patients suffering from Steinert's Myotonic Dystrophy, this difficulty also impedes the acquisition of knowledge regarding the level of recurrence for this type of genetic disorder.

ABSTRACT

The aim was to analyze the characteristics of the temporomandibular joint (TMJ) in a group of adult patients suffering from Steinert's muscular dystrophy (DM1). This study included 42 adult patients aged between 21 and 69 years (mean = 38.7619; SD = 12.74) who were diagnosed for DM1. Study was conducted using the MRI of right and left TMJ sagittal images taken in maximum intercuspidation position and maximum oral opening without pain, and the following were discussed: a) the quality of the cortical bone in the mandibular fossa, tuberosity, and mandibular head; b) the relationship of mandibular head­disc­joint tuberosity in maximum intercuspidation position; c) the anatomical shape of the articular disc. All patients showed abnormalities in the shape and surface of the cortical bone in the mandibularfossa, tuberosity, and the mandibular head. With regard to the relationship of the mandibular head in the mandibular fossa, 41% was found in the region 2B, 29% in 1B, 18% in 1A, 9% in 2C, and 3% in 2A of the TMJ. About 49% of the disc in maximum intercuspidation position was found on the mandibular head, 26% were anterior displaced, 14% had anterior dislocations, 38% had alterations in the form of disc, and 30% had preserved the anatomical shape. However, 98% of the discs showed hyposignal in T1 and T2. Using MRI, the decrease in the muscle activity in patients with DM1 was found to generate degenerative changes visible in the TMJ.


El objetivo de este estudio, fue analizar las características de la articulación temporomandibular (ATM) en un grupo de pacientes adultos portadores de distrofia muscular de Steinert (DM1). Fueron evaluados 42 pacientes adultos, con edades entre 21 y 69 años (Media=38,7619; DE=12,74) diagnosticados con DM1. Se realizó un estudio por RNM de ATM mediante imágenes sagitales de ATM derecha e izquierda en posición de máxima intercuspidación (MIC) y apertura máxima sin dolor, y se analizaron a) la calidad de las corticales de la fosa mandibular, tuberosidad y cabeza mandibular, b) la relación cabeza mandibular- disco- tuberosidad articular en MIC, c) la forma anatómica del disco articular. Todos los pacientes presentaron alteraciones en la forma y superficie de las corticales de la fosa mandibular, tuberosidad articular y cabeza mandibular. Con respecto a la relación de la CM en la FM, el 41% se encontró en la región 2B, el 29% 1B, 18% 1A, 9% 2A y 3% 2C de la ATM. El 49% de los discos en MIC se encontraron sobre la cabeza mandibular, 26% estaban desplazados anteriormente, 14% presentaron un dislocamiento anterior. El 38% presentó alteraciones de la forma del disco y 30% presentaron conservada la forma anatómica. El 98% de los discos presentaron hiposeñal en T1 y T2. La disminución de la actividad muscular en los pacientes con DMS genera cambios degenerativos en la ATM visibles con RNM.

ABSTRACT

A distrofia miotônica tipo 1 (DM1 ou doença de Steinert) é uma doença genética com repercussões multissistêmicas, na qual é comum o paciente buscar diversos especialistas antes da suspeição clínica. O envolvimento cardíaco é uma das características principais da evolução da DM1 e explica, em parte, a menor expectativa de vida dos pacientes. Relata-se caso de paciente masculino, 28 anos, com admissão por insuficiência cardíaca descompensada após oito anos de diagnóstico quando apresentou episódio de síncope secundária a bloqueio atrioventricular total. Sob marca-passo definitivo desde então. Discutem-se os aspectos etiológicos, fisiopatológicos e clínicos da DM1 com ênfase nas manifestações cardiovasculares.


Myotonic Dystrophy type 1 (MD1 or Steinert's Disease) is a genetic syndrome with multissistemic repercussions, and it is usual to the patient to seek for several specialists before clinical suspicion. It is related a case of a 28 years old male patient admitted with congestive heart failure. MD1 has been diagnosed eight years before. At the time of the diagnosis, he presented syncope secondary to Complete Atrioventricular Block. From that time on, he had a permanent pacemaker implanted. Etiological, pathophysiological and clinical aspects of MD1 with emphasis on cardiovascular manifestations are discussed.

ABSTRACT

Type I myotonic dystrophy or Steinert's disease (DM1, OMIM 160900), is an autosomal dominant mulsystem disease of variable expresión caused by a (CTG)n, expansion mutation in the gene encoding for the myotonic dystrophy protein kinase (DMPK) in 19ql3. The disease is characterized by a phenomenon of anticipation, resulting in a more severe expression of the disease in successive generations, in correlation with the size of the triplet expansion. The congenital form of the disease, ussually of maternal transmisión, may cause polyhidramnios, foetal or neonatal death, or a sever neonatal floppy infant syndrome charaterized by facial diplegia, dysphagia, respiratory distress syndrome and a variable degree of mental retardation in 60 percent of the cases. The aim of this report is to describe a DM1 affecting a 35 years old woman and her fetus of 28 weeks of gestation at the moment of diagnosis. We describe the evolution of the pregnancy and her neonate, we discuss the reciprocal influence between pregnancy and the disease, enhacing the antenatal and neonatal complications.


La distrofia miotónica de Steinert o tipo I (DM1, OMIM 160900), es una enfermedad multisistémica, autosómica dominante de penetrancia variable, causada por la expansión del tupíete (CTG)n, en el gen que codifica para la proteína kinasa de la distrofia miotónica (DMPK) en el cromosoma 19ql3. La enfermedad se caracteriza por un fenómeno de anticipación, producto del cual su expresión es mayor en generaciones sucesivas y correlaciona con la talla de la expansión. La forma congénita de la enfermedad, habitualmente de transmisión materna puede producir polthidramnios, muerte fetal o neonatal o un síndrome hipotónico neonatal severo con diplegia facial, disfagia, distress respiratorio y retardo mental de grado variable en un 60 por ciento de los casos. El presente reporte tiene por objeto comunicar un caso de DM1 en una mujer de 35 años y en su feto de 28 semanas de gestación al momento del diagnóstico. Describimos la evolución del embarazo y del neonato, se discute la influencia recíproca entre la enfermedad y el embarazo, con énfasis en las complicaciones antenatales y neonatales.
