ABSTRACT

Introducción: La miocardiopatía hipertrófica es una enfermedad derivada de una alteración genética autosómica dominante que produce un aumento de la masa del ventrículo izquierdo, obstructiva o no. Es la principal causa de muerte súbita en adultos jóvenes. Objetivo: Mostrar la prevalencia de la miocardiopatía hipertrófica en la práctica del Cardiocentro Pediátrico "William Soler" y sus formas de presentación. Métodos: Estudio observacional longitudinal retrospectivo de serie de casos. Se resumieron variables demográficas y clínicas en los ingresos realizados durante 10 años de los pacientes con diagnóstico de miocardiopatía hipertrófica y se analizaron según correspondieran con pruebas para variables cualitativas y cuantitativas. Resultados: Se identificaron 21 pacientes; 12 con características obstructivas y 9 no obstructivas. No hubo predominio de sexo. La media de edad de diagnóstico y de debut clínico de los pacientes con enfermedad obstructiva fue significativamente menor que las edades de los pacientes sin obstrucción del tracto de salida izquierdo. El diagnóstico fue posible en más de 50 por ciento de los casos por sospecha por soplo o por pesquisa. El tratamiento quirúrgico permitió la reducción significativa del gradiente en el tracto de salida izquierdo. El propranolol fue el betabloqueador más usado acorde a consensos internacionales. No hubo fallecidos en la serie estudiada. Conclusiones: La miocardiopatía hipertrófica tiene una baja prevalencia en la práctica cardiopediátrica. Los síntomas tempranos se corresponden con la variedad obstructiva. Su diagnóstico temprano y el tratamiento específico, permite garantizar mejor calidad y expectativa de vida a los portadores de esta afección(AU)


Introduction: Hypertrophic cardiomyopathy is a disease derived from autosomal dominant genetic alteration that causes an increase in the mass of the left ventricle, and can be obstructive or not. It is the leading cause of sudden death in young adults. Objective: Show the prevalence of hypertrophic cardiomyopathy and its forms of presentation in the practice of the "William Soler" Pediatric Cardiocenter. Methods: Retrospective, observational, longitudinal study of a case series. Demographic and clinical variables were summarized in the admissions made during 10 years of patients diagnosed with hypertrophic cardiomyopathy whom were analyzed as appropriate with qualitative and quantitative variable testing. Results: 21 patients were identified; 12 with obstructive characteristics and 9 with non-obstructive ones. There was no predominance of sex. The average diagnostic age and clinical onset of patients with obstructive disease was significantly lower than the ages of patients without obstruction of the left outflow tract. Diagnosis was possible in more than 50 percent of cases by suspicion due to a murmur or by investigation. Surgical treatment allowed a significant reduction in the gradient of the left outflow tract. Propranolol was the most widely used beta-blocker according to international consensus. There were no deaths in the series studied. Conclusions: Hypertrophic cardiomyopathy has a low prevalence in cardiopediatric practice. Early symptoms correspond to the obstructive variety. Early diagnosis and specific treatment ensure better quality and life expectancy for carriers of this condition(AU)

ABSTRACT

La linfangiomatosis pulmonar difusa es una enfermedad rara caracterizada por una marcada proliferación y dilatación de los vasos linfáticos en los pulmones, la pleura y el mediastino. Se desconoce la prevalencia, y la etiología no se comprende completamente.Una niña de 22 meses ingresó por poliserositis, con derrame pericárdico y pleural. Requirió pericardiocentesis y avenamiento pleural, y presentó drenaje de quilo (1,5-4 litros/día) sin respuesta al tratamiento médico (ayuno, nutrición parenteral y octreotide). Se realizó biopsia pulmonar. La anatomía patológica mostró hallazgos compatibles con linfangiomatosis difusa pulmonar. Comenzó tratamiento con sirolimus y propanolol, que disminuyeron las pérdidas por el drenaje pleural a la semana. Presentó buena evolución; suspendió aporte de oxígeno y se retiró el drenaje pleural. Se externó al cuarto mes de internación. El diagnóstico temprano de la linfangiomatosis pulmonar difusa es difícil de lograr, pero permite aplicar terapéuticas que evitan la progresión de enfermedad y disminuir la morbimortalida


Diffuse pulmonary lymphangiomatosis is a rare disease characterized by marked proliferation and dilation of lymphatic vessels in the lungs, pleura, and mediastinum. The prevalence is unknown and the etiology is not fully understood.A 22-month-old girl was admitted for polyserositis, with pericardial and pleural effusion. She required pericardiocentesis and pleural drainage, presenting chyle drainage (1.5-4 liters/day) without response to medical treatment (fasting, parenteral nutrition and octreotide). A lung biopsy was performed. The pathological anatomy showed findings compatible with diffuse pulmonary lymphangiomatosis. Treatment with sirolimus and propanolol began, decreasing losses due to pleural drainage one week after treatment. She progressed well, discontinued oxygen supply and pleural drainage was removed, leaving the patient after the fourth month of hospitalization.Early diagnosis of diffuse pulmonary lymphangiomatosis is difficult to achieve, but it allows the application of therapies that prevent disease progression, reducing morbidity and mortality.

ABSTRACT

El hemangioma hepático es el tumor benigno de hígado más frecuente. Puede ser congénito o infantil, con diferentes evoluciones y complicaciones. La evolución clínica es muy variable, desde pacientes asintomáticos hasta cuadros de gravedad con insuficiencia cardíaca, síndrome de Kasabach-Merritt o síndrome compartimental. El diagnóstico se basa en la historia clínica y los estudios por imágenes, especialmente, la ecografía y el examen doppler en manos experimentadas. Resulta fundamental el diagnóstico diferencial con otras lesiones hepáticas, sobre todo, el hepatoblastoma. En los pacientes sintomáticos, el propranolol surge como primera línea terapéutica con buenos resultados y baja frecuencia de efectos adversos. Se presenta el caso de un recién nacido con hemangioma hepático asociado a síndrome de Kasabach-Merritt, con excelente respuesta y tolerancia al propranolol


Hepatic hemangioma is the most common benign liver tumor. It can be congenital or infantile with different outcomes and complications. The clinical manifestation varies from asymptomatic to severe conditions with heart failure, Kasabach-Merritt syndrome or compartment syndrome. Diagnosis depends on medical history and imaging studies, especially ultrasound and Doppler examination in experienced hands. Differential diagnosis is essential with other hepatic lesions, mainly hepatoblastoma. In symptomatic patients, propranolol emerges as the first line treatment with good results and low frequency of adverse effects. We present the case of a newborn with a hepatic hemangioma and Kasabach-Merritt syndrome with an excellent response and tolerance to propranolol.

ABSTRACT

La enfermedad trofoblástica gestacional (ETG) es una complicación del embarazo poco común. Corresponde a un espectro de lesiones proliferativas del tejido trofoblástico: Mola Hidatiforme (MH) en sus formas parcial y completa, Coriocarcinoma, Tumor Trofoblástico y Tumor Trofoblástico Epiteloide. Los distintos tipos de ETG presentan en común la hipersecreción de gonadotrofina coriónica humana (hCG). La hCG es una hormona glicoproteica con una estructura muy similar a la TSH, por lo cual puede estimular la función tiroidea en condiciones fisiológicas y en algunas condiciones patológicas. La ETG puede cursar con hipertiroidismo, el cual puede variar en intensidad, desde una presentación asintomática con alteración leve de hormonas tiroideas a un cuadro de hipertiroidismo manifiesto. Se presentan 3 casos clínicos de pacientes con ETG, específicamente MH que evolucionaron con tirotoxicosis transitoria. Los casos presentaron un cuadro leve de hipertiroidismo con pocos síntomas asociados. La taquicardia fue el único síntoma en la mayoría de los casos. En todas las pacientes las hormonas tiroideas se normalizaron después del tratamiento de la ETG. Conclusión: Se debe tener presente la posibilidad de hipertiroidismo en toda paciente con ETG. Un alto nivel de sospecha permitirá identificar a aquellas pacientes que cursen con hipertiroidismo, permitiendo así un diagnóstico y tratamiento oportuno.


Gestational trophoblastic disease (GTD) is a rare complication of pregnancy. GTD includes a group of proliferative lesions of trophoblastic tissue: partial and complete hydatidiform mole, choriocarcinoma, epithelioid trophoblastic tumor, and placental site trophoblastic tumor. The different types of GTD have in common the hypersecretion of human chorionic gonadotropin (hCG). HCG is a glycoprotein hormone with a similar structure to TSH. In physiological and pathological conditions hCG can stimulate thyroid function. GTD can present with hyperthyroidism, which can vary in intensity, from an asymptomatic presentation with mild alteration of thyroid hormones to a manifest hyperthyroidism. We present 3 clinical cases of patients with GTD thyrotoxicosis. All cases presented mild hyperthyroidism. Tachycardia was the only symptom in most cases. In all patients thyroid hormones return to normal after treatment of GTD. Conclusion: In patients with GTD the possibility of hyperthyroidism should be kept in mind. A high level of suspicion will allow to identifying patients with hyperthyroidism.

ABSTRACT

Resumen: La Retinopatía del Prematuro (RDP) es una alteración proliferativa de los vasos sanguíneos de la retina inmadura, que afecta principalmente a los recién nacidos de muy bajo peso (RNMBP) y de menor edad gestacional. El objetivo de esta revisión es describir a qué niño se debe efectuar la detección de esta enfermedad y analizar los recientes avances en su tratamiento. La detección de RDP está dirigida principalmente a los RNMBP y a < de 32 semanas de edad gestacional, pero también se ha propuesto un criterio según edad postmenstrual. Además de la fotocoagulación con láser, tratamiento estándar en la actualidad, se han desarrollado nuevas terapias, como los agentes anti factor de crecimiento vas cular endotelial (VEGF), que se han utilizado exitosamente en la retinopatía umbral, especialmente localizada en zona I, con menos efectos adversos y mejores resultados oculares a futuro. que la fo tocoagulación con láser. En los últimos años, se han realizado ensayos clínicos con propranolol oral como tratamiento de la RDP, principalmente en la etapa pre-umbral (etapa 2 o 3 en zona II ó III). Este bloqueador beta-adrenérgico puede prevenir la progresión de la retinopatía en RNMBP de etapa pre- umbral a umbral y/o evitar la necesidad de terapias invasivas, como la fotocoagulación con láser o la administración intravítrea de agentes anti-VEGF. La fotocoagulación con láser continúa siendo el tra tamiento de elección en la RDP. Los agentes anti-VEGF y el propranolol oral, evitarían la progresión de esta patología de etapa pre-umbral a umbral, y podrían complementar el tratamiento de la RDP.


Abstract: Retinopathy of Prematurity (ROP) is a proliferative disorder of the blood vessels of the immature retina, which affects mainly very-low-birth-weight infants (VLBW). The objective of this review is to describe to which infant the screening examination of this disease should be performed and to analy ze the recent advances in the treatment of this disease, which have emerged in the last decade. The detection of this disease is mainly focused on VLBW infants and newborns < 32 weeks of gestational age. In addition to laser photocoagulation, standard treatment today, new therapies have appeared, such as the anti-VEGF agents, which have been successfully used in the threshold ROP, especially located in zone I. This therapy is less harmful than laser photocoagulation and with better ocular results in the future. In recent years, oral propranolol has been used as a treatment for ROP in clinical trials, mainly in the pre-threshold stage (stage 2 or 3 in zone II or III). This drug is a beta-adrenergic blocker that can prevent the progression of retinopathy in pre-threshold to threshold stage and/or avoid the need for invasive therapies, such as laser photocoagulation or intravitreal administration of anti-VEGF agents. Laser photocoagulation continues to be the standard treatment for ROP. New treatments have emerged for ROP, such as anti-VEGF agents and oral propranolol, which could pre vent the progression of this disease from the pre-threshold to the threshold stage.

ABSTRACT

Se realizó un estudio cuasi-experimental de series temporales para evaluar la efectividad del propranolol en el tratamiento de malformaciones vasculares cutáneas en 48 pacientes que asistieron a la consulta del Servicio de Dermatología del Hospital Central Universitario Dr. Antonio María Pineda durante el período febrero-julio 2018. Los resultados muestran que existen diferencias estadísticamente significativas (p <0.05; p0,0001) antes y después del primer mes de tratamiento con propranolol, las cuales se mantiene hasta los seis meses, con respecto al tamaño, color, consistencia y temperatura. Se espera que los resultados sirvan para proponer el uso de propranolol como una opción terapéutica no invasiva en el tratamiento de las malformaciones vasculares cutáneas(AU)


A quasi-experimental study of time series was carried out to evaluate the effectiveness of propranolol in the treatment of cutaneous vascular malformations in 48 patients attending the Dermatology Service of the Hospital Central Universitario Dr. Antonio Maria Pineda during the period February - July 2018. The results show that there are statistically significant differences (p <0.05; p0,0001) before and after treatment with propranolol starting one month post-treatment which are kept until six months, related to size, color, consistency and temperature of lesions. We hope that these results will encourage the use of propranolol as a non-invasive therapeutic option in the treatment of cutaneous vascular malformations(AU)

ABSTRACT

ABSTRACT Objective: To present the outcomes of fixed doses of propranolol tablets for the treatment of hemangiomas. Case description: Two illustrative cases of hemangioma in infant patients younger than six months old are described. Treatments were started in 2010 and 2011 and were monitored until August 2017. Patients were treated with fixed doses, initially calculated based on the upper limit of 3 mg/kg/day and administrated in two daily doses rounded down to the nearest multiple of five milligrams. Dosage was not adjusted to patients' weight gain. The tablets were crushed and then diluted in a maximum amount of 3 mL of water. This procedure was necessary because propranolol was not available in oral solution in 2009, when dosages available in the Brazilian market were 10, 40 and 80 mg. Both patients presented significative improvement in the first 60 days and were in complete remission by the end of the treatment. Comments: It is possible to treat patients with Propranolol 10 mg tablets, even though the dosage is not as precise as when calculated according to patients' weight. The maintenance of a fixed dose, ignoring the patient's progressive weight gains, helps avoiding the rebound effect and decreases complications.


RESUMO Objetivo: Apresentar a experiência com a utilização de propranolol em doses fixas, em forma de comprimido, para o tratamento de hemangiomas. Descrição do caso: Dois casos ilustrativos de portadores de hemangiomas com menos de seis meses de idade são descritos. O início de tratamento ocorreu nos anos de 2010 e 2011 com seguimento até agosto de 2017. Os pacientes foram tratados com doses fixas iniciais calculadas com limite máximo de 3 mg/kg/dia, divididas em duas doses diárias, sempre com quantidades múltiplas de 5 mg. Os comprimidos de 10 mg ou a sua metade eram macerados e diluídos em 3 mL de água. As doses não foram mais alteradas. Esse uso foi decorrente da ausência da forma líquida de propranolol em 2009, quando começamos a utilizar esse tratamento, sendo então apenas disponíveis comprimidos de 10, 40 e 80 mg. Os pacientes obtiveram melhora acentuada nos primeiros 60 dias e remissão completa posteriormente. Comentários: É possível o uso de comprimidos de 10 mg, apesar de resultar numa dose não exata, como a calculada por kg/peso. A manutenção da mesma dose, mesmo com aumento progressivo de peso, pode evitar o efeito rebote e diminuir o índice de complicações.

ABSTRACT

Um dos grandes desafios no atendimento dos pacientes nas unidades de emergência é o tratamento das arritmias ventriculares, principalmente, quando sustentadas e recorrentes, pois são de difícil tratamento e estão associadas à alta mortalidade. O principal mecanismo envolvido na sustentação das taquicardias ventriculares é o mecanismo de reentrada, devido às cicatrizes miocárdicas secundárias a diversas cardiopatias estruturais. A tempestade elétrica pode ser séria quando ocorre em portadores de desfibriladores automáticos, provocando múltiplos choques correspondentes fora do ambiente hospitalar. Nesses casos é necessária a internação hospitalar, onde medidas específicas e escalonadas de tratamento são realizadas, indo desde o manejo clínico até intervenções específicas, como programação de dispositivos eletrônicos, intervenções eletrofisiológicas ou cirúrgicas


One of the biggest challenges in the care of patients in emergency units is the treatment of ventricular arrhythmias, particularly when sustained and relapsing, as they are difficult to treat and are associated with high mortality. The main mechanism involved in the maintenance of ventricular tachycardias is the mechanism of reentry, due to myocardial scars secondary to various structural heart diseases. The electrical storm may be serious when it occurs in patients with automatic defibrillators, causing multiple corresponding shocks outside the hospital setting. In these cases, admission to hospital is necessary, where specific and stepwise treatment measures are performed, ranging from clinical management to specific interventions, such as programming of electronic devices, and electrophysiological or surgical interventions

ABSTRACT

Abstract: Infantile hemangioma can be linked to other organ malformations. In 1996, PHACE syndrome was first defined as the association of large and segmental infantile hemangioma, usually on the face, head, or cervical region, with malformations of the posterior fossa of the brain, arterial anomalies of the central nervous system, coarctation of the aorta, cardiac defects, and ocular abnormalities. Over 300 cases of PHACE syndrome have been reported, and it is cconsidered one of the most common neurocutaneous vascular disorders in childhood. Knowledge of the features and locations of lesions that imply a greater risk of systemic involvement is crucial for the diagnosis and proper management of PHACE syndrome patients. This review highlights the diagnostic criteria for PHACE syndrome, the imaging workup for extracutaneous involvement, the treatment of infantile hemangioma, and the importance of a multidisciplinary approach in the management of these patients.

ABSTRACT

Los hemangiomas son tumores vasculares benignos con características biológicas muy específicas en la infancia; estos se pueden localizar en órganos, y reciben el nombre de internos, o en cabeza, cuello, tronco y extremidades, que son los denominados externos, los cuales crecen a una velocidad variable. Con este trabajo se buscó exponer algunas particulares clinicoepidemiológicas de los hemangiomas externos, su clasificación, diagnóstico y evolución. Asimismo, se refieren aspectos relacionados con la efectividad del propranolol como propuesta terapéutica de primera elección en niños y se presentan los resultados de algunos autores al respecto, que en su mayoría convergen en cuanto a la aplicación de este medicamento como de primera línea.


Hemangiomas are benign vascular tumors with very specific biological characteristics during childhood; these tumors can be located in organs, and receive the name of internal, or in head, neck, trunk and extremities that are denominated external, which grow to a variable speed. Some clinical epidemiological particularities of external hemangiomas were exposed with this work, such as their classification, diagnosis and clinical course. Also, there is a reference to some aspects related to the effectiveness of propranolol as therapeutic proposal of first election in children and the results of some authors in this respect are presented, most of which coincide as for its use as first line medication.

ABSTRACT

OBJECTIVES: Vocal tremors, which cause social difficulties for patients, may be classified as resting or action tremors. Of the vocal action tremors, essential and dystonic tremors are the most common. Botulinum toxin and oral medications have been used to treat vocal tremors, but no comparative clinical trials have been performed. The aim of this study was to compare the effects of botulinum toxin injection and the oral administration of propranolol in the treatment of essential and dystonic vocal tremors. METHODS: This clinical trial recruited 15 patients, divided into essential and dystonic vocal tremor groups. Patients in both groups received successive treatment with botulinum toxin and propranolol. The treatments were administered at different times; the order of treatment was randomly selected. Patients were assessed with flexible nasofibrolaryngoscopy and with perceptual and acoustic voice evaluations. A statistical significance level of 0.05 (5%) was used. RESULTS: Botulinum toxin produced statistically significant improvements in perceptual measures of vocal instability in patients with dystonic vocal tremors compared with baseline values and treatment with propranolol. The acoustic measure of variability in the fundamental frequency was significantly lower in patients with dystonic vocal tremors after treatment with botulinum toxin. CONCLUSION: Essential and dystonic vocal tremors responded differently to treatment. Dystonic vocal tremors responded significantly to treatment with botulinum toxin but not oral propranolol. Essential vocal tremors did not respond significantly to either treatment, perhaps due to the small number of patients, which is a limitation of this research.

ABSTRACT

Los hemangiomas de la infancia (HI) son tumo-res vasculares que presentan un patrón evolutivo característico. Existe un subgrupo de HI que pre-senta un tipo de crecimiento distinto denominados hemangiomas de la infancia con crecimiento míni-mo o detenido (HI-CMD). En estos, el componen-te proliferativo no supera el 25% de la superficie total; además, afecta a niños de al menos dos meses de edad en la consulta inicial o a niños menores de dicha edad en los que se realiza un seguimiento mayor a 2 meses. Los HI- CMD con lipoatrofia son una variante poco frecuente de HI de la cual exis-ten escasos reportes en la literatura. El objetivo de nuestro trabajo es presentar un caso de HI-CMD con lipoatrofia en una lactante. Los HI-CMD presentan un desafío diagnóstico ya que deben ser reconocidos precozmente y diferencia-dos de otras lesiones vasculares.


Infantile hemangiomas (IH) are vascular tumors that present a characteristic evolutive pattern. There is a subgroup of hemangiomas that pre-sents a different type of growth called infantile hemangiomas with minimal or arrested growth (IH-MAG). In these, the proliferative component does not exceed 25% of the total surface; it also affects children of at least two months of age in the initial consultation or children under that age in which a follow-up of more than 2 months is carried out. IH-MAG with lipoatrophy is a rare variant of IH of which there are few reports in the literature.The aim of our report is to present a case of IH-MAG with lipoatrophy in an infant. IH-MAGs present a diagnostic challenge since they must be recognized early, and differentiated from other vascular lesions.

ABSTRACT

Abstract Introduction: Vestibular migraine (VM) is now accepted as a common cause of episodic vertigo. Treatment of VM involves two situations: the vestibular symptom attacks and the period between attacks. For the latter, some prophylaxis methods can be used. The current recommendation is to use the same prophylactic drugs used for migraines, including β-blockers, antidepressants and anticonvulsants. The recent diagnostic definition of vestibular migraine makes the number of studies on its treatment scarce. Objective: To evaluate the efficacy of prophylactic treatment used in patients from a VM outpatient clinic. Methods: Review of medical records from patients with VM according to the criteria of the Bárány Society/International Headache Society of 2012 criteria. The drugs used in the treatment and treatment response obtained through the visual analog scale (VAS) for dizziness and headache were assessed. The pre and post-treatment VAS scores were compared (the improvement was evaluated together and individually, per drug used). Associations with clinical subgroups of patients were also assessed. Results: Of the 88 assessed records, 47 were eligible. We included patients that met the diagnostic criteria for VM and excluded those whose medical records were illegible and those of patients with other disorders causing dizziness and/or headache that did not meet the 2012 criteria for VM. 80.9% of the patients showed improvement with prophylaxis (p < 0.001). Amitriptyline, Flunarizine, Propranolol and Topiramate improved vestibular symptoms (p < 0.001) and headache (p < 0.015). The four drugs were effective in a statistically significant manner. There was a positive statistical association between the time of vestibular symptoms and clinical improvement. There was no additional benefit in hypertensive patients who used antihypertensive drugs as prophylaxis or depressed patients who used antidepressants in relation to other prophylactic drugs. Drug association did not show statistically significant results in relation to the use of a single drug. Conclusions: Prophylactic medications used to treat VM improve the symptoms of this disease, but there is no statistically significant difference between the responses of prophylactic drugs. The time of vestibular symptom seems to increase the benefit with prophylactic treatment.


Resumo Introdução: A migrânea vestibular (MV) é aceita atualmente como uma causa comum de vertigem episódica. O tratamento da MV envolve duas situações: as crises de sintomas vestibulares e o período intercrise. Para esse último, pode-se usar algum método de profilaxia. A recomendação atual é que se usem os mesmos medicamentos profiláticos usados para a enxaqueca, o que inclui os β-bloqueadores, antidepressivos e anticonvulsivantes. A recente definição diagnóstica da migrânea vestibular torna escasso o número de estudos sobre seu tratamento. Objetivo: Avaliar a eficácia do tratamento profilático usado em pacientes em um ambulatório de MV. Método: Revisão de prontuários de pacientes com MV pelos critérios da Bárány Society/International Headeache Society de 2012. Foram pesquisados os medicamentos usados e resposta ao tratamento obtida através da escala visual analógica (EVA) para tontura e cefaleia. Foram comparados os escores da EVA pré e pós-tratamento (a melhoria foi avaliada em conjunto e individualmente por droga usada). Também foram pesquisadas relações com subgrupos clínicos dos pacientes. Resultados: De 88 prontuários estudados, 47 foram elegíveis. Incluíram-se os pacientes que preenchiam os critérios diagnósticos para MV, foram excluídos os prontuários ilegíveis e aqueles de pacientes com outro distúrbio causador de tontura e/ou cefaleia que não preenchiam critérios de 2012 para MV. Apresentaram melhoria com a profilaxia 80,9% dos pacientes (p < 0,001). Amitriptilina, flunarizina, propranolol e topiramato apresentaram melhoria para sintomas vestibulares (p < 0,001) e para cefaleia (p < 0,015). Os quatro medicamentos foram eficazes de forma estatisticamente significante. Houve relação estatística positiva entre tempo de sintoma vestibular e melhoria clínica. Não houve benefício adicional para hipertensos que usaram anti-hipertensivos como profilaxia ou para os deprimidos que usaram antidepressivos em relação ao uso dos outros profiláticos. A associação de medicamentos não mostrou resultados estatisticamente significantes do uso de um medicamento isolado. Conclusões: Os medicamentos profiláticos usados para MV melhoram os sintomas dessa doença, porém não há diferença estatisticamente significante entre as respostas dos medicamentos profiláticos. O tempo de sintoma vestibular parece aumentar a melhoria obtida com o tratamento profilático.

ABSTRACT

Hipertireoidismo é o excesso de função da glândula tireoide. É a principal causa de tireotoxicose, que, por sua vez, é a manifestação clínica do excesso de hormônios tireoidianos. O hipertireoidismo é mais comum em mulheres do que em homens (razão de 5:1), tendo como principais causas a Doença de Graves (60 % a 80% dos casos), etiologia típica em mulheres jovens com idade entre 20 a 40 anos, e o bócio multinodular tóxico (10 % a 30% dos casos), mais frequente em idosos. O adenoma tóxico e as tireoidites são menos comuns (1%). Hipertireoidismo e tireotoxicose também podem ser induzidos por medicamentos como amiodarona, interferon, levotiroxina e lítio. A doença deve ser investigada em pacientes com manifestações clínicas, não havendo recomendação para rastreamento populacional. Informações sobre tireotoxicose induzida por levotiroxina (TSH reduzido em paciente que faz uso de levotiroxina) podem ser obtidas no material TeleCondutas Hipotireoidismo. Esta guia apresenta informação que orienta a conduta para casos de hipertiroidismo no contexto da Atenção Primária à Saúde, incluindo: sinais e sintomas, diagnóstico do hipertireoidismo, tratamento do hipertireoidismo, tratamento do hipertireoidismo subclínico, hipertireoidismo na gestação, encaminhamento para serviço especializado.
