RESUMO

INTRODUCTION: Tourette's Syndrome (TS) is a neurodevelopmental disorder characterized by motor and / or vocal tics for more than 12 months. TS affects about 0.8% of pediatric patients and is associated with great functional impairment and psychological distress. The present study aims to list and compare the effectiveness of therapies used in children and young people with TS. METHODS: PubMed / MEDLINE, Cochrane Library, ScienceDirect, SciELO and Lilacs were used from September 2020 to April 2021 to search for randomized clinical trials with pharmacological, behavioral, physical or alternative interventions for tics in children and young people with ST. RESULTS: 13 clinical trials were included, of which six pharmacological, six behavioral and one of other conformation. The global score on the Yale Global Tic Severity Scale showed evidence in favor of Habit Reversal Training (HRT) and Comprehensive Behavioral Intervention for Tics (CBIT). Evidence from two studies suggests that antipsychotic medications improve tic scores. Evidence from other interventions has shown no conclusive benefit. CONCLUSIONS: The present study identified benefits with the use of antipsychotics. The study also found that HRT and CBIT showed improvement in reducing the severity of tics, in addition to not having any adverse effects. These therapies showed significant clinical improvement, but there is no comparison between the use of these isolated approaches in relation to their use associated with medications. In view of the different forms of therapy, further studies are needed to identify the effectiveness and the profile of adverse effects of these interventions.

INTRODUÇÃO: A Síndrome de Tourette (ST) é um distúrbio do neurodesenvolvimento caracterizado por tiques motores e/ou vocais por mais de 12 meses. A ST afeta cerca de 0,8% dos pacientes pediátricos e associa-se a grande comprometimento funcional e sofrimento psíquico. O presente estudo tem como objetivo listar e comparar a eficácia das terapias utilizadas em crianças e jovens com ST. MÉTODOS: PubMed/MEDLINE, Cochrane Library, ScienceDirect, SciELO e Lilacs foram usados desde setembro de 2020 até abril de 2021 para a busca de ensaios clínicos randomizados com intervenções farmacológicas, comportamentais, físicas ou alternativas para tiques em crianças e jovens com ST. RESULTADOS: 13 ensaios clínicos foram incluídos, dos quais seis farmacológicos, seis comportamentais e um de outra conformação. A pontuação global na Yale Global Tic Severity Scale, apresentou evidências a favor do Treinamento de Reversão de Hábito (TRH) e Intervenção Comportamental Abrangente para Tiques (ICAT). As evidências de dois estudos sugerem que medicamentos antipsicóticos melhoram os escores de tiques. Evidências de outras intervenções não mostraram nenhum benefício conclusivo. CONCLUSÕES: O presente estudo identificou benefícios com o uso do antipsicóticos. O estudo também identificou que a TRH e a ICAT apresentaram melhora na redução da gravidade dos tiques, além de não apresentarem efeitos adversos. Essas terapias mostraram importante melhora clínica, mas não há comparação entre o uso dessas abordagens isoladas em relação ao seu uso associado com medicamentos. Diante das diferentes formas de terapia, mais estudos são necessários para identificar a eficácia e o perfil de efeitos adversos dessas intervenções.

RESUMO

BACKGROUND: Tics are the hallmark of Tourette syndrome (TS). However, TS patients may have a particular vulnerability to develop other movement disorders (MDs), such as dystonia, chorea, stereotypy, and other hyperkinetic disorders that may be wrongly attributed to tics. MATERIALS AND METHODS: We studied a cohort of 201 patients with motor and phonic tics associated with TS to determine if they have additional, co-existent, MDs. RESULTS: There were 67 (33.3%) patients with comorbid non-tic MDs. Phenomenology-wise, piano-playing movements resembling chorea or myoclonus, were the most common non-tic movement, observed in 11% of cases, followed by stereotypies (8.0%), tremor, dystonia and parkinsonism, 5.0% each. Drug-induced was the most common etiology (6.0%), followed by functional movement disorders (5.0%) and tardive phenomena (5.0%). No clear etiology was identified in most patients. Piano-playing movements, were associated with a younger age at onset (P = 0.004) and younger age at presentation (P < 0.001). Patients with drug-induced movements and tardive phenomena had a lower frequency of craniofacial tics. FMDs, and idiopathic MDS showed no specific associations with TS. Tic severity was not a predictor of any co-existent MD. CONCLUSION: About a third of patients with TS present with comorbid MDs which should be differentiated and distinguished from tics as their etiopathogenesis and treatment may be different.

RESUMO

INTRODUCTION: Tourette Syndrome (TS) is a common disorder with chronic motor and phonic tics, associated with neuropsychiatric comorbidities. OBJECTIVE: To characterize clinical-demographic variables, comor bidities, and management in a pediatric cohort with TS and compare them according to sex. PATIENTS AND METHOD: A retrospective cohort of patients < 18 years old with TS followed up between 2000 and 2018 was evaluated. Clinical records were reviewed obtaining variables of age, sex, reason for consul tation, age of onset, type and complexity of tics, follow-up time, family history, obsessive behaviors, neuropsychiatric and psychopathological comorbidity, neurological disorders, and pediatric mor bidity. Studies and treatments performed, and management used were also recorded. RESULTS: 126 patients were included, aged between 4-18 years, 103 males (sex F:M ratio = 4.5:1), with a follow-up of 4.8 ± 1.9 years. The mean age of tic onset and TS diagnosis was 6.5 ± 2.2 and 9.4 ± 2.7 years, res pectively, and a diagnostic latency of 2.8 ± 2.2 years. The first consultation in the total of girls was due to tics, in contrast to the boys of whom 14.6% (n = 15) consulted due to comorbidities. There was 38.9% of tics and 8,7% of TS. Neuropsychiatric comorbidities were frequent, recorded in 69.8%, with Attention Deficit Disorder (43.6%) and Obsessive-Compulsive Disorder (20.6%) standing out.110 cases (87.3%), received pharmacological therapy and 54.4% required three or more drugs at some point in their evolution. Only in 16 cases (12.7%), no pharmacological therapy was required, only psychoeducation in 7 (5.6%) cases, and behavioral therapy in 9 cases (7.1%). CONCLUSIONS: The cli nical characteristics of our children with TS are similar to international descriptions, highlighting that in the group of boys, the first consultation could be due to comorbidity, recognizing later the presence of tics. Although psychoeducation and behavioral therapies are recommended as first-line management, most of the patients in this group required pharmacological therapy.

RESUMO

OBJECTIVE: To assess the efficacy of electroconvulsive therapy (ECT) in DSM-5 obsessive-compulsive-related disorders (OCRDs) and conditions subsumed under an "extended" OCD spectrum, including tic disorders and self-injurious behaviors. DATA SOURCES: A systematic search of the MEDLINE, Web of Science, Scopus, and LILACS databases and other sources was performed between June 6 and July 2, 2017. Search terms included (Autis*) AND (ECT OR electroconvulsive), (Self-injur*) AND (ECT OR electroconvulsive), (Tic* OR Tourette) AND (ECT OR electroconvulsive), (Body Dysmorphic Disorder OR Dysmorphophobi*) AND (ECT OR electroconvulsive), (Hoard*) AND (ECT OR electroconvulsive), (Trichotillomani*) AND (ECT OR electroconvulsive), (Skin Picking OR Excoriation) AND (ECT OR electroconvulsive), (Grooming) AND (ECT OR electroconvulsive), (Kleptomani*) AND (ECT OR electroconvulsive), and (Pyromani*) AND (ECT OR electroconvulsive). No search restrictions (ie, date, language, or document type) were used. STUDY SELECTION: Fifty-two records that described the individual responses of OCRDs to ECT (involving 69 patients) were selected. DATA EXTRACTION: Clinical data and responses of individual cases were recorded. Data from responders were compared to nonresponders. RESULTS: All records were case reports or case series; there were no randomized controlled trials. Of the 69 OCRD participants who had undergone ECT, a positive response was reported in 73.4% of the cases (including 44.0% of the BDD, 74.1% of the tic disorder, and 85.7% of the self-injurious behavior patients). At follow-up, the majority of responders who had abstained from further ECT had experienced relapse. However, a positive response was obtained in all participants who received a new course of ECT. Patients who responded positively to ECT were likely to report previous unsuccessful treatment with antipsychotics (P < .001) and antidepressants (P = .007). CONCLUSIONS: The finding that more than 70% of the reviewed cases showed some response to ECT should not be considered unequivocal evidence of its efficacy in OCRDs. The available evidence suggests that a randomized controlled trial of ECT in OCRDs may be warranted, particularly in severe tic disorders and self-injurious behaviors.

RESUMO

Tourette's syndrome (TS) is defined as a disorder characterized by multiple motor tics and at least one vocal tic that have lasted for not less than one year. It is a relatively complex neurobehavioral disorder, in which patients may present with coexistent attention deficit hyperactivity disorder, obsessive-compulsive disorder or other behavioral comorbidities. The musical genius Wolfgang Amadeus Mozart (1756-1791) and the rock star Kurt Cobain (1967-1994) may both have suffered from TS, and some contemporary musicians have had their clinical condition confirmed as TS. Our hypothetical diagnosis of TS in Mozart and Cobain is based on the presence of tics and psychiatric comorbidities. In contemporary musicians, such as Michael Wolff, Nick Van Bloss and James Durbin, TS has often only been diagnosed after a considerable delay. This delay in diagnosis and the controversies surrounding the clinical case of Mozart show how difficult a confirmatory diagnosis of this complex disease is.

A síndrome de Tourette (TS) é definida como uma desordem caracterizada por múltiplos tiques motores e pelo menos um tique vocal com duração de ao menos um ano. TS é um distúrbio neuro-comportamental relativamente complexo, em que os pacientes teriam coexistente transtorno de déficit de atenção e hiperatividade, transtorno obsessivo-compulsivo, distúrbio de comportamento ou outras co-morbidades. Talvez sejam casos de TS o do gênio musical Wolfgang Amadeus Mozart (1756-1791) e da estrela do rock, Kurt Cobain (1967-1994). Alguns músicos contemporâneos tiveram a sua condição clínica confirmada como TS. Em conclusão, os diagnósticos hipotéticos de TS nos casos de Mozart e Cobain podem ter embasamento na possibilidade de tiques e comorbidades psiquiátricas. Observou-se um atraso de diagnóstico de TS em músicos contemporâneos (Michael Wolff, Nick Van Bloss, James Durbin). Essa situação e as controvérsias sobre a clínica no caso de Mozart mostram a dificuldade para confirmação do diagnóstico dessa complexa doença.

RESUMO

An 11-year-old girl was transferred to the Universidad de Chile Clinical Hospital after 2.5 months of persistent and unresponsive treatment for coughlike spasms. On arrival, the frequency of symptoms was 1 cough every 4 s, which disappeared during sleep. A multidisciplinary examination excluded allergic, viral, respiratory, epileptic, and other more usual causes of similar conditions. Two diagnoses (psychogenic cough and transient vocal tic disorder) and a mixed intervention were proposed leading to resolution in 12 days of treatment. No recurrence of symptoms was observed during several evaluations within 12 months of medical follow-up. An association between the 2 diagnoses is proposed and discussed.

RESUMO

Tourette syndrome (TS) and tic disorders represent events of familiar magnitude characterized by involuntary movements and/or vocalization. To determine the prevalence of TS/tic disorders we studied a sample of 762 subjects (388 M, 374 F), between 1992 and 1997, age 6 to 43 years old, taken out of a population of 10,155 subjects (4,918 M, 5,237 F; age: 3-56 years old). A structured 4-item questionnaire, direct interview (multistaged), >1 yr follow-up, were used. 9,565 subjects (4,614 M, 4,951 F) sent back the questionnaires, 3,354 of these (1,671 M, 1,683 F) with positive answers to tics. 42 subjects (31 M, 11 F, age: 7-21 years old, mean: 11 years old) met the DSM-III-R criteria. The total minimal prevalence of TS is 0.43%, with a 3:1 ratio male/female. The minimal prevalence of chronic tic disorder is 2.27%. The total minimal prevalence for tic disorders at all is 2.91%. No special education students participation.

RESUMO

This article reflects discussion by the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders. After reviewing the historical classification of tic disorders, this article discusses their placement in ICD-11. Existing problems with diagnostic labels and criteria, appropriate placement of the tic disorders category within the ICD-11 system, and pragmatic factors affecting classification are reviewed. The article ends with recommendations to (a) maintain consistency with the DSM-5 diagnostic labels for tic disorders, (b) add a minimum duration guideline for a provisional tic disorder diagnosis, (c) remove the multiple motor tic guideline for the diagnosis of Tourette disorder, and (d) co-parent the tic disorder diagnoses in the disorders of the nervous system and the mental and behavioral disorders categories, with secondary co-parenting in the obsessive-compulsive and related disorders and neurodevelopmental disorders sections.
