The incidence and clinical characteristics of impulse control disorders in patients with prolactinoma receiving dopamine agonist / 中华内分泌代谢杂志

Objective:To understand the incidence and clinical characteristics of dopamine agonist(DA) therapy-related impulse control disorders(ICDs) in prolactinoma patients.Methods:Outpatients diagnosed with prolactinoma from the Department of Endocrinology in Huashan Hospital from December 2019 to June 2020 were consecutively included and clinical data were collected. Impulse control disorders were screened with Questionnaire for Impulsive-Compulsive Disorders in Parkinson′s Disease(QUIP). Barratt Impulsiveness Scale 11(BIS-11) was used to evaluate personality construct of impulsiveness from three sub-factors . Health related quality of life was evaluated by the MOS 36-Item Short Form Health Survey(SF-36).Results:Among the 111 cases included, 40 were male and 53 were female, with an average age of(34.74±9.05) years and an average disease duration of(66.69±50.70) months. The initial prolactin level was 147.25(89.97, 470) ng/mL and the percentage of macroadenoma was 46.8%. Ninety cases received DA while 21 cases didn′t. According to the QUIP, any ICD was screened positive in 22 cases(24.7%) in the DA group and 3 cases(14.3%) in the untreated group. The attention impulsiveness scores of BIS-11 in the DA group were higher than the untreated group(23.32±3.67 vs 21.71±2.55, P=0.022). Among the ICDs positive cases in the DA group, the most common disorders were pathological gambling(40.6%) and hypersexuality(40.6%). Compared with the negative group, the non-planning impulsiveness scores of BIS-11 in the positive group were higher, while the scores of social function(69.32±24.62 vs 83.08±17.11, P=0.021), role emotional(50.00±45.72 vs 71.10±40.68, P=0.043) and mental health(55.27±22.75 vs 64.59±17.53, P=0.048) in SF-36 scale were lower in the positive group. Besides, the percentage of male(68.2% vs 38.2%, P=0.014) and initial prolactin level[470.00(130.00, 3 770.00) vs 140.29(79.50, 465.59) ng/mL, P=0.028] in the positive group were higher. Male was an independent risk factor of the presence of ICDs( OR=3.46, 95% CI 1.24-9.61, P=0.017). No significant difference was found in the type of drugs, duration, maximal or cumulative dose of treatment with DA between the two groups. Conclusion:Impulse control disorders may occur in prolactinoma patients receiving DA treatment and affect the quality of life. Endocrinologists should screen impulse control disorders in this patient set.

The Impact of Impulsivity on Quality of Life in Early Drug-Naïve Parkinson's Disease Patients

OBJECTIVE: Impulse control disorders (ICDs) in Parkinson's disease (PD) are mostly related to dopamine replacement therapy (DRT); however, drug-naïve PD patients have also frequently experienced impulsivity. This phenomenon makes clinicians hesitate treating patients with DRT. In this study, we assessed the effect of impulsivity on quality of life (QOL) in drug-naïve PD patients. METHODS: Two hundred three newly diagnosed, nonmedicated PD patients were enrolled, and they received structured clinical interviews, physical examinations and validated questionnaires to evaluate motor and nonmotor symptoms and QOL. Impulsivity was evaluated using the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS). RESULTS: Thirty-eight patients (18.7%) had impulsivity with QUIP-RS scores ≥ 1 and 4 patients (2.0%) were diagnosed with combined ICDs. Motor and nonmotor symptoms were significantly correlated with the Parkinson's Disease Questionnaire-39 summary index. Female sex and QUIP-RS scores were also correlated with QOL in drug-naïve PD patients. CONCLUSION: The results of the present study showed that impulsivity negatively influences QOL in early drug-naïve PD patients. In addition, more severe motor and nonmotor symptoms were also associated with lower QOL. Such findings complicate treatment but provide valuable information for managing early PD.

Psychiatric Manifestation in Patients with Parkinson's Disease

Parkinson's disease (PD) is the second most common neurodegenerative disorder. Although its major manifestation is motor symptoms, resulting from the loss of dopaminergic neurons in the substantia nigra, psychiatric symptoms, such as depression, anxiety, hallucination, delusion, apathy and anhedonia, impulsive and compulsive behaviors, and cognitive dysfunction, may also manifest in most patients with PD. Given that the quality of life — and the need for institutionalization — is so highly dependent on the psychiatric well-being of patients with PD, psychiatric symptoms are of high clinical significance. We reviewed the prevalence, risk factors, pathophysiology, and treatment of psychiatric symptoms to get a better understanding of PD for improved management.

Trastorno explosivo intermitente: un diagnóstico controversial / Intermittent Explosive Disorder: A Controversial Diagnosis

Introducción: El trastorno explosivo intermitente (TEI) es un trastorno externalizante que se caracteriza por episodios recurrentes de agresividad. Aunque es un trastorno descrito desde hace varias décadas, y que ocasiona consecuencias personales y sociales, la producción bibliográfica sobre este tema es sorprendentemente escasa. Objetivo: Realizar una conceptualización sobre el TEI a partir de la revisión y el análisis bibliométrico de los artículos científicos disponibles. Material y métodos: Se realizó una búsqueda en las bases de datos con los términos en inglés intermittent explosive disorder, impulse control disorders [MeSH] en combinación con otros términos. Se realizó un análisis bibliométrico utilizando los datos obtenidos en el buscador GoPubMed®. Discusión: La prevalencia del TEI oscila entre el 1,4 y el 7%, con mayor frecuencia durante la adolescencia media, y con más repercusiones notorias en varones que en mujeres. El núcleo psicopatológico del TEI es la conducta agresiva impulsiva que se presenta en forma de «ataques¼ que ocurren en respuesta a un estímulo precipitante menor. Las publicaciones científicas sobre el TEI son pocas, relativamente recientes, y la mayoría de Estados Unidos (56,56%), en cabeza un solo autor. Este hecho resalta la necesidad de repetir los hallazgos descritos sobre el TEI para demostrar validez y confiabilidad de sus criterios diagnósticos. Es posible que las dudas sobre la existencia del diagnóstico estén conduciendo a que se publique tan escasamente sobre el TEI. Conclusiones: Los estudios disponibles sobre TEI permiten caracterizar un grupo de sujetos con episodios de agresividad impulsiva, pero esta descripción requiere que se repita en latitudes diferentes.

Introduction: Intermittent explosive disorder (IED) is aan externalizing externalising disorder characterized characterised by recurrent aggression episodes. Even though this disorder was described several decades ago, and it carries personal and social consequences, there is little in the medical scientific literature on this. bibliographic production about it is scanty. Objective: To perform a conceptualization conceptualisation of this disorder, through the review and bibliometric analysis of the available scientific articles. Material and methods: A search was performed in databases with the english English terms intermittent explosive disorder, impulse disorders control [MeSH], in combination with other terms. A bibliometric analysis in the GoPubMed® search engineer was also performed using all data obtained in the search. was also perfomed. Discussion: IED prevalence ranges from 1.4% to 7%, it presents more frequently during middle adolescence, and with more noticeable repercussions in men males than in womenfemales. The psychopathological core of IED is the impulsive aggressive behaviour that presents in the form of «attacks¼ that occurs in response to a lower precipitating stimulus. Scientific publications about IED are few and relatively recent, and the vast majority is provided bycomes from the United States (56.56%), and headed by a single author. This fact highlights the need to replicate the findings described about the IED in order to demonstrate the validity and reliability of its diagnostic criteria. It is possible that doubts about the existence of a diagnosis lead have led to such a scant literature about the IED. Conclusions: Available studies about IED allow have allowed characterizing a group of subjects with episodes of impulsive aggression to be characterised, but this description requires replication in different latitudes needs to be repeated in different areas.

Rehabilitation for Parkinson Disease / The Japanese Journal of Rehabilitation Medicine

Patients with Parkinson disease present with a variety of symptoms as well as the so-called 4 classic symptoms : tremor, muscle rigidity, akinesia, and postural instability. To treat this disease, the best combination of various antiparkinsonism drugs, deep brain stimulation, and rehabilitation should be determined and administered. Muscular training in rehabilitation for patients should place great importance on some especially vulnerable muscles including the truncal muscles, extensor muscles for hip and knee joints, and dorsiflexor muscles for ankle joints. Shifting the center of gravity and using rhythmic movements are important factors in getting the patient standing and walking. Training using visual and auditory cues and music is effective in Parkinson disease. Speech therapy using weighted noise is also available. In rehabilitation we have to pay attention to cognitive function and psychiatric symptoms in patients including depression, anhedonia, hallucination, delusion, dopamine dysregulation syndrome, and impulse control disorder. What priority should be set for rehabilitation differs according to the stages of disease. Utmost efforts must be made for patients in the advanced stage of Parkinson disease to prevent them from being bedridden, tube-fed, and demented. Medical staff must be creative in coming up with new ideas to assist such patients in sitting comfortably on chairs for long periods and in eating by mouth safely.

Tricotilomania em um caso de demência / Trichotillomania in a dementia case

We report an 87-year-old male case of hair pulling associated with a white-matter vascular dementia (Binswangers disease). Trichotillomania in our case did not resolve using mirtazapine or anticholinesterasic medication. Trichotillomania seems to be related to a form of perseveration associated with dementia. The findings in this case suggest the abnormality involving white matter in the pathogenesis of trichotillomania, may constitute a defect in connectivity in the right frontal-subcortical circuit.

Relatamos o caso de um homem de 87 anos com tricotilomania associada com uma demência vascular da substância branca (doença de Binswanger). Tricotilomania no nosso caso não se resolveu com mirtazapina nem com medicação anticolinesterásica. Tricotilomania parece se relacionar a uma forma de perseveração associada à demência. Podemos sugerir com este caso que a alteração que envolve a substância branca na patogênese da tricotilomania pode ser uma falha na conectividade no circuito fronto-subcortical direito.

Pathologic Gambling in Parkinson Disease

Pathologic gambling (PG) is an impulse control disorder (ICD) or dopamine dysregulation syndrome (DDS) in patients with Parkinson disease (PD). ICD/DDS is presumed to be related to dopaminergic treatment in PD. Although increasing number of patients with ICD/DDS is being reported, ICD/DDS such as PG has not been reported in Korean PD patients. We describe a PD patient who developed PG secondary to dose adjustment of levodopa and pramipexole. His symptoms was controlled by reducing the dopaminergic drugs and adding a small amount of atypical antipsychotics.

Transtornos parafílicos em pacientes com transtorno obsessivo-compulsivo: série de casos / Paraphilic disorders among patients with obsessive-compulsive disorder: case series

Com o intuito de elucidar a relação entre transtornos do controle de impulsos (TCI) e transtorno obsessivo-compulsivo (TOC), faz-se mister estudar subgrupos mais clinicamente homogêneos de transtornos impulsivos. Por meio do relato de quatro casos de pacientes com TOC e diferentes tipos de transtornos parafílicos (fetichismo transvético, sadismo, ginandromorfofilia e exibicionismo), são discutidos os conceitos de compulsividade, impulsividade e a relação temporal entre ambos. O estudo dos casos aqui descritos mostra que (1) pacientes com TOC e transtornos parafílicos tendem a desenvolver o TOC primeiro, (2) diante de desejos, fantasias ou atos sexuais parafílicos, pacientes com TOC podem lançar mão de comportamentos tipicamente compulsivos, (3) pacientes com TOC e obsessões sexuais egodistônicas podem desenvolver desejos, fantasias ou atos sexuais parafílicos de conteúdo semelhante ao das obsessões, (4) em um mesmo paciente, TOC e parafilias podem apresentar cursos independentes, e (5) pacientes com TOC e parafilias podem não apresentar obsessões sexuais. O sofrimento de pacientes com TOC e parafilias justifica a investigação continuada de tais condições no intuito de elucidar os mecanismos que subjazem esta associação e de criar estratégias que aumentem a adesão ao tratamento.

In order to elucidate the relationship between impulse control disorders and obsessive-compulsive disorder (OCD), it is essential to study more clinically homogenous subgroups of patients with impulsive disorders. Using four cases of patients with OCD and comorbid paraphilias (transvestic fetishism, sadism, gynandromorphophilia, and exhibitionism) as reference-points, we discuss the concepts of compulsivity, impulsivity, and the temporal relationship between them. The case studies here described suggest that (1) patients with OCD and comorbid paraphilias tend to develop OCD first, (2) once developing paraphilic fantasies, desires, or behaviors, patients with OCD can exhibit typical compulsive behaviors in an attempt to keep these phenomena under control, (3) patients with OCD and ego-dystonic sexual obsessions can develop paraphilic fantasies, desires, or behaviors with similar content to the first phenomenon, (4) OCD and paraphilias can follow independent courses in the same patient, and (5) patients with OCD and paraphilias may not present obsessions with sexual content. The distress presented by patients with OCD and paraphilias give good reason for the continuous investigation of this association, aiming at clarifying the neurobiological mechanisms underlying this association.
