Ekbom Syndrome associated with Lewy Body Dementia: A case report / Síndrome de ekbom associada à demência com corpos de lewy: um relato de caso

ABSTRACT Ekbom Syndrome, also known as parasitosis delusion or psychogenic parasitosis, is a rare condition in which patients present with a fixed belief of being infested by parasites, vermin or small insects, along with tactile hallucinations (such as pruritus or sensations of the parasites crawling over or under the skin). The syndrome may occur idiopathically or be associated with other medical conditions and drug use. This case report describes the occurrence of Ekbom syndrome in a patient diagnosed with Lewy Body Dementia (LBD), a neurodegenerative disease that commonly presents with sensory perception and thought disorders and other neuropsychiatric symptoms. Although visual hallucination is considered a core diagnostic criterion, other modalities of psychiatric symptoms can also occur posing a further challenge for correct diagnosis. Proper recognition allows early diagnosis and adequate treatment, preventing hazardous antipsychotic use in these patients.

RESUMO A síndrome de Ekbom, também conhecida como delírio parasitário ou parasitose psicogênica, é uma condição rara na qual os pacientes apresentam crença fixa de estarem infestados por parasitas, vermes ou insetos, acompanhada de alucinações táteis (como prurido ou sensação dos parasitas andando sobre ou sob a pele). A síndrome pode ocorrer de forma idiopática ou associada a outras condições médicas ou uso de drogas. Este relato de caso descreve a ocorrência da síndrome de Ekbom em um paciente diagnosticado com Demência com corpos de Lewy (DCL), uma doença degenerativa que comumente se apresenta com desordens de sensopercepção e pensamento, e outros sintomas neuropsiquiátricos. A alucinação visual é considerada um dos critérios diagnósticos nucleares, entretanto outras modalidades de sintomas psiquiátricos podem ocorrer criando desafios adicionais ao diagnóstico correto. O reconhecimento apropriado permite o diagnóstico precoce e tratamento adequado, prevenindo o uso arriscado de antipsicóticos nesses pacientes.

Delirio de parasitosis o síndrome de ekbom / Dilusional parasitosis or Ekbom syndrome

El síndrome de Ekbom también llamado delirio de parasitosis es una condición psiquiátrica poco frecuente en el que los pacientes tienen una idea falsa y fija de estar infestados por parásitos o materiales inanimados. Se presenta el caso de un varón de 54 años con cuadro crónico compatible con este síndrome en el que resalta la buena respuesta a antipsicótico típico a un inicio, complicándose el mismo con discinecia tardía por síntomas extrapiramidales, por lo que se realiza el cambio de tratamiento con buena respuesta a la Risperidona.

Ekbom's syndrome also called Delusional Parasitosis is a rare mental disorder in which patients have a false and fixedidea of being infested by parasites or inanimate materials. A case of a 54-year-old man with a chronic condition compatible with this syndrome is reported. Initially, a good response to typical antipsychotic was highlighted, however it got complicated by a tardive dyskinesia due to extrapyramidal symptoms. Consequently, change of treatment with risperidone resulted in good response.

Restless Legs Syndrome, and symptoms of Restless Syndrome in patients with Graves disease: a cross-sectional survey

OBJECTIVES: Restless legs syndrome (RLS) is a frequent comorbid condition associated with distinct unrelated diseases. While the incidence of RLS has not been definitively confirmed, RLS-like symptoms have been reported in a section of Asian population who also had hyperthyroidism. The prevalence of RLS is generally low in Asian populations. Under these circumstances, we hypothesized that in a population where RLS is common, such as in Brazil, RLS could manifest as a comorbid ailment alongside Graves' disease, a common hyperthyroid condition. METHODS: In a cross-sectional survey, 108 patients who presented with Graves' disease were analyzed for restless legs or associated symptoms. RESULTS: Twelve patients (11.1%) displayed symptoms of RLS prior to the incidence of Graves' disease. These patients experienced worsening of the symptoms during their hyperthyroid state. Six patients (5.6%) developed RLS, consequent upon the incidence of Graves' disease as per the consensus of the panel of the experts. Fifteen patients (13.9%) also presented with RLS-like symptoms without any discernible circadian feature of the syndrome. CONCLUSION: Our findings confirm that Graves' disease might trigger restless legs-like symptoms, while the condition of hyperthyroidism could also be complicated by definite RLS.

Association between Restless Legs Syndrome Symptoms and Self-Reported Hypertension: a Nationwide Questionnaire Study in Korea

BACKGROUND: The association between restless legs syndrome (RLS) and hypertension remains controversial. We investigated the relationship between RLS and hypertension in a nationwide sample of the Korean adult population. METHODS: This was a cross-sectional questionnaire-based study including 2,740 adults aged 19 years or more. Subjects who met the four essential International RLS Study Group criteria and reported symptoms occurring at least once a week were defined as the RLS group. The presence of hypertension was defined as a self-reported history of physician-diagnosed hypertension. We conducted multiple logistic regression analysis to determine the independent association between RLS symptoms and self-reported hypertension after adjusting for potential confounding factors. RESULTS: Among the 2,740 subjects, 68 (2.5%; 95% confidence interval [CI], 1.9%–3.1%) were found to have RLS with a symptom frequency of at least once a week. The prevalence of self-reported hypertension was 30.9% (95% CI, 20.5%–42.0%) in the RLS group, which was significantly higher than that in controls (12.4%; 95% CI, 11.2%–13.6%; P < 0.001). Multiple logistic regression analysis showed that the adjusted odds ratio for self-reported hypertension in the RLS group was 2.10 (95% CI, 1.12–3.93) compared to controls. In addition to RLS symptoms, old age, being overweight, low education level, diabetes mellitus, and short sleep duration were significantly associated with self-reported hypertension. CONCLUSION: RLS symptoms occurring at least once a week is independently associated with a higher prevalence of self-reported hypertension in the adult Korean population. Further research will confirm the clinical implication of the present results and the causal relationship between RLS and hypertension.

Exclusion of mimics does not influence Willis-Ekbom disease diagnosis among recent medical graduates / Exclusão de fatores confundidores não influencia o diagnóstico da doença de Willis-Ekbom entre recém-formados em Medicina

ABSTRACT In view of the diagnostic challenge posed by restless legs syndrome/Willis-Ekbom disease (RLS/WED) to health professionals and the challenge of its recognition by patients, the diagnostic criteria have been revised and updated to facilitate identification of this disease. However, in a previous study, we found that self-diagnosis of RLS/WED depends on the very name used to describe the condition. Objective: To ascertain whether the presence of the fifth diagnostic criterion of the International Restless Legs Syndrome Study Group (IRLSSG), is necessary for RLS/WED diagnosis when the term "Willis-Ekbom disease" is used. Methods: We randomly distributed 705 forms to recent medical graduates, asking them to self-assess whether they had "Willis-Ekbom disease" (WED). In one questionnaire model, we excluded the fifth criterion suggested by the IRLSSG, while in the other, all five criteria were included. No forms contained the term RLS; only WED was used throughout. Results: Seven hundred and five recent medical graduates participated in the study. Among the 332 who received the form without the fifth criterion, 8 (2.41%) self-diagnosed as having WED (95%CI: 0.8%-4.1%). Of the 373 who received the form with all five of the 2014 IRLSSG criteria, 9 (2.41%) self-diagnosed as having WED (95%CI: 0.8%-4.0%) (p > 0.05). Conclusion: Our data show that presence of the fifth IRLSSG criterion did not influence self-diagnosis of WED among recent medical graduates, suggesting that the name WED reduces the odds of mimics (confounding conditions) being misinterpreted as symptoms of this disease. This finding indicates that for the diagnosis of RLS/WED only four criteria and a systematic use of the name WED are necessary.

RESUMO Frente ao desafio diagnóstico da síndrome das pernas inquietas/doença de Willis-Ekbom (SPI/DWE) pelos profissionais de saúde e também seu reconhecimento pelos pacientes, os critérios de diagnóstico vêm sendo revisados e atualizados para facilitar a identificação dessa doença, porém, em estudo anterior, observamos que o autodiagnóstico da SPI/DWE depende do próprio nome utilizado para descrevê-la. Objetivo: Verificar se a presença do quinto critério do International Restless Legs Syndrome Study Group (IRLSSG) é necessária para o diagnóstico da SPI/DWE quando utilizamos apenas a expressão/denominação DWE. Métodos: Distribuímos aleatoriamente 705 formulários solicitando a médicos recém-formados que avaliassem se eles tinham DWE. Em um tipo de questionário, excluímos o quinto critério diagnóstico sugerido pelo IRLSSG e no outro mantivemos os cinco critérios. Em nenhum formulário apresentamos o termo SPI, apenas DWE. Resultados: Setecentos e cinco médicos recém-formados participaram do estudo. Dentre os 332 médicos que receberam o formulário sem o quinto critério, 8 (2,41%) autodiagnosticaram-se com DWE (IC 95%: 0,8%-4,1%). Trezentos e setenta e três médicos receberam o formulário com os 5 critérios do IRLSSG (2014) e 9 (2,41%) autodiagnosticaram-se como tendo DWE (IC 95%: 0,8%-4,0%) (p > 0.05). Conclusão: Nossos dados mostraram que a presença do quinto critério do IRLSSG não influenciou a realização do autodiagnóstico da DWE entre médicos recém-formados, sugerindo que a denominação DWE reduz a chance de condições confundidoras serem tomadas como sintomas desta doença. Este achado está de acordo com dados anteriores, onde mostramos que o autodiagnóstico da SPI/DWE é dependente da denominação utilizada para descrever a doença.

Pregabalin for restless legs syndrome: A meta-analysis

@#Background & Objective: Various pharmacologic agents are currently being used to alleviate the symptoms of restless legs syndrome (RLS). The most commonly used drugs are dopaminergic agents, but due to augmentation, alternative medications like pregabalin are being studied. This study aims to determine the efficacy and safety of pregabalin compared to placebo in the treatment of sensory and/or motor symptoms of patients with RLS by examining and integrating previous randomized controlled trials done on the subject. Methods: A thorough search in international and local databases of available randomized controlled studies of pregabalin for primary RLS were done from January 1940 until August 2015. Results: There were 3,708 studies identified, 4 studies meeting the inclusion criteria. Three independent reviewers assessed the studies for eligibility. Pooled results showed significant difference in the change in the International Restless Legs Syndrome scale score of -4.47 (CI -6.11 – -2.83), improvement in Clinical Global Impressions responders, total sleep time, sleep efficiency, sleep quality, change in wake time after sleep onset, and number of awakenings, all favoring pregabalin compared to placebo. There is no significant difference in the quality of life for pregabalin when compared to placebo. Adverse events of dizziness, somnolence, headache, and dry mouth were significantly increased (RR 13.18, 7.21, 3.47, and 5.27 respectively) in the 551 participants of the pregabalin group.Conclusion: This meta-analysis indicates that pregabalin appears to be efficacious in the improvement of symptoms and sleep architecture of patients with RLS.

Delusional infestation. ekbom's syndrome in a 53-year old woman. case report

ABSTRACT Introduction: Delusional infestation is a rare psychiatric disorder defined as a condition in which the patient has the unshakable belief and perception of being infested with parasites. Its treatment is difficult, and frequently includes antipsychotic medications (such as olanzapine or aripiprazole). Non-pharmacological treatment, particularly psychotherapy, can be used for less severe cases. Dermatologists and psychiatrists must take a multi-disciplinary approach (preferably in a psycodermatology dedicated clinic) since this type of patients sometimes refuse treatment. Case description: A 53-year-old female businesswoman describes a clinical history of five years of visual hallucinations, depressive symptoms, and generalized pruritus, along with the use of toxic substances to "clean" her skin and cloths. She reports similar symptoms in some relatives but they were not evaluated. Blood tests and analyses of the "specimen" brought by the patient were performed, yielding negative results. The patient had never been assessed by any specialist, and showed disoriented during the consultation. Follow-up was not possible due to the reluctance of the patient to follow the indications and seek psychiatric treatment. Moreover, the patient did not respond to further communication attempts. Discussion: Delusional infestation is an uncommon disease that endangers the patients and the people around them. Its treatment is difficult and long, and not conducting proper follow-up is a great risk. Its prevalence and incidence is variable and generally unknown. It can affect the patient, their next of kin, pets or the environment, and the "pathogen" can be a living organism or an inanimate object. Conclusion: This case is important as it shows the hardships of treatment, adequate follow-up and care, as well as the need to improve how these patients are approached. Additionally, both classical and uncommon signs and symptoms could be observed as the patient stated that her relatives were affected (possible delusional infestation by proxy).

Trastornos de sueño en residentes de Atahualpa / Sleep disorders in Atahualpa residents

RESUMEN Es probable que los problemas de salud relacionados con los trastornos del sueño se encuentren en aumento en las zonas rurales de América Latina, en parte relacionados con los cambios en el estilo de vida, el trabajo con turnos nocturnos y otros factores. Sin embargo, poco se sabe sobre la prevalencia de estas condiciones en lugares rurales remotos. En el Proyecto Atahualpa, hemos investigado los trastornos del sueño utilizando instrumentos de campo estandarizados asociados con tecnología sofisticada como la polisomnografía. Una mala calidad del sueño se ha asociado con fragilidad y con la presencia de marcadores de neuroimagen de enfermedad de vasos cerebrales y atrofia cortical global. Por el contrario, la ingesta dietética de pescado oleoso se asoció con una mejor calidad del sueño. También se ha investigado la prevalencia y algunos correlatos del síndrome de las piernas inquietas (enfermedad de Willis-Ekbom) y se encontró una prevalencia relativamente superior a la descrita en la mayoría de las regiones tropicales, así como la asociación de esta afección con el estrés psicológico. Finalmente, un informe preliminar muestra una elevada prevalencia de apnea obstructiva moderada a severa en los residentes de Atahualpa de ≥60 años (27%) y su correlación con daño subcortical difuso de origen vascular. Se necesitan más estudios para comprender mejor las consecuencias de los síntomas relacionados con el sueño en dichas poblaciones.

ABSTRACT Health problems related to sleep disorders are likely on the rise in rural areas of Latin America, partly related to changes in life style, shift work, and other factors. However, little is known on the burden of these conditions in remote rural settings. In the Atahualpa Project, we have investigated sleep disorders using standardized field instruments associated with sophisticated technology such as polysomnography. A poor sleep quality has been associated with frailty and with the presence of neuroimaging markers of cerebral small vessel disease and global cortical atrophy. On the contrary, dietary intake of oily fish was associated with a better sleep quality. We have also investigated the prevalence and some correlates of the restless legs syndrome (Willis-Ekbom disease), and found a prevalence relatively higher than that described in most other tropical regions, as well as the association of this condition with psychological stress. Finally, a preliminary report shows a high prevalence of moderate-to-severe obstructive sleep apnea in Atahualpa residents aged ≥60 years (27%) and its correlation with diffuse subcortical damage of vascular origin. Further studies are needed to better understand consequences of sleep-related symptoms in underserved populations.

Parasitosis ilusoria intestinal y dermatológica: casos clínicos / Delusional parasitosis intestinal and dermatological: clinical cases

Illusory parasitosis, better known as delusional parasitosis, is a neuropsychiatric syndrome in which patients have the belief of suffering a parasitic disease, that can not be demonstrated after an exhaustive medical study. These patients are characterized by being polyconsultants in different medical specialties and, many of them, have antecedents of psychiatric disorders, some of them undiagnosed. Knowing the existence of the clinical picture, diagnosing early and empathizing with the patient, could give to clinician some clues for a timely and assertive psychiatric referral, and improve patient adherence to the proposed treatment.

La parasitosis ilusoria, más conocida como delusión parasitaria, es un síndrome neuropsiquiátrico donde los pacientes tienen el convencimiento de padecer una infestación parasitaria, que no puede ser demostrada tras un exhaustivo estudio médico. Estos pacientes se caracterizan por ser policonsultantes en distintas especialidades médicas y, muchos de ellos, poseen antecedentes de trastornos psiquiátricos, algunos de ellos no diagnosticados. Conocer la existencia del cuadro, diagnosticar precozmente y empatizar con el paciente, pueden dar al médico clínico algunas claves para una derivación psiquiátrica oportuna y asertiva, y mejorar la adherencia del paciente al tratamiento propuesto. Se presentan cuatro casos clínicos que consultaron por esta extraña condición.

Síndrome de Ekbom: a propósito de un caso / Ekbom syndrome: apropos of a case

El síndrome de Ekbom o delirio de parasitosis es una condición psiquiátrica infrecuente cuyo síntoma principal es la idea delirante de estar infestado con organismos vivientes, como parásitos, bacterias, virus, insectos o gusanos. Se presenta el caso de un varón de 34 años con un cuadro compatible con este síndrome. Se revisa brevemente la literatura disponible y se realiza una correlación teórico-clínica con los síntomas del paciente, y se concluye que el paciente sufría un síndrome de Ekbom de tipo primario y mixto.

The Ekbom syndrome or delusional parasitosis is an uncommon psychiatric condition, in which the main symptom is the delusion of being infested with living organisms such as parasites, bacteria, virus, bugs or worms. The case is presented of a 34 year-old man with symptoms compatible with the syndrome. The available literature is briefly reviewed and theoretical correlation with clinical symptomatology is made. The patient had a primary and mixed Ekbom syndrome.

Saint John's wort, an herbal inducer of the cytochrome P4503A4 isoform, may alleviate symptoms of Willis-Ekbom's disease

OBJECTIVE: Certain drug classes alleviate the symptoms of Willis-Ekbom's disease, whereas others aggravate them. The pharmacological profiles of these drugs suggest that drugs that alleviate Willis-Ekbom's disease inhibit thyroid hormone activity, whereas drugs that aggravate Willis-Ekbom's disease increase thyroid hormone activity. These different effects may be secondary to the opposing actions that drugs have on the CYP4503A4 enzyme isoform. Drugs that worsen the symptoms of the Willis-Ekbom's disease inhibit the CYP4503A4 isoform, and drugs that ameliorate the symptoms induce CYP4503A4. The aim of this study is to determine whether Saint John's wort, as an inducer of the CYP4503A4 isoform, diminishes the severity of Willis-Ekbom's disease symptoms by increasing the metabolism of thyroid hormone in treated patients. METHODS: In an open-label pilot trial, we treated 21 Willis-Ekbom's disease patients with a concentrated extract of Saint John's wort at a daily dose of 300 mg over the course of three months. RESULTS: Saint John's wort reduced the severity of Willis-Ekbom's disease symptoms in 17 of the 21 patients. CONCLUSION: Results of this trial suggest that Saint John's wort may benefit some Willis-Ekbom's disease patients. However, as this trial was not placebo-controlled, the extent to which Saint John's wort is effective as a Willis-Ekbom's disease treatment will depend on future, blinded placebo-controlled studies. .

El síndrome de Ekbom: un trastorno entre la dermatología y la psiquiatría / Ekbom syndrome: a condition between dermatology and psychiatry

Introducción: El síndrome de Ekbom o delirio de parasitosis (DP) representa una psicosis monosintomática, poco frecuente, caracterizada por la creencia firme, por parte de quien la padece, de que está infestado, en contra de toda evidencia, por insectos, gusanos o piojos que habitan y dañan su piel. Los pacientes pueden ver seriamente afectado el trabajo diario o la vida social. Objetivos: Estudiar en profundidad a los pacientes con DP y aprender más de ellos. Método: Se aportan cinco casos: tres mujeres y dos hombres. Resultados: La duración media de los síntomas, hasta que llegaron por primera vez a la consulta, fue de 10 meses. Dos pacientes presentaban ideas delirantes de infestación cutánea y oral. Sentían “lagartijas” o pequeños organismos en sus bocas. Todos los pacientes fueron tratados con pimozida, pero solamente dos remitieron completamente. Posteriormente, dos pacientes se trataron con sulpiride y alcanzaron una remisión total. A otro paciente se le administró risperidona y remitió parcialmente. Los pacientes se evaluaron a los tres, seis y doce meses después del tratamiento. Conclusiones: Se resaltan las dificultades en el diagnóstico y en la elección de la terapéutica adecuada por parte del dermatólogo, quien se enfrenta al dilema de manejar un trastorno psiquiátrico en el campo dermatológico. Además, se ha comprobado que actualmente sólo existe un caso publicado en que coexisten ideas delirantes de infestación en piel y cavidad oral...

Introduction: Ekbom syndrome or delusional parasitosis (DP) represents a rare mono-symptomatic psychosis characterized by the delusional belief of the patient against all evidence, that he is infested by insects, worms or lice that damage his skin. Daily work and/or social activities may be seriously compromised. Objectives: To review cases of patients with DP in order to learn from them. Method: Five cases (3 men and 2 women) are reported. Results: Mean duration of symptoms at the time of the first assessement was 10 months. Two of the patients had delusions of oral and skin parasitosis. They felt small lizards and/or small organisms in their mouths. All of them were treated with pimozide, but only one had complete remission. Later, two of them were treated with sulpiride and achieved total remission. Risperidone was given to one patient, resulting in partial remission. All the patients were evaluated at 3, 6 and 12 months post-treatment. Conclusions: These findings highlight the difficulties encountered in diagnosing DP, in the lack of acceptance of the treatment by the patient, and in choosing the right psychotropic medication by the dermatologist who faces the dilemma of managing a psychiatric condition in a dermatological setting. To the best of our knowledge, there is only one previous report of coexisting delusions of oral and skin parasitosis to date...

Delírio de infestação parasitária e transtorno bipolar: relato de caso / Delusional parasitosis and bipolar disorder: case report

O presente relato tem por objetivo descrever o caso de uma paciente portadora de delírio de infestação parasitária comórbido com transtorno bipolar. Trata-se de paciente portadora de transtorno bipolar há mais de 30 anos e que se encontrava com quadro psíquico estabilizado e sem alterações do humor durante as consultas psiquiátricas. Em uma das suas avaliações periódicas, começou a se queixar da presença de vermes que estavam infestando seu corpo, o que já vinha ocorrendo há 8 anos. Estava em uso de carbonato de lítio e não aceitou tomar o antipsicótico prescrito porque já experimentara efeito colateral com essa classe de medicamentos. A associação entre delírio de infestação parasitária e transtorno bipolar é rara, e os autores encontraram apenas um caso semelhante descrito na literatura médica internacional.

The objective of the present report is to describe the case of a patient with delusional parasitosis comorbid with bipolar disorder. The patient had been diagnosed with bipolar disorder over 30 years ago and her mental state was stable without any mood disturbances detected during psychiatric visits. During one of her periodic evaluations, the patient started to complain that worms were infesting her body, which had been occurring for the past 8 years. She was taking lithium carbonate and refused to use an antipsychotic because she had experienced side effects after using this class of drugs. The association between delusional parasitosis and bipolar disorder is rare, and we found only one similar case described in the literature.

Delirio de parasitosis: a propósito de doce casos / Delusion of parasitosis: report of twelve cases

En el presente trabajo se da cuenta de la historia del síndrome delirante crónico conocido como "delirio de parasitosis o síndrome de Ekbom", sus principales características clínicas, evolutivas, la ubicación nosográfica y las estrategias terapéuticas utilizadas. Los hallazgos de la principal literatura publicada se comparan con la experiencia de los autores al haber estudiado doce pacientes portadores de esta sintomatología. Asimismo, se indaga acerca de la posible conexión con otros cuadros psicopatológicos, más específicamente con el espectro obsesivo-compulsivo.

In this paper, the history of the chronic delusional syndrome known as delusional parasitosis or Ekbom syndrome is reviewed as well as its main clinical characteristics, evolution, nosographic position and therapeutic approaches. The findings in the published literature are compared with the clinical experience of the authors who have studied twelve cases. The possible connection with other mental diseases, specifically Obsessive Compulsive Spectrum, is evaluated.

Síndrome de Ekbom acompanhada de automutilação / Ekbom's syndrome followed by self-mutilation

O delírio parasitário (ou síndrome de Ekbom) é uma condição rara, onde o paciente apresenta uma forte convicção de que está infestado por pequenos parasitas ou organismos. Muitas vezes, os delírios são tão intensos que levam esses pacientes à automutilação. Relatamos aqui um caso de um senhor de 67 anos, isolado socialmente, solteiro, apresentando delírio parasitário em região perineal, culminando em lesões por automutilação.

Delusional parasitosis (or Ekbom's syndrome) is a rare condition, in which the patient has a strong conviction that he or she is infested by small parasites or organisms. These delusions are often so intense that they lead the patient to self-mutilation. We report a case of a 67-year-old man, socially isolated, single, with delusional parasitosis in the perineal area, culminating in self-mutilation lesions.
