Ekbom syndrome is a mental disorder in which the patient has the monothematic delusion of being infected by parasites. It is an uncommon condition that was initially studied by dermatologists. The exactly etiology is unknown to date, though several causes have been proposed, including metabolic diseases (among other physical causes), psychiatric disorders, drugs, etc. Research has now found a relationship between drug abuse and psychotic symptoms, which appear to be due to altered levels of dopamine at the receptor level. In this article we review the clinical features of the condition and present the case report of an intravenous methylphenidate abuser who developed a delusion of parasitosis.Key words: Ekbom, parasitosis, infestation, delusion, methylphenidate.El Síndrome de Ekbom es un trastorno mental en que el paciente tiene la convicción delirante monotemática de estar infectado por parásitos. Se trata de un cuadro poco frecuente, que inicialmente fue estudiado por dermatólogos. No se conoce exactamente la etiopatiogenia hasta el momento, si bien se han objetivado diversas causas: enfermedades metabólicas (entre otras causas físicas), cuadros psiquiátricos, fármacos, etc. En la actualidad, se ha encontrado relación entre el consumo de tóxicos y cuadros psicóticos, que parecen debidos a la alteración de la Dopamina a nivel de sus receptores. En este artículo realizamos una revisión del cuadro clínico y presentamos el caso clínico de un paciente consumidor de metilfenidato intravenoso que desarrolla un delirio de infestación.Palabras clave: ekbom, parasitosis, infestación, delirio, metilfenidato.

Cognitive‐affective drivers of fixation in threat assessment

Pathological fixation -preoccupation with a person or a cause that is accompanied by deterioration in social and occupational functioning -has been found to precede most cases of targeted violence. It is clinically observed and theorized to have three different cognitive-affective drivers: delusion, obsession, or extreme overvalued belief. Each driver is explained, and case examples are provided in the context of threat assessment. Extreme overvalued belief as a new concept is discussed in detail, both its historical provenance and its demarcation from delusions and obsessions. Threat management for each separate cognitive-affective driver is briefly summarized, based upon current clinical findings and research. Emphasis is placed upon understanding both the categorical and dimensional nature (intensity) of these cognitive-affective drivers, and suggested guidelines are offered for the assessment of such in a clinical examination by a forensic psychiatrist or psychologist. | INTRODUCTIONPathological fixation -preoccupation with a particular person or cause that is accompanied by deterioration in

Does aversion to insects affect insecticide use? An elusive answer calls for improved methods in biophobia research

Insecticides are commonly used to control insects and other arthropods in homes (hereafter collectively referred to as ‘insects’). Although aversion to insects might encourage the use of insecticides, it is unclear whether such feelings truly influence the decision to use insecticides. We investigated the connection between feelings of disgust towards insects and the use of household insecticides. Our aim was to uncover the unexplored emotional drivers of insecticide use, in order to provide insights that might help develop new programmes to reduce exposure to household insecticides. We conducted an online survey (n = 2500) that focussed on insecticide use and disgust feelings towards six species commonly found in homes (cockroaches, ants, spiders, mosquitoes, flies and centipedes). Respondents rated their level of disgust towards these species and reported various beliefs and practices related to household insects and insect control. Approximately 70% of respondents expressed strong disgust towards these species (ratings of 6 or 7 on a scale of 1–7). More than half (53.3%) reported using aerosol insecticides in their homes in the 6 months prior to the survey. Path analyses highlighted several factors that influenced insecticide use, including infestation level, disgust intensity, lack of knowledge about arthropods and aversion to chemicals. However, the observed effect sizes were modest, particularly regarding the influence of disgust on insecticide use, which somewhat constrains our study's contribution to the understanding of the motivators driving household insecticide use. We explain how our findings potentially reflect a critical methodological limitation in the standard methods commonly used for measuring aversion in biophobia (fear of nature) research. This limitation originates from the fact that highly aversive animals often provoke extreme reactions from most participants, resulting in a very low data variation that hinders data analysis. We address this concern in the context of our findings and propose potential solutions that could pave the way for future research on how attitudes towards highly aversive animals affect individuals, society, and the relationships between people and nature.
