P-885 - Morgellons disease and / or psychosis

Background Delusional infestation is a primary psychiatric disorder characterized by a somatic‐type delusional disorder (primary delusional infestation) that may lead to self‐induced cutaneous lesions which are often difficult to recognize and treat properly. It may be also secondary to other psychiatric disorders, medical diseases, or substance abuse. Aims This review will describe prevalence, common clinical features, different clinical presentations, differential diagnoses, and treatment recommendation. Special focus has been put on psychological aspects. Methods We conducted a literature search on PubMed from January 2001 to June 2020 with the search terms of delusional parasitosis, delusional infestation, psychological, Reference lists of identified articles were examined for further relevant studies. The search was limited to English language articles. No specified quality criteria were used for study inclusion. Results The clinical manifestations of delusional infestation are very important in the differential diagnosis and its psychological implications and management perspectives. Conclusion This article presents an update regarding the clinical aspects and treatment options of delusional infestation in order to provide an up‐to‐date review for dermatologists and general practitioners.

Delusional Parasitosis (DP) is a Psychocutaneous disorder that was 1st described in the late 17th century in France. The etiology is neuro-chemical. The classic “matchbox” and “specimen” signs are characteristic. Management is via a multidisciplinary approach. This review paper is based on detailed systematic review of literature via an up-to-date evidence based approach. This paper reviews: Historical facts, epidemiology, pathogenesis, clinical features, subtypes, associated diseases, psychosocial impact, economic considerations and management. An exhaustive search strategy was utilized across five medical literature databases led by 62 pre-specified keywords, followed by database-specific filters’ application to scrutinize the hierarchy of literature, from systematic reviews and randomized controlled trials to medical papers with weak evidence. Forty references were utilized to extract the most relevant data. This review article is level II-3 (level of evidence); it will enable the researcher to obtain a perspective of DP, upon which an original research can be developed.Asian Journal of Medical Sciences Vol. 7(3) 2016 1-8

“…Repressing and storing feelings associated with unpleasant or painful memories has been a key topic in psychological tradition. Unravelling and communicating the distressing information we keep to ourselves has long been considered a healthy habit ( Frattaroli, 2006 ), and has been associated with improvements in mental health and recovery ( Bistrović et al, 2013 ). As a method to draw and shape painful past events, emotional disclosure is commonly achieved through a linguistic avenue, either written or verbalised ( Pennebaker, 1993 ; Lepore and Smyth, 2002 ).…”

Processing negative autobiographical memories in a foreign language

The use of a foreign language has been introduced in the clinical setting as a form of emotional distance to help deal with negative experiences. However, the evidence of foreign language reducing emotionality during processing negative events is still scarce. This study aims to test whether the description and processing of a traumatic or highly emotional event in a foreign language could modulate the strength of the connection between traumatic symptomatology and emotional reaction. For this purpose, a sample of 128 healthy participants completed a series of questionnaires via an online platform. Firstly, their levels of distress, arousal and valence were assessed in their native language. Secondly, they were assigned to either the native language or the foreign language group and described a negative childhood event in the assigned language (English or Spanish), followed by five questions for processing the event. Next, their emotionality was assessed again in their native language. Finally, a questionnaire of traumatic stress symptoms and an avoidance scale were completed. Results showed that the relationship between traumatic symptomatology and emotionality was moderated by the language of processing the negative event. Specifically, traumatic symptomatology was more strongly associated with distress and arousal change when the processing task was performed in the native language. These findings suggest the influence of a foreign language on emotional reactivity when a negative experience is processed, which could be an essential tool in the treatment of disorders related to stress and trauma.
