The Diagnostic Workup, Screening, and Treatment Approaches for Patients with Delusional Infestation

Delusional infestation (DI) is a psychiatric disorder defined by the fixed, false belief that one has been infested by an organism without evidence to support this. Patients may present with skin lesions and report abnormal cutaneous sensations. The diagnostic workup for patients presenting with delusional infestation is essential to ensuring accurate diagnosis in ruling out other explanations for symptoms and investigating potential secondary causes of DI. In addition to a comprehensive history and physical examination, laboratory workup should be considered depending on the clinical picture. Antipsychotic medications are the most common drugs used in management of adults with DI and tailor the choice of treatment according to patient characteristics. This article serves as a guide for dermatologists, psychiatrists, and other clinicians as it reviews the workup and screening that should be considered when managing a patient with delusional infestation and subsequent treatment protocols once the diagnosis has been made.

Psychodermatology in Lithuania. A survey on knowledge, awareness, and practice patterns in Lithuanian dermatovenereologists

The aim of this study was to evaluate the knowledge, awareness, and practice patterns of Lithuanian dermatovenereologists regarding psychocutaneous medicine. An online survey questionnaire was distributed to the members of the Lithuanian Association of Dermatovenereologists and to dermatovenereologists through public and private healthcare institutions in Lithuania. The questionnaire consisted of questions related to dermatovenereologists' awareness, knowledge, experience, and training needs regarding psychocutaneous disorders. 50% of respondents reported having a good or excellent understanding and knowledge of psychodermatology, and 42% feel prepared to consult psychodermatology patients. 54% of doctors rated their preparedness to prescribe psychopharmacological treatment as poor. The most frequent diagnoses referred to mental health professionals were dermatitis artefacta, acne excoriée, other self-inflicted dermatoses, trichotillomania, and pruritus. The most common course of action with patients at high risk of suicide or other acute psychiatric condition was trying to provide psychological support during dermatovenereology consultation. The most frequent management tactic for patients with chronic psychological problems was a referral to a psychiatrist. 85% of all respondents would participate in educational events about psychodermatology. 70% expressed interest in events about psychopharmacological treatment in dermatology. Lithuanian dermatovenereologists have a good understanding and knowledge of psychodermatology and are willing to further their education in this field. However, some gaps remain. Many doctors reported feeling poorly prepared to administer psychopharmacological treatment to their patients and there seems to be a lack of formal training in psychodermatology in Lithuania.

Alexithymia and Cutaneous Disease Morbidity: A Systematic Review

BACKGROUND

Alexithymia is a psychological construct that describes one's difficulty in understanding and describing their own emotions as well as differentiating feelings from bodily signals of arousal. In the general population, alexithymia's prevalence is approximately 10%. Alexithymia may act as a triggering factor for many medical and psychiatric disorders. In patients with physical disease, alexithymia's prevalence reaches up to 63%. Additionally, alexithymia is associated with worse outcomes and heightened psychosocial comorbidities.

OBJECTIVE

This review continues where an earlier review (Willemsen, 2008) left off to (1) clarify alexithymia's prevalence in dermatology patients and (2) further investigate alexithymia's impact on disease burden, psychosocial comorbidities, and treatment.

METHODS

Systematic searches on alexithymia and dermatologic conditions were conducted using PubMed, Embase, PsycInfo, and Web of Science databases from March 8, 2021, to March 12, 2021. Data from eligible publications, which were full-text, clinical studies published after September 1, 2008, and available in English, were extracted by two medical students and summarized.

RESULTS

Despite a small number of publications (n = 37), data showed a markedly greater prevalence and severity of alexithymia in patients with alopecia, vitiligo, psoriasis, hidradenitis suppurativa, atopic dermatitis, chronic idiopathic urticaria, and primary focal hyperhidrosis compared to healthy controls. Further, data consistently demonstrate a complex interplay between alexithymia, disease burden, and psychosocial comorbidity.

CONCLUSIONS

Identifying and addressing alexithymia in dermatology patients may improve treatment outcomes, associated comorbidities, and health-related quality of life.
