“…The respective diagnostic ICD-10 and DSM-IV-TR codes have been included in the table to increase practical use. This distinction of primary and secondary forms of DI has become the most common classification (76,94,95,178). It has been used and proven in clinical practice and in research.…”

“…Most authors recommend a graded pathway with two major steps for optimized clinical management of patients with DI (76,234,280,351). It has to be stressed, however, that all of these clinical pathways for DI have not been evaluated in terms of sensitivity, specificity, or cost-efficiency and represent expert opinion only.…”

SUMMARY This papers aims at familiarizing psychiatric and nonpsychiatric readers with delusional infestation (DI), also known as delusional parasitosis. It is characterized by the fixed belief of being infested with pathogens against all medical evidence. DI is no single disorder but can occur as a delusional disorder of the somatic type (primary DI) or secondary to numerous other conditions. A set of minimal diagnostic criteria and a classification are provided. Patients with DI pose a truly interdisciplinary problem to the medical system. They avoid psychiatrists and consult dermatologists, microbiologists, or general practitioners but often lose faith in professional medicine. Epidemiology and history suggest that the imaginary pathogens change constantly, while the delusional theme “infestation” is stable and ubiquitous. Patients with self-diagnosed “Morgellons disease” can be seen as a variation of this delusional theme. For clinicians, clinical pathways for efficient diagnostics and etiology-specific treatment are provided. Specialized outpatient clinics in dermatology with a liaison psychiatrist are theoretically best placed to provide care. The most intricate problem is to engage patients in psychiatric therapy. In primary DI, antipsychotics are the treatment of choice, according to limited but sufficient evidence. Pimozide is no longer the treatment of choice for reasons of drug safety. Future research should focus on pathophysiology and the neural basis of DI, as well as on conclusive clinical trials, which are widely lacking. Innovative approaches will be needed, since otherwise patients are unlikely to adhere to any study protocol.

Delusions of Pregnancy with Post-Partum Onset: An Integrated, Individualized View

et al. 2009

-Background and Objectives: Bizarre hypochondriacal delusion is an important content of delusion of pregnancy during post-partum period.Methods: Here we report two cases with postpartum delusion of pregnancy; one with pre-existing schizophrenia and another one with family history of pseudocyesis and schizoaffective disorder but with no pre-existing psychiatric illness.Results: Nosological, phenomenological and aetiological issues are discussed. In the context of novel deficit-and motivational theories of delusion formation we provide an integrated view of the reported cases.Conclusions: The complexity of the delusion of pregnancy should be considered in the treatment planning-particularly in the post-partum period.

Ekbom Syndrome: A Delusional Condition of “Bugs in the Skin”

Entomologists estimate that more than 100,000 Americans suffer from "invisible bug" infestations, a condition known clinically as Ekbom syndrome (ES), although the psychiatric literature dubs the condition "rare." This illustrates the reluctance of ES patients to seek mental health care, as they are convinced that their problem is bugs. In addition to suffering from the delusion that bugs are attacking their bodies, ES patients also experience visual and tactile hallucinations that they see and feel the bugs. ES patients exhibit a consistent complex of attributes and behaviors that can adversely affect their lives.
