BACKGROUND: Delusional parasitosis is infrequently seen in hospital-based consultation-liaison psychiatry. AIMS: Although there are many publications on delusional parasitosis, this report reviews a unique case that was diagnosed during a hospital admission and treated over the next 36 months. METHOD: Case report and literature review. RESULTS: This case report describes a 65-year-old man who was diagnosed with delusional parasitosis during a hospital admission for congestive heart failure and acute kidney injury...

Matrix metalloproteinase 9 (MMP-9) has recently emerged as a molecule that contributes to pathological synaptic plasticity in schizophrenia, but explanation of the underlying mechanisms has been missing. In the present study, we performed a phenotype-based genetic association study (PGAS) in > 1,000 schizophrenia patients from the Göttingen Research Association for Schizophrenia (GRAS) data collection and found an association between the MMP-9 rs20544 C/T single-nucleotide polymorphism (SNP) located in the 3'untranslated region (UTR) and the severity of a chronic delusional syndrome...

AIM: To evaluate the effect of changing therapy from typical antipsychotics to the atypical antipsychotic risperidone in the treatment of difficult-to-treat residual psychotic symptoms. MATERIAL AND METHODS: The study included 15 patients, 8 men and 7 women, mean age 49.1±10.25 years, diagnosed with paranoid schizophrenia, partial remission (ICD-10 F20.04). At the beginning all participants received regular maintenance antipsychotic therapy with typical antipsychotics...

Delusional parasitosis (DP) or Ekbom's disease is a rare psychiatric condition where the sufferers have a firm-fixed belief of insects crawling over their skin. The condition may be primary monosymptomatic hypochrondrical delusion or secondary to an underlying psychiatric or organic condition. We present two cases of elderly men presenting with classical symptomatology of DP, which is found to be secondary to postherpetic neuralgia following an acute episode of shingles or herpes zoster infection. One patient responded to a combination of antipsychotic, olanzapine, and pregabalin, used for neuropathic pain, and the other patient responded completely with medications used for neuropathic pain only without any antipsychotic use...

Objective: To describe a rare case of a patient who developed psychotic symptoms after a right stroke that disappeared with antipsychotic treatment, but appears to need low-dose maintenance antipsychotic therapy. Case description: A 65-year-old man presented at the psychiatric emergency service with a history of persistent delusional jealousy, visual illusions and agitation with onset about 1 month after a right posterior cerebral artery ischemic stroke. These symptoms only disappeared with therapeutic dosages of an antipsychotic drug (3 mg/day of risperidone)...

OBJECTIVE: The aim of this cross-sectional study was to identify if there was a specific difference between patients with functional dystonia (DysF) and those with adult-onset, isolated idiopathic ("primary") dystonia (DysP) in terms of psychiatric disorders, psychological stressor, dissociation correlates, and personality traits. METHODS: Thirty-nine clinically definite DysF and 30 DysP patients matched by age, gender and dystonia distribution underwent psychiatric interview based on DSM-5 criteria and additional testings for global cognitive and psychiatric functions (Mini-Mental State Examination, Hamilton Depression and Hamilton Anxiety Rating Scale, Apathy Scale, Somatoform Dissociation Questionnaire-20, Dissociative Experiences Scale II, and the five-dimensional Revised Neuroticism-Extroversion-Openness Personality Inventory)...

BACKGROUND: Head-to-head trials to guide antipsychotic treatment choices for paediatric psychosis are urgently needed because extrapolations from adult studies might not be implementable. In this superiority trial with two-sided significance testing, we aimed to compare the efficacy and safety of quetiapine-extended release (quetiapine-ER) versus aripiprazole in children and adolescents with first-episode psychosis, to determine whether differences between the two treatments were sufficient to guide clinicians in their choice of one drug over the other...

OBJECTIVE: To contribute to a better differential clinical categorisation of delusional disorder (DD) versus schizophrenia (SZ) and to add and complete evidence from previous clinical studies of DD compared to schizophrenia. METHODS: A cross-sectional study using a clinical sample of 275 patients (132 patients with DD) was studied. Patients were consecutively attending public clinics located in urban and rural areas in both Andalusia and Catalonia (Spain). All participants met DSM-IV diagnostic criteria for either DD or SZ...

Psychotic-like experiences (PLEs) in adolescence are found to be risk factors for later mental disorders. Previous research has also found that childhood trauma has a positive correlation with mental health problems. However, few studies have focused on the relationship between them, especially in adolescence and early adulthood. A total of 9122 students (age between 10 and 23.3) were surveyed and assessed with the positive and depressive subscales of the Community Assessment of Psychic Experiences and the Trauma History Questionnaire...

BACKGROUND: To characterize the yearly incidence, diagnostic distribution, and neuro-radiologic findings in patients aged over 60 years, referred to psychiatric treatment with first episode psychosis (FEP). METHODS: A computerized search, including all patients referred to psychiatric treatment during 12 consecutive months with a de novo diagnosis of psychosis was performed in the Helsinki region catchment area with 1.2 million inhabitants. Diagnoses based on hospital records were made by a group of one neurologist and three psychiatrists...

Lifetime prevalence of psychotic disorders varies widely across studies. Epidemiological surveys have rarely examined prevalences of specific psychotic disorders other than schizophrenia, and the majority used a single-phase design without employing clinical reappraisal interview for diagnostic verification. The current study investigated lifetime prevalence, correlates and service utilization of schizophrenia-spectrum, affective, and other non-affective psychotic disorders in a representative sample of community-dwelling Chinese adult population aged 16-75 years (N = 5719) based on a territory-wide, population-based household survey for mental disorders in Hong Kong...

INTRODUCTION: Lithium is known to cause certain neurological deficits. However, reports of aphasia secondary to lithium toxicity are scant. We report the case of a 70 year old African American woman with a history of schizoaffective disorder and mild dementia who developed transient intermittent aphasia secondary to lithium toxicity. METHODS: Patient was admitted because of agitation, delusional behavior, and loud and pressured speech. Her previous medications included divalproex sodium 500mg po bid, valproic acid 250mg po qd, risperidone 3...

The skin and psyche are intimately related with various skin diseases caused by or resulting in psychiatric disturbances. Pruritus is a commonly reported symptom in psychiatric patients, and likewise psychiatric co-morbidities, including anxiety and depression, are frequently seen in chronic pruritus patients. Primary psychodermatologic conditions, such as somatic symptom disorder, dermatitis artefacta, obsessive-compulsive and related disorders (excoriation disorder and prurigo nodularis), delusional infestation, and substance use disorder, can all induce significant pruritus in patients, severely affecting their quality of life...

Objectives The objective of this study was to discuss jinn possession in Muslim culture, and the importance of understanding cultural differences in mental health. Conclusion It is important to understand cultural and religious differences in psychiatry, as it affects the way patients perceive and attribute symptoms. It also helps clinicians to reach an accurate diagnosis and provide appropriate treatments. Beliefs about jinn possession should not automatically be regarded as delusional. In alleged cases of jinn possession, clinicians should consider all the biopsychosocial, cultural and spiritual factors that are unique to the individual...

Influential models of schizophrenia suggest that patients experience incoming stimuli as excessively novel and motivating, with important consequences for hallucinatory experience and delusional belief. However, whether schizophrenia patients exhibit excessive novelty value and whether this interferes with adaptive behaviour has not yet been formally tested. Here, we employed a three-armed bandit task to investigate this hypothesis. Schizophrenia patients and healthy controls were first familiarised with a group of images and then asked to repeatedly choose between familiar and unfamiliar images associated with different monetary reward probabilities...

The present study aimed to explore the latent structure of the 21-item Peters et al. Delusions Inventory (PDI-21) and to test the invariance of its factor structure over time and across samples. The PDI-21 was administered in two samples; one consisting of 1655 undergraduate students investigated in three waves, each separated by six months; and another consisting of 196 outpatients with schizophrenia. Exploratory factor analysis was performed to explore the internal structure of the PDI-21 based on number of beliefs and the grand total scores separately...
