RESUMEN
We conducted a retrospective chart review to examine the gender differences in young onset Persistent Delusional Disorder (PDD) subjects (N = 236) with onset of illness before the age of 30 years. Gender differences in marital and employment status were significant (p-0.001). Delusion of infidelity and erotomania were more common in females, while males had more body dysmorphic and persecutory delusions (X2-20.45, p-0.009). Males had more substance dependence (X2-21.31, p < 0.001), as well as a family history of substance abuse and PDD (X2-18.5, p < 0.01). To conclude, gender differences in PDD comprised some psychopathology, co-morbidity, and family history among those with young onset PDD.

The fact that delusional disorder (DD) received minimal research attention indicates the need for descriptive studies that will better delineate the clinical and socio-demographic characteristics of DD. We conducted a chart review descriptive study in a tertiary hospital from Turkey. A total of 99 cases of DD were identified through hospital registry system. 57 were male (57.6%), and mean age at first admission was 49.34±13.49. The most common type of DD was persecutory (36.4%), followed by jealous type (28.3%), mixed type (18.2%), and somatic type (16.2%). Jealous type DD patients were more likely to be married, and mixed type DD patients were more likely to be divorced. The presence of hallucinations was significantly associated with history of hospitalization. About one-tenth of the patients had a family history of psychotic spectrum disorder. Comorbid depressive disorder was present in 42.9% of the patients, whereas only 9.2% had comorbid anxiety disorder. Depressive disorder comorbidity in DD seems to be associated with continued treatment for longer periods of time in psychiatry services. While most of our data were comparable with the literature on DD, our divergent findings like higher rates of male patients and jealous type of the disorder might be attributed to the cultural and geographical factors. This situation points out that future research with larger populations and from different regions would contribute to better understanding of clinical and socio-demographical characteristics of delusional disorder.

This study estimated the prevalence and incidence rate of schizophrenia, schizotypal, and delusional disorders (SSDD) in Korea from 2008 to 2017 and analyzed the hospital admission rate, re-admission rate, and hospitalization period. It used the Korean nationwide National Health Insurance Service claims database. SSDD patients who had at least one visit to Korea's primary, secondary, or tertiary referral hospitals with a diagnosis of SSDD, according to the International Classification of Diseases, 10th Revision (ICD-10), were identified as SSDD cases if coded as F20-F29. Data were analyzed using frequency statistics. Results showed that the 12-month prevalence rate of SSDD increased steadily from 0.40% in 2008 to 0.45% in 2017. Analysis of the three-year cumulative prevalence rate of SSDD showed an increase from 0.51% in 2011 to 0.54% in 2017. In 2017, the five-year cumulative prevalence rate was 0.61%, and the 10-year cumulative prevalence rate was 0.75%. The hospital admission rate among SSDD patients decreased from 2008 (30.04%) to 2017 (28.53%). The incidence of SSDD was 0.05% and no yearly change was observed. The proportion of SSDD inpatients whose first hospital visit resulted in immediate hospitalization was 22.4% in 2017. Epidemiological indicators such as prevalence, incidence, and hospitalization rate play an important role in planning social and financial resource allocation. Therefore, efforts to produce more accurate epidemiological indicators are very important and this study's findings could have a significant social impact.

OBJECTIVES: There is a paucity of available research to guide clinical practice in delusional disorder (DD), particularly in late life. This study aimed to evaluate antipsychotic use and treatment outcomes in patients with DD aged 65 years and older. Secondarily, we sought to examine associated clinical features and socio-demographic variables. DESIGN AND SETTING: This descriptive study reviewed all consecutive cases of DD referred to an Australian old age psychiatry service over a 12-year period. Fifty-five patients were assessed in the inpatient and/or community setting, with data verified from a review of all individual medical records. MEASUREMENTS: Data were collected with respect to antipsychotic use, outcomes, and clinical features. Socio-demographic variables of DD cases were compared to a non-matched comparison group (n=278) and an age and gender matched comparison group with a 1:1 ratio (n=55). RESULTS: The predominant type of DD was persecutory (87%). Non-prominent hallucinations were experienced by 18%, and depressive symptoms occurred in 22%. There was a statistically significant association between having DD and social isolation (χ2= 11.04 (DF=1) p<0.001; McNemar's test p<0.001). Atypical antipsychotic medication was prescribed in 32 cases, with follow-up permitted in 51 of the 55 cases (mean duration 36.6 months). Sustained recovery occurred in 20%, and improvement in an additional 35% of the study sample. Four patients subsequently developed dementia, and two developed mild cognitive impairment. CONCLUSIONS: Clinical improvement, including sustained recovery, occurred in more than half of those with late life DD. The majority of those who improved (96%) received atypical antipsychotics.

Most studies on predictors of vocational outcomes are cross-sectional and results are varied. This study aimed to examine the vocational rates of patients with first-episode psychosis (FEP), identify factors predicting a lack of engagement in age-appropriate roles, and evaluate the predictive ability of a model with baseline sociodemographic information and 2-year symptom and functioning trajectories on vocational outcomes. The Singapore Early Psychosis Intervention Program (EPIP) has maintained a standing database on patient clinico-demographic information. The primary outcome, vocational status, was operationalized as "meaningfully employed", that is, being gainfully employed or engaged in an age-appropriate role, and "unemployed". Using logistic regression, the predictive ability of the proposed model was evaluated. Vocational data was available for 1177 patients accepted into EPIP between 2001 and 2012. At the end of two years in the service, 829 (70.4%) patients were meaningfully employed and 348 (29.6%) patients were unemployed. The binary logistic regression model on the prediction of 2-year vocational outcomes yielded an AUC of 0.759 (SEâ¯=â¯0.016, p-valueâ¯<â¯0.001). Clinico-demographic risk factors for being unemployed at the end of two years included being Malay, single, and unemployed at baseline; having a longer duration of untreated psychosis (DUP); a diagnosis of schizophrenia, schizophreniform, or delusional disorder at baseline; and belonging to the 'delayed response' or 'slower response and no response' general psychopathology trajectories. We have proposed a model that allows vocational outcomes to be predicted with high specificity. The results of this study will be relevant in developing future intervention models to improve outcomes among FEP patients with different illness trajectories.

BACKGROUND: Tardive dyskinesia (TD) is a movement disorder resulting from treatment with typical and atypical antipsychotics. An estimated 16-50% of patients treated with antipsychotics have TD, but this number may be underestimated. The objectives of this study were to build an algorithm for use in electronic health records (EHRs) for the detection and characterization of TD patients, and to estimate the prevalence of TD in a population of patients exposed to antipsychotic medications. METHODS: This retrospective observational study included patients identified in the Optum EHR Database who received a new or refill prescription for an antipsychotic medication between January 2011 and December 2015 (follow-up through June 2016). TD mentions were identified in the natural language-processed clinical notes, and an algorithm was built to classify the likelihood that the mention represented documentation of a TD diagnosis as probable, possible, unlikely, or negative. The final TD population comprised a subgroup identified using this algorithm, with ≥1 probable TD mention (highly likely TD). RESULTS: 164,417 patients were identified for the antipsychotic population, with1,314 comprising the final TD population. Conservatively, the estimated average annual prevalence of TD in patients receiving antipsychotics was 0.8% of the antipsychotic user population. The average annual prevalence may be as high as 1.9% per antipsychotic user per year, allowing for a more-inclusive algorithm using both probable and possible TD. Most TD patients were prescribed atypical antipsychotics (1049/1314, 79.8%). Schizophrenia (601/1314, 45.7%), and paranoid and schizophrenia-like disorders (277/1314, 21.1%) were more prevalent in the TD population compared with the entire antipsychotic drug cohort (13,308/164,417; 8.1% and 19,359/164,417; 11.8%, respectively). CONCLUSIONS: Despite a lower TD prevalence than previously estimated and the predominant use of atypical antipsychotics, identified TD patients appear to have a substantial comorbidity burden that requires special treatment and management consideration.

BACKGROUND: Currently, all of the studies that focus on the relationship between paranoia and criminal offenses exclusively concern subjects suffering from a delusional paranoid disorder. However, subjects with single paranoid personality disorder, without any associated delusional disorder, are not uncommon in forensic practice. OBJECTIVES: This study aims to describe the offenses committed by subjects suffering from a single paranoid personality disorder and to compare them with the offenses committed by the subjects affected by a paranoid delusional disorder associated with paranoid personality disorder. Our initial hypothesis is that both populations have a comparable criminological profile. METHODS: Based on a 17 year-long experience carried out in the framework of a forensic assessment, we have selected all subjects presenting a paranoid personality disorder, whether single or associated with paranoid delusional disorder. The selected individuals were divided into two groups according to whether they presented paranoid delusional disorder or not. The offenses were grouped into criminal categories. The alpha risk was fixed at 1%. Data analysis is done by SAS software version 9.4. RESULTS: In a sample of 106 subjects presenting a paranoid personality disorder, including 4 women and 102 men, we found 79 subjects with a single paranoid personality and 27 with an associated paranoid delusional disorder. The average age at the time of the offense was 41 for those with single personality disorders and 49 for those with paranoid delusional disorders. Both groups had forensic antecedents (41%, 11/27 of paranoid delusional disorder and 51%, 40/79 of single paranoid personality disorder). Psychiatric history was more frequent in the paranoid delusional disorder group (59%, 16/27) than in the single paranoid personality disorder group (13%, 10/79). History of addiction was comparable in terms of alcohol abuse (26% in both groups) and other substances (7.5%, 2/27 of paranoid delusional disorder and 9%, 7/79 of single paranoid personality disorder). Comparison of the two groups highlighted significant differences in the type of criminal offenses committed (Fisher's exact test: P=0.0003, alpha risk <0.0001). The offenses committed by delusional authors essentially came down to verbal or physical violence, including homicide (44%, 12/27), and were usually focused on a designated persecutor. Sexual violence was rare. On the other hand, paranoid personality disorder was associated with a wider variety of offenses. Sexual offenses (including 28 rapes, 35%, 28/79) were thus almost as frequent as murder, and attempted murder (38%, 30/79). This diversity of committed offenses was found in their forensic antecedents. In these subjects, the logic of omnipotence may had over ruled the logic of revenge. CONCLUSION: We conducted a retrospective study on 106 subjects with paranoid personality disorder, including 27 subjects with associated paranoid delusional disorder. The comparison of the two groups demonstrated significant differences in offenses. Verbal and physical but non-sexual violence, committed in a delusional logic, was found among delusional subjects, while the forms of violence were more multiform in the single paranoid personality disorder group, frequently including sexual violence. This is, as far as we know, the first study describing the medico-legal acting-out of paranoid personalities. These results, which will need to be confirmed by future studies, point out the importance of the criminological risk that may be associated with paranoid personality disorder, without any associated delusional disorder.

INTRODUCCÖN/ANTECEDENTES: La conducta suicida en el trastorno delirante (TD) ha sido escasamente estudiada. OBJETIVO: Profundizar en el conocimiento de las características demográficas, ambientales, psicosociales y clínicas del suicido en un grupo de pacientes con TD con la finalidad de contribuir a generar y sugerir estrategias que contribuyan a realizar nuevos estudios de mayor nivel explicativo. MÉTODO: Estudio epidemiológico descriptivo retrospectivo de Registro de Casos en el Dispensario de Psiquiatría e Higiene Mental de Córdoba sobre pacientes con TD según criterios DSM-IV-TR. Aquellos pacientes que cumplieron con los criterios de inclusión definidos constituyeron nuestra muestra final de 261 casos, de ellos 26 casos presentaron evidencias de intento de suicidio. Las variables sobre las que se recogió información en base a protocolos, fueron agrupadas con el orden siguiente: I. Sociodemográficos y generales. II. Factores de riesgo del TD (familiares y personales). III. Cuadro Clínico y el Diagnóstico del TD (Presentación, Sintomatología, Funcionalidad y Discapacidad, utilización de los recursos sanitarios, tratamiento, problemas psicosociales, evolución y curso) y medios letales utilizados. RESULTADOS: La edad media de los pacientes fue de 47 años y el 60% fueron hombres. Los datos sociodemográficos muestran que los pacientes con intento de suicidio residían en núcleos rurales (46,2%), no tenían estudios en un 15,4%, un 57,7% no trabajaba y un 26,9% recibía una pensión por enfermedad o jubilación laboral. El subtipo persecutorio con 8 casos, fue el más frecuente, seguido de los subtipos de grandiosidad (6 casos) y celotípico (6 casos), mixto (3 casos), erotomaníaco (2 casos) y somático (1 caso).DISCUSIÓN Y CONCLUSIÓN: Son necesarios futuros estudios prospectivos para investigar los factores de protección, de riesgo y/o asociados al suicidio en el TD.
Introduction / background: Suicidal behavior in delusional disorder (DD) patients has been poorly studied. Objective: Investigate the demographic, environmental, psychosocial and clinical characteristics of the suicidal behavior in a group of patients with DD. Method: Retrospective descriptive study of DD cases registered at Psychiatry and Mental Hygiene Clinic of Cordoba according to DSM-IV criteria was conducted. We obtained a sample of 261 DD patients who met the inclusion criteria, of them 26 cases presented evidence of suicidal behavior. Data and variables collected were divided into 4 groups: I. Socio-demographic and general data. II. DD risk factors (personal and family). III. DD clinical picture and diagnosis (presentation, symptoms, disability, use of health care resources, treatment, and evolution) and lethal methods used. Results: The mean age of the patients was 47 years old and 60% were males. Socio-demographic data show that 46.2% of patients with suicidal behavior lived in rural areas, only 15,4% were analphabet, 57,7% were unemployed, and 26.9% were receiving a pension because of illness or retirement. The persecutory subtype with 8 cases was the most frequent presentation, followed by grandiose (6 cases) and jealous (6 cases), mixed (3 cases), erotomanic (2 cases) and somatic (1 case) subtypes. Discussion and conclusion: It is necessary to conduct future prospective studies to investigate the protective and risks factors associated with the suicidal behavior in DD patients.

RESUMEN La esquizofrenia es una de las enfermedades más invalidantes de los seres humanos, conocida como el «cáncer de la psiquiatría¼. Se impone como un gran reto social debido a su incidencia, su potencial en cronicidad y severidad así como las consecuencias que implica para la familia y la sociedad en general. La alta prevalencia de la enfermedad, de 1/100 habitantes, independientemente de las características sociales o económicas de los diferentes países, hace de esta un factor de gran impacto por su gran repercusión humana, económica y social, pues afecta al ser humano en la etapa más productiva de la vida. En el 75 % de los casos los primeros síntomas de la enfermedad aparecen entre los 16 y 25 años de edad. Por el grado de incapacidad que produce se afectan los estudios, la vida social y laboral. En este trabajo, se muestra a través del estudio de un caso ingresado en el Hospital Psiquiátrico Antonio Guiteras Holmes, de Matanzas, las principales afectaciones de esta enfermedad en las esferas afectiva, cognitiva y conductual (AU).
ABSTRACT The schizophrenia is one of the most invaliding diseases of the human beings, known as the cancer of Psychiatrics. It is a great social challenge due to its incidence, its potential in chronicity and severity, and also the consequences it implies for the family and society in general. The high prevalence of this disease, 1/100 inhabitants, regardless of the social and economic characteristics of the different countries, makes it a factor of great impact owing its social, economic and human repercussion because it affects the human being during the most productive stage of his life. In 75 % of the cases, the first diseases symptoms appear between the ages of 16 and 25 years. Because of the disability level it produces, the social and professional life and the studies are affected. In this work, through the study of a case admitted in the Psychiatric Hospital Antonio Guiteras Holmes, of Matanzas, the main burdens of this disease in the affective, cognitive and behavioural spheres are shown (AU).

The elevated cardiovascular risk of patients with schizophrenia contributes to a reduced life expectancy of 15-20years. This study investigated whether cardiac autonomic dysfunction (CADF) in schizophrenia is related to chronotropic incompetence, an established cardiovascular risk marker. We investigated thirty-two patients suffering from paranoid schizophrenia and thirty-two control subjects matched for age, sex, body mass index and fat free mass. A cardiopulmonary exercise test (CPET) was performed to study heart rate responses to exercise as well as submaximal (ventilatory threshold 1, VT1) and maximal endurance capacities (peak oxygen consumption, VO2peak; peak power output, Ppeak). In addition, epinephrine and norepinephrine levels were assessed in a subset of patients. Fitness parameters were significantly reduced in all patients. Most investigated physiological parameters were significantly different at rest as well as during peak exercise being in line with previously described CADF in schizophrenia. In particular, 14 out of 32 patients were classified as chronotropically incompetent whereas no control subject was below the cut-off value. In addition, a positive correlation of a slope reflecting chronotropic incompetence with peak oxygen uptake (p<0.001) was observed in patients only indicating a close correlation to the lack of physical fitness. The catecholamine increase was reduced in patients after exercise. This study identified a novel cardiac risk factor in patients with schizophrenia. Moreover, it seems to be associated with reduced physical fitness and indicates targets for exercise intervention studies. Future studies are warranted to elucidate pathophysiological mechanisms of this cardiac condition.

OBJECTIVES: Delusional misidentification syndromes (DMS) correspond to the delusional belief of misidentification of familiar persons, places or objects and to the conviction that they have been replaced or transformed. Several cases of patients who developed violent behavior while suffering from DMS have been published. This led some authors to consider patients with DMS at risk of violence. However, only a few studies have focused on the potential relationship between violence and DMS. The aim of our study was to explore this relationship with a literature review of published cases of patients having committed violent acts associated to DMS. METHODS: A systematic literature search was conducted on PubMed up to January 2017 using the following term combination "misidentification" and "violence" Fifteen cases of patients with DMS who had committed violent acts were identified. The data from these descriptions were analyzed and synthetized. RESULTS: Most of the patients were men with a diagnosis of schizophrenia and Capgras syndrome. Acts of violence were severe with a relatively high number of murders or attempted murders. For half of the patients these violent acts were perpetrated with weapons. Victims were regularly the patient's family members and the assaults were usually not planned. Delusional syndromes often progressed for several years. Importantly, substance abuse, which is known to increase the risk of violence in patients with schizophrenia, was only observed in two patients. CONCLUSION: DMS are associated with several risk factors of violence, such as a diagnosis of schizophrenia, specific delusions including megalomania, persecution, negative affects and identified targets. Despite this risk for severe violence, there are no existing guidelines on how to assess and treat DMS in schizophrenia. Accordingly, we propose (1) the establishment of formal diagnostic criteria, (2) the development of rigorous research on these syndromes and (3) the integration of DMS in assessment of violence risk in schizophrenic patients.

OBJECTIVE: The aim of this study was to analyze the possible reasons for acute admission to a department for geriatric psychiatry. The reasons for hospitalization, the psychiatric and somatic comorbidities of the patients over 65 years old with schizophrenia, schizoaffective disorder and delusional disorder were examined to identify patterns and risk profiles. MATERIAL AND METHODS: A retrospective analysis was carried out using paper and electronic patient records of a department of acute care for geriatric psychiatry and psychotherapy. During the assessment period 206 successive patients over 65 years old were included in the study. The patient cohort included 64 patients with schizophrenia according to the international classification of diseases 10 (ICD-10, category F20), 78 patients with persistent delusional disorder (ICD-10, F22) and 64 patients with schizoaffective disorder (ICD-10, F25). RESULTS: The reason for admission for one third of the patients in all three groups was aggressive behavior, whereas delusions and hallucinations were more frequent in the groups of F20 and F22 patients than in patients with schizoaffective disorders (F25). Somatic comorbidities were seen significantly more often in the group of F22 patients than in the other two groups. CONCLUSION: Acute admission was essentially due to acute psychiatric symptoms. Additional somatic comorbidities and psychosocial influencing factors played only a minor role in this study. The patients examined in this study constituted a special group within the acute treatment of inpatient psychiatry because they showed distinctive psychopathological productive symptoms but were relatively healthy from a somatic point of view. Patients with the diagnosis of schizophrenia (F20) or schizoaffective disorder (F25) were significantly different from patients classified into the group of delusional disorders (F22).

AIM: Retrospective studies of first-episode psychosis patients have reported that psychosis often remains untreated for some time. Yet, from clinical samples, the characteristics and number of non-diagnosed untreated psychosis patients in a community can only be estimated. Thus, this short report compares socio-demographic and clinical features of diagnosed and non-diagnosed psychotic individuals assessed in the community. METHODS: Using telephone interviews, we clinically assessed 2682 community participants (aged 16-40 years) in the Canton of Bern, Switzerland, to examine the characteristics of non-diagnosed psychosis. RESULTS: Of the 41 detected psychosis patients (1.5% of the sample), 21 (54%) had already been diagnosed and treated. Non-diagnosed individuals experienced a delusional disorder (DD) (n = 10) more frequently than diagnosed individuals (n = 1), but did not differ in other socio-demographic characteristics. CONCLUSION: Further study of DD should be emphasized, along with increased awareness of the condition in primary healthcare services, as individuals with DD might present themselves for other complaints.

INTRODUCTION: The experience of psychosis or related treatment can be conceptualized as a traumatic event, which might lead to posttraumatic stress disorder (PTSD) or PTSD syndrome (which is defined as the presence of PTSD symptoms irrespective of the DSM-IV criterion A definition of a traumatic event as an actual or threatened harm). Few studies explored the subject so far. METHODS: This cross-sectional study included 52 clinically stabilized patients who were hospitalized for a first-psychotic episode during the two years preceding the study. Sociodemographic and clinical information were collected including past trauma history and drug and alcohol use. Patients were administered the Clinician-Administered PTSD Scale (CAPS), the Major Depression Inventory (MDI), the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning scale (GAF), and the Brief COPE. RESULTS: A total of 22 patients (42.3%) met full PTSD criteria and 36 patients (69.2%) met PTSD syndrome criteria. Full PTSD as well as PTSD syndrome were both associated with physical restraint, higher scores on the MDI and its maladaptive coping scales. The most distressing symptoms were paranoid delusions, and the most distressing treatment experiences involved physical restraint and problems with other hospitalized patients. DISCUSSION/CONCLUSIONS: Our data showed high rates of psychosis-related PTSD. To prevent PTSD, conditions of hospitalization should be optimized and the use of coercive treatments should be limited. Subjects with recent-onset psychosis should be screened for PTSD symptoms. Improving coping abilities with a well-fitted therapy would be useful in these patients.

Approximately half of all patients presenting to dermatologists exhibit signs and symptoms of psychiatric conditions that are either primary or secondary to cutaneous disease. Because patients typically resist psychiatric consult, dermatologists often are on the front line in evaluating and treating these patients. Accordingly, distinguishing the specific underlying or resulting psychiatric condition is essential for effective treatment. The etiology, epidemiology, clinical presentation, diagnosis, and first-line treatment of specific primary psychiatric causes of dermatologic conditions, including delusional infestation, Morgellons syndrome, olfactory reference syndrome, body dysmorphic disorder, excoriation disorder, trichotillomania, and dermatitis artefacta are discussed here, followed by a discussion of the recommended treatment approach with an overview of the different first-line therapies discussed in this review, specifically cognitive behavioral therapy, atypical antipsychotics, selective serotonin reuptake inhibitors, and tricyclic antidepressants. Included is a guide for dermatologists to use while prescribing these medications.

BACKGROUND: Our aim was to investigate the influence of depressive symptoms on the clinical presentation of Persistent Delusional Disorder (PDD). METHODS: We have previously conducted a retrospective review of patients diagnosed with PDD (nâ¯=â¯455). We divided this sample into two groups according to the presence or absence of co-morbid depressive symptoms - a subsample of PDD with depressive co-morbidity (PDDâ¯+â¯D; nâ¯=â¯187) and a subsample of PDD without depressive co-morbidity (PDD only; nâ¯=â¯268). RESULTS: PDDâ¯+â¯D group had a significantly younger age at onset of PDD. The PDDâ¯+â¯D group received significantly more antidepressants but had similar response and adherence rates. CONCLUSIONS: The presence of depressive symptoms in 41% of the study population did not appear to influence the clinical presentation or response to treatment.

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. Data were gathered on sociodemographics, illness duration, Barona-Index estimation of intelligence quotient (IQ), and global functioning, along with a thorough psychopathological assessment using the Positive and Negative Syndrome Scale (PANSS). Comparisons between both groups were calculated using χ2, Student t, and multivariate analysis of covariance tests. RESULTS: Patients with DD were older (mean [SD], 50.3 [14.6] years vs. 36.6 [11.1] years; t = 8.597; P ≤ 0.0001), were more frequently married (45.4% vs. 10.8%; χ2 = 38.569; P ≤ 0.0001), and had a higher mean estimated premorbid IQ (111.4 vs. 105.4; t = 2.609; P ≤ 0.01). On the other hand, SZ patients were predominantly male (71.4% vs. 48.9%; χ2 = 14.433; P ≤ 0.0001) and had greater work-related disability than DD patients (20.5% vs. 50.3%; χ2 = 19.564; P ≤ 0.001). Overall, the DD group showed a less severe PANSS psychopathology than SZ group. Thus, total mean (SD) PANSS scores for schizophrenia and delusional disorder, respectively, were 76.2 (22.4) versus 54.1 (18.4) ( t = -8.762; P ≤ 0.0001). Moreover, patients with DD showed a better global functioning than those with SZ (62.7 [13.2] vs. 51.9 [16.9]; F = 44.114; P ≤ 0.0001). CONCLUSIONS: DD is a milder and distinct disorder compared to SZ in terms of psychopathology and global functionality.

Resumen Introducción/antecedentes: La conducta suicida en el trastorno delirante (TD) ha sido escasamente estudiada. Objetivo: Profundizar en el conocimiento de las características demográficas, ambientales, psicosociales y clínicas del suicido en un grupo de pacientes con TD con la finalidad de contribuir a generar y sugerir estrategias que contribuyan a realizar nuevos estudios de mayor nivel explicativo. Método: Estudio epidemiológico descriptivo retrospectivo de Registro de Casos en el Dispensario de Psiquiatría e Higiene Mental de Córdoba sobre pacientes con TD según criterios DSM-IV-TR. Aquellos pacientes que cumplieron con los criterios de inclusión definidos constituyeron nuestra muestra final de 261 casos, de ellos 26 casos presentaron evidencias de intento de suicidio. Las variables sobre las que se recogió información en base a protocolos, fueron agrupadas con el orden siguiente: I. Sociodemográficos y generales. II. Factores de riesgo del TD (familiares y personales). III. Cuadro Clínico y el Diagnóstico del TD (Presentación, Sintomatología, Funcionalidad y Discapacidad, utilización de los recursos sanitarios, tratamiento, problemas psicosociales, evolución y curso) y medios letales utilizados. Resultados: La edad media de los pacientes fue de 47 años y el 60% fueron hombres. Los datos sociodemográficos muestran que los pacientes con intento de suicidio residían en núcleos rurales (46,2%), no tenían estudios en un 15,4%, un 57,7% no trabajaba y un 26,9% recibía una pensión por enfermedad o jubilación laboral. El subtipo persecutorio con 8 casos, fue el más frecuente, seguido de los subtipos de grandiosidad (6 casos) y celotípico (6 casos), mixto (3 casos), erotomaniaco (2 casos) y somático (1 casos). Discusión y conclusión: Son necesarios futuros estudios prospectivos para investigar los factores de protección, de riesgo y/o asociados al suicidio en el TD.
Introduction/Background: Suicidal behavior in delusional disorder (DD) patients has been poorly studied. Objective: Investigate the demographic, environmental, psychosocial and clinical characteristics of the suicidal behavior in a group of patients with DD. Method: Retrospective descriptive study of DD cases registered at Psychiatry and Mental Hygiene Clinic of Cordoba according to DSM-IV criteria was conducted. We obtained a sample of 261 DD patients who met the inclusion criteria, of them 26 cases presented evidence of suicidal behavior. Data and variables collected were divided into 4 groups: I. Socio-demographic and general data. II. DD risk factors (personal and family). III. DD clinical picture and diagnosis (presentation, symptoms, disability, use of health care resources, treatment, and evolution) and lethal methods used. Results: The mean age of the patients was 47 years old and 60% were males. Socio-demographic data show that 46.2% of patients with suicidal behavior lived in rural areas, only 15.4% were analphabet, 57.7% were unemployed, and 26.9% were receiving a pension because of illness or retirement. The persecutory subtype with 8 cases was the most frequent presentation, followed by grandiose (6 cases) and jealous (6 cases), mixed (3 cases), erotomanic (2 cases) and somatic (1 case) subtypes. Discussion and conclusion: It is necessary to conduct future prospective studies to investigate the protective and risks factors associated with the suicidal behavior in DD patients.

Delusion is central to the conceptualization, definition, and identification of schizophrenia. However, in current classifications, the presence of delusions is neither necessary nor sufficient for the diagnosis of schizophrenia, nor is it sufficient to exclude the diagnosis of some other psychiatric conditions. Partly as a consequence of these classification rules, it is possible for delusions to exist transdiagnostically. In this article, we evaluate the extent to which this happens, and in what ways the characteristics of delusions vary according to diagnostic context. We were able to examine their presence and form in delusional disorder, affective disorder, obsessive-compulsive disorder, borderline personality disorder, and dementia, in all of which they have an appreciable presence. There is some evidence that the mechanisms of delusion formation are, at least to an extent, shared across these disorders. This transdiagnostic extension of delusions is an argument for targeting them therapeutically in their own right. However there is a dearth of research to enable the rational transdiagnostic deployment of either pharmacological or psychological treatments.
