Faktorenanalytische Untersuchung und Rehabilitätsbestimmung der statischen und dynamischen Pupillometrie bei Normalpersonen und psychopathologischen Gruppen [Factor analytic study and determination of rehabilitation of static and dynamic pupillometry in normal persons and psychopathologic groups]

Variables measured during static and dynamic pupillometry were factor-analyzed. Following factors were obtained regardless whether investigations were carried out in normals or in psychiatric patients: A static factor, a dynamic factor, a stimulus-specific factor and a restitution-dependent factor. Evaluation of reliability in normals demonstrated a high reliability for the static variables of pupillometry.

Auditory verbal hallucinations of epileptic origin.

Complex auditory hallucinations are often characterized by hearing voices and are then called auditory verbal hallucinations (AVHs). While AVHs have been extensively investigated in psychiatric patients suffering from schizophrenia, reports from neurological patients are rare and, in most cases, incomplete. Here, we characterize AVHs in 9 patients suffering from pharmacoresistant epilepsy by analyzing the phenomenology of AVHs and patients' neuropsychological and lesion profiles. From a cohort of 352 consecutively examined patients with epilepsy, 9 patients suffering AVHs were identified and studied by means of a semistructured interview, neuropsychological tests, and multimodal imaging, relying on a combination of functional and structural neuroimaging data and surface and intracranial EEG. We found that AVHs in patients with epilepsy were associated with prevalent language deficits and damage to posterior language areas and basal language areas in the left temporal cortex. Auditory verbal hallucinations, most of the times, consisted in hearing a single voice of the same gender and language as the patient and had specific spatial features, being, most of the times, perceived in the external space, contralateral to the lesion. We argue that the consistent location of AVHs in the contralesional external space, the prominence of associated language deficits, and the prevalence of lesions to the posterior temporal language areas characterize AVHs of neurological origin, distinguishing them from those of psychiatric origin.

Construction of a scale to evaluate the diurnal impact of insomnia

The objective of this study was to develop and validate a scale to assess the diurnal impact of insomnia. The Insomnia Diurnal Impact Scale (IDIS) comprises six items designed to evaluate the daytime effects of insomnia. The sychometric properties of the original scale were analysed in a sample of 172 students, while its ability to differentiate insomniacs and non-insomniacs (according to the International Classification of Diseases (ICD)-10 criteria) was examined in a sample of 79 psychiatric patients and 82 individuals from the community. The psychometric properties of the English version were then analysed in a sample of 44 Englishspeaking participants. The results showed the internal consistency coefficient to be very good (0.86), with testretest reliability at 1 month being 0.79. A single factor explained almost 60% of the variance. Correlation of the IDIS with other scales varied between moderate and high values. Sensitivity was 78% and specificity 57% in the community sample, while the corresponding figures for the psychiatric population were 83% and 63%. Cronbach's ¿ coefficient for the English version reached a value of 0.93. These results indicate that the IDIS shows adequate reliability and validity with both general and psychiatric populations, and also that it can discriminate between the presence and absence of insomnia. The English version presents good preliminary results regarding item-corrected total correlation and internal consistency. In conclusion, the IDIS appears to be a useful tool in the primary care and mental health contexts for assessing insomnia-related diurnal dysfunction.

A comparison of the dental status and treatment needs of older adults with and without chronic mental illness in Sevilla, Spain

Objectives: To study the dental status and treatment needs of institutionalized older adults with chronic mental illness compared to a non-psychiatric control sample. Study Design: The sample size was 100, in which 50 were psychogeriatric patients (study group; SG) classified according to DSM-IV, with a mean age of 69.6 ± 6.7 years, and 50 non-psychiatric patients (control group; CG), with a mean age of 68.3 ± 6.9 years. Clinical oral health examinations were conducted and caries were recorded clinically using the Decayed, Missing and Filled Teeth Index (DMFT). Results were analyzed statistically using the Student"s t-test or analysis of variance. Results: Caries prevalence was 58% and 62% in SG and CG, respectively. DMFT index was 28.3 ± 6.6 in SG and 21.4 ± 6.07 in CG (p < 0.01). Mean number of decayed teeth was higher in SG (3.1) compared to CG (1.8) (p=0.047). Mean number of missing teeth were 25.2 and 16.4 in SG and CG respectively (p<0.05). DMFT scores were higher in SG in all the age groups (p < 0.01). Mean number of teeth per person needing treatment was 3.4 in SG and 1.9 in CG (p= 0.037). The need for restorative dental care was significantly lower in the SG (0.8 teeth per person) than in the CG (1.7 teeth per person) (p = 0.043). Conclusions: Institutionalized psychiatric patients have significantly worse dental status and more dental treatment needs than non-psychiatric patients.

Diagnostic interview for genetic studies (DIGS): inter-rater and test-retest reliability of alcohol and drug diagnoses

The semi-structured diagnostic interview for genetic studies (DIGS) was developed to assess major mood and psychotic disorders and their spectrum manifestations in genetic studies. Our research group developed a French version of the DIGS and tested its inter-rater and test-retest reliability in psychiatric patients. In this article, we present estimates of the reliability of substance use and antisocial personality disorders. High kappa coefficients for inter-rater reliability were found for drug and alcohol as well as antisocial personality diagnoses and slightly lower kappas for test-retest reliability. Combined with evidence of the reliability of major mood and psychotic disorders, these findings support the suitability of the DIGS for studies of familial aggregation and comorbidity of psychiatric disorders including substance use and antisocial personality disorders.

Age and adverse drug reactions from psychopharmacological treatment: data from the AMSP drug surveillance programme in Switzerland.

QUESTION UNDER STUDY: The frequency of severe adverse drug reactions (ADRs) from psychotropic drugs was investigated in hospitalised psychiatric patients in relation to their age. Specifically, the incidence of ADRs in patients up to 60 years was compared to that of patients older than 60 years. METHODS: Prescription rates of psychotropic drugs and reports of severe ADRs were collected in psychiatric hospitals in Switzerland between 2001 and 2010. The data stem from the drug surveillance programme AMSP. RESULTS: A total of 699 patients exhibited severe ADRs: 517 out of 28,282 patients up to 60 years (1.8%); 182 out of 11,446 elderly patients (1.6%, ns). Logistic regression analyses showed a significantly negative relationship between the incidence of ADRs and patients' age in general and in particular for weight gain, extrapyramidal motor system (EPMS) symptoms, increased liver enzymes and galactorrhoea. A significantly negative relationship was observed for age and the dosages of olanzapine, quetiapine, risperidone, valproic acid and lamotrigine. When comparing age groups, frequency of ADRs was lower in general for antipsychotic drugs and anticonvulsants, in particular for valproic acid in the elderly. Weight gain was found to be lower in the elderly for antipsychotic drugs, in particular for olanzapine. For the group of mood-stabilising anticonvulsants (carbamazepine, lamotrigine and valproic acid) the elderly exhibited a lower incidence of reported allergic skin reactions. CONCLUSION: The results suggest that for psychiatric inpatients the incidence of common severe ADRs (e.g., weight gain or EPMS symptoms) arising from psychotropic medication decreases with the age of patients.

Risques et bénéfices d'une approche interventionnelle face aux corps étrangers digestifs [Digestive foreign body management].

Foreign body (FB) ingestion is a frequent reason for gastroenterology consulting. Eighty percent of these ingestions are accidental and observed among paediatric subjects. However, intentional repetitive ingestions are also observed, especially amongst prisoners or psychiatric patients. Most FBs pass throughout the digestive tract without any complication and without any need for surgical or endoscopic intervention. Nevertheless, around 10-20% of cases require an endoscopy examination and 1% will lead to a surgical intervention. Management approaches should favor inter-disciplinarity, balance benefits and risks of FB removal based on its location, and integrate psychiatric comorbidities into the decision process.

Det vårdande samtalet

Syftet med studien är att utgående från ett vårdvetenskapligt perspektiv utveckla en teori för det vårdande samtalet, speciellt som det gestaltar sig i den psykiatriska vårdkontexten. Avsikten är primärt att tillföra den kliniska vårdvetenskapen kunskaper om hur samtal mellan vårdare och patienter kan lindra lidande. Studien tar sin utgångspunkt i ett vårdvetenskapligt perspektiv som har sina rötter i Katie Erikssons caritativa vårdteori. Den metodologiska ansatsen är hermeneutisk. Forskningen har genomförts i form av fem delstudier som publicerats i internationella vetenskapliga tidskrifter. Metoderna som använts är: 1) en fenomenologisk hermeneutisk ansats för att beskriva det vårdande samtalet som det skildras av sjuksköterskor och patienter i intervjuer, 2) kvalitativ forskningssyntes av studier rörande begreppen närvaro, beröring och lyssnande, 3) kvalitativ forskningssyntes av studier rörande begreppen narrativer, berättelser, mening och förståelse, 4) en hermeneutisk ansats inspirerad av Paul Ricoeurs hermeneutik för att undersöka hur psykiatriska patienter i samtal med vårdare berättar om lidande, 5) en hermeneutisk analys av de etiska fundamenten för ett vårdande samtal i ljuset av Paul Ricoeurs etik. Resultaten från de fem delstudierna formar utgångspunkten för en teori för hur ett vårdande samtal kan tolkas. Teorin består av tre aspekter, den relationella, den narrativa, och den etiska, vilka undersökts i delstudierna. I den relationella aspekten kan vårdaren genom att lyssna, beröra och vara med-varande skapa en närvaro. Genom vårdarens gåva av sin närvaro, d v s att vara tillgänglig och till förfogande med hela sitt väsen, visas möjligheten till ett möte med patienten utan roller och inlärda repliker. När patienten kan besvara denna gåva med en inbjudan att dela något av sin värld, skapas en förbindelse i vilken patienten kan dela sitt lidande och sin värld med vårdaren. Den narrativa aspekten gestaltas i samtalet som patientens berättelse om sitt lidande. Lidandeberättelsen tar sin början i den fasad som patienten skyddar sig mot lidande och skam med. Frågan om varför patienten lider banar vägen både för en ny förståelse av fasaden och också för upplevelsen av en vändpunkt när fasadens skydd överges, vilket leder till en upplevelse av mening-i-lidandet. Artikuleringen av berättelsens poäng, mening-med-lidandet innebär dels en ny tolkning och förståelse för de förhållanden som rådde vid berättelsens början, dels de nya preferenser för hur patienten vill leva sitt liv som vuxit fram. Den etiska aspekten gestaltas i en relation som på grund av patientens lidande och vårdarens medlidande är asymmetrisk, men omfattar en ömsesidig respekt. Genom caritas skapar vårdaren ett utrymme där patienten kan (åter)upprätta sin självaktning, autonomi och sitt ansvar och därmed skapa möjligheter för ett gott liv.

Effects of sodium valproate and carbamazepine on food competition aggression in pigeons

Valproate and carbamazepine (CAR) have been proposed as adjunct alternatives for the control of aggression in psychiatric patients, although no definite conclusions have been reached. We examined the effects of these drugs on food competition offensive aggression and other behaviors in high- and low-aggression food-restricted pigeons. These were divided into pairs containing previously ranked high-aggression (N = 10 pairs) and low-aggression females (N = 10 pairs). In Experiment 1, a pigeon in each pair of high- and low-aggression subjects was treated daily with an oral dose of sodium valproate (50 mg kg-1 mL saline-1) for 15 days. The other animal received the vehicle. On days 1, 7, and 15, food competition trials (10 min) were performed 60 min after treatment. In Experiment 2, one pigeon in each pair was treated daily with an oral dose of CAR (20 mg kg-1 mL saline-1) for 15 days. Each pair was submitted to a food competition trial on days 1, 7, and 15 of treatment. Valproate (15 days of treatment) selectively decreased the time spent in offensive aggression (control: 102.7 ± 9.3 vs valproate: 32.7 ± 9.2 s; P < 0.001, ANOVA-2-TAU) of high-aggression pigeons. This was also the case for 7 and 15 days of CAR treatment (control: 131.5 ± 8.9 vs CAR: 60.4 ± 5.3, P < 0.01, and control: 122.7 ± 7.1 vs CAR: 39.1 ± 5.2; P < 0.001, ANOVA-2-TAU, respectively). Thus, the two anticonvulsive drugs have a similar effect on food competition aggression in pigeons.

Análisis del gen adra2a receptor alfa 2a adrenergico en pacientes con trastorno de hiperactividad y déficit de atención

El trastorno de hiperactividad y déficit de atención (THDA), es definido clínicamente como una alteración en el comportamiento, caracterizada por inatención, hiperactividad e impulsividad. Estos aspectos son clasificados en tres subtipos, que son: Inatento, hiperactivo impulsivo y mixto. Clínicamente se describe un espectro amplio que incluye desordenes académicos, trastornos de aprendizaje, déficit cognitivo, trastornos de conducta, personalidad antisocial, pobres relaciones interpersonales y aumento de la ansiedad, que pueden continuar hasta la adultez. A nivel global se ha estimado una prevalencia entre el 1% y el 22%, con amplias variaciones, dadas por la edad, procedencia y características sociales. En Colombia, se han realizado estudios en Bogotá y Antioquia, que han permitido establecer una prevalencia del 5% y 15%, respectivamente. La causa específica no ha sido totalmente esclarecida, sin embargo se ha calculado una heredabilidad cercana al 80% en algunas poblaciones, demostrando el papel fundamental de la genética en la etiología de la enfermedad. Los factores genéticos involucrados se relacionan con cambios neuroquímicos de los sistemas dopaminérgicos, serotoninérgicos y noradrenérgicos, particularmente en los sistemas frontales subcorticales, corteza cerebral prefrontal, en las regiones ventral, medial, dorsolateral y la porción anterior del cíngulo. Basados en los datos de estudios previos que sugieren una herencia poligénica multifactorial, se han realizado esfuerzos continuos en la búsqueda de genes candidatos, a través de diferentes estrategias. Particularmente los receptores Alfa 2 adrenérgicos, se encuentran en la corteza cerebral, cumpliendo funciones de asociación, memoria y es el sitio de acción de fármacos utilizados comúnmente en el tratamiento de este trastorno, siendo esta la principal evidencia de la asociación de este receptor con el desarrollo del THDA. Hasta la fecha se han descrito más de 80 polimorfismos en el gen (ADRA2A), algunos de los cuales se han asociado con la entidad. Sin embargo, los resultados son controversiales y varían según la metodología diagnóstica empleada y la población estudiada, antecedentes y comorbilidades. Este trabajo pretende establecer si las variaciones en la secuencia codificante del gen ADRA2A, podrían relacionarse con el fenotipo del Trastorno de Hiperactividad y el Déficit de Atención.

Anger, preoccupied attachment and domain disorganisation in borderline personality disorder

Emotional dysregulation and attachment insecurity have been reported in borderline personality disorder (BPD). Domain disorganization, evidenced in poor regulation of emotions and behaviors in relation to the demands of different social domains, may be a distinguishing feature of BPD. Understanding the interplay between these factors may be critical for identifying interacting processes in BPD and potential subtypes of BPD. Therefore, we examined the joint and interactive effects of anger, preoccupied attachment, and domain disorganization on BPD traits in a clinical sample of 128 psychiatric patients. The results suggest that these factors contribute to BPD both independently and in interaction, even when controlling for other personality disorder traits and Axis I symptoms. In regression analyses, the interaction between anger and domain disorganization predicted BPD traits. In recursive partitioning analyses, two possible paths to BPD were identified: high anger combined with high domain disorganization and low anger combined with preoccupied attachment. These results may suggest possible subtypes of BPD or possible mechanisms by which BPD traits are established and maintained.

Percepção de coerção em pacientes psiquiátricos, cirúrgicos e clínicos hospitalizados

Duzentos e cinco pacientes hospitalizados em um grande hospital universitário foram avaliados, em estudo transversal, para a identificação de sentimentos de coerção no momento da hospitalização. A amostra compunha-se de 64 pacientes psiquiátricos, 58 pacientes cirúrgicos e 83 pacientes clínicos, tanto involuntários, quanto voluntários. A voluntariedade dos pacientes psiquiátricos foi determinada por seu status legal e, a dos cirúrgicos e clínicos, pelo caráter eletivo ou emergencial da hospitalização. Os pacientes psiquiátricos eram mais jovens, apresentavam nível educacional mais elevado e escores superiores na escala SRQ em relação aos pacientes cirúrgicos e clínicos. Esses grupos não diferiam entre si no que se refere aos escores em MMSE. O Admission Experience Survey: Short Form e as escalas utilizadas durante o MacArthur Coercion Study, foram aplicados a todos os pacientes. Os resultados indicam que os pacientes psiquiátricos, tanto involuntários quanto voluntários, apresentam significativamente maior percepção de coerção do que os demais. Os pacientes cirúrgicos e clínicos não diferem entre si, entretanto referem haver sofrido também algum nível de coerção, fato que poderia merecer uma atenção maior de bioeticistas e juristas. A análise de regressão logística indica que as variáveis associadas a hospitalização involuntária são Perceived Coercion Scale, estado cognitivo e escolaridade, todas com coeficiente de correlação positivo.

Entre malucos e milicos: etnografia estereótipos familiares e papel da mulher nas relações de cuidado

Com base em etnografias desenvolvidas com pacientes psiquiátricos e com oficiais do exército, este artigo discute representações sociais sobre família, a partir de um enfoque epistemológico. Neste contexto, as discussões sobre métodos e técnicas de pesquisa etnográfica e sobre papeis sociais assumidos por mulheres nas relações familiares, ganham destaque.

Transtorno mental: dificuldades enfrentadas pela família

Utilizando uma metodologia qualitativa (entrevistas abertas, desenho-estória e análise temática) identificamos e analisamos 4 categorias (descompasso temporal, culpa, conflitos e perdas) presentes no discurso de mães (e uma irmã) de pacientes psiquiátricos do Núcleo de Atenção Psicossocial (NAPS) de Ribeirão Preto/SP, e avaliamos sua importância conforme o objetivo de se entender a dinâmica da relação entre serviço de saúde mental, paciente psiquiátrico e sua família.

Hospital-dia: para quem e para quê?

OBJETIVO: Estudar prospectivamente a população internada em um hospital-dia (HD) em relação a fatores que poderiam influenciar na melhora e na duração da internação. MÉTODOS: Foram entrevistados, para obtenção de dados sociodemográficos e avaliação da evolução, 34 pacientes internados no Hospital-Dia da Faculdade de Medicina de Botucatu, Unesp, durante um ano. O diagnóstico psiquiátrico foi avaliado pela CIDI (Composite International Diagnostic Interview), a sintomatologia psiquiátrica pela BPRS (Brief Psychiatric Rating Scale) e a incapacitação psicossocial pela DAS (Psychiatric Disability Assessment Schedule). Todos os pacientes foram acompanhados, e seus familiares, entrevistados. RESULTADOS: Predominaram mulheres (76%), jovens (61,8%), sem vínculo conjugal (71%), sem trabalho (82,4%), com diagnóstico de transtornos afetivos (44,1%) e com internações psiquiátricas prévias (44%). Apenas quatro (12%) pacientes apresentavam uma síndrome maior segundo BPRS. Houve considerável incapacitação psicossocial dos pacientes em alguns papéis sociais. Maior renda per capita foi um fator associado à melhor evolução. As internações duraram em média 74 dias. Pacientes com internações prévias tenderam a permanecer menos tempo no HD. CONCLUSÕES: Portadores de transtornos afetivos e quadros não-psicóticos geralmente não necessitam de internação por período integral em hospital psiquiátrico. Contudo, os pacientes deste estudo tiveram um elevado número de internações psiquiátricas prévias, provavelmente por necessitarem de um nível de atendimento além das possibilidades dos ambulatórios. Entretanto, pacientes com maior número de internações -- em tese mais graves -- tenderam a permanecer menos tempo no HD, o que suscita dúvidas quanto à sua adesão a serviços abertos, bem como aos possíveis fatores facilitadores dessa adesão. em um momento de crescimento expressivo no número de serviços de internação parcial no Brasil, como nos últimos anos, mais estudos são necessários a fim de esclarecer para quem e para quê são destinados esses serviços.
