RESUMO
ABSTRACT Recent studies suggested that cannabis use influences on the emergence of psychosis by disrupting neurodevelopmental processes that occur during adolescence and early adulthood and which are reflected on brain anatomical changes detectable with MRI. However, no MRI studies have investigated whether intrauterine neurodevelopmental abnormalities also interact with later cannabis use to influence on psychosis risk. We investigated differences between first-episode psychosis (FEP) patients with history of cannabis use (FEPC+, n=28), FEP subjects without cannabis use (FEPC-, n=78) and healthy controls (n=80) in regard to the frequency of absent or short Adhesio Interthalamica (AI), a well-established marker of intrauterine neurodevelopment. The FEPC+ subgroup had a significantly lower prevalence of absent AI than FEPC- subjects, as well as a lack of a significantly shorter AI length compared to controls (as found in FEPC- subjects). These preliminary results show that psychosis subjects with cannabis use present a low rather than high frequency of absent AI, suggesting that fixed intrauterine neurodevelopmental abnormalities may not be associated with cannabis use later in life to influence on the emergence of psychosis. This is consistent with a view that multiple different etiological processes may lead to similar clinical presentations in patients with FEP.
RESUMO
The absence of the adhesio interthalamica (AI; also called interthalamic adhesion or massa intermedia) and the presence of a large cavum septum pellucidum (CSP) later in life have been related to neurodevelopmental alterations and have not been systematically investigated in epilepsy to date. This study carried out a MRI evaluation of the AI and CSP in a large sample with mesial temporal lobe epilepsy (MTLE). A total of 179 patients, classified according to the side of the epileptogenic focus, and 156 age- and sex-balanced healthy controls were assessed. Between-group comparisons of the prevalence and length of both AI and CSP were conducted. Neuropsychological assessments were also performed in 160 MTLE patients. The patients exhibited reduction in the AI prevalence (P < 0.05; FDR-uncorrected) and length (P < 0.05; FDR-corrected) when compared to controls. Patients without AI showed lower scores in a proportion of neuropsychological tests than patients with AI. No CSP differences were found between MTLE patients and controls. These results support that AI anomalies have clinical significance in MTLE, as well as indicate that neurodevelopmental alterations may be implicated in this disorder.

Existem diversos estudos sobre preditores da não adesão, mas poucos mostram estratégias efetivas para lidar com esse problema. Uma revisão da literatura sobre desistência em psicoterapia mostrou que quase metade dos pacientes que ingressam num atendimento não o concluem. A medida na psicoterapia em geral é a de não adesão, ou desistência do tratamento; no presente trabalho serão apresentados dados relativos à adesão ao tratamento da enurese com alarme de urina. A taxa de desistência em um grupo de 61 crianças e adolescentes foi levantada considerando três condições: suas famílias não compareceram aos atendimentos, não responderam ao contato telefônico ou relataram ter abandonado os procedimentos. A desistência correspondeu a 19,6% da amostra e a idade do grupo dos desistentes era significativamente inferior, quando comparada à daqueles que aderiram ao tratamento. A já demonstrada associação entre a intolerância parental e a idade do filho explica os resultados e aponta para a necessidade de trabalho educativo intenso com os pais de adolescentes portadores de enurese.
Although there are several studies about adherence prevalence and predictors, few of them demonstrate efficient strategies to deal with this issue. A literature review found that about half of the patients that initiate psychotherapy do not conclude the process. Therefore, the measure of adherence is usually non-adherence, assessed by treatment dropout. In this paper, we present data related to dropout of alarm treatment for nocturnal enuresis. Sixty-one children and adolescents that initiated alarm treatment were included. Families missing appointments, not replying to phone calls or stating that treatment procedures were abandoned characterized dropout. Twelve families dropped out from treatment, corresponding to 19.6% of the sample. Only age was significantly related to dropout: younger children were more likely to abandon treatment. The already known relation between age and parentss intolerance explains the results and determinates the necessity of an intense informative work with parents of enuretic children.
Il existe plusieurs études sur ladhésion avec une ênfase dans la prévalence et les facteurs prédictifs de non-adhésion, mais peu de ces montre des stratégies efficaces pour faire face à ce problème. Une revue de la littérature sur l'abandon dans la psychothérapie a montré que près de la moitié des patients admis dans un soin de ne pas conclure. La mesure de la psychothérapie en général cést la non adhésion, représenté par l'abandon ou la cessation du traitement. Le document présente des données sur le traitement d'énurésie nocturne avec lalarm de urine. Nous avons mené une enquête sur les niveaux de retrait d'un groupe de 61 enfants et adolescents. Lorsque les familles n'ont pas assisté aux séances, ne répondent pas au téléphone ou auraient abandonné les procédures ont été considérés comme des décrocheurs. Le retrait est intervenu dans 12 des 61 cas, représentant 19,6% de l'échantillon. Considérant l'âge moyen des participantesverifica que ceux qui ont abandonné le traitement étaient significativement plus jeunes. L'association précédemment établie entre l'intolérance des parents et l'âge de l'enfant explique les résultats et les points à la nécessité d'un travail pédagogique intensif avec les parents d'adolescents atteints d'énurésie.
Hay diversos estudios sobre la prevalencia y predictores de la no adhesión, pero pocos muestran estrategias efectivas para hacer frente a este problema. Una revisión de la literatura sobre la deserción en la psicoterapia mostró que casi la mitad de los pacientes que ingresan en la atención no la concluyen. La medida en la psicoterapia en general es la de no adhesión, representada por el abandono o deserción del tratamiento. En este trabajo serán presentados datos relativos a la deserción al tratamiento de la enuresis través de la alarma de orina. Fue realizada una investigación sobre los niveles de la deserción de un grupo de 61 niños y adolescentes. Cuando las familias no comparecerán a las sesiones, no contestarán al telefono, o relatabán tener abandonado los procedimientos, fueron considerados desertores. La deserción ocurrió en 12 de 61 casos, lo que representa 19,6% de la muestra. La asociación ya establecida entre la intolerancia de los padres y la edad del niño explica los resultados y señala la necesidad de una intensa labor educativa con los padres de los adolescentes con enuresis.
