RESUMO

Background: Depressive symptoms have been associated with cognitive impairment after stroke, and women may be specifically affected. Objective: The aim of this study was to investigate gender-specific characteristics in the relationship between changes in depression severity and changes in cognitive performance after stroke. Methods: We prospectively evaluated 73 patients without a previous history of depression in the first and fourth months after a first ischemic stroke. The severity of depressive symptoms was assessed using the 31-item version of the Hamilton Rating Scale for Depression, and executive function, attention, working memory, and verbal fluency were assessed using a neuropsychological battery. Results: We included 46 (63.0%) men and 27 (36.9%) women, with mean ages of 55.2 (SD ± 15.1) and 46.8 (SD ± 14.7) years, respectively. We found significant improvement in the digit span forward and Stroop dots from month 1 to month 4 post stroke for both men and women. Women, but not men, presented a correlation between changes in phonemic verbal fluency and changes in the 31-item version of the Hamilton Rating Scale for Depression scores. Improvement in depression was correlated with improvement in verbal fluency, and worsening in depression was correlated with worsening in verbal fluency. Conclusions: Our results suggest that women might be more vulnerable to the relationship between depressive symptoms and cognitive performance, and improvement of depression may be necessary for women's improvement in phonemic verbal fluency from the first to the fourth month after a stroke. We did not adjust the results for multiple comparisons. Thus, our findings might be considered preliminary, and confirmatory studies, also focusing on specific characteristics of women that could explain these differences, are warranted.

RESUMO

Peritraumatic dissociation has been considered an important feature for the development of post-traumatic stress disorders, but this concept remains widely unclear. To explore the peritraumatic experience, we interviewed eight victims of urban violence shortly after their traumatic events. The data collected were compared and analyzed according to the systematic set of procedures of Grounded Theory (GT). The alterations reported by participants were coded and categorized according to their perceptions of their inner and outer world, and the impressions of others involved, including the examiner's observations. The theoretical perspective for interpreting this study has parallels with Jaspers' psychopathology. Peritraumatic dissociation was conceived as a failure of synthesis among emerging stimuli from the internal and the external world, including the time-space flow structure, even when cognitive-perceptual tools remain intact. This synthesis qualifies the totality of the perceptual experience as coherent and meaningful to conscience, enabling possibilities for being/existing.

RESUMO

CONTEXTO: A depressão pós-AVC (DPAVC) possui uma prevalência elevada. Apesar disso, ela é pouco detectada e tratada. Muitos fatores de risco e repercussões negativas na recuperação dos pacientes estão associados à DPAVC. OBJETIVO: Revisar alguns aspectos da DPAVC como: qualidade de vida, prejuízos cognitivos, eixo HHA, localização do AVC e tratamento. MÉTODOS: Pesquisa dos últimos 10 anos da base de dados MedLine/PubMed usando as palavras-chave post-stroke depression, stroke, quality of life, hypercortisolism, cogntitive dysfunction e treatment. RESULTADOS: A prevalência de DPAVC é de 23 por cento a 60 por cento. Há poucos estudos sobre a incidência de DPAVC. A DPAVC está associada a pior prognóstico e evolução, agravo das disfunções cognitivas e redução da qualidade de vida. O hipercortisolismo está associado à DPAVC que ocorre tardiamente ao AVC. AVC em gânglios da base, região frontal esquerda e estruturas do circuito prefrontosubcortical está relacionado à frequência e à gravidade da DPAVC. CONCLUSÕES: É necessário melhoria na metodologia dos estudos para maior esclarecimento sobre a fisiopatologia da incidência da DPAVC. Programas objetivando o aumento das taxas de detecção dos pacientes deprimidos se fazem necessários inclusive para a redução dos impactos negativos na recuperação desses pacientes.

BACKGROUND: The prevalence of post-stroke depression (PSD) is elevated. Some risk factors and poor outcome have been associated with PSD. The treatment of PSD reduced the negative impact in patients recovery. Appart from these data the PSD has been under diagnosed and under treated. OBJECTIVE: Review some aspects such as quality of life, cognitive dysfunction, hypercortisolism, stroke localization and treatment of PSD. METHODS: MedLine/PubMed database search using the terms post-stroke depression, stroke, quality of life, hypercortisolism, cognitive dysfunction and treatment, published in MedLine in the last 10 years. RESULTS: PSD has a high rate of prevalence, from 23 percent to 60 percent. Few incidence rates are investigated. PSD is associated with poor outcome, increase of cognitive dysfunction and reduced quality of life. The hypercortisolism seems to be associated with PSD in the latter period of stroke. Stroke in the left frontal region, basal ganglia and some structures of prefrontosubcortical circuits have been related with frequency and severity of PSD. DISCUSSION: Some programs can be used to assist the medical care researcher with these patients in diagnosis and treatment of PSD. The research needs to be continued with clear methodological protocols in order to understand the physiopathology related to the incident PSD.

RESUMO

OBJECTIVE: To assess the cardiovascular features of Ullrich-Turner's syndrome using echocardiography and magnetic resonance imaging, and to correlate them with the phenotype and karyotype of the patients. The diagnostic concordance between the 2 methods was also assessed. METHODS: Fifteen patients with the syndrome were assessed by echocardiography and magnetic resonance imaging (cardiac chambers, valves, and aorta). Their ages ranged from 10 to 28 (mean of 16.7) years. The karyotype was analyzed in 11 or 25 metaphases of peripheral blood lymphocytes, or both. RESULTS: The most common phenotypic changes were short stature and spontaneous absence of puberal development (100%); 1 patient had a cardiac murmur. The karyotypes detected were as follows: 45,X (n=7), mosaics (n=5), and deletions (n=3). No echocardiographic changes were observed. In regard to magnetic resonance imaging, coarctation and dilation of the aorta were found in 1 patient, and isolated dilation of the aorta was found in 4 patients. CONCLUSION: The frequencies of coarctation and dilation of the aorta detected on magnetic resonance imaging were similar to those reported in the literature (5.5% to 20%, and 6.3% to 29%, respectively). This confirmed the adjuvant role of magnetic resonance imaging to Doppler echocardiography for diagnosing cardiovascular alterations in patients with Ullrich-Turner's syndrome.
