RESUMO
Introduction: Psychotic symptoms are among the least prevalent and under-investigated psychiatric manifestations (PM) of Huntington's disease (HD). Case report: We herein report a case of a 31-year-old male patient who presented PM with a predominance of negative symptoms, without any significant abnormal movement. HD was diagnosed based on positive DNA analysis and family history. HD imposes longitudinal follow-up through a multidisciplinary approach in order to improve the quality of life and prognosis. Conclusion: This case report highlights the importance of comprehending the PM in the initial presentation of HD so that the diagnosis is not delayed until the onset of motor symptoms.
Introdução: Os sintomas psicóticos estão entre as manifestações psiquiátricas (MP) menos prevalentes e pouco investigadas da doença de Huntington (DH). Relado de caso: Relatamos o caso de um paciente do sexo masculino, 31 anos, que apresentou MP com predomínio de sintomas negativos, sem qualquer movimento anormal significativo. A DH foi diagnosticada com base em uma análise de DNA positiva e na história familiar. A DH impõe um acompanhamento longitudinal por meio de uma abordagem multidisciplinar, a fim de melhorar a qualidade de vida e o prognóstico. Conclusão: Este relato de caso destaca a importância da compreensão das MPs na apresentação inicial da DH, para que o diagnóstico não seja atrasado até ao aparecimento dos sintomas motores

Myocardial iron quantification remains limited to 1.5 T systems with T2* measurement. The present study aimed at comparing myocardial T2* values at 1.5 T to T1 and T2 mapping at 3.0 T in patients with iron overload and healthy controls. A total of 17 normal volunteers and seven patients with a history of myocardial iron overload were prospectively enrolled. Mid-interventricular septum T2*, native T1 and T2 times were quantified on the same day, using a multi-echo gradient-echo sequence at 1.5 T and T1 and T2 mapping sequences at 3.0 T, respectively. Subjects with myocardial iron overload (T2* < 20 ms) in comparison with those without had significantly lower mean myocardial T1 times (868.9 ± 120.2 vs. 1170.3 ± 25.0 ms P = 0.005 respectively) and T2 times (34.9 ± 4.7 vs. 45.1 ± 2.0 ms P = 0.007 respectively). 3 T T1 and T2 times strongly correlated with 1.5 T, T2* times (Pearson's r = 0.95 and 0.91 respectively). T1 and T2 measures presented less variability than T2* in inter- and intra-observer analysis. Native myocardial T1 and T2 times at 3 T correlate closely with T2* times at 1.5 T and may be useful for myocardial iron overload quantification.
