Twiddler's or twist syndrome is the twisting of pulse generators around themselves. It may result from mechanical manipulation that can induce the malfunction of the device. In this case, twiddler's syndrome resulted from compulsive checking of the device. The implantable cardioverter-defibrillator (ICD) triggered the development of an obsessive compulsive disorder (OCD). Two invasive procedures were required to replace the ICD. Psychiatric intervention prevented the recurrence of twiddler's syndrome in this patient for more than 2 years. We believe that preimplant psychiatric assessment should be the rule.
This study aimed to determine whether personality disorders were associated with later Major Depressive Disorder (MDD) or Generalised Anxiety Disorder (GAD) in breast cancer patients. This longitudinal and multicentric study included 120 French non-metastatic breast cancer patients. After cancer diagnosis (T1) and 7 months after diagnosis (T3), we assessed MDD and GAD (Mini International Neuropsychiatric Interview 5.0). We assessed personality disorders 3 months after diagnosis (VKP). We used multiple logistic regression analysis to determine what were the factors associated with GAD and MDD at T3. At T3, prevalence rate was 10.8% for MDD and 19.2% for GAD. GAD at T3 was significantly and independently associated with GAD at T1 and with existence of a personality disorder, no matter the cluster type. MDD at T3 was significantly and independently associated with MDD at T1 and with the existence of a cluster C personality disorder. Initial cancer severity and the type of treatment used were not associated with GAD or MDD at T3. Breast cancer patients with personality disorders are at higher risk for GAD and MDD at the end of treatment. Patients with GAD should be screened for personality disorders. Specific interventions for patients with personality disorders could prevent psychiatric disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
