Impulsivity in Depression: Its Relation to Suicidality

Pediatric suicide: Review of a preventable tragedy

Concepts of suicide are explored in this issue with a focus on suicide in children and adolescents. The epidemiology of pediatric suicide in the United States is reviewed; also, risk and protective factors, as well as prevention strategies, are discussed. Suicide in the pediatric athlete and the potential protective effect of exercise are examined. In addition, this analysis addresses the beneficial role of psychological management as well as current research on pharmacologic treatment and brain stimulation procedures as part of comprehensive pediatric suicide prevention. Though death by suicide in pediatric persons has been and remains a tragic phenomenon, there is much that clinicians, other healthcare professionals, and society itself can accomplish in the prevention of pediatric suicide as well as the management of suicidality in our children and adolescents.

No association between isotretinoin and impulsivity in patients with moderate-to-severe acne vulgaris

BACKGROUND

Acne vulgaris (AV) is one of the common dermatologic diseases that usually affects people during adolescence. Reports have shown that isotretinoin, the first-line therapy option for moderate-to-severe AV, could lead to mood disturbances and suicidality. Impulsivity is the tendency to act prematurely without foresight and is a significant risk factor for suicidality. This study aimed to test the hypothesis that isotretinoin would lead to an increase in impulsivity.

METHODS

Seventeen patients with AV were enrolled. The study was planned as a naturalistic 3-month follow-up study. Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Barratt Impulsiveness Scale (BIS), Go/No-go Task (GNG), and Balloon Analog Risk Task (BART) were administered before and after the isotretinoin treatment.

RESULTS

We found a significant improvement in the severity of anxiety (P = 0.015; t = 2.72) and depression symptoms (P = 0.08; t = 3.04) in AV patients at the end of 3 months. Self-report impulsivity characteristics with BIS stayed unchanged (P = 0.434; t = 0.80). Besides, no statistically significant difference was found in behavioral task results associated with response inhibition with GNG (P = 0.52; t = 0.65) and impulsive decision-making with BART (P = 0.842; t = -0.20). However, there was a significant decrease in omission errors, with GNG suggesting improvement in attention domain (P = 0.020; W = 90.0) after the follow-up.

CONCLUSIONS

It has been demonstrated that isotretinoin treatment improves the severity of depression, anxiety symptoms, and attention performance in AV patients. However, there was no significant change in patients' impulsivity severity based on self-reports and behavioral performances based on GNG and BART.
