Report of the Skin Research Working Groups from the GRAPPA 2021 Annual Meeting.

The International Dermatology Outcome Measures (IDEOM) initiative presented an update on their progress related to instruments for psoriasis (PsO) and psoriatic arthritis (PsA) patient-centered outcome measures at the 2021 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). The Treatment Satisfaction working group presented the development of a 7-item treatment satisfaction questionnaire specific for dermatological conditions. The group is beginning by assessing the validity and reliability of the instrument in PsO patient populations, with the ultimate goal of validating it for use in multiple dermatological diseases.

Familial clustering of tic disorders and obsessive-compulsive disorder.

Importance: Tourette syndrome/chronic tic disorder (TS/CT) and obsessive-compulsive disorder (OCD) overlap in their phenomenological features and often co-occur in affected individuals and families. Understanding how these disorders cluster in families provides important clinical information and is an important step in understanding the causes of these disorders.

Objective: To determine familial recurrence for TS/CT and OCD using a national epidemiologic sample.

Interleukin-1 deficiency prolongs ovarian lifespan in mice.

Oocyte endowment dwindles away during prepubertal and adult life until menopause occurs, and apoptosis has been identified as a central mechanism responsible for oocyte elimination. A few recent reports suggest that uncontrolled inflammation may adversely affect ovarian reserve. We tested the possible role of the proinflammatory cytokine IL-1 in the age-related exhaustion of ovarian reserve using IL-1α and IL-1β-KO mice.
