This is the first epidemiological study on ADHD in older persons. With a prevalence of 2.8% the study demonstrates that ADHD does not fade or disappear in adulthood and that it is a topic very much worthy of further study.

Long-term outcome of burn scars as well as the relation with clinically relevant parameters has not been studied quantitatively. Therefore, we conducted a detailed analysis on the clinical changes of burn scars in a longitudinal setup. In addition, we focused on the differences in scar quality in relation to the depth, etiology of the burn wound and age of the patient. Burn scars of 474 patients were subjected to a scar assessment protocol 3, 6, and 12 months postburn. Three different age groups were defined (≤5, 5-18, and ≥18 years). The observer part of the patient and observer scar assessment scale revealed a significant (p < 0.001) improvement in scar quality at 12 months compared with the 3- and 6-month data. Predictors for severe scarring are depth of the wound (p < 0.001) and total body surface area burned (p < 0.001). Etiology (p = 0.753) and age (p > 0.230) have no significant influence on scar quality when corrected for sex, total body surface area burned, time, and age or etiology, respectively.

This retrospective study examined the predictive validity of the HCR-20, a violence risk assessment instrument. The HCR-20 as well as the Psychopathy Checklist-Revised (PCL-R) were coded on the basis of file information of 120 patients discharged from a Dutch forensic psychiatric hospital between 1993 and 1999 (average follow-up period 72.5 months). The patients were divided into four groups according to type of discharge: 1) discharge by the court in line with the hospital staff's advice and after a transmural phase; 2) discharge by the court in line with the hospital staff 's advice, but without a preceding transmural phase; 3) discharge by the court against the hospital staff's advice; and 4) readmission to another institution. Recidivism data (reconvictions) from the Ministry of Justice were related to the risk assessments. The base rate for violent recidivism was 36%, and 52% for general recidivism. The HCR-20 and PCL-R total scores demonstrated good predictive validity for violent recidivism (AUC = .82 and .75, respectively). The HCR-20 was a significantly better predictor of violent recidivism than unstructured clinical judgment stated in hospital staff 's advice to the court. In addition, the HCR-20 total score predicted significantly better than the PCL-R total score, although the difference in AUC values was no longer significant when the item ‘Psychopathy’ was removed from the HCR-20 total score.
