Third molar development was assessed using a sample of 1,131 orthopantomograms from a Portuguese population. The methodology applied was the eight stages (A-H) method described by Demirjian et al. The final sample was made of 739 orthopantomograms, 387 (52.5%) of which belonging to females; age ranged between 6.1 and 22.5 years old (mean age=14.49, S.D.=4.37). For each developmental stage, mean age, standard deviation, and minimal and maximal age was assessed; evaluation of the rate formation of each tooth, according to sex, was calculated and data distribution expressed in percentiles for each stage; the probability of an individual being 16 was also evaluated. The relationship between tooth development and chronological age had a statistical significance for all teeth and both sexes (p<0.0001). The data described may provide reference for forensic application and agree with the thesis that each population need specific data. © 2010 Springer-Verlag. Source

One-hundred and nine unrelated and healthy males from Santa Catarina, Brazil were included in this study. Allele frequencies and gene diversities for the loci DYS456, DYS458 and DYS448 were calculated. A comparison between our population and others was performed. © 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine. Source

Forensic age determination has become increasingly important over the past few years. Dental age estimation is frequently used as a part of this process due to the technique simplicity and reliability. This process is done taking into account pre-established values that, often, concern the population of the undocumented person. In this manner, population parameters are needed. In this paper, the authors present data concerning the third molar eruption in a Portuguese population: The minimum age for alveolar emergence of third molars ranged from 6.6 to 11.3 in females and 7.4 to 8.3 in males, for gingival emergence was 11.1 to 15.1 for females and 8.3 to 14.4 in males and for complete emergence was 15.9 to 19.4 in females and 13.4 for males. Complete emergence was found to be a useful marker for diagnosing age inferior 16 years, both in males and females, with 99.2% and 99.3% of correct predictions, respectively. These findings point out that it is possible to estimate the age of investigated persons based on alveolar, gingival and complete emergence of the third molars in the occlusal plane. © Springer-Verlag 2011.

"Takotsubo" cardiomyopathy (also known as stress cardiomyopathy or "broken heart syndrome") is a recently recognised transient condition that frequently mimics acute coronary syndrome. It is typically precipitated by acute emotional stress. Elder abuse is the infliction of physical, emotional or psychological harm on an older adult. As in other forms of abuse, elder abuse is a complex problem, easily prone to misconceptions and, therefore, to under-reporting. Herein, the authors present a case of a 76-year-old Caucasian woman, living in a dysfunctional family environment, who presented to her local Emergency Department with acute chest pain following an altercation with her daughter. Diagnostic criteria for "takotsubo" cardiomyopathy were met, namely, ST-segment elevation and T-wave changes, a mild increase of cardiac enzymes, an akinesia of the mid-portion and apex of the left ventricle and no significant epicardial coronary artery disease. The victim was admitted to the Cardiac Department on the second day and her condition improved over the following week. She was discharged and sent home after the situation was reported to competent authorities and subsequently to medico-legal services, who assessed the situation while still in-hospital. The case implications are discussed, as well as the impact that such cases may have when addressing elder abuse management and prevention, with a view to improving the forensic examination of these patients. © 2011 Springer Science+Business Media, LLC.
