Markers of bone turnover were analysed, and associations with outcomes explored. Dual-energy X-ray absorptiometry (DXA) was used to measure BMD of the whole body and lumbar spine (spine) in all participants, and of ultra-distal radius, forearm and total hip in participants ≥20y only. JDM patients (n = 59) were examined median 16.8y (range 6.6–27.0y) after disease onset and compared with 59 age/sex-matched controls. In this study we compare BMD in patients (children/adolescence and adults) with long-standing JDM with matched controls and in patients, explore how general/disease characteristics and bone turnover markers are associated with BMD. Both the disease and its treatment with glucocorticoids may negatively impact bone formation. Juvenile dermatomyositis (JDM) is the most common idiopathic inflammatory myopathy in children and adolescents. Further studies are needed to understand the extent of BMD abnormalities and the effect of gonadectomy, especially early in childhood, and to establish the optimal HRT regimen for bone accrual. These limited data indicate that adolescents with CAIS have bone mass deficit. Among those with gonadectomy, LBMD-Z was −1.8 (−3.59 to 0.49) at age 15.6 years (12–16.8) and decreased in all three subjects who had longitudinal follow-up despite hormone replacement therapy (HRT). In the subject with intact gonads, LBMD-Z and TBLH BMC-Z were −1.56 and −1.26, respectively, at age 16 years. Six females with genetically confirmed CAIS were identified-one with intact gonads and five with history of gonadectomy at 2–11 months. Results are expressed as median and min, max. Z-scores for lumbar spine areal BMD (LBMD), total body less head (TBLH), bone mineral content (BMC), LMI, and FMI were calculated using female normative data. Body composition is presented as lean and fat mass indices (LMI, FMI). Single-center, retrospective study of CAIS adolescents who underwent dual-energy x-ray absorptiometry (DXA) (Hologic, Horizon A). Body composition data have not been reported. Little is known about changes in bone mineral density (BMD) in adolescents with CAIS and whether it is affected by early gonadectomy. Osteopenia and osteoporosis have been reported in adults with Complete Androgen Insensitivity Syndrome (CAIS). Not much has been written on the influence of drugs on the skeleton from the forensic anthropological practitioner perspective and this review, in spite of its limitations and the requirement of further research, aims to investigate the current knowledge of the possible effects of both prescription and recreational drugs on bones, contributing to providing a better awareness in forensic anthropological practice and assisting in the identification process of the deceased. Through different mechanisms, drugs can alter bone mineral density, causing osteopenia, osteoporosis, increase the risk of fractures, osteonecrosis, and oral changes. The information gathered from the clinical and medical literature has been extracted with a forensic anthropological perspective and provides an awareness on how several drugs, such as opioids, cocaine, corticosteroids, non-steroidal anti-inflammatory drugs, alcohol, tobacco and others have notable effects on bone. Moreover, it may be that the observation of certain alterations or inconsistencies in the skeleton may relate to the use of drugs or medication, and this in turn may help narrow down the list of missing persons to which a set of human remains could belong. In view of this, this paper aims to review the medical, clinical and pharmacological literature to enable an assessment of those drug groups that as side effects have the potential to have an adverse effect on the skeleton, and explore whether or not they can influence the estimation of age-at-death, sex and other indicators of the biological profile. During the examination of human remains, it is important to be aware that the skeletal features considered when applying anthropological methods may be influenced and modified by a number of factors, and particular to this article, prescription drugs (including medical and non-medical use) and other commonly used drugs. Forensic anthropologists rely on a number of parameters when analyzing human skeletal remains to assist in the identification of the deceased, predominantly age-at-death, sex, stature, ancestry or population affinity, and any unique identifying features.
