"Documentary sources refer to leprosy patients in the Portuguese territory since the first century AD, and in the Middle Ages around 70 leprosaria were established. However, prior to 2003 this historical evidence had not been confirmed by archeological findings. The excavation performed in monitoring the rehabilitation done by the Polis program in the area of the Ermida de Santo André (hermitage of Saint Andrew) allowed the exhumation of seven human skeletons, and commingled bones from at least three individuals, in the vicinity of the Beja leprosarium. The objective of this study is to present the paleopathological lesions relevant to the discussion of the differential diagnosis of leprosy. Macroscopic observation of the bones and scrutiny of lesions according to the paleopathological literature allowed the identification of a probable case of leprosy in an adult male, showing rhinomaxillary changes and concentric remodeling of hand and foot bones, and four possible cases (two young adults and two adults, all probably males), with a set of lesions in facial bones and skeletal extremities. The poor preservation of the bones precluded further confirmation of this diagnosis. According to historical data, the leprosaria functioned between the 14th and 16th centuries AD. The exact chronology of these findings was not determined either during the excavation or by radiocarbon dating because the bones presented poor collagen levels. In Portugal as a whole there are few osteological evidences of leprosy, and thus this study adds new information about this chronic infectious disease.

Sex determination in forensic dentistry is a major step towards postmortem profiling. The most widely recognized method is DNA, yet its application in the dental field of forensic sciences is still impractical. Depending on the conditions of the remains, teeth are often the only surviving organ. Some systematic reviews (SRs) have been recently produced; hence this umbrella review critically assesses their level of evidence and provides an overall comprehensive view. An electronic database search was conducted in four databases (PubMed, Cochrane, Web of Science, and LILACS) and three grey search engines up to December 2021, focusing on SRs of sex determination through forensic dentistry procedures. The methodological quality of the SRs was analyzed using the measurement tool to assess SRs criteria (AMSTAR2). Five SRs were included, two of critically low quality and three of low quality. The SRs posited that canines are the most dimorphic teeth; oral tissue remnants are a rich source for sex determination by DNA tracing; and artificial intelligence tools demonstrate high potential in forensic dentistry. The quality of evidence on sex determination using dental approaches was rated as low. Well-designed clinical trials and high standard systematic reviews are essential to corroborate the accuracy of the different procedures of sex determination in forensic dentistry.

Accurate sex prediction is a key step in creating a postmortem forensic profile as it excludes approximately half the population. It is our goal to develop a predictive model to establish sex through teeth mesiodistal widths in a Portuguese population. The pretreatment dental casts of 168 of Portuguese orthodontics subjects (59 males and 109 females) were included. Mesiodistal widths from right first molar to left first molar were measured on each pretreatment cast to the nearest 0.01 mm using a digital caliper. Overall, the mesiodistal widths of the upper and lower canines, premolars, and molars were found to be significantly different between females and males. Conversely, no significant differences between sexes were identified for incisors. A multivariate logistic regression model for sex prediction was developed and the teeth included in the final reduced model being the upper left canine (2.3), the lower right lateral incisor (4.2) and the lower right canine (4.3). There is a prevalence of sexual dimorphism in all teeth except the incisors. The canines present the most noticeable difference between sexes. The presented sex determination predictive model exhibits an overall correct classification of 75%, outperforming all available models for this purpose and therefore is a potential tool for forensic analysis in this population.

An archaeological survey at the church of Nossa Senhora da Anunciada (Setúbal, Portugal) uncovered the remains of 92 individuals. Historical and archaeological data suggest that the inhumations occurred between 1531 and 1839. The present work reports the pathological features of a mature male individual exhibiting multiple osseous bony projections and bone deformity, mainly affecting the metaphyseal and adjacent diaphyseal regions of the long bones. The macroscopic and the radiological analyses of the lesions suggest multiple osteochondromas as the most probable diagnosis. This is the first archaeological case of this disease known on the Portuguese territory and in southern Europe.info:eu-repo/semantics/publishedVersio
