When anthropometric methods were introduced into clinical practice to quantify changes in the craniofacial framework, features distinguishing various races/ethnic groups were discovered. To treat congenital or post-traumatic facial disfigurements in members of these groups successfully, surgeons require access to craniofacial databases based on accurate anthropometric measurements. Normative data of facial measurements are indispensable to precise determination of the degree of deviations from the normal. The set of anthropometric measurements of the face in the population studied was gathered by an international team of scientists. Investigators in the country of the given ethnic group, experienced and/or specially trained in anthropometric methods, carried out the measurements. The normal range in each resultant database was then established, providing valuable information about major facial characteristics. Comparison of the ethnic groups' databases with the established norms of the North America whites (NAW) offered the most suitable way to select a method for successful treatment. The study group consisted of 1470 healthy subjects (18 to 30 years), 750 males and 720 females. The largest group (780 subjects, 53.1%) came from Europe, all of them Caucasians. Three were drawn from the Middle-East (180 subjects, 12.2%), five from Asia (300 subjects, 20.4%) and four from peoples of African origin (210 subjects, 14.3%). Their morphological characteristics were determined by 14 anthropometric measurements, 10 of them used already by classic facial artists, Leonardo da Vinci and Albrecht Dürer, complemented by four measurements from the nasal, labio-oral and ear regions. In the regions with single measurements, identical values to NAW in forehead height, mouth width, and ear height were found in 99.7% in both sexes, while in those with multiple measurements, vertical measurements revealed a higher frequency of identical values than horizontal ones. The orbital regions exhibited the greatest variations in identical and contrasting measurements in comparison to NAW. Nose heights and widths contrasted sharply: in relation to NAW the nose was very or extremely significantly wide in both sexes of Asian and Black ethnic groups. Among Caucasians, nose height significantly differed from NAW in three ethnic groups, with one shorter and two greater. In the Middle Eastern groups nose width was identical to those of NAW but the height was significantly greater. The present study, conducted by investigators working separately across the world and with small samples of the population, is clearly preliminary in nature and extent. Yet it may fulfill its mission if medical and anthropological investigators continue the work of establishing normative data of the face. These data are urgently needed by medical professionals but have been lacking up till now in western and northern Europe, Asia, and Africa.

Th e aim of our study was to report a series of  consecutive patients with aneurysms of the proximal segment (A) of the anterior cerebral artery. In  patients with diagnosed A aneurysms, representing . of  aneurysm patients treated at a University Clinical Center between October  and August , clinical presentation, neuroradiological fi ndings, surgical treatment methods and outcome were retrospectively analyzed. Mean patient age was . (range  to ) years. Ten saccular aneurysms were treated with micro neurosurgical approach via standard pterional craniotomy, four fusiform aneurysms with coiling, and one fusiform aneurysm with stent. No patients died during the operation. Th e mean follow-up period was  months (range  months to  years). Clinical outcomes revealed good recovery in all patients. Despite the general opinion that A aneurysms are benign lesions, an increasing number of reports have demonstrated their potential complications. To date, due to the rarity of A aneurysms, only a few consecutive series have been reported. Conduct of multicenter studies are required in order to understand clinical features of A aneurysms and devise a proper treatment plan.©  Association of Basic Medical Sciences of FB&H.

The purpose of the work was to study the features of reparative osteogenesis for filling the defect of tubular bone under implantation of mesh titanium nickelide constructs. Tibial fenestrated defect was modeled experimentally in 30 Wistar pubertal rats, followed by implant intramedullary insertion. The techniques of radiography, scanning electron microscopy and X-ray electron probe microanalysis were used. The mesh implant of titanium nickelide has been established to possess biocompatibility, osteoconductive and osteoinductive properties, the zone of osteogenesis and angiogenesis is created around it, bone cover is formed. Osteointegration of the implant occurs early, by 7 days after surgery, and by 30 days after surgery organotypical re-modelling of the regenerated bone takes place, as well as the defect is filled with lamellar bone tissue by the type of bone wound primary adhesion. By 30 days after surgery mineral content of the regenerated bone tissue approximates to the composition of intact cortex mineral phase.

The dentists’ main job is to restore health and function to the oral cavity. However, dental professionals can also be involved in medico legal activities as forensic odontologists or by being Expert Witnesses (EW) to testify in professional liability cases, car accidents and work-related injuries. When called to act as an expert witness by the Court, the appointed dentist has to combine both biological and technical knowledge with equivalent medico-legal and forensic knowledge. Spontaneous involvement in medico-legal matters without an adequate training and experience can lead to mistakes with irreversible consequences. As an expert witness, the dentist has precise responsibility with civil and/or penal consequences, depending on the national judicial system. Dental Expert Witness, working either privately or appointed by the Court, has defined responsibilities and is subjected to civil or criminal proceedings (depending on the judicial system) if found wanting. Keeping in mind that there are significant differences regarding the requirements of becoming eligible to be a Dental Expert Witness in different legal systems. In this work the authors investigated the Judicial Systems regarding the appointment of Dental Expert Witnesses in Brazil, Croatia, Indonesia, Italy, Saudi Arabia and the United Kingdom (Table 1), in order to marshal knowledge towards harmonization and the attainment of best practice. This premise acknowledges the fact that forensic odontology must encompass the necessity for robust systems of audit and accreditation for it to be accepted as an “evidence based” forensic discipline. Further steps to ensure quality assurance in legal dentistry and forensic odontology training should be considered to prevent the spontaneous involvement of inappropriately trained dentists to become involved in making decisions that are beyond their competence and expertise.
