The subtle anatomical structures of normal nasal bone in MSCT image and forensic identification / 法医学杂志

OBJECTIVE@#To summarize the subtle anatomical structures of the normal nasal bone in multi-slice spiral CT (MSCT) image through the observation of the three-dimensional images.@*METHODS@#One hundred and twenty volunteers who had no nasal trauma and disease history were collected. The nasal was scanned using MSCT. Raw data was reconstructed into bone window images (slice thickness 0.6 mm, slice interval 0.5 mm), and then the images were imported into Syngo Imaging XS software to reconstruct three-dimensional images and to summarize the nasal bone's subtle anatomical structures.@*RESULTS@#The subtle anatomy of normal nasal bone generally included four seams, two holes and one edge. The four seams were left and right nasal-maxillary suture, nasal-frontal seam, and internasal suture. The two holes were left and right nasal aperture. The edge of the nasal was the lower edge of the nasal bone. In addition, there was suture bone in internasal suture in some normal nose. The nasal aperture mostly was hole-like, but some nasal apertures were line shape. The nasal edge can be divided into flat type, wave-shaped type, inverted spike type, hook-shaped type and others.@*CONCLUSION@#The anatomy diversity and individual differences in nasal bone are large. MSCT and three-dimensional image reconstruction techniques, combined with the history of trauma could distinguish between the normal anatomy and fractures.

Cause of death related to medical disputes in Yancheng area: a study of 60 autopsy cases / 法医学杂志

OBJECTIVE@#To summarize the pattern and main characteristics of fatal cases related to medical disputes in Yancheng area.@*METHODS@#Sixty fatal cases of medical disputes were retrospectively analyzed to elucidate the annual incidence, characters of distribution of hospitals, gender and age of the decedents, types of diseases, and cause of death.@*RESULTS@#Among 60 fatal cases, most cases happened in health clinics of county, township and village. There were more males than females. The major medical specialties involved included internal medicine, surgery, gynecology and pediatrics, with the internal medicine specialty having the highest incidence.@*CONCLUSION@#Police institutions have advantages in investigation of these cases in their jurisdictions, which could enhance the ability of local medicolegal examination.

Forensic evidence-based medicine in computer communication networks / 法医学杂志

As an important component of judicial expertise, forensic science is broad and highly specialized. With development of network technology, increasement of information resources, and improvement of people's legal consciousness, forensic scientists encounter many new problems, and have been required to meet higher evidentiary standards in litigation. In view of this, evidence-based concept should be established in forensic medicine. We should find the most suitable method in forensic science field and other related area to solve specific problems in the evidence-based mode. Evidence-based practice can solve the problems in legal medical field, and it will play a great role in promoting the progress and development of forensic science. This article reviews the basic theory of evidence-based medicine and its effect, way, method, and evaluation in the forensic medicine in order to discuss the application value of forensic evidence-based medicine in computer communication networks.
