Forensic-medical obstetric-gynecological examinations in cases on professional delinquency of medical personnel

We studied the trend in the number of forensic-medical examinations in trials against obstetricians and gynecologists conducted in Primorsky Region in 1997-2005. Most typical defects in obstetric-gynecological care are characterized. These cases are analysed in terms of forensic-medical practice. Detection and forensic-medical analysis of the above defects contribute to optimization of the diagnosis and treatment both in obstetric-gynecological practice and in wide medical practice.     

Effect of clothes on the size of gunshot wounds made by long-distance shots with small-calibre bullets

An experimental study was made on estimation distance of shots made from far distance through clothes with 5.6-mm jacket-free lead bullets. Textile obstructions imitating human clothes were modeled. Contact velocity of the wounding bullet was measured. Almost complete forensic-medical characteristics of inlet gunshot wounds of the body allowing for clothes properties, anatomic structure of the affected body area, deformation of the hitting bullets were obtained.     

Morphology of acute lung injuries in mechanic trauma

The lungs from 60 subjects who had died of polytrauma were studied morphologically. The heads of the corpses were not injuried. The aim of the study was investigation of characteristics and time of development of structural changes associated with lung injury. Early structural changes in trauma were disorders of circulation including microcirculation, acute emphysema, distelectases and atelectases, injury of bronchial and bronchiolar mucosa. Pulmonary edema and systemic inflammatory reaction emerge in the first hours after trauma.     

Chemicotoxicological evaluation of doxylamine

The conditions of doxilamine isolation from biological fluids are studied. The method of its extraction with a mixture of organic solvents in pH 9 is proposed. Identification of doxilamine with techniques of thin layer chromatography, UV-, IR-spectroscopy, chromato-mass-spectrometry, densitometry, gas-liquid chromatography is described. UV-spectrometry, gas chromatography and densitometry can be used for quantitation of doxilamine.     

Detection of antimony topography using diffuse-contact method on the skin targets of bio-manikins after shooting with Makarov gun from short distance

The authors examined sedimentation of stibium in the area of experimental skin entry holes generated by Makarov gun shots from different distances. Regularities of allocation of stibium subject to the distance of the shot were determined. Practical recommendations for expert conclusion about the distance of the shot were given on the grounds of the results of the study.     

Forensic-medical assessment of diaphysis fractures in childhood

The authors established that special structure of bones in childhood have a significant influence on the fractures of long tubular bones. The formation of unusual fractures shows it. Under condition of low speed of bending in the area of fracture many microfissures are formed, which leads to structural failure of intraosseous microcirculation and osteocytes.     

Child Abuse-Related Homicides in New Mexico: A 6-year Retrospective Review

Abstract:  We retrospectively reviewed autopsy records at a statewide medical examiner's office in order to identify and characterize deaths due to child abuse. In a 6-year period in New Mexico, the medical examiner investigated 45 deaths determined to be child abuse-related. Decedents were predominantly male (68.9%), Hispanic White (53.3%), and all were 5 years of age or younger, with a median age of 1 year. Head injuries were the most common cause of death (44.4%), followed by battered baby syndrome (15.6%). Relatives were involved as alleged perpetrators in 80% of the cases, with the father most often implicated (36.1% of cases), and 88.9% of child abuse injuries resulting in death occurred in the family's residence. Toxicology was positive in 26.7% of cases, but only two cases had substances of abuse present. Information on risk factors such as prematurity, parental age, and history of abuse was also collected.     

DETECHIP®: A Sensor for Drugs of Abuse*

Abstract: The design and preliminary characterization of a novel sensor for drugs of abuse, DETECHIP^®, is described in this proof‐of‐concept note. Combining both colorimetric and fluorimetric assays, DETECHIP^® is suitable for lab and field use. More than a conventional spot test which provides a single “yes or no” answer, DETECHIP^® provides twenty responses for a more complete characterization of suspect material. This is accomplished by visually noting colorimetric and fluorescent changes of carefully selected dyes upon the addition of test analytes, including drugs of abuse, with respect to controls. Color and fluorescence changes are recorded numerically so that a 20 digit identification code can be constructed for comparison of test analytes and known compounds. DETECHIP^® is applicable to a variety of drugs, both plant‐derived and synthetic, addressing the need to use several different spot tests simultaneously for a single sample.
