The first step in an investigation of quantitative ultrasound as a technique for evaluating infant bone strength.

This study's purpose is to evaluate whether bone speed of sound (SOS) data, a parameter of quantitative ultrasound, collected from an infant autopsy sample are comparable to data collected from healthy, living infants. We hypothesize that SOS values obtained from deceased term-born infants will fall within the normal range for healthy, living infants. The study sample consists of 351 deceased infants between the ages of 30 weeks gestation at birth to 1 year postnatal at the time of death receiving autopsies at the Harris County Institute of Forensic Sciences or Texas Children's Hospital in Houston, TX.

The Infant Injury Database: A Tool for the Study of Injury Patterns in Medicolegal Investigations of Child Abuse.

In 2012, the Harris County Institute of Forensic Sciences began prospectively collecting injury data from pediatric autopsies. These data and associated case information from 635 pediatric cases are archived in the Infant Injury Database (IID). This paper introduces the IID to the forensic community and demonstrates its potential utility for child abuse and infant fatality investigations.

The Role of the Anthropologist in Identification at Two Urban Medical Examiner Offices: New York City and Harris County.

Two urban jurisdiction medical examiner offices, the New York City Office of the Chief Medical Examiner (NYC OCME) and the Harris County Institute of Forensic Sciences (HCIFS), receive large numbers of unidentified decedents each year. In 2015, the NYC OCME received over 400 decedents whose identities were initially reported as unknown. The HCIFS received 226 unknown decedent cases in 2015.

Microscopic saw mark analysis: an empirical approach.

Microscopic saw mark analysis is a well published and generally accepted qualitative analytical method. However, little research has focused on identifying and mitigating potential sources of error associated with the method. The presented study proposes the use of classification trees and random forest classifiers as an optimal, statistically sound approach to mitigate the potential for error of variability and outcome error in microscopic saw mark analysis.

A proposed scheme for classifying pediatric rib head fractures using case examples.

Pediatric rib head fractures are typically described as "posterior" or "costovertebral," terms lacking specificity. To resolve this issue, a scheme was developed to describe the location of rib head fractures observed in a pediatric forensic population. The scheme uses three anatomical landmarks, terminus (tip), tubercle, and costovertebral articular surface to divide the rib head into two subregions, costovertebral and costotransverse.

Standardized descriptive method for the anthropological evaluation of pediatric skull fractures.

The literature pertaining to pediatric skull fracture is primarily clinically based and thus motivated by the need for effective assessment of both fracture characteristics (type, frequency, location, and mechanics) and context (severity of injury, associated soft tissue damage, and prognosis). From a strictly descriptive standpoint, these schemas employ overlapping levels of detail that confound the nonclinical description of fractures in the forensic context. For this reason, application of these schemas in the forensic anthropological interpretation of skull fractures is inappropriate.

Development of a computer-assisted forensic radiographic identification method using the lateral cervical and lumbar spine.

Medical examiners and coroners (ME/C) in the United States hold statutory responsibility to identify deceased individuals who fall under their jurisdiction. The computer-assisted decedent identification (CADI) project was designed to modify software used in diagnosis and treatment of spinal injuries into a mathematically validated tool for ME/C identification of fleshed decedents. CADI software analyzes the shapes of targeted vertebral bodies imaged in an array of standard radiographs and quantifies the likelihood that any two of the radiographs contain matching vertebral bodies.

Novel classification system of rib fractures observed in infants.

Rib fractures are considered highly suspicious for nonaccidental injury in the pediatric clinical literature; however, a rib fracture classification system has not been developed. As an aid and impetus for rib fracture research, we developed a concise schema for classifying rib fracture types and fracture location that is applicable to infants. The system defined four fracture types (sternal end, buckle, transverse, and oblique) and four regions of the rib (posterior, posterolateral, anterolateral, and anterior).

Preservation of evidence during pediatric organ donation: a modified thoracotomy procedure designed to increase consent in medical examiner cases.

Deceased potential organ donors are often under the jurisdiction of medical examiners/ coroners. In these deaths, the medical examiner/coroner has the statutory responsibility of determining cause and manner of death but is also responsible for presenting findings from the complete autopsy in court. The ability to analyze findings such as location, nature, and age of rib fractures and patterned skin injuries may be crucially important to legal disposition, even though those findings may not be critical to determination of cause and/or manner of death.

Postmortem findings in eight cases of influenza A/H1N1.

In March and early April 2009, cases of a new swine-origin influenza A (H1N1) virus were diagnosed in Mexico and the United States. Influenza virus presents as a respiratory infection with high morbidity and mortality. We describe the postmortem findings of eight confirmed cases of influenza A/H1N1 in a medical examiner setting.

Undetermined cause and manner of death after organ/tissue donation.

The Harris County Medical Examiner's Office (HCME) is proactive and supportive with regard to organ and tissue donation. Steps taken to facilitate donation include development of standardized multiagency protocols for organ/tissue requests and transfer of decedents out of the facility for tissue recovery prior to autopsy. The organ/tissue agencies have 24-hour access to a liaison staff member.
