Human cranial vault thickness in a contemporary sample of 1097 autopsy cases: relation to body weight, stature, age, sex and ancestry.

The relation between human cranial vault thickness (CVT) and various elements of the physical anthropological biological profile is subject of ongoing discussion. Some results seem to indicate no correlation between CVT and the biological profile of the individual, whereas other results suggest that CVT measurements might be useful for identification purposes. This study assesses the correlation between CVT and body weight, stature, age, sex, and ancestry by reviewing data of 1097 forensic autopsies performed at the Netherlands Forensic Institute (NFI). In subadults (younger than 19 years of age at the time of death), all frontal, temporal, and occipital CVT measurements correlated moderately to strongly with indicators of growth (body weight, stature, and age). Neither sex nor ancestry correlated significantly with cranial thickness. In adults, body weight correlated with all CVT measurements. No meaningful correlation was found between CVT and stature or age. Females showed to have thicker frontal bones, and the occipital region was thicker in the Negroid subsample. All correlation in the adult group was weak, with the distribution of cranial thickness overlapping for a great deal between the groups. Based on these results, it was concluded that CVT generally cannot be used as an indicator for any part of the biological profile.

An accessory skull suture mimicking a skull fracture.

This paper describes an investigation of the sudden and unexpected death of a five-and-a-half-month-old boy. As in every Dutch case of sudden unexpected death in infancy (SUDI), a multidisciplinary diagnostic approach was used. This included post-mortem radiography, showing a linear discontinuity of the parietal bone. Originally this was interpreted as a skull fracture, but autopsy indicated no signs of mechanical trauma. Instead the defect was defined as a unilateral accessory suture of the parietal bone. The initial erroneous diagnosis had severe adverse consequences and thus every health care professional or forensic specialist dealing with paediatric mechanical traumas should be cautious of this rare anomaly.

The value of post-mortem CT in neonaticide in case of severe decomposition: description of 12 cases.

INTRODUCTION: In cases of neonaticide with delayed finding of the body, interpretation of autopsy results can be difficult because of decomposition. Postmortem computed tomography (PMCT) has become an increasingly popular tool in the (pediatric) forensic field. We performed a retrospective study to compare the outcome of PMCT with autopsy results in suspected neonaticide, in neonates found more than one week after their demise. We compared the performance of both methods on (1) determining gestational age, (2) differentiating between live birth and still birth and (3) determining cause of death. METHOD: We selected all consecutive neonaticide cases with an estimated postmortem interval longer than one week, who underwent a forensic autopsy including a total body PMCT in the Netherlands Forensic Institute in the period 2008-2012. Both a pathologist and radiologist scored gestational age, signs of live birth and cause of death for each case. RESULTS: 22 cases of neonaticide were identified in the study period, of which 15 cases were estimated to be found more than 1 week after death. In 12 of these a total body PMCT was performed. In all cases, late postmortem changes were present. Gestational age could be assessed with PMCT in 100% of the cases and with autopsy in 58% of the cases. In all cases neither PMCT nor autopsy was able to assess live birth and cause of death. CONCLUSION: PMCT is a better tool for estimating gestational age in case of suspected neonaticide with late postmortem changes compared to autopsy and should therefore be a standard part of the work-up. Signs of live birth and cause of death could not be determined with neither of the methods, an adjusted post mortem examination including limited autopsy for these cases might be developed.

A case of fatal coin battery ingestion in a 2-year-old child.

Foreign body aspiration is frequently encountered in young children, in the majority of cases it will not lead to an adverse outcome. However, in case of coin battery ingestion more serious adverse outcomes, including death, have been reported. We present a case with fatal outcome due to exsanguination, of a 2-year-old child with an aberrant right subclavian artery (or arteria lusoria) and coin battery ingestion. Radiological and autopsy findings and relevant literature are discussed.

Strategies for management of prostate cancer-related bone pain.

Prostate cancer is one of the most common malignancies and a leading cause of cancer-related death in men worldwide. In the majority of cases, prostate cancer metastases to the skeleton, in which case cancer-related bone pain becomes a major cause of morbidity. Androgen ablation is the treatment of choice for securing regression of skeletal metastases in the majority of cases. Intermittent androgen ablation is an attractive alternative, aimed at minimising adverse effects of hormone deprivation but also potentially delaying hormone-refractoriness. The development of hormone-refractoriness is heralded by a significant increase in morbidity largely because of escalating bone pain caused by the progression of the metastatic process. Skillful use of analgesics is initially successful but eventually fails to control symptoms. Localised metastases are best treated with local radiotherapy that is rapidly effective. Over the last few years, it has become clear that therapeutic modalities using bone-seeking radionuclides or bisphosphonates have been effective in the palliation of prostate cancer-related bone pain, although not affecting survival. The main limiting factor with the use of radionuclides is bone marrow suppression, also a feature of the very late stages of prostate cancer. Bisphosphonates do not carry this disadvantage. Results of large double-blind, placebo-controlled studies should be awaited, however, before advocating the widespread use of these agents in the management of patients with prostate cancer and skeletal metastases.
