The sacrum is a large trilateral bone located at the base of the vertebral column serving to transfer the body weight from the trunk to the pelvis and lower extremities. Over the years, an abundance of sacral anatomical divergences has been reported, including numerical and/or morphological variations of sacral entities. The majority of these anatomical alternations has been incidentally identified during radiological investigations, surgical procedures or discovered in anatomical, anthropological and forensic research studies. Throughout international literature, however, there is a scarcity of an integrative recording of all known anatomical variations of the sacrum in a single study. This constitutes the objective of the present paper: to provide an exhaustive systematic review of the relevant literature, as well as to thoroughly describe all the recognised deviations of the sacrum structure, while highlighting the aspects of their clinical significance.

Peripartum psychosis is a rare but serious psychiatric disorder characterized by the presence of a mood episode with psychotic features. Although controversy surrounds the nosological status of peripartum mental disorders, these conditions continue to be of exceptional interest to the medical and forensic mental health communities. The aim of this study was to report a rare case of prepartum psychosis which escalated to the endpoint of neonaticide and summarize literature on peripartum mental disorders and infanticide. A 30-year-old mother murdered her newborn with the spike of her serum delivery system and planned to commit suicide while in hospital after hallucinating due to an acute puerperal psychotic disorder with a prepartum onset and postpartum deterioration. Her disorder was not managed until neonaticide. Throughout this paper, the significance of a multidisciplinary approach for the optimal management of these incidents is highlighted and diagnostic as well as therapeutic issues are addressed.

Penetrating head injuries due to the use of screwdrivers as wounding agents in acts of interpersonal violence seldom occur. The aim of this article is to update and summarize the relevant literature on penetrating craniocerebral screwdriver stab wounds and to report a new case of screwdriver assault. A number of studies were reviewed to investigate the incidence, distribution, common findings, mechanism of injury, differential diagnostic criteria, complications, treatment, and prognosis of craniocerebral screwdriver stab injuries. It was observed that the degree of traumatic severity depends on the cross-sectional area of the screwdriver and the anatomical region of injury. Craniocerebral screwdriver injuries are mainly cases of interpersonal violence and the mortality rate is approximately 47.6%. In 23.8% of the incidents, the trauma is overlooked on admission because of the small entry wound and, thus, the severity of the injury is not initially appreciated.

The land borders of Evros, Greece, have been a common entry point for undocumented migrants on their way to Europe through Turkey. Adverse conditions, however, have resulted in many human casualties over the years. On the Greek side, 334 cadavers were retrieved between 2000 and 2014. This study provides a detailed forensic account of the humanitarian disaster in Evros to create an official scientific record of the situation. It showcases the gravity of the global issue of migration relating to health and mortality, and encourages communication and continual improvement of the approach and patterns of practices surrounding the subject. A retrospective statistical research review was conducted of border‐related fatalities between 2000 and 2014, assessing the age and gender of victims, the cause of death, the location of bodies, identification rates, and country of origin. Age ranged generally from 24 to 29 years, but infants and children were among the deceased.
