Butterfly vertebra. A case report and a short review of the literature

A butterfly vertebra is a rare congenital anomaly, encountered as isolated finding or as part of syndromic diseases. We report a case of a 40-year- old female presenting with low back pain and sciatica due to ‘butterfly’ dysplasia of the first sacral vertebra. This novel case includes posterolateral displacement of the completely separated hemivertebrae, causing left lateral recess stenosis and compression of S1 nerve root. Additionally, we conducted a short review of the literature. Few cases are reported in literature. Only one refers to a sacral vertebra. There is no previous case of a butterfly vertebra that accounts for narrowing of the lateral recess and associated radiculopath

Anatomy and clinical significance of sacral variations: a systematic review

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 recognized deviations of the sacrum structure, while highlighting the aspects of their clinical significance

Morphological and morphometric features of sacral hiatus and its clinical significance in caudal epidural anesthesia

Background: Caudal epidural block (CEB) failure or complications are not unheard even among experienced anesthesiologists and are usually due to sacral hiatus (SH) anatomy variations. The aim of the present study is to observe, record and analyze important anatomical features of SH and correlate them with potential CEB limitations. Materials and methods: The SH of 155 complete and undamaged Greek adult dry sacra of known sex were included in the study. Three non-metric (shape of SH and location of hiatal apex and base in relation to level of sacral/coccygeal vertebra) and five metric parameters (height of the SH, transverse width of the SH at the base, anteroposterior diameter of the SH at the level of its apex and the distance from the sacral apex and base to the upper border of S2 foramina) were evaluated. Results: Inverted U (34.83%) and inverted V (26.45%) were the commonest shapes. Hiatal apex and base were most commonly related to the level of S4 (78.70%) and S5 vertebra (89.03%), respectively. Mean height, depth and intercornual distance were 19.05±8.65 mm, 5.39±1.84 mm and 12.41±3.16 mm, respectively, whereas mean distance between the upper border of S2 foramen and the apex and base of the sacral hiatus were 46.34 mm and 63.48mm, respectively. Anatomical variations of sacral hiatus that might be responsible for CEB failure, such as elongated SH, absence of SH, complete dorsal wall agenesis of sacral canal and narrowing ( < 3 mm) at the apex of SH were found in 17.43% of sacra (male 10.94% and female 25.22%).  Conclusions: This study suggests a potential risk of failure of CEB in Greek patients, especially in females, which should be kept in mind while giving caudal epidural anesthesia

Investigating the phenomenon of overkill in Greece: A forensic psychiatric autopsy study between 2005 and 2020

The purpose of this study was to investigate overkill in the Greek population from a criminological and victimological point of view and explore possible correlations of the phenomenon with socio-cultural or psychiatric factors. Overall, 158 autopsies of overkill victims were identified throughout the 15-year records of the national forensic laboratories throughout the northern Greek mainland. The pattern that has emerged from the statistical results of the present study on the victims of overkill within the Greek borders was generally in line with global statistics on homicide victims, but also presented differences. The phenomenon correlated more with homicides in the context of mental disorders (within schizophrenia spectrum), other crimes (such as burglary) as well as domestic violence. Overall, males outnumbered females both as victims (approximately threefold) and as perpetrators in overkill homicide cases, but regarding domestic violence, the sad majority of overkill victims stood for females murdered with excessive violence by male relatives. Close female relatives (especially mothers and grandmothers) were also victimized by psychiatrically ill offenders. Female perpetrators tended to attack male individuals with whom they shared a relationship (intimate partners). An important finding was the fact that less than half the offenders’ population with major mental disorders were diagnosed at the time of the offense. Overkill victims were found, on average, to be older than average homicide victims, being probably associated with the entailed difference in the physical strength ratio between the victim and the perpetrator. © 2021 Elsevier Ltd and Faculty of Forensic and Legal Medicin

Self-immolation Suicide in Greece: A Forensic Psychiatric Autopsy Study between 2011 and 2019

Self-immolation is a rare suicide method in the developed countries of the western world (0.06–1%); however, it has relatively higher prevalence rates in the developing countries of Asia and Africa (6–57%). The present study aims to examine self-immolation suicides within the Greek mainland (Attiki, Thrace, and Peloponnese) over a period of 9 years (2011–2019) in order to investigate the phenomenon in the Greek population forensically, identify the characteristics and motivations of suicide victims, explore its associations to socio-cultural or psychiatric factors, and describe a fatal case of suicide by self-immolation that was partially recorded on camera. The medical files (autopsy reports) of cases performed at the Departments of Forensic Medicine of the National and Kapodistrian University of Athens, Democritus University of Thrace, and the Forensic Service of Messinia—Peloponnese were retrospectively examined yielding 19 cases of suicides by self-immolation. A 3.7% prevalence of suicide by self-immolation among suicide fatalities within the Greek population was estimated. A distinctive feature of the Greek population regarding self-immolation was disclosed that it is being practiced predominantly by the elderly (mean age 2–3.5 decades higher than other countries). The phenomenon correlated strongly with poorly controlled mental disorders (mostly affective and adjustment disorders). Unlike other countries, there was no significant association with domestic or sexual violence, social or political protest, or religious issues. Therefore, the suicide victims preferred secluded or private outdoor locations (not public). Findings deriving from the examined variables localize Greek population culturally between the Western European and Asian African countries, but with its own idiosyncrasies. © 2020 American Academy of Forensic Science
