The authors present an example from the expert practice demonstrating the influence of such factors as the properties of the ammunition fired from a weapon (including its weight, size, shape, and speed) as well as the anatomical features of the body tissues being affected on the mechanism of formation of a gunshot wound in the human body. The investigation of the suicide of subject P. has demonstrated the penetrating bullet wound of the neck and the head. The entrance wound was located at the anterior neck surface and the exit one in the left half of the occipital region...

Originally discovered in elasmobranchs by Fritsh in 1878, the nervus terminalis has been found in virtually all species, including humans. After more than one-century debate on its nomenclature, it is nowadays recognized as cranial pair zero. The nerve mostly originates in the olfactory placode, although neural crest contribution has been also proposed. Developmentally, the nervus terminalis is clearly observed in human embryos; subsequently, during the fetal period loses some of its ganglion cells, and it is less recognizable in adults...

Transcranial focused ultrasound (tFUS) is emerging as a non-invasive brain stimulation modality. Complicated interactions between acoustic pressure waves and osseous tissue introduce many challenges in the accurate targeting of an acoustic focus through the cranium. Image-guidance accompanied by a numerical simulation is desired to predict the intracranial acoustic propagation through the skull; however, such simulations typically demand sophisticated computation, which warrants an expedited processing method to provide on-site feedback for the user in guiding the acoustic focus to a particular brain region...

PURPOSE: The authors hypothesized that the risks of optic canal injury in down-fracturing after Le Fort 3 osteotomy vary depending on the separation patterns of the orbital walls. This study verifies this hypothesis using biomechanical simulation. METHODS: Ten finite-element skull models were produced using computer tomography data from ten persons. These models were modified to simulate Le Fort 3 osteotomy models by removing junctions between the neurocranium and facial cranium...

INTRODUCTION: Intracranial malignant peripheral nerve sheath tumor (MPNST) is exceedingly rare. Previously reported cases of intracranial MPNST have been associated with development within a prominent cranial nerve. METHODS: This is the first report of an MPNST with both nerve sheath and vascular phenotype that follows the neurovascular bundle, without arising in a major cranial nerve or in the setting of neurofibromatosis type 1 (NF1). RESULTS: The patient is a 14-year-old boy with a history of worsening headaches for the past several months, left-sided hearing loss, nausea, vomiting, and vertigo...

BACKGROUND: The experimental approach to the evolution and development of the vertebrate skeleton has to a large extent relied on "direct-developing" amniote model organisms, such as the mouse and the chicken. These organisms can however only be partially informative where it concerns secondarily lost features or anatomical novelties not present in their lineages. The widely used anamniotes Xenopus and zebrafish are "indirect-developing" organisms that proceed through an extended time as free-living larvae, before adopting many aspects of their adult morphology, complicating experiments at these stages, and increasing the risk for lethal pleiotropic effects using genetic strategies...

Modern humans have smaller faces relative to Middle and Late Pleistocene members of the genus Homo. While facial reduction and differences in shape have been shown to increase biting efficiency in Homo sapiens relative to these hominins, facial size reduction has also been said to decrease our ability to resist masticatory loads. This study compares crania of Homo heidelbergensis and H. sapiens with respect to mechanical advantages of masticatory muscles, force production efficiency, strains experienced by the cranium and modes of deformation during simulated biting...

OBJECTIVES: High-resolution imaging of fossils with X-ray computed microtomography (μCT) has become a very powerful tool in paleontological research. However, fossilized bone, embedding matrix, and dental tissues do not always provide a distinct structural signal with X-rays. We demonstrate the benefits of high-resolution neutron radiation in three different specimens showing problematic contrasts with X-ray μCT. MATERIALS AND METHODS: We compare neutron with X-ray μCT scans of fossils from two Miocene catarrhines from the Vallès-Penedès Basin: the cranium (IPS58443...

Research into photobiomodulation reveals beneficial effects of light therapy for a rapidly expanding list of medical conditions and illnesses. Although it has become more widely accepted by the mainstream medicine, the effects and mechanisms of action appear to be poorly understood. The therapeutic benefits of photobiomodulation using low-energy red lasers extend far beyond superficial applications, with a well-described physics allowing an understanding of how red lasers of certain optimum intensities may cross the cranium...

BACKGROUND: As far as our literature searches showed us, morphological characteristics of cranium such as sutures, sutural bones and fontanelles had been examined from the skulls in the museums and dry specimens until now. As a modern method, 3D virtual remodeling of cranial bones by using MDCT-CTA can display in vivo morphological characteristics. In our study, we aimed to determine the presence and incidence of these morphological characteristics that can be clinically significant in our population, by using radiologic methods...

Studying secular changes on human skulls is a central issue in anthropological research, which is however insufficiently investigated for modern German populations. With our study, we focus on morphological cranial variations within Germans during the nineteenth and twentieth centuries. To study this, we recorded different facial landmarks from a cohort study of about 540 German individuals of different age and sex by calculating their cranial size, shape dimensions, and cranial module and cranial capacity to get information about variations occurring during the decades...

Over a decade ago, the Atacama humanoid skeleton (Ata) was discovered in the Atacama region of Chile. The Ata specimen carried a strange phenotype-6-in stature, fewer than expected ribs, elongated cranium, and accelerated bone age-leading to speculation that this was a preserved nonhuman primate, human fetus harboring genetic mutations, or even an extraterrestrial. We previously reported that it was human by DNA analysis with an estimated bone age of about 6-8 yr at the time of demise. To determine the possible genetic drivers of the observed morphology, DNA from the specimen was subjected to whole-genome sequencing using the Illumina HiSeq platform with an average 11...

Primary blast traumatic brain injury (bTBI) accounts for a significant proportion of wartime trauma. Previous studies have demonstrated direct brain injury by blast waves, but the effect of the location of the blast epicenter on the skull with regard to brain injury remains poorly characterized. In order to investigate the role of the blast epicenter location, we modified a previously established rodent model of cranium-only bTBI to evaluate two specific blast foci: a rostrally focused blast centered on the Bregma (B-bTBI), which excluded the foramen magnum region, and a caudally focused blast centered on the occipital crest, which included the Foramen Magnum region (FM-bTBI)...

BACKGROUND: The management of fronto-orbital fibrous dysplasia involves total excision of the dysplastic bone and bone reconstruction using implants. Custom-made implants are used to achieve good contouring. However, the remnant defect after excising the lesion often does not match the implant. METHODS: To design the craniotomy line, a template was prepared by preoperative computed surgical simulation. The template was overlaid on the preoperative cranium, such that its inner surface fits exactly with the cranial surface...

Many fossil specimens exhibit deformations caused by taphonomic processes. Due to these deformations, even important specimens have to be excluded from morphometric analyses, impoverishing an already poor paleontological record. Techniques to retrodeform and virtually restore damaged (i.e. deformed) specimens are available, but these methods genenerally imply the use of a sparse set of bilateral landmarks, ignoring the fact that the distribution and amount of control points directly affects the result of the retrodeformation...

Craniofacial Actinomyces osteomyelitis progression is rare, as patients are soon treated. A 56-year-old male smoker presented with sinusitis and was managed medically. This patient failed to follow up and presented 1 year later with erosive bony disease. He was managed medically and surgically; however, his disease evolved to include his midface, skull base, and cranium. He underwent staged debridement and free tissue reconstruction. His disease is controlled but not cured. The literature includes case reports and small series describing limited disease treated successfully with surgical and medical management...

Craniopagus twins are conjoined twins fused at the cranium. This is the rarest anomaly seen in conjoined twins and craniopagus twins account for 2- 6% of conjoined twins. Conjoined twins are also extremely rare, with the anomaly seen in about 10-20 subjects per billion births. A female preponderance has been noted. Craniopagus twins can be classified into complete or partial, depending on whether or not they have shared dural venous sinuses. They can be further classified into angular or total depending on the alignment of the inter-twin longitudinal axis...

To date, the only instance of tick-borne encephalitis (TBE) in Japan was reported from the southern part of Hokkaido Island in 1993; no other cases have been reported since then. We herein report the first case of TBE reported in the central part of Hokkaido Island, and describe the fatal clinical course of a patient who presented with meningoencephalomyelitis, which partly involved the nerve root. Magnetic resonance imaging (MRI) of the patient's cranium and spine revealed characteristic central nervous system involvement...
