How to simplify the approach to the supra-aortic trunks.
Abstract Carotid artery stenting (CAS) represents a valid alternative to carotid endarterectomy (CEA). Possible embolization during the approach and the cannulation of the supra-aortic arterial trunks remains an important obstacle to CAS. This risk is increased in elderly patients and complex anatomies. In order to achieve satisfactory technical and clinical outcomes, a thorough understanding of the patients' individual anatomy of the arch and the access vessels is essential. The cannulation of the common carotid artery represents the key maneuver for the entire CAS procedure. This review article will present the c...

Carotid artery stenting with filters.
Abstract Filters are a valuable aid for safe carotid artery stenting, but require good knowledge of their function, and their shortcomings. Filters capture visible particles in 5-20% and microscopically in about 70% of the cases. Transcranial Doppler ultrasound and diffusion weighted MRI investigations have shown that particles are released during filter placement and also during the next steps of the procedure. They can pass through the filter pores when they are small enough and through unprotected areas when the filter is not completely apposed to the arterial wall. Therefore, they do not reliably prevent transi...

Modeling Secondary Messenger Pathways in Neurovascular Coupling.
We present a model of intracellular calcium dynamics in an astrocyte (glial cell) and show that stable oscillatory behaviour is possible under certain conditions. We then couple this to a novel model for the relationship between calcium concentration and the production of vasoactive secondary messengers through a fatty-acid intermediate. The two secondary messengers modelled are epoxyeicosatrienoic and 20-hydroxyeicosatetraenoic acids (EET and 20-HETE, respectively). These secondary messengers are produced on different time scales, and we show how this supports the observation that the vasculature dilates rapidly in respon...

Humphrey Ridley (1653‐1708): Forgotten neuroanatomist and neurophysiologist
Humphrey Ridley is a little known character in the history of anatomy and physiology. Born in 1653, Ridley was a physician and anatomist who followed the research done by Willis, Vieussens, and Galen. Outside of a cursory knowledge of his birth and death, readers have only two remnants of his contributions to science: The Anatomy of the Brain, containing its Mechanism and Physiology and Observationes Quaedam Medico‐Practicae et Physiologicae de Asthmate et Hydrophobia. The former text was the first book in the English language written on the human brain. Ridley's studies using cadavers executed by hanging provided him wi...

Transverse cervical nerve: Implications for dental anesthesia
The inferior alveolar nerve block (IANB) has the highest failure incidence of any dental anesthetic technique. Many authors have outlined potential reasons for these failures in permanent lower molars, including accessory innervations from the mylohyoid and mental foramen. However, the potential accessory innervation of posterior mandibular teeth from the transverse cervical nerve (TCN), a branch of ventral rami from the C2–C3 spinal nerves from the cervical plexus (CP), has been difficult to assess as a result of the small size and thickness of the mandibular accessory foramina and nerve branches, as well as due to the ...

Measuring distortion of skeletal elements in Lodox Scatscan‐generated images
Due to a scarcity of available skeletal material, anthropologists and other practitioners face difficulties with either the creation or validation of techniques used to estimate a biological profile in subadults. To address this problem, radiographic images of living individuals are often used in lieu of dry skeletal elements. However, radiographic images suffer from distortion. Some problems with metric analyses when using radiographic images may be addressed with the Lodox Statscan, an X‐ray machine that claims to produce minimal distortion along the scan‐axis due to a linear slot‐scanning design. The purpose of th...

Comparison of musculoskeletal anatomic relationships, determined by magnetic resonance imaging, in postpubertal female patients with and without classic bladder exstrophy
Conclusions In postpubertal females with bladder exstrophy, significant deviations from normal pelvimetry exist, including posterior location of the majority of the levator ani muscle, a wider ileococcygeous angle and a wider symphyseal diastasis. These differences are similar to those described in previous comparisons of younger children with bladder exstrophy and control children.

Functional significance of synaptic terminal size in glutamatergic sensory pathways in thalamus and cortex.
Abstract Glutamatergic pathways are a major information carrying and processing network of inputs in the brain. There is considerable evidence suggesting that glutamatergic pathways do not represent a homogenous group and that they can be segregated into at least two broad categories. Class 1 glutamatergic inputs, which are suggested to be the main information carriers, are characterized by a number of unique synaptic and anatomical features, such as the large synaptic boutons with which they often terminate. On the other hand, Class 2 inputs, which are thought to play a modulatory role, are associated, amongst oth...

Extraordinary branching pattern of the aortic arch
Abstract A CT‐scan of a 75‐year‐old patient showed an aneurysm of the descending aorta with a maximum diameter of 4.8 cm involving the left subclavian artery. Due to the fact that the patient had several comorbidities including a severe chronic obstructive pulmonary disease he was treated only conservatively. However, there were several interesting findings on the CT‐scan: the branching pattern of the aortic arch revealed a left carotid artery arising as first side branch of the distal part of the ascending aorta. This vessel crosses the midline right in front of the trachea. Apart from that the patient did not hav...

Variants of the supplying vessels of the vascularized iliac bone graft and their relationship to important surgical landmarks
Abstract The iliac bone crest is one of the most valuable regions for harvesting bone grafts, both vascularized and nonvascularized. Since the first commendable description of this region as a possible source for vascularized bone flaps by Taylor, little relevant information concerning the variations of the deep circumflex iliac vessels and their relationship to the neighboring structures has been published. The purpose of the current study was to examine this region clinically and anatomically, taking into consideration the former description by Taylor. We gathered all our findings on 216 iliac regions and proposed a new ...

Dermatan 4-O-sulfotransferase1 ablation accelerates peripheral nerve regeneration.
Abstract Chondroitin sulfate (CS) and dermatan sulfate (DS) proteoglycans are major components of the extracellular matrix implicated in neural development, plasticity and regeneration. While it is accepted that CS are major inhibitors of neural regeneration, the contributions of DS to regeneration have not been assessed. To enable a novel approach in studies on DS versus CS roles during development and regeneration, we generated a mouse deficient in the dermatan 4-O-sulfotransferase1 (Chst14(-/-)), a key enzyme in the synthesis of iduronic acid-containing modules found in DS but not CS. In wild-type mice, Chst14 i...

Aortic valve replacement via right anterolateral thoracotomy in the case of a patient with extreme mediastinal right-shift following pneumonectomy
We report on the case of a 68-year-old male patient with the history of right pneumonectomy due to bronchial carcinoma, who was referred for aortic valve replacement due to severe calcified aortic stenosis. Pre-operative chest X-ray and computed tomography (CT) revealed an unusually pronounced mediastinal shift to the right. Despite this unusual anatomy, we decided to perform surgery using the right anterolateral thoracotomy following thorough pre-operative planning using 3D-volume rendering of the CT data-set. This approach yielded excellent exposure of the aortic root and the ascending aorta, respectively. Following an u...

Does senescence affect lymph node number and morphology? A systematic review
ConclusionIn this first systematic review to examine changes in lymph nodes with senescence, evidence was accrued to suggest a decline in lymph node number and morphological degeneration in older age groups. These changes might adversely affect immune function and the prognosis of infections and selected cancers in the elderly. Further research is required to confirm these morphological changes and to explore their potential immunological and functional effects.

MRI of ovarian masses
Abstract MRI provides exquisite views of the pelvic anatomy through its high spatial resolution and tissue contrast, and as such plays a key role in the work up of ovarian lesions, identifying features that distinguish benign and malignant lesions. In the case of primary tumors it enables local staging and detection of metastatic disease to help guide management options such as complex surgery or the consideration of neoadjuvant chemotherapy. Functional MRI techniques such as diffusion‐weighted MRI (DW‐MRI), dynamic contrast‐enhanced MRI (DCE‐MRI) and tumor‐selective molecular imaging are currently being evaluate...

Anatomy of a blastocyst: Cell behaviors driving cell fate choice and morphogenesis in the early mouse embryo
ABSTRACT The preimplantation period of mouse early embryonic development is devoted to the specification of two extra‐embryonic tissues and their spatial segregation from the pluripotent epiblast. During this period two cell fate decisions are made while cells gradually lose their totipotency. The first fate decision involves the segregation of the extra‐embryonic trophectoderm (TE) lineage from the inner cell mass (ICM); the second occurs within the ICM and involves the segregation of the extra‐embryonic primitive endoderm (PrE) lineage from the pluripotent epiblast (EPI) lineage, which eventually gives rise to the ...

The role of the acetabular labrum in hip dysplasia.
Abstract A periacetabular osteotomy (PAO) is the preferred joint preserving treatment for young adults with symptomatic hip dysplasia and no osteoarthritis. In symptomatic dysplasia of the hip, there is labral pathology in up to 90% of cases. However, no consensus exists as to whether a labral tear should be treated before the periacetabular osteotomy (PAO), treated simultaneously with the PAO, or left alone and only treated if symptoms persist after the PAO.

Conclusion: Familiarity of the vasculature of the internal pelvis is of utmost importance for the surgeon when considering operative fixation of the anterior SI joint. We were able to identify the relation of the nutrient artery to the anatomic landmarks of the internal pelvis and to define the “at risk area” for the nutrient artery. We believe increased understanding of the anatomy of the nutrient artery will aid in the avoidance of vascular complications during internal fixation of the anterior SI joint.

Late embryos and bony skull development in Bothropoides jararaca (Serpentes, Viperidae).
Abstract In recent years, developmental anatomy received increasing interest as a potential new source for phylogenetic research. For skeletal development, studies mainly rely on the first appearance of ossification centers. However, informative events occur during the whole course of skeletogenesis; interactions between external and internal development occur and morphometric changes take place - all of which present potential sources for phylogenetic analyses. Therefore, the Standard Event System (SES) was used to traceably describe the external development of the snake species Bothropoides jararaca and external ...

Influence of edentulism on human orbit and zygomatic arch shape
Abstract Edentulism, or tooth loss, seriously alters the appearance of the lower facial skeleton. The aim of this study was to determine if complete maxillary edentulism also impacts the curvature shape of the orbits and zygomatic arches in elderly adults. The study was conducted on 80 crania comprising two cross‐sectional populations of elderly African‐ and European‐Americans (60–80 years old). Forty of the crania possessed intact dentition; the remaining 40 exhibited complete edentulism with tooth socket resorption. Three‐dimensional semilandmarks representing the curvature of the orbits and zygomatic arches we...

One is the loneliest number: A review of the ganglion impar and its relation to pelvic pain syndromes
Abstract The ganglion impar is often overlooked as a component of the sympathetic nervous system. Despite its obscurity, this ganglion provides a pathway for neurons by accommodating postganglionic sympathetics, visceral afferents, and somatic fibers traveling to and from the pelvis. Its classic anatomic location as described in the 1720's held up until recently, with the current literature now revealing a great deal of anatomical variability. This variation becomes important when the ganglion impar is used as a treatment target for patients with chronic pelvic pain – its primary clinical implication. The aim of this rev...
