Título:	Accessory mandibular foramina and bifid mandibular canals - an anatomical study
Fuente:	Eur. j. anat;23(4):261-266, jul. 2019. ilus, tab.
Idioma:	en.
Resumen:	Bifid mandibular canals associated with accessory mandibular foramina are claimed to pose complications in oral surgery and allied procedures resulting in paraesthesia and haemorrhage, due to injury to the divisions of inferior alveolar nerves and vessels passing through them. Sometimes these nerves escape the effect of anaesthetics leading to difficult inferior alveolar nerve block. These variant canals serve as a source of spread of cancer from cortical to cancellous part of the mandible. The current descriptive study included thirty intact, dry, adult human mandibles. They were examined macroscopically to note the presence of accessory mandibular foramina and the accessory mandibular canals arising from them. These aberrant canals were probed and their length was noted. The probed mandibles were X-rayed to observe the course of these canals. The location of the foramina was determined from nearby anatomical landmarks.Six mandibles (20%) showed accessory mandibular foramina. The length of the accessory mandibular canals originating from the accessory mandibular foramina was found to vary from 0.9 cm to 4.5 cm. On X-ray films, the variant canals were noted to proceed towards third molar or towards the angle of mandible. Some of these canals merged with the main mandibular canal. The findings of the study will be helpful in oral surgery, radiology and cancer therapy No disponible

Título:	16 Sesamoid bones in the hands of healthy patient: case report
Fuente:	Eur. j. anat;24(6):523-526, nov. 2020. ilus.
Idioma:	en.
Resumen:	The sesamoid bones are round or oval bones that are located within tendons, and most theories consider that sesamoid bones in humans develop in response to local mechanical stress on a joint. Although their function is not well understood, it is known that they act as a pulley modifying the angle of movement and their insertion. They are mostly inconsistent, which is why they tend to be supernumerary and are located in different parts of the body at the level of the extremities, with the patella being the largest, most constant and best known. The prevalence and distribution of sesamoids in the hand varies between different populations and sex. They are rarely reported since they are only considered anatomical variants, but clinically there are several pathologies related to the sesamoid bones in the hand such as: trauma, degenerative disorders, giant cell tumors, osteochondroma, avascular necrosis, tendon ruptures, genetic disorders and attention should be paid in patients with acromegaly where their length is increased. In this article, we report a total of 16 sesamoid bones, symmetrically distributed 8 ineach hand of a healthy individual treated in the Plastic Surgery Department of the "Dr. Rubén Leñero" Hospital in Mexico City. In the literature reviewed, we did not find a report with the presence of so many sesamoid bones in both hands, which motivated us to report it No disponible

Título:	Embryological basis of coarctation in cervical aortic arch: Ductus caroticus anomaly
Fuente:	Eur. j. anat;24(6):519-521, nov. 2020. ilus.
Idioma:	en.
Resumen:	Coarctation of the cervical aortic arch (CAA), though rare, is a clinical entity of embryological significance. Based on Rathke's aortic arch diagrams and Edward's concept of functioning double aortic arch, we are postulating that the coarctation in a CAA occurs due to partial involution of the dorsal aorta developed from the "ductus caroticus". Hence coarctation in CAA should be classified as a "clinically significant aortic arch anomaly of ductus caroticus origin". Conversely, location of coarctation in CAA substantiates the theory that embryogenesis of CAA is due to aortic arch development from the third or second branchial arch vessel, rather than the usual fourth arch vessel No disponible

Título:	A left vertebral artery arising from the aortic arch: a cadaveric study
Fuente:	Eur. j. anat;24(6):513-517, nov. 2020. tab, ilus.
Idioma:	en.
Resumen:	Variations in the major arteries and their branches of the thoracic region have been well described with variations of the aortic arch, pulmonary trunk, common carotid arteries and vertebral arteries being among the most common in the thoracic region. During routine dissection of the thoracic and neck regions, the left vertebral artery in a 58-year-old female cadaver was found to arise from the arch of the aorta between the left common carotid and the left subclavian arteries. The left vertebral artery was traced along its course and was observed to enter the transverse foramen of the fifth cervical vertebral body. With such variation, the findings can influence predisposition to diseases, symptomatology, clinical examination, investigation and patient management, including operative surgery No disponible

Título:	Direct emergence of the conus artery from an independent ostium. A cadaveric study on a Spanish sample
Fuente:	Eur. j. anat;24(6):501-505, nov. 2020. tab.
Idioma:	en.
Resumen:	The main purpose of this study was to evaluate the frequency with which the conus artery originates from an independent ostium in the right aortic sinus. Twenty-five adult hearts (3 females, 5 males and 17 unknown sex), from the body donation program of the University of Girona, were analysed. After intravascular injection of natural coloured latex in the coronary ostia, the origin of the conus artery and its distribution pattern were analysed by microdissection. Three of the 25 hearts analysed (12.0%) displayed the direct emergence of the conus artery from a discrete ostium in the right aortic sinus: in two specimens (8%) showing a single ostium for the independent conus artery, and in one heart (4%) two ostia for two independent conus arteries. In all cases, the independent conus arteries were shorter than the coronary artery and extended up to the anterior wall of the right ventricle, coinciding with the observations of previous authors. The independent conus artery may be an important source of collateral blood flow to the infundibulum. It may be an important source of apex and interventricular septum collateral irrigation. To ascertain the origin of the conus artery and its distribution is clinically important, particularly in obstructions of the anterior interventricular artery. The independent conus artery's collateral perfusion can both obscure the detection of any ischaemic modification in the apex and septum regions, and serve as a therapeutic source. Consequently, interpretations of the coronary occlusion clinical test should take this vascular channel into account No disponible

Título:	The architecture of the 6-month-old gastrocnemius: a 3D volumetric study
Fuente:	Eur. j. anat;24(6):491-499, nov. 2020. tab, ilus.
Idioma:	en.
Resumen:	Gastrocnemius is essential in normal gait, contributing to the control of ankle plantar flexion and knee flexion. However, there is a paucity of literature on the architecture of the infant gastrocnemius muscle prior to the onset of weight-bearing and gait. This study investigates the three-dimensional (3D) musculoaponeurotic architecture of the gastrocnemius in a six-month-old infant. One six-month-old cadaver was used in this study (The University of Toronto Health Sciences Research Ethics Board, #32679, and The University of Auckland Human Participants Ethics Committee, #016164). Medial (MG) and lateral (LG) heads of the gastrocnemius were serially dissected and a Microscribe G2X(TM) digitizer used to digitize fiber bundles, aponeuroses and tendons. Data were then exported to Autodesk(R) Maya(R) to create 3D models. Custom software quantified architectural parameters, including fiber bundle length, pennation angle, physiological cross-sectional area, and muscle volume. The intramuscular architecture was assessed to determine whether musculoapo-neurotic partitions were present. Muscle volume was <1cm3 for both MG and LG. Three architectural partitions, proximal, middle, and distal, were identified for both MG and LG. Notably, the proximal partitions of both MG and LG had mean fiber bundle length at 2.21 ± 0.41 cm and 2.22 ± 0.27 cm, significantly greater (p < 0.05) than the middle and the distal partitions. The results of this study suggest that both MG and LG have architectural partitions before the commencement of gait. Further longitudinal studies with larger sample sizes are needed to confirm the presence of these architectural partitions, as well as to investigate their growth across the developmental spectrum No disponible

Título:	Evaluation of gubernacular tract with cone beam computed tomography in impacted supernumerary teeth
Fuente:	Eur. j. anat;24(6):485-490, nov. 2020. tab, ilus.
Idioma:	en.
Resumen:	The gubernacular canal or gubernacular tract is filled by the gubernacular cord, which includes fibrous connective tissue containing peripheral nerves, blood and lymphatic ducts besides the epithelial cells from the fragmented dental laminae, including epithelial growth factor. The purpose of this study was to evaluate the gubernacular tract in unerupted supernumerary teeth by cone beam computed tomography. Sixty-four unerupted supernumerary teeth were selected from 44 patients (21 females, 23 males, 12-68 years). Gubernacular tract characteristics were evaluated in five different groups: No alteration, bending of gubernacular tract, contraction of gubernacular tract, obliterations of gubernacular tract, difference between erupted direction. Unerupted supernumerary teeth were classified according to their position. The presence and characteristics of the gubernacular tract in the supernumerary teeth were evaluated by cone beam computed tomography. In our study, the frequency of the gubernacular tract was found to be 31.7%. There was no significant difference between the presence of gubernacular tract and gender, age and gubernacular tract characteristics. It was found that gubernacular tract characteristics did not change according to gender, quadrant, age and unerupted positions. Cone beam computed tomography is an efficient method for the evaluation of the gubernacular tract in unerupted supernumerary teeth. Conducting these studies in larger populations will provide more detailed information about the prognosis of impacted supernumerary teeth No disponible

Título:	The altered profile of a donated cadaver population: challenges for teaching and research?
Fuente:	Eur. j. anat;24(6):475-483, nov. 2020. tab, graf.
Idioma:	en.
Resumen:	Efforts by anatomists over the recent past, have converted the cadaver population in a South African institution from a predominantly unclaimed population into one purely derived from donors. Concurrent with this transformation were noticeable changes in cadaver demographics, which raised concerns for aspects of teaching and research. The aim of this study was therefore to explore the effects of donation on the demographics and anatomical integrity of the School's 2017 cadaver population. The provenance, ancestry, sex and age of 74 cadavers were investigated. Dissected cadavers were studied to ascertain the general condition of their anatomy. Variations in tissue integrity, morphology and overt pathologies were surveyed. Cadavers represented only one population group with slightly more females (54%). The majority of the cohort (62%) was aged between 71 and 90 years. With regards to anatomical integrity, 60% of the cadavers presented with adhering fascia, but no significant differences in the quantity of fat were found across the sample. High levels of muscle tearing and atrophy (76%) occurred and variations in visceral anatomy were noted. Various surgical interventions and overt pathologies were also observed. The donated cadaver population differed from previous unclaimed cadaver populations in that they consisted of only White, older individuals. Variations, surgical interventions and pathologies offer staff in anatomy an opportunity to engage with more clinically-oriented teaching, as well as introducing students to the discipline of gerontology No disponible

Título:	Corpus callosum morphology of healthy children: a structural magnetic resonance imaging study from Turkey
Fuente:	Eur. j. anat;24(6):467-473, nov. 2020. tab, graf, ilus.
Idioma:	en.
Resumen:	Morphological measurement of corpus callosum (CC) in magnetic resonance imaging studies has an important value for clinical decision-making during the period of childhood. Although there is evidence for differences in brain morphology in terms of socioeconomic disparities, there is no research specifically on CC morphology from any low-and middle-income countries. This study aims to report structural measurements and area of CC of healthy children from Turkey, a middle-income country, and find out whether the CC morphology differs between male and female children in different age groups. Healthy children aged 6-18 years were recruited retrospectively and their CC antero-posterior (AP) length, genu, body and splenium width (GW, BW, SW) and CC midsagittal area were measured from magnetic resonance imaging studies. Independent sample t-test was used to compare CC measurements of the sex and age groups. Pearson correlation test was used to determine linear correlations between age and CC parameters. The sample consisted of 200 healthy children; at least 5 female and 5 male children for each age; 103 (51.5%) females, 97 (45.5%) males. There was a positive correlation between the age and CC AP length (r=0.248, p < 0.001) and SW (r=0.325, p < 0.001) as well as midsagittal area (r=0.191, p < 0.007). The CC AP length, GW, BW, SW and area were not different statistically between sex groups.This study is the first report providing age and sex-related morphological measurements of CC of healthy children in Turkey. The findings may be helpful for clinicians and researchers from Turkey as well as other low-and middle-income countries No disponible
