[Forehead injections: Anatomy, technics, products]. / Les injections du front : anatomie, techniques, produits.

Knowledge of anatomy not only allows optimal treatment and therefore full satisfaction of our patients, but is also fundamental in the prevention of complications. A thorough understanding of aging allows for effective treatments, as most patients demand a natural result, removing the inevitable signs of aging, which can only be understood by considering their aging. Facial aging is a natural but complex multifactorial process, particularly for the forehead. In this article, we will focus on botulinum toxin as well as fillers in aging.

[Anatomy of the frontal region]. / Anatomie de la région frontale.

The forehead is an anatomic region located between the frontal hairline cranially, the eyebrow and the glabella caudally, and the anterior border of the temporal fossa laterally on both sides. Its vertical situation, due to the telencephalon growth, is specific of the human species. From surface to deep planes, the skin and sub-cutaneous fat pads are described first. The muscular plane is constituted of the frontal muscles elevators of the forehead and the eyebrow, and the depressors which are the procerus and orbicularis oculi muscles superficially, the depressor supercilii muscle, and the corrugator supercilii in a deep plane. The galea aponeurotica, located deep to the frontal muscles, is a fibrous lamina on which the muscles of the skull insert. There is a sexual dimorphism of the frontal bone. The male forehead has extensive supraorbital bossing, and above this there is often a flat area, in teh femalethe supraorbital bossing is often nonexistent and above, there is a continous mild curvature. Blood supply to the forehead is given by an anterior pedicle constituted by the supraorbital and supratrochlear vessels and a lateral pedicle made of the anterior branches from the superficial temporal vessels. The sensory innervation of the forehead is given by the ophtalmic nerve which divides in frontal, nasociliar and lacrymal nerves. The motor innervation is given by the temporal ramus of the facial nerve which passes laterally to the zygomatic arch, and gives the innervation of the frontal, corrugator supercilii and procerus muscles.

[A thyroid pathology: The great simulator]. / Une pathologie thyroïdienne : la grande simulatrice.

INTRODUCTION: Tuberculosis remains a major public health problem in developing countries. Thyroid localization is very rare, and often the cause of misdiagnosis. Pathological anatomy plays an important role in the diagnosis of certainty. The authors report a case of primary thyroid tuberculosis in a 22-year-old patient. We highlight the epidemiological particularities of this case, and discuss diagnostic methods and the contribution of pathological anatomy. OBSERVATION: A 22 year-old male patient, with no reported pathological history, was seen in the clinic for the management of an isolated anterior cervical swelling that had been evolving for two months. Clinical examination revealed only a small thyroid nodule, with no inflammatory or vascular features. Biological tests were unremarkable. Ultrasound revealed a 2.4cm hypoechoic, homogeneous, poorly vascularized tissue mass in the left lobe, classified as EU-TIRADS 3. Fine needle aspiration with cytopathological study revealed a necrotizing granulomatous lesion suggestive of tuberculosis. A lobo-isthmectomy was performed, and histopathology revealed thyroid parenchyma destroyed by tubercular granulomas. The postoperative course was straightforward, with an exeat on postoperative day 6. Anti-tuberculosis treatment was instituted for 6 months. Three- and six-month follow-up examinations were unremarkable. The evolution was favorable, with recovery after treatment. CONCLUSION: Primary thyroid tuberculosis is rare. Cytology is important for orientation, and often helps to avoid misdiagnosis. The diagnosis should be considered in the presence of any thyroid mass in a patient from a tuberculosis-endemic region.

Gross and Applied Anatomy Pedagogical Approaches in Occupational Therapy Education: A Scoping Review.

Introduction. With technological advancements, anatomy teaching approaches in occupational therapy education have expanded. However, uncertainty remains regarding the approaches that best optimize academic and practice outcomes in student occupational therapists (OTs). Purpose. This scoping review mapped the pedagogical approaches used to teach musculoskeletal anatomy to student OTs. Methods. A scoping review was conducted, with a consultation exercise involving Canadian occupational therapy educators. Six databases were searched, with terms related to student OTs, anatomy, and education. Included articles were available in English, full text; featured empirical research of any study design and/or gray literature; featured a pedagogical approach used to teach anatomy; and targeted student OTs with the pedagogies. Results. Twenty-eight reports between 1978 and 2021 were included. Although technology-based pedagogies became more common with time, historically used pedagogies (e.g., lectures and labs) remained prominent and most common. Narrative synthesis regarding the effectiveness of anatomy pedagogical approaches identified five main factors: (a) anatomy competency; (b) teaching method diversity; (c) learner psychological considerations; (d) interprofessional education; and (e) optimal academic outcomes. Implications. This review demonstrates the importance of anatomy knowledge to occupational therapy education and practice. A diversity of pedagogical approaches, with and without technology, may foster better outcomes by addressing diverse learning needs.

Apprendre l'anatomie radiographique en présentiel ou en ligne ? Une étude randomisée contrôlée.

Résumé L'enseignement de l'anatomie repose sur diverses techniques: les cours, les dissections, les modèles 3D ou encore les supports en ligne. Ces derniers sont généralement considérés comme des moyens d'apprentissage complémentaires. Cette étude vise à comparer les performances des étudiants vétérinaires (N=83) en anatomie radiographique (radioanatomie) après un apprentissage en ligne ou conventionnel, et de voir dans quelle mesure ces méthodes sont interchangeables. Trois stratégies sont comparées : apprentissage en ligne exclusif, apprentissage en ligne avec des os de chevaux, apprentissage sur radiographies conventionnelles avec des os de chevaux. Les performances au test de rotation mentale et au test de connaissance en radioanatomie sont similaires entre les 3 groupes à la base, lors du test préliminaire. Après l'apprentissage (test final), les scores de rotation mentale et de radioanatomie augment significativement de 6.7/40 points (CI : 5.2­8.2; p < .001) et de 5.1/20 points (CI: 4.3­5.9; p< .001). Il n'y a pas de différence entre les groupes pour les scores de rotation mentale et de radioanatomie après l'apprentissage. Le score de rotation mentale est influencé par le genre, et significativement plus élevé chez les hommes que chez les femmes au test préliminaire (M= 23.0, SD = 8.8 vs. M= 16.5, SD= 6.9; p= .001) et au test final (M= 32.1, SD= 5.5 vs. M= 22.7, SD= 8.6; p< .001). Les performances en radioanatomie ne sont pas influencées par le genre. Ces résultats suggèrent que l'enseignement de la radioanatomie peut être réalisé en présentiel avec des radiographies conventionnelles ou en ligne. Cette interchangeabilité entre apprentissage en présentiel et en distanciel est intéressante au regard des impératifs liés aux crises sanitaires, et des besoins d'adaptation rapide en distanciel.

Anatomy of the biceps brachii osseous footprint: study of 100 radii and literature review.

Biceps brachii (BB) tendon rupture is frequent in young males and may require surgical repair. Non-anatomic reinsertion leads to loss of strength in supination. The main aim of the present study was to describe the anatomy of the osseous footprint of the distal BB tendon. The dimensions of the footprint of the distal BB insertion were analyzed in 100 dry cadaver radii, using MicroScribe 3D software. Insertion area, assimilated to an ellipse, was calculated from 4 points (medial, lateral, cranial and caudal) determining the two axes of the ellipse. Mean footprint length, width and area were 18 mm (range, 7-24 mm), 9 mm (range, 4-15 mm), and 129 mm2 (range, 46-266 mm²), respectively. Intra- and inter-observer correlation coefficients were satisfactory: κ = 0.75 and κ = 0.7, respectively. The present study reported BB footprint dimensions in 100 radii, providing a basis to guide surgical treatment of distal BB tendon rupture. Non-anatomical restoration of the BB tendon footprint leads to poorer clinical and biomechanical results; precise knowledge of the footprint is necessary for anatomical repair.

[Anatomic variations in the ethmoid sinus in patients undergoing dacryocystorhinostomy at the Hassan II de Fès Medical Center (study of 215 patients)]. / Variations anatomiques du sinus ethmoïdal des patients opérés de dacryocystorhinostomie au centre hospitalier Hassan II de FES (étude de 215 patients).

INTRODUCTION: Although several studies have tried to identify the causes of failure of dacryocystorhinostomy (DCR) surgery, the ethmoid sinus remains an underestimated and little described source of failure. OBJECTIVE: To study anatomical relationship between the ethmoidal sinus, particularly the "Agger nasi" cell, with the lacrimal fossa in the North African population, little described in the literature. This study is based on the results of preoperative analysis of dacryo-computed tomography. PATIENTS AND METHODS: Analysis of preoperative computed tomography images of patients undergoing dacryocystorhinostomy over a 7-year period from January 2011 to December 2017. Anatomical relationships were studied according to the following classification: type I: No ethmoid cells located anteriorly to the posterior lacrimal crest on transverse images; type II: ethmoidal cells extending anteriorly to the posterior lacrimal crest, but not reaching the anterior edge of the lacrimal bone; Type III: ethmoidal cells located anterior to the lacrimal bone suture. RESULTS: Two hundred and fifteen preoperative computed tomography images were analyzed. The morphology of the ethmoid sinus was classified as type 1 in 33.5%, type 2 in 42.32% and type 3 in 24.18%. Computed tomography analysis was symmetrical in 87.5% and asymmetrical in 12.5%. CONCLUSION: During dacryocystorhinostomy, the surgeon must take into consideration type III, which can be present in 25% of cases. In the case of surgical failure, a dacryo-CT must be performed to rule out such anterior positioning of the ethmoid cells.

[Embryology and anatomy of the thorax and breast]. / Embryologie et anatomie du thorax et du sein.

Embryology and anatomy of the chest wall and breast will be developed in this chapter. The walls of the thorax will be described; the anatomical notions of thoracic deformities will be detailed. The anatomy of the mammary gland will be developed around the understanding of the means of fixity and vascularization. The anatomical descriptions come from the writings of ancient anatomists, notably Testut and Latarjet, as well as the iconographies taken from their various works.

[An initial lack of knowledge of the perineal anatomy does not influence the learning of intermittent self-catheterization in women]. / La méconnaissance initiale de l'anatomie périnéale n'influence pas l'apprentissage de l'auto-sondage intermittent chez la femme.

AIM: To evaluate the impact of female perineal anatomy knowledge on the success of a first learning of intermittent self-catheterization (ISC). METHODS: Thirty subjects benefited from educational diagnosis, training and follow-up during 2 visits in a neuro-urology department. Three knowledge anatomical tests were carried out: a freehand drawing, then a diagram to be annotated and a self-location of the following 6 structures (labia majora, labia minora, clitoris, urethral meatus, vaginal orifice, anus) as well as a physiological knowledge test. A correction was made after annotating the diagram to perfect the learning process before performing the procedure. RESULTS: Of the women studied, 83.3% had a neurological pathology and 77.7% had a gyneco-obstetrical history. Half of them had undergone perineal rehabilitation. Our study shows a lack of knowledge of the perineum prior to learning self-catheterization: 43.3% thought they knew it partially and 46.7% reported that they did not know it. Fifty-three percent of the subjects did not indicate the urethral meatus and 43.3% did not annotate the vaginal orifice on the diagram. Difficulties in anatomical transposition were observed: the urethral meatus was self-located in only 43.3% of subjects and 30% did not locate the vaginal orifice. Previous perineal rehabilitation was not benefical in the self-recognition of anatomical structures. However, all the patients, including those who did not initially locate the urethral meatus, acquired the technique of ISC. CONCLUSION: Intial perineal anatomy ignorance in women was frequent but was not an obstacle to learning ISC. LEVEL OF PROOF: 4.

[Two experimental models for wound vitality evaluation in forensic pathology: A clinical prospective non-interventional study and an animal model]. / Présentation de deux modèles expérimentaux pour l'étude de la vitalité des plaies en pathologie médico-légale : une étude clinique prospective non interventionnelle et un modèle animal.

AIM OF THE STUDY: In forensic pathology, wound age evaluation allows to determine if a wound was inflicted before or after death, and to date wounds of different ages. This dating is performed in conventional histopathology by observing inflammatory cells and hemorrhage at the wound site. However, these criteria seem to show low sensitivity and/or specificity. The aim of our study was to compare two models of wound vitality evaluation: a human surgical model, and a porcine experimental model; using these histological criteria. PATIENTS AND METHOD: In the two human (n=38) and porcine (n=11) models, three wounds were performed at regular time-lapse before devascularization/sacrifice, and a control wound after devascularization/sacrifice. The main evaluation criteria were the presence of interstitial hemorrhage and the number of interstitial polymorphonuclear neutrophils at 10 high power fields. RESULTS: In the two models, the number of polymorphonuclears neutrophils was significantly higher in vital wounds compared to the post-devascularization/sacrifice wounds (P<0.001), with a very low sensitivity (human model: 4.3%; porcine: 47%). Hemorrhagic infiltration was more frequent in vital wounds (human: P<0.001; porcine: P=0.01), with a low specificity (human: 48%; porcine: 54%). DISCUSSION AND CONCLUSION: This first study confirms, in the two models, the limitations of conventional histopathology in wound vitality evaluation. The next step will be testing several immunohistochemical markers in the two models.

[Assessment of trainee urologists' knowledge in urogenital anatomy]. / Évaluation des connaissances en anatomie uro-génitale des urologues en formation.

The purpose of this study was to assess trainee urologists' [interns and assistant heads of university hospitals (CHU)] knowledge of the anatomy of the urogenital system. An examination consisting of 10 timed (16minutes) multiple-choice questions (MCQ) based on urogenital anatomy assessments for students in third year of the general medical science diploma program (DFGSM3) was sent to members of the French Association of Trainee Urologists (AFUF) in May 2018 in order to compare the average scores of these two populations. In addition, a questionnaire consisting of epidemiological data, their opinion on the quality of education in anatomy and the willingness to have more courses on this subject was included in the examination. The same scale based on a score out of 20 was applied to both populations. Of the 501 AFUF members solicited, 144 answered all the questions (28.7%). The mean score for urologists was lower than that of DFGSM3 students (10.56±1.82 vs. 11.4±2.37 respectively) (P=0.0013). Moreover, the desire for further education in anatomy was widespread among urologists (87%). According to our study, urologists have less knowledge of urogenital anatomy than third year medical students. Many means are being implemented or are available to rectify this failing, especially since the majority of trainee urologists consider that there are insufficient anatomy lessons in the curriculum and would like to receive further education in anatomy. LEVEL IF EVIDENCE: 3.

[Forensic autopsies and pathological examination: Current practice in Montpellier's jurisdiction. A retrospective study of 630 autopsies]. / Autopsies judiciaires et expertises anatomopathologiques complémentaires : état des pratiques sur le ressort de la cour d'appel de Montpellier. Étude rétrospective de 630 autopsies.

INTRODUCTION: In France, pathological examination is not systematically required in forensic autopsies. The factors affecting the decision to carry out a pathological expertise have not yet been defined. The aim of this study was to describe in which conditions a pathological expertise was required after forensic autopsy by the high court of Montpellier. METHODS: This study included and analyzed retrospectively all of the autopsy elements, of all forensic autopsies carried out over a year. These elements were classified: pre-autopsy, per-autopsy, and post-autopsy. RESULTS: A pathological expertise was required in 19.2% of 630 cases, among which 31% in a context of undetermined cause of death and in 14% of cases of determined causes of death. The forensic practitioner recommended a pathological expertise in 10 to 31% of autopsies. Overall, 64 pathological examinations were realized out of 121 recommended examinations (52.9%), this rate varied from 25 to 73% depending on the court. The magistrate tended to favor anatomopathological expertise in cases of determined causes of death, and in certain manner of death (80% homicide versus 35% natural). The pathologist's expertise enabled to change the cause of death in 22% of cases and the manner of death in 19%. The pathological approach was a major asset in the 65% of unknown manner of deaths and in the 20% of natural, whereas the expertise did not help in cases of homicides, suicides and accidents. The cause of death was modified in 5.6% of initially determined causes of death, against 42.9% in case of initially unknown cause. CONCLUSION: The use of pathologic examination in forensic autopsies is scarce and uneven. The factors resulting to its request are not directly linked to its scientific assets. A conjoint work between forensic and pathologist practitioners would be beneficial.

Morphological analysis of myocardial bridges and coronary arterial dominance in northeast Brazil.

BACKGROUND: Coronary arterial dominance and myocardial bridges have clinical implications, since a left dominant pattern associated to the presence of myocardial bridges is often associated to a higher incidence of arteriosclerosis and higher mortality by myocardial infarction. OBJECTIVE: To determine the presence and position of myocardial bridges and their relation with coronary arterial dominance. METHODS: Fifty-seven human cadaveric hearts were analyzed into three groups, as follows: right dominance; left dominance; codominance. Each group was then divided into two subgroups: with or without myocardial bridges. Finally, each subgroup with myocardial bridges was classified according to the position of the myocardial bridge according to the main axis of the heart (proximal, middle and distal third). RESULTS: The right dominance occurred in most hearts (30 hearts-52,6%). Twenty-three myocardial bridges (40,3%) were identified and mostly occurred on left dominant hearts (22,8%). The pattern of coronary dominance presented a statistically significant correlation with the presence of myocardial bridges (P=0.048). The middle third of the heart axis showed the highest occurrence of myocardial bridges. CONCLUSION: These findings suggest there is a clear relationship between the presence of myocardial bridges and left dominant pattern. Middle third of the heart axis present the higher occurrence of myocardial bridges. Knowledge of the myocardial bridges morphology is of great clinical significance, improving patient care.

[Pathologies of the spine]. / Les pathologies du rachis.

Spinal pathology is a major public health problem. It is sometimes referred to as the "disease of the century" due to the increasing number of people affected. It can be low back pain or neck pain, but whatever the mechanism and the age of the patient, its consequences on the quality of life are undeniable. In the case of scoliosis, which can cause an alteration in body image in young patients, treatment requires, in addition to possible surgery, long-term support.

[Prospective forensic study on the characterization of genital examination in women with consented sexual activity]. / Étude médico-légale prospective sur la caractérisation de l'examen génital chez des femmes ayant une activité sexuelle consentie.

OBJECTIVE: The number of women victims of sexual assault remains high, despite prevention and information campaigns. These victims can be adolescent girls, women of childbearing age or postmenopausal women. As part of examinations of victims of sexual assault, the morpho-anatomical diversity of the female genitalia requires knowledge of the physiological variations existing by the practitioners caring for these victims. Our work aimed to describe and characterize the genital examination of women with consented sexual activity. METHOD: Our cohort consisted of 196 women aged 14 to 81, examined in the context of medical gynecology consultations in two French maternity hospitals. RESULTS: Recent genital traumatic injuries were found in 12.8% of women whose last sexual intercourse was less than 5days old. Intact hymens, free from traumatic tearing despite regular sexual activity, were present in 10.7% of these women. CONCLUSION: Thus, in many cases, genital examination alone cannot confirm or deny the existence of prior sexual intercourse, whether or not it was consented to. The development of work on data on female genital anatomy would make it possible to optimize the medico legal care of victims of sexual assault.

[Vulva anatomopathological peculiarities]. / Particularités anatomo-pathologiques de la vulve.

The vulva is the transition zone between the skin and the lower genital tract. As such, it presents histological specificities, comprises physiological modifications which are specific to it and is characterized by particular artifacts. Knowledge of them prevents many questions or even diagnostic errors.

[Focus on axillary anatomy: The Carl Langer muscle, a great forgotten muscle in the training of medical residents in gynecology and obstetrics]. / Mise au point sur l'anatomie de la région axillaire : l'arc musculaire du grand dorsal ou muscle de Carl Langer, un grand oublié dans la formation des internes.

OBJECTIVE: The Carl Langer muscle is the main anatomical variation of the walls of the axillary area, its incidence being about 7%. The presence of this muscle crossing the anterior edge of the axillary vessels can induce difficulties of exposure, location and dissection during axillary surgery. In addition, it may be responsible for primary lymphedema of the upper limb, venous thrombosis of the axillary vein or thoracic outlet syndrome due to vascular or nervous compression. The objective of this work was to evaluate the state of knowledge on Carl Langer muscle of the gynecology-obstetrics medical residents of the French Eastern Region. MATERIAL AND METHODS: All the medical residents enrolled in the specialized diploma in gynecology-obstetrics in the 5 regions (Alsace, Bourgogne, Lorraine, Champagne-Ardenne and Franche-Comté) were questioned by means of a questionnaire sent by e-mail. RESULTS: From February to March 2021, 94 of the 160 medical residents interviewed answered to the questionnaire. Ninety-one of them (97%) did not know Carl Langer's muscle. Three medical residents thought they knew this muscle (3%) but their knowledge was imperfect. CONCLUSION: Our work has highlighted the general lack of knowledge of this anatomical variation, which is relatively frequent, among French gynecology-obstetrics medical residents who are required to examine or perform surgery on this area. This updated review of the literature should optimize the knowledge of the anatomy of the axillary area and consequently its surgery.
