The preslaughter stunning of bovine animals is a legal requirement in the European Union, unless the animal is being slaughtered according to religious rite. The legislation also requires the investigation and review of stunning methods in cases of failure to stun. This paper presents the results of one investigation into the possible reasons for multiple stun attempts on an animal that received five shot applications. The head was hard frozen to prevent the deformation of brain structures during splitting along the sagittal plane, and then underwent macroscopic examination to assess the likely causes of the repeated stun attempts. In this case, a pre-existing chronic disease process produced anatomical variations of the cranial cavity, increasing the thickness of the sinuses of the frontal bone to a depth of 9 cm and filling the sinuses with a fibrinous pus deposit. It was therefore concluded that the anatomical variation produced by the chronic disease process, in addition to the energy absorption provided by the thicker hide and fibrinous pus, led to the failure of the stunning equipment to achieve the desired stunned state in the animal. As the animal displayed cranial variation before slaughter, a review of the stunning systems should include a requirement that animals displaying any abnormalities should be stunned with the highest-powered cartridge available or a free bullet.

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

Object The C-7 lateral mass has been considered difficult to fit with instrumentation because of its unique anatomy. Of the methods that exist for placing lateral mass screws, none particularly accommodates this anatomical variation. The authors have related 12 distinct morphological measures of the C-7 lateral mass to the ability to place a lateral mass screw using the Magerl, Roy-Camille, and a modified Roy-Camille method. Methods Using CT scans, the authors performed virtual screw placement of lateral mass screws at the C-7 level in 25 male and 25 female patients. Complications recorded included foraminal and articular process violations, inability to achieve bony purchase, and inability to place a screw longer than 6 mm. Violations were monitored in the coronal, axial, and sagittal planes. The Roy-Camille technique was applied starting directly in the middle of the lateral mass, as defined by Pait's quadrants, with an axial angle of 15° lateral and a sagittal angle of 90°. The Magerl technique was performed by starting in the inferior portion of the top right square of Pait's quadrants and angling 25° laterally in the axial plane with a 45° cephalad angle in the sagittal plane. In a modified method, the starting point is similar to the Magerl technique in the top right square of Pait's quadrant and then angling 15° laterally in the axial plane. In the sagittal plane, a 90° angle is taken perpendicular to the dorsal portion of the lateral mass, as in the traditional Roy-Camille technique. Results Of all the morphological methods analyzed, only a combined measure of intrusion of the T-1 facet and the overall length of the C-7 lateral mass was statistically associated with screw placement, and only in the Roy-Camille technique. Use of the Magerl technique allowed screw placement in 28 patients; use of the Roy-Camille technique allowed placement in 24 patients; and use of the modified technique allowed placement in 46 patients. No screw placement by any method was possible in 4 patients. Conclusions There is only one distinct anatomical ratio that was shown to affect lateral mass screw placement at C-7. This ratio incorporates the overall length of the lateral mass and the amount of space occupied by the T-1 facet at C-7. Based on this virtual study, a modified Roy-Camille technique that utilizes a higher starting point may decrease the complication rate at C-7 by avoiding placement of the lateral mass screw into the T1 facet.

Background: The purpose of this paper is to describe an anatomical variation of the hand extensor on the little finger of the right hand which receives four tendons, condition unknown, as it is the first case reported so far in the literature. The human extensor tendons of hand often display an array of variations. Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary not only for the anatomist but also for surgeons when considering tendons for hand surgery, tendon rerouting or transplants. Materials and Methods: Bilateral anatomical variation in the upper limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. The variations were recorded and photographed. Result: In the left hand the extensor digitorum there was a single tendon to the index, double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand the extensor digitorum there was a single tendon to the index, triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons, 2 of extensor digitorum and 2 of extensor digiti minimi. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd intermetacarpal space; type 3, between the extensors tendons in the 4th inter metacarpal space. Conclusion: The presence of multiple tendons may alter the kinematics around the site of attachment to the phalanx. Knowledge of anatomical variations and normal anatomy of the extensor tendons, may be helpful while performing graft and tendon transfer operations.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.278-282

This retrospective study was conducted to find out the expected ages in the patients of hepatic cirrhosis, chronic renal failure and heart failure. This study thus covers most of the patients of out medical wards presenting with chronic illnesses. On comparison of these expected ages it is also found that the expected age in all these three groups is not much different. So, the disease process or the mechanism of the chronic disease in the body may be different, but somehow the final out come is not much different in terms of life span.

Background: The paired parotid glands are the largest of the major salivary glands and produces mainly serous secretions. The secretion of this gland reaches the oral cavity through single parotid duct (Stensen’s duct). The parotid duct begins at the anterior border of the gland, crosses the masseter muscle, and then pierces the buccinator muscle to reach the mucosa lining the mouth at the level of the cheek. The purpose of this study is determine the morphologic features of the parotid duct and describe an anatomical variation until now unreported. Methods and Findings: A total of 17 cadavers were used for this study in the Morphology Laboratory at the University of Pamplona. In a cadaver were findings: The main parotid duct originated two conducts: Left superior parotid duct and Left inferior parotid duct, is observed the criss-cross of the ducts, and then perforated the buccinator muscle and entered the oral cavity at a double parotid papilla containing a double opening, separated from each other in 0,98 mm. In the remaining  33 parotid regions (97.06%) the parotid duct is conformed to the classical descriptions given in anatomical textbooks. Conclusions: The parotid duct anatomy is important for duct endoscopy, lithotripsy, sialography and trans-ductal facial nerve stimulation in the early stage of facial palsy in some cases. The anatomical variations also has clinical importance for parotid gland surgery and facial cosmetic surgery. To keep in mind the parotid duct variation will reduce iatrogenic injury risks and improve diagnosis of parotid duct injury.

Introducción: El tratamiento endodontico representa en la actualidad una gran rama en el área de la odontología de importancia para la preservación de piezas dentales, que se verían afectadas por el ataque de agentes externos y que comprometen su funcionabilidad y estética, pero la complejidad de la anatomía de los conductos de todos los dientes en general aún sigue siendo un problema, más aun en los premolares, ya que estos a diferencia de las demás piezas dentarias, tienen diferentes formas y cantidad de conductos radiculares. (6) Propósito: El propósito de este estudio es demostrar la importancia del conocimiento sobre la anatomía radicular y sus variaciones anatómicas, para minimizar el fracaso al realizar una terapia endodontica. Objetivo: El objetivo directo de este estudio es determinar las variaciones anatómicas de premolares superiores e inferiores y su relación con estructuras anatómicas de pacientes atendidos endodónticamente, el año 2016, en la clínica Nexodent de la ciudad de Guayaquil, mediante el uso de sus tomografías previas a  su tratamiento.Materiales y métodos: Se analizaron 70 tomografías de 41 pacientes atendidos en el año 2016 en la clínica Nexodent de la ciudad de Guayaquil. Al momento de analizar cada tomografía se tomaron tres fotografías de cortes tomografcos: coronal, axial y sagital para obtener una información variada de su anatomía. Resultados: De las tomografías revisadas, el 71% fue de género femenino. El 29% de género masculino. Los resultados encontrados del número de conductos en las piezas dentales registradas señalan que el 56% de los casos presenta 1 sólo conducto. En cuanto a la variación anatómica de las piezas dentales estudiadas, se utilizó la clasifcación de Vertucci. El 56% de las piezas dentales es de Tipo I, el 26% es de Tipo IV, el 11% es de Tipo II, y el restante son de Tipo V. Se analizó la distancia entre cada premolar maxilar hasta el seno maxilar y en promedio la distancia fue de 5,3 mm. La distancia promedio de los premolares mandibulares hasta el foramen mentoniano fue de 6,21 mm. La principal localización encontrada para el orifcio del foramen apical fue el centro con el 58% de los casos.Discusión: Se obtuvo mayoría de aciertos sobre los estudios realizados con los estudios de las referencias bibliográfcas excepto en; La incidencia de los conductos en los segundos premolares superiores en que se obtuvo mayoria de un conducto en lugar de dos. En la distancia promedio del apice de los primeros premolares mandibulares con el agujero mentoniano en donde las distancias promedios fueron mayores. En la localizacion del foramen apical en la pieza #35, en que hubo mayor localizacion del foramen en el centro y no hacia distal.Conclusión: Se puede concluir que el mejor examen complementario para analizar la anatomía de conductos es la tomografía y que los resultados obtenidos en esta investigación no fueron muy distintos en comparación a investigaciones realizadas por otros autores.    AbstractIntroduction: Endodontic treatment currently represents a large branch in the area of dentistry of importance for the preservation of dental pieces, which would be afected by the attack of external agents and compromise its functionality and aesthetics, but the complexity of the root Canals anatomy of all teeth in general still remains a problem, even more so in the premolars as these unlike other teeth, have diferent forms and quantity of root Canals. 6 Purpose: The purpose of this study is to demonstrate the importance of knowledge about the root canal anatomy and its anatomical variations, in order to minimize the failure in an endodontic therapy.Objective: The direct objective of this study is to determine the anatomical variations of upper and lower premolars and their relationship with anatomical structures of endodontically treated patients, in 2016, at the Nexodent Clinic of the city of Guayaquil, using their tomography prior to its treatment. Materials and methods: We analyzed 70 CT scans of 41 patients seen in 2016 at the Nexodent clinic in the city of Guayaquil. At the moment of analyzing each tomography three photographs were taken: coronal, axial and sagittal to obtain al the information of its anatomy. Results: Of the CT scans reviewed, 71% were female, 29% male. The results found of the number of root canals in the registered dental pieces indicate that 56% of the cases present 1 only conduit. Regarding the anatomical variation of the studied dental pieces, the Vertucci classifcation was used 56% of the teeth are Type I, 26% are Type IV, 11% are Type II, and the rest are Type V. The average distance between the maxillary premolars to the maxillary sinus was 5.3 mm. The mean distance from the mandibular premolars to the mental foramen was 6.21 mm. The main location found for the apical foramen was the center with 58% of the cases. Discussion: the mayority of the studies carried out with the studies of the bibliographical references where equal except in; The incidence of root canals in the upper second premolars where the mayority of one root was obtained instead of two. In the average distance of the apex of the frst mandibular premolars with the mental foramen where the average distances were greater. In the location of the apical foramen in # 35, in which there was greater location of foramen in the center and not distal. Conclusion: It can be concluded that the best complementary exam to analyze the anatomy of root Canals is the tomography and that the results obtained in this investigation were not very diferent  in comparison to investigations realized by other authors.

Objective:To evaluate role of Diagnostic Nasal Endoscopy and CT scan in various Sinonasaldiseases with regards to diagnosis and surgical intervention. Patient and methods:This prospective study was carried out in Department of ENT, A.N.M.M.C.H., Gaya on 200 patients with clinical evidence of sinonasal disease who had presented between March 2016 to February 2019. All patients were evaluated with DNE using 0 degree 4mm endoscope and CT scan with 3 mm coronal cuts. Result: Female patients(56%) were more as compared to male(44%) with majority between 21 - 40 yrs. Most common finding on Diagnostic Nasal Endoscopy(DNE) was mucopurulent discharge in middle meatuswhile on CT Scan was maxillary sinusitis(60%). Sinonasal polyp detection was better with DNE.CT has better detection rate of anatomical variation of osteomeatal complex. Conclusion : DNE has become initial tool for diagnosis as it is cost effective and office based procedure. In patients where surgical intervention is required, CT scan has advantage as it provides detailed understanding of anatomical variations. So bothDNE and CT scan should be used in collaborative fashion. Source Of Support:Patients of A.N.M.C.H., Gaya. Conflict Of Interest:None.

AbstractBackgroundNonsurgical lip enhancement using dermal fillers is a very popular procedure. The trend for enlarged lips has been popularized by media and social media. The lips have considerable aesthetic and functional importance, in addition to having a complex anatomy. Serious complications, including vascular compromise or occlusion leading to cutaneous necrosis and blindness, can occur as the result of lip enhancement using dermal fillers. Therefore, aesthetic practitioners require an in-depth understanding of the anatomy and vasculature of the lips and the perioral area prior to providing lip enhancement using dermal fillers.ObjectivesThis literature review aimed to summarize existing data describing the origin, path, and depth of the superior and inferior labial arteries, and to help aesthetic practitioners in providing safer injections to the lips.MethodsA literature search was carried out to summarize the available data describing the origin, path, and depth of the labial arteries.ResultsAnalysis of the literature revealed that the labial arteries display great variability with respect to path (distribution), presence, and location.ConclusionsIncreasing the volume of lips through injections of dermal filler needs to be undertaken with caution, and awareness of the anatomical variation in artery location and path is a crucial concept that is essential when injecting the lips.

IntroductionMore than 70% of world mortality is due to chronic conditions. Furthermore, it has been proven that social determinants have an enormous impact on both health-related behaviour and on the received attention from healthcare services. These determinants cause health inequalities. The objective of this study is to reduce the burden of chronic diseases in five European regions, hereby focusing on vulnerable populations, and to increase the sustainability of health systems by implementing a chronic disease self-management programme (CDSMP).Methods and analysis2000 people with chronic conditions or informal caregivers belonging to vulnerable populations, will be enrolled in the CDSMP in Spain, Italy, the UK, France and the Netherlands. Inclusion of patients will be based on geographical, socioeconomic and clinical stratification processes. The programme will be evaluated in terms of self-efficacy, quality of life and cost-effectiveness using a combination of validated questionnaires at baseline and 6 months from baseline.Ethics and disseminationThis study will follow the directives of the Helsinki Declaration and will adhere to the European Union General Data Protection Regulation. The project’s activities, progress and outcomes will be disseminated via promotional materials, the use of mass media, online activities, presentations at events and scientific publications.Trial registration numberISRCTN70517103; Pre-results.
