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.

Adequate Knowledge

Variations of nerve are not only of anatomic and embryological interest but also of clinical importance. Their adequate knowledge will help in increasing surgical precision and decreasing morbidity. Anatomical variations in the formation of the sural nerve are common, although the topographical localization of this nerve is constant. In this report, we describe a case of an anomalous course of the medial sural cutaneous nerve which descended through the gastrocnemius via a tunnel formed within the muscle. Such anatomical variation of the sural nerve is clinically important when evaluating sensory axonal loss in distal axonal neuropathies since sural nerve mononeuropathy is less likely to occur.

Anatomical variation in the lower limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. While examining 25 skulls present in the department of Anatomy, Universiti Sains Malaysia, we found that in one of the skull the floor of the carotid canal was absent on both the sides. The absence of the floor, exposed the roof of the carotid canal which appeared as a deep groove extending on the under surface of the petrous temporal bone. Following review of literature, we found that absence of the carotid canal is a very rare anomaly and has a great clinical importance. Exposed internal carotid artery in the absence of floor can make it at risk of injury during skull base surgeries. Therefore, we decided to report this case.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.275-277

Symptomatic Stenosis

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.

International Experts

Since the 1990s numerous international experts have reported about the somatic complications of eating disorders including those having a dental and stomatological nature. Several reports emphasised that deformations in the oral cavity resulting from this grave nutritional disease typical of the young generation could already appear in the early stage and, therefore, dentists are among the first to diagnose them. Dentists are still often unaware of the importance of their role in multidisciplinary treatment. Even if they knew what the disease was about and recognised it on the basis of deformations in the oral cavity in time, their advice that their patients should brush their teeth more often would fail to eliminate the root cause of the problem. Not only the earliest possible treatment of the complications of the bingeing-purging mechanism and the maintenance of oral hygiene are important, but controlling and curing pathological habits with active participation of psychiatrists are also required to ensure full recovery. Due to the multidisciplinary nature of the disease, manifold communication is required. For this reason, publishing the dental ramifications of organic and systemic diseases at dental conferences and in technical journals, as well as providing information about oral complications of eating disorders for general practitioners and specialists are particularly important.

Structure Education

There is a growing need for expertise both in image analysis and in software engineering. To date, these two areas have been taught separately in an undergraduate computer and information science curriculum. However, we have found that introduction to image analysis can be easily integrated in data-structure courses without detracting from the original goal of teaching data structures. Some of the image processing tasks offer a natural way to introduce basic data structures such as arrays, queues, stacks, trees and hash tables. Not only does this integrated strategy expose the students to image related manipulations at an early stage of the curriculum but it also imparts cohesiveness to the data-structure assignments and brings them closer to real life. In this paper we present a set of programming assignments that integrates undergraduate data-structure education with image processing tasks. These assignments can be incorporated in existing data-structure courses with low time and software overheads. We have used these assignment sets thrice: once in a 10-week duration data-structure course at the University of California, Santa Barbara and the other two times in 15-week duration courses at the University of South Florida, Tampa.

This scientific article discusses the oral manifestations of diseases of the gastrointestinal tract. This problem is relevant both for dentists and family doctors. In medicine, for a long period of time, the relationship between diseases affecting the gastrointestinal tract and their symptoms manifested in the oral cavity has been considered. Many scientists and physicians have dealt with this problem, their several opinions are presented in this article. There is a hypothesis among researchers that the oral cavity is a mirror in which all human diseases can be visible. In the oral cavity, most of the alterations occurring in the organism are manifested, due to which, with an attentive attitude to oral manifestations, the disease can be detected already at the initial stage.

The purpose of this paper is to analyze the websites of university libraries to ascertain that libraries are effectively utilizing their respective websites to provide easy access to all electronic resources available in the library. The objective was also to a represent a comparative analysis between public and private university library websites regarding the presence of electronic resources with their easy access via the internet. For the purpose of this study, a research instrument in the form of comprehensive checklist of eighteen e-resources was developed to evaluate their accessibility in the websites of public and private university libraries. Twenty university library websites, comprised of ten top-ranked public and ten top-ranked private universities in Bangladesh, were studied for data collection using content analysis method. The findings demonstrate that the presence of e-resources on selected university library websites is still in its early stage, but it has been growing rapidly. The private university library websites are ahead of public university libraries in terms of the integration of web-resources. It is hoped that the findings of this paper will serve to assist the University librarians and other similar institutions in choosing, selecting and acquiring the most appropriate format of information resources, and making these available to their websites, which will both satisfy the needs of their library users and fit within their library budget.

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
