Knowledge of normal anatomy and physiology of swallowing is fundamental in the identification of individuals with orat risk for swallowing disorders. Learning anatomy and physiology however, is not an easy task thus, computer-assistedlearning (CAL) approaches have been incorporated into the learning of the topics to enhance understanding. Althoughevidence exists on the benefits of using CAL in education, more studies are necessary in the field of swallowing. Whilecourseware for the learning of anatomy and physiology of swallowing exist, they are not comprehensive. Therefore, thisstudy aimed to develop a comprehensive CAL courseware for anatomy and physiology of swallowing. The current studyused a designed-based research following the ADDIE (analysis, design, development, implementation, and evaluation)model to create a multimedia courseware, incorporating the use of text, still images, animations, audio narrations,and presented on a simple graphical user interface. The courseware was evaluated by 27 undergraduate students interms of its usefulness, ease of use, and users’ satisfaction. Results indicate that the participants were satisfied with thecourseware and that they perceived the courseware as useful, easy to learn and easy to use. The study represents aninitiative to investigate the use of CAL in the subject and to establish the basis for further work which includes assessmenton the learning outcomes from the usage of the CAL courseware. It is hoped that the use of this courseware in teachingand learning of anatomy and physiology of swallowing can enhance students’ knowledge and understanding of the areaefficiently and effectively.

Background: Oral cavity cancers, the second most common type in India, are responsible for 10% of the overall cancer burden. With a recurrence rate of 30% to 40% and a 5-year survival rate of 50%, these malignancies account for substantial morbidity and mortality. Despite advances in treatment modalities, survival rates following treatment completion have not improved significantly. The present study aimed to establish specific epidemiological and pathological factors responsible for recurrence after treatment completion in buccal mucosa cancers. Methods: A retrospective analysis of the data of 116 patients treated for biopsy-proven cancers of the buccal mucosa was undertaken 1 year after treatment completion. Factors such as age, sex, education, lymphovascular invasion, extranodal extension (ENE), perineural invasion, depth of invasion, and pathological margin status were compared between patients who presented with recurrence and those who did not. Statistical significance was set at p< 0.05. Results: Of the 116 patients, 40 (34.5%) developed a recurrent disease within 1 year. The mean age of the study population was 43.3 years, and males constituted 91.4% of the included patients. Ipsilateral buccal mucosa was the commonest site of disease recurrence. Neck node metastasis, ENE, and margins of resection < 5 mm were significantly related to the recurrence of disease. However, surprisingly, lymphovascular invasion, perineural invasion, and depth of invasion > 10 mm did not show statistically significant associations. Conclusion Neck node metastasis, ENE, and margins of resection < 5 mm were the histopathological factors associated with recurrence in cancers of the buccal mucosa.

Objective: To describe a rare case of lipofibromatosis presenting as a head and neck mass in a 6-year-old child. Method: Design: Case Report Setting: Tertiary Public General Hospital Patient: One Result: A six-year-old male child admitted with a large right head and neck region mass underwent complete excision of a possible soft tissue neoplasm following investigations which included Fine Needle Aspiration Cytology, Ultrasonography and Computed Tomography. Histopathological examination yielded lipofibromatosis, a very rare lesion with a distinctive fibrofatty pattern. The patient was well with no recurrence after three months of follow up. Conclusion Although lipofibromatosis is a rare lesion in children and has a predilection for distal extremities, it may also present as a mass in the head and neck area. Complete surgical excision is feasible and is the only treatment option available for this rare lesion
