The relationship of educational environment and preparedness to practice - perceptions of Malaysian dental graduates.

Gauging dental graduates' perceptions of their university training and of how it prepares them for professional practice is useful in measuring the quality and adequacy of the curriculum to which they were exposed. OBJECTIVES: This study aimed to evaluate the perceptions of dental graduates' educational environment as well as preparedness to practice, and how these two components are correlated. METHODS: A self-administered, validated questionnaire, developed from previous studies, was distributed to dental graduates of a public Malaysian university (n = 178, response rate = 60%) via online and postal surveys. Bivariate analyses were carried out using Spearman's rank-order correlation (Spearman's Rho, significance level p < .01) to determine the correlation between (1) Global Preparedness Score and Global DREEM Score, (2) domains of DREEM Inventory and perceived preparedness, and (3) domains of perceived preparedness and DREEM Score. RESULTS: The Global Preparedness Score was 191.52, with more than 90% of respondents feeling well prepared in the "General Patient Management," "Drug and Emergency Management" and "Practice Management" domains. The Global DREEM Score was 148.99/200, interpreted as "more positive than negative." The DREEM Inventory domains with the highest and lowest scores were "Students' Academic Self-Perception" (78.03%) and "Students' Social Self-Perception" (71.86%), respectively. A moderate positive correlation was found between Global Preparedness Score and Global DREEM Score (p < .01). In addition, moderate to large positive correlations were noted between perceived preparedness and "Student Perception of Learning," "Student Perception of Atmosphere" and "Student Academic Self-Perception" (p < .01). Moderate positive correlations were also found between the DREEM Score and most domains of perceived preparedness (p < .01). CONCLUSIONS: The majority of graduates were well prepared to perform in most areas of clinical practice and perceived their overall educational environment as positive. In particular, those who viewed the educational environment in a positive light were also found to possess a good level of preparedness.

Acute pericarditis as a clinical manifestation in COVID-19 infection in a district hospital setting.

The global outbreak of coronavirus disease 2019(COVID-19) pandemic has heavily impacted the health service, leading to increased mortality and morbidity. Although known to manifest primarily as a respiratory illness, there are reports of cardiac involvement as extrapulmonary manifestation. We are reporting a case of pericarditis in a young patient who presented with only cardiac symptoms in COVID-19. He was admitted to the hospital for observation and treated with oral colchicine and oral ibuprofen. His conditions improved and subsequently discharged well. Acute pericarditis can present as part of the COVID-19 extrapulmonary spectrum. Therefore, it is important and challenging for clinicians to recognise the atypical presentations of COVID-19 to reduce morbidity and mortality.

The pathogenesis of mucositis: updated perspectives and emerging targets.

Mucositis research and treatment are a rapidly evolving field providing constant new avenues of research and potential therapies. The MASCC/ISOO Mucositis Study Group regularly assesses available literature relating to pathogenesis, mechanisms, and novel therapeutic approaches and distils this to summary perspectives and recommendations. Reviewers assessed 164 articles published between January 2011 and June 2016 to identify progress made since the last review and highlight new targets for further investigation. Findings were organized into sections including established and emerging mediators of toxicity, potential insights from technological advances in mucositis research, and perspective. Research momentum is accelerating for mucositis pathogenesis, and with this has come utilization of new models and interventions that target specific mechanisms of injury. Technological advances have the potential to revolutionize the field of mucositis research, although focused effort is needed to move rationally targeted interventions to the clinical setting.

Awareness of forensic odontology among dentists in Australia: are they keeping forensically valuable dental records?

BACKGROUND: Forensic odontologists provide an important service to the community by identifying unknown deceased people, allowing both legal outcomes and family closure. Non-visual identification may be achieved by comparison of post-mortem data with ante-mortem dental records provided by oral health practitioners. Success is dependent largely on the accuracy and adequacy of data in the dental records. METHODS: An online self-administered questionnaire evaluated Australian dentists' knowledge and behaviours relevant to forensic odontology. Reported record keeping practices were assessed for detail, legibility, accessibility and retention. Behaviours were classified according to the frequency of response. RESULTS: Dentists reported overall reasonable awareness of the major applications of forensic odontology. Personal information and details of restorative treatment were recorded at high levels, while tooth anomalies, photography, additional patient details and denture marking were recorded inadequately. Legible tooth coding was reported at a high level, while other key legibility practices were recorded inadequately. Few of the behaviours related to retention or to maximize accessibility were recorded at a high level. CONCLUSIONS: Australian dentists have high expectations of the forensic value of their dental records; however, many processes that would enhance the diagnostic, medico-legal and forensic value of dental records are not routinely applied.

Matrix metalloproteinases: do they play a role in mucosal pathology of the oral cavity?

Matrix metalloproteinases (MMPs) are critical factors in maintaining the integrity of mucosa and mediating normal biological processes. An imbalance between tissue levels of these mediators and their natural inhibitors is believed to underlie the pathophysiology of many diseases, including those affect the gastrointestinal and oral mucosae. The ongoing development of synthetic inhibitors of these mediators may provide opportunities to develop treatment modalities for patients suffering from these diseases. Understanding the role of MMPs in the pathophysiology of many diseases, however, is far from complete, and the improvement of pharmaceutical management strategies can only be achieved if the underlying process of these diseases is completely comprehended. This paper reviews the functions of matrix metalloproteinases and addresses their role in mediating mucosal pathologies with emphasis on oral mucosa.

Surveillance For Sarcocystosis In Tioman Island, Malaysia

In October 2011, the National International Health Regulations (IHR) 2005 Focal Point for Malaysia received notification from the United States’ Centers for Disease Control and Prevention (CDC) of a probable Sarcocystis outbreak amongst 23 travellers from six countries who had vacationed on Tioman Island between June and August 2011. The Ministry of Health, Malaysia (MOH) in collaboration with the Department of Veterinary Services, Malaysia (DVS) conducted a cross sectional study in November 2011 to determine the presence of Sarcocystosis among humans, animals and in the environment in Tioman Island. Epidemiological investigations conducted involved a community health survey of 44 residents in Kampung Salang, Tioman and review of outpatient attendance cards for suspected or confirmed cases of Sarcocystosis. Twenty-eight fresh stool samples were collected and sent to the National Public Health Laboratory (NPHL) for detection of Sarcocystis oocysts using fluorescence microscopy. Water samples taken from 27 water sampling points around the island were processed and analysed under the fluorescence microscope using ultraviolet (UV) light at the Institute for Medical Research (IMR) to detect the presence of Sarcocystis sporocyst. DVS collected 84 faecal samples from four types of domesticated animals and then analysed them at the Veterinary Services Centre in Tioman Island for Sarcocystis oocysts and other parasitic ova and cysts using qualitative Floatation Technique. The results showed that Sarcocystis was not present in humans, animals and in the environment in Tioman Island during the study period. Further surveillance among humans, wildlife and the environment is needed to determine Sarcocystis endemicity in Tioman Island.

Temporomandibular disorders in patients with mandibular fractures: a preliminary comparative case-control study between South Australia and Oman.

The status of temporomandibular disorders (TMD) in subjects with previously treated mandibular fracture was evaluated in two centres: South Australia (SA) and Oman (O). TMD status was evaluated using Mandibular Function Impairment Questionnaire (MFIQ), Helkimo index for clinical dysfunction (HI), RDC/TMD and Wilkes' classification. Data were retrieved for adult patients treated for mandibular fracture over 3 years from January 2004 to December 2006. Thirty-six subjects participated from SA and 23 from O. Their results were compared with matched controls. The incidence of TMD symptoms in SA injured and control groups was higher compared with the O groups. There was statistically significant difference on all evaluation indices for SA injured subjects compared with controls (MFIQ/P 0.04, HI/P 0.0015, RDC/TMD/P 0.05, Wilkes classification/P 0.03). These TMD symptoms were clinically insignificant for most subjects and all were internal derangement of the temporomandibular joint (TMJ). There was no significant difference in all evaluation indices for O injured subjects compared with controls. For SA injured subjects who reported clinically significant TMD symptoms, assault and bilateral mandibular fractures were predominant features. The study shows that most mandibular injuries fully recover and the associated TMJ trauma usually has low clinical significance in the long term.
