Bone graft is essential in various orthopaedic procedures. Among the many donor sites for harvesting autologous bone graft, the iliac crest has been the most commonly used. However, for foot and ankle procedures the proximal tibia has gained popularity as an alternative donor site due to its anatomic proximity to the primary surgical site. In this article we evaluated the possible complications associated with harvesting proximal tibia bone graft. Our study showed the low incidence of morbidity in harvesting proximal tibia bone graft, thereby providing a good alternative donor for foot and ankle procedures.

Extracranial aneurysms are a rare presentation accounting for only less than 5% of all peripheral artery aneurysms. The left common carotid artery aneurysm is considered even rarer. We present a case of a 46-year-old gentleman who presented to casualty unit with a neck mass, stridor and acute respiratory distress. Prior to this admission patient was being investigated for Takayasu arteritis (TA). Patient was subsequently intubated due to respiratory compromise. A CT angiography of the thorax was done showed a proximal left common carotid artery aneurysm with contained leakage of aneurysm with severe compression of the trachea. Patient was subsequently transferred to the vascular team in National Heart Institute for further management.

We present the case of a patient with multiple atraumatic osteoporotic vertebral fractures in an adolescent with suprasellar germinoma and also review of relevant literature. The patient suffered from a rare adolescent brain tumour with common complications which are often overlooked and give rise to significant morbidity. Suprasellar germinoma is an intracranial neoplasm, that in addition to its rarity, has variable clinical presentation. Despite appropriate treatment and good outcome, tumour related morbidity is still of concern for these patients.

Osteosarcoma is a primary malignant neoplasm of the bone. Osteosarcoma of the jaws especially those of maxilla is rare. The diagnosis of osteosarcomas is diff icult and challenging. In this case report we highlight a rare case of osteosarcoma of the maxilla in a 29 year old male patient which was highly aggressive and was initially diagnosed as rhabdomyosarcoma. This case highlights the difficulty in diagnosing osteosarcoma merely from incisional biopsy specimens which may not be representative of the whole tumour. Limited clinical information at incisional biopsy also adds to the difficulty in arriving at the definitive diagnosis. We further discuss the treatment modalities followed in this case.

Introduction: Specialists constitute a major ‘driving force’ and catalyst for growth of research in their speciality. A clearer understanding is required as to what motivates their participation in research as well as the barriers they faced. This research aims to study the attitudes, barriers and facilitators faced by specialists and to identify strategies to promote and sustain research activities in their hospitals. Methodology: A cross-sectional survey using selfadministered questionnaires was conducted among all specialists working in government specialist hospitals in the northern states of Malaysia. Results: Out of 733 questionnaires distributed, 467 were returned giving a response rate of 63.7%. Ninety-nine percent of the respondents believed that research benefits patients while 93.3% think research helps in their professional development. However, 34.8% think that under their present working conditions, it is unlikely they will participate in research. The major barriers identified were lack of funds for research (81%); lack access to expertise, software or statistical analysis (78.4%); interference with daily work schedule (75.1%) and inconsistent manpower in their department (74.2%). There are three barriers with statistically significant difference between hospitals with CRC compared to hospitals without CRC; lack of funds, mentors and access to expertise, software or statistical analysis. The demographic factors, attitudes and barriers contributing to involvement in research also investigated. The main facilitators for the conduct of research are potential to benefit patients and potential for professional development. Conclusion: Taking note of the findings, the Ministry of Health can implement appropriate strategies to improve specialist participation in research.

Background: MDM2 and p53 are involved in a negative feedback loop where p53 regulates MDM2 at the transcriptional level. MDM2, in turn, downregulates p53. This co-ordinated interaction between these proteins is set to play an important role in the regulation of cell cycle progression following DNA damage to cells. The over-expression of both p53 and MDM2 has been reported in various cancers. However there are only few studies discussing the co-expression of MDM2 with p53 in oral squamous cell carcinoma Aim: The purpose of this study was to determine the correlation of co-expression of p53, MDM2, and Ki-67 proteins with clinico-pathological factors in oral squamous cell carcinoma (OSCC) and to conduct a systematic review of the co-expression of p53/MDM2. Method: This is a retrospective descriptive study and a systematic review. Formalin-fixed paraff inembedded tissues from 45 OSCC cases were stained by immunohistochemistry (IHC) for p53, MDM2, and Ki-67 proteins. Results: Immuno-reactivity for p53, MDM2, and Ki-67 was seen in 75.6%, 97.8%, and 62.2% cases of OSCC respectively. The co-expression of p53 and MDM2 (p53/MDM2) was detected in 97.1%, however there was no signif icant correlation between p53 and MDM2 expression. Notably, p53/MDM2 coexpression was significantly associated with tumour differentiation (p-value = 0.045). The Ki-67LI was not signif icantly associated with neither MDM2 nor p53/MDM2 co-expression (p-value = 0.268, 0.916 respectively). Conclusion: The expression of MDM2 was not signif icantly associated with p53 expression suggesting that MDM2 expression is mediated by p53-independent pathways or mutated p53 could not induce the expression of MDM2 in this set of OSCCs. The only clinico-pathological parameter that correlates significantly with co-expression of p53/MDM2 is tumour differentiation where it is suggestive that the co-expression of these 2 proteins is indicative of aggressive tumour behavior.

To discuss the unique relationship between psychosis and seizures in a young individual, who is also pregnant. Psychosis of epilepsy can present in multitude of ways, including pre-ictal, ictal, post-ictal, chronic interictal, and forced normalization psychosis.
