    In this work, a non-abelian metabelian group is represented by G while represents conjugacy class graph. Conjugacy class graph of a group is that graph associated with the conjugacy classes of the group. Its vertices are the non-central conjugacy classes of the group, and two distinct vertices are joined by an edge if their cardinalities are not coprime. A group is referred to as metabelian if there exits an abelian normal subgroup in which the factor group is also abelian. It has been proven earlier that 25 non-abelian metabelian groups which have order less than 24, which are considered in this work, exist. In this article, the conjugacy class graphs of non-abelian metabelian groups of order less than 24 are determined as well as examples of some finite groups associated to other graphs are given.

    A domination polynomial is a type of graph polynomial in which its coefficients represent the number of dominating sets in the graph. There are many researches being done on the domination polynomial of some common types of graphs but not yet for graphs associated to finite groups. Two types of graphs associated to finite groups are the conjugate graph and the conjugacy class graph. A graph of a group G is called a conjugate graph if the vertices are non-central elements of G and two distinct vertices are adjacent if they are conjugate to each other. Meanwhile, a conjugacy class graph of a group G is a graph in which its vertices are the non-central conjugacy classes of G and two distinct vertices are connected if and only if their class cardinalities are not coprime. The conjugate and conjugacy class graph of dihedral groups can be expressed generally as a union of complete graphs on some vertices. In this paper, the domination polynomials are computed for the conjugate and conjugacy class graphs of the dihedral groups.

    BACKGROUND: The parapharyngeal tumour is a rare case of head and neck tumour. Benign and malignant tumours can arise from any of the structures contained within the parapharyngeal space. Pleomorphic adenoma is the most typical salivary gland tumour that is found in this space and surgical resection is the main treatment for this tumour. Since the modern era of the medicine, different kinds of diagnostic imaging and surgical approaches have been introduced to evaluate this tumour.

    CASE PRESENTATION: We present a case report of a parapharyngeal space mass that was found to be pleomorphic adenoma of minor salivary gland, their clinical presentation, radiological imaging and literature review of the transoral surgical approaches for parapharyngeal tumour.

    DISCUSSION AND CONCLUSION: The transoral approach remains one of the classical and effective methods for the resection of the benign prestyloid parapharyngeal tumour. The surgeons need to have a good knowledge of diagnostic imaging and surgical techniques to determine which surgical procedure is the best for the patients in order to eradicate the diseases and minimize the complications ultimately.

    The year 2005 marked the rebirth of JUMMEC when the Editorial Board took over from its previous Editor with modest but realistic expectations. One year on, we have successfully achieved our initial expectation, that is, to encourage greater participation from our junior academics to write and publish in our very own journal, JUMMEC. As we head towards the end of 2006 and prepare to usher in 2007, we see JUMMEC consolidating and gaining in strength. Let us reflect on its past achievements and our expectations for the future.(Copied from article).

    Assault injury can occur to any parts of the body. Usually the target area is the head, neck, chest and abdomen as they contain many major structures that are vital for life. However, movement of the victim few seconds before the instrument reach the body can redirect the impact to the less fatal part of the body. The outcome may be less fatal but can lead to cosmetically unacceptable condition. (Copied form article).

    118 cases of cervical dysplasia were followed up by cytological smears for over 9 years to determine their biologic outcome. All grades of dysplasia showed evidence of regression and progression to more severe lesions, including carcinoma. Severe dysplasia however did not regress to normalcy and had the maximum conversion rates to malignancy. The period taken for transition to malignancy was found to be shorter than that generally described. Since even mild dysplasia carries with it a malignant potential, all patients with cervical dysplasia, irrespective of the grade, have to be followed up by repeated clinical and cytological examinations.

    In human sperm motility analysis, sperm segmentation plays an important role to determine the location of multiple sperms. To ensure an improved segmentation result, the Laplacian of Gaussian filter is implemented as a kernel in a pre-processing step before applying the image segmentation process to automatically segment and detect human spermatozoa. This study proposes an intersecting cortical model (ICM), which was derived from several visual cortex models, to segment the sperm head region. However, the proposed method suffered from parameter selection; thus, the ICM network is optimised using particle swarm optimization where feature mutual information is introduced as the new fitness function. The final results showed that the proposed method is more accurate and robust than four state-of-the-art segmentation methods. The proposed method resulted in rates of 98.14%, 98.82%, 86.46% and 99.81% in accuracy, sensitivity, specificity and precision, respectively, after testing with 1200 sperms. The proposed algorithm is expected to be implemented in analysing sperm motility because of the robustness and capability of this algorithm.

    Isolated apophyseal avulsion of the greater trochanter is a rare condition in the paediatric population, frequently related to avascular necrosis of the femoral head. Since there are few cases in the literature, there is no consensus regarding the best treatment of this injury. Our study describes the case of a 9-year-old patient with an avulsion of the right greater trochanter. A minimally invasive osteosynthesis was performed, achieving complete clinical and radiographic healing of the patient and no long-term complications after four years.

    OBJECTIVE: This study aims to examine the ability of optical coherence tomography (OCT) to differentiate ex vivo epithelial structure of benign disorders, dysplastic, and oral squamous cell carcinoma (OSCC) in comparison with the structure of normal marginal mucosa of oral biopsies. As a secondary objective, we examined the inter- and intra-observer variations of OCT measurements of two calibrated assessors.

    MATERIALS AND METHODS: Oral biopsies (n = 44) were scanned using the swept source OCT (SSOCT) and grouped by pathology diagnosis to benign, dysplasia or carcinoma. Two trained and calibrated assessors scored on the five OCT variables: thickness of keratin layer (KL), epithelial layer (EL), homogeneity of lamina propria (LP), basement membrane integrity (BMI), and the degree of reflection of the epithelial layer (Ep Re). Chi-square tests and Fischer's exact method were used to compare the data.

    RESULTS: The OCT images showed breached BM status in all the OSCC samples (100%). Epithelial reflection was noted to be hyper-reflective in all the OSCC and oral dysplasia samples (100%). An increase in KL in 66.67% of the OSCC and 100% of the oral dysplasia samples was found. EL was increased in all the OSCC samples (100%) and 85.72% of the oral dysplasias. Kappa values showed that there was very good agreement (over 0.7) when scoring individual parameters between the two assessors.

    CONCLUSION: The study showed that the BM status was a key parameter in the detection of SCC and for differentiating SCC from oral dysplasia or benign disorders.

    CLINICAL RELEVANCE: OCT is a non-invasive and non-radioactive adjunct diagnostic tool that can provide immediate results on the structure of oral mucosa. The BM status measured ex vivo was a key parameter in the detection of SCC and for differentiating SCC from oral dysplasia or benign disorders.

    Acute traumatic transphyseal fracture of the capital femoral epiphysis is a rare but serious injury. The injury is typically inflicted by a severe trauma. Because of the vulnerability and predisposed anatomy of the femoral epiphysis in relation to its blood supply, the fracture has been designated to have poor prognosis with inevitable osteonecrosis and eventual deformity of the hip. We report a case of such fracture in a 13-year-old child in view to highlight some of the anticipated problems in the management of such injury.

    Schwannomas are benign tumors. A series of three unusual cases involving the head and neck region at the Department of ENT, Hospital Ipoh from July 2004 to June 2005 is presented. The first case was a pedunculated schwannoma of the tongue base. The second was a schwannoma of the cervical sympathetic chain who developed a transient Horner's Syndrome upon fine needle aspiration cytology. The third case was a bilobed cervical vagal schwannoma which developed immediate vocal cord palsy postoperatively which was evident at six months follow-up. All tumors were removed surgically.

    Head and neck cancer (HNC) is a disease of the upper aerodigestive tract and is one of the most frequently diagnosed cancers worldwide. A high rate of cancers involving the head and neck are reported across the Asian region, with notable variations between countries. Disease prognosis is largely dependent on tumor stage and site. Patients with early stage disease have a 60-95% chance of cure with local therapy. Early diagnosis and appropriate treatment are important to increase the likelihood of cure and survival. However, the majority of patients present with locally advanced disease and require multimodality treatment. This necessitates, a multidisciplinary approach which is essential to make appropriate treatment decisions, particularly with regards to tolerability, costs, available infrastructure and quality of life issues. Unfortunately, majority of the studies that dictate current practice have been developed in the west where diseases biology, patient population and available infrastructure are very different from those in the Asian continent. With this in mind an expert panel of Head and Neck Oncologists was convened in May 2012 to review the National Comprehensive Cancer Network (NCCN) and the European Society for Medical Oncology (ESMO) clinical practice guidelines and develop practical recommendations on the applicability of these guidelines on the management of head and neck cancer for Asian patients. The objective of this review and consensus meeting was to suggest revisions, to account for potential differences in demographics and resources, to the NCCN and ESMO guidelines, to better reflect current clinical management of head and neck cancer within the Asian region for health care providers. These recommendations, which reflect best clinical practice within Asia, are expected to benefit practitioners when making decisions regarding optimal treatment strategies for their patients.

    Penetrating injury to the head is considered a form of severe traumatic brain injury. Although uncommon, most neurosurgical centres would have experienced treating patients with such an injury. Despite the presence of well written guidelines for managing these cases, surgical treatment requires an individualized approach tailored to the situation at hand. We describe a collection of three cases of non-missile penetrating head injury which were managed in two main Neurosurgical centres within Malaysia and the unique management approaches for each of these cases.

    A neck mass with soft consistency suggests the diagnosis of a cyst which is usually congenital in origin. Needle aspiration yielding blood should alert the physician the possibility of hemangioma although it is very rare. Ultrasonography and computed tomography will delineate the extent and nature of the lesion and provide the roadmap for surgical excision. We report a case of a girl who presented with a painless neck mass which was later found to be a hemangioma originating from the sternohyoid muscle. The morphology and immunohistochemical stain were consistent with hemangioma.
