Abstract
Declarations of exclusive publication, author contribution, conflict-of-interest and copyright transfer are important formalities required by most biomedical journals. Conflict-of-interest may be personal, commercial, political, academic or financial. It is particularly important for authors to provide a full and complete disclosure of any financial relationship with a commercial organisation that may have an interest in the contents of the submitted manuscript. Editors, editorial board members and reviewers should also declare any possible conflicts-of-interest. The handling of conflict-of-interest during manuscript preparation, peer review and editorial decision making impacts the credibility of published articles and scientific research in general.

Abstract
A book review is a form of academic writing that provides a succinct yet critical analysis evaluating the content, style, merit and significance of a book. The reader should gain insight into the strengths and weaknesses of the book, aided by input from the reviewer. The four stages of writing a book review are: introducing the book, outlining its contents, highlighting parts of the book by selecting particular chapters or themes, and giving a detailed evaluation.

Abstract
Background Squamous odontogenic tumor (SOT) is a rare benign odontogenic epithelial neoplasm. A slow-growing painless expansive swelling is the common presenting symptom. Histopathologically, SOT can be easily misdiagnosed as an acanthomatous ameloblastoma. Although Notch receptors and ligands have been shown to play a role in cell fate decisions in ameloblastomas, the role of these cell signaling molecules in SOT is unknown. Case report This paper describes a case of SOT affecting the anterior mandible of a 10-year-old Indian female. The patient was treated by local surgical excision and there has been no follow-up clinical record of recurrence 5 years after primary treatment. Histopathological examination revealed a solid, locally-infiltrative neoplasm composed of bland-looking squamatoid islands scattered in a mature fibrous connective tissue stroma and the diagnosis was SOT. Immunohistochemical evaluation showed positive reactivity of varying intensity in the neoplastic epithelial cells for Notch1, Notch3, Notch4, and their ligands Jagged1 and Delta1. Expression patterns showed considerable overlap. No immunoreactivity was detected for Notch2 and Jagged2. Conclusions Present findings suggest that Notch receptors and their ligands play differential roles in the cytodifferentiation of SOT.

Abstract
Alterations in the balance of matrix metalloproteinase to tissue inhibitor of metalloproteinase (TIMP) are seen after acute myocardial infarction (AMI) and are associated with adverse left ventricular remodeling and prognosis in this setting. We aimed to investigate the association between TIMP levels and the occurrence of major adverse cardiac events (MACEs) after AMI. We measured plasma TIMP-1, -2, and -4 levels in 1,313 patients presenting with AMI. Subjects were followed over a median period of 520 days for the occurrence of MACEs. Clinical risk was assessed using the Global Registry of Acute Coronary Events (GRACE) score. All TIMP levels correlated with patient age and inversely with estimated glomerular filtration rate (all p values <0.001). Levels were higher in women versus men (p <0.001) and in subjects with a history of diabetes (TIMP-1, p <0.001; TIMP-2, p = 0.002; TIMP-4, p <0.001) or hypertension (TIMP-1, p = 0.031; TIMP-2, p <0.001; TIMP-4, p <0.001). TIMP-1 and TIMP-4 were higher in subjects with previous MI or angina (p <0.001). TIMP levels increased incrementally with quartiles of GRACE score (p <0.001). All TIMPs showed univariate association with the occurrence of MACEs (p <0.001). Areas under the receiver operator characteristic curve for prediction of MACE at 1 year were 0.61 for TIMP-1, 0.57 for TIMP-2, and 0.64 for TIMP-4. Combination of TIMPs with GRACE risk score revealed a greater area under the curve than GRACE score alone (0.72 vs 0.69, p = 0.0015). On multivariable Cox proportional hazards analysis, GRACE score (p <0.001) and plasma TIMPs (log TIMP-1, p = 0.017; log TIMP-2, p <0.001; log TIMP-4, p = 0.011) independently predicted MACEs. Using Kaplan-Meier analysis, the risk of MACEs increased incrementally with the number of TIMPs above their respective median (p <0.001 for all comparisons, log-rank test). In conclusion, higher plasma TIMP-1, -2, and -4 after AMI are associated with MACEs and provide additional prognostic information to that obtained from GRACE clinical risk scores alone.

Abstract
An editorial may be written by the editor or someone invited by the editor. It serves many other purposes, including critiques of original articles published in the same issue of the journal, concise reviews of topics that do not warrant a full-length invited review, and other topics on very recent developments that are deemed by the editor to be important to readers of the journal and the community. As there is typically a limited space in which to deliver its contents, the message contained in the editorial needs to be well thought out and concisely delivered. It should contain the correct sequence of the elements of critical argument, ideally supported by evidence, and end with a clear conclusion.

Abstract
INTRODUCTION Evidence from randomised controlled trials has shown that laparoscopic colon and rectal cancer resection not only confers short-term benefits but also does not differ considerably in terms of its long-term oncological outcomes, as compared with open surgery. METHODS All laparoscopic colon and rectal resections performed between January 2005 and December 2007 were included. Patient records were reviewed from a prospective database and the relevant clinical data was obtained, with a subgroup analysis of cancer procedures performed. RESULTS 418 patients (247 male), median age 63 years (range 24 to 88), underwent laparoscopic resection of the colon and rectum. The median Body Mass Index (BMI) was 22.5 (range 13.5 to 39.3). The majority of the procedures were performed for malignant disease (81.3 percent) and the most common procedure was anterior resection (79.4 percent). The median duration of surgery was 135 minutes (range 65 to 330), with conversions to open surgery in 44 patients (10.5 percent). Complications occurred in 78 patients (18.7 percent), including anastomotic leaks in five (1.20 percent). The median length of hospital stay was five days (range 3 to 90) and the median follow-up was 19 months (range 1 to 46). In the 340 patients with malignant disease, the median number of lymph nodes harvested was 13 (range 5 to 48), and at the latest review, 230 patients (67.6 percent) were disease-free, with locoregional recurrence in 2.9 percent and systemic recurrence in 10 percent. CONCLUSION To date, this is the largest series of laparoscopic colorectal resections reported locally, and our results show that it is safe, feasible and produces favourable results.

Abstract
BACKGROUND Published data has confirmed the oncological safety and efficacy of laparoscopic colorectal surgery. Continued surgical innovation has seen the recent resurgence of single-port laparoscopic surgery. We present a series of 10 cases of single-incision laparoscopic surgery (SILS) for right hemicolectomy, with the aim of reaffirming the feasibility and favourable short-term results of this technique. METHODS Ten patients underwent SILS for right hemicolectomy using the SILS port, between June 2009 and August 2009. A longitudinal periumbilical incision was used as the access point for all cases. Data analysed included age, gender, American Society of Anaesthesiology score, body mass index (BMI), location of disease, duration of surgery, length of incision and duration of hospital stay. Inclusion criteria were no prior abdominal surgery, no intra-abdominal sepsis, no distant metastases and a BMI of <30. RESULTS All 10 cases of right hemicolectomy were successfully performed using the SILS port through a single periumbilical incision. The median age of patients was 64 years (range 48-83 years), with a median body mass index of 21.5 kg/m(2) (range 18.9-25.6 kg/m(2)). The median duration of surgery and hospital stay was 83 min (range 60-125 min) and 6 days (range 5-11 days), respectively. No morbidity or mortality was associated with this technique, and all patients recovered uneventfully. CONCLUSION This case series illustrates that SILS for right hemicolectomy is feasible and safe. However, the routine use of this innovative technique in malignant disease cannot be recommended without further large-scale prospective trials.

Abstract
Computed tomography (CT) has been recognised as the most widely used imaging technique in both adults and children, owing to technological developments, especially with the recent innovations in multislice CT. This has resulted in an increase in the use of CT examinations in children younger than 15 years of age in developed countries. The increasing use of paediatric CT in clinical practice has raised concerns regarding the potential risk of radiation-induced malignancy. This is because CT examinations deliver a much higher radiation dose than conventional radiographic techniques. Children are more sensitive to radiation exposure than adults and have a longer time ahead of them to manifest radiation-induced effects and injuries. Therefore, it is of paramount importance to reduce or minimise the radiation dose to children when choosing CT as the major imaging modality for diagnostic purposes. This article reviews the clinical applications of paediatric CT with regard to the adjustment of imaging protocols in routine clinical practice and in the emergency department, the justification of CT use in paediatric imaging, clinical awareness of CT-associated radiation risk and strategies to minimise radiation exposure to children.

Abstract
Evidence-based medicine (EBM) aims to combine the best available scientific evidence with clinical experience and individual judgment of patient needs. In the hierarchy of scientific evidence, systematic reviews (along with meta-analyses) occupy the highest levels in terms of the quality of evidence. A systematic review is the process of searching, selecting, appraising, synthesising and reporting clinical evidence on a particular question or topic. It is currently considered the best, least biased and most rational way to organise, gather, evaluate and integrate scientific evidence from the rapidly-changing medical and healthcare literature. Systematic reviews could be used to present current concepts or serve as review articles and replace the traditional expert opinion or narrative review. This article explains the structure and content of a systematic review.

Abstract
With the introduction of 64- or more-slice computed tomography (CT) technology, multislice CT angiography has been increasingly used as a non-invasive modality for the diagnosis of coronary artery disease. Despite its potential advantages and promising clinical results, multislice CT angiography suffers from high radiation dose which contributes to radiation-induced malignancy in patients undergoing cardiac CT examinations. This has raised serious concerns in clinical practice. A number of strategies have been recommended and implemented to reduce the radiation dose associated with multislice CT angiography in cardiac imaging. The aim of this review is to present an overview of the various approaches used for radiation dose reduction. Future directions of multislice CT angiography with regard to the judicious use of this promising technique and increased awareness of the radiation risk are highlighted.

Abstract
Multislice computed tomography (CT) angiography represents a technological evolution in cardiac imaging due to improved spatial and temporal resolution. Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a viable and effective alternative to invasive coronary angiography in selected patients. Multislice CT angiography has demonstrated high sensitivity and specificity, and in particular, a very high negative predictive value, which makes it a valuable imaging modality for screening patients suspected of coronary artery disease. In addition, multislice CT angiography demonstrates accuracy in the detection and characterisation of coronary plaques, and it has been reported to play an important role in predicting disease progression and cardiac events. The aim of this review was to present an overview of the clinical applications of multislice CT angiography in coronary artery disease, with regard to its diagnostic accuracy and predictive value in coronary artery disease. Emerging areas of multislice CT, including dual-energy CT and CT myocardial perfusion, are also discussed. Limitations of multislice CT angiography and future directions of cardiac multislice CT are highlighted.

Abstract
The purpose of this report is to document a case of unsuspected ameloblastoma involving the right man dibular subpontic region in a 38-year-old Cambodian female patient. This lesion was purportedly preceded by multiple radiolucencies which were diagnosed as radi cular cysts and treated a few times in the past years by enucleation followed by endodontic therapy of the affected teeth. Bridgework restoration of the partially edentulous area was performed. This case report de monstrates radiographic changes that occurred in the periods before and after the diagnosis of amelo blas to ma. The case may represent an example of radicular cysts and ameloblastoma occurring as a collision phenomenon, or the ameloblastoma may have arisen as a result of neoplastic transformation of the lining epi thelium in an inflammatory odontogenic epithelial cyst.

Abstract
Computed tomography (CT) is currently a widely available imaging technique in clinical practice. Technical developments of CT imaging, especially the emergence of multislice CT, with increased scanning speed and volume as well as higher spatial and temporal resolution, have significantly enhanced the diagnostic value of CT in many clinical applications. CT has become an important diagnostic imaging modality in the emergency department, with high diagnostic accuracy and efficacy in both traumatic and non-traumatic conditions. There is, however, a growing concern about the risk of associated radiation exposure in the population exposed to CT examination. Justification of the application of CT is one of the main principles that physicians need to be aware of when choosing CT as the first-line technique for diagnosis. This article reviews the clinical applications of CT imaging in the emergency department, with a focus on patients presenting with headache, repeat and multiple CT imaging and whole body screening for trauma patients, and explores whether the applications are clinically justified.

Abstract
It is useful for authors to learn to deal with returned manuscripts with a rejection decision or a request for revision. Common reasons for rejection include contents outside the scope of the journal or inappropriate for the journal, incomplete submission, poor methodology, faulty experimental design, major flaws in the interpretation of results, extremely poor writing, and duplicated or plagiarised work. Authors should use the editor's and reviewers' comments to improve their manuscripts and resubmit elsewhere. Common reasons for revision requests include minor faults in the methodology, minor inaccuracies in data, inconsistencies among different sections of the manuscript, faulty deductions, data that do not support the conclusions, excessive data or text, poor or excessive illustrations, and poor but salvageable writing. A request for revision should be viewed positively, as it means that there is a possibility that the manuscript may still be potentially publishable, provided that all the editor's and reviewers' comments are addressed.

Abstract
A simple sphere test phantom has been developed for routine performance testing of SPECT systems in situations where expensive commercial phantoms may not be available. The phantom was based on a design with six universal syringe hubs set in the frame to support a circular array of six glass blown spheres of different sizes. The frame was then placed into a water-filled CT abdomen phantom and scanned with a triple head camera system (Philips IRIX, USA). Comparison was made with a commercially available phantom (Deluxe Jaszczak phantom). Whereas the commercial phantom demonstrates cold spot resolution, an important advantage of the sphere test phantom was that hot spot resolution could be easily measured using almost half (370MBq) of the activity recommended for use in the commercial phantom. Results showed that the contrast increased non-linearly with sphere volume and radionuclide concentration. The phantom was found to be suitable as an inexpensive option for daily performance tests.

Abstract
The manuscript reviewer is a key player in the manuscript processing system and journal publication process. The peer review system is an important component of modern scientific publishing, and is a great help to editors in deciding whether or not a submitted manuscript is suitable for publication. The reviewer's responsibilities include protecting the integrity of his or her speciality or subspecialty, the reputation of the scientific journal, and the welfare of human and animal subjects, as well as treating the author's manuscript with respect, fairness and impartiality. The manuscript review should ideally be done in a systemic manner, with components comprising a brief summary and a tabulation of the manuscript analysis under the major headings of strengths, weaknesses, general comments and specific comments.
