Sample size estimation and sampling techniques for selecting a representative sample
Aamir Omair
October-December 2014, 2(4):142-147
Introduction: The purpose of this article is to provide a general understanding of the concepts of sampling as applied to health-related research. Sample Size Estimation: It is important to select a representative sample in quantitative research in order to be able to generalize the results to the target population. The sample should be of the required sample size and must be selected using an appropriate probability sampling technique. There are many hidden biases which can adversely affect the outcome of the study. Important factors to consider for estimating the sample size include the size of the study population, confidence level, expected proportion of the outcome variable (for categorical variables)/standard deviation of the outcome variable (for numerical variables), and the required precision (margin of accuracy) from the study. The more the precision required, the greater is the required sample size. Sampling Techniques: The probability sampling techniques applied for health related research include simple random sampling, systematic random sampling, stratified random sampling, cluster sampling, and multistage sampling. These are more recommended than the nonprobability sampling techniques, because the results of the study can be generalized to the target population.

Segmented and sectional orthodontic technique: Review and case report
Tarek El-Bialy
May-August 2013, 1(2):90-96
Friction in orthodontics has been blamed for many orthodontic-related problems in the literature. Much research as well as research and development by numerous companies have attempted to minimize friction in orthodontics. The aim of the present study was to critically review friction in orthodontics and present frictionless mechanics as well as differentiate between segmented arch mechanics (frictionless technique) as compared to sectional arch mechanics. Comparison of the two techniques will be presented and cases treated by either technique are presented and critically reviewed regarding treatment outcome and anchorage preservation/loss.

An overview of nursing in Saudi Arabia
Mansour Saleh AlYami, Roger Watson
January-March 2014, 2(1):10-12
Achieving and maintaining a stable nursing workforce is an important issue for the well-being of the rapidly growing population of Saudi Arabia. However, high turnover of expatriate staff and low recruitment of Saudi nationals have led to a serious staff shortage in the professions, particularly of well-qualified and experienced nurses. Nursing leaders need to work to improve the image of nurses and facilitate the recruitment of women into the nursing profession. Reduced working hours and part-time contracts with increased salaries and benefits could attract more young women to the profession, as might the provision of facilities such as private transportation and on-site childcare. Furthermore, establishing a national association for nurses would advance the nursing profession and help to ensure that all nurses undertake fully comprehensive training before entering the workforce.

Design of ultra-stable insulin analogues for the developing world
Michael A Weiss
May-August 2013, 1(2):59-70
The engineering of insulin analogues illustrates the application of structure-based protein design to clinical medicine. Such design has traditionally been based on structures of wild-type insulin hexamers in an effort to optimize the pharmacokinetic (PK) and pharmacodynamic properties of the hormone. Rapid-acting insulin analogues (in chronological order of their clinical introduction, Humalog ® [Eli Lilly & Co.], Novolog ® [Novo-Nordisk], and Apidra ® [Sanofi-Aventis]) exploit the targeted destabilization of subunit interfaces to facilitate capillary absorption. Conversely, long-acting insulin analogues exploit the stability of the insulin hexamer and its higher-order self-assembly within the subcutaneous depot to enhance basal glycemic control. Current products either operate through isoelectric precipitation (insulin glargine, the active component of Lantus ® ; Sanofi-Aventis) or employ an albumin-binding acyl tether (insulin detemir, the active component of Levemir ® ; Novo-Nordisk). Such molecular engineering has often encountered a trade-off between PK goals and product stability. Given the global dimensions of the diabetes pandemic and complexity of an associated cold chain of insulin distribution, we envisage that concurrent engineering of ultra-stable protein analogue formulations would benefit the developing world, especially for patients exposed to high temperatures with inconsistent access to refrigeration. We review the principal mechanisms of insulin degradation above room temperature and novel molecular approaches toward the design of ultra-stable rapid-acting and basal formulations.

Strategic approaches to simulation-based education: A case study from Australia
Debra Nestel, Marcus O Watson, Margaret L Bearman, Tracy Morrison, Shane A Pritchard, Pamela B Andreatta
January-April 2013, 1(1):4-12
This paper addresses some of the challenges met when developing widely distributed, broad spectrum, simulation-based education (SBE) for health professionals, such as resource duplication, inconsistent facilities utilization, discipline-specific silos, and the intersection of academic institutions and health services sectors. We examine three primary contributors to successful simulation-based practices - strategic planning, program development, and professional networks. Further, we provide examples of how each of these contributors function at different levels to assure comprehensive, yet sustainable approaches to implementing SBE for greatest impact at national, state, regional, and institutional levels. We draw on the example of Australia and its state and regional government structures, including the challenges in providing health services across a widely variable geography and population distribution. The types of health services and issues relating to health provision and management reflect those found in many western countries. Our hope is that the experiences gained at each level of governance within Australia may inform similar, successful development in other countries. We emphasize the importance of leadership and investment at the national level that serves to inform state, regional, and institutional efforts through a "trickle down" effect. Although evaluation of the strategic planning, program development, and professional networks described in this case study is still ongoing, their preliminary coordination has resulted in significant investment and support at all levels.

Palliative management of intractable hiccups in a patient with an advanced brain tumour
Sami Ayed Alshammary, Balaji P Duraisamy, Lobna M. A. Saleem, Luma Al Fraihat, Abdullah Altamimi, Stuart Brown
October-December 2016, 4(4):294-296
Intractable hiccupping is distressing for both patients under palliative care and their families, particularly if the patients have advanced cancer. The lack of clear management guidelines renders hiccup management challenging for health professionals. We report our management of intractable hiccups in a 70-year-old man with a progressive malignant brain tumour who was under palliative care. The hiccups were difficult to control; several drugs were tested before we finally introduced (and upwardly titrated) gabapentin, which appears to be safe when used to manage intractable hiccups.

Nursing research in the 21 st century
Roger Watson
January-April 2013, 1(1):13-18
Aim: To explore the development of nursing research and provide some examples of research relevant to clinical practice. Background: Nursing research developed in the last century as did nursing theories and models. However, nursing research does not have the same high profile as, for example, medical research and has tended to lag behind medical, and other forms of research, in terms of funding and in the apparent impact it has on clinical practice. Design: Discussion paper. Methods: Using a popular nursing model based on activities of daily living, nursing research that is relevant to these activities of daily living is explored and exemplified using a few key examples. Some of these examples are historical and some are current. Conclusion: Nursing research has developed greatly over the past century and continues to develop in the 21 st century. Nursing research is relevant to the needs of patients and has had an impact on clinical practice.

Sami Ayed Alshammary, Abdullah Alsuhail, Balaji P Duraisamy, Saad Hamad Alabdullateef, Savithiri Ratnapalan
April-June 2015, 3(2):61-66
Introduction: Palliative care is a multidisciplinary approach that aims to improve the quality of life of patients with life-threatening illnesses. It has been recognized as a crucial part of patient care in oncology. Palliative care service was established in the comprehensive cancer center of King Fahad Medical City (KFMC), Riyadh, Saudi Arabia in March 2010. The objective of this study was to determine the interval between the first palliative care consult (PCC1) and death, and explore the possible cause of suggestive short timeframe between PCC1 and death. Patients and Methods: This study included 210 cancer patients who had their PCC1 in KFMC within the period of March 2012 and March 2014. Demographic information, cancer diagnosis, date of cancer diagnosis, reason for referral, all symptoms reported in Palliative Care Unit, and date of death were gathered from the patients' charts. The interval between the PCC1 and death were computed and analyzed. Results: Of the 210 patients, 121 (57.6%) were female, 127 (60.5%) were <60 years old, and 190 (90.5%) had non-haematological tumours. The main reasons for referral were symptom control (62.4%), symptom control and end of life (EOL) care (12.4%), symptom control and transfer of care (11.4%), and EOL care (8.6%). The median interval between PCC1 and death, diagnosis to PCC1, and diagnosis to death intervals were 19, 212, and 360 days, respectively. Patients diagnosed with haematological tumours were referred relatively earlier to palliative care. The difference in the mean (haematology > non-haematology) for the interval between PCC1 and death was 146.2 days (P < 0.001). Conclusions: Late referrals to palliative care services KFMC is the strongest predictor of the short interval between PCC1 to death of advanced stage cancer patients. Identifying the potential cause of the late referrals can lead to developing optimal policies for the timely referral of cancer patients to palliative care upon diagnosis regardless of the stage of their disease. Education and advocacy are needed among the referring oncologists in the cancer center for earlier access to palliative care. Future studies are needed to establish the appropriate timing of the PCC1.

Continuing medical education in Saudi Arabia: Experiences and perception of participants
Mohammad A Alkhazim, Alaa Althubaiti
January-March 2014, 2(1):13-19
Introduction: Continuing medical education (CME) is important in developing competencies of medical practitioners with all the different influencing factors that have impact on their opinions and preferences. Despite the broad range of work on CME, very few studies have examined participants' opinions and attitudes towards CME. However, understanding them is critical in improving the practice of CME. Purpose: The purpose of this study was to explore attendees' perception of CME in Saudi Arabia regarding the different aspects of its practices and preferences. Materials and Methods: A survey composed of demographic questions, frequency of reading habits and 24 other related items was developed for CME participants. Participants were asked to indicate the extent to which they agreed or disagreed with each of the 24 items on a 5-point Likert scale. In total, 601 surveys were analysed. Results: The response to each item in the questionnaire was compared on the basis of demographic variables. The results showed that healthcare practitioners acknowledged the importance of CME in improving their knowledge, attitudes, clinical and academic skills, as well as improve their clinical practice outcome. Differences of opinion were categorised by gender, profession, nationality and age. Conclusion: The study showed that opinions related to CME varied among different disciplines and nationalities. Moreover, it raised questions related to the system of sponsoring participants to attend CME events and its consideration for ethical issues. There is a need to embed the concept of lifelong learning into the education of basic health professions. In addition, the policies related to sponsoring and accrediting CME in Saudi Arabia should be improved. We recommend further research into this matter.

The role legitimacy of nurses in Saudi Arabia
Ameera Mohammed Aldossary
January-April 2013, 1(1):28-37
Context: Nationally, there is no clear scope of practice for nurses working in Saudi Arabia identifying their role legitimacy as the Nursing Board in the Saudi Commission of Health Specialties has not yet formalized a scope of nursing practice. Role legitimacy can be identified either by a supervisory body or by an agreement that may exist among individual groups. Aims: This study aimed to identify nurses' role legitimacy in Saudi Arabia from the view of nurses, doctors, and patients. Settings and Design: A large survey was undertaken in 2008 in 10 hospitals located in the Eastern Province of Saudi Arabia related to three major healthcare sectors (government, military, private). Materials and Methods: A quota sample of nurses (n = 614, RR = 61.4%), doctors (n = 130, RR = 26.0%) and patients (n = 322, RR = 64.4%) was undertaken, utilizing a self-administered questionnaire that drew upon the King's Nurse Performance Scale. Statistical Analysis Used: A descriptive analysis was undertaken, using the Chi-square test to compare the views of the participants. Results: The domains of physical care, professional aspects and care management formed a major focus of the nurses' role, with no evidence of role legitimacy regarding the psychosocial and communication aspects of patient care. Conclusions: There was a traditional view of the nurses' role within acute care delivery which will need to be addressed if nurses are to contribute significantly to promoting the health of people in Saudi Arabia.

Selecting the appropriate study design for your research: Descriptive study designs
Aamir Omair
July-September 2015, 3(3):153-156
This article describes the importance of selecting the appropriate epidemiological study design for a given study question. It provides an explanation to the different terms used in describing study designs with regards to observational versus interventional and descriptive versus analytical types of study designs. This article focuses on the description of the different types of descriptive study designs, that is, case report, case series, correlational, and cross-sectional study designs. The requirements for selecting these study designs are discussed along with the advantages and disadvantages of each study design. The descriptive studies are similar in the context that they are based on a single sample with no comparative group within the study design. Their basic purpose is to describe the characteristics of the sample with regards to the characteristics that are present and so are useful in generating a hypothesis. The absence of a comparative group is the main limitation of the descriptive studies, and this is the reason they cannot be used to determine an association by testing a hypothesis showing a relationship between a risk factor and disease. The analytical study designs will be discussed in the next article in this series.

Assessment and modifications of digestion procedures to determine trace elements in urine of hypertensive and diabetes mellitus patients
Awad Abdalla Momen, Mohammed Awad Ali Khalid, Malik Abdalla Abdelrahman Elsheikh, Dafaalla Mohamed Hag Ali
September-December 2013, 1(3):122-128
Context: There is accumulating evidence that the metabolism of several trace elements like Cr, Cu, Pb, Cd, Co, Mn and Zn might have specific roles in the pathogenesis and progress of many diseases like hypertension (HTN) and diabetes mellitus (DM). Objectives: To provide a fast, efficient, sensitive, and reliable analytical procedure for trace element determination in urine samples of HTN and DM patients using inductively coupled plasma optical emission spectrometry (ICP-OES). Setting and Design: The ICP-OES operating conditions were optimised and carefully selected in order to maximise the sensitivity, precision and accuracy. Factors affecting analytical and biological variability of the concentrations under study were discussed and carefully optimised. Materials and Methods: Different digestion procedures with acids and oxidising reagents were tested. The suitable procedure ICP-OES was selected, carefully modified and applied. The validity and accuracy of the different elements were determined by spiking of samples with known amounts of multi-element standard solution. Statistical Analysis: Student t-test and analysis of variance (ANOVA) test were used for analysis. Microsoft Excel was used to assess the significance of the difference between variables. The concentrations obtained were expressed as mean value ± standard deviation (P = 0.05). Results: The results of this study showed that the mean concentrations of Cd, Zn, Pb, Cu, Cr and Mn in urine from both HTN (study group A) and DM (study group B) patients were higher than the corresponding values observed in the control group. However, while the mean value of Co was low as compared to the control group, the differences found were not significant (P = 0.05). Conclusion: The method used had excellent sensitivity, multi-element data could be obtained with very short acquisition time. The elements Cr, Cd, Pb and Zn might have specific roles in the pathogenesis and progress of HTN and DM. Further studies are required to investigate the possible roles of these elements in HTN and DM individuals.

Review of management of pruritus in palliative care
Sami Ayed Alshammary, Balaji P Duraisamy, Abdullah Alsuhail
January-March 2016, 4(1):17-23
Pruritus or itch is an uncommon symptom observed in palliative care, even more uncommon in cancer patients. However, if a patient experiences pruritus, the 'itch-scratch' cycle can damage the skin integrity and can increase the susceptibility of patients to infection owing to their frail immune system. The outcome can be very distressing, dramatically impacting the quality-of-life of the patient. Moreover, since severe pruritus seen in patients with advanced disease can be associated with failure of different organ systems, pruritus must be assessed based on the underlying organ systems and the pathophysiology involved. Regardless of the cause of pruritus, general skin care is important. Depending on the origin of pruritus, specific approach and medications must be considered. Caution must be taken during management of pruritus since most cancer patients take pain medications that interact with some antipruritic medications. In addition to the complex and unclear nature of cutaneous and central pathogenesis of pruritus, treatment of pruritus is challenging.

Risk factors of social anxiety in medical college students
Suneet Kumar Upadhyaya, Chintan M Raval, Devendra Kumar Sharma, Jaykaran Charan
July-September 2016, 4(3):207-211
Context: Literature suggests that social anxiety develops due to the complex interplay of multiple risk factors including self-perception and negative life events. We examined the association between these variables and social anxiety among medical students. Aims: The aim is to assess the association of risk factors and social anxiety in medical students. Materials and Methods: In this cross-sectional observational study, 334 medical students were given a semi-structured self-reported questionnaire. It enquired about demographic details: self-satisfaction in terms of weight, body image and facial appearance; six negative life events which were conflict between parents, sexual, physical and emotional abuse, family violence and loss of someone close. Social anxiety was assessed using Liebowitz social anxiety scale (LSAS). Data were analysed using SPSS software (Version 16.0., SPSS Inc., Chicago, IL, USA). Chi-square and Student's t-tests were used for qualitative and quantitative data, respectively. Linear regression analysis was performed to assess association between negative life events and social anxiety scores. The value of P < 0.05 was considered statistically significant. Results: Mean standard deviation (SD) age of sample was 18 (1.04) years. Mean (SD) LSAS score was 33 (20). Linear regression analysis adjusted for age, gender and family psychiatric history revealed positive association between LSAS score and dissatisfaction with body image (P = 0.001), dissatisfaction with facial appearance (P = 0.047), and family violence (P = 0.048). Dissatisfaction with weight showed association with social anxiety in univariate analysis, but it could not sustain on regression analysis. Other negative life events were not significantly associated with LSAS score. Conclusions: Development of social anxiety is significantly associated with dissatisfaction with body image and facial appearance. Exposure to family violence is also an associated factor.

The perfect MCQ exam
James Ware, Thuraya Essam Kattan, Imran Siddiqui, Ahmed M Mohammed
July-September 2014, 2(3):94-99
Aims: The Saudi Commission for Health Specialties' question banks for licensing international medical graduates and certifying Saudi trained residents are currently being upgraded. The process is briefly explained with the justification for the developments made to all the banks over the last 3 years. A process of quality assurance has been introduced to ensure the banks are maintained at the highest standards and procedures that are fit for purpose introduced for the management of test results. Results: An analysis of 16 undergraduate exams shows a sigmoid relationship between mean test scores (MTS) and numbers of functioning distractors. Sixteen computer-based Saudi Licencing Exam (SLE) banks were also analyzed to determine the mean MTS for all, 52.3 ± 7.88, which justifies the use of four option items and also validates the quality of the exams with a majority of items falling within the desired range of medium difficulty to obtain the highest reliability. Conclusion: The Saudi Commission believes that it is achieving increased quality in all aspects of test measurement and would hope that over the next 3 - 5 years achieve levels of excellence for all aspects of it licensing and certifying assessments.

Multiple intracranial lipoma
BP Venkatesh, Gaurav Malik, Manash Kumar Bora, Anand P Narasingam
April-June 2014, 2(2):78-81
Intracranial lipomas are rare congenital, non-neoplastic lesions discovered incidentally on computerised tomography (CT) or magnetic resonance imaging (MRI) with an incidence rate of less than 0.1% of all intracranial tumours. Most lipomas are asymptomatic pericallosal lesions sometimes presenting with seizures or headache. Corpus callosum agenesis and defects of midline structures differentiation may be present. Callosal lipomas are of two types: Anterior bulky tubulonodular variety associated with forebrain and rostral callosal anomalies, and posterior ribbon-like curvilinear lipoma generally seen with a normal or near normal corpus callosum. Corpus callosal hypogenesis/agenesis is seen in up to 90% of anterior and 30% of posterior pericallosal lipomas. The association of corpus callosal lipoma with choroid plexus lipoma is variable with its reported incidence rate being 20-50%. A 50-year-old patient was referred to our department for CT scan of brain with history of recent onset of headache and one episode of seizure. We present the imaging findings in this rare case of callosal tubulonodular lipoma having prominent intralesional vessels and extensive calcification with a concomitant intraventricular lipoma in a patient with dysgenetic corpus callosum.

Sami Ayed Alshammary, Balaji Duraisamy, Abdullah Alsuhail, Mohammad Mhafzah, Lobna M. A. Saleem, Nadir Mohamed, Savithiri Ratnapalan
April-June 2016, 4(2):116-121
Background: The terminally ill diabetic inpatients who had blood glucose monitoring continued until the day of death ranged from 32% to 76% according to previous studies. Researches regarding the management of diabetes in palliative care services in Saudi Arabia are insufficient, although it is of high prevalence. Balancing the goals of avoiding symptoms of hyperglycaemia and hypoglycaemia as well as minimising the burden of blood glucose monitoring and treatment have become a struggle to palliative care physicians due to limited evidence-based resources. This intensifies the complexity of managing diabetes during a terminal illness. Objective: The purpose of this study was to describe the management of diabetes among patients who were admitted to hospital-based palliative care unit (PCU) at King Fahad Medical City, Riyadh, Saudi Arabia. Methods: A retrospective chart review, cohort study for all PCU inpatients was done. The study was conducted on the charts of 12 months from January to December 2013. Measures included diabetes prevalence, monitoring of blood glucose by laboratory and/or bedside testing and diabetes treatment with the use of oral hypoglycaemic agents and insulin. Prevalence of diabetes associated comorbidities, hypertension and dyslipedemia were also measured along with their treatment. A descriptive analysis of collected data was carried out. Results: Eighteen adult diabetic patients (15.25%) out of the whole 118 patients admitted to PCU over the 12 months' study period were reported. Ten (55.6%) were males, and 8 (44.4%) were females, with a mean age of 59.26 years. Blood glucose monitoring in the diabetic patients was done for ten patients; bedside glucometer utilized for 9 patients (50%), glucometer + serum glucose measurement done in one patient (5.6%), and no glucose monitoring was done in eight patients (44.4%). The majority of the patients 11/18 (61%) stayed at the hospital until death while 7/18 (39%) did well and were discharged. The monitoring of blood sugar was continued for six patients until the last week of life. Blood glucose management dropped to 33% at the end of life. Initially, half of the patients (50%) had their blood glucose managed with hypoglycaemic medications with or without insulin. This dropped during the last week of life to 33%. In the comorbidity group, 72% were using antihypertensive or lipid lowering agents, as a result of which it dropped to 50% during the last week of life. Conclusion: Diabetes management varied among PCU patients. There is a real need for evidence-based guidelines for diabetes management among patients at the end of life. These guidelines should be tailored to patients' individual preferences in goals of care. Advance care planning should include discussion about patient preferences for management of diabetes at the end of life.

Aetiology of acute gastroenteritis in children in Najran region, Saudi Arabia
Mohamed Saeed Zayed AlAyed, Ahmed Morad Asaad, Abdulrab Ahmed Mahdi, Mohamed Ansar Qureshi
May-August 2013, 1(2):84-89
Objectives: Gastroenteritis is a leading cause of childhood morbidity and mortality in developing countries. Our aim was to determine the prevalence of bacterial, viral and parasitic aetiology of gastroenteritis in children aged < 5 years in the Najran region, south-western Saudi Arabia, to determine the contribution of these enteropathogens in childhood diarrhoeal diseases and to put forward effective preventive measures for controlling the disease in the future. Design and Setting: A descriptive study conducted at Najran Maternity and Children's Hospital and the Microbiology Department of the Najran University College of Applied Medical Sciences from October 2011 to June 2012. Patients and Methods: Stool samples were collected from 326 children aged ≤ 5 years with diarrhoea and examined for bacterial, viral and parasitic enteropathogens. Results: Seventy-two (22.1%) samples were positive for viral pathogens, including 56 (17.2%), 12 (3.7%) and 4 (1.2%) samples for rotavirus, adenovirus and astrovirus, respectively. Thirty-five (10.7%) samples were positive for bacterial pathogens, including 28 (8.6%) and 7 (2.1%) samples for Salmonella and Shigella spp. isolates, respectively. Pathogenic parasites were detected in only 4 (1.2%) samples, including 3 (0.9%) Giardia lamblia and 1 (0.3%) Entamoeba histolytica isolates. Conclusions: Rotavirus is the most common pathogen in paediatric acute gastroenteritis in the Najran region. This fact, in combination with the severity of the infections, warrants consideration of a rotavirus vaccine in the childhood immunization program in Saudi Arabia. On the basis of clinical and laboratory parameters, it appears possible to distinguish between the different causative agents of acute gastroenteritis.

Global non-communicable disease prevention: Building on success by addressing an emerging health need in developing countries
Ali H Mokdad
April-June 2016, 4(2):92-104
Non-communicable diseases (NCDs) are beginning to dominate the global health landscape. Despite numerous calls to action for chronic disease preventive and control, the response to the urgency is insufficient, especially in terms of their prevention efforts. Worldwide, the total number of people dying from NCDs is twice that of the combined total of all infectious diseases (including HIV/AIDS, tuberculosis and malaria), maternal and perinatal conditions and nutritional deficiencies. Cardiovascular disease is the leading cause of death in the world and accounts for about 30% of all deaths. Increased interventions in global NCDs prevention and control programs are needed as a global strategy to improve the current scenario. Specifically, we present this case for the United States to provide leadership in global NCD prevention and control.

Fast-track surgery: A new concept of perioperative management of surgical patients
Gabriel Rodrigues, Chandini Ravi, Raghunath Prabhu
September-December 2013, 1(3):114-121
In the past few decades, surgery has advanced greatly because of an improved understanding of perioperative pathophysiology, development of minimally invasive operative techniques and advanced anaesthetic techniques. Fewer operations are requiring extended periods of hospital stay and a growing number of procedures are performed on an ambulatory basis. The pressure on medical systems is continuously growing as a result of economic constraints, increasing numbers of patients undergoing surgical procedures and greater patient autonomy. Patient awareness is steadily increasing along with their participation in their own care, leading to expectations of a higher standard of care. This has led to the development of a new concept of fast-track surgery.
