1.  Topical Application of Sadat-Habdan Mesenchymal Stimulating Peptide (SHMSP) Accelerates Wound Healing in Diabetic Rabbits 
Experimental Diabetes Research  2012;2012:531961.
Objective. Diminished wound healing is a common problem in diabetic patients due to diminished angiogenesis. SHMSP was found to promote angiogenesis. The present study was carried out to examine the effect of this peptide in healing of wounds in diabetic rabbits. Materials and Methods. Twenty male New Zealand rabbits were used in this study. Diabetes mellitus was induced and the rabbits were randomly divided into two equal groups: control group and peptide group. A-full thickness punch biopsy was made to create a wound of about 10 mm on the right ears of all rabbits. Every day, the wound was cleaned with saline in control groups. In the peptide group, 15 mg of SHMSP was applied after cleaning. On day 15th, all animals were sacrificed, and the wounds were excised with a rim of 5 mm of normal surrounding tissue. Histo-pathological assessment of wound healing, inflammatory cell infiltration, blood vessel proliferation, and collagen deposition was performed. Results. There were no deaths among the groups. There was significant increase in wound healing, blood vessel proliferation and collagen deposition, and significant decrease in inflammatory cell infiltration in the peptide group compared to the control group. Conclusion. Topical application of SHMSP improves wound healing in diabetic rabbits.

2.  The status of Vitamin D in medical students in the preclerkship years of a Saudi medical school 
Background:
The prevalence of vitamin D deficiency has recently been recognized in different parts of the world, even affecting healthy populations. The deficiency of vitamin D can lead to rickets in children and osteomalacia in adults. Few studies have been done to evaluate the status of vitamin D in the medical community. The objective of this study was to evaluate the prevalence of low levels of vitamin D in healthy Saudi medical students.
Materials and Methods:
A cross-sectional study was carried out in November 2009 on male and female students in the preclerkship years of medical school at the King Faisal University, Dammam. Data on age, consumption of dairy products and seafood, and exposure to sunlight were collected. The body mass index was calculated. Approximately, 15 ml of blood was extracted for the measurement of serum calcium, serum albumin, serum phosphorus, alkaline phosphatase, fasting parathyroid hormone, and vitamin D levels. Vitamin D deficiency was defined as serum 25-hydroxy vitamin D < 50 nmol/l. Comparison between groups was done for statistical significance using an unpaired t-test. Significance was set at P < 0.05 using 95% CI for all comparisons.
Results:
The data from 95 male and 103 female students were analyzed. The mean age for all students was 19.54 years. In 100% of the students, the vitamin D level was low. The prevalence of vitamin D deficiency in all students was 96.0% (92.64% in males and 99.03% in females), while the remaining 4% had vitamin D insufficiency. The mean 25-hydroxy vitamin D level was 26.83 ± 12.60 nmol/l in males and 16.03 ± 8.28 nmol/l in females (P-value = 0.0001). Males had a statistically significant higher body mass index as well as consumption of dairy products, while the consumption of seafood was significantly higher in females. There was no difference between the two groups in terms of exposure to the sun.
Conclusion:
Vitamin D deficiency was highly prevalent among medical students included in this study. An urgent action has to be taken in order to prevent adverse consequences of low vitamin D in the young, otherwise healthy populations.

3.  Simulation-based medical teaching and learning 
One of the most important steps in curriculum development is the introduction of simulation- based medical teaching and learning. Simulation is a generic term that refers to an artificial representation of a real world process to achieve educational goals through experiential learning. Simulation based medical education is defined as any educational activity that utilizes simulation aides to replicate clinical scenarios. Although medical simulation is relatively new, simulation has been used for a long time in other high risk professions such as aviation. Medical simulation allows the acquisition of clinical skills through deliberate practice rather than an apprentice style of learning. Simulation tools serve as an alternative to real patients. A trainee can make mistakes and learn from them without the fear of harming the patient. There are different types and classification of simulators and their cost vary according to the degree of their resemblance to the reality, or ‘fidelity’. Simulation- based learning is expensive. However, it is cost-effective if utilized properly. Medical simulation has been found to enhance clinical competence at the undergraduate and postgraduate levels. It has also been found to have many advantages that can improve patient safety and reduce health care costs through the improvement of the medical provider's competencies. The objective of this narrative review article is to highlight the importance of simulation as a new teaching method in undergraduate and postgraduate education.

4.  MEDICINE AND CLINICAL SKILLS LABORATORIES 
The main objective of the medical curriculum is to provide medical students with knowledge, skills and attitudes required for their practice. A decade ago, the UK Medical Council issued a report called “Tomorrow's Doctors”1 which called for the reduction in the factual content of the medical course with the promotion of problem-based and self-dedicated learning. This report was the basis for a move toward an extensive reform of the medical and nursing curricula. The new reformed curricula enhanced the integrated medical teaching and emphasized the teaching and learning of clinical skills. However, there were still concerns about the standards and appropriateness of the skills of new medical graduates.2
The changes in the teaching and learning methods, the radical changes in the health care delivery and the rapid growth of technology challenged the traditional way of clinical skills development and led to the emergence of clinical skills laboratories (CSLs) in the medical education of many medical and nursing schools. With the proliferation of the CSLs, it is important to evaluate and introduce the reader to their applications, bearing in mind the paucity of information on this subject particularly over the last couple of years. This article is based on literature review.

5.  LEPTIN LEVELS IN NORMAL WEIGHT AND OBESE SAUDI ADULTS 
Objective:
The purpose of the study was to measure serum leptin in normal weight and obese individuals, and assess its relation to anthropometric measures and metabolic indices.
Methods:
The study was conducted at King Fahd Hospital of the University, Saudi Arabia, from January 2003 to June 2004. Subjects included in the study were all non-diabetic normotensive adults. Variables measured were body mass index (BMI), waist to hip ratio (WHR), blood pressure, serum leptin, insulin, glucose, and lipids.
Results:
Included were 43 non-obese subjects (20 men and 23 women) with the mean age of 25.8 + SD 5.3 y for men and 23.9 + SD 1.9 y for women and their mean BMI was 23.1 ± 1.4 for men and 23.0 ± 1.8 for women. Serum leptin was significantly higher in women 8.8 + SEM 2.10 than men 2.2 + SEM 0.26 ng /ml.Also included were 46 obese subjects (25 men and 21 women) with a mean age of 29.4 + SD 7.6 y for men and 28.8 + SD 6.2 y for women and a mean BMI of 35.5 ± 5.7 for men and 35.6 ± 4.4 for women. Serum leptin was significantly higher in women 23.0 + SEM 3.98, than men 12.5 + SEM 2.24 ng /ml. Serum leptin was significantly higher in obese men and women compared to non-obese subjects. Serum leptin significantly, and positively correlated with BMI (r 0.440), hip circumference (r 0.425), serum insulin (r 0.334), and HOMA IR (r 0.334).There was no correlation with mean age, mean systolic BP, mean diastolic BP, or WHR.
Conclusions:
Serum leptin increased with obesity, and was higher in women than men, both lean and obese. Serum leptin correlated positively with BMI and hip circumference. Though, correlation between leptin and insulin resistance was found, they probably reflect two different metabolic compartments.

6.  Favorable impact of Nigella sativa seeds on lipid profile in type 2 diabetic patients 
Background and Aim:
The atherogenic pattern of dyslipidemia associated with type 2 diabetes mellitus (DM) has been increasingly discussed. We have recently reported a hypoglycemic effect of Nigella sativa (NS) seeds in patients with type 2 DM. In this study we sought to assess the impact of NS seeds on lipid profile in type 2 diabetic patients.
Patients and Method:
A total of 94 patients with type 2 DM were recruited and divided into 3 dose groups. Capsules containing NS were administered orally in a dose of 1, 2, and 3 g/day for 12 weeks. All patients were subjected to measurement of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) before treatment and 4, 8, and 12 weeks thereafter.
Results:
Patients receiving 1 g/day NS seeds for 12 weeks (group 1) showed nonsignificant changes in all the parameters except for a significant increase in HDL-c after 4 weeks of treatment. However, patients ingested 2 g/day NS displayed a significant decline in TC, TG, and LDL-c, and a significant elevation in HDL-c/LDL-c, compared with their baseline data and to group 1 patients. Increasing NS dose to 3 g/day failed to show any increase in the hypolipdemic effect produced by the 2 g/day dose.
Conclusion:
NS supplementation at a dose of 2 g/day for 12 weeks may improve the dyslipidemia associated with type 2 diabetic patients. Therefore, NS is a potential protective natural agent against atherosclerosis and cardiovascular complications in these patients.

7.  Frequency of Low Bone Mineral Density in Saudi Patients with Inflammatory Bowel Disease 
Background/Aims:
Metabolic bone disease is common in patients with inflammatory bowel disease (IBD). Our aim was to determine the frequency of bone loss among Saudi patients with IBD and possible contributing risk factors.
Settings and Design:
We retrospectively reviewed Saudi patients with IBD, between 18 and 70 years of age, who had bone mass density (BMD) determined by dual-energy X-ray absorptiometry scanning at one of three hospitals in the Kingdom of Saudi Arabia from 2001 to 2008.
Patients and Methods:
Case notes and BMDs results were carefully reviewed for demographic and clinical data. Low bone mass, osteopenia, and osteoporosis were defined according to the WHO guidelines.
Statistical Analysis Used:
Predictive factors for BMD were analyzed using group comparisons and stepwise regression analyses.
Results:
Ninety-five patients were included; 46% had Crohn's disease (CD) and 54% had ulcerative colitis (UC). The average age was 30.9±11.6 years. Using T-scores, the frequency of osteopenia was 44.2%, and the frequency of osteoporosis was 30.5% at both lumbar spine and proximal femur. Only 25.3% of patients exhibited a BMD within the normal range. Our results revealed a positive correlation between the Z-score in both the lumbar spine and the proximal femur and body mass index (BMI) (P=0.042 and P=0.018, respectively). On regression analysis BMI, age, and calcium supplementation were found to be the most important independent predictors of BMD.
Conclusions:
Saudi patients with IBD are at an increased risk of low BMD and the frequency of decreased BMD in Saudi patients with CD and UC were similar. BMI and age were the most important independent predictors of low BMD.

8.  Influence of vitamin D levels on bone mineral density and osteoporosis 
Annals of Saudi Medicine  2011;31(6):602-608.
BACKGROUND AND OBJECTIVES:
The effects of vitamin D on bone mass remain to be understood. This study was conducted with the objective of evaluating the influence of 25-hydroxyvitamin D (25OHD) levels on bone mineral density (BMD) among Saudi nationals.
DESIGN AND SETTING:
Cross-sectional study carried out at university hospital from 1 February 2008 to 31 May 2008.
SUBJECTS AND METHODS:
Healthy Saudi men and women in the peak bone mass (PBM) age group and those aged ≥50 years were recruited from the outpatient department of King Fahd University Hospital, Al Khobar, Saudi Arabia, between February 1, 2008, and May 31, 2008. Patient age and sex were documented, and body mass index was calculated. Hematological, biochemical, and serum 25OHD tests were performed. BMD was determined by dual-energy x-ray absorptiometry of the upper femur and lumbar spine. Patients were divided into three groups, based on their 25OHD level.
RESULTS:
Data from 400 patients were analyzed. Among individuals with a normal 25OHD level, 50% of women and 7% of men in the PBM age group and 26.4% of women and 49.2% of men aged ≥50 years had low bone mass. In patients with 25OHD insufficiency, 84.2% of women and 88.9% of men in the PBM age group and 83.3% of women and 80% of men aged ≥50 years had low bone mass. Results for patients with 25OHD deficiency revealed that none of the men and women in the PBM age group or ≥50 years old had normal BMD. Significant positive correlations between 25OHD level and BMD and significant negative correlations with parathyroid hormone were shown in most of the groups.
CONCLUSIONS:
This study showed that the vitamin D level significantly influences BMD reading among Saudi individuals. Evaluation and treatment of hypovitaminosis D should be considered during management of low bone mass.

9.  Are We Missing Osteoporosis-Related Vertebral Fractures in Men? 
Asian Spine Journal  2011;5(2):107-110.
Study Design
Retrospective study.
Purpose
To assess the prevalence of osteoporosis related spinal fractures among Saudi Arabian males.
Overview of Literature
Vertebral fractures are the most common complication of osteoporosis and is the first sign in both sexes and only 25 to 30% of radiographically observed vertebral deformities are recognized.
Methods
We analyzed the chest radiographs of consecutive Saudi Arabian men ≥ 50 years and who visited the emergency room of King Fahd University Hospital, Al Khobar, Saudi Arabia for a period of 12 months between November 1, 2007 and October 31, 2008. The site and type of fractures were classified as per the semi-quantitative technique. The other data retrieved from the medical records of patients included medications and clinical investigations for osteoporosis.
Results
Nine hundred seventy chest radiographs were performed during the study period and 876 radiographs could be analyzed. One hundred fifteen patients (13.1%) had 157 fractures. The mean age was 67.85 ± 10.1 years. There was more than one fracture in 21 patients (18.2%). The majority of fractures (n = 102, 64.9%) were observed in thoracic spine. Seventy-one (45.2%) fractures were classified as mild, 54 (34.4%) were moderate and 32 (20.4%) were severe. For 26 (22.6%) patients, the report of the radiologist highlighted the fracture.
Conclusions
Saudi Arabian males with osteoporosis continue to be missed despite the high prevalence osteoporosis leading to vertebral fractures. We believe it is important for physicians to identify vertebral fractures early and treat then appropriately before an extremity fracture occurs with high mortality.
