In this briefing, some specific problems facing the petroleum industry in Saudi Arabia over the next few years are considered. They include: marketing difficulties caused by a glut in the Asian market to which Saudi Arabia is increasingly directing sales; the current high cost of maintaining a surplus production capacity that is unlikely to be used in the short term; a need to revise the budget to take into account the unexpected collapse in oil revenues in recent months; a need to prevent gross overproduction by both OPEC and non-OPEC rivals in order to prevent either loss of market share or persistent low prices.

In 1985, Saudi Arabia's population stood at 9.6 million, with an annual growth rate of 2.8%. The infant mortality rate was 78/1000 and life expectancy was 60 years. Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development. PMID:12178138
This presentation reviewed the geopolitics of energy in the Middle East, with particular reference to Saudi Arabia as a potential hotspot. The author examined the question of who actually governs Saudi Arabia and the core relationship between Crown Prince Abdullah and the interior Minister, Prince Nayef. Issues regarding the country's social stability were discussed with reference to the high unemployment rate. The financial security of Saudi Arabia was also discussed with reference to the need for economic and political reform. Expectations for Saudi petroleum output were outlined along with regional spurs for energy competition and OPEC participation
Objective was to determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol >=5.2 mmol/l) and hypertriglyceridemia (HT) (total triglycerides >=1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipidemia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating problem habits and increasing physical activity are of considerable importance to our community. (author)
This article reviewed the literature on the epidemiology, consumption, trade, control, prevention, and treatment of tobacco smoking in Saudi Arabia. The prevalence of current smoking in Saudi Arabia ranges from 2.4-52.3% (median = 17.5%. Among school students, the prevalence of current smoking ranges from 12-29.8% (median = 16.5%, among university students from 2.4-37% (median = 13.5%, and among adults from 11.6-52.3% (median = 22.6%. In elderly people, the prevalence of current smoking is 25%. The prevalence of smoking in males ranges from 13-38% (median = 26.5%, while in females it ranges from 1-16% (median = 9%. To conclude, smoking is prevalent in the Saudi population at different age groups. The prevalence of current smoking is much higher in males than in females at different ages. More research is needed in the area of prevention and treatment of smoking.

Energy and the Saudi economy were discussed with reference to reserves, oil prices, gross domestic product co-movements, and gas resources and development. In particular, this presentation reviewed the emergence and prospects of the petrochemical industry of Saudi Arabia using statistical, institutional and economic analyses relying on a wide range of data sources. Saudi Arabia has the world's largest oil reserves, at 263 billion barrels. In the 1990s, more than 54 Tcf of non-associated gas reserves were added to Saudi Arabia's resource base, more than doubling its proven non-associated gas reserves to approximately 97 Tcf. With 138 Tcf of associated gas reserves, Saudi Arabia holds the fourth largest gas reserves in the world at nearly 235 Tcf. First, this presentation identified and evaluated the endowments as well as the institutional and strategic forces that are driving the growth of the petrochemical industry in Saudi Arabia. Some of the economic, technical and geopolitical factors that influenced the increase in oil prices between 2003 and 2005 were also identified. The dual relationship between the Saudi petrochemical industry and long term economic performance of the Saudi economy were illustrated within a broad domestic economic diversification policy objective. The future growth prospects and challenges facing the Saudi petrochemical industry were also evaluated with respect to the evolving economic reform policies and Saudi international commitments. Potenand Saudi international commitments. Potential implications for the petrochemical industry in North America were also identified, in terms of technology transfer and having Saudi Arabia secure the markets in order to meet its commitment to the World Trade Organization. tabs., figs

To describe the epidemiology and clinical features of stroke in a prospective and retrospective cohort of Saudi children and ascertain the causes, pathogenesis, and risk factors. The Retrospective Study Group (RSG) included children with stroke who were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the period July 1992 to February 2001. The Prospective Study Group (PSG) included those seen between February 2001 and March 2003. During the combined study periods of 10 years and 7 months, 117 children (61 males and 56 females, aged one month-12 years) were evaluated; the majority (89%) of these were Saudis. The calculated annual hospital frequency rate of stroke was 27.1/100,000 of the pediatric (1month-12 years) population The mean age at onset of the initial stroke in the 104 Saudi children was 27.1 months (SD=39.3 months) median and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). Large-vessel infarcts (LVI, 51.9%) were more common than small-vessel lacunar lesions (SVLL, 19.2%). Five patients (4.8%) had combined LVI and SVLL. Intracranial hemorrhage was less common (18.2%), whereas sinovenous thrombosis was diagnosed in 6 (5.8%) patients. A major risk factor was identified in 94 of 104 (89.4%) Saudi children. Significantly more hematologic disorders and coagulopathies were identified in the PSG compared thies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and cardiac diseases in 6 (5.8%). Six patients (5.8%) had moyamoya syndrome, which was associated with another disease in all of them. Inherited metabolic disorders (3.8%) included 3 children with Leigh syndrome and a 29-months-old girl with mitochondrial encephalomypathy, lactic acidosis, and stroke-like episodes. Systemic vascular disease was a risk factor in 3 children (2.9%) including 2 who had hypernatrmic dehydration; and post-traumatic arterial dissection was causative in 3 cases (2.9%). Several patients had multiple risk factors, whereas no risk factor could be identified in 11 (10.6%). Due to high prevalence and importance of multiple risk factors, a comprehensive investigation, including hematologic, neuroimaging and metabolic studies should be considered in every child with stroke.

A total of 637 passive radon dosemeters (CR-39 nuclear track detectors in a closed chamber) were used in a survey in 400 houses in Saudi Arabia. The radon concentration was found to vary from 5 to 36 Bq.m-3 (0.13 to 0.98 pCi.l-1) with a mean of 16 Bq.m-3 (0.43 pCi.l-1). The unoccupied houses showed a concentration of 29+-7 Bq.m-3 (0.78+-0.19 pCi.l-1) double that of the occupied houses, 14+-1 Bq.m-3 (0.39+-0.02 pCi.l-1), in the same area. The radon daughter concentration measured with a Working Level monitor in 17 unoccupied houses was found to vary from 1.35x10-3 to 24x10-3 WL with an average of 6.9+-1.4x10-3 WL. The average exhalation rate measured in 37 houses by 95 passive detectors in cans sealed to the walls ranged from 0.013 to 0.044 Bq.m-2.h-1(0.35 to 1.2 pCi.m-2.h-1) with an average of 0.021+-0.003 Bq.m-2.h-1(0.56+-0.09 pCi.m-2.h-1). This survey is the first in Saudi Arabia (a hot climate) and can usefully be compared with similar surveys in countries with cold climates. (author)

Full Text Available People should be aware of sources of health hazards, such as radon gas; and efforts should be made to educate them. Radon awareness among people is important for monitoring its level in their residential houses to reduce the risk of ad-verse health effects. Furthermore, radon awareness among public would support and facilitate researchers working for such surveys during the field work. In the present study, a public survey was conducted to investigate radon awareness level among Saudi people in Riyadh. A questionnaire was designed and distributed among 2297 persons of various educational background. It was found that about 82% of the Saudi public in Riyadh were ignorant of radon and its associated health risks. It was also found that only ~18% of educated public knew about radon. It was concluded that Saudi public needs to be educated in this respect properly.

The social, political, and economic implications of the immigrant presence in Saudi Arabia are explored. The author notes that about one-third of the population of the country is made up of working nonnationals. The tensions that exist are examined, with reference to the exclusion of the migrants from Saudi Arabian society and the extreme imbalance in the sex ratio caused by predominately male migration. The author suggests that dependence on migrant labor is likely to increase rather than decrease as Saudi nationals are oriented toward nontechnical studies and Saudi women are excluded from the labor force.

Full Text Available Background: Human rotavirus, an important causative agent of severe gastroenteritis in infants and young children worldwide, leads to high morbidity in both developing and developed countries, including Saudi Arabia, and high mortality in developing countries. Effective control depends upon an accurate understanding of disease burden and the relative importance of circulating serotypes. Methods: We examined the epidemiology and disease burden of rotavirus in Saudi Arabia through a review of 22 published studies of rotavirus and the aetiology of diarrhoea carried out from 1982 to 2003. Results: The prevalence of rotavirus infection ranged between 10% to 46% with a median of 30%. Most cases were among children less than 2 years of age, and particularly in the first year of life. There were significant differences in seasonality within Saudi Arabia, with increased infection during winter in some cities and during summer in others. G1 was the predominant serotype followed by G4, G3 and G2, in 4 studies where strains had been G-typed. The prevalence of nontypeable strains ranged from 11.0% to 31.3%. No data were available on P types. Results of electropherotyping in 4 studies revealed that the long electropherotype was predominant. Conclusion: Rotavirus is an important cause of severe diarrhoea in Saudi children. However, the available data on rotavirus strains in circulation are limited and there is an urgent need for up-to-date and comprehensive studies to evaluate rotavirus strains in circulation and identify unusual types that could be incorporated into future vaccines.

Full Text Available Background: The epidemiology of acute pancreatitis in Saudi Arabia is greatly different from that in Western Countries. Aim: To evaluate and compare the risk factors and clinical features of acute pancreatitis. Patients and Methods: The course of acute pancreatitis was retrospectively analyzed in 218 patients who had their first attack and were admitted at Riyadh Armed Forces Hospital during the period 1.01.85-31.05.97. Results: From these 218, 130 patients were in the age group of 20-55 yrs. (74+, 56>, 76 were > 55 yrs. Of age (42 +, 34> and only 12 were < 20 yrs. (6 Females, 6 Males. The precipitating cause was biliary disease in 147, post-operative in ten, hyperlipidemia in seven, post-ERCP in five, infection in four and alcohol in four. Four had rare causes and 37 no obvious cause. Severe pancreatitis diagnosed in 70 patients, 51 of them were > 55 yrs. of age and 45 were precipitated by biliary disease. Twenty six developed complications (21 were > 55 yrs. old and four deaths. Twenty two patients of these who had severe form had diabetes mellitus, 37 had fever at presentation and 56 had leukocytosis. Conclusions: The commonest etiology of acute pancreatitis was biliary in 147 patients (67.5% followed by postoperative pancreatitis in 10 patients (4.6%. Alcohol as etiological factor was rare (1.8%. The epidemiology and the risk factors differed markedly in Saudi Arabia, where alcohol is prohibited

Full Text Available This study explores the attitudes of Saudi EFL teachers toward explicit instruction of readingstrategies. The study also compares actual practices of Saudi teachers with their beliefs and attitudes towardreading strategy instruction. In this study, quantitative data were collected using an attitude questionnaire,while qualitative data were collected using observation and semi-structured interviews. The quantitative dataobtained were analyzed by using means, standard deviations, and the Pearson product-moment correlationcoefficient. Qualitative data from a semi-structured interview were also analyzed to explore teachers'knowledge about reading strategy instruction. The results of this study show that Saudi teachers believestrongly in the importance of cognitive reading strategies and that they have insufficient knowledge of theimportance of metacognitive reading strategies. The study ends with recommendations for training Saudi EFLteachers in some of the most effective metacognitive reading strategies to help students plan, monitor, evaluate,and regulate their learning.

Objective was to determine the prevalence of osteoporosis in healthy Saudi men. We randomly recruited 429 Saudi men from the community. The recruited Saudi men were subjected to an interview to reveal their lifestyle parameters, calcium intake and level of activity. Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)

Demographic movements likely to be taking place in Saudi Arabia were hypothesized on the basis of general knowledge. The discussion reports on population size, general Arab demographic patterns, general determinants of fertility, Arab fertility patterns, Saudi fertility patterns, mortality in general, mortality in the Middle East, mortality in Saudi Arabia, Saudi Arabian population growth, immigration, the changing composition of the work force, and third plan targets. Some doubt exists as to the size of Saudi Arabia's population, but there is little question that the total is growing rapidly. This expansion is taking place through stepped up immigration and a relatively high natural growth of indigenous Saudis, but statistics on population size, structure, and on the number of births and deaths leaves the magnitude of a number of important demographic trends in doubt. Yet, considerable evidence exists that several of the Arab countries in the region with fairly good demographic data are likely to have similar demographic patterns. In depth analysis of the demographic dynamics of these countries, particularly Jordan and Kuwait, identified several common elements bearing on several key parameters. Using what Saudi data is available and making comparisons with these neighboring countries, one can, based on expected levels of birth and death rates, indirectly infer the natural growth of Saudi Arabia's population. With several notable exceptions, Saudi Arabia's demographic patterns show a marked similarity to those experienced in the region as a whole. The average rate of population growth in both Saudi Arabia and the Arab region is about 3% a year and in both instances fertility rates are high. The demographic structure of these countries is characterized by the youthfulness of the population. In most of the Arab countries, the population aged 15 years or under accounts for over 48% of the population. The rate of the economically active population is low, ranging from 22% to 32% of the total population, with the female participation rate varying from 3.5% to 18.5%. In the nonagricultural sector, the average activity rate of women over the age of 15 usually does not exceed 6%. Arab countries are also characterized by their high infant mortality rates. In 1975 these rates ranged from 60 to 200/1000. Illiteracy rates for the group, as a whole, are also high, and they are significantly higher among women than among men. A multipurpose survey conducted in Saudi Arabia during 1976 and 1977 reported a live birthrate of 54.2/1000. This is somewhat above the UN figure of 49.5 for the country and over the average for Arab countries of 46.6 for 1975. The mortality rate for the Saudi population is 14.1/1000. If one accepts the birth and death rates indicated by the multipurpose survey, the population is growing at a national rate of 3% or more per year. PMID:12340437

The article reviews the literature on the problem of nutritional disorders in Saudi Arabia. Most of the studies reveal problems of anaemia and a mild to moderate degree of stunting and wasting among preschool children. The causes are, apparently, ignorance and misconception rather than purely economic. Recently, overnutrition has been observed as a problem among the middle and upper class of urban societies. In general, an improvement in the nutritional status of the Saudis has been observed over the last two decades. This is a repercussion of socioeconomic development and improvement in education, dietary habits, and environmental conditions. The time is ripe to create Saudi standards for health and nutrition. These will be used as yardsticks for planning and evaluation of health and nutritional programmes. PMID:3294076

Full Text Available Background: Smoking has been found to be associated with carotid atherosclerotic disease. Since smoking is an important public health problem, because it may be an essential risk factor for carotid artery plaques. Therefore the researchers tried to explore the powerful of this association, the researchers investigated smokers as unique suspected risk factor for carotid plaques beside the age. Methods: In observational cross-sectional study, 31 smokers with mean age of 56, were studied by B- mode ultrasound. Carotid arteries for all participants were examined by using 7MHrz linear transducer. Both saggital and transverse views were applied to evaluate the right and left common carotid arteries. Results: The frequency of carotid plaque was 35.5%. 54.5 % of these occurred in population group that smoke > 20 cigarettes per day. All plaques were presented in population of age above 53 years old. There was association between smoking frequency and age with the increases of plaque size. Conclusion and recommendations: The study suggested that there is a significant association between carotid plaques and smoking in Saudi smokers. In addition it showed that carotid plaque may present at age of 54 years old in smokers. The researchers recommended that further studies were needed. Moreover intensive health promotion against smoking in the KSA. represents an essential issue.

The haemoglobin (Hb) patterns of 345 Shiite Saudi Arab cord bloods were examined by alkaline starch-gel electrophoresis. A fast-moving component, identified by structural analysis as Hb Bart's, was found in 52% of cases, the highest incidence of this variant yet recorded. The levels of Hb Bart's ranged from 0.5 to 16% of the total haemoglobin. The relative rates of synthesis of the alpha, beta and gamma-chains, measured by [3H]leucine incorporation, were estimated in 12 newborn Arab infants. There was an excellent correlation between the amount of Hb Bart's and the alpha/non-alpha-globin-chain production ratio. Furthermore there was a significant correlation between the level of Hb Bart's and morphological abnormalities of the red cells and the mean cell haemoglobin (MCH). These findings indicate that elevated levels of Hb Bart's in this population are due to the presence of alpha thalassaemia. The absence of hydrops fetalis and the rarity of Hb-H disease despite the intense inbreeding in this population, points to an alpha-thalassaemia genotype that is, in terms of phenotypic expression, intermediate between the heterozygous state for alpha-thalassaemia I and Hb-H disease. A possible molecular basis for this genotype is suggested. PMID:1238097

Nuclear magnetic resonance (NMR) spectroscopy with proton (/sup 1/H) and carbon 13 (/sup 13/C) has been used to determine the structural characteristics of asphaltenes from four commercial Saudi Arabian crude oils. These characteristics are important to refiners that have deep conversion processes to determine yields from the residual fractions of the Saudi crudes, and to determine the operating parameters of the process units. The spectra obtained give some structural similarities among the crude oils, as well as some differences. Values of various structural parameters have been tabulated from the spectra

Classic homocystinuria is an autosomal recessive disorder due to cystathionine beta-synthase deficiency. The clinical, radiological and neurophysiological findings of classic homcystinuria diagnosed at King Faisal Specialist Hospital and Research Centre (KFSH and RC) are presented in this report. Twenty-four patients (15 females and 9 males) were referred to KFSH and RC for work-up of mental retardation, seizures, thrombo-embolic episodes and dislocation of the ocular lenses. The common clinical findings included ectopia lentis (20 patients), skeletal system involvement (18 patients), vascular system involvement (9patients), and mental retardation (all patients to varying degrees). Unusual findings consisted of a patient who developed severe lower gastrointestinal bleeding, a patient with insulin-dependent diabetes mellitus, probably due to vasculopathy, and other having severe bronchiectasis, which may have been due to fibrillin disruption, and required the resection of a lobe of lung. The parents of 21 patients were first-degree relatives, and 19 patients had one or more family members affected by the same disease. All patients had markedly elevated plasma levels of methionine. Cystathionine synthase activity in the fibroblast was measured in 25% of the patients and was deficient. Only four patients responded to pyridoxine and their methionine level decreased to almost normal range. The aim of this study was to increase the awareness of this disease in the scientifiawareness of this disease in the scientific and medical community, in particular in the general pediatrician working in Saudi Arabia who first encounters the clinical manifestations of disease. Early detection through tandem mass spectrometry of blood spot screening and treatment are important and may prevent the major complications of this disease. (author)

To assess the prevalence and characteristics of medication errors (ME) in patients admitted to King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia. Medication errors are documented by the nurses and physicians standard reporting forms (Hospital Based Incident Report). The study was carried out in King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia and all the incident reports were collected during the period from January 2008 to December 2009. The incident reports were analyzed for age, gender, nationality, nursing unit, and time where ME was reported. The data were analyzed and the statistical significance differences between groups were determined by Student's t-test, and p-values of <0.05 using confidence interval of 95% were considered significant. There were 38 ME reported for the study period. The youngest patient was 5 days and the oldest 70 years. There were 31 Saudis, and 7 non-Saudi patients involved. The most common error was missed medication, which was seen in 15 (39.5%) patients. Over 15 (39.5%) of errors occurred in 2 units (pediatric medicine, and obstetrics and gynecology). Nineteen (50%) of the errors occurred during the 3-11 pm shift. Our study shows that the prevalence of ME in our institution is low, in comparison with the world literature. This could be due to under reporting of the errors, and we believe that ME reporting should be made less punitive so that ME can be studied and preventive measures implemented (Author)d preventive measures implemented (Author).

Most of the Saudi desalination plants are of the multistage flash (MSF) type. These plants are often constructed as a dual purpose installation, producing power and water. MSF plants are considered to be energy intensive, where the energy cost is a major controlling parameter in the overall cost of desalination. Oil price fluctuations affect the cost of desalted water significantly. On the other hand, nuclear power offers price stability in the long term. Nuclear powered desalination provides long term availability of indigenous fuel, as well as long term fuel price stability. It has a minimum environmental impact if compared with other conventional desalination processes. The operational expenses of nuclear desalination are far lower than those of conventional plants. implementation of nuclear desalination in Saudi Arabia is essential where large water requirements exist. The CANDU PHWR is the appropriate type of nuclear reactor for Saudi Arabia. A hybrid reverse osmosis/MSF CANDU PHWR is the candidate system for applying dual purpose nuclear desalination plants in Saudi Arabia. (author)
The aims of the present survey were to determine whether differences existed between male and female dentists in Saudi Arabia in career development, positions occupied within their employment, and to analyze the effect of different variables on their career development in some of the provinces in Saudi Arabia. A self-conducted questionnaire was distributed among male and female dentists, general practitioners as well as specialists, working at several governmental hospitals in Saudi Arabia. The questionnaires consisted of 40 questions in the format of multiple choices and yes/no answer. Data were analyzed by gender with the significant difference level set at (P < 0.05). The response rate was 40.8% of which 51.9% were females and 48.1% males with 70% of them below 45 years of age. No significant difference was found between males and females in having higher education or additional degrees. The specialty that was highly reported among females was pedodontics and in males, orthodontics. Males were more likely to hold authorized administrative positions (63%), while females held administrative positions which were internally arranged by their departments (57%). Eighty-three percent of female respondents thought that there was favouritism towards males in appointment to administrative positions, while only 5.5% of male respondents reported that there was favouritism to females in occupying the same positions. There was no significant difference between male and female decant difference between male and female dentists in Saudi Arabia with respect to job opportunities, working hours and relationships with their colleagues. In addition, there is evidence of an intensifying determination of female dentists in Saudi Arabia, to pursue their chosen career while coping with the diverse demands of being a professional, a wife and mother.

Rapid developments in the field of mass spectrometry-based quantitative proteomic technologies holds great promise in the search for clinically useful protein biomarkers for early detection, diagnosis, and prognosis of disease in general, and for monitoring response to therapy. Proteomics may contribute to finding novel drug targets and unravel molecular pathways associated with disease. Despite the application of clinical proteomics to a wide spectrum of disease research globally, however, there is lack of data with regard to quantitative proteomics in the Kingdom of Saudi Arabia (KSA for the diseases common to the Saudi population. In this review therefore, we will discuss some aspects of clinical proteomics with regard to the occurrence of common diseases, and outline our perspectives and vision in the context of KSA. Furthermore, we aim to introduce the concept of a national Saudi Proteomics Society in the Kingdom as part of an advanced research and development program.

Full Text Available To provide a universal basic education, Saudi Arabia initially employed a rapid quantitative educational strategy, later developing a qualitative focus to improve standards of education delivery and quality of student outcomes. Despite generous resources provided for education, however, there is no national assessment system to provide statistical evidence on students’ learning outcomes. Educators are querying the curricula and quality of delivery for Saudi education, especially following low student performances on the Trends in International Mathematics and Science Study (TIMSS in 2003 and 2007. There is a growing demand for national assessment standards for all key subject areas to monitor students’ learning progress. This study acknowledges extant research on this important topic and offers a strategy of national assessment to guide educational reform.

This paper reports that foreign oil companies with concessions in northern Yemen have been drawn into a border dispute between Yemen and Saudi Arabia. At least six companies received letters from the Saudi government warning them that steps, as yet undefined, will be taken if exploration extends into disputed areas. A second territorial dispute also appears to be brewing in the region. Iran has ejected United Arab Emirates nationals from the island of Abu Musa in the Persian Gulf, which is jointly administered by Iran and Sharjah, one of the emirates. The U.A.E. government has reported the situation to the Gulf Cooperation Council, triggering a denial from Iran that anyone has been deported from the island
Full Text Available A small farm of the microalga Spirulina platensis (Nordstedt Geitler was established in Saudi Arabia in 1999. The levels of arsenic (As, cadmium (Cd, copper (Cu, iron (Fe, mercury (Hg, manganese (Mn, lead (Pb and zinc (Zn were measured in the final dry powder of this alga using atomic absorption spectroscopy. The content of As, Cd, Hg and Pb in the dry powder were very low and they ranged between 0.002 mg kg-1 for As and 0.109 mg kg-1 for Pb. Higher levels were found for Cu, Fe, Mn and Zn and they varied between 8.51 mg kg-1 for Cu and 394 mg kg-1 for Fe. The results indicated that the heavy metal content of Saudi Arabian Spirulina is within the recommended range established by major producers.

Rheological characteristics of saudi crude oil emulsions were measured with a Brookfield viscometer at temperatures of 10, 20, 30 and 40C. The Saudi field crude oils used in the present study were: heavy, medium, light and extralight. The emulsion constituents were crude oil, brine, emulsifier (Triton X-100) and dilute hydrochloric acid. The measured data were first classified into two groups for Newtonian and non-Newtonian fluids. The results showed that the non-Newtonian emulsions exhibit pseudoplastic behavior and their rheological characteristics can be described by the power-law model. Then, the effect of dispersed phase (oil) concentration and temperature on the rheological behavior of the emulsions were thoroughly investigated using statistical analysis (t-test). 16 figs., 5 tabs., 13 refs.

This paper reports on the Saudi Arabian Oil Co. (Saudi Aramco), the only operator in the country, that has accelerated its production expansion program aimed at boosting capacity from the current 8.5 million bpd to 10 million bpd. Initially expected to be completed by 1999, it now appears a sustainable 10 million bpd rate may be attainable by 1996. By this time next year, at least nine major onshore projects will have been started as well as five offshore. Included will be development of Hawtah, the initial oil discovery in the Central province south of Riyadh. The program also means significantly increased drilling. In fact, 1991 completions should easily double those of last year
On Aug. 2, 1990, Iraqi forces invaded Kuwait and triggered one of the most severe crises in the world's oil supplies since World War II. Within a few days of the invasion, Iraqi and Kuwaiti oil exports were embargoed, and almost 4.6 million b/d oil of production was removed from world markets. This shortfall amounted to about 20% of total Organization of Petroleum Exporting Countries production at the time and could have proven disastrous to the world's industrial and financial well-being. However, there was no disruption to the major economies of the world. This paper reports that the primary reason for the cushioning of this impact was the massive expansion in production undertaken by Saudi Arabian Oil Co. (Saudi Aramco)

Shifts in Saudi Arabian oil policy are explained by using data covering public revenues and expenditures plus the balance of payments. It is concluded that, according to the target revenue theory, Saudi Arabia only for a very short time after the first and second oil crises was on the backward sloping part of the supply curve. Perhaps Saudi Arabia cut oil production during the two oil crises because it wanted big oil price increases to prevent budget cuts. In any case, it started to increase oil production in the middle of 1985 when its economy was in great imbalance. Furthermore, calculations for the period 1989-2000 reveal that Saudi Arabia will probably face economic problems in the 1990s so that it will not again be OPEC's swing producer. On the contrary, Saudi Arabia will probably increase its share of OPEC's oil production in the 1990s. (author)
Saudi Arabia this year is completing its expansion of production capacity and developing recent discoveries to enhance export flexibility. The 3 million b/d capacity expansion to 10 million b/d, announced in 1989, is on target for completion by year end 1994. Most of the effort involves restoration of mothballed production equipment and installation of several gas-oil separation plants (GOSPs) in existing fields. But Saudi Arabian Oil Co. (Saudi Aramco) also this year will start up production of extra-light oil from a new field in the central part of the kingdom. Start-up of Hawtah area production demonstrates success of an oil search Aramco began after receiving exclusive exploration rights to nearly all of Saudi Arabia's prospective area in 1986. From new fields and traditional producing areas, therefore, Saudi Arabia has the potential to expand production capacity beyond 10 million b/d. The paper describes the development of the extra capacity
The Saudi Cabinet of Ministers approved the Saudi General Environment System (SGES) in 2001. This approval is considered a step forward towards preserving the environment in Saudi Arabia. One of the targets of this system is to make environmental planning as an un-replaceable part of every comprehensive development planning in all industrial, agricultural, and architectural sectors. Achieving such a target requires a specialized labor force. Therefore, College of Engineering should act positively and actively in disseminating environmental awareness among engineers since they play a major rule in development projects. A degree in environmental engineering is a must at present, which is not available yet at any university in Saudi Arabia. Details of a B. Sc degree in environmental engineering offered by two universities in USA, are discussed. The syllabus of a degree in environment engineering adapted for the Saudi environment and culture is outlined
Exercise capacity of Saudi women is less when compared to similar studies in women from other regions. Exercise tolerance test can be used to rule out presence of IHD in Saudi women, but value of a positive test is less likely to predict the presence of IHD.

Full Text Available Only few studies regarding glomerulonephritis, with relatively small numbers of patients, have so far been published from different centers in Saudi Arabia, and have reported conflicting results regarding the patterns, even in the same city. The possible reasons for these differences include the small number of patients in the different studies, differences in the indications for renal biopsies, referral bias, geographical differences, and, sometimes, the non-availability of the necessary diagnostic facilities in the reporting centers. In order to overcome these problems, a registry for glomerulonephropathy was attempted in Saudi Arabia. Six large referral hospitals from different regions of Saudi Arabia participated in this registry. Biopsy reports and clinical information of 1294 renal biopsies were obtained. There were 782 renal biopsies due to glomerulonephritis (GN accounting for 77.2% of the total biopsies. Five hundred eighty seven (72.6% were primary glomerulonephritidis. Focal and segmental glomerulosclerosis (FSGS (21.3% and membrano-proliferative glomerulonephritis (MPGN (20.7% were the most common types found in the primary glomerulonephritidis. Membranous glomerulonephritis (MGN was present in only 10.6% of the cases. IgA nephropathy was found in 6.5% of the cases. Of the secondary glomerulo-nephritides, systemic lupus erythematosus (SLE was the most common indication for biopsy (57.0% and amyloidosis was found in only 3.2% of the biopsies. In conclusion, FSGS and MPGN were the most common forms of primary glomerulonephritis in adult patients in Saudi Arabia. MGN was not as common as in the western world. SLE was the commonest cause of secondary GN. Amyloidosis was not as common as in other Arab countries. There is a need for more centers from Saudi Arabia to join this national GN registry. Similar registries can be established in different Arab countries, which all would, hopefully, lead to a Pan-Arab GN registry.
Full Text Available The aim of this study was to evaluate iron deficiency anemia among adult healthy Saudi males and adult healthy non-pregnant Saudi females in Riyadh City, Saudi Arabia. 234 healthy adults were recruited of which, 102 were females and 132 were males. Male subjects were reclassified to cigarette smokers (n = 52 and non-smokers (n = 80. Anemia was assessed by dietary iron intake, hemoglobin and hematocrit levels. Iron intake was measured by analyzing the intake of three consecutive days. The results showed that iron intake, hemoglobin and hematocrit levels were significantly higher in males compared to females. Mean iron intake of males (13.6±3.1 mg/day was adequate compared to DRI recommendation. Mean concentrations of hemoglobin (15.89±0.95 g/dL and hematocrit (47.7±3.6% for males were normal. Hemoglobin and hematocrit levels were significantly higher in smokers compared to non-smokers, but both were normal, which suggested that iron deficiency anemia is not found among adult Saudi males. Mean iron intake of females (10.2±2.8 mg/day was inadequate compared to DRI recommendation. Mean hemoglobin level (13.68±0.83 g/gL and mean hematocrit level (38.9±3.2% of females were lower than cutoff values for determining iron deficiency anemia. Based on hemoglobin and hematocrit values, 21.6% and 20.6% of female participants, respectively were anemic. Based on iron intake, 95.1% of female participants had intake lower than the recommendation. Results of this study illustrated that iron deficiency anemia is highly prevalent among adult Saudi women in Riyadh City and suggests actions to eradicate iron deficiency anemia. These actions include increasing nutritional awareness and education for the purpose of changing inappropriate consumption patterns as well as fortification of certain foods in combination with additional intakes of iron from supplements.

Full Text Available Abstract Background Data on sexually transmitted infections (STIs in Saudi Arabia (SA and other Islamic countries are limited. This study describes the results of a five-year surveillance for STIs in SA. Methods This is a case series descriptive study of all confirmed STIs diagnosed in SA from January, 1995 through December, 1999. Results A total of 39049 STIs were reported to the Ministry of Health. Reported STIs included nongonococcal urethritis (14557 infections, 37.3%, trichomoniasis (10967 infections, 28.1%, gonococcal urethritis (5547 infections, 14.2%, syphilis (3385 infections, 8.7%, human immunodeficiency virus (2917 infections, 7.5%, genital warts (1382, 3.5%, genital herpes (216 infections, 0.6%, and chancroid (78 infections, 0.2%. The average annual incidence of STIs per 100,000 population for Saudis and non-Saudis, respectively, was as follows: 14.8 and 7.5 for nongonococcal urethritis, 9.4 and 10.4 for trichomoniasis, 5.2 and 4.2 for gonorrhea, 1.7 and 6.4 for syphilis, 0.6 and 8.0 for HIV, 1.4 and 0.7 for genital warts, 0.1 and 0.4 for genital herpes, and 0.1 and 0.1 for chancroid. The incidence of STIs was somewhat steady over the surveillance period except for nongonococcal urethritis which gradually increased. Conclusion Nongonococcal urethritis, trichomoniasis, and gonococcal urethritis were the most commonly reported STIs in SA. Even though the incidence of STIs in SA is limited, appropriate preventive strategies that conform to the Islamic rules and values are essential and should be of highest priority for policymakers because of the potential of such infections to spread particularly among the youth.

The Najd Fault System of the Arabian-Nubian Shield is considered to be the largest Proterozoic Shear zone system on Earth. The shear zone was active during the late stages of the Pan African evolution and is known to be responsible for the exhumation of fragments of juvenile Proterozoic continental crust that form a series of basement domes across the shield areas of Egypt and Saudi Arabia. A three year research project funded by the Austrian Science Fund (FWF) and supported by the Saudi Geological Survey (SGS) has focused on structural mapping, petrology and geochronology of the shear zone system in order to constrain age and mechanisms of exhumation of the domes - with focus on the Saudi Arabian side of the Red Sea. We recognise important differences in comparison with the basement domes in the Eastern desert of Egypt. In particular, high grade metamorphic rocks are not exclusively confined to basement domes surrounded by shear zones, but also occur within shear zones themselves. Moreover, we recognise both exhumation in extensional and in transpressive regimes to be responsible for exhumation of high grade metamorphic rocks in different parts of the shield. We suggest that these apparent structural differences between different sub-regions of the shield largely reflect different timing of activity of various branches of the Najd Fault System. In order to tackle the ill-resolved timing of the Najd Fault System, zircon geochronology is performed on intrusive rocks with different cross cutting relationships to the shear zone. We are able to constrain an age between 580 Ma and 605 Ma for one of the major branches of the shear zone, namely the Ajjaj shear zone. In our contribution we present a strain map for the shield as well as early geochronological data for selected shear zone branches.

The new economic trends of Saudi Arabia are detailed in this article. This country can take an important place on the world petroleum market in the future; he has the quarter of world petroleum reserves, and is determined to keep its place of first petroleum exporter. New developments projects are arising: electric power, telecommunications, civil aviation, seawater desalination. In terms of financing, as the state cannot finance all these new projects, new means are used: privatisation, BOT (build-operate-transfer) contracts, and offset programs. (N.C.)
The Kingdom of Saudi Arabia has numerous large monogenetic volcanic fields, known locally as "harrats." The largest of these, Harrat Rahat (Figure 1), produced a basaltic fissure eruption in 1256 C.E. with lava flows traveling within 20 kilometers of the city Al-Madinah, which currently has a population of 1.5 million plus an additional 3 million pilgrims annually. With more than 950 visible vents and periodic seismic swarms, an understanding of the risk of future eruptions in this volcanic field is vital.

ABSTRACT The incidence of Genito-urinary cancer (GUC) in the Kingdom of Saudi Arabia (KSA) increases with age and is 5-fold higher in men than in women. Genito-urinary cancer accounts for only 9.2% of all cancers in KSA, while the rate in the United States of America (USA) is as high as 24.1%. An epidemiological search on GUC in KSA revealed a relatively low incidence compared to developed countries. This is more evident in prostatic cancer, which is 50 times lower ...

Objective was to report on the prognosis, neurologic outcome, and recurrence of stroke in Saudi children. We evaluated a cohort of 104 Saudi children with stroke at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia from July 1992 to February 2001 (retrospective study) and February2001 to March 2003 (prospective study). We analyzed the salient clinical, neuroimaging, neurophysiological, neuropsychological and laboratory data following retrieval from a specially designed comprehensive protocol. Of the 104 children in the cohort (aged one month to 12 years), 5 (4.8%) died during the study period and 9(8.7%) were lost to follow-up. The mean duration of follow-up for the remaining 90 children was 40 months (median 33 months). Recovery was judged complete in 6(6.7%) of these 90 children. We detected residual hemiparesis (irrespective of its effect on daily functions) in 73 (81%) and this was combined with other motor deficits in 45 children (50%). Forty-one children (46%) had residual dysphasia or language deficits, whereas 45 (50%) were judged to have had cognitive deficit. Psychometry revealed an abnormal intelligence quotient test (70) in 19 of 26 (73%) children. Other neurologic sequelae included epilepsy in 52 (58%), recurrent headaches in 13 (14%) and hydrocephalus in 4 (4.4%) patients, Six of the 95 (6.3%) children, who were ascertained to have died or kept their follow-up, had one ave died or kept their follow-up, had one or more occurrences, one month to 5 years after initial stroke (median 23 months). Patients who had recurrent strokes were significantly more likely to be the product of consanguineous marriages (p=0.04). Regarding the group of 23 children with perinatal stroke, neither deaths nor recurrences occurred during the follow-up period. However, 20 (87%) of them had significant delays in their developmental milestones. The toll of stroke in Saudi children is demanding, with most children demonstrating persistent neurologic or cognitive deficits. Primary prevention for recurrences is feasible through informed genetic counseling. (author)

Full Text Available This article, which opens a new line of research, is intended to make a first assessment of the consequences of Indonesian migration to saudi Arabia, in particular during the first half of the 2Oth century-a period when the immigration is bound up with the pilgrimage from which Saudi Arabia draws a large part of its revenues. It must be added that while documentary evidence and partial studies on this period exist, it turns out that documentation on the contemporary period is scarce. This article also is concerned with describing the evolution of certain striking aspects of the close relation between the pilgrimage to Mecca and Indonesian migrants looking for work. We need to consider the methods of hiring labor, the networks involved in recruiting it, the organization of travel, as well as the increasing indebtedness of the migrants through intermediaries who, more and more professionally, arrange these attempts to live abroad, prompted in many cases by the same desire for wealth.Copyright (c 2014 by SDI.

Full Text Available Islamic trend in Saudi Arabic poetry is distinct from others due to several reasons. It includes the influence of imam, preacher and reformer Mohammad bin Abdul Wahab on whose call different geographical areas like Najd and Hejaz were unified and the state/kingdom came into existence 84 years ago. The constitution of the country is based on the doctrine of Islam and Sharia (Islamic law since its inception and Islamic culture is still valid, explicit and rigorous. The unified kingdom, since the days of its founder King Abdul Aziz Al-Saud, has been protected from the evil of the colonialists who were resisted not only in exporting their arms and men but their ideas were also fought tooth and nail. They were unable to spread the missionary schools, through which they preach their philosophy. The Orientalists were also kept at bay and the so-called liberals did not publish their ideas boldly and openly and were unable to influence the thought process of Saudi intellectuals.

The objective of this study was to identify various stress factors affecting dentists and to evaluate their stress manifestations and stress management. A questionnaire was distributed among dentists residing in Jeddah, Saudi Arabia. The questionnaire classified stress factors into professional, patient-related, dental procedure-related, and office management factors. Sign and symptoms of stress manifestations and management were also evaluated. The sample included 80 females and 75 males, with 47% of them below the age of 30 years. Out of the total sample, the largest percentage (60.6%) were general practitioners, 47.7% had experience of less than 5 years and 32.2% had 11 years of experience. The highest mean scores of stress were related to professional factors and dental procedure-related factors. Among those, the main significant factors that caused stress in the surveyed sample were lack of time in relation to workload (76.1%), limited visibility and accessibility (67.7%). The most common manifestations of stress were nervousness (95%), musculoskeletal fatigue (72%) and anger (58%). Dentists predominantly managed their stress by praying and reading holy books (80%) and by spending time alone (75%) or with family and friends (70%). The most prevalent and significant causes of stress among dentists working in Jeddah, Saudi Arabia were professional in nature. Stress has been manifested by nervousness and musculoskeletal problem and was mainly managed by praying and lem and was mainly managed by praying and spending time alone or with family and friends.

Full Text Available This is a study performed to identify the risk factors for gallstones in Saudis, taking the patient population of King Khalid University Hospital as a sample. Only Saudis with symptomatic gallstones were studied, the parameters being age, sex, weight, body mass index, fertility, age at menarche and age at marriage. The results showed that sex, weight, body mass index and fertility all appeared to be important factors in the development of gallstones and that the condition affects more Saudi females and at a younger age than reported in the literature, probably due to overweight and factors related to reproductivity. We conclude that gallstones are common in Saudi women and affect them at a younger age than western women, weight and fertility appear to be important risk factors.

Full Text Available The main purpose of this research was to gain an understanding of the adoption behavior of mobile computing in Saudi Arabia. In particular, it aimed to acquire new insight into mobile computing trends, specifically in Saudi Arabia, in order to develop hypotheses and formulate precise criteria for mobile computing evaluation. In order to achieve these aims, the researcher created a focus group by recruiting eight participants with solid background knowledge of usability engineering and mobile computing. The focus group proposed a four-phase process: determination, qualification, categorization and evaluation of the mobile computing applications developed by Saudi organizations. During the determination phase, two hundred and twenty seven (n=227 mobile applications were determined as having been developed by organizations in Saudi Arabia. During the qualification phase, one hundred and forty two (n=142 mobile applications were qualified. Within the categorization phase, the experts categorized only the qualified applications into a two-level categorization hierarchy. Finally, in the evaluation phase, the qualified applications were evaluated in terms of purpose, platform, visual appearance, content, organization and usability. The results herein revealed that 43% of the mobile applications in Saudi Arabia were M-Government applications, while 57% were M-Business applications. In addition, the study proposed a sample of thirty six (n=36 applications as having statistical significance from all of the mobile applications in Saudi Arabia.

This paper aims at presenting details of the application of assisted reproductive technology and the impact of the Islamic law (Sharia on its practice in the Kingdom of Saudi Arabia (KSA. Analysis of the data sourced from manual searches of bibliographies from key articles showed that this technology in KSA is practiced in a strictly religious manner and certain aspects of the technology are completely forbidden. It further showed that lack of an official government in-vitro fertilization (IVF registry to gather information on the activities of IVF clinics has limited the data available for international comparisons. Sharing information internationally could allow religiously concerned infertile couples to have access to the reproductive services in the Kingdom. It would further improve the quality of care, enhance certain techniques like in-vitro maturation and experimentation on embryos, by providing resources that are currently unavailable, keeping in view the religious beliefs and avoiding conflicts.

Natural background radiation measurements have been made at numerous locations throughout the world. Little work in this field has been done in developing countries. In this study, the external exposure rates due to natural background radiation sources have been measured for different Saudi Arabian cities. Thermoluminescence dosimeters, CaF2Dy(TLD-200), has been used for field measurements. Exposure to TLD's response correlations were obtained for each TLD using a 137Cs source. A correlation of TLD's response fading at a continuous radiation exposure environment was obtained and applied to correct field measurements. The measurements were taken every two months for a total of six intervals during the whole year. The average measurements of outdoor external exposure rates was found to vary between a minimum of 5.29 ?R h-1 in Dammam city and a maximum of 11.59 ?R h-1 in Al-Khamis city. (1 fig., 1 tab.)

A total of 2,515 individuals attending a large military hospital in Saudi Arabia who had appropriate radiologic evidence of treponematosis were studied clinically and serologically. The indications are that nonvenereal treponematosis (bejel) exists in considerable numbers among the nomadic communities living in rural areas. In contrast, venereal syphilis is less common in this population and is found almost exclusively in urban populations. Some of the high-risk regions for bejel have been identified. Many individuals from nomadic communities complained of persistent pain in the lower limbs, which was often associated with radiologic evidence of osteoperiostitis of the long bones. It also appears that within the last 30 years bejel has become clinically attenuated, with the majority of seropositive individuals having latent disease. A hypothesis is put forward that persistent lesions are sustained by superinfection and that improvements in hygiene have resulted in a decrease in the incidence of reexposure. Measures to control the infection are outlined. PMID:4012169

Full Text Available Background and Objectives: The blood donor system in the Kingdom of Saudi Arabia depends on a combination of voluntary and involuntary donors. The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation. Materials and Methods: The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517 and nondonors (n = 316, between February and June 2008. All were males. Results: Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5% and lack of time (16% as their main deterrents. Reasons for rejection as donors include underweight and age (71% and health reasons (19%. Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood. Conclusion: These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

Full Text Available Glomerulonephritis (GN is one of the leading causes of end-stage renal disease. A good understanding of its pattern and prevalence as well as exploration of effective therapeutic strategies for protecting the glomerulus, would have tremendous impact on public health. In the Kingdom of Saudi Arabia (KSA, focal and segmental glomerulo sclerosis (FSGS is the commonest type of primary glomerular diseases (PGD encountered in clinical practice. Its prevalence varies from less than 4% in Gizan, in the southern part of KSA, to approximately 35% in Riyadh, central Saudi Arabia. In our experience, the nephrotic syndrome was the commonest mode of presentation of FSGS. Response to corticosteroid therapy is generally poor and the mortality rate is high. Mesangioproliferative GN is the second most common GN constituting up to 25% of PGD in our experience. Other researchers from different parts of the Kingdom, however, have given prevalence rates ranging from 8 to 57.1%. The reported prevalence of Immunoglobulin-A nephropathy (IgAN in KSA ranges from 5.8% to 13.6%. It is more common in the elderly, and men are affected more often than women. In contrast to KSA, IgAN is the commonest PGD in Japan, China, Hong Kong, Singapore and Taiwan. Membranous GN (MGN is less common in KSA than encountered elsewhere, the prevalence ranging from 3.9 to 21.8%. Nephropathy secondary to systemic diseases are also common in KSA. Lupus nephritis (LN accounted for 48.5% of secondary glomerular diseases (SGD with the combination of WHO classes III and IV (aggressive types of LN accounting for 56% of all patients. LN is another disease where differences in racial susceptibility may account for the uneven distribution. Post-streptococcal GN seems to be declining in frequency in KSA, the reported prevalence ranging from 2.7% to 2.9%.

This dissertation consists of three chapters. Chapter one presents a theoretical model using a dynamic stochastic general equilibrium (DSGE) approach to investigate the role of world oil prices in explaining the business cycle in Saudi Arabia. This model incorporates both productivity and oil revenue shocks. The results indicate that productivity shocks are relatively more important to business cycles than oil shocks. However, this model has some unfavorable features that are associated with both investment and labor hours. The second chapter presents a modified theoretical model using DSGE approach to examine the role of world oil prices versus productivity shocks in explaining the business cycles in Saudi Arabia. To overcome the unfavorable features of the baseline model, the alternative model adds friction to the model by incorporating investment portfolio adjustment cost. Thus, the alternative model produces similar dynamics to that of the baseline model but the unfavorable characteristics are eliminated. Also, this chapter conducts sensitivity analysis. The objective of the third chapter is to empirically investigate how real world oil price and productivity shocks affect output, consumption, investment, labor hours, and trade balance/output ratio for Saudi Arabia. This chapter complements the theoretical model of the previous chapters. In addition, this study builds a foundation for future studies in examining the impact of real world oil price shocks on the economies of key trade partners of Saudi Arabia. The results of the third chapter show that productivity shocks matter more for macroeconomic fluctuations than oil shocks for the Saudis' primary trade partners. Therefore, fears of oil importing countries appear to be overstated. As a whole, this research is important for the following reasons. First, the empirical model is consistent with the predictions of our theoretical model in that productivity is a driving force of business cycles in Saudi Arabia. Second, the policymakers in Saudi Arabia should be more concerned with increasing productivity through adopting new technologies that increase economic prosperity. Therefore, the policymakers should continue diversifying economic resources and reduce their reliance on oil.

The first report of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Saudi population of the Eastern Province paved the way for extensive investigations to determine the distribution and molecular pathogenesis of G6PD deficiency in Saudis in different parts of the country. During a national study lasting from 1980 to 1993, 24,407 Saudi in 31 different areas of Saudi Arabia screened for G6PD deficiency using spectrophoretic estimation of enzyme activity and electrophoretic separation of the phenotypes. The results in the males and females were separately analyzed and showed a statistically significant difference in the frequency in the male (0.0905) and female (0.041) population (P<0.05). The frequency in the male varied from 0 to 0.398 and in the female from 0 to 0.214. The phenotypes identified included G6PD-A, G6PD-Mediterranean and G6PD-Med-Like with G6PD-B as the normal phenotype in all areas. This study shows that G6PD deficiency is a frequently identified single-gene disorder in Saudi Arabia and G6PD-Mediterranean is the major variant producing the severe deficiency state in this population.

Abstract The current treatment of psoriasis patients with biologic agents in the Kingdom of Saudi Arabia (KSA) is mainly based on clinical experience. Although there are published international guidelines for treatment with biologics, such as the European S3 guidelines (a joint project of the European Dermatology Forum, the European Academy of Dermatology and Venereology, and the International Psoriasis Council), many nations have found it beneficial to develop country-based guidelines that incorporate specific regional aspects of therapy (legal and practical). With the expanded role of biologic agents in the treatment of psoriasis in Saudi Arabia, a need for local Saudi guidelines has become evident. Here we present a practical approach to the evidence-based clinical administration of biologics for professionals who treat patients with psoriasis. PMID:25075955

Full Text Available The objective of this study is to determine the presence of Helicobacter pylori in the dental plaque of healthy Saudis and its relation to dental care. One hundred randomly selected healthy Saudis attending the dental clinic were assessed for oral hygiene and periodontal disease by dental examination. Information about the use of toothpaste, chewing stick, smoking and dentures was obtained. Samples of dental plaque were collected after scoring it according to the plaque index. Presence of H. pylori in the plaque was sought by a commercially available rapid urease test with a sensitivity of 94% and a specificity of 100%. The presence of H. pylori was indicated by a positive rapid urease test in 81 %. There was significant correlation of heavy dental plaque (plaque index score 3 with presence of H. pylori (p=0.03. We conclude that H. pylori is present in the dental plaque of most Saudis and this is due to poor oral hygiene.
Full Text Available Our goal in this paper is to explorethe validity of Wagner’s Law in Saudi Arabia during the period (1970-2012 for real oil GDP and Non-oil GDP.Wagner’s Law investigated that fundamental economic growth is validity to the public sector growth. In the previousstudies have been tested the six versions of Wagner’s law to support the existence of long-run relationship between government expenditure and economic growth.We used a method as a time series econometrics techniques to examine how far Wagner’s Law validity can be applied in Saudi economy. The results obtained from the analyses find that the Wagnerian proposition can explain the growth of government in Saudi Arabia, which holds for both the oil and non-oil income cases. The findings also note that the existence of strong causality for all of Wagner’s law versions in the long run.

Full Text Available This study is a comparison of gamma ray linear attenuation coefficient of two typs of shielding materials made of Saudi white and red sand. Each shield was consisted of one part of cement two parts of sand in addi-tion to water. Different thicknesses were tested. The concentrations of all elements in each shield material were determined by Inductively Coupled Plasma Mass Spectrometer (ICP-MS. The results obtained from the ICP-MS were used in MCNP4B (Monte Carlo N-Particle Transport Computer Code System  to calculate the attenuation coefficient. The theoretical (MCNP4B and the experimental calculations were found to be in a good agreement. In the casw of the largest thickness used, 28cm, the gamma ray intensity passing through the white sand shield was approximately half of the intensity obtained through the red sand shield. The average linear attenuation coefficients were found to be 0.17cm-1 and 0.15cm-1 for white and red sand shields respectively. The study shows that white sand is better for attenuating gamma ray compared to the red sand.
Measurements of radon exhalations from nine selected rocks collected from areas of high background radioactivity in the Western Province of Saudi Arabia were taken using a radon gas analyzer. The ? background dose rates near the ground in the areas were in the range of 110-2400 nSv/hr. The rocks were used in the construction of single floor homes. Small pieces of each rock were gridded to powder for radon exhalation measurements. Most of the rocks were grinded. It was found that the final radioactivities of emanated radon per unit mass of the rock varied from 0.617 Bq.kg-1 to 113 Bq.kg-1 with an average of 43.2 Bq.kg-1 while the powder's values varied from 8.01 Bq.kg-1 to 232 Bq.kg-1 with an average of 93.8 Bq.kg-1. The linear correlation coefficient between emanated radon from rocks and powders was 0.932. Therefore, these rocks can be a significant source of indoor radon as well as external ?-radiation from the uranium decay series. (author)

Full Text Available Purine nucleoside phosphorylase (PNP deficiency is a rare autosomal recessive metabolic disorder that results in combined immunodeficiency, neurologic dysfunction and autoimmunity. PNP deficiency has never been reported from Saudi Arabia or in patients with an Arabic ethnic background. We report on two Saudi girls with PNP deficiency. Both showed severe lymphopenia and neurological involvement. Sequencing of the PNP gene of one girl revealed a novel missense mutation Pro146>Leu in exon 4 due to a change in the codon from CCT>CTT. Expression of PNP (146L cDNA in E coli indicated that the mutation greatly reduced, but did not completely eliminate PNP activity.

The IFDA computer code, based on the fuzzy set theory is applied. Results reveal that the FNR reactor is the best alternative for the case of Saudi Arabian nuclear research facility, and MITR is the second best. 17 refs
Polyoma virus nephropathy (BK virus) is being recognized as an important cause of graft failure. It is usually confused with acute rejection. No cases have been reported from the kingdom of Saudi Arabia. We report a case of a Saudi gentleman, who was transplanted outside the country, with persistently elevated creatinine and urethral stenosis. He was treated for acute rejection on more than one occasion with no significant improvement in his renal function. Polyoma virus nephropathy was diagnosed by detecting the virus DNA by the polychain reaction techniques (PCR). The patient's renal function stabilized after the calcineurin inhibitors were discontinued. (author)
Full text: Undoubtedly, easy availability of radiopharmaceuticals is a key element in application of radioisotopes in health care. And, creating self-sufficiency within the country and the geographical region in manufacturing these time-limited products further enhances this prospect. For obvious reasons, on demand availability and timely distribution of products bodes well for a regional programme. At King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, one such programme began in early 1980s with the installation of the CS-30 (26.4 MeV) cyclotron, with an intention not only to make available the cyclotron products for medical imaging, but also to establish a contemporary research programme in radiotracer development as exemplified by simultaneous installation of a Tomogram (PET scanner) at the time when PET scanning was in its infancy. The first beam on target in 1982 produced the first batch of 67Ga citrate radiopharmaceutical, followed by an addition of various other cyclotron based products over the years. Presently, the Cyclotron Facility routinely produces six cyclotron isotopes (201Tl, 67Ga, 81mKr, 123I, 18F and 13N) which are subsequently formulated into nine different radiopharmaceuticals. Weekly, approximately 25 batches of radiopharmaceuticals are manufactured supporting 35 nuclear medicine facilities within the country and the geographical region. A key montry and the geographical region. A key motivating and driving force for our Centre has been the goal of becoming a comprehensive radiopharmaceuticals manufacturing facility. Consequently, we introduced in Year 2000 the 131I based products for diagnosis as well as for therapy, including on-request manufacturing of 131I labeled mIBG. Good Manufacturing Practice is the cornerstone of any radiopharmaceuticals manufacturing program. KFSH and RC is a perfect example of how this operational and guiding principle has been applied and evolved over the years, culminating into an effective quality management system for manufacturing radiopharmaceutical products consistently conforming to specifications. The programme building has been 'work in progress' from the onset and continues to be so, particularly in establishment and implementation of strict operational philosophy of GMP and ISO quality management system. We also realized that people are the most important component of any viable program. For efficient functioning, the staff must be well qualified and appropriately trained to achieve the mission of the organization. This has been achieved through staff selection based upon educational background, followed by extensive on-the-job training, as well as didactic education. Consequently, our facility has had a good mix of young and experienced staff. Furthermore, we have availed of the various IAEA's programmes in specific training and fellowships for in depth exposure to other centres. With embarkation upon new programs, continuing education remains a central theme in ultimate success of the entire program. The experience gained over two decades of continuous operation breeds confidence in the staff to achieve the goal of making Saudi Arabia self-sufficient in all its radiopharmaceuticals needs. Continuing with our commitment to make available to the peoples of the country the most contemporary imaging modality, PET scanner was installed at KFSH and RC in 1995. Along with the routine PET work, we have established a team of scientists to perform research work in developing new radiotracers. KFSH and RC's cyclotron facility has continually focused on an overwhelming goal of becoming a comprehensive radiopharmaceuticals manufacturing facility. To this end, the year 2005 is the beginning of establishing just one such facility through expansion of the program that entails: a new building; a state-of-the-art cyclotron (30 MeV; plus a small cyclotron dedicated for PET isotopes production); advanced clean rooms; more importantly, the establishment of the Tc-99m Generators and Cold Kits manufacturing programs.

Skin lipids play an important role in the regulation of cutaneous water loss (CWL). Earlier studies have shown that Saudi desert birds exhibit a tendency of reduced CWL than birds from temperate environment due to adaptive changes in composition of their skin lipids. In this study, we used thin-layer chromatography (TLC) for separation and detection of non-polar and polar lipids from the skin of six bird species including sooty gull, brown booby, house sparrow, Arabian waxbill, sand partridge, and laughing dove. The lipids were separated and detected on Silica gel G coated TLC plates and quantified by using densitometric image analysis. Rf values of the non-polar lipids were as follows: cholesterol (0.29), free fatty acids (0.58), triacylglycerol (0.69), fatty acids methyl esters (0.84) and cholesterol ester (0.97). Rf values for the polar lipids were: cerebroside (0.42), ceramide (0.55) and cholesterol (0.73). The results showed the abundance of fatty acids methyl esters (47.75-60.46%) followed by triacylglycerol (12.69-24.14%). The remaining lipid compositions were as follows: cholesterol (4.09-13.18%), ceramide (2.18-13.27%), and cerebroside (2.53-12.81%). In conclusion, our findings showed that TLC is a simple and sensitive method for the separation and quantification of skin lipids. We also reported a new protocol for lipid extraction using the zirconia beads for efficient disruption of skin tissues. This study will help us better understand the role of skin lipids in adaptive physiology towards adverse climatic conditions. PMID:24600311

A nationwide survey was carried-out aiming at determination of immunization coverage level against the six killer diseases of childhood (tuberculosis, diphtheria, pertussis, tetanus, poliomyelitis, and measles). Variations between geographical zones, urban-rural settings, age, education and mother's employment, father's education, and child's birth order were studied. The standard WHO cluster technique was used. The sample (1102 children) was restricted to Saudi children 1-2 years old. Interviewers were exposed to training and methods of calibration, and involved in a pilot survey. Nationally, the survey showed very high coverage levels, BCG was the highest (99 per cent), measles was the lowest (90 per cent), whereas the three doses of DPT (diphtheria, pertussis and tetanus) and TOPV (trivalent oral polio vaccine) were in between (98, 96 and 94 per cent, respectively). There was no marked differences between urban-rural settings. The western zone showed the lowest coverage by all vaccines. The national coverage by the six vaccines reached 86 per cent correctly immunized (according to WHO standards), 14 per cent partially immunized and 1 per cent non-immunized. Immunization coverage was higher for children to younger mothers. The non-immunized group belonged exclusively to illiterate mothers (1 per cent). Children to mothers with basic education showed the highest coverage (88 per cent). Birth order had negative effect on coverage. Nationally, 88 per cent of children had immunization certificate while 12 per cent had not. The eastern and central zones had the highest percentages of children with certificates (92 and 91 per cent, respectively).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8568952

A considerable number of studies have investigated the relationship between perceptions of organizational justice and employees’ work attitude. This study investigates the effect of distributive justice, procedural justice and interactional justice on supervisor support, organization support, supervisor trust and organization trust in Saudi companies. A questionnaire was used to assess the different relationships. Different results were found confirming or rejecting the different hypotheses.
Little is known about the geographic distribution of common cancers in Saudi Arabia. We explored the spatial incidence patterns of common cancers in Saudi Arabia using spatial autocorrelation analyses, employing the global Moran's I and Anselin's local Moran's I statistics to detect nonrandom incidence patterns. Global ordinary least squares (OLS) regression and local geographically-weighted regression (GWR) were applied to examine the spatial correlation of cancer incidences at the city level. Population-based records of cancers diagnosed between 1998 and 2004 were used. Male lung cancer and female breast cancer exhibited positive statistically significant global Moran's I index values, indicating a tendency toward clustering. The Anselin's local Moran's I analyses revealed small significant clusters of lung cancer, prostate cancer and Hodgkin's disease among males in the Eastern region and significant clusters of thyroid cancers in females in the Eastern and Riyadh regions. Additionally, both regression methods found significant associations among various cancers. For example, OLS and GWR revealed significant spatial associations among NHL, leukemia and Hodgkin's disease (r² = 0.49-0.67 using OLS and r² = 0.52-0.68 using GWR) and between breast and prostate cancer (r² = 0.53 OLS and 0.57 GWR) in Saudi Arabian cities. These findings may help to generate etiologic hypotheses of cancer causation and identify spatial anomalies in cancer incidence in Saudi Arabia. Our findings should stimulate further research on the possible causes underlying these clusters and associations. PMID:24351742

Saudi Aramco pipelines network transports hydrocarbons to export terminals, processing plants and domestic users. This network faced several safety and operational-related challenges that require having a more effective Pipelines Integrity Management System (PIMS). Therefore Saudi Aramco decided to develop its PIMS on the basis of geographical information system (GIS) support through different phases, i.e., establishing the integrity management framework, risk calculation approach, conducting a gap analysis toward the envisioned PIMS, establishing the required scope of work, screening the PIMS applications market, and selecting suitable tools that satisfy expected deliverables, and implement PIMS applications. Saudi Aramco expects great benefits from implementing PIMS, e.g., enhancing safety, enhancing pipeline network robustness, optimizing inspection and maintenance expenditures, and facilitating pipeline management and the decision-making process. Saudi Aramco's new experience in adopting PIMS includes many challenges and lessons-learned associated with all of the PIMS development phases. These challenges include performing the gap analysis, conducting QA/QC sensitivity analysis for the acquired data, establishing the scope of work, selecting the appropriate applications and implementing PIMS.

This paper reports on Saudi Arabian Oil Co. that has jumped its crude oil production 29% to an average 6,257,600 b/d last year. That was Saudi Arabia's response to Iraq's Aug. 2, 1990, invasion of Kuwait and the ensuing Persian Gulf crisis with its United Nations embargo on Iraqi and Kuwaiti oil exports. It was Saudi Aramco's biggest average crude oil volume since the 6,327,220 b/d gauged in 1982, according to the company's 1990 annual report. By the end of 1990 Saudi Aramco's maximum sustained production capability was 8.5 million b/d of crude. To meet long term demand, it decided to advance the timetable and increase the scope of a crude oil expansion program adopted in 1989. Reserves at the end of the year were 257.9 billion bbl of crude and 180.5 tcf of dissolved, associated, and non-associated natural gas, compared with 257.5 billion bbl and 180.355 tcf at yearend 1989

Full Text Available Background and Objective : There is limited information on overweight and obesity in Saudi children and adolescents. The objective of this study was to establish the national prevalence of overweight and obesity in Saudi children and adolescents. Methods : The 2005 Saudi reference data set was used to calculate the body mass index (BMI for children aged 5 to 18 years. Using the 2007 WHO reference, the prevalence of overweight, obesity and severe obesity were defined as the proportion of children with a BMI standard deviation score more than +1, +2 and +3, respectively. The 2000 CDC reference was also used for comparison. Results : There were 19 317 healthy children and adolescents from 5 to 18 years of age, 50.8% of whom were boys. The overall prevalence of overweight, obesity and severe obesity in all age groups was 23.1%, 9.3% and 2%, respectively. A significantly lower prevalence of overweight (23.8 vs 20.4; P < .001 and obesity (9.5 vs 5.7; P < .001 was found when the CDC reference was used. Conclusions : This report establishes baseline national prevalence rates for overweight, obesity and severe obesity in Saudi children and adolescents, indicating intermediate levels between developing and industrialized countries. Measures should be implemented to prevent further increases in the numbers of overweight school-age children and adolescents and the associated health hazards.

This article sets out to analyse the Saudi gas initiative in the context of the decision-making process in Saudi Arabia between 1998 and 2002. It describes the overall context in which the initiative was made. It focuses on the personalities and institutions that were important in its birth and its evolution. The article argues that a mixture of personalities (especially that of Crown Prince Abdullah and foreign minister Saud al-Faisal) and institutions (especially a clutch of new bodies formed in 1999 and 2000) were pivotal in the emergence of the initiative. It also looks at the obstacles that were placed in the way of the initiative, arguing that Saudi Aramco and the minister of oil, Ali Naimi, were key blocking players. Over time, the Saudi gas initiative has come to be seen as a benchmark of the wider cause of economic liberalization in the Kingdom. The lack of progress in the initiative since the initial indicative contract awards in June 2001 has reflected the lack of movement in the general reformist strategy

Full Text Available Objectives: To determine the prevalence of caries in the primary and permanent teeth in a Saudi population. Methods: This study was conducted at the College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia. In June 2010, a literature search was started and found all studies conducted in Saudi Arabia on dental caries from 1999 to 2008. Sixty articles were found on PubMed, which had been published during the considered time period. Sixteen studies were passed through inclusion criteria and included in analysis. A 2 to 12-year-old Saudi population was included to determine the prevalence of caries in primary teeth, and for permanent teeth, the age range was 6-18 years. Results: The prevalence of caries in primary and permanent teeth were analyzed separately. Forest plot and Chi-square test revealed considerable heterogeneity. A random effect model was used to find caries prevalence in primary and permanent teeth. The mean decayed, missing and filled teeth (dmft was 5.38 (95% CI: 4.314 - 6.436, and in the permanent teeth the DMFT was 3.34 (95% CI: 1.97 - 4.75. Publication bias diagnostics suggested possible overestimation of caries prevalence in permanent teeth but not in primary teeth. Conclusion: The results in this study present a high decayed, missing, and filled teeth score in the adult and young population of Saudi Arabia, however, more published data is required as the results obtained from this meta analysis may not give a true picture, and reality may be worse.

Aim: To report the prevalence of impacted third molars according to the age, gender and type among Saudi population. Materials and methods: This retrospective study involved 3800 panoramic radiographs of subjects aged 18 to 45 years who presented to the College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia for oral care during the period from February 2009 to February 2011. Data collected was entered into a spreadsheet (Excel 2000; Microsoft, US) and analyzed using Statistical Package for Social Sciences (SPSS) version 16.0. Results: A total of 713 impacted teeth were identified (18.76%) (p=0.003). The male to female ratio with impacted third molars was 604:109 (5.54:1) and the ratio of patients with impacted teeth was (5:1). Age group 1 (i.e., 20 to 25 years)had the highest prevalence of third molar tooth impaction (64.5%) and this decreased with increasing age. Conclusion: Incidence of tooth impaction is higher in the mandible than in maxilla. Males had a higher incidence of third molar impaction as compared to the females. Highest incidence is found in the age group of 20-25 years. Mesio-angular impaction was the most predominant type. How to cite this article: Syed KB, Kota Z, Ibrahim M, Bagi MA, Assiri MA.

Full Text Available This paper investigates how two important research streams, namely Leadership Styles (LS and Organizational Learning (OL, might be related. In other words, LS and OL represent two rich lines of research: one is about how people lead and the other is about how people learn. Specifically, this contribution addresses two issues (1 the evaluative attitudes of the employees towards LS and OL and (2 the relationship between LS and OL.This study was conducted at Saudi banks in Al-Taif Governorate, Kingdom of Saudi Arabia. This research is practical, according to its purpose, and descriptive according to its data collection method. Three groups of employees at Saudi banks were reviewed. Of the 335 questionnaires that were distributed, 285 usable questionnaires were returned, a response rate of 85%. The finding reveals that there are differences among the three groups of employees regarding their evaluative attitudes towards LS and OL. Also, this study reveals that the aspects of LS have a significantly direct effect on OL.Accordingly, the study provides a set of recommendations that included the need for Transactional Leadership Styles (TALS in general, and Transformational Leadership Style (TFLS in particular, in order to achieve the best response to the needs and wishes of the workers at Saudi banks to increase their contribution to the achievement of OL on the one hand, and raise the level of their performance and enhance competitive advantage of these organizations on the other hand.

The aim of this study is to assess the clinical presentation of 23 patients with subacute thyroiditis (SAT) and the diagnostic value of radionuclear scan. This is a cohort study, which consists of 23 patients with a suspected diagnosis of subacute thyroiditis. The study was carried out in the Endocrinology Clinic, King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between July 2002 and July 2004. Medical charts including age, gender, clinical presentation, systemic symptoms and clinical examination of the thyroid gland were reviewed. Laboratory data included white blood count and its differential count, erythrocyte sedimentation rate (ESR), thyroid function test and thyroid antibodies. The radionuclear scan results were also noted. The mode of therapy provided to patients and the outcome of the treatment during a follow up period of 2 years was reported. Twenty-three adult patients with subacute thyroiditis (15 females and 8 males with a female to male ratio of 1.9:1) were reviewed over a 2-year period. The mean age was 35.8+9.2 years. Eighteen patients (78%) had an upper respiratory tract infection at the initial clinical presentation. Twenty patients (87%) visited an Ear, Nose and Throat specialist for sore throat and abnormal sensation in the throat at least 2 weeks before presentation to the endocrinologist. Two patients were admitted to a medical unit with a diagnosis of fever of unknown origin for 4 weeks. All patients had an elevated free thyrks. All patients had an elevated free thyroxine (35.7+19.8 pmol/L) and suppressed thyroid-stimulating hormone (TSH) (0.043+0.065IU). The radionuclear scan showed either no uptake at all in 12 patients or minimal uptake in 11 patients (0.32+0.55%). Eight patients (35%) received prednisolone therapy alone with an average dose of 30-40 mg daily for 7-8 days; 7 patients (30%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs) only. Eight (35%) patients were treated with both NSAIDs and corticosteroids. Hypothyroidism, with elevated TSH, was observed in 6 (26%) of our patients with positive thyroid antibodies during the first 6 months of follow up. There were no reported cases of recurrent or permanent hypothyroidism in our cohort study. Subacute thyroiditis is an uncommon disease that should be considered in the differential diagnosis of acute anterior neck pain, sore throat and fever especially in patients who do not respond to treatment. In the clinical setting, radioiodine uptake can help exclude other diseases, confirm the diagnosis and expedite the initiation of appropriate therapy to relieve symptoms. (author)
Globalisation is often thought to advocate for a single set of beliefs and customs and for a rejection of the need to protect regional cultures and traditions. In the aftermath of 9/11, the rift between Western and Arab cultures has deepened, and there is a patent need for cultural bridges to be built. The government of Saudi Arabia has, by increasing funding for higher education through grants and scholarships, enabled Saudi students to study at overseas universities. A number of non-Saudi students are also enrolled at Saudi Arabian universities. After a brief introduction to the cultural and educational history of the Arab region and Saudi identity, this article turns to contemporary higher education in Saudi Arabia. It introduces the King Abdullah Scholarship Programme and then goes on to present detailed enrolment data for 2006-2009, demonstrating trends and policy changes and identifying patterns in student mobility.

The paper recounts the history of Saudi Arabia's first national oil company, Petromin, which was originally supposed to take the place of foreign-owned Aramco. As a result of Petromin's inefficiency and personal rivalries among the Saudi elite, however, Petromin was progressively relegated to the sidelines in favour of a gradually 'Saudiised' Aramco. As a result, the organisation of the Saudi oil sector today is very different from - and more efficient than - that of most other oil exporters ...

Full Text Available As we know investment in the Saudi stock market (TASI is gaining popularity particularly since 2001 (Report of Aljazira Capital – 2010, it is important to know the impact of different macro-economic variables on the returns of the Saudi stock market. In this regard along with an extensive literature review we also referred specific recent few important studies which considered the Saudi stock return as a dependent variable and other economic factors as the independent variables [Kalyanaraman and Al-Tuwajri (2014, Arouri and Rault (2010 and Onour (2008]. This paper examines the three important factors influencing the returns in the Saudi Stock Exchange (TASI based on the macroeconomic variables of Saudi Economy. The dependent variable taken here is the Saudi index that is TADAWUL All Stock Index (TASI and the three independent variables considered for our study here are the Oil WTI, Saudi Exports and the PE Ratio. Correlation analysis revealed that Saudi Exports and the PE Ratio were found to be highly correlated with TASI at 1% level of significance whereas Oil WTI and TASI are significantly correlated at 5% level. Step-wise regression analysis of the data revealed that the multiple regression models is significant at 1% level and the variable PE Ratio was the most important determinant of TASI followed by Oil WTI and Saudi Exports. Further the three independent variables explain about 93% of variation in the TASI Last Price.

BACKGROUND AND OBJECTIVES: Few studies have been conducted in Saudi Arabia to estimate the prevalence of visual impairment and its causes. The objective of this study was to estimate the prevalence of visual impairment, and identify its causes and associated factors among the adult population attending primary health care (PHC) centers in Aljouf province, in northern Saudi Arabia. DESIGN AND SETTING: A cross-sectional study during the year 2005 in PHC centers in Aljouf province in northern Saudi Arabia PATIENTS AND METHODS: A sample of 620 Saudi adults, of age 18 years and older, from the catchment area of the Aljouf PHC centers, were randomly selected through a multistage random sampling technique. Data were collected using a questionnaire about socioeconomic and related information and a visual acuity test was performed using the Snellen chart (E). Diagnosis was established according to World Health Organization (WHO) criteria. Visual impairment was categorized into blindness for a visual acuity of less than 3/60 (20/400, 0.05) in the better eye with the best correction and low vision for a best corrected visual acuity of less than 6/18 (20/60, 0.3) but not less than 3/60 (20/400, 0.05) in the better eye. Regression analysis was used to identify the predictors of visual impairment. RESULTS: Of 617 adult Saudis interviewed and examined, 269 (43.6%) were females. The mean (SD) age was 38.6 (16.2) years. The overall prevalence of visual impairment was 13.9% (95% CI: 11.4%-16.9%). The main medical causes of visual impairments were refractive errors (36.0%) followed by cataract (29.1%) and diabetic retinopathy (20.9%), and the least leading cause was glaucoma (5.8%). The most prominent determinants of visual impairment were age (P<.05), sex (P<.001), and a history of previous eye injury (P<.05). CONCLUSION: Prevalence of visual impairment in the study population from the Aljouf area is high. It is recommended that regular checks of visual acuity be conducted for all Saudis of age 50+ years, who attend the PHC centers. PMID:21911984

Full Text Available Background: Pigmentary demarcation lines (PDL are physiological abrupt transition lines between hyperpigmented skin and lighter areas. Recent evidence suggests that they involve the face. Aims: To survey facial PDL in Saudi females referred to general dermatology clinics for various complaints and determine any associated risks. Methods: Screening for facial lines was done in general dermatology clinics over a year. Whenever a patient was found to have facial PDL, a detailed questionnaire and examination were undertaken. Results: Out of 1033 patients screened, 144 patients (14% were found to have at least one of the facial PDLs. The median age of onset was 16 years. The most common line was F with 76 patients (53%. Family history was positive in 51 patients (35%. Conclusion: Facial PDL is a common and chronic pigmentary problem in Saudi women. It should be recognized and differentiated from other similar diseases like melasma. A significant proportion of patients have a milder presentation.
Full Text Available Obesity is alarmingly raising in young people necessitating foridentification of precise causes specific for populations. The aim of the present study is to determine independent contribution of parental socioeconomic variables and self-life style factors to obesity in Saudi female college students. We performed a cross-sectional study using a random selection of 300 women aged 18–26 years recruited from the female campus of University of Hail, Saudi Arabia and collected self-reported information to meet study objectives. Around 32 % of females were either overweight or obese and the study subjects with a family history of maternal obesity and habit of limited snacking had higher odds for obesity. No associations were found between obesity and parental income and education status; and skipping breakfast and physical activity behaviours of the subjects. Maternal obesity could be a considerable risk factor for obesity in female subjects.

This paper reports on the prevalence of oral lichen planus among 4277 dental patients aged 18-73 years, seen in the Dental Department, King Fahad Central Hospital, Gizan, Saudi Arabia, between 1982 and 1987. Oral mucosal lesions, diagnosed as lichen planus, were clinically and histologically identified in 72 subjects (40 males and 32 females). The average age of the affected group was 49 years. No correlation was evident between lichen planus and tobacco habits in this study, nor was there any association with diabetes or hypertension. The average period of follow-up was 3.2 years, during which time 4 patients developed malignant transformation of their oral lesions. The prevalence of lichen planus in this study was 1.7%, which is higher than the prevalence figures reported earlier for this disease in Saudi Arabia. (author)
Eight species of the genus Cunnolites Barrére (1746) from the Maastrichtian of Central Saudi Arabia are described and illustrated in this paper. These consist of Cunnolites (Cunnolites) macrostoma (Reuss, 1854), C. (C.) tenuiradiata (Fromentel, 1870), C. (C.) elliptica (Lamarck, 1816), C. (Paracunnolites) orbignyi (Fromentel, 1864), C. (P.) undulata (Goldfuss, 1826) var. plana (Oppenheim, 1930), C. (P.) humilis (Quenstedt, 1880), C. (P.) minima (Fromentel, 1863) and C. (Plesiocunnolites) reussi (Fromentel, 1862). Species of the genus Cunnolites from Saudi Arabia are distinguished by their septa of different cycles being highly perforate at the lower, axial and upper parts of the corallum; their granules and pennulae on the lateral sides of septa are numerous but become fewer in the lower part of corallum and by some of their septa being anastomosed.

A survey was carried out on Saudi sheep and goats during 1995, at the Veterinary Diagnostic laboratory, Jeddah, to study Setaria infection in small ruminants in Saudi Arabia. Setaria digitata worms were detected in the abdominal cavity of 5 out of 48 goats (10.4%). Sheep were not found to be infected. All infected goats were adults of 2-4 years of age and originating from the Jeddah, Mecca and Al-Leith areas. Four cases were recorded during January-March and one during August. No lesions due to S. digitata were found in the visceral organs and brains of the infected goats. This is the first record of patent infection with S. digitata in goats. PMID:10321587

Full Text Available The present paper attempts to explore the characteristics of an effective teacher of English. Some related factors such as qualification, attributes, roles, and professional ethics have also been dealt with. In Saudi Arabia, the teacher of English plays the most important role in the process of teaching/learning. There are so many factors such as L1 interference, parental attitude, home environment, schooling etc that are usually influential in the case of educational setting in general and English classes in particular. It is believed that if the teacher of English has undergone a pre-service teacher training it is better for the learners of Saudi Arabia. In the other case, those who have not attended pre-service teacher training, they should go for in-service professional development programs in order to equip them further for innovative teaching and educational output.

The evolutionary conservation of a housekeeping gene such as G6PD is greater than that of tissue-specific genes, presumably because the latter may require more specific adaptation to the physiology of individual organisms. The abundance of distinct mutation sites and their clinical manifestations make G6PD ideal for structure-function analysis. Therefore, it is of interest to screen of G6PD deficiency in the blood donors in Kingdom of Saudi Arabia. We report the mean and variation of enzyme activity in a huge set of Suadi to non-Saudi population with reference to the entire population. The sequence level conservation of G6PD among distant species is demonstrated using phylogenetic trees. These observations have implications in the sequence-structure-function understanding of G6PD with reference to its association to several human diseases. PMID:23275731

Previous studies have reported different levels of perception of attractiveness among different ethnicities and among varying education-level groups on facial profile rating.To study the perception of facial profile attractiveness among Saudi dentists and lay-individuals. Digital facial profile images with altered degree of prognathism and retrognathism were presented to a sample of 60 Saudi dentists and 60 lay-persons with equal gender distribution. High reliability of repeated assessment of profile images was detected (ICC=0.982). Significant difference in perception of facial profile was found between genders (P<0.05) and among the groups with different education backgrounds (P<0.001). General agreement was established in both sample groups on average facial profile to be the most attractive and on the most retrognathic profile to be the least attractive. (author)

Full Text Available Little is known about the geographic distribution of common cancers in Saudi Arabia. We explored the spatial incidence patterns of common cancers in Saudi Arabia using spatial autocorrelation analyses, employing the global Moran’s I and Anselin’s local Moran’s I statistics to detect nonrandom incidence patterns. Global ordinary least squares (OLS regression and local geographically-weighted regression (GWR were applied to examine the spatial correlation of cancer incidences at the city level. Population-based records of cancers diagnosed between 1998 and 2004 were used. Male lung cancer and female breast cancer exhibited positive statistically significant global Moran’s I index values, indicating a tendency toward clustering. The Anselin’s local Moran’s I analyses revealed small significant clusters of lung cancer, prostate cancer and Hodgkin’s disease among males in the Eastern region and significant clusters of thyroid cancers in females in the Eastern and Riyadh regions. Additionally, both regression methods found significant associations among various cancers. For example, OLS and GWR revealed significant spatial associations among NHL, leukemia and Hodgkin’s disease (r² = 0.49–0.67 using OLS and r² = 0.52–0.68 using GWR and between breast and prostate cancer (r² = 0.53 OLS and 0.57 GWR in Saudi Arabian cities. These findings may help to generate etiologic hypotheses of cancer causation and identify spatial anomalies in cancer incidence in Saudi Arabia. Our findings should stimulate further research on the possible causes underlying these clusters and associations.

The clinical features of this syndrome include renal involvement, ocular involve-ment, retinitis pigmentosa and other systemic involvement. We describe an 11-year-old Saudi girl who was diagnosed to have this syndrome. To the best of our knowledge, this is the first report of this syndrome from the Arabian Peninsula.
Mesenteric ischemia is relatively a rare disorder seen in the emergency department (ED). Due to the effect of hypobaric hypoxia and higher liability for thrombosis encountered in high altitude areas, acute occlusive mesenteric ischemia (AOMI) would represent an actual challenge in Taif and related districts. Another risk factor is that about twenty-five percent of Saudis are victims of diabetes due to the changes in lifestyle and diet leading to increasing levels of obesity. Vague nonspecific...

The practice of pharmacy, as well as pharmacy education, varies significantly throughout the world. In Jordan, Kuwait, and Saudi Arabia, the profession of pharmacy appears to be on the ascendance. This is demonstrated by an increase in the number of pharmacy schools and the number of pharmacy graduates from pharmacy programs. One of the reasons pharmacy is on the ascendance in these countries is government commitment to fund and support competitive, well-run pharmacy programs.

Little attention has been paid to the problem of male osteoporosis in Saudi Arabia. In this prospective study we assessed the prevalence of male osteoporosis among Saudi Arabs. We studied Saudi Arabian males > 50 years of age attending outpatient clinics at King Fahd Hospital of the University, Al-Khobar, between 1st May 2005 and 30th January 2006. We determined body mass index (BMI) and tests were done to rule out secondary osteoporosis. All subjects had a bone mineral density (BMD) measurement of the hip area and the lumbar spine using dual energy x-ray absorptiometry (DEXA). A T-score of<=-2.5 SD that of young, healthy adults was taken as osteoporotic and scores between -1 to -2.5SD were taken as osteopenic. One hundred fifteen patients (mean age 61.8+-0.75 years; range 50 to 76 years) had a mean BMI of 24.7+-0.35 (range 18.5 to 31). Based on hip scans, the prevalence of osteoporosis was 24.3%. Sixty four percent were osteopenic. Based on scans of lumbar spine, the prevalence of osteoporosis was 37.4% and 33.9% were osteopenic. Spinal osteoporosis was more common than hip osteoporosis. Our study indicates that the prevalence of osteopoprosis among Saudi Arabain males is higher than among Western males. More studies are needed to determine the national prevalence of male osteoporosis. It is recommended that serious measures to be undertaken to prevent male osteoporosis to stop any future epidemic of catastrophic osteoporosis-related fractures. (author)-related fractures. (author)

Introduction Data on obesity from the Kingdom of Saudi Arabia (KSA) are nonexistent, making it impossible to determine whether the efforts of the Saudi Ministry of Health are having an effect on obesity trends. To determine obesity prevalence and associated factors in the KSA, we conducted a national survey on chronic diseases and their risk factors. Methods We interviewed 10,735 Saudis aged 15 years or older (51.1% women) through a multistage survey. Data on sociodemographic characteristics, health-related habits and behaviors, diet, physical activity, chronic diseases, access to and use of health care, and anthropometric measurements were collected through computer-assisted personal interviews. We first compared sociodemographic factors and body mass index between men and women. Next, we conducted a sex-specific analysis for obesity and its associated factors using backward elimination multivariate logistic regression models. We used SAS 9.3 for the statistical analyses and to account for the complex sampling design. Results Of the 10,735 participants evaluated, 28.7% were obese (body mass index ?30 kg/m2). Prevalence of obesity was higher among women (33.5% vs 24.1%). Among men, obesity was associated with marital status, diet, physical activity, diagnoses of diabetes and hypercholesterolemia, and hypertension. Among women, obesity was associated with marital status, education, history of chronic conditions, and hypertension. Conclusion Obesity remains strongly associated with diabetes, hypercholesterolemia, and hypertension in the KSA, although the epidemic’s characteristics differ between men and women. PMID:25299980

Measurement of indoor radon concentration was performed in Najran region in the south west of Saudi Arabia, using CR-39 dosimeter. Despite many previous studies on indoor radon concentrations in Saudi Arabia, the data available are still limited. The objective of this study, which is the first of its kind in the region, is to have preliminary data of radon in this region. Such measurement will contribute towards further studies in this region of Saudi Arabia. The indoor radon concentration was measured in the villages of Fara Al-Jabal and Badr Al-Janoob (about 2000 m above sea level), Hadadah and Al-Khanig (about 1700 m above sea level). It was found that radon distribution in these villages is normal skewed to the right, with a range of 9±5 to 163±32 Bqm-3 and an average of 49±2 Bqm-3. It was also found that the average radon concentration is independent of altitude. Our findings show that the values are below the safe limit of 150 Bqm-3 set by the Environmental Protection Agency (EPA) of the USA

The purpose of this exploratory study is to provide an overview of a web-based health educational site created by the King Faisal Specialist Hospital and Research Center (KFSH&RC) in the Kingdom of Saudi Arabia (KSA). Sources of data included two interviews with Saudi IT personnel, three health educators, and two medical consultants working at KFSH&RC. The interviews ranged between 45 minutes and 120 minutes. The KFSH&RC website was also searched for the type of health information content posted. Results show that the KFSH&RC web-based health educational site provides health information through a medical encyclopedia, a social networking platform, health educational links, and targeted health information for children, which includes tools such as games and coloring books. Further research is needed on the effectiveness of the KFSH&RC web-based health education site in terms of improving knowledge and changing behavior of Saudi patients. The study recommends that targeted web-based health education strategies should be developed to reach large rural populations which have inadequate computer skills and limited access to the internet.

This study attempts to explain why crude oil prices fluctuate, the main cause being the quota regime, which characterises the OPEC agreements. Given that the Saudi oil supply is inelastic in the short term, a shock in the oil market is accommodated by an immediate price change. By contrast, a dominant firm behaviour in the long term causes an output change, which is accompanied by a smaller price change. This explains why oil prices overshoot. The results of a general equilibrium model applied to Saudi Arabia support this analysis. They also indicate that Saudi Arabia does not have any incentive for altering the crude oil market equilibrium with either positive or negative supply shocks, as its welfare declines; and that it has an incentive (disincentive) for intervening if a negative (positive) demand shock hits the crude oil market. A second set of simulations is designed to understand what kind of OECD policy might help to bring down prices. A tax cut would worsen the situation, whereas policies that can increase the price elasticity of demand seem to be very effective. (Author)
Full Text Available Objectives: To assess the prevalence of epidemiologically defined chronic obstructive pulmonary disease (COPD in Saudi Arabia. Methods: This cross-sectional, observational, population-based survey of COPD was conducted between June 2010 and December 2011 across the country of Saudi Arabia.

Objective was to analyze the results of exercise tolerance test ETT of Saudi women and assess their exercise capacity. A hospital based retrospective cohort analysis was carried out on all Saudi women referred to the Cardiology Department for ETT from February 2005 to June 2007. They underwent symptom limited treadmill test according to the standard Bruce protocol with exercise electrocardiogram monitoring. One hundred and seventy-six women were included in the study. Fifty-one 31.9% patients did not achieve target heart rate. The mean age +/- SD was 48.3+-9.3 years. There was no association of age, diabetes mellitus, hypertension, positive family history of ischemic heart disease IHD and hyperlipidemia to achieve target heart rate p>0.05. Exercise time was influenced by diabetes mellitus p=0.054 and hyperlipidemia p=0.044. The mean exercise time +/- SD was 5.15+/-2.63 minutes and the mean exercise capacity +/-SD was 6.29+/-2.52 metabolic equivalent. Sensitivity was 36.4%, 95% CI 29.3-44.6, specificity 92.3%, 95% CI 80.5-96.8, positive predictive value 26.7%, 95% CI 21.3-31.4, negative predictive value 95.4%, 95% CI 90.9-98.3, likelihood ratio for positive result was 4.7, 95%CI 3.1-6.2 and likelihood ratio for negative result was 0.69, 95% CI 0.48-0.81. Exercise capacity of Saudi women is less compared to similar studies in women from other regions. Exercise tolerance test can be used to rule out presence of IHD in Saudi women, but value of a positive test is less lik, but value of a positive test is less likely to predict the presence of IHD.

All primigravid Saudi women ?24 weeks gestation, carrying a singleton pregnancy, aged <35 years, and with no chronic medical problems were eligible. Women were divided into three groups based on their age, ie, group 1 (G1 <16 years, group 2 (G2 ?16 up to 19 years, and group 3 (G3 ?19 up to 35 years. Data were collected from maternal and neonatal medical records. We calculated the association between the different age groups and maternal characteristics, as well as events and complications during the antenatal period, labor, and delivery.Results: The rates of adolescent delivery were 20.0 and 16.3 per 1,000 births in 2009 and 2010, respectively. Compared with G1 and G2 women, G3 women tended to have a higher body mass index, a longer first and second stage of labor, more blood loss at delivery, and a longer hospital stay. Compared with G1 and G2 women, respectively, G3 women had a 42% and a 67% increased risk of cesarean section, and had a 52% increased risk of instrumental delivery. G3 women were more likely to develop gestational diabetes or anemia, G2 women had a three-fold increased risk of premature delivery (odds ratio 2.81, and G3 neonates had a 50% increased overall risk of neonatal complications (odds ratio 0.51.Conclusion: The adolescent birth rate appears to be low in central Saudi Arabia compared with other parts of the world. Excluding preterm delivery, adolescent delivery cared for in a tertiary health care center is not associated with a significantly increased medical risk to the mother, fetus, or neonate. The psychosocial effect of adolescent pregnancy and delivery needs to be assessed.Keywords: adolescent pregnancy, maternal mortality, maternal morbidity, neonatal mortality, neonatal morbidity
Full Text Available Background and Objectives: No previous study has provided a detailed description of regional variations of growth within the various regions of Saudi Arabia. Thus, we sought to demonstrate differences in growth of children and adolescents in different regions. Subjects and Methods: The 2005 Saudi reference was based on a cross-sectional representative sample of the Saudi population of healthy children and adolescents from birth to 18 years of age. Body measurements of the length, stature, weight, head circumference and calculation of the BMI were performed according to standard recommendations. Percentile construction and smoothing were performed using the LMS (lambda, mu and sigma methodology, followed by transformation of all individual measurements into standard deviation scores. Factors such as weight for age, height for age, weight for height, and head circumference for children from birth to 3 years, stature for age, head circumference and body mass index for children between 2-18 years of age were assessed. Subsequently, variations in growth between the three main regions in the north, southwest, and center of Saudi Arabia were calculated, with the Bonferroni: method used to assess the significance of differences between regions. Results: There were significant differences in growth between regions that varied according to age, gender, growth parameter and region. The highest variation was found between children and adolescents of the southwestern region and those of the other two regions The regression lines for all growth parameters in children < 3 years of age were significantly different from one region to another reaching - 0.65 standard deviation scores for the southwestern regions ( P =.001. However, the difference between the northern and central regions were not significant for the head circumference and for weight for length. For older children and adolescents a significant difference was found in all parameters except between the northern and central regions in BMI in girls and head circumference in boys. Finally, the difference in head circumference of girls between southwestern and northern regions was not significant. Such variation affected all growth parameters for both boys and girls. Conclusion: Regional variations in growth need to be taken into consideration when assessing the growth of Saudi children and adolescents.

Full Text Available The aim of this study was to investigate intake of macronutrients and its relation to Body Mass Index (BMI as well as intake of selected micronutrients in urban and rural healthy adults in Riyadh region-Saudi Arabia. 170 health adults were recruited, 85 of which were urbans and 85 were rurals. Three consecutive days food records were collected and dietary intakes were analyzed by the food processor and other food composition tables. Results showed high intake of macronutrients and prevalence of overweight and obesity in both groups with no significant differences. Subjects of both groups also had high intake of saturated fat. Results also showed inadequate intake of vitamin D, calcium and folate. Few of the participants of both groups had inadequate intake of vitamin C. Intakes of vitamin B1, vitamin B3, iron, vitamin B12, vitamin B6 and vitamin B2 was adequate. No significant differences between the two groups were observed except for vitamin D, calcium and vitamin B2 that their mean intakes were significantly higher in urban group compared to rural group. Mean intake of vitamin B3 was higher in rural group compared to urban group. These findings suggested that overweight and obesity among adult Saudis are due to high intake of macronutrients combined with inadequate intake of some micronutrients, which are results of non-balanced diet and inappropriate consumption patterns. The study also suggests that there is a need of increasing the nutritional education and awareness among adult Saudi males.

Europe and Asia except, all the differentials of prices have readjusted in fall in the month of april. For United States, the fall of differentials have been varied between $0.05/b and $0.15/b according to the qualities. For Europe, similar falls have been decided for crude and middle oils and are following the strong increases of february, provoked by the cold spell of the two first months of the year. In an other point of view, the production and the benefits of the Saudi Basic Industries Corporation (Sabic) reach record levels of 22 Mt and $1.67 milliards in 1995. The Saudi Petrochemical Company (Sadaf), joint venture between Sabic and Pecten Saudi Arabia, affiliate of American Shell Oil, will begin next july the production, in experimental phase of its new unit of 700 000 t/year of MTBE/ETBE (methyl or ethyl-tertio-butyl-ether). It will be the first worldwide factory of this capacity to produce MTBE/ETBE. The National Plastic Company (Ibn Hayyan) has created a new affiliate Ibn Hayyan Plastic Products Company to build a new factory in its complex of Joubail, which will produce 40 000 t/year of plastic products. Finally, the construction at Joubail of the 50 000 t/year of caustic soda factory, the Arabian Industrial Development Company (Nama) will be achieved in january 1997 and the production start is planned two months later.

This study presents the findings of the first population-based tumor registry in the Eastern region (ER). Data on all cancer sites, in 1987 and 1988, were captured from all health facilities in the ER. A regional population census was obtained from regional health authorities. Cancer deaths were obtained from death registries. Age-specific rate, crude incidence rate (CIR), age-standardized incidence rate (ASR) and relative age-standardized incidence rate (%ASR) were compared with available population-based data from 137 tumor registries. 1559 primary cancer cases were captured. The CIR and ASR/100,000/year for cancer among Saudi males were respectively 59.8 and 125.7. The corresponding rates among Saudi females were 43.6 and 95.5. These rates rank very low on the international scale. Cancer sites with the highest %ASR among Saudi males were lung, lymphomas, leukemias, urinary bladder and tumors of uncertain primary. For Saudi females, these sites were breast, leukemias, tumors of brain and nervous system, thyroid and tumors of uncertain primary. Lung cancer was the leading cause of death from cancer among Saudi males. The first regional population-based cancer registry in Saudi Arabia was established in 1987. The overall cancer ASR in the ER is low. The leading cancer sites with the highest %ASR are lung in Saudi males and breast in Saudi females. PMID:17372393

Greater knowledge of the factors affecting fertility may help to decrease the incidence of infertility by allowing couples to avoid certain risk factors. The aim of our study was (1 to assess the knowledge and attitudes of infertile and fertile Saudi participants on infertility, possible risk factors, and social consequences; and (2 to determine the practices of infertile Saudi couples to promote their fertility before having them attend an in vitro fertilization (IVF clinic. Methods and materials: We conducted a cross-sectional study on 277 fertile participants from outpatient clinics and 104 infertile patients from the IVF clinic at King Abdulaziz Medical City between June 24, 2012 and July 4, 2012, using a previously validated interview questionnaire. Descriptive and analytical statistics were applied with a significance threshold of P ? 0.05. Results: A generally poor level of knowledge (59% and a neutral attitude (76% toward infertility were reported by participants. Mistaken beliefs commonly held by the study participants regarding the causes of infertility were Djinns and supernatural causes (58.8%, black magic (67.5%, intrauterine devices (71.3%, and contraceptive pills (42.9%. The healer/Sheikh was reported as the primary and secondary preference for infertility treatment by 6.7% and 44.2% of IVF patients, respectively. Compared with fertile patients, IVF patients were significantly less likely to favor divorce (38.5% versus 57.6%; P = 0.001 or marriage to a second wife (62.5% versus 86.2%; P < 0.001, if the woman could not have a baby. The patients with infertility had more favorable attitudes toward fertility drugs (87.5% versus 68.4%; P = 0.003 and having a test tube baby (92.4% versus 70.3%; P < 0.001. Child adoption was accepted as an option for treatment by the majority of IVF patients (60.6% and fertile outpatients (71.5%. Alternative treatments previously practiced by the IVF patients to improve fertility include practicing Ruqia (61%, using alternative medicine (42%, engaging in physical exercise (39%, eating certain foods (22%, and quitting smoking (12%. Conclusion: These findings have implications for health care providers regarding the reluctance that couples experiencing fertility problems may have, at least initially, to accept some interventions required for the couple to conceive.

Full Text Available This study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure gender differences with regard to continuance online shopping intentions in Saudi Arabia. The sample consists of 650 female respondents. A structural equation model confirms model fit. Perceived enjoyment, usefulness, and subjective norms are determinants of online shopping continuance in Saudi Arabia. High and low online spenders among women in Saudi Arabia are equivalent. The structural weights are also largely equivalent, but the regression paths from perceived site quality to perceived usefulness is not invariant between high and low e-shoppers in Saudi Arabia. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The research model explains 60% of the female respondentsâ€™ intention to continue shopping online. Online strategies cannot ignore either the direct and indirect spending differences on continuance intentions, and the model can be generalized across Saudi Arabia.

Full Text Available Influenced by the success of shale gas production worldwide and to meet requirements for clean energy supply, a multidisciplinary team of petroleum specialists was established in Saudi Aramco. Meeting the growing requirement in industrial consumption and especially electricity production is a driving force for developing unconventional gas reserves. ``The initial focus is in the northwest and in the area of Ghawar, where gas infrastructure exists. The company is innovatively combining knowledge and research to maximize gas reserves and production from conventional and unconventional resources in order to meet growing domestic demand (Saudi Aramco. 2010.During years 2010 - 2011 major international petroleum industry players - Schlumberger, Halliburton and Baker Hughes - were invited to share their experience in a series of workshops held in Dhahran. Exchange of expert ideas developed into appreciation of complexity of the shale gas reservoir and helped to identify the scope of work for the first Silurian Qusaiba shale gas well. The SHALE-1 well was drilled in 2007 as a gas exploration well. Recent drilling and geophysical data obtained in the well were beneficial for detailed sidetrack and fracture stimulation design.The Multidisciplinary task group was established and positioned in Dhahran. The draft work plan was developed 8 months before actual operations commenced on the well site. Thorough examination of the draft work plan progressed to the final work plan with a number of improvements. The Frac Stimulation design was fine-tuned, involving expertise from Saudi Aramco and Halliburton. The Complete Well on Paper exercise involved over 25 specialists from both companies and helped to rectify remaining completion/stimulation design issues, and put everyone on the same page in terms of the work program. Well site operations commenced in May 2011. All targets set for the SHALE-1 well were successfully achieved and the well was suspended for future utilization as an observation well.
Ash Shuqayq (Saudi Red Sea coast) is approximately 28 km long and characterised by narrow rocky headlands with intermittent pocket beaches. Fifty-two sediment samples from six different environments (beach, dune, sabkha, tidal/lagoon, offshore and wadi) were analysed. Testing showed that beach and dune sands are mainly medium to fine grained, with some very coarse sand (MZ = ? 0.59ø). Both beach and dune sands are moderately well to moderately sorted, although some are poorly sorted due to an influx of wadi sediments. Sediment source together with littoral reworking contributed to grain size variation. Carbonate content varied between 1.5% and 23%, whilst the organic content varied between 1.1% and 13%. Spatial analysis showed increasing southward carbonate and organic content, with both correlated (r = 0.57). Sabkha sediments had significantly higher carbonate percentages (t = 2.898; df = 18; p < 0.01) and results suggested origins are similar for both UAE Arabian Sea and Saudi Arabian Red Sea coasts. X-ray diffractions show beach and dune sediments are mainly composed of detrital quartz and plagioclase feldspar with uncommon amounts of chlorites. Analysis of sediment characteristics, composition and shoreline distribution alongside coastal processes, indicate that high chlorite levels are probably caused by desalination processes. Due to human and ecosystem health consequences and the likely increased demand for desalination plants, similar analyses should be und plants, similar analyses should be undertaken elsewhere, e.g. the Mediterranean. - Highlights: ? New and previously unpublished Red Sea sediment information. ? Sediment chemical and spatial variations established. ? Sabkha origins are similar for both UAE Arabian Sea and Saudi Arabian Red Sea coasts. ? Desalination plant shown as cause of increased marine sediment chlorite levels.
Full Text Available Aim: To review a general hospital?s experience with sarcoidosis and the clinical pattern of the disease among Saudis. Methods: A retrospective file review was carried out on all patients with a proven diagnosis of sarcoidosis in a general hospital in Eastern Saudi Arabia over a period of 11 years (1998-2008. Results: Sixty-nine patients, of whom 33 cases were included in the analyses, were diagnosed to have sarcoidosis during the study period. There were 18 females and 15 males. The mean age was 44.5 years (SD 17. The most common presentations were cough (48%, dyspnea (21%, joint pain (18%, splenomegaly (12%, hepatomegaly (9%, and lymphadenopathy (5%. The biochemical analysis showed elevated calcium levels in 6% and elevated angiotensin converting enzyme (ACE in 14 (46.7%. The tuberculin skin test was negative in all tested patients (n = 29 except one patient. The patients were classified using the modified Scadding classification system. None of the patients was in stage 0, 39.4% were in stage 1, 45% were in stage 2 and 15% were in stage 3.. The diagnosis in all patients was proven histologically. The outcome was favorable in most patients (85%, and in 6% of the patients, the course was chronic and progressive, although 66% received active treatment. Conclusion: Sarcoidosis does occur in native Saudis. The clinical presentation of these patients was similar to the western pattern of disease with some differences such as relative lack of cardiac, eye, parotid, and central nervous system involvement. The rarity of cardiac and central nervous system involvement was comparable with other Middle Eastern studies. Sarcoidosis, though rare in our community, should still be considered in the differential diagnosis of patients with the typical presentation after excluding tuberculosis.
Congenital anomalies contribute a significant proportion of infant morbidity and mortality, as well as fetal mortality. They are generally grouped into three major categories: structural/metabolic, congenital infections, and other conditions. The most prevalent conditions include congenital heart defects, orofacial clefts, Down syndrome, and neural tube defects. Several prenatal diagnostic procedures have been introduced, both cytogenetic (such as chorion biopsy, amniocentesis and funiculocentesis) and biophysical (ultrasound 2-D, 3-D and 4-D, ultrasonography with Doppler, etc.). Insufficient data are currently available from Saudi Arabia on the epidemiology of the lethal congenital abnormalities which should be a priority due to high rate of consanguineous marriages among first cousins and their association with congenital anomalies. In terms of consanguinity and birth defects, a significant positive association has been consistently demonstrated between consanguinity and morbidity, and congenital defects with a complex etiology appear to be both more prevalent in consanguineous families and have a greater likelihood of recurrence. A debate regarding aborting a malformed fetus still exists among the senior Islamic scholars in many of the Islamic countries. The progressive interpretations of Islam have resulted in laws allowing for early abortion on request in two countries; six others permit abortion on health grounds and three more also allow abortion in cases of rape or fetal impairment. In Saudi Arabia, efforts to legalize abortion in certain circumstances have been recently discussed among Senior Religious Scholars and specialized physicians to permit abortions in certain circumstances. In this mini-review we discuss the current debate regarding aborting a malformed fetus in Saudi Arabia with a focus on the Islamic perspective. PMID:24027674

Full Text Available Several studies have indicated a lack of nutritional knowledge among physicians. As there is no published data in nutritional knowledge among physicians in Saudi Arabia, hence the purpose of this current study was to assess the nutrition knowledge of primary care physicians working in Riyadh, Saudi Arabia. Nutrition knowledge questionnaire consisted of 16 multiple-choice questions, was mailed to 105 primary care physicians working in Riyadh, Saudi Arabia. The questionnaire was pre- tested in a pilot study. Non-respondents received a second questionnaire and a phone call. Of the 105 primary care physicians, 59 replies were received (56.2%. The mean mark for correctly answered questions was 51.7%. Approximately 75 % of the physicians described their knowledge of nutrition as `Poor`. The results indicate that physicians are generally aware of information which has been publicized in the medical press: nutrient which helps prevent thrombosis (omega-3 fat; the preventive action of fruit and vegetables against cancer; which nutrients are antioxidants; the nutrient associated with the prevention of neural tube defects (folate. By contrast they have a poor knowledge of other important topics in nutrition: the major type of fat in olive oil; hydrogenated fats; source of vitamin B12; Substance raises the blood HDL-cholesterol level (Alcohol; the association between excess protein intake and calcium loss; the type of dietary fiber helpful in lowering the blood cholesterol level (soluble fiber and Nutrient is protective against hypertension. These results support other data that physicians need more education in nutrition. Nutrition should be an essential part in continuing medical education.

METHODS: Between December 2007 and January 2008, healthy students from the 10th to 12th grades were randomly selected from three regions in Saudi Arabia. These regions included the following: (1 Aseer region, with a student population of 25512; (2 Madinah, with a student population of 23852; and (3 Al-Qaseem, with a student population of 16067. Demographic data were recorded, and a venous blood sample (5-10 mL was taken from each student. The blood samples were tested for immunoglobulin A and immunoglobulin G endomysial antibodies (EMA by indirect immunofluorescence. RESULTS: In total, 1167 students (614 males and 553 females from these three regions were randomly selected. The majority of the study population was classified as lower middle class (82.7%. There were 26 (2.2% students who had a positive anti-EMA test, including 17 females (3.1% and 9 males (1.5%. Al-Qaseem region had the highest celiac disease prevalence among the three studied regions in Saudi Arabia (3.1%. The prevalence by region was as follows: Aseer 2.1% (10/479, Madinah 1.8% (8/436, and Al-Qaseem 3.2% (8/252. The prevalence in Madinah was significantly lower than the prevalence in Aseer and Al-Qaseem (P = 0.02. CONCLUSION: Our data suggest celiac disease prevalence might be one of the highest in the world. Further studies are needed to determine the real prevalence.

The aim of this study was to correlate the risk of PPD with obstetric and demographic variables in Saudi females. Materials and methods: Data were collected by interviewing females 8–12 weeks postpartum. PPD symptoms were defined as present when subjects had an Edinburgh Postnatal Depression Scale score of 10 or higher. Variables included in this study were age, education, occupation, parity, baby's sex, pregnancy period, delivery type, hemoglobin level, anemia, and iron pills taken during pregnancy. Results: Of the 352 postpartum females, the prevalence of PPD symptom risk was 117 (33.2%. Among the PPD symptomatic females, 66 (39.8% had low hemoglobin levels, and 45 (40.5% females were anemic during pregnancy (P?0.05. These results suggest that early postpartum anemia, indicated by low hemoglobin level, is a significant risk factor for PPD (adjusted odds ratio 1.70, 95% confidence interval 1.05–2.74; P=0.03. Other variables, including age, parity, education, occupation, and delivery type, were not significantly correlated (P=0.15–0.95, but marginally indicative of the risk of depressive symptoms. Conclusion: Low hemoglobin level and anemia during pregnancy were risk factors for PPD in Saudi females. Many other factors may be considered risk factors, such as age, occupation, and parity. Anemic women need more attention and to be checked regarding their PPD, and treated if necessary. Keywords: postpartum depression, hemoglobin level, anemia, EPDS
Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance in Saudi Arabia, consanguinity of parents is common and consequently the occurrence of family disease, including that of the skin, is not uncommon. To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical photographs of patients with recurring blistering diseases and conducted a histopathologic evaluation of skin biopsies to identify the site of cleavage. Eleven persons with PSS were seen at King Khalid National Guard Hospital in Jeddah between the years 1986 and 2005. Ages ranged between 2 and 15 years and there were 9 males (81.8%) and 2 females (18.2%). The most common presentation in the majority of patients was localized spontaneous peeling of the skin. Eight patients (72.8%) had a history of vesicles that were small, dry and peeled away. Trauma did no play role in blister formation. All patients were local from Bedouin tribes where a family history of a similar complaint was documented in 8 cases (72.7%). And consanguinity of marriage was evident on 6 patients (54.5%). Histological examination of the biopsies showed either intracorneal or superficial subcorneal cleavage above the granuler layer in all biopsied patients. Although rare, PSS occurs in Saudi Arabia and is most likely related to consanguinity of marriages. This disease is generally mild and is characterized by intrascorneal cleavage withinacterized by intrascorneal cleavage within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease. (author)
Objective was to explore the hematologic risk factors for stroke in cohort of Saudi children. We evaluated children at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Investigations for suspected cases included neuroimaging, transcranial Dopppler (TCD) for cases of sickle cell diseases (SCD), and Duplex scan. Hemostatic assays included coagulation screening tests, tests of thrombin generation and fibrinolysis, coagulation inhibitors, and activated protein C resistance. During the study period, 104 Saudi children (aged one month to 12 years) with stroke were seen. The mean age of the cohort was 27.1 months (SD=39.3 months) and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). A major risk factor was identified in 93 of 104 cases of stroke (89.4%). Hematologic disorders were the most common (46.2%), followed by prothrombic disorders (31.7%); microcystic hypochromic anemia (26%); sickle cell disease (SCD), or SCB-thalassemia, (11.5%), and factor IX deficiency (2.9%). Raised anticardiolipin antibodies (13/49, 26.5%) was the most frequent abnormality. Deficiencies of the natural anticoagulants (protein S, protein C and antithrombin III) were as follows: protein S (15/70, 21.4%); protein C (15/70,21.4%) and combined deficiency of 2 or more inhibitors mbined deficiency of 2 or more inhibitors (9/70, 12.9%). Activated protein C resistance has not been detected. Contrary to the findings of previous studies from Saudi Arabia, SCD is a common risk factor and is severe, as it resulted in multiple strokes. Moyamoya syndrome was diagnosed in 2 patients with SCD, one of whom had revascularization surgery (encephaldoduroarteriosynangiosis). Assessment of children with SCD at a risk of stroke was helped by the introduction of TCD followed by neuroimaging, using MRI and magnetic resonanceangiography. The study strongly highlights the importance of prothrombotic disorders and the severe phenotype of SCD as risk factors for stroke in Saudi children. (author)
Full Text Available One of the major world wide concerns of the utilities is to reduce the emissions from traditional power plants by using renewable energy and to reduce the high cost of supplying electricity to remote areas. Hybrid power systems can provide a good solution for such problems because they integrate renewable energy along with the traditional power plants. In Kingdom of Saudi Arabia a remote village called Al-Qtqt, was selected as a case study in order to investigate the ability to use a hybrid power system to provide the village with its needs of electricity. The simulation of this hybrid power system was done using HOMER software.
This study investigates the problems of EFL/ESL university students’ unwillingness to speak and take part in class discussions. Saudi students find it inappropriate to speak in class because of their fear to be seen as verbally challenging their teachers' views openly and publicly. Even when they do, they speak a little. This leads to frustration on the side of the teacher, in addition to the absence of any clear feedback from the students: whether they have/have not understood the lect...
"This article is intended to make a first assessment of the consequences of Indonesian immigration in Saudi Arabia, in particular during the first half of the 20th century, and to describe the evolution over time of certain striking aspects of the close relation between the pilgrimage to Mecca and Indonesian migrants looking for work.... This paper considers the methods of hiring labour, the networks involved in recruiting it, the organization of travel, as well as the increasing indebtedness of the migrants through intermediaries who, more and more professionally, arrange these attempts to live abroad...."

Full Text Available Academic research represents the backbone of human activity in the way that it improves our quality of life through expanding frontiers of academic knowledge and making further research possible throughout the world. Academic research aims to provide solutions for many current problems. The importance of academic research has grown at universities and research centres in Saudi Arabia, fuelled by dramatic increases in governmental and private funding for research. This study focuses on the academic publication processes in Saudi Arabia, the barriers that affect researchers’ ability to carry out and publish research and the potential advantages and disadvantages offered by the Internet in the area of academic publishing. The data collection and analysis presented in this study addresses the extent to which such benefit could be realised in practice. This research reviews the limitations of research publishing in Saudi Arabia by focusing on the nature of academic journals, in terms of their numbers and purpose, the barriers that academic staff faced when they wished to publish their research work in local or international academic journals, and the attitudes of academics towards electronic publishing and publishing in general. This research uses questionnaire tool. The data are tabulated and analysed in a systematic method to show findings in accordance with required objectives. The most prominent findings from this study are the lack of academic staff encouragement to conduct and publish research, lack of financial support to the research publishing sector, lack of a research publishing infrastructure and a lack of private sector support for funding research and publishing. An interesting finding is that unlike many other countries, there is no culture of volunteering for work that does not provide direct financial benefit. This could be an important factor affecting the adoption of an online open publishing approach in which reviewers and editors are not paid directly for the work. This research ultimately aims at proposing and implementing suitable processes and policies to solve these problems and to identifying means of overcoming the research publishing barriers in Saudi Arabia.

This study seeks to explain why crude oil prices fluctuate, the main cause being the quota regime, which characterises the OPEC agreements. Given that the Saudi oil supply is inelastic in the short term, a shock in the oil market is accommodated by an immediate price change. In contrast, a dominant firm behaviour in the long term causes an output change, which is accompanied by a smaller price change. This explains why oil prices overshoot. The results of a general equilibrium model applied t...

The purpose of this paper is to test the impact of oil price shocks on the stock markets of the two biggest and most liquid GCC equity markets, those of Kuwait and Saudi Arabia. It is expected that the two stock markets react similarly to oil price shocks. Actually the results show heterogeneity in responses. While there is prima facie evidence that both stock markets are influenced positively and linearly by oil price shocks, this evidence disappears when additional variables are added to th...

Wheat is one of the most grown crops in most of the world countries. Radionuclides may be concentrated in environment in a manner that can pose risk to human health. Accurate knowledge of such radionuclides in human food is of great importance to avoid any risk. In this work, Inductively coupled plasma mass spectrometry (ICP-MS) and ? -spectrometry techniques were applied to determination of uranium in wheat samples. Wheat samples were collected from ten regions through Saudi Arabia. Also bran and white flour samples were investigated. (author)

Descriptive statistics were used to report the results.Results: The responses indicated inadequate health-related practices in the surveyed group: 22.2% brushed their teeth twice daily, 73.6% never flossed their teeth, and while 80.2% visited a physician in the past year, only 12.6% visited a dentist during the same year. Of the respondents, 94.8% reported that they had never received advice on oral hygiene tasks in relation to diabetes from a health professional. Awareness about the diabetes and periodontal disease association was limited: 46.7% knew that diabetics have gum problems more often if their blood sugar stays very high, and only 21.8% knew that gum disease makes it harder to control blood sugar in diabetic patients. A significant association (P<0.05 was found between a higher level of education and greater general and oral awareness, as well as a significant association (P<0.05 between longer duration of disease, regular exercise, and regular visits to the physician and awareness about diabetes mellitus. Additionally, a significant association (P<0.05 was found between regular dental visits and both periodontal disease and diabetes awareness. Family and friends were the main source of diabetes-related information, and the Internet was the least likely source.Conclusion: Customized educational programs should be planned for diabetic patients according to community needs.Keywords: periodontal health, diabetes, patients, awareness, Saudi Arabia
The effect of energy conservation measures for a typical two-storey residential building in Saudi Arabia are studied. The analysis shows that insulating the walls and the roof (15 mm-thick insulation) results in a significant reduction in the peak cooling load (> 23%) and the annual energy consumption (> 27%). Hence, a significant saving in customer and government equivalent uniform annual cost (EUAC) will be observed. The effects of additional measures, such as reducing the glazing area and the infiltration rate, are also reported. (author)

Current data on hypertension in the Kingdom of Saudi Arabia are lacking. We conducted a national survey to inform decision-makers on the current magnitude of the epidemic. We measured systolic and diastolic blood pressure of 10,735 Saudis aged 15 years or older and interviewed them through a national multistage survey. We used multivariate logistic regressions to describe sociodemographic characteristics and risk factors of hypertensive, borderline hypertensive, and undiagnosed hypertensive Saudis. We found that 15.2% and 40.6% of Saudis were hypertensive or borderline hypertensive, respectively. Risk of hypertension increased among men, with age, obesity, diabetes, and hypercholesterolemia. 57.8% of hypertensive Saudis were undiagnosed. These were more likely to be male, older, and diagnosed with diabetes. Among participants diagnosed with hypertension, 78.9% reported taking medication for their condition. About 45% of participants on medication for hypertension had their blood pressure controlled. The prevalence of hypertension and borderline hypertension is very high in Saudi Arabia. Moreover, control of hypertension is poor. With the majority of hypertensive Saudis being unaware of their condition, a national plan is needed to increase utilization of freely available screening, preventive, and medical services.

Full Text Available Higher education sector in Saudi Arabia had a phenomenal growth over the last decade. This study sets out to empirically examine the technical and scale efficiency of government universities in Saudi Arabia. In general, the technical efficiency of Saudi public universities appears to be high. However, majority of public universities relative performance is a dismal when the scale efficiency is taken into consideration. Only two universities out of the total sample of twenty are on the frontier in comparison to five universities based on the VRS efficiency.

Saudi Arabian oil policy is analyzed by using a cartel model where Saudi Arabia's oil production is a function of oil price and oil production in other OPEC countries. Elasticities for oil production and oil price are estimated covering oil crises and 3 intercrises periods. During all intercrises periods, production elasticity is not significantly different from 1 which, to a considerable extent, shows that the oil production in Saudi Arabia followed that of the other OPEC countries. During oil crisis periods, production elasticities were either significantly negative or not significantly different from zero. In most cases, the price elasticity was not significantly different from zero. (au)
This study provides a descriptive epidemiological data of thyroid cancer cases diagnosed from 2001 to 2008 among Saudi women, including the frequency and percentage of cases, the crude incidence rate (CIR) and the age-standardised incidence rate (ASIR) stratified by the region and year of diagnosis. This is a retrospective descriptive epidemiological analysis of all Saudi thyroid cancer cases recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008. The statistical analyses were applied using descriptive statistics with the Statistical Package for the Social Sciences version 20.0. A total of 2,930 cases were recorded in the SCR between January 2001 and December 2008. The region of Riyadh in Saudi Arabia had the highest overall ASIR at 9.43 per 100,000 women, followed by Tabuk at 7.11 and eastern region at 6.5, while Jazan and Jouf had the lowest average ASIRs at 1.97 and at 2.72, respectively. The region of Qassim recorded the greatest changes of ASIR at 5.5 per 100,000 women from 2001 to 2008. There was a slight increase in the CIRs and ASIRs for thyroid cancer in Saudi Arabia between 2001 and 2008. Riyadh, Tabuk and eastern region were the highest overall ASIR in Saudi Arabia. While, Jazan and Hail had the lowest rates. Finally, the region of Qassim had the highest changes in CIR and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of thyroid cancer disease among Saudi women. PMID:24859807

The atmospheric turbidity has been calculated and averaged for 29 places around the Kingdom of Saudi Arabia by using a nine years solar radiation data covering the period from 1971 to 1980. The turbidity values were found to range from 0.1 to 0.4, and the overall average of the turbidity was 0.281±0.056. The minimum value was in Sirr-Lasan (0.168±0.028) and the maximum value was 0.474±0.090 in Riyadh. The low value of the turbidity indicates that the sky of Sirr-Lasan (2100 meter above sea level) may be the clearest sky in the country if the turbidity is taken to be the main factor in preliminary site selection for astronomical observatory. Correlations between the turbidity and geographical coordinates have been investigated and have shown a weak relation between them. Also, seasonal variations studies have shown no significant distribution, which means that each station has its own trend. The low values of the turbidity indicate that the Saudi Arabian sky has relatively small disturbance in the atmosphere.

The Kingdom of Saudi Arabian (KSA) has a substantial water shortage problem where water demand far exceeds water resources sustainable yields. This fact has motivated the Ministry of Water and Electricity (MOWE) to launch a massive water conservation awareness program to enhance water-using efficiency in the country. The MOWE among other water awareness activities has introduced a four-stage program of free distribution of water conservation tools. This research reviewed the domestic water conservation awareness program in Saudi Arabia and assessed the program performance through conducting questionnaire surveys. The latter was designed and implemented in Al-Khobar city in the Eastern Province to measure public awareness regarding water issues. The survey started on April 28, 2012, and continued for 3 weeks. A total of 197 questionnaires were completed. The survey results showed a relatively low awareness among respondents about water shortage problem in the Kingdom. A low percentage of respondents have water conservation tools installed in their houses, but a high percentage is willing to buy and install water conservation tools. The majority of respondents consider the water price low and are willing to pay more for water. The respondents' feedback highlighted the need to improve the current water conservation awareness program.

Full Text Available Sleep medicine is a relatively new specialty in the medical community. The practice of sleep medicine in Saudi Arabia (KSA began in the mid to late nineties. Since its inception, the specialty has grown, and the number of specialists has increased. Nevertheless, sleep medicine is still underdeveloped in the KSA, particularly in the areas of clinical service, education, training and research. Based on available data, it appears that sleep disorders are prevalent among Saudis, and the demand for sleep medicine service is expected to rise significantly in the near future. A number of obstacles have been defined that hinder the progress of the specialty, including a lack of trained technicians, specialists and funding. Awareness about sleep disorders and their serious consequences is low among health care workers, health care authorities, insurance companies and the general public. A major challenge for the future is penetrating the educational system at all levels to demonstrate the high prevalence and serious consequences of sleep disorders. To attain adequate numbers of staff and facilities, the education and training of health care professionals at the level of sleep medicine specialists and sleep technologists is another important challenge that faces the specialty. This review discusses the current position of sleep medicine as a specialty in the KSA and the expected challenges of the future. In addition, it will guide clinicians interested in setting up new sleep medicine services in the KSA or other developing countries through the potential obstacles that may face them in this endeavor.

Objective was to report the allergic fungal sinusitis (AFS) in children in Saudi Arabia and to review the experience of King Abdul-Aziz University Hospital in diagnosis and management of AFS in children. Hospital charts of 45 children reviewed retrospectively. Clinical presentation, radiological and operative findings, management and outcomes studied. Only 25 patients had >-4 diagnostic criteria, treated endoscopically between January 2000 and December 2005 and followed at least 2 years in KAUH, Riyadh, Kingdom of Saudi Arabia. Twenty-five patients had at least 4 criteria for AFS> All patients underwent functional endoscopic sinus surgery (FESS) with high recurrence rate 44%. Twenty-eight percent needed revision surgery even with medical treatment post operatively. Moreover, no other complications were reported in this study. Aspergillus spp is the most common fungal type in our review. Allergic fungal sinusitis in children is underestimated and understudied associated with poor outcome and high recurrence because of difficulty in management. Therefore, the most effective approach of AFS management in children is to have a high index of suspicion, adequate, preoperative evaluation, medical preparation preoperatively, meticulous surgery, medical management, postoperative including topical and systemic corticosteroids and close clinical follow-up with endoscopically guided debridement.

BK human polyomavirus (BKV) causes an asymptomatic primary infection in children, but later, establishes latency mainly in the urinary tract. Virus-host interactions influencing persistence and pathogenicity are not well-understood. We present here a 12-year-old Saudi boy, who had renal transplant in Egypt. Seven months later, he was admitted to our Pediatric Nephrology Unit as a case of renal impairment. He developed BKV infection, diagnosed and successfully managed in our hospital. This case demonstrates the expanding clinical importance of BKV in a post renal transplant patient. This virus can be detected in transitional cells in the urine (decoy cells) using cytology. Testing for BKV deoxyribonucleic acid in urine and blood is an early detection assay, and can be used as a screening test in the early stages. The early reduction of immunosuppression can improve the prognosis. No specific antiviral treatment has been established yet. This is the first report of detecting BK virus in a Saudi post-transplant child in urine and blood specimens by using polymerase chain reaction. (author)
Identifying the predictors of smoking in one of the top cigarette-consuming countries in the world is a vital step in smoking prevention. A cross-sectional study assessed the predictors of smoking in a cohort of male students in 3 universities in Saudi Arabia. A pre-tested, validated questionnaire was used to determine sociodemographic characteristics, academic performance, peers' smoking, and presence of a smoker within the family. Of the 337 participants, 30.9% were current smokers (smoked 1 or more cigarettes within the last 30 days). Lower academic performance (OR = 2.29, 95% CI: 1.02-5.17), peer smoking (OR = 4.14, 95% CI: 1.53-11.3) and presence of other smokers in the family (OR = 2.77, 95% CI: 1.37-5.64) were the significant predictors of smoking status identified using multiple logistic regression analysis. These findings highlight the influence of family and peer pressure in initiating cigarette use among the youth of Saudi Arabia. PMID:24673080

Full Text Available An analysis has been carried out on the chorological units of Saudi Arabia. Three chorological units have been identified within the country, based on the richness of endemism. They are: Saharo-Sindian regional zone, Somalia-Masai regional centre of endemism and the Afro-montane archipelago-like regional centre of endemism. The Saharo-Sindian regional zone is divided into three subzones; of which, Nubo-Sindian local centre of endemism and the Arabian regional subzone are present in the Kingdom. The boundary line of the Nubo-Sindian local centre of endemism within Saudi Arabia has been extended towards the eastern region to cover most of the regions in the western Najd. The Somalia-Masai region contains the highest percentage (25.66% of species. The highest number of uni-regional endemics per unit area is found in the Afromontane archipelago-like regional centre of endemism while the lowest of that is in the Arabian regional subzone.

Full Text Available Pegmatite is the main source of feldspar for ceramics industry. Usage of pegmatite in ceramic industry causes some problems due to the presence of mica and iron oxides. These materials reduce tile strength, hardness and density of the final product leading to low quality ceramic products. Southern Saudi pegmatite separation treatment was carried out in two phases in order to improve the ceramic quality of the feldspar obtained from this pegmatite. The first phase consists of gravitational separation to remove the heavy impurities and in the second phase magnetic separation was carried out to further minimize iron content. Porcelain ceramic batches were prepared by wet-mixing, drying, pressing (semi-dry press and fired at temperatures from 1000 to 1350 °C. The porcelain ceramic bodies were prepared and examined by DTA, X-ray diffraction, SEM and tested for bulk density, linear shrinkage, water absorption and flexural strength. These results indicated that, after treatment (gravity and magnetic separation, the pegmatite can be considered as a good source of potash feldspar. The present study provides a positive indication for using of Southern Saudi pegmatite after treatment in ceramic industries.

Full Text Available Neem (Azadirachta indicaA.Juss. is a multipurpose agroforestry tree that is well adapted to a wide range of climatic and soil conditions and has gained worldwide recognition for its pharmaceutical and pesticidal properties.The world's largest pure Neem plantations are available in the plains of Arafat, Saudi Arabia where 50,000 thousands Neem trees were planted to provide shade from the blazing summer sun for the millions of Hajis (Muslim pilgrims. Sporadic mature Neem trees are also found in Medinah, Taif and elsewhereof the Kingdom. The Neem tree is adapted to Arafat under harsh climatic conditions of Saudi Arabia and the plantation may be extended to other parts of the Kingdom as a avenue tree and also to minimize the desertification under changing climatic conditions and to improve the environmental condition of the country. At Arafat mixed plantations may be advocated to save the present plantation which may come from climate change as well as pest and diseases problems. So care must be taken to monitor the diseases of Neem tree at Arafat on a regularbasis. Because of insufficient growth of Neem at Arafat the methods of green cultivation with microbial inoculants, organic fertilizers, mycotrophic green manure plants may be practiced for successful plantation.

Patients on hemodialysis experience considerable psychological and physical stress due to the changes brought on by chronic kidney disease. Religion is often turned to in order to cope with illness and may buffer some of these stresses associated with illness. We describe here the religious activities of dialysis patients in Saudi Arabia and determined demographic, psychosocial, and physical health correlates. We administered an in-person questionnaire to 310 dialysis patients (99.4 % Muslim) in Jeddah, Saudi Arabia, that included the Muslim Religiosity Scale, Structured Clinical Interview for Depression, Hamilton Depression Rating Scale, Global Assessment of Functioning scale, and other established measures of psychosocial and physical health. Bivariate and multivariate analyses identified characteristics of patients who were more religiously involved. Religious practices and intrinsic religious beliefs were widespread. Religious involvement was more common among those who were older, better educated, had higher incomes, and were married. Overall psychological functioning was better and social support higher among those who were more religious. The religious also had better physical functioning, better cognitive functioning, and were less likely to smoke, despite having more severe overall illness and being on dialysis for longer than less religious patients. Religious involvement is correlated with better overall psychological functioning, greater social support, better physical and cognitive functioning, better health behavior, and longer duration of dialysis.

Full Text Available Due climatic variability and anthropogenic changes, floods have been raised lately in several regions worldwide. The resulting impact from floods is often harmful. This can be applied to Saudi Arabia, the country which is known by dry climatic conditions, and it became lately a typical region for such natural hazard. Hence, floods are observed as a yearly disaster with high magnitude of influence. Jeddah, a coastal Saudi city on the Red Sea to the west, has witnessed severe event in November 2009, when flooded water and sediments (torrents invaded the urban areas and resulted decease of many people and destroyed the infrastructure and civilized zones. The lack of mitigation implements exacerbated the problem. This study implies an assessment of flood hazard risk in Jeddah region. It aims to identify the zones subjected to flood and then inducing the influencing factors at different levels of effect. For this purpose space techniques were utilized, with a focus on IKONOS satellite images, which are characterized by high resolution in identifying terrain features. In addition Geographic Information System (GIS was also used to support space techniques. Thus, damaged areas and the mechanism of flooding process were recognized. This helps avoiding further urban expansion in areas under flood risk and will aid decision maker to put new strategies for hazard management.

With the evolution of health services in Saudi Arabia, there has been increase in the number of medical practice litigations. The author analyzed the medical malpractice litigation that was referred to the National Medico-Legal Committee (MLC) in order to evaluate the magnitude and underlying factors of the problem in Saudi Arabia. A retrospective analysis of the official records of Medico-Legal malpractice over the period 1420H-1424H (199-2003) was performed. The incidence among different medical specialties, location, and final resolution of each claim were identified. Data analysis revealed an increasing trend in the total number of claims over the study period, with a sharp increase in the transition between 1422H and 1423H (2001-200). The distribution of claims over different medical specialties showed that obstetrical practice took the lead with 27%, followed by general surgery and subspecialties, represented by 17% each, internal medicine 13%, while pediatrics contributed 10% of claims: the fewest claims were in dentistry with 2.5%. The majority of claims were referred to the Ministry of Health and private sectors medical facilities. Most claims were from the Riyadh region over the period between 1420H to 1422H (1999-2001), while thereafter, during 1423 and 1424H (2002 and 2003), the Holy Capital had the highest number of claims referred to the MLC. Adherence to standards of medical practice is by far the best approach to avoid or reduce the incidence of litigato avoid or reduce the incidence of litigation. (author)
Human hydatid disease is caused by Echinococcus granulosus. Its distribution is world wide and it affects mainly the liver, but other organs could be involved. Primary involvement of pelvic organs is very rare. This is a case report of primary ovarian hydatid disease in a postmenopausal woman, diagnosed postoperatively. Surgical excision was adequate. Ultrasonography, particularly high frequency trans-vaginal, computed tomography scan and, more recently, magnetic resonance imaging are more frequently used in the diagnosis of Echinococcus cyst. They appear more reliable than many of the old tests of varying sensitivities. Whereas, there are anecdotal reports of obstetric and gynecological manifestations of echinococcosis from some Middle Eastern and North African countries, this is the first of such report from the Kingdom of Saudi Arabia. It is unclear why there is a lack of information about this condition among Saudi women, even though socio-cultural attitude to female involvement in sheep farming and animal husbandry is similar to that in other Arabic and Islamic countries. We endorse the recommendation that every gynecologist, radiologist and histopathologist should maintain a high index of suspicion for hydatid cyst, whenever a septate cystic pelvic mass is found.

The growth of research biobanks has created many new ethical challenges worldwide. This article outlines and discusses key issues in the governance of Saudi Biobank, a newly established national biobank in Saudi Arabia launched in 2014. The Saudi Biobank project includes human biological samples from participants aged 10-70 years and aims to conduct an extensive study on the influence of genes, environment and lifestyle in common diseases. We examined the strengths and weaknesses of Saudi Biobank's governance as well as the similarities and differences with 4 other biobanks (in the United Kingdom, Iceland, Estonia and Canada). Three different ethical issues are discussed in detail: confidentiality, informed consent and children's participation in research. We evaluated these issues in relation to international ethical guidelines and Islamic law. The insights gained may be useful in developing national biobanking regulations in other Islamic countries, particularly in countries of the Eastern Mediterranean Region. PMID:25601806

Full Text Available This study aims to explore whether Saudi listed companies are using performance measures to evaluate their internal audit function and, if they are, what performance measures they use to evaluate internal audit function and the identity of the important measures from the perspective of internal auditors. A questionnaire was designed and distributed to internal auditors in Saudi listed companies. The results show that Saudi listed companies are using both quantitative and quantitative performance measures to assess the internal audit function performance. Also, we find that internal auditors rank quantitative measures as important while qualitative measures are ranked as unimportant. The current study contributes to the existing literature by identifying key performance measures for the internal audit function in an emerging market, and provides valuable information about how to measure internal auditing performance. Also, this study is considered as the first one in Saudi market that identify such variable.

To describe the clinical features and presentations of perinatal stroke in a prospective and retrospective cohort of Saudi children and ascertain the risk factors. Patients with perinatal stroke were identified from within a cohort of 104 Saudi children who were evaluated at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia from July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Neuroimaging for suspected cases of stroke consisted of cranial CT, MRI, or both. During the study period, 23 (22%) of 104 children (aged one months to 12 years) were diagnosed to have had perinatal stroke. The male: female ratio was 1.6:1. Ten (67%) of the 15 children who had unilateral ischemic involvement had their lesion in the left hemisphere. The presentation of the ischemic result was within 24-72 hours of life in 13 (57%) patients, and in 6 children (26%), motor impairment was recognized at or after the age of 4 months. Nine children (39%) had seizures at presentation. Pregnancy, labor, and delivery risk factors were ascertained in 18 (78%) cases. The most common of these included emergency cesarean section in 5 cases, and instrumental delivery in other 5. Screening for prothrombotic risk factors detected abnormalities in 6 (26%) patients on at least one test carried out between 2 months and 9 years of age. Four children (17%) had low protein C, whichur children (17%) had low protein C, which was associated low protein S and raised anticardiolipin antibodies (ACA) in one patient, and low antithrombin III in another. Low proteins S was detected in a 42-month-old boy. The abnormality in the sixth child was confined to raised ACA. The present study highlights the non-specific features by which stroke presents during the neonatal period. The data are in keeping with the potential role for inherited and acquired thrombophilia as being the underlying cause. However, the high prevalence of additional acquired antenatal and perinatal risk factors support a multifactorial disorder. (author)

Full Text Available Background -Risk factors for acquiring hepatitis C virus (HCV infection have been elucidated in many developed countries but the picture is still not clear in many Middle Eastern Countries including Saudi Arabia. Aim -To investigate possible risk factors for acquiring HCV among Saudis. Methods -Various demographic and medical risk factors that might be associated with the spread of HCV among Saudis were investigated. The population studied included 20 anti-HCV-positive with chronic liver disease (CLD, 30 anti-HCV-positive patients without CLD and 272 anti-HCV-negative Saudi blood donors. All people investigated were of the same age group (>40 years of age. Results -None of the demographic parameters studied (type of job, type of housing, education was found to be significantly associated with acquiring HCV infection among our Saudi patients. On the other hand up to 40% of the anti-HCV-positive patients and irrespective of the condition of liver disease had a history of surgery, and 25% of them had a history of multiple injections. Furthermore, at least 20% of our anti-HCV-positive patients had a history of schistosomiasis which is significantly higher than schistosomiasis among the blood donors (P< 0.005. Conclusion -In addition to blood and blood products, schistosomiasis seems to be a possible risk factor for acquiring HCV among the Saudi population. The association between schistosomiasis and enhancement of HCV infection need to be further elucidated.

The objective of this study was to identify risk factors for back pain among health care workers of Saudi Aramco. A validated questionnaire was used to collect information on back pain in the last 12 months as well as relevant risk factors among health care workers at a single Saudi Aramco health care facility. Completed responses were received from 964 of 3,295 workers. Three significant predictors for the presence of back pain were identified: female gender (odds ratio [OR] = 1.9, 95% confidence interval [CI] = 1.3-2.7), Saudi nationality (OR = 2.3, 95% CI = 1.4-3.9), and working as a surgeon (OR = 5.4, 95% CI = 1.4-21.5). Educational level was of borderline significance (OR = 1.6, 95% CI = 0.98-2.7). An interaction between gender and race was identified, with Saudi females being at particularly high risk of reporting back pain (OR = 3.9, 95% CI = 1.8-8.5). Gender, occupation, and nationality were identified as risk factors for back pain, and a particularly high risk was seen among female Saudis health care workers in Saudi Aramco.

Full Text Available Saudi Arabia has witnessed enormous socio-economic changes for the last two decades. Due to this, the standard living of most Saudi people has been improved noticeably. Accordingly, that affects on the consumption expenditure of the Saudi family particularly on the children which has been increased substantially. However, no studies with respect to cost of children have yet been undertaken in Saudi Arabia. This study is to estimate the proportion of expenditure on children, to family’s income in Saudi Arabia by estimating the cost of children in Saudi Arabia; using Jeddah as a case study. In the study, the cost of children is taken to be money expenditure that is the amount that parents actually spent on their children. The study involves a sample of (1500 respondents from the city of Jeddah. Also, explores attitudes and opinions towards certain topics related to cost of children and the family. The study highlights that cost of children rise proportionately to family income, children age, and their numbers.
This article seeks to examine the impact of technology importation on occupational health and safety in both Saudi Arabian and U.S. oil refining industries. Technologies imported to the Saudi oil industry take two forms: hardware (sophisticated equipment to run oil facilities) and software (policies and regulations pertaining to workers' health and safety, and employment rights installed by Aramco's founding multinational companies). This study utilizes qualitative, historically oriented, cross-national case studies to compare and assess workers' health, safety, and rights in Saudi Aramco with its U.S. counterpart, Motiva Enterprises. Two facilities were chosen to conduct field research: the Saudi Aramco oil refinery at Jeddah and Motiva's refinery at Port Arthur, Texas. The Jeddah refinery is fully owned by Saudi Aramco, thus, representing Aramco's health and safety policies and regulations. The Port Arthur refinery serves as a reference case study for U.S. oil refining facilities. The aspects of occupational health and safety in Saudi Aramco--ExxonMobil's joint ventures SAMREF and LUBREF--also are discussed to examine workers' health policies in both companies. The American oil industry made a significant contribution in establishing the Saudi oil industry, with the cooperation of the Saudi government. Despite having outstanding employment benefits schemes in Saudi Aramco, the presence of an organized work force better serves employee participation in Motiva than in Aramco. Safety systems such as Process Safety Management (PSM)--applied in Motiva--partially exist in Aramco to operate hardware technologies safely. Motiva training systems are better through PACE's Triangle of Prevention (TOP). Both companies follow the same pattern of handling occupational injuries and diseases; however, Saudi government agencies (GOSI) are responsible for compensating and treating injured workers. Saudi workers expressed conditional support for the worker committee program proposed by the Ministry of Labor. American and Saudi workers are concerned about the quality and sufficiency of health and safety training, employment promotion, work pressure, and job uncertainty due to continuous downsizing. This article recommends that Saudi social actors increase safety and health awareness in the work environment by providing intensive occupational safety training to the employees (as demanded by Saudi and American workers), improve labor-management relations through establishing strong cooperative contacts with regional and international trade unions, and establish uniform and standard occupational health and safety regulations for Saudi Aramco and its subsidiaries in order to provide an equal level of protection for Saudi workers.

Cutaneous leishmaniasis (CL), an uncommon disorder in South-East Asia, including Bangladesh, often presents as granulomatous plaque on the exposed areas, with a high index of suspicion required for diagnosis. Here we report the first imported case of CL caused by Leishmania tropica in a migrant Bangladeshi worker in the Kingdom of Saudi Arabia (KSA). The case, initially suspected as a case of cutaneous tuberculosis, arrived at specimens reception unit (SRU) of diagnostic labs of icddr,b being referred by the physician for ALS testing for tuberculosis. At his arrival in the SRU, one of the health personnel of the unit who used to work in KSA suspected him as a case of CL. The diagnosis was confirmed by smear microscopy which revealed plenty of amastigotes within macrophages. PCR was performed to confirm the species. He was treated with sodium stibogluconate at Shahid Suhrawardy Medical College Hospital, Dhaka. PMID:25076674

Full Text Available This study report results of a survey conducted in the EasternProvince of Saudi Arabia to explore the procedures and financialtechniques that large-size contractors utilise in replacingequipment. The results indicated that contractors set severalreplacement alternatives that they evaluate by using a set ofvarious qualitative and quantitative factors. The contractors’business objectives, employee safety and morale, and, contractors’image in the industry were found to be the most influentialqualitative factors affecting the decision of equipment replacement.Inflation, downtime, obsolescence, salvage value, and depreciationare among the top quantitative factors that contractors considerwhile making a decision to replace equipment. Because of theirsimplicity and practicality, the net present value, payback period,and the economic life are the most popular techniques that areutilised for analysing the financial issues of proposed replacementalternatives.
A total of 2515 people attending a large military hospital in Saudi Arabia was studied clinically, serologically, and (when appropriate) radiologically for evidence of treponematosis. The indications are that non-venereal endemic syphilis (bejel) is prevalent among the nomadic communities living in rural areas. In contrast, venereal syphilis is much less common, and is found almost exclusively in urban populations. Some of the high risk regions for bejel have been identified, and many people from these locations complained of persistent pain in the legs, which was often associated with radiological evidence of osteoperiostitis of the long bones. Bejel also seems to have become clinically "attenuated" within the last 30 years, with the majority of seroreactors having latent disease. A hypothesis suggesting a reason for this change is put forward, and ways of controlling the infection are outlined. PMID:6487985

This paper presents a brief description of the general emergency plan for accidents involving radioactive materials in the Kingdom of Saudi Arabia. Uses of radioactive materials and radiation sources and their associated potential accident are specified. Most general accident scenarios of various levels have been determined. Protective measures have been specified to reduce individual and collective doses arising during accident situations. Intervention levels for temporary exposure situations, as established in the IAEA's basic safety standards for protection against ionising radiation and for the safety of radiation sources, are adopted as national intervention levels. General procedures for implementation of the response plan, including notification and radiological monitoring instrumentation and equipment, are described and radiation monitoring teams are nominated. Training programs for the different parties which may be called upon to respond are studied and will be started. (author)
Full Text Available The present study explores the relation- ship between the external CSR practices of the organizations and employees’ job satisfaction, employee engagement and organizational cit- izenship behavior in the context of the Saudi banking industry. A positive relationship between CSR and employee job satisfaction, employee engagement and organizational citizenship be- havior related to the organization is observed. However, the organizational citizenship behavior related to individual is found unrelated to CSR. The theoretical foundation of the study is ground- ed in the spirit of social identity theory (Tajfel and Turner, 1979 and social exchange theory (Blau, 1964. The study implies that involvement in ex- ternal CSR may be a determinant for maintaining a motivated and enthusiastic workforce.

Full Text Available This paper analyses the efficiency and performance of post merger using CRAMEL–type variable of selected private banks in India & Saudi Arabia which are initiated by the market forces. The results suggest that the mergers did not seem to enhance the productive efficiency of the banks as they do not indicate any significant difference. The financial performance suggests that the banks are becoming more focused on their retail activities (intermediation and the main reasons for their merger is to scale up their operations. However, it is found that the loan to total Assets and the profitability are the two main parameters which are to be considered since they are very much affected by mergers. Also, the profitability of the firm is significantly affected after merger giving a negative impact on Earnings.

Full Text Available Background and Objectives : Since cervical cancer is reportedly the seventh most frequent cancer in women in Saudi Arabia and the eighth most frequent cancer among women aged between 15 and 44 years, we wanted to determine the prevalence of abnormal cervical cytology among subfertile women attending the reproductive medicine unit of a tertiary care center in Saudi Arabia. Methods : This was a retrospective, cross-sectional, hospital-based study. A Pap smear was done for 241 of 493 (48.9% subfertile women from January 2008 through February 2009. Results : The Pap smear was normal in 166 of 241 patients (67.9%, abnormal in 71 (29.5%, and unsatisfactory for evaluation in 4 (1.7%. According to the revised Bethesda system, epithelial cell abnormality was found in 7 (2.9%, inflammation in 55 (22.8%, and infection in 9 (3.7% patients. Epithelial cell abnormalities were further classified as atypical squamous cells of undetermined significance (ASC-US (n=3, 42.8%, atypical squamous cells of high grade (ASC-H (n=1, 14.3%, low-grade squamous intraepithelial lesion (LSIL (n=2, 28.5%, and glandular cell abnormalities (AGS (n=1, 14.3%. Conclusion : The high prevalence of abnormal cervical cytology in our subfertile women accentuates the need for screening in patients eligible for in vitro fertilization. In addition, a well-organized screening program for cervical cell abnormalities at the national level should be implemented to allow identification of subfertile women at risk so that potentially life-saving measures can be undertaken early.
Full Text Available Evidence-based medical education (BEME is an attitude of mind that entails the creation of a culture in which teachers think critically about what they are doing, look at the best evidence available and on this ba-sis, make decisions about their teaching practice, and subsequently, undertake the necessary revision and change. More medical schools have opened in Saudi Arabia in the last few years than have existed over the last three decades. Currently, the education of health professionals is based on assumption and traditions and rarely on research findings. Medical teaching has evolved from being opinion-based to evidence-based and the art of teaching is rapidly becoming the ?science? of teach-ing. The need for evidence in our teaching and medical education prac-tices is as important as it is in assessing a new therapy. This approach to education is not only associated with better results in terms of better learning, from the side of the students (the consumers, but also has a wider impact on patient care and the community. Moreover, in this age of accountability, litigations and quality assurance, the need for BEME becomes greater. Some suggestions to implement BEME in Saudi Arabia have been put forward and these are the training of medical education professionals in the use the existing information systems, and dissemi-nating information through the creation of a BEME journal (secondary publication that publishes a critically appraised summary of medical education articles that are both valid and of immediate clinical use.
Few studies have addressed racial differences in prostate cancer (PCa) detection between Western and Arabian countries, although PCa has a significantly lower prevalence in Arabic populations compared to Western populations. Therefore, an explanation of this difference is lacking. Serum prostate-specific antigen (PSA) is a valuable marker used to select patients who should undergo prostate biopsies, although the manner in which it is used may require adjustments based on the ethnic population in question. We investigated racial differences in the PCa detection rate between Canadian and Saudi populations. A retrospective analysis was performed of data collected prospectively over 5 consecutive years in urology clinics at the McGill University Health Center (MUHC) and King Saud University Hospital (KSUH). Men who had high (>4'ng/mL) or rising PSA levels and a negative digital rectal examination were eligible. A total of 1403 Canadian and 414 Saudi patients were evaluated for the study; 717 and 158 men, median age 64 and 68 years, were included in the MUHC and KSUH cohorts, respectively, P<0.0001). Median serum PSA, prostate volume, and PSA density values were 6.1'ng/mL, 47.3 g, and 0.12'ng · mL(-1) · g(-1), respectively, for MUHC patients and 5.2'ng/mL, 64.5'g, and 0.08'ng · mL(-1) · g(-1), respectively, for KSUH patients (P<0.0001, t-test followed by one-way ANOVA). In addition, the KSUH group had a significantly lower PCa detection rate among patients younger than 60 years of age and with PSA values <10'ng/mL. PMID:23802226

Full Text Available Objectives: To evaluate the relationship between maternal height of <155 cm and the risk of caesarean delivery due to failure to progress (FTP among nulliparous saudi women. Design: Observational cohort study. Material and Method: A total of 405 term (GA > 37 weeks, uncomplicated singleton nulliparous pregnant women were enrolled on admission to labour room. The patients were divided into two groups based on maternal height, >155 cm (247 cases as control and < 155 cm (158 cases as study group. The medical records of these women were reviewed. Various baseline clinical characteristics were collected. Maternal characteristics and maternal and neonatal outcomes were recorded. Results: Caesarean section rate for all indications was higher among study group than control group (26.6% and 19.4% respec-tively, p = 0.023. Significant difference was observed in the rate of caesarean delivery due to failure to progress (7.3% and 12% in control and study group respectively, p-value 0.038. The rate of caesarean delivery due to failure to progress was highest among those with height 150 - 155 cm (p-value 0.022. Mean birth weight was significantly higher among control group than study group (3137 ± 403 g and 3030 ± 408 respectively, p-value 0.010. Conclusion: Term singleton nulliparous Saudi pregnant women with maternal height 151 - 154 cm were associated with a greater likelih-ood of caesarean section for failure to progress. Women with height <150 cm did not have increased cesarean section rate. However, mean birth weight was significantly lower in this group.
This study examined current level of information technology integration in science education in the Yanbu school district in Saudi Arabia, and barriers to use. Sub-domains investigated included: infrastructure and resources, policy and support, science teachers' personal beliefs, and staff development. Survey determined demographic data and level of technology implementation, personal computer use, and current instructional practice. Mean frequency of information technology use was 1--2 times during a semester. Science teachers rated barriers limiting use of technology in teaching with a scale ranging from 0 (does not limit) to 3 (greatly limits). Results found all four factors were significant barriers: infrastructure and resources (M = 2.06; p teachers' personal beliefs regarding technology (M = 1.15; p Teachers who received in-service training programs used IT significantly more frequently than those who did not receive any training (t = 2.41, p = 0.017). Teachers who received both pre-service and in-service training used IT significantly more frequently than those who did not receive any training (t = 2.61, p = 0.01). Low technology users perceived that there was no support or incentives for using technology, while high technology users did not perceive these barriers (r = -0.18, p = .01). High technology users had positive personal beliefs about how information technology benefits learning, while low technology users held negative beliefs about technology use (r = -0.20, p = .003). The more barriers science teachers experienced, the less likely they were to be information technology users (r = -0.16, p = .02). There is a need for more computers in school, more teacher training, more time for teachers to learn to use technology, and more readily-available, technical support staff. Further studies are needed to represent all science teachers in Saudi Arabia, assess technology capacity of all schools, and assess in-service staff development strategies.

Full Text Available Objectives: To investigate and define the ideal aesthetic nasal dorsum measurement in the Saudi population. Methods: This observational study was conducted from January to December 2012 at the Department of Otolaryngology, Head and Neck Surgery, King Abdulaziz University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia. A total of 127 raters, 56 males and 71 females were asked to choose the most ideal profile view from one male and one female photograph, whose nasolabial angle were fixed at 90 degrees for the male, and 95 degrees for the female, and whose level of dorsum was modified with a Photoshop program into 5 variables in relation to a line drawn from the radix to the tip-defining points (anterior of more than 2 mm anterior within 2 mm, at the level of the line, posterior within 2 mm, and posterior of more than 2 mm. Results: Male raters preferred the dorsal level slightly posterior within 2 mm (57.1% for the male photograph, and a straight dorsum (58.9% for the female photograph. For female raters, the slightly concave profile of less than 2 mm was the most preferred (71.8% in males, while for females they gave an equal score for either straight dorsum or posteriorly within 2 mm (47.9%. Conclusion: The findings in this study conclude that males preferred a male of a slight deep dorsum, and a female of a straight profile line. Females preferred the male of slight deep dorsum and a female of a straight profile, or slight concavity.

OBJECTIVE Carbonic anhydrase (CA) II deficiency is a rare autosomal recessive disorder caused by mutation in the CA II gene that leads to osteopetrosis, renal tubular acidosis (RTA), and cerebral calcification. Our aim is to present a patient with the classic triad of CA II deficiency syndrome to enhance the awareness about this rare syndrome. METHODS We describe the clinical and radiological findings of a Saudi woman patient with CA II deficiency syndrome. RESULTS A Saudi woman in her 20s presented to our hospital for evaluation of increased bone density. She was known to have delayed developmental milestone with growth retardation and poor scholastic performance. She had multiple fragile fractures started at the age of 15 involving the lower extremities. A physical examination revealed dysmorphic features and intellectual disability with intelligence quotient (IQ) of 36. The initial blood workup showed a picture of distal RTA with hypokalemia, and the radiological imaging confirmed the presence of osteopetrosis and multiple kidney stones. The combination of osteopetrosis with RTA raised the possibility of CA II deficiency. Therefore, computed tomography (CT) of the brain was done and showed intracranial calcification involving the basal ganglia. She was started on potassium chloride and sodium bicarbonate. In addition, she underwent right-sided percutaneous nephrolithotripsy. Her DNA analysis came to show a sequence variant c.232+1G>A, which was detected in both of the CA II genes (homozygous). CONCLUSION Early recognition of the disease is a key, as an early appropriate treatment institution is essential in order to prevent further complications.

Full Text Available The occurrence of harmful aflatoxins from agricultural products varies with geographic location, farming practices and processing. To date, no data was reported from Saudi Arabia on mycotoxin content of nuts and edible seeds. Forty samples of edible nuts and dried seeds were randomly collected from different locations in Al-Riyadh, Saudi Arabia. Fungi were detected by seed-plate and dilutions plate method and were cultured on glucose-Czapek's agar, sucrose-Czapek's agar and starch yeast agar. Purified fungal isolates were identified morphologically. Mycotoxins were extractedusing chloroform and detected by thin layer chromatography. Bacterial analysis was done using total plate count method. There was a predominance of A. niger and A. flavus in all medium types. Aflatoxin B1 (8.5 µg mL-1 was detected in peanuts containing A. flavus. Aflatoxin B1 (1.7 µg mL-1 and B2 (1.7 µg mL-1 was detected in sunflower seeds containing A. terreus. T2 toxin (2.8 mg mL-1 was detected in pumpkinseeds containing Stachybotrys chartarum and DAS (2.4 µg mL-1 was detected in a salted peanut sample containing Trichthecium roseum. Four nut samples showed contamination with bacteria. Turkish pine seeds and American walnut had total plate counts of 12x10. Pakistani pine seeds and Iranian salted pistachio had TPC of 3x10. Listeria monocytogenes was isolated from American walnut samples. Government authorities for food safety consumption should continue to monitor and set appropriate guidelines and information initiatives for public knowledge on the safety of these agricultural products whole year round.

Full Text Available Background Patient’s rights are worldwide considerations. Saudi Patient’s Bill of Rights (PBR which was established in 2006 contained 12 items. Lack of knowledge regarding the Saudi PBR limits its implementation in health facilities. This study aimed to investigate the knowledge of health professions’ students at College of Applied Medical Sciences (CAMS Riyadh Saudi Arabia regarding the existence and content of Saudi PBR as well as their attitude toward its ineffectiveness. Method A 3-parts survey was used to collect data from 239 volunteer students participated in the study. Data were analyzed by descriptive and analytical statistics using SPSS. Results Results showed that although the majority of students (96.7% believe in the ineffectiveness of patient’s rights, half (52.3% of them had perceptual knowledge regarding the existence of Saudi PBR and only 7.9% of them were knowledgeable about some items (1–4 items of the bill. Privacy and confidentiality of patient was the most common known patient’s rights. Students’ academic level was not correlated to neither their knowledge regarding the bill existence or its content nor to their attitude toward the bill. The majority of the students (93% reported that only one course within their curriculum was patient’s rights-course related. About one quarter (23.4% of the students reported that teaching staff used to mention patient’s rights in their teaching sessions. Conclusion The Saudi health professions students at CAMS have positive attitude toward the ineffectiveness of patient’s rights nevertheless they showed limited knowledge regarding the existence of Saudi PBR and its contents. CAMS curriculums do not support the subject of patient’s rights.

Full Text Available This paper examines if there exists a long run relationship among five macroeconomic variables, consumer price index, industrial output, money supply, exchange rate, oil prices along with the global stock prices proxy Standard and Poor 500 index and Saudi all share stock index. Time series analysis is applied using monthly data from January 1994 to June 2013. Application of Johansen cointegration test finds the existence of a long run relationship among the chosen variables. All macroeconomic variables are found to impact stock prices. Standard and Poor 500 index does not affect Saudi stock prices. Vector error correction model shows the presence of long run causality from the explanatory variables to the stock prices. Short run causality test finds a two-way causality between stock prices and oil prices. Impulse response function shows that industrial production shocks pushes up stock prices while consumer price index shocks pulls it down. Variance decompositions show that historical stock prices are the major driver of Saudi stock prices. This implies that Saudi stock market follows weak form of market efficiency. The results of this paper have important implications for the investors in Saudi stock market.
Full Text Available This study investigates the effects of gender and geographical location on the perceptions of Saudi university students regarding the value of preparatory English programs and their attributes. Data was collected during the fall of 2013 from three sample universities in the Kingdom of Saudi Arabia (KSA using an online survey as the instrument. Participants in the study (N = 479 were all enrolled in similar preparatory year English programs in the kingdom and totaled one hundred eighty-four male students and two hundred ninety-five female students. Encouraging results from this study suggest that Saudi university students do realize the value of a preparatory year English program. In most cases, they share common perceptions about which attributes are needed to insure the success of any such program. In some cases, there are significant differences based on gender and geographical location. While research studies on the specific language skills of Saudi university students are increasing steadily each year, the number of studies on preparatory English programs in Saudi Arabia is limited. This study marks the first kingdom-wide, large-scale quantitative analysis study on the programs themselves.

Full Text Available The study examines writing challenges Emirati and Saudi students face at U.S. universities. Based on a sample of 219, a mixed methods approach was used to analyze responses from the participants. The results of the questionnaire reveal that Less than 31% Emirati and Saudi students feel “comfortable” in completing written assignments. The interviews results indicate that Emirati and Saudi students have different opinions regarding writing difficulties. An Emirati student, stated: “I am worried a lot because writing is not easy. Writing is very difficult for us.” However, a Saudi student expressed the easiness of her writing assignments. Emirati students stated that grammar, word choice and sentence construction are “somewhat easy”; however, Saudi students indicated that grammar, word choice and sentence construction are “Somewhat difficult.” An Emirati student, stated: “Most Arabs students are told that we do not have vocabulary or grammar. For me, grammar is okay but my difficulty is how to choose the appropriate word for a sentence. A female Emirati student expressed her worry for grammatical mistakes, which she tries to correct: “When I write my reports, I have to reread my report again because I am sure I will have some grammatical mistakes because English is not my first language. The study implies that the students need more coursework in academic writing to prepare them for their academic writing in their disciplines. U.S. universities need to increase the visiting hours of writing centers and design more workshops that teach the students about writing in various genres.

Full Text Available Background and Objectives: There are no published data on the chronotypes of young Saudi adults. This study assessed the distribution of chronotypes in college-aged Saudis. Design and Setting: Cross-sectional survey of college students Patients and Methods: A validated abridged version of the original Horne and Ostberg morningness-eveningness questionnaire (MEQr was used to assess the chronotype of 759 subjects. Results: Of 540 (71.1% males and 219 (28.9% females participated in this study ( age range, 18-32 years, 138 (18.2% were "morning-types," 417 (54.9% were "neither-types" and 204 (26.9% were "evening-types." There was no significant gender difference in MEQr typology. In Saudis, particularly males, the frequency of morning typology was somewhat higher than that reported for individuals in similar age groups in some Western countries. Conclusion: Most Saudi college students had no preference for morningness or eveningness and were classified as "intermediate-types." Morningness appears to be slightly more common in Saudis, especially males, than in individuals of some Western societies.
Full Text Available This study aims at describing the system of SPA (Saudi pidginized Arabic as produced by AFEs (Asian foreign expatriates working in Saudi Arabia with specific reference to universal characteristics of reduction and simplification in the system of morpho-syntactic structure of Saudi Arabic. The study is based on data collected through a semi-structured interview technique probing into the features of SPA system. Thirty informants were randomly selected from among expatriates working in Saudi Arabia and belonging to different linguistic backgrounds – Urdu, Hindi, Bengali, Tagalog, Indonesian, and Malayalam- as representatives of AFEs. The study showed that the AFEs tend to use simplified and reduced system of SA in order to communicate with its native speakers. This was reflected in producing variations of sentence word order that are not compatible with the sentence word order of SA, reduced inflectional verb forms and simplified noun phrase lacking agreement within its structure. The study concluded with the following implications: 1 SPA could be considered as an emerging contact variety among Asian expatriates in Saudi Arabic; 2 it has universal characteristics of reduction and simplification as shown in its structural system; 3 substrate languages play an essential role in the formation of the SPA.Keywords: Pidgin, simplification, reduction, SPA, AFEs, SA.

Demirjian's dental maturity scores and curves have been widely used for human age determination. Several authors have reported considerable differences between the true and estimated age based on the Demirjian curves, which have been accounted for by ethnicity. The purpose of the current study was to assess the role of ethnicity-specific dental maturation curves in age estimation of Saudi children. A sample of 452 healthy Saudi children aged 4 to 14 years were aged based on the original French-Canadian Demirjian curves and several modified Demirjian curves specified for certain ethnic groups: Saudi, Kuwaiti, Polish, Dutch, Pakistani, and Belgian. One-way ANOVA and a post hoc Scheffe's test were used to assess the differences between chronological age and dental age estimated by the different curves (P<0.05). The curves designed for Dutch, Polish, Saudi, and Belgian (5th percentile) populations had a significantly lower error in estimating age than the original French-Canadian and Belgian (50th percentile) curves. The optimal curve for males was the Saudi one, with a mean absolute difference between estimated age and chronological age of 8.6 months. For females, the optimal curve was the Polish one, with a mean absolute difference of 7.4 months. It was revealed that accurate age determination was not related to certain ethnicity-specific curves. We conclude that ethnicity might play a role in age determination, but not a principal one.

Hodgkin's disease (HD) is a relatively rare lymphoma that affects younger as well as older persons. It is reported in the Western as well as Asian studies that HD is a rare disease in developing world. It is commoner in males in most of the countries and shows a bimodal pattern of age. The commonest subtype is nodular sclerosis in the west and mixed cellularity in the eastern and developing countries. The present study compares eight years' data of HD as regard age, sex, site of anatomical presentation and subtypes according to WHO classification among Pakistani and Saudi patients. This retrospective comparative study included 211 cases of HD from various institutions of Lahore, Pakistan and 78 cases retrieved from the data of King Abdul Aziz Hospital and Oncology Centre, Jeddah, Saudi Arabia. The analysis of both data of HD showed lack of bimodal age pattern and was common among younger age. Male was the dominating sex. Cervical group of lymph nodes was the commonest presenting site. Mixed cellularity HD (MCHD) was the commonest subtype among Pakistani patients whereas Nodular Sclerotic HD (NSHD) was more common among Saudis. A comparison of the pattern of Pakistani and Saudi data of HD showed lack of bimodality in both. The male sex predominated. Morphologically the MCHD and NSHD were the commonest subtypes in Pakistani and Saudi patients respectively. (author)
Full Text Available Date palm is an important fruit crop in the Kingdom of Saudi Arabia and bears a lot on the national economy. Therefore, the government is paying special attention to date production through price support of low grade variety and providing subsidies to the most important production variables. The main objective of this study was to optimize the net present value of revenue to build a structural function of planting new date trees to explain and measure the investment decision. Because of inadequate information in this area, only the past investment period was considered to determine the effect of past decision on new decision of investment. The government policies, which directed to low grade varieties probably, led to inefficiency as the domestic consumption of dates is very high and growing high quality will lead to higher revenue to farmers with almost the same cost of production. To deal with investment in date palm production locally, Saudi Arabia needs to estimate a very high discount rate to observe any value related or based on the discount rate. The Durbin Watson parameter is significant for both the varieties (Khalas and Ruzaiz at 95% confidence interval (LSD0.05. The past investment appeared very significant for its effect on planting new date trees due to the fact that farmers who planted new trees in the past is continuously carrying with date industry and investing in future. Overall, the investment in tree plantation like date palm is not an easy decision by the farmers, because it needs couple of years spending without revenue. The farmers in the date growing areas were hesitant in providing information about the date variety, number of trees per hectare, tree age, fertilizers, pesticides, land ownership, intercropping, cost of production, total yield, quantity sold and price received. The study suggested further investigations on growing high quality date palms, date production and marketing aspects to harvest maximum profit by the farmers as well as support by the government for facilitating proper market and subsidies to date growers.
Kingdom of Saudi Arabia is a developing country and is rich in natural resources. The export sector plays an important role in the economic growth of a country. Basically, economic growth of a country depends on the nature and type of relationship between exports and domestic economic growth. Modern econometric techniques such as Vector Auto-Regression (VAR), Impulse Response Function (IFR) and the Granger-causality test were applied to determine long-term relationship between exports and domestic economic growth from 1970 to 2005. It was found that the export sector of Saudi Arabia caused a significant effect on the economic growth and a positive influence on other economic activities in the long run. Also, a long-term equilibrium existed among the various macroeconomic variables such as RGDP, RC, RG, RI, RX and RM considered in the study. It is apparent that a steady state condition can be reached between exports and economic growth in Saudi Arabia.
Health care has evolved rapidly in Saudi Arabia, based on a Western model of service that incorporates multidisciplinary professional teams. Social work practice forms part of patient care. Within the cultural context of Saudi Arabia, social work education is developing and so too is the role of the practitioner in the hospital system. However, little is known about how social workers are integrated into the hospital setting. This study explores how Saudi social workers perceive their role and how they describe their practice. A quantitative methodology was employed using a self-administered questionnaire design. Analyses showed a number of perceived limitations that precluded effective performance in practicing social workers; these included difficulties related to updating job skills, followed by a perceived deficiency in current supervisory support.

Abstract Objectives: There were two main objectives of this study: to establish normative values of hand grip strengths for 6-12-year-old children in Saudi Arabia and to compare results with existing Western data. Methods: Five-hundred twenty-five children from the central area of Riyadh, Saudi Arabia, were recruited. Hand grip strength was measured using a standard adjustable electronic hand dynamometer. Results: The grip strength increased with advancing age in both genders, but grip strength for boys was significantly stronger than that of girls. There was no significant difference in hand grip strength according to the type of hand dominance. The hand strength of the Saudi children appeared to be lower than that of Western children. Conclusion: The reported values of hand grip strength will allow therapists to compare scores from typical and atypical children according to the age, gender, and body measures. PMID:25325246

Full Text Available There are seven immunologically distinct serotypes of FMDV (O, A, C, Asia 1, SAT 1, SAT 2 and SAT 3, most of them were detected and identified in different regions of Saudi Arabia. FMDV serotype O was the most frequent strain in last decade. Outbreaks of FMDV repeatedly occur among cattle, sheep and goats in various regions of Saudi Arabia during years 1994, 1995, 2000, 2004, 2005, 2006, 2008 and 2010. Recently, 14 (0.78 % suspected cases of FMDV out of inspected 1800 cows were observed and recorded during Hajj season 1432 H (2011 in Makkah. Prevention and control strategies of FMD in Saudi Arabia particularly during Hajj seasons were discussed.
We evaluated the documentation of ethical conduct (obtaining institutional review board approval and consent and following ethical guidelines) of human subject research studies published in Saudi Arabian medical journals between 1979 and 2007. Studies were classified as retrospective, prospective noninterventional, interventional or survey/interview. Of 1838 studies published in 286 journal issues of 11 Saudi Arabian medical journals, only 0.9% documented the ethical guidelines followed, with a significantly higher rate for studies published after year 2000 (1.7%). Of 821 studies requiring institutional review board approval, 8.6% documented obtaining the approval and informed consent, with a significantly higher rate for interventional studies (19.4%), post-year 2000 studies (19.7%) and studies performed outside Saudi Arabia (15.9%). The low documentation rate suggests editor's lack of rigor and/or investigators' ignorance of guidelines. The higher documentation rate after year 2000 suggests an ongoing improvement. PMID:22891513

Thirteen selected Saudi Arabian plants, belonging to seven different families, were tested for possible anti-inflammatory activity using the carrageenin-induced paw edema model in rats. The methanolic extracts of Vernonia schimperi, Trichodesma trichodesmoides var. tomentosum, and Anabasis articulata exhibited the highest anti-inflammatory activity. The active extracts were further subjected to fractionation with chloroform, ethyl acetate, and n-butanol and tested together with their mother liquor for their anti-inflammatory activity in the same rat model. The most potent fractions were the n-butanol fractions of Anabasis articulata and Vernonia shimperi and the aqueous mother liquor of Trichodesma trichodesmoides. Nevertheless, the three potent methanolic extracts showed higher anti-inflammatory activities than their individual fractions. The antioxidant properties were assessed by their in vitro 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activities. It was concluded that the anti-inflammatory activity is dependent, at least in part, on the reduction of prostaglandin (PGE2) and tumour necrosis factor-alpha (TNF-alpha) levels and cyclooxygenase-2 (COX-2) activity.

Full Text Available BACKGROUND : Bad dietary habits, such as eating high-fat/high-energy food, can contribute to obesity in adolescents, which tends to persist into adulthood. The objective of this study was to determine the level and sources of knowledge about foods and healthy diets among male and female adolescents. METHODS : This was a cross-sectional study of a sample of male (n=1240 and female (n=1331 adolescents from third grade, intermediate and all three grades of secondary school students in the Al-Khobar Area, eastern province of Saudi Arabia. A self-administered questionnaire was used to collect information. RESULTS : Approximately 51% of the male and 65% of the female students recognized unsaturated fats as healthy foods. However, 10% of the males and 8% of females reported saturated fats as healthy food items. About 49% of the males and 66% of the females correctly defined cholesterol. Dietary knowledge of both male and female students on the dangers of unhealthy foods and the benefits of fiber-rich diets was found to be unsatisfactory. The main sources of knowledge about health and disease reported by the male and female respondents were television (58% and 61%, respectively, magazines (31% and 39% and daily newspaper (33% and 34%. Primary health care centers (PHCCs staff were the least source of knowledge (17% and 16%. CONCLUSIONS : Knowledge of healthy diets among school students was inadequate. It is recommended that health education and information about healthy eating habits and lifestyle be included in school curricula.
Full Text Available This study was conducted to determine the prevalence of intestinal parasites among immunocompromised patients in Riyadh, Saudi Arabia. Fecal samples were collected from 136 immunocompromised patients (52 females and 84 males, aged 2 to 69 years. Specimens were fixed with 10% formalin for 30 min (2-3 g fecal-1 and then concentrated by a formalin-ether sedimentation technique. Samples were examined as wet saline mounts and in iodine preparation for detection of protozoan oocysts, cysts, helminthic eggs and larvae. Permanent stained smears were performed for intestinal coccidian parasites by the modified Ziehl-Neelsen technique and the modified trichrome stain. Intestinal parasites were detected in 54 (39.7% most of them (25.7% were with diarrhea. More specifically the following parasites were detected Cryptosporidium parvum 11(8.1%, Giardia lamblia 9 (6.6%, Cyclospora cayetanensis 8 (5.9%, Blastocystis hominis 7 (5.2%, Entamoeba histolytica 7 (5.2%, Entamoeba coli 5 (3.7%, Strongyloides stercoralis 3 (2.2%, Ascaris lumbricoides 1 (0.7%, Hymenolepis nana 1 (0.7%, Dicrocoelium dendriticum 1 (0.7% and Hook worm 1 (0.7%. The most common parasite associated with diarrhea in patients, was C. parvum (p<0.001, followed by G. lamblia, C. cayetanensis and E. histolytica. However, differences between different age groups were statistically non-significant. Similarly, no significant difference in the infection rate were found between male and female patients.

Full Text Available Among one of the most far-reaching influences of the Internet, especially from the perspective of business and market models, is the concept and application of eCommerce. Today, this erstwhile ‘experimental’ commerce model has become a standard platform for streamlining business flows and broadening product outreach. This is validated by the significant emphasis by a number of countries in developing robust eCommerce architectures tailored to suit their economical-social systems. An interesting case study in this perspective is the Kingdom of Saudi Arabia, especially given its emphasis on local, regional and religious traditions. Presently, with a tremendous growth rate in Internet connectivity, the Kingdom is actively moving towards large-scale adoption of eCommerce systems. In 2001, a two year project was initiated to study the present influence of Internet on social, educational and business systems within the Kingdom. One of the major aspects was the analysis of user responses collected over the two-year period through a number of surveys, which were designed based on two prominent behavioural models: Theory of Planned Behaviour and Roger’s Theory of Diffusion of Innovations. The consequent analysis of the results was supported and in some cases verified with linear regression models. This paper reports on the consequent findings, which identify factors that may significantly affect the adoption of eCommerce in the Kingdom.
The study of mosque acoustics, with regard to acoustical characteristics, sound quality for speech intelligibility, and other applicable acoustic criteria, has been largely neglected. In this study a background as to why mosques are designed as they are and how mosque design is influenced by worship considerations is given. In the study the acoustical characteristics of typically constructed contemporary mosques in Saudi Arabia have been investigated, employing a well-known impulse response. Extensive field measurements were taken in 21 representative mosques of different sizes and architectural features in order to characterize their acoustical quality and to identify the impact of air conditioning, ceiling fans, and sound reinforcement systems on their acoustics. Objective room-acoustic indicators such as reverberation time (RT) and clarity (C50) were measured. Background noise (BN) was assessed with and without the operation of air conditioning and fans. The speech transmission index (STI) was also evaluated with and without the operation of existing sound reinforcement systems. The existence of acoustical deficiencies was confirmed and quantified. The study, in addition to describing mosque acoustics, compares design goals to results obtained in practice and suggests acoustical target values for mosque design. The results show that acoustical quality in the investigated mosques deviates from optimum conditions when unoccupied, but is much better in the occupied condition.

Animal fascioliasis has been reported in Saudi Arabia among imported and local sheep. The paper demonstrated the parasitological and clinical features of human fascioliasis in nine out of ten male immigrant manual workers with manifestations suggesting fascioliasis. The sedimentation and Kato-Katz techniques proved effect in diagnosing Fasciola species eggs in human stool. The common clinical features were abdominal distension, flatulence, tender right-upper quadrant and easy fatigability and the least was the tinge of jaundice. Others as right upper quadrant pains, colicky abdominal pains & vomiting, epi-gastric pain and mild fever, and tympanitic abdomen were encountered. Anaemia and eosinophlia were also encountered in the ten patients. Fascioliasis patients (nine) were successfully treated with Mirazid as two capsules (600 mg) on an empty stomach an hour before breakfast for six consecutive days. Follow-up clinically and parasitologically was available in only seven fascioliasis patients who were completely cured. Follow-up for the other two fascioliasis patients was out in hand. Other parasites recovered in the stained (eosin, iodine and Zeihl-Nelson stains) smear stool samples was Entamoeba histolytica, Giardia lamblia and Cryptosporidium parvum. Besides, three were free from intestinal protozoan. The results were discussed on the light of the other work carried out regionally. PMID:16363294

Full Text Available This study assesses the plant communities and environmental factors that govern species, abundance and distribution in Taif area, western Saudi Arabia, using TWINSPAN analysis. Twenty three vegetation groups were identified visual, seven groups dominated by Aerva lanata, Pergularia tomentosa, Arnebia hispidissima, Salsola spinescens, Capparis decidua, Aizoon canariense and Blepharis ciliaris in the sand plains, Calotropis procera, Dipterygium gluacum, Bassia muricata, Haloxylon scoparium, Aerva gavanica, Anthemis melompodina and Coccinea grandis in the valleys, Halothammus bottae, Anvillea gracinii, Euryops arabicus, Dianthis strictus and Ecobolium gymnostachyum in the slopes and Capparis sinaica, Maerua oblongifolia, Salsola kali and Centaurea schimperi in the plateaus. The application of TWINSPAN classified the community types into 10 clusters at level 15. The existence of vegetation discontinuities along the catena`s depended largely on water table depth and salinity. These parameters decline with increasing altitude, whereas, CaCO3 and organic carbon does not vary along well defined large scale gradients. The relationships of the habitat-floristic groups are not simple and hydromorphism interacts in complex way with halomorphism.

Background: Acinetobacter baumannii causes infections of respiratory, urinary tract, blood stream and surgical sites. Its clinical significance has increased due to its rapidly developing resistance to major groups of antibiotics used for its treatment. There is limited data available on antimicrobial susceptibility of A. baumannii from Saudi Arabia. Objectives: To determine the patterns of drug resistance of Acinetobacter baumannii and predisposing factors for its acquisition.Subjects and Methods: In this descriptive study, 72 hospitalized patients infected with A baumannii were studied. The clinical and demographic data of the patients were collected using a predesigned questionnaire. Isolation and identification of A.baumannii from all clinical specimens were done using standard microbiological methods. Antibiotic susce ptibility testing was performed by disk diffusion method recommended by Clinical Laboratory Standards Institute. Results: Majority of the isolates (61.1%) were from respiratory tract infections. A.baumannii isolates showed high drug resistance to piperacil lin (93.1%), aztreonam (80.5%), ticarcillin, ampicillin, and tetracycline (76.4%, each) and cefotaxime (75%). Only amikacin showed low rate of resistance compared to other antibiotics (40.3%). About 36% patients had some underlying diseases with diabetes mellitus (11%) being the predominant underlying disease. Conclusions: High antimicrobial resistance to commonly used antibiotics was seen againstcommonly used antibiotics was seen against A.baumannii isolates. Only amikacin was most effective against it.

This thesis addresses the long-range generation planning problem in Saudi Arabia up to the year 2000. The first part presents various models for electric energy consumption in the residential and industrial sectors. These models can be used by the decision makers for the purposes of policy analysis, evaluation, and forecasting. Forecasts of energy in each sector are obtained from two different models for each sector. These models are based on two forecasting techniques: (1) Hybrid econometric/time series model. The idea of adaptive smoothing was utilized to produce forecasts under several scenarios. (2) Box-Jenkins time series technique. Box-Jenkins models and forecasts are developed for the monthly number of electric consumers and the monthly energy consumption per consumer. The results obtained indicate that high energy consumption is expected during the coming two decades which necessitate serious energy assessment and optimization. Optimization of a mix of energy sources was considered using the group multiattribute utility (MAU) function. The results of MAU for three classes of decision makers (managerial, technical, and consumers) are developed through personal interactions. The computer package WASP was also used to develop a tentative optimum plan. According to this plan, four heavy-water nuclear power plants (800 MW) and four light-water nuclear power plants (1200 MW) have to be introduced by the year 2000 in addition to sixteen oil-fired power plants (400 MW to sixteen oil-fired power plants (400 MW) and nine gas turbines (100 MW)
For usage of radioactive substances, any facility has to register and take license from relevant authority of the country in which such facility is operating. In the Kingdom of Saudi Arabia (KSA), the authority for managing radioactive sources and providing licenses to organizations for its usage is the National Center of Radiation Protection (NCRP). This paper describes the system that automates registration and licensing process of the National Center of Radiation Protection. To provide 24×7 accesses to all the customers of NCRP, system is developed as web-based application that provide facility to online register, request license, renew license, check request status, view historical data and reports etc. and other features are provided as Electronic Services that would be accessible to users via internet. The system also was designed to streamline and optimize internal operations of NCRP besides providing ease of access to its customers by implementing a defined workflow through which every registration and license request will be routed. In addition to manual payment option, the system would also be integrated with SADAD (online payment system) that will avoid lengthy and cumbersome procedures associated with manual payment mechanism. Using SADAD payment option license fee could be paid through internet/ATM machine or branch of any designated bank, Payment will be instantly notified to NCRP hence delay in funds transfer and verification of invoice could be avoided, SADAD integration is discussed later in the document
Background.?Hemodialysis is associated with increased risk of healthcare-associated infections but considered a low-risk setting for human immunodeficiency virus (HIV) transmission. We investigated 3 hemodialysis unit (HDU) patients with new HIV infections to determine whether transmission was hemodialysis-associated and to correct factors that contributed to transmission. Methods.?Each patient was evaluated for HIV risk factors. Blood samples were tested to determine relatedness of HIV strains. Clinical data (gathered over 18 months) was reviewed to identify seroconversions at 12 HDUs. Infection prevention and control practices were evaluated at 14 HDUs. Findings.?No other HIV seroconversions were identified during the study. HIV gag, pol, and env gene sequences were consistent with a clonal relationship. HIV and hepatitis C virus prevalence rates at one HDU 1 (5.7% and 6.5%, respectively) were higher than for 11 other HDUs (0% and 0.15%, respectively). Conclusions.?Sequencing supports either patient-to-patient or common-source transmission. Infections occurred despite Saudi Arabia's low HIV prevalence and national dialysis policies that emphasize stringent infection prevention and control practices. PMID:24846636

Karst phenomena exist in different areas in the Kingdom of Saudi Arabia, causing serious environmental problems that affect urban development and infrastructure (buildings, roads and highways). One of the most important problems are sinkholes, which most of the time consist of unfilled voids. These sinkholes are formed as a result of the chemical leaching of carbonate and evaporite formations by percolating water. Field investigations show that there are many surface expressions of sinkholes in the area; some appear on the ground surface and others are hidden in the subsurface. Geophysical data were collected at the study area using two-dimensional electrical resistivity tomography (ERT) with different electrode spacings to delineate buried sinkholes and associated subsurface cavities. Our findings indicated that the dipole–dipole method using an electrode spacing of 1 m was successful in detecting a known subsurface sinkhole. According to the ERT method the detected sinkhole depth ranges from 2 to 4 m, its height ranges from 2 to 4 m, and its width ranges from 5 to 7 m. Field observation has verified the geophysical data, especially along the profile A-A. Finally, closely spaced ERT profiles were successful in determining the three-dimensional volume of the subsurface sinkhole. (paper)
Objective was to find out the prevalence and relation between osteoarthritis of knees and obesity in Al-Ahsa region, Kingdom of Saudi Arabia (KSA). The study included 243 male and female patients diagnosed with osteoarthritis of knees of knees in between June 2001 to March 2003. All patients were recruited from the Physical Therapy Department, King Fahd Hofuf Hospital, Hofuf, KSA. The clinical diagnosis was supported plain x-rays of knees, and of other joint if needed. The weight and height of all patients were taken using one standard weight and height scale, and body mass index was also calculated and recorded. More than 90.53% of the patients referred with osteoarthritis of knees were obese or overweight. The mean body weight of all patients was 84.61 kg and the mean weight was 1.59 meters. Osteoarthritis of the knees was more in obese female than male patients with a female to male ratio of 2.37:1. Obesity is a disease. The aim of all health professionals and others in the community should be directed to the prevention of this disease and its risk to develop multiple complications. (author)
Full Text Available Air pollution exposure has been shown to be associated with an increased risk of specific cancers. This study investigated whether the number and incidence of the most common cancers in Saudi Arabia were associated with urban air pollution exposure, specifically NO2. Overall, high model goodness of fit (GOF was observed in the Eastern, Riyadh and Makkah regions. The significant coefficients of determination (r2 were higher at the regional level (r2 = 0.32–0.71, weaker at the governorate level (r2 = 0.03–0.43, and declined slightly at the city level (r2 = 0.17–0.33, suggesting that an increased aggregated spatial level increased the explained variability and the model GOF. However, the low GOF at the lowest spatial level suggests that additional variation remains unexplained. At different spatial levels, associations between NO2 concentration and the most common cancers were marginally improved in geographically weighted regression (GWR analysis, which explained both global and local heterogeneity and variations in cancer incidence. High coefficients of determination were observed between NO2 concentration and lung and breast cancer incidences, followed by prostate, bladder, cervical and ovarian cancers, confirming results from other studies. These results could be improved using individual explanatory variables such as environmental, demographic, behavioral, socio-economic, and genetic risk factors.
This work is concerned with the environmental impact of the cement industry in the west of Saudi Arabia represented in two cement plants and one cement depository. The concentrations of natural and artificial radionuclides in samples of cement (raw materials and end product) and soil, collected from the cement plant and its surrounding area, were measured using ?-ray spectrometer employing a HPGe detector. In addition, the levels of 19 major and trace elements were also determined in these samples using the inductively coupled plasma atomic emission spectroscopy. The concentrations of the 238U series isotopes in soil samples show a clear radiological impact of the cement industry upon the environment. Possible contamination with Ca and some other elements in soil samples that are rich with the fine grain size was observed. Cluster analysis of soil samples using convenient attributes shows an obvious evidence of the cement industry impact upon the environment. The hidden effect of the cement industry upon the environment was observed when the convenient measured attributes were used in cluster analysis of soil samples. (author)
The current study was aimed to assess Saudi school students' knowledge, attitude and practice about medicines. A pretested self-administered questionnaire was used anonymously among 15-20 year-old adolescents attending tertiary schools in Taif City, KSA. A total of 1022 students completed the questionnaires. Only 15.4% of the respondents knew the medicines' uses. Most of the students 79.6% affirmed that they used to take medicines after consulting physicians, and 45.1% of the students thought that tablet size affects the medicine's efficacy. More than half of the students knew that high temperatures affect the efficacy of medicines, there was a significant difference between rural and urban areas (P = 0.005). Physicians (50.6%) and community pharmacists (15.7%), were the main students' reliable sources of information about medicines. The majority of the students 70.5% were interested in learning more about medicines. The younger students ?18 years wish to learn more than the older ones (P attitudes about medicines. Low level of knowledge may expose adolescents to health-related problems. Educational efforts are important to improve students' practice toward medicines. PMID:25061406

Full Text Available A field investigation was carried out to determine the Physical and chemical characteristics of Al-Khobar aquifer in the Eastern region of Saudi Arabia. Total Dissolved Solids (TDS varies from 4400 mg L-1 along the Gulf coast on the eastern side to around 1800 mg L-1 on the western side. Sodium (Na is the dominant cation followed by Mg, Ca and K in descending order. Whereas, the anion concentration order is Cl > SO4 > HCO3. Nitrate concentration was found to be higher than the recommended limit for drinking purposes. The Saturation Indices (SI indicated that the regional groundwater is under-saturated with respect to calcite, dolomite, gypsum, anhydrite, halite, pyrite and aragonite minerals and oversaturated with respect to goethite and hematite minerals. The hardness of groundwater is very high as compared to the established standards. The F contents are within permissible limits for drinking. The nitrate contents are within permissible limits for domestic use. Two water types i.e., Na-Ca-Cl-SO4 and Na-Ca-Mg-Cl-SO4 dominate the Al-Ahsa whereas Na-Ca-Cl and Na-Ca-Cl-SO4 water types are dominant in Al-Dammam, Al-Khobar and Al-Qatif areas. Overall, the study provided useful information on some important hydrogeochemical processes in groundwater of the eastern region. Further studies are required to determine heavy trace metals concentration for multiple uses.

Full Text Available This article describes the tremendous efforts made in the field of measles immunization in Saudi Arabia in the past 20 years, from the control phase to the elimination phase. Mandatory measles vaccination with one-dose Schwartz vaccine was introduced in 1982 by a royal decree, a step aimed at increasing vaccine coverage. In 1991, a two-dose schedule was implemented using Edmonston-Zagreb measles vaccine , with a first dose at 6 months to protect children younger than 9 months and a second dose of MMR at 12 months of age to protect those who did not respond to the first dose. A marked reduction in the epidemic peak and a shift of infection to older age were noticed. But the same data showed that 50% of measles cases in the 1- to 4-year age group occurred in vaccinated children. In 1998, with the start of elimination phase, an MMR campaign was launched in two phases, targeting school children in 1998 (secondary schools and in 2000 (primary and intermediate schools. Evaluation of the MMR campaign and surveillance data was reflected in the measles immunization policy by shifting the age of measles immunization to 12 months and to preschool using the two-dose MMR schedule.
Transcutaneous bilirubin measurements, using the Minolta transcutaneous bilirubinometer (TcB), were performed in 68 full-term, healthy Saudi infants. Infants who had exchange transfusion and those under phototherapy were excluded. One hundred and twenty measurements were obtained and compared with serum bilirubin levels measured by the American Optics (A.O.) bilirubinometer. The serum bilirubin range was 3.8-18.4 mg/dl. The results showed that the TcB index correlates well with the serum bilirubin measurement: the regression analysis was: r = 0.878, y = 10.78 + 0.909 x, P less than 0.001. However, the regression line showed that at a serum bilirubin level above 12.9 mg/dl the sensitivity of the TcB was 69% and the specificity 92%, while its positive and negative predictive values were 58% and 95% respectively. There was a fair amount of variability around the regression line which may lead to significant errors in clinical decision-making. Thus, the TcB at present has grave limitations which restrict its usefulness in the newborn. PMID:6210040

Samples were collected from 1025 wells supplying drinking water to the 13 regions of Saudi Arabia and analyzed for radon concentrations. The weighted radon median value for the entire country was found to be 4.62 Bq L(-1) with a range of 0.01-67.4 Bq L(-1). The percentage of samples with radon concentration equal to or greater than 11.1 Bq L(-1) (US EPA proposed MCL) was found to be 19.22%. The range of radon in shallow wells varied between 0.06 and 67.4 Bq L(-1) (median value 5.1 Bq L(-1)) and between 0.06 and 40.9 Bq L(-1) (median value 5.34 Bq L(-1)) for deep wells. However, 50% of the samples had radon concentrations equal to or greater than 4.0 and 2.87 Bq L(-1) for the shallow and deep wells, respectively. Correlation of well depth with radon levels revealed that wells drilled in Saq aquifer consisting of predominantly sandstone with significant shale layers in the upper parts, gave higher median radon levels than in Manjur aquifer which consists of predominantly limestone and sandstone.

Precambrian accretionary orogens largely contributed to continental growth, owing to their high production rates of juvenile crust compared to Phanerozoic accretionary orogens. The Pan-African orogeny is responsible for the evolution and growth of the Arabian-Nubian Shield. The Qazaz metamorphic complex in Saudi Arabia is one of the metamorphic complexes that were exhumed due to the activity of the largest Proterozoic shear zone system on the Earth - the Najd Fault System. The Qazaz complex is an example of an unusual new type of core-complex associated with crustal scale strike-slip faulting. Petrography and thermodynamic modelling were used to study the metamorphic evolution of the complex. The core of the complex records peak metamorphic conditions of 560 - 640 oC and 7-8 kbar. The bounding strike-slip shear zones operated at a temperature range of 400-600 oC while the pressure range varied from 5 to 0.5 kbar over a very short distance within the shear zone. The complex shows exhumation of about 25 km due to the activity of the Najd Fault System.

Full Text Available Businesses today consider mergers and acquisitions a new strategy for their company’s growth. Companies aim to grow through sales’ increase, assets purchase, profits’ accumulation and market share gains. The better way for achieving these targets is by getting into either a Merger or an Acquisition. As a matter of fact, growth through mergers and acquisitions has been a critical part of the success of many companies operating in the new economy. Mergers and Acquisitions are an important factor in building up market capitalization. Based on three detailed and in depth structured interviews with major Saudi Arabian banks it has been found that, Mergers motivated by economies of scale should be approached cautiously. Companies should also approach vertical mergers cautiously because it is often difficult to gain synergy through a vertical merger and firms should also seek out mergers which allow the firm to acquire specialized knowledge. It has also been found that the firms should look for mergers that increase market power and avoid unrelated or conglomerate mergers.

Full Text Available Abstract Learning and teaching are quite interrelated. Teaching can't take place unless the students learn. Teaching is a bi-polar activity. Learning barriers or causes of learning difficulties are quite natural phenomenon in an educational setting. But, when it comes to exert a very adverse effect it becomes crucial. Thus, it is unavoidable to ignore those factors which adversely affect the entire learning process. It is found that the following barriers are some of those that are very influential: social, cultural, parental, attitudinal, motivational, psychological, personal and pedagogical factors that include teacher, action research, teaching strategies, teaching resource, administration etc. The present paper is going to focus on the following: motivation of the students, motivation of the teachers, dedication and commitment, teacher's role, teachers’ preparedness, teaching strategies, training and professional development etc. The case of Saudi Arabia is very important for many reasons. The government is spending a lot of money on education. But, the achievement of learning is not up to the mark. Therefore, it is important to study the effect of such factors on academic achievement. Keywords: Barriers, socio cultural factors, psychological factors, pedagogical factors, the teacher , motivation.

Full Text Available This study investigates the problems of EFL/ESL university students unwillingness to speak and take part in class discussions. Saudi students find it inappropriate to speak in class because of their fear to be seen as verbally challenging their teachers' views openly and publicly. Even when they do, they speak a little. This leads to frustration on the side of the teacher, in addition to the absence of any clear feedback from the students: whether they have/have not understood the lecture. The study proposes an integrative approach addressing this problem by integrating all the four communication skills, in addition to the sociolinguistic factor. It has been conducted at the English Department, Qassim University, KSA. The results show that the students have exhibited a considerable improvement in the oral skills. In short, the integrative approach procedure has been generally useful in overcoming those hurdles of students' reticence to communicate, participate, and interact with one another in class discussions.
Full Text Available This study attempted to investigate Saudi English-major undergraduates studying at Taif University to identify a the types of academic writing Saudi English-major undergraduates carry out at English departments, b Saudi English-major undergraduates' writing problems, c the reasons behind Saudi English-major undergraduates' writing problems and d the solutions to overcome Saudi English-major undergraduates' writing problems. To collect data for this purpose, senior faculty members were interviewed and a 32-item structured Likert-scale questionnaire was developed that was administered to 75 English-major students (sophomores, juniors & seniors studying at foreign languages department, Taif University. Data generated through the questionnaire were subjected to descriptive analyses and mean and standard deviation were recorded using SPSS. The findings of this study reveal that Saudi English-major undergraduates are very weak in writing skills and commit lots of errors in their academic writings and are usually engaged in sentence-level or at the maximum at paragraph-level academic writing and they do not consider it important at this level to write different kinds of essays. It has been strongly recommended that the language courses should be increased to strengthen all the language skills in general and writing in particular, motivate the students to use English with the teachers as well as with each, introduce modern and novel teaching techniques, equip the classrooms with necessary audio-visual aids, diagnose students’ writing problems in the beginning of their studies at university, tailor the course contents according to their needs, introduce group/pair work, peer correction, use dictionaries frequently etc.

Full Text Available Mohammed Al-OmranThe Peripheral Vascular Disease Research Chair and Division of Vascular Surgery, Department of Surgery, College of Medicine, King Saud University, Riyadh, Saudi ArabiaPurpose: Atherosclerotic disease (AD is the leading cause of death worldwide and in Saudi Arabia. Intensive risk reduction therapy plays a major role in reducing adverse cardiovascular outcomes in patients with AD. The level of awareness of this important fact amongst physicians (family physicians, general internists, cardiologists and vascular surgeons in managing these patients in Saudi Arabia is not currently known. This study was conducted to examine the perceptions and knowledge of risk reduction therapy in patients with AD amongst physicians in Saudi Arabia in two clinical presentations; coronary artery disease (CAD and peripheral artery disease (PAD.Materials and methods: We conducted a cross-sectional self-administered survey of 897 physicians at different hospitals in four provinces in Saudi Arabia.Results: The recommended targets of low density lipoprotein-cholesterol (LDL-C, blood glucose, and blood pressure in patients with CAD and PAD were known as 40% and 36%; 70% and 66%; and 32% and 28% of physicians, respectively. The initiation of antiplatelet medications, angiotensin converting enzyme (ACE inhibitors, statins, and nicotine replacement therapy for smokers in patients with CAD and PAD were recommended by 98% and 97%; 52% and 34%; 61% and 56%; and 50% and 43% of physicians, respectively. Compared to other specialties, cardiologists had the lowest threshold for initiating risk reduction therapy, whereas vascular surgeons had the highest threshold.Conclusion: The level of physician awareness of atherosclerosis risk reduction therapy across Saudi Arabia has revealed knowledge and action gaps. A call to action to implement effective strategies to encourage health professionals to use risk reduction therapy and increase public awareness is needed.Keywords: coronary artery disease, peripheral arterial disease, risk reduction, atherosclerosis
A high incidence of respiratory infection, including influenza, has been reported at the Hajj in Mecca, Saudi Arabia. Reported rates of influenza have been higher among UK than among domestic pilgrims, but this could be explained by methodological differences among studies. Accordingly, the present study compared the frequencies of respiratory viruses among UK and Saudi pilgrims using the same study design. Pilgrims with upper respiratory tract symptoms were recruited from Mecca and the neighbouring valley Mina during the Hajj 2006. Nasal swabs were used for point-of-care influenza testing and real-time RT-PCR (rtRT-PCR) tests for influenza virus, rhinovirus, parainfluenza virus, adenovirus, human metapneumovirus and respiratory syncytial virus. Of 260 pilgrims investigated, 150 were from the UK and 110 were Saudi; of these, 38 (25%) UK pilgrims and 14 (13%) Saudi pilgrims had respiratory infections detectable by rtRT-PCR (p 0.01). In the UK group, there were 19 (13%) cases of rhinovirus infection, 15 (10%) cases of influenza virus infection, two (1%) cases of dual infections with influenza virus and rhinovirus, one (3%) case of parainfluenza virus infection, and one (1%) case of respiratory syncytial virus infection. Fifty-six (37%) UK pilgrims had been vaccinated against influenza virus, with the rates of influenza in the vaccinated and unvaccinated group being 7% and 14%, respectively (p 0.19). In the Saudi group, there were three (3%) cases of rhinovirus infection and 11 (10%) cases of influenza. Only four (4%) Saudi pilgrims had been vaccinated against influenza virus, and none of these was infected with influenza virus. Overall, a significantly higher proportion of the UK pilgrims had detectable respiratory infections (25% vs. 13%, p 0.01). Influenza rates were similar in both groups, but the reported rates of influenza vaccination differed. PMID:18373688

Currently, dengue fever is considered as main health problems in Mekkah and Jeddah of Kingdom of Saudi Arabia (KSA) with dramatically increase in the number of cases reported every year. This is associated with obvious failure in the recent control and management programs for the mosquito vector (Aedes aegypti). Here, we suggested promoting the health education and public awareness among Saudi people to improve the control of dengue mosquito vector. Several suggestions and recommendations were highlighted here to ensure effectiveness in the future control and management programs of dengue mosquito vector in KSA. PMID:25403705

Our results show that the most frequent blood group in Saudis is O-positive. Blood group A is observed at a lower frequency relative to values from Western populations, whereas a significant increase in blood group B combined with a slight increase in blood group AB was recorded. Knowledge of the frequencies of the different blood groups in Saudi Arabia is very important for Blood Banks and transfusion service policies. Knowledge of blood group phenotype distribution is also important for clinical studies (for example disease association, as well as for population studies.

Patients and methods: Epidemiological analysis was performed on data from all MERS-CoV cases recorded by the Saudi Ministry of Health between June 6, 2013 and May 14, 2014. The frequency of cases and deaths was calculated and adjusted by month, sex, age group, and region. The average monthly temperature and humidity of infected regions throughout the year was also calculated. Results: A total of 425 cases were recorded over the study period. The highest number of cases and deaths occurred between April and May 2014. Disease occurrence among men (260 cases [62%] was higher than in women (162 cases [38%], and the case fatality rate was higher for men (52% than for women (23%. In addition, those in the 45–59 years and ?60 years age groups were most likely to be infected, and the case fatality rate for these people was higher than for other groups. The highest number of cases and deaths were reported in Riyadh (169 cases; 43 deaths, followed by Jeddah (156 cases; 36 deaths and the Eastern Region (24 cases; 22 deaths. The highest case fatality rate was in the Eastern Region (92%, followed by Medinah (36% and Najran (33%. MERS-CoV infection actively causes disease in environments with low relative humidity (<20% and high temperature (15°C–35°C. Conclusion: MERS-CoV is considered an epidemic in Saudi Arabia. The frequency of cases and deaths is higher among men than women, and those above 45 years of age are most affected. Low relative humidity and high temperature can enhance the spread of this disease in the entire population. Further analytical studies are required to determine the source and mode of infection in Saudi Arabia.

Because there are no reference standards for body mass index (BMI) in Saudi children, we established BMI reference percentiles for normal Saudi Arabian children and adolescents and compared them with international standards. Data from a stratified multistage probability sample were collected from the 13 health regions in Saudi Arabia, as part of a nationwide health profile survey of Saudi Arabian children and adolescents conducted to establish normal physical growth references. Selected households were visited by a trained team. Weight and length/height were measured and recorded following the WHO recommended procedures using the same equipment, which were subjected to both calibration and intra/interobserver variations. Survey of 11 874 eligible households yielded 35 275 full-term and healthy children and adolescents who were subjected to anthropometric measurements. Four BMI curves were produced, from birth to 36 months and 2 to 19 years for girls and boys. The 3rd, 5th, 10th ,25th , 5oth , 75th ,85th , 90th , 95th , and 97th percentiles were produced and compared with the WHO and CDC BMI charts. In the higher percentiles, the Saudi children differed from Western counterparts, indicating that Saudi children have equal or higher BMIs. The BMI curves reflect statistically representative BMI values for Saudi Arabian children and adolescents. (author)
Full Text Available Mesenteric ischemia is relatively a rare disorder seen in the emergency department (ED. Due to the effect of hypobaric hypoxia and higher liability for thrombosis encountered in high altitude areas, acute occlusive mesenteric ischemia (AOMI would represent an actual challenge in Taif and related districts. Another risk factor is that about twenty-five percent of Saudis are victims of diabetes due to the changes in lifestyle and diet leading to increasing levels of obesity. Vague nonspecific clinical findings and limitations of diagnostic studies in addition to cultural and social factors, may lead to late presentation making the diagnosis a significant challenge and in turn higher morbidity and mortality are expected. Objectives: In this study, we review type of AOMI, pattern of presentation, laboratory, radiological, Intraoperative findings and results of treatment in 36 patients who were admitted to King Abdul Aziz Specialist Hospital and King Faisal Hospital, Al Taif, Saudi Arabia from January 2009 to January 2012. Methods: 36 patients with final diagnosis of AOMI were included in this retrospective study by means of review of their files and medical records. Results: The disease was more common in men than women (23 male and 13 females. The mean age of patients was 54 years. The mean time of presentation was 2.4 days after occurrence of symptoms. Abdominal pain was the most common symptom of patients followed by nausea, vomiting, constipation and bloody diarrhea. On physical examination; tachycardia was prevalent, Oliguria was seen in approximately 69.4% of patients, 11.1% of patients were in shock status. All patients had abdominal tenderness and 61.1% of patients had marked peritoneal signs (rebound tenderness with guarding or/and rigidity. Twenty one/36 (58.3% patients were diabetics, 17/36 patients (47.2% were hypertensive and 8/36 patients (22.2% with associated cardiac disorders. In laboratory tests, Leukocytosis was present in all patients. Secondary polycythemia was seen in 38.9% of patients. D-Dimer level was high in all patients. In 61.1% of patients, exploratory laparotomies were done based on clinical, laboratory, abdominal ultrasound and plain x-ray findings without performing CT angiography due to presentation with marked peritoneal signs. In all patients gangrenous lesions were detected during surgery and resection of these parts was done. Gangrene and in turn resection, was extensive in 14/36 patients (38.9% and they developed short bowel syndrome. There were 22/36 patients (61.1% with superior or/and inferior mesenteric vein thrombosis, 10/36 patients (27.8% with superior mesenteric artery thrombosis, in one of them there is associated focal thrombosis of aorta and renal arteries and 4/36 patients (11.1% with superior mesenteric artery embolism. All patients received postoperative anticoagulant therapy. Patients with short bowel syndrome were prepared to receive total parental nutrition (TPN for life. Intra-operative deaths were 3/36 (8.3%.There were 5/36 deaths (13.9% accruing within one month after surgery and all died secondary to sepsis and its sequalae with total deaths of 8/36 patients (22.2%. Conclusion: Acute occlusive mesenteric ischemia (AOMI especially of venous type will represent a challenging problem in Taif and related districts. The surgeon must pay intensive attention to patients presented by unexplained central abdominal pain and he has to be with high index of suspicion especially if it meets with the classic teaching of "pain out of proportion to physical findings ". Early diagnosis, aggressive approach to early resuscitation of the patients, correction of metabolic and hemodynamic derangements, and performing laparotomy as soon as these derangements were corrected would decrease morbidity and mortality. In some patients it is necessary to perform second look operation for re-evaluation of the viability of the intestine

In this paper, the persistency of individual meteorological parameters and the dependency of precipitation on barometric pressure and temperature is studied using climate predictability index. For the accomplishment of the set objective, daily average values of barometric pressure, temperature and total precipitation data for a period of 17 years from eleven locations was used. The Hurst exponents (H) for each of these parameters were calculated using wavelet and rescaled range analysis (R/S) methods. The Hurst exponent was used in turn to calculate the fractal dimension D for corresponding parameter. Finally, these fractal dimensions were used to calculate the climate predictability index PIC in-terms of the barometric pressure predictability index (PIP), temperature predictability index (PIT) and precipitation predictability index (PIR). The calculated Hurst exponents using wavelet methods were all less than 0.5 for all stations which is indicative of an anti-persistence behavior of the parameters in time. The same values calculated using the R/S method was less than 0.5 for barometric pressure and temperature but greater than 0.5 for precipitation data. The climate predictability index showed that in most of the cases the precipitation was dependent on both barometric pressure and temperature predictability indices. In some cases it was more dependent on the barometric pressure index than the temperature and in some casesdex than the temperature and in some cases otherwise. In Saudi Arabia there is no prevalent or established rainy season and the present analysis could not result into concrete results. It is therefore recommended to analyze the data by breaking the entire data set into seasons and further into different years.
To explore the role of radiological examination and certain biochemichal values in diagnosing and assessing severity of nutritional rickets. There were cases of nutritional rickets (age range between 3-36 months) seen at King Abdul-Aziz University Hospital, Jeddah,Kingdom of Saudi Arabia, during the period 1997-1999 were studied. Determinatin of calcium (Ca), phosphate(PO4),alkaline phosphate(ALP),hand and wrist x-rays,were performed for all cases. 60 cases of nutritional rickets were dignosed within 2 years,38.3% of the patients presented with swollen wristand 28.3% with bowleg.The bone profile at the time of diagnosis: Ca=2.33+-0.23,PO4=1.47+-0.40 and ALP=925+-418. Approximately 81.7% of the patients had a normal of Ca level, 18.3% had low serum PO4 level, 98.3%high value of ALP. X-ray studies indicated that,58.3% of patients have active rickets, 35% had minimal changes, and 6.7% showed healed rickets. Among those having active rickets 20% had low PO4 level ,83% had normal Ca vlaue , and 100% had high ALP.The mean value +- Sd of biochemical values in this group : Ca=2.34+-0.24, PO4= 1.45+-0.42,ALP=1067+-452. The later was significantly higher compared to other groups (P=0.004). Radiological examination and ALP remains essential to confirm clinical diagnosis of rickets and assessment of severity. (author)
Naturally occurring radioactive material (NORM) is known to be associated with oil and gas extraction. As part of a comprehensive NORM management strategy, Saudi Aramco needed to determine the extent of NORM contamination associated with their oil and gas operations. As part of that strategy, this study focused on external gamma survey of oil producing wellheads at various locations. The study aimed to: 1-) Identify wellheads with elevated gamma radiation dose rate; 2-) Specify the exact locations of the high dose rates on the wellheads; 3-) Identify the radioisotopes responsible for the high dose rates; and 4-) Propose worker protection requirements during maintenance. The majority (?92%) of the surveyed wellheads showed no enhanced gamma dose-rate above background level. From the remaining ?8%, only a few wellheads showed dose rates between 1,000-3,700 n Sv/h. The study revealed that NORM contamination tends to accumulate at turns of the pipes, around pipe diameter changes, the joints, the back of valves, and at the base of the wellhead. Also, for a given location, NORM build up on the interior of pipework varies over time and continues to migrate down stream until it reaches the Gas and Oil Separation Plants (GOSP). There NORM is expected to accumulate and reside in the form of sludge. Gamma spectroscopy analysis revealed that 226Ra and its progeny are responsible for the high radiation dose rates detected. It was concluded that NORM will not pose significant radiation hazards to workers as long as the tubing and piping are not opened. (author)
We have investigated the Ash Shutbah circular structure in central Saudi Arabia (21°37'N 45°39'E) using satellite imagery, field mapping, thin-section petrography, and X-ray diffraction of collected samples. The approximately 2.1 km sized structure located in flat-lying Jurassic Tuwaiq Mountain Limestone has been nearly peneplained by erosional processes. Satellite and structural data show a central area consisting of Dhruma Formation sandstones with steep bedding and tight folds plunging radially outward. Open folding occurs in displaced, younger Tuwaiq Mountain Limestone Formation blocks surrounding the central area, but is absent outside the circular structure. An approximately 60 cm thick, unique folded and disrupted orthoquartzitic sandstone marker bed occurring in the central area of the structure is found 140 m deeper in undisturbed escarpment outcrops located a few hundred meters west of the structure. With exception of a possible concave shatter cone found in the orthoquartzite of the central area, other diagnostic shock features are lacking. Some quartz-rich sandstones from the central area show pervasive fracturing of quartz grains with common concussion fractures. This deformation was followed by an event of quartz dissolution and calcite precipitation consistent with local sea- or groundwater heating. The combination of central stratigraphic uplift of 140 m, concussion features in discolored sandstone, outward-dipping concentric folds in the central area, deformation restricted to the rocks of the ring structure, a complex circular structure of 2.1 km diameter that appears broadly consistent with what one would expect from an impact structure in sedimentary targets, and a possible shatter cone all point to an impact origin of the Ash Shutbah structure. In fact, the Ash Shutbah structure appears to be a textbook example of an eroded, complex impact crater located in flat-lying sedimentary rocks, where the undisturbed stratigraphic section can be studied in escarpment outcrops in the vicinity of the structure.

Full Text Available The aerobic microbial skin flora of 40 healthy subjects living in Jeddah city (Saudi Arabia was determined. Two age groups: children and adults; including males and females were investigated. Seven sites were studied: forehead, axilla, chest, groin, leg, toe web and anterior nares. The skin was sampled by rubbing the chosen site with a surfactant substance (Tween 80 moistened cotton swab which was dipped back in the surfactant container and the resulted suspension was agitated for one minute. Thirty three microbial species were isolated from the seven sites of the study group, in which Acinetobacter baumannii, Acinetobacter lwoffii, corynebacterium species and Staphylococcus (Staph. aureus dominated among children (30% each. The most other prevalent isolates recovered were Alkaligenes species, Bacillus species, Chryseomonas luteola, Staph. epidermidis, Enterococcus faecalis and Staph. hominis (27.5% each. Organisms including Candida albicans, Enterobacter agglomerans, Escherichia coli, Flavobacterium meningosepticum, Klebsiella oxytoca, Micrococcus luteus, Micrococcus roseus, Micrococcus varians, Micrococcus species, Burkholderia cepacia, Stenotrophomonas maltophilia, Pseudomonas paucimobilis, Pseudomonas fluorescence, Pseudomonas species, Staph. capitis, Staph. cohnii, Staph. saprophyticus, Staph. simulans, Staph. warneri, Staph. xylosus, viridans-type streptococcus and yeasts were also found in different percentage. Higher isolation rates of Acinetobacter lwoffii, Staph. aureus, Alkaligenes species, Corynebacterium species, Chryseomonas luteola, Enterobacter agglomerans, Staph. epidermidis and other coagulase negative Staphylococci were noted in children from the seven sites. However, Chryseomonas luteola, and Pseudomonas species, were found only in the groin area among males. Otherwise, no significant differences were recorded in the isolation rates from each site separately in relation to age and sex. The role of the isolated microorganisms in endogenous, exogenous and nosocomial infections was emphasized.

Full Text Available Money laundering is a silent crime. Its goal is to cover up the source of large sums of money that criminals often gather from their criminal activities. This paper will analyze the situation of money laundering in narcotics as it applies in Saudi Arabia. To achieve this end, the paper will first define important terms such as money laundering and narcotics. It will then explain the relationship between money laundering, narcotics trade, and terrorism activities. This background information will form the base for analyzing the various efforts that the Saudi Arabia nation has in place for countering money laundering in narcotics trade. The paper will then explain the challenges facing these efforts, and the future of money laundering in Saudi Arabia. The largest criminal activity associated with money laundering is terrorism financing. The several terror attacks associated with Saudi Arabia’s terror groups like Al-Qaida have made the government realize the importance of curbing money laundering in an effort to counter terrorism. Thus, anti-money laundering strategies are set in place to address all the avenues of money laundering.

Full Text Available Diabetes mellitus is emerging as a major public health probelm in Saudi Arabia in parallel with the worldwide diabetes pandemic, which is having a particular impact upon the Middle East and the third world. This pandemic has accompanied the adoption of a modern lifestyle and the abandonment of a traditional lifestyle, with a resultant increase in rates of obesity and other chronic non-communicable diseases. The indigenous Saudi population seems to have a special genetic predisposition to develop type 2 diabetes, which is further amplified by a rise in obesity rates, a high rate of consanguinity and the presence of other variables of the insulin resistance syndrome. We highlight the epidemiology, clinical and complications profiles of diabetes in Saudi people. Diabetes is well studied in Saudi Arabia; however, there seems to be little research in the area of education and health care delivery. This is of paramount importance to offset the perceived impact on health care delivery services, to lessen chronic diabetes complications, and to reduce the expected morbidity and mortality from diabetes.

Full Text Available Background and Objectives: In Arab countries, epidemiological data about psychological morbidity among medical undergraduate students are scarce. This study sought to determine whether there was a difference in perceived stress levels of male medical students at Mansoura University, Egypt, compared with male medical students at King Faisal University, Saudi Arabia. Methods: The sample consisted of 304 male medical students in Egypt and and 284 male medical students in Saudi Arabia. The self-reported questionnaire covered four categories, including 15 items, on sources of stress (stressors. The perceived stress scale and hospital anxiety and depression scale were used to measure stress, anxiety and depression. Results: There was no significant difference between the two groups in number of stressors. However, Egyptian students were more likely to cite relationship, academic and environmental problems than Saudis. The prevalence of high stress was nearly equal in both groups. However, anxiety and depression were significantly higher among Egyptian than Saudi students. A logistic regression analysis of independent predictors of severe stress among both groups combined revealed that a satisfactory family income and university-graduated father were independent protective factors. The independent risk predictors were anxiety and number of stressors. Conclusions: Stress, anxiety and depression are frequent among medical students. Counseling and preventive mental health services should be an integral part of the routine clinical facilities caring for medical students.

Inflammatory bowel diseases (IBD) are among the leading cause of financial burden, morbidity and employee absenteeism in developed countries because of their chronic remitting and relapsing courses. IBD is estimated to affect the Canadian economy to the tune of 100 million dollars per year. The data regarding exact prevalence in Asian countries, including Saudi Arabia, is still incomplete as there is underreporting and lack of proper registry of the diagnosed cases. The prevalence of inflammatory bowel disease (Ulcerative colitis, Crohn’s disease) has increased over the last decade in Saudi Arabia due to increased IBD awareness among population, as more patients seek medical help and also due to unknown reasons. There is a need of proper registration of IBD patients and establishment of Crohn’s & colitis foundation of Saudi Arabia (CCFSA) as in other parts of the world. The Crohn’s & colitis foundation of Saudi Arabia will be a forum which will co ordinate IBD treatment and research in the country in addition to health education among IBD population. PMID:23580900
