To determine the frequency of various types of malignant lymphoma (ML) in the Al-Qassim region of Kingdom of Saudi Arabia (KSA) according to recently introduced the WHO classification. For this retrospective analysis, material was available in 385 out of 519 cases diagnosed as ML from 1988-2007. Morphological assessment was followed by immunohistochemistry using a panel of antibodies. The study was conducted at Prince Faisal Oncology Centre (PFOC) of King Fahad Specialist Hospital (KFSH), Buraidah, Al-Qassim, KSA. Out of 385 cases reviewed, 251 (65.2%) had non-Hodgkin lymphoma (NHL) and 117 (30.4%) had Hodgkin lymphoma (HL). Male preponderance (male to female ratio 1.6:1) and a wide age range was observed (6 months to 103 years). B cell neoplasms were the most common NHL seen (81.6%) and diffuse large B cell lymphoma (DLBCL) was the most frequent type of NHL encountered (50.1%). Indolent lymphomas like follicular lymphoma (FL) and small lymphocytic lymphoma (SLL) were rather uncommon (13.2%). T cell lymphoma comprised 18.3% of the NHL. The most common type of HL was nodular sclerosis classical Hodgkin lymphoma (NSCHL) (68.3%). In Al-Qassim region of KSA, NHL is the most common ML seen and DLBCL the most common type. Unlike other parts of KSA and Middle East, NSCHL is the most common type of HL encountered. (author)
Purpose: To determine the prevalence and causes of amblyopia in primary school children in Qassim province, Kingdom of Saudi Arabia (KSA). Materials and Methods: In this cross sectional study, 5176 children, aged 6 to 13 years (mean - 9.53 ± 1.88 years) were evaluated. There were 2573 (49.71%) males and 2603 (50.29%) females. Distance visual acuity (V/A) was tested monocularly using a logMAR chart with and without correction. Cycloplegic refraction was performed in children with reduced vision. To determine the etiology of amblyopia, children were enrolled if there was a difference in V/A of two or more lines between eyes or an absolute reduction in acuity 0.05). The prevalence of amblyopia was statistically significant higher in the older age group (10-13 year) compared to younger age group (6 to 9 years) (P < 0.05). Unilateral amblyopia (3.24%) was more frequent than bilateral amblyopia (0.66%). The most frequent causes of amblyopia were refractive error (94.56%), of which anisometropic amblyopia was present in 77.72%, isoametropic amblyopia in 16.84% and strabismus in 5.44%. Conclusion: The prevalence of amblyopia in Qassim province, KSA, is 3.9% which is similar or higher than other published studies on amblyopia. Anisometropic refractive errors are the most common underlying cause for this population. We recommend implementation of visual screening programs for children with appropriate clinical and social settings for early detection and proper management of amblyopia. PMID:25624680

Full Text Available Well water samples were collected during the period of 1997 to 2009 from seventeen wells to represent Saq aquifer, Qassim Region, Kingdom of Saudi Arabia. The water samples were analyzed to determine their quality for domestic use. The water samples were investigated with respect to Electrical Conductivity (EC, total water hardness and the concentrations of hydrogen (pH, calcium (Ca2+, magnesium (Mg2+, chloride (Cl¯, sulfate SO2-4, nitrate NO?3, fluoride (F¯ and ammonium NH+4. The electrical conductivity increased slowly with time from 1.18 to 1.39 dS m-1, with a mean of 1.31 dS m-1 for all water samples examined. The mean EC complies with the maximum permissible drinking water limits set by the local and international standards. The total hardness for the studied well water is 278.26 ppm as calcium carbonate which was classified as very hard water. Therefore, the water of wells should be softened to react with soap for domestic use. The pH in all water samples ranged from 6.77 to 7.28 with a mean of 7.02. This mean of pH complies well with standard value set for drinking water. The concentrations of the cations and anions follow, more or less, a trend similar to EC with time. The cations (Ca2+ and Mg2+ and the anions concentrations were lower than the maximum permissible drinking water limits. The concentrations of F¯ in the all of colleted samples ranged from 0.29-0.37 ppm with a mean of 0.36 ppm. The mean concentration of F¯ is alarming because it is below the lower permissible limit of 0.6 ppm set by the World Health Organization. So, the water of these wells must be fluorinated before drinking use. The concentration of in all water samples ranged between 0.0 to 0.27 ppm with a mean of 0.22 ppm. In general, the concentration of is alarming because it is higher than the permissible concentration in the drinking water (0.0 ppm.
Full Text Available Radon is a radioactive noble gas of a natural origin that may be found anywhere in soil, air and in different types of water. It is worthy to carry out the distribution of radon (222Rn activity concentration and their annual effective dose exposure in groundwater samples from Qassim area, Saudi Arabia. Radon concentrations were measured by using RAD7 an electronic radon detector connected to a RAD-H2O accessory (Durridge Co., USA. The measured radon concentration ranges from 0.76 to 4.69 Bq L-1 with an average value of 2.8 Bq L-1. The measured values of radon concentration are well in the range within the EPA’s Maximum Contaminant Level (MCL of 11.1 Bq L-1. The total annual effective dose resulting from radon in groundwater of Qassim area were significantly lower than the (United Nations Scientific Committee on the Effects of Atomic Radiation UNSCEAR and World Health Organization WHO recommended limit for members of the public of 1 mSv year-1. The measured values for underground water from the study area suggest that the area is safe for farmers and there is no significant threat to the population as per as radon concentration is concerned.
Background Systemic lupus erythematosus (SLE) is a disease with diverse clinical presentations due to interaction between genetic and environmental factors. SLE is associated worldwide with polymorphisms at various loci, including the major histocompatibility complex (MHC), although inconsistencies exist among these studies. Aims This study was carried out to investigate, the association of HLA-DRB1, DRB3, DRB4, DRB5, and DQB1 alleles in SLE patients and clinical presentations at Qassim, Saudi Arabia. Methods Fifty one patients with SLE—84.3% of whom had kidney involvement were studied in a case control study for HLA-DRB1, DRB3, DRB4, DRB5, and DQB1. Results It was found that DRB3 is a protective gene among Saudi’s against SLE, HLA DRB3, HLA DRB1*11 frequency was increased in patients with serositis with a p value of (0.004), (0.047) respectively, increased frequency of HLA DQB1*3 among SLE patients with skin manifestations with a p value of (0.041), the frequency of HLA DRB1*15 alleles was increased among SLE patients with nephritis with a p value of (0.029), the frequency of HLA DRB1*11 among those with hematological manifestations with a p value of (0.03) and the frequency DRB1*10 was found to be increased among SLE patients with neurological manifestations with a p value of (0.002) Conclusion In contradistinction to what have been found among other populations DRB3 is a protective gene among Saudi’s against SLE. No evidence for a role of the HLA-DRB1, DRB4, DRB5, DQB1 alleles. There was an increased HLA DRB3 frequency with serositis, DQB1*3 skin manifestations, HLA DRB1*15 with nephritis, DRB1*10 with hematological manifestations and DRB1*11 with neurological manifestations.

Full Text Available BACKGROUND: Proper structural foundations for asthma care at primary health care centers [PHCCs], are of essential importance, regarding its management. OBJECTIVE: To assess the adherence of PHCCs to the recommended structural foundation for asthma care. MATERIALS AND METHODS: 35 PHCCs were selected in a cluster random fashion. A questionnaire for structural standards was designed, based on the Saudi national protocol for the management of asthma (SNPMA. A physician and a nurse, each from PHCC, were trained for data collection. Structural facilities deficiency was arbitrarily classified into: least deficient (>75%, moderate to severe deficient (25-75% and most deficient (< 25%. RESULTS: The total population registered, was 131190 [urban: 85701 (65.4%, rural: 45489 (34.6%]. Total registered asthmatics was 4093 [urban: 2585 (63.1%, rural: 1508 (36.9%]. The asthma prevalence rate did not differ significantly between urban (3% and rural (3.3% areas . Structural facilities distribution for asthma care, did not significantly vary among urban and rural PHCCs and none of them fulfilled 100% of the desired standards. The least deficient, were the availability of asthma register and salbutamol, in its various forms. The moderately to severely deficient were the SNPMA, peak flow meter (PFM, nebulizer system, Theophylline and systemic corticosteroid. However, they were most deficient in trained doctors and nurses, record charts for Peak flow meter, spacer, educational material and inhalers of corticosteroid or cromoglycate. CONCLUSION: Proper structural foundations for asthma care at PHCCs, at AL-Qassim region, were below the desired national standards. They were most deficient in trained doctors and nurses, record charts for PFM, spacers, educational material and anti-inflammatory inhalers. Future health directorate strategies have to provide such beneficial interventions for proper asthma care.
Epidemiological studies to determine the burden of skin diseases are important for proper health care planning. The purpose of this study was to find the pattern of skin diseases in our patients attending university-affiliated dermatologic clinics in the Qassim region.We conducted a prospective study of all Saudi patients attending the Qassim University Medical College-affiliated dermatology clinics of the Ministry of Health for a period of 12 months from 1 March 2008 to 28 February 2009.The study included 3051 patients comprising 1786 (58.5%) males and 1265 (41.5%) females. Males outnumbered females (P<.05) (male-to-female ratio, 1.4:1). The mean age (standard error of the mean) of the patients was 25.3 (0.27) years. About 71% of the patients were between 5 and 34 years of age. The top five skin diseases were eczema/ dermatitis (19.5%), viral infections (16.6%), pilosebaceous disorders (14.4%), pigmentary lesions (11.2%) and hair disorders (7.6%). The major disorder in males was viral skin infections (20.0%), while eczema/dermatitis (20.7%) constituted the most prevalent skin disease in females. Seasonal variations were recorded in cases of pigmentary lesions, papulosquamous disorders and protozoal infections.Infectious skin diseases, eczema/dermatitis, pilosebaceous disorders, pigmentary lesions and hair disorders ranked as the top five skin diseases. Appropriate training programs for diagnosing and managing common skin diseases should be initiated for primary healtases should be initiated for primary health care physicians and other general practitioners so as to decrease referrals to dermatology clinics (Author).
This study concludes that the level of awareness of the females of Qassim region regarding breast cancer and BSE is not adequate and a health education program for this subject should be introduced in the region.
Full Text Available The Qassim province is one of the most arid regions of Saudi Arabia, however heavy rainfall events have led to water logging problems in the populated centers like Buraidah mainly as a consequence of construction in low lying areas and valleys. Urban rain storm water logging problem were reported at 4 localities in the Buraidah Municipal area after heavy rainfall in November 2008 and March 2009. The logged water from these sites were directed to 4 manmade lakes however the stagnant water in these lakes posed a serious environmental threat mainly in the form of water borne disease. Keeping this problem in mind, a detailed geophysical investigation in the form of Electrical Resistivity Tomography was carried out using the SYSCAL Pro Unit at these 4 locations with a dipole-dipole configuration. The survey was helpful in delineating the wet zones from the dry ones and based on the interpretations the optimum depth and sites of 4 injections bore-wells were determined at each locality. These injection bore-well would serve the dual propose of getting rid of the stagnant water in these lakes and also recharging the underlying aquifers.

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.

To investigate the prevalence of Rotavirus, Adenovirus, Norovirus, and Astrovirus among Saudi children with gastroenteritis. This study was conducted at the Department of Medical Laboratories, Qassim University during the winter seasons of the years 2004 and 2005. A total of 284 diarrhoeal fecal specimens collected from children were tested for the gastroenteritis causing viruses using enzyme immunoassay. Of the 284 specimens, 142 (50%) were found to be positive for viruses causing gastroenteritis. Rotavirus (66.2%) was the most frequently detected, followed by adenovirus (15.5%), norovirus and astrovirus each with 9.2%. All of rotavirus detected belonged to group A. Eight specimens were found positive by two viruses. The introduction of simple and rapid tests for diagnosis of viruses causing gastroenteritis in our pediatric hospitals will improve patient care by reducing unnecessary treatments and hospital stay for patients.

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
Cervical cancer is a common and an important public health problem for adult women in developing countries. In contrast, cervical cancer incidence is low in Saudi Arabia. High-risk types of human papilloma viruses (HPV16 and HPV18) are the most significant risk factors for cervical cancer. HPV16/18-E6 oncoprotein is associated with HPV etiology, viral persistence and epithelial transformation. Cell cycle protein p16 INK4a (p16) plays an important role in the pathophysiology of cervical carcinomas. The aims of this study were to investigate the expression of HPV16/18-E6 and p16 in uterine cervical carcinomas in Qassim Region - Saudi Arabia, and to relate the results to the established clinicopathological prognostic parameters (age of the patient, educational level, birth control methods, number of pregnancy, smoking status, degree of histological differentiation, clinical stage, and lymph node metastasis) The study included 40 specimens of uterine cervical squamous cell carcinomas diagnosed and confirmed by biopsy. Histopathological classification of cervical tumors cases was performed according to the International Federation of Gynecology and Obstetrics (FIGO). Immunohistochemical analysis for HPV16/18-E6 and p16 were carried out on formalin-fixed paraffin-embedded sections of cervical tissues using avidin-biotin peroxidase method. There was a significant statistical correlation between HPV16/18-E6 expression in cervical carcinoma and nationality, smoking status and size of the tumor. HPV16/18-E6 oncoprotein expression in normal lymphocytes and endothelial cells in the tumor tissues and the adjacent normal cervical tissues suggest the possibility that HPV infection might spread to other organs through blood circulation. P16 expression has been correlated with high grade, stage of cervical SCC and HPV16/18-E6 expression. The current study supports the critical function of p16 and HPV16/18-E6 as specific markers for cervical carcinoma. However the potential for usage of p16 and HPV16/18-E6 as prognostic markers will require detailed follow data for a larger group of patients. PMID:24925218

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)
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

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.

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 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.

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.

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

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)

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).
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

Sedimentological, mineralogical, morphological and geochemical studies of sand dunes from ten locations in Saudi Arabia were conducted in order to determine the differences between them and to find out the provenance and tectonic setting of these sand dunes. Sixty seven samples were collected from different sand dunes types ranging in morphology from linear, barchans, parabolic to stars dunes. In overall, the sand dunes are fine to coarse grained mean grain size, moderately sorted, near symmetrical skewness with mesokurtic distribution characterized sand dunes in most locations. The sand dunes grains are subrounded in all locations except in the Red sea, Qassim, central Arabia and the eastern province which showed sub-angular grains. The main mineral compositions of studied aeolian sand dunes are quartz, feldspar, calcite, and mica. Quartz is the dominant mineral in locations with significant amount of feldspars and mica in Najran, Red sea and Central Arabia locations. Moreover, calcite is present in Sakaka and NW Empty Quarter (Jafurah). Basement related sand dunes in Najran, Central Arabia and Red sea locations are sub-mature in terms of their mineralogical maturity. Whereas, sand dunes in other locations are texturally mature except those from the Red sea which showed sub-mature sand. The sands are classified as quartz arenite, except in the basement related sand dunes in Najran, central Arabia and the Red sea are ranging from sub-arkose, sub-litharenite and lithraenite. Morphologically, parallel to sub-parallel sand ridges with NE-SW orientation occurred in east and north parts of Empty Quarter (Najran and Jafurah) and NW-SE orientation in Dahna and Nafud deserts in central and north regions of Saudi Arabia. Parabolic sand dunes characterized the Nafud desert (Hail, Sakaka, Tayma locations). Barchans and star sand dunes characterize the Empty Quarter (Jafurah). Major, trace, and rare earth elements studies were carried out to determine the composition, provenance and tectonic history of the sand dunes. Geochemical analysis indicated that most of sand dunes are quartz arenite type, except in the Red sea, basement related central Saudi Arabia and Najran areas, the sand dunes are sub-arkoses, sub-litharenite and litharenite. The concentration of major,trace and rare elements showed active continental margins as a tectonic setting of Red sea, basement related Najran and central Arabia sand dune. In contrast, passive continental margins for the other locations. The distribution of major, trace and rare earth elements showed similarity in chemical composition between basement related sand dunes in Red sea, Najran and central Arabia.

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.

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

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.

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.

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.

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 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%.

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.

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.

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.

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.

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. Presentation will entail past, present

Full Text Available Abstract Background During the last few decades, the Kingdom of Saudi Arabia (KSA experienced rapid socio-cultural changes caused by the accelerating economy in the Arabian Gulf region. That was associated with major changes in the food choices and eating habits which, progressively, became more and more "Westernized". Such "a nutritional transition" has been claimed for the rising rates of overweight and obesity which were recently observed among Saudi population. Therefore, the objectives of the current work were to 1 determine the prevalence of overweight and obesity in a sample of male college students in KSA and 2 determine the relationship between the students' body weight status and composition and their eating habits. Methods A total of 357 male students aged 18-24 years were randomly chosen from College of Health Sciences at Rass, Qassim University, KSA for the present study. A Self-reported questionnaire about the students' eating habits was conducted, and their body mass index (BMI, body fat percent (BF%, and visceral fat level (VFL were measured. Data were analyzed using SPSS statistical software, and the Chi-square test was conducted for variables. Results The current data indicated that 21.8% of the students were overweight and 15.7% were obese. The total body fat exceeded its normal limits in 55.2% of the participants and VFL was high in 21.8% of them. The most common eating habits encountered were eating with family, having two meals per day including breakfast, together with frequent snacks and fried food consumption. Vegetables and fruits, except dates, were not frequently consumed by most students. Statistically, significant direct correlations were found among BMI, BF% and VFL (P Conclusions Our findings suggest the need for strategies and coordinated efforts at all levels to reduce the tendency of overweight, obesity and elevated body fat, and to promote healthy eating habits in our youth.

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.

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)

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

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.

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)
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.

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.

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 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.

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.

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

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 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.
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
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.

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)
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.

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)
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 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.

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.

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)
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)

The study analyzes the vegetation along Lake Abha in Southwestern Saudi Arabia. A total of 42 plant species were recorded. The annuals decrease and the biennials and perennials increase along the moisture gradient form the terraces to the free-water zone. Six vegetation clusters were identified. The most important are clusters which were identified by the presence of the following species: Phragmites australis, Juncus punctorius, Typha domingensis, Cyperus rotundus, Datura innoxia, Cynodon dactylon, Cornulaca monacantha and Potamogeton nododsus. Each of these communities has been analyzed by classification and ordination techniques and its habitat described and discussed. (author)
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
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.)

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
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.

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.

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 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. Whether religion leads to or is a result of better mental and physical health will need to be determined by future longitudinal studies and clinical trials. PMID:25316206

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)
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

Full Text Available AIM: To identify the seroprevalence of celiac disease among healthy Saudi adolescents. 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.

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

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.

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)
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 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.

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 ...
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.

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.

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.

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.
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.

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)

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.
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.

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 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

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.

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)
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.
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.

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.

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.

When analyzing the impact of changes in oil and petroleum prices on Saudi Arabia’s economy the results indicate that adjustments in foreign savings, supporting an unchanged real exchange rate in the context of changes in oil world prices, quite effectively can insulate the domestic economy from international price fluctuations. If the economy is forced to adjust to the fall in world prices without offsetting changes in foreign savings, the resulting loss of export earnings and associated de...

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)
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.

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.

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

Full Text Available SciELO Brazil | Language: English Abstract in english This investigation evaluated the epidemiological aspects of scorpion stings in different areas of Saudi Arabia. A total of 72,168 cases of scorpion stings recorded in Ministry of Health Medical Centers in 11 selected areas of Saudi Arabia were analyzed based on area, age, sex, time of sting, sting s [...] ite, treatment outcome, time of year, and scorpion species. Stings occurred throughout the year; the highest frequency was in June (15.08%), the lowest in February (2.52%). Most patients were male (61.8%); the majority of which were more than 15 years old (65.4%). Nocturnal envenomation (47.74%) was more common than diurnal (43.91%); most stings were in exposed limbs (90.95%), mainly in the lower limbs (63%). Most envenomings were mild (74.48%) and all evolved to cure, except for one death. Envenomation was characterized by local pain, erythema, headache, vomiting, and anxiety. This study found that the Leiurus quinquestriatus (Ehrenberg 1828), Androctonus crassicauda (Olivier 1807), and Apistobuthus pterygocercus (Finnegan 1807) were responsible for most of the stings, indicating their medical importance in Saudi Arabia. The study shows low threat to life despite the high number of stings; this is a result of the availability of medical facilities and the multi-center antivenom use in different areas of Saudi Arabia.

Background: Cancer of the cervix has been considered as one of the preventable cancers. This study is the first published research addressing the screening of cancer of the cervix in the eastern region of Saudi Arabia. Aim: This study aims to detect the prevalence of abnormal epithelial changes and its types in the eastern region of Saudi Arabia. Settings and Study Design: A retrospective study was designed to evaluate all previously conducted cervical smears examined at a secondary care maternity hospital in Saudi Arabia, during the period from 2003 to 2010. During this period, a total of 1171 smears were reported. Materials and Methods: We analyzed the records of all patients who had undergone Papanicolaou (Pap) smear during this period. After data collection, all cases were recorded as per Bethesda nomenclature. Results: A total of 624 (53.3%) abnormal Pap smears were found, with only 58 cases reported to have epithelial pathological diagnosis (SIL). They represented 4.95% of total taken smears. A majority of the SIL diagnoses in our population were ASCUS, representing 60% of SIL cases. The prevalence of squamous cervical carcinoma was 0.34%. Conclusion: The study has shown a relatively high prevalence of epithelial abnormalities in cervical smears in the studied population. The squamous cell carcinoma represented a higher than the overall prevalence compared to World Health Organization (WHO) factsheets about Saudi Arabia. The mean age of epithelial abnormalities and squamous cell carcinoma was in the reproductive years. PMID:22090690

Full Text Available Air quality deterioration in urban areas; high energy demand and consumption due to regional population growth and economic development; concerns about safe drinking water supplies due to a scarcity of fresh water; air quality deterioration, industrial pollution, waste management, and pollution in coastal areas; and subsequent stress on marine ecosystems are all major environmental challenges being faced by the Kingdom of Saudi Arabia. For effective protection of the environment, an interdisciplinary approach within a sustainable framework, which integrates human needs with economic development and environmental protection, is required. This paper presents an overview of Saudi Arabia’s major environmental problems and challenges and offers opportunities to use economic growth, social equity, and protection of the environment as interrelated components. The role of active participation by governments, stakeholders, businesses, academic institutions, and individuals in the decision-making process and an inter-disciplinary research approach will be identified for each major environmental issue.
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

Saudi Arabia is a major oil-producing nation facing a rapidly-growing population, high unemployment, climate change, and the depletion of its natural resources, potentially including its oil supply. Technology transfer is regarded as a means to diversify countries' economies beyond their natural resources. This dissertation examined the opportunities and barriers to utilizing technology transfer successfully to build renewable energy resources in Saudi Arabia to diversify the economy beyond oil production. Examples of other developing countries that have successfully used technology transfer to transform their economies are explored, including Japan, Malayasia, and the United Arab Emirates. Brazil is presented as a detailed case study to illustrate its transition to an economy based to a much greater degree than before on renewable energy. Following a pilot study, the Delphi Method was used in this research to gather the opinions of a panel of technology transfer experts consisting of 10 heterogeneous members of different institutions in the Kingdom of Saudi Arabia, including aviation, telecommunication, oil industry, education, health systems, and military and governmental organizations. In three rounds of questioning, the experts identified Education, Dependence on Oil, and Manpower as the 3 most significant factors influencing the potential for success of renewable energy technology transfer for Saudi Arabia. Political factors were also rated toward the "Very Important" end of a Likert scale and were discussed as they impact Education, Oil Dependence, and Manpower. The experts' opinions are presented and interpreted. They form the basis for recommended future research and discussion of how in light of its political system and its dependence on oil, Saudi Arabia can realistically move forward on renewable energy technology transfer and secure its economic future.

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 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

The aim of this study was to provide epidemiological data and summarize the different modalities of management of multinodular goiters (MNG) in the Western Province of Saudi Arabia (KSA). A total of 135 patients had MNG, which were diagnosed by ultrasonography at King Abdul-Aziz University Hospital in Jeddah, KSA between January 2003 and June 2004. The data collected includes the age, gender, physical examination of the thyroid gland ( trifluorothymidine, free thyroxine, free triiodothyronine, thyroid stimulating hormone), ultrasonographic findings and Tc 99 radioiodine nuclear scan of the thyroid gland, fine needle aspiration (FNA) of the gland and antithyroid antibodies. The study group was divided according to the thyroid status: nontoxic euthyroid MNG, hypothyroid MNG and toxic hyperthyroid MNG. The management of MNGs according to patient's clinical presentations and thyroid status was reviewed. The mean age was 39+- 12.66 years with a range of 10-79 years. Forty-two patients (31%), with no history of thyroid cancer, had ultrasound guided FNA; 41(97.6%) of the FNAs were benign. One FNA (2.3%) was positive for papillary carcinoma in a 56-year-old female patient. Thyroid antibodies (anti-microsomal antibodies and anti-thymoglobulin antibodies) were measured in 50 patients (37%). thirty-one (62%)were positive, 11(35%) of which were positive in patients with documented hypothyroidism. All patients with hypothyrodism were treated with levothyroxine ; however, only 25.6ed with levothyroxine ; however, only 25.6% with euthyroid MNG were treated with suppressive doses of levothyroxine. Twelve patients (44.4%) with toxic MNG were treated with antithyroid medications. Radioiodine therapy was not given to any patient with nontoxic MNG; however, 48% of those with hyperthyroid MNG received radioactive iodine treatment. Surgery was carried out 25.6% of patients with euthyroid nontoxic MNG and in 11 patients with toxic MNG (46.5%)and 14.8% of those with a subclinical hyperthyroid MNG refrained from any therapy. They were followed up by their clinician in the outpatient clinic. Serum thyroid stimulating hormone levels, ultrasound and fine needle biopsy were the cornerstones of the diagnostic evaluations of patient with MNG. Review of the management of these patients was comparable to that found in the literature. The treatment strategy was similar to the recommendations by the American Thyroid Society; however, radioactive iodine treatment was not used as a treatment for patients with nontoxic goiters.

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

The distribution of hepatitis C virus (HCV) genotypes in the Western Province of Saudi Arabia is unknown. The purpose of our study was to determine the prevalent HCV genotypes among HCV seropositive Saudi patients in the Western Province and to study the relationship between types/subtypes, clinical status and liver histology. Serum samples were collected from 140 consecutive patients attending the Hematology Clinic with varying grades of liver diseases, high almandine transferees (ALT) for > 6 months, positive HCV, qualitative PCR and who had liver biopsy. HCV genotyping was determined on patients who had tested positive by both HCV enzyme immunoassay (EIA) and the recombinant immunoblot assay (RIBA). Of the 140 patients, 97 (69.2%) had genotype 4, 18 (12.8%) had genotype 1a, and 16 (11.4%) had genotype 1b. Genotype 2b and 5 were found in two patients (1.4%) each, while 5 patients (3.6%) had mixed infections with genotype 4 and 5. Of the 97 patients infected with genotype 4, 84 (86.6%) had chronic active hepatitis (CAH), two (2.1%) had CAH with active cirrhosis, 9(9.3%) had cirrhosis and two (2.1%) had normal liver histology (NLH). The most prevalent HCV genotype in the Western Province of Saudi Arabia was genotype 4 (69.2%). Genotype 1b was encountered in 16 (11.4%) patients. For the first time, genotype 5 was identified in the Western Province of Saudi Arabia. Genotype 1b and 4 were associated with different histological grades of liver disease.

Conclusion: Prevalence of osteopenia is higher than osteoporosis in the Saudi women above 40 years in the Northern part of Saudi Arabia. The major cause of low BMD is lack of exercise even though there is a high prevalence of Vitamin D deficiency. [Int J Res Med Sci 2014; 2(1.000: 274-278
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 When analyzing the impact of changes in oil and petroleum prices on Saudi Arabia’s economy the results indicate that adjustments in foreign savings, supporting an unchanged real exchange rate in the context of changes in oil world prices, quite effectively can insulate the domestic economy from international price fluctuations. If the economy is forced to adjust to the fall in world prices without offsetting changes in foreign savings, the resulting loss of export earnings and associated depreciation have major impacts on aggregate absorption, and the structure of production.

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.

These are: Desmometopa m-nigrum (Zetterstedt, 1848); D. varipalpis Malloch 1927; D. singaporensis Kertesz 1899; Leptometopa rufifrons Becker 1903; L. latipes (Meigen 1830); L. nilssoni Sabrosky, 1987; Milichia pubescens Becker 1907; Milichiella lacteipennis (Loew 1866); Enigmilichia dimorphica Deeming, 1981, from South-Western Saudi Arabia, the last seven species of the above are recorded for the first time. Biological information and distribution of these species are included. The fauna of Milichiidae found in this study is much more of Afrotropical than Palaearctic origin. (author)
Full Text Available A sample of 50 wives and 50 husbands from Saudi Arabia completed a battery of scales assessing different aspects of couple relationship functioning which had been translated from English to Arabic. The selection of measures was based on the Vulnerability-Stress-Adaptation Model (VSA, Karney & Bradbury, 1995 and included measures of partner attachment, conflict behaviour, and relationship with members of the family-in-law as predictors and marital satisfaction as criterion variable. All scales of the test battery showed acceptable reliability. The newly developed conflict behaviour scale consisted of three theoretically meaningful factors (Positive behaviour, Negative behaviour, and Abuse. All instruments showed evidence for convergent validity and contributed significantly to the prediction of relationship satisfaction. The results showed in general a similar pattern of correlations in Saudi Arabia as previous studies in Western countries.

Alkhurma hemorrhagic fever virus (genus Flavivirus, AHFV) was recently identified as the agent of a viral hemorrhagic fever in Saudi Arabia and characterized serologically and genetically as a variant genotype of Kyasanur Forest disease virus (KFDV). Since viral diagnosis and vaccine development may be hindered by genetic diversity, this study was intended to address AHFV genetic heterogeneity. Eleven strains isolated from hospitalized patients from 1994 to 1999 in Saudi Arabia were sequenced in the envelope, NS3, and NS5 genes. Homologous sequences were compared and used to look for patterns reflecting specific evolution associated with spatiality, temporality, infection pathway, and disease prognosis. Genetic analyses showed low diversity, which suggests a slow microevolution. Evaluation of divergence times showed that AHFV and KFDV ancestral lineage diverged 66-177 years ago, and the diversity observed within the studied AHFV strains reflected a 4- to 72-year period of evolution.

The geographical distribution of Alpha and Beta-Thalassemias differ markedly. Alpha-Thalassemia being particularly prevalent in Southeast Asia and Beta-Thalassemia in the Mediterranean basin. Thalassemia syndromes are common in Saudi Arabia: the Beta-Thalassemia genes occur with variable frequency in different regions of Saudi Arabia and both B+ and Bo thalassemia have been reported. Alpha-Thalassemia is also highly prevalent here and the interaction with the sickle cell gene is commonly observed. Over the last few years, a great deal of information regarding the clinical, molecular and management of these disorders has accumulated in the literature. In this paper we summarize some of the recent studies on the subject along with our experience and our attempt to highlight a number of questions still awaiting answers.

Saudi Arabia is the third-largest per capita water user worldwide and has addressed the disparity between its renewable water resources and domestic demand primarily through desalination and the abstraction of non-renewable groundwater. This study evaluates the potential costs of this approach in the industrial and municipal sectors, exploring economic, energy, and environmental costs (including CO2 emissions and possible coastal impacts). Although the energy intensity of desalination is a global concern, it is particularly urgent to rethink water supply options in Saudi Arabia because the entirety of its natural gas production is consumed domestically, primarily in petrochemical and desalination plants. This burgeoning demand is necessitating the development of more expensive high-sulfur gas resources that could make desalination even pricier. The evolving necessity to conserve non-renewable water and energy resources and mitigate GHG emissions in the region also requires policy makers to weigh in much more considerably the energy and environmental costs of desalination. This paper suggests that in Saudi Arabia, the implementation of increased water conservation and reuse across the oil and natural gas sectors could conserve up to 29% of total industrial water withdrawals at costs recovered over 0-30 years, depending on the specific improvement. This work also indicates that increasing wastewater treatment and reuse in six high-altitude inland cities could save a further $225 million (2009 dollars) and conserve 2% of Saudi Arabia's annual electricity consumption. By these estimates, some anticipated investments in desalination projects could be deferred by improving water efficiency in industry and prioritizing investment in sewage and water distribution networks that would ensure more effective water reclamation and reuse. Simultaneously, such initiatives would conserve non-renewable natural gas resources and could help prevent the lock-in of potentially unnecessary desalination infrastructure that is likely to become more energy and cost efficient in future.

Full Text Available In this study, an endogenous investigation of the long run relationship between the demand for money, narrow definition of money (M1, and its determinants in Saudi Arabia was conducted. A structural break date was estimated by applying the Andrews (1993 and Andrews and Ploberger (1994 methods. These tests illustrated that there is evidence of a structural break for all of the variables, namely money demand, real income and nominal short-term interest rates when they are considered together. The results of the Hansen stability test support the idea that the instability of money demand could be related to the structural breaks. Since there is evidence of a structural break, the Gregory and Hansen procedure was used to test for the cointegrating equation of money demand. This test allows for a one time structural break in the relationship among the money demand variable, real income and nominal short-term interest rates. The results of this test affirm stable money demand in Saudi Arabia. The monetary aggregate in Saudi Arabia seems to be an appropriate indicator in the formulation of monetary policy.

Full Text Available Energy recovery from waste is not a new field of study, but its implementation continues to be a challenge in some Arab countries. Although there is abundance of useful waste in the urban markets, practices aiming at waste to energy conversion are still negligible. In the kingdom of Saudi Arabia, so-called green markets are abundant with renewable energy potential, but the practical implementation of this potential is missing. Therefore the objective of this paper is the evaluation of waste generation in KSA for the energy recovery purpose, and to show that the conversion of green waste into biofuel is not only environmentally friendly but also financially rewarding. Since the result illustrate that the major portion of the waste generated is organic waste, anaerobic digestion is proposed waste to energy technology because of its feasibility for biodegradation of moist organic wastes into biogas. Diversion of waste into biogas and bio-fertilizer will ensure that it is treated in such a way that it becomes a useful product instead of harmful one. Furthermore as the policy makers and planners in renewable energy sector have intended for kingdom of Saudi Arabia to be andquot;kingdom of sustainable energyandquot; as well, hence they are needed to give special attention toward the largest Saudi Arabia's green market and should invest more to implement this plan.

Dust event significantly influences surface radiation and energy balance, and also results in a variety of environmental problems. Saudi Arabia (16°-33°N, 34°- 56°E) is mainly covered by the Arabian Desert, and dust storm is a severe environmental problem in this region. Moderate Resolution Imaging Spectroradiometer (MODIS) observed aerosol optical depth (AOD), which has the newly developed satellite aerosol algorithm called "Deep Blue" integrated, were used to investigate the dust emissions in the research region during 2004-2009. In order to explore the reasons for dust emission variations, we analyzed the precipitation from the Global Precipitation Climatology Project (GPCP). Besides precipitations, dust emission is also associated with land surface conditions. Therefore, the influences of surface vegetation distribution and elevation on dust emissions were inspected with hyperresolution modeling, which integrated the MODIS Land Cover Type product into the Community Land Model version 4 (CLM4). Our main conclusions are: 1) during 2004-2009, most severe dust events happened in June and July, and centralized in southeastern Saudi Arabia; 2) the first and the second highest AOD values in each year were rising; 3) AOD seasonal mean was also increasing in boreal spring and summer; 4) these variations are associated with precipitation variations in Saudi Arabia; 5) dust emissions are sensitive to surface vegetation distributions, and reducing the areas covered by trees and grasslands results in increased dust emissions.

The demand for electricity in Saudi Arabia has grown rapidly, and a number of factors account for this growth. The aim of this paper is to estimate the level of this demand and test for its main determinants. Cross-sectional data (i.e. regional) spanning the period 1980-92 and several estimators are used to achieve reliable estimates of the short-run and long-run own-price and income elasticities. The findings seem to be quite reasonable. First, the fixed effects method seems to fit the data better. Secondly, both the sign and the size of virtually all the elasticity estimates lie within the plausible range and most of them are statistically significant at ten per cent. Overall, the empirical evidence suggests that the demand for electricity in Saudi Arabia is both price- and income-inelastic. However, the influence of urbanisation on electricity consumption is clearly larger than that of real income. Thirdly, the estimated speed of adjustment implies very short adjustment lags in the demand for electricity in Saudi Arabia. And finally, among the policy issues that are of relevance is the current pricing policy, which has been making the whole electricity sector suffer a loss
Background The epidemiology of Alkhurma hemorrhagic fever disease is yet to be fully understood since the virus was isolated in 1994 in the Kingdom of Saudi Arabia. Setting Preventive Medicine department, Ministry of Health, Kingdom of Saudi Arabia. Design Retrospective analysis of all laboratory confirmed cases of Alkhurma hemorrhagic fever disease collected through active and passive surveillance from 1st-January 2009 to December, 31, 2011. Results Alkhurma hemorrhagic fever (AHFV) disease increased from 59 cases in 2009 to 93 cases in 2011. Cases are being discovered outside of the region where it was initially diagnosed in Saudi Arabia. About a third of cases had no direct contact with animals or its products. Almost all cases had gastro-intestinal symptoms. Case fatality rate was less than 1%. Conclusions Findings in this study showed the mode of transmission of AHFV virus may not be limited to direct contact with animals or its products. Gastro-intestinal symptoms were not previously documented. Observed low case fatality rate contradicted earlier reports. Close monitoring of the epidemiology of AHFV is recommended to aid appropriate diagnosis. Housewives are advised to wear gloves when handling animals and animal products as a preventive measure.

This study aimed to determine the seroprevalence of Toxoplasma gondii in pregnant women in the south western region of Saudi Arabia and to find out the possible risk factors that may lead to infection. This cross sectional hospital based study was carried out at three hospitals in the south western region of Saudi Arabia from January 2008 to August 2010. Blood samples from 487 pregnant women were collected and used to detect anti-T. gondii antibodies IgM and IgG by enzyme linked immunosorbent assay (ELISA). A questionnaire interview was carried out to ask about some risk factors of infection. Among the 487 studied pregnant women, 38.8 % were seropositive for anti T. gondii IgG while 6.2 % were positive for anti T. gondii IgM and 3.3 % were positive for both anti T. gondii IgG & IgM. The only risk factor associated with seropositive anti T. gondii IgM was the history of the intake of immunosuppressive drugs. Regarding anti T. gondii IgG seropositivity, it was found to increase significantly with increased age, number of gravida and parities, and previous history of toxoplasmosis. The seroprevalence of T. gondii IgG & IgM by ELISA among pregnant women in the south western region of Saudi Arabia is considerable with few identifiable significant risk factors reported.

Saudi Arabia produces a majority of its fruits and vegetables locally in small-scale production farms. These farms utilize groundwater as the main source of irrigation water. The water-regulating authorities in Saudi Arabia rely on traditional culturing methods to monitor coliforms as indicators of microbial contamination. These methods are time-consuming, do not address the sources of contamination, and do not permit assessment on the associated health risk. To address these knowledge gaps, the study investigates the sources of contamination in eight wells northeast of Mecca, Saudi Arabia. The study focuses on the potential impact on groundwater quality due to a nearby chicken farm and urban runoffs from human residential areas. Besides performing conventional methods to determine nutrient content and to enumerate coliforms, quantitative PCR using four host-associated primer sets were used to distinguish microbial contamination from humans and livestock. High-throughput sequencing was also performed to determine the relative abundance of several genera associated with opportunistic pathogens. Bacterial isolates were cultivated from the vegetable samples harvested from these farms, and were characterized for their phylogenetic identities. Lastly, the study collates the information to perform quantitative microbial risk assessment due to ingesting antibiotic-resistant Listeria monocytogenes, Pseudomonas aeruginosa and Enterococcus faecalis in these vegetable samples.
Indoor radon concentration measurement in the dwellings of Al-Jauf region of Saudi Arabia was carried out using passive radon dosemeters. The objective of this radon survey was to obtain representative indoor radon data of Al-Jauf region. The study is a continuation of radon survey in main cities of Saudi Arabia which constitutes a baseline for Saudi Arabia in the Radon World Atlas. A total of 318 passive radon dosemeters were distributed randomly in the region and placed for a period of 1 y starting from April 2004 to April 2005. The results of indoor radon concentration measurement in 136 dwellings distributed in Al-Jauf region are presented. The remaining dosemeters were lost in the dwellings or mishandled. The results showed that the average, minimum, maximum radon concentrations and standard deviation were 35, 7, 168 and 30 Bq m-3, respectively. Geometric mean and geometric standard deviation of the radon distribution were found to be 28 and 1.83, respectively. (authors)
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.
Full Text Available This study examined the subject of the Saudi Arabian new vehicle market. The topic addressed involved thesales-cycle within the new vehicle purchase process in Saudi Arabia. The specific research problem identified abreak-down in the sales-cycle or, alternatively, a dysfunctional approach to the final step in the sales-cycle whichinvolves the post-purchase stage where the consumer typically makes referrals or recommendations to family,friends and colleagues regarding the product or service in question. In this case, the data collected for this studyin the form of an informal, anonymous survey of people that have purchased a new vehicle in the Saudi marketfound that the satisfaction rates with dealers were an abysmal 50 to 60% depending on the specific aspect ofservice quality addressed. The secondary data found that there are more than 700 thousand new vehicles sold inSaudi Arabia on average annually and this figure is expected to surpass one million in several years. Additionally,with the after sales market in service, parts and warranties continuing to expand to more than $1 billion, thispost-purchase process in the sales-cycle can no longer be ignored by new car dealerships in the market. Therecommendation is that new car dealerships develop and integrate social media into a customer loyalty programin the new car sales-cycle in order to improve customer satisfaction and referral rates.

The trends in the quality of biomedical education in pharmacy schools have witnessed significant changes in the 21st century. With the advent of continuous revision and standardization processes of medical curricula throughout the world, the focus has been on imparting quality education. This pedagogic paradigm has shifted to pharmacy schools. In Saudi Arabia, the concept of "medical and pharmacy education" is relatively new as mainstream pharmacy curriculum and universities were established only half a century ago. This period has seen major changes in the dimension of "pharmacy education" to keep pace with the education systems in the United States and Europe. As our knowledge and perceptions about pharmaceuticals change with time, this motivates educators to search for better teaching alternatives to the ever increasing number of enthusiastic and budding pharmacists. Recently, the academic system in Saudi Arabian Pharmacy has adopted a more clinically-oriented Pharm. D. curriculum. This paper deals with the major changes from the inception of a small pharmacy faculty in 1959, the College of Pharmacy at the King Saud University, Riyadh, to the model of progress and a prototype of pharmacy colleges in Saudi Arabia. The fifty year chronological array can be regarded as an epitome of progress in pharmacy education in Saudi Arabia from its traditional curriculum to the modern day Pharm. D. curriculum with a high population growth and expanding health care sector, the demand for qualified pharmacists is growing and is projected to grow considerably in the future. The number of pharmacy graduates is increasing each year by many folds and to meet the needs the system lays stress upon a constant revising and updating of the current curriculum from a global perspective.

Full Text Available Some 12.8 million in the age group 5–15 years are visually impaired from uncorrected or inadequately corrected refractive errors. In Saudi Arabia, the size of this public health problem is not well defined especially among primary schoolchildren. The purpose of this cross-sectional study was to assess the prevalence and pattern of refractive errors among primary school children in Al Hassa, Saudi Arabia. A total of 2246 Saudi primary school children aged 6 to 14 years of both genders were selected using multistage sampling method form 30 primary schools located in the three different areas of Al Hassa. School children were interviewed to collect demographics and vision data using a special data collection form followed by screening for refractive errors by trained optometrists within the school premises using a standardized protocol. Assessment of visual acuity and ocular motility evaluation were carried out and cover-uncover test was performed. Children detected with defective vision were referred for further examination employing subjective refraction with auto refractometer and objective refraction using streak retinoscopy after 1% cyclopentolate. Of the screened school children (N=2002, the overall prevalence of refractive errors was 13.7% (n=274, higher among females (Odds ratio, OR=1.39, P=0.012 and significantly more among students of rural residence (OR=2.40, P=0.001. The prevalence of refractive errors was disproportionately more among those aged 12-14 years (OR=9.02, P=0.001. Only 9.4% of students with poor vision were wore spectacles for correction. Myopia was the most commonly encountered refractive error among both genders (65.7% of the total errors encountered. Uncorrected refractive errors affected a sizable portion of primary school children in Al Hassa, Saudi Arabia. Primary schoolchildren especially females, rural and older children represents high risk group for refractive errors for which the included children were unaware.

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.

Passive acoustic monitoring has been successfully used on many elasmobranch species, but no such study has yet been published for the whale shark (Rhincodon typus). In some ways this is surprising as the known whale shark aggregation sites would seem to be ideal targets for this method. For this dissertation, two acoustic studies were carried out in Saudi Arabia and Tanzania. Each was performed in parallel with visual surveys and the Saudi population was also studied using satellite telemetry. Sighting and acoustic data were compared at both sites, and the results were mixed. The acoustic monitoring largely confirmed the results of visual surveys for the Saudi Arabian sharks, including seasonality, residency and a degree of parity and integration between the sexes that is unique to this site. Satellite tracks of tagged Saudi sharks were used to confirm that some animals migrated away from the aggregation site before returning in subsequent seasons, confirming philopatric behavior in this species. In contrast, the acoustic results in Tanzania demonstrated year-round residency of whale sharks in the area, despite seasonal declines in visually estimated abundance. Seasonal changes in habitat selection render the sharks at this site temporarily cryptic to visual sampling. The differing results are compelling because both the philopatric behavior demonstrated in Saudi Arabia and the cryptic residency of the Tanzanian sharks could explain the seasonal patterns in whale shark abundances reported at other aggregation sites. Despite their differences, both sites in this study can be classified as secondary whale shark nurseries and each may be a vital feeding ground for its respective population.
Full Text Available Mostafa A Abolfotouh, Abdallah A AdlanKing Abdullah International Medical Research Center, King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi ArabiaBackground: Informed consent is considered the most important step in clinical interventions. The aims of this study were (1 to assess the quality of informed consent for invasive procedures with regard to consent process and information given about risks and alternative treatments, and (2 to determine patients' attitude toward informed consent at King Abdulaziz Medical City, Riyadh, Saudi Arabia.Methods: A cross-sectional study was conducted of 162 adult patients in different wards after undergoing surgery or invasive procedures within 1–2 days of signing the informed consent, using a previously validated interview questionnaire. Data on patients' characteristics, type of invasive procedure, and some informed consent-related issues were collected. Multiple linear regression analysis was used to identify the predictors of the percentage mean score of quality of informed consent, and significance was considered at P ? 0.05.Results: The quality of informed consent was generally poor (% mean score = 50.98 ± 17.49. About two-thirds of patients were told during the informed consent process that they have to sign merely as routine, 48% thought that if they refused the treatment plan they would lose the interest of the treating physician to help them, 42% thought that by saying no they would lose the good relationship with their physician, and 42.6% were not interested in having a copy of the informed consent document. Significantly higher quality was predicted when the physicians were the ones who explained the informed consent (t = 4.15, P < 0.001 and when informed consent was explained to younger patients (t = 2.754, P = 0.007. The overall attitude of the patients toward the process of informed consent was satisfactory (% mean score = 76.31 ± 7.63.Conclusion: The results suggest either that patients are not aware of their rights or that physician paternalism is practiced in Saudi Arabia. Cultural barriers should not be an argument to diminish the role of informed consent. Further studies should focus on how the value of autonomy can be appreciated in the Saudi culture.Keywords: informed consent, quality, invasive procedure, Saudi Arabia
Full Text Available The objective of this study is to explore the knowledge, attitudes and intake of energy drinks among adolescents in Saudi Arabia. A multi-stage stratified sampling procedure was carried out to select 1061 school children aged 12–19 years, from Jeddah city, Saudi Arabia. A short self-reported questionnaire was administrated in order to collect the data. Of adolescents in the study, 45% drank energy drinks (71.3% males and 35.9% females; P<0.001. Advertisements were the main source of information on energy drinks (43%. The major reasons for consuming energy drinks were taste and flavour (58%, to ‘try them’ (51.9% and ‘to get energy’ (43%, albeit with significant differences between genders (P<0.001. About half of the adolescents did not know the ingredients of these drinks, and 49% did not know that they contain caffeine (P-values <0.006 and <0.001 between genders, respectively. The greater majority (67% considered energy drinks to be soft drinks. The study indicates the need for Saudi adolescents to be warned on the over-consumption of energy drinks. The study brings to attention the need for educational programmes related to increasing awareness in the community of the health effects related to high consumption of energy drinks.
Full Text Available Objectives: Unconventional therapy (UT is a therapeutic practice of alternative and complementary medicine that is not currently considered an integral part of modern medical practice. The aim of this article is to investigate the experience of Saudi patients with UT modalities in the treatment of asthma. Materials and Methods: We carried out a cross-sectional study of asthma patients referred to King Abdulaziz Medical City, Riyadh, Saudi Arabia, during the year 2004. Information was collected using a pre-designed questionnaire administered through interviews. Results: Two hundred consecutive patients with a mean age of 52.3 years (±18.7 were included in this study. Sixty-nine (34.5% of those patients used some form of UT in the previous year. There was a tendency to use UT among the older age group ( P = 0.029 and among those with longer duration of disease ( P = 0.009. However, there was no significant correlation observed between the use of UT and gender, FEV 1 , or disease control. The most commonly used form of UT was recitation of Holy Quran (9%, honey (24.5%, herbs (23.5%, cautery (12%, and blackseed (10%. There was no significant correlation between disease control and the use of modalities. Conclusion: Unconventional therapy is frequently practiced by asthma patients in Saudi Arabia, who commonly believe that UT will lead to improvement. The lack of evidence necessitates the fostering of a national project to address the practice of UT.

Full Text Available Background and Objectives: Despite its relatively low incidence in Saudi Arabia, breast cancer has been the most common cancer among Saudi females for the past 12 consecutive years. The objective of this study was to report the results of the first national public breast cancer screening program in Saudi Arabia. Methods: Women 40 years of age or older underwent breast cancer screening. Mammograms were scored using the Breast Imaging-Reporting and Data System (BI-RADS. Correlations between imaging findings, risk factors and pathological findings were analyzed. Results: Between September 2007 and April 2008, 1215 women were enrolled. The median age was 45 years, and median body mass index was 31.6 kg/m 2 . Sixteen cases of cancer were diagnosed. No cancer was diagnosed in 942 women with R1/R2 scores, and only 1 case of cancer was diagnosed in 228 women with R0/R3 scores. However, among 26 women with R4/R5 scores, 50% had malignant disease and 35% had benign lesions. No correlation was found between known risk factors and imaging score or cancer diagnosis. Conclusions: Public acceptance of the breast cancer screening program was encouraging. Longitudinal follow-up will help in better determining the risk factors relevant to our patient population.
Full Text Available Often referred as Government to Citizen (G2C e-government services, many governments around the world are developing and utilizing ICT technologies to provide information and services to their citizens. In Saudi Arabia (KSA e-government projects have been identified as one of the top government priority areas. However, the adoption of e-government is facing many challenges and barriers including technological, cultural, organizational which must be considered and treated carefully. This paper explores the key factors of user adoption of e-government services through empirical evidence gathered by survey of 460 Saudi citizens including IT department employees from different public sectors. Based on the analysis of data collected the researchers were able to identify some of the important barriers and challenges from these different perspectives. As a result, this study has generated a list of possible recommendations for the public sector and policy-makers to move towards successful adoption of e-government services in Saudi Arabia.

The extensive harrat lava province of Arabia formed during the past 30 million years in response to Red Sea rifting and mantle upwelling. The area was regarded as seismically quiet, but between April and June 2009 a swarm of more than 30,000 earthquakes struck one of the lava fields in the province, Harrat Lunayyir, northwest Saudi Arabia. Concerned that larger damaging earthquakes might occur, the Saudi Arabian government evacuated 40,000 people from the region. Here we use geologic, geodetic and seismic data to show that the earthquake swarm resulted from magmatic dyke intrusion. We document a surface fault rupture that is 8 km long with 91 cm of offset. Surface deformation is best modelled by the shallow intrusion of a north-west trending dyke that is about 10 km long. Seismic waves generated during the earthquakes exhibit overlapping very low- and high-frequency components. We interpret the low frequencies to represent intrusion of magma and the high frequencies to represent fracturing of the crystalline basement rocks. Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees. ?? 2010 Macmillan Publishers Limited.

More than 2000 Primary Healthcare Centers (PHCs) in Saudi Arabia refer the cases of patients who require additional healthcare services to general hospitals and specialized hospitals. Improving the method of communication between PHCs and the hospitals decreases the number of clinical visits to hospitals and improves patient care. The development of health information technology in Saudi Arabia over the last 5 years has improved the communication system between the primary healthcare and specialist physicians. The purpose of this case study is to report on the experiences of implementing the EHALA electronic referral system at a local Saudi hospital. The e-referral system "EHALA" was implemented in 2013 by the MOH in the central region as a unified health information system that connected almost 380 PHCs and more than 40 hospitals. The KSHCD was among the hospitals that benefited from the e-referral system. The hospital has advanced and improved communication with PHCs and hospitals in less than one year. Early findings suggest that the EHALA has streamlined and expedited the communication process for the PHCs and the hospital, which has improved the patient's continuity of care. However, several challenges remain such as lack of computer skills by staff, lack of interest in using EHALA, and lack of a clear change management strategy which is impacting the usability of the EHALA system.

Saudi Arabia covers a large portion of the Arabian plate, a region characterized by seismic activity, along complex divergent and convergent plate boundaries. In order to understand these plate boundaries it is essential to optimize the design of the broadband seismic station network to accurately locate earthquakes. In my study, I apply an optimization method to design the broadband station distribution in Saudi Arabia. This method is based on so called D-optimal planning criterion that optimizes the station distribution for locating the hypocenters of earthquakes. Two additional adjustments were implemented: to preferentially acquire direct and refracted wave, and to account for geometric spreading of seismic waves (and thus increases the signal to noise ratio). The method developed in this study for optimizing the geographical location of broadband stations uses the probability of earthquake occurrence and a 1-D velocity model of the region, and minimizes the ellipsoid volume of the earthquake location errors. The algorithm was applied to the current seismic network, operated by the Saudi Geologic Survey (SGS). Based on the results, I am able to make recommendations on, how to expand the existing network. Furthermore, I quantify the efficiency of our method by computing the standard error of epicenter and depth before and after adding the proposed stations.
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 The purpose of this research is to investigate the attractiveness factors influencing shoppers’ satisfaction, loyalty, and word of mouth in Saudi shopping mall centers. The independent variables were attractiveness factors represented by these variables namely aesthetic, convenience and accessibility, product variety, entertainment, and service quality. The dependent variables were shopper satisfaction, loyalty and WOM. A structured questionnaire was distributed to a sample of 600 shopping mall customers, representing all of the shopping malls shoppers in the city of Jeddah, Saudi Arabia. A purposive sampling technique was employed in this research. The multiple regression analysis showed the impact of shopping malls attractiveness factors on the shopper satisfaction. The attractiveness factors aesthetic, convenience and accessibility, product variety, entertainment, and service quality, had a positive effect on Saudi shopping mall shoppers’. The most significant factor was product variety. This research potentially contributes to shopping malls attractiveness factors and their impact on shoppers’ satisfaction in shopping malls of Saudi Arabia.

Full Text Available Background and Objectives: The prevalence of chronic obstructive pulmonary disease (COPD in Saudi Arabia is unknown. The aim of this study was to estimate the prevalence of COPD among smokers more than 40 years of age attending primary healthcare clinics in Saudi Arabia. Setting and Design: A questionnaire was used in a cross-sectional collection of demographic data and other items related to diagnosis of COPD in patients visiting primary healthcare clinics. Methods: Eligible subjects were current or ex-smokers and aged 40 years or above. Spirometry was performed according to American Thoracic Society criteria. Airflow obstruction was classified according to the 2003 update of the World Health Organization and Global Initiative for Chronic Obstructive Lung Disease criteria. COPD was defined as a ratio less than 0.70 of post-bronchodilator-predicted forced expiratory volume in the first second to forced vital capacity (FEV1/FVC <0.70. Results: Because of incomplete data or poor performance on spirometry, of 1380 subjects eligible for the study, only 501 subjects were eligible for data analysis. Seventy-one patients had an FEV1/FVC ratio <0.70, comprising 14.2% of the study population, of which 95.8% were males. Current smokers comprised 57 (80.3% subjects. Of the 71 subjects who fulfilled the criteria for COPD diagnosis, none were found to be in COPD stage I; 40 (56.3% were in stage II and 31 (43.6% were in stage III of the disease. Conclusion: Underdiagnosis of COPD in primary healthcare clinics in Saudi Arabia is common, but its extent is not different from the corresponding data available in the literature for other countries. Use of spirometry as a routine test for all patients older than 40 years of age and with a smoking history can help in early detection and proper diagnosis of COPD, which subsequently will help in implementation of preventive measures.

In the absence of permanent rivers or bodies of water, half of the Saudi Arabia domestic water consumption is provided through desalination. The other half is derived from groundwater. Groundwater from the Disi aquifer is already used for drinking water in parts of Jordan and, more extensively, in Saudi Arabia, where it is known as the Saq aquifer. Some of the geological analyses of the host sandstone aquifer rocks show 228Ra and 226Ra. The usefulness of chromosomal aberrations analysis as a bioindicator for ionising radiation effect was tested in underground water well workers of Saudi Arabia in this industry producing technologically enhanced naturally occurring radioactive material. The incidence of chromosomal aberrations was evaluated using the metaphase analysis method in the lymphocytes of peripheral blood of 10 persons working in underground water well. The age range of the workers was 25-40 y and their duration of service ranged from 3-7 y. For comparison, blood samples were also collected from 10 subjects (controls) who belonged to same age and socioeconomic status. Subjects in the both groups were non-smokers and non-alcoholics. Results showed that the mean frequencies of dicentrics and acentrics in underground water well workers are significantly higher than those in controls. The higher frequency of chromosomal aberration in lymphocytes of underground water well workers compared with controls could be due to the accumulative effect o could be due to the accumulative effect of radiation. The results of this study demonstrated that occupational exposure to radiation leads to a significant induction of cytogenetic damage in peripheral lymphocytes of workers engaged in underground water well.

Full Text Available HPV is closely associated with cervical cancer that the incidence of this tumor is regarded as a surrogate marker for HPV infection in countries lacking epidemiological studies. HPV is also implicated in subsets of anogenital and oro-pharyngeal cancers. Although cervical cancer is the third most common cancer in women worldwide, its reported incidence is low in Saudi Arabia, ranking number 12 between all cancers in females and accounts only for 2.4% of all new cases, despite the lack of national screening programs. However, the limited available studies from Saudi Arabia indicate that HPV prevalence and genotypes’ distribution in invasive cervical cancer show similar pattern as in the world. Cytology screening (Pap Smear and HPV vaccinations are the two preventive measures against cervical cancer. The two available vaccines are effective against the two most common HPV genotypes (HPV-16 and 18. Since 92% of cervical tumors in the Kingdom are infected with HPV of which 78% are HPV-16 and 18 genotypes, vaccination is expected to protect against more than two-third of cervical cancers in Saudi Arabia. Nevertheless, due to its low incidence (2.1/100,000 women, a proper cost-effectiveness analysis is required to justify the implementation of a costly vaccine bearing in mind that HPV could potentially be associated with about 3% of all cancers. However, further studies are needed to ascertain the real prevalence of HPV at the population level at large, its association with various types of cancers and also the impact of local tradition and emerging behavioral trends that could affect HPV transmission and consequently the effectiveness of applying national vaccination program.
A model for the emission of PM 10 dust has been constructed using the concept of a threshold friction velocity which is dependent on surface roughness. Surface roughness in turn was correlated with geomorphology or soil properties for Kuwait, Iraq, part of Syria, Saudi Arabia, the United Arab Emirates and Oman. The PM 10 emission algorithm was incorporated into a Lagrangian transport and dispersion model. PM 10 air concentrations were computed from August 1990 through August 1991. The model predicted about the right number of dust events over Kuwait (events occur 18% of the time). The model results agreed quantitatively with measurements at four locations in Saudi Arabia and one in Kuwait for one major dust event (>1000 ?g/m 3). However, for smaller scale dust events (200-1000 ?g/m 3), especially at the coastal sampling locations, the model substantially over-predicted the air concentrations. Part of the over-prediction was attributed to the entrainment of dust-free air by the sea breeze, a flow feature not represented by the large-scale gridded meteorological data fields used in the model computation. Another part of the over-prediction was the model's strong sensitivity to threshold friction velocity and the surface soil texture coefficient (the soil emission factor), and the difficulty in accurately representing these parameters in the model. A comparison of the model predicted PM 10 spatial pattern with the TOMS satellite aerosol index (AI) yielded a spatial pattern covering a major portion of Saudi Arabia that was quite similar to the observed AI pattern.

Saudi Arabia occupies most of the Arabian Peninsula and has an area of 872,722 sq miles, or 2,260,350 sq km. The ancient Arabian Shield of igneous and metamorphic rocks comprises most of the western third of the country. The shield contains many extinct volcanoes surrounded by lava beds. Sloping eastwards are the newer sedimentary areas in which rich oil fields are found. In Saudi Arabia oil is paramount and less effort has been put into searching for mineral deposits than in other countries of similar size and geology. Pour aerial radiometric surveys have been undertaken and some of the anomalies discovered in the earlier ones were ground checked by an IAEA expert in 1963-64. Two anomalies warranted more detailed work, these were the Jabal Said anomaly in the Central Shield area and the Al Ghrayyat in Wadi Sawawin about 70 miles from the Jordan border. The Jabal Said anomaly consists of a zone of altered rocks consisting largely of pegmatite and pegmatite granite= Allanite, pyrochlore, cyrtolite, xenotime and monazite are the ore minerals,, The deposit was estimated to have 2.2 million tons of ore grading 0.2 - 0.3 percent Nb2O5 and 0.03 - 0,05% U3O8. The other occurrence at Al Ghrayyat is similar but with much lower grade uranium content. In view of the huge size of Saudi Arabia, the existence of many geologically favourable rock types and the poor coverage by sophisticated uranium exploration techniques, the Speculative Potential is placed between 10,000 and 50,000 Tonnes uranium.

Four main phases of the history of Saudi-Arabian mineral oil politics are described, each of which marks one stage on the way to full oil-related sovereignty of the kingdom: 1. finding concession-holders for mineral oil, 2. Cooperation with ARAMCO in order to build up the country's mineral oil industry, 3. Cooperation with other OPEC-states in nationalising the oil industries, 4. participation in the 2nd Gulf War in order to achieve full sovereignty in matters of energy politics. Special attention is given to the specifically Saudian connection of foreign - and oil politics and the importance of historical ''coincidences'' for the success of Saudi Arabia's type of mineral oil politics.

Full Text Available The objective of this study is to determine the perception of retail service quality and its relationship withsatisfaction for customers of hypermarkets in the Kingdom of Saudi Arabia (KSA. Data was collected throughself-administered questionnaires using convenience sampling technique. Out of 220 responses, 185 were finallychosen and analyzed for descriptive statistics as well as significant relationship between hypermarket servicequality and customer satisfaction. The respondents reported high levels of perceived quality and significantrelationship was found between retail service quality dimensions and customer satisfaction. Out of all thedimensions of service quality, physical aspects had the maximum effect on customer satisfaction, which wasattributed to the cultural traits and lifestyle of Saudi society. Retail service providers need to recognize theimportance of service quality dimensions in order of their significance, and implement appropriate strategy forcompetitive advantage over domestic and international players vying for share of an expanding consumer base.
Diminishing groundwater resources and a growing need of water in arid countries like the Kingdom of Saudi Arabia necessitate increased reuse of treated wastewater. Therefore a characterization study was carried out to determine the seasonal variations in the quality of secondary effluent for agricultural purposes produce from the AI-Khobar wastewater treatment plant. All the basic parameters such as chlorides, TSS, TDS, BOD, pH, turbidity total coliform including metals, nutrients, and oil and grease were studied. A comparison between the treated wastewater quality from the AI-Khobar and other Gulf region WWTPs was also made. Moreover the secondary effluent quality was also compared with the Saudi Presidency of Meteorology and Environment (PME) discharge standards and the Ministry of Agriculture (MA) irrigation standards. Results showed seasonal variations in the effluent quality. Based on the methodology used in the present study suggestions have been given to improve the wastewater quality and application areas in the field of agriculture. (author)

Over the past couple of years, the frequency and magnitude of flash floods are increasing in the Kingdom of Saudi Arabia. For effective planning and mitigation purposes, it is necessary to identify and visualize areas that are vulnerable to the flooding. In this paper, we will first create a flash flood social and physical vulnerability index for the city of Riyadh based on physical and social-economic data. Building upon the index, the areas of Riyadh that are highly vulnerable to flash floods will be identified and mapped using Geographic Information Systems (GIS). Finally, possible mitigation measures that can be used to reduce the impacts of flooding will be discussed in details.

The aims of this study were to assess QoL in patients with skin diseases in central Saudi Arabia using the newly validated Skindex-16 instrument and to determine the association between QoL in patients with skin disease, sociodemographic data, and disease characteristics.Methods: A cross-sectional study was conducted in 283 adult patients who visited the outpatient dermatology clinics of King Abdulaziz Medical City, Riyadh, Saudi Arabia, over 3 months. The patients were interviewed using a pretested Arabic version of the Skindex-16 to measure the effect of skin disorders on their QoL during the previous 7 days. Patient characteristics, medical history, and clinical findings were collected. Multiple linear regression analyses were used to relate the demographic and clinical characteristics to the percentage mean QoL score, and P # 0.05 was considered to be statistically significant.Results: QoL was good in 69% of the respondents, with a total percent mean score of 31.80 ± 20.16. The emotional domain was the most affected (mean percentage score 44.27 ± 27.06, followed by symptoms (31.45 ± 28.40 and functioning (14.61 ± 22.75. After adjustment for potential confounders, poorer QoL was significantly associated with female gender (P = 0.03, older age (P = 0.003, rural origin (P = 0.03, positive family history of the same lesion(s (P = 0.01, shorter duration of ? 6 months (P = 0.02, generalized spread (P ? 0.02, and lack of isotretinoin treatment (P = 0.02.Conclusion: The QoL results in this study were generally more optimistic than those of many previous studies. This discrepancy may be due to biases in questionnaire responses or to cultural differences in experience of skin disease and perception of disability. Significant predictors of QoL were not the same for the three domains of the Skindex scale. Further studies of specific diseases and educational programs targeting patients at higher risk for QoL impairments are recommended.Keywords: quality of life, skin disease, Saudi Arabia

There is no doubt that the laboratory is the backbone for the diagnosis of tuberculosis (TB. Only through testing in the laboratory can the physician confirm suspicion of TB despite any previous clinical and x-ray findings. Recent visits to several laboratories in the Kingdom of Saudi Arabia showed that some need considerable improvement. Unless there are standardized procedures to diagnose TB, and safety measures are implemented in all laboratories, it will be impossible to diagnose accurately and control TB. The laboratories should be redesigned to conform to international TB Diagnostic Centers, with well trained staff and proper safety procedures.

Full Text Available The occurrence of atopic diathesis in hereditary ichthyosis (HI has not been documented in Saudi patients. The atopic manifestations in histopathologically confirmed HI patients attending the dermatology clinic of king Fahad Hospital of the University at Al-Khobar city, Saudi Arabia is discussed in this study. From the dermatology OPD logbook, all Saudi patients with confirmed HI seen between January 1990 to December 1995 were included in the study. The findings regarding atopic manifestations were extracted into data collection forms and analyzed. During the 5 year study period, 10,455 new cases were seen in our dermatology OPD. Of these, 61 had hereditary icthyosis, with 37 males and 24 females with a male to female ratio of 1.5:1. Thus, the frequency of HI among Saudi hospital attendees was 6 per 1000 new cases. The type of HI was ichthyosis vulgaris in 25 (41% patients, X-linked recessive ichthyosis in 11 (18%, lamellar ichthyosis in 4(7%, bullous ichthyosiform erythroderma in 2 (3% and nonbullous ichthyosiform erythroderma was seen in 19 (31%. Generalized pruritus was present in 49 (80% cases, atopic dermatitis in , elevated serum IgE level was noted in 27 and bronchial asthma in 3 cases. Dandruff was reported in 24 cases, keratosis pilaris in15, recurrent skin infection in 7. Combination of hereditary ichthyosis, generalized pruritus and high serum IGE level was reported in 27 (44.3% patient.

Full Text Available Background : Helicobacter pylori (H. pylori is an important pathogen in gastrointestinal disorders. Seroprevalence among asymptomatic and chronically diseased children in Jeddah, Saudi Arabia was determined to gain insight into its prevalence. Methods : Serum samples obtained from 1432 children; 543 asymptomatic and 889 chronically diseased children (diabetes, chronic asthma, chronic hemolytic anemia, neurological impairment and Down?s syndrome; were tested by ELIZA for H. pylori IgG antibodies. Demographic data obtained including nationality, gender, age and disease status. Results : One hundred and twenty eight (23.6% of 543 asympatomatic children were seropositive with no significant difference in seroprevalence of infection between Saudi and non-Saudi (p< 0.09 and between boys and girls (p< 0.67, but significant rise was notice with increasing age (p< 0.001. An increase in risk of H. pylori among chronically diseased children was observed (diabetes: 34.4%, chronic asthma 20.4%, chronic hemolytic anemia: 31.7%, neurological impairment: 32.1%, and Down?s syndrome: 29.2% which increased significantly in chronic anemia and neurological impairment (p< 0.01 and p< 0.05 compared to controls. The prevalence did not differ according to nationality and gender but significantly increased with age in chronic asthma, chronic anemia and neurological impairment (p< 0.01 for all and also increased significantly with duration of illness, number of blood transfusions, number of hospital admission and mode of feeding. Conclusion : Infection with H. pylori seems to occur early in life and its prevalence increased with age in Jeddah, Saudi Arabia. The risk of H. pylori infection was significantly increased within children suffering from chronic hemolytic anemia; neurological impairment compared to controls and was significantly related to severity of the chronic disease.

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 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.

Ertaa (Calligonum comosum) and Ghada (Haloxylon persicum) are two important multipurpose indigenous shrubs in the desert of Saudi Arabia, supplying firewood and fodder to the local populations. Their environmental benefits in connection with sand dune fixation and microenvironment improvement are commendable. Due to over-exploitation and habitat destruction, populations of these two shrubs have become severely degraded. This study helps in the development of the appropriate techniques for their regeneration and evaluates their relative growth rate under different irrigation schedules. Productivity in the natural population and biolo
