The National Commission for Wildlife Conservation and Development (NCWCD) was established in 1406 (H), and enacted plans to control grazing, wood gathering and hunting in the protected areas of Saudi Arabia. However, its efforts have not been successful in putting an end to uncontrolled grazing, trees felling and hunting in the protected areas. This is mainly due to the non-enforcement of the ban on hunting which is considered a local tradition, the freedom of trade in allowed and non-allowed animals, and people low level of awareness about the rules and regulations of hunting, grazing and trees felling. The aim of this study is to determine the level of knowledge, attitudes and people's behaviors towards the Ibex reserve, to recommend solutions that can put an end to illegal hunting, and to show the role of education programs in solving this problem. The study population consisted of all people residing around the Ibex reserve, in the towns of Haotat Bany Tammem , Al-Helwa and Al-Hareek. A simple random sample of 400 people was taken. The response rate was 86%. Furthermore, more than 25 focus group discussion sessions took place, in which the researcher met with 240 local people. Percentages, means, standard deviations and simple correlation were used to analyze the study data using the Statistical Package for Social Sciences (SPSS). The study indicated that the young generation's level of knowledge regarding the importance of wildlife is low. The main reason for this is the lack of educational programs that deals with the importance of wildlife conservation. The study also showed that the respondents have good information about the Ibex reserve location and the patrolling system used to protect it, while their information about the plants and animals' life in the reserve is limited. The respondents perceived that the enforcement of punishment is the only way to put an end to illegal hunting in the reserve. It is recommended to have television educational programs

No previous study has provided a detailed description of regional variations of growth within the various regions of Saudi Arabia. Thus, we sought to demonstrate differences in growth of children and adolescents in different regions. The 2005 Saudi reference was based on a cross-sectional representative sample of the Saudi population of healthy children and adolescents from birth to 18 years of age. Body measurements of the length, stature, weight, head circumference and calculation of the BMI were performed according to standard recommendations. Percentile construction and smoothing were performed using the LMS (lambda, mu and sigma) methodology, followed by transformation of all individual measurements into standard deviation scores. Factors such as weight for age, height for age, weight for height, and head circumference for children from birth to 3 years, stature for age, head circumference and body mass index for children between 2-18 years of age were assessed. Subsequently, variations in growth between the three main regions in the north, southwest, and center of Saudi Arabia were calculated, with the Bonferroni: method used to assess the significance of differences between regions. There were significant differences in growth between regions that varied according to age, gender, growth parameter and region. The highest variation was found between children and adolescents of the southwestern region and those of the other two regions The regression lines for all growth parameters in children <3 years of age were significantly different from one region to another reaching - 0.65 standard deviation scores for the southwestern regions ( P =.001). However, the difference between the northern and central regions were not significant for the head circumference and for weight for length. For older children and adolescents a significant difference was found in all parameters except between the northern and central regions in BMI in girls and head circumference in

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 Adeloye-Odeku disease, also known as congenital inclusion dermoid cyst (CIDC of the anterior fontanelle was first described by Adeloye A and Odeku EL, as a solitary congenital subgaleal inclusion dermoid cyst of the anterior fontanelle. This rare lesion was initially thought to be confined to Africans . The universal distribution of this cyst has subsequently been shown in accumulated literature of other ethnic distribution ,Caucasian, Indians, Chinese, Japanese, Turkish and others. This is the first published report that we know of Adeloye-Odeku disease in Arab-Saudi children in Abha, Saudi Arabia. Four patients with Adeloye-Odeku disease, two boys and two girls, Saudi patients with ages ranging from 3months to 9 years are presented. Successful surgical excision of the cyst was achieved in each of the three patients who consented for surgery with no recurrence. The oldest patient did not go for surgery due to parental refusal but the lesion proved to be stable on follow up.
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.

Saudi Arabia is the largest country of the Arabian Peninsula, blessed with significant natural resources, including oil, gas and minerals. Saudi Arabia has recognised the importance of education in social and economic transformation, and has established a large number of universities, research and advanced technical institutes which have broken the metropolitan boundaries and have been extended to the far-flung areas of the country. There are 68 universities and degree-awarding institutes. The educational budget reached its highest-ever level of $56.56 billion for the year 2014. About 124,000 Saudi students are pursuing higher education in about 500 universities around the world. Saudi Arabia produced 177826 research papers in Institute for Scientific Information (ISI) database and in the year 2014 alone, 26168 research papers were published in indexed science journals with a rising h-index of 144. The country is turning into a regional hub for advanced education, research, science and technology while swiftly shifting from an oil-based to a knowledge-based economy. PMID:26440844

This study aimed to provide recent data on the occurrence of non-strongyle intestinal parasite infestation in horses in the Riyadh region of Saudi Arabia as a basis for developing parasite control strategies. We conducted necropsy for 45 horses from September 2006 to November 2007 in the Riyadh region, Saudi Arabia. 39 out of 45 horses were infected with intestinal parasites with an infestation rate of 86.6%. Infestations with seven nematode species and two species of Gasterophilus larva were found. The most prevalent parasites were Strongyloides westeri (64.4%) and Parascaris equorum (28.8%) followed by Habronema muscae (22.2%). Trichostrongylus axei and Oxyuris equi were less common at (11.1%) and (8.8%), respectively. Habronema megastoma and Setaria equine were found in two horses only (4.4%). Gasterophilus intestinalis larvae were recovered from 39 horses (86.6%) and Gasterophilus nasalis larvae were found in 17 horses (37.7%). Season had a significant effect on the prevalence of P. equorum and G. nasalis, while age of horses had a significant effect only on the prevalence of P. equorum. The husbandry in Saudi Arabia appears to be conductive to parasites transmitted in stables or by insects rather than in pasture. PMID:23961139

Full Text Available Introduction: Hypertension (HTN is a common health problem in Saudi Arabia. Good control depends on the quality of care, which should be supervised and monitored regularly through clinical audit. Aims: The objective of this study was to assess the quality of HTN care at Al-Manhal Family Practice, Aseer Region, Saudi Arabia. Settings and Design: This study was conductedin 2009 at Al-Manhal Family Practice, Aseer Region, Saudi Arabia. Materials and Methods: Medical records of all hypertensive patients were extracted and reviewed using master sheets. Assessment of processes and outcomes of HTN care were based on the standards of quality assurance manual issuedby the Ministry of Health. Statistical Analysis Used: Data were entered and analyzed by SPPS, version 15. Relevant statistical tests were used accordingly and the P-value was considered significant when it was less than 0.05. Results: A total of 295 medical records were reviewed and assessed. Most patients were Saudi, married, and about 50% were educated. Two-hundred and thirty-one records were assessed for processes and outcomes of HTN care. Weight measurement and physical examination were carried out for 99% and 97% of the patients, respectively. For 53% of the patients, blood was checked for glucose and kidney function and a lipid profile was done. More than two-thirds of the patients were overweight and obese while 46% had diabetes. Less than one half of the patients had good control of HTN. Conclusions: By most standards, quality of HTN care in Al-Manhal Family Practice was unsatisfactory. Most of the patients had comorbidities and poor HTN control. Essential facilities should be provided to the practice to optimize HTN care and to improve the degree of control.

Full Text Available Abstract Background Human origins and migration models proposing the Horn of Africa as a prehistoric exit route to Asia have stimulated molecular genetic studies in the region using uniparental loci. However, from a Y-chromosome perspective, Saudi Arabia, the largest country of the region, has not yet been surveyed. To address this gap, a sample of 157 Saudi males was analyzed at high resolution using 67 Y-chromosome binary markers. In addition, haplotypic diversity for its most prominent J1-M267 lineage was estimated using a set of 17 Y-specific STR loci. Results Saudi Arabia differentiates from other Arabian Peninsula countries by a higher presence of J2-M172 lineages. It is significantly different from Yemen mainly due to a comparative reduction of sub-Saharan Africa E1-M123 and Levantine J1-M267 male lineages. Around 14% of the Saudi Arabia Y-chromosome pool is typical of African biogeographic ancestry, 17% arrived to the area from the East across Iran, while the remainder 69% could be considered of direct or indirect Levantine ascription. Interestingly, basal E-M96* (n = 2 and J-M304* (n = 3 lineages have been detected, for the first time, in the Arabian Peninsula. Coalescence time for the most prominent J1-M267 haplogroup in Saudi Arabia (11.6 ± 1.9 ky is similar to that obtained previously for Yemen (11.3 ± 2 but significantly older that those estimated for Qatar (7.3 ± 1.8 and UAE (6.8 ± 1.5. Conclusion The Y-chromosome genetic structure of the Arabian Peninsula seems to be mainly modulated by geography. The data confirm that this area has mainly been a recipient of gene flow from its African and Asian surrounding areas, probably mainly since the last Glacial maximum onwards. Although rare deep rooting lineages for Y-chromosome haplogroups E and J have been detected, the presence of more basal clades supportive of the southern exit route of modern humans to Eurasian, were not found.

Diagnostic reference levels (DRLs) are an important optimisation tool, which aid in identifying abnormally high dose levels. These are currently not available in Saudi Arabia, and this research aims to remedy this. CT dose data (DLP and CTDIvol) were collected for a minimum number of 10 adult patients of average size (60-80 kg) presenting for a range of CT examinations from public hospitals in the western region of Saudi Arabia. These include routine chest, high-resolution chest (HRCT), pulmonary angiography (CTPA), abdomen and pelvis (AP) and the combined chest, abdomen and pelvis (CAP) CT examinations. Mean values for each site were calculated, and the 75. percentile of DLP and CTDIvol was used as a basis for DRLs. Data for 550 patients were collected from 14 hospitals over a 7-month period. The rounded third-quartile CTDIvol and DLP were 18 mGy and 630 mGy cm-1 for chest CT, 20 mGy and 600 mGy cm-1 for HRCT, 18 mGy and 480 mGy cm-1 for CTPA, 15 mGy and 800 mGy cm-1 for AP, and 16 mGy and 1040 mGy cm-1 for CAP, respectively. Regional DRLs have been proposed from this study. Dose variations across CT departments have identified an urgent need for optimisation to improve distribution of observed doses for CT examinations.

Full Text Available Abscess disease (caseous lymphadenitis and Morel disease is a worldwide contagious bacterial disease of sheep and goats and is adversely affecting the development of the sheep industry in Saudi Arabia. Fifteen sheep and 12 goat farms at Qassim region, central Saudi Arabia, were surveyed during September and October 2008 for the determination of the prevalence and the etiology of abscess disease. One hundred and twenty pus samples were collected from affected external lymph nodes of clinically-ill sheep and goats and from infected internal lymph nodes and organs condemned during meat inspection in the slaughterhouses, for the isolation and identification of pathogenic bacteria causing sheep abscess disease. The prevalence of abscess disease varied between 5%– 44.1% in sheep farms, being highest in the Najdi breed, and between 2.2 % – 6.5 % in goat farms. Males of both sheep and goats had the highest rate of infection compared to females (p <0.01. Bacterial isolates were obtained from 97 out of the 120 collected pus samples (80.83%. The remaining 23 samples were sterile. Corynebacterium pseudotuberculosis and Staphylococcus aureus subsp. anaerobius accounted for about 54% of isolates, with almost equal frequencies (p =0.5. Other pyogenic bacteria such as S. aureus, Streptococci, Pseudomonas aeruginosa, Actinomyces pyogenes were also isolated from infected abscesses. They represented about 46% of the isolated etiological agents of sheep abscesses. This explains why available vaccines (bactrins against caseous lymphadenitis (CLA are poorly protective against abscess disease in Saudi Arabia. [Vet. World 2011; 4(11.000: 495-499
The Al-Qatif region in the Eastern Province of Saudi Arabia has thehighest prevalence of alpha-thalassemia genes in the Kingdom. Hemoglobin H(Hb H) disease, however, has been rarely reported. We decided therefore toverify the rarity of disease and characterize the presenting features incases identified. All patients seen in Qatif Central Hospital betweenSeptember 1988 and November 1990 with low red cell indices were screened forHb H disease and those found positive had clinical data compiled from theirhospital records and analyzed. Thirty-nine cases of Hb H were diagnosed. Themean age of patients was 18 years. The mean hemoglobin was 13.5 g/dL forneonates and 7.6 g/dL for others. The mean Hb Bart's level was 27.5% inneonates and the mean Hb H level in others was 11.1%. In addition to low redcell indices, all patients had a high red cell distribution width (RDW) meanof 25.6%. The main clinical signs were jaundice and hepatosplenomegaly.Concurrent glucose-6-phosphate Dehydrogenase (G6PD) deficiency was seen in28.2% of patients. Hemoglobin H disease is not uncommon in the Al-Qatifregion of Saudi Arabia. The red cell indices may mimic iron deficiency, whichshould be excluded by the presence of jaundice and organomegaly. Thecondition often co-exists with G6PD deficiency. (author)
Amaranthus pollen grains are known to have highly allergenic and potential cause of respiratory allergic diseases. Nevertheless, data on the prevalence of Amaranthus pollen in the environment is limited and almost non-existent for Saudi Arabia. We conducted an investigation to record the airborne incidence of A.viridis and other allergenic pollen in Al-Khobar, Dammam, Hail, Jeddah, Jizan, Qassim and Taif, using Burkard Volumetric Samplers. The samples were operated continuously for one year at each location. The data revealed A.viridis as one of the major components of outdoor airspora, constituting a maximum of 96% of total pollen counts in Hail, followed by Al-Khobar (89%), Jeddah (87%), Qassim (85%), Taif (84%), Dammam (83%) and Jizan (61%). These higher percentages contributed largely to the total weed pollen catch during August to November in all seven regions. In addition, the data also showed that A. virdis pollen were present throughout the year with distinct seasonal variations. The diel periodicities for at least five sites averaged over a year showed mid-day to early evening maxima. The maximum concentration approached 3000 mt. cube of air in October and 1827 mt. cube of air in September. The data also exhibited, a seasonal pattern, in their maximum appearance. Further studies related to biochemical and allergological aspects are needed to confirm the allergenic impact of Amaranthus pollen and sensitization in allergic individuals in the Kingdom of Saudi Arabia.

Full Text Available Purpose: No study had been conducted to assess the hospitals’ environment for learning purposes in multicenter sites in Saudi Arabia. It aims to evaluate the environment of hospitals for learning purposes of pediatric residents. Methods: We applied Postgraduate Hospital Educational Environment Measure (PHEEM to measure the learning environment at six teaching hospitals in the Eastern Region of Saudi Arabia from September to December 2013. Results: The number of respondents was 104 (86.7% out of 120 residents and 37 females and 67 male residents have responded. The residents’ response scored 100 out of 160 maximum score in rating of PHEEM that showed overall learning environment is favorable for training. There were some items in the social support domain suggesting improvements. There was no significant difference between male and female residents. There was a difference among the participant teaching hospitals (p<0.05. Conclusion: The result pointed an overall positive rating. Individual item scores suggested that their social life during residency could be uninspiring. They have the low satisfactory level and they feel racism, and sexual discrimination. Therefore, there is still a room for improvement.
Full Text Available Background. Khat chewing is highly prevalent in Africa, Yemen and Jazan region, southwest of Saudi Arabia. Most of Jazani Khat chewers consider khat session as a social activity and do not consider khat dependency. The aim of this study was to explore khat dependency and its relationship with the psychophysical symptoms among chewers. Methods. Cross-sectional study on seventy Saudi male khat chewers living in Jazan area. Psychological dependence to khat chewing was evaluated using the Severity of Dependency Scale (SDS. The participants filled in a self-administrated assisted structured questionnaire designed to collect data about their medical history, neurological symptoms, and their chewing behavior. Results. Half (52.2% of khat chewers showed psychological dependency. Those having longer khat sessions (≥6 hours were more liable for dependency. Physical and psychological symptoms were more prevalent among khat dependent chewers. Conclusions. khat has a psychological dependence effect that can be measured by the SDS, even in low doses and with irregular use. SDS scale is a useful tool to expect the burden of either physical or psychological symptoms on khat chewers.
Wheat is one of the most grown crops in Saudi Arabia. It is grown in various regions of the country. Accurate knowledge of the elemental concentrations in wheat and its products (bran and flour) is of great importance from a nutritional point of view.

Few studies evaluated injection safety practices in Saudi Arabia.Objective: To examine the structure and process of injection safety at primary health care level in Jazan health district, to evaluate knowledge, attitudes, and practices of primary health care physicians and nurses towards injection safety, and to determine the incidence of needle stick injuries among health care workers in Jazan region, Saudi Arabia.Methods: A cross-sectional study was conducted in Jazan primary health care centers (PHCCs, Saudi Arabia from September 2011 to March 2012. Data were collected using an observational checklist and data collection sheet. Jazan city health district was chosen at random from the 14 health sectors in Jazan region. All the 33 (10 urban, and 23 rural PHCCs of Jazan city were included in this study to get the predetermined sample size of health care workers. 200 health care workers (HCWs were recruited (29% physicians, and 71% nurses.Results: Syringes in the PHCCs were disposable (100%, individually packed (92%, and available at all volumes (98%. Methods of safe disposal of needles and sharps were also operated through contracting with professional companies in 84.8% of instances. Urban PHCCs had more posts for injection safety promotion than rural centers (p=0.02. Continuous Medical Education (CME programs on infection control were present in only 60% of PHCCs. At least 95% of HCWs in Jazan believed that sharp objects should be kept in a puncture-proof container, kept in a closed container, or disposed by a professional company. More than 80% of HCWs washed their hands by soap and water and cleaned them by alcohol before giving injection, and also got the three doses of hepatitis B vaccine.The rate of needle stick injury in the past year was 14%, without a significant difference between

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

Since the Physicians start use of antibiotics long ago with un-notice drug resistance. However actual problem was recognized about 85 years ago. Antibiotic resistant and Multi-drug resistant bacterial strains are at rise throughout the world. It is physicians and researchers to take scientific research based appropriate action to overcome this ever-spreading problem. This study is designed to find out sensitive (S), resistant (R) and multi-drug resistant (MDR) Acinetobacter baumanii strain along with other isolates in the resident patients of Eastern Region of Saudi Arabia. Pseudomonas aeruginosa is excluded from other gram-negative organisms isolated from different sites as it will be dealt separately. This study is based in was retrospective observations designed to collect data of different stains of Acinetobacter baumanii with reference to their Sensitivity (S), Resistance (R), Multi-Drug Resistance (MDR) along with other Gram negative isolated from different sites (from 1st January 2004 to 31st December 2011) at King Abdulaziz Hospital located Eastern Region of Kingdom of Saudi Arabia (KSA). All necessary techniques were used to culture and perform sensitivity of these isolates. There were 4532 isolates out of which 3018 (67%) were from patients. Out of Acinetobacter baumanii infected were 906 (20%) while other 3626 (80%) isolates were miscellaneous. Numbers of patients or cases were 480 (53%) out of 906 isolates and numbers of patients or cases in other organisms were 2538 (70%) out of 3626 isolates. Acinetobacter baumanii infected patients 221 (46%) were male and 259 (54%) were female and the male and female ratio of 1:1.2. In other organisms this male female ratio was almost same. There was steady rise in number of patients and the hence the isolates from 2004 to 2011.

Current investigations of the motions of the Arabian and its neighboring plates are primarily based on GPS measurements obtained in the surrounding areas of the Arabian plate, with few stations actually located on the Arabian plate itself in the Kingdom of Saudi Arabia. In order to advance the knowledge of the dynamics of the Arabian plate and its intra-plate deformations, the General Directorate of Military Survey (GDMS), through a collaboration with the Institute of Engineering Surveying and Space Geodesy (IESSG), densified the GPS network in Saudi Arabia, covering nearly two thirds of the tectonic plate. Since July 2002, a network of 32 GPS stations has been established at locations of the Saudi Arabia geodetic network. At all of these GPS stations a concrete pillar has been used as the monument and the locations have been selected in order to give the broadest distribution of observing sites. During 2005, 27 additional GPS stations in the Hejaz and Asser Mountains in the south-western part of Saudi Arabia, have been established, with the GDMS GPS network now comprising a total of 59 stations. In this presentation we will introduce the new GPS network in Saudi Arabia established by GDMS and will present the initial results from campaigns in March 2003 and March 2005. We show preliminary estimates of absolute and relative Arabian plate motions inferred from the GPS network and a detailed comparison of the results based on the Bernese GPS software versions 4.2 and 5.0.

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.

The use of khat (Catha edulis) is a major public health and social problem that is believed to be growing globally. The khat chewing habit is prevalent in all areas of the Jazan region, Kingdom of Saudi Arabia (KSA). However, few studies have been conducted at the community level to investigate the khat chewing habits in this area. This study was conducted with the aim of assessing the prevalence and predictors of khat chewing among the Jazan community population. A cross-sectional study was conducted with a sample (n = 4,500) of the Jizani population who attended primary heath care centers in Jazan region. The participants were selected using a two-stage cluster random sampling. A structured questionnaire was used for data collection. The overall lifetime prevalence of khat chewing was 33.2% (95% CI 31.8-34.7) and was significantly higher for males 42.2% (95% CI 40.4-43.9) than for females 11.3% (95% CI 9.6-13.1) (P < 0.001). Current khat chewers accounted for 28.7% (95% CI 27.4-30.1) of the population sampled; 36.9% (95% CI 35.2-38.6) of whom were males, which is a significantly higher percentage than the 8.7% (95% CI 7.3-10.4) of current khat chewers who were females (P < 0.001). The multivariate logistic regression analysis suggests that the most important independent predictors of khat chewing were having a friend who chewed khat (OR = 20.1, P < 0.001), participant's smoking status (OR) = 3.9, P < 0.001), friend's smoking status (OR = 2.2, P < 0.001), gender (OR = 2.2, P < 0.001) and educational level (OR = 1.5, P < 0.05). A large proportion of the Jizani populations chew khat. Government and non-governmental organizations NGOs should design and strengthen community prevention programs to curb the high prevalence of khat use. PMID:26247471

Flash flooding, as a result of excessive rainfall in a short period, is considered as one of the worst environmental hazards in arid regions. Areas located in the western provinces of Saudi Arabia have experienced catastrophic floods. Geomorphologic evaluation of hydrographic basins provides necessary information to define basins with flood hazard potential in arid regions, especially where long-term field observations are scarce and limited. Six large basins (from North to South: Yanbu, Rabigh, Khulais, El-Qunfza, Baish and Jizan) were selected for this study because they have large surface areas and they encompass high capacity dams at their downstream areas. Geographic Information System (GIS) and remote sensing techniques were applied to conduct detailed morphometric analysis of these basins. The six basins were further divided into 203 sub-basins based on their drainage density. The morphometric parameters of the six basins and their associated 203 sub-basins were calculated to estimate the degree of flood hazard by combining normalized values of these parameters. Thus, potential flood hazard maps were produced from the estimated hazard degree. Furthermore, peak runoff discharge of the six basins and sub-basins were estimated using the Snyder Unit Hydrograph and three empirical models (Nouh’s model, Farquharson’s model and Al-Subai’s model) developed for Saudi Arabia. Additionally, recommendations for flood mitigation plans and water management schemes along these basins were further discussed.

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.

No patients tested IgM positive, and 9410 (91.6% were immune (IgG positive; the remaining 866 (8.4% were susceptible. There were no significant differences in gravidity, parity, or the number of previous abortions between immune and nonimmune groups. In contrast, the immunity rate decreased with increasing age, with a significant difference between the youngest age group (15–19 years and the oldest age group (40–49 years (P=0.0005; odds ratio, 2.86; 95% confidence interval, 1.7–4.7. Rubella immunity among pregnant women was high (91.6% but decreased significantly with increasing age. A possible explanation for this is the change in the rubella vaccination policy in Saudi Arabia in 2002, from 1 dose to 2 doses. In addition, antibody levels begin to decline after vaccination and natural infection.

The purpose of this study was to determine the prevalence of subclinical mastitis in camels in Riyadh, Saudi Arabia and the factors influencing its incidence. A total of 740 quarter milk samples were collected from 47 camel herds belonging to Majahim, Maghatir, Shu'l, and Sufer breeds. California mastitis test (CMT) was used as a screening test for subclinical mastitis. Samples giving negative or trace CMT scores (0) were assigned to healthy quarters, while those giving positive scores of 1+ to 3+ were assigned to subclinically affected quarters. Logistic regression was used to assess the association of breed, parity, and stage of lactation with the prevalence of subclinical mastitis. Milk fat, protein, lactose, solid nonfat percentages and Na, Ca, and K concentrations were compared in CMT-positive versus healthy quarters. One third (33%) of tested quarters had subclinical mastitis based on CMT. The estimated probability of subclinical mastitis with the combined effects of breed, parity, and stage of lactation ranged from 15.8% to 54.6%. The risk of subclinical mastitis increased significantly with parity and with the early stage of lactation. The Shu'l breed had significantly higher prevalence of subclinical mastitis than other breeds. Significant decreases in protein, lactose, and solid nonfat, Ca and K concentrations and increase in Na concentrations were associated with subclinical mastitis. In conclusion, subclinical mastitis is prevalent in Saudi camels, and its incidence is influenced by breed, parity, and stage of lactation. PMID:21637994

This study was conducted in Jazan region of south-western Saudi Arabia. Vegetation cover, frequency, abundance and soil characteristics were analysed at three locations with different quantitative and descriptive vegetation characteristics. Plant species were classified into three primary communities dominated by Salvadora persic, Acacia tortilis and Ziziphus spini-Christi. The results indicated that the distribution of plant species is controlled by soil characteristics. Very limited water resources are also limiting factor in vegetation growth. Among the three studied sites, desert and coastal environments are affected by desertification. Rehabilitation of the degraded lands requires collaborative efforts and support from the different related governmental sectors. Ecological conservation and sustainable development must be adopted as tools of rehabilitation. PMID:26879985
Seasonal (winter-summer) indoor and soil radon comparison is made in two villages in Najran region, south west of Saudi Arabia, using CR-39 Dosimeter. Summer indoor radon concentrations were measured in the villages of Fara Al-Jabal and Hadadah. The respective winter-summer average values of 42 ± 4 Bq m−3 and 74 ± 5 Bq m−3 are measured in Fara Al-Jable village and the average values of 47 ± 4 Bq m−3 and 76 ± 5 Bq m−3 are measured in Hadadah village. The respective winter-summer soil values are 1.40 ± 0.21 kBq m−3 and 0.99 ± 0.04 kBq m−3 in Fara Al-Jabal village while those measured in Hadadah village are 2.90 ± 0.17 kBq m−3 and 1.40 ± 0.66 kBq m−3. Indoor radon levels are found to be seasonal dependent while that of soil are found seasonal and location dependent. Meteorological and geological factors are expected to have caused the measured significant differences in radon levels in dwellings and soil in the two villages. - Highlights: • Indoor and Soil radon levels are measured in Najran region, Saudi Arabia. • Indoor radon levels are location independent but seasonal dependant. • Soil radon levels are seasonal and location dependent. • Meteorological and geological factors may have caused the differences

Full Text Available The present work was carried out in Jazan region. The region of Jazan in being in the South-Western part of Saudi Arabia between longitudes 420 and 43.80 and latitudes 5, 16o and 17o, and is bounded on the south and east of the Republic of Yemen, Asir area in the north and the Red Sea in the west. The results showed that there are four families of poisonous snakes "Proteroglyphous" living in Jazan region. They are: Family Atractaspididae, Elapidae, Viperidae and Hydrophiidae . This work aimed to unveil ecological problems and throw light on diversity of poisonous snakes in Jazan region and the danger of these species to human life. Despite the fact that these snakes may be harmful to human life in some cases, it may also be useful to him in many aspects of life. Since there are no enough studies on the animal species in the region, this study came to identify the diversity of this animal group. There is no doubt that the study of these species and identifying them will provide some solutions that could make this group as an endless source of biodiversity and at the same time, this study provides information on the feasibility of protection of this species in this region. Discussion of ecological and geographical affinities of this taxa and taxonomic keys of different types in order to facilitate the process of identification will be provided
Water resources controlling, predicting, and decision making require a high resolution and reliable estimates of precipitation. Precipitation events significantly important and have a huge impact on the economy, the environment, and the society, especially in the largely arid countries. Recently, with the leap of developing satellite-retrieved precipitation products with high special resolution and global coverage that resulted in new source of sustainable precipitation estimates. However, the incorporation between satellite- retrieved estimates and the operational decision making are not well recognized due to lack of information towards uncertainties and consistency. In this study, the primary goal was to evaluate the performance of satellite products rainfall estimator (TRMM-3B42) and (PERSSIAN)around Saudi Arabia, by analyzing the TRMM-3B42 product for the period of January 2000- October 2010 and the PERSSIAN product for the period of March 2000 until December 2007. Independent rain gauge data were collected from over 29 local precipitation gauge stations from all thirteen provinces located in Saudi Arabia. After aggregation and interpolation, this data was specifically used to diagnose systematic differences between in-situ based rainfall and satellite derived rainfall using an extensive selection of validation metrics. The results show according to the probability of detecting rainfall amounts and volume of correctly identified precipitation, TRMM data sets led to better estimates and high correlation than PERSIANN product. Whereas in the false alarms ratio is higher in TRMM than in PERSSIAN. In fact, all precipitation products tend to miss a significant amount of rainfall. From the analysis, a recommendation suggested to extend the efforts towards necessary development of algorithms that capture precipitation with more consistency.

Full Text Available Ahmed M Bawazeer,1,2 Heba Ismail Joharjy1 1Uveitis Services, Department of Ophthalmology, King Abdulaziz University, 2Magrabi Eye and Ear Hospital, Jeddah, Saudi Arabia Background: The association of human leukocyte antigen B27 (HLA-B27 with anterior uveitis is well known. The prevalence of HLA-B27 and its relation to anterior uveitis is related to race and geographic location. The association is strongest in Western countries and weakest in Eastern countries. Data regarding this association from Middle Eastern countries are limited. Thus, we undertook the study reported here to evaluate the association of HLA-B27 with anterior uveitis in patients in a tertiary center in the western region of the Saudi Arabia. Methods: The study involved a retrospective analysis of the records of patients with anterior uveitis, referred to the uveitis clinic in Magrabi Eye and Ear Hospital, Jeddah, Saudi Arabia, from 1999 to 2010. The cost-effectiveness of HLA-B27 testing was analyzed. Results: Among the 587 cases of uveitis, 335 (57.1%; mean age 37.56±12.82 years; 203 male and 132 female cases were of anterior uveitis. All patients with anterior uveitis were investigated for HLA-B27 positivity. Idiopathic anterior uveitis was the most common (80%, followed by Fuchs heterochromic cyclitis (7.45% and ankylosing spondylitis (3.8%. Only two patients were HLA-B27 positive. The cost-effectiveness of HLA-B27 testing was found to be 165,000 Saudi riyals (44,594 US dollars per positive case. Conclusion: HLA-B27-related uveitis appears to be very rare in our part of the world. Idiopathic uveitis is the most common type of anterior uveitis. The cost-effectiveness of HLA-B27 testing is low for patients with anterior uveitis in the western region of Saudi Arabia. Keywords: HLA-B27, Saudi population, cost-effectiveness, idiopathic anterior uveitis, Fuchs heterochromic cyclitis, ankylosing spondylitis
Full Text Available This study investigated possible implications of climate change on crop water requirements (CWRs from 2011 to 2050 in Al-Jouf, Saudi Arabia. CWR were predicted for four scenarios: (i current temperature and rainfall (S1; (ii temperature in 2050 and current state of rainfall (S2; (iii rainfall in 2050 and current state of temperature (S3 and (iv temperature and rainfall in 2050 (S4. Assuming no change in the regulations relating to agriculture and irrigation in future, CWR were predicted to be 873 and 931 million cubic meters (MCM per year for the S1 and S4 scenarios, respectively, indicating an increase of 58 MCM from 2011 to 2050. On an average, 1 °C increase in temperature may increase the overall CWR by 2.9% in this region. Following linear pattern of increase, slope of CWR was determined as 1.5 MCM/year from 2011, which is equivalent to the CWR of producing approximately 600 tons of wheat/year. The increase of CWR was due to the increase in temperature mainly, while the effect of rainfall changes was minimal. Sensitivity analysis on crop growing seasons showed that the shift of wheat growing season might conserve significant amount of groundwater. This study might be useful in explaining the negative effects of climate change on CWR in Al-Jouf and better planning for water resources management.
The current study was conducted to figure out the relationship between the social structure and the most predominant environmental kids diseases (1-12 years old) in the community of Jihad city through year 1423.A.H. The results revealed that the dominant husband and wives age-groups were 30-40 Y, couples had Bachelor education level and governmental employees. Residences were distributed between down town and its periphery toward north , apart of red sea coast. They had 2-4 child/family of equal gender ratio. Most of couples were non relative. Wives education level was positively correlated with kids skin, respiratory and ocular diseases but negatively correlated with presence of servant and her health certificate. Private hospitals and health care centers were permanently accessed and located far of industrial collections. Majority of teachers and students were Saudis. Schools subjected their students for regular vaccination programs offered by Health Ministry. School services and facilities (regular vaccination, healthy foods and water) significantly affected incidence and kinds of kids diseases. Mixing nationalities may represent risk health for coming exotic infection unless restricted hygienic measures offered by Health Ministry. Husband job was negatively correlated with respiratory diseases. Husband job sector and their work places indoor air quality, their smoking behavior may affect directly or indirectly child diseases. The kids medicinal diseases were within husband age group 20-30 Y. Dominant kids diseases were within age-group 2-4 years mainly respiratory (dyspnea were highest respiratory affection within 1-12 Y children), skin and ocular affections. The dominance of respiratory diseases within infants in winter and the skin diseases in summer Most of kids diseases (skin, respiratory, ocular, medicinal, psychic and non recognized diseases agents were significantly correlated with their homes address.

Saudi Arabia is a country of the first importance because of its oil reserves (26% of the known world reserves) and its oil production: the third of the whole Opec production. This energetic gold mine finances up to 75% of the budget and assures 90% of its exports. The capacity of Saudi Arabia to refine crude oil is now comparable to that of France. Nevertheless the inflexibility of government expenditures makes foreign investors necessary to a balanced industrial development. It is expected that the Board of Trade soon presents some dispositions in order to promote and ease the opening to foreign investors. (A.C.)

The region of Asir is located in the southwestern part of the Kingdom of Saudi Arabia between longitudes 41 - 45 E and latitudes 17 - 21 N. Known for its natural beauty and cool climate delight the visitors and the region has become a destination for tourists. One of the main problems in the Asir region is the high demand for water during tourism seasons especially in view of the rapidly growing tourism sector. Flourishing tourism in the region is challenged by the scarcity of water resources and there is urgent need to identify alternative sources of potable water. It is found that fog water collection is a viable resource and Asir region is the most suitable location for fog water harvesting. An operational fog water collection project was initiated in 2007 to provide fresh water supply. Al-Sooda, situated at an altitude of about 3,000 m, was identified as the most suitable experimental site and two large fog collectors measuring 20 m by 2 m each were erected in 2009. The distance between the two sites is about 2 km. This paper gives the methods used to select the experimental site and the design of the large fog collection system. The fog collectors are flat rectangular nets supported by a post at both ends and arranged perpendicular to the direction of the prevailing wind. The collection surface, comprising two layers of black polypropylene mesh net, is fastened laterally to the posts with a set of fastening bars. The aluminum trough located below the mesh net catches the water that runs down the net and carries it to a pipe connected to the storage tank. Because the fog collectors are long and require space for guy wires for the posts, the basic site consideration is that at least 25 m of horizontal land available for the erection. Meteorological instruments and the portable weather station are used to measure the climatic data which are recorded three times a day, namely at 7:00, 14:00 and 19:00 h. On average, yields of about 5 to 6 L/m2 per day are collected

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 health care physicians and other general practitioners so as to decrease referrals to dermatology clinics (Author).

[Purpose] The goal of this study was to examine potential differences in physical therapists’ perceptions of content areas for the new entry-level Doctor of Physical Therapy (DPT) curricula and specialties for post-graduate residency and fellowship programs among five geographical regions in Saudi Arabia. [Subjects and Methods] All physical therapists in Saudi Arabia were invited to participate in this cross-sectional study, which was conducted via a web-based survey. The first domain queried the importance of introducing 10 content areas into future DPT curricula. The second domain concerned the importance of developing residency and fellowship programs in nine subspecialties. Descriptive statistics were generated, and an analysis of variance with a post hoc Tukey’s HSD test was used to evaluate the significance of differences in the physical therapists’ perceptions across the geographical regions. [Results] In total, 148 participants responded to the survey. Significant differences were found among respondents in different geographical regions for 4 of the 10 skills and 3 of the 9 subspecialties. [Conclusion] Understating the variations between the five regions would be helpful in developing a new model for future DPT and post-professional programs that addresses potentially unique needs perfectly. Future research is needed to confirm the findings in a wide range of stakeholders. PMID:25276019

Full Text Available Availability of data on agricultural activities and production are essential for an appropriate socio-economic planning and sustainability. This study was conducted using a questionnaire that was randomly distributed to farmers to identify some features of the agricultural activities in Hail region and to serve as baseline data on agricultural practices. The questionnaire was divided into main topics including socio-economic status of farms, farm area, main crops, production systems, agricultural practices, financial support, and use of wind breaks, water conservation, animal husbandry and marketing. Some of the results showed that date palms and alfalfa fodder were found to be the main grown crops in addition to citrus, grapes, vegetables, wheat and Rye. In most cases, all these crops were cultivated in open fields, compared to only 18% grown in green houses. About half of the farmers adopted the monoculture system and only 44.9% of them applied the crop rotation. More than 70% of farmers raise animals and the most commonly reared animal are sheep (53.6% followed by goats (23%, camels (18% and poultry (4.5%. The study revealed that Hail region is an important agricultural area in KSA and some agricultural practices need to be revised and directed towards sustainability through extension programmes.

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

Landsat multispectral scanner (MSS) band and band-ratio databases of two scenes covering the Midyan region of northwestern Saudi Arabia were examined quantitatively and qualitatively to determine which databases best discriminate the geologic units of this semi-arid and arid region. Unsupervised, linear-discriminant cluster-analysis was performed on these two band-ratio combinations and on the MSS bands for both scenes. The results for granitoid-rock discrimination indicated that the classification images using the MSS bands are superior to the band-ratio classification images for two reasons, discussed in the paper. Yet, the effects of topography and material type (including desert varnish) on the MSS-band data produced ambiguities in the MSS-band classification results. However, these ambiguities were clarified by using a simulated natural-color image in conjunction with the MSS-band classification image.

Full Text Available Purpose: To evaluate the prevalence of diabetic retinopathy (DR in the urban and rural areas of Al Hasa region of Saudi Arabia and to determine risk factors related to DR. Materials and Methods: This study was conducted on patient attending primary health care centers between July 2007 and June 2009. A retrospective chart review was conducted on subjects with diabetes mellitus greater than 18 years old. Ophthalmologists examined DR status through dilated pupils by using direct, indirect, and slit lamp bio-microscopy. Frequencies, percentage, and their 95% confidence intervals (CIs were calculated. Odd′s ratio was used to associate DR with possible risk factors. A P value less than 0.05 was considered statistically significant. Results: The prevalence of DR among 473 diabetic subjects was 30% (95% CI: 25.80-34.20. The odd ratios (ORs of DR among diabetic residing in an urban area was significantly higher than diabetics residing in rural areas [OR = 1.94 (95% CI of OR 0.82-2.89]. DR was associated to the duration of diabetes (adjusted OR = 1.70, uncontrolled blood sugar level (adjusted OR = 1.96, hyperlipidemia (adjusted OR = 2.04, and hypercholesterolemia (adjusted OR = 2.80. Conclusions: DR appears to be a public health problem in the Al Hasa district of Saudi Arabia, and a planned approach is required to avoid severe visual impairment in patients with diabetes mellitus. Primary prevention and early detection could be implemented through primary health centers and non-ophthalmologists.

Escarpment highways, roads and mountainous areas in Saudi Arabia are facing landslide hazards that are frequently occurring from time to time causing considerable damage to these areas. Shear escarpment highway is located in the north of the Abha city. It is the most important escarpment highway in the area, where all the light and heavy trucks and vehicle used it as the only corridor that connects the coastal areas in the western part of the Saudi Arabia with the Asir and Najran Regions. More than 10 000 heavy trucks and vehicles use this highway every day. In the upper portion of Tayyah valley of Shear escarpment highway, there are several landslide and erosion potential zones that affect the bridges between tunnel 7 and 8 along the Shear escarpment Highway. In this study, different types of landslides and erosion problems were considered to access their impacts on the upper Tayyah valley's bridge along Shear escarpment highway using remote sensing data and field investigation. These landslides and erosion problems have a negative impact on this section of the highway. Results indicate that the areas above the highway and bridge level between bridge 7 and 8 have different landslides including planar, circular, rockfall failures and debris flows. In addition, running water through the gullies cause different erosional (scour) features between and surrounding the bridge piles and culverts. A detailed landslides and erosion features map was created based on intensive field investigation (geological, geomorphological, and structural analysis), and interpretation of Landsat image 15 m and high resolution satellite image (QuickBird 0.61 m), shuttle radar topography mission (SRTM 90 m), geological and topographic maps. The landslides and erosion problems could exhibit serious problems that affect the stability of the bridge. Different mitigation and remediation strategies have been suggested to these critical sites to minimize and/or avoid these problems in the future.

Objectives: To assess knowledge regarding the management of odontogenic infections by dentists in Jeddah, Kingdom of Saudi Arabia. Methods: In this cross-sectional study, 150 practitioners responded to a 26-item paper-based questionnaire between August and December 2014. The questionnaire evaluated knowledge and current clinical practices in managing odontogenic infections, as well as the attitude towards antibiotic use and resistance in the community. Basic medical knowledge (BMK) and critical knowledge (CK) scores were calculated from the dentists’ response to these questions and were compared according to educational level (bachelor and postgraduate degree holders). Results: The mean BMK score was 1.98 ± 0.4 and CK score was 1.89 ± 0.3. Dentists with bachelor’s degrees had higher BMK scores than those with a postgraduate degree (p=0.005), but CK was not significantly different (p=0.400). Most dentists (77%) would prescribe antibiotics after a routine dental extraction, and would undertake definitive surgical treatment (49.2%) only after a localized space infection developed. Although 82.2% agreed that routine prescription of antibiotics increases bacterial resistance in the community, 71% believe that prescribing an antibiotic after routine oral surgical procedures prevents odontogenic infections. Conclusion: Dentists in Jeddah require further education through lectures and workshops to stay up to date on current concepts in odontogenic infection management. PMID:27052288

In countries with absolute water scarcity such as the Kingdom of Saudi Arabia (KSA), large-scale actual evapotranspiration estimation is of great concern in water use practices. Herein, spatial and temporal distribution of actual evapotranspiration (AET) in the western and southern regions of KSA during 1992-2014 was estimated using the SEBAL model with field observations. Zonal statistics for each land use-cover type were also identified, in order to understand their effects on water consumption. In addition, daily and seasonal water consumption for major crops was computed. Results revealed a gradual increase in monthly AET values from January to April and subsequent decline from May to December. The maximum monthly AET values were observed for irrigated cropland in southwestern, central, and southeastern regions of Asir Province, central and southwestern regions of Al-Baha Province, central and the plains region of Jazan Province, southern portion of Makkah Province, and limited areas in the northern regions of Madinah Province. The annual AET ranged from 418.8 to 3442.3 mm yr-1. The normal distribution of mean annual AET values ranged from 717 to 1020 mm yr-1. Forty-two percent of the study area had an annual AET that ranged from 717 to 1020 mm yr-1. The second highest range of frequencies was concentrated around 1020-1322 mm yr-1, representing the majority of agricultural land. The consumptive water use of the different land cover types in study area indicated that irrigated cropland which occupied 14.6% of the study area had AET rates much higher than other land uses. Water bodies are the next highest, with forest and shrubland and sparse vegetation slightly lower, and very low AET rates from bare soil. Daily and seasonal water consumption of major cropping systems varied spatially depending on cropping practices and climatic conditions.

This study was performed to determine the levels of eight heavy metals in irrigation well water and soil and to assess the suitability of some leafy green plants that are commonly cultivated in the Al-Kharj region, Saudi Arabia, for human consumption using an atomic absorption spectrometer. The mean concentrations of metals ranged from 0.0001 to 0.436 mg/L in well water and from 0.248 to 164.52 mg/kg in soil. The heavy metal concentrations showed significant differences among the different leafy green plants studied. Parsley (4.98 mg/kg) exhibited higher levels of Pb than other leafy green plants, whereas mallow (0.097 mg/kg) revealed greater amounts of Cd than other plants. All of the leafy green plants retained essential metals (Cu, Zn, Fe and Mn) more than the toxic metals (Pb and Cd). The levels of some of the metals in the leafy green plants were found to meet the FAO/WHO-recommended limits. The monitoring of heavy metals in leafy green plants must be continued because these plants are the main source of food for humans in many parts of the world and are considered to be bio-indicators for environmental pollution.

Saudi Arabia is an arid and the largest country in the middle east with a total land area of 2.253 x 10(6) km2. Recent urban and rural expansion has shown manifold increases in water use in various sectors. Water resources are limited and non-renewable coupled with unpredicted scanty rainfall. In order to meet the rising water needs, evaluation of water quality is important for allocation to various uses. A total of 101 well water samples were collected from Al-Ahsa Oasis. Water samples were analyzed for total salt concentration, pH, Ca, Mg, Na, K, HCO3, Cl, SO4, NO3, F and B contents. Soil Salinity Development (SSD), adjusted sodium adsorption ratio (adj.SAR), adjusted sodium adsorption ratio (adj. R(Na)) and Exchangeable Sodium Percentage (ESP) were calculated. The EC of groundwater ranged between 1.23 and 5.05 dS m(-1). Sodium was the most abundant cation followed by Ca, Mg and K in descending order. Chloride was the most abundant anion followed by SO4 and HCO3 in groundwater of Al-Ahsa Oasis. A significant correlation was found between Na and Cl (R2 = 0.936). Thermodynamics calculation revealed that an appreciable amount of Ca and Mg is associated with Cl and SO4 ions. The SAR and ESP values are within the permissible limits according to Ayers and Westcot, 1985. The NO3 concentration is within safe limits for drinking purpose according to WHO (1998) standards. The Saturation Indices (SI) indicated that groundwater is under-saturated (negative SI) with respect to certain minerals (for example: calcite, dolomite, gypsum, anhydrite, halite, pyrite, fluorite and aragonite) and oversaturated (positive SI) with respect to some other minerals (For example: Goethite, Siderite and hematite). The negative saturation index (SI) reveals that most of minerals are in un-saturated state and will dissolve more Ca and Mg into the soil solution after irrigation. A good relationship exists between Cl and other ions (Na, Ca and Mg) as well as between SO4 and Ca and Mg ion of

The region covered by this work includes three of the main tectonic units of the Arabian Shield: the Afif continental terrane, the Nabitah suture with its associated mobile belt, and the Asir ensimatic arc terrane. The geology of the area is well understood, and this geochronologic and isotopic study confirms that the Afif terrane was a continental microplate in the late Proterozoic. The study also provides a time frame for the crustal evolution of this part of the Shield. U-Pb zircon age data from a pelitic garnet-sillimanite gneiss of the Kabid formation shows that this part of the continental basement in the Afif terrane may be as old as 1830 Ma. Isotope data indicate that lead from the Kabid gneiss resided in the upper continental crust for a long period before 1830 Ma, and require that Archean rocks exist at depth beneath the Afif terrane.
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)

Globalisation is often thought to advocate for a single set of beliefs and customs and for a rejection of the need to protect regional cultures and traditions. In the aftermath of 9/11, the rift between Western and Arab cultures has deepened, and there is a patent need for cultural bridges to be built. The government of Saudi Arabia has, by increasing funding for higher education through grants and scholarships, enabled Saudi students to study at overseas universities. A number of non-Saudi students are also enrolled at Saudi Arabian universities. After a brief introduction to the cultural and educational history of the Arab region and Saudi identity, this article turns to contemporary higher education in Saudi Arabia. It introduces the King Abdullah Scholarship Programme and then goes on to present detailed enrolment data for 2006-2009, demonstrating trends and policy changes and identifying patterns in student mobility.

BACKGROUND Although virologically confirmed dengue fever has been recognized in Jeddah, Saudi Arabia, since 1994, causing yearly outbreaks, no proper seroepidemiologic studies on dengue virus have been conducted in this region. Such studies can define the extent of infection by this virus and estimate the proportion that may result in disease. The aim of this study was to measure the seroprevalence of past dengue virus infection in healthy Saudi nationals from different areas in the city of J...

We described a Saudi patient infected with Diphyllobothrium latum D. latum. A 38-year-old male presented, complaining of passing worms. He had a history of recent travel to Europe and South East Asia. Stools examination revealed typical D. latum eggs. He was treated with praziquantel followed by saline purge, after which he discharged an intact tapeworm. Macroscopic and microscopic examinations of the worm confirmed the diagnosis of D. latum. This is the first case of diphyllobothriasis to be reported in Saudi Arabia. The epidemiology and methods of prevention of diphyllobothriasis are discussed. (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. 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
This paper reports that foreign oil companies with concessions in northern Yemen have been drawn into a border dispute between Yemen and Saudi Arabia. At least six companies received letters from the Saudi government warning them that steps, as yet undefined, will be taken if exploration extends into disputed areas. A second territorial dispute also appears to be brewing in the region. Iran has ejected United Arab Emirates nationals from the island of Abu Musa in the Persian Gulf, which is jointly administered by Iran and Sharjah, one of the emirates. The U.A.E. government has reported the situation to the Gulf Cooperation Council, triggering a denial from Iran that anyone has been deported from the island
Objective was to determine the negative appendectomy rate; utilization, accuracy of Alvarado scale, ultrasound (US), computed tomography (CT) in diagnosis of acute appendicitis. Hospital records of 124 female patients admitted for suspicious of acute appendicitis from January 2003-January 2004 to the Emergency Department (ED) at King Abdul-Aziz University Hospital Jeddah, Saudi Arabia were reviewed retrospectively. We reviewed the age of patients, clinical presentation, Alvarado scale, US, CT, histopathalogical diagnosis of appendicular specimen. A total of 124 female patients aged 6-64 years were presented to ED with right iliac fossa pain. Of the total, 103 patients have appendectomies (83.1%), 21 (16.9%) patients underwent conservative treatment. Prevalence of advanced appendicitis was 13.7% and negative appendectomy rate was 27.2%. Accuracy rate of appendicitis with Alvarado scale 67.7%, US was 57.9% CT was 66.7%. Postoperative correlation was found between advanced cases and Alvarado scale (r=0.338), and hospital stay duration (r=0.250, p<0.01). Clinical findings and experiments remain of major importance in appendicitis-diagnosis. When appendicitis appears with atypical presentations, it remains a clinical challenge. In such cases, laboratory and imaging investigation may be useful in establishing a correct diagnosis. Alvarado scoring system is easy, simple and cheap complementary aid for supporting the diagnosis of acute appendicitis especially for junior surgeons. (author)
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.

Medical device evaluation presents several unique challenges due to the great diversity and complexity of medical devices and their rapid technological evolution. There has been a variety of work conducted on the development of disease based registries and health surveillance systems in Saudi Arabia. However, the progress of medical device registry systems and post-market medical device surveillance systems remains in its infancy in Saudi Arabia and within the region. In 2007, a royal decree assigned the responsibility for regulating medical devices to the Saudi Food and Drug Authority (SFDA). Soon afterwards, the SFDA established the Medical Devices National Registry (MDNR) to house medical device information relating to manufacturers, agents, suppliers and end-users. The aim of this paper is to provide an overview on the Medical Device National Registry (MDNR) in Saudi Arabia and describe the current experience and future work of establishing a comprehensive medical device registry and post-market surveillance system in Saudi Arabia.

To describe the epidemiology and clinical features of stroke in a prospective and retrospective cohort of Saudi children and ascertain the causes, pathogenesis, and risk factors. The Retrospective Study Group (RSG) included children with stroke who were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the period July 1992 to February 2001. The Prospective Study Group (PSG) included those seen between February 2001 and March 2003. During the combined study periods of 10 years and 7 months, 117 children (61 males and 56 females, aged one month-12 years) were evaluated; the majority (89%) of these were Saudis. The calculated annual hospital frequency rate of stroke was 27.1/100,000 of the pediatric (1month-12 years) population The mean age at onset of the initial stroke in the 104 Saudi children was 27.1 months (SD=39.3 months) median and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). Large-vessel infarcts (LVI, 51.9%) were more common than small-vessel lacunar lesions (SVLL, 19.2%). Five patients (4.8%) had combined LVI and SVLL. Intracranial hemorrhage was less common (18.2%), whereas sinovenous thrombosis was diagnosed in 6 (5.8%) patients. A major risk factor was identified in 94 of 104 (89.4%) Saudi children. Significantly more hematologic disorders and coagulopathies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and

Full Text Available Background/Aims: Hepatitis B virus (HBV continues to be one of the most important viral pathogens in humans. Surface (S protein is the major HBV antigen that mediates virus attachment and entry and determines the virus subtype. Mutations in S gene, particularly in the “a” determinant, can influence virus detection by ELISA and may generate escape mutants. Since no records have documented the S gene mutations in HBV strains circulating in Saudi Arabia, the current study was designed to study sequence variation of S gene in strains circulating in Saudi Arabia and its correlation with clinical and risk factors. Patients and Methods: A total of 123 HBV-infected patients were recruited for this study. Clinical and biochemical parameters, serological markers, and viral load were determined in all patients. The entire S gene sequence of samples with viral load exceeding 2000 IU/mL was retrieved and exploited in sequence and phylogenetic analysis. Results: A total of 48 mutations (21 unique were recorded in viral strains in Saudi Arabia, among which 24 (11 unique changed their respective amino acids. Two amino acid changes were recorded in “a” determinant, including F130L and S135F with no evidence of the vaccine escape mutant G145R in any of the samples. No specific relationship was recognized between the mutation/amino acid change record of HBsAg in strains in Saudi Arabia and clinical or laboratory data. Phylogenetic analysis categorized HBV viral strains in Saudi Arabia as members of subgenotypes D1 and D3. Conclusion: The present report is the first that describes mutation analysis of HBsAg in strains in Saudi Arabia on both nucleotide and amino acid levels. Different substitutions, particularly in major hydrophilic region, may have a potential influence on disease diagnosis, vaccination strategy, and antiviral chemotherapy.
Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children. Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents. We selected a sample of children and adolescents aged from birth to 18 years by multi-stage probability sampling of the Saudi population. The selected sample represented Saudi children from the whole country. Data were collected through a house-to-house survey of all selected households in all 13 regions in the country. Data were analyzed to study the distribution pattern of systolic (SBP) and diastolic blood pressure (DBP) and to develop reference values. The 90th percentile of SBP and DBP values for each age were compared with values from a Turkish and an American study. A total of 16 226 Saudi children and adolescents from birth to 18 years were studied. Blood pressure rose steadily with age in both boys and girls. The average annual increase in SBP was 1.66 mm Hg for boys and1.44 mm Hg for girls. The average annual increase in DBP was 0.83 mm Hg for boys and 0.77 mm Hg for girls. DBP rose sharply in boys at the age of 18 years. Values for the 90th percentile of both SBP and DBP varied in Saudi children from their Turkish and American counterparts for all age groups. Blood pressure values in this study differed from those from other studies in developing countries and in the United States, indicating that comparison across studies is difficult and from that every population should use their own normal standards to define measured blood pressure levels in children.

proposed by the Ministry of Labor. American and Saudi workers are concerned about the quality and sufficiency of health and safety training, employment promotion, work pressure, and job uncertainty due to continuous downsizing. This article recommends that Saudi social actors increase safety and health awareness in the work environment by providing intensive occupational safety training to the employees (as demanded by Saudi and American workers), improve labor-management relations through establishing strong cooperative contacts with regional and international trade unions, and establish uniform and standard occupational health and safety regulations for Saudi Aramco and its subsidiaries in order to provide an equal level of protection for Saudi workers.

The present study was conducted to establish cephalometric norms of Saudi boys based on the Steiners analysis, and to compare the results of the present study with similar studies conducted on other racial or ethnic groups. For this purpose, fifty-five healthy Saudi boys, with a mean age of 12.04 years, were selected from different schools of Riyadh. Female Saudis were not used for this study due to social restrictions with respect to the Kingdom's customs and traditions. Selection was made on the basis of normal occlusion, balanced and pleasing profile with no obvious facial asymmetry. None of the boys have undergone orthodontic treatment prior to this study. Lateral skull cephaiograms were taken and traced using a standardized technique. Each cephalogram was traced twice with a one week interval by the authors. All angular and linear measurements were calculated to the nearest 0.5 degree and 0.5 mm, respectively. Steiners method of cephalometric analysis was used to establish cephalometric norms. The result of the study demonstrated that the Saudi boys differed from other racial and ethnic groups in some skeletal and dental measurements. Generally, the Saudi boys revealed a more protrusive maxillary apical base and double dental protrusion. (author)

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion: There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease. Riyadh, the eastern region, and Makkah
Osteoporosis is reported to be common among postmenopausal Saudi women. The reported incidence varies between 50-60%. Different machines were used to reach these conclusions. At present it is believed that dual energy x-ray absorptiometry (DEXA) is the most accurate method to diagnose osteoporosis. This study was conducted to measure bone mineral density (BMD) measurement of lumbar spine and the upper femur of Saudi postmenopausal women attending orthopedic clinic with unrelated complaints. This study comprises of 256 patients attending orthopedic clinics at King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia between January 2002 and June 2003. The data gathered was age, duration of menopause, height and weight for body mass index (BMI) calculation. Women with secondary osteoporosis were excluded from study. Patient's orthopedic complaints were also recorded in the database. Bone mineral density measurements were carried out using Hologic total body DEXA machine. The data were analyzed using SPSS package. The data of 256 patients was available for analysis. The average age of patients screened was 57.62 years (49-76) SD+-6.71. The BMI was 21.3-42.9 Kg/m (SD+-5.34). The BMD of lumbar spine was 0.785 gm/cm2 (0.527-1.023) SD +-0.142 and that of the hip region was 0.764 gm/cm2 (0.500-1.069) SD +-0.149. As per the WHO classification 59 women (23%) were classified as normal with the T score of -0.82, 78 (30.5%) as osteopenic with T score -2.5 and 119 (46.7%) as osteoporosis with T score -3.58. When the BMD of the hip was analyzed 62 (24.2%) were normal T score -1.0, 81 (31.6%) as osteopenic, T score -2.5 and 113 (44.1%0 as osteoporotic, with a T score of -3.1. on the basis of analysis of lumbar spine 190 (74.2%) had increased risk of fracture as compared to the analysis of hip 59% were at increased risk of fracture. Our results indicate that postmenopausal Saudi women suffer from osteoporosis and osteopenia higher than those from other parts of the

This area includes three of the main tectonic units of the Arabian Shield: the Afif continental terrain, the Nabitah suture with its associated mobile belt, and the Asir ensimatic arc terrain. U/Pb zircon data from a pelitic garnet-sillimanite gneiss show that the Kabib formation in the S of the Afif terrain may be as old as 1770 m.y. Pb and Rb/Sr isotopic data in the Zalm region reveal a change in the nature of the underlying crust, from continental basement in the NE to less radiogenic marginal arc rocks in the SW. Miogeosynclinal continental shelf facies of the Siham group lie unconformably over the Kabid formation. U/Pb zircon age determinations show that this 'Andean' continental margin developed before approx 720 m.y. and the emplacement of calc-alkaline plutonic rocks continued until approx 690 m.y. During the period 685-640 m.y. the continental Afif microplate collided with the Asir terrain as part of the Nabitah orogeny. At approx 640 m.y. age the Najd strike-slip faulting commenced, with a dextral phase that controlled emplacement of granite plutons as well as the development of large pull-apart grabens. Some of the latter were floored by new oceanic crust and filled with volcanosedimentary rocks of the Bani Ghayy group.-R.A.H.

During the past decade, the Kingdom of Saudi Arabia has undergone rapid economic growth and development. This expansion stems from the increase in the Kingdom's production of petroleum--oil being the source of most of the country's exports, foreign exchange, and government revenues. However, despite this growth, Saudi Arabia is one of the top foodstuff importers among developing countries. It has been estimated that the value of Saudi agriculture imports in 1981 increased about 33 percent to ...
Full Text Available Apis mellifera jemenitica Ruttner (= yemenitica auctorum: vide Engel 1999 has been used in apiculture throughout the Arabian Peninsula since at least 2000 BC. Existing literature demonstrates that these populations are well adapted for the harsh extremes of the region. Populations of A. m. jemenitica native to Saudi Arabia are far more heat tolerant than the standard races often imported from Europe. Central Saudi Arabia has the highest summer temperatures for the Arabian Peninsula, and it is in this region where only A. m. jemenitica survives, while other subspecies fail to persist. The indigenous race of Saudi Arabia differs from other subspecies in the region in some morphological, biological, and behavioral characteristics. Further taxonomic investigation, as well as molecular studies, is needed in order to confirm whether the Saudi indigenous bee populations represent a race distinct from A. m. jemenitica, or merely an ecotype of this subspecies.

Some common factors that affect dividend policy of both financial and non-financial firms, we found some factors that affect only non-financial firms. In particular, the common factors are profitability, size, and business risk. Government ownership, ...
Full Text Available The Saudi Initiative for Asthma (SINA provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system.
The future strategy of Saudi Arabia with respect to its oil production capacity is discussed. A major uncertainty affecting planning is the prospect of an Iraqi return to the market as and when Saddam Hussein falls or he manages to comply fully with all the UN resolutions and sanctions are lifted. It is believed that Iraq could at very short notice be capable of exporting 2mb/d of crude rising to 2.5 mb/d within a few months. This is 10% of OPEC's physically traded crude. Also taken seriously are Baghdad's assertions that Iraq will have a production capacity of about 6mb/d by the year 2000. Saudi officials are concerned that OPEC is not ready to tackle the impact of an Iraqi return to the market at a time when some OPEC members are producing above quota anyway. The most likely outcome is thought to be that OPEC would simply raise their nominal production ceiling. Against this background, Saudi Arabia has embarked on the exploitation of the gigantic oil reserves of the Shaybah field. This development offers the kingdom an ability, on the one hand, to increase its earnings while remaining within its OPEC quota and, on the other hand, to increase output substantially should it ever appear that its best interests are served by not adhering to quotas.

The Kingdom of Saudi Arabia includes fauna from three zoogeographic regions: the Afrotropical, Oriental, and Palaearctic regions. To study the mosquito (Diptera: Culicidae) fauna of these regions in Saudi Arabia, larval collections were made at 15 sites during 2005-2006. Thirty-three species representing nine genera were found. Six species, Anopheles culicifacies Giles s.l., Anopheles subpictus Grassi s.l., Culex arbieeni Salem, Culex simpsoni Theobald, Culex univittatus Theobald, and Ochlerotatus detritus Haliday are reported for the first time for Saudi Arabia. An annotated checklist and an illustrated key to the fourth-instar larvae of the 33 species are presented, along with some remarks about problematic species. Eleven species of genus Anopheles Meigen, five species of tribe Aedini, 13 species of genus Culex L., two species of genus Culiseta Felt, one species of genus Lutzia Theobald, and one species of genus Uranotaenia Lynch Arribátlzaga were recorded during the study.

Allergenicity Prosopis juliflora pollen antigen has been reported fromonly a few countries, including the US, South Africa, India and Kuwait. Insome parts of Saudi Arabia, species of Prosopis have been introduced by themillions as roadside ornamentation. There appear to be four flowering seasonsduring which pollen grains float in all directions. However, the role ofProsopis pollen as the sensitizing and/or rhinitis in the Kingdom has neverbeen evaluated. A total of 473 allergic patients suffering from the bronchialasthma in four different geographical regions (Abha, Qassim, Hofuf, Gizan),and attending allergy clinics and chest disease centers of university andMinistry of Health hospitals in the region were tested for immediatehypersensitivity reaction to Prosopis Juliflora allergens. Airborne pollengrains at one center were also studied for one full year, using volumetricsampling techniques. A total of 76.1% patients in Qassim, 37.5% in Gizan, 29%in Abha and 11% in Hofuf reacted positively to Prosopis antigen. Multiplesensitivities to other pollen antigens were detected in all patients. Thelevel of airborne Prosopis pollen detected in Gizan exceeded 90 grains m ofair. In view of documented evidence of Prosopis pollen as a sensitizingfactor in Saudi Arabia has been confirmed. However the cause of elicitationof symptoms in many multiple sensitive patients, together with the questionof cross-reactivities, needs thorough and detailed investigation. In vitroconfirmation of all positive results is also required to incriminate Prosopisas one of the major allergens in parts of Saudi Arabia. (author)

Full Text Available Objective: To assess the attitude of future physicians regarding the disclosure of diagnosis, prognosis, benefits, and adverse effects of therapeutic intervention if they happen to have cancer. It also examined the differences if any between regions or gender. Materials and Methods: A total of 332 medical students from University of Dammam, in the Eastern Province of the Kingdom of Saudi Arabia were surveyed using a self-administered questionnaire. The questionnaire consisted of nine questions on the attitudes to disclosure of information on cancer. This self-administered questionnaire was completed by the students in the presence of an investigator. Results: The vast majority of Saudi medical students stated that they would like to know about diagnosis of cancer (92.8% and only 7.2% wanted information withheld from them. Further, 67% of the males and 74.1% of the females wanted family members to know (P = 0.01, but one-third (33% did not want their family to know. Only 24.1% of the male and 21.1% of female students wanted their friends to know. In addition, -97% of the males and 98.8% of the females wanted to know the diagnosis, and 97% and 95.8% of females and males, respectively, would like to know the side effects of the therapy. Almost 95% of male and 93.4% of female students wanted to know the prognosis. Also, 98% of medical students from the Eastern Region would want the diagnosis of cancer to be disclosed compared to 73.6% of those from other regions (P = 0.01. There is no difference between the genders in attitudes toward the disclosure of the diagnosis, 94.6% and 92.2% (P = 0.38. Conclusions: There was a consensus among Saudi medical students on the knowledge of the benefits of treatment, adverse effects of therapy, and prognosis. Female students significantly more than males would like their families to be informed. Significantly more medical students from the Eastern Region than those from other regions would like the diagnosis of
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.
Adolescence is characterized by rapid physiological, social and cognititive changes. Aim of the present work is to study mental health of Saudi adolescent secondary school girls in Abha city, Aseer region, Saudi Arabia. A cross-sectional study was conducted in 10 secondary schools for girls using the Arabic version of the symptom-revised checklist 90 (SCL 90-R), a mental health questionnaire that was administered to the girls by fourth-year female medical students. The most prevalent mental symptoms in the 545 female students were phobic anxiety (16.4%), psycchoticism (14.8%), anxiety (14.3%), and somatization (14.2%). The prevalence of depression, paranoid ideation and interpersonal sensitivity amounted to 13.9%, 13.8% and 13.8%, respectively. The least prevalent mental symptoms were hostility (12.8%) and obsessive-compulsive behavior (12.3%). Overall, psychological symptoms (in terms of a positive global severity index) were found in 16.3% of the girls. In a multivariate logistic regression analysis, no significant relationship was found with sociodemographic factors. Psychological symptoms and disorders are prevalent in secondary school girls and health professionals need to be able to recognize, manage and follow-up mental health problems in young people. Further research is needed to explore the magnitude of the problem at the national level. (author)

This article examines the Kingdom of Saudi Arabia's gender-segregated higher education system and how it is used to transmit the Kingdom's traditional societal expectations to the employment sector. With Saudi Arabia's current need for economic change, the education system is retarding instead of accelerating reform. A background consisting of Saudi Arabian history, governing laws, religious beliefs and women's roles is examined. I then discuss the education system's preservation goal by cons...
This study describes and analyzes the process of development in Saudi Arabia in relation to oil revenues and Saudi Arabian dependence on imported foreign labor. Modern development and societal change in Saudi Arabia began with the commercial exploitation of oil in 1939, therefore Saudi economy must be viewed from a dual perspective: a highly capital-intensive oil sector and a labor-intensive non-oil sector. In one generation the Kingdom created an infrastructure suitable to a rapid transformation from Bedouin tribes to a modern state, which became a leading regional power and now occupies an important place in international society. Important advances were made in social services, health services and education at all levels. Large-scale importation of foreign labor workers during the 1970s and early 1980s was necessary for the Development Plans. By the 1990s the major infrastructure was completed and only the maintenance work and minor projects remained for foreign labor sources
Full Text Available This paper presents findings from a study examining the diffusion and adoption of online retailing in Saudi Arabia. Although the country has the largest and fastest growing Information and Communication Technologies (ICT sector in the Arab region, growth in e-commerce activities has not progressed at a commensurate rate. In general, Saudi retailers have not kept pace with the global growth of online retailing. The authors have conducted research to identify and explore key issues that influence Saudi retailers in deciding whether or not to adopt online channels. As part of a larger research project using mixed methods, this paper focuses on a quantitative analysis of responses obtained from a survey of retailers in Saudi Arabia. The design of the questionnaire instrument was based on the findings of a qualitative analysis reported in a previous paper. The main findings of the current study include a list of key factors that affect retailers’ e-commerce adoption, such as lack of online payment options and lack of clear legislation on e-commerce in Saudi Arabia, and quantitative indications of the relative strengths of the various relationships.

Full Text Available Climate change is an emerging global problem. It has hazardous effects that vary across different geographic regions and populations. It is anticipated to have significant effects in Saudi Arabia. The present work reviews the future of human parasitoses in Saudi Arabia in response to the expected climate change. The key projections are increased precipitations, flash floods, unstable temperatures, sea-level rise and shoreline retreat. Such environmental changes could strongly influence the epidemiology of fly-borne, mosquito-borne, snail-borne and water-borne human parasitoses in the country.

Objective:To study epidemiological trends related to cutaneous leishmaniasis (CL) in Al Hassa, an endemic area in Saudi Arabia. Methods: This retrospective study included the spatial/temporal analysis of the reported cases of CL using the available surveillance database for the disease at the regional Vector Control Unit, from 2000 to 2010. Results: The incidence of CL was declining at a stable rate especially during the last 3 years of the study (2008-2010). An interesting finding was the percentage of expatriates affected was increasing over the last 10 years compared to that of the Saudis. Conclusions:A definite declining trend in the incidence of CL was observed in Al Hassa. Further studies are warranted to assess whether special public health measures are needed for better control of CL in expatriate populations in Saudi Arabia.

In this article is described the economic situation of Saudi Arabia. In a first time, Saudi Arabia drew from external reserves to finance gulf war and covered its budget deficits, then the internal debts took over. The actual strategy in order to transfer from state to private national and foreign sector a great part of new projects financing is become a necessity to control the deficits in a country where state is strongly got in debt.

Objective was to determine the prevalence of osteoporosis in healthy Saudi men. We randomly recruited 429 Saudi men from the community. The recruited Saudi men were subjected to an interview to reveal their lifestyle parameters, calcium intake and level of activity. Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)
Full Text Available In view of the increasing concern among English language teachers dealing with students from Saudi Arabia, as it manifests in TESOL community discussions, about the uniqueness of Saudi Arabian EFL learners, this paper attempts to document the outcome of a study of their distinctiveness from the perspective of expatriate teachers working for PYPs (Preparatory Year Programs in Saudi Arabia. This study examines the distinctiveness with regard to the learning attitudes of Saudi students that are often cultivated by the culture and academic environment in their homeland. Employing an emic approach for collecting the required data an analysis was carried out in light of the other studies on ‘education’ in Saudi Arabia that have particular reference to the factors that can positively influence student motivation, student success and the academic environment. The findings were used in constructing the rationale behind such distinctiveness. Assuming that the outcome of the discussion on the findings of this exploration can be helpful for teachers in adapting their teaching methodology and improving their teacher efficacy in dealing with students both from the kingdom and in the kingdom, some recommendations are made.Keywords: China Distinctiveness, Saudi Arabian University context, Expatriate teachers’ perspective, Distinctiveness Theory
Chevron Chemical (Houston), encouraged by a new Saudi royal decree that establishes extremely low feedstock prices, is in final negotiations to build a novel aromatics plant in Saudi Arabia. Chevron says it plans to close the deal and announce details the first week of March. The unit will be based on Chevron's Aromax reforming process, which uses a zeolite catalyst to convert light naphtha into benzene and toluene. No existing plant is using the technology, but Chevron is building a $250-million, 150-million gal/year Aromax unit at its refinery site in Pascagoula, MS, and Idemitsu has licensed the process for a plant in Chiba, Japan. The Saudi decree, issued late last year, pegs domestic feedstocks - propane, butane, and naphthas - at 30% below the lowest price of the prior quarter in major non-domestic markets. That clarifies and guarantees the Saudi feedstock price, which has always been nebulous, and thus allows project feasibility to be more clearly assessed. The decree is designed to encourage further private petrochemical investment in the country. In particular, the Saudi government hopes guaranteed low prices for butane will encourage more methyl tert-butyl ether (MTBE) projects. Arabian American Chemical, a 50/50 joint venture between Mobile and Arabian Chemical Investments, said in October of last year that its 830,000-m.t./year MTBE project at Yanbu, Saudi Arabia, would go ahead if feedstock questions could be resolved. The decree apparently resolves those questions

The kingdom of Saudi Arabia is currently witnessing a massive support for its healthcare services. This year's fiscal budget for health care is by far the largest in the history of the kingdom. While pursuing the conventional goals of healthcare delivery systems, such as equity, affordability and availability of services, the ministry of education (MOE), formerly called ministry of higher education (MOHE), is also seeking to achieve certain excellence standards, which are expected to set the bar for other countries in the region to follow suit. Almost all, under construction, university hospitals were adopting a paradigm shift in the standard of health care and training provided. This report summarizes these standards. PMID:26984027

Nesidioblastosis is focal or diffuse islet hyperplasia leading tohyperinsulinism with subsequent hypoglycemia in the absence of insulinoma,usually described in neonates and infancy. We described the first adult caseof nesidioblastosis in Saudi Arabia and the Gulf region. The diagnosis andtreatment of the condition can be very difficult and challenging. Despite thefact that our patient responded initially to surgical treatment, hishypoglycemic symptoms occasionally recurred and needed adjunctive medicaltreatment. Although initially thought to affect only infants and children,cases of nesidioblastosis can effect adults and pose a diagnostic andtherapeutic challenge to the clinicians. (author)
Full Text Available Background: Vitamin D deficiency has been correlated with several diseases and injuries including diabetes, osteoporosis, fractures, and falls. In the Kingdom of Saudi Arabia (KSA, current data on vitamin D status are lacking. Aims: To inform Saudi public health authorities on the current status of blood levels vitamin D deficiency, we analyzed data from the Saudi Health Interview Survey. Materials and Methods: The Saudi Health Interview Survey (SHIS is a cross-sectional national multistage survey of individuals aged 15 years and above on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. A total of 10,735 participants completed a health questionnaire and were invited to the local health clinics for biomedical exams. Results: 62.65% of female Saudis and 40.6% of male Saudis aged 15 years and above are deficient in vitamin D. Out of them, less than 1% males and less than 2% females consume vitamin D supplements. Women who have never married and obese individuals are more likely to be deficient in vitamin D, compared to men who were currently married and nonobese individuals. Those consuming vitamin D supplements are less likely to be deficient in vitamin D. Conclusions: Our study showed a high prevalence of vitamin D deficiency among Saudi men and women, and the results call for an increased awareness to ensure adequate levels of vitamin D for better health in Saudi Arabia. Moreover, our findings are certainly relevant for other countries in the Gulf region or countries with similar cultures, clothing, and religions.

Meteorologists are required to provide accurate and comprehensive weather information for planning and operational aviation, agricultural, water projects and also for the public. In general, weather phenomena such as thunderstorms over the area between the tropics and the middle latitudes are not fully understood, particularly in the Middle East area, for many reasons such as: 1) the complexity of the nature of the climate due to the wide-ranging diversity in the topography and landscape in the area; 2) the lack of meteorological data in the area; and 3) the lack of studies on local weather situations. In arid regions such as Saudi Arabia, the spatial and temporal variation of thunderstorms and associated rainfall are essential in determining their effects on social and economic conditions. Thunderstorms form rapidly, due to the fact that the significant heating of the air from the surface and the ensuing rainfall usually occurs within a short period of time. Thus, understanding thunderstorms and rainfall distribution in time and space would be useful for hydrologists, meteorologists and for environmental studies. Research all over the world has shown, however, that consideration of local factors like Low Level Jets (LLJ), moisture flux, sea breezes, and the Red Sea Convergence Zone (RSCZ) would be valuable in thunderstorm prediction. The combined effects of enhanced low-level moisture convergence and layer destabilization due to upslope flow over mountainous terrain has been shown to be responsible for thunderstorm development in otherwise non-favourable conditions. However, there might be other synoptic features associated with heavy thunderstorms or cause them, but these features have not been investigated in any research in Saudi Arabia. Thus, relating the local weather and synoptic situations with those over the middle latitudes will provide a valuable background for the forecasters to issue the medium-range forecasts which are important for many projects

Over recent decades, the use of portfolios in medical education has evolved, and is being applied in undergraduate and postgraduate programs worldwide. Portfolios, as a learning process and method of documenting and assessing learning, is supported as a valuable tool by adult learning theories that stress the need for learners to be self-directed and to engage in experiential learning. Thoughtfully implemented, a portfolio provides learning experiences unequaled by any single learning tool. The credibility (validity) and dependability (reliability) of assessment through portfolios have been questioned owing to its subjective nature; however, methods to safeguard these features have been described in the literature. This paper discusses some of this literature, with particular attention to the role of portfolios in relation to self-reflective learning, provides an overview of current use of portfolios in undergraduate medical education in Saudi Arabia, and proposes research-based guidelines for its implementation and other similar contexts.

Full Text Available Medicinal plants are important in traditional medicine and modern pharmaceutical drugs; therefore, the interest in the analysis of their chemical composition is increasing. In this study, selected medicinal plants including Achillea fragrantissima (Forssk Sch., Amaranthus viridis L., Asteriscus graveolens (Forssk. Less., Chenopodium album L., and Conyza bonariensis (L. Cronquist were collected from the rangeland of western regions (Bahra and Hada areas of Saudi Arabia to study their chemical composition. Eight minerals (Mg, Ca, Cr, Mn, Fe, Co, Cu, and Zn, total phenolic contents, antioxidant activity, and free-radical scavenging ability were examined in order to evaluate the medicinal potential of these plants. All the plants were found to be rich sources of minerals and antioxidants, although there were significant differences (p < 0.05 in their chemical composition, which may provide a rationale for generating custom extracts from specific plants depending on the application. The findings of this study will thus facilitate herbalists in their efforts to incorporate these plants into various formulations based on their chemical composition.

Fish are a healthy source of protein and nutrients, but contaminants in fish may provide health risks. Determining the risk from contaminants in fish requires site-specific information on consumption patterns. We examine consumption rates for resident and expatriates in the Jeddah region of Saudi Arabia, by species of fish and fishing location. For Saudis, 3.7% of males and 4.3% of females do not eat fish; for expatriates, the percent not eating fish is 6.6% and 6.1% respectively. Most people eat fish at home (over 90%), and many eat fish at restaurants (65% and 48%, respectively for Saudis and expatriates). Fish eaten at home comes from local fish markets, followed by supermarkets. Saudis included fish in their diets at an average of 1.4±1.2 meals/week at home and 0.8±0.7 meals/week at restaurants, while expats ate 2.0±1.7 meals/week at home and 1.1±1.1 meals/week in restaurants. Overall, Saudis ate 2.2 fish meals/week, while expats ate 3.1 meals/week. Grouper (Epinephelus and Cephalopholis) were eaten by 72% and 60% respectively. Plectropomus pessuliferus was the second favorite for both groups and Hipposcarus harid and Lethrinus lentjan were in 3rd and 4th place in terms of consumption. Average meal size was 68. g for Saudis and 128. g for expatriates. These data can be used by health professionals, risk assessors, and environmental regulators to examine potential risk from contaminants in fish, and to compare consumption rates with other sites. © 2014 Elsevier Inc.

Full Text Available Objective: To examine self-reported knowledge, attitude, and preventive practices on cancer among Saudis. Materials and Methods: Data was collected from Saudis aged 15 years or more, who attended one of the randomly selected 20 Primary Health Centers (PHC or the four major private hospitals located in the Riyadh region, either as patients or their escorts. The association between the variables was evaluated by the Chi square test. Results: The study population consisted of 618 males and 719 females. Among the female respondents 23.1% reported that they practiced breast self-examination (BSE; 14.2 and 8.1%, respectively, had clinical breast examination (CBE and mammography. However, 10.0 and 16.1% of the females, aged 40 years and older, reported having had mammograms and CBE, respectively. The BSE performers were more educated, knew someone with cancer, and had heard of the cancer warning signal. Both educational level and ′heard of cancer warning signal′ were significantly related to CBE. Cancer information was received from television / radio by 65.1% and from the physician by 29.4%. Even though 69.4% believed that cancer could be detected early, a vast majority (95.8% felt early detection of cancer was extremely desirable and 55.1% said their participation was definite in any screening program. A majority of the respondents (92.6% insisted on the need for physician recommendation to participate and 78.1% expected that any such program should be conducted in the existing hospitals / clinics. Conclusion: Culturally sensitive health education messages should be tailored to fulfill the knowledge gap among all population strata. Saudis will benefit from partnerships between public health educators and media to speed up the dissemination of cancer information.

In the last decade, public health (PH) has come to the frontlines in Saudi Arabia. The recent outbreak of a novel corona virus (MERS-CoV) highlighted the importance of PH services and the need for a competent PH workforce. The urgency and panic induced by infectious disease outbreaks explain the heightened interest. Decision makers' interest in public health was observed through a series of decisions, including creating a position for Deputy Minister for Public Health, changing the name of "Directorate of Primary Healthcare Centers" to "Directorate of Public Health" in all health regions and initiating a special scholarship program to prepare health administration professionals in collaboration with US-based universities. A distinguished group of PH leaders in Saudi Arabia was gathered in a structured workshop that was organized by the Al Imam Mohammad Ibn Saud Islamic University, college of medicine to discuss the current status and future needs of PH education in the Kingdom of Saudi Arabia. The workshop highlighted the need for PH education development and outlined the challenges ahead. The main challenges laid out by participants in the workshop were the development of an appropriate PH curriculum, appropriate training spots for practical placement, the development of research priorities for PH to satisfy the needs of PH programs and agencies, attracting the most qualified academic staff, the enrolment of highly motivated students and finally, the establishment of a quality assurance program to ensure the quality of PH education programs. The development of a framework for graduate competencies in PH was perceived to be a top priority. Moreover, setting a PH workforce surveillance system, building partnership between PH academic institutions and PH services providers, implementing national campaigns to explain what PH is about and illuminating the role of PH workers were also of utmost importance.

Full Text Available The main objective of this research is to study the role of energy consumption in economic growth in Saudi Arabia over the period of 1971–2012 using the autoregressive distributed lag (ARDL cointegration procedure, and based on neoclassical growth, endogenous growth, and ecological-economics viewpoints. Our empirical results show the existence of a cointegrating relationship between the different variables investigated. In addition, all the inputs (conventional and non-conventional Granger cause economic growth in both the short and long runs. Our findings confirm the energy-led growth hypothesis in the case of Saudi Arabia. Hence, energy conservation policies may deteriorate economic growth in Saudi Arabia if they are not followed by measures that improve energy efficiency, energy saving technologies and encourage the investment and use of renewable energy sources such as solar and wind energies that can participate in the attenuation of climate changes.

Full Text Available The expansion of power generation in Saudi Arabia is essential in order to meet the expected growth of its electricity demand. Due to the availability of high solar irradiation, vast rainless area and longtime sun light, Saudi Arabia is one of the most suitable countries to utilize solar energy resources in greater extend. Kingdom has planned to increase the production of solar power in order to meet a considerable share of country’s future energy demand. Numerous installation and research works are going on nowadays in the kingdom in order to attain its targets of solar power capacity in the coming years. Hence latest updates of country’s solar industry are essential for further research and R&D works in this field. Saudi Arabia’s current status and future possibility of solar industry are discussed in this paper.

Human brucellosis is an important zoonotic disease and is especially concerning in the Kingdom of Saudi Arabia (KSA), where livestock importation is significant. We analyzed reported human brucellosis disease trends in KSA over time to help policymakers understand the magnitude of the disease and guide the design of prevention and control measures. By using data from the national registry from 2004 to 2012, we calculated the cumulative numbers by age group and months. Trends of incidence rates (IRs) by gender, nationality, and region were also calculated. We found that there was a greater number of cases (19,130) in the 15-44years age group than in any other age group. The IRs significantly decreased from 22.9 in 2004 [95% confidence interval (CI)=22.3, 23.5] to 12.5 in 2012 (95% CI=12.1, 13). Males had a significantly greater IR than females. Most cases were reported during spring and summer seasons. The IR of Saudi citizens was significantly greater than that of non-Saudis, but this difference reduced over time. The IRs of Al-Qassim, Aseer, and Hail were in the highest 25th percentile. Young, male Saudi citizens living in highly endemic areas were at greatest risk of acquiring brucellosis. We recommend vaccinating susceptible animals against brucellosis and increasing the public's awareness of preventive measures. PMID:26429071
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 litigation. (author)

Teucrium (Lamiaceae) is a large and polymorphic genus distributed mainly in Europe, North Africa and in the temperate parts of Asia. In this study, the anatomical features of the leaf and stem of Teucrium polium are investigated. Teucrium has 19 taxa in Iran, which mainly grow in the Irano-Turanian region between 700 and 2000 m above sea level. T. polium belonging to sect. Polium, is a perennial herb growing on Lorestan province. The leaves clearly exhibit xeromorphy due to features such as thick cuticle layer, thick outer epidermal cell wall, high density of trichomes and thick palisade layer of the mesophyll. Anatomical studies on T. polium revealed that the stem shares the general characteristics of the Labiatae family. The aim of our approach was to study the morphological and taxonomical parameters for T. polium in Saudi Arabia. The results of this study showed that there was no influence of environment on the structure of stomata and trichomes as studying species with T . polium. In conclusion our study shows we have studied the geographical distribution of the species in Saudi Arabia and in the world. PMID:25737650

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).
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)

Annual rainfall records of 20 stations for 30 years are used in order to detect rainfall regimes and climatic features of Saudi Arabia using harmonic analysis techniques. In this study, the percentages of variance, amplitudes, and phase angles are calculated in order to depict the spatial and temporal characteristics of the country's rainfall. The first harmonic explains 42 % of rainfall variation in the western (W) region. This percentage increases toward east (E) and north (N) with 69 and 67 %, respectively. In the southwest (SW) region, the percentages explain 43 % of rainfall variation. The percentages of variance in W and SW are lower than in the E, NW, and central (C) regions. This implies significant contributions of the second harmonic in W and SW regions with 26 and 16 %, respectively. The high percentages of the second and third harmonics in W and SW regions suggest that these two regions are affected by different weather systems at different times. The SW region has the highest amplitudes of the first, second, and third harmonics. The amplitude of the first harmonic reaches to 21 mm in SW and 9 mm in both C and E regions. The time of maximum rainfall is calculated using phase angle; the result reflects that maximum rainfall is shifted forward on the time axis toward the spring season in SW and C regions, January in E and NW regions, and October and November in the W region. This reveals that the SW region is a completely different climatic region, though some of what affects this region also affects the central region. Conditions in the E and NW regions are mainly affected by Mediterranean weather systems, while the W region is affected by unstable conditions caused by the active Red Sea Trough (RST) in October and November.
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 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.

Full Text Available Innovation and entrepreneurship are critical elements in the transition to the knowledge-based economy and future competition. Unfortunately, innovation tends to be absent in Arab states for many reasons. To promote innovation in Saudi Arabia, for instance, it is necessary to support inventors’ ideas to turn inventions into start-up companies, which are companies in their early stage. At the same time, it seems that there is a need for more academic research to study the success factors of Saudi information and communication technology (ICT start-up companies. ICT start-ups are important to the economy because they are needed for the progress of all industries. Therefore, this study will identify the factors that lead to successful ICT start-up projects. Then, it will develop a model for the best practices in the interplay among the defined factors that will increase the opportunity to initiate successful start-ups. This research involves a factor analysis study based on a quantitative method to measure the interdependences among the success factors for ICT start-ups. The identified factors are verified using a sample of Saudi start-up companies. The study will contribute to enhancing the technological content to diversify the Saudi economy in order to prepare for the post-oil era. The study result is a survivability model for Saudi-incubated ICT startups. The resulting model has two phases, as follows: (1 the incubation period, which includes the relationships among three factors leading to constant and successful updates and upgrades of the ICT startup business model; and (2 the postincubation period, which include relationships among the three factors that help to deal with the changing nature of the market and the emergence of competing products. This solution can be applied within startups with similar conditions.

The modern economy of Saudi Arabia depends primarily on oil exports. Oil being the source of most of the country's exports, foreign exchange, and government revenues, it follows that the oil sector affects the economy rather than the economy affecting the oil sector. Saudi Arabia lacks natural resources for most of its essential goods and because of sudden high income, it has become necessary to introduce new strategies for producing necessary goods and services. Since Saudi Arabia depends mo...

Objective was to determine the prevalence of type 1 diabetes mellitus among 0-19 years old Saudi children and adolescents. A nationwide Saudi Arabian project was conducted in the years 2001-2007 with the objective of establishing national growth charts and defining the prevalence of some chronic childhood diseases such as diabetes mellitus. The 14000 households were randomly selected based on a recent population statistic. The questionnaire used included demographic data and evidence of diabetes mellitus. The prevalence was estimated and expressed per 100,000. Breakdown of this figure per age and region was carried out. In the 11,874 out of the 14000 (84.9%) selected households, 45,682 children and adolescents were surveyed. Fifty children and adolescents were identified to have type 1 diabetes mellitus with a prevalence rate of 109.5 per 100,000. The male to female ratio was almost equal (26 males and 24 females). The distribution of prevalence of type 1 diabetes mellitus by region shows that the highest was 162 in the central region. Children and adolescents were also grouped by age into 5-6 (prevalence 100), 7-12 (prevalence 109), 13-16 (prevalence 243) and 17-18 (prevalence 150). We conclude that the prevalence of type 1 diabetes mellitus in Saudi Arabian children and adolescents is 109.5 per 100,000. (author)

Objective was to determine the prevalence and regional distribution ofsickle cell disease in Saudi children. A sample size of 45,682 children andadolescents from newborn to 19 years of age was selected by multistage randomprobability sampling of the Saudi households from each of the 13 regions ofthe country. The study is cross-sectional, community based and conducted over2 years from 2004 to 2005. Data including history and clinical examinationwere collected with house-to-house survey of all selected households. Datamanagement and analysis was carried out at King Saud University, Riyadh,Saudi Arabia. Sickle cell disease was detected in 108 of 45,682 children andadolescents with a prevalence of 24 per 10,000. The regional distribution ofsickle cell disease showed eastern region dominance with a prevalence of 145per 10,000, followed by the southern region with a prevalence of 24 per10,000, western region 12 per 10,000and central region with 6 per 10,000. Nocases were found in the northern region. The male to female ratio wasapproximately 1:1. The results of this national wide community-based surveyshow a high prevalence of sickle cell disease. In the community and thedisease is more common in eastern and southern regions of the country.National or regional newborn screening programs for sickle cell disease usinghematological tests should be planned. This study shows that the populationat risk has an uneven geographical distribution. For this reason, selectiverather than universal neonatal screening is likely to be more appropriate inthe country.

Full Text Available This article examines the Kingdom of Saudi Arabia's gender-segregated higher education system and how it is used to transmit the Kingdom's traditional societal expectations to the employment sector. With Saudi Arabia's current need for economic change, the education system is retarding instead of accelerating reform. A background consisting of Saudi Arabian history, governing laws, religious beliefs and women's roles is examined. I then discuss the education system's preservation goal by considering segregation, women's mobility, videoconferencing courses, and the roles of professors. I attempt to explain how the current education system fails to prepare its students for the global economy: by limiting women's access to the labor market, and by not preparing men for the realities of the global market and therefore creating the need for migrant workers. In conclusion, conserving culture is significant, but for economic change to occur, the extent of cultural conservatism and its effect on the education system need to be re-evaluated.

Full Text Available This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the exclusion method (ex food and housing/rent and the statistical method. The findings of the analysis suggest that the ex food and housing/ rent inflation is more volatile than the overall CPI inflation over the sample period. In contrast, the statistical core inflation is relatively more stable and less volatile. Moreover, the ex food and housing/rent inflation is only weakly correlated with headline inflation, whereas the statistical core inflation exhibits a stronger correlation. This combination of lower volatility and higher correlation with headline inflation makes the statistical method a much better choice for policymakers. From a monetary policy standpoint, using a bundle of core inflation measures, including both properly constructed exclusion and statistical methods, is more desirable, especially when variation across measures is widespread, as is the case in Saudi Arabia.

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

This paper describes perceptions of familiarity with symptoms and beliefs about illnesses based on interviews with 50 Saudi women. The sample was young, with 82% under the age of 40, and not well educated by Western standards, with one-third being illiterate and 80% having no more than a primary school education. More than half lived in households of six or more. Although there was greater awareness of germs as causative factors in illness than previous studies in Saudi Arabia had demonstrated, beliefs in multiple causes, including religious beliefs about disease causation, persisted. There was an apparent lack of understanding of specific causes of various illnesses or of the rationale for preventive measures. This lack of understanding may be related to the low education levels and/or deeply ingrained cultural beliefs. PMID:1475998

Full Text Available To provide a universal basic education, Saudi Arabia initially employed a rapid quantitative educational strategy, later developing a qualitative focus to improve standards of education delivery and quality of student outcomes. Despite generous resources provided for education, however, there is no national assessment system to provide statistical evidence on students’ learning outcomes. Educators are querying the curricula and quality of delivery for Saudi education, especially following low student performances on the Trends in International Mathematics and Science Study (TIMSS in 2003 and 2007. There is a growing demand for national assessment standards for all key subject areas to monitor students’ learning progress. This study acknowledges extant research on this important topic and offers a strategy of national assessment to guide educational reform.
On Aug. 2, 1990, Iraqi forces invaded Kuwait and triggered one of the most severe crises in the world's oil supplies since World War II. Within a few days of the invasion, Iraqi and Kuwaiti oil exports were embargoed, and almost 4.6 million b/d oil of production was removed from world markets. This shortfall amounted to about 20% of total Organization of Petroleum Exporting Countries production at the time and could have proven disastrous to the world's industrial and financial well-being. However, there was no disruption to the major economies of the world. This paper reports that the primary reason for the cushioning of this impact was the massive expansion in production undertaken by Saudi Arabian Oil Co. (Saudi Aramco)
The argument for and against the application of peaceful nuclear energy in Saudi Arabia is discussed in terms of the country's industrial development and power requirement for electricity and desalination. The discussion leads to the conclusion that due to its large oil reserve, Saudi Arabia may tolerate a considerate approach to nuclear energy up to the year 2000. Beyond this date, nuclear energy should be used in order to achieve the desired industrial maturity in the country. The introduction of nuclear energy, however, will be faced with three constraints, namely man power availability, cooling water requirement, and the size of the electrical grid. The period 1980-2000 is thus most suitable for important preparation steps, among which are the adoption of regulatory provisions, establishment of nuclear facilities with necessary equipments, and staff training for regulatory, organizational, and technical activities. The paper outlines a scheme for the initiation steps and efforts to meet these requirements. (orig.)

A review of the literature on successful implementation of ERP reveals that there are many case studies undertaken by researches, but very few have empirically examined the success factors of ERP implementation. While most of those empirical studies were undertaken in Western countries, very few had examined the implementations in Middle Eastern countries and none in Saudi Arabia. Factors and challenges of ERP implementation in developing countries differ from those of Western countries. Henc...

Innovation and entrepreneurship are critical elements in the transition to the knowledge-based economy and future competition. Unfortunately, innovation tends to be absent in Arab states for many reasons. To promote innovation in Saudi Arabia, for instance, it is necessary to support inventors’ ideas to turn inventions into start-up companies, which are companies in their early stage. At the same time, it seems that there is a need for more academic research to study the success f...

This paper reports on updating two important Saudi Arabian crude oils-Arabian Heavy (Safaniya) and Arabian Light-which is part of a continuing series on world export crudes. Arabian Heavy (Safaniya) was reassayed in early 1990; Arabian Light in May 1990. These assays, therefore, replace those that appeared previously. However, as is frequently the case with crudes from major, single reservoirs, there is little, if any, change in their characteristics

OBJECTIVE: Assessing the knowledge and awareness of the Saudi society about bronchial asthma in children. METHODS: Structured questionnaires were randomly distributed to 1039 Saudi Arabians in May 2014 at Jeddah, Riyadh, and Dammam. RESULTS: The awareness of bronchial asthma questions showed that 67% of total sample thought that it could be a fatal disease, and only 13.2% thought that there is a difference between bronchial asthma and chest allergies in children. 86.1% thought that the symptoms of bronchial asthma include dyspnea and nocturnal cough, and 45.7% thought that fever, a runny nose and throat inflammation are not symptoms. 60.2% thought that infectious respiratory diseases may increase bronchial asthma progression. In addition, 40% thought that the use of antibiotics doesn’t help in diminishing bronchial asthma complications, and some thought that the patient can stop medication after an acute asthma attack. 34.1% thought that inhaled medication for asthma doesn’t cause addiction. Very highly significant results are shown between bronchial asthma knowledge and age, the level of education, marital status, and if the individual knows a person who suffers from bronchial asthma (P < 0.001). There are positive correlations between bronchial asthma knowledge and age, marital status, and level of education (r = 0.152, 0.150, 0.197), respectively. CONCLUSION: The study demonstrated that bronchial asthma knowledge in the Saudi Arabian population is insufficient, and efforts should be carried out to spread bronchial asthma management.

To investigate the knowledge, attitude, and practice of health care professionals on the early detection of breast cancer. A cross-sectional study was conducted in Jeddah and Abha regions of Saudi Arabia from May to November 2009. A detailed questionnaire was distributed to 500 doctors from different hospitals. The questionnaire contained items on the practice of clinical breast examination and mammogram examination, and the doctor's perception of their roles in education. The results of 337 questionnaires analyzed indicated that most health care professionals do not practice clinical breast examination and mammography, and the perception of their roles in education is not as expected. Health care providers are one of the main barriers in improving early detection of breast cancer in Saudi Arabia. There is a need to increase awareness among health care providers of their role in the fight against breast cancer through focused education and training programs (Author).

Global energy scenario is changing drastically toward decline, as new major discoveries of fossil fuel are not coming up significantly on regional basis. In case of Saudi Arabia, one of the largest fossil fuel producers, the major oil fields have started exhausting significantly as revealed from the literature research study. Considering the future energy crisis, different other renewable options presently have became imperative to be consider anticipating for the national development. Wind energy in one of them. The development of wind energy technology requires the baseline data relevant to the wind trends and their potentials. Under the present study, an attempt has been made to develop wind power density map of the Makkah Province of Saudi Arabia based on the meteorological data collected at different sparsely located weather stations. GIS application has provided a good option to interpolate the gap areas between the sparsely located weather recording stations. This paper describe the methodology and results of the present study.

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.

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.

[Purpose] To explore the views of the physical therapy service leaders in Saudi Arabia regarding the integration of physical therapy service in primary health care settings. [Subjects and Methods] A self-administered questionnaire consisting of both open and closed ended questions was distributed during May–July 2013 via email to physical therapy leaders representing different regions and health care providers in Saudi Arabia. [Results] Twenty-six participants answered the questionnaire. Eighty five percent of the sample had ≥ 10 years of experience with 57.6% of them holding a post-graduate degree. Participants were from different health care providers and represented different geographical regions of Saudi Arabia. Eighty one percent of the sample reported that the adoption of physical therapy services in primary health care would be advantageous, as it would offer earlier access to health care and would be more cost-effective. The respondents also stated that such a service would contribute towards the prevention of common non-communicable health diseases. [Conclusion] The results of this survey provide generally positive recommendations for the provision of physical therapy service in Saudi Arabia primary health care centers. However, challenges and barriers identified by this study require consideration during the development of the service. PMID:26957740
The Saudi Cabinet of Ministers approved the Saudi General Environment System (SGES) in 2001. This approval is considered a step forward towards preserving the environment in Saudi Arabia. One of the targets of this system is to make environmental planning as an un-replaceable part of every comprehensive development planning in all industrial, agricultural, and architectural sectors. Achieving such a target requires a specialized labor force. Therefore, College of Engineering should act positively and actively in disseminating environmental awareness among engineers since they play a major rule in development projects. A degree in environmental engineering is a must at present, which is not available yet at any university in Saudi Arabia. Details of a B. Sc degree in environmental engineering offered by two universities in USA, are discussed. The syllabus of a degree in environment engineering adapted for the Saudi environment and culture is outlined
Full Text Available Education remains one of the most important economic development indicators in Saudi Arabia. This is evident in the continuous priority of the development and enhancement of education. The application of technology is crucial to the growth and improvement of the educational system in Saudi Arabia. Introducing SMART Table technology in the Saudi Arabian education system is argued in this paper as being able to assist teachers and students in the process of accommodating both technological changes and new knowledge. SMART Tables also can enhance the level of flexibility in the educational system, thus improving the quality of education within a modern Saudi Arabia. It is crucial to integrate technology effectively and efficiently within the educational system to improve the quality of student outcomes. This study will consider the potential benefits and recommendations associated with the adoption of SMART Tables in Saudi Arabian education system.
Saudi Arabia this year is completing its expansion of production capacity and developing recent discoveries to enhance export flexibility. The 3 million b/d capacity expansion to 10 million b/d, announced in 1989, is on target for completion by year end 1994. Most of the effort involves restoration of mothballed production equipment and installation of several gas-oil separation plants (GOSPs) in existing fields. But Saudi Arabian Oil Co. (Saudi Aramco) also this year will start up production of extra-light oil from a new field in the central part of the kingdom. Start-up of Hawtah area production demonstrates success of an oil search Aramco began after receiving exclusive exploration rights to nearly all of Saudi Arabia's prospective area in 1986. From new fields and traditional producing areas, therefore, Saudi Arabia has the potential to expand production capacity beyond 10 million b/d. The paper describes the development of the extra capacity
Shifts in Saudi Arabian oil policy are explained by using data covering public revenues and expenditures plus the balance of payments. It is concluded that, according to the target revenue theory, Saudi Arabia only for a very short time after the first and second oil crises was on the backward sloping part of the supply curve. Perhaps Saudi Arabia cut oil production during the two oil crises because it wanted big oil price increases to prevent budget cuts. In any case, it started to increase oil production in the middle of 1985 when its economy was in great imbalance. Furthermore, calculations for the period 1989-2000 reveal that Saudi Arabia will probably face economic problems in the 1990s so that it will not again be OPEC's swing producer. On the contrary, Saudi Arabia will probably increase its share of OPEC's oil production in the 1990s. (author)

The aim of this study was to investigate the attitudes and use of complementary and alternative medicine (CAM) among Saudi Arabian adolescents. A multistage stratified sampling method was used to select 736 adolescents (358 males, 378 females) aged 15-19 years from secondary schools. The study was carried out in Al-Khobar city, Eastern region of Saudi Arabia. The findings revealed that the use of CAM by adolescents in their lifetime ranged from 1.6% for acupuncture to 58.6% for honey treatment, with significant differences between genders, except in the use of dietary supplements, black cumin, and acupuncture therapies. Females were more likely to use CAM for treating abdominal pains, cold and flu, and cough than males (P < 0.000). Family members and friends (67.7%) were the main source of CAM usage, followed by television (10%), and Internet (8%). Religious and medicinal herb healers were the CAM healers most commonly visited by adolescents. Nearly 21-43% of adolescents had positive attitudes toward CAM, with some significant differences between males and females. It can be concluded that CAM is widely used by Saudi adolescents, but caution should be exercised for the safe usage of some CAM treatments. CAM should not be ignored; however there is an urgent need to establish regulations for CAM usage. PMID:25560362
Schistosomiasis is caused by infection with the parasite Schistosoma, which is a flat-worm or fluke. The dominant species are Schistosoma mansoni, Schistosoma japonicum, and Schistosoma haematobium. Schistosomiasis is the third most common parasitic disease in the world after malaria and amoebiasis. It is endemic in more than 70 countries affecting about 200 million people worldwide, of whom 80% are in sub-Saharan Africa. There are pockets of infection in north-eastern Brazil, near the Yangtze River in China, and some pockets in south East Asia. In the East Mediterranean regions, the Schistosoma have been reported in Iraq and Egypt as well as in Sudan. The latter has the highest infection rate nowadays, particularly in the Al Jazeera area, due to the poor Schistosoma control program. In the Arabian peninsula, schistosomiasis has been reported in southwest part of Saudi Arabia, mainly in the Asir province and Jizan province, which lay in the southwest corner of Saudi Arabia and directly north of the border with Yemen. The efforts to control schistosomiasis have been very successful in Saudi Arabia due to the irrigation system control. However, the infection is prone in Yemen, where the schistosomiasis control is much less strict. Thus as a result, the problem still exists due to transmigration of the populations from both countries. As a cause of pulmonary arterial hypertension (PAH), schistosomiasis is still under diagnosed and undertreated. This article with give a highlight about the pathophysiology of the disease and both diagnostic and therapeutic strategies. PMID:25076995

Saudi Arabia has a rich architectural heritage that can be found in all regions of the vast country. Except for a small number of publications the recording and documentation of the traditional built environment was not content of detailed scientific investigations so far. But with the increasing decay of the architectural heritage the interest for this kind of research is rising. A mirror of this efforts is the National Built Heritage Forum, annual conference, launched in 2010 by his excellency Prince Sultan bin Salman bin Abdulaziz Al Saud and the Saudi Commission for Tourism and Antiquities (SCTA). In that frame Saudi universities are intensifying research and educational programs for the research of traditional architecture. In 2008 the Department of Architecture of the College of Environmental Design at the King Abdulaziz University established a cooperation with the Department of History of Architecture and Building Archaeology of the Vienna University of Technology with the aim to start an exchange of knowledge and experience in building archaeology and building survey. An important part of this cooperation was a workshop for staff and students in the historic centre of Jeddah. The aim was to train methods and techniques on typical examples in the old town of Jeddah, Al Balad. This paper is describing the layout of the workshop, the process of the work and examples of the results.

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

Current investigations of the motions of the Arabian and its neighboring plates are primarily based on GPS measurements obtained in the surrounding areas of the Arabian plate, with few stations actually located on the Arabian plate itself in the Kingdom of Saudi Arabia. In order to advance the knowledge of the dynamics of the Arabian plate and its intra-plate deformations, the General Directorate of Military Survey (GDMS), through collaboration with the Institute of Engineering Surveying and Space Geodesy (IESSG), densified the GPS network in Saudi Arabia, covering nearly two thirds of the tectonic plate. Since July 2002, a network of 32 GPS stations has been established at locations of the Saudi Arabia geodetic network. At all of these GPS stations a concrete pillar has been used as the monument and the locations have been selected in order to give the broadest distribution of observing sites. During 2005, 27 additional GPS stations in the Hejaz and Asser Mountains, and the Farasan Islands, all in south-western Saudi Arabia, have been established, for which the past and future campaign GPS measurements will provide valuable data for investigations of crustal deformations close to the plate boundaries between the Nubia, Somalian and Arabian plates. In this presentation we will show results in the form of velocity field and plate motion estimates based on data from at least three campaigns occupying the initial 32 GDMS GPS network stations, but also from a number of IGS stations in the region. Our reference frame is aligned to ITRF2005 and uses approximately 40 IGS reference frame stations located on all major tectonic plates, e.g. Nubia and Somalia, surrounding the Arabian plate. Furthermore, we apply absolute satellite and receiver antenna phase center models together with newly available GPS products from a recent global re-processing effort.

Full Text Available Background: Diabetes imposes a large economic burden on the individual, national healthcare systems, and countries. Objective: To determine the economic impact of diabetes mellitus on Saudi healthcare system, both now and in the future. Materials and Methods: This research study uses a prevalence-based approach that combines the demographics of the population (classified by nationality, sex and age group with and without diagnosed diabetes in 1992 and 2010. The economic impact of diabetes is estimated in this study, using secondary sources of information provided by Ministry of Health, Ministry of Finance and Central Department of Statistics and Information databases. Results: People diagnosed with diabetes, on average, have medical healthcare expenditures that are ten times higher ($3,686 vs. $380 than what expenditures would be in the absence of diabetes. Over 96% of all medical healthcare expenditures attributed to diabetes are incurred by persons of Saudi nationality, with the remaining 4% incurred by persons of non-Saudi nationality. The population age 45-60 incurs 45% of diabetes-attributed costs, with the remaining population under age 15 incurs 3.8%, age 15-44 incurs 27.5%, and age 60 and above incurs 23.8%. Conclusion: The actual national healthcare burden because of diabetes is likely to exceed the $0.87 billion estimated in this study, because it omits the indirect costs associated with diabetes, such as absenteeism, lost productivity from disease-related absenteeism, unemployment from disease-related disability, lost productivity due to early mortality by disease. The social cost of intangibles such as pain and suffering and care provided by non-paid caregivers as well as healthcare system administrative costs, cost of medications, clinician training programs, and research and infrastructure development is also omitted from this research study. Further studies are needed to confirm the present findings and to improve our
Full Text Available Communication has a major impact on how customers perceive sellers and their organizations. Especially, the non-verbal communication such as body language, appearance, facial expressions, gestures, proximity, posture, eye contact that can influence positively or negatively the first impression of customers and their experiences in stores. Salespeople in many countries, especially the developing ones, are just telling about their companies’ products because they are unaware of the real role of sellers and the importance of non-verbal communication. In Saudi Arabia, the seller profession has been exclusively for foreign labor until 2006. It is very recently that Saudi workforce enters to the retailing sector as sellers. The non-verbal communication of those sellers has never been evaluated from consumer’s point of view. Therefore, the aim of this paper is to explore the non-verbal communication barriers that customers are facing when dealing with Saudi sellers. After discussing the non-verbal communication skills that sellers must have in the light of the previous academic research and the depth interviews with seven focus groups of Saudi customers, this study found that the Saudi customers were not totally satisfied with the current non-verbal communication skills of Saudi sellers. Therefore, it is strongly recommended to develop the non-verbal communication skills of Saudi sellers by intensive trainings, to distinguish more the appearance of their sellers, especially the female ones, to focus on the time of intervention as well as the proximity to customers.

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

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.)
Full Text Available This study covers various aspects of the aerosol distribution and characteristics, namely, optical depth climatology, absorption characteristics, and their microphysical properties over four regions in Saudi Arabia using satellite and ground observations including MODIS/Terra and Aqua, OMI, MISR/Terra, AERONET, and CALIPSO for the period April 2003–January 2013. The study includes cities in the North Western, Western, Eastern provinces of Saudi Arabia and in the Rub al Khali desert or Empty Quarter. Satellite and ground observations showed that the dust season extends from April to August with prominent peaks yet with high anthropogenic contribution late summer and early fall. Analysis shows an increase in the aerosol concentration during March 2009 which could be attributed to a major dust storm during that time. Comparing the AOD time series over regions 1–3 and region 4 (desert we observe monthly and annual variability with no recurrence pattern over the years. The Aqua Deep Blue AOD550 data shows a single peak pattern that occurs over region 4 during the spring season known for its frequent dust events. OMI data shed the light on the presence of higher air pollution levels over region 3, representing the oil rich eastern province of Saudi Arabia.

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 spending time alone or with family and friends. (author)

Full Text Available This is a study performed to identify the risk factors for gallstones in Saudis, taking the patient population of King Khalid University Hospital as a sample. Only Saudis with symptomatic gallstones were studied, the parameters being age, sex, weight, body mass index, fertility, age at menarche and age at marriage. The results showed that sex, weight, body mass index and fertility all appeared to be important factors in the development of gallstones and that the condition affects more Saudi females and at a younger age than reported in the literature, probably due to overweight and factors related to reproductivity. We conclude that gallstones are common in Saudi women and affect them at a younger age than western women, weight and fertility appear to be important risk factors.
Full Text Available Abstract Background Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national guidelines for minimal acceptable competencies of a medical graduate. Discussion We are arguing for the need for a Saudi national medical licensing examination that consists of two parts: Part I (Written which tests the basic science and clinical knowledge and Part II (Objective Structured Clinical Examination which tests the clinical skills and attitudes. We propose this examination to be mandated as a licensure requirement for practicing medicine in Saudi Arabia. Conclusion The driving and hindering forces as well as the strengths and weaknesses of implementing the licensing examination are discussed in details in this debate.

The biomedical research sector in Saudi Arabia has recently received special attention from the government, which is currently supporting research aimed at improving the understanding and treatment of common diseases afflicting Saudi Arabian society. To build capacity for research and training, a number of centres of excellence were established in different areas of the country. Among these, is the Centre of Excellence in Genomic Medicine Research (CEGMR) at King Abdulaziz University, Jeddah, with its internationally ranked and highly productive team performing translational research in the area of individualized medicine. Here, we present a panorama of the recent trends in different areas of biomedical research in Saudi Arabia drawing from our vision of where genomics will have maximal impact in the Kingdom of Saudi Arabia. We describe advances in a number of research areas including; congenital malformations, infertility, consanguinity and pre-implantation genetic diagnosis, cancer and genomic classifications in Saudi Arabia, epigenetic explanations of idiopathic disease, and pharmacogenomics and personalized medicine. We conclude that CEGMR will continue to play a pivotal role in advances in the field of genomics and research in this area is facing a number of challenges including generating high quality control data from Saudi population and policies for using these data need to comply with the international set up.

The technology of drilling and production of horizontal wells is probably one of the most significant breakthrough in the oil and gas industry of the eighties. The continuous improvement of hardware equipment made horizontal drilling cost-effective technique for developing reserves, improving productivity and recovery in oil and gas reservoir. This paper is devoted to Saudi experience in horizontal drilling. The last years have been an exciting period for those who believed in horizontal drilling applicability in Saudi Arabia. At the end of the year 1997 more than 150 horizontal wells have been drilled in Saudi oil fields. There are four major horizontal well applications identified in Saudi Arabia oil fields; 1) Control of coning in relatively thin remaining all column area, 2) Improving sweep efficiency of water flooding program. 3) Improving productivity rate in thin/tight reservoirs and 4) Saving in total development costs in conjunction with previous three applications. This paper presents the major areas of application of horizontal well and more specifically the objectives of applying horizontal drilling in different Saudi oil fields and the world horizontal drilling activities along with the Saudi experience will be convered. This paper surveys different field examples to show the application trends of horizontal well technology in both offshore and onshore oil fields. The main objective of this survey is to demonstrate the performance improvement of these oil fields after the application of horizontal well technology. (author)

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.

With 266 billion barrels of proved oil reserves (16% of world total), Saudi Arabia holds the world's largest (conventional) crude oil reserves, was the largest exporter of total petroleum liquids in 2013, and the second largest petroleum liquids producer behind the United States. The Kingdom has the lion share of the global oil production spare capacity, which proved to be crucial for the oil market stability on many occasions in the past, allowing Saudi Arabia to replace missing barrels from any other oil producer in the world. In the same manner, Saudi Arabia's decision last November not to step-in and reverse the oil price decline thus, abandoning its historical role as a 'swing producer,' revived the old debate on the use of oil as a 'political weapon' on the international energy scene. In addition to its well-known predominant role in the oil markets and in the Organisation of Petroleum Exporting Countries (OPEC), several other features make the Kingdom of Saudi Arabia a major player in the world economy and global geopolitics. - Although the Kingdom does not export nor import natural gas, Saudi Arabia is embodied with the 5. natural gas proved reserves (8.2 trillion cubic meters (tcm), 4.4% of world natural gas proved reserves), behind Russia, Iran, Qatar and United States. With a production of 103 billion cubic meters (bcm), Saudi Arabia is also a gas producer solely for its domestic demand. - Because the Kingdom relies heavily on hydrocarbons for its present and future prosperity, the country is very active in climate change negotiations, as mitigation measures resulting from such negotiations will impact global oil demand. In the international talks on climate change, Saudi Arabia has often been calling for the need to address the vulnerabilities of the economies dependent on a single resource. - The Kingdom of Saudi Arabia is member of G20 Group, putting up-front oil producers' interests in a forum which accounts for 85

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.

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 study argues that ideological rather than material constraints are the major obstacles that limit full female participation in the Saudi Arabian labour force and hinder Saudi working women from combining their double roles as mothers and paid workers. As a developing country, Saudi Arabia is facing multiple problems. One of these challenges is the great shortage of human resources. In 1984/85, 59.8 per cent of the labour force in Saudi society was foreign. Female ...

Saudi student enrollment in U.S. colleges and universities has nearly tripled since 2009-2010, in large part due to the King Abdullah Scholarship Program. The representation of Saudi females is also increasing due to the loosening of Saudi Arabia's long-standing restrictions on women's travel and acceptable fields of study and careers. This…

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

Model. The empirical models then are applied to sets of data from 1980 to 2002 for Saudi Arabia, Kuwait, Venezuela and Norway. The rationale of including other oil-exporting countries is to distinguish whether the shocks are country-specific, regional-specific, or global. Two sets of shocks are considered: international shocks and domestic shocks. Three types of international shocks are chosen: commodity-price (oil price) shock, international financial (interest rate) shock, and international real (output) shock. In addition, five domestic shocks which are non-oil output shock, oil production shock, price level shock, monetary shock, and exchange rate shock. The findings reached in the study demonstrate that the international shocks are responsible for a high proportion of fluctuations in the economic activity in Saudi Arabia. Most importantly, the international financial shocks represented by the US interest rate and oil price shocks are the major sources of fluctuations in the Saudi Arabian economy. Domestically, the economy is mostly affected by the oil production and the non-oil output shocks for Saudi Arabia. These results emphasize that the Saudi Arabia's role in the international oil market and its fixed exchange rate regime have significant implications on the domestic economy. Thus, special considerations should be placed on designing the appropriate policies to lessen the dependency on the oil sector and strengthen the role of private sector to diversify the economic base, and provide an independent sound monetary policy to steer the economy from the fluctuations in the global economy.

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.

We investigate the lithospheric shear-wave velocity structure of Saudi Arabia by conducting H-κ stacking analysis and jointly inverting teleseismic P-receiver functions and fundamental-mode Rayleigh wave group velocities at 56 broadband stations deployed by the Saudi Geological Survey (SGS). The study region, the Arabian plate, is traditionally divided into the western Arabian shield and the eastern Arabian platform: The Arabian shield itself is a complicated mélange of crustal material, composed of several Proterozoic terrains separated by ophiolite-bearing suture zones and dotted by outcropping Cenozoic volcanic rocks (locally known as harrats). The Arabian platform is primarily covered by 8 to 10 km of Paleozoic, Mesozoic and Cenozoic sedimentary rocks. Our results reveal high Vp/Vs ratios in the region of Harrat Lunayyir, which are interpreted as solidified magma intrusions from old magmatic episodes in the shield. Our results also indicate slow velocities and large upper mantle lid temperatures below the southern and northern tips of the Arabian shield, when compared with the values obtained for the central shield. We argue that our inferred patterns of lid velocity and temperature are due to heating by thermal conduction from the Afar plume (and, possibly, the Jordan plume), and that volcanism in western Arabia may result from small-scale adiabatic ascent of magma diapirs.

Life in arid regions and, in particular, hot deserts is often limited due to their harsh environmental conditions, such as large temperature fluctuations and low amounts of water. These extreme environments can influence the microbial community present on the surface sands and any rhizosphere members surrounding desert plant roots. The Jizan desert area, located in Saudi Arabia, supports particular vegetation that grows in the large sandy flat terrain. We examined five different samples, four from the rhizosphere of pioneer plants plus a surface sand sample, and used pyrosequencing of PCR-amplified V1-V3 regions of 16S rDNA genes from total extracted DNA to reveal and compare the bacterial population diversity of the samples. The results showed a total of 3,530 OTUs in the five samples, calculated using ≥ 97% sequence similarity levels. The Chao1 estimation of the bacterial diversity fluctuated from 637 to 2,026 OTUs for a given sample. The most abundant members found in the samples belong to the Bacteroidetes, Firmicutes and Proteobacteria phyla. This work shows that the Jizan desert area of Saudi Arabia can contain a diverse bacterial community on the sand and surrounding the roots of pioneer desert plants. It also shows that desert sand microbiomes can vary depending on conditions, with broad implications for sandstone monument bacterial communities

The development of the dairy industry plays an important role in the economy of Middle Eastern countries. Judged by its growth rate, the dairy industry is viewed as one of the most progressive food industries in the Middle East. During the early 1970s, countries established executive programs to promote dairy farming; the major objective was to attain self-sufficiency in milk production. A massive investment was set up for importing top class cattle, complying with top industry operating standards, and a simultaneous introduction of the latest technology in processing, packaging, and distributing. Milk production has grown tremendously at rates of 6.6% and 4.9% in Syria and Saudi Arabia, respectively, between 2002 and 2007, which resulted in these nations being almost self-sufficient. Regarding Jordan, milk production has not yet met this target. An excessive growth in the dairy industry is quite noticeable in this region with an expanding capacity for exports. The aim of this study is to show the most recent trends and future prospects of the dairy industries in Syria, Saudi Arabia, and Jordan. It also attempts to investigate the drivers for the development of milk production, consumption, and trade in the region. PMID:20352329
The Al-Hassa area is one of the regions in Saudi Arabia where hemoglobinopathies are prevalent. The Saudi Ministry of Health designed a protocol for premarital testing after the royal decree in December 2003. The protocol was implemented in a February 2004 order. The aim of this study was to determine the prevalence of beta-thalassemia trait among subjects coming for premarital screening in the Al-Hassa area. From February 2004 to November 2004, healthy subjects coming to six marriages consultation centers in the Al-Hassa area underwent routine mandatory tests. Subjects were considered to have beta-thalassemia trait if they had a mean corpuscular volume (MCV), 80 fL and/or a mean corpuscular hemoglobin (MCH) 3.2%. Venous blood was taken into ETDA tube and the complete blood count and red blood cell indices were measured by a Coulter automated cell counter on the same day of hemoglobin collection. Electrophoresis was done on cellulose acetate. All Saudi participants (n=8918), including 4218 (47.3%) males and 4700 (52.7%) females were screened. The prevalence of beta-thalassemia trait with high hemoglobin A2 and microcytic hypochromic anemia was 3.4% (307/8918). In countries with a high prelevance of hemoglobinopathies, a premarital screening program is helpful for identification and prevention of high-risk marriages. With a 3.4% prevalence of beta-thalassemia trait in premarital couples, future comprehensive programs are needed to know the actual prevalence of beta-thalassemia in Al-Hassa. (author)

In order to investigate the diversity of ABO and Rh blood group genes in the Saudi Arabian population, we assembled the phenotypic data of approximately 66,000 subjects from ten representative Saudi populations: Al-Khobar, Riyadh, Tabuk/Madina Al-Munawaara, Jeddah, Abha, South region, Sakaka, Domah, Al-Qurayat, and Sweer. The frequencies of p[A], q[B], and r[O] alleles at the ABO locus were observed to be 0.1688, 0.1242, and 0.7070, respectively, and the frequency of the D allele at the Rh locus was 0.7138. The heterozygosities at the ABO and Rh loci were 0.4563 and 0.4086, respectively, while the combined heterozygosity was 0.4324. Homogeneity tests revealed the population of Abha to be the most heterogeneous while that of Tabuk/Madina was found to be the least heterogeneous. Homogeneity was higher among the Northern populations while Southern populations demonstrated subdivisions and stratification. Gene diversity analyses yielded a total heterozygosity value of 0.4449. The coefficient of gene differentiation was 0.0090. Nei's genetic distance analyses showed that there was close affinity between the populations of Al-Khobar and Riyadh. The largest differences were observed between the populations of Sakaka and Domah. Furthermore, negative correlations were found between p[A] and r[O] alleles, and between q[B] and r[O] alleles at the ABO locus. Clinal analyses revealed that the r[O] allele showed an increasing trend from North-East to South-West, and conversely the q[B] allele exhibited a decreasing trend at these coordinates. These analyses present interesting aspects of the blood group allele distribution across the geography of Saudi Arabia. PMID:26214466

In Saudi Arabia, local interpretations of Islamic laws and social norms have a negative impact on the health and well-being of women. The objective of this literature review was to discuss gender inequity in Saudi Arabia and its relation to public health. Despite the scarcity of recent statistics and information regarding gender inequity in Saudi Arabia, this review is an attempt to explore this sensitive issue in this country. Women's roles and rights in Saudi society were examined, including education, marriage, polygamy, fertility, job opportunities, car driving and identification cards. Further research to assess knowledge, attitudes and practices towards health care of Saudi men and women is recommended. PMID:20214168

Arid countries like Saudi Arabia often depend on fossil groundwater. Hence, thorough studies of the available resources are crucial. In the course of such investigations, analyses of δ18O and δD are frequently applied to constrain the provenance of the waters and to reconstruct the (paleo)climatic conditions during their recharge. Yet, to be able to evaluate the isotopic signature of the groundwater, one also has to know the isotopic composition of current precipitation. Although a few rain water analyses are available for Central Saudi Arabia in the literature - mostly in unpublished consultant reports - a Local Meteoric Water Line has never been established. To complement the available data, 28 rain events occurring in Riyadh between 2009 and 2013 were studied for their stable isotope composition. Samples were collected as integral samples, i.e., they represent the entire precipitation event. Moreover, one event was sampled several times, aiming at an evaluation of intra-storm variability. During selected storms, a grab sample was taken for 3H analysis. The event samples showed δ18O and δD values scattering between -6.5 and +9.5 and between -30 and +50 ‰ V-SMOW, respectively. In the course of the event that was sequentially sampled, a proceeding isotopic depletion was observed with respect to both isotopes. The relatively large ranges of δ-values for 18O and D of approximately 7 and 38 ‰ V-SMOW highlight the general need for integral sampling. The obtained grab samples are characterized by moderate 3H concentrations of a few Tritium Units. Further results will be presented and discussed in view of associated weather data (e.g. rain amount and temperature) and the probable moisture sources derived from back-trajectories, which were calculated using HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory Model; Draxler & Rolph, 2003).

A study was designed to determine the red cell values (hemoglobin and hematocrit) of neonates born in the high altitude of Abha and to compare these values with known values of other lowland areas of Saudi Arabia. From the cord blood of 587 normal, appropriate for gestational age and term infants born in 1993 in Abha Maternity Hospital, the ranges of Hb and Hct were 130 to 240 g/L and 0.24 to 0.79 L/L respectively. The mean Hb was 187 g/L. There was no significant difference between the male and female values. Also, 17% of the infants in this study were polycythemic, while no polycythemia was recorded in these lowland areas and only 2% to 4% in the general global newborn population. It was therefore revealed that Abha newborns had higher red cell values at the birth when compared to other newborns in the low altitude areas of Riyadh and Jeddah (P<0.001). We postulate that high altitude (2700 meters above sea level) of Abha, and therefore its relative hypoxia, has induced high red cell values in infants born in the city. The phenomenon therefore warrants the adoption of higher red cell reference values and not necessarily those already documented in other Saudi new born populations. (author)

Full Text Available Rabies is endemic in animals in the Arabian Peninsula. Although Saudi Arabia is the largest country in the Peninsula, little has been published about the rabies situation in the country. A total of 11 069 animal bites to humans were reported during 2007–2009, and 40 animals suspected of rabies were examined for rabies infection from 2005 through 2010. Results suggest that animal-related injuries in Saudi Arabia remain a public health problem, with feral dogs accounting for the majority of bites to humans and for the majority of animals found to be rabid. Over the last 10 years, no confirmed human rabies case has been reported. More detailed information about the epidemiology of animal bites and that of animal rabies in Saudi Arabia would be of great interest, notably to provide a basis on which vaccination recommendations could be made for the numerous international travellers visiting the country.

We studied knowledge of nutritional needs during pregnancy and lactation in 150 pregnant Saudi women at three primary health care centers in Riyadh, Saudi Arabia. We used an interview schedule to collect data regarding the women's knowledge and to determine the effects of certain independent variables on the knowledge scores. Green et al.'s (1980) PRECEDE model provided the theoretical framework for the study. Descriptive statistics, t test, and chi-square methods were used to analyze the data. The majority of the women had poor nutrition knowledge scores, with no significant differences among the three centers. A positive relationship was found between knowledge score and educational level. Negative relationships were found between knowledge score and number of pregnancies, number of deliveries, and number of living children. The findings have several implications for efforts to improve the health status of women in Saudi Arabia. PMID:8002417
Two species of plectropomid grouper (Plectropomus areolatus and P. pessuliferus) are found in the Red Sea. In Saudi Arabia these are the most valuable fishes by weight, averaging wholesale prices around US $15 per kilogram (personal observation). Over the past two decades, the number of fishing vessels in the Saudi Arabian Red Sea has tripled. Despite this increase in fishing effort Saudi Arabia has not implemented any marine resource management for Red Sea fisheries. Little biological data are currently available to inform managers. The research presented here addresses knowledge gaps on the growth pattern, longevity and sexual ontogeny of Plectropomus spp. in the Red Sea. Collections of each species were established by purchasing landed individuals from fishermen and fish markets distributed evenly between three latitudinal regions around the country. The total length of each fish was measured to the nearest millimeter. Age was estimated by enumerating annual bands visualized in transverse sections of sagittal otoliths. Sexual stage was determined via histological examination of gonadal tissue. Plots of total length versus age were fitted with reparameterized von Bertalanffy growth functions constrained to a size-at-settlement estimate of 20 mm. P. pessuliferus achieved a larger size (maximum 960 mm) and an older age (maximum 19 years) than P. areolatus (maximum size 570 mm, maximum age 9 years). While no regional patterns were found for P. pesuliferus, likelihood ratio tests revealed regional differences in growth pattern for P. areolatus, finding an increasing mean age, increasing mean length, and decreasing growth rate with decreasing latitude. In addition, males of P. areolatus were more abundant in the Southern region. These findings contradict existing theories about the effects of latitudinal temperature gradients on life history. It is hypothesized that the broader continental shelf in the Southern region may be providing a haven for these species in the
Objective was to ascertain the role of cardiac diseases as a risk factor for stroke in a cohort of Saudi children who were evaluated in a retrospective and prospective study. Children with cardiac diseases were identified from within a cohort of 104 Saudi children who presented with stroke. They were seen as inpatients in the Pediatric Wards or evaluated at the Outpatient Clinics of the Division of Pediatric Neurology (DPN), and the Division of Pediatric Cardiology at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). A comprehensive form for clinical, neuroimaging, neurophysiological and laboratory data retrieval was designed and completed for each patient. Cardiac evaluation included 12-lead ECG and serial echocardiograms. Cardiac catheterization and 24-hour ambulatory ECG (Holter) were conducted on clinical discretion. Cardiac diseases were the underlying risk factor for stroke in 6 (5.8%) of the 104 children (aged one month to 12 years). The patients (4males and 2 females) were evaluated at the DPN at a mean age of 5.3 years (range=1-8 years; median 6.5 years). Onset of stroke was at a mean age of 34 months (range= 4 months - 8 years; median = 30 months). Five patients had stroke in association with congenital heart disease (CHD), whereas the sixth had restrictive cardiomyopathy. The identified CHD consisted of membranous ventricular septal defect in a 5-year-old boy who had moyamoya syndrome and sickle cell b-thalassemia, asymptomatic patent ductus arteriosus (PDA) in a 17-months-old girl, atrioventricular canal defect and PDA in an 8-year-old boy who also had Down syndrome, partial anomalous pulmonary venous drainage in a one-year-old boy. The latter patient developed hemiparesis secondary to a septic embolus, which evolved into brain abscess involving the right fronto-preital region. This was successfully managed surgically

Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites. Here we report the association of tomato leaf curl Sudan virus causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia. The complete genome sequence analysis showed highest (99.9 %) identity with tomato leaf curl Sudan virus causing leaf curl disease in Arabian Peninsula. In phylogenetic relationships analysis, the identified virus formed closest cluster with tomato leaf curl Sudan virus. In recombination analysis study, the major parent was identified as tomato leaf curl Sudan virus. Findings of this study strongly supports the associated virus is a variant of tomato leaf curl Sudan virus causing disease in Sudan, Yemen and Arabian Peninsula. The betasatellites sequence analysis showed highest identity (99.8 %) with tomato leaf curl betasatellites-Amaranthus-Jeddah. The phylogenetic analysis result based on betasatellites formed closed cluster with tomato yellow leaf curl Oman betasatellites. The importance of these findings and occurrence of begomovirus in new geographic regions causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia are discussed. PMID:27366765

Materials and Methods: A case-controlled study of fifty newly-admitted patients at King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia diagnosed with colorectal cancer were interviewed to collect data on various dietary factors and their nutritional status. Their data were compared with a sex-matched control group aged fifty. Results: The consumption of meat high in fat, fried eggs and whole fat dairy products, and diet low in fibers 2-3 times or above per week increased the risk of colorectal cancer, while the consumption of whole wheat products, vegetables and fruits, and diet low in animal fats at the same rate per week may play a protective role against colorectal cancer in both men and women when compared to controls. Conclusions: The higher consumption of meat and fat from animal sources could increase the risk of colorectal cancer. The high consumption of whole wheat bread, fruits and vegetables with high fiber content could play a protective role against the risk of colorectal cancer in the Saudi society. Additional studies are needed in different regions of the Kingdom of Saudi Arabia to verify or refute these results.

The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods: Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results: Approximately half of all subjects (53.3% reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001. After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01, a higher attitude score (t=3.26; P=0.001, and male sex (t=10.45; P<0.001 were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively, whereas a lack of time was the main reason for males (59.5%. Conclusion: Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor

Full Text Available The dairy industry is a large and important business in Saudi Arabia. Although farms are administered to high international standards, some reproduction problems, of uncertain aetiology, are encountered. The most frequently seen are conception failures, abortions, stillbirths and the birth of weak or malformed calves. These conditions are suggestive of bovine viral diarrhoea virus (BVDV infection. Unfortunately, very little published information is available regarding the impact of this disease on cattle populations in Saudi Arabia. As a consequence, the present study was carried out and is the first of its kind in Saudi Arabia and the Gulf region. The aim of the study was to elucidate the role of in utero BVDV infection leading to the birth of weak or malformed calves on a large dairy farm in Saudi Arabia. The study was divided into two parts. Firstly, apparently healthy neonatal calves were sampled for the detection of pre-colostral serum antibodies to BVDV. The presence of these antibodies indicates exposure of the foetus to BVDV during the last two trimesters of gestation. Secondly, tissue samples from malformed neonatal calves were examined for the presence of BVDV antigens. Detection of such antigens confirms exposure of the foetus to the virus during the first trimester of gestation. The results of the investigation indicated that 36.1% of the neonatal calves were exposed to BVDV infection in utero. This is higher than what has been reported in the literature and suggests that dairy farmers in the Arabian Peninsula need to be made aware of the dangers of BVDV infections in their herds. The epidemiological significance of the results is discussed.

The objective of the survey was to compare habitats and bird life in the Asir region, particularly Jebal Souda and the Raydah escarpment protected area of the Saudi Wildlife Commission, and adjacent regions of the tihama, with those observed in July 1987 (Jennings, et al., 1988). The two surveys were approximately the same length and equal amounts of time were spent in the highlands and on the tihama. A number of walked censuses were carried out during 2010 on Jebal Souda, using the same meth...
Ingested corrosive material is a major pediatric emergency all over the world. The corrosive material can cause damage to the digestive tract, ranging from minor injury to strictures, and sometimes even death. We aimed to review the pattern of corrosive ingestion in children who had been admitted to Aseer Central Hospital in the Southwestern region of Saudi Arabia. This is a retrospective study of all children who had been admitted with a history of corrosive ingestion to Aseer Central Hospital over a period of five years period from 1990 to 1995. The records of 72 patients (38 males and 34 females) were reviewed. The data included age, sex, time lapse till admission, action taken by parents, presenting symptoms, general management given to the child, barium study, endoscopy, and the postcorrosive ingestion outcome of the child. The mean age of the pediatric patients was 28 + - 20 months. Different types of corrosives were encountered. The most common type was 5.25% hypochlorite in 36 patients (50%), kerosene in 12 patients (16.7%), caustic soda in nine patients (12.5%), hydrogen chloride and N-alkyl dimethyl benzyl ammonium chloride (HC and ADB) in eight patients (11.1%), and other material in seven patients (9.7%). Endoscopy was done in 30 patients (31.7%), 14 of whom were abnormal. Barium swallow was performed in 11 patients; five of them showed strictures that required frequent dilatation whereas one needed interposition surgery. Corrosive injury is still a major pediatric emergency among young children. It carries a major risk of complications (mainly stricture) and requires standardized management based on evidence-based medicine. (author)

Full Text Available The aim of this study is to assess self-medication practice among university students in the Al-Qassim Province of Saudi Arabia. A cross-sectional community-based survey was conducted by distributing a self-administered 18-item questionnaire among university students in the Al-Qassim Province of Saudi Arabia in the period between October and December 2012. The participants were selected using a convenience sampling technique. Data were collected from the questionnaire and analyzed using SPSS version 19. A total of 354 male students with an average age of 21.95 (SD ± 3.43 participated in this study. Our study showed that self-medication among male students was high (86.6% compared to results shown in other studies in the same region. Headache (59.9%, cough/cold (41% and fever (24.6% were the most common symptoms associated with self-medication. Congruent with the medical conditions reported, the most widely used medications without prescriptions were paracetamol (34.7%, followed by antibiotics (31.4% and nonsteroidal anti-inflammatory drugs (28.7%. Our study shows that antibiotics were sometimes irrationally used for self-treatment of cough and fever. Self-medication was highly frequent among the students. Influence of TV advertisements, high accessibility of pharmacies and convenience stores, as well as good buying power were found to be leading factors for self-medication among male university students.

Objective:To determine the current seroprevalence of antibodies against hepatitis A virus in selected group of children aged 1-6 years in Northern borders region, Saudi Arabia, and to identify risk factors for infection.Methods: A cross-sectional sero-epidemiological study of 950 children who attended 10 randomly selected primary health care centers (5 urban and 5 rural) was done. Parents of all children were subjected to a questionnaire including sociodemographic and housing environmental data. The determination of anti-HAV antibodies was carried out by ELISA-test.Results:The prevalence of HAV-IgG was 33.8% overall, 35.5% among males and 32.0% among females with no statistically significant difference. Multivariate logistic regression analysis revealed that increasing age, rural residence, non Saudi nationality, and non availability of safe municipal water source were the most important independent predictors for HAV seropositivity in the studied children.Conclusions:There is a clear decrease in hepatitis A prevalence in the studied children particularly in urban areas and indicates that a transition may be underway to intermediate endemicity and possible shift of the risk to the adult age with increased morbidity. So, we recommend including Hepatitis A in the schedule of routine childhood vaccinations.

Full Text Available The Philippines is one of few countries in the developing world that heavily relied on exporting its laborers to sustain its economic growth. Despite attempts by previous administrations to minimize sending Filipino workers abroad by improving working condition at home so that working abroad would no longer be compulsory but optional, many Filipinos continue to leave the country hoping to alleviate their families from poverty. This idea of working abroad has several implications for migrant workers especially in regions where labor policies are not clearly laid down and that rights and welfare of migrant workers are not protected. This paper seeks to elucidate the conditions of Overseas Filipinos Workers (OFWs in Saudi Arabia which strictly implemented “Saudization”2 policy since 2011. In particular, the paper tries to address the following questions: What does “Saudization” (nitaqat mean from Filipinos’ perspectives?; Who are affected by this policy and Why have OFWs been affected by such policy?; How did undocumented or illegal OFWs survive in previous years?; What policies they have implemented to counter it? This paper is centered on its main thesis that Saudi Nationalization policy, which is centered on solving socio-economic problems facing the young and unemployed population in several Gulf countries, has been the driver for these governments to strictly implement such a law and that many migrant workers including Filipinos working on specific areas together with undocumented ones are gravely affected.

A preliminary survey of Saudi Arabian Alcyonacea is presented, which combines classical taxonomy, multilocus molecular barcodes, and in situ photographs. We explored 14 locations along the west coast of the Kingdom of Saudi Arabia to assess the regional taxonomic diversity of non-gorgonian alcyonaceans. We collected samples from a total of 74 colonies, distributed among four families: 18 colonies of Alcyoniidae, 14 of Nephtheidae, 9 of Tubiporidae, and 33 of Xeniidae. We sequenced the octocorals using multiple nuclear [ribosomal Internal Transcribed Spacers (ITS) and ATP Synthetase Subunit α (ATPSα)] and mitochondrial [MutS homolog (mtMutS) and Cytochrome C Oxidase subunit one (COI)] loci, providing molecular barcodes which will: (1) allow direct comparison of biodiversity from this location to others for which molecular data are available, and (2) facilitate future identifications of these taxa. Finally, this preliminary phylogeny of sampled taxa provides insights on the resolution of mitochondrial versus nuclear loci, and highlights octocoral taxa that require further taxonomic attention. © 2013 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg.
The purpose of this study is to use geophysical imaging methods to identify the conjectured location of the ‘Qadimah fault’ near the ‘King Abdullah Economic City’, Saudi Arabia. Towards this goal, 2-D resistivity and seismic surveys were conducted at two different locations, site 1 and site 2, along the proposed trace of the ‘Qadimah fault’. Three processing techniques were used to validate the fault (i) 2-D travel time tomography, (ii) resistivity imaging, and (iii) reflection trim stacking. The refraction traveltime tomograms at site 1 and site 2 both show low-velocity zones (LVZ’s) next to the conjectured fault trace. These LVZ’s are interpreted as colluvial wedges that are often observed on the downthrown side of normal faults. The resistivity tomograms are consistent with this interpretation in that there is a significant change in resistivity values along the conjectured fault trace. Processing the reflection data did not clearly reveal the existence of a fault, and is partly due to the sub-optimal design of the reflection experiment. Overall, the results of this study strongly, but not definitively, suggest the existence of the Qadimah fault in the ‘King Abdullah Economic City’ region of Saudi Arabia.

This paper discusses natal and postnatal care services in Saudi Arabia, as revealed by the National Maternal & Child Health Survey of 1991. The latter was based on a national random sample of 150 clusters, with 6306 households, from urban and rural areas, of five geographic regions. The target of 6294 ever-married Saudi women, 15-49 years old included 6020 currently married women, of whom 1050 reported a pregnancy. Data on maternal care were analysed, including where and why natal care was attended, and for both natal and postnatal care, how much and by whom, by respondents' age, urban-rural residence, geographical location, and education of wife and husband. About three-quarters of the respondents had one or more births within the 5 years preceding the survey, with a total of 4777 children under six. Institutional deliveries reached 86 per cent and about 90 per cent of deliveries were attended by physicians or nurses with a ratio of 2:1. Postnatal care attendance amounted to 88 per cent mainly by physicians than nurses with a ratio of 5:1. In general, the above results describe relatively high coverage with natal and postnatal care services, which can still be improved through health education and community support, particularly of the women. Judging by the high level of institutional care and physician involvement, good quality of care is implied, but needs to be further confirmed, by defining morbidity and mortality patterns.

One of the most valuable groundwater reserves in Saudi Arabia is the Saq aquifer system (SAS), a thick (400-1200 meters) sandstone unit that extends across 300,000 km2 in Saudi Arabia and neighboring Jordan. Due to its high productivity and high water quality, current pumping and overexploitation of the aquifer has significantly lowered the groundwater level over the years. Understanding the recharge regimes of the SAS is critical for the development of sustainable exploitation of water resources in the region and for the establishment of appropriate management practices. In this study, we investigate the hydrologic setting of the SAS and seek to differentiate the degree of paleo versus modern contributions using a range of geochemical approaches. Multiple groundwater samples were collected from deep production wells tapping the SAS at depths between 375-1800 m and across a range of locations. Samples were analyzed for their chemical concentrations, stable isotopic compositions (δ18O and δ2H), and dissolved noble gas concentrations and isotopic ratios. Examining these data identifies unmixed pools of fossil groundwater at deeper depths as well as mixed shallower systems that indicate contributions from modern precipitation. Through isotopic and noble gas analyses, the relative age and timing of these recharge events was examined and show contributions from both glacial and inter-glacial periods, with some modest contributions from modern meteoric sources.

Objective: To establish molecular characterization of Plasmodium falciparum field isolates in Jazan Area of Saudi Arabia measured with highly polymorphic genetic marker, i.e. the merozoite surface protein 2(MSP 2).Methods: Blood samples were collected from 128 clinically suspected patients attending both Jazan and Sabia hospitals, Kingdom of Saudi Arabia. Both hospitals reflected urban and rural settings respectively. Analysis of central polymorphic region of MSP 2(3D7 and FC27 allelic families) was performed using nested PCR for malaria patients.Results: For MSP 2 allelic families of Plasmodium falciparum, 16 cases(53.3%) carried FC27 type and 14 cases(46.7%) carried 3D7 type, whereas no malaria cases harbored both allelic types. The present study showed that in urban area, 80% of FC27 fragments were 500 bp while in rural area it was 45.5%(P = 0.08). The FC27 400 bp allele was more prevalent in patients from rural than those from the urban area(P = 0.08). The most prevalent infecting 3D7 allele was the 3D7 300 bp in both areas. In the present study, there were no multiple infections.Conclusions: The limited genetic diversity which was observed in Jazan(considered as an endemic area) may be attributed to the small sample size or sustained malaria control program.

Background: Continuing medical education (CME) is an important and useful activity for updating knowledge in order to improve for outcome of health care. A CME update symposium on Infectious Diseases was therefore organized at the King Fahd Hospital of the University (KFHU), Al-Khobar, Saudi Arabia. Participants included clinicians, laboratory personnel and nursing staff from different hospitals and universities in Saudi Arabia. Objectives: To report the proceedings of the first CME on Infectious Diseases in the region and to evaluate it using a questionnaire-based feedback. Methodology: This CME was evaluated on specific feedback obtained on standardized evaluation forms provided during the symposium. The responses of 194 participants were statistically analyzed for the various components of the symposium. Results and Conclusion: Salient important issues covered during the program are presented. The CME included five sessions on: hospital acquired infections, immunology, mycotic diseases, malaria, lesihmaniasis and virology. Some lacunae were also identified. The evaluation of the scientific sessions showed a satisfaction level of 3.98 ± 0.59, on a scale of five. As this CME activity proved successful on many counts, it was concluded that it was worthwhile to conduct updates on infectious diseases on a regular basis. PMID:23008630
Full Text Available Five bee-fly species (Bombyliidae, Diptera have been listed in this paper as new to the Kingdom of Saudi Arabia. Four of the recorded species have been identified to the level of species, namely: Bombomyia discoidea (Fabricius, 1794, Spogostylum candidum (Sack, 1909, Exoprosopa linearis Bezzi, 1924, and Exoprosopa minos (Meigen, 1804, while the fifth one only to genus, Desmatoneura sp. The species have been collected from Al-Baha and Asir Provinces in the south-western part of the Kingdom. One of the four identified species, Exoprosopa linearis, has an Afrotropical affinity, and another two, Spogostylum candidum and Bombomyia discoidea, have considerable Afrotropical distributions, and this result agrees to some extent with studies considering these parts of the Arabian Peninsula, including Al-Baha and Asir Provinces, having Afrotropical influences and may be included in the Afrotropical Region rather than in the Palaearctic Region or the Eremic zone.

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

Full Text Available Abstract Background Bullying and sexual harassment of medical students by their teachers appears to be widespread phenomenon. However, nothing is published about its prevalence in conservative countries such as Saudi Arabia. This survey aims to ascertain the extent of these mistreatments among students in a Saudi medical school. Findings A cross-sectional questionnaire survey was conducted on a group of 542 clinical years’ medical students in a Saudi medical school to explore students' perceptions of their educational environment including exposure to different kinds of bullying. Bullying was defined as “a “persistent behaviour against a medical student that is intimidating, degrading, offensive or malicious and undermines the confidence and self- esteem of the recipient”. Results revealed that more than one quarter (28.0% of the surveyed students reported exposure to some sort of bullying during their clinical. Ninety percent of the reported insults were verbal, 6% sexual and 4% physical. Males were more exposed but difference was not statistically significant. Conclusions Bullying among Saudi medical students is an existing problem. A policy against bullying and harassment should be adopted in all of medical colleges to monitor this phenomenon and support students who have been bullied.

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

Background: The rate of preexisting diabetes mellitus (DM) in Saudi Arabia is one of the highest in the world. The role of preconception care (PCC) is well-established as a means of improving pregnancy outcomes in DM. Objectives: To assess the rate of preconception counseling, the level of PCC knowledge, and the rate of unplanned pregnancies in Saudi women with DM. Materials and Methods: A cross-sectional study was conducted among 355 Saudi women aged 18–49 years with self-reported DM. The study questionnaire contained variables about the provision of preconception counseling, knowledge of PCC facts, and the number of unplanned pregnancies after developing DM. The level of PCC knowledge was evaluated using a modified Likert scale. Statistical Package for Social Sciences 20 was used for statistical analysis. Descriptive statistics, mean and standard deviation, and percentages were calculated; t-test was used for statistical significance. Results: About one-third of the participants had received preconception counseling after being diagnosed with DM. Counseling on PCC for older and married participants was significantly less. Of the 355 participants, 42.8% had little or no PCC knowledge. All pregnancies that occurred after developing DM were unplanned. Conclusions: The rate of preconception counseling, the level of PCC knowledge in the studied Saudi women with DM is suboptimal, and none of the pregnancies that occurred after developing DM was planned. The study highlights the need for PCC programs that target all Saudi women of child-bearing age with DM, and their families starting at the age of puberty and at diagnosis of type 2DM, to optimize women's health and improve pregnancy outcomes.
Changing pattern of Saudi Arabia＇s oil exports Saudi Arabia （hereinafter referred to as Saudi） long time ranks No. one of world oil production and lost the title only in 2009 and 2010 due to cutting output which is slightly lower than the Russian output. It is predicted that global annual oil output in the next 10 years will be more than 4 billion tons, during which Saudi annual oil output will be up to 540-550 million tons, accounting for about 14 percent of global annual oil output. Saudi＇s 2005 oil exports of about 360 million tons accounted for 17.78 percent of the global oil exports, and 42.66% of the Middle East. Over the next 10 years, it is expected Saudi oil exports will reach 380-400 tons. Saudi plenty of spare oil production capacity and enhanced oil recovery will increase its remaining recoverable oil reserve,

Full Text Available Abstract Background data on HIV epidemiology and preventive measures in Islamic countries is limited. This study describes the results of 18-year of HIV surveillance in Saudi Arabia (SA and the preventive measures implemented from an Islamic perspective. Methods surveillance for HIV has been underway in SA since 1984. Indications for HIV testing include clinical suspicion, screening of contacts of HIV-infected patients, and routine screening of blood and organ donors, prisoners, intravenous drug users, patients with other sexually transmitted infections, and expatriates pre-employment. This is a case series descriptive study of all confirmed HIV infections diagnosed in SA from 1984 through 2001. Results a total of 6046 HIV infections were diagnosed, of which 1285 (21.3% cases were Saudi citizens. Over the 18-year surveillance period the number of HIV infections diagnosed annually among Saudi citizens gradually increased and, over the period 1997–2001, it reached to 84 to 142 cases per year. The number of cases per 100,000 population varied widely between regions with a maximum of 74 cases and a minimum of 2 cases. The infection was most common in the age group 20–40 years (74.6% and predominantly affected men (71.6%. The modes of transmission among Saudi citizens and expatriates, respectively, were as follows: heterosexual contact, 487 (37.9% and 1352 (28.4% cases; blood transfusion, 322 (25.0% and 186 (3.9% cases; perinatal transmission, 83 (6.5% and 19 (0.4% cases; homosexual contact, 32 (2.5% and 38 (0.8% cases; intravenous drug use, 17 (1.3% and 33 (0.7% cases; bisexual contact, 10 (0.8% and 14 (0.3% cases; unknown, 334 (26.0% and 3119 (65.5% cases. The number of HIV infections transmitted by blood or blood products transfusion declined to zero by year 2001 and all such infections occurred due to transfusions administered before 1986. At HIV diagnosis, 4502/6046 (74.5% patients had no symptoms, 787 (13.0% patients had non-AIDS defining
There are no available data about the prevalence of chronic kidney disease (CKD) and its risk factors in the general population of the kingdom of Saudi Arabia. To estimate the prevalence of CKD and its associated risk factors in the Saudi population, we conducted a pilot community-based screening program in commercial centers in Riyadh, Saudi Arabia. Candidates were interviewed and blood and urine samples were collected. Participants were categorized to their CKD stage according to their estimated Modification of Diet in Renal Disease (MDRD3)-based, the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and the presence of albuminuria. The sample comprised 491 (49.9% were males) adult Saudi nationals. The mean age was 37.4 ± 11.3 years. The overall prevalence of CKD was 5.7% and 5.3% using the MDRD-3 and CKD-EPI glomerular filtration equations, respectively. Gender, age, smoking status, body mass index, hypertension and diabetes mellitus were not significant predictors of CKD in our cohort. However, CKD was significantly higher in the older age groups, higher serum glucose, waist/hip ratio and blood pressure. Only 7.1% of the CKD patients were aware of their CKD status, while 32.1% were told that they had protein or blood in their urine and 10.7% had known kidney stones in the past. We conclude that prevalence of CKD in the young Saudi population is around 5.7%. Our pilot study demonstrated the feasibility of screening for CKD. Screening of high-risk individuals is likely to be the most cost-effective strategy to detect CKD patients (Author).

The sample comprised 491 (49.9% were males adult Saudi nationals. The mean age was 37.4 ± 11.3 years. The over-all prevalence of CKD was 5.7% and 5.3% using the MDRD-3 and CKD-EPI glomerular filtration equations, respectively. Gender, age, smoking status, body mass index, hypertension and diabetes mel-litus were not significant predictors of CKD in our cohort. However, CKD was significantly higher in the older age groups, higher serum glucose, waist/hip ratio and blood pressure. Only 7.1% of the CKD patients were aware of their CKD status, while 32.1% were told that they had protein or blood in their urine and 10.7% had known kidney stones in the past. We conclude that prevalence of CKD in the young Saudi population is around 5.7%. Our pilot study demonstrated the feasibility of screening for CKD. Screening of high-risk individuals is likely to be the most cost-effective strategy to detect CKD patients.
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 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

Coral reef communities between 26.8 °N and 18.6 °N latitude in the Saudi Arabian Red Sea were surveyed to provide baseline data and an assessment of fine-scale biogeography of communities in this region. Forty reefs along 1100 km of coastline were surveyed using depth-stratified visual transects of fish and benthic communities. Fish abundance and benthic cover data were analyzed using multivariate approaches to investigate whether coral reef communities differed with latitude. A total of 215 fish species and 90 benthic categories were recorded on the surveys. There were no significant differences among locations in fish abundance, species richness, or among several diversity indices. Despite known environmental gradients within the Red Sea, the communities remained surprisingly similar. The communities do, however, exhibit subtle changes across this span of reefs that likely reflect the constrained distributions of several species of reef fish and benthic fauna. PMID:26608504

A newly recognized Tertiary dike complex and comagmatic volcanic rocks exposed on the central Saudi Arabian coastal plain record early stages of magmatism related to Red Sea rifting. Intrusive and stratigraphic relationships, and new potassium-argon dating indicate episodic magmatism from about 30 Ma to the present. Additional stratigraphic and radiometric evidence suggests that limited rift-related magmatism may have began as early as about 50 Ma ago. An early phase of crustal extension in the region was accompanied by faulting and graben formation and by dike-swarm intrusion. The style of extension and intrusion changed approximately 20 Ma ago. Localized volcanism and sheeted dike injection ceased and were replaced by the intrusion of thick gabbro dikes. This change may mark the onset of sea-floor spreading in the central Red Sea.
Measurements of 14 polycyclic aromatic hydrocarbons (PAH) have been made in Jeddah, Saudi Arabia, with a view to establishing the concentrations in this major city, and quantifying the contributions of major sources. Particulate and vapour forms have been sampled and analysed separately. The concentrations are compared to measurements from other sites in the Middle Eastern region and are towards the lower end of the range, being far lower than concentrations reported from Riyadh (Saudi Arabia), Assiut (Egypt) and Tehran (Iran) but broadly similar to those measured in Damascus (Syria) and higher than those measured in Kuwait. The partitioning between vapour and particle phases is similar to that in data from Egypt and China, but with many compounds showing a higher particle-associated percentage than in Birmingham (UK) possibly reflecting a higher concentration of airborne particulate matter in the former countries. Concentrations in Jeddah were significantly higher at a site close to the oil refinery and a site close to a major ring road than at a suburban site to the north of the city. Application of positive matrix factorisation to the pooled data elicited three factors accounting respectively for 17%, 33% and 50% of the measured sum of PAH and these are interpreted as arising from gasoline vehicles, industrial sources, particularly the oil refinery, and to diesel/fuel oil combustion. - Highlights: • Measurements of 14 PAH compounds in vapour and particulate phases at three sites. • Comparison of concentrations across Jeddah and Middle Eastern regions. • Application of positive matrix factorisation to identify possible sources

Changes in socio-cultural patterns, economic activities, and the technologies for agricultural productions and climate controls are bringing new patterns of visual qualities to the age-old vernacular landscape of Saudi Arabia's Asir region. Unfortunately, the lack of reference between old and new is threatening to destroy the overall environmental quality that is one of the region's greatest economic and cultural assets. Through detailed examination of Al-Alkhalaf vernacular landscape in Asir, one of the largest villages, this paper defines the major components of the landscape and assesses the basis for their aesthetic qualities and values. Throughout the traditional era, a sense of beauty was imparted to this vernacular landscape through an unconscious balancing of natural systems and human needs. Such results owed much to the management efforts of a homogenous group of villagers expressing consensus about their place in the world. Today, in the more complicated context of modern Saudi Arabia, a new appreciation for landscape traditions arises and vernacular invites pertinent commentaries. A more conscious effort is needed to achieve the same old sense of regional and aesthetic values. The paper suggests that such an effort should begin by employing concepts like aesthetic values, aesthetic qualities and visual qualities when searching for new expressions of the relationship between people and nature.

This paper reports on the prevalence of oral lichen planus among 4277 dental patients aged 18-73 years, seen in the Dental Department, King Fahad Central Hospital, Gizan, Saudi Arabia, between 1982 and 1987. Oral mucosal lesions, diagnosed as lichen planus, were clinically and histologically identified in 72 subjects (40 males and 32 females). The average age of the affected group was 49 years. No correlation was evident between lichen planus and tobacco habits in this study, nor was there any association with diabetes or hypertension. The average period of follow-up was 3.2 years, during which time 4 patients developed malignant transformation of their oral lesions. The prevalence of lichen planus in this study was 1.7%, which is higher than the prevalence figures reported earlier for this disease in Saudi Arabia. (author)

Saudi Arabia is the third-largest Arab country with a moderate annual burden of tuberculosis. However, tuberculosis (TB) is among several infectious diseases that have not been brought under control, despite the government's considerable efforts. This is clearly evidenced by the ongoing transmission of several imported and indigenous clades of Mycobacterium tuberculosis. In addition, the country faces the threat from rising proportions of extrapulmonary TB, non-tuberculous mycobacterial infections, and drug resistance. Furthermore, the country falls behind the global targets set by World Health Organization for the success rate of TB treatment. The country needs more population-based research studies, centralized and easily accessible clinical data registries, and centralized research and diagnostic facilities. This review focused on the trends of mycobacterial infections and on future proposals to improve TB control measures in Saudi Arabia. PMID:25771458
Full Text Available Background: Pigmentary demarcation lines (PDL are physiological abrupt transition lines between hyperpigmented skin and lighter areas. Recent evidence suggests that they involve the face. Aims: To survey facial PDL in Saudi females referred to general dermatology clinics for various complaints and determine any associated risks. Methods: Screening for facial lines was done in general dermatology clinics over a year. Whenever a patient was found to have facial PDL, a detailed questionnaire and examination were undertaken. Results: Out of 1033 patients screened, 144 patients (14% were found to have at least one of the facial PDLs. The median age of onset was 16 years. The most common line was F with 76 patients (53%. Family history was positive in 51 patients (35%. Conclusion: Facial PDL is a common and chronic pigmentary problem in Saudi women. It should be recognized and differentiated from other similar diseases like melasma. A significant proportion of patients have a milder presentation.

Full Text Available The purpose of this paper is to test the impact of oil price shocks on the stock markets of the two biggest and most liquid GCC equity markets, those of Kuwait and Saudi Arabia. It is expected that the two stock markets react similarly to oil price shocks. Actually the results show heterogeneity in responses. While there is prima facie evidence that both stock markets are influenced positively and linearly by oil price shocks, this evidence disappears when additional variables are added to the regressions. With the larger specification oil price shocks do not impact, neither linearly or non-linearly, Kuwaiti stock markets. By contrast Saudi markets react non-linearly to both oil price shocks and shocks in the US S&P 500. The only common feature for both equity markets is the positive relation with the shocks in the US S&P 500.

Full Text Available The present work aims to molecularly characterize some popular Saudi fish species. Seven popular Saudi fish species namely, Morgan (Nemipteru sjaponicus, Mousa (Solea solea, Hamor (Greasy grouper, Shour (Lethrinus lentjan, Dennis (Caranxsex fasciatus, Harid (Scarus arabicus and Black surgeon (Acanthurus gahhm were characterized using six RAPD and three ISSR as well as Rep-PCR markers. These markers produced 187 distinct bands 89.4% were considered as polymorphic bands and 10.6% were considered as monomorphic bands. The RAPD OPA-06 primer revealed 100% polymorphism for 19 produced bands where band width ranged from 190 to 2100 bp. Likewise Rep- PCR ERIC1R primer exhibited 100% polymorphism for 18 bands produced bands where band width ranged from 50 to 1400bp. Data of the three types of genetic markers were combined for phylogenetic analysis. The resulted dendergram produced two large linages with around 59% genetic similarity. One linage only included Morgan (Nemipteru sjaponicus, and the other linage comprised the other six species. This result suggested that this six species were descended from Morgan fish. The second linage comprised two clades; the first clade contained four species (Mousa, Hamor, Shour, and Dennis, where the next clade included only Harid and Black surgeon. Generally genetic distance among native fishes was relatively low. The smallest genetic distance (0.512 was estimated between Shour fish and Black surgeon fish. To the best of our knowledge this work is breaking new ground in two directions, first, molecular characterization of Saudi fish, second employment Rep- PCR genetic marker for molecular characterization of fish species. This work could be considered as preliminary work towards an establishment of Saudi genetic conservation program.

Thus, an understanding of the factors that help or harm the attractiveness of a smile is an important step in creating attractive smiles. This study aimed to identify factors that affect smile perception and attractiveness among the Saudi population. A cross-sectional study was conducted among the Saudi population. Questionnaires were distributed to 130 dentists and final-year dental students, and to 130 laypersons. The questionnaire contained six smile photographs created by Photoshop® software. There was a statistically significant difference in scale ratings, based on participant background, for the “gummy: smile picture (P-value =0.003, diastema picture (P-value =0.000 and the “Reverse” smile picture (P-value =0.004. As for sex, males significantly underscored the gummy picture (P-value =0.009. Older people accepted the gummy smile less than did younger people, but diastema was considered as one of the variations that spoiled the attractiveness of the smile. “Dental background” participants significantly identified the ideal smile better than the “nondental” group. The perception of diastema as a sign of beauty among Saudi population in the past has definitely changed, according to the results of our study, where diastema and reverse smile received the lowest score in this survey.

Full Text Available Background : Idiopathic pulmonary fibrosis (IPF is rare and can be challenging to diagnose. Limited data is available from the Middle Eastern region, especially Saudi Arabia. Methods: This was a retrospective study that looked at all the patients diagnosed with IPF between 2007 and 2012 at two tertiary care hospitals in Saudi Arabia. We collected the demographical, clinical, laboratory and radiological data from the patients′ medical records. Medications administered and 1 year survival was also assessed. Results : Between 2007and 2012, 134 IPF patients were identified. Their baseline characteristics (Mean ± SD included: age 64 ± 13 years, body mass index 29 ± 8 kg/m 2 , FEV 1 56 ± 15 percent of predicted, FVC 53 ± 13 percent of predicted, FEV 1 /FVC 0.81 ± 0.09, total lung capacity 75 ± 13 percent of predicted, diffusing capacity of the lung for carbon monoxide 57 ± 15 percent of predicted, on home oxygen at presentation 71 (53%, mean ejection fraction 0.50 ± 0.07, mean pulmonary artery systolic pressure (via echocardiogram 40 + 22 mmHg, presentation mean S pO2 92 ± 7%, presentation 6-min walk distance 338 ± 64 m and lowest S pO2 during 6-min walk test 88 ± 5%. Patients were predominantly female (56%, and 42% of patients had diabetes and were active smokers. The IPF patients′ frequency of hospital admission (n = 99 was 2.4 ± 1.7 per year and duration of hospital stay (n = 99 was 17.4 ± 23.8 days. Overall 1 year survival in all IPF patients was good, 93% (124 patients remained alive after 1 year. Conclusions : In Saudi Arabia, IPF patients tended to be slightly older and the disease progression was somewhat slower than reported IPF cohorts in other populations. They had frequent hospital admissions and a long hospital length of stay. The influence of genetics and co-morbid diseases on the incidence and outcome of IPF should be explored further.

Full Text Available This paper investigates the long-term and causal relationship between energy intensity, real GDP per capita, urbanization and industrialization in Saudi Arabia over the period 1971–2012 using the breakpoint unit root tests developed by Perron (1989 and the autoregressive distributed lag (ARDL model bounds testing to cointegration proposed by Pesaran et al. (2001 and employing a modified version of the Granger causality test proposed by Toda and Yamamoto (1995. Additionally, to test the robustness of the results, the fully modified ordinary least squares (OLS regression, the dynamic OLS regression, and the Hansen test are used. Our results show that the variables are cointegrated when energy intensity is the dependent variable. It is also found that urbanization positively affects energy intensity in both the short term and the long term. Causality tests indicate that urbanization causes economic output that causes energy intensity in the long term. Our results do not support the urban compaction hypothesis where urban cities benefit from basic public services and economies of scale for public infrastructure. Therefore, measures that slow down the rapid urbanization process should be taken to reduce energy intensity in Saudi Arabia. In addition, reducing energy inefficiency in energy consumption should be a strategy to attain sustainable development in the near future in Saudi Arabia.
Full Text Available Background/Aim: α-1 antitrypsin (AAT deficiency results from mutations of the protease inhibitor (PI. The AAT gene is mapped on chromosome 14 and has been associated with chronic liver disease and chronic obstructive pulmonary disease (COPD. Objective: To determine the frequency of AAT mutations on S and Z carrier alleles in healthy Saudi individuals from Qassim Province in Saudi Arabia. Patients and Methods : A total of 158 healthy, unrelated participants from Qassim Province were recruited. They were genotyped for the two AAT-deficiency alleles, PIFNx01S and PIFNx01Z, using polymerase chain reaction, with primers designed throughout to mediate site-directed mutagenesis. Results: Of the 158 subjects, 11.39% were carriers for the S mutation (i.e., had the MS genotype, whereas 2.53% were carriers for the Z mutation (i.e., had the MZ genotype. The SZ genotype was present in 3.8% of subjects, while the homozygous genotype SS was present in 1.9% of subjects. No subjects showed the ZZ mutant genotype. Accordingly, frequency of the mutant S and Z alleles of AAT gene was 9.49% and 3.19%, respectively. Conclusion: The results obtained showed a high prevalence of the AAT deficiency allele in the Saudi population. This probably warrants adoption of a screening program for at-risk individuals, so that they might initiate adequate prophylactic measures.

Full Text Available Vitamin D deficiency has emerged as a public health problem worldwide due to its important role in health and disease. The present work is intended to examine prevalence of vitamin D deficiency among pregnant Saudi women and related risk factors. A cross-sectional study was carried out at King Fahad Medical City in Riyadh, Saudi Arabia. Serum 25-hydroxy vitamin D (25(OHD was measured by enzyme-linked immunosorbent assay in 160 pregnant women during the first trimester of pregnancy. Socio-demographic, lifestyle and maternal characteristics were collected and vitamin D intake was assessed using a 24-h dietary recall. Weight and height were measured using standardized methods. Vitamin D deficiency (25(OHD < 50 nmol/L and insufficiency (25(OHD = 50–74 nmol/L were reported in 50% and 43.8% of the study sample, respectively. Median serum 25(OHD concentration was 49.9 nmol/L. Adequate vitamin D intake (≥600 IU/day was reported among only 8.1% of pregnant women. Age group, educational level, sun exposure frequency and daytime and daily practice of exercise were significantly associated with vitamin D status. Overall, vitamin D deficiency was common among pregnant Saudi women in Riyadh. Steps should be taken to address the current situation, including increased sunlight exposure, consumption of fatty fish, and vitamin D supplements.

Full Text Available Parkinson's disease (PD is one of the major causes of parkinsonism syndrome. Its characteristic motor symptoms are attributable to dopaminergic neurons loss in the midbrain. Genetic advances have highlighted underlying molecular mechanisms and provided clues to potential therapies. However, most of the studies focusing on the genetic component of PD have been performed on American, European and Asian populations, whereas Arab populations (excluding North African Arabs, particularly Saudis remain to be explored. Here we investigated the genetic causes of PD in Saudis by recruiting 98 PD-cases (sporadic and familial and screening them for potential pathogenic mutations in PD-established genes; SNCA, PARKIN, PINK1, PARK7/DJ1, LRRK2 and other PD-associated genes using direct sequencing. To our surprise, the screening revealed only three pathogenic point mutations; two in PINK1 and one in PARKIN. In addition to mutational analysis, CNV and cDNA analysis was performed on a subset of patients. Exon/intron dosage alterations in PARKIN were detected and confirmed in 2 cases. Our study suggests that mutations in the ORF of the screened genes are not a common cause of PD in Saudi population; however, these findings by no means exclude the possibility that other genetic events such as gene expression/dosage alteration may be more common nor does it eliminate the possibility of the involvement of novel genes.
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)
Saudi Arabia's role in global energy markets is changing. The kingdom is reshaping itself as a supplier of refined petroleum products while moving beyond its long-held role as a simple exporter of crude oil. This change is commensurate with the typical development trajectory of a state progressing to a more advanced stage of global economic integration. Gains from increased refining include reducing fuel imports and capturing margins now bequeathed to competitors. Refining also allows the kingdom to export its heavy crude oil to a wider array of customers, beyond select importers configured to handle heavy crudes. However, the move also presents strategic complications. The world's 'swing supplier' of oil may grow less willing or able to adjust supply to suit market demands. In the process, Saudi Arabia may have to update the old “oil for security” relationship that links it with Washington, augmenting it with a more diverse set of economic and investment ties with individual companies and countries, including China. -- Highlights: •Saudi Arabia is diverting crude oil into an expanding refining sector. •In doing so, the kingdom is moving beyond its role as global “swing supplier” of crude oil. •The kingdom will benefit from increased refining, including enhanced demand for heavy crude. •Strategic complications may force it to seek security partners beyond Washington

This study was designed to investigate the dietary components which are likely to contribute to osteoporosis in postmenopausal Saudi women. In the present study, 36 osteoporotic postmenopausal and 25 healthy postmenopausal women as cases and controls respectively were selected from Armed Forces Hospital, Riyadh, Saudi Arabia. The study has designed to collect the data about the general characteristics (age, marital status, education, number of pregnancies, activity level, income and housing), anthropometric measurements, medical history and dietary intake by using both the methods (24 h recall, food frequency questionnaire). Serum samples were analyzed for calcium, phosphorus, vitamin D and Para Thyroid Hormone (PTH) and they were correlated with Bone Mineral Density (BMD). Food intake items were correlated with hip, neck and spin BMD. In results, cases found significantly older than controls and had history of bone fractures. Cases were consumed significantly less dietary calcium than controls. Serum parameters did not show any significant differences. However significant correlation was found between serum level of PTH and calcium with BMD of spine and right neck femur respectively. Banana and Mataziz (locally prepared dish with vegetables) showed positive correlation with hip BMD. A negative significant correlation was found between Arabian coffee and right neck femur BMD. In conclusion, Saudi women require encouragement to consume adequate amounts of calcium, fruits and vegetables in combination with maintaining a daily physical activity and space in child birth.

Saudi Arabia's dependence on oil and gas to generate electricity and to desalinate sea water is widely perceived to be economically and politically unsustainable. A recent business as usual simulation concluded that the Kingdom would become an oil importer by 2038. There is an opportunity for the country to over come this problem by using its geothermal energy resources. The heat flow and heat generation values of the granites spread over a cumulative area of 161,467 sq. km and the regional stress regime over the western Saudi Arabian shield strongly suggest that this entire area is potential source of energy to support 1) electricity generation, 2) fresh water generation through desalination and 3) extensive agricultural activity for the next two decades. The country can adopt a policy to harness this vast untapped enhanced geothermal systems (EGS) to mitigate climate and fresh water related issues and increase the quantity of oil for export. The country has inherent expertise to develop this resource.
Full Text Available A preliminary study was conducted to know the age, sex distribution and clinical pattern of cutaneous leishmaniasis (CL in a remote hilly area, Faifa, Gizan situated in the South West region of the Kingdom of Saudi Arabia. C L accounted for nearly 5% of the new outpatient attendance in the study period (1988-90 of 20 months. Out of the 140 new patients who formed the study group, 82 were males (58.57% and 58 females (41.43% in the age range of 9 months to 60 years. Ninety two patients were children (65.71% below 15 years. including 58 boys and 34 girls and CL is a major public health problem in children of this area. The fact that out of 140 affected individuals, 134 were local Saudis and 6 non-Saudis reveals the autochthonous nature of the disease in this region. The clinical spectrum included dry crusted ulcers, erythematous indurated plaques, nodules, papules, and oozing shallow ulcers. The lesions were distributed mostly on face and extremities. Response to pentostam (Sodium stibogluconate was highly satisfactory.

Conclusion: There is a worrisome lack of knowledge regarding content and benefits of PR programs among Saudi health care providers treating COPD patients. These findings imply that improving awareness and increasing education of the health care providers regarding PR will be required before PR can be more widely implemented as an integral treatment modality for patients with COPD in Saudi Arabia.
The Saudi health sector has witnessed a significant progress in recent decades with some Saudi hospitals receiving international recognition. However, this progress has not been accompanied by the same advancement in the health informatics field whose applications have become a necessity for hospitals in order to achieve important objectives such…

Full Text Available Limited data exit on the epidemiology of cardiovascular risk factors in Saudi Arabia particularly in relation to the differences between local citizens and expatriates. The aim of this analysis is to describe the current prevalence of cardiovascular risk factors among patients attending general practice clinics in Saudi Arabia. In a cross- sectional epidemiological study, the presence of cardiovascular risk factors (hypertension, diabetes, dyslipidaemia, obesity, smoking, and abdominal obesity was evaluated in stable adult outpatients attending primary care clinics in Saudi Arabia. Groups comparison were made between local Saudi patients and expatriates. A total of 550 participant were enrolled form different clinics in Saudi Arabia (71% were male, mean age was 43 ± 10 years. Nearly half of the study cohort had more than two cardiovascular risk factors (49.6%. Dyslipidemia had the highest prevalence (68.4%. Furthermore, prevalence of hypertension (47.5% vs. 31.4%, dyslipidaemia (75.2% vs. 55.1% and abdominal obesity (63.9% vs. 52.2% were higher among expatriates compare to Saudis (p-value < 0.001. This analysis clearly shows that there is a high prevalence of cardiovascular risk factors prevalence in Saudi population. In addition, a significant proportion of patients with risk factors have poor overall control. Programmed community based screening is needed for all cardiovascular risk factors in Saudi Arabia. Increased awareness and improved primary care services may decrease incidence of coronary artery disease and improve overall quality of life.

In this study, spatial and temporal distributions of tropospheric NO2 vertical column densities over Pakistan and Saudi Arabia during the time period of 2004-2015 are discussed. Data products from the satellite instrument OMI are used. The results show a large NO2 growth over major cities of both countries, particularly the areas with rapid urbanization. Different seasonal cycles were observed over both countries. Especially, seasonal variation in tropospheric NO2 over Pakistan is largely impacted by the photolysis rate, OH radical and monsoon rains in addition to soil emissions, agriculture fires and other anthropogenic activities. While in the case of Saudi Arabia, the seasonal variation in tropospheric NO2 is completely driven by thermal power generation. Furthermore, different regions of Pakistan exhibited different seasonal trends. In the provinces of Punjab (north-east), Khyber Paktunkhwa (north-west) and Sindh (south-east), NO2 columns are maximum in winter and minimum in summer months while a reversed seasonality was observed in the province of Baluchistan (south-west). We compared the observed Spatio-temporal patterns to existing emission inventories and found that for the most populated provinces the NOx emissions are clearly dominated by anthropogenic sources. In these areas also the strongest positive trends were observed. NOx released from soils and produced by lightning both together contribute about 20% for the provinces of Punjab, Sindh, and Khyber Pakhtunkhwa, while its contribution in Baluchistan is much stronger (~50%). NOx emissions from biomass burning are negligible. This finding can also explain the observed summer maximum in Baluchistan since the highest lightning activity occurs during the Monsoon season. Our comparison also indicates that the inventories of anthropogenic NOx emissions over Pakistan seem to underestimate the true emissions by about a factor of two.

The emergence of resistance to last-resort antibiotics is a public health concern of global scale. Besides direct person-to-person propagation, environmental pathways might contribute to the dissemination of antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Here, we describe the incidence of blaNDM-1, a gene conferring resistance to carbapenems, in the wastewater of the city of Jeddah, Saudi Arabia, over a 1-year period. blaNDM-1 was detected at concentrations ranging from 10(4) to 10(5) copies/m(3) of untreated wastewater during the entire monitoring period. These results indicate the ubiquity and high incidence of blaNDM-1 in the local wastewater. To track the bacteria carrying blaNDM-1, we isolated Escherichia coli PI7, a strain of sequence type 101 (ST101), from wastewater around the Hajj event in October 2013. Genome sequencing of this strain revealed an extensive repertoire of ARGs as well as virulence and invasive traits. These traits were further confirmed by antibiotic resistance profiling and in vitro cell internalization in HeLa cell cultures. Given that this strain remains viable even after a certain duration in the sewerage, and that Jeddah lacks a robust sanitary infrastructure to fully capture all generated sewage, the presence of this bacterium in the untreated wastewater represents a potential hazard to the local public health. To the best of our knowledge, this is the first report of a blaNDM-1-positive E. coli strain isolated from a nonnosocomial environment in Saudi Arabia and may set a priority concern for the need to establish improved surveillance for carbapenem-resistant E. coli in the country and nearby regions.

Several challenging obstacles remain to increasing the number of organ donations from deceased patients in a hospital setting. These include medical, administrative, and ethical issues. Possible medical obstacles include the failure of early recognition of possible donors and inadequate care of potential and actual donors. To maximize the use of donated organs, proper care of the donors and expedited donor consent cannot be overemphasized. The care rendered to patients should ensure appropriate perfusion and nutrition of the organs, with meticulous follow-up until organ recovery. For example, patients involved in accidents are presumed to be healthy, but many have no available medical history on file. At the time of organ recovery, unexpected infections or malignancies can be minimized by raising the index of suspicion of the presence of serious conditions in donors, especially in donors with unknown medical history. A careful physical examination and an appropriate and aggressive laboratory investigation may disclose the cause of suspected clinical conditions in these potential donors. Individuals who work in intensive care units are the main group of health care providers directly involved in the process of organ donation. Appointing a donor coordinator in each intensive care unit could improve all aspects of organ donation. Such coordination could harmonize efforts toward the goals mentioned above and surmount the obstacles encountered during deceased-donor organ donation. Here, we describe the preliminary results of the Proactive Detection Program, a collaboration between the Saudi Center for Organ Transplantation (the national organ donation and transplant supervising center) and intensive care units of donating hospitals. With its success in Saudi Arabia, it is hoped that it will be widely adopted in other regions. PMID:26640899
Full Text Available Moringa peregrina and M. oleifera are the only Moringa species found in Saudi Arabia. Both species are drought resistant and have very high nutritional and medicinal properties. Detection of genetic diversity is of great value for the improvement of nutritional and medicinal value of these plants. The aim of the present study was to characterize a new biotype Moringa observed in Al Bahah Region, Saudi Arabia. We used 11 RAPD and 15 ISSR primers to characterize and compare the new biotype with M. peregrina and M. oleifera. Level of polymorphism generated by each marker was calculated. We also calculate Nei and Li’s coefficient to measure the genetic distance between the studied species. Level of polymorphism generated by RAPD and ISSR was 46% and 57%, respectively. RAPD and ISSR primers revealed that the new biotype shared 55 amplicons (45.08% with both M. peregrina and M. oleifera, 28 amplicons with M. peregrina (22.95%, 21 amplicons (17.21% with M. oleifera, and displayed 18 unshared amplicons (14.75%. Based on RAPD data, genetic distance between M. oleifera and M. peregrina was 0.32, whereas genetic distance between the new biotype and M. oleifera and M. peregrina was 0.21 and 0.29, respectively. For ISSR data, genetic distance between M. oleifera and M. peregrina was 0.5, whereas genetic distance between the new biotype and M. oleifera and M. peregrina was 0.36 and 0.34, respectively. Based on these results we suggested that the new biotype is a hybrid crossbred between M. peregrina and M. oleifera.

Results: The survey enrolled 5,000 participants, 79%male (39.6% from Jeddah; 20% from Riyadh; and 20% from Jazan, aged between 15 and 45 years. Of the total, 1288 (25.8% had not heard about HIV/AIDS. Knowledge of HIV transmission was poor in 90% of the respondents. Of the total, 737 had read about HIV/AIDS materials and 649 participants had been previously tested for HIV. The majority of participants (85% held a negative attitude toward people living with HIV/AIDS. Those who were knowledgeable about HIV/AIDS expressed more a positive attitude. One-fifth (968, majority were men; single 55%, married 45% had engaged in non-marital sexual activity. The largest proportion of the individuals who had engaged in non-marital sex were single (54.9% followed by the married ones (40.4%. Men cited pleasure as the main reason for such activity (84.6%, whereas women (73.4% cited financial gain. Of the respondents, 53.9 and 32.1% believed that TV and schools were the best media through which information with regard to HIV/AIDS could be imparted. Conclusions: Knowledge of HIV/AIDS, its mode of transmission, and prevention measures was poor. Educational programs specifically targeted toward this group were required.
Background: One of the important complications of diabetes is diabetic-foot-ulcer, also reported in Saudi Arabia, like other countries. Similarly, the complications, like retinopathy and nephropathy are also occurring in diabetic patients of this region. Apart from the care and monitoring of these patients, it is important to find out association between these complications and their relation with common factors, like HbA1c levels. Such relation is not yet reported in literature. Objective: Therefore, this study was planned to find out association between neuropathy (leading to high risk foot) and retinopathy by the estimation of HbA1c levels in Saudi population. Methods: After exclusion of the cases of gestational diabetes and children with type-1 diabetes, 333 Patients having age 21 to 97 years were examined in the Diabetology Clinic of Diabetes Centre, Aseer Central Hospital, Abha. All patients were screened for neuropathy (High risk of the foot) and retinopathy (by Fundus Photography). HbA1c levels were determined, using standardised procedure. The obtained data was analysed statistically by SPSS-12 for Windows. Results: HbA1c levels of less than or equal to have been found to be associated with neuropathy, high risk foot, and as well as non- proliferative and proliferative retinopathy. Pearson chi square test has demonstrated association between progressive retinopathy and development of high risk foot. Conclusion: The observed data indicate poor glycemic or diabetes control on the basis of higher HbA1c levels and strong association between high risk foot and the development of progressive retinopathy.

Inspite of having so much sunshine, Saudi Arabian population is suffering from the deficiency of the 'sunshine vitamin', vitamin D, measured in the serum as 25-OHD level. According to a recent report, about 83.6% of Saudi population is vitamin D deficient. 31.9% have severe, 32% have moderate and 19.7% have mild vitamin D deficiency (VDD). The severity of VDD differs with age, gender and region. Females are more severely vitamin D deficient than males. Various factors contributing towards it deficiency are linked to their housing designs, religious practices, lifestyle choices and dark skin color. The increasing incidences of breast, prostate and colon cancer among this society are also raising an alarm. The presence of vitamin D receptor (VDR) and the enzyme responsible for conversion of the 25(OH)D in its active metabolite 25(OH)2D3 in extra renal tissue shows the involvement of vitamin D in other diseases like cancer, diabetes, multiple sclerosis etc. About 2000 genes related to various types of diseases are found to be regulated by VDRs. These genes possess vitamin D responsive elements (VDREs) in their promoters. Studies on population of other regions also have shown correlation with low serum levels of 25(OH)D and certain diseases So, we hypothesized that vitamin D deficiencies might cause a higher prevalence of these diseases in the Kingdom.

An average of less than 50 mm yr-1 of rainfall occurs in the hyperarid region of central Western Saudi Arabia. Climate change is projected to create greater variation in rainfall accumulation with more intense rainfall and flood events and longer duration droughts. To manage climate change and variability in ephemeral stream basins, dams are being constructed across wadi channels to capture stormwater, but a large percentage of this stored water is lost to evaporation. A dam/reservoir system located in Wadi Al Murwani in Western Saudi Arabia was recently constructed and is expected to contain a maximum stored water volume of 150 million m3. A hydrologic assessment of a dunefield lying 45 km downstream was conducted to evaluate its potential use for aquifer storage and recovery of the reservoir water. A 110 m elevation difference between the base of the dam and the upper level of the dunefield occurs, allowing conveyance of the water from the reservoir to the dunefield storage site by gravity feed without pumping, making the recharge system extremely energy efficient. Aquifer storage and recovery coupled with dams would allow water management during extreme droughts and climate change and has widespread potential application in arid regions. 2014 IOP Publishing Ltd.

Greater knowledge of the factors affecting fertility may help to decrease the incidence of infertility by allowing couples to avoid certain risk factors. The aim of our study was (1 to assess the knowledge and attitudes of infertile and fertile Saudi participants on infertility, possible risk factors, and social consequences; and (2 to determine the practices of infertile Saudi couples to promote their fertility before having them attend an in vitro fertilization (IVF clinic. Methods and materials: We conducted a cross-sectional study on 277 fertile participants from outpatient clinics and 104 infertile patients from the IVF clinic at King Abdulaziz Medical City between June 24, 2012 and July 4, 2012, using a previously validated interview questionnaire. Descriptive and analytical statistics were applied with a significance threshold of P ≤ 0.05. Results: A generally poor level of knowledge (59% and a neutral attitude (76% toward infertility were reported by participants. Mistaken beliefs commonly held by the study participants regarding the causes of infertility were Djinns and supernatural causes (58.8%, black magic (67.5%, intrauterine devices (71.3%, and contraceptive pills (42.9%.

Objective was to determine the prevalence of cagA+ and iceA genotypes among Helicobacter pylori (H. pylori) isolates from a group of Saudi patients with gastric complaints, and to find out any significant correlation between these strains and severe gastric clinical outcomes such as peptic ulcer and gastric cancer in Saudi population. A total of 1104 gastric biopsies from 368 patients who presented with symptoms suggestive of chronic gastritis, peptic ulcer disease, or gastric carcinoma were taken from the main hospitals in the Western region of Saudi Arabia from July 2004 to July 2005. We cultured the samples for H. pylori and a polymerase chain reaction was carried out to check for the presence or absence of cagA gene and the status of iceA genotypes. Among the 368 suspected patients to be infected with H. pylori by means of clinical features and endoscopic findings; 103 (28%) were positive using culture technique. The relation of the presence of cagA and the development of cases to gastritis and ulcer was statistically significant (p=0.0001). Furthermore, this study revealed that 100% of ulcer cases were infected with iceA1 with a statistically significant correlation (p=0.0001), while 94.6% of gastritis and 90.9% of normal were infected with iceA2 (p=0.0001). Moreover cagA+/iceA1 combined genotypes was statistically correlated with peptic ulcer (100%) but not cagA-/iceA1 (0%; p=0.0001).Certain H. pylori genotypes were more virulent than others. Multiple clinical implications based on these finding might be studied further.(author)

Full Text Available Aim: To estimate the prevalence and distribution of serum antibodies to BTV in different domesticated animals in different localities of Saudi Arabia. Materials and Methods: A total of 4845 field sera collected from different animal species within 10 districts in the Kingdom of Saudi Arabia were screened for the presence of group-specific BTV antibodies by competitive ELISA (c ELISA. Results: The overall BTV antibody prevalence was 54.1%, 53.3%, 44.8% and 25.7% in sheep, goat, cattle and camel respectively (at 95% confidence level. The Jizan and Eastern Province districts were the regions with the highest prevalence resulting 65.8% of sheep, 68.2% of goats, 49.3% of cattle, 44% of camel in Jizan and 65.8% of sheep, 62.5% of goats, 53.4% of cattle, 28.5% of camel in Eastern Province positive to c-ELISA. The second highest rate was in Najran district where the seropositivity for Bluetongue was found to be 60% of sheep, 57.9% of goats, 47.2% of cattle and 29.3% of camel. Our results recorded positive animals in all examined districts which indicate serological evidence of exposure to infection was widely distributed all over the country. Conclusions: These results demonstrate the high occurrence of the BTV that emphasize the necessity to a well-defined control strategy for preventing and controlling the BTV in Saudi Arabia. [Vet.

There are neither nuclear power reactors nor are there research reactors in Saudi Arabia. However, the country imports a lot of radioactive sources that are used in different fields such as medicine, hydrology, industry and research. Usage of radioactive material is governed by national and the IAEA regulations for the safe usage and transport of radioactive materials. KACST (King Abdulaziz City for Science and Technology) is an independent scientific organization established in 1977. It is the national competent authority that sets the rules of transporting, using and disposing of radioactive sources in Saudi Arabia.. This paper discusses the role of KACST and other authorities in the country regarding the 1) licensing and evaluation of the importing and exporting applications of radioactive sources and/or devices in Saudi Arabia, 2) The regulatory framework of radiation protection in Saudi Arabia, 3) the management of radioactive wastes in Saudi Arabia.

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

Full Text Available Aim: The aim was to measure the prevalence of smoking and identify its potential predictors among military personnel in Kingdom of Saudi Arabia (KSA. Materials and Methods: This cross-sectional study was carried out among military personnel in the five military regions of KSA between January 2009 and January 2011. The sample of 10,500 military personnel in the Saudi Armed Forces was equally divided among the five regions with a ratio 3:7 for officers and soldiers. A multistage stratified random sampling was used to recruit participants in the four services of the armed forces in the five regions. Information on sociodemographic characteristics with a detailed history of smoking was collected by means of a self-administered questionnaire. Bivariate analysis was used to identify the factors associated with smoking, and multiple logistic regression analysis to discover its potential predictors. Results: About 35% of the sample was current smokers, with higher rates among soldiers. The eastern region had the highest rate (43.0%, and the southern region the lowest (27.5%. Navy personnel had a higher risk of being current smokers (40.6%, and the air defense the lowest risk (31.0%. Multivariate analysis identified working in the navy, and low income as positive predictors of current smoking, while residing in the southern region, older age, years of education, being married, and having an officer rank were negative (protective factors. Conclusion: Smoking is prevalent among military personnel in KSA, with higher rates in the Navy and Air Force, among privates, younger age group, lower education and income, and divorced/widowed status. Measures should be taken to initiate programs on smoking cessation that involve changes in the environment that is likely to promote this habit.

Favorable conditions to tropospheric ozone (O3) formation are present over the Persian Gulf Region. Ozone is a well known pollutant affecting human health and natural ecosystems. Among the several factors contributing to the formation of the O3 hot spot over the Middle East, the presence of local emissions of its precursors needs to be considered. We report initial measurements of a suite of nonmethane hydrocarbons (NMHCs), an important component of volatile organic compounds (VOCs), which, coupled with nitrogen oxides in the presence of sunlight, are key chemical precursors of tropospheric O3. We measured 63 speciated C2-C10 NMHCs, in addition to methane (CH4) and carbon monoxide (CO) in three cities of Saudi Arabia (Jeddah, Mecca, and Madina; October-November 2012 and April 2013) and in the city of Lahore (Pakistan; December 2012). To put these data into perspective, we compare our results to data collected in Singapore (August-November 2012). We observed enhanced levels in all three Saudi Arabian cities compared to the local background and to those measured in Singapore. However, the Saudi levels are much lower than those measured in Lahore, where the sum of quantified NMHCs is about six times higher. For Madina, enhanced levels of the alkenes, ethyne and CO indicated that vehicle exhaust was the dominant source. In Jeddah and Mecca, the most abundant NMHC were the alkanes (47-61% of total measured NMHCs), which are more closely associated with emissions from natural gas, liquid petroleum gas (LPG), and gasoline evaporation. In Lahore, the hydroxyl radical (OH) reactivity, used to evaluate the importance of the different measured species toward ozone production, is three to six times higher than for the Saudi cities, and more than 20 times higher than for Singapore. For all urban areas reported here, among the measured compounds, the alkenes (especially ethene and propene) dominate in terms of OH reactivity because of a combination of their great abundance and
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
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 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.
Few studies have been conducted in the Saudi population on oral mucosal lesions. The purpose of this study was to evaluate the type and extent of oral lesions in a study among dental patients at a college of dentistry in Saudi Arabia. Over a 3-year period, 2552 dental outpatients were interviewed and investigated clinically for the presence of oral mucosal conditions. A thorough oral clinical examination was performed, including a radiographic examination. The diagnosis was confirmed histopathologically when necessary. Of 383 (15.0%) patients found to have oral mucosal lesions, females constituted 57.7% (n=221) and males 42.3% (n=162). The age range of the patients was between 15 to 73 years with a mean age of 38.2 years. The most commonly affected age group was 31 to 40 years, which comprised 21.4% (n=82) of all affected individuals. The least affected age group were individuals older than 61 years. The most common lesion was Fordyce granules (3.8%; n=98), followed by leukoedema (3.4%; n=86) and traumatic lesions (ulcer, erosion) in 1.9% (n=48). Tongue abnormalities were present in 4.0% (n=101) of all oral conditions observed, ranging from 1.4% (n=36) for fissured tongue to 0.1% (n=2) for bifid tongue. Other findings detected were torous platinus (1.3%; n=34), mandibular tori (0.1%; n=2) aphthous ulcer (0.4%; n=10), herpes simplex (0.3%; n=7), frictional hyperkeratosis (0.9%; n=23), melanosis (0.6%; n=14), lichen planus (0.3%; n=9) and nicotinic stomatitis (0.5%; n=13). The findings of this study provide information on the types and prevalence of oral lesions among Saudi dental patients. This provides baseline data for future studies about the prevalence of oral lesions in the general population. (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 The Saudi Thoracic Society (STS launched the Saudi Initiative for Chronic Airway Diseases (SICAD to develop a guideline for the diagnosis and management of chronic obstructive pulmonary disease (COPD. This guideline is primarily aimed for internists and general practitioners. Though there is scanty epidemiological data related to COPD, the SICAD panel believes that COPD prevalence is increasing in Saudi Arabia due to increasing prevalence of tobacco smoking among men and women. To overcome the issue of underutilization of spirometry for diagnosing COPD, handheld spirometry is recommended to screen individuals at risk for COPD. A unique feature about this guideline is the simplified practical approach to classify COPD into three classes based on the symptoms as per COPD Assessment Test (CAT and the risk of exacerbations and hospitalization. Those patients with low risk of exacerbation (<2 in the past year can be classified as either Class I when they have less symptoms (CAT < 10 or Class II when they have more symptoms (CAT ≥ 10. High-risk COPD patients, as manifested with ≥2 exacerbation or hospitalization in the past year irrespective of the baseline symptoms, are classified as Class III. Class I and II patients require bronchodilators for symptom relief, while Class III patients are recommended to use medications that reduce the risks of exacerbations. The guideline recommends screening for co-morbidities and suggests a comprehensive management approach including pulmonary rehabilitation for those with a CAT score ≥10. The article also discusses the diagnosis and management of acute exacerbations in COPD.

Medico-legal tasks are not exclusive to forensic medical experts -any physician may face medico-legal issues in his career. Hence, the practice of medicine requires education in legal issues. In Saudi Arabia, there are 30 universities with medical colleges, but we do not know how they teach undergraduate forensic medicine and medico-legal issues. The aim of this study was to discover undergraduate training courses in forensic medicine in Saudi universities. We conducted a cross-sectional study involving all colleges of medicine in Saudi Arabia. A structured, self-administered questionnaire containing 13 items relating to the undergraduate forensic medicine course was distributed. Out of a total of 30 universities, 27 universities responded. Of these 27 universities, 16 (59.26%) teach forensic medicine to undergraduate medical students, and 11 (40.74%) do not teach forensic medicine in their undergraduate curriculum. Of the 27 universities that responded, none has a department of forensic medicine. Eleven universities that do not teach forensic medicine have no forensic medicine unit/division or faculty at all. Forensic medicine belongs to the pathology department in 11 universities, while it belongs to different departments in five universities. There is variation in teaching methods, years where the course is taught and length of the course. Practical and morgue visits take place in 7/16 (43.8%) universities, while 9/16 (56.3%) universities only teach the theoretical aspects of forensic medicine. All 16 universities teach forensic medicine only to medical students and do not teach it to students in other colleges such as dentistry and nursing. PMID:27354384
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 within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease.

The aim of this study was to correlate the risk of PPD with obstetric and demographic variables in Saudi females. Materials and methods: Data were collected by interviewing females 8–12 weeks postpartum. PPD symptoms were defined as present when subjects had an Edinburgh Postnatal Depression Scale score of 10 or higher. Variables included in this study were age, education, occupation, parity, baby's sex, pregnancy period, delivery type, hemoglobin level, anemia, and iron pills taken during pregnancy. Results: Of the 352 postpartum females, the prevalence of PPD symptom risk was 117 (33.2%. Among the PPD symptomatic females, 66 (39.8% had low hemoglobin levels, and 45 (40.5% females were anemic during pregnancy (P≤0.05. These results suggest that early postpartum anemia, indicated by low hemoglobin level, is a significant risk factor for PPD (adjusted odds ratio 1.70, 95% confidence interval 1.05–2.74; P=0.03. Other variables, including age, parity, education, occupation, and delivery type, were not significantly correlated (P=0.15–0.95, but marginally indicative of the risk of depressive symptoms. Conclusion: Low hemoglobin level and anemia during pregnancy were risk factors for PPD in Saudi females. Many other factors may be considered risk factors, such as age, occupation, and parity. Anemic women need more attention and to be checked regarding their PPD, and treated if necessary. Keywords: postpartum depression, hemoglobin level, anemia, EPDS

Objective was to explore the hematologic risk factors for stroke in cohort of Saudi children. We evaluated children at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Investigations for suspected cases included neuroimaging, transcranial Dopppler (TCD) for cases of sickle cell diseases (SCD), and Duplex scan. Hemostatic assays included coagulation screening tests, tests of thrombin generation and fibrinolysis, coagulation inhibitors, and activated protein C resistance. During the study period, 104 Saudi children (aged one month to 12 years) with stroke were seen. The mean age of the cohort was 27.1 months (SD=39.3 months) and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). A major risk factor was identified in 93 of 104 cases of stroke (89.4%). Hematologic disorders were the most common (46.2%), followed by prothrombic disorders (31.7%); microcystic hypochromic anemia (26%); sickle cell disease (SCD), or SCB-thalassemia, (11.5%), and factor IX deficiency (2.9%). Raised anticardiolipin antibodies (13/49, 26.5%) was the most frequent abnormality. Deficiencies of the natural anticoagulants (protein S, protein C and antithrombin III) were as follows: protein S (15/70, 21.4%); protein C (15/70,21.4%) and combined deficiency of 2 or more inhibitors (9/70, 12.9%). Activated protein C resistance has not been detected. Contrary to the findings of previous studies from Saudi Arabia, SCD is a common risk factor and is severe, as it resulted in multiple strokes. Moyamoya syndrome was diagnosed in 2 patients with SCD, one of whom had revascularization surgery (encephaldoduroarteriosynangiosis). Assessment of children with SCD at a risk of stroke was helped by the introduction of TCD followed by neuroimaging, using MRI and magnetic resonanceangiography

Descriptive statistics were used to report the results.Results: The responses indicated inadequate health-related practices in the surveyed group: 22.2% brushed their teeth twice daily, 73.6% never flossed their teeth, and while 80.2% visited a physician in the past year, only 12.6% visited a dentist during the same year. Of the respondents, 94.8% reported that they had never received advice on oral hygiene tasks in relation to diabetes from a health professional. Awareness about the diabetes and periodontal disease association was limited: 46.7% knew that diabetics have gum problems more often if their blood sugar stays very high, and only 21.8% knew that gum disease makes it harder to control blood sugar in diabetic patients. A significant association (P<0.05 was found between a higher level of education and greater general and oral awareness, as well as a significant association (P<0.05 between longer duration of disease, regular exercise, and regular visits to the physician and awareness about diabetes mellitus. Additionally, a significant association (P<0.05 was found between regular dental visits and both periodontal disease and diabetes awareness. Family and friends were the main source of
The Ablah sedimentary succession represents a molasse basin in the Neo-Proterozoic Shield of Saudi Arabia. A rhyolite flow interbedded in the succession has been dated by the Pb/Pb method at 641± 1 Ma, indicating that the basin is a local expression of Panafrican tectonism in the south of the shield. Consequently, the Panafrican phase that has previously been described in the north can now be extrapolated to the south of the shield. This age determination also enables post-Panafrican events, which differ between the south and the north, to be analysed over the entire shield. (authors)

Subjects: The subjects included in this study were 58 patients with asthma, 47 patients with rhinitis and 112 patients with urticaria. They all gave clinical history suspecting food as causing or aggravating their symptoms. Methods: Specific IgE antibodies to different food allergens were measured in the patients serum by using the Pharmacia CAP Radioaller gosorbent (RAST Fluoroimmunoassay (FEIA test. Results: IgE-antibodies specific for different foods were detected in 38 (17.5% out of 217 patients. Most positive reactions were detected in urticaria patients (9.7% followed by asthmatic patients (5.5% and allergic rhinitis (2.3%. Reactions to peanut (22.6%, egg white (14.5 and cow′s milk (12.9% were very prominent. Conclusion: The prevalence rate of food allergy seems to be high in Saudi patients when compared to studies from other regions. The pattern of food reactions, detected in this study, can be utilized in diagnosis of patients with suspected food allergy. Further studies will be required to obtain more information about the prevalence and incidence rates among different patient groups.
Full Text Available Remote projects have their unique problems that are caused mainly by the remoteness of the project itself thus the loose control over management. This is due to a number of reasons such as lack of human resources and infrastructure. Research studies that were undertaken worldwide - regarding this issue- has highlighted few unique management problems. The aim of this paper is to investigate how far the IT tools would help in managing remote construction projects in the Kingdom of Saudi Arabia (KSA. Due to the lack of previous research regarding remote projects within the Gulf region and the KSA, a pilot study was conducted in 2009 to define and test the wording of questions that are part of the main survey. The main survey was undertaken on Saudi Electric Company (SEC. The study found that IT systems and tools have the potential but this potential is hindered by a number of technical, managerial, staff factors. Therefore, successful application of IT systems would require changes to the present management settings at various levels. This would ensure that the SEC is capable of achieving the full benefit from using these advanced systems.
Full Text Available Blooms of Noctiluca scintillans are reported for the first time in the Red Sea offthe south-western coasts of Saudi Arabia. During the present study, surface water samples werecollected weekly on the coasts of the Al Shuqayq region from February to April 2004-2006. The abundance of N. scintillans correlated negatively with most nutrients,as well as the cell densities of diatoms and dinoflagellate species. Microscopic examination of live cells from Noctiluca blooms showed the presence of some species of diatoms and dinoflagellates within the Noctiluca body - confirmation of its grazing on these microalgae algae. Thepresence of a Noctiluca bloom in the coastal waters off south-western Saudi Arabia could be linked indirectly to water eutrophication by an increase in prey abundance.The physico-chemical properties of Red Sea coastal waters should therefore be monitored regularly in order to minimize the formation of harmful algal blooms, which may affect all food web levels, including the human level.

The most likely environmental impact of concentrate discharges (in most instances twice the concentration of the ambient environment) leaking from desalination plants on local marine ecosystems has been controversially discussed for many years. Increasing water demand and lack of renewable natural water resources in Saudi Arabia also result in greater dependence on desalination and consequently amplify the impact on marine environment and multifactorial ecosystems in near-field areas of desalination discharges. Accurate scientific baseline data should furnish information on various factors such as intake- and outfall locality, brine (concentrate) discharge and chemical characteristics (i.e. effluent concentration, mass flow rates (flux)), local effects, and even cumulative effects of desalination activities, at least on a regional and even on a national scale. Even if such data were available, in many cases they are non-transparent and are not even accessible, or tend to be overlooked as a result of ambiguous desalination-related policies. This paper focuses on national environmental regulations in the Kingdom of Saudi Arabia (KSA) and how such regulations help control the flow of concentrate discharge into the receiving waters. © 2013 Desalination Publications.

Full Text Available Abstract Background Quality of work life (QWL has been found to influence the commitment of health professionals, including nurses. However, reliable information on QWL and turnover intention of primary health care (PHC nurses is limited. The aim of this study was to examine the relationship between QWL and turnover intention of PHC nurses in Saudi Arabia. Methods A cross-sectional survey was used in this study. Data were collected using Brooks’ survey of Quality of Nursing Work Life, the Anticipated Turnover Scale and demographic data questions. A total of 508 PHC nurses in the Jazan Region, Saudi Arabia, completed the questionnaire (RR = 87%. Descriptive statistics, t-test, ANOVA, General Linear Model (GLM univariate analysis, standard multiple regression, and hierarchical multiple regression were applied for analysis using SPSS v17 for Windows. Results Findings suggested that the respondents were dissatisfied with their work life, with almost 40% indicating a turnover intention from their current PHC centres. Turnover intention was significantly related to QWL. Using standard multiple regression, 26% of the variance in turnover intention was explained by QWL, p 2 = .263. Further analysis using hierarchical multiple regression found that the total variance explained by the model as a whole (demographics and QWL was 32.1%, p Conclusions Creating and maintaining a healthy work life for PHC nurses is very important to improve their work satisfaction, reduce turnover, enhance productivity and improve nursing care outcomes.
Dust particles affect both solar and terrestrial radiation by scattering and absorption and are therefore considered to be a significant climate-forcing factor. Dust storms are a very frequent phenomenon in Saudi Arabia. Several dust storm events occurred in Tabouk, northern region of Saudi Arabia, during the period between 2014-2015. In this study, simulations using the SMART model were conducted to investigate how the dusty conditions affected the solar irradiances during these events. Additionally, theoretical simulations were carried out using MODTRAN program to examine the changes in the infrared sky temperature during dusty conditions. The Atmospheric Optical Depth (AOD) measurements at (500 nm) were used as an input into both programs. The analysis showed that the dusty conditions significantly decrease the global and direct irradiances and increase the diffuse component compared with clear sky days. Also it was found that the dust storms increase the sky temperature in the atmospheric window (8-14 μm) such that the window emissions resembled those of a blackbody and the atmospheric window was almost closed.

Full Text Available The professional content of sleep medicine has grown significantly over the past few decades, warranting the recognition of sleep medicine as an independent specialty. Because the practice of sleep medicine has expanded in Saudi Arabia over the past few years, a national regulation system to license and ascertain the competence of sleep medicine physicians and technologists has become essential. Recently, the Saudi Commission for Health Specialties formed the National Committee for the Accreditation of Sleep Medicine Practice and developed national accreditation criteria. This paper presents the newly approved Saudi accreditation criteria for sleep medicine physicians and technologists.
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)

In this study we assessed the current status of coral reefs along the Saudi Arabian coast of the Red Sea. Among the three growth forms of Acroporid corals, the branching forms were found to dominate in the Farassan Islands (44.55%±11.10%cover) fol-lowed by tabular forms in the Doga Islands (ranging between 18%±6.47% and 18.30%±9.47% cover). Digitate forms were rarely found along the coast except at Maqna. Among the five growth forms of non-Acroporid corals, we observed maximum cover of branching forms in the Yanbu offshore area (58.89%±15.11% cover) followed by the Jeddah coast (24.76%±14.04% cover). The Millepora spp., a non-Scleractinian coral, was abundant at all the near-shore sites, such as Jeddah (10.70%±8.21%) and Al-Wajh (9.81%±6.69%). The live coral cover (including both Scleractinian and non-Scleractinian corals) of Saudi Red Sea coast was seen to be higher in the north and gradually decrease towards the south. Principal Component analysis showed that the contribution of Acro-porid corals was greater in the southern region than in the northern and middle regions, but vice-versa in the case of non-Acroporid corals. Bray-Curtis cluster analysis categorized all the study sites into two major clusters with 60% similarity. Among them, one cluster-forming sites from Maqna to Masturah (Northern region) and the second one comprised the middle and southern regions (Jeddah to Farassan Islands), and one outlier Rabigh.

Many arid and semi-arid regions have sparse precipitation observing networks, which limits the capacity for detailed hydrological modelling, water resources management and flood forecasting efforts. The objective of this work is to evaluate the utility of relatively high-spatial resolution rainfall products to reproduce observed multi-decadal rainfall characteristics such as climatologies, anomalies and trends over Saudi Arabia. Our study compares the statistical characteristics of rainfall from 53 observatories over the reference period 1965-2005, with rainfall data from six widely used gauge-based products, including APHRODITE, GPCC, PRINCETON, UDEL, CRU and PREC/L. In addition, the performance of three global climate models (GCMs), including CCSM4, EC-EARTH and MRI-I-CGCM3, integrated as part of the Fifth Coupled Model Intercomparison Project (CMIP5), was also evaluated. Results indicate that the gauge-based products were generally skillful in reproducing rainfall characteristics in Saudi Arabia. In most cases, the gauge-based products were also able to capture the annual cycle, anomalies and climatologies of observed data, although significant inter-product variability was observed, depending on the assessment metric being used. In comparison, the GCM-based products generally exhibited poor performance, with larger biases and very weak correlations, particularly during the summertime. Importantly, all products generally failed to reproduce the observed long-term seasonal and annual trends in the region, particularly during the dry seasons (summer and autumn). Overall, this work suggests that selected gauge-based products with daily (APHRODITE and PRINCETON) and monthly (GPCC and CRU) resolutions show superior performance relative to other products, implying that they may be the most appropriate data source from which multi-decadal variations of rainfall can be investigated at the regional scale over Saudi Arabia. Discriminating these skillful products is
Full Text Available The objective of this study was to find out the prevalence, characteristics, and distribution of musculoskeletal pain among construction workers in Saudi Arabia. A questionnaire about musculoskeletal pain in different parts of the body was completed by 165 construction workers from the construction industries in Dammam and Riyadh cities. The descriptive data were analyzed using chi-square test. The level of statistical significance was set at P<0.05. Eighty (48.5% of the responding workers had pain in neck, shoulders, lower back, hand, knee, or ankle. The majority of respondents had low back pain (50% followed by knee pain (20%. The average intensity of pain at all sites during activity and rest was 6.65 and 3.59, respectively. Thirty-four (42.5% respondents had dull aching pain and 24 (30% had cramping pain. There was an association between years of experience, duration of break during work, and use of protective equipment with the prevalence of musculoskeletal pain in construction workers (P<0.05. Most of the workers complaining of pain got medical treatment (62.5% and only 25% received physical therapy. It can be concluded from this study that the prevalence of musculoskeletal pain among construction workers in Saudi Arabia is high.
Beneath the harsh deserts of Saudi Arabia lie dark chambers and complex mazes filled with strange shapes and wondrous beauty. Radon concentration measurements have been carried out in the desert caves of Al-Somman Plateau in the Eastern Province of Saudi Arabia. Passive radon dosimeters, based on alpha particle etch track detectors with an inlet filter, were used in this study. A total of 59 dosimeters were placed in five caves for a period of six months. Out of 59 dosimeters, 37 could be collected for analysis. Measurements showed significant variations in radon concentrations in caves depending upon their natural ventilation. The results of the study show that the average radon concentration in the different caves ranges from 74 up to 451Bqm-3. The average radon concentration in four of the caves was low in the range 74-114Bqm-3. However, one cave showed an average radon concentration of 451Bqm-3. Radon is not a problem for tourists in the majority of caves. However, sometimes it may imply some limitation to the working time of guides

The present study was conducted to investigate the prevalence of musculoskeletal disorders and eye and vision complaints among the computer users of King Abdulaziz University (KAU), Saudi Arabian Airlines (SAUDIA), and Saudi Telecom Company (STC). Stratified random samples of the work stations and operators at each of the studied institutions were selected and the ergonomics of the work stations were assessed and the operators' health complaints were investigated. The average ergonomic score of the studied work station at STC, KAU, and SAUDIA was 81.5%, 73.3%, and 70.3, respectively. Most of the examined operators use computers daily for ≤ 7 hours, yet they had some average incidences of general complaints (e.g., headache, body fatigue, and lack of concentration) and relatively high level of incidences of eye and vision complaints and musculoskeletal complaints. The incidences of the complaints have been found to increase with the (a) decrease in work station ergonomic score, (b) progress of age and duration of employment, (c) smoking, (d) use of computers, (e) lack of work satisfaction, and (f) history of operators' previous ailments. It has been recommended to improve the ergonomics of the work stations, set up training programs, and conduct preplacement and periodical examinations for operators. PMID:25383379
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.
BK human polyomavirus (BKV) causes an asymptomatic primary infection in children, but later, establishes latency mainly in the urinary tract. Virus-host interactions influencing persistence and pathogenicity are not well-understood. We present here a 12-year-old Saudi boy, who had renal transplant in Egypt. Seven months later, he was admitted to our Pediatric Nephrology Unit as a case of renal impairment. He developed BKV infection, diagnosed and successfully managed in our hospital. This case demonstrates the expanding clinical importance of BKV in a post renal transplant patient. This virus can be detected in transitional cells in the urine (decoy cells) using cytology. Testing for BKV deoxyribonucleic acid in urine and blood is an early detection assay, and can be used as a screening test in the early stages. The early reduction of immunosuppression can improve the prognosis. No specific antiviral treatment has been established yet. This is the first report of detecting BK virus in a Saudi post-transplant child in urine and blood specimens by using polymerase chain reaction. (author)

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

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 Background: dyslipidemia and obesity are key independent modifiable risk factors for many non communicable chronic diseases. Patterns of association between these factors may help prevention and control. This study aims to assess the association between lipids profile and obesity among adults in Kingdom of Saudi Arabia and identify anthropometric predictors of dyslipidemia.Methods: data were collected and analyzed from a cross-sectional study using WHO STEPwise approach that included 4 990 Saudi adults aged 15- 64 years selected by stratified, multistage, cluster random sampling technique. Lipid profiles (cholesterol categories and triglycerides were determined spectrophotometrically by colorimetric biochemical methods. Obesity was determined by calculation of body mass index (BMI=Kg/m2, waist and hip circumferences and ratio and waist to height ratio.Results: the overall prevalence of obesity ranged from 33.8 to 44.4 % and the overall dyslipidemia prevalence ranged from about 25 to 44% depending on type of dyslipidemia and anthropometrics used. Prevalence of dyslipidemia and mean concentration of lipids profile were generally significantly higher in obese than non obese. The indicator waist/height ratio was the significant predictor for all types of dyslipidemia and all levels of serum lipids.Conclusions: the prevalence dyslipidemia and obesity are high and they are positively associated. Waist/height ratio was the most important predictor of dyslipidemia among adults.

Full Text Available Context: Epidemiological studies have shown that vitiligo is a complex trait, involving combinations of pathogenic effects of multiple susceptibility genes as well as environmental risk factors. Aim: To observe whether consanguinity increased the incidence of vitiligo in Saudi patients from Arar. Patients and Methods: This study included 69 Saudi patients with vitiligo and their families. These patients, selected from the experience specialist dermatology center in Arar, from April 2011 to 2012, were interviewed by a dermatologist to confirm the diagnosis and complete a questionnaire. Results: A total of 69 patients, 40 males and 29 females were selected. Their mean age was 34.5 ± 11.8 years with the median age of 23 years. The mean age at onset of disease was 27.9 ± 12.9 years. The mean duration of the disease was 9.7 ± 5.3 years. The frequency of focal, vulgaris, universal, and acrofacial subtypes was 22 (31.9%, 21 (30.4%, 8 (11.6%, and 18 (26.1%, respectively. A positive family history of vitiligo was obtained in 45 (65.2% cases. A comparison of the frequency of vitiligo among siblings in relation to the general population was more in accord with the multifactorial model. Conclusion: Consanguinity in marriage increases the incidence of the disease. Therefore, genetic counseling and premarital examination would be important contributions to lower the prevalence of vitiligo.

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 Influenza viruses are responsible for the influenza outbreaks that lead to significant burden and cause significant morbidity and mortality worldwide. Based on the core proteins, influenza viruses are classified into three types, A, B, and C, of which only A and B cause significant human disease and so the vaccine is directed against these two subtypes only. The effectiveness of the vaccine depends on boosting the immune system against the serotypes included within it. As influenza viruses undergo periodic changes in their antigen, the vaccine is modified annually to ensure susceptibility. In contrast to other countries, Saudi Arabia faces a unique and challenging situation due to Hajj and Umrah seasons, when millions of people gather at the holy places in Mecca and Madinah, during which influenza outbreaks are commonly found. Such challenges making the adoption of strict vaccination strategy in Saudi Arabia is of great importance. All efforts were made to develop this guideline in an easy-to-read form, making it very handy and easy to use by health care workers. The guideline was designed to provide recommendations for problems frequently encountered in real life, with special consideration for special situations such as Hajj and Umrah seasons and pregnancy.

Full Text Available Objective: To estimate the awareness of cardiovascular disease (CVD and their determinants in a screening campaign in the eastern province of Saudi Arabia. Materials and Methods: All national residents in the eastern province of Saudi Arabia aged 30 years and above, were invited to participate in a screening campaign for the early detection of diabetes and hypertension at more than 300 examination posts throughout the eastern province. A pre-structured questionnaire was designed to collect data on age, gender, marital status, education level, occupation, lifestyle habits, and history of heart attack, angina, arterial disease, stroke, and transient ischemic attack. Weight, height, blood pressure, and glucose concentration were measured. Results: Out of 197,681 participants, 5372 (2.7% were aware of a history of a CVD. The prevalence correlated well with age. It was higher in women, widows, and subjects with lower level of education. More than 75% of affected subjects had two or more risk factors. Conclusion: A substantial proportion of those with a history of CVD had multiple risk factors, necessitating an effective, focused policy for the prevention and treatment. Increased effort is required to promote an awareness of cardiac disease and also probably target primary care providers involved in the screening process.

To assess the breast cancer knowledge level of Saudi female school students.A detailed questionnaire on cancer breast was designed with all the needed information. Using a map of the Jeddah area of Saudi Arabia, schools were identified in each area and permission was sought from the Ministry of Education to distribute the questionnaire to the students. A team of volunteers was instructed on how to distribute and collect the questionnaires. The collected questionnaires were then statistically analyzed. This Pilot study of 500 students was performed in King Abdul-Aziz University Hospital using high schools from the city of Jeddah between April and June 2009. The results were used to build up a base for designing a community educational program. Analysis of the data from 337 questionnaires from high school and college students showed that the level of knowledge of young females on breast cancer is limited. However, it also indicated that the students are very enthusiastic to learn about cancer breast, and its prevention. The limited knowledge level of breast cancer in the younger generation might be an obstacle to screening programs and early diagnosis. Awareness programs should be developed including lectures, seminars workshops, and on hands training (Author).

Many natural products from plants have been identified to exert anticancer activity. It might be expected to be a challenge to look at the Saudi plants in order to discover new sources for new molecules which may have anticancer activity. The methanolic extracts of forty species of plants traditionally used in Saudi Arabia for the treatment of a variety of diseases were tested in vitro for their potential anticancer activity on different human cancer cell lines. The cytotoxic activity of the methanolic extracts of the tested plants were determined using three human cancer cell lines, namely, breast cancer (MCF7), hepatocellular carcinoma (HEPG2), and cervix cancer (HELA) cells. In addition, human normal melanocyte (HFB4) was used as normal nonmalignant cells. Sulforhodamine B colorimetric assay was used to evaluate the in vitro cytotoxic activity of the different extracts. The growth inhibition of 50% (IC(50)) for each extract was calculated from the optical density of treated and untreated cells. Doxorubicin, a broad-spectrum anticancer drug, was used as the positive control. Nine plant extracts were chosen for further fractionation based on their activity and availability. Interesting cytotoxic activity was observed for Hypoestes forskaolii, Withania somnifera, Solanum glabratum, Adenium obesum, Pistacia vera oleoresin, Caralluma quadrangula, Eulophia petersii, Phragmanthera austroarabica, and Asparagus officinalis. Other extracts showed poor activity. PMID:21953271

The current study was aimed to assess Saudi school students’ knowledge, attitude and practice about medicines. A pretested self-administered questionnaire was used anonymously among 15–20 year-old adolescents attending tertiary schools in Taif City, KSA. A total of 1022 students completed the questionnaires. Only 15.4% of the respondents knew the medicines’ uses. Most of the students 79.6% affirmed that they used to take medicines after consulting physicians, and 45.1% of the students thought that tablet size affects the medicine’s efficacy. More than half of the students knew that high temperatures affect the efficacy of medicines, there was a significant difference between rural and urban areas (P = 0.005). Physicians (50.6%) and community pharmacists (15.7%), were the main students’ reliable sources of information about medicines. The majority of the students 70.5% were interested in learning more about medicines. The younger students ⩽18 years wish to learn more than the older ones (P < 0.014). The study showed that Saudi school students aged 15–20 years old have poor knowledge, misconception and negative attitudes about medicines. Low level of knowledge may expose adolescents to health-related problems. Educational efforts are important to improve students’ practice toward medicines. PMID:25061406

Direct and total radiation measurements carried out over several years in Dhahran, Saudi Arabia in support of the Research Institute's solar energy programs have indicated a relatively large diffuse radiation component. This is primarily due to airborne particulates carried aloft by the prevailing winds in a desert environment and occurs particularly during the Shamal (north wind) sandstorm season. As a first step in quantifying the nature of this atmospheric turbidity, spectral beam solar radiation measurements for the period July 1980 to June 1981 were made in Dhahran, Saudi Arabia (Lat. 26/sup 0/ 23', Long. 50/sup 0/ 00'), using broad-band filter techniques. Schott filters (OG1, RG2 and RG8) arranged on an automatically rotated disk mounted on an Eppley Normal Incidence Pyrheliometer were used for the measurements. The Beer-Lambert relation was used to calculate optical depths from which values of the Angstroem Coefficient of Turbidity, ..beta.., were obtained for the wavelength exponent, ..cap alpha.. = 1.3. In addition, Herovanu's method was used to obtain ..cap alpha.. and ..beta.. values for each month. The 12-month average values of ..beta.. and ..cap alpha.. were 0.22 and 1.28, respectively. 12 references, 3 figures, 1 table.

Full Text Available Background. Physical activity (PA is associated with health benefits and disease prevention and is often prescribed in managing many health conditions. Understanding the cultural influences is relevant in order to effectively promote PA. The objective of this study was to assess the level of PA among Saudi women, measured by daily step count, and the association between PA and health beliefs. Methods. A total of 161 eligible participants were asked to complete two questionnaires to assess health beliefs: Health Locus of Control (HLC and Self-Efficacy Assessment Scale. Each participant was given a pedometer and a diary to record their daily PA for two weeks. Results. One hundred and five participants completed the two weeks pedometer data (mean age 26.3±7.1 years, BMI 25±4.2 kg/m2. The average pedometer score over two weeks was 5114±2213 steps. Step count had strong correlation with self-efficacy (rs=0.75, mild correlation with internal HLC (rs=0.42, and mild negative correlation with external HLC (rs=−0.35. Conclusion. The study demonstrates high level of inactivity among Saudi females in reference to the international recommendation for minimum activity. The data also reveal an association between PA and health beliefs. Ultimately, such information can be used to design gender- and culture-sensitive interventions that could enhance adherence to PA.

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.
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)

As a region renowned for high biodiversity, endemism and extreme temperature and salinity levels, the Red Sea is of high ecological interest. Despite this, there is relatively little literature on basic broad scale characteristics of the biodiversity or overall reef fish communities and how they change across latitude. We conducted visual transects recording the abundance of over 200 species of fish from 45 reefs spanning over 1000 km of Saudi Arabian coastline and used hierarchical cluster analysis to find that for combined depths from 0m-10m across this geographical range, the reef fish communities are relatively similar. However we find some interesting patterns both at the community level across depth and latitude as well as in endemic community distributions. We find that the communities, much like the environmental factors, shift gradually along latitude but do not show distinct clusters within the range we surveyed (from Al-Wajh in the north to the Farasan Banks in the south). Numbers of endemic species tend to be higher in the Thuwal region and further south. This type of baseline data on reef fish distribution and possible factors that may influence their ranges in the Red Sea are critical for future scientific studies as well as effective monitoring and in the face of the persistent anthropogenic influences such as coastal development, overfishing and climate change.

Full Text Available Energy and water are the two major need of the globe which need to be addressed for the sustenance of the human beings on this planet. All the nations, no matter most populous, developed and developing need to diversify the means and ways of producing energy and at the same time guarding the environment. This study aims at techno economical feasibility of producing energy using PV solar panels and utilizing it to pump-water at Dhahran, Riyadh, Jeddah, Guriat, and Nejran regions in Saudi Arabia. The solar radiation data from these stations was used to generate electricity using PV panels of 9.99 kW total capacity. Nejran region was found to be most economical in terms of minimal payback period and cost of energy and maximum internal rate of return whereas PV power production was concerned. Water-pumping capacity of the solar PV energy system was calculated at five locations based on the PV power production and Goulds model 45J series of pumps. Monthly total and annual total water pumping capacities were determined. Considering the capital cost of combined solar PV energy system and the pump unit a cost analysis of water pumping for a well of 50 m total dynamic head (TDH was carried out. The cost of water pumping was found to vary between 2 and 3 /m3.
Growing demand for science teachers in the Kingdom of Saudi Arabia, fed by increasing numbers of public school students, is forcing the Saudi government to attract, recruit and retain well-qualified science teachers. Beginning science teachers enter the educational profession with a massive fullfilment and satisfaction in their roles and positions as teachers to educating children in a science classroom. Nevertheless, teachers, over their early years of practice, encounter numerous challenges to provide the most effective science instruction. Therefore, the current study was aimed to identify academic and behavioral classroom challenges faced by science teachers in their first three years of teaching in the Kingdom of Saudi Arabia. In addition, new science teacher gender, school level and years of teaching experience differences in perceptions of the challenges that they encountered at work were analyzed. The present study also investigated various types of support that new science teachers may need to overcome academic and behavioral classroom challenges. In order to gain insights about ways to adequately support novice science teachers, it was important to examine new science teachers' beliefs, ideas and perceptions about effective science teaching. Three survey questionnaires were developed and distributed to teachers of both sexes who have been teaching science subjects, for less than three years, to elementary, middle and high school students in Al Jouf public schools. A total of 49 novice science teachers responded to the survey and 9 of them agreed to participate voluntarily in a face-to-face interview. Different statistical procedures and multiple qualitative methodologies were used to analyze the collected data. Findings suggested that the top three academic challenges faced by new science teachers were: poor quality of teacher preparation programs, absence of appropriate school equipment and facilities and lack of classroom materials and instructional

Protection of customers against monopoly is the first and main objective of the Saudi Electricity and Co-generation Regulatory Authority (ECRA). The second important objective, as recommended by the present study, is regulating natural monopoly businesses [Saudi electricity national grid (SENG) and Saudi electricity distribution (SED)] in addition to promoting real competition in competitive businesses [power supply providers (PSPs) and customer service providers (CSPs)]. Another four main objectives of ECRA are to promote the efficient use of energy and natural resources, to ensure a reasonable rate of return for PSPs and CSPs and at the same time to be fair to end-users, to ensure reasonable charges to SENG and SED services to be adequate for them to run the organization in a break-even manner and to maintain the system's security and reliability. The present paper discusses the way to improve and restructure the Saudi electricity market. (author)

The informatization practice of countries all over the world has shown that the level of a government's informatization is one main factor that can affect its international competitive power. At present, e-government construction is regarded as one of the most important tasks for the national economy and society upliftment and informatization in Saudi Arabia. Unlike the traditional governments, an e-government takes on a new look with its framework and operation mode more suitable for the contemporary era. In fact, it is a basic national strategy to promote Saudi Arabia's informatization by means of e-government construction. This talk firstly introduces the basic concepts and relevant viewpoints of egovernment, then reviews the development process of e-government in Saudi Arabia, and describes the current states, development strategies of e-government in Saudi Arabia. And also review e-government maturity models and synthesize them e-government maturity models are investigated, in which the authors have prop...

The symptoms of temporomandibular dysfunction (TMD), reported by 705 female university students of Riyadh, Saudi Arabia, are analysed. The population is representative of the educated class of Saudi Arabia. The most frequently reported symptoms were jaw feeling tired (34.5%), awareness of uncomfortable bite (31.3%), pain in front of the ear (22.4%) and discomfort upon wide opening (22.4%). The frequency of subjective reactions was, pain interferes with activity (42%), disturbed sleep (40.6%), taking of medication (27.8%) and pain being frustrating or depressing (26.8%). Some interesting relationships were found between the reported symptoms and marital status, residence and college of education. These findings are similar to those reported in a Bedouin community in Egypt, but lower than that in a Saudi Arabian population attending dental clinics, Saudi male dental students and high school students.

Measurement of indoor Concentrations were performed in Zulfi city of Saudi Arabia, using CR-39 track etch detectors. This investigation focused on the influence of different parameters, namely different locations, school categories, school building types, and room type as well as on the existence of differences in radon concentration at floor levels. We divided the Zulfi city into five regions, keeping in mind their geographical locations between Tuwaiq Mountains and Al-Thuwayrat sands. The measured average radon concentrations for regions 1-5 respectively are: 87.0±14.2 Bq/m3, 83.4±6.0 Bq/m3, 61.6±6.4 Bq/m3, 63.7±5.4 Bq/m3 and 87.5±6.Bq/m3 and the minimum concentrations are 28.0 Bq/m3, 5.5 Bq/m3, 1.1 Bq/m3, 1.0 Bq/m3 and 24 Bq/m3 respectively. These results are still within normal limits and below the action level of 148 Bqm-3 set by the U.S. Environmental Protection Agency (EPA). A test of significance using Minitab program was applied to investigate if radon levels in regions are significantly different from each other. We tried all combinations, and found the following results. The ''within regions''(different location) test yielded, region 2 is not significant versus region ''1''(p = 0.783) and versus region ''5''(P = 0.646), whereas it is significant versus region ''3''(P = 0.0160) and also versus region ''4''(p = 0.018). We investigated government and rented school's building also and none was found significantly different (p = 0.052). Floors of the same building were tested in order to examine the radon concentration as a function of storey level. No significant difference was observed at floor levels (p = 0.009). When girl's schools versus Boys and kindergartens schools were tested they were found significantly different. It is believed that this significant difference is due to geographical nature of the area, since most of the girl's schools were selected from regions 2 and 3, these regions are relatively close to the Tuwaiq mountains whereas other
