    2001-01-01

    Riyadh, the national capital of Saudi Arabia, is shown in 1972, 1990 and 2000. Its population grew in these years from about a half million to more than two million. Saudi Arabia experienced urbanization later than many other countries; in the early 1970s its urban-rural ratio was still about 1:3. By 1990 that had reversed to about 3:1. The city grew through in-migration from rural areas, and from decreases in the death rate while birthrates remained high. The 1972 image is a Landsat MSS scene; the 1990 image is a Landsat Thematic Mapper scene; and the 2000 image is an ASTER scene. All three images cover an area of about 27 x 34 km. The image is centered at 24.6 degrees north latitude, 46.6 degrees east longitude. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

  2. Knowledge and attitudes towards cardiopulmonary resuscitation among university students in Riyadh, Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was to assess the knowledge and attitudes towards cardiopulmonary resuscitation (CPR) among the students of King Saud University. This study was a cross sectional survey among King Saud University students, Riyadh, Kingdom of Saudi Arabia, which took place on December 17-20, 2006. The data was collected from self-administered questionnaires prepared in Arabic. The questionnaires were distributed to all 15 colleges of the university. Out of a study sample of 2250 students, 31% did not have prior CPR information. Of those with previous knowledge, 85% feel that it is inadequate. The most common sources of information were television and movies. The 12.7% of individuals encountered a situation that required the use of CPR. However, 14% of them performed it. This was mostly due to lack of knowledge (42.8%). Eighty-eight percent of students would like to learn how to perform CPR. Out of all King Saud University students, 45% believe that CPR training should be a graduation requirement. It was found that overall attitude towards CPR was positive. However, the knowledge on the topic was insufficient. Thus, more focus should be placed on the improvement of CPR skills. In addition, more studies are needed to assess knowledge and attitudes towards CPR in the community. (author)

    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 ?18O and ?D 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 ?18O and ?D 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 ?-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).

    2013-10-01

    The aim of this study was to investigate the learning style preferences of a group of first-year dental students and their relation to gender and past academic performance. A total of 113 first-year dental students (forty-two female, seventy-one male) at King Saud University in Riyadh, Saudi Arabia, participated. The Visual, Aural, Read-write, and Kinesthetic (VARK) questionnaire was used to determine the students' preferred mode of learning. This sixteen-item questionnaire defines preference of learning based on the sensory modalities: visual, aural, reading/writing, and kinesthetic. More than half (59 percent) of the students were found to have multimodal learning preferences. The most common single learning preferences were aural (20 percent) followed by kinesthetic (15.2 percent). Gender differences were not statistically significant. However, a statistically significant difference was found in the mean values of GPA in relation to the students' learning style preferences (p=0.019). Students with a single learning style preference had a lower mean GPA than those with multiple (quad-modal) learning style preferences. For effective instruction, dental educators need to broaden their range of presentation styles to help create more positive and effective learning environments for all students. PMID:24098042

    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.

    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

    To examine the recovered strains phenotypically, by conventional methods and genotypically by polymerase chain reaction (PCR), for direct detection of Staphylococcus aureus (S. aureus) 16S ribosomal Ribonucleic Acid (rRNA) gene (which serves as an internal control) and mecA gene. Secondly, introduce multiplex PCR targeting at the same time S. aureus 16S rRNA, Panton-Valentine Leucocidin (PVL), and staphylococcal cassette chromosome mec (SCCmec) type 4. Thirty-seven strains of S. aureus collected in 2007 from outpatient clinics in King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, were tested in the College of Pharmacy phenotypically by conventional methods and genotypically by PCR for direct detection of S. aureus 16S rRNA and mecA genes. All the 37 strains, were tested also by multiplex PCR targeting at the same time S. aureus 16S rRNA, PVL, and (SCCmec) type 4. Polymerase chain reaction detected all the 37 bacteriologically positive S. aureus (100%) and the mecA gene in all strains phenotypically resistant to methicillin (100%), at the same time it detected the mecA gene in 2 strains phenotypically sensitive to methicillin. Only 3 strains (8.1%) recovered from skin and soft tissue infections were positive for PVL and SCCmec type 4. The PCR assay can be used for rapid detection of S. aureus and mecA gene. At the same time the multiplex PCR assay explained in this study is a rapid, sensitive, and reliable test for direct detection of community-acquired methicillin-resistant S. aureus. (author)

    Full Text Available In this work, we present additional morphological data about the scorpion fauna of Saudi Arabia. This investigation was carried out in the central region (Riyadh) of the country and identified existing and newly discovered scorpion species for taxonomic documentation while determining the medically [...] important ones. The survey covered the entire Riyadh region, including all major districts, and collected a total of 4,164 specimens. Morphological identification of collected animals was based on identification keys. There were two species (one with a subspecies) that belonged to the family Scorpionidae, namely Scorpio maurus kruglovi (0.02%) and Hemiscorpius arabicus (0.05%). The latter, currently, is part of the Hemiscorpiidae family that had been upgraded from a subfamily. Eight more species from the Buthidae family were found: Leiurus quinquestriatus (7.20%), Androctonus crassicauda (17.24%), Androctonus bicolor (64.60%), Compsobuthus arabicus (3.84%), Compsobuthus werneri (0.94%), Buthacusyotvatensis nigroaculeatus (2.31%), Buthacusleptochelys (3.24%) and Orthochirus innesi (0.55%). The major locations of collection were the outskirts of Riyadh city and the airport vicinity. The specimens were transported from all central region areas in 124 short trips.

    2014-01-01

    Full Text Available Aim: This study aimed at assessing prevailing patterns and risk factors of tobacco consumption among clients, food handlers and employers of food facilities, in Riyadh, Saudi Arabia. Methods: A cross-sectional approach to a representative sample of food facilities in Riyadh was used. A sample of 3000 participants included clients (75%; food handlers/hospitality workers (20 % and employers (5 %. Participants were reached at restaurants, food courts or cafes. A modified version of the WHO-CDC-Global Youth Tobacco Survey questionnaire was used for data collection. Results: The prevalence of tobacco use at food facilities was found to be 40.3 %, of which 74% were customers, 18.8% were food handlers and 7.2% were managers. The consumption of tobacco was higher at restaurants (39.9%, but lowest at food courts of shopping malls. Water pipe (55.3% was the main consumption type, followed by cigarettes (42.6% and chewing tobacco (2.1%. Multivariate analysis showed that gender (male, marital status (single, and type of food facility (Estaraha and café/coffee shop were independent risk factors associated with tobacco use at food facilities. Conclusion: Tobacco use is very common in food facilities in Riyadh as reflected by results of our study, especially among single males Saudis. We should build on success encountered in banning smoking in airports, airplanes, shopping malls, market places, educational institutions and healthcare facilities, extending the ban to include food facilities as well. This is important for the health of non-smokers as well as smokers themselves.

    Background : Saudi Arabia has passed through lifestyle changes toward unhealthy dietary patterns such as high fast food consumption. Adolescents and young adults, particularly girls, are the main groups exposed to and affected by these adverse eating behaviors. Objective : The aim of this study was to examine the trends of fast food consumption among adolescent and young adult Saudi girls living in Riyadh, and to compare between them. Design : In a cross-sectional survey, 127 adolescent Saudi girls (13-18 years) and 69 young adult Saudi girls (19-29 years) were randomly recruited to participate in this study. Weight, height, waist circumference, and hip circumference were measured using standardized methods. Twenty-four-hour diet recall and a face-to-face interview food questionnaire were performed. Results : Most of the participants had adequate intake of protein, riboflavin, iron, and sodium, but exhibited low intake for several other nutrients. Among study participants, 95.4% consume restaurants' fast food and 79.1% eat fast food at least once weekly. Burgers and carbonated soft drinks were the main kinds of fast food meals and beverages usually eaten by girls. Adolescent girls who usually ate large portion sizes of fast food had significantly higher mean waist circumference and hip circumference. Participants eat fast food primarily for enjoying the delicious taste, followed by convenience. Restaurants' hygiene and safety standards were the main concern regarding fast food for 62.2% of girls. Finally, international restaurants were preferable by participants to buy fast food compared with local restaurants (70.9% vs. 29.1%). Conclusion : Our findings provide evidence on the high prevalence of fast food consumption among Saudi girls, suggesting an urgent need for community-based nutrition interventions that consider the trends of fast food consumption and targeted eating behaviors of adolescent and young adult girls.

    Full Text Available Background: Advertising is a crucial component of pharmaceutical industry promotion. Research indicates that information on advertisement materials might be inadequate, inaccurate, biased, and misleading. Objective: To analyse and critically assess the information presented in print pharmaceutical advertisements in Saudi Arabia.Methods: Pharmaceutical advertisements were collected from 280 community pharmacies in Riyadh city, Saudi Arabia. The advertisements were evaluated using criteria derived from the Saudi Food and Drug Authority (SFDA regulation, the World Health Organization (WHO ethical medicinal drug promotion criteria, and other principles reported in similar studies. The data were extracted independently by two of the researchers using a standardized assessment form. Results: One hundred eighty five printed advertisements were included in the final sample. Approximately half of the advertisements (n = 94, 51% were for over-the-counter (OTC medications, and 71 (38% were for prescription-only medication. Information such as the name of active ingredients was available in 168 (90.8% advertisements, therapeutic uses were mentioned in 156 (98.7% of analysed advertisements. Safety information related to side effects, precautions, and major interactions were stated in 53 (28.5%, 58 (31%, and 33 (16.5% advertisements, respectively. Only 119 advertisements (64% provided references for information presented. Conclusions: Our findings suggest that print advertisements do not convey all the information necessary for safe prescribing. These results have implications for the regulation of drug advertising and the continuing education of pharmacists.

    Attendees of 15 health centers in urban and rural areas in the Riyadh region were screened for obesity during May and June 1994. Systemic selection yielded 1580 Saudi males for analysis. The mean age was 33.6 +/- 13.5 years and body mass index (BMI) was 26.9 +/- 5.7 kg/m(2). Only 36.6% of subjects were their ideal weight (BMI 40 kg/m(2)). Middle age, lower education and joblessness predicted a higher risk for obesity. Patients living in a rural areas had greater BMIs than those living in urban areas (P diabetis mellitus, hypertension, stroke, heart disease, sleep apnea syndrome and osteoarthritis of the knees. Young parents who are at risk of developing obesity and who play a central role in perpetuating it in their offspring should be the target of obesity-prevention programs. PMID:17372433

    We investigated an outbreak of Middle East respiratory syndrome (MERS) at King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, during March 29-May 21, 2014. This outbreak involved 45 patients: 8 infected outside KFMC, 13 long-term patients at KFMC, 23 health care workers, and 1 who had an indeterminate source of infection. Sequences of full-length MERS coronavirus (MERS-CoV) from 10 patients and a partial sequence of MERS-CoV from another patient, when compared with other MERS-CoV sequences, demonstrated that this outbreak was part of a larger outbreak that affected multiple health care facilities in Riyadh and possibly arose from a single zoonotic transmission event that occurred in December 2013 (95% highest posterior density interval November 8, 2013-February 10, 2014). This finding suggested continued health care-associated transmission for 5 months. Molecular epidemiology documented multiple external introductions in a seemingly contiguous outbreak and helped support or refute transmission pathways suspected through epidemiologic investigation.

    Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus (MRSA is spreading worldwide and poses a serious public health problem, being present in hospital settings and communities. However, from the Middle East and the Arabian Peninsula few molecular typing data on MRSA strains are currently available. In order to obtain data on the population structure of MRSA in Riyadh, Saudi Arabia, 107 clinical and environmental MRSA isolates were genotyped using a microarray-based assay. Results Five major MRSA strains from four clonal complexes were identified CC8/ST239-III (20.75%, PVL-positive as well as -negative CC22-IV (18.87% and 9.43%, respectively, PVL-positive CC30-IV (12.26% and PVL-positive CC80-IV (17.92%. Minor strains, which accounted for less than 3% each, included CC1-IV/SCCfus, PVL-positive CC1/ST772-V, PVL-positive as well as- negative CC5-IV, CC5-IV/SCCfus, CC5-V, CC6-IV, CC45-IV, PVL-negative CC80-IV, PVL-positive CC88-IV, CC97-V and a CC9/ST834-MRSA strain. Conclusions Typing of MRSA strains from Riyadh revealed a high diversity of clonal complexes. The prevalence of the genes encoding the Panton-Valentine leukocidin was surprisingly high (54.21%, and a significant rate of resistance markers was detected also in strains considered as community-associated.

    Full Text Available Background: Tobacco consumption is associated with considerable negative impact on health. Health professionals, including future doctors, should have a leading role in combating smoking in the community. Objectives: The aims of the study were to assess the prevalence of smoking among medical students of newly established medical colleges in Riyadh city, the capital of Saudi Arabia, as well as to assess students? attitude, practice and their knowledge on the risk factors of tobacco consumption. Methods: A cross-sectional, questionnaire-based study of students from two medical colleges in Riyadh, Saudi Arabia was carried out. The questionnaire used was anonymous, self-administered and developed mainly from Global Adult Tobacco Survey (GATS. Results: A total of 215 students participated in this study. Forty students (19% indicated that they smoke tobacco at the time of the study. All of them were males, which raise the prevalence among male students to 24%. Tobacco smoking was practiced by males more than females (P value < 0.0001 and by senior more than junior students (< 0.0001. About 94% of the study sample indicated that smoking could cause serious illnesses. About 90% of the students indicated that they would advice their patients to quit smoking in the future and 88% thought that smoking should be banned in public areas. Forty-four students (20% thought that smoking has some beneficial effects, mainly as a coping strategy for stress alleviation. Conclusion: Despite good knowledge about the hazards of tobacco consumption, about 25% of the medical students in this study continue to smoke. The main reported reasons should be addressed urgently by policy-makers. Special efforts should be taken to educate medical students on the effective strategies in managing stress during their study as they thought that tobacco smoking could be used as a coping strategy to face such a stress.

The participants (n = 1830 self recorded their responses on the Global Youth Tobacco Survey questionnaire.Results: Lifetime prevalence of cigarette smoking was 35%, while 13% of students currently used other tobacco products. About 16% of students currently smoked at home, and 84% of students bought cigarettes without any refusal from storekeepers. Thirty-one percent and 39% of students were exposed to secondhand tobacco smoke inside and outside the house, respectively, which was definitely or probably harmful to health as opined by 87% of participants, and 74% voiced to ban smoking from public places. Among current smokers, 69% intended (without attempt to quit and 63% attempted (but failed to quit during the past year. Almost an equal number of students saw antismoking and prosmoking media messages in the last month, and 28% of students were offered free cigarettes by a tobacco company representative. In schools, more than 50% of students were taught about the dangers of cigarette smoking in the last year. Smoking by parents, older brothers, and close friends, watching prosmoking cigarette advertisements, free offer of cigarettes by tobacco company representatives, perception of smoking being not harmful, and continuing smoking which can be easily quit significantly increased the odds of smoking by students.Conclusion: The common use of tobacco in school populations needs to be addressed by, among other tobacco control measures, a strict ban on cigarette selling to minors and intensive regular tobacco control campaigns involving health and religious messages.Keywords: tobacco use, secondhand tobacco smoke, environmental tobacco smoke, intermediate school boys, Global Youth Tobacco Survey, Saudi Arabia

    Full Text Available Due to the arid climate of the Saudi Arabia, groundwater is a most precious natural resource, providing reliable water supplies for population of these areas. The main aim of this study is to evaluate the quality of groundwater resources in the selected study areas of Riyadh and Al-Ahsa regions. This study focuses on the chemical analysis of the available groundwater resources in these two areas of Saudi Arabia. The distribution of the chemical constituents (major, minor and trace elements is determined and compared with each other. The groundwater salinity as one primary indicator of water quality for irrigation was found to be moderately high in most studied water samples for both areas. Besides salinity, chloride makes these waters unsuitable for irrigation, affecting agricultural activities. However, boron and trace elements were within acceptable levels. Comparative study revealed that the Al-Ahsa groundwater is generally considered higher in its salinity, chloride, and sodium content than Riyadh groundwater. Generated piper diagrams revealed that the majority of investigated waters types in Al-Ahasa were sodium chloride - sulphate, however, in Riyadh the majorities were to calcium magnesium sulphate - chloride. The most important results of speciation calculations, computed by Phreeq model, are saturation indices for minerals, which indicate whether minerals should dissolve or precipitate. The results indicated that most studied water samples in Al-Ahsa were undersaturated for anhydrite, gypsum, and halite. However, in Riyadh most water samples were undersaturated for anhydrite and halite, and saturated for Gypsum.

    2016-02-01

    On March 2011, a severe damage has occurred to Fukushima Di-iachi nuclear reactor complex in Japan following the huge earthquake and the resulting Tsunami. Consequently, vast amounts of radioactive fallout were released into the atmosphere and contaminated the environment in Japan. Soon after the accident, traces of anthropogenic radionuclides were detected in environmental samples collected in many parts in the northern hemisphere even very far away from Japan creating a global concern. There is no information about radioactive contamination in the Arabian Peninsula caused by the Japanese Fukushima nuclear accident. The first evidence of Fukushima radioactive fallout in Riyadh (24° 43' N, 46° 38' E), Saudi Arabia has been confirmed in April 8, 2011. The airborne fission products (131)I, (134)Cs and (137)Cs were measured in air samples. The radionuclide concentrations were determined by identifying their characteristic gamma rays using a germanium detector. Their activity concentrations were studied as a function of time over a period of 20 days at the end of which they had mostly fallen below our limit of detection. The maximum activity concentration of (131)I, (134)Cs and (137)Cs in air of, respectively, 323.7 ± 18.5, 17.2 ± 1.0 and 26.0 ± 1.8 ?Bq m(-3) were observed on April 10-11, 2011. The (131)I/(137)Cs and (134)Cs/(137)Cs activity ratio values in air were presented and discussed. Finally, the effective doses to the public of Riyadh city from inhalation of (131)I, (134)Cs and (137)Cs due to contribution from Fukushima incident was found far below levels of concern.

  9. Indoor Fungal and Bacterial Contaminations on Household Environment in Riyadh, Saudi Arabia

    International Nuclear Information System (INIS)

    This study was conducted to determine the microbial and inhabitant of household environment in Riyadh, Saudi Arabia. Overall, a total of 180 samples were collected and analyzed for fungal growth, 160 house samples were obtained on BAP medium and PDA medium. The Eastern Riyadh region turned out with the highest fungal isolates with 15/61 (24.6%). Among the most common fungal isolates from bedroom carpets were Aspergillus niger (21.6%), Alternaria sp. (15.7%), Aspergillus flavus (15.7%) Candida sp. (11.8%), Cladosporium sp. (9.8%) and Rhizopus sp. (9.8%). Other fungal isolates from bedroom carpets included Penicillium sp (5.9%)., Cunninghamella sp.(3.9%), Rhodotorula sp.(3.9%) and Aspergillus terreus (1.9%) Overall relative densities from all specimens obtained from household carpets, bedroom walls and carpet stores showed Alternaria spp. as the most common fungal isolate (55.3%) followed by Aspergillus niger (29%), Aspergillus flavus (19.3%), Rhizopus spp. (9.7%) and Penicillium spp. (7.0%). Other fungal isolates such as Candida spp., Cladosporium spp., Cunninghamella spp., Rhodotorula spp. and Aspergillus terreus had less than 6% overall relative density. From 40 carpet specimens collected for microbial analysis, 20 (50%) showed bacterial growth. Bacillus spp. was the most common isolated organism (35%) followed by Staphylococcus epidermidis (10%), Epiococcus spp. (10%), Corynebacterium spp. (10%) and Bacillus polymyxa (10%). Other bacterial isolates included Bacillus subtilis, Pseudomonas aeruginosa, Bacteroides spp., Clostridium spp. and Staphylococcus aureus .The presence of these fungal and microbial pathogens poses risk for individuals. When possible, floor carpeting in homes should be minimized or avoided since this serves as habitats for opportunistic fungi and infectious agents that pose harm to one's health. (author)

    Full Text Available Background: Budd-chiari syndrome (BCS is rare disorder, varied in etiology, inconsistent in presentation, unpredictable in progression, and challenging in therapy. Aim of study: The aim of this study is to review experience of Budd-Chiari syndrome at KFSH, Riyadh; over a ten-year period. Methods: In a retrospective study using a computer data search of the medical records from May 1990 to May 2000, 43 patients? charts suspected of BCS were reviewed. 29 patients were found to have BCS, diagnosed by Doppler ultrasound, venography, MRI, or CT with or without liver biopsy. Findings: Of the 29 patients, 18 were male (62.1% and I 1 were female (37.9%; mean age was 35.4 (range 17-69 years. Nine patients had Behcet?s disease; seven patients had malignancy (five HCC, one melanoma and one hypernephroma. Eight patients had antiphospholipid syndrome, two patients had no known cause and three (one related to trauma, the other related to protein C deficiency and the third related nephrotic syndrome. Nineteen patients presented acutely with abdominal pain, progressive ascites and hepatomegaly. Ten patients had subacute presentation mimicking cirrhosis of liver. Five patients had web in the intrahepatic IVC or ostium HV and the remaining 24 patients had thrombosis of hepatic veins. Five patients received surgical shunts, three had balloon dilatation of webs, 11 had anticoagulant therapy and seven patients had symptomatic treatment. Eleven patients died, six of them had malignancy, two died while awaiting liver transplantation and three died with fulminant hepatic failure. Fourteen patients are still on follow-up. Conclusion: Budd Chiari syndrome in Saudi Arabia is related to a defined cause in majority of patients (92%. Behcet?s disease is a dominant cause of BCS in Saudi Arabia. This is in contrast to world literature where around 50% of patients are of unknown etiology

  11. Bacterial and Aspergillus spp. Contamination of Domestic Kitchens in Riyadh, Saudi Arabia

    International Nuclear Information System (INIS)

    A randomized sampling of 50 households in Riyadh City, Saudi Arabia was conducted to determine microbial and Aspergillus spp contaminants in domestic kitchens between May and June 2006. Samples were taken from open air in the kitchen and from used kitchen sponges. Inoculation procedures were varied from direct inoculation of the sponge into the medium to dilution of a cut portion of the sponge. A total of 200 samples were taken from which, 700 culture plates were done (BAP and Nutrient agar). Identification by the API system of identification (Analytical Profile Index, BioMerieux) revealed Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus epidermidis, Enterobacter cloacae, Diphtheroids and Bacillus cereus, Aspergillus spp. was isolated and identified microscopically. Among the isolates, Staphylococcus epidermidis , Staphylococcus aureus was isolated in 90% of the plates followed by Pseudomonas aeruginosa (83%) , Klebsiella pneumonia ; Bacillus cereus (63%).and Aspergillus spp (15%) These opportunistic pathogens may be harmful especially in immunocompromised hosts. In this setting, there is a constant risk of contamination and transfer to willing hosts, thus appropriate measures should be implemented such as the use of disposable sponges. (author)

    Full Text Available Forty five species belonging to nineteen genera of terrestrial fungi were recovered on glucose and cellulose Czapek?s media from one hundred and forty drinking water samples which, were collected from different kids (2 schools, primary (77 schools, mediatory (33 schools and secondary (28 schools schools from different regions in Riyadh city, Saudi Arabia. Cellulose Czapek?s (39 species related to 19 genera was rich than glucose Czapek?s (37 species belonging to 15 genera with the species diversity. Water samples collected from primary schools were the most contaminant with fungal populations as compared with other tested samples. Both Aspergillus and Penicillium contributed the broadest spectra of the isolated terrestrial fungal species where they were represented by eight and six species, respectively on the media of isolation. The most prevalent isolated species of terrestrial fungi on the two isolation media were; Cladosporium cladosporoides, Trichoderma viride, Curvularia lunata, Aspergillus niger, Emericella nidulans, Mucor circinelloides and Rhizopus rhizopodiformis. The majority of the isolated genera and species were almost similar on both of isolation media although several species were recorded in only one isolation medium.

  13. A preliminary study on HTGR with air-cooled condenser at Riyadh, Saudi Arabia

    International Nuclear Information System (INIS)

    N GNP reactor plant adopted a Rank in steam cycle for early deployment and for reducing R and D risk and cost. Original plant design is based on a wet cooling tower with wet bulb temperature of 34 .deg. C. This cooling environment may be sufficient for most area in North America. However, we should consider air temperature of 45 .deg. C and no available cooling water for any site near Riyadh, Saudi Arabia. A plausible option in such arid area is using an air-cooled condenser(ACC) which is widely used in a combined cycle plant in arid region. ACC is also suitable for freezing area such as northern territory or high elevation remote area. We have studied impact of the cooling method on the power generation efficiency and the annual average power production referencing N GNP steam turbine. Even though condenser split is assumed to be the same between ACC and wet cooling tower, large difference in air temperature and wet bulb temperature makes large efficiency loss in the ACC. The ACC efficiency is lower than that of the wet cooling tower by 1.12%. To make up this loss, we proposed the variable steam extraction rates operation. An air cooled condenser is a practical

    Full Text Available Background: Saudi Arabia used to be hyperendemic for HBV infection. Most of infection occurs in early life. HBV vaccine was, therefore, introduced in 1989 as the seventh primary immunogen of the EPI Program. This study is conducted to evaluate the efficacy of this program in Riyadh and Hail Regions. Method and Patients: A cohort follow-up study of children from Riyadh and Hail, who had been vaccinated in 1989, evaluated in 1991 and tested for HBV markers six years later. Results: The files of 303 children from Riyadh and Hail, who were investigated in 1991 retrieved and only 119, were available for testing. Fifty percent of the children have still a protective anti-HBs tittre. One vaccinated child was found to be positive for HBsAg. According to this study, the efficacy rate against HBsAg carriage is 88%. Conclusion: This study demonstrates the tremendous effect of HB vaccine on the HBV infection of Saudi children in these two regions

    Aljuwaiber, Mohammed A.

    Technology has improved many educational issues. This is a very exciting time for technology and education. The primary purpose of this study was aimed at understanding the impact of home computer use on academic achievement in the computer curriculum of the 12th grade students in Riyadh, Kingdom of Saudi Arabia. In particular, the study attempted to determine if the use of home computers would be an effective manner for increasing students' academic achievement. The participants of the study were 240 male and female students as a random sample from 12th grade from eight random high schools in Riyadh, Saudi Arabia. An achievement exam and survey were developed by the researcher based on the computer science curriculum topics, the quantitative data was collected in both a single achievement exam and a single survey from a sample of 240 Saudi high school students. Both the survey and an achievement exam were split equally between male and female students. The study sought the answer to 10 questions. Analysis of variance (ANOVA), followed by tests of simple main effects and post hoc comparisons using Scheffe, as well as Pearson Correlation were conducted to answer the research questions. The study results pointed out that home computers were important to support the students in their academic achievement in the computer science curriculum. Therefore, more attention must be given to the use of home computers for all students. Moreover, we should attempt to treat the difficulties which students face for getting computers in their homes.

    The purpose of this study was to describe the present status of geography education in boys' intermediate schools in Riyadh, Saudi Arabia as perceived by geography teachers and supervisors; that is, to investigate the objectives, content, methods of teaching, tools and resources that are available and used in classrooms, evaluation techniques, and problems encountered in the teaching of geography. To collect data from this representative sample population, a questionnaire was developed by the researcher specifically for this study. Questionnaire data was collected from 19 social studies supervisors and 213 geography teachers. Percentages, frequencies, means, and standard deviations were computed for each questionnaire item. Chi Square tests were applied to determine if any significant differences could be identified between the observed and expected responses of supervisors and teachers. Major findings of the study indicated that both supervisors and teachers tend to strongly support the identified geography objectives. Most teachers and supervisors also indicated that the current geography curriculum contains enough information about Saudi Arabia, the Arabic world, and the Islamic world. In addition, the also indicated that geography content promotes a sense of patriotism and cultural pride. Responses indicated that educators see deficiencies in the content: it does not focus sufficiently on current events nor on developing student skills such as research and technical skills like drawing maps. Lecture and discussion are the most commonly used strategies in the teaching of geography. Field trips, role-playing, scientific competitions, scientific games, solving problems, and individual learning are less commonly used. Teaching tools most commonly used are wall maps and earth globes, whereas the use of geographical transparencies, models, and instruments is not common. Most of the teachers do lot use computers in their teaching. Evaluation techniques depend completely on traditional examinations to evaluate the performance of the students. Chi-square test shows that there are significant differences in observed and expected frequencies between teachers and supervisors with respect to geography learning objectives, geography content, methods of teaching, tools and resources, and the problems that geography teachers encounter in their teaching.

    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.

    Full Text Available Abstract Background Although human parainfluenza type 2 (HPIV-2 virus is an important respiratory pathogen, a little is known about strains circulating in Saudi Arabia. Findings Among 180 nasopharyngeal aspirates collected from suspected cases in Riyadh, only one sample (0.56% was confirmed HPIV-2 positive by nested RT-PCR. The sample that was designated Riyadh 105/2009 was used for sequencing and phylogenetic analysis of the most variable virus gene; the haemagglutinin-neuramindase (HN. Comparison of HN gene of Riyadh 105/2009 strain and the relevant sequences available in GenBank revealed a strong relationship with Oklahoma-94-2009 strain. Phylogenetic analysis indicated four different clusters of HPIV-2 strains (G1-4. Twenty-three amino acid substitutions were recorded for Riyadh 105/2009, from which four are unique. The majority of substitutions (n=18 had changed their amino acids characteristics. By analyzing the effect of the recorded substitutions on the protein function using SIFT program, only two located at positions 360 and 571 were predicted to be deleterious. Conclusions The presented changes of Riyadh 105/2009 strain may possess potential effect on the protein structure and/or function level. This is the first report that describes partial characterization of Saudi HPIV-2 strain.

    The present investigation is a retrospective review of snake bites in Riyadh province over the period (2005-2010). A total of 1019 cases of bites admitted to the Ministry of Health medical centers in Riyadh province were analyzed on the basis of age, sex, time of bite and its site on the body, outcome of treatment, antiserum dose and type of snake. Bites occurred throughout the six years with the highest frequency in 2005 and least in 2006 where most of the bite cases were mild and all evolved to cure except four patients who died following the administration of antivenom during 24 h after snake bite. Most of the patients were males (81.7%) and the most attacked age was within the range of 11-30 years (51.5%). All the bites were mainly in the exposed limbs and the most frequently bitten anatomical regions were the lower limbs (427 cases, 41.9%), principally the feet. The study incriminates Cerastes cerastes gasperettii in most of the bites indicating it as the snake of medical importance in Riyadh province. Also, the study indicates low degree of threat in spite of high rate of snake bites as a result of the availability of the medical facilities and the antivenin use in medical centers in Riyadh province.

    Full Text Available This study focuses on the temporal monitoring and chemical analysis of two pathways, unpadded and open drain canal, of the surface industrials effluent on industrial city of Riyadh city, Saudi Arabia. The distribution of the chemical constituents (Major, Minor, and Heavy metals is determined and compared with Saudi Arabia and USEPA standards. The obtained results indicated that most collected water samples exceeded the acceptable limits set by standards used for most parameters determined. The concentrations of total suspended solids, Fe, Mn, Zn, Cd, Ni, Pb, Mo, As, B, NO3-, and NH4+ in industrial effluents decreases away from the point source of pollutions. On the other hand, the SAR , RSC, total hardness, and soluble ions (Ca2+, Mg2+,Na+, K+, Cl-, CO3 2-, HCO3-, and SO4 2-, remained constant. Most heavy metals on wastewater effulent were above permissible limits. On the other hand, the filtration of wastewater decreases the heavy metal concentrations to permissible levels. The highest average metals concentration in digested effluents for deferent locations and sampling periods were Fe (17.1 mg/L followed by Mo (11.6 mg/L, then Co (0.03 mg/L. However the Mo recorded the highest value in filtrated effluents (23.2 ug/L followed by Fe (21.6 ug/L, and then Cd (8.02 ug/L. The monitoring of wastewater heavy metals concentrations (determined on filtrate for both pathway recorded that the concentration of Fe, Mo, Zn, Cd, Pb, As, Ni, and Mn decreased from (60-100 ug/L at point sources to be (5-10 ug/L at 1000 m from point sources, however no clear behavior was recorded for Cu and Co. Moreover the concentrations of all heavy metals by the last sampling point on downstream were remained at 10 ug/L or less. The study emphasis that continuous application of industrial wastewater on Riyadh environment will lead to more accumulation of heavy metals in the soil and natural plants, and also high possibilities of groundwater contamination by nitrate.

  17. Determination of some Heavy Metals in the Soils of Schools Playground in Riyadh, Saudi Arabia

    International Nuclear Information System (INIS)

    The determination of the total content of fifteen elements in soil samples collected from 29 different schools playgrounds in Riyadh metropolitan environment was carried out by inductively coupled plasma mass spectrometry (ICP-MS) combined with microwave digestion technique. According to the results of the concentration at 29 school's playgrounds in the selected districts, the average concentrations of the heavy metals were determined at 25.91, 29.36, 147.73, 8.02, 17.45, 9.92, 43.72, 2.83, 0.64, 0.5, 0.12, 0.92, 0.45, 27.95 and 1.04 mg/kg (dry soil) for V, Cr, Mn, Co, Ni, Cu, Zn, As, Mo, Ag, Cd, Sn, Sb, Pb and U respectively. Most school playgrounds with elevated heavy metals concentrations were found in Manfuah, Al Shifa, Al Yamamah, Sultanah, An Namuthajiyah, Al-Wurud and Al-Shimaisi residential districts due to their proximity to main traffic roads, industrial areas and high density residential areas. On the other hand schools playgrounds with lower heavy metals levels were found in An Nuzhah, Al-Aqiq and Al-Jazirah districts which may be attributed to less traffic emissions, low residential density, and their distant location from the industrial areas. The measured concentrations levels of the heavy metals in the soil, except for Pb, were below the allowable concentration limits. The Pb concentration exceeded these limits in Manfuhah school playground. The enrichment coefficient values for V, Cr, Mn, Co, Ni and Cu were less than unity at 0.32, 0.47, 0.25, 0.51, 0.44 and 0.36 respectively, suggesting that the origin of these elements is mostly the local soil. The enrichment coefficient values for Zn and Pb were more than unity at 1.66 and 8.47, respectively, suggesting that these elements are anthropogenic in origin, for example, from the traffic emissions.

In Salbukh, meanwhile, the lead concentrations were 1.63, 1.52, 1.20 and 21.31 ?g/g in the rats' liver, kidney, and intestine, and in H. diminuta, respectively. In addition, in industrial area II, compared with the liver, kidney and intestine of their host, the bioconcentration factors of lead were found to be, respectively, 15.6, 16 and 21.9 times higher in H. diminuta, and were 7.5, 8, and 10.2 times higher in the same organs compared to H. diminuta in Salbukh. The present study, therefore, proved that H. diminuta could be used as a bioindicator for heavy metal contamination in the industrial areas of the city of Riyadh. PMID:25183950

    Full Text Available To obtain a more recent and comprehensive insight into the prevalence of glomerular diseases in our patient population, medical records of 200 patients with biopsy proven glomerulonephritis (GN, between January 1994 and June 1999, at the King Khalid University Hospital, Riyadh, Saudi Arabia were analyzed. Primary glomerular disease was found to be the most prevalent, accounting for 63.5% of all glomerular diseases. Among primary glomerular diseases, focal and segmental glomerulosclerosis (FSGS was the most common histological lesion (34.6% and was associated with a high prevalence of hypertension (86.4%, nephrotic syndrome (68.18%, hematuria (63.6% and renal functional impairment (27.3%. Mesangioproliferative GN was the second most common lesion (25.1% followed by mesangiocapillary GN (15.7%, IgA nephropathy (10.2%, and minimal change disease (8.5%. Amongst secondary glomerular diseases, lupus nephritis was the most prevalent (24.5%. In conclusion, primary glomerular diseases constituted the commonest group encountered and the prevalence of FSGS was quite high with male sex and young adults predominating. FSGS was also associated with a high prevalence of end-stage renal disease. Further collaborative studies are necessary to explore the predisposing factors and associations of glomerular disease, especially FSGS.

    Full Text Available The survey was conducted to explore use, knowledge and attitudes toward complementary and alternative medicine (CAM among pharmacy students at the college of pharmacy, King Saud University. A total of 133 fourth- and fifth-year pharmacy students completed a questionnaire designed to explore their use, knowledge and attitudes toward CAM therapies at the college of pharmacy, King Saud University. Study lasted for 3 months from 1 st of October until 31 st of December in 2007. Nutrition and herbal medicine therapies were the most known therapies by 65% and 53% of the students, respectively. Knowledge about CAM therapies among the students was limited. Thirty-nine percent of the students reported use of some form of CAM at least once in their lifetime. CAM was used for acute, chronic and mild illness as well as nutrition. Herbal medicine, nutrition, massage, relaxation exercises, yoga and mega-dose vitamin were the most CAM used. Lectures were the chief CAM information source. More than one half of the respondents (53-70% believed that five of the 15 CAM modalities were useful, namely massage, herbal medicine, nutrition, yoga and relaxation exercises. Respondents had a positive attitude toward statements that favoured CAM. Most students strongly agreed or agreed that most CAM therapies were efficacious, whereas 52.6% of the respondents did believe that CAM therapies can be harmful to public health. The study showed that the students had positive attitude toward CAM and exhibited relatively high level of self-reported use of CAM therapies. Overall, students? knowledge of CAM is limited. The students perceived interest in learning and training in CAM. A separate course in CAM including its various components is needed. Also, availability of a reliable CAM information sources will aid the students to increase their knowledge of CAM.

    Siham, Al-Kadeeb A.

    In this study, soil samples for isolation of heavy metal resistance fungi were collected from different distance of Electric Meter manufactory in Second Industrial City, Riyadh, Saudi Arabia. Soil samples were analyzed chemically for heavy metal concentrations, total soluble salts and pH and mechanically for composition of soils. Saturation percent were determined also. Eighteen fungal isolates were grown in 10 mM concentration of either lead or copper ions. Aspergillus was predominant and represented by 6 species. Fusarium was represented by 4 species. Mucor was represented by 3 species. Penicillium was represented by 2 species. While Alternaria, Cephaliophora, Eurotium were represented by one species each. The intraspecific variability in growth response to Pb2+ and Cu2+ on agar and liquid culture was studied among isolated fungi. The growth rate of some fungi isolated on solid media was less sensitive to addition of lead or copper than biomass production in liquid culture.

    Full Text Available Abstract Background This study was conducted to examine the perception and views of medical students regarding the extent of alcohol and substance abuse in the community and the possible predisposing factors for this problem. Methods It is a cross-sectional study involving samples from two medical colleges in Riyadh, Saudi Arabia. The students who decided to participate in the study without the offer of any incentives filled an anonymous, self administered questionnaire which had been designed to meet the purpose of the study. Results Two hundred and fifteen out of three hundred and thirty students (65% response rate participated in this study. About 75% of them believe that alcohol and substance abuse is a common problem in the community. Students' views also correspond with the reported view that the problem is mainly present in young adult males. Married males and senior students perceived the problem as more serious than their other colleagues. Students perceived that alcohol was the most commonly abused drug in the community, followed by amphetamines, heroin, cannabis and cocaine. They believe that influence of friends, life stressors, tobacco smoking and curiosity are the most important predisposing factors for abuse of alcohol and other substances. According to the students' perception, the main beneficial effect of alcohol and substance abuse was stress alleviation. About 3% of the students have also indicated that they may use alcohol or some other substance in the future. Conclusion Despite scarce information on the subject and a strong religious belief in Saudi Arabia against the use of alcohol and other addictive substances, a significant majority of the medical students in Riyadh, the capital of Saudi Arabia, perceived that alcohol and substance abuse is a common problem in the community. Some students appear to perceive the seriousness of the problem less than others. Efforts are needed to educate young men and women at an early stage of their academic life, as a medical student about the existence of this problem in the community, its consequences and predisposing factors. Teaching teenagers and young adults about stress coping strategies may be of special importance in reducing the risk of alcohol and substance abuse.

It is assumed that factors such as dress codes, restrictions on going outdoors, and conservative norms are the main reasons for women’s low physical activity. Our aim was to explore the different parameters related to physical activity, including self-efficacy, as well as the perceived barriers to and benefits of physical activity in young Saudi females.Patients and methods: Ninety-four first-year female Saudi university students in Riyadh, Kingdom of Saudi Arabia, participated in the present study in 2014. The students were from eight bachelor’s programs in health and well-being, and each completed a questionnaire with questions divided into five parts as follows: 1 socioeconomic status, 2 physical activity, 3 self-efficacy 4 social factors, and 5 barriers and facilitators related to physical activity.Results: The students exercised at home and alone, and there was low self-efficacy for physical activity (mean score =42±14. Among social factors, attending university was the only factor that hindered physical activity (32%. Physical activity was positively perceived overall (mean score =131±10. Students showed awareness of the benefits of physical activity for health and well-being. The most important barrier was the lack of designated areas available for physical activity. Students disagreed that family or the Islamic community were barriers to physical activity.Conclusion: The lack of facilities and lack of encouragement from the university, but not a lack of knowledge (a high level of knowledge is to be expected given their health and well-being studies backgrounds and/or restrictions from families and society, seem to hinder female students’ physical activity, at least young Saudi students.Keywords: physical activity, Kingdom of Saudi Arabia, females, barriers and facilitators, self-efficacy

  15. Tuning of Lee Path Loss Model based on recent RF measurements in 400 MHZ conducted in Riyadh City, Saudi Arabia

    International Nuclear Information System (INIS)

    In mobile radio systems, path loss models are necessary for proper planning, interference estimations, frequently assignments and cell parameters which are basic for network planning process as well as Location Based Services (LBS) techniques that are not based on GPS system. Empirical models are the most adjustable models that can be suited to different types of environments. In this paper, the Lee path loss model has been tuned using Least Square (LS) algorithm to fit measured data for TETRA system operating 400 MHz in Riyadh urban and suburbs. Consequently, Lee model's parameter (L0, y) are obtained for the targeted areas. The performance of the tuned Lee model is then compared to the three most widely used empirical path loss models: Hat, ITU-R and Cost 231 Walfisch-Ikegami non line-of-sight (CWI-NLOS) path loss models. The performance criterion selected for the comparison of various empirical path loss models are the Root Mean Square Error (RMSE) and goodness of fit (R2). The RMSE and R2between the actual and predicted data are calculated for various path loss models. It turned that the tuned Lee model outperforms the other empirical models. (author)

    Objectives: To evaluate the gender-specific difference in the prevalence of depression and anxiety and the help-seeking behavior among gastroenterology outpatients. Methods: A cross-sectional study was carried out in gastroenterology clinics in 4 hospitals in Riyadh, Saudi Arabia between February and September 2013. A self-administrated questionnaire was developed and administered to patients. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder (GAD-7) questionnaires were used to identify depression and anxiety. Results: A total of 438 patients completed the study questionnaire; 135 (31%) females, and 303 (69%) males. Compared with males, females had more depression symptoms (44% versus 32%, p=0.012), anxiety symptoms (34% versus 24%, p=0.036), anxiety-associated difficulty (65% versus 52%, p=0.012), but similar suicidal thoughts (14% versus 11%, p=0.347). Females had similar gastrointestinal complaints but longer duration of symptoms. In both females and males, the most common first interventions were using medications (63% versus 69%), and undergoing endoscopy (19% versus 15%), while very few patients initially used herbs or Islamic incantation “Roquia” (7% versus 8%). Compared with males, females were more likely to subsequently seek help at private clinics (23% versus 14%, p=0.014), or with a Quran therapist (11% versus 5%, p=0.012). Conclusion: There are clear gender-specific differences in depression and anxiety symptoms and associated perceived difficulty, but modest differences in help-seeking behavior. Female patients at the gastroenterology clinic may deserve more psychological attention to diagnose depression and anxiety and to alleviate their impact. PMID:24983282

    Full Text Available E-learning that integrates digital knowledge content, network and information technology has become an emerging learning method. As the e-learning platform approach is becoming an important tool to allow the flexibility and quality requested by such a kind of learning process. There is a new kind of problem faced by organizations consisting in the selection of the most suitable e-learning platform. This paper proposes evaluation model for E-Learning platform in Riyadh City universities (RCU with Applied Geographic Information System (GIS. The E-Learning platform solution selection is a multiple criteria decision-making problem that needs to be addressed objectively taking into consideration the relative weights of the criteria for any organization. We formulate the quoted multi criteria problem as a decision hierarchy to be solved using GIS. AGIS-based evaluation index system and web-based evaluating platform were established. In this paper we will show the general evaluation strategy and some obtained results using our model to evaluate some existing commercial platforms.The results of evaluation model are outlined as follows: Total weights of the proposed framework in management feature is 20.25/25, in collaborative feature is 9.2/10, in adaption learning path is 6.8/10 and in interactive learning object is 5/5. The total weights of all features are 41.25/50. In this study an evaluation model was applied on Riyadh City universities like KSU, IMAMU, NAUSS, YU and FU. Then, the results were compared with each other. The total weighs of KSU was 41. While the total weights of FU, IMAMU, YU and NAUSS was 40, 37, 36 and 32, respectively. Evaluation process shows that the proposed framework satisfied the objectives with applied GIS.

    Translation of research evidence into public health programs is lagging in Eastern Mediterranean Region. Graduate level public health curriculum at King Saud University (KSU), College of Medicine, Riyadh, is designed to equip students to integrate best available evidence in public health decision making. The objectives of study were to explore students' opinion about the evidence based public health (EBPH) courses and to survey the knowledge, opinion, and attitude of the students towards EBPH and perceived barriers for implementation of EBPH in decision making in public health. EBPH courses are designed based on a sequential framework. A survey was conducted at the completion of EBPH courses. Forty-five graduate students were invited to complete a validated self-administered questionnaire. It included questions about demography, opinion, and attitude towards EBPH and perceived barriers towards implementation of EBPH in the work environment. The response rate was 73%. Mean age of students was 30.1 (SD 2.3) years, and 51% were males. More than 80% had sound knowledge and could appreciate the importance of EBPH. The main perceived barriers to incorporate EBPH in decision making were lack of system of communication between researchers and policy makers and scarcity of research publications related to the public health problems.

  13. Characteristics and sources of organic matter in Desert Sand Samples from Riyadh and Al-Qasim Areas of Saudi Arabia: Preliminary Results

    International Nuclear Information System (INIS)

    Sand samples from Riyadh and Al-Qasim areas were collected, extracted with a mixture of dichloromethane and methanol (3:1, v: v), and analyzed by gas chromatography-mass spectrometry (GC-MS) in order to characterize the contents and sources of their organic compounds. The major components of the total extracts were the straight chain aliphatic compounds from vegetation waxes, fossil fuel combustion and anthropogenic and agricultural activities. The results showed that the anthropogenic inputs had a significant contribution to the organic content of sands near populated areas. The urban component consisted mainly of n-alkanes, n-alkonic acids, n-alkyl amides, hopane and sterane biomarkers and pesticide residues. Organic inputs from natural sources include n-alkanes, n-alkonic acids, n-alkanols, methyl alkanoates, sterols and n-alkanones. (author)

  17. High prevalence of osteoporosis in Saudi men

    International Nuclear Information System (INIS)

    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)

The General Administration of Mental Health and Social Services of the Ministry of Health over the past 4 years has sought to streamline the delivery of mental health care services to health consumers in Saudi Arabia. Objective: We overview here the outcome of a survey that assessed the Saudi MHS and suggest strategic steps for its further improvement. Method: The World Health Organization Assessment Instrument for Mental Health Systems was used systematically to collect information on the Saudi MHS in 2009–2010, 4 years after a baseline assessment. Results: Several mental health care milestones, especially provision of inpatient mental health services supported by a ratified Mental Health Act, were achieved during this period. However, community mental health care services are needed to match international trends evident in developed countries. Similarly, a larger well-trained mental health workforce is needed at all levels to meet the ever-increasing demand of Saudi society. Conclusion: This updated MHS information, discussed in light of international data, will help guide further development of the MHS in Saudi Arabia in the future, and other countries in the Eastern Mediterranean region may also benefit from Saudi experience.

    Full Text Available Mostafa A Abolfotouh,1,2 Mohammed H Al-Assiri,1 Manar Al-Omani,2 Alwaleed Al Johar,3 Abdulaziz Al Hakbani,3 Ahmed S Alaskar1,2 1King Abdullah International Medical Research Center, 2King Saud bin-Abdulaziz University for Health Sciences, 3College of Medicine, King Saud University, Riyadh, Saudi Arabia Introduction: In Saudi Arabia, voluntary donors are the only source of blood donation. 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 knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals' places of work to reduce their time costs of donating is a necessity.

    The aim of this study was to evaluate the ability of admissions criteria at King Saud University (KSU), Riyadh, Saudi Arabia, to predict students' early academic performance at three health science colleges (medicine, dentistry, and pharmacy). A retrospective cohort study was conducted with data from the records of students enrolled in the three colleges from the 2008-09 to 2010-11 academic years. The admissions criteria-high school grade average (HSGA), aptitude test (APT) score, and achievement test (ACT) score-were the independent variables. The dependent variable was the average of students' first- and second-year grade point average (GPA). The results showed that the ACT was a better predictor of the students' early academic performance than the HSGA (?=0.368, ?=0.254, respectively). No significant relationship was found between the APT and students' early academic performance (?=-0.019, p>0.01). The ACT was most predictive for pharmacy students (?=0.405), followed by dental students (? =0.392) and medical students (?=0.195). Overall, the current admissions criteria explained only 25.5% of the variance in the students' early academic performance. While the ACT and HSGA were found to be predictive of students' early academic performance in health colleges at KSU, the APT was not a strong predictor. Since the combined current admissions criteria for the health science colleges at KSU were weak predictors of the variance in early academic performance, it may be necessary to consider noncognitive evaluation methods during the admission process.

    Full Text Available Higher education institutions are major drivers of change in achieving environmental sustainability both within college campuses and beyond campuses in communities at large. However, achieving campus sustainability is not possible without the involvement of students as one of the major stakeholders of a university. Based on survey of 152 students of the College of Architecture and Planning, University of Dammam, Saudi Arabia, this study explores students’ assessment of campus sustainability components: curriculum and research; campus operations; and community involvement. The results show that even though the students indicate a great deal of awareness and concern about campus environmental sustainability, they lack interest and willingness to participate in initiatives towards achieving sustainability. Apart from some sustainable landscaping and waste recycling practices, there are few sustainability initiatives in transportation and energy and water conservation on the campus. Offered courses and student projects have also been reported to have modest focus on sustainability. The article concludes by highlighting the roles of incorporating sustainability into campus operations, and training university students in promoting environmental sustainability in Saudi Arabia and the Middle East.

  6. Hysterectomy for benign conditions in a university hospital in Saudi Arabia

    International Nuclear Information System (INIS)

    Hysterectomy is a common surgical procedure among women with a lifetime prevalence of 10%. The indications and complications of this procedure have not been previously reported from a teaching institution in Saudi Arabia. We examined the indications for hysterectomy and the surgical morbidity for women undergoing hysterectomy at a university hospital in Saudi Arabia. We reviewed the records of women who underwent hysterectomies for benign gynecological conditions between January 1990 and December 2002, at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, comparing patient characteristics, indications for hysterectomy and the rate of complications in women undergoing abdominal hysterectomy (AH) versus vaginal hysterectomy (VH). Of 251 women 199 (79%) underwent AH and 52 (21%) underwent VH. An estimated blood loss of >=500 mL occurred in 104 patients (52.3%) in the AH group and in 20 patients (38.5%) in the VH group (difference not statistically significant). The most common indications for hysterectomy were uterine fibroids (n=107, 41.6%) and dysfunctional uterine bleeding (n=68, 27.1%). The most common indication for VH was uterine prolapsed (n=45, 86.5%). The overall complication rates were 33.5%, 15.4% and 30.4% in women who underwent the AH group and in 51 patients in the VH group (20.3%). Postoperative infection occurred in 42/199 (21.6%) in the AH group and 5/52 (9.6%) in the VH group (difference not statistically significant). We describe a large series of hysterectomies, which provides information for surgeons on the expected of complications following hysterectomy for benign conditions. We describe a large series of hysterectomies, which provides information for surgeons on the expected rate of complications following hysterectomy for benign conditions. We found that the rate of complications was not significantly higher than other centers internationally. (author)

    This paper investigates the effectiveness of the Building Energy Management System (BMS) installed in the typical buildings in the main campus of King Abdulaziz University, Jeddah, in Saudi Arabia. As the domestic electricity and hence the oil consumption in Saudi Arabia is increasing at a very alarming rate compared to the other countries in the world, it is of paramount importance to resort to urgent measures in various industrial, commercial and residential sectors in the country to implement energy conservation measures. The major electrical load in the buildings in the University corresponds to air-handling units and lighting. If the Hajj period, during which millions of pilgrims visit Holy Makah, coincides with the summer, the electricity demand in the country further increases. Considering these issues, the university has taken initiatives to minimize energy consumption in the campuses through the various energy conservation measures. Towards this end, BMS is installed in a few of the typical classrooms and office buildings utilizing the existing campus Ethernet TCP/IP. The data analysis is performed over the period from April to September as it is the peak load period due to summer season. The effectiveness of the BMS in the minimization of the energy consumption in these buildings is established by comparing the results of data analysis with BMS against those before the installation of BMS over the peak period. The investigations reveal that appreciable saving in energy consumption can be achieved with the installation of BMS, the magnitude being dependent upon factors such as building characteristics, type of building, its utilization and period of use.

    The Kingdom of Saudi Arabia is one of the main oil producing countries, yet the latest five year development plan calls for energy conservation. Due to the expansion of the Saudi economy, which is reflected by the challenging and ambitious development in various sectors, such as housing, health, industry, agriculture, education etc., the consumption of electric energy experienced a sharp increase during the last twenty years. In 1983 the Ministry of Education implemented various strategies to conserve energy consumption by school buildings. In the 1990s more attention is geared towards improving the U-value of the external envelope through the use of hollow blocks and thermal insulation. This study is an attempt to investigate the effectiveness of the use of thermal insulation and hollow blocks in reducing energy consumption. This is conducted by the analysis of actual electric energy consumption of some selected examples of school buildings in Riyadh. Also the study will investigate other energy conservation strategies which might yield additional energy savings. This will be carried out using analysis of the Riyadh climate. (author)

    2014-11-01

    Conclusions: This is probably the first reported outbreak of multidrug/carbapenem-resistant Klebsiella infection involving the OXA-48 gene from Saudi Arabia. Although the presence of ESBLs such as OXA, CTX-M, TEM, and SHV are predictable reasons for resistance, variations in the Omp-36 gene might also have precipitated this phenomenon. Disruption of the Omp-36 sequence by large insertional elements, the insertion of two amino acids in a very crucial part of this protein, and the presence of a premature stop codon in one isolate might have rendered this protein incomplete and non-functional. The study also demonstrated that more than one type of clone was responsible for this reported apparent outbreak and that ST29, a clone not reported from this region before, was the major clone responsible.

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

National data on the assessment of technical skills during surgical training are lacking. We conducted this study to document the assessment tools for technical skills currently used in different surgical specialties, their relationship with remediation, the recommended tools from the program directors’ perspective, and program directors’ attitudes toward the available objective tools to assess technical skills.Methods: This study was a cross-sectional survey of surgical program directors (PDs. The survey was initially developed using a focus group and was then sent to 116 PDs. The survey contains demographic information about the program, the objective assessment tools used, and the reason for not using assessment tools. The last section discusses the recommended tools to be used from the PDs’ perspective and the PDs’ attitude and motivation to apply these tools in each program. The associations between the responses to the assessment questions and remediation were statistically evaluated.Results: Seventy-one (61% participants responded. Of the respondents, 59% mentioned using only nonstandardized, subjective, direct observation for technical skills assessment. Sixty percent use only summative evaluation, whereas 15% perform only formative evaluations of their residents, and the remaining 22% conduct both summative and formative evaluations of their residents’ technical skills. Operative portfolios are kept by 53% of programs. The percentage of programs with mechanisms for remediation is 29% (19 of 65.Conclusion: The survey showed that surgical training programs use different tools to assess surgical skills competency. Having a clear remediation mechanism was highly associated with reporting remediation, which reflects the capability to detect struggling residents. Surgical training leadership should invest more in standardizing the assessment of surgical skills.Keywords: objective assessment, program directors, surgical skills, surgical residency

    Full Text Available In this prospective study we wanted to determine whether perceived stress over time among students in the Preparatory Year of King Saud University (KSU predisposes them to cardiometabolic abnormalities. A total of 110 apparently healthy Saudi students (35 men and 75 women enrolled during the 2010?2011 academic year were included. Perceived stress was determined at baseline and 1 year later. Anthropometrics were obtained and morning fasting serum glucose, lipid profile and cortisol were measured at both times. Perceived stress was noted among 48.2% of subjects at baseline and was not significantly different after follow-up, with 45.4% scoring high. In men, the prevalence of perceived stress was 48.6% at baseline (13 out of 35 and 37.1% at follow-up (13 out of 35, while in women it was 48% at baseline and 49.3% at follow-up. Interestingly, significant improvements in the blood pressure and lipid profiles, with the exception of HDL-cholesterol, were observed in both men and women, while fasting glucose also improved in women. Serum cortisol was inversely associated to fasting glucose, and total- and LDL-cholesterol (p-values 0.007, 0.04 and 0.04, respectively. These data are opposite to findings in students entering Western universities, in whom increasing stress and a deteriorating cardiometabolic profile have been repeatedly noted. Perceived stress and morning cortisol levels among students of the Preparatory Year in KSU remained constant for both genders over time, yet an improved cardiometabolic profile was observed, suggesting good adaptation among our pre-college students in their first year of university life.

    Full Text Available Background: Hirsutism among women of fertile age is commonly seen in clinical practice, but the pattern of the disease in Saudi Arabs has not been studied. The aim of the study was to determine the clinical, biochemical and etiologic features of hirsutism in Saudi females. Methods: 101 Saudi Arab women presenting with hirsutism at King Khalid University Hospital, Riyadh, Saudi Arabia, from 1 January 2000 to 31 December 2005 were prospectively assessed using the recently approved diagnostic guidelines for hyperandrogenic women with hirsutism. Results: Polycystic ovary syndrome (PCOS was the cause of hirsutism in 83 patients (82% followed by id-iopathic hirsutism (IH in 11 patients (11 %. Others causes of hirsutism included late onset congenital adrenal hyperplasia in 4 patients (4%, microprolactinoma in 2 (2% and Cushing?s syndrome in 1 (1% patient. Age at presentation of PCOS was 24.5±6.6 years (mean±SD and 51 % of the subjects were obese. Furthermore, 74 (89% of patients with PCOS had an oligo/anovulatory cycle while the remaining 9 patients (11 % maintained normal regular menstrual cycle. Luteinizing hormone and total testosterone were significantly higher in patients with PCOS than in those with IH (P< .05. Conclusions: The present data show PCOS to be the commonest cause of hirsutism in our clinical practice and PCOS is prominent amongst young obese females. However, further studies on a larger scale are needed to verify our findings.

Methods: This is a retrospective descriptive epidemiological study of all Saudi female breast cancer cases from 2001 to 2008. The statistical analyses were conducted using descriptive statistics, a linear regression model, and analysis of variance with the Statistical Package for the Social Sciences version 20 (IBM Corporation, Armonk, NY, USA. Results: A total of 6,922 female breast cancer cases were recorded in the Saudi Cancer Registry from 2001 to 2008. The highest overall percentages (38.6% and 31.2% of female breast cancer cases were documented in women who were 30–44 and 45–59 years of age, respectively. The eastern region of Saudi Arabia had the highest overall ASIR, at 26.6 per 100,000 women, followed by Riyadh at 20.5 and Makkah at 19.4. Jazan, Baha, and Asir had the lowest average ASIRs, at 4.8, 6.1, and 7.3 per 100,000 women, respectively. The region of Jouf (24.2%; CIR 11.2, ASIR 17.2 had the highest changes in CIR and ASIR from 2001 to 2008. While Qassim, Jazan and Tabuk recorded down-trending rates with negative values. Conclusion: There was a significant increase in the CIRs and ASIRs for female breast cancer between 2001 and 2008. The majority of breast cancer cases occurred among younger women. The region of Jouf had the greatest significant differences of CIR and ASIR during 2001 to 2008. Jazan, Baha, and Najran had the lowest average CIRs and ASIRs of female breast cancer, whereas the linear trend upward is a concern in certain regions, such as the eastern region, Makkah, and Riyadh. However, further analytical epidemiological research is needed to identify the potential risk factors involved in the increase in the prevalence of breast cancer among Saudi women.

    Full Text Available Aim of the Study: The complex hospital environment requires special attention to ensure a healthy indoor air quality (IAQ to protect patients and healthcare workers against hospital-acquired infections and occupational diseases. Poor hospital IAQ may cause outbreaks of building-related illness such as headaches, fatigue, eye, and skin irritations, and other symptoms. The general objective for this study was to assess IAQ inside a large University hospital at Al-Khobar City in the Eastern Province of Saudi Arabia. Materials and Methods: Different locations representing areas where most activities and tasks are performed were selected as sampling points for air pollutants in the selected hospital. In addition, several factors were studied to determine those that were most likely to affect the IAQ levels. The temperature and relative percent humidity of different air pollutants were measured simultaneously at each location. Results: The outdoor levels of all air pollutant levels, except volatile organic compounds (VOCs, were higher than the indoor levels which meant that the IAQ inside healthcare facilities (HCFs were greatly affected by outdoor sources, particularly traffic. The highest levels of total suspended particulates (TSPs and those less than 10 microns (PM 10 inside the selected hospital were found at locations that are characterized with m4ore human activity. Conclusions:Levels of particulate matter (both PM 10 and TSP were higher than the Air Quality Guidelines (AQGs. The highest concentrations of the fungal species recorded were Cladosporium and Penicillium. Education of occupants of HCF on IAQ is critical. They must be informed about the sources and effects of contaminants and the proper operation of the ventilation system.

However, current national estimates on fruit and vegetable consumption in the Kingdom of Saudi Arabia (KSA are nonexistent. We conducted a large household survey to inform the Saudi Ministry of Health (MOH on a major modifiable risk factor: daily consumption of fruits and vegetables. Methods: The Saudi Health Interview Survey is a national multistage survey of individuals aged 15 years or older. It includes questions on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. We used a backward elimination multivariate logistic regression model to measure association between the Centers for Disease Control and Prevention (CDC-recommended daily consumption of fruits and vegetables and different factors. Results: Between April and June 2013, a total of 10,735 participants completed the survey. Overall, 2.6% of Saudis aged 15 years or older met the CDC guidelines for daily consumption of fruits and vegetables. The likelihood of meeting the CDC guidelines increased with age; among women; among persons who graduated from elementary or high school or had a higher education; among residents of Makkah, Al Sharqia, Ha’il, or Jizan; among those who consumed at least two servings of meat or chicken per day; among those who visited a health care facility for a routine medical exam within the last 3 years; and among those who have been diagnosed with hypertension. Conclusion: We have showed that KSA is in dire need of improving the diet of its population. Our findings call for urgent research to understand the reasons for low fruit and vegetable consumption, focusing on price or preference in order to develop and implement culturally and country-relevant solutions to increase the consumption of fruits and vegetables.

  10. Outcome of stroke in Saudi children

    International Nuclear Information System (INIS)

    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. However, 20 (87%) of them had significant delays in their developmental milestones. The toll of stroke in Saudi children is demanding, with most children demonstrating persistent neurologic or cognitive deficits. Primary prevention for recurrences is feasible through informed genetic counseling. (author)

    Full Text Available Background: The high prevalence of physical inactivity in Saudi Arabia is a growing challenge to public health. This study aimed to examine the prevalence of physical activity (PA and associated factors among female university students. Methods: This cross-sectional study involved 663 randomly selected female university students who completed the Arab Teens Life Style questionnaire. Data included measurements of anthropometric, socioeconomic and environmental factors, as well as self-reported PA. Ordinal regression was used to identify associated factors with low, moderate and high PA levels. Results: The mean age of participants was 20.4 years (SD 1.5. Mean BMI of the students in relation to PA were 23.0, 22.9, 22.1 for high, moderate and low levels of activity, respectively. The analysis revealed significantly higher PA levels among married students, those with high educated mothers, and those who lived far from parks, and lower activity levels among underweight students. Conclusions: This study raises four important determinants for female university students’ PA levels. These factors could be of great importance in the endeavor to prevent the health-threatening increase in physical inactivity patterns and thus non-communicable diseases and obesity where the focus should be on the specific situation and needs of women in Saudi Arabia.

  15. Cephalometric norms of Saudi boys

    International Nuclear Information System (INIS)

    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)

    Full Text Available Objectives: To assess health care services provided to type 1 and type 2 diabetic patients and diabetes health care expenditure in the Kingdom of Saudi Arabia (KSA. Methods: This study was part of a nationwide, household, population based cross-sectional survey conducted at the University Diabetes Center, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia between January 2007 and December 2009 covering 13 administrative regions of the Kingdom. Using patients’ interview questionnaires, health care services data were collected by trained staff. Results: A total of 5,983 diabetic patients were chosen to assess health care services and expenditure. Approximately 92.2% of health services were governmental and the remaining 7.8% were in private services. The mean annual number of visits to physicians was 6.5±3.9 and laboratories was 5.1±3.9. Diabetic patients required one admission every 3 years with a mean admission duration of 13.3±28.3 days. General practitioners managed 85.9% of diabetic cases alone, or shared with internists and/or endocrinologists. Health care expenditure was governmental in 90% of cases, while it was personal in 7.7% or based on insurance payment in 2.3%. Conclusion: Health services and its expenditure provided to diabetic citizens in Saudi Arabia are mainly governmental. Empowerment of the role of both the private sector and health insurance system is badly needed, aside from implementing proper management guidelines to deliver good services at different levels.

    International Nuclear Information System (INIS)

    This prospective study was conducted to demonstrate the role of bone mineral density (BMD) and bone scan in the management of adult Saudi female patients with established diagnosis of osteomalacia. Bone scan using Tc99m methylene diphosphate (MDP) and BMD of the lumbar spine and femoral neck using dual x-ray absorptiometry (DXA) were performed at the time of diagnosis 6 months and one year after therapy in 96 Saudi female patients attending the metabolic bone disease clinic at King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia, between January 1997 through to June 1999, aged between 20 and 73 years (mean 42 years). Alkaline phosphates, calcium and inorganic phosphorus were measured for all patients before and after treatment. 25 Hydroxy vitamin D was only measured with the first BMD measurements. A bone profile showed typical biochemical abnormalities of osteomalacia.The bone scan showed features of superscan in all patients and pseudofractures in 43 patients. BMD measures were compared with that of normal Saudi subjects matched for age and sex. The BMD was low at diagnosis and showed significant improvement after therapy. The improvement of bone density in response to therapy was more evident in lumbar spine than in femoral neck bone.Our results showed that BMD in adult Saudi female patients with osteomalacia was markedly affected probably due to specific constitutional and environmental factors ( inadeqate exercise, lack of sun exposure and lack of intake of milk and dairy products). In addition, lumbar BMD and serum calcium appeared to be better markers to monitor therapy.Bone scan helped in demonstrating disease activity, the presence of pseudofractures. (author)

  19. Life styles related to coronary artery disease in Saudi Males older than 12 years of age

    International Nuclear Information System (INIS)

    The present study highlighted life styles related to coronary artery disease risk factors among patients attending a primary care clinic at King Khalid University Hospital, in Riyadh, Saudi Arabia. We conducted a cross-sectional study at a primary care clinic at King Khalid University Hospital, Riyadh, Saudi Arabia, during the period from 18/4/2006 to 13/6/2006. All adult male patients older than 12 years of age who attended one consultant primary care clinic were included in the study. All patients were interviewed by one consultant in family medicine during the study period. The patients were asked about dietary habits, physical activity and type of exercise, and smoking habits. Weight and height was taken for all patients by the nurse in the clinic and body mass index (BMI) were calculated for all patients. The total number of participants was 246 patients. The data were analyzed using the Statistical Package of Social Science (SPSS) version 11.5. A p value of less than 0.05 was considered statistically significant. Of the 246 male adult patients, 45.4% always consumed vegetables and fruits in their diet, 21.5% exercised on a daily basis, 51.2% exercised sometimes and 26% did not exercise at all. The type of exercise practiced by active participants was walking (76.5%) and sports (22.9%). Sports included football, basketball, swimming and other sports club activity. Only 20.7% of the participants had an ideal body weight (BMI=30). 8.9% of the participants were current smokers. Overweight and obesity is a common health problem among male adult patients attending a primary care setting. Improved dietary habits (consumption of vegetables and fruits and minimization of fat and suits) encouraging exercise and walking and helping current smokers to quit smoking are essential steps towards improving life styles in the community. It is an important health plan priority to concentrate on improving life styles in the Saudi community, to prevent cardiovascular risk factors and to reduce the prevalence of the coronary artery disease in the Kingdom of Saudi Arabia. Further, national community-based studies are recommended to evaluate life style factors related to coronary artery disease among both males and females at different age groups in Saudi Arabia.

  1. Infection control practice in private dental laboratories in Riyadh

    International Nuclear Information System (INIS)

    In view of the risk of infection of dental health care workers and patients, interruption of possible chains of infection is to be demanded. The objective of this study was to assess infection control practice in private dental laboratories in Riyadh City, Kingdom of Saudi Arabia. The study was conducted on thirty-two private dental laboratories in Riyadh City regarding infection control practiced by these laboratories. The instrument of the study consisted of ten open-ended questions that were asked from the laboratories directors. A large percentage of the surveyed laboratories (87.5 %) did not implement any infection control protocol during their practice. The mean number of impressions received per week was 16. Most of the surveyed laboratories (90.6 %) had no way of communication with the clinics regarding the disinfection procedures. The results indicated that 62.5 % of the laboratories reported that they were aware that they may get infection from non-disinfected items. Only a small percentage (6.2%) of the laboratories added disinfecting agent to pumice slurry. Wearing laboratory coats was reported by 75% of the laboratory workers. The use of gloves during work was reported by 59.3% of the laboratories while 56.2% reported the use protective eyewear. Only 21.8% of the laboratories use face masks during work. Construction of infection control manuals that contain updated and recommended guidelines to ensure aseptic practice in private dental laboratories is highly recommended. Also, a way of communication between dentists and dental technicians regarding disinfection of laboratory items should be strongly encouraged. (author)

    International Nuclear Information System (INIS)

    The widespread use of mobile phones has been increased over the past decade; they are now an essential part of business, commerce and society. The use of mobile phones can cause health problems. Therefore, the aim of the present study is to investigate the association of using mobile phones with fatigue, headache, dizziness, tension and sleep disturbance in the Saudi population and provide health and social awareness in using these devices. This study was conducted in the Department of Physiology, College of Medicine, King Saudi University, Riyadh, Kingdom of Saudi Arabia during the year 2002 to 2003. In the present study, a total of 437 subjects (55.1% male and 39.9% female) were invited, they have and had been using mobile phones. A questionnaire was distributed regarding detailed history and association of mobile phones with health hazards. The results of the present study showed an association between the use of mobile phones and health hazards. The overall mean percentage for these clinical findings in all groups were headache (21.6%), sleep disturbance (4.%), tension (3.9%), fatigue (3%) and dizziness (2.4%). Based on the results of the present study, we conclude that the use of mobile phones is a risk factor for health hazards and suggest that long term or excessive use of mobile phones should be avoided by health promotion activities such as group discussions, public presentations and through electronic and print media sources.

    Cardiovascular complications in sickle cell disease (SCD) have been well documented but cardiac involvement in Saudi patients with SCD is not known. We sought to identify cardiac abnormalities by electrocardiography in adolescent and adult Saudi patients with stable SCD. Sixty-five consecutive patients with SCD followed at King Khalid University Hospital, Riyadh, were prospectively studied from January 2005 to December 2005. All patients underwent echocardiographic examination to determine chamber dimensions, left ventricular function, valvular anomalies and pulmonary artery pressure. Data were compared to normal age and gender-matched controls. Hematological data were also collected from the patients and correlated with the echocardiographic results. Twenty-eight males and 37 females were evaluated. The mean age of the group was 24.5+-9.2 range (14-44) years. The most common abnormality found was pulmonary hypertension (PH) present in 25 (38%) patients. The majority of these patients had mild PH and only 6 (9%) patients had pulmonary artery systolic pressure (PASP) more than 40 mm Hg. Older age, lower level of fetal hemoglobin and high serum ferritin were associated with increased PASP. Other abnormalities present included dilated left atrium in 17 (26%) patients, dilated right atrium 13 (20%), dilated left ventricle 10(15%), valvular anomalies 21 (32%) and reduced ejection fraction in 4 (6%) patients. Cardiac abnormalities are found in a significant proportion of Saudi patients with SCD. Pulmonary hypertension is the most common finding while other abnormalities are less frequent. (author)

Knowledge of breast self examination (BSE) was high 82% (95% CI, 79.2%-84.4%) knew about BSE, 61% (95% CI confidence intervals [CI], 79.2%-84.4%) knew about BSE , while 61% [95%CI, 57.9%-64.5%] knew about mammography but only 41.2% [95% CI, 37.9%-44.5%] had performed BSE and 18.2% (95% CI, 15.5%-20.8%)had had mammography screening Knowledge of breast cancer, risk factors and protective factors for breast cancer was moderate. There was a statistically significant association between demographic characteristics (marital status, educational status and family history of breast cancer) and knowledge and practice of BSE and mammography. Though it has limitations, this study revealed an imbalance between the knowledge and practice of BSE among women. It also showed that there is only that there is only moderate knowledge of risks and protective factors for breast cancer and that knowledge and practice of BSE and mammography vary according to marital and educational status. Hence, frequent community based awareness programs are needed so that all women can know and practice BSE, which in turn helps to prevent breast cancer. (author)

    Full Text Available Abeer A Alharbi,1 Hamza Mohammad Abdulghani2 1Department of Family and Community Medicine, 2Department of Medical Education, College of Medicine, King Saud University, Riyadh, Saudi Arabia Introduction: Postpartum depression (PPD is one of the major psychological disorders worldwide that affects both mother and child. 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

  15. Resting heart rate and its relationship with general and abdominal obesity in young male Saudi university students

    International Nuclear Information System (INIS)

    An elevated resting heart rate (Rhr) has been linked with adverse cardiovascular outcomes. Obese people have altered autonomic balance that could lead to elevated Rhr and altered responses to postural changes. As no comparative data are available on Rhr in young normal weight (NW) and obese (OB) adults in Saudi Arabia, the present study was aimed at finding out the effect of adiposity on RHR and RHR response to change in posture. Methods: Second-year male students (n=231; age:19-20 years), were recruited from the Dammam University, Dammam, Saudi Arabia, during the period September 2008 to October 2009. Anthropometric measures were obtained and indices of obesity (body mass index [EMI], waist circumference [WC], waist-to-hip ratio [WHR], waist-to-stature ratio [WSR]) were calculated. RHR in standing and supine positions were obtained from radial pulse. Pearson's correlation (r) between obesity indices and RHR as well as the differences between RHR in NW and OB groups were calculated. Results: General obesity (BMI greater or equal to 25.0 kg/m1 was found in 45.5% students. Central obesity (WC>85 cm or WSR>50.0) was found in 36.8% students. RHR was significantly correlated with BMI, WC and WSR (r=O.305, 0.300, 0.299 respectively, p< O.01) . Subjects above the obesity indices cut-off points had significantly higher values of RHR in both standing and supine positions compared to NW individuals (p<0.05). There was a greater reduction in RHR on changing the posture to supine state in OB group. Conclusion: A significantly higher RHR and a greater change in RHR on changing the posture point towards an altered autonomic balance in OB group of young adolescent males. This underscores the need to implement health education program to combat obesity at school and college levels. (author)

    International Nuclear Information System (INIS)

    The present study highlighted life styles related to coronary artery disease risk factors among patients attending a primary care clinic at King Khalid University Hospital, in Riyadh, Saudi Arabia Methods: We conducted a cross-sectional study at a primary care clinic at King Khalid University Hospital, Riyadh, Saudi Arabia, during the period from 18/4/2006 to 13/6/2006. All adult male patients older than 12 years of age who attended one consultant primary care clinic were included in the study. All patients were interviewed by one consultant in family medicine during the study period. The patients were asked about dietary habits, physical activity and type of exercise, and smoking habits. Weight and height was taken for all patients by the nurse in the clinic and body mass index (BMI) was calculated for all patients. The total numbers of participants were 246 patients. The data were analyzed using the Statistical Package of Social Science (SPSS) version 11.5. A p value of less than 0.05 was considered statistically significant. Results: Of the 246 male adult patients, 45.4% always consumed vegetables and fruits in their diet, 21.5% exercised on a daily bases, 51.2% exercised sometimes, and 26% did not exercise at all. The type of exercise practiced by active participants was walking (76.5%) and sports (22.9%). Sports included football, basketball, swimming, and other sport club activity. Only 20.7% of the participants had an ideal body weight (BMI<25), 37.4% were overweight (BMI 25 to <30), while 37.7% of the participants were obese (BMI ? 30). 8.9% of the participants were current smokers. Conclusion and recommendation: Overweight and obesity is a common health problem among male adult patients attending a primary care setting. Improved dietary habits (consumption of vegetables and fruits, and minimization of fat and sweets), encouraging exercise and walking, and helping current smokers to quit smoking are essential steps towards improving life styles in the community. It is an important health plan priority to concentrate on improving lifestyles in the Saudi community, to prevent cardiovascular risk factors and to reduce the prevalence of coronary artery disease in The Kingdom of Saudi Arabia. Further, national community-based studies are recommended to evaluate lifestyle factors related to coronary artery disease among both males and females at different age groups in Saudi Arabia.

    International Nuclear Information System (INIS)

    To determine the mean eruption time of permanent first molars, central and lateral incisors and to compare the relationship of mean eruption time with body mass index (BMI) in Saudi female primary school children from Riyadh, Saudi Arabia. The mean age of children was 89.3 (SD 9.6) months ranging from 71 months to 109 months. The maxillary right first molar had the lowest mean eruption time of 77.4 (SD 3.9) months and the maxillary right lateral incisor was the last tooth to erupt with eruption time of 98.4 (SD 6.5) months. Furthermore, the mandibular incisors erupted significantly earlier than maxillary incisors. By the age of 100 months, 97% of the girls had all their first permanent molars erupted. There was no significant correlation observed between eruption times with BMI of the studied teeth except the maxillary right lateral incisor. However, an inverse relationship may exist between the eruption times and BMI. The Saudi female primary school children showed later eruption time of permanent first molars, central and lateral incisors when compared with the reported results of other national studies. Key words: Eruption time, permanent teeth, Saudi Arabia, female children. (author)

    BACKGROUND AND OBJECTIVES: Riyadh and central province falls in a moderate prevalent zone of hemoglobinopathies in Saudi Arabia. However, it has been observed that the physicians working in Saudi Arabia invariably advise all cases of anemia for hemoglobin electrophoresis (HE). The present work was carried out to study the yield of the HE in Riyadh and the investigative practices of the physicians advising HE. SETTINGS AND DESIGN: The study was carried out in the hospitals of King Saud University from 2009 to 2011 in order to assess the yield of HE in referred cases of clinical anemia. MATERIALS AND METHODS: A total of 1073 cases divided in two groups of males and females had undergone complete blood count and red blood cell morphology. Cellulose acetate HE was performed and all the positive results were reconfirmed on the high performance liquid chromatography (HPLC). The results were analyzed for the type of hemoglobinopathies. For statistical analysis Statistical Package for Social Sciences 15 version (SPSS Inc., Chicago, IL, USA) was used. RESULTS: A total of 405 males and 668 females blood samples were included in the present study. 116 (28.5%) males and 167 (25%) females showed an abnormal pattern on HE. The incidence of beta thalassemia trait was higher in females while sickle cell trait was predominantly seen in males. Red cell indices were reduced considerably in thalassemias, but were unaffected in sickle cell disorders, except those which had concurrent alpha trait. The total yield of HE was 26.6% which was much less than expected. CONCLUSION: The physicians are advised to rule out iron deficiency and other common causes of anemia before investigating the cases for hemoglobinopathies, which employs time consuming and expensive tests of HE and HPLC.

    International Nuclear Information System (INIS)

    A pilot study to estimate the prevalence of osteopenia and osteoporosis in postmenopausal Saudi woman. Lumbarspine bone density was measured in 830 postmenopausal Saudi women 50-80 years of age (average 59 years), using dual x-ray absorptiometry (DXA) at the King Khalid University Hospital,Riyadh,Kingdom of Saudi Arabia between 1989 and 1999. The result of the bone mineral density (BMD) in gram/cm2 were compared to the peak bone density (PBD) in healthy young women (T-score). Based on the definition of World Health Organization (WHO),the T-score value was considerd for analysis. Accordingly 248 (29.9%) subjects showed normal results,mean MBD of 1.117+-0.13 and T-score of-0.66SD; whlie 254(30.6%) subjects showed osteopenia ,mean BMD of 0.983+-0.11and T-score of -2.4 SD and 328( 39.5%) subjects showed osteoporosis,mean BMD of 0.767+-0.11and T-score of -3.4SD. when 830 subjects were analyzed by decades ,there were 42.3% normal , 33.4% osteopenia and 24.3% osteoporosis in age 50-59 years; 11% normal, 27% with osteopenia and 62% with osteoporosis in age 60-69 years while in older age 70-79 years only 4.6 had normal BMD, 21.5% had osteopenia and73.8% had osteoporosis. Osteopenia and osteoporosis are common among postmenopausal Saudi women and should be considerd as a matter of public health .Bone densitometry should be used to acess the severity of bone loss, identify those who need therapy and for follow up and early diagnosis of those with osteopenia in order to institute proper therapy and avoid future osteoporosis.

  3. Hematologic risk factors for stroke in Saudi children

    International Nuclear Information System (INIS)

    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. The study strongly highlights the importance of prothrombotic disorders and the severe phenotype of SCD as risk factors for stroke in Saudi children. (author)

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

    Objectives: To determine the prevalence and predictors of self-medication with analgesics among senior medical students and interns in King Abdulaziz University (KAU), Jeddah, Saudi Arabia. Methods: A cross-sectional study was conducted among 504 participants in 2013. A multistage stratified random sampling was used. A confidential, anonymous & self-administered questionnaire was used to collect personal & socio-demographic data. Data about self-medication and self-medication with analgesics during the preceding 6 months were also inquired. Both descriptive and analytical statistics were done by SPSS version 18 & Epi-Info. Results: During the 6 months preceding the study, 75.2% and 55.4% of participants used self -medication & analgesic self-medication, respectively. The first predictor of utilization of analgesic self-medication was living with family (aOR; 1.96, 95% CI: 1.22-3.14), followed by age >21 years & non- professional jobs of fathers. Conclusion: Alarming high rates of self medication and self-medication with analgesics were observed among medical students and interns. Self-medication needs improvement through educational, regulatory and managerial strategies. PMID:25878607

    Full Text Available Background and Aim: Medication Errors can result in drug-related problems (DRPs. Insight into the frequency, type, and severity of DRPs could help reduce their incidence. The aim of the present study was to estimate the prevalence of admissions as a result of DRPs at the Emergency Department (ED of a university hospital in the Kingdom of Saudi Arabia. Materials and Methods: Files of suspected cases of DRPs reporting to ED in the year 2012 were scrutinized. Suspicion arose from the hospital record system based on Diagnosis Code Numbers (ICD-9-CM, Professional 2010 and from triggers, such as some drugs, laboratory tests, and signs and symptoms pointing to DRPs. Results: Of 5574 admissions, 253 (4.5% were DRPs and were categorized as: Overdose toxicity and side effects of drugs 50 (19.8%, drug-interactions 29 (11.5%, accidental and suicidal drug ingestions 26 (10.3%, drug abuse 18 (7.1%, drug allergy 10 (4%, super-infections 8 (3.2%, and noncompliance to treatment 112 (44.3%. About 70% of DRPs were preventable; 67 (26.5% required hospital admission for 7-102 days and 10 (4% died. Conclusions: Noncompliance to treatment, overdose toxicity, drug interactions, and drug abuse are important causes of hospital admissions as a result of DRPs. Awareness of prescribers to the problem and their education would help to prevent them and improve patient care.

  15. Association of physicians' knowledge and behavior with prostate cancer counseling and screening in Saudi Arabia

    International Nuclear Information System (INIS)

    To investigate the knowledge, attitudes and practices of primary care physicians towards prostate cancer counseling and screening. This cross sectional study was conducted in May 2009 to October 2009 through a survey questionnaire, which was distributed to all licensed primary care physicians in Riyadh, Saudi Arabia. The study took place in the Princes Al-Johara Al-Ibrahim Center for Cancer Research, King Saud University, Saudi Arabia. Data was obtained from 204 primary care physicians using self-reports of prostate cancer screening practices, knowledge, attitudes towards prostate cancer screening, and continuous medical education preferences. Respondents' characteristics were also collected. Approximately 54.7% of the respondents were practicing counseling and referring prostate cancer patients. The mean correct knowledge score was 54.3%, their attitude was not strong; the only statement that approximately 70% of physicians agreed upon was about the value of screening, however, the reliability and evidence to support digital rectal examination and prostatic specific antigen were in question. Our primary care physicians had self-confidence in suspecting and referring high-risk patients for screening, but not for management and treatment. Knowledge and attitude were found to be the most significant predictors that determine physicians' self practice. Physicians' practice towards a screening procedures or early detection of diseases should rely on a good background of information, which in turn enhances their self-efficacy and develops a good and positive attitude towards their practice skills (Author).

    Full Text Available Objectives: Sleep deprivation is common among medical residents of all specialties. This study aimed to determine the prevalence of sleep deprivation and depressive symptoms among medical residents in King Fahd University Hospital (KFUH in Al Khobar, Saudi Arabia. Furthermore, the association between sleep deprivation, sleepiness and depressive symptoms was examined. Methods: This cross-sectional study took place between February and April 2012 and involved 171 KFUH medical residents of different specialties. Data were collected using a specifically designed questionnaire eliciting demographic information, working hours and number of hours of sleep. In addition, validated Arabic versions of the Epworth Sleepiness Scale and the Beck Depression Inventory-2 (BDI-2 were used. Results: The prevalence of acute sleep deprivation and chronic sleep deprivation among residents in KFUH was 85.9% and 63.2%, respectively. The prevalence of overall sleepiness was 52%; 43.3% reported being excessively sleepy in certain situations while 8.8% reported being excessively sleepy regardless of the situation. Based on the BDI-2, the prevalence of mild, moderate and severe depressive symptoms was 43.3%, 15.2% and 4.7%, respectively. Significant associations were found between sleep deprivation and depressive symptoms; depressive symptoms and sleepiness, and depressive symptoms and being a female resident. Conclusion: The vast majority of medical residents had acute sleep deprivation, with more than half suffering from chronic sleep deprivation. The number of hours and quality of sleep among the residents were strongly associated with depressive symptoms. New regulations are recommended regarding the number of working hours and night duties for medical residents. Further studies should assess these new regulations on a regular basis.

Investments made in adolescent health and health services protect the improvements witnessed in child health. Though Saudi Arabia has a large adolescent population, adolescent health-care only began to emerge in recent years, yet widespread uptake has been very limited. Health-care providers are key in addressing and providing the necessary health-care services for adolescents, and so this study was conducted with the aim of identifying opportunities for the advancement of knowledge transfer for adolescent health services in Saudi Arabia. Methods: This Web-based, cross-sectional study was carried out at four hospitals in Saudi Arabia. Physicians and nurses were invited to participate in an online survey addressing their contact with adolescent patients, and training, knowledge, and attitudes towards adolescent health-care. Results: A total of 232 professionals participated. The majority (82.3% reported sometimes or always coming into contact with adolescent patients. Less than half (44%, however, had received any sort of training on adolescent health during their undergraduate or postgraduate education, and only 53.9% reported having adequate knowledge about the health-care needs of adolescents. Nurses perceived themselves as having more knowledge in the health-care needs of adolescents and reported feeling more comfortable in communicating with adolescents as compared with physicians. The majority of participants were interested in gaining further skills and knowledge in adolescent health-care and agreed or strongly agreed that adolescents have specific health-care needs that are different than children or adults (82.3% and 84.0%, respectively. With respect to health services, the majority (85.8% believed that adolescents should be hospitalized in adolescent-specific wards. Only 26.7% of health-care providers believed that patients should be transferred from child to adult health-care services at 12–13 years of age, as is currently practiced in the country. Conclusion: A gap exists between the training, knowledge and skills of health-care providers, and the needs to address health-care issues of adolescents in Saudi Arabia. This coupled with the fact that health-care providers are interested in gaining more knowledge and skills and are supportive of changes in the health-care system provides an opportunity for building local capacity and instituting medical and nursing education and health-care reform that can better serve the needs of the country's young population.

  7. Seismic noise study for a new seismic station at King Fahd University of Petroleum and Minerals in Saudi Arabia

    Kaka, S. I.

    2012-04-01

    We have carried out a seismic noise study in order to understand the noise level at three selected locations at King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, Saudi Arabia. The main purpose is to select a suitable site with low seismic noise and good signal-to-noise ratio for our new broadband seismic station. There are several factors involved in the selection of a site location for a new station. Most importantly, we need to strike a balance between a logistically convenient site versus a technically suitable site. As a starting point, we selected six potential sites due to accessibility and proximity to the seismic processing center laboratory in the Department of Earth Sciences (ESD) at KFUPM. We then eliminated two sites that are relatively close to possible low-frequency noise sources. We have considered many possible noise sources which include: vehicle traffic / heavy machinery, the direct path of air flowing from air conditioning vent, tall trees / power poles and metal doorways. One more site was eliminated because the site was located in the open where it experiences maximum wind speed which is considered a major source of noise. All three potential sites are situated within the Dammam Dome where both lower middle and upper Rus Formations are exposed. The upper Rus is mainly made up of fine grained chalky limestone and the lower Rus is made up of alternation of marls and thin dolomitic limestone. The area is not known for any major faults and considered very low seismicity and hence the identification of seismoteconic features is not required. Before conducting the noise study, we calibrated and tested the seismic recording system, which was recently acquired by the ESD at KFUPM. The system includes a seismic recorder and a sensor with a GPS device. We deployed the system in order to measure the low-frequency background noise. Knowing the low frequency noise will help in predicting the high-frequency noise. The recording systems were deployed for twenty eight days (based on the memory available with the recorder) continuously collecting data at all three potential sites. This continuous data collection was done as part of a larger study where microtremor measurements were made to better understand and characterize the origin of various near-surface noises over a non-producing reservoir in Dhahran, Saudi Arabia (Papoola and Kaka, 2011). The new station at KFUPM will be equipped with a 3-component 120s to 50Hz Trillium120 broad band seismometer, Taurus 24-bit data acquisition system along with a large LCD to display the waveform data in real-time. The KFUPM community will have an opportunity to observe daily seismic activity in real-time and to monitor/record both regional and teleseismic events. Moreover, students will gain the opportunity to identify P, S, Love, and Rayleigh waves and learn how to locate an earthquake. The station will also play an important role in providing a source of information about seismic activity for the general public. The new station is expected to be operational in a few months time.

  9. Breast cancer correlates in a cohort of breast screening program participants in Riyadh, KSA

    International Nuclear Information System (INIS)

    Background: Breast cancer is the first cancer among females in the Kingdom of Saudi Arabia, accounting for 27.4% of all newly diagnosed female cancers in 2010. There are several risk factors affecting the incidence of breast cancer where some factors influence the risk more than the others. Aim: We aimed to identify the different risk factors related to breast cancer among females participating in the breast-screening program in Riyadh, KSA. Methods: Based on data from phase-I of the breast-screening program, a case-control study was conducted on women living in Riyadh, KSA. A sample of 349 women (58 cases and 290 controls) was recruited to examine the different breast cancer correlates. Multivariate regression model was built to investigate the most important risk factors. Results: The mean age of cases was 48.5 ± 7.1 years. Age at marriage, number of pregnancy, age at menopause, oral contraceptive pills, breast feeding and family history of breast cancer in first-degree relative were identified as the most important correlates among the studied cohort. Conclusions: The findings of the current work suggested that age at marriage, age at menopause ?50 years, and 1st degree family history of breast cancer were risk factors for breast cancer, while, age at menopause<50 years, number of pregnancies and practicing breast feeding were protective factors against breast cancer. There was no effect of body mass index or physical inactivity. Further studies are needed to explore the hereditary, familial and genetic background risk factors in Saudi population.

Some of the encountered morbidity demonstrated seasonal variation. Case referrals were about 6 %, more in the non-infectious conditions, with a deficient feedback system. Conclusion : Quality improvement of the medical records and the establishment of a proper referral system are necessary. Health education on preventable morbid conditions should be organized and implemented.

  11. Perinatal stroke in Saudi children: clinical features and risk factors

    International Nuclear Information System (INIS)

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

  12. Stroke due to mitochondrial disorders in Saudi children

    International Nuclear Information System (INIS)

    Objective was to report on the clinical and biochemical features of patients who presented with stroke due to mitochondrial disorders amongst a prospective and retrospective cohort of Saudi children. Children, who presented with stroke 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 periods July 1992 to February2001 (retrospective study)and February 2001 to March 2003 (prospective study). Open muscle biopsies were obtained from patients suspected to have mitochondrial disorders, and examined using conventional histological and histochemical techniques. Biochemical, molecular pathological investigations, or both, of muscle could be arranged for only some of the patients. Mitochondrial disorders were the underlying risk factor for stroke in 4 (3.8%) of 104 children (aged one month to 12 years). Three patients (one male and 2 females) had Leigh syndromes (LS) and one had mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS). At the time of stroke, the 3 children with LS were 11 months, 15 months, and 7 years old. They presented with psychomotor regression and seizures. Muscle histology and histochemistry showed mild non-specific changes but no ragged red fibers. Biochemical analysis of muscle (in one patient) revealed deficiency of pyruvate dehydrogenase complex. Analysis of mitochondrial DNA (mtDNA), [the other 2 patients] was negative for the 2 point mutations (T-G and T-C) at nucleotide position 8993, and for two T-C point mutations (at position 8851 and 9176 of the ATPase 6 gene) that have been described in patients with LS. The girl with MELAS syndrome presented with a stroke-like episode at the age of 29 months and had focal brain lesions in the media aspect of the left occipital and temporal lobes, and in the posteromedial aspect of the left thalamus, which resolved within 7 weeks. She had raised cerebrospinal fluid lactate but no ragged red fibres on muscle histochemistry. Biochemical assay of muscle homogenate showed reduction in respiratory chain complexes I, III and IV. Mutation screening of mtDNA at nucleotides 3243 (tRNA) and 8344 (tRNA) was negative. Mitochondrial disorders constitute a risk factor for stroke in Saudi children. However, demanding and highly specialized investigations are needed to confirm the diagnosis. These are better performed at supraregional centers where facilities for clinical biochemical and molecular work-up are available. (author)

    Full Text Available Due to the increasing of complexity in software projects, group work is becoming more important in order to ensure quality software products can be delivered on time. Thus, in universities, group work is seen as a good preparation for students to enter industry because by working in group, it can reduce the individual workload, improve the ability to manage a project and enhance the problem solving skills. However, due to lack of programming skills especially in Javaprogramming language, most of the students’ software project cannot be delivered successfully. To solve this problem, systematic group formation is one of the initial factors that should be considered to ensure that every group consists of quality individuals who are good in programming. This paper presents a method for group formation using genetic algorithm, where the members for each group will begenerated based on the students’ programming skill.

Methods: In a retrospective, noncomparative interventional case series, the medical records of patients who underwent PKP from January 2000 to December 2008 and had a minimum follow-up of 6 months were reviewed. All corneas were obtained from eye banks in the US. Indications, complications, and outcomes of surgery were recorded. This study was approved by the institutional review board. Results: Eighty-five consecutive eyes were included in this study. There were 52 (61.2% males and 33 (38.8% females. The median age was 35.0 years (range 3–85 years, and the median follow-up period was 24 months (range 6–108 months. The indications for PKP were keratoconus, bullous keratopathy, corneal scars, corneal dystrophy, and corneal regraft. The overall graft survival time was 88.9 months ± 4.9 months (mean ± standard error of mean, 95% confidence interval [CI] 79.4 months -98.4 months while the 3-year and 5-year cumulative survival rates were 90.7% and 84.3%, respectively. Surgical indication (P = 0.038, immune rejection (P < 0.001, preoperative corneal vascularization (P = 0.022, and perioperative high intraocular pressure (P = 0.032 were associated significantly with corneal graft failure in univariate analysis. Multivariate analysis reduced these significant associations to rejection (P < 0.001 and vascularization (P = 0.009. Relative risk for failure in rejected cornea was 16.22 (95% CI 4.99–52.69 and in vascularized cornea was 3.89 (95% CI 1.36–11.09. At last visit following PKP, 34 (40% eyes had best spectacle-corrected visual acuity of 20/40 or better, and 51 (60.0% eyes had 20/80 or better. Best spectacle-corrected visual acuity was worse than 20/400 in 15 (17.6% eyes. Conclusion: The overall corneal graft survival in a private setting in Saudi Arabia can be excellent. Thorough preoperative evaluation and comprehensive postoperative management are crucial for successful corneal transplantation. A larger multicenter study is recommended to portray the outcome of private corneal transplantation in Saudi Arabia in general.

    In 2011-2012, sixty nine samples were collected from alfalfa plants showing viral infection symptoms in Riyadh region. Mechanical inoculation with sap prepared from two collected samples out of twenty five possitive for Alfalfa mosaic virus (AMV) by ELISA were produced systemic mosaic on Vigna unguiculata and Nicotiana tabacum, local lesion on Chenopodium amaranticolor and C. quinoa. Vicia faba indicator plants that induce mosaic and mottle with AMV-Sagir isolate and no infection with AMV-Wadi aldawasser isolate. Approximately 700-bp was formed by RT-PCR using AMV coat protein specific primer. Samples from infected alfalfa gave positive results, while healthy plant gave negative result using dot blot hybridization assay. The nucleotide sequences of the Saudi isolates were compared with corresponding viral nucleotide sequences reported in GenBank. The obtained results showed that the AMV from Australia, Brazil, Puglia and China had the highest similarity with AMV-Sajer isolate. While, the AMV from Spain and New Zealaland had the lowest similarity with AMV-Sajer and Wadi aldawasser isolates. The data obtained in this study has been deposited in the GenBank under the accession numbers KC434083 and KC434084 for AMV-Sajer and AMV- Wadialdawasser respectively. This is the first report regarding the gnetic make up of AMV in Saudi Arabia. PMID:25288969

    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(OH)D) 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(OH)D 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. PMID:26861386

    Objectives: To estimate age at menarche and to assess trends in menarcheal age among Saudi women. Methods: A prospective longitudinal study was conducted among healthy prepubertal female school children and adolescents from September 2006 to July 2012 in Riyadh, Kingdom of Saudi Arabia. Study participants were invited from diverse socioeconomic backgrounds. Tanner stage, height, weight, body mass index, and socioeconomic parameters including parent’s level of education were collected. Age at menarche was compared with maternal age at menarche. Results: The study included 265 girls and mothers. Mean±standard deviation (SD) age at menarche for girls was 13.08 ± 1.1 years, and their distribution category across the ?10 years was 4 (1.5%), 11-14 years was 239 (90.2%), and ?15 years was 22 (8.3%) girls. Anthropometric measurements, mother’s level of education, and family income were not statistically significant determining factors associated with age at menarche. Mean ± SD age at menarche for mothers was 13.67 ± 1.4 years, and their distribution category across the ?10 years was 7 (2.6%), 11-14 years was 172 (64.9%), and ?15 years was 86 (32.5%). Girls attained menarche at younger age compared with their mothers (p<0.0001). A downward secular trend in age of menarche was observed (Cuzick test for trend = 0.049). Conclusion: Saudi girls attain menarcheal age earlier than their mothers, reflecting a downward secular trend in menarcheal age. PMID:26593166

  1. Infectious and inflammatory disorders of the circulatory system as risk factors for stroke in Saudi children

    International Nuclear Information System (INIS)

    Objective was to report on the role of infectious and inflammatory disorders as risk factors for stroke in a prospective and retrospective cohort of Saudi children. Children, who presented with stroke, 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 periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Investigations for suspected cases included haemostatic assays, microbiological and serological tests. Neuroimaging included cranial CT, MRI magnetic resonance angiography (MRA), magnetic resonance venography (MRV) and single photon emission computed tomography (SPECT) brain scan. Of the 104 Saudi children with stroke, seen during the combined study periods of 10 years and 7 months, infectious and inflammatory disorders of the circulatory systems were identified risk factors in 18 (17.3%). Five children had stroke following acute bacterial meningitis at ages ranging between 5-21 months. The causative organism was identified in 3 of them and consisted of Haemophilus influenza (in a 5-months-old girl), Streptococcus pneumonia (in a 21-months-old girl complicated by subdural empyema and sinovenous thrombosis), and Staphylococcus aureus in a 6-months-old boy who had an underlying chronic granulomatous disease. Unspecified meningitis/meningoencephalitis affected 4 patients, whereas 3 children had an underlying congenital infection as a cause for their stroke. Two of the latter 3 children were diagnosed to have congenital toxoplasmosis, and the third had congenital rubella syndrome. Two girls had stroke following septicemia at ages of one and 2 months. Neurobrucellosis caused stroke in 2 boys at the ages of 4 1/2 and 4 years. In both patients, neuroimaging revealed lacunar and other infects involving mainly the deep cerebral nuclei, secondary to occlusion of small penetrating end arteries. Two patients presented with cerebrovascular disease following systemic lupus erythematosus. These were a 12-year-old girl and a 5-year-old boy. Several of the infectious diseases that caused stroke in this cohort of Saudi children are children are potentially preventable through childhood immunization programs or other maternity health programs. In particular, immunogenic conjugate vaccines against 3 most common organisms causing acute bacterial meningitis (Haemophilus influenzae type b, Neissaria meningitides and defined serotypes of Streptococcus pneumoniae) are needed to protect the young (<2 years) who are mostly affected.

    This study provides a descriptive epidemiological data of thyroid cancer cases diagnosed from 2001 to 2008 among Saudi women, including the frequency and percentage of cases, the crude incidence rate (CIR) and the age-standardised incidence rate (ASIR) stratified by the region and year of diagnosis. This is a retrospective descriptive epidemiological analysis of all Saudi thyroid cancer cases recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008. The statistical analyses were applied using descriptive statistics with the Statistical Package for the Social Sciences version 20.0. A total of 2,930 cases were recorded in the SCR between January 2001 and December 2008. The region of Riyadh in Saudi Arabia had the highest overall ASIR at 9.43 per 100,000 women, followed by Tabuk at 7.11 and eastern region at 6.5, while Jazan and Jouf had the lowest average ASIRs at 1.97 and at 2.72, respectively. The region of Qassim recorded the greatest changes of ASIR at 5.5 per 100,000 women from 2001 to 2008. There was a slight increase in the CIRs and ASIRs for thyroid cancer in Saudi Arabia between 2001 and 2008. Riyadh, Tabuk and eastern region were the highest overall ASIR in Saudi Arabia. While, Jazan and Hail had the lowest rates. Finally, the region of Qassim had the highest changes in CIR and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of thyroid cancer disease among Saudi women. PMID:24859807

  10. Indoor radon levels in Riyadh city dwellings

    International Nuclear Information System (INIS)

    Full text: Building materials used for construction of houses represent a major source of indoor radon. In this investigation, indoor radon concentrations are found to vary substantially among the different building materials, ventilation, cooling and heating systems used. This paper presents the effects of these factors on the radon concentration in Riyadh city dwellings. The measurements were obtained by using a passive integrating ionization system with an E-Perm Electret ion chamber. The study covered more than 700 houses and apartments, which were selected to cover the most common type of houses. The concentration range was found to be 1.02 to 196 Bq.m-3, with an average value of 17.5 ± 3 Bq.m-3. The results show that the radon concentration is higher in houses where the white bricks, no ventilation systems, plastic paint and Freon air conditioners are used, but relatively lower in houses where the red bricks, window ventilation, and water air conditioner is used.

  11. Cardiac diseases as a risk factor for stroke in Saudi children

    International Nuclear Information System (INIS)

    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. The sixth patient was an 8 1/2-year-old girl who had hemiparesis and complex partial seizure in association with restrictive cardiomyopathy. Serial echocardiograms depicted resolution of the cardiac abnormalities within 5 years and subsequent normal findings. Cardiac diseases, as, a group constitute a significant risk factors for stroke in Saudi children. Early diagnosis of these diseases is important to prevent further recurrences of stroke, and because some of them are potentially curable. (author)

    Objectives: To determine the prevalence of self-medication and assess the knowledge, attitudes, and perception of consumers toward self-medication. Methods: This cross-sectional survey was conducted over 4 weeks in May 2011 in Riyadh city, Kingdom of Saudi Arabia. Community pharmacies within 5 areas of the city (North, South, West, East, and Middle) were randomly selected for the study. All consumers were approached to participate in the study, with the exception of those buying cosmetic and medicinal equipments. A validated self-administered questionnaire was used to collect the data. Results: A total of 538 out of 707 consumers attending community pharmacies in Riyadh city, agreed to participate in the study. Most responders were male (73%), 23-33 years old (35%), and college graduates (42%). A total of 285 medications were bought without a prescription. Of these, 149 (49%) medications should be dispensed by prescription only, and 155 (51%) were over the counter medications. The most common prescription medications dispensed without prescriptions were antibiotics (22%) and analgesics/antipyretics (19%). The most common reasons for buying medications without a prescription were that the symptoms were too minor to visit a doctor (54%), time saving (40%), and minor illnesses for which the participants knew the required treatment (40%). Overall, most participants had poor knowledge, and negative perceptions regarding self-medication. More than 68% of participants did not know whether the medicine they bought is a prescription-only or over the counter medication. Conclusion: Irresponsible self-medication is common in Saudi Arabia. Future studies should focus on improving the consumers’ awareness of self-medication and the proper use of medications. PMID:25737176

  13. Adjustment factors for the ASHRAE clear-sky model based on solar-radiation measurements in Riyadh

    International Nuclear Information System (INIS)

    The solar-radiation variation over horizontal surfaces calculated by the ASHRAE clear-sky model is compared with measurements for Riyadh, Saudi Arabia. Both model results and measurements are averaged on an hourly basis for all days in each month of the year to get a monthly-averaged hourly variation of the solar flux. The measured data are further averaged over the years 1996-2000. The ASHRAE model implemented utilizes the standard values of the coefficients proposed in the original model. Calculations are also made with a different set of coefficients proposed in the literature. The results show that the ASHRAE model calculations generally over-predict the measured data particularly for the months of October ? May. A daily total solar-flux is obtained by integrating the hourly distribution. Based on the daily total flux, a factor PHI (<1) is obtained for every month to adjust the calculated clear-sky flux in order to account for the effects of local weather-conditions. When the ASHRAE model calculations are multiplied by this factor, the results agree very well with the measured monthly-averaged hourly variation of the solar flux. It is recommended that these adjustment factors be employed when the ASHRAE clear-sky model is used for solar radiation calculations in Riyadh and localities of similar environmental conditions. Instantaneous, daily and yearly solar-radiation on various surfaces, such as building walls and flat-plate solar collectors, can then be conveniently calculated using the adjusted model for different orientations and inclination angles. The model also allows the beam, diffuse and ground-reflected solar-radiation components to be determined separately. Sample results characterizing the solar radiation in Riyadh are presented by using the 'adjusted' ASHRAE model

Although plant leaves of Indigofera oblongifolia have been used for the treatment of malaria in Saudi Arabian society, there is no laboratory-based evidence for the effectiveness and safety of the plant. This study therefore was designed to investigate the antimalarial and spleen protective activity of I. oblongifolia leaf extract (IOLE in mice. Three doses (100, 200 and 300 mg/kg of IOLE were used to treat mice infected with Plasmodium chabaudi-parasitized erythrocytes. The suppressive effect produced by the 100 mg/kg dose on parasitemia was highly significant compared to the infected nontreated group. This dose was also able to repair the change in the thickness of the mice spleen and significantly lower the number of apoptotic cells in the spleen. Moreover, I. oblongifolia also altered gene expression in the infected spleen. On day 7 postinfection, the mRNA expression of six genes – with immune response functions – was upregulated by more than twofold, while that of 24 other genes was downregulated. Among the differentially up- and downregulated genes under the effect of IOLE, we quantified the expression of Ccl8, Saa3, Cd209a, and Cd209b mRNAs. The expression data, determined by microarrays, were largely consistent with the expression analyses we performed with several arbitrarily selected genes using quantitative polymerase chain reaction (PCR. Based on our results, I. oblongifolia exhibits antimalarial activity and could protect the spleen from P. chabaudi-induced injury.

    International Nuclear Information System (INIS)

    Studies on fragile X syndrome are scarce in Saudi Arabia and othercountries of the Arabian Peninsula. The few studies previously done haveeither been in the form of case reports or those performed oninstitutionalized mentally retarded patients. The aim of this study was todetermine the prevalence of fragile X syndrome among cases with mentalretardation who have been referred to the pediatric neurology clinics of KingKhalid University Hospital (KKUH) in Riyadh. Cytogenetic studies wereperformed in 94 cases that were referred to the pediatric neurology clinicsof KKUH because of mental retardation and/or delayed milestones ofdevelopment, from July 1995 to December 1997. Six male probands (6.4%) showedthe classic fragile X chromosome and another six (including a four year oldgirl) were detected, following extension of the cytogenetic studies to all 32first-degree relatives. Affection of more than one sibling was ascertained infour families. One family had four brothers with fragile X syndrome, whereasanother formed part of a large kindred with twelve males and five females whowere mentally retarded. A clinical, physical and psychological screeningchecklist was applied to the eleven affected males. Large testicular size,long face and short attention span were the most frequent features and eachwas detected in nine patients (82%). Pes planus and history of delayed speechwere found in eight patients (73%).

  16. Attitude, belief and knowledge about blood donation and transfusion in saudi population

    International Nuclear Information System (INIS)

    Blood donation and transfusion are remarkably safe medical procedures. However, attitudes, beliefs and level of knowledge associated with blood donation and transfusion may affect such procedures. Therefore, the aim of this study was to determine the attitude, belief and knowledge about blood donation and transfusion in Saudi Population. The present study was conducted in the Department of Physiology, College of Medicine, King Saud University Hospitals, Riyadh, Saudi Arabia. A well structured Arabic questionnaire was used to asses the attitude, belief and knowledge regarding blood donation and transfusion. The sample consisted of 335 male (55%) and 274 female (45%); the majority of the sample (65.84%) were non-donors. These non-donors (78.98%) were between the ages of 15-30 years. The 88.5% of the people who participated in the study believed that blood donation was not harmful, 20% of them stated that they would refuse blood transfusion even if they were in need because of the risk of acquiring infectious disease. 84.5% preferred direct donation, (49%) of the sample stated that they would accept blood donation only from relatives, 55.1% believed that blood transfusion was safe. However, 11.6% claimed to have acquired infectious disease after blood transfusion, 58% female in addition to 11.34% male preferred to receive blood from female donor and 69.5% did not know if the blood banks were in need of blood or not and 17.4% believed that all surgical procedures require blood transfusion. Different fears, mistrust in hospital and lack of information may serve as an important issue to be addressed when developing donors recruitment programs or campaigns to clear misconceptions about blood donation. In addition, public should know that numerous screening measures are implemented to ensure that blood donation is safe for the donor and that transfusion of the donated blood is safe for the recipient.

  17. Dyspnea, pulmonary function and exercise capacity in adult Saudi patients with sickle cell disease

    International Nuclear Information System (INIS)

    Objective was to examine pulmonary function, dyspnea, and exercise capacity in adult Saudi patients with sickle cell disease (SCD) patients. The patients were recruited from the hematology clinic at King Khalid University Hospital in Riyadh from January to December 2005. The study involved 39 patients with stable SCD 20 women and 19 men, with a mean age of 22.7+/- 7.1 years, hemoglobin level of 95.5+/-14.6g/L and hemoglobin F level of 13.7+/08.6. Patients underwent pulmonary function tests PFT forced expiratory volume in first second [FEV1], forced vital capacity [FVC], and diffusion capacity of carbon monoxide [DLco] data are presented as a percentage of the normal prediction, a 6- minute walk test 6MWT and echocardiography. Dyspnea was assessed using the Borg score. The 6MWT data were compared to body mass index matched healthy controls. Forty-one percent of SCD patients had mild dyspnea at rest and this increased to 61% at the end of the 6MWT. Pulmonary function tests were abnormal in 51%, 36% of patients had a restrictive pattern, 10% had isolated decrease in DLco and 5% had a mixed restrictive-obstrutive pattern. The 6MWD was shorter in SCD patients compared to the controls 368+/-67 versus 407+/-47m, p=0.005. No hematological variables correlated with outcome variables. Chronic pulmonary complications in adult Saudi SCD patients are relatively mild but common. Pulmonary function in these patients differs from that published for African-origin SCD patients. The difference may reflect a different natural history of SCD in the 2 populations. (author)

  18. Patient's awareness of their medical conditions in multi-specialtyoutpatient clinics in Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was to assess the patient's awareness of their medicalconditions, identify the factors affecting their awareness and assesspatient's satisfaction with their doctor's explanations of medicalconditions. A cross-sectional study was conducted in October 2005 in theoutpatient clinics of King Khalid University Hospital in Riyadh, Kingdom ofSaudi Arabia. A self-administered questionnaire was used for data collection.The statistical package for Social Science was used for analysis. Fivehundred and one patients were included in the study. The mean age was45.6+-16.8. Fifty-five percent were female and 29% were highly educated. Mostof the patients (64.1%) knew their diagnoses. This was significantlyassociated with educational level; chronicity of the disease and theawareness of other issues related to their illness such as complications andname of their medications (p>0.05). Few patients (20%) knew complications oftheir diseases. Seventy percent of the patients were satisfied with theirdoctor's explanation of their disease. Knowing the diagnosis (p=0.001) andthe disease complications (p=0.014) were associated significantly withpatient's satisfaction. These figures are less than what they should be.Physicians must be advised of the importance of proper patient education. Inaddition, the lack of proper education by physicians demonstrated in thisstudy should be compensated for by an increase in non-physician basededucation tools. (author)

  19. Assessment of lipid profile in Saudi type 2 diabetic and non-diabetic periodontal patients

    International Nuclear Information System (INIS)

    Objective was to study the extent of periodontal disease in diabetic and non-diabetic periodontitis patients and to investigate the relationship of dyslipidemia and periodontal disease, in diabetic and non-diabetic periodontitis patients. This is a cross-sectional study at the Department of Preventive Dental Sciences College of Dentistry and Department of Physiology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, from February 2003 to June 2004. A total of 90 patients was recruited and divided into 3 equal groups of 30 subjects, with age and gender matched, and divided as follows: group 1 healthy group: periodontally and systemically healthy subjects, group 2 periodontitis group: chronic periodontitis patients with no systemic disease, group 3 diabetic group: chronic periodontitis patients with chronic type 2 diabetes mellitus. Plaque index, bleeding on probing, probing pocket depth PPD, and clinical attachment level CAL were measured at the time of initial examination. The glycated hemoglobin, total cholesterol, low density lipoprotein LDL, triglyceride, high density lipoprotein were also measured. Periodontal parameters PPD and CAL were of significantly higher value in the diabetic patients, when compared to the periodontitis patients p<0.05. The total cholesterol, LDL, and triglyceride were also found to be significantly higher among the periodontitis patients than the healthy subjects p<0.05. This study indicated that type 2 diabetic patients had a higher risk to developed advanced periodontal disease hat the non-diabetic subjects. It also highlighted the association of dyslipidemia in periodontitis patients. (author)

    [Purpose] To review the physical therapy educational program model, professional curriculum, and gender representation at major universities, as well as the quality and scope of physical therapy practice in Saudi Arabia. [Methods] Information regarding course curriculum, gender representation, and the quality and scope of physical therapy practice was collected from six universities in Saudi Arabia, the Saudi Physical Therapy Association, and the Saudi Health Commission. [Results] The first bachelor's degree course of physical therapy was started in Saudi Arabia more than 30?years ago. In the last 10?years, the number of universities offering a bachelor's degree in physical therapy has risen from 6 to 16, of which 14 are governmental and two are private. The 5- to 6?year bachelor's degree program in physiotherapy includes an internship and preparatory prerequisite courses. Postgraduate study in physical therapy was introduced in 2000. Most universities offer segregated physical therapy courses for male and female students. [Conclusion] The enrollment of students in physical therapy programs in Saudi Arabia is gradually increasing. There are many opportunities to extend the scope of practice and contribute to the health needs of the Arab population and international communities. PMID:26157276

  3. Moyamoya syndrome as a risk factor for stroke in Saudi children: Novel and usual associations

    International Nuclear Information System (INIS)

    To report on moyamoya syndrome (MMS) as a risk factor for stroke in a prospective and retrospective cohort of Saudi children. The usual and novel associations of MMS in this cohort will also be described. Children with stroke were evaluated at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February201 to March 2003 (retrospective study). Investigations for suspected cases included hemostatic assays, biochemical, and serological tests. Neuroimaging included CT, MRI, magnetic resonance angiography (MRA), single photon computerized tomography (SPECT) brain scan and conventional cerebral angiography. Moyamoya syndrome was the underlying risk factor for stroke in 6 (5.8%) of the 104 children (aged one month to 12 years). They were 4 females and 2 males. Their first cerebral ischemic event occurred at a mean age of 45 months (median = 44 months, range 17-66 months). In all 6 cases, MMS was associated with an underlying hematologic abnormality or other diseases. Protein C deficiency was identified in one girl and protein S deficiency in another. Two patients had retrospectively, sickle cell disease (SCD) and sickle cell-b-thalassemia (Sb-thalssemia), which had been associated in the latter with membranous ventricular septal defect. Adams-Oliver syndrome (AOS, OMIM 100300) was associated with MMS in an 18-month-old girl. A 4-year-old boy had wrinkly skin syndrome (WWS, OMIM 278250) phenotype. The association of MMS and protein C deficiency was first reported in this cohort of patients, whereas the association of the syndrome with WWS and AOS has not, hitherto, been described. The 3 patients who had MMS associated with protein C deficiency, SCD, and AOS underwent successful revascularization surgery in the form of encephaloduroarteriosynangiosis. Moyamoya syndrome constitutes an important risk factor of stroke in Saudi children. Comprehensive clinical evaluation and investigations, including screening for throphilia and neuroimaging studies are required for the primary diagnosis of the disease and for unraveling other diseases associated with MMS. This will help in managing these patients and in guiding genetic counseling for their families. (author)

    Little is known about the geographic distribution of common cancers in Saudi Arabia. We explored the spatial incidence patterns of common cancers in Saudi Arabia using spatial autocorrelation analyses, employing the global Moran's I and Anselin's local Moran's I statistics to detect nonrandom incidence patterns. Global ordinary least squares (OLS) regression and local geographically-weighted regression (GWR) were applied to examine the spatial correlation of cancer incidences at the city level. Population-based records of cancers diagnosed between 1998 and 2004 were used. Male lung cancer and female breast cancer exhibited positive statistically significant global Moran's I index values, indicating a tendency toward clustering. The Anselin's local Moran's I analyses revealed small significant clusters of lung cancer, prostate cancer and Hodgkin's disease among males in the Eastern region and significant clusters of thyroid cancers in females in the Eastern and Riyadh regions. Additionally, both regression methods found significant associations among various cancers. For example, OLS and GWR revealed significant spatial associations among NHL, leukemia and Hodgkin's disease (r² = 0.49-0.67 using OLS and r² = 0.52-0.68 using GWR) and between breast and prostate cancer (r² = 0.53 OLS and 0.57 GWR) in Saudi Arabian cities. These findings may help to generate etiologic hypotheses of cancer causation and identify spatial anomalies in cancer incidence in Saudi Arabia. Our findings should stimulate further research on the possible causes underlying these clusters and associations. PMID:24351742

    Full Text Available Problem statement: Living in high altitude areas results in chronic hypoxia, which induces complex metabolic and endocrine adaptations. The current study investigated the endocrine responses of male Westar rats chronically exposed to high altitude-induced hypoxia in Abha City, in Southwestern Saudi Arabia. Approach: The rats were separated in to 2 groups of 10 rats. The first group was kept at an altitude of 600 m above sea level in the King Saud University animal house in Riyadh City and designated the low altitude group; the second group of rats was transferred to the King Khalid University animal house in Abha City, which is 2800 m height above sea level and was designated the high altitude group. All rats were housed under the same laboratory conditions and fed the same diet. Blood samples were collected from both groups of animals 45 days after transferring the high altitude group to Abha City. Results: The data revealed that the rats transferred to the high altitude area had significant decreases in serum Thyroid Stimulating Hormone (TSH and testosterone levels and significant increases in the levels of serum cortisol, free Triiodothyronine (T3 and free Thyroxin (T4 compared to rats kept at low altitude. Conclusion: The current study demonstrates that rats chronically exposed to high altitude hypoxia experienced alternations in various hormones. These findings will contribute to a better understanding of human endocrine and metabolic physiology in hypoxic conditions.

  6. Suspected acute appendicitis in female patients: Trends in diagnosis in emergency department in a University Hospital in Western region of Saudi Arabia

    International Nuclear Information System (INIS)

    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 Background and Objectives: One out of five Saudi diabetics develops end-stage renal disease (ESRD. Factors associated with progressive loss of renal function have not been extensively studied and reported in our community. We sought to evaluate the pattern and progression in glomerular filtration rate (GFR and investigate the potential risk factors associated with progression to diabetic nephropathy (DN among Saudi patients. Design and Setting: Hospital-based retrospective analysis of type 2 diabetic patients seen between January 1989 and January 2004 at Security Forces Hospital and King Saud University in Riyadh, Saudi Arabia. Patients and Methods: DN was defined as persistent proteinuria assessed by urine dipstick [at least twice for at least two consecutive years and/or serum creatinine >130 ?mol/L; and/or GFR <60 mL/min/1.73m 2 ]. Results: Of 1952 files reviewed, 621 (31.8% met the criteria for DN, and 294 (47% were males. The mean (SD age of the patients at baseline was 66.9 (11.4 years, and mean duration of diabetes was 15.4 (7.5 years. GFR deteriorated from a baseline value of 78.3 (30.3 mL/min/1.73m 2 to 45.1 (24.1 mL/min/1.73m 2 at the last visit, with a mean rate of decline in GFR of 3.3 mL/min/year. Progression of nephropathy was observed in 455 (73.3% patients, with 250 (40.3% patients doubling their first-hospital-visit serum creatinine level in a mean of 10.0 (6.0 years. At the end of the study, 16.5% of the cohort developed ESRD and were dialyzed. GFR >90 mL/min/1.73m 2 at the first hospital visit; duration of diabetes >10 years; persistent proteinuria; systolic blood pressure >130 mm Hg; and presence of retinopathy were significant markers associated with progression of nephropathy. Conclusion: Diabetic nephropathy tends to be progressive among Saudis, with GFR deteriorating at a rate of 3.3 mL/year and with a doubling of serum creatinine level in 40.3% of patients in 9.9 years.

  11. Congenital and genetic cerebrovascular anomalies as risk factors for stroke in Saudi Arabia

    International Nuclear Information System (INIS)

    To explore the role of and report congenital and genetic cerebrovascular anomalies as risk factors for stroke in a prospective and retrospective cohort of Saudi children. Children with stroke were evaluated at the Division of Pediatric Neurology (Dpn), or were seen as inpatients in the Pediatric Wards at King Khalid University Hospital (KKUH), Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Stroke work-up for each suspected case included hemostatic assays, serological, biochemical and neurophysiological tests. Neuroimaging modalities included routine skill x-rays, CT, MRI, magnetic resonance angiography (MRA) and conventional cerebral angiography. Of 104 children with stroke, congenital and genetic cerebrovascular anomalies were the underlying risk factor in 7 (6.7%). The patients were evaluated at the DPN at a mean age of 66 months (range = 8 months to 11 years, median = 6 years); and they had stroke at a mean age of 48 months (range = 2 months to 10 years, median = 8 months). Four patients had stroke in association with neurocutaneous syndromes. Two had Sturge-Weber syndrome (SWS), one had Klippel-Trenaunay syndrome associated with SWS, and the fourth had neurofibromatosis type 1. Two patients had intracranial hemorrhage secondary to ruptured aneurysm. A girl (aged 9 years and 4 months) had left posterior cerebral artery aneurysm. She was diagnosed to have autosomal dominant polycystic kidney disease following renal ultrasonography. She died 5 months later despite surgical intervention (clipping of aneurysm). The second child was an 8-months-old boy who presented with subarachnoid and intraventricular hemorrhage (IVH) following ruptured anterior communicating artery aneurysm. He recovered with no residual symptoms following successful clipping of the aneurysm. Arteriovenous malformation (AVM) caused IVH in a 7-year-old boy who reported to hospital 5 hours after onset of headache, vomiting, drowsiness, and dizziness. Following drainage of the IVH and stabilization of the patient, the AVM was successfully emboli zed 6 weeks latter. As a group, congenital and genetic cerebrovascular anomalies constitute significant risk factors for stroke in Saudi children. Recognition of these diseases is important since some are treatable and because other family members may be at risk. (author)

    The Kingdom of Saudi Arabia, the largest nation in the Arabian Peninsula is divided into 13 regions, which are of different development levels in terms of both population and public utility infrastructure. More than the other regions, population is high in Al-Riyadh, Makkah Al-Mokarramah, and the Eastern Region, due to urbanization. The current analysis of census results is aimed at understanding (i) regional variations in population and households and (ii) house ownership, type of housing, and housing infrastructure. Saudi Arabia's population is 26,090,555, living in 4,655,127 households with higher concentration in Al-Riyadh, Makkah Al-Mokarramah, and the Eastern Region. One-fourth of the households are in Makkah Al-Mokarrammah while another one-fourth in Al-Riyadh. Households are small with 6 persons in each. The proportion of households in own houses is less than half - mostly Saudi households. Households in the Kingdom live in apartments, traditional houses, villas or floor in a villa with differing proportions across regions and between Saudi and non-Saudi. While apartments are the major type of housing (major regions), traditional houses (Jazan, Al-Baha, Hail, and Aseer regions) and villas (Al-Riyadh region) still exist that are built by concrete (less than four-fifths), block/brick (less than one-fifth), mud (rare), and stone (rare) with varying regional proportions. Infrastructure - electricity, water, and sewage - vary across regions. The major source of electricity is public station followed by private station and private generators. Water source is mainly the public water inside the pipe unit but catchment tank water and well water are used. Three types of sewage system are prevalent in the Kingdom - public sewage, ditch sewage, and private sewage. An inequitable distribution of population across regions shows urbanization, causing an emergence of the modern housing sector influencing house ownership. Developed regions have less ownership, more rentals and office quarters, thus, presuming that development level and migration status are driving house ownership. The impact of infrastructural variations is difficult to interpret as such variations affect the interest of the public sector and customers. A lesser dependence on the public sector requires caution when assessing the situation and when creating policies and provisions to improve quality of life. PMID:25279321

    Full Text Available The aim of this report is to analyze the clinical features, and mutations of the methylmalonyl CoA mutase (MUT gene in 2 patients with methylmalonic aciduria (MMA attending King Saud University Medical City, Riyadh, Saudi Arabia in January 2014. The infants aged 6 days (patient 1 and 3 months (patient 2 with sepsis-like picture, metabolic acidosis, and hyperammonemia were presented. Investigations revealed high propionylcarnitine (C3, elevated urinary methylmalonic acids, 3-hydroxypropionic acids and methylcitrate, consistent with MMA. Sanger-sequencing detected a homozygous novel mutation (c.329A>G; p.Y110C in the MUT gene in patient 1 and a heterozygous in parents. This mutation is predicted to have a damaging effect on the protein structure and function. In patient 2, we detected a novel homozygous nonsense mutation (c.2200C>T; p.Q734X and a heterozygous in parents. This mutation leads to a premature stop-codon at codon 734 of the MUT gene. We identified 2 novel mutations in the MUT gene causing isolated MMA.

    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

    International Nuclear Information System (INIS)

    A quantitative and qualitative study of phytoplankton and zooplankton community and physico-chemical condition of water at two sites in Wa di Haneefah Stream was carried out on a monthly basis from November, 1993 to October, 1994. Water temperature fluctuated between (13.0 deg. - 40.0 deg.) with ph values (7.1 - 7.4). High concentrations (11.3) and 10.13 mgI-1) of dissolved oxygen in two sites were recorded in April. The contents of chloride, carbonate, bicarbonate and sulphate were max mum in March-May. Different phyto planktonic genera present at the two sites belong to the families, Caryophyllaceae, Cacophony, Decasodium and Bacillanophyceae. Bacillariphyceae was the dominating group throughout the study. These plank tons were more prominent in summer and less in winter months. Zoo planktonic genera consisted mainly of protozoa ns, Rotifers and Crustaceans. These zooplankton s were prominent forming a peak in July and trough in January. the distribution of the generic composition of phyto-and-zooplankton was correlated with some of the physico-chemical changes in the environment.

  19. Hemoglobin and hematocrit values of Saudi newborns in the high altitude of Abha, Saudi Arabia

    International Nuclear Information System (INIS)

    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)

  1. Environmental education in Saudi general environment system - an engineering perspective

    International Nuclear Information System (INIS)

    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 Saja Almazrou, Hind Alsahly, Huda Alwattar, Lamya Alturki, Mona Alamri Department of Clinical Pharmacy, College of Pharmacy, King Saud University, Riyadh, Saudi Arabia Background: Most liquid medications are packaged with administration devices, which may be used inappropriately or inaccurately, and sometimes are not used at all. Because of the importance of their proper use for children's health, this study was designed to assess Saudi mothers' experiences with measuring cups, syringes, and droppers for oral liquid medications; to compare accuracy of dosing across these devices; and to determine the effects of mothers' education statuses and pharmacist counseling on dosing accuracy. Methods: This was a cross-sectional study in which mothers were observed as they used a set of commonly available dosing devices which are a dosing cup, syringe, and dropper. Interviews were conducted in the outpatient pharmacy waiting area in several tertiary hospitals and primary clinics in Riyadh, Saudi Arabia between March and April 2013. Saudi women who were mothers of children aged 12 years old or younger and who gave their consent were eligible. Caregivers other than mothers and subjects with vision problems or cognitive/physical disabilities were excluded. We gathered demographic information such as age, number of children, and education status. Subjects were asked if they had had counseling on how to use measuring devices and which device they preferred. Then, the mothers were required to demonstrate how to measure 5 mL of paracetamol (acetaminophen syrup using a cup and a syringe and 1 mL of paracetamol syrup using a dropper. Dosing errors were evaluated visually as overdosing, underdosing, or no error (if the dose was accurate. The data were entered into Microsoft Excel and evaluated using Stata 11.1. Logistic regression was employed to determine relationships. Results: The results revealed that 58% of participants measured an accurate dose of paracetamol using the oral dosing syringe versus 50% of participants using the dropper and 51% using the dosing cup. In general, participants measured more than the intended dose with the dosing cup and less than the intended dose with the dropper. Furthermore, we found that dosing accuracy for each type of instrument was significantly influenced by the mothers' education status. Among the study participants, 77% had not had previous counseling on the use of liquid medication measuring devices. However, dosing errors were not affected by previous counseling. Conclusion: Among mothers using measuring devices, the most accurate doses were found to be measured with the use of the oral syringe, whereas the most errors were made with the use of the dropper. Moreover, education status had a significant effect on dosing errors. The use of a pictographic diagram could improve the mothers' dosing abilities and, thus, reduce dosing errors.

    Full Text Available A prospective study of all native kidney biopsies performed over one year at the Riyadh Armed Forces Hospital, Riyadh, Saudi Arabia was conducted. During this period, 52 kidney biopsies were performed of which, 49 had adequate tissue. All biopsies were processed for light microscopy, immunofluorescence and electron microscopy. The indications for biopsy included the nephrotic syndrome (n=28; 53.8%, asymptomatic proteinuria (n=12; 21.2%, acute nephritic presentation (n=7; 13.5% and asymptomatic hematuria (n=7; 13.5%. Primary glomerulonephritis (GN, excluding IgA nephropathy (IgAN was seen in 34 of the 49 patients (77.6%. Focal and segmental glomerulosclerosis and mesangial proliferative GN were the most common histological diagnoses (31% and 20.4% respectively. Surprisingly, we found a high prevalence of IgA nephropathy (IgAN of 14.5% in comparison with other studies. The prevalence of mesangiocapillary glomerulonephritis (MCGN was low (2% and can only be explained as incidental. The study patients were followed-up for an average of 26.3 weeks. At the end of the observation period, 50% has unchanged course, 37.5% had improved their renal function and protein excretion, and 12.5% had deteriorated. The prognosis of different GN groups and renal survival rate cannot be assessed or calculated in this study because of the relatively short duration of follow-up. Our study further emphasizes the need for a national GN registry and long-term follow-up, in order to recognize the common patterns of GN, their natural histories, the appropriate line of management, and to try and arrest their progression to end-stage renal disease.

    Full Text Available Cooperative language learning (CLL approach was used to encourage second-year university students at the college of languages and translation, at Al-Imam University to learn from their peers so that they could develop their writing skills. Students in CLL-based groups were trained to be more responsible for their learning through developing their personal interaction as well as their linguistic competence in a more relaxed social context. This treatment included sophomore students enrolled in EN 211 course in the second semester of 2013 academic year. Two instruments were used in this study; a pre-post writing test, and an attitude questionnaire. The pre- and post- scores from the test were calculated for descriptive statistics and compared using a Wilcoxon Test. The process of evaluating students’ writings focused mainly on analyzing their mistakes with regard to spelling, using of vocabulary, grammar, punctuation as well as coherence. The findings revealed that the students’ scores in writing were higher for the post-test than the pre-test at the significance level of .001 after being subject to this kind of treatment. However, it must be stated that the degree of improvement was not extremely high as students still made some mistakes with regard to the previously mentioned points. As for the attitude scale, the results obtained proved that the students developed positive attitudes towards using the cooperative learning approach to develop language skills in general and to develop their writing skills in particular.

  5. Epidemiology of chronic kidney disease in the Kingdom of Saudi Arabia (SEEK-Saudi investigators) - A pilot study

    International Nuclear Information System (INIS)

    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).

In the present study, an assessment of the prevalence of self-perceived stress among new medical graduates during their internship training has been performed, and correlations of self-perceived stress with sex, marital status, and clinical rotations have been evaluated.Patients and methods: Interns of the King Khalid, King Abdulaziz, and King Fahd University hospitals in Saudi Arabia were invited to complete a stress inventory known as the Kessler 10, which is used for stress measurement. Apart from stress evaluation, the questionnaire collected personal data, such as age, sex, and marital status, in addition to information relevant to hospital training, assigned duties, and clinical training rotations.Results: Our results showed that nearly 73.0% of interns were under stressed conditions. Most of the interns were affected by a severe level of stress (34.9%, followed by mild (19.3% and moderate (18.8% levels of stress. The stress level was significantly higher (84.0% among female interns in comparison with male interns (66.5% (odds ratio =2.64; confidence interval =1.59–4.39; P<0.0002. There were statistically significant differences between the percentages of male and female interns (P?0.047 at mild, moderate, and severe stress levels. Marital status had no role in causing stress. The highest stress level was reported by interns during the clinical rotations of medicine (78.8%, followed by surgery (74.7%, pediatrics (72.4%, obstetrics and gynecology (70.1%, and emergency (58.3%. The prevalence of stress among the interns and their corresponding clinical rotations in all three hospitals had significant linear correlations (r?0.829, P?0.041. Conclusion: We found a significantly high level of stress among the medical interns. High stress may have negative effects on cognitive functioning, learning, and patient care. Hence, medical interns need support and subsequent interventions to cope with stress. Keywords: medical education, clinical rotation, medicine, surgery, pediatrics

    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.

    Purpose To explore the use of over the counter (OTC) medicines among students during exams in Riyadh City, Kingdom of Saudi Arabia. Method A cross-sectional study was designed; using a self-administered twenty-two item online questionnaire for the students’ convenience and easy response disclosure. Data were analyzed using Statistical Package for Social Science (SPSS) version 13®. Results A total of N = 1596 students participated in this survey, of whom 829 (51.9%) were university students and 767 (48.1%) were high school students. Overall, 80.0% of the respondents disclosed the use of OTC non-steroidal anti-inflammatory drugs for headache and pain relief. In addition, other substances used during the exams were Energy Drinks (5.0%), Flu Medication (5.0%), Vitamins (5.0%) and Antibiotics (5.0%). Female students were found to be more knowledgeable about safety issues concerning the use of OTC medicines (5.11 ± 1.27, p = <0.001) than male students. Ease in access to OTC medicine, availability of pharmacist consultation and advertisement in print and electronic media were the main factors disclosed by the respondents that may result in an increase in the use of OTC products. The use of OTC medicines was generally higher among female students (p = 0.001). Conclusion The use of OTC medication during exams was more among high school and university students. Gender, age and educational institution were found significantly affecting the use of OTC medicines during exams. PMID:24648821

    2000-01-01

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

    2010-01-01

    Full Text Available Background and Aims: Blood donation from glucose-6-phosphate dehydrogenase (G6PD-deficient and sickle cell trait (SCT donors might alter the quality of the donated blood during processing, storage or in the recipient?s circulatory system. The aim of this study was to determine the prevalence of G6PD deficiency and SCT among blood donors coming to King Khalid University Hospital (KKUH in Riyadh. It was also reviewed the benefits and risks of transfusing blood from these blood donors. Materials and Methods: This cross-sectional study was conducted on 1150 blood samples obtained from blood donors that presented to KKUH blood bank during the period April 2006 to May 2006. All samples were tested for Hb-S by solubility test, alkaline gel electrophoresis; and for G6PD deficiency, by fluorescent spot test. Results: Out of the 1150 donors, 23 (2% were diagnosed for SCT, 9 (0.78% for G6PD deficiency and 4 (0.35% for both conditions. Our prevalence of SCT and G6PD deficiency is higher than that of the general population of Riyadh. Conclusion: We recommend to screen all units for G6PD deficiency and sickle cell trait and to defer donations from donors with either of these conditions, unless if needed for special blood group compatibility, platelet apheresis or if these are likely to affect the blood bank inventory. If such blood is to be used, special precautions need to be undertaken to avoid complications in high-risk recipients.

  20. Human papilloma virus-16/18 cervical infection among women attending a family medical clinic in Riyadh

    International Nuclear Information System (INIS)

    Prevalence information is lacking on human papillomavirus type 16 and 18 (HPV-16/18) infections in cervical tissues of women in Riyadh, Saudi Arabia. In addition, there are no observations on progression to cervical intraepithelial neoplasia (CIN). Pap smear and HPV-16/18 detection by PCR followed by Southern blotting was performed on 120 subjects (Saudi and other Arab nationals) during routine gynecological examination. Some HPV-positive was followed for 4 years by Pap smears at every 6 months and by HPV DNA detection at the end of four years. Overall HPV-16/18 prevalence was 31.6%. HPV-16 prevalence alone was 13.3%, HPV-16 as a mixed infection with HPV-18 was 15% and all HPV-18 was 18.3%. Ten subjects had cervical abnormalities with the Pap smear test, six of whom were HPV-16/18 positive, 1 with HPV-16, 1 with HPV-18 and 4 with a mixed infection of HPV-16/18. Of all 23 HPV-16/18-positive subjects, either as individual or mixed infection, followed for years, 7 showed abnormal cytology, 6 at initial examination and 1 during follow-up. Of these 7, 6 reverted to normal without treatment and 1 was treated and became normal after 3 years. None of the subjects progressed to CIN-III. A high prevalence of HPV-16/18 was found, but with low rate of progression to CIN. A significant association with abnormal cytology was found only in patents with HPV-16/18 mixed infection. (author)

    Vision is the ability of seeing with a definite understanding of features, color and contrast, and to distinguish between objects visually. In the year 1999, the World Health Organization (WHO) and the International Agency for the Prevention of Blindness formulated a worldwide project for the eradication of preventable loss of sight with the subject of "Vision 2020: the Right to Sight". This global program aims to eradicate preventable loss of sight by the year 2020. This study was conducted to determine the main causes of low vision in Saudi Arabia and also to assess their visual improvement after using low vision aids (LVD).The study is a retrospective study and was conducted in low vision clinic at Eye World Medical Complex in Riyadh, Saudi Arabia. The file medical record of 280 patients attending low vision clinics from February 2008 to June 2010 was included. A data sheet was filled which include: age, gender, cause of low vision, unassisted visual acuity for long distances and short distances, low vision devices needed for long distances and short distances that provides best visual acuity. The result shows that the main cause of low vision was Optic atrophy (28.9%). Retinitis pigmentosa was the second cause of low vision, accounting for 73 patients (26%) followed by Diabetic retinopathy and Macular degeneration with 44 patients (15.7%) and 16 patients (5.7%) respectively. Inter family marriage could be one of the main causes of low vision. Public awareness should be embarked on for enlightenment on ocular diseases result in consanguineous marriage. Also, it is an important issue to start establishing low vision clinics in order to improve the situation. PMID:26652071

  2. One hundred and thirty-seven living donor pediatric liver transplants at Riyadh Military Hospital. Results and outlook for future

    International Nuclear Information System (INIS)

    To review the results of 137 living donor pediatric liver transplants performed at Riyadh Military Hospital (RMH). Retrospective analysis of the in- and out-patient case notes was carried out. Data were collected regarding age, gender, nationality, diagnosis, type of procedure, complications and survival of the grafts and the recipients. The first 137 living donor pediatric liver transplants were performed in 113 months. The age range was 4.5 months to 14 years. Eighty-four recipients (61%) were male. One hundred and twelve children were Saudi. Left lateral segment was used as allograft in 135 cases. One child each received full left lobe and full right lobe. Six auxiliary partial orthotopic liver transplants were carried out. Familial metabolic liver disorders made the largest group of children needing transplant. The most common indications were progressive familial intrahepatic cholestasis and biliary atresia (45 cases each). The numbers of major complications are: hepatic artery thrombosis (n=8); portal vein thrombosis (n=3); portal vein stenosis (n=3); hepatic vein stenosis (n=3) and biliary strictures (n=4). Fifteen patients died. Three further allografts have been lost. Thus, the overall patient survival rate is 89% and graft survival rate is 86.8%. Living donor liver transplantation is a viable option for children with end-stage liver disease. Metabolic liver disease is the most common indication in Saudi Arabia. The cadaveric donor supply is in shortage and living donation is a practical alternative. The incidence of complications and recipient and graft survival rates of the program at RMH are acceptable, (author)

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

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

    Full Text Available Objective: Data on Hormone Receptor and Her-2/neu expression in breast cancers from Saudi Arabia and Gulf Region is sparse. We undertook this study to describe the patterns of hormone receptor and Her-2/neu protein expression in breast carcinoma and compared them with the histological grade at a University Hospital in Riyadh.Material and Method: We conducted a retrospective study on 164 invasive ductal carcinoma of breast between the year 2002 and 2008. Immunohistochemical analysis for Estrogen and Progesterone Receptor and Her-2/neu was done in all the cases. Fluorescent in situ hybridization for Her-2/neu gene amplification was performed in all 2+ cases and few equivocal 1+ and 3+cases by immunohistochemistry. Correlation between Estrogen and Progesterone Receptor and Her-2/ neu amplification and grade of tumor was calculated.Results: The expression of Estrogen Receptor, Progesterone Receptor were significantly correlated (p<0.001. Also, there was a significant negative correlation between expression of hormone receptor and Her-2/neu amplification. The histologic grade of the tumor was significantly correlated to the expression of both Estrogen and Progesterone Receptor. However, the relationship between Her-2/ neu amplification and grade was not significant and many of the grade III tumor were Her-2/neu negative. In addition, Her-2/neu gene amplification by fluorescent in situ hybridization was observed in 84.6% of breast cancer that were 3+ and in 18.75 % cases that were 2+ by immunohistochemistry.Conclusion: Prevalence of Estrogen and Progesterone Receptor expression and Her-2/neu amplification in breast cancer in the Saudi Arabian population is similar to that reported internationally. There is a negative correlation between hormone receptors expression and Her-2/neu amplification. However not all of the high-grade breast cancers showed Her-2/neu positive status.

    To assess the prevalence of multi-drug resistant (MDR) bacteria causing infections in patients at the intensive care units (ICUs) of Riyadh Military Hospital (RMH), as well as their antimicrobial resistance patterns for one year. A retrospective, cohort investigation was performed. Laboratory records from January to December 2009 were studied for the prevalence of MDR Gram-negative and Gram-positive bacteria and their antimicrobial resistance in ICU patients from RMH, Riyadh, Kingdom of Saudi Arabia. A total of 1210 isolates were collected from various specimens such as: respiratory (469), blood (400), wound/tissue (235), urinary (56), nasal swabs (35), and cerebro-spinal fluid (15). Regardless of the specimen, there was a high rate of nosocomial MDR organisms isolated from patients enrolled in the General ICU (GICU) in Riyadh. Acinetobacter baumannii (A. baumannii) comprised 40.9%, Klebsiella pneumonia (K. pneumonia) - 19.4%, while Pseudomonas aeruginosa (P. aeruginosa) formed 16.3% of these isolates. The P. aeruginosa, A. baumannii, K. pneumoniae, Escherichia coli, Staphylococcus aureus (methycillin sensitive and methycillin resistant), and Staphylococccus coagulase negative are the most common isolates recovered from clinical specimens in the GICU of RMH. Respiratory tract specimens represented nearly 39% of all the specimens collected in the ICU. The most common MDR organisms isolated in this unit were A. baumannii, and K. pneumoniae (Author).

    A national groundwater surveillance programme was started for investigation of natural radioactivity levels in the year 2007. This paper presents (222)Rn radioactivity concentration levels in well waters located in and around the city of Riyadh in Saudi Arabia. Water samples were collected from 171 wells in six different locations. Most of these deep wells have an approximate depth of 1000 m, while shallow wells have a depth of 300 m. The analyses were performed by an ultra-low level liquid scintillation spectrometer equipped with an alpha-beta discrimination device. Efficiency and background calibrations were performed with a (226)Ra aqueous standard homogeneously mixed with a cocktail (high efficiency mineral oil scintillator) which was used after a certain period of time to assure radon equilibrium. The measured (222)Rn activities of deep wells ranged from 0.34±0.05 to 3.52±0.30 Bq l(-1) (average: 1.01±0.10 Bq l(-1)), whereas those of shallow wells ranged from 0.72±0.08 to 7.21±0.58 Bq l(-1) (average: 2.74±0.24 Bq l(-1)). The (222)Rn concentrations levels were found to be in compliance with the proposed national limits of 11.1 Bql(-1) and depend on the water source. PMID:22887118

  11. The Efficiency of Removal of Total Coliforms, Faecal Coliforms and Coliphages in a Wastewater Treatment Plant in Riyadh

    F. A. Fattouh

    2002-01-01

    Full Text Available Limited water resources in Saudi Arabia necessitate the re-use of treated wastewater for irrigation, industrial and recreational purposes. The large numbers of pathogenic agents present in wastewater requires continuous monitoring of the removal of such agents from water prior to re-use. In a one year study total and faecal coliforms and coliphages were estimated in monthly samples from a wastewater treatment plant in Riyadh to evaluate the removal efficiency of such indicators at various levels of wastewater treatment. The efficiency of removal of total coliform (TC and faecal coliform (FC following aeration and sedimentation processes ranged between (18-34% and (17-38% respectively and for coliphages was (4-19%. Chlorinated effluent had negligible counts of TC and FC with an efficiency of removal of (99.2-100% and (99-100% for TC and FC respectively whereas the efficiency of removal of coliphages ranged between (91-100%. As coliphages have been proposed as possible indicators of enteric viruses our study suggests their use as indicators of faecal pollution with traditional coliform indicators and the implementation of treatment measures more effective in virus removal in re-used wastewater. Electron microscopy of selected phage lysates showed the presence of tailed coliphages belonging to families Myoviridae, Siphoviridae and Podoviridae. Polyvalent coliphages able to infect enteric bacteria other than E. coli were also detected.

    Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients? records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4. The estimated prevalence of hypertension in this study was almost 85%. We found no significant difference in the prevalence of hypertension in terms of gender, year of transplantation, duration of transplantation, type of donor, number of previous transplants, diagnosis of renal artery stenosis, etiology of kidney disease, diagnosis of diabetes after transplantation, diagnosis of cerebrovascular accidents, or mean dose of prednisolone and cyclosporine. There was a statistically significant association between increased level of blood pressure and old age (above 50 years, original disease associated with hypertension, history of hypertension on dialysis, acute rejection (once or more, presence of protienuria (more than 0.3 mg/day, abnormality of ECG, or serum creatinine above 300 µmol/L. We conclude that hypertension is highly prevalent in the renal transplant population in Saudi Arabia. Risk factors for the development of hypertension or its complication should be more aggressively approached in order to protect the patients and their grafts alike.

  13. Capacity building in radiopharmaceuticals: Saudi Arabia experience

    International Nuclear Information System (INIS)

    Full text: Undoubtedly, easy availability of radiopharmaceuticals is a key element in application of radioisotopes in health care. And, creating self-sufficiency within the country and the geographical region in manufacturing these time-limited products further enhances this prospect. For obvious reasons, on demand availability and timely distribution of products bodes well for a regional programme. At King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, one such programme began in early 1980s with the installation of the CS-30 (26.4 MeV) cyclotron, with an intention not only to make available the cyclotron products for medical imaging, but also to establish a contemporary research programme in radiotracer development as exemplified by simultaneous installation of a Tomogram (PET scanner) at the time when PET scanning was in its infancy. The first beam on target in 1982 produced the first batch of 67Ga citrate radiopharmaceutical, followed by an addition of various other cyclotron based products over the years. Presently, the Cyclotron Facility routinely produces six cyclotron isotopes (201Tl, 67Ga, 81mKr, 123I, 18F and 13N) which are subsequently formulated into nine different radiopharmaceuticals. Weekly, approximately 25 batches of radiopharmaceuticals are manufactured supporting 35 nuclear medicine facilities within the country and the geographical region. A key motivating and driving force for our Centre has been the goal of becoming a comprehensive radiopharmaceuticals manufacturing facility. Consequently, we introduced in Year 2000 the 131I based products for diagnosis as well as for therapy, including on-request manufacturing of 131I labeled mIBG. Good Manufacturing Practice is the cornerstone of any radiopharmaceuticals manufacturing program. KFSH and RC is a perfect example of how this operational and guiding principle has been applied and evolved over the years, culminating into an effective quality management system for manufacturing radiopharmaceutical products consistently conforming to specifications. The programme building has been 'work in progress' from the onset and continues to be so, particularly in establishment and implementation of strict operational philosophy of GMP and ISO quality management system. We also realized that people are the most important component of any viable program. For efficient functioning, the staff must be well qualified and appropriately trained to achieve the mission of the organization. This has been achieved through staff selection based upon educational background, followed by extensive on-the-job training, as well as didactic education. Consequently, our facility has had a good mix of young and experienced staff. Furthermore, we have availed of the various IAEA's programmes in specific training and fellowships for in depth exposure to other centres. With embarkation upon new programs, continuing education remains a central theme in ultimate success of the entire program. The experience gained over two decades of continuous operation breeds confidence in the staff to achieve the goal of making Saudi Arabia self-sufficient in all its radiopharmaceuticals needs. Continuing with our commitment to make available to the peoples of the country the most contemporary imaging modality, PET scanner was installed at KFSH and RC in 1995. Along with the routine PET work, we have established a team of scientists to perform research work in developing new radiotracers. KFSH and RC's cyclotron facility has continually focused on an overwhelming goal of becoming a comprehensive radiopharmaceuticals manufacturing facility. To this end, the year 2005 is the beginning of establishing just one such facility through expansion of the program that entails: a new building; a state-of-the-art cyclotron (30 MeV; plus a small cyclotron dedicated for PET isotopes production); advanced clean rooms; more importantly, the establishment of the Tc-99m Generators and Cold Kits manufacturing programs. Presentation will entail past, present and future of radiopharmaceuticals manufacturing at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia encompassing programme building and striving for self sufficiency.

    2011-08-01

    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.

  20. Status of medical liability claims in Saudi Arabia

    International Nuclear Information System (INIS)

    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)

    This study focuses on the chemical analysis of the available brands of domestic bottled water in Riyadh City, Saudi Arabia. The distribution of the chemical constituents (major, minor, and trace elements) is determined and compared with the chemical content labeled on the bottles and with drinking water standards of Saudi Arabian, World Health Organization, and U.S. Environmental Protection Agency. The obtained results indicated that except for fluoride and bromate, the concentrations of dissolved salts, soluble cations and anions, nitrate, and trace elements of most bottled waters on sale were within the permissible limits set by standards used. On the other hand, the comparison between determined and reported label values recorded a substantial variation in some parameter values. Results indicated that more than 18 % of the sampled bottled waters exceeded the allowable limits for drinking water. Generated Piper diagrams revealed that the majority of investigated waters were sodium chloride-sulfate type; however, the hydrochemical modeling indicated that all water samples were undersaturated for anhydrite, gypsum, and halite.

  2. Radon activity in Saudi houses

    International Nuclear Information System (INIS)

    Long term measurements of radon's concentrations inside Saudi houses being studied using CR-39 Plastic Track Detectors fixed inside sealed plastic cups. The cups were left for about 7 months in the houses. The measurements were done in different cities of different provinces in the country. The analysis of 636 cups showed that the radon concentration in different cities was ranging from 0.27 pCi/l (in Khobar) to 0.98 pCi/l (in Taif). In exceptional places in Eastern Province, it is found that the lowest concentration was in the University offices (0.13 pCi/l) and the highest was in the University unoccupied houses (0.81 pCi/l). It is found that the ventilation is the main factor affecting the radon concentration in houses. (author)

    Full Text Available During the last decade, the rapid economic development in Saudi Arabia resulted in an unbalanced dietary intake pattern within the general population. Consequently, metabolic syndrome was also documented to be highly prevalent in the Middle-East region. We aimed to examine the relationship between selected dietary nutrient intakes and the prevalence of metabolic syndrome in the general adult population of Riyadh, Saudi Arabia. In this cross-sectional study, 185 adult Saudis aged 19 to 60 years (87 males and 98 females (mean age 35.6 ± 13.2 and 37.6 ± 11.7 years, respectively were included. The criteria for metabolic syndrome were based on the International Diabetes Foundation (IDF criteria, and the dietary food intake was assessed by two 24-h dietary recall methods. The odd ratios (ORs of metabolic syndrome risk across quartiles of selected dietary nutrients were significantly lower for carbohydrates and proteins, as well as for vitamins A, C, E and K, calcium, zinc and magnesium (p < 0.05 for all in the female group with metabolic syndrome than those without. The pattern of daily dietary intake of selected nutrients among the general population of Saudi Arabia raises concern, and this dietary imbalance could increase the risk of metabolic syndrome, particularly in adult Saudi females.

  5. Level of high-sensitivity C-reactive protein in saudi patients with chronic stable coronary artery disease

    International Nuclear Information System (INIS)

    Inflammatory biomarker high-sensitivity C-reactive protein (hsCRP) is an independent predictor of future cardiovascular events and it predicts risk of incident hypertension and diabetes. The aim of this study was to determine the serum levels of the circulating acute-phase reactant high-sensitivity C-reactive protein (hsCRP) in Saudi patients with chronic stable Coronary Artery Disease (CAD). This cross sectional study was conducted in the Department of Physiology and Department of Cardiology, College of Medicine and King Khalid University Hospital, King Saud University, Riyadh between August 2006 and December 2007. One hundred and seven individuals with chronic stable CAD and 33 healthy, age and BMI-matched individuals were studied. Overnight fasting blood samples were collected, and analyzed for total cholesterol (TC), Triglycerides (TG), Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL) and hsCRP in patients with chronic stable CAD. TC (Control 4.41+-0.57 vs CAD 4.28+-1.40, p=0.8394) and LDL levels (Control 2.70+-0.52 vs CAD 2.71+-1.20, p=0.7963) did not differ significantly between the two groups. While there were significant differences in TG (Control 1.13+-0.47 vs CAD 1.84+-1.10, p=0.0135) and HDL levels (Control 1.06+-0.30 vs CAD 0.71+-0.25, p=0.0000). hsCRP levels were significantly higher in patients with CAD (5.0+-4.4) compared to healthy individuals (2.7+-2.7, p=0.0166). Frequency of low risk levels was significantly higher in Controls than CAD patients (24.2% vs 8.4%, p=0.0332) and vice versa for high risk levels (24.2% vs 51.4%, p=0.0110). At average risk levels frequency did not differ significantly (51.5% vs 40.1%, p=0.3429) between control and CAD groups. Saudi patients with stable chronic CAD have higher hsCRP levels compared to healthy individuals. Moreover the prevalence of undesirable risk levels of hsCRP is also higher in CAD patients. (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.

  7. Hyperlipidaemia in Saudi Arabia

    International Nuclear Information System (INIS)

    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)

    Full Text Available Abstract Background A better understanding of the relationships between obesity and lifestyle factors is necessary for effective prevention and management of obesity in youth. Therefore, the objective of this study was to evaluate the associations between obesity measures and several lifestyle factors, including physical activity, sedentary behaviors and dietary habits among Saudi adolescents aged 14–19?years. Methods This was a school-based cross-sectional study that was conducted in three cities in Saudi Arabia (Al-Khobar, Jeddah and Riyadh. The participants were 2906 secondary school males (1400 and females (1506 aged 14–19 years, who were randomly selected using a multistage stratified cluster sampling technique. Measurements included weight, height, body mass index (BMI, waist circumference, waist/height ratio (WHtR, screen time (television viewing, video games and computer use, physical activity (determined using a validated questionnaire, and dietary habits (intake frequency per week. Logistic regression was used to examine the associations between obesity and lifestyle factors. Results Compared with non-obese, obese males and females were significantly less active, especially in terms of vigorous activity, had less favorable dietary habits (e.g., lower intake of breakfast, fruits and milk, but had lower intake of sugar-sweetened drinks and sweets/chocolates. Logistic regression analysis showed that overweight/obesity (based on BMI categories or abdominal obesity (based on WHtR categories were significantly and inversely associated with vigorous physical activity levels (aOR for high level?=?0.69, 95% CI 0.41–0.92 for BMI and 0.63, 95% CI 0.45–0.89 for WHtR and frequency of breakfast (aOR for? Conclusions The present study identified several lifestyle factors associated with obesity that may represent valid targets for the prevention and management of obesity among Saudi adolescents. Primary prevention of obesity by promoting active lifestyles and healthy diets should be a national public health priority.

  10. Bronchiolitis obliterans organizing pneumonia: experience at three hospitals in Riyadh

    International Nuclear Information System (INIS)

    Because reports of bronchiolitis obliterans organizing pneumonia (BOOP) are lacking from the Middle East, we conducted a retrospective review of all histopathologically proven cases of BOOP over 10-year period at three tertiary care hospitals in Riyadh and describe the clinical features and outcome. Charts at the three hospitals were searched using a specific code for BOOP or cryptogenic organizing pneumonia (COP). Lung specimens have to show histological proof of BOOP with a compatible clinical picture. Chest radiographs and high resolution CT scans were reviewed. Twenty cases of biopsy-proven BOOP had well documented clinical and radiograph data. There were 11 males and 9 females (mean age 58 years; range 42-78). The clinical presentation f BOOP was acute or subacute pneumonia-like illness with cough (85%), fever (70%) dyspnea, (85%) and crackles (80%). The most frequent radiological pattern was a bilateral alveolar infiltrate. The most common abnormality on pulmonary function testing (n=14) was a restrictive pattern (11 patients). Most patients (70%) had no underlying cause (idiopathic BOOP). Other associations included thyroid cancer, rheumatoid arthritis, syphilis and Wegner's granulomatosis. Ten patients (50%) had a complete response to steroids, 6 (30%) had a partial response and 3 (15.8) with secondary BOOP had rapid progressive respiratory failure and died. The clinical presentation of BOOP in our patients is similar to other reported series. A favorable outcome occurs in the majority of cases. However, BOOP may occasionally be associated with a poor prognosis, particularly when associated with an underlying disease. (author)

    Middle East Respiratory Syndrome (MERS) is a viral respiratory disease of serious consequences caused by MERS Coronavirus (MERS-CoV). Saudi communities still lack awareness of available protective measures to prevent the transmission of the virus. It is necessary to explore the current information-seeking strategies and preferences for communication tools among the Saudi population to promote dissemination of accurate information. Guided by McGuire's Input-Output Persuasion Model and focusing on input variables (receiver characteristics, sources, message, channel and destination), we explored the current information-seeking strategies and preferences for different communication tools among residents of Riyadh (n = 658). Preferred and sought-after information sources on MERS. Most participants in the sample were female (61.7%), and the majority (98.2%) had internet access at home. The internet was the most commonly used source of information (39.5%) and the most endorsed channel for a MERS awareness campaign. Physicians were the preferred source of information (45.6%), followed by other health care providers (31.3%). In univariate multinomial logistic regression models, males and individuals aged ?27 years were more likely to seek information from the internet than from physicians. Residents of southern and western Riyadh preferred physicians as a credible source of information over the Ministry of Health. The results of this survey provide valuable information on how to reach this population and for understanding how to launch an effective MERS risk communication campaign in a Saudi population.

  12. Management of arbuscular mycorrhizal fungi by growing petunia hybrida (l.) mill. as an ornamental plant in saudi arabia - a case study

    International Nuclear Information System (INIS)

    Arbuscular mycorrhizal fungi (AMF) regarded as ubiquitous soil fungi which help in improving plant growth under harsh conditions. Petunia hybrida is one of the most favorite ornamental plants growing all over the Riyadh city of Saudi Arabia. In the present study, we would like to highlight the Petunia as a mycotrophic plant for the management of mycorrhizal fungi under field conditions. Roots along with rhizosphere soils of P. hybrida were collected from various sites in Riyadh, Saudi Arabia to study AM colonization and biodiversity of AMF. The data obtained in this study indicated that P. hybrida is a very highly mycotrophic plants, and all the samples produced very high colonization with mycelium, vesicles, coiled hyphae and arbuscules. The significant variation was found with the occurrence of mycelium and vesicles among the locations but in case of arbuscules more or less same range of occurrence was found. Only different species of Glomus were observed in all the locations. Glomus showed diversity in all the locations as indicated by the Shanon Diversity Index. As the P. hybrida is a highly mycotrophic plant, so this plant may be grown under harsh condition of Saudi Arabia to manage the plant growth under different stresses viz., water stress, saline soils and heavy metal toxicity conditions.

    Background Drug safety has major implications for patients' lives. However, this concept is still considered new to some healthcare professionals. Objective This study aims to investigate the knowledge and awareness of Saudi healthcare professionals to pharmacovigilance (PV). Setting Governmental and private hospitals at three main cities in Saudi Arabia (Riyadh, Jeddah, and Dammam). Methods A cross-sectional survey among healthcare professionals (pharmacists, physicians, and nurses) within 12 Saudi hospitals was conducted between November and December 2012. The questionnaire consisted of 18 questions assessing the knowledge, awareness, and attitude of healthcare professionals (HCPs) towards science and the concept of PV. Descriptive statistics were used to analyze the data. The data were analyzed using Statistical Analysis Software (SAS 9.3). Main outcome measure Knowledge, attitude and practice of HCPs toward pharmacovigilance. Results Three-hundred and thirty-two healthcare professionals completed the survey (response rate 72 %), 110 (34 %) physicians, 106 (33 %) pharmacists, and 104 (32 %) nurses. More than half of the participants (55 %) did not know the correct definition of PV. Two-thirds of the respondents, 207 (65.5 %), had knowledge of the aim of post-marketing surveillance, yet only 113 (36.9 %) were aware that the National Pharmacovigilance and Drug Safety Center is the official body for monitoring adverse drug reaction in Saudi Arabia. In addition, 34.7 % agreed that lack of time could be a major barrier for reporting. The majority of the respondents (78.4 %) believed that reporting was a professional obligation and hospitals should have a drug safety department. Conclusions There was a limited knowledge of pharmacovigilance that could have affected reporting incidence. Educational intervention and a practical training program need to be applied by the drug regulatory body as well as health authorities to enhance the pharmacovigilance and drug safety culture in Saudi Arabia.

    Full Text Available Objectives: The incidence of type 2 diabetes mellitus (T2DM is growing rapidly in the Saudi population. The purpose of this study was to assess the constructs of the health belief model (HBM as they relate to T2DM lifestyle and prevention behaviours among adolescents. Methods: A cross-sectional study was conducted between May and October 2013 among 426 non-diabetic secondary school students from randomly selected schools in Riyadh, Saudi Arabia. An Arabic version of an adapted English language questionnaire was used to assess knowledge and attitudes related to the severity and prevention of T2DM. A preventative behaviour assessment was also conducted to assess physical activity and dietary habits. Results: The majority of the students (63.4% had at least one diabetic family member. Obesity was more frequent in males compared to females (P = 0.013. Awareness about the importance of maintaining a healthy body weight to prevent T2DM was lower in males than females (P = 0.037, although males engaged in routine exercise more often (P = 0.001. Males were less likely than females to recognise the risks for T2DM, including obesity (P = 0.030, heredity (P = 0.013 and high fat intake (P = 0.001. Conclusion: An alarmingly high number of Saudi students were unaware of T2DM severity and associated risk factors. Female students were more aware of the benefits of T2DM preventative lifestyle behaviours than males, although males engaged in routine exercise more often. Raising adolescents’ awareness about the primary prevention strategies for T2DM should be a public health priority in Saudi Arabia. The HBM could inform further research on diabetes prevention among Saudi adolescents.

  15. Gene expression profiling in woman with women with breast cancer in a Saudi population

    International Nuclear Information System (INIS)

    Objective was to generate consensus gene expression profiles of invasive breast tumors from a small cohort of Saudi females and to explore the possibility that they may be broadly conserved between Caucasian and Middle Eastern populations. This study was performed at King Faisal Specialist Hospital and Research Center, Riyadh, Kingdom of Saudi Arabia, from January 2005 to January 2007. Gene expression profiles were generated from 38 invasive breast tumors and 8 tumor adjacent tissues (TATs) using BD Atlas cDNA expression arrays containing 1176 genes. Results were confirmed by reverse transcriptase polymerase chain reaction and analyzed by 2-dimensional unsupervised hierarchical clustering. The analysis identified 48 differentially expressed genes in tumors from which 25 are already reported by various western studies. Forty-three of these genes were also differentially expressed in TATs. The same data set has been able to distinguish between tumors and the TAT's, interestingly by using only 4 of the differentially expressed genes. Moreover, we were able to group the patients according to prognosis to an extent by hierarchical clustering. Our results indicate that expression profiles between Saudi females with breast cancer and the Caucasian population are conserved to some extent, and can be used to classify patients according to prognostic groups. We also suggest 3 differentially expressed genes (IGHG3, CDK3 and RPS9) in tumors may have a novel role in breast cancer. In addition, the role of TATs is much more essential in breast cancer and needs to be explored thoroughly. (author)

    Achieving a balance between giving access to information and respecting donors' confidentiality is a crucial issue for any biobank, with its large number of samples and associated information. Despite the existence of much empirical literature on confidentiality, there are too few surveys in the Middle East about the topic, particularly in the Saudi context. A survey was conducted of 200 respondents at King Abdulaziz Medical City in Riyadh, Saudi Arabia, among 5 groups of equal size, comprised of researchers, physicians, medical students, donors and laypersons, respectively. The majority of participants agreed that confidentiality is an important issue and that it is well protected in the Saudi biobank. All 5 groups showed different attitudes toward disclosing information to various third parties. They were in favor of allowing treating physicians, and to a certain extent family members, to have access to medical and genetic results from research. No significant differences were found between views on medical and genetic confidentiality. The majority of respondents agreed that confidentiality might be breached in cases with specific justified reasons. Even considering differences in religion, culture and other factors, the results of the study were consistent with those reported in the literature and research conducted in other countries. We therefore place emphasis on the importance of protecting and promoting patient/donor confidentiality and privacy. PMID:26806715

    Full Text Available Background: Hepatitis C affects 2% of Saudi population. Previous local trials showed low response to interferon monotherapy for six-months. Aim: To evaluate biochemical and virological response of interferon-ribavirin combination on naive Saudi patients infected with HCV. Methods: A prospective single armed study was conducted at Riyadh Armed Forces Hospital from July 1999 to July 2002 for fifty patients who have hepatitis C virus (HCV-PCR positive and chronic hepatitis on liver biopsy were started on the combination therapy for one-year. All had HCV-PCR at the end of therapy and at six months follow-up. Results: Thirty-one patients (62% normalized their ALT levels, and 25 patients (50% became HCV-PCR negative achieving end-of-treatment response (ETR. The sustained virological response (SR was achieved in 19 patients (38% at six months follow-up after stopping the treatment. Side effects were mainly flu like syndrome in 36 patients (72%. Conclusion: Combination therapy of interferon alfa-2b plus ribavirin is an effective treatment modality for HCV infected Saudi patients, with tolerable side effects. Our virological response rates are compatible with international published literatures

  18. Epigenetic changes and their clinical relevance in Saudi diffuse large B-cell lymphoma

    International Nuclear Information System (INIS)

    The gene encoding the DNA repair enzyme O6-methylguanine-DNA methyltransferase (MGMT) is transcriptionally silenced by promoter hypermethylation in several human cancers including diffuse large B-cell lymphoma (DLBCL). We explored the aberrant promoter methylation of MGMT in Saudi diffuse large B-cell lymphoma and to investigate MGMT hypermethylation has an effect on patients overall survival.In a retrospective cohort study, 100 cases of DLBCL were collected from the Department of Pathology at King Faisal Specialist Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia. We used methylation specific polymerase chain reaction to analyze the MGMT promoter methylation status in 100 tumor DNA of Saudi DLBCL patients receiving multi drug regimens. Tissue microarray (TMA) of these cases was also constructed. The MGMT protein expression was analyzed immunohistochemically. Molecular data were correlated with clinical outcome. Seventy one percent (71%) of 100 DLBCL patients showed MGMT promoter hypermethylation in their lymphoma. The presence of MGMT methylation was associated with statistically significant increase in the overall survival (p=0.02). The MGMT promoter hypermethylation was independent and a strong prognostic factor. The MGMT promoter hypermethylation appears to be useful marker for predicting survival in patient with DLBCL treated with multi drug regimens including cyclophosphamide, at the same time the study shows that TMA technology is useful for immunohistochemical analysis of large lymphoma populations.

    Full Text Available This study investigated the cross-cultural differences and similarity in health behaviors between Saudi and British adolescents. A school-based cross-sectional study was conducted at four cities in Saudi Arabia (Riyadh and Al-Khobar; N = 1,648 and Britain (Birmingham and Coventry; N = 1,158. The participants (14–18 year-olds were randomly selected using a multistage stratified cluster sampling technique. Measurements included anthropometric, screen time, validated physical activity (PA questionnaire and dietary habits. The overweight/obesity prevalence among Saudi adolescents (38.3% was significantly (p < 0.001 higher than that found among British adolescents (24.1%. The British adolescents demonstrated higher total PA energy expenditure than Saudi adolescents (means ± SE = 3,804.8 ± 81.5 vs. 2,219.9 ± 65.5 METs-min/week. Inactivity prevalence was significantly (p < 0.001 higher among Saudi adolescents (64% compared with that of British adolescents (25.5%. The proportions of adolescents exceeding 2 h of daily screen time were high (88.0% and 90.8% among Saudis and British, respectively. The majority of Saudi and British adolescents did not have daily intakes of breakfast, fruit, vegetables and milk. MANCOVA showed significant (p < 0.05 gender by country interactions in several lifestyle factors. There was a significant (p < 0.001 gender differences in the ratio of physical activity to sedentary behaviors. In conclusion, Saudi and British adolescents demonstrated some similarities and differences in their PA levels, sedentary behaviors and dietary habits. Unhealthy lifestyle behaviors among adolescents appear to be a cross-cultural phenomenon.

  1. Saudi Arabia : emerging with influence

    International Nuclear Information System (INIS)

    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

    The oocysts of Caryospora biarmicusis sp.n. is described from the feces of the lanner falcon, Falco biarmicus, from the falcon market in Riyadh City, Saudi Arabia. Sporulated oocysts are ovoid in shape, measuring 40.2 x 34.7 (37.5-42.4 x 32.9-35.7) microm; shape index (L/W) is 1.16 (1.08-1.31) microm. The oocyst wall is smooth and bi-layered. Micropyle and polar granule are absent, but an oocyst residuum is present. Sporocysts are spheroid, 20.1 (18.6-21.3) microm; with a smooth single-layered wall, lacking Stieda body. Sporocyst residuum is present as numerous small granules. Sporozoites are stout with a large single refractile body. PMID:21634236

  5. Environmental isotopes in North African groundwaters; and the Dahna sand-dune study, Saudi Arabia

    International Nuclear Information System (INIS)

    I. North Saharian palaeowaters were mainly formed during a long humid period between 50,000 and 20,000 years BP., which was followed by a cool dry period from 20,000 to 14,000 years BP. These palaeowaters show a significant west-east decrease in deuterium and 18O because of past groundwater formation by local rainfall from the western drift. Sahel zone groundwaters seem to show meridional variation of deuterium and 18O due to a tropical convective influence. II. A computer model estimate of the alternate play between rainwater infiltration and evaporation in the Dahna sand-dune (near Riyadh, Saudi Arabia) yields a mean annual groundwater recharge of 20 mm annually which agrees with that obtained from bomb tritium vertical profiles of the sand moisture. The model also describes the deuterium and 18O profiles. (author)

    Air pollution exposure has been shown to be associated with an increased risk of specific cancers. This study investigated whether the number and incidence of the most common cancers in Saudi Arabia were associated with urban air pollution exposure, specifically NO2. Overall, high model goodness of fit (GOF) was observed in the Eastern, Riyadh and Makkah regions. The significant coefficients of determination (r2) were higher at the regional level (r2 = 0.32-0.71), weaker at the governorate level (r2 = 0.03-0.43), and declined slightly at the city level (r2 = 0.17-0.33), suggesting that an increased aggregated spatial level increased the explained variability and the model GOF. However, the low GOF at the lowest spatial level suggests that additional variation remains unexplained. At different spatial levels, associations between NO2 concentration and the most common cancers were marginally improved in geographically weighted regression (GWR) analysis, which explained both global and local heterogeneity and variations in cancer incidence. High coefficients of determination were observed between NO2 concentration and lung and breast cancer incidences, followed by prostate, bladder, cervical and ovarian cancers, confirming results from other studies. These results could be improved using individual explanatory variables such as environmental, demographic, behavioral, socio-economic, and genetic risk factors. PMID:24192792

    Aim To assess the knowledge, attitudes, and perceptions of Saudis towards participating in clinical trials (CTs). Methods A cross-sectional study was conducted on 232 Saudi adult patients and their companions visiting adult outpatient clinics at King Fahad Medical City, Riyadh, Saudi Arabia. Data were collected using a self-administered questionnaire based on information obtained from the literature. The questionnaire was divided into four sections, one covering the respondents’ demographics, and the other three assessing knowledge, attitudes, and perceptions towards participating in CTs. Results A total of 148 (63.8%) respondents were males, and 52 (22.4%) participants had been invited to participate in a CT previously. Of those, 39 (75%) participated. Knowledge about the essential elements of informed consent ranged from 55.7% (number of participants needed) to 85.7% (confidentiality of personal information). The majority (163, 73.8%) of respondents was willing to participate in a CT after consulting their family physician and 130 (58.0%) respondents would be motivated to participate in a CT if they were healthy. Only 36.8% of the respondents believed that patients who participated in a CT received the best care. Moreover, 110 (48.7%) respondents believed that research was conducted in a responsible and ethical manner. Conclusions The present study assessed the current understanding of CTs among Saudi participants. Although the majority of participants had an acceptable level of knowledge about CTs, they exhibited conditional attitudes and misperceptions towards participating in a CT. Increased patient awareness may improve patients’ attitudes towards ethical conduct of CTs. PMID:26848750

  12. New age estimations for the western outer city wall of ancient Tayma (NW Saudi Arabia) based on OSL and radiocarbon data and geomorphologic evidence

    Since 2004 tremendous progress has been achieved in deciphering the cultural genesis of the Tayma oasis (NW Saudi Arabia), due to the joint investigations of the German Archaeological Institute Berlin (DAI), the General Commission for Tourism and Antiquities, Kingdom of Saudi Arabia, and the Department of Archaeology and Epigraphy, King Saud University Riyadh. Nevertheless, archaeological research is still suffering from a lacking locally-based absolute chronology of buildings. The pattern of ancient constructions at Tayma is dominated by a prominent city wall system surrounding the ancient town center (Qraya) and stretching 15 km around the oasis. Its internal structure indicates several building periods, i.e. phases of wall modification or extension of the entire system. So far, according to silex and carnelian fragments included in the mud bricks and a previous 14C age of charcoal remains from the central excavation district (wall section at Area A), an initial construction date of the wall between the late 3rd and the early 2nd millennium BC seemed likely. At the excavated western outer city wall a new systematic dating approach - combining the optically stimulated luminescence (OSL) and 14C methods - has been applied to generate a reliable age for the oldest branch of the wall system which nowadays is covered by aeolian sand. The dune deposit is genetically related to the existence of the wall and, therefore, dating its accumulation provides termini ante quem for the construction of the wall. Five OSL dates were generated from the dune deposit providing ages between 4,900 and 3,500 yrs. Two radiocarbon ages support the dating sequence and also contribute to its consistency. By combining the results with geomorphologic evidence we draw the following conclusions: Initial settlement activities at Qraya were accompanied by a regulation of wadi dynamics and the construction of the outer city wall, indicated by the abrupt boundary between the pre-settlement alluvial silt and the overlying wall-related dune deposit. According to the OSL and 14C dating results from this deposit, the wall section at C1 (western part of the ancient settlement, north of Area A) dates back to the middle of the 3rd millennium BC or even earlier. Furthermore, the burying of the still existing remains of the city wall at C1 by sand was already completed at the beginning of the 2nd millennium BC.

    Full Text Available Objective: Data on hormone receptor and Her2/neu expression in breast cancers from Saudi Arabia and Gulf Region is sparse. We undertook this study to describe the patterns of hormone receptor and Her2/neu protein expression in breast carcinoma and compared them with the histological grade at a university hospital in Riyadh.Material and Method: We conducted a retrospective hormone receptor and Her2/neu study on 164 histologically confirmed invasive ductal carcinoma of the breast between the year 2002 and 2008. Immunohistochemical analysis for estrogen receptor, progestrone receptor and Her2/neu was done in all the cases. Fluorescent in situ hybridization (FISH for Her2/neu gene amplification was performed in all 2+ cases and a few equivocal 1+ and 3+cases by immunohistochemistry. The results were then compared in a blinded fashion. Correlation between Estrogen Receptor, Progesterone Receptor and Her2/neu amplification and grade of tumour were calculated.Result: The prevalence of estrogen receptor, progestrone receptor and Her2/neu overexpression were 64.6%, 57.3% and 35.3% respectively. The expression of estrogen receptor and progestrone receptor were significantly correlated (p<0.001. There was also a significant negative correlation between expression of hormone receptor and Her2/neu amplification. The histological grade of the tumour was also significantly correlated to the expression of both estrogen receptor and progestrone receptor. However, the relationship between Her2/neu amplification and grade of tumour was not significant and many of the grade III tumours were Her2/neu negative. In addition Her2/neu gene amplification by FISH was observed in 84.6% of breast cancers that were 3+ and in 18.75% of the cases that were 2+ by immunohistochemistry.Conclusion: The revalence of estrogen receptor, progestrone receptor expression and Her2/neu amplification in breast cancers in Saudi Arabian population is similar to that reported internationally. There is a negative correlation between hormone receptors expression and Her2/neu amplification. However, not all high-grade breast cancers showed Her2/neu positive status.

  15. Open-Heart surgery and cerebrovascular accident: retrospective study at King Khalid University Hospital

    International Nuclear Information System (INIS)

    Stroke after coronary by-pass grafting (CABG) is often disabling. The incidence of ischemic stroke may approach 3% to 5%. Several risk factors have been identified including previous history of stroke, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation. Objective was to determine the incidence and risk factors of neurological deficit after open heart surgery. Retrospective study was done during the period 1992-1995 at the King Khalid University Hospital, Riyadh, Saudi Arabia. There were 350 patients who were subjected to (CABG), 10 patients (2.8%) found to suffer from cerebrovascular accidents (CVA) following open-heart surgery. In 8 patients, the complaint lasted more than 24 hours (stroke), while 2 patients developed transient ischemic attacks (TIA). Five factors were found to be associated with increased risk of post cardiac surgery CVA. These factors are postoperative atrial fibrillation, carotid bruit, past history of heart failure, past history of CVA and smoking. The authors concluded that it is necessary to start a prospective study to verify the area of improvement with regards to technique, selection of patients and mode of perfusion during cardiopulmonary bypass (CPB) Arabia.

  20. Present status of the Old World screwworm, Chrysomya bezziana (Diptera: Calliphoridae), in the Middle Region of Saudi Arabia

    International Nuclear Information System (INIS)

    Full text: The Old World screwworm Chrysomya bezziana (Diptera: Calliphoridae) was reported in animals from the Middle Region of Saudi Arabia in 1998. Incidences of larval myiasis in sheep and seasonal activity of adult C. bezziana in the Riyadh Region were investigated during the period of Oct. 2001-June 2003. 3,712 sheep were examined and only 73 were found infested with C. bezziana larvae. Among the 73 infested sheep, 44 (60%) were young (less than 6 months old) and 29 (40%) were adults (above 6 months): 48 (66%) were females and 25 (34%) were males; and the mortality rate was 26% (12 young and 7 old sheep died). The infestation rates with C. bezziana were highest during March-May (60%) and Sept-Nov. (31.5%) when the temperature and humidity are optimum. During the hot dry and cold seasons infestation rate were low (5% and 1.5% respectively). During the same period, the seasonal activity of adult C. bezziana was also investigated using sticky traps baited with Swomlure-4. The baited traps were used twice a month. Unfortunately, only 19 adult flies were caught. From these results it is clear that C. bezziana is of no economic importance in the Middle Region of Saudi Arabia because of the long dry hot weather, which is unfavourable for larval development and adult survival. Further studies on the biology, distribution and economic importance of C. bezziana and other fly causing myiasis in Saudi Arabia are required. (author)

  1. Receptor modelling study of polycyclic aromatic hydrocarbons in Jeddah, Saudi Arabia

    International Nuclear Information System (INIS)

    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

    2011-01-01

    BACKGROUND AND AIMS: Saudi Arabia falls in the high prevalent zone of ?? and ? thalassemias. Early screening for the type of thalassemia is essential for further investigations and management. The study was carried out to differentiate the type of thalassemia based on red cell indices and other hematological parameters. MATERIALS AND METHODS: The study was carried out on 991 clinically suspected cases of thalassemias in Riyadh, Saudi Arabia. The hematological parameters were studied on Coulter STKS. Cellulose acetate hemoglobin electrophoresis and high-performance liquid chromatography (HPLC) were performed on all the blood samples. Gene deletion studies were carried out by restriction fragment length polymorphism (RFLP) technique using the restriction endonucleases Bam HI. STATISTICAL ANALYSIS: Statistical analysis was performed on SPSS 11.5 version. RESULTS: The hemoglobin electrophoresis and gene studies revealed that there were 406 (40.96%) and 59 (5.95 %) cases of ? thalassemia trait and ? thalassemia major respectively including adults and children. 426 cases of various deletion forms of ? thalassemias were seen. Microcytosis was a common feature in ? thalassemias trait and (-?/-?) and (--/??) types of ? thalassemias. MCH was a more significant distinguishing feature among thalassemias. ? thalassemia major and ? thalassemia (-?/??) had almost normal hematological parameters. CONCLUSION: MCV and RBC counts are not statistically significant features for discriminating between ? and ? thalassemias. There is need for development of a discrimination index to differentiate between ? and ? thalassemias traits on the lines of discriminatory Indices available for distinguishing ? thalassemias trait from iron deficiency anemia.

    Full Text Available Objective: The objective of this study was to assess the prevalence of polypharmacy (PP and the associated factors in medical outpatients. Materials and Methods: A cross-sectional, observational, descriptive study was carried out in adult medical outpatients attending internal medicine clinics at King Abdulaziz Medical City, Riyadh, Saudi Arabia from 1 March 2009 to 31 December 2009. PP was defined as the concomitant use of ?5 medications daily. The number of medications being currently taken by patient was recorded. Effect of patients? age, gender, educational level, number of prescribers, disease load and disease type on PP was assessed by multivariate analysis using Statistical Package for Social Sciences Incorporated (SPSS Inc Version 18. Results: Out of 766 patients included in the study, 683 (89% had PP. The mean number of prescribed medications, oral pills and doses was 8.8, 9.6 and 12.1, respectively. Factors significantly associated with PP included age (?61 years, disease load and the number of prescribers. Gender had no impact on PP while education beyond primary education significantly decreased PP. Hypertension, diabetes mellitus and dyslipidemia alone and as a cluster increased PP. Conclusion: We found an extremely high level of PP in medical outpatients at our tertiary care center. The impact of PP on medication compliance and control of underlying diseases in Saudi Arabia is unknown and needs to be studied at different levels of care.

    Background Dyslipidemia, a known cardiovascular risk factor, is extremely common among Saudis, both adults and children. The impact, however, of dyslipidemia and several other lipid disorders in patients with congestive heart failure in this particular population has not been documented. This study aims to fill the gap. Methods This retrospective, single center study was conducted at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Of the 500 cases seen during the period between 2002 and 2008, 392 were included in the study. Charts were reviewed and information on medical history, medications, and lipid status were documented. Results Low HDL-cholesterol level was the most common lipid disorder with 82.9%, followed by hypertriglyceridemia (35.2%), atherogenic dyslipidemia (27.8%), and hypercholesterolemia (9.2%). Diabetes mellitus was the single most significant predictor of mortality (p = 0.001). Among the lipid disorders, only low levels of HDL-cholesterol contributed to significant mortality risk [OR 1.29 (Confidence Interval 1.04–1.59) (p-value < 0.01)] adjusted for age, gender and statin use. Conclusion The results of this study suggest that emphasis should be on the elevation of HDL-cholesterol levels among subjects with congestive heart failure, without compromising any ongoing management of LDL-lowering drugs. Management should not be limited to conventional statin use and should promote other treatments to elevate HDL-cholesterol levels. PMID:25870502

    Full Text Available Aim: Four viral pathogens, bovine viral diarrhea virus (BVDV, and bovine herpes virus type 1 (BHV-1, bovine parainfluenza type 3 virus (PI-3V, bovine respiratory syncytial virus (BRSV are mainly associated with bovine respiratory diseases that cause major economic losses in the dairy cattle industry. This study aimed to document exposure of cattle in Saudi Arabia to infectious BVDV, BHV-1, PI-3V and BRSV viruses in non vaccinated cattle in order to obtain epidemiological and immunological information. Materials and Methods: In the present study, 460 random serum samples obtained from non vaccinated cattle in five districts (Riyadh, Eastern Province, Jizan, Najran, Asir of Saudi Arabia between January to March 2011. These samples were tested for presence of antibodies against BVDV, BHV-1, BRSV and PIV-3 by commercial indirect ELISA kits. Results: Our findings displayed that Seropositivity rates were 26 % for BVD, 17.4 % for BHV-1, 69.1 % for PI-3V and 75.6 % for BRSV in the sampled population. In addition, coinfections with more than one virus were considerably common among non-vaccinated dairy cattle. Conclusion: These results indicate that exposure to these agents is common within the study areas. Preventive and control measures against these infectious agents should therefore be adopted.

    New cases of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) were reported in Gulf countries in 2014, and to date, it has reportedly infected 837 people and killed 291 globally. Awareness of an individual's knowledge and being able to predict his or her behavior is crucial when evaluating clinical preparedness for pandemics with a highly pathogenic virus. The aim of this study was to identify awareness, attitudes, and practices related to MERS-CoV among the public in Saudi Arabia. A cross-sectional study of 1147 adult subjects recruited from various shopping malls in Riyadh was conducted. All the subjects were interviewed using a questionnaire that tested their knowledge, attitudes, and use of precautionary measures in relation to the MERS-CoV pandemic. The majority of the participants showed high levels of concern and had utilized precautionary measures. After adjusting for other variables, gender was the only significant predictor of the level of concern (P < .001), while knowledge was the significant predictor of both the level of concern and precaution (P < .001). High concern translated into a higher compliance with precautionary recommendations. Frequent communication between health care providers and the public is recommended to help dispel myths about the disease and to empower the public with the information needed to help the Saudi government in containing the disease outbreak.

    Population of the State of Kuwait is composed of three genetic subgroups of inferred Persian, Saudi Arabian tribe and Bedouin ancestry. The Saudi Arabian tribe subgroup traces its origin to the Najd region of Saudi Arabia. By sequencing two whole genomes and thirteen exomes from this subgroup at high coverage (>40X), we identify 4,950,724 Single Nucleotide Polymorphisms (SNPs), 515,802 indels and 39,762 structural variations. Of the identified variants, 10,098 (8.3%) exomic SNPs, 139,923 (2.9%) non-exomic SNPs, 5,256 (54.3%) exomic indels, and 374,959 (74.08%) non-exomic indels are 'novel'. Up to 8,070 (79.9%) of the reported novel biallelic exomic SNPs are seen in low frequency (minor allele frequency T] from CYP4F2 gene [MIM:*604426]) associated with warfarin dosage levels [MIM:#122700] required to elicit normal anticoagulant response; and a 3' UTR SNP (rs6151429 [22:g.51063477T>C]) from ARSA gene [MIM:*607574]) associated with Metachromatic Leukodystrophy [MIM:#250100]. Hemoglobin Riyadh variant (identified for the first time in a Saudi Arabian woman) is observed in the exome data. The mitochondrial haplogroup profiles of the 15 individuals are consistent with the haplogroup diversity seen in Saudi Arabian natives, who are believed to have received substantial gene flow from Africa and eastern provenance. We present the first genome resource imperative for designing future genetic studies in Saudi Arabian tribe subgroup. The full-length genome sequences and the identified variants are available at ftp://dgr.dasmaninstitute.org and http://dgr.dasmaninstitute.org/DGR/gb.html. PMID:24896259

      - Data collection is difficult to any network analysis because it is difficult to create a complete network.  It is not easy to gain information on terrorist networks.  It is fact that terrorist organizations do not provide information on their members and the government rarely allows researchers to use their intelligence data (Ressler S., 2006).  Very few researchers (Krebs, V., 2002, Sageman, M., 2004 and Rodriguez, J. A., 2004) collected data from open sources, and to the best of our knowledge, no knowledge base is available in academia for the analysis of the terrorist events.   To counter the information scarcity, we at Software Intelligence Security Research Center, Aalborg University Esbjerg Denmark designed and developed terrorism knowledge base by harvesting information from authenticated websites.   In this paper we discuss data collection and analysis results on our on-going research of Investigative Data Mining (IDM). In addition, we present iMiner Information Harvesting System and describe how intelligence agencies could be benefited from detecting hierarchy in non-hierarchical terrorist networks.  In this paper we present results of detection of hidden hierarchy of Riyadh Bombing Terrorist Network as a test bed.

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 Objectives: To estimate the prevalence of clopidogrel non-response and identify its risk factors among Saudi patients. Methods: This cross-sectional study was conducted at Prince Sultan Cardiac Center, Riyadh, Kingdom of Saudi Arabia between January and June 2013, to assess the degree of platelet inhibition using the VerifyNow assay (Accumetrics, San Diego, CA, USA after receiving clopidogrel standard loading dose. Clopidogrel resistance was defined as ?15% platelet inhibition or greater than 213 P2Y12 reaction units (PRU. Results: Three hundred and four patients were included in the study. The mean age was 60.3 ± 11.4 years, and 73% were males. Clopidogrel doses were 300 mg (57%, 600 mg (27%, and 75 mg (16%. All patients used aspirin (81 mg in 94%. Approximately 66% (200/304 showed in vitro clopidogrel non-response, 54% had low platelet inhibitions, and 61% had high post-loading PRU. Using multivariate regression analysis that included all significant characteristics; only diabetes (odds ratio [OR]: 2.36, 95% confidence interval [CI]: 1.30-4.27, p=0.005 and higher preloading PRU (OR: 2.39, 95% CI: 1.40-4.11, p=0.002 remained significantly associated with higher clopidogrel non-response while myocardial infarction (OR: 0.34, 95% CI: 0.15-0.81, p=0.014 remained significantly associated with lower clopidogrel non-response. The associations of morbid obesity and diuretics use with higher clopidogrel non-response were slightly attenuated. Conclusion: Our findings indicate a high rate of clopidogrel in-vitro non-response among Saudi patients undergoing coronary angiography.

    Background: The main objectives of this study were to: (1) Evaluate the levels of thyroid hormones and glycosylated hemoglobin (HbA1c) among patients, (2) correlate between thyroid hormones and HbA1c and different types of lipids and HbA1c among diabetic patients. Materials and Methods: A retrospective chart review study was conducted at Department of Clinical Chemistry, King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia, during the period from August 2014 to December 2014, including 100 male and female patients diagnosed with diabetes mellitus (DM) type 2 and excluding patients with DM type 1. These patients were admitted to the hospital in 2013. Biochemical laboratory results were retrieved from biochemistry laboratory database while age and sex of patients were retrieved from patient files. Statistical analysis was performed using SPSS software conducting frequency analysis and correlation test. Results: The result showed increased mean levels of HbA1c (8.4%) and normal level of thyroid stimulating hormone (TSH) (4.5 mlU/L) and T4 (14.1 pmol/L). The results also showed a weak positive correlation between HbA1c and TSH (r = 0.212, P = 0.034) and insignificant correlation with thyroxin T4 (r = ?0.018, P = 0.855). There was a weak positive correlation between HbA1c and total cholesterol and low density lipoprotein (r = 0.258, P = 0.001), (r = 0.297, P = 0.003), respectively. Conclusion: It is concluded that increased blood glucose could trigger anterior pituitary gland to increase secretion of TSH, whereas there was no direct correlation between increased glycemic index and the rate of thyroxine secretion. Furthermore, it is concluded that there is an association between blood glucose and some lipid markers.

  2. The Effect of Temperature and Salinity on the Germination of Calligonum comosum L Her (Polygonaceae) in Two Different Populations in Saudi Arabia

    International Nuclear Information System (INIS)

    Different degrees of temperature and salinity have been studied to evaluate their effects on the seed germination of Calligonum comosum L Her grown in two different populations in Saudi Arabia. These two sites have been chosen in Saudi Arabian deserts, one in Nefoud El-Shakika south Onyza city on Najd plateau and the second west El-Dahnaa in the way between El-Riyadh and El-Damam cities, Kingdom of Saudi Arabia. Each of these locations were dominated by Calligonum comosum L Her beside other species such as Artemisia monosperma, Ephedra elata and Haloxylon ammodendron. These two deserts are completely deferent in their climatic and edaphic factors, since climatic diagrams and soil chemical analyses have been investigated. Twenty plants, with plenty of fruits, from each site have been chosen and collected from each site during April 2003. Germination was in two variables, the number of days to start germinating and the final percentage of germination. The most favorable temperature was 10/20 degree C at seed depth 0.5 cm. and irrigation system every 48 hours 50 ml. dist. water supply. Meanwhile, the seeds in the two locations prefer non-saline media, as the best results obtained at salt concentration 0.0. Whereas the germination start again in Nefoud El-Shakika seeds only at salty media by the concentration of 150 mlmol. Nacl. The results have been discussed according to both differences in climatic and soil characters. (author)

    Full Text Available This study aims at describing the system of SPA (Saudi pidginized Arabic as produced by AFEs (Asian foreign expatriates working in Saudi Arabia with specific reference to universal characteristics of reduction and simplification in the system of morpho-syntactic structure of Saudi Arabic. The study is based on data collected through a semi-structured interview technique probing into the features of SPA system. Thirty informants were randomly selected from among expatriates working in Saudi Arabia and belonging to different linguistic backgrounds – Urdu, Hindi, Bengali, Tagalog, Indonesian, and Malayalam- as representatives of AFEs. The study showed that the AFEs tend to use simplified and reduced system of SA in order to communicate with its native speakers. This was reflected in producing variations of sentence word order that are not compatible with the sentence word order of SA, reduced inflectional verb forms and simplified noun phrase lacking agreement within its structure. The study concluded with the following implications: 1 SPA could be considered as an emerging contact variety among Asian expatriates in Saudi Arabic; 2 it has universal characteristics of reduction and simplification as shown in its structural system; 3 substrate languages play an essential role in the formation of the SPA.Keywords: Pidgin, simplification, reduction, SPA, AFEs, SA.

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

  6. Saudi Arabia plans future strategy

    International Nuclear Information System (INIS)

    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.

    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.

    Full Text Available The study investigated the academic literacy socialization of students at U.S. universities from the Gulf Region—Oman, Saudi Arabia, and United Arab Emirates (UAE. International students were contacted and asked if they would participate in the project. Fifty three students responded to the survey and interview, 77% of the respondents were  male and 23% were female. The results of the study found that the Gulf Coast students studying in the U.S. shared similar experiences in how they socialized academically, however, noticeable differences appeared between linguistic abilities and grammar challenges. When the students were asked if their linguistic abilities prevented them from participating in classroom discussion, the Saudi participants were the only group that said ‘Never’. Likewise, when the researchers inquired about grammar challenges, an interesting dissimilarity revealed itself. The Saudi sample indicated it was very easy while the UAE participants specified that it was somewhat difficult and each group had the same percentage of respondents. Although differences between the students were observed, similarities were also revealed. For instance, all the students did not mind working academically with the opposite sex. The results of this study help in the understanding on how to help students from the Gulf Coast academically assimilate into the American educational system.

    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)

  13. Osteoporosis among male Saudi Arabs: a pilot study

    International Nuclear Information System (INIS)

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

This requires both prescription of an adequate dose of HD and regular assessment that the delivered treatments are also adequate. Online conductivity monitoring using sodium flux as a surrogate for urea allows the repeated noninvasive measurement of Kt/V on each HD treatment.Methods: We prospectively studied 17 (9 males, 8 females established chronic HD patients over an eight-week period (408 treatments. A pre- and post-dialyzer measurement of the conductivity is performed by two mutually independent temperature-compensated conductivity cells equipped with Fresenius 4008 S® dialysis machines. Urea reduction was measured (once a week by a single pool calculation using immediate post-treatment sampling. No changes were made to any of the dialysis prescriptions over the study period. Values of calculated Kt/V and simultaneously obtained online Kt/V were compared.Results: There was a statistically significant difference between calculated Kt/V and online Kt/V over the study period. The mean calculated Kt/V was 1.37 ± 0.09, and mean online Kt/V 1.02 ± 0.15 (P = 0.000, calculated Kt/V ? 1.2 was achieved in all our patients while online Kt/V ? 1.2 was achieved in only 17.64 %.

    Adverse childhood experiences (ACEs) have been linked with risky health behaviors and the development of chronic diseases in adulthood. This study examined associations between ACEs, chronic diseases, and risky behaviors in adults living in Riyadh, Saudi Arabia in 2012 using the ACE International Questionnaire (ACE-IQ). A cross-sectional design was used, and adults who were at least 18 years of age were eligible to participate. ACEs event scores were measured for neglect, household dysfunction, abuse (physical, sexual, and emotional), and peer and community violence. The ACE-IQ was supplemented with questions on risky health behaviors, chronic diseases, and mood. A total of 931 subjects completed the questionnaire (a completion rate of 88%); 57% of the sample was female, 90% was younger than 45 years, 86% had at least a college education, 80% were Saudi nationals, and 58% were married. One-third of the participants (32%) had been exposed to 4 or more ACEs, and 10%, 17%, and 23% had been exposed to 3, 2, or 1 ACEs respectively. Only 18% did not have an ACE. The prevalence of risky health behaviors ranged between 4% and 22%. The prevalence of self-reported chronic diseases ranged between 6% and 17%. Being exposed to 4 or more ACEs increased the risk of having chronic diseases by 2-11 fold, and increased risky health behaviors by 8-21 fold. The findings of this study will contribute to the planning and development of programs to prevent child maltreatment and to alleviate the burden of chronic diseases in adults. PMID:24974249

  16. The Jinadriyah anticlines: a surface model for oil fields in eastern Saudi Arabia

    International Nuclear Information System (INIS)

    Mesozoic oil in Saudi Arabia exists in north/south-oriented anticlines. Such anticlines are usually studied using subsurface data. The present study introduces, for the first time in Saudi Arabia, a surface analog for these anticlines. The study covers two northerly oriented anticlines located in the Jinadriyah area at 15 km to the northeast of the Riyadh city. They are named herein the North and South Jinadriyah anticlines. The outcrops in both anticlines belong to the Lower Cretaceous Yamama Formation which consists of limestone in its lower part and limestone with shale in its upper part. The study included initially detailed interpretation of Google Earth and Landsat TM images to map the structural pattern of the anticlines. Detailed field mapping confirmed the satellite image interpretation and helped describe the geometry of the two anticlines in detail. The 3.5-km-long South Jinadriyah anticline is an open doubly plunging asymmetric anticline. The western flank is dissected by 13 minor reverse faults of north-south orientation. The North Jinadriyah anticline is about 5.5 km long and is relatively more complex than the South Jinadriyah anticline. It consists of northern, central, and southern segments that differ from each others in orientation and style. The anticline is dissected by 18 minor faults of different orientations and sense of displacement. Two perpendicular fracture sets with one being parallel to the anticline axes were recorded in the two anticlines. Both anticlines are interpreted as fault-propagation folds that were formed during the Late Cretaceous first Alpine orogeny. The mid-Late Tertiary second Alpine orogeny and Late Tertiary eastward tilting of the Arabian Plate increased the degree of folding and faulting. (author)

    Full Text Available Background: There is little information on the association between watching Television (TV and obesity in the Arabian Peninsula. Aim of the Study: The aim of this study was to explore the association between the watching of television and obesity in Saudi children of school-age. Materials and Methods: A case-controlled study was conducted with students between the ages of 9 and 14 years who attended the school health clinic in King Abdulaziz Housing for National Guard (Iskan, Riyadh, Saudi Arabia, during the study period (February to April 2012. During each clinic, children were selected by simple random sampling (five obese and five non-obese. For data collection, two trained physicians interviewed the participants using a 20-item Arabic questionnaire. Well-trained nurses collected the anthropometric measurements of weight and height. Results: The study included 397 students. Higher (body mass index BMI was associated with a higher number of televisions at home (P < 0.001, watching TV for more than three hours per day at the weekend (P = 0.047, eating more than three snacks per day (P = 0.005, watching TV at night (P = 0.026, and siblings? decisions on how much TV to watch (P = 0.025. The prevalence of childhood obesity was significantly lower among those whose mothers determined how much TV they could watch (P = 0.03. In logistic regression analysis, the increase in the child?s age, the presence of more than one TV at home, having his or her own TV, and an increase in the number of hours of watching TV over the weekend were significantly associated with an increased risk of childhood obesity. Personal computers and the Internet were not significantly associated with an increased risk of childhood obesity. Conclusion: The present investigation revealed that watching TV represents an important risk factor for obesity in children of school-age.

    Full Text Available E-Government increases transparency and im-proves communication between the government and the users. Providing e-Government services to business sector is a fun-damental mission of governmental agencies in Saudi Arabia. However, the adoption of e-Government systems is less than satisfactory in many countries, particularly in developing coun-tries. This is a significant factor that can lead to e-Government failure and, therefore, to the waste of budget and effort. One pertinent, unanswered question is what are the key factors that influence the adoption and utilisation level of users from business sector. Unlike much research in the literature that has utilised common technology acceptance models and theories to analyse the adoption of e-Government, which may not be sufficient for such analysis, this study proposes a conceptual framework following a holistic approach to analyse key factors that influence the adoption and utilisation of e-Government in Saudi Arabia. The developed framework, E-Government Adoption and Utilisation Model (EGAUM, was developed based on critical evaluation of several common models and theories related to technology acceptance and use including Technology Acceptance Model (TAM and Unified Theory of Acceptance and Use of Technology (UTAUT, in conjunction with analysis of e-Government adoption literature. The study involved 48 participating business entities from two major cities in Saudi Arabia, Riyadh and Jeddah. The descriptive and statistical analyses are presented in this paper and the results indicated that all the proposed factors have degree of influence on the adoption and utilisation level. Perceived Benefits, Awareness, Previous Experience, and Regulations & Policies were found to be the significant factors that are most likely to influence the adoption and usage level of users from business sector.

    BACKGROUND: The role of consanguinity in the etiology of structural birth defects outside of chromosomal and inherited disorders has always been debated. We studied the independent role of consanguinity on birth defects in Saudi women with a high prevalence of consanguineous marriages. METHODS: This case and control study was nested within a 3-year prospective cohort study to examine patterns of fetal and neonatal malformations in Saudi women at Prince Sultan Military Medical City (PSMMC), Riyadh -Saudi Arabia. Consanguineous marriages were defined as marriages with first or second cousins (related); unions beyond second cousins (distant relatives) were considered unrelated for this study. RESULTS: During the 3-year study (July 2010 through June 2013), there were 28,646 total births; of these, we included 1,179 babies with major birth defects, and 1,262 babies as their controls. The consanguinity prevalence for all included women was 49.6%. The consanguinity among babies with major Birth Defects (BDs) was 54.5% and 45.2% for controls (P?

  20. Analysis of a Solar Cooling System for Climatic Conditions of Five Different Cities of Saudi Arabia

    Full Text Available Air high in humidity leads to uncomfortable conditions and promotes the growth of different fungi and bacteria, which may cause health problems. The control of moisture content in the air using traditional air conditioning techniques is not a suitable option due to large consumption of primary energy and hence emission of greenhouse gases. The evaporative cooling technology is a cost effective and eco-friendly alternative but can provide thermal comfort conditions only under low humidity conditions. However, the evaporative cooling method can be used effectively in conjunction with desiccant dehumidifiers for better control of humidity. Such systems can control the temperature and humidity of the air independently and can effectively utilize the low-grade thermal energy resources. In this paper, the theoretical analysis of desiccant based evaporative cooling systems is carried out for five cities in Saudi Arabia (Jeddah, Jazan, Riyadh, Hail, and Dhahran. It has been observed that the coefficient of performance (COP of the system varies from 0.275 to 0.476 for different locations. The water removal capacity of the desiccant wheel is at its maximum for the climatic conditions of Jazan and at its minimum for Hail. The effect of climatic conditions of five cities on regeneration temperature, air mass flow rate, and potential of solar energy has been evaluated using RET Screen software.

    The oocysts of Eimeria biarmicus sp. n. were described from the feces of the lanner falcon, Falco biarmicus, collected from the falcon market in Riyadh City, Saudi Arabia. The prevalence of infection was 5% (2/40). The majority of the oocysts examined had completed sporulation within 84 h at 24 ± 2°C. Sporulated oocysts are ovoid in shape, measuring 22.4 × 17.9 (20.5-24.7 × 15.8-18.5) ?m; shape index (L/W) is 1.25 (1.14-1.36) ?m. The oocyst wall is smooth and bi-layered. Micropyle and oocyst residuum are absent. A polar granule is present, consisting of 2-4 globules. Sporocysts are ovoid, 10.1 × 6.1 (9.4-11.2 × 5.4-6.8) ?m; with a smooth single-layered wall and a minute Stieda body, but there is no substieda body. The sporocyst residuum consists of numerous small granules. Sporozoites are comma shaped, each contains two refractile bodies. E. biarmicus sp. n. is the second eimerian species described from F. biarmicus. PMID:21997853

    Full Text Available This study examines the applicability of theory of reasoned action (TRA in a context of internet banking intention using structural equation modeling (SEM, hence it is intended to test whether the theory is acceptable or not in a newly context among none western culture, thus, emic measures of etic latent constructs are required. The simplified theory is tested using survey data from 350 respondents. Out of these, only 304 questionnaires are found to be usable whilst the rest are omitted owing to the incomplete responses or due to statistical circumstances. Results suggest that Compared to the TRA model, our generating model can create a much better understanding of actual internet banking behavior among Saudi consumers in Riyadh. The results indicated that direct paths from attitude to actual behavior and when adding a path from SN to attitude would improve the predictive power of the model and convincing improvement in fit, more so than what had been established by the original TRA model.

    Full Text Available Abstract Background During an infectious disease outbreak, it is critical to learn as much as possible about the concerns, knowledge, attitudes, and behavior of the public. Such information can be crucial to the improvement of communication efforts by public health officials and clinicians. The aim of this study was to identify awareness, attitudes, and practices related to influenza A (H1N1 among the Saudi public. Methods A cross-sectional study of 1,548 adult subjects recruited from various shopping malls in Riyadh and Jeddah was conducted. All of the subjects were interviewed using a questionnaire that tested their knowledge, attitudes, and use of precautionary measures in relation to the H1N1 influenza pandemic. Results More than half (54.3%, 840/1548 of the participants showed high concern, 43.7%(677/1548 showed a low level of knowledge, and 60.8%(941/1548 had taken minimal or no precautionary measures. After adjusting for other variables, education level was the only significant predictor of the level of concern (p Conclusions High concern did not translate into a higher compliance with precautionary recommendations, possibly due to the low level of knowledge about the disease among the public. Frequent communication between physicians and the public is recommended to help dispel myths about the disease and to spread better information about the role that the public can play in limiting the spread of the disease.

    Full Text Available A mobile learning system, called MobiQiyas, for preparing Saudi Arabian students for one of the standardized tests, given by the National Center for Assessment in Higher Education (NCAHE, has been developed, using ready-made commercial products and tools. The learning material of MobiQiyas consists of practice questions with their answers, both provided by NCAHE, to be loaded by the students into their own mobile phones; after installation, the students can interact with MobiQiyas any number of times, as desired, without incurring any additional cost, other than the initial airtime cost for downloading. From total number of students taken the test, 20,000 students were randomly selected to use MobiQiyas and information was collected from them to measure their attitudes and participation of MobiQiyas. It was found that 36.1% of students had actually downloaded MobiQiyas successfully. Furthermore, a telephone survey was conducted, after the test period, on a class of 40 students in a secondary school in Riyadh, taking the same test, to measure their acceptance of MobiQiyas, using a 9-item questionnaire based on a 5-point Likert scale. The responses of the 40 students reflected high acceptance and satisfaction levels of MobiQiyas as an effective test prep tool.

    Full Text Available Objectives: To determine whether 12-month, 2000IU/day vitamin D supplementation cardiometabolically improves treatment naïve type 2 diabetes mellitus (T2DM Saudi patients with vitamin D deficiency. Methods: This 12-month interventional study was conducted at primary health centers in 5 different residential areas in Riyadh, Saudi Arabia between January 2013 and January 2014. Forty-five Saudi T2DM patients were enrolled. Baseline anthropometrics, glycemic, and lipid profiles were measured and repeated after 6 and 12 months. All subjects were provided with 2000IU vitamin D supplements for one year. Results: Vitamin D deficiency at baseline was 46.7%, 31.8% after 6 months, and 35.6% after 12 months, indicating an overall improvement in the vitamin D status in the entire cohort. Insulin and homeostatic model assessment-insulin resistance (HOMA-IR after 12 months were significantly lower than a 6 months (p<0.05, but comparable to baseline values. Mean levels of triglycerides increased overtime from baseline (1.9±0.01 mmol/l to 12 months (2.1±0.2 mmol. This modest increase in serum triglycerides was parallel to the insignificant decrease in circulating high-density lipoprotein -cholesterol levels. Conclusion: Twelve-month vitamin D supplementation of 2000IU per day in a cohort of treatment naïve Saudi patients with T2DM resulted in improvement of several cardiometabolic parameters including systolic blood pressure, insulin, and HOMA-IR. Further studies that include a placebo group are suggested to reinforce findings.

  7. Perceived stress among male medical students in Egypt and Saudi Arabia : Effect of sociodemographic factors

    International Nuclear Information System (INIS)

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

    Bovine ephemeral fever virus (BEFV) is an arthropod-borne rhabdovirus that causes disabling clinical signs and major economic losses in cattle and water buffalo. The disease is well documented in Asia, Africa, and the Middle East; however, the seroprevalence of BEFV in different regions and bovine breeds in the Kingdom of Saudi Arabia (KSA) is unknown. The aim of this study was to analyze risk factors which affect the prevalence of antibodies against BEFV in small herds of cattle in four geographical regions of KSA. A total of 1480 serum samples from non-BEFV vaccinated small herds of cattle were collected from the Eastern, Jizan, Qasim, and Riyadh regions (370 samples per region) during the summer of 2010. Serum neutralization test was used to detect antibodies against BEFV. There was a significant effect of region, breed, sex, and age on the seroprevalence of BEFV. Seropositive ratios were 18, 18, 26, and 12 % for the Eastern, Jizan, Qasim, and Riyadh regions, respectively (P?=?0.00002); 23.2 % for dairy and 13.7 % for non-dairy breeds (P?=?0.00004); 24.4 % for males and 14.6 % for females (P?=?0.00004); and 15.4, 29.1, and 11.4 % for animals 3 years, respectively (P?

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

    Full Text Available Few studies have addressed racial differences in prostate cancer (PCa) detection between Western and Arabian countries, although PCa has a significantly lower prevalence in Arabic populations compared to Western populations. Therefore, an explanation of this difference is lacking. Ser [...] um prostate-specific antigen (PSA) is a valuable marker used to select patients who should undergo prostate biopsies, although the manner in which it is used may require adjustments based on the ethnic population in question. We investigated racial differences in the PCa detection rate between Canadian and Saudi populations. A retrospective analysis was performed of data collected prospectively over 5 consecutive years in urology clinics at the McGill University Health Center (MUHC) and King Saud University Hospital (KSUH). Men who had high (>4'ng/mL) or rising PSA levels and a negative digital rectal examination were eligible. A total of 1403 Canadian and 414 Saudi patients were evaluated for the study; 717 and 158 men, median age 64 and 68 years, were included in the MUHC and KSUH cohorts, respectively, P

Descriptive statistics were used to report the results.Results: The responses indicated inadequate health-related practices in the surveyed group: 22.2% brushed their teeth twice daily, 73.6% never flossed their teeth, and while 80.2% visited a physician in the past year, only 12.6% visited a dentist during the same year. Of the respondents, 94.8% reported that they had never received advice on oral hygiene tasks in relation to diabetes from a health professional. Awareness about the diabetes and periodontal disease association was limited: 46.7% knew that diabetics have gum problems more often if their blood sugar stays very high, and only 21.8% knew that gum disease makes it harder to control blood sugar in diabetic patients. A significant association (P<0.05 was found between a higher level of education and greater general and oral awareness, as well as a significant association (P<0.05 between longer duration of disease, regular exercise, and regular visits to the physician and awareness about diabetes mellitus. Additionally, a significant association (P<0.05 was found between regular dental visits and both periodontal disease and diabetes awareness. Family and friends were the main source of diabetes-related information, and the Internet was the least likely source.Conclusion: Customized educational programs should be planned for diabetic patients according to community needs.Keywords: periodontal health, diabetes, patients, awareness, Saudi Arabia

  5. Disinfection of wastewater from a Riyadh Wastewater Treatment Plant with ionizing radiation

    International Nuclear Information System (INIS)

    The goal of this research was to establish the applicability of the electron beam treatment process for treating wastewater intended for reuse. The objective of this study was to determine the effectiveness of gamma irradiation in the disinfection of wastewater, and the improvement of the water quality by determining the changes in organic matter as indicated by the measurement of biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total organic carbon (TOC). Samples of effluent, before and after chlorination, and sludge were obtained from a Riyadh Wastewater Treatment Plant. The studies were conducted using a laboratory scale 60Co gamma source. The improvement in quality of the irradiated samples was demonstrated by the reduction in bacteria, and the reduction in the BOD, COD and TOC. Radiation of the wastewater provided adequate disinfection while at the same time increasing the water quality. This treatment could lead to additional opportunities for the reuse of this valuable resource. Limited studies, conducted on the anaerobically digested secondary biosolids, showed an improvement in bacterial content and no change in COD

    Objectives: To review and analyze the pattern of breast cancer (BC) in the Kingdom of Saudi Arabia (KSA). Methods: A retrospective descriptive epidemiological review of BC of all diagnosed Saudi female cases from January 1990 to December 2014 was conducted at the Faculty of Sciences, Department of Biology, University of Tabuk, Tabuk, KSA. This report contains information obtained from the Saudi Cancer Registry and from King Faisal Specialist Hospital and Research Center. Results: The number of women with BC increased steadily from 1990-2010. On the basis of the number of cases, the percentage distribution of BC appears to be increasing. There were 1152 female BC cases in 2008 in comparison with 1308 in 2009, and 1473 in 2010. Breast cancer ranked first among females accounting for 27.4% of all newly diagnosed female cancers (5378) in the year 2010. The average age at the diagnosis of BC was 48; weighted average was 49.8, and range 43-52. Conclusion: Among Saudi patients, there was a significant increase in the number of cases of BC, which occurs at an earlier age than in Western countries. Continued vigilance, mammographic screening, and patient education are needed to establish early diagnosis and perform optimal treatment. PMID:26446327

    2009-02-01

    Full Text Available Control Objectives for Information and Related Technology (COBIT has become one of the most important guidelines for information technology governance (ITG, which provides organizations with a useful tool to start evaluating their own ITG systems. COBIT introduces an ITG framework and supporting toolset that allows IT managers to bridge the gap between control requirements, technical issues and business risks. The objective of this study is to investigate the formality, auditing, responsibility and accountability of implementing COBIT processes for ITG in Saudi organizations. An empirical survey, using a self-administered questionnaire, was conducted to achieve these objectives. Five hundred questionnaires were distributed to a sample of Saudi organizations in a selected number of Saudi cities. One hundred and twenty seven valid questionnaires – representing a 25.4 percent response rate –were collected and analyzed using the Statistical Package for Social Sciences (SPSS version 16. While the results of the study reveal that the majority of respondents reported that implementing ITG COBIT processes and domains is the responsibility of IT departments in Saudi organizations, most of the respondents reported that the COBIT processes and domains are neither audited nor formally conducted in their organizations. From a practical standpoint, managers and practitioners alike stand to gain from the findings of this study. The study provides useful information for senior management, IT managers, accountants, auditors, and academics to understand the implementation phase and the impact ofCOBIT on ITG in Saudi organizations.

    AIM To describe the clinical features, systemic associations, treatment and visual outcomes in Saudi patients with scleritis. METHODS A retrospective chart review was performed for patients with scleritis presenting to two tertiary care eye hospitals in Riyadh, Saudi Arabia, from 2001 to 2011. Data were collected on the clinical features of scleritis, subtypes of scleritis, associated systemic disease, history of previous ocular surgery and medical therapy, including the use of immunosuppressants. Treatment outcomes were evaluated based on best-corrected visual acuity (BCVA) and response to treatment. RESULTS Of the 52 patients included in the study, non-necrotizing anterior scleritis was the most common type of scleritis in 22 patients (42.3%), followed by posterior scleritis in 14 patients (26.9%). The majority of cases, 31 patients (59.6%), were idiopathic in nature. Systemic associations were present in 12 patients (23.1%). Infectious scleritis was confirmed in 6 patients (11.5%): 3 with bacterial scleritis after pterygium excision, 2 patients with scleritis related to tuberculosis and 1 patient with scleritis resulting from herpes simplex infection. For the various subtypes of scleritis, BCVA values after treatment and time to remission significantly differed (P<0.05, all cases). Systemic immunosuppressive therapies in addition to steroids were administered to 46.2% of all patients. The T-sign was present on B-scan ultrasonography in 9 (64.3%) of the 14 posterior scleritis patients. CONCLUSION Non-necrotizing anterior scleritis was the most common subtype of scleritis. Final visual outcome and time to remission differed among the various scleritis subtypes. PMID:26682176

    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.

  18. The knowledge of breast cancer among young Saudi females

    International Nuclear Information System (INIS)

    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).

    The subject-matter is intriguing as Saudi Arabia is perceived as the incarnation of Islam. In fact, it has no constitution since the Quran is regarded as its constitution. Moreover, Islam was instrumental in its state building. But Dr. Lacroix is, after his field work, well-placed to discuss the issue. His talk is based on his Ph.D from Paris, his French book and its English edition that is to be published soon by Harvard University Press.

    Full Text Available Background: The satisfaction of surgical residents with their training programs plays an important role in dictating its output. This survey was conducted to explore the satisfaction of surgical residents with their training programs in the Riyadh area. Methods: A survey questionnaire was distributed in four major hospitals to explore the view of surgical residents regarding their training programs. Frequency tables were generated for each question in the survey. Results: About 78 survey forms were distributed and 52 were retrieved (67%. About 45% of residents had a comprehensive orientation on admission to the program, but only 20% felt it was helpful. Only 40% of residents felt that their trainers were committed to training and that the consultants who were trained abroad were more committed than those trained locally (62% vs 36%, P =.01. Only 15% felt the residents themselves had enough bedside teaching or operative experience. Seventy-eight percent of the residents felt that current training does not meet their expectations. However, 85% felt that training abroad was better than local training, and 60% felt it should be mandatory. While 90% felt that training programs should be unified nationally and controlled by one organization, only 6% felt that the current governing body was capable of monitoring the training. Moreover, only 28% felt that current reviews of programs by the governing body are effective. Conclusions: These results show that surgical residents are generally dissatisfied with current training programs. The study suggests that there are significant weaknesses in the current programs and the governing body may be ineffective in monitoring the programs. We feel that a national review of surgical training programs is warranted in view of these results.

    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.

  18. Asthma control assessment using asthma control test among patients attending 5 tertiary care hospitals in Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was the evaluation of asthma control using the Asthma Control Test (ACT). The ACT was used to assess asthma control among patients with bronchial asthma visiting pulmonary clinics in 5 major tertiary care hospitals in Riyadh, Kingdom of Saudi Arabia. Each hospital had target of 300 patients to recruit over the period of the study from 1st September to 30th November 2006. The total number of patients studied was 1060 patients. Males constituted 442 (42%) and the females constituted 618 (58%), the median age was 38.56 years range 15-75. One-third of the patients had no formal education. The ACT score revealed uncontrolled asthma in 677 (64%), well controlled asthma in 328 (31%) and complete controlled in 55 (5%). There were no significant correlation between the age below 40 and above 40 years and level of asthma control p=0.12. However, the younger age group less than 20 had better control of asthma in comparison with older patients p=0.0001. There was significant correlation between level of asthma control and gender, males 44% had better asthma control than females (30%, p=0.0001). Control of bronchial asthma is still major concern in our population. Further studies are needed to explore the factors leading to poor asthma control. (author)

    Adolescence is known to be a time of exploration and initiation of risky behaviors. Much attention has been given to risk behaviors such as smoking, violence, and sexual promiscuity; other serious behaviors such as self-strangulation or the choking game, which is carried out by adolescents in response to peer pressures or to gain a transient sense of euphoria, have received little attention, with the available literature coming from the developed world. This is the first report of cases of non-suicidal self-strangulation from the Arab World. In this case series, we report 5 cases of non-suicidal self-strangulation that presented to the Emergency Department of a tertiary care hospital in Riyadh, Saudi Arabia during 2010-2012. All of the 5 cases were young male adolescents aged 10-13 years. This activity resulted in the death of 2 boys; one boy sustained hypoxic ischemic insult to the brain with clinical deficits; and the remaining 2 were fortunate to be discharged home in healthy condition. None of the cases had underlying mental health problems, and multidisciplinary involvement ruled out suicide and homicide activities. Non-suicidal self-strangulation is a fatal behavior that adolescents engage in. Increased efforts are needed to address this serious and preventable public health issue. Awareness and education of adolescents and their parents is crucial. Awareness of healthcare providers is also necessary in order to avoid misdiagnosis of such cases. PMID:25623195

    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.

  1. NMR used for Saudi crude asphaltenes

    International Nuclear Information System (INIS)

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

  2. Seawater can damage Saudi sandstone oil reservoirs

    Energy Technology Data Exchange (ETDEWEB)

    1990-12-10

    Experiments have shown that formation damage from waterflooding of the Aramco and Alkhafji sandstones of Saudi Arabia will not occur if the salinity of the injected brines is higher than 20% NaCl. Because the connate water in these reservoirs has a high salt content of up to 231,000 ppm, Saudi oil fields are almost always susceptible to formation damage when flooded with seawater (about 38,500 ppm). The productive behavior of a reservoir can be affected by clay crystals developed within rock pores.

  3. Extremely elevated erythrocyte sedimentation rate. Etiology at a tertiary care center in Saudi Arabia

    International Nuclear Information System (INIS)

    To evaluate the etiology of extremely elevated erythrocyte sedimentation rate (ESR) in adolescents and adults at a tertiary care center. This retrospective, cross-sectional, observational study was carried out at King Abdulaziz Medical City, Riyadh, Saudi Arabia using the Westergren method of determining ESR in adolescents and adults aged >/=12 years. The patients included inpatients and outpatients with medical, surgical, and gynecological problems. During a period from June 2007 to October 2008, consecutive, non-repetitive patients with ESR >/=100 mm/hour were evaluated for possible etiology by checking the electronic and paper data file of each patient. During the study period, out of the 44,366 ESR tests carried out at this center, 1864 (4.2%) had an ESR >/=100 mm/hour belonging to 567 patients. Out of 508 patients fulfilling the study criteria, the main associated causes included: infections (38.6%), autoimmune diseases (15.9%), malignancy (15.4%), miscellaneous causes (10.2%), ischemic tissue injury or trauma (8.7%), and renal diseases (8.4%). Ten common individual causes included: rheumatoid arthritis (7.3%), osteomyelitis (6.9%), tuberculosis (5.5%), trauma (5.3%), lymphoma and sepsis of unknown origin (5.1%) each, urinary tract infection (4.7%), septic arthritis (3.1%), abscesses (2.8%), and pregnancy (2.2%). Fourteen (2.4%) patients had no known cause. Most of the patients with extreme ESR elevation have an underlying cause and a focused evaluation of such patients needs to be carried out to reach a diagnosis.

  4. Cerebral venous thrombosis in Saudi Arabia. Clinical variables, response to treatment, and outcome

    International Nuclear Information System (INIS)

    To investigate cerebral venous thrombosis (CVTR) clinical presentations, risk factors, and response to treatment in Saudi Arabia. Retrospective analysis of the King Farad Medical City, Riyadh, acute stroke database from April 2005 through February 2008 revealed 22 patients with CVTR. Hyper coagulable work-up and neuroimaging were performed. Sixteen patients were female (72.7%), and the median age was 35 years. Clinical presentations included: headache (77.3%), seizures (54.5%), focal neurological signs (54.5%), and decreased level of consciousness (50%). Over two-thirds (n=11; 69%) of female patients had a history of oral contraceptive use, which was the most common risk factor. Protein S deficiency (n=3), anti phospholipid antibody syndrome secondary to systemic lupus erythematosus (SLE) (n=1), rhinocerebral mucormycosis (n=1), leukemia (n=1), non-Hodgkin's lymphoma (n=1), sepsis (n=1), and unknown (n=6) were causes. Affected areas included superior sagittal (n=13), transverse (n=16), sigmoid (n=14), straight (n=6), and cavernous sinus (n=1); internal cerebral vein (n=2); vein of Galen (n=3); cortical veins (n=10); and internal jugular vein (n=12). Two patients had quadriparesis, and 2 patients died. The remainder (n=18, 81.8%) improved. Bilateral hemorrhagic presentation or venous infarction, deep venous system thrombosis, and underlying malignancy had less favorable results. Presentations in our series were similar to those in other reports, although altered consciousness and seizures were more common. Cortical vein involvement was also higher than commonly reported. Oral contraceptive use was a primary risk factor in female patients. Outcomes were favorable in 81.8% of patients. (author)

    Full Text Available The purpose of this study was to investigate serological prevalence and titers of anti-Toxoplasma gondii antibodies in ewes following waves of abortion and stillbirths in a commercial flock in Riyadh, Saudi Arabia. Serum samples from 168 aborted ewes and 52 breeding rams, were tested for toxoplasmosis using an indirect enzyme-linked-immunosorbent assay (ELISA and indirect haemagglutination test (IHA. 71 randomly sampled sheep from an abortion-free flock (60 ewes and 11 rams were also tested, which served as controls. 149 (88.7% ewes and 42 (80.8% breeding rams from the flock where abortions and stillbirths occurred were positive for anti-T. gondii antibodies by ELISA. 155 ewes (92.3% and 44 rams (84.6%, including all of the ELISA positive cases, were also positive by indirect haemagglutination test (IHA. More than 80% of the ELISA positive ewes had O.D. exceeding 100% and nearly 25% of them had O.D. of ≥150%. The IHA results, on the other hand, indicated that more than 75% of the seropositive ewes had antibody titers ≥1:1024, including 58 (37.4% ewes with IHA titer ranging between 1:4096-1:8192 Pyrexia, depression and vaginal discharge were recorded in some ewes shortly prior to abortion. Post-mortem examination of 5 aborted fetuses revealed blood-stained fluid in the abdominal and thoracic cavities and small inflammatory and necrotic foci in the brain, liver and lungs while the placenta was reddish and friable, and its cotyledons were speckled with small whitish foci of necrosis and mineralization. T. gondii tachyzoites were demonstrated in placental sections of two ewes. By contrast, only 7 (9.9% out of 71 randomly sampled sheep from an abortion-free flock (60 ewes and 11 rams, were positive for anti-T. gondii antibodies by ELISA and 6 (8.5% by indirect haemagglutination (IHA test and most of these had significantly lower titers compared to the flock where abortions and stillbirths were recorded. These results constitute the first detailed serological study of ovine toxoplasmosis in Saudi Arabia and strongly implicate toxoplasmosis as the cause of the abortions and stillbirths in these sheep.

  8. Saudi experience with classic homocystinuria

    International Nuclear Information System (INIS)

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

    Althagafi, A.; Richardson, M.

    2015-03-01

    This paper focuses on the use of the Yuri Nikolaevich DENISYUK holographic recording process to document, archive and display Saudi heritage. The goal of this research is to develop a technique of archiving heritage by using a high-tech holographic process to capture a three-dimensional presentation of ancient jewelry artifacts of the Saudi Heritage in particular. This study concentrates on five particular items of handmade authentic ancient metal jewelry from different parts of Saudi Arabia. When conducting this research experiments were conducted using both red-green sensitive plates sensitive to 633 nm and 532 nm respectively. Material thickness ranged between 1.5 and 3 millimeters were used, consequently in the dark room, varied chemicals for developing the holograms were employed. Red and green laser devices were also used with exposure times between 8 to 18 seconds of laser light dispersion through diffused surfaces in reflection holography. The outcome in each case was varied. The holograms captured the jewelry pieces with all the engravings and minute details, thus archiving the Saudi Heritage of that time. What makes holograms a revolutionary method for presenting valuable and/or ancient artifacts is the fact that they offer a more practical and convenient solution to travel around the world than displaying the originals items. Thus, museum visitors can enjoy and appreciate the precious artifacts otherwise unseen and lost without holography.

  12. Implementation of nuclear desalination in Saudi Arabia

    International Nuclear Information System (INIS)

    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)

  14. Career profile of dentists in Saudi Arabia

    International Nuclear Information System (INIS)

    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.

    This article aims to increase an awareness of caring for Saudi families by non-Saudi nurses to improve their understanding of culturally competent care from a Saudi perspective. Healthcare providers have a duty of a care to deliver holistic and culturally specific health care to their patients. As a consequence of 'duty of care' obligations, healthcare providers must facilitate culturally congruent care for patients of diverse cultural backgrounds. For the Saudi family considerable cultural clashes may arise when Saudi patients are hospitalized and receive care from healthcare professionals who do not understand Islamic principles and Saudi cultural beliefs and values. The healthcare workforce in Saudi Arabia is a unique multicultural workforce that is mix of Saudi and significant other nationalities. Saudi nurses for example represent only 36.3% of the workforce in the different health sectors. Whilst the different ethnic and cultural background expatriate nurses represent 63.7% (Ministry of Health, 2010). This article also could increase the awareness of healthcare professionals caring for Arab and Muslims patients in another context in the world. PMID:24787260

    The Dahl Hith cave is located approximately 30 km southeast of Riyadh, the capital of Saudi Arabia. In the past decades, the groundwater table exposed inside the cave became subject to appreciable changes. After a decline due to agricultural water abstraction for irrigation purposes, the water table exhibited a rapid rise in the last few years. Considering that most of the aquifers of the country show a depletion of the largely fossil groundwater, the mentioned rise is quite unusual. The area does not host an observation well, i.e., reliable data on the piezometric changes is hitherto not available. Hence, two uncommon data sources were used to reconstruct the water level changes: (1) YouTube videos and (2) graffiti inscriptions. (1) The cave is frequently visited by locals and expats from Riyadh and many visitors are willing to share their cave adventures on YouTube. Identifying certain reference points in the uploaded videos (e.g. specific boulders, cave graffiti) and estimating their position relative to the water table allows for an approximate reconstruction of the recent groundwater rise. Information on the observation time is derived from the uploading date. Occasionally, also the exact date of the visit is provided as part of the footage description. (2) Some people documented their visit by graffiti inscriptions. These do not only serve as a marker in the videos, but also contain genuine data on historic water levels: if written on parts of the cave wall, which are only accessible from the water, they indicate the water level at the time of their creation. Fortunately, some graffiti also feature the date of the visit. In order to improve the reliability of the water level estimations, measurements conducted in the course of own site visits in the past few years were considered for the evaluation. Also photographs taken during these surveys helped to improve the quality of the water level reconstruction. The described "Youtube Approach" could be interpreted as a citizen science project with citizens being unaware of their participation. It illustrates the occasional need for creative solutions in data-scarce settings.

    On 10th March 2009 a widespread and severe dust storm event that lasted several hours struck Riyadh, and represented one of the most intense dust storms experienced in Saudi Arabia in the last two decades. This short-lived storm caused widespread and heavy dust deposition, zero visibility and total airport shutdown, as well as extensive damage to buildings, vehicles, power poles and trees across the city of Riyadh. Changes in Meteorological parameters, aerosol optical depth (AOD), Angstrom exponent ?, infrared (IR) sky temperature and atmospheric emissivity were investigated before, during, and after the storm. The analysis showed significant changes in all of the above parameters due to this event. Shortly after the storm arrived, air pressure rapidly increased by 4 hPa, temperature decreased by 6 °C, relative humidly increased from 10% to 30%, the wind direction became northerly and the wind speed increased to a maximum of 30 m s -1. AOD at 550 nm increased from 0.396 to 1.71. The Angstrom exponent ? rapidly decreased from 0.192 to -0.078. The mean AOD at 550 nm on the day of the storm was 0.953 higher than during the previous clear day, while ? was -0.049 in comparison with 0.323 during the previous day. Theoretical simulations using SMART software showed remarkable changes in both spectral and broadband solar radiation components. The global and direct radiation components decreased by 42% and 68%, respectively, and the diffuse components increased by 44% in comparison with the previous clear day. IR sky temperatures and sky emissivity increased by 24 °C and 0.3, respectively, 2 h after the arrival of the storm. The effect of aerosol loading by the storm on IR atmospheric emission was investigated using MODTRAN software. It was found that the effect of aerosols caused an increase of the atmospheric emission in the atmospheric window (8-14 ?m) such that the window emissions resembled those of a blackbody and the atmospheric window was almost closed.

    Purpose This study aimed to examine diabetic patients in Jeddah, Saudi Arabia, regarding their general diabetic and oral health-related awareness and practices, their awareness of the association of diabetes with periodontal disease, and their sources of diabetes-related information. Methods Diabetic patients (n=454) who were receiving care at the diabetes clinic in King Abdulaziz University Hospital, Jeddah, Saudi Arabia, from October 2013 to May 2014, completed a six-part questionnaire assessing their sociodemographic characteristics, general and oral health awareness and practices, and sources of diabetes-related information. 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 (Pdental visits and both periodontal disease and diabetes awareness. Family and friends were the main source of diabetes-related information, and the Internet was the least likely source. Conclusion Customized educational programs should be planned for diabetic patients according to community needs. PMID:25673974

  7. Saudi Aramco describes crisis oil flow hike

    International Nuclear Information System (INIS)

    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)

  8. Peaceful nuclear energy to Saudi Arabia

    International Nuclear Information System (INIS)

    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.)

    Full Text Available 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. Hence a gap in the literature that examines Middle Eastern countries exists. This study is motivated to fill such gap by going beyond case study and boundaries of Western counties to empirically examine the determinants of successful ERP implementation in Saudi Arabia. The main purpose of this study is to examine the influence of some critical factors on successful implementation of ERP.

    The relation between birthweight and parity of the mother was examined in Saudi patients from Tabuk and Najran. 4,664 newborns were taken into consideration from 1985-1988. 30.7% (1,430) of these newborns were born to mothers with more than 5 deliveries. A positive correlation between the increasing number of the parity and the birthweight can be demonstrated in our patients from parity 9. From parity 9 to parity 11 there is an increasing birth-weight of the male newborns, whereas the weight of the female newborns shows different tendencies. The average age of a Saudi primipara is 20.5 years and increases by 1.05-1.99 years until parity 11. From parity 11 to parity 13 it increases by 0.7 years. PMID:2402965

  11. Core inflation indicators for Saudi Arabia

    2015-01-01

    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.

  12. Operators in Yemen draw warning from Saudis

    International Nuclear Information System (INIS)

    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

    Skin lipids play an important role in the regulation of cutaneous water loss (CWL). Earlier studies have shown that Saudi desert birds exhibit a tendency of reduced CWL than birds from temperate environment due to adaptive changes in composition of their skin lipids. In this study, we used thin-layer chromatography (TLC) for separation and detection of non-polar and polar lipids from the skin of six bird species including sooty gull, brown booby, house sparrow, Arabian waxbill, sand partridge...

    The Aedes Meigen (Diptera: Culicidae) mosquito species populations in the western region of Saudi Arabia, especially in and around Jeddah, are increasing, therefore increasing susceptibility of humans to the dengue virus. An extensive survey was carried out for one year, and four species were identified with the help of different pictorial keys available. The identification was based on morphological characteristics of adult female Aedes mosquitoes.

    A total of 1016 healthy Saudi mothers and their respective infants (aged 3-12 months) were recruited from 57 Primary Health Care Centers (PHCCs) in Riyadh, Saudi Arabia, to evaluate the extent of mercury (Hg) exposure and predict its sources in the healthy Saudi population. Total Hg levels were measured in maternal urine, breast milk, blood, and hair and in the infants' urine and hair. Only 1.9% of the mothers had urinary Hg (UHg)>10 ?g/l, the limit for asymptomatic adults recommended by the World Health Organization, but the median (0.99 ?g/l) was higher than in other countries. Also, 49.3% of the mothers had UHg>1 ?g/l, the German reference value for adults. Median infant UHg was 0.729 ?g/l, and 77 and 93 % of the infants had levels higher than 0.4 and 0.1 ?g/l, the reference values of the Centers for Disease Control and Prevention and for Germany, respectively. The median Hg level in breast milk was 0.884 ?g/l. Even though 43.2% of the milk samples were above the background level for Hg in human milk (1 ?g/l), our results were lower than those reported from other countries. Median maternal total Hg in blood was 0.637 ?g/l, and only 0.4 and 6.9% of samples were higher than the Hg reference levels of 5.8 ?g/l of the Environmental Protection Agency (EPA) and of 2 ?g/l for Germany, respectively. Total Hg levels in hair (HHg) varied widely among mothers and infants, but only 3.9% of the mothers and 2.8% of the infants had HHg>1 ?g/g (the EPA reference level). Median HHg values were 0.117 ?g/g dry weight in mothers and 0.1 ?g/g dry weight in infants; both were lower than in other countries. The Hg levels in mothers and their respective infants were relatively low, but our results were consistent with other studies indicating that dental amalgam fillings and fish consumption were the main predictors of maternal Hg exposure. Among the several biomarkers of Hg exposure, Hg levels in maternal hair and urine were the strongest predictors of infant exposure. The lack of an association between Hg in breast milk and Hg in infant urine and hair suggested that the infants were exposed to Hg predominately during pregnancy rather than during breastfeeding. We expect that our data can serve as a baseline for further biomonitoring and follow-up studies, particularly of the long-term impact of Hg on childhood neurodevelopment. PMID:26450688

    Full Text Available Background : Vitiligo has a devastating psychosocial effect. The cultural traditions of Saudi society are quite different compared with the western world. Hence, a quality of life study using a different questionnaire suitable to the cultural traditions of the society is necessary to measure qualify of life in vitiligo patients. Objective : This study was conducted to assess the quality of life (QOL in Saudi vitiligo patients and their family. Materials and Methods : A prospective cross-sectional study at National Center for Vitiligo and Psoriasis, Saudi Arabia. A validated Arabic questionnaire of 41 questions was developed and utilized specifically for this study. Arabic language instrument was distributed to 260 vitiligo patients. Scores were compared in relation to demographic, clinical, and social variables in 4 dimensions of scale (relationship with colleagues, family relationship, social relationship, and self respect. Results : Overall score QOL was 17.1. Mean score for males was 11.1, whereas that for females was 23.9 (P < 0.05. Females scored significantly higher in all the 4 dimensions. Patients with exposed disease lesions scored significantly higher than those with unexposed lesions 5 vs 3.4 (P < 0.05. Conclusion : The overall score of QOL in vitiligo is relatively high, indicating a negative impact of the disease on QOL. QOL in women is significantly more affected than in men.

    The media-fuelled obsession with beauty in modern society has led more women to seek elective cosmetic procedures to meet the portrayed ideals of beauty in different cultures. This study gives insights into incentives and desires to undergo cosmetic procedures in a conservative society with strict religious practices where women are veiled. Questionnaire data were obtained from 509 Saudi women who responded to a survey distributed randomly to a sample of Saudi women aged 17 to 72 years. At least 1 elective cosmetic procedure was performed in 42% of the women, of whom 77.8% wore a veil. Another 33% considered having a procedure. The motives for seeking a cosmetic procedure were to improve self-esteem in 83.7%, attract a husband in 63.3%, or prevent a husband from seeking another wife in 36.2%. The decision to seek a procedure was affected by the media, with high peer influence. Motivation for elective cosmetic procedures in Saudi women is influenced by a combination of emotional and cultural factors, level of education, marital status, and religious beliefs. The veil is not an impediment for seeking such procedures. The limitation of the study was missing data analysis as some items in the questionnaire were completed inaccurately or left unanswered.
