Radon Awareness among Saudi People in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

Perceptions and Attitudes of Riyadh University Students towards Products Derived from Genetically Modified Crops in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available A survey was conducted during 2008 to assess the attitudes and perceptions of the Riyadh University students towards genetically modified crops and foods. Using descriptive analysis, it was found that the majority of surveyed students had good knowledge of genetic modifications, but lack knowledge about Genetically Modified Organisms (GMO values. Most respondents would not purchase clearly labelled GMO products, though considerable number of the respondents was ready to taste or try the products. It is evident from these results that majority of university students who participated in this survey, in general had very little information or didn’t know the genetic engineering technology e.g., gene therapy, fingerprinting, role in reducing pesticide application etc., as appeared in the results, therefore, most of the participants did not know or thought GM foods are harmful and could not be easily detected. The implication of this result is that majority will not support GM products.

CD4+ T-Lymphopenia in HIV negative tuberculous patients at king khalid university hospital in riyadh, saudi arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Tuberculosis (Tb is a chronic infectious disease in which the cellular immunity (specifically CD4+ and CD8 lymphocytes provides the most important defense in controlling infection. CD4 lymphopenia is a well-defined risk factor for the development of active tuberculosis in patients infected with Human Immunodeficiency Virus. In HIV - negative patients, CD4 and CD8 cell count suppression has been associated with Tb infection. Our study was designed to deter mine the baseline and post-treatment values of CD4 and CD8 in HIV negative patients diagnosed with active Tb in Saudi Arabian patients. We recruited twentyeight, non-HIV patients with tuberculosis for the study group comprising 16 males and 12 females with either disseminated or localized active Tb infection. Two control groups were selected - one of twenty one matched healthy controls and the second of fortytwo subjects from pool of controls of an ongoing study in same population for normal CD4 and CD8 counts. The baseline pre-treatment CD4 and CD8 counts in the study group were significantly lower than either control group. Specifically the mean ± SD of CD4 counts were 556.79 ± 298.81 in the study group vs 1,132.38 ± 259.90 in control group 1 and 1,424.38 ± 870.98 in control group 2 (p 0.000. Likewise the CD8 counts in the study group were 1,136.00 ± 512.06 vs. 1,461.90 ± 367.02 in control group 1 and 1,495.90 ± 565.32 in control group 2 (p 0.000 respectively. After treatment of tuberculosis, the study patients experienced a significant increase in their mean ± SD CD4 and CD8 cell counts, from 556.79 ± 297.81 to 954.29 ± 210.90 for CD4 cells (p 0.005 and 1136.00 ± 512.06 to 1,316.54 ± 286.17 for CD8 cells (p 0.002. Analysis of study patients with disseminated disease found significantly lower CD4 cells (but not lower CD8 cells compared to study patients with localized disease, both at baseline and after treatment. The mean ± SD baseline CD4 cells were 247.60 ± 187.80 with disseminated vs 728.56 ± 186.32 for localized disease (p = 0.000 which rose to 842.30 ± 93.55 vs 1016.50 ± 233.51 (p = 0.033 respectively. We conclude that tuberculosis may be associated with CD4 and CD8 lymphopenia even in patients without human immunodeficiency virus infection, there was the tendency of recovery towards normality especially of the CD4 and CD8 counts after treatment, and that disseminated disease is associated specifically with profound CD4 lymphopenia.

Prevalence of tobacco use and exposure to environmental tobacco smoke among saudi medical students in riyadh, saudi arabia.  

Science.gov (United States)

This study was designed to determine the prevalence of active smoking and environmental tobacco smoke (ETS) exposure among medical students in Riyadh, Saudi Arabia, and to examine their attitudes and beliefs towards tobacco control programs. The investigation was a cross-sectional study conducted during the first semester of 2013 at King Saud University School of Medicine located in Riyadh, Saudi Arabia. Invited to participate in this study were 1,789 medical students. A descriptive data analysis was performed. A total of 805 medical students completed the questionnaire. The prevalence of experimentation with cigarette smoking was 11.3 %. The estimated prevalence of current smoking among the study participants was 4.7 %. The majority of the students held positive attitudes toward tobacco control and approximately 93.1 % of the students felt that health care professionals should be required to receive training for cessation counseling while only 36.8 % of the students reported having received any training in this area. Over the study's duration 57.7 % of participants reported that ETS exposure was much higher in public places, while 13.9 % reported exposure at home. This investigation revealed that ETS exposure among medical students in Riyadh is at an alarmingly high rate. The data suggests a need for a more robust smoke-free policy and a commitment to greater enforcement in public places. The results of the study also demonstrate a positive attitude among participants for tobacco control. It also indicates a need for cessation counseling and training which could be incorporated into medical school curriculum. PMID:24903238

Anemia and Iron Intake of Adult Saudis in Riyadh City-Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this study was to evaluate iron deficiency anemia among adult healthy Saudi males and adult healthy non-pregnant Saudi females in Riyadh City, Saudi Arabia. 234 healthy adults were recruited of which, 102 were females and 132 were males. Male subjects were reclassified to cigarette smokers (n = 52 and non-smokers (n = 80. Anemia was assessed by dietary iron intake, hemoglobin and hematocrit levels. Iron intake was measured by analyzing the intake of three consecutive days. The results showed that iron intake, hemoglobin and hematocrit levels were significantly higher in males compared to females. Mean iron intake of males (13.6±3.1 mg/day was adequate compared to DRI recommendation. Mean concentrations of hemoglobin (15.89±0.95 g/dL and hematocrit (47.7±3.6% for males were normal. Hemoglobin and hematocrit levels were significantly higher in smokers compared to non-smokers, but both were normal, which suggested that iron deficiency anemia is not found among adult Saudi males. Mean iron intake of females (10.2±2.8 mg/day was inadequate compared to DRI recommendation. Mean hemoglobin level (13.68±0.83 g/gL and mean hematocrit level (38.9±3.2% of females were lower than cutoff values for determining iron deficiency anemia. Based on hemoglobin and hematocrit values, 21.6% and 20.6% of female participants, respectively were anemic. Based on iron intake, 95.1% of female participants had intake lower than the recommendation. Results of this study illustrated that iron deficiency anemia is highly prevalent among adult Saudi women in Riyadh City and suggests actions to eradicate iron deficiency anemia. These actions include increasing nutritional awareness and education for the purpose of changing inappropriate consumption patterns as well as fortification of certain foods in combination with additional intakes of iron from supplements.

Science.gov (United States)

Objective: Sandstorms are metrological events and frequently occur in many regions throughout the world. Sandstorms are a main source of long-distance transport of dust, air pollution and cause various health problems. This study aimed to investigate the acute respiratory and general health complaints in subjects exposed to sandstorm at Riyadh, Saudi Arabia. Methodology: The present descriptive study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia during the period March 2011- June 2012. We selected 517 (308 males, 59.58%) and (209 females, 40.42%), apparently healthy volunteers with mean age 28.6± 3.14 years, who had single outside exposure to sandstorm for the period of 24±2.68 minutes. The acute respiratory and general health complaints were recorded through a comprehensive questionnaire. Results: A large proportion of the subjects who were exposed to sandstorm had complaints of cough 247 (47.77%), runny nose 264(51.06%), wheeze 173(33.46%), acute asthmatic attack 108 (20.88%), eye irritation / redness 252(48.74%), headache 179 (34.62%), body ache 199 (38.5%), sleep disturbance 157(30.36%) and psychological disturbances 194 (37.52%). Conclusion: Exposure to sandstorm causes cough, runny nose, wheeze, acute asthmatic attack, eye irritation / redness, headache, body ache, sleep and psychological disturbances. These results indicate that sandstorm is a prolific source of respiratory and general ailments. It is therefore, suggested that an unnecessary exposure to sandstorm must be avoided. PMID:24353595

Science.gov (United States)

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

Seasonal incidence of airborne fungal allergens in Riyadh, Saudi Arabia.  

Science.gov (United States)

Aerobiological studies to evaluate allergenic fungal spores in the atmosphere of Riyadh were conducted. Burkard personal volumetric sampler were operated as volumetric 'viable' spore traps at two different sites (Al-Batha, a more developed area in the south and Al-Ulia, a less developed area in the north) in Riyadh. Twice a week samplings were carried out over a period of 12 month. The seasonal fluctuations of the most frequent fungi were plotted as 'major' components. The dominant species at the two sites were members of the genera Alternaria, Aspergillus, Cladosporium, Penicillium and Ulocladium. Drechslera, Fusarium, Rhizopus and Stachybotrytis species were minor components or sporadic. Seasonal variations of the total colonies were significantly (p < 0.05) different. They showed higher concentrations in the winter season and the lowest in summer. The Al-Batha site was always higher in spore concentrations than the Al-Ulia site. The results provide valuable information for the diagnosis and prophylaxis of allergic diseases due to airborne fungi. PMID:10560624

Genotyping of Toxoplasma gondii from Rats (Rattus rattus) in Riyadh, Saudi Arabia  

Science.gov (United States)

Toxoplasma 3 main clonal lineages are designated as type I, II, and III; however, atypical and mixed genotypes were also reported. This study was conducted for detection of Toxoplasma gondii genotypes in rats (Rattus rattus) in Riyadh region, Saudi Arabia. PCR test on T. gondii B1 gene was conducted on ELISA IgM positive samples for confirmation of the infection. However, genetic analysis of the SAG2 locus was performed to determine T. gondii genotypes using PCR-RFLP technique. PCR test on T. gondii B1gene showed that 22 (81.5%) out of the 27 ELISA IgM positive samples have T. gondii DNA. Genotypic analysis shows that, of the total 22 PCR positive samples, only 13 (59.1%) were of type II, 7 (31.8%) were of type III, and 2 (9.1%) were of an unknown genotype. It is obvious that the prevalence of both type II and III is high in rats. No reports have been available on T. gondii genotypes among rats in Riyadh region, and only little is known about its seroprevalence in rats. Future studies on T. gondii genotypes in rats using multi-locus markers is needed in Riyadh region, Saudi Arabia for better understanding of T. gondii pathogenesis and treatment in humans and animals.

Prevalence of non-strongyle gastrointestinal parasites of horses in Riyadh region of Saudi Arabia.  

Science.gov (United States)

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

New additions to the scorpion fauna of Riyadh region, Saudi Arabia  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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.

Patterns of tobacco consumption in food facilities in Riyadh, Saudi Arabia  

Science.gov (United States)

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.

Unconventional therapy use among asthma patients in a tertiary care center in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: Unconventional therapy (UT is a therapeutic practice of alternative and complementary medicine that is not currently considered an integral part of modern medical practice. The aim of this article is to investigate the experience of Saudi patients with UT modalities in the treatment of asthma. Materials and Methods: We carried out a cross-sectional study of asthma patients referred to King Abdulaziz Medical City, Riyadh, Saudi Arabia, during the year 2004. Information was collected using a pre-designed questionnaire administered through interviews. Results: Two hundred consecutive patients with a mean age of 52.3 years (±18.7 were included in this study. Sixty-nine (34.5% of those patients used some form of UT in the previous year. There was a tendency to use UT among the older age group ( P = 0.029 and among those with longer duration of disease ( P = 0.009. However, there was no significant correlation observed between the use of UT and gender, FEV 1 , or disease control. The most commonly used form of UT was recitation of Holy Quran (9%, honey (24.5%, herbs (23.5%, cautery (12%, and blackseed (10%. There was no significant correlation between disease control and the use of modalities. Conclusion: Unconventional therapy is frequently practiced by asthma patients in Saudi Arabia, who commonly believe that UT will lead to improvement. The lack of evidence necessitates the fostering of a national project to address the practice of UT.

Analysis of written advertising material distributed through community pharmacies in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

Non prescribed sale of antibiotics in Riyadh, Saudi Arabia: A Cross Sectional Study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Antibiotics sales without medical prescriptions are increasingly recognized as sources of antimicrobial misuse that can exacerbate the global burden of antibiotic resistance. We aimed to determine the percentage of pharmacies who sell antibiotics without medical prescriptions, examining the potential associated risks of such practice in Riyadh, Saudi Arabia, by simulation of different clinical scenarios. Methods A cross sectional study of a quasi-random sample of pharmacies stratified by the five regions of Riyadh. Each pharmacy was visited once by two investigators who simulated having a relative with a specific clinical illness (sore throat, acute bronchitis, otitis media, acute sinusitis, diarrhea, and urinary tract infection (UTI in childbearing aged women. Results A total of 327 pharmacies were visited. Antibiotics were dispensed without a medical prescription in 244 (77.6% of 327, of which 231 (95% were dispensed without a patient request. Simulated cases of sore throat and diarrhea resulted in an antibiotic being dispensed in (90% of encounters, followed by UTI (75%, acute bronchitis (73%, otitis media (51% and acute sinusitis (40%. Metronidazole (89% and ciprofloxacin (86% were commonly given for diarrhea and UTI, respectively, whereas amoxicillin/clavulanate was dispensed (51% for the other simulated cases. None of the pharmacists asked about antibiotic allergy history or provided information about drug interactions. Only 23% asked about pregnancy status when dispensing antibiotics for UTI-simulated cases. Conclusions We observed that an antibiotic could be obtained in Riyadh without a medical prescription or an evidence-based indication with associated potential clinical risks. Strict enforcement and adherence to existing regulations are warranted.

Lupus nephritis among 624 cases of systemic lupus erythematosus in Riyadh, Saudi Arabia.  

Science.gov (United States)

The aim of this article is to study the prevalence, clinicolaboratory features, WHO histological types, therapy and renal outcome of lupus nephritis (LN) in Saudi Arabia. During the 27-year-period (1980-2006), 299 (47.9%) cases of LN were identified among the 624 cases of systemic lupus erythematosus (SLE) follow-up at King Khalid University Hospital, Riyadh. The female:male ratio in LN was 8.3:1, with a mean age of 32 years and a mean age of onset of 23 years. The WHO renal histological types were; Class I (1%), Class II (18.1%), Class III (10%), Class IV (37.1%), Class V (11.7%), and Class VI (2.7%). Azathioprine was given to 43.1% and pulse cyclophosphamide to 65.6% in combination with other drugs. Remission was seen in 226 (75.6%) patients, renal flares in 14 (4.7%), end stage renal disease (ESRD) in 27 (9.0%), death in 18 (6.0%), and 14 (4.7%) lost follow-up. The 5- and 10-year patient survival rates in our whole LN cohort by Kaplan-Meier analysis were 96% and 95%, respectively. The survival did not differ significantly in different LN classes nor did it differ significantly during the three periods of presentation (1980-1990, 1991-2000, and 2001-2006; P > 0.05). The risk factors for poor survival were found to be older age at onset (>50-years age; P = 0.034), ESRD (P = 0.000), and low C3 (P = 0.022). The risk factors for progression to ESRD were older age at onset (>50-years age; P = 0.037), hypertension (P = 0.009), elevated serum creatinine (P = 0.000), and proliferative LN (Classes III, IV; P = 0.013, P = 0.039). Different treatment modalities did not have significant effect on survival in the whole LN cohort (P = >0.05). However, pulse cyclophosphamide favored remission in Classes II, III, IV, and V (P = 0.023). The main causes of death were renal failure (50%) and infections (44.4%). PMID:19381639

Characterisation of MRSA strains isolated from patients in a hospital in Riyadh, Kingdom of Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

Correlation between ultraviolet radiation and global radiation in Riyadh, Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

The global ultraviolet and global radiation were measured and recorded on an hourly basis in Riyadh, Saudi Arabia (lat. 24.6 [degree]N, long. 46.7[degree]) during the period 1984--1989. Global radiation, G, was measured by an Eppley PSP pyranometer (0.285 [<=] [lambda] [<=] 2.8 [mu]m) and an Eppley TUVR radiometer (0.29 [<=] [lambda] [<=] 0.385 [mu]m) was used for the measurement of the ultraviolet radiation, UV. Both instruments were mounted on a horizontal surface. The results showed that the monthly average daily ultraviolet radiation was 197.6 Whm[sup [minus]2]. The ratio of the monthly average daily ultraviolet radiation to the monthly average daily global radiation (K[sub u]) varied between 0.031 to 0.037, with a mean value of 0.034. Comparison with results obtained in Kuwait, Dhahran, and Makkah showed that the data of Riyadh are in good agreement with those of Makkah and Dhahran; however, it underestimates Kuwait data. A regression correlation between K[sub u] and K[sub T] (the ratio of the monthly average daily values of global radiation to extraterrestrial radiation) is developed. Another regression correlation between ultraviolet and global radiation on a hourly basis is also developed.

A Survey on Consumer Need and Opinion about the Community Pharmacists in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This is a questionnaire based survey designed to determine the current status of customers’ views on community pharmacies in Riyadh and focus strategies to expand and promote community pharmacy services in Saudi Arabia. Personal interview survey of 187 consumers, in Riyadh city, was obtained over a period of six weeks (23rd December 2007 to 8th February 2008. The interview questionnaire was designed to ask choice of pharmacy to seek advice, the frequency and the range of health areas for which they seek advice, attitude and views of clients to six items towards pharmacists and their assistants. The results obtained revealed the following: (i to visit a particular pharmacy, respondents claimed it was convenient due to a short distance, convenient working hours, knowledge of staff and excellent services, (ii majority of the respondents asked for advice about Over-The-Counter (OTC medications and prescription advice, while others visited for minor health problems. Willingness to provide advice, quicker services, competence and knowledge about medicines, were revealed to be desired qualities of pharmacists. On attitudes of the customers to a list of six items, majority showed that pharmacists are qualified as health professionals. Some strongly agree that pharmacists are not qualified to discuss with customers their health complaints. It is difficult to conclude the reasons that inhibit clients from seeking the advice of pharmacist. Possibly the lack of privacy and the supermarket style of marketing might influence in deterring the advice seekers. Thus the problem of environment for privacy must be addressed.

Seasonal concentrations of lead in outdoor and indoor dust and blood of children in Riyadh, Saudi Arabia.  

Science.gov (United States)

Because detrimental effects of exposure to lead (Pb) on human health have been observed, we previously investigated concentrations of Pb in water supplies and blood of adult residents of Riyadh, Saudi Arabia. The objectives of the present study were to: (1) examine seasonal rates of deposition of Pb in dust in several areas of Riyadh city, (2) measure concentrations of Pb in both outdoor and indoor dust, (3) compare concentrations of Pb in dust in Riyadh with those reported for other cities, and (4) quantify Pb in blood of children living in Riyadh. Mean, monthly deposition of PB in outdoor dust was 4.7 × 10(1) ± 3.6 tons km(-2), with a mean Pb concentration of 2.4 × 10(2) ± 4.4 × 10(1) ?g/g. Mean, monthly deposition of Pb in indoor dust was 2.7 ± 0.70 tons km(-2), with a mean concentration of 2.9 × 10(1) ± 1.5 × 10(1) ?g Pb/g. There was a significant (P < 0.01) correlation between concentrations of Pb in outdoor and indoor dust. There was no correlation between concentrations of Pb in indoor dust and that in blood of children of Riyadh, whereas there was a weakly significant (P < 0.05) correlation between concentrations of Pb in outdoor dust and that in blood of children. The mean (±SD) concentration of Pb in blood of children in Riyadh was 5.2 ± 1.7, with a range of 1.7-1.6 × 10(1) ?g/dl. Concentrations of Pb in blood of 17.8 % of children in Riyadh were greater than 10 ?g/dl, which is the CDC's level of concern. PMID:24213703

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

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

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)

Availability and needs of herbal medicinal information resources at community pharmacy, Riyadh region, Saudi Arabia.  

Science.gov (United States)

A cross-sectional survey of community pharmacists in Riyadh region, Saudi Arabia was conducted over a period of 6 months from July through December 2011. Data collection was carried out using a structured self-administered questionnaire. The survey questionnaire consisted of a brief introduction to the study and eleven questions. The questions consisted of close ended, multiple-choice, and fill-in short answers. A stratified random sample of one thousand and seven hundred registered pharmacy practitioners all over Saudi Arabia were randomly chosen to respond to the survey. The data from each of the returned questionnaire were coded and entered into Statistical Package for the Social Sciences (SPSS) version 19 software (SPSS Inc., Chicago, IL, USA) which was used for statistical analysis. Only one thousand four hundred one pharmacists responded to the survey (response rate is 82.4%) with a completely answered questionnaire. The study results show that 59.7% of the participants sometimes discuss herbal medicine use with their patients, while only 4.25% never discuss it. The study shows 48.5% of participated pharmacists record herbal medicine use sometimes where only 9.4% of them never did so. However, with regard to initiation of the discussion, the study shows that 44.3% of the respondents reported that patients initiate herbal issue discussion while 20.8% reported that pharmacists initiate the discussion. This discussion was reported to be a one time discussion or an ongoing discussion by 14.3% or 9.9% of the respondents respectively. According to the study results, respondents reported that the most common barriers that limit discussing herbal medicines' use with their patients were lack of time due to other obligations assigned to the community pharmacist (46%), lack of reliable resources (30.3%), lack of scientific evidence that support herbal medicine use (15.2%), or lack of knowledge of herbal medicines (13.4%). Yet, a small number of respondents was concerned about interest in herbal medicines (9.1%) and other reasons (2.4%). So it is urgent to ensure that pharmacists are appropriately educated and trained. Extra efforts are needed to increase the awareness of pharmacists to adverse drug reactions reporting system at Saudi Food and Drug Authority. Finally, more consideration to herbal issues should be addressed in both pharmacy colleges' curricula and continuous education program.. PMID:24227954

Characterization of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae from Riyadh, Saudi Arabia.  

Science.gov (United States)

The objectives of this study were to determine the prevalences, genotypes, and clonal relationships of extended-spectrum beta-lactamase (ESBL)-producing strains in 98 Klebsiella pneumoniae isolates from Riyadh. The prevalence of ESBLs in these strains was 37·75%. All isolates that were confirmed to have ESBLs were completely resistant to amoxicillin/clavulanate, aztreonam, cefotaxime, ceftazidime, cefoxitin, and gentamicin and were susceptible to tigecycline, colistin, and imipenem. In total, 16·6, 77, and 91·6% of isolates were resistant to amikacin, ciprofloxacin, and piperacillin/tazobactam, respectively. The prevalences of isolates producing the beta-lactamases SHV, CTX-M, and TEM were 91·9, 86·5, and 54·05%, respectively. The most frequent ESBL gene detected was blaCTX-M-15, which was observed in 75% of isolates. Other frequent ESBL genes were blaSHV-12 (29·73% of isolates) and blaSHV-5 (5·4% of isolates); additionally, blaCTX-M-3, blaCTX-M-27, blaCTX-M-57, and blaCTX-M-82 were each detected in one isolate. Pulsed-field gel electrophoresis (PFGE) analysis revealed the presence of diverse and unrelated clones. The high prevalence of ESBL producers among the strains examined in our study was not due to the spread of a single clone of bacteria. Clone A was detected in six isolates, indicating intra-hospital spread. Our study documented a high prevalence of the CTX-M-15 product in K. pneumoniae and demonstrated that SHV-12 was also highly prevalent. This study represents the first report of CTX-M-3, CTX-M-27, CTX-M-57, and CTX-M-82 beta-lactamases in K. pneumoniae isolates from Saudi Arabia. PMID:24091155

Variation of radiation doses from CT pediatric procedures in large medical centers in Riyadh, Saudi Arabia  

International Nuclear Information System (INIS)

Radiation doses to pediatric patients from CT procedures were investigated for three (3) large medical centers in Riyadh, Saudi Arabia. The medical centers have different CT multislice and spiral CT systems. The doses were evaluated in terms of the weighted CT dose index (CTDiw), dose length product (DLP) and effective dose for risk assessment. The chest and abdomen-pelvis procedures were selected for dose estimation because of the high workload. Pediatric patients from neonate to less than 15 years old were included in the study. The pediatric patients were grouped into ages 0 (neonates), 1, 5 and 10 years old. The weight and height were taken from the National Study of Growth Monitoring of 0-5 Years Saudi Children and from patient records. The equivalent cylindrical diameter (ECD) was determined to estimate the patient diameter. The estimation of ECD uses the relationship ECD = 2 [weight/?(height)]0.5. The scan protocols have about 7 models for different weight groups. The scan parameters for the commonly used model was selected for each CT system. The data on peak kilovoltage, mA, rotation time, slice thickness, pitch and total scan time were retrieved. The CTDIW and the DLP of each unit were determined using the quality control test data. The CTDIW and DLP values were compared with the values displayed on the monitor. The variation of the CTDIW and DLP values for the different CT system was evaluated. The effective doses due to CT were estimated using the IMPACT dose calculator and the mean was determined for each age group. Preliminary results show that mean effective dose of the 1 year old age group is about 7% higher that the mean effective dose for 0 age group. The effective dose for the females do not significantly vary from the males for age group 0 but for age group 1, the effective doses of the males differ by about 12%. This is due to the difference in the weight. Comparing the effective dose delivered by the different systems, the variation would be about 15 to 30%. The difference in the effective doses for chest between CT systems can differ by about 7% and for abdomen-pelvis by about 20%]. The Pearson correlation coefficient between effective dose and ECD was determined and evaluated. The peak kilovoltages vary with weight and improve image quality. The study is aimed to provide a data base for the CTDIW and DLP variations for the different age groups of pediatric patients using different CT systems that can be used for dose optimization. It is also aimed to investigate strategies for reducing pediatric doses which include scan parameters, CTDIW and DLP values

A prospective study of the incidence and characteristics of septic arthritis in a teaching hospital in Riyadh, Saudi Arabia.  

Science.gov (United States)

To find the incidence, characteristics, method of treatment, and outcome of synovial fluid culture-positive septic arthritis, all newly admitted cases of synovial fluid culture-positive septic arthritis to King Khalid University Hospital, Riyadh, Saudi Arabia were studied prospectively during August 2005 to July 2006 and only those with positive synovial fluid culture septic arthritis were included in the analysis. Demographic, clinical, hematological, biochemical, microbiological, radiological, and histopathological data along with the interventional and surgical procedures and the functional outcome related to the joint involved were recorded. Of the 42 patients admitted, only 12 fulfilled the study criteria of having positive synovial fluid culture. Annual incidence was estimated to be 2.13 per 100,000 inhabitants. The mean disease duration before diagnosis and treatment was 10.42 +/- 2.9 days. The affected joints were six knees, three hips, two shoulders, and one with hip and knee involvement. Two patients had rheumatoid arthritis, two had osteoarthritis, and one had sickle cell disease. The most common infecting organism was Staphylococcus aureus, which caused eight of the infections (66.7%), one Salmonella, one Staphylococcus epidermidis, one Enterobacter cloacae, and one Mycobacterium tuberculosis. The septic arthritis in 4 (33.3%) cases followed previous orthopedic intervention. Blood cultures were positive in three patients, all with S. aureus. White blood cell count was elevated in 3 (25%) patients. All patients received intravenous antibiotic for the initial 2 weeks, the most commonly used antibiotic was flucloxacillin. There were no deaths due to septic arthritis. The functional outcome was excellent to good. Septic arthritis is less prevalent in our community, and the most frequent organism is Staphylococcus. However, special risk factors favor other organisms such as Salmonella and Enterobacter. Previous orthopedic intervention is an important risk factor. Mortality due to septic arthritis is lower than reported elsewhere. PMID:18584268

The Quality of Medicines in Community Pharmacies in Riyadh, Saudi Arabia: A Lot Quality Assurance Sampling (LQAS-Based Survey  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To classify community pharmacies (CPs in Riyadh, Saudi Arabia, in terms of the quality of medicines sold by them, using the lot quality assurance sampling (LQAS technique with a predefined threshold. Methods: Riyadh CPs were divided into 2 categories (“lots” for the purpose of LQAS, i.e., chain and independent CPs. Upper and lower rate thresholds for CPs that sell low-quality medicines were predefined as 20% and 5%, respectively. Consumer and provider risks were predefined as 0.05 and 0.10, respectively. The calculated number of randomly selected CPs required in each lot was 36; then, sale of low-quality medicines in >3 CPs implies a prevalence of >20% of such CPs according to LQAS. A randomly selected brand of amoxicillin (selected as a quality indicator of medicines because it is both widely counterfeited and heat-sensitive was purchased from each pharmacy by a “mystery shopper”, checked for authenticity, and analyzed for drug content and content uniformity using a validated HPLC method. Results: Substandard amoxicillin was purchased in 9 pharmacies (4 chains and 5 independent. Both lots were thus rejected as unacceptable, which may indicate that consumers in Riyadh are at risk of purchasing substandard medicines at CPs. Conclusions: The quality of medicines sold in CPs in Riyadh did not meet our acceptability criterion, and appropriate intervention by decision makers is recommended. LQAS proved to be a practical, economical, and statistically valid sampling method for surveying the quality of medicines. It should enable decision makers to allocate resources for improvement more efficiently.

A study on the behaviour of TLD-100 glow peaks at extreme ambient temperatures in Riyadh (Saudi Arabia))  

International Nuclear Information System (INIS)

In this study, the temperature-induced variations in the TLD-100 response and the modifications in its glow peaks are investigated in real environmental exposure conditions in Riyadh (Saudi Arabia)), where ambient temperatures during summer reach >45 deg. C and with relative humidity of 137Cs prior to deployment; another was irradiated to the same dose after deployment, while the last group was left unirradiated. Analysis of glow curves was done using commercially available glow curve deconvolution software (CGCD). Monthly variations in peak 3, 4 and 5 areas relative to the corresponding peak areas of a prompt glow curve are presented. Results of this study show good TL signal compensation between peaks 4 and 5 at all ambient temperatures encountered in this experiment, despite the observed individual variations experienced by each of these peaks. The sum of peak 4 and 5 areas is constant to within ?10%, for both pre- and post-irradiated dosemeters, during this 12-month cycle. (authors)

Test for Local Insect Traps against some Solanacea Insects Plant under Green House Conditions in Riyadh, Saudi Arabia  

International Nuclear Information System (INIS)

Trapping efficiency of seven different colored sticky traps (Green, Fluorescent yellow, Orange, Pink, red, White and Yellow) was evaluated in some solanacea plants, tomatoes (Lycopersicon esculentum), eggplant (Solanum Magellan) and sweet pepper (Capsicum spp.) crops, for whitefly (Bemis ia airlifting), leaf miners (Liriomyza trifolii), thrips (Thrips tabaci) in Riyadh, Saudi Arabia. The traps were placed at four different heights (0.5, 1.0, 1.5 and 2.0 m above the ground). The experiment was laid out in a Completely Randomized Block Design (CRBD) with four replications during autumn 2001, spring and autumn 2002. Significantly high insect populations were trapped on Fluorescent yellow, yellow and green colored sticky traps. No significant differences were witnessed between mean numbers of various insects caught on sticky traps placed at different heights but more insects were trapped at 0.5 - 1.5m. (author)

The growth pattern of Saudi Arabian pre-school children in Riyadh compared to NCHS/CDC reference population.  

Science.gov (United States)

This study compares the growth patterns of Saudi Arabian pre-school children aged 0-5 years to a reference population of American children documented by the National Center for Health Statistics/Centers for Disease Control (NCHS/CDC). The anthropometric data of weight, height and age were collected in a cross-sectional study of Saudi Arabian children in Riyadh, the capital of Saudi Arabia. The sample selection was accomplished by a 3-stage stratified random procedure, basing the stratification on location and a socio-economic index. A total of 3,795 children comprising 55.2% males and 44.8% females had complete basic anthropometric measurements among other variables. Analyses were effected by using the WorHealth Organization/Centers for Disease Control (WHO/CDC) standard software programme for calculating nutritional indicators. A combination of height for age (as an indicator of stunting) and weight for height (as an indicator of wasting) showed that a sizeable proportion (78.1%) have normal or slightly above normal nutritional status. A small proportion of the children (1.4%) were below -2.0 SD scores of the reference population for weight for height and for age. Overall, Saudi Arabian children are slightly shorter and thinner than their American counterparts. An important finding in weight for height was that nearly 20% of the children were below -2 SD scores of the reference population median. However, due to the very high per capita income, and the fact that food and other essential items are subsidised by the government, the deficits from this reference population may be attributed to inadequate health education nutrition programmes, genetic and other social factors including reproductive behaviour, rather than malnutrition.

Molecular epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) isolates from major hospitals in Riyadh, Saudi Arabia.  

Science.gov (United States)

The few studies that have reported the incidence of methicillin-resistant Staphylococcus aureus (MRSA) in Saudi Arabia have indicated that a diverse number of circulating MRSA strains have been detected in several major hospitals. Thus, this study was designed to track the presence of MRSA strains in major hospitals in Riyadh, Saudi Arabia, and perform comparative chromosomal DNA analysis of MRSA strains for epidemiological investigation using pulsed-field gel electrophoresis (PFGE). Correlation of the PFGE types generated with microbiological and clinical data of the isolates was attempted. Screening for decreased susceptibility to vancomycin among the isolates was also done. A dendogram was generated using PFGE macrorestriction fragments and 6 types were identified (M1-M6) with M1 being predominant and widespread. A clear link between PFGE types and some clinical and microbiological data available for the strains was found. For example, M1 was statistically associated with male patients, whereas the unique types were associated with female patients, M2 was associated with isolates from wounds and age group <5 years, and M4 was associated with isolates from patients admitted to intensive care units. M5 was highly correlated with low sensitivity to linezolid. No vancomycin-resistant isolates were detected. PMID:17898849

Streptococcus pneumoniae serotypes/serogroups causing invasive disease in Riyadh, Saudi Arabia : Extent of coverage by pneumococcal vaccines  

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND : Serogroup distribution of sterile site pneumococcal isolates varies between developing and developed countries as well as between different geographical regions. The potential efficacy of any pneumococcal vaccine depends on the degree of representation of the prevalent serogroups in the vaccine. We conducted this study to determine the prevalent pneumococcal serogroups causing invasive infections in Riyadh, Saudi Arabia and to estimate the coverage by the various pneumococcal conjugate vaccines. METHODS : S. pneumoniae isolated between February 2000 and November 2001 from sterile sites of patients of all age groups were collected from 8 major hospitals in Riyadh and serogrouped using the latex agglutination method. RESULTS : Isolates from 78 patients, 72% of whom were children, were studied. Eighty-eight percent of the isolates belonged to only 10 serogroups/serotypes, namely 6 and 19, 1 and 15, 14 and 23, 7, 18 and 22, in descending order of frequency. Potential coverage of the 7-valent, 9-valent, and 11-valent conjugate vaccines were 54%, 65% and 73%, respectively. The rate of reduced penicillin susceptibility in the serogroups represented in the 7-valent conjugate vaccine was significantly higher than in the non-vaccine serogroups (62% vs. 25%; P =0.0023 CONCLUSION : The currently available 7-valent pneumococcal conjugate vaccine provides sub-optimal coverage to serogroups causing invasive diseases in our community. However, this vaccine would be a useful adjunct to penicillin prophylaxis in at-risk patients in the community. The effectiveness of the vaccine would be greater if serotype 15 could be included.

Assessment and heavy metal behaviors of industrial waste water: A case study of Riyadh city, Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

Genetic diversity of OXA-51-like genes among multidrug-resistant Acinetobacter baumannii in Riyadh, Saudi Arabia.  

Science.gov (United States)

We explore the genetic diversity of class D oxacillinases, including OXA-23, -24 (-40), -58 and, particularly, the intrinsic OXA-51-like genes, among multidrug-resistant (MDR) Acinetobacter baumannii strains from inpatients at a tertiary care hospital in Riyadh, Saudi Arabia. Sequence-based typing (SBT) of the OXA-51-like gene was carried out on 253 isolates. Selected isolates (n?=?66) were subjected to multilocus sequence typing (MLST). The polymerase chain reaction (PCR) typing results showed that all isolates (n?=?253) contained the OXA-51-like and OXA-23 genes. However, the OXA-58 gene was detected in five isolates. Further, none of the isolates had the OXA-40 (identical to the OXA-24) gene. SBT revealed a high OXA-51-like genotypic diversity and showed that all isolates were clustered into four main groups: OXA-66 (62.3 %), followed by OXA-69 (19.1 %), OXA-132 (7.6 %) and other OXA-51-like genes (10.3 %), including OXA-79, -82, -92, -131 and -197. MLST revealed four main sequence types (STs), 2, 19, 20 and 25, among the isolates, in addition to six isolates with newly designated ST194-ST197 singletons. Further, a high prevalence (81.4 %) of OXA-66 and OXA-69-like genes in A. baumannii was identified. More studies are essential in order to explore the molecular mechanisms that confer carbapenem-resistant phenotypes for A. baumannii isolates and to investigate the genetic diversity of other OXA-D genes.

Extended-spectrum and metallo-beta-lactamases among ceftazidime-resistant Pseudomonas aeruginosa in Riyadh, Saudi Arabia.  

Science.gov (United States)

We investigated the extended-spectrum (ESBLs) and metallo-beta-lactamases (MBLs) among Pseudomonas aeruginosa isolates in Saudi Arabia. Disc susceptibility testing was performed on 200 P. aeruginosa isolates collected during 2010 at the Armed Forces Hospital in Riyadh, with MIC testing and phenotypic screening for ESBLs and MBLs carried out on those found to be ceftazidime resistant. Genes for ESBLs and MBLs were sought by PCR. Thirty-nine (19.5%) P. aeruginosa isolates were ceftazidime resistant, mostly with considerable resistance to other antibiotics except colistin. Twenty-three of these 39 (59%) appeared ESBL positive and 16 (41%) had MBLs. bla(VEB), and bla(GES) genes were found in 20 (86.95%), and 5 (21.74%) of 23 ESBL-positive isolates, respectively whilst bla(VIM) was detected in all 16 MBL-producers. bla(OXA-10-like) often accompanied bla(VEB), bla(VIM) or bla(GES). Several isolates had similar antibiogram and ?-lactamase profiles, and may represent outbreaks; nevertheless, the collection was not dominated by any single clone. This dominance of acquired ceftazidime-inactivating beta-lactamases, often in combination is in contrast to the situation in Europe and the USA, where most ceftazidime resistance in P. aeruginosa is attributable to AmpC and efflux.

Heavy Metals Accumulation in Rhazya stricta L. Plant Growing on Industrial Wastewater of Riyadh City, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This study evaluated the potential of Rhazya stricta L. growing on a surrounding area of the second industrial zone (24°39.8’ N; 46°57’ E, east of Riyadh, Saudi Arabia. Plant and the associated soil samples were collected and analyzed for total Cr, Fe, Ni, Cu, Zn, Cd and Pb concentration. The degree of contamination by those heavy metals in soil and transfer to Rhazya stricta has been estimated. The results showed a medium contamination of soil heavy metal content with respect to Cd and Pb. The total concentration of Fe, Cr, Ni, Zn and Cu in shoots of Rhazya stricta was 275, 5.30, 10.5, 27.5 and 8.30 mg kg-1, respectively. On the other hand, the total concentration of heavy metals in the roots was as follows (mg kg-1: Fe: 0.1; Cr: 0.5; Ni: 3.0; Zn: 0.8 and Cu: 1.6. Heavy metals (Cr, Ni, Cu and Zn tended to be accumulated in the roots Rhazya stricta rather than the stems and leaves expect for Zn. The calculated accumulation coefficient of heavy metals in the roots was higher than that in stems or leaves. The Rhazya stricta plant exhibiting Translocation Factor (TF values less than one except for total Zn (1.10-1.60. The results indicated that, Rhazya stricta plant could not suitable for heavy metals extraction from the contaminated studied soil but can be used as an indicator for soil contamination with some heavy metals (Cd, Cu, Pb and Zn and also to minimize heavy metals mobility in contaminated soils.

Characterization of 137Cs in Riyadh Saudi Arabia Soil Samples  

Directory of Open Access Journals (Sweden)

Full Text Available The current study was conducted primarily to investigate and estimate 137Cs activity concentrations and the external dose rate due to fallout radionuclide 137Cs. Soil samples were collected from different 25 locations at Riyadh Province and analyzed using low level ?-spectrometry equipped with HPGe-detector. 137Cs activity concentrations and calculated dose rate were found in the range of 0.8 - 3.1 Bq·kg–1 and 0.05 to 0.8 nSv·h–1 with an average value of 1.70 ± 0.7 Bq·kg–1 and 0.11 ± 0.05 nSv·h–1 respectively. The measured 137Cs activity concentration range was compared with the reported ranges in the literature from some of the other locations in the world. Results obtained in this study show that 137Cs concentration is of a lower level in the investigated area. However, the range of 137Cs concentrations observed in this study is significantly high relative to similar data reported from Libya. The average value of estimated external effective dose rate is found far below the dose rate limit of of 1.0 mSv·y–1 for members of the general public recom-mended by ICRP as well as the external gamma radiation dose of 0.48 mSv·y–1 received per head from the natural sources of radiation assessed by (UNSCEAR, 2000. It is concluded that 137Cs soil contamination does not pose radia-tion hazards to the population in the investigated areas.

Directory of Open Access Journals (Sweden)

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.

Trends in antibiotic susceptibility patterns and epidemiology of MRSA isolates from several hospitals in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus (MRSA, is associated with high morbidity and mortality rates with rapid development of resistance. Methods A total of 512 MRSA isolates were procured from 6 major hospitals in Riyadh, Saudi Arabia and antibiotic susceptibilities and MICs were documented against several antibiotics and vancomycin. SPSS version 10 was used for statistical analysis. Results The prevalence of MRSA in the study hospitals ranged from 12% to 49.4%. Mean patient age was 44 years with males constituting 64.4% and females 35.6%. Approximately 41.5% of the isolates came from patients in the extreme age groups. MIC for vancomycin was in the susceptible range for all isolates ranging from 0.25 to 3 ug/ml. The overall susceptibility of MRSA to the various antibiotics tested was: fusidic acid 4.3%, sulfamethoxazole/trimethoprim 33.8%, gentamicin 39.6%, mupirocin 77.0%, gatifloxacin 78.9%, chloramphenicl 80.7%, linezolid 95.1%, quinupristin/dalfopristin 100%. Some differences were noted in the resistance of isolates among the participating hospitals reflecting antibiotic usage. On the whole, inpatient isolates (accounting for 77.5% of the isolates were more resistant than outpatient isolates (22.5% except for linezolid. Quinupristin-dalfopristin and linezolid are the most effective antibiotics tested against inpatient isolates while quinupristin-dalfopristin and gatifloxacin seem to be the most effective against outpatient isolates. Approximately one forth of the isolates are no longer susceptible to mupirocin used for eradication of the carrier state reflecting resistance developing after widespread use. Trends over time show a tendency towards decreased susceptibility to gatifloxacin and linezolid with increasing susceptibility to gentamicin and sulfamethoxazole/trimethoprim. Conclusion Quinupristin/dalfopristin and linezolid are two valuable additions to our antimicrobial armamentarium, but resistance has already been described. To preserve their value, their use should be limited to those rare cases where they are clearly needed. Fusidic acid, the local antibiotic, gentamicin and trimethoprim/sulfamethoxazole should not be relied upon for treatment of MRSA infections, at least empirically as the percentage of susceptible isolates is very low.

Science.gov (United States)

Background In this observational study, we aimed to see whether transition in Saudi students entering university life could be a breeding stage for cardiometabolic risk factor emergence and clustering. Methods A total of 1878 apparently healthy Saudi students of the Preparatory Year, King Saud University, Riyadh, KSA (1112 men and 766 women) spanning 2 academic years were included. They were divided into 2 groups based on the validated perceived stress test (PST). Anthropometrics were obtained and fasting blood samples were collected for measurement of fasting blood glucose and a lipid profile. Results PST score (>27) considered indicative of stress was noted in 44.4% of students. The prevalence of this score was higher in women than in men (49.7% versus 40.7%). The prevalence of obesity, hypertension and dyslipidemia was significantly higher in men than women (p?Saudi students entering universities. This study sheds light on the social responsibility of universities in promoting a healthy lifestyle, particularly in this age group, when exposure to different kinds of stressors may result in body weight and metabolic changes.

Directory of Open Access Journals (Sweden)

Full Text Available 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.

Perception among medical students in Riyadh, Saudi Arabia, regarding alcohol and substance abuse in the community: a cross-sectional survey  

Directory of Open Access Journals (Sweden)

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.

Objective: To analyse and critically assess the information presented in print pharmaceutical a [...] dvertisements 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.

Aluminum, Cadmium and Microorganisms in Female Hair and Nails from Riyadh, Saudi Arabia1A.R. Hashem and 2K.F. Abed  

Directory of Open Access Journals (Sweden)

Full Text Available Mineral analysis from hair and nails may be useful in knowing the elemental concentration in body tissue. This study was conducted to ascertain levels of aluminum, cadmium and microorganisms in hair and nails from 20 adult Saudi women aged between 20-25 years old from Riyadh, Saudi Arabia between December 2005 and January 2006. Metal analysis were carried out by Atomic Absorption Spectroscopy (AAS using Electrothermal atomization (Pye Unican Sp9 and done according to Ellis, Ramirez, Buchanan and Gibbons methodology. The levels of aluminum was 5.23±1.31 to 26.02±3.65 ?g g-1 and cadmium was 0.04±0.01 to 0.014±0.002 ?g g-1 in hair and nail samples. Aluminum is more significantly concentrated in the nails than hair (p<0.0001. Cadmium levels were significantly higher in hair than in nails (p<0.0001. However, levels of aluminum are higher in both hair and nail samples compared to cadmium (p<0.0001. These levels are much lower compared to reports from other countries like Spain, Germany, Norway and USA. Microbial isolates revealed Microsporum, Staphylococcus, Klebsiella, Bacillus and Pseudomonas. Fungal isolates included Penicillium, Trichophyton and Aspergillus. These are all known bacterial and fungal isolates from the soil. Despite lower level findings of aluminum and cadmium compared to other countries, further information is needed on concentrations of elements in the hair of individuals with known exposures to trace elements. Our levels are within the worldwide range for normal occupationally exposed population despite the booming economic growth and rapid industrialization of Saudi Arabia.

Efficiency of Integrated Geophysical techniques in delineating the extension of Bauxites ore in north Riyadh, Saudi Arabia  

Science.gov (United States)

We exploit the integration of Ground Penetrating Radar (GPR) techniques, magnetic gradiometry, resistivity measurements and seismic tomography for the high-resolution non-invasive study for delineating the subsurface Bauxite layer in Zabira locality, north of Riyadh. Integrated GPR, magnetic gradiometry resistivity and seismic refraction are used in the case of high contrast targets and provide an accurate subsurface reconstruction of foundations in sediments. Resistivity pseudo-sections are in particular useful for the areal identification of contacts between soils and foundations while GPR and magnetic gradiometry provide detailed information about location and depth of the structures. Results obtained by GPR, Magnetics and resistivity shows a very good agreement in mapping the bauxite layer depth at range of 5 m to 10 m while the depth obtained by seismic refraction was 10 m to 15 m due to lack of velocity information.

Blended learning in Saudi universities: challenges and perspectives  

Directory of Open Access Journals (Sweden)

Full Text Available This study is an attempt to investigate the nature of obstacles and challenges encountered at Saudi universities while implementing a blended learning approach. A literature review of blended learning rationale and designs, and the status of web-based education in Saudi higher education are demonstrated. Three main challenges of applying blended learning in Saudi higher education are addressed. One major challenge to be considered in the implementation of blended learning in Saudi universities is the adaptation of this element in the traditional university culture. Finding the right design of blended learning is another challenge that is discussed in detail. Furthermore, the time issue is considered a crucial challenge facing blended learning faculty. Practical recommendations that would facilitate transition to a blended learning university environment are presented. It is hoped that this study will help to provide insight for the faculties and the decision-makers throughout higher education in Saudi Arabia. Although this investigation is specifically related to the implementation of blended learning in the universities of Saudi Arabia, we are confident that the assumptions and recommendations contained herein will be of great value to other populations facing similar challenges.

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)

Analysis of serum trace elements-copper, manganese and zinc in preeclamptic pregnant women by inductively coupled plasma optical emission spectrometry: a prospective case controlled study in Riyadh, Saudi Arabia  

Science.gov (United States)

Preeclampsia complicates 2-8% of all pregnancies and is one of the leading causes of maternal mortality and pre-term delivery in world. In concern to the increasing number of preeclamptic cases and lack of data about the interrelation between levels of trace elements and preeclampsia, we conducted a hospital based case-control study to assess the risk of preeclampsia in relation to concentrations of trace elements like copper, manganese and zinc in a hospital in Riyadh, Saudi Arabia. The study consisted of 120 pregnant women divided into three groups of 40 each - control, HR group and the PET group. The serum levels of Cu, Mn and Zn were estimated by inductively coupled plasma optical emission spectrometry. Analysis of trace elements revealed that mean values of Cu, Mn and Zn were 2.01 ± 0.43, 0.125 ± 0.07 and 1.30 ± 0.83 mg/L respectively in control. In preeclamptic group, the mean values of Cu, Mn and Zn were 1.554 ± 0.53, 0.072 ± 0.06 and 0.67 ± 0.59 mg/L respectively. Levels of Cu and Zn were found to decrease significantly (P Cu, Mn and Zn and systolic blood pressure. However the correlation of Cu, Mn and Zn with maternal age, gestational age, BMI, systolic and diastolic blood pressure was statistically insignificant. In conclusion, our study suggests that preeclamptic patients have considerably lower levels of Cu, Mn and Zn compared to control and reduction in serum levels of copper, manganese, and zinc during pregnancy might be possible contributors in etiology of preeclampsia.

Emirati and Saudi Students’ Writing Challenges at U.S. Universities  

Directory of Open Access Journals (Sweden)

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

Saudi English-Major Undergraduates' Academic Writing Problems: A Taif University Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available This study attempted to investigate Saudi English-major undergraduates studying at Taif University to identify a the types of academic writing Saudi English-major undergraduates carry out at English departments, b Saudi English-major undergraduates' writing problems, c the reasons behind Saudi English-major undergraduates' writing problems and d the solutions to overcome Saudi English-major undergraduates' writing problems. To collect data for this purpose, senior faculty members were interviewed and a 32-item structured Likert-scale questionnaire was developed that was administered to 75 English-major students (sophomores, juniors & seniors studying at foreign languages department, Taif University. Data generated through the questionnaire were subjected to descriptive analyses and mean and standard deviation were recorded using SPSS. The findings of this study reveal that Saudi English-major undergraduates are very weak in writing skills and commit lots of errors in their academic writings and are usually engaged in sentence-level or at the maximum at paragraph-level academic writing and they do not consider it important at this level to write different kinds of essays. It has been strongly recommended that the language courses should be increased to strengthen all the language skills in general and writing in particular, motivate the students to use English with the teachers as well as with each, introduce modern and novel teaching techniques, equip the classrooms with necessary audio-visual aids, diagnose students’ writing problems in the beginning of their studies at university, tailor the course contents according to their needs, introduce group/pair work, peer correction, use dictionaries frequently etc.

Extra-pulmonary tuberculosis in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Studies from developed countries have reported that extra-pulmonary tuberculosis (EPTB is on the rise due to the human immunodeficiency virus (HIV epidemic. However, similar studies from high-burden countries with low prevalence of HIV like Saudi Arabia are lacking. Therefore, we conducted this study to investigate demographic and clinical characteristics of patients with pulmonary and extra-pulmonary tuberculosis. A retrospective analysis was carried out on all patients (n=431 with a culture - proven diagnosis of tuberculosis seen at University teaching hospital, Riyadh, Saudi Arabia from January 2001 to December 2007. A total of 183 (42.5% pulmonary tuberculosis (PTB and 248 (57.5% extra-pulmonary TB (EPTB cases were compared in terms of age, sex, and nationality. There were 372 Saudis (SA (86.3% and the remaining non-Saudis (NSA 59 (13.7%. The age distribution of the PTB patients had a bimodal distribution. EPTB was more common at young age (20-29 years. The proportion of EPTB cases was significantly higher among NSA patients (72.9% compared to SA patients (55.1%. Females had higher proportion (59.5% of EPTB than males (55.6%. The most common site was lymph node tuberculosis (42%. In conclusion, our data suggest that EPTB was relatively common in younger age, female gender and NSA. Tuberculosis (TB control program may target those populations for EPTB case-finding.

Saudi Arabia walks a tightrope  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Saudi diplomacy seems more active than ever. This has to do with three recent major regional developments: the summer 2006 war between Israel and Hezbollah, the violent clashes between Hamas and Fatah in the occupied Palestinian territories, and the Iraqi quagmire. In each of these, the role of Iran is difficult to overlook and this is troubling Riyadh. Yet Saudi Arabia has difficulty in responding to Iran's assertiveness: it wants to contain Tehran's ambitions, but at the same time it cannot...

International Nuclear Information System (INIS)

Implementation of a pilot screening program for prostate cancer among Saudi patients that would serve as a nucleus for a Kingdom-wide screening program. A prospective study on 1,213 Saudi males between 50-80 years of age who attended the Outpatient Department at King Fahd Hospital of King Faisal University, Al-Khobar, Kingdom of Saudi Arabia during a period of 18 months (April 2001-October 2002). They were included at random from different clinics including the urology clinic. Free and total prostate specific antigen (PSA) and digital rectal examination (DRE) of the prostate were performed in all patients. Patients with abnormal DRE or PSA were scheduled for transrectal ultrasound (TRUS) and ultrasound guided biopsy of the prostate. Abnormal DRE or PSA were present in 84 out of 1,213 patients. Only 63 patients agreed to have TRUS and ultrasound guided biopsies. Prostate cancer was confirmed in 14 out of 1,192 patients who completed the study (1.17%). The incidence of prostate cancer among Saudi men in this hospital based study is low. A population based screening for prostate cancer may reveal the incidence of this disease. (author)

Mental health system in Saudi Arabia: an overview  

Directory of Open Access Journals (Sweden)

Full Text Available Naseem Akhtar Qureshi,1 Abdulhameed Abdullah Al-Habeeb,2 Harold G Koenig3 1General Administration for Research and Studies, 2Mental Health and Social Services, Ministry of Health, Riyadh, Saudi Arabia; 3Department of Psychiatry and Behavioral Sciences, Duke University Medical Center, Durham, NC, USA Background: There is evidence that mapping mental health systems (MHSs helps in planning and developing mental health care services for users, families, and other caregivers. 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.

Stroke in Saudi children  

International Nuclear Information System (INIS)

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

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.

Factors affecting the internal brain drain of Saudi healthcare professionals  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To investigate factors affecting the internal brain drain of healthcare professionals in the Kingdom of Saudi Arabia. Methods: A cross-sectional study was conducted using an anonymous self-administered online questionnaire sent to all Saudi students enrolled in healthcare profession programs in North America. The data was collected between January and March 2008 at the University of Illinois at Chicago, Chicago, Illinois, United States of America. Results were analyzed using logistic regression analyses. Results: A total of 377 completed questionnaires were returned. Results revealed that 71% of respondents intended to return to work within the 2 major urban cities (Riyadh and Jeddah. Respondents who completed their undergraduate studies in a large city were more likely to work in the same city (odds ratio [OR]=3.2; p=0.000; 95% confidence interval [CI] = 2.0-5.2. Furthermore, 51% of the students were willing to work in a rural area for a 50% or more increase in their salary. Finally, men were more willing to work in a rural area for a financial incentive (OR=2.3; p=0.006, 95% CI = 1.3-4.3. Conclusion: This study suggests that realistic financial incentives would probably not suffice to attract Saudi healthcare providers to rural areas. The provision of medical schools in smaller cities and rural areas is predicted to be a more effective method for improving the current maldistribution of healthcare providers.

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

Measuring Studentsâ Beliefs about Physics in Saudi Arabia  

Science.gov (United States)

Over the last decade, science education researchers in the US have studied students' beliefs about science and learning science and measured how these beliefs change in response to classroom instruction in science. In this paper, we present an Arabic version of the Colorado Learning Attitudes about Science Survey (CLASS) which was developed to measure students' beliefs about physics at King Saud University (KSU) in Riyadh, Saudi Arabia. We describe the translation process, which included review by four experts in physics and science education and ten student interviews to ensure that the statements remained valid after translation. We have administered the Arabic CLASS to over 300 students in introductory physics courses at KSU's men's and women's campuses. We present a summary of students' beliefs about physics at KSU and compare these results to similar students in the US.

Effects of Teaching Critical Thinking to Saudi Female University Students Using a Stand-Alone Course  

Directory of Open Access Journals (Sweden)

Full Text Available Teaching critical thinking, an educational goal widely discussed in the last 30 years (Halpern, 1993, is an essential element of professional and higher education as it promotes reasoned judgments under ‘conditions of uncertainty,’ a hallmark of professionalism (Levine, 2010; Shulman, 2005; Perry, 1970. In this study, the researchers present the implications of teaching CT in a course format in a Saudi private university that is preparing female professionals for the workforce. The course is taught as part of the general education requirements in the freshman year of study. Female students in the fields of business, computer sciences, and interior design participated in a CT pre-test /post-test sequence given at strategic times throughout the semester. The data illustrate significant improvement in the area of argument identification and analysis, but moderate to low improvement in the other markers of critical thinking. The results not only reflect course instruction as well as other external factors. The study suggests and recommends that in order for students to be critical thinkers, critical thinking would ideally be embedded or integrated throughout the students’ academic career, not just in one, stand-alone course.

Perceived Stress Scores among Saudi Students Entering Universities: A Prospective Study during the First Year of University Life  

Directory of Open Access Journals (Sweden)

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.

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.

Pattern of thyroid malignancy at a University Hospital in Western Saudi Arabia  

International Nuclear Information System (INIS)

The aim is to study the incidence of thyroid cancer in surgically treated nodular thyroid disease, clinicopathological characteristics and treatment results. A retrospective review of 45 patients with thyroid malignancy at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia during a 3-years period between January 2000 through to December 2003 was carried out. Analysis of clinicopathologic characteristics, age correlation to different risk factors, outcome of surgery and radioiodine treatment. A total of 120 thyroidectomies were performed during the 3-years period, January 2000 through to December 2003 at King Abdul-Aziz University Hospital. Forty-five (37.5%) patients had histopathology confirmed diagnosis of thyroid cancer. Eighty-two point two percent cases of papillary carcinoma, 4.4% follicular type and 6.7% anaplastic and medullary carcinoma of thyroid. Mean age was 40.5 +/- 14.8 years. Male preponderance was seen in this study with males: females ratio is 1.1:1. Nodular goiter was the most frequent presentation, observed in 30 (66.7%) cases. Fine needle aspiration cytology was suggestive of malignancy in 76% of cases. Ninety-seven patients with papillary carcinoma received ablative dose of radioiodine with average dose of 100-200 mCi. One female patient with follicular carcinoma of thyroid with bone, lung, and brain metastases received 4 doses of radioiodine with total dose of 800 mCi. Mortality rate was (2.2%), one patient died of complication of invasive anaplastic carcinoma with invasion of the trachea. There is a lot of controversy regarding thyroid malignancy investigations and management. We recommend that thyroid cancer patients should be treated by a team of endocrinologist, pathologist, experience thyroid surgeon, nuclear medicine and external radiotherapy physician to achieve an optimum care and good prognosis.

Hirsutism in Saudi females of reproductive age : A hospital-based study  

Directory of Open Access Journals (Sweden)

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.

Female University Students’ Physical Activity Levels and Associated Factors—A Cross-Sectional Study in Southwestern Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

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)

Directory of Open Access Journals (Sweden)

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

Standard Precautions and Infection Control, Medical Students' Knowledge and Behavior at a Saudi University: The Need for Change  

Directory of Open Access Journals (Sweden)

Full Text Available Background: No previous studies have reported the knowledge of Saudi medical students about Standard Precautions (SPs and infection control. Objectives: The objectives of this study were to assess medical students' knowledge in clinical years at King Faisal University, Saudi Arabia about SPs' and to explore their attitudes toward the current curricular/training in providing them with effective knowledge and necessary skills with regard to SPs. Subjects and Methods: This cross sectional study targeted students in clinical stage at College of Medicine, King Faisal University, Saudi Arabia. A pre-tested anonymous self administered data collection form was used. Inquires about students' characteristics, general concepts of infection control/SPs, hand hygiene, personal protective equipment, sharp injuries and disposal, and care of health providers were included. The main source of information for each domain was also inquired. The second part dedicated to explore the attitudes toward the curricular and teaching relevant to SPs. Results: A total of 251 students were included. Knowledge scores in all domains were considerably low, 67 (26.7% students scored ? 24 (out of 41points which was considered as an acceptable level of knowledge, 22.2% in 4th year, 20.5% in 5th year and 36.8% in 6th year. Sharp injuries, personal protective equipment and health care of the providers showed the least knowledge scores. The main sources of knowledge were self learning, and informal bed side practices The majority of students' believed that the current teaching and training are insufficient in providing them with the necessary knowledge and skills regarding SPs. Conclusion: The overall knowledge scores for SPs were low especially in the domains of hand hygiene, sharp management, and personal protective equipment reflecting insufficient and ineffective instructions received by medical students through the current curriculum posing them vulnerable to health facilities related infections. Proper curricular reform and training are required to protect students and their patients.

Perceptions of the educational environment of the medical school in King Abdul Aziz University,saudi Arabia.  

Science.gov (United States)

The present paper reports data from the undergraduate medical school at King Abdul Aziz University in Saudi Arabia using the 50-item Dundee Ready Education Environment Measure (DREEM), which has been validated and found to be reliable in a range of cultural contexts. The mean total score was 102/200. The mean total score for Perception of Learning was 22/48; for Perceptions of Teaching 24/44; for Academic Self-perceptions 17/32; for Perceptions of Atmosphere 23/48 and for Social Self Perceptions 15/28. The mean score of 0.9 for Item 3--There is a good support system for students who get stressed--was the lowest and is indicative of the pressures felt by the students. These scores give a clear indication of the priorities for reform of the curriculum. These data can also serve as a baseline for a longitudinal quality assessment of students' perceptions of the changes planned for the medical school at King Abdul Aziz University, Saudi Arabia. Further studies are needed to analyse educational environment down to the year levels and to detect any gender differences. PMID:15763838

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)

Bone mineral density and bone scintigraphy in adult Saudi female patients with Osteomalacia  

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)

Factors affecting the progression of diabetic nephropathy and its complications: A single-center experience in Saudi Arabia  

Science.gov (United States)

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 90 mL/min/1.73m2 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.

Determination of Prevalence of Strangles in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Strangles is one of the most important infectious diseases that affect the respiratory system of the horse. The disease is characterized by fever, nasal discharges and enlargement of the associated lymph nodes. Strptococcus equi the causative agent of strangles, is a Gram positive bacteria. The goal of this study is to determine the prevalence of strangles among horses residing on horse farms in main regions of the Kingdom of Saudi Arabia. To achieve this goal, field visits were made to horse farms in Al-Ahsa, Dammam, Jubail, Riyadh, Jeddah and Tayf. A total of 75 farms that contain 926 horses were visited. Farm owners and managers were questioned regarding the presence of signs similar to strangles. In the meantime, horses were clinically evaluated. This survey indicated no horses were strangles confirmed. Finally, 35 horses admitted to the Veterinary Teaching Hospital at King Faisal University were examined. These horses were admitted for signs of respiratory disorders. Physical and endoscopic examination as well as bacterial culture indicated they were strangles free. Strangles seems not to be a threat to horses in Saudi Arabia.

Allergic fungal sinusitis in children in Saudi Arabia  

International Nuclear Information System (INIS)

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

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)

Patterns of radiographic changes in hands and feet of rheumatoid arthritis in Saudi Arabia  

International Nuclear Information System (INIS)

The aim of the study was to characterize the pattern of radiographic changes in the hands and feet of rheumatoid arthritis in Saudi patients. The radiographs of hands and feet of rheumatoid arthritis patients attending rheumatology outpatient clinics of King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia, over the period extending from March to June 2001, were examined and reported for the presence of osteopenia, joint space narrowing, and erosions. Fifty-six rheumatoid arthritis patients were studied. Their mean age was 50 + 1.9 years, and mean disease duration was 9.07 + 0.84 years. Generalized osteopenia was seen in 16/56 (29%) and periarticular osteopenia in 38/56 (68%). Joint space narrowing was present in 9/56 (16%) of feet and 35/56 (63%) of hand x-rays. Erosions were seen in 3/56 (6%) of feet and in 22/56 (39%) of hand x-rays. Significant correlation was seen between joints space narrowing, joint erosions, and disease duration. Radiographic changes in hands and feet of Saudi rheumatoid arthritis patients are less severe than those reported from the West, and the pattern is also different with less affection of the feet.

Echocardiographic abnormalities in adolescent and adult Saudi patients with sickle cell disease  

International Nuclear Information System (INIS)

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 cancer and its risk and protective factors among women in Riyadh  

International Nuclear Information System (INIS)

We conducted this study to assess the knowledge of breast cancer and sources of information about breast cancer among women in Riyadh. We also analyzed whether associations existed between demographic variables. Knowledge of breast cancer and, and the practice of breast self examination and use of mammography screening. Women interested in participating in this community based descriptive study provided data by completing a pre-tested structured questionnaire. Of 864 participating women, 84% were Saudi 45% were married and 67.8% had a university level education*0% were between the ages of 20 to 50 years. 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)

Risk factors associated with postpartum depression in the Saudi population  

Directory of Open Access Journals (Sweden)

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

Investigating the Interaction Between Cognitive Complexity and Amount of L2 Exposure in Saudi College Students in the English Department at King Faisal University  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigated the relationship between Saudi EFL students writing competence and their Arabic writing proficiency. The study also examined the possible relationship between Saudi students' first language (Arabic and second language (English writing competence and their self-regulatory abilities. Participants included 35 college-level students majoring in English at King Faisal University. The participants wrote English and Arabic argumentative essays on the same topic during two separate sessions. The collected data were used to compare and contrast the participants writing competence in Arabic and English. The study showed a strong correlation between L2 (English writing competence and L1 (Arabic writing proficiency. Saudi students who scored high in L1/L2 writing had high self-regulation abilities. Furthermore, the study revealed a strong-to-medium correlation between students L1/L2 writing competence and their self-regulation abilities, as measured by the two factors of the MAI (knowledge of cognition and regulation of cognition. Therefore, the study suggests that EFL instructors in Saudi Arabia should focus more on these factors when planning their writing curriculum and instruction. The study also recommends that L1/L2 writing instruction should help students build proper writing schemata and regulate their writing processes. In addition, the results of this study can help language teachers in Saudi Arabia understand the extent and effectiveness of Saudi students use of self-regulation processes to help them acquire English and Arabic language skills. Also, the planners at the Ministry of Education can benefit from the results of this study to design integrative texts that treat writing skill in Arabic as interrelated with English writing skill.

Science.gov (United States)

Background: Medical education & medical profession are among the most challenging and most stressful ones. Anxiety and depression represents an escalating public health problem among medical students. The objective of the study was to determine the prevalence & predictors of anxiety and depression among female medical students in King Abdulaziz University, Jeddah, Saudi Arabia. Methods: A cross-sectional study was carried out during 2010–2011. A stratified random sample method was used to select 450 medical students. A confidential, anonymous & self administered questionnaire included Standardized Hospital Anxiety & Depression Scale was used. Results: The mean scores for anxiety and depression were 9.32 ± 3.77 & 6.59 ± 3.62, respectively. There is a positive correlation between anxiety & depression scores (r= 0.52, P< 0.001). Prevalence of morbid anxiety and depression were 34.9% and 14.7%, respectively. Logistic regression analysis revealed that the first predictor of morbid anxiety was depression (adjusted Odds Ratio (aOR) = 3.28; 95% Confidence Interval (CI): 1.85–5.82, P < 0.001). Students complained from condensed academic course, had academic and emotional failures during the 6 months preceded the study were about 2 times more prone to anxiety. Predictors of depression were having anxiety, nationality (being non-Saudi) & having emotional failure. Conclusion: Medical students encountered high rates of anxiety & depression compared to others. Academic problems and major life events were the main predictors. Enhancing faculty preventive & curative mental health services is recommended. Initiation of stress management courses & enhancing academic advising services are required since the start of medical education.

Eruption time of permanent first molars and incisors among female primary school children of riyadh  

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)

Clinico-pathological patterns of colorectal cancer in Saudi Arabia: Younger with an advanced stage presentation  

Directory of Open Access Journals (Sweden)

Full Text Available Aim: Colorectal cancer (CRC is the third most common cancer in the world. The aim of this study was to identify the clinical and pathological features of CRC in a tertiary care hospital in Saudi Arabia. Materials and Methods: This is a retrospective study of all patients diagnosed to have CRC at King Khalid University Hospital in Riyadh, Saudi Arabia over a 10 year period (1995-2005. The data collected from medical files, endoscopy and imaging reports included age, gender, clinical presentation, smoking, relevant past or family history, site and size of the tumor, stage, carcinoembryonic antigen level and tumor grade. Results: A total of 113 patients were included over the 10 year period. The average age at diagnosis was 55 years (S.D.=15, 58% of the patients were males and 42% were females. Thirty-seven percent of the patients were 50 years of age or younger. The most common clinical presentation was abdominal pain (68% followed by rectal bleeding (62% and weight loss (55%. Left-sided lesions and rectal cancer constituted 76% and 48% of all CRC tumors respectively. Sixty-eight percent of lesions were stage C and above. Forty-five percent of patients presented with complete large bowel obstruction. Conclusion: In this analysis, we found that Saudi patients were more likely to present with colorectal cancer at a more advanced stage of the disease and at younger ages compared to Western populations. This data suggests the need for a mass screening program to be implemented for this common and preventable cancer in Saudi Arabia.

Quality of life in patients with skin diseases in central Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Mostafa A Abolfotouh,1 Mohammad S Al-Khowailed,1 Wijdan E Suliman,1 Deema A Al-Turaif,1 Eman Al-Bluwi,2 Hassan S Al-Kahtani21King Abdullah International Medical Research Center, King Saud Bin-Abdulaziz University for Health Sciences, 2Dermatology Department, King Abdulaziz Medical City, Riyadh, Kingdom of Saudi ArabiaBackground: Previous national and international studies of quality of life (QoL in patients with skin diseases have revealed different levels of QoL impairment. 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

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)

A prospective study of congenital malformations among live born neonates at a University Hospital in Western Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to estimate the incidence of major and minor congenital malformations among live born infants at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Estimation of risk factors was also evaluated. Between March 2004 and May 2005, a total of 5356 babies born at King Abdulaziz University Hospital, were enrolled in this study for malformations. Details of cases were recorded after parent's interviews, clinical, radiological and laboratory evaluations. One hundred and forty-seven (27.06/1000 livebirth) and 13 (2.39/1000 birth) stillbirth have congenital anomalies. In all livebirth, incidences of major anomalies were 93.9% and minor were 6.1%. Mothers of 95.9% with congenital malformation were healthy, 3.4% were diabetic and 0.7% had cardiac malformation. In 38.8% of cases parents were consanguineous. Among the liveborn births, the most common system involved was cardiovascular (7.1/1000), followed by musculoskeletal/limb (4.1/1000), external genitilia (2.8/1000), urinary (2.6/1000),multiple chromosomal (2.2/1000), orofacial (1.9/1000), central nervous system (1.9/1000), skin (1.7/1000), multiple single gene (1.3/1000), multiple sequence (0.75/1000), eyes (0.56/1000), unclassified (0.19/1000), musculoskeletal/abdominal (0.19/1000), endocrine (0.19/1000). High incidence of major malformation was found in Jeddah. Importance of Genetic Counseling is revealed in our study since more than three quarters of mothers were under 36 years and may well plan future pregnancies. (author)

Drivers' behaviour at roundabouts in Riyadh.  

Science.gov (United States)

As is the case in many cities, roundabouts are used extensively in Riyadh. However, instead of improving safety, driving through roundabouts in Riyadh can be a dangerous experience as many drivers do not follow regulations. Unfortunately, no official statistics exist on accidents or violations at roundabouts and no studies have been done to assess this problem. A field study to collect data on drivers' behaviour at five roundabouts in Riyadh was done and a questionnaire was randomly distributed to drivers to explore this issue. Results showed that the percentage of drivers breaching at least one traffic regulation is approximately 90% of all drivers driving through these roundabouts, with leaving without flashing and entering the roundabout without giving way being the most frequent violation types. Questionnaire results from 384 respondents showed that there is a lack of information among most drivers on roundabout driving regulations and that driver training and licensing process does not include enough information related to this matter. Finally, practical suggestions as how to tackle this issue in terms of education, training and policing are given. PMID:21660796

Full Text Available A El-Ansary1, S Al-Daihan1, A Al-Dabas1, L Al-Ayadhi21Biochemistry Department, Science College, 2Autism Research and Treatment Unit, Department of Physiology, Faculty of Medicine, King Saud University, Riyadh, Saudi ArabiaObjective: Measurement of plasma levels of lactate, lactate oxidase (LOX, pyruvate kinase (PK, and hexokinase (HK as possible glycolytic parameters to assess brain damage in autistic patients.Design and methods: Plasmatic levels of lactate, LOX, PK, and HK were determined in 20 autistic children aged 3–15 years and 20 age-matching healthy control subjects.Results: Plasmatic levels of lactate and LOX were significantly higher in autistic patients compared to healthy subjects and that of PK and HK were significantly lower in these patients as compared to controls. This could reflect the impaired metabolism of astrocytes, the brain cells responsible for the production and provision of lactate, as the primary metabolic fuel for neurons.Conclusion: Remarkably different levels of plasma glycolytic parameters were recorded in Saudi autistic patients. This could be correlated to the impairment of energy metabolism, glutathione depletion, and lead intoxication previously detected in the same investigated samples. The identification of biochemical markers related to autism would be advantageous for earlier clinical diagnosis and intervention.Keywords: autism, glycolysis, lactate, lactate oxidase, pyruvate kinase, hexokinase

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).

Faculty Perception of Stress and Coping Strategies in a Saudi Private University: An Exploratory Study  

Directory of Open Access Journals (Sweden)

Full Text Available Teaching profession was once viewed as a ‘low stress occupation’ and they have been envied for tenure, light workloads, flexibility and other perks such as foreign trips for study and conference. However, some recent studies suggest that university faculty is among the most stressed occupational group. The present study was conducted to explore the faculty perception towards occupational stress using established questionnaire, data collected from five departments in the private university. Research findings on the coping strategies that faculty used to tackle stress were also reviewed. Through this study, it is suggested that the top management and University Administration should focus their attention on faculty stress, especially on two areas (student Interactions and Professional Identity to reduce the stress among the faculty members. Care should be taken to make even remote faculty feel a part of the greater whole of this institution thorough regular communication and support.

A Comparative Study of Perceived Stress among Female Medical and Non-Medical University Students in Dammam, Saudi Arabia  

Science.gov (United States)

Objectives The objective of this study was to investigate any differences between female undergraduate medical and non-medical students for: 1) prevalence and causes of perceived academic stress, and 2) changes in physical, mental, psychological and emotional health as well as life-style since starting college studies. Methods A cross-sectional study was conducted at Dammam University, Dammam, Saudi Arabia, in January 2008. All 319 pre-clinical female medical students were included in the study and 297 non-medical students from the College of Applied Studies and Community Services (CASCS) were selected by stratified random sampling. The study instrument was a questionnaire on the “Influence of Studying on Students’ Health”. Results More medical students (48.6%) reported being frequently stressed due to studies than CASCS students (38.7%, P <0.01). Unsuitable teaching methods, an unsatisfactory study environment, and fear of failure in examinations were more frequently mentioned by medical than non-medical students (P <0.05). While underlying social problems were significantly more common in medical students, economic problems were more prevalent among CASCS students (P <0.05, P <0.05). More medical than non-medical students reported a worse status of physical and mental health, anxiety and depression and negative life-style changes since initiation of the college programme. Conclusion Medical students were at higher risk of physical and mental health problems than non-medical students due to academic stress. Since a substantial proportion of CASCS students also experienced academic stress, we recommend that a student support committee be established for both colleges to provide counselling and guidance in healthy ways to cope with stress.

Crystal chemistry and Moessbauer spectroscopic analysis of clays around Riyadh for brick industry  

Energy Technology Data Exchange (ETDEWEB)

A total of 30 clay samples were collected from the area around Riyadh city, Saudi Arabia. A complete chemical analysis was carried out using different techniques. X-ray diffraction studies showed that the clay samples were mainly of the smectite group with traces of the kaolinite one. The samples studied were classified as nontronite clay minerals. One of the clay fraction has been studied by Moessbauer spectroscopy as raw clay fraction and after being fired at 950-1,000 Degree-Sign C. The Moessbauer spectra showed accessory iron compounds in the form of hematite and goethite. The structural iron contents disintegrate on firing transforming into magnetic iron oxide and a paramagnetic small particles iron oxide.

Measurements of natural and man-made radioactivities in the soil in Riyadh region  

International Nuclear Information System (INIS)

Measurement of concentrations of naturally occurring radionuclides together with some man-made deposited ones in soil have been carried out in Riyadh region of the Kingdom of Saudi Arabia. Soil samples from more than one hundred locations have been studied. Concentration of gamma emitting radionuclides from both uranium and thorium series, 40K and 137Cs have been measured using hyper pure germanium spectrometers. Concentrations of 238U in soil samples have been evaluated using laser fluorimetry, while 90Sr has been measured after chemical separation using a liquid scintillation counter. Gamma-ray doses have been measured in the same sites where soil samples were collected and the measured values are given together with calculated doses based on the measured concentrations of natural gamma emitters in soil

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

Science.gov (United States)

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.

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)

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)

Directory of Open Access Journals (Sweden)

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.

Thermal comfort requirements in hot dry regions with special reference to Riyadh Part 2: for Friday prayer  

Energy Technology Data Exchange (ETDEWEB)

This study is an attempt to define thermal comfort requirements for Friday prayer during the hot season of Riyadh, Saudi Arabia. According to Islam, a Muslim should perform his prayers five times a day. The obligatory five prayers are Subuh prayer immediately before dawn, Thohor prayer in the afternoon, Assor prayer in late afternoon, Maghreb prayer immediately after sunset, and Ishaa prayer early evening. Generally, Muslims are encouraged to perform all five prayers in a mosque. Friday prayer that replaces Thohor prayer once a week, should take place in one of the main mosques of the neighbourhood. The mosque where Friday prayer could be performed is known as Friday mosque. Usually Friday prayer is attended by hundreds of worshippers and takes place in the afternoon. Since the summer of Riyadh is characterised by a very high temperature and a very low relative humidity, the indoor climate of the Friday mosque (Al-Masjed Al-Gamae) need a special study. This is the second part of a series of field investigations dealing with thermal comfort requirements in the hot-dry region of Saudi Arabia. (author)

Science.gov (United States)

Background This study describes epidemiological data of non-Hodgkin’s lymphoma (NHL) diagnosed from 2001 to 2008 among Saudi men. Materials and methods Retrospective data from all NHL cancer cases among Saudi men recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008 were used. Descriptive statistics, analysis of variance, Poisson regression, and simple linear regression were also used. Results In total, 2,555 new cases of NHL were recorded between January 2001 and December 2008. The region of Riyadh, Saudi Arabia had the highest overall age-standardized incidence rate (ASIR) at 7.8, followed by the Eastern region at 6.8, and Makkah at 6.1 per 100,000 men; however, Jazan, Hail, and Baha had the lowest average ASIRs at 2.5, 3.7, and 3.9 per 100,000 men, respectively. The incidence-rate ratio for the number of NHL cases was significantly higher in Riyadh (4.68, 95% confidence interval [CI] 4.11–5.32), followed by Makkah (4.47, 95% CI 3.94–5.07), and the Eastern region of Saudi Arabia (3.27, 95% CI 2.90–3.69) than that in the reference region of Jazan. Jouf had the highest changes in the ASIRs of NHL among Saudi men from 2001 and 2008 (5.0 per 100,000 men). Conclusion A significant increase in the crude incidence rate and ASIR for NHL in Saudi Arabia between 2001 and 2008 was found. Riyadh, the Eastern region, and Makkah had the highest overall ASIR in Saudi Arabia. Jazan, Hail, and Baha had the lowest rates. Additionally, Riyadh, Makkah, and the Eastern region had the highest incidence-rate ratio for the number of NHL cases. Finally, Jouf had the highest changes in crude incidence rate and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of NHL among Saudi men.

Proteinuria in adult Saudi patients with sickle cell disease is not associated with identifiable risk factors  

Directory of Open Access Journals (Sweden)

Full Text Available Renal involvement in patients with sickle cell disease (SCD is associated with signi-ficant morbidity and mortality. Proteinuria is common in patients with SCD and is a risk factor for future development of renal failure. We sought to identify risk factors, if any, associated with pro-teinuria in adult Saudi patients with SCD. We studied 67 patients with SCD followed-up at the King Khalid University Hospital, Riyadh, Saudi Arabia. All patients underwent 24-hour urine collection to measure creatinine clearance and to quantify proteinuria. In addition, blood was examined for evaluation of hematological and biochemical parameters. Clinical information was gathered from review of the patients? charts. A urine protein level of more than 0.150 grams/24 hours was consi-dered abnormal. Urine protein was correlated with various clinical and laboratory parameters. Thirty-one males and 36 females were evaluated. The mean age of the cohort was 23.8 (± 7.2 years. Twenty-seven patients (40.3% had proteinuria of more than 0.150 grams/24 hours. The study group had a mean hemoglobin level of 8.5 (± 2.8 g/dL and mean fetal hemoglobin (HbF level of 14.4% (± 7.3%. Majority of the patients (61 had hemoglobin SS genotype and six patients had S-?0 thala-ssemia. None of the parameters evaluated correlated with proteinuria although there was a border-line association with older age and higher systolic blood pressure (P = 0.073 and 0.061 respec-tively. Hydroxyurea use for more than a year was not beneficial. In conclusion, our study suggests that proteinuria in adult Saudi patients is not associated with any clear identifiable risk factors.

International Nuclear Information System (INIS)

The spatial variation of radon concentration within the building of the preparatory year located in Riyadh was studied. Nuclear track detectors (CR-39) were used to measure radon concentration for two consecutive six month periods in more than 40 rooms of the surveyed building. Coefficient of variation (CV) was calculated as a measure of relative variation of radon concentration between floors and between rooms on the same floor. Floor mean ratios, with ground floor as a reference level, were calculated also in order to study the correlation between radon concentration and floor levels in case of using advanced Italian granite building material. All the results of this study were investigated and compared with usual Indian granite building material and it was found that the knowledgement buildingis a healthy work place which may be due to uses of advanced building materials.

Directory of Open Access Journals (Sweden)

Full Text Available Nasreldin Elhadi,1 Reem Aljindan,2 Mohammed Aljeldah11Department of Clinical Laboratory Science, College of Applied Medical Sciences, 2Department of Microbiology, College of Medicine, University of Dammam, Dammam, Saudi ArabiaBackground: Nontyphoidal Salmonella (NTS species are important food-borne pathogens that cause gastroenteritis and bacteremia, and are responsible for a huge global burden of morbidity and mortality. The aim of this study was to investigate the prevalent serogroups and antibiotic resistance of NTS in our region.Methods: We reviewed the serogroup distribution and antimicrobial susceptibility patterns of NTS strains obtained from 158 stool specimens of patients with acute diarrheal infection attending the outpatient and inpatient department at a university hospital in the Eastern Province of Saudi Arabia in the period from September, 2008 to April, 2011. A retrospective analysis of the 158 patients with NTS infection was conducted to determine the most prevalent NTS serogroups causing acute gastroenteritis and their antimicrobial susceptibility patterns.Results: At this teaching hospital, a total of 17,436 fecal samples were analyzed during the 2008–2011 study period. Of these specimens, 158 tested positive for NTS, giving an overall prevalence of 9.06 per 1,000. Of 158 NTS cases, serogroup D1 (25.3% was the most prevalent, followed by serogroup B (19.6%, and serogroup C1 (18.9. One third of all NTS serogroup strains tested were resistant to tetracycline. The NTS strains showed resistance to ampicillin (31.3%, amoxicillin/clavulanic acid (29.9%, trimethoprim/sulfamethoxazole (20.9%, and cefotaxime (14.93%.Conclusion: The findings of this study support the concern that use of antibiotics in animal feeds may contribute to acquisition of resistance in food-borne bacteria, such as Salmonella. Our study also concludes that the prevalence of NTS in the Eastern Province of Saudi Arabia is very low compared with other studies worldwide.Keywords: nontyphoidal Salmonella, serogroups, prevalence, antimicrobial resistance, Saudi Arabia

Incidence rate of ovarian cancer cases in Saudi Arabia: an observational descriptive epidemiological analysis of data from Saudi Cancer Registry 2001-2008  

Science.gov (United States)

Purpose This study provides descriptive epidemiological data, such as the percentage of cases diagnosed, crude incidence rate (CIR), and age-standardized incidence rate (ASIR) of ovarian cancer in Saudi Arabia from 2001–2008. Patients and methods A retrospective descriptive epidemiological analysis of all ovarian cancer cases recorded in the Saudi Cancer Registry (SCR) from January 2001–December 2008 was performed. The data were analyzed using descriptive statistics, analysis of variance tests, Poisson regression, and simple linear modeling. Results A total of 991 ovarian cancer cases were recorded in the SCR from January 2001–December 2008. The region of Riyadh had the highest overall ASIR at 3.3 cases per 100,000 women, followed by the Jouf and Asir regions at 3.13 and 2.96 cases per 100,000 women. However, Hail and Jazan had the lowest rates at 1.4 and 0.6 cases per 100,000 women, respectively. Compared to Jazan, the incidence rate ratio for the number of ovarian cancer cases was significantly higher (PSaudi Arabia at 4.52 (95% CI: 2.93–6.98). The predicted annual CIR and ASIR for ovarian cancer in Saudi Arabia could be defined by the equations 0.9 + (0.07× years) and 1.71 + (0.09× years), respectively. Conclusion We observed a slight increase in the CIRs and ASIRs for ovarian cancer in Saudi Arabia from 2001–2008. Riyadh, Jouf, and Asir had the highest overall ASIR, while Jazan and Hail had the lowest rates. Makkah, Riyadh, and the eastern region of Saudi Arabia had the highest incidence rate ratio for the number of ovarian cancer cases. Further analytical studies are required to determine the potential risk factors of ovarian cancer among Saudi women.

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.

Saudi Arabia: perspective on oil, foreign policy, and the Arab-Israeli conflict, 1970-1980  

Energy Technology Data Exchange (ETDEWEB)

This study examines, through a descriptive and analytical approach, the Saudi perspective on its oil power and policies in world affairs and how the Arab-Israeli conflict affects these policies. A special emphasis on the United States-Saudi Arabian relationship is made, since Saudi Arabia looks at the United States as the key factor in the Arab-Israeli conflict. To serve this end, the dissertation is divided into three parts. Part one examines the economic and political reality of oil power, its implication and limitation. Also, this part examines the behavior and the policies of the oil companies, the oil-consuming countries, and the oil-producing countries after the structural change of the oil industry and the shift in control of production and prices from the hands of the oil companies to those of the oil-producing countries. Part two examines the Saudi Arabian economy, the role of oil in developing this economy, and the effect of Saudi development plans on Saudi oil policies. Part three examines Saudi foreign policy, especially its role in the Arab-Israeli conflict, with emphasis on the Saudi oil role in this regard. Also, this part examines the United States-Saudi Arabia relationship and interest, the United States interest in Israel, and, finally, how Riyadh sees these interests affecting United States policies in the Middle East.

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

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)

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.

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.

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)

A clinical study of mentally retarded children with fragile X syndrome inSaudi Arabia  

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%). The study showed that the fragile Xsyndrome clinical screening checklist has been applied in other populationsmight equally valuable and applicable among the population of Saudi Arabia.However, the presence of pale blue eyes can be excluded and more weight givento positive family history of mental to the most common clinical diagnosticfeatures of fragile X syndrome.

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)

Directory of Open Access Journals (Sweden)

Full Text Available The aim of the study was to determine surgical indication and complication of subtotal thyroidectomy in patients being treated for Graves` disease at King Khalid University Hospital Riyadh Saudi Arabia in the period between January 1996 and December 2005. Twenty-five out of 194 adult patients with Graves` disease had thyroidectomy for hyperthyroidism during the 10-year period representing 13% comprising 11 males and 14 females. Mean age at presentation for all the patients was 28?12 years. Males had higher serum T4 77.7?20.7 than females 49.8?21.9 pmol L-1; p<0.05. Serum T3 levels were similar in both groups 31.9?15.2 for males and 29.4?15.7 pmol L-1 for females, p = NS. Failure of antithyroid and/or radioiodine along with severe ophthalmopathy (52%, patient preference (12% and large goiter alone (8% were major indications for thyroidectomy in this group. Permanent remission occurred in 15 patients (60% following the surgery. Hypothyroidism and relapse were observed in 16 (64% and 4 (16% of patients, respectively. One patient (4% each experienced permanent recurrent laryngeal nerve palsy and hypoparathyroidism. It was concluded that more males than females with severe hyperthyroidism had thyroidectomy and that failure of antithyroid/radioiodine treatment and severe ophthalmopathy were the commonest indications for surgery in patients in patients with Graves` disease while post surgical permanent hypoparathyroidism and recurrent laryngeal nerve palsy were uncommon.

The Histological Spectrum of Early Mycosis Fungoides: A Study of 58 Saudi Arab patients  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: The histopathological diagnosis of Mycosis Fungoides (MF is challenging in its early stages and can easily be confused with inflammatory dermatoses. This study aims to; (i assessthe frequency and significance of different histopathological parameters in early MF, seen in Saudi patients, and (ii to studythe utility of these parameters in differentiating between early MF and inflammatory dermatoses.Methods: This is a five years study of 66 skin biopsies generated from 58 patients with clinically suspicious MF lesions or early patch stage MF. These cases were retrieved from the archives ofthe Department of Pathology, King Khalid University Hospital, Riyadh from the year 2002 to 2006. Histological criteria were assessed and graded semi-quantitatively on a four-point scale by adermatopathologist and two pathologists independently.Results: The histological parameters suggesting the diagnosis in early stages MF include epidermotropism, dermal fibrosis, Pautrier’s micro abscesses, Basal alignment of neoplastic lymphocytes, hyperconvoluted dermal and epidermal lymphocytes and grandiosity sign (size of lymphocytes becoming larger as they migrate towards granular layer of epidermis. These parameters on univariate analysis achieved statistical significance (p<0.05 in differentiating MF from non-MF cases. In addition, hyperconvoluted dermal and epidermal lymphocytes proved to be highly reliable with high specificity and sensitivity.Conclusion: The histopathological diagnosis of early MF lesions and their discrimination from inflammatory simulators can be achieved by carefully observing the hyperconvoluted dermal and epidermal lymphocytes along with the constellation of the other parameters.

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)

Prevalence and Characteristics of Colonic Polyps and Adenomas in 2654 Colonoscopies in Saudi Arabia  

Science.gov (United States)

Background/Aims: Colorectal cancer (CRC) is the second most common malignancy in the Saudi population, with an increasing incidence over the past 20 years. We aim to determine the baseline polyp as well as adenoma prevalence in a large cohort of patients and to find the possible age in which, if deemed appropriate, a CRC screening program should be initiated. Patients and Methods: A retrospective cohort study was conducted using an endoscopic reporting database of individuals seen at a major tertiary care university hospital (King Khalid University Hospital) in Riyadh, Saudi Arabia. Consecutive Saudi patients who underwent a colonoscopy between August 2007 and April 2012 were included. Patients were excluded if the indication for the colonoscopy was colon cancer, colonic resection, active colitis, active diverticulitis, inflammatory bowel disease, or if the patient was referred for polypectomy. Results: 2654 colonoscopies were included in the study. The mean age of the study population was 50.5 years [standard deviation (SD) 15.9] and females represented 57.7%. The polyp detection rate in completed colonoscopies was 20.8% (95% CI: 19.2-22.5). Adenomas were found in 8.1% (95% CI: 7.1-9.1), while advanced adenomas were found in only 0.5% (95% CI: 0.2-0.7). Adenomas were found in the left side of the colon in 33.9%, followed by the rectum in 14.6%, ascending colon and cecum in 14.2%, transverse colon in 8.7%, and in multiple locations in 28.7%. Those with a prior history of polyps or CRC were more likely to have an adenoma at colonoscopy than those who did not (14.3% vs. 6.6%; P < 0.01). The adenoma prevalence varied between age groups and ranged from 6.2% to 13.6% with a higher proportion in older individuals; this trend was seen both in males (6.0-14.5%) and females (6.4-14.6%) as well as in those who had screening colonoscopies (6.3-18.4%). No age could be found at which a CRC screening program would be appropriate to initiate. Conclusion: The prevalence of polyps and adenomas in this cohort is less than that reported in the Western populations. But as this cohort included younger and symptomatic patients with only a small proportion undergoing screening, further studies in an asymptomatic population are needed.

The incidence rate of corpus uteri cancer among females in Saudi Arabia: an observational descriptive epidemiological analysis of data from Saudi Cancer Registry 2001-2008  

Science.gov (United States)

Background The present study reviews the epidemiological data on corpus uteri cancer among Saudi women, including its frequency, crude incidence rate, and age-standardized incidence rate (ASIR), adjusted by region and year of diagnosis. Methods A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0), followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0), and the eastern region, at 9.9 times (95% CI: 5.6–17.6). The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease. Riyadh, the eastern region, and Makkah had the highest overall disease ASIRs and incidence rate ratios, while Jazan, Najran, and Qassim had the lowest rates. Finally, the northern region experienced the greatest changes in ASIR during the studied period. Further analytical studies are necessary to determine potential risk factors of corpus uteri cancer among female Saudi patients.

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)

Prevalence of glucose-6-phosphate dehydrogenase deficiency and sickle cell trait among blood donors in Riyadh  

Science.gov (United States)

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.

Factors affecting the progression of diabetic nephropathy and its complications: A single-center experience in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

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)

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this paper is to assess the scope, development, and future of Institutional Repositories (IR in Saudi Arabia. This paper is based on the authors’ working experience at King Saud University Dspace repository project. To ensure the number of repository projects in Saudi Arabia the directory of open access repositories, (Open DOAR, Registry of Open Access Repositories (ROAR, and the websites of the existing universities in the Kingdom of Saudi Arabia has been browsed. There is a general lack of awareness with regard to Open Institutional Repositories in Saudi Universities and higher education institutions. Only four Universities i.e. King Saud University (KSU, King Fahd University of Petroleum & Minerals, Umm Al-Qura University, and University of Dammam have taken some initiatives in this regard. Though these universities have made commendable efforts there still lots of improvements and developments required with regard to Institutional Repositories. It is expected that this paper will encourage Saudi Academic organizations to take the initiatives in the development of open institutional repositories. No such study (Research type, Essay, View point has been conducted so far in the context of Saudi Arabia.

A Prospective Study of Renal Biopsies Performed Over One-year at the Riyadh Armed Forces Hospital  

Directory of Open Access Journals (Sweden)

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.

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.

Sixty known cases of CAD who had undergone angiography (35 males and 25 females were selected. A control group included 39 (20 males and 19 females healthy subjects. Fasting venous blood samples were analyzed for total (TFPI-T and free (TFPI-F tissue factor pathway inhibitor, plasminogen activator inhibitor-1 (PAI-1, and tissue plasminogen activator (t-PA. Gensini scores and vessel scores were determined for assessing CAD severity.Results: There were non-significant differences between age, body mass index (BMI and Blood pressure between the controls and CAD subjects. A comparison of hemostatic markers between control and CAD patients showed significantly higher levels of Fibrinogen, PAI-1, TFPI-T and TFPI-F in CAD patients compared to control subjects. But there was no difference in plasma t-PA levels. TFPI-T had a significant positive correlation with severity of disease determined by Gensini Scores (r=0.344; p=0.006 and vessel scores (r=0.338; p=0.015.Conclusion: Plasma levels of total tissue factor pathway inhibitor are significantly related with the presence and severity of CAD. Elevated levels of TFPI-T may be considered as useful diagnostic and prognostic markers in patients with CAD.

Distribution of Serotypes and Antibiotic Susceptibility Patterns Among Invasive Pneumococcal Diseases in Saudi Arabia  

Science.gov (United States)

Background Streptococcus pneumoniae causes life-threatening infections such as meningitis, pneumonia, and febrile bacteremia, particularly in young children. The increasing number of drug-resistant isolates has highlighted the necessity for intervening and controlling disease. To achieve this, information is needed on serotype distribution and patterns of antibiotic resistance in children. Methods All cases of invasive pneumococcal disease (IPD) in children aged less than 15 yr recorded at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, were reviewed for serotyping and antibiotic susceptibility. Isolates were collected from 78 consecutive patients with IPD between 2009 and 2012. All collected isolates were subjected to serotyping by co-agglutination, sequential multiplex PCR, and single PCR sequetyping as previously described. Results The most frequently isolated IPD serotypes were 23F, 6B, 19F, 18C, 4, 14, and 19A, which are listed in decreasing order and cover 77% of total isolates. The serotype coverage for the pneumococcal conjugate vaccine (PCV)7, PCV10, and PCV13 was 77%, 81%, and 90%, respectively. Results from sequential multiplex PCR agreed with co-agglutination results. All serotypes could not be correctly identified using single PCR sequetyping. Minimum inhibitory concentration showed that 50 (64%) isolates were susceptible to penicillin, whereas 70 (90%) isolates were susceptible to cefotaxime. Conclusions The most common pneumococcal serotypes occur with frequencies similar to those found in countries where the PCV has been introduced. The most common serotypes in this study are included in the PCVs. Addition of 23A and 15 to the vaccine would improve the PCV performance in IPD prevention.

Full Text Available Background: Energy drinks are freely available at markets and shops on the university campus without regulation or proper education regarding its side effects. The caffeine amount within energy drinks is high and could become an addictive substance or cause intoxication. Therefore, this study aims to assess the prevalence of energy drink consumption and its reported side effects among medical students. Methods:A total number of 257 medical students from Umm Al-Qura University completed a questionnaire about energy drinks that was administrated electronically from September through November, 2012. Results:Out of the 257 participants, 27.2% (n=70 reported consuming at least one energy drink per month, with 61.5% (n=48 being males. Males consume significantly more energy drinks than females (p=0.0001. The students consumed energy drinks to get energy in general (32.8% and while studying for exams or finishing a project (31.4%. Other reasons given include, lack of sleep (12.8%, just to be like friends (11.4%, or driving (8.5%. Heart palpitations are the most common side effect in our sample (20%, followed by insomnia (10%, headache and tremors (5.7%, nausea and vomiting (4.2% and nervousness (2.8%. Conclusion: Energy drinks consumption is common practice among medical students and the main reason cited for consumption is the need for energy during general activities. Approximately one-third of the consumers manifested some side effect after consumption. We recommend the need to create public awareness about energy drinks. Further studies are recommended to assess the educational level of students consuming energy drinks, about the dangerous side effects.

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

Directory of Open Access Journals (Sweden)

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

Hypertension Control and co-morbidities in primary health care centers in Riyadh  

International Nuclear Information System (INIS)

The prevalence of hypertension in Saudi Arabia has been assessed only in preliminary reports. The aim of this study was to determine the degree of control of blood pressure and the prevalence of common hypertension co-morbidities among hypertensive patients attending primary health care (PHC) centers in Riyadh. A cross sectional study was conducted by reviewing medical records of hypertensive patients during May and June 2001. Two hundred fifty-five medical records selected by a stratified randomization process according to the distribution of the 73 PHC centers in the city and the total number of hypertensive patients registered in the mini-clinic of each PHC-center. Trained mini-clinic nurses collected data using a data collection form developed for this purpose. Of 255 patients, 121 (47.5%) were males and 134 (52.5%) were females, the mean age was 57.2+-11.1 years and 8.3% were smokers. The majority 204 (85.7%) had greater than normal body weight. Only 101 (40.4%) had controlled systolic BP. The most common co-morbidity was diabetes mellitus found in 98 (38.4%), followed by dislipidemia in 50 (19.6%), bronchial asthma in 28 (11.0%) and renal diseases in 12 (4.7%). Except for osteoporosis, which was reported by females only (P=0.003), the occurrences of hypertensive co-morbidities did not vary from other demographic characteristics. This study demonstrated poor blood pressure control in the mini-clinics in the PHC-centers. To improve the quality of care for hypertensive patients, we recommend an improvement in PHC physician knowledge of and attitudes toward the importance of achieving targeted blood pressure levels.

This is the first time the concept of total quality management in burn injuries is proposed. This is a prospective study done in 1997-2003. All burn admissions to King Fahd Hospital of the University, Division of Plastic Surgery, were included. Total number of cases is 240. Male patients constituted 141 (59.2%); female patients, 97 (40.8%), and 2 cases were not specified in forms. There were 114 children (0-18 years, 50.2%) and 113 adults (19-99 years, 49.8%). The source of admission was mainly emergency room (197, 82%) followed by outpatient department (27, 11.3%), and other hospitals in 16 (6.7%). The type of burn was mainly scald (16.3%), then flame (6.98%), electrical (6.5%), chemical (2.8%), friction (0.47%), and not specified in 33% of recorded cases. The most encountered body percentage burn was 1% to 10% and 11% to 20% in 36.7% and 25.9% of cases, respectively. Sixty-six cases (28.2%) were operated on. The reason for nonoperation was not indicated in 78.5% and refusal in 1.8%. The most frequent operation was split-thickness skin grafting followed by tangential excision + split-thickness skin grafting. Operations took mostly about 2 hours (53.8%). The region operated on was mainly upper limbs (42.6%), then head and neck (27.7%). The affected body part in electrical burns was upper limb, then the head. Preoperative photography was done in 17% and post operatively in 9.4% of recorded cases. Consultations were needed in 39.4% and responded to in 48 hours in 98.2% of them. Discharge was home in 80.9%, against medical advice in 7.5%, died in 7%, transferred in 4%, and other ward in 0.5%. No significant difference was observed between pediatric age groups and adults (>18 years old), also for electrical versus nonelectrical burns in relation to total hospital stay. Similar observations were made among various age groups with respect to total hospital stay. The clinicopathologic typing relation to age groups, nationality, and sex was found significant. Recommendations and the newly proposed zone of practice and concept of total quality management in burn injuries are included. PMID:21403564

Prevalence of glucose-6-phosphate dehydrogenase deficiency and sickle cell trait among blood donors in Riyadh  

Directory of Open Access Journals (Sweden)

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.

Glomerulonephritis in Saudi Arabia: A Review  

Directory of Open Access Journals (Sweden)

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%.

Clinico pathological pattern of malignant parotid gland tumors in Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to report our experience of varied presentations and diverse histopathological spectrum of parotid gland malignancies. This retrospective analysis incorporated patients with histological evidence of malignant parotid tumors at King Khalid University Hospital, Riyadh, Saudi Arabia over a 20-year period from 1984 through 2004. The medical records of these patients were analyzed for their demographic characteristics, clinical features, operations performed and pathological diversity. Thirty-two patients comprised this study group. There is a male preponderance over females with a ratio of 2.2:1 (22 men and 10 women) and mean age of 51.8 (range 28-81 years). A painless lump was the most frequent clinical manifestation observed in 23(71.8%) patients followed by facial nerve dysfunction in 14 (43.7%) patients. Parotidectomy was performed in 22 (68.7%) patients: 16 superficial and 6 totals. A partial facial nerve sacrifice was undertaken in 14 (43.7%) and total nerve sacrifice was undertaken in 14 (43.7%) and total nerve sacrifice in 9 (28.1%) patients. Four (12.5%) patients presented with cervical lymph node metastases necessitating radical neck dissection. Nine (28.1%) patients had mucoepidermoid carcinoma, 8(25%) adenoid cystic carcinoma, 6 (18.7%) adenocarcinoma, not otherwise specified and 2 (6.2%) were reported to have carcinoma in plemorphic adenoma. Twenty (62.5%) specimens revealed high grade aggressive lesions and out of these 19 (59.3%) patients presented with stage III/IV disease. Malignant parotid tumors are exceedingly rare, occurring at earlier group with male preponderance and invariably declare at a late clinical stage in our community. Histopathological features hallmark a locally advanced disease with an aggressive behavior. (author)

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)

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To assess the nutritional status and prevalence of obesity among children with Down syndrome (DS. Methods: The study group comprised pre-pubertal children, with clinically and cytogenetically proven DS. Healthy siblings, closest in age to the DS children, were used as a control group. Body weight, height, body mass index (BMI, triceps skinfold thickness (TSFT, and macro- and micronutrient intakes were measured in both groups. The study was conducted in Riyadh, Kingdom of Saudi Arabia, between February and May 2011. Results: Children with DS were shorter than their siblings, but had comparable weights. The DS children had higher BMIs and higher TSFTs, compared with their siblings. The prevalence of overweight and obesity differed significantly between the DS and control groups. The DS children had significantly lower intakes of fat, protein, retinol, riboflavin, and potassium compared with their siblings. Conclusion: Obesity appears to be a prominent feature among Saudi DS children.

Spatial Autocorrelation of Cancer Incidence in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

Measurement of radon levels in groundwater supplies of riyadh with liquid scintillation counter and the associated radiation dose  

International Nuclear Information System (INIS)

A national groundwater surveillance programme was started for investigation of natural radioactivity levels in the year 2007. This paper presents 222Rn 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 226Ra 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 222Rn activities of deep wells ranged from 0.34±0.05 to 3.52±0.30 Bql-1 (average: 1.01±0.10 Bql-1), whereas those of shallow wells ranged from 0.72±0.08 to 7.21±0.58 Bql-1 (average: 2.74±0.24 Bql-1). The 222Rn concentrations levels were found to be in compliance with the proposed national limits of 11.1 Bql-1 and depend on the water source. (authors)

From barriers to bridges: An investigation on Saudi student mobility (2006-2009)  

Science.gov (United States)

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.

Parental responses to consanguinity and genetic disease in Saudi Arabia.  

Science.gov (United States)

In-depth interviews of 36 Saudi families whose children suffered from neuro-metabolic disorders were conducted at a specialist hospital in Riyadh in order to examine parental understanding of disease and attitudes towards future births and consanguineous marriages. Parents had difficulty accepting a genetic explanation for diseases that did not affect all children at the time of birth; they also expressed religious or folk beliefs to account for illness. Coping behaviours included denial and resignation to the situation, divorce and remarriage. Some families adopted a cautious approach to cousin marriages and future births; this was significantly related to their education level, but not to previous infant deaths. Awareness of medical facts brought little emotional comfort to parents but allowed for preventive measures through screening adult carriers and identifying affected infants. This study presents new material from Saudi Arabia to strengthen current awareness that the range of religious beliefs, social attitudes and reproductive behaviours adopted by families in a society undergoing rapid change is of direct relevance to health care.

Status of medical liability claims in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Background: With the evolution of healthcare services in Saudi Arabia, there has been an 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. Methods: A retrospective analysis of the official records of Medico- Legal malpractice claims over the period 1420H-1424H (1999-2003 was performed. The incidence among different medical specialties, location, and final resolution of each claim were identified. Results: 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 (2001-2002. 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 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. Conclusion: Adherence to standards of medical practice is by far the best approach to avoid or reduce the incidence of litigation.

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)

Selected Dietary Nutrients and the Prevalence of Metabolic Syndrome in Adult Males and Females in Saudi Arabia: A Pilot Study  

Directory of Open Access Journals (Sweden)

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.

The incidence rate of female breast cancer in Saudi Arabia: an observational descriptive epidemiological analysis of data from Saudi Cancer Registry 2001-2008  

Science.gov (United States)

Background This study presents descriptive epidemiological data related to breast 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-standardized incidence rate (ASIR), adjusted by the region and year of diagnosis. 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 20.0. 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.

Lifestyle factors associated with overweight and obesity among Saudi adolescents  

Directory of Open Access Journals (Sweden)

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.

Samples were collected from southern, central and eastern regions of Saudi Arabia using Malaise traps and sweep nets. Nine species of Tabanidae were identified, two for the first time from Saudi Arabia, Hybomitra peculiaris (Szilády) and Atylotus pulchellus (Loew). Therefore, the total number of Tabanidae in Saudi Arabia is 31 species. Remarks of the species recorded in this study were given. A key to the genera of Tabanidae occurring in the Arabian Peninsula is also provided. Available literature for Saudi Arabian Tabanidae is summarized and provided. It is concluded that the tabanid fauna of Saudi Arabia is more similar to that of the Palaearctic region than to the Afrotropical region. PMID:23961046

The Relationship Between Fast Food Consumption and BMI among University Female Students  

Directory of Open Access Journals (Sweden)

Full Text Available Fast food has become an important part of our diet and the increase in fast-food consumption is likely to continue. Our aim was to study the relationship between fast food and Body Mass Index (BMI and the pattern of consumption of fast food in female university students. Total of 141 female students from different study levels of Nutrition and Food Science Department, King Saud University (KSU, Riyadh Saudi Arabia were included. A survey questionnaire which contains three sections was used; firstly sociodemographic data, secondly fast food consumptions pattern and thirdly whether students apply basic nutrition knowledge in their selection of food or not. Height, weight and BMI were measured. We found that overweight and obesity were present in 25% of female students. Fast food consumption frequency of 1-2 times per week was high among them (74.5%. There is no significant relationship between fast food consumption, BMI and the pattern of consumption of fast food. There is a significant (p0.05 positive relationship between increase in size of fish sandwich meal and increase of BMI. However there is no significant relationship between portion size of other food types and BMI. Moreover, we found significant (p0.05 positive relationship between university study level and the knowledge in explaining why fast food is unhealthy.

Disability in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Disability is a complex, influential, dynamic, multidimensional challenge, and it can substantially limit major life activities of human beings and their ability to integrate/reintegrate into society. According to the World Health Organization reports almost 15% of the world’s population lives with certain types of disability, of whom 2-4% experience substantial difficulties in functioning. In Saudi Arabia, very limited research has been conducted on the prevalence and incidence of disability, and most of this is on disabled children. There are several difficulties associated with conducting research on disability related issues in Saudi Arabia. Here, we review the current situation of disability, disability research, and rehabilitation in Saudi Arabia from the published literature.

Attitude of Students Towards Cheating and Plagiarism: University Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available During their studies, many students commit some form of academic dishonesty, such as cheating and plagiarism, often to obtain higher grades than they are capable of. The current widespread use of the Internet, mobile and wireless devices has made it easier for students to illegally access information and at the same time it has become difficult for academic institutions to control and discover such instances. Hence, it is essential that students become aware of the seriousness of these offences and be encouraged to avoid them. In this study, the attitude towards cheating and plagiarism among female students in the College of Computer and Information Sciences (CCIS at King Saud University, Riyadh, Saudi Arabia was studied. We aim to highlight the most prevailing practices, the underlying reasons, the popular sources of illegal information and the conception of students towards the ethicalness of exercising such practices. The results of the study indicate that both cheating and plagiarism are common among our students, despite the fact that most of them believe that they are unethical and against religious values. After having analyzed the results, we tried to propose some recommendations that may help combat cheating and plagiarism among students in higher education.

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)

Prevalence and characteristics of cigarette smoking among 16 to 18 years old boys and girls in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To study the prevalence and characteristics of cigarette smoking among secondary school students (16- to 18-year-old boys and girls in Riyadh city, Saudi Arabia. Methods: We applied a standard two-stage, cross-sectional study design. Secondary schools for both boys and girls in Riyadh city were randomly selected using a cluster sampling method. We used the global youth tobacco survey (GYTS tool to achieve our objectives. Results: Among 1272 students (606 boys and 666 girls, the prevalence of those ever smoked cigarettes was 42.8% (55.6% of boys and 31.4% of girls. The prevalence of current smoking was 19.5% (31.2% of boys and 8.9% of girls. Despite the fact that the majority of students think smoking is harmful, most do not wish to stop smoking, and they had not tried to stop in the past year. Cigarette smoking is significantly associated with the male gender, having friends who smoke, and having parents who smoke, but is not significantly associated with the type of school attended. Conclusion: Smoking prevalence among secondary schools students in Saudi Arabia is high and alarming. There is a need to implement an education program about the risks of smoking and to include parents and friends as healthy models to prevent students from beginning to smoke.

Saudi National Assessment of Educational Progress (SNAEP  

Directory of Open Access Journals (Sweden)

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

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.

Prevalence of orofacial clefts in Saudi Arabia and neighboring countries: A systematic review  

Science.gov (United States)

Cleft lip and/or palate are among the most common birth defects in the world. The prevalence of these conditions varies considerably across geographic areas and ethnic groups. Objective The aim of this study was to carry out a systematic review and appraisal of the literature on the prevalence of cleft lip and/or palate in Saudi Arabia and comparable Middle Eastern countries. Materials and methods All published articles on orofacial clefts (OFC) in Saudi Arabia and its bordering countries in the Middle East with similar and comparable population characteristics were reviewed in July 2010. Results After reviewing the articles, only eight matched the inclusion criteria. Three studies were carried out in two regions in Saudi Arabia (Riyadh and Al-Qaseem). The other five studies were set in Dubai, Oman, and Jordan. The prevalence of cleft lip and/or palate reported in these studies varied greatly from 0.3 to 2.4 per 1000 live births. The birth prevalence of orofacial clefts in males was reported to be higher than in females. The isolated cleft palate prevalence was reported to be higher in females in most of the studies. Conclusion The eightfold variation in the prevalence of orofacial clefts between highest and lowest prevalence is likely to be due, at least in part, to problems with ascertainment, but there may also be underlying genetic or environmental factors that require further investigation.

Iraqi Invasion of Kuwait as Turning Point in Iran-Saudi Relationship  

Directory of Open Access Journals (Sweden)

Full Text Available Invasion of Kuwait by Iraqi army had significant impacts on regional and international spheres. The invasion affected relations of the regional countries in particular Iran-Saudi relationship as the most influential countries in the Persian Gulf region. The present article, first, takes into consideration Iran and Saudi Arabia relations in first decade after the Islamic revolution of Iran which finally gave rise to cutting off diplomatic relations in 1988 due to some severe tensions between the two sides. Then, the article examines Iraq’s invasion of Kuwait and occupying of Kuwait city, the capital, in August 1990 which led to some significant regional developments. The study also analyzes Iran’s neutrality stance in this case as well as in Second Gulf War which was reaction of international community pertaining to the occupation. Finally, the article concludes that how Iranian rational and pragmatic decision during the crisis resulted in changing of viewpoints of regional countries in particular Saudi Arabia which eventually led to renewing of diplomatic ties of Tehran-Riyadh in March 1991 after three years frigidity.

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)

Tertiary care availability and adolescent pregnancy characteristics in Saudi Arabia  

Science.gov (United States)

Background In this study, we aimed to assess the rate of adolescent delivery in a Saudi tertiary health care center and to investigate the association between maternal age and fetal, neonatal, and maternal complications where a professional tertiary medical care service is provided. Methods A cross-sectional study was performed between 2005 and 2010 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. All primigravid Saudi women ?24 weeks gestation, carrying a singleton pregnancy, aged <35 years, and with no chronic medical problems were eligible. Women were divided into three groups based on their age, ie, group 1 (G1) <16 years, group 2 (G2) ?16 up to 19 years, and group 3 (G3) ?19 up to 35 years. Data were collected from maternal and neonatal medical records. We calculated the association between the different age groups and maternal characteristics, as well as events and complications during the antenatal period, labor, and delivery. Results The rates of adolescent delivery were 20.0 and 16.3 per 1,000 births in 2009 and 2010, respectively. Compared with G1 and G2 women, G3 women tended to have a higher body mass index, a longer first and second stage of labor, more blood loss at delivery, and a longer hospital stay. Compared with G1 and G2 women, respectively, G3 women had a 42% and a 67% increased risk of cesarean section, and had a 52% increased risk of instrumental delivery. G3 women were more likely to develop gestational diabetes or anemia, G2 women had a three-fold increased risk of premature delivery (odds ratio 2.81), and G3 neonates had a 50% increased overall risk of neonatal complications (odds ratio 0.51). Conclusion The adolescent birth rate appears to be low in central Saudi Arabia compared with other parts of the world. Excluding preterm delivery, adolescent delivery cared for in a tertiary health care center is not associated with a significantly increased medical risk to the mother, fetus, or neonate. The psychosocial effect of adolescent pregnancy and delivery needs to be assessed.

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 "1"8O because of past groundwater formation by local rainfall from the western drift. Sahel zone groundwaters seem to show meridional variation of deuterium and "1"8O 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 "1"8O profiles. (author)

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

A review of clinically suspected sepsis and meningitis in infants under 90 days old in a tertiary care center in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: Infections in infants<90 days old are the leading cause of morbidity and hospitalization in neonatal practice. The etiological agents of sepsis (with or without meningitis in Saudi neonates <90 days old are vastly under-characterized. The aim of this study was to determine the bacterial etiology of neonatal sepsis and meningitis in these infants.Materials and methods: This retrospective study was conducted in King Khalid University Hospital, Riyadh, in the period from January 2007 to January 2011. All infants<90 days old with suspected sepsis during this period were examined for evidence of infection. Cultures, including blood and Cerebrospinal fluid (CSF were performed for all neonates.Results: A total of 304 cases of sepsis in infants <90 days were investigated. Community-acquired neonatal sepsis composed 284 of the studied cases present after the age of one month, while 20 infants were identified as having neonatal sepsis in the first month of life. Only 12 blood cultures were positive (four isolates of Staphylococcus epidermidis, two Staphylococcus aureus, two Staphylococcus hominis, one Enterobacter cloacae, one group B streptococcus, one diphtheroids and one with Bacillus species. Only three cases yielded positive CSF cultures. The first of these was positive for Aeromonas hydrophila, the second for Clostridium tertium and the third for Escherichia coli.Conclusion: Suspected sepsis in infants <90 days old is relatively common in this hospital, with 304 cases in a four-year period. However, positive bacterial cultures were rare, constituting only 5% of the suspected cases. J Microbiol Infect Dis 2011; 1 (2 : 47-52

Development of Regional Planning Criteria for Health Services in the City of Riyadh  

Directory of Open Access Journals (Sweden)

Full Text Available This study aimed at developing criteria for planning health services in the city of Riyadh through assessing the actual distribution of these services and comparing them with planning criteria adopted by the Municipality of Riyadh, local, Arab and foreign cities, in order to propose planning criteria that best serve citizens of Riyadh city more fairly and efficiently. Data related to health services and their attributes were gathered and incorporated into a GIS database. The results of the study showed regarding the primary health centers that the criterion of the service’s coverage rate of the Riyadh Municipality was slightly applied, notwithstanding the criterion of the served population was moderately applied, the criterion of the square meters of land per capita was slightly applied, the criterion of the served population was asymptotic to that one in Dubai. The criterion of the land's area allocated to per capita was relatively high in comparison with other cities. While the results regarding hospitals showed that the criterion of the service's coverage rate for the municipality was moderately applied, the criterion of the served population was asymptotic to that one in Dubai and the criterion of the land’s area allocated to per capita was relatively high in comparison with other cities.

Simulation and modeling of solar radiation in Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

A mathematical model is used to generate the hourly data for the total solar radiation on a horizontal surface. The generated data are based on the hourly recorded visibility data for 20 years (1970-1989). The model year technique was then applied to model the 20 years of hourly data of solar radiation into one statistically representative year. A model year of hourly data was then generated for the beam and diffuse components of solar radiation on a horizontal surface. Similarly, a model year of hourly data was also generated for the total solar radiation on tilted surfaces with different orientations with its beam, diffuse and reflected components. A simple methodology is proposed for calculating the solar radiation on vertical surfaces, based on a solar impact factor (SIF). Monthly means and daily totals of hourly sums for each month of the year are discussed. The hourly data of solar radiation for a typical day for each month of the year are presented. The data were generated for the four climatic zones of Saudi Arabia, the hot-dry (Riyadh), the warm-humid (Jeddah), the maritime inland desert climate (Dhahran) and the upland climate zone (Taif). The accuracy of the results is discussed and found to be above 90% representative. (author)

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

Science.gov (United States)

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.

Diabetes and Renal Transplantation: Saudi Experience  

Directory of Open Access Journals (Sweden)

Full Text Available We conducted this study to evaluate the prevalence and risk factors of diabetes mellitus (DM in our renal transplant population. We retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia, transplanted between 1979 and November 1998. The recipients were grouped according to the diagnosis of diabetes; group I: diabetes developed before transplantation (BTDM, group II: diabetes developed only after transplantation (ATDM and group III: did not have diabetes (NDM. There were 1112 patients? records included in the study. The mean age was 38.2 years and the mean duration of transplantation was 66.9 months. There were 113(10.2% patients in BTDM group, 134 (12.1% patients in the ATDM group and 865 (77.8% patients in the NDM group. There was no significant difference in the prevalence of hypertension among the study groups. In comparison to the other groups, the BTDM group had significantly more males (78.8%, more patients who were transplanted after 1990 (pre-cyclosporin era, more patients with grafts from living non-related donors (46%, higher incidence of acute rejection episodes (39%, higher mean serum creatinine and more patients treated with azathioprine (71%. The ATDM group had significantly higher mean age (46.4 years, higher mean duration of transplantation (91.5 months, higher rate of retransplantation (8.2%, higher mean serum cholesterol level (6.0mmol/L and more frequently abnormal electrocardiogram (24.6% than the other two groups. The ATDM group had comparable mean weight (70.2 kg to the BTDM group but significantly higher than the NDM group (66.1kg. The NDM group had significantly higher mean dose of cyclosporine (3.3 mg/kg/day and higher mean dose of prednisone (0.16 mg/kg/day than the other groups. The only independent risk factor for developing DM after transplantation was advancing age. The currently used low-dose steroid therapy was not significantly associated with development of DM after renal transplantation. Nevertheless DM is an important co-morbid condition in the transplant population and is associated with increased risk for cardiovascular and cerebrovascular events.

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)

Energy analysis of Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

This study provides an energy outlook for Saudi Arabia's energy resources, their production and consumption, as well as their future projections. Crude oil, natural gas and refined products, and electricity are the main energy resources of the country. Saudi Arabia is the only country in the world that has the largest crude oil reserves and this is one of the main energy producers. The high growth rates of Saudi Arabia's population and the sectorial energy utilisation are the two main factors affecting its energy consumption dramatically. Moreover, Saudi Arabia is not only one of the main energy producers in the world but is also one of the world's largest energy consumers per capita. (Author)

Seroprevalence of some bovine viral respiratory diseases among non vaccinated cattle in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

Assessment of Educational Environment of Surgical Theatre at a Teaching Hospital of a Saudi University: Using Surgical Theatre Educational Environment Measures  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: This study was aimed to determine how medical interns perceive the important factors of the learning environment the surgical theatre at the teaching hospital of the medical school, University of Dammam (UoD. The study also investigated the relationships between the learning environment and academic achievements. Finally, it determined the role and significance of gender on the above perceptions and relationships.Methods: The Surgical Theatre Educational Environment Measure (STEEM was used to identify the perceptions of interns on the most important factors prevalent in the surgical theatre as an educational environment. STEEM was administered to all interns during the period of June-September 2009. Ninety-one out of 145 students completed the questionnaire representing a response rate of 63%. Non-parametric statistical analysis was performed using Statistical Package for the Social Sciences (SPSS Version 17.Results: The STEEM was shown to be internally consistent for the assessment of the overall educational environment in the surgical theatre of UoD. The overall STEEM mean score was 110. For male and female students, the mean scores were 114 and 107 respectively. There were statistically significant gender differences in the perceptions of "learning opportunities" and "teaching and training". Females rated these subscales lower than males. There were no significant associations between academic achievements and perceptions of the educational environment.Conclusion: The interns perceived the learning environment of the surgical theatre as less than satisfactory. In comparison with the males; the perception of the females was less positive, particularly in the areas of learning opportunities, and teaching and training. The study also revealed some other problematic areas in the learning environment of surgical theatre of the teaching hospital of UoD. The results imply that there is much room for improvement. They also indicate that equal opportunities for learning and training should be given to both sexes.

A First Look on iMiner's Knowledge base and Detecting Hidden Hierarchy of Riyadh Bombing Terrorist Network  

DEFF Research Database (Denmark)

  - 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.

Genome at juncture of early human migration: a systematic analysis of two whole genomes and thirteen exomes from kuwaiti population subgroup of inferred saudi arabian tribe ancestry.  

Science.gov (United States)

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

Radon in Saudi houses  

International Nuclear Information System (INIS)

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

Bone mineral density among postmenopausal Saudi women  

International Nuclear Information System (INIS)

Osteoporosis is reported to be common among postmenopausal Saudi women. The reported incidence varies between 50-60%. Different machines were used to reach these conclusions. At present it is believed that dual energy x-ray absorptiometry (DEXA) is the most accurate method to diagnose osteoporosis. This study was conducted to measure bone mineral density (BMD) measurement of lumbar spine and the upper femur of Saudi postmenopausal women attending orthopedic clinic with unrelated complaints. This study comprises of 256 patients attending orthopedic clinics at King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia between January 2002 and June 2003. The data gathered was age, duration of menopause, height and weight for body mass index (BMI) calculation. Women with secondary osteoporosis were excluded from study. Patient's orthopedic complaints were also recorded in the database. Bone mineral density measurements were carried out using Hologic total body DEXA machine. The data were analyzed using SPSS package. The data of 256 patients was available for analysis. The average age of patients screened was 57.62 years (49-76) SD+-6.71. The BMI was 21.3-42.9 Kg/m (SD+-5.34). The BMD of lumbar spine was 0.785 gm/cm2 (0.527-1.023) SD +-0.142 and that of the hip region was 0.764 gm/cm2 (0.500-1.069) SD +-0.149. As per the WHO classification 59 women (23%) were classified as normal with the T score of -0.82, 78 (30.5%) as osteopenic with T score -2.5 and 119 (46.7%) as osteoporosis with T score -3.58. When the BMD of the hip was analyzed 62 (24.2%) were normal T score -1.0, 81 (31.6%) as osteopenic, T score -2.5 and 113 (44.1%0 as osteoporotic, with a T score of -3.1. on the basis of analysis of lumbar spine 190 (74.2%) had increased risk of fracture as compared to the analysis of hip 59% were at increased risk of fracture. Our results indicate that postmenopausal Saudi women suffer from osteoporosis and osteopenia higher than those from other parts of the country. Necessary steps are needed so as to avoid osteoporosis and its complications which could end up in epidemic proportions. (author)

Pattern of glomerular disease in the Saudi population: a single-center, five-year retrospective study.  

Science.gov (United States)

Glomerular diseases continue to be the leading cause of end-stage renal disease (ESRD) globally. Hence, it is important to recognize the pattern of glomerular diseases in different geographical areas in order to understand the patho-biology, incidence and progression of the disorder. Published studies from different centers in Saudi Arabia have reported contradicting results. In this retrospective study, we report our experience at the Armed Forces Hospital, Riyadh, Saudi Arabia. A total of 348 native renal biopsies performed at our center on patients with proteinuria >1 g, hematuria and/or renal impairment during a period of 5 years (between January 2005 and December 2009) were studied by a histopathologist using light microscopy, immunofluorescence and electron microscopy, and were categorized. Results showed that primary glomerular disease accounted for 55.1% of all renal biopsies. The most common histological lesion was focal and segmental glomerulosclerosis (FSGS) (27.6%), followed by minimal change disease (MCD) (17.7%) and membrano-proliferative glomerulonephritis (MPGN) (13.0%). Secondary glomerular disease accounted for 37.9% of the glomerular diseases, with lupus nephritis (LN) being the most common lesion (54.5%), followed by hypertensive nephrosclerosis (22%), post-infectious glomerulonephritis (7.5%), diabetic nephropathy (DN) (6.8%) and vasculitides (4.5%). Four percent of all biopsies turned out to be ESRD while biopsy was inadequate in 2.8% of the cases. In conclusion, our study showed that FSGS was the most common primary GN encountered, while LN was the most common secondary GN. We encountered 14 cases of crescentic glomerulonephritis. Also, the prevalence of MPGN, MCD, IgA nephropathy and membranous GN was many folds higher in males when compared with the Western data. We believe that it is mandatory to maintain a Saudi Arabian Renal Biopsy Registry to understand better the pattern of glomerular disease in the Saudi population and to follow any change in trend.

Occurrence of fluoride in ground waters of Saudi Arabia  

Science.gov (United States)

The presence of elevated levels of fluoride in groundwater is considered a global problem. Fluoride in water derives mainly from dissolution of natural minerals in the rocks and soils with which water interacts. The most common fluorine-bearing minerals are fluorite, apatite and micas. Anthropogenic sources of fluoride include agricultural fertilizers and combustion of coal. In the present research, a survey of wells ( n = 1,060) was undertaken in all the 13 regions of the Kingdom of Saudi Arabia to assess the contained fluoride (F) levels. The results indicated variation in fluoride levels from 0.10 to 5.4 mg/L as F throughout the kingdom. The average fluoride levels in milligrams per liter as F were as follows in descending order: 1.80 (Hadwood Shamalyah), 1.37 (Hail), 1.33 (Eastern Province), 1.16 (Al Jouf), 1.11 (Qassim), 1.01 (Riyadh), 0.90 (Madina Al Munnawara), 0.81 (Tabouk), 0.74 (Makkah Al- Mukaramma), 0.73 (Jizan), 0.66 (Asir), 0.64 (Najran), and 0.60 (Al Baha). The results indicated that fluoride levels exceeded the USEPA maximum contaminant limits for drinking water (4 mg/L) in several wells ( n = 7) in different regions of the kingdom and that 13.96 % of the wells exceeded the World Health Organization recommended levels (1.5 mg/L). The results were also compared with the secondary USEPA contaminant standards of 2.0 mg/L for fluorides.

Nuptiality pattern in Saudi Arabia.  

Science.gov (United States)

The data of this work are based on the 'Saudi Maternal and Child Health Survey' conducted in 1991. This was a nationwide house to house field survey. The study included 6294 ever-married Saudi female in the childbearing age who represent the target population. They were randomly selected from both urban and rural settings of the five geographical areas of Saudi Arabia. The mean current age of the sample of ever-married women was 31 years and the mean age at first marriage was 17 and 16 years for urban and rural females, respectively. Education was associated with upward shift of the age at first marriage. About 20 per cent of the sampled ever-married Saudi females got married before their 15th birthday and 83 per cent before reaching 20 years of age. These percentages are even higher in rural than urban settings. The overall percentage of women who were currently married at the time of the survey was 96 per cent. The divorced and widowed women of childbearing age were 2 and 3 per cent, respectively, of the total. Husband's educational level had positive impact on the frequency of divorce. The latter was highest among women married to illiterate husbands with a dose response pattern. Comparison has been made with the situation 4 years ago. An increase in literacy rates among Saudi ever-married women and their husbands was observed, however, a significant (P < 0.05) difference still exists between female and male literacy rates (38 and 71 per cent, respectively). The events of early marriage, before the age of 15 years, became less frequent. There is an overall decline in teenage marriages which explains a large part of the recent changes observed in nuptiality and pattern of birth in Saudi Arabia. PMID:8568953

Risk Factors for Obesity among Saudi Female College Students  

Directory of Open Access Journals (Sweden)

Full Text Available Obesity is alarmingly raising in young people necessitating foridentification of precise causes specific for populations. The aim of the present study is to determine independent contribution of parental socioeconomic variables and self-life style factors to obesity in Saudi female college students. We performed a cross-sectional study using a random selection of 300 women aged 18–26 years recruited from the female campus of University of Hail, Saudi Arabia and collected self-reported information to meet study objectives. Around 32 % of females were either overweight or obese and the study subjects with a family history of maternal obesity and habit of limited snacking had higher odds for obesity. No associations were found between obesity and parental income and education status; and skipping breakfast and physical activity behaviours of the subjects. Maternal obesity could be a considerable risk factor for obesity in female subjects.

Saudi Arabia is committed to free trade in petrochemicals  

Energy Technology Data Exchange (ETDEWEB)

Saudi Arabia sees protectionism in the petrochemical industry as self-defeating and against the interests of the world economy. Taking a world view based on the forces of a free market, the Minister of Petroleum and Mineral Resources argues that a free market, at best, is burdened with second-best solutions unless it is a universal free market. The burden is greatest on developing countries. Saudi Arabia's industrialization program is aimed at developing independence from oil exports by enhancing the value-added of hydrocarbon and mineral resources through manufacturing activities. An internal free market based on competition and privatization is forming a stronger economic base than government nurturing of infant industries.

Carcinoid tumors of the appendix: our experience in a university hospital  

International Nuclear Information System (INIS)

To present our experience of carcinoid tumors of the appendix managed at a university teaching hospital. Complex symptomatology, varied biochemical affections and different surgical therapeutic modalities are discussed. The medical records of all the patients who underwent consecutive appendectomies at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from 1994 to 1999 were retrospectively analyzed. The data of patients identified to have histological evidence of carcinoid tumors of the appendix were further reviewed for the demographic details, indications for surgery, surgical procedure, tumor localization in the appendix and size; concomitant appendicitis and further surgical procedures were considered. During the study period 1547 appendectomies were performed and out of these, 9 (0.6%) cases were reported to have carcinoid tumors of appendix. There were 4 male and 5 female patients, age range 17-51 years (29.8 years). Seven subjects had a clinical evidence of appendicitis while 2 presented with chronic abdominal pain. there were 6 open and 3 laparoscopic appendectomies. Six carcinoid tumors were encountered at the appendiceal apex, two at the midportion and one at the base with a mean diameter of 9.5 mm (rang 4-19 mm). One patient had histologically confirmed residual tumor, which necessitated a right hemicolectomy 3 weeks later. All patients remained disease free during a mean follow-up of 7 years (range, 4-10 years). Carcinoid tumors of the appendix are extremely rare and invariably remain asymptomatic. Simple appendectomy offers adequate relief while the need for further extensive surgery depends on tumor characteristic and dissemination. Despite an excellent prognosis, all reported patients should be followed up with urinary 5-hydroxyindoleacetic acid and abdominal ultrasonography. (author)

THE ATTITUDE AND THE IMPACT OF THE AMERICAN ENGLISH AS A GLOBAL LANGUAGE WITHIN THE SAUDI EDUCATION SYSTEM  

Directory of Open Access Journals (Sweden)

Full Text Available This paper investigates the impact of 9/11 on the educational system in Saudi Arabia. In particular, it discusses how this phenomenon took its course to influence the English teaching system in Saudi Arabia, and the attitude and the impact of this new phenomenon in the Saudi society, in light of the current debate between Arab linguists on the issue of more English less Islam. It also presents a case study on a group of Saudi freshmen students studying English at King Abdul Aziz University, Jeddah, Saudi Arabia. A 12-item questionnaire, related to this topic was distributed to 65 Saudi students studying English in their second semester of the New English Curricula. The findings provide valuable data on how the youth feel towards Western ideology, learning English and Western culture. Although the findings are context specific, they indicate that the Saudi students agree (for the most part that both the study of the English language and its culture are necessary in order to develop their English comprehension.

Rock Art of Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available It is not only oil in which Saudi Arabia is rich, but it is also among the four richest rock art regions of the world. Hundreds and thousands of petroglyphs, painted rock art, and ancient Arabian inscriptions sites are located all over the country, representing various cultural phases, from the Neolithic until the recent past. One can see the naturalistic, schematic, abstract, mythical, and mystical images representing ancient ideology, thoughts about the metaphysical world, religious entity, economy, environment, human activities, and variety of animal types, according to particular climatic and environmental conditions. The rock art of Saudi Arabia is the mirror of its rich cultural heritage of so-called Bedouin or desert dwellers that surprises the world with its 4000 archaeological and more than 1500 rock art sites.

Rotavirus infection in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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.

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)

Drug-resistant ventilator associated pneumonia in a tertiary care hospital in Saudi Arabia  

Science.gov (United States)

BACKGROUND: There is a wide geographic and temporal variability of bacterial resistance among microbial causes of ventilator-associated pneumonia (VAP). The contribution of multi-drug resistant (MDR) pathogens to the VAP etiology in Saudi Arabia was never studied. We sought to examine the extent of multiple-drug resistance among common microbial causes of VAP. MATERIALS AND METHODS: We conducted a retrospective susceptibility study in the adult intensive care unit (ICU) of King Abdulaziz Medical City, Riyadh, Saudi Arabia. Susceptibility results of isolates from patients diagnosed with VAP between October 2004 and June 2009 were examined. The US National Healthcare Safety Network definition of MDR was adopted. RESULTS: A total of 248 isolates including 9 different pathogens were included. Acinetobacter spp. was highly (60-89%) resistant to all tested antimicrobials, including carbapenems (three- and four-class MDR prevalence were 86% and 69%, respectively). Pseudomonas aeruginosa was moderately (13-31%) resistant to all tested antimicrobials, including antipseudomonal penicillins (three- and four-class MDR prevalence were 13% and 10%, respectively). With an exception of ampicillin (fully resistant), Klebsiella spp. had low (0-13%) resistance to other tested antimicrobials with no detected MDR. Staphylococcus aureus was fully susceptible to vancomycin with 42% resistance to oxacillin. There were significant increasing trends of MDR Acinetobacter spp. however not P. aeruginosa during the study. Resistant pathogens were associated with worse profile of ICU patients but not patients’ outcomes. CONCLUSION: Acinetobacter in the current study was an increasingly resistant VAP-associated pathogen more than seen in many parts of the world. The current finding may impact local choice of initial empiric antibiotics.

The Saudi Initiative for asthma  

Directory of Open Access Journals (Sweden)

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.

Climatic conditions for Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

The degree-day concept has been in use for more than 60 years as a means for utilities and fuel suppliers to predict the energy demand of the average population of buildings in any given location. It has also been used to assist the building design profession in estimating monthly and annual cooling and heating requirements of specific buildings in different locations. This paper presents the climatic conditions for Saudi Arabia, including the monthly average ambient temperature, the values of cooling and heating degree-days for different base temperatures, and the winter and summer outdoor design conditions for 20 cities in Saudi Arabia. These cities are located in five different climatic zones. The data presented in this paper will be useful to the building design profession and to designers and manufacturers of heating, ventilating, air-conditioning, and refrigerating (HVAC and R) equipment. It will also cover part of the present lack of information in ASHRAE Handbooks concerning degree-days and outdoor design conditions in Saudi Arabia.

Cracking problem in unplasticized polyvinyl chloride fittings used in Riyadh domestic sewer connections  

Energy Technology Data Exchange (ETDEWEB)

The domestic connections to the sanitary sewer system in Riyadh consist of unplasticized polyvinyl chloride pipe and fittings which are joined together with a rubber ring to seal the joints. The majority of the domestic connections are deep and consequently they were installed using vertical risers to avoid excessive excavations. During the inspection and testing procedure for handing over the completed portions of the sewage system, it was discovered that a large proportion of the domestic connections were failing the required water test. Re-excavation revealed that the widespread failure was due to the cracking of the fittings used in the domestic connections.

How do medical students in their clinical years perceive basic sciences courses at King Saud University?  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives : The inclusion of detailed basic science courses in medical school curricula has been a concern of students. The main objective of this study was to explore the attitudes of medical students towards basic sciences courses taught to them in the preclinical years and the applicability of these courses to current clinical practice. Design and Setting : A cross-sectional survey was conducted during 2008-2009 among medical students in their clinical years at King Saud University, Riyadh, Saudi Arabia. Methods : Thirty percent of all students (n=314 were randomly selected to receive a questionnaire designed to evaluate their opinions about course load, ability to recall information, value of practical sessions, availability of references and course guidelines, and the applicability of individual courses to clinical practice. Results : Students identified anatomy and pathology as the courses most overloaded with content (76% and 70%, respectively. Half of the students felt they retained the most knowledge of physiology (50%, while less than a quarter of students (19% felt they retained the most information from biochemistry coursework. The role of practical sessions in facilitating theoretical understanding was more evident in anatomy (69%. Physiology was perceived as the subject with the highest applicability to clinical practice (66%, while pathology (29% was identified as the subject with the least practical application. Students became increasingly negative in their opinions about basic science courses as they progressed through their medical education. Conclusion : Current attitudes of medical students towards their basic science courses indicate a need to reform the curricula so as to maximize the benefit of these courses.

Simulating and Forecasting Flooding Events in the City of Jeddah, Saudi Arabia  

Science.gov (United States)

Metropolitan cities in the Kingdom of Saudi Arabia, as Jeddah and Riyadh, are more frequently experiencing flooding events caused by strong convective storms that produce intense precipitation over a short span of time. The flooding in the city of Jeddah in November 2009 was described by civil defense officials as the worst in 27 years. As of January 2010, 150 people were reported killed and more than 350 were missing. Another flooding event, less damaging but comparably spectacular, occurred one year later (Jan 2011) in Jeddah. Anticipating floods before they occur could minimize human and economic losses through the implementation of appropriate protection, provision and rescue plans. We have developed a coupled hydro-meteorological model for simulating and predicting flooding events in the city of Jeddah. We use the Weather Research Forecasting (WRF) model assimilating all available data in the Jeddah region for simulating the storm events in Jeddah. The resulting rain is then used on 10 minutes intervals to feed up an advanced numerical shallow water model that has been discretized on an unstructured grid using different numerical schemes based on the finite elements or finite volume techniques. The model was integrated on a high-resolution grid size varying between 0.5m within the streets of Jeddah and 500m outside the city. This contribution will present the flooding simulation system and the simulation results, focusing on the comparison of the different numerical schemes on the system performances in terms of accuracy and computational efficiency.

Wavelet based hurst exponent and fractal dimensional analysis of Saudi climatic dynamics  

International Nuclear Information System (INIS)

This paper utilizes wavelets technique to calculate the Hurst exponent, the fractal dimensions and finally the climate predictability indices of daily average time series of air temperature, surface pressure, precipitation, relative humidity and wind speed for nine meteorological stations (Dhahran, Gizan, Jeddah, Yanbu, Abha, Hail, Guryat, Turaif and Riyadh) spread over different parts of Saudi Arabia. The meteorological data (daily means of temperature, pressure, relative humidity and wind speed and daily totals for precipitation) used in this study covers a period of 16 years starting from 1990 to 2005. The Hurst exponents, calculated using wavelet method, were used to find the fractal dimensions for each of the meteorological parameters. Finally, the predictability indices of temperature, pressure, precipitation and wind speed were used to establish the climate predictability indices. The climate predictability indices of precipitation and wind speed time series were found to be independent of the temperature and pressure. The predictability indices of individual parameters were found to have persistence behavior for entire data set while anti-persistence, in most of the cases, for winter and summer data sets.

Examining Theory of Reasoned Action in Internet Banking Using SEM among Saudi Consumers  

Directory of Open Access Journals (Sweden)

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.

Medication burden of Saudi Arabian women receiving antiresorptive therapy  

Directory of Open Access Journals (Sweden)

Full Text Available Mir Sadat-Ali,1 Bader Al-Shafie,2 Abdallah S Al-Omran,1 Mohammed Q Azam11Department of Orthopedic Surgery, College of Medicine, University of Dammam, Dammam, Saudi Arabia; 2Department of Pharmacy, King Fahd Hospital of the University, Al Khobar, Saudi ArabiaBackground and purpose: Osteoporosis is common in the Saudi Arabian population, and its successful treatment requires full compliance. Patients who require antiresorptive therapy, such as oral bisphosphonates, may suffer from other diseases requiring medications, which increases the medication burden and ends up in drug noncompliance on the part of patients, making them vulnerable to osteoporosis-related fractures. We decided to undertake this study to analyze the concomitant medications that osteoporotic patients are receiving at King Fahd Hospital of the University, Al Khobar.Methods: Osteoporotic patients receiving antiresorptive therapy (ART at King Fahd Hospital of the University, Al Khobar, were identified through the database of the QuadraMed Patient Care system and cross-checked with the radiology database of the dual-energy X-ray absorptiometry scan and pharmacy drug-dispensing system between January 2009 and December 2009. Concomitant medication is defined as the use of other drugs for $30 days with oral bisphosphonates, calcium, and vitamin D. Medication burdens are defined as mild (?1 concomitant medication, moderate (?2 and ?4 medications, and severe (?5 medications. The demographic data, such as age, sex, and diagnosis, were collected from the medical records. The data were analyzed using the Statistical Package for the Social Sciences (SPSS.Results: During the study period, 516 patients were diagnosed with osteoporosis, and 473 were on ART while the rest were using anabolic Teriperatide. Sixty-eight (14.4% of the patients, with an average age of 50.15 ± 2.4 years, were on one medication besides ART, vitamin D, and elemental calcium; 129 (27.3% of the patients, with an average age of 51.6 ± 9.7 years, were taking 3.32 medications, and 276 (58.3% of the patients, with a mean age of 62.1 ± 10.7 years, were on 8.02 concomitant medications. The most common concomitant medications in use were cardiac, endocrine, systemic nonsteroidal anti-inflammatory drugs, and analgesics, in that order. This study suggests that the majority of Saudi women who are osteoporotic and undergoing oral bisphosphonate therapy have a concomitant medication burden of $5 other medications. For full compliance with the therapy, the patients' medication burden should be considered prior to selecting the treatment route.Keywords: osteoporosis, concomitant medications, polypharmacy, compliance

A passive solar test facility for Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

A passive solar test facility has been designed for Dammam, Saudi Arabia. It will be located on the campus of King Faisal University, adjacent to the Persian Gulf. This maritime desert climate is terribly sevre, and one for which it is a formidable challenge to design a year around thermally efficient building. This facility incorporates seven different passive strategies: proper orientation, operable shading for windows, flow-through ventilation, externally insulated thermal mass, wind tower with direct evaporative cooling, indirect evaporative cooling through a double shell, and solar water heating. Construction should begin in June of 1983. Upon completion, the building will be monitored for at least two years.

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).

Factors Influencing the Use of Learning Management System in Saudi Arabian Higher Education: A Theoretical Framework  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this paper is to present the theoretical framework underlying a research on factors that influence utilization of the Jusur Learning Management System (Jusur LMS in Saudi Arabian public universities. Development of the theoretical framework was done based on library research approach. Initially, the existing literature relevant to the subject was reviewed to determine the important variables related to factors influencing the use of LMS in higher education. The paper provides insights of the external and internal variables or factors that influence the use of Jusur LMS for teaching and learning purposes. The internal variables consist of the attitude of Saudi Arabian faculty members towards using LMS, their beliefs towards e-learning, and their competence level in using LMS. The external variables consist of barriers faced by the faculty members and demographic factors. This study was limited to the use of Jusur LMS, one of the e-learning management tools used in Saudi Arabian universities, and surveyed faculty members of Saudi Arabian public universities. This theoretical framework can be adapted to suit the requirements of other similar studies related to planning and implementation of various technology programs in higher education.

Differences in prostate cancer detection between Canadian and Saudi populations  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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

Saudi decree encourages MTBE, Chevron aromatics plant  

International Nuclear Information System (INIS)

Chevron Chemical (Houston), encouraged by a new Saudi royal decree that establishes extremely low feedstock prices, is in final negotiations to build a novel aromatics plant in Saudi Arabia. Chevron says it plans to close the deal and announce details the first week of March. The unit will be based on Chevron's Aromax reforming process, which uses a zeolite catalyst to convert light naphtha into benzene and toluene. No existing plant is using the technology, but Chevron is building a $250-million, 150-million gal/year Aromax unit at its refinery site in Pascagoula, MS, and Idemitsu has licensed the process for a plant in Chiba, Japan. The Saudi decree, issued late last year, pegs domestic feedstocks - propane, butane, and naphthas - at 30% below the lowest price of the prior quarter in major non-domestic markets. That clarifies and guarantees the Saudi feedstock price, which has always been nebulous, and thus allows project feasibility to be more clearly assessed. The decree is designed to encourage further private petrochemical investment in the country. In particular, the Saudi government hopes guaranteed low prices for butane will encourage more methyl tert-butyl ether (MTBE) projects. Arabian American Chemical, a 50/50 joint venture between Mobile and Arabian Chemical Investments, said in October of last year that its 830,000-m.t./year MTBE project at Yanbu, Saudi Arabia, would go ahead if feedstock questions could be resolved. The decree apparently resolves those questions

Saudi Arabia: energy, developmental planning, and industrialization  

Energy Technology Data Exchange (ETDEWEB)

Petrodollars, having catapulted Saudi Arabia to the forefront of the global economy, now fuel the Kingdon's industrial-development process. The rapid influx of oil-generated funds into this developing country carries its own set of chracteristics and demands. Government officials and Saudi and non-Saudi academicians and industry representatives offer varied views and responses to the economic and international complexities of development. Moving from a general overview to specific economic and political topics, the book emphasizes the importance of carefully developed government growth programs to the creation of a well-balanced and industrially diverse society. Contributors examine the roles of the petroleum sector and technology transfer, trace the interdependence of Saudi Arabia and the industrialized countries, and analyze the roots of indigenous and imported inflation. They also consider Saudi Arabia's new role in international finance and development assistance. A discussion of the special historical and cultural factors that affect the Saudi transition from tribal society to industrialized nation provides a background for understanding the particular human-resource needs and goals of the nation. The book concludes with an analysis of the Third Development Plan as a blueprint of the development objectives and government-spending priorities in manpower, industrialization, and the agricultural and petroleum sectors. 10 figures, 20 tables.

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

Measurements of radiation level in petroleum products and wastes in Riyadh City Refinery  

International Nuclear Information System (INIS)

Recent concern has been devoted to the hazard arising from naturally occurring radioactive materials (NORM) in oil and gas facilities. Twenty-seven petroleum samples were collected from Riyadh Refinery. Fourteen samples were products and 13 were waste samples; three of them were scale samples and 10 were sludge samples. The specific radioactivities of 238U, 232Th, 226Ra, 224Ra, 40K, and 235U for all samples were determined using high-resolution gamma-ray spectrometry. The radium equivalent activity, radiation hazard indices and absorbed dose rate in air for all waste samples were estimated. The radon emanation coefficient of the waste samples was estimated. It ranged between 0.574 and 0.154. The age of two scale samples was determined and found to be 2.39 and 3.66 years. The chemical structure of the waste samples was investigated using X-ray florescence analysis (XRF) and Mg, Al, Si, S, Cl, Ca and Fe were found in all samples. From this study, it was noticed that the concentrations of the natural radionuclides in the petroleum wastes were higher than that of the petroleum products

Travel epidemiology: the Saudi perspective.  

Science.gov (United States)

The Kingdom of Saudi Arabia occupies four-fifths of the Arabian Peninsula, with a land area of 2 million square kilometres. Saudi Arabia holds a unique position in the Islamic world, as the custodian of the two holiest places of Islam, in Mecca and Medina. Annually, some 2 million Muslims from over 140 countries embark on Hajj. This extraordinary en masse migration is a unique forum for the study of travel epidemiology since the Hajj carries various health risks, both communicable and non-communicable, often on a colossal scale. Non-communicable hazards of the Hajj include stampede and motor vehicle trauma, fire-related burn injuries and accidental hand injury during animal slaughter. Communicable hazards in the form of outbreaks of multiple infectious diseases have been reported repeatedly, during and following the Hajj. Meningococcal meningitis, gastroenteritis, hepatitis A, B and C, and various zoonotic diseases comprise some of the possible infectious hazards at the Hajj. Many of these infectious and non-infectious hazards can be avoided or averted by adopting appropriate prophylactic measures. Physicians and health personnel must be aware of these risks to appropriately educate, immunize and prepare these travellers facing the unique epidemiological challenges of Hajj in an effort to minimize untoward effects. Travel epidemiology related to the Hajj is a new and exciting area, which offers valuable insights to the travel specialist. The sheer scale of numbers affords a rare view of migration medicine in action. As data is continually gathered and both national and international policy making is tailored to vital insights gained through travel epidemiology, the Hajj will be continually safeguarded. Practitioners will gain from findings of travel related epidemiological changes in evolution at the Hajj: the impact of vaccinating policies, infection control policies and public health are afforded a real-world laboratory setting at each annual Hajj, allowing us to learn from this unique phenomenon of migration medicine.

Methods: Among 129 elderly residents, 83 (51 males, and 32 females of them were interviewed and clini-cally examined according to WHO criteria by two calibrated dentists. Results: The mean age of the subjects was 72 ± 8.5. Male subjects had a higher smoking rate than females. Among elderly subjects below 74 years old, 20.8% had a functional dentition (> or = 20, while only 6.7% for those aged greater or equal to 75 years (p = 0.0004. Mean number of the sound teeth in all subjects was 6.7 ± 8.5. The mean number of DMFT was 18.6 ± 12.6. The missing component was the highest (16 ± 13 for both genders. The mean number of decayed roots was 2.75 ± 3.95 in males and 0.63 ± 1.96 in females. Overall, males had more sound and decayed teeth and less filled and missed teeth than females. There was no significant difference between males and females in periodontal problems except the calculus scores. The majority of subjects in need for tooth extraction were male subjects. With no gender difference 63% were in need for restorations, 40% needed upper and lower full dentures. Need for partial dentures was 38% upper and 48% lower. Conclusion: The oral health of the institutionalized elderly population in Saudi Arabia is generally poor and their treatment needs are high.

METHODS: This is a hospital based cross-sectional study which was conducted on all Saudi patients who underwent coronary angiography without symptoms of peripheral arterial disease at King Fahd Hospital of the University, Al-Khobar Saudi Arabia. All patients underwent measurement of their ABPI. The study was carried out between December 2010 and November 2011. RESULTS: During the study period, two hundred and five patients were included. Fifty-nine (28.8% patients were Group II (ABPI ? 0.90 and the rest was Group I (ABPI > 0.90. Significant correlation was also found between low ABPI and the extent of CAD (mean number of arteries involved in Group I was 1.78 ± 0.83 compared to 2.10 ± 0.736 in Group II p = 0.011. Nevertheless, the correlation between low ABPI, and the severity of presentation of CAD were also significant (Incidence of myocardial infarction with congestive heart failure was 0.5% in Group I compared to 12% in Group II p CONCLUSION: The ABPI is an important prognostic indicator for Saudi patients with CAD.

A Topic Diathesis In Hereditary Ichthyosis Patients Attending A Tertiary Health Care Center In Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

Science.gov (United States)

Background and Objectives: Saudi Arabia has one of the highest prevalence of diabetes. This study was conducted with the following objectives: (1) To study the socio-demographic profile of diabetic patients in Abha. (2) To find the socio-demographic determinants of compliance among diabetic patients in Abha. Material and Methods: A self administered questionnaire which had detailed the socio-demographic features and various aspects of compliance was used on a random sample of registered diabetics at two primary health care centres of Abha. Results: Most of the patients (70.4 percent) were between 40-60 years age. Most of the patients were men (about 60 percent) and Saudis. Majority of patients did not have a university education. Young patients (age<40) were more compliant with all aspects of management, except medication (23.8 percent). Women were significantly more compliant with exercise (49.7 percent), while men were significantly more compliant with follow up (81.1 percent). Saudi patients were significantly compliant with medication (79.2 percent), while non Saudis were compliant with exercise (62.9 percent). All single patients were diet compliant. Smokers were significantly less compliant with exercise. Patients with normal BMI were significantly more compliant with diet and exercise. Conclusion: Patients were found to be generally less compliant towards the regimen. Socio-demographic factors which were significantly associated with non compliance were age, gender, nationality, educational status, marital status, smoking status and BMI. PMID:24551644

Epidemic outbreaks, diagnostics, and control measures of the H5N1 highly pathogenic avian influenza in the Kingdom of Saudi Arabia, 2007-08.  

Science.gov (United States)

The first outbreak of H5N1 highly pathogenic avian influenza (HPAI) in the Kingdom of Saudi Arabia (KSA) occurred in two "backyard" flocks of Houbara bustards and falcons in February 2007. Subsequent outbreaks were seen through the end of 2007 in "backyard" birds including native chickens, ostriches, turkeys, ducks, and peacocks. From November 2007 through January 2008, H5N1 HPAI outbreaks occurred in 19 commercial poultry premises, including two broiler breeder farms, one layer breeder farm, one ostrich farm, and 15 commercial layer farms, with approximately 4.75 million birds affected. Laboratory diagnosis of all H5N1-positive cases was conducted at the Central Veterinary Diagnostic Laboratory (CVDL) in Riyadh, Saudi Arabia. A combination of diagnostic tests was used to confirm the laboratory diagnosis. A rapid antigen-capture test and real-time reverse transcriptase-PCR (rtRT-PCR) assay on clinical and field specimens were conducted initially. Meanwhile, virus isolation in specific-pathogen-free embryonating chicken eggs was performed and was followed by hemagglutinin (HA) and hemagglutination inhibition tests, then rapid antigen-capture and rtRT-PCR tests on HA-positive allantoic fluid samples. In most HPAI cases, a complete laboratory diagnosis was made within 24-48 hr at the CVDL. Saudi Arabian government officials made immediate decisions to depopulate all H5N1-affected and nonaffected flocks within a 5-km radius area and applied quarantine zones to prevent the virus from s
