Pediatrics inpatients at the King Khalid University Hospital, Riyadh, Saudi Arabia, 1985-1989.  

Science.gov (United States)

A review of admissions into the pediatric wards of the King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia, over a four-year period (1985-1989) indentified perinatal problems, acute respiratory infections, congenital anomalies and diseases of the central nervous system, as the major disorders. With the notable exception of nutritional rickets, manlnutrition was rare. The age distribution showed a preponderance of neonates and infants who represented 42.1% and 53.6% of all admissions, respectively. There was a seasonal variation with more patients being admitted during the cool months of November-April than the hot months of May-October, and acute respiratory infections were found to be mostly responsible for this seasonality. Genetic and heredofamilial factors features prominently in the pathogenesis of many of the disorders for which the children were admitted. It is therefore recommended that increased attention be given to neonatology and to genetics and genetic counselling as important components of medical practice in the country. The establishment of a National Institute for Human Genetics is also highly desirable. PMID:17587999

Traffic Conditions in Emerging University Campuses: King Saud University, Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Universities worldwide face growing problems of traffic congestion and parking shortages due to the increased usage of private automobiles and the decline of public and non-motorized transport systems. This paper addresses transportation system challenges facing university campuses. As a case study, it addresses King Saud University, Saudi Arabia. The fast growth of King Saud University Campus during the last 5 years had profound impacts on its transportation system.The study adopts two methodological approaches. Theoretically it reviews and analyzes several studies and published reports related to KSU campus and other international campuses. The empirical approach emphasizes the analysis of field data gathered by relevant KSU departments. The paper intends to analyze changes in traffic conditions and transportation systems within the KSUC and draw conclusions on the current and future issues facing the campus and other similar campuses. For a more sustainable campus, KSU has to adopt a balanced transportation system. The new system should not be based solely on improving vehicular circulation and parking provisions. It should enhance public transportation and pedestrian environment within the campus. The university should embark new sustainable policies to curtail demand on vehicular trips and parking spaces and increasingly rely on environmental-friendly modes of travel.

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.

Integrated random measurements in King Saud University Girl's Campus,Riyadh, Saudi Arabia  

International Nuclear Information System (INIS)

This residential site consisting of three buildings was chosen because itis highly populated and in the center of the city of Riyadh. The dosimeterswere kept in the buildings for a period of nine months from January toOctober, 2001. The radon average concentration per room in buildings one, twoand three are found as (32+-2) Bqm-3, (40+-3) Bqm-3 and (59+-6) Bqm-3respectively. In this study a consisted trend of high radon concentration insmall rooms than large ones may indicate poor ventilation in small rooms. Thestatistical analysis shows that 75% of the values are equal or less than 50Bqm-3. It is also seen that 98% of the measured values are less than the safelimit of 148 Bqm-3 set by the Environmental Protection Agency of the U.S.A.It can therefore be concluded that these buildings may have no potentialhealth hazard of Radon.

Maternal mortality in Riyadh, Saudi Arabia.  

Science.gov (United States)

The maternal mortality in the Maternity and Children Hospital, Riyadh, during the years 1978-1980 was 52 per 100 000 births, when the total births were 55 428. This is higher than the rate reported from the hospitals in developed countries but lower than rates reported by the university hospitals of developing countries such as India, Thailand and Nigeria. Haemorrhage, associated disease, pulmonary embolism and infection, in that order, were the main causes of maternal deaths. The main avoidable factor was failure by the patient to seek the medical care. Much could be done in reducing deaths due to haemorrhage by improving blood transfusion facilities in the peripheral hospitals. Adequate health education, especially of rural women and their midwives, is a crucial factor in improving the maternal death rate for the country as a whole. PMID:6615737

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.

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.

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives : A national plan of management for flu-like illnesses was developed by the Saudi Ministry of Health after the first outbreak in Saudi Arabia in June. We describe the clinical presentation of the H1N1 cases attending King Khalid University Hospital (KKUH between July through September 2009 and identify the high-risk age groups. Methods : All patients presenting with influenza-like illnesses (ILI in the H1N1 clinics during the specified period were clinically examined and tested using reverse transcription polymerase chain reaction (RT-PCR. Those who were clinically diagnosed and confirmed positive for novel influenza A (H1N1 were included in the study. Results : Over a 6-week period, 117 cases of laboratory-confirmed cases were reported in KKUH with a mean (SD age of 19.6 (16.7 years, of whom 72 (62.1% were males. Most reported cases were Saudis (n=99, 85.3%; 94 (81% had no travel history outside the country; 100 (86.2% had had no contact with an H1N1-identified patient; 33% were aged 5-14 years and 28.4% were aged 15-29 years. The most commonly reported symptoms were fever in 99 (85.3%, cough in 9 (81%, runny nose (33.6% and sore throat (21.3%. All 117 cases were confirmed positive using real time RT-PCR testing. Thirty-one cases (26% were admitted and 22 of those (71% recovered after receiving oseltamivir. Two deaths were attributed to the 2009 pandemic. One patient died of chronic pulmonary disease. The other cause of death was unknown. Conclusion : These findings indicate indigenous influenza A (H1N1 transmission, and confirm the urgent need for prevention strategies which specifically target children and young adults, who appear to have a higher risk of infection and hospitalization. Such measures include immunization, improved personal hygiene, and increased ventilation in habitations.

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.

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.

Minor surgery at primary care centers in Riyadh, Saudi Arabia.  

Science.gov (United States)

This study was conducted to review the present situation with regard to training, facilities and performance of minor surgical procedures in primary care, and to look at the way doctors perceive various minor surgical procedures in primary care. Randomly selected primary care doctors working in Riyadh health centers completed a predesigned confidential questionnaire, which was then mailed to the researchers. The questionnaire of data on health centers, such as geographic location, size of catchment area population and number and gender of doctors working there. In addition, demographic data of doctors who completed the questionnaire, as well as their exposure to minor surgery training and performance, were recorded. The doctors were then asked about their perception of the necessity of performing various minor surgical procedures in primary care centers. The study was conducted from June through December of 1994. The completed questionnaires were entered into a personal computer for statistical analysis using the chi-squared test. Of the 231 doctors who participated in the present study, 74% performed some sort of minor surgery during their day-to-day work in the health center. Doctors living in remote areas performed more minor surgery (MS) compared to other areas and male doctors performed more MS than female doctors (P = 0.05). As doctors gained confidence in certain skills such as resuscitation, venous cut-down and handling of trauma and fractures, they performed more MS compared to those who were not confident. A room allocated for MS only was available to 27.7% of doctors, but instruments and equipment were available for over 76% of doctors. The doctor's perception of the necessity for MS was statisticaly higher among MS performers only in cases of removal of benign skin lesions, sebaceous cysts and treatment of burns, compared with non-MS performers. There is a great need for provision of facilities and organized training courses in minor surgical procedures for primary care doctors and nurses. PMID:17429237

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

Body Mass Index and Dietary Intake of Saudi Adult Males in the Riyadh Region-Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

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.

Knowledge and practice of spirometry among pediatricians in Riyadh, Kingdom of Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Spirometry is the most basic, widely used and effort-dependent pulmonary function test. It assesses the lung volumes and flows, and is ideally suited to describe the effects of restriction or obstruction on lung function. Therefore, keeping in view the clinical applications of spirometry, this study attempts to explore the knowledge and practice about spirometry among pediatricians. Materials and Methods: A questionnaire-based study was conducted across multiple centers in various hospitals in Riyadh, Saudi Arabia. The structured questionnaire, based upon knowledge and practice of spirometry, was distributed to 150 pediatricians in the various tertiary care hospitals in the metropolitan area of Riyadh. Results: Ninety-four percent of 113 pediatricians agreed that spirometry is a valuable tool in pediatric clinical practice. However, knowledge relating to spirometry was lacking among pediatricians, and about 86% of the study population did not demonstrate up-to-date knowledge of spirometry in pediatrics. Only 11% of pediatricians were very confident in interpreting spirometry results. No statistically significant association was observed between the distribution of responses relating to knowledge and practice of spirometry and the study variables including academic position, duration of practicing experience and number of patients attended daily. Conclusion: The results indicated that pediatricians in Riyadh were lacking adequate knowledge about the clinical applications of spirometry in their daily clinical practice. Hence, it was suggested that pediatricians should attend periodical training, workshops and continuous medical education programmes to enhance their knowledge. This should especially be performed during their pediatric residency training programmes, as spirometry is one of the essential components in clinical practice.

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.

Science.gov (United States)

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

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.

Full Text Available Abdullah Mohammed Al-Bedah1, Naseem Akhtar Qureshi21Arabian Center for Tobacco Control, 2General Administration for Medical Research and Mental Health and Social Services, Ministry of Health, Riyadh, Saudi ArabiaBackground: Tobacco use is a major public health problem, and its prevalence is globally increasing, especially among children and adolescents.Objective: The Global Youth Tobacco Survey aimed to explore the epidemiological trends and risk factors of tobacco smoking among intermediate school boys in Riyadh region of the Kingdom of Saudi Arabia.Method: A two-stage cluster sample design was used to produce a representative sample of male students from selected schools. The participants (n = 1830 self recorded their responses on the Global Youth Tobacco Survey questionnaire.Results: Lifetime prevalence of cigarette smoking was 35%, while 13% of students currently used other tobacco products. About 16% of students currently smoked at home, and 84% of students bought cigarettes without any refusal from storekeepers. Thirty-one percent and 39% of students were exposed to secondhand tobacco smoke inside and outside the house, respectively, which was definitely or probably harmful to health as opined by 87% of participants, and 74% voiced to ban smoking from public places. Among current smokers, 69% intended (without attempt to quit and 63% attempted (but failed to quit during the past year. Almost an equal number of students saw antismoking and prosmoking media messages in the last month, and 28% of students were offered free cigarettes by a tobacco company representative. In schools, more than 50% of students were taught about the dangers of cigarette smoking in the last year. Smoking by parents, older brothers, and close friends, watching prosmoking cigarette advertisements, free offer of cigarettes by tobacco company representatives, perception of smoking being not harmful, and continuing smoking which can be easily quit significantly increased the odds of smoking by students.Conclusion: The common use of tobacco in school populations needs to be addressed by, among other tobacco control measures, a strict ban on cigarette selling to minors and intensive regular tobacco control campaigns involving health and religious messages.Keywords: tobacco use, secondhand tobacco smoke, environmental tobacco smoke, intermediate school boys, Global Youth Tobacco Survey, Saudi Arabia

Hydrochemical and quality of water resources in Saudi Arabia groundwater: A comparative study of Riyadh and Al-Ahsa regions  

Directory of Open Access Journals (Sweden)

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

International Nuclear Information System (INIS)

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

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)

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

Science.gov (United States)

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

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

The present status of geography education in boys' intermediate schools of Riyadh, Saudi Arabia  

Science.gov (United States)

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

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.

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

Clinical aspects and frequency of scorpion stings in the Riyadh Region of Saudi Arabia.  

Directory of Open Access Journals (Sweden)

The high prevalence of scorpion stings largely with mild signs/symptoms and without any mortality suggests the predominance of weak venomous scorpion species in the Riyadh region. Therefore, the protocol of managing scorpion-sting patients with anti-venom irrespective of the intensity of manifestations warrants a detailed review.

Directory of Open Access Journals (Sweden)

Full Text Available This study aimed to evaluate what impact service quality that underlies the SERVQUAL model has on customer satisfaction in Saudi Arabia’s banking sector. The study was quantitative in nature and involved distributing a structured, pre-tested, self-administered questionnaire that was based on a convenience method to 412 customers of various bank in the Saudi capital city of Riyadh, during the fall of 2014. The response rate was 67 percent and the study data was analyzed using SPSS and a reliability coefficient (alpha was determined. Regression analysis found a positive relationship among assurance, empathy, and responsiveness, but that this relationship has no significant effect (P?0.50 on customer satisfaction. Reliability was found to have a negative relationship to customer satisfaction, but no significant effect on the same. Only tangibles were found to have a positive relationship and a significant impact (P?0.50 on customer satisfaction. The results show that, in the retail banking sector, the servqual model remains an effective way of measuring customer satisfaction. Because customer value is an asset to organizations, organizations must ensure that they provide the right products and services, supported by the right promotion, at the right time for their customers.

Science.gov (United States)

Osteoporosis is a growing chronic health problem that could result in mortalities and poor living quality. This study aimed at assessing the awareness of adults in Riyadh about this disease and its associated factors as well as compare KAP levels of men and women. A cross sectional study including 505 participants was conducted in several malls of Riyadh city during March 2012, selected by stratified random sampling technique. Self-administered questionnaire was used for data collection. 86% of the participants had heard of osteoporosis. Media was the main source for Participants' knowledge; the mean knowledge score was 56.6% of the maximum achievable score. There was significant differences in knowledge scores by educational level, employment, income and residence (P = 0.005), (P = 0.008) (P = 0.0122) and (P = 0.009), respectively. Participants had low frequencies of preventive practices, especially females who had a mean total score equivalent to 48.8% of the maximum score, while males' mean score was 54.7% (P = 0.000). Perceived susceptibility was higher among females (83 vs. 74%, P = 0.000), and thus had less perception of the barriers to preventive actions, than men (49.6 vs. 55.5%, P = 0.000). Self-efficacy and perceived benefits had the highest scores (95% of the maximum achievable scores). Considerable number of adult males and females are unaware about osteoporosis. Since there is deficiency in the knowledge, and poor application of the preventive actions. Therefore, Education programs are needed to improve awareness and motivating healthy behaviours.

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.

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.

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.

PHYSICIANS’, NURSES’ AND PATIENTS’ PERCEPTION WITH HOSPITAL MEDICAL RECORDS AT A MILITARY HOSPITAL IN RIYADH, SAUDI ARABIA  

Science.gov (United States)

Background: A medical record contains data on patients to support current and continuing patient care. Medical Records Department has the traditional role of keeping the patient's records safe. This is the first attempt in the Kingdom, to the best of our knowledge, to assess the feasibility of introducing electronic medical records. Objective: The aim of the study was to assess the views of physicians, patients and nurses of medical records services and physicians’ views on the use of electronic medical records. Methods: The study was conducted with physicians, nurses and patients selected randomly from the Military hospital in Riyadh. The data was collected via a self- administered, pilot-tested, internally consistent questionnaire. Results: On the staff of medical records, the highest mean score was obtained for confidentiality (2.92), and the lowest for the training of medical staff (1.88). On medical record documents, the highest mean score was reported for “information is confidentially maintained” (2.70), and the lowest for the organization of files within file sections (2.28). On the Medical Records Department, the highest mean score was reported for overstaffing (2.89), and the lowest for receptiveness of receptionists (2.27). Physicians had low scores for computer literacy, ranging from 1% for prior computer experience to 27% for owning a computer. Physicians were not enthusiastic about the change to electronic medical records. Conclusions: Despite the observed shortcomings of the existing medical records system, it is not expected that medical records would be computerized in the near future since physicians have not accepted this technology wholeheartedly.

Performance of men and women medical students at King Saud University, Riyadh: a 10-year retrospective study.  

Science.gov (United States)

This study was carried out using the results of medical students at the College of Medicine at King Saud University, Riyadh between 1975 and 1985. The purpose of the study was to ascertain whether any correlation existed between school performance and college performance, whether results from males were different from results from females, and whether the semester system, in operation since 1981, produced different results from the annual system. Significant correlations were found between school Grade Point Average (GPA) results and college results, being highest for premedical courses and lowest for clinical courses. However, these correlations were too small to be of practical use. Men students were found to perform better at preclinical subjects whereas women had better results at clinical subjects. The overall performance on the semester system was significantly higher than that on the annual system. PMID:3626905

High prevalence of osteoporosis in Saudi men  

International Nuclear Information System (INIS)

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

Methodology: As a comparator, a cross-sectional survey involving 76 Saudi residents from different training centers in Saudi Arabia namely; Riyadh, Jeddah, Medina, Abha, and Dammam and 15 Canadian. Results: The results showed that Canadian residents read more peer-reviewed, scholarly articles compared with Saudi residents (P=0.002. The primary surgical role for residents was to hold retractors during surgery. The survey respondents strongly supported the ability to recommend removal of incompetent trainers. Saudi trainees were more apprehensive of examinations than Canadian trainees (P<0.0001. Most residents preferred studying multiple-choice questions before examinations. Saudi and Canadian participants considered their programs to be overcrowded. Unlike Canadian participants, Saudi trainees reported an inadequate level of training (P<0.0001. Conclusion: Educational resources should be readily accessible and a mentorship system monitoring residents' progress should be developed. The role of the resident must be clearly defined and resident feedback should not be ignored. Given the importance of mastering basic orthopedic operative skills for residents, meaningful remedial action should be taken with incompetent trainers.

The Value and Attributes of an Effective Preparatory English Program: Perceptions of Saudi University Students  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigates the effects of gender and geographical location on the perceptions of Saudi university students regarding the value of preparatory English programs and their attributes. Data was collected during the fall of 2013 from three sample universities in the Kingdom of Saudi Arabia (KSA using an online survey as the instrument. Participants in the study (N = 479 were all enrolled in similar preparatory year English programs in the kingdom and totaled one hundred eighty-four male students and two hundred ninety-five female students. Encouraging results from this study suggest that Saudi university students do realize the value of a preparatory year English program. In most cases, they share common perceptions about which attributes are needed to insure the success of any such program. In some cases, there are significant differences based on gender and geographical location. While research studies on the specific language skills of Saudi university students are increasing steadily each year, the number of studies on preparatory English programs in Saudi Arabia is limited. This study marks the first kingdom-wide, large-scale quantitative analysis study on the programs themselves.

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.

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

Full Text Available 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.

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 thies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and cardiac diseases in 6 (5.8%). Six patients (5.8%) had moyamoya syndrome, which was associated with another disease in all of them. Inherited metabolic disorders (3.8%) included 3 children with Leigh syndrome and a 29-months-old girl with mitochondrial encephalomypathy, lactic acidosis, and stroke-like episodes. Systemic vascular disease was a risk factor in 3 children (2.9%) including 2 who had hypernatrmic dehydration; and post-traumatic arterial dissection was causative in 3 cases (2.9%). Several patients had multiple risk factors, whereas no risk factor could be identified in 11 (10.6%). Due to high prevalence and importance of multiple risk factors, a comprehensive investigation, including hematologic, neuroimaging and metabolic studies should be considered in every child with stroke.

EFL Teachers’ Perceptions, Evaluations and Expectations about English Language Courses as EFL in Saudi Universities  

Directory of Open Access Journals (Sweden)

Full Text Available The focus of this study is to explore EFL teachers’ perceptions, evaluations and expectations about English language courses as EFL in Saudi tertiary level. In other words, this article aims at creating a new avenue for effective EFL teaching-learning curriculum techniques and syllabus in the Saudi tertiary context. Saudi universities offer credit and non-credit Foundation English courses as a part of their program, which are not being very effective. These courses do not promote the students in dealing with their disciplines or programs oriented courses. Even after completion of the Foundation English courses in consecutive two or three semesters, students fail to grasp comprehensive control over the reading materials of their discipline-oriented courses. This is a common scenario in almost all the universities in KSA. The author of this paper ventured to study the predicament of EFL courses in some universities through survey questionnaires, observation as well as primary and secondary sources. The data were collected through questionnaires from a total of 25 EFL teachers at renowned Saudi universities. The research results revealed that the existing Foundation English Course syllabus is not tailored appropriately to the needs of the students so far as the higher studies concerned, and EFL classroom is not conducive to task-based language teaching (TBLT practice due to large class size (100-140. It, therefore, suggests that university Foundation English Courses should be redesigned in assimilating the learners’ standard and previous learning, and course contents should cover the socio-cultural factors of the learners. The study also concludes with some effective implications and recommendations based on the findings of the present research.

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.

Slight differences emerged in the Saudi Arabia and Gulf States universities’ stakeholders’ use of email in terms of having email, frequency of checking email, and skills in using email. The Saudi Arabian universities must improve their IT infrastructure, including the provision of suitable connection networks and formal training of staff in utilising IT resources. This study’s findings aim to advise the Saudi Arabian and Gulf States’ universities on their plans and programmes for e-learning and the consolidation of required resources.

Attitudes of students and employees towards the implementation of a totally smoke free university campus policy at King Saud University in Saudi Arabia: a cross sectional baseline study on smoking behavior following the implementation of policy.  

Science.gov (United States)

Tobacco smoking is the preventable health issue worldwide. The harmful consequences of tobacco smoking and exposure to second-hand tobacco smoke are well documented. The aim of this study is to compares the prevalence of smoking among students, faculty and staff and examines their interest to quit. Study also determines the difference on perceptions of smoking and non-smoking students, faculty and staff with regard to implementation of a smoke-free policy. A cross-sectional survey was administered to one of the largest universities in Riyadh, Saudi Arabia during the academic year of 2013. A Likert scale was used on questionnaires towards attitude to smoking and smoking free policy. The Chi squared test was used to determine the difference of support on completely smoke free campus for smokers and non-smokers. Smoking rates were highest among staff members (36.8 %) followed by students (11.2 %) and faculty (6.4 %). About half of the smokers (53.7 %) within the university attempted to quit smoking. Students (OR 3.10, 95 % CI 1.00-9.60) and faculty (OR 4.06, 95 % CI 1.16-14.18) were more likely to make quit smoking than staff members. Majority of the respondents (89.6 %) were supportive of a smoking--free policy and indicated that should be strictly enforced especially into public places. Results also showed that smokers were more likely to support a smoke-free policy if there are no fines or penalties. These baseline findings will provide information among administrators in formulating and carrying out a total smoke free policy. Although the majority of people within the King Saud University demonstrate a high support for a smoke-free policy, administrators should consider difference between smokers and non-smokers attitudes when implementing such a policy.

Estimation of rainfall using remote sensing for Riyadh climate, KSA  

Science.gov (United States)

Rainfall data constitute an important parameter for studying water resources-related problems. Remote sensing techniques could provide rapid and comprehensive overview of the rainfall distribution in a given area. Thus, the infrared data from the LandSat satellite in conjunction with the Scofield-oliver method were used to monitor and model rainfall in Riyadh area as a resemble of any area in the Kingdom of Saudi Arabia(KSA). Four convective clouds that covered two rain gage stations were analyzed. Good estimation of rainfall was obtained from satellite images. The results showed that the satellite rainfall estimations were well correlated to rain gage measurements. The satellite climate data appear to be useful for monitoring and modeling rainfall at any area where no rain gage is available.

The Relationship between Saudi English Major University Students’ Writing Performance and Their Learning Style and Strategy Use  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigates the link between writing tasks, learners’ learning style preference, and writing strategy use. It also investigates if students with various proficiency levels stem from different learning style preference and use different writing strategies. This research attempts to answer the following research questions: what are the most common learning style preferences of Saudi undergraduate students majoring in English? what are the most common writing strategies used by Saudi students when writing an essay? Is the choice of writing strategy related to a learner’s learning style preference and writing task, and how might they be linked with one another? And finally does the use of writing strategies contribute to students’ writing performance? The sample of the study consisted of 74 Saudi female undergraduate students in their final year of their bachelor degree in King Abdulaziz University, Saudi Arabia. Two questionnaires were used: (a the Perceptual Learning Style Preference by Reid (1987, and (b a writing strategy questionnaire by Petri and Czárl (2003. Moreover, students were asked to choose one of the two TOEFL writing prompts to write an essay. The data received from the returned questionnaires and writing tests were analysed using descriptive and inferential statistics using SPSS19. Results indicated that Saudi female students were mostly auditory and group learners. As for the writing strategies, Saudi learners used more “before writing” strategies than “during writing” strategies and “reviewing writing” strategies. Results revealed that there was no correlation between the participants’ learning style preference and writing strategies, nor their use of writing strategies and their writing proficiency. As a whole, this study contributed to the ESL/EFL field by providing information on Saudi undergraduate female learners in terms of their preferred perceptual learning style, their level of writing proficiency, and indeed their use of writing strategies.

Influence of Adiposity-Related Genetic Markers in a Population of Saudi Arabians Where Other Variables Influencing Obesity May Be Reduced  

Science.gov (United States)

Large scale studies in Europeans have clearly identified common polymorphism affecting BMI and obesity. We undertook a genotype study to examine the impact of variants, known to influence obesity, in a sample from the Saudi Arabian population, notable for its profound combination of low mean physical activity indices and high energy intake. Anthropometry measures and genotypes were obtained for 367 Saudis, taken from King Saud University and Biomarker Screening Project in Riyadh (Riyadh Cohort). We observed large effect sizes with obesity for rs10767664 (BDNF) (OR = 1.923, P = 0.00072) and rs3751812 (FTO) (OR = 1.523, P = 0.016) in our sample and, using weighted genetic risk scores, we found strong evidence of a cumulative effect using 11 SNPs taken predominantly from loci principally affecting appetite (OR = 2.57, P = 0.00092). We used conditional analyses to discern which of our three highly correlated FTO SNPs were responsible for the observed signal, although we were unable to determine with confidence which best marked the causal site. Our analysis indicates that markers located in loci known to influence fat mass through increased appetite affect obesity in Saudi Arabians to an extent possibly greater than in Europeans. Larger scale studies will be necessary to obtain a precise comparison. PMID:25484485

Methods: A cross-sectional survey using a questionnaire, anthropometric measurements, and laboratory assessments was conducted from January to May 2011 on 194 randomly selected Saudi medical students at Taibah University, Madinah, Kingdom of Saudi Arabia. The adequacy of nutrient intake was compared with the recommended daily intake (RDI per the National Research Council. Results: Caloric intake was derived from carbohydrates (72.1%, fats (19.4% and proteins (8.4%. Proteins and fats were obtained from a greater number of animal sources than of plant sources (5.3% versus 3.2% for proteins and 11.6% versus 7.8% for fats. There were low percentages of RDI of fibers (8.5%, most vitamins especially vitamin D (14.2%, and minerals (potassium (31.3%, zinc (40.7%, magnesium (24.5%, and calcium (47%. Overall, 34.5% of the students were overweight, and 10.3% were obese. Dyslipidemia was diagnosed in 24.7%, and 56.2% had high high-sensitivity C-reactive protein (hs-CRP. There was a positive correlation between the median caloric intake and both the BMI (r=0.42, p=0.00 and hs-CRP (r=0.3, p=0.001. Inactivity was prevalent among the students (64.4%. Conclusion: This study showed deficiencies in several essential nutrients among medical students, and the prevalence of overweight status, obesity, and inactivity were relatively high. These results indicate the need to improve nutrition and promote healthy lifestyles among the medical students.

However, no similar study has investigated this issue among patients diagnosed with major depressive disorder in Saudi Arabia. The aim of this study is to explore patients’ adherence to antidepressant medications, and the factors associated with adherence.Methods: A non-experimental cross-sectional design was used to measure adherence to antidepressants among major depressive disorder patients, and the factors associated with adherence. The patients were recruited from the outpatient clinic at the Al-Amal Complex for Mental Health in Riyadh, Saudi Arabia, between August 2013 and January 2014. Eligible participants met with one of the research coordinators for assessment of their adherence. Adherence was investigated indirectly by use of the Morisky Medication Adherence Scale, and patients’ beliefs were assessed through the Beliefs about Medicine Questionnaire. Information about the severity of their depression, demographics, and other study variables were collected.Results: A total of 403 patients met the inclusion criteria and participated in the study. Of those, 203 (50.37% were females, while the remaining 200 (49.6% were males. There was an average age of 39 years (standard deviation, ±11 years. Half of the patients (52.9% reported low adherence to their antidepressant medication, with statistically significant differences between the low adherence and high adherence scores relating to sex, age, and duration of illness. Conclusion: Low medication adherence is a common problem among major depressive disorder patients in Saudi Arabia. Medication-taking behavior among depressed patients is influenced by several factors, mainly patients’ beliefs regarding antidepressants. This study has improved the understanding of the factors associated with adherence to antidepressants.

Directory of Open Access Journals (Sweden)

Full Text Available Mohammed Al-OmranThe Peripheral Vascular Disease Research Chair and Division of Vascular Surgery, Department of Surgery, College of Medicine, King Saud University, Riyadh, Saudi ArabiaPurpose: Atherosclerotic disease (AD is the leading cause of death worldwide and in Saudi Arabia. Intensive risk reduction therapy plays a major role in reducing adverse cardiovascular outcomes in patients with AD. The level of awareness of this important fact amongst physicians (family physicians, general internists, cardiologists and vascular surgeons in managing these patients in Saudi Arabia is not currently known. This study was conducted to examine the perceptions and knowledge of risk reduction therapy in patients with AD amongst physicians in Saudi Arabia in two clinical presentations; coronary artery disease (CAD and peripheral artery disease (PAD.Materials and methods: We conducted a cross-sectional self-administered survey of 897 physicians at different hospitals in four provinces in Saudi Arabia.Results: The recommended targets of low density lipoprotein-cholesterol (LDL-C, blood glucose, and blood pressure in patients with CAD and PAD were known as 40% and 36%; 70% and 66%; and 32% and 28% of physicians, respectively. The initiation of antiplatelet medications, angiotensin converting enzyme (ACE inhibitors, statins, and nicotine replacement therapy for smokers in patients with CAD and PAD were recommended by 98% and 97%; 52% and 34%; 61% and 56%; and 50% and 43% of physicians, respectively. Compared to other specialties, cardiologists had the lowest threshold for initiating risk reduction therapy, whereas vascular surgeons had the highest threshold.Conclusion: The level of physician awareness of atherosclerosis risk reduction therapy across Saudi Arabia has revealed knowledge and action gaps. A call to action to implement effective strategies to encourage health professionals to use risk reduction therapy and increase public awareness is needed.Keywords: coronary artery disease, peripheral arterial disease, risk reduction, atherosclerosis

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 ave died or kept their follow-up, had one or more occurrences, one month to 5 years after initial stroke (median 23 months). Patients who had recurrent strokes were significantly more likely to be the product of consanguineous marriages (p=0.04). Regarding the group of 23 children with perinatal stroke, neither deaths nor recurrences occurred during the follow-up period. However, 20 (87%) of them had significant delays in their developmental milestones. The toll of stroke in Saudi children is demanding, with most children demonstrating persistent neurologic or cognitive deficits. Primary prevention for recurrences is feasible through informed genetic counseling. (author)

Ethernet TCP/IP based building energy management system in a university campus in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

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 higtice 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)

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.

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

International Nuclear Information System (INIS)

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

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 protective factors for breast cancer and that knowledge and practice of BSE and mammography vary according to marital and educational status. Hence, frequent community based awareness programs are needed so that all women can know and practice BSE, which in turn helps to prevent breast cancer. (author)

Full Text Available  Objectives: To evaluate vitamin D levels in Saudi newborns utilizing umbilical cord samples, and to benchmark the results with international figures. Methods: This cross-sectional study was carried out at King Khalid University Hospital, Riyadh, Saudi Arabia between November 2013 and March 2013. Vitamin D levels were assessed in the umbilical cord of healthy term neonates born above 2.5 kg from healthy pregnant mothers.  Gestational age (GA, birth weight, gender, levels of sun exposure, and consumption of vitamin D rich food data were collected. Our primary outcome was the percentage of newborns with vitamin D deficiency (vitamin D level below 25 nmol/l.  Association of vitamin D deficiency with sun exposure and consumption of vitamin D rich food was tested using a Chi-squared test.Results: Umbilical samples of 200 newborns were obtained. The average birth weight was 3.2 kg. Deficient vitamin D levels were detected in 59% of the sample. Almost 90% of included newborns had vitamin D levels below 50 nmol/l. We found no association of vitamin D deficiency status to level of sun exposure or to consumption of vitamin D rich food. Conclusion: Vitamin D deficiency is very common in Saudi newborns at hospital, and is consistent with regional data. Efforts to assess and treat vitamin D deficiency during pregnancy and provide adequate supplementation to newborns are necessary to rectify such a public health concern.

Quality of informed consent for invasive procedures in central Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Mostafa A Abolfotouh, Abdallah A AdlanKing Abdullah International Medical Research Center, King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi ArabiaBackground: Informed consent is considered the most important step in clinical interventions. The aims of this study were (1 to assess the quality of informed consent for invasive procedures with regard to consent process and information given about risks and alternative treatments, and (2 to determine patients' attitude toward informed consent at King Abdulaziz Medical City, Riyadh, Saudi Arabia.Methods: A cross-sectional study was conducted of 162 adult patients in different wards after undergoing surgery or invasive procedures within 1–2 days of signing the informed consent, using a previously validated interview questionnaire. Data on patients' characteristics, type of invasive procedure, and some informed consent-related issues were collected. Multiple linear regression analysis was used to identify the predictors of the percentage mean score of quality of informed consent, and significance was considered at P ? 0.05.Results: The quality of informed consent was generally poor (% mean score = 50.98 ± 17.49. About two-thirds of patients were told during the informed consent process that they have to sign merely as routine, 48% thought that if they refused the treatment plan they would lose the interest of the treating physician to help them, 42% thought that by saying no they would lose the good relationship with their physician, and 42.6% were not interested in having a copy of the informed consent document. Significantly higher quality was predicted when the physicians were the ones who explained the informed consent (t = 4.15, P < 0.001 and when informed consent was explained to younger patients (t = 2.754, P = 0.007. The overall attitude of the patients toward the process of informed consent was satisfactory (% mean score = 76.31 ± 7.63.Conclusion: The results suggest either that patients are not aware of their rights or that physician paternalism is practiced in Saudi Arabia. Cultural barriers should not be an argument to diminish the role of informed consent. Further studies should focus on how the value of autonomy can be appreciated in the Saudi culture.Keywords: informed consent, quality, invasive procedure, Saudi Arabia

Full Text Available 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

Analysis of such awareness could help to improve the future of IR in Saudi Arabia. Methods: This cross-sectional study was based on anonymous surveys administered over a one month period (1st - 31st  December 2012.  One hundred and nineteen medical students and interns of King Khalid University, Abha, Saudi Arabia were included. Forty-two (35.3% replies were received. The survey consisted of 25 questions covering perception, knowledge, and interest of interventional radiology. Results: The majority of the respondents (52% felt their knowledge in IR is poor. Only 40% of the respondents either completed or plan to complete an elective rotation in radiology. Thirty-eight percent of respondents were willing to consider a career in IR. The most common reason (43% for not considering a career in IR was lack of knowledge. Only 33% correctly identified the route of training of interventional radiologist. The majority of respondents thought that interventional radiologists performed cardiac angioplasty (81%, and femoral popliteal bypass (74%. Conclusion: Exposure to IR among medical students and interns was poor. This can be addressed by dedicated undergraduate teaching of IR by interventional radiologists with emphasis on the clinical practice.

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.

Emerging frontiers of pharmacy education in Saudi Arabia: The metamorphosis in the last fifty years.  

Science.gov (United States)

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

International Nuclear Information System (INIS)

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

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 (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.

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

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 mbined deficiency of 2 or more inhibitors (9/70, 12.9%). Activated protein C resistance has not been detected. Contrary to the findings of previous studies from Saudi Arabia, SCD is a common risk factor and is severe, as it resulted in multiple strokes. Moyamoya syndrome was diagnosed in 2 patients with SCD, one of whom had revascularization surgery (encephaldoduroarteriosynangiosis). Assessment of children with SCD at a risk of stroke was helped by the introduction of TCD followed by neuroimaging, using MRI and magnetic resonanceangiography. The study strongly highlights the importance of prothrombotic disorders and the severe phenotype of SCD as risk factors for stroke in Saudi children. (author)

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.

Directory of Open Access Journals (Sweden)

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

Saudi Arabia: World Oil Report 1991  

International Nuclear Information System (INIS)

This paper reports on the Saudi Arabian Oil Co. (Saudi Aramco), the only operator in the country, that has accelerated its production expansion program aimed at boosting capacity from the current 8.5 million bpd to 10 million bpd. Initially expected to be completed by 1999, it now appears a sustainable 10 million bpd rate may be attainable by 1996. By this time next year, at least nine major onshore projects will have been started as well as five offshore. Included will be development of Hawtah, the initial oil discovery in the Central province south of Riyadh. The program also means significantly increased drilling. In fact, 1991 completions should easily double those of last year

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

Science.gov (United States)

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 Mössbauer spectroscopy as raw clay fraction and after being fired at 950-1,000 °C. The Mössbauer 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.

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

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)

Advancing adolescent health and health services in Saudi Arabia: exploring health-care providers' training, interest, and perceptions of the health-care needs of young people  

Directory of Open Access Journals (Sweden)

Full Text Available Fadia S AlBuhairan,1–3 Tina M Olsson3,4 1Department of Pediatrics, King Abdulaziz Medical City, Riyadh, Saudi Arabia; 2King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia; 3King Abdullah International Medical Research Center, Riyadh, Saudi Arabia; 4School of Social Work, Lund University, Lund, Sweden Background: Adolescent health is regarded as central to global health goals. Investments made in adolescent health and health services protect the improvements witnessed in child health. Though Saudi Arabia has a large adolescent population, adolescent health-care only began to emerge in recent years, yet widespread uptake has been very limited. Health-care providers are key in addressing and providing the necessary health-care services for adolescents, and so this study was conducted with the aim of identifying opportunities for the advancement of knowledge transfer for adolescent health services in Saudi Arabia. Methods: This Web-based, cross-sectional study was carried out at four hospitals in Saudi Arabia. Physicians and nurses were invited to participate in an online survey addressing their contact with adolescent patients, and training, knowledge, and attitudes towards adolescent health-care. Results: A total of 232 professionals participated. The majority (82.3% reported sometimes or always coming into contact with adolescent patients. Less than half (44%, however, had received any sort of training on adolescent health during their undergraduate or postgraduate education, and only 53.9% reported having adequate knowledge about the health-care needs of adolescents. Nurses perceived themselves as having more knowledge in the health-care needs of adolescents and reported feeling more comfortable in communicating with adolescents as compared with physicians. The majority of participants were interested in gaining further skills and knowledge in adolescent health-care and agreed or strongly agreed that adolescents have specific health-care needs that are different than children or adults (82.3% and 84.0%, respectively. With respect to health services, the majority (85.8% believed that adolescents should be hospitalized in adolescent-specific wards. Only 26.7% of health-care providers believed that patients should be transferred from child to adult health-care services at 12–13 years of age, as is currently practiced in the country. Conclusion: A gap exists between the training, knowledge and skills of health-care providers, and the needs to address health-care issues of adolescents in Saudi Arabia. This coupled with the fact that health-care providers are interested in gaining more knowledge and skills and are supportive of changes in the health-care system provides an opportunity for building local capacity and instituting medical and nursing education and health-care reform that can better serve the needs of the country's young population.

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.

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, whichur children (17%) had low protein C, which was associated low protein S and raised anticardiolipin antibodies (ACA) in one patient, and low antithrombin III in another. Low proteins S was detected in a 42-month-old boy. The abnormality in the sixth child was confined to raised ACA. The present study highlights the non-specific features by which stroke presents during the neonatal period. The data are in keeping with the potential role for inherited and acquired thrombophilia as being the underlying cause. However, the high prevalence of additional acquired antenatal and perinatal risk factors support a multifactorial disorder. (author)

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.

Science.gov (United States)

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

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

Language Maintenance and Language Shift among Second Generation Tigrinya-speaking Eritrean Immigrants in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This paper addresses the language maintenance and language shift among the young Tigrinya-speaking Eritrean immigrants in Riyadh, Kingdom of Saudi Arabia. Sixty-four Tigrinya-speaking teenager immigrants in Riyadh participated in this study. Forty of them are females and twenty-four are males. These respondents are students enrolled in the Eritrean International School in Riyadh. The results reveal that respondents have a limited ability to understand, speak, read, write, and translate orally Tigrinya into Arabic and vice-versa. In comparing the level of their proficiency in both Tigrinya and Arabic, it is found that they have a lower proficiency in Tigrinya than in Arabic. The use of Tigrinya is seemingly decreasing and the use of Arabic is increasing. Therefore, there is evidence from this study that second-generation Tigrinya teenagers’ proficiency is shifting toward Arabic rather than maintaining the native language.

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

International Nuclear Information System (INIS)

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

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.

Directory of Open Access Journals (Sweden)

Full Text Available The prevalence of obesity is increasing worldwide at an alarming rate in both developing and developed countries. It has become a serious epidemic health problem, estimated to be the fifth leading cause of mortality at global level. This study was designed to determine the prevalence of obesity among students at Umm Al-Qura University in Makkah, Saudi Arabia and to investigate some of the epidemiologic risk factors contributing to it. A cross sectional study was conducted during the academic year 2009-2010. The study included 224 randomly selected students enrolled at Umm Al-Qura University. Data were collected using a pretested, structured self-administered questionnaire. Weight, height, waist hip ratio and Body Mass Index (BMI were recorded for each student. Statistical analysis was done using SPSS version 16. The prevalence of overweight and obesity among the studied students was 25% (19.2%, were overweight and 5.8% were obese. Factors behind overweight and obesity were; high family monthly income, family history of obesity, eating while bored, depressed and upset. The association between physical activity, dietary factors and obesity were not observed in this study. Our findings suggest the need for strategies and coordinated efforts at all levels to reduce the tendency of overweight and obesity and to promote healthy eating habits in our youth.

Saudi Arabia.  

Science.gov (United States)

In 1985, Saudi Arabia's population stood at 9.6 million, with an annual growth rate of 2.8%. The infant mortality rate was 78/1000 and life expectancy was 60 years. Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development. PMID:12178138

The Incidence Rate of Thyroid Cancer Among Women in Saudi Arabia: An Observational Descriptive Epidemiological Analysis of Data from Saudi Cancer Registry 2001-2008.  

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

Maternal mortality: a twenty-year survey at the King Faisal University Hospital, Al-Khobar, Eastern Saudi Arabia.  

Science.gov (United States)

This was an institutional study of all maternal deaths that occurred among 56422 total births at the King Faisal University Hospital, Al-Khobar, Saudi Arabia, between 1983 and 2002. The underlying cause of each maternal death and potentially avoidable factors were analysed. There were 16 maternal deaths in the hospital during the study period, giving a maternal mortality rate of 28.4/100,000 births. The leading cause of death was haemorrhage in seven (43.75%) patients, followed by pulmonary embolism in four (25%) and general anaesthesia in two (12.5%) mothers. The risk factors noted were maternal age 35 years and parity 5 coupled with iron deficiency anaemia. The main avoidable factors were failure of the patients to seek timely medical care and to follow medical advice. More than half the number of direct obstetrical causes of death was thought to be preventable. A rapidly changing attitude of women towards childbirth is occurring through progressively increasing female education and community health programmes in the region. Further reduction of maternal mortality rates in the community is envisaged through greater patient acceptance of medical advice, family spacing and proficient obstetric services. PMID:15203620

Transmission and evolution of the Middle East respiratory syndrome coronavirus in Saudi Arabia: a descriptive genomic study  

Science.gov (United States)

Summary Background Since June, 2012, Middle East respiratory syndrome coronavirus (MERS-CoV) has, worldwide, caused 104 infections in people including 49 deaths, with 82 cases and 41 deaths reported from Saudi Arabia. In addition to confirming diagnosis, we generated the MERS-CoV genomic sequences obtained directly from patient samples to provide important information on MERS-CoV transmission, evolution, and origin. Methods Full genome deep sequencing was done on nucleic acid extracted directly from PCR-confirmed clinical samples. Viral genomes were obtained from 21 MERS cases of which 13 had 100%, four 85–95%, and four 30–50% genome coverage. Phylogenetic analysis of the 21 sequences, combined with nine published MERS-CoV genomes, was done. Findings Three distinct MERS-CoV genotypes were identified in Riyadh. Phylogeographic analyses suggest the MERS-CoV zoonotic reservoir is geographically disperse. Selection analysis of the MERS-CoV genomes reveals the expected accumulation of genetic diversity including changes in the S protein. The genetic diversity in the Al-Hasa cluster suggests that the hospital outbreak might have had more than one virus introduction. Interpretation We present the largest number of MERS-CoV genomes (21) described so far. MERS-CoV full genome sequences provide greater detail in tracking transmission. Multiple introductions of MERS-CoV are identified and suggest lower R0 values. Transmission within Saudi Arabia is consistent with either movement of an animal reservoir, animal products, or movement of infected people. Further definition of the exposures responsible for the sporadic introductions of MERS-CoV into human populations is urgently needed.

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 ventriculfied 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)

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 eved 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.

Spatial autocorrelation of cancer incidence in Saudi Arabia.  

Science.gov (United States)

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

Norms for hand grip strength in children aged 6-12 years in Saudi Arabia.  

Science.gov (United States)

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

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-m100300) 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)

Directory of Open Access Journals (Sweden)

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

The Construction of Identity in L2 Academic Classroom Community: A Small Scale Study of Two Saudi MA in TESOL Students at North American University  

Directory of Open Access Journals (Sweden)

Full Text Available Second language (L2 classrooms are venues for learners to construct their identities, which are socially, culturally, politically and historically situated. Informed by the theory of community of practice (COP, this paper examines how two Saudi first-year students who are pursuing their master degree in TESOL at American Universities shape and negotiate their identities (i.e., participation and membership in their new academic communities, mainly in a L2 academic classroom. The data was collected through (1 a personal narrative which traces each student’s firs-year experience and view toward American oriented classroom participation, and (2 an individual interview to explore in-depth information missing in the narrative accounts. The findings suggest that both Saudi students experienced difficulties and challenges in negotiating competence, identities, and power relations, which was crucial for them to participate and be accepted as legitimate and competent members of their classroom communities. Based on these findings, this paper argues that newcomers’ (i.e., international students socialization in a certain academic discourse community is conflictual and complex process, which involves struggle, negotiation and construction and deconstruction of identities. Possible implications for instruction are discussed.

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 hyperteno 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.

Ability of Saudi mothers to appropriately and accurately use dosing devices to administer oral liquid medications to their children  

Directory of Open Access Journals (Sweden)

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

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

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%.

Subjects and Methods: Pap smear and HPV-16/18 DNA detection by PCR followed by Southern blotting was performed on 120 subjects (Saudi and other Arab nationals during routine gynecological examination.Some HPV-positive subjects were followed for 4 years, by Pap smear every 6 months and by HPV DNA detection at the end of 4 years. Results: Overall HPV-16/18 prevalence was 31.6%. HPV-16 prevalence alone was 13.3%, HPV-16 as a mixed infection with HPV-18 was 15%, and all HPV-16 was 28.3%. HPV-18 alone was 3.3%, HPV-18 as a mixed infection with HPV-16 was 15%, and all HPV-18 was 18.3%. Ten subjects had cervical abnormalities with the Pap smear test, six of whom were HPV-16/18 positive, 1 with HPV-16, 1 with HPV-18, and 4 with a mixed infec-tion of HPV-16/18. Of all 23 HPV-16/18-positive subjects, either as individual or mixed infection, followed for 4 years, 7 showed abnormal cytology, 6 at initial examination and 1 during follow-up. Of these 7, 6 reverted to normal without treatment and 1 was treated and became normal after 3 years. None of the subjects progressed to CIN-III. Conclusion: A high prevalence of HPV-16/18 was found, but with a low rate of progression to CIN. A signifi-cant association with abnormal cytology was found only in patients with HPV-16/18 mixed infection.

International Nuclear Information System (INIS)

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

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.

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To determine the percentage of deaths in the pediatric intensive care unit (PICU attributed to do not resuscitate (DNR orders, and to compare our DNR practice with the international experience. Methods: Retrospective chart review of all children less than 14 years of age who died in the PICU at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia from January 2007 to June 2009 (n=154. Results: The main mode of death was attributed to DNR  orders in 79 cases (51%, failed cardiopulmonary resuscitation in 60 cases (39%, and brain death in 15 cases (10%. Of the 79 DNR orders, 46 (58% were related to withdrawal of life support measures. Conclusion: The DNR is the most common cause of death in the PICU in tertiary hospitals in Saudi     Arabia. To minimize the suffering of the dying child, life support limitation should be considered for children with terminal or untreatable diseases with low chances of survival.

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.

Knowledge and Attitude of Saudi Health Professions’ Students Regarding Patient’s Bill of Rights  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

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 pres 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)

Correlation of Hormone Receptors with Her-2 Neu Protein Expression and the Histological Grade in Invasive Breast Cancers in a Cohort of Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

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 surgee appendicitis especially for junior surgeons.

Calculation of sky turbidity in the Kingdom of Saudi Arabia  

Science.gov (United States)

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

Status of medical liability claims in Saudi Arabia  

International Nuclear Information System (INIS)

With the evolution of health services in Saudi Arabia, there has been increase in the number of medical practice litigations. The author analyzed the medical malpractice litigation that was referred to the National Medico-Legal Committee (MLC) in order to evaluate the magnitude and underlying factors of the problem in Saudi Arabia. A retrospective analysis of the official records of Medico-Legal malpractice over the period 1420H-1424H (199-2003) was performed. The incidence among different medical specialties, location, and final resolution of each claim were identified. Data analysis revealed an increasing trend in the total number of claims over the study period, with a sharp increase in the transition between 1422H and 1423H (2001-200). The distribution of claims over different medical specialties showed that obstetrical practice took the lead with 27%, followed by general surgery and subspecialties, represented by 17% each, internal medicine 13%, while pediatrics contributed 10% of claims: the fewest claims were in dentistry with 2.5%. The majority of claims were referred to the Ministry of Health and private sectors medical facilities. Most claims were from the Riyadh region over the period between 1420H to 1422H (1999-2001), while thereafter, during 1423 and 1424H (2002 and 2003), the Holy Capital had the highest number of claims referred to the MLC. Adherence to standards of medical practice is by far the best approach to avoid or reduce the incidence of litigato avoid or reduce the incidence of litigation. (author)

Medication administration errors in Eastern Saudi Arabia  

International Nuclear Information System (INIS)

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

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.

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.

Hyperlipidaemia in Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol >=5.2 mmol/l) and hypertriglyceridemia (HT) (total triglycerides >=1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipidemia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating problem habits and increasing physical activity are of considerable importance to our community. (author)

An Introduction to Student Quality Circle at College of Business Administration, Salman bin Abdulaziz University, Al Kharj, Kingdom of Saudi Arabia—An Empirical Study  

Directory of Open Access Journals (Sweden)

Full Text Available Catch’em young for imparting hands-on rigorous academic training. This is what has been relentlessly pursued while dealing with the undergraduate students of business management who are to be thoroughly exposed to the whole gamut of quality work life. Whether they opt for corporate career or pursue masters or choose be an entrepreneur, their exposure to the dynamics of quality management must be ensured most likely at student level. Needless to say that the student is more adaptive to change of attitude, behavior, learning etc., and is prone to imbibing the changes without any resistance. One of the collaborative approaches gaining popularity globally is the Student Quality Circle (SQC, an initiative for raising the bar of quality learning and quality teaching. To the best of our knowledge, Quality Circle very much in the vogue, does exist at scores of manufacturing units in Kingdom of Saudi Arabia but this has not yet taken roots in the academic field. This research is essentially a pilot study done at College of Business Administration, Salman bin Abdul-Aziz University, Al-Kharj. The concept “student’s quality circle” has been proved quite effective to a larger extent and its encouraging findings will prompt other colleges to opt for it. The study has done an objective analysis of pre and post session implementation of student quality circle and it has carefully measured its empirical impact on student’ s traits, attitude, learning, extracurricular activities, individual versus team chemistry, leadership, incubation of quality mind set, total quality environment, and student faculty relationship etc.

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 Cas 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)

Symptomatic gallstones: A disease of young Saudi women  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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 outcto 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)

Profile of cancer in Riyadh Armed Forces Hospital.  

Science.gov (United States)

The relative frequency of malignant disease varies with sex, age, race and geographic location. The frequency differs among the developed and developing countries. A review of the first 5000 histologically confirmed malignancies seen at the Riyadh Armed Forces Hospital Oncology Department confirmed differences from those encountered elsewhere. With the absence of a National Cancer Registry, only relative frequencies can be reported. In this series, gastrointestinal tract cancers were the most frequent, at nearly 18%, with high relative frequency of cancers of the liver and esophagus. Colorectal malignancies were less frequent than in the West. Lymphoma was the second most frequent malignancy at 13% with 2.5:1 ratio of non-Hodgkin lymphoma to Hodgkin disease. In both groups, poor prognostic histological varieties were more frequent than in the West. Breast cancer was the most frequent malignancy in females, accounting for 24% of all female cancers, in spite of the infrequency of the traditional risk factors of nulliparity, late age of first pregnancy, late age of menopause, and high dietary fat consumption. Two-thirds of patients with breast cancer were premenopausal. Other malignancies encountered at a higher frequency than in developed countries include hepatocellular carcinoma and nasopharyngeal cancer. This high relative frequency could be related to the high incidence of viral hepatitis and Epstein-Barr virus infections, respectively. The high relative frequency of oral cavity cancers is presumed to be due to chewing Qat and Shama. Thyroid cancer relative frequency was just over 5%, with a high predominance in females. No obvious etiological factors are identified. The relative frequency of bronchogenic cancer is low at 5%. This is likely to increase with the progressive rise in the habit of cigarette smoking. Skin cancer, on the other hand, is low, presumably due to the traditional dress covering the entire body and the head. PMID:17586889

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. Potenand Saudi international commitments. Potential implications for the petrochemical industry in North America were also identified, in terms of technology transfer and having Saudi Arabia secure the markets in order to meet its commitment to the World Trade Organization. tabs., figs

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 immunos that TMA technology is useful for immunohistochemical analysis of large lymphoma populations.

The Effectiveness of Using the Cooperative Language Learning Approach to Enhance EFL Writing Skills among Saudi University Students  

Directory of Open Access Journals (Sweden)

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

Directory of Open Access Journals (Sweden)

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.

The pattern of Middle East respiratory syndrome coronavirus in Saudi Arabia: a descriptive epidemiological analysis of data from the Saudi Ministry of Health  

Science.gov (United States)

Purpose This study describes the epidemiology of Middle East respiratory syndrome coronavirus (MERS-CoV) in Saudi Arabia. Patients and methods Epidemiological analysis was performed on data from all MERS-CoV cases recorded by the Saudi Ministry of Health between June 6, 2013 and May 14, 2014. The frequency of cases and deaths was calculated and adjusted by month, sex, age group, and region. The average monthly temperature and humidity of infected regions throughout the year was also calculated. Results A total of 425 cases were recorded over the study period. The highest number of cases and deaths occurred between April and May 2014. Disease occurrence among men (260 cases [62%]) was higher than in women (162 cases [38%]), and the case fatality rate was higher for men (52%) than for women (23%). In addition, those in the 45–59 years and ?60 years age groups were most likely to be infected, and the case fatality rate for these people was higher than for other groups. The highest number of cases and deaths were reported in Riyadh (169 cases; 43 deaths), followed by Jeddah (156 cases; 36 deaths) and the Eastern Region (24 cases; 22 deaths). The highest case fatality rate was in the Eastern Region (92%), followed by Medinah (36%) and Najran (33%). MERS-CoV infection actively causes disease in environments with low relative humidity (MERS-CoV is considered an epidemic in Saudi Arabia. The frequency of cases and deaths is higher among men than women, and those above 45 years of age are most affected. Low relative humidity and high temperature can enhance the spread of this disease in the entire population. Further analytical studies are required to determine the source and mode of infection in Saudi Arabia. PMID:25187734

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.

Prevalence of Escherichia coli O157:H7 and Salmonella in Camels, Cattle, Goats, and Sheep Harvested for Meat in Riyadh.  

Science.gov (United States)

Escherichia coli O157:H7 and Salmonella are significant foodborne pathogens that can be found in the feces and on the hides of meat animals. When hides are removed during the harvest process, the carcass and subsequent meat products can become contaminated. Camels, cattle, sheep, and goats are harvested for meat in Riyadh, Saudi Arabia. The prevalence of E. coli O157:H7 and Salmonella are unknown in these animals, and it is assumed that if the animals carry the pathogens in their feces or on their hides, meat products are likely to become contaminated. To this end, a minimum of 206 samples each from hides and feces of camels, cattle, goats, and sheep were collected over the course of 8 months and tested for E. coli O157:H7 and Salmonella. It was found that E. coli O157:H7 was present in feces (10.7, 1.4, 2.4, and 2.4%) and on hides (17.9, 8.2, 2.9, and 9.2%) of cattle, goats, camels, and sheep, respectively. The prevalence of Salmonella was 11.2, 13.5, 23.2, and 18.8% in feces and 80.2, 51.2 67.6, and 60.2% on hides of cattle, goats, camels, and sheep, respectively. The prevalence of E coli O157:H7 was nearly zero in all samples collected in June and July, while Salmonella did not exhibit any seasonal variation. These results constitute the first comprehensive study of E. coli O157:H7 and Salmonella prevalence in Saudi Arabian meat animals at harvest. PMID:25581182

Directory of Open Access Journals (Sweden)

Smoking prevalence is considerably high among our hospital workers. It is not only dangerous for the smokers itself but for the patients who idealize the behavior of hospital staff. Most of the smokers know that smoking is harmful to them as well as others around them but they did not succeed in quitting smoking due to various reasons. Health education combined with help from general practitioners may help to increase the quitting rate among smokers and preventing new smokers from taking up smoking.

Directory of Open Access Journals (Sweden)

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

Directory of Open Access Journals (Sweden)

Full Text Available Automatic license plate recognition systems (LPRcan help reduce the number of traffic violations and make ourstreets safer. In this project we developed an automatic systemthat locates Saudi license plates in a captured image regardlessof the time of day or license plate scale. The proposed systemcan tolerate slight tilting of the license plate. The localizationprocess is fairly complex due to the highly varying nature of thebackground. Good results were obtained using the localizationstage. A second part of the system was developed to segmentand recognize the characters in the located license plate.

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

Capacity building in radiopharmaceuticals: Saudi Arabia experience  

International Nuclear Information System (INIS)

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

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.

Correlation of Hormone Receptors with Her 2/neu Protein Expression and the Histological Grade in Invasive Breast Cancers in a Cohort of Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

Potentiality of Secondary Aquifers in Saudi Arabia: Evaluation of Groundwater Quality in Jubaila Limestone  

Directory of Open Access Journals (Sweden)

Full Text Available Groundwater scarcity in arid regions may hinder development plans and cause many inconveniences for the population and authorities. Saudi Arabia has limited groundwater resources stored in the sedimentary sequence of the Arabian Shelf. Some of these resources were classified as major aquifers, secondary and minor aquifers, and some were considered as aquicludes. The Jubaila Limestone is one of the secondary aquifers of Saudi Arabia. The main purpose of this paper is to evaluate the groundwater resources of the Jubaila Limestone in Riyadh area, with emphasis on groundwater quality. Groundwater was found to occur in fractures and within solution openings of the Jubaila Limestone at depths which range between 19 and 210 m. The transmissivity value was 1.7 × 10–3 to 7.2 × 10–3 m2/s; the storage coefficient was of 1.3 × 10–4. The electrical conductivity for collected water samples ranged between 831 and 7670 µS/cm. The major ionic relationships were Na > Ca > Mg and SO4Cl > HCO3. The groundwater evolves from NaCl dominated at the southern end of the study area, into Ca, MgSO4 water in the north. The main chemical process responsible of this variation was found to be dissolution of anhydrite and gypsum. The groundwater was not found suitable for drinking purposes but can be used by livestock and for some agricultural purposes.

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

Science.gov (United States)

Measurements of 14 polycyclic aromatic hydrocarbons (PAH) have been made in Jeddah, Saudi Arabia, with a view to establishing the concentrations in this major city, and quantifying the contributions of major sources. Particulate and vapour forms have been sampled and analysed separately. The concentrations are compared to measurements from other sites in the Middle Eastern region and are towards the lower end of the range, being far lower than concentrations reported from Riyadh (Saudi Arabia), Assiut (Egypt) and Tehran (Iran) but broadly similar to those measured in Damascus (Syria) and higher than those measured in Kuwait. The partitioning between vapour and particle phases is similar to that in data from Egypt and China, but with many compounds showing a higher particle-associated percentage than in Birmingham (UK) possibly reflecting a higher concentration of airborne particulate matter in the former countries. Concentrations in Jeddah were significantly higher at a site close to the oil refinery and a site close to a major ring road than at a suburban site to the north of the city. Application of positive matrix factorisation to the pooled data elicited three factors accounting respectively for 17%, 33% and 50% of the measured sum of PAH and these are interpreted as arising from gasoline vehicles, industrial sources, particularly the oil refinery, and to diesel/fuel oil combustion.

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.

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.

Status of respiratory care profession in Saudi Arabia: A national survey  

Science.gov (United States)

BACKGROUND: Respiratory care (RC) is an allied health profession that involves assessing and treating patients who have pulmonary diseases. Research indicates that respiratory therapists’ (RT's) involvement in caring for patients with respiratory disorders improves important outcome measures. In Kingdome of Saudi Arabia (KSA), RC has been practiced by RTs for more than 30 years. OBJECTIVE: We sought to investigate the status of the RC workforce in Saudi Arabia in terms of demographic distribution, number, education, and RC service coverage. METHODS: We used a specially designed survey to collect data. A list of 411 working hospitals in KSA was obtained. All hospitals were contacted to inquire if RC is practiced by RTs. Data were collected from hospitals that employ RTs. RESULTS: Only 88 hospitals, 21.4% of total hospitals in the country, have RTs. Out of the 244 Ministry of Health (MOH) hospitals, only 31 hospitals (12.7%) employ RTs. There are 1,477 active RTs in KSA. Twenty-five percent of them, or 371, are Saudis. The majority of the RT workforce (60%) work for non-MOH government hospitals, and almost half the total RTs work in Riyadh province. About 60% of RTs work in critical care settings. RC coverage of critical care was 44.5% of ideal. The overall RT-to-ICU bed ratio was 1:11. The ratio was 1:9 for non-MOH government hospitals, and 1:20 for MOH hospitals. CONCLUSIONS: We report the first insightful data on RC workforce in KSA. These data should be used by educational institutions and health policy makers to plan better RC coverage in the country.

Prevalence of Impacted Molar Teeth among Saudi Population in Asir Region, Saudi Arabia – A Retrospective Study of 3 Years  

Science.gov (United States)

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

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.

Dental caries. A meta analysis on a Saudi population  

Directory of Open Access Journals (Sweden)

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

[The weight of immigration in Saudi Arabia].  

Science.gov (United States)

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

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.

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 anticlinine 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)

Linguistic Analysis of Saudi Pidginized Arabic as Produced by Asian Foreign Expatriates  

Directory of Open Access Journals (Sweden)

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

Effect of consanguinity on birth defects in Saudi women; results from a nested case-control study  

DEFF Research Database (Denmark)

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

Factors associated with adherence to medication among depressed patients from Saudi Arabia: a cross-sectional study  

Science.gov (United States)

Background Several studies have investigated the factors associated with adherence to antidepressants, with inconsistent conclusions. However, no similar study has investigated this issue among patients diagnosed with major depressive disorder in Saudi Arabia. The aim of this study is to explore patients’ adherence to antidepressant medications, and the factors associated with adherence. Methods A non-experimental cross-sectional design was used to measure adherence to antidepressants among major depressive disorder patients, and the factors associated with adherence. The patients were recruited from the outpatient clinic at the Al-Amal Complex for Mental Health in Riyadh, Saudi Arabia, between August 2013 and January 2014. Eligible participants met with one of the research coordinators for assessment of their adherence. Adherence was investigated indirectly by use of the Morisky Medication Adherence Scale, and patients’ beliefs were assessed through the Beliefs about Medicine Questionnaire. Information about the severity of their depression, demographics, and other study variables were collected. Results A total of 403 patients met the inclusion criteria and participated in the study. Of those, 203 (50.37%) were females, while the remaining 200 (49.6%) were males. There was an average age of 39 years (standard deviation, ±11 years). Half of the patients (52.9%) reported low adherence to their antidepressant medication, with statistically significant differences between the low adherence and high adherence scores relating to sex, age, and duration of illness. Conclusion Low medication adherence is a common problem among major depressive disorder patients in Saudi Arabia. Medication-taking behavior among depressed patients is influenced by several factors, mainly patients’ beliefs regarding antidepressants. This study has improved the understanding of the factors associated with adherence to antidepressants. PMID:25378929

Osteoporosis among male Saudi Arabs: a pilot study  

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

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

Barriers to TQM Implementation within a Private Medical Services Organizations in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This paper focuses on the barriers that private medical services organizations have faced while trying to implement Total Quality Management (TQM. The study employed a quantitative methodology involving 220 questionnaires that were validated and structured and consisted of 21 items identifying barriers faced by organizations during the implementation of TQM. Using convenience sampling techniques, we distributed the questionnaires to targeted employees of a four private medical services organization in Riyadh, Saudi Arabia. All statistical analysis was conducted in SPSS version 18 using descriptive data, reliability, and factor analysis to explore the barriers to the implementation of TQM. This analysis showed the most significant barriers to implementation were frequent employee turnover, resistance to change among employees, and a lack of understanding about TQM and a shortage of motivation among management. The results provide new impetus for findings from previous studies and offer human resource practitioners, quality managers, and professionals an opportunity to develop plans that addresses the challenges they face when implementing TQM, as well as intervention strategies with which to minimize the impact these challenges.

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.

Online conductivity monitoring of dialysis adequacy versus Kt/V derived from urea reduction ratio: A prospective study from a Saudi center  

Directory of Open Access Journals (Sweden)

Full Text Available Khalid Al Saran1, Alaa Sabry2, Mamdouh Abdulghafour1, Ahmed Yehia11Prince Salman Center for Kidney Disease, Riyadh, Kingdom of Saudi Arabia; 2Mansoura Urology and Nephrology Center, Mansoura University, Mansoura, EgyptIntroduction: Ad equate delivered dose of solute removal (as assessed by urea reduction and calculation of Kt/V is an important determinant of clinical outcome in chronic hemodialysis (HD patients. This requires both prescription of an adequate dose of HD and regular assessment that the delivered treatments are also adequate. Online conductivity monitoring using sodium flux as a surrogate for urea allows the repeated noninvasive measurement of Kt/V on each HD treatment.Methods: We prospectively studied 17 (9 males, 8 females established chronic HD patients over an eight-week period (408 treatments. A pre- and post-dialyzer measurement of the conductivity is performed by two mutually independent temperature-compensated conductivity cells equipped with Fresenius 4008 S® dialysis machines. Urea reduction was measured (once a week by a single pool calculation using immediate post-treatment sampling. No changes were made to any of the dialysis prescriptions over the study period. Values of calculated Kt/V and simultaneously obtained online Kt/V were compared.Results: There was a statistically significant difference between calculated Kt/V and online Kt/V over the study period. The mean calculated Kt/V was 1.37 ± 0.09, and mean online Kt/V 1.02 ± 0.15 (P = 0.000, calculated Kt/V ? 1.2 was achieved in all our patients while online Kt/V ? 1.2 was achieved in only 17.64 %. Yet there was moderate correlation between calculated Kt/V and online Kt/V (r2 = 0.48.Conclusions: Online conductivity monitoring results underestimates dialysis efficiency compared to calculated Kt/V readings. This difference has to be considered when applying Kt/V to clinical practice.Keywords: Kt/V, hemodialysis, online conductivity monitoring

Insulin-dependent diabetes mellitus in children: Familial and clinical patterns in Riyadh.  

Science.gov (United States)

Type I diabetes mellitus is probably common in Saudi Arabia, but only a small amount of information on the disease is available and most cases reported so far have been type II diabetes mellitus. Type I diabetes was diagnosed in 110 children who were followed at Suleimania Children's Hospital over a five-year period (1985-1989). Saudis represented 74.5% (82/110) of the patients, and 53.6% (59/110) were female. Consanguinity existed in 42.7% (47/110) of the parents. A first-degree family history was positive for insulin-dependent diabetes mellitus in 28.1% (31/110). Mean age at onset was 5.87 years, which is low compared with other ages cited in the literature. Thirty-three patients (30%) were below three years of age at onset. The most common clinical sign was diabetic ketoacidosis, which was seen in 67.2% (74/110). Duration of symptoms before diagnosis ranged from two days to more than two months, with a mean of 18.2 days. Partial remission was seen in 30.9% (34/110). This low percentage is probably due to the young age distribution at onset and perhaps to a different pattern of severity of the disease in our community. Further studies, including opening a local registry, are needed for confirming the incidence and characteristics of the disease in Saudi Arabia. PMID:17588108

Adult depression screening in Saudi primary care: prevalence, instrument and cost  

Science.gov (United States)

Background By the year 2020 depression would be the second major cause of disability adjusted life years lost, as reported by the World Health Organization. Depression is a mental illness which causes persistent low mood, a sense of despair, and has multiple risk factors. Its prevalence in primary care varies between 15.3-22%, with global prevalence up to 13% and between 17-46% in Saudi Arabia. Despite several studies that have shown benefit of early diagnosis and cost-savings of up to 80%, physicians in primary care setting continue to miss out on 30-50% of depressed patients in their practices. Methods A cross sectional study was conducted at three large primary care centers in Riyadh, Saudi Arabia aiming at estimating point prevalence of depression and screening cost among primary care adult patients, and comparing Patient Health Questionnaires PHQ-2 with PHQ-9. Adult individuals were screened using Arabic version of PHQ-2 and PHQ-9. PHQ-2 scores were correlated with PHQ-9 scores using linear regression. A limited cost-analysis and cost saving estimates of depression screening was done using the Human Capital approach. Results Patients included in the survey analysis were 477, of whom 66.2% were females, 77.4% were married, and nearly 20% were illiterate. Patients exhibiting depressive symptoms on the basis of PHQ9 were 49.9%, of which 31% were mild, 13.4% moderate, 4.4% moderate-severe and 1.0% severe cases. Depression scores were significantly associated with female gender (p-value 0.049), and higher educational level (p-value 0.002). Regression analysis showed that PHQ-2 & PHQ-9 were strongly correlated R = 0.79, and R2 = 0.62. The cost-analysis showed savings of up to 500 SAR ($133) per adult patient screened once a year. Conclusion The point prevalence of screened depression is high in primary care visitors in Saudi Arabia. Gender and higher level of education were found to be significantly associated with screened depression. Majority of cases were mild to moderate, PHQ-2 was equivocal to PHQ 9 in utility and that screening for depression in primary care setting is cost saving. PMID:24992932

Developing a Framework for Classroom Lesson Delivery to Improve English Teachers’ Performance in the Foundation Year Programme at a Saudi University  

Directory of Open Access Journals (Sweden)

Full Text Available The current English programme provided to foundation year students at King Abdulaziz University is failing to equip learners with the desired level of English language. This paper assesses the teaching materials and proposes a teaching framework to improve teachers’ lesson delivery. The framework was designed to overcome some of the shortfalls in the mandatory course book series (Headway Plus. The framework adopted Kumaravadivelu’s (2010 principles for lesson delivery: diagnosis, treatment and assessment, and advocates the development of cognitive ability, encourages collaborative learning, problem solving, emphasizes process rather than product, communication skills, and self-inquiry. Fifteen English teachers participated in a pilot study by implementing the new lesson delivery framework over a 14-week course. A peer observation strategy was used to help the teachers reflect on their teaching methods and improve the quality of their teaching. Also, during the last two weeks of the course the head of the English unit and an external observer conducted observations to monitor and assess teachers’ development. The findings of the study revealed the new framework helped teachers improve their lesson delivery and encouraged them to use new teaching techniques such as problem solving and a student-centred approach. However, the results also indicated there was a need for teacher training courses to help teachers understand the principles behind the different teaching methodology. In addition, a cultural factor was found to be influential, as some teachers were reserved about criticizing other teachers’ performance.

Reading Strategy Instruction in Saudi Schools  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Perceived Barriers to Research Publishing in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

Demographic perspectives on Saudi Arabia's development.  

Science.gov (United States)

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

Nutritional disorders in Saudi Arabia: a review.  

Science.gov (United States)

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

DDT and its metabolites are linked to increased risk of type 2 diabetes among Saudi adults: a cross-sectional study.  

Science.gov (United States)

Organochlorine (OC) pesticides have recently been associated with type 2 diabetes in several non-Asian general populations. As there is currently an epidemic of type 2 diabetes mellitus in Asia. The prevalence and incidence of diabetes is increasing rapidly worldwide including many Arab Gulf countries. According to a community-based national epidemiological health survey, the overall prevalence of diabetes mellitus in Saudi adults (age group of 30-50 years) is 23.7 %. A recent study by Al-Daghri et al. (BMC Med 9:76, 2011) reported that the prevalence of diabetes mellitus in the Kingdom of Saudi Arabia (KSA) is 31.6 %. We investigated the associations between OC pesticides and type 2 diabetes in Saudi Arabia using a simple, sensitive, rapid, and selective gas chromatography coupled with mass spectrometry (GC-MS) method that has been recently developed. A total of 280 Saudi adults (136 diabetes mellitus (DM) patients and 144 non-DM controls) were randomly selected from the Riyadh Cohort Study for inclusion. The diagnosis of diabetes was based on established diagnosis and medications taken. Blood dichlorodiphenyltrichloroethane (DDT) and its derivatives were quantified using GC-MS. Residues of DDT and its derivatives were analyzed in serum by means of gas chromatography with a mass spectrometry detector. Associations between DDT exposure and T2DM were analyzed by logistic regression. DDT and its derivatives and serum concentrations of DDT and its derivative DDE showed the strongest and most significant association to type 2 diabetes in both cross-sectional and prospective studies. Associations of DDT and its derivatives varied across different diabetes-related components of the metabolic syndrome. It positively and significantly associated with four of the five of these components especially elevated triacylglycerol, high fasting glucose, high blood pressure, and HOMA-IR but negatively and significantly with HDL. Possible biological mechanisms are discussed. This study confirms previous reports relating organochlorine pesticide (OCP) exposure to diabetes and suggests possible hormonal pathways deserving further exploration. The study will be one of the first to shed light on the associations of serum levels of total DDTs and DDT derivatives among the Saudi Arab ethnicity, and diabetes type 2 chronic noncommunicable diseases are highly prevalent.

Carotid Plaques in Saudi Smokers  

Directory of Open Access Journals (Sweden)

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

Haemoglobin Bart's in Saudi Arabia.  

Science.gov (United States)

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

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To evaluate the health-related quality of life (HRQoL for adolescents with type 1 diabetes mellitus (T1DM. Methods: A cross-sectional study was conducted among 214 adolescents (13-18 years with T1DM at the Diabetes Treatment Center, Prince Sultan Military Medical City, Riyadh, Saudi Arabia from June to September 2013. Respondents were selected by their availability during routine visits to outpatient clinics, and interviewed using the Arabic translated version of the Pediatric Quality of Life Inventory 3.0 Diabetes Module (PedsQL 3.0 DM independently. Results: Female gender, multiple daily injection (MDI, longer duration of T1DM (>7 years, diabetic ketoacidosis (DKA and adolescents with >7 HbA1c level had at least one poor HRQoL outcome. Multivariate linear regression analysis showed that age, treatment type (MDI, DKA, and >7 HbA1c were independent influencing factors for subscale diabetes symptoms, whereas >7 HbA1c was the independent influencing factor for treatment barriers and overall HRQoL. The DKA was the independent influencing factor for the subscale of worry, and female gender was the independent influencing factor for the subscale of communication. Conclusion: Female gender, age, treatment type, >7 HbA1c, and DKA are the strongest determinants for lower HRQoL for at least one subscale of the PedsQL 3.0 DM.

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

International Nuclear Information System (INIS)

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

Non-suicidal self-strangulation among adolescents in Saudi Arabia: Case series of the choking game.  

Science.gov (United States)

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

Computer study for estimation of seasonal energy consumption and selection of air-conditioner in six Saudi Arabian cities  

Energy Technology Data Exchange (ETDEWEB)

A computer model was developed to simulate the building cooling load and the seasonal energy consumption of standard residential sized central air-conditioning systems. The model was first validated by comparing the predicted cooling energy consumption within 10% of the metered value. The validated model was next used to compute the cooling load and seasonal energy consumption for similar 100sqm residences in six cities located in different climatic zones of Saudi Arabia. Simulations showed that the cities of Dhahran and Riyadh required a 17.6kW system to satisfy the cooling load through the year, whereas the defined residence in the cities of Taif, Hail, Jeddah, and Gizan required at 14.1kW system. Our analysis showed that the selected residence in Gizan would consume 23100kWh annually, while a comparable residence located in Dhahran having a more severe summer required only 21500kWh. This difference may be explained by analysis of the weather data which revealed that Gizan required year-round cooling, whereas Dhahran needed cooling for only 283 days during the year. Investigation showed that by selecting the next smaller capacity air-conditioning unit for each location than required to satisfy the load for 100% of the time the annual power consumption may be reduced on an average by 10% with about 7% of the hours during the cooling season when the air-conditioning load may not be satisfied.

Predictors of smoking among male college students in Saudi Arabia.  

Science.gov (United States)

Identifying the predictors of smoking in one of the top cigarette-consuming countries in the world is a vital step in smoking prevention. A cross-sectional study assessed the predictors of smoking in a cohort of male students in 3 universities in Saudi Arabia. A pre-tested, validated questionnaire was used to determine sociodemographic characteristics, academic performance, peers' smoking, and presence of a smoker within the family. Of the 337 participants, 30.9% were current smokers (smoked 1 or more cigarettes within the last 30 days). Lower academic performance (OR = 2.29, 95% CI: 1.02-5.17), peer smoking (OR = 4.14, 95% CI: 1.53-11.3) and presence of other smokers in the family (OR = 2.77, 95% CI: 1.37-5.64) were the significant predictors of smoking status identified using multiple logistic regression analysis. These findings highlight the influence of family and peer pressure in initiating cigarette use among the youth of Saudi Arabia. PMID:24673080

Science.gov (United States)

Purpose This study aimed to examine diabetic patients in Jeddah, Saudi Arabia, regarding their general diabetic and oral health-related awareness and practices, their awareness of the association of diabetes with periodontal disease, and their sources of diabetes-related information. Methods Diabetic patients (n=454) who were receiving care at the diabetes clinic in King Abdulaziz University Hospital, Jeddah, Saudi Arabia, from October 2013 to May 2014, completed a six-part questionnaire assessing their sociodemographic characteristics, general and oral health awareness and practices, and sources of diabetes-related information. Descriptive statistics were used to report the results. Results The responses indicated inadequate health-related practices in the surveyed group: 22.2% brushed their teeth twice daily, 73.6% never flossed their teeth, and while 80.2% visited a physician in the past year, only 12.6% visited a dentist during the same year. Of the respondents, 94.8% reported that they had never received advice on oral hygiene tasks in relation to diabetes from a health professional. Awareness about the diabetes and periodontal disease association was limited: 46.7% knew that diabetics have gum problems more often if their blood sugar stays very high, and only 21.8% knew that gum disease makes it harder to control blood sugar in diabetic patients.

Using the theory of planned behavior to predict infant restraint use in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To determine whether the theory of planned behavior (TPB predicted intent of child restraint system (CRS use among pregnant women in the Kingdom of Saudi Arabia (KSA. Methods: In this cross-sectional study conducted in Dallah Hospital, Riyadh, KSA during June-July 2013, 196 pregnant women completed surveys assessing their beliefs regarding CRS. Simultaneous observations were conducted among a different sample of 150 women to determine CRS usage at hospital discharge following maternity stay. Results: Logistic regression model with TPB constructs and covariates as predictors of CRS usage intent was significant (?2=64.986, p<0.0001 and predicted 38% of intent. There was an increase in odds of intent for attitudes (31.5%, p<0.05, subjective norm (55.3%, p<0.001, and perceived behavioral control (76.9%, p<0.001. The 3 logistic regression models testing the association of the relevant set of composite belief scores were also significant for attitudes (?2=16.803, p<0.05, subjective norm (?2=29.681, p<0.0001, and perceived behavioral control (?2=20.516, p<0.05. The behavioral observation showed that none of the 150 women observed used CRS for their newborn at discharge. Conclusion: The TPB constructs were significantly and independently associated with higher intent for CRS usage. While TPB appears to be a useful tool to identify beliefs related to CRS usage intentions in KSA, the results of the separate behavioral observation indicate that intentions may not be related to the actual usage of CRS in the Kingdom. Further studies are recommended to examine this association.

Serological prevalence of Toxoplasma gondii and its association with abortion in sheep in Saudi Arabia  

Directory of Open Access Journals (Sweden)

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

Saudi experience with classic homocystinuria  

International Nuclear Information System (INIS)

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

Implementation of nuclear desalination in Saudi Arabia  

International Nuclear Information System (INIS)

Most of the Saudi desalination plants are of the multistage flash (MSF) type. These plants are often constructed as a dual purpose installation, producing power and water. MSF plants are considered to be energy intensive, where the energy cost is a major controlling parameter in the overall cost of desalination. Oil price fluctuations affect the cost of desalted water significantly. On the other hand, nuclear power offers price stability in the long term. Nuclear powered desalination provides long term availability of indigenous fuel, as well as long term fuel price stability. It has a minimum environmental impact if compared with other conventional desalination processes. The operational expenses of nuclear desalination are far lower than those of conventional plants. implementation of nuclear desalination in Saudi Arabia is essential where large water requirements exist. The CANDU PHWR is the appropriate type of nuclear reactor for Saudi Arabia. A hybrid reverse osmosis/MSF CANDU PHWR is the candidate system for applying dual purpose nuclear desalination plants in Saudi Arabia. (author)

Career profile of dentists in Saudi Arabia  

International Nuclear Information System (INIS)

The aims of the present survey were to determine whether differences existed between male and female dentists in Saudi Arabia in career development, positions occupied within their employment, and to analyze the effect of different variables on their career development in some of the provinces in Saudi Arabia. A self-conducted questionnaire was distributed among male and female dentists, general practitioners as well as specialists, working at several governmental hospitals in Saudi Arabia. The questionnaires consisted of 40 questions in the format of multiple choices and yes/no answer. Data were analyzed by gender with the significant difference level set at (P < 0.05). The response rate was 40.8% of which 51.9% were females and 48.1% males with 70% of them below 45 years of age. No significant difference was found between males and females in having higher education or additional degrees. The specialty that was highly reported among females was pedodontics and in males, orthodontics. Males were more likely to hold authorized administrative positions (63%), while females held administrative positions which were internally arranged by their departments (57%). Eighty-three percent of female respondents thought that there was favouritism towards males in appointment to administrative positions, while only 5.5% of male respondents reported that there was favouritism to females in occupying the same positions. There was no significant difference between male and female decant difference between male and female dentists in Saudi Arabia with respect to job opportunities, working hours and relationships with their colleagues. In addition, there is evidence of an intensifying determination of female dentists in Saudi Arabia, to pursue their chosen career while coping with the diverse demands of being a professional, a wife and mother.

Differences in prostate cancer detection between Canadian and Saudi populations.  

Science.gov (United States)

Few studies have addressed racial differences in prostate cancer (PCa) detection between Western and Arabian countries, although PCa has a significantly lower prevalence in Arabic populations compared to Western populations. Therefore, an explanation of this difference is lacking. Serum prostate-specific antigen (PSA) is a valuable marker used to select patients who should undergo prostate biopsies, although the manner in which it is used may require adjustments based on the ethnic population in question. We investigated racial differences in the PCa detection rate between Canadian and Saudi populations. A retrospective analysis was performed of data collected prospectively over 5 consecutive years in urology clinics at the McGill University Health Center (MUHC) and King Saud University Hospital (KSUH). Men who had high (>4'ng/mL) or rising PSA levels and a negative digital rectal examination were eligible. A total of 1403 Canadian and 414 Saudi patients were evaluated for the study; 717 and 158 men, median age 64 and 68 years, were included in the MUHC and KSUH cohorts, respectively, P<0.0001). Median serum PSA, prostate volume, and PSA density values were 6.1'ng/mL, 47.3 g, and 0.12'ng · mL(-1) · g(-1), respectively, for MUHC patients and 5.2'ng/mL, 64.5'g, and 0.08'ng · mL(-1) · g(-1), respectively, for KSUH patients (P<0.0001, t-test followed by one-way ANOVA). In addition, the KSUH group had a significantly lower PCa detection rate among patients younger than 60 years of age and with PSA values <10'ng/mL. PMID:23802226

Subacute thyroiditis in Western Saudi Arabia  

International Nuclear Information System (INIS)

The aim of this study is to assess the clinical presentation of 23 patients with subacute thyroiditis (SAT) and the diagnostic value of radionuclear scan. This is a cohort study, which consists of 23 patients with a suspected diagnosis of subacute thyroiditis. The study was carried out in the Endocrinology Clinic, King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between July 2002 and July 2004. Medical charts including age, gender, clinical presentation, systemic symptoms and clinical examination of the thyroid gland were reviewed. Laboratory data included white blood count and its differential count, erythrocyte sedimentation rate (ESR), thyroid function test and thyroid antibodies. The radionuclear scan results were also noted. The mode of therapy provided to patients and the outcome of the treatment during a follow up period of 2 years was reported. Twenty-three adult patients with subacute thyroiditis (15 females and 8 males with a female to male ratio of 1.9:1) were reviewed over a 2-year period. The mean age was 35.8+9.2 years. Eighteen patients (78%) had an upper respiratory tract infection at the initial clinical presentation. Twenty patients (87%) visited an Ear, Nose and Throat specialist for sore throat and abnormal sensation in the throat at least 2 weeks before presentation to the endocrinologist. Two patients were admitted to a medical unit with a diagnosis of fever of unknown origin for 4 weeks. All patients had an elevated free thyrks. All patients had an elevated free thyroxine (35.7+19.8 pmol/L) and suppressed thyroid-stimulating hormone (TSH) (0.043+0.065IU). The radionuclear scan showed either no uptake at all in 12 patients or minimal uptake in 11 patients (0.32+0.55%). Eight patients (35%) received prednisolone therapy alone with an average dose of 30-40 mg daily for 7-8 days; 7 patients (30%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs) only. Eight (35%) patients were treated with both NSAIDs and corticosteroids. Hypothyroidism, with elevated TSH, was observed in 6 (26%) of our patients with positive thyroid antibodies during the first 6 months of follow up. There were no reported cases of recurrent or permanent hypothyroidism in our cohort study. Subacute thyroiditis is an uncommon disease that should be considered in the differential diagnosis of acute anterior neck pain, sore throat and fever especially in patients who do not respond to treatment. In the clinical setting, radioiodine uptake can help exclude other diseases, confirm the diagnosis and expedite the initiation of appropriate therapy to relieve symptoms. (author)

Impact of the March 2009 dust event in Saudi Arabia on aerosol optical properties, meteorological parameters, sky temperature and emissivity  

Science.gov (United States)

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

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.

Advancing mass spectrometry-based clinical proteomics in Saudi Arabia. Establishing a Saudi Proteomics Society.  

Directory of Open Access Journals (Sweden)

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

Rheological characteristics of Saudi crude oil emulsions  

Energy Technology Data Exchange (ETDEWEB)

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

Saudi Aramco describes crisis oil flow hike  

International Nuclear Information System (INIS)

On Aug. 2, 1990, Iraqi forces invaded Kuwait and triggered one of the most severe crises in the world's oil supplies since World War II. Within a few days of the invasion, Iraqi and Kuwaiti oil exports were embargoed, and almost 4.6 million b/d oil of production was removed from world markets. This shortfall amounted to about 20% of total Organization of Petroleum Exporting Countries production at the time and could have proven disastrous to the world's industrial and financial well-being. However, there was no disruption to the major economies of the world. This paper reports that the primary reason for the cushioning of this impact was the massive expansion in production undertaken by Saudi Arabian Oil Co. (Saudi Aramco)

Two important Saudi crude assays updated  

International Nuclear Information System (INIS)

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