Incidence of autism in high risk neonatal follow up.

OBJECTIVE: To detect autism spectrum disorder (ASD) cases within the High Risk Neonatal Follow up Program (HRNFP), as an indicator of the prevalence of ASD and associated risk factors in the Kingdom of Saudi Arabia (KSA). METHODS: We conducted this retrospective medical chart review in a tertiary care hospital in Riyadh, KSA. All patients admitted to the HRNFP were seen at 3 years corrected age between January 2012 and December 2013. Patients diagnosed with ASD from the HRNFP were referred to the King Fahad Medical City (KFMC) Autism Program for further assessment. The following potential risk factors for ASD were documented: low birth weight, gestational age less than 33 weeks, and male gender. RESULTS: In 2012, 59 patients were evaluated in the HRNFP. Three cases were diagnosed with ASD, with an ASD incidence rate of 5.1% (95% confidence interval [CI] calculated by adjusted Wald method: 1.2-14.5%). In 2013, 48 patients were evaluated and 2 cases were diagnosed with ASD, with an ASD incidence rate of 4.2% (95% CI: 0.4%-14.8%). The total ASD incidence rate during the 2-year study period was 4.7% (95% CI: 1.7%-10.8%). Factors associated with a higher likelihood of ASD were: male gender, low birth weight, and gestational age less than 33 weeks. CONCLUSION: Compared with the community, the prevalence of ASD was higher in the HRNFP. Further investigation is required to evaluate risk factors.

Tolerability of propofol in Wada testing.

OBJECTIVE: To assess the tolerability of propofol (PF) in Wada test in an Arab population with temporal lobe epilepsy (TLE). METHODS: This observational study with consecutive sampling took place in King Fahad Medical City, Riyadh, Saudi Arabia. Nine consecutive patients with mean (± SD) age of 26 (± 5.8) years, 6 males and 3 females, underwent Wada test between January 2009 and December 2012. Six of them had left TLE, and 3 had right TLE. Each patient received 10 mg of PF in the internal carotid artery (ICA). Right hemispheric injection was followed by left hemisphere injection after 30 minutes. During the procedure, EEG monitoring showed changes within 5-18 seconds of injection as hemispheric delta slowing. Neuropsychological tests were carried out for localization of memory and language. RESULTS: We were able to lateralize speech dominance in 8 patients and memory dominance in 6 patients. Peri-procedural complications included transient euphoria (n=1), transient spasm of ICA (n=1), eye pain (n=1), facial pain (n=1), and generalized tremulousness (n=2). None of the patients exhibited a symptomatic drop in blood pressure. CONCLUSION: We found that PF is well tolerable for the Wada test, with minimally significant complications, although blood pressure should be closely monitored.

An international perspective on behavioral science education in medical schools.

The behavioral sciences are taught in medical curricula around the world. In the current paper psychologists teaching in medical schools in Australia, Mexico, Saudi Arabia, Thailand, the United Kingdom and the United States share their experience and reflections. Whilst direct comparisons between countries are not made, the themes that are evident within and between accounts are instructive. As behavioral scientists around the globe are struggling to maintain a presence in medical education many of the reasons behind this are shared, regardless of the country. Challenges discussed include those related to the impact of unrealized potential contributions of psychologists as health care professionals, teaching of behavioral sciences by other professions, domination of the biomedical model without a corresponding recognition of psychology as science, and modern medical pedagogies such as problem-based learning, which favor biomedicine. Systemic and political barriers over which we as a discipline may have little control are also highlighted.

Initial linguistic and psychometric validation of the Arabic version of Nepean Dyspepsia Index.

OBJECTIVE: To report the initial evaluation of the linguistic and psychometric validation of the Nepean Dyspepsia Index (NDI), as part of the ongoing research of quality of life among dyspeptic patients. METHODS: The Arabic version of the NDI was administered to 158 subjects (54 with non-ulcer dyspeptic [NUD]), 50 with gastro-esophageal reflux disease (GERD) and 54 with no history of gastroenteritis disease), with a mean age of 46.6 and SD 10.7. All subjects answered the Arabic versions of the General Health Questionnaire (GHQ), the Self-Report Questionnaire (SRQ), and the Short Form-12 Quality of Life (QOL) scale. We administered the final translation of the NDI by consensus. The study was conducted in King Fahad Hospital of the University, Al-Khobar, Saudi Arabia, between December 2002 and January 2004. RESULTS: The NDI has shown adequate internal consistency. Cronbach Alpha coefficient ranged between 0.88 to 0.93, and Split-half correlation reliability ranged between 0.82 and 0.94. Correlations between NDI subscales and total scores were high and significant. Adequate Face and content validity was demonstrated by consultation with gastroenterologists and clinical psychologists. Convergent validity was shown in the moderate and significant correlation of the NDI subscales and global index with the indices of the SF-12. Divergent validity was shown in that subscales of the NDI revealed low correlation with scales which measure other dimensions; thus, both QOL subscales and symptom checklist have discriminated patients from non-patients groups (p > 0.01). The factorial structure of the NDI was also examined, and it revealed 4 factors, which is similarly the same with other studies. CONCLUSION: The initial validation of the Arabic version of the NDI has shown that this scale has adequate psychometric and linguistic property and can represent a good addition to health outcome measures in dyspepsia research. Further validation studies are recommended.

The role of psychologists in health care delivery.

Advances in the biomedical and the behavioral sciences have paved the way for the integration of medical practice towards the biopsychosocial approach. Therefore, dealing with health and illness overtakes looking for the presence or absence of the disease and infirmity (the biomedical paradigm) to the biopsychosocial paradigm in which health means a state of complete physical, psychological and social well-being. Psychology as a behavioral health discipline is the key to the biopsychosocial practice, and plays a major role in understanding the concept of health and illness. The clinical role of psychologists as health providers is diverse with the varying areas of care giving (primary, secondary and tertiary care) and a variety of subspecialties. Overall, psychologists assess, diagnose, and treat the psychological problems and the behavioral dysfunctions resulting from, or related to physical and mental health. In addition, they play a major role in the promotion of healthy behavior, preventing diseases and improving patients' quality of life. They perform their clinical roles according to rigorous ethical principles and code of conduct. This article describes and discusses the significant role of clinical health psychology in the provision of health care, following a biopsychosocial perspective of health and illness. Professional and educational issues have also been discussed.
