• Comparison of the skin-to-epidural space distance at the thoracic and lumbar levels in children using magnetic resonance imaging SAUDI JOURNAL OF ANAESTHESIA Wani, T. M., Dabaliz, A., Kadah, K., Veneziano, G., Tumin, D., Tobias, J. D. 2020; 14 (4): 493-497

  Abstract

  Several studies have attempted to estimate the approximate distance from the skin-to-epidural space using different imaging modalities (computed tomography [CT], ultrasound, and magnetic resonance imaging [MRI]) and direct needle measurements. The objective of our study was to compare the distance from the skin to the epidural space (SED) at multiple levels, focusing on T6-7, T9-10, and L2-3 using MRI.After institutional review board (IRB) approval, sagittal T2-weighted MRI images of the spine of 108 children in the age group ranging from 3 months to 8 years undergoing radiological evaluation in the supine position at our institution were analyzed. The SED at T6-7 and T9-10 levels (straight and inclined) and SED at L2-3 (straight) were determined and compared using repeated-measures ANOVA and paired t-tests with a Bonferroni correction for 10 pairwise comparisons (P < 0.005 was considered statistically significant).The average SED (measured straight and inclined) was 18.2 mm and 21.6 mm at T6-7; 18.3 mm and 20.5 mm at T9-10; and 21.8 mm (straight) at L2-3. The repeated-measures ANOVA F-test indicated significant variability in SED (P < 0.001) among the 5 measurements obtained. At the P < 0.005 significance level, corrected for multiple comparisons, the SED (straight) at T9-10 straight was shorter than the other measured distances.The distance from the skin to the epidural space is not constant at various vertebral levels. At the levels measured, it was greatest at the lumbar level and at least at the thoracic level of T9-10. A single predictive formula was not applicable for calculating the approximate SED at all vertebral levels.

• How chloroform anesthesia reached Lowell, Massachusetts: From Simpson's pamphlet to Gladwin's advertisement. Journal of anesthesia history Dabaliz, A. M., Bause, G. S., Gladwin, S. F. 2020; 6 (3): 156-157

  Abstract

  J.Y. Simpson of Edinburgh, Scotland discovered chloroform anesthesia in November 1847. During this time, W.T.G. Morton's agents had been collecting royalties for the use of ether across much of the United States. After reading about the advantages of chloroform as cited in C.T. Jackson's writings in the Boston Daily Atlas, S.F. Gladwin, a dentist in Lowell, Massachusetts, who had been reluctant to pay any ether royalties, demonstrated his independence and opportunism in swiftly adopting chloroform in his practice and publicizing its use through local advertisements.

• Impending Paradoxical Embolism: Perioperative Management and Role of Transesophageal Echocardiography SEMINARS IN CARDIOTHORACIC AND VASCULAR ANESTHESIA Dabaliz, A. M., Arain, F. D. 2020; 24 (4): 328-336

  Abstract

  Impending paradoxical embolism is a rare but potentially life-threatening complication of venous thromboembolism that is usually associated with acute pulmonary embolism and a right to left atrial shunt. Patients may have associated right ventricular pressure or volume overload with subsequent failure. Transesophageal echocardiography is the preferred diagnostic test of choice in this patient group. Definitive management has yet to be clearly defined. However, emergent surgical removal of the entrapped intracardiac blood thrombus may be necessary. In this article, we review a case of impending paradoxical embolism managed surgically and describe the perioperative anesthetic considerations in this patient population, along with the role of intraoperative transesophageal echocardiography.

• Predictive validity of pre-admission assessments on medical student performance INTERNATIONAL JOURNAL OF MEDICAL EDUCATION Dabaliz, A. M., Kaadan, S., Dabbagh, M., Barakat, A. A., Shareef, M., Al-Tannir, M., Obeidat, A., Mohamed, A. A. 2017; 8: 408-413

  Abstract

  To examine the predictive validity of pre-admission variables on students' performance in a medical school in Saudi Arabia.In this retrospective study, we collected admission and college performance data for 737 students in preclinical and clinical years. Data included high school scores and other standardized test scores, such as those of the National Achievement Test and the General Aptitude Test. Additionally, we included the scores of the Test of English as a Foreign Language (TOEFL) and the International English Language Testing System (IELTS) exams. Those datasets were then compared with college performance indicators, namely the cumulative Grade Point Average (cGPA) and progress test, using multivariate linear regression analysis.In preclinical years, both the National Achievement Test (p=0.04, B=0.08) and TOEFL (p=0.017, B=0.01) scores were positive predictors of cGPA, whereas the General Aptitude Test (p=0.048, B=-0.05) negatively predicted cGPA. Moreover, none of the pre-admission variables were predictive of progress test performance in the same group. On the other hand, none of the pre-admission variables were predictive of cGPA in clinical years. Overall, cGPA strongly predict-ed students' progress test performance (p<0.001 and B=19.02).Only the National Achievement Test and TOEFL significantly predicted performance in preclinical years. However, these variables do not predict progress test performance, meaning that they do not predict the functional knowledge reflected in the progress test. We report various strengths and deficiencies in the current medical college admission criteria, and call for employing more sensitive and valid ones that predict student performance and functional knowledge, especially in the clinical years.
