  • Curriculum and Cases for Pain Medicine Crisis Resource Management Education ANESTHESIA AND ANALGESIA Brenner, G. J., Nemark, J. L., Raemer, D. 2013; 116 (1): 107-110


    Medical crises that may occur in the setting of a pain medicine service are rare events that require skillful action and teamwork to ensure safe patient outcome. A simulated environment is an ideal venue for both acquisition and reinforcement of this knowledge and skill set. Here, we present an educational curriculum in pain medicine crisis resource management for both pain medicine fellows and attending physicians as well as the results of a successful pilot program.

  • Correlating virtual reality and box trainer tasks in the assessment of laparoscopic surgical skills AMERICAN JOURNAL OF OBSTETRICS AND GYNECOLOGY Newmark, J., Dandolu, V., Milner, R., Grewal, H., Harbison, S., Hernandez, E. 2007; 197 (5)


    The purpose of this study was to examine the correlation in the assessment of laparoscopic surgical skills in medical students with the use of a virtual reality laparoscopic trainer and a low-fidelity video box trainer with comparative tasks.Third-year medical students were asked to perform 3 basic skills set modules on LapSim (Surgical Science, Gothenburg, Sweden): coordination, grasping and lifting, and handling the intestines. Each task was set at the easiest level, and each student was allowed a maximum of 10 attempts to complete each task. Similar-appearing tasks were chosen for comparison with the use of a standard video box trainer: pegboard, cup drop and rope pass, respectively. Laparoscopic skills were evaluated with the use of both trainers during 1 session. Pearson's correlation coefficients were used to compare paired data on each student using statistical software.Forty-seven of 65 medical students were assigned to clinical clerkships on-campus at Temple University School of Medicine participated in the study. All 47 students participated in the video box trainer tasks; 34 students completed both the video box trainer and LapSim skills set. Observations that were obtained on the LapSim virtual reality system and video box trainer simulator demonstrated several correlations. The time to completion for the LapSim coordination task and the pegboard task were correlated (r = 0.507; P = .006), as were the grasping and lifting task completion time on LapSim and the comparative box trainer cup drop task completion time (r = 0.404; P = .022). When accounting for errors, the LapSim coordination task tissue damage score was correlated with the sum of all box trainer errors (r = 0.353; P = .040); the average grasping and lifting tissue damage was correlated with the total number of errors during all box trainer tasks (r = 0.374; P = .035).Overall, in evaluating laparoscopic skills, the LapSim and video box trainer were correlated positively with one another. The scoring of laparoscopic skills by both systems appears to be equivalent for the measurement of time to task completion and number of errors.

  • Headache Plus: Trigeminal and Autonomic Features in a Case of Cervicogenic Headache Responsive to Third Occipital Nerve Radiofrequency Ablation. Pain medicine (Malden, Mass.) Giblin, K., Newmark, J. L., Brenner, G. J., Wainger, B. J. 2014


    To describe a case of cervicogenic headache with associated autonomic features and pain in a trigeminal distribution, all of which responded to third occipital nerve radiofrequency ablation.Single case report.Massachusetts General Hospital Center for Pain Medicine.A 38-year-old woman with history of migraines and motor vehicle accident.Right third occipital nerve diagnostic blocks and radiofrequency lesioning.Pain reduction; physical findings, including periorbital and mandibular facial swelling, tearing, conjunctival injection, and allodynia; and use of opioid and non-opioid pain medicines.The patient had complete relief of her pain and autonomic symptoms, and was able to stop all pain medications following a dedicated third occipital nerve lesioning.This case illustrates the diagnostic and therapeutic complexity of cervicogenic headache and the overlap with other headache types, including trigeminal autonomic cephalgias and migraine. It represents a unique proof of principle in that not only trigeminal nerve pain but also presumed neurogenic inflammation can be relieved by blockade of cervical nociceptive inputs. Further investigation into shared mechanisms of headache pathogenesis is warranted.

  • Use of video laryngoscopy and camera phones to communicate progression of laryngeal edema in assessing for extubation: a case series. Journal of intensive care medicine Newmark, J. L., Ahn, Y. K., Adams, M. C., Bittner, E. A., Wilcox, S. R. 2013; 28 (1): 67-71


    Video laryngoscopy has demonstrated utility in airway management. For the present case series, we report the use of video laryngoscopy to evaluate the airway of critically ill, mechanically ventilated patients, as a means to reduce the risk of immediate postextubation stridor by assessing the degree of laryngeal edema. We also describe the use of cellular phone cameras to document and communicate airway edema in using video laryngoscopy for the patients' medical records. We found video laryngoscopy to be an effective method of assessing airway edema, and cellular phone cameras were useful for recording and documenting video laryngoscopy images for patients' medical records.

  • Radiocontrast Media Allergic Reactions and Interventional Pain Practice-A Review PAIN PHYSICIAN Newmark, J. L., Mehra, A., Singla, A. K. 2012; 15 (5): E665-E675


    Millions of interventional pain procedures are performed each year in the United States. Interventional pain physicians commonly administer radiocontrast media (RCM) under fluoroscopy for these procedures. However, RCM can cause various types of hypersensitivity or allergic type reactions, in an acute or delayed fashion. Furthermore, some patients report a prior history of hypersensitivity reactions to RCM when presenting to the interventional pain clinic. Both scenarios present challenges to the interventional pain physician.To describe the various types of hypersensitivity reactions to RCM, as well as strategies to prevent and manage these reactions, within the context of interventional pain practice.A review of the literature from 1975 through 2011 regarding allergic type reactions to RCM, as well as iodine, and shellfish allergy, was undertaken in an effort to review and develop recommendations on managing these patients presenting to the interventional pain clinic. Keywords used in the literature search were: radiocontrast media, contrast allergy, contrast reaction, iodine allergy, shellfish allergy, and fluoroscopy. The included articles were concerned with the basic or clinical science of contrast allergy, including the physiology, epidemiology, diagnosis, and management of such reactions. Meta-analysis, review articles, and case reports addressing contrast media reactions were also included. Articles which discussed contrast media reactions in a peripheral fashion were excluded.In reviewing the literature, it is apparent that the mechanisms and pathophysiology of RCM hypersensitivity reactions are still being characterized, which should soon lead to improved screenings, as well as prevention and treatment strategies. Many common themes are described throughout the literature regarding patient risk factors, testing, prevention,diagnosis, and treatment of RCM allergic-type reactions.The current review did not perform a meta-analysis of the available data, as most of the available articles were trials that were randomly controlled. Therefore, the conclusions of the present article are general, and qualitative in nature.Although the mechanisms of various RCM allergic-type reactions are not entirely understood, the interventional pain physician should have a basic understanding of patient risk factors, prevention, diagnosis, and treatment of these reactions. The current review allowed for prevention and treatment strategies for managing patients with RCM hypersensitivity reactions.
