Revolt on the Tuberculosis Ward
School of Arts and Sciences
Monique is a 30-year-old Haitian woman with advanced pulmonary tuberculosis who has been transferred from a tuberculosis sanatorium to a large general hospital in Port au Prince after developing a secondary infection with Bacteroides fragilis at the site of her chest tube insertion. The patients on the hospital ward were disgusted by the foul smell of her wound drainage and wanted her removed from the unit. In this directed case, students investigate the characteristics of Mycobacterium tuberculosis and Bacteroides fragilis and review the anatomy and physiology of the respiratory system to help determine whether to keep the chest tube in place or remove it. Using statistics from websites of the World Health Organization, students also must balance the different social, cultural, and medical conditions that exist in Haiti while they formulate a recommendation as to how to end the patient revolt on the tuberculosis unit. Originally designed for use in a general microbiology course, the case could also be suitable for an upper-level pathophysiology or clinical microbiology course.
