Hospital-acquired infections are a serious health problem. One potential source of contamination is through the spread of pathogen-bearing droplets emanating from toilet flushes. The video above includes high-speed flow visualization of the large and small droplets that get atomized during the flush of a standard hospital toilet. Both are problematic for the spread of pathogens; the large droplets settle quickly and contaminate nearby surfaces, but the small droplets can remain suspended in the air for an hour or more. Even more distressing is the finding that conventional cleaning products lower surface tension within the toilet, aggravating the problem by allowing even more small droplets to escape.

(Source: artfund.org)"As in my chapter on the politicization of patienthood, in this chapter on doctors’ narratives I show the possibility of resisting the power/knowledge nexus that Foucault called "biopower," this time from the doctor’s side of the binary. Deleuze and Guattari are interested not only in the ways in which power/knowledge operates but also in the minority discourses (like Foucault’s "subjugated knowledges") that can and do emerge not from beyond or behind the operations of power/knowledge, but from within it. This does not mean, however, that doctors become patients in reality, but that they are constantly becoming-patient through the process of desubjectification (a giving up of their identity as, or only as, doctor within the doctor-patient binary), deterritorialization (a movement away from the institutional spaces and practices of medicine that create distance rather than proximity between doctor and patient), and disarticulation (an unlearning of certain modern medical knowledges and practices cultivated in medical school). I consider the possibility of doctors’ becoming-infected and becoming-affected by their patients; again, not in reality, by HIV itself, but by their patients’ stories."Lisa Diedrich, Treatments: Language, Politics, and the Culture of Illness
Vials of Surfactant TA (Tokyo Akita), a modified sheep lung surfactant, brought back from Tetsuro Fujiwara’s lab at Akita University School of Medicine, Japan, by Mary Ellen Avery. Building off of Avery’s 1959 discovery that the cause of Respiratory Distress Syndrome in infants is the lack of surfactant in the lungs, Fujiwara became the first to successfully treat respiratory distress syndrome using surfactant replacement therapy."Sometimes defining issues as questions of technique or evidence masks the underlying political disputes… . But the political disputes are still there, even when they are addressed indirectly using the language of technique and evidence. Battles over income, turf, and the goals of medicine and policy lie just below the surface. Under these circumstances, evidence becomes an instrument of politics rather than a substitute for it."The Politics of Evidence-Based Medicine, by Marc A.
