In 2022, an English family court found an unnamed doctor guilty of using thallium in a pot of coffee to kill his partners father and injuring the partner and her mother in 2012. The case is unusual because it was in a family court, arising out of child-custody matters, rather than a criminal case. In fiction
Ngaio Marsh used thallium acetate in her 1947 detective novel, Final Curtain. It was being used legitimately for scalp problems in a group of school children just after World War II, housed in a private estate. A relative living there used it in place of the heart medicine intended for the owner. Agatha Christie, who worked as an apothecarys assistant, used thallium in 1961 as the agent of murder in her detective fiction novel The Pale Horse – the first clue to the murder method coming from the hair loss of the victims. This novel is notable as being credited with having saved at least two lives after readers recognised the symptoms of thallium poisoning that Christie described. The Pale Horse was found among possessions of convicted thallium poisoner George Trepals wife, the orthopedic surgeon Dr. Diana Carr (see above), who was herself considered a suspect in the Peggy Carr (no relation) murder for a time. In Nigel Williams 1990 novel The Wimbledon Poisoner, Henry Far uses thallium to baste a roast chicken in a failed attempt to murder his wife.
In cardiology, hibernating myocardium is a state when some segments
of the myocardium exhibit abnormalities of contractile function. These
abnormalities can be visualised with echocardiography,  cardiac magnetic resonance imaging (CMR), nuclear medicine (PET) or ventriculography. Echocardiography: A wall motion abnormality at rest which improves during a low-dose dobutamine stress test is classified as "hibernating myocardium." Low dose dobutamine stimulates contractile function and thus helps to predict functional recovery after revascularization. Cardiac magnetic resonance: The most frequently used MR contrast agents based on Gd-chelates accumulate in the extracellular space which is increased in scarred myocardium. This leads to a signal increase which can be visualised with the "late gadolinium enhancement technique." This is probably the most accurate way to visualise scarred myocardium. An alternative (or additional) technique with CMR is the use of low dose dobutamine similar to echocardiography. PET: The finding of a perfusion or metabolic mismatch between PET-FDG and PET-NH3 is indicative of decreased metabolism. The wall of the affected segments is hypo-, a-, or dyskinetic.The phenomenon is highly significant clinically because it usually manifests itself in the setting of chronic ischemia, that is potentially reversible by revascularisation via cardiac catheterization. The regions of myocardium are still viable and can return to normal function. There develops a new steady state between myocardial blood flow (MBF) and myocardial function, MBF reduced and in consequence function is reduced too. The clinical situations where one can expect hibernating myocardium are:
chronic stable angina
unstable angina
silent ischemia
after AMI
