We have previously shown that in New York State the initiation of malpractice suits correlates poorly with the actual occurrence of adverse events (injuries resulting from medical treatment) and negligence. There is little information on the outcome of such lawsuits, however. To assess the ability of malpractice litigation to make accurate determinations, we studied 51 malpractice suits to identify factors that predict payment to plaintiffs. ⋯ Among the malpractice claims we studied, the severity of the patient's disability, not the occurrence of an adverse event or an adverse event due to negligence, was predictive of payment to the plaintiff.

Genetic differences in immune responses may affect susceptibility to mycobacterial infection, but no specific genes have been implicated in humans. We studied four children who had an unexplained genetic susceptibility to mycobacterial infection and who appeared to have inherited the same recessive mutation from a common ancestor. ⋯ Four children with severe mycobacterial infections had a mutation in the gene for interferon-gamma receptor 1 that leads to the absence of receptors on cell surfaces and a functional defect in the up-regulation of tumor necrosis factor alpha by macrophages in response to interferon-gamma. The interferon-gamma pathway is important in the response to intracellular pathogens such as mycobacteria.
