72Rotator Cuff Tears Increase With Age and Are Often Asymptomatic
Journal of Shoulder and Elbow Surgery (2014) · Teunis T, Lubberts B, Reilly BT, Ring D
This systematic review pooled data from 30 studies encompassing 6,112 shoulders to determine how common rotator cuff abnormalities are across different age groups. The researchers found that rotator cuff tears become increasingly common with age, rising from 9.7% in people aged 20 and younger to 62% in those aged 80 and older. Crucially, a high percentage of these tears were found in people with no symptoms at all, suggesting that many rotator cuff tears exist without causing pain. The prevalence of asymptomatic tears was high enough that the authors concluded rotator cuff degeneration should be considered a normal aspect of human aging, making it difficult to determine when a tear is new or the actual cause of symptoms.

77Nearly Half of Acetaminophen Liver Failure Cases Are Unintentional Overdoses
Hepatology (2005) · Larson AM, Polson J, Fontana RJ, Davern TJ, Lalani E, Hynan LS, et al.
This prospective multicenter study tracked 662 patients with acute liver failure across 22 tertiary care centers in the United States over 6 years. Of these, 275 cases (42%) were caused by acetaminophen liver injury. The percentage of acetaminophen-related liver failure rose from 28% in 1998 to 51% in 2003. Critically, 48% of these cases were unintentional overdoses, not suicide attempts. The median dose ingested was 24 grams (equivalent to 48 extra-strength tablets). Among unintentional overdose patients, 38% had taken two or more acetaminophen products simultaneously, and 81% reported using acetaminophen for acute or chronic pain syndromes. Overall, 27% of patients died without transplantation and 8% required liver transplants. The study demonstrates that the majority of acetaminophen-induced liver failure is not from intentional self-harm but from people taking too much acetaminophen over time while trying to manage pain. Patients with chronic pain conditions who use acetaminophen for extended periods are particularly vulnerable, as they may unknowingly exceed safe dosing limits by combining multiple products or taking doses that accumulate to toxic levels. These findings support the recommendation that pain relievers should not be relied upon as a long-term strategy for managing soft tissue injuries.
