Background: This study was done to determine variables associated with infectious rhabdomyolysis (IRM).
Methods: In this retrospective case-control study, rhabdomyolysis (RM) was defined as a fivefold or greater elevation in creatine kinase (CK) levels with a muscle/brain (MB) fraction <5%. Patients with myocardial infarction or cerebrovascular accident or a recent history of surgery, trauma, or immobilization were excluded.
Results: We analyzed 52 cases of RM seen at our institution between 1992 and 2000; IRM was the most frequent cause (31%), most commonly respiratory tract infections (38%). When a microorganism could be identified (50%), it was more often gram-negative (63%). Patients with IRM were elderly and had fever and lower CK levels. Infectious rhabdomyolysis was associated with a higher morbidity but not with a higher risk of death.
Conclusions: Infectious rhabdomyolysis is the main cause of RM and must be suspected in elderly patients with fever and low levels of CK.

Several inflammatory myopathies have an infectious or immune-mediated basis in the horse. Myosin heavy chain myopathy is caused by a codominant missense variant in MYH1 and has 3 clinical presentations: immune-mediated myositis, calciphylaxis, and nonexertional rhabdomyolysis in Quarter Horse-related breeds. An infarctive form of purpura hemorrhagica affects numerous breeds, presenting with focal firm, painful muscle swelling, and subsequent infarction of multiple tissues.

Bacillus cereus is a common pathogen responsible for gastrointestinal and other complicated disorders, yet epidemiological data and public health measures remain scarce. To bridge these gaps, a bilingual search spaning 50 years identified 266 relevant studies on global B. cereus infection, encompassing 6,135 cases.

Rhabdomyolysis is a severe condition involving the breakdown of skeletal muscle fibers, leading to the release of muscle components into the bloodstream, which can lead to potential complications such as acute kidney injury and electrolyte imbalances. The etiology of rhabdomyolysis is multifactorial, encompassing traumatic, exertional, metabolic, infectious, toxic, and genetic causes. Genetic causes, including variants in LPIN1, RYR1, and CACNA1S, are increasingly recognized as significant contributors to recurrent rhabdomyolysis.

Article Synopsis
- * Among 231 patients, those with rhabdomyolysis experienced more severe symptoms like confusion and pain, and had higher levels of damage markers for various organs compared to those without rhabdomyolysis.
- * Rhabdomyolysis was linked to a lower survival rate and was identified as an independent risk factor for acute kidney injury and death, highlighting the importance of detecting and treating rhabdomyolysis early in SFTS patients.
