ABSTRACT
Mushroom poisoning with Russula subnigricans can lead to severe rhabdomyolysis. Here we describe a case of severe mushroom poisoning that resulted in severe rhabdomyolysis with acute kidney injury, hypotension, and shock 12 h after oral ingestion of R. subnigricans. The patient's serum myoglobin was 6,475 ng/mL and his creatine phosphokinase (CK) level was 38,100 IU/L on admission. Although aggressive fluid resuscitation and on-line hemodiafiltration (OHDF) were initiated, vascular permeability and shock failed to improve. Continuous hemodiafiltration (CHDF) and OHDF was repeated, but their effects were limited. He later developed generalized edema, and his weight increased from 55 kg to 72.5 kg within 4 days. On day 5, his CK level reached 203,800 IU/L. He died 160 h after oral ingestion of R. subnigricans. CHDF and OHDF filter out circulating myoglobin, potassium, and some toxic substances released due to muscle cell disruption. Although OHDF was performed nearly 24 h a day in our patient, it failed to remove toxic intracellular components from muscle cells due to the severe R. subnigricans mushroom poisoning in this case.
ABSTRACT
A 68-year-old woman had unstable angina pectoris with asymptomatic right internal carotid artery and right middle cerebral artery occlusion with impaired cerebral perfusion reserve. The cardiology, cardiovascular surgery, anesthesiology, and neurosurgery departments discussed the treatment plan. We simultaneously performed superficial temporal artery-middle cerebral artery anastomosis and coronary artery bypass grafting to reduce the likelihood of perioperative ischemic stroke. Fortunately, neither cerebral ischemia nor myocardial ischemia occurred. Simultaneous superficial temporal artery-middle cerebral artery anastomosis and coronary artery bypass grafting can be a therapeutic option for patients with unstable angina and impaired cerebral perfusion reserve. However, the risk of bleeding associated with anticoagulation during coronary artery bypass grafting cannot be ignored.
