Bentazone is a widely used herbicide considered a moderate hazard. Fatalities associated with its use are rare, with deaths reported only after intake of ≥200 mL. In some studies, bentazone intoxication is accompanied by generalized rigidity. Malignant hyperthermia is a pharmacogenetic disease that presents a hypermetabolic response to anesthetic gases or depolarizing muscle relaxants due to calcium channel dysfunction. The classic symptoms of malignant hyperthermia include hyperthermia and muscle rigidity. We report the case of a 65-year-old man who died 4 hours after presenting to the emergency department after ingesting approximately 75 mL of Basagran M60 (bentazone 33.6%, 25.2 g). This is the smallest dose (364 mg/kg) reported in a fatal case to date. Electrocardiogram changes, including QRS widening and QT prolongation, were present, and hypocalcemia was confirmed. We propose that bentazone intoxication causes patient deterioration by a mechanism similar to that of malignant hyperthermia.

Objective
Many studies have examined the July effect. However, little is known about the July effect in sepsis. We hypothesized that the July effect would result in worse outcomes for patients with sepsis. Methods Data from patients with sepsis, collected prospectively between January 2018 and December 2021, were analyzed. In Korea, the new academic year starts on March 1, so the “July effect” appears in March. The primary outcome was 30-day mortality. Secondary outcomes included adherence to the Surviving Sepsis Campaign bundle. Outcomes in March were compared to other months. A multivariate Cox proportional hazard regression was performed to adjust for confounders. Results We included 843 patients. There were no significant differences in sepsis severity. The 30-day mortality in March was higher (49.0% vs. 28.5%, P<0.001). However, there was no difference in bundle adherence in March (42.2% vs. 48.0%, P=0.264). The multivariate Cox proportional hazard regression showed that the July effect was associated with 30-day mortality in patients with sepsis (adjusted hazard ratio, 1.925; 95% confidence interval, 1.405–2.638; P<0.001). Conclusion The July effect was associated with 30-day mortality in patients with sepsis. However, bundle adherence did not differ. These results suggest that the increase in mortality during the turnover period might be related to unmeasured in-hospital management. Intensive supervision and education of residents caring for patients with sepsis is needed in the beginning of training.
