PURPOSE: Although cardiac involvement is an infrequently recognized manifestation of venomous snakebites, little is known of the adverse cardiovascular events (ACVEs) arising as a result of snakebite in Korea. Accordingly, we studied the prevalence of ACVEs associated with venomous snakebites in Korea and compared the clinical features of patients with and without ACVEs. MATERIALS AND METHODS: A retrospective review was conducted on 65 consecutive venomous snakebite cases diagnosed and treated at the emergency department of Wonju Severance Christian Hospital between May 2011 and October 2014. ACVEs were defined as the occurrence of at least one of the following: 1) myocardial injury, 2) shock, 3) ventricular dysrhythmia, or 4) cardiac arrest. RESULTS: Nine (13.8%) of the 65 patients had ACVEs; myocardial injury (9 patients, 13.8%) included high sensitivity troponin I (hs-TnI) elevation (7 patients, 10.8%) or electrocardiogram (ECG) determined ischemic change (2 patients, 3.1%), and shock (2 patient, 3.1%). Neither ventricular dysrhythmia nor cardiac arrest was observed. The median of elevated hs-TnI levels observed in the present study were 0.063 ng/mL (maximum: 3.000 ng/mL) and there was no mortality in the ACVEs group. Underlying cardiac diseases were more common in the ACVEs group than in the non-ACVEs group (p=0.017). Regarding complications during hospitalization, 3 patients (5.4%) in the non-ACVEs group and 3 patients (33.3%) in the ACVEs group developed bleeding (p=0.031). CONCLUSION: Significant proportion of the patients with venomous snakebite is associated with occurrence of ACVEs. Patients with ACVEs had more underlying cardiac disease and bleeding complication.

PURPOSE: Glufosinate poisoning can cause neurologic complications that may be difficult to treat due to delayed manifestation. Studies assessing possible predictors of complications are lacking. Although serum ammonia level is a potential predictor of severe neurotoxicity, it has only been assessed via case reports. Therefore, we investigated factors that predict neurologic complications in acute glufosinate-poisoned patients. MATERIALS AND METHODS: We conducted a retrospective review of 45 consecutive glufosinate-poisoning cases that were diagnosed in the emergency department (ED) of Wonju Severance Christian Hospital between May 2007 and July 2014. Patients with a Glasgow Coma Scale (GCS) score of <8, seizure, and/or amnesia were defined to a neurologic complication group. RESULTS: The neurologic complication group (29 patients, 64.4%) comprised patients with GCS<8 (27 patients, 60.0%), seizure (23 patients, 51.1%), and amnesia (5 patients, 11.1%). Non-neurologic complications included respiratory failure (14 patients, 31.1%), intubation and ventilator care (23 patients, 51.1%), shock (2 patients, 4.4%), pneumonia (16 patients, 35.6%), acute kidney injury (10 patients, 22.2%), and death (4 patients, 8.9%). Complications of GCS<8, seizure, respiratory failure, and intubation and ventilator care appeared during latent periods within 11 hrs, 34 hrs, 14 hrs, and 48 hrs, respectively. Initial serum ammonia was a predictor of neurologic complications [odds ratio 1.039, 95% confidence interval (1.001-1.078), p=0.046 and area under the curve 0.742]. CONCLUSION: Neurologic complications developed in 64.4% of patients with acute glufosinate poisoning. The most common complication was GCS<8. Initial serum ammonia level, which can be readily assessed in the ED, was a predictor of neurologic complications.

Objective:
This study aimed to investigate the biochemical, histologic, and immunologic effects of post-treatment administration of fluvastatin in a hemorrhagic shock (HS) rat model.
Methods:
Experimental rats were randomly divided into four groups: control group: no drugs and did not undergo HS; control statin group: fluvastatin 1 mg/kg (no HS); HS group: normal saline after HS; HS+statin group: fluvastatin 1 mg/kg+normal saline after HS. Briefly, HS was induced by femoral arterial catheter blood extraction of 30% of the total blood volume. The mean arterial pressure and heart rate were monitored for 2 hours after starting blood withdrawal. Arterial blood gas, complete blood count, and serum cytokine levels were measured at baseline, 2 hours after HS, and 48 hours after resuscitation. The kidneys, lungs, and small intestines were removed for pathological examination 48 hours after HS.
Results:
At the end of the resuscitation period, the HS and HS+statin groups showed reduced bicarbonate, base excess, and platelet counts, all of which differed significantly from values in the control and control+statin groups. Compared to the control group, the HS+statin group exhibited significantly elevated serum interleukin-10 (IL-10) at 2 hours after resuscitation (P<0.05). Except for IL-10, the group-time interaction was not significant for other cytokine profiles.
Conclusion
This study demonstrates that post-treatment with fluvastatin after HS increases the production of the anti-inflammatory cytokine IL-10 and affects the cytokine profiles in rats.
