Bidirectional ventricular tachycardia (BVT) is a tachyarrhythmia characterized by 180-degree beat-to-beat alteration in the QRS axis. BVT is traditionally known as an electrocardiography (ECG) finding pathognomonic of digitalis poisoning and a hallmark of catecholamine-induced ventricular tachycardia. Apart from digitalis poisoning, aconitine poisoning is the only reported cause of poisoning-related BVT, and no report of caffeine-poisoning-related BVT is as yet available. ⋯ Caffeine acts on the ryanodine receptor to promote calcium release from the sarcoplasmic reticulum, and thus can induce BVT via the same mechanism. Caffeine poisoning can be treated by dialysis. In cases of BVT induced by caffeine poisoning, hemodynamic stabilization can be achieved by emergency dialysis.

Multicenter Study Clinical Trial
The relationship between the severity of pain and stone size, hydronephrosis and laboratory parameters in renal colic attack.
In this study, we investigated the relationship between the severity of pain level and hydronephrosis, hematuria and pyuria presence in the acute renal colic attack and whether there was a correlation between the stone size and inflammatory markers. ⋯ We detected that the pain level was not correlated with the stone size and big stones were not statistically riskier in the hydronephrosis development. However, we think that the risk of complications such as hydronephrosis is higher in the patients whose pain level are higher and the infection may be accompanied by this group.

Randomized Controlled Trial Comparative Study
Flexible nasotracheal intubation compared to blind nasotracheal intubation in the setting of simulated angioedema.
Nasotracheal intubation is rarely performed in the emergency department (ED) but may be required in specific situations such as angioedema. Both blind and flexible nasal intubation (FNI) may be utilized; however, the preferred technique is unknown. ⋯ FNI and blind nasal intubation require similar time to intubation in this simulated model of angioedema.
