ABSTRACT
Three patients with acute severe neck pain, presented with and without neurological deficits. One patient had severe neck pain followed by autonomic dysfunction, aphagia and dysarthria. She had an vertebrobasilar infarction due to the etiology of a dissection of both vertebral arteries. In one patient with a subarachnoidal bleeding, were the complaints mainly started with severe neck pain. There was no aneurysma found. One patient presented with severe pain in the right side of the neck, shoulders and her right arm. She had a hemiparesis. Because of the suspicion of a cerebral infarction, additional anticoagulation was started. She developed a paraparalysis. Her diagnosis was an acute spontaneous cervical epidural hematoma In a few cases, the presence of solely per-acute neck pain is found as symptom of a subarachnoid hemorrhage. In cases of acute neck pain with alarm symptoms, the patient should be referred to the emergency department.

BACKGROUND: Donation after circulatory death (DCD) is a procedure in which after planned withdrawal of life-sustaining treatment (WLST), the dying process is monitored. A DCD procedure can only be continued if the potential organ donor dies shortly after WLST. This study performed an external validation of 2 existing prediction models to identify potentially DCD candidates, using one of the largest cohorts. METHODS: This multicenter retrospective study analyzed all patients eligible for DCD donation from 2010 to 2015. The first model (DCD-N score) assigned points for absence of neurological reflexes and oxygenation index. The second model, a linear prediction model (LPDCD), yielded the probability of death within 60 min. This study determined discrimination (c-statistic) and calibration (Hosmer and Lemeshow test) for both models. RESULTS: This study included 394 patients, 283 (72%) died within 60 min after WLST. The DCD-N score had a c-statistic of 0.77 (95% confidence intervals, 0.71-0.83) and the LPDCD model 0.75 (95% confidence intervals, 0.68-0.81). Calibration of the LPDCD 60-min model proved to be poor (Hosmer and Lemeshow test, P < 0.001). CONCLUSIONS: The DCD-N score and the LPDCD model showed good discrimination but poor calibration for predicting the probability of death within 60 min. Construction of a new prediction model on a large data set is needed to obtain better calibration.
