Repeat CT after blunt head trauma and Glasgow Coma Scale score 13-15 without neurological deterioration is very low yield for intervention.

PURPOSE: Due to the increase in accessibility of computed tomography (CT), repeat head CT scans are routinely ordered for patients with minor head injuries. The aim of this study is to evaluate the necessity and outcomes of routine repeat head CT in patients with GCS score of 13-15 who presented to the emergency department (ED) of Antalya University Hospital in Turkey with blunt head trauma. METHODS: We retrospectively reviewed the charts of patients with minor head trauma that received initial and repeat head CT results from July 1, 2013 to June 30, 2015. Clinical characteristics of patients were compared for two groups of patients: those with neurological deterioration, and those who had routine head CT not required by change in neurological status. Repeat head CT results were analyzed for radiological worsening and the necessity of a surgical or medical intervention such as craniotomy, ICP monitoring, VP shunt and mannitol or hypertonic saline administration. RESULTS: Of 3578 patients with blunt head trauma, 656 (18.3%) patients had repeat head CT; 449 of these (68.4%) had a GCS score of 13-15. We analyzed 441 patients for CT and clinical changes. Eight patients were excluded because of poor image quality and/or penetrating injury. Neurological deterioration was the reason for repeat head CT in 73 (16.5%) patients Rates of medical (mannitol treatment) or surgical (craniotomy) intervention in this group were 26% (95% Confidence Interval [95% CI], 15.7-36.3%) in contrast to 0.8% (95% CI 0.1-1.7%) in the group of patients with routinely ordered head CT but without clinical deterioration. The following factors were statistically associated with need for intervention: use of anticoagulant or antithrombotic medication, fracture in middle meningeal artery territory, even a single point decrease in GCS score, increased headache, recurrent vomiting, neurological deficit, and finally, changes in repeat head CT. CONCLUSIONS: In patients with minor head injuries, those without neurological deterioration have a very low risk of need for medical or surgical intervention. Routinely ordering repeat head CT scans in this group may not be routinely indicated.

Accuracy of Alvarado, Eskelinen, Ohmann, RIPASA and Tzanakis Scores in Diagnosis of Acute Appendicitis; a Cross-sectional Study.

INTRODUCTION: Many scoring systems have been developed to assist in diagnosis of acute appendicitis (AA). This study aimed to compare the screening performance characteristics of Alvarado, Eskelinen, Ohmann, Raja Isteri Pengiran Anak Saleha (RIPASA), and Tzanakis scores in predicting the need for appendectomy in AA patients. METHODS: Our study prospectively evaluated AA patients that were treated in a tertiary hospital's emergency department. The obtained data were used to calculate Alvarado, Tzanakis, RIPASA, Eskelinen and Ohmann scores. Patients were categorized into two groups according to their histopathological results: positive (PA) and negative appendectomy (NA). The accuracy of different scoring systems in diagnosing AA was investigated. RESULTS: 74 patients suspected to AA with the mean age of 36.68 ± 11.97 years were studied (56.8% male). The diagnosis was histopathologically confirmed in 65 cases (87.8%). Median Alvarado, Tzanakis, RIPASA, Eskelinen and Ohmann scores were significantly higher in patients with positive appendectomy. The area under the curve (AUC), sensitivity, and specificity of Tzanakis score in the cut-off value of 8 were 0.965, 84.4%, and 100%, respectively. For Ohmann and Alvarado scores, these measures were 0.941; 71.9%, 89.9% and 0.938, 60.9%, 89.9%, respectively. Tzanakis scoring system had the best screening performance in detection of cases with AA. CONCLUSION: Tzanakis score is more sensitive and specific than Alvarado, RIPASA, Eskelinen and Ohmann scores in identifying AA patients needing appendectomy.

Priapism associated with pregabalin.

Priapism is defined as a prolonged erection of the penis for at least 4 h without sexual stimulation. It may occur in all age groups. Drugs are the most common cause in adults. A 64-year-old male patient was admitted to the emergency department with painful erection that had lasted for 2 days without sexual stimulation. Our patient had used pregabalin for around 1 year due to neuropathic pain. The dose of the drug was increased as his pain scaled up recently. Approximately 30 cc of dark blood was drained from the corpus cavernosum with an 18 Gauge needle in the emergency department. Cavernous blood aspiration and irrigation resulted in significant recovery and relief. We present this report of priapism associated with pregabalin as it is a rare case with insufficient number of studies in the literature.
