Association of acute phase reactants with prognostic scores in community acquired pneumonia.

OBJECTIVE: To investigate the association of C-reactive protein and procalcitonin with commonly used prognostic scoring systems, hospitalisation and mortality in cases of community-acquired pneumonia. METHODS: The prospective study was conducted from April 2014 to April 2015 at the emergency department of Marmara University Pendik Research and Training Hospital, Turkey, and comprised community-acquired pneumonia patients diagnosed according to the British Thoracic Society criteria. Prognosis was estimated using confusion, urea, respiratory rate, blood pressure and age >65, Pneumonia Severity Index-Pneumonia Patient Outcome Research Team score, and severe community-acquired pneumonia scores. Data was analysed using MedCalc 15.8. RESULTS: Of the 203 patients assessed, community-acquired pneumonia was confirmed in 152(74.8%). Procalcitonin had moderate correlation with the three scales used (p<0.001), while C-reactive protein had weak correlation with them (p<0.004). CONCLUSIONS: Both procalcitonin and C-reactive protein levels were found to be correlated with prognostic risk scores.

Analysis of Repeated CT Scan Need in Blunt Head Trauma.

Background. Computed tomography (CT) is a vital tool in the workup of patients with closed head trauma. The aim of this study was to investigate the necessity of serial CT scans in patients with blunt head trauma. Methods. This is a retrospective study analyzing trauma patients between January and June 2012. Data were analysed by using frequencies, Kolmogorov-Smirnov (K-S), and Chi-square tests. Results. Of the total 351 control Head CTs, it was seen there were no different in 346 (98.6%). In CTs of another 3 patients (0.9%), there were increasing or new, in the other 2 (0.6%) there was a decrease in the pathology present. Of 24 (6.8%) patients who had a hemorrhage in the first CT, there was an increase in the hemorrhage in one of them, a decrease of the pathology in 2 of them. Of 27 (7.7%) patients who had fracture in first CT, 2 had a new intracranial hemorrhage. The relation of the results between the first and second CTs were statistically significant (P < 0.001, χ (2) test). Conclusion. Repeated CT scans after 6 hours in EDs observation rooms are not necessary if first CT is normal in most situations. Special attention may be needed in patients with an underlying chronic disease.
