Background: The frequency of increased high-sensitivity C-reactive protein (hs-CRP) and the time course of evolution of their levels in patients with acute idiopathic pericarditis (AIP) are not well established.

Objective: To assess the time course of evolution of hs-CRP levels and the possible clinical significance of maximal hs-CRP levels in patients with AIP

Methods: We retrospectively reviewed the medical files of 241 patients admitted to the hospital with a diagnosis of AIP between March 2006 and March 2017. Data on demographics, time of symptom onset, laboratory and imaging findings, and outcome were collected.

Results: Data on serum hs-CRP levels were available for 225 patients (age 18–89 years, 181 men). Fever, pleural effusion, and age were independently associated with hs-CRP levels. Major cardiac complications (MCC) (death, cardiac tamponade, cardiogenic shock, large pericardial effusion, ventricular tachycardia, pericardiocentesis, or pericardiectomy) were more common in patients with hs-CRP levels above the median compared to those below (21.2% vs. 4.5%, respectively, P < 0.001). Hs-CRP levels were independently associated with MCC (odds ratio [OR] 1.071, 95% confidence interval [95%CI] 1.016–1.130, P = 0.011). Hs-CRP levels were elevated in 76.0%, 92.3% and 96.0% of the patients tested <6 hours, 7-12 hours, and >12 hours of symptom onset, respectively (P = 0.003). The frequency of elevated hs-CRP among patients tested > 24 hours was 98.1%.

Conclusions: Hs-CRP levels rise rapidly among patients with AIP. Maximal hs-CRP levels are associated with MCC. A normal hs-CRP level is rare among patients tested > 24 hours of symptom onset.

Background: With the recent introduction of high-sensitivity troponin (hsTn), the incremental benefit of stress myocardial perfusion imaging (MPI) in the evaluation of patients who present to the emergency department (ED) with acute coronary syndrome (ACS) is unclear.

Objectives: To assess the added value of stress MPI in low-risk ACS patients with normal range hsTnI.

Methods: We analyzed all patients who were hospitalized at our medical center from February 2016 to November 2017, who presented with low-risk ACS and underwent stress MPI, and in whom hsTnI was in the normal range after the introduction of hsTnI.

Results: During the study period, 161 patients were admitted with a diagnosis of unstable angina (i.e., ACS with normal range hsTnI) and underwent stress MPI during index admission. The study population included 52/161 patients (31.7%) with low-risk ACS who had no indication for initial invasive strategy. No patients had positive MPI. One patient underwent coronary angiography due to suggestive history; however, he did not have a significant coronary artery disease and had no indication for percutaneous coronary intervention.

Conclusions: In patients with low-risk ACS and normal range hsTnI without additional high-risk features, stress MPI has little additional value for the correct diagnosis and management. Prospective studies are warranted to confirm whether resting hsTnI could serve as a powerful triage tool in chest pain patients in the ED before diagnostic testing and thus, improve patient management.

Background: Fine-needle aspiration cytology (FNAC) is used to provide rapid diagnostic information regarding masses of the head and neck. To achieve good results, adequate training is essential.

Objectives: To evaluate the efficacy of FNAC in the diagnosis of head and neck masses performed by residents and attending physicians.

Methods: Palpable guided FNA biopsies from 166 consecutive patients with head and neck masses, excluding thyroid, who were treated in our department between 2008 and 2010 were retrospectively reviewed. Accuracy, sensitivity, specificity, and positive and negative predictive values were calculated.

Results: A total of 193 FNACs were performed in 161 patients (5 patients were excluded due to age under 18). Mean age was 57.3 years; female to male ratio was approximately 5:4. Most FNACs were performed in masses in the parotid gland (37.3%), 14.5% in the posterior neck, 19.1% in the lateral neck, 15% at level 1, and 9.3% at level 6. The median size of the masses aspirated was 2 cm. Most FNACs were performed by an experienced physician (2.5:1). About 25% of the patients required a second FNAC. Almost 70% of FNACs were diagnostic. Of these, 71.2% were of benign processes and 28.8% of malignancies.

Conclusions: An FNAC of a palpable mass in all sites of the neck, excluding the thyroid, can be done as an office procedure with reasonable results without imaging guidance. About 25% of patients will require another biopsy. The procedure is not difficult to master, as evident by the fact that there were no differences in the results of FNACs performed by an attending otolaryngologist or a resident.

 

Background: The kinetics of high sensitivity cardiac troponin T (hs-cTnT) levels after elective, biphasic, direct-current cardioversion for persistent atrial fibrillation/flutter remains unknown.

Methods: We examined hs-cTnT kinetics in 24 patients at baseline and at 2, 6 and 24 hours post-cardioversion, and again at 7 and 30 days. We also examined levels of creatine kinase, aspartate aminotransferase, lactate dehydrogenase, brain natriuretic peptide (BNP), and high sensitivity C-reactive protein (hs-CRP).

Results: Median (25th, 75th interquartiles) baseline hs-cTnT concentration was 19.8 (10.4, 35.2) ng/L with 14 patients presenting with levels above the 99th percentile (13 ng/L). Hs-cTnT levels did not change significantly over time although they tended to decrease by 30 days, 18.8 ng/L (12.5, 23.3). There was no significant rise in other markers of myocardial injury. Similarly, BNP and hs-CRP levels were elevated at baseline and tended to decrease over time.

Conclusions: Patients with persistent atrial fibrillation/flutter have elevated hs-cTnT levels, as part of a general rise in biomarkers such as BNP and hs-CRP, without a further rise after cardioversion. After cardioversion, there is a gradual non-significant decrease in biomarker levels over time, and thus a rise in hs-cTnT levels should not be attributed to cardioversion. 

 

Background: Although the presence of bacteria in the cervix is not a sign of disease, the majority of pathogens involved in pelvic inflammatory disease originate from this "normal" flora.

Objectives: To assess the distribution of cervical non-gonococcal and non-chlamydial bacteria in hospitalized women with PID[1] and the bacteria's antibiotic sensitivity.

Methods: We retrospectively evaluated the cultures obtained from the uterine cervix over a 1 year period (2008) at Wolfson Medical Center, Holon. The distribution of cervical non-gonococcal and non-chlamydial bacteria in women with PID and the bacteria's antibiotic sensitivity was compared to that in our previous 1 year study that was performed at Kaplan Medical Center, Rehovot (1988–89). 

Results: In 2008, a total of 412 cultures were obtained of which 126 (30.5%) were sterile. The prevalence of negative cultures was similar in 2008 and in 1988, namely, 30.5% and 33.7%, respectively (P = 0.23). PID was finally diagnosed in 116 patients with positive cultures. The most prevalent bacteria in the 2008 study were Enterococcus species and Escherichia coli – 24.0 % and 26.4% respectively compared to 18.0% and 38.1% in the 1988 study, with the decrease in E. coli isolates being significant (P = 0.0003). In 2008 the antimicrobial sensitivity for various antibiotics ranged from 44.3% to 100.0% (median 90.2%) while in 1988 it ranged from 2.9% to 80.1% (median 51.9%).

Conclusions: The cervical bacterial flora in hospitalized women with PID did not vary significantly between 1988 and 2008. However, antimicrobial sensitivity of the isolated bacteria increased dramatically, probably due to a decrease in resistance to antibiotics.
