The role of Ottawa ankle rules in geriatric emergency department visits.

BACKGROUND: Ankle injuries are a common reason for visits to the emergency department (ED). An effective diagnosis and treatment process is crucial for the swift recovery of patients and for alleviating congestion in EDs. This study aims to evaluate the adequacy and effectiveness of the Ottawa Ankle Rules (OAR) in geriatric patients presenting to the emergency department (ED). METHODS: Between February 2022 and November 2022, 160 patients aged 65 and older (118 women, 42 men) who presented to the ED with isolated ankle injuries were included in the study. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value of the OAR. RESULTS: The study found fractures in 37.5% of patients. The sensitivity of the OAR was 98.33%, the specificity was 86%, the negative predictive value was 98.85%, and the positive predictive value was 80.82%. CONCLUSION: This study demonstrates that the OAR is highly sensitive in the geriatric population but shows some limitations in terms of specificity and positive predictive value. These results support the effectiveness of using the OAR in evaluating ankle injuries in the geriatric population but also highlight the need for cautious application due to the potential for false-positive outcomes.

Ultrasound guidance versus conventional technique for radial artery puncture in septic shock patients: A pilot study.

BACKGROUND: Arterial puncture, for obtaining an analysis of blood gas, is an interventional procedure often performed in emergency departments and intensive care units. This study compares the ultrasound (US) guided method with the conventional digital palpation method in radial artery puncture (RAP) for blood gas analysis in septic shock patients. METHODS: This is a prospective, single-centre study. Septic shock patients over 18 years of age who needed a RAP sample for blood gas analysis were included. Patients with local infection or trauma at the puncture site, arteriovenous fistula, vascular graft, coagulopathy, a positive Allen test, or did not want to participate were excluded. Patients were randomized into two groups and RAP was obtained with either the US-guided method or the conventional method. The main outcomes were success at first entry, the number of attempts before success, and the time to success. RESULTS: The 50 eligible patients were randomized into two groups. First entry success rate for the US-guided group and the conventional group was 80% and 42%, respectively. The number of attempts before success and time to success was significantly higher in the conventional group. CONCLUSION: The US-guided method has been found to be more successful in terms of first entry success, the number of attempts before success, and the time to success when compared to the conventional method.

Recurrence of COVID-19 Documented with RT-PCR.

We present a case of coronavirus disease 2019 (COVID-19) re-infection where the time interval between two COVID-positive episodes is the longest in the literature. A 40-year male patient was admitted to the Emergency Department with complaints of sore throat, cough and diarrhea; and was re-diagnosed as COVID-19 positive after a virus-free period. He did not have a chronic disease in his anamnesis and used no medication. After COVID-19 infection and a long recovery period, he became COVID-19 positive again. In this case, the time to second COVID-19 infection was 94 days from the first positive PCR test and 86 days from the complete resolution of symptoms. This is one of the longest COVID-19-free period between two episodes of infection in the literature. Key Words: COVID-19, Recurrence, Re-infection, Recovery.

Treatment of Renal Colic by Nerve Blockade with Lidocaine Versus Intravenous Dexketoprofen.

OBJECTIVE: To compare non-steroidal anti-inflammatory drugs (NSAIDs) with spinal nerve blockade of related dermatomes using lidocaine for pain palliation of patients admitted to the Emergency Department (ED) with an episode of renal colic. STUDY DESIGN: Randomised controlled-trial. PLACE AND DURATION OF STUDY: Department of Emergency Medicine, Kartal Dr. Lütfi Kirdar City Hospital, Istanbul, Turkey from May to July 2019. METHODOLOGY: The study included patients admitted to the ED with renal colic randomised into two groups: first group received 2% lidocaine for nerve blockage and the second group received intravenous injection of 50 mg dexketoprofen. All patients were asked to rate the intensity of their pain and on a 0 to 10 point visual analogue scale before and at 5, 15, 30, 45, and 60 minutes after intervention. RESULTS: A total of 126 patients, 56 women and 70 men, were inducted. There were statistically significant differences in the median VAS scores for pain from the 5th minute to the 60th minute in favour of lidocaine. CONCLUSION: Spinal nerve blocks with 2% lidocaine resulted in greater short-term pain relief than intravenous dexketoprofen in ED patients with renal colic. Key Words: Renal colic, NSAID, lidocaine, Nerve blockade.

Clinical Features of the 60 Years and Older Patients Infected with 2019 Novel Coronavirus: Can We Predict Mortality Earlier?

INTRODUCTION: The novel coronavirus (COVID-19), which has affected over 100 countries in a short while, progresses more mortally in elderly patients with comorbidities. In this study, we examined the epidemiological, clinical, and laboratory characteristics of the patients aged 60 and over who had been infected with COVID-19. METHODS: The data of the patients admitted to the hospital within 1 month from May 8, 2020 onwards and hospitalized for COVID-19 pneumonia were obtained from the hospital medical records, and the epidemiological, clinical, and laboratory parameters of the patients during the admission to the emergency department were examined. Patients were divided into 2 groups regarding the criteria of having in-hospital mortality (mortality group) and being discharged with full recovery (survivor group). The factors, which could have an impact on the mortality, were investigated using a univariate and multivariate logistic regression analysis. RESULTS: This retrospective study included 113 patients aged 60 years and older, with a confirmed diagnosis of COVID-19 pneumonia. The mean age of the patients was 70.7 ± 7.9, and 64.6% (n = 73) of them were male. The mortality rate was 19.4% (n = 22). Among the comorbid illnesses, only renal failure was significant in the mortality group (p = 0.04). A CURB-65score ≥3 or pneumonia severity index (PSI) class ≥4 manifested a remarkable discrimination ability to predict 30-day mortality (p < 0.001). When the laboratory parameters were considered, the value of neutrophil to lymphocyte ratio (NLR) was significant in predicting mortality in univariate and multivariate analysis (odds ratio [OR] = 1.11; 95% confidence interval [95% CI], 1.03-1.21; p = 0.006, and OR = 1.51; 95% CI, 1.11-2.39; p = 0.044, respectively). CONCLUSION: In our study, NLR was determined to be an independent marker to predict in-hospital mortality among patients with COVID-19. PSI and CURB-65 revealed a considerably precise prognostic accuracy for the patients with COVID-19 in our study as well. Moreover, thanks to that NLR results in a very short time, it can enable the clinician to predict mortality before the scoring systems are calculated and hasten the management of the patients in the chaotic environment of the emergency room.

Recurrence of COVID-19 Documented with RT-PCR.

We present a case of coronavirus disease 2019 (COVID-19) re-infection where the time interval between two COVID-positive episodes is the longest in the literature. A 40-year male patient was admitted to the Emergency Department with  complaints of sore throat, cough and diarrhea; and was re-diagnosed as COVID-19 positive after a virus-free period. He did not have a chronic disease in his anamnesis and used no medication. After COVID-19 infection and a long recovery period, he became COVID-19 positive again. In this case, the time to second COVID-19 infection was 94 days from the first positive PCR test and 86 days from the complete resolution of symptoms. This is one of the longest COVID-19-free period between two episodes of infection in the literature. Key Words: COVID-19, Recurrence, Re-infection, Recovery.

Investigation of QT Prolongation with Hydroxychloroquine and Azithromycin for the Treatment of COVID-19.

OBJECTIVE: To assess and identify the risk of prolonged QT about hydroxychloroquine (HQ) and azithromycin (AZ) used in the treatment of patients with COVID-19. STUDY DESIGN: Cohort study. PLACE AND DURATION OF STUDY: Kartal Dr. Lütfi Kirdar City Hospital, Istanbul, Turkey, from March to May 2020. METHODOLOGY: One hundred and forty-four patients with the diagnosis of COVID-19, confirmed by Rt-PCR (reverse transcription-polymerase chain reaction), were restrospectively reviewed. Patients who were hospitalised, received HQ or HQ plus AZ treatment, had a baseline electrocardiogram (ECG), and had at least one ECG after treatment were included in the study. Patients with missing data were excluded. RESULTS: Fifty-one (35.4%) patients were given hydroxychloroquine monoterapy (HQ), 93 (64.6%) were given hydroxychloroquine plus azithromycin (HA), and 70 (48.6%) were women. Pre-treatment mean QTc measurements were calculated as 410.61 ± 29.44 milliseconds (ms) for HQ group and 412.02 ± 25.37 ms for HA group, while the mean values of post-treatment QTc measurements were calculated as 432.31 ± 33.97 ms for HQ group and 432.03 ± 27.0 ms for the HA group. Post-treatment QTc measurements of both HA group and HQ group were prolonged compared to pre-treatment measurements. Ventricular arrhythmia was not observed in any patient. CONCLUSION: For COVID-19, no globally accepted definite treatment has yet been found. Both of hydroxychloroquine monotherapy and hydroxychloroquine plus azithromycin treatment regimens cause QTc measurement to increase at a statistically significant level. We concluded that this increase in QTc did not cause ventricular arrhythmia. Key Words: COVID-19, QTc interval, Hydroxychloroquine, Azithromycin.

Role of circulating microRNAs in acute appendicitis.

BACKGROUND: Acute appendicitis (AA) is a momentous, emergency, surgical pathology that has still been investigated for both etiopathogenetic unknowns and challenges in diagnosis. Presently, there is little information about the role of microRNAs (miRNAs), which have basic biological functions in the cell, can be a marker, and are associated with various pathologies, in patients with AA. The aim of this study was to investigate the expressions of some miRNAs in AA. METHODS: Overall, 41 miRNAs were screened in 48 individuals comprising 24 patients with AA and 24 healthy controls at Erciyes University Genome and Stem Cell Center (GENKOK). The obtained data were analyzed using appropriate statistical methods. RESULTS: miR-29c-3p was found to be increased 2-fold during the first 4-6 h in AA, and this increase was revealed to be statistically significant compared with healthy individuals. Similarly, expressions of let-7b-5p, let-7i-5p, miR-30a-5p, miR-29b-3p, and miR-23a-3p also increased approximately 2-fold in AA, although not statistically significant. No significant differences were found in the screening of the remaining 35 miRNAs in patients with AA. CONCLUSION: Although there is little information about the relationship between AA and miRNAs currently, miR-29c-3p was reported to increase in the acute period of AA in this study. With the current results, it can be argued that miR-29c-3p bears the potential to be a marker in patients with AA. The present study may also be a basic research for more extensive and necessary miRNAs screening in this field.
