Comparison of analgesic efficacy of ibuprofen and dexketoprofen in pain management of long bone fractures: a prospective, randomized, double-blind study.

INTRODUCTION: Long bone fractures (LBF) often cause severe pain, impacting patients' quality of life. This prospective, randomized, double-blind study aimed to compare the analgesic efficacy of dexketoprofen (Dex) and ibuprofen (Ibu) in LBF patients in the emergency department. METHODS: Conducted between August 10, 2023, and January 17, 2024, the study included 100 eligible patients randomized into Dex and Ibu groups. Visual analog scale (VAS) scores were measured at baseline and at 30, 60, and 120 min. DeltaVAS (ΔVAS) values and ΔVAS percentages (ΔVAS%) were calculated. Primary endpoints were ΔVAS scores (ΔVAS 30-60-120) and ΔVAS% for comparative analysis. RESULTS: Statistical analysis showed no significant difference in ΔVAS30 (p = 0.359). However, ΔVAS60 exhibited a significant difference (p = 0.027), as did ΔVAS120 (p = < 0.001). ΔVAS%30 showed no significance (p = 0.224), but ΔVAS%60 and ΔVAS%120 were clinically and statistically significant (p = 0.017 and p = < 0.001, respectively). CONCLUSION: Ibuprofen 800 mg demonstrated superior analgesic efficacy at 60 and 120 min compared to Dex in long bone fractures. These findings suggest ibuprofen's potential as an effective pain management option in emergency departments.

Effect of coolant spray on rib fracture pain of geriatric blunt thoracic trauma patients: a randomized controlled trial.

OBJECTIVE: This study aimed to evaluate the effectiveness of cryotherapy in elderly patients with rib fractures due to blunt thoracic trauma. METHODS: In this prospective randomized controlled study, geriatric patients were assigned to groups to receive either coolant spray (n=51) or placebo spray (n=50). The visual analog scale scores of all patients were recorded before starting spray application (V0), as well as at 10th (V1), 20th (V2), 30th (V3), 60th (V4), 120th (V5), and 360th (V6) minute. The mean decreases in the visual analog scale scores were calculated. RESULTS: The differences between V0 and V1, V0 and V2, V0 and V3, and V0 and V4 mean visual analog scale scores measured in the coolant spray group were found to be significantly higher (p<0.001). In V1, V2, V3, and V4 measurements, the incidence of "clinical effectiveness" in the coolant spray group was significantly higher than in the placebo group (p=0.001). CONCLUSIONS: Coolant spray therapy can be used as a component of multimodal therapy to provide adequate analgesia due to rib fractures in geriatric patients.

Injuries in Recreational Footballers and the Severe Consequences of Player-to-Player Contact: A Prospective Observational Study.

Introduction Football is the most popular sport in the world with its wide audience and important economic effects. This game is mainly played by professional football players, it is also an activity that is frequently played by non-professionals. Although members of the public mostly engage in this sport as a hobby and to develop a healthy lifestyle, vital injuries, such as head and thorax trauma can also occur during these recreational activities. In this study, our aim was to identify these severe traumas, investigate their causes and mechanisms, and make suggestions to reduce trauma among recreational football players. Methods This prospectively designed study included players aged over 14 years who presented to the emergency department with an injury incurred during a recreational football match activity. The demographic characteristics of the patients, warm-up status, match conditions, field conditions, and injury mechanisms, as well as post-injury outcomes, were recorded and analyzed with appropriate statistical methods. Results There were 167 patients included in the study and 140 of these patients were eligible for the study. We identified 45 cases with poor outcomes such as pneumocephalus, rib fractures, pneumothorax, Achilles tendon rupture, and bone fractures. (32.1%). Factors that could have an effect on poor outcomes were determined as a pre-match warm-up, pre-match sleep duration, and suitability of equipment. Player-to-player contact was determined as a mechanism of head and thorax trauma. Conclusions It may be beneficial to inform recreational football players about how player-to-player contact can cause head and thoracic trauma and establish a database of sports injuries in hospitals.

Intravenous ibuprofen versus sodium valproate in acute migraine attacks in the emergency department: A randomized clinical trial.

OBJECTIVE: Sodium valproate and ibuprofen are drugs with known efficacy in the treatment of headache associated with acute migraine attacks. In this study, our aim was to compare the efficacy of these two drugs in the treatment of acute migraine attacks when administered as a single intravenous (IV) dose in the emergency department. MATERIALS AND METHOD: This study was designed as a prospective, randomized controlled, double-blinded study and included patients aged 18 to 65 years who presented to the emergency department with acute headache and met the criteria of 'migraine without aura' according to the International Classification of Headache Disorders. The patients were randomized into two groups and given a single dose of 800 mg sodium valproate or 800 mg ibuprofen in 150 mL of normal saline by IV infusion over five minutes. Changes in pain levels were assessed using the Numerical Rating Scale (NRS) for pain over a two-hour period. RESULTS: Ninety-nine patients (49 patients in the sodium valproate group and 50 in the ibuprofen group) completed the trial, and their data were included in the statistical analysis. The mean decrease in the post-treatment delta NRS values was statistically significantly higher in the sodium valproate group than in the ibuprofen group. The mean differences were 1.69 [confidence interval (CI): 1.02-2.37, p<0.001], the mean difference between N0 and N2 was 3.61 (CI: 2.96-4.26, p < 0.001), the mean difference between N0 and N3 was 4.11 (CI: 3.54-4.67, p < 0.001), and the mean difference between N0 and N4 was 3.92 (CI: 3.67-4.46, p < 0.001). The number of patients who achieved the primary endpoint of pain relief was significantly higher in the sodium valproate group than in the ibuprofen group (p < 0.001). According to the Kaplan-Meier analysis showing the rates of reaching the targeted endpoint, there was a significant difference in the efficacy of the two-treatment group (χ2 = 79.98, CI: 80.35-99.65; p = 0.000).

Is endogenous carboxyhaemoglobin level a useful biomarker of clinical course and prognosis in COVID-19 patients?

OBJECTIVE: SARS-CoV-2 has caused nearly 4 million confirmed cases of COVID-19 worldwide in the approximately 4 months since it emerged in Wuhan, China in December 2019. Comorbidities increase morbidity and mortality in COVID-19, and many laboratory parameters have been associated with mortality. The aim of the present study was to identify the relationship between endogenous carboxyhaemoglobin (COHb) level and the clinical course and prognosis of COVID-19. METHODS: The study included 48 non-smokers or ex-smokers aged 18 years or older who presented to the emergency department, were diagnosed with COVID-19 by real-time PCR analysis of nasopharyngeal swab sample and were treated in the pulmonary diseases ward of the Atatürk University hospital after 24 March 2020 and 15 April 2020. The patients' laboratory parameters and demographic data were analysed retrospectively. RESULTS: Prothrombin time and C-reactive protein (CRP), troponin-I, and D-dimer levels decreased in COVID-19 patients during follow-up (P = .024, P = .001, P = .001, P = .001), while PaO2 /FiO2 ratio and COHb increased (P = .002, P = .001). COHb level at admission was significantly lower in patients who developed macrophage activation syndrome (MAS), acute respiratory distress syndrome (ARDS), and those who died compared with the other patients (P = .002, P = .001). COHb level on day 5 of treatment was significantly higher in patients with ARDS and patients who died (P = .001, P = .001). Significant correlations were detected between COHb level and CRP (r=-0.425, P = .001), ferritin (r = -.395, P = .001) and PaO2 /FiO2 ratio (r = .431, P = .001). CONCLUSIONS: COHb level may be an easily accessible biomarker that guides early follow-up and treatment planning to avoid ARDS, MAS and mortality in COVID-19.

Intradermal mesotherapy versus intravenous dexketoprofen for the treatment of migraine headache without aura: a randomized controlled trial.

BACKGROUND: Migraine is a prevalent disabling primary headache disorder that is classified into two major types: migraine without aura and migraine with aura. New therapeutic methods to reduce migraine headaches in the emergency department (ED) include intradermal mesotherapy. OBJECTIVE: Compare the efficacy of intradermal mesotherapy versus a systemic therapy in pain control in patients with headache related to migraine without aura. DESIGN: Prospective parallel-group randomized controlled trial. SETTING: University hospital in Turkey. PATIENTS AND METHODS: Patients 18 years of age and older who were admitted to the ED over a 15-month period with headache related to migraine without aura were eligible for inclusion if they had a VAS score of 4 or above. Patients were randomly allocated to one session of mesotherapy or intravenous dexketoprofen. Changes in pain intensity were measured by the score on a visual analog scale (VAS) at 30, 60, and 120 minutes and 24 hours after treatment. Efficacy was also assessed by the need for use of an analgesic drug within 24 hours, by readmission with the same complaint to the ED within 72 hours, and by adverse effect rates. MAIN OUTCOME MEASURE: Pain intensity on the VAS scale. SAMPLE SIZE: 148 patients (154 enrolled and treated; 1 patient in the mesotherapy and 5 patients in the systemic therapy group lost to follow up). RESULTS: Pain intensity on the VAS scale decreased from a median score of 8 to 4 in the mesotherapy group and from 8 to 5 in the systemic therapy group. These differences were statistically significant from baseline for all time intervals (P=.001 to 30 minutes, P=.004 to 60 minutes, P=.005 to 120 minutes, and P=.002 to 24 hours). The need to use analgesics and the rate of readmission to the ED were higher in the systemic therapy group (P=.013 and P=.030, respectively). Adverse effect rates were minimal and similar in the study groups during the one-week follow-up period. CONCLUSIONS: Mesotherapy is more efficacious than intravenous dexketoprofen in the management of acute attack of migraine without aura in the ED. LIMITATIONS: Unblinded. Valid for assessing short-term pain relief, but not sufficient to predict long-term efficacy. Not generalizable because single center and small sample size. CONFLICT OF INTEREST: None. REGISTRATION: ClinicalTrials.gov (NCT04519346).

Effectiveness of Modified HEART Score in Predicting Major Adverse Cardiac Events.

OBJECTIVE: The most important problem for emergency physicians in patients presenting with chest pain is deciding whether to discharge the patient or not. Therefore, many scoring systems have been developed to help with this decision making process. We aim to achieve a modified HEART value by combining the VAS value with the HEART score. MATERIALS AND METHODS: Data were collected on age, sex, duration of the symptoms, pain severity using a 10-point visual analog scale (VAS), and the presence of a major adverse cardiac event (MACE). The HEART score was calculated and modified (mHEART) by adding 1 point to the total HEART score for a VAS score of ≥7. RESULTS: During the study period, 4781 patients were admitted, and 293 participants were analyzed. Of the patients, 34(11.6%) experienced MACE within a month after the encounter. The mean VAS scores were 5.65±1.44. However, 77(26.3%) patients had VAS scores ≥7. Taking 3 as the threshold, 42(14.3%) patients had HEART scores of 4 and above, where 47(16.0%) had mHEART scores ≥4. The mHEART scoring demonstrated better test indicators than the HEART score. According to the HEART score, 6(2.3%) of the 251 patients predicted as negative would develop MACE, but this number decreased to 1(0.4%) in 246 using the mHEART score. CONCLUSION: Although the HEART score performs reasonably well in discriminating patients who are MACE negative, it is possible to further improve the score by adding the VAS item. After validation by other studies, we would suggest modifying the HEART score by including the VAS item.

Comparison of ibuprofen and piroxicam gel in the treatment of trauma pain: A randomized double-blind trial of geriatric population.

OBJECTIVE: This study aimed to compare the analgesic efficacy of topical ibuprofen and topical piroxicam for acute musculoskeletal injuries. METHODS: In this prospective, randomized, controlled, double-blinded study, geriatric patients were assigned to groups to receive either topical ibuprofen (n = 70) or topical piroxicam (n = 69). The first dose of gel was applied in the emergency department and the remaining doses were self-administered at home by the patients thrice daily for 72 h. For each patient, the initial baseline visual analog scale (VAS) score (V 0) was compared with the VAS scores at the 60 min (V1), 120 min (V2), 24 h (V3) and 72 h (V4) time points. The decreases in VAS scores, clinical effectiveness of the treatments, and incidence of adverse events were evaluated. RESULTS: In the topical ibuprofen group, the VAS scores were significantly lower at each measurement time point compared to baseline (p < .001). The results were as follows: V0 -V: 1.08, 95% CI: 0.56-1.61; V0 -V2: 1.09, 95% CI: 0.49-1.69; V0 -V3: 1.44, 95% CI: 0.81-2.07; V0 -V4: 1.59, 95% CI: 0.91-2.26. The mean percentage decrease in the VAS scores in the topical ibuprofen group was significantly higher than that in the topical piroxicam group (p < .001). The clinical effect of treatment was found to be significantly higher for the ibuprofen gel group (p < .001). There was no substantial difference in treatment-related adverse events between the groups (p > .05). CONCLUSION: Ibuprofen gel, which is a safe treatment option for geriatric patients, is more clinically effective than piroxicam gel. Response to Reviewers.

Comparison of topical capsaicin and topical piroxicam in the treatment of acute trauma-induced pain: A randomized double-blind trial.

BACKGROUND: This study aimed to compare the analgesic efficacy of topical capsaicin and topical piroxicam in acute musculoskeletal injuries. METHODS: This is a prospective, randomized, controlled, double-blinded study. The data for the 67 patients in the piroxicam group and the 69 in the capsaicin group were examined. The initial visual analog scale (VAS) scores were compared with the 60th and 120th minute as well as the 24th and 72nd hour values. Differences between the VAS scores, clinical effectiveness of the treatment and side effects were evaluated. RESULTS: In the capsaicin group, the mean difference in the delta VAS scores was significantly higher at each measurement time. The mean of the percentage of reduction in the VAS scores of the topical capsaicin group was significantly higher than that in the topical piroxicam group. The highest difference in terms of both outcomes was determined at the 72nd hour VAS change. Mean differences were 1.53 (95% CI: 0.85-2.221) and 19.7 (95% CI: 12.4-27.2) respectively (p < 0.001). In the capsaicin group, the clinical effect of the treatment was found significantly higher (p < 0.01). The difference between the clinical effectiveness of the groups regarding the treatment outcomes was also statistically significant (p < 0.001). There was no significant difference between the patient groups regarding the presence of side effects. CONCLUSION: Topical capsaicin can be used as an alternative to topical piroxicam initially and at follow-up in patients presenting to the emergency department with acute pain as there were no observable differences in side-effects between the two groups.

Intradermal injection for hiccup therapy in the Emergency Department.

Hiccup is a condition caused by involuntary contraction of inspiratory muscles, especially the diaphragm. Although it is generally considered as a physiological. response, if hiccup persists for a long time, it can lead to many undesirable conditions such as depression, weight loss, insomnia, and fatigue. A 35-year-old male patient was admitted to our emergency department with hiccup lasting for 15 h. He had a history of several hiccup attacks. Classical non-pharmacological and pharmacological therapies were used to treat the condition without any response. As an alternative method, an intradermal injection was applied. A mixture of thiocolchicoside and lidocaine was administered intradermally to a depth of 1-3 mm at the epigastric region and adjacent to the sternocleidomastoid muscle. The patient's hiccup ended after the intradermal injection procedure. During 48 h of follow-up the hiccup attack did not develop again. No complications related to the process were detected. This is the first case in the literature demonstrating the use of intradermal injection to terminate hiccups. The intradermal injection approach can be administered in cases of hiccups that do not respond to medical treatment.

Comparison of effectiveness coolant spray and placebo in patients with acute ankle trauma prospective randomized controlled trial.

INTRODUCTION: Coolant spray application in musculoskeletal injuries is an effective and harmless method to treat pain and reduce functional limitation. This study assessed the clinical value of coolant spray application on patient comfort before and during the radiographic imaging process along with its early analgesic and anti-edema effects. METHODS: A total of 155 patients, admitted to the emergency department between April 1, 2019, and June 31, 2019, were included in this study. The patients were randomly assigned to either a coolant spray or a saline spray (placebo) group. To the coolant spray group patients, Cryos ®Spray (Phyto Performance, Italy) was applied. To the placebo group patients, a normal saline solution in a bottle covered with white opaque paper and refrigerated at 4 °C was sprayed. Radiographic images of the patients were scored for appropriateness of the standard imaging characteristics. RESULTS: The mean scores were 8.13 ± 1.8 and 6.58 ± 2.2 for the coolant spray and normal saline spray groups, respectively; the differences were statistically significant between the two groups (mean difference: -1.56, 95% CI:-2.20 to -0.92; p = .000). Patients with fractures on their radiographs and treated with coolant spray received higher scores than similar patients treated with normal saline spray (mean difference:-1.92, 95% CI:-3.28 to -0.55; p = .009). The proportion of patients requesting analgesic treatment before discharge was statistically lower in the coolant spray group compared to the normal saline group (p = .025). CONCLUSIONS: The radiographic images taken after coolant spray intervention in patients with acute ankle trauma were more successful in showing the target structures.

Comparison of two scores of short term serious outcome in COPD patients.

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) related visits to the emergency department have increased substantially during the past decade. An important challenge facing emergency physicians when treating COPD patients is deciding on disposition. The aim of this study was to evaluate Integrated Pulmonary Index scoring to guide the disposition decisions of emergency physicians by comparing its compatibility with Ottawa COPD Risk Score. METHODS: This is a prospective methodological study, in which we compared the accuracies of the Integrated Pulmonary Index and Ottawa COPD Risk Score in predicting of the short-term serious outcomes in patients admitted to the emergency department with COPD exacerbation. Patients who admitted to our emergency department between 01.01.2019-31.03.2019 were evaluated. THE RESULTS: Among the 208 patients, there were 154 (74.0%) short-term serious outcomes. The AUCs were 0.915 and 0.943 for Integrated Pulmonary Index and Ottawa COPD Risk Score, respectively. The difference between AUCs for two scores was not statistically significant. The best cut-off point for Integrated Pulmonary Index and Ottawa COPD Risk Score were ≤3 and >4, respectively. For these best cut-off points, the sensitivity and specificity of Integrated Pulmonary Index were 92.9 and 87.1, respectively. The sensitivity and specificity of Ottawa COPD Risk Score were 99.3 and 85.2, respectively. Besides, the accuracy of Integrated Pulmonary Index was 91.3, and the accuracy of Ottawa COPD Risk Score was 95.7. CONCLUSIONS: Integrated Pulmonary Index was a potential candidate for evaluating respiratory status and prediction of short-term severe events in patients with acute COPD exacerbation in emergency departments.

Comparison of intradermal mesotherapy with systemic therapy in the treatment of low back pain: A prospective randomized study.

INTRODUCTION: Musculoskeletal pain such as low back pain (LBP) are routinely encountered in the ED and contribute to ED overcrowding. The aim of our study was to compare the efficiency of mesotherapy with systemic therapy in pain control in patients with lumbar disk herniation. METHODS: We conducted this prospective parallel randomized controlled trial with the patients admitted to the emergency department with low back pain related to herniated lumbar disk. Mesotherapy was performed to one group, while intravenous dexketoprofen was administered to the control group. Changes in pain intensity at 15th minute, 30th minute, 60th minute and 24th hours after treatment using Visual Analogue Scale (VAS), need to use analgesic drug within 24 h after treatment, and adverse effect of the treatment methods were compared between groups. RESULTS: The decreases in pain intensity were statistically significantly higher in mesotherapy group for all time intervals. The need to use analgesics was statistically significantly three fold higher in the systemic therapy group. There was no statistically significant difference in having any adverse effect between study groups during one-week follow-up period. CONCLUSIONS: Changes in medical practices, from the systemic administration of NSAIDs to the minimally invasive techniques such as mesotherapy with potent efficacy and minimal side effects, may enhance the ability of EDs to meet the waiting time targets and improve patient's satisfaction.

Assessment of the Accuracy of Cardiopulmonary Resuscitation Videos in English on YouTube according to the 2015 AHA Resuscitation Guidelines.

Over the last decade, YouTube has become one of the largest online resources for medical information. However, uploaded videos are published without any peer review or quality control, so incorrect and incomplete information can be easily disseminated via the virtual platform and can be perceived as correct. The YouTube website was searched for videos in English uploaded between 15 October 2015 and 21 October 2016 using the following keywords: "CPR," "cardiopulmonary resuscitation," and "basic life support." This study had a cross-sectional analytical design. In the first evaluation, the accuracy of the videos was checked according to the information contained in the basic cardiac life support algorithm. In the second evaluation, we assessed whether advanced-level, innovative medical information was included in these videos; when included, the accuracy of such information was checked. Of 774 videos evaluated, 92 videos were included in the study after application of the exclusion criteria. The videos were scored on a scale ranging from 0 to 20 points. The mean total score, based on all criteria, was 4.79 ± 2.88. The highest mean total score was achieved by videos uploaded by official medical organizations (6.43 ± 3.57), followed by those uploaded by health professionals and organizations (4.25 ± 2.49), and those uploaded by unidentified sources. YouTube videos are insufficient in providing information about the basic life support algorithm and advanced-level information according to the 2015 AHA resuscitation guidelines for health professionals. The educational material published by health institutions that are constantly working in the area is a more reliable source of information on subjects that directly affect human life, such as cardiopulmonary resuscitation.

Comparison of intravenous NSAIDs and trigger point injection for low back pain in ED: A prospective randomized study.

INTRODUCTION: Low back pain (LBP) is a common complaint originating from muscles Myofascial pain syndrome (MPS) is mainly associated with trigger points (TrP) in the muscle tissue. We compared the intravenously administered non-steroidal anti-inflammatory drug (NSAID) and trigger point injection (TPI) in the treatment of LBP patients admitted to the emergency department due to pain caused by TrPs. MATERIAL AND METHOD: After randomization, NSAID was administered intravenously in group 1 and TPIs were performed as specified by Travell and Simons in group 2. The TrPs were identified with the anamnesis and physical examination Demographic characteristics and vital signs of the patients were recorded. Pain scores were measured with the Visual Analogue Scale (VAS) at admission; and in minutes 5, 10, 15, 30, and 60. RESULTS: There were 32 patients in group 1 and 22 patients in group 2. The demographics, vital signs, and pain scores at admission were not statistically significantly different between the groups. The pain scores decreased significantly in the TPI group. During the 60 min' follow-up period, the mean VAS pain score decreased by 0.41 ±â€¯1.30 in the TPI group and by 2.59 ±â€¯2.37 in the NSAID group (p < 0.001). Respond the treatment was significantly higher group TPI than Group NSAID (21/22 vs 20/32 respectively, p = 0.008). CONCLUSION: In this small randomized study with several methodological limitations, TPI was superior to the intravenous NSAIDs in the treatment of acute LBP due to TrPs. TPI can be used in the emergency departments for the acute treatment of LBP in selected patients.

Is this a simple drug eruption to be discharged?

'Erythema Multiforme associated with Phenytoin And Cranial radiation Therapy' (EMPACT) is a very rare clinic situation and classified in EM-like drug reactions. It can be easily misdiagnosed as acute urticaria or drug eruption in ED. Initial symptoms may resemble a simple skin problem, but diagnosing and early hospitalization of the patients can be lifesaving. Here, we present a man with renal cell cancer and brain metastases who admitted to ED due to fever and generalized rash. His skin lesions beginning from his head and spreading through the torso appeared four days after the end of radiotherapy (11 days after the initial dose of both radiation and oral phenytoin). Inspection showed erythematous lesions on the scalp, neck, torso and arms. These lesions had desquomative character on the scalp. Erythematous maculopapular lesions with the tendency of fusion were also visible on the chest, abdomen, back, on the flexor areas of the arm, forearm and femoral region. Laboratory studies showed normal complete blood counts, high creatinine kinase, creatinine kinase-MB, gamma-glutamyl transpeptidase, aspartate aminotransferase, lactate dehydrogenase, albumin and total protein. After discontinuation of phenytoin and giving H1, H2 receptor blockers and steroid intravenously, he was discharged two weeks later with full recovery.

Spontaneous reduction of ileoileal adult intussusception after blunt abdominal injury.

This is the first case report of an adult who had spontaneous reduction of ileoileal intussusception occurred after punching to the abdomen. A 40-year-old man was brought to our emergency department by ground ambulance due to pounding and punching a few hours ago. Physical examination showed multiple dermabrasions on his face, abdomen, and lower extremities. All other examinations were unremarkable except that of mild abdominal pain. Laboratory results gave no clues. On abdominal x-ray, paucity of intestinal gas, pseudomass and surrounding gas appearances were visible. No nausea or vomiting occurred during observation. His abdominal pain resolved gradually. On the 24th hour after admission, control computed tomography showed that the findings of intussusception disappeared. He was discharged after 1 day of observation. Outpatient follow-up did not show any abnormality. We suggest that, in patients with mild to moderate trauma, even if the patient has mild abdominal pain, physicians should rule out invagination. Computed tomography is the suggested imaging modality. These patients should be kept in close follow-up. If symptoms resolve and intussusception findings disappear in computed tomography, no further treatment is required.
