Efficacy and Safety Analysis of Botox Application and Iatrogenic Botulism: Panacea or Peril?

Clostridium botulinum toxin-A (BoNT-A) creates temporary paralysis in the muscles by acting on the muscle-nerve junction. It is injected into the mimic muscles when a decrease in the movements of the mimic muscles is desired. Despite many favorable applications, the use of BoNT-A is not without drawbacks. Although there is no expected serious side effect on health in BoNT-A treatments, various problems can be encountered in patients treated for aesthetic purposes. Botulism is a rare but potentially life-threatening syndrome, which is caused by the toxin produced by the bacterium Clostridium botulinum, which acts on the nervous system, vegetative forms of C. botulinum can only survive in anaerobic conditions, while spore forms are common in nature and can withstand harsh conditions. Botulism can stem from bacterial spores which release toxin in the body; in the form of enteric botulism, and wound botulism. The cases that develop 'iatrogenic botulism' after such procedures are usually those receiving high-dose toxin for therapeutic purposes. The treatment of botulism mainly consists of anti-toxin therapy and, if necessary, intensive care to prevent organ failures, including respiratory support. This article aims to cover all these issues related to botulism and other adverse outcomes related to BoNT-A injection in light of the most recent literature.

Procedural (Conscious) Sedation and Analgesia in Emergency Setting: How to Choose Agents?

Pain has long been defined as an unpleasant sensory and emotional experience originating from any region of the body in the presence or absence of tissue injury. Physicians involved in acute medicine commonly undertake a variety of invasive and painful procedures that prompt procedural sedation and analgesia (PSA), which is a condition sparing the protective airway reflexes while depressing the patient's awareness of external stimuli. This state is achieved following obtaining the patient's informed consent, necessary point-ofcare monitoring, and complete recording of the procedures. The most commonly employed combination for PSA mostly comprises short-acting benzodiazepine (midazolam) and a potent opioid, such as fentanyl. The biggest advantage of opioids is that despite all the powerful effects, upper airway reflexes are preserved and often do not require intervention. Choices of analgesic and sedative agents should be strictly individualized and determined for the specific condition. The objective of this review article was to underline the characteristics, effectiveness, adverse effects, and pitfalls of the relevant drugs employed in adults to facilitate PSA in emergency procedures.

Can we recognize severe community-acquired pneumonia without pneumonia severity index? Use of modified qSOFA with procalcitonin.

Objective: The aim of this study is to analyze the diagnostic value of Quick Sequential Organ Failure Assessment (qSOFA), modified qSOFA, National Early Warning Score (NEWS) and NEWS + Lactate (NEWS + L) scores in the detection of severe community-acquired pneumonia (CAP). Methods: This research is a retrospective cohort study. Patients admitted to the Emergency Department (ED) with the diagnosis of CAP were divided into severe and mild pneumonia regarding their Pneumonia Severity Index (PSI) scores. The accuracies of lactate, procalcitonin (PCT) values, NEWS and qSOFA scores, as well as score combinations (NEWS + L and qSOFA + PCT) in predicting patients with severe CAP were analyzed. Results: Median qSOFA value in the severe CAP group (0 [IQR 0-1]) was found to be higher than median qSOFA value (0 [IQR 0-0]) in the mild CAP group (p < 0.001). The rate of qSOFA positivity (qSOFA ≥ 2) was significantly higher in the severe CAP group (17.1%, n = 21) compared to the mild CAP group (1.3%, n = 1) (p < 0.001). Median qSOFA + PCT for the severe CAP group (2 [IQR 1-2]) was higher than the mild CAP group (1 [IQR 0-1]) (p < 0.001). Mean NEWS score for severe CAP (4.95 ± 3.09) was found to be 1.69 (95% CI 0.92-2.46) higher than mean NEWS score of the mild CAP group (3.26 ± 2.39) (p < 0.001). The severe CAP NEWS + L score (6.97 ± 3.71) was higher than the mild CAP NEWS + L score (4.94 ± 2.48) (p < 0.001). Blood lactate level was not significant in the evaluation of severe CAP (p = 0.221). PCT (AUROC = 0.685 [95% CI 0.610-0.760]; p = 0.038), NEWS score (AUROC = 0.658 95% CI [0.582-0.733]; p < 0.001), qSOFA (AUROC = 0.686) were calculated to have adequate accuracy for the detection of severe CAP. [95% CI 0.613-0.759]; p = 0.037), NEWS + L score (AUROC = 0.665 [95% CI 0.589-0.740]; p = 0.038). The qSOFA + PCT score (AUROC = 0.758 [95% 0.691-0.825]; p = 0.034) was also found to be a highly accurate predictor of severe CAP. Conclusion: In this study, we found a combination of qSOFA and PCT to be the most reliable method of detecting severe CAP.

Diagnostic and Prognostic Roles of Procalcitonin and Other Tools in Community-Acquired Pneumonia: A Narrative Review.

Community-acquired pneumonia (CAP) is among the most common causes of death and one of the leading healthcare concerns worldwide. It can evolve into sepsis and septic shock, which have a high mortality rate, especially in critical patients and comorbidities. The definitions of sepsis were revised in the last decade as "life-threatening organ dysfunction caused by a dysregulated host response to infection". Procalcitonin (PCT), C-reactive protein (CRP), and complete blood count, including white blood cells, are among the most commonly analyzed sepsis-specific biomarkers also used in pneumonia in a broad range of studies. It appears to be a reliable diagnostic tool to expedite care of these patients with severe infections in the acute setting. PCT was found to be superior to most other acute phase reactants and indicators, including CRP as a predictor of pneumonia, bacteremia, sepsis, and poor outcome, although conflicting results exist. In addition, PCT use is beneficial to judge timing for the cessation of antibiotic treatment in most severe infectious states. The clinicians should be aware of strengths and weaknesses of known and potential biomarkers in expedient recognition and management of severe infections. This manuscript is intended to present an overview of the definitions, complications, and outcomes of CAP and sepsis in adults, with special regard to PCT and other important markers.

Local Anesthetics, Clinical Uses, and Toxicity: Recognition and Management.

Local anesthetic (LA) compounds decrease the permeability of the ion channels to sodium, which in turn, diminishes the rate of depolarization. These agents (a.k.a. -caines) are also used to depress mucosal sensations, e.g., gag reflex in the form of topical anesthetics. Overdose of LA can lead to local anesthetic systemic toxicity (LAST), which is the precursor of potentially lethal consequences on clinical grounds. There is a wide array of possible presentations of LAST, from mild findings, such as temporary hypertensive events, to serious conditions, including refractory cardiac dysfunction, dysrhythmias and prearrest situations. Lidocaine, prilocaine, mepivacaine, ropivacaine, and bupivacaine are among the most commonly used members of the family. The agents' dosages should be adjusted in children, elderly and fragile individuals and those with organ failures, as the metabolism of the compounds will be impaired. The ideal body weight, along with hepatic and renal functional reserves, will have an impact on elimination kinetics. Systemic absorption is an untoward consequence of LA administration which deserves every means of prevention. Intravenous lipid emulsion is an important life-saving treatment in severe, life-threatening cases. This narrative review article is designed to cover the clinical uses of LA in children, recognition, and management of untoward effects of the agents, with special emphasis on the LAST.

Direct (New) Oral Anticoagulants (DOACs): Drawbacks, Bleeding and Reversal.

BACKGROUND AND OBJECTIVE: Direct (new) Oral Anticoagulants (DOACs) have emerged as a contemporary and promising option in the treatment of thromboses and VTE, while protecting the coagulation cascade against untoward bleeding events. They are used in the management and prophylaxis of Venous Thromboembolism (VTE) and other thrombotic diseases. The most prominent complication of these agents is bleeding. These agents have similar or lower rates of major intracranial hemorrhages, while they had a higher risk of major gastrointestinal bleeding when compared to warfarin. This manuscript is aimed to revise and update the literature findings to outline the side effects of DOACs in various clinical scenarios. METHODS: A narrative review of currently published studies was performed. Online database searches were performed for clinical trials published before July 2021, on the efficacy and adverse effects attributed to the anticoagulant treatment, especially DOACs. A literature search via electronic databases was carried out, beginning with the usage of the agents in the Western Languages papers. The search terms initially included direct (new) oral anticoagulants, dabigatran, rivaroxaban, apixaban, edoxaban, idarucizumab, andexanet, prothrombin complex concentrates, and fresh frozen plasma. Papers were examined for methodological soundness before being included. RESULTS: Severe bleeding episodes require aggressive interventions for successful management. Therefore, bleeding should be evaluated in special regard to the location and rate of hemorrhage, and total volume of blood loss. Patient's age, weight and organ dysfunctions (e.g., kidney/liver failure or chronic respiratory diseases) directly affect the clinical course of overdose. CONCLUSION: Management recommendations for hemorrhage associated with DOAC use vary, depending on the class of the culprit agent (direct thrombin inhibitor vs. FXa inhibitor), the clinical status of the patient (mild/ moderate vs. severe/life-threatening), and capabilities of the institution. Specific reversal agents (i.e., idarucizumab and andexanet alfa) can be used if available, while prothrombin complex concentrates, fresh frozen plasma and/ or tranexamic acid can also be employed as nonspecific replacement agents in the management of DOAC-related bleeding diathesis.

An Update of the Efficacy and Comparative Characteristics of Direct (New) Oral Anticoagulants (DOACs).

Direct (New-generation) Oral Anticoagulants (DOACs) have emerged as effective agents which are used in place of vitamin-K antagonists in treatment and prophylaxis of Venous Thromboembolism (VTE), atrial fibrillation and other thrombotic diseases. Among them, the FIIa- direct thrombin inhibitor dabigatran and FXa inhibitors (rivaroxaban, apixaban, edoxaban) are the most broadly used. Anticoagulant dosing may differ under special considerations. The patients' physiological reserves, organ functional status and failures should be taken into account in clinical decision-making processes. The advantages and drawbacks of each specific agent should be weighed with special regard to metabolism, pharmacokinetics and pharmacodynamics, along with the efficiency of the agents in different indications. This article aims to review the most recent literature to highlight the usage and efficacy of the agents in different clinical conditions.

Variants in TNF and NOS3 (eNOS) genes associated with sepsis in adult patients.

BACKGROUND: Sepsis is a life-threatening condition caused by a dysregulated host response to infections and is a leading cause of death in hospitalized patients. The present study aimed to elucidate the possible association between sepsis and the tumor necrosis factor (TNF) gene -308G/A (rs1800629) polymorphism, as well as endothelial nitric oxide synthase (eNOS, NOS3) gene -786T/C (rs2070744), 4a/4b (27 bp-VNTR in intron 4, rs61722009) and 894G/T (Glu298Asp, rs1799983) polymorphisms. METHODS: In total, 188 septic adult cases and 188 healthy controls were enrolled. Genomic DNAs from the controls and patients were analyzed by polymerase chain reaction and restriction fragment length polymorphism methods. RESULTS: There were significant associations between the G/G genotype and G allele of the TNF -308G/A (rs1800629) polymorphism in the sepsis group (p < 0.001). The presence of the T/C genotype (p = 0.002) and C allele (p = 0.001) of the -786T/C (rs2070744) was markedly associated with an increased risk of sepsis. However, no significant associations were found with 4a/4b (27 bp-VNTR in intron 4, rs61722009) and 894G/T (Glu298Asp, rs1799983) polymorphisms. Higher 4bGC and lower 4bTT haplotype frequencies were associated with sepsis. CONCLUSIONS: Our results strongly suggest that TNF gene (-308G/A, rs1800629) and NOS3 gene -786T/C (rs2070744) polymorphisms may modify individual susceptibility to sepsis in the Turkish population.

The effect of Benson relaxation method on anxiety in the emergency care.

OBJECTIVE: To analyze clinical and sociodemographic properties of the patients as measured by the "Hospital Anxiety and Depression Scale-HADS" including the subscale regarding anxiety (HAD-A) in emergency department (ED) and to detect the effect of a session of Benson relaxation method (BRM) on high anxiety level. METHODS: Adult patients presented to the state hospital ED in seven days were recruited in this prospective study. Patients with high (≥8) scores were randomized to the treatment or control groups. They were asked to pursue BRM to alleviate anxiety. RESULTS: Six hundred thirty-four patients were recruited (mean age 44.1 and 52% were female). Patients with acute exacerbation or with psychiatric illness, with a systemic disease and higher acuity level had higher HAD-A scores (P < .05). BRM group had a mean score change higher than controls (7.2 ±â€Š2.9 vs 3.4 ±â€Š2.6, t test, P = .026). CONCLUSIONS: Patients who underwent BRM had larger decreases in HAD-A scores than others.

Emergency department patients' clinical and demographic characteristics regarding Hospital Anxiety subscale.

OBJECTIVE: To evaluate clinical and demographic characteristics of the emergency department (ED) patients using Hospital Anxiety and Depression Scale (HADS) which includes anxiety (HAD-A) subscale. MATERIALS AND METHODS: In this cross-sectional study, all consecutive adult patients admitted to the community hospital-based ED in the study period were enrolled prospectively. HAD-A items were responded by the patients themselves. Demographic characteristics, history, and clinical findings were analyzed. RESULTS: Four hundred and ninety-eight consecutive ED patients with eligible conditions were enrolled. Mean age was 44.1 ± 16.5 (range 18-90) and 53.0% (n = 264) were female. The presence of pathological examination finding was significantly associated with a tendency to have a HAD-A score higher than 10 (p = .044). Presence of systemic disease was significantly associated with higher anxiety scores (t-test, p = .029). Patients presented with acute exacerbation of a chronic illness and those with psychological condition had significantly higher HAD-A scores (p = .014 and p = .008, respectively). CONCLUSIONS: High acuity, presence of pathological finding, higher income, presence of a systemic disease, acute exacerbation of a chronic illness were significantly associated with higher anxiety scores.

The diagnostic value of irisin in patients with acute abdominal pain: A preliminary study.

BACKGROUND: The aim of this study was to investigate the prognostic value of irisin by examining the serum level of this smooth muscle protein in patients presenting at the emergency department (ED) with acute abdominal pain. METHODS: This research was performed as a single-center, prospective, cross-sectional study. In all, 213 adult patients presenting at the ED with acute abdominal pain and 140 healthy controls were enrolled. The serum irisin level was correlated with the leukocyte, C-reactive protein, amylase, and creatine kinase values. The irisin level was compared between groups of those who were admitted or discharged, and those who received surgical or medical treatment. RESULTS: The mean irisin level of the 213 patients and the 140 controls was 6.81±3.17 mcg/mL vs. 5.69±2.08 mcg/mL. The mean irisin value of the hospitalized patients (7.98±3.11 mcg/mL) was significantly higher than that of the discharged patient group (6.38±3.09 mcg/mL) and the controls (control vs. discharged: p=0.202; control vs. hospitalized: p<0.001; discharged vs. hospitalized: p=0.001). When compared with that of the control group, the irisin level was significantly higher in patients with gall bladder diseases, urolithiasis, and acute appendicitis (p=0.001, p=0.007, p=0.007). CONCLUSION: The serum irisin level in patients with abdominal pain may serve as a guide in diagnostic decision-making and determining the prognosis for cases of acute abdominal pain involving luminal obstruction in tubular intra abdominal organs.

Musculoskeletal complaints in healthcare personnel in hospital: An interdepartmental, cross-sectional comparison.

The objective of this study is to investigate musculoskeletal complaints (MSCs) in healthcare workers (HCWs) in 3 community hospital-based departments [internal medicine (IM), general surgery (GS), and emergency department (ED)] and its effects on the quality of work life (QWL) of hospital HCW.This prospective cross-sectional study was performed in the 700-bed community training hospital. All HCW staffed in 3 departments (IM, GS, ED) of the hospital were asked to respond to items in the study data sheet. Enrolled personnel were inquired about their demographic data, work history and schedule, and medical history. The 16-item Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) Turkish version was applied to evaluate MSC. A total of 216 HCW constituted the study sample and demographic characteristics, history, and clinical findings were analyzed.Among all, 103 personnel (47.7%) were women (n = 42, 41.1% in physicians, n = 57, 87.6% in nurses and n = 4, 8% in other HCW) (P = .000). A total of 173 personnel (79.7%) reported MSC in some part of their bodies. Female personnel had MSC significantly more commonly than males (chi-square = 40.7, P = .000). Numbers and percentages of the personnel with MSC in 3 departments (IM, GS, ED) were 51/61, 52/65, and 70/90, respectively (P = .67). Total QWL score of those without MSC was significantly higher than others (74.7 + -12 vs 63.2 + -15, respectively; t test, P = .000). Total frequency score of MSC as elicited via CMDQ was significantly higher in those without MSC compared to the others (8.1 + -7.6 vs 0.1 + -0.6, respectively, t test, P = .000).Female sex, high-income, university graduation, being a nurse or a physician, and older age impose risk for HCW in hospital with respect to having MSC. Presence of MSC affects QWL negatively.

Patients with Acute Stroke Presenting Like Conversion Disorder.

Conversion disorder is a form of somatoform disorders which has a high prevalence among women, individuals with lower socioeconomic status, under-educated populations, and in developing countries. However, up to one-half of patients who had been initially diagnosed with conversion disorder were eventually shown to have an underlying organic pathology-mostly neurological or non-psychiatric conditions. In this article, two patients are presented who accessed the emergency department (ED) with an initial diagnosis of conversion disorder in the ambulance that turned out to be stroke.Serinken M, Karcioglu O. Patients with acute stroke presenting like conversion disorder. Prehosp Disaster Med. 2018;33(4):451-453.

A systematic review of safety and adverse effects in the practice of therapeutic hypothermia.

OBJECTIVE: To carry out a systematic review to estimate the rate and magnitude of adverse effects following therapeutic hypothermia (TH) procedure in patients resuscitated from out-of-hospital cardiac arrest (OHCA) and highlight the specific complications seen after the procedure. METHODS: A systematic review of currently published studies was performed following standard guidelines. Online database searches were performed for controlled trials for the last twenty years. Papers were examined for methodological soundness before being included. Data were independently extracted by two blinded reviewers. Studies were also assessed for bias using the Cochrane criteria. The adverse effects attributed to TH in the literature were appraised critically. RESULTS: The initial data search yielded 78 potentially relevant studies; of these, 59 were excluded for some reason. The main reason for exclusion (n = 43, 55.8%) was that irrelevance to adverse effects of TH. Finally, 19 underwent full-text review. Studies were of high-to-moderate (n = 12, 63%) to low-to-very low (n = 7, 37%) quality. Five studies (27.7%) were found to have high risk of bias, while 8 (42.1%) had low risk of bias. INTERPRETATION: Although adverse effects related to the practice of TH have been studied extensively, there is substantial heterogeneity between study populations and methodologies. There is a considerable incidence of side effects attributed to the procedure, e.g., from life-threatening ventricular arrhythmias to self-limited consequences. Most studies analyzed in this systematic review indicated that the procedure of TH has not caused severe adverse effects leading to significant alterations in the outcomes following resuscitation from OHCA. PROSPERO, registration number is: CRD42018075026.

Intravenous Dexketoprofen versus Intravenous Paracetamol for Dysmenorrhea: A Randomized Controlled Trial

BACKGROUND: Dysmenorrhea is one of the most common acute pain disorders among women of reproductive age. AIMS: To compare the effects of IV paracetamol with dexketoprofen in patients presenting with primary dysmenorrhea to the emergency department. STUDY DESIGN: Randomized controlled trial. METHODS: Patients over 18 years old presenting with pelvic pain related to menstruation were eligible for the study. Study patients received 1 g paracetamol or 50 mg dexketoprofen in 100 mL normal saline with a 4-5 minute infusion via the intravenous route. Pain intensity was measured by a visual analog scale at 15 and 30 minutes. Patients were randomized and assigned to either of two study arms via sealed envelopes. Study drugs were identical in color, and thus both personnel and patients were blinded to the study drug. The dexketoprofen group comprised 49 patients, and the paracetamol group had 50 patients in the final analysis. RESULTS: The mean age of the study subjects was 20.9±2.5 and the mean duration of the pain was 1.9±1.7 (median: 1, interquartile range: 1 to 2) hours. Both dexketoprofen (median change: 33, 95% CI: 24 to 38) and paracetamol (median change: 21, 95% CI: 12 to 32) effectively reduced the pain at 15 minutes, which was repeated at 30 minutes (median change: 63, 95% CI: 57 to 65 vs 55.5, 95% CI: 50 to 59, respectively). Pain improvement in the dexketoprofen group was better than in the paracetamol group at 15 (median difference: 8, 95% CI: 0 to 16, p=0.048) and 30 (median difference: 6, 95% CI: 1 to 12, p=0.028) minutes, which was statistically significant but not clinically significant. CONCLUSION: Dexketotoprofen has a better visual analogue scale score that is not clinically relevant compared to paracetamol.

Longitudinal Clival Fracture in a Child: Case Report and Review of the Literature.

Clival fracture is a rare and serious injury, which mostly results in the death of the victim before reaching the hospital. The entity is hardly diagnosed in the early phase because of high mortality rates and deficiencies in completion of radiological imaging. The incidence of diagnoses increased year by year after the usage of computed tomography gained widespread availability. In this article, we aimed to present radiological and clinical characteristics of a 5-year-old patient brought to the emergency department after a motor vehicle accident. The most current recommendations with regard to the management of clival fracture of a pediatric patient are also discussed.

A systematic review of the pain scales in adults: Which to use?

OBJECTIVE: The study analysed the Visual Analogue Scale (VAS), the Verbal Rating Scale (VRS) and the Numerical Rating Scale (NRS) to determine: 1. Were the compliance and usability different among scales? 2. Were any of the scales superior over the other(s) for clinical use? METHODS: A systematic review of currently published studies was performed following standard guidelines. Online database searches were performed for clinical trials published before November 2017, on the comparison of the pain scores in adults and preferences of the specific patient groups. A literature search via electronic databases was carried out for the last fifteen years on English Language papers. The search terms initially included pain rating scales, pain measurement, pain intensity, VAS, VRS, and NRS. Papers were examined for methodological soundness before being included. Data were independently extracted by two blinded reviewers. Studies were also assessed for bias using the Cochrane criteria. RESULTS: The initial data search yielded 872 potentially relevant studies; of these, 853 were excluded for some reason. The main reason for exclusion (33.7%) was that irrelevance to comparison of pain scales and scores, followed by pediatric studies (32.1%). Finally, 19 underwent full-text review, and were analysed for the study purposes. Studies were of moderate (n=12, 63%) to low (n=7, 37%) quality. CONCLUSIONS: All three scales are valid, reliable and appropriate for use in clinical practice, although the VAS is more difficulties than the others. For general purposes the NRS has good sensitivity and generates data that can be analysed for audit purposes.

Use of lipid emulsion therapy in local anesthetic overdose.

The use of intravenous lipid emulsion (ILE) therapy as antidote in systemic toxicity of certain agents has gained widespread support. There are increasing data suggesting use of ILE in reversing from local anesthetic-induced systemic toxicity severe, life-threatening cardiotoxicity, although findings are contradictory. Efficiency of ILE was demonstrated in animal studies in the treatment of severe impairment of cardiac functions, via a mechanism for trapping lipophilic drugs in an expanded plasma lipid compartment ("lipid sink"). In patients with hemodynamic compromise and/or cardiovascular collapse due to lipid-soluble agents, ILE may be considered for resuscitation in the acute setting by emergency physicians. The most common adverse effects from standard ILE include hypertriglyceridemia, fat embolism, infection, vein irritation, pancreatitis, electrolyte disturbances and allergic reactions. The advantages of ILE include an apparent wide margin of safety, relatively low cost, long shelf-life, and ease of administration.

Work-related Injuries Among Emergency Medical Technicians in Western Turkey.

OBJECTIVES: Emergency medical technicians (EMTs) and paramedics are at serious risk for work-related injuries (WRIs) during work hours. Both EMTs and paramedics have higher WRI rates, according to the literature data. This study was designed to investigate causes and characteristics of WRIs involving EMTs and paramedics staffed in Western Turkey. METHODS: All health care personnel staffed in Emergency Medical Services (EMS) in the city were interviewed face-to-face in their off-duty hours to inform them about the study. Excluded from the study were those who declined to participate in the study, those who were not on duty during the two-month study period, and those who had been working in the EMS for less than one year. The subjects were asked to answer multiple-choice questions. RESULTS: A total of 163 personnel (117 EMTs and 46 paramedics) comprised the study sample. Eighty-three personnel (50.9%) were female and mean age was 29.7 years (SD=8.4 years). The most common mechanisms of WRI, as reported by the personnel, were motor vehicle accidents (MVAs; 31.9%), needlestick injuries (16.0%), ocular exposure to bodily fluids (15.4%), and sharp injuries (9.8%), respectively. Needlestick injuries commonly occurred during intravenous line procedures (59.4%) and inside the cruising ambulance (n=20; 62.5%). Working inside the cruising ambulance was the most commonly accused cause of the WRI (41.3%). CONCLUSION: Paramedic personnel and EMTs are under high risk of WRI. Motor vehicle accidents and needlestick injuries were the most common causes of WRI. Strict measures need to be taken to restructure the interior design to protect personnel from all kinds of WRIs.

Chest X-rays in detecting injuries caused by blunt trauma.

BACKGROUND: The appropriate sequence of different imagings and indications of thoracic computed tomography (TCT) in evaluating chest trauma have not yet been clarified at present. The current study was undertaken to determine the value of chest X-ray (CXR) in detecting chest injuries in patients with blunt trauma. METHODS: A total of 447 patients with blunt thoracic trauma who had been admitted to the emergency department (ED) in the period of 2009-2013 were retrospectively reviewed. The patients met inclusion criteria (age>8 years, blunt injury to the chest, hemodynamically stable, and neurologically intact) and underwent both TCT and upright CXR in the ED. Radiological imagings were re-interpreted after they were collected from the hospital database by two skilled radiologists. RESULTS: Of the 447 patients, 309 (69.1%) were male. The mean age of the 447 patients was 39.5±19.2 (range 9 and 87 years). 158 (35.3%) patients were injured in motor vehicle accidents (MVA). CXR showed the highest sensitivity in detecting clavicle fractures [95%CI 78.3 (63.6-89)] but the lowest in pneuomediastinum [95%CI 11.8 (1.5-36.4)]. The specificity of CXR was close to 100% in detecting a wide array of entities. CONCLUSION: CXR remains to be the first choice in hemodynamically unstable patients with blunt chest trauma. Moreover, stable patients with normal CXR are candidates who should undergo TCT if significant injury has not been ruled out.
