Demographic characteristics and delayed neurological sequelae risk factors in carbon monoxide poisoning.

AIM: Carbon monoxide (CO) is a colorless, odorless gas and tasteless. CO poisoning (COP) is one of the most frequently encountered inhalation poisonings. The most common cause of morbidity in COP is delayed neurological sequelae (DNS). DNS is the occurrence of neuropsychiatric findings within 2-240 days after discharge of patients with COP and there are no definitive diagnostic criteria. The aim of our study is; to determine the risk factors and incidence of DNS. METHOD: Our study is a retrospective, observational study. Patients with the diagnosis of COP in the emergency department between 2015 and 2016 were included in the study. Patients age, gender, findings in the initial physical examination (PE) and neurological examination (NE), blood carboxyhemoglobin (COHb) level, relation between hyperbaric oxygen (HBO) treatment and DNS were assessed. RESULTS: Total of 72 patients were included in the study. Mean age was 33.43 ±â€¯20.89. It was determined that pathological findings in the initial NE are a significant predictive factor for DNS (Odds ratio 18.600, p:0.004). Significant relation between NE and HBO treatment was present (p:00.1). There was no statistically significant relationship between initial COHb level and receiving HBO treatment (p:0.9). Median COHb level of patients with DNS was 30 (min:10, max: 43), median COHb level of patients without DNS was 25 (min:10, max:44) and there was no statistically significant relationship between the two groups according to COHb levels (p:0.7). CONCLUSION: Pathological findings in the initial neurological examination had a predictive value for delayed neurological sequelae in patients with carbon monoxide poisoning.

Comparison of ketamine/propofol (ketofol) and etomidate/fentanyl (etofen) combinations for procedural sedation and analgesia in the emergency department: An observational study.

OBJECTIVES: The primary aim of this study was to report the vital signs, hemodynamic parameters and pain scores of the patients who have received procedural sedation and analgesia (PSA) with either ketofol (combination of ketamine and propofol) or etofen (combination of etomidate and fentanyl) and compare the proportion of patients with airway or respiratory adverse events (AEs) requiring an intervention and calculate the relative risk of AEs with each combination. METHODS: This study is a prospective observational study with survey analysis. All patients received procedural sedation and analgesia (PSA) with either ketofol (combination of ketamine and propofol) or etofen (combination of etomidate and fentanyl) were prospectively observed. Vital and hemodynamic parameters and pain scores of the patients were recorded by automated equipment and visual analog scale (VAS) charts. RESULTS: 112 patients were enrolled, 55 received ketofol and 57 received etofen. All patients with a respiratory AE (n = 27) observed to receive a respiratory intervention. Respiratory AE rate and proportion of patient who required a respiratory intervention were significantly higher with ketofol (p = 0.0029). Overall AE rate, and rates of desaturation, emergence reaction were also significantly higher in ketofol group. CONCLUSION: Etofen is a promising combination for the PSA of adult patients with lower respiratory AE and intervention rates and with better hemodynamic profile.

Are scoring systems sufficient for predicting mortality due to sepsis in the emergency department?

OBJECTIVES: Scoring systems have been used to risk stratify in intensive care units (ICU), but not routinely used in emergency departments. The aim of this study was to determine accuracy for predicting mortality in emergency medicine with Sequential Organ Failure Assessment (SOFA), Mortality in ED Sepsis (MEDS) score and Simplified Acute Physiology Score (SAPSII). METHODS: This is a prospective observational study. Patients presenting with evidence of sepsis were all included. SAPSII, MEDS, and SOFA scores were calculated. Analysis compared areas under the receiver operator characteristic (ROC) curves for 28-day mortality. RESULTS: Two hundred patients were included; consisting of 31 (14.3%) septic shock. 138 (69%) severe sepsis and 31 (15.5%) infection without organ dysfunction. 53 (26.5%) patients died within 28 days. Area under the ROC curve for mortality was 0.76 for MEDS (0.69-0.82), 0.70 for SAPSII (0.62-0.78); and 1.68 for SOFA (0.60-0.76) scores. Pair wise comparison of AUC between MEDS, SAPSII, SOFA and Lactate were not significant. CONCLUSION: According to our results; SOFA, SAPSII and MEDS were not sufficient to predict mortality. Also this result, MEDS was better than other scoring system.

A Non-invasive Method for Assessment of Intravascular Fluid Status: Inferior Vena Cava Diameters and Collapsibility Index.

OBJECTIVE: To evaluate the correlation between central venous pressure (CVP) and inferior vena cava (IVC) diameters measured by ultrasonography (Ultrasound) in critically ill patients. METHODS: Intubated critically ill patients were enrolled. The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultrasound. Patients younger than 18 years old, who were not intubated, who had an abdominal pressure greater than 12 mmHg, and/or who were admitted for trauma were excluded from the study. RESULTS: Eighty three patients with a mean age of 73.6±11.2 years were enrolled. The most common diagnosis was sepsis (21 patients, 25.30%). IVC inspiration measurements were statistically significantly correlated with CVP measurements (p0.05, r: 0.1). IVC collapsibility measurements showed a negative correlation with CVP measurements (p<0.01, r: 0.68). CONCLUSIONS: There is a strong correlation between CVP and IVC diameters and the collapsibility index. This is a new formula for evaluating CVP, based on our statistical analyses.

TRIMETHOPRIM-SULFAMETHOXAZOLE RESISTANCE AND FOSFOMYCIN SUSCEPTIBILITY RATES IN UNCOMPLICATED URINARY TRACT INFECTIONS: TIME TO CHANGE THE ANTIMICROBIAL PREFERENCES.

Urinary tract infections (UTIs) are among the most common bacterial infections in adult population. They are prevalent in all age groups both in women and men. Also, UTIs are the most frequent indication for empirical antibiotic treatment in emergency department. The aim of this study was to determine the antibiotic resistance rates in the treatment of uncomplicated UTIs. Adult patients admitted to emergency department with uncomplicated UTIs were included in this cross-sectional study. Mid-stream urine samples were obtained under sterile conditions and cultured quantitatively. After 24 hours, the samples showing 10(5) colony forming unit per milliliter (CFU/mL) were tested for antibiotic susceptibility. Resistance to fosfomycin-trometamol (FT), amoxicillin-clavulanic acid (AC), ciprofloxacin (CIP), trimethoprim-sulfamethoxazole (TMP-SMX) and cefpodoxime (CEF) was tested by Kirby-Bauer disc diffusion system. Escherichia (E.) coli accounted for the vast majority (93.4%) of the organisms isolated in the study. Among the E. coli positive patients, resistance to TMP-SMX was the most common antibiotic resistance. The E. coli species detected in our study group were least resistant to FT (2.4%). The resistance rates, especially to CEF, AC and CIP, were significantly higher in patients over 50 years of age. In conclusion, in the treatment of uncomplicated UTIs, TMP-SMX should be excluded from empirical treatment, while fosfomycin could be a viable option in all age groups.

Tracheal ultrasonography and ultrasonographic lung sliding for confirming endotracheal tube placement: Speed and Reliability.

BACKGROUND: In this study we aimed to evaluate the success of ultrasonography (USG) for confirming the tube placement and timeliness by tracheal USG and ultrasonographic lung sliding in resuscitation and rapid sequence intubation. MATERIALS AND METHODS: This study was a prospective, single-center, observational study conducted in the emergency department of a tertiary care hospital. Patients were prospectively enrolled in the study. Patients who went under emergency intubation because of respiratory failure, cardiac arrest or severe trauma included in the study. Patients with severe neck trauma, neck tumors, history of neck operation or tracheotomy and under 18years old were excluded from the study. RESULTS: A total of 115 patients included in the study. The mean age was 67.2±17.1 with age 16-95years old. Among 115 patients 30 were cardiac arrest patients other 85 patients were non-cardiac arrest patients intubated with rapid sequence intubation. The overall accuracy of the ultrasonography was 97.18% (95% CI, 90.19-99.66%), and the value of kappa was 0.869 (95% CI, 0.77-0.96), indicating a high degree of agreement between the ultrasonography and capnography. The ulrasonography took significantly less time than capnography in total. DISCUSSION: Ultrasonography achieved high sensitivity and specificity for confirming tube placement and results faster than end-tidal carbon dioxide. Ultrasonography is a good alternative for confirming the endotracheal tube placement. Future studies should examine the use of ultrasonography as a method for real-time assessment of endotracheal tube placement by emergency physicians with only basic ultrasonographic training.

Intravenous Lipid Emulsion Therapy for Acute Synthetic Cannabinoid Intoxication: Clinical Experience in Four Cases.

There is no specific antidote for intoxication with synthetic cannabinoids. In this case series, we considered the efficiency of intravenous lipid emulsion therapy in four cases, who presented to emergency department with synthetic cannabinoid (bonzai) intoxication. The first patient had a GCS of 3 and a left bundle branch block on electrocardiography. The electrocardiography revealed sinus rhythm with normal QRS width after the treatment. The second patient had bradycardia, hypotension, and a GCS of 14. After intravenous lipid emulsion therapy, the bradycardia resolved, and the patient's GCS improved to 15. The third patient presented with a GCS of 8, and had hypotension and bradycardia. After the treatment, not only did the bradycardia resolve, but also the GCS improved to 15. The fourth patient, whose electrocardiography revealed accelerated junctional rhythm, had a GCS of 13. The patient's rhythm was sinus after the treatment. Cardiovascular recovery was seen in all four cases, and neurological recovery was also seen in three of them. Based on the fact that intravenous lipid emulsion is beneficial in patients intoxicated with lipophilic drugs, unstable patients presenting to the emergency department with acute synthetic cannabinoid intoxication may be candidates for intravenous lipid emulsion treatment.

Rising Threat; Bonsai.

OBJECTIVES: In recent years, and especially in the past few months, the number of synthetic cannabinoid (bonsai) users has increased in our country. The aim of this study was to draw attention to the consumption of bonsai among young people and reveal the demographic and basic clinical characteristics of these users. METHODS: This was a retrospective study conducted at the Ümraniye Training and Research Hospital. All of the adult patients (≥18 year old) with synthetic cannabinoid intoxication who presented to the Emergency Department throughout the two years of the study (July 1(st) 2012-June 30(th) 2014) were enrolled. The frequencies were given as the median and inter-quartile range). RESULTS: 197 patients were included in this study, with 190 male patients (96.4%) and 7 (3.6%) female patients. Two of the four hospitalized patients were exitus, 52 left on their own will and a total of 141 patients were discharged after 6-12 hours of observation in the ED. CONCLUSIONS: The use of synthetic cannabinoids (bonsai) in the recent years, especially in the summer months of 2014 was investigated in this study. Although these patients can have a benign clinical course, the process can also be fatal. It should especially be noted that patients with depressed respiration, low GCS scores and high PaCO2 values are at higher risk for mortality and the necessity of early intubation should be kept in mind.

A case of acute hepatitis following mad honey ingestion.

Acute hepatitis is characterized by liver inflammation and liver cell necrosis. The most frequently observed underlying cause thereof is viruses, but various other causes, such as alcohol, medication, or toxins may also lead thereto. In this paper, a case of acute hepatitis presenting with bradycardia, hypotension, and a prominent increase in liver enzymes following mad honey ingestion is discussed. Since there are only few cases of acute hepatitis following mad honey ingestion in the literature, we want to present this subject matter.

Hepatitis B, Hepatitis C and HIV seroprevalence in critically ill emergency medicine department patients in a tertiary inner city hospital in Istanbul, Turkey.

OBJECTIVE: Emergency medicine staff is working at risk of blood-borne infections during their daily practice every time. The risk of transmission is higher when dealing with critically ill patients. Our objective was to find out the prevalence of Hepatitis B, Hepatitis C, and HIV, in critically ill red-coded emergency department patients. METHODS: The study was carried out as prospective observational study between 1 September 2012 and 31 January 2013 in a tertiary inner city hospital emergency department in Istanbul, Turkey. Red triage coded patients managed in resuscitation room were enrolled. RESULTS: One thousand patients were included during the study period. Fifty of them were HBV positive. Eighteen patients were HCV positive and 2 had both HBV and HCV. HIV was not recorded. Forty one of them were trauma patients. There were 226 unconscious or uncooperative patients. Prior blood transfusion history was present in 92 of the patients and among them 11 had HBV and 3 had HCV. Four patients or their relatives were aware of their HCV positivity. HBV positivity was already known by the patients or their relatives. Total HBV vaccination ratio was 7.4%. CONCLUSION: Prevalence of HCV (1.8%) and HBV(5%) seroprevalence in our study group was very low which correlated with the recent literature regarding the Turkish population. HIV was not detected during the study period. This may also be accepted as consistent with the very low number of reported cases in Turkey.

Intralipid emulsion treatment as an antidote in lipophilic drug intoxications.

Intravenous lipid emulsion (ILE) is a lifesaving treatment of lipophilic drug intoxications. Not only does ILE have demonstrable efficacy as an antidote to local anesthetic toxicity, it is also effective in lipophilic drug intoxications. Our case series involved 10 patients with ingestion of different types of lipophilic drugs. Intravenous lipid emulsion treatment improved Glasgow Coma Scale or blood pressure and pulse rate or both according to the drug type. Complications were observed in 2 patients (minimal change pancreatitis and probable ILE treatment-related fat infiltration in lungs). In our case series, ILE was used for different lipophilic drug intoxications to improve cardiovascular and neurologic symptoms. According to the results, it was found that ILE treatment is a lifesaving agent in lipophilic drug intoxications and it can be used in unconscious patients who have cardiac and/or neurologic symptoms but no history of a specific drug ingestion.

Endoscopic gastrostomy, nasojejunal and oral feeding comparison in aspiration pneumonia patients.

BACKGROUND: Aspiration pneumonia is a potentially preventable illness requiring attention to small details of patient care. The type, management, and care of feeding should be carried out properly. MATERIALS AND METHODS: This is a prospective clinical study of enteral feeding on patients admitted to hospital with aspiration pneumonia. The known enteral nutritional methods, advantages, and disadvantages were told to the patient or proxy. If they didn't accept Percutaneous endoscopic gastrostomy (PEG), nasojejunal tube (NJT) was advised. If they denied all of the procedures, oral feeding education was given. A total of 94 patients were enrolled to the study, 29 of them accepted PEG, 42 preferred NJT, and 23 preferred oral route. RESULTS: A total of 94 patients with a mean age of 77.84, standard deviation 10.784; 95% confidence interval (CI) 75.63-80.03 were enrolled to the study of which 27 (28.7%) patients had a history of aspiration pneumonia. Oral feeding was prominently preferred for patients nursed by a relative (15; 65.2% of Oral feeding group and 16% of total) or a caregiver (7; 30.4% of Oral feeding group and 7.4% of total) while only 1 (4.3% of Oral feeding group and 1.1% of total) with a health-care worker (P = 0.001). Overall re-aspiration rates at the 6(th) month were 58%, 78%, 91% in EG, NJT, oral groups, respectively. Sixth months' survival rates of the different feeding groups were not significantly divergent from each other. History of aspiration was also found to be a significant contributor of mortality. CONCLUSION: In aspiration pneumonia patients' long-term survival rates of the different feeding groups were not significantly divergent from each other.

Determination of the appropriate catheter length and place for needle thoracostomy by using computed tomography scans of pneumothorax patients.

INTRODUCTION: The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX. MATERIALS AND METHODS: All trauma patients who presented consecutively to A&E over a 12-month period were included. Among all the trauma patients with a chest CT (4204 patients), 160 were included in the final analysis. CWTs were measured at both sides and were compared in all subgroup of patients. RESULTS: The average CWT for men on the 2nd ICS-MCL was 38mm and for women was 52mm; on the other hand, on the 5th ICS-MAL was 33mm for men and 38mm for women. On the 2nd ICS-MCL 17% of men and 48% of women; on the 5th ICS-MAL 13% of men and 33% of women would be inaccessible with a routine 5-cm catheter. Patients with trauma, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 2nd ICS-MCL. Patients with trauma, lung contusion, sternum fracture, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 5th ICS-MAL. CONCLUSIONS: This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.

Utility of cervical spinal and abdominal computed tomography in diagnosing occult pneumothorax in patients with blunt trauma: Computed tomographic imaging protocol matters.

BACKGROUND: Small pneumothoraces (PXs), which are not initially recognized with a chest x-ray film and diagnosed by a thoracic computed tomography (CT), are described as occult PX (OCPX). The objective of this study was to evaluate cervival spine (C-spine) and abdominal CT (ACT) for diagnosing OCPX and overt PX (OVPX). METHODS: All patients with blunt trauma who presented consecutively to the emergency department during a 26-months period were included. Among all the chest CTs (CCTs) (6,155 patients) conducted during that period, 254 scans were confirmed to have a true PX. The findings in their C-spine CT and ACT were compared with the findings in CCTs. RESULTS: Among these patients, 254 had a diagnosis of PX confirmed with CCT. OCPXs were identified on the chest computed tomographic scan of 128 patients (70.3%), whereas OVPXs were evident in 54 patients (29.7%). Computed tomographic imaging of the C-spine was performed in 74% of patients with OCPX and 66.7% of patients with OVPX trauma. Only 45 (35.2%) cases of OCPX and 42 (77.8%) cases of OVPX were detected by C-spine CT. ACT was performed in almost all patients, and 121 (95.3%) of 127 of these correctly identified an existing OCPX. Sensitivity of C-spine CT and ACT was 35.1% and 96.5%, respectively; specificity was 100% and 100%, respectively. CONCLUSION: Almost all OCPXs, regardless of intrathoracic location, could be detected by ACT or by combining C-spine and abdominal computed tomographic screening for patients. If the junction of the first and second vertebra is used as the caudad extent, C-spine CT does not have sufficient power to diagnose more than a third of the cases. LEVEL OF EVIDENCE: Diagnostic study, level III.

Tension pneumoperitoneum complicated with tension pneumothorax in a patient with diaphragmatic eventration.

Tension pneumothorax complicating a pneumoperitoneum is a rare but known entity. However, all previously published articles report an air leak through defects in the diaphragm connecting the pneumoperitoneum and the pneumothorax. Here, the case of a 36-year-old man in whom the pneumoperitoneum acted like a tension pneumothorax because of a congenital eventration of the left diaphragm without penetration is presented. Emergency needle decompression of the abdomen was performed. A gastric ulcer that had passed through the diaphragm to the right lung was diagnosed intraoperatively. Unfortunately, the patient developed a ventricular fibrillation that remained resistant to all resuscitative efforts, and the patient died shortly afterwards.

Potassium permanganate ingestion as a suicide attempt.

Potassium permanganate is a highly corrosive, water-soluble oxidizing antiseptic. A 68-year-old female patient was admitted to our Emergency Department after ingestion of 3 tablets of 250 mg potassium permanganate as a suicide attempt. The physical exam revealed brown stained lesions in the oropharynx. Emergency endoscopy was performed by the gastroenterologist after the third hour of ingestion. Emergency endoscopy revealed multiple superficial (Grade I-II) lesions on the esophagus and cardia, which were considered secondary to the caustic substance. The mainstay in the treatment of potassium permanganate is supportive and the immediate priority is to secure the airway. Emergency endoscopy is an important tool used to evaluate the location and severity of injury to the esophagus, stomach and duodenum after caustic ingestion. Patients with signs and symptoms of intentional ingestion should undergo endoscopy within 12 to 24 h to define the extent of the disease.

Spontaneous isolated celiac artery dissection.

Dyspepsia with mild, stabbing epigastric discomfort without history of trauma is a very common symptom that emergency physicians see in their daily practice. Vascular emergencies, mostly the aortic dissection and aneurysm, are always described in the differential diagnosis with persistent symptoms. Isolated celiac artery dissection occurring spontaneously is a very rare diagnosis. The involvement of branch vessels is generally observed and patients show various clinical signs and symptoms according to the involved branch vessel. Here we are presenting a case with spontaneous isolated celiac artery dissection, without any branch vessel involvement or visceral damage, detected by computed tomography scans taken on admission.

Investigation of the association between dopamine D1 receptor gene polymorphisms and essential hypertension in a group of Turkish subjects.

Dopamine has been shown to influence blood pressure by regulating renal sodium excretion through direct interaction with the dopamine receptors, especially with the Dopamine D1 receptor (DRD1). To better understand the role of polymorphisms in those effects, we investigated the association between two polymorphic sites in the DRD1 promoter region (A-48G, G-94A) and essential hypertension in the Turkish population. The DRD1 variants were genotyped by restriction fragment length polymorphism (RFLP) analysis. A total of 205 unrelated individuals were enrolled in the study. We found that genotype distributions and allele frequencies of the control and hypertensive subjects were very similar and did not show any significant difference with respect to blood pressure (BP) and hypertension. Contribution of the gene variances in BP or hypertension by sex differences and dependence on body mass index (BMI) were also evaluated. Distribution of genotypes and allele frequencies were found to be in line with previous reports. However, increments detected in hypertensive subjects were far from being statistically significant.

The role of G protein ß3 subunit polymorphisms C825T, C1429T, and G5177A in Turkish subjects with essential hypertension.

Hypertension is a multifactorial disorder that constitutes a major risk factor for the cardiovascular system. Heterotrimeric G-proteins, which couple receptors for diverse extracellular enzymes or ion channels, are correlated with disease mechanisms. Several studies have demonstrated an association between G protein polymorphisms and essential hypertension in some populations, although contradictive results also exist. In this study, we have investigated the potential role of the C825T, C1429T, and G5177A polymorphisms of the ß3 subunit of G-proteins in essential hypertension in a group of Turkish subjects. Genomic DNA from 106 normotensive individuals (117.4 ± 13.1, 75.2 ± 10.5; systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels, respectively) and 101 hypertensive subjects (152.3 ± 18.0, 92.5 ± 11.6; SBP and DBP levels, respectively) were studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct sequencing methods for these polymorphisms. Allele frequencies of the polymorphisms were consistent with Hardy Weinberg equilibrium, except for the C825T polymorphism (χ(2) = 7.8). The frequencies of the 825T and 1429T variants were higher in hypertensive subjects compared to those of controls. Differences between hypertensives and controls were not statistically significant, though difference was very close to significance for C825T (p = 0.056 and 0.099 for 825T and 1429T, respectively). T allele frequency in overall population showed significant association with hypertension for C825T (0.0134). The prevalence of the 5177A-variant was very low and all subjects carrying it were heterozygotes in both groups.

Can NT-proBNP be used as a criterion for heart failure hospitalization in emergency room?

BACKGROUND: Heart failure is a common health problem with poor prognosis. The gold standard for diagnosis is echocardiography but it is not always reachable, especially in emergency conditions. NT-pro-brain natriuretic peptide (NT-proBNP) is a novel indicator for the diagnosis of heart failure and is being used in routine tests in emergency rooms. This study was conducted to compare NT-proBNP levels between hospitalized congestive heart failure (CHF) patients and outpatients. METHODS: This study was designed as a single-centre, prospective, and controlled trial. Blood samples and data were collected from a total of 119 patients with shortness of breath admitted to Department of Emergency, School of Medicine, Marmara University. Patients were primarily diagnosed with decompensated heart failure according to the Framingham criteria and aged above 18 years. A total of 92 patients were included in the study after exclusions. NT-proBNP measurements were made by immune fluorescent method. Available data were compared between hospitalized patients and outpatients. RESULTS: NT-proBNP levels were significantly higher in hospitalized patients compared to outpatients, and this finding was correlated with the clinical status of the patients. The mean NT-proBNP value of the patients was 9741.9 ± 8973 pg/ml (range: 245-35000) while the mean NT-proBNP value of patients diagnosed with non-decompensated congestive heart failure was 688.9 ± 284.5 pg/ml (range: 115-1450.65). CONCLUSIONS: NT-proBNP can be used as an easy diagnostic method for congestive heart failure. A certain cut-off value may be determined in further multi-centre controlled trials with larger patient groups.
