The factors predicting pneumonia in COVID-19 patients: preliminary results from a university hospital in Turkey

Background/aim: Pneumonia is the most serious clinical presentation of COVID-19. This study aimed to determine the demographic, clinical, and laboratory findings that can properly predict COVID-19 pneumonia. Materials and methods: This study was conducted in the Gazi University hospital. All hospitalized patients with confirmed and suspected SARS-CoV-2 infection between 16 March 2020 and 30 April 2020 were analyzed retrospectively. COVID-19 patients were separated into two groups, pneumonia and nonpneumonia, and then compared to determine predicting factors for COVID-19 pneumonia. Variables that had a P-value of less than 0.20 and were not correlated with each other were included in the logistic regression model. Results: Of the 247 patients included in the study 58% were female, and the median age was 40. COVID-19 was confirmed in 70.9% of these patients. Among the confirmed COVID-19 cases, 21.4% had pneumonia. In the multivariate analysis male sex (P = 0.028), hypertension (P = 0.022), and shortness of breath on hospital admission (P = 0.025) were significant factors predicting COVID-19 pneumonia. Conclusion: Shortness of breath, male sex, and hypertension were significant for predicting COVID-19 pneumonia on admission. Patients with these factors should be evaluated more carefully for diagnostic procedures, such as thorax CT.

BLUE protocol ultrasonography in Emergency Department patients presenting with acute dyspnea.

OBJECTIVE: Dyspnea is a common Emergency Department (ED) symptom requiring prompt diagnosis and treatment. The bedside lung ultrasonography in emergency (BLUE) protocol is defined as a bedside diagnostic tool in intensive care units. The aim of this study was to investigate the test performance characteristics of the BLUE-protocol ultrasonography in ED patients presenting with acute dyspnea. METHOD: This study was performed as a prospective observational study at the ED of a tertiary care university hospital over a 3-month period. The BLUE-protocol was applied to all consecutive dyspneic patients admitted to the ED by 5 emergency physicians who were certified for advanced ultrasonography. In addition to the BLUE-protocol, the patients were also evaluated for pleural and pericardial effusion. RESULTS: A total of 383 patients were included in this study (mean age, 65.5 ±â€¯15.5 years, 183 (47.8%) female and 200 (52.2%) male). According to the BLUE-protocol algorithm, the sensitivities and specificities of the BLUE-protocol are, respectively, 87.6% and 96.2% for pulmonary edema, 85.7% and 99.0% for pneumonia, 98.2% and 67.3% for asthma/COPD, 46.2% and 100% for pulmonary embolism, and 71.4% and 100% for pneumothorax. Although not included in the BLUE-protocol algorithm, pleural or pericardial effusion was detected in 82 (21.4%) of the patients. CONCLUSION: The BLUE-protocol can be used confidently in acute dyspneic ED patients. For better diagnostic utility of the BLUE-protocol in EDs, it is recommended that the BLUE-protocol be modified for the assessment of pleural and pericardial effusion. Further diagnostic evaluations are needed in asthma/COPD groups in terms of the BLUE-protocol.

Evaluation of the general characteristics of patients aged 85 years and above admitted to a university hospital emergency department

Background/aim: The number of elderly people (≥65 years old) is increasing both in Turkey and internationally due to improved living conditions and decreased mortality rates. Knowing the characteristics of elderly patients admitted to emergency departments can provide guidance for diagnosis and treatment approaches. In this study, we analyzed the characteristics of very old patients (4≥85 years old) admitted to the emergency department and put together data for use in forward planning in healthcare services.Materials and methods: This retrospective study included all patients aged ≥85 years admitted to the Adult Emergency Department of Gazi University Medical Faculty Hospital between 01.01.2014 and 31.12.2014. Data concerning the patients' age, sex, date of admission, weekday or weekend admission, reason for admission, length of stay, number of readmissions, admission from within or outside the province, and whether they were hospitalized or not were evaluated.Results: In this study, 1105 admissions of 780 patients aged ≥85 years to the emergency department were analyzed. The median age of the patients was 87 years and 59% were female. The most frequent admissions were in January (11.4%). Most patients (63.1%) were admitted only once to our emergency department within the study period. A total of 40.5% of patients were hospitalized in the clinics or intensive care units. The rate of mortality at first admission was 1.5% (12 patients). The most common complaints at admission were infection (13.3%) and soft tissue traumas (crashes, sprains, fractures, dislocations) related to the musculoskeletal system (11.8%). Readmissions were more frequent in males. It was seen that male patients were more frequently admitted due to deterioration of general health status and genitourinary system symptoms, despite pain being more common among women.Conclusion: Due to the changing population structure, emergency staff in Turkey as well as internationally encounter old and very old patients more frequently. It is now imperative that emergency departments acquire the necessary infrastructure, human resources, knowledge, and equipment needed to meet the needs of these patients.

Effects of fast-track in a university emergency department through the National Emergency Department Overcrowding Study.

OBJECTIVE: To determine the impact of a fast track area on emergency department crowding and its efficacy for non-urgent patients. METHODS: The prospective cross-sectional study was conducted in an adult emergency department of a university-affiliated hospital in Turkey from September 17 to 30, 2010. Non-urgent patients were defined as those with Canadian Triage Acuity Scale category 4/5. The fast track area was open in the emergency department for one whole week, followed by another week in which fast track area was closed. Demographic information of patients, their complaints on admission, waiting times, length of stay and revisits were recorded. Overcrowding evaluation was performed via the National Emergency Department Overcrowding Study scale. In both weeks, the results of the patients were compared and the effects of fast track on the results were analysed. Continuous variables were compared via student's t test or Mann Whitney U test. Demographic features of the groups were evaluated by chi-square test. RESULTS: A total of 249 patients were seen during the fast track week, and 239 during the non-fast track week at the emergency department. Satisfaction level was higher in the fast track group than the non-fast track group (p < 0.001). The waiting times shortened from 20 minutes to 10 minutes and length of stay shortened from 80 minutes to 42 minutes during the fast track week. Morbidity and mortality rates remained unchanged. CONCLUSION: Owing to fast track, overcrowding in the emergency department was lessened. It also improved effectiveness and quality measures.

Determining the diagnostic value of endogenous carbon monoxide in chronic obstructive pulmonary disease exacerbations.

OBJECTIVE: To determine whether endogenous carbon monoxide levels in exacerbations of Chronic Obstructive Pulmonary Disease patients were higher compared to healthy individuals and to investigate alteration of carbon monoxide levels across the three different severity stages of Global Initiative for Chronic Obstructive Lung Disease criteria related to Chronic Obstructive Pulmonary Disease exacerbations. METHODS: The prospective study was conducted from January to March 2011 at two medical institutions in Ankara, Turkey, and comprised patients of acute Chronic Obstructive Pulmonary Disease exacerbations. The severity of the exacerbations was based on the Global Initiative for Chronic Obstructive Lung Disease criteria. Patients with active tobacco smoking, suspicious carbon monoxide poisoning and uncertain diagnosis were excluded. healthy control subjects who did not have any comorbid diseases and smoking habitus were also enrolled to compare the differences between carboxyhaemoglobin levels A two-tailed Mann-Whitney U test with Bonferroni correction was done following a Kruskal-Wallis test for statistical purposes. RESULTS: There were 90 patients and 81 controls in the study. Carboxyhaemoglobin levels were higher in the patients than the controls (p < 0.001). As for the three severity stages, Group 1 had a median carboxyhaemoglobin of 1.6 (0.95- 2.00). The corresponding levels in Group 2 (1.8 [1.38-2.20]) and Group 3 (1.9 [1.5-3.0]) were higher than the controls (p < 0.001 and p < 0.005 respectively). No statistically significant difference between Group 1 and the controls (1.30 [1.10-1.55]) was observed (p < 0.434). CONCLUSION: Carboxyhaemoglobin levels were significantly higher in exacerbations compared with the normal population. Also, in more serious exacerbations, carboxyhaemoglobin levels were significantly increased compared with healthy individuals and mild exacerbations.

Wells score and Pulmonary Embolism Rule Out Criteria in preventing over investigation of pulmonary embolism in emergency departments.

INTRODUCTION: Unnecessary diagnostic tests are usually ordered to most of the patients with dyspnea or pleuritic chest pain, because of the worse outcomes of missed diagnosis of pulmonary embolism (PE). To identify rates and causes of over investigation for PE and to search whether it was possible to reduce this over investigation by using Wells score and Pulmonary Embolism Rule Out Criteria (PERC). MATERIALS AND METHODS: A retrospective observational cohort study performed in an emergency department of a tertiary care university hospital. All patients who were ordered diagnostic with the suspicion of PE were included in the study. They were grouped into two as PE (+) and PE (-) and compared. RESULTS: Among 108 patients, 53 (49%) were diagnosed as PE (+) and overdiagnosis was present in 55 (51%) patients i.e., PE (-). The sensitivity of high Wells score was 43%, specificity 78%, positive predictive value 66% and negative predictive value 59%. PERC criteria found to be negative (when all of the eight criteria were fulfilled) in only five patients. The sensitivity of the test was 98%, specificity 7%, positive predictive value 50%, negative predictive value 80%. When individual parameters of PERC were evaluated solely for the exclusion of PE; "no leg swelling" and "no previous deep venous thrombosis or PE history" were found significantly negatively correlated with PE diagnosis (p= 0.001, r= -0.325 and p= 0.013, r= -0.214 respectively). CONCLUSION: Over investigation of PE in emergency departments still remains as an important problem. In order to prevent this, the clinical prediction rules must be developed further and their use in combination should be searched in future studies.

Endogenous carboxyhemoglobin concentrations in the assessment of severity in patients with community-acquired pneumonia.

INTRODUCTION: Previous studies have shown that carbon monoxide, which is endogenously produced, is increased in community-acquired pneumonia (CAP). However, it has not been studied enough whether severity of pneumonia is correlated with increased carboxyhemoglobin (COHb) concentrations in CAP. The aim of this study was to determine whether endogenous carbon monoxide levels in patients with CAP were higher compared with the control group and, if so, to determine whether COHb concentrations could predict severity in CAP. MATERIALS AND METHODS: Eighty-two patients with CAP were evaluated in this cross-sectional study during a 10-month period. Demographic data, pneumonia severity index and confusion, uremia, rate respiratory, pressure blood, age>65 (CURB-65) scores, hospital admission or discharge decisions, and 30-day hospital mortality rate were recorded. In addition, 83 control subjects were included to study. The COHb concentration was measured in arterial blood sample. RESULTS: The levels of COHb in patients with CAP were 1.70% (minimum-maximum, 0.8-3.2), whereas those in control subjects, 1.40% (minimum-maximum, 0.8-2.9). The higher COHb concentrations in patients with CAP were statistically significant (P < .05). Concentration of COHb correlated with pneumonia severity index (P = .04, r = 0.187); however, it did not correlate with CURB-65 (P = .218, r = 0.112). CONCLUSION: Although COHb concentrations show an increase in patients with pneumonia, it was concluded that this increase did not act as an indicator in diagnosis process or prediction of clinical severity for the physicians.

Mean platelet volume as a risk stratification tool in the emergency department for evaluating patients with ischaemic stroke and TIA.

OBJECTIVE: To investigate the variations of mean platelet volume in patients with ischaemic cerebrovascular complaints, and to find out its diagnostic utility in an acute setting to help risk stratification in patients with ischaemic stroke and transient ischaemic attacks. METHODS: The prospective cross-sectional study was conducted at the Gazi University Hospital, Ankara, Turkey, from November 2009 to June 2010. It comprised 143 consecutive patients of acute ischaemic stroke, 39 patients of transient ischaemic attacks and 60 healthy volunteers. SPSS 13 was used for statistical analysis, and so were t-test, one-way analysis of variance test and correlation analysis. Statistical significance was accepted at p < 0.05. RESULTS: Mean platelet volume results were significantly higher in patients with cortical infarction and transient ischaemic attack compared to the control group (p < 0.001 and p <0.002). A statistically significant increase was also noted in hospitalised patients when compared with discharged patients from the emergency department (p < 0.036). A weak positive correlation was identified between the National Institute of Health Stroke Scores and mean platelet volume levels (r = 0.207; p < 0.001). A significant relationship was identified between mean platelet volume levels and previous stroke (p < 0.005). CONCLUSION: The measurement of mean platelet volume levels may provide useful diagnostic and prognostic information to emergency physicians caring for patients with transient ischaemic attack and ischaemic stroke. In patients with suspected neurological ischaemic symptoms, high levels may be considered as an atherosclerotic risk factor.

Efficacy of triage by paramedics: a real-time comparison study.

OBJECTIVES: Triage has evolved as an effective method of separating patients who require immediate medical attention from patients with non-urgent problems. The aim of this study was to assess the agreement between paramedics and emergency residents about triage decisions using the 3-level triage (3L) system and the 5-level (5L) Australian triage scale in real time. METHODS: All patients who presented to a central triage area during a 1-week period were triaged by paramedics and emergency residents. The chance-adjusted measure of agreement kappa (κ) was calculated to evaluate the agreement between triage decisions made by paramedics and by emergency residents. RESULTS: A total of 731 patients were included in the final data analysis. Admitting time and waiting time were significantly consistent in the triage area. Agreement between the triage decisions made by paramedics and by emergency residents was 47% (κ = 0.47) when using the 3L triage scale and 45% (κ = 0.45) when using the 5L triage scale across all cases. A strong correlation existed among the general conditions of the patients, the 3L triage scale, and the 5L triage scale. DISCUSSION: Triaging is commonly performed by nurses in the American emergency system, and triage by paramedics is not common. Few studies are available about triage by paramedics, and more studies are necessary. A new triage scale may be necessary for untrained personnel so that all emergency departments can conduct simple triage.

The characteristics of assaulted victims presented to a university emergency department: Can head trauma in male patients be considered a clue for assaults?

BACKGROUND: Violence is a common issue without an exact number worldwide. The types are interpersonal, spousal, or domestic violence. We aim to reveal the demographic characteristics of cases involving violence, mechanisms of injury, and their relationship with head and face trauma. METHODS: The files of patients presented to our University Hospital Adult Emergency Department (ED) between January 2018 and December 2020 after an assault were reviewed retrospectively. The data were analyzed with SPSS 20.0. The demographic findings, injury mechanisms, and affected areas were reported. The Chi-square test tested the differences between the groups, and p<0.05 was considered significant. RESULTS: Among the 1280 patients presented after an assault, 71% were male with a median age of 32 (IQR 25-43). In 84% of the cases, the perpetrators were unknown, while their spouses were the perpetrators in 9% of the cases. The place was most noted as home (11%). The methods used were struggling (43%) and punching (42%). The most common affected area was the head (70%) and diagnosis for nasal fracture (4%); two patients had epidural bleeding, and one had a pneumothorax. Males were more common in the 20-40 age groups (χ2, p=0.003). Most of the female victims were battered by their spouses (χ2, p<0.001). Head injury was found in 83% of patients with high blood alcohol levels (χ2, p<0.001) and 75% of male patients had head injuries (χ2, p<0.001). CONCLUSION: Assault is a common problem predominantly among young males. The most commonly affected body part was the head, and nasal fractures were the diagnosis. Most of the patients with high blood levels were among the male victims. The perpetrator of the female victims was their spouses. In the ED, male patients who presented with head trauma were considered as assault victims.

The relationship between upper extremity functional performance and anthropometric features and the quality criteria of cardiopulmonary resuscitation.

Objectives: This study aims to examine the effect of upper extremity performance using the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) on cardiopulmonary resuscitation (CPR) quality criteria according to the European Resuscitation Council (ERC) Guidelines for Resuscitation 2015, including chest compression rate, depth, and recoil. Patients and methods: This simulation-based study included 105 paramedic students (43 males, 62 females; median age: 19 years; range, 18 to 20 years) attending a two-year paramedic program between February 2018 and April 2018. The CKCUEST was used to determine upper extremity performance scores, including the touch number, normalized, and power score of the paramedic students. A TrueCPR® feedback device was used to measure CPR quality criteria throughout the study. The characteristics of the providers, such as height, weight, body mass index (BMI), and fat-free mass were also analyzed. Results: Adequate compression depth had a positive correlation with body fat-free mass (r=0.397, p<0.001), power score (r=0.326, p=0.001), height (r=0.326, p=0.001), weight (r=0.314, p=0.001), and BMI (r=0.204, p=0.037). Full chest recoil had a negative correlation with the power score (r=-0.249, p=0.010) and height (r=-0.219, p=0.025). None of the variables were significantly different between the groups with and without the correct compression rate. In the receiver operating characteristic curve analysis for power score and correct compression depth as 100%, the area under the curve was 0.845 (p<0.001). Conclusion: The power score combination of upper extremity functionality and the rescuer's weight is the main factor affecting chest compression depth. However, this score is negatively correlated with full chest recoil.

Accuracy of Multi-organ Point-of-Care Ultrasound for Acute Kidney Injury Etiologies.

This study investigated the diagnostic performance of point-of-care ultrasound (POCUS) for acute kidney injury (AKI) etiological subgroups in emergency department (ED) patients. Multi-organ POCUS including kidney, bladder, inferior vena cava (IVC), lung and cardiac examinations were used to identify five AKI subgroups: hypovolemia, reduced cardiac output, systemic vasodilatation and renal vasomodulation, renal and post-renal. One hundred sixty-five AKI patients were included in the study. The most diagnostic parameter in the post-renal group was the presence of any hydronephrosis, with a sensitivity of 93.3% (95% confidence interval [CI]: 68.1-99.8) and specificity of 85.9% (95% CI: 79.3-91.1). For the reduced cardiac output group, the most diagnostic parameter was IVC maximum diameter >17 mm with a sensitivity of 100% (95% CI: 83.2-100) and specificity of 70.2% (95% CI: 61.6-77.7). For the hypovolemia group, the most diagnostic parameter was IVC maximum diameter ≤17.9 mm with a sensitivity of 81.2% (95% CI: 71.2-88.8) and specificity of 56.5% (95% CI: 44-68.4). For the systemic vasodilatation and renal vasomodulation group, the most diagnostic parameter was diffuse ascites with a sensitivity of 56.3% (95% CI: 29.9-80.2) and specificity of 89.9% (95% CI: 83.8-94.2). None of the parameters were significant for the renal group. We concluded that multi-organ POCUS is of diagnostic value for AKI subgroups.

Effects of metronome use on cardiopulmonary resuscitation quality.

OBJECTIVE: Whether the use of metronome affects the quality of cardiopulmonary resuscitation (CPR) remains unclear. In this study, we investigated the effect of metronome use on CPR quality. METHODS: This was a prospective, simulation-based CPR manikin study. There were two phases: without and with metronome use. Chest compression was performed for 2 min, and three CPR quality criteria including chest compression depth, recoil, and rate were recorded with TrueCPR Feedback Device in both phases. RESULTS: In all, 102 resident physicians were included. The achievement of optimal chest compression depth and complete recoil was better with metronome use than without (83% and 77% vs. 78% and 39%, P ≤ 0.001, respectively). Optimal chest compression rate was also reached with metronome use because the range of the compression rate was closer to the normal limits than those without metronome use (110 [interquartile range (IQR) 109-113] vs. 120 [IQR 109-129], P ≤ 0.001). Of all the participants, 70.6% stated that metronome use had a positive effect on their performance during the CPR application and 66.7% stated that they wished to use the metronome in their daily practice. CONCLUSION: Using a metronome during simulation-based CPR improved the compression depth and recoil by fixing chest compression rate. We suggested that metronome should be used in CPR trainings of health-care professionals.

The real victims of the islamic feast of sacrifice: injuries related to the sacrifice.

BACKGROUND: During the Feast of Sacrifice in Muslim countries, thousands of animals are slaughtered every year. Many injuries occur during the sacrifice. Thus, the aim of this study was to determine the demographic characteristics of patients, their slaughtering experience, types of injury, and related hospital costs. METHODS: This prospective observational study was conducted in Emergency Departments (EDs) of Gazi University and Ankara Training and Research Hospital. One hundred and twenty adult patients were admitted to EDs with injuries related to the slaughter and processing of meat during two consecutive Feasts of Sacrifice. RESULTS: The average age of patients was 41.85 +/- 13.6, and 101 patients (84.2%) were male. One hundred sixteen patients (96.7%) were not professionals. Ninety-seven patients (80.8%) were admitted to EDs on the first day of the feasts. Ninety-nine injuries (82.5%) were related to cutting tools, and 21 patients (17.5%) were admitted with complaints of either falling or being harmed by animals. Fourteen patients (11.7%) with tendon lacerations, finger amputations, extremity fractures, and eye traumas were taken into surgery. Hospital costs were a median 104.76 [67.48-322.12] Turkish Liras (74.30 [47.86-228.45] USD). CONCLUSION: Proper conditions for slaughter should be provided and professionals should perform the slaughter and/or processing of the meat. EDs should be supplied both more equipment and physicians, especially on the first days of the feast.

Trends in medical students' career choice of emergency medicine: A 14-year study.

INTRODUCTION: The long-term trends of medical students' choice for emergency medicine (EM) in Turkey are unclear. With this background, we aimed to determine the change in the rate of EM preferences of students over the years. METHODS: This was a cross-sectional study originated from 6th-year medical students' feedback forms, to examine trends of EM carrier preferences between 2005 and 2018 in a tertiary care academic emergency department. There are two main questions containing "would you choose EM as a specialty?" and "why?" as open-ended questions in the form. The answers to the open-ended question were classified as six main factors, which were perception of work, lifestyle, nature of work, personal job preference, mentorship/department experiences, and income. RESULTS: During the study, 2957 forms (80.6% of 3668) were completed by 6th-year medical students. Of the students, 26.5% (n = 784) responded "yes" to the question, which was "would you choose EM as a specialty?," 6.1% (n = 181) responded "do not know," and 67.4% (n = 1992) responded "no." In 2005, 15% of students stated that they would choose EM, while this rate increased to 29% in 2018 (χ 2: 9.67; P trend = 0.003). Perception of work was the most common reason for "yes" (46.3%), "no" (46%), and "do not know" answers. CONCLUSION: The rate of EM choice of medical students doubled during the study, and approximately one in three students stated that they could choose EM as their future career in the past year. Perception of work was the main factor for choosing or rejecting to EM.

Mad honey sex: therapeutic misadventures from an ancient biological weapon.

STUDY OBJECTIVE: "Mad honey" poisoning occurs from ingestion of honey produced from grayanotoxin-containing nectar, often in the setting of use as an alternative medicine. This study is designed to assess the clinical effects, demographics, and rationale behind self-induced mad honey poisoning. METHODS: The study consisted of 2 components: a standardized chart review of the signs, symptoms, and treatment of patients with mad honey ingestion, treated in our emergency department between December 2002 and January 2008; and a cross-sectional survey of a convenience sample of beekeepers specializing in the production and distribution of mad honey. RESULTS: We identified 21 cases. Patients were overwhelmingly men (18/21) and older (mean [SD]), 55 [11] years. Local beekeepers (N=10) ranked sexual performance enhancement as the most common reason for therapeutic mad honey consumption in men aged 41 through 60 years. Symptoms began 1.0 hour (SD 0.6 hour) after ingestion and included dizziness, nausea, vomiting, and syncope. Abnormal vital signs included hypotension (mean arterial pressure 58 mm Hg [SD 13 mm Hg]) and bradycardia (mean 45 beats/min [SD 9 beats/min]). Seventeen patients had sinus bradycardia and 2 had junctional rhythm. Nine patients were treated with atropine; 1 patient received dopamine. All patients were discharged 18 to 48 hours after admission. CONCLUSION: A dietary and travel history should be included in the assessment of middle-aged men presenting with bradycardia and hypotension. A mad honey therapeutic misadventure may be the cause rather than a primary cardiac, neurologic, or metabolic disorder.

[The prevalence of seatbelt usage among university lecturers]. / Ogretim üyeleri arasinda emniyet kemeri kullanim sikligi.

BACKGROUND: We aimed to determine the ratio of seatbelt (SB) usage among professors of Faculty of Medicine (Gazi University Faculty of Medicine - GUFM). METHODS: Lecturers of GUFM were observed for five working days during their proceeding to, and entrance and exit from the parking lot, and their SB usage ratio was noted. The data were recorded according to their academic status, age and gender as well as the clinics in which they work. RESULTS: A total of 392 teaching staff (253 males [64.54%], 139 females [35.46%]) were enrolled in the study and their data were recorded. Three hundred and six lecturers (78%) were of high academic level (Professor or Associate Professor), and were over 40 years. A total of 86 teaching staff (22%) held an academic level of Assistant Professor and Instructor and were younger than 40 years. We observed that 50 lecturers (12.76%) did not have a habit of wearing a SB. Among the lecturers not regularly using a SB, 40 (80%) were men, and again, 40 lecturers (80%) were of a high academic level (Professor or Associate Professor) and over 40 years. Of the lecturers driving without a SB, 46 (92%) were employed in Clinical Sciences. Most of the lecturers (30 academicians - 65.2%) driving without a SB and on staff in Clinical Sciences were the teaching staff of the Surgical Science Departments (General Surgery, Neurosurgery, Orthopedics, Anesthesiology, etc). CONCLUSION: The SB usage rate is low in Turkey. It shows an increase with higher educational level. The ratio of SB usage habit is high amongst the lecturers (87.24%). It is noteworthy that the physicians working in surgical departments, who face post-accidental cases in their practice more often than other physicians, ignore the use of a SB.

Heterotopic pregnancy presenting with acute left chest pain.

Heterotopic pregnancy is the simultaneous existence of intrauterine and ectopic gestations. Heterotopic pregnancy is an extremely rare entity in natural cycle; however, it is increasing due to widespread use of assisted reproductive techniques. Early diagnosis and intervention are crucial in avoiding short- and long-term morbidity and mortality. Unfortunately, early diagnosis is often difficult due to the presence of intrauterine pregnancy that impedes the diagnosis and early treatment for ectopic component. Clinical symptoms are not generally helpful in diagnosis, and signs of the ectopic pregnancy usually predominate. Patients will most likely present with abdominal pain, adnexial mass, enlarged uterus, peritoneal irritation signs, and a positive pregnancy test. We present a case, admitted to the emergency department, with atypical symptoms including acute left chest pain radiating to left shoulder, at 5 weeks' gestation.

Role of C-reactive protein, D-dimer, and fibrinogen levels in the differential diagnosis of central and peripheral vertigo.

Vertigo is encountered frequently in emergency services. Researchers have explored the role of serologic markers in the differentiation of central and peripheral vertigo. The study reported here was designed to evaluate the diagnostic efficacy of serologic markers (fibrinogen, D-dimer, and C-reactive protein [CRP]) in the differential diagnosis of peripheral and central vertigo. A total of 116 patients who sought treatment for vertigo at Gazi University Hospital Adult Emergency Services during a 3-mo period were included in the study. CRP, fibrinogen, and D-dimer levels were assessed in an effort to differentiate between cases of peripheral and central vertigo. In all, 65.5% of patients (76 patients) were women. Patients younger than 50 y of age accounted for 60.3% (70 patients). The average D-dimer level for the entire group of patients was 181.9+/-132.2 microg/mL, the average CRP level, 4.2+/-8.4 mg/L, and the average fibrinogen level, 421.9+/-176.0 mg/dL. Although serum D-dimer, fibrinogen, and CRP values appeared to be higher in patients with central vertigo than in those with peripheral vertigo, no statistically significant differences were noted between the 2 groups in terms of these 3 parameters (P>.05). When 6 mg/L was used as the cutoff point for CRP and 320 mg/dL was used for fibrinogen, the numbers of patients with CRP and fibrinogen levels higher than these values were significantly higher for central vertigo than for peripheral vertigo (P<.05). The present study shows that blood D-dimer, fibrinogen, and CRP levels cannot be significant markers for the differentiation of central and peripheral vertigo.

[Subcutaneous emphysema of the face, neck and upper mediastinum following a minor maxillofacial trauma]. / Minör maksillofasiyal travma sonrasi yüz, boyun ve üst mediastene yayilan cilt alti amfizem olgusu.

Subcutaneous emphysema is the inadvertent introduction of air into tissues under the skin covering the chest wall or neck. The common causes of subcutaneous emphysema are rib fracture, parenchymal lung wound and esophageal trauma. Rarely, it occurs after oral and nasal surgery or maxillofacial trauma. We observed subcutaneous emphysema spread out from periorbital region to upper mediastinum in a patient presented to em e rgency department following minor maxillofacial trauma and admitted due to a simple fracture at his frontal maxillary wall. We present this present case to emphasize early initial management and close observation of minor facial traumas which can prevent further unexpected complications.
