ABSTRACT

OBJECTIVE:  To compare the effectiveness of early warning score systems in predicting 30-day poor outcomes in Coronavirus Disease (COVID-19) patients admitted to the emergency department. STUDY DESIGN: Descriptive study. Place and and Duration of the Study: Fatih Sultan Mehmet Education and Research Hospital, Istanbul, Turkiye, from March 2020 to March 2021. METHODOLOGY: The patients who presented to the emergency department, diagnosed with COVID-19 and tested positive for polymerase chain reaction were analysed. The study included the calculation of the rapid emergency medicine score, risk stratification in the emergency department in acutely ill older patients score, 4C mortality score, and modified early warning score for the patients. These scores were then compared in terms of their ability to predict adverse outcomes, defined as intensive care admission and/or mortality. RESULTS: During the study period, 10,281 COVID-19 patients were admitted to the emergency department. Out of them, 1,826 patients were included in the study. There were 159 (8.7%) cases with poor outcomes. The risk stratification in the emergency department in acutely ill older patients Score was the most successful in poor prognosis. CONCLUSION: Based on the findings of this study, the risk stratification in the emergency department in acutely ill older patients score demonstrated greater efficacy compared to other early warning scores in identifying patients diagnosed with COVID-19 who had an early indication of a poor prognosis. KEY WORDS: Early warning score, 4C mortality score, REMS, Rise-up score, MEWS, Emergency department, COVID-19.

ABSTRACT

OBJECTIVE: Hypoxia is a frequently reported complication during the intubation procedure in the emergency department (ED) and may cause bad outcomes. Therefore, oxygenation plays an important role in emergency airway management. The efficacy of oxygenation with high-flow nasal cannula (HFNC) in the ED has been studied, though the evidence is limited. The study aim was to compare two methods of preoxygenation in patients undergoing rapid sequence intubation (RSI) in the ED: (1) HFNC and (2) bag-valve mask (BVM) oxygenation. METHODS: This is a single-center, prospective, randomized controlled trial (RCT) in adult ED patients requiring RSI. Patients were randomized to receive preoxygenation with either HFNC or BVM. While HFNC therapy was continued during the intubation procedure, BVM oxygenation was interrupted for laryngoscopy. The primary outcome was the lowest peripheral oxygen saturation (SpO2) level during intubation. Secondary outcomes were incidence of desaturation (SpO2<90%) and severe hypoxemia (SpO2<80%) throughout the procedure, intubation time, rate of failed intubation, and 30-day survival rates. RESULTS: A total of 135 patients were randomized into two groups (HFNC n = 68; BVM n = 67). The median lowest SpO2 value measured during intubation was 96% (88.8%-99.0%) in the HFNC group and 92% (86.0%-97.5%) in the BVM group (P = .161). During the intubation procedure, severe hypoxemia occurred in 13.2% (n = 9) of patients in the HFNC group and 8.9% (n = 6) in the BVM group, while mild hypoxemia was observed in 35.8% (n = 24) of the BVM group and 26.5% (n = 18) of the HFNC group. However, there was no statistically significant difference between the groups in terms of hypoxemia development (P = .429 and P = .241, respectively). No significant difference was reported in the rate of failed intubation between the groups. Thirty-day mortality was observed in 73.1% of the BVM group and 57.4% of the HFNC group, with a borderline statistically significant difference (difference 15.7; 95% CI of the difference: -0.4 to 30.7; P = .054). CONCLUSION: The use of HFNC for preoxygenation, when compared to standard care with BVM oxygenation, did not improve the lowest SpO2 levels during intubation. Also, the use of HFNC during intubation did not provide benefits in reducing the incidence of severe hypoxemia. However, the 30-day survival rates were slightly better in the HFNC group compared to the BVM group.

ABSTRACT

Background Aim of this study is to investigate whether end-tidal carbon dioxide (ETCO 2 ) values can be used instead of partial pressure of carbon dioxide (PaCO 2 ) values in guiding treatment, and determining treatment benefits in patients that received a pre-diagnosis of chronic obstructive pulmonary disease (COPD) exacerbation at the emergency department. Methods This observational prospective study was conducted with patients who presented to the emergency department with the complaint of shortness of breath and were diagnosed with COPD exacerbation. ETCO 2 was measured with the sidestream method during blood gas analysis in patients with indications for this analysis. Measurements were repeated at hour 1 after treatment. Results The study included a total of 121 cases. There was a positive correlation between the PaCO 2 and ETCO 2 values measured before and after treatment ( r = 0.736, p < 0.01 and r = 0.883, p < 0.01, respectively). High ETCO 2 values were accompanied by high PaCO 2 values. When the measurements before and after treatment were evaluated using the Bland-Altman method, most of the result were within the limits of agreement (-4.9 and +31.4/- 2.6 and +9.4), with mean differences being calculated as 13.2 and 8.4, respectively. Conclusions Although ETCO 2 and PaCO 2 were statistically consistent according to the results of our study, due to the high averages of differences between these two parameters, the ETCO 2 value has limited clinical use in COPD cases compared to PaCO 2 . However, high ETCO 2 values may indicate that noninvasive mechanical ventilation should be included in the treatment of COPD cases without waiting for the results of blood gas analysis, and they can also be when needed for inpatient treatment.

ABSTRACT

It is important to do a fast and effective treatment for patients with renal colic pain in emergency departments for both patients' comfort and clinicians' patient management. In this study, we aimed primarily to test the efficacy of intradermal sterile water application as a rapid and effective treatment in severe renal colic. This is a single-centre, prospective, randomised controlled trial. Study group consists of patients with severe renal colic related to urolithiasis. Patients were randomly divided into three groups. The first group received only intramuscular diclofenac sodium, the second group received intramuscular diclofenac sodium and intradermal sterile water, and the third group received intramuscular diclofenac sodium together with intravenous fentanyl. Numerical Rating Scale was used to determine the level of pain before and after the treatment at the 1st, 5th, 15th, 30th, 60th and 120th minutes. 95 out of 201 patients with severe renal colic pain randomly divided into 3 groups. The pre-treatment pain severity of the groups was similar (p = 0.228). We found that the decrease in pain intensity was significantly faster in the intradermal sterile water group than the other groups even in the first minute. Percentages of patients who had 50% pain reduction, which is considered as successful treatment, was higher in the intradermal sterile water group (which had 75.9% success rate) in the first 5 min compared to the IM diclofenac sodium group (which had 7.1% success rate) and IV fentanyl group (which had 25% success rate) (p < 0.001). According to the results, pain control was achieved much faster than the other methods with intradermal sterile water injection. All methods were found to be effective in relieving the pain of the patients.

ABSTRACT

The treatment options are limited in Acinetobacter baumannii infections. In this study, the effectiveness of colistin monotherapy and combinations of colistin with different antibiotics were investigated in an experimental pneumonia model induced by carbapenem-resistant A. baumannii strain. Mice in the study were divided into five groups as control (no treatment), colistin monotherapy, colistin + sulbactam, colistin + imipenem, and colistin + tigecycline combinations. The modified experimental surgical pneumonia model of Esposito and Pennington was applied to all groups. The presence of bacteria in blood and lung samples was investigated. Results were compared. In blood cultures, while there was no difference between the control and colistin groups, there was a statistical difference between the control and the combination groups (P = 0.029). When the groups were compared in terms of lung tissue culture positivity, there was a statistical difference between the control group and all treatment groups (colistin, colistin + sulbactam, colistin + imipenem, and colistin + tigecycline) (P = 0.026, P < 0.001, P < 0.001, and P = 0.002, respectively). The number of microorganisms that grew in the lung tissue was found to be statistically significantly lower in all treatment groups in comparison with the control group (P = 0.001). Both monotherapy and combination therapies of colistin were found to be effective in the treatment of carbapenem-resistant A. baumannii pneumonia, but the superiority of combination therapies over colistin monotherapy has not been demonstrated.

ABSTRACT

BACKGROUND: Appropriate triage is an important component of patient management in emergency departments. The risk scoring system used for triage purposes in emergency departments should be obtained quickly and based on parameters directly related to prognosis. AIMS: To investigate the success of the Rapid Emergency Medicine Score (REMS) and Rapid Acute Physiology Score (RAPS) as triage scoring systems and the Mortality Probability Model (MPM II0) as an intensive care scoring system in identifying critical patients visited to the emergency department (ED) triage and predicting mortality, and to evaluate their superiority over each other, if any. METHODS: This research was planned as a single-center and prospectively. The data of the study were obtained by screening the medical records of all patients who presented to the ED triage between January 1, 2020 and January 31, 2020. Patients under the age of 18 years, those with missing information in their files and pregnant women were not included in the study. Only the patients for whom the REMS, RAPS, and MPM II0 scores could be calculated were included in the sample. RESULTS: After excluding the patients who did not meet the inclusion criteria, the study was completed with 12,210 patients. The mean age of these patients was 44.7 ± 18.7 years, and 47.3% were male. The area under the receiver operating characteristics curve values for the prediction of 24-h, 30-day, 90-day, and 180-day mortality were determined as 0.979, 0.921, 0.904, and 0.897, respectively, for REMS; 0.929, 0.778, 0.75, and 0.725, respectively, for RAPS; and 0.925, 0.888, 0.866, and 0.861, respectively, for MPM II0. CONCLUSIONS: In this study, it was concluded that the REMS score was superior to the MPM II0 and RAPS scores in predicting the short-term and long-term mortality status of patients and determining the discharge and hospitalization status of the patients.

ABSTRACT

INTRODUCTION: The COVID-19 disease has given rise to various negative effects on human life in terms of health and economic and social well-being. We believe that these negative effects may have led to increased forensic incidents such as violence and suicide. Therefore, in this study, we sought to examine the effects of COVID-19 in forensic cases admitted to an emergency department. Methods: This is a retrospective observational study, performed at the emergency department of Fatih Sultan Mehmet Education and Research Hospital. Forensic cases admitted between March and June 2020 (pandemic period) and forensic cases admitted between March and June 2019 (pre-pandemic period) were compared in the study. Results: A total of 4296 patients were included in the study, of which 3011 were admitted during the pre-pandemic period and 1285 during the time of the COVID-19 pandemic. While the percentages of suicide attempts (3.6%), motorcycle traffic accidents (7.4%), and violent incidents (29.4%) were higher during the pandemic period, the percentages of in-vehicle traffic accidents (5.4%) and pedestrian traffic accidents (2.2%) were lower (respectively, p = 0.035, p = 0.005, p < 0.001, p = 0.015, p = 0.008). At the time of the pandemic, the percentages of incidents of violence against women (44.2%) and traffic accidents with a motorcycle involving men (9.3%) were higher than during the time before the pandemic (p < 0.001 and p < 0.001, respectively). Conclusions: The effects of the pandemic on our lifestyle are indisputable. This study reveals that the pandemic also affected patients who were admitted to the emergency department for forensic reasons. In addition, the increase in the percentages of suicide and violent events indicates that pandemics probably increase feelings of fear, loss, and hopelessness, and special precautions should be taken to maintain order in the society.

ABSTRACT

BACKGROUND: Colorectal cancer is one of the most commonly diagnosed types of cancer worldwide. An early diagnosis and detection of colon cancer and polyp can reduce mortality and morbidity from colorectal cancer. Even though there are a variety of options in screen- ing tests, the question remains on which test is the most effective for the early detection of colorectal cancer. In this prospective study, we aimed to develop a simple, useful, effective, and reliable scoring system to detect colon polyp and colorectal cancer. METHODS: We enrolled 6508 subjects over the age of 18 from 16 centers, with colonoscopy screening. The age, smoking status, alcohol consumption, body mass index, polyp incidence, polyp size, number and localization, and pathologic findings were recorded. RESULTS: The age, male gender, obesity, smoking, and family history were found as independent risk factors for adenomatous polyp. We have developed a new scoring system which can be used for these factors. With a score of 4 or above, we found the following: sensitivity 81%, specificity 40%, positive predictive value 25.68%, and negative predictive value 89.84%, for adenomatous polyp detection; and sensitivity 96%, specificity 39%, positive predictive value 3.35%, negative predictive value 99.29%, for colorectal cancer detection. CONCLUSION: Even though the first colorectal cancer screening worldwide is generally performed for individuals over 50 years of age, we recommend that screening for colorectal cancer might begin for those under 50 years of age as well. Individuals with a score ≥ 4 must be included in the screening tests for colorectal cancer.

ABSTRACT

PURPOSE: Non-contrast computed tomography (ncCT) is the first-line imaging modality for acute ischaemic stroke diagnosis. Recognition of the early diagnostic signs of a stroke on computed tomography (CT) is crucial. The hyperdense middle cerebral artery (MCA) sign is one of these findings. We investigated the diagnostic utility of absolute MCA density (MCAD) in patients with acute MCA stroke confirmed with diffusion-weighted magnetic resonance imaging (dwMRI). METHODS: We retrospectively included all patients who presented to the Emergency Department with symptoms related to an acute stroke and confirmed with a dwMRI and ncCT to this diagnostic case-control study. An expert radiologist with more than four years of experience in neuroradiology re-evaluated all ncCT images. The evaluation of MCAD and ratio were measured on axial images in Hounsfield units (HU). RESULTS: We included 407 patients in our study (MCA infarction: 55%, n = 225; Control: 45%, n = 182). We calculated the threshold for the highest sensitivity (20%) and specificity (94%) as 49 HU with the Youden J index test for MCAD and as 1.1 for MCAD ratio (sensitivity 20% and specificity 95%). MCAD >49 HU or MCAD ratio >1.1 alone or joint use of MCAD >47 HU and MCAD ratio >1.1 are useful markers to confirm the diagnosis of MCA AIS with a specificity of at least 94%. Higher MCAD values are associated with larger infarction volumes. CONCLUSION: MCAD and MCAD ratio can be used to identify patients who need early treatment, especially in situations where computed tomography angiogram or dwMRI are not readily available.

ABSTRACT

BACKGROUND: Assessment of the respiratory changes of the inferior vena cava (IVC) diameter have been investigated as a reliable tool to estimate the volume status in mechanically ventilated and spontaneously breathing patients. Our purpose was to compare the echocardiographic measurements the IVC diameter, stroke volume and cardiac output in different positive pressure ventilation parameters. METHODS: This prospective clinical study with crossover design was conducted in the Intensive Care Unit (ICU). Twenty-five sedated, paralyzed, intubated, and mechanically ventilated patients with volume control mode (CMV) in the ICU due to respiratory failure were included in the study. Positive End-Expiratory Pressure (PEEP) and Tidal Volume (TV) were changed in each patient consecutively (Group A: TV 6 ml/kg, PEEP 5 cmH20, B: TV 6, PEEP 8, C: TV 8, PEEP 5, D: TV 8, PEEP 8) and the changes in vital parameters, central venous pressure (CVP) and ultrasonographic changes in IVC and cardiac parameters were measured. All measures were compared between groups by robust repeated measures ANOVA with trimmed mean. RESULTS: The respiratory changes of the IVC diameter and echocardiographic parameters showed no significant difference in separate mechanical ventilator settings. Significant difference was found in peak and plateau pressure values among groups (p < 0.05). CONCLUSION: The results of our study suggest that IVC related parameters are not affected with different ventilatory settings. Further studies are needed to confirm the reliability of these parameters as a predictor of fluid assessment.

ABSTRACT

OBJECTIVE: Our study was carried out on patients admitted to the emergency ward with acute stroke symptoms that were subsequently diagnosed with cerebrovascular disease. We aimed to examine the relationship between these patients' admission lactate levels and their 1-, 3-, and 12-month mortality rates in order to evaluate the prognostic value of lactate levels. METHODS: Our data were obtained retrospectively from 568 patients diagnosed with acute ischemic stroke at our emergency department between 1 January 2017 and 1 January 2018. Patient data were accessed via the hospital patient database. Included patients' files were assessed for examination and history taken at admission, comorbid diseases, demographic characteristics, treatments utilized, and laboratory results. Hyperlactatemia was defined as a lactate level of over 2 mmol/L. The relationship between lactate levels and survival was investigated. Patients' complication rates after discharge were assessed alongside their 1-, 3-, and 12-month mortality. RESULTS: Our study assessed 568 patients. Out of these patients, 400 patients met our inclusion criteria and constituted the study population. These patients were separated into two groups according to their lactate levels. The hyperlactatemic group had a statistically significant increase in 1-, 3-, and 12-month mortality rates in comparison to the other group. CONCLUSIONS: Our study found that hyperlactatemia was associated with a higher risk of 1-, 3-, and 12-month mortality, suggesting that it has predictive prognostic value. In the future, we believe that prospective observational studies and/or large-scale retrospective studies will be of great value in providing more insight into this topic.

ABSTRACT

OBJECTIVE: Head trauma is one of the most important emergency health problems both in the world and in our country. The objective in our study is to (i) state the correlation between the findings of bispectral index score (BIS) and computed tomography (CT), which are used to evaluate the level of consciousness of patients with isolated head trauma, and (ii) investigate objective results about the patient's level of consiousness/alertness according to the CT modality, which is used frequently. METHODS: This prospective study was carried out between 03.01.2014 and 09.01.2014 in the emergency department of Fatih Sultan Mehmet Education and Research Hospital. The average BIS scores were correlated with the Glasgow Coma Scale (GCS) point, the Canadian CT Head Rule major and minor criteria, and the pathologic findings in CT imaging. The patients' demographic features, vital signs at admission, and arrival times at the hospital were investigated. RESULTS: In our study, 64 (31.7%) patients were female, and 138 (68.3%) patients were male. The mean BIS scores were 84.99±11.20 (86.05) and 93.78±3.80 (95.05) in patients with and without CT pathologies, respectively. The correlation between CT pathology and BIS scores was statistically significant: BIS scores were lower in patients with CT pathologies (p=0.001; p<0.01). There was a statistically significant positive correlation between the BIS and GCS scores (45.6%) (p<0.05). CONCLUSION: We showed that most head traumas occur after dangerous accidents, and according to the results, we can predict that males are more frequently affected than females. There was a statistically significant positive correlation between BIS scores and GCS points. In our study, the BIS scores were statistically significantly lower in patients with CT pathology than in patients without. We can predict that if the BIS score of the patient is low, then there will be the presence of pathology on CT imaging.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the prevalence of Pediculus humanus (P.h.) capitis infestation in school children in Sücüllü Village, Isparta. METHODS: The study was conducted from April to May 2016 in Sücüllü Village. Hair of 204 students were examined for eggs, nymphs, and adults of P.h. capitis. Data regarding age, sex, family's type of living were recorded for each child. RESULTS: It was found that 9.3%of students were infested by P.h capitis. The prevalence of infestation was significantly higher in girls (17.4%) than in boys (p<0.05). School children in the age group of 8-9 years exhibited higher prevalence rates. Infestation rate was also high in livestock families (p<0.05). CONCLUSION: This study revealed that socioeconomic status is a major factor that influences the occurence of pediculosis among students of both sexes in Isparta. Infestation is more common in crowded families.

ABSTRACT

Although the mechanism of action is not well known, intravenous lipid emulsion (ILE) has been shown to be effective in the treatment of lipophilic drug intoxications. It is thought that, ILE probably separates the lipophilic drugs from target tissue by creating a lipid-rich compartment in the plasma. The second theory is that ILE provides energy to myocardium with high-dose free fatty acids activating the voltage-gated calcium channels in the myocytes. In this study, effects of ILE treatment on digoxin overdose were searched in an animal model in terms of cardiac side effects and survival. Forty Sprague-Dawley rats were divided into five groups. As the pre-treatment, the groups were administered saline, ILE, DigiFab and DigiFab and ILE. Following that, digoxin was infused to all groups until death except the control group. First arrhythmia and cardiac arrest observation times were recorded. According to the results, there was no statistically significant difference among the group in terms of first arrhythmia time and cardiac arrest times. However, when the saline group compared with ILE-treated group separately, significant difference was observed. DigiFab, ILE or ILE-DigiFab treatment make no significant difference in terms of the first arrhythmia and cardiac arrest duration in digoxin-intoxicated rats. However, it is not possible to say that at the given doses, ILE treatment might be successful at least as a known antidote. The fact that the statistical significance between the two groups is not observed in the subgroup analysis, the study should be repeated with larger groups.

ABSTRACT

INTRODUCTION: Vertigo is classified as peripheral and central. Differentiation of stroke mimics is the most important diagnostic challenge. There is no clinical guidance for the indications of neuroimaging in isolated vertigo patients. The primary aim of this study is to test the diagnostic value of a DWI-MRI protocol to rule-out a central cause in patients with acute isolated vertigo in the ED. METHODS: We prospectively enrolled 144 patients who were presented with isolated vertigo to the ED. A detailed neurological examination and maneuvers were performed for differential diagnosis. All patients underwent CT and/or DW-MRI either during ED visit or at the follow-up, if necessary. Out-patient follow-up exams and evaluations were repeated until all patients had a definitive diagnosis. RESULTS: In the study, 137 of the 144 patients completed the follow-up period, and 34 of 137 patients were diagnosed with central vertigo. Six of 34 central vertigo patients had normal DW-MRI findings. One was diagnosed with migraine headache and five with vertebra-basilar insufficiency during the out-patient follow-up. One of the 28 patients with a pathological MRI was diagnosed with mass and the rest was stroke. The utility of DW-MRI in vertigo patients was moderately high (sensitivity: 82%, specificity: 100%). We found that age, history of HT, history of CAD and vertigo unresponsive to ED treatment were significantly associated with a central cause of vertigo. CONCLUSION: We suggest that unresponsiveness to ED treatment, especially in patients with a history of HT and CAD, should alert physicians for central causes and warrant DW-MRI imaging.

ABSTRACT

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.

ABSTRACT

This study aimed to determine the antimicrobial efficacy of NaOCl, cetrimide, and Glycyrrhiza glabra L. extract against Enterococcus faecalis biofilms on dentine discs. Broth microdilution method was used to determine minimal bactericidal concentrations (MBCs) of the agents. A biofilm susceptibility assay was performed using E. faecalis biofilms grown on dentine discs. Minimal bactericidal concentrations (MBCs) of NaOCl (0.5%), cetrimide (0.015%), and G. glabra L. extract (0.25%) were applied for 1, 3, and 5 min, and the mean viable cell counts were recorded and statistically analyzed. There was no significant difference between cetrimide and NaOCl at 1 min (p>0.05). NaOCl was the most effective agent at 3 and 5 min (p<0.05) while G. glabra L. extract was the least (p<0.05). The MBCs of NaOCl, cetrimide, and G. glabra that eliminated the planktonic E. faecalis did not eradicate the biofilms grown on dentin discs.

ABSTRACT

Diagnosis and measuring the level of increase in intracranial pressure (ICP) is critical, especially for the management of trauma patients in the emergency department and intensive care unit. However, measurements are operator-dependent as in all of the sonographic diagnoses. The aim of this study is to assess the operator variations in the measurement of optic nerve sheath diameter (ONSD). There were four emergency medicine specialists involved in the study. Each had at least 1 year of experience of ultrasound scans and performed at least 25 prior ocular scans examining the ONSD. Two measurements were made 1 week apart from both axial and longitudinal planes. Sixty healthy adults were involved in the study and every investigator obtained four measurements from each. Intra-interobserver reliabilities were tested. The investigators performed 60 ocular ultrasounds on individual healthy adults and obtained two measurements in axial and longitudinal planes 1 week apart. Therefore, 960 measurements were analyzed. The levels of compatibilities for most of the measurements were found at acceptable levels statistically. However, it is not possible to say that there was a perfect compatibility among the sonographers according to the previously conducted reliability studies of ultrasound measurements. According to our results, it is hard to say that sonographic measurement of the ONSD is a highly reliable method both in longitudinal and transverse planes.

ABSTRACT

Optic neuropathy due to cat scratch disease (CSD) is a rare occurrence associated with macular star formation and is characterised by sudden mostly unilateral painless loss of vision. The aetiological agent in CSD is Bartonella henselae. Ocular complications present in up to 10% of patients and include neuroretinitis, conjunctivitis or uveitis. Ocular bartonelosis is usually self-limited. A case of a man patient with neuroretinitis caused by B. henselae is reported.
