RESUMEN
Annually, 172 million fall events cause temporary or permanent impairment in older adults, and this number is increasing. Contributing factors that increase the risk for falls include age, polypharmacy, and malnutrition. This study evaluated medications mainly included in the EU(7)-PIM (potentially inappropriate medication) list. From March 21, 2022, to July 6, 2022, 945 patients who experienced a fall and visited the Department of Emergency Medicine at the Albert Szent-Györgyi Health Centre of the University of Szeged in Hungary. Data from 886 patients were collected (study group). The control group included 1364 patient data collected from three general practice in Hungary. The use of ≥ 2 EU(7)-PIM drugs was found to be associated with increased risk for falls (adjusted odds ratio [AOR], 1.38; 95% confidence interval [CI] 1.01-1.88). Piracetam (AOR, 1.81; 95% CI, 1.28-2.57) and trimetazidine (AOR, 1.62; 95% CI, 1.17-2.24) were associated with increased risk for falls. Doxazosin was associated with a low risk for falls (AOR, 0.59; 95% CI, 0.41-0.86). Tiapride (AOR, 3.54; 95% CI, 1.75-7.17), gliclazide (AOR, 1.57; 95% CI, 1.02-2.43), and vinpocetine (AOR, 1.95; 95% CI, 1.29-2.95) are not included in the EU(7)-PIM list; however, they are associated with increased risk for falls. Long-acting benzodiazepines (AOR, 1.79; 95% CI, 1.20-2.68), antidepressants (AOR, 1.89; 95% 95% CI, 1.37-2.61), serotonin-norepinephrine reuptake inhibitor (AOR, 2.82; 95% CI, 1.41-5.67; p < 0.01), and selective serotonin reuptake inhibitor (AOR, 1.88; 95% CI, 1.24-2.85) were also associated with increased risk for falls. However, Z-drugs were associated with a low risk for falls (AOR, 0.57; 95% CI, 0.36-0.92). With the help of this tool, trimetazidine and piracetam are filtered as EU(7)-PIM drugs associated with increased risk for falls.
RESUMEN
Purpose: Favipiravir has been used in the therapy of COVID-19, including patients with mild to moderate symptoms in certain countries. The aim of our systematic review and meta-analysis was to investigate its efficacy and safety in mild-to-moderate COVID-19 infections. Methods: The PubMed, Embase, Web of Science, and Cochrane databases were systematically reviewed for articles reporting the results of randomized controlled trials published until January 6, 2023, resulting in the identification of 20 eligible studies. Results: There were no significant differences in viral clearance time (HR = 1.20, p = 0.09) compared to those without favipiravir therapy. However, in the subgroup analyses, favipiravir treatment significantly increased viral clearance by 59 % (HR = 1.59, p < 0.01) and 42 % (HR = 1.42, p < 0.01], I2 = 20 %) compared to the comparator group in patients with moderate severity of COVID-19 and in the inpatient care setting, respectively. Favipiravir had no beneficial effects in the case of patients with mild symptoms and treated in ambulatory care. Conclusions: The use of favipiravir is questionable in the treatment of outpatients with COVID-19 with mild symptoms. Moderate beneficial effects in the case of patients with moderate symptoms and inpatients should be treated with care due to the limitations of the analysed trials.
RESUMEN
Extensive use of carbapenems may lead to selection pressure for Stenotrophomonas maltophilia (SM) in hospital environments. The aim of our study was to assess the possible association between systemic antibiotic use and the incidence of SM. A retrospective, observational study was carried out in a tertiary-care hospital in Hungary, between January 1st 2010 and December 31st 2019. Incidence-density for SM and SM resistant to trimethoprim-sulfamethoxazole (SXT) was standardized for 1000 patient-days, while systemic antibiotic use was expressed as defined daily doses (DDDs) per 100 patient-days. Mean incidence density for SM infections was 0.42/1000 patient-days; 11.08% were were resistant to SXT, the mean incidence density for SXT-resistant SM was 0.047/1000 patient-days. Consumption rate for colistin, glycopeptides and carbapenems increased by 258.82, 278.94 and 372.72% from 2010 to 2019, respectively. Strong and significant positive correlations were observed with the consumption of carbapenems (r: 0.8759; P < 0.001 and r: 0.8968; P < 0.001), SXT (r: 0.7552; P = 0.011 and r: 0.7004; P = 0.024), and glycopeptides (r: 0.7542; P = 0.012 and r: 0.8138; P < 0.001) with SM and SXT-resistant SM incidence-density/1000 patient-days, respectively. Implementation of institutional carbapenem-sparing strategies are critical in preserving these life-saving drugs, and may affect the microbial spectrum of infections in clinical settings.
RESUMEN
BACKGROUND: Burnout is still one of the leading mental health problems. According to research results over the past decades, healthcare workers, including paramedics, are considered a high-risk group. In concordance with these results, the available resources need to prioritize monitoring paramedics' mental health. METHODS: In our study, we investigated whether the available test batteries measuring burnout could be reduced while maintaining their effectiveness. We reduced the 21-item Burnout Measurement and the 8-item version of the Psychosomatic Symptom Scale using the data of 727 Hungarian paramedics. We selected the top four items of the questionnaires that were significantly correlated with the original Burnout Measure Index and the Psychosomatic Scale Index. The classification efficiency of the shortened list of items was based on the initial risk categories of the Burnout Measure and its sensitivity was analyzed using Binary Logistic regression and ROC curves. We then used Two-Step Cluster Analysis to test the ability of the shortened Burnout Measure Index to develop new risk categories. The reliability indicators were also explored. RESULTS: The results show that the Burnout Measurement can be reduced to 4 items with a classification efficiency of 93.5% in determining the level of burnout. The 5-item reduction of the Psychosomatic Symptom Scale can classify subjects to the appropriate intervention level for burnout with an efficiency of 81.6%. The ROC analysis suggests that the shortened questionnaires have an excellent separative ability to discriminate between the initial risk groups. Three new risk categories were also identified as a result of the cluster analysis. CONCLUSION: The shortened scales may be proven effective in resource management, which could significantly quicken the assessment of burnout in the future. The abbreviated scale is also suitable for classifying subjects into risk categories. However, further research is needed to see whether the shortened scales can be used as a diagnostic tool.

INTRODUCTION: The aim of our prospective study was to confirm validity and diagnostic accuracy of the modified Alvarado score, which was developed at the Department of Surgery, University of Szeged, on patients presenting with symptoms suggestive of acute appendicitis (right lower quadrant complaints) at the A&E department. PATIENT POPULATION, METHODS: 138 patients were included in our study between 01.01.2019 and 01.01.2020. For patients attending A&E, the first medic calculated and recorded the modified Alvarado score before surgical consultation. The consulting surgeon decided on further treatment without knowing the score. Validation of the score was based on the pathology report of the removed appendix (whether the operation was warranted, and if the score also supported indication for surgery), if there was readmission or surgery due to worsening symptoms after discharge from A&E. We also examined if there was any connection between the value of the Alvarado score and the severity of inflammation. Our aim was to prove that using modified Alvarado score at the A&E Units helps to reduce patient's waiting time and avoid unnecessary surgical consultations. Furthermore our study included measuring the diagnostic accuracy of the ultrasound examination (specificity, sensitivity). RESULTS: Based on the results, patients presenting at A&E had a mean modified Alvarado score of 6.5. Comparing the score to histological results showed that the specificity of the modified Alvarado score was 100%, and its sensitivity was 80.7%. Based on Spearman's rank correlation (0.796) and ROC analysis (AUC 0.968), the modified Alvarado score has an excellent predictive value in diagnosing acute appendicitis. When comparing the patients' waiting times with the use of modified Alvarado score and without it we found that there was a significant difference in group also in group under 4 points and in group over 7 points when using modified Alvarado score, so the diagnostic and therapeutic algorithm should be much quicker with the help of the score. We found a correlation between the severity of inflammation based on the Fisher's exact test. Rank correlation of the same question also showed a significant connection. All patients had an US examination during their diagnostic course, its sensitivity was 82.6%, specificity was 87%. Based on this, we can conclude that the predictive value of the imaging method is good. CONCLUSIONS: We can conclude according to our results that the predictive value of the modified score is excellent, and it can be safely applied by non-surgeons in urgent care in the differential diagnosis of acute appendicitis. The new score incorporates the results of an easily obtainable, ionising radiation free imaging method, the ultrasound, which was not included in previous scores. With the help of the new score, the number of unnecessary surgical referrals and waiting times for patients are reduced, excess examinations will become avoidable.

BackgroundIn 2019, the World Health Organization published the 21st Model list of Essential Medicines and updated the Access, Watch Reserve (AWaRe) antibiotics classification to improve metrics and indicators for antibiotic stewardship activities. Reserve antibiotics are regarded as last-resort treatment options.AimWe investigated hospital-sector consumption quantities and trends of Reserve group antibiotics in European Union/European Economic Area countries and the United Kingdom (EU/EEA/UK).MethodsHospital-sector antimicrobial consumption data for 2010-2018 were obtained from the European Centre for Disease Prevention and Control. Antibacterials' consumption for systemic use (Anatomical Therapeutic Chemical classification (ATC) group J01) were included in the analysis and expressed as defined daily doses (DDD) per 1,000 inhabitants per day. We defined reserve antibiotics as per AWaRe classification and applied linear regression to analyse trends in consumption of reserve antibiotics throughout the study period.ResultsEU/EEA/UK average hospital-sector reserve-antibiotic consumption increased from 0.017 to 0.050 DDD per 1,000 inhabitants per day over the study period (p = 0.002). This significant increase concerned 15 countries. In 2018, four antibiotics (tigecycline, colistin, linezolid and daptomycin) constituted 91% of the consumption. Both absolute and relative (% of total hospital sector) consumption of reserve antibiotics varied considerably (up to 42-fold) between countries (from 0.004 to 0.155 DDD per 1,000 inhabitants per day and from 0.2% to 9.3%, respectively).ConclusionAn increasing trend in reserve antibiotic consumption was found in Europe. The substantial variation between countries may reflect the burden of infection with multidrug-resistant bacteria. Our results could guide national actions or optimisation of reserve antibiotic use.

BACKGROUND: Burnout and psychological immune competency have not been investigated together among employees of high-risk specializations such as emergency medicine, intensive care or surgery. AIM: In this study we aim to examine the prevalence of burnout among high-risk clinical staff and explore whether the strength of psychological immune competency predict burnout. DESIGN: A cross-sectional design utilizing a self-administrated questionnaire was used to collect data from the participants (n = 216). Nurses (n = 145) and physicians (n = 71) from emergency medicine, intensive care and surgery departments participated in the study. METHOD: Burnout syndrome was measured using the Maslach Burnout Inventory, while psychological immune competency was measured using the Psychological Immune Competency Questionnaire. The data collection started in June of 2018 and was finished in March of 2019. RESULTS: Participants with higher psychological immune competency reported lower levels of burnout: emotional exhaustion (r = -0.478; p < 0.001), depersonalization (r = -0.459; p < 0.001) and personal accomplishment (r = 0.543; p < 0.001). Multiple linear stepwise regression analysis revealed the psychological immune competency to be a stable predictor of burnout on all three scales. CONCLUSION: Psychological immune competency shows a strong relationship with scales of burnout syndrome and as such should be further examined due to development of successful intervention and prevention programs.

BACKGROUND: COVID-19 pandemic has had a global major healthcare, social and economic impact. In present study we aim to adapt the Fear of COVID-19 Scale to Hungarian. MATERIALS AND METHODS: Forward-backward translation method was used to translate the English version of the scale to Hungarian. Participants were a convenience sample of 2175 university students and employees. The study was conducted between January 18th and February 12th 2021. The test battery included Hungarian versions of Fear of COVID-19 scale, short Beck Depression Inventory (BDI-H) and State-Trait Anxiety Inventory (STAI). RESULTS: The scale showed one-factor structure, the loadings on the factor were significant and strong (from .47 to .84). Internal consistency was very good (α = .84). Construct validity for the Fear of COVID-19 Scale was supported by significant and positive correlations with STAI (r = 0.402; p < 0.001) and BDI-H (r = 0.270; p < 0.001). CONCLUSION: The Hungarian version of Fear of COVID-19 Scale is a reliable and valid tool in assessing fear of coronavirus.

Antibiotic treatments initiated on Emergency Departments (ED) are empirical. Therefore, knowledge of local susceptibility patterns is important. Despite this, data on expected pathogens and their resistance profile are scarce from EDs internationally. The study aim was to assess the epidemiology and resistance patterns of bacterial isolates from a tertiary-care ED over 5 years, focusing on ESKAPE bacteria (including the Enterobacterales group). After removal of duplicates, n = 6887 individual bacterial isolates were recovered, out of which n = 4974 (72.22%) were ESKAPE isolates. E. coli was the most frequent isolate (2193, 44.1%), followed by the Klebsiella genus (664; 13.4%). The third most frequent isolate was S. aureus (561, 11.3%). In total, multi-drug resistance (MDR) was present in 23.8% and was most prevalent in A. baumanii (65.5%), P. mirabilis (42.7%), and K. pneumoniae (32.6%). MRSA was isolated in 19.6%, while ESBL-producing Enterobacterales in 17.7%, and these were associated with remarkably higher resistance to other antibacterials as well. Difficult-to-treat resistance (DTR) was detected in 0.5%. The frequent isolation of some ESKAPE bacteria and the detected considerable acquired resistance among ED patients raise concern. The revealed data identified problematic pathogens and will guide us to set up the optimal empiric antibiotic protocol for clinicians.
RESUMEN
Solobacterium moorei is a strict anaerobic gram-positive rod. It is found in the human microbiota in different parts of the body, but it also appears to be an opportunistic pathogen in some infectious processes. We describe six cases of severe infections identified in 2016 in which S. moorei was isolated alone or in mixed culture involving other anaerobes or both aerobic and anaerobic bacteria. Three cases were associated with the oral cavity, including a middle ear infection, a wound infection after total laryngectomy, and a mandibular abscess as a result of bisphosphonate therapy. In the other three patients, the sites of infection had no connections with the oral cavity and included chronic osteomyelitis of the tibia, a superinfection of cutaneous tuberculosis associated with hidradenitis suppurativa, and the isolation of S. moorei from the blood culture of a cachectic man with several comorbidities. Based on our findings, S. moorei does not appear to be that virulent of a bacterium; except for the case with bacteraemia, S. moorei was recovered as a co-pathogen in patients with several immunosuppressive predisposing factors. We highlight the finding that the routine use of MALDI-TOF MS in microbiology laboratories can in a timely and detailed manner identify members of mixed infections involving different anaerobic bacteria that may be rare and difficult-to-culture and identify species, such as S. moorei.

Antenatal and postpartum depression has been associated with maternal, child and family-unit complications. Our aim was to assess the impact of a depression screening and intervention program on perinatal complications. This study included 2042 women. They were screened on the Edinburgh Postnatal Depression Scale (EPDS), three times during pregnancy and once after childbirth. If their EPDS score was above the cut-off score, psychological intervention was offered. Significant relationships were found between depression scores and perinatal complications, such as protracted cervical dilation, protracted descent, preeclampsia, intrauterine growth restriction, low birthweight and cesarean section. Depression scores were higher in the intervention group, compared to the non-intervention group, but decreased after the consultations. The cesarean section rate was significantly lower in the consultation group. A rapid screening process can provide an adequate tool to identify women who are more likely to have such complications due to depression.

Introduction: Examination of the burnout syndrome in various healthcare fields has paramount importance for a better understanding of the disorder as well as for the establishment of a suitable preventive and intervention program. The surgical departments' employees are at risk among healthcare workers, so it is our objective to further expand the knowledge on the characteristics of the burnout syndrome among the Hungarian surgical staff. Additionally, we compare the results obtained from the Department of Surgery at the University of Szeged with the results of the Department of Emergency Medicine. Aim: Aim of this study is to examine the burnout syndrome and its associations with different variables among the workers of the Department of Surgery at the University of Szeged, and to compare the data with a previous study conducted at the Department of Emergency Medicine at the University of Szeged. Method: Cross-sectional design utilizing a self-administrated questionnaire was used to collect data from the staff. Burnout was measured using the Maslach Burnout Inventory, while psychological immune competence was measured using the Psychological Immune Competence Questionnaire. Results: Based on statistical analysis, the number of weekly working hours and the number of somatic symptoms have a negative impact on burnout, while the greater number of high-quality social relationships and the stronger psychological immune competence have proven to be protective factors. Comparing the Department of Surgery and Department of Emergency Medicine at the University of Szeged, we found a difference in the age of the workers, the number of years spent in the healthcare as well as the scores on the burnout depersonalization scale. Conclusions: The results obtained show further correlations and reveal protective and risk factors in burnout which can be a key to establishing preventive and intervention strategies.

Background: Lower urinary tract infections (LUTIs) are amongst the most common community acquired infections with frequent antibiotic prescribing. Objectives: To assess empiric antibiotic choice in different types of lower urinary tract infections. We also aimed to identify determinants of fluoroquinolone prescribing, as well as to determine the rate of short antibiotic courses. The frequencies of executing laboratory tests and recommending analgesics/anti-inflammatory drugs were also assessed. Methods: A prospective observational study was performed in 19 different Hungarian primary care practices. Participating general practitioners (GPs) filled out data sheets for each patient with a suspected urinary tract infection. Details of drug use were evaluated. Comparison of different LUTI groups were made by descriptive statistics and univariate analysis. Possible determinants of fluoroquinolone prescribing were assessed by logistic regression. Results: Data sheets of 372 patients were analyzed. The majority of patients (68.82%) had acute uncomplicated cystitis. While antibiotics were prescribed for almost every patient (uncomplicated cases: 92.58%, complicated cases: 94.83%), analgesics/anti-inflammatory drugs were recommended at a rate of 7.81% in uncomplicated, and 13.79% in complicated cystitis cases. Ciprofloxacin was the most commonly prescribed antibacterial agent in both types of cystitis. Short-term antibiotic therapy was prescribed in one third of relevant cases. Logistic regression found a weak association between fluoroquinolone use and patient's age and presence of complicating factors. Conclusions: Many aspects of suboptimal cystitis management were identified (e.g. unnecessarily broad spectra agents, too long antibiotic courses). In this study, patient characteristics has weakly influenced fluoroquinolone prescribing. Based on these results there is considerable room for improvement in primary care antibiotic therapy of cystitis in Hungary.
RESUMEN
Dental anaesthesia is one of the most frequently performed medical procedures. Although the frequency of ocular complications is low, these can be alarming and can potentially give rise to medicolegal issues. Dentists and oral surgeons should be well-informed of these adverse reactions. Ophthalmologists and emergency physicians might be required for appropriate care of these patients. Fortunately, most ocular complications related to dental anesthesia are transient. Differential diagnosis includes stroke and intracranial hemorrhage and so vital signs are to be closely monitored. The planned surgical procedure can be carried out once the patient is fully informed and gave consent. The psychological aspect of such unexpected complication must be managed appropriately. We report a case with diplopia and ophthalmoplegia of a reversible and temporary nature. We also include a literature review of ophthalmologic complications after intraoral local anaesthesia in this paper. Orv Hetil. 2018; 159(52): 2212-2216.

INTRODUCTION: Burnout has been described as a growing problem amongst healthcare workers. Emergency department staffs experience the burden of stress day by day, yet only a few studies have examined their burnout. AIM: In this study we wanted to investigate the burnout and its relations to other variables amongst the employees of the Department of Emergency Medicine in Szeged. METHOD: Cross-sectional design utilizing a self-administered questionnaire was used to collect data from the staff of the Department. Burnout was measured using the Maslach Burnout Inventory. RESULTS: Burnout is considerably prevalent among the workers of the Emergency Department, especially nurses and physicians. The study found negative relation between burnout and age, number of children, number of years in the healthcare system, number of physical symptoms, social support and psychological immune system. Being single was a risk factor. CONCLUSIONS: The risks and protective factors found to be associated with burnout in this study might help to set up institutional prevention and intervention strategies.

Advanced Trauma Life Support (ATLS) programs are recognized as the standard educational trauma program worldwide. Data suggest that ATLS has a positive impact on the value of trauma care. The ATLS Hungary program has been started in 2005, celebrating its 10-year anniversary this year. In the present brief communication a brief overview is provided on the program.Student evaluation and statistical data about the participants were collected throughout the 10-year history of the Hungarian program.Student evaluation shows a high level of satisfaction amongst the participating doctors. Most participants are working in higher level centers. The Hungarian program shows good quality according to the participants. Establishing at least one new center is crucial to be able to provide the course for every professional interested in it or required to take it.
RESUMEN
A 76-year-old female patient was admitted to the Level I Emergency Department of University of Szeged with severe abdominal pain and vomiting. The clinical assessment with laboratory tests and radiological investigations confirmed severe sepsis associated with intravascular hemolysis and multiorgan failure and acute pancreatitis. On the abdominal CT, besides of other abnormalities, the presence of gas bubbles in the stomach, small intestines and liver were seen. The gastric alterations pointed to emphysematous gastritis. Despite of the medical treatment, the patient's condition quickly deteriorated and eight hours after admission the patient died. The autopsy evaluation revealed systemic infection of abdominal origin caused by gas-producing Gram-positive bacteria, and the post-mortem microbiological cultures confirmed the presence of Cloctridium perfringens in many abdominal organs. Emphysematous gastritis seemed to be the primary infectious focus.

BACKGROUND & AIMS: Excessive consumption of ethanol is one of the most common causes of acute and chronic pancreatitis. Alterations to the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) also cause pancreatitis. However, little is known about the role of CFTR in the pathogenesis of alcohol-induced pancreatitis. METHODS: We measured CFTR activity based on chloride concentrations in sweat from patients with cystic fibrosis, patients admitted to the emergency department because of excessive alcohol consumption, and healthy volunteers. We measured CFTR levels and localization in pancreatic tissues and in patients with acute or chronic pancreatitis induced by alcohol. We studied the effects of ethanol, fatty acids, and fatty acid ethyl esters on secretion of pancreatic fluid and HCO3(-), levels and function of CFTR, and exchange of Cl(-) for HCO3(-) in pancreatic cell lines as well as in tissues from guinea pigs and CFTR knockout mice after administration of alcohol. RESULTS: Chloride concentrations increased in sweat samples from patients who acutely abused alcohol but not in samples from healthy volunteers, indicating that alcohol affects CFTR function. Pancreatic tissues from patients with acute or chronic pancreatitis had lower levels of CFTR than tissues from healthy volunteers. Alcohol and fatty acids inhibited secretion of fluid and HCO3(-), as well as CFTR activity, in pancreatic ductal epithelial cells. These effects were mediated by sustained increases in concentrations of intracellular calcium and adenosine 3',5'-cyclic monophosphate, depletion of adenosine triphosphate, and depolarization of mitochondrial membranes. In pancreatic cell lines and pancreatic tissues of mice and guinea pigs, administration of ethanol reduced expression of CFTR messenger RNA, reduced the stability of CFTR at the cell surface, and disrupted folding of CFTR at the endoplasmic reticulum. CFTR knockout mice given ethanol or fatty acids developed more severe pancreatitis than mice not given ethanol or fatty acids. CONCLUSIONS: Based on studies of human, mouse, and guinea pig pancreata, alcohol disrupts expression and localization of the CFTR. This appears to contribute to development of pancreatitis. Strategies to increase CFTR levels or function might be used to treat alcohol-associated pancreatitis.

BACKGROUND: Polymerase chain reaction (PCR)-based techniques are widely used to identify fungal and bacterial infections. There have been numerous reports of different, new, real-time PCR-based pathogen identification methods although the clinical practicability of such techniques is not yet fully clarified.The present study focuses on a novel, multiplex, real-time PCR-based pathogen identification system developed for rapid differentiation of the commonly occurring bacterial and fungal causative pathogens of bloodstream infections. RESULTS: A multiplex, real-time PCR approach is introduced for the detection and differentiation of fungi, Gram-positive (G+) and Gram-negative (G-) bacteria. The Gram classification is performed with the specific fluorescence resonance energy transfer (FRET) probes recommended for LightCycler capillary real-time PCR. The novelty of our system is the use of a non-specific SYBR Green dye instead of labelled anchor probes or primers, to excite the acceptor dyes on the FRET probes. In conjunction with this, the use of an intercalating dye allows the detection of fungal amplicons.With the novel pathogen detection system, fungi, G + and G- bacteria in the same reaction tube can be differentiated within an hour after the DNA preparation via the melting temperatures of the amplicons and probes in the same tube. CONCLUSIONS: This modified FRET technique is specific and more rapid than the gold-standard culture-based methods. The fact that fungi, G + and G- bacteria were successfully identified in the same tube within an hour after the DNA preparation permits rapid and early evidence-based management of bloodstream infections in clinical practice.

BACKGROUND/AIM: Causative agents most frequently encountered in systemic infections are bacteria, although fungi that cause invasive infections have also emerged, mostly in immune-compromised patients. The early detection and adequate treatment of bloodstream infections are critical for successful treatment. The aim of this study was to develop a rapid and efficient method for the detection and differentiation of the most common fungal pathogens. MATERIALS AND METHODS: Real-time Polymerase chain reaction (PCR) and consecutive high-resolution melting analysis was used for the detection and differentiation of fungal pathogens. RESULTS: The developed analysis procedure proved appropriate for discrimination of the ten most relevant Candida species, four Aspergillus species, and Cryptococcus neoformans. The sensitivity of the PCR reaction was 5, which is suitable for the detection of these fungi in blood. CONCLUSION: This technique is not adaptable as a general identification method, but it is highly useful when certain fungal species are to be expected in clinical samples.
