Abstract
BACKGROUND Mid-regional pro-adrenomedullin (MR-proADM) is useful for risk stratification in patients with sepsis and respiratory infections. The study's purpose was to assess the available data and determine the association between MR-proADM levels and mortality in COVID-19 participants. METHODS A comprehensive literature search of medical electronic databases was performed including PubMed, Web of Science, Scopus, Cochrane, and grey literature for relevant data published from 1 January 2020, to 20 November 2022. Mean differences (MD) with 95% confidence intervals (CI) were calculated. RESULTS Fourteen studies reported MR-proADM levels in survivors vs. non-survivors of COVID-19 patients. Pooled analysis showed that MR-proADM level in the survivor group was 0.841 ± 0.295 nmol/L for patients who survive COVID-19, compared to 1.692 ± 0.761 nmol/L for non-survivors (MD = -0.78; 95%CI: -0.92 to -0.64; p < 0.001). CONCLUSIONS The main finding of this study is that mortality of COVID-19 is linked to MR-proADM levels, according to this meta-analysis. The use of MR-proADM might be extremely beneficial in triaging, assessing probable therapy escalation, predicting potential complications during therapy or significant clinical deterioration of patients, and avoiding admission which may not be necessary. Nevertheless, in order to confirm the obtained data, it is necessary to conduct large prospective studies that will address the potential diagnostic role of MR-proADM as a marker of COVID-19 severity.KEY MESSAGESSeverity of COVID-19 seems to be linked to MR-proADM levels and can be used as a potential marker for predicting a patient's clinical course.The use of MR-proADM might be beneficial in triaging, assessing probable therapy escalation, predicting potential complications during therapy or significant clinical deterioration of patients, and avoiding admission which may not be necessary.For patients with COVID-19, MR-proADM may be an excellent prognostic indicator because it is a marker of endothelial function that may predict the precise impact on the equilibrium between vascular relaxation and contraction and lowers platelet aggregation inhibitors, coagulation inhibitors, and fibrinolysis activators in favor of clotting factors.

Abstract
The novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection and the accompanying coronavirus disease (Covid-19) have shifted the priority of human and technical resources toward their handling, thus affecting the usual standards of care for populations diagnosed with other clinical entities. The phenomenon becomes even more apparent in patients with presenting symptoms of mental and behavioral disorders, a category already vulnerable and underrepresented in regard to its prehospital approach and management. For the purposes of the current retrospective cohort study, we used records of the Polish National Emergency Medical Service Command Support System for the time period between April 1, 2019 and April 30, 2021, the official register of medical interventions delivered in Poland by Emergency Medical Services (EMS). We aimed to examine the potential impact of the COVID-19 pandemic across the Masovian Voivodeship on individuals seeking medical care for mental and behavioral disorders pertaining in the "F" category of the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10). We examined the individuals' baseline characteristics, prehospital vital parameters and EMS processing times in a population of 59,651 adult patients (04/2019-03/2020, 28,089 patients, 04/2020-03/2021, 31,562 patients) handled by EMS teams. Compared to pre-COVID-19, EMS personnel handled fewer patients, but more patients required mental and behavioral care. Throughout the duration of the pandemic, all prehospital time periods were significantly delayed due to the increased time needed to prepare crew, vehicles, and technical equipment to ensure COVID-19 prevention and overcrowding in Emergency Departments (EDs).

Abstract
The available meta-analyses have inconclusively indicated the advantages of video-laryngoscopy (VL) in different clinical situations; therefore, we conducted a systematic review and meta-analysis to determine efficacy outcomes such as successful first attempt or time to perform endotracheal intubation as well as adverse events of VL vs. direct laryngoscopes (DL) for double-lumen intubation. First intubation attempt success rate was 87.9% for VL and 84.5% for DL (OR = 1.64; 95% CI: 0.95 to 2.86; I2 = 61%; p = 0.08). Overall success rate was 99.8% for VL and 98.8% for DL, respectively (OR = 3.89; 95%CI: 0.95 to 15.93; I2 = 0; p = 0.06). Intubation time for VL was 43.4 ± 30.4 s compared to 54.0 ± 56.3 s for DL (MD = −11.87; 95%CI: −17.06 to −6.68; I2 = 99%; p < 0.001). Glottic view based on Cormack–Lehane grades 1 or 2 equaled 93.1% and 88.1% in the VL and DL groups, respectively (OR = 3.33; 95% CI: 1.18 to 9.41; I2 = 63%; p = 0.02). External laryngeal manipulation was needed in 18.4% cases of VL compared with 42.8% for DL (OR = 0.28; 95% CI: 0.20 to 0.40; I2 = 69%; p < 0.001). For double-lumen intubation, VL offers shorter intubation time, better glottic view based on Cormack–Lehane grade, and a lower need for ELM, but comparable first intubation attempt success rate and overall intubation success rate compared with DL.

Abstract
AIM The aim of the study was to assess the usefulness of the Glasgow Coma Scale (GCS) score assessed by EMS team in predicting survival to hospital discharge in patients after out-of-hospital cardiac arrest (OHCA). METHODS Silesian Registry of OHCA (SIL-OHCA) is a prospective, population-based regional registry of OHCAs. All cases of OHCAs between the 1st of January 2018 and the 31st of December 2018 were included. Data were collected by EMS using a paper-based, Utstein-style form. OHCA patients aged ≥18 years, with CPR attempted or continued by EMS, who survived to hospital admission, were included in the current analysis. Patients who did not achieve return of spontaneous circulation (ROSC) in the field, with missing data on GCS after ROSC or survival status at discharge were excluded from the study. RESULTS Two hundred eighteen patients with OHCA, who achieved ROSC, were included in the present analysis. ROC analysis revealed GCS = 4 as a cut-off value in predicting survival to discharge (AUC 0.735; 95%CI 0.655-0.816; p < 0.001). Variables significantly associated with in-hospital survival were young age, short response time, witnessed event, previous myocardial infarction, chest pain before OHCA, initial shockable rhythm, coronary angiography, and GCS > 4. On the other hand, epinephrine administration, intubation, the need for dispatching two ambulances, and/or a physician-staffed ambulance were associated with a worse prognosis. Multivariable logistic regression analysis revealed GCS > 4 as an independent predictor of in-hospital survival after OHCA (OR of 6.4; 95% CI 2.0-20.3; p < 0.0001). Other independent predictors of survival were the lack of epinephrine administration, previous myocardial infarction, coronary angiography, and the patient's age. CONCLUSION The survival to hospital discharge after OHCA could be predicted by the GCS score on hospital admission.

Abstract
Background Recently, several randomized controlled trials (RCTs) have evaluated the effect of N95 respirators compared with medical masks to protect against acute respiratory infections. However, these studies are limited by modest sample sizes and inconclusive results. Therefore, the goal of the present study was to review the relevant and available published RCTs with the aid of the increased power of meta-analytic methods in order to assess the effectiveness of medical masks and N95 respirators in reducing the risk of respiratory infections. Methods This meta-analysis follows the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for conducting and reporting results. We searched PubMed, Web of Science, Embase, and Cochrane databases from inception through April 1, 2020 to identify potentially relevant studies. Two authors (LS and JS) independently searched the titles and abstracts of the potentially eligible articles. They independently retrieved required data from the eligible trials; the data were initially tabulated for statistical analysis. Two authors (JRL and LS) independently assessed the methodological quality of the included RCTs using the Cochrane Collaboration’s tool for assessing risk of bias. Results Six articles met the inclusion criteria. The pooled analysis showed that N95 respirators did not reduce the risk of infection with respiratory viruses compared with medical/surgical masks (5.7% vs. 7.9%; RR = 1.12; 95% CI: 0.88–1.41; p = 0.36); however, there was no statistically significant difference in laboratory-confirmed influenza between N95 and medical masks (RR = 0.91; 95% CI: 0.77–1.07; p = 0.26). Medical masks provided similar protection against other viruses, including coronavirus (RR = 0.74; 95% CI: 0.32–1.73; p = 0.49). Respiratory illness, as well as influenza-like illness were less frequently observed with N95 respirators. Conclusions Our meta-analysis suggests that there are insufficient data to definitively determine whether N95 respirators are superior to medical masks in protection against transmissible acute respiratory infections. Further randomized trials are necessary to compare the above methods of respiratory protection in the context of COVID-19 incidence.

Abstract
Background Incidence of difficult endotracheal intubation ranges between 3 and 10%. Bougies have been recommended as an airway adjunct for difficult intubation, but reported success rates are variable. A new generation flexible tip bougie appears promising but was not investigated so far. We therefore compared the new flexible tip with a standard bougie in simulated normal and difficult airway scenarios, and used by experienced anesthesiologists. Methods We conducted a observational, randomized, cross-over simulation study. Following standardized training, experienced anesthesiologists performed endotracheal intubation using a Macintosh blade and one of the bougies in six different airway scenarios in a randomized sequence: normal airway, tongue edema, pharyngeal obstruction, manual cervical inline stabilization, cervical collar stabilization, cervical collar stabilization and pharyngeal obstruction. Overall success rate with a maximum of 3 intubation attempts was the primary endpoint. Secondary endpoints included number of intubation attempts, time to intubation and dental compression. Results Thirty-two anesthesiologist participated in this study between January 2019 and May 2019. Overall success rate was similar for the flexible tip bougie and the standard bougie. The flexible tip bougie tended to need less intubation attempts in more difficult airway scenarios. Time to intubation was less if using the flexible tip bougie compared to the standard bougie. Reduced severity of dental compression was noted for the flexible tip bougie in difficult airway scenarios except cervical collar stabilization. Conclusion In this simulation study of normal and difficult airways scenarios, overall success rate was similar for the flexible tip and standard bougie. Especially in more difficult airway scenarios, less intubation attempts, and less optimization maneuvers were needed if using the flexible tip bougie.

Abstract
BACKGROUND There is considerable evidence that prolonged use of cervical collars potentially cause detrimental effects including increase in optic nerve sheath diameter (ONSD) among healthy volunteers. Different types of cervical collars immobilize cervical spine variably well and may presumably differently influence the venous compression and hence the intracranial pressure. We therefore aimed to evaluate the influence of cervical spine immobilization with 5 different types of cervical collars on ONSD measured noninvasively by ultrasound on healthy volunteers. METHODS We conducted a randomized crossover trial including 60 adult healthy volunteers. Control assessment of the optic nerve sheath thickness was performed in both sagittal and transverse planes. Patient was placed supine on a transport stretcher, cervical collar was placed, and ONSD measurement was performed after 5 and 20 minutes. During the next days, the procedure was repeated with random allocation of participants and random cervical collar. RESULTS Sixty healthy volunteers were included in our study. ONSD left diameter [mm] for the baseline was 3.8 [interquartile range (IQR): 3.65-3.93)] mm. Using AMBU after 5 min, ONSD was changed up to 4.505 (IQR 4.285-4.61; P < .001) mm. The largest change at 5 minutes and 20 minutes was using Philly 4.73 (IQR: 4.49-4.895; P < .001) and 4.925 (IQR: 4.65-5.06; P < .001), respectively. Necklite reported the lower change in ONSD: 3.92 (IQR: 3.795-4; P = 1.0) mm in 5 minutes and 3.995 (IQR: 3.875 - 4.1; P = 1.0) mm in 20 minutes. ONSD right diameter [mm] for the baseline was 3.8 (IQR 3.675-3.9) mm. Using AMBU after 5 minutes, ONSD was changed up to 4.5 (IQR 4.21-4.6) mm. The largest change at 5 minutes and 20 minutes was using Philly 4.705 (IQR 4.455-4.9) and 4.93 (IQR 4.645-5.075), respectively. Necklite reported the lower change in ONSD -33.9 (IQR 3.795-3.99) mm in 5 minutes and 3.995 (IQR 3.86-4.09) mm in 20 minutes. CONCLUSION We report significant increase of ONSD from the baseline after cervical collar placement among healthy volunteers at 5 minutes and 20 minutes interval. In addition, no significant difference was noted between ONSD measurements at 5 and 20 minutes. Clinicians should take proactive steps to assess the actual need of cervical collar case by case basis. Nonetheless, when needed, Necklite moldable neck brace seems to be a reasonable option.Registration: ClinicalTrials database (www.clinicaltrials.gov, NCT03609879).

Abstract
BACKGROUND A 2017 update of the resuscitation guideline indicated the use of cardiopulmonary resuscitation (CPR) feedback devices as a resuscitation teaching method. The aim of the study was to compare the influence of two techniques of CPR teaching on the quality of resuscitation performed by medical students. METHODS The study was designed as a prospective, randomized, simulation study and involved 115 first year students of medicine. The participants underwent a basic life support (BLS) course based on the American Heart Association guidelines, with the first group (experimental group) performing chest compressions to observe, in real-time, chest compression parameters indicated by software included in the simulator, and the second group (control group) performing compressions without this possibility. After a 10-minute resuscitation, the participants had a 30-minute break and then a 2-minute cycle of CPR. One month after the training, study participants performed CPR, without the possibility of observing real-time measurements regarding quality of chest compression. RESULTS One month after the training, depth of chest compressions in the experimental and control group was 50 mm (IQR 46-54) vs. 39 mm (IQR 35-42; p = 0.001), compression rate 116 CPM (IQR 102-125) vs. 124 CPM (IQR 116-134; p = 0.034), chest relaxation 86% (IQR 68-89) vs. 74% (IQR 47-80; p = 0.031) respectively. CONCLUSIONS Observing real-time chest compression quality parameters during BLS training may improve the quality of chest compression one month after the training including correct hand positioning, compressions depth and rate compliance.

Abstract
Electrocardiography (ECG) is essential to detect and diagnose life threatening cardiac conditions and to determine further treatment. Correct interpretation of an ECG can be challenging, especially in the out-of-hospital setting and by less experienced emergency team members.The aim of this study was to compare the rate of ECG transmission from an out-of-hospital emergency scene to an in-hospital cardiologist on call in EMS-B and EMS-S providers and its impact on direct transportation to a cardiac catheterization laboratory and hospital admission.The study was designed as an observational study. Data from 3 separate emergency medical service teams were collected. Two teams are staffed by paramedics only (EMT-B), while another specialized team is staffed with an emergency physician (EMT-S). 5864 out-of-hospital emergencies were performed during a 12-month period and were analyzed for this study.In 124 out of 5864 (2.1%) out-of-hospital emergencies, an ECG transmission from the out-of-hospital scene to an in-hospital cardiologist on call was performed. Rate of transmission was similar between both teams (EMT-B n = 70, 2.2% vs EMT-S n = 54, 2.0%, P = .054). After coordinating with the cardiologist on call, 11 patients (15.7%) of the EMT-B (15.7%) and 24 patients (44.4%) of the EMT-S were directly transported from the scene of emergency to a cardiac catheterization laboratory (P < .001). Overall, 80% of patients treated by EMT-S, compared to 52.5% treated by the EMT-B required subsequent hospital admission (P < .05).Transmission of ECG from the out-of-hospital emergency scene to the in-hospital cardiologist is infrequently performed. The rate of STEMI in transmitted ECG's by emergency teams staffed with an emergency physician was higher compared to emergency teams staffed with paramedics only.

Abstract
BACKGROUND Endotracheal intubation (ETI) can be challenging, especially in life-threatening situations such as cardiopulmonary resuscitation (CPR). Videolaryngoscopes aim to ease ETI, but effort is still widely discussed. This study intended to investigate 2 different airway devices regarding the success rate of ETI during ongoing chest compressions. METHODS This randomized, cross-over, multi-center manikin trial included 85 experienced paramedics actively working in the emergency medicine service. After a standardized training session, all paramedics underwent 3 airway scenarios using both, direct laryngoscopy using a Macintosh blade and videolaryngoscope (the UEScope): normal airway without chest compressions, normal airway with uninterrupted chest compressions, and difficult airway with uninterrupted chest compressions. The primary outcome was successful ETI, defined as successful placement of the endotracheal tube within the manikin's trachea. Secondary outcomes were number of intubation attempts, time to successful ETI, time to best glottis view, best percent of glottic opening, best glottic view score (Cormack and Lehane), occurrence of dental trauma, ease of use, and willing to reuse in real-life situations. RESULTS The UEScope provided a better glottis visualization, and higher first pass intubation success rate compared to direct laryngoscopy in all 3 scenarios. The overall intubation success was higher, and the intubation time was shorter with the UEScope in scenario B and scenario C, but was comparable in scenario A. Dental compression occurred less often using the UEScope and paramedics rated intubation using the UEScope easier compared to direct laryngoscopy in all 3 airway scenarios. CONCLUSION In simulated CPR scenarios, intubation with the UEScope resulted in a better glottis visualization, a higher intubation success, and a shorter intubation time compared to Macintosh laryngoscope (MAC). Moreover, in situations where the airway is difficult for ETI especially by the paramedic, the UEScope would be a better choice than the MAC. Further studies are needed to confirm these results in real-life patients.

Abstract
Sudden cardiac arrest (SCA) is a significant medical and social issue, the main cause of death in Europe and the United States.The aim of the research was to evaluate the effectiveness of emergency medical procedures applied by emergency medical teams in prehospital care in the context of return of spontaneous circulation (ROSC).The case-control study was based on the medical documentation of the Rescue Service in Katowice (responsible for monitoring 2.7 million inhabitants of the region) referring to 2016. The research involved exclusively adults (ie, individuals older than 18 years) with out-of-hospital cardiac arrest (OHCA). After considering the above inclusion criteria, there were 1603 dispatch order forms (0.64% of all dispatch orders) involved in further research.On the basis of the emergency medical procedure forms, the actions of emergency medical teams were verified as medical procedures (endotracheal intubation, the use of suction pumps, defibrillation, the use of alternatives providing airway patency and ROSC was determined.The analysis covered 1603 cases of OHCA. SCA turned out more frequent in men than in women (P = .000). Most often, SCA occurred in domestic conditions during the day and was witnessed by a third person. In 59.9% of the cases, actions were taken by witnesses, which increased the probability of ROSC. Patients were usually intubated (51.4%). Respirators were used less frequently (20.2%). Ventricular fibrillation (VF) was reported only in 22.0% of the cases. The ROSC rate was higher in the group of patients with diagnosed VF than in those with nonshockable rhythms (VF, 55.43% vs asystole, 24.05%; P = .000).Successful resuscitation depends on the quality of emergency medical procedures performed at the place of incident. The highest probability of ROSC is related with defibrillation (in the cases of VF or ventricular tachycardia with no pulse), intubation, the application of a respirator, and performing mechanical ventilation, as well as with a shorter time from dispatch to arrival.

Abstract
BACKGROUND AND AIM Recent American Heart Association guidelines from 2010 and 2015 stressed the importance of high-quality chest compression and defined standards for compression rate, depth, recoil, and maximal acceptable time for interruptions. High-quality cardiopulmonary resuscitation (CPR) is the "cornerstone" of a system of care that can optimise outcomes beyond the return of spontaneous circulation. METHODS One hundred medical students were enrolled to the study. Study participants, after attending a Basic Life Support Course according to American Heart Association 2015 guidelines, performed 2-min CPR on a Resusci Anne® QCPR Mani-kin. The following data were collected: age, sex, and health status. The study made use of a Tanita MC-980 MA for body composition analysis. RESULTS Mean height of participants was 170.2 ± 8.3 cm, and mean weight was 65 ± 11.8 kg. Mean body mass index was 22.1 ± 2.7, and mean fat-free mass (FFM) was 50.1 ± 10.5 kg. The mean fat mass (FAT%) was 22.9 ± 7.6. Basal metabolic rate, FFM, trunk muscle mass, left arm muscle mass, and right arm muscle mass were positively correlated with compression depth (all p for trend < 0.05). Mean compression depth was 49.7 ± 8.4 (for female 48.7 ± 7.9 mm, for male 42.4 ± 9.5 mm; p = 0.144). Compression rate for males and females was the same, at 114 ×/min (p = 0.769). CONCLUSIONS In our study, basal metabolic rate, FFM, trunk muscle mass, and left and right arm muscle mass were positively correlated with compression depth. Moreover, an arm muscle mass rise of 1 kg caused a rise of compression depth param-eter of 7.3 mm, while when chest compression was performed by females, a fall of compression depth of 3.3 mm was seen.

Abstract
BACKGROUND Drowning is a common issue at many pools and beaches, and in seas all over the world. Lifeguards often act as bystanders, and therefore adequate training in high-quality cardiopulmonary resuscitation (CPR) and use of adequate equip-ment by lifeguards is essential. AIM The aim of this study was to evaluate the impact of the recently introduced CPRMeter (Laerdal, Stavanger, Norway) on quality of CPR, if used by moderately experienced CPR providers. In particular, we tested the hypothesis that using the CPRMeter improves quality of chest compression by lifeguards compared to standard non-feedback CPR. METHODS The study was designed as prospective, randomised, cross-over manikin trial. Fifty lifeguards of the Volunteer Water Rescue Service (WOPR), a Polish nationwide association specialised in water rescue, participated in this study. Participants were randomly assigned 1:1 to one of two groups: a feedback group and a non-feedback group. Participants swim a distance of 25 m in the pool, and then they were asked to haul a manikin for the second 25 m, simulating rescuing a drowning victim. Once participants finished the second 25-m distance, participants were asked to initiate 2-min basic life support according to the randomisation. RESULTS The median quality of CPR score for the 2-min CPR session without feedback was 69 (33-77) compared to 84 (55-93) in the feedback group (p < 0.001). Compression score, mean depth, rate of adequate chest compressions/min, and overall mean rate during the CPR session improved significantly in the feedback group, compared to the non-feedback group. CONCLUSIONS Using the visual real-time feedback device significantly improved quality of CPR in our relatively unexperienced CPR providers. Better quality of bystander CPR is essential for clinical outcomes, and therefore feedback devices should be considered. Further clinical studies are needed to assess the effect of real-time visual devices, especially in bystander-CPR.

Abstract
Obesity is a growing health, social, and economic issue and became an epidemic, according to recent report of World Health Organization.The only method with scientifically proved efficiency of body mass loss is a surgical treatment. Laparoscopic sleeve gastrectomy (LSG) is recently a leading method in metabolic surgery. There are no standards of operative technique for LSG so far. The influence of technique modification on metabolic effect has not been described clearly.The aim of this study was to evaluate metabolic effects in patients with morbid obesity who underwent various surgical approaches of LSG.The study included 120 patients who were randomly divided into 3 groups: Group I, where bougie size was 32 French (Fr), Group II-36 Fr and Group III-40 Fr. Each group was divided into 2 subgroups, based on the distance of resection beginning from the pylorus-2 or 6 cm. Statistical analysis of: body mass index (BMI), the Percentage of Excess Weight Loss (%EWL), the Percentage of Excess BMI Loss (%EBMIL), levels of glucose and insulin on an empty stomach, glycated hemoglobin (HbA1c), insulin resistance (Homeostatic Model Assessment of Insulin Resistance Index-HOMA-IR), aspartate transaminase (AST), alanine transaminase (ALT), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG), and C-reactive protein (CRP) were under investigation.Statistically significant decrease in body mass, BMI, %EWL, %EBL, glucose, and insulin concentrations has been observed in all studied groups. It was the highest when the smallest calibration tube has been used (32 Fr). Similar results were observed in HOMA-IR and HbA1c levels. Statistically significant decrease of total cholesterol, LDL, and TG concentrations have been observed. Significant increase of HDL in every group has been also noted. Postoperative CRP values were the lowest when the smallest bougie was used.LSG is effective method of obesity treatment. Metabolic effects of LSG are the most noticeable when a small bougie size is used.

Abstract
BACKGROUND Sudden cardiac arrest (SCA) is a frequent cause of death in the developed world. Early defibrillation, preferably within the first minutes of the incident, significantly increases survival rates. Accessible automated external defibrillators (AED) in public areas have been promoted for many years, and several locations are equipped with these devices. AIM The aim of the study was to assess the real-life availability of AEDs and assess possible sources of delay. METHODS The study took place in the academic towns of Poznan, Lodz, and Warsaw, Poland. The researchers who were not aware of the exact location of the AED in the selected public locations had to deliver AED therapy in simulated SCA scenarios. For the purpose of the trial, we assumed that the SCA takes place at the main entrance to the public areas equipped with an AED. RESULTS From approximately 200 locations that have AEDs, 78 sites were analysed. In most places, the AED was located on the ground floor and the median distance from the site of SCA to the nearest AED point was 15 m (interquartile range [IQR] 7-24; range: 2-163 m). The total time required to deliver the device was 96 s (IQR 52-144 s). The average time for discussion with the person responsible for the AED (security officer, staff, etc.) was 16 s (IQR 0-49). The AED was located in open access cabinets for unrestricted collection in 29 locations; in 10 cases an AED was delivered by the personnel, and in 29 cases AED utilisation required continuous personnel assistance. The mode of accessing the AED device was related to the longer discussion time (p < 0.001); however, this did not cause any significant delay in therapy (p = 0.132). The AED was clearly visible in 34 (43.6%) sites. The visibility of AED did not influence the total time of simulated AED implementation. CONCLUSIONS We conclude that the access to AED is relatively fast in public places. In the majority of assessed locations, it meets the recommended time to early defibrillation of under 3 min from the onset of the cardiac arrest; however, there are several causes for possible delays. The AED signs indicating the location of the device should be larger. AEDs should also be displayed in unrestricted areas for easy access rather than being kept under staff care or in cabinets.

Abstract
BACKGROUND Immobilization of the cervical spine is indicated in all patients with the potential risk of any cervical spine injury. Airway management in these patients is challenging and direct laryngoscopy is the standard of care. Videolaryngoscopes like the ET-View were introduced into clinical practice to provide better airway visualization and ease intubation. The ET-View is essentially a conventional endotracheal tube, but is equipped with a miniature camera on the tip. The ET-View has not been investigated in patients with immobilized cervical spine so far. The aim was to evaluate the performance of the VivaSight SL compared with Macintosh when performed in patients with immobilized cervical spine by unexperienced physicians. METHODS This was prospective, randomized, cross-over manikin trial. 50 novice physicians were randomly assigned to intubate a manikin in three airway scenarios including a normal airway and two cervical immobilization techniques. Overall and first intubation attempt success rate, time to intubation, dental compression and airway visualization according to the Cormack&Lehane graduation were assessed. RESULTS All physicians were able to intubate the manikin in all scenarios using the ETView, whereas direct laryngoscopy failed in 16 % with immobilized cervical spine using the patriot cervical extraction collar. First intubation attempt success rate was higher and airway visualization was better in all three scenarios using the ET-View compared to direct laryngoscopy. CONCLUSION The ET-View offered much better 62 airway visualization and provided higher overall and first intubation attempt success rates. Therefore, the ET-View is a valuable alternative in patients with difficult intubation due to immobilized cervical spine. Further clinical trials are indicated to confirm these findings.

Abstract
Introduction: The aim of this study was to investigate the effects of plasma and tissue angiotensin-converting enzyme inhibitors (ACE-Is) against propofol-induced endothelial dysfunction and to elucidate the involved mechanisms in vitro. Materials and methods: We examined the effects of propofol (50 μM), quinaprilat and enalaprilat (10−5 M) on fibrinolysis (t-PA, PAI-1, TAFI antigen levels), oxidative stress parameters (H2O2 and MDA antigen levels and SOD and NADPH oxidase mRNA levels) and nitric oxide bioavailability (NO2/NO3 concentration and NOS expression at the level of mRNA) in human umbilical vein endothelial cells (HUVECs). Results: We found that both ACE-Is promoted similar endothelial fibrinolytic properties and decreased oxidative stress in vitro. Propofol alone increased the release of antifibrinolytic and pro-oxidative factors from the endothelium and increased mRNA iNOS expression. We also found that the incubation of HUVECs in the presence of propofol following ACE-Is pre-incubation caused weakness of the antifibrinolytic and pro-oxidative potential of propofol and this effect was similar after both ACE-Is. Conclusions: This observation suggests that the studied ACE-Is exerted protective effects against endothelial cell dysfunction caused by propofol, independently of hemodynamics.

Abstract
Angiotensin converting enzyme inhibitors and propofol both exert hypotensive action and may affect hemostasis. We investigated the influence of quinapril and propofol on hemodynamics and hemostasis in renal-hypertensive rats with induced arterial thrombosis. Two-kidney, one clip hypertensive rats were treated with quinapril (3.0 mg/kg for 10 days), and then received propofol infusion (15 mg/kg/h) during ongoing arterial thrombosis. The hemodynamic and hemostatic parameters were assayed. Quinapril exerted a hypotensive effect increasing after propofol infusion. Quinapril showed an antithrombotic effect with the platelet adhesion reduction, fibrinolysis enhancement and oxidative stress reduction. Propofol did not influence thrombosis; however, it inhibited fibrinolysis and showed prooxidative action. The effect of propofol on fibrinolysis and oxidative stress was significantly lower in quinapril-pretreated rats. Mortality was increased among rats treated with both drugs together. Our study demonstrates that pretreatment with quinapril reduced the adverse effects of propofol on hemostasis. Unfortunately, co-administration of both drugs potentiated hypotension in rats, which corresponds to higher mortality.

Abstract
BACKGROUND Carnitine transports fatty acids from the cytoplasm to the mitochondrial matrix, where the fatty acids are oxidized. Chronic alcohol consumption reduces the concentration of carnitine and interferes with oxidative processes occurring in the cell. AIM The assessment of carnitine concentrations in plasma of chronically intoxicated alcohol dependent persons in a 49-day abstinence period. MATERIAL/METHODS The study included 31 patients (5 women and 27 men) aged from 26 to 60 years (44.6 ± 8.9) and 32 healthy subjects (15 women and 17 men) aged 22-60 years (39.8 ± 9.4). The patients' alcohol dependence ranged from 2 to 30 years (13.6 ± 7.5). Examined subjects consumed 75-700 g of ethanol/day (226.9 ± 151.5). Plasma concentrations of free and total carnitine were measured three times: at the first (T0), 30th (T30) and 49th (T49) day of hospital detoxification. Free (FC) and total (TC) carnitine were determined by the spectrophotometric method. Plasma acylcarnitine (AC) concentration was calculated from the difference between TC and FC; then the AC/FC ratio was calculated. To determine statistically significant differences for related variables, Student's t-test was used. RESULTS At T0, alcoholics had significantly lower concentration of FC and TC (p < 0.05) in plasma, as compared to the control group. In comparison to controls, at T30, plasma TC and FC (p < 0.01) as well as AC (p < 0.001) were reduced. The lowest concentration of TC, FC and AC (p < 0.001)was found at T49. The ratio of AC/FC at T0 had a tendency to be higher in alcoholics than in the control group (p = 0.05), whereas at T49 it was significantly lower in alcoholics as compared to the control subjects (p < 0.05). CONCLUSIONS Chronic alcohol intoxication causes a plasma deficiency of carnitine. Forty-nine days of abstinence showed a significant decrease in the concentration of TC, FC and AC. Further research is necessary to clarify whether a low level of plasma carnitine after chronic alcohol intoxication is caused by the uptake of blood carnitine by tissues such as liver or muscles. In alcoholics the supplementation of carnitine is recommended in the case of a low level of plasma carnitine.

Abstract
The purpose of this study was to evaluate the effect of chronic alcohol intoxication and smoking on the concentration and output of salivary lysozyme. Thirty seven men participated in the study, including 17 male smoking alcohol-dependent patients after chronic alcohol intoxication (AS), and 20 control non-smoking male social drinkers (CNS) with no history of alcohol abuse or smoking. The level of lysozyme was assessed by the radial immunodiffusion method. Significantly lower lysozyme output in the AS group compared to the CNS group was found. Moreover, gingival index was significantly higher in AS than in the CNS group. It appeared that the reduced salivary lysozyme output was more likely the result of ethanol action than smoking. In conclusion, persons addicted to alcohol and nicotine have a poorer periodontal status than non-smoking social drinkers, which may partially be due to the diminished protective effects of lysozyme present in the saliva.

Abstract
The effect of chronic alcohol intoxication and smoking on the output of salivary immunoglobulin A (IgA) was studied in 37 volunteers: 17 male smoking patients after chronic alcohol intoxication (AS) and 20 control non-smoking male social drinkers (CNS). The DMFT index (decayed, missing, or filled teeth), gingival index and papilla bleeding index (PBI) were assessed. Concentration of IgA in saliva was determined by ELISA. Salivary flow (SF) and IgA output were significantly decreased in AS compared to CNS. There were no significant correlations between the amount of alcohol/cigarettes as well as the duration of alcohol intoxication/smoking, and SF or IgA output, nor between IgA level and SF. Gingival index was significantly higher in AS than in CNS, and was inversely correlated with IgA salivary level. The worsened periodontal state in smoking alcohol-dependent persons may result from diminished IgA protection of the oral tissues due to its decreased output.

Abstract
BACKGROUND In hospital patients suffering from adverse clinical and biochemical symptoms of malnutrition, it is often necessary to employ parenteral nutrition to avoid the body's tissue becoming broken down by being metabolised. Thus, the patient's welfare and survival can be supported throughout any periods of medical crisis. Two of the enzymes responsible for metabolising glycoconjugates are alpha-fucosidase (FUC) and beta-glucuronidase (GLU), present in lysosomes. They release fucose or glucuronic acid from the non-reducing end of oligosaccharide chains. OBJECTIVE To determine the effect of parenteral nutrition administered to ill patients, on glycoconjugate metabolism, by measuring serum and urinary activities of FUC and GLU. Material and methods. Blood samples and the daily urine collection were taken from 23 patients' who had been undergoing parenteral nutrition for either 5 or 10 days, as well as from a baseline sample. Enzyme activities in serum and urine were determined by the method of Zwierz et al. RESULTS Serum FUC activities were significantly lower after 10 days compared to 5, (p< 0.0172), whereas GLU activities were significantly lower after both 5 and 10 days, (p< 0.0007 and p< 0.0208 respectively), compared to levels before starting parenteral nutrition. GLU activities were however higher after 10 days than those after 5 days, (p< 0.0023). In urine, FUC activities were significantly decreased after 10 days compared to 5 days after starting parenteral nutrition, (p< 0.0245). Urine GLU activities were unaffected by parenteral nutrition nor was any effect seen on FUC or GLU activities when calculated per 1mg creatinine. CONCLUSIONS Serum FUC and GLU activities can be used for assessing the effect of parenteral nutrition on glycoconjugate metabolism. The significant decreases of serum GLU activity observed after 5 and 10 days, may serve to indicate that the components of parental nutrition are appropriate and that the body has become suitably adapted to this form of nutrition.

Abstract
Peroxidase is the most important antioxidant enzyme in saliva. Through peroxidation of thiocyanate in the presence of H₂O₂, peroxidase catalyses the formation of bacteriocidic compounds such as hypothiocyanate.The purpose of this study was to evaluate the effect of chronic alcohol intoxication and smoking on the activity of oral peroxidase (OPO). A total of 37 volunteers participated in the study. This cohort consisted of 17 male alcohol-dependent smoking patients after chronic alcohol intoxication (AS group, alcohol + smoking) (mean age: 42 years; range: 26-55) (100-700 g/day of alcohol; 10-20 cigarettes/day) and 20 control male social drinkers(CNS group, control non-smokers) with no history of alcohol abuse or smoking (mean age: 42 years; range:30-53). Salivary peroxidase activity was measured by the colorimetric method. The differences between groups were evaluated using the Mann-Whitney U test. There was significantly higher activity of OPO (p = 0.00001)and significantly lower salivary flow (SF) (p = 0.007) in alcohol-dependent smokers after chronic alcohol intoxication compared to the control group. OPO activity significantly correlated with the number of days of alcohol intoxication, but not with smoking. Gingival index (GI) was significantly higher in smoking alcohol-dependent persons than in the control group, and correlated with OPO activity. The sensitivity of the OPO test was 70% in smoking alcoholics, while specificity was 95%. The increased activity of OPO suggests chronic oxidative stress is more likely due to ethanol action than to smoking. Smoking alcohol-dependent persons have a worse periodontal status than controls. OPO activity as a marker of chronic alcohol abuse may help in the diagnosis of alcoholism.

Abstract
There were approximately 93,060 deaths from cancers in Poland in 2008, and about 105,000 are predicted for the year 2025. Early detection of cancer is a major problem throughout the world, which is why many researchers are still looking for specific and sensitive markers of malignant tumors. Our work is a review of recent publications on activity of N-acetyl-β-D-hexosaminidase (HEX) and its isoenzymes A (HEX A) and B (HEX B) as potential markers of malignant tumors. HEX is the most active of the lysosomal exoglycosidases, taking part in degradation of glycoconjugates (glycoproteins, glycolipids, proteoglycans). HEX cleaves N-acetyl-D-glucosamine and N-acetyl-D-galactosamine from non-reducing ends of oligosaccharide chains of glycoproteins, glycolipids and glycosaminoglycans. The activity of HEX, and its isoenzymes A (HEX A) and B (HEX B), was determined by spectrophotometric and isoelectric focusing methods. There was a statistically significant increase in activity of HEX in tumors of the kidney, pancreas, thyroid, colon, ovary, brain, salivary gland, stomach and larynx, which suggests potential applicability of HEX and its isoenzymes in cancer diagnosis.

Abstract
Alcoholism is one of the most frequent dependences among people, leading to damage of the liver and death of the person. Chronic alcohol consumption decreases fatty acid oxidation by interfering with carnitine metabolism and citric acid cycle activity. Block in activity of the citric acid cycle caused by alcohol and its metabolites is partially compensated by increased ketone body production, which results in ketosis. Chronic administration of alcohol induces liver injury, inflammation, cirrhosis, focal necrosis and steatosis. L-carnitine (L-3-hydroxy-4-N, N, N-trimethylaminebutyric acid) is an essential factor in fatty acid metabolism, which plays a major role in transport of activated long-chain fatty acids to sites of β-oxidation in mitochondria. Carnitine also stabilizes cell membranes by removing long-chain acyl-CoA and excess of the acyl group from the body. L-carnitine can be a useful and safe drug in the liver pathology induced by chronic ethanol exposure.

Abstract
BACKGROUND The purpose of the study was to assess the quality of performance of wideband, phase inversion harmonic power Doppler sonography in the diagnosis of focal nodular. MATERIAL/METHODS During a period of one year, thirty-one patients with FNH previously confirmed by ultrasound-guided biopsy, surgical resection, dynamic helical computed tomography or magnetic resonance imaging were examined. The study protocol consisted of B-mode gray scale sonography, color Doppler, power Doppler examinations, and helical CT scans. Then PI scans were performed after the injection of 2.5 g of Levovist intravenously. RESULTS The images obtained by the B-mode gray scale were typical for focal nodular hyperplasia in 13 lesions only (32.5%), and obtained by color, power Doppler sonography in 25 lesions (62%). On the contrary all patients with focal nodular hyperplasia were diagnosed based on the wide-band, phase inversion power Doppler sonography findings. The common enhancement pattern at pulseinversion harmonic US was filling in a central tumor artery with further centrifugal development of contrast. Then during early arterial phase, all typical anatomical features of FNH as 'star sign 'or 'spoke-wheel 'pattern were clearly visible .In 3 cases ,computed tomography and magnetic resonance imaging have failed to disclose pathology while phase inversion sonographic images were completely suggestive which was later confirmed by histologic examination. CONCLUSIONS Our data demonstrates the usefulness of wide-band, phase inversion harmonic power Doppler sonography in the differential diagnosis of hepatic focal nodular hyperplasia by visualizing all characteristic anatomical details.

Abstract
BACKGROUND/AIMS To determine whether examination of hepatic focal nodular hyperplasia by wide-band, phase-inversion sonography offers any advantages over power and color Doppler sonography in the depiction of specific characteristics of these pathologies. METHODOLOGY Twenty-six patients were examined. The presence of focal nodular hyperplasia was confirmed by ultrasound-guided biopsy, surgical resection, dynamic helical computed tomography or magnetic resonance. All patients, prior to enhanced sonography, had undergone B-mode gray-scale sonography, color Doppler, and power Doppler examinations. After injection of 2.5 g of Levovist intravenously, analysis of the contrast agent arrival was performed by wide-band, phase-inversion power Doppler sonography. RESULTS The B-mode gray-scale sonography, color and power Doppler sonography were non-specific for focal nodular hyperplasia in 14 cases in our examination. However based on the wide-band, phase-inversion power Doppler sonography findings all patients with focal nodular hyperplasia were diagnosed. All typical anatomic features of focal nodular hyperplasia such as "star sign" or "spoke-wheel" pattern were clearly visible. In 3 cases, computed tomography and magnetic resonance imaging had failed to disclose pathology while phase-inversion sonographic images were completely suggestive which was later finally confirmed by histologic examination. CONCLUSIONS Our data demonstrate the usefulness of wide-band, phase-inversion power Doppler sonography in the differential diagnosis of hepatic focal nodular hyperplasia by visualizing all characteristic anatomic details.

Abstract
In men, androgens and especially testosterone are considered responsible for the much higher rate of coronary artery disease. The male gender is an independent coronary artery disease risk factor. An adverse correlation between endogenous testosterone levels and the extent of coronary atherosclerosis has been demonstrated in just one study. In our study, we investigated the associations between endogenous sex hormone levels and the extent of coronary atherosclerosis, ejection fraction of the left ventricle and coronary heart disease risk factors.

Abstract
UNLABELLED BACKGROUND. The aim of this study was to evaluate the efficacy of three-dimensional (3D) sonography in liver biopsies. Primarily, the diagnosis of hepatic tumors is based on 2D sonography. This method allows the noninvasive evaluation of the anatomical structure and tumor localization. Interpretation difficulties emerge most often during the assessment of tumor boundaries and their relationships to the blood vessels. METHODS The study included 19 patients, aged 40-75 years (average, 57.5 years) admitted to the Department of General Surgery due to diagnosed liver tumors. RESULTS The livers of all the examined patients displayed focal changes. In order to obtain material for histopathologic examinations, percutaneous needle biopsies were performed, with no complications. CONCLUSIONS 3D sonography generated more information about hepatic changes, due to imaging of multiplanar reconstructions in oblique presentations (which are impossible to present in classical 2D), and thus facilitated design of the biopsy. Evaluation of the biopsy needle visualization inside the tumor with the use of both the 2D and the 3D presentations depends on the subjective approach of the examiner. Based on our knowledge and experience in ultrasonography-guided needle biopsy, we believe 3D sonography-guided biopsy has high efficacy.

Abstract
This clinical study investigated the possible associations of male sex hormone with the extensiveness of coronary artery lesions, coronary heart disease risk factors and ejection fraction of the heart. Ninety six Caucasian male subjects were recruited, 76 with positive and 20 with negative coronary angiograms. Early morning, prior to haemodynamic examination all of them had determined levels of total testosterone, free testosterone, free androgen index (FAI), sex hormone-binding globulin (SHBG), oestradiol, luteinizing hormone, follicle-stimulating hormone, plasma lipids, fibrinogen and glucose. The ejection fraction and the extensiveness of coronary lesions of each subject was assessed on the basis of x-ray examination results using Quantitative Coronary Angiography (QCA) and Left Ventricular Analysis (LVA) packages on the TCS Acquisition workstation, Medcon. Men with proven coronary heart disease had significantly lower levels of total testosterone (11.9 vs 21.2 nmol/l), free testosterone (45.53 vs 86.10 pmol/l), free androgen index (36.7 vs 47.3 IU) and oestradiol (109.4 vs 146.4 pmol/l). The level of testosterone was negatively associated with the DUKE Index. The most essential negative correlation was observed between SHBG and atherogenic lipid profile (low high-density lipoprotein, high triglycerides). Ejection fraction was substantially lower in patients (51.85 vs 61.30) (without prior myocardial infarction) with low levels of free-testosterone (23.85 vs. 86.10 pmol/l) and FAI (28.4 vs 47.3 IU). A negative correlation was observed between total testosterone, free testosterone, FAI and blood pressure, especially with diastolic pressure. Men with proven coronary atherosclerosis had lower levels of endogenous androgens than the healthy controls. For the first time in clinical settings it has been demonstrated that low levels of free-testosterone was characteristic for patients with low ejection fraction. Numerous hypothesies for this action can be proposed but all require a proper evaluation process. The main determinant of atherogenic plasma lipid was low levels of SHBG suggesting its main role in developing atheroscerotic lesions.

Abstract
BACKGROUND/AIMS At present a pancreatic pseudocyst puncture guided by ultrasonography is a treatment of choice in the majority of hospitals. A classical two-dimensional sonography is usually implemented in these cases. However, its shortcomings, mainly in differential diagnosis, are acknowledged by most physicians. The real time monitoring of a fine-needle pseudocyst procedure by two-dimensional ultrasonography is of questionable reliability. In our study we evaluated the usefulness of three-dimensional sonography in the percutaneous fine-needle pancreatic pseudocyst puncture. METHODOLOGY We examined fifty-two patients diagnosed as having pancreatic pseudocysts on the basis of clinical symptoms and two-dimensional ultrasonography findings. Then the decision to qualify certain patients for the percutaneous fine-needle aspiration guided by ultrasonography was made on the basis of two- and three-dimensional scan results. The next step in our investigation was to implement color Doppler in order to visualize all blood vessels at the planned biopsy site. Three-dimensional sonography was used to monitor the tip of the needle making its way to the pancreatic pseudocyst and later inside the fluid collection. RESULTS Pancreatic pseudocysts were diagnosed in all of the 52 cases. Three-dimensional sonography was more precise in visualizing the shape and size than two-dimensional ultrasound scans. CONCLUSIONS Three-dimensional presentation can better visualize irregular shapes, local thickenings, and calcification of pseudocyst walls than classical two-dimensional ultrasound scans. The use of subtraction in three-dimensional scans of blood vessels increases the safety in performing biopsies. It makes the aspiration of cytologic materials much safer to perform. In our study we have shown that three-dimensional sonography collects extremely useful information about the status of the pseudocyst structure and it should become a complementary method to classical ultrasonography. This technique when used on a routine basis ought to help us change the inclusion criteria for guided biopsies.

Abstract
The aim of the study was presentation of our experiences in the diagnostics and treatment of pancreatic carcinoma in confrontation with current opinions. Between 1983 and April 1998 308 patients (198 males and 110 females with mean age 61 years) were treated at our department. In 211 cases tumor was primarily localized in the head and in 97 cases (31.5%) in the body or tail of pancreas. The diagnosis was determined on the basis of clinical symptoms and laboratory investigations. Diagnostic accuracy of performed investigations was as following. Ultrasonography-86%, CT-scan-95%, and ERCP-94%. Ultrasonography or CT guided biopsy and serodiagnostics improved detectability of resectionable carcinoma in the last past years. Among 308 patients, 292 underwent surgery. Since 1997 an intraoperative ultrasonography and cholangioscopy of common bile duct and Virsung were performed as a routine. The procedures depended on the localization and the grade of advance of the tumors. UICC classification of pancreatic tumors, pTNM (4th edition 1987) it was used. Only in 25 patients (8%) (tumors pT1a-bN0M0) it was possible to perform radical operation (resection of the pancreas). However in 172 patients (56%) only palliative procedures were done (pT2N1M0). In 95 patients (31%) only laparotomy and biopsy were performed (tumors pT2N1M1). The study shows that although diagnostic methods are improved, the tumors of the pancreas are diagnosed in stages making unable the radical procedures. Only about 10% of carcinomas are resectable. It is caused by with non-characteristic picture of the disease in its early stage.

Abstract
BACKGROUND/AIMS Fine-needle biopsy (FNB) is one of the diagnostic methods for the diagnosis of focal lesions in the liver. The method is relatively fast, inexpensive and safe. Complications after FNB are observed in only a few cases. Color Doppler sonography (CDS) is one way of minimizing the number of FNB complications. The aim of the present study is to evaluate CDS in the monitoring of FNB in the diagnosis of focal lesions in the liver. METHODOLOGY The patient group consisted of 73 patients: 28 male and 45 female with a mean age of 53.5 years. Initially, all patients were examined using traditional B-mode gray-scale sonography. After visualization of focal lesions in the liver their echostructure and position were analyzed. Color Doppler sonography was the introduced for the visualization of vascularization of the liver. FNB was performed under the guidance of CDS. The cytological specimens obtained were microscopically evaluated. RESULTS Of the 73 patients, 18 cases were diagnosed with liver abscess, 19 with cysts of the liver, and 36 with malignant tumors. Amongst the patients with malignancy tumors, the tumors were unifocal in 15 cases, and multifocal in 221. Histopathologically, there were primary hepatocellular carcinomas in 22 patients and metastatic tumors in 14 patients. During the first 48 hours after FNB no complications such as subcapsular hematoma or intraperitoneal bleeding were observed. CONCLUSIONS Introducing CDS for ultrasound guided percutaneous FNB of the liver avoids such complications as bleeding, especially in patients with a high risk of hemorrhage.

Abstract
Therapeutic results obtained in the management of severe acute pancreatitis (AP) complications are still unsatisfactory, and mortality rate is about 40%. An improvement in treatment effectiveness can be related to successful control of infections and prevention of uncontrollable sepsis. The aim of the study was evaluation of effectiveness of Tienam in the management of severe acute pancreatitis complications. The clinical material included 24 patients, treated for AP between 1994 and 1996. All of the patients were operated on and 19 of them required at least one reoperation. During primary surgery we performed necrosectomy and continuous peritoneal lavage. The analysis of cultures obtained from infected necrotic tissue, pancreatic abscesses and whole blood showed that the infections were caused mainly by Gram-negative bacteria. The highest efficiency in infections control was observed in the case of Tienam (15% resistant strains). The authors emphasize also the increasing role of Staphylococcus aureus and Candida albicans in secondary infections.

Abstract
The aim of the study was the comparative analysis of the degree of intensity of male and female hyperthyroidism treated surgically in the years 1990 to 1996. In this period 295 females and 42 males underwent operation for hyperthyroid goitre. Female predominance was noted in hyperthyroidism (ratio 7:1), in Graves' disease (7.4:1) and in toxic nodular goitre (6.3:1). The clinical findings in pre- and postoperative patients, including laboratory, visual diagnosis, and intra- and postoperative complications were evaluated. In the preoperative period, the incidence of the thyreocardiac syndrome was greater in the male. Male hyperthyroidic goitres were more frequently located retrosternally and caused trachea compression. No significant sexual differences were found in routine laboratory tests. Operations for hyperthyroidic male goitres usually caused more intraoperative problems and were connected with greater blood loss. Estimation of cardio-vascular parameters in the early postoperative period showed higher intensification of hyperkinetic circulation and higher mean body temperature in men. Signs of psychosis developed postoperatively in two men. The analysis of patients with hyperthyroidic goitre treated surgically revealed more severe course of male thyreotoxicosis in the perioperative period.

Abstract
Determinations of collagen in specimens of duodenal mucosa taken from 15 patients operated on because of duodenal ulcer with pyloric stenosis were performed. In the ulcer and surrounding tissue, total collagen values were significantly increased when compared with the results in unchanged wall of the duodenum. Collagen polymorphism study showed considerably higher percentage of type I and decreased type III in the ulceration than in control duodenal mucosa. In conclusion, extracellular components of connective tissue may play a role in the formation and course of duodenal ulcer disease.

Abstract
The production of tumor necrosis factor (TNF-alpha), and interleukin 1 beta (IL-1 beta), IL-6, sTNFR-p55, sTNFR-p75 and their pharmacomodulation were evaluated in a model of septic shock induced in CD-1 mice by cecal ligation and puncture (CLP). This model of sepsis, which resembles the clinical situation of bowel perforation and peritonitis with subsequent septic shock was compared with that induced by administration of pure endotoxin (LPS). TNF-alpha was detectable in serum, liver, spleen and lungs during the first 4 h, with a peak 2 h after CLP. IL-1 beta was measurable in serum after 24 h, and levels increased significantly in spleen and liver 4 and 8 h after CLP. IL-6 levels increased significantly in serum throughout the first 16 h after CLP. sTNFR-p55 and p75 increased in both models of shock but with different kinetics. Cytokines were also detectable after LPS injection, with kinetics similar to those after CLP but a significantly higher level. Pretreatment with dexamethasone (DEX) and ibuprofen (IBU), significantly reduced survival, while TNF did not affect it. Only pentoxifylline (PTX) significantly increased survival in mice with CLP. However DEX protected the mice from LPS mortality. In conclusion, by inhibiting TNF-alpha with DEX and PTX survival was reduced or unchanged respectively, suggesting that the modulation of this cytokine does not play significant role in sepsis and septic shock induced by CLP, unlike treatment with LPS. The negative effects of IBU suggests a protective role by prostaglandins in sepsis induced by LPS.

Abstract
Ultrasound vascular imaging with subtraction is considered as very useful method to evaluation vascularity of tumor and its relationships to great vessels. Lung tumor was evaluated with power color Doppler ultrasound with and without B-mode scanning. Power color Doppler imaging without B-mode scanning is better depicted tumor internal vascular architecture and its relationships to great vessels then with B-mode. This method makes differentiation of tumor character possibly and interventional procedures more safely.

Abstract
A unusual pattern of hepatic fatty infiltration was detected sonographically in 43 patients over a 2-year period. At appropriate gain settings and time gain compensations, the liver parenchyma demonstrated diffuse increased echogenicity except for a solitary hypoechoic area with relatively distinct margins, usually locate in the medial segment of the left hepatic lobe or right lobe in pericholecystic, perivascular or subcapsular locations. This hypoechoic focus varied in size between 15 and 50 mm and was typically ovoid, but was occasionally spherical or irregular in shape. Fourteen patients with such skip area underwent percutaneous needle biopsy because of concern that there was a space-occupying mass. Microscopic examination of specimens from the hypoechoic region revealed normal hepatic parenchymal cells, while tissue samples from the surrounding liver had high fat levels. In the remaining 29 patients, correlative radiologic studies supported the diagnosis of fatty liver and excluded a central-mass lesion. A localized area of normal hepatic tissue should be considered among the possible hypoechoic periportal area demonstrated within a fatty liver.

Abstract
The aim of study was presentation of our experiences in diagnosis and treatment in pancreatic carcinoma in confrontation with current opinions. Between 1984-1995 at our Department was treated 211 patients with carcinoma of exocrine part of the pancreas. It were 137 male and 74 female with mean age 58.9 years. In 151 cases (70.5%) primary seat of tumour was located in the head and in 60 cases (29.5.1%) in the body or tail of pancreas. The diagnosis was determined on the basis of clinical symptoms and laboratory investigation Diagnostic accuracy of X-ray investigations was as follow: Ultrasonography-86%, CT-scan-91%, ERCP-94%. Ultrasonography or CT guided biopsy and serodiagnosis improved detectability of resectionable carcinomas in the last past years. Among 211 patients, 199 underwent surgery. The procedures depended on the localisation and grade of advance of the tumours. UICC classification of pancreatic tumours, pTNM (4th edition 1987) was used. Only in 21 patients (9.9%) (tumours pT1a-b N0M0) was possible to perform radical operation (resection of the pancreas). However in 107 patients (50.7%) were done only paliative procedures (pT2N1M0). In 83 patients (39.3%) only laparotomy and biopsy were performed (tumours pT2N1M1). The study shows that although improvement of the diagnostic methods tumors of the pancreas are diagnosed in stages making unable the radical procedures and only about 10% of carcinomas are resectable. It is relevant with non-characteristic picture of the diseases in its early stages.
