“Examining the link between tooth agenesis and papillary thyroid cancer: is there a risk factor?” Observational study

BackgroundMutations in one or multiple genes can lead to hypodontia and its characteristic features. Numerous studies have shown a strong genetic influence on the occurrence of hypodontia, and identified several genes, including AXIN2, EDA, FGF3, FGFR2, FGFR10, WNT10A, MSX1, and PAX9, that are directly associated with dental agenesis and carcinogenesis. The objective of this study was to investigate the occurrence and pattern of tooth agenesis, microdontia, and palatally displaced canine (PDC) in women diagnosed with papillary thyroid cancer (PTC), compared to a control group of women without any malignancy or thyroid disease.Materials and methodsThis case–control study was carried at the Department of Orthodontics, School of Dental Medicine University of Zagreb, and Department of Oncology and Nuclear Medicine Sestre Milosrdnice University Hospital Centre. The study involved a clinical examination and evaluation of dental status, panoramic X-ray analysis, and assessment of medical and family history of 116 female patients aged 20–40 with PTC, as well as 424 females in the control group who were of similar age.ResultsThe prevalence of hypodontia, microdontia, and PDC was statistically higher in women with PTC than in the control group. The prevalence rate of hypodontia was 11.3% in the experimental group and 3.5% in the control group. The experimental group showed a higher occurrence of missing upper lateral incisors, lower left central incisors, and all the third molars (except the upper left) compared to the control group. Women with PTC showed the prevalence of PDC significantly higher than the control group (3.5%, 0.7%, p = 0.002). The probability of hypodontia as a clinical finding increases 2.6 times, and microdontia occurs 7.7 times more frequently in women with PTC.ConclusionOur study suggests a possible link between odontogenesis and PTC. The absence of permanent teeth may increase the likelihood of PTC in women. Leveraging the age-7 orthopantomogram to identify women at high risk for PTC within a critical early detection window could significantly improve oral health outcomes and PTC prognosis through proactive interventions.

Complete pathological response following neoadjuvant chemoradiotherapy in locally advanced colorectal carcinoma

Background: The prognosis of rectal cancer has improved with neoadjuvant treatment for locally advanced disease. Twenty percent of patients respond to treatment with complete pathological regression, which is clinically estimated with magnetic resonance imaging. Aim: describe the properties of the pathological complete response group of patients at our institution Materials and methods: All selected patients received LCCRT at the University Hospital for Tumors Sestre milosrdnice University Hospital Center, Zagreb, between January 2014 and December 2019 and were later surgically treated at the same facility. Results: We identified 23 patients with complete pathological responses, of which, despite surgery, seven progressed. We recorded a higher proportion of female patients in that group and younger age of onset. MRI preoperatively was not yet predictive of a complete pathological response. Conclusion: The proportion of patients with a complete pathological response is 16% in this cohort. All patients underwent surgery but did not receive consolidating therapy. About 30% progressed during the observed period.

Intermittent tramadol vs tramadol administration via patient-controlled pump after lumbar discectomy: a randomized controlled trial

AimTo compare the effect of intermittent tramadol dosing vs tramadol administration via patient-controlled pump on pain after lumbar discectomy.MethodsThis randomized prospective study enrolled 100 patients who underwent elective LIV-LV lumbar discectomy in the neurosurgery department at Sestre Milosrdnice University Hospital Center from May 2016 to July 2017. Patients were randomized to receive either tramadol (600 mg daily) via a patient-controlled analgesia (PCA) pump or intermittently. Pain was evaluated by the Croatian version of Short-Form McGill Pain Questionnaire.ResultsForty percent of patients were women. The median (interquartile range) age of the patients was 51 (40-61) years. The groups did not differ in pain at 7 pm on the day of discectomy. However, in the morning and evening on the first postoperative day and in the morning and evening of the second postoperative day, the PCA group had significantly lower pain (P = 0.023, P < 0.001, P < 0.001, P = 0.026, respectively).ConclusionThis is the first study that used the Short Form McGill Pain Questionnaire to compare the effect of tramadol administration via PCA pump and intermittent administration on pain after LIV-LV discectomy in a neurosurgery department. Tramadol showed a good analgesic efficacy in lumbar spine surgery; tramadol via PCA controlled pain more effectively than intermittently administered tramadol.Australian New Zealand Clinical Trials Registry: ANZCTR12618001893291.

“The role of L. reuteri DSM17938 in nutritional recovery and treatment of constipation in children and adolescents with anorexia nervosa - a randomized, double blind, placebo controlled study”

Anorexia nervosa (AN) carries the risk of potentially irreversible medical complications, especially in children and adolescents. Constipation is frequent and difficult to manage. Due to the symptoms it causes, constipation can further compromise nutritional rehabilitation. To investigate the role of probiotics (Lactobacillus reuteri DSM 17938) in children and adolescent with AN. Randomized, double blind, placebo controlled study in 31 female pediatric AN patients with constipation, referred to nutritional therapy in Pediatric Gastroenterology Department, Sestremilosrdnice University Hospital Centre in Zagreb. At hospitalization, patients were randomly assigned into two groups; one taking L.reuteri, and other placebo for 3 months, along with the conventional nutritional rehabilitation. Patients were followed 3 months after stopping the treatment. The primary outcome was relief of constipation, assessed after 3 months, while secondary outcomes were normalization of body weight, stool frequency and consistency, relief of dyspepsia, weight gain and recovery of malnutrition regarding bone density and vitamin D3 levels. The study showed statistically significant difference between the two groups considering the stool frequency (6.4 vs. 4.2 stools/week; p<0.05) and normalization of body weight (93 vs. 63%; p=0.04) after 6 months, but no significant effect on the rate of relief of constipation (87 vs. 64%; p=0.22) at 3 months. In the L. reuteri group, the normalization of BMD was achieved in 8/15, whereas in the placebo group, in 3/16 patients. However, there was no statistically significant difference compared to the placebo group regarding the BMD recovery as well as the normalization of D3 levels (p=0.056). Probiotics may serve as simple and safe adjuvant therapy of constipation in childhood AN and contribute to faster nutritional recovery. Although a statistically significant difference between the two group in relief of constipation could not be shown after 3 months, a benefit from probiotics could be in increasing stool frequency and nutritional recovery in childhood AN after six months.

Incidence of cardiovascular events when watching intense football matches – sex differences

Introduction FIFA World Cup represent one of the world's greatest phenomena. The spectators watch the matches of national teams with great emotional involvement. It is well documented fact that emotional stress can be a trigger of unwanted cardiovascular (CV) event. Aim The aim of this retrospective study was to determine whether there had been an increase in the number of the emergency admissions for CVD in the Emergency Room and Clinic for Cardiovascular Diseases of the Sestre milosrdnice University Hospital Centre during and after the matches that the Croatian national team played in the FIFA World Cup 2018. Methods The hospital’s database was examined for the dates when Croatia played its matches, plus two more days after each match. An unexposed period that included the same dates in 2017 and 2019 was formed. Results 1093 cases were assessed. The incidence of CV admissions during the exposed period was 1.15 (95% confidence interval [CI]; 1.02 to 1.31) times higher than during the unexposed period. There was a 1.30 (95% CI; 1.1 to 1.54) times higher incidence in women compared to the unexposed period. Arrhythmias and angina pectoris were the CVDs that occurred more frequently in the exposed period. Conclusion This study showed that watching Croatian national team's matches and cheering represented an additional risk for a CV incident, especially in women.

Turner Syndrome: for successful treatment it is necessary to diagnose it early.

Background Turner Syndrome (TS) is a chromosomal disorder with short stature as the most common feature. The aim of this paper was to show the characteristics of TS patients treated at our Clinic, with an emphasis on their age at diagnosis and the effect of growth hormone therapy on their final height and height gain. Methods This retrospective study is based on the medical records of 37 female pediatric patients aged 0-18 years treated at the Pediatric Department of the Sestre Milosrdnice University Hospital Center from 1997 to 2017. Results Mean age at diagnosis is 7.55±5.13 years. In the observed period a trend towards later diagnosis was shown (P=0.004). Most patients (26) were treated with rhGH. The average height of all patients who reached their final height (N.=30) was 151.49±6.49 cm (standard deviation score [SDS]: -1.73±1.11). The initial height SDS was significantly lower in the treated compared to the untreated patients (P=0.02). The final height was 151.59±7.21 cm (SDS: -1.72±1.3) in the treated and 151.12±5.85 cm (SDS: -1.77±0.94) in the untreated patients. The difference between the initial and final height was significantly greater in the treated patients compared to the untreated patients (30.46 and 16.28 cm, P=0.039). The same was true for the difference between the initial and final height SDS (0.78, or -0.3, P=0.042). Conclusions Based on the results of this research, TS is increasingly diagnosed at a later age. The effect of rhGH therapy was favorable and resulted in a greater height gain in the treated patients.

CONTINUOUS GLUCOSE MONITORING AND TYPE 1 DIABETES MELLITUS CONTROL IN CHILD, ADOLESCENT AND YOUNG ADULT POPULATION - ARGUMENTS FOR ITS USE AND EFFECTS.

SUMMARYSensors for continuous glucose monitoring (CGM) in intercellular fluid are used as a contemporary method to achieve better control in type 1 diabetes mellitus (DM), which is best shown through lower glycated hemoglobin (HbA1c) levels.The aim of this study was to assess how many of our patients used CGM (parents were solely financing all the cost of the device) and what was the effect of CGM on the control of DM. Data were retrospectively collected from medical records of patients actively treated at the Division of Endocrinology, Diabetology, Pulmonology and Allergology, Department of Pediatrics, Sestre milosrdnice University Hospital Center. The t-test was used for independent samples to compare the mean levels of HbA1c before and after the inclusion of CGM. CGM was used by 81 (32.1%) of our patients with type 1 DM, of which 43 met the inclusion criteria. The mean HbA1c level 6 months before the introduction of CGM was 8.2%±1.9 and after 12 months of CGM use it was 7.4%±1.2, which was a statistically significant improvement (p=0.026). Furthermore, our results demonstrated that the greatest improvement in HbA1c level was recorded in the groups of young adults (18-25 years) and youngest children (<12 years). We confirmed the efficacy of CGM in achieving better control of type 1 DM by significantly improving HbA1c levels in a population of highly motivated patients.

The association between alexithymia and two dimensions of major depressive disorder: cognitive and somatic-affective

Aim: To explore the association between alexithymia and two dimensions of major depressive disorder (MDD): cognitive and somatic-affective. Patients and methods. Unicentric, cross-sectional study included consecutive sample of 63 patients at the Department of Psychiatry (DoP), Sestre Milosrdnice University Hospital Centre, Zagreb, Croatia. Target population included outpatients with diagnosed MDD (F32 and F33, according to ICD-10). Inclusion criteria were: confirmed MDD diagnosis, age between 18 and 65 years, both genders, outpatient treatment at the DoP. The main outcome was the association between alexithymia, measured by total score on 20-item Toronto-Alexithymia scale (TAS-20), with two dimensions of MDD, cognitive and somatic-affective, measured by Beck Depression Inventory-II (BDI-II). Results: Both dimensions of BDI-II and the total severity of MDD symptoms were statistically significantly, although low, associated with alexithymia, and the differences between these two correlations were not (statistically) significant. However, in the multivariable model, the cognitive dimension (b = 0.64; β = 0.48; p = 0.002; statistically significant at the false discovery rate of 0.05) was primarily associated with alexithymia, and the somatic-affective was not, after all cognitive aspects were controlled for (b = -0.19; β = 0-0.14; p = 0.491; not statistically significant, with the false discovery rate of 0.05). Conclusion: Alexithymia is primarily associated with a pure cognitive dimension of MDD after somatic-affective elements are excluded. Somatic-affective dimension of MDD is not associated with alexithymia after the cognitive elements were controlled for. Both dimensions, as well as the overall severity of MDD, are associated with alexithymia, but this association is relatively low.

Sepsis and septic shock – an observational study of the incidence, management, and mortality predictors in a medical intensive care unit

AimTo prospectively determine the number of patients with sepsis and septic shock in a medical intensive care unit (ICU) using the Sepsis-3 definition; to analyze patients' characteristics, clinical signs, diagnostic test results, treatment and outcomes; and to define independent risk factors for ICU mortality.MethodsThis prospective observational study enrolled all patients with the diagnosis of sepsis treated in the medical ICU of “Sestre Milosrdnice” University Hospital Center, Zagreb, between April 2017 and May 2018.ResultsOut of 116 patients with sepsis, 54.3% were female. The median age was 73.5 years (IQR 63-82). The leading source of infection was the genitourinary tract (56.9%), followed by the lower respiratory tract (22.4%). A total of 35.3% of the patients experienced septic shock. Total ICU mortality for sepsis was 37.9%: 63.4% in patients with septic shock and 24.0% in patients without shock. Independent risk factors for ICU mortality were reduced mobility level (odds ratio [OR] 11.16, 95% confidence interval [CI] 2.45-50.91), failure to early recognize sepsis in the emergency department (OR 6.59, 95% CI 1.09-39.75), higher Sequential Organ Failure Assessment score at admission (OR 2.37, 95% CI 1.59-3.52), and inappropriate antimicrobial treatment (OR 9.99, 95% CI 2.57-38.87).ConclusionWhile reduced mobility level and SOFA score are predetermined characteristics, early recognition of sepsis and the choice of appropriate antimicrobial treatment could be subject to change. Raising awareness of sepsis among emergency department physicians could improve its early recognition and increase the number of timely obtained specimens for microbial cultures.

Stress Hyperglycaemia Indicates Embolus Size and Localization in Patients with Acute Pulmonary Embolism.

Objective Acute pulmonary embolism is a life-threatening form of venous thromboembolism often causing stress hyperglycaemia. The aim of this study was to determine the prognostic value of stress hyperglycaemia in acute pulmonary embolism, providing new insights into the presumed embolus size and localization, clinical parameters (Pulmonary Embolism Severity Index, PESI), and in-hospital mortality. Design and Methods. Among a total of 95,454 patients referred to the Emergency Department of the Sestre Milosrdnice University Hospital Centre between 2014 and 2016, all patients with acute pulmonary embolism were included into this observational cohort study. The study group consisted of 190 patients aged 25–96. Relevant patient history, clinical data, and laboratory findings were collected during the entire hospitalization period. Data were analyzed for the entire group of patients, as well as separately for patients without diabetes, using the Fisher exact test and logistic regression. Results Analysis of embolus localization as an indirect parameter of embolus size showed that patients with stress hyperglycaemia more often had emboli located in proximal parts of the pulmonary circulation (i.e., main artery or lobar branches) (p < 0.05). Furthermore, stress hyperglycaemia correlated with PESI score and diabetes (p < 0.05) in the entire patient group. Stress hyperglycaemia showed independent association with in-hospital mortality in patients (p < 0.05). Conclusion Stress hyperglycaemia in patients with acute pulmonary embolism is associated with embolus localization in larger arteries of the pulmonary circulation and higher PESI score and therefore could serve as an independent in-hospital mortality predictor.

THE CROATIAN HEALTH INSURANCE FUND DOES NOT RECOGNIZE DIFFERENCES IN THE COST OF DIFFERENT TREATMENTS FOR REVISION TOTAL HIP ARTHROPLASTY.

SUMMARYIn recent years, there has been increased interest in the cost of treatment for revision interventions for hip and knee prostheses. In all publications so far, the authors note the high cost of treatment for revision interventions, especially if infection is present. The aim of this study was to compare the cost of treatment and health insurance reimbursements between revision total hip arthroplasty (THA) for infection and revision for aseptic indications (aseptic instability and periprosthetic fracture). Hospital data on 168 patients having undergone revision THA between 2010 and 2018 at the Department of Traumatology, Sestre milosrdnice University Hospital Centre from Zagreb were analyzed. Financial data were collected from the Hospital Information System. Financial analysis included total cost per patient, Croatian Health Insurance Fund reimbursements, cost of implants, and length of hospital stay. The difference between the mean total cost per patient and the mean Croatian Health Insurance Fund reimbursements was -262.83 € (-6.08%) for aseptic instability, -1694.94 € (-17.25%) for infection and -916.49 € (-17.33%) for periprosthetic fracture. The Croatian Health Insurance Fund does not recognize differences in the cost of revision THA for aseptic instability, infection and periprosthetic fracture. Health insurance reimbursement is inadequate for centers that offer revision hip surgery.

EIGHTY YEARS OF ELECTROCONVULSIVE THERAPY IN CROATIA AND IN SESTRE MILOSRDNICE UNIVERSITY HOSPITAL CENTRE.

SummaryIn 1937, Ugo Cerletti and Lucio Bini performed electroconvulsive treatment (ECT) in Rome for the first time. That was the time when different types of ‘shock therapy’ were performed; beside ECT, insulin therapies, cardiazol shock therapy, etc. were also performed. In 1938, Cerletti and Bini reported the results of ECT. Since then, this method has spread rapidly to a large number of countries. As early as 1940, just two years after the results of the ECT had been published, it was also introduced in Croatia, at Sestre milosrdnice Hospital, for the first time in our hospital and in the then state of Yugoslavia. Since 1960, again the first in Croatia and the state, we performed ECT in general anesthesia and continued it down to the present, with a single time brake.

Management of Patients with Cardiac Implantable Electronic Devices Undergoing Magnetic Resonance Imaging – Proposal for Unified Hospital Protocol: Croatian Working Group on Arrhythmias and Cardiac Pacing

SUMMARYFor many years, magnetic resonance imaging (MRI) was contraindicated in patients with cardiac implantable electronic devices (CIED). Today, there is a growing amount of evidence that MRI can be performed safely in the majority of patients with CIEDs. Firstly, there are devices considered MRI conditional by manufacturers that are available on the market and secondly, there is clear evidence that even patients with MRI non-conditional devices can also undergo MRI safely. Protocols have been developed and recommendations from different cardiac and radiologic societies have been published in recent years. However, the majority of physicians are still reluctant to refer these patients to MRI. Therefore, this document is published as a joint statement of the Croatian Working Group on Arrhythmias and Cardiac Pacing and Department of Radiology, Sestre milosrdnice University Hospital Centre to guide and ease the management of patients with CIED undergoing MRI. Also, we propose a unified protocol and checklist that could be used in Croatian hospitals.

CHARACTERISTICS AND PROGNOSIS OF TRIPLE-NEGATIVE BREAST CANCER PATIENTS: A CROATIAN SINGLE INstitution RETROSPECTIVE COHORT STUDY.

SUMMARYTriple-negative breast cancer (TNBC) occurs in around one-sixth of all breast cancer (BC) patients, with the most aggressive behavior and worst prognosis of all BC subtypes. It is a heterogeneous disease, with specific molecular characteristics and natural dynamics of early recurrence and fast progression. Due to the lack of biomarkers or any valid treatment targets, it can only be treated with classic cytotoxic chemotherapy. We analyzed a cohort of 152 patients, median age 58 years, diagnosed with and treated for early stage TNBC at the University Hospital for Tumors, Sestre milosrdnice University Hospital Centre, Zagreb, Croatia, during the 2009-2012 period. Patients were treated with primary surgical approach, adjuvant chemotherapy and adjuvant irradiation. We observed a relatively large proportion of locally advanced TNBC at diagnosis, with large tumor size and nodal involvement, with high grade and high proliferation index Ki67. Patient age, tumor size and lymph node involvement, as expected, were significant and clinically most important prognostic factors for 5-year disease-free survival (67%; 95% CI 60%-75%) and overall absolute survival rate (74%; 95% CI 66%-81%).

TWENTY-YEAR EXPERIENCE WITH LARGE LOOP EXCISION OF THE TRANSFORMATION ZONE AT SESTRE MILOSRDNICE UNIVERSITY HOSPITAL CENTRE.

SUMMARYThe 20-year experience with large loop excision of the transformation zone (LLETZ) at Gynecologic Oncology Unit, Department of Gynecology and Obstetrics, Sestre milosrdnice University Hospital Centre from Zagreb is presented. This retrospective observational study included 1407 women with cervical dysplasia treated by LLETZ technique during the 1995-2016 period. LLETZ was most commonly performed in the 25-35 age group (51%), followed by the 36-45 age group (22%), and least frequently in the >65 age group (2%). Histopathologic results lower than high-grade squamous intraepithelial lesion were found in 23% and high grade squamous intraepithelial lesion or worse findings in 77% of patients. Positive margin as a sign of possible residual dysplasia was found in 25% of cones, 80% of which included endocervical positive margin. Cervical canal biopsy result was positive in 18% of cases. Accurate colposcopy and its findings can help avoid overtreatment, the rate of which was higher than expected in our retrospective study. Long-term follow up is an imperative for proper assessment of the procedure success. This method is the best choice for complete disease removal without unnecessary overtreatment, but it requires continuous education and training of the whole team.

ACTIVE MIDDLE EAR VIBRANT SOUNDBRIDGE SOUND IMPLANT.

SUMMARYThe Vibrant Soundbridge represents a new approach to hearing improvement in the form of active implantable middle ear hearing device. Unlike conventional acoustic hearing aids, which increase the volume of sound that goes to the eardrum, the Vibrant Soundbridge bypasses the ear canal and eardrum by directly vibrating the small bones in the middle ear. Because of its design, no portion of the device is placed in the ear canal itself. The Vibrant Soundbridge has been approved by the FDA as a safe and effective treatment option for adults with moderate to severe sensorineural, conductive or mixed hearing losses who desire an alternative to the acoustic hearing aids, for better hearing. The paper presents a review of the active middle ear implant Vibrant Soundbridge, which has been also implanted at the Department of Otorhinolaryngology and Head and Neck Surgery, Sestre milosrdnice University Hospital Center, which is the Referral Center for Cochlear Implantation and Surgery of Hearing Impairment and Deafness of the Ministry of Health, Republic of Croatia.

20 Years of the Reference Center for Prostate Tumors of the Ministry Of Health at the Department of Urology in Sestre Milosrdnice University Hospital Center.

The Department of Urology at the Sestre milosrdnice University Hospital Center is the oldest urological institution in the Republic of Croatia and this part of Europe. Today, the Department is a modern tertiary healthcare institution, where the most complex methods of urological practice are performed using modern medical devices and highly sophisticated technology. In 2011, our urology specialist education program was certified by the European Board of Urology (EBU) as the only one of its kind in Croatia. The program was recertified in 2017. The Department runs a program for the early detection of prostate cancer and performs more than 240 radical prostatectomies annually, which is the highest number of such interventions in Croatia. The aim of this study is to present the work and the activities of the Reference Center for Prostate Tumors of the Ministry of Health at the Department of Urology in Sestre milosrdnice University Hospital Center over the last 20 years. The database of the Reference Center for Prostate Tumors of the Ministry of Health at the Department of Urology in Sestre milosrdnice University Hospital Center was reviewed. During the twenty-year period, approximately 15,000 prostate interventions were performed due to benign and malignant diseases. Of this, 7,374 transrectal ultrasound guided prostate biopsies, 2,632 radical prostatectomies with open retropubic access, 3,988 transurethral prostate resections and 1,097 open suprapubic adenomectomies were performed. With the achieved scientific and professional results in monitoring, studying and improving the prevention, diagnosis and therapy of prostate tumors, as well as with the professional conditions and personnel, the Department of Urology in Sestre milosrdnice University Hospital Center truly justifies the title of the Reference Center for Prostate Tumors of the Ministry of Health of the Republic of Croatia awarded to it in 1998.

History of Urology at the Sestre Milosrdnice University Hospital Center.

The history of Croatian urology clearly shows its affiliation to the medical and civilizational circle of the Western world. The Department of Urology at the Sestre milosrdnice University Hospital Center is the oldest urology institution in the Republic of Croatia. The Department was established in 1894, when the new Sestre milosrdnice Hospital was open in Vinogradska cesta in Zagreb. It was then that doctor Dragutin Mašek founded the so-called III Department, which, in addition to treating urology patients, also treated patients with conditions of the ear, nose and throat, eye diseases and dermatologic conditions. Dragutin Mašek had already realized that medicine would soon be divided into fields and had assigned younger doctors joining the III Department to specific fields. As a result, urology was given to Aleksandar Blašković, who founded the first independent department of urology in Croatia in 1926. In 1927, he was appointed Professor of urology at the Zagreb School of Medicine, where he established the first department of urology and was giving lectures and practicals. Under his leadership, the Department of Urology was given the status of a Clinic, a teach-ing department, the first of its kind in Croatia. Owing to all his activities in the field of urology, the history remembers him as the "father of modern Croatian urology". Over the course of the following years, department chairs had changed, but luckily for the patients, approach to work had not. Conscientiousness, trust, competence and charity. After all, charity is the idea that the hospital carries even in its name, after the Sisters of Charity who had founded it. In all the decades, the Department of Urology has been following global development paths, objectively legging behind top facilities in the world by only a few years. Overall professional and scientific urology activities culminated in 1998, when the Clinic became the Reference Center of the Ministry of Health of the Republic of Croatia for prostate cancer, and in 2011, when it became the European Board of Urology Certified Center. All that has been achieved could not have been done without wholehearted help and cooperation of the nurses, as well as every other department employee from the beginnings of urology until today. Despite its rich history, the Department does not rest on laurels. Today, it is a modern urology department together with its European role models.
