Abstract
Objectives The present paper aims to review important contemporary information about VTE risk in endogenous and exogenous CS, as a substantial discrepancy exists between the results of a recent meta-analysis confirming the increased risk for VTE and the absence of CS in VTE guidelines. Methods An extensive search of relevant databases (e.g. PubMed, Google Scholar, and Scopus) was performed in order to establish the interconnectedness of the following terms: Cushing's syndrome, venous thromboembolism, deep vein thrombosis, pulmonary embolism. Results The analysis demonstrated that patients with CS have about ten times the risk for VTE, particularly during the first year following the diagnosis of CS. Oral glucocorticoid users (with iatrogenic CS) have a 3-fold increase in risk of VTE in comparison with non-users. The most recent 2019 meta-analysis encompassed 7142 patients with endogenous CS (including Cushing's disease) undergoing transsphenoidal surgery or adrenalectomy, and their risk of unprovoked VTE was almost 18 times higher in comparison with a healthy population. Conclusion Over the past 50 years considerable evidence of increased VTE risk in CS has been accumulated. It pertains to both endogenous and exogenous type of CS and has been confirmed in the vast majority, if not all the available studies, including meta-analyses. Nevertheless, official CS guidelines make no mention of CS as a VTE risk factor, even though it is important that not only physicians who treat CS, but also physicians who manage patients with suspected VTE be aware of increased VTE risk.

Abstract
The aim of the study is detection of the recurrences and metastases of colorectal carcinomas using (111)In labelled antibodies B72.3 in 14 patients. With tomography, we can access better distinction of tumour in comparison to other structures and estimation of its size. Other imaging methods (CT, US) have advantage in detection of liver metastases, while immunoscintigraphy is more specific for the assessment of malignant abdominal tumours and extrahepatic metastases. The first results point out that Oncoscint CR-103 can be useful in diagnosis of recurrences and metastases of colorectal carcinoma, viability assessment after radiotherapy and in the choice of the adequate surgical treatment in dependence of the spread of the disease.

Abstract
The aim is the assessment of the HP infection in stomach using breath test and comparison to other diagnostic methods, as well as following up the effect of therapy. In 83 patients with digestive discomfort rapid urease test, histology and breath test were performed, while in 25 patients with proven HP infection the effect of therapy was followed up using breath test and clinical findings. For rapid urease test and histology, samples were taken from antral mucosa. Breath test was performed after per oral administration of the capsule of 14C- urea (37 kBq) (Izotop, Hungary and Laboratory for radioactive isotopes, Vinca) which, in the presence of Helicobacter pylori breaks up to 14CO2 and NH3. Radioactivity was measured by beta counter in the exhaled air fasting and 30 minutes after ingestion of the capsule. According to our results, the rise of activity over 100% was considered positive. From 83 patients, 58 were breath test was positive, 24 negative and one equivocal. Fast urease test was in 54 positive, in 29 negative while histology was in 57 postitive and 26 negative. Findings of the breath and urease tests were in accordance in 93% patients while breath test and histology in 98% patients. During follow up of the therapeutic effects, breath test and clinical findings were in accordance in 98% patients. Breath test can be useful in diagnosis but is a method of choice in following up the patients after therapy for H. pylori infection, because it is non-invasive, fast and precise.

Abstract
The aim of the study is detection of the abdominal infective foci using 99mTc-ciprofloxacin, radiopharmaceutical supposed to distuinguish inflammation from infection. Twenty one patient was investigated. There were 11 true positive findings, 7 true negative, two were false negative, while 1 was false positive. Sensitivity of the method was 79% and specificity 91%. According to our results, scintigraphy with infecton is a useful method for detection and assessment of exact localization of deep seated bacterial infections, which might be useful for (differential) diagnosis, surgical treatment in due time as well as monitoring of the treatment of conservative therapy.

Abstract
The aim of this study was to determine the long-term functional outcome of kidneys in children with urolithiasis treated by means of extracorporeal shock wave lithotripsy (ESWL). The effectiveness and safety of this method in the management of pediatric urinary stone disease was also studied. This prospective study enrolled 84 children, 33 boys (age: 9.1 +/- 3.8 yrs) and 51 girls (age: 9.6 +/- 3.9 yrs), with urolithiasis who were treated using a second-generation "Siemens" Lithostar lithotriptor, in the period between 1988 and 1998. Dynamic kidney scintigraphy using (99 m)Tc-DTPA was done prior to, immediately following ESWL treatment, three months later, and again after an observation period of 12 - 67 months (38 +/- 13 months). Immediate fragmentation rate was 90 %, while the calculus clearance rate was 61 %. Glomerular filtration rate (GFR), measured by clearance of (99 m)Tc-DTPA, immediately after an ESWL treatment of 107 +/- 6 ml/min was significantly lower compared to the pretreatment value of 118 +/- 7 ml/min, but returned three months later to 121 +/- 6 ml/min, and to 131 +/- 10 ml/min at the end of the observation period. A separate analysis was performed on three groups of patients treated by ESWL: with acute calculous disease, chronic calculous disease, and chronic calculous with partial stasis. ESWL treatment in children with acute obstruction was associated with an immediate increase in GFR; however, in chronic calculous disease a decrease in GFR was found. A return of GFR to the pretreatment level was observed at the three-month control in these patients. In patients with acute stone obstruction, at 3 and 12 - 67 months after ESWL treatment, GFR of the treated kidney was found to be significantly increased compared to the pretreatment level. In contrast, in children with chronic calculous disease this increase was modest. This study has demonstrated ESWL to be an effective treatment option for urinary calculi management, which can be safely performed in a pediatric population without long-term effects on the growing kidneys.

Abstract
The aim of the study was estimation of the relation between the gallbladder (GB) motility function and the presence and quantity of enterogastric reflux (EGR). We investigated 172 patients with: physiological GB function (filling and emptying)(FGB), impaired GB function (prolonged filling and ejection fraction < 45%) and afunctional gallbladder (AGB)(without visualization). The study was performed during 90 min (1 f/min) after i.v. application of 185 MB 99mTc-dietil IDA. After 30 min. test meal was given while at the end stomach was marked. According to the parameters from time activity curves over stomach and hepatobiliary system, the index of ERG was calculated, while GB filling and ejection fraction were estimated from the GB time/activity curve. We can conclude that EGR occurs more frequently in the patients with afunctional GB in comparison to those with functional and decreased motor function. Also, EGR quantity is in correlation with the impairment of the GB function.

Abstract
A case of ESWL treatment, as monotherapy, of a 'stoned' ureteral stent in a 12-year-old boy was described. Two years previously, the patient had pyelolithotomy with staghorn stone removal, and double-J stent was left indwelling intraoperatively. The patient was lost for follow-up for 2 years, when he had multiple stone formation adherent to the whole length of the stent. Four ESWL sessions were required before the stent was freed for removal.

Abstract
Carcinoembryonic antigen (CEA) and tissue polypeptide antigen (TPA) levels in serum and urine from 25 patients with bladder cancer and 42 patients with cancer of the renal pelvis/ureter have been evaluated as an aid for clinical diagnosis of urothelial cancer. The tumour CEA content varied markedly, from values obtained in normal urothelium up to 822 and 7306 ng/g wet tissue in cancer of the renal pelvis/ureter and bladder cancer, respectively. Serum and urine CEA levels were found not to correlate with the tumour CEA content. Serum CEA levels were found increased over 5 microg/L in up to 16% of bladder cancer patients, but only in 4.8% in renal pelvis/ureter cancer. Urine of cancer patients contained usually normal CEA levels. Increased serum TPA levels were found in 48% and 35.7% of patients with bladder cancer and cancer of renal pelvis/ureter, respectively. Urine TPA levels were significantly increased in both, patients with bladder cancer (p<0.001) and cancer of renal pelvis/ureter (p<0.01). The median values of urine TPA were 59, 1095 and 1325 U/L, in controls, patients with bladder cancer and cancer of renal pelvis/ureter, respectively. However, considering previously described increase of TPA in inflammatory diseases of urinary tract and in renal failure patients, results of urinary TPA obtained in the diagnostic workup of urothelial cancer should be cautiously interpreted. This study shows that serum and urine levels of CEA and TPA have no diagnostic accuracy required for clinical diagnosis of urothelial cancer.

Abstract
BACKGROUND The purpose of this study was to investigate bladder function parameters by means of quantitative radionuclide cystography (QRC) in anxious, irritable children with unstable bladder. METHODS Quantitative radionuclide cystography was performed in 18 children aged between 8 and 12 years, without evidence of neurologic and nephrologic disorders. Findings were compared with those obtained in 10 healthy children aged between 7 and 10 years. The dynamics of the bladder emptying were studied after intravenous injection of 37 MBq/10 kg b.w. 99mTc-diethylenetriaminepentaacetic acid (DTPA) in the posterior views. Images of 90 frames every 2 sec. were stored in the 64 x 64 computer matrix during voiding. The patients voided into a container and the volumes were measured. RESULTS The parameters evaluated were: functional bladder capacity (ml)--FBC, expected bladder capacity (ml)--EBC, percentage of EBC (%), voided urine volume (ml)--VV, residual urine (ml)--RU, voiding time (sec)--VT, average flow rate (ml/sec)--AFR and peak flow rate (ml/sec)--PFR. There was a statistically significant difference between controls and children with unstable bladder in the following parameters: FBC 288 +/- 33 vs. 244 +/- 27 ml (p < 0.001), % of EBC 99 +/- 6 vs. 82 +/- 6% (p < 0.0001), VV 265 +/- 37 vs. 202 +/- 35 ml (p < 0.0001), RU 22 +/- 11 vs. 48 +/- 19 ml (p < 0.007), AFR 13 +/- 5 ml/sec vs. 9 +/- 4 ml/sec. (p < 0.01) and PFR 19 +/- 2 vs. 13 +/- 3 ml/s (p < 0.0001), respectively. The VT obtained from the control group of 23 +/- 9 s did not differ significantly from the value of children with unstable bladder of 28 +/- 14 s. CONCLUSION The results show that quantitative radionuclide cystography is a simple, noninvasive method, which allows a good separation of patients with unstable bladder from the children with normal voiding pattern.

Abstract
Sixty patients with previously documented autosomal dominant polycystic kidney disease (ADPKD) were investigated using dynamic kidney scintigraphy with 99mTc-diethylenetriaminepentaacetic acid (DTPA). Patients were subdivided in respect of glomerular filtration rate (GFR) as follows: PKD I group (normal GFR), PKD II group (moderately reduced GFR), and PKD III (severely reduced GFR). Scintigraphic features, time activity curves, excretion parameters, global and individual kidney functions were analyzed. Because of GFR dependent sensitivity, in advanced renal failure being only 0.1, and low reproducibility (11% intraobserver, 22% interobserver), 99mTc-DTPA dynamic kidney scintigraphy cannot be generally recommended for the diagnosis of ADPKD, but has to become a routine method for functional evaluation of both global and individual renal functions, as well as degree of excretion disturbances in ADPKD patients.
