This study investigated the influence of refugee status on the occurrence of enuresis. It was performed among school children aged 6 to 11 years and their parents in the Vukovarsko-srijemska County ...(eastern Croatia), which had many displaced persons and refugees (mostly women and children) in the 1990s due to the wars in Croatia and Bosnia and Herzegovina. A specially designed questionnaire (about the child's age and gender, the child's enuresis history and that of the parents, and data on parental refugee status in childhood) was completed by one of the parents. Adequate data were collected for 3046 children. The prevalence of enuresis among the studied children was quite low (2.3%) but the prevalence distribution according to gender, the decline by age, and the higher odds ratio for paternal enuresis were in line with the results of other studies. The prevalence of parental enuresis in childhood was higher than their children's enuresis (mothers: 5.8%, fathers: 3.6%,
< 0.001), and significantly higher among parents who had been refugees (mothers:
= 0.001, fathers:
= 0.04). Parental refugee status had no influence on the children's enuresis. The results suggest that refugee status is a risk factor for the occurrence of enuresis in childhood.
The widely used screening for prostate cancer with prostate specific antigen has resulted in identification of potentially lethal prostate cancers at a much more curable stage and has been associated ...with significant falls in prostate cancer mortality. In spite of the fact that prostate cancer is one of the deadliest malignancies in men, the advent of sensitive diagnostic testing has also resulted in detection of low risk cancers due to the high incidence of latent prostate cancer in aging men and prolonged natural history of the disease. This, in turn, has entailed the problem of cancer overdiagnosis and subsequent overtreatment. Approximately 6 times as many men will be diagnosed with the disease as will die from it. Active surveillance appeared as a response to the clearly documented risks of overdiagnosis and overtreatment of low risk prostate cancer for localized prostate cancer. It entails initial expectant management rather than immediate therapy, with 'curative-intent' treatment deferred until there is evidence that the patient is at an increased risk of disease progression. This approach attempts to balance the risks and side effects of overtreatment against the possibility of disease progression and lost opportunity for cure. A systematic literature review brings current knowledge on the subject.
Spontaneous regression of testicular germ cell tumors is a well-known phenomenon; however, the precise mechanisms of spontaneous regression are still unknown. Our study aimed to investigate ...programmed death-ligand 1 (PD-L1) expression in spontaneously regressed testicular germ cell tumors, exploring the link between the immune response and spontaneous regression. From a sample of 356 testicular germ cell tumors, we singled out 5 completely regressed and 6 partially regressed tumors. In four out of six cases with partial regression, a residual seminoma component was found, while in the remaining two cases, an embryonal carcinoma component was found. Comparisons were made with 20 pure seminomas and 20 mixed germ cell tumors (MGCTs). A semiquantitative immunohistochemical analysis of PD-L1 expression in tumor cells and intra/peritumoral lymphocytes was performed. There was no PD-L1 expression in tumors with complete regression. All partially regressed tumors showed expression in intra/peritumoral lymphocytes within the tumor remnants. Expression was significantly more frequent in pure seminomas compared to MGCTs (P = 0.004). A positive correlation was demonstrated between the seminoma component and the proportion of PD-L1 positive lymphocytes, with a Kendall Tau-b coefficient of 0.626 (P < 0.001). Tumor cells showed PD-L1 expression in three MGCTs within the embryonal carcinoma component. Our results support an immunological mechanism of spontaneous tumor regression, with the strongest potential in testicular tumors containing seminoma components. However, further research is necessary to determine the role of PD-L1 ligand more precisely in the microenvironment of spontaneously regressed tumors.
Prostatic artery embolization is a minimally invasive endovascular treatment that improves lower urinary tract symptoms in men with benign prostatic hyperplasia. Although further randomized studies ...and long-term evidence is still needed for this method to be fully incorporated into treatment guidelines for benign prostatic hyperplasia, current studies show that this method can be an effective and safe alternative in patients with a significantly enlarged prostate gland who are not good surgical candidates. Therefore, we present the theory, technical details and potential benefits of this method as we review the current evidence on prostatic artery embolization.
Changes in the diagnostic pathway for prostate cancer advised in the most recent Guidelines of the European Association of Urology bring many endeavors for everyday practice. Availability, costs and ...radiological expertise are still representing a challenge for the adoption of these guidelines in everyday clinical practice. In this article we discuss the current situation regarding these issues and future options.

Liječenja raka prostate tijekom pandemije COVID-19 pretrpjelo je, kao i u slučaju drugih bolesti, značajne promjene. Jedinstvenost ovih promjena ogleda se u činjenici da je pogođen čitav svijet i da ...su se zdravstveni sustavi, pa tako i briga za onkološke bolesnike, morali prilagoditi novonastaloj situaciji. Dostupnost zdravstvenih ustanova, liječnika i drugog zdravstvenog osoblja kao i mogućnost provođenja liječenja varirali su u čitavom svijetu ovisno o epidemiološkoj situaciji. U samom početku pandemije svi zahvati, osim najhitnijih, bili su odgođeni zbog prihvata i zbrinjavanja bolesnika s COVID-19. Taj je period pandemije za dio bolesnika obilježila odgoda liječenja raka prostate, poglavito kirurškog, čime je stvoreno veliko psihološko opterećenje i za bolesnike i za liječnike. U zemljama koje su pandemiju stavile pod kontrolu postupno popuštanje protuepidemijskih javnozdravstvenih mjera rezultiralo je normalizacijom zdravstvene skrbi i nastavkom redovitog liječenja onkoloških bolesnika.
In this prospective study we examined the utility of parameters obtained on prostate needle biopsy and prostate specific antigen-alpha(1)-antichymotripsine complex (PSA-ACT) to predict adverse ...pathologic findings after radical prostatectomy. 45 consecutive patients assigned for radical prostatectomy due to clinically localized prostate cancer were included in the study. Prostate biopsy parameters such as number of positive cores, the greatest percentage of tumor in the positive cores, Gleason score, perineural invasion, unilaterality or bilaterality of the tumor were recorded. PSA-ACT was determined using sandwich immunoassay chemiluminiscent method (Bayer, Tarrytown, New York). We analyzed relationship of preoperative PSA, PSA-ACTand quantitative biopsy parameters with final pathology after prostatectomy. Adverse findings were considered when extracapsular extension of cancer (pT3) was noted. Postoperatively, 29 (64.4%) patients were diagnosed with pT2 disease and 16 (35.6%) with pT3 disease. There was a significant difference in localized vs. locally advanced disease in number of positive biopsy cores (p<0.001), greatest percentage of tumor in the core (p=0.008), localization of the tumor (p=0.003) and perineural invasion (p=0.004). Logistic regression was used to develop a model on the multivariate level. It included number of positive cores and PSA-ACT and was significant on our cohort with the reliability of 82.22%. The combination of PSA-ACT and a large scale of biopsy parameters could be used in prediction of adverse pathologic findings after radical prostatectomy. Clinical decisions and patients counselling could be influenced by these predictors but further confirmation on a larger population is necessary.
The aim of our study was to evaluate the impact of margin positivity in clinically and pathologically localized prostate cancer (pT2) after radical prostatectomy on biochemical recurrence and time to ...adjuvant treatment. We analyzed data from 371 patients who underwent radical prostatectomy. At the mean follow up of 36 (25-54) months, impact of margin positivity in pT2 patients on prostate specific antigen (PSA) recurrence and time to introduction of adjuvant treatment was noted. Out of 371 radical prostatectomies there were 277 (74.6%) pT2 and 94 (25.4%) pT3 (locally advanced) prostate cancers. Mean age was 67.6 years, mean Gleason score 6.78, mean preoperative PSA 11.45 ng/mL. Out of 277 pT2 pts., 233 (84%) had negative (SM-) and 44 (16%) positive surgical margins (SM+). Only 3% of SM- pts. had biochemical relapse (BCR). Among pT2 patients with SM+, 18 (41%) had BCR while 26 were free of recurrence at 3 years follow up. Positive surgical margins had an adverse impact on biochemical progression free survival (3% SM- vs. 41% SM+; p<0.001). No difference was found in age, preoperative PSA, Gleason score or follow up between BCR-SM+ and BCR+SM+ patients. Mean time to PSA recurrence in surgical margin positive pT2 patients was 15.7 months. Surgical margin status pT2 disease has an impact on biochemical progression but only 41% of margine positive patients show biochemical recurrence at 3 yr follow up. Not all SM+ patients need to receive treatment after radical prostatectomy. Longer follow up should be awaited to see the impact on overall survival in this group of patients.
Only few reports validated contemporary Epstein criteria for insignificant prostate cancer, and only one being from Europe. Patients with insignificant prostate cancer should be offered active ...surveillance and spared radical treatment. In our study we tested Epstein biopsy criteria for predicting unfavorable final pathology and biochemical relapse in low risk prostate cancer patients, who were eligible for active surveillance but where treated with radical prostatectomy. Between January 2003 and January 2008, 586 patients were subjected to radical prostatectomy in our institution. Among them, 106 where eligible for active surveillance according to Epstein biopsy criteria for insignificant prostate cancer. We analyzed the presence of adverse pathological findings in the final pathohistological specimen after radical prostatectomy which excludes low risk disease. Adverse pathohistological findings were noted in 41 (38.6%) patients, who could have been offered active surveillance. During the follow up of 48 (12-72) months, biochemical relapse was noted in 6 (5.6%) patients. Although active surveillance is becoming more popular because of the long natural course of prostate cancer and fear of overtreatment of patients with indolent course of disease, both doctors and patients must be aware of potentially significant disease in this group and limitations of current preoperative criteria defining low risk patients.
This study is a case of solitary clear cell renal cell carcinoma (ccRCC) eyelid metastasis in a 66-year-old man as the first sign of a primary tumor. ccRCC usually spreads to the lungs, mediastinum, ...bones, liver, and brain, while ocular metastases are rare.
Solitary metastasis presented as a solid mass in the central third of the upper eyelid, which has been growing for 3 weeks. Treatment included tumor removal and blepharoplasty. Histopathological examination showed metastasis of clear cell renal carcinoma. A thorough examination revealed a primary tumor on the lower pole of the right kidney. A right nephrectomy was performed, and histopathology showed ccRCC. Postoperative examinations showed no signs of local or systemic disease. Sunitinib malate was administered to the patient.
The eyelid metastasis in this case was still solitary and had been discovered before the existence of the primary tumor was known. Ocular metastasis of renal carcinoma is a rare initial manifestation of the disease and therefore requires a multidisciplinary approach in the treatment of these patients.
