Phytotherapeutic compounds are largely used in the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) due to low side-effect profiles and costs, high level ...of acceptance by patients and a low rate of dropout. Here, we aimed to analyze all available evidence on the role of Cucurbita pepo in the treatment of LUTS-BPH.
In May 2016 a systematic search was carried out thorough National Library of Medicine Pubmed, Scopus database and the ISI Web of Knowledge official website in order to identify all published studies on Cucurbita pepo and BPH. The following search strings were used: "Cucurbita pepo" OR "pumpkin seed" AND "prostate"; "Cucurbita pepo" AND "antiandrogen" OR "antiproliferative" OR "anti-inflammatory" OR "antioxidant activities"; "cucurbita pepo" OR "pumpkin seed" AND "LUTS" AND "symptoms improvement" OR "quality of life". We consider for the present analysis only studies related to LUTS-BPH.
Among all 670 screened, 16 were related to LUTSBPH and finally analyzed. Among all, ten of them were performed in "in vitro setting" showing anti-inflammatory and antiandrogen effect, and a reduction in prostate growth and detrusor activity, while six were clinical studies. In all studies an improvement in International Prostatic Symptoms Score (IPSS) and uroflowmetry parameters has been reported. In 4 studies, an improvement in quality of life has been reported.
On the basis of our narrative review, the use of Cucurbita pepo in the management of patients affected by LUTS-BPH seems to be useful for improving symptoms and quality of life. However, future clinical trials are requested to confirm these promising results.
Bilateral posterior dislocation of the glenohumeral joint is an uncommon event, that can be missed at the initial presentation. We report the case of a 76-year old woman, who suffered a traumatic ...bilateral posterior dislocation, that was diagnosed three months later. She underwent surgical treatment on both shoulders in a single stage. Since the right shoulder showed a defect of the articular surface >50%, a reverse shoulder arthroplasty was performed on this side. The resected portion of the humeral head was retrieved and used as osteochondral graft to fill the reverse Hill-Sachs lesion of the left shoulder.
At 18-month follow up, the patient was pain-free and had recovered excellent shoulder function on both sides: Constant score was 79 for the right shoulder and 88 for the left one. X-rays showed a grade 1 scapular notch of the right reverse prosthesis and good incorporation of the graft in the left shoulder, with no evidence of degenerative joint changes.
Neglected posterior dislocations of the shoulder can be surgically treated by replacement or reconstruction. In case of bilateral injuries, the surgeon should carefully evaluate the pathoanatomy of both glenohumeral joints in order to choose and plan the most suitable procedure. If shoulder replacement is required on one side, the resected portion of the humeral head can be used as osteochondral autograft for a reconstruction procedure in the opposite side. The choice is influenced by several variables and decision-making might be challenging.
Prostate carcinoma (PCa) is one of the leading causes of cancer-related death in males, but biomarkers for the prognosis are rare. Capillary morphogenesis gene 2 (CMG2) is a modulator of ...extracellular matrix remodeling during angiogenesis. Four isoforms of CMG2 have been described so far, one secreted in the serum as soluble CMG2 (sCMG2). The aim of this study was to evaluate the sCMG2 serum concentrations in 179 PCa patients and 163 age-matched control subjects by ELISA and correlate it to clinical and demographic parameters. We observed that sCMG2 concentration is increased in the serum of PCa patients with metastases, while no significant differences in the concentrations were detected between the control subjects and patients with localized PCa. Furthermore, elevated sCMG2 concentrations were significantly associated with the highest T stage. Increased sCMG2 serum concentrations tended to be associated with a worsened overall and disease-specific survival of the PCa patients. In conclusion, sCMG2 may be an interesting additive biomarker for the prediction of the progression of PCa and the patients' outcome.
Objective: The aim of this study is to compare the outcomes of right- and left-sided live donor nephrectomies using the inverted kidney transplantation technique for right live donor nephrectomy on ...transplantation. Material and methods: A retrospective review was done for the cases of live donor nephrectomy, either as open donor nephrectomy or laparoscopic donor nephrectomy between 2004 and 2019. Inverted kidney transplantation was used with right-sided grafts. The variables of the right- and left-sided live donor nephrectomies were compared. Results: There were 202 live donor nephrectomies including 71 (35.1%) open donor nephrectomies and 131 (64.9%) laparoscopic donor nephrectomies with 4 cases of conversion to open donor nephrectomy. There were 119 (58.9%) right-sided and 83 (41.1%) left-sided live donor nephrectomies with insignificantly different mean operative time (123 and 127 minutes; P=.09), mean warm ischemia time (82.3 and 84.5 seconds; P=.32), and mean blood loss (73 and 78 mL; P=.18), respectively. Inverted kidney transplantation was performed for 86% of grafts from right live donor nephrectomies. Discharge from hospital was on an average of 4.3 days postoperatively. There were only 3 complications (1 in right live donor nephrectomy and 2 in left live donor nephrectomies) with grade 2 according to Clavien–Dindo Classification. Incidence of delayed graft function (P=.09), transplant vein thrombosis (1 case in each group), 1-year graft survival rate (93.2% vs. 94.8%; P=.12), and 1-year serum creatinine levels (1.4 ± 0.3 vs. 1.3 ± 0.2; P=.09) revealed statistically insignificant differences. Conclusion: Regardless of the surgical technique, the right live donor nephrectomy seems to be technically as safe as the left live donor nephrectomy for both the donors and the recipients. Using inverted kidney transplantation provided convenient extensions of graft’s vessels to full length with no significant increased incidence of vascular thrombosis
Purpose: The aim of this study was to evaluate the clinical relevance of the presence of disseminated tumor cells in peripheral
blood (so-called circulating tumor cells) for renal cell carcinoma ...patients.
Methods: Two hundred thirty-three peripheral blood samples from 154 renal cell carcinoma patients were investigated for the
presence of disseminated tumor cells by autoMACS technique and immunocytochemical staining of cytokeratin. The frequency of
circulating tumor cells was analyzed statistically for correlation with relevant clinical data.
Results: Two kinds of tumor cells were detected: those with expression of cytokeratin 8/18 (CK+) and cells without a detectable
cytokeratin expression, which we called large blue-stained cells with a tumorlike morphology. After following the CD45 autoMACS
depletion protocol, we identified circulating tumor cells in 96 (41%) of 233 peripheral blood samples, which originated from
81 (53%) of 154 renal cell carcinoma patients. A significant correlation between the detection of circulating tumor cells
and positive lymph node status ( P < 0.001; χ 2 test) and the presence of synchronous metastases at the time of primary tumor resection ( P = 0.014; χ 2 test) was found. In a multivariate Cox's regression hazard model, presence of CK+ circulating tumor cells was significantly
correlated with poor overall survival for renal cell carcinoma patients (relative risk, 2.3; P = 0.048).
Conclusions: The presence of circulating tumor cells correlated to lymph node status and presence of synchronous metastases
in renal cell carcinoma. It is important to evaluate CK+ and blue-stained tumor cells together to determine the role of circulating
tumor cells in tumor behavior and disease progression. Detection of CK+ circulating tumor cells in peripheral blood is a significant
and independent prognostic factor for renal cell carcinoma.(Cancer Epidemiol Biomarkers Prev 2009;18(8):2190–4)
OBJECTIVE
To compare the oncological outcomes of laparoscopic radical nephroureterectomy (LNU) vs open NU (ONU) for upper urinary tract transitional cell carcinoma (TCC).
PATIENTS AND METHODS
Between ...July 1999 and January 2003, we performed 70 LNUs and 70 ONUs for TCC of the upper urinary tract. ONU was reserved for patients with previous abdominal surgery or with severe cardiac and/or pulmonary problems. Demographic data, tumour staging and histological grading and rates of metastasis were recorded and compared.
RESULTS
For LNU and ONU the mean operative durations were 240 min and 190 min, respectively. The definitive pathology showed a high incidence of tumour stage pT2 G2 in both LNU and ONU groups. The median follow‐up was 60 months. In the LNU group, the 5‐year disease‐free survival (DFS) was 75%: 100% for pTa, 88% for pT1, 78% for pT2, and 35% for pT3 (P < 0.001). In the ONU group, the 5‐year DFS was 73% (LNU vs ONU, P = 0.037): 100% for pTa, 89% for pT1, 75% for pT2 and 31% for pT3 (P < 0.001).
CONCLUSION
The results of our long‐term controlled study support the use of LNU as an effective alternative to ONU in the therapy of upper urinary tract urothelial cancer.
Background/Aims: We compare conventional office blood pressure measurements with automated SPRINT-study type readings in kidney transplant recipients in order to determine the impact of the white ...coat effect in a prospective observational study. Methods: Adult patients with a functional renal transplant not dependent on dialysis were eligible. Readings were taken in the office in presence of the physician with an oscillometric method. Afterwards, readings were repeated with the patients resting alone in a quiet examination room with an automated blood pressure monitor. After 5 minutes of rest, 3 readings were taken at 1 minute intervals, with an average of these 3 readings calculated by the monitor. Results: 120 patients with an average age of 58.5±12.2 years were included. Mean time since transplantation was 7.95±6.48 years. Mean eGFR (CKD-EPI) was 48.5±18.3 ml/min. SPRINT-study type readings were significantly lower than office readings (139.01±18.45 vs. 149.00±21.02 mmHg systolic, p<0.001; 80.88±11.63 mmHg vs. 84.35±12.41 mmHg diastolic, p <0.001). Correlation analysis for many potentially influencing factors (diabetes mellitus, transplant vintage, proteinuria, age, immunosuppression, donor type) was not significant but obese women were significantly more prone to white coat hypertension. Conclusion: Automated office blood pressure measurements should be considered the method of choice in kidney transplant recipients.
Members of the urokinase-type plasminogen activator (uPA) system including uPA, its receptor uPAR and the plasminogen activator inhibitor 1 (PAI-1) play an important role in tumour invasion and ...progression in a variety of tumour types. Since the majority of clear cell renal cell carcinoma (ccRCC) shows distant metastasis at time of diagnosis or later, the interplay of uPA, uPAR and PAI-1 might be of importance in this process determining the patients' outcome.
Corresponding pairs of malignant and non-malignant renal tissue specimens were obtained from 112 ccRCC patients without distant metastasis who underwent tumour nephrectomy. Tissue extracts prepared from fresh-frozen tissue samples by detergent extraction were used for the determination of antigen levels of uPA, uPAR and PAI-1 by ELISA. Antigen levels were normalised to protein concentrations and expressed as ng per mg of total protein.
Antigen levels of uPA, uPAR, and PAI-1 correlated with each other in the malignant tissue specimens (rs=0.51-0.65; all P<0.001). Antigen levels of uPA system components were significantly higher in tissue extracts of non-organ confined tumours (pT3+4) compared to organ-confined tumours (pT1+2; all P<0.05). Significantly elevated levels of uPAR and PAI-1 were also observed in high grade ccRCC. When using median antigen levels as cut-off points, all three uPA system factors were significant predictors for disease-specific survival (DSS) in univariate Cox's regression analyses. High levels of uPA and uPAR remained independent predictors for DSS with HR=2.86 (95% CI 1.07-7.67, P=0.037) and HR=4.70 (95% CI 1.51-14.6, P=0.008), respectively, in multivariate Cox's regression analyses. A combination of high antigen levels of uPA and/or uPAR further improved the prediction of DSS in multivariate analysis (HR=14.5, 95% CI 1.88-111.1, P=0.010). Moreover, high uPA and/or uPAR levels defined a patient subgroup of high risk for tumour-related death in ccRCC patients with organ-confined disease (pT1+2) (HR=9.83, 95% CI 1.21-79.6, P=0.032).
High levels of uPA and uPAR in tumour tissue extracts are associated with a significantly shorter DSS of ccRCC patients without distant metastases.

The urinary incontinence system ATOMS (A.M.I., Austria) generates suburethral compression through its sphincter cushion. To what extent the ATOMS may lead to overactive bladder (OAB) symptoms or ...which risk factors for these symptoms exist remain unknown to date. We report on our multicentre evaluation on the prevalence, status, and therapy of OAB after ATOMS.
Between 10/09 and 01/17, a total of 361 patients received an ATOMS device in Vienna and Halle. A prerequisite for surgery was persistent male stress urinary incontinence lasting at least 6 months after the primary intervention, as well as the failure of conservative treatment. Patients with a preoperative untreated anastomotic stricture or detrusor overactivity were excluded. In addition to continence and voiding parameters, patient's age, BMI, comorbidities, and pre-treatment strategies of the underlying disease and urinary incontinence were examined. If
OAB was present, urodynamics were used for further clarification. Statistical analysis was performed with GraphPad Prism 7® (GraphPad Software, Inc., La Jolla, USA),
< 0.05 considered significant.
OAB presented 18 patients (4.9%). Regarding the degree of urinary incontinence as well as uroflowmetry, residual volume and comorbidities, patients with an OAB showed no differences compared to patients without an OAB (
< 0.05). Only previous radiotherapy or urinary incontinence surgery and urethral stricture interventions resulted in statistically significant differences based on the bivariate analysis (
= 0.030,
= 0.006,
= 0.007). The consecutive postoperative urodynamics revealed a sensory OAB in 17 patients and a low-compliance bladder in a patient with newly diagnosed insulin-dependent type II diabetes mellitus. OAB was treated with a standard dose of antimuscarinic drugs and for the low-compliance bladder with botulinum toxin type A.
OAB symptoms can occur after ATOMS implantation, but are rare and have no clear correlation to the incontinence device but rather are due to urinary incontinence-related underlying diseases and previous treatments.
