Assessing the association between global structural brain age and polygenic risk for schizophrenia in early adulthood: A recall-by-genotype study.

Neuroimaging studies consistently show advanced brain age in schizophrenia, suggesting that brain structure is often 'older' than expected at a given chronological age. Whether advanced brain age is linked to genetic liability for schizophrenia remains unclear. In this pre-registered secondary data analysis, we utilised a recall-by-genotype approach applied to a population-based subsample from the Avon Longitudinal Study of Parents and Children to assess brain age differences between young adults aged 21-24 years with relatively high (n = 96) and low (n = 93) polygenic risk for schizophrenia (SCZ-PRS). A global index of brain age (or brain-predicted age) was estimated using a publicly available machine learning model previously trained on a combination of region-wise gray-matter measures, including cortical thickness, surface area and subcortical volumes derived from T1-weighted magnetic resonance imaging (MRI) scans. We found no difference in mean brain-PAD (the difference between brain-predicted age and chronological age) between the high- and low-SCZ-PRS groups, controlling for the effects of sex and age at time of scanning (b = -.21; 95% CI -2.00, 1.58; p = .82; Cohen's d = -.034; partial R2 = .00029). These findings do not support an association between SCZ-PRS and brain-PAD based on global age-related structural brain patterns, suggesting that brain age may not be a vulnerability marker of common genetic risk for SCZ. Future studies with larger samples and multimodal brain age measures could further investigate global or localised effects of SCZ-PRS.

P53/MDM2 Complex-Based Targeted Strategies in Colon Adenocarcinoma.

In the current molecular review, we describe the mechanisms of TP53/MDM2 deregulation and their impact on the colon adenocarcinoma molecular substrate and phenotype. Among the genes that are critically altered in carcinogenesis, the TP53 tumor suppressor gene is of major importance. The TP53 gene (gene locus: 17p13.1) regulates the cell cycle by controlling the G1/S and G2/M checkpoints securing the normal sequence of cell cycle phases. Furthermore, it is involved in apoptosis programmed cell death. The gene is mutated or epigenetically altered in all epithelial malignancies, including colon adenocarcinoma. Additionally, Mouse Double Minute 2 Homolog (MDM2), a proto-oncogene (12q14.3), acts as a major negative regulator for p53 expression in the p53-MDM2 auto-regulatory pathway. MDM2 binds directly to p53 and represses its transcriptional activity, promoting p53 degradation. CONCLUSION: In colon adenocarcinoma, MDM2 oncogene overexpression directly influences p53 oncoprotein expression levels.

Brain ageing in schizophrenia: evidence from 26 international cohorts via the ENIGMA Schizophrenia consortium.

Schizophrenia (SZ) is associated with an increased risk of life-long cognitive impairments, age-related chronic disease, and premature mortality. We investigated evidence for advanced brain ageing in adult SZ patients, and whether this was associated with clinical characteristics in a prospective meta-analytic study conducted by the ENIGMA Schizophrenia Working Group. The study included data from 26 cohorts worldwide, with a total of 2803 SZ patients (mean age 34.2 years; range 18-72 years; 67% male) and 2598 healthy controls (mean age 33.8 years, range 18-73 years, 55% male). Brain-predicted age was individually estimated using a model trained on independent data based on 68 measures of cortical thickness and surface area, 7 subcortical volumes, lateral ventricular volumes and total intracranial volume, all derived from T1-weighted brain magnetic resonance imaging (MRI) scans. Deviations from a healthy brain ageing trajectory were assessed by the difference between brain-predicted age and chronological age (brain-predicted age difference [brain-PAD]). On average, SZ patients showed a higher brain-PAD of +3.55 years (95% CI: 2.91, 4.19; I2 = 57.53%) compared to controls, after adjusting for age, sex and site (Cohen's d = 0.48). Among SZ patients, brain-PAD was not associated with specific clinical characteristics (age of onset, duration of illness, symptom severity, or antipsychotic use and dose). This large-scale collaborative study suggests advanced structural brain ageing in SZ. Longitudinal studies of SZ and a range of mental and somatic health outcomes will help to further evaluate the clinical implications of increased brain-PAD and its ability to be influenced by interventions.

Risk for Arterial Thromboembolic Events (ATEs) in Patients with Advanced Urinary Tract Cancer (aUTC) Treated with First-Line Chemotherapy: Single-Center, Observational Study.

Arterial thromboembolism has been associated with cancer or its treatment. Unlike venous thromboembolism, the incidence and risk factors have not been extensively studied. Here, we investigated the incidence of arterial thromboembolic events (ATEs) in an institutional series of advanced urinary tract cancer (aUTC) treated with cytotoxic chemotherapy. The ATE definition included peripheral arterial embolism/thrombosis, ischemic stroke and coronary events. A total of 354 aUTC patients were analyzed. Most patients (95.2%) received platinum-based chemotherapy. A total of 12 patients (3.4%) suffered an ATE within a median time of 3.6 months from the start of chemotherapy. The most frequent ATE was ischemic stroke (n = 7). Two ATEs were fatal. The 6-month and 24-month incidence were 2.1% (95% confidence interval [CI]: 0.9-4.1) and 3.6% (95% CI: 1.9-6.2), respectively. Perioperative chemotherapy increased the risk for ATE by 5.55-fold. Tumors other than UTC and pure non-transitional cell carcinoma histology were also independent risk factors. No association with the type of chemotherapy was found. Overall, ATEs occur in 4.6% of aUTC patients treated with chemotherapy and represent a clinically relevant manifestation. Perioperative chemotherapy significantly increases the risk for ATE. The role of prophylaxis in high-risk groups should be prospectively studied.

Proteomic Analysis of Prostate Cancer FFPE Samples Reveals Markers of Disease Progression and Aggressiveness.

Prostate cancer (PCa) is the second most common cancer in men. Diagnosis and risk assessment are widely based on serum Prostate Specific Antigen (PSA) and biopsy, which might not represent the exact degree of PCa risk. Towards the discovery of biomarkers for better patient stratification, we performed proteomic analysis of Formalin Fixed Paraffin Embedded (FFPE) prostate tissue specimens using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Comparative analysis of 86 PCa samples among grade groups 1-5 identified 301 significantly altered proteins. Additional analysis based on biochemical recurrence (BCR; BCR+ n = 14, BCR- n = 51) revealed 197 significantly altered proteins that indicate disease persistence. Filtering the overlapping proteins of these analyses, seven proteins (NPM1, UQCRH, HSPA9, MRPL3, VCAN, SERBP1, HSPE1) had increased expression in advanced grades and in BCR+/BCR- and may play a critical role in PCa aggressiveness. Notably, all seven proteins were significantly associated with progression in Prostate Cancer Transcriptome Atles (PCTA) and NPM1NPM1, UQCRH, and VCAN were further validated in The Cancer Genome Atlas (TCGA), where they were upregulated in BCR+/BCR-. UQCRH levels were also associated with poorer 5-year survival. Our study provides valuable insights into the key regulators of PCa progression and aggressiveness. The seven selected proteins could be used for the development of risk assessment tools.

Quality of life, physical functioning, and psychosocial function among patients with achondroplasia: a targeted literature review.

PURPOSE: Achondroplasia (ACH) is the most common form of skeletal dysplasia, resulting in disproportionate short stature and medical complications. We review the literature on physical functioning, psychosocial function, and quality of life (QoL) in ACH individuals compared to average stature individuals or other short stature conditions. Studies that assess the association between these outcomes and height, limb length/lengthening surgery in ACH patients are also summarized. MATERIALS AND METHODS: PubMed/MEDLINE and Embase were searched through April 2021. Study inclusion criteria were: (1) quantitative design; (2) study population consisting solely/mainly of ACH patients; (3) reports of physical functioning, psychosocial functioning, and/or QoL. Included studies were summarized separately for pediatric and adult populations. RESULTS: Of 1664 records identified, 23 primary studies (sample size 8-437 participants) were included. Multiple tools were used across studies, including the generic PedsQL and SF-36 and height-specific QoLISSY. CONCLUSIONS: The literature demonstrates that ACH patients experience limitations in physical functioning and poorer QoL outcomes compared to average stature people across the life span. This appeared to be at least in part due to disproportionate short stature. Future research to better characterize QoL in ACH patients will assist clinicians to better evaluate the effectiveness of management programs including novel interventions.IMPLICATIONS FOR REHABILITATIONPatients with achondroplasia experience limitations in physical functioning and poorer quality of life throughout their life course when compared to average statured individuals.Psychosocial issues are also heightened in adults with achondroplasia compared to average statured peers but are observed less frequently in children and adolescents with achondroplasia.The overall impact that limb lengthening has on physical functioning and QoL remains unclear, although there is some evidence that greater height or upper limb length may lead to an improvement in these parameters.Rehabilitation professionals should regularly assess physical functioning, psychosocial wellbeing, and quality of life in individuals with achondroplasia using condition-specific tools.

ERCC1 19007 Polymorphism in Greek Patients with Advanced Urothelial Cancer Treated with Platinum-Based Chemotherapy: Effect of the Changing Treatment Paradigm: A Cohort Study by the Hellenic GU Cancer Group.

We previously showed that ERCC1 19007 C>T polymorphism was associated with cancer-specific survival (CSS) after platinum-based chemotherapy in patients with advanced urothelial cancer (aUC). We aimed to confirm this association in a different cohort of patients. Genotyping of the 19007C>T polymorphism was carried out by polymerase chain reaction (PCR) amplification and restriction fragment length polymorphism (RFLP) in 98 aUC patients, treated with platinum-based chemotherapy. Median age of the patients was 68.8, 13.3% of them were female, 90.8% had ECOG PS of 0 or 1, and 48% received cisplatin-based chemotherapy. In addition to chemotherapy, 32.7% of the patients received immunotherapy, and 19.4% vinflunine. Eighty-one patients (82.7%) were carriers of the 19007T polymorphic allele: 46 (46.9%) were heterozygotes, and 35 (35.7%) were homozygotes. The ERCC1 polymorphism was not associated with CSS, progression-free (PFS), or overall (OS) survival in the total population. Nevertheless, there was a significant interaction between the prognostic significance of ERCC1 polymorphism and the use of modern immunotherapy: the T allele was associated with worse outcome in patients who received chemotherapy only, while this association was lost in patients who received both chemotherapy and immune checkpoint inhibitors. Our study suggests that novel therapies may influence the significance of ERCC1 polymorphism in patients with aUC. Its determination may be useful in the changing treatment landscape of the disease.

Prediction of post radical nephrectomy complications based on patient comorbidity preoperatively.

OBJECTIVES: Comorbidity along with tumor and patient characteristics is taken into account when deciding for the surgical treatment of renal cell carcinoma (RCC). Comorbidity has also been used as an independent predictive factor for postoperative complications of several major urological procedures including radical nephrectomy for RCC. The aim of the present study was to objectively evaluate the association between comorbidity and postoperative complications after radical nephrectomy for RCC, using standardized systems to grade both comorbidity and severity of postoperative complications. MATERIALS AND METHODS: Clinicopathological data of 171 patients undergoing open radical nephrectomy for lesions suspected of RCC were prospectively recorded for a period of 3 years. Comorbidity was scored using the Charlson Comorbidity Index (CCI) while postoperative complications were graded according to the Clavien-Dindo system. RESULTS: Patients were predominantly males (59.1%); their age ranged from 35 to 88 years (mean ± SD: 63.6 ± 11.9 yrs) with 50.8% of them being ≤ 65 yrs. CCI ranged from 0 to 8 with the majority (85.3%) scoring ≤ 2. The procedure was uncomplicated in 57.3% cases; 10 patients suffered major (grade III/IV) complications and 4 patients died within the 40 days postoperative period. CCI correlated with the manifestation of any postoperative complication, Clavien ≥ 1, OR (95% CI): 1.47 (1.09-1.96), p = 0.011 and the occurrence of severe complications, Clavien > 2. OR (95% CI): 1.29 (1.01-1.63), p = 0.038. CONCLUSIONS: The present prospective study showed that considerable complications occur in patients with major comorbidities. CCI is easily calculated and should be incorporated in preoperative consultation especially in cases of elder patients with severe comorbidity and favorable tumor characteristics where less invasive interventions or even active surveillance could be applied.

Polycystin-1 induces activation of the PI3K/AKT/mTOR pathway and promotes angiogenesis in renal cell carcinoma.

In the present study we investigated the expression and the functional role of mechanosensitive polycystins in renal cell carcinoma (RCC). In 115 RCC patients we evaluated the protein expression of polycystin-1 (PC1), polycystin-2 (PC2), VEGF and protein components of the PI3K/Akt/mTOR pathway, which have been implicated both in RCC and polycystic kidney disease. PC1 and PC2 demonstrated reduced expression throughout the RCC tissue compared to the adjacent normal tissue. PC1 and PC2 revealed high expression when they were associated with higher grade and decreased 5-year survival respectively. PC1 and PC2 were positively correlated with p110γ subunit of PI3K and high PC1 expressing cells tended to display activation/phosphorylation of Akt. There was also a positive association between PC1 and VEGF expression, whereas PC1 augmented the tumor's microvascular network in stage IV carcinomas. In human RCC cells, functional inhibition of PC1 resulted in upregulation of the PI3K/Akt/mTOR pathway, enhanced cell proliferation and led to inhibition of cell migration. Conclusively, aberrant PC1 regulation is associated with increased angiogenesis and features of advanced disease in RCC tissues.

Proteomics Analysis of Formalin Fixed Paraffin Embedded Tissues in the Investigation of Prostate Cancer.

Prostate cancer (PCa) is one of the leading causes of death in men worldwide. The molecular features, associated with the onset and progression of the disease, are under vigorous investigation. Formalin-fixed paraffin-embedded (FFPE) tissues are valuable resources for large-scale studies; however, their application in proteomics is limited due to protein cross-linking. In this study, the adjustment of a protocol for the proteomic analysis of FFPE tissues was performed which was followed by a pilot application on FFPE PCa clinical samples to investigate whether the optimized protocol can provide biologically relevant data for the investigation of PCa. For the optimization, FFPE mouse tissues were processed using seven protein extraction protocols including combinations of homogenization methods (beads, sonication, boiling) and buffers (SDS based and urea-thiourea based). The proteome extraction efficacy was then evaluated based on protein identifications and reproducibility using SDS electrophoresis and high resolution LC-MS/MS analysis. Comparison between the FFPE and matched fresh frozen (FF) tissues, using an optimized protocol involving protein extraction with an SDS-based buffer following beads homogenization and boiling, showed a substantial overlap in protein identifications with a strong correlation in relative abundances (rs = 0.819, p < 0.001). Next, FFPE tissues (3 sections, 15 µm each per sample) from 10 patients with PCa corresponding to tumor (GS = 6 or GS ≥ 8) and adjacent benign regions were processed with the optimized protocol. Extracted proteins were analyzed by GeLC-MS/MS followed by statistical and bioinformatics analysis. Proteins significantly deregulated between PCa GS ≥ 8 and PCa GS = 6 represented extracellular matrix organization, gluconeogenesis, and phosphorylation pathways. Proteins deregulated between cancerous and adjacent benign tissues, reflected increased translation, peptide synthesis, and protein metabolism in the former, which is consistent with the literature. In conclusion, the results support the relevance of the proteomic findings in the context of PCa and the reliability of the optimized protocol for proteomics analysis of FFPE material.

Isolated corpus spongiosum injury after sexual intercourse.

Penile fractures are generally rare and underreported. The mechanism of injury is due to a rupture of the corpora cavernosa following blunt or sexual trauma to the penis when fully erect. Penile fractures usually present with a 'popping' sound with concomitant sudden swelling and ecchymosis of the penis followed by rapid detumescence. Urethral involvement occurs only in a small part of the cases. Isolated spongiosal injury after sexual intercourse is also extremely rare. The cardinal sign of urethral injury is blood at the meatus. A small laceration can be repaired by simple closure with absorbable sutures, while a complete rupture requires a more complex anastomotic repair. We report a case of a typically presenting penile fracture that was eventually proven to be an isolated corpus spongiosum injury, with no corpora cavernosa involvement.

Combined robot assisted right partial nephrectomy and cholecystectomy with single docking.

ΑBSTRACT: We report the first case of robot-assisted partial nephrectomy (RARN) and Robot assisted cholecystectomy in a 66 years old female overweight patient with organ-confined right kidney tumor identified on the investigation of gastrointestinal symptoms with a single docking. A modified position of the patient and a slight altered placement of the trocars made feasible the concomitant performance of the two operations. Total blood loss was 80 ml, operation time was 253 min and console time 187 min. The drain was removed on second post-operative day and the patient was discharged at the 3rd post-operative day. Using a single docking of the da Vinci S system, intraoperative time and cost are minimized in patients with both organ-confined kidney tumors and gall bladder stones.

Novel Concept Enabling an Old Idea: A Flexible Electrode Array to Treat Neurogenic Erectile Dysfunction.

INTRODUCTION: Many studies have shown that electrostimulation of the cavernosal nerve can induce and maintain penile erection. Based on these discoveries, neurostimulation to activate the erectile response has been considered a potential solution to treat erectile dysfunction (ED). However, despite recognized potential, this technology has not been further developed. The barrier is the complex anatomy of the human cavernous nerve, which challenges the intraoperative identification of the cavernosal nerves for electrode placement. AIM: To overcome this major barrier, we proposed a practical solution: a 2-dimensional flexible electrode array that can cover the entire plexus area, ensuring that at least 1 of the electrodes will be in optimal contact with the cavernosal nerve, without the need of intraoperative identification. The present study aims to evaluate this concept intraoperatively. METHODS: 24 patients enrolled for open radical prostatectomy were recruited. During the surgical procedures, the electrode array was positioned on the pelvic plexus (on the prostatic apex or pelvic wall) and electrical stimulation was applied to induce penile erection. Penile erectile response was assessed by (i) visual change of penile tumescence and (ii) by a penile plethysmograph system. MAIN OUTCOME MEASURE: Ability and success rate of evoking penile response were measured by applying electrical stimulation using the developed electrode array. RESULTS: Electrical stimulation produced immediate penile response in all cases when tested before (on prostatic apex) or after prostate removal (on pelvic wall). Clear visual penile engorgement was observed in 75% of the cases, whereas 25% showed minimal to moderate penile tumescence. As expected, patients with lower International Index of Erectile Function-5 score presented a reduced response, whereas stimulation before prostate removal showed greater response than following removal. Interestingly, erectile response was potentiated by bilateral stimulation (circumference increase [mm]: 2.7 ± 1.02 vs. 8.2 ± 1.9, P = .01). CLINICAL IMPLICATIONS: These data bring sufficient proof of concept of a conceivable novel medical implant for the treatment of ED caused by mechanical nerve injury, such as prostatectomy and spinal cord injury. STRENGTH & LIMITATIONS: This is the first approach that can ensure the optimal site stimulation of the erectogenic neuronal path within the lower pelvic area and overcome the major barrier of individual anatomic variability. However, because this study was performed intraoperatively in an acute scenario, further studies are needed to evaluate its chronic efficacy for clinical practice. CONCLUSION: The flexible electrode array concept can ensure the electrostimulation of erectogenic neuronal path when positioned on the prostate apex or pelvic floor.

Detecting Novel Urine Biomarkers for the Early Diagnosis of Prostate Cancer: Platelet Derived Growth Factor-BB as a Possible New Target.

INTRODUCTION: Although the prostate specific antigen revolutionized the diagnosis of prostate cancer (PCa), it has its limitations. We prospectively examined the potential use of the platelet-derived growth factor-BB (PDGF-BB) as a urine biomarker for the early diagnosis of PCa. MATERIALS AND METHODS: The urine samples of 118 patients were collected after a prostatic massage and all the patients subsequently underwent ultrasound-guided transrectal biopsy. PDGF-BB was detected in the urine by enzyme-linked immunosorbent assay. RESULTS: Patients with PCa had greater levels of prostate specific antigen and PDGF-BB. Receiver operating characteristic curve analysis showed that the optimal cut-of of PDGF-BB for the prediction of PCa was 1,504.9 with a sensitivity of 60% and a specificity of 51.3%. For a 100 unit increase in PDGF-BB, the likelihood for PCa increased about 4%. CONCLUSION: PDGF-BB showed a significant predictive ability for PCa. Detection of PDGF-BB in urine with Elisa was easy and improved our diagnostic accuracy in the diagnosis of PCa.

Hyaluronic acid and hyaluronidase as possible novel urine biomarkers for the diagnosis of prostate cancer.

The goal of the study is to examine the possible use of HA (hyaluronic acid) and HAase (hyaluronidase) as novel urine biomarkers for the early diagnosis for prostate cancer (Pca). After a prostatic massage, the urine of 118 high-risk patients for Pca was collected, and the patients were submitted to ultrasound-guided transrectal biopsy. HA and HAase were detected and analyzed with Enzyme-Linked Immunosorbent Assay, and a statistical analysis of the urine levels of the two biomarkers according to the histology results was performed. HAase and HA were independently associated with Pca, and both HAase and HA showed significant predictive ability for prostate cancer. With an optimal cut-off point of 183.71 HAase had 70% sensitivity maintaining at the same time a 55.2% specificity, while the optimal cut-off point for HA was 50.13 with 65% sensitivity and 53.9% specificity. Patients with HAase more than 183.71 ng/ml had 3.67 times greater likelihood for prostate cancer and Patients with HA more than 50.13 ng/ml had 2.31 times greater likelihood for prostate cancer. The need of novel biomarkers that will improve the efficacy of PSA is urgent. HAase and HA showed significant predictive ability for prostate cancer and were independently associated with Pca, and greater levels were associated with greater odds for prostate cancer. To Our Knowledge, this is the first study referring to the detection of HAase and HA as potential urine biomarkers for the early diagnosis of Pca.

Conservative management of a bladder leiomyosarcoma in a 43-year-old patient.

Leiomyosarcoma of the bladder is an aggressive and rare tumor, with less than 200 reported cases. The treatment of bladder leiomyosarcoma is controversial although in most cases an aggressive surgical therapy is preferred. Usually, a radical cystectomy is performed, as it is considered to have a better disease-specific survival rate. A 43-year-old man presented to our Urology Department with painless macroscopic hematuria. He was submitted to transurethral resection of the tumor. The transurethral resection was complete and revealed only this small single lesion and the rest of the bladder was normal with no other lesion or suspicious lesion. The final histology revealed leiomyosarcoma of the bladder. Due to his age and the aggressiveness of the tumor after a thorough and detailed discussion with the patient a conservative management with aggressive follow up was decided. The patient a year after the diagnosis is in perfect condition without sign of a recurrence or metastastes.

Single lower calyceal percutaneous tract combined with flexible nephroscopy: A valuable treatment paradigm for staghorn stones.

INTRODUCTION: We evaluated the efficacy and safety of single lower calyceal tract combined with flexible nephroscopy for the management of staghorn renal stones by percutaneous nephrolithotomy. METHODS: The medical records of patients who underwent percutaneous nephrolithotomy for the management of staghorn stones were analyzed. We included patients aged >18 years, while patients with incomplete data and renal anatomical anomalies were excluded from the study. Stone-free rate, postoperative complications, procedure duration, fluoroscopy time, and length of hospitalization were recorded. Postoperative outcomes were evaluated by non-contrast computed tomography scan 4-6 weeks after the operation. Stone-free status was defined as the absence of residual stones >4 mm. RESULTS: The study cohort consisted of 103 consecutive patients. Stone-free rate was 65.0%. No complications were observed in 69.9% of the cases; most postoperative complications were Grade 1 (13.6%) and 2 (10.7%). Five patients (4.9%) suffered a Grade 3a complication and another patient (1.0%) suffered a Grade 3b complication. CONCLUSIONS: Percutaneous nephrolithotomy through a single lower calyceal tract combined with flexible nephroscopy can be a valuable treatment option for the treatment of staghorn calculi, providing efficacy and safety. Nevertheless, the present study is limited by both its retrospective nature and being conducted at a single centre and, thus, proper prospective studies with head-on comparisons are needed to prove or disprove the advantages and disadvantages of either approach.

Bladder cancer to patients younger than 30 years: a retrospective study and review of the literature.

OBJECTIVES: The aim of this report was to study the specific characteristics of bladder cancer in patients younger than 30 years. MATERIALS AND METHODS: Five patients with a mean age of 24 ± 2.83 years were included in the study. All patients had painless macroscopic hematuria as the first symptom. Three patients had pTa as a first diagnosis, one had pT1 and one pT2. All the patients had smoking as a risk factor and at least one additional possible risk factor. RESULTS: One patient with pTa had an aggressive course and after multiple recurrences was diagnosed with pT2 and refused to be submitted to radical cystectomy and died from the disease even though he received a multimodality treatment. The other two patients with the pTa diagnosis had no recurrence after the first TUR-BT and the patient with the pT1 diagnosis after one recurrence with a pTa histology is free of recurrence for the last 2 years. The patient diagnosed with pT2 was submitted to a radical cystectomy and an s-pouch diversion with a preservation of the genital system in order to have the ability of a future motherhood with the acceptance of course risks. CONCLUSIONS: Young patients with bladder cancer is a difficult group of patients and show more reluctance to comply to the necessary strict follow-up of the repeated urinary cytology examinations, cystoscopies and CT pyelographies. Herein, we report a retrospective study of five patients younger than 30 years with bladder cancer.

B-lymphocytic infiltration of the prostate to a patient with chronic lymphocytic leukemia. A case report.

Involvement of the prostate gland, as an early extra-nodal manifestation of a hematologic disease, or as a secondary infiltration is rare. Even rarer is the acute urinary retention due to infiltration by lymphocytes and simultaneously enlarged prostate. We present a case of a 61 years old male patient with a history of chronic lymphocytic leukemia, who was under oncological follow-up with no active treatment and had typical lower urinary tract symptoms due to benign prostatic hyperplasia and was receiving 5-alpha reductase inhibitor. After an acute urinary retention episode which was managed with a suprapubic catheter due to urethral catheter insertion failure, the patient was submitted to a transurethral prostatectomy. Histological examination revealed lymphocytic infiltration of the prostatic parenchyma by mostly small B cells. B-lymphocytic infiltration of the prostate gland, causes symptoms similar to benign prostatic hyperplasia. Acute urinary retention due to B-lymphocytic infiltration of the prostate is rare and the diagnosis is always histological and an oncological re-evaluation is necessary. The prognosis of these patients is related to the generalized disease rather than to the prostatic involvement.

Prostatic abscess in a patient with chronic granulomatous disease: a multi-disciplinary intervention.

INTRODUCTION: Chronic granulomatous disease (CGD) is a rare pathology that increases patients' susceptibility to infections, given the inability to generate oxygen radicals to fight microorganisms.In the context of CGD, primary prostatic involvement has been described only once in the past, in a pediatric patient. CASE REPORT: We report the case of a 35-year old patient with CGD presenting with persistent fever. After hospital admission, blood and urine were sent for culture and antibiotic therapy was initiated. Patient´s conditions continued to deteriorate and an aggressive antibiotic therapy was administered to treat the septic scenario. Urine culture grew a multidrug-resistant Escherichia Coli. After patient's condition improved, a CT scan was performed. The depiction showed multiple abscesses within the prostate. A rectal approach was excluded given patient's underlying disease. A TURP was performed and prostatic pathology resolved. Patient was discharged on postoperative day 14. At 6-month follow-up he hasn't experienced major infections.To the best of our knowledge, this is the first case of septic shock originating from a prostatic abscess in an adult patient with CGD. CONCLUSIONS: Aggressive medical therapy along with TURP resulted curative in our case. A multi-disciplinary approach was mandatory.
