RESUMO

Urinary tract infections (UTIs) present a formidable challenge in the care of individuals affected by multiple sclerosis (MS). Lower urinary tract dysfunction is a prevalent issue among MS patients, predisposing them to an elevated risk of UTIs. When left untreated, UTIs can further exacerbate the already compromised quality of life in individuals with MS. The diagnosis and management of UTIs in MS patients necessitate a careful clinical evaluation. The objective of this review is to delineate preventive strategies and current and developing therapeutic approaches for preventing and treating UTIs associated with urinary dysfunction, catheterization, and upper urinary tract infections in patients with MS. Effectively addressing UTIs and urinary tract dysfunction in individuals with multiple sclerosis calls for a comprehensive, interdisciplinary approach.

RESUMO

PURPOSE: The current literature on the impact of different urinary diversions on patients' health related quality of life (HR-QoL) showed a marginally better quality of life scores of orthotopic neobladder (ONB) compared to ileal conduit (IC). The aim of this study was to update the review of all relevant published studies on the comparison between ONB and IC. MATERIALS AND METHODS: Studies were identified by searching multiple literature databases, including MEDLINE, CINAHL, the Cochrane Library, PubMed Data were synthesized using meta-analytic methods conformed to the PRISMA statement. RESULTS: The current meta-analysis was based on 18 papers that reported a HR-QoL comparison between IC and ONB using at least a validate questionnaire. Pooled effect sizes of combined QoL outcomes for IC versus ONB showed a slight, but not significant, better QoL in patients with ONB (Hedges' g = 0.150; p = 0.066). Patients with ileal ONB showed a significant better QoL than those with IC (Hedges' g = 0.278; p = 0.000); in case series with more than 65% males, ONB group showed a slight significant better QoL than IC (Hedges' g = 0.190; p = 0.024). Pooled effects sizes of all EORTC-QLQ-C30 aspects showed a significant better QoL in patients with ONB (Hedges' g = 0.400; p = 0.0000). CONCLUSIONS: This meta-analysis of not-randomized comparative studies on the impact of different types of urinary diversions on HR-QoL showed demonstrated a significant advantage of ileal ONB compared to IC in terms of HR-QoL.

RESUMO

La extracción dentaria es una de las prácticas odontológicas realizadas con mayor frecuencia, pero a corto plazo los pacientes necesitan rehabilitaciones orales para optimizar el funcionamiento del sistema estomatognático. Dado que conocer las características de la población que demanda exodoncias puede contribuir a elaborar estrategias para limitar la pérdida de piezas dentarias, nos propusimos 1) registrar las características de la población que demanda exodoncias; 2) identificar las piezas dentarias extraídas; 3) registrar las causas de exodoncia; 4) identificar patologías bucales durante la consulta para una exodoncia. Para llevarlo a cabo se seleccionaron aleatoriamente 2000 historias clínicas de pacientes que concurrieron a la Cátedra de Cirugía y Traumatología Buco Maxilofacial I de la Facultad de Odontología de la Universidad de Buenos Aires (FOUBA) y se realizaron exodoncias con anestesia local entre enero de 2012 y mayo de 2014...


Dental extraction is one of the most frequent practices in dentistry, causing necessary oral rehabilitation to ensure normal stomatognathic system function. The purpose of this study was to get to know the characteristics of the population in need of dental extraction so as to develop strategies tending to limit teeth loss. We set to 1) record the characteristics of the population on demand for dental extraction; 2) Identify teeth extracted; 3) Record cause of dental extraction; 4) Identify oral pathologies during examination for dental extraction. We selected 2000 Records of patients who attended “Cátedra de Cirugía y Traumatología Bucomaxilofacial I de la Facultad de Odontología de la Universidad de Buenos Aires, FOUBA” for dental extraction with local anesthetics in the period between January 2002 and May 2014...

RESUMO

OBJECTIVES: To identify the predictive variables affecting the outcome after radical surgery for bladder cancer by a newer statistical methodology, i.e. nonparametric combination (NPC). METHODS: A multicenter study enrolled 1,312 patients who had undergone radical cystectomy for bladder cancer in 11 Italian oncological centers from January 1982 to December 2002. A statistical analysis of their medical history and diagnostic, pathological and postoperative variables was performed using a NPC test. The patients were included in a comprehensive database with medical history and clinical and pathological data. Five-year survival was used as the dependent variable, and p values were corrected for multiplicity using a closed testing procedure. The newer nonparametric approach was used to evaluate the prognostic importance of the variables. All of the analyses were performed using routines developed in MATLAB© and the significance level was set at α = 0.05. RESULTS: A significant prognostic predictive value (p < 0.01) for tumor clinical staging, hydronephrosis, tumor pathological staging, grading, presence of concomitant carcinoma in situ, regional lymph node involvement, corpora cavernosa invasion, microvascular invasion, lymphatic invasion and prostatic stroma involvement was found. CONCLUSIONS: The NPC test could handle any type of variable (categorical and quantitative) and take into account the multivariate relation among variables. This newer methodology offers a significant contribution in biomedical studies with several endpoints and is recommended in presence of non-normal data and missing values, as well as solving high-dimensional data and problems relating to small sample sizes.

RESUMO

OBJECTIVE: It was the aim of this study to evaluate the accuracy of the measurement of tumor size comparing the objective size with that measured by preoperative cystoscopy, by preoperative ultrasound (US) and with the diameter described by the operator before the transurethral resection. PATIENTS AND METHODS: This study included 100 patients with bladder papillary endoscopic features of single or multiple neoplasms who were candidates for transurethral resection. The sizes of the same neoplasms measured during preoperative cystoscopy, preoperative US and described by the operator before the transurethral resection were evaluated. A statistical analysis of the errors of measurement was performed if compared with an objective measurement done with an ureteral catheter. RESULTS: The statistical analysis of the data shows that there are no substantial differences between the objective and subjective measurement, and therefore, the measurements reported by individual operators are reliable. On the contrary, the diameters given by preoperative cystoscopy and US differ significantly from the objective measurement. CONCLUSIONS: This study shows that the most reliable measurement is the subjective measurement made directly by the urologist in the operating room.

RESUMO

OBJECTIVES: Non-muscle-invasive bladder cancer is characterized by a high recurrence rate after primary transurethral resection. In case of bacillus Calmette-Guérin-refractory neoplasms, cystectomy is the gold standard. In this study the effects of thermochemotherapy with mitomycin C were evaluated in high-risk bladder cancer nonresponders to previous therapy. PATIENTS AND METHODS: Between January 2006 and December 2009, 30 patients were enrolled with recurrent stage carcinoma in situ, Ta and T1, grade G1 to G3 non-muscle-invasive bladder cancer refractory to chemotherapy or immunotherapy and so becoming suitable for radical cystectomy. All patients underwent endovesical thermochemotherapy: 16 patients underwent a prophylactic scheme and 14 patients underwent an ablative scheme. RESULTS: All the patients completed the study. The mean follow-up for all the patients enrolled was 14 months. Thirteen of 30 patients (43.30%) were disease free and 17 patients (56.70%) had recurrence. In the prophylactic group, 7 of 16 patients (43.75%) were disease free and 9 patients (46.25%) had tumor recurrence; no progression was observed. In the ablative group, 3 patients (17, 64%) had progression to muscle-invasive disease. Side effects were generally mild. CONCLUSIONS: Thermochemotherapy could be considered an additional tool in patients refractory to intravesical therapies before considering early cystectomy.

RESUMO

The aim of the present paper was to review findings from the most relevant studies and to evaluate the value of current chemotherapy and surgery in advanced unresectable and metastatic bladder cancer. Studies were identified by searching the MEDLINE® and PubMed® databases up to 2011 using both medical subject heading (Mesh) and a free text strategy with the name of the known individual chemotherapeutic drug and the following key words: 'muscle-invasive bladder cancer', 'chemotherapeutics agents', and 'surgery in advanced bladder cancer'. At the end of our literature research we selected 141 articles complying with the aim of the review. The results showed that it has been many years since the MVAC (methotrexate, vinblastine, adriamycin, cisplatin) regimen was first developed. The use of cisplatin-based combination chemotherapy is associated with significant toxicity and produces long-term survival in only approximately 15-20% of patients. Gemcitabine + cisplatin represents the gold standard in the treatment of metastatic bladder cancer. In conclusion, the optimal approach in the management of advanced urothelial cancer continues to evolve. Further progress relies on the expansion of research into tumor biology and an understanding of the underlying molecular 'fingerprints' that can be used to enhance diagnostic and therapeutic strategies. Cisplatin-based therapy has had the best track record thus far.

RESUMO

PURPOSE: Carcinoma in situ represents high grade anaplasia of the bladder mucosa. Intravesical immunotherapy with bacillus Calmette-Guérin is the gold standard treatment for patients with carcinoma in situ. Patients with carcinoma in situ refractory to bacillus Calmette-Guérin are candidates for major surgery such as radical cystectomy. We identified the maximum tolerated dose and the recommended dose, and evaluated the safety profile of paclitaxel-hyaluronic acid bioconjugate given by intravesical instillation to patients with carcinoma in situ refractory to bacillus Calmette-Guérin. MATERIALS AND METHODS: A total of 16 patients with carcinoma in situ refractory to bacillus Calmette-Guérin were enrolled in a phase I, open label, single institution study. A minimum of 3 eligible patients were included per dose level. Paclitaxel-hyaluronic acid solution (ONCOFID-P-B™) was administered for 6 consecutive weeks. The primary objective was to identify the maximum tolerated dose and the recommended dose. As secondary objectives the safety profile of ONCOFID-P-B, the pharmacokinetic profile after each instillation and the tumor response were also evaluated. RESULTS: No dose limiting toxicity occurred at any drug level evaluated. The plasma levels of the study drug were always below the lower limit of quantification at all tested doses after each instillation. A total of 11 adverse events were reported by 7 patients and 9 (60%) showed complete treatment response. CONCLUSIONS: Intravesical instillation of ONCOFID-P-B for carcinoma in situ refractory to bacillus Calmette-Guérin showed minimal toxicity and no systemic absorption in the first human intravesical clinical trial to our knowledge. Finally, satisfactory response rates were observed.

RESUMO

Androgens are involved in the development and progression of prostate cancer even if the mechanism is not well-recognized. For this reason androgen-deprivation therapy remains a milestone for the treatment of patients with advanced and metastatic disease and, in the last years, in conjunction with radiotherapy and surgery in locally advanced tumors. Alternative options, such as intermittent deprivation suppression, seem to be promising in terms of clinical benefits and toxicity profile. However, current therapies present side effects, such as testosterone surge with consequent clinical flare-up, metabolic syndrome and hormone-resistance, which develops after a variable number of years. Novel therapies such as LH-RH antagonists and prolonged depot LH-RH analogues have been developed in order to avoid clinical flare-up and testosterone microsurges. Novel androgen synthesis inhibitors, such as abiraterone acetate and MDV3100, have been recently discovered and tested as promising hormonal second-line agents in patients with castration-resistant prostate cancer. Finally, long-term side effects from androgen deprivation, such as osteoporosis, sarcopenic obesity and cardiovascular morbidity should be carefully monitored and properly treated.

RESUMO

INTRODUCTION: Prostatitis-like syndromes are high prevalent health problems and frequently considered by patients and physicians as strictly correlated to sports causing perineal compression. These syndromes and their relationships with sporting activities have been discussed in this report. METHODS: We reviewed peer-reviewed scientific articles published by May 2009 and searched according to the following term selection: prostatitis, pudendal nerve, sport, cycling. RESULTS: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a major healthcare burden heavily affecting patients' Quality of Life. No clear evidence of any direct etiologic relationship has been found in literature between prostatitis, either bacterial or non-bacterial, and sports activities. On the other hand, some types of sport causing perineal compression, such as cycling, can exacerbate symptoms of acute and chronic prostatitis; a temporary sport discontinuation is justified in these patients. CP/CPPS may be often caused by pudendal nerve entrapment (PNE). Prostatitis-like urogenital neuropathic pain together with voiding and sexual dysfunctions are the hallmark of PNE. A common feature is that flexion activities of the hip, such as climbing, squatting, cycling provoke or worsen urogenital pain or pelvic pain. Many of the patients with PNE are cyclists, played American football, lifted weights, or wrestled as teenagers and young adults. PNE represents the most common bicycling associated urogenital problems. CONCLUSIONS: Overall, studies show that no causal relationship has been demonstrated between prostatitis and sporting activities. Conversely, urologists should be aware that sports involving vigorous hip flexion activities or prolonged perineal compression are a potential and not an infrequent cause of uroandrological symptoms caused by pudendal nerve entrapment.

RESUMO

INTRODUCTION: Statistical data referring to sports-related traumas of the urinary tract are quite scarce; nevertheless, it is possible to draw general data on the relationship between sports and urological traumas. METHODS: Literature review of peer-reviewed articles published by May 2009. RESULTS: Urological traumas account for about 10% of all traumas, and about 13% of them is sports-related. Genitourinary traumas are among the most common cause of abdominal injuries in sports. Blunt injuries are more common than penetrating ones and renal injuries are by far the most common, followed by testicular injuries; ureters, bladder and penis injuries are much more infrequent. Considering chronic microtraumas, injuries of bulbar urethra are also common in sports that involve riding. Overall, the incidence of genitourinary trauma due to sports is low. Renal traumas in sports injuries usually consist of grade I-II lesions and usually do not require surgical treatment. Cycling is the sporting activity most commonly associated with genitourinary injuries, followed by winter sports, horse riding and contact/collision sports. Literature data suggest that significant injuries are rare also in athletes with only one testicle or kidney. General preventive measures against sport-related injuries, along with the use of protective cups for male external genitalia, are generally sufficient to reduce the incidence of urogenital trauma. CONCLUSIONS: Overall, studies show that urogenital injuries are uncommon in team and individual sports, and that most of them are low-grade injuries. Participation in sports that involve the potential for contact or collision needs to be carefully assessed in the athletes with only one testicle or kidney, even though urogenital injuries should not preclude sports participation to an appropriately informed and counseled patient. Further research is needed to acquire more knowledge on genitourinary injuries according to age, sports type and technical skill.

RESUMO

Several substances such as growth hormone (GH), erythropoietin (Epo), and anabolic steroids (AS) are improperly utilized to increase the performance of athletes. Evaluating the potential cancer risk associated with doping agents is difficult since these drugs are often used at very high doses and in combination with other licit or illicit drugs. The GH, via its mediator, the insulin-like growth factor 1 (IGF-1), is involved in the development and progression of cancer. Animal studies suggested that high levels of GH/IGF-1 increase progression of androgen-independent prostate cancer. Clinical data regarding prostate cancer are mostly based on epidemiological studies or indirect data such as IGF-1 high levels in patients with prostate cancer. Even if experimental studies showed a correlation between Epo and cancer, no clinical data are currently available on cancer development related to Epo as a doping agent. Androgens are involved in prostate carcinogenesis modulating genes that regulate cell proliferation, apoptosis and angiogenesis. Most information on AS is anecdotal (case reports on prostate, kidney and testicular cancers). Prospective epidemiologic studies failed to support the hypothesis that circulating androgens are positively associated with prostate cancer risk. Currently, clinical and epidemiological studies supporting association between doping and urological neoplasias are not available. Nowadays, exposure to doping agents starts more prematurely with a consequent longer exposition period; drugs are often used at very high doses and in combination with other licit or illicit drugs. Due to all these elements it is impossible to predict all the side effects, including cancer; more detailed studies are therefore necessary.

RESUMO

Bladder cancer is a heterogeneous disease: approximately 75% of its forms are non muscle invasive neoplasms. Standard treatment for non muscle invasive bladder cancer (NMIBC) consists of complete transurethral resection (TURB) of all visible lesions. Recurrence rates following TURB and intravesical chemoprophylaxis seem to decrease to 25-50% in 2 years of follow-up. The aim of the present paper is to review findings from the most relevant studies and evaluate the potentials of mitomycin C (MMC) in the treatment of non muscle invasive bladder cancer. Studies were identified by searching MEDLINE(R) and Pubmed(R) databases up to 2010 using both medical subject heading (Mesh) and a free text strategy with the name of known individual chemotherapeutic drug and the following key words: "non muscle-invasive bladder cancer", "intravesical therapy", "Mitomycin C", "Device Therapy". At the end of our research in literature we selected 66 articles. From literature is clear that in case of low or intermediate risk superficial bladder cancer, MMC is one of the most used agents with limited side effects. In fact MMC has a high molecular weight and is relatively hydrophobic, resulting in less sistemic absorption. Regimens are based on weekly instillations but despite many studies there is not universal consensus on timing and duration of therapy. MMC early istillation seems effective in preventing tumour recurrence in low risk non muscle invasive neoplasms. MMC maintenance chemotherapy continue to be considered effective in reducing tumour recurrence rate in low and intermediate risk tumours. It is known in literature that the lack of response to intravesical chemotherapy in patients with non muscle invasive bladder cancer is due to two factors: lack of sensitivity of the neoplasm to intravesical chemotherapy and inadequate drug delivery to the tumour. In order to resolve these limitations in the last years MMC, in many centers, is used with device assisted therapies or with new administration scheme.

RESUMO

The formulation of proper evaluation criteria after superficial bladder cancer therapy poses several methodological problems that are often peculiar to the disease. The Achilles' heel of many trials is possibly found in the criteria used in the evaluation of the trial's outcome. As a consequence, total agreement regarding the criteria for response and the evaluation of response is needed. The adoption of standard response criteria should be given high priority. Uniform criteria of response should be chosen because they meet standards of reliability and statistical validity. Thus, the criteria must be reproducible and correlate with some measures of patient benefit such as quantity and quality of survival. A proposal for standardization in superficial bladder cancer clinical trials is presented based upon the current knowledge of methodology used for conducting clinical trials and upon the experience coming from clinical research groups.

RESUMO

Oncology-applied hyperthermia is a very old form of therapy. In recent years hyperthermia has been investigated with the aim of improving the treatment for non-muscle invasive bladder cancer to prevent relapse and disease progression, in association with mitomycin-C, a well-known chemotherapeutic agent, to enhance its effect. Target patients are those with non-muscle invasive transitional cell carcinoma, showing medium (Ta-T1, G1-2, multifocal, diameter >3 cm) or high (T1, G3, multifocal or rapidly relapsing, CIS) risk for recurrence or progression. The treatment may be prophylactic following tumor eradication, or ablative when tumor cannot be otherwise eradicated. Several studies have shown the benefits of thermochemotherapy with lower risk for relapse than other treatment options, and 66-80% complete responses following ablative treatment. This association of treatments has a synergic therapeutic effect, higher than administering hyperthermia and drug therapy as single treatment.

RESUMO

Bladder cancer is among the top eight most frequent cancers. Its natural history is related to a combination of factors that impact on its aggressiveness. Cystoscopy and urine cytology are the currently used techniques for the diagnosis and surveillance of non-invasive bladder tumors. The sensitivity of urine cytology for diagnosis is not high, particularly in low-grade tumors. The combination of voided urine cytology and new diagnostic urine tests would be ideal for the diagnosis and follow-up of bladder cancer. However, in order to have some clinical utility, new diagnostic and/or prognostic markers should achieve better predictive capacity that the currently used diagnostic tools. None of the markers evaluated over the last years showed remarkable sensitivity or specificity for the identification of any of the diverse types of bladder cancer in clinical practice. The limitations of the known prognostic markers have led to the research of new molecular markers for early detection of bladder cancer. This research focused in particular on the discovery of biomarkers capable of reducing the need for periodic cystoscopies or, ideally, offering a non-invasive examination instead. In this review, we will examine various new markers of bladder cancer and their value in the diagnosis and follow-up of non-muscleinvasive bladder cancer. When compared with urine cytology, which showed the highest specificity, most of these markers demonstrated an increased sensitivity.

RESUMO

The formulation of proper evaluation criteria after superficial bladder cancer therapy poses several methodological problems that are often peculiar to the disease. The Achilles' heel of many trials is possibly found in the criteria used for the evaluation of the trial outcomes. As a consequence of that, total agreement regarding the criteria for response and the evaluation of response is needed. The adoption of standard response criteria should be given high priority. Uniform response criteria should be chosen because they meet standards of reliability and statistical validity. Thus, the criteria must be reproducible, and they should correlate with some measures of patient's benefit, such as quantity and quality of survival. A proposal of standardization in superficial bladder cancer clinical trials is presented based upon current knowledge on the methodology for conducting clinical trials and upon the experience coming from major clinical research groups.

RESUMO

PURPOSE. Congenital abnormalities and acquired disorders can lead to organ damage and loss. Nowadays, transplantation represents the only effective treatment option. However, there is a marked decrease in the number of organ donors, which is even yearly worsening due to the population aging. The regenerative medicine represents a realistic option that allows to restore and maintain the normal functions of tissues and organs. This article reviews the principles of regenerative medicine and the recent advances with regard to its application to the genitourinary tract. RECENT FINDINGS. The field of regenerative medicine involves different areas of technology, such as tissue engineering, stem cells and cloning. Tissue engineering involves the field of cell transplantation, materials science and engineering in order to create functional replacement tissues. Stem cells and cloning permit the extraction of pluripotent, embryonic stem cells offering a potentially limitless source of cells for tissue engineering applications. Most current strategies for tissue engineering depend upon a sample of autologous cells from the patient's diseased organ. Biopsies from patients with extensive end-stage organ failure, however, may not yield enough normal cells. In these situations, stem cells are envisaged as being an alternative source. Stem cells can be derived from discarded human embryos (human embryonic stem cells), from fetal tissue or from adult sources (bone marrow, fat, skin). Therapeutic cloning offers a potentially limitless source of cells for tissue engineering applications. Regenerative medicine and tissue engineering scientists have increasingly applied the principles of cell transplantation, materials science and bioengineering to construct biological substitutes that will restore and maintain normal function in urological diseased and injured tissues such as kidney, ureter, bladder, urethra and penis. CONCLUSIONS. Regenerative medicine offers several applications in acquired and congenital genito-urinary diseases. Tissue engineering, stem cells and, mostly, cloning have been applied in experimental studies with excellent results. Few preliminary human applications have been developed with promising results.

RESUMO

Peyronie's disease (PD) is characterized by the onset of a fibrous plaque within the tunica albuginea of the penile corpora cavernosa, resulting in pain and bending during the erection, which can make the intercourse difficult or impossible. Evidence from literature supports the autoimmune etiology of PD, and suggests genetic and familiar conditions, penile traumatisms and history of genital tract diseases as risk factors, even though no definitive conclusions arise about the pathogenesis of the disease. Few randomized trials demonstrated that medical therapies, such as Vitamin E, Colchicine, Potassium amminobenzoate, Tamoxifen and injection therapy with Verapamil are effective in stabilizing the acute phase of the disease. Extracorporeal shock wave therapy (ESWT) and ionophoresis cannot be considered as first line or gold standard therapies. Satisfactory results have been published about Nesbit operation in large number of cases with low-stage disease, whereas plication procedures have shown significant rates of relapse. High incidence of long-term penile retraction have been reported in high-stage disease treated with plaque incision and simple graft insertion. Malleable, soft or inflatable prostheses combined with graft implant have given the best results in terms of penile straightening and lengthening and patients' satisfaction. In conclusion, the PD etiopathogenesis hasn't been clearly understood-yet, no medical therapy is fully effective; surgery remains therefore the gold standard in case of severe deformity and/or erectile dysfunction.
