RESUMEN

A hip fracture is a serious injury with life-threatening complications, and its risk rises with increasing age. A hip fracture can be a very painful condition, and prompt surgical treatment is recommended to reduce pain and complications. Pain management is considered integral to the management of a broken hip. The choice between general and regional anesthesia in hip fracture surgery continues to be a topic of debate because risks are potentially associated with both approaches. Nerve blockades have proven to be effective in reducing acute pain after a hip fracture and in the perioperative period. For this reason, many regional techniques have been introduced, such as the lumbar plexus block, fascia iliac block, femoral nerve block, and recently, the pericapsular nerve group (PENG) block. Hip joint innervation is complex, not limited to the lumbar plexus but also depending on the sciatic nerve and branches of the sacral plexus (superior and inferior gluteal nerves and an articular branch from the quadratus femoris nerve). We hypothesized that a combination of two emerging regional anesthesia techniques, such as the PENG block and sacral erector spinae plane (S-ESP) block, could represent a good option to obtain pain control of the whole hip joint without opioid administration intraoperatively and postoperatively. Here, we report the cases of three frail patients with significant comorbidities who underwent hip fracture surgery (two cases of intramedullary nailing and one hemiarthroplasty), in which we preoperatively performed PENG and S-ESP blocks. We registered optimal intraoperative and postoperative pain control up to 48 hours after surgery without complications and without opioid administration, allowing the surgery to be performed with intravenous sedation or laryngeal mask general anesthesia. The surgeries were uneventful, and no complications were reported. This approach warrants further investigation in hip fracture surgery.

RESUMEN

The aim of this paper is to describe our surgical technique and results of proper 6-branch autologous sling tensioning during RALP employing intraoperatively the Retrograde Perfusion Sphincterometry (RPS). Between May 2016 and February 2020, 374 patients underwent RALP with the 6-branch suburethral autologous sling tensioned under intraoperative guidance of RPS. Surgical procedure: Retrograde Leak Point pressure (RLPP) was evaluated by means of RPS after pneumoperitoneum induction (RLPPp), after urethrovescical anastomosis (RLPPa) and during proper sling tensioning (RLPPs). The goal of the sling tensioning was to obtain at the end of the procedure similar pressures as after pneumoperitoneum induction (RLPPs ≅ RLPPp). Intraoperative variables, postoperative complications, and continence recovery outcomes were assessed. A descriptive statistical analysis was performed. Sling positioning and tensioning was feasible in all patients. Mean operative time was 215 min. Proper sling tensioning allowed for the possibility to restore sphincteric efficacy to preoperative value (RLPPs vs. RLPPp (42.5 vs. 42.6) cmH2O). Urinary continence was achieved, respectively, in 58%, 67%, 74%, 88% and 92% of patients after 24 h, 10 days, 1 month, 6 months and 1 year after catheter removal. In conclusion, RPS revealed a valid option for proper autologous 6-branch sling tensioning during RALP, offering the possibility to restore sphincteric apparatus efficiency to its preoperative status to improve EUC.

RESUMEN

INTRODUCTION:: Circumcision is a common surgical procedure, typically performed under local anesthesia and somehow also as outpatient clinic. Although complications are rare and most frequently related to the procedure itself, ischemia of the glans may occur as a major complication and can be related to local ischemia following dorsal penile nerve block. CASE DESCRIPTION:: We describe the case of a 33-year-old patient who underwent circumcision at our institution and, 24 h after the procedure, developed an acute ischemia of the glans; a re-intervention was performed in emergency setting to ensure a large, not-tightened circular suture under the glans, and low-molecular-weight heparin and antiplatelet therapy was introduced to achieve anti-coagulative/antiaggregant effects. After 48 h, the skin returned to its normal color and in 7 days the penile glans achieved complete remission of the ischemic aspect. A 6-month follow-up confirmed regular outcomes with normal erectile functions. CONCLUSION:: The treatment we proposed to treat acute post-circumcision ischemia of the glans is a simple and effective one, with a perfect aesthetic and functional outcome observed within 4 weeks and confirmed at 6-month follow-up.

RESUMEN

OBJECTIVE: The aim of this study is to describe (urodynamically) the effect of the use of a 6-branch autologous suburethral sling, made with absorbable sutures and vas deferens, to support the bladder neck and urethra during robot-assisted laparoscopic prostatectomy (RALP) to improve early urinary continence (EUC) recovery. MATERIALS AND METHODS: Retrograde leak point pressure (RLPP) was intraoperatively evaluated, by means of retrograde perfusion sphincterometry (RPS), in 77 patients (mean age ± standard deviation [SD]: 65.64 ± 7.23 years, mean body mass index ± SD: 26.69 ± 3.89) scheduled to undergo RALP at our institution. RLPP was evaluated before (RLPPb) and after pneumoperitoneum induction (RLPPp). RLPP was then evaluated after urethrovesical anastomosis (RLPPa) and after proper sling tensioning (RLPPs), with the aim to obtain the same pressure as after pneumoperitoneum induction. EUC recovery, defined as the use of no pad, was assessed 10 days, 30 days, and 6 months after catheter removal. RESULTS: RPS and proper autologous 6-branch sling positioning were feasible in all patients, without perioperative complications and negligible impact on overall operative time. Pneumoperitoneum induction increased, similarly, RLPP in all patients. An important decrease of sphincteric capability was evident after prostate removal and the following urethrovesical anastomosis, while proper sling tensioning allowed for restoration of sphincteric apparatus capability to its presurgical status (mean RLPPs 40.84 cmH2O vs RLPPp 40.39 cmH2O, p = 0.942). EUC recovery within 10 days after catheter removal was achieved in 59 (77%) patients and progressively improved over time. CONCLUSIONS: RPS, intraoperatively performed during RALP, allows for precise evaluation of the impact of the surgical procedure on sphincteric apparatus competence. Moreover, the use of the 6-branch suburethral sling, in association with RPS, allows for restoration of the proper supporting system to the urethral sphincter, similar to the preoperative condition, offering the basis for EUC recovery after radical prostate surgery.

RESUMEN

We have recently described the use of a retropubic suburethral autologous sling created and placed during robotic radical prostatectomy (RARP). In this study, we assess the effectiveness of newly designed six-branches compared to two-branches suburethral autologous sling in improving early urinary continence (UC) recovery. 120 patients submitted to RARP were prospectively randomized according to the intraoperative positioning of six-branches (group 1, n = 60) or two-branches autologous sling (group 2, n = 60) obtained by different configuration of a same tract of vas deferens removed. Early UC recovery was assessed at 5 (catheter removal), 10 and 30 days postoperatively through the daily number of pads used and the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) score. UC was defined as the non-use of pad. Chi square test and Wilcoxon test were used to investigate UC recovery between the two groups. Moreover, post-voiding residual was evaluated in each patient at the same time. At catheter removal, UC rate was in groups 1 and 2, 60 and 35% (p = 0.02); at 10 days 70 and 46% (p = 0.03); at 30 days 87 and 70% (p = 0.04), respectively. One patient in group 1 experienced acute urinary retention at the time of catheter removal and was treated uneventfully with a further 7-day catheterization. These preliminary data indicate that newly designed six-branches suburethral autologous sling is able to increase the rate of early UC recovery compared to the two-arms sling previously described by us.

RESUMEN

The standard low lithotomic position, used during robot-assisted radical prostatectomy (RARP), with prolonged positioning in stirrups together with steep Trendelenburg may expose the patient to neurapraxia phenomena of the lower limbs and can rarely be used in patients with problems of hip abduction. To overcome these hurdles, we evaluated the clinical benefits of "side docking" (SD) of the da Vinci(®) robotic system in comparison to "traditional docking" (TD). A cohort of 120 patients submitted to RARP were prospectively randomized into two groups by docking approach: SD with the patient supine with lower limbs slightly abducted on the operating table, and TD docking time, intraoperative number of collisions between the robotic arms and postoperative neurological problems in the lower limbs were noted. Descriptive statistics was used to analyze outcomes. Docking time was shorter for the SD group [SD: median 13 min (range 10-18); TD: median 21 min (range 15-34)]. None in the SD group and six of 60 patients (10%) in the TD group suffered from temporary (<30 days) unilateral neurological deficits of the lower limbs. In both groups no collisions between the robotic arms occurred. The SD approach is technically feasible. It does not cause collisions between the robotic arms, and is a reliable method for reducing the setup time of RARP. The supine position of the patient may prevent neurological complications of the lower limbs. Based on these results, SD has become the standard docking technique used by our department.

RESUMEN

We report a case of a 75-year-old male with biopsy-proven prostate cancer and candidate for radical prostatectomy. The patient's medical history includes hypertension and atrial fibrillation in prophylactic treatment; however, he was suffering from recurrent paroxysmal episodes of supraventricular tachycardia. Abdominal magnetic resonance performed for prostate cancer staging detected a non-lymphatic inter-cavo-aortic mass of 42 × 37 × 43 cm. Results of biochemical screening confirmed the clinical diagnosis of symptomatic paraganglioma. The patient was subjected in a single robotic session for concurrent excision of the inter-aortocaval mass and radical prostatectomy with bilateral pelvic lymph-node dissection. During the procedure, there were no anesthesiological or surgical complications. The postoperative course was uneventful and the patient was discharged on postoperative day 5. Six months after surgery, his prostate-specific antigen level was undetectable and the abdominal magnetic resonance imaging was negative for local recurrence or metastasis of paraganglioma. No more episodes of tachycardia were reported or antihypertensive therapy was necessary.

RESUMEN

BACKGROUND AND PURPOSE: Urinary continence (UC) recovery remains bothersome for patients even after robot-assisted radical prostatectomy (RARP). We describe the first retropubic suburethral autologous sling created and placed during RARP. The surgical technique and preliminary data regarding its effectiveness in improving early UC recovery are presented. PATIENTS AND METHODS: Between November 2013 and February 2014, 60 patients who underwent RARP at a single high-volume center were prospectively randomized into sling and nonsling groups. Early UC was assessed at 5 days (time of catheter removal), 10 days, and 30 days postoperatively by the daily number of pads used and the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) score. Sling-related operative time and urethral erosion were also analyzed. Chi-square and independent sample t tests were used to investigate surgical and functional outcomes between groups. RESULTS: Complete data were available for all patients. Mean ± standard deviation (SD) numbers of pads used daily in nonsling and sling groups, respectively, were 1.9 ± 1.2 versus 1.7 ± 1.4 (P = 0.5) at 5 days, 1.8 ± 1.3 versus 1.3 ± 1.3 (P = 0.1) at 10 days, and 1.1 ± 1.2 versus 0.4 ± 0.8 (P = 0.01) at 30 days. At 1 month, mean ± SD ICIQ-UI-SF scores in nonsling and sling groups, respectively, were 4.8 ± 4.6 versus 1.8 ± 3.4 (P = 0.01); sling patients were associated with pad-free status (76% vs 46%, P = 0.03). The advantage in UC recovery was also observed in sling patients at 3, 6, and 12 months postoperatively. Surgical time did not differ between groups, and in sling patients, no cases of urethral erosion or uroflowmetry suggestive of urinary obstruction were found. Limitations included the small sample size and the lack of assessment of morphologic and urodynamic changes produced by the sling. CONCLUSIONS: The suburethral autologous sling is technically feasible and may improve early UC recovery after RARP. These preliminary results should be confirmed in a larger sample of patients.

RESUMEN

Obesity is a major health issue in modern society, and with the progressive widespread employment of robotic assisted radical prostatectomy (RALP), the urologist-robotic surgeon is increasingly involved in the treatment of obese patients. However, the vast majority of urological departments are not equipped with a complete set of bariatric instruments. One of the potential difficulties of robotic surgery on the morbidly obese patient is the relatively short length of the optical trocar sheath, as the optical robotic arm requires some very valuable centimeters of the sheath to hang onto. This condition may make it impossible to properly reach the peritoneal cavity with the optical trocar during the RALP procedure. We present a series of four morbidly obese patients (BMI ranging from 42.1 to 46.2) with localized prostate cancer treated with RALP. We have developed an effective and "easy-to-implement" solution to the problem of properly elongating the sheath of the optical trocar which involves the use of the plastic cylindrical transparent protective tube of a disposable 26-Ch Amplatz sheath. The Amplatz sheath, with an internal diameter of 13 mm and length of 25 cm, perfectly fits outside of the 13-mm trocar usually employed for the optical trocar. Additionally, the cylindrical tube perfectly fits and hangs onto the robotic optical arm system. Mean operative time was 202.5 min (range 185-220 min). Mean blood loss was 284 mL (range 185-380 mL). Catheterization time and hospital stay were 5 and 6 days, respectively, in all patients. All procedures were safely completed, and no minor or major complications were reported. The optical trocar lengthening technique allowed us to properly perform RALP procedures even in severely morbidly obese patients in an urological setting not equipped for bariatric minimally invasive surgery.

RESUMEN

BACKGROUND: The surgical management of ureteropelvic junction obstruction (UPJO) has dramatically evolved over the past 20 yr due to the development of new technology. OBJECTIVE: Our aim was to report the feasibility and efficacy of robot-assisted pyeloplasty (RAP) performed by either the retroperitoneal or the transperitoneal approach. DESIGN, SETTING, AND PARTICIPANTS: A stage 2 investigative study was conducted including development (stage 2a) and exploration (stage 2b) of transperitoneal and retroperitoneal RAP performed in 55 patients at an urban tertiary university department of urology. SURGICAL PROCEDURE: Retroperitoneal RAP was performed with the patient in full flank position using a 12-mm Hasson-style optical port at the tip of the 12th rib, plus two operative 8-mm robotic trocars and an assistant 5-mm port. The stenotic ureteropelvic junction was excised, the ureter was spatulated, and a dismembered pyeloplasty was performed in all cases. Transperitoneal RAP was performed with the patients in the 60° flank position. The optical port is in the umbilical area, plus two 8-mm operative robotic ports and one 5-mm assistant port. The pyeloplasty technique is similar to the retroperitoneoscopic approach. In both groups, the stent can be positioned in an anterograde or retrograde fashion. MEASUREMENTS: Success consisted of no evidence of obstruction on computed tomography urography or mercaptoacetyltriglycine-3 diuretic renal scan, no postoperative symptoms, and no further treatment. RESULTS AND LIMITATIONS: Thirty-six patients underwent retroperitoneoscopic RAP and 19 transperitoneal RAP for UPJO. All the procedures were completed with robotic assistance. The overall objective success (measured by diuretic renal scan and/or imaging techniques) was 96% with two cases of recurrence (both in the retroperitoneal group). The main limitation was the short follow-up, although all patients reached at least a 6-mo follow-up. CONCLUSIONS: RAP performed either retroperitoneally or transperitoneally was revealed as a feasible and reproducible surgical option for the treatment of UPJO, offering a subjective optimal plasty reconfiguration at short follow-up.

RESUMEN

BACKGROUND: The oral mucosa (OM) is a popular substitute for urethroplasty. OBJECTIVE: The aim of this study was to investigate oral morbidity and patient satisfaction in a homogeneous group of patients who underwent OM harvesting. DESIGN, SETTING, AND PARTICIPANTS: This study is a prospective analysis of 350 patients who underwent OM harvesting from a single cheek. INTERVENTION: The graft was harvested in an ovoid shape with closure of the wound. Standard graft size was 4 cm in length and 2.5 cm in width. MEASUREMENTS: Self-administered, nonvalidated semiquantitative (0, absence of complications or symptoms; 3, the worst complication or symptom) questionnaire consisting of six questions was used to investigate early complications, with 13 questions designed to investigate late complications and patient satisfaction. RESULTS AND LIMITATIONS: Early complications included bleeding, which occurred in 15 patients (4.3%); two patients required immediate surgical revision of the harvesting site. The majority of patients (85.2%) showed no pain, and only 3.7% of patients required use of anti-inflammatory drugs. The majority of patients (65.8%) showed slight or moderate swelling. With respect to late complications, most of the patients (73.4%) reported oral numbness for 1 wk, 22.9% for 1 mo, and 3.77% for 3 mo. Numbness resulting from scarring was absent or slight in most of patients. Changes in oral sensitivity occurred in 2.3% of patients. No difficulties opening the mouth or smiling was found in 98.3% and 99.7% of patients, respectively. Slight or moderate dry mouth was found in 97.1% of patients. In response to the question, "Would you undergo oral mucosa graft harvesting using this technique again," 343 patients (98%) replied "yes," and 7 patients (2%) replied "no." CONCLUSIONS: The harvesting of an OM ovoid graft from a cheek with closure of the wound is a safe procedure with a high patient satisfaction rate.

RESUMEN

The modern urologists are nowadays greatly involved in the surgical management of small renal masses, where nephron sparing surgery showed adequate oncological results, with a saving of a great amount of healthy renal tissue. Among the various minimally invasive surgical options, laparoscopic partial nephrectomy duplicates the open technique considered the standard of referral. Robotic assisted partial nephrectomy, aims to add to laparoscopy all the well known advantages offered by the Da Vinci system, such as the 3-Dvision and 7 degree of freedom of surgical instruments. We reviewed the current English literature on robotic partial nephrectomy published in 2008-2009 with at least 20 cases, adding our experience of 26 cases. Although the retroperitoneoscopic approach showed to be feasible in selected cases, all the procedures reported were performed with a transperitoneal approach. Among the 106 robotic assisted partial nephrectomy procedures selected, the mean tumor diameter was 2.8 cm; the mean operative time was 148.7 min with a mean warm ischemia time of 23.8 min and the positive surgical margins rate was 1.8%, reflecting the learning curve of the procedure. Overall complications rate was 15%, although the majority were minor and conservatively treated. Although robotic partial nephrectomy is still in its infancy, it showed adequate overall results when compared to laparoscopic partial nephrectomy with similar results but with a reduced learning curve. Actually robotic partial nephrectomy should be considered a viable option for nephron sparing surgery both in experienced laparoscopy centers for larger lesions in robotic naive centers where it may become the standard option for the treatment of small renal masses.

RESUMEN

INTRODUCTION: There is currently neither a clinically useful, reliable and inexpensive assay to measure circulating levels of free testosterone (T) in the range observed in women, nor is there agreement on the serum free T threshold defining hypoandrogenism that is associated with female-impaired sexual function. AIM: Following the Clinical and Laboratory Standards Institute guidelines, we generated clinically applicable ranges for circulating androgens during specific phases of the menstrual cycle in a convenience sample of 120 reproductive-aged, regularly cycling healthy European Caucasian women with self-reported normal sexual function. METHODS: All participants were asked to complete a semistructured interview and fill out a set of validated questionnaires, including the Female Sexual Function Index, the Female Sexual Distress Scale, and the 21-item Beck's Inventory for Depression. Between 8 am and 10 am, a venous blood sample was drawn from each participant during the midfollicular (day 5 to 8), the ovulatory (day 13 to 15), and the midluteal phase (day 19 to 22) of the same menstrual cycle. MAIN OUTCOME MEASURES: Serum levels of total and free testosterone, Delta(4)-androstenedione, dehydroepiandrosterone sulphate and sex hormone-binding globulin during the midfollicular, ovulatory and midluteal phase of the same menstrual cycle. RESULTS: Total and free T levels showed significant fluctuations, peaking during the ovulatory phase. No significant variation during the menstrual cycle were observed for Delta(4)-androstenedione and dehydroepiandrosterone sulphate. Despite the careful selection of participants that yielded an homogeneous group of women without sexual disorders, we observed a wide range of distribution for each of the circulating androgens measured in this study. CONCLUSIONS: This report provides clinically applicable ranges for androgens throughout the menstrual cycle in reproductive-aged, regularly cycling, young healthy Caucasian European women with self-reported normal sexual function.

RESUMEN

OBJECTIVES: Controversial data on penile length after radical retropubic prostatectomy are available. We hypothesised that postoperative penile size correlates to erectile function following bilateral nerve-sparing radical retropubic prostatectomy (BNSRRP). METHODS: Thirty-three consecutive patients with a preoperative erectile function domain of the International Index of Erectile Function (IIEF-EF) score indicating full potency (> or = 26) were prospectively enrolled. All patients underwent BNSRRP performed by one high-volume surgeon. All patients were preoperatively evaluated by IIEF-EF, analysis of comorbidities, physical examination, and penile power colour Doppler ultrasound using intracavernosal injection of prostaglandin E(1) (PGE(1)) 20 microg plus audiovisual and manual genital stimulation. Penile length and circumference were measured in flaccidity and at maximum erection. Six months postoperative, patients were assessed with the same protocol plus general assessment questions investigating penile structure and function. Statistical analysis was performed with an independent sample t test. RESULTS: Mean patient age was 56.5 yr. We found no difference between the preoperative and the 6-mo postoperative mean IIEF-EF domain score (27.2 vs, 26.7, respectively; p = 0.35). No difference was found in penile colour Doppler evaluation between the preoperative and postoperative periods (all p values > or = 0.3). We found no differences in penile length and circumference between the preoperative and postoperative evaluation either in the flaccid or in the erect state. Mean flaccid penile length (cm; preop vs. postop): 13.2 vs. 13 (p = 0.6). Mean flaccid penile circumference (cm; preop vs. postop): 11.1 vs. 11 (p = 0.7). Mean erect penile length (cm; preop vs. postop): 16.8 vs. 16.5 (p = 0.08). Mean erect penile circumference (cm; preop vs. postop): 15.6 vs. 15.3 (p = 0.2). CONCLUSIONS: This is the first report on penile changes in flaccidity and at maximum erection after BNSRRP in patients treated by one high-volume surgeon. The postoperative preservation of erectile function positively correlated with the maintenance of penile length following surgery. We found no change in penile size after surgery.

RESUMEN

INTRODUCTION: A prospective study to evaluate the reliability of cystoscopy was performed with fluorescence (photodynamic diagnosis, PDD) compared with standard white light (WL) cystoscopy in patients with solitary carcinoma in situ (CIS), undergoing BCG treatment. MATERIALS AND METHODS: Between February 2004 and March 2006, 49 patients suffering from CIS were enrolled in the study. Patients age was 68.5 ± 13.5 years (mean ± SD) and all presented CIS alone at inclusion. All suspicious areas were biopsied either under white light or blue light. Urine cytology was peformed on each patient before endoscopy. RESULTS: Out of 49 patients enrolled, 15 (30.6%) presented with positive urinary cytology. Out of 18 patients positive to CIS at biopsy, 14 (77.7%) could be diagnosed exclusively by means of PDD cystoscopy and transurethral bladder resection and 4 (22.3%) during both standard and PDD cystoscopy. No additional CIS could be diagnosed by standard WL cystoscopy alone. The overall false positive rate for PDD accounted for 33.3% compared with 7.1% for WL cytoscopy. A statistical correlation was documented between the number of CIS findings and PDD (r = 0.6976, p = 0.0002) while WL cystoscopy (r = 0.1870, p = 0.3816) and urinary cytology (r = 0.4965, p = 0.0136) correlated only weakly with CIS. The overall side effects related to the drugs were negligible overall. CONCLUSIONS: These data show that PDD cystoscopy is more reliable than WL cytoscopy for the follow-up of CIS patients during BCG treatment. Long-term data and multicenter, prospective data are needed to assess the true impact on tumor recurrence and progression.

RESUMEN

INTRODUCTION: Historically chocolate has been reported to exert several effects on human sexuality, mainly acting as an effective aphrodisiac, increasing sexual desire, and improving sexual pleasure. AIM: The aim of our study was to assess whether there is an association between daily chocolate intake and sexual function in a convenience sample of Northern Italian women. METHODS: A convenience sample of 163 women (mean +/- SD age: 35.3 +/- 9.2 years; body mass index [BMI]: 22.5 +/- 3.5 kg/m2), recruited through advertising, completed an anonymous semistructured interview on recreational habits and questionnaires to assess sexual function (Female Sexual Function Index [FSFI]), sexual distress (Female Sexual Distress Scale), and depression (Beck Depression Inventory and Center for Epidemiological Survey Depression Scale). RESULTS: Complete data were available for 153/163 (93.8%) women. Participants who reported daily chocolate intake (Group 1: 120 women) were significantly younger than those (Group 2: 33 women) who did not report to eat chocolate (33.9 +/- 0.8 years vs. 40.4 +/- 1.6 years, respectively) (P = 0.0003), despite a similar BMI. Participants in Group 1 had significantly higher total (P = 0.002) and desire domain (P = 0.01) FSFI scores than participants in Group 2. No differences between the two groups were observed concerning sexual arousal and satisfaction, sexual distress and depression. Our data also confirm that aging has a high statistically significant impact on women's sexual function. CONCLUSIONS: It is alluring to hypothesize that chocolate can have either a psychological or a biological positive impact on women's sexuality. In our sample women reporting chocolate consumption have higher FSFI scores than women who do not eat chocolate. However, when data are adjusted for age FSFI scores are similar, regardless of chocolate consumption.

RESUMEN

OBJECTIVE: Prior the widespread use of PSA screening in asymptomatic men, prostate cancer was historically detected by a simple digital rectal examination. Although the gold standard for prostate cancer still remains prostate biopsy, current researches in the area of detection and diagnosis of prostate carcinoma are focusing on identification of better sampling protocols, biologic markers and imaging strategies in order to detect disease at an earlier stage. We reviewed all the recent literature on the detection of clinically meaningful prostate cancer. METHODS: A systematic review of the literature using Medline up to 2005 was performed. Electronic searches were limited to the English language using the keywords prostate cancer, diagnosis, transrectal ultrasound, prostate biopsy. Unpublished information known by the authors and that were considered of interest to the readers were also included. RESULTS: The prostate biopsy technique has extremely changed from the original Hodge's sextant biopsy protocol. Several authors have already reported high rates of false negative biopsy using sextant protocols. The optimal protocol should, nowadays, include six standard sextant biopsies with additional biopsies weighted more laterally (anterior horn) and medially to the apex. Repeat biopsies should also be based on an extended scheme and should include the transition zone especially in patient with at initial negative biopsy. To increase accuracy of prostatic biopsy and reduce unnecessary prostate biopsy, TRUS, power Doppler imaging (PDI), colour Doppler TRUS (CDUS), and 3-dimensional Doppler (3DD) can be successfully adopted, but their routine use is still controversial. Several types of local anaesthesia are now available and can be safely performed to reduce the pain of multi-sites biopsy protocol. CONCLUSION: Extended biopsy schemes should be performed not only at first biopsy but especially at repeated biopsy for premalignancy lesions. The widespread use of local anesthesia makes the procedure more comfortable.

RESUMEN

Circulating levels of the neuro-hypophysial nonapeptide oxytocin increase during sexual arousal and orgasm in both men and women. A few studies have evaluated the effect of the menstrual cycle on plasma oxytocin in normally cycling, sexually active, healthy fertile women using or not using contraceptive pills. In 20 ovulating women and 10 women taking an oral contraceptive (group 1 and group 2, respectively), sexual function, hormonal profile, and plasma oxytocin (OT) were evaluated throughout the menstrual cycle. In group 1, plasma OT was significantly lower during the luteal phase in comparison with both the follicular and ovulatory phases. Plasma oxytocin was significantly correlated with the lubrication domain of the Female Sexual Function Index (FSFI) during the luteal phase and showed a trend towards statistical significance during the follicular phase. In group 2, plasma OT did not show any significant fluctuation throughout the menstrual cycle, even though a significant correlation was evident with both the arousal and the lubrication domain of the FSFI during the assumption of the contraceptive pill. These findings suggest that plasma OT fluctuates throughout the menstrual cycle in normally cycling healthy fertile women with adequate sexual activity but not taking any oral contraceptive pill. Moreover, plasma OT levels significantly relates to the genital lubrication in both women taking and not taking oral contraceptive pill apparently confirming its role in peripheral activation of sexual function.

RESUMEN

We have explored the synthesis of iron oxide particles, tubes, and fibrils within the pores of nanoporous polycarbonate and alumina membranes. The membranes contain uniformly distributed cylindrical pores with monodispersed diameters (varying between 20 and 200 nm) and thicknesses of 6 and 60 microm, respectively. By hydrolysis and polymerization of iron salts, particles of different sizes and phases were formed in the pores, building iron oxide particle nanowires. Alternatively, by the sol-gel technique, using as reagents metalloorganic compounds, fibrils and tubes of different iron oxide phases were prepared. Structural and morphological investigations performed using scanning electron microscopy and transmission electron microscopy revealed ordered iron oxide particle wires, tubes, and fibrils formed inside the membrane nanopores. Magnetic characterization was accomplished with a vibrating sample magnetometer. Below the blocking temperature (T(B)), the magnetic behavior of the nanowires was governed by dipolar interaction between nearest-neighbor nanoparticles inside the pore, whereas the energy barrier, and therefore the T(B) value, was mainly governed by dipolar interaction between magnetic moments over larger (interpore) distances. As expected, crystalline iron oxide nanotubes exhibited magnetic perpendicular anisotropy due to their magnetocrystalline and shape anisotropy.

RESUMEN

OBJECTIVE: The aim of this study was to determine the prevalence of sexual dysfunctions in women with urinary incontinence and/or lower urinary tract symptoms as compared to a general female population. METHODS: We extensively evaluated 227 consecutive women (mean age 52; age range 19-66) complaining of urinary incontinence (UI) and/or lower urinary tract symptoms (LUTS) with a comprehensive history (including several validated questionnaires), a complete physical examination and a urodynamic multichannel evaluation. Two hundred and sixteen patients were eligible for sexual function investigation because 11 out of 227 (5%) were not interested in dealing with questions regarding their own sexuality and were thus excluded from the final evaluation results. A group of 102 age-matched women (mean age 54; age range 19-63) assessed for a yearly routine gynaecological evaluation and not complaining of urinary symptoms were enrolled as cross-sectional controls and investigated in accordance with the Female Sexual Function Index (FSFI). RESULTS: Sexual dysfunction was diagnosed in 99 out of 216 patients (46%). Of these, 34 (34%) reported hypoactive sexual desire, 23 (23%) reported sexual arousal disorder; 11 patients (11%) complained of orgasmic deficiency, and 44 (44%) suffered from sexual pain disorder (e.g., dyspareunia or non-coital genital pain). Women reporting low sexual desire commonly suffered from stress incontinence (47%). We found that 60% of the women with sexual arousal disorders and 61% of those with sexual pain disorders also complained of recurrent bacterial cystitis. Forty-six percent of those complaining of orgasmic phase difficulties also reported a troublesome urge incontinence. The FSFI values in both groups scored as follows (patients versus controls; median value; p value): desire: 2.0 vs. 3.2 (p<0.01); arousal: 2.8 vs. 3.6 (p=n.s.); lubrication: 3.2 vs. 4.4 (p=0.01); orgasm: 4.1 vs. 4.4 (p=n.s.); sexual satisfaction: 2.7 vs. 4.0 (p<0.01); sexual pain: 1.8 vs. 4.0 (p<0.001). CONCLUSIONS: Women reporting UI or LUTS also complained of sexual dysfunctions in a significantly higher number than a general, healthy female population not complaining of urinary symptoms. Investigation of female sexuality is suggested for these patients.
