RESUMO
Damage to gut mucosa following conditioning regimens may favour bacterial infections that can trigger graft versus host disease (GvHD) in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Rifaximin, an oral and non-absorbable antibiotic, has been recently proposed as effective prophylaxis to reduce bacterial infections in the gut and consequently acute GvHD in this setting. The present study evaluated safety and outcomes of HSCT patients that were treated with rifaximin prophylaxis at Perugia University Hospital. Rifaximin prophylaxis was introduced as standard of care in HSCT patients in May 2018. We retrieved data from 118 consecutive transplants, and we compared the outcomes of rifaximin-treated patients with historical controls that did not receive antibiotic prophylaxis. While incidences of neutropenic fever, documented bacterial infections, and aGvHD were similar in the two groups, we found an increased frequency of invasive candidiasis and clinically relevant Candida spp. infections in rifaximin-treated patients (5 patients vs 1 patient, 25% [± 0.99%] vs 1% [± 0.01%], p < .0001). Three rifaximin-treated patients experienced life-threating candidemia (2 C. krusei, 1 C. orthopsilosis). Rifaximin was the only factor that increased the risk of Candida spp. infections. Rifaximin could have contributed to microbiome disruption which favoured an outbreak of life-threatening Candida infections. This important complication forced us to halt its use. Larger, prospective studies are needed to assess the impact of rifaximin prophylaxis on incidence of bacterial infections, aGvHD, and survival of HSCT patients.

OBJECTIVES: The Italian Society of Andrology, i.e. "Società Italiana di Andrologia" (S.I.A.), launched on December 2014 a prospective, multicenter, monitored and internal review board approved Registry for penile implants, the "INSIST-ED" (Italian Nationwide Systematic Inventarisation of Surgical Treatment for ED) Registry. Purpose of this first report is to present a baseline data analysis of the characteristics of penile implant surgery in Italy. MATERIAL AND METHODS: The INSIST-ED Registry is open to all surgeons implanting penile prostheses (all brands, all models) in Italy, providing anonymous patient, device, surgical procedure, outcome, follow-up data, for both first and revision surgeries. A Registry project Board overviews all the steps of the project, and a Registry Monitor interacts with the Registry implanting surgeons. RESULTS: As by April 8, 2016, 31 implanting surgeons actively joined the Registry, entering 367 surgical procedures in its database, that comprise: 310 first implants, 43 prosthesis substitutions, 14 device explants without substitution. Implanted devices account for: 288 three-component devices (81,3%), 20 two-component devices (5,4%), 45 non-hydraulic devices (12,3%). Leading primary ED etiologies in first implant surgeries resulted: former radical pelvic surgery in 111 cases (35,8%), Peyronie's disease in 66 cases (21,3%), diabetes in 39 cases (12,6%). Two intraoperative complications have been recorded. Main reasons for 57 revision surgeries were: device failure (52,6%), erosion (19,3%), infection (12,3%), patient dissatisfaction (10,5%). Surgical settings for patients undergoing a first penile implant were: public hospitals in 251 cases (81%), private environments in 59 cases (19%). CONCLUSIONS: The INSIST-ED Registry represents the first European experience of penile prosthesis Registry. This baseline data analysis shows that: three-pieces inflatable prosthesis is the most implanted device, leading etiology of erectile dysfunction (ED) in patient receiving a prosthesis is former radical pelvic surgery, primary reason for revision surgery is device failure, primary settings for first penile implant surgery are public hospitals. Evaluation of penile implant impact on recipients quality of life is presently ongoing.

INTRODUCTION: The phosphodiesterase type 5 (PDE5) inhibitors are generally well tolerated and effective for treating erectile dysfunction (ED), including in patients with significant comorbidity. Because of this benign safety profile, investigators have used PDE5 inhibitors to treat patients with ED and severe renal disease or those who have received renal transplants. AIM: To assess safety and efficacy of PDE5 inhibitors in patients receiving dialysis or renal transplants. MAIN OUTCOME MEASURES: Erectile function as assessed by the International Index of Erectile Function (IIEF) and Global Assessment Questions; adverse events (AEs). METHODS: We reviewed published studies of PDE5 inhibitors in patients receiving dialysis or renal transplants. RESULTS: In double-blind, placebo-controlled studies in patients receiving dialysis or renal transplants, sildenafil significantly improved erectile function as assessed by the IIEF, and 75-85% of patients reported improved erectile function on Global Assessment Questions; efficacy was more variable in less well-controlled studies. In >260 patients undergoing dialysis who received sildenafil in clinical studies, there were only six reported discontinuations because of AEs (headache [N=3], headache and nausea [N=1], gastrointestinal [N=1], and symptomatic blood pressure decrease [N=1]). In approximately 400 patients with renal transplants who received sildenafil, only three patients discontinued because of AEs. Vardenafil improved IIEF scores of up to 82% of renal transplant recipients in randomized, controlled studies (N=59, total), with no reported discontinuations because of AEs. Limited data also suggest benefit with tadalafil. CONCLUSIONS: ED is common in patients undergoing renal dialysis or postrenal transplant and substantially affects patient quality of life. Sildenafil and vardenafil appear to be efficacious and well tolerated in patients receiving renal dialysis or transplant.

Hypoglycemia in patients without diabetes is a diagnostic challenge for the endocrinologist. Sometimes it is related to rare causes such as Doege-Potter Syndrome (DPS). DPS is caused by an abnormal insulin-like grow factor 2(IGF-2) that retains part of the E domain during the production process, resulting in a longer peptide called "big-IGF-2". We present a case report of DPS with emphasis on the diagnosis and especially on the difficulties in interpreting the biochemical findings. An elderly patient with an intrathoracic neoplasm and hypoglycemia underwent various tests: insulin autoantibodies and fasting test were both negative. She had low values of IGF-1 and normal values of IGF-2 that apparently excludes a diagnosis of DPS. The evaluation of the IGF-2/IGF-1 ratio is the most important test because a ratio >10 is widely considered to be indicative of non-islet cell tumor hypoglycemia (NICTH). Glucose infusion and steroid therapy were used to control the hypoglycemia, but the definitive treatment was surgery, which almost immediately reversed the hypoglycemia. The differential diagnosis of hypoglycemia should include rare causes such as DPS, and the IGF-2/IGF-1 ratio is a useful tool.
RESUMO
Like all surgeries, penile prosthesis implantation (PPI) has the potential for both postoperative complications and suboptimal patient satisfaction. In order to assess risk factors for poor satisfaction, we reviewed patients who had been prospectively recruited in a national multi-institutional registry of penile prostheses procedures (INSIST-ED) from 2014 to 20121. Patient baseline characteristics and postoperative complications were recorded. The primary endpoint of this study was unfavorable outcomes after inflatable PPI, defined as significant postoperative complications (Clavien-Dindo ≥2) and/or Sexuality with Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) scores below the 10th percentile. A total of 256 patients were included in the study. The median age was 60 years (IQR 56-67). The most common cause of erectile dysfunction (ED) was organic (42.2%), followed by pelvic surgery/radiotherapy (39.8%) and Peyronie's disease (18.0%). Postoperative complications were recorded in 9.6%. High-grade complications (Clavien ≥2) occurred in 4.7%. At 1-year follow-up, the median QoLSPP total score was 71 (IQR 65-76). In all, 14.8% of patients were classified as having experienced unfavorable outcomes because of significant postoperative complications and/or QoLSPP scores below the 10th percentile. Logistic regression analysis demonstrated patient age to be non-linearly associated with the risk of experiencing unfavorable outcomes. A U-shaped correlation showed a lower risk for younger and older patients and a higher risk for middle-aged men. ED etiology and surgical volume were not associated with PPI outcomes. Physicians should, therefore, be aware that middle-aged men may be at higher risk of being unsatisfied following PPI compared to both younger and older patients.
RESUMO
BACKGROUND: Penile prosthesis implantation has been associated with overall good functional outcomes. Of relevance, some patients reported higher level of satisfaction and quality of life. AIM: We investigated the profile of the patients who may benefit the most from penile prosthesis implantation. MATERIALS AND METHODS: Data from a national multi-institutional registry of penile prostheses including patients treated from 2014 to 2017 in Italy (Italian Nationwide Systematic Inventarization of Surgical Treatment for Erectile Dysfunction) were analyzed. All data have been prospectively recorded by 45 surgeons on a dedicated website (www.registro.andrologiaitaliana.it) and revised by a single data manager. Patients' baseline characteristics were recorded. In order to simultaneously evaluate perceived penile prosthesis function and quality of life, all patients were re-assessed at 1-year follow-up using the validated questionnaire Quality of Life and Sexuality with Penile Prosthesis. High quality of life after surgery was defined as a score higher than the 75th percentile in each of the subdomains of the Quality of Life and Sexuality with Penile Prosthesis questionnaire. Logistic regression analysis tested the association between clinical characteristics and high quality of life after penile prosthesis implantation. RESULTS: Follow-up data were available for 285 patients (median age 60 years; interquartile range: 56-67) who underwent penile prosthesis implantation. Erectile dysfunction etiology was organic in 40% (114), pelvic surgery/radiotherapy in 39% (111), and Peyronie's disease in 21% (60) of the cases. Patients showed good overall Quality of Life and Sexuality with Penile Prosthesis scores at 1-year follow-up for functional (22/25), personal (13/15), relational (17/20), and social (13/15) domains. Overall, 27.0% (77) of patients achieved scores consistent with the high quality of life definition. These patients did not differ in terms of median age (60 vs. 62), type of prosthesis (inflatable penile prostheses: 95% in both of the cases), and post-operative complications (10% vs. 14%) than those with lower quality of life score (all p > 0.1). At logistic regression analysis, erectile dysfunction etiology was the only factor independently associated with high quality of life at 1 year after surgery (p = 0.02). Patients treated for Peyronie's disease (odds ratio: 2.62; p = 0.01; 95% confidence interval: 1.20-5.74) were more likely to report better outcomes after accounting for age, post-operative complications, and surgical volume. CONCLUSION: Penile prosthesis implantation is associated with an overall good quality of life. The subset of patients affected by erectile dysfunction secondary to Peyronie's disease seemed to benefit the most from penile prosthesis implantation in terms of functional outcomes, relationship with their partners and the outside world, and perceived self-image. The systematic use of validated questionnaires specifically addressed at evaluating quality of life and satisfaction after penile prosthesis implantation should be further implemented in future studies to better define the predictors of optimal satisfaction after penile prosthesis implantation.

AIMS: This study aimed to investigate the relationship between cardio-ankle vascular index (CAVI) and diabetic retinopathy (DR) in Caucasian patients with type 2 Diabetes Mellitus (T2DM). METHODS: This was a cross-sectional study of 299 T2DM patients admitted to Endocrine Unit of Foggia. DR was diagnosed using the International Clinical Disease Severity Scale of American Academy of Ophthalmology. The VaSera VS-1500N was used to measure CAVI. Because age is the most powerful determinant of arterial stiffness and affects the progression of DR, we divided the whole sample into two subgroups: above (older) and below (younger) 70â¯years. RESULTS: The mean age of patients was 60.4⯱â¯12.6â¯years and the mean CAVI value was 8.6⯱â¯1.7. In the whole population DR was diagnosed in 74 (24.7%) patients. CAVI value was clearly higher in patients with DR (9.5⯱â¯1.6) than in those without (8.7⯱â¯1.7) (Pâ¯=â¯0.001) although this difference was not any more significant when adjusted by age and gender (Pâ¯=â¯0.067). In the multivariate model taking into account several possible confounders, the correlation between DR and CAVI remained significant only in younger subjects. In the same subgroup we found a significant association between the stages of DR and CAVI (pâ¯=â¯0.019 adjusted by age and gender). CONCLUSIONS: This study shows that CAVI is significantly higher in younger patients with DR than in those without, with a relationship between the stages of DR and CAVI in the same subgroup. Physicians should pay attention to sub-clinical macroangiopathy in younger T2DM patients who have DR.

Implantation of an inflatable penile prosthesis (IPP) is a well-established definitive solution for erectile dysfunction when conservative treatments fail. Penile implants may shorten the penis. The AMS 700 LGX IPP is in common use but reports on its mechanical reliability, medium-term postsurgical patient satisfaction, and mean penile length preservation are lacking. We investigate the mean penile length, mechanical reliability, and patient satisfaction at 6 and 12 months after implantation of the AMS 700 LGX. This prospective study consecutively enrolled men undergoing first-time IPP implant surgery from February 2009 to April 2012. Stretched flaccid penile length, penile length at 50% and 100% of stiffness (P50 and P100) and International Index of Erectile Function (IIEF) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, were measured at 6 and 12 months postsurgery. Of 45 patients who underwent AMS 700 LGX implantation (median age 61 years) and completed 6 months' follow-up, 36 (80%) completed the study. A significant difference in stretched flaccid penile length was seen between 6 and 12 months (P = 0.033). P100 was also significantly increased at 6 and 12 months, with a mean 10% increase (1.3 ± 0.4 cm) from baseline to 12 months. Differences in mean IIEF scores at 6 and 12 months were significant for the desired domain (P = 0.0001) and for overall satisfaction (P = 0.002); however, mean EDITS scores at 6 and 12 months were not significantly improved. AMS 700 LGX is a powerful tool for preserving penile length in men undergoing penile prosthesis implantation.

Surgical treatment of Induratio Penis Plastica includes conservative procedures (phalloplasty), substitutive procedures (prosthesis) and combined procedures (phalloplasty plus prosthesis). Our policy for conservative treatment is based on radical removal of the plaque and replacement with biological patches. During a 15 year experience we employed lyophilized dura mater, autologous dermal graft, preputial skin, cadaveric dermal graft (AlloDerm), venous graft and porcine SIS (Small Intestine Submucosa) graft. Our experience confirms the superiority of venous grafts, but preliminary results with SIS grafts are encouraging.
