INTRODUZIONE: Abbiamo pensato di effettuare uno studio che indagasse circa la presenza delle citochine nell’albuginea di soggetti affetti da malattia di La Peyronie. Le citochine, in quanto responsabili della comunicazione intercellulare, potrebbero essere coinvolte nella patogenesi della malattia. L’individuazione di una o più citochine responsabili potrebbe, infatti, risultare utile nel trattamento farmacologico grazie ai c.d. farmaci biologici, in grado di interferire con le citochine. MATERIALI E METODI: Per lo studio sono stati reclutati tra gennaio 2009 e dicembre 2010 presso l’Ambulatorio di Chirurgia Andrologica del Policlinico di Palermo 20 soggetti affetti da malattia di La Peyronie (fig. 1) e 8 soggetti affetti da recurvatum penis congenito, questi ultimi adoperati come controllo. Come criteri di inclusione allo studio abbiamo considerato i criteri di operabilità con corporoplastica secondo Nesbit. I prelievi bioptici ottenuti dalle losanghe escisse in corso di intervento chirurgico sono stati utilizzati per saggiare l’espressione genica, attraverso Real-Time PCR, di citochine pro-fibrotiche e pro-infiammatorie. Inoltre sono stati sottoposti dopo fissazione ad esame istologico con la colorazione ematossilina-eosina. RISULTATI E DISCUSSIONE: L’esame istologico ha rilevato l’assenza di cellule infiammatorie in tutti i pazienti recensiti per lo studio. L’analisi dell’espressione dei geni codificanti per IL-4 (Interleuchina-4), IL-6 (Interleuchina-6), IL-13 (Interleuchina-13), TGF-β1 (Trasforming Growth Factor - β1), IL-2 (Interleuchina-2), IL-10 (Interleuchina-10), TNF-α (Tumor Necrosis Factor- α) e IFN-γ (Interferone- γ) ha evidenziato in tutti i campioni un livello molto basso di trascritti e in alcuni casi indosabili (fig. 2). Inoltre i livelli dei trascritti delle citochine prese in esame sono risultati minori nei campioni provenienti dagli individui affetti da malattia di La Peyronie rispetto ai controlli. CONCLUSIONI: Alla luce dei risultati ottenuti, l’utilizzo di farmaci biologici (anticorpi) contro le citochine non sembra essere applicabile nella fase stabile della malattia di La Peyronie

The aim of the study is to evaluate the efficacy of Diallil-Tiosulphinate, Nuciepherine and Diosgenin in the treatment of erectile dysfunction. In our study were selected 120 men affected by erectile dysfunction. They were filled in a self-administered questionnaire International Index of Sexual Medicine. 74 of them reported a moderate erectile dysfunction and 46 reported a severe ED. All patients were treated with Tadalafil 5 mg once a day for 90 days. They were re-evaluated with the same questionnaire after three months of therapy. In 75% of the patients there was an improvement of IIEF-5 score. Only the 90 patients responders to Tadalafil once a day were randomized and divided into two groups, each formed by 45 subjects. The group A was treated with the association of Diallil-Tiosulfinate, Nucipherine and Diosgenin on alternate days. The patients of group B were treated with placebo. After three months, there was a new evaluation with IIEF-5 score. In group A we reported a maintenance of improvement post-Tadalafil in 36 patients;in group B, only 18 patients have maintained the previous improvement, according to IIEF-5 score. The χ2 test is 13,38, with a p-value of about 0,00013.The maintenance’s odds ratio, confronting the two groups, is 6 with a confidence’s interval of 95%. The study shows that the utilization of the association therapy in patients with erectile dysfunction responders to Tadalafil once a day is able to duplicate the odds of maintenance’s improvement compared to placebo.

Introduction & Objectives: The aim of our study was to compare and analyse the effectiveness of pharmacological treatment and the psychotherapy alone or in association in terms of increase of Quality of Life (QoL) measured through Premature Ejaculation Diagnostic Tool (PEDT) and increase of intravaginal eiaculation latency time (IELT) in patients affected by primitive premature ejaculation(PE). Material & Methods: Between January and December 2012, in our department underwent to medical examination 540 patients complaining PE. Criteria for enrollment were primitive PE with IELT ≤ 2 minutes, PEDT > 9 and absence of psychiatric disease, severe chronic disease, drugs and alcool abuse. Out of 540 patients, 270 were elegible and were enrolled for the study. This patients were randomly divided in 3 group, A,B and C. Patients in Group A were treated with Dapoxetine, mean age 49,8 years(range 20-68). Patients in Group B were treated with Dapoxetine in association with Psycological counselling and group therapy, mean age 49,2 years. Patients in Group C were treated with psycologycal counselling and group therapy alone, mean age 36,9(range 20-56). In the Group A and B was precribed Dapoxetine 30 mg 1 cps 1h before the intercourse with increase in dose to 60mg in case of ineffectiveness. In group B and C after a first psycological counselling one by one patients entered in group therapy with 20 weekly scheduled meetings. All patients were followed for 20 weeks, with 4 schedueld visit during this period. The PEDT was administred before treatment and one month after the end of the therapy. Data were recorded and analysed trought a multivariated analysis. Results: Out of 270 patients enrolled, 120 (44,4%) were compliant to therapy and weren’t evaluable. GROUP A. Out of 90 patients enrolled 60 were compliant to the study. Mean IELT pre-treatment 79,75 sec (range 15 sec–120 sec) and mean PEDT score 15,95 (severe PE). Mean IELT post-treatment 203 sec and mean PEDT 8,26 (moderate PE). Thirteen patients(21,6%) showed an improvement of clinical with mean PEDT score ≤ 8 and IELT ≥ 2 ( p ≤ 0,001). GROUP B. Out of 90 patients enrolled 60 completed the scheduled therapy. Mean IELT pre-treatment 74,83 sec (range 15 sec–120 sec) and mean PEDT score 16 (sever PE). Mean IELT post-treatment 600 sec and mean PEDT 3,3 (absence PE/ light PE) (p ≤ 0,001). In all patients of Group B was detected a reduction of PE. GROUP C. Out of 90 patients enrolled only 30 patients completed the scheduled therapy. Mean IELT pre-treatment 75 sec (range 15 sec–120 sec) and mean PEDT score 15,7. Mean IELT post-treatment 323 sec and mean PEDT 4,03(absence PE/ light PE). Fifteen patients (50%)showed a reduction of PE.All the results analyzed by multivariate analysis were statically significative. Conclusions: Comparing the result obtained in our three groups: in the Group B (Pharmacotherapy plus Psycotherapy) all patients showed an improvement of IELT and PEDT, while in the group A (only Pharmacotherapy)and C (only Psycotherapy) the percentage of patients that reported an improvement of IELT and PEDT were respectively 21,6% and 50%. Our study demonstrate that the psyclogical counselling have a significative role in the treatment of PE. In particulary in association with the pharmacological therapy the psycological group therapy could increase the IELT and ameliorate QoL of patients affected by primitive PE as showed by the decrease of PEDT score.

Premature Ejaculation (PE) is a sexual dysfunction that concern 20-30% of the male population. Dapoxetine is a new serotonine re-uptake inhibitor (SSRI)specific for PE treatment.Aim of the study is to assess compliance and effectiveness of the treatment with dapoxetine compared to the treatment with citalopram (a classic SSRI used to treat PE).

INTRODUCTION & OBJECTIVES: Cytokines may be involved in the pathogenesis of the Peyronie's disease (PD). Cytokines levels in tunica albuginea (TA) specimens were measured by Real Time PCR in PD patients and in control group. MATERIAL & METHODS: Between January 2009 and December 2010 20 PD patients affected by PD and 8 patients affected by congenital recurvatum penis (control group) undergoing surgery were entered in the study. Routine histological examination and measurement by Real Time PCR of the expression of the encoding genes for IL-2, IL-4, IL-6, IL-10, IL-13, TGF-β1, TNF-α, IFN-γ and Metalloproteinase (MMP-2) were performed. For the normalization of data, GAPDH (glucerldehyde-3 fosfatehydrogenase) gene normally expressed in all cells was adopted. The analysis of the data was performed using the comparative method of Δct. The target gene expression were reported with the fold of induction (FOI) method calculated according to GAPDH both in PD and in control Group samples. RESULTS: The absence of inflammatory cells was demonstrated by routine histological examination in all samples. A lower median level of gene expression cytokines was detected in the PD patients when compared with the control group: IL-10 0,3864 (range 0- 1,1483), IL-2 0,089 (range 0- 0,3586), IL-6 0,0406 (range 0-0,1478), IFN-γ 0,029 (range 0-0,1187), MMP-2 0,2491 (range 0- 0,6480). IL-4, IL-13 and TNF-α were not detectable. No significant difference emerged between PD and control patients, although a trend for higher levels of TGF-β in PD patients 1,0396 (range 0,1540- 3,6432) vs 1 (control group). CONCLUSIONS: The expression of cytokines in tunica albuginea of PD patients compared to the control patients do not show any significative difference. Cytokines promoting inflammation are undetectable in PD patients and not seem to be involved in the pathogenesis of the disease. A higher level, althoug the difference was not statistically significative of the TGF- β, a profibrotic cytokine, was detected in PD patients representing a possible explain action of fibtotic tissue when the inflammation is off.

INTRODUCTION: The Nesbit procedure is the most common surgical technique to correct congenital or acquired penile curvature. It is a common opinion that this surgical procedure has to be completed with a circumcision to prevent foreskin necrosis or phimosis. According to our experience we believe that some procedural "tricks" could strongly reduce that mechanical and ischemic trauma on the foreskin responsible for these complications. MATERIALS AND METHODS: From 1988 to 2010 we selected 158 patients treated with Nesbit's corporoplasty. The procedure was recommended to patients who presented a penile curvature wider than 30° and reporting however some difficulty or pain at coitus, or to patients who complained about aesthetical problems (123 patients presented a La Peyronie disease and 35 presented a congenital curvature). RESULTS: Eleven patients underwent circumcision during surgery because of a pre-operative phimosis, or according to their own desire. Among the patients who did not undergo circumcision (147), paraphimosis was present in 3 patients. We reported only one case of curvature recurrence in a patient who had a sexual intercourse the day after surgery. We also had one case of hourglass effect in a congenital curvature. DISCUSSION: We believe that some tricks during Nesbit surgical procedure could prevent tissue and vascular trauma that give rise to tissue retraction, and consequently to phimosis and foreskin necrosis: a coronal incision to 0.5-1cm from the gland line would allow to let intact an adequate amount of reflection of skin (prepuce) bound of preputial skin reflection , maintaining good vascularity. The careful degloving with preparatory isolation of the dissection plan between dartos and Buck's fascia, can reduce vascular trauma of the fascia, minimizing bleeding and ensuring tissue vitality. Moreover, execution of only two hydraulics erections, after degloving and after correction, causes a minimal tissue stress. CONCLUSIONS: Circumcision must not be considered a mandatory time in Nesbit procedure: on the contrary, mandatory is the respect of the anatomical structures surgically attacked to avoid preputial resection.

INTRODUCTION: We decided to conduct a study to investigate the presence of cytokines in the albuginea of subjects with Peyronie's disease (PD). Cytokines, as responsible for intercellular communication, maybe involved in the pathogenesis of the disease. The identification of one or more involved cytokines may, in fact, be useful in the pharmacological treatment with biologic drugs that are able to interfere with specific cytokines. MATERIALS AND METHODS: Between January 2009 and Decembre 2010 at the Clinic of Urological outpatients clinic of the Policlinico of Palermo were recruited 20 subjects with PD, mean age 62.3 years (range 51-70) and 8 subjects with congenital recurvatum penis (mean age 21.5; range 19-28), the latter used as a control group. Inclusion criteria were the criteria for operability with Nesbit corporoplasty. The albuginea specimens were used to test gene expression of pro-fibrotic and pro-inflammatory, using Real-Time PCR. They were also subjected to histological examination after fixation by staining with hematoxylin-eosin (H&E). RESULTS: Histological examination performed on samples from both groups demonstrated the absence of inflammatory cells in all patients reviewed for the study. The analysis of the expression of genes encoding IL-4 (Interleukin-4), IL-6 (Interleukin-6), IL-13 (Interleukin-13), TGF-β (Transforming Growth Factor-β1), IL-2 (Interleukin-2), IL-10 (Interleukin-10), TNF-α (Tumor Necrosis Factor-α) and IFN-γ (Interferon-γ) showed a very low level of transcripts in all samples (in some cases undetectable). The levels of cytokine transcripts examined were lower in samples from patients with PD compared with controls. CONCLUSIONS: From the results obtained, the use of biologic drugs (antibodies) againsta the cytokine does not seem to be useful in the stable phase of Peyronie's disease due to the very low concentrations of cytokines found in the tunica albuginea of the patients.
