    Premature ejaculation (PE) is the most common male sexual disorder. We compared pelvic floor muscle rehabilitation to on-demand treatment with the selective serotonin reuptake inhibitor dapoxetine in 40 men with lifelong PE (baseline intra-vaginal ejaculatory latency time (IELT) =1 min). Subjects were randomized into the following two treatment groups: (1) PFM rehabilitation or (2) 30 or 60 mg of on-demand dapoxetine. Total treatment time for both groups was 12 weeks, at the end of which, IELT mean values were calculated to compare the effectiveness of the two different therapeutic approaches. At the end of treatment, 11 of the 19 patients (57%) treated with rehabilitation were able to control the ejaculation reflex, with a mean IELT of 126.6 sec (range: 123.6152.4 sec). In the dapoxetine group, after 12 weeks of therapy, 5 of 8 (62.5%) patients in the 30 mg subgroup and five of seven (72%) in the 60 mg subgroup had an IELT >180 sec (mean: 178.2 and 202.8 sec, respectively). The results obtained in the group treated with pelvic floor rehabilitation are promising, and this treatment represents an important cost reduction if compared to dapoxetine on-demand treatment. The present study confirms the data that are previously available in the literature on the efficacy and safety of the new inhibitor of serotonin reuptake, dapoxetine, as well as proposes and evaluates a new type of physical treatment that may be a viable therapeutic option for treatment of PE

    A novel combination of triple metachronous malignancies of the kidney, oropharynx and prostate. A case report

    Synchronous or metachronous malignancies are a rare event, with an incidence rate that increases with age. The present study reports the case of a 70-year-old Caucasian male who was referred to the outpatient office of the Urology Unit, Sapienza University of Rome (Latina, Italy) due to lower urinary tract symptoms. An abdominal ultrasound investigation was performed that demonstrated the presence of a right renal mass. The patient underwent right radical nephrectomy, which resulted in the definitive diagnosis of clear cell type renal cell carcinoma. The patient was eventually diagnosed with triple primary metachronous cancer consisting of renal clear cell carcinoma, prostate adenocarcinoma and squamous cell carcinoma of the oropharynx (palatine tonsil). To the best of our knowledge, this combination of primary neoplasms has not previously been documented

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
