RESUMO

STUDY QUESTION: When is the investigation and treatment of midline prostatic cysts (MPC) of clinical value in the work-up of males of infertile couples? SUMMARY ANSWER: With a prevalence of 10.2% in infertile men, MPC should be investigated according to a seminal algorithm detecting a MPC volume >0.117 ml, which may impair semen parameters, and could be treated to improve sperm count and achieve natural pregnancy. WHAT IS KNOWN ALREADY: MPC are frequent and are considered a correctable cause of male infertility. However, they have been poorly investigated in an infertility setting. In addition, no study has investigated clinical and ultrasound (US) characteristics of men with MPC. STUDY DESIGN, SIZE, DURATION: A cross-sectional analysis was carried out of 693 consecutive subjects consulting for couple infertility from September 2012 to March 2017. As a control group, 103 age-matched healthy, fertile men were studied. Furthermore, a longitudinal evaluation of 11 infertile men undergoing trans-rectal ultrasonically-guided cyst aspiration (TRUCA), semen analyses 1 and 3 months after TRUCA and a follow-up 1 year after TRUCA to assess natural pregnancy were performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: All subjects underwent, in our outpatient clinic, clinical, hormonal, scrotal and transrectal US evaluation and semen analysis within the same day. Of 693 males of infertile couples, 648 (37.1 ± 7.9 years, mean+SD) without genetic abnormalities were studied, along with 103 fertile men (36.6 ± 5.0 years). Eleven infertile men underwent TRUCA and were followed-up as reported above. MAIN RESULTS AND THE ROLE OF CHANCE: A MPC was present in 66/648 (10.2%) males of infertile couples and in 6/103 (5.8%) fertile men. MPC occurrence and volume were higher in patients with severe oligo- or azoospermia than in fertile men (all P < 0.05). Infertile men with a MPC showed a lower seminal volume and sperm count and a higher prevalence of azoospermia than the rest of the infertile sample or fertile men, and a higher frequency of US signs suggestive of ejaculatory duct obstruction. MPC volume was negatively associated with total sperm count (r = -0.452, P < 0.0001). In fertile men, the highest MPC volume was 0.117 ml, suggesting it as a biological threshold not compromising semen quality. In infertile men, using receiver operating characteristic curve analyses, a MPC volume >0.117 ml identified subjects with severe oligo- or azoospermia with an overall accuracy of ~75% (both P < 0.005). Eleven men with infertility, semen abnormalities and large MPC (>0.250 ml) underwent TRUCA, which led to sperm count improvement in all patients 1 month after surgery. Three months after TRUCA a lower sperm count and a higher MPC volume than 2 months before were observed (P < 0.005 and P < 0.05, respectively), although improved when compared to baseline. After TRUCA a natural pregnancy occurred in four couples. Finally, we propose an algorithm, based on semen parameters, useful in identifying a MPC in males of infertile couples. LIMITATIONS, REASONS FOR CAUTION: Although in line with the sample size of previous studies (n = 7-20), the number of infertile men with MPC evaluated longitudinally after treatment is limited (n = 11). In addition, although a MPC volume >0.117 ml can negatively affect the sperm count, only MPC > 0.250 ml have been treated in this study. WIDER IMPLICATIONS OF THE FINDINGS: First, the algorithm proposed is easy to use and useful for selecting patients who can benefit from a prostate US in the infertility work-up. Second, a MPC volume ≤0.117 ml may not impair semen quality, while a larger volume can lead to severe oligo- or azoospermia and could be treated. Third, TRUCA is effective, and simpler and less invasive than other surgical techniques for MPC treatment. Finally, since the MPC can increase in size and sperm count decrease over time after TRUCA, semen cryopreservation should be considered 1 month after TRUCA.

RESUMO

Infertility occurs in up to 54% of men with bilateral undescended testes. Orchiectomy is considered the best therapeutic approach, especially when cryptorchidism is diagnosed in adulthood, due to a high risk of malignancy. A 33-year-old man was referred with a clinical presentation of empty scrotum and an ultrasonography and magnetic resonance imaging evaluation of intra-abdominal bilateral cryptorchidism. Follicle-stimulating hormone was 23.20 IU/L, luteinising hormone was 14.10 IU/L, total testosterone was 12.1 nmol/L, and 17-beta-oestradiol was 0.16 nmol/L. Semen analysis showed absolute azoospermia. Tumour marker levels were in the normal range. Testicular volume was 4.0 ml for right testis and 4.6 ml for left testis. The patient underwent a laparoscopy bilateral orchiectomy and subsequently a testicular sperm extraction (TESE), in the purpose to finding mature spermatozoa. The biological examination revealed the presence of immature sperm cells, not efficient for a cryopreservation. The histologic analyses show a pattern of Sertoli cell-only syndrome and maturation arrest. TESE might be a good option for patients with absolute azoospermia and cryptorchidism, especially if bilateral. The procedure, performed after orchiectomy, is safe and does not have any impact on patient's health, although it is important to clarify the very low potential of sperm recovery.

RESUMO

Azoospermia can be diagnosed in about 10%-15% of the infertile male population. To overcome the problem of failure to produce spermatozoa in the ejaculate in patients with nonobstructive azoospermia (NOA), testicular sperm extraction (TESE) may be performed to find the focal area of spermatogenesis. A 47-year-old man with NOA presented for treatment of secondary couple infertility. The patient underwent a first TESE 7 years earlier with cryopreservation, and an intracytoplasmic sperm injection-embryo transfer ended in a term pregnancy. He reported a history of repeated testicular traumas. At the present time, a complete medical workup was carried out, including clinical history, general and genital physical examination, scrotal and transrectal ultrasounds. Hormone measurements showed follicle-stimulating hormone level of 42.7 IU/L, luteinising hormone of 11.4 IU/L, total testosterone of 2.6 ng/ml and right and left testicular volume, respectively, of 4 and 3.9 ml. He underwent a second TESE, with successful sperm retrieval and cryopreservation. The histological pattern was hypospermatogenesis. In cases of extreme testicular impairment, although in the presence of very high follicle-stimulating hormone value and small testicular volume, estimating poor sperm recovery potential, the integration of clinical and anamnestic data, could help the surgeon to practise the more appropriate method of treatment.

RESUMO

Sickle cell disease (SCD) is an inherited hemoglobin disorder characterized by the occlusion of small blood vessels by sickle-shaped red blood cells. SCD is associated with a number of complications, including ischemic priapism. While SCD accounts for at least one-third of all priapism cases, no definitive treatment strategy has been established to specifically treat patients with SC priapism. The aim of this systematic review was to assess the efficacy and safety of contemporary treatment modalities for acute and stuttering ischemic priapism associated with SCD. The primary outcome measures were defined as resolution of acute priapism (detumescence) and complete response of stuttering priapism, while the primary harm outcome was as sexual dysfunction. The protocol for the review has been registered (PROSPERO Nr: CRD42020182001), and a systematic search of Medline, Embase, and Cochrane controlled trials databases was performed. Three trials with 41 observational studies met the criteria for inclusion in this review. None of the trials assessed detumescence, as a primary outcome. All of the trials reported a complete response of stuttering priapism; however, the certainty of the evidence was low. It is clear that assessing the effectiveness of specific interventions for priapism in SCD, well-designed, adequately-powered, multicenter trials are strongly required.

RESUMO

Surgical treatments for ischemic priapism (IP) include shunts or penile implants. Non-ischemic priapism (NIP) is usually the result of penile/perineal trauma causing an arterial fistula and embolisation may be required. We conducted a systematic review on behalf of the EAU Sexual and Reproductive health Guidelines panel to analyse the available evidence on efficacy and safety of surgical modalities for IP and NIP. Outcomes were priapism resolution, sexual function and adverse events following surgery. Overall, 63 studies (n = 923) met inclusion criteria up to September 2021. For IP (n = 702), surgery comprised distal (n = 274), proximal shunts (n = 209) and penile prostheses (n = 194). Resolution occurred in 18.7-100% for distal, 5.7-100% for proximal shunts and 100% for penile prostheses. Potency rate was 20-100% for distal, 11.1-77.2% for proximal shunts, and 26.3-100% for penile prostheses, respectively. Patient satisfaction was 60-100% following penile prostheses implantation. Complications were 0-42.5% for shunts and 0-13.6% for IPP. For NIP (n = 221), embolisation success was 85.7-100% and potency 80-100%. The majority of studies were retrospective cohort studies. Risk of bias was high. Overall, surgical shunts have acceptable success rates in IP. Proximal/venous shunts should be abandoned due to morbidity/ED rates. In IP > 48 h, best outcomes are seen with penile prostheses implantation. Embolisation is the mainstay technique for NIP with high resolution rates and adequate erectile function.

RESUMO

BACKGROUND: Nowadays, serodiscordant couples (SDCs) with human immunodeficiency virus (HIV) or hepatitis C virus (HCV)-infected men have the chance to conceive safely, giving birth with a minimum risk of cross-infection. OBJECTIVE: To assess the impact of male HIV and HCV infection on the assisted reproductive technologies (ART) outcomes in SDCs, with HIV or HCV seropositive men and negative partners. MATERIALS AND METHODS: Of 153 couples: 24 in Group 1 (HIV-seropositive men), 60 in Group 2 (HCV-seropositive men) and 69 in Group 3 (controls). Sperm-washing procedure was performed using a three-step system. Fresh ICSI cycles were carried out in HIV SDCs, HCV SDCs and controls. Seminal parameters, fertilization rate (FR), cleavage rate (CR), pregnancy rate per cycle (PR/C), miscarriage rate, implantation rate (IR) and live birth rate were evaluated. RESULTS: All the seropositive men have undetectable viral loads at the time of insemination, and both partners were free from co-morbid infections. The median number of embryos transferred was 2.0 (IQR 1.0-3.0), with no differences among groups. FR was significantly reduced in HIV and HCV SDCs compared to the controls (66%, 61% and 75%, respectively; p < 0.01). CR was similar between groups (p = 0.3). IR was 12.1%, 11.1% and 14.1%, respectively, in the three groups (p = 0.30). PR/C was 21.7%, 17.6% and 20.2% in HIV, HCV and controls, respectively. Live birth rate per cycle was 17.4%, 15.7% and 15.9%, respectively. There were no significant differences in clinical pregnancies per cycle, as well as miscarriages and live births (p = 0.30; 0.30; 0.60, respectively). CONCLUSIONS: The sperm-washing technique with ICSI may generate a promising way to improve pregnancy outcomes and to reduce the risk of viral transmission in these couples. In this setting, we can correctly counsel HIV- and HCV-infected men of SDCs with regard to the likelihood of father their own biological child.

RESUMO

Peyronie's disease (PD) is a common condition which results in penile curvature making sexual intercourse difficult or impossible. Collagenase clostridium histolyticum (CCH) is the first licensed drug for the treatment of PD and is indicated in patients with palpable plaque and curvature deformity of at least 30° of curvature. However, only few monocentric studies are available in the current literature and this is the first national multicentric study focusing on this new treatment. In five Italian centres, 135 patients have completed the treatment with three injections of CCH using Ralph's shortened modified protocol. The protocol consisted of three intralesional injections of CCH (0.9 mg) given at 4-weekly intervals in addiction to a combination of home modelling, stretching and a vacuum device on a daily basis. An improvement in the angle of curvature was recorded in 128/135 patients (94.8%) by a mean (range) of 19.1 (0-40)° or 42.9 (0-67)% from baseline (p < 0.001). There was also a statistically significant improvement in all IIEF and PDQ questionnaires subdomains (p < 0.001 in all subdomains). This prospective multicentric study confirms that the three-injection protocol is effective enough to achieve a good result and to minimize the cost of the treatment.

RESUMO

BACKGROUND: The 2013-2016 Ebola virus disease (EVD) outbreak showed a lack of diagnostic point-of-care methods. Currently, EBOV diagnosis relies on quantitative reverse-transcription-PCR (RT- qPCR), highly specific and sensitive, but requiring skilled personnel and well-equipped laboratories. In field settings, these factors and others, such as samples' time of collection and transportation, determine a prolonged turnaround-time to final results. In outbreak scenarios, a rapid and transportable method could eliminate issues of cohorting suspected and actual EVD patients for lack of diagnostic certainty. The aim of this study was the field evaluation of the new fast, easy-to-use and reliable RT-qPCR assay and platform for EBOV detection, developed in the framework of the EbolaMoDRAD project by CLONIT S.r.l. and STMicroelectronics S.r.l. STUDY DESIGN: We evaluated its performance during the outbreak and in further studies in the EVD laboratory at the Princess Christian Maternity Hospital (PCMH) in Freetown (Sierra Leone) run by Emergency NGO and the Italian National Institute for Infectious Diseases (INMI). The assay was tested on residual aliquots of clinical specimens from EBOV-positive or -negative patients (n=116, EVD prevalence 37%). RESULTS AND CONCLUSION: Overall, the test was very easy-to-use and the instrument was robust and reliable in field-settings. The sensitivity of the assay was 100% and the specificity was 98.63% (95%CI: 96.34-100.92%). The positive and negative predictive values were 97.73 (95%CI:94.77-100.68%) and 100%, respectively. The high sensitivity and specificity of this new assay indicate that it is promising for laboratory diagnosis, especially in resource-limited settings.

RESUMO

OBJECTIVE: The Prostate Cancer Specific Quality of Life Instrument (PROSQOLI) is a measure of health-related quality of life (HRQoL) in advanced hormone-resistant prostate cancer. In this study, we aimed at performing a cross-cultural adaptation and validation of the Italian version of the PROSQOLI. PATIENTS AND METHODS: The original version of the PROSQOLI underwent several turnarounds of translations. A total of 472 patients treated with radical prostatectomy, radiotherapy or medical therapy were enrolled for the validation of the questionnaire. The PROSQOLI was administered together with the SF-12. Reliability indexes were calculated by using Cronbach alpha. To evaluate the validity of the construct, relationships between PROSQOLI and SF12 were assessed. The ANOVA test was used to evaluate the differences between groups of patients who had received different treatments. RESULTS: The reliability coefficient was 0.91. Item-to-total correlation indices were in most cases >0.70. The correlation between the scores of the PROSQOLI and those of the SF-12 questionnaire was high (r=0.8139, p<0.0001). The ANOVA test showed significant differences between groups (p<0.01) based on age, recurrence risk and treatment. CONCLUSIONS: The adaptation process showed that the PROSQOLI Italian version has high reliability and presents both convergent and discriminant validity. This version of the tool can be used to assess HRQoL in Italian men who underwent radical treatment for advanced prostate cancer.

RESUMO

A 2-year-old male Labrador Retriever was presented for sudden abdominal distension. Abdominal ultrasonography revealed abundant abdominal fluid and a hepatic mass, which was removed by total lobectomy. Histologic evaluation of the mass supported a vascular hepatic hamartoma. Vascular hamartomas are rare malformations in animals and only two cases have been reported in the dog. This is the first recorded case of a canine vascular hepatic hamartoma treated surgically and having a successful long-term outcome.

RESUMO

AIMS: Cutaneous manifestations are frequently reported in association with drug use. The aim of this study was to analyse the skin reactions reported to the spontaneous surveillance systems of four Italian regions (Friuli Venezia Giulia, Lombardy, Sicily and the Veneto), and correlate the reports with estimated drug consumption during the same period, paying particular attention to the reactions to antimicrobial agents and nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS: All of the adverse drug reactions (ADRs) reported spontaneously between January 1996 and December 1997 to the surveillance systems of four Italian regions (a total population of about 20 million people) were analysed by a panel of experts including dermatologists. On the basis of the Critical Term List of the World Health Organization (WHO), the reactions were classified as either serious or nonserious events. Drug consumption was expressed as a daily defined dose (DDD)/1000 inhabitants/day. RESULTS: A total of 2224 adverse skin reaction reports (44.7% of all of the reported ADRs) were identified, making a reporting rate of about 5.5 per 100 000 inhabitants/year. The female/male ratio was 1.58, and the reporting rate progressively increased with age. The drug categories with the highest number of cutaneous reactions were antimicrobials, followed by NSAIDs, analgesics and radiology contrast media. There was a total of 372 (16.9%) serious reaction reports, the most frequent being angioedema (171 cases), erythema multiforme (68 cases) and photosensitivity (37 cases). Co-trimoxazole, followed by the cephalosporins and fluoroquinolones, were associated with the highest consumption-related reporting rate among the antimicrobials, and aspirin and dipyrone among the NSAIDs and analgesics. CONCLUSIONS: Spontaneous reports from four Italian regions revealed that the skin was the organ most frequently affected by ADRs. The paper shows the validity of a regional decentralized system in Italy.
