RESUMO

To tackle the COVID-19 infodemic, we analysed 58,625 articles from 460 unverified sources, that is, sources that were indicated by fact checkers and other mis/disinformation experts as frequently spreading mis/disinformation, covering the period from 1 January 2020 to 31 December 2022. Our aim was to identify the main narratives of COVID-19 mis/disinformation, develop a codebook, automate the process of narrative classification by training an automatic classifier, and analyse the spread of narratives over time and across countries. Articles were retrieved with a customised version of the Europe Media Monitor (EMM) processing chain providing a stream of text items. Machine translation was employed to automatically translate non-English text to English and clustering was carried out to group similar articles. A multi-level codebook of COVID-19 mis/disinformation narratives was developed following an inductive approach; a transformer-based model was developed to classify all text items according to the codebook. Using the transformer-based model, we identified 12 supernarratives that evolved over the three years studied. The analysis shows that there are often real events behind mis/disinformation trends, which unverified sources misrepresent or take out of context. We established a process that allows for near real-time monitoring of COVID-19 mis/disinformation. This experience will be useful to analyse mis/disinformation about other topics, such as climate change, migration, and geopolitical developments.

RESUMO

Objectives: To assess the change of storage symptoms (SS) and their impact on quality of life in men undergoing thulium:YAG laser enucleation of the prostate (ThuLEP) for benign prostatic hyperplasia (BPH). Materials and Methods: BPH patients requiring surgery were prospectively evaluated (April 2019-October 2020). Inclusion criteria: International Prostate Symptom Score (IPSS) ≥8, maximum urinary flow rate ≤15 mL/s, and urinary retention. Exclusion criteria: previous urethral/prostatic surgery, pelvic irradiation, bladder/prostate cancer, neurogenic bladder, concomitant transurethral surgery, and active urinary tract infection. IPSS, International Continence Society-Overactive Bladder (ICIQ-OAB) and International Continence Society-Overactive Bladder Quality of Life (ICIQ-OABq) scores were gathered before surgery and 1, 3, 6, and 12 months after surgery. Results: In total, 117 men were included. Mean age was 68.0 ± 7.7 years. Mean prostate volume was 86.6 ± 34 cc. Mean IPSS subscore was 8.7 ± 3.1 and 11.7 ± 4.7 for storage and voiding symptoms, respectively. Mean ICIQ-OAB was 29.1 ± 16.8. Mean ICIQ-OABq was 80.3 ± 30.6. Voiding IPSS decreased 72.8% at 1 month, whereas the reduction of storage IPSS was 38.0%. ICIQ-OAB decreased 49.6% at 1 month. ICIQ-OABq showed a 30.0% reduction. One year after surgery, the reduction of voiding IPSS was 94.8%, ICIQ-OAB 85.5%, storage IPSS 76.7%, and ICIQ-OABq 60.5%. Urge incontinence was present in 26.5% of men at 1 month, 15.4% at 3 months, and 4.3% at 6 months. Four (3.4%) patients complained of urge incontinence 12 months after surgery. Conclusion: Both storage and voiding lower urinary tract symptoms significantly decreased after ThuLEP, but storage symptoms showed less reduction with a significant impact on patients' quality of life, particularly during the first 3 months.

RESUMO

BACKGROUND: Abdominopelvic computed tomography (CT) is widely used in the follow-up of seminoma patients after radical orchidectomy. The aim of this study was to evaluate the clinical utility of abdominopelvic computed tomography in the follow-up of patients with Stage I seminoma. METHODS: The pathological reports of all patients that have undergone radical orchidectomy in our tertiary referral center between January 2002 and January 2018 have been retrospectively reviewed. All patients with Stage I seminoma and negative serum tumor markers after radical orchidectomy were included. Patients with follow-up shorter than 12 months were excluded. Surveillance records of every patient were reviewed with regard to abdominopelvic imaging. RESULTS: Of the 133 patients who have undergone radical orchidectomy in our center, 55 had Stage I pure seminoma with normal levels of serum tumor markers after surgery. Two patients were excluded as the follow-up was inadequate. Mean follow-up was 63.2 months (IQR: 30-73). The results of 211 abdominopelvic CTs performed as part of the follow-up were reviewed. Two (3,7%) patients developed recurrence; one consisted of a scrotal lump and was diagnosed with ultrasonography (US) while the second appeared as paraaortic nodal metastasis and was diagnosed with abdominopelvic CT. The recurrence was successfully treated in both patients. A single abdominopelvic CT was useful for the detection of recurrent disease in our entire study population. No cancer specific death has been reported in the study population. CONCLUSIONS: Follow-up schedules for Stage I seminoma expose patients to potential risks of radiation-induced tumors, emotional distress and represent a significant burden for the healthcare system. The current series suggests that a better risk adapted patient-tailored follow-up program is needed in order to avoid unnecessary investigations.

RESUMO

OBJECTIVE: To investigate the incidence of infectious complications after routine office nephrostomy tube replacement (NTR) in patients that did not receive antimicrobial prophylaxis (AMP). METHODS: We prospectively enrolled all patients undergoing routine office NTR between July 2018 and September 2019. Each procedure was considered an independent event. Clinical, microbiological, demographic data were collected. AMP was exclusion criterion. All patients received a questionnaire via phone call within 3 weeks after NTR investigating fever, antibiotics use, hospital admissions. Infectious complications risk was assessed with univariate and multivariate binomial logistic regression analysis. RESULTS: One hundred forty-five routine NTRs were performed. Nineteen patients receiving AMP were excluded. Median age was 78 years (interquartile range 71-81). Charlson Comorbidity Index (CCI) score was ≥5 in 53.2% of patients, 34 had positive urine culture, none received AMP. Seventeen (13.49%) patients reported fever after procedure, 9 received antibiotic therapy while fever resolved spontaneously in 8. Three patients needed hospitalization, 2 for nephrostomy malfunction, 1 for infectious complications. At multivariate analysis only CCI score ≥3 was associated (P < .001) with increased infectious complications risk. CONCLUSION: In this study fever occurs after the 13.5% of the routine NTRs, in almost half cases resolves spontaneously rather than with oral antimicrobial therapy. Avoiding AMP before routine NTR does not expose patients to life-threatening infections.

RESUMO

Erectile dysfunction (ED) is defined as the persistent inability to achieve and/or maintain an erection for a satisfactory sexual activity. It is secondary to several organic, psychogenic, and combined causes, and represents a serious health dilemma affecting both men and their partners. The diagnostic approach to erectile dysfunction has significantly changed in the last years with the advent of phosphodiesterase-5 (PDE5) inhibitors, and with the recognition that surgical treatment of both arterial insufficiency and penile venous leak have poor long-term clinical outcomes. Although imaging modalities have diminished in importance, differentiating among causes of erectile dysfunction remains mandatory in good medical practice, and ultrasound (US) still remains the cornerstone of the diagnostic workup. US provides an objective, minimally invasive evaluation of penile hemodynamics. Moreover, it provides an excellent depiction of the penile anatomy and of its changes in pathological conditions such as in patients with Peyronie's disease, priapism, and posttraumatic erectile dysfunction.

RESUMO

PURPOSE: No questionnaire is currently available to evaluate sexual function after male-to-female gender affirming surgery. Such a limit leads to a suboptimal evaluation in postoperative sexual function in these patients. We developed and validated a new questionnaire, the oMtFSFI (operated Male-to-Female Sexual Function Index), for assessing sexual function in male-to-female patients after surgery. MATERIALS AND METHODS: A panel of experts in gender dysphoria defined the main content areas to be assessed, including genital self-image, desire, arousal, lubrication, orgasm, satisfaction and sexual pain. After a pretest on 10 patients the oMtFSFI was applied in the main study to 65 operated male-to-female patients, recruited at 7 Italian centers, and 57 women. The participants provided self-ratings on online oMtFSFI, Female Sexual Function Index, Beck Depression Inventory for Primary Care and Short Form Health Survey questionnaires. Operated male-to-female patients completed the oMtFSFI twice, 4 weeks apart. RESULTS: Principal component analysis performed on self-ratings provided by operated male-to-female patients on oMtFSFI items yielded a 3-domain structure of sexual dissatisfaction, sexual pain and genital self-image. The 3 domains were internally consistent and test-retest reliable. Convergent associations with Female Sexual Function Index scales emerged for sexual dissatisfaction and sexual pain but not for genital self-image. Male-to-female patients reported lower sexual function levels than cisgender women. CONCLUSIONS: The present preliminary results support reliability and psychometric validity of the oMtFSFI in the assessment of key sexual function domains in transgender women, further revealing that genital self-image represents an assessment area to be considered in male-to-female patients, in addition to domains that are salient for cis women as well.

RESUMO

INTRODUCTION: Stuttering priapism is a variation of ischemic priapism, generally transient and self-limiting, occurring during sleep and lasting less than 3-4 hours. It may progress to episodes of complete ischemic priapism in approximately one third of cases, necessitating emergent intervention. EVIDENCE ACQUISITION: This review aims to provide an up-to-date picture of the pathophysiology and management of stuttering priapism. A search using Medline and EMBASE for relevant publications using the terms "priapism", "stuttering", "diagnosis", "treatment", "fibrosis", was performed. EVIDENCE SYNTHESIS: Stuttering priapism shares its etiologies with ischemic priapism and a large number of diseases or clinical situations have risk association for developing the disorder. The most common causes are sickle cell disease or other hematologic and coagulative dyscrasias especially in children. In the adult population, idiopathic priapism occurring without any discernible cause is considered to be the most common form in adults. The medical management of priapism represents a therapeutic challenge to urologists. Unfortunately, although numerous medical treatment options have been reported, the majority are through small trials or anecdotal reports. Understanding the underlying pathophysiology and understanding the current and emerging future agents and therapeutic options are mandatory in order to provide the best solution for each patient. CONCLUSIONS: The goal of management of priapism is to achieve detumescence of the persistent erection in order to preserve erectile function. To achieve successful management, urologists should address this emergency clinical condition. In the present article, we review the diagnosis and clinical management of the three types of priapism.

RESUMO

Vaginoplasty in Male to Female (M to F) transgenders is a challenging procedure, often accompanied by numerous complications. Nowadays the most commonly used technique involves inverted penile and scrotal flaps. In this paper the data of 47 M to F patients who have undergone sex affirmation surgery at the Department of Urology of the University of Trieste, Italy since 2014, using our modified vaginoplasty technique with the "Y" shaped urethral flap, have been retrospectively reviewed. Moreover, a non structured review of the literature with regards to short and long-term complications of vaginoplasty has been provided. All patients followed a standardized neo-vaginal dilation protocol. At follow up 2 patients were lost. At 12 months 88.9% of patients (40/45) were able to reach climax, 75.6% (34/45) were having neo-vaginal intercourses and median neo-vaginal depth was 11 cm (IQR 9-13.25): no statistically significant decrease in depth was found at follow up. Only one patient was dissatisfied with aesthetic appearance at 12 months. Our technique provided excellent cosmetic and functional results without severe complications (Clavien-Dindo ≥ 3). The review of the literature has highlighted the need to standardize a postoperative follow up protocol with particular regard to postoperative dilatation regimen. Further, larger randomized clinical trials are pending to draw definitive conclusions.

RESUMO

INTRODUCTION: After extracorporeal lithotripsy (SWL), a spontaneous expulsion of fragments is often reported. The aim of this study is to demonstrate the presence of a stone free status or the presence of clinically insignificant residual fragments (CIRFs, defined as "asymptomatic, noninfectious, ≤ 3 mm fragments") in people with undetected spontaneous expulsion. MATERIALS AND METHODS: Between May and September 2017, we performed a total of 87 treatments. The device used was a Storz Medical Modulith® SLK. All the patients were treated in prone position to reduce respiratory movements and underwent sonography before and four to eight weeks after the treatment. An in line ultrasound targeting was possible with all the stones. People lost to follow up or with ureteral stones were excluded. Patients were divided in groups according to gender, previous treatments, stone diameter and position. RESULTS: We enrolled 73 patients. 57 patients had a single stone and 16 multiple stones. A mean number of 3044 shock waves was administered with a maximum average energy of 0.68mj/mmq. At follow up, 41 patients (56.2%) were found stone free or with CIRFs. The association between undetected expulsion and the presence of CIRFs is considered to be not statistically significant (p = 0.89). Among patients with CIRFs, 25/41 didn't report expulsion. Taking in account the groups our population was divided in, according to gender (p = 0.36), previous treatments (p = 0.44), stone diameter (p = 0.28) and stone position (p = 0.35), the association between undetected spontaneous expulsion and presence of CIRFs was never statistically significant. CONCLUSIONS: An undetected spontaneous expulsion of stone fragments could not be considered a sign of SWL treatment failure. The association between undetected expulsion and presence of CIRFs is never statistically significant if gender of the patients, previous treatments, stone diameter and stone position are considered.

RESUMO

INTRODUCTION: We analyzed efficacy and complications of extracorporeal shock wave lithotripsy (SWL) and analgesia requirement during the treatment in two groups of patients treated with different lithotripters. MATERIALS AND METHODS: The patients treated were 189, 102 between September 2016 and April 2017 with HMT Lithotron® LITS 172, electrohydraulic, and 87 between May and September 2017 with Storz Medical Modulith® SLK, electromagnetic. The main differences between the lithotripters are: type of energy source, patient position, frequency and number of shock waves. All the patients underwent sonography before and four to eight weeks after the treatment. The targeting was sonographic for renal stones and X-ray for ureteral stones. All the patients received Ketorolac before the treatment with a supplement of Pethidine if needed. People lost to follow-up and with incomplete data were excluded. RESULTS: We enrolled 173 patients, 94 treated with the electrohydraulic lithotripter and 79 with the electromagnetic one. 43 patients (54%) in the electromagnetic group and 31 (33%) in the electrohydraulic group were stone free or presented clinically insignificant residual fragments (CIRFs), defined as asymptomatic, noninfectious, ≤ 3 mm. The association between CIRFs and the kind of lithotripter was statistically significant (p = 0.004). An increased need for analgesia was found in 14.9% of patients in the electromagnetic group and in 81% of patients in the electrohydraulic group (p < 0.001). The access to emergency room (intractable pain, kidney failure, fever, Steintrasse) after the treatment was similar in the two groups (p = 0.37). CONCLUSIONS: The best results in stones fragmentation and less analgesia requirement were demonstrated in the electromagnetic lithotripter group. No differences were demonstrated considering the need for emergency room after the treatment.

RESUMO

On cross-sectional imaging studies performed for other indications, incidental discovery of renal lesions is not uncommon. In daily use, grey-scale ultrasonography (US) and conventional Doppler modes are often the modality of choice for the initial assessment. While simple cysts are fully characterized with US, other lesions require further characterization, which is traditionally obtained by multiphase imaging, such as contrast-enhanced CT and MRI. Contrast-enhanced ultrasound (CEUS) has become a powerful additional tool for imaging renal lesions. With its lack of nephrotoxicity, the absence of ionizing radiation, and the ability to evaluate the enhancement pattern of renal lesions quickly and in real- time, CEUS has unique advantages over traditional modes. Established applications are differentiation between solid tumours, pseudolesions, and complex cysts; characterization of complex cysts with different malignant potential, and evaluation of tumor ablation. Microbubble contrast agents are safe. Adverse reactions are rare. This article provides an overview of the current clinical applications of CEUS in characterizing renal masses, discussing advantages and limitations. The aim is to provide the framework for sonologists to make informed decisions regarding this emerging imaging test in appropriate circumstances.

RESUMO

BACKGROUND: The aim of this study was to assess the efficacy of emergency extracorporeal shockwave lithotripsy (eSWL) as first-line treatment in patients with acute colic due to obstructive ureteral stone. METHODS: Seventy-four patients were randomized to emergency SWL within 12 hours (eSWL group) and deferred SWL later than 3 days (dSWL group). Follow-up included ultrasound, KUB (kidney-ureter-bladder) radiography and CT (computed tomography) scan at 24 hours, 7 days, 1 and 3 months from the treatment. When necessary, repeated SWL (re-SWL) or ureteroscopy (auxiliary-URS) was performed. Preoperative and postoperative data were compared and stone free rates (SFR) and efficiency quotients (EQ) were evaluated. Analyses were performed using SAS software. RESULTS: Complete data of 70 patients were collected. 36 underwent eSWL and 34 dSWL. The mean patient age was 48.7. Mean stone size was 9.8 mm (CI 95%: 8.9-10.8). 25 (35.7%) were proximal and 45 (64.3%) distal. Mean SWL energy was 19.2 kV (CI 95%: 18.5-19.9) and mean number of shocks was 2657 (CI 95%: 2513-2802). eSWL patients needs less auxiliary-URS than dSWL patients (13.9% vs. 44.1%, P=0.039) and less re-SWL sessions (8.3% vs. 32.4%, P=0.093). SFR at 24 hours was 52.8% and 11.8% (P<0.001) and the EQ at 3 months was 79.1% and 57.5% in the eSWL and dSWL group respectively. Patients from the dSWL group spent more time in the hospital (2.21 vs. 1.36 days, P=0.046) and complication rates between the two groups were similar. CONCLUSIONS: eSWL is a safe procedure and delivers high SFR even within 24 hours especially for <10 mm stones. It is able to reduce the number of auxiliary procedures and hospitalization.

RESUMO

OBJECTIVE: To describe the surgical outcomes of ileal vaginoplasty in transgender women and patients with disorders of sex development (DSD). PATIENTS AND METHODS: Transgender women and patients with DSD, who underwent ileal vaginoplasty at the VU University Medical Center Amsterdam, University Hospital Trieste, University Hospital Essen, and Belgrade University Hospital, were retrospectively identified. A chart review was performed, recording surgical technique, intraoperative characteristics, complications, and re-operations. RESULTS: We identified a total of 32 patients (27 transgender and five non-transgender), with a median (range) age of 35 (6-63) years. Ileal vaginoplasty was performed as the primary procedure in three and as a revision procedure in the remaining 29. The mean (sd) operative time was 288 (103) min. The procedure was performed laparoscopically (seven patients) or open (25). An ileal 'U-pouch' was created in five patients and a single lumen in 27. Intraoperative complications occurred in two patients (one iatrogenic bladder damage and one intraoperative blood loss necessitating transfusion). The median (range) hospitalisation was 12 (6-30) days. Successful neovaginal reconstruction was achieved in all. The mean (sd) achieved neovaginal depth was 13.2 (3.1) cm. The median (range) clinical follow-up was 35 (3-159) months. In one patient a recto-neovaginal fistula occurred, which lead to temporary ileostomy. Introital stenosis occurred in four patients (12.5%). CONCLUSION: Ileal vaginoplasty can be performed with few intra- and postoperative complications. It appears to have similar complication rates when compared to sigmoid vaginoplasty. It now seems to be used predominantly for revision procedures.

RESUMO

Multiparametric US is increasingly recognized as a valuable problem-solving technique in scrotal pathologies. Compared to conventional Doppler modes, contrast-enhanced ultrasonography (CEUS) has higher sensitivity in assessing the presence or absence of flows, and to improve differentiation between poorly vascularized tumors and non-neoplastic, avascular lesions. Characterization of benign and malignant complex cysts is improved. In trauma patients, CEUS can help evaluating the viability of testicular parenchyma. In patients with severe epididymo-orchitis, it allows unequivocal assessment of post-inflammatory ischemic changes and abscess formation. CEUS does not add significantly to conventional Doppler modes in spermatic cord torsion. Attempt of differentiating benign and malignant tumors remains a research tool. In the clinical practice, elastography has a limited role for tumor characterization. The majority of malignant tumors are stiff at elastography, but they may display soft areas, or appear globally soft. A quantitative evaluation of testicular stiffness is feasible using shear-wave elastography. Potential clinical applications for elastographic modes could include work-up of infertile patients.

RESUMO

OBJECTIVE: To investigate the role of MRI in the evaluation of both the new female anatomy and complications in male-to-female sex reassignment surgery (MtF-SRS). METHODS: 71 consecutive patients with MtF-SRS had 74 MRI [age range, 21-63 years; mean (±standard deviation) age, 36 ± 10 years; median age, 37 years]. In 47 patients, MRI was performed to rule out early post-operative complications after gender conversion (n = 40), vaginoplasty (n = 6) or remodelling of the labia majora (n = 1). In 27 patients, MRI was performed 1-20 years after MtF-SRS for late post-operative complications, pain or dysuria, inflammatory changes or poor cosmetic outcome. Three patients had MRI both before and after the operation. RESULTS: MRI allowed investigation of the new female anatomy in all cases. Soon after MtF-SRS, a small amount of blood was identified in all patients around the neoclitoris, urethral plaque and labia. Post-operative complications were clinically significant fluid collections (n = 5), labial abscesses (n = 2), severe cellulitis (n = 3), partial neovaginal prolapse (n = 3), focal necrosis and dehiscence of the vaginal wall (n = 2) and hypovascularization of the neoclitoris (n = 1). After ileal vaginoplasty, three patients developed clinically insignificant haematomas, one a large rectovaginal fistula with dehiscence of the intestinal anastomosis and bowel perforation (n = 1). In the 27 patients investigated 1-20 years after MfF-SRS, MRI demonstrated cavernosal remnants (n = 10), spared testis (n = 1) neovaginal strictures (n = 8), fistulas and abscesses (n = 3) and prolapse (n = 2). Three of these patients also had fibrotic changes. In the remaining three patients, no pathological features were identified. CONCLUSION: After genital reconfiguration, MRI allows assessment of the post-operative anatomy and of post-operative complications.

RESUMO

INTRODUCTION: Iatrogenic ureteral injury (IUI) is a serious complication that can occur during abdominal or pelvic operations with a reported frequency in literature of approximately 0.3-1.5%. Moreover, the number of iatrogenic ureteric injuries has increased markedly during the past two decades, partly because of the introduction of laparoscopy and the overall increase in surgical procedures. MATERIAL AND METHOD: The present systematic review was set up to compare the incidence of IUI between laparoscopic and open colectomies. The study also assessed the features of the ureteric injuries and their prevention and management. We conducted a search of the literature for prospective and randomized clinical trials presenting a comparison between laparoscopic and open colorectal resections performed for any indication starting from 2003 to 2015. RESULTS: After an initial moderate increase in incidence of IUIs, with growing experience in laparoscopic surgery, ureteral injuries not seem to be more in laparoscopic surgery than conventional surgery. Many surgeons and gynecologists agree that prophylactic ureteral catheterization may reduce the chance of IUIs. CONCLUSIONS: Ureteral injury is especially difficult to detect during laparoscopic operations, and the symptoms of ureteric injury may develop either acutely or more insidiously, depending on the mechanism of injury. These injuries, if recognized late, can result in significant morbidity with loss of renal function. Early recognition and immediate repair of ureteral injuries during the same procedure is highly desirable. A ureteral injury not recognized and treated during the same procedure may require a temporary diverting nephrostomy and secondary surgery with increased morbidity. KEY WORDS: Colectomy, Injury, Laparoscopy, Ureter.

RESUMO

We report a case of polyorchidism, a rare congenital anomaly, frequently discovered by chance. At current knowledge is still not defined which is the best clinical and therapeutic approach as well the best follow- up scheme due to the unclear malignant potential and rate of complications if a conservative approach is used. MRI (Magnetic Resonance Imaging) seems to be a good method to discriminate this mass from others pathological findings but there is still not enough evidence to standardize the procedure.

RESUMO

OBJECTIVE: We report a case of enucleation of a non-palpable right testicular lesion found incidentally at testicular ultrasonography during investigations in a patient with azoospermia. MATERIALS AND METHODS: In 2011 bilateral hypoechoic nonpalpable testicular lesions (5 mm and 3 mm to the right, 3 mm to the left) were found in a 28 years old patient, during diagnostic investigations for azoospermia. In March 2016, ultrasonography showed that the diameter of the right major nodule had grown to 12 mm, characterized by increased vascularization and increased texture. Blood exams showed serum FSH above normal levels with negative oncologic markers. The patients underwent surgical enucleation of the right nodule under ultrasonography guidance. RESULTS: In post operative day 1 a control ultrasonography documented the disappearance of the lesion. Hystopathologic examination diagnosed a Leydig cell tumor, with negative surgical margins. The patient is in good clinical conditions and is under periodic ultrasonographic follow up. CONCLUSION: Organ sparing surgery represent a good therapeutic option for little intraparenchymal lesions, mostly in young patients in which is preferable to preserve fertility. Intraoperatory ultrasonography represent an important tool for the localization of the lesion.
