What is the effectiveness of surgical and non-surgical therapies in the treatment of ischemic priapism in patients with sickle cell disease? A systematic review by the EAU Sexual and Reproductive Health Guidelines Panel

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.

Surgical and minimally invasive treatment of ischaemic and non-ischaemic priapism: a systematic review by the EAU Sexual and Reproductive Health Guidelines panel

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.

Foveal Triangular Fibrocartilage Complex Tears: Recognition of a Combined Tear Pattern

PURPOSE

Triangular fibrocartilage complex (TFCC) injuries are categorized most commonly by the Palmer and the Atzei and Luchetti classifications. Combined tears are reported less frequently, and the classification of these tears is unclear. In this study, we present a series of patients with combined central disc and foveal TFCC tears that do not fit into either of these classifications.

METHODS

Seventeen patients from 2 institutions presented with a combined central and foveal TFCC tear, confirmed by wrist arthroscopy between September 2017 and December 2020. Patient demographics, injury mechanism, associated injuries, clinical findings, magnetic resonance imaging results, surgeon description of tears, and treatment rendered were evaluated.

RESULTS

Patients were predominantly female (76%). Mean age was 40 years with a bimodal age distribution (7/17 patients <35 and 10/17 >45 years). Eleven patients (65%) sustained the injury from a fall. All had some degree of distal radioulnar joint (DRUJ) instability on clinical examination and almost half (8/17) had a history of a distal radius or ulnar styloid fracture during the initial injury. The foveal tear was confirmed by direct visual assessment and a positive hook test result; a suction test result commonly was positive as well. All patients underwent debridement of the central tear, and 16 of 17 underwent foveal TFCC repair with 1 having an irreparable tear.

CONCLUSIONS

We present a series of patients with combined central disc and foveal TFCC tears, a pattern that does not fit current classification schemes. All patients exhibited some degree of instability of the DRUJ and almost half had a history of distal radius or ulnar styloid fracture. Identification of a central tear of the TFCC, together with even subtle DRUJ instability, should lead to consideration of a coexistent foveal tear.

Andrological effects of SARS-Cov-2 infection: a systematic review and meta-analysis

PURPOSE

The short- and long-term andrological effects of coronavirus disease 2019 (COVID-19) have not been clarified. Our aim is to evaluate the available evidence regarding possible andrological consequences of COVID-19 either on seminal or hormonal parameters. The safety of the COVID-19 vaccines in terms of sperm quality was also investigated.

METHODS

All prospective and retrospective observational studies reporting information on severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) mRNA semen and male genitalia tract detection (n = 19), as well as those reporting data on semen analysis (n = 5) and hormonal parameters (n = 11) in infected/recovered patients without any arbitrary restriction were included.

RESULTS

Out of 204 retrieved articles, 35 were considered, including 2092 patients and 1138 controls with a mean age of 44.1 ± 12.6 years, and mean follow-up 24.3 ± 18.9 days. SARS-CoV-2 mRNA can be localized in male genitalia tracts during the acute phase of the disease. COVID-19 can result in short-term impaired sperm and T production. Available data cannot clarify long-term andrological effects. Low T observed in the acute phase of the disease is associated with an increased risk of being admitted to the Intensive Care Unit or death. The two available studies showed that the use of mRNA COVID-19 vaccines does not affect sperm quality.

CONCLUSIONS

The results of our analysis clearly suggest that each patient recovering from COVID-19 should be monitored to rule out sperm and T abnormalities. The specific contribution of reduced T levels during the acute phase of the infection needs to be better clarified.

P-083 The incidence of sperm DNA damage in men with chronic reproductive health issues

Study question

What is the incidence of sperm DNA damage in men attending tertiary (urological) healthcare with long histories of infertility?

Summary answer

The majority of these men (95%), all with normal semen analyses had high levels of sperm DNA damage.

What is known already

Conventional semen analysis assesses sperm concentration, motility, and morphology but with a high degree of biological variability. Around 25% of men are given a diagnosis of unexplained infertility by normal semen analysis. The World Health Organisation (WHO) stated in 2021 that ‘clinically there is a growing awareness that chromosomal anomalies and gene mutations underlie a diverse spectrum of male infertility,’ so now recommends that sperm DNA is determined as an extended analysis. Sperm DNA damage occurs more often in infertile men and DNA damage is associated with recurrent pregnancy loss and decreased live birth rates following fertility treatment.

Study design, size, duration

A retrospective study of men attending a tertiary centre with productive failure had been offered a standard semen analysis and sperm DNA fragmentation using SpermComet technology.

Participants/materials, setting, methods

Results from 148 men tested between April 2017 and September 2021 were recruited from a tertiary urological database in the UK. Alongside a semen analysis, they also had a sperm DNA fragmentation test.

Sperm DNA quality for the participants was assessed and reported as average, low and high DNA damage as a percentage compared with clinical thresholds used by Examen from their sperm data bank of 74 fertile sperm donors with recently achieved clinical pregnancies.

Main results and the role of chance

The average comet score was 37.8% +/-0.5, low comet score was 35.3% +/- 1.5 and high comet score was 20.2% +/-1.2. These values were all significantly outside ( p &lt; 0.001, Mann Whitney test)) fertile parameters.

95% of these men presenting for infertility investigations had a significantly raised DNA damage across their semen sample with low proportions of healthy sperm and high levels of sperm with genomic damage.

Limitations, reasons for caution

Retrospective design, small sample size, lack of randomisation and low power analysis.

Wider implications of the findings

Sperm DNA damage was found in most of these men who, over years of investigation hadn't been offered tests other than semen analysis or therapy to improve their sperm quality. Thus, this tool could be a useful adjunct to semen analysis to guide the men to reproductive health.

O-252 Next generation sequencing analysis of the seminal microbiome in male partners of women with idiopathic recurrent pregnancy loss: results of a prospective cohort study

Study question

Is there an association between the semen microbiome, seminal reactive oxygen species (ROS) and DNA fragmentation in men with recurrent pregnancy loss (RPL)?

Summary answer

This pilot study outlines the subtle role that microbiota play in influencing ROS and sperm DNA damage for male partners of women with RPL

What is known already

RPL is defined as the loss of two or more consecutive pregnancies. This devastating condition impacts approximately 1% of couples. Paternal causes are not routinely screened for and an underlying cause is not found in up to 50% of cases. Recent studies have reported an association between elevated seminal ROS and sperm DNA fragmentation in the male partner, and RPL. We hypothesised that seminal microbiota contribute to increased ROS and sperm DNA damage. To test this, we investigated the relationship between seminal bacterial composition and ROS levels in men with proven fertility versus men with a history of RPL.

Study design, size, duration

We conducted a prospective, case-control study and recruited participants between November 2018 and March 2020 at Imperial College Healthcare NHS Trust. A total of 109 men participated in the study; 46 men with RPL and 63 men with proven fertility and no history of RPL. Each participant attended for a single study visit which consisted of a full medical history, assessment of testicular volume, height, weight, blood samples and production of a semen sample.

Participants/materials, setting, methods

Routine semen analysis (WHO) and endocrine and lipid profiles were performed for all patients. Semen ROS and DNA fragmentation were performed (luminol and TUNEL methodologies, respectively). ROS were classified as high (&gt;3.77 RLU/s) or low (&lt;3.77 RLU/s). Metataxonomic profiling of samples was performed using Illumina Miseq-based sequencing of the V1-V2 hypervariable regions of bacterial 16S rRNA gene amplicons. Multivariate and univariate modelling was performed to explore associations between metataxonomic profiles, ROS levels and clinical metadata.

Main results and the role of chance

Men with RPL had higher mean semen volume (p = 0.02) and increased prevalence of high ROS (p = 0.02, Fisher's exact) compared with controls; but other clinical characteristics were similar between groups. A total of 3,700,136 high quality sequence reads were generated for the dataset with an average of 33,946 reads/sample. Hierarchical clustering of bacterial genera relative abundances identified 4 distinct microbial signatures characterised by high relative abundance of 1. Streptococcus, 2. Lactobacillus and Gardnerella, 3. polymicrobial (including Prevotella), and 4. Corynebacterium and Finegoldia. Prevalences of these groups were similar in control and RPL groups (p = 0.11). Additionally, no association between the bacterial genera groups and elevated ROS, DNA fragmentation, or clinical factors such as age, ethnicity, or semen volume were observed (chi-square tests). At species taxonomy level relative abundance of L. crispatus was higher in controls compared to RPL, but did not withstand false discovery rate correction for multiple testing (p = 0.006, q = 0.67). Higher relative abundance of Microbacterium was detected in semen samples with high DNA fragmentation (p = 8.7E-4, q = 0.08). This relationship was even stronger within the RPL cohort (p = 2.8E-5, q = 0.002). No significant enrichment of specific taxa was observed between high or low ROS samples however, low ROS was associated with Corynebacterium relative abundance &gt;20%.

Limitations, reasons for caution

More patients are required to enhance statistical power. Duplicate sample collection may establish the robustness of seminal compositions observed. Time since last sexual intercourse samples may affect the analysis. Concomitant analysis of the vaginal microbiome of female partners may improve our understanding of how partners may affect each other’s fertility.

Wider implications of the findings

Our data suggests interactions between microbiota composition, ROS and sperm DNA damage which may be implicated in the pathogenesis of recurrent miscarriage. Further studies are needed to determine if seminal microbiota play causal roles in RPL, and whether interventions modifying the seminal microbiome may modify pregnancy outcomes in affected couples

Practical consensus recommendations regarding the management of HER2 neu positive metastatic breast cancer

Metastatic breast cancer (MBC) is cancer that has spread from the breast to another part of the body or has come back in another distant location. Treatment options for MBC depend on several factors, including where the cancer has spread, the patient's overall health, and the levels of hormone receptors and HER2 in the tumour. Over-expression of HER2 is generally considered to be a negative prognostic feature because it accompanies an increase in breast cancer mortality. However, the development of agents that specifically target HER2 has improved the management of patients with these tumours.^{[7],[8],[9],[10]} This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of these agents and the management of HER2 positive MBC for the benefit of community oncologists.

Practical consensus recommendations on management of HR + ve early breast cancer with specific reference to genomic profiling

Breast cancer is a heterogeneous disease and patients are managed clinically based on ER, PR, HER2 expression, and key risk factors. The use of gene expression assays for early stage disease is already common practice. These tests have found a place in risk stratifying the heterogeneous group of stage I–II breast cancers for recurrence, for predicting chemotherapy response, and for predicting breast cancer-related mortality. Most guidelines for hormone receptor (HR)–positive early breast cancer recommend addition of adjuvant chemotherapy for most women, leading to overtreatment, which causes considerable morbidity and cost. Expert oncologist discussed about strategies of gene expression assays and aid in chemotherapy recommendations for treatment of HR + ve EBC and the expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Endometriosis of the appendix presenting as acute appendicitis with unusual appearance

INTRODUCTION

Endometriosis of the appendix is an uncommon mimicker of acute appendicitis which makes for a diagnostic dilemma.

PRESENTATION OF CASE

We present a rare case of a menstruating woman presenting with classic symptoms of appendicitis, without the characteristic inflammatory changes seen on laparoscopy consistent with appendicitis. Instead, the appendix appeared unusually contracted on itself. Pathologic review of the appendix revealed microscopic findings of endometriosis.

DISCUSSION

We theorize the growth and shedding of the endometrial tissue during menstruation caused compression of the neural plexi in the wall of the appendix leading to the presentation mimicking acute appendicitis.

CONCLUSION

Given the potential for endometrial appendicitis, we propose appendectomy in reproductive age female patients with right lower quadrant pain, regardless of appendix appearance on laparoscopy.

Penile lymphoedema: approach to investigation and management

BACKGROUND

Penile lymphoedema (with and without cellulitis) is a rare, often chronic, clinically heterogeneous entity with an uncertain pathogenesis and an important differential diagnosis. It creates significant physical and psychosexual morbidity, and presents considerable therapeutic challenges. The existing literature is limited.

AIM

To describe and share our updated cumulative experience of a cohort of patients with penile lymphoedema.

METHODS

This was a retrospective review of the case records of patients with chronic penile lymphoedema seen in two dedicated male genital dermatology clinics between January 2011 and July 2016.

RESULTS

In total, 41 cases were identified. Over a third had Crohn disease (CD) (which was occult in one-third of these), and over a third had serological evidence of streptococcal infection. All patients responded to systemic antibiotics and specialized urological surgery circumcision and excision).

CONCLUSIONS

Penile lymphoedema should be investigated to exclude underlying pathology especially CD and streptococcal infection. Treatment with antibiotics should be considered early and long term to try to preserve the foreskin: most patients are uncircumcised. Some patients may benefit from a course or courses of oral steroids. The development of gross dysfunction of the prepuce usually dictates circumcision and excision of lymphoedematous tissue once the situation is medically stabilized.

Practical consensus recommendation on when to do BRCA testing

BRCA-mutation associated breast cancer and to future cancer risks and sensitivity to systemic therapies. Now that rapid genetic testing for BRCA1 and BRCA2 mutations is available, BRCA mutation status can be considered when making treatment and prevention decisions for BRCA testing, BRCA mutation carriers with breast cancer. Expert group used data from published literature, practical experience, and opinion of a large group of academic oncologists, to arrive at practical consensus recommendations for use by the community oncologists.

The Role and Timing of Treatment Strategies During Two-Stage Revision for Periprosthetic Joint Infections

INTRODUCTION

Prosthetic joint infection continues to be a source of significant morbidity to patients and an economic burden to society as a whole. Two-stage revision is the current gold standard for treatment of periprosthetic joint infection in North America. Despite this, much discussion persists about treatment strategies surrounding the interim of the two-stage revision and treatment beyond reimplantation. The aim of this review is to answer some of these questions, specifically: are C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) helpful prior to reimplantation, is aspiration helpful, what is the role and timing for systemic antibiotics, and is there a role for oral suppression following second-stage reimplantation?

METHODS

A literature review was completed in an attempt to address unanswered questions associated with two-stage reimplantation. Investigators' recommendations and current practices are described.

RESULTS

ESR and CRP are less reliable in the interim of a two-stage revision than for diagnosis of infection in a primary total joint arthroplasty. There is inconclusive evidence regarding the utility of joint aspiration in two-stage revisions. Additionally, no evidence has been developed for length of IV antibiotic treatment after second-stage reimplantation, and in a few studies, oral antibiotic suppression has shown some benefit in reducing reinfection rates.

CONCLUSION

The question of optimum treatment strategies has yet to be answered: attempts are underway to obtain suitable data with multi-center studies and large patient populations. Periprosthetic joint infection is a serious and life altering complication and with continued research we can further clarify treatment strategies.

Self injection of foreign materials into the penis

Injection of the subcutaneous tissues of the penis for enlargement of penile girth has been practised for many years by laypeople and medical practitioners alike. However, with recognition of the complications, the practice has died out. We report a series of five patients who presented having injected foreign materials into the subcutaneous tissues of their penises, including paraffin and mineral oils. Our patients had a variable time course of presentation ranging from 1 day following injection to over 26 years. Self-injection of the subcutaneous tissues of the penis is an unusual presentation for a penile mass but should be considered as a differential diagnosis in patients with a long latent period to presentation or with characteristic magnetic resonance imaging and histological appearances.

Minimal Invasive Management of Lymph Nodes

Penile cancer is a rare genitourinary malignancy. Lymph node involvement is the single most important factor determining survival in these patients, and those patients with occult disease are difficult to identify on conventional cross-sectional imaging. Until recently, lymph node sampling (eg, lymphadenectomy) has been the diagnostic modality of choice in the detection of micrometastasis. More recently, several novel molecular and minimally invasive diagnostic techniques have been developed, which have been demonstrated to decrease the false-negative and -positive results of conventional imaging and lymphadenectomy. This article focuses on the minimally invasive management of lymph nodes in men with penile cancer.

Schwannoma of the ansa cervicalis

Schwannomas are rare neoplasms that originate from Schwann cells. We present a case report of schwannoma of the ansa cervicalis in a patient where preoperative imaging suggested thyroid pathology. A 25-year-old man presented to the otolaryngology department with a one-year history of an asymptomatic, anterior triangle neck swelling. Imaging and FNA suggested a cystic lesion of the thyroid. However, intraoperatively, the lesion was found between the right sternohyoid and thyrohoid and histology showed findings consistent with a diagnosis of schwannoma, determined to originate from the ansa cervicalis based on its anatomical position. Schwannoma of the ansa cervicalis is extremely rare and there have only been four reported cases in the literature. Schwannomas are often misdiagnosed and confused for other lesions. In our case report we add to the sparse literature on this pathology and highlight common pitfalls in diagnosis and discuss the principles of management of this rare condition.

The Management of Stuttering Priapism within a Specialist Unit—A 25-Year Experience

Introduction:

Stuttering priapism is a rare condition characterised by recurrent prolonged erections. The condition is common in patients with sickle cell disease although a significant proportion suffer from idiopathic stuttering priapism. The management of this condition is mainly through anecdotal reports.

Methods:

We have retrospectively reviewed 60 patients with this condition in a single centre over a 25-year period. Risk factors were identified and the outcomes of both pharmacological therapies and surgical interventions were recorded.

Results:

Erections were characteristically nocturnal and painful in nature and lasted up to 72h in some patients. Analysis of the outcomes of both medical and surgical interventions has shown that the use of hormone analogues such as cyproterone acetate is the most efficacious treatment option as it allows a successful control of their erections without a significant loss of libido in 86% of patients. The most successful surgical option was the insertion of a penile prosthesis.

Conclusion:

Due to the rarity of this condition, the management is variable and based on anecdotal evidence. This study has reported our experience of the most efficacious treatment options for this condition. We also discuss the potential therapeutic role of PDE-5 inhibitors in this condition.

Stuttering priapism--a review of the therapeutic options

INTRODUCTION

Priapism is a urological emergency which is commonly classified into low-flow and high-flow priapism. Immediate intervention is required for low-flow cases as the development of ischaemia ultimately leads to long-term erectile dysfunction. Stuttering or recurrent priapism is less well understood. This subtype is characterised by short-lived painful erections and is commonly encountered in patients with sickle cell disease.

METHODS

A systematic review of the treatment options available for stuttering priapism is presented combined with our own experience in managing this condition over a period of 25 years.

RESULTS

Although numerous medical treatment options have been reported, the majority are through small trials or anecdotal reports.

CONCLUSIONS

Stuttering priapism is a condition which is still not well understood and there is no standardised algorithm for the management of this condition. A multicentre randomised trial is required to evaluate the treatment options.

Phosphodiesterase 5 inhibitors in the treatment of premature ejaculation

To date, there is no FDA-approved therapy for premature ejaculation (PE). Recently, phosphodiesterase 5 inhibitors (PDE5-Is) have been demonstrated to have encouraging results in the treatment of PE by a few studies. The aim of this review was to assess the updated manuscripts and thereafter present the practical recommendations and possible mechanisms concerning PDE5-Is for treating PE. Using MEDLINE, we searched and assessed the peer manuscripts published from 1 January 1996 to 1 September 2005 about PDE5-Is for treating PE. The results show that the number of patients in all the reports is very few and most of the studies do not employ double-blinded and placebo-controlled tests, though they are prospective and randomized. Therefore, the results and conclusions might be biased. PDE5-Is are suggested to be used in PE with old age or associated with erectile dysfunction (ED), or to be employed alone or in combination with selective-serotonin reuptake inhibitors (SSRIs) when SSRIs fail to treat PE; behavioural therapy is proposed to be used for preventing the recurrence of PE following withdrawal of PDE5-Is. In addition, for the PE patient with a definite aetiological cause, the aetiology should be cured first, if PE still exists, followed by PDE-Is prescription. Possible mechanisms that are involved include relaxing the smooth muscles of vas deferens, seminal vesicle, prostate and urethra; decreasing the central sympathetic output; inducing peripheral analgesia; prolonging the duration of erection; and increasing confidence, the perception of ejaculatory control, overall sexual satisfaction, and decreasing the post-orgasmic refractory time to achieve a second erection after ejaculation. Well-designed multicentre studies are urgently warranted to further elucidate the efficacies and safety as well as mechanisms of PDE5-Is in the treatment of PE.

Adjuvant trastuzumab (T) therapy in HER2+ breast cancer after ASCO 2005: Patients’ attitudes and immediate economic burden

10565

Background: Data from 3 large randomized trials documenting the efficacy of T in the adjuvant setting were reported at ASCO 2005, and subsequently published in NEJM 2005; 353: (16) pp 1659–72 and 1673–1684 . We decided to offer T, and attempted to assess patients’ characteristics that influence its acceptance, in a subgroup of HER2 + patients that had already completed adjuvant chemotherapy at our institution within 12 months prior to these reported results. Methods: Using Electronic Medical Records (OpTx, Canada), we identified HER2+ breast cancer patients who had completed adjuvant therapy within the prior 12 months and administered an informational synopsis about the study results. They then completed a questionnaire, including their demographic information, that established their understanding of the data and documented their decision to receive or to not receive adjuvant T as an afterthought. Results: We identified 1442 breast cancer patients in Optx that were seen at UTCI for initial or follow up visits between May 2004 and May 2005. Those with 3 or fewer visits within the last year and those who received no chemotherapy (n = 770) were excluded. Of the remaining 672 patients, only 104 (15%) had documented HER2+ disease. Fourteen HER2+ patients had metastatic disease, while 84 patients, though HER2+, had either completed adjuvant chemotherapy greater than 12 months prior or were currently receiving adjuvant therapy or T, and/or had other reasons to not be suitable for T. Six patients qualified for this study; 5 decided to receive adjuvant T and 1 chose not to because she perceived the additional benefit to be minimal. Conclusions: While our sample size was too small in the end to draw conclusions about patients’ attitudes towards new data on adjuvant T, we were struck by the small number of patients who could be offered T as an afterthought despite our large patient volume. The magnitude of the perceived economic burden and its imminence after the release of these data may have been overestimated.
