RESUMO

BACKGROUND: Suicide prevention is an important public health concern, and primary care physicians (PCPs) often serve as the first point of contact for individuals at risk. Few interventions in the primary care setting have been linked to reduced suicide attempt (SA) rates. The Continuity of Care (COC) protocol was developed to improve the primary care treatment of high-risk suicidal patients. OBJECTIVES: This study examined PCPs' awareness of the COC protocol, its perceived effectiveness, and PCPs' attitudes towards post-SA-discharge visits. METHODS: A survey was administered to 64 PCPs who had a recent office visit with a patient who had attempted suicide. Data were collected between May and July 2021 and analyzed anonymously. RESULTS: Thirty of the 64 PCPs answered the questionnaires, giving a response rate of 47%. Most were unaware of the COC protocol. Seventeen physicians (57%) felt that the visit strengthened their physician-patient relationship, and while nearly half of the physicians (47%, n = 14) agreed they had the knowledge and tools to manage a post-SA-discharge visit, 43% of them (n = 13) preferred that the visit would have been handled by a mental health professional rather than a PCP. Analysis of open-ended questions uncovered three themes: knowledge gap, system limitation, and the PCP's role in maintaining the COC. CONCLUSION: The findings of this study highlighted the important role PCPs can play to prevent future SAs, as well as exposed gaps in the knowledge and system constraints that impede them from carrying out this role as effectively as possible.


Primary care physicians (PCPs) are often the first point of contact for individuals at risk of suicide and can play a critical role in suicide prevention. Our study examined the perceptions and attitudes of PCPs towards the Continuity of Care (COC) protocol, an intervention designed to improve primary care treatment of high-risk suicidal patients. The study surveyed 64 PCPs who had recently seen a patient who had attempted suicide, and 47% of them responded to the survey. While the study revealed areas for improvement, it also highlighted the perceived importance of the physician­patient relationship in preventing future suicide attempts. The study also revealed that many PCPs felt they had the knowledge and tools to manage a post-attempt discharge visit and that the visit strengthened their physician­patient relationship. However, the study also identified gaps in knowledge and system limitations that can impede PCPs from carrying out their role effectively. It is important to continue to improve training and support for PCPs in order to better equip them to handle high-risk suicidal patients and prevent future suicide attempts.

RESUMO

RESEARCH QUESTION: Does Pfizer's coronavirus disease 2019 (COVID-19) vaccination detrimentally affect semen analysis parameters? DESIGN: A prospective cohort study was conducted at a single large tertiary centre in Israel between February and March of 2021. Semen samples from 75 fertile men were analysed 1-2 months following their second dose of Pfizer's COVID-19 vaccine. The semen parameters were compared with the World Health Organization (WHO) reference ranges. The primary outcome was the percentage of abnormal semen parameters in those who were vaccinated, i.e. the rates of oligozoospermia, reduced percentage of motile spermatozoa and abnormal sperm morphology. RESULTS: The interval from the time of the second vaccination to the date of participation was on average 37 days, with most subjects describing either mild or no side effects after the first or second dose. The mean sperm concentration was 63.2 ± 33.6 â€¯×  106/ml, with only a single participant (1.3%) with a sperm count of 12.5 â€¯×  106/ml, considered by the WHO to be oligozoospermic. The mean sperm motility percentage was 64.5 ± 16.7%, with only a single man (1.3%) displaying reduced motility. No notable morphological abnormalities were observed. This constituted a lower percentage of abnormal semen parameters compared with the 5% rates reported in fertile men by the WHO. CONCLUSIONS: The semen parameters following COVID-19 vaccination were predominantly within the normal reference ranges as set by the WHO and do not reflect any causative detrimental effect from COVID-19 vaccination. The results strengthen the notion that the Pfizer's severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine is safe and should be recommended to men wishing to conceive.

RESUMO

RESEARCH QUESTION: What are the cumulative clinical pregnancy rates (CPR) and live births rates (LBR) in intracytoplasmic sperm injection (ICSI) cycles using testicular motile compared with immotile spermatozoa, obtained from testicular sperm aspiration (TESA) or extraction (TESE)? DESIGN: A retrospective analysis of ICSI cycles using TESA or TESE over a period of 7 years. Cycles were divided into two groups according to the motility of the retrieved spermatozoa: Group A consisted of couples with motile spermatozoa; Group B of couples with immotile spermatozoa. Group B was subdivided into two groups: B1 consisted of couples with motile spermatozoa and B2 with immotile spermatozoa after the addition of pentoxifylline. RESULTS: No differences in CPR and LBR per transfer was found between the study groups after fresh embryo transfer. No pregnancies were achieved by vitrified-warmed embryo transfer in group B2. Fertilization rates decreased when using immotile spermatozoa (64.4%, 56%, 37.9%, for groups A, B1 and B2, respectively, P < 0.001). Top-quality embryo rates were higher in groups A and B1 compared with B2 (40.7% and 40.1% versus 19.1%, respectively, P = 0.015). Cumulative CPR (53%, 41.7%, 13.6% for groups A, B1 and B2, respectively, P = 0.005) and LBR (42.4%, 30%, 13.6% for groups A, B1 and B2, respectively P = 0.03) per oocyte retrieval was significantly higher when using motile spermatozoa compared with motile or immotile spermatozoa after adding pentoxifylline. CONCLUSIONS: Although fertilization, top-quality embryo rates, cumulative CPR and LBR decreased when using immotile spermatozoa, ICSI is still valid; therefore, it should be considered and offered to couples before embarking on a donor sperm insemination cycle, or cryopreserving oocytes for future additional testicular sperm retrieval.

RESUMO

BACKGROUND: Little is known about oncologic outcomes following robot-assisted-radical-prostatectomy (RALP) for clinical T3 (cT3) prostate cancer. OBJECTIVES: To investigate oncologic outcomes of patients with cT3 prostate cancer treated by RALP. METHODS: Medical records of patients who underwent RALP from 2010 to 2018 were retrieved. cT3 cases were reviewed. Demographic and pre/postoperative pathology data were analyzed. Patients were followed in 3-6 month intervals with repeat PSA analyses. Adjuvant/salvage treatments were monitored. Biochemical recurrence (BCR) meant PSA levels of ≥ 0.2 ng/ml. RESULTS: Seventy-nine patients met inclusion criteria. Median age at surgery was 64 years. Preoperative PSA level was 7.14 ng/dl, median prostate weight was 54 grams, and 23 cases (29.1%) were down-staged to pathological stage T2. Positive surgical margin rate was 42%. Five patients were lost to follow-up. Median follow-up time for the remaining 74 patients was 24 months. Postoperative relapse in PSA levels occurred in 31 patients (42%), and BCR in 28 (38%). Median time to BCR was 9 months. The overall 5-year BCR-free survival rate was 61%. Predicting factors for BCR were age (hazard-ratio [HR] 0.85, 95% confidence interval [95%CI] 0.74-0.97, P = 0.017) and prostate weight (HR 1.04, 95%CI 1.01-1.08, P = 0.021). Twenty-six patients (35%) received adjuvant/salvage treatments. Three patients died from metastatic prostate cancer 31, 52, and 78 months post-surgery. Another patient died 6 months post-surgery of unknown reasons. The 5-year cancer-specific survival rate was 92. CONCLUSIONS: RALP is an oncologic effective procedure for cT3 prostate cancer. Adjuvant/salvage treatment is needed to achieve optimal disease-control.

RESUMO

We sought to compare ICSI outcomes of cycle using fresh versus thawed TESE spermatozoa obtained during the previous fresh TESE. All consecutive couples undergoing ICSI cycles using fresh TESE spermatozoa, followed by ICSI cycle using cryopreserved sperm remaining from the previous fresh TESE procedure were included. Ovarian stimulation (OS)/laboratory variables and cycle outcome were assessed and compared between those utilising fresh versus thawed TESE spermatozoa. Seventy-five couples were evaluated, with no in-between groups differences in OS nor embryological variables. While implantation and LBR per embryo transfer were nonsignificantly higher in the frozen as compared to the fresh TESE, there was a trend towards higher LBRs per patient in the frozen TESE group. The cumulative miscarriage rate (4% versus 14.7%, p < .022 respectively) was significantly lower and the cumulative LBR (34.7% versus 16%, p < .007 respectively) was significantly higher using frozen TESE spermatozoa. Moreover, significantly higher proportion of frozen TESE sperm samples used pentoxifylline to enhance sperm motility. In conclusion, the results of ICSI cycles using frozen TESE spermatozoa are as good, or even better than using fresh TESE spermatozoa. Further studies are required to explore the factors responsible for the improved ICSI outcome, while using frozen versus fresh TESE sperm samples.

RESUMO

INTRODUCTION: We aimed to compare systematic biopsies (SBs) of in-bore magnetic resonance-guided prostate biopsy (MRGpB) with those performed under transrectal ultrasound (TRUS) guidance in the clinical setting. METHODS: Data on all 161 consecutive patients undergoing prostate biopsy at our institution between November 2017 and July 2019 were retrospectively collected. The patients were referred to biopsy due to elevated prostate-specific antigen (PSA) and/or abnormal digital rectal examination (DRE) and/or at least one Prostate Imaging Reporting and Data System (PI-RADS) lesion score of ≥3 on multiparametric magnetic resonance imaging (mpMRI). We included patients with PSA levels ≤20 ng/ml and those with 8-12 core biopsies. Histology results of SBs performed by in-bore MRGpB were compared to TRUS SBs. Chi-squared, Fischer's exact, and multivariate Pearson regression tests were used for statistical analysis (SPSS, IBM Corporation). RESULTS: In total, 128 patients were eligible for analysis. Their median age was 68 years (interquartile range [IQR] 61.5-72), mean prostate size 55±29 cc, and mean PSA and PSA density levels 7.6±3.5 ng/ml and 0.18±0.13 ng/ml/cc, respectively. Thirty-five patients (27.3%) had suspicious DRE findings. Both biopsy groups were similar for these parameters. Thirty-eight (62.3%) MRGpB patients had a previous biopsy vs. five (7.1%) TRUS-SB patients (p<0.0001). The number of patients diagnosed with clinically significant and non-significant disease was similar for both groups. High-risk disease was more prevalent in the TRUS-SB group (22.4% vs. 4.9%, p<0.01). CONCLUSIONS: Our data suggest that in-bore MRGpB is no better than TRUS for guiding SBs for the detection of clinically significant prostate cancer.

RESUMO

The prostate specific antigen (PSA), a serine protease with chymotrypsin-like activity, is predominantly expressed in the prostate and is considered as the most common marker in use to identify and follow the progress of prostate cancer. In addition, it is also now accepted as a marker for detecting semen in criminal cases. Here, we describe the design, synthesis, and evaluation of the first chemiluminescence probe for detection of PSA enzymatic activity. The probe activation mechanism is based on a catalytic cleavage of a specific peptidyl substrate, followed by a release of a phenoxy-dioxetane luminophore, that then undergoes efficient chemiexcitation to emit a green photon. The probe exhibits a significant turn-on response upon reaction with PSA and produces strong light emission signal with an extremely high signal-to-noise ratio. Comparison of the chemiluminescence probe with an analogous fluorescence probe showed superior detection capability in terms of response time and sensitivity. In addition, the probe was able to efficiently detect and image human semen traces on fabric, even after 3 days from sample preparation. The advantageous sensitivity and simplicity of a chemiluminescence assay to detect seminal fluid was effectively demonstrated by on-site measurements using a small portable luminometer. It is expected that the new chemiluminescence probe would be broadly useful for numerous applications in which PSA detection or imaging is required.

RESUMO

We aim to evaluate our experience, comparing intracytoplasmic sperm injection (ICSI) outcomes of cycle using fresh versus thawed electroejaculated spermatozoa. All consecutive couples undergoing ICSI cycles using electroejaculated spermatozoa, during a 16-year period, were evaluated. Embryological/laboratory variables of the ICSI cycles were assessed and compared between those utilising fresh (fresh group) versus thawed (thawed group) electroejaculated spermatozoa. Fifty-seven couples were evaluated, 30 used a fresh electroejaculated spermatozoa in 55 ICSI cycles, while 27 used a thawed sperm sample in 41 ICSI cycles. There were no in-between group differences in the mean numbers of oocytes retrieved per oocyte retrieval nor the percentage of MII oocytes. The fresh group demonstrated significantly higher fertilisation (71.5% vs. 64.1%, respectively, p < .05), top-quality embryos (66.5% vs. 54.9%, respectively, p < .02), clinical pregnancy per transfer (41.3% and 21.2%, respectively, p < .05) and cumulative clinical pregnancy (58.2% vs. 26.8%, respectively, p < .001) rates, as compared to the thawed group. Independent of the source of spermatozoa used, no pregnancy was achieved following ICSI utilising immotile spermatozoa. In conclusion, ICSI cycles using ejaculated spermatozoa of patients suffering from neurologic or psychogenic anejaculation are reassuring. The use of fresh ejaculated spermatozoa retrieved on the day of the female spouse oocyte retrieval might improve outcome. Whenever a thawed electroejaculated spermatozoa yield no motile spermatozoa, emergency electroejaculation is mandatory.

RESUMO

Advanced prostate cancer remains incurable and is the second leading cause of mortality in men. Immunotherapy based on the adoptive transfer of tumor-infiltrating lymphocytes (TIL) has demonstrated promising clinical results in patients with metastatic melanoma and lately also in other solid tumors. However, the ability to obtain TIL from patients with prostate cancer, considered poorly immunogenic, remains unknown. In this study, we investigate the feasibility of isolating and expanding TIL from primary prostate tumors. We collected tumor specimens from eight patients with diagnosed prostate adenocarcinoma undergoing radical prostatectomy and were able to successfully expand multiple autologous TIL cultures from all patients. Twenty-eight prostate-TIL cultures were further expanded using a standard rapid expansion procedure under Good Manufacturing Practice conditions. TIL cultures were phenotypically characterized for T cell subset composition, differentiation status and co-inhibitory/stimulatory markers such as PD-1, TIM-3, LAG-3, and CD28 and were found to have in general similarity to TIL obtained from patients with melanoma and lung carcinoma previously treated at our center. All analyzed TIL cultures were functional as determined by the capability to produce high level of IFNγ upon stimuli. Most importantly, co-culture assays of prostate-TIL with autologous tumors demonstrated anti-tumor reactivity. In conclusion, these findings demonstrate that functional and anti-tumor reactive TIL can be obtained, despite the immunosuppressive microenvironment of the cancer, thus this study supports the development of TIL therapy for prostate cancer patients.

RESUMO

PURPOSE: Focal therapy in low-risk prostate cancer may provide the best balance between cancer control and quality of life preservation. As a minimally invasive approach performed under TRUS guidance, brachytherapy is an appealing framework for focal therapy. However, the contrast in TRUS images is generally insufficient to distinguish the target lesion from normal prostate tissue. MRI usually offers a much better contrast between the lesion and surrounding tissues. Registration between TRUS and MRI may therefore significantly improve lesion targeting capability in focal prostate brachytherapy. In this paper, we present a deformable registration framework for the accurate fusion of TRUS and MRI prostate volumes under large deformations arising from dissimilarities in diameter, shape and orientation between endorectal coils and TRUS probes. METHODS: Following pose correction by a RANSAC implementation of the ICP algorithm, TRUS and MRI Prostate contour points are represented by a 3D extension of the shape-context descriptor and matched by the Hungarian algorithm. Eventually, a smooth free-form warping is computed by fitting a 3D B-spline mesh to the set of matched points. RESULTS: Quantitative validation of the registration accuracy is provided on a retrospective set of ten real cases, using as landmarks either brachytherapy seeds (six cases) or external beam radiotherapy fiducials (four cases) implanted and visible in both modalities. The average registration error between the landmarks was 2.49 and 3.20 mm, for the brachytherapy and external beam sets, respectively, that is less than the MRI voxels' long axis length ([Formula: see text]). The overall average registration error (for brachytherapy and external beam datasets together) was 2.56 mm. CONCLUSIONS: The proposed method provides a promising framework for TRUS-MRI registration in focal prostate brachytherapy.

RESUMO

The phenomenon of suicide during military service is not unique to the Israeli military and other armies. Soldiers' age--adolescence--is a known factor contributing to suicide, in light of psychological processes of identity formation and self-definition, the stresses of military service, and above all, the availability of weapons. The stigma of seeking help deters some soldiers from getting the assistance they need when they need it most, thus contributing to the higher suicide rate. In the previous decade the IDF initiated intensive and structured preventive procedures aimed at reducing suicide rate among soldiers. The IDF's Suicide Prevention Program (SPP) was grounded in professional knowledge and backed by military policy changes, both critical to the implementation and change processes. The SPP includes thorough psycho-education and guidance, supervision, greater accessibility of mental health officers, and lower accessibility of nonessential weapons. The SPP has succeeded in reducing the suicide rate by almost 50 %. The aim of this article is to review the background of the design of the IDF's SPP and its major components, leading to the current success.

RESUMO

OBJECTIVES: To compare the sexual function of women with and without vaginal penetration difficulties (VPDs) and relate it to the sexual function of their male partners. METHODS: All consenting women attending a sexual medicine centre during 2005-2007 completed the Female Sexual Function Index (FSFI) and answered questions about five VPDs (placement of a tampon, gynaecological examination, insertion of her or her partner's finger, and penile-vaginal intercourse). Male partners filled the International Index of Erectile Function (IIEF). RESULTS: Full data were available for 223 women, and 118 male partners. Male partners of women with VPDs (n = 53) had lower sexual desire (p = 0.0225). The number of VPDs in the women concerned negatively correlated with their partners' desire (r = - 0.18339, p = 0.0468) and erectile function (r = - 0.19848, p = 0.0312). All women with at least one VPD (n = 109) reported significantly more sexual pain (p < 0.0001) and had worse sexual function scores (p = 0.014) than women with no VPDs (n = 114). Women with VPDs other than penile-vaginal penetration had worse orgasmic functioning (p = 0.0119). CONCLUSIONS: The women's VPDs are correlated with worse sexual functioning for them and for their male partners. The five VPDs are a practical and useful tool for identifying impaired sexual functioning.

RESUMO

OBJECTIVES: To examine the rate of prostate cancer in a cohort of schizophrenia in-patients in the PSA-era as compared to expected rates. There is conflicting evidence on the relative risk of prostate cancer in men with schizophrenia. METHODS: the study sample was comprised of schizophrenia patients who had been admitted to a tertiary care mental health center between 1990 and 2011. The data for the sample was cross-referenced with the National Cancer Registry. Analyses of Standardized Incidence Rates (SIR) for prostate cancer and for lung cancer (representing an organ system not sensitive to sex hormones) were performed. RESULTS: Of 4,326 schizophrenia patients included in the present study, 181 (4.2%) were diagnosed with cancer at any site. Only 10 of these patients were diagnosed with prostate cancer. This reflects a reduced risk; SIR of 0.56 (95% CI 0.27-1.03). In the same cohort, 33 schizophrenia patients were diagnosed with lung cancer presenting a SIR of 1.43 (95% CI 0.98-2.01) in this sample. CONCLUSIONS: The present study suggests a reduced rate of prostate cancer in patients admitted for schizophrenia. There are several possible explanations for this finding including chronic state of hyperprolactinemia induced by antipsychotic drugs.

RESUMO

BACKGROUND: The increasing prevalence of cancer survivors who are infertile due to gonadal failure highlights the importance of fertility preservation prior to gonadotoxic treatments. Adolescent cancer patients may not be mature enough to produce sperm by masturbation, leading to the use of alternative methods for obtaining sperm for cryopreservation. The aim of the current study was to evaluate the safety and efficacy of electroejaculation (EEJ) for cryopreservation among adolescent cancer patients. PROCEDURE: This retrospective cohort study included 45 adolescent (12-18 years old) cancer patients who underwent EEJ during 2002-2012 in an academic tertiary referral fertility center. Sperm cryopreservation, ejaculate parameters, and procedure complications were evaluated. RESULTS: EEJ was performed without documented complications. Sperm was successfully obtained in 30 (66.7%) patients. Retrieval failures included ejaculates without sperm in 8 patients (17.8%) and no ejaculate in 7 patients (15.5%). Cryopreserved ejaculates were characterized by severe asthenospermia, normal sperm concentration, and low volume. Retrieved sperm group was further divided to 19 motile sperm ejaculates with significantly higher volume, sperm concentration, and total count compared to 10 non-motile sperm patients. CONCLUSIONS: EEJ is a safe and feasible procedure for cryopreservation in adolescent cancer patients who are unable to masturbate. The wide diversity of EEJ outcome and ejaculate parameters may represent a continuum of pubertal changes in that population.

RESUMO

Eight infertile men with various degrees of oligoasthenoteratozoospermia and repeated implantation failure were selected for this study due to exceptionally high rates of sperm aneupoidy in their ejaculates. All subjects had normal physical examination, karyotype and serum FSH concentration. Prior to IVF treatment, spermatozoa was collected, processed, micromanipulated and tested for chromosomes X, Y and 18 using fluorescence in-situ hybridization. Aneupoidy rates for chromosomes X, Y and 18 were determined among sperm population selected for normal morphology using high-order magnification light microscopy. A second group of fast motile spermatozoa were collected using an intracytoplasmic sperm injection pipette from the medium-oil interface from microdroplets. The average aneuploidy rates for the three chromosomes were 7.6% (395/5182) in the sperm specimen before selection, 8.7% (116/1326) in the normal morphology selected group and 4.3% (59/1388; P<0.001) in the fast motile selected group. In conclusion, high-magnification light microscopy aimed at selection of spermatozoa with normal morphology did not affect the aneuploidy rate. On the other hand, fast motile spermatozoa harboured significantly less chromosomal abnormalities (P<0.001). Preselection of the most rapid sperm subpopulation for intracytoplasmic sperm injection may improve the qualities of the fertilizing spermatozoon.

RESUMO

Hematospermia is usually caused by nonspecific inflammation of the prostate and seminal vesicles. Transrectal ultrasound (TRUS) is a safe and inexpensive modality for evaluating patients with hematospermia. The aim of this study is to describe the findings of TRUS and its contribution to patients' management. A total of 115 consecutive patients presented with hematospermia and evaluated with TRUS between 2006 and 2012. All patients exhibited an abnormality in the TRUS examination. A 12-core TRUS-guided biopsy of the prostate was taken from 10 patients, but none of these samples were positive for tumor. In the vast majority of cases, a benign cause can be identified using TRUS. These causes usually do not require treatment.

RESUMO

OBJECTIVE: To evaluate sperm quality and fertility potential of men with psychogenic anejaculation treated by electroejaculation (EEJ) and intracytoplasmic sperm injection (ICSI). Treatment results were compared to spinal cord injured (SCI) patients treated similarly. DESIGN: Retrospective clinical study. SETTING: Academic tertiary referral fertility center. PATIENT(S): Couples with isolated psychogenic anejaculation or SCI. INTERVENTION(S): Electroejaculation and ICSI. MAIN OUTCOME MEASURE(S): Semen analysis, fertilization rate, implantation rate, pregnancy rate, delivery rate and safety of the procedure. RESULT(S): Fifteen patients diagnosed with psychogenic anejaculation underwent 40 EEJ/ICSI cycles. The semen retrieved was characterized by low motility (mean 10.7% ± 12.3%), normal volume (2.2 ± 1.9 mL) and normal count (25.1 ± 29.9 × 10(6)/mL), according to World Health Organization criteria. Results of EEJ/ICSI were compared with 22 SCI patients treated by 66 EEJ/ICSI cycles during the same period. Mean female age and the number of oocytes retrieved per cycle were similar between the groups. Similar semen parameters after EEJ were found between psychogenic and SCI patients. Fertilization rate was significantly lower in the psychogenic patients compared to SCI (47.0% and 57.0%, respectively). No significant differences were found regarding pregnancy rates (20% and 22.7%, respectively), implantation rate (10.2% and 11.6%, respectively) or delivery rates (15% and 18.2%, respectively). CONCLUSION(S): Sperm retrieved by EEJ is characterized by asthenospermia and normal count. In spite of the lower fertilization rate in psychogenic patients, combination of EEJ and ICSI gives adequate results to couples with psychogenic anejaculation similar to the results obtained for SCI patients. Current results give these couples a reasonable chance of pregnancy achievement.

RESUMO

This study defines characteristics of delayed help-seeking in men who fail phosphodiesterase-5 inhibitors (PDE5I) treatment for their post radical retropubic prostatectomy (RRP) erectile dysfunction (ED). Medical charts were reviewed retrospectively. All men were offered second line treatment with vacuum devices or intracavernous injection (ICI) and sex therapy. This study included thirty one patients. Average age at surgery was 60 years (SD = 5.3, range 46-70). Average period for second line help-seeking was 25.9 months (SD = 12.9, range 3-111). All subjects believed that surgery would not affect their sexual function. Twenty men (65%) used ICI as a second line treatment. Eleven men (35%) declined treatment, waiting for spontaneous recovery. In ICI sub-group, 5 men (25%) regained spontaneous erection within 7-10 months after initial treatment (16-19 months post-surgery). Seven men (35%) responded positively to PDE5I 3-5 months after starting ICI. Three men (15%) used vacuum device. None regained spontaneous erection. All 7 men (23%) who met sex therapist with their partner reported improved sexual life, even if ED wasn't resolved. Patients should receive comprehensive information about sexual recovery, to encourage early ED treatment after RRP and to overcome unwanted misconceptions regarding spontaneous recovery.

RESUMO

OBJECTIVE: Erectile dysfunction (ED) following radical prostatectomy is of major concern for both patients and caring physicians. We evaluated the bulbocavernosus reflex latency (BCRL) and amplitude (BCRA) following bilateral nerve-sparing radical retropubic prostatectomy (NS-RRP) to predict the response to sildenafil citrate (SC). METHODS: Patients were recruited in our ED clinic following NS-RRP. Exclusion criteria included preoperative significant ED, neurological disease, and nitrates treatment. Patients were defined as non-responders only after four consecutive unsuccessful trials of 100 mg SC. RESULTS: Twenty patients at least 3 months after surgery were included in this study. Five patients (25%) regained spontaneous erections, although insufficient for vaginal penetration. All of them had normal BCRL and normal BCRA as well as good response to 100 mg SC. Three patients (15%) lacked spontaneous erections and had prolonged BCRL with normal BCRA. This subgroup eventually regained erections using SC. Twelve patients (60%) lacked spontaneous erections and had prolonged BCRL and low BCRA. They failed SC trials and achieved erections using intra-cavernosal injections (ICI) of 10 microg PGE(1). CONCLUSIONS: Neurophysiologic evaluation consisting of BCRL and BCRA was found to be useful in the prediction of the response to SC following bilateral NS-RRP. Patients who do not regain an erection, and have abnormal BCRL and BCRA 6 months after surgery, will probably be SC non-responders and may benefit from ICI. A subset of patients with preserved BCRA and prolonged latencies has been shown to have a better chance to respond to SC.

RESUMO

PURPOSE: To report the performance of fluorescence in-situ hybridization in the setting of preimplantation genetic diagnosis in order to diagnose embryos affected by DiGeorge syndrome. DESIGN: Case report. SETTING: Academic referral center. PATIENT: A 32 year-old female affected by DiGeorge syndrome. INTERVENTION(S): History and physical examination, karyotyping, amniocentesis, preimplantation genetic diagnosis, fluorescence in-situ hybridization. MAIN OUTCOME MEASURE(S): Avoidance of pregnancy with embryo affected by DiGeorge syndrome. RESULT(S): Termination of pregnancy with an affected embryo followed by fluorescence in-situ hybridization based preimplantation genetic diagnosis and delivery of healthy offspring. CONCLUSION(S): The combination of preimplantation genetic diagnosis with fluorescence in-situ hybridization is recommended to prevent pregnancies with DiGeorge syndrome affected embryos in properly selected patients.
