EEG for good outcome prediction after cardiac arrest: a multicentre cohort study.

AIM: Assess the prognostic ability of a non-highly malignant and reactive EEG to predict good outcome after cardiac arrest (CA). METHODS: Prospective observational multicentre substudy of the "Targeted Hypothermia versus Targeted Normothermia after Out-of-hospital Cardiac Arrest Trial", also known as the TTM2-trial. Presence or absence of highly malignant EEG patterns and EEG reactivity to external stimuli were prospectively assessed and reported by the trial sites. Highly malignant patterns were defined as burst-suppression or suppression with or without superimposed periodic discharges. Multimodal prognostication was performed 96 hours after CA. Good outcome at 6 months was defined as a modified Rankin Scale score of 0-3. RESULTS: 873 comatose patients at 59 sites had an EEG assessment during the hospital stay. Of these, 283 (32%) had good outcome. EEG was recorded at a median of 69 hours (IQR 47-91) after CA. Absence of highly malignant EEG patterns was seen in 543 patients of whom 255 (29% of the cohort) had preserved EEG reactivity. A non-highly malignant and reactive EEG had 56% (CI 50-61) sensitivity and 83% (CI 80-86) specificity to predict good outcome. Presence of EEG reactivity contributed (p<0.001) to the specificity of EEG to predict good outcome compared to only assessing background pattern without taking reactivity into account. CONCLUSION: Nearly one-third of comatose patients resuscitated after CA had a non-highly malignant and reactive EEG that was associated with a good long-term outcome. Reactivity testing should be routinely performed since preserved EEG reactivity contributed to prognostic performance.

Management of intractable bladder neck strictures following radical prostatectomy using the Memokath®045 stent.

The incidence of vesicourethral anastomotic stenosis (VUAS) post radical prostatectomy varies from 1 to 26%. Current treatment can be challenging and includes a variety of different procedures. These range from endoscopic dilations to bladder neck reconstruction to urinary diversion. We investigated a 2-stage endoscopic treatment, using the thermo-expandable Memokath®045 bladder neck stent to manage patients with VUAS post radical prostatectomy. We retrospectively reviewed 30 patients, between 2013 and 2017, who underwent a Memokath®045 stent insertion following failed primary treatment (dilation and clean intermittent catheterisation) for VUAS. The mean interval time between prostatectomy and Memokath®045 stent insertion was 13 months. The mean follow-up time was 3.6 years with all patients having a minimum of 12-month follow-up. All patients had two previous attempts at endoscopic dilatation with or without incision and a trial of clean intermittent catheterisation. During stage 1, the anastomotic stricture is dilated/incised to diameter of 30 Fr, the stricture length is measured, and a catheter is left in situ. One to 2 weeks later, post haemostasis and healing, an appropriately sized Memokath®045 stent is inserted. The stent is then removed 1-year post-op. Our series of patients had a median age of 62 (54-72). Most patients (26) had a robot-assisted radical prostatectomy (RARP) or salvage procedure. Results showed improvement in IPSS scores, IPSS quality of life scores, Qmax and PVR after the Memokath®045 stent was removed compared to pre-operation. With a minimum of 12 months post stent removal, 93% of patients were fully continent, whilst 7% of patients were socially continent. 2 (7%) patients had their stents removed and not replaced due to re-stricturing and stone formation. However, no urinary tract infections, stricture recurrence or urinary retention was observed in the rest of the cohort (93%). Overall, the Memokath®045 stent was successful in treating 93% of our patients with VUAS. Our series had minimal complications that were managed with conservative measures and in three patients' re-operation was needed. In conclusion, the Memokath®045 stent is a minimally invasive technique with faster recovery time compared to other techniques such as bladder neck reconstruction or urinary diversion. Additionally, it provides superior patency results compared to other techniques such as bladder neck incision and injection of Mitomycin C. Therefore, this management option should be considered in the management of VUAS.

The use ultrasound guided for refilling intrathecal baclofene pump in complicated clinical cases: A practical approach.

Muscular spasticity due to neurological disorders is a heavy cause of severe pain and disability for many patients, compromising the independence and quality life. Baclofene is a good tool to guarantee patients independence and pain control. Anyway in chronic therapy oral treatment become unsatisfactory. In all these cases, intrathecal baclofen therapy (ITB), after sub fascial implantation of intrathecal pumps is used as an important long term treatment to reduce spasticity. After pump implantation the drug reservoir must be refilled periodically in order to maintain the reduction of spasticity and avoid the symptoms and signs of withdrawal. ITB refilling, which involves the insertion of a needle through the skin until the access port of the pump, is often hard, mainly due to the layer of abdominal fat, spasticity, suboptimal pump positioning, pump rotation or inversion, and scar formation over the implantation site. To avoid the difficulties of ITB refilling radiography or other invasive supportive examinations are sometimes needed. We reported here our experience and we suggest a simple method to use the ultrasound in refilling with particular attention to some cases with complications after implantation with a difficult approach in refilling. We used the ultrasound examination to identify the access port of her pump so as to avoid multiple needle punctures and infections and radiation exposition. Ultrasound-guided technique may facilitate ITB refill in technically challenging cases. With ultrasound ITB was easily detectable and was quite simple to identify the exact point of needle injection. In the last years different new applications for ultrasounds are emerging. In our opinion the use of Doppler ultrasounds in the study of muscles and nerves represent an emerging tool for the physician's neurological rehabilitation.

An observational retrospective evaluation of 79 young men with long-term adverse effects after use of finasteride against androgenetic alopecia.

Concern regarding adverse effects of finasteride is increasing. We aimed to determine the type and frequency of symptoms in men having long-term sexual and non-sexual side effects after finasteride treatment (a condition recently called post-finasteride syndrome, PFS) against androgenetic alopecia (AGA). Subjects were recruited at the Urology Unit of the Trieste University-Hospital, and from a dedicated website. Out of 79 participants, 34% were white Italians, mean age was 33.4 ± 7.60 years, mean duration of finasteride use was 27.3 ± 33.21 months; mean time from finasteride discontinuation was 44.1 ± 34.20 months. Symptoms were investigated by an ad hoc 100 questions' questionnaire, and by validated Arizona Sexual Experience Scale (ASEX) and Aging Male Symptom Scale (AMS) questionnaires. By ASEX questionnaire, 40.5% of participants declared getting and keeping erection very difficult, and 3.8% never achieved; reaching orgasm was declared very difficult by 16.5%, and never achieved by 2.5%. By the ad hoc questionnaire, the most frequent sexual symptoms referred were loss of penis sensitivity (87.3%), decreased ejaculatory force (82.3%), and low penile temperature (78.5%). The most frequent non-sexual symptoms were reduced feeling of life pleasure or emotions (anhedonia) (75.9%); lack of mental concentration (72.2%), and loss of muscle tone/mass (51.9%). We contributed to inform about symptoms of PFS patients; unexpectedly loss of penis sensitivity was more frequent than severe erectile dysfunction and loss of muscle tone/mass was affecting half of the subjects. Further studies are necessary to investigate the pathophysiological and biochemical pathways leading to the post-finasteride syndrome.

Should older patients be offered varicocoele correction to improve their fertility?

We reviewed a large number of patients from 2000 to 2010 that underwent varicocoele correction using the retrograde sclerotization approach. Three hundred and seventy-six of them were included in the study, as they met the inclusion criteria. Mean age at the time of surgery was 32 years (SD: 6.5); 32% of them were 35 years and older. Patients were classified according to the clinical classification (GC) and Sarteschi's Doppler ultrasound classification (GS). The patients showed up at the clinic after an average time of 30 months of referred infertility related (SD: 28.54). Patients underwent pre-operative assessment with physical examination, sperm analysis and Doppler ultrasound, and again the same assessment at least 3 months after surgery. We evaluated the following parameters: sperm concentration (millions/mL, CONC), percentage motility (a+b, MOT) and the percentage of morphologically typical spermatozoa (MOR). Univariate and Multivariate analysis were performed. The research of Pearson's coefficients was performed to test the correlation between sperm parameters and age, SG, CG. Semen specimens were evaluated according to WHO 1999 criteria. Mean CONC varied from 34.5 to 47.0 millions/mL (+12.5; p < 0.001); MOT from 27.2 to 34.5% (+7.3%; p < 0.001); and MOR from 44.0 to 47.6% (+3.6%; p = 0.001). Univariable and multivariable analysis of variance related to age showed no significant difference of parameters improvement. Pearson's correlation coefficient for pre-operative and post-operative sperm MOT related to patients' age was respectively -0.11 (p < 0.001) and -0.18 (p = 0.04). No other significance was found. Usefulness of treating infertile patients affected by varicocoele is confirmed: varicocoele correction leads to significant sperm parameters improvement. There is no evidence of different improvement related to patients' age. The decline in sperm motility related to age of the patients seems to be only age-dependent: the usefulness of treating patients affected by varicocoele is not influenced by their age: treatment should also be offered to older patients.

Role of US in acute scrotal pain.

BACKGROUND: The acute scrotum is a common emergency department (ED) presentation and can be defined as any condition of the scrotum or intrascrotal contents requiring emergent medical or surgical intervention. Although rarely fatal, acute scrotal pathology can result in testicle infarction and necrosis, testicular atrophy, infertility, and significant morbidity. METHODS: Scrotal US is best performed with a linear 7.5- to 12-MHz transducer. In addition to imaging in the longitudinal and transverse planes, it is helpful to obtain simultaneous images of both testes for comparison. Color Doppler is used to evaluate for abnormalities of flow and to differentiate vascular from nonvascular lesions. Attention to appropriate color Doppler settings to optimize detection of slow flow is critical. RESULTS: The evaluation of acute scrotal pain can be challenging for the clinician initially examining and triaging the patient. Acute scrotal conditions due to traumatic, infectious, vascular, or neoplastic etiologies can all present with pain as the initial complaint. Additionally, the laboratory and physical examination findings in such conditions may overlap; this, coupled with potential patient guarding and lack of collaboration, may result in a limited, non-specific physical examination. Therefore, scrotal ultrasound has emerged to play a central role in the evaluation of the patient presenting with acute scrotal pain. CONCLUSIONS: In conclusion, we are firmly convinced that a scrotal ultrasound should always be performed in the presence of acute scrotal pain. Moreover, urologist should be able to perform a scrotal ultrasound but, if imaging does not supply a clear diagnosis, surgical exploration is still mandatory.
