Newborn pigs (n = 117) were used to provide information on the relationships of degree of asphyxia during delivery, viability at birth, and some striking aspects of postnatal vitality including survival, interval between birth and first udder contact and between birth and first suckling, rectal temperature at 24 h of life (RT24), and growth rate over the first 10 d of life. The degree of asphyxia at birth was estimated from cord blood pCO2, pH, and lactate levels. Onset of respiration, heart rate, skin color, and attempts to stand during the first minute after birth were used to estimate the viability score. Neonatal asphyxia, i.e., decreased blood pH and increased blood pCO2 and lactate, was associated with the production of unusually high levels of catecholamines. The degree of asphyxia increased with late position in the birth order (P < .01) and was higher in piglets born posteriorly (P < 0.5). Further, the average blood pCO2 within a litter increased (P < .05) with litter size. The was an inverse relationship between the degree of asphyxia and the viability score (P < .001). Highly viable piglets reached the udder more rapidly (P < .001) and had a higher RT24 (P < .001) than those of low viability. Plasma glucose concentrations increased with blood pCO2 and plasma epinephrine concentrations (P < .001). Neonatal asphyxia reduced postnatal vitality by delaying the first contact with the udder (P < .03) and was associated with a lower RT24 (P < .05), growth rate (P < .001), and survival over 10 d (P < 0.06). These variables, i.e., interval between birth and first udder contact, RT24, and growth rate, were correlated with birth weight (P < .001); RT24 was also shown to decrease (P < .001) with the time taken to reach the udder. Overall, results suggest that piglet suffering from asphyxia during delivery are less viable at birth and less prone to adapt to extrauterine life.

Purpose To evaluate the diagnostic accuracy of SelectMDx and its association with multiparametric magnetic resonance (mpMRI) in predicting prostate cancer (PCa) and clinically significant PCa (csPCa) on prostate biopsies among men scheduled for initial prostate biopsy. Methods In this single-center prospective study, 52 men scheduled for initial prostate biopsy, based on elevated total PSA level (> 3 ng/ml) or abnormal digital rectal examination, were consecutively included. All subjects underwent SelectMDx, PSA determination and mpMRI. Results SelectMDx score was positive in 94.1 and 100% of PCa and csPCa, respectively, and in only 8.6% of negative cases at biopsy. The probability for a csPCa at the SelectMDx score was significantly (p = 0.002) higher in csPCa (median value 52.0%) than in all PCa (median value 30.0%). SelectMDx showed slightly lower sensitivity (94.1 versus 100.0%) but higher specificity (91.4%) than total PSA (17.1%), and the same sensitivity but higher specificity than mpMRI (80.0%) in predicting PCa at biopsy. The association of SelectMDx plus mpMRI rather than PSA density (PSAD) plus mpMRI showed higher specificity (both 91.4%) compared to the association of PSA plus mpMRI (85.7%). In terms of csPCa predictive value, SelectMDx showed higher specificity (73.3%) than PSA (13.3%) and mpMRI (64.4%); as for the association of SelectMDx plus mpMRI (75.6%) versus PSA plus mpMRI (68.9%), the association of PSAD plus mpMRI showed the highest specificity (80.0%). Conclusion Our results of SelectMDx can be confirmed as significant but their impact on clinical practice together with a cost-effectiveness evaluation should be investigated in a larger prospective multicenter analysis.

Varicocele is the main cause of male infertility. Treatment stops continuous damage to spermatogenesis, thereby potentially improving fertility. Among all the available procedures, the antegrade scrotal sclerotherapy (ASS), a combined radiological-surgical approach first introduced by Tauber, is gaining more popularity due to its minimal invasiveness. We report the case of a 35-year old man who was subjected to a colonic resection after antegrade scrotal sclerotherapy for varicocele. The procedure was necessary due to the embolization of venous anastomosis between the spermatic and mesenteric veins, which were not detectable at the preoperative phlebography. IntroductionVaricocele represents the main cause of male infertility and leads to changes in testicular spermatogenesis in 60% to 70% of cases. Treatment prevents continuous damage to spermatogenesis, thereby potentially improving fertility. Successful treatment of varicocele improves semen quality in 40% to 60% of patients and recovers fertility in 10% to 40%.1 Among all the available procedures, the antegrade scrotal sclerotherapy (ASS) is a combined radiological-surgical approach first introduced by Tauber in 1988 2 and is usually performed under local anesthesia. The procedure starts with a short longitudinal scrotal incision at the base of the scrotum, isolation of the funiculum and identification of the most enlarged vein. Thereafter, a small incision of the vein allows for the insertion of a 23-gauge needle to perform a venogram by iodine contrast. In the end atoxysclerol mixed with air is injected. [2][3][4][5] This technique is well-established to treat varicocele. It is easier, faster and less invasive than open surgical and laparoscopic treatments.5 It results in a persistence rate as high as 9% in adults and 3% in children. 6 An analysis of seminal parameters showed a statistically significant improvement in the rate of fast progressive spermatozoa and reduction of immotile spermatozoa in patients who underwent ASS compared to open surgery. 5 Reported complication rates are low and they include scrotal hematoma, sterile epididymitis (due to paravascular application of the sclerosing agent), testicular atrophy (accidental sclerotherapy of the testicular artery), as well as intestinal 7 and abdominal wall necrosis (accidental sclerotherapy of the cremasteric artery). 2 Case reportA 35-year-old man presented with severe oligoasthenospermia and diagnosed with third grade varicocele on ultrasound. After we explained the therapeutic options to the patient, he agreed to undergo antegrade scrotal sclerotherapy. Incising the base of the scrotum, the funiculum was identified and the most enlarged vein was isolated and suspended between two slack sutures. A little incision of the vein was performed to insert a 23-gauge needle. The right position of the needle was checked by washing the vessel lumen with saline solution; the iodine contrast was then injected to perform a venogram (Fig. 1). Finally, during the Valsalva manoeuvre, 1 mL of air was injec...

We present the use of a modified corporoplasty, based on geometrical principles, to determine the exact site for the incision in the tunica or plaque and the exact amount of albuginea for overlaying to correct with extreme precision the different types of congenital or acquired penile curvature due to Peyronie's disease. To describe our experience with a new surgical procedure for the enhancement of penile curvature avoiding any overcorrection or undercorrection. Between March 2004 and April 2013, a total of 74 patients underwent the geometrical modified corporoplasty. All patients had congenital curvature until 90° or acquired stable penile curvature 'less' than 60°, that made sexual intercourse very difficult or impossible, normal erectile function, absence of hourglass or hinge effect. Preoperative testing included a physical examination, 3 photographs (frontal, dorsal and lateral) of penis during erection, a 10 mcg PGE1-induced erection and Doppler ultrasound, administration of the International Index of Erectile Function (IIEF-15) questionnaire. A follow-up with postoperative evaluation at 12 weeks, 12 and 24 months, included the same preoperative testing. Satisfaction rates were better assessed with the use of validated questionnaire such as the International Erectile Dysfunction Inventory of the Treatment Satisfaction (EDITS). Statistical analysis with Student's t-test was performed using commercially available, personal computer software. A total of 25 patients had congenital penile curvature with a mean deviation of 46.8° (range 40-90), another 49 patients had Peyronie's disease with a mean deviation of 58.4 (range 45-60). No major complications were reported. Postoperative correction of the curvature was achieved in all patients (100%). Neither undercorrection nor overcorrection were recorded. No significant relapse (curvature>15°) occurred in our patients. Shortening of the penis was reported by 74% but did not influence the high overall satisfaction of 92% (patients completely satisfied with their sexual life). The erectile function was analyzed in both groups, Student's t-test showed a significant improvement in erectile function, preoperative average IIEF-15 scores were 17.43±4.67, whereas postoperatively it was 22.57±4.83 (P=0.001). This geometrical modified Nesbit corporoplasty is a valid therapy which allows penile straightening. The geometric principles make the technique reproducible in multicentre studies.
