Natural progression of hip dysplasia in newborns: a reflection of hip ultrasonographic screenings in newborn nurseries.

Hip screening is recommended for early detection of hip dysplasia; however, the strategy and efficacy were questioned. We performed ultrasonography to objectively observe the hip development in a group of infants and raise reflections on the efficacy of newborn ultrasonographic hip screening. A total of 1333 newborns (705 male and 628 female) received hip ultrasonography in the first week after birth. Clinical hip instability was detected by the Ortolani test. Hip dysplasia was defined by ultrasonography. A second survey of 90 babies was performed 1 month later on the babies with clinical hip instability or ultrasonographic Graf's type IIa, IIc, D, III, and IV hips. All the hip ultrasonographies were performed by the same investigator. Clinical instability was detected in 13 hips of 10 babies. Manual tests helped to detect unstable hips that had worse ultrasonographic measurements than those stable hips. Five Graf's type IIc hips and four type III hips were detected from the 2666 hips. At the age of 1 month, eight of the nine Graf's type IIc or III hips attained physiological status without treatment. A strong trend of spontaneous resolution in clinical hip instability and ultrasonographic dysplasia was observed in the newborns. The results did not support immediate treatment on the basis of newborn manual or ultrasound hip screening. We recommend manual testing in the newborn nursery to detect the hips at risk of dysplasia and ultrasonography after the first month after birth to confirm the diagnosis and judge the management.

Long-term results of autologous venous grafts for penile morphological reconstruction.

In order to evaluate the long-term results of autologous venous grafts, we present an overview of patients who underwent a procedure utilizing a venous patch from the deep dorsal vein with or without combination of the cavernosal vein in treating penile deformity. From March 1995 to March 2005, a total of 85 consecutive patients with Peyronie disease or congenital penile deviation underwent venous grafting. Tunical corporotomy was covered using transplanted venous wall sutured microscopically to collagen bundles of the inner circular and outer longitudinal layer of the tunica albuginea. The vein was sutured with the serosal side outward, after it had been detubularized, properly constructed, and spliced together. In this cohort, 48 patients with Peyronie disease and 37 with congenital penile deviation were respectively categorized as belonging to the Peyronie and congenital groups. All patients were evaluated preoperatively and postoperatively with the International Index of Erectile Function (IIEF-5) scoring, angle measurement of erectile penis, satisfaction with the penile shape, and a cavernosogram which was further available for 15 patients. Histological confirmation in 5 cases was followed up for up to 10 years. The mean angle improvement was 44.8 +/- 3.6 degrees for the Peyronie group and 37.6 +/- 3.8 degrees for the congenital group. A satisfactory penile shape was achieved in 77 (90.6%) patients, although 8 men (9.4%) complained of mild deviation of the penis (<15 degrees). Erectile function was good in 81 patients, although 6 of them had to use oral sildenafil/tadalafil postoperatively. Overall, they had a mean preoperative IIEF-5 score of 19.7 +/- 2.8, which increased to a mean postoperative score of 21.6 +/- 2.2. The cavernosograms consistently disclosed a good penile shape. The histological confirmation showed that the donor vein retained its histological character despite the fact that perfect coalescence and lining up with the tunica albuginea were noted. The autologous vein appears to be an acceptable graft material, and the transplanted vein may have a modeling action rather than a scaffolding role in venous patch surgery on the penile tunica albuginea. Careful microsurgical manipulation is required to achieve a satisfactory, sustainable outcome.

The advancement of pure local anesthesia for penile surgeries: can an outpatient basis be sustainable?

Although topical anesthetic blockage for penile surgeries has been substantially reported in the medical literature, its methodology, reliability, and reproducibility have not been consistent. We report on several methods of topical blocks for local anesthesia in patients with indications for penile surgeries. From March 1993 to March 2003, a total of 1131 men, ages 19 to 87, underwent penile surgeries in which 165, 203, 708, 45, and 10 patients received penile implantation, modified Nesbit procedure, venous surgery, venous patches, and arterial revascularization respectively, under pure local anesthesia on an outpatient basis. They were categorized into the implant, Nesbit, venous, patch, and arterial groups respectively. Proximal dorsal nerve blockage, peripenile infiltration, and topical injection, although challenging, were sufficient local anesthesia for patients in the last 4 patient groups. A new method of crural blockade, however, was also required for optimal anesthesia of the cavernous nerve for implantation purposes. The anesthetic effects and postoperative results were satisfactory. Common immediate side effects included puncture of the corpus spongiosum or the deep dorsal vein as well as the innominate vessel, subcutaneous ecchymosis, transient palpitations, and acceptable low level of pain. There were no significant late complications. In the implant group, however, 6.1% of patients (10/165) had experienced pain over the perineum for 1 to 2 weeks postoperatively. Overall there were statistical differences in scoring between the 5 groups in which the implant group stood out when a visual analog scale of 100 mm was used. Topical nerve blockades proved to be reliable, simple, and safe, with minimal complications. They offer the advantages of less morbidity, reduced effects of anesthesia, protection of privacy, and a rapid return to preoperative daily activity.
