Redundant foreskin

During the last years it was shown that the aging process is controlled by specific genes in a large number of organisms (C. elegans, Drosophila, mouse or humans). To investigate genes involved in the natural aging process of the human skin we applied cDNA microarray analysis of naturally aged human foreskin samples. For the array experiments a non-redundant set of 2135 pre-selected EST clones was used. These arrays were used to probe the patterns of gene expression in naturally aged human skin of five young (3-4 years of age) and five old (68-72 years of age) healthy persons...

OBJECTIVE: To describe a technical modification that facilitates dorsal skin closure, improves cosmesis and eliminates chordee recurrence secondary to contracture of the dorsal penile skin in the repair of epispadias. PATIENTS AND METHODS: Eleven patients with penopubic epispadias (mean age 1.8 years) had the epispadias repaired using a modified ventral penile skin flap. Four patients had isolated epispadias and seven had had a previous primary closure of bladder exstrophy...

BACKGROUND/PURPOSE: Circumcision is the most commonly performed surgical procedure in the United States today. Despite the large number of specialists who perform this procedure, only occasionally are the results unsatisfactory. The purpose of this study is to review the indications for circumcision revision, attempt to identify the specialists who are performing unsatisfactory circumcisions, describe the authors' surgical technique for circumcision revision, and review current coding and billing issues related to this procedure...

PURPOSE: Evidence concerning the effect of circumcision on sexual function is lacking. Men circumcised as adults are potentially in a unique position to comment on the effect of a prepuce on sexual intercourse. We examine sexual function outcomes in men who have experienced sexual intercourse in the uncircumcised and circumcised states. MATERIALS AND METHODS: Men 18 years old or older when circumcised were identified by billing records during a 5-year period at an academic medical center...

While p53 activity is critical for a DNA damage-induced G(1) checkpoint, its role in the G(2) checkpoint has not been compelling because cells lacking p53 retain the ability to arrest in G(2) following DNA damage. Comparison between normal human foreskin fibroblasts (HFFs) and HFFs in which p53 was eliminated by transduction with human papillomavirus type 16 E6 showed that treatment with adriamycin initiated arrest in G(2) with active cyclin B/CDC2 kinase, regardless of p53 status. Both E6-transduced HFFs and control (LXSN)-transduced cells maintained a prolonged arrest in G(2); however cells with functional p53 extinguished cyclin B-associated kinase activity...

PURPOSE: A variant form of anterior hypospadias, called a megameatus and intact prepuce (MIP), is thought to be less amenable to conventional distal hypospadias repair. The feasibility of using the standard technique with a parameatal-based foreskin flap is described herein. MATERIALS AND METHODS: Nine children with the MIP variant underwent repair. A foreskin flap for urethroplasty was harvested from either the ventral (Mathiew) or unilateral site. The glans was split along with the cleft glanular groove to create the glans wings...

Involucrin was the first protein to be identified as a likely constituent of the insoluble cornified cell envelope (CE) of stratified squamous epithelia. However, to date, direct isolation from CEs of involucrin cross-linked by way of the transglutaminase-induced isopeptide bond has not been reported. We have treated human foreskin CEs with methanol/KOH (saponification) to hydrolyze off much of the lipids. By immunogold electron microscopy, this exposed large amounts of involucrin epitopes as well as of desmoplakin, a desmosomal structural protein...

In distal hypospadias without chordee, surgical correction has a purely cosmetic character. In contrast to standard techniques focusing on meatal position, parents often regard the redundant dorsal prepuce and its missing ventral fusion as the essential constituent of this malformation. The operative technique, presented in detail, emphasizes on foreskin reconstruction. The ventral adaption of the prepuce (VAP procedure) results in a penis with normal appearance. Complications presented reveal the importance of proper patient selection...

Authors report their experience of the treatment of anterior hypospadias which represent more than 71% of these cases operated all along the eight past years. The different aspects of these malformation are emphasized. For the majority of these cases the correction of the malformation may be obtained by a simple balanoplasty which gives the gland a normal form and height though directing the meatus forward; the redundant foreskin is excised and the penile skin torsion is corrected aligning the median raphe; a deficit of the ventral skin case be filled in with preputial flaps...

An 11-year-old patient with male pseudohermaphroditism presented with essentially normal-appearing female external genitalia. When examined, inguinal gonads, redundant foreskin, and some posterior labial fusion were found. Evaluation revealed basal testosterone (T) levels ranging from 65 to 107 ng/dl with slightly elevated serum gonadotropin levels (luteinizing hormone [LH]: 76 ng/ml, and follicle-stimulating hormone [FSH]: 568 ng/ml). Neither T nor its precursors increased with human chorionic gonadotropin (hCG) stimulation...

The majority of patients with distal hypospadias undergo surgical reconstruction in childhood for social, emotional, and technical reasons. Rarely, patients with hypospadias do not receive repair during childhood and seek surgical treatment as adults. The authors recently performed reconstruction on two adult patients with primary distal hypospadias. One patient had voiding problems, necessitating sitting, and the other patient desired repair for cosmetic reasons. In performing the surgical repair, the authors observed that the amount, as well as the elasticity, of the redundant foreskin was less in adults than in children...
