Introduction Entrapment or strangulation of the penis is a rare emergency situation that can lead to a wide range of vascular and mechanical injuries. Aim The aim of this article is to present our experience dealing with penile strangulation. A review of the literature is also summarized in this report. Current treatment options and outcomes are also evaluated. Methods We performed a computerized MEDLINE search followed by a manual bibliographic review of cross-references. These reports were analyzed and the important findings summarized. Results Penile strangulation has been first time reported in 1755. Since that time, sporadic reports have appeared in the literature describing a variety of foreign bodies on the penis that have in common only the property of circularity. We noted motives, types of objects, types of strangulation, symptomatology, trauma grades, diagnoses, including psychological involvement, as well as possible treatment options. Furthermore, two cases of penile strangulation from our clinical practice are presented involving different degrees of vascular insult leading to different pathogenesis, clinical presentation, and surgical approach. Conclusion Penile strangulation is an unusual clinical condition and the consequences can be severe. Penile strangulation could lead to different degrees of vascular obstruction. Consequently, several clinical syndromes can occur: from mild nonsignificant vascular obstruction that resolves after decompression to severe gangrene of the penis accompanied with impaired renal function. The most common motive associated with foreign bodies on the penis is sexual or erotic in nature. The choice of method for removal depends upon type, size, incarceration time, trauma grade, and availability of the equipment. Prompt diagnosis and early treatment are essential to avoid the potential complications of ischemic necrosis and autoamputation.

We studied E-cadherin down-regulation at the protein level in frozen sections of 111 bladder tumours and 13 normal bladder specimens by means of immunohistochemistry, and at the mRNA level by semi-quantitative RT-PCR in 40 of the same tumours. Results indicate that E-cadherin expression detected by immunohistochemistry correlated with both stage and grade (P< 0.0001 and P< 0.001, respectively). Analysis of recurrence, progression and survival over a mean period of 36 months after surgery in the entire cohort showed that abnormal E-cadherin immunoreactivity correlated strongly with poor outcome (log-rank test: P = 0.001, P = 0.0001 and P = 0.0003, respectively). In multistep logistic regression analysis, only E-cadherin status and stage had significant additional prognostic value (P = 0.008 and OR = 0.2;P = 0.03 and OR = 3.6, respectively). Survival estimates derived from RT-PCR transcript quantification differed significantly for low and high expression (log-rank test: P = 0.0006). These results suggest that the alteration occurs at the transcriptional level and support the clinical and biological relevance of cell adhesion molecules in bladder cancer. © 2000 Cancer Research Campaign

Introduction Artificial penile nodules are defined as inert objects inserted beneath the skin of the penis to enhance the pleasure of female/male sexual partners during intercourse. Aim The aim of this article is to present our experience in dealing with artificial penile bodies. We have also reviewed the pertinent literature focusing on social, motivational, and occupational characteristics of individuals adopting this sexual practice, diagnostic dilemmas and the surgical and health side effects of the implantation of artificial penile nodules. Methods We performed a computerized MEDLINE search followed by a manual bibliographic review of cross-references. These reports were analyzed and the important findings summarized. Results The phenomenon of inserting self-made artificial nodules beneath the skin of the penis was first described in the Kama Sutra, the classic Indian treatise on love. It is most commonly observed among men from Southeast Asia. The occurrence is much less common in western cultures, but it has been reported to occur in Romania, Germany, and among Fijians and Russian immigrants in Israel. Furthermore, four cases of self-inserted artificial penile bodies from our clinical practice are presented and discussed. Conclusions The most common motive associated with foreign artificial bodies on the penis is sexual or erotic in nature and that is to enhance the pleasure of female or male sexual partners during sexual intercourse. Most of the reports involve members of low economic groups like gang members, soldiers, drug addicts, sailors, labor workers, and prisoners. Men suffer no serious side effects after insertion, although fixed beads can cause rupture of condoms. For women, the beads can cause abrasions and a few days of postcoital vaginal pain. Penis implants and inserts and other penis augmentation devices are potentially dangerous to both men and women, and of questionable value in bringing pleasure to either, and should be discouraged.
