Background: Dupuytren, Peyronie, and Ledderhose diseases are related fibroproliferative disorders characterized by abnormalities in the connective tissue of the palm of the hand, the tunica albuginea of the penis, and the sole of the foot, respectively. Concomitant prevalence rates of these diseases have only been described in a few small populations. This article aims to report on a large population and to raise awareness in surgeons treating Dupuytren disease for concurring related fibroproliferative disorders. Methods: Patients diagnosed as having Dupuytren disease were recruited from outpatient clinics in the northern part of the Netherlands from 2007 to 2016. Questionnaires concerning demographics, clinical characteristics, the coexistence of Ledderhose and/or Peyronie diseases, and other factors were filled in by the participants and by plastic surgeons. Results: For 730 men with Dupuytren disease, the surgeons’ reported prevalence rate of Peyronie disease was 7.8 percent and of Ledderhose disease was 16.1 percent. The participants themselves reported prevalence rates of 8.8 percent for Peyronie disease and of 22.0 percent for Ledderhose disease. Conclusions: In the Dupuytren patient cohort, the prevalence of Peyronie disease was lower than that described in the literature. The prevalence of Ledderhose disease corresponded with the rates from the literature. However, both were underreported by plastic surgeons, which calls for a rise in awareness, recognition, and referral to a urologist when the conditions are bothersome or symptomatic.
To evaluate the ability to obtain and the quality of orgasm after radical prostatectomy.The orgasms experienced after undergoing radical prostatectomy were evaluated in 20 men (median age 65 years, range 56-76) using a semi-structured interview and a self-administered questionnaire. In addition, the patients were asked to write a brief statement about their experiences and sensations during orgasm before and after the operation.Eighteen patients returned the questionnaire and 17 completed a statement indicating what their orgasm was like before and after radical prostatectomy. After the operation, no patient was able to maintain a completely rigid erection, but for five patients the erection was sufficient for sexual intercourse. Nine patients used a vacuum device or intracavernosal self-injection. Half the patients reported diminished sexual desire (libido) and arousal after the operation and reported the same to occur in their partners. During their "dry' orgasm post-operatively, none of the patients experienced the exquisite sensation of inevitability, the so-called "point of no return'. Seven of the 14 patients experiencing orgasm complained that their orgasmic sensation was weakened. Four patients reported normal pleasure and sensation compared to that experienced pre-operatively. Surprisingly, nine of the 14 patients had involuntary loss of urine at orgasm; for five of them this was sufficient reason to avoid any sexual contact with their partner.Radical prostatectomy may have serious consequences on libido and erectile function but sometimes other important factors, such as the absence of prostate and seminal vesicle contractions, the loss of ejaculation and involuntary loss of urine, may also compromise the orgasm.
Peyronie's disease (PD) is a fibroproliferative disease of the penis. Since little is known about the molecular pathogenesis of PD, we compared the biochemical make-up of PD plaques with normal tunica albuginea to clarify pathological processes in the scarred tissue. Protein and mRNA levels were measured in plaques and in unaffected pieces of the tunica albuginea. We investigated the presence of myofibroblasts, the deposition of collagens, and some key elements of Wnt and YAP1 signaling at protein level. The expression of 45 genes, all related to collagen homeostasis and extracellular matrix proteins, was quantified. In plaques, more myofibroblasts were present, and we observed an activation of Wnt signaling and YAP1 signaling. Increased levels of the collagens types I and III confirm the fibrotic nature of plaques. The mRNA ratio of collagen types III, IV, and VI to type I was increased. The expression of lysyl hydroxylase 3 was higher, whereas a decreased expression level was seen for fibronectin and cathepsin K. The biochemical composition of plaques was different from unaffected tunica albuginea: the relative and absolute abundance of various extracellular matrix proteins were changed, as well as the quality of collagen and the level of the collagen-degrading enzyme cathepsin K.
