Sleep-Related Painful Erections Following Sexual Intercourse

Sleep-related painful erections (SRPE) is a rare disorder characterized by recurrent painful nocturnal erections during REM sleep in the absence of pain during daytime erections. Approximately 35 cases of SRPE have been reported in the literature, none of them associated with preceding sexual intercourse. We add the report of a 40-year-old patient with a 6-year history of SRPE which only, but always, occurred after sexual intercourse with ejaculation in the evening before. As a result, the frequency of intercourse diminished, causing relationship problems. A non-pharmacological solution was found in shifting the time of sexual intercourse. The patient refused any proposed pharmacological treatment, because of "not wanting to be a patient at his age."

Prevalence of Peyronie and Ledderhose Diseases in a Series of 730 Patients with Dupuytren Disease

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

Glimpses into the molecular pathogenesis of Peyronie's disease

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

Verteporfin as a Medical Treatment in Peyronie's Disease

Introduction: In Europe and the United States, verteporfin (Visudyne; VP) is registered and used in treating macular degeneration. Research showed that VP decreased expression of fibrotic genes in fibroblasts collected from nodules of patients suffering from Dupuytren's disease, plausibly by de-activating transcription in the Yes Activated Protein (YAP) pathway. Aim: To analyze the effect of VP on myofibroblasts cultured from Peyronie's disease (PD) plaques. Methods: At surgery for PD we took biopsies from the plaques of 5 patients. By immunostaining, the presence of the pathologic myofibroblasts was determined. After culturing cells, VP was dispensed in starvation medium for 24 and 48 hours and messenger(m)RNA levels of COL1A1, ACTA2, COL5A1, EDA-FN, LOXL2, CCN2, SER-PINH1, PLOD2, and YAP were quantified and compared with controls with real-time polymerase chain reaction. Main Outcome Measure: mRNA-levels of COL1A1, ACTA2, COL5A1, EDA-FN, LOXL2, CCN2, SERPINH1, PLOD2, and YAP. Results: The pathologic phenotype of cells isolated from PD plaques was confirmed with baseline immunofluorescent stainings that showed considerable levels of a-smooth muscle actin, being a marker for the presence of myofibroblasts. The mRNA ratios of all the genes related to fibrosis (COL1A1, etc.) except YAP decreased significantly after treatment with VP within 24 and 48 hours. These results suggest inhibition of fibrosis in the YAP cascade, downstream of YAP. Conclusion: In our opinion, urologists must move the focus to disease before deformity, and the search for new oral or intralesional agents, well-tolerated and effective in both the acute and chronic phase of PD must continue. VP blocked the expression of genes related to fibrosis in the YAP cascade in myofibroblasts derived from PD plaque. Mohede DCJ, de Jong IJ, Bank RA, et al.

Sleep-Related Erections Throughout the Ages

Introduction. The occurrence of sleep-related erections (SREs) has been known since antiquity. Aim. To highlight historical, theological, and sexual medicine-related aspects of SREs throughout the ages. Methods. Review of old medical books on male sexual functioning and review of scientific medical and theological articles on SREs from about 1900 on. Results. The cyclic character of SREs was first noted by German researchers in the forties of the 20th century. However, already before the beginning of the Christian era, one knew that men had erections and ejaculations during sleep. In the Middle Ages, SREs were generally considered to be rebellious manifestations of the male body, while it seemed to disobey its owner and showed up its perverted and sinful side. From the fifteenth to the end of the 17th century, severe erectile dysfunction (ED) was ground for divorce. The ecclesiastical court records show that if necessary, the members of the jury sat at the defendant's bedside at night to be able to judge any SREs occurring. Since the 17th century, SREs were considered to be part of masturbation, which could cause many ailments and diseases. Psychoanalyst Stekel acknowledged in 1920 that a morning erection, the last SRE, is a naturally occurring phenomenon in healthy men from infancy to old age. Today, some scientists assume that SREs protect the integrity of the penile cavernous bodies. Conclusions. Throughout the ages, philosophers, theologians, physicians, members of ecclesial law courts, psychoanalysts, psychiatrists, sexologists, physiologists, and urologists have shown interest in SREs. Obviously, the observations and testing of SREs have a long history, from antiquity to modern sleep labs, in men and in women, in newborns and old adults, by penis rings with sharp spikes to fancy strain gauge devices. Despite all these efforts, the mechanisms leading to SREs and its function are however not yet completely understood

Type B Aortic Dissection After the Use of Tadalafil

A 63-year-old male patient with a type B aortic dissection after the use of tadalafil, a phosphodiesterase type 5 inhibitor, is presented. The possible role of a novel predisposing factor-sexual activity combined with tadalafil-is reviewed. This report and three other cases add a new dimension to the known predisposing factors such as chronic systemic hypertension, hereditary connective tissue diseases-and congenital aortic valve diseases. However, the precise role of phosphodiesterase type 5 inhibitors in the pathophysiology of aortic dissection remains unknown.
