    Calciphylaxis is a rare life-threatening form of skin necrosis. Although traditionally observed in patients with end-stage renal disease and/or hyperparathyroidism, calciphylaxis has also been reported to occur in 'non-traditional' patients with normal renal and parathyroid function. We report a case of warfarin-induced calciphylaxis treated successfully with sodium thiosulphate and discuss the role of Vitamin K2 as a potential therapeutic option in the management of warfarin-induced calciphylaxis. © 2012 The Authors.

    2012-01-01

    Full Text Available Temporal artery calciphylaxis has rarely been described in chronic kidney disease patients on dialysis. We report a case of 72-year-old Caucasian man with multiple comorbidities and end-stage renal disease on dialysis who presented with temporal artery calcification leading to bilateral loss of vision followed by extensive skin lesions including one on glans penis. While on peritoneal dialysis, he developed anterior ischemic optic neuropathy, had no improvement on high dose steroids, and temporal artery biopsy showed marked calcification without any evidence of vasculitis. Few weeks later on hemodialysis, he developed widespread cutaneous lesions on extremities and penile necrosis with skin biopsy revealing calciphylaxis. On literature review of calciphylaxis in chronic kidney disease, we found only four cases of temporal artery calciphylaxis leading to anterior ischemic optic neuropathy and blindness. We believe this is the first case in which the rare temporal artery calciphylaxis and the uncommon penile necrosis are being described together. The objective is to emphasize the need to recognize this condition early in the CKD patients on dialysis presenting with visual symptoms as the different treatment strategies may help prevent complete loss of vision and also modify or prevent a full blown calciphylaxis.

    The radial forearm flap transfer has proved to be the standard technique in penile reconstruction. However, this operation still leads to a residual scar on the forearm. In the reconstruction of partial penis necrosis, achieving a desirable appearance and functional recovery while minimizing donor-site damage remains an unsolved problem. In this study, we report our experience using penile elongation combined with glanuloplasty to rebuild the partially necrotic penis.A retrospective review of a consecutive series of 33 patients with partial penis necrosis after microwave thermotherapy (not from our hospital) from December 2008 to May 2012 was conducted at the Department of Plastic and Reconstructive Surgery, Shanghai 9th People's Hospital. These patients, with an age range from 20 to 36 years, first underwent a scrotal skin flap transfer to cover residual cavernosum. The penis was simultaneously elongated at the proximal end. Six months later, all patients received glanuloplasty using expanded polytetrafluoroethylene that was implanted at the distal end of transferred scrotal skin flap to create the neoglans.Anthropometric measurements of preoperative and postoperative penile length were performed with an average follow-up period of 28 months. The mean extended penile length average was 2.57 cm, ranging from 3.16 to 5.73 cm. Patients' satisfaction rate was 88%. In addition, preoperative and postoperative photographs were reviewed for objective and subjective assessment of outcome parameters such as appearance of neophallus, urination, and erogenous sensation. Most importantly, the rebuilt penis postoperatively showed almost normal shape and restoration of basic physiologic function in most of the patients, with an acceptable complication rate. These preliminary results may provide a useful strategy for the reconstruction of a partially necrotic penis using a novel, simple, and effective approach.

    Full Text Available Penile paraffinoma is an uncommon entity produced by penile paraffin injections for the purpose of penile enlargement by a nonmedical person. Although it is not a current method of penile enlargement procedures, in our opinion dermatologists and urology specialist should be have knowledge of this entity about diagnosis and management. It will be an aim to share our experiences and views in this paper.

    Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years. Proper evaluation of both the primary lesion and lymph nodes is critical, because nodal involvement is the most important factor of survival. The NCCN Clinical Practice Guidelines in Oncology for Penile Cancer provide recommendations on the diagnosis and management of this devastating disease based on evidence and expert consensus.

    A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis. The biopsy result was thickening of the horny layer epidermis with only a foreign body granuloma composed of inflammatory cells, and did not lead to a definitive diagnosis. Thoraca-abdominal computed tomography revealed axillary lymphadenopathy with necrosis. Suspecting tuberculosis lymphadenitis, we performed T-spot and QuantiFERONtests. The result was T-spot negative and QuantiFERONpositive, so we diagnosed the patient with penile tuberculosis, and started antituberculosis medication. In about half a year after the start of treatment the symptoms subsided, and lymphadenopathy showed reduction.

  10. Penile enlargement surgery.

    Alter, G J

    1998-06-01

    Aesthetic surgery to improve the appearance of the penis, scrotum, and pubic region has successfully evolved. Penile lengthening is performed by releasing the suspensory ligament of the penis followed by use of penile weights. Girth is increased by wrapping a dermal-fat graft around the penile circumference. The choice of surgery is determined by the patient's anatomy and desires.

    A 64-year-old diabetic man on peritoneal dialysis developed painful necrotic ulcers of the glans penis over a period of six months. On suspicion of atherosclerotic necrosis, a partial resection of his penis was performed. Histological examination showed calciphylaxis. This vasculopathy...... with calcification and intimal fibrosis in small blood vessels is mostly seen in patients with end-stage renal disease. The condition is characterized by painful livedoid and infiltrated plaques and ulcers. Involvement of the penis is rare, but probably underdiagnosed. Udgivelsesdato: 2009-May-25...

    This review will highlight recent advances in the field of penile reconstructive surgery in the paediatric and adult population. It is based on the work published during the year 2001. Besides the anatomical and histological studies of the penis, major contributions have been described in congenital and acquired penile anomalies. Also, a few new techniques and modifications of old procedures are described in order to improve the final functional and aesthetic outcome. The techniques for penile enlargement present a trend in the new millennium, but are still at the stage of investigation.

  16. Penile pharmacoarteriography in impotence

    Bookstein, J.J.

    1986-01-01

    Conventional arteriography is unreliable in the evaluation of arteriogenic impotence, primarily because vasoconstriction of medium and small arteries can be indistinguishable from organic obstruction. Spinal anesthesia plus intracavernosal injections of papaverine can relieve vasoconstriction, but markedly increase the cost and complexity of penile arteriography. The authors have found that internal pudendal injection of papaverine and nitroglycerin provides effective dilation and allows penile arteriography to be performed on an outpatient basis. Arteriographic quality is further enhanced by selective internal pudendal injections, the use of highly concentrated nonionic agents, and direct magnification

  17. Low-level overexpression of p53 promotes warfarin-induced calcification of porcine aortic valve interstitial cells by activating Slug gene transcription.

    The most frequently used oral anti-coagulant warfarin has been implicated in inducing calcification of aortic valve interstitial cells (AVICs), whereas the mechanism is not fully understood. The low-level activation of p53 is found to be involved in osteogenic transdifferentiation and calcification of AVICs. Whether p53 participates in warfarin-induced AVIC calcification remains unknown. In this study, we investigated the role of low-level p53 overexpression in warfarin-induced porcine AVIC (pAVIC) calcification. Immunostaining, quantitative PCR, and Western blotting revealed that p53 was expressed in human and pAVICs and that p53 expression was slightly increased in calcific human aortic valves compared with non-calcific valves. Terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling staining indicated that apoptosis slightly increased in calcific aortic valves than in non-calcific valves. Warfarin treatment led to a low-level increase of p53 mRNA and protein in both pAVICs and mouse aortic valves. Low-level overexpression of p53 in pAVICs via an adenovirus vector did not affect pAVIC apoptosis but promoted warfarin-induced calcium deposition and expression of osteogenic markers. shRNA-mediated p53 knockdown attenuated the pAVIC calcium deposition and osteogenic marker expression. Moreover, ChIP and luciferase assays showed that p53 was recruited to the slug promoter and activated slug expression in calcific pAVICs. Of note, overexpression of Slug increased osteogenic marker Runx2 expression, but not pAVIC calcium deposition, and Slug knockdown attenuated pAVIC calcification and p53-mediated pAVIC calcium deposition and expression of osteogenic markers. In conclusion, we found that p53 plays an important role in warfarin induced pAVIC calcification, and increased slug transcription by p53 is required for p53-mediated pAVIC calcification. © 2018 by The American Society for Biochemistry and Molecular Biology, Inc.

    Background: Bleeding episodes commonly occur in patients on warfarin treatment even in those within therapeutic range of international normalized ratio (INR). The objective of this study was to investigate the effects of the 8 examined polymorphisms on the risk of bleeding complications in a sample of Iranian patients. Methods: A total of 552 warfarin treated patients who maintained on a target INR level of 2.0–3.5 for at least three consecutive intervals were enrolled from those attended our anticoagulation clinics. Ninety-two bleeding events were observed in 87 patients. The presences of the examined polymorphisms were analyzed using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). Results: Patients with the T allele in NQO1*2 (CT or TT genotypes) had a higher risk of bleeding than patients with the CC genotype (adjusted OR: 2.25, 95% CI: 1.37 to 3.70, P = 0.001). Those who were carriers of CYP2C9 one-variant haplotypes (*1/*2 or *1/*3) were also found to be associated with the higher risk of bleeding events. Compared to reference group (*1/*1), the odds of bleeding increased for carriers of one variant allele (*1/*2 or *1/*3) (adjusted OR: 1.75, 95% CI: 1.03 to 2.97, P = 0.039). Variant VKORC1, Factor VII, and EPHX1 genotypes were not significantly associated with the risk of bleeding events. Conclusion: The SNP C609T within NQO1 and haplotypes of CYP2C9 (1*2 or 1*3) are independently associated to bleeding complications of warfarin at normal INR. Further studies are required to confirm such associations in diverse racial and ethnic populations. - Highlights: • NQO1 C609T variant is associated with warfarin induced bleeding at therapeutic INR. • Haplotypes of CYP2C9 (1*2 or 1*3) are also associated with bleeding events. • VKORC1, Factor VII, and EPHX1 genotypes were not associated with bleeding risk.

    2013-01-01

    Full Text Available Fibrolipomas are a rare subtype of lipomas. We describe a case of a man suffering from subcutaneous penile fibrolipoma, who three months earlier has been submitted to an augmentative phalloplasty due to aesthetic dysmorphophobia. After six months from the excision of the mass, the penile elongation and penile enlargement were stable, and the patient was satisfied with his sexual intercourse and sexual life. To our knowledge, this is the first reported penile subcutaneous fibrolipoma case in the literature. The diagnostics and surgical features of this case are discussed.

    Objective was to present our experience with surgical and conservative management of penile fracture. This prospective study was carried out in the Urology and Nephrology Center, at Al-Thawra General and Teaching Hospital, Sana'a, Yemen from June 2003 to September 2007 and included 30 patients presenting with penile fracture. Diagnosis was made clinically in all our patients. Six patients with simple fracture were treated conservatively while 24 patients with more severe injuries were operated upon. Patient's age ranged from 24-52 years (mean 31.3 years) 46.7% of patients were under the age of 30 years and 56.7% were unmarried. Hard manipulation of the erect penis for example during masturbation was the most frequent mechanism of fracture in 53.3% of patients. Solitary tear was found in 22 patients and bilateral corporal tears associated with urethral injury were found in 2 patients. Corporal tears were saturated with synthetic absorbable sutures and urethral injury was repaired primarily. All operated patients described full erection with straight penis except 3 of the 8 patients who were managed by direct longitudinal incision, in whom mild curvature during erection was observed. The conservatively treated patients described satisfactory penile straightness and erection. The optimal functional and cosmetic results are achieved following immediate surgical repair of penis fracture. Good results can also be obtained in some selected patients with conservative management. (author)

  2. Penile Anomalies in Adolescence

    2011-01-01

    Full Text Available This article considers the impact and outcomes of both treatment and underlying condition of penile anomalies in adolescent males. Major congenital anomalies (such as exstrophy/epispadias are discussed, including the psychological outcomes, common problems (such as corporal asymmetry, chordee, and scarring in this group, and surgical assessment for potential surgical candidates. The emergence of new surgical techniques continues to improve outcomes and potentially raises patient expectations. The importance of balanced discussion in conditions such as micropenis, including multidisciplinary support for patients, is important in order to achieve appropriate treatment decisions. Topical treatments may be of value, but in extreme cases, phalloplasty is a valuable option for patients to consider. In buried penis, the importance of careful assessment and, for the majority, a delay in surgery until puberty has completed is emphasised. In hypospadias patients, the variety of surgical procedures has complicated assessment of outcomes. It appears that true surgical success may be difficult to measure as many men who have had earlier operations are not reassessed in either puberty or adult life. There is also a brief discussion of acquired penile anomalies, including causation and treatment of lymphoedema, penile fracture/trauma, and priapism.

  4. Penile embryology and anatomy.

    Yiee, Jenny H; Baskin, Laurence S

    2010-06-29

    Knowledge of penile embryology and anatomy is essential to any pediatric urologist in order to fully understand and treat congenital anomalies. Sex differentiation of the external genitalia occurs between the 7th and 17th weeks of gestation. The Y chromosome initiates male differentiation through the SRY gene, which triggers testicular development. Under the influence of androgens produced by the testes, external genitalia then develop into the penis and scrotum. Dorsal nerves supply penile skin sensation and lie within Buck's fascia. These nerves are notably absent at the 12 o'clock position. Perineal nerves supply skin sensation to the ventral shaft skin and frenulum. Cavernosal nerves lie within the corpora cavernosa and are responsible for sexual function. Paired cavernosal, dorsal, and bulbourethral arteries have extensive anastomotic connections. During erection, the cavernosal artery causes engorgement of the cavernosa, while the deep dorsal artery leads to glans enlargement. The majority of venous drainage occurs through a single, deep dorsal vein into which multiple emissary veins from the corpora and circumflex veins from the spongiosum drain. The corpora cavernosa and spongiosum are all made of spongy erectile tissue. Buck's fascia circumferentially envelops all three structures, splitting into two leaves ventrally at the spongiosum. The male urethra is composed of six parts: bladder neck, prostatic, membranous, bulbous, penile, and fossa navicularis. The urethra receives its blood supply from both proximal and distal directions.

  6. Penile suspensory ligament division for penile augmentation: indications and results.

    Li, Chi-Ying; Kayes, Oliver; Kell, Phillip D; Christopher, Nim; Minhas, Suks; Ralph, David J

    2006-04-01

    This study assessed the management of patients requesting penile length enhancement by division of the penile suspensory ligament. From September 1998 to January 2005, 42 patients with a variety of etiologies were included; all underwent division of the penile suspensory ligament. The outcome was assessed objectively based on increase in flaccid stretched penile length (SPL) and subjectively using the rates of patient satisfaction. The mean increase in SPL was 1.3+/-0.9 cm (range, -1 to +3 cm), with the addition of a silicone spacer placed between the pubis and penis giving a better outcome (p<0.05). The overall patient satisfaction rate was 35% but lower in the group with penile dysmorphic disorder at 27%. Division of the penile suspensory ligament or other augmentation techniques may increase penile length but usually not to a degree that satisfies the patient. Men with penile dysmorphic disorder often have unrealistic expectations regarding the outcome of surgical intervention and should be encouraged to seek psychological help primarily, with surgery reserved as the last resort.

    2005-01-01

    Purpose: To report results for 49 men with squamous cell carcinoma (SCC) of the penis treated with primary penile interstitial brachytherapy at one of two institutions: the Ottawa Regional Cancer Center, Ottawa, and the Princess Margaret Hospital, Toronto, Ontario, Canada. Methods and Materials: From September 1989 to September 2003, 49 men (mean age, 58 years; range, 22-93 years) had brachytherapy for penile SCC. Fifty-one percent of tumors were T1, 33% T2, and 8% T3; 4% were in situ and 4% Tx. Grade was well differentiated in 31%, moderate in 45%, and poor in 2%; grade was unspecified for 20%. One tumor was verrucous. All tumors in Toronto had pulsed dose rate (PDR) brachytherapy (n = 23), whereas those in Ottawa had either Iridium wire (n 22) or seeds (n = 4). Four patients had a single plane implant with a plastic tube technique, and all others had a volume implant with predrilled acrylic templates and two or three parallel planes of needles (median, six needles). Mean needle spacing was 13.5 mm (range, 10-18 mm), mean dose rate was 65 cGy/h (range, 33-160 cGy/h), and mean duration was 98.8 h (range, 36-188 h). Dose rates for PDR brachytherapy were 50-61.2 cGy/h, with no correction in total dose, which was 60 Gy in all cases. Results: Median follow-up was 33.4 months (range, 4-140 months). At 5 years, actuarial overall survival was 78.3% and cause-specific survival 90.0%. Four men died of penile cancer, and 6 died of other causes with no evidence of recurrence. The cumulative incidence rate for never having experienced any type of failure at 5 years was 64.4% and for local failure was 85.3%. All 5 patients with local failure were successfully salvaged by surgery; 2 other men required penectomy for necrosis. The soft tissue necrosis rate was 16% and the urethral stenosis rate 12%. Of 8 men with regional failure, 5 were salvaged by lymph node dissection with or without external radiation. All 4 men with distant failure died of disease. Of 49 men, 42 had an intact

The aim of this study is to describe our penile lengthening and widening procedures, the benefits and complications that could result from it. We perform these procedures since 1992 and treated close to 2000 patients. Thanks to our expertise and after succeeding in standardizing our techniques, we achieved a retrospective survey on 103 patients operated between 2004 and 2006. We describe here the two processes of our operating technique and we analyse the results obtained 1 month, 3 months and 1 year after the surgery. In most cases, combining a penis adipose tissue grafting, a suspensory ligament section and an adequate skin plasty is proven to be necessary in order to obtain both lengthening and widening increases. One year later, the increase is about 2.7 cm in length, corresponding to 28%, and 2.6 cm in circumference, corresponding to 27%. The complications (cutaneous necrosis, haematoma, lymphoedema, disharmonies), whenever they may exist, are most of the time spontaneously resolutive. Combining a penile fat tissue grafting with a suspensory ligament section allows us to answer to most of patients' expectations. However, several liposculpturing sessions might be necessary in order to get satisfactory results. Copyright 2009 Elsevier Masson SAS. All rights reserved.

  12. Penile Corporeal Reconstruction during Difficult Placement of a Penile Prosthesis

    Viet Q. Tran

    2008-01-01

    Full Text Available For some patients with impotence and concomitant severe tunical/corporeal tissue fibrosis, insertion of a penile prosthesis is the only option to restore erectile function. Closing the tunica over an inflatable penile prosthesis in these patients can be challenging. We review our previous study which included 15 patients with severe corporeal or tunical fibrosis who underwent corporeal reconstruction with autologous rectus fascia to allow placement of an inflatable penile prosthesis. At a mean follow-up of 18 months (range 12 to 64, all patients had a prosthesis that was functioning properly without evidence of separation, herniation, or erosion of the graft. Sexual activity resumed at a mean time of 9 weeks (range 8 to 10. There were no adverse events related to the graft or its harvest. Use of rectus fascia graft for coverage of a tunical defect during a difficult penile prosthesis placement is surgically feasible, safe, and efficacious.

  14. Our Results in Penile Fractures

    Tufan Süelözgen

    2016-06-01

    Full Text Available Introduction Penile fracture is a urological emergency caused by direct trauma to an erected penis, tearing the tunica albuginea in the corpus cavernosum. The preferred treatment method is draining the hematoma and surgical repair of tunica albuginea tear as soon as possible following diagnosis. Materials and Methods Forty-nine patients who were diagnosed with penile fracture between January 2009 and December 2014 were reviewed. Physical examination was performed to see the extent of penile hematoma, the side of the penile curvature and the presence of blood in the external meatus. Two patients who were diagnosed with urethrorrhagia underwent retrograde urethrogram for urethral injury. In all patients, penile skin was peeled using a circular subcoronal degloving incision and tunica tear was repaired using absorbable suture materials. The patients were then followed for painful erections, penile deformities and erection angles. Results The average age of the 49 patients, who were included in the study, was 36.5 years (21-65. In their etiological questioning, most patients reported the fracture occurring during sexual intercourse. Retrograde urethrography was indicated in 2 patients with blood in the external meatus and were diagnosed with urethral injury. The patients were taken to emergency surgery. Tunica defects varied between 1 and 2 cm. Incomplete urethral injuries were primarily repaired around 18 French Foley catheter. None of the patients reported penile deformity or painful erections. Their erection angles were found to be within the normal range. Conclusion Even though it is a relatively rare condition, penile fractures are so important that might cause serious complications when not treated surgically. A thorough anamnesis and physical examination suffice for diagnosis.

    Full Text Available Sarcoidosis is an inflammatory disease with unknown cause characterized by noncaseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, eye, and musculoskeletal system involvement. Rare involvement of the genital organs (prostate, testis, epididymis has also been reported. However, penile involvement is observed quite rare. In this paper, we report a patient with penile mass who was diagnosed with sarcoidosis on the basis of the laboratory, radiological, and pathological investigations.

  16. Penile gangrene following condom catheter urinary drainage : A case report

    2016-04-01

    Full Text Available External urine collecting devices have been a boon to patients of urinary incontinence since their invention in late 90s. They have replaced the need for uncomfortable indwelling catheters in these patients. As safe as they may be, ghastly complications have occurred infrequently, mostly due to their inappropriate application. Such penile and urethral complications add to the morbidity of the patients significantly. They can be easily avoided by following few simple steps of catheter care, thus emphasizing the need to aware clinicians and health care workers about the correct application methods. Here we discuss a case of 60 year old male who developed penile skin necrosis and urethral fistula due to chronic use of condom catheter.

  17. Isolated penile torsion in newborns.

    Eroglu, Egemen; Gundogdu, Gokhan

    2015-01-01

    We reported on the incidence of isolated penile torsion among our healthy children and our approach to this anomaly. Between 2011 and 2014, newborn babies with penile torsion were classified according to the angle of torsion. Surgical correction (penile degloving and reattachment for moderate cases and dorsal dartos flap technique in case of resistance) after 6 months was advised to the babies with rotations more than 45°. Among 1000 newborn babies, 200 isolated penile torsions were found, and among these, 43 had torsions more than 45°, and 4 of these had angles greater than 90°. The mean angle of the rotations was found 30.45° (median: 20°). In total, 8 children with 60° torsions were previously circumcised. Surgery was performed on 19 patients, with a mean patient age of 12 ± 2 months. Of these 19, 13 babies were corrected with degloving and reattachment. This technique was not enough on the remaining 6 patients; therefore, derotational dorsal dartos flap was added to correct the torsion. After a mean of 15.6 ± 9.8 months, residual penile rotation, less than 15°, was found only in 2 children. The incidence of isolated penile torsion is 20% in newborns. However, rotation more than 45° angles are seen in 4.3% of male babies. Correction is not necessary in mild degrees, and penile degloving with reattachment is enough in most cases. If the initial correction is insufficient, dorsal dartos flap rotation is easy and effective. Prior circumcision neither disturbs the operative procedure nor affects the outcomes.

  19. [Penile congenital abnormalities].

    Boillot, B; Teklali, Y; Moog, R; Droupy, S

    2013-07-01

    Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. A literature review was conducted on Medline considering the articles listed until January 2012. Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Penile tourniquet syndrome (PTS), a rare urologic emergency, may lead to undesirable results including necrosis and amputation of penis, if not diagnosed and treated appropriately. Sometimes these injuries may be accepted as a forensic case. Miscellaneous objects used for strangulation can be metallic or nonmetallic. Of all ages, the most vulnerable period is infancy. Telogen effluvium is the most common cause of PTS in infants who are 0–6 years old. In the literature, telogen effluvium as a reason of PTS was not found except for this age group. Therefore, we aimed to present a boy who is 8 years old diagnosed as PTS because of his mother's hair coil. PMID:25763288

    Penile cancer is a disease with a high morbidity and mortality. Its prevalence is relatively rare, but the highest in some developing countries. Insight into its precursor lesions, pathogenesis and risk factors offers options to prevent this potentially mutilating disease. This review presents an overview of the different histologically and clinically identified precursor lesions of penile cancer and discusses the molecular pathogenesis, including the role of HPV in penile cancer development. A systematic review of the literature evaluating penile carcinogenesis, risk factors and molecular mechanisms involved. Careful monitoring of men with lichen sclerosis, genital Bowen's disease, erythroplasia of Queyrat and bowenoid papulosis seems useful, thereby offering early recognition of penile cancer and, subsequently, conservative therapeutic options. Special attention is given to flat penile lesions, which contain high numbers of HPV. Their role in HPV transmission to sexual partners is highlighted, but their potential to transform as a precursor lesion into penile cancer has been unsatisfactorily explored. Further research should not only focus on HPV mediated pathogenic pathways but also on the non-HPV related molecular and genetic factors that play a role in penile cancer development. Options for prevention of penile cancer include (neonatal) circumcision, limitation of penile HPV infections (either by prophylactic vaccination or condom use), prevention of phimosis, treatment of chronic inflammatory conditions, limiting PUVA treatment, smoking cessation and hygienic measures.

    Penile amputation is a rare injury. Although, in principle, penile replantation can be performed using a variety of methods, few, if any, standardized procedures exist to deal with this medical emergency. The value of the various microsurgical techniques for replantation of the penis remains uncertain. This article provides a review of the management of penile defects and complications.

    2003-10-01

    We review our experience with the management of iatrogenic penile injuries. Apart from circumcision, serious damage to the penis can occur following hypospadias repair, surgery for priapism or total loss of the penis following surgical repair of bladder exstrophy. A retrospective analysis of patients with iatrogenic penile amputation referred to us between 1980 and 2000 was undertaken. Causes of injury and choice of management were reviewed. Of the 13 cases treated during the 20-year period mechanism of primary injury was circumcision in 4, hypospadias repair in 6, priapism in 1, bladder exstrophy repair in 1 and penile carcinoma in 1. A variety of techniques were used for phallic reconstruction. Penile degloving, division of suspensory ligament and rotational skin flaps achieved penile augmentation and enhancement. Reasonable cosmesis and penile length were achieved in all cases. In indicated cases microsurgical phalloplasty was technically feasible. However long-term followup showed various complications including erosions from the use of a penile stiffener. The ultimate goal of reconstructive surgery is to have a penis with normal function and appearance. The management of penile injury requires a wide variety of surgical techniques that are tailored to the individual patient. Expedient penile reconstruction is successful and therapeutic delay is associated with complications.

    The current literature provides a wide range of publications on the anthropometry of the penis specifying the relationship between penile dimensions and sex hormones, weight, height and erectile function. But most of the studies involved healthy volunteers or young patients with erectile dysfunction. Our study was conducted in patients with type 2 diabetes. Penile measurements obtained in the present study were compared those of the average Russian man. The patients were divided into groups with preserved and impaired erectile function. Erectile function was also studied relative to the variability of penile dimensions. The effect of DM duration on erectile function was defined. Comparative analysis revealed the relationship between penile anatomical dimensions and erectile function. We studied the effect of type 2 diabetes on the anatomical dimensions and elasticity of the penis, established the relationship between penile dimensions and elasticity of the penis. The correlation between the severity of erectile dysfunction and serum testosterone levels on one side, and penile dimensions on the other was found. The effect of penile dimensions on erectile function in DM patients was also examined. Determining penile dimensions and their variability due to various pathological conditions or processes, may eventually lead to better result of ED management.

  7. The status of penile enhancement procedures.

    Vardi, Yoram; Gruenwald, Ilan

    2009-11-01

    Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). This fact by itself leads to controversy regarding the true indications for penile enhancement procedures in men without micropenis. One of the typical aspects of penile enhancement is the lack of true methodological evaluation of the more commonly performed procedures. Even recently, only few solid scientific studies are available which can shed some light on results and outcome of these controversial procedures. Although some additional data has emerged during the past year, there is still no consensus in regard to indications and surgical techniques used for penile augmentation or penile girth enhancement. There is further need for more studies to provide a better overview of the value and worthiness of these procedures.

    2004-11-01

    Penile enhancement was performed using acellular dermal matrix. Multiple layers of acellular dermal matrix were placed underneath the penile skin to enlarge its girth. Since March 2002, penile augmentation has been performed on 12 cases using acellular dermal matrix. Postoperatively all the patients had a 1.3-3.1 cm (2.6 cm in average) increase in penile girth in a flaccid state. The penis had normal appearance and feeling without contour deformities. All patients gained sexual ability 3 months after the operation. One had a delayed wound healing due to tight dressing, which was repaired with a scrotal skin flap. Penile enlargement by implantation of multiple layers of acellular dermal matrix was a safe and effective operation. This method can be performed in an outpatient ambulatory setting. The advantages of the acellular dermal matrix over the autogenous dermal fat grafts are elimination of donor site injury and scar and significant shortening of operation time.

  9. Implantation of AMS 700 LGX penile prosthesis preserves penile length without the need for penile lengthening procedures

    2016-01-01

    Full Text Available Implantation of an inflatable penile prosthesis (IPP is a well-established definitive solution for erectile dysfunction when conservative treatments fail. Penile implants may shorten the penis. The AMS 700 LGX IPP is in common use but reports on its mechanical reliability, medium-term postsurgical patient satisfaction, and mean penile length preservation are lacking. We investigate the mean penile length, mechanical reliability, and patient satisfaction at 6 and 12 months after implantation of the AMS 700 LGX. This prospective study consecutively enrolled men undergoing first-time IPP implant surgery from February 2009 to April 2012. Stretched flaccid penile length, penile length at 50% and 100% of stiffness (P50 and P100 and International Index of Erectile Function (IIEF and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS scores, were measured at 6 and 12 months postsurgery. Of 45 patients who underwent AMS 700 LGX implantation (median age 61 years and completed 6 months′ follow-up, 36 (80% completed the study. A significant difference in stretched flaccid penile length was seen between 6 and 12 months (P = 0.033. P100 was also significantly increased at 6 and 12 months, with a mean 10% increase (1.3 ± 0.4 cm from baseline to 12 months. Differences in mean IIEF scores at 6 and 12 months were significant for the desired domain (P = 0.0001 and for overall satisfaction (P = 0.002; however, mean EDITS scores at 6 and 12 months were not significantly improved. AMS 700 LGX is a powerful tool for preserving penile length in men undergoing penile prosthesis implantation.

    2015-01-01

    Full Text Available Introduction: Physicians frequently encounter questions by parents regarding the normal size of a child′s penis. We evaluated normal variations of penile dimensions, correlation of penile length with height, weight, and body mass index (BMI of boys and analyzed the differences in penile dimensions from those reported from other countries. Materials and Methods: A cross-sectional study was conducted at our institution during October 2012-December 2012. A total of 250 subjects (birth to 10 years were evaluated and divided into 10 groups with 1-year interval taking 25 children in each. Penile dimensions measured twice by a single observer with Vernier calipers included the length of flaccid penis fully stretched and diameters at mid-shaft and corona. Diameters were multiplied by pi (π = 3.14 to calculate circumferences. Mean, standard deviation, and range were calculated. Height, weight, and BMI were noted and statistically correlated with the penile length using the Pearson correlation coefficient. Data were compared with similar studies reported on other populations in the past and individually evaluated with every study using Student′s t-test. Results: The mean values for the penile length, mid-shaft circumference, and coronal circumference were 3.34, 3.05, 3.29 cm during infancy, 4.28, 3.86, 4.11 cm during 4-5 years, and 5.25, 4.78, 5.05 cm during 9-10 years, respectively. The penile length increased with advancing age in successive age groups, but it did not have a direct correlation with either height, weight, or BMI. Penile dimensions in North Indian children were found to be statistically smaller in comparison with most studies from other countries. Conclusion: We provide the normal range and variations of penile dimensions in North Indian children.

    Full Text Available Penile hair tourniquet (PHT is a painless form of penile ischemia, typically seen in toddlers with long-haired mothers, caused by entanglement of hair on the balano-prepucial sulcus, normally associated with circumcision. Its association with hypospadias has been reported only once. A school-aged boy admitted for surgery to treat hypospadias failure was incidentally detected to have PHT and severe hourglass deformity of the penis. Urethral anastomosis and glanuloplasty were done after removal of the constricting ring, without complications. Normal erections were reported during follow up. Treatment may involve urethral reconstruction and penile reimplantation in extreme cases.

    2012-06-01

    Chronic penile lymphedema arises from the abnormal retention of lymphatic fluid in the subcutaneous tissues and may be secondary to local and systemic medical conditions such as sexually transmitted diseases, filariasis, malignancy, local radiotherapy, and surgery. This case report aims to consider compulsive masturbation as a possible cause of chronic penile edema. A 40-year-old man was referred to our institute for behavioral disturbance, including compulsive masturbation. Neuropsychiatric evaluation showed moderate mental retardation, mild dysarthria and limb incoordination, anxiety, depressed mood, and impulse dyscontrol. Brain MRI pointed out diffuse white matter lesions. Urogenital examination revealed an uncircumcised penis with non-tender edema of the shaft and prepuce with areas of lichenification. Since the most common local and systemic causes of edema were excluded, chronic penile edema due to compulsive masturbation was diagnosed and the compulsive behavior treated with an antidepressant and low-dose neuroleptics. Compulsive masturbation should be taken into account when counselling patients with penile edema.

    2011-01-01

    The authors describe a case of 33 year old Caucasian married man with an irregular 6 cm penile mass associated with multiple penile ulcers. He reluctantly admitted that 10 years ago he had multiple mineral oil (Vaseline) self injections into the penis, for penile enlargement purposes. The patient had a surgical intervention 10 years ago, but he has recurrent ulcers on his penis. We have administered an intravenous antibiotic therapy combined with local therapy. The term paraffinoma describes a distinct histopathological finding that results from the injection of foreign oily substances into the skin. Although such procedure may be considered rare, they are still performed in some countries. The major point we want emphasis is following: a lot of people seek penile augmentations, it is necessary to remind physicians and the public that nonscientific and inadequate procedure such as Vaseline may lead to debilitating and destructive consequences (Tab. 1, Ref. 12).

    Apprehension about the normal size of penis is a major concern for men. Aim of the present investigation is to estimate the penile length and circumference of Indian males and to compare the results with the data from other countries. Results will help in counseling the patients worried about the penile size and seeking penis enlargement surgery. Penile length in flaccid and stretched conditions and circumference were measured in a group of 301 physically normal men. Erected length and circumference were measured for 93 subjects. Mean flaccid length was found to be 8.21 cm, mean stretched length 10.88 cm and circumference 9.14 cm. Mean erected length was found to be 13.01 cm and erected circumference was 11.46 cm. Penile dimensions are found to be correlated with anthropometric parameters. Insight into the normative data of penile size of Indian males obtained. There are significant differences in the mean penile length and circumference of Indian sample compared to the data reported from other countries. Study need to be continued with a large sample to establish a normative data applicable to the general population.

    2016-01-01

    Full Text Available Penile fracture is the disruption of the tunica albuginea with rupture of the corpus cavernosum secondary to blunt trauma to the erect penis. It is an unusual condition, usually underreported. According to the published literature, vigorous vaginal intercourse with women on top position is the most common etiology across the globe including India with Middle Eastern countries being the exception. A total of seven patients of penile fracture presented in emergency in the last 6 months. The etiology was penile manipulation at the time of sexual excitement in six out of seven patients of penile fracture, which was contrary to the literature published except in Middle Eastern countries. All the patients were managed by emergency exploration and repair. Thus, the incidence and etiologies of penile fracture vary according to geographic region, sexual behavior, marital status, and culture.

    Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The aim of this article was to present the management of a case of a penile epidermal inclusion cyst that occurred because of late complications of a penile girth enhancement surgery. A 52-year-old man presented with a painless, slowly growing mass in the penis, which was first noted after a penile girth enhancement surgery 20 years ago. A cystic mobile mass about 2 cm in depth was found surrounding the coronal sulcus. Excision of the mass was performed for diagnosis and treatment. There was no communication with the urethra. The pathological diagnosis was an epidermal inclusion cyst of the penis. A penile epidermal inclusion cyst in adult men is rare. It can develop after an inadequate procedure for penile girth enhancement, and should be treated by complete resection.

    Fouad Aoun

    2015-01-01

    Full Text Available Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

  7. Stretch due to Penile Prosthesis Reservoir Migration

    E. Baten

    2016-03-01

    Full Text Available A 43-year old patient presented to the emergency department with stretch, due to impossible deflation of the penile prosthesis, 4 years after successful implant. A CT-scan showed migration of the reservoir to the left rectus abdominis muscle. Refilling of the reservoir was inhibited by muscular compression, causing stretch. Removal and replacement of the reservoir was performed, after which the prosthesis was well-functioning again. Migration of the penile prosthesis reservoir is extremely rare but can cause several complications, such as stretch.

  8. VEGF immunoexpression in penile carcinoma

    Antonio Carlos Pereira Martins

    2002-01-01

    Full Text Available OBJECTIVE: To investigate the vessel endothelial growth factor (VEGF as a risk factor in squamous cell carcinoma of the penis (SCCP. METHODS: Forty-seven patients with penile carcinoma were evaluated retrospectively. The mean age and standard deviation were 61.1±11.7 years. All of them were treated by penectomy and those with positive nodes underwent groin lymphadenectomy. Tumor grading was 35 G1 and 12 G2/3. Primary lesion stage was 24 pT1 and 23 pT2-4. Positive inguinal nodes were observed in 15 patients. Selected paraffin embedded sections were submitted to VEGF immunohistochemical analysis by the avidin-biotin-immunoperoxidase method with antigen retrieval. All slides were examined using an automatic analyzer system and the proportion of labeled cells in 10 high magnification power fields (400X were recorded in a blind analysis. RESULTS: Median (% labeling index was 2.3 in G1 versus 2.2 in G2/3 tumors (p=0.60, and 4.0 in pT1 versus 1.8 pT2-4 tumors (p=0.10. The respective data for pN0 patients was 2.8 and for pN+ was 2.1 (p=0.20. Survival curves showed no association with patients survival. CONCLUSION: In squamous cell carcinoma of the penis the VEGF immunoexpression has no association with tumor grade or stage, as well as with patient survival.

  9. Tubularized Penile-Flap Urethroplasty Using a Fasciocutaneous Random Pedicled Flap for Recurrent Anterior Urethral Stricture

    Yong Jig Lee

    2012-05-01

    Full Text Available This report describes the use of a tubularized random flap for the curative treatment of recurrent anterior urethral stricture. Under the condition of pendulous lithotomy and suprapubic cystostomy, the urethral stricture was removed via a midline ventral penile incision followed by elevation of the flap and insertion of an 18-Fr catheter. Subcutaneous buried interrupted sutures were used to reapproximate the waterproof tubularized neourethra and to coapt with the neourethra and each stump of the urethra, first proximally and then distally. The defect of the penile shaft was covered by advancement of the surrounding scrotal flap. The indwelling catheter was maintained for 21 days. A 9 month postoperative cystoscopy showed no flap necrosis, no mechanical stricture, and no hair growth on the lumen of the neourethra. The patient showed no voiding discomfort 6 months after the operation. The advantages of this procedure are the lack of need for microsurgery, shortening of admission, the use of only spinal anesthesia (no general anesthesia, and a relatively short operative time. The tubularized unilateral penile fasciocutaneous flap should be considered an option for initial flap urethroplasty as a curative technique.

  10. Penile artery shunt syndrome: a novel cause of erectile dysfunction after penile revascularization surgery.

    Pavlinec, Jonathan G; Hakky, Tariq S; Yang, Christopher; Massis, Kamal; Munarriz, Ricardo; Carrion, Rafael E

    2014-09-01

    Penile revascularization is a surgical treatment option for erectile dysfunction (ED) in healthy individuals due to a focal arterial occlusion in the absence of generalized vascular disease. Most described failures have been attributed to graft stenosis or disruption of the anastomosis. We report a novel phenomenon called Penile Artery Shunt Syndrome that contributed to persistent ED in a patient after penile microvascular arterial bypass surgery. A 26-year-old man presented for evaluation of long-standing ED, which was attributed to trauma sustained 12 years earlier. He had difficulty obtaining and maintaining erections despite oral pharmacotherapy. Clinical data related to the case were studied, analyzed, and reviewed with urologic and radiologic specialists at multiple centers that collaborated in the care of this patient. Penile duplex ultrasound peak systolic velocities and five-item International Index for Erectile Function questionnaire scores were the main outcome measures. Initial diagnostic workup of the patient confirmed severe insufficiency of the left cavernosal artery, with no evidence of venous leak. The patient underwent penile microvascular arterial bypass surgery with anastomosis of the left inferior epigastric artery to the left dorsal penile artery. The patient had persistence of severe ED despite patent anastomosis by penile duplex ultrasound. Subsequent arteriography revealed an arterial shunt due to an aberrant obturator artery arising from the donor inferior epigastric artery. The patient underwent embolization of the aberrant obturator artery, with resolution of the shunt and marked improvement in erectile function. The presence of an aberrant obturator artery arising from the inferior epigastric artery may predispose to persistent ED after revascularization due to the creation of a shunt phenomenon. Pelvic arteriography may be useful in identifying anomalous anatomic considerations prior to penile revascularization and to evaluate patients

  14. Penile Cancer: Contemporary Lymph Node Management.

    O'Brien, Jonathan S; Perera, Marlon; Manning, Todd; Bozin, Mike; Cabarkapa, Sonja; Chen, Emily; Lawrentschuk, Nathan

    2017-06-01

    In penile cancer, the optimal diagnostics and management of metastatic lymph nodes are not clear. Advances in minimally invasive staging, including dynamic sentinel lymph node biopsy, have widened the diagnostic repertoire of the urologist. We aimed to provide an objective update of the recent trends in the management of penile squamous cell carcinoma, and inguinal and pelvic lymph node metastases. We systematically reviewed several medical databases, including the Web of Science® (with MEDLINE®), Embase® and Cochrane databases, according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines. The search terms used were penile cancer, lymph node, sentinel node, minimally invasive, surgery and outcomes, alone and in combination. Articles pertaining to the management of lymph nodes in penile cancer were reviewed, including original research, reviews and clinical guidelines published between 1980 and 2016. Accurate and minimally invasive lymph node staging is of the utmost importance in the surgical management of penile squamous cell carcinoma. In patients with clinically node negative disease, a growing body of evidence supports the use of sentinel lymph node biopsies. Dynamic sentinel lymph node biopsy exposes the patient to minimal risk, and results in superior sensitivity and specificity profiles compared to alternate nodal staging techniques. In the presence of locoregional disease, improvements in inguinal or pelvic lymphadenectomy have reduced morbidity and improved oncologic outcomes. A multimodal approach of chemotherapy and surgery has demonstrated a survival benefit for patients with advanced disease. Recent developments in lymph node management have occurred in penile cancer, such as minimally invasive lymph node diagnosis and intervention strategies. These advances have been met with a degree of controversy in the contemporary literature. Current data suggest that dynamic sentinel lymph node biopsy provides excellent

    Cormio, Luigi; Di Fino, Giuseppe; Scavone, Carmen; Selvaggio, Oscar; Massenio, Paolo; Sanguedolce, Francesca; Macarini, Luca; Carrieri, Giuseppe

    2014-01-01

    Penile paraffinoma is a well-known delayed complication of paraffin oil injection into the penis for penile girth augmentation but its MRI features have not been previously described. A 35-year-old Ukraine man presented with erectile dysfunction, voiding difficulty and an irregular, hard and painful penile mass that had progressively grown over the last year. He reported having received, seven years before, several penile injections of paraffin oil for penile girth augmentation. On physical examination, the mass was tender, poorly delimited, and involved the whole penile shaft and the cranial part of the scrotum. Preoperative MRI, performed to determine the extent of tissue to be removed and the possibilities of penile reconstruction, showed a newly-formed homogeneous tissue, compressing but not infiltrating Buck’s fascia, iso-hypointense relative to muscle on T1-weighted sequences, and with a low signal intensity at T2-weighted sequences. On T1-weighted fat suppressed sequences, it did not enhance with contrast administration. MRI data were confirmed by surgical findings, as the newly-formed scar tissue did not infiltrate Buck’s fascia. Pathology confirmed the diagnosis of penile paraffinoma. MRI seems to provide an adequate imaging of the histological events occurring after injection of paraffin oil in the subcutaneous tissues. Penile paraffinoma remains a clinical diagnosis, but MRI features may be helpful in planning an adequate surgical strategy and, in selected cases, establishing the differential diagnosis with other penile diseases, including cancer

  16. Isolated Penile Torsion in Brothers: A Case Report

    Metin Gunduz

    2012-04-01

    Full Text Available Penile torsion can be congenital and associated with hypospadias and chordee, or can be acquired after circumcision. The incidence of isolated neonatal penile torsion was 1.7 to 27% in the literature. The majority were between 10 and deg; and 20 and deg;. Generally, torsion was to the left in cases. The techniques for correction of penile torsion described in the literature are penile de-gloving and reattaching of skin, resection of Buck's fascia incising the base of the penis and removing angular ellipses of corporeal tissue with subsequent plication of tunica, and dorsal dartos flap rotation in severe cases. In conclusion, penile torsion may be familial. Therefore, brothers should be examined carefully. The degloving and realignment technique is successful in isolated penile torsion.

  17. Role of penile doppler as a diagnostic tool in penile fracture

    Mohamed Azmi Hassali

    2018-01-01

    Full Text Available Penile fracture is defined as a traumatic rupture of either corpus cavernosum or the tunica albuginea; sometimes it can be both. It may be caused by exotic masturbation acts, sexual intercourse, or other trauma to this area. This can be accompanied by injury to the urethra, which is the cause of hematuria as a symptom for some patients. Typically, diagnosis of penile rupture or fracture depends on clinical examination and history told by the patients. We are stating the importance of medical imaging in the diagnosis of patients with penile fracture by presenting a case of patient suffered from penile fracture after a fall on his penis where it affected the erection of two-third of his penis. In which, the proper diagnosis by imaging studies and taking actions accordingly can save the patients from unnecessary surgeries that indeed increase the bill of the medical care directly and indirectly. Therefore, most patients can be diagnosed cost-effectively and treated surgically without a need to delay surgery, which is often the case if one was to resort to other investigations. Investigations such as retrograde urethrography for suspected urethral injury should only be used when the diagnosis of penile fracture is in doubt.

    2011-01-01

    Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    2013-01-01

    Objective: To describe the management and outcome of patients with penile fracture. Study Design: Case series. Place and Duration of Study: Department of Urology and Renal Transplantation, Jinnah Hospital, Lahore, from March 2008 to March 2011. Methodology: Sixteen patients presenting with clinical findings / history of penile fracture were included in this study. Diagnosis was made on the basis of history and clinical findings. Surgical exploration and repair was done on the same day. In all patients, a subcoronal circumferential degloving incision was made. Rent location and dimensions management and postoperative complication were noted. Postoperatively, erection was suppressed for 4 - 5 days. All patients were discharged with advice of avoidance of sex for about 8 weeks. Patients were followed-upto 6 months. Results: Majority of the patients (87.5%) were married and 13 (81.25%) were aged 18 - 45 years. The typical findings recorded in 100.0% patients were erection at time of fracture, detumescence, swelling and ecchymosis. Audible crackling sound and pain was present in 13 (81.25%) patients. Ten (62.5%) patients had rent in the proximal part of penile shaft and right lateral tear was present in 11 (68.75%) patients. Blood clots were evacuated and closure of rent was done with vicryl 2/0 (interrupted stitches). 100.0% patients had uneventful recovery with only 3 (18.75%) patients developed right chordae of erect penis after treatment. All (100.0%) patients were potent and without any problem of erection. Conclusion: Penile fracture is under-reported. A trauma to erect penis is essential to cause fracture. Surgical exploration and repair is the treatment of choice. (author)

  3. Methotrexate in the treatment of penile carcinoma.

    Sklaroff, R B; Yagoda, A

    1980-01-15

    Eight patients with epidermoid carcinoma of the penis received methotrexate, five with high-dose methotrexate, 250--1500 mg/m2 with citrovorum rescue Q 2--4 weeks, and three with low-dose methotrexate, 0.5--3.0 mg/kg weekly. Three (38%) patients achieved a complete or partial remission which persisted for 11, 3 and 2 months, respectively. Methotrexate appears to be an active agent in the treatment of advanced penile cancer.

  5. Synergism of clinical evaluation and penile sonographic imaging in diagnosis of penile fracture: a case report

    Bello Jibril

    2012-09-01

    Full Text Available Abstract Introduction Penile fracture is an uncommon urologic emergency, and is the traumatic rupture of the tunica albuginea covering the corpus cavernosa. This usually occurs following blunt trauma sustained during coitus, masturbation or self-manipulations to hide or suppress an erection. Clinical diagnosis can often be easily made with typical history and examination findings. However, the patient may present atypically and/or with a suspicion of associated urethral injury. The roles of various diagnostic investigations are being evaluated in these situations. Case presentation We report the case of a 31-year-old African man with penile fracture and suspected associated urethral injury that occurred after self-manipulations to hide an erection. Conclusions Penile ultrasound and sonourethrography provide useful additional diagnostic information to supplement clinical history and physical examination findings and can be performed easily, at low cost and with no delays to surgery.

Methods: Data of 52 patients who underwent penile prosthesis implantation in single center between May 2010 and December 2015 were retrospectively analyzed. Types of prosthesis, complication and satisfaction rates of patients were recorded by EDITS (Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was used. Results: The mean age was 49.2±14.7 years for patients. The mean follow-up durations for 34.3±12.5 months. The mean hospital stay was 3.84±1.52 days. Evaluating of the couples satisfaction revealed that 44 (84% of the patient were very satisfied. There was not any complication and no patient need to underwent revision surgery. Conclusion: Inflatable penile prosthesis implants, with high levels of treatment success, patient and partner sat­isfaction, are effective and safe options for treatment of organic erectile dysfunction with acceptable complication and revision rates.

  7. PENILE ENHANCEMENT PROCEDURES: UROLOGICAL AND ETHICOLEGAL ISSUES

    Marco Vella

    2012-04-01

    Full Text Available Phalloplasty procedures for most men requiring penile augmentation surgery are cosmetic procedures; generally the patients have a normal-sized and fully functional penis but they think that their penis is too small. There are not well defined indications for penile enhancement surgery and, except for the treatment of “micropenis”, there are not established guidelines and the outcome measures for success are still unclear. All penile enhancement techniques often do not reach the expected result and the grade of patient’s satisfaction is frequently poor. Phalloplasty procedures for psychological dysmorfism are not approved by any scientific society and the majority of these procedures are performed in private settings. The ethical and medicolegal problems resulting from a penis enhancement can be various and numerous, but few of them are reported in literature. After phalloplasty an attribution of professional responsibility and request of reimbursement is not rare. In this contribution the authors summarize a panorama of several urological and medico-legal aspects related to phalloplasty procedures.

    Ajit Somaji Sawant

    2016-01-01

    Full Text Available Penile injury due to constriction by a foreign object is a rare known complication, commonly seen in pediatric age group. We report four cases of penile constriction injury in adults due to various foreign objects and different indications. Between October 2014 and March 2016, four patients (mean age 42.5 years presented with penile constriction injury with duration at presentation ranging from 18 h to 2 months. One patient had complete transection of the corpus and penile urethra. Three patients were managed successfully with daily dressings followed by split-skin grafting in one patient. One patient required delayed primary suturing after the resolution of local edema. The outcome was satisfactory in all patients with retained erectile function. Early medical attention and management is the key to success in penile constriction injury cases and to avoid complications and morbidity. Prompt removal can be challenging in cases of metal foreign bodies.

    2016-06-01

    We present a cadaveric dissection study to investigate the anatomic feasibility of penile transplantation. Seventeen male cadavers were dissected to reveal detailed anatomy of the dorsal neurovascular structures including dorsal arteries, superficial and deep dorsal veins, and dorsal nerves of the penis. Dorsal artery diameters showed a significant decrease from proximal to distal shaft. Dominance was observed in one side. Deep dorsal vein showed a straight course and less decrease in diameter compared to artery. Dorsal nerves showed proximal branching pattern. In a possible penile transplantation, level of harvest should be determined according to the patient and the defect, where a transgender patient will receive a total allograft and a male patient with a proximal penile defect will receive a partial shaft allograft. We designed an algorithm for different levels of penile defect and described the technique for harvest of partial and total penile transplants.

Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period. Materials and Methods: A retrospective study was conducted. We reviewed all penile biopsies performed between January 1, 2007 and December 31, 2015 and studied the causes of the nonvenereal penile dermatoses. Results: The sample included a total of 108 patients, aged 62.9 (±17.8 years, between 16 years and 96 years of age. Eighteen dermatoses were identified. Inflammatory diseases were present in 65. 7% of patients (71/108 and neoplastic dermatoses in 34. 3% (37/108. Concerning inflammatory dermatoses, the most frequent were Zoon balanitis (27.8%, 30/108, followed by lichen sclerosus (15.7%, 17/108, psoriasis (11.1%, 12/108, and lichen planus (4.6%, 5/108. In patients with psoriasis, 10 had lesions only in the penis, similarly to all patients with lichen planus. The most frequent malignant tumor was squamous cell carcinoma (SCC (15.7%, 17/108. The most common in-situ tumor was erythroplasia of Queyrat (8.3%, 9/108. A case of basal cell carcinoma (BCC was found. Kaposi sarcoma and mycosis fungoides on penis were also diagnosed, as an additional form of presentation to their generalized disease. Conclusions: In this study, inflammatory diseases were the most frequently diagnosed dermatoses, while SCC was the most common malignant tumor found. In the majority of psoriasis and lichen planus cases, clinical lesions were only present in the genital area.

    It has been suggested that the application of penile-extender devices increases penile length and circumference. However, there are a few scientific studies in this field. The aim of this study was to assess the efficacy of a penile-extender (Golden Erect(®) , Ronas Tajhiz Teb, Tehran, Iran) in increasing penile size. This prospective study was performed on subjects complaining about "short penis" who were presented to our clinic between September 15, 2008 and December 15, 2008. After measuring the penile length in flaccid and stretched forms and penile circumference, patients were instructed to wear Golden Erect(®) , 4-6 hours per day during the first 2 weeks and then 9 hours per day until the end of the third month. The subjects were also trained how to increase the force of the device during determined intervals. The patients were visited at the end of the first and third months, and penile length and circumference were measured and compared with baseline. The primary end point of the study was changes in flaccid and stretched penile lengths compared with the baseline size during the 3 months follow-up. Twenty-three cases with a mean age of 26.5 ± 8.1 years entered the study. The mean flaccid penile length increased from 8.8 ± 1.2 cm to 10.1 ± 1.2 cm and 10.5 ± 1.2 cm, respectively, in the first and third months of follow-up, which was statistically significant (P penis (9.3 ± 0.86 cm vs. 8.8 ± 0.66 cm, P penis girth enhancement using penile extender.

    To search for an optimal strategy for the treatment of penile and scrotal gangrene by analyzing the clinical effect of vacuum sealing drainage (VSD) as an adjuvant treatment on this disease. We retrospectively analyzed the clinical data about 4 cases of penile and scrotal gangrene treated by VSD as an adjuvant treatment from January 2015 to June 2016. The 4 patients all underwent early extensive and radical debridement of gangrene of the scrotum and penis and received intravenous injection of two broad-spectrum antibiotics, followed by VSD for wound drainage and irrigation. Adequate wound drainage was achieved in all the 4 cases, the gangrene range rapidly localized and testicular necrosis avoided. The wound surface healed satisfactorily after cleansing and suturing. The patients were followed up for 3 months after discharged from the hospital and none experienced recurrence. VSD combined with early adequate debridement can effectively localize the gangrene range, significantly reduce the frequency of changing dressings and shorten the hospitalization time of the patient, and therefore is a very effective adjuvant treatment of penile and scrotal gangrene.

    Full Text Available Os anticoagulantes orais que atuam através do antagonismo à vitamina K são utilizados na prática clínica há muito tempo, porém ainda há dificuldades no seu manejo e na condução das complicações. Entre as complicações, as mais conhecidas são os transtornos hemorrágicos, mas outras também devem ser reconhecidas, tais como a necrose induzida por varfarina. Esta é uma grave, porém rara complicação, cuja fisiopatologia é ainda obscura e cujas causas são indefinidas. Dentre as possíveis causas, as mais prováveis são a deficiência de proteína C e de proteína S, reações de hipersensibilidade e deficiência de fator VII. Há maior incidência desta complicação entre mulheres de meia-idade, acometendo preferencialmente mamas e glúteos. As medidas mais importantes para o tratamento são: suspensão imediata da droga, uso de heparina não fracionada ou de baixo peso molecular em doses terapêuticas, emprego da vitamina K e, eventualmente, infusão de plasma fresco congelado ou de proteína C ativada recombinante.Oral anticoagulants acting via vitamin K antagonists have long been employed in the clinical practice. However, difficulties related to the management of treatment regimens and complications still persist. Among the complications, bleeding disorders are widely known, but others should also be taken into consideration, such as warfarin-induced skin necrosis. The pathophysiology of this rare but severe complication is still obscure, and its causes remain to be defined. Among possible causes, protein C and protein S deficiency, hypersensitivity reactions and VII factor deficiency are the most probable ones. There is an increased incidence of warfarin-induced skin necrosis among middle-aged women, usually affecting breasts and buttocks. The most important treatment measures are immediate discontinuation of the drug, use of unfractionated or low-molecular-weight heparin at therapeutic doses, use of vitamin K and

    We developed a new surgical model of penile girth enhancement in dog, with minimal damage, fewer complications, and high success rate, to enable the experimental investigation of penile implants. We obtained materials for penile girth enhancement by processing the pericardium and blood vessel wall collected from pigs. Incisions were made at the penile bulb for the implantation of the materials, and facilitate observation and data collection, based on the anatomical features of dog's penis. We measured the girth of the flaccid penis before and after the operation, and erectile function at 1-month postoperation. In addition to evaluation of recovery from the incision and local pathological changes, ultrasonic examination was performed to monitor the long-term changes associated with implantation. The mean girth of the flaccid penis significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm postoperation. Dogs resumed normal mating at 1 month after the operation, without any significant change in the mating time. Ultrasonic examination clearly illustrated the implants, and helped in the measurement of the distance between the materials and the baculum. Chinese Rural dog is a promising animal model for penile girth enhancement surgery. The findings demonstrated that surgical implantation into penile bulb was associated with less damage, faster postoperative recovery, and higher success. For the first time, ultrasonic examination provided objective data on the surgical outcomes of penile girth enhancement.

  4. Imaging of penile traumas - therapeutic implications

    Bertolotto, Michele; Calderan, Loretta; Cova, Maria Assunta [Universita di Trieste, UCO di Radiologia, Trieste (Italy)

    2005-12-01

    Injury to the penis may result from penetrating or nonpenetrating trauma. Nonpenetrating injury to the erect penis can produce albugineal tear, intracavernous hematoma or extraalbugineal hematoma from rupture of the dorsal vessels. Nonpenetrating injury to the flaccid penis usually follows blunt perineal traumas producing extratunical or cavernosal haematomas, or cavernosal artery tear followed by high flow priapism. Differential diagnosis between albugineal tear and other penile injuries must be obtained as soon as possible, since early surgical repair of albugineal tear reduces significantly the rate of postraumatic curvature and fibrosis. Ultrasonography (US) is able to detect the exact site of the tear in most patients as an interruption of the thin echogenic line of the tunica albuginea. Other imaging techniques are rarely required in the clinical practice. Color Doppler US is the imaging modality of choice to evaluate patients with high flow priapism. Focal or diffuse cavernosal fibrosis can be identified with US as echogenic areas in the cavernosal bodies. Postraumatic erectile dysfunction can result from fibrotic changes, nerve and vascular impairment or both. Doppler evaluation of penile vasculature is required in young patients with postraumatic impotence before surgical revascularization procedures. (orig.)

  5. Penile implants among prisoners-a cause for concern?

    Lorraine Yap

    Full Text Available BACKGROUND: We report the prevalence of penile implants among prisoners and determine the independent predictors for having penile implants. Questions on penile implants were included in the Sexual Health and Attitudes of Australian Prisoners (SHAAP survey following concerns raised by prison health staff that increasing numbers of prisoners reported having penile implants while in prison. METHODS: Computer-Assisted Telephone Interviewing (CATI of a random sample of prisoners was carried out in 41 prisons in New South Wales and Queensland (Australia. Men were asked, "Have you ever inserted or implanted an object under the skin of your penis?" If they responded Yes: "Have you ever done so while you were in prison?" Univariate logistic regression and logistic regression were used to determine the factors associated with penile implants. RESULTS: A total of 2,018 male prisoners were surveyed, aged between 18 and 65 years, and 118 (5.8% reported that they had inserted or implanted an object under the skin of their penis. Of these men, 87 (73% had this done while they were in prison. In the multivariate analysis, a younger age, birth in an Asian country, and prior incarceration were all significantly associated with penile implants (p<0.001. Men with penile implants were also more likely to report being paid for sex (p<0.001, to have had body piercings (p<0.001 or tattoos in prison (p<0.001, and to have taken non-prescription drugs while in prison (p<0.05. CONCLUSIONS: Penile implants appear to be fairly common among prisoners and are associated with risky sexual and drug use practices. As most of these penile implants are inserted in prison, these men are at risk of blood borne viruses and wound infection. Harm reduction and infection control strategies need to be developed to address this potential risk.

  6. The relation between sexual orientation and penile size.

    Bogaert, A F; Hershberger, S

    1999-06-01

    The relation between sexual orientation and penile dimensions in a large sample of men was studied. Subjects were 5122 men interviewed by the Kinsey Institute for Research in Sex, Gender, and Reproduction from 1938 to 1963. They were dichotomously classified as either homosexual (n = 935) or heterosexual (n = 4187). Penile dimensions were assessed using five measures of penile length and circumference from Kinsey's original protocol. On all five measures, homosexual men reported larger penises than did heterosexual men. Explanations for these differences are discussed, including the possibility that these findings provide additional evidence that variations in prenatal hormonal levels (or other biological mechanisms affecting reproductive structures) affect sexual orientation development.

    Diphallus (penile duplication) is very rare and seen once every 5.5 million births. It can be isolated, but is usually accompanied by other congenital anomalies. Previous studies have reported many concurrent anomalies, such as bladder extrophy, cloacal extrophy, duplicated bladder, scrotal abnormalities, hypospadias, separated symphysis pubis, intestinal anomalies and imperforate anus; no penile duplication case accompanied by omphalocele has been reported. We present the surgical management of a patient with multiple anomalies, including complete penile duplication, hypo-gastric omphalocele and extrophic rectal duplication.

    Full Text Available Penile augmentation has been reported in the literature by injecting various materials. This study reports our experience in management of penile augmentation complications associated with selfpenile injection of silicone liquid. After a careful ultrasound study, the penile skin was excised through a circumferential sub-coronal incision and dissected with the silicon mass. Histology was well-compatible with silicone granulomas. The patient was discharged after 24 hours. Ultrasonography has permitted preoperatively to determine if the plane between the indurated inflammatory tissue and the Buck’s fascia was preserved for the complete surgical excision of affected tissue.

    A review of the current state of knowledge is made on sonographic evaluation of penile in patients with erectile dysfunction. This sonography is developed with high resolution ultrasound on gray scale, combined with color Doppler ultrasonography; which the arteries of penile are examined before and during the erection. The penile ultrasonography has meant an important tool in the evaluation of specific patients who have submitted erectile dysfunction, particularly, in those with record of trauma and history of Peyronie's disease. In addition, through a sonographic evaluation has permitted to prove manifestations of the pathophysiological phenomena of the patient in order to establish their classification and guide their treatment [es

    2015-05-01

    Full Text Available Although a rare occurrence, this event may occur as a result of self-mutilation among individuals with psychiatric disturbances or due to work-related accidents, iatrogenic injuries or the actions of individuals motivated by jealously, rage and feelings of betrayal. In western societies, most penile amputations are the result of self-aggression during a psychotic episode, the treatment of victims involves resuscitation, stabilization and immediate psychiatric support. The amputated tissue must be preserved under hypothermic conditions. Micro-surgery is currently the most widely employed method for penile replantation. This paper describes a successful case of penile replantation following 5 hours of warm ischemia.

    2013-09-01

    To evaluate the changing cavernosal length of patients with diabetes mellitus (DM) and organic erectile dysfunction (ED) who were treated with inflatable, three-piece penile prostheses, a current surgical treatment option in our clinic, over the course of 12 years. Between April 2000 and December 2012, we retrospectively investigated data from patients who were diagnosed with organic ED and undergone penile prosthesis implantation (PPI). Of the 239 patients, 235 of them were included in the study. Four patients who were operated on for trans-sexuality were excluded from the study. All patients were divided into two groups as those with (Group 1) or without DM (Group 2). Data, including age, body mass index (BMI) in kg/m(2), surgical history, comorbidities, International Index of Erectile Function (IIEF) questionnaire scores, combined intracavernous injection and stimulation (CIS) test results, length of corpus cavernosum while implanting the penile prosthesis, complications, operative times, mean hospital stay, and satisfaction of the patient and partner, were recorded. Kruskal-Wallis and Mann-Whitney U tests were used for statistical analysis. A p-value of 0.05). The length of the corpus cavernosum and the destruction of cavernosal tissues do not depend only on DM. We conclude that these features may have multifactorial causes.

  15. Penile herpes zoster: an unusual location for a common disease

    Milan Bjekic

    Full Text Available Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    Full Text Available Angiosarcoma is a very rare mesenchymal tumor of penis. Though extremely unusual, it should be considered in the differential diagnosis in patients presenting with a penile growth or a localized subcutaneous penile lesions as they are very aggressive and there is a high chance of recurrence. One such case is reported here, which was aggressively treated with total penectomy and the patient did not show any recurrence in 2 years of follow-up.

  18. Managing the difficult penile prosthesis patient.

    Trost, Landon W; Baum, Neil; Hellstrom, Wayne J G

    2013-04-01

    Inflatable penile prostheses (IPPs) are associated with excellent long-term outcomes and patient/partner satisfaction. A small percentage of patients remain dissatisfied, despite acceptable surgical results. This study aims to evaluate factors associated with patient satisfaction and dissatisfaction, define patient characteristics, which may identify elevated risk of postoperative dissatisfaction, and describe management strategies to optimize functional and psychological patient outcomes. A review of urologic and non-urologic cosmetic surgery literature was performed to identify factors associated with patient satisfaction/dissatisfaction. Emphasis was placed on articles defining "high risk" or psychologically challenging patients. Preoperative factors associated with patient satisfaction/dissatisfaction and character traits, which may identify elevated risk of postoperative dissatisfaction or otherwise indicate a psychologically challenging patient. Contemporary patient and partner satisfaction rates following IPP are 92-100% and 91-95%, respectively. Factors associated with satisfaction include decreased preoperative expectations, favorable female partner sexual function, body mass index ≤30, and absence of Peyronie's disease or prior prostatectomy. Determinants of dissatisfaction include perceived/actual loss of penile length, decreased glanular engorgement, altered erectile/ejaculatory sensation, pain, diminished cosmetic outcome, difficulty with device function, partner dissatisfaction and perception of unnatural sensation, complications, and extent of alternative treatments offered. Personality characteristics which may indicate psychologically challenging IPP patients include obsessive/compulsive tendencies, unrealistic expectations, patients undergoing revision surgery, those seeking multiple surgical opinions, feeling of entitlement, patients in denial of their prior erectile/sexual function and current disease status, or those with other psychiatric

  19. Reconstruction of deformities resulting from penile enlargement surgery.

    Alter, G J

    1997-12-01

    More than 30 patients presented for reconstruction of penile deformities secondary to penile enlargement surgery performed by other physicians. Lengthening was performed by releasing the suspensory ligament of the penis and advancing pubic skin with a V-Y advancement flap. Girth was increased by injecting autologous fat. Specific complaints relating to the lengthening procedure involve hypertrophic and/or wide scars, a proximal penile hump from a thick, hair-bearing V-Y flap, and a low hanging penis. Complications relating to autologous fat injections include disappearance of fat, penile lumps and nodules, and shaft deformities. The repair of these deformities is described. From 1994 through October 1996, 19 men underwent 24 various combinations of reconstructive operations, such as scar revisions, V-Y advancement flap reversal, and removal of fat nodules and asymmetrical fat deposits. Penile appearance and function were improved. Complications include 1 hematoma requiring drainage, minor wound complications and 1 inadequately reversed V-Y flap. The methods of various repairs are discussed, including reconstructive limitations, timing and staging. Significant improvement can be achieved with proper reconstruction of penile deformities.

  20. A critical analysis of penile enhancement procedures for patients with normal penile size: surgical techniques, success, and complications.

    Vardi, Yoram; Har-Shai, Yaron; Harshai, Yaron; Gil, Tamir; Gruenwald, Ilan

    2008-11-01

    Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high

  1. Ischemic necrosis and osteochondritis

    Weissman, S.D.

    1989-01-01

    Osteonecrosis indicates that ischemic death of the cellular constituents of bone and marrow has occurred. Historically, this first was thought to be related to sepsis in the osseous segments. However, continued studies led to the use of the term aseptic necrosis. Subsequent observations indicated that the necrotic areas of bone were not only aseptic, but were also avascular. This led to the terms ischemic necrosis, vascular necrosis and bone infarction. Ischemic necrosis of bone is discussed in this chapter. It results from a significant reduction in or obliteration of blood supply to the affected area. The various bone cells, including osteocytes, osteoclasts, and osteoblasts, usually undergo anoxic death in 12 to 48 hours after blood supply is cut off. The infarct that has thus developed in three-dimensional and can be divided into a number of zones: a central zone of cell death; an area of ischemic injury, most severe near the zone of cell death, and lessening as it moves peripherally; an area of active hyperemia and the zone of normal unaffected tissue. Once ischemic necrosis has begun, the cellular damage provokes an initial inflammatory response, which typically is characterized by vasodilatation, transudation of fluid and fibrin, and local infiltration of flammatory cells. This response can be considered the first stage in repair of the necrotic area

    . It is concluded that penile lymphoscintigraphy is a valid and well-tolerated method for lymphatic mapping and SN identification. Although bilateral early inguinal drainage is the most frequent pattern, late imaging is recommended principally in patients with initial unilateral drainage in order to exclude delayed lymph node filling in the contralateral groin. SN identification may lead to a more accurate staging and avoid extensive lymph node dissection in the majority of patients with penile carcinoma. (orig.)

    We have developed a penile nonimaging scintillation (PNIS) probe consisting of a plastic well-type scintillation crystal interfaced to a portable computer and acquisition board. This report describes the design of the PNIS probe, performance characteristics, mode of usage and illustrative results which demonstrate its capabilities. With the PNIS probe, penile blood-pool studies were performed in nine patients utilizing 3.7 MBq (100 microCi) autologous 99mTc-labeled red blood cells (RBCs). Venous blood standards were assayed to enable conversion of the count rate to volummetric measurements. Washin of peripherally administered 99mTc-RBCs was mathematically analyzed to estimate penile blood volume and cavernosal flow rate in the flaccid state. The rate of change of penile blood volume after intracavernosal vasodilators was used to generate measures of stimulated flow. A major advantage of this device over the gamma-camera is a 3300-fold increase in count rate sensitivity, which allows for markedly improved temporal resolution while significantly reducing the radiopharmaceutical dosage. Additionally, the PNIS probe is portable, economical and is not dependent on operator-defined regions of interest. Count rate sensitivity is relatively constant within the bore, with the exception of the proximal region adjacent to the opening, where geometric efficiency is reduced. The PNIS probe is an effective device for measuring penile activity in radionuclide studies, allowing for acquisition of time-activity curves of the penis during flaccid washin of peripherally labeled red blood cells and after pharmacologic stimulation to induce erection.

    Conclusions: There is an increased utilization of penile prosthetics in Saudi Arabia. The private sector performs the majority of penile prosthesis procedures, and most of them are of the semirigid type. The governmental sector is more likely to perform inflatable penile prosthesis and male incontinence device procedures. Male incontinence prosthetics' use is very limited in Saudi Arabia.

    Invasive penile cancer is a rare disease with an approximately 22 000 cases per year. The incidence is higher in less developed countries, where penile cancer can account for up to 10% of cancers among men in some parts of Africa, South America, and Asia. To describe the human papillomavirus (HPV) DNA prevalence, HPV type distribution, and detection of markers of viral activity (ie, E6*I mRNA and p16(INK4a)) in a series of invasive penile cancers and penile high-grade squamous intraepithelial lesions (HGSILs) from 25 countries. A total of 85 penile HGSILs and 1010 penile invasive cancers diagnosed from 1983 to 2011 were included. After histopathologic evaluation of formalin-fixed paraffin-embedded samples, HPV DNA detection and genotyping were performed using the SPF-10/DEIA/LiPA25 system, v.1 (Laboratory Biomedical Products, Rijswijk, The Netherlands). HPV DNA-positive cases were additionally tested for oncogene E6*I mRNA and all cases for p16(INK4a) expression, a surrogate marker of oncogenic HPV activity. HPV DNA prevalence and type distributions were estimated. HPV DNA was detected in 33.1% of penile cancers (95% confidence interval [CI], 30.2-36.1) and in 87.1% of HGSILs (95% CI, 78.0-93.4). The warty-basaloid histologic subtype showed the highest HPV DNA prevalence. Among cancers, statistically significant differences in prevalence were observed only by geographic region and not by period or by age at diagnosis. HPV16 was the most frequent HPV type detected in both HPV-positive cancers (68.7%) and HGSILs (79.6%). HPV6 was the second most common type in invasive cancers (3.7%). The p16(INK4a) upregulation and mRNA detection in addition to HPV DNA positivity were observed in 69.3% of HGSILs, and at least one of these HPV activity markers was detected in 85.3% of cases. In penile cancers, these figures were 22.0% and 27.1%, respectively. About a third to a fourth of penile cancers were related to HPV when considering HPV DNA detection alone or adding an HPV

    Sarkis, Pierrot E; Sadasivam, Muthurajan

    2007-12-01

    To determine the incidence of isolated neonatal penile glanular torsion, describe the basic characteristics, and explore the relationship between foreskin and glans torsion. A prospective survey was conducted of all male newborns admitted to nursery after delivery, or neonates less than 3 months presenting for circumcision. Cases with associated genital malformations were excluded. The incidence of isolated neonatal penile torsion was 27% (95% CI: 22.2%-31.84%), to the left in 99% of cases. In 3.5% of cases, the penis had an angle 20 degrees. Using Spearman's correlational coefficient, deviation of penile raphe from the midline at the foreskin tip had a better correlation with glans torsion than deviation of raphe at the coronal sulcus (0.727 vs 0.570; both significant at pscope of the study.

    2006-01-01

    Full Text Available OBJECTIVE: To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. MATERIALS AND METHODS: The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospectively analyzed. RESULTS: Of 43 cases assessed, 41 were submitted to surgical exploration (95.3% and 2 were submitted to conservative treatment (4.7%. We found penile lesions involving the corpus cavernosum in 37 cases; the remaining 4 patients presented no lesions involving the corpus cavernosum, urethra or testicles but did in the superficial structures. Ten cases presented an association with testicular lesions and 14 cases association with anterior urethral lesions. CONCLUSION: Penile lesions from gunshot wounds should be treated with immediate surgical intervention. In exceptional situations featuring superficial lesions only conservative treatment may be applied.

  12. Henoch-Schonlein purpura: ultrasonography of scrotal and penile involvement

    Youngsik Lim

    2015-04-01

    Full Text Available Testicular or scrotal involvement has been reported in children with Henoch-Schonlein purpura (HSP, but there are very few reports on penile involvement. We report the initial and follow-up ultrasonographic findings of scrotal and penile involvement of HSP in a 5-year-old boy. On ultrasonography, scrotal soft tissue thickening and epididymal swelling with increased vascularity were noted, and on the penis, a focal mass-like lesion appeared on the dorsal surface of the distal penis, having a hypoechoic mass-like appearance without visible vascular flow on a Doppler study. After 2 days of treatment, follow-up ultrasonography showed normal scrotum and penis with a resolved soft tissue mass-like lesion. Therefore, we think that HSP ultrasonographic findings involving the scrotum and penis might help to diagnose scrotal and penile involvement in a case of HSP and to avoid unnecessary medication and/or surgical procedures.

  13. [Effectiveness of penile ventral scrotum cohesion place wedge cutting and improved Brisson technique for congenital buried penis].

    Zhang, Huafeng

    2013-09-01

    To investigate the effectiveness of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique for congenital buried penis. Between March 2010 and June 2012, 68 boys with congenital buried penis were treated by the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique, with a median age of 4 years and 10 months (range, 3 months-13 years). Of 68 cases, 14 were classified as phimosis type, 14 as rope belt type, 20 as moderate type, and 20 as severe type. The body of penis developed well and had no deformity. After operation, complications were observed, and the effectiveness was evaluated by the designed questionnaire. Early postoperative complications occurred in 11 cases, including obvious adhesion of the outside wrapping mouth in 4 cases, scrotal skin bloat in 5 cases, and distal foreskin necrosis in 2 cases; long-term complications occurred in 9 cases, including abdominal incision scar formation in 4 cases, wrapping mouth scar stricture in 3 cases, and short penis in 2 cases. Primary healing of incision was obtained in the other boys. Fifty-four cases were followed up 6-12 months (mean, 8 months). According to the designed questionnaire, satisfaction rate with the overall view in parents was 77.78% (42/54); the clinical improvement rate was 85.19% (46/54); exposure of the penis was satisfactory in parents of 50 cases; and the parents had no psychological burden of penis exposure in 46 cases, which were significantly improved when compared with preoperative ones (P penis exposure in 29 cases (53.70%) after operation, showing no significant difference when compared with preoperative one (18 cases, 33.33%) (chi2 = 1.22, P = 0.31). Application of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique can effectively correct congenital buried penis.

  14. Penile representations in ancient Greek art.

    Rempelakos, L; Tsiamis, C; Poulakou-Rebelakou, E

    2013-12-01

    The presentation of the cult of phallus in ancient Greece and the artistic appearance of the phenomenon on vase figures and statues, as indicative of the significant role of the male genitalia in all fertility ceremonies. The examination of a great number of penile representations from the ancient Greek pottery and sculpture and the review of the ancient theater plays (satiric dramas and comedies ). Phallus in artistic representation is connected either with gods of fertility, such as the goat-footed and horned Pan or the ugly dwarf Priapus or the semi-animal nailed figures Satyrs, devotees of the god Dionysus accompanying him in all ritual orgiastic celebrations. Phallus also symbolizes good luck, health and sexuality: people bear or wear artificial phalli exactly like the actors as part of their costume or carry huge penises during the festive ritual processions. On the contrary, the Olympic gods or the ordinary mortals are not imaged ithyphallic; the ideal type of male beauty epitomized in classical sculpture, normally depicts genitals of average or less than average size. It is noteworthy that many of these images belong to athletes during or immediately after hard exercise with the penis shrunk. The normal size genitalia may have been simply a convention to distinguish normal people from the gods of sexuality and fertility, protectors of the reproductive process of Nature. The representation of the over-sized and erected genitalia on vase figures or statues of ancient Greek art is related to fertility gods such as Priapus, Pan and Satyrs and there is strong evidence that imagination and legend were replacing the scientific achievements in the field of erectile function for many centuries.

  15. Femoral head avascular necrosis

    Chrysikopoulos, H.; Sartoris, D.J.; Resnick, D.L.; Ashburn, W.; Pretorius, T.

    1988-01-01

    MR imaging has been shown to be more sensitive and specific than planar scintigraphy for avascular necrosis (AVN) of the femoral head. However, experience with single photon emission CT (SPECT) is limited. The authors retrospectively compared 1.5-T MR imaging with SPECT in 14 patients with suspected femoral head AVN. Agreement between MR imaging and SPECT was present in 24 femurs, 14 normal and ten with AVN. MR imaging showed changes of AVN in the remaining four femoral heads. Of these, one was normal and the other three inconclusive for AVN by SPECT. The authors conclude that MR imaging is superior to SPECT for the evaluation of AVN of the hip

  3. Steatocystoma simplex in penile foreskin: a case report.

    de Lima, Mário Maciel; de Lima, Mário Maciel; Granja, Fabiana

    2016-03-08

    Steatocystoma simplex is an uncommon skin lesion with a histological pattern that is identical to that of steatocystoma multiplex. We are reporting this case of steatocystoma simplex for its uncommon location in the penile foreskin, and its occurrence in a Wapishana man. A 56-year-old man of Wapishana ethnicity presented with complaints of referred penile discomfort and pain during sexual intercourse for 5 years. A physical examination revealed a mobile, compressible subcutaneous non-tender mass of 4 cm diameter located on the left-side of his penile foreskin. There were no signs of inflammation, no grip on the penile shaft, and no urethral discharge or enlargement of lymph nodes. We found no evidence of other cysts on cutaneous examination. We performed classical excision of the lesion under local anesthesia and confirmed the diagnosis of steatocystoma with the pathological report. As there were no complications, we discharged him the same day. Steatocystoma can be considered a differential diagnosis for cystic lesions on and around the penis.

  4. Optimizing Penile Length in Patients Undergoing Partial Penectomy for Penile Cancer: Novel Application of the Ventral Phalloplasty Oncoplastic Technique

    Jared J. Wallen

    2014-10-01

    Full Text Available The ventral phalloplasty (VP has been well described in modern day penile prosthesis surgery. The main objectives of this maneuver are to increase perceived length and patient satisfaction and to counteract the natural 1-2 cm average loss in length when performing implantation of an inflatable penile prosthesis. Similarly, this video represents a new adaptation for partial penectomy patients. One can only hope that the addition of the VP for partial penectomy patients with good erectile function will increase their quality of life. The patient in this video is a 56-year-old male who presented with a 4.0x3.5x1.0 cm, pathologic stage T2 squamous cell carcinoma of the glans penis. After partial penectomy with VP and inguinal lymph node dissection, pathological specimen revealed negative margins, 3/5 right superficial nodes and 1/5 left superficial nodes positive for malignancy. The patient has been recommended post-operative systemic chemotherapy (with external beam radiotherapy based on the multiple node positivity and presence of extranodal extension. The patient’s pre-operative penile length was 9.5 cm, and after partial penectomy with VP, penile length is 7 cm.

  5. Penile prosthesis implant: scientific advances and technological innovations over the last four decades.

    Chung, Eric

    2017-02-01

    Despite introduction of oral phosphodiesterase type 5 inhibitors and intracavernosal vasoactive agents, penile prosthesis implant remains a relevant and desired option with sales of penile prostheses continue to stay high, as many men became refractory to medical therapy and/or seeking a more effective and permanent therapy. There are two types of penile prosthesis implants: inflatable and non-inflatable types, and the inflatable penile implants can be subdivided into single-, two- and three-piece devices. Non-inflatable penile prosthesis (non-IPP) may be referred to as semi-rigid rod or malleable prosthesis. IPP is considered a superior option to malleable prosthesis as it produces penile rigidity and flaccidity that closely replicates a normal penile erectile function. Since the introduction of IPP by Scott in 1973, surgical landscape for penile prosthesis implantation has changed dramatically. Advances in prosthesis design, device technologies and surgical techniques have made penile prosthesis implant a more natural, durable and reliable device. The following article reviews the scientific advances and technological innovation in modern penile prosthesis implants over the last four decades.

    2013-12-01

    Penile self-injection of various oils is still carried out among Eastern Europe people for penile girth augmentation despite the potential destructive complications of this practice are well known. Penile reactions to such foreign bodies include scarring, abscess formation, ulceration, and even Fournier's gangrene; voiding problems due to mineral oil self-injection have been reported only once. To our knowledge, we describe the first case of paraffin self-injection for penile girth augmentation presenting with acute urinary retention. A 27-year-old Romanian man presented with severe penile pain and acute urinary retention five years after having practiced repeated penile self-injections of paraffin for penile girth augmentation. The penile shaft was massively enlarged, fibrotic and phymotic; urethral catheterization failed due to severe stricture of the proximal pendulum urethra. The patients refused placement of a suprapubic catheter and underwent immediate penile surgical exploration. The scarred tissue between dartos and Buck's fascia and a fibrotic ring occluding the urethra were removed and the penile skin reconstructed. Pathology confirmed the diagnosis of paraffinoma. The patient resumed normal voiding immediately after catheter removal on second postoperative day; he was very pleased with cosmetic, sexual and voiding results at six weeks, six months and 1 year follow-up. The present report describes a novel complication of penile self-injection for penile girth augmentation. Because of the increasing number of patients seeking penile augmentation, physicians dealing with sexual medicine should pay more attention to such request to prevent the use of non medical treatments that can turn into medical disasters.

  7. Superficial Dorsal Venous Rupture of the Penis: False Penile Fracture That Needs to be Treated as a True Urologic Emergency.

    Truong, Hong; Ferenczi, Basil; Cleary, Ryan; Healy, Kelly A

    2016-11-01

    A 38-year-old man with history of repaired penile fracture presented with rapid detumescence, penile pain, and ecchymosis during vaginal sexual intercourse concerning for recurrent fracture. Surgical exploration revealed ruptured superficial dorsal vein of the penis, which was subsequently ligated. Patients with traumatic penile vascular injuries often present with clinical features indistinguishable from a true penile fracture. Gradual detumescence and an absence of characteristic popping sound may indicate a vascular injury but they cannot safely rule out a true penile fracture. Both true and false penile fractures require emergent surgical exploration and repair to prevent long-term complications. Copyright © 2016 Elsevier Inc. All rights reserved.

    Although penile implantation remains a final solution for patients with refractory impotence, undesirable postoperative effects, including penile size reduction and cold sensation of the glans penis, remain problematic. We report results of a surgical method designed to avoid these problems. From 2003 to 2013, 35 consecutive patients received a malleable penile implant. Of these, 15 men (the enhancing group) were also treated with venous ligation of the retrocoronal venous plexus, deep dorsal...

  14. Low-grade liquid silicone injections as a penile enhancement procedure: Is bigger better?

    Ramesh Sasidaran

    2012-01-01

    Full Text Available To report our experience with 5 cases of complications of penile enhancement procedures secondary to liquid silicone injections and our method of management of its debilitating effects. All five patients were treated with excision of penile shaft skin down to buck′s fascia followed by resurfacing with split thickness skin grafting. We conclude that penile enhancement procedures with liquid silicone by non-medical personnel could result in devastating consequences. We also demonstrate that a simple method of excision of the entire penile shaft skin and resurfacing with split skin grafting showed improvement in cosmetic as well as functional outcome.

  15. Nonsurgical Medical Penile Girth Augmentation: Experience-Based Recommendations.

    Oates, Jayson; Sharp, Gemma

    2017-10-01

    Penile augmentation is increasingly sought by men who are dissatisfied with the size and/or appearance of their penis. However, augmentation procedures are still considered to be highly controversial with no standardized recommendations reported in the medical literature and limited outcome data. Nevertheless, these procedures continue to be performed in increasing numbers in private settings. Therefore, there is a need for safe, effective, and minimally invasive procedures to be developed, evaluated, and reported in the research literature. In this article, we focus particularly on girth enhancement procedures rather than lengthening procedures as penile girth appears to be particularly important for sexual satisfaction. We discuss the advantages and disadvantages of the common techniques to date, with a focus on the minimally invasive injectable girth augmentation techniques. Based on considerable operative experience, we offer our own suggestions for patient screening, technique selection, and perioperative care. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    2005-10-01

    To test the feasibility of using the penile corpora cavernosa for blood transfusion and resuscitation purposes. Three male donkeys were used for autologous blood transfusion into the corpus cavernosum during three sessions with a 1-week interval between each. Two blood units (450 mL each) were transfused per session to each donkey. Moreover, three dogs were bled up until a state of shock was produced. The mean arterial blood pressure decreased to 60 mm Hg. The withdrawn blood (mean volume 396.3 mL) was transfused back into their corpora cavernosa under 150 mm Hg pressure. Different transfusion parameters were assessed. The Assiut faculty of medicine ethical committee approved the study before its initiation. For the donkey model, the mean time of blood collection was 12 minutes. The mean time needed to establish corporal access was 22 seconds. The mean time of blood transfusion was 14.2 minutes. The mean rate of blood transfusion was 31.7 mL/min. Mild penile elongation with or without mild penile tumescence was observed on four occasions. All penile shafts returned spontaneously to their pretransfusion state at a maximum of 5 minutes after cessation of blood transfusion. No extravasation, hematoma formation, or color changes occurred. Regarding the dog model, the mean rate of transfusion was 35.2 mL/min. All dogs were resuscitated at the end of the transfusion. The corpus cavernosum is a feasible, simple, rapid, and effective alternative route for blood transfusion and venous access. It can be resorted to whenever necessary. It is a reliable means for volume replacement and resuscitation in males.

  17. Glansectomy and Split-thickness Skin Graft for Penile Cancer.

    Penile cancer is a rare malignancy that is confined to the glans in up to four out of five cases. Although descriptions of glansectomy exist, there are no contemporary video explanations or large published single centre series. To show the efficacy and safety of glansectomy and split-thickness skin graft (STSG) reconstruction. Data were collected retrospectively for patients identified from surgical theatre diaries between February 2005 and January 2016. 177 patients with histologically proven squamous-cell carcinoma on the glans underwent glansectomy and STSG at a tertiary referral centre in the UK. The median follow-up was 41.4 mo. The skin is incised at the subcoronal level and deepened onto Buck's fascia. Dissection is performed over or under Buck's fascia, depending on suspicion of invasion or risk of disease. The glans is excised and a neoglans is created using a STSG. Local recurrence, cancer-specific survival, overall survival, and complications. Sixteen out of 172 patients (9.3%) experienced local recurrence during the follow-up period. Eighteen out of 174 (10.7%) patients died of penile cancer, while 29 patients in total died during the follow-up period. Of 145 patients, 9% required operative intervention for complications, including graft loss and meatal stenosis. Limitations include the retrospective data collection and the lack of functional and sexual outcomes. Glansectomy and STSG comprise a safe procedure in terms of oncologic control and complications for patients with penile cancer confined to the glans penis. Further studies are required to assess functional and sexual outcomes in these patients. We report on the management of penile cancers confined to the head of the penis using glansectomy and a split-thickness skin graft to recreate the appearance of a glans. This technique is safe and effective, with limited complications. Copyright © 2016. Published by Elsevier B.V.

  18. Distal corporoplasty for distal cylinders extrusion after penile prosthesis implantation.

    Carrino, Maurizio; Chiancone, Francesco; Battaglia, Gaetano; Pucci, Luigi; Fedelini, Paolo

    2017-02-03

    Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Several methods have been proposed for repairing a distal penile erosion. We present our preliminary experience in "Distal corporoplasty" technique. We enrolled 18 consecutive patients whose underwent a distal corporoplasty with simultaneous reimplantation of an "AMS 700 inflatable penile prosthesis (LGX)" from January 2013 to November 2015 at our hospital. All procedures were performed by a single surgical team. Intraoperative and postoperative complications have been classified and reported according to Satava6 and Clavien-Dindo (CD) system.7 Mean values with standard deviations (±SD) were computed and reported for all items. Mean age of the patients was 53.61 (±11.90) years. Mean body max index (BMI) was 24.22 (±2.51). Mean operative time was 85.2 (±13.1) minutes. Blood losses were minimal. No intraoperative complications are reported according to Satava classification. Four out of 18 patients (22.22%) experienced postoperative complications according to CD system. All patients had sexual intercourse for the first time postsurgery after a mean of 59.11 ± 2.08 days. Mean follow-up was 22.11 (±9.95). Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Distal corporoplasty was first described by Mulcahy. He reported a series of 14 patients with a follow-up of about 2 years with optimal functional outcomes. Moreover, distal corporoplasty resulted in shorter operative time, better function, less pain, and fewer recurrences than Gortex windsock repair.10 In our experience, distal corporoplasty is a simple and safe procedure in the treatment of distal cylinders extrusion when the prosthetic material is not exposed to the exterior.

    2016-09-01

    An unknown percentage of men will take every risk to develop a larger penis. Thus far, most injectables have caused serious problems. Polymethylmethacrylate (PMMA) microspheres have been injected as a wrinkle filler and volumizer with increasing safety since 1989. To report on a safe and permanently effective method to enhance penile girth and length with an approved dermal filler (ie, PMMA). Since 2007, the senior author has performed penile augmentation in 752 men mainly with Metacrill, a suspension of PMMA microspheres in carboxymethyl-cellulose. The data of 729 patients and 203 completed questionnaires were evaluated statistically. The overall satisfaction rate was 8.7 on a scale of 1 to 10. After one to three injection sessions, average girth increased by 3.5 cm, or 134% (10.2 to 13.7 cm = 134.31%). Penile length also increased by weight and stretching force of the implant from an average of 9.8 to 10.5 cm. Approximately half the patients perceived some irregularities of the implant, which caused no problems. Complications occurred in 0.4%, when PMMA nodules had to be surgically removed in three of the 24% of patients who had a non-circumcised penis. After 5 years of development, penile augmentation with PMMA microspheres appears to be a natural, safe, and permanently effective method. The only complication of nodule formation and other irregularities can be overcome by an improved injection technique and better postimplantation care.

    The epidemiology and pathohistogenesis of avascular femoral head necrosis has still not been clarified in detail. Because the course of the disease runs in stages and over a long time period nearly always culminates in the necessity for a total hip prosthesis, an exact radiological evaluation is of paramount importance for the treatment. There is a need for a common staging system to enable comparison of different therapy concepts and especially their long-term results. In this article the ARCO staging system is described in full detail, which includes all radiological modalities as well as histopathological alterations. (orig.) [German] Bei der avaskulaeren Femurkopfnekrose handelt es sich um ein Krankheitsbild, dessen Ursachen noch immer nicht vollstaendig geklaert sind. Da die Erkrankung stadienhaft verlaeuft und ueber einen laengeren Zeitraum betrachtet nahezu immer in einem prothetischen Hueftersatz muendet, ist eine genaue radiologische Abklaerung fuer die Behandlung von enormer Bedeutung. Um Langzeiterfolge verschiedener Therapiekonzepte vergleichen zu koennen, sind eine exakte Beschreibung und darauf basierend die Verwendung einer einheitlichen Stadieneinteilung wuenschenswert. In der vorliegenden Arbeit wird die ARCO-Stadieneinteilung im Detail beschrieben, die alle bildgebenden Methoden beruecksichtigt und histopathologische Veraenderungen mit einbezieht. (orig.)

    Purpose The aim of this study was to assess the clinicopathologic characteristics of penile cancer, including patterns of therapy, oncologic results, and survival. Materials and Methods Between January 2005 and July 2015, 71 patients at 6 institutions who had undergone penectomy or penile biopsy were enrolled. Their medical records were reviewed to identify the mode of therapy, pathology reports, and cancer-specific survival (CSS) rate. Results Clinicopathologic and outcome information was available for 52 male patients (mean age, 64.3 years; mean follow-up, 61.4 months). At presentation, 17 patients were node-positive, and 4 had metastatic disease. Management was partial penectomy in 34 patients, total penectomy in 12 patients, and chemotherapy or radiotherapy in 6 patients. The pathology reports were squamous cell carcinoma in 50 patients and other types of carcinoma in the remaining 2 patients. Kaplan-Meier survival analysis showed a 5-year CSS rate of 84.0%. In univariate and multivariate analyses, the American Joint Committee on Cancer (AJCC) stage and pathologic grade were associated with survival. Conclusions Partial penectomy was the most common treatment of penile lesions. The oncologic outcomes were good, with a 5-year CSS of 84.0%. The AJCC stage and pathologic grade were independent prognostic factors for survival. PMID:28459145

    1998-05-01

    Elevation of glycosylated hemoglobin above levels of 11.5 mg.% has been considered a contraindication to penile prosthesis implantation in diabetic patients. We determine the predictive value of glycosylated hemoglobin A1C in penile prosthesis infections in diabetic and nondiabetic patients to confirm or deny this prevalent opinion. We conducted a 2-year prospective study of 389 patients, including 114 diabetics, who underwent 3-piece penile prosthesis implantation. All patients had similar preoperative preparation without regard to diabetic status, control or glycosylated hemoglobin A1C level. Risk of infection was statistically analyzed for diabetics versus nondiabetics, glycosylated hemoglobin A1C values above and below 11.5 mg.%, insulin dependent versus oral medication diabetics, and fasting blood sugars above and below 180 mg.%. Prosthesis infections developed in 10 diabetics (8.7%) and 11 nondiabetics (4.0%). No increased infection rate was observed in diabetics with high fasting sugars or diabetics on insulin. There was no statistically significant increased infection risk with increased levels of glycosylated hemoglobin A1C among all patients or among only the diabetics. In fact, there was no meaningful difference in the median or mean level of glycosylated hemoglobin A1C in the infected and noninfected patients regardless of diabetes. Use of glycosylated hemoglobin A1C values to identify and exclude surgical candidates with increased risk of infections is not proved by this study. Elevation of fasting sugar or insulin dependence also does not increase risk of infection in diabetics undergoing prosthesis implantation.

    To evaluate the psychosexual benefit obtained from multicomponent penile implant surgery in patients with erectile dysfunction. A psychosexual questionnaire was given to 35 patients undergoing penile prosthesis implantation before surgery and at 3 months, 6 months, and 1 year after surgery. The questionnaire consisted of 13 questions scored on a scale from 1 through 5. Results of the questionnaire were statistically analyzed for differences among the preoperative, 3-month postoperative, 6-month postoperative, and 1-year postoperative period. The general linear model evaluation showed a significant difference for each overall combination of the following pairs: preoperative versus 3 months postoperative (P=0.0005) and 3 months postoperative versus 6 months postoperative (P=0.002). There was no overall difference between psychosexual total score at 6 months after surgery and 1 year after prosthesis implantation (P=0.85). The patients perceived improvement in their erectile ability and libido. Concern about obtaining and maintaining an erection during intercourse was significantly alleviated. There was an increase in the frequency of sexual activity and an improvement in satisfaction with sex life. A decrease in feelings of sadness, depression, anxiety, anger, frustration, and embarrassment related to sexual activity was also noted. The current study demonstrates significant improvement in the psychosexual well being of multicomponent penile implant recipients, with attainment of a high level of patient satisfaction up to 1 year after surgery.

  5. Surgical reimplantation of penile glans amputation in children during circumcision

    2014-01-01

    Full Text Available Circumcision is one of the oldest and most commonly performed surgical procedures. Unfortunately, various complications may occur during circumcision, ranging from trivial to tragic such as penile amputation which is a serious complication and a challenging injury to treat. We describe two cases of non-microsurgical successful reattachment of a distal penile glans which were amputated during circumcision. In the first case, a 5-year-old child underwent circumcision by an urologist under local anesthesia. In the second one, a 3-year-old child underwent circumcision by a general practitioner who used to make circumcision. In this article, the literature is reviewed; results and potential complications of this surgery are also discussed. Glans sensation was present, early morning erection was maintained, and there was an erectile response during penile manipulation in both cases. Although circumcision is not technically difficult, it should be taken seriously. The use of microsurgical reattachment is not always possible, especially in pediatric cases; it also requires special equipment and training.

    2010-01-01

    Salvage esophagectomy is the sole curative intent treatment for patients with persistent or recurrent locoregional disease after definitive chemoradiotherapy (CRT) for esophageal carcinoma. However, salvage esophagectomy is a very high-risk operation, and airway necrosis is a fatal complication. Between 1997 and 2007, 49 patients with thoracic esophageal cancer underwent salvage esophagectomy after definitive CRT. We retrospectively compared patients with and without airway necrosis, and investigated operative procedures related to airway necrosis. Airway necrosis occurred in five patients (10.2%), of four patients (80%) died during their hospitalization. Airway necrosis seemed to be closely related to operative procedures, such as resection of bronchial artery and cervical and subcarinal lymph node dissection. Bronchogastric fistula following necrosis of gastric conduit occured in 2 patients reconstructed through posterior mediastinal route. Airway necrosis is a highly lethal complication after salvage esophagectomy. It is important in salvage esophagectomy to take airway blood supply into consideration sufficiently and to reconstruct through retrosternal route to prevent bronchogastric fistula. (author)

  11. A comprehensive, prospective study of penile dimensions in Chinese men of multiple ethnicities.

    Chen, X B; Li, R X; Yang, H N; Dai, J C

    2014-01-01

    This study aimed to establish a reference range of penile length and circumference of adult males in China, and to compare the penile dimensions of different ethnical backgrounds. To do this, penile length and circumference measurements were obtained from 5196 healthy males attending the Urology Counseling Clinic. The mean value of penile dimensions was a flaccid length of 6.5 ± 0.7 cm, a stretched length of 12.9 ± 1.2 cm and a flaccid circumference of 8.0 ± 0.8 cm. In the subgroup of 311 males, the mean erectile length was 12.9 ± 1.3 cm and the mean erectile circumference was 10.5 ± 0.9 cm, the mean flaccid and erectile glans lengths were 2.7 ± 0.3 and 3.4 ± 0.4 cm, respectively, and the mean flaccid and erectile glans diameters were 2.6 ± 0.2 and 3.4 ± 0.4 cm, respectively. We found that flaccid penile length and circumference varied among different ethnicities. This study established a reference range for penile dimensions, which will help when counseling patients worried about their penile size or seeking penis enlargement surgery. We also found that penile dimensions are different in different ethnicities, but further investigations are needed to validate this.

  12. Recurrent furunculosis as a cause of isolated penile lymphedema: a case report

    2010-06-01

    Full Text Available Abstract Introduction Isolated lymphedema of the penis is extremely rare: combined involvement of the scrotum and penis is the norm. Furunculosis as a cause is not, to our knowledge, previously reported. We present a case of isolated penile lymphedema that responded to excision of lymphedematous tissue and reconstruction with flaps. Case presentation A 32-year-old Arab man presented with a three-year history of a gradually increasing, painless penile swelling. Our patient's main complaint was non-erectile sexual dysfunction. The swelling was preceded by at least three prior episodes of severe furunculosis at the penile root. He had no other contributory past medical or family history. On examination there was gross penile enlargement, maximally at the mid shaft, associated with thickened skin at the sites of prior furunculosis. The glans and scrotum were normal. Both testes were palpable. Serology for filariasis, and urinary tract ultrasound and computed tomography scan were normal. The clinical diagnosis was lymphedema following recurrent penile furunculosis. At operation the lymphedematous tissues were removed. Closure of the penile shaft was accomplished by bilateral advancement of flaps from both ends of the penis. He resumed normal sexual activity one month after surgery. At 12 months, he had a good cosmetic result, with no signs of recurrence. Conclusions Furunculosis at the penile root may result in lymphedema confined to the penile shaft, sparing the scrotum. Excision of abnormal tissue and cover with a skin flap gave excellent cosmetic results, and allowed satisfactory sexual activity.

    There is a gap in the literature about psychological status of patients following penile fracture surgery. We aimed to assess the long-term psychological status of penile fracture patients who have been treated by immediate surgical repair. A total of 32 patients with penile fracture have been treated surgically at our center. These 32 patients and 30 healthy control subjects were included in the study. All participants have completed the Hospital Anxiety and Depression Scale (HADS), Glombok-Rust Inventory of Satisfaction Scale (GRISS), and the premature ejaculation diagnostic tool (PEDT). The mean age of patients was 30.4 years and the mean body mass index was 27.3 kg m(-2). Sexual intercourse was the most common cause of the fracture. Immediate surgical repair was performed in all cases using a circumferential subcoronal incision and none of the patients had urethral injury intraoperatively. All tears were unilateral with a mean size of 1.5 cm. Only two patients had superficial dorsal vein rupture. At the day of assessment, the mean time elapsed after penile trauma was 15.9±6.3 months (range: 6-23). Only three patients had complications due to penile fracture including minimal penile curvature, penile nodule, and penile pain during intercourse. The mean scores obtained from PEDT, HADS, and GRISS did not show any statistically significant difference between groups. Anxiety, depression, premature ejaculation, and sexual dyssatisfaction levels were similar in both penile fracture patients who underwent immediate surgical repair and healthy control subjects. Immediate surgical repair of corporal ruptures have not shown any harmful psychogenic sequelae on patients with penile fracture.

    "Prospective Registry of Outcomes with Penile Prosthesis for Erectile Restoration" (PROPPER) is a large, multi-institutional, prospective clinical study to collect, analyze, and report real-world outcomes for men implanted with penile prosthetic devices. We prospectively correlated co-morbid conditions and demographic data with implanted penile prosthesis size to enable clinicians to better predict implanted penis size following penile implantation. We present many new data points for the first time in the literature and postulate that radical prostatectomy (RP) is negatively correlated with penile corporal length. Patient demographics, medical history, baseline characteristics and surgical details were compiled prospectively. Pearson correlation coefficient was generated for the correlation between demographic, etiology of ED, duration of ED, co-morbid conditions, pre-operative penile length (flaccid and stretched) and length of implanted penile prosthesis. Multivariate analysis was performed to define predictors of implanted prosthesis length. From June 2011 to June 2017, 1,135 men underwent primary implantation of penile prosthesis at a total of 11 study sites. Malleable (Spectra), 2-piece Ambicor, and 3-piece AMS 700 CX/LGX were included in the analysis. The most common patient comorbidities were CV disease (26.1%), DM (11.1%), and PD (12.4%). Primary etiology of ED: RP (27.4%), DM (20.3%), CVD (18.0%), PD (10.3%), and Priapism (1.4%), others (22.6%). Mean duration of ED is 6.2¡À4.1 years. Implant length was weakly negatively correlated with White/Caucasian (r=-0.18; Pprosthesis length is negatively correlated with some ethnic groups, prostatectomy, and incontinence. Positive correlates include CV disease, preoperative stretched penile length, and flaccid penile length.

  15. Penile Anaerobic Dysbiosis as a Risk Factor for HIV Infection

    Cindy M. Liu

    2017-07-01

    Full Text Available Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4+ T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants nested within a randomized-controlled trial of male circumcision in Rakai, Uganda. Using penile (coronal sulcus swabs collected by study personnel at trial enrollment, we characterized the penile microbiome by sequencing and real-time PCR and cytokine levels by electrochemiluminescence assays. The absolute abundances of penile anaerobes at enrollment were associated with later risk of HIV seroconversion, with a 10-fold increase in Prevotella, Dialister, Finegoldia, and Peptoniphilus increasing the odds of HIV acquisition by 54 to 63%, after controlling for other known HIV risk factors. Increased abundances of anaerobic bacteria were also correlated with increased cytokines, including interleukin-8, which can trigger an inflammatory response that recruits susceptible immune cells, suggesting a mechanism underlying the increased risk. These same anaerobic genera can be shared between heterosexual partners and are associated with increased HIV acquisition in women, pointing to anaerobic dysbiosis in the genital microbiome and an accompanying inflammatory response as a novel, independent, and transmissible risk factor for HIV infection.

  16. Isolation and identification of female DNA on postcoital penile swabs.

    2000-06-01

    After sexual assault, cells originating from the assailant may be recovered from the victim. Through polymerase chain reaction (PCR)-based technology, positive scientific identification of the assailant may be made from these cells. Described is a prospective study describing a method for positively identifying cells from a female sex partner obtained from postcoital swabs of the penis of the male sex partner. Swabs were taken from the penis of a man at 1- to 24-hour intervals after coitus. DNA was isolated from each swab through standard organic extraction methods. The presence of female DNA was detected using the gender-specific amelogenin marker. Extracted DNA was amplified for eight different genetic loci using the Promega PowerPlex kit (Promega) and Amplitaq Gold (Perkin Elmer). Amplified samples were electrophoresed on precast sequencing gels (Hitachi) and were analyzed fluorescently using Hitachi's FMBIO 2 fluorescent scanner and software. Each sample obtained from a penile swab or condom was compared to male and female buccal controls. Female DNA was isolated from all postcoital penile swabs as determined by exclusive amplification of the X-chromosome specific 212 base pair amelogenin marker. In all cases, scientific identification of the female DNA from the swabs was determined by coamplification of eight STR loci (PowerPlex) and was compared to female and male control profiles. Cells shed from a female victim during sexual intercourse can be retrieved from the penis of a male offender after sexual intercourse during a 1- to 24-hour postcoital interval. DNA can be extracted from these cells and can be used to scientifically identify the female sexual participant through PCR-based technology. It is suggested that penile swabs be taken from alleged perpetrators of sexual assaults to associate them with a female victim.

    Recently, a 22-year-old Caucasian female was referred to our Hospital two days post-partum. She had been feeling unwell during the last few days of her pregnancy and complained of multiple aches and pains, worst in the abdomen and lower back. Her admission platelet count was severely depressed and a bone biopsy showed extensive marrow necrosis with viable bony trabeculae. There was no evidence of vasculitis, vascular thrombosis, or malignancy. Widespread marrow necrosis in pregnancy followed by recovery, to our knowledge, has not been previously reported. (orig.)

    2018-06-01

    To report on our initial experience in the management of war-related penile injuries; proper diagnosis and immediate treatment of penile injuries is essential to gain satisfactory results. Besides treating primary wounds and restoring penile function, the cosmetic result is also an important issue for the surgeon. The study was conducted in the Department of Urology at Benghazi Medical Center and comprised all patients who presented with a shotgun, gunshot or explosive penile injury between February 2011 and August 2017. The patient's age, cause of injury, site and severity of injuries, management, postoperative complications, and hospital stay, were recorded. In all, 29 males with war-related penile injuries were enrolled in the study. The mean (SD) age of these patients was 31.3 (10.5) years. The glans, urethra, and corporal bodies were involved in four (13.7%), 10 (34.4%), and 20 (68.9%) of the patients, respectively. According to the American Association for the Surgery of Trauma Penis Injury Scale, Grade III penile injuries were the most common (11 patients, 37.9%). The most common post-intervention complications were urethral stricture with or without proximal urethrocutaneous fistula (eight patients, 27.5%), followed by permanent erectile dysfunction (five patients, 17.2%). In patients who sustain war-related penile injuries the surgeon's efforts should not only be directed to restoring normal voiding and erectile function but also on the cosmetic appearance of the penis.

  19. Adjuvant Maneuvers for Residual Curvature Correction During Penile Prosthesis Implantation in Men with Peyronie's Disease.

    Berookhim, Boback M; Karpman, Edward; Carrion, Rafael

    2015-11-01

    The surgical treatment of comorbid erectile dysfunction and Peyronie's disease has long included the implantation of an inflatable penile prosthesis as well as a number of adjuvant maneuvers to address residual curvature after prosthesis placement. To review the various surgical options for addressing curvature after prosthesis placement, with specific attention paid to an original article by Wilson et al. reporting on modeling over a penile prosthesis for the management of Peyronie's disease. A literature review was performed analyzing articles reporting the management of penile curvature in patients undergoing implantation of an inflatable penile prosthesis. Reported improvement in Peyronie's deformity as well as the complication rate associated with the various surgical techniques described. Modeling is a well-established treatment modality among patients with Peyronie's disease undergoing penile prosthesis implantation. A variety of other adjuvant maneuvers to address residual curvature when modeling alone is insufficient has been presented in the literature. Over 20 years of experience with modeling over a penile prosthesis have proven the efficacy and safety of this treatment option, providing the surgeon a simple initial step for the management of residual curvature after penile implantation which allows for the use of additional adjuvant maneuvers in those with significant deformities. © 2015 International Society for Sexual Medicine.

  20. Malignant priapism: Penile metastasis originating on a primary prostate adenocarcinoma

    Sandro Roberto da Silva Gaspar

    2015-01-01

    Full Text Available Malignant priapism is a definition invented in 1938 by Peacock, defined as a persistent erection, not related with sexual activity, caused by cavernous sinus and associated venous systems invasion with malignant cells. Penile secondary lesions are rare entities. Primary locations are usually the pelvic cavity organs, namely the prostate and the bladder as the most common ones. Priapism as a first manifestation of these kinds of lesions is even rarer. The aim was to present a 52-year-old patient harboring a penile metastasis that originated in the primary prostate adenocarcinoma, manifesting itself as a "common" priapism. The patient referred to the emergency room presenting with a priapism and nodules at the coronal sulcus, without previous similar episodes. His evolution until properly diagnosed was catastrophic with multiple lymph nodes, bone and organ involvement, and with his demise soon after from serious bleeding and congestive heart failure, almost 2 months after he first came to the emergency room. We review the literature concerning malignant priapism, diagnosis, and current treatment and survival perspectives.

  1. Diagnosing erectile dysfunction: the penile dynamic colour duplex ultrasound revisited.

    Aversa, A; Bruzziches, R; Spera, G

    2005-12-01

    A number of disease processes of the penis including Peyronie's disease, priapism, penile fractures and tumors are clearly visualized with ultrasound. Diagnostic evaluation of erectile dysfunction (ED) by penile dynamic colour-duplex Doppler ultrasonography (D-CDDU) is actually considered a second level approach to ED patients because of the fact that intracavernous injections test IV with prostaglandin-E(1) may provide important information about the patients' erectile capacity. However, no direct vascular imaging and a high percentage of false negative diagnoses of vasculogenic ED are its major pitfalls and subsequent treatment decisions remain quite limited. The occurrence of ED and its sentinel relationship to cardiovascular disease has prompted more accurate vascular screening in all patients even in the absence of cardiovascular risk factors. The sonographic evaluation of the intima-media thickness of the carotid arteries may sometimes represent an early manifestation of diffuse atherosclerotic disease and endothelial damage. This latter finding is often the cause of failure to oral agents, i.e. phosphodiesterase inhibitors, because of inability of the dysfunctional endothelium to release nitric oxide. D-CDDU represents an accurate tool to investigate cavernous artery inflow and venous leakage when compared with more invasive diagnostic techniques i.e. selective arteriography and dynamic infusion cavernosometry along with cavernosography.

  2. Penile involvement in Systemic Sclerosis: New Diagnostic and Therapeutic Aspects

    Antonio Aversa

    2010-01-01

    Full Text Available Systemic Sclerosis (SSc is a connective tissue disorder featuring vascular alterations and an immunological activation leading to a progressive and widespread fibrosis of several organs such as the skin, lung, gastrointestinal tract, heart, and kidney. Men with SSc are at increased risk of developing erectile dysfunction (ED because of the evolution of early microvascular tissutal damage into corporeal fibrosis. The entity of penile vascular damage in SSc patients has been demonstrated by using Duplex ultrasonography and functional infra-red imaging and it is now clear that this is a true clinical entity invariably occurring irrespective of age and disease duration and constituting the ‘‘sclerodermic penis’’. Once-daily phosphodiesterase type-5 (PDE5 inhibitors improve both sexual function and vascular measures of cavernous arteries by improving surrogate markers of endothelial dysfunction, that is, plasma endothelin-1 and adrenomedullin levels, which may play a potential role in preventing progression of penile fibrosis and ED. Also, the beneficial effect of long-term PDE5i add-on therapy to SSc therapy in the treatment of Raynaud's phenomenon is described.

  3. MRI of penile fracture: diagnosis and therapeutic follow-up

    Uder, Michael; Gohl, Dietrich; Takahashi, Masahide; Kramann, Bernhard; Schneider, Guenther

    2002-01-01

    A rupture of corpus cavernosum (CC) is a rare injury of the erect penis. The present study describes the role of MRI for diagnosis and follow-up of this injury. Four patients with clinically suspected acute penile fractures underwent MRI. Imaging findings were confirmed at surgery. In three patients, follow-up MRI was also available at 1, 6 and 16 weeks after surgical repair. In all patients pre-contrast T1-weighted images (T1WI) clearly disclosed ruptures of CC, which depicted as discontinuity of low signal intensity of the tunica albuginea (TA). Concomitant subcutaneous haematoma were well visualised both on T1-weighted (T1WI) and T2-weighted images, whereas haematoma in CC were optimally demonstrated on contrast-enhanced T1WI. On follow-up MRI all fractures presented similar healing process. Shortly after the repair, the tunical suture showed an increase in signal intensity on pre-contrast T1WI and was strongly enhanced with the administration of contrast material. Then the tear site gradually recovered low signal intensity on all spin-echo sequences by 4 months after surgery. These serial findings may suggest the formation of vascularised granulation tissue during cicatrisation. Magnetic resonance imaging is of great value for the diagnosis and follow-up in patients with penile fracture. (orig.)

  4. Utilization of penile prosthesis and male incontinence prosthetics in Saudi Arabia.

    Alwaal, Amjad; Al-Sayyad, Ahmad J

    2017-01-01

    Erectile dysfunction is a prevalent disease affecting over 50% of men between the ages of 40 and 70 years. Penile prosthesis represents the end of the line treatment when other less invasive therapies fail or are contraindicated. Male stress urinary incontinence can significantly diminish quality of life and lead to embarrassment and social withdrawal. Surgical therapies, such as male urethral slings and artificial urinary sphincters (AUS), are considered effective and safe treatments for male stress incontinence. No data exist on the utilization of penile prosthesis or male incontinence surgical treatment in Saudi Arabia. Generally, urological prosthetic surgery is performed either in private hospitals or in government hospitals. Our aim was to assess the trend of penile prosthesis and male incontinence device utilization in Saudi Arabia. We utilized sales' data of penile prosthetics, male slings, and AUS from the only two companies selling these devices in Saudi Arabia (AMS ® and Coloplast ® ), from January 2013 to December 2016. There were 2599 penile prosthesis implantation procedures done in the study period, with 67% of them performed in private institutions. There was a progressively increased use of penile prosthetics which nearly doubled from 2013 to 2016. The main type of prosthesis utilized was the semirigid type 70% versus 11% of the 2-piece inflatable and 17% of the 3-piece inflatable device. Only 10 slings and 31 AUS were inserted during the same study period. There is an increased utilization of penile prosthetics in Saudi Arabia. The private sector performs the majority of penile prosthesis procedures, and most of them are of the semirigid type. The governmental sector is more likely to perform inflatable penile prosthesis and male incontinence device procedures. Male incontinence prosthetics' use is very limited in Saudi Arabia.

  5. Severe congenital penile torsion with anterior urethral diverticulum: A case report

    2018-03-01

    Full Text Available Introduction: We present a rare case of severe penile torsion of 180° along with giant congenital anterior urethral diverticula. Presentation of these two rare anomalies together is extremely rare and has not been reported yet. The extreme rarity of the case and its management warrants this presentation. Observation: A 5 years old boy presented to us as a case of epispadias with post-void dribbling and wetting of the underwears. On examination, he was found to be a case of severe congenital penile torsion with diversion and rotation of median raphae in a counterclockwise fashion upto the midline dorsally confirming 180° torsion. During voiding, there was appearance of a swelling in distal penile region with passage of urinary drops while compressing it. Micturating cystourethrogram showed diverticula in penile and bulbar urethra. Torsion was completely corrected by penile de-gloving in a plane between two layers of buck fascia and mobilization of the urethra along with spongiosum proximally upto the penoscrotal junction and distally upto the glans. Diverticula was laid open and underwent urethroplasty along with double breasting of thickened diverticular tissue. Torsion was completely corrected after surgery. Post-operative recovery was uneventful. Urine culture was sterile and uroflowmetry showed maximal urinary flow of 12 ml/s at 3 months postoperatively. Conclusions: Penile de-gloving and adequate urethral mobilization corrects the severe penile torsion of 180°. Correction of severe torsion and urethroplasty is feasible in a single stage with good results.

  7. A Domino Effect? The Spread of Implantation of Penile Foreign Bodies in the Prison System

    Ryan Malloy Flynn

    2014-03-01

    Full Text Available Subcutaneous penile insertion of foreign bodies is a practice performed globally but has mostly been reported outside of the United States. An incarcerated 29-year-old Caucasian male in a midwestern prison whittled a domino into a dog bone shape and placed it into his ventral penile subcutaneous tissue. He presented to our facility with erosion of the corners of the foreign body through his skin without evidence of infection. Self-insertion of foreign bodies into penile subcutaneous tissue by incarcerated American men for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation.

  8. Development of delayed radiation necrosis

    Ohara, ShigFeki; Takagi, Terumasa; Shibata, Taichiro; Nagai, Hajime.

    1983-01-01

    The authors discussed the developing process of delayed radiation necrosis of the brain from the case of a 42-year-old female who developed intracranial hypertension and left hemiparesis 5 and a half years after radiotherapy for pituitary adenoma. The initial sign of radiation necrosis was from a CT scan taken 3 and a half years after radiotherapy showing an irregular low density lesion in the right temporal lobe. CT scan 2 years later demonstrated displacement of the midline structures to the left and a larger low density lesion with partially high density in the right MCA territory that was enhanced with intravenous contrast medium. Recovery after a right temporal lobectomy and administration of steroid hormone were uneventful. Eight months later there were no signs of raised intracranial pressure nor of neurological deficits. Tissues obtained from the right temporal lobe at lobectomy revealed the characteristic changes of delayed radiation necrosis; a mixture of fresh, recent, and old vascular lesions in the same specimen. From these findings, it was speculated that delayed radiation necrosis might initially occur within several years after radiotherapy and might gradually take a progressive and extended course, even in cases whose clinical symptoms develop much later.

  10. Reinnervating the penis in spina bifida patients in the United States: ilioinguinal-to-dorsal-penile neurorrhaphy in two cases.

    Jacobs, Micah A; Avellino, Anthony M; Shurtleff, David; Lendvay, Thomas S

    2013-10-01

    Penile sensation is absent in some patients with myelomeningocele owing to the dysfunction of the pudendal nerve. Here, we describe the introduction of penile sensation via ilioinguinal-to-dorsal-penile neurorrhaphy in two patients with penile anesthesia due to neural tube defects. To establish penile sensation via ilioinguinal-to-dorsal-penile-nerve neurorrhaphy. A 20-year-old and a 35-year-old male with L5/S1 myelomeningocele were both highly functioning and ambulatory, with intact ilioinguinal nerve distribution sensation but anesthesia of the penis and glans. They were sexually active and able to ejaculate antegrade. Both had high International Index of Erectile Function scores for confidence to achieve erection sufficient for intercourse. An incision was made from anterior superior iliac crest to the glans penis to expose the inguinal canal and ilioinguinal nerve. The ilioinguinal and dorsal penile nerve were transected and anastomosed. The anastomotic site was then wrapped in a hemostatic agent and a drain was left in place. For penile rehabilitation, both patients were instructed to stimulate the penis while looking at the genitalia to encourage redistribution of perceived sensation. Presence of erogenous penile sensation was tested by neurologic examination and patient feedback, and patients completed sexual health questionnaires. Both patients reported paresthesias of the groin with penile stimulation 1 month after surgery. Both patients are now 24 months postoperative and have erogenous sensation on the ipsilateral glans and shaft during intercourse. Neither patient has difficulty achieving or maintaining erections. We present two patients with dorsal penile reinnervation via the ilioinguinal nerve. Although nerve reinnervation has been used in urological procedures, this is the first description of an attempt to resupply penile sensation via the dorsal penile nerve in the United States with a minimum of 18 months follow-up. Early follow-up suggests

  11. Comparison of oxidative/antioxidative status of penile corpus cavernosum blood and peripheral venous blood.

    Yeni, E; Gulum, M; Selek, S; Erel, O; Unal, D; Verit, A; Savas, M

    2005-01-01

    The aim of the study is to determine and to compare the oxidative and antioxidative status of penile corpus cavernosum and peripheral venous blood. A total of 28 adult healthy males were included in the study. Whole blood was simultaneously withdrawn from penile corpus cavernosum and the cubital vein and their plasma separated. Total antioxidant capacity (TAC), vitamin C, total protein, albumin, uric acid, bilirubin and total peroxide (TP) levels of both plasma samples were measured and compared. While TAC, total protein, albumin, bilirubin and uric acid levels were higher, vitamin C levels were lower in cavernosal blood than that of peripheral blood. On the other hand, TP level was found to be higher in penile blood samples than that of peripheral blood. We thought that the normal erectile process of the penile cavernosal body leads to increased production of oxidants as in the mechanism of ischaemia-reperfusion; however, the increase of TAC can prevent development of oxidative injury.

  13. Pulsed and Color Doppler Sonographic Findings of Penile Mondor' Disease

    Han, Hye Yeon; Chung, Dong Jin; Kim, Kum Won; Hwang, Cheol Mog [University of Konyang School of Medicine, Daejeon (Korea, Republic of)

    2008-04-15

    Penile Mondor's disease is a rare disease that's characterized by thrombosis in the dorsal vein of the penis. Doppler ultrasonography (US) clearly visualizes dorsal vein thrombosis and the associated hemodynamic alterations. Previous studies have demonstrated the typical color Doppler US findings of superficial dorsal vein thrombosis without the flow signals in this area, yet this is insufficient to understand the hemodynamics in penile Mondor's disease. We report here for the first time a cavernosal artery flow signal pattern in a penile Mondor's disease patient, in addition to its previously reported classic US findings. In conclusion, the Doppler US findings of thrombus without blood flow in the superficial dorsal vein and the low-flow, high resistance in the cavernosal artery may be suggestive of penile Mondor's disease.

  16. Reference standard of penile size and prevalence of buried penis in Japanese newborn male infants.

    Matsuo, Nobutake; Ishii, Tomohiro; Takayama, John I; Miwa, Masayuki; Hasegawa, Tomonobu

    2014-01-01

    The present study set forth the reference values for penile size and determined the prevalence of buried penis in Japanese full-term newborns. The stretched penile length was measured and the presence of buried penis was assessed at 1-7 days of age in 547 Japanese full-term newborn infants born between 2008 and 2012 in Tokyo. The stretched penile lengths were compared at 1-12 hours and 1-7 days of age in 63 infants and by two observers in 73 infants to estimate postnatal changes and interobserver variation, respectively. The mean stretched penile length was 3.06 cm (SD, 0.26; 95% confidence interval [CI], 3.04-3.08) and the mean ratio of penile length to body length was 6.24 × 100(-1) (SD, 0.55 × 100(-1)), both of which were significantly smaller than those in Caucasian newborn infants. Buried penis was identified in 20 of 547 infants (3.7%; 95% CI, 2.1-5.2%). The first measurements of penile length at 1-12 hours were significantly smaller than the next measurements at 1-7 days (95% CI of the difference, 0.22-0.34). The 95% CI for the limits of agreement in the penile lengths measured by the two observers was -0.58 to -0.40 for the lower limit and 0.33 to 0.51 for the upper limit. These findings indicate that the penile length should be assessed after 24 hours of age by the reference standard of the same ethnicity for identifying micropenis and that buried penis is not uncommon in Japanese full-term newborns.

  17. Ex Vivo Model of Human Penile Transplantation and Rejection: Implications for Erectile Tissue Physiology.

    Penile transplantation is a potential treatment option for severe penile tissue loss. Models of human penile rejection are lacking. Evaluate effects of rejection and immunosuppression on cavernous tissue using a novel ex vivo mixed lymphocyte reaction (MLR) model. Cavernous tissue and peripheral blood mononuclear cells (PBMCs) from 10 patients undergoing penile prosthesis operations and PBMCs from a healthy volunteer were obtained. Ex vivo MLRs were prepared by culturing cavernous tissue for 48h in media alone, in media with autologous PBMCs, or in media with allogenic PBMCs to simulate control, autotransplant, and allogenic transplant conditions with or without 1μM cyclosporine A (CsA) or 20nM tacrolimus (FK506) treatment. Rejection was characterized by PBMC flow cytometry and gene expression transplant array. Cavernous tissues were evaluated by histomorphology and myography to assess contraction and relaxation. Data were analyzed using two-way analysis of variance and unpaired Student t test. Flow cytometry and tissue array demonstrated allogenic PBMC activation consistent with rejection. Rejection impaired cavernous tissue physiology and was associated with cellular infiltration and apoptosis. CsA prevented rejection but did not improve tissue relaxation. CsA treatment impaired relaxation in tissues cultured without PBMCs compared with media and FK506. Study limitations included the use of penile tissue with erectile dysfunction and lack of cross-matching data. This model could be used to investigate the effects of penile rejection and immunosuppression. Additional studies are needed to optimize immunosuppression to prevent rejection and maximize corporal tissue physiology. This report describes a novel ex vivo model of human penile transplantation rejection. Tissue rejection impaired erectile tissue physiology. This report suggests that cyclosporin A might hinder corporal physiology and that other immunosuppressant agents, such as FK506, might be better suited

  1. Dorsal Phalloplasty to Preserve Penis Length after Penile Prosthesis Implantation

    Osama Shaeer

    2017-03-01

    Full Text Available Objectives: Following penile prosthesis implantation (PPI, patients may complain of a decrease in visible penis length. A dorsal phalloplasty defines the penopubic junction by tacking pubic skin to the pubis, revealing the base of the penis. This study aimed to evaluate the efficacy of a dorsal phalloplasty in increasing the visible penis length following PPI. Methods: An inflatable penile prosthesis was implanted in 13 patients with severe erectile dysfunction (ED at the Kamal Shaeer Hospital, Cairo, Egypt, from January 2013 to May 2014. During the surgery, nonabsorbable tacking sutures were used to pin the pubic skin to the pubis through the same penoscrotal incision. Intraoperative penis length was measured before and after the dorsal phalloplasty. Overall patient satisfaction was measured on a 5-point rating scale and patients were requested to subjectively compare their postoperative penis length with memories of their penis length before the onset of ED. Results: Intraoperatively, the dorsal phalloplasty increased the visible length of the erect penis by an average of 25.6%. The average length before and after tacking was 10.2 ± 2.9 cm and 13.7 ± 2.8 cm, respectively (P <0.002. Postoperatively, seven patients (53.8% reported a longer penis, five patients (38.5% reported no change in length and one patient (7.7% reported a slightly shorter penis. The mean overall patient satisfaction score was 4.9 ± 0.3. None of the patients developed postoperative complications. Conclusion: A dorsal phalloplasty during PPI is an effective method of increasing visible penis length, therefore minimising the impression of a shorter penis after implantation.

  2. Tubing erosion of an inflatable penile prosthesis long after implantation.

    Morales, Alvaro

    2014-06-01

    Erosion through skin of connecting tubing of an inflatable penile prosthesis (IPP) has not been previously reported. The aim of this study was to present a case of tubing erosion, review the pertinent literature, and discuss the possible causes and management options, including preservation of the device and its components. A 42-year-old male failing to respond to medical treatment for erectile dysfunction underwent insertion of an AMS 700 IPP in 1986. Six years later, a revision was necessary because of a leak in the right cylinder and 4 years after, the pump was replaced. Fourteen years after the original implant, he presented with a portion of the tube connecting the pump to the right cylinder eroding through the skin. There was no infection. The skin area involved was resected and the original pump and tubing were buried in a new scrotal pocket after thorough irrigation. The IPP remained in place, allowing vaginal penetration and without infection for another 11 years. Three years later, it was de-functionalized, converted into a fixed volume device. It eventually was replaced 25 years after originally implanted with a semirigid prosthesis because it did not provide sufficient rigidity and because of concerns about the presence of "screws" detected during pelvic imaging. Mechanical failures in the early IPP models, as illustrated in this case, were expected. However, the long survival of the device is remarkable. Erosion of the connecting tubing through the skin is unique and, under exceptional circumstances, may be managed conservatively without replacing components of the IPP. Clinicians unfamiliar with procedures involving inflatable devices need to be aware of "foreign bodies" visible in radiological examinations in men who have had revisions of an IPP. Morales A.

    1999-08-01

    Five cases of penile metastases are presented. Axial and sagittal T1-weighted and T2-weighted scans were performed in all patients. In some, coronal images were also obtained. The penile metastases were most often seen as discrete masses in the corpora cavernosa or corpus spongiosum. An atypical pattern of diffuse infiltration is also illustrated. Limitations of cavernosography, ultrasound (US) and computed tomography (CT) are discussed. The magnetic resonance (MR) features of penile metastases and possible role MR may have in the management of these patients are described. Metastatic deposits in the penis are uncommon. First described by Eberth in 1870 in a patient with a primary rectal carcinoma, there have since been over 300 cases reported in the literature. The imaging of penile metastases is, however, less clearly defined. Until now, cavernosography, ultrasound (US) and computed tomography (CT) have been used. These techniques have limitations. Only recently has magnetic resonance imaging (MRI) been employed. We describe five cases of penile metastases evaluated with MRI and discuss the role and features of penile metastases on MRI.

    2012-05-01

    To investigate the effect of autologous dermal-fat strip grafting in penile augmentation and elongation. From May 2004 to December 2010, 24 patients underwent penile enhancement with free dermal-fat strip grafting. Through suprapubic incision, the superior suspensory ligament and part deep suspensory ligament are cutted off to lengthen the penis. The resulted dead space is filled with the autologous dermal-fat strip (6.0-9.5 cm in length, 1.2-1.5 cm in width and 0.6-0.8 cm in depth) to enhance the penis. Primary healing was achieved in 23 cases. Incisional fat liquefaction happened in one case which healed after dressing change. The penile appearance was satisfactory both at rest or erection. The penile length and circumference increased by 2.5-4.8 cm (average, 3.2 cm) and 1.8-3.0 cm (average, 2.4 cm), respectively. 18 patients were followed up for 3 months to 5 years. All the patients were satisfactory on the cosmetic and functional results. No complication happened. It is safe and effective for penile augmention and elongation with autologous dermal-fat strip grafting and disconnection of penile suspensory ligament.

  6. Why Are Men Satisfied or Dissatisfied with Penile Implants? A Mixed Method Study on Satisfaction with Penile Prosthesis Implantation.

    Carvalheira, Ana; Santana, Rita; Pereira, Nuno M

    2015-12-01

    Studies have demonstrated high levels of satisfaction with penile prosthesis implantation (PPI). However, qualitative research exploring the experience of PPI through men's narratives is scarce. The main goals were to analyze (i) the level of sexual satisfaction (quantitatively), and (ii) the reasons for satisfaction and/or dissatisfaction with PPI (qualitatively). Participants were 47 men with erectile dysfunction who underwent surgery between 2003 and 2012, placed by a single surgeon. Structured telephone interviews were carried out. Satisfaction with PPI was a qualitative and quantitative measure assessed through the following four items: (i) "Would you repeat the PPI surgery?"; (ii) "Would you recommend the PPI surgery?"; (iii) "How satisfied are you with the PP?"; and (iv) "Could you explain the motives of your satisfaction/dissatisfaction?". The majority of men (79%) reported to be satisfied with PPI. Content analysis revealed four main themes for men's satisfaction with the PPI: (i) psychological factors were reported 54 times (n = 54) and included positive emotions, self-esteem, confidence, enhancement of male identity, major live change, and self-image; (ii) improvement of sexual function was reported 54 times (n = 54) and referred to achievement of vaginal penetration, increase of sexual desire, sexual satisfaction, penis size, and improvement of erectile function; (iii) relationship factors were reported 11 times (n = 11) and referred to relationship improvement and the possibility of giving pleasure to the partner; and (iv) improvement in urinary function (n = 3). The level of satisfaction with the implementation of penile prostheses is very high, therefore constituting a treatment for erectile dysfunction with a positive impact on the experience of men at sexual, psychological and relational level. © 2015 International Society for Sexual Medicine.

  7. Pathological investigation of radiation necrosis

    Nakamura, Nishio; Yoshimura, Noriaki; Ikuta, Fusahiro

    1975-01-01

    The brain and spinal cord of an 18-year-old male, who suffered from cerebellar medulloblastoma with subarachnoid spread, had been irradiated by a large amount of Linac X-ray: 14,450 rads to the lower thoracic segments and 7,400 rads to the lumbar segments. The tumor at the roof of the 4th ventricle had disseminated along the ventricular system but was limited to the subarachnoid space of the cervical spinal cord. No remarkable changes were found in the volume or consistency of the thoracic and lumbar cord. Elasticity of the lower thoracic segment was greatly diminished and the cut surfaces were yellowish white and fragile. Microscopically extensive coagulation necrosis was observed with complete disintegration of myelin and axon. Vascular changes were most prominent in the smaller vessels, eg. hyalinous thickening, concentric cleavage, adventitial fibrosis and edema of small artery perivascular spaces, fibrin thrombi occulusion of arterioles and capillaries, and telangiectasia. In the lumbar spinal cord, moderate neuronal degeneration and protoplasmic astrocytosis were observed. Changes in the lumbar posterior white column were considered to be not only secondary degeneration but also a primary lesion caused by irradiation. Liquefactive necrosis in the gray matter of the cervical cord was thought to be a nonspecific circulatory disturbance because of the absence of vascular changes. Vascular changes were thought to be very important in the histological diagnosis of radiation myelopathy and it was supposed that increased permeability of the vessel walls was a factor in coagulation necrosis. They considered this case to have typical histology of radiation myelopathy. (Evans, J.)

  8. Prevalence of human papillomavirus and Epstein-Barr virus DNA in penile cancer cases from Brazil

    Larissa Alves Afonso

    2012-02-01

    Full Text Available Penile cancer is a potentially mutilating disease. Although its occurrence is relatively rare worldwide, penile cancer rates can be high in developing countries. A few studies have been conducted on the involvement of human papillomavirus (HPV in penile carcinoma, which have found HPV present in 30-70% of penile malignant lesions, with a higher prevalence of HPV 16 and 18. It has been assumed that cofactors, such as Epstein-Barr virus (EBV infections, may play a role in the progression of penile neoplasia. The aim of this study was to determine HPV and EBV prevalence in 135 penile malignant lesions from Brazilian men through the use of MY09/11 polymerase chain reaction (PCR, type-specific PCR and restriction fragment length polymorphism analysis. HPV prevalence among the men tested was 60.7%. Of the men who tested positive, 27 presented with HPV 16 (29.7%, five with HPV 18 (5.5%, 21 with HPV 45 (23.1% and nine with HPV 6 (9.9%. Seven mixed infections were detected (9.2%, while 11 cases remained untyped (13.4%. Regarding EBV positivity, 46.7% of the samples contained EBV DNA with EBV-1 as the most prevalent type (74.6%. More than 23% of the men were co-infected with both HPV and EBV, while 35% presented exclusively with HPV DNA and 20% presented only with EBV DNA. Penile carcinoma aetiology has not been fully elucidated and the role of HPV and EBV infections individually or synergistically is still controversial. Hence, more studies are needed to determine their possible role in carcinogenesis.

  9. Distinguishing Failure to Cure From Complication After Penile Prosthesis Implantation.

    Pineda, Miguel; Burnett, Arthur L

    2017-05-01

    A successful penile prosthesis implantation (PPI) surgery can be defined by outcomes beyond the absence of complications. To introduce the concept of failure to cure (FTC) in the context of PPI to more accurately gauge postoperative outcomes after PPI. Consecutive patients from our sexual function registry who underwent PPI from January 2011 to December 2013 were analyzed. Demographics, previous treatment of erectile dysfunction, comorbidities, social history, postoperative problems (POPs), and surgical outcomes were tabulated. Patients completed the International Index of Erection Function (IIEF) and the Erectile Dysfunction Inventory of Treatment Satisfaction questionnaires. We defined a complication, according to the Clavien-Dindo classification, as any deviation from the ideal postoperative course that is not inherent in the procedure and does not constitute an FTC. FTC was defined as a POP that was not a complication. The χ 2 tests, t-tests, or Wilcoxon rank-sum tests were used. Patient-reported and objective outcomes after PPI. Our enrollment consisted of 185 patients, and we contacted 124 (67%). Of these, 16 (12.9%) had a POP requiring reoperation. Eight patients developed surgical complications (three infections, four erosions, and one chronic pain). Eight patients had FTC (four malpositions and four malfunctions). Factors that correlated with POPs were previous PPI, body mass index higher than 30 kg/m 2 , and previous treatment with intracorporal injections (P .05 for all comparisons). POPs after PPI surgery can be more accurately categorized using the Clavien-Dindo classification of surgical complications to more clearly distinguish surgical complications from FTC. Limitations of our study include its retrospective approach. Our series included a large proportion of patients treated for prostate cancer, which limits the generalizability of our findings.

    T1-weighted (repetition time [TR] = 450 msec, echo time [TE] = 20 msec), T2-weighted (TR = 1,800 msec, TE = 20 and 80 msec), and T2*-weighted gradient-echo gradient recalled acquisition in a steady state, TR = 70 msec, TE = 30 msec, theta = 15 0 ) MR images (General Electric Signa, 1.5 T) were generated in 11 patients with avascular necrosis of the hip. Three-dimensional MR image reconstruction was performed on an independent imaging system (IIS, Dimensional Medicine Inc). Pelvic and femoral bone contours were computed based on either the T1-weighted or the T2*-weighted images. Three-dimensional displays of necrotic zones and areas of granulation tissue were computed on the basis of the T2-weighted images. The tissues were simultaneously displayed in the three-dimensional images using different colors and transparencies. The three-dimensional MR images generated demonstrated the extent of the necrotic zone and adjacent granulation tissue and their position relative to the weight-bearing surface. They may soon prove to be useful in preoperative planning and intraoperative localization of complex surgical interventions in avascular necrosis of the hip

  11. A Case Series of Patients Who Underwent Laparoscopic Extraperitoneal Radical Prostatectomy with the Simultaneous Implant of a Penile Prosthesis: Focus on Penile Length Preservation

    2018-01-01

    Purpose There are many grey areas in the field of penile rehabilitation after radical prostatectomy (RP). The preservation of the full dimensions of the penis is an important consideration for improving patients' compliance for the treatment. We present the first case series of patients treated by laparoscopic extraperitoneal RP and simultaneous penile prosthesis implantation (PPI) in order to preserve the full length of the penis and to improve patients' satisfaction. Materials and Methods From June 2013 to June 2014, 10 patients underwent simultaneous PPI (with an AMS InhibiZone prosthesis) and RP. Patients were evaluated by means of urological visits, questionnaires, and objective measurements before surgery, at discharge from the hospital, on postoperative days 21 to 28, each 3 months for the first year, and each 6 months thereafter. The main outcome measures were biochemical recurrence-free rate, penile length, and quality of life. Results Ten patients (mean age of 61 years; completed the study follow-up period (median, 32.2 months). No difference was found between the time of surgery and the 2-year follow-up evaluation in terms of penile length. The pre-surgery 36-Item Short Form Health Survey (SF-36) median score was 97. Patients were satisfied with their penile implants, and couples' level of sexual satisfaction was rated median 8. The median postoperative SF-36 score was 99 at 3 months follow-up. Conclusions Laparoscopic extraperitoneal RP surgery with simultaneous PPI placement seems to be an interesting possibility to propose to motivated patients for preserving the length of the penis and improving their satisfaction.

    2018-02-01

    To assess the postpubertal outcome of ventral penile curvature repaired in infancy in terms of recurrence and aesthetics. Postpubertal patients treated for hypospadias and ventral penile curvature in infancy at a tertiary medical center were invited to undergo assessment of the quality of the repair. Findings were compared between patients with a straight penis after skin release and patients who required dorsal plication. The cohort included 27 patients of mean age 16.5 years who were reported with straight penis after surgery. Postpubertal curvature was found in 6 of 14 patients (43%) successfully treated by skin release and 10 of 13 patients (77%) who underwent dorsal plication (P = .087). Significant curvature (≥30 degrees) was found in 1 of 14 patients in the skin-release group and 4 of 13 in the dorsal plication group (P = .16). Rates of redo urethroplasty were 2 of 14 (14%) and 5 of 10 (50%), respectively. Patient satisfaction with the appearance of the penis did not differ significantly. Ventral penile curvature repaired in infancy often recurs after puberty. The need for dorsal plication has a trend-level association with recurrence of penile curvature in puberty. It might also be related to the degree of postpubertal penile curvature and the need for redo urethroplasty. Procedure type does not affect patient satisfaction with the postpubertal appearance of the penis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Penile and preputial neoplasia in horses occurs infrequently and represents diagnostic and therapeutic challenges. The present study was carried out on a total number of 21 equids (14 stallions and 7 donkeys suffered from different penile and preputial neoplasia. Diagnosis of neoplasms was based up on history of the case, clinical examination as well as histopathological evaluation. Animals with penile and preputial neoplasms were underwent local excision and partial phallectomy with a slightly modified version of the techniques described by William’s. The diagnosed neoplasms were penile and preputial squamous cell carcinomas (SCCs; ; sarcoid (; a-fibrosarcoma; and a melanoma. Local excision was curative in all cases except 5 stallions with SCCs. These stallions had extensive damage of the glans penis, free part of the penis and the inner lamina of the internal fold of the prepuce, and they underwent a partial phallectomy with successful outcome. Follow-up information was obtained by visit and telephone inquiries. In conclusion, penile and preputial neoplasms are commonly encountered in elderly male horses and SCCs are the most common type affecting male external genitalia. Partial phallectomy is effective for management of equine neoplasia if they are confined to the glans and body of the penis and there is no proximal spread or involvement to regional lymph nodes.

  14. Contemporary management of patients with penile cancer and lymph node metastasis.

    Penile cancer is a rare disease that causes considerable physical and psychological patient morbidity, especially at advanced stages. Patients with low-stage nodal metastasis can achieve durable survival with surgery alone, but those with extensive locoregional metastasis have overall low survival. Contemporary management strategies for lymph node involvement in penile cancer aim to minimize the morbidity associated with traditional radical inguinal lymphadenectomy through appropriate risk stratification while optimizing oncological outcomes. Modified (or superficial) inguinal lymph node dissection and dynamic sentinel lymph node biopsy are diagnostic modalities that have been recommended in patients with high-risk primary penile tumours and nonpalpable inguinal lymph nodes. In addition, advances in minimally invasive and robot-assisted lymphadenectomy techniques are being investigated in patients with penile cancer and might further decrease lymphadenectomy-related adverse effects. The management of patients with advanced disease has evolved to include multimodal treatment with systemic chemotherapy before surgical intervention and can include adjuvant chemotherapy after pelvic lymphadenectomy. The role of radiotherapy in the neoadjuvant or adjuvant setting remains largely unclear, owing to a lack of high-level evidence of possible benefits. New targeted therapies have shown efficacy in squamous cell carcinomas of other sites and might also prove effective in patients with penile cancer.

    The Authors try to show the possibility to combine radical excision with minimal invasiveness in the surgery of penile cancer. The focal point of every therapeutic decision is correct clinical staging. Unfortunately there's some confusion in the two international staging systems (TNM and Jackson's classification). In fact it's not clear the anatomical difference between epithelioma of the glans infiltrating corpus spongiosum and subcoronary epithelioma of the shaft infiltrating the corpora cavernosa. It's obvious that the infiltration of the corpora cavernosa is a far more aggressive oncological manifestation than that of tumour infiltrating the corpus spongiosum. So we consider Jackson's classification more congenial. In terms of surgery this anatomical independence makes it easy to consider the corpora cavernosa as a distinct entity, so they remain perfectly functional when separated from the glandulo-spongio-urethral unit with its vasculo-nervous bundle. This makes conservation of the erectile function, when clinical staging show us that the tumour is not infiltrating the corpora cavernosa. The Authors show their results, which seem to be rather good.

    The radical surgical option we propose for Peyronie's disease consists in removing the sclero-hyalinotic focus of disease and replacing it by an autologous dermal graft taken from the upper outer thigh area. Between 1981 and 1991, we operated 335 patients with IPP, 152 of whom underwent plaque excision and dermal graft. All could be assessed at two-year follow-up. Two main complications were observed: mild penile flexure due to scar retraction of the graft (35% of cases), and partial erectile deficit with decreased corporal rigidity (17% of cases). The degree of the graft retraction is linked to the individual's histologic response. A mild deviation of the penis can occur some months after surgery and is not a relapse flexure due to disease progression (as it should have evolutive characteristics) but is mere scar retraction and will spontaneously regress. As the patient will date the onset of a postoperative erectile deficit from the time of the operation, it is advisable to assess preoperatively the erectile ability of all patients. Furthermore, an impaired erectile response could result from hypoaesthesia of the glans, post-surgical stress, and fibrosis of the erectile tissue. A retrospective assessment of radical surgery cases involving plaque excision and dermal graft lead us to propose this option where precise indications apply, providing the presence of other alterations of the erectile function are pre-operatively assessed.

  17. Women's partnered orgasm consistency is associated with greater duration of penile-vaginal intercourse but not of foreplay.

    Weiss, Petr; Brody, Stuart

    2009-01-01

    It has been asserted that women's likelihood or consistency of partnered orgasm (her orgasm as a result of sexual activities with a partner) is determined by duration of foreplay, but not by duration of penile-vaginal intercourse. The objective was to examine the extent to which women's likelihood or consistency of partnered orgasm is associated with duration of foreplay, duration of penile-vaginal intercourse, and age. In a representative sample of the Czech population, 2,360 women reported their consistency of orgasm with a partner (from "never" to "almost every time"), and estimates of their typical durations of foreplay and of penile-vaginal intercourse. The association of consistency of partnered orgasm with typical durations of both foreplay and penile-vaginal intercourse. In univariate analyses, consistency of partnered orgasm was more associated with penile-vaginal intercourse duration than with foreplay duration (consistency also correlated negatively with age). In multivariate analysis, foreplay ceased to be a significant correlate of partnered orgasm consistency (the exclusion of respondents reporting a penile-vaginal intercourse duration of 1 minute or less did not alter the results). When both sexual activity categories are examined in tandem on a population level, women's likelihood or consistency of partnered orgasm is associated with penile-vaginal intercourse duration, but not with foreplay duration. In contrast to the assumptions of many sex therapists and educators, more attention should be given to improve the quality and duration of penile-vaginal intercourse rather than foreplay.

  18. Erect penile length and circumference dimensions of 1,661 sexually active men in the United States.

    2014-01-01

    Penile size continues to receive popular and empirical attention. Little is known about the process of self-measurement and whether the behaviors a man engages in to become erect for self-measurement are associated with his erect penile dimensions. The article aims to assess men's erect penile dimensions in a study in which the men would presumably be motivated to report accurate information about their penis size; and to explore associations between men's erect penile dimensions, their method of measurement, and their demographics. Data are from an Internet-based baseline phase of a large prospective daily diary study that compared men's use of a standard-sized condom to men's use of a condom sized to fit their erect penis. The main outcomes are participant characteristics, activities engaged in during self-measurement process, and self-reported erect penile length and circumference. For this sample of 1,661 men, the mean erect penile length was 14.15 cm (SD = 2.66; range = 4 to 26 cm), and the mean erect penile circumference was 12.23 cm (SD = 2.23; range = 3 to 19). Participant characteristics were not associated with measured length or circumference. Most men measured their penis while alone, using hand stimulation to become erect. In this sample of men who measured their erect penile length and circumference for the purposes of receiving a condom sized to fit their erect penis, we found a mean erect penile length of 14.15 cm and a mean erect penile circumference of 12.23 cm. The self-reported erect penile dimensions in this study are consistent with other penile dimension research. Also, findings suggest that mode of getting an erection may influence erect penile dimensions. Additionally, how a man becomes erect for self-measurement may be associated with his erect penile length and/or circumference. © 2013 International Society for Sexual Medicine.

  19. Targeting of regulated necrosis in kidney disease

    2018-03-01

    Full Text Available The term acute tubular necrosis was thought to represent a misnomer derived from morphological studies of human necropsies and necrosis was thought to represent an unregulated passive form of cell death which was not amenable to therapeutic manipulation. Recent advances have improved our understanding of cell death in acute kidney injury. First, apoptosis results in cell loss, but does not trigger an inflammatory response. However, clumsy attempts at interfering with apoptosis (e.g. certain caspase inhibitors may trigger necrosis and, thus, inflammation-mediated kidney injury. Second, and most revolutionary, the concept of regulated necrosis emerged. Several modalities of regulated necrosis were described, such as necroptosis, ferroptosis, pyroptosis and mitochondria permeability transition regulated necrosis. Similar to apoptosis, regulated necrosis is modulated by specific molecules that behave as therapeutic targets. Contrary to apoptosis, regulated necrosis may be extremely pro-inflammatory and, importantly for kidney transplantation, immunogenic. Furthermore, regulated necrosis may trigger synchronized necrosis, in which all cells within a given tubule die in a synchronized manner. We now review the different modalities of regulated necrosis, the evidence for a role in diverse forms of kidney injury and the new opportunities for therapeutic intervention. Resumen: La idea de que el término necrosis tubular aguda supone una denominación inapropiada se deriva de estudios morfológicos de necropsias humanas. La opinión generalizada ha sido que la necrosis representa una forma pasiva de muerte celular no regulada que no es susceptible de manipulación terapéutica. Los recientes avances han mejorado nuestra comprensión de la muerte celular en la lesión renal aguda. En primer lugar, la apoptosis origina una pérdida celular, pero no desencadena una respuesta inflamatoria. Sin embargo, los intentos rudimentarios de interferir en la apoptosis

  20. Conservative management of penile trauma may be complicated by abscess formation

    2014-11-01

    Full Text Available Blunt penile trauma during sexual activity, although highly underreported due to the associated patient embarrassment, constitutes a real urological emergency requiring immediate attention and possibly early surgical intervention. We report a case of a 58-year old man who presented with penile pain following excessive masturbation. Although there were no clinical signs of penile deformity or hematoma, magnetic resonance imaging revealed the presence of a rupture in the tunica albuginea. The patient opted for non-surgical management and his recovery period was complicated by the formation of an abscess at the site of the albugineal tear thus prolonging his hospital stay. The abscess was surgically drained and the patient reports to have normal erections at 3-month follow up.

    Full Text Available Amr A Faddan, Alexey V Aksenov, Carsten M Naumann, Klaus P Jünemann, Daniar K Osmonov Department of Urology and Pediatric Urology, University Hospital Schleswig-Holstein, Kiel, Germany Introduction: Priapism is the persistent erection resulting from dysfunction of the mechanisms that regulate penile swelling, stiffness, and sagging. It is a full or partial erection that persists for a period more than 4 hours beyond sexual stimulation and/or orgasm or is unrelated to sexual stimulation. Ischemic priapism should be managed in a step-by-step fashion. Objective: To demonstrate step-by-step management of stuttering refractory ischemic priapism. We report a case of stuttering refractory ischemic priapism. Moreover, we reviewed different approaches to priapism management in the literature. Case presentation: A 53-year-old male presented with a painful erection of 29 hours’ duration, probably caused by consumption of alcohol. The penile blood gas showed a pH of 7.08, PCO2 of 75 mmHg and PO2 of 39 mmHg. Aspiration was followed by irrigation of an α-adrenergic, Winter and T-shunt operations were preformed, and finally a semi-rigid penile prosthesis was implanted to overcome the refractory stuttering ischemic priapism. Conclusion: In case of stuttering refractory ischemic priapism, immediate implantation of a penile prosthesis is a simple and effective procedure that manages both the acute episode and the inevitable erectile dysfunction that would otherwise occur, while preserving penile length. Keywords: priapism, stuttering priapism, shunting operation, penile prosthesis

    Accurate data regarding the size of the erect penis are of great importance to several disciplines working with male patients, but little high-quality research exists on the subject, particularly in different ethnic groups and for erect penis size. The aim of this study was to create a nomogram of erect penile dimensions in a large sample of Middle Eastern men. A retrospective cohort study of 778 men (mean age 43.7; range 20-82) attending urological outpatient clinics in Saudi Arabia was conducted. Exclusion criteria were age under 18 years, a presenting complaint of small or short penis, Peyronie's disease or complaint of congenital curvature, clinical hypogonadism, and previous penile surgery or trauma. Three erect penile dimensions following induction of erection using intracavernosal injection of Quadrimix. Mean patient body mass index (BMI) was 29.09 (standard deviation [SD] 5.76). The mean suprapubic skin-to-penile tip erect length was 12.53 cm (SD 1.93); the mean erect length from the symphysis pubis to the penile tip was 14.34 cm (SD 1.86); and the mean erect shaft circumference was 11.50 cm (SD 1.74). A nomogram was constructed and statistical analysis performed, demonstrating a weak negative correlation between BMI and erect penile length measured from the suprapubic skin (r = -0.283, P Middle Eastern men can be used as a standard when advising men with small penis anxiety. The importance of measuring erect size and allowing for infra-pubic fat interference in measurement is emphasized. We envisage that this tool can be used to educate and reassure concerned men about the size of their penises. © 2015 International Society for Sexual Medicine.

  4. An innovative surgical technique for treating penile incarceration injury caused by heavy metallic ring

    S J Baruah

    2009-01-01

    Full Text Available Penile incarceration injury by heavy metallic ring is a rare genital injury. A man may place metal object for erotic or autoerotic purposes, for masturbation or increasing erection, and due to psychiatric disturbances are some of the reasons for a penile incarceration injury. The incarcerating injury results in reduced blood flow distal to the injury, leading to edema, ischemia, and sometimes gangrene. These injuries are divided into five grades and their treatment options are divided into four groups. Surgical techniques are reserved for the advanced grades (Grades IV and V. We describe an innovative surgical technique, which can be adopted in Grades II and III injuries.

    Penile agenesis is an extremely rare anomaly that results from absence of the genital tubercle or its failure to develop into a penis during embryonic life. Associated anomalies of the genitourinary and distal gastrointestinal tracts are frequently present. Imaging modalities, particularly MRI and cystography, play a crucial role in establishing the diagnosis and guiding further management. We report a child with penile agenesis with a urethroanal fistula and a blind-ending anterior urethra who had been reared as a male until presentation. (orig.)

    2007-01-01

    Full Text Available Penile gangrene associated with chronic renal failure is very uncommon. A 52-year-old man with diabetes mellitus, diffuse atherosclerosis, ischemic cardiomyopathy and end-stage renal disease presented with blackening of distal penis for 10 days. His general condition was poor and gangrene of prepuce and glans was noted. Doppler and magnetic-resonance angiography revealed bilateral internal iliac artery obstruction. He underwent trocar suprapubic cystostomy and was planned for partial penectomy. But he died of severe diabetic complications in the interim period. Penile gangrene is a manifestation of widespread vascular calcifications associated with end-stage renal disease and is a marker of poor prognosis.

    Jared Manwaring

    2015-01-01

    Full Text Available Two males presented to our urology department with complaints of bleeding and malodor from buried phallus within a suprapubic fat pad. Although both men had neonatal circumcisions, advanced penile carcinoma was found in both men. Formal penectomies showed high grade, poorly differentiated squamous cell carcinoma invading the corporal bodies and urethra. Buried penis represents a difficulty in early detection of suspicious lesions but may also provide an environment susceptible to poor hygiene and subsequent chronic inflammation. Patients with buried penis may be at a higher risk for development of invasive penile cancer and may benefit from regular and thorough genital exams.

  9. Penile metastases from primary bronchus carcinoma – A case report and literature review

    D.E. Du Plessis

    2015-03-01

    Conclusions: Cases of metastases to the penis are very rare and often carry a grave prognosis, as it is a late manifestation of malignant disease. The average survival from the diagnosis of penile metastases in our review was just under 4 months. It is however important to be aware and recognise this rare phenomenon, and differentiate it from primary penis cancer. Treatment of penile metastases is mostly palliative, but much can be done to improve the patient's quality of life. Early correct diagnosis may also alter the treatment of the primary tumour.

  10. Mastectomy skin necrosis after microsurgical breast reconstruction.

    2015-10-01

    Mastectomy skin necrosis represents a significant clinical morbidity after immediate breast reconstruction. In addition to aesthetic deformity, necrosis of the native mastectomy skin may require debridement, additional reconstruction, or prolonged wound care and potentially delay oncologic treatment. This study aims to evaluate patient and procedural characteristics to identify predictors of mastectomy skin necrosis after microsurgical breast reconstruction. A retrospective review was performed of all immediate microsurgical breast reconstructions performed at a single academic center. Patient records were queried for age, diabetes, active smoking, previous breast surgery, preoperative radiation, preoperative chemotherapy, body mass index, mastectomy type, mastectomy weight, flap type, autologous flap type, and postoperative mastectomy skin flap necrosis. There were 746 immediate autologous microsurgical flaps performed by three plastic surgeons at our institution during the study period. The incidence of mastectomy skin flap necrosis was 13.4%. Univariate analysis revealed a significantly higher incidence of mastectomy skin necrosis in patients with higher mastectomy weight (P mastectomy type. Multivariate analysis demonstrated statistically significant associations between mastectomy skin necrosis and both increasing mastectomy weight (odds ratio 1.348 per quartile increase, P = 0.009) and diabetes (odds ratio 2.356, P = 0.011). Increasing mastectomy weight and coexisting diabetes are significantly associated with postoperative mastectomy skin necrosis after microsurgical reconstruction. These characteristics should be considered during patient counseling, procedure selection, operative planning, and intraoperative tissue viability assessment. Copyright © 2015 Elsevier Inc.

  11. Penile Dysmorphic Disorder: Development of a Screening Scale.

    Veale, David; Miles, Sarah; Read, Julie; Troglia, Andrea; Carmona, Lina; Fiorito, Chiara; Wells, Hannah; Wylie, Kevan; Muir, Gordon

    2015-11-01

    Penile dysmorphic disorder (PDD) is shorthand for men diagnosed with body dysmorphic disorder, in whom the size or shape of the penis is their main, if not their exclusive, preoccupation causing significant shame or handicap. There are no specific measures for identifying men with PDD compared to men who are anxious about the size of their penis but do not have PDD. Such a measure might be helpful for treatment planning, reducing unrealistic expectations, and measuring outcome after any psychological or physical intervention. Our aim was, therefore, to validate a specific measure, termed the Cosmetic Procedure Screening Scale for PDD (COPS-P). Eighty-one male participants were divided into three groups: a PDD group (n = 21), a small penis anxiety group (n = 37), and a control group (n = 23). All participants completed the COPS-P as well as standardized measures of depression, anxiety, social phobia, body image, quality of life, and erectile function. Penis size was also measured. The final COPS-P was based on nine items. The scale had good internal reliability and significant convergent validity with measures of related constructs. It discriminated between the PDD group, the small penis anxiety group, and the control group. This is the first study to develop a scale able to discriminate between those with PDD and men anxious about their size who did not have PDD. Clinicians and researchers may use the scale as part of an assessment for men presenting with anxiety about penis size and as an audit or outcome measure after any intervention for this population.

  12. Patient perspectives on quality of life after penile cancer.

    Mortensen, Gitte Lee; Jakobsen, Jakob Kristian

    2013-07-01

    Penile cancer (PC) is a rare, but ominous disease. In 50-60% of squamous cell carcinomas of the penis, human papilloma virus infection, particularly with types 16 and 18, is part of the pathogenesis. Depending on cancer invasiveness, PC is treated with local resection of the glans and partial or total penectomy. This quality of life (QoL) study aimed at obtaining in-depth knowledge about patients' experiences with PC. A literature study was carried out to identify relevant topics for a semi-structured interview. Qualitative interviews with four former PC patients were transcribed verbatim and analysed using a medical anthropological approach. The analysis focused on the ways patients frame their disease experiences and relate the physical, sexual and emotional disease impact. Varying degrees of amputation affected the participants' sexual capabilities. Still, three participants (aged 66-72 years) said that their partner relationships were not negatively affected by the disease. In contrast, the impact on sexual function and self-esteem had been devastating to the fourth participant (aged 44 years) who was single and worried about the disease impeding his chance of finding love in life. For all participants, having had a potentially fatal disease put the physical disease impact into perspective. PC may greatly impact the psycho-sexual QoL of PC patients, particularly at a younger age and depending on their partnership status. Disease impact appears to be related to age, overall life situation and the cancer experience. The study was funded by an unrestricted research grant from Sanofi Pasteur MSD. not relevant.

    2015-05-01

    Most men seeking penile enhancement techniques have a normal penile size. They are either misinformed or suffer from penile dysmorphophobia and should be discouraged from undergoing invasive procedures. Less invasive techniques including penile extenders are not associated with major complications and may be beneficial from a psychological perspective. We conducted this study to assess the efficacy and safety of AndroPenis (Andromedical, Madrid, Spain) penile extender. Between December 2010 and December 2013, 163 men presented to our institution complaining of small penile length and/or girth. All patients received structured psychosexual counseling. Fifty-four patients were willing to use the AndroPenis penile extender after counseling. Patients with major psychiatric disorders were excluded from enrollment. The patients were instructed to wear the device between 4 and 6 hours per day for 6 months. Penile dimensions including flaccid stretched and erected lengths were measured at baseline and after 1, 3, 6, and 9 months. Erectile function was assessed at baseline and 9 months after treatment using the simplified International Index of Erectile Function (IIEF-5). An institutional nonstandardized questionnaire was used to evaluate patient satisfaction at the end of study. Penile length and girth enhancement as well as satisfaction rate and improvement in erectile function were assessed during follow-up. At 6-month follow-up, a mean gain of 1.7 ± 0.8, 1.3 ± 0.4, and 1.2 ± 0.4 cm was noted for the flaccid, stretched, and erected penile lengths, respectively (all P values < 0.001). During the off treatment period, there were no significant changes in penile lengths. No effect on penile girth was observed. Patient satisfaction survey revealed modest satisfaction. From 13 patients with mild baseline erectile dysfunction, nine patients reported normal erectile function after 9 months. Penile extender as a minimally invasive technique is safe and

  14. Programmed necrosis and necroptosis – molecular mechanisms

    Agata Giżycka

    2015-12-01

    Full Text Available Programmed necrosis has been proven vital for organism development and homeostasis maintenance. Its regulatory effects on functional activity of the immune system, as well as on pathways regulating the death mechanisms in cells with diminished apoptotic activity, including malignant cells, have been confirmed. There is also increasing evidence indicating necrosis involvement in many human pathologies. Contrary to previous beliefs, necrosis is not only a passive, pathological, gene-independent process. However, the current knowledge regarding molecular regulation of programmed necrosis is scarce. In part this is due to the multiplicity and complexity of signaling pathways involved in programmed necrosis, as well as the absence of specific cellular markers identifying this process, but also the ambiguous and imprecise international terminology. This review presents the current state of the art on molecular mechanisms of programmed necrosis. In particular, its specific and frequent form, necroptosis, is discussed. The role of RIP1 and RIP3 kinases in this process is presented, as well as the diverse pathways induced by ligation of tumor necrosis factor α, to its receptor, TNFR1, i.e. cell survival, apoptosis or necroptosis.

  15. Regulation of Tumor Progression by Programmed Necrosis

    2018-01-01

    Full Text Available Rapidly growing malignant tumors frequently encounter hypoxia and nutrient (e.g., glucose deprivation, which occurs because of insufficient blood supply. This results in necrotic cell death in the core region of solid tumors. Necrotic cells release their cellular cytoplasmic contents into the extracellular space, such as high mobility group box 1 (HMGB1, which is a nonhistone nuclear protein, but acts as a proinflammatory and tumor-promoting cytokine when released by necrotic cells. These released molecules recruit immune and inflammatory cells, which exert tumor-promoting activity by inducing angiogenesis, proliferation, and invasion. Development of a necrotic core in cancer patients is also associated with poor prognosis. Conventionally, necrosis has been thought of as an unregulated process, unlike programmed cell death processes like apoptosis and autophagy. Recently, necrosis has been recognized as a programmed cell death, encompassing processes such as oncosis, necroptosis, and others. Metabolic stress-induced necrosis and its regulatory mechanisms have been poorly investigated until recently. Snail and Dlx-2, EMT-inducing transcription factors, are responsible for metabolic stress-induced necrosis in tumors. Snail and Dlx-2 contribute to tumor progression by promoting necrosis and inducing EMT and oncogenic metabolism. Oncogenic metabolism has been shown to play a role(s in initiating necrosis. Here, we discuss the molecular mechanisms underlying metabolic stress-induced programmed necrosis that promote tumor progression and aggressiveness.

  18. Does penile rehabilitation have a role in the treatment of erectile dysfunction following radical prostatectomy?

    Blecher, Gideon; Almekaty, Khaled; Kalejaiye, Odunayo; Minhas, Suks

    2017-01-01

    In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post-radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

  4. Engaging men with penile cancer in qualitative research: reflections from an interview-based study.

    Witty, Karl; Branney, Peter; Bullen, Kate; White, Alan; Evans, Julie; Eardley, Ian

    2014-01-01

    To explore the challenges of engaging men with penile cancer in qualitative interview research. Qualitative interviewing offers an ideal tool for exploring men's experiences of illness, complementing and providing context to gendered health inequalities identified in epidemiological research on men. But conducting interviews with men can be challenging and embarking on a qualitative interview study with males can feel like a daunting task, given the limited amount of practical, gender-sensitive guidance for researchers. Reflecting on a researcher's experience of conducting qualitative research on men with penile cancer, this paper explores the potential challenges of interviewing this group, but also documents how engagement and data collection were achieved. This is a reflective paper, informed by the experiences of a male researcher (KW) with no nurse training, who conducted 28 interviews with men who had been treated for penile cancer. The researcher's experiences are reported in chronological order, from the methodological challenges of recruitment to those of conducting the interview. The paper offers a resource for the novice researcher, highlighting some advantages and disadvantages of conducting qualitative interview research as a nurse researcher, as well as recommendations on how to overcome challenges. Engaging men with penile cancer in qualitative interview raises practical, methodological, ethical and emotional challenges for the researcher. However, when these challenges are met, men will talk about their health. Methodological procedures must enable an open and ongoing dialogue with clinical gatekeepers and potential participants to promote engagement. Support from colleagues is essential for any interviewer, no matter how experienced the researcher is.

  7. One-sheet spiraling full thickness skin graft for penile resurfacing after paraffinoma excision

    Theddeus O.H. Prasetyono

    2011-08-01

    Full Text Available In the midst of on-going non-illicit practice of silicone or paraffin injection to enlarge penis, the author reported 3 cases of surgical treatment to resurface the body of the penis after excision of the destructed penile skin using full thickness skin graft. The skin excision was performed technically through penile body degloving procedure. Full thickness skin graft was then applied as a single sheet donor tissue to cover the denuded penile body spirally. The full thickness graft, which is relatively easy to be performed, is no doubt much thinner than a skin flap, while it also bears a smaller degree of secondary contraction than split skin graft. The color of the skin is considerably matched as it comes from the groin, which is a nearby area of penis. The size and skin sensitization of the penis looks to be natural. The only disadvantage is the common possibility of either spiral or circular junctional scar in between graft edges and between the graft and the penile mucosa and skin to develop hypertrophic scar. However, this possible scar problem applies also to any other surgical scar with any donor tissue. Fortunately, the 3 cases posed no scar problem and normal appearance. All the patients have also regained their normal sexual function. (Med J Indones 2011; 20:222-5Keywords: full thickness skin graft, paraffinoma, siliconoma, sexual function

  8. Sexual outcomes after partial penectomy for penile cancer: results from a multi-institutional study

    Salvatore Sansalone

    2017-01-01

    Full Text Available Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients′ sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25 represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25. Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15. Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15, orgasmic function (IIEF-9 and -10, sexual desire (IIEF-11 and -12, intercourse satisfaction (IIEF-6-8, and overall satisfaction (IIEF-13 and -14. Then, we also used Quality of Erection Questionnaire (QEQ, Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS and Self-Esteem and Relationship (SEAR to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

  9. Human Papilloma Virus: Prevalence, distribution and predictive value to lymphatic metastasis in penile carcinoma

    2013-07-01

    Full Text Available Objectives To evaluate the prevalence, distribution and association of HPV with histological pattern of worse prognosis of penile cancer, in order to evaluate its predictive value of inguinal metastasis, as well as evaluation of other previous reported prognostic factors. Material and Methods Tumor samples of 82 patients with penile carcinoma were tested in order to establish the prevalence and distribution of genotypic HPV using PCR. HPV status was correlated to histopathological factors and the presence of inguinal mestastasis. The influence of several histological characteristics was also correlated to inguinal disease-free survival. Results Follow-up varied from 1 to 71 months (median 22 months. HPV DNA was identified in 60.9% of sample, with higher prevalence of types 11 and 6 (64% and 32%, respectively. There was no significant correlation of the histological characteristics of worse prognosis of penile cancer with HPV status. Inguinal disease-free survival in 5 years did also not show HPV status influence (p = 0.45. The only independent pathologic factors of inguinal metastasis were: stage T ≥ T1b-T4 (p = 0.02, lymphovascular invasion (p = 0.04 and infiltrative invasion (p = 0.03. conclusions HPV status and distribution had shown no correlation with worse prognosis of histological aspects, or predictive value for lymphatic metastasis in penile carcinoma.

  10. Penile enhancement using a porcine small intestinal submucosa graft in a rat model.

    Leungwattanakij, S; Pummangura, N; Ratana-Olarn, K

    2006-01-01

    Several biodegradable materials have been experimented for penile enhancement, but none show the potential for clinical use. This study was designed to use porcine small intestinal submucosa (SIS) augmenting the normal tunica albuginea to increase the functional girth of the rat penis. In all, 20 adult male Sprague-Dawley rats constituted the study population. The animals were divided into two groups: group 1 consisted of the control (n=10) and group 2 (n=10) consisted of rats that underwent penile enhancement by a longitudinal I-shaped incision of the tunica albuginea on both sides, and the dissection of the plane between tunica albuginea and cavernosal tissue was carried out (n=10). The incision was then patched with a 3 x 10 mm2 piece of SIS, using a 6/0 nylon suture material. The penile length and mid-circumference were then measured using a Vernier Caliper before and 2 months after surgery. All rat penises underwent histological examination using Masson's trichome and Verhoff's van Giesen's stain for collagen and elastic fibers. The penile length, mid-circumference and degree of fibrosis score were expressed as mean+/-s.e. (standard error) and analyzed using a Wilcoxon rank-sum test. A statistical significance was accepted at P-value enhancement.

    Hsu, Geng-Long; Hill, James W; Hsieh, Cheng-Hsing; Liu, Shih-Ping; Hsu, Chih-Yuan

    2014-01-01

    Although penile implantation remains a final solution for patients with refractory impotence, undesirable postoperative effects, including penile size reduction and cold sensation of the glans penis, remain problematic. We report results of a surgical method designed to avoid these problems. From 2003 to 2013, 35 consecutive patients received a malleable penile implant. Of these, 15 men (the enhancing group) were also treated with venous ligation of the retrocoronal venous plexus, deep dorsal vein, and cavernosal veins. The remaining 20 men formed the control group, treated with only a penile implant. Follow-up ranged from 1.1 to 10.0 years, with an average of 6.7 ± 1.5 years. Although preoperative glanular dimension did not differ significantly between the two groups, significant respective difference at one day and one year postoperatively was found in the glanular circumference (128.8 ± 6.8 mm versus 115.3 ± 7.2 mm and 130.6 ± 7.2 mm versus 100.5 ± 7.3 mm; both Penhance the glans penis dimension in implant patients.

  12. Tourniquet application and epinephrine injection to penile skin: is it safe?

    2002-09-01

    Although a tourniquet is frequently used in penile surgery there is still no consensus on safe application time. The aim of the present study is to investigate the effect of malondialdehyde (MDA) levels and histological changes in skin flaps after penile tourniquet application and epinephrine injection. A total of 36 male white New Zealand rabbits were randomly divided into six groups each containing six animals. A Mathieu-like flap was raised in all of the groups and a tourniquet was applied and the penis was subjected to ischemia for 10, 20 and 40 min in groups 1, 2 and 3, respectively. The flaps were then allowed to reperfuse for 5 min. Biopsies for MDA measurement were harvested in these groups. Subcutaneous 1/200,000 epinephrine was injected into penile skin in group 4 and 5 rabbits and biopsies for MDA measurement were harvested 10 and 40 min after injection. The control group was anesthetized without tourniquet usage or epinephrine injection. Specimens taken from the harvested flaps of all groups were submitted for histological evaluation. The mean MDA levels in all experimental groups were higher than in the control group and the difference was statistically significant. Edema, congestion and extravasation were observed in groups 1, 2 and 3. Minimal congestion and edema were observed in group 4 and severe edema and extravasation in group 5. Tourniquet usage for a duration of less than 10 min is clearly safer than prolonged usage. Epinephrine injection to penile skin may show a deleterious effect on wound healing.

    Cis-diamminedichloride platinum II (DDP) was administered to eight patients with epidermoid carcinoma of the penis. Three of six adequately treated patients had an objective response: one patient achieved complete remission of 7 months duration and 2 patients had partial remissions of 8 and 2 months, respectively. DDP appears to be an active agent in the treatment of penile carcinoma.

  14. ROLE OF THE MITOCHONDRION IN PROGRAMMED NECROSIS

    Christopher eBaines

    2010-11-01

    Full Text Available In contrast to the programmed nature of apoptosis and autophagy, necrotic cell death has always been believed to be a random, uncontrolled process that leads to the accidental death of the cell. This dogma, however, is being challenged and the concept of necrosis also being programmed is gaining ground. In particular, mitochondria appear to play a pivotal role in the mediation of programmed necrosis. The purpose of this review, therefore, is to appraise the current concepts regarding the signaling mechanisms of programmed necrosis, with specific attention to the contribution of mitochondria to this process.

    2011-01-01

    Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

    Full Text Available Objectives: The Italian Society of Andrology, i.e. “Società Italiana di Andrologia” (S.I.A., launched on December 2014 a prospective, multicenter, monitored and internal review board approved Registry for penile implants, the “INSIST-ED” (Italian Nationwide Systematic Inventarisation of Surgical Treatment for ED Registry. Purpose of this first report is to present a baseline data analysis of the characteristics of penile implant surgery in Italy. Material and methods: The INSIST-ED Registry is open to all surgeons implanting penile prostheses (all brands, all models in Italy, providing anonymous patient, device, surgical procedure, outcome, follow-up data, for both first and revision surgeries. A Registry project Board overviews all the steps of the project, and a Registry Monitor interacts with the Registry implanting surgeons. Results: As by April 8, 2016, 31 implanting surgeons actively joined the Registry, entering 367 surgical procedures in its database, that comprise: 310 first implants, 43 prosthesis substitutions, 14 device explants without substitution. Implanted devices account for: 288 three-component devices (81,3%, 20 two-component devices (5,4%, 45 non-hydraulic devices (12,3%. Leading primary ED etiologies in first implant surgeries resulted: former radical pelvic surgery in 111 cases (35,8%, Peyronie’s disease in 66 cases (21,3%, diabetes in 39 cases (12,6%. Two intraoperative complications have been recorded. Main reasons for 57 revision surgeries were: device failure (52,6%, erosion (19,3%, infection (12,3%, patient dissatisfaction (10,5%. Surgical settings for patients undergoing a first penile implant were: public hospitals in 251 cases (81%, private environments in 59 cases (19%. Conclusions: The INSIST-ED Registry represents the first European experience of penile prosthesis Registry. This baseline data analysis shows that: three-pieces inflatable prosthesis is the most implanted device, leading etiology of

    2013-08-01

    Voluntary medical male circumcision decreases the risk in males of HIV infection through heterosexual intercourse by about 60% in clinical trials and 73% at post-trial followup. In 2007 WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended that countries with a low circumcision rate and high HIV prevalence expand voluntary medical male circumcision programs as part of a national HIV prevention strategy. Devices for adult/adolescent male circumcision could accelerate the pace of scaling up voluntary medical male circumcision. Detailed penile measurements of African males are required for device development and supply size forecasting. Consenting males undergoing voluntary medical male circumcision at 3 health facilities in the Iringa region, Tanzania, underwent measurement of the penile glans, shaft and foreskin. Age, Tanner stage, height and weight were recorded. Measurements were analyzed by age categories. Correlations of penile parameters with height, weight and body mass index were calculated. In 253 Tanzanian males 10 to 47 years old mean ± SD penile length in adults was 11.5 ± 1.6 cm, mean shaft circumference was 8.7 ± 0.9 cm and mean glans circumference was 8.8 ± 0.9 cm. As expected, given the variability of puberty, measurements in younger males varied significantly. Glans circumference highly correlated with height (r = 0.80) and weight (r = 0.81, each p <0.001). Stretched foreskin diameter moderately correlated with height (r = 0.68) and weight (r = 0.71, each p <0.001). Our descriptive study provides penile measurements of males who sought voluntary medical male circumcision services in Iringa, Tanzania. To our knowledge this is the first study in a sub-Saharan African population that provides sufficiently detailed glans and foreskin dimensions to inform voluntary medical male circumcision device development and size forecasting.

  19. Penile growth in response to hormone treatment in children with micropenis

    Rajendra B Nerli

    2013-01-01

    Full Text Available Introduction: Micropenis is defined as a stretched penile length 2.5 standard deviations less than the mean for age without the presence of any other penile anomalies, such as hypospadias. The term refers to a specific disorder that has a known set of causative factors and defined treatment modalities. The purpose of this study was to determine the effect of hormonal therapy on the gonadal response and penile growth in children who presented with micropenis. Materials and Methods: Children (<18 years who met the criteria for micropenis were included in this study. Children more than 11 years old were treated using a standard protocol of 1,500 to 2,000 IU human chorionic gonadotrophin administrated intramuscularly, once per week, for 6 weeks. Children less than 11 years old were treated with parenteral testosterone enanthate 25 mg once a month for 3 months. Response was evaluated in terms of change in testosterone levels and size of penis. Results: Serum testosterone levels at baseline and after 8 weeks of hormonal treatment were <20 and 449.4 ng/mL, respectively (P < 0.0001 in all children more than 11 years old. Stretched penile length after hormonal treatment increased from 15.54 to 37.18 mm in children less than 11 years old and from 26.42 to 64.28 mm in children more than 11 years old (P < 0.001. Conclusions: Management of isolated micropenis revolves around testosterone (direct administration or encouraging the patient′s body to make its own, and results with respect to increase in penile length are promising.

    To provide further quantitative and qualitative evidence about men who insert foreign liquids and objects into their penis and/or urethra. As part of a larger, cross-sectional study examining men (n = 445) with genital piercings (GP), 2 questions inquired whether the respondents had penile tattoos and/or inserted other materials, such as fluids and foreign objects, into their penis and urethra. Four different practices have been described in the literature: embedding (a) foreign objects and/or (b) liquids subcutaneously into penile tissue, as well as inserting (c) liquids and/or (d) foreign objects into the urethra. In our study, 354 (78%) men with GP responded to the 2 questions; 85 (24%) replied affirmatively and 68 (80%) provided comments. Respondents coined their practices penile and/or urethral "play." Two respondents embedded metal balls into their penis, 1 at age 13 injected water for penis enlargement; 11 inserted liquids into the urethra, and 63 reported insertion of 32 different objects, frequently urethral sounds or "sounding" (n = 33/52%) were mentioned. Major motivation themes focused on sexual stimulation and experimentation. Penile tattoos (n = 14) were also reported, mainly for esthetics. Few complications or STDs were reported. Basic demographic assumptions of those who participate in these actions were challenged, and this study provides evidence of a wider distribution of men using penile or urethral play, and "sounding." Clinician awareness of these practices are important to obtain accurate health histories, manage genitourinary tract complications, as well as provide applicable patient education.

  1. Intracellular serpins, firewalls and tissue necrosis.

    Marciniak, Stefan J; Lomas, David A

    2008-02-01

    Luke and colleagues have recently attributed a new role to a member of the serpin superfamily of serine proteinase inhibitors. They have used Caenorhabditis elegans to show that an intracellular serpin is crucial for maintaining lysosomal integrity. We examine the role of this firewall in preventing necrosis and attempt to integrate this with current theories of stress-induced protein degradation. We discuss how mutant serpins cause disease either through polymerization or now, perhaps, by unleashing necrosis.

  2. Penile vascular diagnostic categorization using penile duplex Doppler ultrasound: Differences in vascular hemodynamics parameters by differences in anatomic sampling location

    2016-10-01

    Full Text Available Objectives. In 2013 the International Society for Sexual Medicine(ISSM published the guidelines regarding the standard operating procedure (SOP for penile duplex Doppler ultrasound (PDDU. Although ISSM-SOP have given important strides in reducing interobserver variability in PDDU by procedural protocol and parameters these guidelines do not address the anatomic location along the penis at which hemodynamic measurements have to be done. In our opinion a “double sampling” may be interesting to detect the arteriogenic or venogenic nature of the erectile dysfunction (ED. In particular sampling measurements at the “crus” (at the level of the peno-scrotal junction may be significative for detection of veno-occlusive dysfunction (VOD,whereas an evaluation at “mid penis” (1/2 distance between peno-scrotal junction and coronal sulcus, may be useful to diagnose an arterial insufficiency (AI.

    Congenital penile torsion is a three-dimensional deformity with helical rotation of the distal corporal bodies with the penile crurae remaining fixed to the pubic rami. The first case of congenital penile torsion (hypospadias) was described in 1857. Isolated penile torsion is an under-reported anomaly. The reported incidence of isolated penile torsion is 1.7-27% and severe torsion is 0.7%. There are no studies available from Indian subcontinent on the incidence of isolated penile torque. The objective of this study was to determine the overall incidence of isolated penile torque in a north Indian population. A prospective study of deliveries of male children was conducted at our institute between April 2014 and June 2015. Penile torsion was measured using a small protractor either by the deviation of the median raphae or the direction of the meatus. Data were collected on the incidence of congenital isolated penile torsion, including the degree and direction (left or right) of torsion. Torsion was classified as mild (900). Statistical analysis was done using the chi-square test with variables of age and parity of the mother and weight of the child. There were 99 cases of isolated penile torque among 5018 male neonates assessed for penile torque. The incidence of isolated penile torque was 19.7 per 1000 births. The degree of torsion varied from 30 to 110° (average 51.46°). Seventy-nine percent (79%) of them had left side and 21% had right side torque (4:1). The degree of torsion was mild in 30%, with 20% having left side torque and 10% having right side torque (2:1). A moderate degree of torsion was seen in 69%: 84% of them had left torque and only 16% had right sided torque (5:1). Only one patient had severe left torque. The incidence of isolated congenital penile torsion was highest in the maternal age group of >30 years followed by the 26-30-year age group, and was lowest in 21-25 year age group. In multiparous women, the incidence of isolated congenital penile

    To explore the relationship of aging with the changes of endogenous carbon monoxide (CO), cGMP and cAMP contents in the penile tissues of rats. Twenty-four male rats were equally divided into an 8-month, a 16-month and a 24-month group, and their penile erection was detected by injecting apomorphine, their penile cavernous body harvested, and the contents of CO, cAPM and cGMP detected by improved dual wavelength spectrophotometry. The contents of CO, cAPM and cGMP were reduced with the increase of age, with statistically significant differences between the three age groups (P < 0.01). Aging significantly decreased the contents of CO, cAMP and cGMP in the penile tissues of the rats, which suggests that aging might play an important role in erectile dysfunction.

    2017-06-01

    Non-curvature penile deformities are prevalent and bothersome manifestations of Peyronie's disease (PD), but the quantitative metrics that are currently used to describe these deformities are inadequate and non-standardized, presenting a barrier to clinical research and patient care. To introduce erect penile volume (EPV) and percentage of erect penile volume loss (percent EPVL) as novel metrics that provide detailed quantitative information about non-curvature penile deformities and to study the feasibility and reliability of three-dimensional (3D) photography for measurement of quantitative penile parameters. We constructed seven penis models simulating deformities found in PD. The 3D photographs of each model were captured in triplicate by four observers using a 3D camera. Computer software was used to generate automated measurements of EPV, percent EPVL, penile length, minimum circumference, maximum circumference, and angle of curvature. The automated measurements were statistically compared with measurements obtained using water-displacement experiments, a tape measure, and a goniometer. Accuracy of 3D photography for average measurements of all parameters compared with manual measurements; inter-test, intra-observer, and inter-observer reliabilities of EPV and percent EPVL measurements as assessed by the intraclass correlation coefficient. The 3D images were captured in a median of 52 seconds (interquartile range = 45-61). On average, 3D photography was accurate to within 0.3% for measurement of penile length. It overestimated maximum and minimum circumferences by averages of 4.2% and 1.6%, respectively; overestimated EPV by an average of 7.1%; and underestimated percent EPVL by an average of 1.9%. All inter-test, inter-observer, and intra-observer intraclass correlation coefficients for EPV and percent EPVL measurements were greater than 0.75, reflective of excellent methodologic reliability. By providing highly descriptive and reliable measurements of

    To provide sexual function and quality of life outcomes in patients with severe penile deficiency who underwent radial forearm flap phalloplasty with and without penile prosthesis implantation. Patients with history of severe penile deficiency who underwent microsurgical radial forearm flap phalloplasty with and without penile prosthesis implantation between 2007 and 2014 were identified. They completed a set of web-based validated questionnaires including the International Index of Erectile Function, the Pediatric Penile Perception Score, the Sexual Quality of Life for Men, and several items addressing general quality of life. Outcomes were compared between groups. Nine of the 12 identified patients who had prosthesis after phalloplasty and 4 out of the 7 phalloplasty-only patients completed the survey, resulting in an overall response rate of 68%. Among the phalloplasty-prosthesis patients, 66% reported current sexual activity and 78% reported regular masturbation, whereas 1 of the 4 phalloplasty-only patients reported both. Prosthesis patients scored notably higher in all domains of the International Index of Erectile Function except for sexual desire. In contrast, they demonstrated similar scores of penile perception, as well as general and sexual quality of life. Among patients who have undergone flap phalloplasty, the subsequent placement of penile prosthesis appears to effectively allow for both intercourse and masturbation, resulting in measurable improvements in orgasmic function, intercourse satisfaction, and overall sexual satisfaction. Despite these important benefits, prosthesis placement does not appear to result in improvements in penile perception scores, or general or sexual quality of life. Copyright © 2017 Elsevier Inc.

  12. MicroRNA Expression Profile in Penile Cancer Revealed by Next-Generation Small RNA Sequencing.

    Li Zhang

    Full Text Available Penile cancer (PeCa is a relatively rare tumor entity but possesses higher morbidity and mortality rates especially in developing countries. To date, the concrete pathogenic signaling pathways and core machineries involved in tumorigenesis and progression of PeCa remain to be elucidated. Several studies suggested miRNAs, which modulate gene expression at posttranscriptional level, were frequently mis-regulated and aberrantly expressed in human cancers. However, the miRNA profile in human PeCa has not been reported before. In this present study, the miRNA profile was obtained from 10 fresh penile cancerous tissues and matched adjacent non-cancerous tissues via next-generation sequencing. As a result, a total of 751 and 806 annotated miRNAs were identified in normal and cancerous penile tissues, respectively. Among which, 56 miRNAs with significantly different expression levels between paired tissues were identified. Subsequently, several annotated miRNAs were selected randomly and validated using quantitative real-time PCR. Compared with the previous publications regarding to the altered miRNAs expression in various cancers and especially genitourinary (prostate, bladder, kidney, testis cancers, the most majority of deregulated miRNAs showed the similar expression pattern in penile cancer. Moreover, the bioinformatics analyses suggested that the putative target genes of differentially expressed miRNAs between cancerous and matched normal penile tissues were tightly associated with cell junction, proliferation, growth as well as genomic instability and so on, by modulating Wnt, MAPK, p53, PI3K-Akt, Notch and TGF-β signaling pathways, which were all well-established to participate in cancer initiation and progression. Our work presents a global view of the differentially expressed miRNAs and potentially regulatory networks of their target genes for clarifying the pathogenic transformation of normal penis to PeCa, which research resource also

    2013-05-01

    WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The sensitivity of the foreskin and its importance in erogenous sensitivity is widely debated and controversial. This is part of the actual public debate on circumcision for non-medical reason. Today some studies on the effect of circumcision on sexual function are available. However they vary widely in outcome. The present study shows in a large cohort of men, based on self-assessment, that the foreskin has erogenous sensitivity. It is shown that the foreskin is more sensitive than the uncircumcised glans mucosa, which means that after circumcision genital sensitivity is lost. In the debate on clitoral surgery the proven loss of sensitivity has been the strongest argument to change medical practice. In the present study there is strong evidence on the erogenous sensitivity of the foreskin. This knowledge hopefully can help doctors and patients in their decision on circumcision for non-medical reason. To test the hypothesis that sensitivity of the foreskin is a substantial part of male penile sensitivity. To determine the effects of male circumcision on penile sensitivity in a large sample. The study aimed at a sample size of ≈1000 men. Given the intimate nature of the questions and the intended large sample size, the authors decided to create an online survey. Respondents were recruited by means of leaflets and advertising. The analysis sample consisted of 1059 uncircumcised and 310 circumcised men. For the glans penis, circumcised men reported decreased sexual pleasure and lower orgasm intensity. They also stated more effort was required to achieve orgasm, and a higher percentage of them experienced unusual sensations (burning, prickling, itching, or tingling and numbness of the glans penis). For the penile shaft a higher percentage of circumcised men described discomfort and pain, numbness and unusual sensations. In comparison to men circumcised before puberty, men circumcised during adolescence or

    2017-10-01

    We examined the effects of treatment on the psychological well-being of patients with localized or advanced penile cancer using screening questionnaires to determine the consecutive need for psychosocial care. Penile cancer is a rare, but highly aggressive, malignancy. The psychological stress of patients with penile cancer arises from the cancer diagnosis per se and the corresponding consequences of treatment. In addition, cancer-specific distress results (eg, fear of metastasis, progression, relapse, death). Studies of the psychosocial stress of penile cancer patients are rare. We undertook a prospective analysis of the data from patients with penile cancer who had undergone surgery or chemotherapy from August 2014 to October 2016 at our department. Patients were evaluated using standardized questionnaires for stress screening and the identification for the need for psychosocial care (National Comprehensive Cancer Network Distress Thermometer and Hornheider screening instrument) and by assessing the actual use of psychosocial support. The average stress level was 4.5. Of all the patients, 42.5% showed increased care needs at the time of the survey. Younger patients, patients undergoing chemotherapy, and patients with recurrence were significantly more integrated with the psychosocial care systems. Finally, 67% of all patients received inpatient psychosocial care. Owing to the potentially mutilating surgery, patients with penile cancer experience increased psychological stress and, consequently, have an increased need for psychosocial care. Therefore, the emotional stress of these patients should be recognized and support based on interdisciplinary collaboration offered. Copyright © 2017 Elsevier Inc. All rights reserved.

    Penile prostheses (PPs) are a discrete, well-tolerated treatment option for men with medical refractory erectile dysfunction. Despite the increasing prevalence of erectile dysfunction, multiple series evaluating inpatient data have found a decrease in the frequency of PP surgery during the past decade. To investigate trends in PP surgery and factors affecting the choice of different PPs in New York State. This study used the New York State Department of Health Statewide Planning and Research Cooperative (SPARCS) data cohort that includes longitudinal information on hospital discharges, ambulatory surgery, emergency department visits, and outpatient services. Patients older than 18 years who underwent inflatable or non-inflatable PP insertion from 2000 to 2014 were included in the study. Influence of patient demographics, surgeon volume, and hospital volume on type of PP inserted. Since 2000, 14,114 patients received PP surgery in New York State; 12,352 PPs (88%) were inflatable and 1,762 (12%) were non-inflatable, with facility-level variation from 0% to 100%. There was an increasing trend in the number of annual procedures performed, with rates of non-inflatable PP insertion decreasing annually (P New York State and the results might not be generalizable to men in other states. Also, patient preference was not accounted for in these analyses, which can play a role in PP selection. During the past 14 years, there has been an increasing trend in inflatable PP surgery for the management of erectile dysfunction. Most procedures are performed in the ambulatory setting and not previously captured by prior studies using inpatient data. Kashanian JA, Golan R, Sun T, et al.

    Full Text Available Keisho Hirota1,2, Masayuki Akimoto1,3, Toshiaki Katsura21Department of Ophthalmology, Kyoto Medical Center, National Hospital Organization, 2Internal Medicine, Kyoto Medical Center, 3Clinical Research Center, Kyoto Medical Center, Kyoto, JapanPurpose: The report of a case of bilateral acute retinal necrosis after herpetic meningitis.Case report: A 47-year-old man was admitted with the chief complaint of persistent high fever and transient loss of consciousness. Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

  17. Penile fracture with disruption of both cavernosal bodies and complete urethral rupture in a 15-years-old male: Delayed surgical approach

    2016-09-01

    Full Text Available Penile fracture is defined as the traumatic rupture of the tunica albuginea of the corpus cavernosa usually associated to trauma during sexual intercourse or masturbation. Historically penile fracture has been managed conservatively, but contemporary management includes early surgical exploration. The case presents a 15-year-old male who suffered a blunt penile trauma and was first managed with cystostomy and no penile exploration. Five months after trauma was submitted to definitive surgical correction of both, urethral rupture and bilateral corporal fracture. The proposed surgical techinique was a diamond-shape corpora anastomosis. Surgery did well and after 3 years he presented no late complications.

  18. Penile prosthesis implant with bi-triangular excision and graft for surgical therapy of Peyronie’s disease: A case report

    Alexandre de Freitas Miranda

    2016-01-01

    Full Text Available We present a case of a 65-year-old man, who presented with moderate erectile dysfunction and a dorsal penile deviation of 60° caused by Peyronie’s disease. The patient underwent bi-triangularshaped plaque excision, followed by grafting and implantation of inflatable penile prosthesis. Complete penile straightening, without mechanical or geometric abnormalities, was achieved using bi-triangular excision and grafting. Postoperatively, the patient reported high satisfaction with the results and could perform sexual intercourse naturally. This novel technique corrects any degree of penile curvature, permits malleable and semi-rigid penile prosthesis implantation, avoids penile length loss, and eliminates additional incisions. To our knowledge, this case is the first in the literature in which the bi-triangular technique was successfully used for penile prosthesis implantation secondary to Peyronie’s disease. This new technique appears to be a good solution to correct penile curvature during penile prosthesis implantation for the treatment of Peyronie’s disease associated with erectile dysfunction.

    Sclerosing lymphangitis of the penis is a benign, under-reported condition consisting of a asymptomatic firm cord-like swelling around the coronal sulcus of the penis usually affecting men in the second or third decade of life. Penile oedema and erosions are rarely reported. Clinical signs may be remarkable contrasting with the self-limited character of the disease. We report a new case of sclerosing lymphangitis of the penis occurring in a 59-year-old patient marked by penile swelling and several overlying skin erosions, and discuss the clinical features and the pathogenesis aspects of the disease. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

  2. Malignant priapism due to penile metastases: Case series and literature review

    Francesco De Luca

    2016-07-01

    Full Text Available Malignant priapism secondary to penile metastases is a rare condition. This term was originally used by Peacock in 1938 to describe a condition of painful induration and erection of the penis due to metastatic infiltration by a neoplasm. In the current literature there are 512 case reports. The primary tumor sites are bladder, prostate and rectum. The treatment has only palliative intent and consists of local tumor excision, penectomy, radiotherapy and chemotherapy. We present one case of malignant priapism originated from prostate cancer, and two from urothelial carcinoma of the bladder. Different approaches in diagnosis and therapy were performed. The entire three patient reported a relief of the pain following the treatment, with an improvement of their quality of life, even though it was only temporary as a palliative. Malignant priapism is a rare medical emergency. Penile/pelvis magnetic resonance imaging (MRI scan and corporal biopsies are considered an effective method of diagnosis of the primary organ site.

    2017-04-01

    Candida albicans is the most common pathogen that causes balanoposthitis. It often causes recurrence of symptoms probably due to its antifungal resistance. A significant number of balanitis Candida albicans isolates are resistant to azole and terbinafine antifungal agents in vitro. However, balanoposthitis caused by fluconazole- and terbinafine-resistant Candida albicans has rarely been reported. Here, we describe a case of a recurrent penile infection caused by fluconazole- and terbinafine-resistant Candida albicans, as well as the treatments administered to this patient. The isolate from the patient was tested for drug susceptibility in vitro. It was sensitive to itraconazole, voriconazole, clotrimazole and amphotericin B, but not to terbinafine and fluconazole. Thus, oral itraconazole was administrated to this patient with resistant Candida albicans penile infection. The symptoms were improved, and mycological examination result was negative. Follow-up treatment of this patient for 3 months showed no recurrence.

    2017-04-01

    Full Text Available Acute tracheal dilatation, due to an overinflated cuff, has been reported early in the course of mechanical ventilation through an endotracheal tube. Tracheal stoma necrosis is a rare complication, but such can accompany acute tracheal dilation. Herein, we report a case of tracheal necrosis 9 days following tracheostomy placement in a 71-year old woman associated with overinflation of the tracheal tube cuff. This case report aims to 1 add to the scant body of knowledge about the diagnosis and management for the patients with tracheal stoma necrosis and 2 raise awareness for error-traps in interpreting diagnostic images, specifically satisfaction of search error, inattentional blindness error, and alliterative error.

  6. Venous Ligation: A Novel Strategy for Glans Enhancement in Penile Prosthesis Implantation

    Geng-Long Hsu

    2014-01-01

    Full Text Available Although penile implantation remains a final solution for patients with refractory impotence, undesirable postoperative effects, including penile size reduction and cold sensation of the glans penis, remain problematic. We report results of a surgical method designed to avoid these problems. From 2003 to 2013, 35 consecutive patients received a malleable penile implant. Of these, 15 men (the enhancing group were also treated with venous ligation of the retrocoronal venous plexus, deep dorsal vein, and cavernosal veins. The remaining 20 men formed the control group, treated with only a penile implant. Follow-up ranged from 1.1 to 10.0 years, with an average of 6.7 ± 1.5 years. Although preoperative glanular dimension did not differ significantly between the two groups, significant respective difference at one day and one year postoperatively was found in the glanular circumference (128.8 ± 6.8 mm versus 115.3 ± 7.2 mm and 130.6 ± 7.2 mm versus 100.5 ± 7.3 mm; both P<0.05, radius (38.8 ± 2.7 mm versus 37.1 ± 2.8 mm and 41.5 ± 2.6 mm versus 33.8 ± 2.9 mm; latter P<0.01, and satisfaction rate (91.7% versus 53.3%, P<0.01 as well. Based on our results, selective venous ligation appears to enhance the glans penis dimension in implant patients.

  7. Myiasis associated with penile carcinoma: a new trend in developing countries?

    Leandro Koifman

    Full Text Available ABSTRACT Objectives The aim of this study is to report an unusual form of penile cancer presentation associated with myiasis infestation, treatment options and outcomes. Materials and Methods We studied 10 patients with suspected malignant neoplasm of the penis associated with genital myiasis infestation.

  9. Dipyridamole reduces penile apoptosis in a rat model of post-prostatectomy erectile dysfunction

    Omer Kutlu

    Full Text Available ABSTRACT Purpose: Despite the nerve-sparing technique, many patients suffer from erectile dysfunction after radical prostatectomy (RP due to cavernous nerve injury. The aim of this study was to evaluate dipyridamole as a potential treatment agent of post-radical prostatectomy erectile dysfunction. Material and methods: A total of 18 male Sprague-Dawley rats were randomized into three experimental Groups (SHAM+DMSO, BCNI+DMSO and BCNI+DIP. An animal model of bilateral cavernous nerve crush injury (BCNI was established to mimic the partial nerve damage during nerve-sparing RP. After creating of BCNI, dimethyl sulphoxide (DMSO was administered transperitoneally as a vehicle to SHAM+DMSO and BCNI+DMSO Groups. BCNI+DIP Group received dipyiridamole (10mg/kg/day as a solution in DMSO for 15 days. Afterwards, rats were evaluated for in vivo erectile response to cavernous nerve stimulation. Penile tissues were also analyzed biochemically for transforming growth factor-β1 (TGF-β1 level. Penile corporal apoptosis was determined by TUNEL method. Results: Erectile response was decreased in rats with BCNI and there was no significant improvement with dipyridamole treatment. TGF-β1 levels were increased in rats with BCNI and decreased with dipyridamole treatment. Dipyridamole led to reduced penile apoptosis in rats with BCNI and there was no significant difference when compared to sham operated rats. Conclusions: Although fifteen-day dipyridamole treatment has failed to improve erectile function in rats with BCNI, the decline in both TGF-β1 levels and apoptotic indices with treatment may be helpful in protecting penile morphology after cavernous nerve injury.

    High levels of circulating C-reactive protein (CRP) have recently been linked to poor clinical outcome in various malignancies. The aim of this study was to evaluate the prognostic significance of the preoperative serum CRP level in patients with squamous cell carcinoma (SCC) of the penis. This retrospective analysis included 79 penile cancer patients with information about their serum CRP value prior to surgery who underwent either radical or partial penectomy at two German high-volume centers (Ulm University Medical Center and Hannover Medical School) between 1990 and 2010. They had a median (mean) follow-up of 23 (32) months. A significantly elevated CRP level (>15 vs. ≤ 15 mg/l) was found more often in patients with an advanced tumor stage (≥pT2) (38.9 vs. 11.6%, p=0.007) and in those with nodal disease at diagnosis (50.0 vs. 14.6%, p=0.007). However, high CRP levels were not associated with tumor differentiation (p=0.53). The Kaplan-Meier 5-year cancer-specific survival (CSS) rate was 38.9% for patients with preoperative CRP levels above 15 mg/l and 84.3% for those with lower levels (p=0.001). Applying multivariate analysis and focusing on the subgroup of patients without metastasis at the time of penile surgery, both advanced local tumor stage (≥pT2; HR 8.8, p=0.041) and an elevated CRP value (>15 mg/l; HR 3.3, p=0.043) were identified as independent predictors of poor clinical outcome in patients with penile cancer. A high preoperative serum CRP level was associated with poor survival in patients with penile cancer. If larger patient populations confirm its prognostic value, its routine use could enable better risk stratification and risk-adjusted follow-up of patients with SCC of the penis

    Full Text Available Objective: To evaluate and present satisfaction rates of our patients and their partners after 3 part inflatable penile prosthesis implantation. Materials and methods: We searched our hospital electronic data for patients who underwent inflatable penile prosthesis implantation between January 2008 and July 2013. Computer and archived file data were used to get information and reach the patients. We made telephone calls to patients and asked questionnaires about self and partner satisfaction rates. Results: 36 patients underwent prosthesis implantation during the 5 year period. We were able to reach by telephone call 18 of them. The mean age of 18 patients was 55.7 ± 9.4 years and mean body mass index was 24.6 ± 2.1 kg/m2. The etiology was diabetes mellitus on 14 (77.8% and radical pelvic surgery on 4 (22.2% patients. 14 of 18 patients had penile Doppler ultrasound test. Doppler ultrasound demonstrated venous insufficiency in 8 and arterial insufficiency in 6 patients. Mean time from implantation to study was 20.8 ± 13.9 months. Out of 18 patients 2 had prosthesis removal operation because of infection in one patient and perforation in the other. Satisfaction rate was 88.9%, and recommendation rate was 94.4%. Causes of dissatisfaction were pain in one patient and insufficient rigidity plus shortening of the penis in the other one. Partner satisfaction rate was 94.4%. Conclusion: Penile Prosthesis Implantation (PPI is the gold standard treatment of erectile dysfunction (ED irresponsive to medical treatment. Infection and mechanical failure rates are going to be less according to the improvements in synthetic materials and coverings of the prosthesis, so patient and partner satisfaction rates will be higher.

    Full Text Available Aim: We examine the efficacy of the low dose, high dose and on demand use of sertraline on patients with primary premature ejaculation.The value of penile biothesiometry on interpretation of responses from these treatments is also evaluated. Material and Method: A total of 70 men, 23 to 55 years old(mean age 36.4,with premature ejaculation were randomized into two treatment groups,each consisting of 35 patients,receiving placebo,sertraline, in a fashion.Because 10 patients dropped out for some reason,the study was completed with 32 patients in placebo,28 patients in sertraline groups. The study was divided into five periods in order, i.e. before treatment(BT, low dose(LD, high dose(HD, on demand(OD and after treatment(AT.Patients did not use any of these drugs during BT and AT periods. Drug visits, intravaginal ejaculation latencies and sexual satisfaction score of the previous period were recorded,penile biothesiometric analysis was performed as well. Results: The percentage of patients with a SES score ‘moderate’ or ‘good’ for placebo group on LD period, was 25%;for sertraline group was 46.4%, but on HD and OD periods it was about %40 for placebo group and 71.4% for sertraline group.According to latancies and penile biothesiometric data,both sertraline group was superior to placebo in all LD, HD and OD periods(pOD>LD.Drug caused non-serious side effects in 10 of 60 patients(16.6%. Discussion: Sertraline is effective in primary premature ejaculation.On demand use of both drugs following a two week high dose use,is an effective treatment for primary premature ejaculation with less side effects. Penile biothesiometry can be used to evaluate the efficacy of pharmacotherapy in primary premature ejaculation in place of intravaginal latency measurements and satisfaction scores.

  14. Intralesional Injection of Collagenase Clostridium histolyticum May Increase the Risk of Late-Onset Penile Fracture.

    2018-04-01

    The use of intralesional injection of collagenase Clostridium histolyticum (CCH) has become a valid treatment option in the management of Peyronie's disease (PD). Multiple studies have shown the drug's safety and efficacy. However, sparse literature exists on the utility of the injection protocol's 14-day "observation period," in which patients are instructed to abstain from all sexual activity. To summarize the contemporary literature and report on our series of patients treated with CCH in an effort to explore the effectiveness of the postinjection observation period. We retrospectively reviewed the clinical course of men treated with at least one CCH injection at our institution from April 2014 through February 2017. The main outcome measure for our cohort was complication rate (hematoma, fracture). Secondary outcomes included progression to corrective surgery. Of the 102 patients treated, 5 (4.9%) developed a corporal fracture. Four of these occurred outside the 14-day observation period. One fracture was managed conservatively and the rest underwent surgical exploration and repair. Twelve penile hematomas were reported; one of these patients was surgically explored because of suspicious magnetic resonance imaging findings. Seven patients (6.9%) progressed to corrective surgery. Penile hematoma and corporal fracture are serious complications that must be discussed with patients before initiation of intralesional CCH treatment. Little evidence exists to direct physicians on the proper management of post-CCH penile fractures; many caregivers and patients elect to treat these injuries conservatively and avoid surgical exploration. Further studies are warranted to generate discussion and reassessment regarding the safety and effectiveness of this 14-day observation period.

    2011-12-01

    Despites the debates on penile girth enhancement (PGE), demands for enhancement are increasing. Recently, various fillers have been widely used for soft tissue augmentation with proven efficacy and safety. To identify the feasibility and efficacy of PGE by injection of filler. Fifty patients with subjective small penis who visited Korea University Guro outpatient clinic were enrolled and prospectively followed. Restylane Sub-Q (Q-med, Upssala, Sweden) was injected into the fascial layer of penile body via 21G cannula with "Back & Forth Technique" and homogenized with a roller. From April 2006 to February 2008, 50 patients were enrolled and 41 patients were followed until 18 months after PGE. Changes in penile girth at midshaft were measured by tapeline at 1 and 18 months. Patient's visual estimation of residual volume (Gr 0-4), patient's satisfaction (Gr 0-4), and any adverse reactions were also evaluated. Mean injected volume was 20.56 cc (18-22). Compared with basal girth of 7.48 ± 0.35 cm, maximal circumference was significantly increased to 11.41 ± 0.34 cm at 1 month (P < 0.0001) and maintained as 11.26 ± 0.33 cm until 18 months. In patient's visual estimation, two patients complained the decrease as Gr 3 with focal depression at 1 month. At 18 months, all patients answered as Gr 4 without asymmetry. Patient's and partner's satisfaction score was 3.71 ± 0.46 and 3.65 ± 0.48 at 1 month and 3.34 ± 0.53 and 3.38 ± 0.49 at 18 months. There were no inflammatory signs or serious adverse reactions in all cases. Considering the property of material, methods, and follow-up results of 18 months, PGE using filler is a very effective and safe technique for penile augmentation. © 2010 International Society for Sexual Medicine.

    1978-08-01

    Subcutaneous fat necrosis of the newborn (SFNN) developed in a 1-week-old black boy. His mother had received numerous medications for eclampsia. Birth was by Caesarean section and complicated by meconium aspiration. There were numerous nodules over the back, buttocks and extremities that yielded a caseous-like material. Microscopically, these nodules showed crystallization and necrosis of the fat. Hypoglycemia, pneumonia, oliguria, thrombocytopenia, seizures and urinary infection were associated with the cutaneous problem and led to a fatal outcome 2 weeks after birth.

    1987-01-01

    Two obese women with thrombotic disease complicated by necrosis of the breast are described. In one patient the reaction started after a few days of coumarin treatment and progressed to severe necrosis requiring mastectomy. The other patient was not on anticoagulant therapy when the breast reaction started and the clinical course was less severe. The radiographic appearance was characterized by thickening of the breast trabeculae, increased density of the breast and skin thickening. Although the radiographic findings are non-specific, the correct diagnosis can be suggested if combined with appropriate clinical information. The disease process may mimic breast cancer of the inflammatory type, clinically as well as radiographically. (orig.)

  20. Vacuum therapy in penile rehabilitation after radical prostatectomy: review of hemodynamic and antihypoxic evidence.

    Qian, Sheng-Qiang; Gao, Liang; Wei, Qiang; Yuan, Jiuhong

    2016-01-01

    Generally, hypoxia is a normal physiological condition in the flaccid penis, which is interrupted by regular nocturnal erections in men with normal erectile function. [1] Lack of spontaneous and nocturnal erections after radical prostatectomy due to neuropraxia results in persistent hypoxia of cavernosal tissue, which leads to apoptosis and degeneration of cavernosal smooth muscle fibers. Therefore, overcoming hypoxia is believed to play a crucial role during neuropraxia. The use of a vacuum erectile device (VED) in penile rehabilitation is reportedly effective and may prevent loss of penile length. The corporal blood after VED use is increased and consists of both arterial and venous blood, as revealed by color Doppler sonography and blood gas analysis. A similar phenomenon was observed in negative pressure wound therapy (NPWT). However, NPWT employs a lower negative pressure than VED, and a hypoperfused zone, which increases in response to negative pressure adjacent to the wound edge, was observed. Nonetheless, questions regarding ideal subatmospheric pressure levels, modes of action, and therapeutic duration of VED remain unanswered. Moreover, it remains unclear whether a hypoperfused zone or PO 2 gradient appears in the penis during VED therapy. To optimize a clinical VED protocol in penile rehabilitation, further research on the mechanism of VED, especially real-time PO 2 measurements in different parts of the penis, should be performed.

  1. Role of Schwann cells in the regeneration of penile and peripheral nerves

    Lin Wang

    2015-01-01

    Full Text Available Schwann cells (SCs are the principal glia of the peripheral nervous system. The end point of SC development is the formation of myelinating and nonmyelinating cells which ensheath large and small diameter axons, respectively. They play an important role in axon regeneration after injury, including cavernous nerve injury that leads to erectile dysfunction (ED. Despite improvement in radical prostatectomy surgical techniques, many patients still suffer from ED postoperatively as surgical trauma causes traction injuries and local inflammatory changes in the neuronal microenvironment of the autonomic fibers innervating the penis resulting in pathophysiological alterations in the end organ. The aim of this review is to summarize contemporary evidence regarding: (1 the origin and development of SCs in the peripheral and penile nerve system; (2 Wallerian degeneration and SC plastic change following peripheral and penile nerve injury; (3 how SCs promote peripheral and penile nerve regeneration by secreting neurotrophic factors; (4 and strategies targeting SCs to accelerate peripheral nerve regeneration. We searched PubMed for articles related to these topics in both animal models and human research and found numerous studies suggesting that SCs could be a novel target for treatment of nerve injury-induced ED.

    2017-01-01

    Objective: To present our experience of treatment of complex anterior urethral strictures using penile skin flap. Study Design: Descriptive, case series. Place and Duration of Study: Department of urology Combined Military Hospital Malir Cantonment, Karachi and Armed Forces Institute of Urology, Rawalpindi from Jan 2012 to Feb 2014. Material and Methods: Total 18 patients with complex anterior urethral strictures and combined anterior and bulborurethral strictures were included. Patients underwent repair using Orandi or circularfacio-cutaneous penile skin flap depending upon the size and site of stricture. First dressing was changed after two days and an in dwelling silicone two way foleycatheter was kept in place for three weeks. Graft was assessed with regards to local infection, fistula formation and restricturing. Re-stricture was assessed by performing uroflowmetery at 6 months and 1 year. Ascending urethrogram was reserved for cases with less than 10 ml/sec Q max on uroflowmetery. Repair failure was considered when there was a need for any subsequent urethral procedure asurethral dilatation, dorsal visual internal urethrotomy, or urethroplasty. Results: Overall success rate was 83.3 percent. Of all the patients operated 1(5.6 percent) had infection with loss of flap, 3(16.7 percent) had urethral fistula and none had re stricture confirmed by uroflowmetery. Conclusion: In our study the excellent results of the penile skin flap both in anterior urethral strictures and combined anterior and bulbar urethral strictures are quite encouraging. It is easy to harvest and seems anatomically more logical. (author)

  3. [Penis-preserving surgery in patients with primary penile urethral cancer].

    Maek, M; Musch, M; Arnold, G; Kröpfl, D

    2014-12-01

    Primary urethral cancer in males is a rare entity with only approximately 800 cases described, which is why it is difficult to formulate evidence-based guidelines for treatment. For tumors in the pT2 stage with a localization distal to the membranous urethra, a penis-preserving operation can be carried out. In the period from November 2006 to February 2014 a total of 4 patients with primary urethral cancer underwent a penis-preserving urethral resection. The tumor characteristics and treatment results were collated retrospectively. Of the four patients one had a transitional cell carcinoma of the mid-penile urethra in stage pT2 G2. In two out of the four patients a squamous cell carcinoma (PEC) was present in the mid-penile urethra in stages pT2 G2 and pT2 G3, respectively, with concomitant carcinoma in situ (CIS). The fourth patient had a PEC of the fossa terminalis in stage pT2 G2. Initially all patients underwent a penis-preserving resection. In one case, despite an initial R0 resection a local recurrence occurred and a complete penectomy was performed. Irradiation and lymphadenectomy were not carried out. At a mean follow-up of 37 months all patients are currently in complete remission. Primary penile urethral cancer can be treated by a penis-preserving operation. Close follow-up is essential because recurrence can arise despite an initial R0 resection.

  4. Penile duplication and two anal openings; report of a very rare case.

    Bakheet, Mohamed Abdel Al M; Refaei, Mohammad

    2012-03-01

    Penile duplication (diphallus) is an extremely rare disorder. It is almost always associated with other malformations like double bladder, exstrophy of the cloacae, imperforate anus, duplication of the rectosigmoid and vertebral deformities. Meanwhile anal canal duplication, the most distal and least common duplication of the digestive tube and is a very rare congenital malformation. A 21 days old Egyptian neonate is reported with complete penile duplication and two scrotums with each one carrying two palpable testes. Both penises have normal shaft with normally located meatus. Clear urine voids from both meati spontaneously. The child had also a fold of redundant skin about 4×5 cm at the anal region in which two separate anal openings are present. In rectal examination we found two normal anuses passing stool spontaneously. Ascending (voiding) cystourethrography revealed two penises with two separate meatuses and one bladder from which the two urethras go out separately. Intravenous pyelogram (IVP) revealed two normal kidneys and ureters. Barium study revealed duplication of rectum and colon, otherwise normal GIT. In our review of the literature, we did not come across any other case of this variety of the penile duplication and congenital presence of two anuses. Unfortunately the patient expired before any surgical correction.

    2018-05-01

    Full Text Available Bladder exstrophy is a rare developmental anomaly. Four principle variants of bladder exstrophy have been described and they themselves are rarer than the bladder exstrophy. Authors describe the management of a case of pseudoexstrophy type of variant in a 9 month old male child with penile duplication with torsion and coronal hypospadias. The rectal fascial defect was repaired without osteotomy as the distance between two pubic bones was <4 cm (3.1 cm. Genital reconstruction with excision of duplicate atrophic penile shaft and repair of coronal hypospadias with detorsion of the functional penile shaft could be accomplished. The patient had good outcome in terms of cosmesis and urinary stream. Total of 18 cases of the pseudoexstrophy have been described till date. Pseudoexstrophy of bladder is a very rare condition and can simultaneously present with other defects like omphalocele, anorectal malformations, pouch colon, multiple or solitary urogenital anomalies. The principles of correction though remain same with correction of abdominal wall defect with or without osteotomy depending upon severity of pubic diastasis. Other anomalies can undergo treatment as per standard protocol.

  7. Suprapubic cystostomy for the management of urethral injuries during penile prosthesis implantation.

    Anele, Uzoma A; Le, Brian V; Burnett, Arthur L

    2014-12-01

    Urethral injury is an uncommon surgical complication of penile prosthesis (PP) surgery. Conventional dogma requires abortion of the procedure if the adjacent corporal body is involved or delayed implantation to avert device infection associated with urinary extravasation. Besides the setback of the aborted surgery, this management approach also presents the possible difficulty of encountering corporal fibrosis at the time of reoperation. We report an approach using primary urethral repair and temporary suprapubic cystostomy for the management of incidental urethral injuries in a cohort of patients allowing for successful completion of unaborted PP implantation. We performed a retrospective analysis of all patients receiving PPs from 1990 to 2014 in which incidental urethral injuries were repaired and PP implantation was completed with suprapubic cystostomy (suprapubic tube [SPT] insertion). After allowing for urethral healing and urinary diversion via SPT for 4-8 weeks, the PP was activated. Successful management was determined by the absence of perioperative complications within 6 months of implantation. We identified four cases, all receiving inflatable PPs, managed with temporary suprapubic cystostomy. These patients sustained urethral injuries during corporal dissection (one patient), corporal dilation (one patient), and penile straightening (two patients). All patients were managed safely and successfully. Primary urethral repair followed by temporary suprapubic cystostomy offers a surgical approach to complete PP implantation successfully in patients who sustain urethral injury complications, particularly for complex PP surgeries.

Nonetheless, questions regarding ideal subatmospheric pressure levels, modes of action, and therapeutic duration of VED remain unanswered. Moreover, it remains unclear whether a hypoperfused zone or PO 2 gradient appears in the penis during VED therapy. To optimize a clinical VED protocol in penile rehabilitation, further research on the mechanism of VED, especially real-time PO 2 measurements in different parts of the penis, should be performed.

  9. Penile erection responses of Nigella sativa seed extract on isolated rat corpus cavernosum

    Aminyoto, M.; Ismail, S.

    2018-04-01

    Nigella sativa L. (NS) from Ranunculaceae family is known as black cumin in Indonesia. The seed has been used as an aphrodisiac in ethnobotanical studies and reported to have pharmacological activities such as antihypertensive through the relaxant effect of vascular smooth muscles but the direct effect to the blood vessels of the corpus cavernosum is still unknown. The purpose of this study was to examine the response of NS seed extract on penile erection in vitro. NS seeds were macerated in ethanol solvent for three days in room temperature and repeated for two times. Penile erection responses was assessed using isolated rat corpus cavernosum in Krebs-Henseleit solution, temperature 37°C, pH 7.4, aerated with carbogen gas. After acclimation, corpus cavernosum was contracted with a phenylephrine solution. Ethanolic extract of NS seeds or control solution were given after reaching the plateu phase of the highest contraction. This study showed that the contraction response of the corpus cavernosum decreased after addition of NS extract and this action was increased with the addition of the extract concentration. This study concluded that NS seed ethanol extract affects the penile erection response directly through the relaxation of blood vessels in the corpus cavernosum.

  10. A preliminary study of the sensory distribution of the penile dorsal and ventral nerves: implications for effective penile block for circumcision.

    Long, Ronan M

    2012-01-31

    OBJECTIVE: To determine the sensory innervation of the penis, as regional anaesthesia is often used either for postoperative analgesia or as the sole anaesthetic technique for circumcision. Since first described in 1978 the dorsal penile nerve block has become the standard technique, but some blocks are ineffective; a better understanding of the sensory innervation of the penis might improve the efficacy of the dorsal penile block technique. PATIENTS AND METHODS: In 13 men undergoing circumcision with local anaesthetic, cutaneous sensation was tested before and after infiltration of the dorsal aspect of the penis, and then again after infiltration of the ventral aspect. The area of anaesthesia was mapped using pin-prick sensation. RESULTS: Ten of the 13 patients showed a similar pattern of sensory distribution. After the dorsal block, the dorsal aspect of the shaft of the penis and glans penis became insensate. The ventral aspect of the shaft remained sensate up to and including the frenulum. After successful ventral infiltration all sensate areas became insensate and circumcision proceeded. In one case the frenulum and distal ventral foreskin was anaesthetized after the dorsal block and ventral infiltration was not required. No patient experienced pain during circumcision. CONCLUSION: For consistently successful regional anaesthesia of the foreskin in circumcision, a dorsal block must be used. This should be combined with ventral infiltration at the site of incision. This method will avoid inconsistencies and allow pain-free circumcision using local anaesthesia in most men.

    2015-08-01

    Some men with corrected hypospadias perceive their penile appearance to be abnormal, although health professionals consider these results satisfactory. The aim of this study was to investigate how relevant women consider single aspects of penile appearance to be. Moreover, we studied whether women perceive hypospadias-affected surgically repaired genitals (HASRGs) to be as normal-looking as circumcised genitals and identified the most relevant predictors that influence whether a penis is perceived as normal. In this cross-sectional study, 105 women in different age groups (age range: 16-20, 25-30, and 40-45 years) completed a standardized questionnaire. Participants had to rate the importance of eight penile aspects and to indicate how normal they found the appearance of standardized photos of 10 HASRGs and of 10 circumcised genitals. Furthermore, they were asked about demographic characteristics and their sexuality. Results showed that women considered the position and shape of the meatus as the least important penile aspect. Furthermore, results showed that HASRGs with distal hypospadias were perceived to be as normal-looking as circumcised genitals, whereas genitals with more proximal hypospadias were perceived as significantly less normal. However, the difference need not be considered clinically relevant, as the effect size was small. Observer-related predictors of a more positive perception of HASRGs were higher age, higher sexual interest, and perceiving the general cosmetic penile appearance as more important and penile length as less important. Overall, women were found to consider the "position and shape of the meatus" as the least important penile aspect. These findings may stimulate reflections regarding the relevance of surgical correction of the meatus in minor forms of hypospadias. In addition, this study indicates that women perceived genitals of men with distal operated hypospadias (which represents the majority of hypospadias) to be as normal as

    Hydrogen sulfide (H2S) is an endogenous gasotransmitter. The levels of H2S-generating enzyme expression and endogenous H2S production in diabetic rats with erectile dysfunction (ED) remain unknown. The aim of this study was to investigate the expression of the H2S-generating enzymes and endogenous production of H2S in penile tissues of diabetic ED rats. Experimental rats were randomly divided into normal control group, apomorphine (APO)-positive group and APO-negative group. Primary rat corpus cavernosum smooth muscle cells (CCSMCs) and aortic endothelial cells (AECs) were isolated and cultured in vitro under 3 different conditions: normal glucose (NG) condition, high glucose (HG) condition, and osmotic control (OC) condition. Erectile function; H2S concentrations in plasma or penile tissues; expression of H2S-generating enzymes and endogenous H2S production in penile tissues, CCSMCs, and AECs. Erectile function was significantly decreasedin the APO-negative group. In addition to significantly decreased expression of cysteine aminotransferase (CAT), d-amino acid oxidase (DAO), and 3-mercaptopyruvate sulfurtransferase (3-MST), the H2S concentrations in plasma and penile tissues and endogenous H2S production were significantly decreased in the APO-negative group. Endogenous H2S production by cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) decreased to the same levels in the APO-negative and APO-positive groups as that in the normal control group. However, CBS and CSE expression remained unchanged in the 3 groups. Under HG conditions, H2S-generating enzyme expression in AECs did not change, while CAT, DAO, and 3-MST expression in CCSMCs was significantly decreased. In both cell types, H2S production by these enzymes was decreased in the HG group. Endogenous H2S production was significantly decreased in the diabetic ED rats' penile tissues due to downregulated expression of the CAT/3-MST and DAO/3-MST pathways and low activities of CBS and CSE

    Massive bone marrow necrosis was seen in a 42-year-old male with acute leukemia. In December, 1988, on admission, laboratory data revealed pancytopenia and a high level of serum LDH and ALKP. Bone marrow aspiration resulted in dry-tap and showed bone marrow necrosis in the bone marrow biopsy specimen. A bone marrow scintigraphy with 111In faintly visualized the bone marrow but visualized area was expanded in the extremities compared with normal subjects. The second bone marrow biopsy showed proliferation of blasts. In the middle of March, blasts began to appear in peripheral blood. The blasts were cytochemically negative for POX, Es, PAS, AcP, TdT and had surface markers CD3-, CD19-, CD33-, CD13-, LCA-, HLA-DR-. Even by investigation on rearrangement of the immunoglobulin heavy chain region, an origin of the blasts could not be determined. In April, the number of blasts in peripheral blood increased and hepatosplenomegaly developed rapidly. Therefore, he was put on the chemotherapy with vincristine and prednisolone, but he died of cerebral hemorrhage. The autopsy revealed widespread bone marrow necrosis. It has rarely been reported that massive bone marrow necrosis is found prior to the occurrence of acute unclassified leukemia.

    1983-04-01

    The authors discussed the developing process of delayed radiation necrosis of the brain from the case of a 42-year-old female who developed intracranial hypertension and left hemiparesis 5 and a half years after radiotherapy for pituitary adenoma. The initial sign of radiation necrosis was from a CT scan taken 3 and a half years after radiotherapy showing an irregular low density lesion in the right temporal lobe. CT scan 2 years later demonstrated displacement of the midline structures to the left and a larger low density lesion with partially high density in the right MCA territory that was enhanced with intravenous contrast medium. Recovery after a right temporal lobectomy and administration of steroid hormone were uneventful. Eight months later there were no signs of raised intracranial pressure nor of neurological deficits. Tissues obtained from the right temporal lobe at lobectomy revealed the characteristic changes of delayed radiation necrosis; a mixture of fresh, recent, and old vascular lesions in the same specimen. From these findings, it was speculated that delayed radiation necrosis might initially occur within several years after radiotherapy and might gradually take a progressive and extended course, even in cases whose clinical symptoms develop much later.

  19. Clinical and CT imaging features of abdominal fat necrosis

    Zhao Jinkun; Bai Renju

    2013-01-01

    Fat necrosis is a common pathological change at abdominal cross-sectional imaging, and it may cause abdominal pain, mimic pathological change of acute abdomen, or be asymptomatic and accompany other pathophysiologic processes. Fat necrosis is actually the result of steatosis by metabolism or mechanical injury. Common processes that are present in fat necrosis include epiploic appendagitis, infarction of the greater omentum, pancreatitis, and fat necrosis related to trauma or ischemia. As a common fat disease, fat necrosis should be known by clinicians and radiologists. Main content of this text is the clinical symptoms and CT findings of belly fat necrosis and related diseases.

    To investigate effectiveness of advanced skin flap and V-shaped ventral incision along the root of penile shaft for concealed penis in children. Between July 2007 and January 2015, 121 boys with concealed penis were treated with advanced skin flap and V-shaped ventral incision along the root of penile shaft. The age varied from 18 months to 13 years (mean, 7.2 years). Repair was based on a vertical incision in median raphe, complete degloving of penis and tacking its base to the dermis of the skin. Advanced skin flap and a V-shaped ventral incision along the root of penile shaft were used to cover the penile shaft. The operation time ranged from 60 to 100 minutes (mean, 75 minutes). Disruption of wound occurred in 1 case, and was cured after dressing change; and primary healing of incision was obtained in the others. The follow-up period ranged from 3 months to 7 years (median, 24 months). All patients achieved good to excellent cosmetic results with a low incidence of complications. The results were satisfactory in exposure of penis and prepuce appearance. No obvious scar was observed. The penis had similar appearance to that after prepuce circumcision. A combination of advanced skin flap and V-shaped ventral incision along the root of penile shaft is a simple, safe, and effective procedure for concealed penis with a similar appearance result to the prepuce circumcision.

    The aim of this study is to analyze post pubertal results of pre pubertal tunica albuginea plication with non-absorbable sutures in the correction of CPC. The files of patients who underwent tunica albuginea plication without incision (dorsal/lateral) were retrospectively reviewed. Patients younger than 13 years of age at the time of operation and older than 14 years of age in November 2015 were included. Patients with a penile curvature of less than 30 degrees & more than 45 degrees and penile/urethral anomalies were excluded. All of the patients underwent surgery followed by circumcision. The mean age of patients at the time of the operation was 9.7 years (range, 6-13 years). The mean degree of ventral penile curvature measured during the operation was 39 degrees while it was 41 degrees in the lateral curvatures. All of the patients were curvature-free at the end of the operation. At the time of the follow-up examination, the mean age was 16.7 years (range, 14-25 years). Six patients had a straight (0-10 degrees) penis during erection and seven patients had recurrent penile curvatures ranging from 30 to 50 degrees. Pre pubertal tunica albuginea plication of congenital penile curvature (30-45 degrees) with non-absorbable sutures performed without incision is a minimal invasive method especially when performed during circumcision. However, recurrence might be observed in half of the patients after puberty. Copyright® by the International Brazilian Journal of Urology.

    Full Text Available Abstract Background Penile cancer is an uncommon malignancy with an incidence of 1 per 100,000. Conservative and radical treatments can be disfiguring and may have an impact on sexual function, quality of life (QOL, social interactions, self-image and self-esteem. Knowledge of how this disease affects patients is paramount to developing a global, multi-disciplinary approach to treatment. Methods A Medline/PubMed literature search was conducted using the terms "sexual function penis cancer"; "quality of life penis cancer" and "psychological effects penis cancer" from 1985 to 2008. Articles containing quantitative data on QOL, sexual function or psychological well-being were included. Results 128 patients from 6 studies were included. 5 studies contained retrospective data whilst 1 study collected prospective data on erectile function. In the 6 studies 13 different quantitative tools were used to assess psychological well-being, QOL and sexual function. The General Health Questionnaire (GHQ showed impaired well-being in up to 40% in 2 studies. Patients undergoing more mutilating treatments were more likely to have impaired well-being. The Hospital Anxiety and Depression Score (HADS demonstrated pathological anxiety up to 31% in 2 studies. 1 study used the Diagnostic and Statistical Manual of Mental Disorders of psychiatric illness (DSM III-R with 53% exhibiting mental illness, 25% avoidance behaviour and 40% impaired well-being. 12/30 suffered from post-traumatic stress disorder.

    Recent research developments have revealed that caspase-dependent apoptosis is not the sole form of regulated cell death. Caspase-independent, but genetically regulated, forms of cell death include pyroptosis, necroptosis, parthanatos, and the recently discovered ferroptosis and autosis. Importantly, regulated necrosis can be modulated by small molecule inhibitors/activators, confirming the cell autonomous mechanism of these forms of cell death. The success of small molecule-mediated manipulation of regulated necrosis has produced great changes in the field of cell death research, and has also brought about significant changes in the fields of pharmacology as well as toxicology. In this review, we intend to summarize the modes of regulated cell death other than apoptosis, and discuss their implications in toxicology. Copyright © 2015 Elsevier Ireland Ltd.

    2011-01-01

    Full Text Available Introduction. Necrosis of the rectum is an uncommon finding due to abundant collateral vasculature. Its management remains challenging, without clear consensus in the literature. Case Report. We describe a case of a 53-year-old woman with multiple medical comorbidities that presented in septic shock and hematochezia. Colonoscopy revealed ischemic colitis. Conservative management was instituted. At two weeks, she presented evidence of peritonitis. Exploratory laparotomy revealed extensive necrosis of the left colon and rectum. Due to dense inflammation, resection was deemed unsafe. Therefore, a transverse ostomy with mucosal fistula was preformed. Multiple drains were left in place. The patient healed uneventfully. Conclusion. This case illustrates that, if extensive dissection of the distal colon and rectum is unsafe due to the patient's critical condition or technical feasibility, then a diverting ostomy of the proximal viable bowel along with a mucus fistula and good drainage of the abdomen represents an acceptable alternative.

    Full Text Available Osteomyelitis is designated to a variety of bone diseases having inflammation as a common denominator. Persistent infection progresses to inflammation of marrow space, haversian system and periostium of affected region. Thrombosis of endothelial vessels cause necrosis and sequestrum formation. Both pyogenic and nonpyogenic infections of jaw lead to this condition. Immunosuppressed patients are more prone to mycelial infections, whereas their occurrence in immunocompetent individuals are highly unusual.

    Avascular necrosis of the femoral head in adults is not common, but not too rare diseases. In orthopedic practice, it is one of the diseases that are causing implantation of hip replacement at a relatively early age. In the early detection and initiation of therapy can delay the implantation of prosthesis for several years, which is certainly more convenient for the patient and beneficial. This article is intended to acquaint the reader with the basic diagnostic procedures and therapy.

    2018-04-01

    Intraoperative urethral injury is an uncommon event during the placement of a penile prosthesis, and alternative management strategies have been proposed with continuation of implantation after urethral injury. To evaluate surgeon practices in the management of intraoperative urethral injury. An online survey was sent to the society listservs of the Genitourinary Reconstructive Surgeons (GURS) and the Sexual Medicine Society of North America (SMSNA). Physicians were queried on their fellowship training, experience with penile prosthesis implantation, and management of urethral injuries during prosthesis placement. The response data were analyzed using SAS 9.4 (SAS Institute, Cary, NC, USA). The χ 2 test and Fisher exact test were used to determine associations between variables. Survey responses. 131 survey responses were analyzed. Of the responders, 41.2% were GURS fellowship trained, 19.1% were SMSNA trained, 30.5% were non-fellowship trained, and 9.2% were trained in other fellowships. 25.4% of participants performed more than 50 implantations per year, 37.7% performed 20 to 50 per year, and 36.9% performed fewer than 20 per year. Urethral injury during prosthesis implantation was uncommon, with 26.2% reporting 0 injury, 58.5% reporting 1 to 3 injuries, and 15.4% reporting more than 3 career injuries. Injuries were most commonly encountered during corporal dilation (71.1%) compared with corporal exposure (12.5%) or penile straightening maneuvers (7.0%). There was no statistically significant difference with aborting or continuing implantation among GURS-trained, SMSNA-trained, other fellowship-trained, and non-fellowship-trained surgeons. Of all responders, 55% would abort the procedure after distal urethral injury, whereas 45% would continue the procedure with unilateral or bilateral insertion of cylinders. Patient factors that increased likelihood of terminating the procedure in the case of urethral injury included immunosuppression, spinal cord injury, and

    2018-02-17

    Since the use of antibiotics, bladder necrosis has become a rare condition. We report a case of bladder necrosis in a 90-year-old man following urinary retention. After insertion of a transurethral catheter (TUC), 2 L of urine was evacuated. In the following days, the TUC became intermittently blocked. Adequate bladder drainage could not be obtained despite intensive rinsing and placement of a suprapubic catheter. On surgical exploration necrosis of almost the entire bladder wall, except for the trigone, was encountered. Surgical debridement of the non-viable bladder wall without opening the abdominal cavity was conducted, and a TUC was placed in the Retzius cavity to ensure evacuation of urine. Since the patient was haemodynamically unstable, construction of a urinary diversion was waived and urinary drainage of the Retzius cavity by the TUC was accepted, resulting in adequate urinary drainage without compromising renal function. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

  14. Partial avascular necrosis after talar neck fracture.

    Babu, Nina; Schuberth, John M

    2010-09-01

    Recently, it has been shown that avascular necrosis of the talus can occur in only a portion of the talar body. There is little information regarding the geographic location of the avascular segment and the clinical significance of an incomplete avascular process. Seven patients with partial avascular necrosis after Hawkins type II or III fracture dislocations were evaluated with magnetic resonance scans. The precise anatomic location of the avascular segment was determined and assigned to a specific quadrant of the talar body. The operative exposure, incidence of collapse, and time to operative intervention was recorded. The avascular segment of the talar body was located predominantly in the anterior lateral and superior portion in six of the seven patients. Collapse occurred in three of the patients in the area of avascular process. There were no observable trends with regard to operative exposure, Hawkins classification, incidence of collapse, or time to operative intervention to the location of the avascular segment. Partial avascular necrosis can occur after fracture dislocation of the talus. The predominant location of the avascular segment was the anterior lateral and superior portion of the talar body. This observation corresponds to regional damage to the blood supply of the talus and may help clarify the pathogenesis of partial avascular process.

  15. The transverse penile pedicled flap urethroplasty: description of a simplified technique for the dissection of the Fascio-cutaneous flap.

    Shittu, O B; Sotunmbi, P T

    2015-06-01

    Urethroplasty is often required for long urethral strictures or urethral strictures that have recurred after repeated urethral dilatations or urethrotomy. The transvers penile skin pedicled flap is very versatile for the reconstruction of long urethral stricture. However the meticulous sharp dissection required to develop it takes a long time to do and may be associated with button hole injuries to the vascular pedicle and the penile skin. We describe a simplified technique of raising the flap which does not require sharp dissection and is very quick to accomplish. Technique involves using a circumcising distal penile shaft skin incision to de-glove the penis by blunt dissection. The skin substitute, adequate to give appropriate urethra calibre is similarly dissected bluntly along with its vascular pedicle from the proximal penile skin. The techniques used to facilitate successful blunt dissection are described. In 9 adults with long, multiple urethral strictures, the average time to develop the flap was 15 minutes and complication have been limited to temporary urethro-cutaneous fistula at the ventral part of the circular skin closure. These fistulae closed on conservative treatment. No patient suffered button-hole injuries to either the vascular pedicle or the penile skin. This modification to the standard sharp dissection is very quick to accomplish. It also avoids the creation of button-hole injuries to either the vascular pedicle or the penile skin. It should make the use of this versatile flap more attractive in the reconstruction of long urethral strictures in those who may wish to use this option for reconstruction of long urethral strictures.

    Full Text Available Background: Penile cancer is a rare disease in Colombia; in Cali, it represents 0.7% of all cancers. Penile cancer has been associated with old age, bad hygiene, smoking and lack of circumcision. This study aimed to describe the sociodemographic and clinical characteristics of patients with penile cancer who consulted to a tertiary referral hospital. Methods: A case series of all penile cancer cases at a reference institution in Cali during 2001-2010. Socioeconomic, demographic and clinical features of patients were described, and bivariate analyses were carried out. Results: There were 46 penile cancer cases. The average age was 60 ± 16.9 years. The main reason for consultation was an exophytic mass on the penis (75.0%. The most common location was the glans (69.6%, and the more frequent histology type was the squamous cell carcinoma (95.7%. With regard to risk factors, 65.5% of the patients had history of smoking and 90.9% did not have circumcision. Patients who underwent radical amputation had higher rates of positive nodes (55% vs. 13.5%, p=0.015 and ulcerative lesions (77.8% vs. 29.7%, p=0.018 than those who did not have the procedure done. Recurrence was associated with the presence of lymphadenopathy (p=0.02 and history of circumcision (p=0.015. Conclusion: Most of the patients with penile cancer found in this study had old age, history of tobacco use and lack of circumcision. Patients who presented with lymph node metastasis had to undergo more radical procedures and suffered a greater rate of recurrence compared with those without lymph node involvement. Robust studies to determine the risk factors among low-income populations are required.

    Coping with cancer, its treatment and recovery are dyadic processes within a relationship. Sexual dysfunctions and problems of penile cancer may add to the demands of coping. The prospective study aimed to describe the dyadic aspects of sexual well-being and life satisfaction before and 1 year after organ-sparing laser treatment of penile carcinoma. A consecutive series of 29 patients with penile carcinoma suitable for laser treatment were included together with their partners, median age 60 (37-73) years and 57 (30-72) years, respectively. Median length of relationship was 29 years (1-54 years). The participants completed structured interviews before treatment, at 6 months' and 12 months' follow-up. The interview addressed sexual activities, sexual functions, verbal (sexual) communication, and life satisfaction. Three well-validated instruments were included: Hospital Anxiety and Depression Scale, International Index of Erectile Function-5, and Life Satisfaction checklist, LiSat-11. The interviews contained the same questions for patients and partners at all three measuring points. There was a high level of within-couple agreement on sexual activities, sexual function, and life satisfaction before and after organ-sparring treatment. No significant differences between interview data at 6 and 12 months' follow-up occurred. Before treatment, sexual dysfunctions were common among men, especially decreased sexual interest and dyspareunia. At follow-up, increased sexual function was found, with the exception of erectile function and women's orgasm. A rather high proportion was being unsatisfactory sexually inactive. Few had an ongoing verbal (sexual) mutual communication. Couples with an active sexual life at follow-up showed coherence in high satisfaction with life as a whole. A high level of within-couple agreement concerning sexuality and life satisfaction points to the necessity of including an adequate sexological case history, counseling, and treatment for this

    Erectile dysfunction following radical prostatectomy (RP) is still a significant burden as a post-operative morbidity, despite advances in nerve-sparing techniques and penile (erectile function) rehabilitation (PR) programs. We assessed the effects of stimulation with the masturbation device "EGG" on enhancement of erectile response along with administration of phospho diesterase type 5 inhibitor. We also studied the change of self-esteem and motivation for continuation of PR after stimulation with EGG. Eight nonresponders for PDE5-I who underwent retropubic RP were enrolled. Patients' median age was 71.5 years old. No patients received adjuvant therapy for prostate cancer. The patients' erectile response in the penile rehabilitation session (masturbation) with PDE5-I+manual stimulation and PDE5-I+stimulation with EGG were evaluated by erection hardness score (EHS). Changes of self-esteem and motivation for penile rehabilitation were assessed by the self-esteem subscale of the Self-Esteem and Relationship (SEAR) questionnaire and one original question, respectively. PDE5-I + stimulation with EGG significantly enhanced EHS compared to PDE5-I+manual stimulation in the eight patients (p=0.027). Transformed score of self-esteem subscale score of SEAR questionnaire was significantly increased in the PR session with EGG compared to the PR session with manual stimulation (p=0.043). Six patients who showed a better erectile response with EGG retained motivation for continuation of PR. PDE5-I+stimulation with EGG improved the erectile response in post-RP patients. EGG as a masturbation device may have a potential for contribution to successful PR.

    Purpose: to retrospectively assess the outcome in patients treated with adjuvant radiotherapy for penile cancer. Patients and methods: between 1987 and 2006, 24 patients (median age, 62.7 years; range, 35.5-90.4 years) with squamous cell carcinoma of the penis (T1, n = 10; T2, n = 11; T3, n = 3) received megavoltage external radiotherapy (n = 22) or {sup 192}Ir high-dose-rate brachytherapy (n = 2) following total penectomy (n = 7), partial penectomy (n = 10), or local excision (n = 7); lymphadenectomy was performed in eight patients. In 14 patients, radiotherapy was delivered after incomplete tumor resection, and in 20 patients the planning target volume included the regional lymph nodes. Median total dose of external radiotherapy was 56 Gy/1.8-2 Gy (range, 50-60 Gy). Brachytherapy was given with a total dose of 45 Gy/3 Gy. Results: during a median follow-up of 58.4 months, penile or perineal recurrence was found in four patients giving a 5-year local control rate of 74.8%. Regional failure occurred in two patients. 5-year metastases-free survival and progression-free survival rates were 86.7% and 64.5%, respectively. Four patients died due to tumor progression. The actuarial 5-year cause-specific and overall survival rates were 84.3 and 56.6%, respectively. Conclusion: radiation therapy is a successful method of treatment for penile cancer in terms of local control and organ preservation after microscopically incomplete surgery. Radiotherapy of the regional lymph nodes might also be effective in preventing regional recurrence and can be considered in case of high-risk features and following excision of extensive lymph node involvement.

    Penile cancer is a rare malignancy, and few guidelines are available to define treatment paradigms. For greater understanding of the natural history of surgically treated penile cancer, we analyzed the experience at our institution. Using an institutional database, we identified 127 patients treated for squamous cell carcinoma of the penis from 1995-2011. Cancer-specific survival (CSS) was calculated using the Kaplan-Meier method. Survival data were compared using the log-rank test. The difference in risk of cancer-specific death by lymph node status and histological grade was determined by univariate Cox regression analysis. Five year CSS for pTis, pT1, pT2, and pT3/4 was 100%, 84% (95% CI 58%-95%), 54% (95% CI 33%-71%), and 54% (95% CI 25%-76%), respectively (p ≤ .005). Three year CSS for patients with N0, N+, and Nx disease was 90% (95% CI 47%-99%), 65% (95% CI 47%-79%), and 86% (95% CI 73%-93%), respectively (p = .03). The receipt of neoadjuvant chemotherapy did not change per 5 year period over the 16 years of our study. Median follow up was 2.8 years. Penile cancer patients with advanced disease had poor survival. Tumor stage and nodal status were significant predictors of CSS. Penis-sparing approaches may be considered for most patients; however, pathological stage and grade dictate the management and ultimate outcome. Further studies are necessary to clarify the benefits of chemotherapy in this disease.

  1. The Role of Hedgehog-Interacting Protein in Maintaining Cavernous Nerve Integrity and Adult Penile Morphology

    Angeloni, Nicholas L.; Bond, Christopher W.; Monsivais, Diana; Tang, Yi; Podlasek, Carol A.

    2010-01-01

    Introduction Sonic hedgehog (SHH) is an essential regulator of smooth muscle apoptosis in the penis that has significant clinical potential as a therapy to suppress post-prostatectomy apoptosis, an underlying cause of erectile dysfunction (ED). Thus an understanding of how SHH signaling is regulated in the adult penis is essential to move the field of ED research forward and to develop new treatment strategies. We propose that hedgehog-interacting protein (HIP), which has been shown to bind SHH protein and to play a role in SHH regulation during embryogenesis of other organs, is a critical regulator of SHH signaling, penile morphology, and apoptosis induction. Aims We have examined HIP signaling in the penis and cavernous nerve (CN) during postnatal differentiation of the penis, in CN-injured, and a diabetic model of ED. Methods HIP localization/abundance and RNA abundance were examined by immunohistochemical (IHC) analysis and real-time reverse transcriptase-polymerase chain reaction (RT-PCR) in Sprague-Dawley rats between the ages of 7 and 92 days old, in CN-injured Sprague-Dawley rats and in BioBreeding/Worcester diabetic rats. HIP signaling was perturbed in the pelvic ganglia and in the penis and TUNEL assay was performed in the penis. CN tie, lidocaine, and anti-kinesin experiments were performed to examine HIP signaling in the CN and penis. Results In this study we are the first to demonstrate that HIP undergoes anterograde transport to the penis via the CN, that HIP perturbation in the pelvic ganglia or the penis induces apoptosis, and that HIP plays a role in maintaining CN integrity, penile morphology, and SHH abundance. Conclusions These studies are significant because they show HIP involvement in cross-talk (signaling) between the pelvic ganglia and penis, which is integral for maintenance of penile morphology and they suggest a mechanism of how nerves may regulate target organ morphology and function.

    Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. Prosthesis replacement has become an accepted procedure in the event of device malfunction or complications, but to our knowledge, there are no data regarding the impact of implant replacement on patients and partner satisfaction. The aim of our study was to assess and to compare the level of satisfaction, with a first or second penile prosthesis implantation (PPI), in men with refractory erectile dysfunction and their partners. A survey study based on a five-item questionnaire was carried out at our center between January 1999 and January 2012. The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after PPI. Of the 190 eligible patients, 149 (78%) completed the survey (110 underwent a first implant and 39 a reimplant). Seventy-nine percent of first-time implanted patients and 80% of the reimplanted patients (P > 0.05; not significant [ns]) reported satisfactory sexual intercourse (very or moderately satisfied), while 74% and 80% of their partners reported satisfactory intercourses, respectively (P > 0.05; ns). Overall, 73.7% of first implants and 70% of second implants reported that they would undergo the procedure again if the PPI failed (P > 0.05; ns). With regards to cosmetic aspects, 13% of the first implants' and 15% of second implants' partners reported either penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of first implants and 1% of reimplanted patients expressed difficulty in manipulating the device. PPI is successful in returning the ability for satisfactory sexual intercourse to both first implant and reimplanted patients and their respective partners. © 2015 International Society for Sexual Medicine.

    Full Text Available Purpose We studied the use of magnetic resonance imaging in the diagnosis of penile fracture. Materials and Methods Between 1997 and 2012, fifteen patients (age range 17-48 years, mean age 37 years with suspected penile fracture underwent MRI examinations. Ten patients were injured during sexual intercourse, whereas four patients were traumatized by non-physiological bending of the penis during self manupilation, one patient was traumatized falling from the bed. Investigations were performed with 1.5T MR unit. With the patient in the supine position, the penis was taped against the abdominal wall and surface coil was placed on the penis. All patients were studied with axial, coronal, sagittal precontrast and postcontrast T1-weighted TSE(TR/TE:538/13 msn and T2-weighted TSE(5290/110 msn sequences. All patient underwent surgical exploration. The follow-up ranged from 3 months to 72 months. Clinically all patients showed normal healing process without complications. In 11 patients a shortening and thickening of tunica albuginea was observed. Three patients have post traumatic erectil disfunction. Results In all patient corpus cavernosum fractures were clearly depicted on a discontinuity of the low signal intensity of tunica albuginea. These findings were most evident on T1WI and also depicted on T2W sequences. Images obtained shortly after contrast medium administration showed considerable enhancement only in rupture site. Subcutaneous extratunical haematoma in all patients were also recognizable on T2 WI. MRI findings were confirmed at surgery. Conclusions Magnetic resonance imaging is of great value for the diagnosis of penile fracture. Furthermore this method is well suited for visualising the post-operative healing process

    We report on a 6-year old child with a penile injury resulting in the inclusion of a pellet in the cavernous body, by a fortuitous shot. Conservative approach with elective extraction of the bullet and cavernous body repair led to a satisfactory result, in better anatomic conditions. The patient did not have any perioperative complication. Accidents by air weapons are particularly important in children, because these weapons are erroneously considered as toys. Air gun injuries to head, neck and thorax have been often published, but these injuries are rare in the chidren genitourinary area.

  7. Traumatic Penile Pain: A Case of Dorsal Vein Thrombophlebitis after Intercourse

    Garry J. Kennebrew

    2018-01-01

    Full Text Available Dorsal Vein thrombosis, also known as Mondor’s disease of the penis, is a superficial thrombophlebitis first described in the literature by Falco in 1955. Mondor’s disease refers to a superficial thrombophlebitis of any locale. Diagnosis can be made clinically with palpation of a mobile, cord-like thickening on dorsum of penis without associated evidence of inflammation, infection, or dermatologic changes. Bedside ultrasonography with color Doppler can aid in the diagnosis of penile thrombophlebitis by revealing a noncompressible superficial vessel with normal surrounding flow. The following case presentation details the etiology, diagnosis, and management of a particularly rare disease process.

    To establish normative data for stretched penile length (SPL) in term male neonates born in Tamil Nadu. All live term male neonates delivered in a hospital during a given period were included. SPL was measured from the pubic ramus to the tip of the glans. Two consecutive measurements were taken and average was recorded. The mean SPL observed in our study was 2.83 ± 0.49 cm. This study helps establish normative values for SPL in neonates of Tamil Nadu origin.

  9. Contemporary Role of Radiotherapy in the Management of Primary Penile Tumors and Metastatic Disease.

    Crook, Juanita

    2016-11-01

    Squamous cell cancer of the penis is a radiocurable malignancy all too often managed solely by partial or total penectomy. Effective management of the primary tumor while preserving penile morphology and function is a priority. External radiotherapy and brachytherapy have a role to play in the definitive management of the primary tumor. Surgical nodal staging remains a cornerstone of management because it is the strongest predictor of survival, and inguinal status determines pelvic management. Postoperative radiotherapy of the regional nodes for high-risk pathology is indicated. Chemoradiotherapy should be considered as neoadjuvant treatment for unresectable nodes or as definitive management. Copyright © 2016 Elsevier Inc. All rights reserved.

    Penile strangulation by metal ring is a rare urological emergency situation which requires urgent decompression of the penis to avoid adverse effect. It is usually associated with an attempt to improve sexual act and/or to prolong erection. But sometimes, cutting of the ring to decompress the penis safely is a very difficult task particularly when the strangulating object is a hard metal object as in our case. Here, we present a case which was managed by cutting in a novel way with the help of dental micromotor with wheel shape bur. PMID:28216935

    Arvind Goyal

    2001-01-01

    Full Text Available Penile gangrene associated with chronic renal failure, is a rare entity. Patients usually have associated diseases like diabetes, hypertension. Gangrene occurs because the dystrophic calcific infiltration causes huninal obstruction. This is an accompaniment of generalized soft tissue calcification and bony abnormality resulting. from secondary hyperparathyroidism. Calcium phosphate product exceeds plasma solubility causing precipitation of calcium phosphate. Medical treatment may maintain the product below precipitation levels. Mortality in these patients remains high due to the severity of the associated systemic illnesses. Conservative surgical treatment is advocated in view of short life span.

  14. Ketoconazole attenuates radiation-induction of tumor necrosis factor

    1994-07-01

    Previous work has demonstrated that inhibitors of phospholipase A2 attenuate ionizing radiation-induced arachidonic acid production, protein kinase C activation, and prevent subsequent induction of the tumor necrosis factor gene. Because arachidonic acid contributes to radiation-induced tumor necrosis factor expression, the authors analyzed the effects of agents which alter arachidonate metabolism on the regulation of this gene. Phospholipase A2 inhibitors quinicrine, bromphenyl bromide, and pentoxyfylline or the inhibitor of lipoxygenase (ketoconazole) or the inhibitor of cycloxygenase (indomethacine) were added to cell culture 1 h prior to irradiation. Radiation-induced tumor necrosis factor gene expression was attenuated by each of the phospholipase A2 inhibitors (quinicrine, bromphenylbromide, and pentoxyfylline). Furthermore, ketoconazole attenuated X ray induced tumor necrosis factor gene expression. Conversely, indomethacin enhanced tumor necrosis factor expression following irradiation. The finding that radiation-induced tumor necrosis factor gene expression was attenuated by ketoconazole suggests that the lipoxygenase pathway participates in signal transduction preceding tumor necrosis factor induction. Enhancement of tumor necrosis factor expression by indomethacin following irradiation suggests that prostaglandins produced by cyclooxygenase act as negative regulators of tumor necrosis factor expression. Inhibitors of tumor necrosis factor induction ameliorate acute and subacute sequelae of radiotherapy. The authors propose therefore, that ketoconazole may reduce acute radiation sequelae such as mucositis and esophagitis through a reduction in tumor necrosis factor induction or inhibition of phospholipase A2 in addition to its antifungal activity. 25 refs., 2 figs.

    Magnetic resonance (MR) images of 70 joints were reviewed in 38 patients with avascular necrosis of the knee or hip joint, whose ages ranged from 19 to 62 years with an average of 41 years. According to causes, steroid induced avascular necrosis was the commonest, accounting for 87% of cases. The remainer of the cases were alcoholic avascular necrosis (8%) and idiopathic avascular necrosis (5%). Steroid induced avascular necrosis was greatly different from idiopathic avascular necrosis in view of clinical manifestations, common sites, and complications of femur head necrosis. Idiopathic avascular necrosis was common in the central part of internal condyle and was confined to one joint. Steroid induced avascular necrosis was common in the posterior part of external condyle and was frequently associated with multiple necroses of the diaphysis. Seventy five percent of the cases were associated with avascular necrosis of the knee. The diagnostic accuracy of the other imaging modalities in avascular necrosis was low (33% for plain roentgenography and 50% for RI examination). Thus, MR was the imaging procedure of choice for detecting avascular necrotic lesions. (N.K.).

    To evaluate insulin-like growth factor-1 receptor (IGF1R) expression in penile cancer and its association with oncologic outcomes. Tissue microarrays were constructed from 53 patients treated at our institution. Expression of IGF1R was evaluated using a Her2-like scoring system. Overexpression was defined as 1+ or greater membranous staining. Association of IGF1R expression with pathologic features was assessed with comparative statistics, and association with local recurrence, progression to nodal or distance metastases, or death was assessed with Kaplan-Meier survival analysis and Cox proportional hazard regression models. Overall, IGF1R overexpression was seen in 33 (62%) cases. With a median follow-up of 27.8 months, IGF1R overexpression was associated with inferior progression-free survival (PFS) (P  =  .003). In a multivariable model controlling for grade, T stage, perineural invasion, and lymphovascular invasion, IGF1R expression was independently associated with disease progression (hazard ratio 2.3, 95% confidence interval 1.1-5.1, P  =  .03. Comparing patients without IGF1R overexpression to those with overexpression, 5-year PFS was 94.1% vs 45.8%. IGF1R overexpression was associated with inferior PFS in penile cancer. Drugs that target IGF1R and downstream messengers may have a therapeutic benefit in patients that exhibit IGF1R overexpression. Copyright © 2016 Elsevier Inc. All rights reserved.

    We analyzed the trends in presentation of squamous cell carcinoma (SCC) of the penis and determined the socioeconomic predictors for locally advanced (cT3-cT4) disease in the United States. The National Cancer Database was queried for patients with clinically nonmetastatic penile SCC and staging available from 1998 to 2012. Temporal trends per tumor stage were evaluated, and a multivariable logistic regression model was used to identify predictors for advanced presentation during the study period. A total of 5767 patients with stage ≤ T1-T2 (n = 5423) and T3-T4 (n = 344) disease were identified. Increasing trends were noted in all stages of penile SCC with a greater proportion of advanced cases over time (P = .001). Significant predictors of advanced presentation were age > 55 years, the presence of comorbidities, and Medicaid or no insurance (P guide targeted interventions in vulnerable populations.

  19. A Rare Urologic Emergency of Penile Strangulation with a Metallic Ring

    Hasan Hüseyin Tavukçu

    2017-03-01

    Full Text Available A 31-year-old man was presented to our emergency room in a distressed state with a heavy metallic ring 4 cm wide and 0.6 cm thick placed at the root of the penis for attempting masturbation. The ring was placed approximately 6 hours previously and the patient had tried several maneuvers using different tools to remove it. The patient suffered proximal penile strangulation with painful priapism. Under general anesthesia, multiple punctures to the glans penis and circumcision scar were made in order to aspirate entrapped blood and edema. After minimal regression of distal penile edema, we tried to cut the ring with metal cutters that orthopedicians use, but it was not successful. With a quite amount of lubricant, surgery string to keep the distal penis compressed, and the application of steady force to the ring, we were able to remove the metallic ring. The operation time was 2 hours without any complications. At 36 hours after the operation, the penis looked quite normal and the patient was discharged after 48 hours. The urethral catheter was removed at the first week after the operation. At the end of 12 months, there were no findings of urethral stricture and erectile dysfunction.

    2017-01-01

    Background The aim of this study was to use a three-dimensional (3D) visualization technology to illustrate and describe the anatomical features of the penile suspensory ligamentous system based on the Visible Human data sets and to explore the suspensory mechanism of the penis for the further improvement of the penis-lengthening surgery. Material/Methods Cross-sectional images retrieved from the first Chinese Visible Human (CVH-1), third Chinese Visible Human (CVH-3), and Visible Human Male (VHM) data sets were used to segment the suspensory ligamentous system and its adjacent structures. The magnetic resonance imaging (MRI) images of this system were studied and compared with those from the Visible Human data sets. The 3D models reconstructed from the Visible Human data sets were used to provide morphological features of the penile suspensory ligamentous system and its related structures. Results The fundiform ligament was a superficial, loose, fibro-fatty tissue which originated from Scarpa’s fascia superiorly and continued to the scrotal septum inferiorly. The suspensory ligament and arcuate pubic ligament were dense fibrous connective tissues which started from the pubic symphysis and terminated by attaching to the tunica albuginea of the corpora cavernosa. Furthermore, the arcuate pubic ligament attached to the inferior rami of the pubis laterally. Conclusions The 3D model based on Visible Human data sets can be used to clarify the anatomical features of the suspensory ligamentous system, thereby contributing to the improvement of penis-lengthening surgery.

    Over the past few decades, some principles in the treatment of penile cancer have changed fundamentally. While 15 years ago a negative surgical margin of at least 2 cm was considered mandatory, organ-sparing surgery permitting minimal negative surgical margins has a high priority nowadays. The current treatment principle requires as much organ preservation as possible and as much radicality as necessary. The implementation of organ-sparing and reconstructive surgical techniques has improved the quality of life of surviving patients. However, oncological and functional outcomes are still unsatisfactory. Alongside with adequate local treatment of the primary tumour, a consistent management of inguinal lymph nodes is of fundamental prognostic significance. In particular, clinically inconspicuous inguinal lymph nodes staged T1b and upwards need a surgical approach. Sentinel node biopsy, minimally-invasive surgical techniques and modified inguinal lymphadenectomy have reduced morbidity compared to conventional inguinal lymph node dissection. Multimodal treatment with surgery and chemotherapy is required in all patients with lymph node-positive disease; neoadjuvant chemotherapy has been established for patients with locally advanced lymph node disease, and adjuvant treatment after radical inguinal lymphadenectomy for lymph node-positive disease. An increasing understanding of the underlying tumour biology, in particular the role of the human papilloma virus (HPV) and epidermal growth factor receptor (EGFR) status, has led to a new pathological classification and may further enhance treatment options. This review summarises current aspects in the therapeutic management of penile cancer. © Georg Thieme Verlag KG Stuttgart · New York.

    Thomas, A Z

    2011-02-01

    We sought to evaluate the extended long term functional outcome of the AMS700 three piece inflatable prosthesis in men with erectile dysfunction in a single urological department and assess our revision rates. Patients that underwent first-time insertion or revision of an AMS700 3 piece inflatable penile prosthesis between 1984-2007 were included. Data was obtained from medical records and long term follow up of patients was conducted by telephone interview. The medical records of 38 patients were available for review. Of these 38 men, 56 prostheses were inserted. The mean follow up was 8.4 years (101 months). The revision rate at 50 months postoperatively was 7\\/38 (18%). The overall revision rate was 18\\/38 (47%). The mean time to revision in these 18 patients was 72 months (12-156 months) after initial insertion of AMS700 penile prosthesis. This study highlights that with longer follow u revision rates markedly increase after 72 months.

    2015-09-01

    Full Text Available Objectives: The aim of our study was to report our experience with patients affected by Erectile Dysfunction (ED and undergoing penile prosthetic implantation (PPI in a single center by a single surgeon. Material and Methods: We retrospectively evaluated the clinical outcome of 500 patients (mean age: 51.5 years, range: 20-86 years affected by ED and referred to our private andrological center from January 1984 to December 2013 who underwent penile prosthesis implantation, including the reported level of patient satisfaction. Results: 182 silicone, 180 malleable, 18 monocomponent hydraulic and 120 multicomponents hydraulic prostheses were implanted by the same experienced surgeon. All patients were hospitalized for the procedure. All patients were evaluated immediately, 1 month (496 patients and, for the great majority, every year after implantation. One hundred twenty five patients were lost to follow-up. Twenty two patients underwent revision surgery for complications in the postoperative period. The most serious postoperative complications were mechanical problems (45 patients, 9.0% and infection (15 patients, 3%. Forty two (8.4% prostheses were explanted. Overall, 80% (400/500 of patients were able to have sexual intercourse and were fully satisfied with the results. Conclusions: In our experience prosthetic surgery should be considered a good solution for men affected by ED and not responsive to other therapeutic solutions. Prosthetic surgery can be performed not only in large public hospitals but also in smaller private facilities.

  4. A case of scrotal elephantiasis 30 years after treatment of penile carcinoma

    Horinaga, Minoru; Masuda, Takeshi; Jitsukawa, Seido [Urawa Municipal Hospital, Saitama (Japan)

    1998-11-01

    A 67-year-old man visited our hospital with complaints of scrotal swelling associated with occasional febrile episodes. Physical examination disclosed a huge scrotal mass, approximately the size of a child`s head, with numerous papillomatous lesions in its surface. His past medical history was significant in that he was diagnosed with penile carcinoma at the age of 35 years old and was treated with partial penectomy followed by radiation and chemotherapy at other hospital. During this admission tumor marker squamous cell carcinoma (SCC) and microbiological tests for microfilariae were both negative. Ultrasound (US), computed tomographic (CT) scan and magnetic resonance imaging (MRI) revealed markedly thickened scrotal skin and small hydrocele with no evidence of local recurrence of the previous penile carcinoma. A percutaneous cystostomy was created because of chronic urinary retention and possible urine extravasation into the scrotum. Histopathological examination of the biopsy specimen from the scrotal mass demonstrated lymphagiectasia consistent with elephantiasis of the scrotum. Surgical excision of this huge scrotal mass was performed in August 1997. The resected tissue weighted 1,400 g. Convalescene was uneventful. He subsequently underwent perineal urethrostomy in place of the suprapubic cystostomy. (author)

  6. Identification of a novel herpesvirus associated with a penile proliferative lesion in a beluga (Delphinapterus leucas).

    Bellehumeur, Christian; Lair, Stéphane; Romero, Carlos H; Provost, Chantale; Nielsen, Ole; Gagnon, Carl A

    2015-01-01

    The carcass of an adult male beluga (Delphinapterus leucas) was found beach cast in 2008 on the shore of the St. Lawrence Estuary at Rivière-Ouelle, Quebec, Canada. The carcass was transported to the Faculté de médecine vétérinaire of the Université de Montréal for postmortem examination. Aspiration pneumonia was the probable cause of death. Necropsy revealed a focal papilloma-like penile lesion, characterized by focal mucosal thickening with disorganization of the epithelial layers and lymphoplasmacytic infiltration. A pan-herpesvirus nested PCR assay on frozen tissue from the penile lesion was positive. The PCR product sequencing revealed a partial herpesvirus DNA polymerase (DPOL) gene sequence of 600 nucleotides. Its nearest nucleotide identity was with the partial DPOL gene of an alphaherpesvirus, bovine herpesvirus 5 (79.5% identity). It also shared high identity with several other marine mammal herpesviruses (50.2 to 77.3% identity). This new herpesvirus was tentatively named beluga whale herpesvirus (BWHV). Virus isolation was unsuccessful. The pathogenic potential of BWHV is unknown, but the evaluation of archived tissues suggests that the virus is endemic in the St. Lawrence Estuary beluga population.

    Penile corporoplasty is a well-established treatment method of congenital penile deviation (CPD). Anatomical results are good with only slight differences between surgical procedures used. The disease however has huge influence on young male quality of life. This issue is not well analyzed in the literature. The aim of the study was to evaluate quality of life of the patients affected with CPD before and after the surgical treatment Study population consisted of 107 patients with CPD referred for surgical management. Patients were evaluated with not only clinical assessment, but also by four questionnaires measuring various aspects of quality of life. They were: Short-Form Medical Outcomes, Sexual Quality of Life Questionnaire for Man, Beck Depression Inventory, and International Index of Erectile Function. Quality of life measurements showed deep decrease in the general quality of life, sexual performance, depression scale, as well as in physical and mental health in men with CPD. All these parameters were restored to normal after the successful surgical treatment with any method. CPD deeply decreases the quality of life of the affected men in many aspects. Surgical treatment is able to repair the anatomical deformity and as well as significantly restore the patients' psychosocial well-being. © 2015 International Society for Sexual Medicine.

    To investigate the effects of penile tourniquet (PT) application on bacterial adhesion to urothelium. Fifty-six rats were allocated into control group (CG), sham group (SG), PT group (PTG). No intervention was applied in CG. A 5mm-length urethral repair was performed in SG and PTG. In PTG, a 10-min duration of PT was applied during the procedure and the tissue oxygenation monitor was used to adjust the same degree of ischemia in all subjects. Samples were examined for wound healing parameters and tissue levels of inflammatory markers, eNOS, e-selectin, and ICAM-1antibodies. The adhesion of Escherichia coli to urothelium was investigated with in vitro adhesion assay. Inflammation was higher and wound healing was worse in SG than CG and in PTG in comparison to CG and SG (pcaused endothelial corruption and prevented cell proliferation in cell culture. The PT application does not improve wound healing and increases bacterial adhesion molecules in penile tissue. The in vitro assays showed that PT causes severe endothelial damage and inhibits endothelial cell proliferation. Copyright © 2017 Elsevier Inc. All rights reserved.

  9. Apoptosis and Necrosis in the Liver

    Guicciardi, Maria Eugenia; Malhi, Harmeet; Mott, Justin L.; Gores, Gregory J.

    2013-01-01

    Because of its unique function and anatomical location, the liver is exposed to a multitude of toxins and xenobiotics, including medications and alcohol, as well as to infection by hepatotropic viruses, and therefore, is highly susceptible to tissue injury. Cell death in the liver occurs mainly by apoptosis or necrosis, with apoptosis also being the physiologic route to eliminate damaged or infected cells and to maintain tissue homeostasis. Liver cells, especially hepatocytes and cholangiocytes, are particularly susceptible to death receptor-mediated apoptosis, given the ubiquitous expression of the death receptors in the organ. In a quite unique way, death receptor-induced apoptosis in these cells is mediated by both mitochondrial and lysosomal permeabilization. Signaling between the endoplasmic reticulum and the mitochondria promotes hepatocyte apoptosis in response to excessive free fatty acid generation during the metabolic syndrome. These cell death pathways are partially regulated by microRNAs. Necrosis in the liver is generally associated with acute injury (i.e., ischemia/reperfusion injury) and has been long considered an unregulated process. Recently, a new form of “programmed” necrosis (named necroptosis) has been described: the role of necroptosis in the liver has yet to be explored. However, the minimal expression of a key player in this process in the liver suggests this form of cell death may be uncommon in liver diseases. Because apoptosis is a key feature of so many diseases of the liver, therapeutic modulation of liver cell death holds promise. An updated overview of these concepts is given in this article.

  10. Delayed radiation necrosis in the optochiasmatic region

    Andoh, Takashi; Yokoyama, Kazutoshi; Kumagai, Morio

    1984-01-01

    Two cases with delayed radiation necrosis of the chiasmatic region following irradiation of the hypophysis for treatment of Cushing's disease were presented. Case 1 was a 36-year-old female who had reduction of visual acuity and bitemporal hemianopsia 2 years after 60 Co-irradiation therapy (total 8000 rads) for Cushing's disease. CT scans showed low density in the pituitary fossa and irregular contrast-enhanced suprasellar mass, and metrizamide CT cisternography revealed the pituitary fossa filled with contrast medium. From those findings, secondary empty sella syndrome was suspicious. Case 2 was a 35-year-old male who had progressive visual disturbance 3 years after 60 Co-irradiation therapy (total 9050 rads) for Cushing's disease. The right visual acuity was 0.05 and the left one was 0.1. Examination of visual field showed left homonymous hemianopsia. CT scans showed the contrast enhanced suprasellar mass extending to the right anterior thalamic region, and metrizamide CT cisternography detected secondary empty sella as same as that of Case 1. Authors reviewed and analyzed literatures of delayed radiation necrosis. The incidence of this condition was 4% to 9% and onset of the symptoms occured approximately 2 years after irradiation to hypophysis. Administration of steroid hormone and surgical treatment for the radiation necrosis involving the chiasmatic region were almost ineffective and also the prognosis of radionecrotic lesions involving the hypothalamus was very poor. Therefore, radiotherapy for hypophyseal region must be carried out by means of a rotation or arching technique in order to avoid this condition and further total dosage and its fractionation in radiation therapy should not exceed 6000 rads and 200 rads a day.

    Kinoshita, T.; Takahashi, S.; Ishii, K.; Higano, S.; Matsumoto, K.; Sakamoto, K.; Haginoya, K.; Iinuma, K.

    1996-01-01

    Serial MRI findings are described in two patients with Reye's syndrome, demonstrating diffuse cortical and white matter changes. In the acute stage, T2-weighted images showed subtle but definite laminar high signal and contrast-enhanced T1-weighted images laminar enhancement, along the entire cerebral cortex bilaterally. In the chronic stage, unenhanced T1-weighted images showed diffuse cortical laminar high signal. These characteristic MRI features seemed very similar to those of laminar cortical necrosis in hypoxic brain damage. MRI also displayed delayed white matter changes with cerebral atrophy. (orig.)

  16. Does penile rehabilitation have a role in the treatment of erectile dysfunction following radical prostatectomy? [version 1; referees: 2 approved

    Gideon Blecher

    2017-10-01

    Full Text Available In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post–radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

  17. Comparison of penile length at 6–24 months between children with unilateral cryptorchidism and a healthy normal cohort

    Full Text Available Purpose: Urologic diseases affected by testosterone can be associated with smaller penis size compared to the normal population. We sought to compare penile length in children with unilateral cryptorchidism and normative data from a cohort of healthy Korean boys. Materials and Methods: This study was performed in 259 Korean boys (212, normal cohort; 47, cryptorchidism aged 6–24 months, each of whom had been brought to an outpatient clinic at one of five tertiary hospitals (Gyeongsangnam-do Province between April 2014 and June 2015. Penile length was measured via stretched penile length (SPL and testicular size was measured using orchidometry (mL. Results: SPL in children with cryptorchidism was significantly shorter compared to a cohort of healthy Korean boys aged 6–24 months (3.7±0.5 cm and 4.3±0.8 cm, p<0.001, although there were no differences with regard to height, body weight and contralateral testicular size between the two groups. According to the stratified ages (6–12, 12–18, and 18–24 months, SPL in children with cryptorchidism was persistently shorter at their ages than those without. Conclusions: It might be that the penile length aged 6–24 months of children with unilateral cryptorchidism is shorter than that of a cohort of healthy Korean boys.

    Objectives: To evaluate the surgical outcome of tubularised incised plate urethroplasty and onlay island flap repair for mid and proximal penile hypospadias. Methods: The prospective study was conducted at the Bahawal Victoria Hospital, Bahawalpur from June 2011 to May 2013. A total of 60 patients with mid and proximal penile hypospadias in the age range of 02 to 06 years were included. Patients with hypospadias other than mid and proximal penile, with chordee and history of previous hypospadias repair were excluded. Patients were divided into two equal groups. Urethroplasty was done for group I and flap repair for group II. The follow-up period was 12-24 months. SPSS 16 was used for statistical analysis. Results: The mean duration of surgery was 62+-8.72 minutes for group I and 90+-11.25 minutes for group II (p<0.0001). In group I, only 03 (10.0%) patients had complications, while in group II, 09 (30.0%) patients developed complications (p=0.02). Cosmetic results were also excellent in group I compared to group II. Conclusion: Tubularised incised plate urethroplasty was better and superior than onlay island flap repair in terms of less operative time, complication rate and satisfactory cosmetic results for mid and proximal penile hypospadias.

In group I, only 03 (10.0%) patients had complications, while in group II, 09 (30.0%) patients developed complications (p=0.02). Cosmetic results were also excellent in group I compared to group II. Conclusion: Tubularised incised plate urethroplasty was better and superior than onlay island flap repair in terms of less operative time, complication rate and satisfactory cosmetic results for mid and proximal penile hypospadias.

    2009-01-01

    Full Text Available Objectives: To summarize the development of a novel non-invasive test to categorize voiding dysfunction in men complaining of lower urinary tract symptoms (LUTS - the penile cuff test. Methods: The test involves the controlled inflation of a penile cuff during micturition to interrupt voiding and hence estimate isovolumetric bladder pressure (p ves.isv . The validity, reliability, and clinical usefulness of the test were determined in a number of studies in men with LUTS. Results: The penile cuff test can be successfully performed in over 90% of men with LUTS. The reading of cuff pressure at flow interruption (p cuff.int gives a valid and reliable estimate of invasively-measured p ves.isv and when combined with the reading for maximum flow rate obtained during the test (Q max produces an accurate categorization of bladder outlet obstruction (BOO. Use of this categorization prior to treatment allows improved prediction of outcome from prostatectomy. Conclusion: The penile cuff test fulfils the criteria as a useful clinical measurement technique applicable to the diagnosis and treatment planning of men with LUTS.

  3. Penile venous surgery for treating erectile dysfunction: Past, present, and future perspectives with regard to new insights in venous anatomy

    Cheng-Hsing Hsieh

    2016-06-01

    Full Text Available In the physiologic model of normal erectile function, a healthy veno-occlusive mechanism is essential to initiate and maintain a rigid erection. The surgical treatment of patients with venous leakage, which is synonymous with corporoveno-occlusive dysfunction (CVOD, was based on the decreased venous outflow during the erection process. The initial reports of short-term results were promising, but the long-term benefits of penile venous ligation surgery were limited. Most clinical guideline panels concluded that surgeries performed in an attempt to limit the venous outflow of the penis were not recommended. Consequently, this surgery was nearly abandoned in most medical societies worldwide. These unfavorable postoperative outcomes seemed attributable to the indispensable usage of electrocautery and insufficient venous management, based on conventional penile venous anatomy. Advances in better understanding of human penile venous anatomy has enabled the development of refined penile venous stripping surgery. The thorough stripping surgery is an even more radical procedure, which is an even more radical procedure, and seems to be a viable option for the treatment of CVOD, however, there is still a need for further study with well-defined diagnostic criteria, and standardized patient and partner outcome assessment.

    It has been speculated for more than 2 decades whether there is a significance of adrenal corticosteroids, such as cortisol, in the process of normal male sexual function, especially in the control of sexual arousal and the penile erectile tissue. However, only few in vivo studies have been carried out up until now on the effects of cortisol on human male sexual performance and penile erection. In order to evaluate further the role of cortisol in male sexual activity, the present study was conducted to detect serum levels of cortisol in the systemic and cavernous blood taken during different penile conditions from healthy males. The effects of cortisol derivative prednisolone, catecholamine norepinephrine (NE) and the peptide endothelin-1 (ET-1) on isolated human corpus cavernosum (HCC) were investigated using the organ bath technique. Fifty-four healthy adult male subjects were exposed to erotic stimuli in order to elicit penile tumescence and rigidity. Whole blood was simultaneously aspirated from the corpus cavernosum and the cubital vein during different penile conditions. Serum levels of cortisol (microg/dl) were determined by means of a radioimmunoassay (ELISA). In the healthy volunteers, cortisol serum levels significantly decreased in the systemic circulation and the cavernous blood with increasing sexual arousal, when the flaccid penis became rigid. During detumescence, the mean cortisol level remained unaltered in the systemic circulation, whereas in the cavernous compartment, it was found to decrease further. Under all penile conditions, no significant differences were registered between cortisol levels in the systemic circulation and in the cavernous blood. Cumulative addition of NE and ET-1 (0.001-10 microM) induced contraction of isolated HCC strips, whereas the contractile response to prednisolone was negligible. Our results strongly suggest an inhibitory role for cortisol in the mechanism of male sexual response and behaviour. These properties are

    1999-01-01

    Full text: Avascular necrosis is frequently associated with sickle cell disease and other haemoglobinopathies. It is less commonly associated with Gaucher's disease. A case with multi-modality imaging is presented. A 33-year-old male patient presented with a 4-day history of severe right knee pain. He was a febrile with mild swelling of the right knee. A diagnosis of Gaucher's disease had been made by bone marrow biopsy on a clinical picture of hepatosplenomegaly and thrombocytopenia some years earlier. A radiograph of the knee demonstrated an Erlenmeyer flask deformity of the distal femur. A bone scan demonstrated reduced perfusion to the distal right femoral shaft and femoral condyles. Delayed images demonstrated decreased tracer uptake in the distal right femur extending to the right medial femoral condyle consistent with a vascular necrosis. An MRI of the thighs demonstrated lipid accumulation in the marrow space of both femora consistent with Gaucher's disease associated with changes of bone oedema in the metadiaphysis and epiphysis of the right femur. The patient was treated with supportive measures and made an uneventful recovery and is being commenced on enzyme replacement therapy (Algucerase)

    T1-weighted MR images of thirty-six hips in 25 patients with avascular necrosis of the femoral head were obtained two to five times during the course of 2 to 26 months. We investigated these MR images in the light of the chronological change and compared them with plain radiographs. MR images changes in 16 femoral head; in general, the abnormal low intensity area in the femoral head reduced in extent and the internal high intensity area became smaller of disappeared. Thirteen femoral heads among them became more flattened on plain radiographs in the same period. It is noted that four different zones are defined in the femoral head after bone necrosis takes place: the dead bone marrow, the dead marrow which still contains fat, the reactive interface and the hyperemic bone marrow. In T1-weighted MR images, the dead bone marrow, the reactive interface and the hyperemic bone marrow are demonstrated as low intensity area, while the dead marrow containing fat may remain high in intensity. On the basis of this knowledge of histopathology and MR images of this disease, we suggest that reduction of the abnormal low intensity area and disappearance of the internal high intensity area on MR images can be regarded as diminution of hyperemia in the living bone marrow and loss of fat in the dead bone marrow, respectively.

  7. Myoglobinaemia in relation to cardiac necrosis

    McComb, J M

    1981-01-01

    An evaluation of the usefulness of estimation of the serum myoglobin in the detection of myocardial necrosis was made in patients with suspected acute ischemic heart disease and in patients in whom elective cardiac catheterization was performed. Measurement of serum myoglobin, by radioimmunoassay, in patients admitted with suspected acute myocardial infarction, suggested that a raised serum myoglobin level was a sensitive indicator of myocardial necrosis. It also showed that the serum myoglobin rose to abnormal levels before the serum creatine kinase. A study of 70 consecutive patients confirmed that the serum myoglobin level is a sensitive indicator of acute myocardial infarction and showed that its sensitivity was greater, and its specificity similar to that of serum creatine kinase. This study allowed calculation of a predictive index for the diagnosis of acute myocardial infarction from the serum myoglobin and serum creatine kinase six hours after the onset of symptoms. The use of a single myoglobin measurement in 114 patients admitted to a coronary care unit was then studied. The proposition that myocardial damage might results from cardiac catheterization was investigated in 115 patients.

  8. Penile prosthesis surgery in out-patient setting: Effectiveness and costs in the “spending review” era

    2014-09-01

    Full Text Available Introduction: Penile implant patients are required to remain in the hospital after the operation for monitoring, antibiotic and analgesia administration. Cost containment, however, has resulted in the increased use of ambulatory surgery settings for many surgical procedures. Few studies have studied the feasibility of performing penile prosthesis insertion in an outpatient setting. The results are controversial and nowadays, in the most of centers that deal with prosthetic surgery, patients are still hospitalized. Aim: The aim of our investigation was to compare the feasibility of the performance as well as the complication profiles of penile implant surgery performed in an in-patient and an outpatient setting at a single center by a single surgeon. Methods: From January 2009 to June 2014, 50 patients of the same uro-andrological unit underwent penile prosthesis implantation performed by a single surgeon (N.M.. Twenty implantations were performed in an ambulatory day surgery setting. Main outcome measures: Effectiveness and costs of outpatient setting versus the in-patient setting of the penile prosthesis surgery. Results: There were some differences between the two groups in the intra-operative parameters, such as, operating time. Time lost from work was similar in both groups approximating 14 days. The mean number of analgesic pills ingested by the patients post-operatively was similar in both groups, averaging just under 25 pills per patient. There weren’t post-operative complications in the outpatient group. Cost were 17% less in outpatient clinic. Conclusions: The outpatient setting for this surgery is safe and effective even in patients with comorbidities or in case of secondary procedures. Costs are reduced by 17%.

  9. Pseudo-capsule “coffin effect”: How to prevent penile retraction after implant of three-piece inflatable prosthesis

    Enrico Caraceni

    2014-06-01

    Full Text Available Objective: Following three-component implantation of a penile prosthesis, some patients are dissatisfied with their penile length. This may be due to the procedure by itself or pre-existing risk factors or psychological reasons. We supposed that formation of a restricted pseudo-capsule due to a late prosthesis activation can inhibit later system expansion. We aimed to identify the presence or absence of penile retraction after implant and to prevent it by immediate prosthesis activation after implantation. Material and methods. Forty-six patients operated with three-piece inflatable penile prosthesis (AMS 700 CX o LGX were enrolled. In 27 patients prosthesis was first activated four weeks after surgery (NEA group and in 19 patients prosthesis was activated immediately after surgery (DEA group. Length and girth of the penis was evaluated before (in DEA group and after the surgical procedure. Results. The average post implant dorsal length of the erect penis in group NEA was found 3.28 cm shorter than in group with early activation (DEA. In DEA group there was no lenght difference between pre-operative stretching (14.57 cm and post operative erection (14.98 cm. When early activation was not performed, the clinical result was a smaller penis in erect phase. Conclusion. Reduced lenght of the penis after implantation can be caused by the presence of a pseudo-capsule that limits the elongation of the prosthesis and of the penis (“coffin effect”. Timing of first activation seems to be the key in order to prevent the risk of penile retraction after implantation. Early activation is identified as the best measure to maintain the length of the pre implant erect penis after the prosthetic hydraulic implant.

    Penile inversion vaginoplasty is considered to be the gold standard for gender reassignment surgery in transgender women. The use of additional full-thickness skin graft as neovaginal lining is controversial. Some believe that having extra penile skin for the vulva gives better aesthetic results. Others believe that it gives inferior functional results because of insensitivity and skin graft contraction. Transgender women undergoing penile inversion vaginoplasty were studied prospectively. The option to add full-thickness skin graft is offered in patients where the penile skin length lies between 7 and 12 cm. Neovaginal depth was measured at surgery and during follow-up (3, 13, 26, and 52 weeks postoperatively). Satisfaction with the aesthetic result, neovaginal depth, and dilation regimen during follow-up were recorded. Satisfaction, sexual function, and genital self-image were assessed using questionnaires. A total of 100 patients were included (32 with and 68 without additional full-thickness skin graft). Patient-reported aesthetic outcome, overall satisfaction with the neovagina, sexual function, and genital self-image were not significantly associated with surgical technique. The mean intraoperative neovaginal depth was 13.8 ± 1.4 cm. After 1 year, this was 11.5 ± 2.5 cm. The largest decline (-15 percent) in depth is observed in the first 3 postoperative weeks (p skin graft use, in penile inversion vaginoplasty. The additional use of full-thickness skin graft does not influence neovaginal shrinkage, nor does it affect the patient- and physician-reported aesthetic or functional outcome. Therapeutic, IV.

  11. Penile fracture: Retrospective analysis of our case history with long-term assessment of the erectile and sexological outcome

    Full Text Available Objectives: To review the cases of patients with suspected penile fracture and asses erectile and sexological outcomes. Materials and methods: from 1987 to 2013 presented to the Urology Clinic of Trieste and at the AIED of Pordenone a total of 41 cases that were divided into two groups according to the timing of treatment: 18 patients with anamnestic diagnosis of penile fracture treated nonimmediately and 23 patients treated immediately after the trauma. For all patients we evaluated the type of treatment adopted, the occurrence of complications and reoperations and the follow-up. The erectile function was also evaluated through the IIEF, as well as the psychological impact of the trauma on social and sex life, using a psycho- sexological questionnaire. Results: Among patients treated immediately after the trauma 14 were subjected to surgery. About a year after surgery, penile curvature was reported in 1 patient, pain in 3 patients, urinary disorders in 1 patient, while none reported erectile dysfunction (ED. Out of these, only 3 patients underwent reoperation. Among those treated conservatively 1 patient reported curvature, 1 patient reported pain and none reported ED. Among patients who were admitted at a later date, 14 reported curvature and 4 reported pain whereas urinary disorders were reported in 1 and ED in 4 patients. From a psychological point of view, the trauma caused in most cases a fear of new trauma and of repercussions on erectile function and sensitivity. Conclusions: The diagnosis is mainly clinical; however, radiological investigation is essential to confirm the diagnosis, assess the site and extent of the trauma and possible urethral involvement, so as to plan the most appropriate treatment. In addition, immediate treatment leads to better long-term results, with a lower incidence of ED and penile curvature. Psychologically, penile trauma intensifies the fear of reoccurrence; it decreases, however, with the passage of time.

    Pericardial fat necrosis is an infrequent cause of acute chest pain and this can mimic acute myocardial infarction and acute pericarditis. We describe here a patient with the magnetic resonance imaging (MRI) findings of pericardial fat necrosis and this was correlated with the computed tomography (CT) findings. The MRI findings may be helpful for distinguishing pericardial fat necrosis from other causes of acute chest pain and from the fat-containing tumors in the cardiophrenic space of the anterior mediastinum.

    2012-12-01

    Full Text Available Abstract Background Besides being a causative agent for genital warts and cervical cancer, human papillomavirus (HPV contributes to 40-85% of cases of anal, penile, vaginal and vulvar cancer and precancerous lesions. HPV types 16 & 18 in particular contribute to 74-93% of these cases. Overall the number of new cases of these four cancers may be relatively high implying notable health care cost to society. The aim of this study was to estimate the incidence and the health care sector costs of anal, penile, vaginal and vulvar cancer. Methods New anogenital cancer patients were identified from the Danish National Cancer Register using ICD-10 diagnosis codes. Resource use in the health care sector was estimated for the year prior to diagnosis, and for the first, second and third years after diagnosis. Hospital resource use was defined in terms of registered hospital contacts, using DRG (Diagnosis Related Groups and DAGS (Danish Outpatient Groups System charges as cost estimates for inpatient and outpatient contacts, respectively. Health care consumption by cancer patients diagnosed in 2004–2007 was compared with that by an age- and sex-matched cohort without cancer. Hospital costs attributable to four anogenital cancers were estimated using regression analysis. Results The annual incidence of anal cancer in Denmark is 1.9 per 100,000 persons. The corresponding incidence rates for penile, vaginal and vulvar cancer are 1.7, 0.9 and 3.6 per 100,000 males/females, respectively. The total number of new cases of these four cancers in Denmark is about 270 per year. In comparison, the total number of new cases cervical cancer is around 390 per year. The total cost of anogenital cancer to the hospital sector was estimated to be 7.6 million Euros per year. Costs associated with anal and vulvar cancer constituted the majority of the costs. Conclusions Anogenital cancer incurs considerable costs to the Danish hospital sector. It is expected that the current

    Industrially produced chemicals have been a major environmental concern across our entire Globe since the onset of rapid industrial development around the early 1900. Many of the substances being used are known to be endocrine disrupting chemicals (EDCs) and are also known to be long-range dispersed and to biomagnify to very high concentrations in the tissues of Arctic apex predators such as polar bears (Ursus maritimus). A major concern relating to EDCs is their effects on vital organ-tissues such as bone and it is possible that EDCs represent a more serious challenge to the species' survival than the more conventionally proposed prey reductions linked to climate change. We therefore analyzed penile bone mineral density (BMD) as a key phenotype for reproductive success in 279 polar bear samples born 1990-2000 representing eight polar bear subpopulations. Since EDC concentrations were not available from the same specimens, we compared BMD with published literature information on EDC concentrations. Latitudinal and longitudinal BMD and EDC gradients were clearly observed, with Western Hudson bears having the highest BMD and lowest EDCs, and North East Greenland polar bears carrying the lowest BMD and highest EDCs. A BMD vs. polychlorinated biphenyls (PCB) regression analysis showed that BMD decreased as a function of the eight subpopulations' PCB concentrations and this relationship was close to being significant (p=0.10, R(2)=0.39). Risk quotient (RQ) estimation demonstrated that PCBs could be in a range that may lead to disruption of normal reproduction and development. It is therefore likely that EDCs directly affect development and bone density in polar bears. Canadian bears had in general the best health and the North East Greenland subpopulation being at the highest risk of having negative health effects. While reductions in BMD is in general unhealthy, reductions in penile BMD could lead to increased risk of species extinction because of mating and subsequent

    The microflora of the penile skin-lined neovagina in male-to-female transsexuals is a recently created microbial niche which thus far has been characterized only to a very limited extent. Yet the knowledge of this microflora can be considered as essential to the follow-up of transsexual women. The primary objective of this study was to map the neo-vaginal microflora in a group of 50 transsexual women for whom a neovagina was constructed by means of the inverted penile skin flap technique. Secondary objectives were to describe possible correlations of this microflora with multiple patients' characteristics, such as sexual orientation, the incidence of vaginal irritation and malodorous vaginal discharge. Based on Gram stain the majority of smears revealed a mixed microflora that had some similarity with bacterial vaginosis (BV) microflora and that contained various amounts of cocci, polymorphous Gram-negative and Gram-positive rods, often with fusiform and comma-shaped rods, and sometimes even with spirochetes. Candida cells were not seen in any of the smears. On average 8.6 species were cultured per woman. The species most often found were: Staphylococcus epidermidis, Streptococcus anginosus group spp., Enterococcus faecalis, Corynebacterium sp., Mobiluncus curtisii and Bacteroides ureolyticus. Lactobacilli were found in only one of 30 women. There was no correlation between dilatation habits, having coitus, rinsing habits and malodorous vaginal discharge on the one hand and the presence of a particular species on the other. There was however a highly significant correlation between the presence of E. faecalis on the one hand and sexual orientation and coitus on the other (p = 0.003 and p = 0.027 respectively). Respectively 82%, 58% and 30% of the samples showed an amplicon after amplification with M. curtisii, Atopobium vaginae and Gardnerella vaginalis primer sets.

    Prosthesis-assisted penile reconstruction has been performed extensively to restore a cosmetically acceptable phallus. However, a large number of patients will undergo revision surgery for various prosthesis-related complications. To develop a 1-stage prosthesis-free dynamic cavernosa reconstruction method using bilateral innervated gracilis muscles and to investigate the feasibility and reliability of the surgical design. 10 fresh cadavers were dissected to assess the availability of bilateral gracilis muscles for functional cavernosa rebuilding. 11 mongrel female dogs were involved in the penile reconstruction surgery. The neophallus consisted of bilateral gracilis muscles as the neo-cavernosa, a right gracilis skin flap as the neourethra, and a lower abdominal flap with an anterior rectus sheath as the skin envelope and neo-tunica albuginea. The function and structure of the neo-phalli were assessed 7 months postoperatively. The neurovascular pedicle length of the gracilis muscles and the volume of the gracilis venter musculi were measured in the cadaveric investigation. The average dimensions of the canine neo-phalli at rest and during electrostimulated erection were obtained and the muscular fatigue-resistant curve was drawn. Histologic evaluations also were performed. The neurovascular pedicle length and volume of the gracilis muscles were sufficient to yield a nearly normal appearance of the neo-cavernosa in the cadaveric and animal studies. The muscular fatigue-resistant curve demonstrated adequate length, stiffness, and duration of erection of the neo-phalli to accomplish normal coitus. Histologic evaluations showed an intact neourethra and nearly normal muscle structure in the inner layer of the canine neo-cavernosa, except for significantly increased amount of collagen fibers and type I/III collagen ratio in the outer layer of the neo-cavernosa. The percentage of type II (fatigue-prone) muscle fibers did not change significantly. Our preclinical

    Bilateral radiographic irregularities and deformities of the proximal femoral epiphyses are features of both multiple epiphyseal dysplasia and bilateral idiopathic avascular necrosis. In the past these entities have been difficult to differentiate. This report documents radiographically the occurrence of avascular necrosis in 10 patients with multiple epiphyseal dysplasia by recognizing the superimposition of sclerosis and subchondral fissuring on pre-existing symmetrically irregular proximal femoral ossification centers. Scintigraphic (photopenia) or magnetic resonance (loss of signal) criteria of avascular necrosis confirm its added presence and help to establish an imaging scheme to identify avascular necrosis superimposed on multiple epiphyseal dysplasia.

    2000-01-01

    Chemically induced avascular necrosis of bone is a well documented entity. Indomethacin is one of the causes of this condition but is often difficult to recognise. Review of the literature shows that only one case of indomethacin induced avascular necrosis has been reported in the English language between 1966 and the present.
The case of a young healthy man, who developed avascular necrosis of head of femur after prolonged administration of indomethacin, is reported here.

    1993-01-01

    Magnetic resonance (MR) images and conventional radiographs were compared in 142 hips with avascular necrosis, and a staging system for the disease based on MR imaging was developed. MR images were classified into three patterns: a band of low signal intensity (class I); an area of low signal intensity with internal spot(s) of high signal (class II); and an area of low signal intensity without internal spots of high signal (class III). Most MR class I lesions were in radiographic stage I (normal) or II (sclerotic or cystic changes without collapse). Most MR class II lesions were in radiographic stage III (segmental collapse), and most MR class III lesions were in stage III or IV (secondary degenerative changes). The MR image classification was closely correlated with radiographic staging (p<0.01, using χ square test). We considered that this classification closely reflected the different stages of the disease according to the histopathology of the bone marrow. (author)

    -range dispersed and to biomagnify to very high concentrations in the tissues of Arctic apex predators such as polar bears (Ursus maritimus). A major concern relating to EDCs is their effects on vital organ-tissues such as bone and it is possible that EDCs represent a more serious challenge to the species......' survival than the more conventionally proposed prey reductions linked to climate change. We therefore analyzed penile bone mineral density (BMD) as a key phenotype for reproductive success in 279 polar bear samples born 1990-2000 representing eight polar bear subpopulations. Since EDC concentrations were...... not available from the same specimens, we compared BMD with published literature information on EDC concentrations. Latitudinal and longitudinal BMD and EDC gradients were clearly observed, with Western Hudson bears having the highest BMD and lowest EDCs, and North East Greenland polar bears carrying the lowest...

  5. Kaposi’s sarcoma: An unusual penile lesion in a HIV negative patient

    2017-06-01

    Full Text Available Kaposi's sarcoma (KS of the penis is a very rare lesion and it is usually observed in HIV-infected patients. We introduce a case of KS of the penis in a 75 years old HIV negative patient with a peripheral T-cell lymphoma. He came to our attention with a painful ulcerated red lesion on the glans that stretched from the urethral meatus to the coronal skin. This lesion was found to be a KS balanopreputial in the classical variant. Penile KS must be included in the differential diagnosis of genital diseases especially when the clinical features of the lesion are aspecific and diagnosis can be made histologically by performing a biopsy.

    2010-01-01

    Full Text Available Amputation of the penis is a rare condition reported from various parts of the world as isolated cases or small series of patients; the common etiology is self-mutilating sharp amputation or an avulsion or crush injury in an industrial accident. A complete reconstruction of all penile structures should be attempted in one stage which provides the best chance for full rehabilitation of the patient. We report here a single case of total amputation of the penis in an acute paranoid schizophrenic patient .The penis was successfully reattached using a microsurgical technique. After surgery, near-normal appearance and function including a good urine flow and absence of urethral stricture, capabilities of erection and near normal sensitivity were observed.

  7. Early history of inflatable penile prosthesis surgery: a view from someone who was there

    2015-04-01

    Full Text Available The publication of the use of an inflatable penile prosthesis (IPP in 1973 by Dr. FB Scott. changed the world of treatment options for erectile dysfunction (ED. Much has been written since then about techniques, improvements, management of difficult cases, complications and their management, and mechanical and device changes over time. Few reports, if any, are available in the medical literature regarding the early development, surgical techniques, and controversies surrounding its introduction to the world's urological community. This article is, for the most part, the observations of one who was "there" in the early and mid-1970's and was a witness to the history of this remarkable marvel of creativity, engineering, design, and to the personalities involved.

    Brenot-Rossi, I.

    2008-01-01

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid 99m Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

  10. Impact of penile rehabilitation with low-dose vardenafil on recovery of erectile function in Japanese men following nerve-sparing radical prostatectomy

    Yuzo Nakano

    2014-12-01

    Full Text Available Erectile dysfunction (ED is a major complication after radical prostatectomy (RP; however, debate continues regarding the efficacy of penile rehabilitation in the recovery of the postoperative erectile function (EF. This study included a total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing RP, and analyzed the postoperative EF, focusing on the significance of penile rehabilitation. In this series, 24 and 79 patients underwent bilateral and unilateral nerve-sparing RPs, respectively, and 10 or 20 mg of vardenafil was administered to 35 patients at least once weekly, who agreed to undergo penile rehabilitation. Twelve months after RP, 48 (46.6% of the 103 patients were judged to have recovered EF sufficient for sexual intercourse without any assistance. The proportion of patients who recovered EF in those undergoing penile rehabilitation (60.0% was significantly greater than that in those without penile rehabilitation (38.2%. Of several parameters examined, the preoperative International Index of Erectile Function-5 (IIEF-5 score and nerve-sparing procedure were significantly associated with the postoperative EF recovery rates in patients with and without management by penile rehabilitation, respectively. Furthermore, univariate analysis identified the preoperative IIEF-5 score, nerve-sparing procedure and penile rehabilitation as significant predictors of EF recovery, among which the preoperative IIEF-5 score and nerve-sparing procedure appeared to be independently associated with EF recovery. Considering these findings, despite the lack of independent significance, penile rehabilitation with low-dose vardenafil could exert a beneficial effect on EF recovery in Japanese men following nerve-sparing RP.

    A new method is described for evaluating arteriogenic impotence by means of noninvasive quantification of penile Doppler arterial waveforms using computerised analysis based on the Laplace Transform model. The haemodynamic changes occurring during a papaverine-induced erection in healthy potent volunteers have been recorded by this technique, which has also been shown to be capable of discriminating between a normal and an abnormal penile arterial supply in an initial study of potent and impotent men.

    Comelis, Manuela T; Bueno, Larissa M; Góes, Rejane M; Taboga, S R; Morielle-Versute, Eliana

    2018-04-01

    The penis is the reproductive organ that ensures efficient copulation and success of internal fertilization in all species of mammals, with special challenges for bats, where copulation can occur during flight. Comparative anatomical analyses of different species of bats can contribute to a better understanding of morphological diversity of this organ, concerning organization and function. In this study, we describe the external morphology and histomorphology of the penis and baculum in eleven species of molossid bats. The present study showed that penile organization in these species displayed the basic vascular mammalian pattern and had a similar pattern concerning the presence of the tissues constituting the penis, exhibiting three types of erectile tissue (the corpus cavernosum, accessory cavernous tissue, and corpus spongiosum) around the urethra. However, certain features varied among the species, demonstrating that most species are distinguishable by glans and baculum morphology and glans histological organization. Major variations in glans morphology were genus-specific, and the greatest similarities were shared by Eumops species and N. laticaudatus. The greatest interspecific similarities occurred between M. molossus and M. rufus and between Eumops species. Save for M. molossus and M. rufus, morphology of the baculum was species-specific; and in E. perotis, it did not occur in all specimens, indicating that it is probably under selection. In the histological organization, the most evident differences were number of septa and localization of the corpora cavernosa. In species with a baculum (Molossus, Eumops and Nyctinomops species), the corpora cavernosa predominantly occupied the dorsal region of the penile glans and is associated with the proximal (basal) portion of the baculum. In species that do not have a baculum (Cynomops, Molossops and Neoplatymops species), the corpora cavernosa predominantly occupied the ventro-lateral region of the glans

  13. Penile alterations at early stage of type 1 diabetes in rats

    Mingfang Tao

    Full Text Available ABSTRACT Objective Diabetes affects the erectile function significantly. However, the penile alterations in the early stage of diabetes in experimental animal models have not been well studied. We examined the changes of the penis and its main erectile components in diabetic rats. Materials and methods Male Sprague-Dawley rats were divided into 2 groups: streptozotocin (STZ-induced diabetics and age-matched controls. Three or nine weeks after diabetes induction, the penis was removed for immunohistochemical staining of smooth muscle and neuronal nitric oxide synthase (nNOS in midshaft penile tissues. The cross-sectional areas of the whole midshaft penis and the corpora cavernosa were quantified. The smooth muscle in the corpora cavernosa and nNOS in the dorsal nerves were quantified. Results The weight, but not the length, of the penis was lower in diabetics. The cross-sectional areas of the total midshaft penis and the corpora cavernosa were lower in diabetic rats compared with controls 9 weeks, but not 3 weeks after diabetes induction. The cross-sectional area of smooth muscle in the corpora cavernosa as percentage of the overall area of the corpora cavernosa was lower in diabetic rats than in controls 9 weeks, but not 3 weeks after diabetes induction. Percentage change of nNOS in dorsal nerves was similar at 3 weeks, and has a decreased trend at 9 weeks in diabetic rats compared with controls. Conclusions Diabetes causes temporal alterations in the penis, and the significant changes in STZ rat model begin 3-9 weeks after induction. Further studies on the reversibility of the observed changes are warranted.

    Bhat, Amilal; Gandhi, Ajay; Saxena, Gajendra; Choudhary, Gautam Ram

    2010-10-01

    Objective of this study was to assess the feasibility and results of preputial reconstruction and tubularized incised plate urethroplasty (TIP) in patients of proximal hypospadias with ventral penile curvature. Twenty-seven patients of proximal hypospadias who underwent preputioplasty with TIP were evaluated retrospectively. Ventral curvature was corrected by mobilization of the urethral plate with the corpus spongiosum and the proximal urethra; dorsal plication was added according to the severity of curvature. Feasibility of preputial reconstruction was assessed by applying 3 stay sutures-the first to fix the skin at the corona, the second at the junction of the inner and outer preputial skin for pulling up the skin over the glans, and the third stay on penile skin at the level of the corona for retracting the skin. Preputial reconstruction consisted of a standard 3 layered re-approximation of the margins of the dorsal hood. Age of the patients varied from 10 months to 21 years with an average of 6 years and 4 months. Ventral curvature (mild 10, moderate 13, and severe 4 cases) was corrected by the mobilization of the urethral plate and spongiosum in 14 patients, 11 cases had mobilization of the proximal urethra in addition and 2 patients required single stitch dorsal plication with the above-mentioned steps. Two patients developed urethral fistula and 1 had preputial dehiscence. Preputioplasty with TIP is feasible in proximal hypospadias with curvature without increasing the complication rate. Postoperative phimosis can be prevented by on-table testing of the adequacy of preputial skin by 3 stay sutures.

  15. A new technique, combined plication-incision (CPI, for correction of penile curvature

    Hamed Abdalla Hamed

    Full Text Available ABSTRACT Introduction Penile curvature (PC can be surgically corrected by either corporoplasty or plication techniques. These techniques can be complicated by post-operative: penile shortening, recurrent PC, painful/palpable suture knots and erectile dysfunction. Objective To avoid the complications of corporoplasty and plication techniques using a new technique: combined plication-incision (CPI. Materials and Methods Two groups (1&2 were operated upon: group 1 using CPI and group 2 using the 16-dot technique. In CPI, dots were first marked as in 16 dot technique. In each group of 4 dots the superficial layer of tunica albuginea was transversely incised (3-6mm at the first and last dots. Ethibond 2/0, passed through the interior edge of the first incision plicating the intermediate 2 dots and passed out of the interior edge of the last incision, was tightened and ligated. Vicryle 4/0, passed through the exterior edges of the incisions, was tightened and ligated to cover the ethibond knot. Results Twelve (57.1 % participants in group 2 complained of a bothering palpable knot compared to none in group 1 with statistically significant difference (P=0.005. Postoperative shortening (5mm of erect penis, encountered in 9 participants, was doubled in group 2 but with insignificant difference (P>0.05. Post-operative recurrence of PC, was encountered in only 1 (4.8% participant in group 2, compared to none in group 1, with insignificant difference (P>0.05. Post-operative erectile rigidity was normally maintained in all participants. Conclusion The new technique was superior to the 16-dot technique for correction of PC.

    Although different techniques for augmentation phalloplasty have been reported in the medical literature, this issue is still highly controversial, and none of the proposed procedures has been unanimously approved. The aim of this study is to describe an innovative surgical technique for penile girth augmentation with porcine dermal acellular grafts, through a small transverse incision at the penile base, along the penopubic junction. Between 2000 and 2009, 104 patients were referred to our institution for penile enhancement. After a preoperative psychosexual consultation and a general medical assessment, 69 patients were deemed suitable good candidates for surgery. The average penis circumference was measured at the mid-length of the penis and was 8.1 cm (5.4-10.7 cm) and 10.8 cm (6.5-15.8 cm) during flaccidity and erection, respectively. All patients received penile augmentation with porcine dermal acellular grafts. Results evaluation of an innovative technique for penile girth augmentation through exogenous porcine grafts and small penobubic incision. Postoperative measurements were performed at 6 and 12 months. At the 1-year follow-up, the average penis circumference was 11.3 cm (8.2-13.2 cm, 3.1 cm mean increase) during flaccidity and 13.2 cm (8.8-14.5 cm, 2.4 cm mean increase) during erection. No major complications occurred in the series. Minor complications were resolved with conservative treatment within 3 weeks. Sexual activity was resumed from 1 to 2 months after surgery. The psychosexual impact of the operation was beneficial in the majority of cases. Penile girth enlargement with acellular dermal matrix grafts has several advantages over augmentation with autogenous dermis-fat grafts: the elimination of donor site morbidity and a significantly shorter operation time. With this approach, through a short dorsal incision at the base of the penis, the scar is concealed in a crease covered by pubic hair and thus hardly visible. © 2012

  17. Alteration in the etiology of penile fracture in the Middle East and Central Asia regions in the last decade; a literature review

    2015-01-01

    Full Text Available Penile fracture is a well-recognized, relatively uncommon medical condition and its etiology differs according to geographic area. In this review article, we evaluated literature reported in the past decade, aiming to verify whether there has been any change in the etiology of this condition. A literature review was done for studies published in the past 10 years and focusing on the etiology of penile fracture. Inclusion criteria comprised articles in English language, of sample size more than 10 patients and originating from the Middle East and Central Asia. Data relating to the studied population, etiology of penile fracture, clinical presentation, investigations, management, and outcome was analyzed. One thousand six hundred and twenty-nine patients from 21 original articles were included in the study. The mean age ΁ standard deviation of the patients was 33.3 ΁ 3.23 years. Etiologies of penile fracture were vigorous sexual intercourse, manual bending of erect penis, vigorous masturbation, rolling over in bed and blunt trauma in 41%, 29%, 10%, 14% and 6% patients, respectively. Treatment choices were surgery and conservative, in 1580 (95%, 83 (5% patients, respectively. A higher incidence of complications was found in conservatively treated patients. As a conclusion, in the last 10 years, vigorous sexual intercourse was the commonest etiology of penile fracture in the Middle East and Central Asia regions. Surgery remains the preferred treatment option for patients diagnosed with penile fracture.

    2015-01-01

    Tissue necrosis is a rare yet potentially serious complication of intra-articular (IA) hyaluronic acid (HA) injections for treatment of knee osteoarthritis. To report a case of a patient with cutaneous necrosis after IA HA injection for treatment of knee osteoarthritis, presenting as a livedoid violaceous patch on the right knee. We report a case of cutaneous necrosis as a rare complication of IA HA injection for treatment of knee osteoarthritis. A literature review was undertaken of similar cases. Use of HA IA injections in the treatment of osteoarthritis can result in similar skin necrosis at uncommon anatomic locations corresponding to the site of HA injection. Although tissue necrosis is a rare complication, physicians need to be aware of this possibility as a complication of HA IA injections in the treatment of osteoarthritis and should be mindful of potential treatment options to manage this adverse event. © 2014 Canadian Dermatology Association.

  20. NecroQuant: quantitative assessment of radiological necrosis

    Hwang, Darryl H.; Mohamed, Passant; Varghese, Bino A.; Cen, Steven Y.; Duddalwar, Vinay

    2017-11-01

    Clinicians can now objectively quantify tumor necrosis by Hounsfield units and enhancement characteristics from multiphase contrast enhanced CT imaging. NecroQuant has been designed to work as part of a radiomics pipelines. The software is a departure from the conventional qualitative assessment of tumor necrosis, as it provides the user (radiologists and researchers) a simple interface to precisely and interactively define and measure necrosis in contrast-enhanced CT images. Although, the software is tested here on renal masses, it can be re-configured to assess tumor necrosis across variety of tumors from different body sites, providing a generalized, open, portable, and extensible quantitative analysis platform that is widely applicable across cancer types to quantify tumor necrosis.

  1. Atraumatic Pantalar Avascular Necrosis in a Patient With Alcohol Dependence.

    Callachand, Fayaz; Milligan, David; Wilson, Alistair

    2016-01-01

    In the United States, an estimated 10,000 to 20,000 new cases of avascular necrosis are diagnosed each year. We present an unusual case of atraumatic avascular necrosis with widespread hindfoot and midfoot involvement. A 62-year-old female with a history of alcohol dependence and smoking, who had previously been treated for avascular necrosis of the knee, presented with right-sided foot pain and difficulty weightbearing. Imaging studies revealed extensive avascular necrosis of the hindfoot and midfoot, which precluded simple surgical intervention. The patient was followed up for 18 months. In the last 8 months of the 18-month period, the patient managed her symptoms using an ankle-foot orthosis. A diagnosis of avascular necrosis should be considered in patients with atraumatic foot and ankle pain, especially in the presence of risk factors such as alcohol excess and smoking.

    Rates of mastectomy with immediate reconstruction are rising. Skin flap necrosis after this procedure is a recognized complication that can have an impact on cosmetic outcomes and patient satisfaction, and in worst cases can potentially delay adjuvant therapies. Many retrospective studies of this complication have identified variable event rates and inconsistent associated factors. A prospective study was designed to capture the rate of skin flap necrosis as well as pre-, intra-, and postoperative variables, with follow-up assessment to 8 weeks postoperatively. Uni- and multivariate analyses were performed for factors associated with skin flap necrosis. Of 606 consecutive procedures, 85 (14 %) had some level of skin flap necrosis: 46 mild (8 %), 6 moderate (1 %), 31 severe (5 %), and 2 uncategorized (0.3 %). Univariate analysis for any necrosis showed smoking, history of breast augmentation, nipple-sparing mastectomy, and time from incision to specimen removal to be significant. In multivariate models, nipple-sparing, time from incision to specimen removal, sharp dissection, and previous breast reduction were significant for any necrosis. Univariate analysis of only moderate or severe necrosis showed body mass index, diabetes, nipple-sparing mastectomy, specimen size, and expander size to be significant. Multivariate analysis showed nipple-sparing mastectomy and specimen size to be significant. Nipple-sparing mastectomy was associated with higher rates of necrosis at every level of severity. Rates of skin flap necrosis are likely higher than reported in retrospective series. Modifiable technical variables have limited the impact on rates of necrosis. Patients with multiple risk factors should be counseled about the risks, especially if they are contemplating nipple-sparing mastectomy.

  3. Application of hyperbaric oxygen therapy in the rehabilitation of patients after surgical correction of the penile urethral strictures

    Kotenko К.V.

    2013-12-01

    Full Text Available The aim of the article is to examine the impact and justify the use of hyperbaric oxygenation in the complex rehabilitation of patients after surgery for penile urethral strictures. Material and Methods. A group of 37 patients were examined who underwent various reconstructive operations on the urethra, 16 of which in the postoperative period in addition to conventional therapy conducted hyperbaric oxygenation. Results. It is shown that the use of hyperbaric oxygenation in the early postoperative period in patients undergoing replacement plastic of urethra can reduce the incidence of postoperative complications, and reduced the time of urethral drainage. Conclusion. An integrated approach with the use of hyperbaric oxygen therapy in the rehabilitation of patients undergoing extended replacement plastic of penile urethral strictures, reduces the amount of potential effect-dependent postoperative complications, which generally leads to shorter hospital stay after surgical treatment.

    Tabatabaei, Shahin; Harisinghani, Mukesh; McDougal, W Scott

    2005-09-01

    We evaluated lymphotropic nanoparticle enhanced magnetic resonance imaging (LNMRI) with ferumoxtran-10 in determining the presence of regional lymph node metastases in patients with penile cancer. Seven patients with squamous cell carcinoma of the penis underwent LNMRI. All patients subsequently underwent groin dissection and the nodal images were correlated with histology. We found that LNMRI had sensitivity, specificity, and positive and negative predictive values of 100%, 97%, 81.2% and 100%, respectively, in predicting the presence of regional lymph node metastases in patients with penile cancer. Lymph node scanning using LNMRI accurately predicts the pathological status of regional lymph nodes in patients with cancer of the penis. LNMRI may accurately triage patients for regional lymphadenectomy.

    2016-05-01

    Full Text Available Purpose: To investigate whether relaxation of the rat penile corpus cavernosum could be controlled with NOBL-1, a novel, lightcontrollable nitric oxide (NO releaser. Materials and Methods: Fifteen-week-old male Wistar-ST rats were used. The penile corpus cavernosum was prepared and used in an isometric tension study. After noradrenaline (10−5 M achieved precontraction, the penile corpus cavernosum was irradiated by light (470–500 nm with and without NOBL-1 (10−6 M. In addition, we noted rats’ responses to light with vardenafil (10−6 M, a phosphodiesterase-5 (PDE-5 inhibitor. Next, responses to light in the presence of a guanylate cyclase inhibitor, ODQ (1H-[1,2,4] oxadiazolo[4,3-a]quinoxalin-1-one (10−5 M, were measured. All measurements were performed in pretreated L-NAME (10−4 M conditions to inhibit endogenous NO production. Results: Corpus cavernosal smooth muscle, precontracted with noradrenaline, was unchanged by light irradiation in the absence of NOBL-1. However, in the presence of NOBL-1, corpus cavernosal smooth muscle, precontracted with noradrenaline, relaxed in response to light irradiation. After blue light irradiation ceased, tension returned. In addition, the light response was obviously enhanced in the presence of a PDE-5 inhibitor. Conclusions: This study showed that rat corpus cavernosal smooth muscle relaxation can be light-controlled using NOBL-1, a novel, light sensitive NO releaser. Though further in vivo studies are needed to investigate possible usefulness, NOBL-1 may be prove to be a useful tool for erectile dysfunction therapy, specifically in the field of penile rehabilitation.

    2015-09-01

    Full Text Available Objective: To present the management of a patient with partial disruption of both cavernosal bodies and complete urethral rupture and to propose a non-systematic review of literature about complete urethral rupture. Material and method - Case report: A 46 years old man presented to our emergency department after a blunt injury of the penis during sexual intercourse. On physical examination there was subcutaneous hematoma extending over the proximal penile shaft with a dorsal-left sided deviation of the penis and urethral bleeding. Ultrasound investigation showed an hematoma in the ventral shaft of the penis with a discontinuity of the tunica albuginea of the right cavernosal corporum. The patient underwent immediate emergency surgery consisted on evacuation of the hematoma, reparation the partial defect of both two cavernosal bodies and end to end suture of the urethra that resulted completely disrupted. Results: The urethral catheter was removed at the 12-th postoperative day without voiding symptoms after a retrograde urethrography. 6 months postoperatively the patients was evaluated with uroflowmetry demonstrating a max flow rate of 22 ml/s and optimal functional outcomes evaluated with validated questionnaires. 8 months after surgery the patients was evaluated by dynamic magnetic resonance (MRI of the penis showing only a little curvature on the left side of the penile shaft. Conclusion: Penile fracture is an extremely uncommon urologic injury with approximately 1331 reported cases in the literature till the years 2001. To best of our knowledge from 2001 up today, 1839 more cases have been reported, only in 159 of them anterior urethral rupture was associated and in only 22 cases a complete urethral rupture was described. In our opinion, in order to prevent long term complications, in case of clinical suspicion of penile fracture, especially if it is associated to urethral disruption, emergency surgery should be the first choice of treatment.

    In order to evaluate the effect of penile enhancement, we retrospectively reviewed the data of the patients operated with autologous dermal graft implantation combined with a modified penile degloving procedure. The patients with the complaints of small penis, asking for penile augmentation, and normal erectile function were psychologically screened and enrolled. Data of follow-up visit including patient demographics, medical history, surgical procedure, patient-reported outcomes were analysed. In all, 30 eligible persons were operated. After degloving of the penis, the suspensory ligament was incised and the tunica albuginea was fixed to the proximal tunica dartos at the penile base. Then, the dermis graft was implanted on the dorsal surface of the tunica albuginea. The file of follow-up visit was available in 17 (57%) patients. The mean age was 23.7 years (19-35 years) and the mean follow-up was 13 months (range, 4-24 months). During the follow-up period, the average gain in the penis length was 2.7 cm in flaccid and 0.8 cm in erection, respectively. And the average gain in the penis circumference was 1.5 cm in flaccid and 1.2 cm in erection, respectively. Also, psychosexual sexual self-esteem and confidence of the patients were significantly improved (p enhancement of the penis, however, further clinical studies with a larger patient population are necessary. © 2016 American Society of Andrology and European Academy of Andrology.

  10. Necrosis, a regulated mechanism of cell death La necrosis, un mecanismo regulado de muerte celular

    Three types of cellular death have been defined by morphological and biochemical criteria: apoptosis, necrosis and autophagy. Apoptosis is a regulated cell death, mainly mediated by caspases; autophagy induces degradation of intracellular damaged organelles through the formation of vesicles that fuse with hydrolytic vacuoles.

     

    Necrosis has been traditionally defined by the rupture the cytoplasmic membrane with subsequent release of intracellular material, triggering localized inflammatory Intrinsic cellular activities and the events preceding cellular collapse are critical to determine the type of tissue damage.

     

    The fact that all three types of cellular death can coexist in any organ and tissue with different availabilities of ATP, suggests that necrosis can be conceived as an active event and that to some extent it may be regulated. Alterations in the structure of proteins and in the

    Full Text Available Objectives. Severe penile inadequacy in adolescents is rare. Phallic reconstruction to treat this devastating condition is a major challenge to the reconstructive surgeon. Phallic reconstruction using the free radial forearm flap (RFF or the pedicled anterolateral thigh flap (ALTF has been routinely used in female-to-male transsexuals. Recently we started to use these techniques in the treatment of severe penile inadequacy. Methods. Eleven males (age 15 to 42 years were treated with a phallic reconstruction. The RFF is our method of choice; the ALTF is an alternative when a free flap is contraindicated or less desired by the patient. The RFF was used in 7 patients, the ALTF in 4 patients. Mean followup was 25 months (range: 4–49 months. Aesthetic and functional results were evaluated. Results. There were no complications related to the flap. Aesthetic results were judged as “good” in 9 patients and “moderate” in 2 patients. Sensitivity in the RFF was superior compared to the ALTF. Four patients developed urinary complications (stricture and/or fistula. Six patients underwent erectile implant surgery. In 2 patients the erectile implant had to be removed due to infection or erosion. Conclusion. In case of severe penile inadequacy due to whatever condition, a phalloplasty is the preferred treatment nowadays. The free radial forearm flap is still the method of choice. The anterolateral thigh flap can be a good alternative, especially when free flaps are contraindicated, but sensitivity is markedly inferior in these flaps.

    The neuroeffectors which relax penile smooth muscle and lead to erection are unknown; physiological studies of human corpus cavernosum, in vitro, have suggested a significant role of cholinergic neurotransmission. To further characterize the importance of cholinergic nerves, biopsies of human corpus cavernosum were obtained at the time of penile prosthesis implantation. Tissues were incubated in 3 H-choline (10 -5 M, 80 Ci/mmol) in oxygenated physiological salt solution at 37 0 C, pH 7.4 for 1 hour. Radiolabelled compounds were extracted with perchloric acid (0.4 M) and acetylcholine and choline were separated by HPLC; 14 C-acetylcholine was used as internal standard. 3 H-choline was accumulated by the tissues (20 +/- 1.9 fmol/mg), and 3 H-acetylcholine was synthesized (4.0 +/- 1.1 fmol/mg). In control experiments, heating of the tissue blocked synthesis of 3 H-acetylcholine. Inhibition of high affinity choline transport by hemicholinium-3 (10 -5 M) diminished tissue accumulation of 3 H-choline and significantly reduced the synthesis of 3 H-acetylcholine (0.5 +/ 0.2 fmol/mg, p < 0.05). These results provide direct evidence of neuronal accumulation of choline and enzymatic conversion to acetylcholine in human corpus cavernosum. Taken together with the physiological studies, it can be concluded that cholinergic neurotransmission in human corpus cavernosum plays a role in penile erection

    2012-02-01

    Self-insertion of penile foreign bodies is performed worldwide, largely due to a perception that it will enhance sexual performance and virility. There are relatively few cases reported in the United States. We report three cases of Hispanic men incarcerated in separate southwest United States prisons who utilized a similar technique to insert foreign bodies fabricated out of dominos into the subcutaneous tissues of the penis. Details of the three cases were retrospectively reviewed. Resolution of the case. In each case, an incarcerated Hispanic male or fellow inmate filed a domino into a unique shape for placement under the penile skin. Utilizing the tip of a ballpoint pen or a sharpened shard of plastic to create a puncture wound, each man inserted the domino fragment into the subcutaneous tissue of the penis. All three men presented with infection requiring operative removal. Incarcerated males put themselves at risk for injury and infection when attempting penile enhancement with improvised equipment. © 2011 International Society for Sexual Medicine.

  16. Predictive value of histologic tumor necrosis after radiation.

    Chen, Y; Taghian, A G; Rosenberg, A E; O'Connell, J; Okunieff, P; Suit, H D

    2001-12-20

    Postsurgical evaluation of histologic changes of tumors after preoperative chemotherapy and/or radiotherapy has been a routine clinical practice of pathologists and oncologists. There appears to be secure evidence that the extent of tumor necrosis vs. viable tumor cells postchemotherapy is a clinically useful predictor of outcome. The significance of histologic tumor necrosis after radiotherapy, however, has not been clearly established and deserves further investigation. We investigated the correlation between histological extent of tumor necrosis, survival of tumor transplants, and radiation doses in an experimental model using three human tumor xenografts. Three human tumor cell lines were investigated: STS-26, SCC-21, and HGL-21. Tumors were grown subcutaneously in athymic nude mice and received external beam radiation of different doses. Tumors were excised 2 weeks postirradiation. One-half of the tumor was divided into 1-mm(3) fragments and transplanted to naive mice. The other half was examined for histologic tumor necrosis. Transplant survival was strongly correlated with radiation dose, TCD(p) (radiation dose that results in local tumor control in proportion, p, to irradiated tumors). In contrast, there was no clear association between transplant survival rate and the extent of tumor necrosis. The experimental model demonstrated a strong inverse correlation between radiation doses and tumor transplant survival. Histologic tumor necrosis did not correlate well with radiation doses or transplant survival rates. Despite common practices in histologic examination of tumors posttherapy, clinical interpretations and implications of histologic tumor necrosis after radiotherapy should be considered with caution.

  17. United Kingdom nationwide study of avascular necrosis of the jaws including bisphosphonate-related necrosis.

    Rogers, S N; Palmer, N O A; Lowe, D; Randall, C

    2015-02-01

    We aimed to record all new patients who presented to departments of oral surgery, oral medicine, and oral and maxillofacial surgery, and to dental hospitals in the UK, with avascular necrosis of the jaws including bisphosphonate-related necrosis (BRONJ) over a 2-year period (1 June 2009-31 May 2011). They were eligible irrespective of age, cause, or coexisting conditions. Data on incidence, clinical characteristics, risk factors, and coexisting conditions were collected. A total of 383 cases were registered: 369 were described as BRONJ, 5 as avascular necrosis, and 9 were unknown. Bisphosphonates had been given orally in 207 (56%), intravenously in 125 (34%), both orally and intravenously in 27 (7%), and was unknown in 9 (2%); one had been given denosumab. The main risk factor was dental extraction, and the mandible was commonly affected. The median duration of administration until onset of BRONJ was 3 years in those treated intravenously and 4 years in those treated orally. Levels of engagement with the study varied between regions, and extrapolation from the 2 most involved (Merseyside and Northern Ireland) found around 8.2-12.8 cases/million/year, which is 508-793 patients/year across the UK. To our knowledge this is one of the first studies to estimate national rates of BRONJ. It confirms that the risk and incidence are low. With changes in trends for antiresorptive bone medication, and increasing numbers of elderly people, it would be useful to repeat the registration in the future.

  18. Postnatal penile growth concurrent with mini-puberty predicts later sex-typed play behavior: Evidence for neurobehavioral effects of the postnatal androgen surge in typically developing boys.

    2015-03-01

    The masculinizing effects of prenatal androgens on human neurobehavioral development are well established. Also, the early postnatal surge of androgens in male infants, or mini-puberty, has been well documented and is known to influence physiological development, including penile growth. However, neurobehavioral effects of androgen exposure during mini-puberty are largely unknown. The main aim of the current study was to evaluate possible neurobehavioral consequences of mini-puberty by relating penile growth in the early postnatal period to subsequent behavior. Using multiple linear regression, we demonstrated that penile growth between birth and three months postnatal, concurrent with mini-puberty, significantly predicted increased masculine/decreased feminine behavior assessed using the Pre-school Activities Inventory (PSAI) in 81 healthy boys at 3 to 4years of age. When we controlled for other potential influences on masculine/feminine behavior and/or penile growth, including variance in androgen exposure prenatally and body growth postnally, the predictive value of penile growth in the early postnatal period persisted. More specifically, prenatal androgen exposure, reflected in the measurement of anogenital distance (AGD), and early postnatal androgen exposure, reflected in penile growth from birth to 3months, were significant predictors of increased masculine/decreased feminine behavior, with each accounting for unique variance. Our findings suggest that independent associations of PSAI with AGD at birth and with penile growth during mini-puberty reflect prenatal and early postnatal androgen exposures respectively. Thus, we provide a novel and readily available approach for assessing effects of early androgen exposures, as well as novel evidence that early postnatal aes human neurobehavioral development.

    The incidence of radiation necrosis has increased secondary to greater use of combined modality therapy for brain tumors and stereotactic radiosurgery. Given that its characteristics on standard imaging are no different that tumor recurrence, it is difficult to diagnose without use of more sophisticated imaging and nuclear medicine scans, although the accuracy of such scans is controversial. Historically, treatment had been limited to steroids, hyperbaric oxygen, anticoagulants, and surgical resection. A recent prospective randomized study has confirmed the efficacy of bevacizumab in treating radiation necrosis. Novel therapies include using focused interstitial laser thermal therapy. This article will review the diagnosis and treatment of radiation necrosis

  20. Avascular necrosis of the femoral head presenting as trochanteric bursitis.

    Mandell, B F

    1990-01-01

    Five patients are described with avascular necrosis of the femoral head who presented with ipsilateral trochanteric bursitis, in the absence of clearcut hip joint disease. Avascular necrosis was indicated by magnetic resonance imaging. It is suggested that clinical trochanteric bursitis, especially when refractory to local corticosteroid treatment, may be the initial sign of hip disease. In the patient with risk factor(s) for avascular necrosis that diagnosis should be considered and evaluated with appropriate studies, such as magnetic resonance imaging, to prevent weight bearing at an early stage and permit possible surgical decompression in the hope of postponing or obviating the need for total hip replacement.

  1. Mandibular bone necrosis after use of paraformaldehyde-containing paste

    Chi-hwan Lee

    2016-11-01

    Full Text Available Paraformaldehyde has been used in the past as a pulpotomy agent. However, it has a severe cytotoxic effect and may cause alveolar bone necrosis. Depulpin, a devitalizing agent containing 49% paraformaldehyde, is no longer used frequently due to its severe side effects. In the two cases described in the present study, Depulpin was used as a devitalizing agent during root canal treatment. It caused a gradual loss of sensibility in adjacent teeth, gingival necrosis, and osteomyelitis. This case report demonstrates the serious side effects of using a paraformaldehyde-containing paste as a devitalizing agent for pulp, particularly mandibular bone necrosis.

    The usefulness of MRI in carpal avascular necrosis was investigated in 20 cases, 16 in lunates, 3 in scaphoids and 1 in triquetrum, with T1 and T2 weighted images of the spin echo and T2 weighted images of the field echo. Early diagnosis of carpal bone necrosis was possible when the T1 weighted image showed a moderate low intensity signal. A high intensity signal in the T2 weighted image indicated the onset of revascularization, and a favorable prognosis. A normal signal indicated healing of carpal avascular necrosis. MRI was found to be very useful in establishing the diagnosis and in determining the prognosis of carpal osteonecrosis. (author)

    A 58-year-old female developed avascular necrosis of her trapezoid approximately 3 months after undergoing carpometacarpal arthroplasty. The patient was treated conservatively with immobilization and had complete resolution of her clinical symptoms during her year of follow-up. Additionally, radiographic examination showed complete restoration of the height of her trapezoid approximately 1 year after the index procedure. Avascular necrosis of the trapezoid is extremely rare with very few cases described in the literature. This is the first description of avascular necrosis following carpometacarpal arthroplasty.

  5. Plaquing procedure for infectious hematopoietic necrosis virus

    Burke, J.A.; Mulcahy, D.

    1980-01-01

    A single overlay plaque assay was designed and evaluated for infectious hematopoietic necrosis virus. Epithelioma papillosum carpio cells were grown in normal atmosphere with tris(hydroxymethyl)aminomethane- or HEPES (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid)-buffered media. Plaques were larger and formed more quickly on 1- to 3-day-old cell monolayers than on older monolayers. Cell culture medium with a 10% addition of fetal calf serum (MEM 10) or without serum (MEM 0) were the most efficient virus diluents. Dilution with phosphate-buffered saline, saline, normal broth, or deionized water reduced plaque numbers. Variations in the pH (7.0 to 8.0) of a MEM 0 diluent did not affect plaque numbers. Increasing the volume of viral inoculum above 0.15 ml (15- by 60-mm plate) decreased plaquing efficiency. Significantly more plaques occurred under gum tragacanth and methylcellulose than under agar or agarose overlays. Varying the pH (6.8 to 7.4) of methylcellulose overlays did not significantly change plaque numbers. More plaques formed under the thicker overlays of both methylcellulose and gum tragacanth. Tris(hydroxymethyl)aminomethane and HEPES performed equally well, buffering either medium or overlay. Plaque numbers were reduced when cells were rinsed after virus adsorption or less than 1 h was allowed for adsorption. Variation in adsorption time between 60 and 180 min did not change plaque numbers. The mean plaque formation time was 7 days at 16 degrees C. The viral dose response was linear when the standardized assay was used.

    2018-01-01

    Avascular necrosis (AVN) of the talus can be a cause of significant disability and is a difficult problem to treat. The most common cause is a fracture of the talus. We have done a systematic review of the literature with the following aims: (1) identify and summarize the available evidence in literature for the treatment of talar AVN, (2) define the usefulness of radiological Hawkins sign and magnetic resonance imaging in early diagnosis, and (3) provide patient management guidelines. We searched MEDLINE and PUBMED using keywords and MESH terminology. The articles' abstracts were read by two of the authors. Forty-one studies met the inclusion criteria of the 335 abstracts screened. The interventions of interest included hindfoot fusion, conservative measures, bone grafting, vascularized bone graft, core decompression, and talar replacement. All studies were of Level IV evidence. We looked to identify the study quality, imprecise and sparse data, reporting bias, and the quality of evidence. Based on the analysis of available literature, we make certain recommendations for managing patients of AVN talus depending on identified disease factors such as early or late presentation, extent of bone involvement, bone collapse, and presence or absence of arthritis. Early talar AVN seems best treated with protected weight bearing and possibly in combination with extracorporeal shock wave therapy. If that fails, core decompression can be considered. Arthrodesis should be saved as a salvage procedure in late cases with arthritis and collapse, and a tibiotalocalcaneal fusion with bone grafting may be needed in cases of significant bone loss. Role of vascularized bone grafting is still not defined clearly and needs further investigation. Future prospective, randomized studies are necessary to guide the conservative and surgical management of talar AVN.

    2015-10-01

    Autologous fat grafts are rich in adipose-derived stem cells, providing optimal soft-tissue replacement and significant quantities of angiogenic growth factor. Although fat grafts (FG) are used in several clinical conditions, the use of FG in urethral repairs and the effects of FG to urethral repairs have not yet been reported. An experimental study was performed to evaluate the effect of FG on urethral angiogenesis and tissue growth factor (GF) levels. Sixteen Wistar albino, adult, male rats were allocated into two groups: the control group (CG) (n = 8) and the experiment group (EG) (n = 8). After anesthetization of all rats, 3-mm vertical incisions were made on the urethras, and then sutured with interrupted 5/0 vicryl sutures. The operations were performed under a stereo dissecting microscope under magnification (×20). In the CG, no additional procedure was performed. In the EG after the same surgical procedure, 1 mm(3) FG was removed from the inguinal region by sharp dissection with a knife. The grafts were trimmed to 1 × 1 mm dimensions on millimeter paper. The FGs were placed on the repaired urethras. The skin was then closed. Samples from urethral and penile skin were taken 21 days after surgery in both groups. Density and intensity of staining with vascular-endothelial GF (VEGF), VEGF-receptor, and endothelial-GF receptor (EGFR) in the endothelial and mesenchymal cells of the penile urethral vessels were immunohistochemically evaluated. Data obtained from immunohistochemical evaluations were analyzed with SPSS 15.0. The P-values lower than 0.05 were considered as significant. Density of VEGF staining was significantly decreased in the vascular endothelium of the EG compared to the CG (P factor levels, which is contrary to the literature data. Fat grafting has an immunohistochemical effect on the growth factor levels that are related to angiogenesis after urethral repair. It is difficult to make a firm conclusion about the role of fat grafting on urethral

    2012-08-01

    This study aimed to investigate the efficacy and safety of autologous fat injection (AFI) for penile girth enhancement (PGE) in patients with thin penises. This study investigated 52 patients with a small penile circumference who underwent AFI for PGE and were followed up for more than 6 months. The patients whose proximal one third (G1) and distal one third of their penis (G2) had a mean thickness of 7.4 cm or less were selected as subjects. After fat suction using a liposuction device, fat was evenly injected into the superficial, middle, and deep layers of the Colles' fascia. Patient age and operative time were analyzed. The G1, G2, flaccid (L1), stretched length (L2), and five-item version of the International Index of Erectile Function-5 (IIEF-5) before and 6 months after the surgery were compared. Postoperative complications were surveyed. The patient mean age was 42.15 years (range, 22-56) years, and the operative time was 44.44 min (range, 37-49 min). The injected fat volume was 38.54 ml (range, 25-49 ml). Preoperatively, G1 was 7.01±0.39 cm, and G2 was 7.06±0.37 cm. Postoperatively, G1 was 9.29±0.82 cm (P<0.001), and G2 was 9.34±0.86 (P<0.001) cm 6 months after the surgery. The difference between L1 and L2 before and after the surgery was not significant. The IIEF-5 was 19.10±3.22 before the surgery and 19.90±3.05 after the surgery (P=0.001). The only complication was nodular fat observed in one case (1.92%). The use of AFI for PGE in men with thin penises was effective and safe without major complications. This journal requires that authors assign a level of evidence to each article.

    Heuck, F.H.W.; Treugut, H.

    1984-01-01

    The pathogenesis of bone necrosis is discussed with special attention and with respect to metabolic, hormonal, and vascular factors. The influence of statics and dynamics of the hip joint bones for the development of aseptic necrosis are discussed. 45 patients with ''idiopathic femoral head necroses'' were observed, including 6 cases of renal osteopathy following renal transplantation and immune suppression therapy, 14 cases of long term corticoid therapy, and 11 cases of liver diseases of different genesis. The femoral head necrosis understood as complication of an osteopathy. In our patients there were 31 males and 14 females - which means higher involvement of males. Plain radiological findings and CT-findings of changes of the femoral heat structure in different stages of the disease are described. Early diagnosis of metabolic and hormonal osteopathies is demanded for a joint keeping therapy of the beginning femoral head necrosis. (orig.) [de

  15. Mammographic and sonographic features of fat necrosis of the breast

    Upadhyaya, Vidya S; Uppoor, Raghuraj; Shetty, Lathika

    2013-01-01

    Imaging features of fat necrosis vary depending on its stage of evolution and can mimic malignancy in late stages. Imaging may suffice to differentiate fat necrosis in the early stages from malignancy and thus avoid unnecessary biopsy. In this pictorial essay, we present combination of benign features in mammography and/or ultrasonography (USG) that can lead to imaging diagnosis of fat necrosis. The follow-up imaging features of fat necrosis which mirror its pathophysiological evolution have also been demonstrated. To summarize, in the appropriate clinical setting, no mammographic features suspicious for malignancy should be present. When the typical mammographic features are not present, USG can aid with the diagnosis and follow up USG can confirm it

    Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. A 38-year-old man complaining of a 4-month history of mild pain on the base of his right thumb. MRI scan was performed. The clinical presentation and the imaging findings indicated avascular osteonecrosis of the trapezium. The patient was treated with immobilization of the wrist joint for a period of six weeks. Three months later, the patient was free of symptoms and the MRI scan revealed a normal trapezium. AVN of trapezium is extremely rare. Our case shows that immobilization of an early stage avascular necrosis of the trapezium might be a treatment option.

    2016-01-01

    Microglia respond to focal cerebral ischemia by increasing their production of the neuromodulatory cytokine tumor necrosis factor, which exists both as membrane-anchored tumor necrosis factor and as cleaved soluble tumor necrosis factor forms. We previously demonstrated that tumor necrosis factor...... reduced infarct volumes at one and five days after stroke. This was associated with improved functional outcome after experimental stroke. No changes were found in the mRNA levels of tumor necrosis factor and tumor necrosis factor-related genes (TNFR1, TNFR2, TACE), pro-inflammatory cytokines (IL-1β, IL-6...... knockout mice display increased lesion volume after focal cerebral ischemia, suggesting that tumor necrosis factor is neuroprotective in experimental stroke.

  4. Simultaneous penile-vaginal intercourse orgasm is associated with satisfaction (sexual, life, partnership, and mental health).

    Brody, Stuart; Weiss, Petr

    2011-03-01

    Previous multivariate research found that satisfaction was associated positively with frequency of specifically penile-vaginal intercourse (PVI; as opposed to other sexual activities) as well as with vaginal orgasm. The contribution to satisfaction of simultaneous orgasm produced by PVI merited direct examination in a large representative sample. To examine the associations of aspects of satisfaction (sexual, life, own mental health, partner relationship) with consistency of simultaneous orgasm produced by PVI (as well as with PVI frequency and vaginal orgasm consistency). A representative sample of Czechs (N = 1,570) aged 35-65 years completed a survey on aspects of satisfaction, PVI frequency, vaginal orgasm consistency, and consistency of simultaneous orgasm produced by PVI (the latter being a specially timed version of vaginal orgasm for women). Analysis of variance of satisfaction components (LiSat scale items) from age and the sexual behaviors. For both sexes, all aspects of satisfaction were associated with simultaneous PVI orgasm consistency and with PVI frequency (except female life satisfaction). All aspects of satisfaction were also associated with vaginal orgasm consistency. Multivariate analyses indicated that PVI frequency and simultaneous orgasm consistency make independent contributions to the aspects of satisfaction for both sexes. For both sexes, PVI frequency and simultaneous orgasm produced by PVI (as well as vaginal orgasm for women) are associated with greater life, sexual, partnership, and mental health satisfaction. Greater support for these specific aspects of sexual activity is warranted. © 2010 International Society for Sexual Medicine.

    The Scrotal and Penile Imaging Working Group (SPI-WG) appointed by the board of the European Society of Urogenital Radiology (ESUR) has produced recommendations for magnetic resonance imaging (MRI) of the scrotum. The SPI-WG searched for original and review articles published before September 2016 using the Pubmed and Medline databases. Keywords used were 'magnetic resonance imaging', 'testis or testicle or testicular', 'scrotum', 'intratesticular', 'paratesticular', 'extratesticular' 'diffusion-weighted', 'dynamic MRI'. Consensus was obtained among the members of the subcommittee. The expert panel proposed recommendations using Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. The recommended MRI protocol should include T1-, T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced MRI. Scrotal MRI can be clinically applied for lesion characterisation (primary), including both intratesticular and paratesticular masses, differentiation between germ-cell and non-germ-cell neoplasms (evolving), characterisation of the histological type of testicular germ cell neoplasms (TGCNs, in selected cases), local staging of TGCNs (primary), acute scrotum (in selected cases), trauma (in selected cases) and undescended testes (primary). The ESUR SPI-WG produced this consensus paper in which the existing literature on MRI of the scrotum is reviewed. The recommendations for the optimal imaging technique and clinical indications are presented. (orig.)

  7. Penile-preserving surgery for primary urothelial carcinoma of male urethra

    Haoping Tai

    2015-06-01

    Full Text Available Primary urethral carcinoma is a rare cancer, comprising <1% of all malignancies. The location of this lesion presents a certain dilemma of treatment between efficacy and quality of life. We report an 84-year-old male patient, with a history of chronic hepatitis C, hypertension, and transient ischemic accident, who presented with dysuria and acute urinary retention. The intravenous urography showed mild prostatic enlargement, but no stone or filling defect was noted in the upper urinary tract. On urethrocystoscopy, multiple papillary tumors were found at the pendulous urethra, and the pathology of biopsy confirmed urothelial carcinoma. The patient was admitted, and electroresection with fulguration of urethral tumors was performed owing to the patient's old age and poor performance status. Intraurethral and intravesical chemotherapy with mitomycin C was regularly given at the outpatient clinic. Recurrent urothelial carcinomas were noted twice in the first 2 years of follow up, and repeated transurethral resections were done. Unfortunately, liver cirrhosis with hepatocellular carcinoma was diagnosed last June, for which he received transcatheter arterial chemoembolization. No recurrence of urethral cancer has been found on semiannual cystoscopy in the past 3 years. Penile-preserving surgery is a reasonable surgical option for elderly primary urethral carcinoma patients with acceptable oncological outcome and good quality of life.

  8. High-dose-rate interstitial brachytherapy for the treatment of penile carcinoma

    Background: interstitial low-dose-rate (LDR) brachytherapy allows conservative treatment of T1-T2 penile carcinoma. High-dose-rate (HDR) is often considered to be dangerous for interstitial implants because of a higher risk of complications, but numerous reports suggest that results may be comparable to LDR. Nevertheless, there are no data in the literature available regarding HDR interstitial brachytherapy for carcinoma of the penis. Case report: a 64-year-old man with T1 NO MO epidermoid carcinoma of the glans is reported. Interstitial HDR brachytherapy was performed using the stainless hollow needle technique and a breast template for fixation and good geometry. The dose delivered was 18 x 3 Gy twice daily. Results: after 232 days from brachytherapy, the patient was without any evidence of the tumor, experienced no serious radiation-induced complications, and had a fully functional organ. Conclusion: HDR interstitial brachytherapy is feasible in selected case of penis carcinoma, when careful planning and small single fractions are used. (orig.)

  9. Glandectomy with preservation of corpora cavernosa in the treatment of penile carcinoma

    Fonseca Aluizio G. da

    2003-01-01

    Full Text Available INTRODUCTION: The objective of this work is to describe a conservative surgical technique as an alternative to classic penile amputations, aiming the local control of the disease, in addition to trying to preserve the patient's sexual function. SURGICAL TECHNIQUE: After a circular incision of the skin around the penis, the subfascial plane is developed until the base of the organ. The dorsal neurovascular bundle and the urethra are isolated in their distal extremities. The neurovascular bundle is sectioned distally. A retrocoronal dissection plane is developed between the glans and the corpora cavernosa. When this stage is complete, the glans is fixed only to the urethra, which is distally sectioned as well. The neurovascular bundle is fixed to the dorsal albuginea. Following the spatulation of the urethra, a neomeatus is created using the overlay skin of the penis. Between January 2001 and July 2002, we employed this technique in 6 patients who had epidermoid carcinoma of the penis, which were limited to the glans, superficial, well or moderately differentiated and measuring up to 3 cm. COMMENTS: Several conservative surgical methods for treatment of carcinoma of the penis aim the organ's preservation, in an attempt of improving the quality of life of patients, however the indexes of local recurrence and failure in disease control are significant. The described technique showed to be safe and effective for disease control, in addition to preserving sexual function in all patients who were treated, representing, thus, a quite appealing conservative surgical alternative in selected cases.

  10. Study of the response of the penile corporal tissue and cavernosus muscles to micturition

    2008-03-01

    Full Text Available Abstract Background The reaction of the corpora cavernosa (CC, the corpus spongiosum (CS, the bulbocavernosus (BCM and ischiocavernosus (ICM muscles to passage of urine through the urethra during micturition is not known. We investigated the hypothesis that the passage of urine through the urethra stimulates the corporal tissue and cavernosus muscles. Methods In 30 healthy men (mean age 42.8 ± 11.7 years, the electromyographic activity (EMG of the CC, CS, BCM, and ICM were recorded before and during micturition, and on interruption of and straining during micturition. These tests were repeated after individual anesthetization of urethra, corporal tissue, and cavernosus muscles. Results During micturition, the slow wave variables (frequency, amplitude, conduction velocity of the CC and CS decreased while the motor unit action potentials of the BCM and ICM increased; these EMG changes were mild and returned to the basal values on interruption or termination of micturition. Micturition after individual anesthetization of urethra, corporal tissue and cavernosal muscles did not effect significant EMG changes in these structures, while saline administration produced changes similar to those occurring before saline administration. Conclusion The decrease of sinusoidal and increase of cavernosus muscles' EMG activity during micturition apparently denotes sinusoidal relaxation and cavernosus muscles contraction. Sinusoidal muscle relaxation and cavernosus muscles contraction upon micturition are suggested to be mediated through a 'urethro-corporocavernosal reflex'. These sinusoidal and cavernosus muscle changes appear to produce a mild degree of penile tumescence and stretch which might assist in urinary flow during micturition.

    2013-02-01

    To evaluate expansion of image-guided interventional cryoablation techniques usually employed for pain management to address the feasibility, safety, and efficacy of treatment for a urologic condition with otherwise limited treatment options, premature ejaculation (PE). Prospective institutional review board approval was obtained, and 24 subjects with PE were enrolled. All patients underwent unilateral percutaneous computed tomography-guided cryoablation of the dorsal penile nerve (DPN). Postprocedural intravaginal ejaculatory latency times (IELTs) and PE Profile (PEP) results served as outcome variables. In addition, subjects were asked whether they would have the procedure done again based on their experience at the 180- and 360-day marks. The technical success rate was 100%. Baseline average IELT was 54.7 seconds ± 7.8 (n = 24), which increased to a maximum of 256 seconds ± 104 (n = 11; P = .241) by day 7 and decreased to 182.5 seconds ± 87.8 (n = 6; P = .0342) by day 90. The mean IELT remained at 182.5 seconds ± 27.6 at day 180 (n = 23; PIELTs significantly improved at 180 and 360 days, and 83% of subjects reported that they would undergo the procedure again if given the same opportunity. There were no procedure-related complications. CT-guided percutaneous unilateral cryoablation of the DPN is a feasible, safe, single-day outpatient procedure for the treatment of symptomatic PE.

  12. [Hypervascularization syndrome of the penis following arterialization of the dorsal penile vein for erectile impotence].

    Fritsch, P; Grubauer, G; Hilty, N; Biedermann, H

    1989-07-01

    A hypervascularization syndrome following arterialization of the deep dorsal vein of the penis to amend venous erectile impotence is a rare cause of penile ulcers that has not previously been described in the dermatological literature. Arterialization is performed by installing a shunt from the inferior epigastric artery or a venous bypass from the femoral artery to the deep dorsal vein of the penis, resulting in a blockage of venous outflow and in retrograde inflow into the corpora cavernosa. Complications arise as a result of persistently elevated blood pressure in the deep venous system and the erectile tissue in 10-20% of cases and are most often linked to dilatation of the shunt: the consequences are enlargement and induration of the glans, hazard of phimosis and paraphimosis, pulsation of the penis, micturation difficulties and, ultimately, ulceration of the glans. Surgical reduction of the arterial inflow ("banding" of the shunt) is the only therapeutic procedure that reduces hypervascularization without compromising the newly gained erectile function.

  13. Implication of snail in metabolic stress-induced necrosis.

    Cho Hee Kim

    2011-03-01

    Full Text Available Necrosis, a type of cell death accompanied by the rupture of the plasma membrane, promotes tumor progression and aggressiveness by releasing the pro-inflammatory and angiogenic cytokine high mobility group box 1. It is commonly found in the core region of solid tumors due to hypoxia and glucose depletion (GD resulting from insufficient vascularization. Thus, metabolic stress-induced necrosis has important clinical implications for tumor development; however, its regulatory mechanisms have been poorly investigated.Here, we show that the transcription factor Snail, a key regulator of epithelial-mesenchymal transition, is induced in a reactive oxygen species (ROS-dependent manner in both two-dimensional culture of cancer cells, including A549, HepG2, and MDA-MB-231, in response to GD and the inner regions of a multicellular tumor spheroid system, an in vitro model of solid tumors and of human tumors. Snail short hairpin (sh RNA inhibited metabolic stress-induced necrosis in two-dimensional cell culture and in multicellular tumor spheroid system. Snail shRNA-mediated necrosis inhibition appeared to be linked to its ability to suppress metabolic stress-induced mitochondrial ROS production, loss of mitochondrial membrane potential, and mitochondrial permeability transition, which are the primary events that trigger necrosis.Taken together, our findings demonstrate that Snail is implicated in metabolic stress-induced necrosis, providing a new function for Snail in tumor progression.

  15. Use of negative-pressure dressings and split-thickness skin grafts following penile shaft reduction and reduction scrotoplasty in the management of penoscrotal elephantiasis.

    Stokes, Tracey H; Follmar, Keith E; Silverstein, Ari D; Weizer, Alon Z; Donatucci, Craig F; Anderson, Everett E; Erdmann, Detlev

    2006-06-01

    From 1988 to 2005, 8 men who presented with penoscrotal elephantiasis underwent penile shaft degloving and reduction scrotoplasty, followed by transplantation of a split-thickness skin graft (STSG) to the penile shaft. The etiology of elephantiasis in these patients included self-injection of viscous fluid and postsurgical obstructive lymphedema. In the 6 most recent cases, negative-pressure dressings were applied over the STSG to promote graft take, and STSG take rate was 100%. The results of our series corroborate those of a previous report, which showed circumferential negative-pressure dressings to be safe and efficacious in bolstering STSGs to the penile shaft. Furthermore, these results suggest that the use of negative-pressure dressings may improve graft take in this patient population.

    Purpose: To report feasibility, benefit and complications of penile angiography and superselective penile embolization in arterial priapism. Materials and Methods: Four consecutive patients (aged 28, 29, 40 and 49 years), who underwent penile angiography for arterial priapism (high-flow priapism) within a four-year period, were identified by a keyword search of our radiology information system. One patient had sustained a direct penile trauma (severe blow to the erected penis) and three patients suffered from recurrent spontaneous priapism. All patients had previously undergone corporeal aspiration and noradrenaline injection to achieve detumescence. Two patients had one or several unsuccessful spongiocavernous shunt procedures. Results: In three of the four patients, superselective pudendal and penile angiography demonstrated pathologic arteriocavernous shunting. In two of the three patients, superselective embolization using a coaxial micro-catheter was attempted. In one of the two patients, the cavernous artery became spastic before embolization material was actually injected, inducing immediate and lasting detumescence. In the other patient, unilateral Gelfoam embolization led to immediate detumescence but the priapism recurred 12 hours after the procedure. A subsequent contralateral Gelfoam embolization was successful. Erectile function was preserved in all cases. No procedure-related complications occurred. Conclusion: Our experience supports the prevailing opinion found in the current literature that superselective coaxial embolization constitutes the treatment of choice in patients with high-flow priapism. Prognosis is good with high probability of preserving the erectile function. (orig.)

    There is a growing body of evidence to support the direct link between obstructive bladder dysfunction and erectile dysfunction (ED). However, there have been few pathophysiological studies to determine the relationship between lower urinary tract syndrome (LUTS) and ED. As the transforming growth factor-β1 (TGF-β1) that induces the synthesis of collagen in the penile tissues is critical for the development of ED, the first aim of this study was to investigate the expression of TGF-β1 in the penis from male rabbits with chronic partial bladder outlet obstruction (PBOO). Besides, it has been suggested that oxidative stress plays a significant role in the pathophysiological mechanism of ED. Thus, the second aim of this study was to further investigate whether the urinary or serum oxidative stress markers are involved in chronic PBOO-induced penile dysfunction. A total of 16 male New Zealand White rabbits were separated equally into four groups: a control group and PBOO groups obstructed for 2, 4 and 8 weeks respectively. Using the RT-PCR and Western blot analysis, a progressive increase of TGF-β1 in penis was found at 2, 4 and 8 weeks after obstruction. Moreover, the biomarkers for oxidative stress or oxidative damage were significantly detected in the penis of rabbits after PBOO, which include the enhancement of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in urine and plasma, plasma malondialdehyde (MDA) and total antioxidant capacity (TAC), as well as reduction of glutathione (GSH). On the basis of our results, the increase of TGF-β1 and elevated systemic oxidative stress may play key roles to contribute to penile dysfunction after chronic PBOO. © 2011 The Authors.

    Since 14 years of age, the patient had experienced extreme penile pain within seconds of initial sexual arousal through masturbation. Penile pain was so severe that he rarely proceeded to orgasm or ejaculation. After 7 years of undergoing multiple unsuccessful treatments, he was concerned for his long-term mental health and for his future ability to have relationships. To describe a novel collaboration among specialists in sexual medicine, neurophysiology, and spine surgery that led to successful management. Collaborating health care providers conferred with the referring physician, patient, and parents and included a review of all medical records. Elimination of postpubertal intense penile pain during sexual arousal. The patient presented to our sexual medicine facility at 21 years of age. The sexual medicine physician identifying the sexual health complaint noted a pelvic magnetic resonance imaging report of an incidental sacral Tarlov cyst. A subsequent sacral magnetic resonance image showed four sacral Tarlov cysts, with the largest measuring 18 mm. Neuro-genital testing result were abnormal. The neurophysiologist hypothesized the patient's pain at erection was produced by Tarlov cyst-induced neuropathic irritation of sensory fibers that course within the pelvic nerve. The spine surgeon directed a diagnostic injection of bupivacaine to the sacral nerve roots and subsequently morphine to the conus medullaris of the spinal cord. The bupivacaine produced general penile numbness; the morphine selectively decreased penile pain symptoms during sexual arousal without blocking penile skin sensation. The collaboration among specialties led to the conclusion that the Tarlov cysts were pathophysiologically mediating the penile pain symptoms during arousal. Long-term follow-up after surgical repair showed complete symptom elimination at 18 months after treatment. This case provides evidence that (i) Tarlov cysts can cause sacral spinal nerve root radiculitis through

    To re-evaluate the role of diabetes mellitus (DM) as a risk factor for penile implant infection by exploring the association between glycated haemoglobin (HbA1c) levels and penile implant infection rates and to define a threshold value that predicts implant infection. We conducted a multicentre prospective study including all patients undergoing penile implant surgery between 2009 and 2015. Preoperative, perioperative and postoperative management were identical for the entire cohort. Univariate analysis was performed to define predictors of implant infection. The HbA1c levels were analysed as continuous variables and sequential analysis was conducted using 0.5% increments to define a threshold level predicting implant infection. Multivariable analysis was performed with the following factors entered in the model: DM, HbA1C level, patient age, implant type, number of vascular risk factors (VRFs), presence of Peyronie's disease (PD), body mass index (BMI), and surgeon volume. A receiver operating characteristic (ROC) curve was generated to define the optimal HbA1C threshold for infection prediction. In all, 902 implant procedures were performed over the study period. The mean patient age was 56.6 years. The mean HbA1c level was 8.0%, with 81% of men having a HbA1c level of >6%. In all, 685 (76%) implants were malleable and 217 (24%) were inflatable devices; 302 (33.5%) patients also had a diagnosis of PD. The overall infection rate was 8.9% (80/902). Patients who had implant infection had significantly higher mean HbA1c levels, 9.5% vs 7.8% (P HbA1c level, we found infection rates were: 1.3% with HbA1c level of 9.5% (P HbA1c level, whilst a high-volume surgeon had a protective effect and was associated with a reduced infection risk. Using ROC analysis, we determined that a HbA1c threshold level of 8.5% predicted infection with a sensitivity of 80% and a specificity of 65%. Uncontrolled DM is associated with increased risk of infection after penile implant surgery

  20. Penile lengthening procedure with V-Y advancement flap and an interposing silicone sheath: A novel methodology

    2012-01-01

    Full Text Available Surgery to augment penile length has become increasingly common. Lack of standardization of this controversial procedure has led to a wide variety of poorly documented surgical techniques, with unconvincing results. The most commonly used technique involves release of the suspensory ligament, with an advancement of an infrapubic skin flap onto the penis via a V-Y plasty. This technique has a major drawback of the possibility of reattachment of the penis to the pubis. We describe a new technique of interposing a silicone sheath along with V-Y advancement flap that overrides this drawback and minimizes the loss of the gained length.

    Full Text Available To gain insight into female-to-male HIV sexual transmission and how male circumcision protects against this mode of transmission, we visualized HIV-1 interactions with foreskin and penile tissues in ex vivo tissue culture and in vivo rhesus macaque models utilizing epifluorescent microscopy. 12 foreskin and 14 cadaveric penile specimens were cultured with R5-tropic photoactivatable (PA-GFP HIV-1 for 4 or 24 hours. Tissue cryosections were immunofluorescently imaged for epithelial and immune cell markers. Images were analyzed for total virions, proportion of penetrators, depth of virion penetration, as well as immune cell counts and depths in the tissue. We visualized individual PA virions breaching penile epithelial surfaces in the explant and macaque model. Using kernel density estimated probabilities of localizing a virion or immune cell at certain tissue depths revealed that interactions between virions and cells were more likely to occur in the inner foreskin or glans penis (from local or cadaveric donors, respectively. Using statistical models to account for repeated measures and zero-inflated datasets, we found no difference in total virions visualized at 4 hours between inner and outer foreskins from local donors. At 24 hours, there were more virions in inner as compared to outer foreskin (0.0495 +/- 0.0154 and 0.0171 +/- 0.0038 virions/image, p = 0.001. In the cadaveric specimens, we observed more virions in inner foreskin (0.0507 +/- 0.0079 virions/image than glans tissue (0.0167 +/- 0.0033 virions/image, p<0.001, but a greater proportion was seen penetrating uncircumcised glans tissue (0.0458 +/- 0.0188 vs. 0.0151 +/- 0.0100 virions/image, p = 0.099 and to significantly greater mean depths (29.162 +/- 3.908 vs. 12.466 +/- 2.985 μm. Our in vivo macaque model confirmed that virions can breach penile squamous epithelia in a living model. In summary, these results suggest that the inner foreskin and glans epithelia may be important sites

    Ninety-five patients with primary or metastatic brain tumors were treated with the intraoperative radiotherapy (IORT). In seven cases, surgery was performed a second time because of suspected of tumor recurrence, later found to be a radiation necrosis. Tumorous lesions were irradiated by IORT in the range of 15 Gy to 20 Gy together with external radiotherapy in the 30 Gy to 72 Gy range. In follow-up postcontrast CT studies, irregularly-shaped lesions appeared at the IORT site and increased in size with the perifocal low density area on subsequent scans. The images resembled those seen in tumor recurrence. Histopathologic changes seen during the follow-up surgery were thought to be mainly the result of radiation necrosis, though viable tumor cells at the marginal tumor site were one possible etiology. A coagulation necrosis with a fibrin exudate was observed in the IORT portal area and the vascular walls exhibited marked degeneration which is symptomatic of delayed radiation necrosis. Thus, post-IORT radiation necrosis is thought to be a direct reaction to this technique, and the delayed absorption of necrotic tissue to be a direct reaction to this technique, and the delayed absorption of necrotic tissue clearly indicates the possibility of adverse effects in its use for treatment of brain tumors.

    2007-01-01

    Purpose: Because blocking vascular endothelial growth factor (VEGF) from reaching leaky capillaries is a logical strategy for the treatment of radiation necrosis, we reasoned that bevacizumab might be an effective treatment of radiation necrosis. Patients and Methods: Fifteen patients with malignant brain tumors were treated with bevacizumab or bevacizumab combination for their tumor on either a 5 mg/kg/2-week or 7.5 mg/kg/3-week schedule. Radiation necrosis was diagnosed in 8 of these patients on the basis of magnetic resonance imaging (MRI) and biopsy. MRI studies were obtained before treatment and at 6-week to 8-week intervals. Results: Of the 8 patients with radiation necrosis, posttreatment MRI performed an average of 8.1 weeks after the start of bevacizumab therapy showed a reduction in all 8 patients in both the MRI fluid-attenuated inversion-recovery (FLAIR) abnormalities and T1-weighted post-Gd-contrast abnormalities. The average area change in the T1-weighted post-Gd-contrast abnormalities was 48% (±22 SD), and the average change in the FLAIR images was 60% (±18 SD). The average reduction in daily dexamethasone requirements was 8.6 mg (±3.6). Conclusion: Bevacizumab, alone and in combination with other agents, can reduce radiation necrosis by decreasing capillary leakage and the associated brain edema. Our findings will need to be confirmed in a randomized trial to determine the optimal duration of treatment

    A central tenet of tuberculosis pathogenesis is that caseous necrosis leads to extracellular matrix destruction and bacterial transmission. We reconsider the underlying mechanism of tuberculosis pathology and demonstrate that collagen destruction may be a critical initial event, causing caseous necrosis as opposed to resulting from it. In human tuberculosis granulomas, regions of extracellular matrix destruction map to areas of caseous necrosis. In mice, transgenic expression of human matrix metalloproteinase 1 causes caseous necrosis, the pathological hallmark of human tuberculosis. Collagen destruction is the principal pathological difference between humanised mice and wild-type mice with tuberculosis, whereas the release of proinflammatory cytokines does not differ, demonstrating that collagen breakdown may lead to cell death and caseation. To investigate this hypothesis, we developed a 3-dimensional cell culture model of tuberculosis granuloma formation, using bioelectrospray technology. Collagen improved survival of Mycobacterium tuberculosis-infected cells analyzed on the basis of a lactate dehydrogenase release assay, propidium iodide staining, and measurement of the total number of viable cells. Taken together, these findings suggest that collagen destruction is an initial event in tuberculosis immunopathology, leading to caseous necrosis and compromising the immune response, revealing a previously unappreciated role for the extracellular matrix in regulating the host-pathogen interaction. © The Author 2015.

    2018-01-01

    Full Text Available Introduction. Uterine artery embolization (UAE is a minimally invasive intervention that is used in the treatment of fibroids. UAE can lead to complications including postembolization syndrome, postprocedure pain, infection, endometrial atrophy leading to secondary amenorrhea, and uterine necrosis. Uterine necrosis after UAE is very rare and hence poses a clinical dilemma for any clinician in its identification and management. We document a case of uterine necrosis after UAE and conduct a literature review on its causation, clinical features, and management principles. Case. A patient presented one month after UAE with abdominal pain and abdominal vaginal discharge. Her work-up revealed features of possible uterine necrosis with sepsis and she was scheduled for a laparotomy and a subtotal hysterectomy was performed. She was subsequently managed with broad spectrum antibiotic and recovered well. Conclusion. Uterine necrosis after UAE is a rare occurrence and we hope the documentation of this case will add to the body of knowledge around it. Theories that explain its occurrence include the use of small particles at embolization, the use of Contour-SE a spherical poly-vinyl alcohol, and lack of collateral supply to the uterus. Its symptoms may be nonspecific but unremitting abdominal pain is invariably present. Finally although conservative management may be successful at times, surgical management with hysterectomy will be required in some cases. The prognosis is good after diagnosis and surgical management.

  6. Management of infected pancreatic necrosis: state of the art

    Roberto Rasslan

    Full Text Available ABSTRACT Pancreatic necrosis occurs in 15% of acute pancreatitis. The presence of infection is the most important factor in the evolution of pancreatitis. The diagnosis of infection is still challenging. Mortality in infected necrosis is 20%; in the presence of organic dysfunction, mortality reaches 60%. In the last three decades, there has been a real revolution in the treatment of infected pancreatic necrosis. However, the challenges persist and there are many unsolved questions: antibiotic treatment alone, tomography-guided percutaneous drainage, endoscopic drainage, video-assisted extraperitoneal debridement, extraperitoneal access, open necrosectomy? A step up approach has been proposed, beginning with less invasive procedures and reserving the operative intervention for patients in which the previous procedure did not solve the problem definitively. Indication and timing of the intervention should be determined by the clinical course. Ideally, the intervention should be done only after the fourth week of evolution, when it is observed a better delimitation of necrosis. Treatment should be individualized. There is no procedure that should be the first and best option for all patients. The objective of this work is to critically review the current state of the art of the treatment of infected pancreatic necrosis.

    Total amputation, as a treatment for advanced penile cancer, significantly debilitates the patient's quality of life and sexual function. The aim of the study was to assess the quality of life in patients who had undergone total penectomy. The questionnaires EORTC QLQ C-30, SES, CMNI, and a modified IIEF-15 questionnaire, were sent to 11 patients. A total of 10 patients returned the questionnaires completed. The results of the overall quality of life, the median result in individual domains, as assessed by the EORT QLQ C-30 questionnaire, were clearly lower than the reference results. There were statistically significant differences in the results of the QLQ C-30, concerning the role-functioning domain in relation to age (p = 0.008) and education (p = 0.032), in the domain of emotional functioning in relation to education (p = 0.008) and in the domains of physical functioning in relation to the partner relationship (p = 0.032). A significant number of patients were sexually inactive. Sexual activity as defined by touching the area of the pubic symphysis at the scars of the penis, touching and fondling perianal areas or the scrotum and watching things/people that cause excitement was observed in 2/10, 1/10 and 2/10 of patients respectively. In 5/6 of these patients, partnership relationships did not deteriorate, including one patient for whom the relationship actually improved. The results obtained indicate that total amputation of the penis significantly affects one's sex life and overall quality of life. However, this does not have negative implications in terms of partnership relations, self-assessment or the evaluation of masculinity.

    Penile cancer (PeCa) is a rare, aggressive malignancy often associated with the human papillomavirus (HPV). The practice of a personalized risk-adapted approach is not yet established. This study is to assess the relationship between HPV tumor status and chemoradiotherapy (CRT) in PeCa locoregional control (LRC). We retrospectively identified patients with HPV status who were diagnosed with squamous cell carcinoma of the penis and treated with surgical resection between 1999 and 2016. The relationship between tumor/treatment characteristics and LRC were analyzed with univariate and multivariate Cox proportional hazard regression analysis (UVA and MVA, respectively). Time-to-event outcomes were estimated with Kaplan-Meier curves and compared via log-rank tests. Fifty-one patients were identified. The median follow-up was 36.6 months. Patients were primarily HPV-negative (HPV-) (n = 28, 55%), and pathologic node positive (pN+) (55%). The 2 year LRC rate was 54%. pN+ patients had a significantly lower 2 year LRC (37 vs. 81%, p = 0.002). In the subgroup analysis of pN+ patients (n = 28), there was a LRC benefit associated with the addition of CRT (HR 0.19; 95% CI 0.05-0.70, p = 0.012) and HPV-positive (HPV+) disease (HR 0.18; 95% CI 0.039-0.80, p = 0.024) using MVA. HPV+ patients treated with CRT had improved 2 year LRC compared to HPV- patients (83 vs. 38%, p = 0.038). Adjuvant CRT and HPV+ disease independently predicted for improved LRC in pN+ PeCa. In HPV+ PeCa, the LRC benefit was primarily observed in patients treated with adjuvant CRT. Prospective investigation of HPV+ and CRT is required to further delineate their roles in optimizing PeCa treatment.

  9. Analysis of DNA evidence recovered from epithelial cells in penile swabs.

    2003-06-01

    In the rape case presented here, no semen, hair, or other biological evidence were left by the perpetuator at the crime scene or on the victim. The alleged assailant was arrested soon after the crime. A classical stain recovery technique using cotton swab moistened with sterile water was taken for recovering potential female epithelial cells and leukocytes deposited on the alleged assailant's penis during sexual assault. The organic method used for DNA extraction was quantified according to the slot-blot procedure and amplified at 9 and 15 polymorphic loci. Penile swab revealed a DNA profile of mixed origin. In addition to the suspect's DNA profile, DNA contribution from the victim was identified as a minor component in the mixture. Frequency of the profile resulted in a value of 5 x 10(-14) for the multiplex systems AmpFlSTR Plus and 2.5 x 10(-18) for the multiplex system PowerPlex 16, taking into account only non-overlapping alleles between the suspect and the victim from the minor component in the DNA mixture. Moreover, three additional alleles were observed at D21S11 locus by use of PowerPlex and STR SGM plus primers, which could not belong to the suspect. The victim's DNA profile showed the same three-banded genotype at this locus. The same pattern was detected when the victim's saliva or blood were used as reference samples. Our laboratory finding was consistent with the police report that the victim was a person with Down syndrome, a human genetic disease mainly resulting from trisomy (triplication) of the 21 chromosome.

    We retrospectively evaluated the clinical outcome of penile prosthesis implantation (PPI) in Chinese patients with severe erectile dysfunction (SED). From July 2000 to December 2011, 224 patients (mean age: 35.9±11.8 years, range: 20–75 years) with SED underwent PPI by experienced surgeon according to standard PPI procedure at our centre. A malleable prosthesis (AMS 650) was implanted in 45 cases (20.1%), and a three-piece inflatable prosthesis (AMS 700 CXM or AMS 700 CXR) was implanted in 179 cases (79.9%). Surgical outcomes, including postoperative complications, clinical efficacy and couple satisfaction, were evaluated over than 6 months postoperatively using medical record abstraction, IIEF-5, quality of life (QoL) scores, and the patient/partner sexual satisfaction score proposed by Bhojwani et al. Of the 224 patients eligible for the study, 201 subjects (89.7%) completed follow-up. All of patients could perform sexual intercourse post PPI with the mean postoperative IIEF-5 and QoL scores were 20.02±2.32 and 5.28±0.76, respectively, which were significantly improved compared with the preoperative scores (6.29±1.5 and 2.13±0.84, Preported by 178 men (88.6%), and overall satisfaction with the PPI surgery was reported by 89.0% of men and 82.5% of partners. Patient satisfaction in the three-piece inflatable prosthesis group was higher than in the malleable prosthesis group (P<0.05). Satisfaction, however, between the types of prostheses, did not differ in the partner survey. PPI is a safe and effective treatment option for Chinese patients with SED and experienced surgeon perform PPI according to standard PPI procedure could reduce the postoperative complications of PPI and could improve patient satisfaction ratio and QoL.

    Currently, most centres use 2-D planar lymphoscintigraphy when performing dynamic sentinel lymph node biopsy in penile cancer patients with clinically impalpable inguinal nodes. This study aimed to investigate the role of SPECT/CT following 2-D planar lymphoscintigraphy (dynamic and static) in the detection and localization of sentinel lymph nodes in the groin. A qualitative (visual) review was performed on planar followed by SPECT/CT lymphoscintigraphy in 115 consecutive patients (age 28-86 years) who underwent injection of {sup 99m}Tc-nanocolloid followed by immediate acquisition of dynamic (20 min) and early static scans (5 min) initially and further delayed static (5 min) images at 120 min followed by SPECT/CT imaging. The lymph nodes detected in each groin on planar lymphoscintigraphy and SPECT/CT were compared. A total of 440 and 467 nodes were identified on planar scintigraphy and SPECT/CT, respectively. Overall, SPECT/CT confirmed the findings of planar imaging in 28/115 cases (24%). In the remaining 87 cases (76%), gross discrepancies were observed between planar and SPECT/CT images. SPECT/CT identified 17 instances of skin contamination (16 patients, 13%) and 36 instances of in-transit lymphatic tract activity (24 patients, 20%) that had been interpreted as tracer-avid lymph nodes on planar imaging. In addition, SPECT/CT identified 53 tracer-avid nodes in 48 patients (42%) that were not visualized on planar imaging and led to reclassification of the drainage basins (pelvic/inguinal) of 27 tracer-avid nodes. The addition of SPECT/CT improved the rate of detection of true tracer-avid lymph nodes and delineated their precise (3-D) anatomic localization in drainage basins. (orig.)

  12. Chordee and Penile Shortening Rather Than Voiding Function Are Associated With Patient Dissatisfaction After Urethroplasty.

    2017-05-01

    To identify factors that predict patient satisfaction after urethroplasty by prospectively examining patient-reported quality of life scores using 3 validated instruments. A 3-part prospective survey consisting of the International Prostate Symptom Score (IPSS), the International Index of Erectile Function (IIEF) score, and a urethroplasty quality of life survey was completed by patients who underwent urethroplasty preoperatively and at 6 months postoperatively. The quality of life score included questions on genitourinary pain, urinary tract infection (UTI), postvoid dribbling, chordee, shortening, overall satisfaction, and overall health. Data were analyzed using descriptive statistics, paired t test, univariate and multivariate logistic regression analyses, and Wilcoxon signed-rank analysis. Patients were enrolled in the study from February 2011 to December 2014, and a total of 94 patients who underwent a total of 102 urethroplasties completed the study. Patients reported statistically significant improvements in IPSS (P Wilcoxon signed-rank analysis revealed significant improvements in pain scores (P = .02), UTI (P 4 cm and the absence of UTI, pain, shortening, and chordee as predictors of patient satisfaction. Multivariate analysis of quality of life domain scores identified absence of shortening and absence of chordee as independent predictors of patient satisfaction following urethroplasty (P < .01). Patient voiding function and quality of life improve significantly following urethroplasty, but improvement in voiding function is not associated with patient satisfaction. Chordee status and perceived penile shortening impact patient satisfaction, and should be included in patient-reported outcome measures. Copyright © 2017 Elsevier Inc. All rights reserved.

    We investigated safety and efficacy outcome pertaining to the Mentor Alpha-1, 3-piece inflatable penile prosthesis for impotence treatment. A 2-phase, multi-institutional, large scale retrospective study, with independently analyzed medical record (phase I) and questionnaire (phase II) data from consecutive eligible patients of 7 physician investigators was performed from March to October 1993. In phase I there were no morbidities of any type in 394 of the 434 patients (90.8%) (mean age 61 years, range 24 to 88) who underwent Alpha-1 implantation (mean followup 22.2 months, range 0.67 to 44.5). The risk of prosthesis malfunction (fluid leak and auto-inflation) was 2.5%. No cylinder aneurysms were reported. A total of 93.1% of Alpha-1 devices was free from explantation (4.4%) or revision surgery (2.5%) for approximately 2 years from the original implant date. Kaplan-Meier actuarial analyses revealed that cumulative survival of the Alpha-1 prostheses at 12, 24 and 36 months was 98 +/- 1%, 93 +/- 2% and 85 +/- 7% until device malfunction, and 91 +/- 2% 83 +/- 4% and 75 +/- 7% until surgical intervention (revision or explantation). In phase II 89% of the men claimed fulfilled expectations with the Alpha-1 prosthesis as impotence treatment. Satisfaction responses 80% or greater were noted with regard to intercourse ability and confidence, and device rigidity and function. Implantation did not result in greater than 80% satisfaction in partner relationships or feelings (as judged by the patient), social or work confidence, or intercourse frequency. Factors adversely affecting satisfaction included partner feelings of dissatisfaction (as judged by the patient), specific physician investigators and need for explantation/revision surgery. In 1 of the largest multi-institutional implant outcome studies thus far performed, safety and efficacy data concerning the Alpha-1 contemporary inflatable device were found markedly improved over earlier inflatable prostheses and now

    Tribulus terrestris has been used as an aphrodisiac. However, little is known about the effects and mechanism of action of T. terrestris on penile erection. Therefore, the effect of a T. terrestris extract and the mechanism of action of the extract on relaxation of the corpus cavernosum (CC) were investigated. The erectogenic effects of an oral preparation of the extract were also assessed. The relaxation effects and mechanism of action of the T. terrestris extract on rabbit CC were investigated in an organ bath. The intracavernous pressure (ICP) was calculated after oral administration of the extract for 1 month to evaluate whether the relaxation response of the CC shown in the organ bath occurred in vivo. Additionally, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) were measured in the CC by immunoassay. Smooth muscle relaxation was expressed as the percentage decrease in precontraction induced by phenylephrine. The ICP was also assessed in rats after oral administration of the extract for 1 month, and changes in concentrations of cGMP and cAMP were monitored. Concentration-dependent relaxation effects of the extract on the CC were detected in the organ bath study. Relaxation of the CC by the T. terrestris extract was inhibited in both an endothelium-removed group and an L-arginen methyl ester pretreatment group. The ICP measured after oral administration of the T. terrestris extract for 1 month was higher than that measured in the control group, and a significant increase in cAMP was observed in the T. terrestris extract group. The T. terrestris extract induced concentration-dependent relaxation of the CC in an organ bath. The mechanism included a reaction involving the nitric oxide/nitric oxide synthase pathway and endothelium of the CC. Moreover, in an in vivo study, the T. terrestris extract showed a significant concentration-dependent increase in ICP. Accordingly, the T. terrestris extract may improve erectile function.

    Objective: The objective of this study was to evaluate the effectiveness of 3-factor prothrombin complex concentrate (3F-PCC) compared to 4-factor PCC (4F-PCC) in warfarin-associated bleeding. Methods: This multicenter, retrospective, cohort study analyzed data from patients admitted between May 2011 and October 2014 who received PCC for warfarin-associated bleeding. The primary outcome was the rate of international normalized ratio (INR) normalization, defined as an INR ≤1.3, after administration of 3F-PCC compared to 4F-PCC. Other variables of interest included the incidence of additional reversal agents, new thromboembolic events, and mortality. Results: A total of 134 patients were included in the analysis. The average dose of PCC administered was 24.6 ± 9.3 units/kg versus 36.3 ± 12.8 units/kg in the 3F-PCC and 4F-PCC groups, respectively, P < 0.001. Baseline INR in the 3F-PCC and 4F-PCC groups was 3.61 ± 2.3 and 6.87 ± 2.3, respectively P < 0.001. 4F-PCC had a higher rate of INR normalization at first INR check post-PCC administration compared to 3F-PCC (84.2% vs. 51.9%, P = 0.0001). Thromboembolic events, intensive care unit and hospital length of stay, and mortality were similar among both groups. Conclusion: The use of 4F-PCC leads to a more significant reduction in INR compared to 3F-PCC though no difference in mortality or length of stay was observed. Thromboembolism rates were similar among both groups. PMID:29619338

    Primary dissection of a peripheral artery without involvement of the aorta is a rare entity. Warfarin is currently used as the standard oral anticoagulant in a variety of clinical settings. We report here on a case of focal dissection of the common iliac artery and the superficial femoral artery following prophylactic treatment with warfarin for a prosthetic heart valve. The patient's laboratory results showed a high international normalized ratio and prolongation of the activated partial thromboplastin time. Angiography showed a dissection of the left common iliac artery and the right superficial femoral artery. His symptoms immediately disappeared after deploying stents to the arterial dissections

    Pediatric digital necrosis resulting in revision amputation is a devastating outcome following digital dressing application. We report a series of 4 pediatric patients (age: 21 months-11 years) who presented for surgical consultation related to digital ischemia and irreversible necrosis following the application of Coban digital dressings. A review of the literature demonstrated that such injuries had not previously been described. In our case series, Coban dressing was utilized as a deterrent for thumb sucking, fingertip tuft fractures with nail bed lacerations, and a phalanx fracture secondary to crush injury. All 4 children suffered digital necrosis secondary to Coban dressings and ultimately required revision amputation. We discuss risks factors, application practices, and strategies to minimize complications with digital dressings in the pediatric population with the intent of creating awareness among hand surgeons to help promote safe practices and improve patient outcomes.

    Full Text Available Idiopathic isolated cecal necrosis is a clinical problem characterized by right-sided inferior abdominal pain. It is rarely seen, develops due to decreased blood flow to the colon and, imitates acute appendicitis. Its clinical signs are similar to many illnesses causing sensitivity in the right inferior quadrant and, the diagnosis is generally determined during surgery. An 86-year-old male patient presented with the complaints of abdominal pain, trichiniasis, nausea and vomiting. Surgical intervention was decided when physical examination and laboratory results were taken into consideration. After diagnostic laparoscopy, right hemicolectomy was performed because of cecal necrosis. While the mortality and morbidity rates for ischemic bowel disease are high, prognosis for early diagnosed patients with isolated cecal necrosis is better, provided that timely surgical treatment is decided.

    Ten patients with avascular femoral head necrosis and four normal adults were examined by magnetic resonance imaging (MRI). In addition, the relationship between MRI and pathophysiology of three operated-on avascular femoral heads was evaluated. The medullary cavities of the normal femoral heads had a strong signal intensity on the saturation recovery (SR) image due to fat marrow, and the T/sub 1/ relaxation time was 160 +- 11 msec. In avascular femoral head necrosis, the necrotic area had a low signal intensity on the SR image and a prolonged T/sub 1/ relaxation time, while the reactive fibrous area had more prolonged T/sub 1/ relaxation time. For these reasons, MRI was found to show the pathological changes of avascular femoral head necrosis and can be expected to be useful for making early diagnoses and operation planning.
