Paraphimosis
Daniel Yachia in Text Atlas of Penile Surgery, 2007
In adults the cause of paraphimosis is mostly iatrogenic. It can occur as the result of urethral manipulations such as insertion of a Foley catheter or cystoscopy. Before such manipulations the preputium is retracted, to prepare the glans. All medical personnel should be aware of this risk, and remember to pull the preputium back to its normal position. If the prepuce is not returned to its normal position after manipulation and its opening is narrow, it may become trapped below the corona. This circumferential ring acts as a tourniquet, disturbing blood and lymphatic flow to and from the prepuce and the glans. The constriction sometimes can be so tight that, if left untreated, it can result in distal penile gangrene (Figure 4.2).
Clinical Cases
Magnus Garrioch, Bosseau Murray in Anaesthesia, 2015
Ninety percent of patients with scleroderma experience Raynaud’s phenomenon. It is also a component of the CREST (calcinosis, Raynaud’s phenomenon, oesophageal dysmotility, sclerodactyly, telangectasia) syndrome. These patients have small vessel occlusive disease that may lead to digital pitting or ulceration. Later obliterative endarteritis may occur and result in thrombosis, ischaemic changes in the skin of the digits and nails, superficial necrosis and finally gangrene. Sudden onset renal failure or necrosis of the bowel may result from endarteritis. Rheumatology specialists should be consulted prior to a surgical procedure in a patient suspected of CREST syndrome.
Gangrene, Hospital
Glenna R Schroeder-Lein in The Encyclopedia of Civil War Medicine, 2008
Hospital gangrene was a severe streptococcal wound infection that proved fatal to many soldiers, both North and South, during the Civil War. Because it was much more serious than other types of gangrene and developed only in large hospitals in major cities where many kinds of infections were treated, researchers suggest that it may have resulted from a combination of several types of bacteria.
Fournier Gangrene: First Manifestation of Occult Rectal Cancer
Published in Acta Chirurgica Belgica, 2011
J. Ruiz-Tovar, L. Córdoba, J.M. Devesa
Fournier gangrene is a necrotizing fasciitis of the genital and perineal region. Diverse factors predispose to Fournier gangrene, such as diabetes mellitus, ethylism, liver dysfunction, haematological disorders, obesity or recent regional instrumentation. Rectal tumours can also predispose to Fournier gangrene; most of the reported cases are perforated or unresectable colorectal tumours, but some cases of anorectal cancer diagnosed after recovery from Fournier gangrene have also been reported. In these cases, the presence of a rectal tumour at the time of, or prior to, diagnosis of Fournier gangrene could not be ruled out. We present three cases of rectal cancer whose first manifestation was as Fournier gangrene.
A case of idiopathic scrotal gangrene (Fournier) with perineal extension
Published in Annals of Tropical Medicine & Parasitology, 1983
A case of idiopathic or Fournier's gangrene of the scrotum is described with unusual extension to the perineum. The clinical features of this disease are summarized. The literature is reviewed for extra genital extension of this gangrene of unknown aetiology. Coincidental association between infections with Onchocerca volvulus and scrotal gangrene was observed.
A Fournier’s gangrene after transurethral resection of the prostate
Published in Acta Chirurgica Belgica, 2011
C. Kara, O.F. Bozkurt, A. Unsal
Fournier’s gangrene is a rapidly progressive and potentially lethal disease that affects the perineum and male genitalia. Predisposing factors included age, diabetes, alcoholism, malnutrition, and low socio-economic status. Herein, we present a 70-year-old patient who developed Fournier’s gangrene following transurethral resection of the prostate. He had no predispositional factors to develop Fournier’s gangrene.
