1/626. Treatment of cutaneous ulcers with benzoyl peroxide.benzoyl peroxide, a powerful organic oxidizing agent, was applied topically according to a carefully developed technique to cutaneous ulcers of different types. The healing time was shortened greatly by the rapid development of healthy granulation tissue and the quick ingrowth of epithelium. Exceptionally large pressure ulcers with deep cavities, undercut edges and sinus tracts were sucessfully treated, as were stasis ulcers of long duration resistant to all other therapy. There were only 13 treatment failures among the 133 cases. The slow, sustained release of oxygen by benzoyl peroxide was though to be responsible for the success. The only complications were contact irritant dermatitis in 3% and contact allergic dermatitis in 2% of patients treated.- - - - - - - - - - ranking = 1keywords = ulcer (Clic here for more details about this article) |
2/626. Myofasciocutaneous expansion in the tegumentary rehabilitation of the amputation stump.In post-traumatic amputations, in particular in leg amputations, the presence of an unstable scar or of ulcerous areas that are difficult to heal in the site of the amputation stump constitutes a repair problem that is not easily solved. In this specific field of reconstruction skin expansion has earned significant agreement, and is even considered to be a safe and reliable method for the surgical rehabilitation of the amputation stump, allowing us to obtain high-quality tegumentary covering, with no excessive thickness, that adapts well to the prosthesis and to the underlying skeleton, and that is characterized by good sensitivity of protection. Tegumentary amplification may, in some cases, also become myocutaneous, allowing us to obtain more tissue thickness for protection in patients submitted to chronic loading that lasts longer and in those with thin teguments, in which traditional expansion could determine excessive narrowing of the tegumentary covering, following atrophy caused by compression of the subcutaneous adipose tissue.- - - - - - - - - - ranking = 0.14285714285714keywords = ulcer (Clic here for more details about this article) |
3/626. Increased dermal angiogenesis after low-intensity laser therapy for a chronic radiation ulcer determined by a video measuring system.Acute and chronic radiation-induced dermatitis can occur after high doses of ionizing radiation of the skin. We describe a patient with a long-lasting radiotherapy-induced ulcer that healed after low-intensity laser therapy. A video measuring system was used to determine the number of dermal vessels in the ulcer before and after laser treatment. We found a statistically significant increase in the number of dermal vessels after low-intensity laser therapy in both the central and marginal parts of the ulcer compared with its pretreatment status.- - - - - - - - - - ranking = 1keywords = ulcer (Clic here for more details about this article) |
4/626. Oxalate kinetics and reversal of the complications after orthotopic liver transplantation in a patient with primary hyperoxalosis type 1 awaiting renal transplantation.We present the case of a young woman with end-stage renal disease secondary to primary hyperoxaluria type 1, who after 3 years and 6 months of maintenance hemodialysis, and despite intensification of the dialytic treatment, developed severe livedo reticularis in her extremities leading to ischemic cutaneous ulcerations, necessitating continuous intravenous infusion of narcotics for pain control. She received a liver transplant after native hepatectomy. However, due to positive crossmatch, she could not receive a kidney from that donor. After transplantation, following serial serum oxalate levels, the hemodialysis regimen was safely reduced from 4 h daily to 3 h three times weekly. Over the course of 6 weeks after liver transplantation, her livedo reticularis resolved, the ischemic ulcers markedly improved, she was weaned off all pain medications, and her erythropoietin-resistant anemia resolved. Our results suggest that in patients with primary hyperoxaluria type 1, who have received a liver transplant and are on maintenance hemodialysis, after serial serum oxalate determinations, some may safely be changed to a thrice-weekly maintenance hemodialysis regimen. Moreover, with this regimen the complications of systemic oxalosis can reverse.- - - - - - - - - - ranking = 0.28571428571429keywords = ulcer (Clic here for more details about this article) |
5/626. Flank ulcer in a patient with primary antiphospholipid syndrome.A 32-year-old woman had a recurrent shallow ulcer on the flank. A biopsy specimen showed thromboses in the dermal vessels and she was found to have circulating antiphospholipid antibody with no associated systemic disease. A clean ulcer developed on the flank of a patient with primary antiphospholipid syndrome is considered to be a rarely encountered/unusual presentation of this syndrome.- - - - - - - - - - ranking = 0.85714285714286keywords = ulcer (Clic here for more details about this article) |
6/626. Familial primary cryofibrinogenemia.BACKGROUND: To our best knowledge this is the second case ever described of familial primary cryofibrinogenemia (CFG). patients: A 29-year-old Moroccan female and two of her three children suffered from painful purpura, slow healing small ulcerations and edema of both feet during the winter season. Laboratory investigations revealed the presence of cryofibrinogen in their blood plasma. All three patients were otherwise healthy and no associated disease could be demonstrated. CONCLUSIONS: The diagnosis of CFG has to be considered in patients with livedo reticularis, edema, painful purpura and slow healing ulcera after cold exposure. Cryofibrinogen-precipitates in the blood plasma have to be determined. Because secondary CFG occurs much more frequently than the primary form, it is important to rule out associated diseases through extensive physical examination and laboratory investigations. This communication also stresses the importance of a through family history of patients with CFG. An autosomal dominant mode of inheritance is supposed.- - - - - - - - - - ranking = 0.28571428571429keywords = ulcer (Clic here for more details about this article) |
7/626. Treatment of painful skin ulcers with topical opioids.Recent research suggests that opioid receptors on peripheral nerve terminals may play an important role in the modulation of pain. Clinical applications of this knowledge have been rather slow to evolve. We describe a consecutive series of nine patients with painful skin ulcers due to a variety of medical conditions. All patients were treated with a topical morphine-infused gel dressing. Seven of the nine patients experienced substantial and another experienced a lesser (but still significant) degree of analgesia. The ninth reported no relief, but his wound was not an open ulcer. Discussion centers on the practical application of this development in the large number of patients with painful skin lesions.- - - - - - - - - - ranking = 0.85714285714286keywords = ulcer (Clic here for more details about this article) |
8/626. Primary cutaneous cryptococcosis in an hiv-negative patient.We report a case of primary cutaneous cryptococcosis in an hiv-negative patient, who presented with painless, ulcerated lesions involving the right forearm (fingers and elbow), which developed over 45 days. On the basis of the clinical appearance, serological and cultural examinations were performed to confirm the diagnosis; the histological evaluation of a skin biopsy showed an acute inflammatory infiltrate containing several PAS Cryptococci. Subsequently, the patient was treated with fluconazole (400 mg/day for 10 days, then a maintenance therapy of 200 mg/day); after one month, the cutaneous lesions were remarkably improved, but, although a series of further laboratory and clinical examinations was scheduled, the patient repeatedly refused any other re-evaluation, and he was lost from follow-up.- - - - - - - - - - ranking = 0.14285714285714keywords = ulcer (Clic here for more details about this article) |
9/626. Chronic factitial ulcer of chin cured by endodontic (root-canal) surgery for underlying periapical abscess.In a determined search for the cause of a "factitial" ulcer of the jaw, consultation with 3 dentists was required before an underlying periapical abscess was discovered. Within 3 months of endodontic surgery, this ulcer of 12 years duration had completely healed and remains healed. Too often dental infection is neither suspected nor detected as a cause of skin disease.- - - - - - - - - - ranking = 0.85714285714286keywords = ulcer (Clic here for more details about this article) |
10/626. Distant and delayed mitomycin C extravasation.mitomycin C is a vesicant chemotherapeutic agent used to treat solid tumors. Its ability to cause delayed and remote tissue injury after intravenous administration is reported in the literature. Two cases of delayed and distant mitomycin C extravasation injury occurred in our institution. In both patients, no evidence of acute extravasation was visible during or immediately after administration. Within 48 hours, one patient reported erythema, burning, and pain in the hand contralateral to the administration site. The second patient developed three distinct ulcerated lesions on her forearm within 6 weeks of receiving the agent. The lesions, located at sites of venipunctures, occurred 12-15 cm proximal to the site of mitomycin infusion. Because the drug has the potential to cause such unusual and unanticipated tissue injuries, health care professionals and patients should be aware of this hazard.- - - - - - - - - - ranking = 0.14285714285714keywords = ulcer (Clic here for more details about this article) |
