Preparing the wound bed 2003: focus on infection and inflammation. (9/93)

Wound bed preparation is the promotion of wound closure through diagnosis of the cause, attention to patient-centered concerns, and correction of systemic and local factors that may delay healing. To enhance the evidence base that may be lacking, a review of relevant literature was conducted and combined with input from the International Wound Bed Preparation Advisory Board and the Canadian Chronic Wound Advisory Board to create an updated examination of practices. A template based on expert opinion of the clinical actions corresponding to each step in the paradigm of preparing the wound bed is presented and the effects of local factors (tissue debridement, infection or inflammation, moisture balance, and edge effect [TIME]) are discussed. This review differentiates increased bacterial burden/infection in the superficial and deep wound bed compartments from inflammation and provides a topical approach to treatment. Inflammatory conditions causing leg ulcers, including pyoderma gangrenosum and vasculitis are reviewed. The topical combination of silver with absorptive dressings has led to new therapeutic options for increased bacterial burden in the surface wound compartment. A compilation of the available systematic reviews for the treatment of infection has been included as a background for the expert opinion.  (+info)

Clinical manifestations of pyoderma gangrenosum associated with inflammatory bowel disease. (10/93)

BACKGROUND: Pyoderma gangrenosum is an uncommon ulcerative cutaneous condition associated with inflammatory bowel disease. PG occurs rarely in IBD patients and there are insufficient data on the clinical manifestations of this disease with IBD. OBJECTIVE: To determine the incidence, clinical manifestations and treatment of PG in patients with IBD and the connection to IBD, its activity and extent. METHODS: All patients hospitalized with IBD at a university hospital during a 20 year period were evaluated for the occurrence of PG. RESULTS: Of 986 patients hospitalized for IBD 6 suffered from PG (0.6% incidence). Their average age was 37 with equal sex distribution and equal distribution of Crohn's disease and ulcerative colitis. PG appeared 6.5 years on average after diagnosis of IBD in all patients. The development of PG correlated with significant clinical exacerbation of IBD, the majority having active colitis at the onset of the PG. Extraintestinal manifestations of IBD occurred in half the patients (sacroillitis, peripheral arthritis and erythema nodosum). Pathergy was not elicited in any patients. Four patients had multiple skin lesions, frequently on the lower extremities. Diagnosis was made by skin biopsy in four patients. There was little correlation between amelioration of IBD and the skin lesions. Treatment consisted of high dose steroids and immunomodulatory drugs (cyclosporine, azathioprine and dapsone) in conjunction with topical treatment. CONCLUSIONS: PG is a rare extra-intestinal manifestation of IBD that coincides with the exacerbation of the intestinal disease but does not always respond to treatment of the bowel disease.  (+info)

Symmetrical, painful ulceration of the lower limbs in a vascular surgery ward: a diagnostic challenge. Pyoderma gangrenosum associated with IgG-kappa paraproteinaemia. (11/93)

We describe a 61-year-old patient who had been suffering from chronic ulcers of both legs for 18 months. Initially, his condition was diagnosed as ischaemic because of an ankle-brachial index of 0.6, as confirmed by additional angiography. A successful femoro-infragenual bypass procedure was performed, but the ulcers increased in size and number. He was then extensively analysed for a possible (macro)vascular origin of his symptoms. Angiographic analysis of both legs showed no arterial stenosis or occlusion. Despite the extensive experience of the vascular surgeons with leg ulcers, consultations by internal medicine, vascular medicine and dermatology, and tissue examination by our pathologists, pyoderma gangrenosum was not recognised. During a multidisciplinary meeting one of the specialists, to whom the lesions were shown, immediately considered the diagnosis on clinical grounds. The additional finding of IgG-kappa paraproteinaemia and improvement of the ulcers on treatment with corticosteroids were consistent with the diagnosis. Although the majority of patients on the vascular surgery ward have ulcers caused by ischaemia or a combined arterial/venous origin, another (rare) cause, namely pyoderma gangrenosum in association with IgG-kappa paraproteinaemia without the presence of multiple myeloma, should be taken into account.  (+info)

Metastatic Crohn's disease mimicking genital pyoderma gangrenosum in an HIV patient. (12/93)

The differential diagnosis of ulcerative genital lesions in patients with high risk sexual habits can be a challenge even for dermatologists. We present the case of a 27-year-old HIV-positive male with a history of recalcitrant genital ulcers. Microbiology studies were negative. A skin biopsy and a sample from a perineal fistula showed granulomatous infiltrates. The patient was treated with prednisone, metronidazole and aminosalicylates, showing complete resolution of the lesions in a few weeks. The clinical picture and histological findings are consistent with the diagnosis of cutaneous metastatic Crohn's disease. Although infrequent, metastatic Crohn's disease should be suspected in cases of recalcitrant ulcerative conditions, even in the absence of intestinal disease.  (+info)

Cutaneous manifestations of systemic disease. (13/93)

BACKGROUND: While most patients who present with a rash have no associated systemic illness, many systemic illnesses have skin manifestations at some stage. OBJECTIVE: This article uses case vignettes to illustrate a problem oriented approach to five commonly presented skin conditions that have common and varied systemic associations. A logical sequence of management for each case is provided. DISCUSSION: Often the skin manifestations of systemic disease are vague and nonspecific such as the toxic erythema that might follow a viral infection or a drug eruption. Sometimes it is the systemic manifestations that are vague and nonspecific, while the skin manifestations are highly specific and define the illness. There is currently no useful classification for cutaneous manifestations of systemic disease.  (+info)

Pyoderma gangraenosum associated with autoimmune thyreopathy and hyperandrogenic syndrome. (14/93)

An unusual clinical appearance and course of pyoderma gangraenosum (PG) in a 35-year-old woman is presented. Signs of both the ulcerative and vegetative forms of PG were expressed. The association of two systemic diseases, the autoimmune thyreopathy and the hyperandrogenic syndrome were observed in a female. The recommended conventional therapy for PG: corticosteroids, antibiotics, cyclosporine and cyclophosphamide yielded a poor response, whereas after thyroidectomy and reaching an euthyroid state the symptoms receded. This close association of PG and autoimmune thyreopathy supports the autoimmune concept of PG.  (+info)

Asymptomatic inflammatory bowel disease presenting with mucocutaneous findings. (15/93)

Although inflammatory bowel disease (IBD) typically presents with gastrointestinal complaints, mucocutaneous lesions are commonly associated and can precede gastrointestinal symptoms, thereby alerting the clinician to the diagnosis of IBD before the onset of gastrointestinal symptoms. Nine children are reported who had no gastrointestinal symptoms suggestive of IBD but presented with mucocutaneous findings of IBD and were subsequently diagnosed with Crohn's disease or ulcerative colitis based on characteristic features on gastrointestinal endoscopy and/or biopsies. The majority of the patients had oral and perianal lesions. We believe that IBD is a common etiology for persistent oral lesions in the pediatric population. In addition to a good history, children with unexplained oral mucous membrane lesions should have an examination of the rectal and genital mucosa as well as tests for complete blood count, iron levels, sedimentation rate, albumin, and occult blood in the stool with endoscopy and biopsies to rule out IBD if indicated.  (+info)

Important cutaneous manifestations of inflammatory bowel disease. (16/93)

Inflammatory bowel disease (IBD) has many extraintestinal manifestations. Cutaneous manifestations are usually related to the activity of the bowel disease but may have an independent course. Anyone presenting with IBD should be examined for cutaneous manifestations. Pyoderma gangrenosum is a severe painful ulcerating disease that requires moist wound management and, in the absence of secondary infection, systemic corticosteroids, cyclosporine, or both. Infliximab may also be used. Erythema nodosum is a common cause of tender red nodules of the shins. Management includes leg elevation, NSAIDs, and potassium iodide. Oral manifestations of IBD include aphthous stomatitis, mucosal nodularity (cobblestoning), and pyostomatitis vegetans. Treatment should be directed both at the cutaneous lesions and at the underlying systemic condition.  (+info)
