Methicillin-resistant Staphylococcus aureus in community-acquired pyoderma.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an important nosocomial pathogen. It can also cause community-acquired infections. Indian reports about MRSA in community-acquired infections are rare. AIM: To evaluate the rate of MRSA in community-acquired pyoderma and the nasal colonisation with S. aureus in such patients. METHODS: Two hundred and fifty patients with community-acquired pyoderma, who attended outreach camps around Mangalore, south India between January 2000 and July 2001, were studied. Swabs collected from the skin lesions and anterior nares were inoculated onto blood agar and MacConkey's agar. Antimicrobial sensitivity testing was performed using Kirby-Bauer disk diffusion, agar dilution, and agar screen. RESULTS: Of 250 pyoderma cases, S. aureus was isolated from 202 (80.8%) patients. Twenty-two (10.9%) S. aureus isolates were methicillin resistant, 179 (88.6%) were resistant to penicillin, and 114 (56.4%) were resistant to erythromycin. S. aureus colonization in the anterior nares was observed in 136 (54.4%) cases, 11.8% of which were MRSA. Antibiograms of clinical isolates of S. aureus matched with nasal isolates in 99 (49%) cases. CONCLUSION: The emergence of MRSA in the community is a warning. A high nasal carriage rate may contribute to recurrent pyoderma. A correct antimicrobial policy and the avoidance of inappropriate antimicrobial usage are mandatory to reduce the spread of MRSA in the community.

Pyoderma gangrenosum in infants and children.

Pyoderma gangrenosum is an uncommon ulcerative skin disorder that occurs in all age groups. Approximately 4% of patients are infants and children. There are several notable differences between the childhood and adult manifestations of the disease, including the distribution of lesions and associated disorders. We reviewed the childhood cases (< or = 18 yrs of age) of unequivocal pyoderma gangrenosum in the English literature and tabulated the trends in clinical features, associated disorders, and therapy. We report our 3-week-old patient, the youngest documented case. Of the 46 patients, only 4 were less than 1 year of age. A systemic illness was present in 74% of the older children, most commonly, ulcerative colitis. Only one infant had an associated problem (HIV+) at the time of onset. Infants appear to have an unusual distribution of perianal and genital lesions not often described in other age groups. Our review suggests that pyoderma gangrenosum in children has a similar clinical appearance to that in adults. It is associated with some of the same underlying disorders, but with different frequencies. The distribution of lesions in children is similar, often involving the lower extremities, but pyoderma gangrenosum of the head and face appears to be more common in children. Infants may have ulcers in genital and perianal areas. The most frequently prescribed treatment for children is systemic corticosteroids, which generally are very effective.

Dramatic improvement of pyoderma gangrenosum with infliximab in a patient with PAPA syndrome.

Infliximab, a chimeric antitumor necrosis factor alpha monoclonal antibody (anti-TNF alpha), has been recently shown to have a beneficial effect on pyoderma gangrenosum associated with inflammatory bowel disease. Patients with the syndromic triad of pyogenic sterile arthritis, pyoderma gangrenosum, and acne, an autoinflammatory process caused by mutations in the CD2 binding protein-1 (CD2BP1) gene, can have severe pyoderma gangrenosum. We describe a 14-year-old patient with this syndrome who was unresponsive to multiple therapies. A dramatic improvement in his pyoderma gangrenosum was observed after one infusion of infliximab, and a second infusion led to its resolution. Our observation extends the therapeutic use of infliximab to this component of PAPA syndrome.

[Ulceration of the scalp: a unique manifestation of pyoderma gangrenosum].

Pyoderma gangrenosum is a chronic, noninfectious, ulcerating cutaneous disease of unknown etiology usually presenting with multiple lesions on the legs and trunk. Solitary lesions in other locations are rare and therefore hard to diagnose. A 78-year-old and a 81-year-old woman with extensive scalp necrosis were both diagnosed as pyoderma gangrenosum after exclusion of other differential diagnostic possibilities. The separate diagnosis of malignant pyoderma for this disease state no longer seems justified. Scalp necrosis is infrequently seen in dermatological patients; most previous reports describe it in giant cell arteritis. Other differential diagnoses include viral, bacterial and mycotic infections as well as erosive pustular dermatosis of the scalp. In conclusion, we again draw attention to unilesional pyoderma gangrenosum of the scalp as a rare disease entity. Immunosuppressive drugs are an effective treatment modality.

Antibiotic responsive ulcerative dermatoses in German Shepherd Dogs with mucocutaneous pyoderma.

Mucocutaneous pyoderma is a disease of unknown aetiology affecting mucocutaneous skin and is responsive to antibacterial therapy. It is reported to affect the lips, nasal planum, nares, perioral skin and less commonly, the eyelids, vulva, prepuce and anus. Three cases of mucocutaneous pyoderma are presented. Two of the cases showed ulcerative lesions in the inguinal and axillary regions in addition to more typically reported lesions. Two of the dogs had concurrent atopic dermatitis and the third had clinical signs suggestive of hyper-sensitivity disease. The clinical and histopathological features, differentiation of mucocutaneous pyoderma from discoid lupus erythematosus, and long-term management of mucocutaneous pyoderma are discussed.

Pyoderma gangrenosum and ulcerative colitis.

The relationship of pyoderma gangrenosum and ulcerative colitis remains uncertain. We investigating 14 patients with pyoderma gangrenosum by colonoscopy with multiple biopsies. Six patients had ulcerative colitis and all of these had disease affecting the whole colon. There were no correlations between exacerbations of the colitis and the onset or course of pyoderma gangrenosum. The remaining eight patients with pyoderma gangrenosum had no other disease and they were found to be significantly older than those patients with coexisting colitis (P less than 0.002).

Atypical bullous pyoderma gangrenosum associated with myeloid malignancies.

Atypical bullous pyoderma gangrenosum was diagnosed during the course of a myeloid malignancy in three patients. One patient had chronic myeloid leukaemia, one acute myeloid leukaemia, and the third, refractory anaemia with excess of blasts. This atypical form of pyoderma gangrenosum has been specifically associated with myeloid malignancies. The atypical appearance of the skin lesions and the clinical context in which they arose caused the true diagnosis to be delayed in all cases. Treatment with steroids was associated with rapid healing of the skin lesion. The histopathological changes in the skin biopsy specimens from these cases were non-specific, and although the histology was considered to be atypical of pyoderma gangrenosum in one case, the unusual features could be attributed to the patient's neutropenia. (Skin biopsy was performed to exclude other specific pathology). Atypical bullous pyoderma gangrenosum is an uncommon association of the myeloid malignancies. It may remain unrecognised and should be considered more often.

Erythema nodosum and pyoderma gangrenosum in 50 patients with Crohn's disease.

Erythema nodosum and pyoderma gangrenosum may occur in Crohn's disease. In the present evaluation of consecutive patients with Crohn's disease spanning more than two decades, erythema nodosum was seen in 45 patients and pyoderma gangrenosum was seen in seven patients. Forty-one of 566 women (7.2%) and nine of 449 men (2.0%) were affected. Of these, 45 (4.4%) had erythema nodosum and seven (0.7%) had pyoderma gangrenosum, including two (0.2%) with both dermatological disorders at different times during their clinical courses. Recurrent erythema nodosum was also detected in nine patients (20%) including eight women, while recurrent pyoderma gangrenosum was seen in two patients (28.6%). There was an age-dependent effect on the appearance of erythema nodosum in women, with the highest percentages seen in those younger than 20 years of age. Detection rates for erythema nodosum in women only approached the low men's rates in Crohn's disease at older than 40 years of age. Most patients with these dermatological disorders had colonic disease with or without ileal involvement as well as complex disease, usually with penetrating complications. The present study documents a sex-based and age-dependent effect on the clinical expression of erythema nodosum in Crohn's disease. This suggests that some components of the inflammatory process in Crohn's disease may be modulated by estrogen-mediated events, particularly in adolescents and young adults.

Pyoderma gangrenosum as an early revelator of acute leukemia.

Bullous pyoderma gangrenosum is an atypical, more superficial variety of the classical pyoderma and is often associated with myeloproliferative disorders. We present the case of a patient who presented initially with subcutaneous nodules and who developed bullous lesions afterwards. Histological evaluation showed the presence of neutrophilic infiltrates in both lesions. A few months after the diagnosis of bullous pyoderma gangrenosum, an underlying leukemia was revealed. Our case illustrates the importance of regular blood and bone marrow examinations in patients with atypical bullous pyoderma gangrenosum, resulting in a rapid diagnosis of the underlying disease.

Topical treatment with 1% sodium cromoglycate in pyoderma gangrenosum.

BACKGROUND: Pyoderma gangrenosum is an uncommon skin disease usually treated with systemic drugs, most frequently corticosteroids. Isolated topical treatment is usually considered unsatisfactory. OBJECTIVE: To evaluate the effect of topical 1% sodium cromoglycate solution on pyoderma gangrenosum in 5 patients 25-30 years of age. METHODS: 5 patients, including 2 under systemic steroid treatment, hospitalized in our department from 1992 to 1993 because of pyoderma gangrenosum, were treated with topical 1% sodium cromoglycate solution. Systemic corticosteroids were further added in 2 patients whose initial improvement was inadequate. RESULTS: Initial improvement was noted in all 5 patients after 3-7 days of sodium cromoglycate treatment. Complete healing of the ulcers occurred within 5-8 weeks. CONCLUSIONS: Topical treatment with sodium cromoglycate can be effective as adjunctive or sole treatment in pyoderma gangrenosum.

Multiple aseptic pulmonary nodules with central necrosis in association with pyoderma gangrenosum.

Pulmonary manifestations of pyoderma gangrenosum are relatively rare. We report the case of a 45-year-old patient with multiple pulmonary nodules with central necrosis as assessed by CT scan. The patient had a 4-year history of pyoderma gangrenosum with only minor skin manifestations. A CT-guided, fine-needle biopsy of the lung revealed a nonspecific, inflammatory, aseptic necrotic process, which was comparable to the skin biopsy of one pyoderma lesion. Following the initiation of oral prednisolone therapy, a rapid resolution of the pulmonary nodules occurred. We conclude that pulmonary nodules represent a rare pulmonary manifestation of pyoderma gangrenosum.

Pyoderma gangrenosum triggered by alpha2b-interferon in a patient with chronic granulocytic leukemia.

Pyoderma gangrenosum is a neutrophilic dermatosis that is frequently associated with malignancies such as myeloproliferative disorders. The development of this dermatologic disorder is thought to be mediated by immunological mechanisms. A case of pyoderma gangrenosum associated with the administration of alpha2b-interferon (alpha2b-IFN) in a patient with chronic granulocytic leukemia is described. Discontinuation of alpha2b-IFN and the administration of cyclosporin A and prednisone resulted in cure of the pyoderma gangrenosum. Serum levels of tumor necrosis factor, interleukin-6 and soluble interleukin-2 receptor increased when the cutaneous lesions appeared and returned to normal levels when the lesion healed. We believe that this is the first reported case of pyoderma gangrenosum associated with alpha2b-IFN therapy.

Intestinal Behcet's disease with pyoderma gangrenosum: a case report.

We report here a very rare case of intestinal Behcet's disease with pyoderma gangrenosum. A 16-year-old woman who was diagnosed with intestinal Behcet's disease by the presence of cutaneous pathergy together with two major criteria (oral and genital aphthoses) and one minor criterion (gastrointestinal manifestations), was referred to our hospital with a left lower leg ulcer and abdominal pain in September 1989. Colonoscopy demonstrated flare-up colitis involving the entire colon. Her lower leg lesion was a painful destructive ulcer with an irregular margin and a ragged overhanging edge. Based on these clinical and laboratory findings, we diagnosed her cutaneous ulcer as pyoderma gangrenosum developing with exacerbated intestinal Behcet's disease. Her cutaneous and intestinal lesions were poorly controlled though she received oral prednisolone treatment for a month. Because of aggravated abdominal symptoms with peritoneal irritation, we performed total colectomy in November 1989. The resected specimen was histologically compatible with intestinal Behcet's disease showing severe inflammation with deep ulcerations and neutrophil accumulation. Subsequently, pyoderma gangrenosum rapidly improved. This clinical course may suggest the close relationship between pyoderma gangrenosum and intestinal Behcet's disease.

Epidemiologic studies among Amerindian populations of Amazônia. I. Pyoderma: prevalence and associated pathogens.

Pyoderma was studied among a representative sample of the residents of four remote Amerindian villages, Amazonas State, Brazil, during July-August 1976. The overall prevalence among the 775 inhabitants examined was 11%, with little intervillage variation. When the attack rates for the entire sample population were calculated by 5-year age intervals, the 0- to 4-year-olds had the highest rate, 31%. The highest prevalence, 38%, was found among 3-year-olds. Attack rates were not apparently related to sex. Cultures which were taken from representative pyoderma lesions from people in the four survey villages and from three additional villages were studied by a modified delayed culture technique for recovery of gram-positive pathogens from silica-gel desiccated swabs. Group A and group G B-hemolytic streptococci, coagulase positive Staphylococcus aureus, and Corynebacterium diphtheriae were isolated. Group A S. pyogenes was most commonly found, occasionally as the sole pathogenic species. No nephritogenic M-types were found, although most isolates were not M-typable. The T-types found corresponded to those previously reported as being pyoderma-associated. Most pyoderma-associated C. diphtheriae isolates were non-toxigenic. Biotypes gravis and mitis were equally represented.

[Cutaneous pyoderma gangrenosum with hepatosplenic localization and monoclonal gammapathy. A case report].

Pyoderma gangrenosum is an ulcerative disease of the skin. The histopathological lesions are nonspecific, characterized by a diffuse neutrophilic infiltrate in the dermis. Pyoderma gangrenosum is associated with inflammatory, digestive or articular disease, or acute or chronic hemotology disorders in 50% of the cases, more rarely with monoclonal gammapathy. A visceral localization of pyoderma gangrenosum is rare, simulating a systemic disease or an underlying neoplasia. We report a case of cutaneous pyoderma gangrenosum with splenic and hepatic localizatios associated with an IgG monoclonal gammapathy. We emphasize the efficacy of immunosuppressor treatment and the importance of long-term monitoring of these patients.

[Pyoderma gangrenosum: report of 11 cases].

BACKGROUND: Pyoderma gangrenosum is an ulcerative disease of the skin of unknown cause and generally associated to systemic illnesses. It requires an aggressive systemic therapy and there is little information about its long term evolution. AIM: To report the clinical features of patients with pyoderma gangrenosum. PATIENTS AND METHODS: Eleven patients (10 female) aged 27 to 81 years old with pyoderma gangrenosum are reported. All had a pathological study. Patients were followed up for a mean of 60 months. RESULTS: The lesions were located in the lower limbs in 8 patients. Pathological study showed neutrophyl infiltrates in nine patients. Three patients had inflammatory bowel disease [corrected]. During the follow up, the disease recurred in multiple occasions, in six patients, after treatment with steroids or sulphones, and one patient has had permanently active lesions. CONCLUSIONS: Pyoderma gangrenosum appears mostly in the lower limbs and has a high recurrence rate.

Familial ulcerative pyoderma gangrenosum: a report of 2 kindred.

Pyoderma gangrenosum is a rare, chronic ulcerative skin disease. It is a diagnosis of exclusion, after ruling out other causes of cutaneous ulceration. The etiology of pyoderma gangrenosum is poorly understood but is likely multifactorial. We describe 2 families affected by ulcerative pyoderma gangrenosum. This familial clustering suggests a possible genetic role in the development of pyoderma gangrenosum in some cases.

[Pyoderma gangrenosum and orbital pseudotumor].

Pyoderma gangrenosum belongs to the chronic, neutrophilic and necrotic dermatoses. These very painful, inflammable and purulent skin-ulcers often arise after injury or surgical intervention. About half of the patients suffer from systemic disease, for example hematological, gastrointestinal or rheumatic diseases. Our report includes a 77-year-old female with a multilocular emergence of pyoderma gangrenosum following surgery for an orbital pseudotumor. An additional lesion was detected on her anterior neck. Because the possibility of wound-infection was suspected, the lesion was treated locally and with a systemic antibiotic therapy. After this treatment the condition of the wound deteriorated. Upon dermatological examination, pyoderma gangrenosum was identified and a immunosuppressive therapy with corticosteroids and cyclosporin was initiated. As a result of this treatment the lesion healed slowly--with the formation of typical, atrophic and reticular scars. A connection between the pyoderma gangrenosum and the orbital pseudotumor can, on the basis of similar clinical and structural characteristics, not be excluded. A related disease was not diagnosed in this patient. Recurrence can be predicted in patients who have had skin injuries, therefore strict observation is required.
