Staphylococcus aureus re-colonization in atopic dermatitis: beyond the skin.

Patients with atopic dermatitis (AD) are often heavily colonized by Staphylococcus aureus, which adversely affects eczema severity. Strategies to control S. aureus in AD include antibiotic and or antiseptics. However long-term efficacy is unclear. In this study we consider extra-cutaneous factors that may cause S. aureus re-colonization in adult AD. Twenty-one patients with AD were recruited and were assessed for: duration of AD, use of topical or oral antibiotic within the preceding 3 months, the number of hospital admissions during the preceding year and current treatment. The types of topical treatments used, vehicle, container and the expiry dates were also recorded. The severity of AD was assessed by SCORAD index. Microbiological assessment for S. aureus carriage from affected skin, anterior nares, emollient and topical steroid was undertaken using culture, Staphaurex test and antibiotic resistance. Of the patients 86% had S. aureus colonization. The median SCORAD score were greater in those colonized with S. aureus (P = 0.02) and those with contaminated treatments (P = 0.05). Prior antibiotic treatment, prior hospital admission and nasal carriage did not influence the median SCORAD. Three extra-cutaneous mechanisms by which S. aureus can re-colonize the skin were identified: antibiotic resistance, nasal carriage and treatment contamination.

Successful treatment of pyoderma gangrenosum with topical 0.5% nicotine cream.

Pyoderma gangrenosum is potentially a devastating and destructive disorder. There is no uniformly effective or specific therapy for pyoderma gangrenosum. Previous reports of nicotine therapy for pyoderma gangrenosum have suggested it to be efficacious. Unfortunately, previous reports were restricted by the use of commercially available preparations of nicotine, either as a gum or patch formulation. We have used topical nicotine 0.5% w/w cetamacrogol formula A cream that enables direct application onto the lesion, as well as dose and concentration variation. Two patients with pyoderma gangrenosum treated with topical nicotine 0.5% w/w cetamacrogol formula A cream are described here, both of whom had dramatic clinical resolution of their pyoderma gangrenosum.

Intestinal bypass syndrome presenting as erythema nodosum.

Intestinal bypass was a popular surgical procedure for morbid obesity resulting, on average, in a 50 kg weight loss. We describe a 66-year-old woman who underwent the procedure 12 years earlier and subsequently presented with recurrent episodes of erythema nodosum-like lesions. Further investigations revealed hyperoxaluria, renal failure, deficiency of fat-soluble vitamins (causing night blindness, osteomalacia and easy bruising) and anaemia. Antibiotics led to only temporary remission and, as with 24-30% of similar cases, she underwent surgical reversal to prevent the complications from worsening.

Wound-related osteomyelitis: a case of containment not cure.

Community nurses need to be aware that some patients with osteomyelitis are treated with antibiotics alone. Such patients often have co-morbidities and quality of life issues that directly impact on the decision to treat osteomyelitis surgically. However, adopting a conservative approach to osteomyelitis management is associated with an increased risk of osteomyelitis recurrence. The rationale for managing chronic wound-related osteomyelitis with antibiotics is discussed. Community nurses caring for patients that have received antibiotics alone to treat osteomyelitis need to be aware of the potential for osteomyelitis recurrence and how to make the diagnosis.

Science, medicine and the future: healing chronic wounds.

Greater interest in wound healing is needed to ensure higher standards of basic care. Precise identification of the systemic, local, and molecular factors underlying the wound healing problem in individual patients should allow better tailored treatment. Allogeneic skin grafting and bioengineered skin equivalents are being used successfully in patients with venous leg ulcers and diabetic patients with foot ulcers.

An aggressive treatment for aggressive digital papillary adenocarcinoma.

Aggressive digital papillary adenoma (ADPA) and adenocarcinoma (ADPAca) are adnexal tumors that are not often recognized because of their rarity. We present a rare case of ADPAca involving the left middle finger of a 43-year-old man. Histopathological features of ADPAca are distinct from those of other eccrine sweat gland tumors; however, ADPAca may be misdiagnosed particularly for a metastasis of papillary adenocarcinoma originating in the colon, thyroid, or breast. Clinicopathological correlation is essential to ule out a possible risk of metastatic carcinoma of the skin. Recognition of these tumors is important because of a potential risk of local recurrence nd distant metastases. Aggressive surgical treatment consisting of digit amputation is advocated in the treatment of ADPAca.

Rifampicin-induced lupus erythematosus.

Rifampicin has been prescribed throughout the world for over 20 years, yet only four cases of rifampicin-induced lupus erythematosus (LE) have been reported. Rifampicin-induced LE is associated with combination therapy with clarithromycin or ciprofloxacin. These drugs are all metabolized through the cytochrome P450 liver enzyme system and combined usage may lead to higher rifampicin blood levels. Drug-induced LE differs from systemic LE; cutaneous manifestations, although uncommon, are an important clue to the diagnosis. We report a case of rifampicin-induced LE presenting with florid cutaneous features.

Malignant atrophic papulosis (Degos' disease): clinicopathological correlations.

Malignant atrophic papulosis (MAP) is a rare disease characterized by pathognomonic cutaneous lesions and frequently fatal systemic involvement. Dermatologists should have a high index of suspicion for systemic complications in a patient presenting with MAP. We report a case of malignant atrophic papulosis to highlight the clinicopathological features and review this important dermatological diagnosis.

Managing gravitational eczema and allergic contact dermatitis.

Venous leg ulceration is a common chronic problem in the community, and gravitational eczema is a common complication of it. The presence of gravitational eczema can lead to further ulceration and may also impair wound healing. Treatment often requires more than one topical preparation, to gain control and prevent relapse. Knowledge of the benefits and risks of these therapeutic modalities is essential, in this article we aim to provide a practical approach to the treatment of gravitational eczema. We also discuss allergic contact dermatitis, a common complication of gravitational eczema.

Severe digital necrosis in an elderly patient with heterozygous factor V Leiden mutation.

We report an 81-year-old female with a heterozygous factor V Leiden mutation who developed purpura fulminans. Digital necrosis, a characteristic clinical feature of purpura fulminans was prominent. Purpura fulminans is more common in children and adult cases are rare. Of eight reported cases of purpura fulminans resulting from a heterozygous factor V Leiden mutation recorded in the literature, only two were in adults: 40 and 42 years of age, respectively. This is the first report of this condition arising in a patient in her eighties.

An unusual case of purpuric erythropoietic protoporphyria.

Erythropoietic protoporphyria (EPP) is the most common of the erythropoietic porphyrias. Recent advances in diagnostic laboratory tests have led to the discovery of a number of previously undiagnosed cases. We describe a case of EPP presenting late with a purpuric eruption and discuss the pathogenesis and significance of purpura in EPP.
