Inflammatory epidermolysis bullosa acquisita mimicking toxic epidermal necrolysis and dermatitis herpetiformis

We report a patient with a spectrum of clinical features simulating toxic epidermal necrolysis, bullous erythema multiforme and later, dermatitis herpetiformis (DH). The histological features were suggestive of DH, bullous pemphigoid (BP) and epidermolysis bullosa acquisita (EBA). Direct immunofluorescence results suggested BP or EBA. Indirect immunofluorescence on salt-split skin and immunoblotting analysis on normal human dermal extracts gave results that were diagnostic for EBA.

Defining cancer risk in dermatomyositis. Part II. Assessing diagnostic usefulness of myositis serology

In part 1 of this review, we examined the evidence behind the association between idiopathic inflammatory myopathies (IIM) and cancers. In view of the well-recognized association between cancer and myositis (hence the term cancer-associated myositis, or CAM), clinicians responsible for the management of patients with myositis must make important decisions regarding how intensively they undertake searches for malignancy. Clinicians must also decide how often such searches are repeated, and again how intensively, to optimize both cancer detection and treatment, and thus patient survival. As the risks of CAM are greatest in dermatomyositis, this is an issue of obvious importance to dermatologists. In this second of two reviews, we examine the role of autoantibodies as potential predictors of cancer risk in patients with IIM.

Efficacy of topical tacrolimus 0.3% in clobetasol propionate 0.05% ointment in therapy-resistant cutaneous lupus erythematosus: a cohort study

BACKGROUND

Despite a range of available topical and systemic therapies, treatment of cutaneous lupus erythematosus (CLE) can be challenging. Objectives. To evaluate the efficacy of a specially formulated preparation of tacrolimus 0.3% in clobetasol propionate 0.05% ointment (TCPO) in the treatment of CLE.

METHODS

Case notes of 13 patients with treatment-resistant CLE (11 discoid LE, 1 systemic LE and 1 subacute cutaneous LE) who had used twice-daily TCPO (TCPO group) were reviewed. These were compared with five similar patients with resistant CLE who had been given 0.1% tacrolimus ointment alone (TO group).

RESULTS

In the TCPO group (mean treatment duration 20 months, range 1-72), a good or excellent response was seen in five and six patients, respectively; one patient showed slight improvement. Telangiectasia and acne were observed in two patients. No systemic side-effects were noted. In the TO group (mean treatment duration 6 months, range 1-24), one patient showed good improvement and two showed slight improvement.

CONCLUSION

The results of our small retrospective study suggest that TCPO may be more effective than either 0.1% tacrolimus or clobetasol propionate 0.05% ointment monotherapy in the treatment of recalcitrant CLE. Randomized controlled trials are needed to confirm these preliminary findings.

Defining cancer risk in dermatomyositis. Part I

The idiopathic inflammatory myopathies (IIMs) comprise polymyositis, myositis overlapping with another connective tissue disease, dermatomyositis (DM) and inclusion-body myositis (IBM). IIMs are characterized by the presence of proximal muscle weakness, increased levels of muscle-specific enzymes, specific electromyographic abnormalities, and the presence of inflammatory cell infiltrates in skeletal muscle. Clinical, serological and histological criteria can be used to define individual IIM subtypes. In the first of this two-part review series, we examine the evidence for the existence of cancer-associated myositis (CAM), and in part 2, we discuss recent discoveries that provide insight into identification of patients with DM, who may be most at risk of developing CAM.

Outcomes of treatment of nine cases of recalcitrant severe hidradenitis suppurativa with carbon dioxide laser

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic and often a recalcitrant inflammatory skin condition.

OBJECTIVES

To present the results of carbon dioxide (CO2) laser treatment of recalcitrant HS in nine patients who had failed to improve on medical and other surgical treatments.

METHODS

HS lesions consisting of abscesses, sinuses and granulation tissue were completely excised using the cutting mode of a CO2 laser, leaving only healthy residual subcutaneous fat. The wounds were closed by primary intention where possible and left to granulate otherwise. Outcomes were determined by clinical review and questionnaire.

RESULTS

Twenty-seven sites were treated in 19 sessions on nine patients. Seven procedures were performed under general anaesthesia and 12 under local. All patients rated their postoperative discomfort as less or equal to their preoperative state. Seven of the nine patients had complete remission for 12 months or longer after their last laser treatment and ceased all medications. High levels of patient satisfaction were reported with CO2 laser treatment. The main complication was axillary scar contracture in two patients but this was insufficient to limit limb movement.

CONCLUSIONS

CO2 laser treatment should be considered as a treatment option in recalcitrant HS, where multiple medical treatments have been ineffective.

Notes concerning the peritonitis of urinary aetiology

Urinary peritonitis (the uroperitoneum) is categorized as a difficult to diagnose clinical entity due to its poor manifestations. Vesical trauma following pelvis bone fracture is the most frequently involved in the uroperitoneum aetiology, followed by spontaneous vesical rupture and intraoperative iatrogenic lesions. One of the most important and constant signs that can occur is diffuse abdominal tension, without tenderness. The imagistic procedure that sets the diagnosis is retrograde cystography showing intraperitoneal urine effusion. Vesical rupture is a surgical emergency. The uroperitoneum is a particular type of peritonitis that has hidden and misleading symptoms which can delay the diagnosis long enough to endanger the patient's life.

Systemic ciclosporin and tacrolimus in dermatology

Ciclosporin and tacrolimus are calcineurin inhibiting immunosuppressant agents useful in the treatment of immune-mediated inflammatory dermatoses. Available data and clinical experience demonstrate ciclosporin's efficacy in treating psoriasis, atopic dermatitis, pyoderma gangrenosum, lichen planus, autoimmune bullous disease (in combination with corticosteroids), recalcitrant chronic idiopathic urticaria, and chronic dermatitis of the hands and feet. Although the role of topical tacrolimus in atopic dermatitis is well established, such experience with the oral formulation of tacrolimus has been limited. However, there are several case studies and anecdotal reports of the successful use of oral tacrolimus in various dermatoses. In this article we discuss the utility of systemic ciclosporin and tacrolimus in dermatology.
