Vulval involvement in Crohn’s disease (CD) is rare, particularly in children. The clinical features include erythema, edema, ulceration, and labial skin tags. The authors present two cases of children with vulval CD. In both cases, marked labial edema was the presenting feature. In one patient the immunomodulator tacrolimus ointment 0.03% was used with success. In the second patient control was achieved with intralesional triamcinolone in combination with systemic metronidazole.

A 75-year-old man with ulcerative colitis (UC) and diet controlled diabetes mellitus presented with a 3-week history of slightly itchy, red plaques on both lower limbs ascending gradually to cover the trunk and arms. One week later, he developed a flare up of his UC. Routine blood tests showed modest drop in haemoglobin (122 g/L) and C reactive protein (85 mg/L). Serology was remarkable for high antiproteinase 3 (c-ANCA). Serum electrophoresis showed a mildly positive paraprotein band (γ region). Stool culture was negative. Urine analysis showed proteinuria. Skin biopsy showed features of urticarial vasculitis (UV). He underwent a flexible sigmoidoscopy after the flare up showed mildly active UC. The patient was given hydrocortisone for 7 days and then prednisolone. Both rash and UC subsided. Electrophoresis was repeated 4 weeks later showing normal pattern. Prednisolone has been gradually reduced. Although rare, UV can be considered as one of the skin manifestations of UC.

Introduction Inflammatory bowel disease has been associated with a number of cutaneous and systemic neutrophilic disorders, including pyoderma gangrenosum. In 1972, the term chronic multi-focal recurrent osteomyelitis was given to a sterile neutrophilic condition which has been associated with inflammatory bowel disease. Case Report We report a case of a 23-year-old man with long-standing severe Crohn’s disease which necessitated subtotal colectomy. He subsequently developed progressive, intermittent back pain that were limiting his functional movement. Numerous investigations to identify what initially was thought to be an infectious process failed to lead to the diagnosis. Biopsy of the spine identified a sterile neutrophilic infiltrate and the diagnosis of chronic recurrent multi-focal osteomyelitis was made which was successfully treated with immunosuppressive drugs. Conclusion Inflammatory bowel disease can present with cutaneous and systemic neutrophilic disorders and this association is becoming increasingly recognized by gastroenterologists and dermatologists. Chronic recurrent multi-focal osteomyelitis is a sterile neutrophilic disorder which can present with bone pain and responds to immunosuppressive therapy.

Ciclosporin is widely used in a number of inflammatory disorders and has the potential for drug interactions. We report here a case of acute kidney injury due to the interaction of ciclosporin with methyl-1-testosterone. This has not been previously reported and it is relevant as methyl-1-testosterone can be purchased online. Physicians should be aware of any over the counter or online purchased “supplements” and consider possible drug interactions.

Background Stomal leaks can be associated with significant social, psychological and physical morbidity for ostomy patients. Poor fitting of the stoma appliance due to irregularities of skin contours is one cause of stoma leaks which commonly result in secondary irritant dermatitis prompting presentation to a dermatologist. In addition to skin-directed topical therapy and review of stoma appliances, correction of contour defects with intradermal injections of filler materials is one possible treatment to improve adhesion and reduce leaks. Cases We report eight cases of ostomy patients, who presented with stoma leaks and associated dermatitis, who were treated with intradermal injections of the porcine collagen (Permacol™) or subcutaneous injections of polyacrylamide hydrogel (Aquamid Reconstruction™) for correction of skin contour defects. Resolution or improvement of symptoms was achieved for five patients, and no complications were noted as a result of treatment. Conclusions This report represents the largest series of ostomy patients treated for correction of peristomal skin contour defects with injection therapy. Treatment was well tolerated and performed in the outpatient setting under local anesthetic. Attempted correction of peristomal skin contour defects using injection of filler materials represents a potential alternative to surgical intervention and can result in significant benefits for the patient.

The identification of robust endotypes—disease subgroups of clinical relevance—is fundamental to stratified medicine. We hypothesized that HLA-C∗06:02 status, the major genetic determinant of psoriasis, defines a psoriasis endotype of clinical relevance. Using two United Kingdom–based cross-sectional datasets—an observational severe-psoriasis study (Biomarkers of Systemic Treatment Outcomes in Psoriasis; n = 3,767) and a large population-based bioresource (UK Biobank, including n = 5,519 individuals with psoriasis)—we compared demographic, environmental, and clinical variables of interest in HLA-C∗06:02–positive (one or two copies of the HLA-C∗06:02 allele) with those in HLA-C∗06:02‒negative (no copies) individuals of European ancestry. We used multivariable regression analyses to account for mediation effects established a priori. We confirm previous observations that HLA-C∗06:02–positive status is associated with earlier age of psoriasis onset and extend findings to reveal an association with disease expressivity in females (Biomarkers of Systemic Treatment Outcomes in Psoriasis: P = 2.7 × 10 –14, UK Biobank: P = 1.0 × 10 –8). We also show HLA-C∗06:02–negative status to be associated with characteristic clinical features (large plaque disease, OR for HLA-C∗06:02 = 0.73, P = 7.4 × 10 –4; nail involvement, OR = 0.70, P = 2.4 × 10 –6); higher central adiposity (Biomarkers of Systemic Treatment Outcomes in Psoriasis: waist circumference difference of 2.0 cm, P = 8.4 × 10 –4; UK Biobank: waist circumference difference of 1.4 cm, P = 1.5 × 10 –4), especially in women; and a higher prevalence of other cardiometabolic comorbidities. These findings extend the clinical phenotype delineated by HLA-C∗06:02 and highlight its potential as an important biomarker to consider in future multimarker stratified medicine approaches.
