Most personal care products for babies and children contain 1 or more sensitizers. Products containing more sensitizers tend to cost less than those without any sensitizing ingredients.

There are few reported cases of cutaneous intestinal metaplasia or primary adenocarcinoma arising at the ileostomy site following panproctocolectomy. These complications have been seen almost exclusively in patients with familial adenomatous polyposis and inflammatory bowel disease (IBD). However, benign intraepidermal colonic mucosa at a reversed ileostomy site in a patient without familial adenomatous polyposis or IBD has not been documented. We report a case of a 51-year-old female with a history of colonic adenocarcinoma who presented with pruritic, erythematous, scaly plaques on the right lower abdomen, present since reversal of her ileostomy in 2007. Skin biopsy revealed benign foci of colonic epithelium with no evidence of adenomatous change. Benign intraepidermal colonic mucosa was diagnosed based on histopathologic findings and immunohistochemistry. To our knowledge, this is the first case of intraepidermal benign colonic metaplasia forming in a patient following ostomy reversal. The case emphasizes the importance of patient education and physical examination of the stoma or stoma remnants for detection of unusual or changing lesions due to the risk for malignant transformation. It also demonstrates that benign colonic mucosa should be considered in the differential diagnosis when evaluating lesions near ileostomy sites, regardless of whether the patient has a history of familial adenomatous polyposis or IBD.

Terbinafine is often considered contraindicated in those with liver disease, as one of the known side effects is hepatotoxicity. We report the first case documenting the safe use of oral terbinafine in a 77-year-old woman with stable autoimmune hepatitis presenting with extensive tinea corporis. Precautions were carried out to minimise the risk of worsening hepatotoxicity, including consultation with the patient’s hepatologist, limiting terbinafine exposure to less than 6 weeks, monitoring of liver function tests, and patient education. The patient’s fungal infection cleared without any signs or symptoms of worsening liver disease. The rash had not recurred 6 months after treatment. When terbinafine must be used in a patient with pre-existing liver disease, we recommend considering a short course of oral terbinafine after consultation with their hepatologist, obtaining baseline liver function tests with consideration of further monitoring during treatment course, and patient education on the signs and symptoms of liver injury.

Background This window of opportunity trial evaluated the safety of intratumoral Copaxone® and profiled immune markers in biopsies before and after treatment. Methods Patients with percutaneously accessible malignancies scheduled for surgical resection with curative intent were eligible to participate. Adverse events from one, two, or three injections of Copaxone® were monitored leading up to surgical resection. Using RNA sequencing and spatial protein profiling of immune-related targets, changes in mRNA and protein expression patterns, respectively were assessed in tumor biopsy samples pre- and post-treatment. Results Adverse events at the injection site were mild and consistent with historic subcutaneous administration of Copaxone®. Increased intratumoral immune activity was evident in most patients, including the upregulation of genes associated with immune stimulation and targets of checkpoint inhibitor therapy. Conclusions Intratumoral injection of Copaxone® was well tolerated, and immune profile changes in the tumor microenvironment warrant its further evaluation as human intratumoral immunotherapy.
