A 49-year-old man presented with an acute onset of folliculitis on his right cheek. The folliculitis was unresponsive to antibiotics. A potassium hydroxide preparation of a scraping from the affected area revealed the presence of numerous Demodex mites. The patient was treated with topical crotamiton (Eurax) cream resulting in rapid resolution of the(More)
Neurofibromatosis type 2 (NF2) must be suspected in patients presenting with a unilateral vestibular schwannoma at a young age who are therefore at theoretical risk of developing bilateral disease. We identified 45 patients aged 30 years or less at the onset of symptoms of a unilateral vestibular schwannoma. Molecular genetic analysis of the NF2 gene was(More)
Multiple schwannomas have frequently been seen in patients with neurofibromatosis. Recently, the association of multiple cutaneous schwannomas, central nervous system tumors, and various neurologic deficits has been described in Japanese patients as a condition called schwannomatosis. We describe the first non-Japanese cases of schwannomatosis and compare(More)
Neurofibromatosis 2 (NF2), an autosomal dominant disorder that is characterised by tumours of cells of neural crest origin, is caused by inactivating mutations of the NF2 gene on chromosome 22q12. 2 Bilateral vestibular schwannomas are the most frequent manifestation of the disease, but other central and peripheral nervous system schwannomas, cerebral(More)
Oculo-dento-digital dysplasia (ODDD) is a rare autosomal dominant congenital disorder mainly affecting the development of the face, eyes, skeletal system, heart and dentition. ODDD has been mapped to chromosome 6q22-q24 and germline mutations have been identified in the connexin 43 gene, GJA1. Abnormalities of the skin, hair, and nails have been recognized(More)
Anti-Ro/SS-A antibody levels in 80 serum specimens from 12 patients with subacute cutaneous lupus erythematosus (SCLE) were determined by immunodiffusion and enzyme-linked immunosorbent assay in order to examine the changes in this autoantibody response with time and to study the relationship between levels of this antibody and SCLE skin disease activity.(More)
Infliximab is a chimeric immunoglobulin G1kappa monoclonal antibody against tumor necrosis factor alpha (TNF-alpha), a proinflammatory cytokine that participates in both normal immune function and the pathogenesis of many autoimmune disorders. Treatment with infliximab reduces the biologic activities of TNF-alpha and thus is indicated in the treatment of(More)
BACKGROUND Multiple surgical procedures are often a source of discomfort, pain, and disfigurement for patients with the nevoid basal cell carcinoma syndrome (NBCCS). OBJECTIVE The patient with NBCCS had approximately 45 identifiable basal cell carcinomas on her face. Multiple Mohs surgeries were performed to remove the largest tumors. A tumor-free plane(More)
