“A 43-year-old female with antiphospholipid syndrome and Graves’ disease developed a cutaneous leukocytoclastic vasculitis associated with antineutrophil cytoplasmic antibody (ANCA) against myeloperoxidase (MPO-ANCA) and proteinase-3 (PR3-ANCA), whilst treated with propylthiouracil (PTU). The skin lesions were progressively resolved after withdrawal of PTU and treatment with oral steroids. Selleck MK-4827 Patch

testing with PTU at 1%, 5%, and 10% in petrolatum was positive at 48 h. Despite positive ANCA titers after 1 year of follow-up, the patient maintains complete clinical remission. PTU is a common antithyroid drug, which has been known to induce ANCA-positive vasculitis. Although most U0126 nmr patients with this rare side effect have a good outcome, some fatal

cases have been reported. Therefore, patients treated with PTU should be carefully followed and monitored, not only for their thyroid state but also for early detection of potential serious complications of this drug. Early diagnosis and prompt cessation of PTU therapy are essential to improve the outcome. Also key aspects of PTU-induced ANCA-positive vasculitis are reviewed.”
“Object. Atlantoaxial tumors account for a substantial proportion of primary bone tumors in children. Before resection, surgeons must consider the complex regional anatomy, the potential for neurological compromise, craniocervical instability, and the question of tumor resectability in a growing spine. Using current technology, the authors analyzed surgical cases in this light and present outcomes and treatment recommendations after long-term patient follow-up.

Methods: The authors reviewed clinical records for Quizartinib ic50 23 children whose primary atlantoaxial bone tumors were treated from 1996 through 2010.

Results. Pathological lesions among the 23 patients were 4 aneurysmal

bone cysts, 2 osteochondromas, 5 chordomas, 4 osteoblastomas, 3 fibrous dysplasias, 4 eosinophilic granulomas, and 1 Ewing’s sarcoma. Clinical presentation consisted of neck pain (n = 23), headaches and occipital pain (n = 16), myelopathy (n = 8), and torticollis (n = 4). Selective angiography and coil embofization were undertaken for all patients with aneurysmal bone cysts and osteoblastomas, 2 patients with chordomas, 1 patient with fibrous dysplasia, and 1 patient with Ewing’s sarcoma. Primary embolization treatment of radiation-induced aneurysmal bone cyst of the atlas showed complete reossification. Results of CT-guided needle biopsy were diagnostic for 1 patient with eosinophilic granuloma and 1 with Ewing’s sarcoma. Needle biopsies performed before referral were associated with extreme blood loss for 1 patient and misdiagnosis for 2 patients. Surgery involved lateral extrapharyngeal, transoral, posterior, and posterolateral approaches with vertebral artery rerouting.
