Graves' disease is an autoimmune thyroid disorder characterized by hyperthyroidism, and patients exhibit thyroid-stimulating hormone receptor antibody. The major methods of measuring circulating thyroid-stimulating hormone receptor antibody include the thyroid-stimulating hormone-binding inhibitory immunoglobulin assays. Although the diagnostic accuracy of these assays has been improved, a minority of patients with Graves' disease test negative even on second-generation and third-generation thyroid-stimulating hormone-binding inhibitory immunoglobulins. We report a rare case of a thyroid-stimulating hormone-binding inhibitory immunoglobulin-positive patient with Graves' disease who showed rapid lowering of thyroid-stimulating hormone-binding inhibitory immunoglobulin levels following administration of the anti-thyroid drug thiamazole, but still experienced Graves' hyperthyroidism. ⋯ The possible explanations for serial changes in the thyroid-stimulating hormone-binding inhibitory immunoglobulin results in our patient include the presence of thyroid-stimulating hormone receptor antibody, which is bioactive but less reactive on thyroid-stimulating hormone-binding inhibitory immunoglobulin assays, or the effect of reduced levels of circulating thyroid-stimulating hormone receptor antibody upon improvement of thyroid autoimmunity with thiamazole treatment. Physicians should keep in mind that patients with Graves' disease may show thyroid-stimulating hormone-binding inhibitory immunoglobulin assay results that do not reflect the severity of Graves' disease or indicate the outcome of the disease, and that active Graves' disease may persist even after negative results on thyroid-stimulating hormone-binding inhibitory immunoglobulin assays. Timely performance of thyroid function tests in combination with sensitive imaging tests, including thyroid ultrasound and scintigraphy, are necessary to evaluate the severity of Graves' disease and treatment efficacy.

Pin tract infection is a common complication of external fixation. It usually heals after treatment with debridement, antibiotics, and/or pin removal, only rarely developing into delayed osteomyelitis. We treated two patients with delayed methicillin-resistant Staphylococcus aureus-induced osteomyelitis of the tibia following pin tract infection. ⋯ Pin tract infection should not be considered a minor complication because osteomyelitis may develop, requiring treatment that is more aggressive than curettage of the pin tract. A gastrocnemius flap is a useful treatment option for refractory osteomyelitis because flap harvest causes less functional disturbance and is a relatively easy surgical technique.

Case Reports
Papillary fibroelastoma of the aortic valve presenting with chronic angina and acute stroke: a case report.
Papillary fibroelastomas are rare, benign cardiac tumors that are often found on cardiac valvular surfaces. Most are incidental discoveries during surgery or autopsy. The clinical presentation of fibroelastoma varies widely, ranging from clinically asymptomatic to severe thromboembolic events. ⋯ To the best of our knowledge, this is the first case report describing a patient with a cardiac papillary fibroelastoma who presented with both chronic angina and acute stroke.

Review Case Reports
Double localization of a non-anastomotic pseudoaneurysm after an axillofemoral bypass: a case report and review of the literature.
A traumatic non-anastomotic pseudoaneurysm is a rare complication of an axillofemoral bypass graft. Fewer than 20 cases have been reported in the literature. Our case is unusual in that we report a double localization of this complication. ⋯ Non-anastomotic pseudoaneurysm is a rarely described complication of a axillofemoral bypass graft. To the best of our knowledge, a double localization has not been described in the literature before. Minimally invasive techniques as a treatment option are being widely used as an alternative to open repair.

Although open injuries involving the brachial plexus are relatively uncommon, they can lead to permanent disability and even be life threatening if accompanied by vascular damage. We present a case report of a brachial plexus injury in which the urgency of the situation precluded the use of any ancillary diagnostic examinations and forced a rapid clinical assessment. ⋯ We believe that this case report illustrates the relevance of a sound anatomical knowledge of the brachial plexus in an emergency setting.
