Twelve patients with solitary autonomous thyroid nodules were scanned with [99mTc] pertechnetate and by fluorescent imaging. Nodular dimensions were essentially identical on the two types of scans, but the relative scan densities in the nodular versus extranodular areas demonstrated striking differences. In 11 of the 12 patients, the ratio of nodular-to-extranodular radiotracer accumulation was...

Primary localized cutaneous nodular amyloidosis (nodular amyloidosis) is a rare and distinct type of amyloidosis, in which amyloid L deposition is limited to the skin and typically manifested as a tumefactive nodule on the acral sites. However, the definite cause of nodular amyloidosis is still unknown. Although it is relatively well known that the amyloid deposits in nodular amyloidosis origin...

background lower gastrointestinal bleeding (lgib) in children has many different etiologies and is a serious problem that warrants careful diagnostic work-up. materials and methods 164 colonoscopies were done during one year for determining the etiologies of lgib in children who was referred to children's medical center hospital. analyses of results were based on age, sex, etiology and clinical...

Nodular melanoma is the most aggressive subtype of melanoma, with rapid growth rate and metastatic potential. It is usually diagnosed at a locally advanced stage (Breslow thickness <2 mm) and is therefore associated with a poor prognosis. Nodular melanoma often does not fit the classic clinical ABCD criteria, but rather the EFG rule or 3 Cs criteria. Missing the diagnosis of nodular melanoma is...

Purpose. Secondary hyperparathyroidism with nodular hyperplasia is resistant to medical therapies. Cinacalcet is an effective treatment for severe secondary hyperparathyroidism. This multicentre retrospective study was designed to determine the long-term efficacy of cinacalcet in patients with nodular hyperplasia, the advanced type of parathyroid hyperplasia. Subjects and methods. The study sub...
