A 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. In the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. However, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...

Purpose: To evaluate the diagnostic accuracy of 131I-6β-iodomethyl-19-norcholesterol (NP-59) adrenal scintigraphy for subtyping diagnosis primary aldosteronism (PA), considering as gold standard unilateral PA (UPA), either results venous sampling (AVS) or outcome after adrenalectomy. Methods: A retrospective multicenter study was performed on patients from 14 Spanish tertiary hospitals who unde...

Purpose: To compare the effects of gallium-67 (Ga-67) scintigraphy with computerized tomography (CT) scanning in the diagnosis of head and neck neoplasm. Materials and Methods: Eighty-three patients with neoplasm in head and neck underwent local CT scanning and Ga-67 scintigraphy preoperatively. The results were verified pathologically after operation. Results: In total 43 cases of benign neopl...

UNLABELLED Somatostatin receptor scintigraphy (SRS) has been shown to reveal sarcoidosis sites. The aim of this study was to prospectively compare SRS and gallium scintigraphy in the evaluation of pulmonary and extrapulmonary involvement in patients with proven sarcoidosis. METHODS Eighteen patients with biopsy-proven sarcoidosis were included. Nine were or recently had been receiving steroid...

BACKGROUND Quantitative evaluation of pulmonary perfusion using lung perfusion scintigraphy in patients with atriopulmonary anastomosis (APA) or total cavopulmonary connection (TCPC) or partial cavopulmonary connection (PCPC) is difficult because of preferential draining of the venae cavae to one lung. Scintigraphy is the gold standard. Phase-velocity MRI (PV-MRI) is a new technique for determi...

BACKGROUND Current breath tests for measurement of gastric emptying of solids are expensive, possibly inaccurate, and require cumbersome calculations. AIMS We wished to validate a simplified solid gastric emptying test using a [(13)C]Spirulina platensis breath test for accurate results relative to scintigraphy. SUBJECTS Thirty healthy volunteers. METHODS We measured gastric emptying of eg...

Background: The study of antiphospholipid antibodies (aPL), not included in the Sydney diagnostic criteria, syndrome (APS) and systemic lupus erythematosus (SLE) is poorly understood. Objectives: To determine frequency detection IgA-aCL IgA-aβ2GP1 IgG to β2GP1 domain 1 (IgG-aβ2GP1-D1) patients with APS without SLE. Methods: ELISA chemiluminescence assays (CMA) were used test 63 sera patients: 2...

IgG deficiency can predispose to recurrent pyogenic infections. The association of IgG deficiency with Clostridium difficile infection has been infrequently reported in the literature. We present a case of a middle-age woman with multiple hospitalizations for recurrent C. difficile in a short span of time which prompted consideration of a possible fecal transplant. On evaluation, she was found ...

The objective of this study was to determine the effects of supplemented selenium (Se) on plasma cortisol, red blood cell glutathione peroxidase activity (RBC GSH-PX-1), concentration of immunoglobulin G (IgG) and body weight in pneumonic suckling calves. Ten Holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...
