BACKGROUND: Serum protein electrophoresis (SPE) and immunofixation electrophoresis (IFE) are used in the diagnosis and monitoring of plasma cell dyscrasias. IFE is considered the most sensitive method for the detection of monoclonal proteins (M-proteins), but it is not quantitative. The goal of this study was to establish the analytical sensitivity and diagnostic performance of SPE on the Sebia Hydrasys using HYDRAGEL 30 PROTEIN(E) β1-β2. METHODOLOGY: Patient sera with a previously identified M-protein (IgG, IgA or IgM) were serially diluted with a normal serum pool and electrophoresed on the Sebia Hydrasys using HYDRAGEL 30 PROTEIN(E) β1-β2...

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignancy, with an annual incidence of 1 or 2 cases per million. Biochemical diagnosis is challenging because up to two-thirds of the carcinomas are biochemically silent, resulting from de facto enzyme deficiencies in steroid hormone biosynthesis. Urine steroid profiling by GC-MS is an effective diagnostic test for ACC because of its capacity to detect and quantify the increased metabolites of steroid pathway synthetic intermediates...

BACKGROUND & AIMS: Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) is prevalent worldwide. Despite its limitations, serum alpha-fetoprotein (AFP) remains the most widely-used biomarker for the diagnosis of HCC. This study aimed to assess whether measurement of peripheral plasma Dickkopf-1 (DKK1) and Tie2-expressing monocytes (TEMs) could overcome the limitations of AFP and improve the diagnostic accuracy of HCC. METHODS: Plasma DKK1 level and the percentage of TEMs in peripheral CD14+CD16+ monocytes from HCC patients (n = 82), HBV-related liver cirrhosis (LC) patients (n = 29), chronic hepatitis B (CHB) infected patients (n = 28) and healthy volunteers (n = 31) were analyzed by ELISA and flow cytometry...

BACKGROUND: Bilateral tubal ectopic pregnancies are a rare subset of ectopic pregnancy that can pose a diagnostic dilemma for clinicians. There is no distinct clinical presentation for bilateral tubal ectopic pregnancies, although they are typically associated with assistive reproductive techniques. In addition, there is no single diagnostic feature to help clinicians delineate bilateral tubal ectopic pregnancies from other types of ectopic pregnancy prior to passing the discriminatory zone (such as heterotopic pregnancy or twin ectopic [two gestational sacs in one tube])...

INTRODUCTION: Thyrotoxicosis is a common disease encountered in Endocrine Outpatient Department (OPD). Two common causes of thyrotoxicosis are Destruction Induced Thyrotoxicosis (DIT) and Graves' Disease (GD). Differentiating DIT and GD based on clinical findings, is often not possible due to nonspecific symptoms. Thyroid scan is considered most reliable method for differentiating DIT and GD. AIM: To differentiate DIT and GD using the ratio of free triiodothyronine (fT3) and free thyroxine (fT4) thus avoiding thyroid technetium scan which is expensive and not accessible in developing countries like Nepal...

Delayed diagnosis in invasive aspergillosis (IA) contributes to its high mortality. Gliotoxin (GT) and bis-methyl-gliotoxin (bmGT) are secondary metabolites produced by Aspergillus during invasive, hyphal growth and may prove diagnostically useful. Because IA pathophysiology and GT's role in virulence vary depending on the underlying host immune status, we hypothesized that GT and bmGT production in vivo may differ in three mouse models of IA that mimic human disease. We defined temporal kinetics of GT and bmGT in serum, bronchoalveolar lavage fluid (BALF) and lungs of A...

Spotted fever is a rare acute and multisystemic febrile infectious disease with a mortality rate of ≥50% without adequate antibiotic treatment, and in diagnosed and treated cases, of approximately 2.5%. Currently, the applied test to diagnose this disease is the indirect immunofluorescence reaction, however two samples of paired sera are necessary to confirm the diagnosis, since using only one sample may allow for confusion with cross reactions. OmpA is an outer membrane protein present in the R. rickettsia, the etiological agent of spotted fever, able to activate dendritic and macrophage cells...

Many cytological studies on medullary thyroid carcinoma (MTC) have been reported; however, such studies in large series of patients with MTC have not been performed. We investigated MTC at a single institution in Japan using fine-needle aspiration cytology (FNAC), and aimed to establish a preoperative diagnostic algorithm for MTC. FNAC was performed in 119 of 149 patients with nodules (79.9%) who ultimately underwent surgical resection. Moreover, hereditary MTC was diagnosed preoperatively in 22 nodules that did not undergo FNAC (39...
