BACKGROUND & OBJECTIVE: Thyroid nodules are very common in our setup and their diagnosis on fine needle aspiration is not easy and is a taxing affair. It is a challenge to differentiate between follicular adenoma and follicular carcinoma without histology. Our objective was to investigate the role of Galectin-3 in fine needle aspirates of thyroid nodules as a prospective diagnostic marker and consequently its ability to differentiate benign from malignant neoplasms. METHODS: The research was conducted at the department of Pathology, King Edward Medical University, in association with other teaching institutions of Lahore from June 2012 to July 2014...

Specific coagulation factor inhibitors, most notably to coagulation factor VIII, can develop in patients with hemophilia after exposure to replacement factor or as an acquired (autoimmune) event. Such inhibitors can be detected by a combination of prolonged coagulation screening tests, such as the activated partial thromboplastin time, plus a non-correcting mixing test. Non-correction may only be evident, or else may be extenuated, with incubation at 37 °C. The Bethesda assay for quantitation of inhibitor strength is based on a combination of mixing tests followed by specific factor assays...

BACKGROUND: Niemann-Pick disease, type C1 (NPC1) is a lysosomal storage disorder characterised by progressive neurodegeneration. In preclinical testing, 2-hydroxypropyl-β-cyclodextrins (HPβCD) significantly delayed cerebellar Purkinje cell loss, slowed progression of neurological manifestations, and increased lifespan in mouse and cat models of NPC1. The aim of this study was to assess the safety and efficacy of lumbar intrathecal HPβCD. METHODS: In this open-label, dose-escalation phase 1-2a study, we gave monthly intrathecal HPβCD to participants with NPC1 with neurological manifestation at the National Institutes of Health (NIH), Bethesda, MD, USA...

Extracellular vesicles (EVs) are globular, membrane bound nanovesicles (30-100 nm range) that are shed both during normal cellular functioning and under pathological conditions by most cell types. In recent years, there has been significant interest in the study of these vesicles as conduits for the delivery of information between cells from both analogous and disparate tissues. Their ability to carry specialised cargo including signalling mediators, proteins, messenger RNA and miRNAs characterises these vesicles as primary facilitators of cell-to-cell communication and regulation...

BACKGROUND: The Bethesda assay (BA) for measurement of factor VIII (FVIII) inhibitors called for quantitation of positive inhibitors using dilutions producing 25-75% residual activity (RA), corresponding to 0.4-2.0 Bethesda units, recommending use of "more sensitive methods" for samples with RA closer to 100%. The Nijmegen modification (NBA) changed the reagents used but not these calculations. Some specimens negative by NBA have been shown to have FVIII antibodies detectable by sensitive immunologic methods...

Acquired haemophilia A (AHA) is a bleeding disorder that results from autoantibodies against factor VIII (FVIII). A 70-year-old man with a history of interstitial lung disease presented with spontaneous bleeding into his thigh. He had undetectable FVIII levels and a high-titre FVIII inhibitor (>2000ââ'¬â€°Bethesda units/mL) and was diagnosed with AHA. He had several relapses, required multiple haemostatic and immunosuppressive treatments but eventually achieved a stable remission after 2ââ'¬â€°years of therapy...

OBJECTIVES: The quality of cervicovaginal smears determines the success of cytology in screening programs for cervical cancer. Bethesda 2014 revisited the adequacy criteria for atrophic smears and redefined the squamous cell count in the "unsatisfactory" category. In this study, we evaluated the smear quality of Thinprep liquid-based cervicovaginal Papanicolaou cytology slides (TPS) that were previously deemed unsatisfactory, to determine reasons for such categorization. In addition, we attempted to establish the impact of the new adequacy criteria on the rate and management of unsatisfactory diagnosis...

BACKGROUND: Lynch Syndrome (LS) is the most common cause of inherited colorectal cancer (CRC). In British Columbia, most centres still use clinical criteria (Amsterdam II, Revised Bethesda, or the BC Cancer Agency's criteria) to determine who should undergo further first-line testing in the form of microsatellite instability or immunohistochemistry staining. Given the limitations with this strategy, LS is thought to be underrecognized. OBJECTIVE: To investigate whether LS is truly underrecognized when compared to the reported prevalence...
