OBJECTIVE: Clinical stage (cStage) in thyroid cancer determines extent of surgical therapy and completeness of resection. Pathologic stage (pStage) is an important determinant of outcome. The rate of discordance between clinical and pathologic stage in thyroid cancer is unknown. METHODS: The National Cancer Data Base (NCDB) was queried to identify 27,473 patients ≥45 years old with cStage I through IV differentiated thyroid cancer undergoing surgery from 2008-2012...

OBJECTIVE: Although loco-regional metastases occur in 5-10% of patients with papillary thyroid cancer (PTC), distant metastases are rare, especially to the pancreas. Here we review the literature regarding metastases to the pancreas from PTC and present an illustrative patient. METHODS: The literature search was performed through www.pubmed.org . The information regarding our illustrative case was obtained from the medical records of our institution. RESULTS: Since 1991, 11 cases of pancreas metastases of PTC have been reported...

F-18-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) is routinely performed in oncology patients for various indications including staging, restaging, recurrence detection, and treatment response evaluation. Many disease- and treatment-related complications can be incidentally detected on PET/CT, which may be due to the complication of radiotherapy, chemotherapy, intervention, or primary tumor itself. Some of these complications could be life threatening and need urgent intervention...

Purpose of Study: Loss of dopamine neurons in the brain is a characteristic feature of Parkinson's disease (PD). TRODAT-1 is a tropane derivative that binds to dopamine transporter (DAT) receptors. It can be used for noninvasive in vivo imaging of DAT receptors leading to the early detection of PD. The present study aims to optimize the in-house radiolabeling of TRODAT-1 with Tc-99 m in hospital radiopharmacy set up along with performing single-photon emission computed tomography/computed tomography imaging in patients with PD...

In the present study, the extracellular synthesis of Selenium nanoparticles (SeNPs) was carried out by using culture supernatant of Streptomyces griseoruber, an Actinomycetes member isolated from the soil. Bioreduction of SeNPs was confirmed by UV-Visible spectrophotometer that showed the peak at 575 nm. XRD pattern confirmed the non-crystalline or amorphous nature of the synthesised SeNPs. FTIR spectra revealed the possible functional group that is responsible for mediating the SeNPs formation. Size and distribution of the biosynthesised SeNPs were analysed by HR-TEM that showed the formation of particle size in the range of 100-250nm...

Background and objective: The prognosis of male anal squamous cell carcinoma (MASCC) and female anal squamous cell carcinoma (FASCC) is variable. The influence of tumor subtype on the survival rate and gender is poorly known. Our study is the largest population-based study and aims to outline the difference in survival between MASCC and FASCC patients. Methods: A retrospective population-based study was performed to compare the disease-specific mortalities (DSMs) between genders related to the tumor subtypes...

BACKGROUND: Patients with acromegaly have 2-3 times the expected mortality rates primarily due to cardiovascular risks. Echocardiographic studies showing improvement of cardiac function following transsphenoidal surgery (TSS) are limited. MATERIALS AND METHODS: All patients with acromegaly underwent preoperative echocardiography and tissue Doppler (Philips i33, 3D ECHO) for assessment of cardiac indices. In the prospective group of patients, echocardiography was repeated after 6 months of surgery...

The majority of RCCs occur within the 7th decade of life, uncommonly arising in adults ≤46years. We reviewed the clinicopathologic features of early-onset renal cell carcinoma (RCC) and evaluated the role of immunohistochemistry (IHC) in potentially identifying diagnoses of newly recognized RCC subtypes that may have been previously misclassified. A retrospective review was performed from 2011-2016 for cases of RCC. Early-onset RCC was defined as ≤46years of age. Clinicopathologic findings and hematoxylin and eosin (H&E) slides were reviewed on early-onset RCC patients...

Here, we have synthesized phenolic compounds (pc) based on conjugates from dextran aldehyde (dex-ald) and bovine serum albumin (BSA) and screening their potential activity as therapeutic agents in cancer disease. The synthesized conjugates were analyzed by UV-vis, FT-IR, XRD and SEM analysis. UV-vis spectra of conjugates showed the shifting of spectral peak at UV to visible region revealed the enhanced conjugation due to formation of linkage. The XRD peaks of conjugates found broader and indicating the amorphous phase of conjugating materials in compared to free components...

In this study, we have synthesized chitin-glucan quercetin conjugate (ChGCQ) by an easy and facile free radical grafting reaction. The structure of ChGCQ was confirmed by proton nuclear magnetic resonance ((1)H NMR) and Fourier transforms infrared spectroscopy (FT-IR). Curcumin was loaded into ChGCQ to study its anti-cancer efficiency. The biocompatibility of ChGCQ and curcumin loaded ChGCQ (Cu-ChGCQ) were analysed by different assays in Peripheral blood mononuclear cells (PBMCs) and cytotoxicity test was performed in a macrophage cancer cell line (J774)...

Somatostatin-14 is a native neuropeptide with widespread functions in the body. Self-assembly of somatostatin-14 into amyloid-like nanofibrils has been previously demonstrated in aqueous media. We here hypothesize that the somatostatin nanofibrils can form a stable depot that release monomers in a controlled manner. This study aims to investigate if somatostatin monomers are released from physical hydrogels formed in water and in the presence of electrolytes. The release kinetics of the somatostatin monomers is investigated for the first time...

Purpose: Radioactive iodine (RAI) treatment is often indicated after total thyroidectomy in differentiated thyroid cancer (DTC). However, its role in biochemical or loco-regional persistent DTC is unclear. We aimed to investigate the impact of a second RAI treatment in patients with incomplete response to initial treatment and no evidence of distant metastases. Methods: Patients who underwent at least two RAI treatments over a 20-year period at a tertiary hospital were identified...

OBJECTIVES: To evaluate the NeuroSAFE technique in a British setting in men undergoing RALP. PATIENTS AND METHODS: We retrospectively analysed our prospectively maintained database of patients who underwent RALP between Nov 2008 and Feb 2017. We examined preoperative pathological and functional parameters, intra-operative nerve sparing, post-operative histology as well as functional and oncological follow-up. We compared those who had a NeuroSAFE approach and those who had nerve sparing without NeuroSAFE...

The feeling of body-ownership can be experimentally manipulated using the rubber hand illusion (RHI) paradigm. Participants experience a sense of ownership over an artificial hand when their hidden real hand and the visible artificial hand are synchronously stroked. Using lesion masks and behavioral data from a previous study on RHI failure in acute stroke patients, we here employed lesion network-symptom-mapping (LNSM) based on normative functional connectome data to identify lesion-dependent network connectivity related to the experience of self-attribution of an artificial hand in the RHI paradigm...

Four decades ago, two staging systems were developed to help stratify CLL into different prognostic categories. These systems, the Rai and the Binet staging, depended entirely on abnormal exam findings and evidence of anemia and thrombocytopenia. Better understanding of biologic, genetic, and molecular characteristics of CLL have contributed to better appreciating its clinical heterogeneity. New prognostic models, the GCLLSG prognostic index and the CLL-IPI, emerged. They incorporate biologic and genetic information related to CLL and are capable of predicting survival outcomes and cases anticipated to need therapy earlier in the disease course...
