Altered expression of aromatase and estrogen receptors in adipose tissue from men with obesity or type 2 diabetes.

Objective: Obesity and insulin resistance in men are linked to decreased testosterone and increased estradiol (E2) levels. Aromatase (ARO) converts testosterone into E2, and this occurs mainly in adipose tissue in men. E2 acts through estrogen receptors ESR1 and ESR2, and they potentially affect development of type 2 diabetes (T2D).

Fasciola Hepatica Mimicking Malignancy on 18F-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography.

A 48-year-old female with complaints of gastrointestinal symptoms such as abdominal pain, fatigue, vomiting, nausea, and weight loss was diagnosed with neuroendocrine tumor after removal of a 2 mm lesion from the stomach with endoscopic biopsy. Her magnetic resonance imaging that was performed due to on-going symptoms showed multiple linear hypointense lesions in the liver. Positron emission tomography/computed tomography (PET/CT) scan was performed for differential diagnosis, which showed high fluorodeoxyglucose (FDG) uptake in these lesions.

Temporary changes in neutrophil-to-lymphocyte, platelet-to-lymphocyte ratios, and mean platelet volume reflecting the inflammatory process after radioiodine therapy.

Objective: Data on the effects of radioiodine (RAI) therapy on systemic inflammation are very limited. The aim of this study is to explore alterations of subclinical systemic inflammatory markers, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV), after RAI therapy in patients with differentiated thyroid carcinoma (DTC).

Materials And Methods: We evaluated 57 DTC patients treated with RAI (RAI group), 37 DTC patients not treated with RAI (non-RAI control group), and 37 age-matched healthy individuals (healthy control group).

Liver metabolic activity changes over time with neoadjuvant therapy in locally advanced rectal cancer.

Objective: The aim of this study was to evaluate, using PET/computed tomography (CT), changes in liver metabolic activity in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (CRT).

Patients And Methods: A total of 29 biopsy-proven LARC patients between 2009 and 2012 were studied. Liver standardized uptake values (SUVs) and SUVs adjusted for lean body mass (SULs) were obtained from PET/CT images obtained at 1 h (early) and 2 h (late) after (18)F-fluorodeoxyglucose ((18)F-FDG) administration both before and after neoadjuvant CRT.

The correlation between the metabolic tumor volume and hematological parameters in patients with esophageal cancer.

Introduction: The aim of this study is to evaluate the correlation of the serum neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and mean platelet volume (MPV), with the standardized uptake value (SUVmax), and metabolic tumor volume (MTV) in F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patient with esophageal squamous cell cancer at baseline.

Methods: PET/CTs were performed in 52 patients with esophageal squamous cell cancer, making up the patient group. An additional 52 patients who underwent endoscopy due to dyspepsia with normal esophagus (as a control group) were included in the study to compare the hematological parameters between the patient groups.

Dyke-Davidoff-Masson Syndrome With Cerebral Hypometabolism and Unique Crossed Cerebellar Diaschisis in 18F-FDG PET/CT.

A 23-year-old man with Dyke-Davidoff-Masson syndrome (DDMS) was admitted to the hospital with increasing frequency of epileptic seizures. Physical examination revealed mental retardation, left facial asymmetry, and left-sided spastic hemiparesis. Dysdiadochokinesia on the left upper limb was detected, and there was no dysmetria.

The value of liver-based standardized uptake value and other quantitative 18F-FDG PET-CT parameters in neoadjuvant therapy response in patients with locally advanced rectal cancer: correlation with histopathology.

Aim: We aimed to investigate the value of PET-CT in therapy response and the correlation of quantitative PET parameters with histopathologic results in patients with locally advanced rectal cancer (LARC) before and after neoadjuvant chemoradiotherapy. We also analyzed the correlation of PET-CT parameters between Ki-67 and glucose transporter 1 (GLUT1).

Patients And Methods: A total of 29 patients diagnosed with LARC who had undergone a biopsy between 2009 and 2012 were included in our study.

Dual-phase F-18 FDG PET-CT in staging and lymphoscintigraphy for detection of sentinel lymph nodes in oral cavity cancers.

Aim: Our objective was to evaluate the diagnostic role of dual-phase fluor-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography-computed tomography (PET-CT) and planar lymphoscintigraphy in patients with oral cavity cancer (OCC). We also investigated the combined impact of F-18 FDG PET-CT and sentinel lymph node biopsy (SLNB) in decision making for patients with OCC.

Methods: Sixteen patients (4 female, 12 male; age range, 29-81 years) were included in this prospective study.

The diagnostic role of dual-phase (18)F-FDG PET/CT in the characterization of solitary pulmonary nodules.

Objective: Our objective was to evaluate the diagnostic role of dual-phase (18)F-fluorodeoxyglucose ((18)F-FDG) PET/computed tomography (CT) in the characterization of solitary pulmonary nodules (SPNs).

Patients And Methods: A total of 48 SPNs in 48 patients were included in this retrospective study. The final diagnosis was confirmed histopathologically or by follow-up CT.

The effect of radioiodine on the intima media thickness of the carotid artery.

Aim: The radiation can induce vessel injury. The result of this injury can be severe and life-threatening. There are a few studies demonstrating an increase in intima-media thickness (IMT) of the common carotid artery (CCA) after radiotherapy, especially in head and neck cancers.

Rest myocardial perfusion scintigraphy showing the invasion of the hydatid cyst in the myocardium.

A cardiac hydatid cyst is a rare complication of the Echinococcus infection, and it is seen in just 0.5% to 2% of all cases. Because it can cause sudden death, removing the cyst is recommended.

An evaluation of thyrotoxic autoimmune thyroiditis patients with triplex Doppler ultrasonography.

Objective: This study aimed to investigate the usefulness of blood flow parameters obtained from STA and CCA with Triplex Doppler ultrasonography (TDU) on patients with thyrotoxicosis.

Materials And Methods: This cross-sectional study included consecutive 24 patients with thyrotoxicosis and 18 healthy controls. The thyroid gland blood flow parameters were evaluated with TDU.

Is Imaging Time Between two Tc 99m DMSA Scans Sufficient for Reporting as Renal Parenchymal Scarring? Healed Parenchymal Renal Defect After 6 Years.

Unlabelled: We aimed to report a healed renal parenchymal defect after 6 years in a 9-year-old girl who was being followed for recurrent urinary tract infection (UTI). The first UTI was at the age of two. She was being followed with ultrasonography, urine analysis and urine culture since the first UTI.

The Effects of the Factors Related to the Patient and the Disease on the Performance of Ablation Therapy in Patients with Differentiated Thyroid Cancer who have Received I-131 Ablation Therapy.

Objective: To investigate whether the factors related to the patient and the disease have any effect on the success of ablation therapy in patients with differentiated thyroid cancer who have received I-131 ablation therapy.

Material And Methods: All the patients with differentiated thyroid cancer were referred for I-131 ablation therapy after thyroidectomy between July 2007 and September 2009. The patients had at least six months of follow-up.
