Purpose: Interstitial fibrosis in papillary thyroid microcarcinoma is a subject which is under-investigated. The aim of this study is to determine the relationship between interstitial fibrosis, the subtypes of papillary microcarcinoma, and the established prognostic factors.
Material And Methods: A total of 75 patients diagnosed with papillary microcarcinoma of the thyroid from January 2011 to December 2020 have been evaluated retrospectively, using demographic features, tumor size, subtype of the tumor, surgical margin status, unifocality, lymphovascular invasion, extracapsular spread and lymph node metastasis as parameters.
Background: Prophylactic central lymph node dissection (CLND) in papillary thyroid carcinoma (PTC) is still controversial. This study aimed to analyze the factors related to the patient and tumor characteristics affecting central lymph node metastasis (CLNM) in PTC patients and to evaluate the contribution of the results to shaping the surgical treatment algorithm.
Methods: Two hundred and fifty-five PTC patients who underwent total thyroidectomy and CLND were evaluated retrospectively.
Background: The aim of this study was to evaluate the degradation of tryptophan (Trp), neopterin production and antioxidant capacity in patients with benign and malignant thyroid disease.
Methods: For this reason, the levels of tryptophan, kynurenine (Kyn) and neopterin, and superoxide dismutase (SOD) and catalase (CAT) enzyme activities in 67 thyroid patients were evaluated in our study and the results were compared with 30 healthy controls.
Results: Tryptophan and kynurenine levels in thyroid patients decreased compared to the control group.

High-resolution ultrasonography and the ability to perform fine-needle aspiration biopsy even for nodules smaller than three millimeters have considerably increased the detection rate of thyroid micropapillary carcinoma (TMPC). Despite favorable prognosis, the prevalence of cervical lymph node metastases in patients with TMPC is approximately 30%.

Context: Thyroid incidentaloma is a common disorder in endocrinology practice. Current literature regarding the risk of thyroid cancer in incidentalomas found in patients with non-thyroid cancer is limited.
Objective: The aim of the present study was to investigate the frequency of thyroid malignancy in thyroid incidentalomas detected in patients with non-thyroid cancer.
Introduction: The aim of this study was to compare the diagnostic adequacy of thyroid samples obtained by aspiration or capillary biopsy techniques, with 22 or 27 gauge needles, and with or without on-site cytological analysis (OCA).
Material And Methods: Four hundred patients with thyroid nodules underwent ultrasound (US)-guided fine-needle biopsies. Patients were divided into eight groups according to needle size (22 vs.
Aim: To evaluate the efficiency of ultrasound elastography (USE) in the differential diagnosis of thyroid nodules.
Methods: One hundred thyroid nodules in 100 patients (79 females, 21 males, age range 18-78; mean age = 45.6 years) were evaluated with real-time freehand USE, using Hitachi EUB 7500 equipment and elasticity scores were obtained.
The objective of this study was to enhance the solubility, dissolution rate, and oral bioavailability of a very poorly water-soluble anti-fungal agent, ketoconazole (KET), by inclusion complexation with a highly-soluble cyclodextrin derivative, hydroxypropyl-beta cyclodextrin (HP-beta-CD). Two groups of tablets containing KET alone and KET:HP-beta-CD (1:2) kneaded product (KP) including magnesium stearate and lactopress (anhydrous and spray-dried) as excipients were prepared by direct compression method. After the characterization studies, the in vitro dissolution studies of these tablets in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) were carried out.

Some biochemical agents as well as increased levels of intracellular calcium also play important roles in preservation injury during cold storage. In the current study, we aimed to test if the addition of a calcium channel blocker, sodium nitroprusside, or glutathione into preservation solution would reduce upregulation of adhesion molecules, thus leading to decreased preservation injury in the rat liver.

Methods: Thirty-six patients with parathyroid adenomas were studied prospectively. All patients were evaluated with both MIBI and (MIBI + Tc-99m) study.
Breast ductoscope is a fiberoptic endoscope used for examining the distal breast ducts under direct vision in order to identify the source of pathologic nipple discharge. The purpose of this study was to investigate the reliability of intra-operative breast ductoscopy in patients with pathologic nipple discharge, which could not be identified by radiologic tests. Between April 2002 and March 2007, breast ductoscopy was performed in 34 patients who had pathologic nipple discharge with no radiologic evidence about the source.

Methods: Between January 2001 and March 2006, 982 patients underwent thyroidectomy in single institute. A retrospective analysis was performed on demographic characteristics and pathology reports of patients, complications of surgery as well as the follow-up of patients.
Purpose: Intestinal anastomotic healing is a complex procedure in which several mediators and cytokines play roles. Calcitonin gene-related peptide is an important neuropeptide in inflammation. In this study we aimed to investigate the effect of calcitonin gene-related peptide on healing of intestinal anastomosis in rats with obstructive jaundice.
