Thyroid-stimulating hormone (TSH) is a growth factor associated with the initiation and progression of well-differentiated thyroid cancer (WDTC). Atypia of undetermined significance and follicular lesion of undetermined significance (AUS/FLUS) are the most uncertain cytological diagnoses of thyroid nodules. The aim of the study was to determine the association of histopathological diagnosis with preoperative serum TSH levels in patients with AUS/FLUS thyroid nodule diagnosis.

Atypia and follicular lesions of undetermined significance (AUS/FLUS) is the most controversial category of The Bethesda System. The risk of malignancy (ROM) in this group is estimated as 5-15%, however, the occurrence of two or more subsequent biopsy results with AUS/FLUS diagnosis makes these clinical situations more complex. We evaluated the ROM and prognostic value of aggressive ultrasound (US) features in 342 patients with thyroid nodules (TNs) with subsequent biopsy results of AUS/FLUS.

Purpose: Although some prognostic variables and risk factors for thyroid cancer (TC) are age-related, the association between age and the risk of TC in patients with thyroid nodules (TNs) assigned to atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS) is poorly estimated. The aim of this study was to assess the histopathology of AUS/FLUS and the risk of TC according to the age of the patients at the time of AUS/FLUS diagnosis.

Patients And Methods: Among 5021 individuals treated for TNs at one institution from 2008 to 2018, 161 (3.

Epidemiological studies have shown a strong association between high body mass index (BMI) and papillary thyroid cancer (PTC). We assessed the clinical and histopathological features of PTC in patients with a higher BMI and compared them to analogous parameters in PTC patients with a normal BMI. We retrospectively analyzed 5021 medical records of patients admitted and surgically treated for thyroid tumors in one center between 2008 and 2018.

Background: Currently, less aggressive treatment or even active surveillance of papillary thyroid microcarcinoma (PTMC) is widely accepted and recommended as a therapeutic management option. However, there are some concerns about these approaches. We investigated whether there are any demographic, clinical and ultrasound characteristics of PTMC patients that are easy to obtain and clinically available before surgery to help clinicians make proper therapeutic decisions.

Background: The relationship of diffusely adherent Escherichia coli (DAEC) with pediatric inflammatory bowel disease (IBD) has not been previously studied. Diffusely adherent E. coli are a common cause of long-lasting childhood diarrhea and we postulated that they may induce inflammation of the intestinal mucosa, contributing to the development of IBD in susceptible children.

Introduction: Cytokeratin-19 (CK19) is recognized as a reliable tumor marker of papillary thyroid carcinoma (PTC). The general prognosis in the classical subtype of PTC (CSTPTC) remains favorable, but some cases can be very aggressive. The aim of this study was to evaluate the localization and intensity of immunohistochemical CK19 expression in CSTPTC and its associations with the clinical and pathological characteristics of patients with CSTPTC in the Silesian region.

Background: Epidemiological studies suggest that long-term administration of proton pump inhibitors (PPIs) may decrease bone mineral density (BMD) and increase the risk of osteoporotic fractures. The aim of the study was to assess the influence of pantoprazole on bone metabolism in growing rats.

Methods: The experiment was carried out on twenty-four young male Wistar rats divided into two groups receiving either pantoprazole at the dose of 3mg/kg or vehicle for 12 weeks.

One-step nucleic acid amplification (OSNA) detects and quantifies, with the use of a polymerase chain reaction, the presence of cytokeratin 19 mRNA in sentinel lymph nodes. The main advantage of the OSNA assay is the avoidance of second surgery in case of positive sentinel lymph node diagnosis. The objective of this study was to evaluate the significance of matrix metalloproteinase 9 expression by immunohistochemistry as supporting marker to cytokeratin 19 mRNA in sentinel lymph nodes in breast cancer patients and to relate this expression with clinicopathological data.

Background: Ideal pouch created during restorative proctocolectomy is a new gastrointestinal organ--"neorectum". Although it is made from the ileum, it takes over function of the removed rectum. This new function results in significant morphological changes in pouch's mucous membrane, which becomes similar to the large bowel mucosa.

A few case reports have only been published to date, which show the possible link between mastocytosis and gastroesophageal reflux disease (GERD). Here, we present a 17-month-old boy with urticaria pigmentosa who also suffered from GERD. First skin lesions accompanied by gastrointestinal symptoms (regurgitations, appetite worsening) were noticed at the age of four months.

Thyroid carcinomas are the most frequently occurring tumours in the endocrine system. Metallothioneins (MT) and Ki-67 proteins are present in intensely proliferating cells, and their expression has been observed in numerous tumours, including thyroid tumours. The purpose of this study was to analyse the relationship between intensity of MT expression and Ki-67 antigen on one hand and histological features of the examined thyroid tumours on the other.

Testicular cancer is broadly divided into seminoma and non-seminoma types for treatment planning because seminomas are more sensitive to radiation therapy. Non-seminomatous germ-cell testis tumors represent a majority of all testicular neoplasms and include yolk sac tumor, embryonal carcinoma, choriocarcinoma, teratoma and undifferentiated tumors. Malignant neoplasms account for approximately 25% of neoplasms of the paratesticular tissues and most of them are sarcomas.
