Retrosternal goiter is an enlarged thyroid mass of which more than 50% is located in the mediastinum. Indications for surgery of retrosternal goiter include ineffective pharmacological treatment, mechanical syndrome, suspicion of malignancy and thyrotoxicosis. Computed tomography is the gold standard in the diagnosis of retrosternal goiter. The surgery can be performed from acervical incision, using sternotomy or thoracotomy.

The aim of our study was to evaluate our own group of retrosternal goiters. In 2011-2019, 1739 thyroid surgeries were performed at the 3rd Department of Surgery, University Hospital Motol, Prague. We retrospectively followed the age, gender, retrosternal spreading, postoperative complications (especially hypocalcemia, bleeding and dysphonia) and the definitive histological finding.

Retrosternal goiters were presented in 202 (19.2%) of the total of 1739 thyroid surgery patients. Sternotomy was performed in 31 patients. Women (61%) predominated over men (39%). The mean operating timeality, higher blood loss and longer hospital stay; nevertheless, it does not increase the risk of long-term postoperative complications. Procedures requiring sternotomy or thoracotomy should be done at centers experienced in these types of procedures.
Papillary thyroid cancer (PTC), especially micropapillary variant (MPTC), is the most common thyroid malignancy. Biological behavior is not aggressive and the patientsprognosis is satisfactory. The objective of our comparative retrospective study was to evaluate whether the incidence is rising in the Region of Zlín and if less extensive approach was adopted by Czech endocrinologists.

We compared 2 groups from years 2005-2008 and 2014-2018. The incidence of thyroid cancer, the PTC and the MPTC, the extent of the surgery and the lymphadenectomy, number of removed lymph nodes and the number of positive lymph nodes were observed.

We gathered 1353 patients in group 1. We found 220 malignancies (16.3%), 180 (81.8%) were PTC with MPTC variant in 44.4% (80 patients). All patients underwent atotal thyroidectomy. We made 18 central and 10 lateral lymphadenectomies, 280 lymph nodes were collected with meta-stasis in 29,3%. In group 2 with 1569 patients we found 318 (20.3%) carcinomas, PTC in 302 (94.6%) cases. The MPTC accounted for 215 (67.4%) cases. 10 patients with MPTC underwent hemithyroidectomy only. Numbers of central and lateral lymphadenectomies rose to 52 and 24 respectively. We gathered 376 lymph nodes with proven metastasis in 44.4% of these nodes.

Both, the incidence and the frequency of PTC and MPTC are rising in our region. However, the number of less invasive procedures is not increasing significantly despite representing asufficient way of treatment. We need wider adoption of these evidence-based recommendations by indicating endocrinologists in the Czech Republic.

Thyroid tumors are heterogeneous in origin, morphology, biological behavior and therapeutic options. Substantial advances in diagnostic methods for thyroid cancer have led to detection of earlier stages of the disease that have the possibility of targeted therapeutic treatment and improved patient prognosis. In addition to surgical treatment, hormonal suppression and radioiodine therapy, targeted molecular therapy, which requires genetic testing, has come to the fore in recent decades. In the summary, we present an overview of current knowledge on the genetic background of individual types of thyroid carcinomas and the possibilities of therapeuticintervention.The authors present an outline of the development of thyroid surgery from the ancient times to the beginning of the 20th century, when the defini-tive surgical technique have been developed and the physiologic and pathopfysiologic consequences of thyroid resections have been described. The key representatives, as well as the contribution of the most influential czech surgeons are mentioned.MAIT cells are a separate cell population differentiating in the thymus. They are mostly present in the peripheral blood, liver, intestine, and lungs, less often in other tissues, and infrequently in the lymph nodes. The presentation molecules for MAIT cells are MR1 proteins. They are evolutionarily conserved and non-polymorphic, resemble class I HLA molecules, and are expressed by all cell types. They present bacterial and yeast vitamin metabolites which arise during the synthesis of vitamin B2. The effector functions of MAIT cells are promoted through cytokine synthesis. They also act cytotoxically, directly killing infected or tumour cells. MAIT cells may also play a role in pathological processes. Their involvement in the development of rheumatoid arthritis, systemic lupus erythematosus, autoimmune diabetes mellitus, Crohn's disease, and bronchial asthma has been demonstrated. In practical terms, MAIT cells are very sensitive to therapeutic doses of glucocorticoids. Treatment of patients with BA or chronic obstructive pulmonary disease with glucocorticoids increases their susceptibility to pneumonia, especially when caused by Streptococcus pneumoniae.Despite health literacy being an important assumption for maintaining a healthy population, there are not many studies focusing on health literacy concerning HIV infection among adolescents in the Czech Republic and among Czech authors. ASP2215 manufacturer In contrast, there are plenty of scientific papers and researches focused on awareness and susceptibility of adolescents in most affected regions of the world, Sub-Saharan Africa and India particularly. Adolescents belong to a high-risk group of the population. Education is one of the most important factors that influence the level of risk of HIV infection. However, increasing health literacy is only implemented in some types of secondary schools in the Czech Republic. The goal of this study is to verify health literacy concerning HIV infection among adolescents in two types of Czech secondary schools (grammar school and vocational school) in two Czech regional cities (Plzeň and České Budějovice). To determine the level of health literacy of HIV infection, a questionnaire (13 open and 9 closed questions) was compiled.
