OBJECTIVES: One day session LINAC based stereotactic radiosurgery (SRS) at LINAC accelerator is a method of "conservative" attitude to treat the intraocular malignant uveal melanoma. METHODS: We used model Clinac 600 C/D Varian (system Aria, planning system Corvus version 6.2 verification IMRT OmniPro) with 6 MeV X by rigid immobilization of the eye to the Leibinger frame. The stereotactic treatment planning after fusion of CT and MRI was optimized according to the critical structures (lens, optic nerve, also lens and optic nerve at the contralateral side, chiasm). The first plan was compared and the best plan was applied for therapy at C LINAC accelerator. The planned therapeutic dose was 35.0 Gy by 99 % of DVH (dose volume histogram). RESULTS: In our clinical study in the group of 125 patients with posterior uveal melanoma treated with SRS, in 2 patients (1.6 %) was repeated SRS indicated. Patient age of the whole group ranged from 25 to 81 years with a median of 54 TD was 35.0 Gy. In 2 patients after 5 year interval after stereotactic radiosurgery for uveal melanoma stage T1, the tumor volume increased to 50 % of the primary tumor volume and repeated SRS was necessary. CONCLUSION: To find out the changes in melanoma characteristics after SRS in long term interval after irradiation is necessary to follow up the patient by an ophthalmologist regularly. One step LINAC based stereotactic radiosurgery with a single dose 35.0 Gy is one of treatment options to treat T1 to T3 stage posterior uveal melanoma and to preserve the eye globe. In some cases it is possible to repeat the SRS after more than 5 year interval.

Prostate cancer is a serious oncological disease in males. There has been a significant escalation in the incidence of this malignancy in the Czech Republic and in developed countries of Europe recently. Conversely, in countries with an altered health system, a minor increase in new cases of this disease is recorded. The causes of the high incidence of prostate cancer in developed countries appear to be the introduction of the prostate specific antigen (PSA) test and prostate biopsy, an aging population, and the consequent increased risk of cancer. The possible contribution of physical and chemical carcinogens associated with environmental pollution and negative lifestyle changes should not be forgotten either. The mortality rate for prostate cancer remains stable, with a slight decline in recent years. The article provides an overview of trends in the incidence and mortality of prostate cancer in the Czech Republic and Europe. © 2016 Czech Medical Association J.E. Purkyne. All rights reserved.

Bisphenol A (BPA) [2,2-bis-(4-hydroxyphenyl) propane] is an important industrial agent, made by combining acetone and phenol, that is used extensively as a monomer in the production of polycarbonate plastics and as a precursor of epoxy resins. Micronucleus assays have served as an index of cytogenetic damage in in vivo and in vitro studies.We studied the genotoxic and cytotoxic effects of BPA on bovine peripheral lymphocytes in vitro. Lymphocyte cultures from two donors were exposed to four different concentrations of BPA (1×10 -4, 1×10-5, 1×10-6, and 1×10-7 mol.L-1) for 48 h. The highest concentration of BPA (1×10-4 mol.L-1) resulted in a significant increase in the number of micronuclei in comparison with the negative control (67.50±2.121/1,000 binucleated cells versus 36.0±5.657/1,000 binucleated cells in the DMSO control, P= 0.018). BPA did not affect the nuclear division index at any treatment concentrations. The present results thus demonstrate a significant genotoxic effect by BPA on bovine peripheral lymphocytes in vitro, only at the highest concentration. © The Society for In Vitro Biology 2014.

The authors trace the history of metformin and its clinical use to the present day. Recent insights into its mode of action and latest data from experimental and clinical medicine have unraveled novel properties of metformin, which may be particularly useful in the treatment of conditions other than diabetes. Results of ongoing clinical trials will show whether or not the hypoglycemic effect of metformin will become only one of the many to be employed in clinical practice.

Purpose. LINAC-based stereotactic radiosurgery (SRS) of posterior uveal melanoma is a conservative method to treat uveal melanoma. Methods. This was a retrospective clinic-based study of patients with posterior uveal melanoma in stage T2/T3 who underwent 1-day session SRS at LINAC accelerator or SRS plus combined methods from 2001 to 2008. Results. Thirty-nine patients with posterior uveal melanoma were treated with SRS (age 25-80 years, median 54 years). Median tumor volume at baseline was 0.6 cm3 (range 0.2-1.3 cm3). The therapeutic dose (TD) was 35.0 Gy, median of maximal dose applied was 49.0 Gy (range 37.0-60.0 Gy). Patient data were analyzed in groups: group 1, single SRS irradiation; group 2, SRS with subsequent endoresection or cyclectomy or additional transpupillary thermotherapy (TTT) or brachytherapy by Ru106 plaques; group 3a, enucleation after single SRS; group 3b, enucleation after SRS and endoresection/cyclectomy or TTT or brachytherapy Ru106. In patients with visual acuity of 20/40 or better, the median rate of best-corrected visual acuity (BCVA) decline was higher than that of the total and significantly higher than the rate of decline in the complementary group of patients with BCVA less than 20/40 (p=0.0077; Mann-Whitney U test). Conclusions. One-step LINAC-based SRS with a single dose 35.0 Gy is a method to treat middle-stage posterior uveal melanoma and to preserve the eye globe or as the first step of combined methods: irradiation before endoresection or cyclectomy. © 2011 Wichtig Editore.

The article deals with the selected parts of the writings of M. Tullius Cicero De natura deorum and Cato Maior De senectute dealing with medicine. It is an attempt to illustrate medical knowledge of educated people in ancient Rome. In its true sense, the above given writings have not a scientific character. However, the errors that the writings contain belong to the time when Marcus Tullius Cicero had lived. Cicero's knowledge in anatomy is given as an example. © 2008-2013 MeDitorial.

The article introduces an integrative psychoneurodevelopmental model of complex human brain and mind development based on the latest findings in prenatal and perinatal medicine in terms of integrative neuroscience. The human brain development is extraordinarily complex set of events and could be influenced by a lot of factors. It is supported by new insights into the early neuro-ontogenic processes with the help of structural 3D magnetic resonance imaging or diffusion tensor imaging of fetal human brain. Various factors and targets for neural development including birth weight variability, fetal and early-life programming, fetal neurobehavioral states and fetal behavioral responses to various stimuli and others are discussed. Molecular biology reveals increasing sets of genes families as well as transcription and neurotropic factors together with critical epigenetic mechanisms to be deeply employed in the crucial neurodevelopmental events. Another field of critical importance is psychoimmuno-neuroendocrinology. Various effects of glucocorticoids as well as other hormones, prenatal stress and fetal HPA axis modulation are thought to be of special importance for brain development. The early postnatal period is characterized by the next intense shaping of complex competences, induced mainly by the very unique mother - newborn's interactions and bonding. All these mechanisms serve to shape individual human mind with complex abilities and neurobehavioral strategies. Continuous research elucidating these special competences of human fetus and newborn/child supports integrative neuroscientific approach to involve various scientific disciplines for the next progress in human brain and mind research, and opens new scientific challenges and philosophic attitudes. New findings and approaches in this field could establish new methods in science, in primary prevention and treatment strategies, and markedly contribute to the development of modern integrative and personalized medicine. ©2013 Neuroendocrinology Letters.

Background: Despite very good prognosis patients with previously treated well-differentiated thyroid cancer (DTC) require lifelong monitoring for recurrent disease. Apart from neck ultrasonography (USG) two diagnostic tests play a central role in follow-up of these patients: radioiodine whole body scanning and serum thyroglobulin (Tg) measurement. The diagnostic value of both tests is most accurate during thyroid stimulating hormone (TSH) stimulation. Temporary discontinuation of thyroid hormone therapy was previously the sole effective approach for TSH-stimulated testing. However, hormone withdrawal was associated with the morbidity of severe hypothyroidism. The introduction of recombinant human TSH (rhTSH)-stimulated testing offers an alternative way. Recent clinical trials have shown that measurement of the rhTSH-stimulated serum Tg concentration (rhTSH-Tg) alone is the most sensitive way to detect residual or recurrent thyroid cancer. Objectives: The aim of the study was to investigate rhTSH-Tg in patients considered to be cured with already finished radioiodine treatment 1-3 years ago (routine follow-up) and in patients more years after radioiodine therapy with a new indefinite (mild) suspicion for DTC recurrence and to report the first experience with this diagnostic procedure in Slovakia. Patients and methods: RhTSH-Tg was examined in 84 patients (72 women and 12 men) clinically free of disease, 1-3 years after finishing radioiodine therapy. Second group consisted of 4 patients (2 women and 2 men) 5, 9, 12 and 38 years after 131I treatment with a mild suspicion of DTC recurrence. Results: RhTSH testing was well tolerated. No adverse events were detected. In the first group clinically free of disease undetectable rhTSH-Tg (<0.2 ng/ml) was found in 77 patients (91.7 %), Tg above diagnostic cutoff (>2 ng/ml) in 4 patients (4.8 %) and Tg in the range 0.6-2 ng/ml in 3 cases (3.6 %). In all patients of second group previous indefinite suspicion of DTC recurrence was confirmed by the rhTSH-Tg rise (2.9-7.3 ng/ml). Conclusion: In accordance with the literature rhTSH-Tg concentration in combination with neck USG has the highests sensitivity and negative predictive value in detecting residual or recurrent DTC (Tab. 1, Fig. 1, Ref. 14).

Pharmacological literature in the Late Antique period followed the Roman tradition and widely used Scribonius Largus and excerpts from the writings of Pliny the Elder. Literature was created both in the western part of the Roman Empire and in North Africa in Carthage. Manuals have been written about medicinal plants (Herbarius of Pseudo-Apuleius, De herba vettonica of Pseudo-Musa), for drugs obtained from the animal kingdom (Liber medicinae of Sextus Placitus) or documents containing both (De medicina of Cassius Felix, De medicamentis of Marcellus Empiricus). The contribution of this literature is the mediation of ancient knowledge into the Middle Ages.
