BACKGROUND/AIM The most sensitive indicators for detecting recurrence of well-differentiated thyroid cancer (DTC) are 131I whole body scintigraphy (WBS) and measurement of serum thyroglobulin (Tg). In order to perform it, it is necessary to raise the level of endogenous tiroid-stimulating hormon (TSH), which can be achieved by L-thyroxine withdrawal for 3-5 weeks or administration of recombinant human thyrotropin (rhTSH) without requiring the discontinuation of thyroid hormone therapy. The aim of this study was to assess the effect of rhTSH using in comparison to the traditional thyroid hormone withdrawal in the follow-up of patients with DTC. METHODS This retrospective study included 44 patients, mean age 48.8 years, with DTC divided into 2 groups. The group I consisted of patients (n = 31) in which the analysis in the follow-up (WBS with 131I, TSH, Tg and antiTgAt) made in the hypothyroid state, and group II patients (n = 13) in which they made after the administration of rhTSH. The presence of 13 symptoms and signs of hypothyroidism was investigated on the day of giving 131I. Quality of life was evaluated using a modified form: the quality of life scale (SF-36) completed on the day of giving 131I. RESULTS In both groups, serum TSH reached a very good stimulation level, but significantly higher in the group II (group I 30.3-101.5 microlU/mL, group II 68.6-192.0 microlU/mL, p < 0.05). In both groups, TSH-stimulated Tg was higher (group I 0.1-546.0 ng/mL, group II 0.1-7517 ng/mL) comapred to value during the L-thyroxine therapy (group I 0.1-495.0 ng/mL, group II 0.1-2785 ng/mL). There was no difference in technical quality of WBS obtained from both groups. The patients in the group I had attended 8-13 symptoms of hypothyroidism, while patients in group II did not have symptoms of hypothyroidism. The patients after application of rhTSH, showed statistically significantly better quality of life as compared with those who showed to have L-thyroxine withdrawal, (74-91 points vs 43-62 points; p < 0.05). The rhTSH was well tolerated, with nausea occurring in only one patient. CONCLUSION Administration of rhTSH in the follow-up of patients with DTC prevents the debilitating effects of hypothyroidism contributing to the maintenance of metabolic homeostasis of the organism and preserves the quality of life. RhTSH is safe, effective and easy to use, but is still an expensive product in our country.

BACKGROUND/AIM Speech motor mechanisms play a crucial role in the process of demutization, due to the fact that they cover all the elements of the successive development of spech production movements leading to speech formation (so-called kinesthesia in speach). The aim of this study was to estimate the impact of perceptual motor actions on the cognitive process of reading in 130 students in regular schools and schools for the deaf and hard-of-hearing children in the Republic of Serbia. METHODS Kostić and Vladisavljević test consisted of the ten levels weight was used for the assessment of reading speed. To assess understanding of text read by verbal responses, we used three-dimensional adapted reading test of Helene Sax. RESULTS The triage-articulation test for assessing reading speed (Kostié and Vladisavljević's test according to the weight of ten levels, revealed that students in regular schools statistically significantly faster read texts as compared to the deaf students. The results of the three-dimensional adapted reading test of Helena Sax, show that the words learned by deaf children exist in isolation in their mind, i.e., if there is no standard of acoustic performance for graphic image, in deaf child every word, printed or written, is just the sum of letters without meaning. CONCLUSION There is a significant difference in text reading speed and its understanding among the children who hear and the deaf and hard-of-hearing children. It is essential that in deaf and heard-of-hearing children education, apart from the development of speech, parallelly use the concept of semantic processing in order to get each word by the fullness of its content and the possibility of expanding its meaning in a variety of assets.

BACKGROUND Frequent use of Facebook and other social networks is thought to be associated with certain behavioral changes, and some authors have expressed concerns about its possible detrimental effect on mental health. In this work, we investigated the relationship between social networking and depression indicators in adolescent population. SUBJECTS AND METHODS Total of 160 high school students were interviewed using an anonymous, structured questionnaire and Back Depression Inventory - second edition (BDI-II-II). Apart from BDI-II-II, students were asked to provide the data for height and weight, gender, average daily time spent on social networking sites, average time spent watching TV, and sleep duration in a 24-hour period. RESULTS Average BDI-II-II score was 8.19 (SD=5.86). Average daily time spent on social networking was 1.86 h (SD=2.08 h), and average time spent watching TV was 2.44 h (SD=1.74 h). Average body mass index of participants was 21.84 (SD=3.55) and average sleep duration was 7.37 (SD=1.82). BDI-II-II score indicated minimal depression in 104 students, mild depression in 46 students, and moderate depression in 10 students. Statistically significant positive correlation (p<0.05, R=0.15) was found between BDI-II-II score and the time spent on social networking. CONCLUSIONS Our results indicate that online social networking is related to depression. Additional research is required to determine the possible causal nature of this relationship.

BACKGROUND Subjects that spend more time working on computers or watching television could have a higher body mass index. AIM To assess the relationship between time spent in front of a screen and studying, body mass index (BMI), smoking, and sleep duration among university students. MATERIAL AND METHODS A cross-sectional study of 734 randomly selected students aged 21 ± 2 years (450 females) that responded an anonymous, structured questionnaire about time spent watching television or in front of a computer, time spent studying, number of daily hours of sleep, smoking habits and number of daily meals. Body mass index was also calculated for all subjects RESULTS Among males, the number of daily sleep hours, time spent working with computers and number of daily meals were significantly higher and time spent studying was significantly lower than females. Nonsmokers ate a significantly higher number of meals and spent less time watching television. No association was observed between time spent in front of a screen and number of sleep hours of body mass index. CONCLUSIONS Men and smokers spend more time working in computers. There is no association between body mass index and time spent in front of screens.

<p>Skin lesions have a strong influence on the mental health. Literature indicates the complex interrelationships between psychosocial factors and psoriasis, which substantially reduce the quality of life of these patients. These interrelationships are based on numerous interactions that exist between the immune, nervous and endocrine systems and they are the basis of interactions that exist between mental and somatic health and the environment. Psychodermatology was developed as a new interdisciplinary field, a connection between psychiatry and dermatology. More than just cosmetic disfigurement, psoriasis is associated with various psychopathological problems that may have an impact on patients, their families and society. Numerous psychological disturbances occur in patients with psoriasis. Also, a significant psychiatric comorbidity was found in patients with psoriasis. Exacerbation of psoriasis leads to a deterioration of mental health. The treatment of psoriasis requires an interdisciplinary approach of a dermatologist and a psychiatrist. Various forms of psychological interventions have been proposed as a potentially useful addition to a standard pharmacological treatment of psoriasis.&nbsp;</p>

Fumagillin is an antibiotic derived from the fungus Aspergillus fumigatus. It has been used successfully for the treatment of intestinal microsporidiosis in HIV-positive humans, as well as in those suffering from intestinal amebiasis and microsporidial keratoconjunctivitis. In veterinary medicine it is approved for the treatment of microsporidiosis in bees and fish. In this research fumagillin was tested for the ability to provoke chromosomal aberrations in mouse bone marrow cells. BALB/c mice were administered fumagillin by gastric probe in doses of 5, 10 and 20 mg/kg b.w. Water-sugary syrup was the negative and cyclophosphamide (15 mg/kg b.w.) the positive control. Significantly increased frequencies (p<0.01 or p<0.001) of numerical chromosomal aberrations (aneuploidies and poliploidies) was observed both in the medium (10 mg/kg b.w.) and the highest (20 mg/kg b.w.) dose of fumagillin. Structural chromosomal aberrations (gaps, breaks and insertions) were noticeably more frequent in comparison to negative control only in the highest experimental dose of dycikloheksilamine. These results clearly showed that fumagillin in concetrations 10 and 20 mg/kg b.w. had a genotoxic potential in vivo.
