Compressive Optic Neuropathy Caused by Orbital Non-Hodgkin's Lymphoma

Purpose. To present a unique case of Non-Hodgkin's-Lymphoma- (NHL) associated compressive optic neuropathy. Method. An 89-year-old male presenting with acute unilateral visual loss and headache. Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasal sinus mass compressing the optic nerve. Conclusion. Paranasal sinus malignancies occasionally present to the ophthalmologist with signs of optic nerve compression and must be included in the differential diagnosis of acute visual loss

The relationship between Self-Esteem and sexual Self-Concept in people with Physical-Motor disabilities

Background: Self-esteem is the value that the individuals give themselves, and sexual self-concept is also a part of individuality or sexualself. Impairment or disability exists not only in the physical body of disabled people but also in their attitudes. Negative attitudes affect the mental health of disabled people, causing them to have lower self-esteem. Objectives: This study aimed to examine the relationship between self-esteem and sexual self-concept in people with physical-motor disabilities. Patients and Methods: This cross-sectional study was conducted on 200 random samples with physical-motor disabilities covered by Isfahan Welfare Organization in 2013. Data collection instruments were the Persian Eysenck self-esteem questionnaire, and five domains (sexual anxiety, sexual self-efficacy, sexual self-esteem, sexual fear and sexual depression) of the Persian multidimensional sexual selfconcept questionnaire. Because of incomplete filling of the questionnaires, the data of 183 people were analyzed by the SPSS 16.0 software. Data were analyzed using the t-test, Man-Whitney and Kruskal-Wallis tests and Spearman correlation coefficient. Results: The mean age was 36.88 ± 8.94 years for women and 37.80 ± 10.13 for men. The mean scores of self-esteem among women and men were 15.80 ± 3.08 and 16.2 ± 2.90, respectively and there was no statistically significance difference. Comparison of the mean scores of sexual anxiety, sexual self-efficacy, sexual self-esteem, sexual fear and sexual depression among men and women showed that women scored higher than men in all domains. This difference was statistically significant in other domains except the sexual self-esteem (14.92 ± 3.61 vs. 13.56 ± 4.52) (P < 0.05). The Kruskal-Wallis test showed that except for sexual anxiety and sexual self-esteem, there was a statistical difference between other domains of people’s sexual self-concept and degree of disability (P < 0.05). Moreover, Spearman coefficient showed that there was only a correlation between men’s sexual anxiety, sexual self-esteem and sexual self-efficacy with their self-esteem. This correlation was positive in sexual anxiety and negative in two other domains. Conclusions: Lack of difference in self-esteem of disabled people in different degrees of disability and in both men and women suggests that disabled people should not be presumed to have low self-esteem, and their different aspects of life should be attended to, just like others. Furthermore, studies should be designed and implemented based on psychological, social and environmental factors that can help disabled people to promote their positive sexual self-concept through marriage, and reduce their negative self-concept. © 2015 Iranian Red Crescent Medical Journal

Effects of mistuning on dynamic behavior of nonlinear cyclic systems with lump masses and cubic nonlinearity

Mistuning in cyclic symmetric systems increases severely the forced response of system and splits the modes. This paper concerns with nonlinear behavior of mistuned cyclic systems. A nonlinear, mistuned model based on the method of multiple scales is proposed and formulated in which nonlinearity and mistuning parameter is assumed to be in of low order. Next, two mistuned systems were considered and solved by the multiple scale technique. Numerical results demonstrate that mistuning can lead to repeating and scattering of jump phenomena during the excitation frequency whereas in tuned cyclic system it occurs simultaneously (synchronously).Peer ReviewedPostprint (published version

Self-esteem, general and sexual self-concepts in blind people

Background: People with visual disability have lower self-esteem and social skills than sighted people. This study was designed to describe self-esteem and general and sexual self-concepts in blind people. Materials and Methods: This was a cross-sectional study, conducted in the Isfahan University of Medical Sciences in 2013-2014. In this study, 138 visually impaired people participated from Isfahan Province Welfare Organization and were interviewed for measuring of self-esteem and self-concept using Eysenck self-esteem and Rogers’ self-concept questionnaires. The correlation between above two variables was measured using Statistical Package for the Social Sciences (SPSS) software by Pearson correlation test. Results: Mean [± standard deviation (SD)] age of patients was 30.9 ± 8 years. The mean (±SD) of general self-concept score was 11 ± 5.83. The mean (±SD) of self-esteem score was 16.62 ± 2.85. Pearson correlation results showed a significant positive correlation between self-esteem and general self-concept (r = 0.19, P = 0.025). The mean of sexual self-concept scores in five subscales (sexual anxiety, sexual self-efficacy, sexual self-esteem, sexual fear, and sexual depression) were correspondingly 11 ± 4.41, 19.53 ± 4.53, 12.96 ± 4.19, 13.48 ± 1.76, and 5.38 ± 2.36. Self-esteem and self-concept had significant positive correlation with sexual anxiety (r = 0.49; P < 0.001) (r =-.23; P < 0.001) and sexual fear (r = 0.25; P = 0.003) (r = 0.18; P = 0.02) and negative correlation with sexual self-efficacy (r =-0.26; P = 0.002) (r =-0.28; P = 0.001) and sexual-esteem (r =-0.34; P < 0.001) (r =-0.34; P < 0.001). Conclusion: Self-esteem and self-concept had significant correlation with sexual anxiety and sexual fear; and negative correlation with sexual self-efficacy and sexual-esteem. © 2015 Journal of Research in Medical Sciences

Effects of Virtual Emotion Regulation Training on Positive and Negative Sexual Self-Concept of Diabetic Married Women Covered by Comprehensive Health Centers in Gorgan, Iran

Abstract Background: Sexual self-concept is an individual's perception of his/her sexual feelings and actions, which can be affected by chronic diseases, including diabetes. As a biological and psychological crisis, diabetes can cause mood changes. The present study was conducted to determine the effects of virtual emotion regulation training on the positive and negative sexual selfconcept of diabetic married women. Methods: An interventional study was conducted on women with type 2 diabetes covered by the comprehensive health service centers of Gorgan (Iran) in 2019. Overall, 36 eligible diabetic women were enrolled via available sampling. The subjects were assigned to an intervention group (n=19) and a control group (n=17) through four-block allocation and random selection without placement. Virtual emotion regulation training was held during 4 sessions, once a week, for the intervention group. Both groups completed the Persian version of Beck’s Depression Inventory and Snell’s Multidimensional Sexual Self-Concept Questionnaire at baseline, immediately after the last virtual training session, and one month after the last training session. Data were analyzed using ANOVA and Bonferroni's post hoc test at a significance level of 0.05. Results: The mean score of positive sexual self-concept of patients after the last training session was 133.68 ± 18.91in the intervention and 131.17 ± 18.86 in the control group. The mean score of positive sexual self-concept of patients one month after the training was 10± 9.51in the intervention group and 15.17 ± 11.92in the control group. The mean score of negative sexual self-concept of patients after the last training session was 10.42± 10.04 in the intervention and 14.52± 14.39 in the control group. The interaction effects of time and group on the positive sexual self-concept did not differ significantly (P=0.316). The group effect was also not statistically significant (P=0.58). The interaction effects of time and group on the negative sexual self-concept were significant (P=0.023), and the group effect was not statistically significant (P=0.47). Conclusion: The significant interaction of time and group on negative sexual self-concept indicates that the negative sexual selfconcept in diabetic women has been affected by the intervention. Given the significant effects of virtual emotion regulation training on the management of negative emotions, this type of intervention can be beneficial for improving the health of diabetic women

Bearings coefficients effects on chaotic and bifurcation behavior of flexible rotor systems subjected to rub-impact

This study investigates the influence of end-support conditions on the chaotic and bifurcation behavior of a rotating flexible shaft-disk system. The system is modeled as a continuous shaft with a rigid disk in its mid span whilst supported by multi-coefficients bearings. Both Coriolis and centrifugal effects due to shaft flexibility are included. The partial differential equations of motion are extracted using the Rayleigh beam theory and the assumed mode method is used to discretize them in order to be solved numerically. The analytical tools used in this work include time series, phase plane portrait, power spectrum, Poincaré map, bifurcation diagrams, and Lyapunov exponents. The main objective of the present study is to investigate the effects of end-supports stiffness and damping coefficients on the chaotic vibration behavior of a rotating system. Periodic, sub-harmonic, quasi-periodic, and chaotic states have been observed for each case. As demonstrated, inclusion of the bearing effects can primarily change the speed ratios at which rub-impact occurs. The principal and cross-coupling stiffness and damping coefficients have quite different effects in the chaotic behavior of the system

Effects of dietary crude protein and calcium/ phosphorus content on growth, nitrogen and mineral retention in broiler chickens

This experiment was conducted to examine the effect of three levels of crude protein (CP) (NRC, 15% more than NRC and 15% less than NRC) and three levels of Ca and available P (Av. P) (NRC, 15% more than NRC and 15% less than NRC) on performance of broilers from hatching until 21 days of age. The experimental design was a completely randomized design (CRD), with a 3 × 3 factorial arrangement of nine dietary treatments. Each treatment combination had four replicate pens (10 birds per pen). Results of this experiment showed that CP content had no significant effect on feed and water intake. However, body weight gain (BWG) significantly reduced and FCR increased (P &lt; 0.05) by 15% change in CP content of diet. Fifteen percent increase in mineral content of diets had no significant effect on feed intake. However, increase in Ca and Av. P significantly increased BWG and resulted in an improved feed conversion ratio (FCR) and increased water intake. There was an interactive effect of CP by Ca and Av. P levels on feed intake, BWG and FCR. A change in CP or mineral content of the diets had no significant effect on blood parameters except for potassium concentration (K+). Reducing CP, Ca and Av. P content of the diet significantly (P &lt; 0.001) increased P, Ca and N retention. Reduction in CP content of the diet led to a decrease in length, P and tibia bone ash. There was an interactive effect of CP by Ca and Av. P on the retention of Ca, N and ash of tibia bone.Key words: Crude protein, Ca and Av. P levels, broilers, N retention

Self-Awareness Counseling on Quality of Life of Menopausal Women

Background: Counseling interventions are among the available strategies to improve the menopausal quality of life and self-awareness counseling is effective in improving adaptation, self-confidence and quality of life. Therefore, the present study aimed to examine effects of self-awareness counseling on quality of life of menopausal women in Gorgan, Iran. Methods: In this clinical trial, we examined 52 menopause women referred to health centers of Gorgan, Iran in 2018. Data collection tools included a demographic characteristics form and the menopause-specific quality of life questionnaire. First, the control group completed the data collection tools at the beginning of the study and 6 and 10 weeks after the first session. Then the intervention group completed the tools at base line and participated in six 45-60-minute self-awareness-based group counseling sessions, once a week. After that, they were completed questionnaire, immediately and a month after the end of the intervention. Data were expressed as mean ± standard deviation. Results: In the intervention group, the baseline mean scores of menopausal quality of life and its vasomotor, physical, psychosocial and sexual domains were 55.69±19.47, 5.30±4.57, 30.26±12.24, 12.15±6.64 and 7.96±5.34, respectively. A month after the intervention, the mean scores of menopausal quality of life (30.42±19.64) and its vasomotor (2.65±2.33), physical (16.38±8.64), psychosocial (7.19±4.63) and sexual (4.19±3.42) domains increased significantly in the intervention group (p=0.001). In between group comparison, except for the psychosocial domain, the mean scores of quality of life and its various domains showed a statistically significant difference in one month after the intervention (P=0.001). Conclusion: The menopausal quality of life and its various domains improved one month after the end of self-awareness counseling. Therefore, we recommend offering self-awareness counseling in health centers for improving the quality of life of menopausal women

Evaluating Correlation of General Self-Concept with Sexual Self-Concept in Infertile Women

Background: General self-concept refers to a set of feelings and perceptions toward oneself, and sexual self-concept is defined as individual's perception of his/her sexual feelings and actions. These two concepts are affected by various life problems, including infertility. The present study aimed to evaluate correlation of general self-concept and sexual self-concept in infertile women. Methods: This descriptive correlational study was carried out on all infertile women who visited the Gorgan Infertility Center in 2018. Overall, 105 eligible infertile women were included in the study via convenience sampling. Data were collected using Persian versions of the Rogers self-concept questionnaire and the Snell sexual self-concept questionnaire. Data were analyzed using the Pearson and Spearman's correlation tests in SPSS 16 and at significance of 0.05. Results: Mean age of subjects was 28.88±5.14 years (range: 17 and 40 years). Based on the findings, 19% of the participants had normal general self-concept, 31.4% had moderate self-concept, and 49.5% had weak self-concept. Mean scores of positive sexual self-concept, negative self-concept and situational sexual self-concept were 118.9±24.85, 13.33±8.94 and 41.98±10.53, respectively. There was no correlation between general self-concept and different dimensions of sexual self-concept of the infertile women. Conclusion: Due to the lack of correlation between general self-concept and sexual self-concept in infertile women, it is suggested to conduct evaluations and interventions on the general and sexual self-concepts of the participants separately
