The Effect of Methylphenidate Treatment on Olfactory Function in Children and Adolescents With ADHD.

OBJECTIVE: This study aimed to research whether there is an olfactory disorder in ADHD, and if so, what is the effect of methylphenidate on this condition. METHOD: This is a cross-sectional study aiming to evaluate olfactory threshold, identification, discrimination and threshold, discrimination, and identification (TDI) scores in 109 children and adolescents, 33 of whom have ADHD without medication, 29 with ADHD with medication and 47 control groups. RESULT: In the post hoc tests, the mean odor discrimination test, the mean odor identification test, and the mean TDI scores of the unmedicated ADHD group were significantly lower than those of the other two groups, and that the mean odor threshold test scores of the medicated ADHD group were significantly lower than those of the control and unmedicated groups. CONCLUSION: Olfactory function could be a useful tool to monitor treatment effects and may be a promising candidate as a biomarker in ADHD.

Evaluation of cognitive disengagement syndrome in children with obsessive-compulsive disorder: Clinical implications.

Cognitive disengagement syndrome (CDS) has been found to be associated with internalizing symptoms. Yet, no study thus far has focused on whether there is an association between obsessive-compulsive disorder (OCD) and CDS. The purpose of this study is to examine the symptom frequency and clinical implications of CDS in children with OCD. The study included sixty-one children with OCD and sixty-six typically developing children. Children were evaluated by a semi-constructed diagnosis interview, Obsessive-Compulsive Inventory, Barkley Child Attention Scale, and Stroop test. The frequency of elevated symptoms of CDS, and total time, total error, and total correction scores of the Stroop test were significantly higher in the OCD group compared to the controls. Elevated CDS symptoms were significantly associated with higher OCD symptom prevalence and poorer performance on the Stroop Test. Moreover, poor insight, hoarding symptoms, mental compulsions, and ADHD comorbidity were significantly higher in those with elevated CDS symptoms than in those without CDS in the OCD group. The findings of this study provide clinical implications that CDS symptoms may contribute to deficits in attentional orientation, conceptual flexibility, and cognitive processing speed in OCD.

The effects of sexual counseling and pelvic floor relaxation on sexual functions in women receiving vaginismus treatment: a randomized controlled study.

INTRODUCTION AND HYPOTHESIS: The purpose of this study is to determine the effects of sexual counseling and pelvic floor relaxation on sexual functions in women receiving vaginismus treatment. METHODS: A total of 34 women at the vaginismus treatment stage, including 17 in the experiment group and 17 in the control group, were included in the study with a randomized controlled design. In addition to the routine treatment protocol, women in the experiment group were provided with pelvic relaxation and sexual counseling based on the Information, Motivation, Behavior (IMB) model consisting of four sessions. The control group received the routine treatment protocol. The assessments were made at the 3rd week and 2nd month after coitus. The women filled out an Information Form, the validated Female Sexual Function Index (FSFI), and the Vaginal Penetration Cognition Questionnaire (VPCQ). RESULTS: The mean age of the women was 27.59±5.32, and their mean duration of marriage/relationship was 33.44±12.11 months. After the treatment statistically significant increases were observed in the total FSFI scores and the desire, arousal, and pain dimension scores of the experiment group in comparison with the control group (p<0.05). In the VPCQ total scores, there was a significant reduction in the experiment group in comparison with the control group and after the treatment in comparison with before the treatment (p<0.01). CONCLUSIONS: The sexual counseling based on the IMB model and pelvic relaxation interventions provided to the women who were receiving vaginismus treatment affected their sexual function positively. It may be recommended to conduct comparative studies with a broader sample and different models.

SIRT1, MMP-9 and TIMP-1 levels in children with specific learning disorder.

BACKGROUND: Specific Learning Disorder (SLD) is a common developmental and neurobiological disorder of childhood characterized by impairment of functionality in one or more areas such as reading, writing, mathematics, listening, speaking, and reasoning. The etiology of SLD is still not fully understood. The aim of this study was to evaluate children with SLD to investigate the potential role of MMP-9, TIMP-1 and SIRT-1, which have important roles in synaptic plasticity, cognitive functions, learning and memory, and are known to be associated with various psychiatric disorders. METHODS: The study was conducted with 44 outpatients aged 8-14 years who were diagnosed with SLD according to DSM-5 in the outpatient clinic and a control group of 44 age, gender and education level-matched healthy children. The groups were compared in respect of serum levels of MMP-9, TIMP-1 and SIRT-1, evaluated using the ELISA method. RESULTS: Serum MMP-9 levels were significantly lower in children in the SLD group than in the control group, while TIMP-1 was higher. No difference was determined between the groups in respect of the SIRT1 levels. SLD severity was negatively correlated with MMP-9 levels and positively correlated with TIMP-1 levels. CONCLUSIONS: MMP-9 appear to contribute to hippocampal-dependent memory and learning by modulating long-term synaptic plasticity. The findings of this study also reinforce the idea that deregulation of the MMP-9/TIMP-1 ratio may impact learning and play a role in SLD. These findings will help to elucidate the etiology of SLD. Furthermore, understanding molecular pathways can contribute to the discovery of certain biomarkers in SLD pathogenesis and the development of new treatment possibilities.

Effect of the COVID-19 pandemic and social distancing measures on the sexual functions of women treated for vaginismus (genitopelvic pain/penetration disorder).

INTRODUCTION AND HYPOTHESIS: Female sexual function is influenced by the emotional and hormonal state. COVID-19 has been the major global health crisis of our time with high psychosocial impact. Vaginismus is a form of female sexual dysfunction and a subset of genitopelvic pain/penetration disorder in which any form of vaginal penetration is painful or impossible. Our aim was to evaluate the effect of the COVID-19 pandemic on sexual function of women treated for vaginismus. MATERIALS AND METHODS: All women treated using dilators between 2018-2019 were included. Data obtained 3 months after comfortable penetration and during the pandemic via telephone interview were compared. The Female Sexual Function Index (FSFI), Golombok-Rust Inventory of Sexual Satisfaction (GRISS), and Beck Depression Inventory (BDI) were used to evaluate sexual function and depression. Frequency of sexual intercourse and pain was compared using a visual analogue scale. RESULTS: Seventy-seven women were included. Mean duration of treatment and number of treatment sessions were 3.5 ± 2.6 months and 4.2 ± 2.6, respectively. There were significant improvements in the FSFI desire, arousal, orgasm, and pain subscales and total score and in the GRISS infrequency, noncommunication, avoidance, non-sensuality, and vaginismus subscales and total score during the pandemic. The GRISS dissatisfaction and anorgasmia subscales and BDI score significantly worsened. Mean frequency of sexual intercourse was 2.3 ± 1.8/week and did not change significantly. Pain scores decreased during the pandemic (2.7 ± 2.8) compared to post-treatment (6.2 ± 2.9). CONCLUSION: Although frequency of sexual intercourse was not affected and pain scores and FSFI total and subscale scores improved, satisfaction and orgasm were adversely affected, which may be attributed to increased stress and anxiety during the pandemic.

Evidence supporting the role of telomerase, MMP-9, and SIRT1 in attention-deficit/hyperactivity disorder (ADHD).

Growing evidence suggests that telomeres, telomerase, matrix metalloproteinase-9 (MMP-9), and SIRT1 (sirtuin1) are involved in the pathophysiology of neuropsychiatric and neurodevelopmental disorders. However, whether these molecules are contributors to attention-deficit/hyperactivity disorder (ADHD) has been little explored and poorly understood. This study aimed to determine the potential role of telomerase, MMP-9, and SIRT1 in children with ADHD. The study was performed on 46 children with ADHD aged between 8 and 14 and 43 healthy children matching in age and gender. Children were evaluated by Kiddie-Sads-Present and Lifetime Version, Conners' Parent Rating Scale-Revised Short Form (CPRS-RS) and Stroop test. Serum telomerase, MMP-9, and SIRT1 levels were measured by a quantitative sandwich enzyme-linked immunosorbent assay. MMP-9 and telomerase levels were significantly higher and SIRT1 levels were significantly lower in patients with ADHD than those of controls. All three molecules were significantly associated with both the severity of ADHD symptoms and cognitive functions. This is the first attempt to indicate that the important role of telomerase, MMP-9, and SIRT1 in ADHD, and the association of all these molecules with the severity of ADHD and cognitive functions, but future studies are required to verify these results.
