INTRODUCTION: Intrauterine Device (IUD) is the most preferred modern contraceptive method in Turkey. Female Sexual Dysfunction (FSD) is defined as lack of one or more of the components in the sexual response cycle which includes sexual desire, impaired arousal and inability achieving an orgasm or pain with intercourse. FSD has multi-factorial aetiology. Advanced age and menopause, fatigue and stress, psychiatric and neurologic disease, childbirth, pelvic floor or bladder dysfunction, endometriosis, uterine fibroids, hypertension obesity, medication and substances, hormonal contraceptives, relationship factors are known risk factors for FSD...

INTRODUCTION: Hypoactive Sexual Desire Disorder (HSDD) is defined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Revised (DSM-IV-TR) as persistent deficient sexual fantasies and desire for sexual activity that causes marked distress or interpersonal difficulty. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), HSDD has been subsumed by Female Sexual Interest/Arousal Disorder. However, decades of research based on DSM-IV-TR HSDD criteria form the foundation of our understanding of the essential symptom of distressing low sexual desire, its epidemiology, clinical management, and treatment...

INTRODUCTION: Epidemiologic research in female sexual dysfunction (FSD) has gained momentum in recent years, particularly in clinical populations and in menopausal women. However, sexual dysfunction also affects premenopausal women in general populations. Previous literature reviews have been unable to quantify the burden of FSD in general populations. This has been due in part to different definitions of dysfunction, heterogeneous study design, and the wide variety of measurement tools used...

Plane-parallel ionisation chambers are regularly used to conduct relative dosimetry measurements for therapeutic kilovoltage beams during commissioning and routine quality assurance. This paper presents the first quantification of the polarity effect in kilovoltage photon beams for two types of commercially available plane-parallel ionisation chambers used for such measurements. Measurements were performed at various depths along the central axis in a solid water phantom and for different field sizes at 2 cm depth to determine the polarity effect for PTW Advanced Markus and Roos ionisation chambers (PTW-Freiburg, Germany)...

Female sexual dysfunction (FSD) and quality of life (QOL) are both multidimensional and have a bidirectional relationship across the reproductive life span and beyond. Methodological difficulties exist in estimating the real prevalence of FSD because it is hard to determine the level of distress associated with sexual symptoms in a large-scale survey. Approximately 40-50% of all women report at least one sexual symptom, and some conditions associated with hormonal changes at menopause, such as vulvovaginal atrophy (VVA) and hypoactive sexual desire disorder (HSDD), have a significant impact on sexual function and QOL...

We report the case of a 24-year-old man who presented with pustules, atrophic scars, and alopecia on the scalp, along with follicular keratotic papules on the cheeks, chest, abdomen, back, lateral upper arms, thighs, and axillae, of 6 years' duration. A diagnosis of folliculitis spinulosa decalvans (FSD) was made based on the clinical manifestation and histopathological findings. Dental examination also revealed dental anomalies and a fissured tongue, which are not known to be related to FSD. We provide an overview of the characteristic findings of FSD as well as a review of previously reported cases...

BACKGROUND: The appropriate managing center for adolescent trauma patients is debated. We sought to determine whether outcome differences existed for adolescent severe traumatic brain injury (sTBI) patients treated at pediatric versus adult trauma centers. We hypothesized that no difference in mortality, functional status at discharge (FSD) or overall complication rate would be observed between center types. METHODS: All adolescent trauma patients (aged 15-17 years) presenting with isolated sTBI (head Abbreviated Injury Scale [AIS] score ≥3; all other AIS body region scores ≤2) to accredited level I-II trauma centers in Pennsylvania from 2003-2015 were extracted from the Pennsylvania Trauma Outcome Study database...

INTRODUCTION: The occurrence of female sexual dysfunction (FSD) in patients with major depressive disorder (MDD) receiving selective serotonin reuptake inhibitors (SSRIs) treatment gives negative impacts on patients' quality of life and causes treatment discontinuation. We aimed to investigate whether genetic polymorphism of identified candidate gene is associated with FSD in our study population. METHODS: This is a cross-sectional study. A total of 95 female patients with MDD who met the criteria of the study were recruited and were specifically assessed on the sexual function by trained psychiatrists...

INTRODUCTION: A nomenclature is defined as a classification system for assigning names or terms in a scientific discipline. A nosology more specifically provides a scientific classification system for diseases or disorders. Historically, the nosologic system informing female sexual dysfunction (FSD) has been the system developed by the American Psychiatric Association in its Diagnostic and Statistical Manual of Mental Disorders (DSM-III through DSM-5). Experts have recognized limitations of its use in clinical practice, including concerns that the DSM-5 system does not adequately reflect the spectrum and presentation of FSD...

Small proteins provide good model systems for studying the fundamental forces that control protein folding. Here, we investigate the folding dynamics of the 28-residue zinc-finger mutant FSD-1, which is designed to form a metal-independent folded ββα-motif, and which provides a testing ground for proteins containing a mixed α/β fold. Although the folding pathway of FSD-1 has been actively studied, the folding mechanism remains largely unclear. In particular, it is unclear in what stage of folding the α-helix is formed...

Mechanical disintegration of sludge through ultrasonication demands high energy and cost. Therefore, in the present study, a comprehensive investigation was performed to analyze the potential of a novel method, fenton mediated sonic disintegration (FSD). In FSD process, extracellular polymeric substance (EPS) of sludge was first removed via fenton treatment. It was subsequently disintegrated via ultrasonication. Energetic assessment and economic analysis were then performed using net energy and cost gain (spent) as key factor to evaluate the practical viability of the FSD process...
