Hyperprolactinaemia especially affects women in reproductive age (90/100,000) but also often is diagnosed in menopause age and leads to disturbances in functioning of LH-RH neurons and, as a consequence, to a decrease of FSH and LH, which causes inhibition of oestradiol production. Prolactin is a peptide hormone, phylogenetically one of the oldest, stimulating cells of various organs, which is produced and secreted mainly by lactotrophic acidophilic cells of the anterior lobe of the pituitary. It influences the increase in the mass of the mammary glands, and stimulation and maintenance of lactation after delivery...

OBJECTIVES: REM sleep behavior disorder (RBD), with its main clinical symptoms of nightmares with dream-enacting behavior, is considered as a possible precursor of neurodegenerative disease. Obstructive Sleep Apnea Syndrome (OSAS) is known to be capable of provoking RBD-like symptoms by apneic event related arousals. The two sleep related pathologies must coincide in a relevant number of individuals because of overlapping prevalence in similar age groups. Until now RBD symptoms coexisting with OSAS are rarely described in scientific literature and in fact considered as OSAS mimicking RBD...

PURPOSE OF REVIEW: Non-motor symptoms in patients with Parkinson's Disease (PD) are better predictors of quality of life changes, caregiver burden, and mortality than motor symptoms. Levodopa has limited, and sometimes detrimental, effects on these symptoms. In this review we discuss recent evidence on pharmacological treatments for non-motor symptoms. RECENT FINDINGS: Breakthroughs have been made in the treatment of psychosis and sleep dysfunction. Pimavanserin has become the first FDA approved drug for PD psychosis...

A 43-year-old male patient with past medical history of diabetes mellitus (DM), end stage renal disease (ESRD) on hemodialysis (HD), congestive heart failure (CHF), obstructive sleep apnea (OSA), and chronic anemia presented with complaints of left thigh pain. A computerized tomogram (CT) of the thigh revealed evidence of edema with no evidence of a focal collection or gas formation noted. The patient's clinical symptoms persisted and he underwent magnetic resonance imaging (MRI) of his thigh which was reported to show small areas of muscle necrosis with fluid collection...

Introduction: Impaired sleep has been reported as an important non-motor feature in dystonia, but so far, subjective complaints have never been compared with nocturnal video-polysomnographic recording, which is the gold standard to assess sleep-related disorders. Methods: Twenty patients with idiopathic isolated cervical dystonia and 22 healthy controls underwent extensive clinical investigations, neurological examination and questionnaires screening for excessive daytime sleepiness and sleep-related disorders...

Microglia are the resident immune cells of the central nervous system (CNS) and they contribute to primary inflammatory responses following CNS injuries. The morphology of microglia is closely associated with their functional activities. Most previous research efforts have attempted to delineate the role of ramified and amoeboid microglia in the pathogenesis of neurodegenerative diseases. In addition to ramified and amoeboid microglia, bipolar/rod-shaped microglia were first described by Franz Nissl in 1899 and their presence in the brain was closely associated with the pathology of infectious diseases and sleeping disorders...

OBJECTIVE: Primary snoring (PS) and obstructive sleep apnea (OSA) not only affect the quality of sleep in a large number of young children, but have also been repeatedly associated with a variety of behavioral and cognitive problems. However, little is known about the potentially differing relationships of behavioral and cognitive pathology within the sleep disordered breathing (SDB) spectrum. METHOD: This study examined data from an enriched for snoring community sample of 631 children aged between 4 and 10 years...

Obesity is a major health problem that has become a global epidemic. Overweight and obesity are commonly associated with the development of several pathologies, such as insulin resistance, cardiovascular diseases, sleep apnea and several types of cancer, which can lead to further morbidity and mortality. An increased abdominal adiposity renders overweight and obese individuals more prone to metabolic and cardiovascular problems. In this sense, excess adiposity leads to several changes in the biology, morphology and function of the adipose tissue, such as adipocyte hypertrophy and hyperplasia, adipose tissue inflammation and fibrosis and an impaired secretion of adipokines, contributing to the onset of obesity-related co-morbidities...

An assessment of suicidal behaviors in the dermatology patient may be necessary in several situations: (1) in the presence of psychiatric comorbidity (major depressive disorder, body dysmorphic disorder, substance use disorder, posttraumatic stress disorder), encountered in up to 30% of dermatology patients; (2) when dermatologic symptoms ("dysmorphophobia," dermatitis artefacta) represent psychiatric pathologic conditions; (3) when psychosocial stressors (bereavement, interpersonal violence) increase the risk of suicidal behavior and exacerbate stress-reactive dermatoses (psoriasis, acne); (4) in the presence of high disease burden (chronicity, increased disease severity); (5) in instances of significant pruritus or chronic sleep disruption; (6) in the presence of facial lesions or facial scarring; (7) when social exclusion or feelings of alienation arise secondary to the skin disorder; (8) with use of medications (retinoids, biologics) for which suicidal behavior has been implicated as a possible side effect; and (9) when treating psychiatric patients experiencing a serious reaction to psychotropic medications (eg, Stevens-Johnson syndrome and anticonvulsants)...

As women age and go through menopause, they suffer a higher incidence of sleep disorder, cardiovascular morbidity and mortality. In addition, evidences suggested that sleep disorder was an important pathological indicator for coronary heart disease. However, the relationship between different menopausal status, sleep disorder and cardiovascular diseases was unclear. Thus, we aim to assess the association between sleep disorder with arterial stiffness in females of 40-60 years free of cardiovascular diseases through self-administered Pittsburgh Sleep Quality Index (PSQI) and brachial-ankle pulse wave velocity (baPWV)...

OBJECTIVES: This study exclusively aimed to clinically assess which symptom pattern discriminates primary depression from depression-secondary to-schizophrenia. METHODS: A total of 98 patients with primary depression and 71 patients with secondary-to-schizophrenia depression were assessed for identifying the clinical phenomena of depression. Diagnosis of schizophrenia was confirmed by Mini International Neuropsychiatric Interview. Each participant was, however, assessed by Patient Health Questionnaire-9 as well as Calgary Depression Scale for Schizophrenia (CDSS) for possible concurrent depressive symptoms...

Cerebrovascular reactivity (CVR) is the cerebral hemodynamic response to a vasoactive substance. Breath-hold (BH) induced CVR has the advantage of being non-invasive and easy to implement during magnetic resonance imaging (MRI). We systematically reviewed the literature regarding MRI measurement of BH induced CVR. The literature was searched using MEDLINE with the search terms breath-hold; and MRI or cerebrovascular reactivity. The search yielded 2244 results and 54 articles were included. Between-group comparisons have found that CVR was higher among healthy controls than patients with various pathologies (e...

Introduction Obstructive Sleep Apnea Syndrome (OSAS) is characterized by recurrent episodes of prolonged partial or complete obstruction of the upper airways. Several study groups studied the effect of snoring and OSAS on auditory function, showing an increase in the incidence of hearing loss in apneic patients, an earlier onset and/or a degree of hearing loss deeper than in peers. The aim of our study is to evaluate the audiological performance of a population of simple-snoring patients and patients suffering from mild OSAS, and the impact that such pathological condition can have on the auditory function, considering the significant levels of chronic noise...

Mutations of the retromer component Vps35 and endosomal kinase LRRK2 are linked to autosomal dominant forms of familial Parkinson's disease (PD). However, the physiological and pathological roles of Vps35 and LRRK2 in neuronal functions are poorly understood. Here, we demonstrated that the loss of Drosophila Vps35 (dVps35) affects synaptic vesicle recycling, dopaminergic synaptic release and sleep behavior associated with dopaminergic activity, which is rescued by the expression of wild-type dVps35 but not the PD-associated mutant dVps35 D647N...

Mesopontine tegmental nuclei such as the cuneiform, pedunculotegmental, oral pontine reticular, paramedian raphe and caudal linear raphe nuclei, are deep brain structures involved in arousal and motor function. Dysfunction of these nuclei is implicated in the pathogenesis of disorders of consciousness and sleep, as well as in neurodegenerative diseases. However, their localization in conventional neuroimages of living humans is difficult due to limited image sensitivity and contrast, and a stereotaxic probabilistic neuroimaging template of these nuclei in humans does not exist...

TRPV3 is a non-selective cation channel activated by temperatures above 33oC, and is reported localized in keratinocytes and nervous tissue. In order to investigate a role for TRPV3 in pain modulation, we conducted a series of in vivo electrophysiological studies on spinal and brain nociceptive neurons. Structurally diverse TRPV3 receptor antagonists reduced responses of spinal WDR neurons to low-intensity mechanical stimulation in neuropathic rats, but only CNS penetrant antagonists decreased elevated spontaneous firing...

The K-complex (KC) is one of the hallmarks of Non-Rapid Eye Movement (NREM) sleep. Recent observations point to a drastic decrease of spontaneous KCs in Alzheimer's disease (AD). However, no study has investigated when, in the development of AD, this phenomenon starts. The assessment of KC density in mild cognitive impairment (MCI), a clinical condition considered a possible transitional stage between normal cognitive function and probable AD, is still lacking. The aim of the present study was to compare KC density in AD/MCI patients and healthy controls (HCs), also assessing the relationship between KC density and cognitive decline...

Decades of research on neurodegenerative diseases such as Parkinson's disease (PD) have shifted our focus from clinical symptomatic stages to one step earlier, the prodromal stage. There is convincing evidence showing that sleep disorders such as excessive daytime somnolence, insomnia, obstructive sleep apnea, and particularly REM sleep behavior disorder (RBD) are potential prodromal features starting years and decades before conversion to PD. This review aims to provide an overview on various sleep disorders as prodromal features of PD...

Obstructive sleep apnea (OSA) has been linked to increased mortality in pulmonary fibrosis. Its key feature, chronic intermittent hypoxia (CIH), can lead to oxidative stress and inflammation, known to lead to fibrotic pathology in other organs. We tested the effects of CIH in an animal model of bleomycin-induced lung fibrosis. Sprague Dawley rats were instilled intratracheally with bleomycin (Blm) or saline (Sal), and exposed to CIH or normal air (Norm) for 9 or 30 days. Pulmonary function was tested and lungs were harvested for histological and molecular analyses...

Sleep disorders have previously been connected with the neurodegenerative pathology of Alzheimer's disease (AD) due to the aggregation of β-amyloid(Aβ)peptides and tau proteinsinduced by sleep deprivation (SD). However, the underlying mechanisms remain unclear. Therefore, this study was performed to clarify how Aβ-related metabolism is regulated after SD. Three-month-old Sprague-Dawley rats (250-300g) were randomly divided into 5 groups: two SD groups(i.e.,SD-2d and SD-4d), two platform control groups(i...
