Study Objectives: Sleep fragmentation (SF) is highly prevalent and has emerged as an important contributing factor to obesity and metabolic syndrome. We hypothesized that SF-induced increases in protein tyrosine phosphatase-1B (PTP-1B) expression and activity underlie increased food intake, inflammation, and leptin and insulin resistance. Methods: Wild type (WT) and ObR-PTP-1b-/- mice (Tg) were exposed to SF and control sleep (SC), and food intake was monitored...

INTRODUCTION: Iron overload leads to multiple organ damage including endocrine organ dysfunctions. Hypogonadism is the most common non-diabetic endocrinopathy in primary and secondary iron overload syndromes. AIM: To explore the molecular determinants of iron overload-induced hypogonadism with specific focus on hypothalamic derangements. A dysmetabolic male murine model fed iron-enriched diet (IED) and cell-based models of gonadotropin-releasing hormone (GnRH) neurons were used...

Our previous studies have demonstrated that prenatal caffeine exposure (PCE) induced an intrauterine programming of hypothalamic-pituitary-adrenal axis (HPAA)-associated neuroendocrine metabolism in 3-month-old offspring rats. In this study, we aimed to confirm this programming disorder and high susceptibility to metabolic syndrome (MS) in 10-month-old female PCE offspring with postnatal catch-up growth. We found that PCE female offspring rats showed decreased bodyweight but a higher rate of weight gain after birth...

BACKGROUND: Polycystic ovary syndrome (PCOS) is commonly characterized by obesity, insulin resistance (IR), hyperandrogenemia and hirsutism. Following the reported relationship between phoenixin-14 and gonadotropin production in rat hypothalamic-pituitary-gonadal axis, the present study was designed to investigate the circulating concentrations of phoenixin-14 and their associations with the concentrations of sex hormones including luteinizing hormone (LH), follicular stimulating hormone (FSH), estradiol (E2), progesterone (P4) and total testosterone (TT) in PCOS patients...

Adiponectin regulates glucose and lipid metabolism, acting against atherosclerosis and metabolic syndrome. Accumulating evidences suggest that adiponectin acts on the brain including the arcuate nucleus of hypothalamus (ARC). The ARC contains orexigenic neuropeptide Y (NPY)/agouti related peptide (AgRP) neurons and anorexigenic proopiomelanocortin (POMC) neurons, the first order neurons for feeding regulation. We recently reported that intracerebroventricular injection of adiponectin at low glucose level suppressed food intake, while at elevated glucose level it promoted food intake, exhibiting glucose-dependent reciprocal effects...

Although it has been proposed that the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis may act as a possible pathway linking early life stress to psychosis, this relationship has not yet been fully confirmed. This study aimed to investigate the relationship between childhood adversity (CA), cortisol levels, and psychosis. Eighty-five patients with psychosis and 170 control subjects were enrolled in the study. CA was evaluated using the Florence Psychiatric Interview, and Childhood Experience of Care and Abuse Questionnaire...

The discovery of intrinsic epileptogenicity of the hypothalamic hamartoma (HH) marked a new area in understanding the associated clinical syndrome, often manifesting as progressive epileptic encephalopathy. However, therapeutic procedures targeting the HH proved to be inefficient to cure seizures in up to 50% of cases, whereas in cases with partial improvement, the electroclinical patterns of persisting seizures suggest an involvement of distant cortical regions. The concept of kindling-like secondary epileptogenesis has been suggested as a possible underlying mechanism...

Gelastic seizures, usually with onset in early infancy, are the hallmark manifestation of hypothalamic hamartoma. This seizure type is directly generated by hamartoma itself, intrinsically epileptogenic because of its anatomofunctional organization. Other types of seizures, focal or generalized, may appear during the evolution, probably resulting from mechanisms of secondary epileptogenesis. Nevertheless, the clinical expression and the severity of the syndrome, ranging from a focal drug-resistant epilepsy to a catastrophic generalized encephalopathy with severe cognitive and behavioral impairments, depends on the size and the site of attachment of the hamartoma...

Maternal uniparental disomy of chromosome 14 (upd(14)mat) or Temple syndrome is an imprinting disorder associated with a relatively mild phenotype. The absence of specific congenital malformations makes this condition underdiagnosed in clinical practice. A boy with a de novo robertsonian translocation 45,XY,rob(13;14)(q10;q10) is reported; a CGH/SNP array showed a loss of heterozygosity in 14q11.2q13.1. The final diagnosis of upd(14)mat was made by microsatellite analysis, which showed a combination of heterodisomy and isodisomy for different regions of chromosome 14...

Sleep plays a vital role in brain function and systemic physiology across many body systems. Problems with sleep are widely prevalent and include deficits in quantity and quality of sleep; sleep problems that impact the continuity of sleep are collectively referred to as sleep disruptions. Numerous factors contribute to sleep disruption, ranging from lifestyle and environmental factors to sleep disorders and other medical conditions. Sleep disruptions have substantial adverse short- and long-term health consequences...

This review discusses the current state of our understanding regarding the genetic basis of the most important reproductive disorders in women. For clarity, these disorders have been divided into eugonadal and hypogonadal types. Hypogonadal disorders have been further subdivided according to serum gonadotropin levels. Our review focuses on historical and recent data regarding the genetics of the hypothalamic-pituitary-gonadal axis dysfunction, as well as the development and etiology of eugonadal disorders including leiomyomata, endometriosis, spontaneous ovarian hyperstimulation syndrome, polycystic ovarian syndrome, mullerian aplasia, and steroid hormone resistance syndromes...

Korsakoff syndrome is a chronic memory disorder caused by a severe deficiency of thiamine that is most commonly observed in alcoholics. However, some have proposed that focal structural lesions disrupting memory circuits-in particular, the mammillary bodies, the mammillothalamic tract, and the anterior thalamus-can give rise to this amnestic syndrome. Here, the authors present 4 patients with reversible Korsakoff syndromes caused by suprasellar retrochiasmatic lesions compressing the mammillary bodies and adjacent caudal hypothalamic structures...

Cannabinoid hyperemesis syndrome (CHS), a variant of cyclic vomiting syndrome, is an enigmatic and challenging clinical disorder. As cannabis legalization, use, and potency has increased worldwide over the past decade, so has the prevalence of CHS. These patients often require acute care and inpatient treatment for refractory emesis, electrolyte derangement, dehydration, acute renal failure, and injury to the upper gastrointestinal tract. Routinely-prescribed antiemetics are frequently associated with treatment failure in CHS, necessitating use of sedating agents such as benzodiazepines and antipsychotics...

Impaired sleep and alertness affect the majority of Parkinson's disease (PD) patients, negatively impacting safety and quality of life. The etiology of impaired sleep-wake cycle in PD is multifactorial and encompasses medication side effects, nocturnal PD motor symptoms, and presence of co-existent sleep and neuropsychiatric disorders. The primary neurodegenerative process of PD involves brain regions that regulate the sleep-wake cycle, such as brainstem and hypothalamic nuclei. Sleep disorders in PD include insomnia, REM sleep behavior disorder (RBD), sleep disordered breathing (SDB), restless legs syndrome (RLS), and circadian disruption...

Due to the clinical picture and also based on early imaging data (Weiller et al. Nat Med 1:658-660, 1995), the brainstem and midbrain structures have been intensely discussed as possible driving or generating structures in migraine. The fact that the brainstem activation persisted after treatment makes it unlikely that this activation was only due to increased activity of the endogenous anti-nociceptive system. It was consequently (and somewhat simplifying) coined the "migraine generator". Since then several studies have focussed on this region when investigating episodic, but also chronic migraine...

Glucocorticoids are potent modulators of metabolic and behavioral function. Their role as mediators in the "stress response" is well known, but arguably their primary physiological function is in the regulation of cellular and organismal metabolism. Disruption of normal glucocorticoid function is linked to metabolic disease, such as Cushing's syndrome. Glucocorticoids are also elevated in many forms of obesity, suggesting that there are bidirectional effects of these potent hormones on metabolism and metabolic function...

Approximately 60% of all patients with epilepsy suffer from focal epilepsy syndromes. In approximately 15% of these patients, the seizures are not adequately controlled with anticonvulsive drugs, and such patients are potential candidates for surgical treatment and majority are children. Epilepsy surgery in children, who have been carefully chosen, can result in either seizure freedom or a marked (>90%) reduction in seizures in approximately two-third of children with intractable seizures. In the multimodality presurgical evaluation approach, sufficient concordance should be established among various independent investigations, thus identifying the location and extent of the epileptogenic zone with a high degree of confidence...
