SMALL-BOWEL CAPSULE ENDOSCOPY (SBCE): 1: ESGE recommends that prior to SBCE patients ingest a purgative (2 L of polyethylene glycol [PEG]) for better visualization.Strong recommendation, high quality evidence.However, the optimal timing for taking purgatives is yet to be established. 2: ESGE recommends that SBCE should be performed as an outpatient procedure if possible, since completion rates are higher in outpatients than in inpatients.Strong recommendation, moderate quality evidence...

For some patients, coma is followed by a state of unresponsiveness, while other patients develop signs of awareness. In practice, detecting signs of awareness may be hindered by possible impairments in the patient's motoric, sensory, or cognitive abilities, resulting in a substantial proportion of misdiagnosed disorders of consciousness. Task-free paradigms that are independent of the patient's sensorimotor and neurocognitive abilities may offer a solution to this challenge. A limitation of previous research is that the large majority of studies on the pathophysiological processes underlying disorders of consciousness have been conducted using cross-sectional designs...

This article describes the conclusions of an investigation done with 120 Spanish patients: the finding of a new psychopathological profile within a subgroup of patients suffering from schizophrenia. The patients were evaluated through different questionnaires about sociodemographic data, traumatic events, the severity index (both clinical and psychopathological), self-esteem and consciousness of the illness. From the scores obtained on a scale of dissociative experiences, they were classified into two groups: high dissociative symptomatology or HD, and low dissociative symptomatology or LD...

The word hysteria originated in the Corpus Hippocraticum (c420 BCE) as a natural explanation for a variety of diseases in women linked in the Greco-Roman mind to an animate or inanimate womb, but which in the last five centuries has evolved to describe an elusive disorder of brain ± mind in men and women, currently referred to by neurologists as "functional neurological disorder". The Babylonians, Assyrians and Egyptians had no knowledge of brain or psychological function. Babylonian and Assyrian descriptions of disease and behaviour include only rare examples suggestive of modern hysteria...

Despite intensive research, a precise cause of schizophrenic and schizoaffective disorders has not yet been identified. Therefore, psychiatric diagnoses are still made based on clinical ICD-10/DSM‑5 criteria and not on any objective markers; however, various causes or pathophysiological processes may ultimately lead to similar symptoms. An important task for the future of psychiatry is to identify disease subtypes with a distinct pathophysiology to develop more specific and causally acting therapies. A new diagnostic entity has become established in clinical neurology and psychiatry in recent years: autoimmune encephalitis with psychotic symptoms caused by specific antineuronal antibodies has been identified as a rare but potentially treatable cause of psychotic disorders; however, these inflammatory brain diseases are not reliably detected by routine psychiatric diagnostics...

The neuronal control of the immune system is fundamental to the development of new therapeutic strategies for inflammatory disorders. Recent studies reported that afferent vagal stimulation attenuates peripheral inflammation by activating specific sympathetic central and peripheral networks, but only few subcortical brain areas were investigated. In the present study, we report that afferent vagal stimulation also activates specific cortical areas, as the parietal and cingulate cortex. Since these cortical structures innervate sympathetic-related areas, we investigate whether electrical stimulation of parietal cortex can attenuate knee joint inflammation in non-anesthetized rats...

Disorder of consciousness (DOC) can be either an acute and reversible condition or a chronic condition, including vegetative state or minimally conscious state. Herein, we describe a patient who has unexpectedly recovered consciousness after being in a misdiagnosed vegetative state for a long period. A 63-year-old woman was admitted to our rehabilitation center in vegetative state (Coma Recovery Scale-Revised score, 6) and treated with a standard rehabilitation program, including physical therapy and multisensory stimulation, besides psychoactive drugs...

Research in clinical and human neuroscience indicates that important brain mechanisms of self-consciousness are based on the integration of multisensory bodily signals (i.e., bodily self-consciousness: BSC), including signals coming from outside our body (i.e., exteroceptive signals, such as tactile, auditory, and visual information) and the inside of our body (i.e., interoceptive signals). In this chapter, we discuss selected behavioral and neuroimaging studies about how multisensory integration generates and modulates BSC in humans, with particular relevance to parietal mechanisms...

OBJECTIVE: Posttraumatic stress disorder and childhood trauma frequently co-occur. Both are associated with abnormal neural responses to salient emotion stimuli. As childhood trauma is a risk factor for posttraumatic stress disorder, differentiating between their neurophysiological effects is necessary to elucidate the neural pathways by which childhood trauma exposure contributes to increased posttraumatic stress disorder risks. METHODS: Face-specific N170 evoked response potentials for backward-masked (non-conscious) and conscious threat (fear, angry) and non-threat (happy) faces were measured in 77 adults (18-64 years old, 64% women, 78% right-handed) symptomatic for posttraumatic stress disorder...

OBJECTIVE: Objectification theory posits that self-objectification increases risk for disordered eating. METHOD: The current study sought to examine the relationship between self-objectification and disordered eating using meta-analytic techniques. RESULTS: Data from 53 cross-sectional studies (73 effect sizes) revealed a significant moderate positive overall effect (r = .39), which was moderated by gender, ethnicity, sexual orientation, and measurement of self-objectification...

After a hiatus of some 40 years, clinical research has resumed on the use of classic hallucinogens to treat addiction. Following completion of a small open-label feasibility study, we are currently conducting a double-blind placebo-controlled clinical trial of psilocybin-assisted treatment of alcohol use disorder. Although treatment effects cannot be analyzed until the study is complete, descriptive case studies provide a useful window into the therapeutic process of psychedelic-assisted treatment of addiction...

Can "hardwired" physiological fear responses (e.g., for spiders and snakes) be reprogramed unconsciously in the human brain? Currently, exposure therapy is among the most effective treatments for anxiety disorders, but this intervention is subjectively aversive to patients, causing many to drop out of treatment prematurely. Here we introduce a method to bypass the subjective unpleasantness in conscious exposure, by directly pairing monetary reward with unconscious occurrences of decoded representations of naturally feared animals in the brain...

Mild traumatic brain injury (mTBI) is highly prevalent, with an estimated occurrence in the United States of more than 1.3 million per year. While one consequence of mTBI is impulsive aggressive behavior, very few studies have examined the relationship between history of mTBI and aggressive behavior in impulsively aggressive individuals. The authors examined the relationship between history of mTBI in a healthy control group (HC; N=453), a control group with psychiatric disorders (PC; N=486), and individuals with intermittent explosive disorder (IED; N=695), a disorder of primary impulsive aggression...

RATIONALE: Thyroid storm is a rare complication during caesarean section of patients with hyperthyroidism. It occurs abruptly, with a high mortality rate if not recognized immediately and aggressively treated. Herein, we reported a case of impending thyroid storm during a caesarean section. PATIENT CONCERNS: A healthy 23-year-old woman with undiagnosed hyperthyroidism underwent an emergency caesarean section under general anesthesia. After tracheal extubation, the patient exhibited abnormal tachycardia, agitation, sweating, and hyperpyrexia...

Visual pursuit (VP) and visual fixation (VF) have been recognized as the first signs of emerging consciousness and, therefore, are considered indicative of the minimally conscious state (MCS). However, debate exists about their status as they are considered either conscious reactions or reflexes. The aim of this study is to review the evidence of the definition, operationalization, and assessment of VP and VF in unconscious patients. PubMed and EMBASE were searched for relevant papers between May 26, 1994 and October 1, 2016...

BACKGROUND: Health outcomes among men are markedly poorer than women. Testicular disorders can be life-threatening if left untreated. Few studies promoting awareness of testicular disorders have been underpinned by theory. Theory-based interventions are more likely to achieve positive health outcomes than interventions that lack a theoretical foundation. OBJECTIVES: The purpose of the study is to present a theory-focused analysis of the preconscious awareness to action framework (PAAF), developed to enhance testicular awareness and help-seeking intentions and behaviors among men...

Prediction of the functional recovery in patients with disorders of consciousness (DOC) is still complex because of the different numbers of variables that influence the possibility of observing changes in clinical outcome. The aim of the present study is to identify the best set of predictors of the change in DOC diagnosis among different pharmacotherapy and nonpharmacotherapy indicators. This study analyzed data collected in a longitudinal, two-evaluation, multicenter project conducted in 90 centers. We analyzed the predictor effects of physical and cognitive treatments, duration of disease, etiology, age, and sex (nonpharmacological treatments) as well as the use of antiparkinson, psycholeptic, psychoanaleptic, and muscle-relaxant drugs (pharmacological variables)...

The current considerations about completed suicides and suicide attempts in different cultures call the attention of professionals to this serious public health problem. Integrative approaches have shown that the confluence of multiple biological and social factors modulate various psychopathologies and dysfunctional behaviors, such as suicidal behavior. Considering the level of intermediate analysis, personality traits and cognitive functioning are also of great importance for understanding the suicide phenomenon...

OBJECTIVES: Patients with chronic disorders of consciousness (DOC) may show alterations of autonomic function; however, in this clinical population, no data are available on the specific effects of nociceptive stimuli on cardiac autonomic control. Thus, we aimed at investigating the effects of a noxious stimulation on heart rate variability (HRV) in a population of patients with chronic DOC, taking into account different states of consciousness (vegetative state/unresponsive wakefulness syndrome, VS/UWS and minimally conscious state, MCS)...

Case reports of the abrupt recovery of hysterical disorders during World War I (1914-18), though undoubtedly subject to publication bias, raise both aetiological and treatment issues regarding pseudo-neurological conversion symptoms. Published clinical anecdotes report circumstantial, psychotherapeutic, hypnotic, persuasive (and coercive) methods seemingly inducing recovery, and also responses to fright and alterations of consciousness. The ethics of modern medical practice would not allow many of these techniques, which were reported to be effective, even in the chronic cases...
