Obsessive-compulsive disorder (OCD) is a frequent and severe disease, potentially inducing a major impairment for the patient and burden for their family. Recent research in psychiatry and neuroscience have led to better comprehension of the disease's mechanisms and helped to improve its treatment. However, a large proportion of patients have refractory symptoms, including for traditional cognitive and behavioral therapy by exposure and response prevention (ERP), leading clinicians to look for new treatments...

Invasive and non-invasive vagus nerve stimulation (VNS) is a promising add-on treatment for treatment-refractory depression, but is also increasingly evaluated for its application in other psychiatric disorders, such as dementia, schizophrenia, somatoform disorder, and others. We performed a systematic review aiming to give a detailed overview of the available evidence of the efficacy of VNS for the treatment of psychiatric disorders. Data derived from animal models, experimental trials without health-related outcomes, case reports, single-session studies, and reviews were excluded...

The vagus nerve is a major component of the autonomic nervous system and plays a critical role in many body functions including for example, speech, swallowing, heart rate and respiratory control, gastric secretion, and intestinal motility. Vagus nerve stimulation (VNS) refers to any technique that stimulates the vagus nerve, with electrical stimulation being the most important. Implantable devices for VNS are approved therapy for refractory epilepsy and for treatment-resistant depression. In the case of heart disease applications, implantable VNS has been shown to be beneficial for treating heart failure in both preclinical and clinical studies...

Body dysmorphic disorder is a common, often disabling condition, and is frequently comorbid with major depressive disorder. Selective serotonin reuptake inhibitors constitute first line set of somatic interventions but the management of refractory patients remains challenging. Electroconvulsive therapy, an often highly beneficial treatment for medication resistant-depression, is not considered an effective therapeutic alternative for treatment refractory body dysmorphic disorder. Here we present a 50-year-old woman with body dysmorphic disorder and comorbid major depressive disorder who remained incapacitated and suicidal despite several trials with selective serotonin reuptake inhibitors and antipsychotic medication...

Ketamine, at sub-anesthetic doses, is reported to rapidly decrease depression symptoms in patients with treatment-resistant major depressive disorder (MDD). Many patients do not respond to currently available antidepressants, (for example, serotonin reuptake inhibitors), making ketamine and its enantiomer, esketamine, potentially attractive options for treatment-resistant MDD. Although mechanisms by which ketamine/esketamine may produce antidepressant effects have been hypothesized on the basis of preclinical data, the neurobiological correlates of the rapid therapeutic response observed in patients receiving treatment have not been established...

Surgery is an established and increasingly utilized treatment option in medically refractory temporal lobe epilepsy. Many psychiatric problems are known to complicate in the postoperative period. Most studies have a follow-up period of less than 24 months. We report the cases of three patients who developed severe psychiatric problems in the late postoperative period after successful temporal lobectomy for refractory epilepsy - Psychosis, major depression with psychosis, and severe anxiety disorder, respectively...

OBJECTIVE: Treatment-refractory depression is a devastating condition with significant morbidity, mortality, and societal cost. At least 15% of cases of major depressive disorder remain refractory to treatment. The authors previously identified a young adult with treatment-refractory depression and multiple suicide attempts with an associated severe deficiency of CSF tetrahydrobiopterin, a critical cofactor for monoamine neurotransmitter synthesis. Treatment with sapropterin, a tetrahydrobiopterin analogue, led to dramatic and long-lasting remission of depression...

Treatment-resistant depression (TRD) is a disabling disorder that can interfere with a patient's capacity to understand and participate in medical care and thus negatively impact individual morbidity and mortality. Hospitalised patients with TRD may require rapid alleviation of severe symptomatology, particularly when suicidal or if unable to participate in care decisions. Ketamine is well known for its anaesthetic effects and its use as a 'street' drug; however, its action as an N-methyl-D-aspartate receptor antagonist makes ketamine a potential therapy for TRD...

Following administration at subanesthetic doses, (R,S)-ketamine (ketamine) induces rapid and robust relief from symptoms of depression in treatment-refractory depressed patients. Previous studies suggest that ketamine's antidepressant properties involve enhancement of dopamine (DA) neurotransmission. Ketamine is rapidly metabolized to (2S,6S)- and (2R,6R)-hydroxynorketamine (HNK), which have antidepressant actions independent of N-methyl-d-aspartate glutamate receptor inhibition. These antidepressant actions of (2S,6S;2R,6R)-HNK, or other metabolites, as well as ketamine's side effects, including abuse potential, may be related to direct effects on components of the dopaminergic (DAergic) system...

In the majority of cases of bipolar disorder, manic episodes are usually brief and typically responsive to currently available psychopharmacological agents. In contrast, depressive manifestations are more prevalent and persistent, and can present as major depressive/mixed episodes or residual interepisode symptoms. The depressive phase is often associated with other neuropsychiatric conditions, such as anxiety spectrum disorders, substance use disorders, stressor-related disorders, and eating disorders. It is viewed as a systemic disease with associated ailments such as metabolic syndrome, diabetes mellitus, and cardiovascular disease...

Deep brain stimulation (DBS) is a promising putative modality for the treatment of refractory psychiatric disorders such as major depression and obsessive-compulsive disorder (OCD). Several targets have been posited; however, a clear consensus on differential efficacy and possible modes of action remain unclear. DBS to the supero-lateral branch of the medial forebrain bundle (slMFB) has recently been introduced for major depression (MD). Due to our experience with slMFB stimulation for MD, and because OCD might be related to similar dysfunctions of the reward system, treatment with slMFB DBS seams meaningful...

UNLABELLED: Deep Transcranial Magnetic Stimulation (dTMS) is the next generation of technology used to treat Major Depressive Disorder (MDD). dTMS has been proven to be a safe and effective treatment modality for MDD and may have secondary benefits in patients with chronic low back pain by reducing pain related morbidity. We are presenting two case studies with MDD and chronic low back pain to demonstrate the effectiveness of both the antidepressant and analgesic effects of dTMS. BACKGROUND: Transcranial Magnetic Stimulation (rTMS) utilizes MRI-strength magnetic pulses outside the cranium to stimulate the brain to a depth of approximately 1 cm...

BACKGROUND: The phosphatidylinositol-3 kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway is dysregulated in patients with metastatic renal cell carcinoma (mRCC). Buparlisib is a pan-PI3K inhibitor with activity in advanced solid tumors. The primary objective of the current study was to determine the maximum tolerated dose (MTD) and dose-limiting toxicities of buparlisib and bevacizumab in patients with mRCC. Secondary objectives included efficacy, biomarker discovery, and additional toxicity...

Bipolar disorder is characterized by exacerbations of opposite mood polarity, ranging from manic to major depressive episodes. In the current nosological system of the Diagnostic and Statistical Manual - 5(th) edition (DSM-5), it is conceptualized as a spectrum disorder consisting of bipolar disorder type I, bipolar disorder type II, cyclothymic disorder, and bipolar disorder not otherwise specified. Treatment of all phases of this disorder is primarily with mood stabilizers, but many patients either show resistance to the conventional mood stabilizing medications or are intolerant to their side-effects...

The most widely used target for repetitive transcranial magnetic stimulation (rTMS) in treatment-resistant depression (TRD) is the dorsolateral prefrontal cortex (DLPFC). Despite convergent evidence that the dorsomedial prefrontal cortex (DMPFC) may be a promising alternative target for rTMS in TRD, its cognitive safety profile has not previously been assessed. Here, we applied 20 sessions of rTMS to the DMPFC in 21 TRD patients. Before and after treatment, a battery of neuropsychological tasks was administered to evaluate changes in cognition across three general cognitive domains: learning and memory, attention and processing speed, and cognitive flexibility...

PURPOSE: Major depression and related mood disorders are the most common long-term outcomes associated with traumatic brain injury (TBI). Given the potentially debilitating consequences of depression, and the fact that TBI patients are frequently refractory to antidepressant drugs, new therapies are clearly needed. We hypothesized that human bone marrow-derived mesenchymal stem cells (hMSC), delivered intravenously, can effectively treat TBI-induced depression and other behavioral deficits associated with TBI...

Free jejunal transfer is the main technique used for reconstructing a circumferential defect caused by total pharyngo-laryngo-cervical-esophagectomy in certain cancer cases. We report a rare case of severe late-onset dysphagia caused by autonomous spastic peristalsis, which led to complete obstruction of the free jejunal route. A 70-year-old man underwent treatment for hypopharyngeal cancer involving total pharyngolaryngectomy with free jejunal transfer. After uneventful peri- and postoperative recovery, he developed sudden-onset severe dysphagia 22 months later...

Multiple factors such as genetic and extraneous causes (drugs, toxins, adverse psychological events) contribute to neuro-psychiatric conditions. In a subgroup of these disorders, systemic folate deficiency has been associated with macrocytic anemia and neuropsychiatric phenotypes. In some of these, despite normal systemic levels, folate transport to the brain is impaired in the so-called cerebral folate deficiency (CFD) syndromes presenting as developmental and psychiatric disorders. These include infantile-onset CFD syndrome, infantile autism with or without neurologic deficits, a spastic-ataxic syndrome and intractable epilepsy in young children expanding to refractory schizophrenia in adolescents, and finally treatment-resistant major depression in adults...
