Combined Oxytocin and Cognitive Behavioral Social Skills Training for Social Function in People With Schizophrenia.

BACKGROUND: A significant proportion of people with schizophrenia are characterized by impaired ability to socially engage with others. The development of effective interventions for social functioning remains a central therapeutic challenge. Cognitive-behavioral social skills training (CBSST) has been found to improve social functioning in schizophrenia, but with only medium effect sizes. Intranasal oxytocin also has prosocial effects, but also only with modest effect sizes. This study assessed whether the addition of intranasal oxytocin to CBSST can strengthen their impact on social function. METHODS: Participants (N = 62) with schizophrenia or schizoaffective disorder entered a 24-week, double-blind, placebo-controlled, randomized clinical trial with a 3-month follow-up evaluation at 2 sites: Maryland and San Diego. Participants were randomized to either intranasal oxytocin 36 IU (3 sprays) twice a day (n = 31) or intranasal placebo-oxytocin (3 sprays) twice a day (n = 31). All participants received CBSST plus a social cognition skills training module (48 total sessions). RESULTS: There were no significant treatment group differences in social functioning, positive symptoms, negative symptoms, defeatist beliefs, or asocial beliefs. The interpretation of treatment effects was complicated by site effects, whereby participants in San Diego began the trial with greater severity of impairments and subsequently showed greater improvements compared with participants in Maryland. CONCLUSIONS: The results did not support the utility of add-on intranasal oxytocin to psychosocial rehabilitation interventions like CBSST for improvement in social function (ClinicalTrials.gov trial number: NCT01752712).

Bilateral anterior capsulotomy enhances medication compliance in patients with epilepsy and psychiatric comorbidities.

OBJECTIVES: Patients with epilepsy and refractory comorbid psychiatric disorders often experience functional impairments and a lower quality of life as well as showing a lack of compliance with anti-epileptic medication regimens. We reasoned that widespread clinical benefits could be gained if the psychiatric comorbidities among these patients were reduced. In this study, we assessed the utility of anterior capsulotomy in managing medication-refractory comorbid psychotic symptoms and aggression in patients with epilepsy. METHODS: In this retrospective case series, we evaluated the clinical outcomes of 13 epilepsy patients with severe psychiatric comorbidities who had received bilateral anterior capsulotomy. Clinical outcome assessments were performed at 1 week, 6 months, 1 year, and several years after surgery focusing on: (a) severity of psychotic symptoms, as assessed by the 18-item Brief Psychiatric Rating Scale and the Positive and Negative Syndrome Scale; (b) severity of impulsivity and aggression, measured by the Barratt Impulsiveness Scale-11 and the Buss-Perry Aggression Scale; and (c) social function and quality of life, assessed by the Social Disability Screening Scale and the Quality of Life in Epilepsy. RESULTS: After anterior capsulotomy, patients displayed significant improvements of psychotic symptoms, as well as of impulsivity and aggression, along with improvements of social function and quality of life. The clinical benefits to patients were evident within 6 months after surgery and remained stable or continued to improve at a much slower rate thereafter. Furthermore, after anterior capsulotomy all patients complied with epilepsy interventions that they did not comply with prior to surgery. No significant side effects or complications occurred during the study. CONCLUSION: Anterior capsulotomy seems to be a safe and effective treatment for epilepsy patients with otherwise intractable comorbid psychotic symptoms and aggression. Moreover, this neurosurgical treatment may improve the patients' social function, quality of life, and compliance with anti-epilepsy medication regimens.

Cases of remission of psychosis following resection of pheochromocytoma or paraganglioma.

The author previously proposed that schizophrenia has similar cytokine expression compared to melanoma, a neural crest cell tumor. One possible tumor model of schizophrenia includes anti-NMDA receptor encephalitis, a paraneoplastic syndrome. While examining the possible relationship of neural crest cell tumors to schizophrenia, the author found several case reports of psychosis resulting from pheochromocytomas and paragangliomas, types of neural crest cell tumors that secrete catecholamines. In most cases, surgical resection of the tumors resulted in remission of psychotic symptoms, and some remissions were associated with reduced levels of peripheral catecholamine levels. These reports suggest, first, that the differential diagnosis of psychosis with autonomic instability should include these tumors. Second, the cases raise a theoretical question as to how these tumors might cause psychosis. On one hand, the elevated peripheral catecholamines caused by these tumors generally agree with aspects of the dopamine hypothesis of schizophrenia although the mechanism of how peripheral dopamine would cause psychosis is unknown. On the other hand, these tumors could possibly secrete an unidentified antibody to a receptor similar to what is observed in anti-NMDA receptor encephalitis.

Multidisciplinary approach and anesthetic management of a surgical cancer patient with methylene tetrahydrofolate reductase deficiency: a case report and review of the literature.

INTRODUCTION: Hyperhomocysteinemia is a known risk factor for myocardial infarction, stroke, peripheral vascular disease, and thrombosis. Elevated plasma homocysteine levels have been demonstrated in patients with recurrent episodes or a single episode of thrombosis. Here we describe the development of cardiovascular disease as a complication of a surgical intervention in a patient with colorectal cancer and hyperhomocysteinemia. CASE PRESENTATION: A 65-year-old Caucasian man complained of pain and constipation, attributed to previously diagnosed adenocarcinoma (stage IIB) of the hepatic flexure. An anamnestic investigation showed that he had undergone two surgical interventions. During both, he suffered thrombotic postoperative complications, a deep vein thrombosis of the upper extremity after the first operation and retinal vein occlusion after the second. He was diagnosed with hyperhomocysteinemia associated with a homozygous C677T mutation of the gene encoding the enzyme methylenetetrahydrofolate reductase. Our patient was initially treated with folic acid and high-dose B vitamins. On day 7 he underwent a right hemicolectomy. Anesthesia was performed with sevoflurane in 40% O2 and without the use of nitrous oxide. Postoperatively, our patient remained on folic acid and B vitamins and was without immediate or subsequent complications. CONCLUSIONS: Neoplastic disease and related surgery followed by the administration of chemotherapeutic drugs alter the hemostatic balance in cancer patients. Those suspected of also having a thrombophilic disease require a thorough laboratory diagnostic workup, including a molecular analysis aimed at identifying the genetic mutation responsible for the hyperhomocysteinemia, as indicated. The case described in this report highlights the importance of a multidisciplinary approach that includes expertise in peri-operative anesthesia, surgery, oncology, and hematology.

Safety of video-EEG monitoring and surgical outcome in patients with mesial temporal sclerosis and psychosis of epilepsy.

PURPOSE: Cortico-amygdalohippocampectomy (CAH) has become an important treatment option for patients with refractory temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS); it has resulted in a 60-70% seizure remission rate and significant quality of life (QOL) improvements. Video-electroencephalography (VEEG) monitoring has been widely used in epilepsy centers for pre-surgical evaluation. A major concern in epilepsy surgery is whether to consider CAH treatment in patients with psychosis of epilepsy (POE). This study analyzed the safety and adverse events (AEs) of VEEG monitoring and the post-surgical outcomes of patients with refractory TLE-MTS and POE who underwent CAH. METHOD: Clinical, sociodemographic and VEEG data from 18 patients with TLE-MTS and POE were analyzed. Psychiatric evaluations were performed using DSM-IV and ILAE criteria. The seizure outcome was evaluated using Engel's criteria. RESULTS: Two patients (11.2%) presented AEs that did not result in increased lengths of hospitalization. Of the 10 patients (55.5%) who underwent CAH, 6 (60%) became free of disabling seizures (Engel I). The psychiatric and QOL evaluations revealed improvements of psychotic symptoms (p=0.01) and in Physical Health (p=0.01) following surgery. CONCLUSION: These data reinforce that VEEG monitoring is a safe method to evaluate patients with refractory TLE-MTS and POE in epilepsy centers.

One-year postsurgical follow-up of 12 subjects with epilepsy and interictal psychosis.

We describe the 1-year follow-up after epilepsy surgery of 12 patients with chronic interictal psychosis and medically intractable epilepsy. The 12 cases described were part of a sample of 350 subjects who concluded a 1-year psychiatric follow-up from a total of 504 subjects operated on for medically intractable epilepsy between 2002 and 2009. Outcome was Engel class IA for five of these patients, IB for one, ID for one, IIB for one, IIIA for three, and IVA for one. Four patients had a worsening of psychotic symptoms at 6 months, but showed improvement after 1 year; two subjects had a worsening of psychotic symptoms at both 6 months and 1 year. Despite the severity of symptoms, compliance with preoperative assessment, surgical programs, and follow-up was satisfactory.

Body dysmorphic disorder and other psychiatric morbidity in aesthetic rhinoplasty candidates.

BACKGROUND: Body dysmorphic disorder (BDD) is a psychiatric disorder characterised by the patient's preoccupation with an imagined defect in his or her physical appearance. Subjects with BDD often seek cosmetic surgery; however, the outcome of surgery is usually not satisfactory. The aim of current study was to investigate the prevalence of BDD among the patients seeking cosmetic surgery. METHOD: In a cross-sectional study, 306 patients referred to cosmetic surgery clinics were recruited. Two psychiatrists detected BDD by interviewing the patients using Diagnostic and Statistical Manual of Mental Disorders fourth edition Text Revision (DSM IV-TR) criteria. Data analysis was done in Statistical Package for Social Sciences (SPSS) using the t-test and the Mann-Whitney test for numeral variables and the chi-square and Fisher's exact tests for nominal variables. RESULTS: Data analysis of demographics showed that 80% of patients were female. Analysis on disease-related variables showed that 126 (41%) of patients had an associated psychiatric disorder. Moreover, 75 patients (24.5%) fulfilled the DSM IV criteria for BDD. CONCLUSION: Findings from this study support earlier studies, which found that BDD is a relatively common disorder among individuals seeking aesthetic surgery, in particular in rhinoplasty patients. Preoperative psychiatry assessment recommends avoiding subsequent risk for both patients and surgeons.

The effect of surgery on the postictal state.

The effect of surgery on the postictal state has not been studied in a systematic fashion. There is limited literature looking at the effect on postictal psychosis. The effect of surgery on this phenomenon has been varied with post ictal psychosis occurring post surgery when it has not occurred prior to surgery as well as resolution after surgery. Case reports of post ictal Kluver Bucy Syndrome and Capgas Syndrome have been reported after resective epilepsy surgery as well.

Remission of drug-resistant epileptic psychosis following left selective amygdalohippocampectomy.

We describe two female patients with drug-resistant mesial temporal lobe epilepsy and chronic drug-resistant psychosis. In both patients, MRI scans revealed left mesial temporal sclerosis. After clinical assessment, ictal video/EEG monitoring, and a neuropsychological evaluation including Wada testing, the patients underwent selective left amygdalohippocampectomy. Since the operation, the two patients have remained free of seizures for 17 and 15 months. During the same period, both patients have sustained a full remission of the psychosis.

Deep brain stimulation in movement and psychiatric disorders.

Deep brain stimulation (DBS) is the most focal and invasive of the electromagnetic brain stimulation therapies. A subcutaneous pulse generator provides continuous stimulation of circumscribed brain tissue via a multicontact microelectrode that terminates within its target. The result is an adjustable, reversible, and specific therapy. Despite limited understanding of its mechanisms of action, DBS efficacy has been established in several movement disorders, and promising reports have emerged for Tourette syndrome, obsessive-compulsive disorder, and major depression. Deep brain stimulation may prove to be a reasonable option for severely ill and treatment-resistant patients who otherwise have limited therapeutic options and a poor prognosis.

Psychosis or temporal lobotomy: SPECT findings in a paraplegic patient with chronic mental illness.

OBJECTIVE: To ascertain if single proton emission computerized tomography (SPECT) imaging involving a patient with a history of head trauma, paraplegia, and chronic mental illness, would provide useful information regarding diagnosis and treatment. METHOD: A case report. RESULTS: SPECT data indicated a convexity of the temporal lobe; it was significantly crumpled inward in the location of the traumatic blow suffered 18 years earlier. The center of hypoperfusion suggested a complete disruption of connections between the temporal lobe and Broca's area, and a practically ablated left temporal area. CONCLUSION: The patient was reclassified with an organic psychosis and as an individual who might benefit more from medications to treat temporal lobe irritability rather than antipsychotic medications. Despite these findings and recommendations, psychiatric personnel discharged the patient without implementation. He is currently in critical condition following a suicide attempt.

Cingulotomy for psychiatric disease: microelectrode guidance, a callosal reference system for documenting lesion location, and clinical results.

OBJECTIVE: To evaluate magnetic resonance imaging (MRI)- and microelectrode recording-guided cingulotomy for patients with psychiatric disorders and to develop a new method of mapping lesion location in anterior cingulate cortex that takes into account the significant interindividual variability in callosal morphometry. METHODS: MRI and microelectrode recording were used to guide placement of radiofrequency lesions in patients with obsessive-compulsive disorder (n = 21) or affective disorders (n = 5). Postoperative improvement was evaluated with the Yale-Brown Obsessive-Compulsive Scale in 15 of the 21 obsessive-compulsive disorder patients studied. From the postoperative MRI scans, we developed a coordinate system for position in the anterior cingulate cortex. The callosal line passes from the most anterior point of the corpus callosum (c = 0) to the most posterior (c = 100). We reconstructed the lesions onto a sagittal map from the Talairach and Tournoux atlas using the distance along the callosal line and the distance above the upper surface of the corpus callosum. RESULTS: The location of neuronal activity distinguished gray and white matter and was useful in delineating the upper and lower cortical banks of the cingulate gyrus, the cingulate bundle, and the corpus callosum. This information was used to place the lesions. Lesions typically were 6 to 8 mm in diameter on T2-weighted MRI scans. The inferior margins were along the corpus callosum from c = 16 to c = 38. Four of 15 patients with obsessive-compulsive disorder had a documented decrease of more than 35% on the Yale-Brown Obsessive-Compulsive Scale, but only one patient had a sustained benefit for more than 1 year. CONCLUSION: Microelectrode recording is useful for lesion placement. Our system for reporting location in anterior cingulate cortex normalizes for differences in callosal morphometry. These techniques may aid future study.

Severe myopathy and psychosis in a patient with Cushing's disease macroadenoma.

Cushing's disease is most commonly caused by a corticotrope adenoma of the pituitary. Between 50 and 70% of patients with spontaneous hypercortisolism have ACTH-producing pituitary adenomas. The tumors are usually microadenomas with approximately 20% of patients with the disease showing no evidence of tumor on CT-scans or MR imaging of their pituitary glands. In contrast to patients with ectopic ACTH production, plasma ACTH concentrations in patients with spontaneous disease are generally within the normal range. We describe here a patient with a pituitary macroadenoma that showed evidence of necrosis on MRI. The patient had an atypical clinical presentation with plasma ACTH levels considerably higher than that seen in patients with non-ectopic ACTH-secretory syndrome, markedly elevated urine free cortisol, lack of phenotypical signs of hypercortisolism such as wide purplish striae, and whose most prominent and distressing symptom was severe myopathy that resulted in the patient becoming bed-ridden. Psychosis was another striking feature in this patient who during his hospital course developed multiple opportunistic infections that contributed to his demise.

Complete remission of epileptic psychosis after temporal lobectomy: case report.

We report a case of a female patient with refractory complex partial seizures since 15 years of age, recurrent postictal psychotic episodes since 35 which evolved to a chronic refractory interictal psychosis and MRI with right mesial temporal sclerosis (MTS). After a comprehensive investigation (video-EEG intensive monitoring, interictal and ictal SPECT, and a neuropsychological evaluation including WADA test) she was submitted to a right temporal lobectomy. Since then, she has been seizure-free with remission of psychosis, although with some persistence of personality traits (hiperreligiosity, viscosity) which had been present before surgery. This case supports the idea that temporal lobectomy can be a safe and effective therapeutic measure for patients with MTS, refractory epilepsy and recurrent postictal epileptic psychosis or interictal epileptic psychosis with postictal exacerbation.

Improvement in severe self-mutilation following limbic leucotomy: a series of 5 consecutive cases.

BACKGROUND: The efficacy of neurosurgical intervention for self-mutilation behavior associated with severe, intractable psychiatric disorders remains undetermined. We report the effects of limbic leucotomy in 5 consecutive patients with severe self-mutilation behaviors. METHOD: After unsolicited referrals from their psychiatrists and careful consideration by the Massachusetts General Hospital Cingulotomy Assessment Committee (MGH-CAC), 5 patients were treated with limbic leucotomy. Their primary DSM-IV psychiatric diagnoses were either obsessive-compulsive disorder or schizoaffective disorder. Comorbid severe, treatment-refractory self-mutilation was an additional target symptom. Outcome was measured by an independent observer using the Clinical Global Improvement. Current Global Psychiatric-Social Status Rating, and DSM-IV Global Assessment of Functioning scales in addition to telephone interviews with patients, families, their psychiatrists, and treatment teams. The mean postoperative follow-up period was 31.5 months. RESULTS: All measures indicated sustained improvement in 4 of 5 patients. In particular, there was a substantial decrease in self-mutilation behaviors. Postoperative complications were transient in nature. and postoperative compared with preoperative neuropsychological assessments revealed no clinically significant deficits. CONCLUSION: In carefully selected patients as described in this report, limbic leucotomy may be an appropriate therapeutic consideration for self-mutilation associated with severe, intractable psychiatric disorders.

Egas Moniz and the origins of psychosurgery: a review commemorating the 50th anniversary of Moniz's Nobel Prize.

Modern psychosurgery began in 1936 with the work of the Portuguese neurologist, Egas Moniz, who attempted to treat the symptoms of mental illness by severing neural tracts in the frontal lobes. This procedure eventually became widespread and applied to thousands of institutionalized, psychotic patients in the United States and other countries. Despite serious side effects associated with psychosurgery, the apparent importance and validity of the treatment was recognized in 1949 when Moniz received the Nobel Prize for his innovation. Psychosurgery was largely replaced by anti-psychotic drugs in the mid-1950s, and the procedure and its practitioners rapidly fell into disrepute. This article reviews Moniz's career, the factors that led up to his first clinical trials of frontal lobe surgery, and the circumstances that allowed psychosurgery to flourish in the 1940s, eventually leading to Moniz's Nobel Prize.
