In support of the ICRF experiments planned on the Wendelstein 7-X (W7-X) stellarator, i.e. fast ion generation, wall conditioning, target plasma production and heating, a first experimental study on plasma production has been made in the Uragan-2M (U-2M) stellarator using W7-X-like two-strap antenna. In all the experiments, antenna monopole phasing was used. The W7-X-like antenna operation with launched radiofrequency power of ~100 kW have been performed in helium (p = (4–14) × 10−2 Pa) with the vacuum vessel walls pre-loaded with hydrogen. Production of plasma with a density higher than 1012 cm−3 was observed near the first harmonic of the hydrogen cyclotron frequency. Operation at first hydrogen harmonic is feasible in W7-X future ICRF experiments.
Neural Networks applied to Machine Translation need a finite vocabulary to express textual information as a sequence of discrete tokens. The currently dominant subword vocabularies exploit statistically-discovered common parts of words to achieve the flexibility of character-based vocabularies without delegating the whole learning of word formation to the neural network. However, they trade this for the inability to apply word-level token associations, which limits their use in semantically-rich areas and prevents some transfer learning approaches e.g. cross-lingual pretrained embeddings, and reduces their interpretability. In this work, we propose new hybrid linguistically-grounded vocabulary definition strategies that keep both the advantages of subword vocabularies and the word-level associations, enabling neural networks to profit from the derived benefits. We test the proposed approaches in both morphologically rich and poor languages, showing that, for the former, the quality in the translation of out-of-domain texts is improved with respect to a strong subword baseline.
There is a substantial proportion of patients who drop out of treatment before they receive minimally adequate care. They tend to have worse health outcomes than those who complete treatment. Our main goal is to describe the frequency and determinants of dropout from treatment for mental disorders in low-, middle-, and high-income countries.
Respondents from 13 low- or middle-income countries (N = 60 224) and 15 in high-income countries (N = 77 303) were screened for mental and substance use disorders. Cross-tabulations were used to examine the distribution of treatment and dropout rates for those who screened positive. The timing of dropout was examined using Kaplan–Meier curves. Predictors of dropout were examined with survival analysis using a logistic link function.
Dropout rates are high, both in high-income (30%) and low/middle-income (45%) countries. Dropout mostly occurs during the first two visits. It is higher in general medical rather than in specialist settings (nearly 60% v. 20% in lower income settings). It is also higher for mild and moderate than for severe presentations. The lack of financial protection for mental health services is associated with overall increased dropout from care.
Extending financial protection and coverage for mental disorders may reduce dropout. Efficiency can be improved by managing the milder clinical presentations at the entry point to the mental health system, providing adequate training, support and specialist supervision for non-specialists, and streamlining referral to psychiatrists for more severe cases.
Nowadays several authors defend the existence of an obsessive-compulsive (OC) spectrum in which eating disorders (ED), especially anorexia nervosa, would be include. We investigated the presence of OC symptoms in bulimic and anorexic patients and its relationships with personality traits.
The Maudsley Obsessive Compulsive Questionnaire (MOCQ) and the revised version of the Temperament and Character Inventory (TCI-R) were administered to patients and healthy controls.
Patients show higher scores than controls in the global punctuation of de MOCQ, and in the checking and doubt subscales. Cases also score higher in harm avoidance (dimension associated with personality disorders of cluster C) and in its subscale anticipatory worry. No differences were found between patients subgroups.
Restricting Anorexia Nervosa (RAN, n = 21)
Binging-Purging Anorexia Nervosa (BPAN, n = 29)
Bulimia Nervosa (BN, n = 34)
Control (C, n = 52)
RAN, BPAN, BN > C
Checking subscale (MOCQ)
BPAN, BN > C
RAN, BPAN, BN > C
Harm avoidance (TCI-R)
BPAN, BN > C
Anticipatory worry vs optimism (TCI-R)
RAN, BPAN, BN > C
Patients present more OC behaviours in comparison with healthy population but measures of obsessivity do not differ between the types of ED. Traits of personality characteristically associated to cluster C and to anxiety disorders seem to be also common features. These results do not support a separated classification of RAN into the OC spectrum.
Mixed Bipolar patients are those who have co-existing depressive symptoms during mania. These patients are supposed to have a worse evolution.
The objective of this study was to compare the long-term outcomes of patients who had at least one mixed episode with those who experienced only pure manic episodes.
169 outpatients diagnosed of Bipolar I disorder and treated at least during two years were included. 120 patients (71%) complited the follow-up over 10 years. Baseline demographic and clinical variables were included.
The patients with mixed episodes (37%) had a significantly younger mean age at onset comparing with those with manic episodes (25.3 years vs. 30.8 years; p=0.025) they also had more previous mood- incongruent psychotic symptoms χ2= 6.77, p=0.034), more number of hospitalizations (OR= 1.36, 95% CI = 1.14; -1.63; p< 0.001), and more number of episodes (OR= 1.21, 95% CI = 1.10-1.31; p< 0.001). There were no significant differences relating to depressive episodes, alcohol use, drug abuse, suicidal behaviour and suicide attempts.
Age at onset differed significantly between the mixed episode and pure mania groups, with mixed episode patients having a younger age of onset. This is interesting as one of the major results of the study we have found that age at onset mediates some of the factors classically related to outcome in mixed episodes like alcohol abuse and suicide attempts. However, independently of age at onset, these patients represent a especially severe type of bipolar disorder.
To determine the clinical profile of patients diagnosed of delusional disorder (DD) admitted to a psychiatric ward.
Retrospective chart review of inpatients with diagnoses of delusional disorder (DD) according ICD-10 criteria admitted to a psychiatric ward (Hospital de Conxo, Santiago de Compostela) between January 1998 and December 2008. Sociodemographic and clinical variables were collected, with special attention to comorbidity and presumed risk factors.
The sample consisted in 56 inpatients (30 women, mean age 54 ± 11). 64.3% were single including never married (33.9%), divorced, separated and widowed and 33.9% lived alone. The most frequent type of DD was persecutory (67%) followed by mixed type (16%). 16.1% presented hallucinations (most frequent auditory). In comparison with the other types, patients with persecutory delusions usually lived alone (p < 0.05). Most frequent comorbidities were substance abuse and affective disorders. Familiar background of psychoses was recorded in 21.4% and history of emigration in 12.5%. 5.4% suffered deafness. During the period studied 53.6% were admitted two or more times. After the most recent admission 32.1% were on depot antipsychotic.
In concordance with other previous reports, DD seemed to be more prevalent in women in middle or late adulthood and persecutory were the most frequent delusions. In our sample, most patients were not married and high prevalence of family antecedents of psychoses was found. It could be related with its hospital origin; then it could be hypothesized living alone and having familiar background of psychoses to be risk factors of hospitalization.
The aim of this study is to assess the personality traits in a sample of Spanish anorexic and bulimic outpatients.
The revised version of the Temperament and Character Inventory was administered to 76 women attended in an Eating Disorders Unit and to 46 healthy controls. Both groups were matched by gender, age and instruction.
Diagnoses in the sample were distributed as follows: bulimia nervosa (BN) 33, binging-purging type anorexia nervosa (BPAN) 23 and restricting anorexia nervosa (RAN) 18. RAN patients were significantly younger (21.6 vs. 26.3 p < 0.01). Differences in the harm avoidance, persistence and selfdirectedness subscales of the TCI were found (see table).
BPAN, BN > C
RAN > C
C > RAN, BPAN, BN
In concordance with previous reports, compared with healthy controls, patients show lower scores in self-directedness. Persistence seems to be associated with restricting behaviours, whereas harm avoidance with binging and purging. RAN trends to have low scores in novelty seeking items and BN shows lower reward dependence, but this differences are not statistically significant, perhaps because of sample size.
Describe Attention Deficit Hyperactive Disorder's (ADHD) prevalence in Bipolar Disorders (BD) and relatives.
78 admissions for Bipolar Disorder (DSM-IV) in Impatient Psychiatric Unit, in Hospital Clínico Universitario of Valladolid (Spain). Only 36/78 patients participate in study. Demographic, social and clinical information were registered. ADHD symptomatology was evaluated from patient and descendant (Conners short version).
ADHD symptomatology suggestive in childhood/adolescence were detected in 13,9% (5/36). Conners score were negative (below 15) in all case.
ADHD symptomatology suggestive in their children were detected in 6,25% (n=3). Conner score were positive in 2,1%. Family psychiatry history in 72,2% (n=26), affective disorder in 60,52% (n=23). No family history with ADHD diagnosis. Only one case (2,8%) with symptomatology suggestive of ADHD in relatives.
The ADHD prevalence in our sample of BD and relatives weren’t higher than general population.

Suicide is one of the most frequent causes of death. In 1993, Bleuler emphasized its importance in his “Suicidal behavior is the most serious symptom of schizophrenia”. Since then, various studies have confirmed importance of suicide in schizophrenia, and today it's clear that his research and knowledge is one of the great challenges of psychiatry.
- Establish clinical-socio-demographic profile and risk factors for psychotic people with autolytic behaviors.
- Determine frequency of suicides in psychotic disorders in our area of care.
Material and methods
Retrospective study(3 years evolution) that includes psychotic patients(diagnosed according DSM IV-TR) admitted to the HCU of Valladolid. With data provided by hospital medical records, analyzed socio-demographic variables and clinics. Study consists of two groups:group of cases(those patients who have suicidal behavior) and control group (those that haven't autolytic gesture during the study period). Statistical evaluation was performed with SPSS.
- The sample includes 191 patients:41(21%) have attempted suicide.
- Of them:73% are males;88% singles;51% have basic studies;61% we re unemployed;37% were 31-40 aged;54% started disease 21-30 aged and 63.5% are schizophrenic.
- Considering statistical study we find that suicidal patient profile is male(p = 0.039),diagnosed with schizophrenia(p = 0.033),with previous suicide attempts(p = 0.009)and lack of social support(p = 0.007).
- 21% of hospitalized psychotic patients have presented some autolytic attempt.
- Profile of suicidal psychotic patient is a male, single, 21-40 aged, primary education, unemployed, with a primary diagnosis of schizophrenia, particularly paranoid, with ten years evolution,without acceptable social support, number of revenues higher than non-suicidal psychotic and a personal history of previous autolytic attempts.
To compare the efficacy and safety of the intramuscular formulations of ziprasidone and haloperidol in treating agitation in schizophrenic patients attended in an emergency room.
Consecutive patients were alternatively assigned to receive 20 mg of IM ziprasidone or 10 mg of IM haloperidol. Efficacy measures were improvement in Behavioral Activity Rating Scale (BARS), in the sum of five items of the Positive and Negative Syndrome Scale that focused on agitation (PANSS-A) and scores on the Clinical Global Impression improvement scale (CGI-I), obtained 45 minutes and 2 hours after the IM medication. Tolerability assessments included changes in ECG, monitoring of vital signs and register of adverse events.
Finally 18 patients (13 men, mean age 40.8 ±10.2) were included in the analysis of data. At arrival in the emergency room, there were no differences between ziprasidone (Z) and haloperidol (H) groups in age, mean QTc length, mean BARS and mean PANSS-A scores. Analyzing the global sample there was an improvement in agitation scores. No significant differences were found between the groups in change of BARS and PANSS-A scores, in CGI-I scores or in the variation of the length of QTc interval at two hours. No serious adverse events were reported.
In spite of the small sample size, both treatments ziprasidone IM and haloperidol IM seems to be similarly effective for the management of psychotic agitation in the emergency room. Both were well tolerated. Lengthening of QTc interval due to ziprasidone IM had not been found in our sample.
UPD is a regional referral hospital psychiatric care unit, endowed with multidisciplinary equipment. It provides care to people with light/moderate/severe intellectual incapacity coexisting with mental disease and/or severe behavioral disorders. It offers attention to patients who need a protected therapeutical environment for correcting behavior disorders. It was opened in September 2008.
Description of:therapeutic goals, inclusion/exclusion criteria, admission protocol and psychotherapeutic/pharmacological interventions.
Analysis of inpatients's sociodemographic/clinical characteristics and preliminary assessment of therapy goals.
Retrospective study(13-month) of patients admitted to UPD of Leon Hospital from its inception to date. Data are collected from medical histories.
47 referrals have been received,5 of them have been rejected not to fulfill criteria. We’ve 16 patients on waiting list.32 incomes have been realized and 22 discharges have occurred.
19 of the incomes correspond to Mild,6 to Moderate,6 to Severe and 1 to Profound mental Retardation.
Regarding co-morbidity:22 patients presented serious behavioral disorder. From this group, 2 met criteria for autistic disorder, 5 had schizophrenia or unspecific psychotic disorders, 5 presented Personality Disorder and one ADHD.
10 patients did’nt present any important behavioral disturbance. From this group 2 were diagnosed with OCD,3 presented problems due to Alcohol and Substance-related Disorders,3 had Psychotic Disorders, one met criteria for Impulse Control Disorder and one presented Mood Disorder.
Before admission, 12 patients resided in specific handicappeds center, 5 intermittently at selected centers and in family, and 15 lived with family.
Psychotherapeutic intervention and treatment were useful in most cases. It was particularly helpful in treatment of behavioral disturbances. Now we must determine effectiveness in maintenance of improvement when they return to their community.
The complex interrelationship between personality disorders and bipolar disorders is still a controversial aspect with multiple diagnosis, therapeutic and ethiologic implications.
Comorbidity has been defined as the presence of more than one disorder in the same patient at the same time.
We made a literature review between 1995 and 2005 about comorbidity in bipolar and personality disorders.
There are different studies that agree the theory that personality disorders are previous forms of bipolar disorders.
Besides, it is important to consider the effect that bipolar disorders have over personality.
In the last years, different authors have suggested that co-morbid personality disorders predict a worse evolution in the course of the bipolar disorders, finding recurrent and resistant to treatment affective symptoms.
The co-occurrence studies of personality and affective disorders have ranged from 3 to 70%.
If we take the global n (428) of all the reviewed articles, we see that the percentage of comorbidity between personality disorders and bipolar disorders is almost the 48% of the studied patients. Looking at the most prevalent cluster, cluster A is the 13%, cluster B is near the 39% and cluster C the 35%.
Personality traits, dimensions and personality disorders seem to play an important role in the evolution of bipolar disorders.
The identification of these specific personality traits and the knowledge of the influence in the evolution of the illness are extremely important in the treatment and prevention of bipolar disorders.
Musical hallucinations are a rare phenomenon in clinical practice. The purpose of this study was to analyze the clinical spectrum of musical hallucinations.
We analysed demographic and clinical features of cases published in English, Italian, French or Spanish between 1991 and 2006 registered in MEDLINE, including three of our own cases. The cases were separated into four groups according to their main diagnoses (hearing impairment; psychiatric disorder; neurological disorder; toxic or metabolic disorder).
115 patients with musical hallucinations were included, of which 63.5% were female. The mean age was 57,25 years. Main diagnoses were: psychiatric disorder (46.1%; schizophrenia 30.4%), neurological disorder (21,7%), hearing impairment (17,4%), toxic or metabolic disorder (12.2%) and 2.6% other diagnoses.
61.7% patients presented simple diagnoses while 36.5% presented two or more diagnoses. 2.1% of patients didn't receive any diagnoses. 35.7% of patients and 60.9% of non psychiatric patients presented hearing impairment.
Both instrumental and vocal were the more frequent musical hallucinations and most of the patients had insight about the abnormality of their perceptions. Another kind of hallucinations was present in 40.9% of patients, auditory hallucinations being the most common. Also, 38,3% of the global sample had abnormalities in brain structural image (MRI, CT).
Musical hallucinations are a heterogeneous phenomenon in clinical practice. published cases describe them as more common in women and in psychiatric and neurological patients. Hearing impairment seem to be an important risk factor in the development of musical hallucinations.
To complete missing information on the influence of spiritual and religious advisors as informal providers for mental health problems in Europe.
Recourse to religious practice or belief when coping with mental health problems was evaluated using data from the ESEMED survey. This was a stratified, multistage, clustered-area probability sample survey of mental health carried out in six European countries which included 8796 subjects. Between countries differences in sociodemographic characteristics, religious affiliation, and prevalence of mental disorders and management of mental disorders were evaluated.
Religion appears to play a limited role in coping with mental health problems in Europe. Only 7.9% of individuals seeking help for such problems turned to a religious advisor. This proportion differed between countries from 13% in Italy, 12.5% in Germany, 10.5% in the Netherlands, 5.8% in France, 4.7% in Belgium to 4% in Spain. In addition, seeking help exclusively from religion was reported by only 1.3% of subjects. Practicing religion at least once a week and considering religion as important in daily life were predictors of using religion versus conventional health care only. Use of religion was not influenced by gender and age. Non-Christian respondents and individuals with alcohol disorders were more likely to use religion. In Spain, the use of religion is much lower than average.
Unlike the situation in the United States, organised religion does not provide alternative informal mental health care in Europe. At best, it could be considered as an adjunct to conventional care.
Auditory and musical hallucinations have been reported in patients as an adverse effect of the use of opioids. Hearing loss, old age, and female gender are considered risk factors in the development of musical hallucinations. The aim of this report is to describe a case of a patient with auditory and musical hallucinations and to discuss the role of an opioid –tramadol- in the origin of those.
An 80 years old woman experiencing auditory hallucinations was referred to our hospital from an emergency room. The patient had bilateral mild hearing loss and was receiving tramadol 112.5 mg/daily during the last year for cervical pain. In the last ten months, she had been gradually noticing the voice of her dead husband coming from under her pillow, as well as intermittently hearing popular songs being played inside her head. The patient had good insight on both types of abnormal perceptions, which were reported as increasingly unpleasant through time.
Tramadol was discontinued and pimocide (range 1-4 mg/day) and loracepam (2.5 mg/day) were introduced, achieving the improvement of the hallucinations and the anxiety associated with them.
The outcome of this case supports the hypotheses that Opioids could induce musical hallucinations. Hearing impairment, old age, and gender could be underlying risk factors on the development of musical hallucinations.
In 1916 Wimmer described psychogenic psychosis as a psychosis secondary to mental trauma.
Currently, psychogenic psychosis is included among acute and transient psychotic disorders (F23) in the ICD-10 and among the brief psychotic disorders (298.8) in the DSM IV-TR.
We review the case histories of patients diagnosed with psychogenic psychosis for the purpose of analysing the stability of the diagnosis and its current validity.
Material and methods:
The sample consisted of 15 patients admitted to the Psychiatric Department of the Conxo Hospital in Santiago de Compostela (Spain) with a diagnosis of psychogenic psychosis between 1998 and 2006. A descriptive analysis was made based on a series of socio-demographic and clinical variables. Afterward, in October 2006, patients were followed up in their respective mental health units to verify their current diagnosis and clinical status.
The sample included 14 women and 1 man with mean age of 33,7 years. The most frequent prior personality trait was histrionic (42%). Persecutory delusions (58%) and auditory hallucinations (46%) were the predominant psychotic symptoms. In the months after follow-up, the majority of patients maintained the diagnosis of psychogenic psychosis (73%), while 9% of patients were diagnosed with dysthymia, and 2 patients developed schizophrenia with deterioration.
The majority of patients in our sample diagnosed with psychogenic psychosis maintain a stable diagnosis over time and do not present deterioration.
Despite the high prevalence of obsessive-compulsive symptoms located around 2-3% of the population, there continue to be cases where the characteristics of the patient or the circumstances of their environment, they fall short queries mental health or when they do not for the disorder itself, but for another reason obsessional symptoms worsen.
Expose using clinical case, the existence of patients with obsessive pathology whose characteristics do not seek mental health consultation, until this is associated with a new disease that interferes significantly in vital organization.
We report the case of a man of 88 years old, married at 60, was admitted to the psychiatric consultation at the request of his wife 29 years his junior, for behavioral disorders several years of evolution and history of obsessive symptoms compulsive, which did not interfere with their daily lives by the lack of insight and poor social environment
OCD is included in anxiety disorders.
It is characterized by the presence of obsessions and compulsions that interfere with personal, work and / or patient's social.
There are cases that own personality traits of the patient, this disorder is not diagnosed early and choose to go only when associated with worsening cognitive impairment rituals and interfere with family life.
Ekbom's syndrome or delusional parasitosis (DP), is an “uncommon psychiatric syndrome” characterized by the presence of delusion of infestation.
The syndrome may be seen in association wiht a number of neuropsychiatric conditions, including bipolar disorder, paranoia,schizophrenia, dementia, depression as well as abuse of drugs, such as cocaine or amphetamines. Previously, DP was often considered to be a monosymptomatic hypochondraical psychosis. Delusions of parasitosis has also been reported in association with a number of medical conditions that are characterized by itching.
To review the literature through a case report.
A 52 year-old female, unmarried who lives alone, was admitted for parasitosis delusions that had started in the last two months. She complained of vermins crawling through her skin, mainly on her face and scalp. The illness began with pricking and itching sensations on her head. She used to put the “little animals” in a piece of paper to prove their existence. Risperodone was started up to 3 mg per day. She had a progressive clinical improvement and in one week was discharged.
In conclusion, rather than a unique illness, DP is a neuropsychiatric syndrome that can follow primary psychotic and depressive disorders, dementia or other organic diseases. The typical patient is an elderly woman who is unmarried or living along.
There have been no double-blind studies confirming that atypical antipsychotics are more effective than pimozide in the treatment of DP. Further trials are warranted to study the true efficacy of atypical antipsychotics in the treatment of DP.
In this exhibition we aim to describe a clinical case and the different consequences that may present additional problems with eating disorders, focusing with emphasis on development and clinical picture. This disorder usually occurs in non-obese adolescents accused, showing symptoms significantly related to interpersonal functioning of these adolescents, who tend to be isolated or seek company of younger guys. They are characteristic of obsessive-compulsive disorders related or unrelated to the food. Dietary restriction involves biological and physical changes, highlighting the alteration of hypothalamic and endocrine system, leading to signs and symptoms such as amenorrhea, cold intolerance, hypotension … Neurochemical changes have also been attributed to malnutrition.
The present case is a 31 year old woman. Initiates contact with Mental Health at age 15 by anorexia nervosa. Patient requests for worsening nutritional status, family relationships, and alcohol consumption, being the turning point and main motivation, the birth of his daughter. 8 months ago gave birth, being an unexpected delivery at home. Unaware that pregnancy, justifying as secondary amenorrhea eating disorder and abdominal inflammation malnutrition. Daughter born seven months income requires low weight and withdrawal symptoms during pregnancy as continuous with anxiolytic and antidepressant treatment.
It has a favorable, always maintaining therapeutic commitment announced at the beginning of tratamiento. Currently still in out patient reviews with Psychiatry, Clinical Psychology, Nursing and Nutrition.
