Objective:
Verbal fluency tasks evaluate executive functioning by requiring a person to provide words within a certain time period that start with a certain letter (phonemic fluency) or category (semantic fluency). Research shows that age impacts test takers’ phonemic and semantic verbal fluency performance. In fact, it has been suggested that phonemic verbal fluency peaks around age 30 to 39 and begins to decline at older ages. In contrast to phonemic fluency, research suggests that semantic fluency increases steadily between test takers until age 12 and begins declining around age 20. A generation is a cohort of people born within a certain period who share age and experiences. Studies show that Generation X individuals (persons born between 1965-1980) outperform Generation Y (persons born between 19811995) and Generation Z individuals (persons born between 1965-1980) on the Cordoba Naming Test. To our knowledge, no study has investigated verbal fluency performance across generational groups. We predicted that Generation X individuals would outperform individuals from Generation Y and Z on both verbal fluency measures.
Participants and Methods:The sample of the present study consisted of 107 participants with a mean age of 27.39 (SD = 9.16). Participants were divided into three groups: Generation X (n = 19), Generation Y (n = 52), and Generation Z (n = 36). The phonemic verbal fluency task consisted of three trials and the semantic verbal fluency task consisted of one trial, one minute each. A series of ANCOVAs with Bonferroni post-hoc tests were used to evaluate verbal fluency performance between generational groups. All participants passed performance validity testing.
Results:We found significant differences between our generational groups on both verbal fluency tasks. Post-hoc tests revealed that the Generation Y group outperformed both Generation X and Z groups on both verbal fluency tasks, p’s <.05, np2 =.11 -.16. No significant differences were found on either verbal fluency task between the Generation X and Z groups.
Conclusions:Contrary to our hypothesis, Generation Y individuals possessed better phonemic and semantic fluency than both Generation X and Z individuals. Meanwhile, Generation X individuals did not significantly differ on any of the verbal fluency tasks compared to Generation Z individuals. Speaking multiple languages has been shown to impact verbal fluency performance. In our sample, the Generation X and Z groups consisted primarily of bilingual speakers compared to the Generation Y group. Examining generational differences is essential to understand the unique characteristics and impact of the times in which various individuals have grown up. Future research, for instance, should evaluate the influence of bilingualism across generational groups on verbal fluency performance.

Objective:
A 30-item confrontation naming test was developed in Argentina for Spanish speakers, The Cordoba Naming Test (CNT). The Boston Naming Test is an established confrontation naming task in the United States. Researchers have used the Boston Naming Test to identify individuals with different clinical pathologies (e.g., Alzheimer’s disease). The current literature on how Spanish speakers across various countries perform on confrontational naming tasks is limited. To our knowledge, one study investigated CNT performance across three Spanish-speaking countries (i.e., Argentina, Mexico, and Guatemala). Investigators found that the Guatemalan group underperformed on the CNT compared to the Argentine and Mexican groups. The purpose of this study was to extend the current literature and investigate CNT performance across five Spanish-speaking countries (i.e., Argentina, Mexico, Guatemala, Colombia, United States). We predicted that the Argentine group would outperform the other Spanish-speaking countries.
Participants and Methods:The present study sample consisted of 502 neurologically and psychologically healthy participants with a mean age of 29.06 (SD = 13.41) with 14.75 years of education completed (SD = 3.01). Participants were divided into five different groups based on their country of birth and current country residency (i.e., United States, Mexico, Guatemala, Argentina, & Colombia). All participants consented to voluntary participation and completed the CNT and a comprehensive background questionnaire in Spanish. The CNT consisted of 30 black and white line drawings, ranging from easy to hard in difficulty. An ANCOVA, controlling for gender, education, and age, was used to evaluate CNT performance between the five Spanish-speaking country groups. Meanwhile, a Bonferroni post-hoc test was utilized to evaluate the significant differences between Spanish-speaking groups. We used a threshold of p < .05 for statistical significance.
Results:Results revealed significant group differences between the five Spanish speaking groups on the CNT, p = .000, np2 = .48. Bonferroni post-hoc test revealed that the United States group significantly underperformed on the CNT compared to all the Spanish-speaking groups. Next, we found the Guatemalan group underperformed on the CNT compared to the Argentinian, Mexican, and Colombian groups. Additionally, we found the Argentinian group outperformed the Mexican, Guatemalan, and United States groups on the CNT. No significant differences were found between the Argentinian group and Colombian group or the Mexican group and Colombian group on the CNT.
Conclusions:As predicted, the Argentinian group outperformed all the Spanish-speaking groups on the CNT except the Colombian group. Additionally, we found that the United States group underperformed on the CNT compared to all the Spanish-speaking groups. A possible explanation is that Spanish is not the official language in the United States compared to the rest of the Spanish-speaking groups. Meanwhile, a possible reason why the Argentinian and Colombian groups demonstrated better CNT performances might have been that it was less culturally sensitive than the United States, Mexican, and Guatemalan groups. Further analysis is needed with bigger sample sizes across other Spanish-speaking countries (e.g., Costa Rica, Chile) to evaluate what variables, if any, are influencing CNT performance.

Objective:
The Boston Naming Test (BNT) is a 60-item confrontation naming task requiring participants to name a series of pictures. Prior research has shown that bilingual children have smaller vocabularies than monolinguals and that this effect continues into adulthood. Numerous studies have confirmed that bilingual adults name fewer pictures correctly than monolinguals on the BNT. Research also shows that self-reported workload correlates with neuropsychological test performance and that estimates of workload provide additional information regarding cognitive outcomes. Hardy and Wright (2018) conditionally validated a measure of perceived mental workload called the NASA Task Load Index (NASA-TLX; Hart & Staveland 1988) with healthy adults on a neuropsychological test (i.e., the Tower of Hanoi). Research also shows that bilinguals report higher perceived workloads on cognitive tasks compared to monolinguals. Although this work has recently extended to other tests, to our knowledge, the workload profile of the BNT remains relatively unexplored. We evaluated BNT performance and perceived workload via the NASA-TLX in monolinguals and bilinguals. We predicted that monolinguals would outperform bilinguals on the BNT, but that bilinguals would report higher workloads.
Participants and Methods:The study sample consisted of 84 healthy participants (36 monolinguals, 48 bilinguals) with a mean age of 28.94 (SD = 10.76). Participants completed the standard 60-item BNT in English. The NASA-TLX scale was utilized to evaluate perceived workload across six subscales. The NASA-TLX was also completed in English after the completion of the BNT. ANOVAs were used to test BNT performance and perceived workload ratings between our language groups.
Results:We found that monolinguals performed better on the BNT compared to bilinguals, p =.001, np2 = 24. However, bilinguals reported exerting more effort when completing the BNT compared to monolinguals, p =.002, np2 = .11. Additionally. bilinguals also experienced more frustration when completing the BNT compared to monolinguals, p =.034, np2 = .05.
Conclusions:As expected, results revealed that monolinguals outperformed bilingual participants on the BNT. However, bilinguals exerted more effort on the BNT and reported the BNT to be more frustrating. A possible reason for bilinguals underperforming and reporting higher perceived workloads on the BNT may be because correct responses were only accepted in English. This may have caused bilingual speakers to exert increased effort to complete the task in a non-native language. In turn, this increased effort likely increased cognitive load and led to higher frustration levels. Further research is needed to confirm our findings and support the idea that bilingualism leads to perceiving greater effort and frustration, and to determine whether there are subgroup differences in BNT performances among bilingual individuals (e.g., English learned as a first language compared to English learned as a second language).

Introduction
Obsessive-compulsive disorder (OCD) is a mental disorder in which patients who suffer from it have repetitive and undesirable thoughts, feelings, ideas, sensations (obsessions) and behaviors that drive them to do something over and over again (compulsions).
Often the person tries to get rid of the obsessive thoughts through compulsions, but this only provides short-term relief. Not carrying out the obsessive rituals can cause enormous anxiety and suffering.
ObjectivesTo describe a 23-year-old male patient, who suffers from anxiety and mood symptoms, reacts to ego-dystonic obsessive ideas and sexual content, of months of evolution, and who manages to calm down through compulsive masturbation or watching sexual videos on the internet. All this clinic negatively interferes with their quality of life, asking the patient for medical help to calm these ideas.
MethodsWe carried out a review in Pubmed with the terms Antiandrogens and TOC, in order to make a better description of the clinical case.
ResultsAfter several treatment attempts (Sertraline, Paroxetine, Clomipramine, Clomipramine + SSRI), reaching maximum doses according to clinical guidelines, and with poor therapeutic response, it was decided to discuss the case with the endocrinology department of our hospital, deciding to start treatment with antiandrogens, in order to alleviate the persistent intrusive ideas of a sexual nature. The administration of antiandrogens in men can cause a decrease or increase in the development or involution of secondary sexual characteristics in men, reducing the activity or function of accessory sexual organs, and hyposexuality, with decreased sexual desire or libido.
After several weeks, there was improvement in the obsessive symptoms with a decrease in compulsive rituals. However, after the 3rd mo, some symptoms reappeared, but not with the same severity and intensity as before treatment. In addition, we cannot ignore the adverse effects that have occurred, such as involution of secondary sexual characteristics. However, and taking into account the negative repercussion that this clinic had on the patient’s quality of life, the benefit obtained exceeded the risk, having noted clear improvement with this therapy, and maintaining evolutionary controls by both psychiatry and endocrinology.
ConclusionsPatients suffering from obsessive-compulsive disorder can be effectively treated with anti-androgenic pharmacological agents with various modes of action. The most effective group of such agents is the long-acting analogues of the gonadotropin-releasing hormone. The objective of this review is to elucidate the possibility of using such powerful anti-androgenic agents in the treatment of obsessive-compulsive disorder.

Introduction
Catatonia is a complex psychomotor syndrome that often goes unrecognized and, consequently, untreated. Prompt and correct identification of catatonia allows for highly effective treatment and prevention of possible complications. Benzodiazepines and electroconvulsive therapy (ECT) are the most widely studied treatment methods. However, no uniform treatment method has yet been brought forward and no previous attempts to treat catatonia on a patient suffering concomitant major depressive disorder (MDD) with NMDA receptor antagonists have been documented so far.
ObjectivesTo describe the unknown and novel management of catatonia and MDD with intranasal esketamine, a NMDA receptor antagonist.
MethodsA 55-year-old woman with a diagnosis of long-standing recurrent major depressive disorder who was admitted to the psychiatric inpatient unit of UniversityHospital Marqués de Valdecilla (Santander, Spain) suffering a complex catatonic, mutative state framed on a severe MDD. Different ineffective therapeutic interventions were deployed during the course of her illness. After failing to improve under conventional pharmacological treatment and ECT, and given the complexity of peripheral venous access on this patient (which disabled the option for iv ketamine use), we decided to initiate compassionate treatment with intranasal esketamine.
ResultsIntranasal esketamine was effective in the resolution of patient’s complex catatonic state. Clinical response from catatonia was observed after 6 intranasal esketamine administrations (2-week follow-up), reaching full catatonia and MDD remission after 12 sessions in absence of significant adverse events
ConclusionsEsketamine showed promising effectiveness for the treatment of catatonia in the context of MDD, although further research on this topic is needed.

Introduction
A review of the literature shows how female sex is a crucial factor in the development of ED, being the proportion of women and men 10 to 1 regardless of the location of the sample (Duncan, Ziobrowski & Nicol, 2017) and different clinical subtypes (AN, BN) (Swanson et al., 2011). However, male population has always been less studied, some works find that only 1% of the articles published in AN is aimed at the study of males (Galusca, 2012).
Nowadays it is accepted that the etiopathogenesis of these disorders is multifactorial and in addition to female gender other risk factors have been identified, such as neurobiological alterations, psychological predictors, personality traits, low self-esteem, extreme perfectionism or thinness values focused on body and figure. On the other hand, certain impulsive behaviours such as self-harm, substance use, physical activity or diets are factors that may be confused as predisposing or as symptoms of the pathology itself (Connan et al., 2003, Treasure, Stein and Maguire, 2015).
Recently, Kinasz, Accurso, Kass and Le Grange (2016) have compared the clinical characteristics that differentiate men (59) from women (560) in a sample of children and adolescents between 6 and 18 years-old, finding that males presented an earlier start of the ED and not appreciating differences in the duration of the disease, income, episodes of purgue and psychiatric comorbidity of anxiety, behaviour disorders or impulsivity.
ObjectivesThe aim of this study was to evaluate gender differences in clinical characteristics, levels of depression, previous obsessiveness and personality dimensions in eating disorders (ED) compared with controls.
MethodsA total of 80 participants was divided into 4 groups, 20 men and 20 women with ED and 20 men and 20 women without ED (healthy control), matched by age and socioeconomic status. The design of the study was case-control, and data was collected through clinical interview and a battery of cuestionaires.
ResultsMen with ED only differ in vigorous physical activity (measured by IPAQ) from controls and women with pathology. Regarding personality traits, men and women with ED do not differ among them, although they do differ in novelty search and harm avoidance respect to their controls.
ConclusionsBehaviors such as physical activity in males frame a slightly different way of reducing their discomfort, however, clinical implication indicates that the treatment may be similar according to gender.

In this paper we re-describe Trichuris muris based on morphological data following isolation from two commensal rodent species, Mus musculus from Mexico and Rattus rattus from Argentina. Furthermore, we provide a molecular characterization based on mitochondrial (cytochrome c oxidase subunit 1 mitochondrial gene) and nuclear (internal transcribed spacer 2 region) markers in order to support the taxonomic identification of the studied specimens of T. muris from M. musculus. We distinguished T. muris from 29 species of Trichuris found in American rodents based on morphological and biometrical features, such as the presence of a spicular tube, length of spicule, size of proximal and distal cloacal tube and non-protrusive vulva. We suggest that spicular tube patterns can be used to classify Trichuris species in three groups. Considering that the diagnosis among the species of this genus is mainly based on morphometry, this proposal represents a relevant contribution. We provide molecular studies on two markers, making this the first contribution for T. muris in the Americas. This study makes an important contribution to the integrative taxonomy of cosmopolitan nematode species, and its correct determination from the parasitological study of commensal rodents.

The annual migration of birds involves a very large number of inter-continental and intra-continental movements in which thousands of bird species participate. These migrations have been associated with the spread of pathogens worldwide, including bacteria, viruses and parasites. This study describes the case of a black stork (Ciconia nigra) that was ringed at the nest in Latvia and died five months later in the south-east of the Iberian Peninsula. Post-mortem examination revealed that the cause of death was electrocution. In addition, a massive infection by the trematode Chaunocephalus ferox (Digenea: Echinostomatidae) causing severe granulomatous lesions throughout the small intestine was detected. This is the first report of C. ferox infection in a black stork in the Iberian Peninsula, a trematode that, due to the severe lesions it causes, can affect the health of C. ferox-infected wild birds, particularly in severely infected long-distance migrants. The dispersal of platyhelminths associated with migratory birds is discussed. After the ringing at the nest, the black stork was sighted in Central Europe one month before its capture, and the trematodes found by necropsy were mostly mature adults. Consequently, we estimate that this juvenile animal acquired the infection during its migration in a European area other than the Iberian Peninsula, evidencing a long-distance parasite spread through its migratory host. Our study highlights that bird ringing can be used to understand the epidemiological implications that bird migratory behaviour may have on the dispersal of parasites.

Introduction
The compassionate use of intranasal esketamine is approved in Spain for treatment-resistant depression (TRD).
ObjectivesThe objective of the study is to assess the clinical stability in the medium-term follow-up of patients with TRD after esketamine use.
MethodsDescriptive, retrospective and multicenter study carried out in Spain. Patients with TRD who had received esketamine treatment, and for whom there were clinical data of subsequent evolution, were included. The scores on the MADRS and Hamilton scales were changed into scores on the CGI scale according to the studies by Leucht et al. The Student’s t test was performed to assess differences in the CGI.
ResultsEleven patients were included: 72.7% were women and the mean age was 56 (SD: 12.9). The maximum dose of esketamine used was 84mg in 63.7%. The onset of antidepressant action was observed from the 1st dose in 72.6% of the patients. The mean time in treatment was 6.6 months (SD: 2.3) and 90.9% reached remission criteria. After 7.4 months (SD: 3.0) from the end of the treatment, 90.9% remained in remission and without visits to the emergency room or hospitalization for psychiatric reasons. The mean baseline score on the CGI-SI was 5.7 points, at the end of the treatment was 1.2 points and after longitudinal follow-up it was 1. Statistically significant differences were observed (p<0.001) both at the end of the treatment and in the post-esketamine follow-up compared with baseline score.
ConclusionsIn our sample, the use of esketamine in TRD shows clinical stability in the medium-term follow-up.

Introduction
A 21-year-old woman diagnosed with bipolar disorder was hospitalized in the Mental Health Day Hospital of Salamanca during the Covid pandemic. The patient engaged with 4 different jobs and a master’s degree, beginning with verbose speech, dysphoria, global insomnia, grandiose delusions, extremely high energy and thinking she has the vaccine. She works the following objectives:illness insight, risk factors, psychopathological stabilization, social skills, slowing down of activities and taking responsibilities.
ObjectivesThe objective is do a follow-up of the patient during her hospitalization in the Mental Health Day Hospital and to carry out a structured search in PubMed and Up-to-Date about psychotherapy and bipolar disorder.
Methods3-month follow-up of a 21-year-old woman diagnosed with bipolar disorder during her hospitalization in the Mental Health Day Hospital in Salamanca and a structured search in PubMed and Up-to-Date in April 2021 in English, French and Spanish, including the last 10 years with the keywords “psychotherapy”, “psychotherapies” and “bipolar disorder “.77 studies were analyzed: 12 included, 65 excluded.
ResultsSeveral randomized trials highlight the efficacy of group psychoeducation and cognitive-behavioural therapy in relapse prevention, improving illness insight, medical adherence and less hospitalizations. Therapeutic alliance plays a significant role in the process. Our patient improved her knowledge of her illness and treatment, her social skills and reconnected with her relatives and slowed down her activity. She then was referred to her community mental heath center psychiatrist.
ConclusionsThe insight in bipolar disorder plays an important role in medical adherence and prevention of relapses. Therapeutic alliance improves their insight, their functionality in their daily life and enables close monitoring. Medical treatment should be accompanied by psychotherapy for a complete approach of the treatment.

Introduction
Chronic pain has an impact that goes beyond the physical plane and, over the years, it ends up deteriorating the emotional, working and social life of people who suffer it.
ObjectivesSince we are working with patients who suffer a chronic pathology that cannot be cured, the objective of the group is to create a safe space in which these patients can feel understood, facilitating emotional expression and promoting an active attitude. Accepting pain and its limitations allows the person to regain their ordinary life.
MethodsA multicomponent group therapy with a cognitive-behavioural orientation was carried out. The group was formed by 12 patients, all of them women with chronic pain. Eleven sessions were established on a weekly basis of one and a half hours of duration.
ResultsIn each session a specific aspect was worked on, favouring the learning of techniques, tools and strategies of coping. A global approach was made, including behavioural, cognitive and emotional elements. At the end of the process, the patients reported benefits in their ability to manage anxiety and depression symptomatology, and they reflected a lower impact of pain in their daily life.
ConclusionsGiven the complexity of the symptomatology in chronic pain, it is important to approach the treatment from a multidimensional perspective that envisages every component of pain in order to being able to give a response to the physical and psychosocial impact that it implies, favouring a better confrontation and adaptation.

Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of state. Neutron star mergers are expected to often produce rapidly rotating remnant neutron stars that emit gravitational waves. These will provide clues to the extremely hot post-merger environment. This signature of nuclear matter in gravitational waves contains most information in the 2–4 kHz frequency band, which is outside of the most sensitive band of current detectors. We present the design concept and science case for a Neutron Star Extreme Matter Observatory (NEMO): a gravitational-wave interferometer optimised to study nuclear physics with merging neutron stars. The concept uses high-circulating laser power, quantum squeezing, and a detector topology specifically designed to achieve the high-frequency sensitivity necessary to probe nuclear matter using gravitational waves. Above 1 kHz, the proposed strain sensitivity is comparable to full third-generation detectors at a fraction of the cost. Such sensitivity changes expected event rates for detection of post-merger remnants from approximately one per few decades with two A+ detectors to a few per year and potentially allow for the first gravitational-wave observations of supernovae, isolated neutron stars, and other exotica.

Background
Natural polyamines (putrescine, spermidine and spermine) are low molecular weight highly protonated aliphatic molecules that physiologically modulate NMDA, AMPA/kainate glutamatergic receptors and limbic dopaminergic neurotransmission. Previous studies had demonstrated that polyamine metabolism might be disrupted in schizophrenia, what could potentially be linked to glutamatergic dysfunction. In particular, polyamine levels in blood and fibroblast cultures from patients with schizophrenia had previously been found to be higher than in healthy controls. Indeed, a significant positive correlation between blood polyamine levels and severity of illness may exist.
MethodsIn order to test potential differences in blood polyamine levels between drug-free schizophrenia in-patients (n = 12), and healthy controls (n = 26, blood donors), spermidine (spd), spermine (spm), and spermidine/spermine index (spd/spm) were determined using HPLC after dansylation.
ResultsNo significant differences were found between groups (t = 0,974; df = 36; P = 0,337 for spd, t = l0, 52; df = 36; P = 0,959 for Spm, and, t = 0, 662; df = 36; P = 0,512 for spd/spm).
ConclusionsThough we couldn’t replicate previous findings suggesting disturbances in blood polyamine levels in schizophrenia, this issue may be a promising target. Future research should take into account possible factors such as sex, nutritional state, and stress.

Introduction
Psychotic spectrum diseases are one of the most expensive illnesses in our society. Being able to recover as much social and laboral activity as possible has to be the goal. Trying to achieve this objective, we face different problems, as for example therapeutic adherence.
ObjectivesShow the importance of an adequate treatment and adherence in order to keep the patient as much integrated in the society as possible, and in order to reduce the economic and social cost of the psychotic spectrum diseases.
MethodsCase report and bibliography review.
ResultsThe patient of this case is a 34 year old woman with a schizophrenia diagnosis given after 4 hospitalizations in psychiatry units. She had 4 years of stabilization taking an injectable antipsychotic, in which she was able to study and keep adequate familiar and sentimental relationships. After being badly recommended to retire her medication for some who identified himself as member of the “new psychiatry”, she began with new delusions and hallucinations which had to be treated at the Hospital Psychiatry Unit. She was close to get a statal job related to her architecture studies, but she was not able to go to the exam due to the exacerbation of her illness. In the review we see that the average economic cost per schizophrenic patient in developed European countries such as Germany is, at least, 14000€ per patient.
ConclusionsAdequate treatment adherence is highly important to keep an adequate control of the illness in order to sustain the better social live and job function.

Introduction
Directed by Edward Zwick “Pawn Sacrifice” is a biographical film released on September 2015. The film stars Tobey Maguire as Bobby Fischer, the American World Chess Champion, considered one of greatest player of all time. His career's peak was in 1972 when he captured the World Chess Championship from Boris Spassky of the USSR.
AimsWe tried to dig a little in the biography of Bobby Fischer who many described as mentally ill. We tried to figure out what is reality and what is just legend about Fischer. Our goal is promote chess, and also honour the great Fischer. Moreover, we wanted to explore the scientific literature published about the benefits of playing chess, especially in childhood.
MethodsWe made an exhaustive review of the author's life, and also testimonies of people who knew him. Moreover, we found some articles that review the relationship between chess and IQ trying to confirm or debunk some myths about this legendary game.
ResultsIt was incomprehensible to everyone that the top of the career of Bobby Fischer at the same time meant an abrupt and complete fall. One possible explanation for this attitude would be a mentally unbalance not specified disorder throughout his lifespan.
ConclusionsNot all geniuses are crazy, neither all crazy are geniuses. A genius is a person with extraordinary capabilities, that focused on a topic, has the ability to enlight new ways to explain this complex world, whether it is to create a symphony, paint masterpiece or the next move on the chessboard.

Introduction
Alcoholic hallucinosis is a rare complication of chronic alcohol abuse, characterized by acoustic verbal hallucinations and delusions, mainly of a menacing content, arising in clear consciousness, that appear during or shortly after a period of heavy alcohol consumption.
Objectives and aimsTo outline the key clinical features of alcoholic hallucinosis in order to improve differential diagnosis with other entities.
MethodsWe studied the evolution of an outpatient followed in a Mental Health Centre of Valladolid and compared it with present data about the condition, found in a bibliographic search of articles no older than 10 years about the topic.
ResultsPartial insight about the experience, along with clear consciousness, was key to discard other psychiatric diagnosis that also present acoustic hallucinations. Neuroimagining and functional tests in our patient showed moderate cognitive impairment and cortical atrophy, which contradicts other studies which claim that an acceptable level of cognition must be present in order to gain the necessary insight to meet the diagnostic criteria.
ConclusionsAlcoholic hallucinosis is a rare form of subacute encephalopathy, secondary to an abrupt stop in a previously chronic and heavy alcohol consumption. Its diagnosis is mainly clinical, and neuroleptics are the most used drug, being abstinence essential for an adequate evolution. The course is usually benign, although the acoustic phenomena may not disappear completely.

Introduction
Bupropion is a dual antidepressant, a norepinephrine and dopamine reuptake inhibitor. Its main use is in affective disorders as major depression. Antidepressants have been commonly associated with sexual side effects in the libido, sexual arousal, orgasm and erectile function. Bupropion has negative influence in sexual function, even it could increase the libido. Due to this, it could be a good option in patients with active sexual life and affective disorder.
Clinical reportA 58-year-old female with a long history of depression disorder for 5 years. History of lots of side effects with different treatments, sexual dysfunction with serotonin-antidepressants. Treated with bupropion SR 150 mg/day and alprazolam, she suffered a relapse. The bupropion was increased to 300 mg/day. Three days later she appeared in the consultation room, presented a sense of pre-orgasmic of 72 hours of evolution, high increased libido, tiredness, muscle tension and insomnia. This sense did not improve after the sexual act. It had never happened previously. The side effect improved when the bupropion was reduced to 150 mg/day and disappeared with its withdrawal.
ConclusionsThe case made a relationship between the increased of bupropion's dose and the appearance of unusual sexual side effects (increased of libido and pre-orgasmic sense). Not only bupropion is one of the antidepressants that do not cause sexual dysfunction, if not it was reported in some trials that could be a treatment against this dysfunction due to its prosexual effects. The mechanism is unknown but could be related with norepinephrine or dopamine transmission.

Introduction
Traumatic event related disorders (ASD, PTSD and dissociative disorders) could share a common dissociative psychobiological origin. Patients diagnosed with dissociative identity disorder present a high sexual abuse rate (85–90%), way above the rest of the traumatic spectrum disorders.
ObjectivesThe goal of this study is to analyse the existing relation between different types of trauma, especially sexual abuse, and the onset and continuity of dissociative disorders.
Materials and methodsWe report the case of a 37 years old woman with a long sexual abuse history. The symptoms appear by age 30, in the form of flashbacks, ushering a persistent identity fragmentation in individual differentiated opposed components, shaping a dissociative personality disorder, which was present for years taking a fluctuating and invalidating nature.
DiscussionWhen a traumatic event occurs, acute dissociative reactions frequently appear, usually briefly, disappearing spontaneously afterwards. In this case, we can discern the persistence of the dissociative symptoms and the repercussion they had in the patient's functionality.
ConclusionThe existence of a correlation between the duration of a chronic traumatic event and the persistence of dissociative symptoms in the evolution of a dissociative personality disorder is possible.

Introduction
The personality disorders are defined according to the DSM-5 like “an enduring maladaptive patterns of behavior, cognition and inner experience, exhibited across many contexts and deviating markedly from those accepted by the individual's cultures. These patterns develop in adolescence and the beginning of adulthood, and are associated with significant distress or disability”. The personality disorders can be a risk factor for different processes of the psychiatric pathology like suicide. The personality disorders are classified in 3 groups according to the DSM-5:
– cluster A (strange subjects): paranoid, schizoid and schizotypal;
– cluster B (immature subjects): antisocial, bordeline, histrionic and narcissistic;
– cluster C (frightened subjects): avoidant, dependent and obsessive-compulsive.
AimsTo describe the influence of personality disorders in suicide attempts.
MethodologyExhibition of clinical cases.
ResultsIn this case report, we exhibit three clinical cases of suicide attempts which correspond to a type of personality disorder belonging to each of the three big groups of the DSM-5 classification, specifically the paranoid disorder of the cluster A, the disorder borderline of cluster B and the obsessive compulsive of cluster C.
ConclusionsThe personality disorders have a clear relation with the suicide attempts, increasing this influence in some of them, especially the borderline personality disorder.
