Only 21% of patients included in the South of Granada's First Episodes Program in the year 2014 were women. Studies do not use to focus on sex differences at first-episode samples and it can be masking some relevant variables in this population.

In this exploratory study, we aim to focus on gynaecological consultations during the period of untreated psychosis (DUP) at first episodes of psychosis in women.

A retrospective clinical-cases review of medical histories was made searching for sociodemographic variables, consultations during DUP and psychotic prodromal outcomes.

The average age of the sample was 23 years. The average of DUP was one to three months. Sixty percent of referees to mental health services were from primary care and 20% from emergency services. The main symptom was persecutory or prejudice delusions. Thirty-six percent of them were related to sexuality or pregnancy. In most cases, the demands were not bizarre. When a wide history was made and they were properly explored, a delusional theme was appreciated and the reason for consultation was not justified. Eg. Postcoital pill order for not taking precautions, in a telepathic relationship. Forty percent of claims were made in primary care. Half of them were assessed by a gynecologyst. Sixty percent were treated in the emergency room.

We conclude that these data are relevant for specialists. Both for efficient resource management and for early detection of incipient psychosis. Gynecological abnormal demands are common in consultations to health services for specific malaise during the period of untreated psychosis.

There are many jobs that offer advantages of treatment with long-acting injectable in psychosis.

To know the changes in the different variables after the start of paliperidone palmitate (PP).

We performed a descriptive and retrospective study. Were evaluated patients who received maintenance therapy with PP during 48 months.

The sample was composed of 29 patients: 72.4% men and 27.6% women. Average age of 46.21 years. In Figures 1, 2 and 3 show data obtained in relation to compliance with treatment, relapse, maintenance dose, number of admissions and visits to emergency departments respectively.

The administration of PP is associated with a higher level of compliance with treatment. The patients presented a lower number of relapses, hospitalizations and visits to the emergency room. The maintenance dose more used is 150 mg.

Both 1st and 2nd generation of antipsychotics are associated with prolonged QTc interval. Prolonged QTc can lead to ventricular tachycardia and Torsade's de pointes, ultimatime resulting to cardiac arrest and sudden death. Prolonged QTc interval due to increased DDD has not yet been investigated.

To investigate whether increased DDD of antipsychotics, causes further prolonged QTc, by patients diagnosed with schizophrenia.

To learn more about antipsychotics impact on the QTc interval in patients diagnosed with schizophrenia.

An observational study of unselected patients diagnosed with schizophrenia. Enrolled from January 2013 through March 2015 with follow-up until June 2015 in the region of central Denmark. Data was collected from ECG records and patient journals.

ECGs were available in 58 patients. We observed no relation between increased DDD of antipsychotics and prolonged QTc. There were no differences in average QTc interval for the whole sample of patients receiving different DDD of antipsychotics.

We do not recommend increased attention to patients treated with higher DDD of antipsychotics.

Recent evidence points to a critical role of redox dysregulation induced oxidative stress in the pathophysiology of early phases of schizophrenia. An add-on trial with n-acetyl-cysteine (NAC) led to a reduction in negative symptoms in chronic schizophrenia patients. Aim of this study was to explore impact of addition of NAC to standard treatment in early psychosis (EP) patients.

Double-blind, randomized, placebo-controlled trial of addition of NAC, 2700 mg daily, to antipsychotic treatment over 6 months. Monthly assessment of PANSS, GAF, SOFAS and antipsychotics treatment; quantification of brain glutathione levels (GSHmPFC) by 1H-magnetic-resonance-spectroscopy and of blood cells glutathione (GSHBC) and glutathione peroxidase activity (GPxBC) as marker of oxidation status at the beginning and end of treatment.

Overall, 63 patients were included. Spectroscopy data showed that GSHmPFC increased by +23% in the NAC group, while it tended to decrease by −5% in the placebo group (P = 0.005). No significant difference between NAC and placebo was observed on global changes in negative symptoms, positive symptoms or functional outcome. However, in patients with high-baseline oxidation status (GPxBC>22.3U/gHb), subgroup explorations revealed an improvement of positive symptoms over time compared to patients with low-baseline GPx (P = 0.02).

While addition of NAC induced an increase of brain GSH, it had no impact on symptomatic and functional outcome in EP patients. However, in patients with high oxidation status, addition of NAC leads to significantly greater improvement in positive symptoms. Future studies on antioxidant interventions in EP should consider biomarker-guided treatment.

Peripersonal space has been defined as the area immediately surrounding the body in which interactions with a person or an object can occur. Larger peripersonal space may reflect discomfort in close interpersonal situation or cognitive deficit. Individuals with schizophrenia are more sensitive to social stimulation. The capacity to provide accurate judgments of peripersonal space boundaries depend on the capacity to create an organized and structured mental representation that integrates signals from different sensory modalities and brain regions.

We conducted a study on personal space in patients with schizophrenia using a paradigm that was not affected by emotional and social interference.

We aimed to investigate the characteristics of personal space in patients with schizophrenia.

We recruited 20 schizophrenic patients according to DSM-V criterion and 20 healthy volunteers, matched by gender and age. Schizophrenic symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS). Participants performed the peripersonal space (PPS) task. Collected data underwent statistical analyses.

Schizophrenic patients demonstrate a stronger/weaker need for personal space, than the comparison group, depending on the score of negative and positive symptom, as assessed by using the PANSS even without emotional and social interference.

Interpersonal interactions between the individual with schizophrenia and people in their immediate environment can lead to increased symptomatology. Social isolation is one of the most primary causes of poor quality of life in mental illnesses. Better understanding of the mechanisms for abnormal interactive behavior could provide significant valid guidelines for innovating intervention programs.

There is growing evidence about the importance of motor symptoms in psychosis. Motor abnormalities have been observed in naive-drugs, first-episode patients. Clinical assessment of motor abnormalities normally relies upon subjective observer-based ratings. Kinematic analysis of handwriting has proved to be an objective measure of motor symptoms, but it has not been used in clinical settings.

In the present work, the geometrical analysis of handwriting patterns is proposed as a new tool to evaluate motor symptoms in psychosis.

Overall, 35 healthy participants and 43 patients with psychosis from San Agustín Hospital (Linares, Spain) participed in the study. Participants were asked to write with a pen on a white paper (see patterns in the Figure 1). In order to analyze the heterogeneity of handwriting pattterns, we employed lacunarity, a nonlinear measure previously used in the analysis of biomedical images. Lacunarity measures the distribution of gap sizes in a geometrical space. A large value implies large gaps and clumping of points, whereas a small value suggests a uniform distribution with shorter gaps.

Lacunarity was significantly higher in handwritten patterns from patients than in controls. In addition, we found a higher heterogeneity in patients with motor symptoms in comparison with patients without motor symptoms.

Our results suggest that analysis of handwritten patterns can be a valuable method in the evaluation of motor symptoms.

Schizophrenia is a serious disorder that influences all life aspects of the patients. The most important goals in schizophrenia are remission, recovery, improving psychosocial functioning and quality of life, which can be influenced by different factors, especially insight.

To evaluate the awareness of illness in Romanian patients diagnosed with schizophrenia and to determine the predictive role of insight.

This study wants to highlight the importance of the evaluation of insight in psychotic patients, taking into account that awareness leads to compliance with treatment, decreased rate of relapses and rehospitalization and a better prognosis.

Overall, 80 patients (44 males and 36 females) recruited from first and second psychiatric clinic Cluj-Napoca, diagnosed according to ICD-10 and DSM-V criteria with schizophrenia and acute psychotic disorder participated in this study. A semi-structured interview collected demographical data. Psychotic symptoms were evaluated using PANSS, severity of the disease using CGI and insight using SUMD.

Our results showed that the most important predictive factors for the evolution were: level of insight (r = −0.41 P < 0.01), presence of family history (r = 0.24 P < 0.05) and belonging to urban areas (r = 0.23 P < 0.05). The level of insight explained 16% of variance of improving psychotic symptoms during hospitalization.

The awareness of illness is one of the predictive factors for long-term schizophrenia and the best predictive model of disease progression is composed of variables SUMD total and PANSS total on admission.

The dimensional approaches regard delusions as a continuum of the daily beliefs, not being limited to the clinical population and it can also be found in the general population. Due to the multifaceted conceptualization of delusions, the analysis of the dimensions of distress, preoccupation and conviction may be more revealing than the content of the belief itself, whereby an evaluation that incorporates these dimensions is fundamental.

Translation, adaptation and study of the psychometric properties of the Peters et al. delusions inventory (PDI-21) for the Portuguese population.

Assessing the multidimensionality of the delusional ideation in the community.

The sample consists of 249 adults from the general population, aged between 18 to 65. The brief symptom inventory, the social desirability scale of the eysenck personality questionnaire and the World Health Organization quality of life–bref were used in this study beyond the PDI-21.

The Portuguese version of the PDI-21 has shown good psychometric properties regarding its internal consistency and test-retest reliability. It demonstrated significant positive correlations with the psychopathological symptoms and negative associations with social desirability and with the quality of life, confirming its divergent and convergent validity. The analysis of the frequency of delusional ideas for the total of the sample and on the basis of gender has revealed prevalence rates very similar to the ones found in previous studies.

The Portuguese version of the PDI-21 has adequate psychometric properties and it can be used to assess the delusional ideation in the general population.

Although there is no cure, schizophrenia is highly treatable disease. Successful first episode schizophrenia (FES) treatment is crucial to minimize personal, vocational and social deterioration. Quetiapine is atypical, second generation antipsychotic, serotonin-dopamine antagonist. Quetiapine is potent blocker of D2, 5HT2A and 5HT1A receptors.

To estimate efficacy of quetiapine in treatment of first episode schizophrenia.

This study included 70 patients with FES diagnosed by ICD-10 criteria, who are divided into haloperidol (H) 35 patients and quetiapine (Q) group 35 patients. Patients were observed for 6 months in hospital and extra hospital conditions, according to protocol which included Positive and Negative Symptom Schedule Scale (PANSS) and the number of withdrawals attributed to adverse event (AE). Control group was treated with haloperidol 5–20 mg/24 h and experimental group was treated with quetiapine 400–800 mg/24 h.

Average pretrial PANSS score was 110.1 in quetiapine and 108.5 in haloperidol group. Average PANSS score after 180 days was 50.6 in Q and 60.4 in H group. There is no statistical difference in pretrial scores between groups for PANSS score (P = 0.647). There is significant statistical difference in PANSS score reduction after 180 days in both groups (P < 0.001). There is significant statistical difference in PANSS score reduction between Q and H group after 180 days (P < 0.001). Overall, 8.6% AEs occurred in Q, and 25.8% in H group.

Quetiapine has shown better efficacy in treatment of FES comparing to haloperidol, with statistically significant lower adverse effects rate.

Methods of assessment of medicated compliance are based upon preceding experience of taking therapy and cannot be applied at the first admission.

To investigate premorbid characteristics in schizophrenic patients and reveal the factors indicating noncompliance.

We used medical record background, interview, Medical Compliance Prediction Scale for Psychiatry for evaluation of the level of compliance, program STATISTICA10 for identification of the average level of compliance in the subgroups of each factor by Kruskal–Wallis test and revealing those subgroups for each factor where the average level of compliance was statistically significantly lower (P < 0.05).

We examined 120 patients (status corresponded to the ICD-10 diagnostic criteria for schizophrenia, age–18 and older, duration of the disease–5 years and more, patients taking typical or atypical antipsychotics or combined therapy) according to factors of premorbid period such as gender, family history of mental disorders, personality traits, nurture in the family, education level, marital status; substance use, age at the onset of disease.

Level of compliance was lower in subgroups of men, patients having several relatives with mental disorders, patients having personality with predominance of irritable and impulsive traits, patients with neglect in parental families, patients with education level lower than high school and with education level higher than bachelor; patients not working or studying to onset of disease; patients who were divorced or widowed; patients living alone; patients using psychoactive substances; patients aged 21 years and older to the onset of disease.

The basic role of cerebellar dysfunctions in schizophrenia pathophysiology is already well-known. Importantly, cerebellar signs such as gait and balance coordination deficits are objectively manifested and measurable. However, both early detection and treatment monitoring of the illness are still-based mainly on subjective psychopathological symptoms.

To introduce an objective and quantitative approach to the cerebellar gait and balance disorders in schizophrenia.

An original (internationally patented) method for objective equilibriometric quantification of stepping locomotion (a kind of motion analysis system) was developed and then applied repetitively in 230 schizophrenic patients and 230 well-matched healthy controls.

Subclinical but objectively measurable equilibriometric locomotor ataxia (ELA) was identified in a large proportion of the investigated patients. Its severity fluctuated along with the changes in the clinical state. As a rule, the degree of ELA transiently increases during psychotic exacerbation and gradually returns to its prepsychotic level during therapeutic remission. Data analysis revealed that the basic (prepsychotic and postpsychotic) ELA could be viewed as a new schizotaxic biomarker (trait-marker) for schizophrenia, while the degree of its severity could serve as a new objectively measurable state-marker for psychosis. Besides, its dynamics during antipsychotic treatment might be used as an objective measure of the therapeutic response (a kind of surrogate pharmacodynamic biomarker).

Objective quantification of the ELA allows for early detection of subclinical signs of cerebellar ataxia (or schizotaxia) in individuals at high-risk for schizophrenia, whereas in psychotic patients it permits their objective antipsychotic-treatment monitoring.

Incidence of crime victimization and perpetration is higher in severely mentally ill people than in general population. In the literature, fewer papers investigate the risk of being a victim than the risk of perpetrating violence in psychiatric patients.

To study incidence of self-reported crime victimisation or perpetration in 2 multicentric database of patients suffering from schizophrenia or related psychoses who are admitted involuntarily to hospital.

Included involuntarily admitted patients with ICD-10 diagnosis of F20-F29, age 18–65, giving informed consent. Univariable and multivariable logistic regression to estimate odds ratios. Structured interview and BPRS by trained operators.

Three hundred and eighty-three and 543 cases for each database. Victims: 37.8% and 28.0%. Accused: 25.6% and 11.6%. Victims had higher BPRS subscale of Mania, were unemployed and had fewer social contacts. Accused had higher mania in one of the 2 sample. Sociodemographic predictors included unemployment and homelessness, younger age and male gender.

Sociodemographic factors are important predictors of being accused of a crime. Higher symptoms of mania are associated with higher odds of being victim of violence in 2 multicentric samples, after correction for other variables. Rates of both victimisation and perpetration rates are higher than in samples of people from general population or from outpatients settings. Accused and victims have a strong association with consideration on the context of life.

Despite multiple clinical and preclinical studies investigating schizophrenia, the neurobiological basis of this disease is still unknown. The dysregulation of the serotonergic system, in particular the 5-HT2A receptor and the endocannabinoid system have been postulated as possible causes of schizophrenia.

The aim of this study is to evaluate the expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium in schizophrenia patients and control subjects.

We recruited a group of 10 healthy volunteers and 10 patients diagnosed with schizophrenia, who were treated with atypical antipsychotics, were clinically stable and had an illness duration range from 1 up to 15 years. The patients were diagnosed with schizophrenia from the medical record and confirmed by the structured clinical interview for DSM disorders. The expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium was quantified using proximity ligation assays and confocal microscopy.

Olfactory epithelium pro-neurons were viable and expressed the neuronal marker, III-β tubulin. We also established the presence and the functionality of CB1-5-HT2A receptor heteromers in these cells using the proximity ligation and cAMP activity assays, respectively. Heteromer expression was significantly increased in schizophrenia patients with respect to controls.

This highly innovative methodology will allow the noninvasive, low-cost study of new biomarkers for schizophrenia in a model closely related to the central nervous system.

Several scientific studies support the relation between pulmonary embolism and antipsychotic treatment (acute or chronic). We present a case of possible association of venous thromboembolism (VTE) and ziprasidone.

Man, 55-year-old, with mild hypertension. He has neither toxics habits nor allergies. He does exercise every day. He started with behavioral and perception disorders during 9 months before being diagnosed of paranoid schizophrenia in 2002. He began with risperidone 3 mg per day and amisulpride 25 mg per day as hypnotic. It allowed a good development and he keeps stable since then. The treatment produced sedation and weight increase, so it was changed to ziprasidone 60 mg per day and later 40 mg per day. A few months ago, he was hospitalized with breathelessness that started suddenly two days before. After all diagnostic tests, he was diagnosed with pulmonary embolism and right leg VTE. His medical development was very positive and he must begin with acenocumarol (doses–depend) and support stockings.

As we know, since last 10 years, antipsychotic exposure significantly increases the risk of pulmonary embolism. Due to the lack of risk related factor in this case, it would point that reason. The increase related is about 50% of developing VTE and this increased risk similarly applies to first and second generation antipsychotics drugs. Despite that, there are more cases in olanzapine, clozapine and haloperidol treatments due to antiaggregatory action and antithrombotic effects. We present this case probably closely related with ziprasidone.

It is well known about relation between skin and mind, not only due to their mutual origin, but also by their illness expression parallelism. We report a case to show that reciprocity.

Woman, 42-year-old, single. She only suffers from a skin disease; mild psoriasis guttata placed in both elbows and knees. She treated it with local treatment (cortisone cream) during seasonal prutius and the lesions did not grow or expand. She was hospitalized due to psychotic symptoms (paranoid delusions with her colleagues) and started antipsychotics treatment (risperidone 12 mg per day and olanzapine 10 mg per night). By the same time, she suffered a psoriasis crisis. Her psoriatic plaques increased their sizes and her chest and both thighs were affected too. She complained about grave pruritus. All her medical test results were normal. After that, the patient improved her psychotics’ symptoms, but she started with agoraphobic signs and seclusion at home. Psoriasis were even worse than before and she needed metrotexate to treat it. Being introduced to escitalopram 15 mg per day, anxiety and depression symptoms disappeared and her grave psoriasis became the mild one that she knew.

Schizophrenia was associated with a greater variety of autoimmune diseases than was anticipated. Studies found evidence for a shared genetic etiology between schizophrenia and psoriasis. Despite that, we think that the study of psychopathology can amplify our understanding about the etiopathogenesis of psoriasis and associated mental disorders.
