The effect of drug holidays on sexual dysfunction in men treated with selective serotonin reuptake inhibitors (SSRIs) other than fluoxetine: an 8-week open-label randomized clinical trial.

INTRODUCTION: Selective serotonin reuptake inhibitors (SSRIs) are widely used for the treatment of various mental disorders. Sexual dysfunction is one of the most common side effects of SSRIs, and often leads to poor adherence and treatment discontinuation. While several strategies have been employed to manage SSRI-induced sexual dysfunction, drug holidays has not been extensively studied for this purpose. This clinical trial aims to assess the effect of drug holidays on sexual dysfunction in married men under treatment with SSRIs other than fluoxetine (as its long half-life makes drug holidays ineffective). METHODS: This 8-week double-center, randomized, open-label, controlled trial was conducted in the outpatient clinics of Iran Psychiatric Hospital and Tehran Institute of Psychiatry, from January 2022 to March 2023. We included married men aged between18 and 50 years who had experienced sexual dysfunction during treatment with SSRIs, other than fluoxetine. The Male Sexual Health Questionnaire (MSHQ) and the 28-Question General Health Questionnaire (GHQ-28) were used for the assessment of sexual function and mental health status. The drug holidays group was instructed not to take their medications on the weekends. The control group was asked to continue their regular medication regimen without any changes. Both groups were assessed at baseline, and weeks 4 and 8. RESULTS: Sixty-three patients were included and randomly assigned to the drug holidays group (N = 32) or the control group (N = 31). Fifty patients (25 in each group) completed the trial. Drug holidays significantly improved erection, ejaculation, satisfaction, and the overall sexual health of the participants (P < 0.001). No significant change was observed in their mental health status. No major side effects were recorded. CONCLUSIONS: Drug holidays significantly improved the MSHQ scores in 'erection', 'ejaculation', 'satisfaction' and 'total' in married men with sexual dysfunction induced by SSRIs, other than fluoxetine, without causing any significant changes in their mental health status. Further research is needed to reach a certain conclusion. TRIAL REGISTRATION: The trial was registered at the Iranian Registry of Clinical Trials on 2021.10.25 ( www.irct.ir ; IRCT ID: IRCT20170123032145N6) before the trial.

Workshop-based training of pre-hospital emergency technicians for acute psychiatric patients: benefits and drawbacks.

BACKGROUND: Pre-hospital emergency technicians are crucial in managing patients with acute psychiatric symptoms. They must quickly assess the condition, make a primary diagnosis, and refer the patient to the appropriate treatment center. Insufficient skills in these situations can cause serious harm. Educating technicians on dealing with these patients may enhance their knowledge and skills; however, we do not know the extent and longevity of this improvement and which areas are affected. This study investigates the impact of training on pre-hospital emergency technicians' knowledge and skills. METHODS: This quasi-experimental study involved pre-hospital emergency technicians in Robat Karim and Nasim Shahr counties from December 2022 to January 2022. The technicians received workshops on interacting with psychiatric patients. The training topics included the basic principles of coping with a psychiatric patient. They also covered a step-by-step approach to dealing with an aggressive patient, dealing with a patient threatening suicide, managing agitation, managing a patient suffering from panic attacks, and finally dealing with a delirious patient. A pre-test assessed their baseline knowledge and skills, followed by a post-test after training and another test three months later. The test results were analyzed. RESULTS: This study involved forty male participants ranging in age from 25 to 44 and with work experience ranging from five to twenty years. As a result of training in dealing with acute psychiatric patients, technicians developed significant skills and knowledge immediately after training, and these improvements remained significant three months after training. Nevertheless, the correct answers decreased during the three-month follow-up compared to the pre-test. Education was less effective at managing panic, delirium, and agitation. CONCLUSION: In conclusion, technicians' knowledge and skills can be effectively enhanced through training; however, the impact diminishes with time. Theories and practical methods, periodic repetition, and real-world internships are the best ways to maximize training effectiveness.

Agomelatine augmentation of sertraline in the treatment of moderate to severe obsessive-compulsive disorder: a randomized double-blinded placebo-controlled clinical trial.

BACKGROUND: As 40-60% of the patients with obsessive-compulsive disorder (OCD) do not adequately respond to the first-line treatment, finding an effective second-line treatment is required. Our aim was to assess the efficacy and safety of agomelatine (a selective melatonin receptor agonist and a 5-hydroxytryptamine (HT)2 C antagonist) augmentation of sertraline in the treatment of patients with moderate to severe OCD. METHODS: In this 12-week randomized, double-blinded, placebo-controlled, parallel-group clinical trial, 65 patients with moderate to severe OCD according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM-5) criteria and a Yale-Brown obsessive compulsive scale (Y-BOCS) score of over 21, were included. They were assigned with sertraline (100 mg/day for the first 4 weeks and 200 mg/day for the next 8 weeks) and either agomelatine (25 mg/day) or placebo. The primary outcome was OCD symptoms measured by the Y-BOCS. RESULTS: Fifty patients (24 in agomelatine group and 26 in placebo group) completed the trial. The Y-BOCS scores in total (MD (95% CI) = 12.25 (11.00, 13.49) (P < 0.001) vs. MD (95% CI) = 12.46 (6.65, 15.74) (P < 0.001)), the obsession subscale (MD (95% CI) = 5.04 (4.19, 5.88) (P < 0.001) vs. MD (95% CI) = 5.00 (3.84, 6.16) (P = 0.0001)), and compulsion subscale (MD (95% CI) = 7.21 (6.34, 8.07) (P < 0.001) vs. MD (95% CI) = 7.460 (6.50, 8.42) (P < 0.001)) significantly decreased in both groups. Although, at the end of the trial, no significant difference was observed between the scores of the two groups in total (MD (95% CI) = 0.480 (-1.23, 2.19) (P = 0.78)), the obsession subscale (MD (95% CI) = 1.020 (-0.15, 2.19) (P = 0.38)), and the compulsion subscale (MD (95% CI) = 0.540 (-0.34, 1.42) (P = 0.54)). No major adverse effects were recorded, and the frequency of side effects was not significantly different between the groups. CONCLUSION: Agomelatine in augmentation with sertraline is safe and tolerable in patients with moderate to severe OCD. However, our study does not support its efficacy in improving OCD symptoms, compared to placebo. TRIAL REGISTRATION: The trial was registered at the Iranian Registry of Clinical Trials on 14/07/2020 ( www.irct.ir ; IRCT ID: IRCT20170123032145N5).

Higher anxiety and perceived trauma among COVID-19 patients: a prospective comparative study.

BACKGROUND AND PURPOSE: Psychiatric disorders such as anxiety, depression, and traumatic stress are not rare during infectious outbreaks, as the COVID-19 pandemic has posed a great concern to the general population. In this study, we aimed to investigate whether experiencing psychiatric symptoms during COVID-19 is the result of the burden of carrying an illness or the COVID-19 itself. METHOD: Two hundred ten subjects and three different groups of participants (COVID-19 patients, university staff, and orthopedic patients) were recruited. They answered a demographic questionnaire, Yale-Brown Obsessive-Compulsive Scale (YBOCS) test for OCD symptoms, Impact of Event Scale-Revised (IES-R) for perceived trauma, Beck Anxiety Inventory (BAI) for anxiety, and Beck Depression Inventory (BDI) for depression assessments using phone or face-to-face interviews. RESULT: At least one OCD symptom was observed in 85.7% of the subjects. However, there was no significant difference between the 3 groups (p = 0.2194). Perceived trauma was significantly higher among COVID-19 patients followed by university staff and orthopedic patients (23.73, 16.21, 11.51 mean IES-R scores respectively, p = 8.449e-14). COVID-19 patients also showed higher anxiety (mean BAI score: 17.00) than the university staff and orthopedic patients' group (9.22 and 5.56 respectively) (p = 6.175e-08). BDI score did not show much variation for depression, the mean score was 9.66, 9.49, and 6.7 for the COVID-19 patients, university staff, and orthopedic patients respectively, (p = 0.2735). CONCLUSION: Perceived trauma and anxiety symptoms are significantly higher in COVID-19 patients and the symptoms of OCD and depression do not differ between COVID-19 and non-COVID-19 people, so the necessity of screening and following treatment of patients with COVID-19 should be kept in mind. TRIAL REGISTRATION: IR.IUMS.FMD.REC.1399.761.

Limits on using the clock drawing test as a measure to evaluate patients with neurological disorders.

BACKGROUND: The Clock Drawing Test (CDT) is used as a quick-to-conduct test for the diagnosis of dementia and a screening tool for cognitive impairments in neurological disorders. However, the association between the pattern of CDT impairments and the location of brain lesions has been controversial. We examined whether there is an association between the CDT scores and the location of brain lesions using the two available scoring systems. METHOD: One hundred five patients with brain lesions identified by CT scanning were recruited for this study. The Montreal Cognitive Assessment (MoCA) battery including the CDT were administered to all partcipants. To score the CDT, we used a qualitative scoring system devised by Rouleau et al. (1992). For the quantitative scoring system, we adapted the algorithm method used by Mendes-Santos et al. (2015) based on an earlier study by Sunderland et al. (1989). For analyses, a machine learning algorithm was used. RESULTS: Remarkably, 30% of the patients were not detected by the CDT. Quantitative and qualitative errors were categorized into different clusters. The classification algorithm did not differentiate the patients with traumatic brain injury 'TBI' from non-TBI, or the laterality of the lesion. In addition, the classification accuracy for identifying patients with specific lobe lesions was low, except for the parietal lobe with an accuracy of 63%. CONCLUSION: The CDT is not an accurate tool for detecting focal brain lesions. While the CDT still is beneficial for use with patients suspected of having a neurodegenerative disorder, it should be cautiously used with patients with focal neurological disorders.

Memantine augmentation of sertraline in the treatment of symptoms and executive function among patients with obsessive-compulsive disorder: A double-blind placebo-controlled, randomized clinical trial.

BACKGROUND: Medications currently recommended for the treatment of Obsessive-Compulsive Disorder (OCD) usually decrease the severity of the symptoms by 20-30%; however, 40-60% of OCD patients do not achieve a satisfactory response. Our main objective was to investigate the effectiveness of memantine, a non-competitive N-Methyl-D-aspartate (NMDA) receptor antagonist, as an adjunct therapy to sertraline, a selective serotonin reuptake inhibitor (SSRI), to improve severity of symptoms and executive function among patients with obsessive-compulsive disorder. METHODS: Seventy patients with OCD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, and a Yale-Brown obsessive compulsive scale (Y-BOCS) score of more than 21 were recruited to the study. They received sertraline (100 mg daily initially followed by 200 mg daily after week 4) and either memantine (10 mg twice daily) or placebo in a placebo controlled, double-blinded, parallel-group, clinical trial of 12 weeks. The primary outcome was OCD symptoms measured by the Y-BOCS. Moreover, executive function of participants was measured by the Wisconsin Card Sorting Test (WCST). RESULTS: The total score, and obsession and compulsion subscales of Y-BOCS significantly dropped in both groups with no significant difference between the two groups. However, memantine group showed a greater response in the number of completed categories subscale of the WCST (p value<0.001). We did not observe any major adverse effects in any of the groups. CONCLUSION: Memantine has an acceptable safety and tolerability in patients with OCD and might have a positive effect on their executive function. Nevertheless, the current results don`t support the efficacy of memantine as an adjunctive agent to sertraline for symptoms in patients with OCD. TRIAL REGISTRATION: The trial was registered at the Iranian Registry of Clinical Trials on 04/10/2019 ( www.irct.ir ; IRCT ID: IRCT20170123032145N4).

Chronic fatigue syndrome and cognitive deficit are associated with acute-phase neuropsychiatric manifestations of COVID-19: A 9-month follow-up study.

The preva lence of long-COVID symptoms is rising but it is not still possible to predict which patients will present them, and which types of symptoms they will present. We followed up 95 patients with confirmed COVID-19 for 9 months to identify and characterize long-COVID symptoms. Easy fatigability was the most common symptom (51.04%), followed by anxiety (38.54%), dyspnea (38.54%), and new-onset headache (38.54%). There was no association between COVID-19 severity in the acute phase and the number of long-COVID symptoms (F(1,93) = 0.75, p = 0.45), and cognitive function (MoCA) scores (F(1,90) = 0.073, p = 0.787) at follow-up. Being female (F(1,92) = - 2.27, p = 0.02), having a higher number of symptoms (F(1,93) = 2.76, p = 0.0068), and experiencing constitutional neuropsychiatric symptoms (F(1,93) = 2.529, p = 0.01) in the acute phase were associated with having chronic fatigue syndrome at follow-up. Moreover, constitutional neuropsychiatric symptoms in the acute phase were associated with a lower MoCA score (F(1,93) = 10.84, p = 0.001) at follow-up. Specific clinical presentations such as constitutional neuropsychiatric symptoms in the acute phase might be predictors of debilitating long-COVID symptoms such as chronic fatigue syndrome and cognitive deficits.

The Effects of an Empathic Communication Workshop on Internal Medicine Residents' Self-Perceived Empathy and Their Patients' Perception of Physician's Empathy: A Single-Group Experimental Study.

Background: Empathetic communication improves the physician-patient relationship and enhances patient and physician satisfaction. This study aims to evaluate the impact of empathic communication skills training on physicians' self-perceived performance and patient satisfaction regarding the empathetic quality of their relationship with their physicians. Methods: In this single-group before-after experimental study, we recruited 50 internal medicine residents at a large teaching hospital. We assessed the residents' empathy using the Jefferson Scale of Empathy before and 3 weeks after an 8-hour workshop on empathic communication skills. We also recruited 50 of their patients before and another 50 patients 3 weeks after the training to assess the patient's perceptions of their physician's empathy using the Consultation and Relational Empathy scale. Physicians' and patients' mean scores on empathetic care at the beginning of the study were then compared using paired t-tests with their scores after the workshop. Results: The residents' mean score on Jefferson Empathy Scale increased from 81.1(95%CI:78.8-83.3) at baseline to 96.8(95%CI:93.6-100) following the workshop (p < 0.001). Before the empathetic communication skills training, patients assessed their doctors' empathy at 68.3(95%CI:63.5-73.2). After the intervention, this improved to 84.9(95%CI:82.2-87.5) (p < 0.001). Conclusion: In this study, both the residents and their patients stated that the residents' empathy skills had significantly improved after an empathetic communication workshop for internal medicine residents.

Comparison of empathy with patients between first-year and last-year medical students of Tehran University of Medical Sciences.

PURPOSE: This study was conducted to assess the developmental factors of empathy among medical students of Tehran University of Medical Sciences (TUMS). METHODS: To assess the empathy levels, 42 first-year and an equal number of last-year medical students were randomly selected. They answered a questionnaire including the medical student version of the Jefferson Scale, demographic, and some related variables. Statistical analyses were performed using the Chi-square test, T-test, univariate, and multivariate regressions. RESULT: The study population consisted of 51 (60.7 %) men and 33 (39.3 %) women with a mean (SD) age of 22.24 (4.10) years. The Jefferson score was 110.19 ± 13.61 and 103.52 ± 20.00 in first- and last-year medical students, respectively. Moreover, medical students who completely passed at least one of the considered empathy courses of the TUMS curriculum had higher empathy scores compared to their counterparts (109.83 ± 15.54 vs. 103.68 ± 19.02). There was no significant association between empathy and gender, self-experience of illness, marital status, family history of chronic disease, and parents' education (all P-values > 0.05). After adjusting for the effects of confounders, the empathy scores were significantly associated with the academic year level (p = 0.04), level of interest in medicine (p = 0.001), and passing the empathy courses (p = 0.04). CONCLUSIONS: The data provided from a top Iranian medical school indicated that the academic year level, level of interest in medicine, and passing the empathy courses were significantly associated with the empathy level. Further studies are recommended.

Development of a pre-hospital emergencies protocol for the management of suicidal patients in Iran.

BACKGROUND: Suicide is a painful consequence of many psychiatric disorders and one of the most frequent psychiatric emergencies. Generally, pre-hospital technician is the first person in the treatment chain who attends the situation; hence, his/her sound clinical judgment and professional behavior can play an important role in preventing or stopping the suicide process. We tried to develop a concise, evidence-based, and step-by-step guide for dealing with a suicidal patient, which could be quickly reviewed by technicians before confronting a suicide situation. METHOD: We reviewed the literature for suicide management plans and protocols, to extract the evidence-based interventions and instructions for dealing with a suicide situation. Then, we discussed the extracted material in an expert panel, and developed the initial version of the protocol considering the local socio-cultural issues and available facilities. Subsequently, we reviewed the protocol in a meeting with pre-hospital technicians and emergency physicians, to receive their feedback and address any possible executive problems. Finally, we revised the protocol to its final version considering the feedbacks. RESULTS: The basic principles of dealing with a suicidal patient are similar to other psychiatric emergencies and include: Patient Safety; Patient evaluation and diagnosis; and Patient (behavioral and pharmacological) management. However, specific considerations should be taken into account and special arrangements are necessary for suicidal patients. Whether the patient has attempted suicide or not, would guide the management to one of the two major paths. In addition, the needs of the family should be considered. CONCLUSION: A locally adapted protocol considering existing facilities in the emergency system and cultural issues in Iranian society is provided for pre-hospital emergency technicians.

First line in psychiatric emergency: pre-hospital emergency protocol for mental disorders in Iran.

INTRODUCTION: This article is a report of designing a rapid and effective guide for paramedics who take care of patients in a pre-hospital setting to answer developing demands. METHODS: The relevant literature was reviewed, and the topics were extracted. Then, the extracted items were discussed in an expert panel. Finally, items were discussed in a meeting including emergency technicians and emergency technical assistants to identify implementation problems. RESULTS: Important topics for managing psychiatric patients were categorized at three levels: 1) Patient safety and security issues, 2) Patient status assessment and diagnosis, and 3) Patient management (medical, behavioral management, and referral to a treatment center). DISCUSSION: This protocol can be a solution to improve emergency technician training. Such summarized protocols can be used for rapid review immediately before exposing a patient with an acute psychiatric condition. Due to specific cultural and different access to medicines in Iran, some issues are different.

Raphe nuclei echogenicity changes in obsessive-compulsive disorder.

Background: Dysregulation of serotonin system is hypothesized to play the main role in the etiology of obsessive-compulsive disorder (OCD). Transcranial sonography (TCS) is a helpful noninvasive and low-cost tool for the assessment of subcortical brain architectures, mainly basal nuclei, cerebellar central structures, and midbrain. In this study, an ultrasound assessment was performed for a sample of the patients with OCD and healthy control group to evaluate echogenicity of midbrain raphe nuclei (RN). Methods: A total of 35 patients with OCD and 35 healthy controls of similar age and sex entered the study. Semi-structured clinical interview was performed according to the DSM IV-TR criteria to verify OCD. Echogenicity of the midbrain RN was assessed by an experienced neurologist applying TCS. The echogenicity of the 2 groups was compared using chi- square test. SPSS software (version 18, PASW) was used for statistical analysis and p-value of less than 0.05 was considered significant. Results: In this study, 15 OCD patients (42.9%) and 11 (31.4%) controls showed decreased echogenicity of midbrain RN. Also, the results of the chi-square test showed that the midbrain RN echogenicity was not significantly lower in patients with OCD compared to the control group (p= 0.322). Conclusion: Although decreased midbrain RN echogenicity is a characteristic of patients with major depression, it was not shown in OCD patients in this study, which can be explained by the involvement of RN projections rather that RN serotoninergic neurons.

Repetitive transcranial magnetic stimulation of the dorsolateral prefrontal cortex enhances working memory.

Neuroimaging and electrophysiological studies have unequivocally identified the dorsolateral prefrontal cortex (DLPFC) as a crucial structure for top-down control of working memory (WM) processes. By modulating the excitability of neurons in a targeted cortical area, transcranial magnetic stimulation (TMS) offers a unique way to modulate DLPFC function, opening the possibility of WM facilitation. Even though TMS neuromodulation effects over the left DLPFC have successfully improved WM performance in patients with depression and schizophrenia in a multitude of studies, raising the potential of TMS as a safe efficacious treatment for WM deficits, TMS interventions in healthy individuals have produced mixed and inconclusive results. Here, we stimulated the left DLPFC of healthy individuals using a high-frequency repetitive TMS protocol and evaluated behavioral performance in a battery of cognitive tasks. We found that TMS treatment enhanced WM performance in a verbal digit span and a visuospatial 2-back task.

Predictors of physical restraint in a psychiatric emergency setting.

BACKGROUND: Considering the negative consequences of using physical restraints, we conducted this study to identify patients who are more frequently restrained in a psychiatric emergency ward as an initial step to limit the use of restraint to the minimum possible. METHODS: This was a retrospective case control study conducted in Iran Psychiatric Hospital in Tehran, Iran. We reviewed the files of 607 patients who were admitted during a one year period using convenience sampling; of them, 186 were in the restrained group and 421 in the unrestrained group. RESULTS: Surprisingly, no significant difference was found between the restrained and unrestrained groups in demographic characteristics. The patients who were referred because of violence were diagnosed as having methamphetamine induced psychotic disorder or bipolar I disorder in manic 1episode and had a higher odds of being restrained (OR=2.51, OR=1.61, and OR=1.57 respectively). Being restrained was also associated with a longer duration of hospitalization and duration of staying in the emergency ward. Moreover, patients in their first admission were more frequently restrained. CONCLUSION: Medical and nursing staff should consider special measures for the patients who are at a higher risk for being restrained. More frequent visits and education for both patients and staff may be effective in reducing the number of physical restraints for these groups of patients.

A pilot randomized controlled trial on the effectiveness of inclusion of a distant learning component into empathy training.

BACKGROUND: Studies have shown a gradual decline in empathy of medical trainees with increasing years of education. METHODS to augment empathy show some promise, but the most effective methods are both expensive and time consuming. To assess effectiveness of communication skills training program as a distant learning method in improving empathy. METHODS: Fourteen first year residents of psychiatry were randomly allocated to either participate in a two day workshop on communications skills (attending group) or to watch the videotape of the first day and participate in the second day (distance learning group). Assessments included Jefferson Scale of Empathy (JSE) and objective assessment of empathy (OAE) during a simulated interview, before and 3 months after the training. RESULTS: The empathy was significantly increased in the attending group as measured by OAE. The score of JSE also increased in the attending group but did not reach a significance level. No increase in empathy was seen in the distance learning group. CONCLUSION: Watching the videotape of the workshop is not effective in improving empathy of residents. More interactive methods should be sought if we plan to use distance learning methods in enhancement of empathy.

The burden of traumatic brain injury on caregivers: exploring the predictive factors in a multi-centric study.

BACKGROUND: Traumatic brain injury (TBI) is a significant cause of mortality and morbidity worldwide. With survivors often exhibiting degrees of function loss, a significant burden is exerted on their caregivers. The purpose of this study was to explore the predictive factors of caregiver burden among caregivers of patients with TBI. METHODS: Sixty-eight family members of individuals with a TBI who had been admitted to three hospitals were assessed in terms of caregiver burden using the Zarit Burden Interview. The association of caregiver burden with patients' baseline cognitive function according to the Montreal Cognitive Assessment (MoCA) test, as well as caregivers' sociodemographic characteristics, were evaluated using multiple regression analysis. RESULTS: Based on the multiple regression model, the MoCA score of the patients (std ß=-0.442, p < 0.001), duration of caregiving (std ß = 0.228, p = 0.044), and higher education of the caregivers (std ß = 0.229, p = 0.038) were significant predictors of caregiver burden. CONCLUSION: Overall, our findings highlight the importance of taking caregivers' psychosocial needs into account. Long-term caregivers of TBI patients with cognitive impairment should be viewed as vulnerable individuals who could benefit from psychosocial intervention programs, to improve their well-being and enabling them to enrich their care of the TBI patient.

Mania precipitated by opioid withdrawal: a retrospective study.

OBJECTIVE: Little evidence is available on the occurrence of mania following opioid withdrawal. This is the first report on clinical and demographic characteristics of mania precipitated by opioid withdrawal in a relatively large sample. METHOD: In this study, we assessed the files of the patients admitted to a large referral psychiatric hospital during a 3-year period with a presentation of manic episode shortly after opioid withdrawal. Forty-five relevant cases (one woman) were found, including 28 patients with their first manic episode, and 17 patients with a previous history of bipolar disorder. RESULTS: Most of the identified cases had a long history (mean = 11.8 years) of opium dependence (24 cases used only opium and 16 cases opium and other opioids) and had recently experienced an intense withdrawal (25 cases). These associations were present in both first-episode patients and those with recurrent episodes. CONCLUSION: Emergence of mania following opioid withdrawal could be partly explained by mood stabilizing effects of opioids. Other than the type of opioid, it seems that the duration of use and withdrawal method might play a role. Caution should be used while detoxifying patients with a long history of opioid use.

Empathy in Iranian medical students: measurement model of the Jefferson scale of empathy.

BACKGROUND: Empathy is an important factor in patient-physician relationship that has beneficial effects in medical practice. Jefferson scale of empathy (JSE) has been specifically designed to assess empathy in health professionals (HP-version) and related students (S-version). Few validation studies have been performed on S-version of the scale. AIMS: To examine empathy in a large sample of Iranian medical students, and also to study factor structure and psychometric properties of the Persian translation of the S-version of the JSE. METHOD: 1187 medical students (759 female) from 16 universities around the country participated in the study during 2009. Independent sample t-test, multivariate analysis of variance, and confirmatory factor analysis (CFA) were performed to analyze the data. RESULTS: Female students outscored male students in empathy. The trend for empathy had a negative relationship with years of education. JSE showed an acceptable internal consistency and test re-test reliability. CFA upheld the original three-factor structure--Perspective taking, compassionate care, and standing in the patient's shoes--consisting 20 items. CONCLUSION: The decrease in empathy during medical education is consistent with previous studies. The Persian version of JSE is a valid and reliable measure to tap empathy in a Persian-speaking medical student.

Clinical features of inpatients with methamphetamine-induced psychosis.

BACKGROUND: An epidemic of methamphetamine use has begun in Iran in recent years and psychiatric emergency services are overloaded with patients with methamphetamine-induced psychosis (MIP). AIMS: To define the clinical features of inpatients with MIP in a psychiatric hospital. METHOD: The files of all MIP patients admitted to Iran Psychiatric Hospital located in Tehran from April 2008 to April 2010 were assessed. Data related to psychotic episode, substance use, previous psychiatric history and demographic data of 111 MIP patients were extracted and analyzed using descriptive statistical methods. RESULTS: The most prevalent psychotic symptoms were persecutory delusion (82%), auditory hallucination (70.3%), reference delusion (57.7%), visual hallucination (44.1%), grandiosity delusion (39.6%) and jealousy delusion (26.1%). The mean duration of admission and psychotic episode was 21.43 and 17.37 days, respectively. In seven cases (8.75%), symptoms continued for more than one month. CONCLUSION: Frequency of psychotic symptoms in this study is relatively similar to previous studies. However, some clinical determinants such as latency of psychosis from first use and the course of psychosis are more similar to the first epidemic of methamphetamine in Japan than to more recent epidemics; which could be due to the short history of methamphetamine use in Iran.
