Clinical and biological correlates of optical coherence tomography findings in schizophrenia

There is a growing body of evidence indicating retinal layer thinning in schizophrenia. However, neuropathological processes underlying these retinal structural changes and its clinical correlates are yet to be known. Here, we aim to investigate the clinical and biological correlates of OCT findings in schizophrenia. 50 schizophrenia patients and 40 healthy controls were recruited. Retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), and macular and choroidal thicknesses were recorded. A comprehensive battery of neuropsychological tests was applied. Fasting glucose, triglycerides and HDL-cholesterol levels, TNF-α, IL-1β and IL-6 levels were measured. Right IPL was significantly thinner in patients than the controls after controlling for various confounders (F = 5.42, p = .02). Higher IL-6, IL-1β, and TNF-α levels were associated with decreased left macular thickness (r =  - 0.26, p = .027, r =  - 0.30, p = 0.012, and r =  - 0.24, p = .046, respectively) and higher IL-6 was associated with thinning of right IPL (r =  - 0.27, p = 0.023) and left choroid (r =  - 0.23, p = .044) in the overall sample. Thinning of right IPL and left macula were also associated with worse executive functioning (r = 0.37, p = 0.004 and r = 0.33, p = 0.009) and attention (r = 0.31, p = 0.018 and r = 0.30, p = 0.025). In patients with schizophrenia, IPL thinning was associated with increased BMI (r =  - 0.44, p = 0.009) and decreased HDL levels (r = 0.43, p = 0.021). Decreased TNF-α level was related to IPL thinning, especially in the left eye (r = 0.40, p = 0.022). These findings support the hypothesis that OCT might provide the opportunity to establish an accessible and non-invasive probe of brain pathology in schizophrenia and related disorders. However, future studies investigating retinal structural changes as a biological marker for schizophrenia should also consider the metabolic state of the subjects.

COVID-19 infection, vaccine status, and avoidance behaviors in adults with attention deficit and hyperactivity disorder: A cross-sectional study

Objective

We aim to examine infection risk and vaccine status of COVID-19 in attention deficit and hyperactivity disorder and evaluate the impact of demographic, clinical, and COVID-19-related factors on the infection status and behavioral avoidance of COVID-19.

Methods

This cross-sectional study assessed adults with attention deficit and hyperactivity disorder recruited from an outpatient psychiatry clinic. Patients and healthy controls completed a survey on sociodemographic data, COVID-19 infection status, and vaccine status. COVID-19 Disease Perception Scale, COVID-19 Avoidance Attitudes Scale, Attitudes toward COVID-19 Vaccine Scale, Adult Attention Deficit and Hyperactivity Disorder Self-report Screening Scale for DSM-5, Adult Attention Deficit and Hyperactivity Disorder Self-Report Scale Symptoms Checklist, Patient Health Questionnaire-9, and State-Trait Anxiety Inventory were applied.

Results

Ninety patients and 40 healthy controls participated. Patients did not differ from controls in COVID-19 infection and vaccine status, and behavioral avoidance of COVID-19. No demographic and clinical factor significantly affected the COVID-19 infection status. Patients scored higher than controls in the perception of COVID-19 as contagious (p = 0.038), cognitive avoidance of COVID-19 (p = 0.008), and positive attitudes toward the COVID-19 vaccine (p = 0.024). After adjustment of possible factors, a positive perception of the COVID-19 vaccine and a perception of COVID-19 as dangerous were the two factors significantly affecting behavioral avoidance of COVID-19 [R 2 = 0. 17, F(2) = 13.189, p < 0.0001].

Conclusion

Infection and vaccine status of COVID-19 in patients did not significantly differ from controls. No demographic and clinical factor significantly affected the COVID-19 infection status. Approximately four-fifths of the patients were fully vaccinated as recommended by national and global health organizations. This has increased the knowledge base showing that the COVID-19 vaccine is acceptable and receiving the vaccine is endorsed by ADHD patients. Attention deficit and hyperactivity disorder itself may provoke no kind of mental disturbance in sense of perception of the danger of this disease. Our findings have increased the knowledge base showing that the COVID-19 vaccine is acceptable and the actual practice of receiving the vaccine is endorsed in this population. Our message for practice would be to take into account not only the core symptoms and the comorbidities of the disorder but also the perception of the disease while exploring its link with COVID-19.

The relation of optical coherence tomography findings with oxidative stress parameters in patients with bipolar disorder and unaffected first-degree relatives

BACKGROUND

We aimed to evaluate the optical coherence tomography(OCT) findings and oxidative stress parameters in patients with bipolar disorder(BD) and their unaffected first-degree relatives(FDRs) and to explore OCT findings and oxidative stress parameters as potential endophenotype candidates.

METHODS

Fifty patients with BD, 40 FDRs of BD, and 50 healthy controls(HCs) were included. OCT was performed to measure peripapillary retinal nerve fiber layer(RNFL), ganglion cell layer(GCL), inner plexiform layer(IPL), central macular, and minimum foveal thicknesses(CMT and MFT), choroidal thickness(ChT). 4-hydroxy-2-nonenal(HNE), total thiol(TT), native thiol(NT), total oxidant status(TOS), total antioxidant status(TAS), disulfide(DIS) and oxidative stress index(OSI) were measured from serum samples.

RESULTS

TOS was higher patients with BD and FDRs than HCs (p < .001 and p = .012, respectively). OSI, DIS, HNE levels were higher patients with BD and FDRs than HCs (p < .001). TAS, TT, NT levels were lower patients and FDRs than HCs (p < .001). MFT of patients was thinner than HCs (p = .001). CMT of patients was thinner than HCs (p = .006); the same trend was observed in FDRs but did not reach the statistical significance level (p = .07). The groups did not differ on RNFL and choroidal thickness or GCL and IPL volume.

LIMITATIONS

Evaluation of only a few retinal layers.

CONCLUSIONS

TOS, TAS, OSI, TT, NT, DIS, HNE can be useful endophenotype biomarkers in BD. Among the OCT findings, CMT was determined as the closest parameter to being an endophenotype biomarker. Our study corroborates that oxidative stress parameters are more effective than OCT findings in endophenotype studies.

Oxidative stress and schizophrenia: A comparative cross-sectional study of multiple oxidative markers in patients and their first-degree relatives

OBJECTIVE

Schizophrenia (SCZ) is a chronic, disruptive mental disorder with unknown pathogenic mechanisms. Several studies evidenced that oxidative stress (OS) may be one of the causal factors to play a role in the pathophysiology of the disease. Our study aims to contribute to the SCZ research by investigating a possible relationship between the severity of illness (scored with "The Positive and Negative Syndrome Scale [PANSS]") and OS biomarkers in patients. We additionally assess the "first-degree-relatives (FDRs)" oxidative status with multiple parameters to test the idea of oxidative imbalance leads to disease progression as a genetical susceptibility factor.

METHODS

This study included: 50 adult patients with SCZ, 50 unaffected FDRs, and 50 controls. OS biomarkers included myeloperoxidase (MPO), total oxidant status (TOS), total antioxidant status (TAS), total thiol (TT), native thiol (NT). Photometric methods were used to measure the parameters in the peripheral blood samples of participants. Disulphide (DS) and oxidative stress index (OSI) parameters were calculated.

RESULTS

TOS, DS, OSI levels were significantly higher, and TAS, TT, NT levels were significantly lower in both SCZ and FDRs than controls. In the SCZ group, MPO activity was significantly higher compared with other groups. Results in this study did not provide a strong correlation between the PANSS and selected biomarkers. There was a slightly negative correlation between TT and PANSS in the SCZ group (P = .041, r = -.297).

CONCLUSION

OS biomarkers increased significantly in the peripheral blood of SCZ patients compared with other groups indicates the presence of OS in the aetiology of the disease. Mid-levels of oxidative markers found in FDRs imply that unaffected first-degree relatives have an increased risk for turning up to the clinical presentation stage.

A Treatment-Response Comparison Study of Resting-State Functional Magnetic Resonance Imaging Between Standard Treatment of SSRI and Standard Treatment of SSRI Plus Non-dominant Hand-Writing Task in Patients With Major Depressive Disorder

Background: Researches have recently shifted from functional/structural imaging studies to functional connectivity (FC) studies in major depressive disorder (MDD). We aimed to compare treatment response of two treatment groups before and after treatment, in terms of both with psychiatric evaluation scales and resting-state functional connectivity (RSFC) changes in order to objectively demonstrate the possible contribution of the non-dominant hand-writing exercise (NHE) effect on depression treatment. Methods: A total of 26 patients who were right-handed women with similar sociodemographic characteristics were enrolled. Their pre-treatment resting-state functional magnetic resonance imaging (rs-fMRI) and neuropsychiatric tests were recorded, and then, patients were divided into two groups randomly. A standard treatment (ST) (fix sertraline 50 mg/day) was given to both groups. One randomly selected group was given the NHE in addition to the ST. After 8 weeks of treatment, all patients were reevaluated with rs-fMRI and neuropsychiatric tests. Pre- and post-treatment FC changes within the groups and post-treatment connectivity changes between groups were evaluated. Results: Post-treatment neuropsychiatric tests were significantly different in both groups. Post-treatment, two brain regions' connectivity changed in the ST group, whereas 10 brain regions' connectivity changed significantly in the ST + NHE group. When treatment groups were compared with each other after the treatment, the FC of 13 regions changed in the ST + NHE group compared to the ST group (p-unc/p-PFD <0.05). The density of connectivity changes in the frontal and limbic regions, especially connectivities shown to change in depression treatment, in the ST + NHE group indicates a positive contribution to depression treatment, which is also supported by neuropsychiatric scale changes. Conclusion: NHE, which we developed with inspiration from the Eye Movement Desensitization and Reprocessing (EMDR) method, showed significantly more connecitivity changes related with MDD treatment. Beyond offering a new additional treatment method, our study will also contribute to the current literature with our efforts to evaluate all brain regions and networks that may be related to MDD and its treatment together, without being limited to a few regions. Trial Registration: The rs-fMRI and treatment registers were recorded in the BizMed system, which is the patient registration system of Bezmialem Vakif University Medicine Faculty, under the BAP support project approval code and the registration number 3.2018/8.

Eating disorders in patients with irritable bowel syndrome

INTRODUCTION

Eating disorders (ED) constitute an important group of conditions that commonly occur in adolescents. Gastrointestinal complaints are frequently reported in ED patients. Few studies assessed the association of irritable bowel syndrome (IBS) with ED. The aim of the current study is to determine the prevalence of ED in a group of IBS patients and compare it with a healthy control group and assess the relationship of IBS sub-types, it's duration and severity with ED.

PATIENTS AND METHODS

100 IBS patients diagnosed according to the Rome-IV criteria and a control group consisting of 100 healthy adults, between 18 and 65 years old, were enrolled in this study. Sub-type, duration and severity of IBS were determined. All participants were requested to fill questionnaires to screen for ED.

RESULTS

200 subjects participated in the study. 118(59%) were female and 92(41%) were male. The Eating Attitudes Test (EAT) score was significantly higher in the IBS group (Odds ratio: 5.3 CI 95%:4.3-9.3; p<0.001). The number of subjects with EAT score >30 was significantly higher in the IBS group (p<0.001). EAT scores were significantly higher in female IBS patients and in younger patients (p=0.013 and p=0.043; respectively). No significant association between the IBS sub-type and EAT score was found (p>0.05). However, IBS severity and duration positively correlated with EAT scores.

DISCUSSION

ED should be considered in the management of IBS patients. Since many psychological factors can exacerbate IBS symptoms a multidisciplinary approach consisting of medical and behavioral therapeutic modalities should be employed for a better management of these patients.

The effects of atypical antipsychotic usage duration on serum adiponectin levels and other metabolic parameters

OBJECTIVE

Although atypical antipsychotics are well-tolerated and effective treatment options for schizophrenia, they have metabolic side effects, including weight gain and increased risk of Type II Diabetes Mellitus (DM). Adiponectin, produced exclusively in adipocytes, is the most abundant serum adipokine. Low levels of adiponectin are correlated with DM, insulin resistance and coronary heart disease. Usage of atypical antipsychotics may create a risk of metabolic syndrome. The aim of this study was to evaluate the effects of antipsychotic usage on parameters related to development of metabolic syndrome.

MATERIALS AND METHODS

A total of 27 patients (n=27) (13 women and 14 men) were recruited from our out-patient psychiatry clinic. All patients had been treated with atypical antipsychotics for at least 3 months and were in remission. Patients were evaluated for levels of HDL (High Density Lipoprotein), LDL (Low Density Lipoprotein), TG (Triglyceride) total cholesterol and fasting blood glucose, body weight, BMI (Body Mass Index), waist circumference and serum adiponectin levels.

RESULTS

Serum adiponectin levels were significantly lower (p:0.000) and body weights were significantly higher (p:0.003) in the patients who had been using atypical antipsychotics for longer than a year in comparison to patients who had been using atypical antipsychotics for one year or less.

CONCLUSION

Our findings supported the hypothesis that the length of administration of atypical antipsychotics has an effect on metabolic changes. They also highlight the fact that when investigating metabolic changes generated by atypical antipsychotic effects, the length of time that the patient has been on the atypical antipsychotics should also be considered.

Comparing ECT data of two different inpatient clinics: propofol or thiopental?

OBJECTIVE

This study compares the data of (modified) electroconvulsive theraphy (ECT) applications from two different inpatient clinics in Turkey: Kocaeli Derince Training and Research Hospital (Clinic-I) and Kocaeli University (Clinic-II).

METHODS

Recorded files of patients from the two clinics were compared in terms of ECT indications, number and duration of seizures, and anesthetic agents used (propofol vs. thiopental). ECT applications occurring between January 2011 and January 2013 were included in the study.

RESULTS

A total of 86 patients (9.5% of the inpatients) received ECT in Clinic-I and 103 patients (21.1% of the inpatients) in Clinic-II during the period studied. The yearly ECT rate (treated person rate per 10,000 per year) was 0.59/10,000 for Kocaeli (Turkey) as a whole. The overall number of ECT applications was 539 in Clinic-I and 999 in Clinic-II, and the average number of ECT sessions for each patient was 6.4 ± 2.33 in Clinic-I and 9.69 ± 4.66 in Clinic-II. The majority of indications were depressive disorders and insufficient response to medicine. Patients in the clinic which utilized thiopental as the anesthetic agent experienced more cardiovascular and respiratory side effects than the one which used propofol. The number of ECT sessions required was greater for patients with schizoaffective disorder than for others.

CONCLUSIONS

The administration of ECT was considered to be a reliable method of treatment in these clinics. With respect to specific anesthetic agents, propofol was found to have less hemodynamic side effects and shorter seizure durations than thiopental.

Is there a relationship between attention deficit/hyperactivity disorder and manic symptoms among children with mental retardation of unknown etiology?

Mental retardation (MR) is common and lifelong. In children and adolescents with MR, the rate of attention deficit/hyperactivity disorder (ADHD) and bipolar disorder is higher than that in the general population. However, there are no previous sufficient data that exist in establishing a relationship between ADHD and manic symptoms. The aim of the present study was to examine the relationship between manic symptoms and ADHD as well as oppositional-defiant disorder (ODD) and conduct disorder (CD) in children with MR of unknown etiology (MR-UE). A total of 167 children with MR-UE attending a rehabilitation and training school in Erzurum, Turkey, were included in the study. We administered the Child Disruptive Behavior Screening and Rating Scale related to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition and the Young Mania Rating Scale-Parent Version (P-YMRS) to parents. The age range of children and adolescents with MR-UE was between 5 and 21 years, with a mean age of 11.13 ± 3.75 years. In total, 5.8% of children and adolescents with MR-UE showed a border intelligence quotient (IQ), with 58.4% having a mild IQ, 29.2% having a moderate IQ, and 6.6% having severe IQ. According to the Child Disruptive Behavior Screening and Rating Scale related to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, 40.1% of children and adolescents with MR-UE had inattention, 19.9% had hyperactivity, 28.7% had ODD, and 13.3% had CD. A total of 7.2% of the children and adolescents with MR-UE had probable mania, and 1.8% had mania according to Young Mania Rating Scale-Parent Version. A positive correlation existed between the mean scores of Young Mania Rating Scale-Parent Version and the mean scores of inattention, hyperactivity, ODD, and CD (P = .000). Hyperactivity and ODD were predictors of being manic/probably manic. Diagnosing psychiatric disorders in children and adolescents with MR-UE is difficult but essential for better functioning. Manic symptoms and disruptive behaviors as well as ADHD symptoms were prevalent among children and adolescents with MR-UE and hyperactivity, and oppositional-defiant symptoms were predictors of manic symptoms in these patients.

Male genital self-mutilation as a psychotic solution

BACKGROUND

Male genital self-mutilation (GSM) is a rare, but serious phenomenon. Some of the risk factors for this act are: presence of religious delusions, command hallucinations, low self-esteem and feelings of guilt associated with sexual offences. Other risk factors include failures in the male role, problems in the early developmental period, such as experiencing difficulties in male identification and persistence of incestuous desires, depression and having a history of GSM. The eponym Klingsor Syndrome, which involves the presence of religious delusions, is proposed for GSM.

DATA SECTION

Four male GSM cases are presented: Case 1 and Case 2 were diagnosed with schizophrenia, Case 3 with schizophrenia and depressive disorder, not otherwise specified, and Case 4 with bipolar depression with psychotic features.

DISCUSSION

All definite and probable motives and cultural aspects for their GSM are discussed. Atonement is proposed as a new concept in formulating religiously themed psychotic male GSM.

Prevalence of orthorexia among medical students in Erzurum, Turkey

Orthorexia is a new term about eating behavior disorder and consists of pathologic obsession for biologically pure foods, free of herbicides, pesticides, and other artificial substances. It is not an independent diagnostic category, but it has some similarities with other eating disorders. This study was conducted to examine the orthorexia among 878 medical students. Of 878 students, 464 (52.8%) were male and 359 (40.9%) were female. The mean age, height, weight, and body mass index were 21.3 +/- 2.1 years, 171.0 +/- 8.5 cm, 65.6 +/- 12.3 kg, 22.4 +/- 2.99, respectively. The rates of the ORTO-11 scores between 0 and 15 was 1.9%; between 16 and 30, 57.5%; and between 31 and higher, 21.1%. There were 17 students with a score of 0 to 15. The mean score for the ORTO-11 test was 27. There were statistically significant differences between age, sex, and smoking habit of the students. In the male students, there was a statistically significantly higher tendency for orthorexia (P = .001), and there was a statistically significant difference between the age groups for tendency for orthorexia (P = .025). In logistic regression analysis, age, sex, Eating Attitude Test-40 (EAT-40), and height affected the ORTO-11 scores.

Normative data and factorial structure of the Turkish version of the Temperament and Character Inventory

Cloninger's dimensional psychobiological model of personality accounts for both normal and abnormal variation in 2 major personality components: temperament and character. Here, we examined the psychometric properties of the Turkish version of the Temperament and Character Inventory (TCI) in a healthy Turkish population, obtaining normative data for the Turkish TCI. The study was conducted in healthy volunteers at both Karadeniz Technical University School of Medicine and Atatürk University School of Medicine (n = 683). The Turkish sample had significantly lower mean scores on Novelty Seeking and Reward Dependence and higher mean scores on Harm Avoidance than the American sample. The Turkish sample had significantly lower scores on Self-Directedness, Cooperativeness, and Self-Transcendence. Self-Directedness and Harm Avoidance, Cooperativeness and Reward Dependence, and Cooperativeness and Self-Directedness were intercorrelated. The Cronbach coeficients were between 0.60 and 0.85 on temperament dimensions, and between 0.82 and 0.83 on character dimensions. The lowest Cronbach coefficients were found in Reward Dependence (0.60) and Persistence (0.62). A principal axis factor analysis with a 4-factor solution revealed the highest loadings on Novelty Seeking and Harm Avoidance and relatively weaker loadings on Reward Dependence and Persistence. A 3-factor solution for character subscales indicated the highest loadings on Cooperativeness and Self-Transcendence. The factorial structure was consistent with Cloninger's 7-factor model of personality, and test-retest indicated a good stability of scores over time. The reliability and factorial validity of the Turkish version of the TCI are therefore supported.

Bipolar Disorder (BD) and Obsessive Compulsive Disorder (OCD) Comorbidty or Varied Episodes in the Same Disorder

Previous studies have suggested that OCD has comorbidity with bipolar disorder (BD) (1,2). We evaluated the three bipolar OCD cases.

C1: Because of the OCD symptoms Chlomipramine was started. Her OCD symptoms improved in several days but manic symptoms was apeeared, switched to Lithium Carbonate. In her out patient exams, manic and obsessive compulsive symptoms were almost never observed simultaneously at the course.

C2: In 2003, her complaints started as combined OCD and Manic symptoms, Risperidon and Lithium carbonate were started, manic and OCD symptoms improved. In 2005, OCD and Depressive symptoms appeared together. She got improved with Lithium Carbonate and Chlomipramine. She had one episode with obsessive and manic symptoms or obsessive and depressive symptoms every year till now. Her uncle had Depression and her aunt had Bipolar disorder.

C3: Because of his OCD symptoms we prescribed SSRI and lower dose antipsychotic. At that time he hospitalized for his manic symptoms, his OCD was partially remitted. His manic symptoms improved with Lithium carbonate1200p/d. He had resistant obsessive compulsive symptoms and episodic manic symptoms. His father had M. Depressive episodes.

Conclusion:

Our cases suggest that bipolar OCD has episodic course, treatment resistant symtomatology, high family loading and high frequency of recurrence.

Factors influencing social distance from people with schizophrenia

The aim of this study was to investigate the nature of the relationship between public causal beliefs and social distance from people with schizophrenia. Regression analysis of the results of a vignette-based opinion survey was conducted on a representative population sample in Erzincan (n = 856). The findings of this study suggest that there is a positive relationship between biological causal beliefs (i.e. 'brain and disease' and 'heredity') and social distance from people with schizophrenia. It would be premature to draw conclusions with regard to interventions aimed at reducing discrimination based on stigma. However, our study provides stimulus for reconsidering the assumptions underlying biological concepts among the public, which might not contribute to a desired reduction in social distance from people with schizophrenia.

Neuropsychological effects of low mercury exposure in dental staff in Erzurum, Turkey

OBJECTIVE

To carry out measurements of the Hg levels and personal exposure in Turkish dental clinics, and to evaluate possible adverse effects on the CNS in dental personnel.

SETTING

Five dental clinics (1 private, 4 public) in Erzurum, Turkey.

SUBJECTS AND METHODS

43, Hg vapour-exposed dental staff were examined and 43 hospital employees with no known exposure to Hg acted as the control group. Hg concentrations in plasma and urine were analysed by atomic absorption spectrophotometry. Possible effects on the central nervous system (CNS) were estimated by neuropsychological tests (Weschler Memory Scale-Revised (WMS-R) and Verbal Test of Memory Processes (VTMP)) and two self-administered questionnaires (Symptom Checklist-90-Revised (SCL-90-R) and Beck Depression Inventory (BDI)).

RESULTS

The dental staff group had higher whole blood (B-Hg) and urine (U-Hg) Hg levels than the control group. The mean B-Hg value was 2.18 nmol/l and U-Hg was 1.17 nmol/mmol creatinine. U-Hg had an inverse relationship with logical memory (in WMS-R test) and total retention score (in VTMP test), and a positive relationship with increased scores of Anxiety and Psychoticism (in SCL-90-R).

CONCLUSION

These results may represent long-term consequences of low Hg exposure. In dentistry, to decrease toxic effects, proper Hg hygiene should be practiced by all dental health care workers.

Attitudes of hospital staff toward mentally ill patients in a teaching hospital, Turkey

The aim of this study was to examine the attitudes of hospital staff toward major mental diseases: schizophrenia and depression. Negative attitudes were common among all of the hospital staff, and were more common among academicians, resident physicians and nurses. Causes of attitude variations were discussed.

BACKGROUND

Attitudes of hospital staff are important for admission, early diagnosis and treatment, and the rehabilitation process of mentally ill patients.

AIMS

The main objective of this study was to investigate and compare hospital workers' attitudes toward and knowledge of schizophrenia and depression.

METHODS

In 2001, a total of 160 hospital staff (40 academicians, 40 resident physicians, 40 nurses and 40 hospital employees) in a teaching hospital were interviewed with a questionnaire. The questionnaire included items about background information, a one-paragraph vignette, questions on social distance and expected burden, recognition of mental illness, hospitalization, prognostic outcome, and to whom and where the patient should be admitted.

RESULTS

Although academicians, resident physicians, and nurses have sufficient knowledge about schizophrenia and depression, the frequency of their negative attitudes towards mentally ill subjects was more than that for uneducated hospital employees.

CONCLUSIONS

It was commented that this difference might be as a result of negative effects of the medical education system.

Neuro-Behçet's disease involving the pons with initial onset of affective symptoms

We report a case with Behçet's disease with initial onset of affective symptoms. This disease most commonly affects the brain stem in the nervous system, but a large lesion is very rare in the pons; initial onset of affective symptoms has not yet been reported in literature. This case was treated successfully with corticosteroids. Total clinical improvement was observed and the lesion was reduced in size within nine months (1.5 x 1.3 cm to 0.2 x 0.4 cm).

Left ear (right temporal hemisphere) advantage and left temporal hemispheric dysfunction in schizophrenia

In this study, to investigate the right or left ear advantages in psychiatric patients. the durations of hearing for right and left ears were assessed in 61 psychiatric patients, 26 with schizophrenia, 17 with depressive disorder, 13 with bipolar affective disorder, and 5 with brief psychotic disorder, plus 24 controls. Diagnoses were made on the basis of information provided from clinical interviews and the Structured Clinical Interview for DSM-IV (SCID). Schizophrenia was associated with a left ear advantage, and both depressive disorder and brief psychotic disorder were associated with right ear advantage as well as controls. These results suggest that their schizophrenia may be associated with a left temporal lobe dysfunction.

First-case postpartum psychoses in Eastern Turkey: a clinical case and follow-up study

OBJECTIVE

The aim of this study was to investigate the clinicodemographic features and long-term course of postpartum psychosis (PPP).

METHOD

A total of 64 in-patients with psychotic postpartum disorder, who were admitted for the first time to a psychiatry clinic, were reexamined retrospectively and then compared with 64 control patients. Follow-up investigation was carried out either by interviewing the patients personally or with the help of general practitioners (GPs). All patients were rediagnosed according to DSM-IV.

RESULTS

The majority of PPP patients were young, married, primiparae, had a low educational level and were living in rural areas. The mean onset time of PPP after delivery was 3.62 weeks. More than 75% of the patients with PPP had further psychotic episodes during the follow-up period of 11 years; 42% of the puerperal cases were diagnosed as schizophrenia at the follow-up investigation, and 59.3% of the patients had confuso-oneiroid syndrome.

CONCLUSION

These findings, unlike those of the Western studies, demonstrate that PPP is not uniform in different populations.

A case of childhood shigellosis with mutism

Bacillary dysentery, an acute infection caused by various strains of Shigella, is characterized by abdominal pain, tenesmus, and diarrhea with mucus, pus and blood. Neurologic manifestations including meningismus, delirium and convulsions may accompany the infection. We describe a thirteen-year-old girl who presented with headache, convulsion and loss of consciousness at the onset and developed diarrhea with blood and pus after hospitalization. The diagnosis of shigellosis was based on clinical data and isolation of the microorganism in the stool specimen. After improved physical functions, the patient developed mutism that continued for two days in the course of her illness, despite having no history of neurologic or psychological problems. She was diagnosed by a psychiatrist with organic mental syndrome NOS (Not Otherwise Specified) according to DSM-III-R criteria. None of the conditions that may cause mutism could be confirmed. This is the first reported case of mutism accompanying shigellosis.

Depression in an elderly population in Turkey

The prevalence of depression was investigated in 2 groups of elderly people in Turkey living in a public old people's home and in their own home. Depression was assessed according to the Hamilton Rating Scale for Depression, not clinical diagnosis. The prevalence of depression was 35% (33% for men, 37% for women) for the total population, 41% (40% for men, 42% for women) for those living in an institution and 29% (24% for men, 33% for women) for those living at home. Not being able to work actively, poor religious interest, widowhood, alcohol consumption, older age and physical disability were significantly correlated with the prevalence of depression. Institutional care was also associated with depression. The prevalence of depression was not related to sex, education, occupation or economic status.
