ABSTRACT
SUMMARY: Volume abnormalities in subcortical structures, including the hippocampus, amygdala, thalamus, caudate, putamen, and globus pallidus have been observed in schizophrenia (SZ) and bipolar disorder (BD), not all individuals with these disorders exhibit such changes. In addition, the specific patterns and severity of volume changes may vary between individuals and at different stages of the disease. The study aims to compare the volumes of these subcortical structures between healthy subjects and individuals diagnosed with SZ or BD. Volumetric measurements of lateral ventricle, globus palllidus, caudate, putamen, hippocampus, and amygdale were made by MRI in 52 healthy subjects (HS), 33 patients with SZ, and 46 patients with BD. Automatic segmentation methods were used to analyze the MR images with VolBrain and MRICloud. Hippocampus, amygdala and lateral ventricle increased in schizophrenia and bipolar disorder patients in comparison with control subjects using MRIcloud. Globus pallidus and caudate volume increased in patients with schizophrenia and bipolar disorder compared control subjects using Volbrain. We suggested that our results will contribute in schizophrenia and bipolar disorder patients that assessment of the sub-cortical progression, pathology, and anomalies of subcortical brain compositions. In patients with psychiatric disorders, VolBrain and MRICloud can detect subtle structural differences in the brain.
Se han observado anomalías de volumen en las estructuras subcorticales, incluidos el hipocampo, la amígdala, el tálamo, el núcleo caudado, el putamen y el globo pálido, en la esquizofrenia (SZ) y el trastorno bipolar (BD); no todos los individuos con estos trastornos presentan tales cambios. Además, los patrones específicos y la gravedad de los cambios de volumen pueden variar entre individuos y en diferentes etapas de la enfermedad. El estudio tuvo como objetivo comparar los volúmenes de estas estructuras subcorticales entre sujetos sanos e individuos diagnosticados con SZ o BD. Se realizaron mediciones volumétricas del ventrículo lateral, globo pálido, núcleo caudado, putamen, hipocampo y amígdala mediante resonancia magnética en 52 sujetos sanos (HS), 33 pacientes con SZ y 46 pacientes con BD. Se utilizaron métodos de segmentación automática para analizar las imágenes de resonancia magnética con VolBrain y MRICloud. El hipocampo, la amígdala y el ventrículo lateral aumentaron en pacientes con esquizofrenia y trastorno bipolar en comparación con sujetos de control que utilizaron MRIcloud. El globo pálido y el núcleo caudado aumentaron en pacientes con esquizofrenia y trastorno bipolar en comparación con los sujetos control que utilizaron Volbrain. Sugerimos que en pacientes con esquizofrenia y trastorno bipolar, nuestros resultados contribuirán a la evaluación de la progresión subcortical, la patología y las anomalías de las composiciones cerebrales subcorticales. En pacientes con trastornos psiquiátricos, VolBrain y MRICloud pueden detectar diferencias estructurales sutiles en el cerebro.

OBJECTIVE: Autism spectrum disorder (ASD) is a complex neurodevelopmental syndrome with an increasingly prevalent etiology, yet not fully understood. It has been thought that vitamin D, complex B vitamin levels and homocysteine are associated with environmental factors and are important in ASD. The aim of this study was to examine serum vitamin D, vitamin D receptor (VDR), homocysteine, vitamin B6, vitamin B12 and folate levels in ASD. METHODS: In this study, serum vitamin D and VDR, homocysteine, vitamins B6, B12 and folate levels were determined in 60 patients with ASD (aged 3 to 12 years) and in 45 age-gender matched healthy controls. In addition, calcium, phosphorus and alkaline phosphatase, which are associated with vitamin D metabolism, were measured from serum in both groups. ASD severity was evaluted by the Childhood Autism Rating Scale (CARS). RESULTS: Serum vitamin D and VDR were substantially reduced in patients with ASD in comparision to control group. However, homocysteine level was significantly higher and vitamin B6, vitamin B12 and folate were also reduced in patients with ASD. Total CARS score showed a positive association with homocysteine and a negative correlation with vitamins D,B6, B12, folate and VDR. CONCLUSION: This comprehensive study, which examines many parameters has shown that low serum levels of vitamins D, B6, B12, folate and VDR as well as high homocysteine are important in the etiopathogenesis of ASD. However, further studies are required to define the precise mechanism(s) of these parameters and their contributions to the etiology and treatment of ASD.
ABSTRACT
Estrogen has a crucial role in the regulation of reproductive and neuroendocrine function and exerts its effects through two classes of receptors, nuclear and membrane estrogen receptors (mERs). G protein-coupled estrogen receptor 1 (GPER) is a member of mERs, and despite limited research on the levels of GPER in patients with psychiatric diseases, a role of GPER in such conditions has been suggested. Here we evaluated serum estrogen and GPER levels in children with attention deficit hyperactivity disorder (ADHD) in relation to their age- and gender-matched healthy controls. A total of 82 children were included in the study, 47 drug- naïve patients with ADHD (age: 6-12 years; male/female: 34/13) and 35 healthy controls (age: 6-12 years; male/female: 19/16). The subgroups according to ADHD types were inattentive, hyperactive/impulsive, and combined. Serum estrogen was measured using an immunoassay system, while serum GPER was determined using a commercial sandwich enzyme-linked immunosorbent assay kit. Estrogen levels in children with ADHD were similar as in control group, while GPER levels were significantly lower in ADHD group compared to controls (p < 0.05). Logistic regression analysis showed a significant association between GPER levels and ADHD (p < 0.05), and no association between estrogen levels and ADHD (p > 0.05). No significant differences were found in GPER and estrogen levels between ADHD subgroups (p > 0.05). To the best of our knowledge, this study is the first to investigate estrogen and GPER levels in ADHD. Our preliminary findings suggest a relationship between serum GPER levels and ADHD, and this should be further investigated.

OBJECTIVE: Generalized anxiety disorder (GAD) is a common anxiety disorder. Although lots of research done to reveal neurobiological basis of GAD, it is still unclear. Diagnosis of GAD depends on subjective complaints of patients, thus the need for a biological marker is constantly emerging. In this study, we aimed to investigate diagnostic value of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in GAD. METHODS: We evaluated MDA, SOD, and CAT levels in peripheral blood of 46 patients and 45 controls. MDA was measured with Ohkawa's methods, SOD was measured with Fridovich method, and CAT was measured with Beutler's method. RESULTS: MDA was significantly increased in patients than controls, medians 4.05 nmol/mg and 1.71 nmol/mg respectively, pï¼0.001; SOD and CAT activity was significantly decreased in patients than controls, medians of SOD were 159.07 U/mg and 301.87 U/mg, pï¼0.001 respectively, medians for CAT were 138.47 U/mg and 160.60 U/mg respectively. We found high correlation between Hamilton Anxiety Rating Scale and SOD, MDA r values were 0.723 and 0.715 respectively, pï¼0.001 for both. Receiver operator characteristic (ROC) curve analysis showed high diagnostic performance for MDA and SOD, low diagnostic performance for CAT, areas under curve were 1.0, 1.0, and 0.648 respectively. CONCLUSION: Our results reveal possible diagnostic value of MDA, less likely of SOD but not CAT. Future studies should investigate diagnostic value of oxidants and antioxidantn enzymes in larger samples and include diagnostic value of these parameters.
ABSTRACT
MicroRNAs (miRNAs) are 22 nucleotide long RNA transcripts, their synthesis starts in nucleus and continues in cytoplasm. As being critical for post-transcriptional regulators of gene expression they have been investigated in psychiatric disorders. There are numerous studies performed in peripheral tissues for psychiatric disorders. Here in this article, we aimed to review some common miRNAs denoted significant in at least two studies and their relevance to psychiatric research. We focused on miR-320, miR-106, miR-34, miR-223, miR-107, and miR-134.
ABSTRACT
OBJECTIVE: The facts that depression is more prevalent in females than in males and females are exposed to depression more commonly during certain hormonal fluctuating periods indicate the role of sex hormones in physiopathology. Estrogen acts over estrogen receptors alpha and beta and recently identified G protein-coupled estrogen receptor 1 (GPER1). The present study aimed, for the first time, to evaluate serum GPER1 levels in drug-naïve major depressive disorder (MDD) patients. METHODS: The study included 56 newly diagnosed drug-naïve MDD patients aged between 18 and 50 years and 42 age- and gender-matched healthy volunteers. Medical history was obtained and physical examinations, laboratory tests, and the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A) were performed. The serum GPER1 levels were measured. RESULTS: The HAM-D score was significantly higher in the MDD patients than in the controls. The GPER1 level was significantly higher in the MDD patients than in the controls. A positive correlation was found with GPER1 levels and depression scores. The receiver operating characteristic analysis revealed sensitivity, specificity, positive predictive value, and negative predictive value as 82.1%, 90.5%, 92.0%, and 79.2%, respectively, for the presence of depression, when the serum GPER1 value was ≥0.16. CONCLUSION: This study demonstrated significantly higher serum GPER1 levels in the MDD patients than in the controls, a positive correlation was found between GPER1 levels and depression scores and serum GPER1 level was valuable in predicting the presence of depression.
ABSTRACT
OBJECTIVES: Although there has been much research into the cause of stuttering, it has not yet been fully clarified. There is known to be a close relationship between stress severity and stuttering. The aim of this study was to evaluate the levels of oxidative and nitrosative stress by comparing a stuttering group and a control group. It was also aimed to evaluate the relationship between the oxidative and nitrosative stress levels and the severity of the stutter. METHODS: The study included a total of 80 individuals, comprising a study group of 40 and a control group of 40. The severity of the stutter in the patient group was evaluated with the Stuttering Severity Instrument 3 (SSI). Blood samples were taken from both the patient and control groups and malondialdehyde (MDA), 3 nitrotyrosine (3-NT), nitric oxide (NO), catalase (CAT), and superoxide dismutase (SOD) concentrations were examined. RESULTS: In the stuttering patients, MDA, 3-NT, NO, CAT, and SOD activity were determined to be statistically significantly higher than those of the control group (all p:0.001). In the ROC analysis, there was good diagnostic value for NO, with the area under the curve as 1.0. A direct, positive, statistically significant correlation was determined between SSI points and MDA values (r = 0.317, p = 0.046). CONCLUSION: The results of the study showed that the oxidative and nitrosative stress levels of the stuttering patients were higher than those of the control group. With 100% sensitivity and specificity, it is thought that NO in particular could be important for the diagnosis and treatment of these patients. As the severity of the stutter increased, so there was an increase in MDA, suggesting that MDA is important in stuttering.

Sex hormones, specially estrogen, and it is receptors plays a critical role in the pathogenesis of psychiatric disorders including autism spectrum disorders (ASD). The aim of this study was to investigate the relationship between ASD and G protein-coupled estrogen receptor (GPER), a recently discovered estrogen receptors, and also to study the relation of serum GPER levels with the severity of autistic symptoms. The present study included 45 children with drug naive ASD diagnosed by DSM-V criteria, aged between 3 and 12 years and 40 age- and gender-matched healthy controls. The severity of ASD was evaluated with the Childhood Autism Rating Scale (CARS) total score. The GPER levels in the serum were measured using the quantitative sandwich enzyme immunoassay technique. The serum GPER level was significantly lower in the ASD patients than in the controls. There was a negative significant correlation between the GPER level and the CARS score. There were no significant correlations between GPER level with estradiol and age. In conclusion, this study demonstrated that the decreased serum GPER levels were associated with ASD and GPER may play an important role in the etiology of ASD.

Venlafaxine is a serotonergic and noradrenergic reuptake inhibitor which is used for the treatment of depression. We report a case of galactorrhea in a patient with major depressive disorder after starting treatment with venlafaxine. In particular, we discuss the course of hyper and normoprolactinemic galactorrhea. We managed this side effect initially by dose reduction and further by switching to essitalopram. Physicians should be aware of endocrinologic side effects such as galactorrhea during the serotonin and noradrenaline reuptake inhibitor treatment.
ABSTRACT
OBJECTIVE: The umbilical cord consists of two arteries and one vein and it functions in the transport between the maternal and fetal circulation. Biochemical analysis of fetal cord blood (FCB) during delivery could be beneficial in terms of understanding the fetal environment. In this study, we aimed to investigate oxidative parameters like malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels in FCB during delivery. METHODS: We collected FCB samples during caesarean section. Our study included 33 depressed mothers and 37 healthy controls. We investigated MDA, SOD, and CAT levels in FCB samples. RESULTS: We found no significant difference between groups in terms of MDA (p=0.625), SOD (p=0.940), and CAT (p=0.413) levels. CONCLUSION: Our study reveals probable protective effects of the placenta from oxidative stress. Future studies should include larger samples.
ABSTRACT
OBJECTIVE: That treatment with second-generation antipsychotics (SGAs) causes metabolic side effects and atherosclerosis in patients with schizophrenia and bipolar disorder (BD) is well-known. Increased arterial stiffness is an important marker of arteriosclerosis and has been identified as an independent risk factor for cardiovascular diseases. We measured pulse wave velocity (PWV) as a marker of arteriosclerosis in patients with schizophrenia and BD who use SGAs. METHODS: Patients and controls were collected from our psychiatry outpatient clinics or family medicine. Mental illness was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. Mean age, gender, systolic and diastolic blood pressure, body mass index, Framingham risk score (FRS), etc. were determined. Simultaneous electrocardiography and pulse wave were recorded with an electromyography device. The photo-plethysmographic method was used to record the pulse wave. Inclusion criteria included use of SGAs for at least the last six months. Patients with diseases that are known to cause stiffness and the use of typical antipsychotics were excluded. RESULTS: Ninety-six subject (56 patients, 40 controls) were included in our study. There were 49 females, 47 males. Patients had schizophrenia (n=17) and BD (n=39). Their treatments were quetiapine (n=15), risperidone (n=13), olanzapine (n=15), and aripiprazole (n=13). Although differences in mean age, gender, and FRS in the patient and control groups were not statistically significant (p=1), PWV was greater in patients in the antipsychotic group (p=0.048). CONCLUSION: This study supported the liability to stiffness in patients with schizophrenia and BD. Using SGAs may contribute to arterial stiffness in these patients.
ABSTRACT
The aim of this study was to investigate the impact of aggression levels on the quality of life (QoL) of epilepsy patients. This study was conducted on 66 volunteer control subjects, who were matched by age and sex to the patient group, which consisted of 66 patients who applied to the Psychiatry and Neurology clinics for outpatient treatment, were aged between 18 years and 65 years, and were diagnosed with epilepsy. A sociodemographic and clinical data form designed by us was distributed among the study participants, along with Buss-Perry Aggression Scale, Beck Anxiety Scale, Beck Depression Scale, and the Quality of Life Scale Short Form (SF-36). Compared with the control group, the patient group displayed higher scores in all subgroups of Buss-Perry Aggression Scale subscales at a statistically significant level (P<0.05). As per the SF-36 questionnaire, physical functioning, physical role disability, general health perception, social functioning, mental health perception, and pain subscales were statistically lower in the patient group (P<0.05). Significant links between Beck Depression Scale and Beck Anxiety Scale levels, as well as some subscales of QoL and aggression levels, were also determined. In conclusion, epilepsy patients experienced impaired QoL compared with the healthy control group and their QoL was further impaired due to increased levels of anxiety, depression, and aggression.
ABSTRACT
Sex hormones, particularly estrogen, are suggested to play a role in the physiopathology of generalized anxiety disorder (GAD). Estrogen functions through the estrogen receptors alpha and beta and the recently discovered G protein-coupled estrogen receptor 1 (GPER1). This study aimed, for the first time, to evaluate serum GPER1 levels in drug-naive patients with GAD. This study included 40 newly diagnosed drug-naive patients with GAD aged between 18 and 50 years and 40 age- and gender-matched healthy controls. Medical histories were obtained, and physical examinations and laboratory tests were conducted; the Hamilton Anxiety Rating Scale (HAM-A) was also used for all participants. Serum GPER1 levels were measured. The serum GPER1 level was significantly higher in the patients with GAD than in the controls. A positive significant correlation was observed between the GPER1 level and the HAM-A score. The receiver operating characteristic analysis revealed a sensitivity, specificity, positive predictive value, and negative predictive value of 85.0%, 82.5%, 82.9%, and 84.6%, respectively, for the presence of anxiety when the serum GPER1 value was ≥0.14 (the area under the curve was 0.904.). In conclusion, this study demonstrated that GPER1 levels were associated with the anxiety levels of patients, and that the serum GPER1 level was a valuable predictor of the presence of anxiety independent of gender.

The investigation of fetal cord blood (FCB) during child delivery has created a novel topic in the field of psychiatric research. The umbilical vein receives nutrients and oxygen from the mother's circulation and transports them to the fetal circulation. Investigating fetal cord blood during delivery is beneficial for understanding the fetal environment. Depression in pregnancy is associated with medical and emotional burdens. In this study, we aimed to investigate glutathione peroxidase (Gpx) and myeloperoxidase (MPO) activity in the FCB of depressed mothers and healthy controls. Our study included 45 depressed mothers and 59 healthy controls. The FCB samples were collected from the umbilical vein during delivery. We found that Gpx levels were significantly decreased in the FCB of depressed mothers than healthy controls, medians were 0.14 U/ml and 0.16 U/ml respectively, Z: -3.567 and p < 0.001. MPO levels were similar in both groups, medians were 1.0 U/L and 1.2 U/L respectively, Z: -1.837 and p:0.066. Depression in pregnancy may be associated with decreased antioxidant levels, and this condition may cause an oxidative load, which may lead to improper brain development. Future studies should be performed in larger samples to clarify our preliminary results.

Major depression is a most frequent disorder, its diagnosis depends on patient interview, and yet we do not have a reliable biomarker for depression. Oxidative stress is defined as increase in oxidation or decrease is antioxidant defense mechanisms. Here, we aimed to investigate malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) activity and their diagnostic performance in depressed patients and healthy controls. We collected blood samples from 50 patients and 50 controls. We found MDA levels were significantly higher in the patients than controls, with medians at 4.04nmol/mg and 1.64nmol/mg, respectively, p<0.001. SOD activity was significantly decreased in depressed patients than healthy controls, with means at 143.50U/mg and 298.12U/mg, respectively, p<0.001. CAT activity was similar in both groups, p=0.517. ROC analysis showed good diagnostic value for MDA and SOD, with the area under the curve at 1.0 for both. We found high correlation between SOD and Ham-D scores (r=0.747, p<0.0001) and between MDA and Ham-D scores (r=0.785, p<0.0001). Overall, these results demonstrate that oxidative stress is increased in depressed patients. MDA increase seem to be a common finding for major depression. We believe MDA could be a good biomarker candidate for major depression, but not SOD. Future studies should focus on the diagnostic value of MDA in larger samples.

Depression in pregnancy may have negative effects on birth outcomes. It may also effect the intrauterine environment of the fetus. The umbilical cord is the conduit between the fetus and placenta, and functions in the transport between fetus and mother. Investigating biochemical parameters in fetal cord blood (FCB) during delivery may be helpful to understanding to what the fetus is exposed to, at least in the last trimester. In this study, we aimed to investigate total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) in the FCB of depressed mothers and healthy controls during delivery. Our study included 33 depressed mothers and 37 healthy controls. TAS, TOS, and OSI were measured according to Erel's method. We found that TAS, TOS, and OSI levels were similar in patients and healthy controls; however, the birth weights of depressed patients were significantly lower than those of healthy controls. Our results suggest that the placental barrier may prevent from oxidative stress. Future studies should include blood samples collected simultaneously from mothers during delivery.

BACKGROUND: Here we aimed to investigate sociodemographic characteristics, psychiatric history, and association between sociodemographic characteristics and anxiety levels of violence-exposed patients admitted to emergency clinic. METHODS: This study consists of 73 violence-exposed patients admitted to emergency clinic who were literate and agreed to participate in the study. A sociodemographic data form created by us to investigate alcohol-substance abuse, suicide attempt, previous history of trauma, self and family history of psychiatric disorders and Beck Anxiety Inventory was given to the patients. RESULTS: Of the patients exposed to violence 63% (n=46) were female and 27% (n=27) were male. Of these patients, 68.5% (n=50) were married, 43.8% (n=25) were workers, 34.2% were housewives, 11% were unemployed, and 11% were civil servants. Of the violence-exposed patients, 56.2% (n=41) were primary school, 21.9% (n=16) were high school, and 21.9% (n=16) were university graduates. Smoking and alcohol use rates were 54.8% (n=40) and 17.8% (n=13), respectively. The most common trauma type was assault using physical force with a ratio of 78.1% (n=57). In addition, anxiety scores were high in 42.5% (n=31) and moderate in 9.6% (n=7) of the patients. Mentioned psychiatric disorder was present in 17.8% (n=13) of the patients and 19.2% (n=14) of the patients' relatives. The correlation between sociodemographic characteristics and anxiety scores revealed that married patients had higher anxiety scores (P<0.01) and patients assaulted by their parents had lower anxiety scores (P<0.00). CONCLUSION: A total of 63% of the violence-exposed patients admitted to emergency room were females, 56.2% were primary school graduates, and 43.8% were factory workers; this result shows that low socioeconomical status and education level affect exposure to trauma especially in females. In addition, ~20% of the patients and patients' relatives had a psychiatric disorder and 53.4% of perpetrators were parents, spouses, and children; this result shows that psychiatric history and family relations are one of the issues that should be taken into account and treated.
ABSTRACT
BACKGROUND: The primary aim of this study was to compare the differences in temperament-character traits, suicide attempts, impulsivity, and functionality levels of patients with bipolar disorder I (BD-I) and bipolar disorder II (BD-II). METHODS: Fifty-two BD-I patients and 49 BD-II patients admitted to Erenköy Mental and Neurological Disease Training and Research Hospital psychiatry clinic and fifty age- and sex-matched healthy control subjects were enrolled in this study. A structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition Axis I Disorders, Temperament and Character Inventory, Barrett Impulsiveness Scale-11 (BIS-11), Hamilton Depression Inventory Scale, Young Mania Rating Scale, and Bipolar Disorder Functioning Questionnaire (BDFQ) were administered to patients and to control group. RESULTS: No statistically significant difference in sociodemographic features existed between the patient and control groups (P>0.05). Thirty-eight subjects (37.62%) in the patient group had a suicide attempt. Twenty-three of these subjects (60.52%) had BD-I, and 15 of these subjects (39.47%) had BD-II. Suicide attempt rates in BD-I and II patients were 60.52% and 39.47%, respectively (P<0.05). Comparison of BD-I and II patients with healthy control subjects revealed that cooperativeness (C), self-directedness (Sdi), and self-transcendence (ST) scores were lower and novelty seeking (NS1 and NS2), harm avoidance (HA4), and reward dependence (RD2) subscale scores were higher in patients with BD-I. When BD-I patients were compared with BD-II patients, BIS-11 (attention) scores were higher in patients with BD-II and BIS-11 (motor and nonplanning impulsivity) scores were higher in patients with BD-I. According to BDFQ, relations with friends, participation in social activities, daily activities and hobbies, and occupation subscale scores were lower and taking initiative subscale scores were higher in patients with BD-I. Social withdrawal subscale scores were higher in patients with BD-II. CONCLUSION: In our study, NS, HA, and RD scores that may be found high in suicide attempters and Sdi scores that may be found low in suicide attempters were as follows: NS1, NS2, HA4, and RD2 subscale scores were high and Sdi scores were low in patients with BD-I, suggesting a higher rate of suicide attempts in this group of patients. In addition, C and Sdi scores that indicate a predisposition to personality disorder were significantly lower in patients with BD-I than patients with BD-II and healthy controls, suggesting a higher rate of personality disorder comorbidity in patients with BD-I. Higher impulsivity and suicidality rates and poorer functionality in patients with BD-I also suggest that patients with BD-I may be more impulsive and more prone to suicide and have poorer functionality in some areas.
ABSTRACT
Cancer is a physical disease and also one of the leading clinical manifestations where psychosocial problems are prevalent. Psychosocial problems that these patients may have in the long run include anxiety, uneasiness, mourning, helplessness, fatigue, impairment of concentration, sleep disorders, mental and cognitive reservation, sexual dysfunction, infertility, psychological distress, and psychiatric disorders. Psychosocial problems have a nature of underpinning the emergence of psychological troubles. The prevalence of psychological disorders in patients with cancer range from 29% to 47%. Psychiatric disorders that are likely to be seen are severe stress disorder, adjustment disorder, depressive disorder, and other neurotic disorders. It is considered by the present author that in the event of breast cancer, potential psychiatric disorders may affect prognosis of the disease, adherance to and success of therapy, social and societal functioning, and survival rate. This paper aims to review the psychiatric symptoms and diseases that may develop in patients with breast cancer, which is one of the most frequent types of a globally common disease; i.e., cancer, as well as the impact of psychiatric symptoms on the treatment of disease.
ABSTRACT
BACKGROUND: The majority of patients with schizophrenia and mood disorders have disruptions in sleep and circadian rhythm. Melatonin, which is secreted by the human pineal gland, plays an important role in sleep and circadian rhythm. The aim of the present study was to evaluate and compare pineal gland volumes in patients with schizophrenia and mood disorders. SUBJECTS AND METHODS: We retrospectively evaluated the pineal gland volumes of 80 cases, including 16 cases of unipolar depression, 17 cases of bipolar disorder, 17 cases of schizophrenia, and 30 controls. The total pineal gland volume of all cases was measured via magnetic resonance images, and the total mean pineal volume of each group was compared. RESULTS: The mean pineal volumes of patients with schizophrenia, bipolar disorder, unipolar depression, and the controls were 83.55±10.11 mm(3), 93.62±11.00 mm(3), 95.19±11.61 mm(3) and 99.73±12.03 mm(3), respectively. The mean pineal gland volume of the patients with schizophrenia was significantly smaller than those of the other groups. CONCLUSIONS: Our data show that patients with schizophrenia have smaller pineal gland volumes, and this deviation in pineal gland morphology is not seen in those with mood disorders. We hypothesize that volumetric changes in the pineal gland of patients with schizophrenia may be involved in the pathophysiology of this illness.
