Evaluation of oxidative stress in patients with recalcitrant warts

BACKGROUND

Warts are benign conditions of the skin and mucosa caused by human papilloma viruses (HPV) that affect many people worldwide.

OBJECTIVE

The aim of this study was to evaluate OS by TOS/TAS, levels of 8-hydroxy-2-deoxyguanosine (8-OHdG) an indicator of DNA damage, and also protein oxidation levels by determining the dynamic serum thiol/disulphide homeostasis in patients with warts. We also aimed to investigate whether there is a relationship between thiol/disulphide homeostasis, recalcitrance of warts and DNA damage.

METHODS

Forty patients of age ≥18 years, having recalcitrant genital and/or non-genital warts that persisted for more than 2 years, 40 patients with warts that persisted for <2 years and 40 healthy controls were enrolled in the study. Blood TAS, TOS, OSI, 8-OHdG and dynamic thiol/disulphide homeostasis were evaluated.

RESULTS

Significant differences were detected between the groups in the levels of 8-OHdG, TOS, OSI, total thiol, native thiol, reduced thiol, as well as native thiol/total thiol ratio, disulphide/total thiol ratio and disulphide/native thiol ratio. Compared with the controls, patients with recalcitrant warts had significantly higher levels of 8-OHdG, TOS and OSI levels. Total thiol and native thiol levels were significantly lower in patients with recalcitrant warts compared with patients with warts that persisted for <2 years. Disulphide levels were significantly higher in the latter group of patients compared with patients with recalcitrant warts and controls. Native thiol/total thiol ratio was significantly higher in both patient groups compared with controls whereas disulphide/total thiol and disulphide/native thiol ratios were significantly lower in both patient groups than in controls.

CONCLUSION

Our findings suggest that impairment of thiol disulphide homeostasis in patients with recalcitrant warts may lead to increased OS and DNA damage. Thus, antioxidant administration with thiol containing proteins may help in the regression of warts and thereby prevent carcinogenesis.

Should patients be informed about the side effects of psychotropic drugs? According to us: Yes

BACKGROUND

In our daily clinical practice, we observe that patients who were informed about the probable side effects of any medication experience less side effects. For this reason, we decided to examine this in a systematic investigation.

METHODS

We divided patients into two groups, the informed and uninformed one about side effects of the drugs. During the control examination, tolerability of the drugs given was questioned in detail.

RESULTS

At the end of one month, the mean total UKU score was statistically significantly lower in patients from the informed group compared to that of the uninformed one (p < 0.05). The proportion of patients who discontinued the drug during the one month-period was statistically significantly higher in the uninformed group compared to informed group 9% in the informed group vs. 25% in the uninformed group) (p < 0.05).

CONCLUSIONS

Finally, we found that giving information about the side effects of a psychopharmacological agent seems to be useful and to provide beneficial effects on the tolerability of the drug, independent of the kind of psychotropic agent.

Psychiatric symptoms in migraine patients and their attitudes towards psychological support on stigmatization

OBJECTIVE

Although migraine patients experience more psychological problems when compared to the general population, they are usually not treated. The reasons for non-treatment of these problems are not clear. The anxiety and concern of migraine patients about stigmatization may also prevent them to express psychological symptoms. The present study aimed to investigate the attitudes and behavior of migraine patients about receiving psychological help and their concerns about stigmatization.

MATERIAL AND METHOD

The study group included 50 18-49 years old patients diagnosed with migraine in the neurology clinic and the control group included 50 healthy individuals with similar age, gender socio demographic characteristics with the study group. Attitude Scale Towards Seeking Professional Help (ASPH-SF), Self-Stigma in Seeking Professional Help Scale (SSPHS), Intentions to Seek Psychological Help Scale (ISHP), Stigma Scale for Receiving Psychological Help (SSRPH) and Symptom Checklist (SCL-90-R) were applied to all participants.

FINDINGS

The comparison of the patient and control groups based on SCL-90-R findings demonstrated that the patient group scores in somatization, anxiety (p = 0.000), depression (p = 0.003), anger (p = 0.02), interpersonal sensitivity (p = 0.006), phobia (p = 0.001), paranoid thoughts (p = 0.012), psychosis (p = 0.031) subscales and additional subscale (p = 0.014) and general symptom index (p = 0.001) scores were higher. Based on SCL 90, it was found that patients with higher levels of symptoms had higher social stigma scores when compared to patients with lower symptom levels (p = 0.007). Migraine patients with high symptom levels were found to have significantly lower rates of seeking psychiatric help (14% vs 33%) when compared to the control group. There was no difference between the patient and control groups based on ASPH-SF, SSPHS, ISPH and SSRPH scale scores.

CONCLUSION

Although migraine patients exhibit higher levels of psychiatric symptoms when compared to healthy individuals, it was determined that only a minority of these patients receive psychiatric treatment. Especially patients with high level of psychiatric symptoms could have sought less psychiatric help due to the concerns of stigmatization.

Orbito-frontal cortex and thalamus volumes in the patients with obsessive-compulsive disorder before and after cognitive behavioral therapy

Background The effect of a variety of treatment modalities including psychopharmacological and cognitive behavioral therapy on the brain volumes and neurochemicals have not been investigated enough in the patients with obsessive-compulsive disorder. Therefore, in the present study, we aimed to investigate the effect of cognitive behavioral therapy on the volumes of the orbito-frontal cortex and thalamus regions which seem to be abnormal in the patients with obsessive-compulsive disorder. We hypothesized that there would be change in the volumes of the orbito-frontal cortex and thalamus. Methods Twelve patients with obsessive-compulsive disorder and same number of healthy controls were included into the study. At the beginning of the study, the volumes of the orbito-frontal cortex and thalamus were compared by using magnetic resonance imaging. In addition, volumes of these regions were measured before and after the cognitive behavioral therapy treatment in the patient group. Results The patients with obsessive-compulsive disorder had greater left and right thalamus volumes and smaller left and right orbito-frontal cortex volumes compared to those of healthy control subjects at the beginning of the study. When we compared baseline volumes of the patients with posttreatment ones, we detected that thalamus volumes significantly decreased throughout the period for both sides and that the orbito-frontal cortex volumes significantly increased throughout the period for only left side. Conclusions In summary, we found that cognitive behavioral therapy might volumetrically affect the key brain regions involved in the neuroanatomy of obsessive-compulsive disorder. However, future studies with larger sample are required.

Is Cytomegalovirus Surveillance Necessary for Patients With Low Reactivation Risk in an Autologous Hematopoietic Cell Transplantation Setting?

BACKGROUND

In an autologous hematopoietic cell transplantation (AHCT) setting, routine cytomegalovirus (CMV) surveillance is not indicated except in high-risk situations. On the other hand, some studies reported increased CMV reactivation in AHCT setting as a result of incorporation of novel agents into treatment algorithms, such as bortezomib and rituximab. We retrospectively analyzed CMV reactivation and infection rates in patients with no high-risk features, who were treated with AHCT.

METHODS

During January 2010 to November 2015, all consecutive, CMV-seropositive patients were included. The viral copy numbers were measured twice a week from the start of the conditioning regimen until engraftment, once a week for the remaining time period until day 30 after AHCT and once weekly only for patients who had been diagnosed with CMV reactivation before and who developed primary/secondary engraftment failure during 31 to 60 days after AHCT.

RESULTS

One hundred one (61.6%) men and 63 (38.4%) women were included in the study. The median age of study cohort was 51 years (range, 16-71 years). The indications for AHCT were Hodgkin lymphoma, non-Hodgkin lymphoma, and multiple myeloma in 44 (26.8%), 41 (25%), and 79 (48.2%) patients, respectively. CMV reactivation occurred in 60 (37%) patients, and 13 patients (8%) received pre-emptive ganciclovir treatment.

CONCLUSIONS

On the basis of our results, it might be stated that CMV surveillance may be recommended during 40 days after AHCT in countries with a high CMV prevalence, even in patients without high-risk features regarding reactivation. Additionally, the risky conditions necessitating CMV screening after AHCT must be re-defined in the era of novel agents.

The Relationship between Ghrelin and Copeptin Levels, and Anxiety and Depression Levels in Suicide Attempts

Objective

It was aimed to detect acylated ghrelin (AG), unacylated ghrelin (UG) and copeptin levels in patients with suicide attempts and to determine if these biomarkers are risk factors for suicide attempts.

Methods

Serum copeptin, AG and GU levels were screened in 128 patients who were admitted to emergency department with suicide attempts and 59 healthy controls. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were applied simultaneously, and the data were compared statistically.

Results

AG, UG and copeptin levels were higher in the patient group compared with the healthy control group. BAI scores of patients were found to be positively correlated with BDI scores. While there was a significant difference (p=0.0064) between psychiatric and non-psychiatric patients with suicide attempts in terms of BAI scores, there were no differences in BDI scores and levels of biomarkers. We found significantly increased BDI and BAI scores and increased levels of AG, UG and copeptin in psychiatric and non-psychiatric patients compared with healthy individuals. The specificities yielded by receiver operating characteristic curve analysis in patients with suicide attempts were as follows: 91.53% for AG, 72.88% for UG and 94.92% for copeptin.

Conclusion

Serum levels of AG, UG and copeptin increase with increasing anxiety and depression in patients with suicide attempts. Increased levels of AG, UG and copeptin could be considered a risk factor for suicide attempts.

Protective effect of thymoquinone against cyclophosphamide-induced genotoxic damage in human lymphocytes

OBJECTIVE

Protective effect of thymoquinone (TQ) against the cytotoxic and genotoxic effects of cyclophosphamide (CP) was assessed in human peripheral blood lymphocyte culture.

METHODS

Mitotic indices were determined as endpoints of cytotoxicity, while sister chromatid exchanges (SCE) served as endpoints of genotoxicity. Firstly, the genotoxic effect of 0.16 µg/ml of CP was tested and CP was detected as genotoxic. In the second set, CP group was treated with 20 µM and 40 µM TQ.

RESULTS

TQ reduced the SCE frequencies, suggesting its protective action on human lymphocytes in vitro against the CP induced genotoxic damage.

CONCLUSIONS

Our results suggest that TQ produces a protective mechanism against CP-induced genetic damage, and suggest a role of DNA strand breaks in the genotoxicity (Tab. 1, Fig. 1, Ref. 19).

Illicit substance use among persons admitted to probation polyclinic of a regional mental hospital in the Eastern Anatolia, Turkey

OBJECTIVES

To investigate the illicit substance use trends by gender and year in Eastern Turkey, Elazığ.  

METHODS

This is a retrospective study designed to assess the drug use prevalence in persons who admitted to the Probation Policlinic of Elazig Mental Health Hospital between January 2011 and December 2014 in Eastern Turkey, Elazığ. Laboratory screening tests for drugs were studied using the cloned enzyme donor immunoassay technique in urine.  

RESULTS

The study consisted of 10267 males (95.3%)  and 510 females (4.7%), with a mean age of 30.42±10.83 years. Overall prevalence was 32.1% for cannabis, 3.8% for opiate, 0.35% for cocaine and 1.2% for polydrug usage. The prevalence of cannabis was significantly higher in males (32.7%, p=0.000). The prevalence of cannabis use was the lowest in the age group of 50-59 while it was significantly higher in the age groups of 20-29 and 30-39 (p=0.000). The prevalence of opiate use showed a significant difference among the years (p=0.000).There was a significant difference in the prevalence of cocaine use among the years (p=0.02). The prevalence of polysubstance use showed a significant difference among years (p=0.000). 

CONCLUSION

Cannabis was the most common illicit drug in the east of the Turkey. Further studies are required for comparing the results of various regions of the country and developing early interventions and treatment facilities.

Determination of health anxiety, anxiety, and somatosensory amplification levels in individuals with normal coronary angiography

The objective of the present study is to determine the somatosensory amplification, anxiety, and depression levels in patients with normal coronary arteries. Thirty-five patients with normal coronary arteries and 35 healthy individuals of similar age and gender as the patient group were included in the study. Somatosensory Amplification Scale (SSAS), Health Anxiety Inventory (HAI-18), Penn State Anxiety Scale (PSWQ), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) were applied to all participants. Comparison of the patient group with the control group demonstrated that SSAS (22.7±8.2; 18.5±5.98; p=0.018), BAI (15.4±9.43; 9.4±7.3; p=0.004), BDI (24.9±13.5; 13.7±7.5; p<0.001), PSWQ (55.3±13.7; 33.8±6.7; p<0.001), and HAI-18 (18.8±8.7; 12.3±7.1; p=0.001) scores were statistically significantly higher in the patient group. Furthermore, a positive correlation was found between SSAS, BAI, BDI, PSWQ, and HAI-18 scores. It was found that concerns about disease prevailed in patients having normal coronary arteries, the patients continued to amplify their somatic sensations, and their anxiety and depression scores were higher than those of healthy individuals. Thus, the necessity of these interventions should be assessed in detail in the future.

Evidence for the changes of pituitary volumes in patients with post-traumatic stress disorder

In pubertal and postpubertal patients with post-traumatic stress disorder (PTSD), significantly greater pituitary gland volumes have been reported. Moving from this point, in the present study, we aimed to investigate pituitary gland volumes in patients with PTSD and hypothesized that volumes of the gland would be structurally changed. Volumetric magnetic resonance imaging of the pituitary gland was performed among sixteen patients with PTSD and fifteen healthy control subjects. We found that the mean volume of the pituitary gland was statistically significant and smaller than that of healthy subjects (0.69±0.08cm³ for patient group and 0.83±0.21 for control subjects). Consequently, in the present study, we found that patients with PTSD had smaller pituitary gland volumes than those of healthy controls like other anxiety disorders. It is important to provide support for this finding in future longitudinal investigations.

Copeptin levels and blood lipid profile in borderline patients with or without self-mutilation

Purpose

Self-mutilation, known as self-harming behaviour of an individual without the intention of suicide, is commonly observed in individuals with borderline personality disorder. The objective of this study is to compare copeptin levels that are known to be related to aggressive behaviour and blood lipid profiles in borderline patients with and without self-mutilation.

Methods

Twenty patients with self-mutilation [SM(+)] and 20 patients without self-mutilation [SM(−)] between the ages of 18 and 49, diagnosed with borderline personality disorder based on DSM-IV-TR(8) diagnostic criteria and attended to by Fırat University Psychiatry Polyclinic, participated in the study. Socio-demographic and clinical data form, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale (HAMA) and Barrat Impulsivity Scale (BIS) were applied to all participants. Copeptin levels and plasma lipid levels were studied in the blood samples taken from the participants.

Results

Mean copeptin level found in SM(+) group (37.54 ± 18.8 ng/mL) was statistically significantly higher than SM(−) group (18.53 ± 16.6 ng/mL) (p = 0.002). A negative correlation was found between mean copeptin and mean total cholesterol levels (r = −0.436; p = 0.005), and between copeptin and low-density lipoprotein cholesterol (LDL) levels (r = −0.403; p = 0.01) in both SM(+) and SM(−) patient groups. HAMA mean score for SM(+) group was found as 36.45 ± 13.2, and for SM(−) group, it was found as 35.7 ± 12.9. There was a statistically significant difference between the depression points achieved by the two groups (p = 0.046). BIS total points average for SM(+) group was determined as 71 ± 9.71, whereas it was determined as 66.8 ± 7.92 in SM(−) group. There was no statistically significant difference between the groups based on anxiety points. Barrat planning, Barrat motor and Barrat attention points for SM(+) group were higher than the SM(−) group. However, the difference was not statistically significant (p > 0.05).

Conclusion

Findings of the study demonstrated that as cholesterol and LDL levels decreased, copeptin levels increased, and that could be related to the self-mutilation behaviour.

Assessment of left ventricle systolic and diastolic functions in schizophrenia patients

The objective of the study was to scrutinize in detail the changes that occur in left ventricle (LV) systolic and diastolic functions using echocardiography in patients with at least 5 years of history and 40 healthy volunteers matching the patients in age and gender, who were enrolled in a cross-sectional study. All cases were examined with Tei Index, an index that could assess LV systolic and diastolic functions in conjuction, and with LV ejection fraction (LVEF) that assesses systolic function. In addition, Mitral E and A wave velocities, Isovolemic relaxation time (IVRT), Tissue Doppler Em (peak early motion) and Am (peak after motion) waves, which evaluate diastolic functions were measured. Tei Index was calculated as 0.61±0.19 in the patient group, and as 0.39±0.10 in the control group and the difference was statistically significant (p<0.001). LVEF was measured as 58%±5 in the patient group, and as 62%±3 in the control group and the difference was statistically significant (p<0.001). Also the IVRT values were significantly different between the tissue Doppler Em and Em/Am ratio among the groups (p<0.001). Echocardiographic myocardial performance, LV systolic and diastolic functions in schizophrenia patients was found to be worse than those of the control group.

Hippocampus and amygdala volumes in patients with vaginismus

AIM: To compare hippocampus and amygdala volumes of patients with vaginismus with those of healthy control subjects.

METHODS: Magnetic resonance imaging was performed on ten patients with vaginismus and ten control subjects matched for age and gender. Volumes of the hippocampus and amygdala were blindly measured.

RESULTS: We found that the mean right amygdala volume of patients with vaginismus were smaller than that of the healthy controls. With regard to hippocampus volumes, the mean left and right hippocampus volumes were smaller than those of the healthy controls.

CONCLUSION: Our present findings suggest that there have been hippocampus and amygdala structural abnormalities in patients with vaginismus. These changes provide the notion that vaginismus may be a fear-related condition.

Subcutaneous Adipose Tissue Type II Deiodinase Gene Expression Reduced in Obese Individuals with Metabolic Syndrome

The present study aimed to evaluate the role of subcutaneous adipose tissue (SAT) type II deiodinase enzyme gene (DIO2) expression in developing metabolic syndrome (MetS). A total of 51 obese patients with MetS and without MetS and 13 healthy subjects enrolled in the study. Body mass index (BMI), waist circumference (WC), waist-to-hip circumference ratio (WHR), hip circumference, and systolic (SBP) and diastolic blood pressures (DBP) of all subjects were recorded. Fasting plasma glucose (FPG), fasting plasma insulin, high density lipoprotein- cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), total cholesterol (TC) and triglyceride (TG) of all subjects were analyzed. Expression of the DIO2 gene in adipose tissue was determined by reverse transcription polymerase chain reaction (qRT-PCR). BMI, WC and WHR were not significantly difference between obese with and without MetS. SBP, DBP, FPG and TG were significantly higher in obese with MetS group than obese without MetS group. While the free triiodothyronine (T3) level was in the normal range in all group, it was significantly lower in the obese with MetS than both obese without MetS and control group. DIO2 expression was significantly lower in the obese with MetS group compared to the control. In correlation analysis, DIO2 expression was negatively correlated with DBP, TG and homeostasis model assessment of insulin resistance (HOMA-IR) levels and positively correlated with free T3. In conclusion, the reduction of SAT DIO2 expression is negatively correlated with DBP and TG levels that are associated with the MetS. This might have an effect on developing MetS. We believe that DIO2 gene may be an important molecular target for future studies in developing targeted treatment options for obese people with MetS.

Association between sociodemographic characteristics and anxiety levels of violence-exposed patients admitted to emergency clinic

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.
