ObjectiveThe relationship between platelet activation and psychiatric disorders has been shown in previous work. Mean platelet volume (MPV) is a measure of platelet size and a good indicator of platelet activity, which increases in cardiovascular diseases (CVDs). It is known that anxiety is a considerable factor in the etiology of mortality in CVDs. The aim of the present study was to investigate any probable difference in the MPV of patients with panic disorder (PD).MethodsSixty-one drug-free patients, aged 18–65 years and diagnosed with PD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, were included in the study, along with 63 healthy age- and sex-matched volunteers. The body mass index (BMI) was calculated and MPV measured for each subject.ResultsThe MPV was found to be higher in the PD group compared to the control group (P=0.004). There were no significant differences between the two groups in terms of platelet count or BMI.ConclusionAlterations in platelet activity may be a reflection of abnormal 5-hydroxytryptamine (5-HT) 1A receptor function in the central nervous system of subjects with a diagnosis of PD. These findings may elucidate the relationship between CVDs and PD. The findings of the present study suggest that MPV is increased in PD patients.
BackgroundAs the relationship between psychological stress and platelet activation has been widely studied in recent years, activated platelets lead to certain biochemical changes, which occur in the brain in patients with mental disorders. However, data relating to the mean platelet volume (MPV) in patients with panic disorder (PD) are both limited and controversial. Herein, we aimed to evaluate, for the first time, the red cell distribution width (RDW) levels combined with MPV levels in patients with PD.Patients and methodsBetween January 2012 and June 2015, data of 30 treatment-naïve patients (16 females, 14 males; mean age: 37±10 years; range: 18–59 years) who were diagnosed with PD and 25 age- and sex-matched healthy volunteers (10 females, 15 males; mean age: 36±13 years; range: 18–59 years) (control group) were retrospectively analyzed. The white blood cell count (WBC), MPV, and RDW levels were measured in both groups.ResultsThe mean WBC, MPV, and RDW levels were 9,173.03±2,400.31/mm3, 8.19±1.13 fl, and 12.47±1.14%, respectively, in the PD group. These values were found to be 7,090.24±1,032.61, 6.85±0.67, and 11.63±0.85, respectively, in the healthy controls. The WBC, MPV, and RDW levels were significantly higher in the patients with PD compared to the healthy controls (P=0.001, P=0.001, and P=0.003, respectively). However, there was no significant difference in the platelet number between the patients with PD and healthy controls (P>0.05).ConclusionOur study results are the first to demonstrate that the RDW levels combined with MPV levels significantly increase among patients with PD. We believe that increased RDW and MPV levels can be used as a novel marker for PD.
ObjectiveFactors affecting pain sensation are still being investigated. In this study, we aimed to examine the effects of sex, age, body mass index (BMI), somatosensory amplification, anxiety, and depression on the perception of pain.MethodsVenipuncture was performed on 140 healthy individuals. All the cases completed a sociodemographic data form, visual analog scale (VAS), Beck Anxiety Inventory (BAI), Beck Depression Inventory, and Somatosensory Amplification Scale. Height and weight were also measured.ResultsWhen both the sexes were compared, there was no difference in terms of VAS, BMI, age, and Beck Depression Inventory, but Somatosensory Amplification Scale and BAI were found to be higher in females. A correlation was found among VAS points, BAI, and BMI. The results of a regression analysis show that the BAI score is a predictor for the VAS score.ConclusionThese results indicate that anxiety may be a predictor of pain, whereas sex, depression, somatosensory amplification, age, and weight do not appear to influence the perception of pain.
Background:Crowded hospital outpatient clinics and endless waiting lines that make patients feel overlooked tend to exaggerate patients’ anxiety levels. In addition, fear of pain, shyness, religious and traditional thoughts, women’s sexual role in society, and previous information and experience also contribute to people’s anxiety levels with regard to gynecologic examination.Objectives:We aimed to analyze the effect of specific information about gynecologic examination on anxiety levels of women applying to gynecology clinics.Materials and Methods:In this randomized prospective study, the women applying for a gynecological examination were randomly allocated into control, intervention 1, and intervention 2 groups. Power analysis indicated that in order to achieve a one-point decrease from the previous anxiety score of 43.85 ± 5.41 at one side alpha 0.05 with a power of 80%, at least 79 women were needed in each group. Four medical school students interviewed 75 women (25 in control, 25 in intervention 1, and 25 in intervention 2). The data were collected using the demographic, social, and economic data form, and the Turkish version of the state-trait anxiety inventory (STAI). The women in the intervention 1 and 2 groups were instructed to read a paper that contained brief information about the gynecological examination procedure and the profits obtained from forests, respectively. All participants, including the women in the control group, filled the STAI by themselves. The three groups were compared appropriately.Results:The demographics pertaining to age, gravidity and parity, miscarriage, induced abortion, ectopic pregnancy, offspring number, place of residence, working status, education level and previous experience of gynecological examination did not differ among the groups (P > 0.05). According to the STAI scores, all groups had mild state (control: 40.20 ± 10.53, intervention 1: 42.00 ± 11.98, and intervention 2: 39.53 ± 10.32) and severe continuous (control: 46.78 ± 8.65, Intervention 1: 47.25 ± 9.57, and intervention 2: 46.60 ± 9.72) anxiety levels. However, both state and continuous anxiety scores were not significantly different in all groups (P > 0.05).Conclusions:Providing brief written information about the gynecological examination procedure and the clinic’s working discipline is not sufficient to lower the anxiety of women applying for a gynecological examination.
Venlafaxine is the first antidepressant that acts via inhibiting serotonin and noradrenaline reuptake. Hypertension is observed in doses exceeding 300 mg/day and is the most feared complication. We report a patient with accelerated hypertension after venlafaxine use observed at a dose of 150 mg/day. A 23-year-old patient with symptoms of insomnia, depression, anhedonia, fatigue admitted our clinic. Venlafaxine at a dose of 75 mg/day was initiated after he was diagnosed with major depressive disorder. After 5 months, venlafaxine dose was uptitrated to 150 mg/day due to inadequate response to drug. After using venlafaxine for ten months at the dose of 150 mg/day, he admitted our clinic with headache and epistaxis. He was hospitalized after his blood pressure was measured as 210/170 mmHg. No secondary causes for hypertension were found, and venlafaxine treatment was considered possible etiologic factor. After stopping venlafaxine treatment, his blood pressure was reverted back to normal limits. While mild elevation of blood pressure could be observed after venlafaxine treatment, this case shows that accelerated hypertension with a diastolic blood pressure rise above 120 mmHg could be observed at relatively low doses of venlafaxine. Close monitoring of blood pressure is necessary after initiation of treatment, as accelerated hypertension could cause endorgan damage with potentially catastrophic results.
Introduction: The aim was to investigate the relation between sociodemographic features, anxiety, depression, sleep quality, childhood trauma experiences, and quality of life and bruxism determining the risk factors in people with bruxism. Methods: A total of 200 people were included in the study. Of the patients, 100 were diagnosed with bruxism and 100 were included in the control group. Sociodemographic Data Form, Hospital Anxiety Depression Scale (HAD), The Pittsburgh Sleep Quality Index (PSQI), Childhood Trauma Scale (CTS), Short Form-36 Quality of Life Scale (SF-36) were used. Results: While there was no significant difference between the case group and the control group in terms of age, gender, marital status, and working status, there was a significant difference between educational levels. When the groups were compared a significant difference was found with regard to HAD-A (p<0.05), HAD-D (p<0.01), PSQI (p<0.01) and CTS (p<0.05) scores. While a significant difference was found when KF-36 subscales were examined, with regard to Physical Function (p<0.01), Pain (p<0.05), Social Function (p<0.05) and Mental Health (p<0.01) scores, no significant difference was detected between the subscales of Role Strength (p>0.05), General Health (p>0.05), Vital Energy (p>0.05) and Emotional Role (p>0.05). Regression analysis shows, (PSQI), HAD-D CTS scores predicted bruxism. Conclusion: Higher depression scale scores, bad sleep quality, traumatic childhood experiences increase the risk for bruxism. Paying attention to the mental state of people diagnosed with bruxism in the treatment process and incorporating the psychiatrists in this process may increase the success rate of the treatment.
BackgroundAlzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative diseases. Recent studies have sought to identify precursor symptoms of AD and PD that occur before the onset of the disease. We evaluated changes in the oral mucosa of patients with AD and PD using a stereological method.Patients and methodsThe study included 29 patients with AD, 30 patients with idiopathic PD, and 30 healthy volunteers. Brush biopsies were obtained from all participants, and the nucleator method was used to estimate the volume of cells obtained from the buccal mucosa.ResultsCytomorphometric analysis revealed that the nuclear volume was 484.39±117.10 µm3 in the AD group, 509.71±132.26 µm3 in PD patients, and 509.30±100.21 µm3 in the control group. The cytoplasmic volume was 115,456.60±30,664.98 µm3 in the AD group, 103,097.93±25,034.65 µm3 in PD patients, and 109,528.45±28,381.43 µm3 in the control group. The nuclear and cytoplasmic volumes were not significantly different among groups (P>0.05).ConclusionThe cytomorphometric analysis revealed no significant differences in the cytoplasmic and nuclear volumes of buccal cells obtained from patients with AD and PD and healthy volunteers.
