ABSTRACT

Background: Urticaria affects a wide range of daily activities and social relationships. It has a severe impact on quality of life (QOL) and causes psychological problems. Objective: was to assess the impact of chronic urticaria (CU) on quality of sleep, the levels of depression, anxiety, QOL and their interaction with each other and their relation to disease related factors. Patients and methods: The study included 25 patients with CU and 25 healthy controls. Urticaria Activity Score (UAS) was used for objective evaluation of the intensity of urticaria. Patients completed a 10-cm visual analogue score (VAS) indicating the overall severity of their itching over the previous 2 weeks. The Dermatology Life Quality Index (DLQI) was used to evaluate patients' QOL. Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). Pittsburgh Sleep Quality Index (PSQI) was used for evaluation of sleep quality and sleep disturbances. Results: In our CU patients the mean of UAS7 score was 39.72 ± 2.76 and the mean of VAS score was 28 ± 1.34. The mean of DLQI score was 24.8 ± 4.37 indicating severe impact of QOL. CU patients had higher total HADS score when compared to controls; 72% of the patients had depression and 92% had anxiety. By using PSQI, CU patients had significantly longer sleep latency onset, shorter total sleep duration, lower sleep efficiency and higher PSQI scores compared to controls. Conclusion: CU highly affects the QOL of patients and is associated with higher levels of anxiety, depression and poor sleep quality.

ABSTRACT

OBJECTIVE: The aim of the present study was to explore the impact of acute and chronic nicotine consumption on measures of intracortical inhibition and facilitation. METHODS: This study involved 50 chronic heavy cigarette smokers and 40 healthy subjects matched for age, sex and educational level, with no history of chronic nicotine intake. Intracortical inhibition and facilitation were assessed using transcranial magnetic stimulation (TMS) measures of motor threshold (MT), short- and long-interval intra-cortical inhibition (SICI, LICI), cortical silent period (CSP) and intra-cortical facilitation (ICF). Basal serum levels of cotinine were measured in the healthy group and at ½ and 2 h after smoking a single cigarette in the chronic smokers. RESULTS: There was enhanced SICI and reduced ICF in smokers (independent of time after smoking) compared with non-smokers. The former suggests a chronic effect of increased nicotine levels on GABA-A neurotransmission whereas the latter suggests an additional effect on glutamatergic transmission. There were no significant differences between smokers and non-smokers in other TMS parameters. There was a significant negative correlation between cotinine levels at ½â€¯h after smoking and SICI at 3 ms ISI (P < 0.001). There were no significant differences in any of the neurophysiological measures between smokers at ½â€¯h versus 2 h after smoking a single cigarette. CONCLUSION: Chronic nicotine consumption enhances SICI, and reduces ICF, supporting the hypothesis that nicotine acts as a neuromodulator of GABA-A and glutamate neurotransmission.

ABSTRACT

High frequency repetitive transcranial magnetic stimulation (HF-rTMS) over the left dorsolateral prefrontal cortex (L-DLPFC) is a widely applied treatment protocol for chronic smoking and major depressive disorder. However, no previous study has measured the effects of rTMS on both nicotine consumption and anxiety/depression in the same volunteers despite the relationship between them. The aim of this work was to evaluate the efficacy of 10 daily sessions of HF-rTMS over the L-DLPFC in chronic cigarette smokers' addiction and investigate the possible beneficial effects of this treatment procedure on symptoms of depression and anxiety in the same subjects. The study included 40 treatment-seeking nicotine-dependent cigarette smokers. Onset/duration of smoking, number of cigarettes/day, Fagerstrom Test of Nicotine Dependence (FTND), Tobacco Craving Questionnaire-Short Form (TCQ-SF), Hamilton depression and anxiety scales (HAM-D and HAM-A) were recorded. Participants were randomly assigned to the active or the sham treatment group. Those in the active group received 10 trains of 20 Hz stimulation, at 80% of the resting motor threshold (rMT) for 10 consecutive working days over L-DLPFC. Participants were reassessed immediately after treatment, and then 3 months later using all rating scales. There were no differences between active and sham groups at baseline. The cigarette consumption/day, and scores on FTND, and TCQ decreased significantly in both groups (p = 0.0001 for each) immediately after treatment. However, improvement persisted to 3 months in the active group but not in the sham group. Moreover, there was a significant reduction in HAM-D and HAM-A scores immediately after treatment in the active but not the sham group. Subjects with a longer history of smoking had a lower percent improvement in FTND (p = 0.005). Our findings revealed that HF-rTMS over L-DLPCF for 10 days reduced cigarette consumption, craving, dependence, and improved associated symptoms of anxiety and depression.ClinicalTrials.gov Identifier: NCT03264755 registered at 29/08/2017.

ABSTRACT

Transcranial magnetic stimulation (TMS) can be used to evaluate the effects of pharmacological interventions. The aim of this study was to assess the impact of the selective serotonin reuptake inhibitor, sertraline, and the atypical antipsychotic drugs quetiapine and olanzapine, on cortical excitability in unmedicated patients with major depressive disorder (MDD). The study included 45 medication-free MDD patients diagnosed according to DSM V. They were divided randomly into three groups who received a single oral dose of one of the three drugs sertraline (50 mg), quetiapine (100 mg) and olanzapine (10 mg). Psychological evaluation was conducted using the Mini-Mental State Examination (MMSE) and Beck Depression Inventory Scale (BDI). Resting and active motor thresholds (rMT and aMT) together with contralateral and ipsilateral cortical silent periods (cSP, and iSP) were measured for each participant before and at the time of maximum concentration of drug intake. There was significant increase in excitability of motor cortex after sertraline without changes in GABAB neurotransmission. Quetiapine and olanzapine potentiated inhibitory GABAB neurotransmission (prolongation of cSP); olanzapine additionally prolonged the iSP. Thus TMS can differentiate between the impact of different psychotropic drugs on excitatory and inhibitory transmission in motor cortex.

ABSTRACT

BACKGROUND: Acne vulgaris is a common cosmetic problem that is frequently associated with psychosocial disturbances as well as increased oxidative stress. However, oxidative stress and psychological aspects have been studied separately in acne. OBJECTIVE: To evaluate the relationships between oxidative stress, anxiety, depression, and quality of life in acne patients. METHODS: Sixty patients with facial acne and 40 age- and sex-matched healthy individuals were included in the study. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS), and quality of life (QoL) was measured by the Cardiff Acne Disability Index. Disease severity was assessed using the Combined Acne Severity Classification. The serum levels of zinc and malondialdehyde (MDA) and total antioxidant capacity (TAC) were measured in patients and healthy subjects. RESULTS: The mean HADS scores for anxiety and depression were higher in patients than controls (P<.001 for both). Acne patients showed higher serum MDA and lower TAC and serum zinc levels compared with control subjects (P=.019, P<.001, and P=.028, respectively). Anxiety and depression scores did not correlate with oxidative stress parameters. Patients with moderate/severe acne had worse anxiety scores than mild acne (P=.048), and higher anxiety scores were associated with poorer quality of life (r=.436, P=.001). CONCLUSION: Our results indicate that the high levels of anxiety and depression in patients with facial acne were not related to oxidative stress. Anxiety was more common than depression and was directly related to QoL impairment.

ABSTRACT

BACKGROUND: Addiction to tramadol, a widely used analgesic, is becoming increasingly common. Tramadol can also induce seizures even after a single clinical dose. We tested whether the epileptogenicity of tramadol was associated with any changes in cortical excitability and inhibitory transmission using transcranial magnetic stimulation (TMS). METHODS: The study included 16 tramadol dependent patients and 15 age and sex matched healthy volunteers. Clinical evaluation was conducted using an addiction severity index. TMS assessment of excitability was conducted on the motor cortex since the response to each TMS pulse at that site is easily measured in terms of the amplitude of the twitches it evokes in contralateral muscles. Measures included resting and active motor threshold (RMT and AMT respectively), motor evoked potential (MEP) amplitude, cortical silent period (CSP) duration, transcallosal inhibition (TCI), and short interval intracortical inhibition and facilitation (SICI and ICF respectively). Urinary level of tramadol was measured immediately before assessing cortical excitability in each patient. RESULTS: RMT and AMT were significantly lower, the duration of the CSP was shorter and SICI was reduced in patients compared with the control group. These findings are suggestive of increased neural excitability and reduced GABAergic inhibition following exposure to tramadol. Also there were negative correlations between the severity of tramadol dependence and a number of cortical excitability parameters (AMT, RMT, and CSP with P=0.002, 0.005, and 0.04 respectively). CONCLUSIONS: The results provide evidence for hyperexcitability of the motor cortex coupled with inhibitory deficits in tramadol dependent patients.

ABSTRACT

BACKGROUND: There are only a few reports which provide prevalence rates of mild cognitive impairment (MCI) and dementia specifically in Arabic countries. OBJECTIVE: This study is aimed at estimating the prevalence of MCI and dementia among subjects aged ≥60 years using door-to-door survey in Qena Governorate/Egypt. METHODS: We conducted a door-to-door survey with multistage probability random sampling. Screening of all subjects aged ≥60 years (n = 691) employed a simple questionnaire including changes in memory, behavior, and daily activity, Memory and Executive Screening test (MES)as well as the Mini-Mental State Examination. Suspected cases were referred to the hospital for full clinical examination, DSM-IV diagnostic criteria, Hachinski Ischemic Score, neuroimaging, and laboratory investigations if indicated. RESULTS: Of the 691 participants, 12 cases had MCI, giving a crude prevalence rate (CPR) of 1.74/100 and 35 were identified as positive for dementia with a CPR of 5.07/100. The highest age-specific prevalence rates were recorded among subjects ≥85 years old (100/100). The CPRs were significantly higher in urban than rural areas (7.1 versus 3.27/100, respectively; p = 0.03), in industrial areas than non-industrial areas (13.23 versus 1.99; p = 0.00001), and in illiterate than literate participants (10.12 versus 2.25/100; p = 0.00001). CONCLUSION: Overall, the prevalence rate of MCI and dementia were lower in Qena/Egypt than in other countries. Advanced age, illiteracy, and living in an industrial area were found to be associated with dementia.

ABSTRACT

BACKGROUND: The purpose of this study was to investigate the long-term efficacy of transcranial direct current stimulation (tDCS) in the neurorehabilitation of Alzheimer's disease (AD). METHODS: Thirty-four AD patients were randomly assigned to three groups: anodal, cathodal, and sham tDCS. Stimulation was applied over the left dorsolateral prefrontal cortex for 25 min at 2 mA, daily for 10 days. Each patient was submitted to the following psychometric assessments: mini-mental state examination (MMSE) and Wechsler adult intelligence scale-third edition at base line, at the end of the 10th sessions and then at 1 and 2 months after the end of the sessions. Motor cortical excitability and the P300 event-related potential were assessed at baseline and after the last tDCS session. RESULTS: Significant treatment group × time interactions were observed for the MMSE and performance IQ of the WAIS. Post hoc comparisons showed that both anodal and cathodal tDCS (ctDCS) improved MMSE in contrast to sham tDCS. Whereas, this was only true for ctDCS in the performance IQ. Remarkably, tDCS also reduced the P300 latency, but had no effect on motor cortex excitability. CONCLUSION: Our findings reveal that repeated sessions of tDCS could not only improve cognitive function but also reduce the P300 latency, which is known to be pathologically increased in AD.
