Multiple Keratoacanthoma-like Syndromes: Case Report and Literature Review.

Keratoacanthoma (KA) is a fast-growing skin tumor subtype that can be observed as a solitary lesion or rarely as multiple lesions in the context of rare genetic syndromes. Syndromes with multiple keratoacanthoma-like lesions have been documented as multiple self-healing squamous epithelioma (Ferguson-Smith syndrome), eruptive keratoacanthoma of Grzybowski, multiple familial keratoacanthoma of Witten and Zak Muir-Torre syndrome, and incontinentia pigmenti. The treatment approach of those entities is challenging due to the numerous lesions, the lesions' undefined nature, and the co-existence of other malignant skin tumors. Herein, we report a case of a 40-year-old woman who developed multiple treatment-resistant Ferguson-Smith-like keratoacanthomas with a co-existing large and ulcerated invasive squamous cell carcinoma and microcystic adnexal carcinoma on the scalp. Multiple keratoacanthomas on her extremities were successfully treated with oral acitretin (0.5 mg/kg/day) in combination with topical Fluorouracil (5-FU) 5%, while excision and plastic surgery restoration were performed to treat the ulcerated cancer lesion on her scalp. Due to the interesting nature of this rare syndrome, we performed a literature review including case reports and case series on multiple-KA-like lesions syndromes and focusing on diagnosis and therapy approaches. We also conducted a comparison of patient reports, which included assessing the clinical appearance of the lesions and evaluating the success and progress or the failure of various treatment approaches that were implemented.

Psychiatric disorders and SLC6A4 gene variants: possible effects on alcohol dependence and alzheimer's disease.

Serotoninergic system is one of the most important neurotransmission systems investigated in the field of psychiatry. Extensive evidence reveals how alterations of this system, and especially of the SLC6A4 gene, may be associated with psychiatric disorders. In this study we aimed to evaluate the pleiotropic nature of SLC6A4 alterations and their association with the overall risk of brain diseases rather than disorder-specific. SLC6A4 variants, namely 5HTTLPR, STin2, rs2066713, rs25531, rs4251417, rs6354 and rs7224199 were investigated in 4 independent cohorts of subjects with specific psychiatric disorders, including Alcohol dependence disorder (ALC), Alzheimer disease (ALZ), Schizophrenia (SCZ) and Bipolar disorder (BPD). Other variables (biochemical parameters and Psychiatric scales scores) were also tested for association. SLC6A4 polymorphisms are not associated with the risk of developing major psychiatric disorders (SCZ and BPD); however some signals were detected in ALC (HTTLPR pd = 9.25 × 10-03, pr = 7.24 × 10-03; rs2066713 pd = 6.35 × 10-08; rs25531 pd = 2.95 × 10-02; rs4251417 pd = 2.46 × 10-03), and ALZ (rs6354 pr = 1.22 × 10-02; rs7224199 pd = 1.00 × 10-08, pr = 2.65 × 10-02) cohorts. Some associations were also observed on exploratory analyses. Our findings did not reveal any major influence on SCZ and BPD development; On the other hand, some alteration of the SLC6A4 sequence were associated with an increased risk of ALC and ALZ disorders, suggesting common pathways. The results of this study should be carefully interpreted since it suffers of some inherent limitations (e.g. cohort size, slight ethnic heterogeneity). Further analyses may provide better detail on the molecular processes behind SLC6A4 alterations.

Beneficial Effect of Flecainide Controlled Release on the Quality of Life of Patients with Atrial Fibrillation-the REFLEC-CR Study.

PURPOSE: Atrial fibrillation (AF) is the most common cardiac arrhythmia with a considerable impact on patients' quality of life (QoL). METHODS: This prospective, multicenter, observational study aimed to evaluate the effect of oral treatment with controlled-release (CR) flecainide on AF patients' QoL and treatment compliance during a 12-week period. A total of 70 sites enrolled consecutive patients with paroxysmal (PAF) or persistent AF (PerAF), treated with flecainide CR in the context of a rhythm control strategy. The effect on QoL was assessed by the Canadian Cardiovascular Society Severity of Atrial Fibrillation scale (CCS-SAF). RESULTS: In total, 679 patients (53.2% females, 66 ± 11.7 years, 86.9% PAF) were included. Prior antiarrhythmic medication had been administered in 43.8% of patients. A daily dose of 200 mg was administered to 66.4% of patients by the end of study. Flecainide CR resulted in a significant reduction in the CCS-SAF score (mean (SD)) at the end of the study as compared with baseline (1.32 (0.57) vs 1.64 (0.73), p < 0.0001). Flecainide CR significantly reduced the CCS-SAF score both in PAF (1.27 (0.52) vs 1.61 (0.72), p < 0.0001) as well as in PerAF (1.63(0.77) vs 1.84(0.81), p = 0.017). Overall, 4 (0.6%) patients experienced a total of 6 adverse events during the study period. The compliance to flecainide CR treatment was very high with 93.6% of patients responding that they had not missed any dose during the study period. CONCLUSION: Treatment with flecainide CR significantly improves QoL in both paroxysmal as well as persistent AF patients, with an excellent safety profile and associated patient compliance.

Impact of sex and reproductive status on memory circuitry structure and function in early midlife using structural covariance analysis.

Research on age-related memory alterations traditionally targets individuals aged ≥65 years. However, recent studies emphasize the importance of early aging processes. We therefore aimed to characterize variation in brain gray matter structure in early midlife as a function of sex and menopausal status. Subjects included 94 women (33 premenopausal, 29 perimenopausal, and 32 postmenopausal) and 99 demographically comparable men from the New England Family Study. Subjects were scanned with a high-resolution T1 sequence on a 3 T whole body scanner. Sex and reproductive-dependent structural differences were evaluated using Box's M test and analysis of covariances (ANCOVAs) for gray matter volumes. Brain regions of interest included dorsolateral prefrontal cortex (DLPFC), inferior parietal lobule (iPAR), anterior cingulate cortex (ACC), hippocampus (HIPP), and parahippocampus. While we observed expected significant sex differences in volume of hippocampus with women of all groups having higher volumes than men relative to cerebrum size, we also found significant differences in the covariance matrices of perimenopausal women compared with postmenopausal women. Associations between ACC and HIPP/iPAR/DLPFC were higher in postmenopausal women and correlated with better memory performance. Findings in this study underscore the importance of sex and reproductive status in early midlife for understanding memory function with aging.

Alzheimer's Disease and Neurotransmission Gene Variants: Focus on Their Effects on Psychiatric Comorbidities and Inflammatory Parameters.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative disorder accounting for 60-70% of dementia cases. Genetic origin accounts for 49-79% of disease risk. This paper aims to investigate the association of 17 polymorphisms within 7 genes involved in neurotransmission (COMT, HTR2A, PPP3CC, RORA, SIGMAR1, SIRT1, and SORBS3) and AD. METHODS: A Greek and an Italian sample were investigated, for a total of 156 AD subjects and 301 healthy controls. Exploratory analyses on psychosis and depression comorbidities were performed, as well as on other available clinical and serological parameters. RESULTS: AD was associated with rs4680 within the COMT gene in the total sample. Trends of association were found in the 2 subsamples. Some nominal associations were found for the depressive phenotype. rs10997871 and rs10997875 within SIRT1 were nominally associated with depression in the total sample and in the Greek subsample. rs174696 within COMT was associated with depression comorbidity in the Italian subsample. DISCUSSION: Our data support the role of COMT, and particularly of rs4680, in the pathogenesis of AD. Furthermore, the SIRT1 gene seems to modulate depressive symptomatology in the AD population.

Problem Gambling in Greece: Prevalence and Risk Factors During the Financial Crisis.

In Greece no study has ever been conducted on the prevalence of problem gambling. Therefore, a cross-sectional survey was carried out amid the recession aiming to (1) estimate past year prevalence of problem gambling, (2) explore socio-economic and demographic differences among gamblers and non gamblers, (3) explore socio-economic and demographic differences among gamblers who started gambling prior and during the downturn and (4) identify its risk factors with a special interest in the influence of the recession. To this end, data emanating from a telephone and patron survey were combined. A random and representative sample of 3.404 people participated in the telephone survey and 2.400 in the patron survey. The interview schedule was the same in both studies. The presence of problem gambling was assessed with the Canadian Problem Gambling Index. Information on participants' socio-economic and demographic characteristics as well as their ways of dealing financially with the crisis were collected. Findings indicated that 2.4% of respondents met criteria for problem gambling. Male gender, minority status, living with family of origin, low educational level and low to zero income were found to constitute the risk factors of the disorder. Moreover, having started gambling during the recession increased the odds of suffering from problem gambling; however this finding was gender-specific. Thus, people end up in problem gambling through various pathways, with these trajectories being different for men and women. Any intervention should address the complexity of the issue and be tailored by gender.

Major Depression and the Degree of Suicidality: Results of the European Group for the Study of Resistant Depression (GSRD).

Background: This European multicenter study aimed to elucidate suicidality in major depressive disorder. Previous surveys suggest a prevalence of suicidality in major depressive disorder of ≥50%, but little is known about the association of different degrees of suicidality with socio-demographic, psychosocial, and clinical characteristics. Methods: We stratified 1410 major depressive disorder patients into 3 categories of suicidality based on the Hamilton Rating Scale for Depression item 3 (suicidality) ratings (0=no suicidality; 1-2=mild/moderate suicidality; 3-4=severe suicidality). Chi-squared tests, analyses of covariance, and Spearman correlation analyses were applied for the data analyses. Results: The prevalence rate of suicidality in major depressive disorder amounted to 46.67% (Hamilton Rating Scale for Depression item 3 score ≥1). 53.33% were allocated into the no, 38.44% into the mild/moderate, and 8.23% into the severe suicidality patient group. Due to the stratification of our major depressive disorder patient sample according to different levels of suicidality, we identified some socio-demographic, psychosocial, and clinical variables differentiating from the patient group without suicidality already in presence of mild/moderate suicidality (depressive symptom severity, treatment resistance, psychotic features, add-on medications in general), whereas others separated only when severe suicidality was manifest (inpatient treatment, augmentation with antipsychotics and benzodiazepines, melancholic features, somatic comorbidities). Conclusions: As even mild/moderate suicidality is associated with a failure of achieving treatment response, adequate recognition of this condition should be ensured in the clinical practice.

Adolescent gambling in greater Athens area: a cross-sectional study.

PURPOSE: Problem gambling in adolescents has recently emerged as a pressing public health concern. In this context and in light of the pervasive financial crisis in Greece, the present study aimed to explore adolescents' gambling involvement in Athens region to estimate the prevalence of its problematic form and to identify its risk/protective factors. METHODS: A total of 2141 students were recruited from a representative sample of 51 schools located in greater Athens area. The presence of problem gambling was assessed through the use of the DSM-IV-MR-J questionnaire. Data were collected in the form of a self-reported questionnaire during one school hour. RESULTS: Results indicate that 1-year prevalence of high severity problem gambling was found to be 5.6%. Regarding the risk factors for problem gambling; male gender, parental engagement with gambling activities, living without the parents, low grades at school, foreign nationality and the referent absence of availability of food in the household, increased the risk of suffering from the disorder. CONCLUSION: Gambling behavior among adolescents constitutes a problem in Greece and highlights the need for designing and implementing appropriate preventive interventions, especially amid the ongoing financial crisis.

Combined DTI-fMRI Analysis for a Quantitative Assessment of Connections Between WM Bundles and Their Peripheral Cortical Fields in Verbal Fluency.

Diffusion tensor imaging (DTI) tractography and functional magnetic resonance imaging (fMRI) are powerful techniques to elucidate the anatomical and functional aspects of brain connectivity. However, integrating these approaches to describe the precise link between structure and function within specific brain circuits remains challenging. In this study, a novel DTI-fMRI integration method is proposed, to provide the topographical characterization and the volumetric assessment of the functional and anatomical connections within the language circuit. In a group of 21 healthy elderly subjects (mean age 68.5 ± 5.8 years), the volume of connection between the cortical activity elicited by a verbal fluency task and the cortico-cortical fiber tracts associated with this function are mapped and quantified. An application of the method to a case study in neuro-rehabilitation context is also presented. Integrating structural and functional data within the same framework, this approach provides an overall view of white and gray matter when studying specific brain circuits.

Anxiety and depression among Greek men with primary erectile dysfunction and premature ejaculation.

BACKGROUND: Erectile dysfunction (ED) and premature ejaculation (PE) are the two most prevalent sexual disorders among males associated with significant distress and impairment in quality of life. The aim of this study was to investigate the prevalence of anxiety and depression symptoms among patients with primary ED and PE. METHODS: A sample of 57 men (ED = 31; PE = 26) were compared to 25 male outpatients with anxiety disorder (AD) and 25 healthy controls. Principal assessment measures included the State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI). RESULTS: Greater levels of STAI state anxiety were reported among the ED, PE, and AD groups as compared to healthy controls. In contrast ED and AD groups scored higher than controls on the STAI trait anxiety and BDI, but PE scores were not different from healthy controls in both measures. CONCLUSIONS: The study findings suggest that both primary ED and PE are conditions associated with significant state anxiety; however, PE appears to be less associated with trait anxiety and depression compared to ED, a finding that corroborates the recent acknowledgement of PE as a more biologically based condition. Limitations and potential clinical implications are also discussed.

Baseline heartbeat perception accuracy and short-term outcome of brief cognitive-behaviour therapy for panic disorder with agoraphobia.

BACKGROUND: Increased heartbeat perception accuracy (HBP-accuracy) may contribute to the pathogenesis of Panic Disorder (PD) without or with Agoraphobia (PDA). Extant research suggests that HBP-accuracy is a rather stable individual characteristic, moreover predictive of worse long-term outcome in PD/PDA patients. However, it remains still unexplored whether HBP-accuracy adversely affects patients' short-term outcome after structured cognitive behaviour therapy (CBT) for PD/PDA. AIM: To explore the potential association between HBP-accuracy and the short-term outcome of a structured brief-CBT for the acute treatment of PDA. METHOD: We assessed baseline HBP-accuracy using the "mental tracking" paradigm in 25 consecutive medication-free, CBT-naive PDA patients. Patients then underwent a structured, protocol-based, 8-session CBT by the same therapist. Outcome measures included the number of panic attacks during the past week, the Agoraphobic Cognitions Questionnaire (ACQ), and the Mobility Inventory-Alone subscale (MI-alone). RESULTS: No association emerged between baseline HBP-accuracy and posttreatment changes concerning number of panic attacks. Moreover, higher baseline HBP-accuracy was associated with significantly larger reductions in the scores of the ACQ and the MI-alone scales. CONCLUSION: Our results suggest that in PDA patients undergoing structured brief-CBT for the acute treatment of their symptoms, higher baseline HBP-accuracy is not associated with worse short-term outcome concerning panic attacks. Furthermore, higher baseline HBP-accuracy may be associated with enhanced therapeutic gains in agoraphobic cognitions and behaviours.

Correlation between depression, anxiety, and polymorphonuclear cells' resilience in ulcerative colitis: the mediating role of heat shock protein 70.

BACKGROUND: To investigate whether anxiety and depression levels are associated with Heat Shock Protein 70 (HSP70) induction in the colon of patients with ulcerative colitis (UC). METHODS: The design was cross-sectional. Clinical activity was assessed by the Rachmilewitz Index (CAI). Three psychometric questionnaires were used: Zung Depression Rating Scale (ZDRS), Spielberg State-Trait Anxiety Inventory (STAI), Hospital Anxiety and Depression Scale (HADS). Colon biopsies were obtained from each affected anatomical site. Severity of inflammation was assessed by eosin/hematoxylin. Constitutive (HSP70c) and inducible (HSP70i) HSP70 expression were immunohistochemically studied. RESULTS: 29 UC patients were enrolled (69% men). Mean age was 46.5 years (SD: 19.5). Inflammation severity was moderate in 17 patients, severe in 6, and mild in 6. The mean number of years since diagnosis was 7.9 (SD: 6.5). The mean CAI was 6.4 (SD: 3.1). In active UC, there was downregulation of HSP70c in inflamed epithelium, without significant HSP70 induction. In 22/29 cases of active cryptitis, polymorphonuclear cells (PMN) clearly expressed HSP70i, with weak, focal positivity in the other 7 cases. Except for the hospital anxiety scale, scores in all psychometric tools were higher in patients with strong HSP70i immunoreactivity in the PMN. Logistic regression showed a strong positive relationship between HSP70i immunoreactivity in the PMN cells and scores in the trait anxiety, ZDRS, and hospital depression scales, (Odds ratios 1.3, 1.3, and 1.5; P = 0.018, 0.023, and 0.038; Wald test, 5.6, 5.2, and 4.3 respectively) and a weaker but significant positive correlation with the CAI (Odds ratio 1.654; P = 0.049; Wald test 3.858). CONCLUSION: HSP70 is induced in PMN cells of UC patients and its induction correlates with depression and anxiety levels.

Cytokines, diabetes mellitus and psychopathology: a challenging combination.

OBJECTIVES: The aim of this study was to investigate the association of IL-6, IL-12, and TNF-α with trait and state psychological factors in type 2 diabetic patients. DESIGN: Patients were divided in two groups. Group A consisted of 86 controlled diabetic patients (HbA1c<7) and the Group B consisted of 45 uncontrolled diabetic patients (HbA1c ≥ 7). SETTINGS: During the initial phase of the study (T0), blood samples were taken for measuring IL-6, IL-12 and TNF-α serum levels as well as a battery of psychometric instruments. One year later (T1), the uncontrolled diabetic patients were re-evaluated with the use of the same psychometric instruments and with the identical blood analysis. RESULTS: The average values of tnf-α were significantly different among controlled (7.73 ± 5.51) and uncontrolled patients (9.29 ± 4.52) at a significance level of 5% (p=0.009). Controlled diabetic patients show a statistically significant relationship between IL-6 and neuroticism (rp=0.303, p=0.010), and between IL-12 and psychotism, (rsp=0.382, p=0.001). Controlled diabetic patients show a statistically significant relationship between IL-12 and the act out hostility (rsp=-0.307, p=0.009). The scores of the psychometric tests differ significantly between the first and second evaluation. Acting out hostility and the direction of hostility increased when HbA1c values fell below the threshold of 7, while the total hostility index, as well as all other scales, dropped when patients controlled their metabolic profile. CONCLUSIONS: The present results provide evidence that IL-6, IL-12 and TNF-α are closely related to the course and treatment of type 2 diabetes.

Rejection attitudes, poor parental bonding, and stressful life events in heroin addicts' families.

BACKGROUND: The influence of family factors on the development and/or on maintenance of heroin addiction still remains unclear. OBJECTIVES: The aim of this study was to investigate family factors, which might be associated with heroin addiction in a sample of male individuals. METHODS: A group of 40 heroin addicts' families was compared with a group of 17 families with a member presenting schizophrenia and a group of 27 families with mentally healthy members in regard to (1) parents' rejection attitudes toward their adult child, (2) quality of parental bond, as perceived by the adult child, and (3) stressful life events in the nuclear family. RESULTS: The main findings showed that the degree of rejection by the fathers in the heroin addicts' families as well as in the subjects with schizophrenia was significantly higher compared to the fathers' degree of rejection in the control group. Moreover, the degree of rejection by mothers in the heroin addicts' families was significantly higher compared to the mothers' degree of rejection in the control group. Heroin addicts reported that they had perceived less care from their fathers than healthy controls. The total number of stressful life events in the nuclear family was higher in the patients with schizophrenia in comparison to the healthy controls. Also, in the heroin addicts' group, a significantly higher number of fathers presented a current or past psychiatric disorder. CONCLUSIONS: The findings of this study showed the importance of negative family factors in the course of heroin addiction.

Comorbid attention-deficit/hyperactivity disorder in adult psychiatric outpatients with depressive or anxiety disorders.

BACKGROUND: There are very few studies reporting on the prevalence and the contribution of not previously diagnosed ADHD in the clinical picture of other psychiatric disorders. The aim of our study is to determine the prevalence and clinical correlates of comorbid attention deficit/hyperactivity disorder (ADHD) in adult psychiatric outpatients with depressive or anxiety disorders. METHODS: During a 6-month period, 114 outpatients with depressive or anxiety disorders were evaluated for ADHD diagnosis. Assessment included interviews with both patient and relatives/friends and the use of a daily diary. Moreover, the patients completed the self-report scales Beck Depression Inventory (BDI), Spielberger's Anxiety Inventory (STAI), and the Symptom Checklist-90-R Rating Scale (SCL-90-R). RESULTS: A total of 22 out of 114 patients (19.3%) received an ADHD diagnosis for the first time in their life. Comorbid ADHD compared to non ADHD patients scored significantly higher (p < 0.05) for depression (BDI), state and trait anxiety (STAI) and in the following SCL-90-R factors: Positive Symptoms Distressing Index, Positive Symptoms Index, Somatization, Obsessive Compulsive, Depression, Anxiety, and Hostility. CONCLUSIONS: ADHD might go unrecognized among psychiatric outpatients. Patients with depressive or anxiety disorder reporting more severe symptomatology should be carefully screened for possible comorbid adult ADHD.

Investigating the structural network underlying brain-immune interactions using combined histopathology and neuroimaging: a critical review for its relevance in acute and long COVID-19.

Current views on immunity support the idea that immunity extends beyond defense functions and is tightly intertwined with several other fields of biology such as virology, microbiology, physiology and ecology. It is also critical for our understanding of autoimmunity and cancer, two topics of great biological relevance and for critical public health considerations such as disease prevention and treatment. Central to this review, the immune system is known to interact intimately with the nervous system and has been recently hypothesized to be involved not only in autonomic and limbic bio-behaviors but also in cognitive function. Herein we review the structural architecture of the brain network involved in immune response. Furthermore, we elaborate upon the implications of inflammatory processes affecting brain-immune interactions as reported recently in pathological conditions due to SARS-Cov-2 virus infection, namely in acute and post-acute COVID-19. Moreover, we discuss how current neuroimaging techniques combined with ad hoc clinical autopsies and histopathological analyses could critically affect the validity of clinical translation in studies of human brain-immune interactions using neuroimaging. Advances in our understanding of brain-immune interactions are expected to translate into novel therapeutic avenues in a vast array of domains including cancer, autoimmune diseases or viral infections such as in acute and post-acute or Long COVID-19.

Association between Sirtuin 2 gene rs10410544 polymorphism and depression in Alzheimer's disease in two independent European samples.

Among the several genes associated with late-onset Alzheimer's disease (LOAD), recently, Sirtuin genes have roused a growing interest because of their involvement in metabolic homeostasis and in brain aging. Particularly SIRT2 gene has been associated with Alzheimer's disease (AD) as well as with mood disorders. The aim of this study is to investigate the possible associations between Sirtuin 2 gene (SIRT2) rs10410544 polymorphism and AD as well as depression in AD. In addition, we performed some exploratory analyses to investigate possible associations between the rs10410544 genotype and clinical features. We investigated these associations in two independent samples: the first one was composed of 275 Greek inhabitants and 117 patients; the second sample counted 181 Italian people and 43 patients. All patients were affected by LOAD. We failed to find any association between rs10410544 genotype and AD in the two samples. On the other hand, we found an association between the single nucleotide polymorphism (SNP) and depressive symptomatology (in the total sample p = 0.002), which was modulated by the tumor necrosis factor (TNF) values. Particularly, TT genotype seems to be protective versus depression. Finally, in the exploratory analyses, we found that the TT genotype was associated with earlier AD onset and a longer duration of the illness. In conclusion, we confirmed the association between SIRT2 gene and mood disturbances, although in AD patients. Further, we provided evidence that the TT genotype may be protective versus depressive symptoms, allowing an easier and thus earlier diagnosis of AD. This awareness may lead to a more detailed approach to these patients concerning diagnosis and therapy.

Pregabalin augmentation of antidepressants in older patients with comorbid depression and generalized anxiety disorder-an open-label study.

OBJECTIVE: The objective of this 12-week open-label study was to evaluate the efficacy, safety, and tolerability of pregabalin as an adjunctive treatment to antidepressants in older patients suffering from depression and comorbid generalized anxiety disorder (GAD). METHODS: The initial sample of this open-label study consisted of 94 older patients fulfilling criteria for depression with comorbid GAD who were treated with antidepressants. Twenty of them who had received antidepressant monotherapy for an adequate time and shown partial response to the antidepressant prescribed, in terms of either anxiety or depressive symptomatology, followed the next phase. During the 12-week study period, pregabalin was gradually added to the previously prescribed antidepressant, reaching 225 mg/day over 4 weeks. Depression and anxiety scores as well as side effects were monitored. Within groups, differences of depression and anxiety scores at baseline and during the following 12 weeks of treatment were estimated with repeated-measure analysis of variance. RESULTS: A statistical significant reduction in depression scores was observed after the 4th week of treatment (p < 0.01), which further improved between the 8th and 12th weeks (p < 0.01). Concerning overall anxiety scores, a statistically significant improvement was noted between the 2nd and 4th weeks (p < 0.01), which further continued throughout the 8th (p < 0.05) and 12th weeks (p < 0.05). CONCLUSIONS: The present study demonstrated a good therapeutic response to pregabalin in patients with depression comorbid with GAD after a 12-week treatment period. Both anxiety and depressive symptomatology significantly improved, and minimal side effects were observed.

Prevalence of psychiatric disorders among homeless people in Athens area: a cross-sectional study.

PURPOSE: Homelessness is a chronic social phenomenon in European and other Western cities. In the recent years, the number of homeless people in Greece, mainly in Athens, is also increasing. METHOD: The aim of this study was to explore the prevalence of psychiatric disorders among a sample of 254 homeless people, using the Mini International Neuropsychiatric Interview (M.I.N.I.). The sample was drawn from the existing shelters, soup kitchens, and the streets. RESULTS: The sample was predominantly male (74 %) with mean age 51 years, being in their majority homeless for over 25 months, 27 % of them living in the streets. The vast majority of the sample was single or separated with an education level <12 years. Current prevalence of psychiatric disorders was 56.7 % with 20.8 % comorbidity. For psychotic and mood disorders, current prevalence rates were 13 and 16 %, respectively. One year prevalence of alcohol and drug dependence was found to be low. Logistic regression analysis revealed that being older with higher number of months living in the streets and exposed to high frequency of adverse social events, increase the likelihood to become a psychiatric case. Finally, the vast majority of the identified psychiatric cases were lacking any current psychiatric care. CONCLUSIONS: The magnitude of the prevalence of psychiatric morbidity was more than three times higher than that of the general population in Athens. Implications for psychosocial care and the organization of a support network for the homeless people are discussed.
