Neuro-Behçet: a clinical exercise

Behçet disease is a recurrent systemic vasculitis of unknown etiology, that involves vessels of nearly all sizes and types. Because of this, disease manifestations can occur at many sites throughout the body. Central nervous system (CNS) involvement may be parenchymal or nonparenchymal and has a global prevalence that ranges from 3% to 10%. Main signs of CNS involvement are pyramidal and those resulting from brain stem lesions. Aseptic meningitis, mental changes, sphincter disturbances, pseudobulbar syndrome, and deep sensory abnormalities may be seen. Analysis of cerebrospinal fluid, computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT) and brain angiography offer assistance in the diagnosis. The course of disease can be primary progressive, secondary progressive or have a relapsing-remitting profile. Boluses of methylprednisolone for three days followed by cyclophosphamide are the treatment of choice. This papers discusses these aspects of neuro-Behcet on the basis of complex clinical cas

Sebomic identification of sex- and ethnicity-specific variations in residual skin surface components (RSSC) for bio-monitoring or forensic applications

Background: “Residual skin surface components” (RSSC) is the collective term used for the superficial layer of sebum, residue of sweat, small quantities of intercellular lipids and components of natural moisturising factor present on the skin surface. Potential applications of RSSC include use as a sampling matrix for identifying biomarkers of disease, environmental exposure monitoring, and forensics (retrospective identification of exposure to toxic chemicals). However, it is essential to first define the composition of “normal” RSSC. Therefore, the aim of the current study was to characterise RSSC to determine commonalities and differences in RSSC composition in relation to sex and ethnicity. Methods: Samples of RSSC were acquired from volunteers using a previously validated method and analysed by high-pressure liquid chromatography–atmospheric pressure chemical ionisation–mass spectrometry (HPLC-APCI-MS). The resulting data underwent sebomic analysis. Results: The composition and abundance of RSSC components varied according to sex and ethnicity. The normalised abundance of free fatty acids, wax esters, diglycerides and triglycerides was significantly higher in males than females. Ethnicity-specific differences were observed in free fatty acids and a diglyceride. Conclusions: The HPLC-APCI-MS method developed in this study was successfully used to analyse the normal composition of RSSC. Compositional differences in the RSSC can be attributed to sex and ethnicity and may reflect underlying factors such as diet, hormonal levels and enzyme expression.Peer reviewedFinal Published versio

The glial growth factors deficiency and synaptic destabilization hypothesis of schizophrenia

BACKGROUND: A systems approach to understanding the etiology of schizophrenia requires a theory which is able to integrate genetic as well as neurodevelopmental factors. PRESENTATION OF THE HYPOTHESIS: Based on a co-localization of loci approach and a large amount of circumstantial evidence, we here propose that a functional deficiency of glial growth factors and of growth factors produced by glial cells are among the distal causes in the genotype-to-phenotype chain leading to the development of schizophrenia. These factors include neuregulin, insulin-like growth factor I, insulin, epidermal growth factor, neurotrophic growth factors, erbB receptors, phosphatidylinositol-3 kinase, growth arrest specific genes, neuritin, tumor necrosis factor alpha, glutamate, NMDA and cholinergic receptors. A genetically and epigenetically determined low baseline of glial growth factor signaling and synaptic strength is expected to increase the vulnerability for additional reductions (e.g., by viruses such as HHV-6 and JC virus infecting glial cells). This should lead to a weakening of the positive feedback loop between the presynaptic neuron and its targets, and below a certain threshold to synaptic destabilization and schizophrenia. TESTING THE HYPOTHESIS: Supported by informed conjectures and empirical facts, the hypothesis makes an attractive case for a large number of further investigations. IMPLICATIONS OF THE HYPOTHESIS: The hypothesis suggests glial cells as the locus of the genes-environment interactions in schizophrenia, with glial asthenia as an important factor for the genetic liability to the disorder, and an increase of prolactin and/or insulin as possible working mechanisms of traditional and atypical neuroleptic treatments

Addiction profile in probation practices in Turkey: 5-year data analysis

Ahmet Bülent Yazici,1 Esra Yazici,2 Neslihan Akkisi Kumsar,1 Atila Erol2 1Department of Psychiatry, Sakarya University Training and Research Hospital, 2Department of Psychiatry, Sakarya University Faculty of Medicine, Sakarya, Turkey Introduction: While drug addiction is a global problem, it is important for every region to know the general features of its own addicts in order to develop effective treatment programs. This study presents sociodemographic data of the individuals diagnosed with drug addiction.Methods: In this study, data of the patients between the years of 2009 and 2014 were retrospectively analyzed. The patients were assessed at psychiatry polyclinics according to probation practices of drug abuse. The study involved 513 patients in whom drug positivity was detected in urine analysis at least once and whose diagnoses were confirmed with a clinical interview.Results: According to this study, a majority of the addicts were detected in 2013. Males made up 98.2% of the sample population, their average age was 32.12±10.21 years, and minimum and maximum ages for the first drug use were 7 years and 45 years, respectively. Marijuana use was found in 90.8% of the patients, 90% of them were living with their families, and 59.6% of them held a regular job. Treatment response was related with age of first use of drugs, duration of use drugs, and prior treatment anamnesis of the patients.Conclusion: In this study, it was determined that the drug which was most frequently was used marijuana. The risk of drug addiction can affect any individual in society, regardless of their education, occupation, or social support levels. Alternative treatment models, especially for chronic and long-term users, should be researched. Keywords: addiction, crime, cannabis, substance us

Atrial natriuretic peptide and posterior pituitary neurohormone changes in patients with acute schizophrenia

Derya Guzel,1 Ahmet Bulent Yazici,2 Tugba Mutu Pek,2 Songul Doganay,1 Alime Burcin Saykan Simsek,2 Kadir Saglam,1 Caglar Turan,2 Esra Yazici2 1Department of Physiology, School of Medicine, Sakarya University, Sakarya, Turkey; 2Department of Psychiatry, School of Medicine, Sakarya University, Sakarya, Turkey Objectives: Interactions between neuropeptides and psychiatric disorders have been investigated for many years. The aim of this study was to evaluate oxytocin (OXT), arginine-vasopressin (AVP), and atrial natriuretic peptide (ANP) and assess their interactions with each other, as well as investigate these changes with the manifestations of schizophrenia. Participants and methods: Thirty-four individuals having acute schizophrenia and 24 healthy individuals as the control group were included in the study. Positive and Negative Syndrome Scales, Global Assessment of Functionality score, and Clinical Global Impression (CGI) scores were measured. Serum hormone levels were analyzed using enzyme-linked immunosorbent assay and were compared with the clinical findings. Results: OXT levels were significantly lower and AVP levels were significantly higher in patients having acute schizophrenia than the control group. OXT was negatively correlated with Positive and Negative Syndrome Scales positive score and CGI score, while it was positively correlated with Global Assessment of Functionality score. AVP was negatively correlated with CGI score. ANP levels of the patients having schizophrenia were lower than the control group; however, there was no significant correlation with clinical findings. Conclusion: The obtained data indicate that the AVP level was higher, but OXT and ANP levels were lower in the patients having acute schizophrenia. Specifically OXT is related with reduced disease severity and increased functionality. Keywords: schizophrenia, oxytocin, PANS, GAF, CGI, AV
