    Cutaneous findings in children and adolescents with attention deficit and hyperactivity disorder
    (2020) Altunışık, Nihal; Ucuz, İlknur; Türkmen, Dursun
    Aim: Attention Deficit and Hyperactivity Disorder (ADHD) is the most frequently diagnosed psychiatric disorder in children. Only one study was found in literature which examined cutaneous findings in ADHD so far. The aim of the present study is to evaluate the cutaneous findings of children and adolescents diagnosed with ADHD and to compare the incidence of these findings with healthycontrols.Material and Methods: Forty-six patients diagnosed with ADHD according to The Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-V) criteria and 50 healthy controls with no ADHD symptoms that had similar characteristics to the patient group in terms of sociodemographic characteristics such as age and gender were included in the study. All the patients underwent whole body dermatological examination and pathological findings in the skin, hairy skin and nails in the patient and control group were recorded.Results: The most common finding in the patient group was found as onychophagy and/or periungual skin biting with a rate of 76.1%. In addition, statistically significant difference was found between the two groups in terms of xerosis, prurigo and allergy history.Conclusions: It is important to be careful in terms of cutaneous findings that may accompany ADHD in terms of both early treatment and also for preventing possible complications. In addition, determination of these findings will guide future studies in terms of identifying the common aetiology of ADHD and some cutaneous diseases.

    Evaluation of Inflammatory Markers in Childhood-onset Psychiatric Disorders by Using Artificial Intelligence Architectures
    (2020) Ucuz, İlknur; Özel Özcan, Özlem; Mete, Burak; Arı, Ali; Kayhan Tetik, Burcu; Yıldırım, Kübra
    Abstract: Objective: One of the mechanisms proposed in the etiology of psychiatric disorders is the immunological and inflammatory processes. The aim of this study was to evaluate the neutrophil/lymphocyte ratio (NLR), platelet/ lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR) and mean platelet volume (MPV) levels as an inflammatory marker in childhood-onset psychiatric disorders and to evaluate the inflammation parameters in the etiology. Methods: The hemogram data of 165 patients with early onset schizophrenia, bipolar disorder, depressive disorder and anorexia nervosa and 70 healthy children and adolescents were evaluated. In this study, artificial neural networks (ANN) are used for artificial intelligence-based computer aided system (CAS) design which can be able to help pediatric psychiatry specialists to diagnose easily and quickly. The data belonging to the patients were subjected to the normalization process in the designed system. Then, normalized data was entered to ANN and five outlets including four diseases and one test group were determined. The ANN model used has features of multilayer sensor network design. A three-tier cross validation method was used to test the success of the designed system. The three-tier cross-validation method is further divided into three parts. In each stage the first part was used for the test and the second and third parts was used for training. Results: The accuracy value of the model were calculated as 99%. Conclusion: These results show that the designed model gives robust and reliable results and can help the physicians in prediagnosis and differential diagnosis in clinical practice.

    Frequency of headache and related clinical factors in children and adolescents with tic disorders
    (2020) Çiçek, Ayla Uzun; Ucuz, İlknur; Bolayır, Ertugrul
    Aim: Only a few studies have investigated the comorbid headache in children with tic disorders (TD). In this study, thus, we aimed to examine the frequency and clinical correlates of comorbid headache in TD.Material and Methods: The sample consisted of 98 children and adolescents aged 6–16 years with a diagnosis of any tic disorder and 108 healthy children and adolescents matched for age, gender and sociocultural characteristics. All participants underwent a semi-structured psychiatric interview to establish a psychiatric diagnosis. The diagnosis of headache was made according to thethird edition of the International Classification of Headache Disorders criteria. Also, a specially prepared personal information sheet and Yale Global Tic Severity Scale were applied.Results: Children and adolescents with TD had a significantly higher frequency of headache compared to those in the control group (44.9% vs. 22.2%, p=0.001). The most common type of headache in both groups was migraine. We determined that the rate of diagnosis of chronic tic disorders, percentage of the presence of vocal tics, severity of tics, the proportion of patients takingpharmacotherapy for tics, and the rate of psychiatric comorbidity were significantly higher in patients with a headache than those without headache.Conclusion: The results of our study confirm studies showing suggesting a possible relationship between TD and headache, and supports the proposition that headache is a comorbidity of TD. However, further studies exploring the mechanisms of this relationship are required. It also would be advisable to screen children with TD in terms of headaches.

    Grafik Tablet Kullanılarak Makine Öğrenmesi Yardımı ile El Yazısından Cinsiyet Tespiti
    (2020) Arı, Berna; Arı, Ali; Ucuz, İlknur; Özdemir, Filiz; Şengür, Abdulkadir
    Öz: Günlük hayatın bir rutini olan el yazısı; ruh hali, kişilik özellikleri ve var olan bazı hastalıklar hakkında ipuçları vermektedir. Bunun yanında adli tıp, tıp ve arkeoloji gibi birçok disiplin el yazısını kendi alanlarına yönelik çalışmalarda sıkça kullanmaktadırlar. Örneğin adli tıp; bazı vakaların aydınlatılmasında el yazısından yaş aralığı ve hangi elin kullanıldığı gibi bilgilere ulaşabilmektedir. Bu çalışmada, el yazısından cinsiyet tespiti yapan bir sistem önerilmiştir. Önerilen sistem el yazısından, el yazısını karakterize edecek bir dizi öznitelik çıkarıp bu öznitelikleri makine öğrenmesi teknikleri kullanarak cinsiyete göre sınıflandırmıştır. El yazılarının kaydedildiği tabletle hem kalemin tablete temas halindeki durumunda hem de harfler ve kelimeler arası geçişte kalemin havada izlediği eğri hareketlerinden öznitelik çıkarılmıştır. Bu öznitelikler sırası ile kalem hızı, ivmesi, yazarken oluşan sarsıntı hareketleri, eğim açısı, yazıdaki kavislenmeler, kalemin havada kalma oranı, kalemin yaptığı basınç değeri ve kalemin yükseklik açısıdır. Sınıflandırıcı olarak da Karar Ağaçları (KA), Naive Bayes (NB), Destek Vektör Makineler (DVM) ve k-en Yakın Komşu (k-EYK) yaklaşımları kullanılmıştır. Deneysel çalışmalarda kullanılan veri setinde toplam 410 örnek mevcut olup, deneysel çalışmaların başarımları doğruluk kriteri ile değerlendirilmiştir. Elde edilen sonuçlara göre en iyi başarımın DVM ile elde edildiği ve doğruluk değerinin de %85,1 olduğu görülmüştür.

    (2021) Ucuz, İlknur; Uzun Çiçek, Ayla
    Abstract: Enuresis is a common pediatric condition and there are different treatment options. This study aimed to evaluate treatment options for enuresis in a sample of the childand adolescent psychiatry clinic. The data and treatment results of 98 patients (mean age: 10.38±2.15 years, range=6-16 years) diagnosed with enuresis between 1 May2015 and 1 October 2020 were retrospectively reviewed. We found that 57 of the patients had previously applied to the hospital for enuresis, and 14 of them have appliedto child and adolescent psychiatry, 10 of them to pediatric surgery, 20 of them to other branches of pediatrics, and 13 of them to the urology clinic. In previous hospitalapplications, behavioral treatment only had been applied to 40.4% of the patients, and pharmacotherapy had been applied in 59.6% of the patients. On the other hand,in the child and ado-lescent psychiatry clinic, 26.5% of the patients received behavioral treatment only, and 73.5% used drugs along with behavioral treatment, and themost frequently preferred drugs were imipramine (oftenest) and desmopressin. Also, the rates of psychiatric comorbidity in those who received medical treatment weresignificantly higher than those who treated behavioral treatment only. In conclusion, this study revealed that different clinical branches apply different treatment approachesto enuresis. In child and adolescent psychiatry, imipramine was the most commonly used agent in medical treatment, and this has been attributed to the high rate ofpsychiatric comorbidity
