Investigating the association between ınternet addiction, depression, social phobia, social anxiety and psychiatric disorders among secondary education students in Turkey

Introduction: The purpose of the study is to identify the prevalence of Internet addiction (IA) among students and evaluate the association of IA with depression, social phobia, social anxiety and psychiatric disorders. Materials and Methods: A total of 297 students aged 9-14 years and studying at a private school in Gölbaşı/Ankara province were included in the study. The study was conducted between November 2015 and May 2016. The student’s depression inventory; social phobia scale for student and adolescents; social anxiety scale for student-revised and strength and difficulties questionnaire were used as data collection tools. According to the Internet dependency scale, student were classified into 4 groups as non-addicted group, threshold group, risk group and addicted group. Results: According to the Internet dependency scale, the majority (258/86.9%) of the students were not Internet addicts. Twenty seven (9.1%) students were in the threshold group and 12 (4%) student were in the risk group. Compared with the depressed mood, the likelihood of having depression in the risk group was higher (p=0.001). The risk group and the threshold group had higher social phobia and social anxiety scores at a statistically significant level than the non-dependent group (p?0.05). Conclusion: Internet use is an indispensable element for the lives of generation-Z student. However Internet addiction, which is directly related to this condition, causes many psychological and social problems for student at an alarming level. These problems cannot be ignored and can be avoided by rational use of the internet. © 2022, Galenos Publishing House.

The Examination of Technological Device Usage and Sleep Habits among the Children Before and During the COVID-19 Pandemic

Objective:This study was conducted to examine the technological device usage states and sleep habits of 5-12 year-old children before and during the Coronavirus disease-2019 (COVID-19) pandemic.Materials and Methods:It is a descriptive study. This study was conducted with the parents of 488 children who were aged between 5-12 years old and studying in a kindergarten, 3 elementary schools and 3 secondary schools between March 2021 and June 2021. Data were collected by “Descriptive Information Form” and the “Children’s Sleep Habits Questionnaire (CSHQ)” in the study. Descriptive statistics and parametric tests were used to analyze the data.Results:In the study, a statistically significant difference was found in technological device usage and times of children before and during the COVID-19 pandemic period (p<0.05). It was determined that 100% of children had sleep problems clinically. A statistically significant difference was found between the mean scores of students from the CSHQ based on the education and income states of their parents (p<0.05). Additionally, a statistically significant difference was found between the mean CSHQ scores based on the duration of child’s daily technological device usage (p<0.05).Conclusion:Longer time spent with technological devices by 5-12 year old children during the COVID-19 pandemic was found to show a negative effect on the sleep habits of the children

Deaf athlete: is there any difference beyond the hearing loss?

Regular physical activity and sport is important for enhanced physical fitness and skill performance of deaf athletes. However there are few data in the literature about their medical considerations. In this study we aimed to determine the morphological findings and cardiac status of the deaf athletes and compare them with the normal ones. Thirty deaf and twenty-two normal male athletes without cardiovascular diseases participated in the study. Transthoracic echocardiography and exercise stress testing were performed. Tissue Doppler imaging (TDI)-derived myocardial performance index (MPI) was also evaluated. VO2 max and heart rate recovery were calculated after exercise stress testing. Total cholesterol, LDL and trigliseride levels were significantly increased in the deaf athletes, but they were still found to be in normal ranges according to age and risk factor profile (p< 0.05). End-diastolic diameter and left ventricular mass index were found to be significantly increased in the controls when compared with the deaf athletes (p< 0.001). Heart rate recovery at 1 minute did not show any difference in the deaf group when compared with the control group (p> 0.05). MPI calculated from TDI-derived variables was found to be 0.41±0.073 in the deaf group and 0.46±0.061 in the controls respectively and significantly decreased in the deaf (p < 0.05). Beyond having a hearing loss, the deaf athletes have many cardiac structural and functional differences from their normal counterparts. The factors that give rise to these differences have to be revealed by further research

Köprülerin Deprem Etkileri Altındaki Davranışları

Konferans Bildirisi-- İstanbul Teknik Üniversitesi, Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2017Conference Paper -- İstanbul Technical University, Theoretical and Applied Mechanical Turkish National Committee, 2017Depremlerde köprü, viyadük ve benzeri yapıların hasar görebildiği ve hatta yıkılabildiği bilinmekle birlikte; nedenleri henüz kesin olarak belirlenememiştir. Deprem etkisine maruz köprü türü yapıların davranışları araştırılırken, mevcut araştırmalarda genellikle sadece yatay etkilerin hesaba katıldığı görülmektedir. Hatta günümüze kadar süregelmiş önemli uluslararası şartnamelerde de yalnızca yatay etki hesaba katılmaktadır. Yalnızca yatay etkilerin hesaba katılmasında önemli nedenlerden bir tanesi, düşey yüklerin deprem esnasında meydana gelebilen olası çekme kuvvetlerine kıyasla küçük olması durumunda sistemin mekanizma haline gelmesi (oynak olması) ve sonuçta çözümün pratik olarak imkânsız hale gelmesidir. Bu durumda problem çözülememekte ve düşey etkiler hesaba katılamamaktadır. Mevcut çalışmada yapısal sistemlerin alışılagelmiş deprem analizlerinin yanı sıra düşey etkiler de hesaba katılmaktadır. Çalışmanın bu aşamasında yapısal elemanlar arasında göçme mekanizmaları belirlenebilmektedir. Konu ile ilgili çalışmaların yıllarca devam edeceği ön görülmekte ve devamında tüm yapısal sistemlerde (bina, baraj, köprü, viyadük vb.) düşey deplasman etkisinin göz önüne alınmasının kaçınılmaz olduğu sonucunun bulunmasının kuvvetle muhtemel olduğu düşünülmektedir. Bu durumda tüm analiz yöntemleri ve şartnameler gözden geçirilmelidir.It is known that bridges, viaducts and similar structures may be damaged and even destroyed under earthquake excitation; however, exact causes have not been determined yet. While the behavior of bridge-type structures subjected to earthquakes is being investigated; it is observed that, generally, only horizontal effects are included in the current studies. Furthermore, only the horizontal impact is taken into account by important prevailing international specifications/codes. One of the main reasons for inclusion of only horizontal effects in the calculation is the possibility for the system to become mechanism if the vertical loads are small compared to the probable tension forces during the earthquake, ultimately, causing the solution to become practically impossible. Because of this, the problem cannot be solved and the vertical effects cannot be taken into account. In the present study, besides the conventional earthquake analyses of structures with lateral forces, the vertical effects are also taken into account. At this stage of the study, the mechanisms of collapsing can be determined for the structural elements. It is anticipated that studies on the subject will continue for many years, and it is highly likely that the consideration of the vertical displacement effect would become inevitable for all types of structures (building, dam, bridge, viaduct etc.). In this case, all analysis methods and specifications should be reviewed

Effect of hesperetin on inflammatory and oxidative status in trinitrobenzene sulfonic acid-induced experimental colitis model

In our study, the effect of hesperetin on inflammatory and oxidative status in trinitrobenzene sulfonic acid (TNBS)-induced experimental colitis model was investigated through different methods. Eighteen Wistar albino male rats were divided in to three groups: Group I (Control, n = 8; 1 ml physiological saline), Group II (Colitis, n = 8; 1 ml TNBS), Group III (Hesperetin, n = 8; 1 ml TNBS and 100 mg/kg hesperetin). Macroscopic and microscopic scores were calculated to determine the damage to the colon at the end of the experiment. Serum tumor necrosis factor-? (TNF-?) and tissue interleukin-6 (IL-6) levels were determined using the ELISA method. Myeloperoxidase (MPO), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) levels were investigated spectrophotometrically. The TUNEL method was used for the detection of apoptotic cells in the colon tissue. Inducible nitric oxide synthase (iNOS) and nuclear factor-kappa-B (NF-??) expression in the colon were determined immunohistochemically. Hesperetin administration has shown to significantly reduce levels of MPO, MDA, and proinflammatory agents (TNF-?, IL-6, and NF-??). It has also been proven to inhibit mucosal apoptosis. This study indicates that hesperetin is protective against TNBS-induced colitis model via antiinflammatory, antioxidant and antiapoptotic effects. © 2018 by the C.M.B. Association.

Two Siblings with Isolated GH Deficiency Due to Loss−of−Function Mutation in the GHRHR Gene: Successful Treatment with Growth Hormone Despite Late Admission and Severe Growth Retardation

Patients with growth hormone releasing hormone receptor (GHRHR) mutations exhibit pronounced dwarfism and are phenotypically and biochemically indistinguishable from other forms of isolated growth hormone deficiency (IGHD). We presented here two siblings with clinical findings of IGHD due to a nonsense mutation in the GHRHR gene who reached their target height in spite of late GH treatment. Two female siblings were admitted to our clinic with severe short stature at the age of 13.8 (patient 1) and 14.8 years (patient 2). On admission, height in patient 1 was 107 cm (−8.6 SD) and 117 cm (−6.7 SD) in patient 2. Bone age was delayed in both patients (6 years and 9 years). Clinical and biochemical analyses revealed a diagnosis of complete IGHD (peak GH levels on stimulation test was 0.06 ng/mL in patient 1 and 0.16 ng/mL in patient 2). Patients were given recombinant human GH treatment. Genetic analysis of the GH and GHRHR genes revealed that both patientscarried the GHRHR gene mutation p.Glu72X (c.214 G>T) in exon 3 in homozygous (or hemizygous) state. After seven years of GH treatment, the patients reached a final height appropriate for their target height. Final height was 151 cm (−1.5 SD) in patient 1 and 153 cm (−1.2 SD) in patient 2. In conclusion, genetic analysis is indicated in IGHD patients with severe growth failure and a positive family history. In spite of the very late diagnosis in these two patients who presented with severe growth deficit due to homozygous loss−of−function mutations in GHRHR, their final heights reached the target height

Efficiency of Fluid Treatments with Different Sodium Concentration in Children with Type 1 Diabetic Ketoacidosis

Objective: The management of children with diabetic ketoacidosis (DKA) continues to be a controversial issue with regard to amount of intravenous fluid to be given, rate of delivery of fluid, and type of fluid to be used. We aimed to analyze the results obtained by administration of rehydration fluids of two different sodium (Na) concentrations (75 mEq/L vs. 100 mEq/L ) in the treatment of children with DKA

Case Report: Two Patients with Partial DiGeorge Syndrome Presenting with Attention Disorder and Learning Difficulties

DiGeorge syndrome (DGS) has classically been characterized by the triad of clinical features including congenital cardiac defects, immune deficiencies secondary to aplasia or hypoplasia of the thymus, and hypocalcaemia due to small or absent parathyroid glands. The phenotypic features of these patients are much more variable and extensive than previously ecognized. The acknowledgement of similarities and phenotypic overlap of DGS with other disorders associated with genetic defects in 22q11 has led to an expanded description of the phenotypic features of DGS including palatal/speech abnormalities, as well as cognitive, neurological and psychiatric disorders. Here, we report the cases of two DGS patients with dysmorphic facial features who were initially admitted to the Psychiatry Department for attention disorder and learning difficulties

Synchronous Occurrence of Papillary Carcinoma in the Thyroid Gland and Thyroglossal Duct in an Adolescent with Congenital Hypothyroidism

Thyroid carcinoma (TC) combined with congenital hypothyroidism is rare. The synchronous occurrence of these two conditions is even rarer. We describe a patient with congenital hypothyroidism in whom hyperthyroglobulinemia and nodules developed despite adequate replacement therapy. Papillary TC was detected at age 19 years. Postoperative diagnostic scintigraphy showed increased uptake in the thyroglossal duct region. Repetitive imaging of the thyroid gland can be useful in the early detection of TC in patients with congenital hypothyroidism. Moreover, this rare situation can be complicated by a synchronous thyroglossal duct carcinoma. Thyroglossal duct carcinoma can be detected if diagnostic scintigraphy is performed after total thyroidectomy
