Item The effects of gender and age on forensic personal identification from frontal sinus in a Turkish populationTatlisumak, E; Asirdizer, M; Bora, A; Hekimoglu, Y; Etli, Y; Gumus, O; Keskin, SObjectives: To define the dimensions of the frontal sinus in groups standardized for age and gender and to discuss the reasons and the effects of the variations. Methods: Frontal sinus measurements were obtained from paranasal CT scans of 180 males and 180 females in the Radiology Department of Dursun Odabas Medical Center of Yuzuncu Yil University, Van, which is located in Eastern Turkey, between February and March 2016. The width and height of sinuses were measured on a coronal plane, and the anteroposterior length was measured on an axial plane. Volumes were calculated using the Hospital Information Management Systems and Image Archiving and Management System program. The Statistical Package of the Social Science version 13 was used for statistical analyses. Results: We determined differences in the frontal sinus measurements of different age groups in a Turkish adult population. Frontal sinus dimensions were usually higher in females and lower in males after 40-49 years of age than their younger counterparts, but the measurements were lower in females and higher in males in 70 <= years of age group than 60-69 years of age. Left frontal sinus was dominant in young age groups but right frontal sinus was dominant in groups 40-49 years of age or older. Conclusion: We observed crossing of the measurements between the different age groups, which we could not find clear explanations. The results of such studies may affect forensic identification from frontal sinus measurements.Item Clinical significance of TT virus infection in children with chronic hepatitis BKasirga, E; Sanlidag, T; Akçali, S; Keskin, S; Aktas, E; Karakoç, Z; Helvaci, M; Sözen, G; Kuzu, MBackground: The pathogenic role of TT virus (TTV) is not clear in patients with chronic hepatitis B. The aims of the present study were to determine the frequency of TTV positivity in serum and saliva samples and the possible role of TTV in children with chronic hepatitis B. Methods: Sera and saliva from 29 healthy children and 25 children with chronic hepatitis B were tested for TTV-DNA by means of real-time polymerase chain reaction (PCR). Results: Fifty-two percent (13/25) of the serum samples and 32% (8/25) of the saliva samples were positive for TTV-DNA in children with chronic hepatitis B. In healthy non-transfused children, TTV-DNA was detected in 58% (17/29) of the serum samples and 41% (12/29) of the saliva samples. Six (46%) of 13 children with chronic hepatitis and 10 (59%) of 17 healthy children had TTV-DNA positivity both in serum and saliva samples. Two serum samples were negative for TTV-DNA while the saliva samples were positive for TTV-DNA in chronic hepatitis B and control groups. Mean age, sex, serum alanine aminotransferase levels, hepatitis B virus (HBV)-DNA values were similar in TTV-positive and -negative children with chronic hepatitis B. However, total histologic activity index (HAI), periportal necrosis and portal inflammation scores were significantly higher in children with HBV-DNA and TTV-DNA viremia (P = 0.013, P = 0.008, P = 0.015, respectively). Conclusions: Because total HAI, periportal necrosis and portal inflammation scores were higher in children with TTV coinfection, TTV infection may contribute to the progression of liver damage in children with chronic hepatitis B.Item Should the Western Aphasia Battery Be Translated into Turkish?Keklikoglu, HD; Selçuki, D; Keskin, SObjective: Aphasia tests are used to classify and diagnose aphasia. Aphasia tests, which can classify aphasia quantitatively, are needed for a standard classification of aphasia and to compare studies performed in different centers. The aim of this study was to assess the feasibility of the Turkish version of the Western Aphasia Battery (WAB), which classifies aphasia quantitatively, in Turkish speaking patients with aphasia. Methods: This study consisted of two stages. In the first stage, WAB was translated and adapted into Turkish. The Frenchay Aphasia Screening Test-Turkish (FAST) and Gulhane Aphasia Test (GAT) were applied to 20 aphasic patients in the second stage. Test results and lesion localizations were evaluated. Results: Two patients, who were found to be normal according to FAST, were evaluated to be aphasic according to the other tests. There was a high degree of correlation between the WAB-Turkish and the GAT scores. The results of the two tests regarding the lesion localization were also similar. The only difference was in the classification of aphasia. Conclusion: The difference in aphasia classification may be due to the personal interpretation of the test administrator during GAT aphasia classification or lack of a WAB standardization study. A standardization study for the Turkish version of WAB will be useful for studies on evaluation and classification of aphasia. (Archives of Neuropsychiatry 2010; 47: 40-6)Item The effect of altitude and climate on the suicide rates in TurkeyAsirdizer, M; Kartal, E; Etli, Y; Tatlisumak, E; Gumus, O; Hekimoglu, Y; Keskin, SSuicide is one of the most important public health problems. There was an association between suicide and several factors such as psychiatric diseases and psychological characteristics, somatic illness, cultural, socioeconomic, familial, occupational and individual risk factors. Also, high altitude and climatic factors including high temperature, cloudiness, more sunshine and low rainfalls were defined as some of these risk factors in the literature. In this study, we aimed to investigate correlation between suicide rates and altitudes of all cities in Turkey and between suicide rates and climatic factors including Rainfall Activity Index, Winter Mean Temperatures, Summer Mean Temperatures and Temperature Difference between January and July previously defined by several authors in the broad series in Turkey. In Turkey, 29865 suicidal deaths occurred in 10 years period between 2006 and 2015. Of them, 21020 (70.4%) were males and 8845 (29.6%) were females. In this study, we found that high altitude above 1500 m, winter median temperature lower than - 10 degrees C and hard temperature changes above 25 degrees C between winter and summer of settlements were important factors that affected on female suicide rates appropriate to knowledge which defined in previous studies. In conclusion, we suggested that the associations among suicide rates with altitudes and climate should be studied in wider series obtained from different countries for reaching more reliable results.Item The Possible Effects of Altitude and Climate on the Development of the Frontal Sinus in AdultsAsirdizer, M; Tatlisumak, E; Bora, A; Tarhan, S; Ovali, GY; Hekimoglu, Y; Kartal, E; Keskin, SClimatic and altitude features of living region may affect human body. Many changes in several tissues and organs and several health problems due to climatic and altitude effects were defined in the literature. However, there were limited number of studies which evaluated correlation between development of frontal sinus and climatic/altitude effect. In this study, widths, heights, AP lengths and volumes of frontal sinus were compared by Paranasal CT scans in populations living in Van which has colder climate and higher altitude and Manisa which has milder climate and lower altitude. It was found that widths, antero-posterior lengths and volumes of frontal sinus were higher in populations living in colder climate and higher altitude according to populations living in milder climate and lower altitude. Heights of frontal sinuses were on the contrary of this. These results were found appropriate to increasing of cephalic index in cold climate according to Allen's Rule. We suggest that larger population study should be made with peoples having the same or similar race and genetic structure in different climate and altitude regions and the proportional comparison of frontal sinus measurements with cephalic index should be considered in future studies.Item Enuresis nocturna and sleep qualityGozmen, S; Keskin, S; Akil, IEnuresis nocturna is a common problem. Numerous etiologic factors have been investigated, and various theories have been proposed. The objectives of our study were to establish the differences in the sleep quality of nocturnal enuretic patients from that of healthy voluntary subjects, and the changes after treatment with desmopressin acetate (DDAVP), among primary school children. The study comprised 19 children with primary nocturnal enuresis and 32 healthy children in the control group. Subjective assessment of sleep was determined with the Pittsburgh Sleep Quality Index (PSQI) questionnaire. PSQI scores for each patient and control subject were determined before the study was started and after a month time interval. The sleep quality of the nocturnal enuretic children was poor. We found lower scores after a month's treatment with DDAVP, and significant differences in two dimensions in the patient group: ` subjective sleep quality' and ` sleep disturbances'. When we asked the patients' group what caused the sleep disturbance, they replied ` the fear or the anxiety of bedwetting during sleep'. This anxiety or fear seemed to be a factor that probably affected their sleep quality. So, active treatment (medical or behavioral) should be started as soon as the child is ready to receive it or when the enuretic child wants to be dry when asleep.Item Effects of Chronic Boron Exposure on Semen ProfileKorkmaz, M; Yenigün, M; Bakirdere, S; Ataman, OY; Keskin, S; Müezzinoglu, T; Lekili, MThe possible changes in semen quality were studied in men living in a boron mining area. The subjects in the boron group had exposure to boron at an average level of 6.5 mg/day, as determined by urinary analysis. The results obtained by the boron group were compared to those obtained for the control group whose subjects were living in the same geographical area but away from the boron region; average exposure level was 1.4 mg/day for this group. The semen samples were analyzed according to the recommendations of the World Health Organization. Boron levels were established in the water samples obtained from various locations in the study region. In the boron mining fields where the subjects in the boron group live, water samples contained boron in the range of 1.4-6.5 mg/L, while the values were < 0.01 mg/L for the water samples obtained from the region where the subjects of the control group reside. No negative effects were found in the sperm samples obtained from the subjects of the boron group.Item COVID-19: booster(s) vs. hospitalization and Intensive Care Unit admissionToprak, OB; Akpolat, T; Uzun, O; Deniz, PP; Kokturk, N; Varol, A; Guzel, E; Ercelik, M; Gultekin, O; Guner, R; Turan, S; Bekta, SG; Coskun, N; Bakan, N; Yakar, MN; Kutsoylu, OE; Ergan, B; Baris, SA; Basyigit, I; Boyaci, H; Cetinkaya, F; Colak, H; Aykac, N; Ketencioglu, BB; Yüce, ZT; Isik, SA; Yilmaz, ES; Karaoglanoglu, S; Safgi, SB; Ozkan, G; Kose, N; Kizilirmak, D; Havlucu, Y; Nural, S; Kerget, F; Sunal, O; Yuksel, A; Dursun, ZB; Deveci, F; Kuluozturk, M; Ataoglu, O; Dursun, M; Keskin, S; Sezgin, ME; Sezgin, ENA; Eser, F; Akyildiz, L; Almaz, MS; Kayaaslan, B; Hasanoglu, I; Bayrak, M; Gümüs, A; Sagcan, G; Cuhadaroglu, C; Kucuk, H; Onyilmaz, T; Mete, B; Kilinc, O; Itil, BOOBJECTIVE: As the pandem-ic continues, different vaccine protocols have been implemented to maintain the protection of vaccines and to provide protection against new variants. The aim of this study was to as-sess hospitalized patients' vaccination status and document the efficacy of boosters.PATIENTS AND METHODS: The patients that were hospitalized due to COVID-19 were enrolled from 28 hospitals in Turkey for five months from September 2021. 5,331 confirmed COVID-19 pa-tients from collaborating centers were random-ly enrolled to understand/estimate the distri-bution of vaccination status in hospitalized pa-tients and to compare the efficacy of vaccina-tion/booster protocols.RESULTS: 2,779 men and 2,552 women of which 2,408 (45.2%) were admitted to Intensive Care Units participated in this study. It was found that the highest risk reduction for all age groups was found in groups that received 4 doses. Four doses of vaccination for every 3.7 people under 50 years of age, for every 5.7 people in the 50-64 age group, and for every 4.3 people over 65 years of age will prevent 1 patient from being admitted to intensive care. Regardless of the type of vaccine, it was found that the risk of ICU hospitalization decreased in those who were vaccinated compared to those who were not vaccinated. Regardless of the type of vaccine, the ICU risk was found to decrease 1.25-fold in those who received 1 or 2 doses of vaccine, 1.18-fold in those who received 3 dos-es, and 3.26-fold in those who received 4 doses.CONCLUSIONS: The results suggested that the addition of a fourth dose is more effective in preventing intensive unit care even in disad-vantaged.Item COVID-19: vaccination vs. hospitalizationUzun, O; Akpolat, T; Varol, A; Turan, S; Bektas, SG; Cetinkaya, PD; Dursun, M; Bakan, N; Ketencioglu, BB; Bayrak, M; Baris, SA; Guner, R; Gunal, O; Nural, S; Deniz, PP; Toprak, OB; Ozkan, G; Gumus, A; Kerget, F; Ercelik, M; Ataoglu, O; Yuksel, A; Ates, G; Kutsoylu, OE; Kose, N; Kizilirmak, D; Keskin, S; Gultekin, O; Coskun, N; Yilmaz, ES; Uslu, S; Basyigit, I; Ergan, B; Deveci, F; Yakar, MN; Zuhur, C; Sagcan, G; Yuce, ZT; Kuluozturk, M; Sezgin, ME; Sezgin, ENA; Havlucu, Y; Cuhadaroglu, C; Kilinc, O; Boyaci, H; Altunay, H; Akti, M; Dursun, ZB; Kalem, AK; Isik, SA; Akyildiz, L; Aykac, N; Almaz, MS; Kokturk, N; Itil, OObjective Vaccination is the most efficient way to control the coronavirus disease 2019 (COVID-19) pandemic, but vaccination rates remain below the target level in most countries. This multicenter study aimed to evaluate the vaccination status of hospitalized patients and compare two different booster vaccine protocols. Setting Inoculation in Turkey began in mid-January 2021. Sinovac was the only available vaccine until April 2021, when BioNTech was added. At the beginning of July 2021, the government offered a third booster dose to healthcare workers and people aged > 50 years who had received the two doses of Sinovac. Of the participants who received a booster, most chose BioNTech as the third dose. Methods We collected data from 25 hospitals in 16 cities. Patients hospitalized between August 1 and 10, 2021, were included and categorized into eight groups according to their vaccination status. Results We identified 1401 patients, of which 529 (37.7%) were admitted to intensive care units. Nearly half (47.8%) of the patients were not vaccinated, and those with two doses of Sinovac formed the second largest group (32.9%). Hospitalizations were lower in the group which received 2 doses of Sinovac and a booster dose of BioNTech than in the group which received 3 doses of Sinovac. Conclusion Effective vaccinations decreased COVID-19-related hospitalizations. The efficacy after two doses of Sinovac may decrease over time; however, it may be enhanced by adding a booster dose. Moreover, unvaccinated patients may be persuaded to undergo vaccination.
