Ottoman Masonry Bridges in Anatolia and the Balkans

Remains of the historical masonry bridges in Anatolia and the Balkans are dated back to the Roman (first half of the I. Millenium AD), to the Seldjukide (early centuries of the II. Millenium AD; basically in Anatolia), and to the Ottoman periods (13th to 19th centuries). Besides serving to transportation, bridges crossing watercourses have to be considered as important hydraulic structures. Built for military as well as economic purposes, more than one hundred Ottoman bridges (roughly two thirds in Anatolia and one third in the Balkans) served for several centuries; some of them being still in operation. They are silent witnesses of the hydraulic knowledge and solid construction technology of their times. In this inventory study, only Ottoman's masonry bridges in Anatolia and Balkans have been presented. Some of the Ottoman's masonry bridges had sunken in the reservoir of modern dams, some of them demolished during the construction of the new highways, and some of them are still in service

Testing Flood Estimation Methods On Ancient Closed Conduits

Beside a large number of ancient tunnels in long-distance water conveyance systems toancient cities in Turkiye, five peculiar closed conduits, through which almost the entire discharge of water courses were flowing, are investigated. These are the Cevlik (Seleucia Pieria) tunnel inHatay province; vaulted structures covering the river bed in Bergama (Pergamon), in Sultanhisar(Nysa), in Acarlar near Ephesus (all four are leading examples of largest closed conduits from Roman times in the world); and the Bezirgan tunnel east of Kalkan, being an interesting example of emissary conduits draining the floods of closed basins. The hydraulic capacities of these conduits are determined; their corresponding flood return periods are estimated by four synthetic flood hydrograph methods. However, it was not possible to deduce any generalized conclusion based on the comparison of these results

The socio-demographic, clinical and forensic medical investigation of suicide attempts over 18 years old presented to a training and research hospital’s emergency department: Izmir example

*Parlak, İsmail ( Aksaray, Yazar )Suicide and attempted suicide are among the causes of serious morbidity and mortality and are an important public health problem today. In this study, it was aimed to evaluate socio-demographic, clinical and forensic medical aspects of suicide attempters admitted to our hospital, to identify some risk factors. Thus, we emphasize the importance of suicide and drawing attention to taking measures to prevent suicides. The necessary permissions were obtained for the study. The records of 710 patients who applied to the Emergency Department of Izmir Bozyaka Training and Research Hospital between 01 January 2014 and 31 December 2015 were retrospectively reviewed. 54.9% of the patients were female and 45.1% were male. Their ages ranged from 18 to 87 years and the mean age was 32.13 ± 11.52 years. It was determined that they preferred to drink drugs most frequently (n = 665, 93.7%) and then die with firearm (n = 30, 4.2%). Four (0.6%) cases died after all interventions. There is much scientific research on suicide attempts. However, there is insufficient research on how to approach suicidal cases when emergency department workers encounter suicide attempts. In order to prevent suicide attempts and deaths which are a serious public health problem, we think that risk factors should be determined, and protective measures should be taken

Sex differences of migraine: Results of a nationwide home-based study in Turkey

Introduction: The prevalence of migraine was found to be more than three-fold higher in women as compared with men, and in addition to differences in prevalence rates, the characteristics and associated features might also differ between the sexes. The aim of this study was to compare sex-specific features of migraine and demographic parameters in a nationwide population-based study in Turkey. Methods: Among 5323 subjects, a total of 871 patients who were diagnosed as having definite migraine according to the diagnostic criteria of the International Classification of Headache Disorders-III (ICHD-III) were included in our study. The demographic characteristics, associated features, and triggers of migraine were examined with regard to sex. Results: The study group comprised 640 women (73.5%) and 231 men (26.5%), with a female to male ratio of 2.8:1. Attack duration, mean migraine disability assessment scores (MIDAS), frequencies of nausea, vomiting, osmophobia, vertigo/dizziness, and allodynia were found significantly different between women and men. When we compared these parameters between men and postmenopausal women, all these parameters were still significant except nausea. Odor was statistically more frequent as a reported trigger in women, whereas excessive sleep was a statistically more frequent triggering factor in men. The rates of depression and allergy were significantly higher in women when compared with men. Conclusion: Longer attack duration, higher MIDAS scores, and the frequencies of nausea, vomiting, osmophobia, vertigo/dizziness, and allodynia were more significant in women and this variance in sex persisted after menopause. Also, some trigger factors and co-morbidities differed between the sexes. These findings might result from complex genetic factors besides sociocultural influences, biologic, and sociocultural roles. Future studies should continue to explore biologic and genetic factors with respect to sex in migraine

Applicability of pressure retarded osmosis power generation technology in Istanbul

In this study, the applicability of pressure retarded osmosis power generation was investigated in order to meet the electricity demand in Turkey. Pressure retarded osmosis (PRO) is a method that converting salinity gradients to power using a semi-permeable membrane against an applied pressure and PRO is one of the promising candidates to reduce fossil fuel dependency. In PRO, water is transported from a low concentrated feed solution to a high-concentrated draw solution. According to the literature findings, in order to produce 1MW of electricity 1m3/s fresh water flow is needed. Turkey is surrounded on three sides by water and has a big potential to develop this technology. Riva River is investigated in the scope this study. Currently Turkey’s total installed power capacity reached 85.200 MW at the end of 2017.Calculations of PRO power generation reveals that it is possible to generate 25,45 MW, If using 5% of total river flow

One-year prevalence and the impact of migraine and tension-type headache in Turkey: a nationwide home-based study in adults

Several studies have shown that the prevalence of migraine and tension-type headache (TTH) varied between different geographical regions. Therefore, there is a need of a nationwide prevalence study for headache in our country, located between Asia and Europe. This nationwide study was designed to estimate the 1-year prevalence of migraine and TTH and analyse the clinical features, the impact as well as the demographic and socio-economic characteristics of the participant households in Turkey. We planned to investigate 6,000 representative households in 21 cities of Turkey; and a total of 5,323 households (response rate of 89%) aged between 18 and 65 years were examined for headache by 33 trained physicians at home on the basis of the diagnostic criteria of the second edition of the International Classification of Headache Disorders (ICHD-II). The electronically registered questionnaire was based on the headache features, the associated symptoms, demographic and socio-economic situation and history. Of 5,323 participants (48.8% women; mean age 35.9 ± 12 years) 44.6% reported recurrent headaches during the last 1 year and 871 were diagnosed with migraine at a prevalence rate of 16.4% (8.5% in men and 24.6% in women), whereas only 270 were diagnosed with TTH at a prevalence rate of 5.1% (5.7% in men and 4.5% in women). The 1-year prevalence of probable migraine was 12.4% and probable TTH was 9.5% additionally. The rate of migraine with aura among migraineurs was 21.5%. The prevalence of migraine was highest among 35–40-year-old women while there were no differences in age groups among men and in TTH overall. More than 2/3 of migraineurs had ever consulted a physician whereas only 1/3 of patients with TTH had ever consulted a physician. For women, the migraine prevalence was higher among the ones with a lower income, while among men, it did not show any change by income. Migraine prevalence was lower in those with a lower educational status compared to those with a high educational status. Chronic daily headache was present in 3.3% and the prevalence of medication overuse headache was 2.1% in our population. There was an important impact of migraine with a monthly frequency of 5.9 ± 6, and an attack duration of 35.1 ± 72 h, but only 4.9% were on prophylactic treatment. The one-year prevalence of migraine estimated as 16.4% was similar or even higher than world-wide reported migraine prevalence figures and identical to a previous nation-wide study conducted in 1998, whereas the TTH prevalence was much lower using the same methodology with the ICHD-II criteria

A comparative ID migraine screener study in ophthalmology, ENT and neurology out-patient clinics

Migraine is more likely to be misdiagnosed in patients with comorbid diseases. Not only primary care physicians, but also specialists might misdiagnose it due to the lack of diagnostic criteria awareness. The ID migraine test is a reliable screening instrument that may facilitate and accelerate migraine recognition. This study aimed to compare the prevalence and characteristics of migraine in a large sample of patients admitted to clinics of ophthalmology (OC), ear, nose and throat diseases (ENTC) and neurology (NC), as well as to validate the use of the ID migraine test in OC and ENTC settings. This was a multicentre (11 cites) study of out-patients admitting either to NC, ENTC or OC of the study sites during five consecutive working days within 1 week. From each of the clinics, 100 patients were planned to be recruited. All recruited patients were interviewed and those having a headache complaint received an ID migraine test and were examined for headache diagnosis by a neurologist, blinded to the ID migraine test result. A total of 2625 subjects were recruited. Only 1.3% of OC patients and 5.4% of ENTC patients have been admitted with a primary complaint of headache, whereas the percentage of NC patients suffering from headache was 37.6%. Whereas 138 patients (19.3%) in OC, 154 (17.3%) in ENTC and 347 (34%) in NC were found to be ID migraine test positive, 149 patients (20.8%) in OC, 142 (16%) in ENTC and 338 (33.1%) in NC were diagnosed with migraine. The sensitivity, specificity, and positive and negative predictive ratios of the ID migraine test were found to be similar in all clinics. An important fraction of the patients admitted to NC, as well as to OC and ENTC, for headache and/or other complaints were found out to have migraine by means of a simple screening test. This study validated the ID migraine test as a sensitive and specific tool in OC and ENTC, encouraging its use as a screening instrument.Pfizer-Türkiy

Medication Overuse Headache: The Reason of Headache That Common and Preventable

Medication overuse headache (MOH) is well-defined clinically and is one of the common reasons of chronic daily headache, but its pathophysiology has not been elucidated yet. MOH has varying clinical features in regard to regional, psychosocial, medical and economic factors. Even though, the studies have shown that many factors may play a role, MOH is likely to occur in patients who are prone to primary headaches. Mainstay of the treatment is to withdraw the excessively used analgesic drugs. The primary prevention with education of the patients as well as early diagnosis and treatment of MOH will reduce its increasing financial burden on both patients and countries. Meticulous and multifactorial evaluation of the disease besides the diagnosis and treatment of the comorbid diseases will reduce the risk of recurrences
