Published: May 2018

Brucella spp. prosthetic joint infections are infrequently reported in the literature, particularly in returning travellers, and optimal treatment is unknown.METHOD:We describe a prosthetic joint infection (PJI) caused by Brucella melitensis in a traveller returning to the UK from Thailand, which we believe to be the first detailed report of brucellosis in a traveller returning from this area. The 23 patients with Brucella-related PJI reported in the literature are summarised, together with our case.RESULTS:The diagnosis of Brucella-related PJI is difficult to make; only 30% of blood cultures and 75% of joint aspiration cultures were positive in the reported cases. Culture of intraoperative samples provides the best diagnostic yield. In the absence of radiological evidence of joint loosening, combination antimicrobial therapy alone may be appropriate treatment in the first instance; this was successful in 6/7 [86%] of patients, though small numbers of patients and the likelihood of reporting bias warrant caution in drawing any firm conclusions about optimal treatment. Aerosolisation of synovial fluid during joint aspiration procedures and nosocomial infection has been described.CONCLUSIONS:Brucella-related PJI should be considered in the differential of travellers returning from endemic areas with PJI, including Thailand. Personal protective equipment including fit tested filtering face piece-3 (FFP3) mask or equivalent is recommended for personnel carrying out joint aspiration when brucellosis is suspected. Travellers can reduce the risk of brucellosis by avoiding unpasteurised dairy products and animal contact (particularly on farms and abattoirs) in endemic areas and should be counselled regarding these risks as part of their pre-travel assessment.

Uremic lung is different entity then oedema present in cardiovascular diseases or in adult respiratory distress syndrome as well. This state is one of the possible complications in patients with chronic renal failure (CRF) receiving regular hemodialysis (HD). There are several studies suggesting that in these patients in 30-40% cases pulmonary hypertension was developed. It is known that patients with primary pulmonary hypertension have peripheral airway obstruction The data also showed that primary as well secondary pulmonary hypertension are more often developed in females; even real reason is still unknown. The aim of the study was to estimate the ventilator functionimprovement in patients with CRF receiving regular HD related to sex differences. The study population consisted in 39 patients with CRF, with no cardiac and pulmonary diseases. These patients were treated by regular hemodialysis using bicarbonate or acetate mode, respectively. They were divided into two groups according to the sex. Spirometry parameters before and after onset of hemodialysis were recorded. The results were analyzed using Student t-test and presented as mean +/-SD. All p values <0,05 were considered significant. The result showed that ventilatory function in male patients is significantly improved, especially VC and FEV1, whereas in female patientsimprovement had not statistical significance. It can be concluded that one of the possible reasons for slight improvement of ventilatorfunction in female patients is pulmonary hypertension.

The aim of the study was to define the distribution of p53, bcl-2 and Ki-67 proteins in the inflammatory-regenerative and dysplastic lesionsof the colon mucosa. The relationship between the presentation of p53, bcl-2 and Ki-67 proteins and the intensity of the inflammatory-regenerative and dysplastic lesions in the colon flat mucosa was investigated as well. Biopsy specimens from 270 patients were examined: 74 were classified as inflammatory-regenerative and 196 as dysplastic lesions (108 mild, 58 moderate, and 30 severe dysplasia). The expression of all three proteins was assessed on the basis of location, quantity, and intensity of immunostaining, by counting antigen positive cells, in comparison with normal mucosa and adenocarcinoma. p53 protein appears only in sporadic cases (6.6%) of severe dysplasia. Bcl-2 expression appears significantly (p<0.005) more often in cases of mild dysplasia (61.1%) compared to inflammatory-regenerative mucosa (14.8%). In cases of mild dysplasia, bcl-2 positive cells were spreading from the lower third to the middle third of the crypts. Bcl-2 expression was maintained through the stadiums of moderate and severe dysplasia (75.8%), where antigen positive cells were found all along the crypts. A significant increase (p<0.005) in the expression of nuclear protein Ki-67 was noticed in the stadiums of moderate (labelling index =26.3) compared to mild dysplasia (labelling index=16.7), and severe (labelling index=36.7) compared to moderate dysplasia, where the zone of cellular proliferation was widen along the whole crypt length. In the process of the development of epithelial dysplasia in the flat mucosa of colon a degree of the gene p53 alteration is low and appears only in sporadic cases of severe dysplasia. Mutation of the bcl-2 gene is involved in the genesis of the lesion but not in its progression to carcinoma. Increased expressionof Ki-67 protein speaks in favour of an increased cellular proliferation which, together with the above mentioned mechanisms, is involved in the process of occurrence and progression of epithelial dysplasia in the flat mucosa of colon.

Authors: Kreso Amir , Arslanagić Amila 
Published: May 2018

The study was designed with the main intent to assess and explain the differences between athlete’s heart syndrome and the heart of healthy non-athletes, and to distinguish between physiological and pathological heart condition. Prolonged athletic training causes changes in heart that are termed “athlete’s heart syndrome’! Athlete’s heart diagnosis and related issues are a great challenge due to complementary morphological, functional and electro-physiological changes that may indicate both physiological and pathological condition. The study included 150 subjects, of those 100 were active athletes and 50 were in control group. The study protocol included one clinical examination, one electrocardiogram and one echocardiograph for each subject. Average age was 20,51±8,51 in the athletes and 21,48±2,53 in control group. Significantly higher average left ventricle (LV) mass (401,23g vs. 143,23g) and LV mass index (196,05g/m2 vs. 83,98g/m2) was found in the athletes (p<0,05). The study showed increased mass and wall thickness with usual inner dimensions of athlete’s heart. Systolic and diastolic function of athlete’s heart is normal. Athlete’s heart with these features is a healthy heart.
Szempontok a városi kormányzási elméletekhez Budapest, Bécs, Prága és Varsó közigazgatási helyzetének összehasonlítása alapján
Authors: Hilbert Bálint 
Published: May 2018

A városi kormányzás (urban governance) szemléletmódja az utóbbi évtizedekben népszerű kutatási témává nőtte ki magát. A kutatások középpontjában elsősorban az állami és privát szereplők együttműködése, valamint a városrégiós kormányzás kérdéskörei állnak, arról azonban lényegesen kevesebb szó esik, hogy a városok milyen tágabb jogi-közigazgatási környezetbe ágyazódnak, illetve hogy ennek milyen hatása lehet a városi kormányzás egyéb aspektusaira. Az urban governance elméleteinek nagy része a nyugati (főként angolszász) nagyvárosokban tapasztaltakra épül, más térségek nagyvárosainak kormányzási jellemzőire ugyanakkor csekély a rálátásunk.
E kutatási deficitre reagálva a tanulmány négy közép-európai főváros – Budapest, Bécs, Prága és Varsó – állami közigazgatási struktúrába való beépülését, belső kormányzási viszonyait (a főváros-kerület viszonyrendszert), valamint ezek 1990 óta történt változásait mutatja be. A több tekintetben hasonló fővárosok vizsgált közigazgatási jellemzői jelentős mértékben eltérnek egymástól. Budapest szinte minden vizsgálati szempont alapján élesen elkülönül a többi várostól, míg Bécs, Prága és Varsó közigazgatása több tekintetben hasonlít egymásra. A lengyel főváros Budapesthez hasonló kormányzási rendszerének közelmúltban történt radikális megváltoztatása figyelemre méltó fejlemény lehet a magyar fővárosra nézve. A négy város összehasonlítása nemcsak arra mutatott rá, hogy a városi kormányzási vizsgálatoknak számba kell venniük a városok közigazgatási környezetét, hanem egyúttal arra is, hogy Budapest kormányzása további kutatásokat igényel.

Published: May 2018

<p><em>A 48-year-old male was admitted to the emergency department because of intermittent chest pain of 2 days duration. At the time of examination, he was pain-free. An electrocardiogram (ECG) showed biphasic T waves in leads V2 to V6. Troponin-I level was negative. During his transfer to the cardiac catheterization laboratory, he had a short episode of chest pain. His ECG was normal. Despite the unusual extension of biphasic T waves to the lateral precordial leads, the condition was recognized as Wellens’ syndrome, which typically associates biphasic or deep symmetric T wave inversion in leads V2 and V3 during pain-free periods with a critical stenosis in the proximal left anterior descending artery. The syndrome is uncommon to medical practice but should be recognized immediately in the emergency department because it represents a pre-infarction stage and carries a high risk of mortality. </em><em></em></p>

Dear Reader, According to Plato (Phaedo), "it seems to me that if there is something beautiful on the margins of the beautiful itself, it will not be beautiful for any other reason, except it partakes of that beauty." Thus, the beauty of scientific production is complemented in the integrity and integrality of scientific publication. The identity of the production is reflected in the image of the publication. However, the publication itself is endowed with its own identity and reflects in its image, in the context of the epistemological, theoretical, morphological, technological and metric density of the approaches, manifested in the specific aesthetics of a scientific text. Thus, the text must be endowed with scientific and technical density, but express an aesthetic that embodies the beauty of the world of science.

Mobbing kavramı,
iş hayatında etkileri iş yaşamının dışına taşan önemli bir sorun kaynağıdır.
Kamu ve özel birçok örgütü derinden etkileyen mobbing sorunsalı Türkiye’de özel
ve kamu üniversitelerinde görev yapan personel tarafından nasıl algılandığı bu
çalışmanın öncelikli amacını oluşturmaktadır. Üniversite çalışanlarının mobbing
konusundaki düşünceleri diğer kamu ve özel örgütlere göre daha demokratik ve
özgür düşüncenin ön planda olduğu bu kurumların mobbing olgusu karşısındaki
konumunun incelenmesini gerekli kılmaktadır. Bu kapsamda hazırlanan çalışmada
Türkiye genelinde özel ve kamu üniversitelerinde çalışan akademik personele
tesadüfi olarak e-mail olarak gönderilen anketlerden sağlıklı bir şekilde geri
dönen 442 adet anket üzerinden Spss programından faydalanılarak akademik
personelin mobbing konusunda genel ve kurumsal algılarını saptamaya yönelik Ki

TÜRKİYE’DE PETROL FİYATLARI VE CARİ AÇIK ARASINDAKİ SİMETRİK VE ASİMETRİK NEDENSELLİK İLİŞKİLERİNİN ANALİZİ
Authors: KIRCA Mustafa , KARAGÖL Veysel 
Published: May 2018

Gelişmekte olan ve özellikle de enerjide dışa
bağımlılığı yüksek olan ülkelerde petrol fiyatları, cari işlemler dengesinin
önemli belirleyicilerindendir. Türkiye ekonomisinin dinamikleri incelendiğinde
enerjide dışa bağımlılığın yüksek olduğu ve petrolün hem üretim hem de tüketim
girdisi olarak yoğun bir biçimde kullanıldığı görülmektedir. Bu nedenle, artan
petrol fiyatlarının Türkiye ekonomisinin cari açığını arttıracağı
düşünülmektedir. Bu çalışmada Türkiye’de petrol fiyatları ile cari açık
arasındaki nedensellik ilişkilerinin incelenmesi amaçlanmaktadır. Bu amaç
doğrultusunda 1998Q1 ve 2016Q3 dönemine ait petrol fiyatları ve Türkiye’nin
cari açık değerlerine ait veriler, Hacker ve Hatemi-J (2006) simetrik
nedensellik testi ve Hatemi-J (2012) asimetrik nedensellik testi kullanılarak
analiz edilmiştir. Hacker ve Hatemi-J (2006) simetrik nedensellik testi
bulgularına göre petrol fiyatlarından cari açığa doğru tek yönlü nedensellik
vardır. Hatemi-J (2012) tarafından geliştirilen asimetrik nedensellik testi sonuçlarına
göre ise negatif petrol fiyatları şoklarından pozitif cari açık şoklarına doğru
nedensellik ilişkisinin olduğu tespit edilmiştir. Ayrıca, Hatemi-J (2011)
tarafından geliştirilen asimetrik etki-tepki fonksiyonları kullanılarak
şokların etkileme yönleri tespit edilmiştir.
