Acute Facial Paralysis Due to EBV Infection

Ebstein Barr virüs (EBV) Herpes-viridae ailesinin bir üyesidir. EBV enfeksiyonu seyrinde üst solunum yolu enfeksiyonu bulguları ile birlikte asemptomatik karaciğer enzimlerinde yükselme sıklıkla izlenmekle birlikte akut fasiyal paralizi oldukça nadir görülmektedir. Burada sekiz yaşında EBV enfeksiyonuna bağlı akut fasiyal paralizi olgusu sunulmuştur. Semptomatik tedavi ile birlikte hasta kortikosteroid ve antiviral tedavi ile sekelsiz iyileşmiş ve herhangi bir komplikasyon gelişmemiştir. Hekimler EBV’ye bağlı gelişen enfeksiyöz mononükleoz seyri sırasında üst solunum yolu enfeksiyonları dışında fasiyal paralizi gibi nörolojik komplikasyonların da gelişebileceğini ve hastaların yakından takip edilmesi gerektiğini akılda bulundurmalıdır.Ebstein Barr virus (EBV) is a member of Herpes-viridae. Altough elevations of liver enzymes and upper respiratory tract infection findings is commonly seen during the EBV infection, acute facial paralysis is rare complication. Here, we report acute facial paralysis associated with EBV infection in an eight years old girl. With symptomatic treatment, the patient recovered without cure with corticosteroids and antiviral therapy and no complications developed. Physicians should keep in mind that neurological complications, such as facial paralysis, other than upper respiratory tract infections, may develop during infectious mononucleosis due to EBV and that patients should be followed closely

Assessment of heavy metal contamination in natural waters of Dereli, Giresun: an area containing mineral deposits in northeastern Turkey

The concentration of heavy metals in the natural waters of the area surrounding Dereli (Giresun), a mineralized area, was determined. In addition, the physicochemical parameters (such as pH, Eh, and HCO3-) influencing the concentration of dissolved metals in waters were evaluated. Samples were collected from stream, spring, and main river waters, some of which are used by local residents for drinking, fish farming, and animal husbandry. The present data indicate that the water-rock interaction is the main process controlling the chemical composition of waters in the area. The waters are predominantly CaMgHCO3-type waters with alkaline pH values. Heavy metal concentrations (Pb, Zn, Cu, Fe, Mn, U, Cd, As, Hg, Sb, Ni, Co, and Ba) in waters were generally low. Relatively high values of certain metals were determined in waters of the Kotana and Kurtulmus sites of Dereli. The levels of Pb in the river, stream, and spring water samples in these sites were somewhat higher than the Pb values reported in the literature for natural waters. However, these values only slightly exceeded the Pb water limit values proposed by the USEPA and the WHO. In addition, the concentrations of other heavy metals, except Pb, were fairly similar to those of other natural waters and these values were also under the drinking water limits set by the WHO and the USEPA. This study shows that waters in the area of Dereli were not significantly affected by mineralization. This is most likely caused by the bicarbonate-rich waters affecting the dissolved metal concentrations

Major, trace and rare earth element (REE) characteristics of tuffs in the Yenice-Saraycik area (Demirci, Manisa), Western Anatolia, Turkey

Geochemical investigation was carried out on tuffs intercalated with Neogene volcano-sedimentary rocks in the Yenice-Saraycik area (Demirci, Manisa), Turkey. The tuffs are classified as peraluminous and they show calc-alkaline character. They represent mainly rhyolitic to rhyodacitic composition

A Study on Physicochemical Characteristics of Surface Waters in The Area of Dereli (Giresun, Turkey)

Some physicochemical characteristics of surface waters (main river and some streams) in the area of Dereli (Giresun) were investigated. Additionally, certain parameters and quality indices, which may affect the usability of waters for agriculture, were assessed. Available data indicate that the waters have slightly alkaline in character, with pH values ranging from 7.6 to 8.35. The waters are classified as fresh based on their EC values, which ranges from 210–590 µS/cm. The predominant anion in nearly all of the investigated waters is bicarbonate (HCO3-). Sulfate (SO42-) is, after bicarbonate, the second most abundant anion in the waters, followed by chloride (Cl−). Calcium (Ca2+) is the most abundant cation in the waters examined, followed by magnesium (Mg2+), sodium (Na+) and potassium (K+) in descending order. The levels of all ions examined in the waters are in the ranges recommended by the Food and Agriculture Organization (FAO) for irrigation water. Moreover, the calculated values of U.S. Salinity (SAR), Residual sodium carbonate (RSC), Sodium Percentage (Na %), Kelly’s ratio (KR) and Magnesium hazard (MH) indicate suitable of the waters for irrigation. In general, the surface waters in the locations studied are of good physicochemical quality, and also adequate for irrigation.Bu çalışmada, Dereli bölgesi yüzey sularının (ana nehir ve akarsular) bazı fizikokimyasal özellikleri incelenmiştir. Ayrıca, suların tarımsal sulama için kullanılabilirliğini etkileyebilecek bazı parametreler ve kalite indeksleri değerlendirilmiştir. Mevcut veriler, suların hafif alkali karakterde olduğunu ve pH değerlerinin 7.6 ile 8.35 arasında olduğunu göstermektedir. İncelenen sular 210-590 µS/cm arasında değişen EC değerlerine göre taze olarak sınıflandırılır. İncelenen suların neredeyse tamamında baskın olan anyon bikarbonattır (HCO3-). Sülfat (SO42-), bikarbonattan sonra sularda en bol bulunan ikinci anyondur ve bunu klorür (Cl−) takip eder. İncelenen sularda en bol bulunan katyon ise kalsiyum (Ca2+) olup, bunu sırasıyla magnezyum (Mg2+), sodyum (Na+) ve potasyum (K+) izlemektedir. Sularda belirlenen tüm iyon seviyeleri Gıda ve Tarım Örgütü (FAO)' nün sulama suları için önerdiği aralıktadır. Ayrıca, ABD Tuzluluğu (SAR), Kalıntı Sodyum Karbonat (RSC), Sodyum Yüzdesi (Na %), Kelly oranı (KR) ve Magnezyum Tehlikesi (MH) için hesaplanan değerler, suların tarımsal amaçlı sulama için uygun olduğunu göstermektedir. Genel olarak, incelenen lokasyonlardaki yüzey suları fizikokimyasal kimyasal olarak iyi kalitededir ve tarımsal amaçlı kullanım için elverişlidir
