Benign paroxysmal positional vertigo after radiologic scanning: a case series

<p>Abstract</p> <p>Introduction</p> <p>Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo. It is frequently seen in elderly patients, and the course of the attack may easily mimic cerebrovascular disease. A BPPV attack after a radiologic examination has not been reported previously. We report the cases of two patients who had BPPV attacks after radiologic imaging.</p> <p>Case presentation</p> <p>The first patient with headache and tremor was admitted to the radiology department for cranial computed tomography (CT) imaging. During scanning, she was asked to lie in the supine position with no other head movements for approximately 10 minutes. After the cranial CT imaging, she stood up rapidly, and suddenly experienced a vertigo attack and nausea. The second patient was admitted to the radiology department for evaluation of his renal arteries. During the renal magnetic resonance angiography, he was in the supine position for 20 minutes and asked not to move. After the examination, he stood up rapidly with the help of the technician and suddenly experienced a vertigo attack with nausea and vomiting. The results of standard laboratory analyses and their neurologic examinations were within normal limits and Dix-Hallpike tests showed rotatory nystagmus in both cases. An Epley maneuver was performed to the patients. The results of a control Dix-Hallpike tests after 1 Epley maneuver were negative in both patients.</p> <p>Conclusion</p> <p>Radiologists and clinicians must keep in mind that after radiologic imaging in which the patient is still for some time in the supine position and then helped to stand up rapidly, a BPPV attack may occur.</p

Effect of Deficit Irrigation Regimes on Yield and Fruit Quality of Olive Trees (cv. Memecik) on the Aegean Coast of Turkey

WOS: 000417575500013In this study, six different irrigation treatments were applied to an olive orchard using the drip irrigation method. Five of these were arranged according to 25% (S-0.25), 50% (S-0.50), 75% (S-0.75), 100% (S-1.00) and 125% (S-1.25) of the evaporation in 5days of a class A' evaporation pan, and one control (S-C) was arranged so as to bring the reducing moisture at a soil depth of 0-90cm to field capacity. Yield values were not affected by the irrigation treatment (p>0.05). In contrast, 100-fruit weight, pulp ratio, hardness moisture, oil, reducing sugar content and bitterness were affected by irrigation (p<0.05). Generally, an increase in the amount of irrigation water given in the study was accompanied by a fall in ripeness index values, a rise in moisture content, and a reduction in the oil content of fruit. The highest content of reducing sugar was obtained from S-0.25, generally being lower with increase in the water applied. The findings show that application of 25% of the evaporation of a class A' evaporation pan (treatment S-0.25) can be recommended for cv. Memecik. Application of this recommendation can achieve a 72% saving in water and make a significant contribution to the conservation of limited water resources.

Determination of deficit irrigation treatments on olive fruit quality and olive oil (Memecik cv.) chemical composition and antioxidant properties

###EgeUn###In this research, the influences of irrigation treatments (K1, K2, K3, K4, K5) on chemical properties, antioxidant compounds and activities of table olive and olive oils (Memecik) were investigated during three crop seasons (2012/13, 2013/14 and 2014/15). The three least irrigated (K3, K4 and K5) and non -irrigated (K1) regimes indicated that higher content of polyphenols of olive fruits were those with the most irrigated regime (K2). According to L", a* and b", results of statistical differences were determined between the treatments of K1 and K5 (P<0.05). There was no significant effect determined between irrigation treatments of the Memecik olive oil main fatty acids such as palmitic (C16:0), oleic (C18:1) and linoleic (C18:2) acid, except palmitic acid (first year) and linoleic acid (second year). When we look at the triacylglycerol (TAG) composition in the 2012/13 and 2013/14 crop seasons important statistical differences were determined between the irrigation treatments on some TAG contents (P<0.05) however these differences between irrigation treatments, although statistically significant, are very slight. During the last crop season, no significant effects were determined in the TAG composition between irrigation treatments. During the first and the second year, important statistical differences were observed between the irrigation treatments both for the total phenol content and bitterness index (K225) value of oils (P<0.05). The research showed that the K225 value of Memecik olive oils is above 0.360 value. Important differences were determined between the irrigation treatments on the alpha tocopherol content (P<0.05). DPPH' (2,2-diphenyl-1-picrylhy-drazyl) content (first and second year) and ABTS'+ (2,2-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid) content (all crop seasons) were also significantly influenced by irrigation treatments due to changes in antioxidant compounds (P<0.05). Whereas all these differences, although statistically important, are very slight. In the light of the findings of this research, it was concluded that the use of the restricted irrigation regimes enabled water to be saved with very slight change in fruit and oil quality.TUBITAK (The Scientific and Technological Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [1120317]; TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)This study was supported by TUBITAK (The Scientific and Technological Research Council of Turkey) under project number 1120317.
