Central Diabetes Insipidus Following Intracranial Hemorrhage Due To Vitamin K Deficiency in a Neonate
(2005) Çaksen, H.; Odabaş, D.; Kaya, A.; Cesur, Y.; Kiymaz, N.; Etlik, Ö.; Turhan, S.
A previously healthy 30-day-old girl presented with seizures, irritability and inability to sleep for three days. Vitamin K was not given just after birth. She was lethargic. A multifocal clonic seizure was evident during examination. Anisocoria was diagnosed on eye examination. Brain magnetic resonance imaging showed intracerebral hemorrhage, ventricular dilatation, and hematoma in the left temporofrontal region extending to the hypothalamus. Central diabetes insipidus was diagnosed by water deprivation due to dehydration and hypernatremia, and then desmopressin was added to phenobarbital. The possible mechanism of central diabetes insipidus in our patient is damage of vasopressin pathway resulting from compression of hemorrhage. An operation of ventriculoperitoneal shunt was also performed due to hydrocephalus. While she was symptom-free except for neurological sequel during routine control examinations after discharging from hospital, the parents said that she died, most probably from bronchopneumonia, at the age of 7.5 months. In conclusion, we emphasize that prophylactic vitamin K should be administrated to all babies just after birth, and infants with intracranial hemorrhage should carefully be monitored for central diabetes insipidus.
Radionuclide Determination and Radioactivity Evaluation of Surface Soil Samples Collected Along the Ercek Lake Basin in Eastern Anatolia, Turkey
(Elsevier, 2014) Yildiz, N.; Oto, B.; Turhan, S.; Ugur, F. A.; Goren, E.
In the present study, the mean activity concentrations of U-238, Th-232, K-40 and fission products Cs-137 in the soil samples measured by using high-purity germanium gamma spectrometry were 18.9, 27.2, 524.0 and 10.6 Bq kg(-1), respectively. The activity results were analyzed for frequency distribution, tabulated and compared with Turkey and worldwide literatures. Radiological risk evaluation was done by calculating absorbed gamma dose rate in outdoor air and the corresponding annual effective dose due to external exposure to radionuclides distributed in soil. The mean values of the outdoor gamma dose rates and the external annual effective doses received by members of the public from terrestrial radiation and Cs-137 were estimated at 47 nGy h(-1) and 0.6 nGy h(-1) and 57.7 mu Sv and 1.2 mu Sv, respectively.
