Cerebral Hemiatrophy Associated With Hematological and Developmental Disorders
(2004) Ünal, Ö.; Çaksen, H.; Kiymaz, N.; Dilek, I.; Kayan, M.; Anlar, Ö.
The etiology of cerebral hemiatrophy may be congenital or acquired. Trauma, infection, vascular abnormality, ischemic and hemorrhagic conditions may be the etiologic factors in acquired type. There is limited information about its association with other disorders in the literature. We presented three new cases of cerebral hemiatrophy associated with some hematological and developmental disorders. Cerebral hemiatrophy was associated with thalassemia major in a 10-year-old girl, acute myeloblastic leukemia and Marfan syndrome in a 23-year-old man, and craniosynostosis in a 1-year-old boy. To the best of our knowledge, thalassemia major, myeloblastic leukemia, Marfan syndrome and craniosynostosis have not been reported in cerebral hemiatrophy in the literature. © 2004, IOS Press.

Compressive Effect of Large Persistent Trigeminal Artery Upon Pituitary Gland: Importance of Mri and Mra
(Elsevier BV, 2004) Harman, M.; Kýymaz, N.; Ayakta, H.; Kayan, M.
Persistent trigeminal artery (PTA) is a relatively frequent type of carotid-basilar anastomosis. Most of PTA has no symptoms and are noticed incidentally. We report a case of PTA compressing the right side pituitary gland, in a patient with hormonal disorder. In this report, we emphasize importance of MR imaging and MR angiography on demonstrating the relationship between the pituitary gland and PTA. © 2004 Elsevier Ireland Ltd. All rights reserved.
The Prevalence of Urinary Lithiasis in Children in Van Region, Turkey
(2009) Akgün, C.; Kayan, M.; Tuncer, O.; Arslan, Ş.; Çaksen, H.; Ataş, B.; Akbayram, S.
We aimed to determine the prevalence and etiology of urinary lithiasis in childhood in our region, Van, Turkey. A total of 1120 children were included in the study. Urinary ultrasonography was performed in all the children between April 2003 and June 2003. During the study, the kidneys were examined longitudinally and transversally using a 3.75 MHz convex probe in a Hitachi EUB -315 ultrasonography machine. The children's ages ranged from 7 years to 14 years (10.16 ±1.92 years) and 572 (51.1%) were males and 548 (48.9%) females. Urinary ultrasonography showed that 19 (1.7%) children had urinary lithiasis, which was in the right kidney in 15 children and in the left kidney in four children. Urinary lithiasis was in the upper urinary tract in all children. The etiological studies showed metabolic disorder in 14 children, and congenital renal anomaly in one child, but no underlying cause was diagnosed in four children. In conclusion, we found that was the prevalence of urinary lithiasis was 1.7% in school-aged children in our region. It was also noted that all urinary lithiasis was in the upper urinary system and its most common cause was metabolic disorder.
