S.; Tuncel, R.; Ozdemir, N.; Baklaci, M.; Ekmekci, O.; Saygili, F.Introduction. Fahr's syndrome is an infrequent disorder characterized by bilateral symmetrical calcification of basal ganglia and the cerebral cortex. It can be seen genetic, idiopathic, or secondary to endocrine diseases. This disease is related to different metabolic disorders particularly with diseases of the parathyroid gland. Case 1. A 63-year-old female patient applied to our clinic due to having hypoparathyroidism with bilateral basal ganglia calcification in head computed tomography(CT). She had subtotal thyroidectomy 25 years ago. in the neurological examination, mild symmetrical parkinsonism was determined. in laboratory examination Ca:8 mg/dL (8.6- 10.2), P:5.1 mg/dL (2.3-4.5), PTH:9.53 pg/mL (15-65) were detected. Calcitriol 0.25 mu/day was added to her treatment. Her parkinsonism disappeared after the treatment. Case 2. A 49-year-old male patient was consulted when he was admitted to the department of neurology in our hospital. the physical examination demonstrated the characteristics of Albright's hereditary osteodystrophy. the neurological examination shows bilateral symmetrical bradykinesia, dysphagia, and moderate dysarthria. in the laboratory examination PTH: 46.5 ng/L(15-65), Ca:8.6 mg/dL (8.6-10.2), P:2.7 mg/dL (2.3-4.5) were detected and were all within the normal ranges. Consequently, pseudopseudohypoparathyroidism was decided as a diagnosis. G protein alpha subunit mutation (Gs alpha) was not detected due to technical limitations. Conclusion. When a patient is diagnosed as Fahr's syndrome, we should keep in mind parathyroid disorders. Fahr's syndrome must be evaluated in patients showing intracranial calcification accompanied by parathyroid diseases.Öğe Sensory ataxic neuropathy with dysarthria and ophthalmoparesis: seven case reports(Pergamon-Elsevier Science Ltd, 2019) Karasoy, H.; Tuncel, R.; Ekmekci, O.; Yuceyar, A.; Bademkiran, F.; Onay, H.Öğe Spinal ischaemic stroke: clinical and radiological findings and short-term outcome(Wiley-Blackwell, 2011) Kumral, E.; Polat, F.; Gulluoglu, H.; Uzunkopru, C.; Tuncel, R.; Alpaydin, S.Background and purpose: The mechanism and pathogenesis of ischemic spinal stroke remain largely undetermined because most clinical studies have included mostly patients without a systematic study of associated vascular and concomitant disease of the vertebral body. Therefore, we assessed the pathogenetic mechanisms and short-term outcomes of the patients with spinal stroke based on clinical data and magnetic resonance imaging findings. Methods: We studied clinical, imaging, and outcome data for 36 patients with acute spinal stroke admitted between 1998 and 2008. There were 16 men and 20 women (mean age 73, range 56-85 years). Results: Twelve patients (33%) had anterior spinal artery patterns, 8 (22%) had anterior and 6 (17%) had posterior unilateral infarct, 5 (14%) had posterior spinal artery infarct pattern, 3 (8%) had central involvement, and 2 (5%) had transverse syndrome. Twelve patients (33%) had no cause of stroke. Patients with central infarct and transverse infarct had a high frequency of peripheral vascular disease and prolonged hypotension, and one patient each had a chronic spinal disease. The onset of all other infarcts was associated with mechanical triggering movements in 12 patients (41%, P < 0.05), and with diseases of the spine in 19 (66%; P < 0.001), with the clinical picture suggesting root involvement at the level of the spinal cord ischemia. The short-term outcomes were favorable in two-thirds of patients, while 25% of them did not show any recovery on leaving the hospital. Conclusion: The most common type of spinal cord ischemia is bilateral or unilateral anterior spinal artery infarcts due to radicular artery disease with acute or chronic spinal disease and followed by central and transverse infarcts due to extensive spinal cord hypoperfusion and arteriopathy.
