    Central nervous system variations and abnormalities in anhidrotic ectodermal dysplasia (aed): Neuroimaging findings
    (Sage Publications Ltd, 2020-01-30) Dusak, Abdurrahim; Hafizoglu, Demet; Kilic, Sara Sebnem; Yazici, Zeynep; 0000-0002-4363-5861; 0000-0001-8571-2581; AAH-1658-2021; AAI-2303-2021
    Background Anhidrotic ectodermal dysplasia (AED) is a rare, mostly X-linked recessive genodermatosis, characterized by congenital defects of ectodermal derivative structures as the central nervous system (CNS) is primarily ectodermal in origin. Purpose To evaluate CNS variations and abnormalities in AED. Material and Methods A retrospective analysis was made of the neurological and neuroimaging findings of 17 children (12 boys, 5 girls; median age = 8 years; age range = 2-14 years) diagnosed with AED in our pediatric clinics during 2008-2016. The pattern of CNS variation and abnormalities were evaluated by comparing of these findings with an age- and gender-matched healthy control group with no family history. Results Of the 17 AED cases identified on the basis of neuroimaging findings, 6 (35.3%) were seen to be normal. Associated CNS variation and abnormalities including cavum septum pellucidum (35.3%), callosal dysgenesis (11.8%), prominent Virchow-Robin spaces (64.7%), cortical sulcal dilation (41.1%), mega cisterna magna (35.3%), focal cortical dysplasia (11.8%), and delayed myelination (58.8%) were observed in 11 (64.7%) children with AED. Conclusion AED suggests a spectrum of CNS variation and abnormalities, presenting with neurological and neuroimaging findings, demonstrated in the embryonic surface- and neuro-ectoderm derived structures. The results of this study suggest that CNS variation and abnormalities might be associated with AED.

    Diagnosis and endovascular treatment of acute thromboembolic renal artery occlusion presenting with abdominal pain
    (Springer, 2012-10) Dusak, Abdurrahim; Eryılmaz, Nalan Y.; Gönen, Aysun; Hakyemez, Bahattin; Dilek, Kamil; Erdoğan, Cüneyt; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Nefroloji Anabilim Dalı.; 0000-0002-3425-0740; A-7826-2019; AAI-2318-2021; 6507393726; 55191388500; 26655524000; 6602527239; 56005080200; 8293835700
    Acute renal artery thromboembolic occlusion is seldomly encountered with respect to other central and peripheral ones. Patients may present with non-specific abdominal pain and renal colic. Organ functions can be preserved by means of endovascular treatment when early diagnosis is possible. Acute occlusion of renal arteries must be considered in the differential diagnosis of acute flank pain. This paper presents successful endovascular treatment of thromboembolic renal artery occlusion in two cases.

    Magnetic resonance spectroscopy findings of pyogenic, tuberculous, and cryptococcus intracranial abscesses
    (Springer, 2012-02) Dusak, Abdurrahim; Hakyemez, Bahattin; Kocaeli, Hasan; Bekar, Ahmet; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Beyin Cerrahisi Anabilim Dalı.; 0000-0002-3425-0740; AAI-2318-2021; 6602527239; 6603500567; 6603677218
    Proton magnetic resonance spectroscopy (MRS) complements conventional methods used to differentiate intracranial cystic lesions. We report MRS findings of three cases that were diagnosed as pyogenic, tuberculous, and Cryptococcus abscesses before instituting any medical or surgical therapy. The pyogenic brain abscess had typical specific spectral findings (i.e., the demonstration of amino acids). Lactate and lipid peaks were visible in the tuberculous abscess. Cryptococcus neoformans can appear differently in different brain regions, which may lead to different spectral findings.

    Progressive cerebroretinal microangiopathy with calcifications and cysts syndrome: An unusual cause of complex partial seizure
    (Wiley, 2012-08) Dusak, Abdurrahim; Seferoğlu, Meral; Hakyemez, Bahattin; Bora, İbrahim; Parlak, Müfit; Uludağ Üniversitesi/Tıp Fakültesi/Nöroloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0002-3425-0740; AAI-2318-2021; AAG-8521-2021; 25636262100; 6602527239; 6602914249; 7003589220
    Syndrome is characterized by cerebral calcification andcyst formation (CRMCC), as defined in recent years,1and isdescribed in the published reports as Coats plus syndrome,Labrune syndrome and leukoencephalopathy calcification andcysts (LCC) syndrome.2Cerebral, ophthalmic, skeletal, intesti-nal involvement can be seen. CRMCC determined in lateadolescence is limited. Autosomal recessive inheritance isreported.3In the majority of patients, neurological findingsshowing progression have been reported, such as spasticity,dystonia, ataxia and loss of cognitive abilities. Imaging find-ings with laboratory data should support the diagnosis.
