Item Tuberous sclerosis complex; a single center experience(2015) Erol, Ilknur; Savas, Tulin; Sekerci, Sevda; Yazici, Nalan; Erbay, Ayse; Demir, Senay; Saygi, Semra; Alkan, Ozlem; 26078697Aim: This study was planned with the aim of retrospectively reviewing the clinical and laboratory findings and therapies of our patients diagnosed with tuberous sclerosis and redefining the patients according to the diagnostic criteria revised by the 2012 International Tuberous Sclerosis Complex Consensus Group and comparing them with the literature. Material and Methods: 20 patients diagnosed with tuberous sclerosis complex in the Pediatric Neurology Clinic were examined retrospectively in terms of clinical findings and therapies. The diagnoses were compared again according to 1998 and 2012 criteria. Results: It was observed that the complaint at presentation was seizure in 17 of 20 patients and hypopigmented spots on the skin in 3 of 20 patients. On the initial physical examination, imaging findings related with the disease were found in the skin in 17 of the patients, in the eye in 5, in the kidneys in 7 and in the brain in 17. No cardiac involvement was observed in the patients. Infantile spasm was observed in 7 of the patients who presented because of seizure (n=17), partial seizure was observed in 7 and multiple seizure types were observed in 3. It was found that sirolimus treatment was given to 9 of 20 patients because of different reasons, 7 of these 9 patients had epileptic seizures and sirolimus treatment had no effect on epileptic seizures. According to 2012 diagnostic criteria, no marked change occured in the diagnoses of our patients. Conclusions: It was observed that the signs and symptoms of our patients were compatible with the literature. Molecular genetic examination was planned for the patients who were being followed up because of possible tuberous sclerosis complex. It was observed that sirolimus treatment had no marked effect on the seizure frequency of our patients.Item Prognostic Impact of Histologic Subtype in Non-Small Cell Lung Cancer Patients Treated with Gamma Knife Radiosurgery: Retrospective Analysis of 104 Patients(2017) Tufan, Kadir; Aydemir, Fatih; Cekinmez, Melih; Kardes, Ozgur; Sarica, Feyzi Birol; Topkan, Erkan; Sonmez, Erkin; Alkan, Ozlem; Ugurluer, Gamze; Altınors, Nur; 0000-0002-5693-3542; 0000-0003-2854-941X; 0000-0001-8120-7123; 0000-0003-1509-4575; 0000-0001-9658-9005; 0000-0001-9985-0184; 27593758; AAI-8820-2021; P-5895-2018; AAG-2213-2021; AAK-1686-2021AIM: In this study, factors affecting survival, local failure, distant brain failure, whole brain failure and whole-brain radiation therapy (WBRT) free survival according to histological subtypes were investigated in patients with brain metastases from non-small cell lung cancer (NSCLC). MATERIAL and METHODS: Patients with positive pathology reports for adenocarcinoma (ACA) and squamous cell carcinoma (SCC) were included in the study. Seventy-eight ACA and 26 SCC patients were included in the study. Patients with previous history of cerebral metastasis surgery and WBRT were excluded from the study. RESULTS: The median survival was calculated as 12.6 months for patients with ACA and 5.9 months for patients with SCC. One-year distant brain failure was calculated as 65.1% in ACA patients and 39.6% in SCC patients. One-year whole brain failure was calculated as 58.1% in ACA patients and 39.6% in SCC patients. The one-year freedom from WBRT rate was calculated as 72.8% in ACA patients and 56.3% in SCC patients. SCC histology was considered as a significant factor in deterioration of overall survival in multivariate analysis. SCC histology, the increase in the number of metastases and RPA class were factors that caused an increase in distant brain failure. Also, SCC histology, the increase in the number of metastases and RPA class were factors that caused an increase in whole brain failure. CONCLUSION: SCC histology may be an important prognostic factor for overall survival. Also, due to high distant brain failure rate in SCC histology, WBRT can be added to treatment early.Item Endovascular Treatment of a Patient with Moyamoya Disease and Seckel Syndrome: A Case Report(2018) Andic, Cagatay; Gunesli, Aylin; Alkan, Ozlem; Erol, Ilknur; Suner, Halil Ibrahim; 30090148Seckel syndrome and Moyamoya diseases are different entities that rarely associated with each other. Several cases presenting with both these diseases were reported. Intracerebral artery aneurysms and collateral vessels can be seen with Moyamoya. They are commonly treated with medical treatment. We present a 12-years old patient with both Seckel syndrome and Moyamoya disease presented with middle cerebral artery aneurysm which was treated with endovascular modalities.Item Complications of Formaldehyde Injection for a Cystic Mass of the Neck(2018) Caylakli, Fatma; Yilmaz, Ismail; Alkan, Ozlem; 30197813Formaldehyde is a colorless reactive chemical with suffocating and pungent odor. It is irritant to mucous membranes and can enter the body by either oral ingestion or inhalation. Formaldehyde is toxic to living tissue. In this report, we present the case of a 22-year-old woman who was treated with formaldehyde injection for a cystic mass of the neck with developing complications.
