Autoimmune Encephalitis and Musicogenic Epilepsy: a Case of Gad65 Antibody-Associated Seizure
(Wiley, 2025) Mohammadi-Asl, Ali; Bahadori, Amir Reza; Sabzgolin, Iman; Davari, Afshan; Razmafrooz, Mohammad; Tafakhori, Abbas; Ranji, Sara
Musicogenic epilepsy (ME) is a rare form of reflex epilepsy with a prevalence of 1 in 10,000,000. Recent research suggests a potential link between ME and autoimmune encephalitis, particularly involving glutamic acid decarboxylase 65-isoform (GAD65) antibodies. A 48-year-old female presented with a one-year history of music-triggered seizures. Her episodes were characterized by an initial aura followed by unresponsiveness and oral automatisms. Electroencephalography revealed abnormalities in the left anterior temporal lobe and temporal leads. Laboratory studies showed positive anti-GAD65 antibodies. The patient was treated with a combination of antiepileptic medication (Lamotrigine) and corticosteroids and intravenous immunoglobulin. This case contributes to the growing evidence supporting an association between ME and autoimmune mechanisms, particularly GAD65 antibody-mediated autoimmunity. It highlights the importance of screening autoimmune factors in ME patients and highlights the need for further research into targeted treatment strategies.
Can Super Resolution via Deep Learning Improve Classification Accuracy in Dental Radiography
(Oxford University Press, 2025) Celik, Berrin; Mikaeili, Mahsa; Genç, Mehmet Zahid; Çelik, Mahmut Emin
Objectives Deep learning-driven super resolution (SR) aims to enhance the quality and resolution of images, offering potential benefits in dental imaging. Although extensive research has focused on deep learning based dental classification tasks, the impact of applying SR techniques on classification remains underexplored. This study seeks to address this gap by evaluating and comparing the performance of deep learning classification models on dental images with and without SR enhancement. Methods An open-source dental image dataset was utilized to investigate the impact of SR on image classification performance. SR was applied by 2 models with a scaling ratio of 2 and 4, while classification was performed by 4 deep learning models. Performances were evaluated by well-accepted metrics like structural similarity index (SSIM), peak signal-to-noise ratio (PSNR), accuracy, recall, precision, and F1 score. The effect of SR on classification performance is interpreted through 2 different approaches. Results Two SR models yielded average SSIM and PSNR values of 0.904 and 36.71 for increasing resolution with 2 scaling ratios. Average accuracy and F-1 score for the classification trained and tested with 2 SR-generated images were 0.859 and 0.873. In the first of the comparisons carried out with 2 different approaches, it was observed that the accuracy increased in at least half of the cases (8 out of 16) when different models and scaling ratios were considered, while in the second approach, SR showed a significantly higher performance for almost all cases (12 out of 16). Conclusion This study demonstrated that the classification with SR-generated images significantly improved outcomes. Advances in knowledge For the first time, the classification performance of dental radiographs with improved resolution by SR has been investigated. Significant performance improvement was observed compared to the case without SR. © 2025 Elsevier B.V., All rights reserved.
Comparison of Posterior and Antero-Lateral Renal Tumors in Retroperitoneal Laparoscopic Partial Nephrectomy: a Propensity Score Matching Analysis
(Codon Publications, 2023) Anil, Hakan; Yildiz, Ali; Guzel, Ahmet; Akdemir, Serkan; Karamik, Kaan; Arslan, Murat
This study aimed to compare the antero-lateral and posterior localized renal masses in laparoscopic partial nephrectomy with the retroperitoneal approach in terms of operative, functional, and oncological outcomes. Patients who underwent retroperitoneal laparoscopic partial nephrec-tomy by a single surgeon between January 2013 and January 2021 were included in the study. A one-to-one propensity score matching (PSM) analysis was conducted to obtain two balanced groups. The patients were divided into two groups as posterior and antero-lateral according to the localization of the mass. A total of 239 patients were included in the PSM analysis, with 65 patients allocated to each group. The mean operative time was 79.2 & PLUSMN; 11.2 min in the posterior group, while it was 90.0 & PLUSMN; 11.6 min in the antero-lateral group (P < 0.001). Warm ischemia time was 15.9 & PLUSMN; 2.4 min in the posterior group and 18.6 & PLUSMN; 2.7 min in the antero-lateral group (P < 0.001). The median decrease in eGFR at 1 year was 4.8 (IQR, 2.9-6.9) mL/min in the posterior group and 5.0 (IQR, 2.8-11) mL/min in the antero-lateral group (P = 0.219). The warm isch-emia time and clamping technique were found to be significant factors for predicting eGFR change after surgery (13:0.693, 95% CI: 0.39-0.99, P < 0.001; 13:6.43, 95% CI: 1.1-11.7, P = 0.017, respectively). We report that retroperitoneal laparoscopic partial nephrectomy provided longer warm ischemia and operative time for antero-lateral renal masses than posterior masses. However, long-term oncological and functional results were similar for both localizations.
Factors Affecting the Level of Reflective Thinking and Clinical Decision-Making Skills in Medical Faculty Students
(Kare Publ, 2023) Senturk, Erol; Sarıkaya, Ozlem; Hafız, Aysenur Meric; Teker, Cenk
Objectives: The aim of this study is to evaluate the reflection skills of students at the Faculty of Medicine and the factors influenc- ing these skills, as well as to measure the impact of students' reflection skills on their clinical decision-making. Methods: This study is an educational research project conducted on fifth-year Ear Nose Throat (ENT) interns at Vakif University's Faculty of Medicine. The \"Reflective Thinking Level Determination Scale\" and the \"Clinical Decision-Making Scale,\" which are valid and reliable, were used to assess the reflection skills and clinical decision-making abilities of the 125 students participating in the study. Results: In our study, the mean score of the sub-dimensions of the Groningen Reflection Skills Scale was 77.04±5.14 for the fifth- year student population surveyed. Scores from the \"Self-Reflection\" and \"Reflective Communication\" sub-dimensions of the Gron- ingen Reflection Skills Scale were compared based on gender, participation in summer internships, receipt of scholarships, mem- bership in social sciences clubs, place of residence, school attended, diary-keeping habits, study styles, and cities of residence. Although there were some differences between the groups, these differences were not statistically significant. The total scores of the students on the Clinical Decision-Making Scale sub-dimensions ranged from 98 to 169, with a mean score of 146.18±10.97. A statistically positive and moderate correlation was found between the total scores of the participants on the Groningen Reflection Skills Scale and the total scores they obtained on the Clinical Decision-Making Scale (r=0.403; p=0.001). Conclusion: Consequently, an increase in the reflection skills of participants is associated with higher clinical decision-making scores. Reflection is the primary means of transitioning students from novices to experts, enhancing both comprehensive learning and learning experiences. Therefore, every medical school should develop a training program for student reflection, along with a feedback and assessment system integrated into the curriculum.
Human Papilloma Virus Frequency and Genotypes; Evaluation of the 4879 Screenings Made With Polymerase Chain Reaction and Chip Array Between 2001 and 2019 in Istanbul
(Kare Publ, 2021) Vural, Gurcan; Polat, Nedim
Objectives: The aim of this study is the documentation of human papilloma virus (HPV) frequency and types seen in the city of Istanbul, Turkey, as well as evaluation of the relationship between these subtypes and cytological and pathological diagnoses. Methods: 4879 cases were studied in our molecular pathology department between 2001 and 2019 in Istanbul. Between 2001 and 2010, 1692 cases were screened for HPV 6, 11, 16, 18, 31, and 33 by conventional hybridization and polymerase chain reaction (PCR). Since 2011, up to 49 HPV typing has been performed for 3187 cases with chip array. The cases were referred to the pathology center and the hospital pathology department by clinicians for screening before HPV vaccination and on the observation of precancerous changes and koilocyts in cytological-histopathological evaluations. Results: In this study, the frequency of HPV was found to be 10.8% (527 HPV-positive cases). Among these, 348 cases were high-risk groups, whether or not they were previously associated with a low-risk group. When we look at the distribution of the cases according to the high-risk HPV types, HPV 16 is the most common type. The frequencies of occurrence of other HPV types are as following: HPV-16: 41.7%, HPV-31: 11.7%, HPV-52: 7.9%, HPV-51: 7.1%, HPV-33: 6.9%, HPV-45: 6.5%, HPV-18: 6.3%, HPV-39: 6.1%, and HPV-58: 5.8%. It was further found that multiple infections were 28% of high grade squamous intraepithelial lesion cases. HPV frequency was 38% and 72%, respectively, in cases with cytologically or histopathological precancerous, low-grade squamous intraepithelial lesion, and HSIL changes. As a final note, HPV was detected in 9 of 10 cases with cervical cancer (90%). Only 1 adenocarcinoma case detected in the series was a double infection with HPV types 18 and 45. Conclusion: HPV 16 was the most common type found in this study. It is followed by types 31, 52, 51, 33, 45, 18, 39, and 58, respectively. The most common association observed in double infections was between HPV 16 and 58. It was also observed that the incidence of HPV in the city of Istanbul, Turkey, was similar to other developed countries. As a final note, in addition to screening tests, PCR and chip array studies should be conducted and the community should be informed about preventive medicine and the importance of condom use.

(Turkish Neuropsychiatry Assoc-turk Noropsikiyatri dernegi, 2024) Vatansever, Büşra Kuzgun; Büyükgök, Deniz; Aypak, Oya Çelik; Şahin, Doğan; Ercis, Mete; Ercis, Mete
Amaç: Bu çalışma, Sınır Kişilik Bozukluğu (SKB) tanılı bireylerde karar verme süreçlerini nöropsikolojik testlerle değerlendirerek, SKB’ye özgü bilişsel özelliklerin karar verme süreçleriyle ilişkisini sağlıklı kontrollerle karşılaştırarak incelemeyi hedeflemektedir. Yöntem: Çalışmanın örneklemi SKB tanılı hasta grubu (n=27) ile psikiyatrik tanısı olmayan sağlıklı katılımcılardan (n=28) oluşmaktadır. Hastalık şiddetinin değerlendirilmesi için Borderline Kişilik Envanteri (BKE), nöropsikolojik değerlendirme için Iowa Kumar Testi (IKT), Stroop Testi, Benton Yüz Tanıma Testi, Gözlerden Zihin Okuma Testi, Dokuz Eylül Zihin Teorisi Ölçeği (DEZTÖ), WMS-R Sayı Menzili ve Mantıksal Bellek Alt Ölçeği uygulanmıştır. Bulgular: SKB grubu ile kontrol grubu arasında BKE puanlarında anlamlı düzeyde farklılık izlenmektedir (p=0,02). Stroop Testi’ndeki enterferans süresi ve hata sayıları açısından gruplar arası anlamlı bir fark izlenmezken, spontan düzeltme cevap sayılarının anlamlı düzeyde farklılık taşıdığı (p=0,02) gözlenmiştir. WMS-R Mantıksal Bellek alt testi A hikâyesinin anlık hatırlama puanlarında gruplar arasında fark olduğu (p<0,01) tespit edilmiştir. IKT’de ilk yarıda A destesinden (p=0,028) son yarıda ise B destesinden (p=0,03) seçme eğiliminde gruplar arasında fark izlenmektedir. Son olarak, DEZTÖ’de iki grup arasında toplam puanda (p<0,01) izlenen anlamlı farkın 2. derece yanlış inanç (p=0,024) ve empati (p=0,027) görevlerinde ortaya çıktığı görülmüştür. Sonuç: Çalışmamız örneklemini oluşturan SKB tanılı bireylerin uygunsuz cevabın inhibisyonunda minimal güçlüğe sahip oldukları, bu güçlüğün karar verme davranışında dezavantajlı seçimler yapmayla ilişkili olduğu sonucuna ulaşılmıştır. Ayrıca, SKB tanılı bireylerin dışsal ipuçlarından zihinsel durumları yordamada başarılı oldukları fakat sosyal bir örüntü dâhilinde ipuçlarını bütünleştirme ve uyumlu öyküleştirme yapmakta zorlandıkları görülmüştür.

(Aves, 2021) Yildiz, Ali; Akdemir, Serkan; Anil, Hakan; Arslan, Murat
Objective: This study aimed to assess the perioperative and the 12-month efficacy and safety of 140 W high-powered holmium laser for enucleation of the prostate (HP-HoLEP) for the treatment of benign prostatic obstruction. Material and methods: The data of 540 patients who underwent HoLEP by a single surgeon were analyzed retrospectively. Preoperative evaluation included a physical examination with a digital rectal examination, measurement of maximum urinary flow rate (Q(max)), postvoid residual volume (PVR) and prostate volume by transabdominal ultrasonography, serum prostate-specific antigen (PSA), international prostate symptom score (I-PSS) and international index of erectile function-5 (IIEF-5) questionnaires, and urine analysis. Morcellation, enucleation, and operation efficiencies were calculated with the resected weight divided by morcellation, enucleation, and operative times, respectively. The patients were reassessed at 1, 3, 6, and 12 months after surgery by I-PSS, IIEF-5, Q(max), PSA, and the occurrence of complications. Results: The mean operative time was 65.2 +/- 20.9 minutes. The mean enucleation time and efficiency were 53 +/- 15.1 minutes and 1.72 +/- 0.4 g/min, respectively. The mean morcellation time and efficiency were 12.3 +/- 15.1 minutes and 7.4 +/- 3.2 g/min respectively. Clavien grade 1 complications were observed in 102 (18.9%) patients, Clavien grade 2 complications in 20 (3.7%) patients, and Clavien grade 3b complications in 23 (5.4%) patients. I-PSS, Q(max), and IIEF-5 at postoperative 1, 3, 6, and 12 months were significantly better than baseline results. Conclusion: Our study demonstrated that 140 W HP-HoLEP can be performed with high enucleation efficiency, low perioperative and postoperative complication rates, and excellent functional results.
