(2018) Gok, M.; Aydin, E.; Güneyli, S.; Akay, A.; Cinar, C.; Oran, I.; 0000-0003-0907-3647; 28191625; AAI-8276-2021
AIM: Iatrogenic vascular injuries due to spinal surgeries are rare but serious complications. Surgical management of these injuries is challenging with high morbidity rates. In this study we aim to present the results of endovascular management of iatrogenic vascular injuries due to spinal surgeries. MATERIAL and METHODS: We retrospectively reviewed 11 patients (5 male, 6 female) who had vascular injuries due to cervical and lumbar spinal surgeries. Clinical findings were bleeding (n=5), leg edema (n=6) and right heart failure with severe dyspnea (n=1). The age range of the patients were between 42-67 (mean: 57.1). Six patients were reviewed with imaging before the procedures and the rest of the patients (n=5) were directly referred to the angiography unit for diagnosis and possible endovascular treatment. RESULTS: The types of surgeries were; cervical surgery (n=5) and lumbar disc operation (n=6). The type of vascular injuries were; vertebral artery stenosis (n=1), vertebral artery pseudoaneurysm (n=3), vertebral artery occlusion (n=1) and iliac arteriovenous fistula (n=6). The type of endovascular treatments were; parent artery occlusion (PAO) (n=2), covered stent graft implantation (n=6) and intrasaccular coil embolization of pseudoaneurysm (n=1). The remaining 2 patients were managed conservatively. No major complications or mortality occured during endovascular interventions. No bleeding or ischemia occured in the follow-up period. CONCLUSION: Iatrogenic vascular injuries due to spinal surgeries are rare but serious complications. Endovascular interventions are safe and effective in the diagnosis and treatment of such vascular injuries. © 2017, Turkish Neurosurgical Society.

(2018) Altin, C.; Erol, V; Aydin, E.; Yilmaz, M.; Tekindal, M. A.; Sade, L. E.; Gulay, H; Muderrisoglu, H.; https://orcid.org/0000-0002-3996-5681; https://orcid.org/0000-0003-3737-8595; https://orcid.org/0000-0002-0442-6178; https://orcid.org/0000-0003-0907-3647; https://orcid.org/0000-0002-9635-6313; https://orcid.org/0000-0002-2557-9579; 29571589; HGC-1839-2022; S-6973-2016; AAG-8233-2020; AAI-8276-2021; AAJ-6407-2021; AAQ-7583-2021
Background and aims: Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis. Methods and results: Patients were recruited for standard indications. A total of 105 patients (79 women and 26 men) with the mean age of 43.61 +/- 12.42 were prospectively enrolled. On Bmode duplex ultrasound; the mean CIMT at the far wall of both left and right common carotid arteries were measured. EFT was measured on the free wall of the right ventricle at enddiastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Delta (Delta) values were obtained by subtracting sixth month values from the baseline values. Body mass index (BMI) was significantly reduced from 46.95 +/- 7.54 to 33.54 +/- 6.41 kg/m2 (p < 0.001) in sixth months after LSG. Both EFT and CIMT were significantly decreased after surgery (8.68 +/- 1.95 mm vs. 7.41 +/- 1.87 mm; p < 0.001 and 0.74 +/- 0.13 mm vs. 0.67 +/- 0.11 mm; p < 0.001 respectively). A significant correlation between Delta EFT and Delta MI (r = 0.431, p < 0.001) was shown. Delta CIMT is significantly correlated with Delta EFT, Delta BMI and Delta systolic blood pressure (r = 0.310, r = 0.285 and r = 0.231 respectively, p < 0.05 for all). In multivariate stepwise linear regression analysis; among variables only Delta BMI was the independent predictor of Delta EFT (beta = 153, p = 0.001). Conclusion: Early atherosclerotic structural changes may be reversed or improved by sustained weight loss after LSG in asymptomatic obese patients.

Quantitative Analysis of the Olfactory System in COVID-19: An MR Imaging Study
(2021) Altunisik, E.; Baykan, A. H.; Sahin, S.; Aydin, E.; Erturk, S. M.; 34556477
BACKGROUND AND PURPOSE: Anosmia or hyposmia, often accompanied by changes in taste, is recognized as a common symptom that can assist in the diagnosis of coronavirus disease 2019 (COVID-19). The pathogenesis of olfactory dysfunction in COVID-19 is not yet fully understood. MR imaging represents a useful anatomic imaging method for the evaluation of olfactory dysfunction associated with varying etiologies, including viral infection, trauma, and neurodegenerative processes. This case-control study was conducted to compare quantitative measurements of olfactory anatomic structures between patients diagnosed with COVID-19 associated with persistent olfactory dysfunction and healthy controls. MATERIALS AND METHODS: This study has a retrospective design. Cranial MR imaging was performed on all participants in both the patient and control groups. The bilateral olfactory bulb volume, olfactory tract length, and olfactory sulcus depth were measured in all patients. RESULTS: A total of 116 people aged 18?60?years, including 36 patients diagnosed with COVID-19 and 80 controls, were included in the study. All measured values were compared between the patient and control groups. The right, left, and total olfactory bulb volume values were significantly lower in the patient group than in the control group. The patient group also had significantly lower right and left olfactory sulcus depth and olfactory tract length values compared with those in the control group. CONCLUSIONS: MR imaging findings can be used to demonstrate olfactory injury in patients with COVID-19. The olfactory pathway may represent an alternative route for virus entry into the central nervous system.

Objective: To examine the effects of Castellani's paint on symptomatic relief and skin flora in patients with an itchy external ear canal. Methods: Subjective pruritus scores, and erythema and desquamation scores, were noted in 61 patients with an itchy external ear canal. External ear canal skin swabs were taken for bacterial and fungal cultures. Patients were then randomly divided into three groups: either Castellani's paint (group one) or steroid ear drops (group two) were instilled, or non-impacted cerumen was removed (group three). Patients were re-assessed at one month after the initial visit. Results: After treatment, subjective pruritus scores were significantly lower in all groups, erythema scores were significantly decreased in group one, and desquamation scores were significantly reduced in groups one and two, when compared with pre-treatment scores. Reproduction density of bacteria including normal flora was decreased in group one. However, the types of bacteria that constitute the normal flora of the external ear canal were unchanged. Conclusion: Castellani's paint can be administered safely, effectively and easily, without affecting the type of external ear canal skin bacteria, in patients with an itchy external ear canal.
