    Relationship between internal carotid artery stenosis grade and optic nerve sheath diameter measured by transorbital ultrasonography
    (Wiley, 2021) Komut, Erdal; Murat, Muammer; Buyuksireci, Mehmet; Komut, Seval; Kozaci, Nalan
    Purpose To assess the consequence of the presence, grade, and asymmetry of carotid artery stenoses on the optic nerve sheath diameter (ONSD) measured by ultrasonography. Methods ONSD was measured with B-mode ultrasonography in 129 patients referred for duplex and color Doppler imaging of the carotid arteries. Internal carotid artery stenosis was graded on the basis of peak systolic flow velocity. Results The mean ONSD was 3.04 +/- 0.38 mm in the patients without or with 70% stenosis. There was an average difference of 0.58 mm between the ONSD of the patients with 70% stenosis. Conclusion ONSD is lower in patients with carotid artery stenosis. Carotid arteries should be investigated, especially in patients with cardiovascular risk factors or diseases, before interpreting ONSD values.

    The Measurement of Elderly Volunteers' Optic Nerve Sheath Diameters by Ocular Ultrasonography
    (Mdpi, 2019) Avci, Mustafa; Kozaci, Nalan; Komut, Erdal; Komut, Seval; Caliskan, Gulsum; Tulubas, Gul
    Background and objectives: The optic nerve is a component of the central nervous system, and the optic nerve sheath is connected to the subarachnoid space. For this reason, intracranial pressure (ICP) increases are directly transmitted to the optic nerve sheath. Knowing the normal optic nerve sheath diameter (ONSD) range in a healthy population is necessary to interpret this measurement as a sign of intracranial pressure in clinical practice and research. In this study, we aimed to determine the standard ONSD value in healthy adultsaged65 years of age or older who had not previously been diagnosed with a disease that could increase the ICP. Materials and Methods: The right and left ONSD values and ONSD differences were compared, according to the gender of the patients. The patients were divided into 3 groups, according to their age. The age groups were assigned as follows: Group 1: 65-74 years of age; Group 2: 75-84 years of age; and Group 3: 85 years of age or older. The ONSDs and the ONSD difference between the left and right eyes of Group 1, Group 2 and Group 3 were compared. Results: The study included 195 volunteers. The mean ONSD of both eyes was 4.16 +/- 0.69 mm, and the difference between the ONSD of the left and right eyes was 0.16 +/- 0.18 mm. There was no difference between genders in terms of right ONSD, left ONSD, mean ONSD and ONSD difference between the left and right eyes. There was no correlation between age and ONSD and ONSD difference. When the age groups and ONSD were compared, no difference was found between the groups. Conclusions: In conclusion, the ONSDs of both eyes do not vary with age in healthy adults aged65 years or older. ONSD does not vary between genders. The calculation of ONSD difference can be used to determine ICP increase.

    The Shetty Test’s Performance in Predicting Fractures in Radiography for Pediatric Patients
    (Erciyes University, 2023) Komut, Seval; Doğan, Burcu; Erenler, Ali Kemal
    Objective: The objective of this study was to determine the diagnostic performance of the Shetty test (ST) in predicting fractures in pediatric ankle trauma and to prevent unnecessary radiation exposure in these cases. Materials and Methods: The ST was administered to all the patients included in the study, and the cases were categorized as ST-positive and ST-negative. The sensitivity and specificity of the test were determined based on radiographic findings. Results: The distribution of trauma mechanisms of pediatric patients was as follows: sprain (65%, n=78), fall from height (20%, n=24), direct trauma (10%, n=12), and accidental hit (10%, n=12). Radiographically, 3 (2.5%) cases showed displaced fractures, 12 (10%) showed non-displaced fractures, 1 (0.8%) showed incomplete fractures, and 104 (86.7%) showed no fractures. The sensitivity of the Shetty Test was 75%, specificity was 59.6%, positive predictive value (PPV) was 22.2%, and negative predictive value (NPV) was 93.9% in predicting the need for radiography. Conclusion: The sensitivity and specificity of the ST in predicting fractures in pediatric patients with ankle trauma within the limits of radiographic indication were found to be lower than those for adults. However, due to limited information in the literature, further studies with larger cohorts are needed.
