Item Reliability of Real-Time Sonoelastography in the Diagnosis of Supraspinatus Tendinopathy(2021) Aydin, Elcin; Soylev, Gozde Ozcan; Muratli, Sedit Kivanc; Limnili, Bora Bora; Boya, Hakan; Tekindal, Mustafa Agah; Agildere, Muhtesem; 0000-0001-8742-5543; 0000-0001-8742-5543; 31107427; AAI-8276-2021; AAJ-4917-2021The practicality of real-time sonoelastography in the diagnosis of tendinopathy is being discussed since the beginning of its use in musculoskeletal system. The aims of this study were to compare the elasticity of pathologic supraspinatus tendon with the uninvolved side by sonoelastography and to determine the relationship between the sonoelastographic findings and magnetic resonance imaging (MRI) grade of the tendinosis. Eighty-2 patients (50 males, 32 females, mean +/- SD age = 53.61 +/- 16.15 years, range = 20-84 years) with unilateral supraspinatus tendinosis were included in this study. Three grades of tendinosis were identified in MRI (grade 1: mild, grade 2: moderate, and grade 3: severe). The strain ratio (SR) of the tendinosis area to the healthy normal area of the same tendon tissue and SR of the tendinosis area to ipsilateral subcutaneous fat tissue were evaluated with sonoelastography. The SRs of the tendinosis areas were also compared with the control (contralateral) side tendon tissue and subcutaneous fat tissue of the same patients. Between-groups comparisons were also done according to the MRI grading. Statistical analysis was done using paired t test (P < 0.005 was considered statistically significant). There was a statistically significant difference in the comparison of the SRs of the tendinosis areas to subcutaneous fat tissues on ipsilateral shoulders (TA/SFT) and the healthy supraspinatus tendon area (TA/ST) of the same shoulder. There was also statistically significant difference when compared with the control side measurements (P < 0.01). In patients who have grade 1 and grade 3 tendinosis on MRI, there was statistically significant difference between elastrographic evaluation of affected and unaffected sides. Real-time sonoelastography is a reliable diagnostic method in patients with rotator cuff tendinosis and shall be kept in mind as a noninvasive, inexpensive, and practical diagnostic test in suitable cases.Item Investigation of relationship between colour discrimination ability and stereoscopic acuity using Farnsworth Munsell 100 hue test and stereo tests(2020) Koctekin, Belkis; Coban, Deniz Turgut; Ozen, Mehmet; Tekindal, Mustafa Agah; Unal, Ayse Cengiz; Altintas, Ayse Gul Kocak; Gundogan, Nimet Unay; 31712007Objective: To evaluate the effect of colour discrimination ability on the stereoscopic acuity by comparing individuals having congenital colour vision deficiency (CCVD) with healthy individuals. Design: A comparative study. Participants: The study included 53 binocular males, of whom 26 (mean age, 36.04 +/- 9.30 years) were in the healthy group and 27 (mean age, 33.04 +/- 9.81 years) were in the CCVD group. Methods: The following tests were used: the Ishihara pseudo-isochromatic plate test for detecting CCVD, the Farnsworth Munsell 100 (FM100) hue test for colour discrimination ability, the TNO and Titmus stereo tests for stereoscopic acuity. Results: In the CCVD group, 20 males were deutan and 7 males were protan. According to the FM100 hue test, total error score (TES), blue/yellow (b/y) local error score (LES), and red/green LES were significantly lower in the healthy group (30.23 +/- 18.78, 15.15 +/- 10.38, and 13.88 +/- 11.93, respectively) than in the CCVD group (133.59 +/- 67.45, 41.15 +/- 22.03, and 89.15 +/- 52.16, respectively) (p < 0.01 for each). The stereo test scores revealed significantly higher stereoscopic acuity in the healthy group (43.85 +/- 33.92 arcsec for the TNO test and 40.00 +/- 0.00 arcsec for the Titmus test) than in the CCVD group (93.33 +/- 90.51 arcsec for TNO stereo test and 52.96 +/- 24.62 arcsec for the Titmus test) (p < 0.05 for each). The TNO test score was significantly and positively correlated with the TES (r = 0.390, p = 0.049) and b/y LES (r = 0.490, p = 0.011) in the healthy group. Conclusions: Colour discrimination ability affected stereoscopic acuity. Moreover, stereoscopic acuity increased with increasing colour discrimination ability, which could be originated from the b/y colour region.Item Gut dysbiosis may be associated with hyperemesis gravidarum(2020) Balci, Serdar; Tohma, Yusuf Aytac; Esin, Sertac; Onalan, Gogsen; Tekindal, Mustafa Agah; Zeyneloglu, Hulusi Bulent; 0000-0001-9418-4733; 0000-0002-0289-2642; 0000-0002-1782-7325; 0000-0001-9577-4946; 32519907; AAE-6482-2021; B-6487-2009; AAJ-1097-2021; AAI-8810-2021Purpose:In this study, we aimed to determine the frequency of different intestinal microorganisms of patients with normal pregnancies and HG and to compare these frequencies between the two groups. Materials and methods:This case-control study was carried out in Baskent University Department of Obstetrics and Gynecology and included 20 patients; 10 of whom had normal pregnancies and 10 of whom had HG. A stool flora scan was routinely planned for all patients. Transient and continuous fecal bacteria and fungal flora were analyzed. All data were evaluated statistically and their relationships with clinical condition were discussed. Results:The study group consisted of 20 pregnant women with a mean age of 31.5 years. All patients were nonsmokers and free of chronic diseases and of any medications. Aerobic and anaerobic bacteria groups, fungal colonies, and parasites were examined and bowel pH values were measured separately for each patient. Bacterial and fungal species outside the reference ranges were recorded for each patient. There was a statistically significant increase inClostridiumspp. (p:.01) andCandidaspp. (p:.033) and a statistically significant decrease inBifidobacteriumspp.(p:.008) in patients with HG compared to women with normal pregnancies. There was a significant difference between the group with HG and the group with normal pregnancies in terms of flora dysbiosis (p:.001). Conclusion:Our results suggest that gut dysbiosis may be a factor in HG. The effect of the severity of gut dysbiosis on the disease may be the subject of future studies.Item The sensitivity and specificity of the balance evaluation systems test-BESTest in determining risk of fall in stroke patients(2019) Sahin, Ilknur Ezgi; Guclu-Gunduz, Arzu; Yazici, Gokhan; Ozkul, Cagla; Volkan-Yazici, Melek; Nazliel, Bijen; Tekindal, Mustafa Agah; 0000-0002-4060-7048; 30814369BACKGROUND: Balance disorders cause disability in stroke and increase risk of falls. The Balance Evaluation Systems Test (BESTest), examines balance, determines parameters causing balance disorders, provides information on risk factors for falls. OBJECTIVE: To investigate the sensitivity and specificity of the BESTest in determining the risk of fall in stroke patients. METHODS: Fifty patients with chronic stroke were included in the study. Balance was assessed using BESTest, Berg Balance Scale (BBS), Activity Specific Balance Confidence scale (ABC) and Biodex-BioSway Balance System. To examine the content validity of BESTest, the relationship between BESTest and other balance assessment methods was examined. The internal consistency reliability of BESTest was evaluated by Cronbach's alpha coefficient. Analysis of receiver operating characteristics (ROC) was performed to determine cut-off point, sensitivity and specificity. RESULTS: BESTest, BBS, ABC and Biodex-BioSway Balance System results of faller stroke patients were worse than that of non-faller (p < 0.05). Internal consistency of BESTest was found to be Cronbach's alpha = 0.960. The BESTest value of area under the curve (AUC) was 0.844, with a cut-off point of 69.44%, a sensitivity of 75% and a specificity of 84.6% (p < 0.01). CONCLUSION: BESTest is reliable and valid with high sensitivity and specificity in determining the risk of fall in stroke patients.Item Evaluation of Moro reflex with an objective method in late preterm and term infants(2019) Ince, Deniz Anuk; Ecevit, Ayse; Yildiz, Metin; Tugcu, Ali Ulas; Ceran, Burak; Tekindal, Mustafa Agah; Turan, Ozden; Tarcan, Aylin; 0000-0002-4369-2110; 0000-0002-2554-6953; 30660088; I-6746-2016Item Assessment of Subclinical Atherosclerosis in Vitamin D Deficiency(2019) Aydin, Elcin; Altin, Cihan; Soylev, Gozde Ozcan; Tekindal, Mustafa Agah; Agildere, Muhtesem; 30300321; AAB-5802-2020Purpose Patients with vitamin D deficiency (VDD) have potential to have increased cardiovascular morbidity and mortality. In this study, we aimed to discover the findings of early atherosclerosis in patients with VDD by measuring carotid intima-media thickness (CIMT) and epicardial fat thickness (EFT). Materials and Methods The study population includes 52 patients with VDD (n = 30 [57% female], mean +/- SD age 54.28 +/- 8.77 years, mean +/- SD serum 25-hydroxyvitamin D (25 [OH] D) 11 +/- 2.4 ng/mL) and 82 participants for control group (n = 52 [63.4% female], mean +/- SD age 56.40 +/- 7.90 years, mean +/- SD serum (25 [OH] D) 53 +/- 4.2 ng/mL) who have no cardiovascular disease. Carotid intima-media thickness was assessed by using ultrasonography, and EFT was measured on the free wall of the right ventricle at end diastole from the parasternal long-axis views by standard transthoracic 2-dimensional echocardiography. Results Both CIMT and EFT were significantly higher in patients with VDD compared with controls (0.75 +/- 0.16 mm vs 0.68 +/- 0.21 mm, P < 0.05, and 0.66 +/- 0.15 cm vs 0.56 +/- 0.15 cm, P < 0.001). Conclusions Patients with VDD seem to have increased CIMT and EFT, which are predictors of atherosclerotic process. Further studies are needed to confirm these results.
