Item Efficacy of Ultrasound Versus Short Wave Diathermy in the Treatment of Chronic Low Back Pain in Patients with Lumbar Disk Herniation: A Prospective Randomized Control Study(2023) Ozen, Selin; Guzel, Sukran; Senlikci, Huma Boluk; Cosar, Sacide Nur Saracgil; Selcuk, Ebru Selin; 0000-0002-7290-8558; 0000-0001-8306-463X; 37986090; ABC-1305-2020; AAF-1085-2021Background Lumbar disk herniation (LDH) is a cause of chronic low back pain (CLBP) treated using physical therapy (PT), including exercise and physical modalities such as ultrasound (US) and short wave diathermy (SWD). Despite the use of US and SWD, there is inconclusive evidence on their efficacy. The aim of this study was to investigate the efficacy of US and SWD in the treatment of CLBP in patients with LDH.Method A prospective randomized control clinical study. Individuals with radicular CLBP and LDH on magnetic resonance imaging, presenting to the Physical and Rehabilitation Medicine Department were randomized into 3 treatment groups. All participants received 10 sessions of hotpack, transcutaneous nerve stimulation (TENS) and therapeutic exercises. In addition, Group 1 received 10 sessions of therapeutic US (1 MHz, 1.5W/cm2, 10 min), Group 2 SWD (27.12 MHz, wavelength 11.06 m, induction technique, 20 min) to the lower back. Group 3 (control group) received hotpack, TENS and therapeutic exercises alone. Visual analogue scale (VAS) for LBP, Modified Oswestry Disability Index (MODI) and Short Form 36 (SF-36) were evaluated pre and post treatment and at one and three months follow up.Results In all groups, VAS for LBP and MODI improved with treatment and at the one and three month follow up (p < 0.001). In Groups 1 and 2, MODI scores continued to reduce at 1 and 3 months (p < 0.001 and p = 0.012 respectively). SF-36 physical, social function and pain parameters reduced in all groups (p < 0.05). Role limitation due to physical and emotional problems, emotional well-being, vitality and mental health improved in Groups 1 and 2 (p < 0.05).Conclusions Deep heating agents can be used as part of the physical therapy for CLBP in those with LDH with positive mid-term effects.Trial registrationNCT03835182, 02/04/2019.Item Prevalence of Persistent Median Artery in Carpal Tunnel Syndrome: Sonographic Assessment(2016) Altinkaya, Naime; Leblebici, Berrin; https://orcid.org/0000-0003-1348-8167; https://orcid.org/0000-0002-6241-268X; 26324380; AAM-5169-2021; AAM-3220-2021This study investigated the frequency of persistent median artery (PMA) in patients with carpal tunnel syndrome (CTS) and controls. A total of 84 CTS patient wrists, and 136 wrists of control subjects without CTS, were examined on ultrasonography (US) and color Doppler US (CDUS), and by electrophysiological evaluations. The frequency of PMA in CTS was evaluated. Of 84 CTS patient wrists, 2 (2.4 %) had a PMA (both on the right side). Of 136 control wrists, 12 (9 %) had a PMA, which was unilateral in eight (three right and five left), and bilateral in two, cases. There was no significant difference between the CTS patient and control groups with respect to the frequency of PMA (P > 0.05). There was no significant difference between the CTS patient and control groups in the frequency of PMA. We suggest that an ipsilateral PMA does not increase the risk of CTS.Item Ultrasonographic and Electrophysiological Evaluation of the Ulnar Nerve in Patients Diagnosed With Carpal Tunnel Syndrome(2016) Ozlece, Hatice Kose; Huseyinoglu, Nergiz; Gok, Mustafa; Ilik, Faik; 27760070Purpose: In this study, we evaluated the ulnar nerve of patients diagnosed with carpal tunnel syndrome (CTS) using electrophysiology and ultrasonography. Methods: The study included 86 patients (136 hands) and 39 controls (78 hands) with normal electrophysiological assessment. According to Bland's classification, patients were divided into group 1 (grades 1-3 CTS) or group 2 (grades 4-6 CTS). The ulnar nerve was evaluated at the wrist using nerve conduction studies and ultrasonography. Results: The sensory velocity was slower in group 2 than in group 1 (P < 0.001), slower in group 2 than in controls (P < 0.001), and slower in group 1 than in controls (P < 0.005). Although the ultrasonography results showed a reduction in the ulnar nerve cross-sectional area in group 1 compared with controls, the difference was not statistically significant. However, the reduction was significant in group 2 compared with group 1 and controls (P < 0.001). Conclusions: Based on our study results, the ulnar nerve is affected electrophysiologically and morphologically in patients with CTS, especially those with advanced-stage CTS.Item Is There A Correlation Between the Severity of Idiopathic Granulomatous Mastitis and Pre-Treatment Shear-Wave Elastography Findings? Original Research(2018) Aslan, Hulya; Arer, Ilker Murat; Pourbagher, Aysin; Ozen, Merve; 0000-0002-7138-246X; 30665211; AAK-9104-2021; HCH-8774-2022AIM: The aim of this study was to analyze the correlation between the severity of idiopathic Garulomatous Mastitis (IGM) and the pre-treatment Shear-Wave Elastography (SWE) findings. MATERIAL AND METHODS: A total of 39 patients diagnosed with granulomatous mastitis were included in the study between the dates of December 2014 and February 2017. The patients were divided into two groups. Group 1 was treated using a conservative protocol and steroids. Group 2 was treated surgically. Pre-treatment SWE findings of both groups were compared. RESULTS: The mean ages of the patients in group 1 and 2 were 38.44 +/- 9.6 and 3605 +/- 7.44 years, respectively. There were not any significant differences between the groups with regard to frequency of BI-BADS categories and Virtual touch tissue imaging (VTI) patterns. The mean Shear-Wave Spead (SWS) were 1.98 +/- 1.02 m/sec and 2.82 +/- 1.66 m/sec in group 1 and 2 respectively. The difference was not significant (p >= 0.05). The BI-RADS categories and VTI patterns did not show significant difference when the recurrent and non-recurrent patients were compared. CONCLUSION: There may not be a correlation with the pre-treatment SWE findings and severity of the IGM.Item Efficacy of the Sonoelastography Method for Diagnosis of Fibrosis in Renal Transplant Patients(2022) Soudmand, Arash; Ozturk, Funda Ulu; Uslu, Nihal; Haberal, Nihan; Boyvat, Fatih; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0002-3462-7632; 29993356; AAJ-8097-2021Objectives: Although biopsy is the most important method for diagnosing the cause of renal allograft dysfunction, sonoelastography, a new ultrasonography method, can be used to distinguish between the soft or hard nature of lesions. In this study, our aim was to investigate whether sonoelastography could diagnose fibrosis in renal transplant patients. Materials and Methods: In this prospective study, we included patients over 18 years old who were recommended for clinical biopsy. Sonoelastographic evaluation was made by conducting acoustic radiation force impulse measurements for each patient after they were admitted to the clinic for biopsy. Measurements were performed just before the biopsy procedure. All results were examined by 2 experienced radiologists using the Siemens S3000 Ultrasound Machine (Erlangen, Germany). Comparisons of ultrasonographic values with biopsy results were made with SPSS software (SPSS: An IBM Company, version 20, IBM Corporation, Armonk, NY, USA). Results: Of the 65 patients included in this study, pathology showed acute T-cell-mediated rejection in 37 patients. There was a significant correlation between the pathologic Banff scores and the sonographic acoustic radiation force impulse values (P = .002), where the degree of Banff increased as the mean acoustic radiation force impulse values elevated. A rise in mean impulse values correlated with increased degree of interstitial fibrosis in renal allografts. Renal parenchymal echogenicity of patients significantly differed by sex (P = .009), with an average renal echogenicity of grade 1 in women and grade 0 in men. Also, a statistically significant difference was found between age of the renal transplant recipient and resistive index values. Conclusions: Our study showed a significant correlation between Banff degree and the acoustic radiation force impulse values of renal transplant patients. In addition to biopsy, sonoelastography can be beneficial for the diagnosis of fibrosis in renal transplant patients.Item Liver Stiffness Measurements Using Acoustic Radiation Force Impulse in Recipients of Living-Donor and Deceased-Donor Orthotopic Liver Transplant(2021) Haberal, Kemal Murat; Turnaoglu, Hale; Ozdemir, Adnan; Uslu, Nihal; Reyhan, Asuman Nihan Haberal; Moray, Gokhan; Haberal, Mehmet; 0000-0002-8211-4065; 0000-0002-3462-7632; 28836931; R-9398-2019; AAJ-8097-2021Objectives: The aim of this study was to evaluate the diagnostic efficiency of the acoustic radiation force impulse (Siemens Medical Solutions, Erlangen, Germany) elastography in assessment of fibrosis in orthotopic liver transplant patients. Materials and Methods: We enrolled 28 orthotopic liver transplant patients (5 deceased and 23 living donors), whose biopsy decision had been prospectively given clinically. Ten acoustic radiation force impulse elastographic measurements were applied before the biopsy or within 3 days after the biopsy by 2 radiologists. After the core tissue needle biopsy, specimens of all patients were analyzed according to the modified Ishak scoring system. Measurements of acoustic radiation force impulse elastography and pathology specimen results were compared. Results: From 28 biopsies, fibrosis scores of 4 biopsies were evaluated as F0 (14.3%), 16 as F1 (57.1%), 4 as F2 (14.3%), and 4 as F3 (14.3%). Mean results of acoustic radiation force impulse measurements were calculated as 1.4 +/- 0.07 in F0, 1.74 +/- 0.57 in F1, 2.19 +/- 0.7 in F2, and 2.18 +/- 0.35 in F3. There were no significant correlations of mean acoustic radiation force impulse values between the F0 versus F1 (P =.956) and F0 versus F2 stages (P =.234). A statistically significant correlation of mean acoustic radiation force impulse values was found between the F0 and F3 fibrosis stages (P =.046). Conclusions: Acoustic radiation force impulse imaging is a promising screening test for detecting significant liver fibrosis (>= F3 in modified Ishak) in living- donor or deceased-donor orthotopic liver transplant recipients.Item EVALUATION OF EPICARDIAL FAT AND CAROTID AND FEMORAL INTIMA-MEDIA THICKNESSES IN GERIATRIC PATIENTS WITH END-STAGE RENAL DISEASE(2020) Gunesli, Aylin; Yilmaz, Mustafa; Yalcin, Cigdem; Tekkarismaz, Nihan; Alkan, Ozlem; 0000-0002-2557-9579; 0000-0001-5483-8253; 0000-0001-7631-7395; S-6973-2016; AAM-4284-2021; AAD-9088-2021Introduction: Although atherosclerotic cardiovascular diseases and cardiovascular risks are known to increase in patients with end-stage renal disease, it is not clear whether these risks increase in the geriatric patient population as well. This study aims to evaluate these risks in geriatric patients with end-stage renal disease by evaluating epicardial fat and carotid and femoral intima-media thicknesses, known as markers, for subclinical atherosclerosis and cardiovascular risks. Materials and Methods: This cross-sectional study included 52 patients who started to receive chronic hemodialysis treatment after the age of 65 years (mean age 73.92 +/- 5.63) years with end-stage renal failure and 51 healthy volunteers (mean age: 74.49 +/- 4.63 years). Epicardial fat and carotid and femoral intima-media thicknesses were measured and compared between these groups. Results: Carotid intima-media and epicardial fat thicknesses were significantly higher in the patient group than in the control group (0.91 +/- 0.08 vs. 0.71 +/- 0.1 mm, p<0.001 and 0.84 +/- 0.17 vs. 0.75 +/- 0.17 cm, p=0.01, respectively). However, no significant difference was observed in femoral intima-media thickness between the two groups (0.58 +/- 0.07 vs. 0.56 +/- 0.97 mm, p=0.266). Correlation analysis revealed a significant positive correlation between the duration of dialysis and epicardial fat and carotid intima-media thicknesses (r=0.611, p<0.001 and r=0.337, p=0.015, respectively). Furthermore, regression analysis revealed a significant relationship between the duration of dialysis and carotid intima-media thickness (beta=0.657, p=0.001). Conclusion: Epicardial fat and carotid intima-media thicknesses increase in geriatric patients with end-stage renal disease but with no significant changes in femoral intima-media thickness, indirectly suggesting that subclinical atherosclerosis and cardiovascular risks are increased in these patients.Item Predictive values of maternal serum PAPP-A level, uterine artery Doppler velocimetry, and fetal biometric measurements for poor pregnancy and poor neonatal outcomes in pregnant women(2016) Balci, Serdar; 0000-0002-1782-7325; 27651722; AAJ-1097-2021Objective: To determine predictive values of maternal serum PAPP-A (msPAPP-A) levels, uterine artery Doppler velocimetry, and fetal biometric measurements (FBMs) for poor pregnancy and poor neonatal outcomes. Material and Methods: This prospective cohort study was conducted on singleton pregnancies followed until delivery. Pregnancy and neonatal outcomes were evaluated with respect to the msPAPP-A level at the 11th-14th weeks, uterine artery Doppler velocimetry at the 15th-18th weeks, and FBMs at the 20th-24th and 28th-32nd weeks of pregnancy. Results: One hundred fifty-eight women constituted the study group; 17 (10.75%) of them had at least one poor pregnancy outcome. The cut-off point of 0.72 multiple of the median (MoM) for the PAPP-A level achieved a sensitivity of 82.4% and a specificity of 29.8% for poor pregnancy outcomes. The mean birth weight was significantly lower in the subgroup with a higher mean pulsatility index of uterine arteries (UAPImean >= 1.19) (p=0.025) as well as in the subgroup with a higher mean resistance index of uterine arteries (UARImean >= 0.62) (p=0.013). When the subgroup of pregnant women under the risk of early-onset IUGR according to FBMs was compared to the low-risk group, statistically significant differences were seen in terms of pregnancy outcomes (p=0.045) and birth weight (p=0.011). Conclusion: Maternal serum PAPP-A level and FBMs could be used for predicting pregnancy outcomes, while uterine artery Doppler velocimetry and FBMs could be used for predicting neonatal outcomes, specifically the birth weight.Item Treatment with ultrasound guided percutaneous cholecystostomy in acute cholecystitis: 10-year a single-center experience(2017) Ozyer, Umut; Yildirim, Muge; Yildirim, Utku Mahir; 0000-0002-4300-009X; AAK-9071-2021; AAK-9071-2021Purpose: Evaluating the technical success, clinical outcomes and safety of ultrasound-guided percutaneous cholecystostomy (PC) in patients with acute cholecystitis. Material and Methods: Medical records of patients diagnosed as acute cholecystitis and treated with PC from year 2000 to 2011 were retrospectively examined. ASA scores, leukocyte counts, gall stone presence, bile cultures, additional interventions, interval surgery, procedure-related complications and mortality were reviewed. Results: PC catheters were placed in 127 patients (72 male, 55 female) aged from 31 to 100 years. Technical success of the procedure was 100%. Clinical success was obtained in 86% of the patients. No procedure related mortality or early major complications were observed. Minor complication rate was 7% (9/127) and late major complication rate was 3% (4/127). Thirty day in-hospital mortality rate was 8% (10/127). Six patients died after interval cholecystectomy and 4 patients died before the operation. PC served as a definitive treatment in 74% (17/23) of the patients with acalculous cholecystitis. Fifty-eight percent (31/53) of the patients with acute calculous cholecystitis were treated only with percutaneous cholecystostomy and only 10% (3/31) had recurrent cholecystitis in follow up. Conclusion: PC can be preferred over primary cholecystectomy in acute cholecystitis patients. The procedure has high technical success, high clinical response and low complication rates. It can also serve as a definitive treatment option in patients with high surgical risk.
