Item Effect Of Meal Intake For Evaluating Hepatic Artery By Doppler Ultrasonography In Liver Transplants: Does Fasting Matter For Screening Hepatic Artery Due To Hemodynamic Changes In Splanchnic Circulation?(2022) Ozturk, Funda Ulu; Tezcan, Sehnaz; Soy, Ebru Hatice Ayvazoglu; Uslu, Nihal; Haberal, Mehmet; https://orcid.org/0000-0003-2782-2824; https://orcid.org/0000-0001-7204-3008; https://orcid.org/0000-0002-0993-9917; https://orcid.org/0000-0002-3462-7632; 35419884; AAC-5566-2019; AAJ-8097-2021Purpose The aim of this study is to assess the utility of fasting on Doppler ultrasonography findings of hepatic artery in liver transplants. Methods Liver transplant patients without vascular abnormalities were prospectively evaluated between December 2017 and January 2020. Doppler sonography was used to describe hemodynamic changes in response to a standard meal. The diameter, peak systolic velocity, blood flow, resistive index (RI) of the main hepatic artery and portal vein peak velocity were measured. Results The mean hepatic arterial diameter of 44 patients was higher in the fasting group (4.5 mm) than in the postprandial group (3.3 mm) (p < .05). The mean hepatic arterial blood flow decreased (from .276 to .127 L/min) and hepatic arterial RI increased (from .66 to .71) following meal ingestion (p < .05). Hepatic arterial velocity was significantly lower and portal venous velocity was higher after oral intake. Conclusion Meal ingestion has an important effect on hepatic artery Doppler features in liver transplants. Therefore, Doppler ultrasound evaluation should be considered after appropriate fasting due to postprandial responses of liver transplant.Item Ultrasonographic evaluation of Achilles tendon: Is there any difference between ankylosing spondylitis, non-radiographic axial spondyloarthropathy and controls?(2020) Vahidfar, Shahla; Sunar, Ismihan; Ataman, Sebnem; Yilmaz, Gurkan; Azarabadi, Javid M.; Bolukbasi, Ayse; 31985181Purpose: The aim is to evaluate Achilles tendon enthesopathy with ultrasound (US) in ankylosing spondylitis (AS) and non-radiographic axial SpA (nr-axSpA) patients and controls, and compare these groups in terms of associations between disease activity parameters and ultrasonographic Achilles enthesitis signs. Methods: A total of 24 AS and 20 nr-axSpA patients fulfilling the Assessment in Spondyloarthritis International Working Group criteria for axSpA and 30 controls were enrolled. Demographic characteristics, erythrocyte sedimentation rate, C-reactive protein (CRP), human leukocyte antigen (HLA)-B27, Bath AS Disease Activity Index, Bath AS Functional Index, Bath AS Metrology Index, Maastricht AS Enthesitis Score (MASES), AS Disease Activity Score-CRP, modified Stoke AS Spine Score (m-SASSS) scores and ultrasonographic findings were noted. Results: HLA-B27 positivity, extra-articular and peripheral involvement, disease activity, functional status, mean m-SASSS, ultrasonographic gray scale (GS) and total scores were similar between AS and nr-axSpA groups. In GS, tendon echotexture scores were significantly different across all groups (0.812 +/- 0.384 in AS, 0.575 +/- 0.466 in nr-axSpA, 0.017 +/- 0.091 in controls; P < .001). Entheseal calcification scores were similar in AS and nr-axSpA patients, and higher than controls (P = .001). Bone profile scores were similar in patients with AS and nr-axSpA, and higher than controls (P = .010). When the correlations between US findings and disease activity and functional status were considered, power Doppler US (PDUS) and MASES total scores were positively correlated in the AS group (P = .045; r = .41). Conclusion: AS and nr-axSpA patients were found to be similar in various clinical, functional, and US findings indicating that these 2 entities are different phenotypic reflections of the same disease spectrum. The positive correlation between PDUS and MASES scores in AS patients substantiate the performance of MASES in evaluation of entheseal activity.Item Ultrasound-guided versus blind subacromial corticosteroid and local anesthetic injection in the treatment of subacromial impingement syndrome: A randomized study of efficacy(2020) Akbari, Najibeh; Ozen, Selin; Senlikci, Huma Boluk; Haberal, Murat; Cetin, Nuri; 0000-0002-9950-8917; 0000-0002-7290-8558; 0000-0002-8211-4065; 32160504; AAK-4129-2021; ABC-1305-2020; R-9398-2019Objectives: This study aims to compare the effects of ultrasound (US)-guided and blind subacromial corticosteroid and local anesthetic (LA) injection in the treatment of subacromial impingement syndrome (SIS) on shoulder pain, range of motion (ROM), and functionality. Patients and methods: The prospective study was conducted between 01 February 2017 and 31 May 2017. A total of 29 patients with clinical findings and magnetic resonance imaging (MRI) consistent with SIS were randomized into two groups: 14 patients received US-guided subacromial corticosteroid and LA injection and 15 patients received a blind subacromial corticosteroid and LA injection. Patients were evaluated before and one month after treatment. One patient was lost to follow up. The primary outcome measure was a visual analog scale (VAS) for shoulder pain. Secondary outcomes were active shoulder ROM in flexion and abduction, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and the modified Constant-Murley Score (CMS). Results: Twenty eight patients (11 males, 17 females; mean age 39.5 in the US guided group and 42.5 in the blind group: range 20 to 64 years in both groups) completed the study. There was a significant improvement in VAS for shoulder pain, active ROM, DASH questionnaire score and modified CMS in both groups four weeks after treatment (p<0.05). There was no between-group difference in VAS, ROM or DASH questionnaire scores. Following treatment, the modified CMS in the US-guided injection group was higher than in the blind injection group (p=0.02). However, when the mean change in modified CMS in the US-guided injection group was compared to that of the blind injection group, the difference was insignificant (p=0.23). Conclusion: Both US-guided and blind subacromial steroid injection improve shoulder pain, ROM, and functionality in SIS; one treatment option was not found to be superior to the other. Therefore, blind injection can be performed in clinical settings where US is not available. Equally, blind injection can also be performed in patients who have a definite diagnosis of SIS based on clinical and MRI findings.Item Single- or double-layer uterine closure techniques following cesarean: A randomized trial(2020) Yilmaz Baran, Safak; Kalayci, Hakan; Dogan Durdag, Gulsen; Yetkinel, Selcuk; Alemdaroglu, Songul; Cok, Tayfun; Bulgan Kilicdag, Esra; 0000-0002-5064-5267; 0000-0002-2165-9168; 0000-0003-4335-6659; 0000-0002-0942-9108; 0000-0002-7854-2921; 0000-0001-5874-7324; 33029804; AAI-9594-2021; AAL-1530-2021; AAI-8400-2021; AAK-8872-2021; A-8208-2008; ABF-6439-2020Introduction Cesarean deliveries are commonly performed throughout the world. Although the uterine closure technique following this procedure may influence how the uterine scar heals, there is insufficient evidence for choosing the appropriate technique and so preventing long-term negative consequences. This prospective, randomized study examined the effects of single- and double-layer uterine closure techniques on uterine scar healing following cesarean delivery. Material and methods This study assessed a total of 282 women aged 18-45 years who were in gestational weeks 24-41 of singleton pregnancies. None had previously undergone uterine surgeries. These participants completed their first cesarean deliveries at the time of study and were randomized into the following two treatment groups: single-layer closure with locking and double-layer closure with locking in the first layer, but not in the second layer (NCT03629028). However, the decidua was not included for treatment in either group. Participants were evaluated at 6-9 months after cesarean section by saline infusion sonohysterography to assess cesarean delivery scar defects. These procedures were conducted by experienced sonographers who were not aware of the uterine closure technique. Results Of the 225 final participants, 109 received the single-layer closure technique, whereas 116 received the double-layer technique. The niche rates were 37% (n = 40) for the single-layer group and 45.7% (n = 53) for the double-layer group (P = .22, relative risk 1.4, 95% CI = 0.8-4.4). Conclusions The single- and double-layer closure techniques did not produce different impacts on uterine scar niche development.Item The success rate and safety of internal jugular vein catheterization under ultrasound guidance in infants undergoing congenital heart surgery(2019) Altun, Dilek; Nurac, Salih Hakan; Toprak, Verda; Eti, Emine Zeynep; 32082823Background: In this study, we aimed to investigate the effect of central venous catheterization under ultrasound guidance on the success and complication rates in low-weight infants (under 5 kg) undergoing surgery due to congenital heart disease. Methods: A total of 70 infants (38 boys, 32 girls; mean age of patients <1 month was 16.4 +/- 9.5 days [n=20; 28.6%]; 1-7.5 months was 126.3 +/- 47.8 [n=50; 71.4%]) who underwent ultrasound-guided internal jugular venous catheterization between October 2014 and October 2015 were retrospectively analyzed. All catheterizations were done under the guidance of ultrasound by two skilled anesthesiologists. Data including demographic characteristics of the patients, procedural success rate, catheter access time, number of attempts, and complications were recorded. Results: The overall success rate of the procedure was 92.8% (n=65). In 82% of the patients (n=53), the insertion was successful at the first attempt. The mean catheter access time (time from the first puncture to the catheter insertion) was 214 +/- 0.48 sec. Complications were seen in five patients (7.14%), and the body weight of these patients was less than 2,500 g There was no arterial puncture in any patients. One patient (1.42%) developed pneumothorax and four patients (5.7%) developed hematoma due to repeated attempts. Conclusion: Our study results suggest that ultrasound-guided central venous cannulation is a safe and effective technique in pediatric population weighing less than 5 kg undergoing congenital heart surgery.Item Efficacy of ultrasound-guided bilateral erector spinae plane block in pediatric laparoscopic cholecystectomy: Case series(2019) Karaca, Omer; Pinar, Huseyin Ulas; 0000-0003-0473-6763; 31741347; Q-2420-2015Postoperative opioid administration can cause various side effects, such as drowsiness, respiratory distress, postoperative nausea, and vomiting. The use of non-opioid medications as part of a multimodal analgesia method has been increasingly suggested in the management of acute postsurgical pain. Erector spinae plane block (ESPB), which is a regional anesthesia technique, blocks both visceral and somatic nerve fibers.Though it is infrequently used in young patients, presently described is a series of cases in which ESPB was successfully used in the performance of pediatric laparoscopic cholecystectomy. Ultrasound-guided bilateral ESPB was performed on 4 patients who underwent a laparoscopic cholecystectomy. An injection of 0.25% bupivacaine was administered into the interfascial area on each side in the pre-incisional period after the anesthesia induction (total anesthetic: 2.5 mg/kg). Postoperative pain control was planned at 10 mg/kg intravenous paracetamol every 8 hours. Numeric rating scale pain scores were less than 3 points in the post-anesthetic care unit, and at 1, 2, 4, 8, 12, and 24 hours. No rescue analgesic (1 mg/kg tramadol) was needed. None of the typical complications, such as drowsiness or nausea, were observed and no block-related complications were recorded. Bilateral ESPB that is a part of multimodal analgesia regimen can provide effective analgesia for pediatric laparoscopic cholecystectomy patients in the first 24 hours postoperatively.Item Ultrasound-Guided versus Conventional Caudal Block in Children: A Prospective Randomized Study(2019) Karaca, Omer; Pinar, Huseyin Ulas; Gokmen, Zeynel; Dogan, Rafi; 0000-0003-0473-6763; 0000-0003-1933-2075; 30602192; Q-2420-2015; AAU-6923-2020Background Injection to the accurate area without any complications is the main factor for the efficiencies of caudal block. The aim of this study was to compare success and the complications of conventional and ultrasound method for caudal block in children. Materials and Methods Two-hundred sixty-six American Society of Anesthesiologists (ASA) category 1 children aged between 6 months and 6 years undergoing hypospadias, circumcision, or both surgeries were randomly allocated two groups (Group C or Group H, n =133). About 0.25% bupivacaine with 1/200000 adrenaline (total volume: 0.5 mL/kg) was injected after the needle was inserted into the sacral canal in Group C, or right after the needle pierced the sacrococcygeal ligament under longitudinal ultrasound view in Group H. Success rate of block, block performing time, number of needle puncture, success at first puncture, complication rate, age and weight of the patients encountering these complications were recorded. Results The success rate of block was similar between two groups (94.7% in Group C vs 96.2% in Group U, p >0.05). Success at first puncture was higher in Group U than in Group C (90.2 vs 66.2%, respectively; p <0.001). Number of needle puncture, blood aspiration, subcutaneous bulging, and bone contact was higher in Group C but none in Group U ( p <0.001) and these complications were occurred in children weighing<16kg and less younger than 6 years old. Conclusion We observed that the complications were not encountered, number of needle puncture was lesser, and the success rate of first puncture was higher under ultrasound with longitudinal view.Item Evaluation of tularaemia courses: a multicentre study from Turkey(2014) Turan, H.; 24975504In this multicentre study, which is the largest case series ever reported, we aimed to describe the features of tularaemia to provide detailed information. We retrospectively included 1034 patients from 41 medical centres. Before the definite diagnosis of tularaemia, tonsillitis (n=653, 63%) and/or pharyngitis (n=146, 14%) were the most frequent preliminary diagnoses. The most frequent clinical presentations were oropharyngeal (n=832, 85.3%), glandular (n=136, 13.1%) and oculoglandular (n=105, 10.1%) forms. In 987 patients (95.5%), the lymph nodes were reported to be enlarged, most frequently at the cervical chain jugular (n=599, 58%), submandibular (n=401, 39%), and periauricular (n=55, 5%). Ultrasound imaging showed hyperechoic and hypoechoic patterns (59% and 25%, respectively). Granulomatous inflammation was the most frequent histological finding (56%). The patients were previously given antibiotics for 1176 episodes, mostly with -lactam/-lactamase inhibitors (n=793, 76%). Antituberculosis medications were provided in seven (2%) cases. The patients were given rational antibiotics for tularaemia after the start of symptoms, with a mean of 26.8 +/- 37.5days. Treatment failure was considered to have occurred in 495 patients (48%). The most frequent reasons for failure were the production of suppuration in the lymph nodes after the start of treatment (n=426, 86.1%), the formation of new lymphadenomegalies under treatment (n=146, 29.5%), and persisting complaints despite 2weeks of treatment (n=77, 15.6%). Fine-needle aspiration was performed in 521 patients (50%) as the most frequent drainage method. In conclusion, tularaemia is a long-lasting but curable disease in this part of the world. However, the treatment strategy still needs optimization.
