Background: We aimed to assess the accuracy of artificial intelligence (AI) based real-time anatomy identification for ultrasound-guided peripheral nerve and plane block in eight regions in this prospective observational study.
Methods: After obtaining ethics committee approval and written informed consent from 40 healthy volunteers (20 men and 20 women, between 18 and 72 years old), an ultrasound device installed with AI software (Nerveblox, SmartAlfa, Turkey) were used to scan regions of the cervical plexus, brachial plexus, pectoralis (PECS), rectus sheet, femoralis, canalis adductorius, popliteal, and ESP by three anesthesiology trainees. During scanning by a trainee, once software indicates 100 % scan success of associated anatomic landmarks, both raw and labeled ultrasound images were saved, assessed, and validated using a 6-point scale between 0 and 5 by two expert validators.
Rationale And Objectives: To compare the efficacy of two thermal ablation techniques (radiofrequency vs microwave ablation) in the treatment of benign thyroid nodules.
Materials And Methods: A total of 80 patients with 80 nodules underwent thermal ablation of thyroid nodules with either radiofrequency ablation (RFA) (23 females and 14 males; mean age 41 ± 9years) or microwave ablation (MWA) (28 females and 15 males; mean age 45 ± 11years). Ultrasound assessments were made at the 1st, 3rd, 6th, and 12th months after the ablation procedure.
We aimed to assess the accuracy of an artificial intelligence (AI)-based real-time anatomy identification software specifically developed to ease image interpretation intended for ultrasound-guided peripheral nerve block (UGPNB). Forty healthy participants (20 women, 20 men) were enrolled to perform interscalene, supraclavicular, infraclavicular, and transversus abdominis plane (TAP) blocks under ultrasound guidance using AI software by anesthesiology trainees. During block practice by a trainee, once the software indicates 100% scan success of each block associated anatomic landmarks, both raw and labeled ultrasound images were saved, assessed, and validated using a 5-point scale by expert validators.

Purpose: To compare the degree of thickening and nerve elasticity of brachial plexus (BP) nerve roots and evaluate the usefulness of sonoelastography in patients with clinically diagnosed MS without brachial plexopathy.
Purpose: In this study, we investigated the diagnostic efficacy of 2D-Shear Wave Elastography (2D-SWE) in detecting stages of liver fibrosis and determining the disease-specific cut-off values in patients with chronic hepatitis B and C infection, using histopathological analysis as the reference method.
Method: Our study included 103 consecutive adult patients with chronic hepatitis B and C infection (CHB and CHC) who had liver biopsy within three months of elastography examination. A real-time 2D-SWE was performed using the LOGIQ E9 system (GE Medical Systems, Wisconsin, USA).
Purpose: The first aim of this study was to evaluate changes in the stiffness of the medial gastrocnemius muscle (GM) after a botulinum toxin A (BoNT-A) injection in children with cerebral palsy (CP) using shear wave elastography (SWE). We also wanted to investigate the usability of SWE for evaluating spasticity in a clinical setting. The second aim of this study was to show how treatment of the gastrocnemius muscle spasticity caused a change in the elasticity of the anterior tibial (TA) muscle.

Background: Studies in mice have suggested that sarcopenic animals may have atrophic diaphragmatic muscles; however, to date, no clinical studies are available.
Aims: To investigate whether the diaphragmatic thickness is affected in older patients with sarcopenia and if this is associated with impaired respiratory functions.

Data including primary indication for gastrostomy, sex, concomitant disease and the requirement for gastroesophageal reflux disease (GERD) were all recorded.
Purpose: To investigate the effects of combined orbital bone and fat decompression on intraocular pressure (IOP) and superior ophthalmic vein blood flow velocity (SOV-BFV), and their association with the clinical features of Graves orbitopathy (GO).
Methods: During the 2002-2008 period, 72 eyes of 36 GO cases demonstrating moderate to severe orbitopathy were evaluated according to their clinical features as: cases with or without dysthyroid optic neuropathy (DON), and underwent orbital decompression. A control group comprised 40 eyes of 20 healthy subjects.
Objectives: Children with obesity have a high cardiovascular risk and an impaired oxidant-antioxidant status, which may lead to endothelial dysfunction and increased carotid intima media thickness (IMT) even in childhood. The aim of this study was to investigate the circulating oxidized low-density lipoprotein (LDL) concentrations and the IMT of carotid arteries in prepubertal obese children, and also to search for its possible association with carotid atherosclerosis.
Methods: Twenty-seven prepubertal obese children (age, 7.
The aim of this study was to examine the intima-media thickness (IMT) of carotid arteries and endothelial function parameters such as plasma asymmetric dimethylarginine (ADMA) and homocysteine levels in hypercholesterolemic children and to investigate the relations of these parameters with hypercholesterolemia. Fifty-seven hypercholesterolemic and 37 healthy children were included in the study. Hypercholesterolemia was defined as 155 mg/dl and above for low-density lipoprotein (LDL)-cholesterol.

Piriformis syndrome is a rare cause of hip and foot pain which may be due to sciatic nerve irritation because of anatomic abnormalities of sciatic nerve and piriformis muscle or herniated disc, facet syndrome, trochanteric bursit, sacroiliac joint dysfunction, endometriosis and other conditions where sciatic nerve is irritated. There has been no reflex sympathetic dystrophy (RSD) case presented due to piriformis syndrome before. A sixty-two-year-old female patient had right foot and hip pain (VNS: 8), redness and swelling in the foot since 15 days.

Background: The deep inferior epigastric artery perforator (DIEAP) flap is a technically demanding procedure and the dissection is directly influenced by the size of the perforator vessels. There is a common belief that the size of the superficial inferior epigastric vein (SIEV) is inversely proportional to the perforators from the deep inferior epigastric system. To investigate the validity of this hypothesis, we evaluated and compared the diameters of the SIEV and deep inferior epigastric perforator vessels (DIEP-A and DIEP-V).

Hyperuricemia (HU) is a well recognized risk factor for cardiovascular diseases. The independence of this association from other confounding factors has remained controversial.
