Investigating the Role of Symptom Duration and Critical Shoulder Angle in Predicting Acromiohumeral Interval Reversibility in Patients With Massive Rotator Cuff Tears.

Background: Acromiohumeral interval (AHI) reversibility is used to evaluate whether superior humeral migration is fixed or flexible in patients with massive rotator cuff tears (MRCTs). AHI reversibility is measured as the difference in the AHI observed between standard and stress radiography. However, factors affecting AHI reversibility have not been studied in the existing literature.

The First Surgery Experienced Through Virtual Reality: A Knee Surgery Case Report.

The decision to undergo surgery and the significance of the operating theater environment are influenced by several factors, which vary from person to person. Negative perceptions of the operating room environment can influence the decision to undergo surgery and the process of treatment. Virtual reality (VR) technology offers the potential to alter individuals' environmental encounters through the provision of diverse environmental perceptions.

Comparative finite element analysis of four different internal fixation implants for Pauwels type III femoral neck fractures in various fracture angles in the sagittal plane.

Objectives: This study aimed to evaluate the performance of four different fixation techniques for Pauwels type III femoral neck fractures considering the fracture morphology in the sagittal plane.

Materials And Methods: We constructed three different fracture morphologies in the sagittal plane in Pauwels type III femoral neck fractures: posteriorly angled at 20°, neutral, and anteriorly angled at 20°. We set up four fixation devices, including three cannulated screws (3CS), a dynamic hip screw with an antirotational screw (DHS+CS), a proximal femoral locking plate (PFLP), and three cannulated screws with a medial buttress plate (3CS+MBP).

One of the rare reason of abdominal pain: abdominal wall endometriosis.

Objectives: Endometriosis is defined as the presence of normal endometrial mucosa abnormally implanted in locations other than the uterine cavity. It is most commonly located in the pelvis but it is also rarely observed in the gastrointestinal tract, lung, liver, kidneys, central nervous system and abdominal wall. Abdominal wall endometriosis (AWE) commonly occurs following a caesarean section or pelvic surgery.

The effect of the angle between fracture line and Kirschner wires on stability in supracondylar humerus fractures treated with Kirschner wire fixation: A finite element analysis.

Objectives: This study aims to investigate the effects of the angles created by the Kirschner wires (K-wires), which are applied in the percutaneous fixation of supracondylar humerus fractures with cross K-wire, with the fracture line on fracture stabilization.

Patients And Methods: The study was conducted on distal humerus fracture models. Medial and lateral K-wires were placed in the fracture models.

Is the fracture morphology in the sagittal plane important in determining the ideal placement of the lag screw in intertrochanteric femoral fractures?: Ideal lag screw placement in intertrochanteric fractures in the sagittal plane.

Objective: The aim of this study was to determine the ideal placement of the lag screw taking into account the fracture morphology in the sagittal plane.

Materials And Methods: Three different morphology of fractures were created on the sagittal plane in femur models obtained in 3D CT scanning: posteriorly angled (Type A), transverse (Type B) and anteriorly angled (Type C). The lag screw was applied in each of the three fracture morphology as neutral, anteverted and retroverted in the sagittal plane.

A new proximal femoral nail antirotation design: Is it effective in preventing varus collapse and cut-out?

Objectives: This study aims to compare the mechanical features of the existing proximal femoral nail antirotation (PFNA) system and the new PFNA system that we designed using three-dimensional (3D) finite element analysis.

Materials And Methods: This experimental study was conducted between 2019 and 2020. We constructed two femur models with Arbeitsgemeinschaft für Osteosynthesefragen (AO) type A1 fractures using 3D computed tomography scans.

Metatarsal Head Restoration With Tendon Autograft in Freiberg's Disease: A Case Report.

Freiberg's disease is a form of osteochondrosis of a metatarsal head that often affects the second metatarsophalangeal joint, and that affects females more often than males. Repetitive microtrauma, osteonecrosis, and stress overload are the main factors in its pathophysiology. Surgical intervention is indicated in advanced cases wherein nonoperative treatment has failed.

Management of Calvarial Tumors: A Retrospective Analysis and Literature Review.

Aim: Tumors of various organs that metastasize to bone do not neglect calvarium as a target. The aim of this study was to characterize the calvarial tumors.

Material And Methods: We retrospectively reviewed 45 consecutive patients operated for calvarial masses from January 2002 till May 2012 at our hospital.

Determination of the Relationship Between rs4986790 and rs4986791 Variants of TLR4 Gene and Lung Cancer.

Chronic inflammation triggers DNA damage and oncogenic mutations and causes tumor formation and tumor progression. One of the important components of the inflammatory response is Toll-like receptor (TLR) family. The objective of our study is to determine the relationship between rs4986790(+896A/G) and rs4986791(+1196C/T) gene polymorphisms and lung cancer risk.

The role of NOD1/CARD4 and NOD2/CARD15 genetic variations in lung cancer risk.

Background And Aim: NOD1/CARD4 and NOD2/CARD15 are members of the Nod-like receptor (NLR) family, and they contain a caspase recruitment domain (CARD). NLRs are located in the cytosol where they bind bacterial and viral ligands and play a key role in the innate and adaptive immune response, apoptosis, autophagy, and reactive oxygen species generation. NLR gene polymorphisms may shift the balance between pro- and anti-inflammatory cytokines and modulate the risk of infection, chronic inflammation, and cancer.

Detection of kinase amplifications in gastric adenocarcinomas.

Aim: To determine the incidences of copy number aberrations of receptor kinases and their relations in Turkish patients with gastric adenocarcinoma.

Materials And Methods: The prevalence of genomic copy number aberrations of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2)/topoisomerase IIa (TOP2A), centrosome-associated kinase aurora A (AURK A), centrosome-associated kinase aurora B (AURK B), and mesenchymal-epithelial transition factor (MET) genes and polysomies of related chromosomes were analyzed by fluorescent in situ hybridization (FISH) in tumor samples from 35 patients with gastric cancer.

Results: There were 28.

Ischemia-reperfusion injury in the liver during renal transplantation: does perfusion solution play any role?

The effect of ischemia-reperfusion (I/R) injury within a transplanted kidney has not been reported on the liver as a remote organ. One hypothesis is that there is no difference between kidney perfusion solutions regarding antioxidants in liver after an I/R injury. We used four pigs with Ringer's lactate (RL); four with university of Wisconsin (UW); and two in a control (C) group.

"Extarterectomy" for tumors invading the carotid artery: an animal model.

Objective: Carotid artery (CA) invasion by head and neck tumors is a challenging problem for the cranial base surgeon. Proposed methods for management have the disadvantage of constant or temporary interruption of the arterial blood flow and, as a consequence, cerebral ischemic complications. The objective of the study was to investigate the long-term effects of a novel technique, "extarterectomy," on the vascular wall and the arterial blood flow in an ovine model.

[A rare cause of bleeding intestinal intussusception in adult: jejunal lipoma].

Small bowel neoplasms are usually diagnosed when patients are referred with complications such as hemorrhage or obstruction. Intestinal lipomas are the third most frequent benign tumors among all intestinal neoplasms and their definite diagnosis is usually obtained after histopathological examination of the resected specimen. A 76 year-old male patient with partial intestinal obstruction and rectal bleeding at admittance was found to have an abdominal mass on ultrasound.
