Background: Piriformis syndrome, which is seen as the cause of 0.3% to 6% of low back pain, is a painful condition that occurs as a result of compression of the piriformis muscle on the sciatic nerve. Although there are many studies in the literature about piriformis syndrome, no bibliometric analysis has been found.

It is important to investigate the changes in the masseter muscle, one of the chewing muscles, in epilepsy patients and to determine whether epilepsy can be effectively predicted on muscle. The aim of this study is to measure masseter muscle thickness, circumference and cross-sectional area in individuals with epilepsy and healthy individuals. This study was performed with 128 individuals (64 epilepsy patients and 64 healthy subjects) aged between 18 to 59 years.

Objective: Respiratory syncytial virus (RSV) is the primary etiology of lower respiratory tract infection in children. The fluctuating incidence of RSV, particularly in light of the COVID-19 pandemic, has shifted the spotlight onto preventive strategies. Our study aims to investigate both the risk factors and clinical symptoms of RSV.

A long-standing goal in neuroscience is to understand how a circuit's form influences its function. Here, we reconstruct and analyze a synaptic wiring diagram of the larval zebrafish brainstem to predict key functional properties and validate them through comparison with physiological data. We identify modules of strongly connected neurons that turn out to be specialized for different behavioral functions, the control of eye and body movements.

Background: This study aimed to compare the effects of microfracture (MF) versus intra-articular hyaluronic acid (HA) + oral glucosamine and chondroitin sulfate (GC) in addition to MF in patients with osteoarthritic knees who underwent medial open wedge high tibial osteotomy (MOWHTO) after an average follow-up of five years.

Methods: The study was designed retrospectively and included patients who underwent MOWHTO due to gonarthrosis, the MF method performed on these patients, and HA + GC treatments applied in addition to MF. Three groups consisting of 79 patients were formed: only HTO (Group 1), HTO + MF (Group 2), and HTO + MF + HA + GC (Group 3).

Background: Hyperlactatemia has been recognized as a significant prognostic indicator in critically ill patients. Nonetheless, there remains a gap in understanding the specific risk factors contributing to increased mortality among undifferentiated emergency department (ED) patients presenting with elevated lactate levels.

Objectives: The objective of the study is to investigate potential risk factors for 30-day in-hospital mortality in ED patients with hyperlactatemia.

Article Synopsis
  • This study investigates out-of-hospital cardiac arrest (OHCA) data in Türkiye, focusing on prognostic outcomes and influencing factors for patients aged 18 and older who were treated at 28 medical centers.
  • It found a survival rate upon hospital discharge of only 4.4%, with a significant majority of patients not receiving bystander CPR, which was only performed in 2.9% of cases.
  • Key predictors for better outcomes included male gender, initial shockable heart rhythms, shorter prehospital CPR duration, and no need for CPR in the emergency department, highlighting the importance of timely and effective CPR in emergencies.

Aim: To evaluate the effects of granulocyte colony stimulating factor (G-CSF) on spinal fusion through manual palpation, radiological examinations, and histopathological analyses in a rat model.

Material And Methods: A total of 21 rats were evaluated in this study. The rats were divided into the following three groups, each consisting of seven rats: preoperative G-CSF, postoperative G-CSF, and a control group.

Background: Pulmonary embolism requires careful differential diagnosis as it is associated with a wide range of symptoms that may suggest different diseases such as chest pain, shortness of breath and syncope. Since the disease can be fatal, especially in cases where right ventricular failure and hemodynamic instability develop, prognostic markers are great importance in terms of monitoring the patient during the treatment process.

Aim: We aimed in our study to compare the relationship between the ratio of D-dimer and High Sensitive Troponin T (HsTnT) values ​​with short-term mortality and to compare this relationship with Pulmonary Embolism Severity Index (PESI) scoring.

This study aimed to determine the effectiveness of extracorporeal shockwave lithotripsy (SWL) performed in the early period (within the first 24 hours). Data of patients who underwent SWL with a diagnosis of unilateral radiopaque 5 to 10 mm upper ureteral stones were retrospectively examined. Patients were divided into 2 groups.

Background: Intracranial hemorrhages is one of the major causes of mortality and morbidity worldwide, and there is still no effective biomarker to predict prognosis.

Aim: We aimed to determine the effectiveness of high sensitive troponin I (hs-cTn-I) levels to predict the prognosis of spontaneous intracerebral hemorrhage (sICH) by comparing Glasgow Coma Score (GCS) and hematoma volume with hs-cTn-I levels.

Methods: This study was planned as a retrospective observational study.

Objective: In this study, the aim was to compare the results of mini and standard percutaneous nephrolithotomy (PCNL) for the treatment of pediatric kidney stones.

Materials And Methods: Data for 128 patients < 18 years of age who underwent mini and standard PCNL due to pediatric kidney stones were retrospectively examined. Patients were divided into two groups: mini-PCNL (16-20 Fr) and standard PCNL (26 Fr).

Objective: This study aimed to compare the clinical outcomes and complications of obese patients who underwent extracorporeal shock wave lithotripsy (ESWL) and flexible ureterorenoscopy (FURS) for treating 1-2 cm renal pelvic stones.

Methods: This study included 89 patients with a body mass index (BMI) >30 who underwent ESWL and FURS surgeries for 10-20 mm renal pelvic stones between January 2015 and July 2023. Three months after the treatments, patients underwent full abdominal computed tomography (CT) and were examined for stone-free status and the presence of residual stones.

Migration of intrauterine devices (IUDs) to the ureter causing ureteral obstruction is an extremely rare event. A 45-year-old female patient was admitted to our hospital with a complaint of pain in the right flank and inferior right quadrant of the abdomen. On genitourinary system ultrasonography, grade 3 hydronephrosis was found in the right kidney.

Introduction: Seizure quality is considered to be associated with treatment outcomes of electroconvulsive therapy (ECT). A wide range of treatment parameters and patient characteristics are known to influence seizure quality. However, conflicting results exist for the role of serum electrolyte levels and seizure quality.

The nervous system reorganizes memories from an early site to a late site, a commonly observed feature of learning and memory systems known as systems consolidation. Previous work has suggested learning rules by which consolidation may occur. Here, we provide conditions under which such rules are guaranteed to lead to stable convergence of learning and consolidation.

Growth-preservation techniques are utilized in early onset scoliosis (EOS) cases requiring surgical intervention. The Shilla technique corrects the deformity by reducing additional surgeries with its growth-guidance effect. As with other techniques, various problems can be encountered following the administration of the Shilla technique.

Neuronal wiring diagrams reconstructed by electron microscopy pose new questions about the organization of nervous systems following the time-honored tradition of cross-species comparisons. The C. elegans connectome has been conceptualized as a sensorimotor circuit that is approximately feedforward, starting from sensory neurons proceeding to interneurons and ending with motor neurons.
