Background: Neoadjuvant chemotherapy (NAC) is widely used in the treatment of primary breast cancer. Different staging systems have been developed to evaluate the residual tumor after NAC and classify patients into different prognostic groups. Ki67, a proliferation marker, has been shown to be useful in predicting treatment response and prognosis.

Article Synopsis
  • The study aimed to find out if combining special brain imaging techniques (DWI, MRS, and DSCI) could help doctors tell the difference between two types of brain tumors: high-grade glioma (HGG) and solitary brain metastasis (SBM).
  • They looked at 56 patients who had these imaging tests before their surgeries and compared certain measurements from each imaging technique to see which ones worked best.
  • The best combination of measurements that helped differentiate between HGG and SBM included three specific values, making it a really effective method with a high accuracy score of 0.970.

Article Synopsis
  • Epilepsy is a common brain disorder that can really affect how people live and their health.
  • Some patients don’t respond to regular epilepsy medications and may need surgery instead, but finding these patients can be hard and takes a lot of time.
  • This study uses advanced computer techniques to analyze medical data and identify which patients might not respond to medicine, which could help doctors make better decisions in the future.

Background: Naso/Orogastric tube (NOGT) misplacement can lead to significant complications. Therefore, the assessment of tube position is essential to ensure patient safety. Although radiography is considered the gold standard for determining NOGT location, new methods may be helpful in reducing repetitive radiation exposure, especially for neonates.

Objective: To investigate the prevalence of Burnout syndrome (BS) with its emotional exhausting (EE), depersonalization (DP), and personal accomplishment (PA) dimensions among Turkish urologists.

Material And Methods: A total of 2,259 certified Turkish urologists were invited by e-mail to participate in this cross-sectional survey-based study. An online survey was conducted to evaluate three dimensions of BS ie: -EE, DP and PA-and their association with socio-demographic variables of Turkish urologists using the Maslach Burnout Inventory (MBI).

: A major problem associated with immune thrombocytopenic purpura (ITP) in pregnancy is neonatal thrombocytopenia. We analyzed newborns born to mothers with ITP and examined predictive factors for thrombocytopenia. This retrospective study was performed in a single academic center from January 2007 to January 2018.

Article Synopsis
  • This study looked at how using special MRI techniques can help doctors tell the difference between low-grade and high-grade meningioma tumors.
  • They examined 45 patients and measured different MRI values related to the tumors before surgery.
  • The best way to identify high-grade tumors was by combining three specific MRI measurements, which made the diagnosis more accurate.

Objective: The purpose of this study was to assess the feasibility of 3-T susceptibility-weighted imaging (SWI) for detecting intraarticular hemosiderin accumulation in patients with hemophilia.

Subjects And Methods: Forty-one joints in 24 patients with hemophilia were imaged with conventional MRI and SWI sequences. Two experienced musculoskeletal radiologists and one general radiologist (reader 3) interpreted the images for hemosiderin accumulation.

Objectives: To evaluate the parenchymal elasticity of the thyroid gland with acoustic radiation force impulse imaging in pediatric patients with Hashimoto thyroiditis and to compare it with healthy volunteers.

Methods: Twenty-six patients with Hashimoto thyroiditis and 26 healthy volunteers between 6 and 17 years were included. The shear wave velocity (SWV) values of both thyroid lobes in both groups were evaluated.

Purpose: To evaluate the feasibility of quantitative analysis of muscle stiffness in the medial gastrocnemius muscle (GCM) by acoustic radiation force impulse (ARFI) ultrasound elastography in children with spastic cerebral palsy (CP).

Methods: Seventeen children with spastic CP and 25 healthy children participated in the study between the years 2016-2017. The medial GCM in the CP group was assessed using the Modified Ashworth Scale (MAS) by a physiatrist.

Tumour markers are widely used for the diagnosis, staging and monitoring of colorectal cancer (CRC) patients in clinical practice. Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most frequently used biomarkers in CRC patients. A number of studies have recently investigated the presence of human epididymis protein 4 (HE4) overexpression in certain cancer types.

Article Synopsis
  • The study aimed to determine if combining quantitative metrics (like mamillopontine distance) with qualitative signs (such as dural enhancement) improves the diagnosis of intracranial hypotension (IH).
  • Researchers analyzed data from 34 patients and 34 control subjects using statistical methods to assess the diagnostic performance and establish optimal cutoff values for IH diagnosis.
  • Results indicated that a combination of specific metrics and signs (dural enhancement, venous engorgement, and mamillopontine distance) achieved a diagnostic accuracy of 100% for IH, suggesting improved accuracy in identifying the condition.

Purpose: Acoustic radiation force impulse imaging is a kind of shear wave elastography that can be used in children for differentiating thyroid pathologies. Possible changes in the healthy thyroid gland in children may create difficulties in the use of shear wave velocities (SWV) in thyroid pathologies. The aim of this study was to define the normal values of SWV for the healthy thyroid gland in children, elucidate the correlation of the SWV values with potential influencing factors, and evaluate intra-operator reproducibility of the SWV.

  • The study aimed to assess kidney elasticity in children with chronic kidney disease (CKD) using acoustic radiation force impulse imaging and compare the results with those from healthy volunteers.
  • It involved 30 pediatric CKD patients and 38 healthy individuals, revealing significantly lower shear wave velocity (SW) values in CKD patients across all stages compared to healthy volunteers, with a notable exception for stage 5.
  • While the technique showed promise for identifying CKD, particularly at a cutoff SW value of 1.81 m/s, it was not effective in predicting the specific stages of the disease, except for stage 5.
