The vision transformer (ViT) architecture, with its attention mechanism based on multi-head attention layers, has been widely adopted in various computer-aided diagnosis tasks due to its effectiveness in processing medical image information. ViTs are notably recognized for their complex architecture, which requires high-performance GPUs or CPUs for efficient model training and deployment in real-world medical diagnostic devices. This renders them more intricate than convolutional neural networks (CNNs).

By adjusting the synthesis temperature, we successfully produced FeO nanorods and nanospheres. In addition, the 2-octanol, and the surfactant cetyltrimethylammonium bromide served as a solvent in the synthesis process.

Materials And Methods: Thirty-five consecutive patients (12 men and 23 women; mean age, 62 ± 11.3 [SD]; range: 39-89 years) treated between 2019 and 2021 were retrospectively included.
The purpose of this retrospective review was to evaluate SpineJack implantation in cancer-related vertebral compression fractures in 13 consecutive patients (mean age, 62.8 years ± 18.8).

To further drive cement deposition during vertebroplasty, the aims of this restrospective case series study were to report the feasibility, safety and short term efficacy (≤6 months) of percutaneous vertebral fixation in cancer-related vertebral compression fractures using various intravertebral implants. All consecutive cancer patients treated with percutaneous vertebral fixation for VCF were retrospectively included.

Like any operators, interventional radiologists are exposed to the risk of work-related musculoskeletal disorders. The use of lead shielding to radiation exposure and the lack of ergonomic principles developed so far contribute to these disorders, which may potentially affect their livelihoods, quality of life, and productivity.

Materials And Methods: Patient characteristics (age, body mass index (BMI)), anatomical conditions (number of prostatic arteries, anastomosis), and technical factors (use of cone beam computed tomography (CBCT), large display monitor (LDM), and magnification) were recorded as well as total air kerma (AK), dose area product (DAP), fluoroscopy time (FT), and number of acquisitions (NAcq). Associations between potential dose-influencing factors and AK using univariate analysis and a multiple linear regression model were assessed.
This review aimed to identify the potential role of integrative medicine in interventional oncology. The music therapy; stress management techniques; guided imagery, including virtual reality; clinical hypnosis; and digital sedation may all be efficient on anxiety and pain during procedures performed in interventional oncology. Beyond pharmacological sedation, the implementation of integrative medicine to interventional oncology may, therefore, improve the support and care of cancer patients, which may further create a virtuous alliance.

As all treatment modality, renal ablation has matured technically. Radiofrequency ablation, microwave ablation or cryoablation are now performed in many institutions under imaging guidance.

All are performed under minimally invasive conditions using imaging guidance. Selection of a technique over another follows guidelines but also patient's status and availability of the techniques.

Two patients underwent percutaneous image-guided electrochemotherapy on blastic spine metastases involving posterior walls of the lumbar vertebral bodies with epidural extension. These treatments were performed safely under cone beam computed tomography. Local tumor control was obtained on the subsequent follow-up as well as pain relief and disability improvement.
View Article and Find Full Text PDFTumor-related vertebral compression fractures often result in severe back pain as well as progressive neurologic impairment and additional morbidities. The fixation of these fractures is essential to obtain good pain relief and to improve the patients' quality of life. Thus far, several spine implants have been developed and studied.

Observations: These meningitis were diagnosed during tow months and with 3 different operators.
Background: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive inherited metabolic disease, characterized by progressive kidney failure due to renal deposition of calcium oxalate. Mutations in the AGXT gene, encoding the liver-specific enzyme alanine glyoxylate aminotransferase, are responsible for the disease. We aimed to determine the mutational spectrum causing PH1 and to provide an accurate tool for diagnosis as well as for prenatal diagnosis in the affected families.

Methods: We included parturients proposed for Cesarean under SA. They were not included the women of statute ASA > II, preeclamptics, eclamptics and/or having counter-indications of SA.
Background: Spinal anaesthesia for caesarean section exposes to high incidence of arterial hypotension which can result in maternal and neonatal morbidity. We hypothesized that the reduction of this dose from 10 mg to 7.5 mg would minimize hypotension without altering pain relief.
View Article and Find Full Text PDFBackground And Objective: Spinal anaesthesia for caesarean section is commonly associated with hypotension and crystalloid preload is widely recommended. Low-dose spinal appears to cause less hypotension. The aim of this study was to investigate whether the combined use of crystalloid preload and low dose spinal anaesthesia might further reduce the rates of hypotension.

Aim: In this study, we are interested to the determination of under groups of patients for whom the advantages of the prophylaxis of the thromboembolic disease (TED) are higher than its disadvantages.
Methods: We proceeded to a retrospective study based on patient medical records ranging from March 2003 until March 2004, enrolling 56 consecutive patients.
Experts from all continents discussed the present and future of nephrology and transplantation medicine in emerging countries during a 3-day conference, supported by the World Health Organization, the International Society of Nephrology, the Transplantation Society-Global Alliance for Transplantation and the Ministry of Health of the Republic of Mali. This conference was held in Bamako, Mali on December 4-6, 2008, and focused on prevention and treatment of chronic kidney disease in emerging countries. Apart from delivering high-quality medical and scientific knowledge, the meeting was mainly a call to action for emerging countries to start chronic kidney disease prevention and screening programs, develop end-stage renal disease registries and start or further elaborate transplantation programs.
