Which radiograph is most accurate for assessing hip joint penetration in infra-acetabular screw placement?

Medicine (Baltimore) 2021 Jun;100(24):e26392

Department of Orthopedic Surgery, Korea University Guro Hospital, Korea University Medical Center, Seoul, Republic of Korea.

Abstract: Although infra-acetabular screws have been used for anterior and posterior column transfixation, a screw penetrating the hip joint can result in harmful complications. However, the most accurate intraoperative radiologic imaging tool for identifying articular penetration has not been established. The purpose of the present study was, therefore, to evaluate the consistency with which standard pelvic radiographs compared with computed tomography (CT) can be used for demonstrating articular penetration.

Treatment Guideline for Patients with Native Culture-negative Pyogenic Vertebral Osteomyelitis.

Clin Orthop Relat Res 2021 Jun 15. Epub 2021 Jun 15.

Spine Center, Department of Orthopedics, Hallym University Sacred Heart Hospital, Hallym University College of Medicine, Anyang, Korea.

Background: With the development of evidence-based guidelines for the diagnosis and antibiotic treatment of patients with pyogenic vertebral osteomyelitis, various nonsurgical and surgical treatment strategies have achieved favorable results. However, sufficient administration of appropriate antibiotics is a prerequisite for treatment success, which cannot be guaranteed in patients with culture-negative pyogenic vertebral osteomyelitis. Unfortunately, previous studies on culture-negative pyogenic vertebral osteomyelitis were limited by small patient groups, short follow-up periods, varied treatment protocols, and inconsistently defined clinical endpoints.

Assessing the Impact of Wildfires on the Use of Black Carbon as an Indicator of Traffic Exposures in Environmental Epidemiology Studies.

Geohealth 2021 Jun 1;5(6):e2020GH000347. Epub 2021 Jun 1.

Environmental and Radiological Health Sciences Colorado State University Fort Collins CO USA.

Epidemiological studies frequently use black carbon (BC) as a proxy for traffic-related air pollution (TRAP). However, wildfire smoke (WFS) represents an important source of BC not often considered when using BC as a proxy for TRAP. Here, we examined the potential for WFS to bias TRAP exposure assessments based on BC measurements. Read More

Front Surg 2021 28;8:620964. Epub 2021 May 28.

Department of Trauma Surgery, Klinikum Rechts der Isar, Technical University of Munich, Munich, Germany.

Fractures of the calcaneus are severe injuries of the hindfoot, mostly resulting from high-energy axial loads, which still present enormous challenges to modern trauma surgery. Possible variables influencing the outcome are the type of fracture, age, and quality of fracture reduction. These might also be factors affecting the self-reported patient outcome, but large studies are still lacking. Read More

Research on Characteristic of Chronic Spontaneous Urticaria Based on Multiscale Entropy.

Comput Math Methods Med 2021 25;2021:6691356. Epub 2021 May 25.

College of Mathematical Sciences, Harbin Engineering University, Harbin 150001, China.

Chronic spontaneous urticaria (CSU) is a common skin disease which symptom is local pruritus and pain. In medicine, researchers take a certain point that the brain is the control center of CSU, but in previous experiments, the researchers found that cerebellum also had a certain effect on CSU. In order to find out the influence of CSU in the brain and cerebellum, we collected the brain resting-state fMRI data from 40 healthy controls and 32 CSU patients and used DPABI to preprocess.

Pharmacokinetic Study of Oral C-Radiolabeled Hyzetimibe, A New Cholesterol Absorption Inhibitor.

Front Pharmacol 2021 28;12:665372. Epub 2021 May 28.

Department of Clinical Pharmacology, Xiangya Hospital, Central South University, Changsha, China.

Hyzetimibe is a candidate drug being investigated as the second-in-class cholesterol absorption inhibitor; it lowers plasma levels of low-density lipoprotein cholesterol (LDL-C) by blocking the Niemann-Pick C1-like 1 protein, a transporter mainly expressed in the intestine that allows dietary cholesterol to enter the body from the intestinal lumen. Previous studies on the metabolism of hyzetimibe in healthy volunteers were not enough to show the biotransformation and excretion pathway; in particular, whether hyzetimibe maintains pharmacological action for duration sufficient to pass through the hepatic-intestinal circulation remains unknown. Furthermore, it remains unclear whether the differences between the chemical structures of ezetimibe and hyzetimibe would result in different pharmacokinetic characteristics. Read More
