Analysis of payments to GI physicians in the United States: Open payments data study.

Background And Aim: The purpose of this study was to review and analyze the nature of industry payments to gastroenterology and hepatology (GI) physicians.

Methods: We conducted a retrospective study of open payments (OP) data for the year 2017. Payments to individual physicians were aggregated using a unique physician profile identification number.

Polypectomy versus surgery in early colon cancer: size and location of colon cancer affect long-term survival.

Background And Aims: The colon cancer survival rate is significantly affected by location, stage, and size of the cancer. Polypectomy was shown be as equally effective as surgery in early-stage colon cancer, but there have been no established clinical guidelines in the management of colon cancer based on the size of the polyp or the tumor location. The aim of our study was to assess the early-stage colon cancer-specific survival rate in patients who underwent endoscopic polypectomy versus surgery, based on size and location of tumor in early-stage colon cancer.

Early Esophageal Cancer Specific Survival Is Unaffected by Anatomical Location of Tumor: A Population-Based Study.

Background. Approximately one-fifth of all esophageal cancer cases are defined as early esophageal cancer (EEC). Although endoscopic therapy (ET) has been shown to be equally effective as esophagectomy (EST) in patients with EEC, there is little information comparing the survival outcomes of the two therapies based on anatomical location.

The Anterior Subcutaneous Pelvic Fixator (INFIX) in an Anterior Posterior Compression Type 3 Pelvic Fracture.

Objectives: The purpose of this video is to describe the equipment, anatomy, and surgical technique of anterior subcutaneous pelvic fixation (INFIX) using pedicle screws and a rod in an Anterior Posterior Compression 3 pelvic fracture, as well as how to distract in lateral compression fractures.

Methods: The equipment required includes standard spine pedicle screw sets with long screws, 70-110 mm in length, and 7 or 8 mm in diameter. The approach is a mini open and one needs to be familiar with the iliac oblique, obturator outlet, and obturator inlet views.

The effect of smoking on ligament and cartilage surgery in the knee: a systematic review.

Background: The adverse effects of smoking on various health conditions such as cancer, diabetes, and cardiovascular disease have been well documented. Many orthopaedic conditions, such as fracture healing, wound repair, and bone mineral density, have been reported to be adversely affected by smoking. However, no known systematic reviews have investigated the effects of smoking on ligament and cartilage knee surgery.

Comparison of ACL fixation devices using cadaveric grafts.

We evaluated two newer forms of femoral fixation of hamstring grafts for anterior cruciate ligament reconstruction, the Endobutton direct (Smith and Nephew, Andover, MA) and Femoral intrafix (Depuy Mitek, Raynham, MA), and compare them to devices that have been evaluated in the literature, the AXL Crosspin (Biomet, Warsaw, IN) and Biotransfix II (Arthrex, Naples, FL). Paired hamstring tendon allografts were fixed in the femoral tunnel of 24 cadaveric bovine knees (6 per group) according to each device's specifications. The free ends (tibial sides) were fixed to the materials testing machine via custom-made cryo-clamps.

Signal-averaged electrocardiogram in physically healthy, recently abstinent chronic cocaine users.

Objectives: : Cocaine use is associated with cardiac arrhythmias. Markers of ventricular late potentials, which may be a precursor to malignant ventricular arrhythmias, can be detected by signal-averaged electrocardiography (SA-ECG) but not by standard ECG.

Methods: : We evaluated SA-ECG parameters in 60 medically screened, physically healthy, recently abstinent cocaine users (53 males, mean [SD] age, 34.

Signal-averaged electrocardiogram in physically healthy, chronic 3,4-methylenedioxymethamphetamine (MDMA) users.

Objectives: 3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) use has been associated with cardiac arrhythmias. Markers of ventricular late potentials (VLP), which may be a precursor to malignant ventricular arrhythmias, can be detected by signal-averaged electrocardiography (SA-ECG), but not by standard ECG.

Methods: We evaluated SA-ECG parameters in 21 physically healthy, recently abstinent MDMA users who also used cannabis (11 males, mean [SD] age 23.

Exercise stress testing in recently abstinent chronic cocaine abusers.

We compared treadmill exercise stress testing (EST) in 28 medically screened, chronic cocaine users with the cardiovascular effects of an IV cocaine challenge (25 mg or 50 mg). All subjects had a clinically normal EST and echocardiography (except 2 subjects had septal wall hypokinesis). The EST produced significantly greater increases in heart rate and rate-pressure product than did the cocaine challenges.
