Fluorescent Cholangiography in Laparoscopic Cholecystectomy: An Updated Canadian Experience.

Laparoscopic cholecystectomy (LC) is one of the most common general surgery procedures in Canada with approximately 100 000 cases performed per year. Bile duct injury remains a morbid complication with an incidence rate of 0.3% to 0.

Incisional wound VAC and risk-adjusted SSI rates in colorectal surgery: A tertiary centre experience.

Background: In colorectal surgery, indications for incisional negative pressure wound therapy (iVAC) remain unclear. We sought to compare rates of surgical site infection (SSI) in patients who received iVAC or standard sterile dressing (SSD).

Methods: Institutional colorectal NSQIP data between 2014 and 2018 was reviewed.

Do epinephrine auto-injectors have an unsuitable needle length in children and adolescents at risk for anaphylaxis from food allergy?

Background: Food allergy is the most common cause of anaphylaxis in children. Intramuscular delivery of epinephrine auto-injectors (EAI) is the standard of care for the treatment of anaphylaxis. We examined if children and adolescents at risk of anaphylaxis weighing 15-30 kg and >30 kg would receive epinephrine into the intramuscular space with the currently available EAI in North America and Europe.

Diagnostic quality assessment of compressed sensing accelerated magnetic resonance neuroimaging.

Purpose: To determine the efficacy of compressed sensing (CS) reconstructions for specific clinical magnetic resonance neuroimaging applications beyond more conventional acceleration techniques such as parallel imaging (PI) and low-resolution acquisitions.

Materials And Methods: Raw k-space data were acquired from five healthy volunteers on a 3T scanner using a 32-channel head coil using T2 -FLAIR, FIESTA-C, time of flight (TOF), and spoiled gradient echo (SPGR) sequences. In a series of blinded studies, three radiologists independently evaluated CS, PI (GRAPPA), and low-resolution images at up to 5× accelerations.

Follow-up evaluation with ultrasonography of peripheral nerve injuries after an earthquake.

Published data on earthquake-associated peripheral nerve injury is very limited. Ultrasonography has been proven to be efficient in the clinic to diagnose peripheral nerve injury. The aim of this study was to assess the role of ultrasound in the evaluation of persistent peripheral nerve injuries 1 year after the Wenchuan earthquake.

Children under 15 kg with food allergy may be at risk of having epinephrine auto-injectors administered into bone.

Background: The Epipen® Jr and Allerject® 0.15 mg are currently the most commonly prescribed epinephrine auto-injectors (EAIs) for the management of anaphylaxis in pediatric patients in North America and Canada. To ensure rapid absorption, it should be administered intramuscularly into the anterolateral aspect of the thigh.

Auto-injector needle length may be inadequate to deliver epinephrine intramuscularly in women with confirmed food allergy.

Background: Epinephrine auto-injectors are the standard first aid treatment for anaphylaxis. Intramuscular delivery into the anterolateral aspect of the thigh is recommended for optimal onset of action of epinephrine. The most frequently prescribed auto-injector in North America and Canada is the EpiPen(®), which has a needle length of 15.

Semi-automated scoring of pulmonary emphysema from X-ray CT: trainee reproducibility and accuracy.

Objective: We developed a semi-automated tool to quantify emphysema from thoracic X-ray multi-detector (64-slice) computed tomography (CT) for training purposes and multi-reader studies.

Materials And Methods: Thoracic X-ray CT was acquired in 93 ex-smokers, who were evaluated by six trainees with little or no expertise (trainees) and a single experienced thoracic radiologist (expert). A graphic user interface (GUI) was developed for emphysema quantification based on the percentile of lung where a score of 0=no abnormalities, 1=1-25%, 2=26-50%, 3=51-75% and 4=76-100% for each lung side/slice.

Quantitative computed tomographic predictors of compressive optic neuropathy in patients with thyroid orbitopathy: a volumetric analysis.

Purpose: To evaluate the relationship between orbital bony geometry and the volume of the intraorbital structures in predicting compressive dysthyroid optic neuropathy (DON).

Design: Retrospective, consecutive case series.

Participants: Images of 198 orbits from 99 patients suffering from thyroid-related orbitopathy were reviewed.

Clinical and soft-tissue computed tomographic predictors of dysthyroid optic neuropathy: refinement of the constellation of findings at presentation.

Objective: To evaluate the ability to predict the presence of dysthyroid optic neuropathy (DON) using computed tomography assessment of soft-tissue and clinical features.

Study Design: A retrospective consecutive case series of patients with thyroid-related orbitopathy.

Results: One hundred eighty-nine orbits from 99 patients were evaluated.
