Validation of a Crisis Standards of Care Model for Prioritization of Limited Resources During the Coronavirus Disease 2019 Crisis in an Urban, Safety-Net, Academic Medical Center.

Objectives: The coronavirus disease 2019 pandemic has overwhelmed healthcare resources even in wealthy nations, necessitating rationing of limited resources without previously established crisis standards of care protocols. In Massachusetts, triage guidelines were designed based on acute illness and chronic life-limiting conditions. In this study, we sought to retrospectively validate this protocol to cohorts of critically ill patients from our hospital.

Effective Medical Lecturing: Practice Becomes Theory: A Narrative Review.

Effective lecturing stimulates learning, creates a verbal history for our profession, and is a central basis for evaluating academic promotion. Unfortunately, few resources exist in the medical literature to guide the academician toward success as an effective lecturer. Using evidence-based principles, this review fosters adult learning in academic venues by incorporating the latest innovations in educational theory for both online and traditional teaching.

Quantification of gastric mucosal microcirculation as a surrogate marker of portal hypertension by spatially resolved subdiffuse reflectance spectroscopy in diagnosis of cirrhosis: a proof-of-concept study.

Background And Aims: Portal pressure can be used to identify patients with chronic liver disease who have progressed to cirrhosis. Portal pressure can also provide accurate prognostication for patients with cirrhosis. However, there are no practical means for assessment of portal pressure.

Corneo-limbo-conjunctival transposition to treat deep and perforating corneal ulcers in dogs: A review of 418 eyes and corneal clarity scoring in 111 eyes.

Purpose: To report surgical and corneal clarity scores (CCSs) of corneo-limbo-conjunctival transpositions (CLCTs) in a large number of canine cases.

Methods: Retrospective review of records that underwent CLCT to repair deep ulcers or perforations between 2002 and 2018. Signalment, concurrent eye disease, additional procedures, pathogenesis, medication, graft orientation, follow-up, and CCSs were recorded.

A modified technique of keratoleptynsis ("letter-box") for treatment of canine corneal edema associated with endothelial dysfunction.

Purpose: To describe a modified keratoleptynsis procedure, as a method of preserving central corneal function, and evaluate the outcome in vision, reduction of corneal thickness and treatment of epithelial corneal ulcers in cases with endothelial cell dysfunction.

Methods: Forty-four dogs (72 eyes) were affected by progressive corneal edema, with or without ulcerative keratitis. All patients were treated with a dorsal and ventral superficial keratectomy followed by conjunctival flaps, maintaining a clear central cornea.

Successful Endoscopic Resection of Mucosa-Associated Lymphoid Tissue Lymphoma of the Colon.

Mucosa-associated lymphoid tissue lymphomas are the most common form of primary malignant gastrointestinal lymphoma. Although typically found in the stomach, extragastric locations have been described, in rare cases, the colon. The optimal management of these neoplasms remains uncertain and limited largely to small retrospective series or case reports.

Oculodermal Melanocytosis: Nevus of Ota in a Dog.

This report describes the clinical presentation, diagnosis, and histopathologic features of oculodermal melanocytosis in a young dog. A 3-year-old male neutered Labrador Retriever presented with conjunctival and scleral hyperpigmentation of the right eye, with concurrent ipsilateral cutaneous hyperpigmentation involving the right side of the face. Initial skin and conjunctival biopsies revealed an accumulation of histologically benign melanocytes within the dermis and conjunctival stroma, respectively.

Effective teaching of endoscopy: a qualitative study of the perceptions of gastroenterology fellows and attending gastroenterologists.

Background: There is little information describing the perceptions of gastroenterology fellows and attending gastroenterologists of what constitutes effective teaching of endoscopy. We sought to identify common themes regarding endoscopy training methods and their impact among fellows and attendings.

Methods: Focus group exercises and surveys were conducted among fellows, about educational resources, teaching techniques and ways of improving the teaching of endoscopy.

Successful medical treatment for globe penetration following tooth extraction in a dog.

A five-year-old entire male Tibetan Terrier was referred for left-sided periorbital swelling and blepharospasm 4 days following ipsilateral maxillary tooth extraction. Examination of the left eye revealed mild exophthalmos, pain on retropulsion, and absent menace response and pupillary light reflexes. Examination of the posterior segment was not possible owing to the anterior segment pathology.
