In inferior myocardial infarction, neither ST elevation in lead V1 nor ST depression in lead I are reliable findings for the diagnosis of right ventricular infarction.

Objective: In the presence of inferior myocardial infarction (MI), ST depression (STD) in lead I has been claimed to be accurate for diagnosis of right ventricular (RV) MI. We sought to evaluate this claim and also whether ST Elevation (STE) in lead V1 would be helpful, with or without STD in V2.

Methods: Retrospective study of consecutive inferior STEMI, comparing ECGs of patients with, to those without, RVMI, as determined by angiographic coronary occlusion proximal to the RV marginal branch.

ST depression in lead aVL differentiates inferior ST-elevation myocardial infarction from pericarditis.

Background: ST-segment elevation (STE) due to inferior STE myocardial infarction (STEMI) may be misdiagnosed as pericarditis. Conversely, this less life-threatening etiology of ST elevation may be confused for inferior STEMI. We sought to determine if the presence of any ST-segment depression in lead aVL would differentiate inferior STEMI from pericarditis.

The Pittsburgh Fistula Classification System: a standardized scheme for the description of palatal fistulas.

Objective: Vague terminology is a problem in cleft palate research. No classification scheme for palatal fistulas has been proposed to date. Although a well-healed velum is a significant outcome of palatoplasty, it is nearly impossible to compare fistula-related palatoplasty results in the literature or in medical records without a standardized vocabulary.

A human glucagon-like peptide-1 receptor polymorphism results in reduced agonist responsiveness.

Glucagon-like peptide-1 (GLP-1) and its cognate receptor play an important physiological role in maintaining blood glucose homeostasis. A GLP-1 receptor (GLP-1R) polymorphism in which threonine 149 is substituted with a methionine residue has been recently identified in a patient with type 2 diabetes but was not found in non-diabetic control subjects. We have functionally assessed the recombinant GLP-1R variant after transient expression in COS-7 and HEK 293 cells.
