A descriptive study of facial acanthosis nigricans and its association with body mass index, waist circumference and insulin resistance using HOMA2 IR.

Introduction: The term facial acanthosis nigricans (FAN) lacks definition of precise clinical and histopathological features. We present a descriptive study of patients with FAN to define pigmentary patterns and estimate the prevalence of obesity and insulin resistance in these cases.

Materials And Methods: It is a prospective study that included all patients with classical AN of the neck and/or other areas with facial acanthosis nigricans described as brown-to-black macular pigmentation with blurred ill-defined margins, found on the zygomatic and malar areas.

Novel Method for Real Time Co-Registration of IVUS and Coronary Angiography.

Objectives: We present our experience with a novel method for real time co-registration of intravascular ultrasound (IVUS) and coronary angiography.

Background: A major limitation of the current practice of concomitant use of coronary angiography and IVUS is that the locations of the acquired IVUS images are not correlated with their exact locations on the vessel roadmap obtained by coronary angiography.

Methods: Phantoms simulating the coronary tree were used to test the accuracy and potential of co-registration.

Acute pancreatitis complicated by ST-elevation myocardial infarction.

Background: Electrocardiographic abnormalities mimicking myocardial ischemia have been reported in intra-abdominal conditions, including acute pancreatitis. However, the occurrence of ST-elevation myocardial infarction (STEMI) is rare.

Objectives: To present a case report of a young man with acute pancreatitis subsequently complicated by acute STEMI.
