We describe an extremely rare case of migraine-associated monocular diplopia developed in a 23-year-old man after sudden cessation of smoking. The physical examination and brain MRI scan were unremarkable. The symptoms resolved after starting nicotine patch. We reviewed the literature and discussed the diagnosis and possible mechanism of this phenomenon.
BACKGROUND Acute kidney injury (AKI) is common in patients with acute myocardial infarction. AKI in this setting is associated with short- and long-term adverse events. The aim of this study was to develop a simple score to predict AKI in patients presenting with acute myocardial infarction based on data available at time of admission. METHODS This was a(More)
Background. Blatchford and AIMS65 scores were developed to risk stratify patients with upper gastrointestinal bleed (UGIB). We sought to assess the performance of Blatchford and AIMS65 scores in predicting outcomes in elderly patients with nonvariceal UGIB. Methods. A retrospective cohort study of elderly patients (over 65 years of age) with nonvariceal(More)
Dipeptidyl peptidase-4 (DPP-4) inhibitors, such as saxagliptin, have gained a rapid growth in use in the treatment of type 2 diabetes mellitus in the past decade. Although they are considered to have a good safety profile, controversy exists regarding their potential to stimulate neoplasm growth. We report here a patient with metastatic carcinoid tumor.

Secondarily, HLH is often associated with autoimmune disease, infection, and malignancy. The most common infectious trigger is Epstein-Barr virus (EBV) infection. HLH is rarely triggered by parvovirus B19. We discuss a case of a(More)
Currently recommended treatment regimens for human monocytic ehrlichiosis (HME) include doxycycline or tetracycline. Antibiotic susceptibility studies demonstrate that rifampin has in vitro bactericidal activity against Ehrlichia. Case reports have suggested clinical response with rifampin treatment of human granulocytic anaplasmosis (HGA). We report the(More)
