Acute Myeloid Leukemia in a Cholecystectomy Specimen.

A 76-year-old man was admitted into the ER for upper abdominal pain. Physical exam and CT scan confirmed acute cholecystitis with multiple cholelithis, and a cholecystectomy was performed. The cholecystectomy specimen showed chronic cholecystitis with exuberant inflammatory infiltrate.

Labile Calcium-Permeable AMPA Receptors Constitute New Glutamate Synapses Formed in Hypothalamic Neuroendocrine Cells during Salt Loading.

Magnocellular neuroendocrine cells (MNCs) of the hypothalamus play a critical role in the regulation of fluid and electrolyte homeostasis. They undergo a dramatic structural and functional plasticity under sustained hyperosmotic conditions, including an increase in afferent glutamatergic synaptic innervation. We tested for a postulated increase in glutamate AMPA receptor expression and signaling in magnocellular neurons of the male rat hypothalamic supraoptic nucleus (SON) induced by chronic salt loading.

Dermatophytic Pseudomycetoma of the Scalp.

Dermatophytic pseudomycetoma represents a chronic infection characterized by a tumor-like growth containing dermatophytes arranged as clustered aggregates (grains) within the dermis. In contrast to mycetomas, they lack sinus tracts and are more common in the scalp. We describe a dermatophytic pseudomycetoma arising in the scalp of an 18-year-old African-American woman.

Desmoplastic trichoepithelioma with pseudocarcinomatous hyperplasia: a report of three cases.

We report three cases of desmoplastic trichoepithelioma (DTE) with overlying pseudocarcinomatous hyperplasia. All three cases developed on the face of patients in their second decade. In spite of their young age, a diagnosis of squamous cell carcinoma was considered for each case, given the unusual juxtaposition of these two well-known simulators of malignancy.

Relationship between documentation status and survival for medically underserved Hispanic breast cancer patients.

Background: Undocumented immigrants have been shown to be predisposed to worse clinical outcomes than the general population. This study examines survival in socioeconomically disadvantaged Hispanic documented and undocumented breast cancer patients.

Methods: Analysis of a prospective breast cancer database of patients treated in a safety-net hospital system.

A multi-institutional study of pancreatic cancer in Harris County, Texas: race predicts treatment and survival.

Background: Racial disparities exist for patients with pancreatic cancer. This observation has primarily been noted in the Surveillance, Epidemiology, and End Results database and has focused primarily on whites and African Americans. We sought to determine if these disparities exist in a local, racially diverse patient population.
