The effect of histopathologic analysis and tissue cultures on inpatient management of cellulitis: a randomized control trial.

Background: In the absence of a gold-standard diagnostic modality for cellulitis, sterile inflammatory disorders may be misdiagnosed as cellulitis.

Objective: To determine the utility of skin biopsy and tissue culture for the diagnosis and management of patients admitted with a diagnosis of presumed cellulitis.

Design: Pilot single-blind parallel group randomized controlled clinical trial in 56 patients with a primary diagnosis of presumed cellulitis.

Tumor lysis Syndrome in a Patient with Metastatic Breast Cancer Treated with Alpelisib.

Purpose: Tumor lysis syndrome (TLS) is a rare but life-threatening phenomenon that occurs mainly in patients with aggressive hematologic or highly chemotherapy sensitive solid tumors such as high-grade neuroendocrine carcinoma or testicular cancer. Tumor lysis syndrome is exceedingly rare in hormone receptor-positive, HER2-negative breast cancer. Furthermore, TLS following treatment with alpelisib, a novel phosphatidylinositol 3-kinase (PI3K) inhibitor used to treat -mutated (gene encoding p110α subunit of PI3K), hormone receptor positive advanced breast cancer, has never been described in patients with nonhematologic malignancies.

Dermatologic manifestations of endocrine disorders.

The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual's health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes.

Ophthalmic manifestations of endocrine disorders-endocrinology and the eye.

Disorders of the endocrine system usually manifest in a multi-organ fashion. More specifically, many endocrinopathies become apparent in the eye first through a variety of distinct pathophysiologic disturbances. The eye provides physicians with valuable clues for the recognition and management of numerous systemic diseases, including many disorders of the endocrine pathway.

Discovery of Stromal Regulatory Networks that Suppress Ras-Sensitized Epithelial Cell Proliferation.

Mesodermal cells signal to neighboring epithelial cells to modulate their proliferation in both normal and disease states. We adapted a Caenorhabditis elegans organogenesis model to enable a genome-wide mesodermal-specific RNAi screen and discovered 39 factors in mesodermal cells that suppress the proliferation of adjacent Ras pathway-sensitized epithelial cells. These candidates encode components of protein complexes and signaling pathways that converge on the control of chromatin dynamics, cytoplasmic polyadenylation, and translation.
