Phase I Study of IGF-Methotrexate Conjugate in the Treatment of Advanced Tumors Expressing IGF-1R.

Objectives: Insulin-like growth factor-methotrexate (IGF-MTX) is a conjugate of methotrexate and 765IGF, a variant of IGF-1 with high affinity for insulin-like growth factor type 1 receptor. The study aim was to determine the maximum tolerated dose of IGF-MTX in refractory solid organ and hematologic malignancies expressing insulin-like growth factor type 1 receptor.

Materials And Methods: This phase I trial used a modified toxicity probability interval design with 5 cohort dose levels, and expansion cohort at maximum tolerated dose.

FOXM1 contributes to treatment failure in acute myeloid leukemia.

Acute myeloid leukemia (AML) patients with NPM1 mutations demonstrate a superior response to standard chemotherapy treatment. Our previous work has shown that these favorable outcomes are linked to the cytoplasmic relocalization and inactivation of FOXM1 driven by mutated NPM1. Here, we went on to confirm the important role of FOXM1 in increased chemoresistance in AML.

Osseous Rosai-Dorfman Disease Presenting as a Solitary Lesion of the Distal Radius.

Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy, is a rare entity in which bone involvement occurs in less than 5% to 10% of patients and skeletal cases are usually multifocal. Extranodal solitary lesions of bone without nodal involvement or additional clinical manifestations are exceedingly rare. We present the clinical course and management of a 34-year-old African American woman who presented with the disease as a solitary lesion of the distal radius.

EBV-positive post-transplant lymphoproliferative disorder presenting as primary diffuse large B-cell lymphoma of the central nervous system.

Primary central nervous system post-transplant lymphoproliferative disorder (PCNS-PTLD) is a rare complication with inferior survival outcomes in solid organ transplant patients. It represents approximately 7-15% of all PTLD patients. Because of the rarity of this disease, the diagnosis of PCNS-PTLD is often challenging, and the optimal therapy has not been established.

Granulomas within renal epithelial neoplasms in patients with sarcoidosis: A causal association?

Sarcoidosis is a chronic granulomatous disease that can involve virtually every organ system, but most commonly presents as lung, skin, or lymph node disease. Although kidney involvement is usually clinically silent, granulomatous interstitial nephritis - the hallmark of renal sarcoidosis - can lead to functional impairment and organ failure. Also, recent studies have suggested an association between sarcoidosis and an increased risk of developing kidney tumors.

Atypical Plasmacytic Proliferation in a Case of C3 Glomerulopathy: Pathophysiology Demystified.

An 11-year-old Hispanic female underwent evaluation of asymptomatic proteinuria and hematuria. The patient denied fever, edema, and gross hematuria. Urinalysis showed mild proteinuria, and a urine microscopic examination revealed red blood cells.

Terminal innervation of female genitalia, cutaneous sensory receptors of the epithelium of the labia minora.

Introduction: Little information is available regarding the sensory nerve endings within the glabrous skin of the external female genitalia. The diversity of possible sensations suggests a variety of receptor types. Comprehensive knowledge of the sensory stimuli, including stimulus position, changes in temperature, pressure and pain, is critical for addressing pain and sexual function disorders clinically.

Terminal innervation of the male genitalia, cutaneous sensory receptors of the male foreskin.

Purpose: Understanding the types of sensory nerve termini within the glabrous skin of the human male foreskin could throw light on surgical outcomes and therapeutic possibilities for the future. Various receptor types sense changes in temperature, position, pressure, pain, light touch, itch, burning and pleasurable sexual sensations. Similarities and differences in innervation characteristics and density might become apparent when the glans penis is compared with homologous structures in the female genitalia.

Rare presentation of intracranial vascular blowout after tumor resection and radiation therapy.

A middle-aged patient presented with a rapidly growing right dural-based extra-axial posterior clinoid mass extending to the right cavernous sinus that was surgically resected. Histological examination showed solid growth of primitive neuroectodermal tumor arising from the third nerve. Following surgical resection, the patient was further managed by radiation and chemotherapy.

Inhibitory effects of 405 nm irradiation on Chlamydia trachomatis growth and characterization of the ensuing inflammatory response in HeLa cells.

Background: Chlamydia trachomatis is an intracellular bacterium that resides in the conjunctival and reproductive tract mucosae and is responsible for an array of acute and chronic diseases. A percentage of these infections persist even after use of antibiotics, suggesting the need for alternative treatments. Previous studies have demonstrated anti-bacterial effects using different wavelengths of visible light at varying energy densities, though only against extracellular bacteria.

Immunocytochemical characterization of pacinian-like corpuscles in the labia minora of prepubertal girls.

Study Objective: To better understand the precise role of sensory corpuscles within the female external genitalia.

Design: After IRB approval, waste tissue samples were obtained from 10 normal girls (aged 2-9 years) who underwent surgery for labial fusion. Immunocytochemistry against protein gene product 9.
