Interplay Between Endocrine Disruptors and Immunity: Implications for Diseases of Autoreactive Etiology.

Front Pharmacol 2021 23;12:626107. Epub 2021 Mar 23.

Harvard Medical School, Boston, MA, United States.

The sex-bias of disease susceptibility has remained a puzzling aspect of several autoimmune conditions, including post-infection viral autoimmunity. In the last half of the twentieth century, the incidence rate of female-biased autoimmunity has steadily increased independent of medical advances. This has suggested a role for environmental factors, such as endocrine disrupting chemicals, which have been described to interfere with endocrine signaling. Read More

A Case of Sarcoidosis Mimicking Lymphoma Confounded by Cognitive Decline.

Cureus 2021 Mar 3;13(3):e13667. Epub 2021 Mar 3.

Internal Medicine, Wake Forest Baptist Medical Center, Winston-Salem, USA.

Sarcoidosis is a disease with an unknown cause that affects multiple organ systems and has a varied clinical presentation. Often, its symptomatology mimics other disease processes, such as lymphoma, tuberculosis, and amyloidosis. The reticuloendothelial involvement and typical B symptoms of weight loss, fatigue, night sweats, and lymphadenopathy can make sarcoidosis often easily confused with lymphoma. Read More

Mitochondrion 2021 Mar 31. Epub 2021 Mar 31.

Department of Medical Genetics, faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran. Electronic address:

Deficiency of the proteins involved in oxidative phosphorylation (OXPHOS) can lead to mitochondrial dysfunction. Polyribonucleotide nucleotidyltransferase 1 (PNPT1) is one of the genes involved in the OXPHOS and encodes the mitochondrial polynucleotide phosphorylase (PNPase) which is implicated in RNA-processing exoribonuclease activity. Herein, we report a 34-month-old boy who presented with global developmental delay, muscular hypotonia, hearing impairment, and movement disorders including chorea and dystonia. Read More

Tryptophan Metabolism and Gut-Brain Homeostasis.

Int J Mol Sci 2021 Mar 15;22(6). Epub 2021 Mar 15.

Department of Infectious Diseases & Immunology, University of Florida, Gainesville, FL 32608, USA.

Tryptophan is an essential amino acid critical for protein synthesis in humans that has emerged as a key player in the microbiota-gut-brain axis. It is the only precursor for the neurotransmitter serotonin, which is vital for the processing of emotional regulation, hunger, sleep, and pain, as well as colonic motility and secretory activity in the gut. Tryptophan catabolites from the kynurenine degradation pathway also modulate neural activity and are active in the systemic inflammatory cascade. Read More

Mediator-Related Symptoms and Anaphylaxis in Children with Mastocytosis.

Int J Mol Sci 2021 Mar 7;22(5). Epub 2021 Mar 7.

Department of Internal Medicine I, Division of Hematology & Hemostaseology, Medical University of Vienna, 1090 Vienna, Austria.

Mastocytosis is characterized by the pathological accumulation of mast cells (MC) in various organs. In these patients, MC may degranulate and thereby contribute to clinical symptoms, especially when a concomitant allergy is present. However, MC activation can not only be induced by high-affinity receptors for IgE, but also by anaphylatoxins, neuropeptides, IgG immune complexes, complement-components, drugs, products of bacteria or parasites, as well as physical factors such as heat, cold, vibration, stress, sun, or physical effort.

New Insights Into the Pathologic Roles of the Platelet-Activating Factor System.

Front Endocrinol (Lausanne) 2021 15;12:624132. Epub 2021 Mar 15.

Department of Pharmacology & Toxicology, Boonshoft School of Medicine at Wright State University, Dayton, OH, United States.

Described almost 50 years ago, the glycerophosphocholine lipid mediator Platelet-activating factor (PAF) has been implicated in many pathologic processes. Indeed, elevated levels of PAF can be measured in response to almost every type of pathology involving inflammation and cell damage/death. In this review, we provide evidence for PAF involvement in pathologic processes, with focus on cancer, the nervous system, and in photobiology. Read More

Transplant Cell Ther 2021 Mar 22;27(3):261.e1-261.e7. Epub 2020 Dec 22.

Hematology Department, Hospital Universitari i Politècnic La Fe, Valencia, Spain; CIBERONC, Instituto Carlos III, Madrid, Spain.

Central nervous system (CNS) involvement in Epstein-Barr virus-related post-transplant lymphoproliferative disorders (EBV-PTLDs) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is poorly defined. We analyzed the incidence, clinical and pathological characteristics, and impact on outcomes of EBV-PTLDs with CNS involvement (CNS-PTLDs) in 1009 consecutive adult patients undergoing allo-HSCT at a single-center institution. Four hundred eighty-two patients received matched sibling donor (MSD) transplants, 388 umbilical cord blood transplants (UCBTs), 56 matched unrelated donor (MUD) transplants, and 83 haploidentical transplants.

Microglial activation in the trigeminal spinal subnucleus interpolaris/caudalis modulates orofacial incisional mechanical pain hypersensitivity associated with orofacial injury in infancy.

J Oral Sci 2021 Mar 18;63(2):170-173. Epub 2021 Mar 18.

Department of Physiology, Nihon University School of Dentistry.

Purpose: Infantile tissue injury induces sensory deficits in adulthood. Infantile facial incision (IFI) was reported to cause an enhancement of incision-induced mechanical hypersensitivity in adulthood due to acceleration of the trigeminal ganglion neuronal excitability.

Schwannoma with Psammoma Body.

J Am Podiatr Med Assoc 2021 Feb;111(1)

We present a case of a 59-year-old male veteran with a chronic history of right foot soft-tissue mass that was causing pain in his shoes, but not functional or neurologic symptoms. Excision of the mass and pathologic evaluation resulted in multidisciplinary involvement and evaluation. In this example, the mass was found to be either an unusual schwannoma that happens to be psammoma body-rich or an unusual psammomatous melanocytic schwannoma that deviates from conventional examples, as a diagnostic consensus was unable to be reached.
