The Onset of In-Vivo Dehydration in Gas -Based Intraperitoneal Hyperthermia and Its Cytotoxic Effects on Colon Cancer Cells. Front Oncol 2022; 12:927714.

Abstract
Background Peritoneal metastasis (PM) is an ongoing challenge in surgical oncology. Current therapeutic options, including intravenous and intraperitoneal (i.p.) chemotherapies display limited clinical efficacy, resulting in an overall poor prognosis in affected patients. Combined hyperthermia and dehydration induced by a high-flow, gas-based i.p. hyperthermic procedure could be a novel approach in PM treatment. Our study is the first to evaluate the therapeutic potential of i.p. dehydration, hyperthermia, as well as the combination of both mechanisms in an in-vivo setting. Methods For this study, three swine were subjected to diagnostic laparoscopy under a high-flow air stream at 48°, 49° and 50°Celsius (C). Hygrometry of the in- and outflow airstream was measured to calculate surface evaporation and i.p. dehydration. To analyze the effects of this concept, in vitro colon cancer cells (HT-29) were treated with hyperthermia and dehydration. Cytotoxicity and cell viability were measured at different time intervals. Additionally, structural changes of dehydrated cells were analyzed using scanning electron microscopy. Results According to our results, both dehydration and hyperthermia were cytotoxic to HT-29 cells. However, while dehydration reduced cell viability, hyperthermia did not. However, dehydration effects on cell viability were significantly increased when combined with hyperthermia (p<0.01). Conclusions Changes to the physiological milieu of the peritoneal cavity could significantly reduce PM. Therefore, limited dehydration of the abdominal cavity might be a feasible, additional tool in PM treatment. Further studies are required to investigate dehydration effects and their applicability in PM management.

ARMOCIDA E, MARTINI M. Tuberculosis: a timeless challenge for medicine. JOURNAL OF PREVENTIVE MEDICINE AND HYGIENE 2020; 61:E143-E147. [PMID: 32802997 PMCID: PMC7419119 DOI: 10.15167/2421-4248/jpmh2020.61.2.1402] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Accepted: 11/28/2019] [Indexed: 11/16/2022]
Abstract
This overview shows how tuberculosis has represented and still represents a continuous challenge for Medicine. Starting from the dawn of medicine, when tuberculosis was called “phthisis” by Hippocrates, passing through the discovery of the tubercles and the creation of the word “tuberculosis”, following the application of the anatomo-clinical method, until the discovery of a microscopic enemy: Mycobacterium tuberculosis. The progressive discovery of the pathological basis of tuberculosis has allowed to devise important therapeutic strategies in Pre-Antibiotic and Post-Antibiotic Era. In particular, “antibiotic therapy” had to be the end of the challenge between man and tuberculosis. However it was only an illusion. Despite progress in care and prevention, tuberculosis remains one of the world’s leading causes of ill-health and the first cause of death from infectious disease. Nowadays, the drug resistance, individuals with immune deficiencies, the ageing and globalization are just some of the causes responsible for the increasing of the challenge between man and tuberculosis.

Abstract
Carlo Forlanini (1847–1918), a medical doctor professor at the universities of Turin and Pavia, was the inventor of artificial pneumothorax, a method that allowed a first significant victory in the long war of medicine against pulmonary tuberculosis. The article outlines a portrait of this important clinician and focuses on the therapeutic innovation he introduced for the treatment of this infectious disease.

No Silver Medal for Nobel Prize Contenders: Why Anesthesia Pioneers Were Nominated for but Denied the Award. Anesthesiology 2016; 125:34-8. [PMID: 26982509 DOI: 10.1097/aln.0000000000001099] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
Taking the examples of the pioneers Carl Ludwig Schleich, Carl Koller, and Heinrich Braun, this article provides a first exploratory account of the history of anesthesiology and the Nobel Prize for physiology or medicine. Besides the files collected at the Nobel Archive in Sweden, which are presented here for the first time, this article is based on medical literature of the early 20th century. Using Nobel Prize nominations and Nobel committee reports as points of departure, the authors discuss why no anesthesia pioneer has received this coveted trophy. These documents offer a new perspective to explore and to better understand aspects of the history of anesthesiology in the first half of the 20th century.
