Pure Nitrous Oxide and Possibly Phthisis from Dr. J. K. Carmichael

Brother of a horseman, James K. Carmichael (1864 to 1894) was raised in Rensselaer County, New York. After studying dentistry, he set up practice in Hartford, Connecticut. There he met the daughter of a harness maker, his future wife Jennie Pearl. Dr. Carmichael issued this trade card (top) from his Main Street “head-quarters for pure nitrous oxide gas” (bottom). A few years after his 1888 marriage, his pulmonary tuberculosis became so severe that a Dr. Pease had to cover the office. While battling “phthisis” at a health resort in Colebrook, New Hampshire, 29-yr-old Dr. Carmichael died. Back in the 1880s, many dentists gauged the quality of their laughing gas by breathing it from the mouthpiece or mask. We can only speculate whether patients may have contracted “consumption” from Dr. C armichael. (Copyright © the American Society of Anesthesiologists’ Wood Library-Museum of Anesthesiology.)

ConclusionA review of the literature shows that Intussusception through an ileostomy can occur at any time after the first surgery. The cause is still unclear. Urgent conservative surgical management based on manual reduction should be preferred.

Abstract Benzocaine has been well-known for its role as anesthetic agent and largely used in oral ulcers, ear pain and dental complications. Along with lidocaine and other local anesthetics, benzocaine has marked its part as an anesthetic in surgical procedures and as Na+ channels blocker, as well. Analogues of benzocaine have been found to possess biological potentials including antibacterial antifungal and anti-cancer. Some derivatives were found to have conspicuous action against tuberculosis. Current review focuses to explore the century long potential of the molecule and its analogs that have appeared in the ...

Human immunodeficiency virus (HIV), tuberculosis (TB) and malaria are commonly encountered when working in tropical countries and may have an impact upon anaesthesia, either as a direct result of the condition or due to interaction with the ...

We examined the relationship between the metabolic processes of carbon catabolite repression (CCR), nitrogen catabolite repression (NCR) and virulence in a variety of A. fumigatus clinical isolates. A considerable amount of heterogeneity with respect to the degree of CCR and NCR was observed and a positive correlation between NCR and virulence in a neutropenic mouse model of pulmonary aspergillosis (PA) was found. Isolate Afs35 was selected for further analysis and compared to the reference strain A1163, with both strains presenting the same degree of virulence in a neutropenic mouse model of PA. Afs35 metabolome analysis ...

​Seventy-five percent of trauma injuries involve some kind of thoracic insult, a quarter of which need a procedural intervention like a chest tube. (Surg Clin North Am 2007;87[1]:95; http://bit.ly/2HaoX90.) Long-term illness, lung disease, and post-operative complications may cause pleural effusions or a pneumothorax, so treating these conditions quickly can significantly decrease patient morbidity and mortality. Other indications for chest tube placement include:Trauma: Pneumothorax, hemopneumothorax, or tension pneumothoraxLong-term illness: Pleural effusion (cancer, pneumonia)Infection: Empyema, purulent pleuriti...
