Rest in Neurasthenia and Allied States
Published in Francis X. Dercum, Rest, Suggestion, 2019
Occasionally in spite of the rest, the bathing, and the massage, the various fatigue sensations, pains, and aches of which the patient complains persist for an unduly long period. Pains thus persisting are probably due to the retention of waste products, especially of the uric acid or alloxuric group. This point I regard as of great importance and of special significance because of the close relation existing between neurasthenia and the so-called uric acid diathesis. Indeed, it has become my rule to regard aching pains in neurasthenia, when persistent, as of diathetic origin and demanding diathetic treatment. Usually they yield more or less readily to such measures. Some salicylate which is well borne by the stomach should be given, such as aspirin, salophen, or salol. Aspirin in five- to fifteen-grain doses three or four times a day is usually very efficient. When the stomach is in good condition, sodium salicylate, ten or fifteen grains, with an equal or slightly larger quantity of sodium bromid may be given in a large quantity of water after meals. The salicylates are efficacious not only in the backache and limbache of neurasthenia, but also in many of the persistent headaches. An alkaline treatment by means of lithia waters may also be instituted, or, what is better, piperazin, lycetol, or atophan may be given along with large quantities of water.
Metal-ceramic and porcelain-veneered lithium disilicate crowns: a stress profile comparison using a viscoelastic finite element model

In the last 30 years, the development of the pressing technique for glass-ceramics and the Computer Aided Design/Computer Aided Machining (CAD/CAM) technology have allowed the fabrication of strong ceramic frameworks that is combined with a porcelain overlay to achieve the most esthetic results (Zhang and Kelly 2017). Also with the advent of finite element method (FEM), simplified models have been developed that has eased this fabrication process (Martorelli and Ausiello 2013). Among the available ceramic frameworks, lithia- and zirconia-based ceramics are the popular choices for metal-free systems (Zarone et al. 2019). Porcelain-veneered zirconia (PVZ) has been the most popular and widely studied alternative for MC. However, concerns of the high rates of porcelain fracture and chipping and crown debonding have cast a shadow over their widespread applications (Pang et al. 2015; Pjetursson et al. 2015; Sailer et al. 2015; Nicolaisen et al. 2016).
The Oslerian legacy in the Southern states
Published in Baylor University Medical Center Proceedings, 2019
Dr. Hurst’s question about Osler traveling to Americus may have an answer in certain clues. Osler’s trip involved a train and a resort. The barbecue at Lithia Springs, about 15 miles west of Atlanta, necessitated a train ride (Figure 2). Lithia Springs did feature spas at its resorts, and the therapeutic water naturally carried a touch of lithium. The train that conveyed over 2000 people to the barbecue was
