Letter: Unusual diathermy hazard.

Free gas in the peritoneal cavity: the final hazard of diathermy.

Fires and explosions in the operating theatre are rare events, but are devastating in terms of structural damage to the equipment in theatres and to human lives. Fuel, oxygen, and source of ignition are the three factors causing explosion. Explosion during emergency laparotomy for perforated bowel has not been reported in the literature. In the case reported here, fuel in the form of free gas c...

Short-Wave Diathermy

A good estimate of the value and interest of this book would be for one to attempt to review the large volume of literature on the subject of the development and uses of shortwave diathermy, which the author has studiously done. He has gleaned the rapidly accumulating published work of the past decade, previous to which little or nothing was written on the subject. An extensive bibliography is ...

Letter: Metastatic bronchogenic carcinoma: an unusual cause of localized arthritis.

than 10 percent of the cases. With increasing practice our yield in the diagnosis of localized lung disease is now well over 90 percent. This is a safe simple procedure which can be accomplished in any hospital where image-intensification fluoroscopy and good cytologic services are available. In summary, we feel that the preferred method for obtaining tissue from undiagnosed localized lung lesi...

Letter: An unusual effect of atropine on overdrive suppression.

To the Editor: By their elegant assessment of sinoatrial conduction during premature atrial stimulation, Strauss et al. (CIRCULATION 47: 86, 1973) have uncovered one major limitation of the rapid atrial pacing as a method of evaluating sinoatrial node automaticity by post drive suppression. This and probably other yet undiscovered facts may account for the inconsistent results obtained by this ...
