In comparison with other hazards of anesthesia, fires and explosions occur very infrequently because of precautions for their prevention so that they are relatively insignificant. The authors had experience of a case of explosion with fire in an oxygen delivery tube and the wrapping cloth of the oxygen cylinder. A piece of plaster used for prevention of leakage from the oxygen delivery tube occluded the filter in a pin-index system of an anesthesia machine. It is suspected that adiabatic compression may produce a momentary temperature of over 900 degrees C in an occluding part, thus igniting minute particles detached by the gas stream from the walls of the oxygen delivery tube. In case of malfunctioning in anesthetic apparatus, it should be repaired only by expert engineers.

Stapes fractures without other ossicle problems are rare and ossicle problems due to explosion pressure are also rare. We describe a very rare case of stapes anterior crural fracture resulting from a land mine explosion. As this case suggests, a close examination of the ossicles is necessary during an exploration tympanotomy.

With the development of industrial technology, dust explosion accidents have increased, causing serious losses of people's lives and property. With the development of economy, we should lay further emphasis on causation, prevention, and treatment of dust explosion. This article summarizes the background, mechanism, prevention, and treatment of dust explosion, which may provide some professional knowledge and reference for the treatment of dust explosion.

Explosion has become one of the most common causes of death of the combat casualties. I made a comment on one case of autopsy whose cause of death was the accidental denotation of a 355 g rifle grenade and reviewed the clinical approaches and strategies of the blast injury.

Exploding head syndrome (EHS) is characterized by a sudden loud imagined noise or sense of a violent explosion in the head occurring as the patient is falling asleep or waking during the night. EHS is classified as "other parasomnia" on the ICSD-2 (International Classification of Sleep Disorders), and the neurophysiologic mechanisms underlying this hypnagogic phenomenon are unknown. EHS is a rare type of other parasomnia that has not been reported in Korea. We report two cases of EHS that presented with typical clinical symptoms.

There has been an explosion of literature focusing on the role of regulatory T (Treg) cells in cancer immunity. It is becoming increasingly clear that Treg cells play an active and significant role in the progression of cancer, and have an important role in suppressing tumor-specific immunity. Thus, there is a clear rationale for developing clinical strategies to diminish their regulatory influences, with the ultimate goal of augmenting antitimor immunity. Therefore, manipulation of Treg cells represent new strategies for cancer treatment. In this Review, I will summarize and review the explosive recent studies demonstrating that Treg cells are increased in patients with malignancies and restoration of antitumor immunity in mice and humans by depletion or reduction of Treg cells. In addition, I will discuss both the prognostic value of Treg cells in tumor progression in tumor-bearing hosts and the rationale for strategies for therapeutic vaccination and immunotherapeutic targeting of Treg cells with drugs and microRNA.

Facial injury by firework is not rare, but there are few reports on oral firework explosion injury. The authors of this article present a case of an 18-year-old male with intraoral injury from a firework explosion with literature review.

The dental profession is currently experiencing a technology explosion. Processes are being replaced by modern, inexpensive, and precise techniques that can be used to solve complex restorative problems. Electrical discharge machining (DEM, known as spark erosion in Europe) is a nonconventional, industrial technique that has application in dentistry. EDM may be defined as a metal removal process using a series of sparks to erode material from a workpiece in a liquid medium under carefully controlled conditions. EDM is recently adopted in the dental laboratory to fabricate precision attachments, hybrid telescope crowns, Ti-ceramic crowns. EDM has also been used to achieve a passive precision metalto-metal fit between the substructure bar and the removable superstructure and to correct the fit of implant retained restorations. in this article, a brief history and explanation of EDM is discussed and a description of the use of this process for fabricating attachments and crowns or for correcting the fit of cast restorations is presented.
