The Surgeon's Role in Disaster and Counterterrorism Medicine.

Medical and surgical care remain a critical feature of disaster preparedness. The evolution of modern warfare introduces elements manifesting as both domestic and foreign terrorism. The fields of disaster and counterterrorism medicine continue to evolve in response to these looming threats.

The Evolution of Disaster and Counterterrorism Medicine-An Introduction.

The specialties of disaster and counterterrorism medicine have continued to evolve based on the demand for medical responses to these unique and demanding environments. These medical responses are relevant to all medical specialties; however, surgeons play a particularly critical role. This is evidenced from decades of humanitarian and military surgical involvement.

Low-Cost Model for Battlefield Wound and Hemorrhage Training.

Introduction: Exsanguination is the leading cause of preventable death on the battlefield and in austere environments. Multiple courses have been developed to save lives by stopping hemorrhage. Training for this requires simulation models; however, many models are expensive, preventing the further expansion of this life-saving training.

Reconstruction of Large Transmural Nasal Defects With a Nasolabial Turnover Interpolation Flap.

Background: Reconstruction of large nasal surgical defects often warrant the use of mucosal flaps to repair the inner lining. This often presents a challenge for surgical reconstruction.

Objective: To describe a unique reconstructive option for the repair of large surgical wounds that necessitate mucosal nasal lining.

Clinical Features of Scleritis Across the Asia-Pacific Region.

: To examine the spectrum of scleritis in four tertiary institutions across the Asia-Pacific. : Clinical records from 354 patients were reviewed from centers in Australia, Singapore, and India, excluding those with insufficient data ( = 24). : Indian patients presented younger (41.

Laboratory evolution of artificially expanded DNA gives redesignable aptamers that target the toxic form of anthrax protective antigen.

Reported here is a laboratory in vitro evolution (LIVE) experiment based on an artificially expanded genetic information system (AEGIS). This experiment delivers the first example of an AEGIS aptamer that binds to an isolated protein target, the first whose structural contact with its target has been outlined and the first to inhibit biologically important activities of its target, the protective antigen from Bacillus anthracis We show how rational design based on secondary structure predictions can also direct the use of AEGIS to improve the stability and binding of the aptamer to its target. The final aptamer has a dissociation constant of ∼35 nM.

Bioterrorism and disaster preparedness among medical specialties.

Objective: A core priority of all medical specialties includes information for members regarding inherent priorities and principles. The authors sought to investigate the priority and contribution of various medical specialties to the fields of bioterrorism, terrorism, disaster preparedness, and emergency preparedness.

Design: A mixed study design (quantitative and qualitative) was used to identify pertinent characteristics of various medical specialties.

Perineural involvement of squamous cell carcinoma presenting with formication.

Perineural involvement of a cutaneous neoplasm marks an aggressive feature. Tumors with perineural involvement share an increased propensity for local invasion via perineural spread. Formication may be an indicator of perineural involvement by cutaneous neoplasms.

Self-induced nasal ulceration from trigeminal trophic syndrome.

Trigeminal trophic syndrome is a rare entity characterized by the presence of ala nasi ulceration, trigeminal anesthesia, and paresthesia. It arises secondary to trigeminal nerve injury. Patients with this diagnosis often undergo repeated skin biopsies to rule out suspected nonmelanoma skin cancer due to the clinical appearance.
