Blue-fingered diver: case report.

Although Raynaud's phenomenon is a well-known consequence of exposure to cold, neither its incidence in recreational divers nor case reports in that population have been reported in the medical literature. We present a case report of the initial manifestation of primary Raynaud's phenomenon during a warm-water scuba dive. A healthy 18-year-old Caucasian male made four open-circuit compressed air scuba dives over two days in the Florida Keys to a maximum depth of 90 feet.

Evidence for -G Adaptation Observed with Wearable Biosensors During High Performance Jet Flight.

Introduction: Few studies have evaluated physiological responses to high acceleration forces during actual flight and to our knowledge no normative data has been acquired by technologies such as wearable biosensors during high performance jet aircraft operations.

Methods: In-flight physiological data from an FDA cleared portable triaxial accelerometer and bio-sensor were observed from five active duty F-18 pilots of the Naval Flight Demonstration Squadron (Blue Angels). Of the five pilots, three were formation pilots who flew lower G profiles and two were solo pilots who flew higher G profiles.

Aeromedical Risk Assessment of Pharmaceuticals Using Evidence-Based Medicine.

Background: Using concepts from evidence-based medicine, systems theory, and risk assessment, a standardized model was developed to accept or reject medications for use in flight. The model calculates the risk scores of medications, which can then be compared to an organization's acceptable risk tolerance.

Methods: Risk scores for each medication were established by summing the products of incidence rates and severity scores for all published side effects.

Spontaneous intracranial hypotension: trendelenberg just may be the answer.

Spontaneous intracranial hypotension may share some characteristics with the more common causes of headaches such as migraines or tension headaches, but its diagnosis and treatment is much more laborious and invasive. Here, the case of a 31-year-old man with multiple weeks of positional headaches is described. This symptom persisted following multiple blood patches, and progressed to worsening mental status, encephalopathy, and eventually obtundation with Glascow Coma Score less than 8.

Alcohol screening instruments and psychiatric evaluation outcomes in military aviation personnel.

Introduction: Alcohol-related disorders are the most prevalent psychiatric conditions in the aviation population. Efforts to effectively screen aviators for these disorders are continually sought, as underdiagnosis may negatively impact aviation safety. This study evaluates screening tools that have been validated in non-aviators in terms of their utility for aviator patients.

Atopic dermatitis: diagnosis, treatment, and aeromedical implications.

Over the past 30 yr, the prevalence of atopic dermatitis (AD) has increased significantly in the general population. Given this increased burden of disease, more AD will be seen in civilian and military aviators. This article reviews the clinical aspects of AD with a focus on the aeromedical implications of the disease.
