An in-vivo study of the safety of copper-containing intrauterine devices in 3.0 Tesla magnetic resonance imaging.

Purpose: The aim of this study is to prospectively evaluate whether women with copper-containing intrauterine devices (Cu-IUD), currently listed as MR conditional, can safely undergo 3.0 Tesla (3 T) magnetic resonance imaging (MRI).

Methods: 73 women, age 18-54 years old, with a Cu-IUD who were undergoing MRI for any reason were included consecutively.

Hypolipidemia in a Special Operations Candidate: Case Report and Review of the Literature.

Background: A 19-year-old male military recruit who presented for a screening physical for US Naval Special Warfare Duty was found to have hypolipidemia. Medical history revealed mildly increased frequency of bowel movements, but was otherwise unremarkable. His presentation was most consistent with heterozygous familial hypobetalipoproteinemia (FHBL), and the patient was cleared for Special Operations duty.

Recurrent, pruritic papules on the legs.

We present a patient with recurrent, pruritic, erythematous papules to the legs.

Erythema nodosum.

An active duty female Sailor reports to your clinic complaining of tender nodules to her legs beginning 1.5 weeks ago. She is diagnosed with erythema nodosum (EN), a painful disorder of the subcutaneous fat that is usually self-limited but may be a clue to an additional underlying medical diagnosis.

Ketogenic diet for high partial pressure oxygen diving.

Introduction: A ketogenic diet (KD) may decrease central nervous system oxygen toxicity symptoms in divers, and in view of this implication a feasibility/ toxicity pilot study was performed to demonstrate tolerance of KD while performing normal diving profiles. The exact mechanism of neuroprotection from the KD remains unknown; however, evidence to support the efficacy of the KD in reducing seizures is present in epilepsy and oxygen toxicity studies, and may provide valuable insight in diving activities.

Methods: Three divers (two males and one female ages 32-45 with a history of deep diving and high pO2 exposure) on the KD made dives to varying depths in Hawaii using fully closed-circuit MK-15 and Inspiration rebreathers.
