spinal cord Decompression Sickness in sport diving
JAMA Neurology, 1993Co-Authors: Judith Aharonperetz, Yohai Adir, Carlos R Gordon, Shahar Kol, Nachum Gal, Y MelamedAbstract:• Objective. —To summarize 16 years' experience in the diagnosis and treatment of spinal cord Decompression Sickness in Israel. Design. —The survey data were collected firsthand by physicians trained in underwater diving medicine. Setting. —The Israeli Naval Medical Institute, Israel's national hyperbaric referral center. Patients. —Sixty-eight sport divers diagnosed as having spinal cord Decompression Sickness. Interventions. —Hydration and 100% oxygen breathing until the patient reached the hyperbaric chamber. All patients received recompression therapy on US Navy treatment tables using oxygen, except for six who were treated by Comex Treatment Table CX-30, which uses helium in addition to oxygen. Main Outcome Measures. —Neurological examination after the completion of recompression therapy. Results. —Forty-one percent of the dives were performed within the Decompression limits of the US Navy standard Decompression tables. Risk factors were fatigue, circumstances suggesting dehydration, and extreme physical effort. The most common presenting symptoms were paresthesias, weakness of the legs, lower back pain, or abdominal pain. Full recovery was achieved in 79% of the patients. Spinal symptoms appeared immediately on surfacing in six of the eight patients who continued to have multiple neurological sequelae. Conclusions. —United States Navy air Decompression tables appear not to be completely safe for sport divers. Even mild spinal symptoms identified on surfacing should be treated vigorously. High-pressure oxygen-helium therapy seems to be a promising alternative in cases of severe spinal cord Decompression Sickness.

Whales, sonar and Decompression Sickness (reply)
Nature, 2004Co-Authors: A. Fernández, M. Arbelo, R. Deaville, I. A. P. Patterson, P. Castro, J. R. Baker, E. Degollada, H. M. Ross, P. Herráez, A. M. PocknellAbstract:Jepson et al. reply — We did not, as Piantadosi and Thalmann suggest^ 1 , present our findings as conclusive evidence of Decompression Sickness (DCS). We stated neither that DCS occurs naturally in cetaceans, nor that exposure to active sonar increases its occurrence^ 2 . However, we restate that there is now a generally accepted link between some beaked-whale strandings and sonar use, and that lesions in some cetaceans demonstrate that in vivo bubble formation (embolus) can occur and persist.

Presumed Venous Infarction in Spinal Decompression Sickness
AJNR. American journal of neuroradiology, 1998Co-Authors: Yasuhiro Manabe, Kenichi Sakai, Kenichi Kashihara, Toshikiyo ShohmoriAbstract:We describe the serial MR imaging findings in a patient with spinal Decompression Sickness. In the acute phase, the spinal cord was swollen, with increased T2 signal in the posterior part of the column; 1 month later, marked contrast enhancement was noted in the same location; and 2 months later, the swelling and T2 signal had decreased. MR imaging may facilitate the early diagnosis of spinal Decompression Sickness.

recurrent inner ear Decompression Sickness associated with a patent foramen ovale
Archives of Otolaryngology-head & Neck Surgery, 2002Co-Authors: Christoph Klingmann, Michael Knauth, S Ries, Rolf Kern, Abeljan TasmanAbstract:Isolated inner ear injuries occurring during shallow scuba dives are an uncommon manifestation of Decompression Sickness in recreational divers. We describe a patient who presented with the typical symptoms of inner ear involvement after 2 independent dives within the Decompression limits. The diver reported symptoms of unilateral (right-sided) hearing loss, tinnitus, and vertigo after dives to 35 and 50 m. After treatment with hyperbaric oxygen, his symptoms completely resolved. To confirm the hypothesis of inner ear Decompression Sickness (IEDCS), we examined the patient for a right-to-left shunt by cranial Doppler ultrasound and found a patent foramen ovale. The existence of a patent foramen ovale is suspected to be a risk factor for developing neurological symptoms of Decompression Sickness. There was no evidence of any other risk factors, so we suggest that the relevant right-to-left shunt in our patient may have been the predisposing factor that caused the inner ear symptoms during his scuba dive.
