New Orleans Physician To Study HBOT For Traumatic Brain Injury

Filed under: Newsscubadoc @ 12:58 pm

A New Orleans, Louisiana emergency medical physician has started a study using Hyperbaric Oxygen treatment therapy at LSU Health Sciences Center. The study involves veterans who have suffered TBI with or without PTSD. Several veterans who are participating are reporting amazing results according to a news story released on WWL-TV on Wednesday. Dr. Paul Harch, the medical researcher leading the pilot study, says simple unconsciousness from a head injury causes the loss of brain cells because of a lack of oxygen to the brain. Hyperbaric Oxygen treatment may help heal brain damage. The study is open to victims who have suffered a TBI from a blast or an explosion and military personnel are encouraged to participate. Blast injuries have been the number one most common cause of TBI and PTSD among veterans of the Iraq and Afghan wars.

New Study Supports Closure of PFO for Migraine Sufferers

Filed under: News, Publicationscubadoc @ 11:04 am

It has been observed that by closing PFO migraine sufferers are benefited by a reduction in the headache severity. Reducing the frequency and severity of disabling migraines is crucial for quality of life. A new study, published in the February 2009 issue of JACC: Cardiovascular Interventions, finds significant improvement of migraine following catheter-based closure of patent foramen ovale (PFO)—a slight opening in the wall between the right and left atria.

The present study was the first to enroll patients with severe migraine, a large PFO and no history of stroke or transient ischemic attacks, but with silent brain lesions on magnetic resonance imaging.

“The study suggests closure of a large PFO may improve migraine in patients with subclinical brain lesions, as well as those with prior stroke,” says Carlo Vigna, M.D., of Casa Sollievo della Sofferenza IRCCS Hospital, San Giovanni Rotondo, Italy. “In the past, the beneficial effect on migraine was occasionally seen after PFO closure was performed for other reasons, for example, unexplained stroke. Conversely, the recently published MIST trial did not show significant improvement of symptoms in ‘pure migraneurs’ in the absence of symptomatic or subclinical cerebral ischemia. As compared with these two extremes, we enrolled patients with an intermediate subset of characteristics.”

Patients were divided into either the closure (n=53) or control (n=29) group based on their consent to undergo percutaneous PFO closure, and prospectively examined for 6 months. Compared with the medically treated control group, closure of a PFO resulted in greater numbers of patients who had cessation of migraine attacks, cessation of disabling attacks and over 50 percent reduction in migraine attacks.

While this may be good news for certain migraine sufferers, researchers say a larger randomized trial focusing on this patient population is needed. In addition, the relationship between PFO and migraine must be further examined and understood.

“We don’t really know what’s going on. A stroke could be caused if a blood clot passes across a PFO and travels to the brain, but with migraine we don’t yet know what the trigger substance is that crosses the shunt,” says Dr. Peter Wilmshurst, Royal Shrewsbury Hospital, United Kingdom. “Not everyone with migraine has a PFO, and not everyone with a PFO has migraine; there are other causes that we don’t yet understand.”

Background: It is widely accepted that migraine is associated with higher rates of stroke. Research also suggests that people with migraine also have a higher prevalence of right-to-left shunts on contrast echocardiograms, which are, by and large, due to PFO—something each of us has while in the womb to divert blood away from the lungs. However, for one in four people, a hole remains after birth.

Florida Diver Loses Both Legs to Speedboat: While surfacing from a dive in the St. Lucie Inlet on January 9, Rob Murphy, 26, was struck by a passing boat, which severed both his legs. The boat was operated by Roger Nicosia, ironically an emergency room physician. Murphy, who lost nearly half his blood, was spared from death because his dive buddies acted quickly and applied a tourniquet before the helicopter ride to the hospital. Even though doctors couldn’t save his legs, Roberts told the Treasure Coast News he is “trying to make a sad situation into a positive.” Now he is doing physical therapy and intends to dive again one day. On January 31, volunteers at boat ramps around Florida talked to boaters and anglers about dive flag safety laws, and also carried a petition to create an official state “Dive Flag Awareness Day” that they intend to present to the governor.

The Great Stingray Migration: It’s that time of the year when golden cownose rays amass for the spring leg of a Caribbean migration. Amateur photographer Sandra Critelli took some amazing photos of rays moving from Isla Holbox in Mexico’s Yucatan peninsula, following the clockwise current to western Florida (see her photos here:–thousands-majestic-stingrays-swim-new-seas.html) Golden cownose rays migrate in groups of up to 10,000, heading north in the spring and returning in late autumn.

One Diver Pleads Guilty in “Operation Freezer Burn”: John R. Niles, a 50-year-old house painter from LaBelle, Florida admitted in court on January 21 that he was one of six divers who illegally harvested more than 1,100 lobsters from the Florida Keys National Marine Sanctuary last August. The other defendants include two charter fishing captains, Rob Hammer of Miami and Mike Delph of Key West. After watching the six divers place artificial habitats in the water, then dive down to harvest lobsters from the sites, federal agents made their arrest on opening day of lobster season last year. The defendants allegedly stored the illegal catch in underwater cages to sell them later. Niles is free on bond and will be sentenced on April 2; he could get up to five years in prison and a $250,000 fine.

Bahamas Creates Marine Reserve in North Bimini: The government announced the decision in mid-January to create the reserve that’s home to mangrove habitat, the Nassau grouper and lemon sharks. The decision is a setback for the Bimini Bay Resort and Marina, which had been clearing some of the mangroves to build a hotel, a golf course, a casino and two marinas. A scientific paper last year showed that the resort’s dredging had cut the first-year survival rates of juvenile lemon sharks there by more than 23 percent. Most fishing is prohibited in the new reserve, except for traditional land crabbing and limited catch-and-release bonefish fishing.

Was Sean Connery A Good Diver?: The James Bond-focused website MI6 has an interesting two-part interview with Jordan Klein, the underwater engineer for Thunderball, Live and Let Die and Never Say Never Again.

Air Embolism Via PFO from venous catheter, HBOT

Filed under: Article, Publicationscubadoc @ 10:31 am

J Intensive Care Med. 2008 May-Jun;23(3):204-9.

Paradoxical air embolism successfully treated with hyperbaric oxygen.

Scruggs JE, Joffe A, Wood KE.

Section of Pulmonary/Critical Care Medicine, University of Wisconsin Hospital and Clinics, Madison, Wisconsin 53792, USA.

The use of the central venous catheter may be complicated by air embolism when central venous pressure is subatmospheric and the catheter is open to the surrounding air. Paradoxical air embolus occurs when the gas bubbles are able to traverse a right to left shunt, gaining access to the systemic arterial circulation causing ischemic symptoms in end organs. In this article, a case of a patient with an unknown patent foramen ovale through which air entered the arterial circulation resulting in obtundation and stroke after inadvertent manipulation of a Hickman catheter is presented. The physiology, clinical manifestations, and management strategies are also discussed.
