Patent Foramen Ovale Study at the Mayo Clinic

Filed under: Uncategorizedscubadoc @ 10:03 am

Dr. Omar Sanchez, cardiologist/diver from Buenos Aires sends us this recent abstract of an article in the Mayo Clinic Proceedings debunking the bunk about relating cerebrovascular ischemic events [CIE] with large patent foramen ovale. The article, “Population-Based Study of the Relationship Between Patent Foramen Ovale and Cerebrovascular Ischemic Events”, by a large group with the Department of Neurology at the Mayo Clinic has the following conclusions:

“Patent foramen ovale is not a risk factor for cryptogenic ischemic stroke or transient ischemic attack in the general population. The PFO’s importance in the genesis of cryptogenic CIE may have been overestimated in previous studies because of selective referral of cases and underascertainment of PFO among comparison groups of patients referred for echocardiography for clinical indications other than cryptogenic CIE.”

Mayo Clin Proc. 2006;81(5):602-608

Implications for divers with PFO are not readily apparent, but might explain the highly unpredictive nature of right to left shunts across a PFO in divers.

Under The Sea

By Barbara McDermott

“Awesome!” “Diving is like being in space. I can float in one spot, and swim wherever I want to go.” These enthusiastic sentiments are from disabled SCUBA divers.”

I expect there will be much more in the press soon-a large group of
adapted divers are meeting in Nassau June 1-5. I’ll be there as an
instructor who specializes in adaptive scuba, and there are some video and
print reporters attending as well. One of the sponsors of the event is
SSI’s Platinum Pro Foundation - you can see their article on the event by clicking the embedded link.

You may already know that mainstream certifying agencies are adding
adaptive scuba certifications to their programs, thanks primarily to the
long-term efforts of Gain Wong and the Adapted Scuba Association (Toronto,
Canada - 416-534-2527). SSI and YMCA have programs in place, and I hope to
see both PADI and CMAS make announcements soon.

Best regards,

World Communication Center Offers Free DAN Membership with Satellite Phone Rental

Filed under: Uncategorizedscubadoc @ 1:29 pm


Chandler, Ariz. World Communication Center(WCC),
a leading provider of global satellite voice and data communications, in
partnership with Divers Alert Network (DAN), will offer new divers free DAN memberships valued at $29 when they rent a 9505A Iridium satellite phone for one week or more through June 30, 2006

Current DAN members benefit from the rental of the same phone kit by receiving a $30 gift certificate to use toward the purchase of DAN merchandise.

The WCC rental program allows DAN members to rent satellite equipment at weekly rates and pay for minutes they use at a fraction of what most international phone calls cost. Additionally, WCC¹s rental phones come pre-programmed with a simple speed dial direct to DAN¹s emergency hotline. DAN’s medical staff is on call 24 hours a day, 365 days a year, to handle diving emergencies such as decompression sickness, arterial gas embolism, pulmonary barotrauma or other serious diving-related injuries. Each year, DAN answers more than 2,000 calls on its Diving Emergency Hotline from its members and divers.

WCC¹s satellite communications provide the ideal communications solution for divers who typically travel in areas where landlines and cellular service are not available both on land and offshore. In emergency situations, DAN members receive 24-hour TravelAssist benefits; up to $100,000 of evacuation assistance coverage; prescription and medical assistance; emergency messaging; and insurance claims assistance. Other membership benefits include pre-trip information; Alert Diver Magazine; the DAN Dive & Travel Medical Guide; and discounts on DAN dive and related products.

Sam Romey, WCC president, said WCC has always recognized the value of emergency satellite communications in the diving industry. ³Many divers already use WCC¹s equipment and services, but a DAN membership will provide them with valuable benefits to ensure their ongoing safety,² Romey said.

Tony Bacci, vice president of marketing and new business development at DAN, said DAN encourages divers to take advantage of this promotion so they can travel and dive while enjoying peace of mind.

DAN News - New Resuscitation Guidelines Will Require Reconfiguring AEDs

Filed under: Uncategorizedscubadoc @ 12:50 pm

DAN News
New Resuscitation Guidelines Will Require Reconfiguring AEDs
Last Updated: 5/9/06 1:52:25 PM

Some automated external defibrillators (AEDs) require updating, according to the American Heart Association/International Liaison Committee on Resuscitation. These changes are needed in order to remain consistent with recent changes to the Emergency Cardiac Care Guidelines.

To update the Philips FR2+ or Philips OnSite AED, which DAN sold between 2002 and 2005, visit the Philips website at the following the link: http://www.medical.philips.com/us/products/resuscitation/2005_Guidelines.html and selecting “Product Reconfiguring Information.”

Before making any changes, you must consult the physician who provides medical oversight for your AED. Most states and provinces require that all AEDs, including those available as over-the-counter models, have physician oversight. Owners of other AEDs should contact the manufacturers for more information.

ABSTRACT: The Joint Service General Purpose Mask (JSGPM) is the next generation chemical protective mask intended to replace the MCU-2 and M-40 series masks. Developmental testing and user assessment of the XM5O, a variant of the JSGPM, indicated that the XM5O lacked sufficient fogging mitigation1 and sweat reduction capabilities. Lens fogging and sweat accumulation in the mask degrade user confidence, impose a physiological burden upon the user, and can seriously degrade operational effectiveness. These performance shortcomings resulted in joint service concern,2 and design changes to the mask were made. In 2003, a field evaluation3 indicated that the sweat reduction issues had been resolved, but the evaluation was limited and did not challenge the XM5O’s ability to mitigate fogging.

IDENTIFIERS: ASDS(ADVANCED SEAL DELIVERY SYSTEM), EBS(EMERGENCY BREATHING SYSTEM) LIMITATIONCODE: 01 00 00
ABSTRACT: A modified emergency Breathing System full face mask was evaluated for use in the Advanced SEAL Delivery System trainer. The mask contained an oral-nasal cup and two spiral-wound plastic hoses on its inhalation and exhalation openings. Each hose was six feet long with an inside diameter of 1.25 inches and had six rectangular slots cut through the hose wall. The slots were approximately eight inches from one end of each hose. Testing was conducted in an unpressurized hyperbaric chamber that was well ventilated with air. Carbon dioxide (CO2) washout volume - averaged inspired CO2 - was calculated at a respiratory minute ventilation of 22.5 liters per minute (1.min(exp -1). The mask was ventilated with a mechanical breathing simulator. One hundred per cent CO2 was injected at 0.9 1.min(exp -2) into the breathing loop. Mean CO2 washout was determined for two configurations: normal, with both hoses positioned so that the slotted ends are near the mask; and reversed exhaust, with inhalation hose positioned with its slots near the mask and exhalation hose positioned with the slots away from the mask. By our normalizing for the actual end-tidal CO2 level, the volume-averaged CO2 in the normal configuration was 0.71% and 0.75% with the exhaust reversed. Carbon dioxide washout of the modified emergency breathing system mask with exhaust hose in either configuration is acceptable for use in the ASDS trainer.

Hyperbaric Rx of Interstitial Cystitis

Filed under: Uncategorizedscubadoc @ 11:06 am

Interstitial Cystitis is a painful and difficult to treat malady affecting the urinary bladder. Here is a report of efficacy from treatment with HBO.
Hyperbaric oxygen treatment of IC
http://www.medpagetoday.com/Surgery/Urology/tb/3419

Arndt Van Ophoven and his group from Muenster, Germany presented an interesting study of hyperbaric oxygen therapy for treatment of IC at the AUA meeting. (abs 278)

They reported results of a randomized, double-blind, sham controlled study of 21 patients with IC. Patients were randomized to 1.3 atmospheres or 2.4 atmospheres for 90 minutes and a total of 30 sessions. There were 2 dropouts in the active treatment group.

None of the control patients had benefit as per their global response assessments, but 8 of 12 active patients achieved benefit.

At one year of follow-up, 5 of the 12 patients still perceived benefit from the intervention. Pain and urgency seemed to improve more than absolute frequency.

3. Our Annual Scientific Meeting in Orlando. Thanks to many of you, we have exceeded our block of rooms at the Hilton at Disneyworld in Orlando. We have just over three weeks before activity begins for us so there’s still plenty of time for you who have not registered for the meeting to do so and to arrange for lodging. Even though the deadline for the reduced rate at our two hotels is past, I suggest that if you try to make reservations at either the Hilton or the Grosvenor and are told the blocked rooms are full, let Lisa know before you try other places and she may be able to work some “magic” for you. You can telephone Lisa at (410) 257-6606 Ext 104.

As all of you know our outgoing President and our incoming President pass the gavel in a symbolic gesture of passing the leadership of our Society from one to the other. This usually happens at the awards banquet, but this year it appears that there will be a passing of the gavel underwater. If arrangements can be made, it will take place in the Disney aquarium and Dr. Lin Weaver will pass the gavel to Dr. Bret Stolp. Donna Uguccioni from DAN is setting it up. We don’t know just when the dive will take place, but we will place an announcement on our board for such things at the meeting…check it if you would like to witness the dive. Passing the gavel underwater will make a great photo! I hope I can attend.

For those of you who will be attending the meeting, don’t forget that, in addition to three days of scientific presentations, we have two great pre-courses, another class on preparing for facility accreditation, a post course sponsored by ATMO, and a Medical-Legal post-course that addresses Medical Fitness to Dive and the Practice of Hyperbaric Medicine. Surely, you won’t want to miss these!

4. Forty Years of UHMS History. I am putting together a booklet that summarizes our forty years as a Society to pass to each of you who attend our 40th anniversary meeting next year in Maui. I have 36 pages of information so far, thanks to several who have contributed and to some of our old files. Dr. Weaver has asked our Past Presidents to provide a paragraph of what they deem as the most significant event during their term of office. I plan to take the paragraph and paste it beside their picture. Thus our Past Presidents will be highlighted in the booklet. I thing such is appropriate because it has been their leadership that has molded us into what we are as a Society…oh, sure, they didn’t do it alone, but if you remember your leadership classes, “Delegation is the first sign of good leadership.” Our Past Presidents were not only outstanding in their own right, they had good leadership qualities as well.

What I would like to get from any of you is this: If you know of a bit of history associated with our Society, whether serious or otherwise, please send it to me to include in this booklet. Normally, I identify the persons who wrote bits and pieces, but if you don’t want to be identified as the author, please let me know and I will list your input as “anonymous author.” Please send me your memories and anecdotes about the Society.

That’s it for now, members. I hope to see you in Orlando!
