For Immediate Release

Guardian’s Keep takes readers on a thrill ride, above and below the water

 

 

The third dive adventure novel in the Mike Scott series by Eric Douglas is now available.

 

 

In this story, Dr. Francesca DeMarco, a beautiful archeologist, is searching an underwater site on the Adriatic Coast of Italy. Chasing stories of a mysterious group of Guardians, she runs into roadblocks as someone is trying to keep her from discovering the truth. News photographer Mike Scott is sent to do a story on the project, but when he and Dr. DeMarco are nearly killed in the process he decides to help her discover who is behind the attacks.

 

 

To unlock the mystery of the Guardians, they have to overcome a group of delusional fanatics bent to stop them at any costs. If they are successful, they might just find a religious artifact lost when the Romans overran the Temple in Jerusalem. If not, they might be locked away in a tomb for the rest of their lives.

 

 

 

This is Douglas’s third dive adventure novel. His first novel was set at Sunset House on Grand Cayman and described dives off of Sunset Reef, including a dive with the Sunset House Mermaid. The second novel, Flooding Hollywood, takes place off the coast of southern California and Catalina Island.

 

 

 

Douglas began diving in 1990 and became a dive instructor in 1998. He is currently the Training Director for Divers Alert Network in Durham, North Carolina. Guardian’s Keep is now available.

During the past 80 years a number of theories about the pathogenesis of osteoradionecrosis (ORN) have been proposed, with consequent implications for its treatment. Until recently tissue hypoxia and its consequences were accepted as the primary cause, and this led to the use of hyperbaric oxygen (HBO) for both treatment and prevention of complications of radiotherapy in the head and neck. The benefit of HBO has not been validated. A new theory for the pathogenesis of ORN has proposed that damage to bone is caused by radiation-induced fibrosis. Cells in bone are damaged as a result of acute inflammation, free radicals, and the chronic activation of fibroblasts by a series of growth factors. New treatments have therefore been devised that include pentoxifylline, a vasodilator that also inhibits fibrosis, and tocopherol (vitamin E) to reduce damage caused by free radicals. Impressive results in terms of reversing the process of ONR have been reported using these agents. It has been suggested that this theory and these agents could be the basis of future treatment and prevention of ORN.

INTRODUCTION: Ingestion of a small amount of concentrated hydrogen peroxide can cause cerebral air gas embolism (CAGE). Hyperbaric oxygen therapy (HBOT) is the standard of care in the treatment of CAGE. We report a case of CAGE after accidental ingestion of 33%hydrogen peroxide treated with HBOT resulting in reversal of both the clinical and radiologic abnormalities. CASE REPORT: A 48 year-old male took two sips of 33% hydrogen peroxide. A short time later, he developed hematemesis, left sided hemiplegia, confusion, and left homonymous hemianopsia. Initial laboratory studies, chest x-ray, and brain CT were normal. MRI demonstrated areas of restricted diffusion and T2 hyper intensities in multiple vascular territories consistent with ischemia due to CAGE. Eighteen hours after arrival, the patient underwent HBOT at 3 atmospheres absolute (ATA) for 30 minutes and 2.5 ATA for 60 minutes with clinical improvement. Follow-up MRI at six months demonstrated resolution of the hyper intensities. DISCUSSION: A search of MEDLINE from 1950 to present revealed only two cases of CAGE from ingestion of concentrated hydrogen peroxide treated with HBOT. Both cases, similar to ours, had complete resolution of symptoms. Of the seven reported cases of CAGE from hydrogen peroxide that did not undergo HBOT, only in one patient was there a report of symptom resolution. CONCLUSION: Ingestion of even a small amount of concentrated hydrogen peroxide can result in cerebral air gas embolism. Hyperbaric oxygen therapy may be of benefit in reversing the symptoms and preventing permanent neurological impairment.

We report two cases of pneumatosis intestinalis and hepatic portal venous gas. The first case was in a 67-year-old woman who complained of strong right lower abdominal pain and high fever on the twelfth day after pancreatoduodenectomy (PD) with portal vein (PV) resection. Abdominal X-ray and computed tomography showed hepatic portal venous gas and pneumatosis intestinalis. The emergency laparotomy performed disclosed extensive necrosis of the bowel from the jejunum to the ascending colon. All necrotic parts of the bowel were resected and a jejunostomy was performed. The residual intact small intestine was 30 cm in length. Her postoperative course was stable. This is a rare complication after PD and cannot be cured by any other treatment but surgery. The second case was in a 45-year-old woman with the chief complaint of abdominal pain and constipation. She had a past history of chronic toluene inhalation. Abdominal X-ray and computed tomography also showed hepatic portal venous gas and pneumatosis intestinalis, as well as free air, but no physical examination or laboratory test results supported a diagnosis of bowel necrosis. Hyperbaric oxygen (HBO) therapy effectively controlled the symptoms and signs.

How to make a hospital-based wound center financially viable

How to make a hospital-based wound center financially viable: the Georgetown University Hospital model.

PUBLICATION COUNTRY- United States
LANGUAGE- English

As the medical need and expenditure for chronic wound care have increased markedly over the past decade, wound centers have grown exponentially throughout the country. They can be community-based or hospital-based, and in either case, can be run by the facility or by a national chain. The wound center’s viability is dependent on generated revenue, and its clinical effectiveness is based on a multidisciplinary approach to wound care. By incorporating the wound center into an existing hospital system, one can take advantage of the hospital’s resources to effectively treat the more complex patients. Additionally, by focusing on limb salvage, the hospital attracts the critical limb ischemia and other complex patients that often require inpatient admission. We examined the Georgetown University Hospital Center for Wound Healing performance over the first 6 years of operation. Since opening the wound center in 1999, the number of outpatient visits has doubled, the wound care inpatient census has doubled, and the operative cases have increased 3-fold. Because the outpatient segment of the wound center can at best cover its direct cost, it cannot financially justify its existence. Hyperbaric oxygen (HBO) can increase the revenue to the point where the indirect costs are covered as well and the wound center can be revenue neutral. Due to the medical complexity of limb salvage patients, the inpatient collections are much higher than those of the outpatient wound center and therefore can serve as justification for the latter’s financial viability. More importantly, with the wound center in place, the hospital can provide the local/regional community with a comprehensive service that can effectively treat the most challenging wounds. The success is built on a multidisciplinary team approach, use of evidence-based treatment protocols, efficient clinical structure, and a supportive hospital system. The beneficiaries include the patient with a healed wound, the physician with a gratifying practice, the health care system with lower costs, and the hospital with a steady influx of complex patients.

The U.S.S. Oriskany in Pensacola, Florida: It’s a great wreck dive, though a bit deep for sport divers. The flight deck is at 135 feet — or it was, that is. But after Hurricane Gustav pushed through the Gulf of Mexico, the sunken ship dropped about 10 feet deeper. Now dive operators are worried that the drop to 145 feet will give pause to divers wanting to stay within the 130 foot “safe diving limits.” On the other hand, some believe the wreck will be safer because fewer people will be tempted to drop 15 feet past 130 just to touch the flight deck.

Hyperbaric chamber to study traumatic-brain-injury treatment

Hyperbaric chamber to study traumatic-brain-injury treatment

 


by Master Sgt. Kimberly A. Yearyean-Siers
59th Medical Wing Public Affairs

11/7/2008 - SAN ANTONIO (AFNS)  – The San Antonio Military Medical Center Hyperbaric Center and the Air Force School of Aerospace Medicine received funding to study the effects of hyperbaric oxygen therapy on mild to moderate traumatic brain injuries.

The study hopes to find additional ways to treat wounded warriors with traumatic brain injuries using the hyperbaric center, located at Wilford Hall Medical Center, or SAMMC-South, at Lackland Air Force Base, Texas.

Traumatic brain injury is common with head injuries caused by blows to the head, nearby explosions, concussion or penetrating wounds. These types of injuries have become relatively common in U.S. military forces who have served in Iraq and Afghanistan. Treatment of traumatic brain injury normally relies on traditional rehabilitative and retraining strategies or on the use of drugs to reduce symptoms, such as depression and anxiety.

The Air Force study will try to determine if hyperbaric oxygen therapy improves the cognitive function of individuals who have had traumatic brain injury. Cognitive function includes such things as thinking, remembering, recognition, concentration ability and perception.

Oxygen is a vital component in the body’s healing process. Hyperbaric oxygen therapy uses a combination of increasing the atmospheric pressure and 100 percent oxygen to dissolve oxygen into the blood plasma and deliver it to body cells, tissues and fluids up to ten times the normal concentration. This reestablishes oxygen to body tissues that are compromised or have been receiving less than normal amounts of blood flow and promotes healing.

“We hope that hyperbaric oxygen therapy will stimulate the area around injured brain tissue to improve the patients’ cognitive functions,” said Dr. E. George Wolf, a staff physician in the SAMMC Hyperbaric Center. “We will also monitor symptoms of post traumatic stress disorder to see if there are any changes during the HBO study.” 

Many patients are suffering from post traumatic stress disorder and traumatic brain injury and have symptoms of both, Dr. Wolf said.

The study will be conducted using 50 subjects who have been identified by their neurologists as having cognitive function problems and is scheduled to start in November. Potential subjects may be identified through neurologists at the Audie Murphy Veterans Hospital in San Antonio and SAMMC-North, or Brooke Army Medical Center at Fort Sam Houston, Texas.

According to a report prepared for Congress, more than 8,000 American military members currently suffer from some sort of brain injury as a result of the war on terrorism.

“It would be a great accomplishment if our study provides evidence that hyperbaric therapy can help these warfighters so they can be offered another opportunity to recover from their injuries,” Dr. Wolf said.

Lone Diver Rescued After a Night in Fiji Waters: There has been nearly a dozen incidents this year of divers getting lost at sea. This time, it was in Fiji, where Thomas Holz, 40, of Berlin, Germany spent 12 hours battling currents in the Somosomo Strait overnight and swam six miles before reaching land. On October 26, Holz and three other divers went with Bubble Divers for a late-afternoon dive on Rainbow Reef at Vanua Levu. Running out of air after 25 minutes, he ascended at about 5 p.m. The divemaster told him to wait at the surface while he fetched other divers below but currents were too strong for Holz to reach the boat 100 feet away, then nightfall prevented him from seeing it. The dive boat searched until 9 p.m., then resumed in the morning. Holz told the Fiji Times that he held onto his tank and swam slowly, skipping Vanua Levu for fear he’d wash up in an isolated place and aiming for more populated, although farther away, Taveuni. “In the early morning, I felt the seabed and screamed out for help before I collapsed on the shore.” More about this in our January issue.

Cayman’s Pummeled by Hurricane Paloma Saturday, Nov 8: On Cayman Brac, politician Juliana O’Connor-Connolly, described extensive damage to the majority of homes, businesses and churches. In many areas of the island, the water was knee deep. Diving legend Bob Soto, said “This is the worst hurricane I have ever seen …There is not one leaf left on the trees on The Bluff.” On Little Cayman early reports are that more than a dozen homes lost their roofs and one apartment complex caved in completely. While scores of people had to be rescued, nobody died on any of the islands. Grand Cayman had little damage or flooding. Supply boats are on their way to the sister islands. There is no word yet on dive resorts on the sister islands, but if you have travel plans make contact with your resort before you go.

Turks and Caicos’ Hurricane Ike Update: Mitch Rolling, who owns Blue Water Divers on Grand Turk, has told us that, “All three dive shops are completely operational, many dive boats received no damage at all. We have all had divers in since the storm, and the wall is in great shape . . . As for hotels, the Osprey Beach Hotel’s beach rooms never closed (they have their own big in-house generator) and fortunately were not damaged. The Osprey Beach bar and restaurant is fully open . . .The Salt Raker was damaged, and has not been open since . . . Manta House, right next door to Salt Raker, was not damaged badly, and is open. The Bohio on Pillory Beach lost the roof on its rooms. They are closed, but repairs are underway. . . .There are several local restaurants open and serving food. Obviously, there is still a great deal of cleanup work that needs to be done but a tremendous amount has been achieved already. We are grateful for the many sources who have already provided much assistance. . . .There is no reason why a diver or visitor can’t come to Grand Turk and enjoy a nice holiday.” Rolling’s comments about Salt Caye : “We are quickly getting back on our feet and all businesses will be operational by December 1. The dive shop is open now and some of the private homes are open for rentals. Tradewinds won’t be open till mid-November but will be newly remodeled, thanks or no thanks to Ike. Fortunately, there was little wave action, so very little damage to the reef.” Provo had little, if any, damage and hardly missed a beat after the blow.

The Underwater iPod: We’re all for communing with nature during a dive, but for those who get bored during decompression stops, there’s the iDive 300. Put your iPod in the waterproof case, good down to 300 feet, attach the over-the-ear speakers to your mask strap or under your hood, and watch movies or listen to music while you’re making the way to the surface. List price is $350. www.h2oaudio.com/shop/product.php?productid=63

Update on the U.S.S. Kittiwake: In last month’s e-mail newsletter, we announced the Cayman Islands had plans to sink this decommissioned U.S. Navy ship as an artificial reef. The Department of Tourism, recognizing that development has killed many of the reefs off Grand Cayman’s Seven Mile Beach, has announced that the Kittiwake will be sunk in June 2009 at the northern end of Seven Mile Beach. Gotta satisfy the divers who don’t want to head off to better Cayman diving.

The Oriskany Has Become a Deeper Dive

Filed under: Article, Newsscubadoc @ 12:03 pm

The sunken aircraft carrier Oriskany off the west Florida coast near Pensacola has descended about ten feet deeper due to the effect of recent hurricanes. This has made reaching the flight deck much more risky than before. An article about this in the Pensacola newspaper can be seen at http://www.pnj.com/article/20081105/NEWS01/811050340 .
