I have no idea about the effects that depth/pressure would have on a person with Mondini's Dysplasia. There might be concerns about the inability to equalize. However, there are those who would feel strongly that this person should not dive when he reaches the appropriate age. There is the...

Hi ladaniel: Your history sounds as if you sustained middle ear barotrauma. You probably have fluid (blood and/or serum) in your middle ear with possibly some damage to your ear drum(s). Examination would be beneficial. Most ENT doctors are quite familiar with this problem, even though they...

It would be of interest if you would post your published references to manipulation of the neck in reduction of problems equalizing. I cannot find any studies (RCTs) in Medline or anywhere else that point to this benefit. On the contrary - there are numerous references to the dangers of...

Rick is right on the money! In guinea pigs exposed to 100-percent oxygen at ambient air pressure for 48 hours, fluid accumulated in the lungs (pulmonary edema) and the epithelial cells lining the alveolus and pulmonary capillaries were damaged. Here are some effects In humans breathing...

Nitrous oxide will cause an increase in size of any air-containing compartments in the body - and this includes nitrogen bubbles. It would be risky to use it after diving or after a diving injury. Nitrous oxide before diving would offer the risk of decreased alertness and ability to multitask...

A phone call to Glaxo reveals that Malarone is available in Singapore. The particulars about prescriptions, etc. will have to be worked out there.

Hello BBG: It's doubtful that pseudoehphdrine caused the need for a pace maker - more likely some other factor as you have suggested. As a matter of fact, Sudafed was studied in divers and found to be safe [no mention of arrhythmias] but caused an increase in heart rate. Depth caused a...

This just might be a beta-endorphin increase in the male diver. Why not the female? I just don't know! I've learned many years ago not to predict what happens to ladies. Anyway - here are some citations that show elevated endorphins in divers. It's not just pressure, either, as Dewey's...

Hello Soggy: I have nothing much to add to the excellent discussion by the other medical posters. However, the percutaneous shock wave lithotripsy is invasive - while the ESWL is not. You will need to alter your diving plans somewhat until your wound heals completely. As for the Detrol -...

One would think that diving would be OK after release to complete activity by your physician. Repetitive loading of the metatarsal area of the foot while finning would be the greatest consideration. Depth/pressure/diving per se probably should not place the fracture site at risk -...

Of course, DocVikingo is correct in pointing out that Pfiesteria piscicida does not cause what is known as 'red tide', but is a more deadly relative of those organisms. (dinoflagellates) Other relatives of the organism are now suspected in the fish kills in Mobile Bay, South Carolina and in...

Hello Otter: Red tide is caused by Pfiesteria piscicida - which literally means "fish killer". It's effects on humans are no less dramatic - as described in Steven Barsky's book, "Diving in High Risk Environments", 8-10. "While Pfiesteria kills fish and other marine creatures, in humans...

I've had no personal experience but it is said to be a concoction of the same ingredients that protect the clownfish from being stung by the sea anemone. Here is the blurb about the product: "Scientists determined that a specific combination of glycosaminoglycans, magnesium and potassium...

Yours is probably the most frequent question that we get and the answer is most often in using the proper technique. Sometimes, however, there are real problems in the back of the nose that can be corrected. This can only be ascertained by a visit to a dive knowledgeable physician for...

Hello Diving Doctor: By far the best training in diving medicine that you can get would be with the military but this would require that you join the service. The Davis Hyperbaric Laboratory at Brooks AFB has the longest, continuously operating, hyperbaric medicine fellowship (true - - NOT...

A modified radical mastoidectomy is an operation for chronic ear disease that opens the ear canal to the mastoid cavity by removing the posterior (back) wall of the ear canal. Typically, outer ear canal entrance is enlarged to facilitate cleaning of the cavity created by the mastoidectomy. It...

Most seasickness pills work by blunting the nerve input to the inner ear - thus reducing the false positional stimuli coming in. If pills help your situation, there probably is some component of vertigo - and this could then be related to pressure changes (alternobaric) associated with...
