Patient discussion about sensitizer

Q. I had cataract surgery with iol implant, and ever since I have awful light sensitivity. Any ideas? I can't go into a "super store" without my sunglasses. My eyes ache at the end of the day. My doctor says "I don't know!"

A. May sound a bit silly question, but have you tried to consult your ophthalmologist (eye doctor, e.g. the one that performed the operation) about it? Cataract surgery, although considered very successful, isn't problem-free. Primary physician may not have the necessary specialization to deal with these subjects.

Q. I heard that patients are highly sensitive to their senses? what are the most common symptoms of fibromyalgia and can they be aggravated? I heard that patients are highly sensitive to their senses?

A. Great answeer...couldn't agree more!

Q. when my aunt went through chemo (for colon cancer) her palms became VERY sensitive and had a burning feeling is there any way to prevent this from happening to my mom who is starting her chemo now? If not, what it the best treatment for it?

A. What you describe sounds like peripheral neuropathy, a well known side effect of platinum chemotherapy which is used for colon cancer. Several measures, including giving infusion of calcium and magnesium, and glutathione were found to reduce the rate of this complication, although further studies are necessary.

However, the information is only general advice, since I haven't examined your mother so if you have any questions about this subject, it may be wise to consult a doctor (e.g. oncologist).

Considerations in relation to the therapeutic use of light activated killing of biofilms on host surfaces include: (1) direct toxicity of the sensitizer, (2) indirect toxicity of the sensitizer in terms of 'bystander' damage to adjacent host cells, (3) penetration into the biofilm, (4) light exposure time required to kill bacteria within in vivo biofilms, and (5) widespread relatively non-specific bacterial killing.
In this study, we investigated the photobleaching of pyropheophorbide methyl ester (PPME) and pyropheophorbide a (PPa) in a homogeneous solution of dimethylformamide (DMF) during PDT and estimated whether fluorescence photobleaching of the sensitizer or the formation of its photoproduct is appropriate for evaluating PDT dose.
