Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso.
Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso.
Shingles is caused by the varicella-zoster virus β the same virus that causes chickenpox. After you’ve had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles.
Shingles isn’t a life-threatening condition, but it can be very painful. Vaccines can help reduce the risk of shingles. Early treatment can help shorten a shingles infection and lessen the chance of complications. The most common complication is postherpetic neuralgia, which causes shingles pain for a long time after your blisters have cleared.
More than 55 million people worldwide are living with dementia, a neurological disorder that robs them of their memory and costs the world $1.3 trillion a year, the World Health Organization (WHO) said on Thursday.
COMMENTARY:
Preventing Dementia by healthful living habits such as good sleep, diet and exercise would certainly save lots of misery and expense, by preventing dementia. These same habits would also go a long way in preventing auto immune disease, diabetes and chronic stress.
Type 1 and type 2 diabetes are characterized by increased blood glucose levels. They affect almost half a billion people around the globe, and this number is projected to rise as we reach the middle of the century. In most individuals, blood glucose levels are kept within a healthy range by a hormone called insulin, which is secreted by the pancreas, but this fine-tuned regulation can go wrong in type 1 and type 2 diabetes. In this animation, we lay out our current understanding of these diseases and explore active areas of research that aim to restore the bodyβs blood glucose control.
When not walking barefoot at night or on the beach, my toes have been squeezed together most of my life. Closed-toe compression stockings for my varicose veins plus inadequate space at the front of my shoes have encouraged my big toe to βscissorβ and to cross over the second toe. At that point I started wearing open-toe stockings, and tried to give my toes more room in larger shoes. I also used a spacer to push the big toe out.
Walking on the beach is a wonderful place to free up your toes. For a while, I walked in the deep sand at the top of the beach, trying to get more exercise. Periodically I would get some thorns in my feet, and go to podiatrist to get them out.
During one visit, the podiatrist told me that I was getting a hammer toe in the toe right next to my big toe, and I now use a little ring shaped cushion for that second toe, incorporated with a spacer.
It is amazing how little we use the musculature of our feet, and how surprisingly well they hold up. People that are really in good athletic shape stress flexibility as being very important, and athletes often do stretching exercises before they do their workout. Practically anything that will stretch a joint is helpful, such as flexing, extending, and spreading the toes, plus flexing and extending the foot.
You can overdo it, however, as I have learned to my discomfort. You must do any exercise within the limitations of your body, beginning slowly, and working up to your desired level.
My big toe has almost no flexibility, and the joint that attaches it to the foot is enlarged and pretty fixed. I am very careful how much range and pressure I use .Even something as simple as stretching the Achilles tendon can be a problem if you do too much of it all at once. Always work slowly into your exercises to make sure that you do no harm.
Ingrown toenails have also bothered me from time to time. I very carefully try to trim them back and avoid breaking the skin; the foot is easily infected, particularly among diabetics and older people. A podiatrist is very helpful if you let things go too far.
My toenails, particularly on my big toe, are getting white and thick with a nail fungus. This can be treated with an oral medication, dispensed by a doctor or a podiatrist. I have chosen to keep it in check with clotrimazole cream, and that seems to be working. I worry from time to time about creating a resistance factor in the fungus, but they are very slow growing, and not likely to develop a mutation.

In a very good article, the Journal ‘Science’ has collated a lot of basic science regarding aerosol transmissions in viral infection generally, and Covid-19 in particular.
Early in the epidemic, I thought that large droplet transmission, which fell to the floor, and was transmitted by fomites and hand autoinoculation into the respiratory membranes, was more important. The main thesis of the article is that it is not large droplets, but aerosol particles that mainly transmit.
The secondary assertion is that aerosols can be up to 100 Β΅m microns in diameter and still be transmitted by inhalation. they also stated that particle size of equal or less than 5 Β΅m contain more virus particles than all the larger particles put together in spite of the greater mass of the larger particles . Normal speaking creates about 1000 aerosol particles per minute, And normal breathing about 7200 aerosol particles per liter of exhaledΒ air. Coughing is more sporadic and tends to produce the larger droplets which donβt stay airborne as long, but I wouldnβt count on it.Β Β
There is a tremendous difference between individuals as to the number of particles they generate. Itβs estimated that 10 to 20% of individuals account for 80 to 90% of the virus.
Slide number twoΒ deals with viral load and infectivity which is a function of the pH value, electrical charge, and other characteristics of the virus. An important point is that even though there is lots of viral RNA, that doesnβt mean that the virus is infective. Once again thereβs a tremendous difference between the infective viable virus content of the aerosols from infected patient to patient. He stated that in one room with two Covid patients, they were 6 to 74 TCID/50 per liter, which means youβre almost certain to be infected if you donβt have a mask that filters out the virus, or some kind of purification in the room.
Slide Three was very interesting to me. The persistenceΒ in hours graphed against the aerosol particles size. 100 Β΅m particles stay in the air only about five seconds, 5 Β΅m particles stay in the air for 30 minutes, and one micrometer particles will stay in the air for 12 hours or more.
The fourth slide talks about factors affecting the distribution of indoor aerosols. There may be certain parts of the room where the particles congregate , depending on the ventilation type, whether natural, mechanical or filtered, flow patterns within the room, and indoor filtration and killing devices such as ultraviolet light.
Mention is made of the CO2 level in the room as a measure of air circulation. There is a higher CO2 in the air with lots of people and poor ventilation. The recommendation is that 7-8 ppm is about the highest acceptable level, and the possibility of using a portable HEPA filter would not be a bad idea for people frequenting indoor restaurants. Of course, outdoor air with its breezes, dispersion, less humidity, higher ultraviolet and usually Greater dispersion of people is preferable to indoor contact.
Some other interesting points are that children produce less aerosol particles because they have a smaller number of bronchi. I thought the bacteria were less likely to be aerosol transmitted than viruses, but they state that the R0 of tuberculosis can be as high as 4.3, vs. 7-8 for covid. The typical tuberculosis bacillus is relatively large, and yet is only 2 Β΅m in length, well within the size of an aerosol particle.
There are many types of cells in the human body, and any of them can mutate, and become cancerous.Β Cells of The immune system are no exception, ironically,Β even though their one of their jobs is to fight cancer.
The plasma cell is an immune system cell that develops from lymphocytes(B-cells) and specializes in producing βGamma Globulinsβ, a type of antibody.
When cancer involves plasma cells In the bone marrow it tends to crowd out the other cells. This can produce bone pain and anemia.
All of the cancer cells come from a single progenitor cell and form a βcloneβ. This clone produces a large amount of defective protein that would normally be combined with other proteins into the making of antibodies. The large amount of the same protein can often beΒ detected in the urine, as a βBence Jonesβ protein.
In modern terminology, the condition is called a βmonoclonal gammopathyβ. This mass of protein gets into the bloodstream, and can deposit in various tissues, where it is called βamyloidosisβ. The kidneys are often damaged in the process of excreting the overproduced, repetitious chains of useless protein.
I had a friend who was a pilot in the military during the Vietnam war. He was around βagent orangeβ,Β which was on the news a lot in the 80βs. Agent orange was contaminated by a toxic chemical called Dioxin, which is known to cause cancer. My friend developed a cancer, primary amyloidosis, which is a close relative of multiple myeloma, and in his case produces what is called light chains.
His first warning was an elevated creatinine on a metabolic panel blood test, which pointed to the kidneys.Β Medical investigation uncovered his plasma cell cancer, and he began treatment.Β His kidneys eventually started to fail.
His daughter donated one of her kidneys, and currently heβs doing well, since medical treatment curtailed the light chain production. Please refer to the accompanying Cancer association article on multiple myeloma.

In the video above, Alexander Stockton, a producer on the Opinion Video team, explores two of the main reasons the number of Covid cases is soaring once again in the United States: vaccine hesitancy and refusal.
βItβs hard to watch the pandemic drag on as Americans refuse the vaccine in the name of freedom,β he says. Seeking understanding, Mr. Stockton travels to Mountain Home, Ark., in the Ozarks, a region with galloping contagion and β not unrelated β abysmal vaccination rates. He finds that a range of feelings and beliefs underpins the low rates β including fear, skepticism and a libertarian strain of defiance.
This doubt even extends to the staff at a regional hospital, where about half of the medical personnel are not vaccinated β even while the intensive care unit is crowded with unvaccinated Covid patients fighting for their lives. Mountain Home β like the United States as a whole β is caught in a tug of war between private liberty and public health. But Mr. Stockton suggests that unless government upholds its duty to protect Americans, keeping the common good in mind, this may be a battle with no end.
COMMENTARY:
I am a Doctor Who has studied the miracle of MRNA Covid vaccine, and who knows that it cannot get into the nucleus of any of my cells or long remain in my body.
I have studied the transmission and pathogenesis of Covid, and know how it works. The knowledge that it could affect my thinking, memory, my very essence, and the fact that it could last indefinitely after the initial illness has certainly made me a believer.
There is an element of truth in the concerns of anti-vaxers and anti-maskers. Unfortunately the problem is not black and white. No vaccine is 100% safe, although the mRNA vaccines come close. There is some worry about clotting problems with a few people, particularly the young. This risk is measured in terms of problems per million people getting the vaccine, and is vanishingly small compared to the alternative of exposing yourself to the ravages of Covid.
An intelligent friend of mine who is a nurse has auto immune disease, and vaccines tend to hit her hard. Unfortunately the fact that she is a nurse and is exposed a lot to the public make her more likely to get Covid, and her auto immunity would render her much more likely to have complications, should she get it. She has received her first injection of Covid vaccine, and had a lot of fatigue, headaches and symptoms that were relatively self-limited.
Masks are mainly useful in protecting other people from the mask-wearer and only slightly helpful in protecting the mask wearer from other people. Also, I have read a long article about some subtle disadvantages of forcing children to wear masks although I think itβs still a good idea, particularly when Covid is common in the community.
The main problem is that Americans have freedom of choice without the knowledge to weigh the benefits and hazards of receiving the vaccine, versus the hazards of getting the disease.
There are times when we should unload the making of such statistical decisions on people who know more about the vagaries of disease. In my opinion, the states which allow hospitals to require their healthcare workers to receive vaccination, and allow schools to require their students and teachers to receive vaccination are in the right. Currently, there are less problems in those states.
Covid is certainly a nasty disease, and even doubly vaccinated people can be spreaders. As an elderly vaccinated person, I still treat everybody as if they are infected, and require masks when visitors come. When inside, I sit by an open door, with a fan behind me blowing air in the other direction.
At the age of 89, I cannot afford to get Covid-19.
