Dear Doctor: I'm 75 years old and am scheduled to have minor surgery next month. My doctor has been pushing me to walk every day and to perform core exercises -- not to mention eating right -- ahead of my operation. Does this really matter?

Dear Reader: Indeed, it does. Recent studies show that elderly patients are at increased risk for a range of complications during surgery and during the recovery process as well. But it's not just about age. By comparing pre-operative assessment data to how patients fare during surgery and recovery, researchers have been able to establish a definitive link between frailty and poor surgical outcomes. These range from complications during the procedure, slow or incomplete recovery afterward, and a net decline in health and cognition in the weeks and months after the surgery.

And younger readers, take note. This correlation turns out to hold true for patients of any age. In fact, the new thinking is that frailty is a more important indicator than chronological age when evaluating patients for elective surgery.

However, frailty, which is basically a reduction of the physical and mental reserves that help us bounce back from setbacks due to illness or injury, is far more common in older adults. Additional factors also make surgery more of a challenge for older adults. These include ongoing conditions or illnesses that place added stress on the body. Problems with vision, hearing or mobility have an effect on both surgery and recovery. A range of prescription medications can increase the risk of certain complications. And issues related to cognitive function, mood and social circumstances play a role in overall well-being.

The good news is that this new research has prompted the American College of Surgeons to launch a nationwide effort for hospitals, health care providers and patients to become aware of the unique challenges that elderly adults face when undergoing surgery and recovery, as well as the steps they can take to mitigate those risks. Supporting data comes from Duke University's Perioperative Optimization of Senior Health (POSH) program, an interdisciplinary team approach to helping older adults prepare for and recover from surgery. This program includes the very behaviors your physician is urging you to adopt.

In an assessment of elderly patients undergoing elective abdominal surgery, those from the POSH program had shorter hospital stays (four days for the POSH group versus six days for the control group) and lower readmission rates (7.8 percent vs. 18.3 percent) over the course of the month following surgery. They also experienced fewer complications and were more likely to be discharged to go home with self-care than were the patients in the control group, who had not taken part in the POSH program.

We hope that you'll take your physician's advice to heart and follow the recommended program. Not only can these behaviors increase the chances for a good outcome following your surgery, but continuing the fitness regimen of daily walks, core exercises and deep breathing after your recovery will improve your quality of life.

Common Adenovirus Has Many Subtypes

Dear Doctor: I've been hearing about adenovirus, which is often mistaken as the flu. How can you tell the difference? And is it as serious as the flu?

Dear Reader: Your question is a great reminder, especially during flu season, of how complex and ubiquitous viruses are. They cause a host of illnesses, with the common cold alone blamed on more than 200 identified subtypes of virus and many more that are still unidentified. One main group of viruses is adenovirus.

Adenovirus got its name because it was first isolated in the adenoids, although this isn't the only place it's found. More than 60 types of adenovirus exist, with some causing much different symptoms than others. Serotypes 3, 5, 7, 14 and 21, for example, have been associated with more severe disease.

Adenoviruses most commonly cause upper respiratory symptoms. These include inflammation of the throat, leading to a sore throat, and swelling of the membranes in the nose, leading to runny nose and nasal congestion. Such symptoms are often accompanied by headache, fever, fatigue, muscle pain and stomach pain.

But adenovirus can also lead to conjunctivitis, laryngitis, bronchitis and even pneumonia. Adenovirus-caused pneumonia more often affects those younger than 5 years old, accounting for 15 percent of pneumonias in this age group. Young children can also be affected by subtypes of adenovirus that lead to diarrhea, which can last up to eight to 12 days.

In rare cases, the virus can affect the brain, causing meningitis or encephalitis, or lead to inflammation of the liver and the heart muscle. In people with a compromised immune system or those who have had an organ transplant, adenovirus can lead to more severe disease and possible death.

Adenovirus is a resilient virus. It can survive for long periods on environmental surfaces and -- though bleach, formaldehyde and heat can inactivate it -- the virus is resistant to many disinfectants. It can be transmitted through respiratory droplets spread by sneezing, coughing or contact with secretions. Adenovirus is also shed in the stool for many weeks after an acute infection. Without proper handwashing by all parties, the virus can then be taken in orally by another individual.

Because adenovirus is easily transmissible, it's associated with outbreaks of infection in day care settings and among military recruits. In fact, military recruits are now vaccinated against adenovirus, which has decreased their rate of infection.

Adenovirus is diagnosed by either viral culture or by tests producing more rapid results. The treatment is similar to those for other cold viruses -- fluid intake, rest, acetaminophen or nonsteroidal anti-inflammatory drugs (aspirin, ibuprofen) for headache and medications for diarrhea. For people who are taking drugs to suppress the immune system, the antiviral medication cidofovir can improve survival.

Yes, many of the symptoms are similar to influenza, especially in young children. The fever in those under 5 with adenovirus averages 102.6 degrees. This is similar to influenza. However, influenza is a much deadlier virus, especially among older individuals, causing thousands of deaths per year. Although adenovirus can cause significant illness, it doesn't usually lead to the intensity of sickness and the death rates seen with flu.

Rapid flu tests can help distinguish whether a specific illness is due to influenza or another virus, such as adenovirus, but the point remains: If a person becomes dehydrated or if his or her mental state changes, seek emergency help. Neither illness should be taken lightly.

Years of Physical Farm Labor Likely Cause of Tingling in Hand

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: I'm a 75-year-old man who's done hard physical farm labor since I was a young boy. Now I have painful tingling, burning and numbness in my right palm and fingers. It disrupts my sleep and makes it difficult to hold a pencil. A hand brace doesn't help. Is it carpal tunnel syndrome? What can I do?

Dear Reader: Of course, I can't make a diagnosis without a proper examination -- and I would encourage you to seek one from your physician -- but your symptoms have all the hallmarks of carpal tunnel syndrome. This syndrome occurs because of compression of the median nerve at the wrist. As you look at the wrist with the palm side up, feel the multiple tendons in this portion of the wrist. The median nerve has to share space in the area called the carpal tunnel with nine of these tendons. When the wrist or the tendons within the carpal tunnel become inflamed, the median nerve gets compressed.

Because the median nerve supplies sensation to the thumb, index and middle fingers, compression of it can cause abnormal sensations, such as tingling, burning or even a loss of sensation. The median nerve also helps control the muscles of the thumb and, to some degree, the index and middle finger, so compression can lead to a loss of coordination and difficulty holding objects with the hand. This is most evident when using the thumb to hold an object such as a pencil or a cup. Many people with carpal tunnel syndrome have reported dropping cups.

The burning/tingling sensation in the hand is often noted upon waking -- sometimes causing the waking -- because the hands tend to flex at the wrist during sleep, leading to compression of the median nerve.

Repetitive and forceful use of the hand and wrist is a primary risk factor for carpal tunnel syndrome, as is working with tools that vibrate or that keep the hands in a fixed posture. Lifelong work in farm labor does have physical benefits, but it can take a toll as well.

Additional risk factors include diabetes, low thyroid hormone levels and rheumatoid arthritis, all of which can lead to carpal tunnel syndrome.

A wrist brace is a good first treatment for carpal tunnel syndrome because it stops the hand from flexing at the wrist, further compressing the median nerve. The next step would be physical therapy, though you should continue to use the brace at night. Treatments such as acupuncture and ultrasound therapy have shown some benefit in easing the symptoms of carpal tunnel syndrome, but more study is needed.

Steroid injections into the wrist can decrease swelling around the median nerve, usually providing a short-term benefit of one to three months. Physical therapy can enhance the benefit, but truly lasting improvement will generally occur with surgery that opens up the space around the median nerve.

Follow up with your doctor regarding these symptoms. He or she may suggest nerve-conduction studies to verify carpal tunnel syndrome and recommend a specific therapy that meets your needs.
