I have a transplant kidney. My CMV test is positive. I used ganciclovir for 14 days, but what does it do?

I have a transplant kidney. My CMV test is positive. I used ganciclovir for 14 days, but what does it do?

Needs clarification: If your CMV antibody (IgG) test was (+), it indicates that you had a prior exposure to the virus but does not mean an active infection. In most renal transplant recipients, anti-viral medication is usually given to prevent CMV reactivation. If your blood PCR test was (+) for CMV, it indicates active presence of the virus in the blood and its tx requires ganciclovir (IV) or valganciclovir (oral). ...Read more

Herpes zoster tx: The standard approach to herpes zoster opthalmicus is to treat with antiviral therapy using a systemic drug like acyclovir, valacyclovir or famciclovir. However, gangciclovir ophthalmic gel is still indicated for treatment of herpes zoster opthalmicus. Treatment depends on the symptoms, because if there are systemic shingles symptoms present, a systemic antiviral should be started. ...Read more

Why do some children have allergies?

Why do some children have allergies?

Exposure + Genes: One needs both a genetic component and "exposure" to a said allergen to develop an allergy. There is a growing support over the past 20 years, that growing up in an environment which is "too clean" can also lead to development of allergies down the road. Either way, allergies are on the rise. ...Read more

I have an allergy to nuts and I was wondering if my children would also be allergic?

I have an allergy to nuts and I was wondering if my children would also be allergic?

Nut allergy: Maybe. Your children may have inherited genes from you that make them more likely to develop an allergy, but they do not inherit a specific allergy to a food e.g. Nuts. The children have to be exposed to food proteins in the diet, before an allergy can develop. Once one develops an allergy then they are always allergic and need proper medical attention to prevent severe problems. ...Read more

How do docs test children for indoor & outdoor allergies?

Allergy tests: There are several types of testing. Some involve certain types of blood tests. Another method is to do a series of skin tests done by pricking the skin and applying different allergens. Other tests are provocative tests that can involve challanging the patient with allergic materials. Testing should be done by doctors specializing in allergy to obtain the best results. ...Read more

Can a parents allergies be passed on to their children?

Can a parents allergies be passed on to their children?

Not exactly: The ability to react to certain proteins in an allergic way is passed on from parents to their children, but a specific allergy is not. So if a mom is allergic to pollen and the dad is allergic to fire ants, their child may develop allergies but it may be to a food instead. If 1 parent has allergies, the child is 50% likely to develop allergies, but it's a 75% chance if both parents are allergic. ...Read more

Chronic cough in children associated with Flonase allergy?

Chronic cough in children associated with Flonase allergy?

Doubtful: I don't think a child would be allergic to the nasal steroid spray flonase. There are certainly children whose cough may not respond to treatment with flonase, but the reason is most likely a mis-diagnosis rather than an allergy to it. One needs to think about an infectious cause, asthma or possibly reflux to name a few reasons for lack of response to flonase. ...Read more

For children's allergies should you combine zyrtec and claritin (loratadine)?

For children's allergies should you combine zyrtec and claritin (loratadine)?

Pick one: While both zyrtec (cetirizine) and Claritin (loratadine) are approved for treatment of allergies in children, it is rarely necessary to use both at the same time. In my experience, Claritin works for many and zyrtec works for most patients. While there is little harm to combining these, it doesn't add to the effectiveness. ...Read more

Is it possible that I give my two-year-old children's Benadryl (diphenhydramine) for seasonal allergies?

Is it possible that I give my two-year-old children's Benadryl (diphenhydramine) for seasonal allergies?

Yes: Yes, you can give your 2 year old child Benadryl (diphenhydramine) for allergy symptoms. Its onset is fast within 15-60 minutes and it lasts for about 4-6 hours. Otc zyrtec's onset is also fast and it lasts for 24 hours. Keep in mind that those medications can control mild allergy symptoms. If your child still suffers from the disease after taking otc meds, you might want to bring him or her to see an allergist. ...Read more

Took 2tsp of children's Benadryl (diphenhydramine) for my allergies, but forgot that I had 3 glasses of 5% dessert wine 3 hours earlier. Should I worry?

Not necesarily: I wouldn't drive a car or operate tools or machinery for another 6-8 hours, but this exposure would just make someone groggy. The time needed to metabolize the alcohol suggests at least half was gone before the medicine was taken, and the overlap is not worrisome. ...Read more

My husband and I accidentally gave our 4 yr old son, who weighs 42lbs, a double dose of childrens benadryl (diphenhydramine) for his allergies (chewable tablets 12.5mg)?

My husband and I accidentally gave our 4 yr old son, who weighs 42lbs, a double dose of childrens benadryl (diphenhydramine) for his allergies (chewable tablets 12.5mg)?

?? no numbers??: The only way for me to comment on the dose is if you list what you gave. Two 12.5 mg tabs in a 42 lb kid might make him groggy but shouldn't hurt in the long run. Four tabs would put him to sleep and he'd be out for a few hours. Luckily the med clears the body in 4-8 hours. ...Read more

Do children grow out of allergies?

Do children grow out of allergies?

Yes: Not all of the food allergies are created equal. Food allergies like dairy, egg, wheat tend to be outgrown. Tree nut and peanut are less likely (although recent studies suggest that 20-30% outgrow the peanut allergy). Environmental allergies tend to "grow on you" with time. Note: the allergy test may remain positive despite the child having outgrown the allergy. Consult with an allergist. ...Read more

How often should children be tested for allergies?

How often should children be tested for allergies?

It depends: It really depends on the age of the child, and whether you're talking about food or environmental allergies. I generally will skin test children over age 2 for environmental allergies, while many younger kids need food testing. In terms of frequency, children with environmental allergies may benefit from repeat testing after 2 years, as their allergies can change as they get older. ...Read more

Why is it that so many children have allergies nowadays?

Why is it that so many children have allergies nowadays?

Hygiene hypothesis: The immune system has two opposing arms, one makes protective antibodies against bacteria and viruses, the other makes allergic antibody. One theory is that early antibiotic use disrupts the gut flora which tips the scale away from fighting infection and more toward making allergic antibodies. Clean environments might be at fault as well, farm kids don't get allergies as much as city kids. ...Read more

Does a cough come with allergies in children?

Sometimes: But not all the time. Nasal allergies are not a frequent cause of a really bad persistent cough. In a child with allergies and a really bad cough (assuming no fever) I would be concerned about a reactive airway/asthma type condition. If the child also had eczema I would be even more concerned. ...Read more

How can I prevent my children from getting allergies?

Breastfeed!: Breastfeeding is shown to be protective for children with a strong family history of allergies. If unable to breast feed, try a hypoallergenic formula such as "nutramigen" or "alimentum". Try to avoid introducing baby foods until 4-6 months of age; once you do, introduce them slowly. Interestingly, exposure to dogs & cats appears to reduce the risk of becoming allergic to those household pets! ...Read more
