What is a UTI?

A UTI is an infection of the urinary tract or the bladder.

What are the symptoms?

Fever is the number one symptom. Parents and older children should also be looking out for a different smell or color change when urinating. In school-aged children and teens, they may complain that it hurts when they go to the bathroom. Older children may experience fever, vomiting, abdominal pain, or even back pain. Teens may also notice they are urinating more frequently and may have a burning sensation when they go to the bathroom.

Can you get a UTI without having underlying issues?

Yes. Drs. Combs and Chong both agree it’s common for girls to get a UTI without underlying medical issues. If proper hygiene is followed, they believe UTIs often happen because of female anatomy and how close everything is in that specific area.

Are UTIs treatable?

Yes, UTIs are treatable with antibiotics. If a UTI festers for a long period, it can cause a more severe infection that may have to be treated with IV antibiotics as opposed to oral.

Are boys or girls more susceptible to the infection?

Girls are more likely to get a UTI because bacteria from the outside of the body can get inside the urethra, which is shorter in girls. In younger girls who are still in diapers, UTIs can happen if they have excessive diarrhea. Older girls can contract UTI’s from not wiping front to back, or practicing poor hygiene. The highest risk for a UTI is in girls, followed by uncircumcised boys, and then boys who are circumcised.

What advice would you give to parents?

Dr. Chong: Adequate fluid intake is important to help flush things out. For younger children, ensure that you’re teaching them how to wipe properly from front to back and do not allow them to sit and play in dirty bathwater for too long as that can cause irritation and lead to symptoms that can look like a UTI.

Dr. Combs: Stay hydrated as we begin to hit the summer months. Be sure to take a shower and change clothes or change out of any sweaty clothes if you’re not taking a shower. Moisture affects bladder health and female health.

Important to note:

UTI’s have similar symptoms to sexually transmitted infections (STI) such as gonorrhea and chlamydia. If your child is sexually active, you may want to get them checked out for a UTI and STIs.

How do you know when it is something else or when it could be more dangerous?

A report last week from the CDC described a cluster of infections caused by shigella, a bacteria that can cause severe diarrhea.

Shigella is common, causing an estimated 500,000 cases of diarrhea in the United States annually. But this group of infections is unique because it has been found to be resistant to the most common type of antibiotic used in adults used for shigella. Most cases have been located on the East and West coast and many have been associated with travel outside the United States.

Fortunately, there were no cases of this more severe form of shigella reported in Texas so I feel that we are pretty low risk at this point. I did want to take a second to tell you about warning signs that might alert you that diarrhea might be more than a stomach bug.

Here are some symptoms that might alert you that should trigger a call to your doctor:

1. Severe vomiting with decreased urine frequency or other signs of dehydration.
2. Fever more than 102.
3. Blood or mucous in the stool.
4. Severe belly pain.
5. Diarrhea that last more than one week.
6. Let your doctor know if your child has traveled recently.

What are Salmonella and Shigella?

Two of the most common bacterial causes of infection are salmonella and shigella. They are both fairly frequent causes of severe diarrhea in children.

They can both be transmitted by contaminated food or water but can also be spread from person to person. Salmonella is more frequently caused by transmission from contaminated food, but also can be contracted from infected reptiles. Shigella is more frequently acquired from other children and is much more contagious than salmonella.

(Just to give you an idea, stool of a child infected with shigella contains 100,000,000 bacteria per gram of stool. Ingesting just 200 bacterial cells is enough to cause infection. Because of this, outbreaks of Shigella are common in child-care settings.)

The most common symptoms with both infections are diarrhea, abdominal pain and fever. With shigella, fever is often higher and children are more likely to have blood or mucous in their stools.

For either infection, your doctor can run stool studies to confirm the diagnosis. This may not be necessary if there are known cases that the child has been exposed to.

Both infections will typically go away on their own in seven days or less. Most healthy children do not require antibiotics. I do not routinely recommend anti-diarrheal medications in children because they can prolong symptoms with some infections.

If you suspect your child has one of these infections, consult with your doctor and keep them out of day care until we are sure they will not put other children are risk.

I must get this question three to four times a day in the office and it's one of those things that keeps you up all night wondering what you should do. The answer, "There is no fever you should go to the ER for..."

That doesn't mean that children with fever don't sometimes need to go to the ER, but the height of the fever is not an indication that a late night drive and time in the ER wait is the right thing to do.

We always want to take the fever into the context of the following questions:

1) What are the other symptoms that the child is having?

• Runny nose, cough? Probably not.
• Abdominal pain? Depends on severity an location.
• Vomiting? Not if can keep some liquids down and still peeing.

2) What is the child's behavior like? Lethargic or active. Is the child laying around all day, not even really wanting to wake up to drink or do they perk up and act like they feel better at times (especially when their fever is down). If they are lethargic, bring them in.

3) Is the child drinking and peeing?  If so, then we will almost always recommend a call to the office over an ER trip.

Common fever myths:

"The child's brain will be fried if the temperature is over 105." Ummm. No. Temperatures that the body is generating on their own as a response to illness will not cause brain damage or any of the other things that your grandmother/neighbor/best friend said they would. We commonly have children with 105-106 temps walk in and out of our office smiling cause they got their stickers for being a good boy/girl.

"If the fever gets above 103 they will have a febrile seizure." Wrong again. In fact, most febrile seizures occur when the temperature is between 102 and 103. We don't know exactly why this is but it is thought that it is related to the rate that the temperature rises and not the absolute number that the temp gets to.

"The baby felt warm so she had a fever" or "The baby was really hot so the temperature must've been about 104." Sorry to the back of grandma's hand, but judging the temperature especially trying to put a number on it by touching a child's head is incredibly unreliable. I would prefer an axillary or temporal thermometer, or in the babies less than 3 months, I'll commonly ask for a rectal temp.

"He had a low grade temp of 99" or "99 is hot for him because he usually runs 96." “Low grade temp” should really be taken out of our vocabulary. They have done studies where they took children's temperatures several times a day and have found that any temp <100.5 in a child less then 3 months and <101 in an older child should not be considered fever. These are normal temperatures that can occur during the course of the day for any child who is healthy and has no reason to be running fever.

So, what temps should I call for?

• Any temp over 100 in a baby less than 3 months.
• Any temp in a child who is not drinking well and with decreased urine.
• Anything else that has you concerned.

The ultimate point is that we should not be afraid of fever. Fever is just another symptom in a long list of possible symptoms a child can have when they are sick. It means that we need to think about what is going on and watch the child close but resist the urge to panic!
