Information for Patients


Diphtheria is a serious bacterial infection. You can catch it from a person who has the infection and coughs or sneezes. You can also get infected by coming in contact with an object, such as a toy, that has bacteria on it.

Diphtheria usually affects the nose and throat. Symptoms include

  • Sore throat
  • Swollen glands in the neck
  • Fever
  • Weakness

Your doctor will diagnose it based on your signs and symptoms and a lab test. Getting treatment for diphtheria quickly is important. If your doctor suspects that you have it, you'll start treatment before the lab tests come back. Treatment is with antibiotics.

The diphtheria, pertussis, and tetanus vaccine can prevent diphtheria, but its protection does not last forever. Children need another dose, or booster, at about age 12. Then, as adults, they should get a booster every 10 years. Diphtheria is very rare in the United States because of the vaccine.

Kidney Diseases

Also called: Renal disease

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include

  • Cancer
  • Cysts
  • Stones
  • Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.
