Hydrocephalus means "fluid on the brain". It means excess fluid in the brain area and can be caused by a birth defect, an injury, or stroke. In infants, it is characterized by a large increase in head size, which if not treated, can become permanent. It is treated by surgically installing shunts which drain the fluid away.

∙ 14y agoIn embryology hyrocephalus is when the top of the neural tube swells at the top due to an increase in cerebrospinal fluid. It forms fluid filled vesicles which will go on to form the brain (or as is my understanding =s)

Urinary tract infection - children?
DefinitionA urinary tract infection (UTI) is a bacterial infection of the urinary tract. This article discusses UTIs in children.The urinary tract includes the:BladderKidneysUreters -- the tubes that take urine from each kidney to the bladderUrethra -- the tube that empties urine from the bladder to the outsideSee also:Catheter-associated UTIUrinary tract infection - adultsAlternative NamesUTI - children; Cystitis - children; Bladder infection - children; Kidney infection - children; Pyelonephritis - childrenCauses, incidence, and risk factorsUrinary tract infections (UTIs) can occur when bacteria find their way into the bladder or the kidneys. These bacteria are normally found on the skin around the anus or sometimes around the vagina.Normally, there are no bacteria in the urinary tract itself. However, certain things can make it easier for bacteria to enter or stay in the urinary tract. These include:A problem in the urinary tract, called vesicoureteral reflux, which is usually present at birth. This condition allows urine to flow back up into the ureters and kidneysBrain or nervous system illnesses (such as myelomeningocele, spinal cord injury, hyrocephalus) that make it harder to completely empty the bladderBubble baths or tight fitting clothes (girls)Changes or birth defects in the structure of the urinary tractNot urinating (peeing) often enough during the dayWiping from back (near the anus) to front after going to the bathroom. In girls, this can bring bacteria to the opening where the urine comes outUTIs are more common in girls, especially around age 3 when they first begin toilet training. In boys who are not circumcised, the risk for UTIs is slightly higher before the first birthday.SymptomsYoung children with UTIs may only have a fever, poor appetite, vomiting, or no symptoms at all.Most urinary tract infections in children only involve the bladder. If the infection spreads to the kidneys, it is called pyelonephritis and may be more serious.Symptoms of a bladder infection in children include:Blood in the urineCloudy urineFoul or strong urine odorFrequent or urgent need to urinateGeneral ill feeling (malaise)Pain or burning with urinationPressure or pain in the lower pelvis or lower backWetting problems after the child has been toilet trainedSymptoms that the infection may have spread to the kidneys include:Chills with shakingFeverFlushed, warm, or reddened skinNauseaPain in the side (flank) or backSevere pain in the belly areaVomitingSigns and testsA urine sample is needed to diagnose a UTI in children. The sample is examined under a microscope and sent to a lab for a urine culture.In children who are not toilet trained, getting a urine sample can be difficult. The test cannot be done using a wet diaper. Possible ways to collect a urine sample in very young children include:Urine collection bag -- A special plastic bag is placed over the child's penis or vaginal area to catch the urine; this is not the best method because the sample may become contaminated.Catheterized specimen urine culture -- A plastic tube (catheter) placed into the tip of the penis in boys, or directly into the urethra in girls, collects urine directly from the bladder.Suprapubic urine collection -- A needle is placed through the skin of the lower abdomen and muscles, into the bladder, and used to collect urine.If this is your child's first UTI, special imaging tests may be done to determine why the infection happened, or to see if there is any kidney damage. Tests may include:Kidney ultrasoundX-ray taken while the child is urinating (voiding cystourethrogram)These studies may be done while the child has an infection, but most often it's done weeks to several months afterward.Your doctor will consider many things when deciding if and when a special study is needed, including:Is the child younger than 6 months?Has the child had infections in the past?Is the infection severe?Does the child have other medical illnesses?Does the child have a problem with the spinal cord or defects of the urinary tract?Has the child responded quickly to antibiotics?TreatmentIn children, UTIs should be treated quickly with antibiotics to protect the developing kidneys. Any child under 6 months old or who has other complications should see a specialist immediately.Younger infants will usually stay in the hospital and be given antibiotics through a vein. Older infants and children are treated with antibiotics by mouth. If this is not possible, they are admitted to the hospital where they are given antibiotics through a vein.It is important that your child drink plenty of fluids during the time they have a urinary tract infection.Some children may be treated with antibiotics for long periods of time (as long as 6 months - 2 years), or they may be prescribed stronger antibiotics.The health care provider may also recommend low-dose antibiotics after the first symptoms have gone away. This type of treatment is less common now than it once was.Antibiotics commonly used in children include:Amoxicillin or amoxicillin/clavulanic acid (Augmentin)CephalosporinsDoxycycline (should not be used in children under age 8)NitrofurantoinTrimethoprim-sulfamethoxazoleFollow-up urine cultures may be needed to make sure that bacteria are no longer in the bladder.Expectations (prognosis)Most children are cured with proper treatment. The treatment may continue over a long period of time.The long-term consequences of repeated UTIs in children can be serious. However, these infections can usually be prevented.ComplicationsHigh blood pressureKidney abscessKidney infection (pyelonephritis)Renal insufficiency or kidney failureSwelling of the kidneys (hydronephrosis)Calling your health care providerCall for an appointment with your health care provider if your child's UTI symptoms continue after treatment or come back more than twice in 6 months.Call your health care provider if the child's symptoms get worse, or new symptoms develop, especially:Back pain or flank painBad-smelling, bloody, or discolored urineFever of 100.4Fahrenheit (38Celcius) rectally in infants, or over 101Fahrenheit (38.3Celcius) in childrenLow-back pain or abdominal pain (especially below the belly button)Persistent feverUnusually frequent urination or frequent urination during the nightVomitingPreventionAvoid giving your child bubble bathsHave your child wear loose-fitting underpants and clothingIncrease your child's intake of fluidsKeep your child's genital area clean to prevent bacteria from entering through the urethraTeach your child to go the bathroom several times every dayTeach your child to wipe the genital area from front to back to reduce the chance of spreading bacteria from the anus to the urethraLong-term use of preventive (prophylactic) antibiotics may be recommended for some children who are prone to chronic UTIs.ReferencesMontini G, Rigon L, Zucchetta P, et al.
