Lymphocytic Choriomeningitis Virus (LCMV)

A virus carried by hamsters and wild or lab mice that is not harmful to adults, but that can cause birth defects in unborn children whose mothers contract the virus. LCMV was first identified in 1933 in a woman who was thought to have a form of ENCEPHALITIS. In 1955 it was first recognized in the United Kingdom as a virus that could cause congenital disease. Since then, individual cases of congenital LCMV infection have been identified in Germany, France, Lithuania, and across the United States.
Mice and hamsters are the primary sources of LCMV infections. Humans acquire this virus by direct contact with infected rodents or by inhaling the virus. So far, more than 49 infants around the world have been diagnosed with congenital LCMV. However, experts really are not sure how many infants have been affected by LCMV before birth because doctors do not routinely look at LCMV as a possible cause of congenital blindness or retardation. In one instance, twin girls from Cochise County, Arizona, were born to a mother who had unknowingly contracted LCMV during pregnancy. One girl was born with vision problems and the other has seizures and severe developmental delays. More than 90 percent of the babies who have contracted the LCMV virus before birth have had adverse effects, the most common of which were vision problems. Other problems include neurological conditions such as CEREBRAL PALSY, MENTAL RETARDATION, SEIZURES, and decreased visual acuity.
A pregnant woman with a pet hamster should have someone else take care of it during the pregnancy. If cleaning up after wild mice, pregnant women should wear gloves and spray the area with water to avoid the possibility of wafting the virus into the air. Pregnant women who work with mice in a laboratory setting should have the mice tested for LCMV.

There are several problems with the liver that may affect children, including JAUNDICE, cholestasis, enlarged liver, portal hypertension, ascites or liver encephalopathy, and liver failure.
Diagnosis
When diagnosing liver disease, the pediatrician conducts a physical exam and checks the child’s symptoms. In addition, a doctor may order a liver biopsy, liver enzyme tests, an ultrasound, or a computerized tomography (CT) scan.
Problems
Jaundice This condition refers to a yellow discoloration of the skin and whites of the eyes due to an abnormally high level of bilirubin (bile pigment) in the blood. In newborns, jaundice is often caused by the breakdown of a large number of red blood cells, which can simply be treated by exposure to special lights and temporary bottle feeding. Otherwise, high levels of bilirubin may be caused by inflammation or other abnormalities of the liver cells, or blockage of the bile ducts. Jaundice is usually the first—and sometimes the only—sign of liver disease.
Cholestasis This condition refers to reduced or blocked bile flow that may occur inside or outside the liver (or in both places). Symptoms of problems with bile flow may include jaundice, dark urine, pale stool, bone loss, easy bleeding, itching, spidery blood vessels in the skin, enlarged spleen, fluid in the abdominal cavity, chills, pain, or enlarged gallbladder. Cholestasis can be caused by HEPATITIS, metabolic liver diseases, drug effects, a stone in the bile duct, narrowed bile duct, biliary atresia, or inflamed pancreas.
Liver enlargement An enlarged liver usually heralds some type of liver disease. While a slightly enlarged liver may cause no symptoms, a significant problem may trigger feelings of abdominal discomfort.
Portal hypertension Abnormally high blood pressure in the portal vein linking the intestine to the liver that may be due to higher blood pressure in the portal blood vessels or resistance to blood flow through the liver. Portal hypertension can trigger the growth of new blood vessels bypassing the liver, bringing blood from the intestine directly to the general circulation. When this occurs, substances that the liver normally would filter out instead pass into general circulation. Symptoms of portal hypertension may include a distended abdominal cavity, spider veins, and bleeding of the veins at the lower end of the esophagus and in the stomach lining.
Ascites This condition refers to fluid buildup in the abdominal cavity caused by fluid leaks from the vessels on the surface of the liver and intestine. Ascites due to liver disease usually accompanies other liver disease characteristics such as portal hypertension. Symptoms may include a distended abdomen, discomfort, and shortness of breath.
Liver encephalopathy This condition is caused by the deterioration of brain function due to toxic substances building up in the blood that are normally removed by the liver. Liver encephalopathy is also called portal-systemic encephalopathy, hepatic encephalopathy, or hepatic coma. Symptoms may include changes in mood, logical thinking, personality, and behavior; impaired judgment; drowsiness and confusion; sluggish speech and movement; disorientation; loss of consciousness and coma.
Liver failure This severe deterioration of liver function occurs when a large portion of the liver is damaged. Symptoms may include jaundice, bruising or bleeding, abdomen distention, impaired brain function, poor weight gain and growth, fatigue, weakness, nausea, and appetite loss.

Listeriosis

admin 20 January, 2009
(0) Comment
A food-borne illness that may cause no symptoms in healthy children but is especially dangerous to newborns and very young children. Listeriosis occurs in about 7.5 cases for every one million people. Once thought to be exclusively a veterinary problem, it was identified as a human disease in 1981 when a Canadian outbreak was linked to tainted coleslaw made from cabbage grown in soil fertilized with Listeria-infected sheep manure. Four years later another outbreak was traced to Mexican-style soft cheese in California, which sickened 150 people, including many pregnant women, resulting in stillbirths.
From 1987 to 1992 the government recalled cooked products from 27 firms, including hot dogs, bologna, and other luncheon meat, chicken salad, ham salad, sausages, chicken, sliced turkey breast, and sliced roast beef. Cheese, dairy, sandwich, prepared salad, and smoked fish recalls from 1987 to 1992 included 516 different products from 105 firms.
Cause
Listeriosis is caused by one species in a group of bacteria called Listeria monocytogenes found in cow’s milk, animal and human feces, soil, and leafy vegetables. In the past 10 years there have been several outbreaks that seem to have been linked to eating deli meats and soft cheeses such as feta, blue-veined cheeses, and some types of Mexican cheese. One recent study found that 2 percent of hot dogs tested contained the bacterium L. monocytogenes. Children with impaired immune systems also can catch the disease from undercooked chicken.
The bacteria is remarkably tough, resisting heat, salt, nitrite, and acidity much better than many other organisms. It can survive on cold surfaces and can multiply slowly at temperatures as low as 34°F. Freezing the food will stop the bacteria from multiplying, and commercial pasteurization will eliminate the organism in dairy products. Listeria does not change the taste or smell of food.
When Listeria is found in processed products, the contamination probably occurred after processing, rather than due to poor heating or pasteurizing.
Babies can be born with listeriosis if their mothers ate contaminated food during pregnancy. Pregnant women are 20 times more likely than other healthy adults to get the disease; about a third of all cases occur during pregnancy. However, it is newborns rather than their mothers who suffer the most serious effects of infection during the pregnancy.
Symptoms
If the fetus is affected early in the pregnancy, the baby will probably be born prematurely. Infants in this situation are usually quite ill, with low birth weight, breathing problems, blue skin, and low body temperature. If the baby survives, there may be a bloodstream infection or MENINGITIS. Half of these babies infected with Listeria die, even if treated.
Fetuses affected later in the pregnancy may be carried to term and be born at normal weight. If infected during delivery, the infants may develop meningitis; if so, 40 percent die. Some surviving babies who contract meningitis may have permanent brain damage or mental retardation.
Most normal, healthy children who become infected with the bacteria suffer few symptoms, or may experience a flu-like illness with fever, muscle aches, and nausea or diarrhea. If infection spreads to the nervous system, however, it can cause a type of meningitis.
Diagnosis
There is no routine screening test for susceptibility during pregnancy as there is for rubella and other infections. A blood or spinal fluid culture will reveal the infection.
Treatment
Antibiotics given to the pregnant mother can prevent disease in the fetus. Babies with listeriosis receive the same antibiotics as adults, although a combination of antibiotics may be used until diagnosis is certain. However, even with prompt treatment, some infections result in fetal death.
Prevention
In order to protect unborn children, pregnant women are advised to avoid deli counter foods and soft cheeses. There is no risk in hard cheese, processed slices, cottage cheese, or yogurt.
Those at risk should cook hot dogs to 160°F for several minutes to avoid contamination. Hot dogs at restaurants, ball parks, and so on, should be avoided, since cooking temperatures cannot be verified.

Lice

Crawling insects that feed on human blood that are a common annoyance in elementary schools and day-care centers. Head lice live on and suck blood from the scalp, leaving red spots that itch intensely and can lead to skin inflammation and infection. The females lay a daily batch of pale eggs, called “nits,” that attach to hairs close to the scalp. The nits hatch in about a week, and the adults can live for several weeks.
Head lice are found among people of all walks of life. About six million cases occur each year among U.S. schoolchildren between ages three and 12, even among those who shampoo daily. Children are most often infected via direct contact at school by sharing hats, brushes, combs, or headrests. Pets cannot get head lice.
Neighborhood parents and the child’s school, camp, or child-care provider should be notified of the infestation. Children should be checked once a week for head lice.
Head lice lay eggs at the base of hairs growing on the head. While nits can be found anywhere on the hair, they are especially common behind the ears and at the back of the neck. Because lice move so quickly, it is usually the oval-shaped nits that are seen on the hair shaft. Nits are yellow when newly laid, turning to white once they hatch. They appear to be “glued” at an angle to the side of the hair shaft and hatch within eight days. The empty eggshells are carried outward as the hair grows.
Nits should not be confused with hair debris such as fat plugs or hair casts. Fat plugs are bright white irregularly shaped clumps of fat cells stuck to the hair shaft. Hair casts are long, thin cylindershaped segments of dandruff encircling the hair shaft; they are easily dislodged.
Head lice and nits also can be found on eyebrows and eyelashes. If one person in a family has head lice, all family members should be checked. However, only those who are infested should be treated with lice pesticide.
Diagnosis
Lice infestations are diagnosed by the presence of nits. By calculating the distance from the base of the hair to the farthest nits, it is possible to estimate how long the infestation has been.
Treatment
In order to get rid of head lice, all nits must be removed. Since no lice pesticide kills all nits, remaining nits left on the hair must be removed to eliminate the need for more treatments. Nits can be removed with a special nit removal comb, with baby safety scissors, or with the fingernails.
Drug treatment Lotions containing malathion or carbaryl kill lice quickly; the lotion should be washed off 12 hours after application, followed by combing the hair with a fine-toothed comb to remove dead lice and nits. Shampoos containing malathion or carbaryl are also effective if used repeatedly over several days. Combs and brushes should be plunged into very hot water to kill any attached eggs.
The National Pediculosis Association discouraged the use of lindane products (such as Kwell) because they appear to be potentially more toxic and no more effective than other treatments. Still, no product kills 100 percent of nits. Lice medications are not intended to be used on a routine or preventive basis.
All lice-killing medications are really pesticides and therefore should be used with caution. A health-care expert should be consulted before using or applying pesticides when the child has lice or nits in the eyebrows or eyelashes or has other health problems (such as allergies). Because head lice pesticides can be absorbed into the blood, they should not be used on open wounds on the scalp. These medications should not be used at all on infants and should be used with caution on children under age two. Instead, lice and nits can be removed by hand on very young children while wearing gloves.
The product should be used over a sink (not applied in a tub or shower) to minimize pesticide exposure to the rest of the body. The child’s eyes should be kept covered while administering the pesticide.
Environmental treatments Bedding and recently worn clothing also should be washed in hot water and dried in a hot drier. Combs and brushes should be cleaned and then soaked in hot water for 10 minutes. Vacuuming is the best way to remove lice and attached nits from furniture, mattresses, rugs, stuffed toys, and car seats. According to the National Pediculosis Association, lice sprays should not be used.
Body Lice
Body lice live and lay eggs on clothing next to the skin, visiting the body only to feed. Body lice affect those who rarely change their clothes and are not a serious problem for American children. Body lice can be killed by placing infested clothing in a hot drier for five minutes, by washing clothes in very hot water, or by burning.

Lazy Eye

The common term for amblyopia, in which a child’s reduced vision is not caused by any eye disease and is not correctable by glasses or contact lenses. Instead, the problem is caused by the brain’s refusal to acknowledge the images seen by the lazy eye, causing reduced vision. This almost always affects only one eye, although vision may be reduced in both. It is estimated that three percent of children under six have some form of amblyopia. If not detected and treated early in life, amblyopia can cause a permanent loss of vision. Detection and correction before the age of two is the best way to restore normal vision. Between 2 and 3 percent of all children have lazy eye.
Cause
All babies are born with poor eyesight, but as they grow, their eyesight improves. Good eyesight needs a clear, focused image that is the same in both eyes. If the image is not clear in one eye, or if it is not the same in both eyes, the vision pathways will not develop correctly, or may get worse.
Amblyopia usually is caused by either a misalignment of a child’s eyes (such as crossed eyes) or a difference in image quality between the two eyes (one eye focusing better than the other). In both cases, one eye becomes stronger, suppressing the image of the other eye. If this condition persists, the weaker eye may become useless. Anything that interferes with clear vision in either eye during the critical period from birth to six years of age will cause amblyopia.
Amblyopia vs. Strabismus
Although many people call strabismus (crossed eyes) “lazy eye,” in fact they are two different conditions; strabismus is one cause of amblyopia. Amblyopia can result from a constant strabismus in which the right or left eye turns all of the time, but alternating strabismus in which an eye only sometimes turns rarely causes amblyopia.
Diagnosis
Since amblyopia usually occurs in only one eye, children may not notice the condition, and because many parents do not have their infants or toddlers take a comprehensive vision exam, many children go undiagnosed until they have their eyes examined later. The most important diagnostic tools are special visual acuity tests.
Treatment
The earlier the treatment, the better the opportunity to reverse the vision loss. Amblyopia can be treated between the ages of two and six, but the success rate decreases with age. The best results from treatment occur between six months and two years.
Glasses are commonly prescribed to improve focusing or misalignment of the eyes. Surgery may be performed on the eye muscles to straighten the eyes if other means have not been successful.
Eye exercises may be recommended either before or after surgery to correct faulty visual habits associated with strabismus and to teach comfortable use of the eyes. The correction may be followed by patching or covering one eye for a few weeks to as long as a year. The better-seeing eye is patched, forcing the “lazy” one to work, thereby strengthening its vision.
Eye drops or ointment may be used to blur the vision of the good eye in order to force the weaker one to work, although this is generally a less successful approach than eye patching.
Although true amblyopia cannot be cured after the age of six, treatment for older children still can usually improve vision. Treatment of amblyopia after the age of six requires more effort and includes vision therapy. If not treated early enough, an amblyopic eye may never develop good vision and may even become functionally blind.

Latex Allergy

Allergic responses to latex (rubber) products are fairly common among children and can range from mild irritation to life-threatening reaction. It is an extremely common compound found in many products, including underwear bands, rubber gloves, toys, elastic bandages, baby bottle nipples, pacifiers, and balloons. Anyone with a latex allergy should avoid exposure to all products that contain latex, but children most at risk are those with birth defects requiring multiple surgeries early in life. Between two and eight percent of the population are allergic to latex.
The first incidents of latex allergy in the United States were reported in 1988. Numbers had increased to at least 500,000 by 1992. Between 1990 and January 1991, nine children at a children’s hospital in Milwaukee had anaphylactic reactions within 30 minutes after general anesthesia was started but before any surgical incisions had been made. The latex connection was the anesthesia equipment and intravenous catheters. Eight of the children required intensive care.
Symptoms
Typical symptoms include watery eyes, wheezing, hives, rash, swelling, and, in severe cases, anaphylaxis. (In anaphylactic shock, a child can develop shortness of breath, swollen lips, and throat, heart, and breathing problems within minutes.) These responses can occur when items containing latex touch the skin, the mucous membranes (the mouth, genitals, bladder, or rectum), open areas, or bloodstream (especially during surgery). Lips and the face may swell after contact with latex balloons.
Cause
A latex allergy occurs when the immune system reacts to proteins found in latex, triggering a defensive reaction that can cause unpleasant and, in some cases, life-threatening symptoms. However, certain children are at greater risk of becoming allergic to latex. Those at higher risk include children who are frequently exposed to latex. As many as 65 percent of children with spina bifida have latex allergy. More than 25 percent of children with spinal injuries are allergic to latex, as are 33 percent of children with multiple congenital defects (especially urinary tract defects) and any child who has had three or more surgeries. It is the repeated exposure to latex (usually through catheterization) that sensitizes children to latex. This progressive allergy worsens with increased exposure.
Children who develop latex allergy also can be sensitive to food allergens. A number of fruits, vegetables, nuts, and cereals contain proteins that are similar to the proteins found in latex. A child’s body can generalize an allergic reaction from one protein to another similar one (cross-reactivity). The following foods cross-react with latex: avocados, bananas, pineapples, apricots, grapes, kiwis, tomatoes, papayas, passion fruit, cherries, figs, peaches, nectarines, plums, celery, raw potatoes, hazelnuts, and chestnuts.
Diagnosis
A sensitivity to latex can be diagnosed from a review of past medical history, a physical exam, and blood tests for latex-specific IgE antibodies. Test results define the presence of sensitivity, but once a sensitivity is present, IgE antibodies cannot be used to predict how severe a reaction will occur.
Treatment
There is no cure for a latex allergy. Children at high risk can prevent the development of latex allergy by avoiding latex products in all areas. If a child has already developed latex allergy, avoidance may lessen the response. In order to protect themselves, students with latex allergies should carry nonlatex gloves at all times for health-care professionals to use during both routine examinations and emergency procedures. School nurses should have a supply of nonlatex gloves available for use. Highly allergic children also should wear a Medic Alert bracelet and carry an emergency epinephrine kit (Epipen) in case they are accidentally exposed to latex and go into anaphylactic shock. The school nurse, playground aides, and classroom teacher should be aware of what to do in case of an allergic reaction. The physical education instructor should also be familiar with the student’s allergy because equipment is often made from rubberbased products. Cafeteria workers may need to adjust their food preparation practices to address the student’s sensitivity.

Laryngitis

An inflammation and swelling of the voice box (larynx) and the area around it, usually associated with hoarseness or loss of the voice. The problem is most common in late fall, winter, or early spring.
Cause
The voice box contains the vocal cords and is located at the top of the airway to the lungs. When the vocal cords become inflamed or infected, they swell, which can cause hoarseness and may even obstruct the child’s airway.
The most common form of laryngitis is caused by a viral infection, although it also may be caused by a bacterial infection or the common cold, bronchitis, flu, or pneumonia. Common laryngitis is not normally associated with any breathing difficulty.
Several other forms of laryngitis in children— CROUP and EPIGLOTTITIS—can lead to fatal obstruction of the respiratory tract. Other causes of laryngitis include laryngeal polyps, laryngeal paralysis, precancerous changes of the throat, malignant tumors, allergies, and trauma.
Symptoms
Symptoms include a recent upper respiratory infection, fatigue, hoarseness, fever, and swollen lymph nodes or glands in the neck.
Treatment
Since most common laryngitis is viral, treatment with antibiotics is generally not necessary. Resting the voice helps to reduce inflammation of the vocal cords, and a humidifier may ease the raw feeling sometimes associated with laryngitis. Decongestants and painkillers may ease symptoms from the upper respiratory infection.
Call a Doctor
Rarely, severe respiratory distress may develop. A doctor should be consulted if the child has trouble breathing or swallowing, or if a small child is drooling. A doctor should be called if a child less than three months old is hoarse, or if an older child has been hoarse for more than a week.
Prevention
Avoiding upper respiratory infections during cold and flu season may help prevent laryngitis. This can be done by thorough hand-washing, avoiding others with infections, and wiping surfaces in the home when people are sick.

Knock-Knees

Many children show a moderate tendency toward knock-knees between the ages of four and six as the body goes through a natural shift of alignment during the first years of life. After this period, the body tends to straighten. Many perfectly normal children are bowlegged and then become knock-kneed during normal development. Special shoes or wedges make no difference. Only when an inward turning of the knees is severe and associated with other problems is further evaluation or treatment necessary.
Most pediatricians can recognize when the condition is severe enough to warrant special care, but parents may want to seek a specialist’s opinion if they believe their child’s feet or legs are not developing normally. BOWED LEGS, FLATFEET, knockknees, PIGEON TOE, and TOE-WALKING are all examples of normal variations of the human anatomy that rarely require treatment.
